[0003] A Chinese patent with the publication number CN107492826B discloses a high-voltage switch cabinet, which includes a low-voltage chamber, a handcart chamber, a busbar chamber, and a cable chamber. Pressure relief plates are provided at the tops of the handcart chamber, the busbar chamber, and the cable chamber. A movable door is provided inside the handcart chamber. A handcart is provided on one side of the movable door and the handcart is located at the bottom of the low-voltage chamber. A contact box is provided inside the busbar chamber. The contact box includes an upper contact box and a lower contact box. The upper end of the upper contact box is connected to the main busbar. A wall bushing is provided outside the main busbar. A shielding cover is provided at the bottom of the upper contact box. The shielding cover is a kind of fine wire metal mesh. Contact box support plates are provided at both the upper and lower ends of the contact box. Load-bearing reinforcing ribs are provided on the contact box support plates.

[0004] Currently, in the existing technology, there is generally a lack of an anti-smashing buffer structure at the top of high-voltage switch cabinets. With the gradual deterioration of the natural environment, the probability of hail weather in some parts of our country has increased year by year. Hail falling on the top of outdoor high-voltage switch cabinets will cause greater damage to the switch cabinets, resulting in a reduction in the service life of the high-voltage switch cabinets.

[0005] Therefore, the present invention provides an anti-smashing high-voltage switch cabinet with a top buffer structure and its usage method. Summary of the Invention

[0006] In order to make up for the deficiencies of the existing technology and solve at least one of the technical problems proposed in the background art.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: A high-voltage switchgear with a top buffer structure according to the present invention includes a cabinet body; ventilation boxes are fixedly connected to both sides of the cabinet body, and ventilation openings are provided on the ventilation boxes; a fan is rotatably connected inside the ventilation box on one side of the cabinet body, and the fan is driven by a motor and a rotating shaft; a buffer box is fixedly connected to the top of the cabinet body; a top plate is slidably connected inside the buffer box; an elastic layer is fixedly connected to the upper side of the top plate; a group of springs are fixedly connected between the lower side of the top plate and the bottom of the buffer box. In the prior art, there is generally a lack of an anti-smashing buffer structure on the top of the high-voltage switchgear. With the gradual deterioration of the natural environment, the probability of hail weather in some parts of our country has increased year by year. Hail falling on the top of the outdoor high-voltage switchgear will cause greater damage to the switchgear, resulting in a reduction in the service life of the high-voltage switchgear. At this time, the present invention sets a buffer box on the top of the cabinet body. Hail will fall on the top plate, and the elastic layer and the springs are used to provide a buffering function for the high-voltage switchgear. And by setting ventilation boxes and ventilation openings, when the high-voltage switchgear is operating normally, the motor can drive the fan to rotate, forming a flowing air current inside the cabinet body, improving the heat dissipation effect of the high-voltage switchgear.

[0008] Preferably, a collection port is provided on the elastic layer and the top plate; a water guide pipe is communicated with the bottom of the buffer box; the water guide pipe extends into the cabinet body, and a loop is formed between the water guide pipe and the buffer box. After the hail falls on the surface of the top plate, it will enter the buffer box through the collection port, thus collecting the hail. After the hail melts into water, the water enters the water guide pipe. By making the water guide pipe in insulated contact with each electrical appliance inside the cabinet body, it can provide a water cooling function for the electrical appliances, further improving the heat dissipation effect of the high-voltage switchgear.

[0009] Preferably, the rotating shaft penetrates through the water guide pipe and is rotatably and hermetically connected thereto; a first bevel gear is fixedly connected to the outer side of the rotating shaft inside the water guide pipe; a rotating rod is rotatably connected to a position near the rotating shaft inside the water guide pipe through a bracket; a screw conveyor is fixedly connected to one end of the rotating rod, and a second bevel gear is fixedly connected to the other end of the rotating rod, and the first bevel gear meshes with the second bevel gear. When the motor drives the fan to rotate through the rotating shaft, it will synchronously drive the first bevel gear and the second bevel gear to rotate, and then drive the rotating rod and the screw conveyor to rotate, so that the water inside the water guide pipe flows, forming a circulating water path, facilitating the removal of the heat of each electrical appliance inside the cabinet body, and further improving the heat dissipation effect of the high-voltage switchgear.

