Description

Technical Field

[0001] This utility model relates to fire early warning technology, specifically to an early warning device for early monitoring of fires in substations. Background Technology

[0002] Substations are crucial facilities in power systems, used to convert high-voltage electricity into low-voltage electricity, or vice versa, for power distribution and transmission. They also monitor and protect the power system, ensuring a safe and stable power supply. Substations are typically divided into high-voltage substations and distribution substations. They are widely used in cities, industrial areas, power plants, wind and solar power plants, and transportation infrastructure such as railways. Their primary function is to convert high-voltage electricity into low-voltage electricity to meet the power needs of residents, businesses, industry, and transportation, while also providing a stable power supply to remote areas and ensuring the normal operation of the power system.

[0003] Patent application number 202323265382.4 discloses a substation fire monitoring device, including a fixed rod with a counterweight at the bottom and a fixed plate above it. The fixed plate has a first protrusion on its upper surface, a protective cover above the first protrusion, and a shielding cover above the protective cover. This substation fire monitoring device achieves overall height adjustment by connecting the fixed plate with a plug rod and tightening bolts. A limiting ring with a battery pack is installed on the fixed plate, providing overall power. The protective cover connects the shielding cover and the fixed plate, and includes a filter screen to help intercept dust particles and insects. A hanging seat with a smoke alarm facilitates fire monitoring of the accessories, and a temperature sensor helps monitor the ambient temperature.

[0004] However, when monitoring fires in substations, it is impossible to accurately and quickly identify areas where fires may occur, leaving staff with insufficient time for emergency response. To improve the accuracy and timeliness of monitoring, a large number of monitoring devices need to be installed on site, which is costly and difficult to maintain. Utility Model Content

[0011] Furthermore, a second insertion interface is provided at the top of a section of the monitoring sub-pipe near the main monitoring pipe and the fan, and the pyrolysis particle fire detector is fixedly inserted into the second insertion interface.

[0012] Preferably, the sealing mechanism includes a sealing plate and a drive plate.

The top of the sealing plate is provided with two connecting rods that are connected and fixed to the drive plate. Two sliding slots are symmetrically opened on both sides of the top of the monitoring sub-pipe. The two connecting rods pass through the corresponding sliding slots and are slidably connected to the sliding slots. The drive plate is located at the top of the monitoring sub-pipe and is connected to the drive mechanism.

[0013] Furthermore, the drive mechanism is located at the top of the monitoring sub-pipe, and the drive mechanism includes a forward and reverse motor, which is fixedly installed at the top of the monitoring sub-pipe. The output shaft of the forward and reverse motor is fixedly connected to a drive screw, which is arranged parallel to the monitoring sub-pipe.

[0014] Furthermore, limit plates are provided on the top of both sides of the monitoring sub-pipe, the drive plate is located between the two limit plates, and support plates for supporting the drive screw are provided at both ends of the top of the monitoring sub-pipe. Bearings are installed on the support plates, and the two ends of the drive screw are rotatably connected to the corresponding support plates through the bearings.

[0015] Preferably, the bottom of the monitoring sub-pipe is connected to a dust collection trough, which is located on the side of the filter screen mounting groove away from the main monitoring pipe, and a dust collection trough is installed on the dust collection trough.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) This utility model can detect the particle release of all the sub-distribution cabinets below the monitoring sub-distribution pipes by installing a pyrolysis particle fire detector in the first plug-in interface of the monitoring main pipe. A fan is installed to quickly send the air below the air inlet into the pipe. By measuring the particle concentration in real time, the fire monitoring and early warning function is achieved. Furthermore, by installing pyrolysis particle fire detectors on the monitoring sub-distribution pipes, each monitoring sub-distribution pipe can operate independently, which can more accurately and quickly find out which row of distribution cabinets has an excessive particle concentration.

[0020] (2) This utility model adopts the cooperation of a drive mechanism and a sealing mechanism. The drive screw is rotated by a forward and reverse motor, which in turn drives the sealing plate to slide in the monitoring sub-pipe. It can adjust the number of air inlets connected to the pipe in real time. By changing the air inlet section on the monitoring sub-pipe, the location of the abnormal power distribution cabinet can be found more specifically. Thus, a minimum number of pyrolysis particle fire detectors can be used to monitor and warn of abnormal locations of power distribution cabinets, further improving the accuracy of monitoring.

[0021] (3) The present invention is also provided with a dust collection trough, which can temporarily store the dust accumulated on the filter screen plate in the pipeline. The bottom plate of the dust collection trough can be disassembled, so that the staff can clean the dust accumulated in it regularly. This can avoid the situation where the equipment cannot operate normally due to excessive dust accumulation, which is conducive to the long-term stable operation of the device, increases the service life of the device and improves the use effect.

[0029] The present invention will be further described in detail below with reference to specific embodiments. These descriptions are for illustrative purposes only and not for limiting the scope of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] refer to Figure 1 and Figure 2As shown, this utility model provides an early warning device for substation fire early warning monitoring, including a main monitoring pipeline 100, which is closed at both ends. Multiple connecting ports 110 are equidistantly arranged on one side of the main monitoring pipeline 100, and each connecting port 110 is fixedly connected to a monitoring branch pipeline 200. An air outlet 120 is provided on the other side of the main monitoring pipeline 100, and a first insertion interface 121 is provided at the top of the air outlet 120. A pyrolysis particle fire detector 300 is fixedly inserted into the first insertion interface 121. A fan 500 is installed at one end of the monitoring branch pipeline 200 near the connecting port 110. Several air inlets 270 are evenly arranged at the bottom of the monitoring branch pipeline 200. The fan 500 can send air below the air inlets 270 into the pipeline, and the air is detected by the pyrolysis particle fire detector 300 after passing through it. Both the main monitoring pipeline 100 and the monitoring branch pipeline 200 are fixedly installed on the indoor ceiling of the substation via brackets 400.

