[0002] High and low voltage distribution cabinets are distribution equipment used for electric energy distribution, control, metering and cable connection in power supply systems. Their main function is to distribute and control electric energy under high voltage environment, distribute high voltage electric energy transmitted from power plants or upper substations, and then transmit it to lower substations or electrical equipment. At the same time, they protect and monitor the circuits to ensure the safe and stable operation of the power system.

[0003] High and low voltage distribution cabinets can be divided into many types. According to the installation method of the circuit breaker, they are divided into removable type (trolley type) and fixed type. The removable type is convenient for maintenance and operation. The circuit breaker trolley can be pulled out during maintenance to facilitate maintenance and replacement. According to the installation location, they are divided into indoor and outdoor. Indoor high-voltage distribution cabinets are mainly installed in indoor substations, distribution rooms and other places. They have high requirements on the environment and need to have good protection performance. Outdoor high-voltage distribution cabinets need to have good waterproof, dustproof, corrosion-resistant and other properties, and can adapt to various harsh outdoor environments.

[0004] At present, rubber strips are generally used for sealing between the cabinet doors and cabinet bodies of outdoor distribution cabinets. In the initial use, the rubber strips can play a certain sealing role, but with the passage of time and long-term exposure to outdoor environments, the rubber strips are prone to aging. The aged rubber strips will gradually lose their elasticity and sealing performance, and cracks, hardening, and brittleness will appear. Once the rubber strips are aged and fail, rainwater from the outside can easily enter the cabinet body. The intrusion of rainwater will cause serious damage to the electrical components in the cabinet, and may cause short circuits, leakage, equipment damage and other faults, greatly affecting the normal operation and service life of the distribution cabinet. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a high and low voltage distribution cabinet with waterproof and drainage function to solve the technical problem that the rubber strips used to seal the cabinet door and the cabinet body of the outdoor distribution cabinet in the prior art are prone to aging over a long period of time, causing external rainwater to easily enter the cabinet body and affect its internal electrical components.

DETAILED DESCRIPTION

[0030] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] The following describes an embodiment of the present invention based on its overall structure.

[0032] A high and low voltage distribution cabinet with waterproof and drainage function, such as Figure 1-10 As shown, it comprises a cabinet body 1, an inner door mechanism 2 is movably connected to the outer side of the cabinet body 1, and an outer door 3 located outside the inner door mechanism 2 is movably connected to the outer side of the cabinet body 1;

[0033] The outer side of the cabinet 1 is slidably connected with a sliding sealing waterproof frame 4, one end of the outer door 3 is fixed with a connecting plate 6, and the top and bottom of the connecting plate 6 are fixed with a rotating shaft 7 that is rotatably connected to the cabinet 1, and the top and bottom of one end of the connecting plate 6 are fixed with a flip driving plate 8, and the top and bottom of the cabinet 1 are both provided with a transmission mechanism 5, the transmission mechanism 5 includes a first adjustment plate 501 and a sliding hole 502, the sliding hole 502 is opened inside one side of the first adjustment plate 501, and the end of the flip driving plate 8 is fixed with a driving rod 9 extending to the inside of the sliding hole 502, and the transmission mechanism 5 also includes a second adjustment plate 505, an elastic sheet 508 and a push plate 507;

[0034] The second adjustment plate 505 and the cabinet 1 are slidably connected, and the horizontal positions of the second adjustment plate 505 and the first adjustment plate 501 are staggered, and the push plate 507 and the sliding sealing waterproof frame 4 are fixedly connected, and multiple groups of elastic sheets 508 are evenly arranged between the second adjustment plate 505 and the push plate 507;

[0035] A matching groove 14 matching with the sliding sealing waterproof frame 4 is provided on the inner side of the outer door 3, and the outer side of the sliding sealing waterproof frame 4 extends to the inside of the matching groove 14, and rubber strips are fixed on the outer side of the sliding sealing waterproof frame 4 and the inner side of the matching groove 14, and the rubber strips are squeezed against each other to form a sealing structure;

[0036] When the staff manually closes the outer door 3, the connecting plate 6 of the outer door 3 rotates between the rotating shaft 7 and the cabinet 1, and at the same time drives the flip driving plate 8 and the driving rod 9 to rotate, and then under the action of the transmission mechanism 5, the sliding sealing waterproof frame 4 slides on the outside of the cabinet 1, so that the sliding sealing waterproof frame 4 slides to the outside of the inner door mechanism 2;

[0037] When the outer door 3 and the inner door mechanism 2 are completely closed, the matching groove 14 on the inner side of the outer door 3 and the outer side of the sliding sealing waterproof frame 4 overlap with each other, and the overlapping position can block the gap between the inner door mechanism 2 and the cabinet body 1, effectively preventing the problem of external rainwater entering the cabinet body 1, and the overlapping position between them is fixed with a rubber strip, which can cause a certain degree of compression on the rubber strip, further improving the overall sealing effect, so that the overall waterproof effect is greatly improved;

[0038] The transmission mechanism 5 also includes a first rack 503, a gear 504 and a second rack 506. The first rack 503 is fixed on both sides of one end of the first adjustment plate 501, and the second rack 506 is fixed on both sides of one end of the second adjustment plate 505. The first rack 503 and the second rack 506 are meshed with each other through the gear 504, and the gear 504 and the cabinet 1 are rotatably connected through a movable shaft.

[0039] The inner door mechanism 2 includes a fixed inner door 201, a telescopic inner door 202, a hinge seat 203 and a movable connecting plate 204. The fixed inner door 201 and the telescopic inner door 202 are slidably connected, and the fixed inner door 201 and the cabinet body 1 are movably connected through the hinge seat 203. The telescopic inner door 202 and the inner side of the outer door 3 are movably connected through the movable connecting plate 204, and the movable connecting plate 204 and the telescopic inner door 202 and the outer door 3 are all movably connected through matching shafts.