[0010] Preferably, a first sleeve and a second sleeve are sleeved outside the spring, and the first sleeve is slidably connected inside the second sleeve; the first sleeve is fixedly connected to the lower side of the top plate, and the second sleeve is fixedly connected to the bottom of the buffer box. By setting the first sleeve and the second sleeve, when the hail falls on the top plate, the first sleeve will slide inside the second sleeve, which can isolate the spring from the hail inside the buffer box, avoiding the problem that the hail gets stuck inside the spring, resulting in the spring being unable to expand and contract normally.

[0011] Preferably, a guide rod is slidably connected inside the collection port; an elastic strip is fixedly connected between the guide rod and the side wall of the collection port; an arc-shaped plate is fixedly connected to the top of the guide rod; by providing the guide rod and the arc-shaped plate, the arc-shaped plate can block the collection port, preventing hail from directly hitting the bottom of the buffer box through the collection port, thus avoiding the problem of the inability to achieve a buffering effect. Moreover, due to the arc-shaped surface of the arc-shaped plate, hail will not accumulate in large quantities on the upper side of the arc-shaped plate. When the hail hits the arc-shaped plate, it will drive the arc-shaped plate and the guide rod to move downward, and the elastic strip can play a buffering effect on the arc-shaped plate, improving the service life of the arc-shaped plate.

[0012] Preferably, a group of puncture needles are fixedly connected to the bottom of the guide rod, and the multiple puncture needles are fixedly connected by a connecting rod; a rubber plate is fixedly connected to the bottom of the buffer box; a group of triangular teeth are evenly distributed on the upper side of the rubber plate; by providing the rubber plate and the triangular teeth, after the hail falls into the buffer box through the collection port, it will directly hit the tip of the triangular teeth, facilitating the crushing of the hail. At the same time, when the guide rod moves downward, it will push the hail around through the multiple puncture needles, increasing the storage capacity of the hail. Moreover, the puncture needles can further crush the hail, accelerating the melting speed of the hail and further increasing the storage capacity of the hail.

[0013] Preferably, a baffle is slidably connected up and down inside the ventilation port; an elastic sealing cloth and a first expansion strip are fixedly connected between the baffle and the top side wall of the ventilation port, and the first expansion strip is located on the side of the elastic sealing cloth away from the cabinet body; a first guide hole is opened at the position of the ventilation box top near the first expansion strip; when it rains in the area where the high-voltage switchgear is located, or when the water collected inside the buffer box overflows, the water flow will run down along the surface of the cabinet body and contact the first expansion strip through the first guide hole. Then, the first expansion strip absorbs water and expands and elongates, pushing the baffle to the bottom of the ventilation port. At the same time, the elastic sealing cloth stretches and seals the ventilation port, automatically closing the ventilation port to prevent moisture and external humid air from entering the high-voltage switchgear, avoiding problems such as short circuits or corrosion damage of the internal electrical appliances. After the weather clears, the first expansion strip will gradually dry and drive the baffle to reset, reopening the ventilation port for heat dissipation.

[0014] Preferably, an inclined plate is fixedly connected between the position of the ventilation box top near the first guide hole and the cabinet body; a plurality of water diversion strips are evenly distributed on the side of the first expansion strip away from the elastic sealing cloth; the water diversion strips are made of water-absorbing materials and extend outside the ventilation port; by providing the inclined plate, it can guide the flowing water, enabling the first expansion strip to quickly contact the water. By providing a plurality of water diversion strips, the rainwater can wet the water diversion strips, and the plurality of water diversion strips guide the rainwater to various parts of the first expansion strip, making the expansion of various parts of the first expansion strip uniform and improving the utilization rate of the first expansion strip.

