The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
It will be understood that, as used herein, the terms "first," "second," and the like may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another.
It is to be understood that "connection" in the following embodiments is to be understood as "electrical connection", "communication connection", and the like if the connected circuits, modules, units, and the like have communication of electrical signals or data with each other.
As used herein, the singular forms "a", "an" and "the" may include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises/comprising," "includes" or "including," etc., specify the presence of stated features, integers, steps, operations, components, parts, or combinations thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, components, parts, or combinations thereof. Also, as used in this specification, the term "and/or" includes any and all combinations of the associated listed items.
As mentioned in the background art, the feedback device of the fire extinguishing apparatus in the prior art is insensitive to response and cannot accurately feed back the starting state of the fire extinguishing apparatus, and the applicant researches and discovers that the problem is caused by the fact that a mechanical feedback device is adopted in many existing fire extinguishing apparatuses, but the mechanical feedback device often fails due to mechanical damage, passivation or aging after long-term operation, so that a signal about whether the fire extinguishing apparatus is operated cannot be accurately fed back, normal operation of a system cannot be guaranteed, and adverse effects on human lives and properties are caused.
Based on the above reason, this experimental novel embodiment provides a feedback device of fire extinguishing apparatus, includes: a case 1, a heat-sensitive wire 3, a heat-sensitive element 5, and a lead wire 7. The housing 1 serves to protect the components inside the housing. In an environment such as a factory workshop, the feedback device is very susceptible to the influence of the workshop, and therefore the housing 1 is provided to protect the components of the feedback device. The openings are formed in the two ends of the feedback device, other components of the feedback device can be conveniently placed into the shell 1, and when the other components of the feedback device are replaced or maintained, the components inside the shell 1 can be replaced or detected through the two openings of the shell 1.
The feedback device further comprises a heat-sensitive wire 3, wherein a first end of the heat-sensitive wire 3 is connected with a sensitive object of the fire extinguishing equipment, and a second end of the heat-sensitive wire 3 extends into the shell 1 and is used for changing the temperature of the heat-sensitive wire according to the temperature of the sensitive object. The thermo-sensitive wire 3 is a temperature-sensitive lead wire whose surface is covered with a thermo-sensitive material, and when the temperature rises to the threshold temperature of the thermo-sensitive wire 3, the thermo-sensitive wire 3 will burn. Wherein the sensitive objects are parts of the fire extinguishing apparatus which are increased in temperature after the fire extinguishing apparatus is started to extinguish a fire, so that the temperature of the parts reflects whether the fire extinguishing apparatus has been started to extinguish the fire. The heat-sensitive wire 3 is connected to these components, and when their temperature is sufficiently high, the heat-sensitive wire 3 starts to burn, so the state of the heat-sensitive wire 3 may also reflect whether the fire extinguishing apparatus has started extinguishing a fire. Taking an aerosol type fire extinguishing apparatus as an example, the aerosol type fire extinguishing apparatus is internally provided with a cavity for containing an aerosol, and when a fire occurs, the aerosol is initiated to generate an oxidation-reduction combustion reaction in the cavity by a thermal starting or electric starting mode to generate condensed aerosol for extinguishing the fire. When the oxidation-reduction combustion reaction of the aerosol occurs, the temperature of the cavity is increased, the thermosensitive wire 3 is connected to the cavity, and if the thermosensitive wire 3 is burnt, the aerosol type fire extinguishing apparatus is operated.
The feedback device further comprises a thermosensitive element 5, and the thermosensitive element 5 is placed inside the shell 1 and used for sensing the temperature of the thermosensitive wire 3. A heat-sensitive element is an element whose characteristics change when a temperature change is sensed. The combustion of the heat-sensitive wire 3 reflects that the fire extinguishing equipment has started to extinguish fire, and the combustion of the heat-sensitive wire 3 also causes the temperature of the inner space of the shell 1 to rise, because the part of the heat-sensitive wire 3 and the heat-sensitive element 5 are both positioned in the inner space of the shell 1, and the heat-sensitive element 5 can sense the temperature change of the heat-sensitive wire 3 and change the characteristics thereof accordingly. Therefore, the characteristics of the heat-sensitive element 5 can also reflect whether the fire extinguishing apparatus is activated to extinguish a fire.
The feedback device also comprises a lead 7, wherein the lead 7 is connected to two ends of the heat-sensitive element 5 and penetrates through the shell 1 to be connected with a controller of the fire extinguishing equipment, so that the controller can judge whether the fire extinguishing equipment starts to extinguish fire according to the characteristics of the heat-sensitive element. Because the controller of the fire extinguishing apparatus cannot directly judge whether the heat-sensitive wire 3 is burnt, the burning of the heat-sensitive wire 3 needs to be converted into a signal which can be detected by the controller, such as an electric signal, and the like, the wire 7 connects the heat-sensitive element 5 with the controller, the characteristic of the heat-sensitive element 5 is transmitted into the controller in the way of the electric signal, and the controller can know whether the fire extinguishing apparatus is started to extinguish fire according to the characteristic of the heat-sensitive element 5.
