Description

Starting device and fire extinguishing apparatus

Technical Field

The invention relates to the technical field of fire extinguishing equipment, in particular to a starting device and fire extinguishing equipment comprising the same.

Background

In order to spray fire extinguishing agent to extinguish fire, the pressure storage type fire extinguishing equipment needs to fill a certain amount of gas with pressure into the container, and the pressure of the gas is generally 1.2MPa to 20 MPa. The whole fire extinguishing equipment consists of a fire extinguishing agent storage container, a container valve (bottle head valve), a pressure gauge, a fire extinguishing agent injection port, a signal feedback device and other parts, and the pressure storage type fire extinguishing equipment is stored under pressure for a long time, so that the connection part of the parts becomes a pressure leakage point. Once the pressure of the fire extinguishing equipment is leaked, the fire extinguishing agent cannot be normally sprayed out. Therefore, the pressure storage type fire extinguishing apparatus needs to be maintained and pressurized regularly. If the maintenance is not timely, the fire, especially public transport, happens at the moment, and the maintenance pressurization needs to be started to a station. If the pressure is relieved during the driving, the fire can not be extinguished just in case of fire, which can lead to crowd death and crowd injury with serious consequences.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

Example one

As shown in fig. 1, one embodiment of the present invention provides a starting apparatus 100. The starting apparatus 100 includes: a shell 1, a gas production device 2 and an initiation device 3.

Specifically, the gas generating device 2 comprises an integrated sealed container 21 and a driving medium 22 sealed in the sealed container 21, wherein the sealed container 21 is connected with the shell 1. The initiation device 3 is matched with the gas production device 2 and is used for opening the sealed container 21 so as to enable the driving medium 22 to be sprayed out of the sealed container 21 and form gas.

According to the starting device 100 provided by the embodiment of the invention, the driving medium 22 is packaged in the integrated sealed container 21, and when fire is needed to be extinguished, the sealed container 21 can be opened through the initiation device 3, so that the driving medium 22 is sprayed out of the sealed container 21 and gas capable of driving the extinguishing agent 220 to be sprayed out is formed, the gas can enter the extinguishing agent storage container 210 to quickly pressurize the extinguishing agent storage container 210, and further the extinguishing agent 220 is sprayed out under the action of pressure to extinguish the fire. Thus, the fire extinguishing agent 220 does not need to be stored under pressure, thereby fundamentally solving the pressure leakage problem of the existing pressure storage type fire extinguishing apparatus, not only saving the maintenance cost of periodical pressurization, but also improving the use reliability of the fire extinguishing apparatus 200.

Specifically, the starting device 100 comprises a housing 1, a gas generating device 2 and an initiating device 3. The gas generating device 2 is a non-explosive device and specifically comprises a sealed container 21 and a driving medium 22. The sealed container 21 is of an integrated structure, and the driving medium 22 is stored in the sealed container 21. When a fire occurs and a fire is to be extinguished, the sealed container 21 can be opened through the initiation device 3, and the sealed container 21 is rapidly decompressed when being opened, so that the driving medium 22 is sprayed in a gas form, the air pressure in the fire extinguishing agent storage container 210 is rapidly increased, and the fire extinguishing agent 220 is driven to be sprayed for extinguishing the fire.

Therefore, the fire extinguishing agent 220 does not need to be stored under pressure and can be sprayed out only by quickly pressurizing through the gas generating device 2 when in use, thereby solving the problem that the fire extinguishing equipment 200 cannot normally spray the fire extinguishing agent 220 due to pressure leakage of the existing pressure storage type fire extinguishing equipment, saving the maintenance cost of periodical pressurization and simultaneously saving a pressure gauge.

The sealed container 21 of the gas generating device 2 is of an integrated structure, is a sealed whole and is a complete part, and the structure of a sealing ring, a sealing glue, a sealing cover, a sealing bolt and the like is not provided, so that the gas generating device can be independently stored, the pressure leakage problem is avoided, and the driving medium 22 can be stably sealed in the sealed container 21 and cannot be leaked. The shape of the sealed container 21 is not limited, and for example, the cross section of the sealed container 21 may be circular, oval, rectangular, square, triangular, or the like. The sealed container 21 may be a metal container.

The gas generator 2 may spray more or less gas for a longer or shorter time, and may be selected according to the amount of the driving medium 22.

In addition, the existing non-pressure storage type fire extinguishing equipment is characterized in that the initiation device 3 is arranged in the gas generating device 2, and the gas is initiated to be sprayed out of the gas generating device 2 by adopting an electric initiation or thermal initiation mode. Because the gas generating device adopted by the existing non-pressure storage type fire extinguishing equipment is an initiating device, when the initiating device initiates the gas generating device, high temperature of hundreds of degrees centigrade is generated instantly. The gas can explode when meeting high temperature, so the gas extinguishing device can not be used, and the gas extinguishing device can only be suitable for dry powder extinguishing devices. In the starting device 100 provided by the scheme, the initiation device 3 is arranged outside the gas generation device 2, the gas generation device 2 is a non-explosive workpiece, and the gas generation device 2 is initiated to generate gas in a manner of releasing pressure of the sealing container 21 by opening the sealing container 21, so that the starting device not only can be suitable for a dry powder fire extinguishing device, but also can be suitable for a gas fire extinguishing device and a liquid fire extinguishing device, thereby greatly expanding the range of non-pressure storage type fire extinguishing equipment and solving the problem of pressure release for many years in the field of pressure storage type fire extinguishing equipment.

