[0032] Refer to Figure 1 As shown, the present utility model provides a technical solution: a protective box for rail transit electrical facilities, including a protective box body 1 and a rotating bracket 206. A ventilation structure 2 is provided on the surface of the protective box body 1. By setting the ventilation structure 2, the interior of the protective box can be ventilated on sunny days, effectively dissipating the heat generated by the equipment inside the protective box, preventing the equipment from overheating and overloading, and improving the stability and lifespan of the equipment. A cleaning structure 3 is provided on the surface of the rotating bracket 206. By setting the cleaning structure 3, the dust-proof net 207 on the ventilation structure 2 can be cleaned, so that the dust on the dust-proof net 207 will not block the dust-proof net 207.

[0033] Next, specifically describe the specific settings and functions of its ventilation structure 2 and cleaning structure 3.

[0034] Refer to Figure 3 、 Figure 5 and Figure 6As shown in the figure, in this embodiment: The ventilation structure 2 includes two connecting plates 215. The surfaces of the two connecting plates 215 are fixedly connected to the protective box body 1. Two connecting grooves 216 are formed on the surface of the connecting plate 215. Four positioning rods 203 are slidably connected to the inner walls of the four connecting grooves 216. A baffle 201 is fixedly installed on the surfaces of the four positioning rods 203. A sealing sleeve 202 is fixedly sleeved on the surface of the baffle 201. The surface of the baffle 201 is slidably connected to the protective box body 1. The surface of the sealing sleeve 202 abuts against the protective box body 1. A nut 204 is threadedly connected to the arc surface of the positioning rod 203. The surface of the nut 204 abuts against the connecting plate 215. A fixing frame 205 is fixedly installed on the surface of the protective box body 1. A rotating frame 206 is rotatably connected to the surface of the fixing frame 205. A dust-proof net 207 is fixedly installed inside the rotating frame 206. When the protective box is ventilated, the dust-proof net 207 can prevent dust and other sundries from entering the protective box. Two rubber pads 208 are fixedly installed on the surface of the fixing frame 205. The rubber pads 208 can reduce the force when the rotating frame 206 hits the connecting plate 215. Two clamping rods 209 are slidably inserted into the fixing frame 205. A square plate 210 is rotatably connected to the surface of the clamping rod 209. A circular plate 213 is fixedly installed at one end of the clamping rod 209 away from the square plate 210. A spring 212 is sleeved on the arc surface of the clamping rod 209. The two ends of the spring 212 are fixedly connected to the fixing frame 205 and the circular plate 213 respectively. Due to the limitation of the square plate 210, the rotating frame 206 is not easy to rotate, achieving the effect of fixing the rotating frame 206 and the connecting plate 215. Limiting holes 211 are formed on the surfaces of the two square plates 210. Two connecting columns 214 are fixedly inserted into the rotating frame 206. The size of the connecting column 214 is adapted to the size of the limiting hole 211. By inserting the connecting column 214 into the inner wall of the limiting hole 211 on the square plate 210, the square plate 210 is not easy to rotate inside the rotating frame 206.

[0035] Referring to Figure 2 As shown in the figure, specifically, the cleaning structure 3 includes two brushes 32. The surfaces of the two brushes 32 are slidably connected to the rotating frame 206. A sliding frame 31 is fixedly installed on the surfaces of the two brushes 32. The surface of the sliding frame 31 is slidably connected to the rotating frame 206. Two extrusion frames 33 are threadedly connected to the inside of the sliding frame 31. The surfaces of the extrusion frames 33 abut against the rotating frame 206. Cylinders 35 are rotatably sleeved on the surfaces of the two extrusion frames 33. An installation rope 34 is fixedly installed on the surface of the cylinder 35. The surface of the installation rope 34 is fixedly connected to the sliding frame 31. The cylinders 35 and the installation rope 34 can prevent the extrusion frames 33 from moving out of the inside of the sliding frame 31.

[0036] Working principle: When the inside of the protective box overheats, turn the nut 204. The nut 204 moves downward by means of the thread. After the nut 204 moves a certain distance, the nut 204 moves out of the surface of the positioning rod 203. At this time, the fixation between the baffle 201 and the protective box is lost. Then remove the baffle 201. At this moment, there is no obstruction above the protective box, and heat dissipation can be carried out. Subsequently, turn the rotating frame 206. After the rotating frame 206 rotates a certain angle, the surface of the rotating frame 206 contacts the protective box. Then slide the round plate 213 upward. While the round plate 213 slides, it drives the clamping rod 209 to slide. While the clamping rod 209 slides, it drives the square plate 210 to slide. After the square plate 210 slides to the required position, stop sliding the round plate 213. Then turn the square plate 210. When the limiting hole 211 on the square plate 210 is located above the connecting column 214, stop turning the square plate 210. Then release the round plate 213. At this time, the round plate 213 slides downward under the elastic force of the spring 212. While the round plate 213 slides, it drives the positioning rod 203 to slide. While the positioning rod 203 slides, it drives the square plate 210 to slide. After the square plate 210 slides a certain distance, the square plate 210 is sleeved on the connecting column 214 by means of the limiting hole 211. At this time, the rotating frame 206 is limited on the protective box. At this time, when the protective box is ventilated, the dust-proof net 207 can prevent dust and other sundries from entering the protective box. By setting the ventilation structure 2, the inside of the protective box can be ventilated on sunny days, which can effectively dissipate the heat generated by the internal equipment of the protective box, prevent the equipment from overheating and overloading, and improve the stability and service life of the equipment.

[0037] When there is a lot of dust accumulated on the dust-proof net 207 of the ventilation structure 2, turn the extrusion frame 33. The extrusion frame 33 moves away from the baffle 201 by means of the thread. After the extrusion plate moves a certain distance, the surface of the extrusion plate no longer extrudes the rotating frame 206. Then slide the sliding frame 31 by means of the extrusion frame 33. While the sliding frame 31 slides, it drives the brush 32 to slide. While the brush 32 slides along the rotating frame 206, the brush 32 removes the dust on the dust-proof net 207. By setting the cleaning structure 3, the dust-proof net 207 of the ventilation structure 2 can be cleaned, so that the dust on the dust-proof net 207 will not block the dust-proof net 207.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