[0015] Preferably, a chute is provided on the side of the baffle close to the fan; a sliding plate is slidably connected inside the chute; a second expansion strip is fixedly connected between the side of the sliding plate away from the fan and the side wall of the chute; a brush is fixedly connected to the side of the sliding plate close to the fan; a second guide hole is provided at the position of the top of the baffle close to the second expansion strip; moisture will enter the chute synchronously and contact the second expansion strip, causing the second expansion strip to expand and elongate, and pushing the sliding plate outwards. Furthermore, during the up and down movement of the baffle, the surface of the fan will be wiped by the brush, removing the dust deposited on the surface of the fan blades and reducing the operating resistance of the fan. After the weather clears, the second expansion strip gradually dries and drives the sliding plate to reset, so that the brush will not affect the normal operation of the fan.

[0016] A method for using an anti-smashing high-voltage switchgear with a top buffer structure, which uses the above anti-smashing high-voltage switchgear with a top buffer structure, includes the following steps:

[0017] S1: Under normal circumstances, the ventilation opening is naturally open. When the high-voltage switchgear operates, the fan is driven by the motor to rotate, forming a flowing air current inside the cabinet body to improve the heat dissipation effect of the high-voltage switchgear.

[0018] S2: If hail falls on the top plate, the elastic layer and the spring are used to buffer the high-voltage switchgear, and the hail enters the buffer box through the collection port. After the hail melts into water, the moisture enters the inside of the water guide pipe. By making the water guide pipe in insulating contact with each electrical appliance inside the cabinet body, a water cooling function is provided for the electrical appliances, further improving the heat dissipation effect of the high-voltage switchgear.

[0019] S3: If it rains, the water flow will cause the first expansion strip to absorb water and expand and elongate, and push the baffle to the bottom of the ventilation opening. At the same time, the elastic sealing cloth elongates and seals the ventilation opening, thereby automatically closing the ventilation opening to prevent moisture and external humid air from entering the high-voltage switchgear.

[0020] The beneficial effects of the present invention are as follows:

For the anti-smashing high-voltage switchgear with a top buffer structure and its using method of the present invention, by setting a buffer box on the top of the cabinet body, hail will fall on the top plate. Using the shock-absorbing effects of the elastic layer and the spring, a buffering function is provided for the high-voltage switchgear. And by setting a ventilation box and a ventilation opening, when the high-voltage switchgear operates normally, the fan can be driven by the motor to rotate, forming a flowing air current inside the cabinet body to improve the heat dissipation effect of the high-voltage switchgear.

[0022] 2. For the anti-smashing high-voltage switch cabinet with a top buffer structure and its usage method according to the present invention, after the hail falls on the surface of the top plate, it will enter the inside of the buffer box through the collection port, thereby collecting the hail. After the hail melts into water, the water enters the inside of the water guide pipe. By making the water guide pipe in insulating contact with each electrical appliance inside the cabinet body, a water cooling function can be provided for the electrical appliances, further improving the heat dissipation effect of the high-voltage switch cabinet.

Also, due to the arc-shaped surface of the arc-shaped plate 21, the hail will not accumulate in large quantities on the upper side of the arc-shaped plate 21. When the hail hits the arc-shaped plate 21, it will drive the arc-shaped plate 21 and the guide rod 19 to move downward, and the elastic strip 20 can play a buffering effect on the arc-shaped plate 21, improving the service life of the arc-shaped plate 21.

[0039] A group of puncture needles 22 are fixedly connected to the bottom of the guide rod 19, and the multiple puncture needles 22 are fixedly connected by a connecting rod; a rubber plate 23 is fixedly connected to the bottom of the buffer box 7; a group of triangular teeth 24 are evenly distributed on the upper side of the rubber plate 23; by providing the rubber plate 23 and the triangular teeth 24, after the hail falls into the buffer box 7 through the collection port 11, it will directly hit the tips of the triangular teeth 24, facilitating the crushing of the hail. At the same time, when the guide rod 19 moves downward, it will push the hail around through the multiple puncture needles 22, increasing the storage capacity of the hail. Also, the puncture needles 22 can further crush the hail, increasing the melting speed of the hail and further increasing the storage capacity of the hail.

