BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Figure 1 It is a front view of the front of the utility model;

[0022] Figure 2 It is a side view of the present utility model. DETAILED DESCRIPTION

[0023] The technical solution of the present invention is described in detail below with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the embodiments.

[0024] A shield machine power control cabinet, such as Figure 1 As shown, the cabinet comprises a cabinet body 1, a shielding portion 2, and a base. The cabinet body 1 is provided with at least one set of doors 101, which are double-door structures. The width of a single door in this double-door structure is no greater than 500 mm, which saves space occupied by the cabinet doors and ensures easy maintenance of the cabinet. The shielding portion 2 is provided at the edge of the top surface of the cabinet body 1 to shield the cabinet surface. A base is provided at the bottom of the cabinet body 1 to support the cabinet body 1.

[0025] Specifically, the cabinet doors 101 can be set on one side or both sides of the cabinet body 1, and there is no restriction here. The cabinet doors 101 can all be opened outward. In order to save space, the cabinet doors 101 on each side can be divided equally according to the overall width of the cabinet body 1, and divided into several groups of cabinet doors 101 that open opposite each other. Therefore, the space inside the cabinet can be fully utilized, and as many devices as possible can be arranged inside the cabinet body 1 through each group of openable cabinet doors 101, saving trolley space; when power supply copper bars are arranged inside the cabinet body 1, the equipment can be shared. The provision of several groups of cabinet doors 101 also makes it more convenient to take and put the equipment, saving operation time.

[0026] A handle 102 is generally provided on the opposite side of the cabinet door 101 to facilitate the operator to open and close the cabinet door 101.

[0027] In order to prevent water from entering the cabinet 1, a shielding portion 2 is provided on the edge of the top surface of the cabinet 1 to shield the cabinet surface. Figure 2 The shielding portion 2 can be arranged around the top surface, or can be arranged only at the corresponding positions of the front and rear sides of the cabinet body 1, as shown. Figure 2 As shown, the shielding portion 2 is constructed as a convex portion protruding from the front and rear sides. The overall length of the convex portion is equal to the width of the cabinet body 1, thereby shielding the cabinet door 101 and effectively preventing liquid from seeping through the gap of the cabinet door 101. At the same time, the door gap of the cabinet door 101 can also be sealed, such as by installing a sealing strip or applying glue.

[0028] In order to further prevent liquid from flowing through the cabinet door 101 and into the cabinet body 1, the top edge of the shielding portion 2 is constructed with a chamfer. When there is liquid on the top surface of the cabinet body 1, the chamfer can guide the liquid to the edge of the protrusion and will not flow through the bottom of the protrusion and into the cabinet door 101, thereby protecting the equipment in the cabinet from damage and reducing equipment failures.

[0029] The shielding portion 2 can be installed in a detachable manner or integrally with the cabinet body 1. As can be imagined, if the shielding portion 2 is installed in a detachable manner, a certain installation gap will inevitably be created, thereby reducing the waterproof effect. Therefore, the structure in which the shielding portion 2 is integrally formed with the cabinet body 1 can effectively block liquids and further enhance the waterproof protection of the equipment within the cabinet body 1. Here, the integrally formed structure can be formed by bending the shielding portion 2 and the cabinet body 1 from the same piece of steel plate, and no specific restrictions are set here.

[0030] The top of the control cabinet may also be provided with a lifting part 3, which is evenly arranged on the top surface of the cabinet body 1. Each lifting part 3 is provided with a lifting hole 301 for the lifting device to lift the control cabinet. Generally speaking, the lifting part 3 is arranged on the top surface of the cabinet body 1 in any form as long as it can ensure uniform force during lifting. As one embodiment, there are a total of 6 lifting parts 3, 3 of which are arranged on the front edge of the top surface of the cabinet body 1, and the other 3 are arranged on the rear edge of the top surface of the cabinet body 1. All lifting parts 3 can be steel plates with lifting holes 301, which are fixed to the top surface of the cabinet body 1 by welding to ensure the reliability and stability of the lifting. They can also be installed by fastening with bolts to ensure the strength of the lifting part 3.

[0031] The equipment in the cabinet is prone to generate heat when working, so an exhaust fan 4 is constructed on the cabinet door 101 to discharge the hot air in the cabinet and avoid malfunction caused by overheating of the equipment outlet line.

[0032] In order to further reduce the temperature inside the cabinet, an air intake grille and a filter 5 are constructed on the lower side of the cabinet door 101. Therefore, while the exhaust fan 4 discharges the hot air inside the cabinet, the air intake grille and the filter 5 can draw in the cold air outside the cabinet, thus forming an internal heat circulation, continuously replacing the hot air inside the cabinet, and further enhancing the cooling effect.

[0033] The base includes a bottom plate 501 and a panel 502. The panel 502 is arranged on the front side and the rear side. The bottom plate 501 connects the front and rear panels 502. The space below the cabinet 1 formed between the two side panels 502 can be used for wiring. The panel 502 includes a support portion 5021 and an opening portion 5022. The support portion 5021 is arranged longitudinally and aligned with the cabinet door 101. An opening portion 5022 is formed between adjacent support portions 5021. The opening portion 5022 can be convenient for operators to operate when arranging wiring. When wiring is not required, the opening portion 5022 can be horizontally covered by a protective plate. When designing the overall structure of the shield machine, more wiring holes will be left, corresponding to the space of the cabinet base frame, to facilitate the cables to reach the required wiring position from the cabinet.

[0034] The bottom plate 501 is constructed from spliced or stamped steel plates, eliminating the sharp corners of angle steel and resulting in a smooth surface. The panel 502 is welded to the cabinet 1, and to the bottom plate 501, using angle steel. This connection effectively prevents damage to the cables from vibrations caused by the sharp corners of the bottom plate 501, thereby reducing construction risks, minimizing construction failures, and improving construction efficiency.

[0035] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes may be made to it in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims.