In addition, compare in current non-pressure storage formula dry powder fire extinguishing apparatus, starting drive 100 of this scheme of adoption can avoid the ignition to cause the improper condition that leads to the dry powder explosion to take place to the potential safety hazard that the explosion of fire extinguishing apparatus 200 self and cause has been avoided. Compared with the existing pressure storage type gas fire extinguishing equipment, the starting device 100 of the scheme can change the pressure storage type gas fire extinguishing equipment into non-pressure storage type gas fire extinguishing equipment, fundamentally solves the pressure leakage problem of the gas fire extinguishing equipment, and improves the fire extinguishing reliability of the gas fire extinguishing equipment.

Certainly, the starting device provided by the embodiment of the invention not only can be used for fire extinguishing equipment, but also can be widely applied to pressurized equipment (with pressurized containers) in various fields of national economy such as energy, traffic, metallurgy, electric power, communication and the like, and the conventional pressurized equipment can be converted into non-pressure storage equipment, so that the problem of pressure relief bothering the industry for many years is solved, and effective guarantee is provided for protecting national property and the safety of people.

When the starting device is used for other equipment, correspondingly, the nozzle 115 is used for ejecting the substances in other containers with pressure, and the driving medium 22 in the gas generating device 2 ejects the sealed container 21 and forms gas for driving the ejection of the substances in the containers of other equipment.

In one illustrative example, as shown in FIG. 1, the initiation device 3 comprises: a striker 31 and an initiator 32. Wherein, a striker 31 is provided corresponding to the sealed container 21 for piercing the sealed container 21 so that the sealed container 21 is opened. The initiator 32 is matched with at least one of the gas generating device 2 and the striker 31 and is used for driving at least one of the gas generating device 2 and the striker 31 to move towards the other so that the striker 31 punctures the sealed container 21.

In this example, the initiator device 3 includes a striker 31 and an initiator 32. The initiator 32 may be used to drive the movement of the striker 31 so that the striker 31 approaches the sealed container 21 and punctures the sealed container 21. Alternatively, the initiator 32 can also be used to drive the gas generating device 2 to move, so that the gas generating device 2 is close to the striker 31, and the striker 31 can pierce the sealed container 21. Alternatively, the initiator 32 can be used to drive the striker 31 and the gas generating device 2 to move simultaneously, so that the gas generating device 2 and the striker 31 approach each other until the striker 31 pierces the sealed container 21, which is beneficial to increase the initiation speed. As long as the striker 31 comes close to the hermetic container 21, the striker 31 can rapidly pierce the hermetic container 21 with the tip portion without generating sparks, and is safe in use and high in opening efficiency.

Of course, the inducing means 3 is not limited to the above-described ones. For example, the initiating device can also comprise a cutter and a motor, wherein the motor drives the cutter to move, so that the cutter cuts the sealed container and the sealed container is opened; alternatively, the initiating device may comprise a small power drill by which the sealed container is opened.

In one illustrative example, as shown in fig. 1, a gas generating device 2 is located within a housing 1. The striker 31 is fixed in the shell 1, and the initiator 32 is matched with the gas generating device 2 and is used for driving the gas generating device 2 to move towards the direction close to the striker 31.

The gas generating device 2 is positioned in the shell 1 and can be protected by the shell 1, so that the fire extinguishing apparatus 200 is prevented from being opened by mistake due to the fact that the gas generating device 2 is opened by mistake by other structures outside the shell 1, and property loss or personal injury is caused.

In one illustrative example, as shown in fig. 1, the housing 1 includes a first housing 11 and a support base 12, the support base 12 being in contact engagement with the gas generating device 2. The supporting seat 12 and the gas generating device 2 are both in sliding fit with the first shell 11. The support base 12 is located in the first housing 11 and encloses a sealed cavity 13 with the first housing 11. One end of the initiator 32 is located in the sealed cavity 13 and is used for increasing the air pressure of the sealed cavity 13 so as to drive the supporting seat 12 to drive the gas generating device 2 to move towards the direction close to the striker 31. The other end of the initiator 32 extends through the first housing 11 to the outside of the first housing 11.

With a plurality of parts such as first shell 11, supporting seat 12 of casing 1 split, both be favorable to reducing the processing degree of difficulty of each part, also be convenient for rationally select the material of each part as required, also be convenient for the assembly of 1 inner part of casing to optimize starting device 100's structure, reduce starting device 100's the assembly degree of difficulty.

Further, the first housing 11 and the support base 12 enclose a sealed cavity 13. The initiator 32 is specifically used for increasing the air pressure of the sealed cavity 13, so that the increased air pressure is used for driving the supporting seat 12 to move, and the supporting seat 12 is in contact fit with the gas generating device 2, so that the supporting seat 12 can drive the gas generating device 2 to move, the driving function of the initiator 32 on the gas generating device 2 is realized, and the conception is ingenious. The supporting seat 12 is used for driving the gas generating device 2 to move, so that the gas generating device 2 is isolated from the sealed cavity 13, the temperature change in the sealed cavity 13 can be prevented from causing the temperature change of the sealed container 21 to influence the state of the driving device in the sealed container 21, and the stability of the gas generating device 2 is improved.

