[0023] Specifically, please refer to Figures 1 to 5 , Figure 1 The overall structural diagram of the power transmission line safety monitoring device provided in the embodiment of the present application is as follows: Figure 2 This is a schematic diagram of the overall cross-sectional structure of the power transmission line safety monitoring device provided in an embodiment of the present application, Figure 3 for Figure 2 A magnified view at point A. Figure 4 for Figure 2 The enlarged view at B, Figure 5The schematic diagram of the circuit principle structure at the exhaust fan provided by the embodiment of the present application. The transmission line safety monitoring device 100 includes a device body 110, a movable component 120 installed on the top of the device body 110, and a mounting component 130 fixed to the device body 110, wherein the mounting component 130 is used to connect the main body of the device to the monitoring point, and the mounting component 130 can adopt the existing technology. The movable component 120 can be lifted and dropped, and after the movable component 120 drops, it can prevent rainwater from entering the inside of the device body 110. After lifting, the airflow is less blocked, which is convenient for the device body 110 to dissipate heat in time. A partition 111 is horizontally arranged in the inner cavity of the device body 110, and a telescopic component 121 is fixed on the top of the partition 111. The telescopic component 121 can be an electric telescopic rod, etc. When the telescopic component 121 is an electric telescopic rod, it can be powered by a battery 115 provided inside the device body 110, and after being electrically connected to the PLC control box 116, it is controlled by the PLC control box 116. The telescopic component 121 can drive the rain shield 122 to rise after being extended, and vice versa, it can drive the rain shield 122 to fall. The movable component 120 includes the rain shield 122, which is in the shape of a cover with an open bottom. The top of the telescopic component 121 is fixed to the bottom wall of the rain shield 122. The outer shape structure of the rain shield 122 can be adaptively adjusted according to the actual structure of the device body 110, and its size should meet the requirements that when the rain shield 122 falls to the lowest point, the horizontal position of the lower edge of the rain shield 122 is below the horizontal position of the air inlet grille 112 and the air outlet grille 113. A limit assembly 123 is provided between the rain shield 122 and the device body 110 to limit the movement of the rain shield 122 in the vertical direction. The setting of the limit assembly 123 ensures the stability of the rain shield 122 during the up and down movement. An air inlet grille 112 and an air outlet grille 113 are respectively provided on two opposite side walls of the device body 110. An exhaust fan 114 is provided at the air outlet grille 113. When the exhaust fan 114 is working, the hot air inside the device body 110 is sucked out. At the same time, the airflow outside the device body 110 will enter the inside of the device body 110 through the air inlet grille 112 to achieve the purpose of heat dissipation. The exhaust fan 114 is connected to a battery 115, which is located inside the device body 110. The exhaust fan 114 is electrically connected to a PLC control box 116, which is used to control the exhaust fan 114 to turn it on or off. The PLC control box 116 is externally connected to the central control system, which is a prior art and is used to receive external weather information and send instructions to the PLC control box 116.

[0024] In the embodiment of the present application, under specific working conditions, when the external weather is rainy or snowy, the operator sends information instructions to the PLC control box 116 through the central control system. Further, the PLC control box 116 sends an electrical signal to the exhaust fan 114 according to the received instruction, and turns off the exhaust fan 114. At the same time, driven by the telescopic component 121, the rain shield 122 falls. At this time, rainwater will not easily enter the interior of the device body 110 through the air inlet grille 112 and the air outlet grille 113, thereby ensuring the safety of the use of various electrical components inside the device body 110. When the external weather is clear, the operator sends instructions to the PLC control box 116 through the central control system. Further, the PLC control box 116 will control the exhaust fan 114 to start up. At the same time, the telescopic component 121 drives the rain shield 122 to rise. At this time, the rain shield 122 weakens the airflow, which is convenient for rapid heat dissipation.

[0025] As can be seen from the above, in the embodiment of the present application, by setting the air inlet grille 112, the air outlet grille 113 and the exhaust fan 114, when the exhaust fan 114 is powered on, the external airflow can enter the inside of the device body 110 through the air inlet grille 112, and at the same time, the hot air inside the device body 110 can be replaced to the outside of the device body 110 through the air outlet grille 113, so that the heat dissipation inside the device body 110 can be completed efficiently, and the working efficiency of each electrical component can be ensured. The present application also sets a movable component 120, and the movable component 120 includes a rain cover 122 and a telescopic component 121. The rain cover 122 can be raised and lowered under the drive of the telescopic component 121. The rain cover 122 is controlled to fall on rainy days, and on sunny days, the rain cover 122 is controlled to rise, so as to meet the use requirements of the device in different weather conditions. At the same time, the setting of the limit component 123 will further ensure the stability of the rain cover 122 during the lifting or falling process.