[0040] A baffle plate 25 is slidably connected up and down inside the ventilation opening 3; an elastic sealing cloth 26 and a first expansion strip 27 are fixedly connected between the baffle plate 25 and the top side wall of the ventilation opening 3, and the first expansion strip 27 is located on the side of the elastic sealing cloth 26 away from the cabinet body 1; a first guide hole 28 is opened at the top of the ventilation box 2 near the first expansion strip 27; when it rains in the area where the high-voltage switch cabinet is located, or when the water collected inside the buffer box 7 overflows, the water flow will drip down along the surface of the cabinet body 1 and contact the first expansion strip 27 through the first guide hole 28. Then, the first expansion strip 27 absorbs water and expands and elongates, pushing the baffle plate 25 to the bottom of the ventilation opening 3. At the same time, the elastic sealing cloth 26 stretches and seals the ventilation opening 3, which can automatically close the ventilation opening 3 to prevent moisture and external humid air from entering the high-voltage switch cabinet, avoiding problems such as short circuits or corrosion damage of internal electrical appliances. After the weather clears, the first expansion strip 27 will gradually dry and drive the baffle plate 25 to reset, so that the ventilation opening 3 is reopened for heat dissipation.

Then, during the up and down movement of the baffle plate 25, the surface of the fan 4 will be wiped by the brush 33 to remove the dust deposited on the fan blade surface, reducing the operating resistance of the fan 4.

[0044] A method for using an anti-smashing high-voltage switchgear with a top buffer structure. This method uses the above-mentioned anti-smashing high-voltage switchgear with a top buffer structure, and includes the following steps:

[0045] S1: Under normal circumstances, the ventilation opening 3 is naturally open. When the high-voltage switchgear is operating, the motor 5 drives the fan 4 to rotate, forming a flowing air current inside the cabinet body 1 to improve the heat dissipation effect of the high-voltage switchgear;

[0046] S2: If hailstones fall on the top plate 8, the elastic layer 9 and the spring 10 play a buffering effect on the high-voltage switchgear, and the hailstones enter the buffer box 7 through the collection port 11. After the hailstones melt into water, the water enters the inside of the water guide pipe 12. By making the water guide pipe 12 in insulating contact with each electrical appliance inside the cabinet body 1, a water cooling function is provided for the electrical appliances, further improving the heat dissipation effect of the high-voltage switchgear;

[0047] S3: If it rains, the water flow will cause the first expansion strip 27 to absorb water and expand and elongate, and push the baffle 25 to the bottom of the ventilation opening 3. At the same time, the elastic sealing cloth 26 is stretched and seals the ventilation opening 3, thereby automatically closing the ventilation opening 3 to prevent moisture and external humid air from entering the inside of the high-voltage switchgear.