Further, as shown in fig. 1, the supporting seat 12 is provided with an avoiding groove 122, and the avoiding groove 122 can avoid the resistor 321 of the electrical initiator, so as to prevent the resistor 321 from being damaged in the assembling process due to insufficient space of the sealing cavity 13.

In one illustrative example, as shown in fig. 2, the sealed container 21 includes a head portion 211 and a body portion 212. The head 211 is provided corresponding to the striker 31. The supporting seat 12 is provided with a limiting groove 121, and one end of the body 212 far away from the head 211 is in concave-convex fit with the limiting groove 121.

The head 211 of the sealed container 21 is disposed corresponding to the striker 31, and can be pierced by the striker 31 to open the sealed container 21. The limiting groove 121 of the supporting seat 12 can limit the sealed container 21, and increase the contact area between the supporting seat 12 and the sealed container 21, thereby improving the stability of the gas generating device 2 in the movement process and reducing the probability of the gas generating device 2 inclining, shifting and the like.

In one illustrative example, the initiator 32 comprises an electrical initiator 32. As shown in fig. 1, the electrical initiator 32 includes a resistor 321 and a connecting wire 322 connected to the resistor 321, the resistor 321 is located in the sealed chamber 13, and the connecting wire 322 extends through the housing 1 to the outside of the housing 1.

In another illustrative example (not shown), the initiator 32 comprises a thermal initiator 32.

In yet another illustrative example (not shown), the initiator 32 includes both the electrical initiator 32 described above and the thermal initiator 32 described above.

The initiator 32 can be an electric initiator 32, and the resistor 321 heats up by connecting with a power supply, so that the air pressure of the sealed cavity 13 is increased, and further the support seat 12 and the gas generating device 2 are initiated to move, so that the striker 31 opens the sealed container 21. The electrical initiator 32 has three indexes of starting current, safety current and resistance value. These three indices satisfy the following relationships: the safe current is smaller than the starting current, and the resistor 321 is not heated when being electrified for five minutes in the safe current index; when the current reaches or exceeds the starting current, the resistor 321 heats; the smaller the resistance value is, the larger the current is, and on the contrary, the larger the resistance value is, the smaller the current is; the safe current, the starting current and the resistance value can be set according to requirements.

The initiator 32 may also be a thermal initiator 32, and the thermal initiator 32 includes a thermosensitive element, which is sensitive to the external temperature, and when a fire occurs, the thermosensitive element can sense the rise of the external temperature to generate heat, so that the air pressure in the sealed cavity 13 rises, and the movement of the support seat 12 and the sealed container 21 is automatically initiated, and the striker 31 opens the sealed container 21.

Of course, the initiator 32 may also include both an electrical initiator 32 and a thermal initiator 32, so that the fire extinguishing apparatus can be activated either manually or automatically, effectively preventing the risk of the fire extinguishing apparatus failing to be activated.

In one illustrative example, as shown in fig. 1, the first housing 11 includes: a housing body 111 and a first cover 112. Wherein, the shell body 111 is provided with a first mounting opening 1111. At least one part of the gas generating device 2 is located in the shell body 111 and is in sliding fit with the shell body 111. Support base 12 is mounted at first mounting opening 1111 and is in sliding engagement with housing 111. The first cover 112 is connected to the housing 111, and a space between the first cover 112 and the support base 12 forms the sealed chamber 13.

With a plurality of parts such as shell body 111, first lid 112 of first shell 11 split, both be favorable to reducing the processing degree of difficulty of each part, also be convenient for rationally select the material of each part as required, also be convenient for the assembly of casing 1 inner part to optimize starting drive 100's structure, reduce starting drive 100's the assembly degree of difficulty. During the assembly process, the gas generating device 2 can be installed into the housing 111 through the first installation opening 1111, then the support base 12 is installed at the first installation opening 1111, and then the first cover 112 is covered.

The first cover 112 and the shell 111 can be fixed through threaded connection, so that the connection strength is high, and the assembly is convenient and rapid.

In one illustrative example, as shown in fig. 1, the housing body 111 has a cylindrical structure. The first mounting port 1111 is disposed at one end of the housing 111, and the second mounting port 1112 is disposed at the other end of the housing 111. The gas generating device 2 is located in the shell body 111. The first housing 11 also includes a seal assembly 113, the seal assembly 113 sealing the second mounting port 1112. The striker 31 is positioned between the sealing assembly 113 and the gas generating device 2. The seal assembly 113 is provided with a gas passage 1135. The gas passing passage 1135 communicates with the inner space of the housing body 111, and is used for conveying the gas sprayed from the sealed container 21, specifically, for conveying the gas for driving the fire extinguishing agent 220 to the fire extinguishing agent storage container 210.

