Description

Technical Field

[0001] This utility model relates to the field of electrical control cabinet technology, specifically an outdoor electrical control cabinet. Background Technology

[0002] An electrical control cabinet is a type of cabinet used for centralized control and protection of electrical equipment. It can install various electrical components in a closed space and achieve multiple functions such as control, protection, and monitoring of electrical equipment through reasonable wiring and circuit connections. The electrical control cabinet is like the "brain" and "bodyguard" of the electrical system, playing a vital role in the normal operation of the entire electrical system.

[0003] Due to the complex and ever-changing outdoor environment, outdoor electrical control cabinets must have good protective performance. Outdoor temperatures and humidity vary greatly, and they may also face severe weather such as rainstorms, strong winds, and sandstorms, as well as direct sunlight. It is essential to ensure that the equipment can operate normally under harsh outdoor conditions.

[0004] The prior art patent document CN221807560U provides an outdoor electrical control cabinet. This cabinet uses a push-pull frame controlled by a drive mechanism to flexibly block or open the ventilation holes, ensuring good ventilation and heat dissipation inside the cabinet while effectively preventing rainwater and debris from entering and protecting the safe operation of electrical components. At the same time, the addition of a rainproof canopy and rubber sealing gaskets further improves the waterproof and dustproof performance of the cabinet, enhances its stability and reliability in harsh environments, and ensures that the ventilation and heat dissipation requirements inside the cabinet are met.

[0005] The aforementioned existing technology, although the electrical control cabinet can flexibly block or open the ventilation holes through the push-pull frame controlled by the drive mechanism, ensuring good ventilation and heat dissipation inside the electrical control cabinet, has the problem that the dust filter in the electrical control cabinet will become clogged during long-term use and needs to be replaced. The dust filter is generally installed by bolt fixing, and the replacement process requires tools, which is very cumbersome and cannot be quickly and conveniently disassembled and assembled, reducing its practicality. Therefore, we need an outdoor electrical control cabinet. Utility Model Content

[0006] The purpose of this utility model is to provide an outdoor electrical control cabinet to solve the problem that the dustproof net in the electrical control cabinet of the patented technology mentioned in the background art will become clogged during long-term use and needs to be replaced. The dustproof net is generally installed by bolt fixing, and the replacement process requires tools, which is very cumbersome and cannot be quickly and conveniently disassembled and assembled, thus reducing its practicality.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An outdoor electrical control cabinet includes a base, a cabinet body is provided on the top of the base, a dustproof net is installed on one side of the cabinet body, a disassembly assembly is provided on one side of the cabinet body, and a buffer assembly is provided inside the base.

[0009] The assembly and disassembly assembly includes a fixing block, a rotating rod installed inside the fixing block, and a first bevel gear fixedly connected to one end of the rotating rod. A second bevel gear meshes with the outer wall of the first bevel gear, and a lead screw is fixedly connected to the inner wall of the second bevel gear. A positioning rod is threaded onto the outer surface of the lead screw, and a positioning groove is provided on one side of the dustproof net.

[0010] The buffer assembly includes a movable plate, a sliding plate rotatably connected to the bottom of the movable plate, a first spring installed on one side of the sliding plate, a fixed rod slidably connected to the inner wall of the sliding plate, a second spring fixedly connected inside the base, and a damper installed on the inner wall of the second spring.

[0011] Preferably, the cabinet body has a cabinet door installed on the front, and a rain shield is fixedly connected to the top of the cabinet body.

[0012] Preferably, the fixed block forms a rotating structure with the first bevel gear through a rotating rod, and the shape and size of the outer wall of the first bevel gear match the shape and size of the outer wall of the second bevel gear. The rotating rod forms a rotating structure with the first bevel gear and the second bevel gear.

[0013] Preferably, the second bevel gear forms a lifting structure with the lead screw and the positioning rod, and the external thread of the lead screw matches the internal thread of the positioning rod.

[0014] Preferably, the dustproof net forms an engaging structure with the positioning rod through the positioning groove, and the shape and size of the positioning rod match the shape and size of the positioning groove. The positioning grooves are symmetrically arranged about the vertical axis of the dustproof net.

