Description

Technical Field

[0001] This utility model relates to the field of new energy high-voltage switchgear technology, specifically to a new energy high-voltage switchgear. Background Technology

[0002] High-voltage switchgear refers to high-voltage distribution cabinets. High-voltage distribution cabinets are electrical products used in power systems for power generation, transmission, distribution, power conversion and consumption, playing roles such as switching, control or protection. The voltage level ranges from 3.6kV to 550kV. They mainly include several categories such as high-voltage circuit breakers, high-voltage disconnect switches and grounding switches, high-voltage load switches, high-voltage automatic reclosers and sectionalizers, high-voltage operating mechanisms, high-voltage explosion-proof distribution devices and high-voltage switchgear.

[0003] The current high-voltage switchgear for new energy mainly consists of a cabinet, a mounting rack installed inside the cabinet, and a square door installed at the cabinet opening. While this type of high-voltage switchgear allows for convenient installation and use of electrical components, it also has drawbacks. Firstly, the cabinet door occupies space when opened, making it inconvenient to use in confined spaces. Secondly, the electrical components are secured to the mounting rack inside the switchgear using external bolts, which is cumbersome and makes subsequent disassembly and maintenance of the components inconvenient. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The technical problem to be solved by this utility model is to provide a new energy high-voltage switchgear that can reduce the excessive space occupied by the cabinet door when it is open, and can also achieve convenient clamping and fixing of various electrical components in a two-way clamping manner, so as to facilitate the efficient disassembly and maintenance of electrical components in the later stage.

[0006] (II) Technical Solution

[0007] This utility model is achieved through the following technical solution: This utility model proposes a new energy high-voltage switchgear, including a cabinet body. Two winding and shielding mechanisms are symmetrically installed on both sides of the opening of the cabinet body. Placement racks are installed sequentially from top to bottom inside the cabinet body. Each placement rack is equipped with a clamping mechanism. The winding and shielding mechanism includes a winding box installed on the cabinet body, a roll installed in the winding box, a shielding curtain wound around the outside of the roll, a magnetic suction column with a built-in lock installed at the free end of the shielding curtain, and a motor installed at the top center of the winding box. The clamping mechanism includes a bidirectional lead screw installed on the back of the placement rack, a worm gear installed at one end of the bidirectional lead screw, a worm gear arranged on the upper side of the worm gear, a handwheel installed at one end of the worm gear, clamping plates symmetrically installed at two sections of threaded parts with opposite directions on the bidirectional lead screw, and a sliding groove opened on the placement rack to cooperate with the clamping plates.

[0008] Furthermore, the roller is rotatably connected to the take-up box, and the shielding curtain passes through the take-up box and the side wall of the cabinet.

[0009] By adopting the above technical solution, after the roller rotates under the action of the motor, it will drive the curtain to roll up, so as to realize the convenient opening of the cabinet.

[0010] Furthermore, the upper and lower ends of the magnetic column are slidably connected to the cabinet body, and the magnetic column is connected to the curtain by screws.

[0011] By adopting the above technical solution, the magnetic columns are fixed to each other by means of their own locking mechanism when they are attracted to each other.

[0012] Furthermore, an operation panel is also installed on the outside of one of the winding boxes, and the operation panel is electrically connected to the motor.

[0013] By adopting the above technical solution, the operation panel can control the flexible start and stop of the motor according to actual usage needs.

[0014] Furthermore, both ends of the bidirectional lead screw are rotatably connected to the placement frame, and the bidirectional lead screw passes through the clamping plate and is threadedly connected to the clamping plate.

[0015] By adopting the above technical solution, the convenient rotation adjustment of the bidirectional lead screw can be ensured.

[0016] Furthermore, the clamping plate passes through the slide groove and is slidably connected to the slide groove, with the bottom end of the clamping plate located on the upper side of the bottom end of the placement frame.

[0017] By adopting the above technical solution, the bidirectional lead screw will cause the two clamping plates to move relative to each other under the action of thread transmission after rotation, so as to achieve clamping and fixing of electrical components.

[0018] Furthermore, the worm gear is bolted to the bidirectional lead screw, and the worm meshes with the worm gear.

[0019] By adopting the above technical solution, the worm gear rotates under the action of the worm, which will realize the synchronous rotation of the bidirectional lead screw.

[0020] Furthermore, the worm gear is rotatably connected to the placement frame, and the handwheel is welded to the worm gear.

[0021] By adopting the above technical solution, the rotation of the worm gear can be made more convenient with the help of the handwheel.