The shell 111 is a cylindrical structure, and has two open ends, so that the two ends of the shell 111 form a first mounting opening 1111 and a second mounting opening 1112 respectively, and the shell is simple in structure and convenient to machine and form. The gas generating device 2 is completely arranged in the shell body 111, and two ends of the shell body 111 are respectively sealed by the supporting seat 12 and the sealing component 113, so that the gas generating device 2 can be well protected, and the fire extinguishing apparatus 200 can be effectively prevented from being opened by mistake due to the fact that the gas generating device 2 is opened by mistake. Correspondingly, the sealing assembly 113 is provided with the gas passage 1135, so that the gas sprayed from the gas generating device 2 can be sprayed out of the housing 1 through the gas passage 1135 and further delivered into the fire extinguishing agent storage container 210, so that the gas pressure in the fire extinguishing agent storage container 210 is rapidly increased to drive the fire extinguishing agent 220 to spray out.

The housing 111 may have a cylindrical structure. Accordingly, the cross-section of the sealed container 21 may be circular. Thus, there is no edge or corner between sealed container 21 and housing 111, which is beneficial to reduce the probability of jamming between sealed container 21 and housing 111, thereby improving the reliability of starting device 100. The striker 31 may be fixed within the housing 111 by a bracket.

Of course, when the starting device is used in other equipment, the gas passing channel is used for conveying gas formed by the driving medium (namely, gas sprayed out of the sealed container) to the container body of other equipment.

In one illustrative example, as shown in fig. 1, the seal assembly 113 includes a second cap 1131, a sealing plug 1132 and a first sealing diaphragm 1133. The second cover 1131 is fixedly connected to the housing 111. The second cover 1131 is provided with a first relief notch 1134. The sealing plug 1132 is located inside the housing body 111 and is in interference fit with the housing body 111. The air passage 1135 is disposed on the sealing plug 1132, and is disposed corresponding to the first avoiding notch 1134. The striker 31 is located between the gas generating device 2 and the sealing plug 1132. The first sealing diaphragm 1133 is sandwiched between the end face of the housing 111 and the second cover 1131.

The sealing plug 1132 is in interference fit with the housing body 111, which improves the sealing reliability. The sealing plug 1132 is provided with a gas passage 1135 to ensure that the gas ejected from the gas generating device 2 can be ejected out of the housing 1. The first sealing membrane 1133 blocks the gas passing channel 1135, so as to ensure that the gas passing channel 1135 is not communicated with the fire extinguishing agent storage container 210 when there is no fire. When a fire occurs and the gas generating device 2 is opened, the gas passing through the gas passage 1135 can burst the first sealing membrane 1133 and further enter the fire extinguishing agent storage container 210, so that the gas pressure in the fire extinguishing agent storage container 210 is rapidly increased to drive the fire extinguishing agent 220 to be sprayed out. The second cover 1131 fixes the sealing plug 1132 and the first sealing diaphragm 1133, so as to ensure the stability of the sealing plug 1132 and the first sealing diaphragm 1133.

The first sealing membrane 1133 may be made of an aluminum membrane or other materials. Second lid 1131 can be with shell 111 threaded connection, and joint strength is high, and convenient assembling is swift. The sealing plug 1132 may be a silicone plug or a rubber plug. The striker 31 is fixedly connected to the sealing plug 1132, and may specifically be fixedly connected by interference fit, plastic-coated molding, or other methods.

In one illustrative example, the drive medium 22 is a gaseous medium.

The driving medium 22, which may be a gaseous medium, is stored in the sealed container 21 and is rapidly ejected when the sealed container 21 is opened. The driving medium 22 may be nitrogen, argon, carbon dioxide, air, etc., and the pressure level is higher than 1.2 MPa.

In another illustrative example, the driving medium 22 is a liquid medium.

The driving medium 22 may also be a liquid medium, and may be enclosed in the sealed container 21 in a liquid form, and may be vaporized into a gas to be sprayed after the sealed container 21 is opened, such as liquid carbon dioxide, liquid propane, etc. In other words, the driving medium 22 is a liquid to gas medium.

Alternatively, the driving medium 22 may be a solid medium, which is enclosed in the sealed container 21 in a solid state and sublimated to be sprayed with gas after the sealed container 21 is opened, such as solid carbon dioxide (dry ice). In other words, the driving medium 22 is a medium from solid to gas, and is directly decompressed into gas through the sealed container, rather than being burned or exploded to generate gas, so that the gas generating device 2 is still a non-explosive work.

Alternatively, the driving medium comprises any combination of gaseous, liquid and solid media. In other words, the driving medium may also comprise a gaseous medium and a liquid medium. Or the drive medium may also comprise a gaseous medium and a solid medium. Or the drive medium may also comprise a liquid medium and a solid medium. Alternatively, the driving medium may comprise a gaseous medium, a liquid medium and a solid medium. The medium in two different states or the medium in three different states sealed in the sealed container do not react with each other and can be ejected in a gaseous state after the sealed container is opened.

In one illustrative example, the striker 31 has a rockwell hardness greater than or equal to HR 60.

Setting the hardness of the striker 31 within the above range ensures that the striker 31 can pierce the sealed container 21 quickly and efficiently.

