Description

Technical Field

[0001] This utility model relates to the field of urban rail transit technology, specifically to an electrical grid cabinet with a locking structure for urban rail transit. Background Technology

[0002] Urban rail transit power grid cabinets, also known as switch cabinets or distribution cabinets, are electrical devices used in power systems, primarily for receiving and distributing electrical energy. They integrate various electrical components, such as circuit breakers, disconnect switches, grounding switches, current transformers, voltage transformers, and surge arresters, to achieve control, protection, and monitoring functions for the power system. Power grid cabinets are widely used in substations, power plants, industrial and mining enterprises, and urban power distribution networks. A power grid cabinet is a storage cabinet used to house transformers and electrical control switches related to electrical equipment. It typically has fixed or movable mounting racks installed inside, and the corresponding electrical components are then fixed to these racks using bolts, thus achieving unified and centralized management.

[0003] This utility model, disclosed in publication number CN221633096U, is a power grid cabinet with a locking structure, relating to the field of electrical distribution cabinets. The power grid cabinet with the locking structure includes a cabinet body and an electrical switch. A fixing frame is installed inside the cabinet body; the fixing frame includes a support plate. The electrical switch is fixed to the outer wall of the support plate by bolts. Rotating bars are provided on both sides of the support plate, and a locking bar for locking the electrical switch is installed between the two sets of rotating bars. A fixing rod is provided on the back of the rotating bars, and the fixing rod is movably engaged with the support plate. The current electrical switchgear with a locking structure presses two sets of movable blocks towards the center, causing the locking pins to retract into the fixed rod. Then, the rotating bar is flipped upwards, causing the top block on the inner side of the locking bar to abut against the electrical switch. The fixed rod enters the slot. At this point, the two sets of movable blocks are released, and under the action of the locking spring, the two sets of locking pins enter the inner wall of the slot for fixation, thus locking the electrical switch. However, the above device has a relatively simple structure and cannot effectively dissipate the heat generated during the operation of the electrical switchgear. Therefore, we propose an electrical switchgear with a locking structure for urban rail transit. Utility Model Content

[0007] Preferably, support bases are provided at the four corners of the lower surface of the power grid cabinet, and rubber blocks are provided at the lower ends of the four support bases to enhance the stability of the power grid cabinet.

[0008] Preferably, the power grid cabinet has four sets of heat dissipation holes on both the left and right sides, and each heat dissipation hole is equipped with a dustproof mesh to dissipate heat from the power grid cabinet.

[0009] Preferably, the power grid cabinet has four sets of insertion strips on both the left and right sides inside, and the four sets of mounting plates have matching mounting slots on both the left and right sides, which can facilitate the installation of the mounting plates.

[0010] Preferably, the locking assembly includes a positioning frame, which is fixedly installed on the upper left side of the baffle. A plug is inserted into the upper end of the positioning frame, and the left side of the plug is set as an oblique structure. A matching slot is opened at the upper front side of the power grid cabinet to fix the baffle.

[0011] Preferably, the lower end of the insert block is provided with a positioning piece, and a support spring is provided inside the positioning frame, with the upper end of the support spring connected to the positioning piece, so that the insert block can be easily inserted into the slot.

[0012] Preferably, a connecting strip is provided on the right side of the positioning piece, and a matching sliding groove is provided on the right side of the positioning frame and the surface of the baffle. An adjustment block is provided at the right end of the connecting strip to adjust the position of the insertion block and facilitate opening the baffle.

[0013] This utility model has at least the following beneficial effects:

[0014] By opening four sets of heat dissipation holes on the left and right sides of the power grid cabinet, the heat dissipation area can be effectively increased, the heat dissipation efficiency can be improved, and the temperature inside the power grid cabinet can be kept within a safe range. The dustproof net inside the heat dissipation hole can effectively block the entry of external dust and protect the power equipment from dust damage. Good heat dissipation and dust prevention measures can reduce the thermal stress and mechanical wear of the power equipment, thereby extending the service life of the equipment.

[0015] With the support base, the rubber block has good elasticity and cushioning performance, which can effectively absorb and disperse the vibration and impact generated by the operation of the internal equipment of the power grid cabinet, thereby reducing noise transmission and creating a quieter working space for the surrounding environment. The combination of the support base and the rubber block can reduce the hard collision or friction that may occur when the power grid cabinet is in direct contact with the ground, protect the cabinet and its internal precision components from damage, and extend the service life of the equipment.

