[0030] To make the above - mentioned objects, features and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention in conjunction with the accompanying drawings of the specification.

[0031] In the following description, many specific details are set forth to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0032] Secondly, the so - called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0033] Embodiment 1

[0034] Refer to Figures 1 - 9 , which is the first embodiment of the present invention. This embodiment provides a high - voltage switch cabinet with dust removal and heat dissipation functions. The high - voltage switch cabinet with dust removal and heat dissipation functions includes a main body assembly 100 and a heat dissipation assembly 200. Through the heat dissipation assembly 200, the situation that the inside of the cabinet body 101 is damaged due to high temperature can be avoided.

[0035] The main body assembly 100 includes a cabinet body 101.

[0036] The cabinet body 101 is used to control and protect high - voltage electrical equipment. This is prior art and will not be elaborated in this solution.

[0037] The heat dissipation component 200 is arranged on the top of the cabinet body 101 and includes a heat dissipation piece 201, a rotating piece 202 and a triggering piece 203. The heat dissipation piece 201 is arranged on the top of the cabinet body 101, the rotating piece 202 is located at the bottom of the heat dissipation piece 201, and the triggering piece 203 is arranged below the rotating piece 202.

[0038] Through the setting of the heat dissipation piece 201, when the temperature inside the cabinet body 101 is too high, the heat dissipation area of the cabinet body 101 can be increased, and the ventilation effect can be improved. In this way, the inside of the cabinet body 101 can be cooled in time, and the situation that the equipment inside the cabinet body 101 is damaged due to high temperature can be avoided. Through the setting of the rotating piece 202, it is used to drive the heat dissipation piece 201 to move, so that the heat dissipation piece 201 can increase the heat dissipation area of the cabinet body 101 and improve the ventilation effect. Through the setting of the triggering piece 203, it is used to sense the temperature inside the cabinet body 101. When the temperature inside the cabinet body 101 is too high, it can drive the rotating piece 202 to rotate, so that the rotating piece 202 can drive the heat dissipation piece 201 to move.

[0039] The dust removal component 300 is arranged on one side of the cabinet body 101 and includes a cleaning piece 301, and the cleaning piece 301 is located on the top of the cabinet body 101.

[0040] When the heat dissipation area of the cabinet body 101 increases, the dust prevention effect inside it will be reduced. Then, the top of the cabinet body 101 can be cleaned by the cleaning piece 301 to prevent dust from accumulating on the top of the cabinet body 101. Further, dust cannot enter the inside of the cabinet body 101, so as to avoid dust accumulating on electrical components and insulating materials, increasing the risk of electric leakage and fire.

[0041] The driving component 400 is arranged on one side of the cabinet body 101 and includes an air storage tank 401, an air outlet pipe 402, a first blocking piece 403, a second blocking piece 404 and a pushing piece 405. The air storage tank 401 is fixed on one side of the cabinet body 101, the air outlet pipe 402 is fixed on the top of the air storage tank 401, the first blocking piece 403 is located inside the air outlet pipe 402, the second blocking piece 404 is arranged inside the air outlet pipe 402, and the pushing piece 405 is arranged on the air outlet pipe 402.

[0042] The air storage tank 401 is used to store high-pressure gas, and the air outlet pipe 402 is used to discharge the gas to the outside and transport it to the inside of the heat dissipation piece 201, so as to improve the heat dissipation effect of the heat dissipation piece 201 on the cabinet body 101. Both the first blocking piece 403 and the second blocking piece 404 are used to separately block the gas inside the air storage tank 401 to avoid unnecessary waste of the gas inside it. Through the setting of the pushing piece 405, it is used to push the first blocking piece 403 and the second blocking piece 404 to move, so that the two can be opened, and then the gas can be discharged to the outside.

[0043] Embodiment 2

[0044] Reference Figures 1 - 9 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0045] Specifically, the heat dissipation member 201 includes a ventilation frame 201a, an adjustment plate 201b, a support frame 201c, and fan blades 201d. The ventilation frame 201a is fixed to the top of the cabinet body 101. The adjustment plate 201b is located inside the ventilation frame 201a. The support frame 201c is located above the cabinet body 101. The fan blades 201d are arranged inside the support frame 201c.