In one illustrative example, the diameter of the tip of the striker 31 is between 2mm and 3 mm.

The diameter of the needle tip of the striker 31 is limited to 2mm to 3mm, which ensures that the gas can be rapidly ejected after the sealed container 21 is punctured.

Another embodiment of the present invention, as shown in fig. 4, provides an initiator device 100'. The starting apparatus 100' includes: a shell 1 ', a gas production device 2 ' and an initiation device 3 '.

In particular, the housing 1 'is provided with at least one spout 115'. The gas generating device 2 'comprises an integrated sealed container 21' and a driving medium 22 'sealed in the sealed container 21'. The sealed container 21 'is connected to the housing 1'. The initiation device 3 'is positioned outside the gas production device 2'.

The difference from the first embodiment is that:

the initiator assembly 3 ' includes a striker 31 ' and an initiator 32 '. The striker 31 ' is provided in correspondence with the sealed container 21 ' for piercing the sealed container 21 ' to eject the driving medium 22 ' out of the sealed container 21 ' and form a gas. The initiator 32 'is coupled to the striker 31' for driving the striker 31 'in a direction approaching the sealed container 21' so that the striker 31 'pierces the sealed container 21'.

The initiator 32 'is used to drive the movement of the striker 31'. The striker 31 'can rapidly pierce the hermetic container 21' with the tip portion thereof without generating sparks, and is safe in use and high in opening efficiency.

In one illustrative example, further, as shown in fig. 4, the striker 31 'is located within the housing 1' and encloses a sealed chamber 1111 'with the housing 1'. One end of the initiator 32 ' is located within the sealed chamber 1111 ' for pneumatically elevating the sealed chamber 1111 ' to drive the striker 31 ' in a direction approaching the sealed container 21 '. The other end of the initiator 32 ' extends through the housing 1 ' and out of the housing 1 '.

In this embodiment, the initiator 32 ' is specifically configured to increase the air pressure in the sealed chamber 1111 ', so as to drive the movement of the striker 31 ' by the increased air pressure, and the concept is ingenious.

In one illustrative example, further, as shown in fig. 4, the striker 31' includes: a sliding portion 311 'and a needling portion 312'. The sliding portion 311 'and the housing 1' enclose a sealed cavity 1111 'and are in sliding fit with the housing 1'. The needle-piercing portion 312 ' is connected to the sliding portion 311 ', and the needle-piercing portion 312 ' is disposed toward the hermetic container 21 ' for piercing the hermetic container 21 '.

The striker 31 ' includes a sliding portion 311 ' and a needle-punching portion 312 ', and the sliding portion 311 ' is slidably engaged with the housing 1 ' to ensure that the striker 31 ' can smoothly move relative to the housing 1 '. The needle-piercing portion 312 ' is provided corresponding to the sealed container 21 ' for performing the piercing function of the striker 31 '.

The outer side wall of the sliding part 311 'may be a cylindrical structure, so that there is no edge, corner, etc. between the sliding part 311' and the housing 1 ', which is beneficial to reducing the probability of the jamming between the striker 31' and the housing 1 ', thereby improving the reliability of the starting apparatus 100'. The needle-punched portion 312' may include a conical structure having both a high strength and a pointed portion.

In one illustrative example, further, as shown in fig. 4, the sliding portion 311 ' includes an end plate 3111 ' and a side wall plate 3112 '. The side shroud 3112 ' is connected to the edge of the end plate 3111 ' and encloses a recess with the end plate 3111 ' that is open at one end. The housing 1 ' seals the open end of the recess and encloses a sealed chamber 1111 ' with the slide 311 '. The needled portion 312 ' is connected to the face of the end plate 3111 ' facing away from the side shroud 3112 '.

In the scheme, the sliding part 311 'adopts a hollow structure, and the sliding part 311' and the shell 1 'are utilized to enclose the sealed cavity 1111', so that the volume of the sealed cavity 1111 'is reduced, and the air pressure rising speed of the sealed cavity 1111' is improved; on the other hand, the mass of the striker 31 ' is reduced, which is advantageous for reducing the air pressure value for pushing the striker 31 ' to move, and thus increasing the triggering speed of the triggering device 3 '.

Further, the end plate 3111 ', the side wall plate 3112 ' and the needle punching portion 312 ' are of an integral structure, that is, the striker 31 ' is integrally formed, so that the strength of the striker 31 ' is high, and the assembly efficiency is improved.

In one illustrative example, further, as shown in fig. 4, the housing 1 ' includes an outer shell 11 ' and a sealing plug 12 '. A first mounting cavity 111 'is provided in the housing 11'. The sealing plug 12 ' and at least a portion of the striker 31 ' are located within the first mounting cavity 111 '. The sliding portion 311 'is slidably fitted with the housing 11'. The sealing plug 12 ' and the sliding part 311 ' enclose a sealing chamber 1111 '.

The shell 1 'is split into the shell 11', the sealing plug 12 'and other parts, so that the processing difficulty of each part is reduced, the materials of each part can be reasonably selected as required, and the assembly of the parts in the shell 1' is facilitated, so that the structure of the starting device 100 'is optimized, and the assembly difficulty of the starting device 100' is reduced. The sealing plug 12 ' is used for sealing the groove of the sliding part 311 ', which is beneficial to improving the sealing reliability of the sealing cavity 1111 '. Wherein, the housing 11' may be a metal housing. The sealing plug 12' may be a rubber plug or a silicone plug.