[0022] (III) Beneficial Effects

[0023] Compared with the prior art, this utility model has the following advantages:

[0024] To address the current issue that new energy high-voltage switchgear mainly consists of a cabinet, a mounting rack inside the cabinet, and a square door at the cabinet opening, while this structure allows for convenient installation and use of electrical components, it suffers from several drawbacks. Firstly, the door occupies space when opened, making it inconvenient to use in confined spaces. Secondly, securing the electrical components relies primarily on external bolts, which are cumbersome to remove, leading to difficulties in later disassembly and maintenance. This invention addresses this problem by symmetrically... The installation of two retractable curtain mechanisms to replace the original cabinet door allows the cabinet to be opened easily by retracting the curtain into the retractable box. This opening and closing method avoids excessive space occupation when the cabinet door is open, thus facilitating the convenient use of the new energy high-voltage switchgear in confined spaces. At the same time, by installing bidirectional clamping mechanisms on each placement rack inside the cabinet, after each electrical component is placed, the worm gear and worm wheel can be rotated by handwheel, thereby rotating the bidirectional lead screw. This allows the clamping plates to move closer together while the bidirectional lead screw is rotating, ensuring stable clamping of the electrical components. Since this fixing method allows the two clamping plates to be quickly removed with just one rotation, it facilitates efficient disassembly and maintenance of the electrical components later.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] like Figures 1-4 As shown, a new energy high-voltage switchgear in this embodiment includes a cabinet 1. Two winding and shielding mechanisms 2 are symmetrically installed on both sides of the opening of the cabinet 1. Placement racks 4 are installed sequentially from top to bottom inside the cabinet 1. Each placement rack 4 is equipped with a clamping mechanism 5. The winding and shielding mechanism 2 includes a winding box 202 installed on the cabinet 1, a drum 205 installed inside the winding box 202, a shielding curtain 203 wound around the outside of the drum 205, a magnetic suction post 204 with a built-in lock installed at the free end of the shielding curtain 203, and a motor 201 installed at the top center of the winding box 202. After the drum 205 rotates under the action of the motor 201, it drives the shielding curtain 203 to wind up, thereby realizing the winding and shielding mechanism 205. The body 1 is easy to open. The clamping mechanism 5 includes a bidirectional lead screw 505 installed on the back of the placement frame 4, a worm gear 502 installed at one end of the bidirectional lead screw 505, a worm 501 arranged on the upper side of the worm gear 502, a handwheel 503 installed at one end of the worm 501, a clamping plate 504 symmetrically installed on two sections of the bidirectional lead screw 505 with opposite screw threads, and a sliding groove 506 opened on the placement frame 4 to cooperate with the clamping plate 504. After the bidirectional lead screw 505 rotates, the two clamping plates 504 will move relative to each other under the action of the thread transmission to achieve clamping and fixing of electrical components. After the worm gear 502 rotates under the action of the worm 501, the bidirectional lead screw 505 will rotate synchronously.

[0033] like Figures 1-4As shown, in this embodiment, the roller 205 is rotatably connected to the winding box 202, the shielding curtain 203 passes through the winding box 202 and the side wall of the cabinet 1, the upper and lower ends of the magnetic column 204 are slidably connected to the cabinet 1, the magnetic column 204 and the shielding curtain 203 are connected by screws, and the magnetic columns 204 are fixed to each other by means of their own locks when they are attracted to each other.

[0034] like Figures 1-4 As shown in this embodiment, an operation panel 3 is also installed on the outside of one of the winding boxes 202. The operation panel 3 is electrically connected to the motor 201. The operation panel 3 can control the motor 201 to open and close flexibly according to actual usage needs.

[0035] like Figures 1-4 As shown, in this embodiment, the two ends of the bidirectional lead screw 505 are rotatably connected to the placement frame 4, the bidirectional lead screw 505 passes through the clamping plate 504 and is threadedly connected to the clamping plate 504, which can ensure convenient rotation and adjustment of the bidirectional lead screw 505. The clamping plate 504 passes through the slide groove 506 and is slidably connected to the slide groove 506. The bottom end of the clamping plate 504 is located on the upper side of the bottom end of the placement frame 4. The worm gear 502 is bolted to the bidirectional lead screw 505, the worm 501 meshes with the worm gear 502, the worm 501 is rotatably connected to the placement frame 4, and the handwheel 503 is welded to the worm 501. The handwheel 503 can make the rotation of the worm 501 more convenient.

[0036] The specific implementation process of this embodiment is as follows: In use, the electrical components are first placed on the rack 4 inside the cabinet 1. Then, the clamping mechanism 5 quickly clamps and fixes the electrical components. Next, the opening of the cabinet 1 is closed by the retracting and blocking mechanism 2, allowing the new energy high-voltage switchgear to be put into use. During use, by symmetrically installing two retracting and blocking mechanisms 2 at the opening of the cabinet 1 to replace the original cabinet door, the cabinet 1 can be opened by retracting the blocking curtain 203 into the retracting box 202, thus achieving convenient opening of the cabinet 1. Because of this opening and closing method, the cabinet... The excessive space occupied when the door is open facilitates the convenient use of the new energy high-voltage switchgear in confined spaces. At the same time, by installing a two-way clamping mechanism 5 on each placement rack 4 inside the cabinet 1, after each electrical component is placed, the worm gear 501 and worm wheel 502 can be rotated by the handwheel 503, thereby rotating the two-way lead screw 505. This allows the clamping plates 504 to move closer to each other while the two-way lead screw 505 is rotating, ensuring stable clamping of the electrical components. Since the two clamping plates 504 can be quickly moved apart with just one rotation under this fixing method, it is convenient for efficient disassembly and maintenance of the electrical components in the future.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