[0046] A plurality of ventilation holes are formed in both the ventilation frame 201a and the adjustment plate 201b. The plurality of ventilation holes are linearly and evenly distributed on the ventilation frame 201a and the adjustment plate 201b. When the temperature inside the cabinet body 101 is normal, the solid part of the adjustment plate 201b will block the ventilation holes on the ventilation frame 201a. At this time, only a small amount of air can circulate, thereby dust-proofing the inside of the cabinet body 101 and avoiding the situation that a large amount of dust enters the inside of the cabinet body 101. When the temperature inside the cabinet body 101 is too high, the adjustment plate 201b will move to one side, so that the ventilation holes on the adjustment plate 201b coincide with the ventilation holes on the ventilation frame 201a, thereby increasing the heat dissipation area of the cabinet body 101 and improving the ventilation effect, thus avoiding the situation that the temperature inside the cabinet body 101 is too high and causing damage to the internal equipment.

[0047] The support frame 201c is fixed to the top of the cabinet body 101 through support legs. The number of the fan blades 201d is multiple, and they are annularly and evenly distributed inside the support frame 201c. When the fan blades 201d rotate, the efficiency of discharging the heat inside the cabinet body 101 to the outside can be further improved, and thus the heat dissipation efficiency of the cabinet body 101 can be improved.

[0048] A force-bearing plate is fixed to the end of the fan blade 201d. An annular groove is formed inside the support frame 201c. The force-bearing plate is movably connected to the annular groove. One end of the air outlet pipe 402 is communicated with the inside of the support frame 201c. When the gas inside the air storage tank 401 enters the annular groove through the air outlet pipe 402, the force-bearing plate can be pushed to move, and the fan blade 201d can be driven to rotate through the force-bearing plate, thereby enabling the fan blade 201d to improve the efficiency of discharging the heat inside the cabinet body 101 to the outside.

[0049] Specifically, the rotating member 202 includes a fixed sleeve 202a, a rotating sleeve 202b, a movable column 202c, a fixed shaft 202d, a rotating block 202e, and a connecting shaft 202f. The fixed sleeve 202a is fixed to the bottom of the ventilation frame 201a. The rotating sleeve 202b is rotatably connected within the fixed sleeve 202a. The movable column 202c is inserted into the rotating sleeve 202b. The fixed shaft 202d is fixed to one side of the movable column 202c. A spiral groove 202b-1 is formed within the rotating sleeve 202b. One side of the rotating block 202e is fixed to the rotating sleeve 202b. The connecting shaft 202f is fixed to the bottom of the adjusting plate 201b.

[0050] The rotating sleeve 202b is rotatably connected within the fixed sleeve 202a through a bearing. The fixed shaft 202d slides within the spiral groove 202b-1. A sliding groove is formed on the rotating block 202e. The connecting shaft 202f is movably connected within the sliding groove. An arc-shaped groove is formed on the fixed sleeve 202a. The rotating block 202e is movably connected within the arc-shaped groove.

[0051] When the movable column 202c moves upward, it will drive the fixed shaft 202d to slide within the spiral groove 202b-1. Through the cooperation of the two, the rotating sleeve 202b can be driven to rotate, causing the rotating sleeve 202b to drive the rotating block 202e to rotate, and driving the connecting shaft 202f to move through the rotating block 202e, so that the connecting shaft 202f drives the adjusting plate 201b to move, thereby increasing the heat dissipation area of the cabinet body 101 and improving the ventilation effect.

[0052] Specifically, the triggering member 203 includes a support sleeve 203a, an expansion block 203b, a movable plate 203c, and a first spring 203d. The support sleeve 203a is fixed to the bottom of the fixed sleeve 202a. The expansion block 203b is located within the support sleeve 203a. The movable plate 203c is fixed to the bottom end of the movable column 202c. Both ends of the first spring 203d are fixed to the movable plate 203c and the inner top wall of the support sleeve 203a respectively.

[0053] The support sleeve 203a has a heat conduction effect. The expansion block 203b has the property of thermal expansion and contraction. When the temperature inside the cabinet body 101 is too high, the support sleeve 203a will transfer heat to the expansion block 203b. At this time, the expansion block 203b will expand and push the movable plate 203c to move, thereby enabling the movable plate 203c to drive the movable column 202c to move upward. When the temperature inside the cabinet body 101 drops, the expansion block 203b will shrink, and at this time, the movable plate 203c and the movable column 202c are pushed back to their original positions by the first spring 203d.