[0040] When the inner door mechanism 2 is opened and closed along with the outer door 3, the telescopic inner door 202 can be passively retracted relative to the fixed inner door 201, and at the same time, under the action of the movable connecting plate 204, the problem of interference between the inner door mechanism 2 and the outer door 3 is avoided;

[0041] A drainage cover 10 is arranged on the top of the cabinet 1, and a drainage base 11 is fixed to the bottom of the cabinet 1. The top of the drainage cover 10 is inclined, and the four groups of outer side surfaces of the drainage base 11 are inclined at an angle, wherein the top of the drainage cover 10 is inclined at a certain angle, so that rainwater can be effectively discharged to avoid rainwater accumulation on the top of the cabinet 1. At the same time, the outer side surface of the drainage base 11 is also inclined to facilitate drainage and avoid the problem of rainwater accumulation.

[0042] See also Figure 5 , Fig. 9 and Fig.10 The transmission mechanism 5 also includes guide rods 509, and multiple groups of guide rods 509 are respectively fixed on both sides of one end of the first adjustment plate 501 and the second adjustment plate 505, and guide holes matching the guide rods 509 are opened inside the cabinet 1. By setting the above structure, the present invention has the guide rods 509 guiding the first adjustment plate 501 and the second adjustment plate 505 when they slide, making them more stable during the sliding process.

[0043] See also Figure 1 and Figure 2 A handle 13 and a lock body module 12 are respectively provided at the middle position of one end of the outer door 3. The present invention sets the above structure, wherein the handle 13 facilitates the opening and closing of the outer door 3, and the lock body module 12 plays a role in connecting and fixing the outer door 3 and the cabinet 1.

[0044] The working principle of the present invention is as follows: when in use, a concrete platform is first poured at the location where the power distribution cabinet is to be installed, wherein the area of ​​the concrete platform is larger than the area of ​​the drainage base 11, and then the whole cabinet 1 is installed on the concrete platform by expansion bolts, and at the same time, the electrical components are installed inside the cabinet 1 according to the installation specifications;

[0045] A drainage cover 10 is fixed on the top of the cabinet 1, and a drainage base 11 is fixed on the bottom. The top of the drainage cover 10 is inclined at a certain angle, so that rainwater can be effectively discharged to prevent rainwater from accumulating on the top of the cabinet 1. At the same time, the outer side of the drainage base 11 is also inclined to facilitate drainage and avoid the problem of rainwater accumulation.

[0046] The inner door mechanism 2 and the outer door 3 are used in sequence on the outer side of the cabinet body 1 for double sealing, wherein the inner door mechanism 2 is opened and closed along with the outer door 3. Specifically, the inner door mechanism 2 is composed of a fixed inner door 201 and a telescopic inner door 202. When the inner door mechanism 2 is opened and closed along with the outer door 3, the telescopic inner door 202 can be passively contracted relative to the fixed inner door 201. At the same time, under the action of the movable connecting plate 204, the problem of interference between the inner door mechanism 2 and the outer door 3 is avoided.

[0047] Furthermore, the two ends of the movable connecting plate 204 and the inner sides of the telescopic inner door 202 and the outer door 3 are all movably connected, thereby making the overall opening and closing operation smoother and avoiding interference.

[0048] When the staff manually closes the outer door 3, the connecting plate 6 of the outer door 3 rotates between the rotating shaft 7 and the cabinet 1, and at the same time drives the flip driving plate 8 and the driving rod 9 to rotate, and then under the action of the transmission mechanism 5, the sliding sealing waterproof frame 4 slides on the outside of the cabinet 1, so that the sliding sealing waterproof frame 4 slides to the outside of the inner door mechanism 2;

[0049] When the outer door 3 and the inner door mechanism 2 are completely closed, the matching groove 14 on the inner side of the outer door 3 and the outer side of the sliding sealing waterproof frame 4 overlap with each other, and the overlapping position can block the gap between the inner door mechanism 2 and the cabinet body 1, effectively preventing the problem of external rainwater entering the cabinet body 1, and the overlapping position between them is fixed with a rubber strip, which can cause a certain degree of compression on the rubber strip, further improving the overall sealing effect, so that the overall waterproof effect is greatly improved;

[0050] Specifically, when closing, the driving rod 9 rotates to drive the first adjustment plate 501 of the transmission mechanism 5 to slide, so that the first adjustment plate 501 drives the gear 504 to rotate through the first rack 503, and the gear 504 rotates to drive the second rack 506 and the second adjustment plate 505 to slide in the opposite direction, so that the second adjustment plate 505 can transmit the force to the push plate 507 through the multiple sets of elastic sheets 508, and then the push plate 507 pushes the sliding sealing waterproof frame 4 to slide;

[0051] Furthermore, when the sliding sealing waterproof frame 4 slides to the designated position, the outer door 3 and the inner door mechanism 2 are not completely closed. At this time, as the staff continues to flip and close the outer door 3 and the inner door mechanism 2, the second adjustment plate 505 compresses the multiple sets of elastic sheets 508, and the compressed elastic sheets 508 exert a part of the elastic force on the push plate 507 and the sliding sealing waterproof frame 4;

[0052] That is to say, when the outer door 3 and the inner door mechanism 2 are completely closed and then locked with the cabinet 1 through the lock body module 12, the sliding sealing waterproof frame 4 can always form a tight fit with the matching groove 14 of the outer door 3 under the elastic force of the elastic sheet 508, thereby ensuring that the sliding sealing waterproof frame 4 does not loosen due to external factors, greatly improving the overall sealing and waterproof performance, and having a better use effect.

[0053] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
