Description

Technical Field

[0001] The present invention relates to the technical field of insulating equipment, and in particular to an insulating power equipment box. Background Art

[0002] An insulated power equipment box is a box made of insulating material used to accommodate and protect power equipment. It can effectively prevent current leakage, prevent electric shock accidents and has certain protective properties.

[0003] Existing devices of this type suffer from unsatisfactory insulation effects. For example, Chinese Patent Publication No. "CN109904757B" discloses a shock-absorbing box for electric equipment. This device uses a vertical elastic component and front and rear elastic components to provide shock absorption for the device. The vertical elastic component uses a shock-absorbing spring to provide shock absorption in the vertical direction of the device. However, the spring is generally made of metal. Although the device separates the inner box from the outer box, the shock-absorbing spring is still at the bottom of the inner box, connecting the inner box and the outer box. When the device leaks or shorts, the current can be transferred from the shock-absorbing spring to the outer box of the device, which makes the device's insulation effect unsatisfactory. Accordingly, the present application proposes an insulated electric equipment box. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an insulating power equipment box.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: An insulated power equipment box includes a heat dissipation assembly and a shock-absorbing insulation assembly. The heat dissipation assembly consists of a housing, an air inlet pipe, a fan motor, a pulley, a transmission belt, a half gear, a heat dissipation box, a rack, a piston, a spring rod, heat dissipation fins, and a fan. The heat dissipation assembly is used to dissipate heat for the device. The housing is fixedly connected to the heat dissipation box. The insulation component is composed of a sealing base, a sealing side plate, a compressed gas tank, a connecting pipe, a pneumatic rod, a mounting plate, and a shock-absorbing tube. The insulation component is used for the insulation of electrical equipment. The pneumatic rod is fixedly connected to the sealing side plate, and the compressed gas tank is fixedly connected to the sealing side plate.

[0006] Preferably, a connecting pipe is fixedly connected between the two heat dissipation boxes, the water inlet end of the piston is connected to the heat dissipation box without an air inlet pipe, and the water outlet end of the piston is connected to the heat dissipation box with an air inlet pipe.

[0007] Preferably, the fan motor is connected to the top of the inner wall of the casing, and the number of the pulleys and transmission belts is two pairs, one pair of the pulleys and transmission belts connects the output shaft of the fan motor to the half gear, the half gear is engaged with the rack, and the rack is slidably connected to the center of the spring rod.

[0008] Preferably, the sealing side plate is slidingly and sealingly connected to the sealing base, a limit plate is fixedly connected to the side wall of the sealing side plate, a glass tube is fixedly connected inside the limit plate, a limit pin is placed on the glass tube, and the limit pin is inserted into the inside of the pneumatic rod.

[0009] Preferably, a vent pipe is fixedly connected to the interior of the pneumatic rod, and a sealing plug is sealedly connected to the interior of the vent pipe.

[0010] Preferably, a reciprocating screw is rotatably connected inside the housing, and the reciprocating screw is fixedly connected to one of the pulleys.

[0011] Preferably, there are two heat dissipation boxes, one of which is fixedly connected to the inner wall of the air inlet pipe, and the internal heat dissipation fins of the other heat dissipation box extend to the outside. The heat dissipation box is used to hold coolant, and a wiper is threadedly connected to the reciprocating screw.

[0012] The present invention has the following beneficial effects: 1. By setting up a heat dissipation component, the device can dissipate heat for the electrical equipment inside the device when in use, making the electrical equipment inside the device more stable during operation. When the device is running, the fan can draw the air cooled by the heat dissipation box into the outer casing, thereby completing the heat dissipation of the electrical equipment, so as to achieve the effect of making the electrical equipment more stable.

[0013] 2. By setting up a sealed base, the device can provide a shock-absorbing effect on the sealed side panels when working, avoiding the phenomenon of vibration damaging the equipment. During operation, the liquid used for heat dissipation can enter the interior of the sealed base, prop up the sealed side panels, and raise them. When subjected to vibration, the liquid can provide a shock-absorbing effect.