[0054] Specifically, the cleaning member 301 includes a cleaning plate 301a, a connecting block 301b, a reciprocating roller 301c, and a positioning shaft 301d. The cleaning plate 301a is located at the top of the cabinet body 101. One side of the connecting block 301b is fixed to the cleaning plate 301a. The reciprocating roller 301c is inserted into the connecting block 301b, and the positioning shaft 301d is fixed in the connecting block 301b.

[0055] There are two connecting blocks 301b, which are respectively fixed on both sides of the cleaning plate 301a. Support blocks are fixed at the four corners of the top of the cabinet body 101. The reciprocating roller 301c is rotatably connected to the support blocks through bearings. The positioning shaft 301d is meshed with the inside of the reciprocating roller 301c. When the heat dissipation area of the cabinet body 101 increases, the reciprocating roller 301c will rotate. Through the cooperation of the positioning shaft 301d, it will drive the connecting block 301b to move, and drive the cleaning plate 301a to move through the connecting block 301b, so as to clean the top of the cabinet body 101 by the cleaning plate 301a, avoiding the situation that the increase of the heat dissipation area will cause dust to enter the interior of the cabinet body 101.

[0056] A stabilizing column is fixed between the two support blocks on the other side of the top of the cabinet body 101. The stabilizing column is movably connected to the inside of the connecting block 301b, and is used to position the cleaning plate 301a through the cooperation of the two, avoiding the situation that the cleaning plate 301a will shift when moving.

[0057] A sealing sleeve is fixed on one side of the support block. A plurality of rotating plates are fixed on the outer side of the end of the reciprocating roller 301c. The plurality of rotating plates are evenly distributed in a ring on the outer side of the reciprocating roller 301c and are located inside the sealing sleeve. A connecting pipe is fixed on one side of the sealing sleeve. The other end of the connecting pipe is communicated with the air outlet pipe 402. The bottom of the sealing sleeve is communicated with an exhaust pipe. The bottom end of the exhaust pipe penetrates into the cabinet body 101. When the gas inside the air storage tank 401 enters the inside of the air outlet pipe 402, the gas will be conveyed into the inside of the sealing sleeve through the exhaust pipe and blow the rotating plates to rotate, so as to drive the reciprocating roller 301c to rotate by the rotating plates. When the gas blows the rotating plates to move in the sealing sleeve, it will enter the cabinet body 101 through the exhaust pipe. At this time, the efficiency of the air flow inside the cabinet body 101 can be increased, and thus the heat dissipation effect of the cabinet body 101 can be improved.

[0058] Specifically, the first blocking member 403 includes a fixing ring 403a and a blocking plate 403b. The fixing ring 403a is fixed inside the air outlet pipe 402, and the blocking plate 403b is located at the bottom of the fixing ring 403a.

[0059] The inside of the air outlet pipe 402 is blocked by the blocking plate 403b, so as to avoid the continuous leakage of the gas inside the air storage tank 401 when the temperature inside the cabinet body 101 is normal, thus causing the waste of gas. When the blocking plate 403b moves downward, the blocking of the gas can be released, and then the gas can enter the inside of the sealing sleeve through the connecting pipe.

[0060] A stabilizing rod is fixed to the bottom of the plugging plate 403b, and a stabilizing frame is fixed inside the air outlet pipe 402. The stabilizing rod is movably connected inside the stabilizing frame, and the two cooperate to position the plugging plate 403b to prevent the plugging plate 403b from shifting. A fourth spring is fixed to the top of the stabilizing frame, and the fourth spring is used to apply a thrust to the plugging plate 403b to make the plugging plate 403b fit more tightly with the fixing ring 403a.

[0061] Embodiment 3

[0062] Refer to Figures 1 - 9 , which is the third embodiment of the present invention, and this embodiment is based on the first two embodiments.

[0063] Specifically, the second plugging member 404 includes a positioning plate 404a, a baffle plate 404b, and a hinge plate 404c. The positioning plate 404a is fixed inside the air outlet pipe 402, the baffle plate 404b is located on top of the positioning plate 404a, and the hinge plate 404c is fixed to the top of the positioning plate 404a.

[0064] A fixing block is fixed to the top of the baffle plate 404b. A rotating shaft is movably connected inside the hinge plate 404c, and the fixing block is fixed to the rotating shaft. The baffle plate 404b is hinged to the positioning plate 404a through the cooperation of the hinge plate 404c and the fixing block. An exhaust hole is provided on the positioning plate 404a, and the baffle plate 404b is used to plug the exhaust hole.

