Description

Technical Field

[0001] This utility model relates to the field of power distribution switchgear, and more particularly to an outdoor high-voltage switchgear. Background Technology

[0002] High-voltage switchgear refers to electrical products used in power systems for power generation, transmission, distribution, energy conversion and consumption, which play the roles of switching, control or protection. It mainly includes several categories such as high-voltage circuit breakers, disconnecting switches and load switches, and occupies a very important position in the entire power industry.

[0003] In related technologies, there exists an outdoor high-voltage switchgear, including a cabinet body. Two blowers are fixedly installed on the bottom of the inner wall of the cabinet body, a ventilation mesh is fixedly installed on the inner wall of the cabinet body, a controller is fixedly installed on the front of the cabinet door, a placement mechanism is provided inside the cabinet body, and a handle is fixedly installed on the front of the cabinet door. This high- and low-voltage power switchgear for power engineering utilizes the placement mechanism inside the cabinet body. During assembly, the required electrical components are secured to the threaded holes on the top of the fixing block with screws. Then, according to the required installation position of the electrical components, the fixing block is passed through the corresponding assembly hole. At this time, the locking block retracts into the slot as it passes through the assembly hole, and returns to its original position after passing through the assembly hole, thereby fixing the electrical components on the fixing block to the assembly plate. This solves the problem of the inability to freely adjust the position of electrical components in existing high- and low-voltage power switchgear on the market.

[0004] Regarding the aforementioned technologies, the inventor believes that existing cabinets typically have several ventilation nets installed to address the issue of ventilation and prevent fires caused by excessive internal temperatures. However, if rainwater is dense and sloping, it can easily enter the cabinet directly or flow into it along the cabinet walls, causing water accumulation and damage to internal wiring. Therefore, there is room for improvement. Utility Model Content

[0005] To reduce the problem of rainwater being concentrated and sloping, easily entering the cabinet directly or flowing into the cabinet along the cabinet wall, causing water accumulation inside the cabinet and damaging the internal wiring, this utility model provides an outdoor high-voltage switchgear.

[0006] The outdoor high-voltage switchgear provided by this utility model adopts the following technical solution:

[0007] An outdoor high-voltage switchgear includes a cabinet, a mounting frame, and a shielding curtain placed within the mounting frame. The cabinet has a ventilation mesh on its circumferential side wall. The mounting frame is located on the side of the cabinet away from the ground and is arranged circumferentially around the cabinet. The mounting frame has a mounting cavity that extends through the side of the mounting frame closest to the cabinet. The shielding curtain is located within the mounting cavity. The switchgear also includes a drive assembly that moves the shielding curtain out of the mounting cavity to shield the ventilation mesh.

[0008] By adopting the above technical solution, and by installing a shielding curtain above the cabinet, when it rains, the drive component will move the shielding curtain out of the installation cavity to cover the ventilation net, preventing rainwater from directly entering the cabinet through the ventilation net, reducing the problem of water accumulation inside the cabinet, preventing damage to internal circuits, and improving the safety of the cabinet.

[0009] Optionally, the drive assembly includes a baffle, and the cabinet is provided with a sliding rail. The sliding rail includes a connecting part and a supporting part. There are two connecting parts, and one end of each connecting part is fixedly connected to the cabinet. The two ends of the supporting part are respectively fixedly connected to the ends of the two connecting parts away from the cabinet. The connecting part and the supporting part cooperate to form a space for the curtain to pass through. The baffle is slidably connected to the connecting part to open or seal the installation cavity.

[0010] By adopting the above technical solution, the baffle is supported by the connecting part and the supporting part of the slide rail. When it is not raining, the baffle is kept in the mounting frame, and the shielding curtain is stored in the mounting frame. This allows the cabinet door to be opened normally, and also allows the ventilation net to play a ventilation role when it is not raining, ensuring the normal operation of the high-voltage cabinet.

[0011] Optionally, a gap is provided between the mounting bracket and the support for the baffle to slide out. The drive assembly also includes a connecting rope, which is a plurality of ropes arranged along the length of the baffle. One end of the connecting rope is connected to the side of the baffle away from the cabinet, and the other end of the connecting rope extends out of the gap away from the mounting cavity.

[0012] By adopting the above technical solution, on the one hand, by setting gaps, the sliding distance of the baffle is increased, exposing more space for the corresponding curtain to fall, thus improving the efficiency of the curtain's blocking; on the other hand, by connecting the baffle with a connecting rope, the user does not need to hold the baffle, but only needs to pull the connecting rope to move the baffle, which is convenient for the user to operate and improves the moving efficiency of the baffle.

[0013] Optionally, a limiting plate is provided on one side of the baffle. When the baffle moves away from the cabinet, the limiting plate abuts against the side of the support near the cabinet.

