Description

Technical Field

[0001] This utility model relates to the field of shielding technology, specifically a high-voltage equipment shielding cover with integrated heat dissipation holes. Background Technology

[0002] As a key protective component in power systems, the shielding cover of high-voltage equipment has the core function of forming an electromagnetic shielding barrier through a metal shell or mesh cover to prevent external electric and magnetic fields from interfering with the internal equipment, while also preventing the electromagnetic fields generated by the internal high-voltage components from radiating outward, thus ensuring the stability of equipment operation and the safety of operators.

[0003] According to Chinese Patent CN216491707U, a shielding cover for high-voltage electrical equipment with a heat dissipation and cooling structure is disclosed. The cover comprises a rectangular base with an internal cavity and a fixing mechanism; ventilation holes located at the upper end of the base, the ventilation holes being square through-holes with a ventilation mechanism; and a motor housing located on the side of the base, welded to it. This shielding cover for high-voltage electrical equipment with a heat dissipation and cooling structure is equipped with a ventilation and heat dissipation mechanism, enabling rapid heat dissipation and cooling of the interior of the base. Simply operate the controller to start the second motor at the upper end of the connecting frame at the bottom of the base. The second motor starts and drives the fan blades to rotate, generating airflow to cool the interior of the base. Simultaneously, the ventilation holes on the surface of the base increase airflow, allowing the electronic components inside the base to cool down rapidly.

[0004] The dust filter in the aforementioned device can become clogged after prolonged use, leading to reduced ventilation and impaired heat dissipation. However, cleaning requires disassembling the entire structure, which is cumbersome. Therefore, we provide a high-voltage equipment shielding cover with integrated heat dissipation holes. Utility Model Content

[0005] The purpose of this invention is to provide a high-voltage equipment shielding cover with integrated heat dissipation holes to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-voltage equipment shielding cover with integrated heat dissipation holes, comprising: a substrate;

[0007] Heat dissipation holes are formed on the front side of the substrate;

[0008] And an operating component fixedly connected to the surface of the substrate; the operating component includes a dustproof part fixedly connected to the surface of the substrate, the dustproof part being connected to a heat dissipation part, and a protective part being provided in front of the heat dissipation part.

[0009] Preferably, the dustproof part includes a vent on the front of the base, an installation groove on the inner side of the vent, an installation plate on the inner surface of the installation groove, a dustproof net fixedly connected to the side of the installation plate, the outer surface of the dustproof net being snapped onto the inner surface of the vent, a shaft rotatably connected to the inner surface of the installation groove via a bearing, the front end of the shaft penetrating the back of the installation plate, a movable groove on the inner surface of the shaft, a locking block fixedly connected to the inner surface of the movable groove via an elastic sheet, the outer end of the locking block being snapped onto the inner surface of a slot on the inner surface of the installation plate, and an adjusting spring fixedly connected to the side of the elastic sheet away from the locking block.

[0010] Preferably, the heat dissipation unit includes a drive motor fixedly connected to the inner side of the back of the base. The output end of the drive motor is fixedly connected to a main shaft. A fan blade is fixedly connected to the outer wall of the front end of the main shaft. A transmission gear is fixedly connected to the outer wall of the main shaft. A linkage gear meshes with the side of the transmission gear. A secondary shaft is fixedly connected to the inner wall of the linkage gear. A fan blade is fixedly connected to the outer wall of the front end of the secondary shaft. The rear end of the secondary shaft is rotatably connected to the inner side of the back of the base through a bearing.

[0011] Preferably, the protective part includes a protective plate inserted into the inner surface of the substrate, a slider fixedly connected to the side of the protective plate, the outer end of the slider penetrating the inner surface of the slot, an upper baffle fixedly connected to the top of the slider, a lower baffle fixedly connected to the bottom of the slider, a telescopic rod fixedly connected to the bottom of the slider, the bottom of the telescopic rod fixedly connected to the top of the connecting block, and one side of the connecting block fixedly connected to the side of the substrate.

[0012] Preferably, the number of elastic pieces is set to four, with each pair of the four elastic pieces forming a group, and each pair is fixedly connected to the inner end face of the card block. The elastic pieces are arc-shaped to provide elastic support for the card block, ensuring that the card block fits tightly with the card slot and avoiding loosening or tilting caused by unilateral force.

