DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments.

[0026] With reference to Figures 1-6 The present utility model discloses a novel power grid distribution cabinet, which comprises a cabinet body 1, a mounting frame 2 for installing electrical elements is arranged in the cabinet body 1, a cabinet door 3 is arranged at the front end of the cabinet body 1, an inner blocking frame 5 is arranged at the front end of the inner side of the cabinet body 1, a sealing groove 7 is formed at the front end of the inner side of the inner blocking frame 5, a sealing gasket 6 is arranged in the sealing groove 7, the sealing gasket 6 is telescopically installed in the sealing groove 7 through a spring assembly 9, an outer blocking frame 4 corresponding to the sealing gasket 6 is arranged on the rear end face of the cabinet door 3, and the outer blocking frame 4 and the inner blocking frame 5 are both made of heat insulation materials.

[0027] The cabinet door 3 is connected with the cabinet body 1 through a hinge, and the sealing gasket 6 is made of a rubber strip. Since the aging of rubber is mainly related to factors such as exposure to sunlight, temperature and mechanical stress, the sealing gasket 6 is installed on the inner side of the cabinet body 1, which can effectively reduce the exposure to sunlight and slow down the aging.

[0028] In addition, the outer blocking frame 4 and the inner blocking frame 5 can be made of a heat-resistant laminated board composed of a skeleton-shaped glass fiber and a high-heat-resistant composite material. Since the heat received by the sealing gasket 6 mainly comes from the cabinet body 1 and the cabinet door 3, and the heat on the cabinet body 1 and the cabinet door 3 mainly comes from the heat generated by the internal electrical appliances and the external sunlight, the heat received by the sealing gasket 6 can be effectively blocked by the outer blocking frame 4 and the inner blocking frame 5 supported by the heat insulation board, further slowing down the aging speed of the sealing gasket 6.

[0029] The sealing gasket 6 is installed in the sealing groove 7 through the spring assembly 9, which can also reduce the situation that the sealing gasket is fixedly installed in the traditional power distribution cabinet, and the sealing gasket and the cabinet door mainly rely on rigid extrusion to maintain sealing. In this application, the sealing gasket 6 and the outer blocking frame 4 are in elastic extrusion contact, and under the premise of maintaining the sealing effect of the sealing gasket 6 and the outer blocking frame 4, the pressure between the sealing gasket 6 and the outer blocking frame 4 is reduced by using a corresponding specification spring, thereby reducing the deformation degree of the sealing gasket 6 and further reducing the mechanical stress inside the rubber sealing gasket 6, and further slowing down the aging speed of the sealing gasket 6.

[0030] The sealing gasket 6 is provided with a sealing gasket bottom plate 8 on the end face close to the sealing groove 7, and the spring assembly 9 is fixedly installed on the sealing gasket bottom plate 8.

[0031] The sealing gasket 6 itself is made of elastic material, and when directly connected with the spring assembly 9, more spring assemblies 9 are needed to maintain good sealing contact between each position and the outer blocking frame 4, but the cost is high. After using the sealing gasket bottom plate 8, the sealing gasket 6 is installed on the sealing gasket bottom plate 8, the sealing gasket bottom plate 8 is a rigid part, the spring assembly 9 supports the sealing gasket bottom plate 8, the sealing gasket bottom plate 8 supports the sealing gasket 6, and the sealing gasket 6 is tightly attached to the outer blocking frame 4.

[0032] The spring assembly 9 includes an extension column 91, one end of the extension column 91 is fixedly connected with the sealing gasket bottom plate 8, the other end is provided with a sliding block 93, the front end face of the sealing groove 7 is provided with an extension hole 11, the sliding block 93 is slidingly installed in the extension hole 11, and the outside of the extension column 91 is provided with a spring 92, and the spring 92 is located between the sealing gasket bottom plate 8 and the extension hole 11.

[0033] The pressure between the sealing gasket 6 and the outer frame 4 and the degree of deformation of the sealing gasket 6 are mainly determined by the spring force of the spring 92. When selecting the specification of the spring 92, the spring force of the spring 92 can mainly ensure that the sealing gasket 6 is tightly attached to the outer frame 4, and at the same time, the outer frame 4 does not deform severely.

[0034] When the cabinet door 3 is closed, the cabinet door 3 drives the outer frame 4 to push the sealing gasket 6, and the sealing gasket 6 slides along the axis direction of the telescopic column 91 together with the sealing gasket base plate 8 until the cabinet door 3 is closed.

[0035] The sealing gasket 6 and the sealing gasket base plate 8 are connected by suction.

[0036] The suction connection is a detachable connection relationship, which is convenient for replacing the sealing gasket 6. In the prior art, the sealing gasket is usually pressed and embedded into a groove in a slotting manner. This manner not only takes time and effort during installation, but also causes deformation of the sealing gasket itself. The use of suction connection does not have these problems.

[0037] A permanent magnet 12 is embedded on the end face of the sealing gasket 6 close to the sealing gasket base plate 8, and a magnetic suction plate 10 corresponding to the permanent magnet 12 is arranged on the end face of the sealing gasket base plate 8 close to the sealing gasket 6.

[0038] The permanent magnet 12 and the magnetic suction plate 10 are multiple and uniformly distributed on the sealing gasket 6 and the sealing gasket base plate 8. The magnetic suction plate is a magnetic material, and the permanent magnet 12 is attracted to the magnetic suction plate, thereby fixing the sealing gasket 6 on the sealing gasket base plate 8. The sealing gasket 6 is convenient to disassemble and replace.

[0039] The permanent magnet 12 is provided with an outer shell 13, and the outer shell 13 is embedded and installed in the sealing gasket 6.

[0040] The magnetic suction plate 10 and the outer shell 13 are both soft magnetic material structures.

[0041] The outer shell 13 is a sink structure, and the soft magnetic material structure of the outer shell 13 and the magnetic suction plate 10 can form a closed shielding structure, so that the magnetic field lines emitted by the permanent magnet 12 are mainly distributed in the outer shell 13 and the magnetic suction plate 10, thereby reducing the influence of the permanent magnet 12 on external electrical elements.

[0042] Working principle: when in use, the electrical elements for power distribution equipment are installed in the cabinet body 1 through the mounting frame 2. After the cabinet door 3 is closed, the outer frame 4 is attached to the sealing gasket 6, and the sealing gasket 6 is fully attached to the outer frame 4 under the support of the spring assembly 9.

[0043] When the sealing gasket 6 needs to be replaced, the sealing gasket 6 is directly pulled to separate the permanent magnet 12 from the magnetic suction plate 10, and then a new sealing gasket 6 is replaced, and the new permanent magnet 12 is attracted to the original magnetic suction plate 10.

[0044] The above merely describes a preferred embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent replacements or changes to the technical scheme and the inventive concept of the present application within the technical scope disclosed by the present application, which should be covered by the protection scope of the present application.
