[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figures 1 to 8 As shown, the present invention provides a safety protection device for a distribution box, including a distribution box body 1, a protection part 2 is provided on the distribution box body 1, and the protection part 2 includes an anti-collision box plate 21, and anti-collision folding plates 22 are fixedly connected on both sides of the top of the anti-collision box plate 21, and multiple solar panels 23 are fixedly connected to one end of the two anti-collision folding plates 22, and multiple light bulbs 26 are fixedly connected to the bottom ends of the two anti-collision folding plates 22, and the sunlight absorbed by the multiple solar panels 23 is converted into electrical energy to provide power for the multiple light bulbs 26, and multiple suction cups 27 are also fixedly connected to the bottom ends of the two anti-collision folding plates 22, and the anti-collision box plate 21 is provided with a rotating lifting structure for driving the two anti-collision folding plates 22 to unfold, and ventilation and heat dissipation structures are also provided on the inner walls at both ends of the anti-collision box plate 21;

[0032] T-shaped sliding blocks 24 are fixedly connected to the outer walls at both ends of the two anti-collision folding plates 22 , and T-shaped sliding grooves 25 correspondingly slidably engaged with the two groups of T-shaped sliding blocks 24 are provided on the inner walls at both ends of the anti-collision box plate 21 .

[0033] The above scheme is adopted: the solar panel 23 will be exposed through the passively unfolded anti-collision folding plate 22, so as to absorb and store solar energy, and provide electrical energy for the light bulb 26 in the later stage, so that it can light up and facilitate the maintenance work of the maintenance personnel. The anti-collision folding plate 22 will also synchronously drive the telescopic rod 232 to extend, and the passive linear downward moving anti-collision folding plate 22 will pass through the T-shaped sliders 24 installed at both ends to perform a limited sliding in the T-shaped slide groove 25, so as to ensure the stability of the unfolding and downward moving process of the anti-collision folding plate 22, until the suction cup 27 on the bottom end of the anti-collision folding plate 22 is adsorbed on the ground for positioning, thereby effectively fencing the surface of the distribution box body 1 to avoid damage to its appearance when some small collisions occur.

[0034] The rotary lifting structure includes a motor 28 of a forward and reverse rotating type fixedly connected to the inner wall of the top end of the anti-collision box plate 21, and a meshing assembly 29 is fixedly connected to the rotating shaft of the motor 28. The meshing assembly 29 is specifically composed of a horizontal bevel gear and two vertical bevel gears meshingly connected with it on both sides. A rotating wheel 230 is fixedly connected to each vertical bevel gear, and a sleeve rod is movably sleeved on the rod body of the rotating wheel 230. The top of the sleeve rod is fixedly connected to the inner wall of the top end of the anti-collision box plate 21, and a rope 231 is fixedly connected to one side of the rotating wheel 230, and the bottom end of the rope 231 is fixedly connected to the outer wall of the anti-collision folding plate 22 near the bottom. A plurality of telescopic rods 232 are specifically fixedly connected to the outer wall of the anti-collision folding plate 22 near the bottom, and the top of each telescopic rod 232 is fixedly connected to the inner wall of the top end of the anti-collision box plate 21, and two telescopic rods 232 located at the corners are fixedly connected to the rod body with rubber sleeves 233.

[0035] The above scheme is adopted: by starting the motor 28 on the anti-collision box plate 21 to drive the connected meshing assembly 29 to rotate, thereby driving the rotating wheel 230 to rotate so that the length of the rope 231 is gradually extended, and then the anti-collision folding plate 22 that is no longer passively limited will gradually unfold, so that when one set of telescopic rods 232 is passively moved downward, it will drive the connected rubber sleeve plate 233 to contact a corresponding set of groove plates 234, and be fitted and slidably connected therewith.

[0036] The two ventilation and heat dissipation structures each include a plurality of groups of slot plates 234, each group of slot plates 234 is composed of two plates, a spring 235 is fixedly connected to the outer wall on one side of the bottom end of each upper plate, and a plate groove is opened on the inner wall of the anti-collision box plate 21, which can be respectively fitted and slidably connected with each upper plate, and the bottom end of each spring 235 is respectively fixedly connected to the inner wall of the bottom end of the plate groove, and the outer wall of one end of each lower plate is fixedly connected to the inner wall of the anti-collision box plate 21, and a bellows 236 is also fixedly connected between each group of slot plates 234, and an air pipe 237 is fixedly connected to the end of each bellows 236 near the bottom, and an air cylinder 238 is fitted and slidably connected to each air pipe 237, and each air cylinder 238 is slidably connected to one end of the anti-collision box plate 21, and an air inlet groove is opened on one side of the bottom end of each air cylinder 238.