[0015] Preferably, the movable plate forms a sliding structure with the moving plate and the fixed rod, and the movable plate is disposed between the cabinet and the moving plate, and the fixed rod forms an elastic structure with the moving plate through the first spring.

[0016] Preferably, the base forms an elastic structure with the cabinet through a second spring, and there are multiple second springs.

[0017] Compared with the prior art, the beneficial effects of this utility model are: this outdoor electrical control cabinet,

[0018] First, this utility model includes a fixing block, a rotating rod, a first bevel gear, a second bevel gear, a lead screw, a positioning rod, and a positioning groove. By manually rotating the rotating rod, the first bevel gear can be driven to rotate, simultaneously driving the second bevel gear to rotate. During the rotation of the second bevel gear, the lead screw will rotate within the positioning rod, causing the positioning rod to rise and fall. When both positioning rods move inward simultaneously, they extend into the positioning groove to limit and fix the dustproof net. When the positioning rods move outward, they can detach from the positioning groove, releasing the limitation and fixation of the dustproof net. This achieves the effect of facilitating the assembly and disassembly of the dustproof net, improving its practicality.

[0019] Secondly, this utility model is equipped with a movable plate, a sliding plate, a first spring, a fixed rod, a second spring, and a damper. When the electrical control cabinet vibrates, the vibration is transmitted to the movable plate through the cabinet body, causing the movable plate to rotate and drive the sliding plate to move. During the movement of the sliding plate, it is restricted by the first spring, which then buffers the vibration. At the same time, the vibration can be further buffered by the action of the second spring and the damper to prevent the vibration from affecting the equipment inside the electrical control cabinet.

[0025] 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.

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 An outdoor electrical control cabinet includes a base 1, a cabinet 2 on the top of the base 1, a dustproof net 3 on one side of the cabinet 2, a disassembly assembly 4 on one side of the cabinet 2, and a buffer assembly 7 inside the base 1.

[0027] The assembly and disassembly assembly 4 includes a fixing block 401. A rotating rod 402 is installed inside the fixing block 401. A first bevel gear 403 is fixedly connected to one end of the rotating rod 402. A second bevel gear 404 meshes with the outer wall of the first bevel gear 403. A lead screw 405 is fixedly connected to the inner wall of the second bevel gear 404. A positioning rod 406 is threaded onto the outer surface of the lead screw 405. A positioning groove 407 is provided on one side of the dustproof net 3.

[0028] The buffer assembly 7 includes a movable plate 701, a movable plate 702 rotatably connected to the bottom of the movable plate 701, a first spring 703 installed on one side of the movable plate 702, a fixed rod 704 slidably connected to the inner wall of the movable plate 702, a second spring 705 fixedly connected inside the base 1, and a damper 706 installed on the inner wall of the second spring 705.

[0029] Through the above technical solution, by manually rotating the rotating rod 402, the first bevel gear 403 can be rotated, and the second bevel gear 404 can be rotated simultaneously. During the rotation of the second bevel gear 404, the lead screw 405 will rotate within the positioning rod 406, causing the positioning rod 406 to rise and fall. When both positioning rods 406 move inward simultaneously, they will extend into the positioning groove 407 to limit and fix the dustproof net 3. When the positioning rods 406 move outward, they can disengage from the positioning groove 407, releasing the limitation and fixation of the dustproof net 3. This achieves the effect of facilitating the disassembly and assembly of the dustproof net 3 and improving its practicality.

[0030] Specifically, cabinet door 5 is installed on the front of cabinet 2, and rain shield 6 is fixedly connected to the top of cabinet 2.

[0031] The above technical solution facilitates the opening of cabinet door 5 to inspect and maintain the equipment inside the electrical control cabinet, and the rain shield 6 allows rainwater to flow down from both sides on rainy days.

[0032] Specifically, the fixed block 401 forms a rotating structure with the first bevel gear 403 through the rotating rod 402, and the shape and size of the outer wall of the first bevel gear 403 match the shape and size of the outer wall of the second bevel gear 404. The rotating rod 402 forms a rotating structure with the first bevel gear 403 and the second bevel gear 404.

