Description

Technical Field

[0001] The utility model belongs to the technical field of control cabinets, in particular to an electric control cabinet. Background Art

[0002] A control cabinet is a device that assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to electrical wiring requirements. Its layout should meet the requirements for normal operation of the power system, be easy to repair, and not endanger the safety of people and surrounding equipment. During normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches. In case of faults or abnormal operation, the circuit can be cut off or an alarm can be given with the help of protective electrical appliances. Various parameters in operation can be displayed with the help of measuring instruments, and certain electrical parameters can be adjusted. It can also prompt or send signals when deviating from the normal working state. It is often used in various power generation, distribution and substations. However, during the use of the electrical control cabinet, the electrical components installed inside it will generate a large amount of heat energy. The heat cannot be discharged quickly, which can easily cause the temperature of the electrical control cabinet to rise, thereby affecting the normal use of the electrical control cabinet. In addition, the heat will gather upward in the electrical cabinet. The heat dissipation vents on both sides of the common electrical cabinet cannot dissipate heat quickly, and on rainy days, rainwater will enter the cabinet through the heat dissipation vents on both sides of the cabinet. Therefore, the present application proposes an electrical control cabinet. Utility Model Content

[0004] Furthermore, hydraulic rods are fixedly installed at the four corners of the cabinet top, and the telescopic ends of the four hydraulic rods are fixedly connected to the bottom of the top cover, and the bottom of the top cover can fit tightly with the tops of the four sides of the top cover.

[0005] Furthermore, water outlets are provided at the middle positions of the bottoms of both sides of the top cover, and the top of the cabinet is arranged as an inclined surface with a higher middle and lower sides.

[0006] Furthermore, a first dustproof net is fixedly installed at the openings at the top and bottom ends of each connecting pipe, and a second dustproof net is fixedly installed at the openings on both sides of the top cover.

[0007] Furthermore, the top end of each connecting tube is located at the same horizontal plane, and when the bottom end of the top cover contacts the top end of the top cover, the top end of each connecting tube contacts the bottom end of different top covers.

[0008] Furthermore, the width of the top cover is the same as that of the top cover, and both ends of the inclined surface of the top cover extend over both sides of the top cover.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The heat in the cabinet can be transported to the top cover through the second cooling fan in the connecting pipe, and then the heat in the top cover can be discharged under the action of the two first cooling fans. By controlling the hydraulic rod to push the top cover upward, the heat dissipation in the top cover can be further accelerated, and rainwater can be prevented from entering the cabinet on rainy days. Once rainwater enters the top cover, the rainwater will flow along the inclined surface of the top of the cabinet and be discharged from the water outlets at the bottom of both sides of the top cover.

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] Depend on Figure 1-5 The utility model includes a cabinet 1, a top cover 3 is fixedly installed on the top of the cabinet 1, the top ends of both sides of the top cover 3 are set to be triangles, an inverted V-shaped top cover 9 which can move up and down is set on the top of the top cover 3, and the shape of the top cover 9 is adapted to the shape of the top ends of the top cover 3, a plurality of neatly arranged connecting pipes 7 are evenly and fixedly installed at the middle position of the top of the cabinet 1, the bottom end of each connecting pipe 7 is connected to the inner cavity of the cabinet 1, a second cooling fan 8 is fixedly installed at the middle position inside each connecting pipe 7, through openings 4 are opened at the middle positions on both sides of the top cover 3, a first cooling fan 5 is fixedly installed in the two through openings 4, the top end of the connecting pipe 7 is much higher than the top of the cabinet 1, so that a small amount of rainwater entering the top cover 3 from the through opening 4 cannot enter the interior of the cabinet 1 through the opening at the top end of the connecting pipe 7.

[0020] At the same time, hydraulic rods 10 are fixedly installed at the four corners of the top of the cabinet 1, and the telescopic ends of the four hydraulic rods 10 are fixedly connected to the bottom of the top cover 9. The bottom of the top cover 9 can be tightly fitted with the tops of the four sides of the top cover 3. By controlling the hydraulic rods 10, the top cover 9 can be pushed to rise in height, so that the bottom of the top cover 9 is separated from the top of the top cover 3. In this way, in conjunction with the two first cooling fans 5, the heat entering the top cover 3 can be quickly discharged.

[0021] In addition, water outlets 6 are provided at the middle positions of the bottoms of both sides of the top cover 3, and the top of the cabinet 1 is set as a slope with a high middle and low sides, so that rainwater entering the top cover 3 will slide along the slope of the top of the cabinet 1 to both sides, and finally be discharged from the water outlets 6 at the bottoms of both sides of the top cover 3.

[0022] In addition, a first dustproof net 11 is fixedly installed at the openings at the top and bottom ends of each connecting pipe 7, and a second dustproof net is fixedly installed at the openings 4 on both sides of the top cover 3. The first dustproof net 11 can prevent dust from entering the connecting pipe 7, thereby preventing dust from adhering to the blade surface of the second cooling fan 8, and the second dustproof net can prevent dust from adhering to the first cooling fan 5.

[0023] Furthermore, the top end of each connecting tube 7 is located in the same horizontal plane. When the bottom end of the top cover 9 contacts the top end of the top cover 3, the top end of each connecting tube 7 contacts the bottom end of a different top cover 9, thereby preventing the top end of the connecting tube 7 from obstructing the connection between the bottom end of the top cover 9 and the top end of the top cover 3.

[0024] In addition, the width of the top cover 9 is the same as that of the top cover 3, and both ends of the inclined surface of the top cover 9 extend over both sides of the top cover 3, so that the top cover 9 can cover the top of the top cover 3, and the protruding part of the top cover 9 can play a role in keeping out rain.

[0025] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0026] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