The utility model provides a feedback device of fire extinguishing equipment based on an embodiment of the utility model. The part of the thermosensitive wire 3 and the thermosensitive element 5 are in the same shell 1, when a fire breaks out, the fire extinguishing equipment starts to extinguish the fire, the temperature of a sensitive object in the fire extinguishing equipment rises due to the fire extinguishing, and the temperature of the thermosensitive wire 3 also rises along with the temperature. The temperature of the thermosensitive wire 3 rises to the threshold temperature and then starts to burn, the thermosensitive element 5 senses the burning of the thermosensitive wire, the characteristic of the thermosensitive element 5 is changed, and a controller of the fire extinguishing equipment can know whether the fire extinguishing equipment is started or not according to the characteristic of the thermosensitive element 5. The feedback device adopting the structure has high transmission speed and improves the reaction speed because the transmitted signal is an electric signal.
Optionally, in one embodiment, the housing is open at one end. The second end of the thermosensitive wire penetrates through the opening of the shell and extends into the shell; the lead is connected with the controller of the fire extinguishing equipment through the opening of the shell. It can be understood that the opening is arranged on the shell, so that a thermosensitive wire, a conducting wire, a thermosensitive element and the like can be conveniently placed in the shell, and the installation and the replacement are also convenient.
Optionally, referring to fig. 1, in one embodiment, the two ends of the housing are open; the second end of the thermosensitive wire penetrates through the opening at one end of the shell and extends into the shell; the lead is connected with the controller of the fire extinguishing equipment through the opening at the other end of the shell. The lead wire 7 and the thermosensitive wire 3 pass through different openings of the shell 1, so that the damage of flame generated by the combustion of the thermosensitive wire 3 to the lead wire 7 is avoided.
In one embodiment, the feedback device further includes a first sealing plug 9 and a second sealing plug 11, as shown in fig. 2, the first sealing plug 9 is plugged into an opening at one end of the housing 1, and the heat-sensitive wire 3 extends into the interior of the housing 1 through the first sealing plug 9. The second sealing plug 11 is plugged in the opening at the other end of the shell 1, and the lead 7 passes through the second sealing plug 11 and is connected with the controller. It can be understood that the first sealing plug 9 and the second sealing plug 11 form a relatively closed space in the case 1, and when the heat-sensitive wire 3 is burned, the temperature rise speed in the case 1 is increased, and the operation of the heat-sensitive element 5 is increased. Further, if the heat sensitive element 5 comes into contact with water, a short circuit is likely to occur. A short circuit of the thermo element 5 may cause the controller to misjudge the action state of the fire extinguishing apparatus and may also cause a danger. The first sealing plug 9 and the second sealing plug 11 are matched with the shell 1, so that the overall waterproof capability is improved.
In one embodiment, the heat-sensitive wire 3 is in contact with a surface of the heat-sensitive element 5. It is understood that the heat generated by the combustion of the heat-sensitive wire 3 can be better transmitted to the heat-sensitive element 5 by directly contacting the heat-sensitive wire 3 with the heat-sensitive element 5, and the action of the heat-sensitive element 5 can be accelerated. Further, in one embodiment, referring to fig. 2, the heat-sensitive wire 3 is wound around the surface of the heat-sensitive element 5.
In some embodiments, the thermal element 5 comprises a thermistor or a temperature controlled switch. It can be understood that the resistance of the thermistor is different when the temperature is different. When the thermistor 5 is a thermistor, the operation signal of the thermistor 5 is specifically a resistance value change of the thermistor. The controller obtains the current flowing through the thermistor by applying a voltage to the thermistor through the lead 7. According to ohm's law, under the condition that the current flowing through the thermistor and the voltage thereon are known, the controller can obtain the resistance value of the thermistor, and judge whether the fire extinguishing equipment is operated according to the change of the resistance value of the thermistor, so that the feedback function is realized. When the thermosensitive element 5 is a temperature-controlled switch, the operation signal of the thermosensitive element 5 is specifically the on/off state of the temperature-controlled switch. The controller can judge whether the fire extinguishing equipment acts according to the on-off condition of the temperature control switch, and the feedback function is realized.
Further, when the thermosensitive element 5 is a temperature controlled switch, in one embodiment, the temperature controlled switch is connected with an alarm device, which includes a buzzer. When the temperature control switch acts, a buzzer of the alarm device is started, and people are reminded of timely evacuating when a fire disaster happens.
In one embodiment, the wire 7 is a high temperature resistant wire 7. It can be understood that the part of the lead 7 is also inside the shell 1, and when the heat-sensitive wire 3 burns, the sheath of the common lead 7 is easily damaged at high temperature, which affects the insulating capability of the lead 7 and brings about safety hazard. The feedback device can be ensured to normally work for a long time by adopting the high-temperature-resistant lead 7, and is not easy to be damaged due to the influence of temperature.
In one embodiment, a storage seat is disposed on the inner wall of the housing 1, and the storage seat is used for placing the heat sensitive element 5 and preventing the heat sensitive element 5 from sliding. It will be appreciated that in some application scenarios, the feedback device cannot be placed directly horizontally due to space constraints.