[0021] 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.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a power grid cabinet with a locking structure for urban rail transit, comprising power grid cabinet 1:

[0023] The power grid cabinet 1 has four sets of mounting plates 5 installed inside. A baffle 7 is hinged to the right side of the front surface of the power grid cabinet 1, and a handle 8 is provided on the front side of the baffle 7. A locking component is provided on the upper left side of the baffle 7.

[0024] Support bases 2 are installed at the four corners of the lower surface of the power grid cabinet 1, and rubber blocks are installed at the lower ends of the four sets of support bases 2. The rubber blocks have good elasticity and cushioning performance, which can effectively absorb and disperse the vibration and impact generated by the operation of the internal equipment of the power grid cabinet 1, thereby reducing noise transmission and creating a quieter working space for the surrounding environment. The combination of support bases 2 and rubber blocks can reduce the hard collisions or friction that may occur when the power grid cabinet 1 is in direct contact with the ground, protect the cabinet and its internal precision components from damage, and extend the service life of the equipment.

[0025] The power grid cabinet 1 has four sets of heat dissipation holes 3 on both the left and right sides, and each heat dissipation hole 3 is equipped with a dustproof net 4. By opening four sets of heat dissipation holes 3 on the left and right sides, the heat dissipation area can be effectively increased, the heat dissipation efficiency can be improved, and the temperature inside the power grid cabinet 1 can be kept within a safe range. The dustproof net 4 inside the heat dissipation hole 3 can effectively block the entry of external dust and protect the power equipment from dust damage.

[0026] The power grid cabinet 1 has four sets of plug strips 6 on both the left and right sides inside, and the four sets of mounting plates 5 have matching mounting slots on both the left and right sides. The mounting plates 5 can be installed inside the power grid cabinet 1 by matching the plug strips 6 with the mounting slots.

[0027] The locking assembly includes a positioning frame 9, which is fixedly installed on the upper left side of the baffle 7. A plug 10 is inserted into the upper end of the positioning frame 9, and the left side of the plug 10 is set as an angled structure. A matching slot 11 is opened at the upper front side of the power grid cabinet 1. When the baffle 7 is closed, the plug 10 at the upper end of the positioning frame 9 is inserted into the slot 11 to fix the baffle 7. The angled structure of the plug 10 can be pressed when the baffle 7 is closed, causing the plug 10 to move into the positioning frame 9, thereby facilitating the closing of the baffle 7.

[0028] The lower end of the insert block 10 is provided with a positioning piece 12, and the positioning frame 9 is provided with a support spring 13. The upper end of the support spring 13 is connected to the positioning piece 12. After the baffle 7 is reset, the support spring 13 can drive the positioning piece 12 and the insert block 10 to move, thereby driving the insert block 10 to be inserted into the slot 11 and fixing the baffle 7.

[0029] A connecting strip 14 is provided on the right side of the positioning piece 12, and a matching sliding groove is provided on the right side of the positioning frame 9 and the surface of the baffle 7. An adjusting block 15 is provided on the right end of the connecting strip 14. By moving the adjusting block 15, the positioning piece 12 can be moved through the connecting strip 14, thereby causing the insert block 10 to disengage from the slot 11, thus releasing the fixation of the baffle 7, and making it convenient to open the baffle 7 by pulling the handle 8.

[0030] Working principle: After the mounting plate 5 is installed in the power grid cabinet 1 through the insert 6, the baffle 7 is closed. When closed, the inclined structure of the insert 10 causes the insert 10 to be pressed and moved into the positioning frame 9, so that the baffle 7 can be closed. Then, the elastic force of the support spring 13 drives the insert 10 to be inserted into the slot 11 opened in the power grid cabinet 1, which fixes the baffle 7. When it is necessary to open the baffle 7, the position of the adjusting block 15 is moved, and the positioning piece 12 is moved through the connecting strip 14, so that the insert 10 is disengaged from the slot 11, releasing the fixation of the baffle 7, and making it easy to pull the handle 8 to open the baffle 7.