[0014] By adopting the above technical solution, and by providing a limiting plate on one side of the baffle, when it rains, when the driving component drives the baffle to slide along the sliding track to a certain distance away from the cabinet, the limiting plate abuts against the support part, limiting the distance the baffle moves, preventing the baffle from moving too far and falling off, and improving the stability of the baffle installed on the sliding track.

[0015] Optionally, the cabinet is provided with a water storage tank, the water storage tank is provided with a water storage trough, the drive assembly also includes a float, the float is disposed in the water storage trough, the bottom wall of the water storage trough is provided with a through hole for the connecting rope to pass through from bottom to top, the hole wall of the through hole is provided with a sealing ring to seal the part except for the through hole through which the connecting rope passes, and the end of the connecting rope away from the baffle is connected to the float.

[0016] By adopting the above technical solution, and by setting up a water storage tank, rainwater is collected in the water storage tank when it rains, providing sufficient buoyancy to drive the connecting rope to pull the baffle, so that the baffle moves out and the curtain moves out of the installation cavity, thus realizing the automation of the curtain moving out to provide rain protection on rainy days.

[0017] Optionally, a guide block is fixedly connected to the outer peripheral side wall of the mounting bracket. The guide block has a guide hole. The end of the connecting rope that extends into the gap away from the mounting cavity passes around the guide block and is connected to the float.

[0018] By adopting the above technical solution, a guide block is installed on the outer peripheral side wall of the mounting frame, allowing the connecting rope to pass through the guide hole and connect with the float and the baffle. This guides the connecting rope to move along the sliding direction of the baffle, ensuring that the force on the baffle is consistent with the direction of movement. This reduces the drawbacks caused by force decomposition, avoids insufficient force on the baffle due to excessive deviation of the connecting rope movement after the float rises, and improves the driving efficiency of the drive assembly.

[0019] Optionally, the guide hole is rounded on the side near the mounting bracket.

[0020] By adopting the above technical solution, and by setting the guide hole to a rounded corner on the side near the mounting bracket, the movement of the connecting rope is guided more smoothly, reducing the friction between the connecting rope and the guide hole when the connecting rope moves under force, reducing the wear of the connecting rope, and extending the service life of the connecting rope.

[0021] Optionally, the water storage tank is equipped with a rain-guiding plate, the height of which gradually decreases from the middle to both sides.

[0022] By adopting the above technical solution, and by installing rain-guiding plates on the water storage tank with a gradually decreasing height from the middle to both sides, rainwater is radially diverted along the inclined surface when it rains, so that the rainwater can be diverted to the water storage tanks in different directions in the first time, which significantly improves the rainwater collection efficiency per unit time.

[0023] Optionally, the mounting frame is provided with a curtain tube, which rotates around its own axis, and the shielding curtain is disposed on the curtain tube.

[0024] By adopting the above technical solution, a curtain tube is installed inside the mounting frame, and the curtain is wound around the curtain tube. When it is not raining, the curtain is neatly and regularly stored in the mounting frame, which is less likely to cause large friction between them and block the installation cavity due to storage problems. This allows the curtain to be moved out smoothly and improves the blocking efficiency of the curtain.

[0025] Optionally, a handle is fixedly connected to one end of the curtain tube.

[0026] By adopting the above technical solution, and by providing a handle at one end of the curtain tube, when the blind curtain is fully unfolded and needs to be retracted, the curtain tube can be rotated synchronously by rotating the handle, and the blind curtain will be rotated back onto the curtain tube, making the blind curtain retraction process more efficient and labor-saving, and improving the overall user experience.

[0027] In summary, this utility model has at least one of the following beneficial technical effects:

[0028] By installing a shielding curtain above the cabinet, rainwater is prevented from directly entering the cabinet through the ventilation net, thus preventing damage to the internal wiring and improving the cabinet's safety.

[0029] By incorporating a water storage tank and a water storage trough, the buoyancy of the collected rainwater on the float in the water storage trough is converted into tension and transmitted to the baffle through a connecting rope. After the baffle is moved out, the curtain is moved out of the installation cavity, thus automating the removal of the curtain for rain protection on rainy days. Attached Figure Description

Detailed Implementation

[0037] The following is in conjunction with the appendix Figure 1-6 The present invention will be further described in detail with reference to the embodiments.

[0038] This utility model discloses an outdoor high-voltage switchgear. (Refer to...) Figure 1 An outdoor high-voltage switchgear includes a cabinet body 1 and a rain shelter system 2. The rain shelter system 2 is installed on the cabinet body 1 and provides circumferential protection to the side walls of the cabinet body 1 when it rains.