[0031] For example, refer to Figure 3 and Figure 6 As shown, a fan mounting groove 220 is provided inside a section of the monitoring sub-pipe 200 near the monitoring main pipe 100. The fan 500 is installed in the fan mounting groove 220. A filter screen mounting groove 230 is provided on the side of the fan mounting groove 220 away from the monitoring main pipe 100. A filter screen plate 600 is installed in the filter screen mounting groove 230.

[0032] Further, refer to Figure 4 As shown, a second insertion interface 210 is provided at the top of a monitoring sub-pipe 200 between the main monitoring pipe 100 and the fan 500. A pyrolysis particle fire detector 300 is also fixedly connected to the second insertion interface 210, so that each monitoring sub-pipe 200 can work independently and can quickly detect which row of distribution cabinets has an excessive particle concentration. When a row of distribution cabinets overheats and causes the particle concentration to increase, it indicates that a fire may occur. At this time, the pyrolysis particle fire detectors 300 on the two closest monitoring sub-pipes 200 above this row of distribution cabinets will detect the abnormality at the same time. Thus, the staff can immediately know which row or rows of distribution cabinets overheated and caused the particle concentration to increase, thereby achieving the function of rapid and accurate monitoring and early warning.

[0033] For example, the top of the monitoring sub-pipe 200 is also provided with a drive mechanism 700 for adjusting the air inlet. The drive mechanism 700 includes a forward and reverse motor 710, which is fixedly installed on the top of the monitoring sub-pipe 200 near the filter screen mounting groove 230. The output shaft of the forward and reverse motor 710 is fixedly connected to a drive screw 720. A sealing mechanism 800 for controlling the air intake quantity of the air inlet 270 is threaded onto the drive screw 720. Two sliding slots 260 are symmetrically opened on both sides of the top of the monitoring sub-pipe 200, and the sliding slots 260 are slidably connected to the sealing mechanism 800.

[0034] Further, refer to Figure 5 As shown, the sealing mechanism includes a sealing plate 810 and a drive plate 820. The side of the sealing plate 810 is in close contact with the inner wall of the monitoring sub-pipe 200 and is slidably connected to the inner wall of the monitoring sub-pipe 200. The top of the sealing plate 810 is fixedly connected to the drive plate 820 by two connecting rods 830. The drive plate 820 is located at the top of the monitoring sub-pipe 200 and is threadedly connected to the drive screw 720 by a threaded opening 821. The two connecting rods 830 pass through the corresponding sliding slots 260 and are slidably connected to the sliding slots 260.

[0035] By starting the forward and reverse motor 710 to control the rotation of the drive screw 720, the drive plate 820 is moved on the drive screw 720. Since the connecting rod 830 slides in the sliding groove 260 and connects and fixes the partition plate 810 and the drive plate 820 together, the partition plate 820 can slide in the inner wall of the monitoring sub-pipe 200 under the rotation of the drive screw 720, thereby realizing the control of the air intake quantity of the air inlet 270. Therefore, under the real-time monitoring of the pyrolysis particle fire detector 300, it is possible to find out in time which specific location of the power distribution cabinet is abnormal, further improving the accuracy of monitoring.

[0036] Furthermore, limit plates are provided on the top of both sides of the monitoring sub-pipe 200, with the drive plate 820 located between the two limit plates. Support plates 730 for supporting the drive screw 720 are provided at both ends of the top of the monitoring sub-pipe 200. Bearings 740 are installed on the support plates 730, and both ends of the drive screw 720 are rotatably connected to the corresponding support plates 730 through the bearings 740, allowing the drive screw 720 to move smoothly. The two limit plates that limit the position of the drive plate 820 also improve the operational stability of the drive plate 820.

[0037] Furthermore, the bottom of the monitoring sub-pipe 200 is connected to a dust collection trough 240 on the side of the filter screen mounting groove 230 away from the main monitoring pipe 100. A dust collection trough 900 is installed on the dust collection trough 240. The dust collection trough 900 includes a trough body 910 and a bottom plate 920. The trough body 910 is a rectangular frame fixed to the top of the bottom plate 920 and is inserted into the dust collection trough 240. Mounting ear plates 930 are fixed on both sides of the bottom plate 920 and are connected to the dust collection trough 240 by screws. This structural design allows the dust accumulated on the filter plate 900 to fall into the dust collection trough 900. When cleaning is required, the ear plates 930 can be disassembled, which facilitates timely cleaning of dust. At the same time, the dust collection trough 240 is also conducive to cleaning the filter screen plate 600.

[0038] For example, the bracket 400 includes a support plate 410, a receiving rod 420, and a nut 430. The support plate 410 is located at the bottom of the corresponding pipe, and the receiving rods 420 are vertically arranged at both ends of the support plate 410. One end of the receiving rod 420 connected to the support plate 410 is fixedly connected to the nut 430 by threads. The nut 430 is located at the bottom of the support plate 410, and the end of the receiving rod 420 away from the nut 430 is fixedly connected to the indoor ceiling of the substation.

[0039] The above description is a further detailed explanation of the present utility model in conjunction with specific embodiments. It should not be considered that the specific implementation of the present utility model is limited to these utility models. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the protection scope of the present utility model.
