Description

Technical Field

[0001] The utility model belongs to the technical field of coal mine electromechanical and electrical control cabinets, in particular to a coal mine electromechanical and electrical control cabinet. Background Art

[0002] Coal mining requires the use of a large number of electromechanical and electrical equipment, which are used to control the equipment during the mining process. Due to the large number of types and quantities of equipment required during coal mining, in order to better control the operation of equipment, the existing technology uses electrical control cabinets installed in the mine to achieve control of equipment. For example, pump stations and motor rooms all require electrical control cabinets to operate.

[0003] Specifically, the electrical components that control the operation of the equipment are integrated and installed in the electrical control cabinet to facilitate the control of the equipment. Therefore, during actual operation, the operator only needs to control the corresponding electrical components in the electrical control cabinet to control the working equipment.

[0004] During mining, electrical control cabinets operate underground in a highly hazardous environment, characterized by high temperatures and a high risk of combustion and explosion from flammable gases such as gas. Furthermore, the operation of electrical control cabinets, especially high-voltage ones, is particularly hazardous. Consequently, conventional electrical control cabinets lack protective and explosion-proof designs, leading to explosions during operation. For example, an operator mistakenly closing a switch could cause an explosion. The resulting fragments have high kinetic energy, making them highly susceptible to injury. Furthermore, if these high-speed fragments travel long distances to the coal mining area and collide to create sparks, they pose a significant safety hazard to underground mine operations.

[0005] Specifically, during the actual production process, an explosion fragment of the electric control cabinet splashed outside the electric control room, generating sparks and causing a fire in the mine.

[0006] Therefore, in actual work, there is an urgent need to provide explosion-proof protection for distribution cabinets in mines, especially in the electrical control room near the working area. Utility Model Content

[0037] Example 1

[0038] like Figure 1-5 As shown, a coal mine electromechanical electrical control cabinet includes an electrical control cabinet body 1. The electrical control cabinet body 1 is an electrical control cabinet conventionally used in the prior art. The main structure includes a cabinet body and a cabinet door hingedly mounted on the cabinet body, as well as electrical components installed in the cabinet body, buttons for controlling start and stop and installed on the outside of the cabinet body and other components.

[0039] In order to reduce the splash of explosion fragments and avoid sparks caused by explosion fragments in the event of an electrical control cabinet failure such as high-temperature deactivation or an explosion caused by an operational error such as a closing error, the upper and lower ends of the electrical control cabinet body 1 are respectively equipped with electrical cabinet explosion-proof mechanisms (the upper and lower electrical cabinet explosion-proof mechanisms are symmetrically arranged).

[0040] Specifically, the explosion-proof mechanism of the electrical cabinet includes an outer frame base 3 fixedly mounted on the electrical control cabinet body 1 (a plurality of T-shaped connection bases 31 are fixedly connected to the inner side wall of the outer frame base 3, and the T-shaped connection bases 31 are fastened to the electrical control cabinet body 1 by a plurality of bolts). The outer frame base 3 is installed away from the cabinet door position on the cabinet body to double the subsequent cabinet door opening.

[0041] The outer frame seat 3 is assembled and connected with a number of explosion-proof components distributed around the electrical control cabinet body 1. Specifically, the front and rear sides and the left and right sides of the outer frame seat 3 are respectively hingedly mounted with explosion-proof components.

[0042] The specific structure of the explosion-proof component is:

[0043] The explosion-proof component includes several explosion-proof guard rods 21 hinged on the outer frame seat 3, and the hinge method is: several hinge ports 31 are opened on the outer frame seat 3, and the explosion-proof guard rod 21 includes a vertical rod portion, and the upper end of the vertical rod portion is integrally formed with a hinged rod portion hinged in the hinge port 31; a hinge shaft is rotatably connected in the hinge port 31, and a fixed seat 211 fixedly connected to the hinge shaft is fixedly connected to the hinge rod portion.