[0013] Preferably, the outer surface of the slider is slidably connected to the inner surface of the slot to ensure that the slider drives the protective plate to rise and fall smoothly.

[0014] Preferably, the positions of the upper baffle and the lower baffle correspond to the positions of the slot and slide in contact with the outside of the base. The upper baffle and the lower baffle can block the gap between the slot and the slider, reducing the amount of rainwater and dust that seeps into the equipment through the slot.

[0015] Compared with the prior art, this utility model provides a high-voltage equipment shielding cover with integrated heat dissipation holes, which has the following beneficial effects:

[0016] 1. This high-voltage equipment shielding cover with integrated heat dissipation holes is designed so that the dustproof mesh is aligned and snapped into the ventilation opening on the front of the base, while the mounting plate is snapped into the mounting groove. After the shaft passes through the back of the mounting plate, the elastic plate in the movable groove pushes the locking block into the slot of the mounting plate, thus fixing the dustproof mesh. The dustproof mesh prevents dust from entering the base during heat dissipation. By rotating the shaft, the locking block is squeezed and retracts into the movable groove, which in turn causes the elastic plate to retract, disengaging the locking block from the slot. At this point, the mounting plate can be pulled out to remove the dustproof mesh. After cleaning, it can be reinstalled, thus achieving quick disassembly of the dustproof mesh.

[0017] 2. The high-voltage equipment shield with integrated heat dissipation holes drives the main shaft to rotate after the drive motor is powered on. The main shaft meshes with the linkage gear through the transmission gear, which in turn drives the auxiliary shaft to rotate synchronously. At this time, the fan blades on the main shaft and the auxiliary shaft rotate simultaneously to generate directional airflow, which dissipates heat through the heat dissipation holes, thereby achieving rapid heat dissipation.

[0018] 3. The high-voltage equipment shielding cover with integrated heat dissipation holes uses a telescopic rod to control the slider to slide up and down in the slot, thereby controlling the protective plate to slide up and down in the base, thus controlling the opening or closing of the heat dissipation holes. When it is open, heat dissipation can be carried out. At the same time, the opening and closing degree of the protective plate can be adjusted according to the heat dissipation requirements. When the slider moves up and down, the upper baffle and lower baffle can be used to cover the gap between the slot and the slider, reducing the amount of rainwater and dust that seeps into the equipment through the slot.

[0028] Example 1: The high-voltage equipment shielding cover with integrated heat dissipation holes provided by this utility model, such as... Figures 1 to 6 As shown: A high-voltage equipment shield with integrated heat dissipation holes, comprising: a substrate 1;

[0029] Heat dissipation holes 3 are provided on the front side of the substrate 1;

[0030] And an operating component 2 fixedly connected to the surface of the substrate 1; the operating component 2 includes a dustproof part 21 fixedly connected to the surface of the substrate 1, the dustproof part 21 is connected to a heat dissipation part 22, and a protective part 23 is provided in front of the heat dissipation part 22.

[0031] The dustproof part 21 includes a vent 211 on the front side of the base 1. The inner side of the vent 211 has a mounting groove 212. The inner surface of the mounting groove 212 is fitted with a mounting plate 213. A dustproof net 214 is fixedly connected to the side of the mounting plate 213. The outer surface of the dustproof net 214 is fitted with the inner surface of the vent 211. The inner surface of the mounting groove 212 is rotatably connected to a shaft 215 via a bearing. The front end of the shaft 215 passes through the back of the mounting plate 213. The inner surface of the shaft 215 has a movable groove 216. The inner surface of the movable groove 216 is fixedly connected to a locking block 218 via an elastic sheet 217. The outer end of the locking block 218 is fitted with the inner surface of a slot 219 on the inner surface of the mounting plate 213. An adjusting spring 210 is fixedly connected to the side of the elastic sheet 217 away from the locking block 218.

[0032] In this embodiment, the number of elastic pieces 217 is set to four. The four elastic pieces 217 are arranged in pairs and are fixedly connected to the inner end face of the card block 218 respectively. The elastic pieces 217 are set in arc shape to form elastic support for the card block 218, ensuring that the card block 218 fits tightly with the card slot 219 and avoiding loosening or tilting caused by unilateral force.