[0033] The above technical solution facilitates the rotation of the first bevel gear 403 by manually rotating the lever 402. Since the first bevel gear 403 and the second bevel gear 404 mesh with each other, the first bevel gear 403 drives the second bevel gear 404 to rotate synchronously, thus achieving the effect of the second bevel gear 404 rotating.

[0034] Specifically, the second bevel gear 404 forms a lifting structure with the lead screw 405 and the positioning rod 406, and the external thread of the lead screw 405 matches the internal thread of the positioning rod 406.

[0035] The above technical solution facilitates the rotation of the second bevel gear 404 while driving the lead screw 405 to move up and down within the positioning rod 406. The positioning rod 406 is square in shape, which ensures that the positioning rod 406 can only maintain the up and down movement, thus achieving the effect of the positioning rod 406 moving up and down.

[0036] Specifically, the dustproof net 3 forms an engaging structure with the positioning rod 406 through the positioning groove 407, and the shape and size of the positioning rod 406 match the shape and size of the positioning groove 407. The positioning grooves 407 are symmetrically arranged about the vertical axis of the dustproof net 3.

[0037] The above technical solution facilitates the positioning rod 406 to extend into the positioning groove 407 to limit and fix the dustproof net 3 vertically, so that the dustproof net 3 is fixedly installed at the ventilation opening on one side of the cabinet 2. When the positioning rod 406 is disengaged from the positioning groove 407, the dustproof net 3 is released from the limit and fixed position. Pulling the dustproof net 3 can disassemble the dustproof net 3, thus achieving the effect of facilitating the disassembly and installation of the dustproof net 3.

[0038] Specifically, the movable plate 701 forms a sliding structure with the movable plate 702 and the fixed rod 704, and the movable plate 701 is located between the cabinet 2 and the movable plate 702. The fixed rod 704 forms an elastic structure with the movable plate 702 through the first spring 703.

[0039] The above technical solution facilitates the rotation of the movable plate 701 when the cabinet 2 vibrates. The rotation of the movable plate 701 will drive the moving plate 702 to move on the fixed rod 704. During the movement of the moving plate 702, the first spring 703 will be compressed or extended, so that the first spring 703 can initially buffer the vibration.

[0040] Specifically, the base 1 forms an elastic structure with the cabinet 2 through the second spring 705, and there are multiple second springs 705.

[0041] The above technical solution facilitates further buffering of the vibration of the cabinet 2 under the action of the second spring 705 and the damper 706, reduces the rebound force of multiple springs, and thus reduces the vibration effect.

[0042] Working principle: When using this outdoor electrical control cabinet, firstly, when replacing the dustproof net 3, manually rotate the rotating rod 402. The rotating rod 402 drives the first bevel gear 403 to rotate, which in turn drives the second bevel gear 404 to rotate. The second bevel gear 404 drives the lead screw 405 to rotate, which in turn drives the positioning rod 406 to move outward, thus disengaging the positioning rod 406 from the positioning groove 407, releasing the limiting fixation of the dustproof net 3. The dustproof net 3 can then be pulled out. Next, the new dustproof net 3 is reinserted into the ventilation opening. Reverse the rotating rod 402. The rotation of the rotating rod 402, through the first bevel gear 403, the second bevel gear 404, and the lead screw 405, drives the positioning rod 406 outward. The positioning rod 406 moves inward, allowing it to extend into the positioning groove 407 to limit and fix the dustproof net 3, thus completing the replacement of the dustproof net 3. When the electrical control cabinet vibrates, the cabinet body 2 will drive the movable plate 701 to rotate. The rotation of the movable plate 701 will drive the moving plate 702 to move. The moving plate 702 will slide on the fixed rod 704. Under the action of the first spring 703, the vibration will be buffered. Under the action of the second spring 705 and the damper 706, the rebound force of multiple springs can be reduced, further buffering the vibration. This completes all the work. The contents not described in detail in this specification are prior art known to those skilled in the art.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit defined by the appended claims and their equivalents.
