Description

Technical Field

[0001] This utility model relates to the field of electrical engineering technology, specifically to a switch cabinet for electrical engineering. Background Technology

[0002] Switchgear is a crucial piece of equipment in electrical engineering. Also known as a complete switch or complete power distribution unit, switchgear is an electrical device with a circuit breaker as its core. It assembles high and low voltage electrical appliances (including control appliances, protection appliances, and measuring appliances), as well as components such as busbars, current-carrying conductors, and insulators, into a closed or open metal cabinet according to the requirements of the primary electrical wiring diagram. Thus, it constitutes a key device for receiving and distributing electrical energy in the power system.

[0003] Switchgear mainly consists of two parts: the cabinet and the electrical components. The cabinet is the outer shell of the switchgear, used to protect the internal electrical components from the influence of the external environment. The electrical components include primary electrical components and secondary electrical components. Together, they constitute the complete system of the switchgear. Switchgear can be classified according to different classification standards, such as high-voltage switchgear and low-voltage switchgear according to voltage level; and fixed switchgear and withdrawable (handcart type) switchgear according to structural form. Different types of switchgear have different characteristics and application scenarios.

[0004] When switchgear is installed outdoors, and maintenance is required during rainy or snowy weather, the internal components are easily damaged by rain and snow, making maintenance work difficult. At the same time, when the bottom of the switchgear is close to the ground, ground moisture can enter the switchgear through the ventilation holes, causing electrical components to become damp and affecting their use. Therefore, a switchgear for electrical engineering is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a switch cabinet for electrical engineering, which has the advantages of facilitating maintenance even in rainy or snowy weather. It solves the problem that when the switch cabinet is installed outdoors and maintenance is required in rainy or snowy weather, the internal components of the switch cabinet are easily damaged by rain and snow, making maintenance work inconvenient. At the same time, when the bottom of the switch cabinet is close to the ground, ground moisture can enter the switch cabinet through the ventilation holes, causing electrical components to become damp and affecting their use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a switch cabinet for electrical engineering, comprising a switch cabinet body, wherein a shielding structure is provided on the top of the switch cabinet body, and a moisture-proof structure is provided inside the switch cabinet body;

[0007] The shielding structure includes a support rod, a support rod is fixedly installed on the top of the switch cabinet body, a shielding box is fixedly installed on the top of the support rod, an extension plate is slidably installed inside the shielding box, a fixing post is fixedly installed on the top of the switch cabinet body, a motor is fixedly installed on the right side of the fixing post, a turntable is rotatably installed on the left side of the fixing post, an adjusting rod is fixedly installed on the left side of the turntable, a limit rod is fixedly installed on the left side of the fixing post, a swing shaft is rotatably installed outside the limit rod, a limit groove is fixedly installed on the top of the fixing post, a moving plate is slidably installed inside the limit groove, and a connecting rod is fixedly installed on the left side of the moving plate.

[0008] The moisture-proof structure includes a ventilation plate. The ventilation plate is fixedly installed on the inner top wall of the switch cabinet body. A connecting frame is fixedly installed inside the switch cabinet body. A fan is fixedly installed on the top of the connecting frame. A sealing plate is hinged to the inner bottom of the switch cabinet body. A fixing plate is fixedly installed on the bottom of the switch cabinet body. An electric telescopic rod is hinged to the outside of the fixing plate.

[0009] Furthermore, the extension plate is sleeved with the shielding box, and the top of the movable plate passes through the shielding box and is fixedly connected to the extension plate.

[0010] Furthermore, the output shaft of the motor passes through the fixed pile and is fixedly connected to the turntable, and two sliding grooves are opened inside the swing shaft.

[0011] Furthermore, the adjusting rod passes through one of the slide grooves and is slidably connected to the slide groove, and the connecting rod passes through the other slide groove and is slidably connected to the slide groove.

[0012] Furthermore, the top of the fan is close to the ventilation plate, and the bottom of the shielding box is close to the ventilation plate.

[0013] Furthermore, there are two sealing plates, which are positioned opposite each other and located at the bottom inner part of the switch cabinet body.

[0014] Furthermore, the fixing plate is close to the sealing plate, and the top of the electric telescopic rod is hinged to the sealing plate.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] This electrical engineering switchgear uses a motor that, when activated, moves via a turntable, adjusting rod, swing shaft, connecting rod, and moving plate. This causes the extension plate to extend beyond the shielding box, thus shielding the top front of the switchgear during maintenance. When rain or snow accumulates on the ground, the electric telescopic rod is activated to close the sealing plate, preventing ground moisture from entering the switchgear through the opening at the bottom and causing moisture damage to the electrical components.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 In this embodiment, a switch cabinet for electrical engineering includes a switch cabinet body 1, a shielding structure 2 on the top of the switch cabinet body 1, and a moisture-proof structure 3 inside the switch cabinet body 1.