In an illustrative example, further, the striker 31 'may be made of a metal member having a high hardness to facilitate quick penetration of the sealed container 21'. At least one sealing ring is sleeved between the sliding part 311 ' and the housing 11 ' to further improve the sealing reliability of the sealing cavity 1111 '. The side wall plate 3112 ' of the sliding portion 311 ' is provided with at least one seal groove 3113 ' for mounting a seal ring, as shown in fig. 4. Wherein the housing 11 'is provided with a through hole through which the initiator 32' extends out of the housing 1 'through the sealing plug 12'.

In an illustrative example, further, as shown in fig. 4, a mounting hole 131 ' and at least one air passing passage 132 ' are provided in the housing 1 '. The sealed container 21 ' includes a head portion 211 ' and a body portion 212 ', as shown in fig. 5. The head 211 ' is installed in the installation hole 131 ', and the head 211 ' is provided corresponding to the striker 31 ' to eject gas formed by the driving medium 22 '. The gas passing passage 132 'communicates with the installation hole 131', and one end of the gas passing passage 132 'penetrates the housing 1' for delivering the gas formed by the driving medium 22 'to the fire extinguishing agent storage container 210'.

The housing 1 ' is provided therein with a mounting hole 131 ' and a gas passing passage 132 '. The mounting hole 131 'is used to mount the head portion 211' of the hermetic container 21 ', and the body portion 212' of the hermetic container 21 'can be inserted into the fire extinguishing agent storage container 210'. The air passage 132 'is used to supply air to the fire extinguishing agent storage container 210', and the fire extinguishing agent storage container 210 'is rapidly pressurized to spray the fire extinguishing agent 220'. The gas passing channel 132 ' is communicated with the mounting hole 131 ' to ensure that gas sprayed out of the head part 211 ' of the sealed container 21 ' can enter the gas passing channel 132 '; one end of the air passing channel 132 'penetrates the housing 1' to ensure that the air passing channel 132 'can communicate with the fire extinguishing agent storage container 210' after the housing 1 'is assembled with the fire extinguishing agent storage container 210'.

In one illustrative example, further, as shown in fig. 4, the housing 1 ' includes a shell 11 ' and a support base 13 '. A second mounting cavity 112 'is provided in the housing 11'. The support base 13 'is mounted in the second mounting cavity 112'. The mounting hole 131 ' and the air passage 132 ' are provided on the support base 13 '.

The shell 1 'is split into the shell 11', the supporting seat 13 'and other parts, so that the processing difficulty of each part is reduced, the materials of each part can be reasonably selected as required, and the assembly of the parts in the shell 1' is facilitated, so that the structure of the starting device 100 'is optimized, and the assembly difficulty of the starting device 100' is reduced.

In an exemplary embodiment, the supporting base 13 'is further provided with a relief hole 133', and the relief hole 133 'is communicated with the mounting hole 131'. The needle-punched portion 312 'is inserted into the escape hole 133', as shown in fig. 4. The cross-sectional area of the escape hole 133 'is larger than that of the mounting hole 131'. The air passage 132 'penetrates through both ends of the support base 13' along the axial direction of the avoiding hole 133 ', and the air passage 132' penetrates through the hole wall of the avoiding hole 133 'along the radial direction of the avoiding hole 133'.

In this embodiment, the provision of the avoiding hole 133 ' reduces the distance between the striker 31 ' and the sealed container 21 ', so that the striker 31 ' can rapidly pierce the sealed container 21 '. Meanwhile, the avoiding hole 133 ' is relatively thick, and the mounting hole 131 ' is relatively thin, so that the air passage 132 ' can penetrate through the hole wall of the avoiding hole 133 ' along the radial direction of the avoiding hole 133 ', the hole wall of the avoiding hole 133 ' is not a complete annular structure in the circumferential direction, and the hole wall of the mounting hole 131 ' can be a complete annular structure in the circumferential direction. In this way, the mounting hole 131 'and the head 211' of the hermetic container 21 'can have a larger contact area to improve the fixing reliability of the hermetic container 21'; and the gas jetted from the head 211 'in the mounting hole 131' can more easily enter the gas passing channel 132 ', thereby increasing the initiation speed of the initiation device 3'.

Further, the cross-section of the avoiding hole 133' is circular. The mounting hole 131' has a circular cross-section. The avoiding hole 133 'is coaxially disposed with the mounting hole 131', and the radius of the avoiding hole 133 'is greater than that of the mounting hole 131'.

Furthermore, the supporting seat 13 'is in threaded connection with the shell 11', so that the connection is reliable and the assembly is convenient. The head 211 ' of the sealed container 21 ' is in threaded connection with the supporting seat 13 ', so that the connection is reliable and the assembly is convenient.

Further, the number of the air passing channels 132 'is plural, and the plural air passing channels 132' are spaced along the circumference of the support base 13 ', so that the air can be rapidly and uniformly introduced into the fire extinguishing agent storage container 210'.