[0026] In some embodiments, a floor drain plate 117 is horizontally arranged in the inner cavity of the device body 110, and multiple rain leakage holes are evenly opened on the floor drain plate. The battery 115 and the PLC control box 116 are fixed on the top of the floor drain plate, and a pouring hole 118 is opened on the bottom wall of the device body 110.

[0027] In the embodiment of the present application, through the above-mentioned arrangement, when water enters the device body 110, the rainwater will flow to the bottom of the device body 110 and be discharged through the pouring hole 118. Since the battery 115, the PLC control box 116 and other devices are located above the floor drain plate 117, they can effectively avoid being soaked in rainwater for a long time, thereby further ensuring the safety of the equipment.

[0028] In some embodiments, the limiting assembly 123 includes a limiting rod 123a connected to the bottom of the rain shield 122, and the device body 110 and the partition 111 are both provided with a limiting hole 123b that matches the limiting rod 123a. The limiting rod 123a passes through the limiting holes 123b on the device body 110 and the partition 111 in sequence and extends into the inner cavity of the device body 110. In the embodiment of the present application, through the above-mentioned setting, the limiting rod 123a can be lifted and lowered with the rain shield 122, and in this process, the limiting rod 123a always slides in the limiting hole 123b and limits its movement in the horizontal direction. Furthermore, since the limiting rod 123a is fixedly connected to the rain shield 122, the limiting rod 123a limits the movement of the rain shield 122 in the horizontal direction, thereby ensuring the stability of the rain shield 122 during the lifting and falling process.

[0029] In some embodiments, the bottom of the limiting rod 123a is connected to a blocking member 150, and the cross-sectional diameter of the blocking member 150 is larger than the aperture of the upper limiting hole 123b of the partition 111. In the embodiment of the present application, the blocking member 150 can effectively prevent the limiting rod 123a from being separated from the device body 110 through the above configuration.

[0030] In some embodiments, two arc-shaped terminals 140 are included, the exhaust fan 114, the battery 115 and the two arc-shaped terminals 140 are connected in series, and the bottom end of the limit rod 123a is connected to a conductor ball 151 that matches the two arc-shaped terminals 140. In the embodiment of the present application, the conductor ball 151 can also be used as a blocking component 150 (please refer to the above embodiment for the blocking component 150), and the rod body of the limit rod 123a can be made of insulating material. Under normal working conditions, when the rain cover 122 falls to the lowest point, the conductor ball 151 will be inserted between the two arc-shaped connection ends, and the circuit of the exhaust fan 114 is connected and can be opened and used normally. Through the above arrangement, when the movable component 120 is lifted, the limit rod 123a will be lifted together with the rain shield 122. At this time, the limit rod 123a will be separated from the two arc-shaped terminal blocks 140, and the connection between the conductor ball 151 and the two arc-shaped terminal blocks 140 will be disconnected. At this time, the exhaust fan 114 is in an open circuit state, and the exhaust fan 114 is forced to be closed, thereby effectively avoiding the exhaust fan 114 from being turned on when the rain shield 122 has not fallen due to operator error, and further avoiding water from entering the device body 110.

[0031] In some embodiments, a solar panel 160 is fixed on the top of the rain shield 122, the battery 115 is an energy storage battery 115, and the solar panel 160 is connected to the energy storage battery 115. Through the above configuration, the present application can use the solar panel 160 to charge the energy storage battery 115 to achieve energy saving.

[0032] In some embodiments, an L-shaped wiring tube 170 is provided on the side wall of the device body 110, one end of the L-shaped wiring tube 170 is connected to the device body 110, and the other end is bent downward, and the wires between the solar panel 160 and the energy storage battery 115 enter the inner cavity of the device body 110 through the L-shaped wiring tube 170, and a water-absorbing sponge 171 is provided inside the L-shaped wiring tube 170. In the embodiment of the present application, through the above arrangement, when the wire enters the device body 110, its line direction is lifted upward, and at this time, the rainwater adhering to the wire will slide down from the low point of the wire under the action of gravity, and part of the rainwater will be absorbed by the water-absorbing sponge 171, further ensuring the dryness of the inside of the device body 110.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application is described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be included in the scope of the claims and specification of the present application.
