DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-4 A fire monitoring device for a UHV power station includes a mounting frame 1. The mounting frame 1 is an L-shaped structure.

There are two groups of first fans 35, and the air outlets of the two groups of first fans 35 are opposite. The air outlets of the two groups of first fans 35 are both provided with partition nets. By setting the cooling mechanism in conjunction with the heat dissipation mechanism, when the electronic components are used, the air in the box body heats up, one group of the first fans guides the hot air in the box body to the top, and after being cooled by the cold end of the semiconductor refrigerator, it is discharged into the shielding cover, and the other group of first fans guides the cooled air to enter from the bottom to reduce the temperature of the electronic components in the box.

[0025] As an implementation method, please refer to Figure 2 and Figure 3 The lifting mechanism 4 includes a fixing seat 41 fixed on the side of the box body 31, a threaded column 42 is fixed inside the fixing seat 41, a threaded sleeve 43 is connected to the threaded column 42 through a thread, a first bevel gear 44 is fixedly sleeved on the threaded sleeve 43, a shell 45 is rotatably connected to the threaded sleeve 43, a motor 46 is installed on the side of the shell 45, the output shaft of the motor 46 is inserted into the inside of the shell 45 and connected to the second bevel gear 47, a connecting plate 48 is fixed on the side of the shell 45, the shell 45 is connected to the shielding cover 5 through the connecting plate 48, the first bevel gear 44 and the second bevel gear 47 are meshing transmission, the shell 45 and the fixing seat 41 are slidably connected, when in use, the shielding cover is driven to rise and fall by the lifting mechanism, so as to avoid the influence of the magnetic field in the high-voltage power station on the electronic components, thereby improving the life of the electronic components and the accuracy of the monitoring data.

[0026] As an implementation method, please refer to Figure 2 and Figure 4 The cooling mechanism 6 comprises a semiconductor refrigerator 61 installed on the top of the box body 31, a cold end 62 and a hot end 63 are respectively arranged at the bottom and the top of the semiconductor refrigerator 61, the cold end 62 is located inside the box body 31, a moisture absorption plate 64 is installed at the bottom of the cold end 62, and the top of the hot end 63 is connected to the heat dissipation mechanism 7, the heat dissipation mechanism 7 comprises a shell 71 fixed on the top of the shielding cover 5, a heat conducting plate 72 is installed at the inner bottom of the shell 71, the heat conducting plate 72 passes through the top of the bottom sliding shielding cover 5 of the shell 71, a silicone grease layer 73 is installed at the bottom of the heat conducting plate 72, and a heat dissipation fin 74 is installed on the top of the heat conducting plate 72, and a second fan 75 is installed at both ends of the shell 71, and the number of the heat dissipation fins 74 is several groups. The air inlets of the two second fans 75 are provided with partition nets, and the heat dissipation mechanism is used to assist in dissipating the heat of the hot end of the semiconductor refrigerator, thereby improving the sustainability of the use of the semiconductor refrigerator. The device has a simple structure and is very convenient to use.

[0027] The device is fixed at the workplace by means of the mounting frame 1 and bolts. The electronic components for monitoring the fire protection information of the UHV power station are installed in the box 31. Data transmission and cable connection are completed through the wire tube 32. The box door 33 is closed and the box door 33 and the box 31 are locked by means of the lock 34. The device is connected to the power supply, and the motor 46 is started. The output shaft of the motor 46 drives the second bevel gear 47 to rotate. The second bevel gear 48 drives the threaded sleeve 43 to rotate through the meshing transmission with the first bevel gear 44. The threaded sleeve 43 drives the housing 45 to slide in the fixed seat 41 through the threaded transmission with the threaded column 42. The housing 45 drives the shielding cover 5 downward through the connecting plate 48, so that the shielding cover 5 and the shielding seat 2 cooperate to completely close the box 31, thereby preventing the magnetic field in the UHV power station from affecting the electronic components in the box 31, and improving the service life of the electronic components and the accuracy of the monitoring data.

[0028] When in use, the temperature of the electronic components in the box 31 rises due to continuous operation, and the first fan 35, the semiconductor refrigerator 61 and the second fan 75 are started. When the semiconductor refrigerator 61 is in operation, the temperature of the cold end 62 decreases and the temperature of the hot end 63 increases. One group of the first fans 35 guides the hot air in the box to the top, and after cooling through the cold end 62 of the semiconductor refrigerator 61, it is discharged into the shielding cover 5. Another group of the first fans 35 guides the cooled air to enter from the bottom of the box 3 to reduce the temperature of the electronic components in the box 31 and ensure the safety of the electronic components in long-term use. Since the air in the UHV power station itself has less water content, only a small amount of condensed water appears after the hot air contacts the cold end 62, which is absorbed by the moisture absorption plate 64 at this time. The moisture absorption plate 64 can be replaced during maintenance.

[0029] When the shielding cover 5 is fully buckled with the shielding seat 2, the heat conducting plate 72 is in contact with the hot end 63 of the semiconductor refrigerator 61, and the silicone grease layer 73 fills the gap between the heat conducting plate 72 and the hot end 63 of the semiconductor refrigerator 61. When the semiconductor refrigerator 61 is operating, the hot end 63 generates heat, and the heat is transferred to the heat dissipation fins 74 via the silicone grease layer 63 and the heat conducting plate 72. The two second fans 75 accelerate the air flow in the shell 71, and the heat dissipation fins 74 are dissipated by the flowing air, thereby achieving the cooling of the hot end 63 of the semiconductor refrigerator 61, avoiding excessive heat accumulation at the hot end 63, and ensuring the sustainability of the operation of the semiconductor refrigerator 61.

[0030] To sum up, compared with the prior art, the electronic components used for fire monitoring in the present invention are installed inside the box, and the power supply and data transmission are connected through wire pipes. When in use, the shielding cover is driven to rise and fall by the lifting mechanism, which can avoid the influence of the magnetic field in the high-voltage power station on the electronic components, thereby improving the life of the electronic components and the accuracy of the monitoring data. At the same time, by setting a cooling mechanism to cooperate with the heat dissipation mechanism, when the electronic components are in use, the air in the box is heated up, and one group of first fans guides the hot air in the box to the top, and after being cooled by the cold end of the semiconductor refrigerator, it is discharged into the shielding cover. Another group of first fans guides the cooled air to enter from the bottom, thereby reducing the temperature of the electronic components in the box, and at the same time, the heat dissipation mechanism is used to assist in dissipating the hot end of the semiconductor refrigerator, thereby improving the sustainability of the use of the semiconductor refrigerator. The device has a simple structure and is very convenient to use.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