[0048] Working principle: A buffer box 7 is arranged at the top of the cabinet body 1. Hail will fall on the top plate 8. By utilizing the shock-absorbing effects of the elastic layer 9 and the spring 10, a buffering function is achieved for the high-voltage switchgear. And by arranging a ventilation box 2 and a ventilation opening 3, when the high-voltage switchgear is operating normally, the motor 5 drives the fan 4 to rotate, forming a flowing air current inside the cabinet body 1, improving the heat dissipation effect of the high-voltage switchgear; after the hail falls on the surface of the top plate 8, it will enter the buffer box 7 through the collection port 11, thus collecting the hail. After the hail melts into water, the water enters the inside of the water guide pipe 12. By making the water guide pipe 12 in insulating contact with each electrical appliance inside the cabinet body 1, a water cooling function can be provided for the electrical appliances, further improving the heat dissipation effect of the high-voltage switchgear; when the motor 5 drives the fan 4 to rotate through the rotating shaft 6, it will synchronously drive the first bevel gear 13 and the second bevel gear 16 to rotate, and then drive the rotating rod 14 and the auger 15 to rotate, so that the water inside the water guide pipe 12 flows, forming a circulating water path, facilitating the removal of the heat of each electrical appliance inside the cabinet body 1, further improving the heat dissipation effect of the high-voltage switchgear; by arranging the first sleeve 17 and the second sleeve 18, when the hail falls on the top plate 8, the first sleeve 17 will slide inside the second sleeve 18, which can isolate the spring 10 from the hail inside the buffer box 7, avoiding the problem that the hail gets stuck inside the spring 10, resulting in the spring 10 being unable to expand and contract normally; by arranging the guide rod 19 and the arc-shaped plate 21, the arc-shaped plate 21 can block the collection port 11, avoiding the problem that the hail directly hits the bottom of the buffer box 7 through the collection port 11, resulting in the inability to achieve the buffering effect. And through the arc-shaped surface of the arc-shaped plate 21, the hail will not accumulate in large quantities on the upper side of the arc-shaped plate 21. When the hail hits the arc-shaped plate 21, it will drive the arc-shaped plate 21 and the guide rod 19 to move downward. The elastic strip 20 can play a buffering effect on the arc-shaped plate 21, improving the service life of the arc-shaped plate 21; by arranging the rubber plate 23 and the triangular teeth 24, after the hail falls into the buffer box 7 through the collection port 11, it will directly hit the tip of the triangular teeth 24, facilitating the crushing of the hail. At the same time, when the guide rod 19 moves downward, it will push the hail around through a plurality of puncture needles 22, improving the storage capacity of the hail. And the puncture needles 22 can further crush the hail, increasing the melting speed of the hail and further improving the storage capacity of the hail; when it rains in the area where the high-voltage switchgear is located, or when the water collected inside the buffer box 7 overflows, the water flow will pour down along the surface of the cabinet body 1 and contact the first expansion strip 27 through the first guide hole 28. Then the first expansion strip 27 absorbs water and expands and elongates, pushing the baffle 25 to the bottom of the ventilation opening 3. At the same time, the elastic sealing cloth 26 stretches and seals the ventilation opening 3, which can automatically close the ventilation opening 3, avoiding the problem that moisture and external humid air enter the high-voltage switchgear, resulting in short circuits or corrosion and damage of each electrical appliance inside. After the weather clears, the first expansion strip 27 will gradually dry and drive the baffle 25 to reset, making the ventilation opening 3 open for heat dissipation again;By setting the inclined plate 29, the flowing water can be guided, enabling the first expansion strip 27 to quickly come into contact with water. By setting multiple water diversion strips 30, the rainwater can wet the water diversion strips 30, and the multiple water diversion strips 30 guide the rainwater to various parts of the first expansion strip 27, making the expansion of all parts of the first expansion strip 27 uniform and improving the utilization rate of the first expansion strip 27. Water will simultaneously enter the inside of the chute and come into contact with the second expansion strip 32, prompting the second expansion strip 32 to expand and elongate, and pushing the sliding plate 31 outwards. Furthermore, when the baffle 25 moves up and down, it will wipe the surface of the fan 4 through the brush 33, removing the dust deposited on the surface of the fan blades and reducing the operating resistance of the fan 4. After the weather clears, the second expansion strip 32 gradually dries and drives the sliding plate 31 to reset, so that the brush 33 will not affect the normal operation of the fan 4.

When the high-voltage switchgear is running, the fan (4) is driven to rotate by the motor (5) to form a flowing air current inside the cabinet body (1), improving the heat dissipation effect of the high-voltage switchgear; S2: If hail falls on the top plate (8), the elastic layer (9) and the spring (10) are used to buffer the high-voltage switchgear, and the hail enters the buffer box (7) through the collection port (11). After the hail melts into water, the water enters the inside of the water guide pipe (12). By making the water guide pipe (12) in insulating contact with each electrical appliance inside the cabinet body (1), a water cooling function is provided for the electrical appliances, further improving the heat dissipation effect of the high-voltage switchgear; S3: If it rains, the water flow will cause the first expansion strip (27) to absorb water and expand and elongate, and push the baffle (25) to the bottom of the ventilation opening (3). At the same time, the elastic sealing cloth (26) is stretched and seals the ventilation opening (3), thereby automatically closing the ventilation opening (3) to prevent moisture and external humid air from entering the high-voltage switchgear.