[0039] Reference Figure 1 and Figure 2 The rain shelter system 2 includes a mounting frame 21, a curtain tube 22, a rain shelter curtain 23, and a drive assembly 24. The mounting frame 21 is fixedly connected to the top of the cabinet 1 to provide an installation position for the rain shelter system 2. The mounting frame 21 is arranged circumferentially around the cabinet 1. The mounting frame 21 has an installation cavity 211 extending through its lower side. The curtain tube 22 is rotatably connected to the installation cavity 211 of the mounting frame 21 on each side. The cabinet 1 has a ventilation mesh 11 around its perimeter. The rain shelter curtain 23 is wrapped around the curtain tube 22. When the rain shelter curtain 23 moves downwards, it covers the ventilation mesh 11 of the cabinet 1 below. A load-bearing bar 231 is fixedly connected to one side of the rain shelter curtain 23, extending along the length of the curtain 23 to pull the curtain 23 downwards. To facilitate the retraction of the rain shelter curtain 23, a handle 221 is also fixedly connected to one end of the curtain tube 22 for user grip.

[0040] To prevent the blind curtain 23 from moving downwards in sunny weather, a baffle 212 is also installed on the mounting frame 21. A sliding track 12 is installed on the cabinet 1, and the sliding track 12 is arranged along the direction of the mounting frame 21. The sliding track 12 includes a support part 121 and a connecting part 122. There are two connecting parts 122. The two ends of the support part 121 are respectively fixedly connected to one end of the two connecting parts 122, and the other end of the connecting parts 122 is fixedly connected to the cabinet 1 to form the sliding track 12. The baffle 212 is slidably connected to the connecting part 122 so that the baffle 212 covers or opens the mounting cavity 211.

[0041] In order to allow the baffle 212 to move sufficiently, a gap 213 is left between the support 121 and the mounting bracket 21, which allows the baffle 212 to pass through, thereby increasing the exposed area of ​​the mounting cavity 211.

[0042] Reference Figure 1 and Figure 3 A limiting plate 2121 is installed on the lower side of the baffle 212 near the cabinet 1. After the baffle 212 moves a certain distance, the limiting plate 2121 will abut against the support part 121, limiting the distance the baffle 212 moves, preventing the baffle 212 from moving too far and falling off, and improving the stability of the baffle 212 on the sliding track 12.

[0043] Reference Figure 1 and Figure 4 To enable the baffle 212 to move automatically in rainy weather, the drive assembly 24 also includes a connecting rope 241 and a float 242. One end of the connecting rope 241 is connected to the baffle 212, so that the baffle 212 can be moved by pulling the connecting rope 241. A water storage tank 13 is installed above the cabinet 1, and the water storage tank 13 is arranged around the circumference of the cabinet 1. A water storage trough 131 is provided in the water storage tank 13. The float 242 is located in the water storage trough 131. The bottom wall of the water storage trough 131 has a through hole 1311. The connecting rope 241 passes through the through hole 1311 and is fixedly connected to the float 242. When it rains, rainwater accumulates in the water storage trough 131, providing sufficient buoyancy for the float 242 to drive the connecting rope 241 to pull the baffle 212. In order to prevent water in the water storage tank 131 from easily passing through the through hole 1311, a sealing ring 13111 is also installed on the hole wall of the through hole 1311. When the connecting rope 241 passes through the through hole 1311, the sealing ring 13111 works with the connecting rope 241 to seal the through hole 1311.

[0044] Reference Figure 1 and Figure 5 To ensure that the pulling direction of the connecting rope 241 on the baffle 212 is consistent with the moving direction of the baffle 212, and to reduce the magnitude of force decomposition in the vertical moving direction, a guide block 214 is installed on the side of the mounting bracket 21 away from the cabinet 1. The guide block 214 has a guide hole 2141 on the side away from the mounting bracket 21, through which the connecting rope 241 passes. The guide hole 2141 is rounded on the side closest to the cabinet 1, which can more smoothly guide the movement of the connecting rope 241, reduce friction between the connecting rope 241 and the guide block 214, and extend the service life of the connecting rope 241.

[0045] Reference Figure 1 , Figure 4 and Figure 6A rain-guiding plate 1312 is installed in the water storage tank 13. The height of the rain-guiding plate 1312 gradually decreases from the middle to both sides. When it rains, the rain-guiding plate 1312 can guide rainwater into the water storage tank 131, which accelerates the accumulation of rainwater, reduces the time for the float 242 to feel the buoyancy of the rainwater, improves the sensitivity of the drive device, and speeds up the automatic falling speed of the curtain 23.

[0046] The implementation principle of an outdoor high-voltage switchgear according to this utility model embodiment is as follows: When it rains, rainwater flows into the water storage tank 131 along the rain-guiding plate 1312. When the water level in the water storage tank 131 rises, the float 242 rises accordingly, pulling the connecting rope 241 connected to the float 242. The other end of the connecting rope 241 passes around the guide block 214 and pulls the baffle 212 to move away from the cabinet 1, thereby exposing the installation cavity 211. This causes one end of the shielding curtain 23 to lose support and fall, thereby shielding the cabinet 1. When the rain stops, the user holds the handle 221 and rotates it to retract the shielding curtain 23 into the installation cavity 211. Then, the baffle 212 is pushed to slide along the sliding track 12, thereby closing the installation cavity 211 and preventing the shielding curtain 23 from falling freely.

[0047] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