[0037] The above scheme is adopted: when the upper plate of a group of groove plates 234 is passively forced to move downward, it is forced to squeeze the spring 235 and the bellows 236 at the same time until the rubber sleeve 233 is separated from the lower plate during the downward movement process due to the resistance of the lower plate. At this time, the spring 235, which is no longer subjected to the squeezing force, will automatically drive the upper plate to reset. At the same time, when the bellows 236 is forced to generate squeezing force, the gas generated in its inner cavity will enter the air cylinder 238 through the air pipe 237. Subsequently, the air cylinder 238 impacted by the gas will slide on the air pipe 237, so that its cylinder body extends out of the anti-collision box plate 21, so that the air cylinder 238 can better receive the outside air, so that the air naturally enters the air cylinder 238 when it flows.

[0038] A curved plug plate 239 is tightly connected to the top side of each air cylinder 238, a filter screen plate 240 is fixedly connected to the inner wall of one end of each air cylinder 238, and a fan wheel 241 is also fixedly connected to the inner wall of each air cylinder 238, a rotating handle 242 is fixedly connected to the center position of each fan wheel 241, and a groove wheel plate 243 for placing refrigerant is fixedly connected to each rotating handle 242, a curved groove 244 is opened through the top side of each groove wheel plate 243, and each groove wheel plate 243 is rotatably connected to the inner wall of each air cylinder 238, a ring plate 245 is fitted and connected to the outer wall of one end of each groove wheel plate 243, and each ring plate 245 is fixedly connected to the inner wall of each air cylinder 238, and one end side wall of each groove wheel plate 243 is respectively combined with one end side wall of each ring plate 245 to open air holes.

[0039] The above scheme is adopted: the filter plate 240 installed on the air cylinder 238 can filter the gas that automatically enters. At the same time, after the gas enters the air cylinder 238, it will pass through the wind impeller 241, and the wind flow will drive the wind impeller 241 to rotate. When the axis point of the wind impeller 241 rotates, it will also synchronously drive the handle 242 and the groove wheel plate 243 to rotate. Therefore, once the air holes on the groove wheel plate 243 correspond to the air holes on the ring plate 245, the refrigerant placed in the groove wheel plate 243 will float out slightly in small quantities, thereby quickly cooling the air entering the air cylinder 238, so that the gas will then float to the outer surface of the distribution box body 1 through the air inlet groove on the air cylinder 238, cool it and increase air flow, and then the arc plug plate 239 on the air cylinder 238 can be manually pulled out, and then the refrigerant can be added to its inner cavity through the arc groove 244 on the groove wheel plate 243.

[0040] The working principle and use process of the present invention are as follows: by starting the motor 28 on the anti-collision box plate 21 to drive the meshing assembly 29 connected thereto to rotate and transmit, the rotating wheel 230 is driven to rotate so that the length of the rope 231 is gradually extended, and then the anti-collision folding plate 22 which is no longer passively limited will gradually unfold, and the passively unfolded anti-collision folding plate 22 will expose the solar panel 23, so as to absorb and store solar energy, and later provide electric energy for the light bulb 26, so that it can light up and facilitate the maintenance work of the maintenance personnel, and the anti-collision folding plate 22 will also synchronously drive the telescopic rod 232 to extend, and the anti-collision folding plate 22 which moves downward passively and linearly will pass through the T-shaped sliders 24 installed at both ends to perform limited sliding in the T-shaped slide groove 25, so as to ensure the stability of the unfolding and downward movement of the anti-collision folding plate 22, until the suction cup 27 on the bottom end of the anti-collision folding plate 22 is adsorbed on the ground for positioning, thereby effectively fencing the surface of the distribution box body 1 to avoid damage to its appearance when some small collisions occur;

[0041] When one of the telescopic rods 232 is passively moved downward, it will drive the connected rubber sleeve 233 to contact a corresponding group of slot plates 234, and be fitted and slidably connected therewith, so that the upper plate of a group of slot plates 234 is passively forced to move downward, and at the same time, it is forced to squeeze the spring 235 and the bellows 236 until the rubber sleeve 233 is resisted by the lower plate during the downward movement and is separated from it. At this time, the spring 235, which is no longer subjected to the squeezing force, will automatically drive the upper plate to reset. At the same time, when the bellows 236 is forced to generate squeezing force, the gas generated in its inner cavity will enter the air cylinder 238 through the air pipe 237, and the air cylinder 238 impacted by the gas will slide on the air pipe 237, so that its cylinder body extends out of the anti-collision box plate 21, so that the air cylinder 238 can better receive the outside air, so that the air naturally enters the air cylinder 238 when it flows. In the cylinder 238, the gas automatically entering can be filtered by the filter screen plate 240 installed on the cylinder 238. At the same time, after entering the cylinder 238, the gas will pass through the impeller 241, and the wind flow will drive the impeller 241 to rotate. When the axis point of the impeller 241 rotates, the handle 242 and the groove wheel plate 243 will be synchronously driven to rotate. Therefore, once the air holes on the groove wheel plate 243 correspond to the air holes on the ring plate 245, the refrigerant placed in the groove wheel plate 243 will float out slightly in small quantities, thereby quickly cooling the air entering the cylinder 238, so that the gas will float to the outer surface of the distribution box body 1 through the air inlet groove on the cylinder 238, cool it and increase air flow, so as to avoid the distribution box body 1 from being overheated during operation, thereby affecting the normal operation.