[0014] 3. By setting up a pneumatic rod and a compressed gas tank, when a short circuit occurs in the device, the carbon dioxide gas in the compressed gas tank can be released, thereby extinguishing the arc inside the device. At the same time, the pneumatic rod will push the electrical equipment located on the mounting plate deeper into the outer casing of the device, utilizing the insulating and arc-extinguishing properties of carbon dioxide to provide further insulation for the device.

[0015] 4. By setting up a wiper, the device can wipe off moisture and dust on the inner wall of the device when in use, which can further improve the safety and insulation of the device. In summer or when the environment is relatively humid, the inner wall of the device is more prone to condensation or water droplets caused by moisture accumulation. The wiper can wipe off these water droplets, thereby making the operation of the electrical equipment in the device safer. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Example 1, reference Figure 1 as well as Figure 6-8, an insulated power equipment box, including a heat dissipation component and a shock-absorbing insulation component, the heat dissipation component consists of a shell 1, an air inlet pipe 4, a fan motor 8, a pulley 24, a transmission belt 25, a half gear 5, a heat dissipation box 3, a rack 9, a piston 6, a spring rod 10, a heat dissipation fin 12, and a fan 16. The fan motor 8 is connected to the top of the inner wall of the shell 1. The heat dissipation component is used for heat dissipation of the device. The shell 1 is fixedly connected to the heat dissipation box 3, the rack 9 is slidingly connected to the center of the spring rod 10, and the number of pulleys 24 and transmission belts 25 is two pairs, one pair of pulleys 24 and transmission belts 25 connects the output shaft of the fan motor 8 to the half gear 5, and the half gear 5 is meshed with the rack 9. The internal rotation of the shell 1 is connected to a reciprocating screw 2, and the reciprocating screw 2 is threaded with a wiper 7.

[0020] In this embodiment, the two heat dissipation boxes 3 are used to store coolant. Figure 1 The heat sink 3 connected to the air inlet pipe 4 will suck the coolant from one heat sink 3 into the other heat sink 3 through the piston 6. When the device starts working, the fan motor 8 will rotate and drive the two pulleys 24 on its output shaft to rotate. The rotation of the pulley 24 will transmit power to the other two pulleys 24 through the transmission belt 25. One of the pulleys can drive the half gear 5 to rotate. Since the half gear 5 is engaged with the rack 9, the half gear 5 will make the rack 9 move. Because only a part of the half gear 5 has teeth, the rack 9 will move intermittently. The rack 9 is connected to the output rod of the piston 6, so the movement of the rack 9 will allow the piston 6 to continuously pump the coolant into the heat sink 3 with the air inlet pipe 4.

[0021] Furthermore, the rotation of the output shaft of the fan motor 8 will drive the rotation of the fan 16, and the air inlet pipe 4 connects the internal space of the shell 1 with the outside world, and the connection point is located behind the fan 16, that is, the air suction point of the fan 16. When the coolant is pumped into the heat dissipation box 3 with the air inlet pipe 4, due to the limited internal space of the heat dissipation box 3, another part of the coolant will flow back into the heat dissipation box 3 without the air inlet pipe 4 through the connecting pipe 11, thereby completing the circulation of the coolant. During this period, due to the suction of the fan 16, the outside air will enter the interior of the device, and the heat will be absorbed by the coolant in the air inlet pipe 4. After entering the device, the temperature of the air will become lower, thereby lowering the internal temperature of the device. Example 2:

[0022] Different from the first embodiment, this embodiment further includes the following contents: There are two heat dissipation boxes 3, one of which is fixedly connected to the inner wall of the air inlet pipe 4, and the internal heat dissipation fins 12 of the other heat dissipation box 3 extend to the outside, the reciprocating screw 2 is fixedly connected to one of the pulleys 24, the heat dissipation box 3 is used to store coolant, and a wiper block 7 is threadedly connected to the reciprocating screw 2. A connecting pipe 11 is fixedly connected between the two heat dissipation boxes 3, the water outlet end of the piston 6 is connected to the heat dissipation box 3 with the air inlet pipe 4, and the water inlet end of the piston 6 is connected to the heat dissipation box 3 without the air inlet pipe 4.