In one illustrative example, further, as shown in FIG. 4, the cross-sectional area of second mounting cavity 112 'is greater than the cross-sectional area of first mounting cavity 111', such that first mounting cavity 111 'and second mounting cavity 112' form a stepped bore configuration. The end face of the support seat 13 ' close to the first mounting cavity 111 ' abuts against the end face of the second mounting cavity 112 '. The end surface of the supporting seat 13 ' close to the first mounting cavity 111 ' protrudes from the inner side surface of the first mounting cavity 111 ' to form a stopping surface 134 ' for stopping the striker 31 ', as shown in fig. 4.

During assembly, the sealing plug 12 ' may be first installed into the first installation cavity 111 ' through the second installation cavity 112 ', then the striker 31 ' is installed into the first installation cavity 111 ' through the second installation cavity 112 ', then the supporting seat 13 ' is installed into the second installation cavity 112 ' until the supporting seat 13 ' abuts against the step of the stepped hole, and then the head 211 ' of the sealed container 21 ' is installed into the installation hole 131 ' of the supporting seat 13 '. Thus, the assembly process of the starting apparatus 100' is simple and convenient.

In addition, when the striker 31 'moves to abut against the support seat 13' in the use process, the striker is stopped by the support seat 13 'and cannot move continuously, so that the sliding stroke of the striker 31' is limited, and the phenomenon that the sealed container 21 'is excessively deformed and falls off due to the overlarge movement amplitude of the striker 31' is avoided.

Further, the piercing portion 312 'of the striker 31' is provided with a transition passage 3121 'communicating with the air passage 132', as shown in fig. 4. Thus, the gas in the sealed container 21 'can also enter the gas passing channel 132' through the transition channel 3121 ', thereby further increasing the initiation speed of the initiation device 3'. In addition, this may further reduce the mass of the striker 31 'and further reduce the requirements for the initiator 32'.

In one illustrative example, further, as shown in fig. 4, the housing 1 'is provided with at least one ejection passage 116', and the ejection passage 116 'communicates with the ejection port 115'. The activation device 100 ' further comprises a sealing valve 4 ', the sealing valve 4 ' being adapted to disconnect the ejection channel 116 ' from the nozzle opening 115 ', the sealing valve 4 ' being arranged to conduct the ejection channel 116 ' to the nozzle opening 115 ' under the impact of a fluid, such as fire suppressant 220 '.

The spouting passage 116 'is provided to be capable of communicating with the fire extinguishing agent storage container 210'. The sealing valve 4 'ensures that the spraying channel 116' is disconnected from the spraying opening 115 'when the fire extinguishing apparatus is not in use, thereby preventing the fire extinguishing agent 220' from spraying out to cause property loss or personal injury. In case of fire, when the trigger device 3 'opens the sealed container 21', the fire extinguishing agent in the fire extinguishing agent storage container 210 'flows to the discharge passage 116' under the action of air pressure, and further, the sealed valve 4 'is opened, and the fire is discharged from the discharge opening 115'. Of course, when the starting device 100 'is used in other apparatuses, the ejection channel 116' is provided to be able to communicate with the container body of the other apparatuses.

Wherein, the sealing valve 4 'can adopt a metal sealing plug, and is in interference fit with the shell 1'.

Further, at least one sealing ring is sleeved between the sealing valve 4 ' and the housing 1 ' to further improve the sealing reliability of the sealing valve 4 '. The outer side wall of the sealing valve 4 'is provided with a sealing groove 3113' for mounting a sealing ring.

Further, the number of the ejection channels 116 'may be equal to and correspond to the number of the ejection ports 115', and the number of the sealing valves 4 'may be equal to and correspond to the number of the ejection channels 116', so as to ensure that each ejection channel 116 'and each ejection port 115' can be in a disconnected state in the absence of fire.

The number of the ejection channels 116 'may also be different from the number of the nozzles 115', for example, the ejection channels 116 'may have a three-way structure, a four-way structure, or the like, and one ejection channel 116' may communicate with three or four nozzles 115 ', which is beneficial to reducing the number of the sealing valves 4', thereby simplifying the product structure and reducing the product cost.

In one illustrative example, further, as shown in fig. 4, the starting apparatus 100' further includes: the siphon tube 5 ' is fixedly connected to the housing 1 ' and communicates with the spouting passage 116 '.

When the starting apparatus 100 'is completely assembled with the fire extinguishing agent layer storage container 210', the siphon tube 5 'is inserted into the fire extinguishing agent storage container 210'. The siphon tube 5 'can suck the fire extinguishing agent 220' in the fire extinguishing agent storage container 210 'into the spouting passage 116' by using the siphon principle, so that the fire extinguishing agent 220 'continuously enters the spouting passage 116', thereby improving the fire extinguishing efficiency. Furthermore, the siphon 5 ' is a plastic pipe, and the siphon 5 ' is in threaded connection with the shell 1 '.

Of course, for small fire-extinguishing systems, the amount of extinguishing agent 220 'is relatively small, and the siphon 5' can also be eliminated. Alternatively, in the case where the fire extinguishing agent storage container 210 ' is up and the starting device 100 ' is down, the fire extinguishing agent 220 ' may automatically flow toward the spouting passage 116 ' by gravity, and in this case, the siphon tube 5 ' may be eliminated.

