Detailed Description
The invention will be further elucidated and described with reference to the drawings and the detailed description. The technical features of the embodiments of the present invention can be combined correspondingly without mutual conflict.
As shown in fig. 1, in a preferred embodiment of the present invention, a permanently-adjacent combined automatic spraying system for a mountain steel structure plank road is provided, which mainly comprises permanent spraying equipment 3, temporary spraying pipelines 7 and mobile spraying equipment arranged on each firing equipment 8.
As shown in fig. 2, the permanent spraying equipment 3 and the permanent fire-fighting water supply pipeline 4 are installed on each constructed main body structure of the trestle, and the installation process can be performed synchronously with the construction of the main body structure of the trestle as long as the construction conditions are met. The permanent spraying equipment 3 and the permanent fire-fighting water supply pipeline 4 are generally fixedly arranged on steel structural members at two sides of the trestle, and the specific fixing mode is not limited so as to ensure the fixing strength of the trestle. The permanent shower device 3 can generally be realized as an open-pored shower. The adjacent permanent fire-fighting water supply pipeline 4 of striding needs to be connected section by section, forms continuous water supply line, and the permanent fire-fighting water supply pipeline 4 of foremost needs to be connected fire-fighting water tank 2. The fire water tank 2 is supplied with water from a water source, but the fire water tank 2 itself should have a certain water storage capacity to avoid emergency use by itself when the water source cannot supply water. The permanent spraying equipment 3 is arranged in a single span mode, namely the permanent spraying equipment 3 on each span of the stack pipeline is respectively connected with the permanent fire-fighting water supply pipeline 4, the control valves of the permanent spraying equipment 3 are independent valves, and the permanent spraying equipment 3 on each span can independently control the spraying state.
It should be noted that, although the permanent spraying equipment 3 and the permanent fire-fighting water supply pipeline 4 in the invention are mainly used as permanent fire-fighting facilities after the completion of the trestle, they can also function as temporary fire-fighting facilities in the construction process of the trestle, so that too many temporary fire-fighting facilities do not need to be repeatedly arranged in the construction process, the construction process is maximally reduced, and the construction cost is reduced. Therefore, after the permanent spraying equipment 3 and the permanent fire-fighting water supply pipeline 4 are constructed synchronously with the main structure of the trestle, the permanent spraying equipment and the permanent fire-fighting water supply pipeline are tested and accepted in advance and put into use before the subsequent construction of the trestle.
In addition, considering the requirement of fire prevention in mountain and forest areas, fire hydrants are required to be arranged on the constructed main structure of the plank road at intervals according to the fire-fighting requirement, and the requirement that a water hose or other fire-fighting facilities are required to be connected when fire fighting is carried out in forest areas is met. As shown in figure 3, the fire hydrant used in the invention is an embedded fire hydrant 5, which can be embedded into the main structure of the gallery as a whole, and the opening of the fire hydrant is positioned on the surface of the gallery, thereby reducing the occupied area. Each in-line hydrant 5 is connected to the permanent fire fighting water supply pipe 4 to take water. The spacing between adjacent in-line hydrants 5 is adjusted according to actual fire fighting needs, and is not limited thereto, and should not exceed 30m in general.
In addition, besides the already constructed main structure of the plank road, a temporary spraying pipeline 7 should be installed on the main structure of the next-span plank road to be constructed, that is, the temporary spraying pipeline 7 should be constructed ahead of the main structure of the plank road, so as to meet the requirement of spraying and cooling in the area of the plank road to be constructed. As shown in fig. 3, the temporary spraying pipeline 7 is provided with a plurality of spraying heads with spraying holes for spraying and cooling the coverage area below the crossing stack. Similarly, the temporary spray line 7 also needs to be connected to the permanent fire water supply pipeline 4 on the first-span pipeline, but in consideration of the actual situation of the part, the gate valve adopted by the temporary spray line can be controlled independently, generally by using a manual control valve, and can be manually unscrewed by constructors before construction.