[0065] When the temperature inside the cabinet 101 is not too high, at this time, the gas will only enter the connecting pipe and will not enter the support frame 201c. By increasing the heat dissipation area of the cabinet 101, the heat dissipation effect of the cabinet 101 can be satisfied, and the rotation of the fan blade 201d is not required, thereby reducing the consumption of gas.

[0066] When the temperature inside the cabinet 101 is too high and the heat dissipation of the cabinet 101 cannot be satisfied only by increasing the heat dissipation area, at this time, the baffle plate 404b will open upward, and the gas will enter the support frame 201c, thereby driving the fan blade 201d to rotate, so as to further improve the heat dissipation effect of the cabinet 101.

[0067] A torsion spring is arranged on the outer side of the rotating shaft on the hinge plate 404c, and both ends of the torsion spring are fixed to the rotating shaft and the hinge plate 404c respectively. When the plugging plate 403b fits with the fixing ring 403a and the gas flow inside the air outlet pipe 402 stops, at this time, a downward torsional force is applied to the baffle plate 404b through the torsion spring, so that the baffle plate 404b fits with the positioning plate 404a again.

[0068] Specifically, the second plugging member 404 further includes a limiting rod 404d and a positioning frame 404e. The limiting rod 404d is inserted into the air outlet pipe 402, and the positioning frame 404e is fixed to one side of the air outlet pipe 402.

[0069] The end of the limit rod 404d is inclined. The limit rod 404d is movably connected inside the positioning frame 404e. The positioning frame 404e positions the limit rod 404d to prevent the limit rod 404d from shifting when moving. The limit rod 404d contacts the top of the baffle 404b to restrict the baffle 404b and prevent the baffle 404b from opening when pushed by gas. When the baffle 404b is extruded and moves outward from the outlet pipe 402 and separates from the top of the baffle 404b, the restriction on the baffle 404b can be released, and then the baffle 404b can be pushed by the air pressure and thus opened.

[0070] A first stabilizing block is fixed to the top of the limit rod 404d, and a second stabilizing block is fixed to the top of the positioning frame 404e. A fifth spring is fixed between the first stabilizing block and the second stabilizing block. After the limit rod 404d is released from the restriction, the fifth spring applies a pulling force to the first stabilizing block, and the first stabilizing block drives the limit rod 404d to move, causing the limit rod 404d to move into the outlet pipe 402 and restrict the baffle 404b again. The elastic force of the torsion spring is greater than the elastic force of the fifth spring.

[0071] Specifically, the pushing member 405 includes a push rod 405a, a pressing rod 405b, a pressing block 405c, and a connecting rod 405d. The push rod 405a is located on the top of the blocking plate 403b. The pressing rod 405b is located on one side of the push rod 405a. The pressing block 405c is located at one end of the pressing rod 405b. The connecting rod 405d is fixed to the bottom of the pressing block 405c.

[0072] A stabilizing frame is fixed inside the outlet pipe 402. The push rod 405a is movably connected inside the stabilizing frame to position the push rod 405a. The top of the push rod 405a is inclined. One end of the pressing rod 405b penetrates into the cabinet body 101 and is movably connected to the cabinet body 101. A plurality of positioning sleeves are fixed to the bottom of the ventilation frame 201a. The pressing rod 405b is movably connected inside the positioning sleeves to support and position the pressing rod 405b. One side of the pressing block 405c is inclined. The connecting rod 405d is L-shaped and one end is fixed to the movable plate 203c.

[0073] When the movable plate 203c moves upward, it will simultaneously drive the connecting rod 405d and the pressing block 405c to move upward, and the inclined surface of the pressing block 405c squeezes the pressing rod 405b to push the pressing rod 405b to move, and the pressing rod 405b squeezes the inclined surface at the top of the push rod 405a, so that the push rod 405a can move downward, and the push rod 405a pushes the blocking plate 403b to move downward, thereby releasing the restriction on the gas inside the gas storage tank 401, and then the gas can flow in the outlet pipe 402.

[0074] Specifically, the pusher 405 further includes a rotating rod 405e, a pushing block 405f, a stress block 405g, and a support plate 405h. The rotating rod 405e is located on one side of the air outlet pipe 402. The pushing block 405f is fixed to the top of the extrusion rod 405b. The stress block 405g is fixed to the bottom of the limiting rod 404d. The support plate 405h is fixed to one side of the air outlet pipe 402.