[0044] A blocking net 22 is fixedly connected between the explosion-proof guard bars 21; specifically, the blocking net 22 is rectangular in shape; the blocking net 22 is a metal mesh made of metal material, and the blocking net 22 is fixedly connected between the vertical parts.

[0045] During operation, the cabinet is surrounded by four explosion-proof components. If a working component in the cabinet explodes at high temperature, the fragments and debris generated by the explosion will be isolated in the explosion-proof guard bar 21-blocking net 22 structure under the enclosure of the explosion-proof components.

[0046] Since the explosion-proof guard bar 21 has a high impact strength, it can withstand a certain explosion impact force.

[0047] Example 2

[0048] like Figure 1-5 As shown, based on the structure of Example 1, the explosion-proof component of this embodiment also includes a plurality of pulling spring structures respectively pulled at the top position of the explosion-proof guard rod 21, and the pulling spring structure is used to facilitate the operation of the electric control cabinet, such as opening the cabinet door or subsequent maintenance of the cabinet body.

[0049] Specifically, the tension spring structure includes a fixed column 41 fixedly connected to the top of the outer frame seat 3. The upper end of the fixed column 41 is fixedly connected to a tension spring 42 that is pulled at the top of the explosion-proof protective rod 21. Specifically, the upper end of the fixed column 41 is threadedly connected to a spring seat 411, and the upper end of the tension spring 42 is fixedly connected to the spring seat 411.

[0050] Under normal circumstances, since the top of the hinged explosion-proof guard bar 21 is affected by the pulling spring 42, the four explosion-proof components are always away from the cabinet and in a tilted state. The operator can fully expose the cabinet for easy operation by flipping it upward with a little force.

[0051] When explosion protection is required, the operator pulls down and flips the explosion-proof assembly (all explosion-proof guardrails 21 on the explosion-proof assembly are fixed by a metal screen 22 of a certain thickness, so all explosion-proof guardrails 21 form a whole), and the explosion-proof assembly switches from the tilted state to the vertical state. The adjacent explosion-proof assemblies are then locked. Specifically, the coal mine electromechanical electrical control cabinet also includes a gusset assembly for locking adjacent explosion-proof assemblies. When the adjacent explosion-proof assemblies are flipped to the vertical protection state, the gusset assembly locks the adjacent explosion-proof assemblies to maintain the explosion-proof assemblies in the vertical protection state.

[0052] The specific structure of the angle plate assembly is:

[0053] The angle plate assembly includes an L-shaped angle plate 23, one end of which is mounted on the lower end of the explosion-proof guard bar 21 on one side (the square explosion-proof assembly). The other end of the L-shaped angle plate 23 is removably mounted on the lower end of the explosion-proof guard bar 21 at the adjacent angle. In other words, the two ends of the L-shaped angle plate 23 are locked between the explosion-proof guard bars 21 on both sides of the cabinet corner. The four angle plate assemblies sequentially lock the four explosion-proof assemblies, maintaining the four explosion-proof assemblies in a locked and vertical protective state.

[0054] Correspondingly, the other end of the L-shaped angled plate 23 defines a rectangular mounting hole 231. A locking screw 232, threadedly connected to the lower end of the explosion-proof guardrail 21 at the corresponding connection location, passes through this rectangular mounting hole 231. A nut is threadedly attached to this locking screw 232. Once the explosion-proof assembly is flipped vertically, the L-shaped angled plate 23 secures the adjacent explosion-proof assembly, maintaining the vertical protective position.

[0055] Example 3

[0056] like Figure 1-5 As shown, based on the structure of Example 1, this embodiment follows the existing method to prevent the moisture on the wet ground in the mine from affecting the electrical components. The bottom of the above-mentioned electrical control cabinet body 1 is fixedly connected with a frame-shaped support base 4, and the top of the frame-shaped support base 4 is fixedly installed on the gas control cabinet body through a number of I-shaped connecting seats.

[0057] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