In addition, each span plank road is also provided with a fire monitoring device 6, and the fire monitoring device 6 is generally arranged on a supporting pier of the plank road. The fire monitoring device 6 is mainly composed of two parts, one part is a thermal sensing monitoring system for monitoring whether a fire point exists in the area below the plank road, and the other part is a first positioning system for acquiring position information. The thermal sensing monitoring system can be realized by adopting an infrared thermal imaging device or other similar high-temperature area detection devices, is mainly used for detecting the ignition point of an open fire, and can also be used for detecting high-temperature abnormity about to ignite.
In addition, in the construction process of the steel structure plank road, equipment needing fire driving is often needed, and fire hazard is easily caused by the equipment. In the traditional method, during fire construction, a safety worker needs to send water to cool and extinguish fire at a fire point, but the invention directly adopts special fire equipment so as to realize automatic spraying and remote monitoring.
As shown in fig. 5, each fire equipment 8 includes a fire equipment body 801, a fire sensing device 802 and a movable spraying equipment 803, the movable spraying equipment 803 is temporarily connected with a permanent fire-fighting water supply pipeline 4 near the fire position through a connecting pipeline 805, the movable spraying equipment 803 and the fire equipment body 801 are synchronously controlled through a controller 804, and the fire sensing device 802 can monitor whether the fire equipment body 801 is in a fire operation working state, and a sensing signal is sent to the controller 804, so that the movable spraying equipment synchronously and automatically sprays and cools the fire equipment body when the fire equipment body works, and the spraying is automatically finished after the fire operation is finished. Each of the fire equipments 8 is further provided with a second positioning system, and the second positioning system can acquire current position information so as to manage the current position information.
In the invention, all the permanent spraying equipment 3, the first positioning system, the fire monitoring equipment 6, the fire sensing device and the second positioning system need to be remotely connected with the cloud platform 9 through communication equipment, and can send respective data to the cloud platform 9 and receive unified scheduling management of the cloud platform 9. In order to realize the remote connection control between each device and the cloud platform 9, the permanent spraying device 3, the first positioning system, the fire monitoring device 6, the fire sensing device and the second positioning system need to be connected with a lower computer, the lower computer forms data interaction with the cloud platform 9 through wired or wireless communication equipment, and the lower computer sends the data of each connected device and receives a scheduling instruction of the cloud platform 9 to control each connected device. However, it should be noted that the lower computer and the communication device may be one or multiple ones, that is, each of the various devices or sensors may be connected to the cloud platform 9 through different lower computers and communication devices, or may be connected to the cloud platform 9 through a unified lower computer and communication device. Similarly, the lower computer connected to each device may be a control device of the device itself, or may be an external control device, which is not limited to this.
In addition, the first positioning system and the second positioning system in the invention can adopt a GPS positioning system, a beidou positioning system or similar positioning equipment, which is not limited to this.
After the cloud platform 9 forming the unified scheduling management is constructed, the specific positions of various fire-fighting devices 8 and the monitoring results of various fire-fighting monitoring devices 6 in the construction process of the trestle can be known globally from the cloud platform 9, and corresponding fire-fighting measures are set for fire-fighting operation in which a fire easily occurs. As the most basic function, the cloud platform 9 needs to acquire the monitoring data and the positioning data of the fire monitoring device 6 and the fire device 8 in real time, and find the fire risk, specifically, the fire risk includes at least two aspects: the first aspect comprises that the fire monitoring equipment 6 monitors the fire points existing in the area below the stack road and the positions of the fire points acquired by the first positioning system, and can judge that the fire points exist in a certain area and determine the position information of the area; the second aspect includes the positioning information sent by the second positioning system and the sensing signal of the fire sensing device 802, from which the fire operation of the fire equipment 8 at the constructed plank road can be found. When the cloud platform 9 finds that any one of the fire risks in the two aspects appears in the construction process of the gallery road through calculation and analysis, a control instruction needs to be sent to the lower computer, the permanent spraying equipment 3 at the fire-starting point or the fire-working position where the fire risk appears is opened through the corresponding lower computer, and then the lower area is sprayed and cooled, so that mountain and forest fires are prevented from appearing. Through the method, in the construction process of the plank road, numerous security personnel do not need to be arranged for monitoring or fire-fighting operation, so that the construction cost is greatly reduced, and the management of construction fire is more meticulous and standard.