[0025] The shielding structure 2 includes a support rod 201. The support rod 201 is fixedly installed on the top of the switch cabinet body 1. A shielding box 202 is fixedly installed on the top of the support rod 201. An extension plate 203 is slidably installed inside the shielding box 202. A fixing post 204 is fixedly installed on the top of the switch cabinet body 1. A motor 205 is fixedly installed on the right side of the fixing post 204. A turntable 206 is rotatably installed on the left side of the fixing post 204. An adjusting rod 207 is fixedly installed on the left side of the turntable 206. A limiting rod 208 is fixedly installed on the left side of the fixing post 204. A swing shaft 209 is rotatably installed on the outside of the limiting rod 208. A limiting groove 210 is fixedly installed on the top of the fixing post 204. A moving plate 211 is slidably installed inside the limiting groove 210. A connecting rod 212 is fixedly installed on the left side of the moving plate 211.

[0026] The moisture-proof structure 3 includes a ventilation plate 301. The ventilation plate 301 is fixedly installed on the inner top wall of the switch cabinet body 1. A connecting frame 302 is fixedly installed inside the switch cabinet body 1. A fan 303 is fixedly installed on the top of the connecting frame 302. A sealing plate 304 is hinged to the inner bottom of the switch cabinet body 1. A fixing plate 305 is fixedly installed on the bottom of the switch cabinet body 1. An electric telescopic rod 306 is hinged to the outside of the fixing plate 305.

[0027] exist Figure 5 In the middle, the extension plate 203 is sleeved with the shielding box 202, and the top of the movable plate 211 passes through the shielding box 202 and is fixedly connected to the extension plate 203. By increasing the area of ​​the shielding box 202 covering the top of the switch cabinet body 1, when the switch cabinet body 1 is under maintenance, the extension plate 203 can effectively prevent rain and snow from entering the interior of the switch cabinet body 1.

[0028] exist Figure 4 In the middle, the adjusting rod 207 passes through one of the slide grooves and is slidably connected to the slide groove, and the connecting rod 212 passes through the other slide groove and is slidably connected to the slide groove. When the swing shaft 209 swings according to the adjusting rod 207, it will swing around the limiting rod 208 as the center point. Thus, while the top of the swing shaft 209 swings, it will drive the moving plate 211 to move according to the connecting rod 212.

[0029] exist Figure 3 In the middle, the output shaft of the motor 205 passes through the fixed pile 204 and is fixedly connected to the turntable 206. The swing shaft 209 has two sliding grooves inside. The limiting groove 210 limits the moving plate 211 while supporting the moving plate 211 according to the fixed pile 204, so that the moving plate 211 remains stable when it moves.

[0030] When implementing this procedure, follow these steps: When using the switch cabinet body 1, if maintenance is required in rainy or snowy weather, turn on the motor 205. This will cause the extension plate 203 to extend out of the shielding box 202, thus shielding the top front of the switch cabinet body 1 during maintenance. This prevents rain and snow from contacting the electrical components inside the switch cabinet body 1 when it is open, which could damage the electrical components. In rainy or snowy weather, if there is accumulated rain and snow on the ground, manually operate the electric telescopic rod 306 to adjust the sealing plate 304 to a closed state. This prevents moisture from the ground from entering the switch cabinet body 1 through the opening at the bottom of the switch cabinet body 1, which could cause the electrical components of the switch cabinet body 1 to become damp.

[0031] In summary, when the switch cabinet body 1 needs maintenance in rainy or snowy weather, the motor 205 is turned on, driving the turntable 206 to rotate. This causes the adjusting rod 207 to slide inside the swing shaft 209, resulting in the swing shaft 209 swinging. The connecting rod 212 follows the swing of the swing shaft 209, driving the moving plate 211 to move. This causes the extension plate 203 to extend outside the shielding box 202, thus shielding the top front of the switch cabinet body 1 during maintenance. This prevents rain and snow from contacting the electrical components inside the switch cabinet body 1 when it is open, thus preventing damage to the electrical components. In snowy weather, when snow and rain accumulate on the ground, the electric telescopic rod 306 is manually operated to adjust the sealing plate 304 to a closed state. This prevents ground moisture from entering the switch cabinet body 1 through the opening at the bottom of the switch cabinet body 1, thus preventing the electrical components of the switch cabinet body 1 from becoming damp. This solves the problem that when the switch cabinet is installed outdoors and needs to be maintained in rainy or snowy weather, the internal components of the switch cabinet are easily affected by rain and snow, which can damage the components and hinder maintenance work. At the same time, when the bottom of the switch cabinet is close to the ground, ground moisture can enter the switch cabinet through the vent holes, causing the electrical components to become damp and affecting their use.