[0075] The center of the rotating rod 405e is rotationally connected to the inside of the support plate 405h through a rotating shaft. When the extrusion rod 405b moves, it will drive the pushing block 405f to move simultaneously. As the temperature inside the cabinet 101 continues to rise, the expansion block 203b will continue to expand and push the movable plate 203c to move upward continuously. In this way, the extrusion block 405c can push the extrusion rod 405b to move a larger stroke, and make the pushing block 405f contact the bottom end of the rotating rod 405e, and push the bottom end of the rotating rod 405e to move. In this way, the other end of the rotating rod 405e can push the stress block 405g to move, and drive the limiting rod 404d to move through the stress block 405g. In this way, the limiting rod 404d can be separated from the top of the baffle 404b, and thus the restriction on the baffle 404b can be released.

[0076] During use, when the temperature inside the cabinet 101 is too high, the support sleeve 203a will transfer the expansion block 203b to the expansion block 203b. At this time, the expansion block 203b will expand and push the movable plate 203c to move through the expansion block 203b, so that the movable plate 203c drives the movable column 202c to move upward. When the movable column 202c moves upward, it will drive the fixed shaft 202d to slide in the spiral groove 202b-1. Through the cooperation of the two, the rotating sleeve 202b can be driven to rotate, so that the rotating sleeve 202b drives the rotating block 202e to rotate, and drives the connecting shaft 202f to move through the rotating block 202e, so that the connecting shaft 202f drives the adjusting plate 201b to move, and makes the air holes on the adjusting plate 201b coincide with the air holes on the air permeable frame 201a. In this way, the heat dissipation area of the cabinet 101 can be increased, the ventilation effect can be improved, and thus the situation that the internal temperature of the cabinet 101 is too high and the internal equipment will be damaged can be avoided.

[0077] When the movable plate 203c moves upward, it will drive the connecting rod 405d and the extrusion block 405c to move upward simultaneously, and extrude the extrusion rod 405b through the inclined surface of the extrusion block 405c, so as to push the extrusion rod 405b to move, and the extrusion rod 405b extrudes the inclined surface at the top of the push rod 405a, so that the push rod 405a can move downward, and the push rod 405a pushes the blocking plate 403b to move downward, so as to release the restriction on the gas inside the gas storage tank 401, and further enable the gas to flow in the air outlet pipe 402.

[0078] When the gas inside the gas storage tank 401 enters the inside of the air outlet pipe 402, it will transport the gas to the inside of the sealing sleeve through the exhaust pipe and blow the rotating plate to rotate. In this way, the rotating plate can drive the reciprocating roller 301c to rotate. Through the cooperation of the positioning shaft 301d, it will drive the connecting block 301b to move, and drive the cleaning plate 301a to move through the connecting block 301b. In this way, the cleaning plate 301a can clean the top of the cabinet body 101, avoiding the situation that dust enters the inside of the cabinet body 101 due to the increase of the heat dissipation area. At the same time, after the gas blows the rotating plate to move in the sealing sleeve, it will enter the cabinet body 101 through the exhaust pipe. At this time, the efficiency of air flow inside the cabinet body 101 can be increased, and then the heat dissipation effect of the cabinet body 101 can be improved.

[0079] As the temperature inside the cabinet body 101 continues to rise, the expansion block 203b will continue to expand and push the movable plate 203c to move upward continuously. In this way, the extrusion block 405c can push the extrusion rod 405b to move a larger stroke, and make the push block 405f contact the bottom end of the rotating rod 405e and push the bottom end of the rotating rod 405e to move. In this way, the other end of the rotating rod 405e can push the force-bearing block 405g to move, and drive the limit rod 404d to move through the force-bearing block 405g. In this way, the limit rod 404d can be separated from the top of the baffle 404b, thereby releasing the restriction on the baffle 404b, and the baffle 404b is pushed upward to open by the gas, so that the gas enters the support frame 201c, pushes the force-bearing plate to move, and drives the fan blade 201d to rotate through the force-bearing plate. When the fan blade 201d is rotating, the efficiency of discharging the heat inside the cabinet body 101 to the outside can be further improved, and then the heat dissipation efficiency of the cabinet body 101 can be improved.