It should be noted that, in the construction process of the steel structure plank road, the main body of the fire equipment 8 is generally a welding machine, which is easy to generate open fire. When the firing operation is carried out in the finished gallery main structure area, the spraying is divided into two aspects: the first aspect is the spraying operation of the spraying facilities on the plank road, the welder fire induction device installed on the fire equipment 8 and the positioning can transmit the fire information and the fire position information to the cloud platform 9, the cloud platform 9 automatically opens the permanent spraying equipment 3 on the main structure of the plank road, and the spraying cooling is implemented; when the fire equipment 8 stops firing, the permanent spraying equipment 3 stops spraying; when fire is started in an area where the main body structure is not constructed, the corresponding gate valve on the temporary fire pipeline 7 needs to be manually opened to carry out spraying and cooling; the second aspect is the spraying operation of the mobile spraying equipment carried by the fire equipment 8, when welding operation is carried out, the controller of the fire equipment 8 opens the power supply of the mobile spraying equipment to carry out spraying cooling on a welding position, and after the operation is finished, the controller closes the power supply of the spraying equipment.
Of course, in addition to the welding machine, other firearms should be incorporated into the unified management of the firearms 8 in the present invention.
As shown in fig. 6, in the construction process of a steel structure plank road, the firing equipment 8 may be needed at a plurality of positions according to different construction organization sequences. Therefore, if a plurality of fire equipment 8 exist, each fire equipment 8 needs to be accessed to the cloud platform 9 for unified management.
In addition, in order to facilitate the construction manager to realize remote fire risk monitoring and commanding, the mobile terminal 10 which is in communication connection with the cloud platform 9 can be arranged according to needs, and the mobile terminal 10 can obtain various monitoring data and alarm signals from the cloud platform 9, so that the conditions of various construction sites can be known remotely from the mobile terminal 10. In addition, in order to facilitate emergency handling, the mobile terminal 10 may be given corresponding control authority so that a manager can control the on and off of each permanent spraying device 3 through the cloud platform 9, thereby manually controlling the fire-fighting equipment if necessary.
Similarly, in addition to the mobile terminal 10, the cloud platform 9 may be connected to the field monitoring feedback screen 1, and is configured to display various monitoring data and alarm signals through a screen at a project commander or other management departments, and serve as a control platform for field monitoring personnel, so as to monitor fire risks in a construction process and implement emergency control on fire-fighting facilities.
In conclusion, the temporary fire-fighting spraying system in the construction process of the invention essentially comprises two parts, wherein the first part of the temporary fire-fighting spraying system is an automatic spraying system for permanent fire fighting, comprises a permanent spraying device 3, a permanent fire-fighting water supply pipeline 4 and the like, is constructed synchronously with the main structure of the trestle pipeline and is tested and accepted in advance to serve as a part of a temporary fire-fighting facility covering the subsequent fire-fighting construction operation; the other part of the spraying pipeline 7 is constructed in a way of leading the main structure of the gallery road, and the gate valve can be opened to cover, spray and cool when the next structure of the gallery road is constructed. In the process of construction, the original permanent fire-fighting facilities which are put into use after the whole construction is finished can be used as temporary fire-fighting facilities required by construction in advance, so that the cost required by construction is greatly reduced.
And the temporary spraying pipeline 7 is continuously recycled, and the temporary spraying pipeline 7 can be detached and moved to the next span position without completing the construction of the main structure of the span gallery. But permanent fire-fighting facilities are directly and permanently arranged in the gallery road after acceptance check is passed, the gallery road is put into practical use after construction is completed, thermal sensing monitoring information and positioning information are sent to the cloud platform 9 in real time, the cloud platform 9 analyzes and judges whether open fire exists or not through the thermal sensing monitoring information, if the open fire occurs, the permanent spraying equipment 3 on the main structure of the gallery road is automatically opened, spraying fire extinguishment is implemented, and the open fire position and related monitoring information are sent to the mobile terminal 10, so that related personnel are reminded to take measures. In addition, the cloud platform 9 may further perform analysis in combination with real-time weather information when determining whether there is an open fire, for example, when an open fire is found in a weather condition that is not likely to have an open fire, such as rainfall or snowfall, it may be regarded as misjudgment at a large probability, and when an open fire is found in other weather that is likely to have an open fire, it needs to be disposed of in time.