[0033] Example 2: Based on Example 1, the high-voltage equipment shielding cover with integrated heat dissipation holes provided by this utility model, such as... Figures 1 to 6 As shown: The heat dissipation part 22 includes a drive motor 221 fixedly connected to the inner side of the back of the base 1. The output end of the drive motor 221 is fixedly connected to a main shaft 222. A fan blade 223 is fixedly connected to the outer wall of the front end of the main shaft 222. A transmission gear 224 is fixedly connected to the outer wall of the main shaft 222. A linkage gear 225 meshes with the side of the transmission gear 224. A secondary shaft 226 is fixedly connected to the inner wall of the linkage gear 225. A fan blade 223 is fixedly connected to the outer wall of the front end of the secondary shaft 226. The rear end of the secondary shaft 226 is rotatably connected to the inner side of the back of the base 1 through a bearing.

[0034] In this embodiment, the position of the fan blade 223 corresponds to the position of the vent 211.

[0035] Example 3: Based on Example 1, the high-voltage equipment shielding cover with integrated heat dissipation holes provided by this utility model, such as... Figures 1 to 6 As shown: The protective part 23 includes a protective plate 231 inserted into the inner surface of the base 1. A slider 232 is fixedly connected to the side of the protective plate 231. The outer end of the slider 232 penetrates the inner surface of the slot 233. An upper baffle 234 is fixedly connected to the top of the slider 232. A lower baffle 235 is fixedly connected to the bottom of the slider 232. A telescopic rod 236 is fixedly connected to the bottom of the slider 232. The bottom of the telescopic rod 236 is fixedly connected to the top of the connecting block 237. One side of the connecting block 237 is fixedly connected to the side of the base 1.

[0036] In this embodiment, the outer surface of the slider 232 is slidably connected to the inner surface of the slot 233 to ensure that the slider 232 drives the protective plate 231 to rise and fall smoothly.

[0037] Furthermore, the positions of the upper baffle 234 and the lower baffle 235 correspond to the positions of the slot 233 and slide in contact with the outside of the base 1. The upper baffle 234 and the lower baffle 235 can block the gap between the slot 233 and the slider 232, reducing the amount of rainwater and dust that seeps into the equipment through the slot 233.

[0038] In actual operation, when this device is used, the dustproof net 214 is aligned and snapped into the ventilation opening 211 on the front of the base 1, while the mounting plate 213 is snapped into the mounting groove 212. After the shaft 215 passes through the back of the mounting plate 213, the elastic piece 217 in the movable groove 216 pushes the locking block 218 into the locking groove 219 of the mounting plate 213, thus fixing the dustproof net 214. The dustproof net 214 prevents dust from entering the base 1 during heat dissipation. Conversely, by rotating the shaft 215, the locking block 218 is squeezed into the movable groove 216 and retracts, while the elastic piece 217 retracts, causing the locking block 218 to disengage from the locking groove 219. At this time, the mounting plate 213 can be pulled out to remove the dustproof net 214. After cleaning, it can be reinstalled, thus achieving quick disassembly of the dustproof net 214.

[0039] The slider 232 is controlled to slide up and down in the slot 233 by the telescopic rod 236, thereby controlling the protective plate 231 to slide up and down in the base 1, thus controlling the opening or closing of the heat dissipation hole 3. When it is open, heat dissipation can be carried out. At the same time, the opening and closing degree of the protective plate 231 can be adjusted according to the heat dissipation requirements. When the slider 232 moves up and down, the upper baffle 234 and the lower baffle 235 can cover the gap between the slot 233 and the slider 232, reducing the seepage of rainwater and dust into the equipment through the slot 233.

[0040] When the drive motor is powered on, it drives the main shaft to rotate. The main shaft meshes with the linkage gear through the transmission gear, which in turn drives the auxiliary shaft to rotate synchronously. At this time, the fan blades on the main shaft and the auxiliary shaft rotate simultaneously to generate directional airflow, which dissipates heat through the heat dissipation holes, thereby achieving rapid heat dissipation.