[0023] In this embodiment, there is a groove on the upper surface of the housing 1. The specific position is as follows: Figure 6 , which is located below the exposed portion of the heat sink 12. In actual use, due to the limited space inside the housing 1, the air in the device will be discharged from the slot to the outside and blown to the exposed heat sink 12, that is, Figure 1 The heat dissipation box 3 connected to the heat dissipation fins 12 is used to cool the coolant. When the air from the inside of the device blows toward the heat dissipation fins 12 exposed to the outside, the heat between the heat dissipation fins 12 can be taken away to avoid heat accumulation between the heat dissipation fins 12, thereby further improving the heat dissipation effect of the device.

[0024] Furthermore, the connecting pipe 11 connects the tail ends of the two heat sinks 3, and the water inlet and outlet ends of the piston 6 are connected to the heads of the two heat sinks 3. When the coolant flows, it is sucked into the head of the heat sink 3 without the air inlet pipe 4 through the water inlet end of the piston 6, and enters the heat sink 3 with the air inlet pipe 4 from the water outlet end of the piston 6. During this period, the coolant will pass through the multiple exposed heat sink fins 12 from the inside of the heat sink 3, which can further enhance the heat dissipation effect.

[0025] Furthermore, the reciprocating screw 2 can be rotated by the pulley 24. When the reciprocating screw 2 rotates, the wiping block 7 will move and wipe up and down along the inner wall of the device. Due to the particularity of the reciprocating screw 2, the wiping block 7 will move up and down to complete the wiping of the inner wall of the device. Example 3:

[0026] Different from the first and second embodiments, this embodiment also has the following further contents: The insulation component is composed of a sealing base 17, a sealing side plate 13, a compressed gas tank 14, a connecting pipe 15, a pneumatic rod 18, a mounting plate 19, and a shock-absorbing tube 21. The insulation component is used for the insulation of electrical equipment. The pneumatic rod 18 is fixedly connected to the sealing side plate 13, and the sealing side plate 13 is slidingly and sealingly connected to the sealing base 17. A limiting plate 20 is fixedly connected to the side wall of the sealing side plate 13.

[0027] The compressed gas tank 14 is fixedly connected to the sealing side plate 13, a glass tube 27 is fixedly connected to the limit plate 20, a limit pin 22 is placed on the glass tube 27, the limit pin 22 is inserted into the inside of the pneumatic rod 18, a sealing plug 26 is sealed in the vent pipe 23, and the inside of the pneumatic rod 18 is fixedly connected to the vent pipe 23.

[0028] In this embodiment, the output rod of the pneumatic rod 18 is supported by insulating material, the mounting plate 19 is used to install electrical equipment, and the glass tube 27 is a prior art technology commonly used in fire sprinklers. The glass tube 27 is filled with a thermosensitive liquid, which expands when heated, breaking the glass tube 27 and allowing the limit pin 22 to fall under the action of gravity.

[0029] Furthermore, the limit pin 22 is located above the glass tube 27. When the glass tube 27 breaks, the limit pin 22 will fall under the action of gravity, which will release the limit pin 22 from limiting the output rod of the pneumatic rod 18 and allow the output rod of the pneumatic rod 18 to move toward the inside of the device.

[0030] For further reference, Figure 5 , the interior of the pneumatic rod 18 is as follows Figure 5 As shown, its output rod is limited by the limit pin 22 and cannot be fully extended. When a short circuit occurs in the electrical equipment within the device, the limit pin 22 falls, so the output rod of the pneumatic rod 18 can move. When the output rod of the pneumatic rod 18 moves, it will pull the sealing plug 26 toward the inside of the device. There is a gap on the vent pipe 23. When the sealing plug 26 passes through the gap as it moves, the carbon dioxide inside it can be ejected from the gap, thereby achieving the effect of using carbon dioxide to produce arc extinguishing.

[0031] Furthermore, when a short circuit occurs in the device, the output shaft of the pneumatic rod 18 will be moved by the interior of the device, thereby driving the mounting plate 19 to move deeper into the interior of the device, that is, deeper into the carbon dioxide. Since carbon dioxide has good insulation properties, this can further enhance the insulation performance of the device.

[0032] Furthermore, the shock-absorbing tube 21 is connected to the sealing base 17, and there is a one-way valve at the connection. Before using the device, the interior of the sealing base 17 needs to be filled with coolant so that the device can withstand a certain degree of vibration.

[0033] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