In an exemplary embodiment, as shown in fig. 4, a third installation cavity 113 'and a bypass cavity 117' communicating with the third installation cavity 113 'are further provided in the housing 1'. The sealing valve 4 'is installed in the third installation chamber 113' to interrupt the communication between the spouting passage 116 'and the spouting port 115' and is provided to be movable into the escaping chamber 117 'under the impact of the fluid (e.g., the fire extinguishing agent 220') to communicate the spouting passage 116 'and the spouting port 115'.

Thus, the sealing valve 4 'is still located in the housing 1' after being impacted by the fire extinguishing agent 220 ', and the sealing valve 4' can be prevented from bursting out to cause property loss or cover on human body.

In one illustrative example, further, as shown in fig. 4, the starting apparatus 100' further includes: the elastic member 6 ' is disposed in the housing 1 ' and abuts against the sealing valve 4 ' for restricting the sealing valve 4 ' from moving to the avoiding chamber 117 '.

The elastic piece 6 'can exert an acting force on the sealing valve 4', so that the position stability of the sealing valve 4 'is improved, and the fire extinguishing agent 220' is prevented from being sprayed out by mistake in the absence of fire to cause property loss or personal injury.

Wherein, the elastic member 6' can be a compression spring, a spring plate, a silica gel ball and other structures.

In one illustrative example, further, as shown in fig. 4, the housing 1 ' includes a sealing cover 14 ' and a shell 11 '. The housing 11 'is provided with a fourth mounting cavity 114' opened at both ends. One end of the fourth mounting cavity 114 ' is communicated with the third mounting cavity 113 ', and the sealing cover 14 ' is used for covering one end of the fourth mounting cavity 114 ' far away from the third mounting cavity 113 '.

The shell 1 'is split into the shell 11', the sealing cover 14 'and other parts, so that the processing difficulty of each part is reduced, the materials of each part can be reasonably selected as required, and the assembly of the parts in the shell 1' is facilitated, so that the structure of the starting device 100 'is optimized, and the assembly difficulty of the starting device 100' is reduced.

Specifically, in the assembling process, the sealing valve 4 'may be installed in the third installation cavity 113' through the fourth installation cavity 114 ', the elastic member 6' is then installed in the housing 11 ', the elastic member 6' abuts against the sealing valve 4 ', and then the sealing cover 14' is covered.

Further, as shown in fig. 4, the sealing cover 14 'is provided with a stopper groove 141', and a portion of the elastic member 6 'is stopped in the stopper groove 141'.

The limiting groove 141 'can limit the elastic piece 6' and prevent the elastic piece 6 'from inclining, shifting and the like, thereby improving the use reliability of the elastic piece 6'.

In an illustrative example, further, as shown in fig. 4, the end of the sealing valve 4 ' facing the sealing cover 14 ' is also provided with a stopper groove 42 '. One end of the elastic member 6 ' can be inserted into the limiting groove 42 ', which is beneficial to further preventing the elastic member 6 ' from tilting, shifting and the like, and ensuring good matching of the elastic member 6 ' and the sealing valve 4 '.

Further, as shown in fig. 4, the sealing valve 4 ' is further provided with a limiting boss 41 ' at an end thereof facing the sealing cover 14 '. The cross-sectional area of the limiting boss 41 ' is larger than that of the third mounting cavity 113 ', so that the sealing valve 4 ' can be prevented from being stuck in the third mounting cavity 113 ' to influence the normal ejection of the fire extinguishing agent 220 '.

As shown in fig. 3, an embodiment of the present invention also provides a fire extinguishing apparatus 200 including: a fire extinguishing agent storage container 210 and an activation device 100 as in the first embodiment described above.

Wherein the fire extinguishing agent storage container 210 is filled with the fire extinguishing agent 220. The shell 1 of the starting device 100 is connected with the fire extinguishing agent storage container 210, and the gas generating device 2 of the starting device 100 is used for delivering gas for driving the fire extinguishing agent 220 to spray into the fire extinguishing agent storage container 210.

The third cover 2104 is provided at the second opening 2110, and the third cover 2104 is provided with fire suppressant spray 2106.

The fire extinguishing agent storage container 210 is divided into a plurality of components such as the second housing 2102 and the third cover 2104, so that the structure of each component is simplified, and the processing difficulty of each component is reduced. The second housing 2102 is provided with a first opening 2108 and a second opening 2110, wherein the first opening 2108 is adapted to the activation device 100 to ensure proper coupling of the activation device 100 to the second housing 2102. The second opening 2110 mates with the third cover 2104 to ensure proper assembly of the third cover 2104 with the second housing 2102. The placement of the fire suppression agent port 2106 on the third cover 2104 prevents the second housing 2102 from being vented, which contributes to the strength of the second housing 2102.

The first opening 2108 may be specifically adapted to the first cover 112 of the starting apparatus 100, so that the first cover 112 and the second housing 2102 may be fixed by a threaded connection, and the connection strength is high, and the assembly is convenient and fast.
