Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a power distribution cabinet for coal mines which is easy to maintain. Background Art

[0002] The distribution control cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the final equipment of the distribution system and is a general term for the motor control center. The distribution cabinet is mostly placed in outdoor places. As an electrical control component, the distribution control cabinet has the main function of providing a fixed space for the electrical components fixed inside it. When the electrical energy is transmitted to the electrical components of the control cabinet, the electrical components transmit the electrical energy to the inside of the external power receiving components, completing the electrical control of the external control components.

[0003] Power distribution cabinets are often used on-site in coal mines, and they need to be regularly inspected and maintained to ensure their normal operation.

[0004] After searching, a patent publication number CN213136716U, which mentions an explosion-proof box for coal mine electrical equipment that is easy to maintain, states that "before maintenance, workers should first check whether the indicator light is in the maintenance-required state, and then operate the main switch to cut off the power to the device. This can make maintenance safer for workers. If a worker's tools are damaged during construction, the worker can hold the handle to open the box door and remove spare tools from the second baffle, avoiding accidents caused by operator errors. The explosion-proof plate strengthens the explosion-proof capability of the device."

[0005] However, the above solution still has certain shortcomings in actual use. The above solution requires staff to drill into the box to maintain the components. However, due to the small internal space of the box, daily maintenance or inspection work is very difficult, which increases the workload of the staff, resulting in the entire inspection process being time-consuming and labor-intensive, which is not conducive to the inspection work of maintenance personnel.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-5 The utility model discloses a power distribution cabinet for coal mines that is easy to maintain, including a cabinet structure 1 and a component mounting rack 204. An expansion structure 2 is provided on the inner side of the cabinet structure 1, and the component mounting rack 204 is located inside the expansion structure 2.

[0026] The cabinet structure 1 includes a cabinet panel 101 . The cabinet panel 101 is located at the top of the unfolded structure 2 . A cabinet door 102 is hinged to the front side of the cabinet panel 101 .

[0027] The unfolding structure 2 includes a side plate 201 , a pushing base 203 is fixedly mounted on the bottom end of the side plate 201 , and the bottom end of the component mounting frame 204 is movably engaged with the top end of the pushing base 203 .

[0028] The pushing base 203 includes a mounting base 205, a driving device 206 is arranged inside the mounting base 205, a moving block 207 is fixedly installed on the movable end of the driving device 206, the top of the moving block 207 is fixedly connected to a connecting plate 208, and the other end of the connecting plate 208 is fixedly connected to the inner side of the cabinet panel 101.

[0029] The driving device 206 includes a driving box 209, the inner wall of which is rotatably connected to a driving turntable 210 through a built-in power supply, an eccentric pile 211 is fixedly installed on the top of the driving turntable 210, and a movable sleeve 212 is movably sleeved on the outer side of the eccentric pile 211, and a push rod 214 is fixedly connected to the outer side of the movable sleeve 212, and the push rod 214 is fixedly connected to the side end of the moving block 207.

[0030] By setting up the unfolding structure 2 and utilizing the driving device 206 included in the pushing base 203, the connecting plate 208 can be prompted to drive the cabinet structure 1 to slide horizontally through the moving block 207, so that the cabinet structure 1 is gradually moved away from the outside of the component mounting frame 204. The entire power distribution cabinet can be unfolded, so that the components inside the side panel 201 are exposed to the staff, thereby increasing the operating space for maintenance personnel, making the maintenance of components simpler and more convenient, reducing the difficulty of maintenance and the maintenance workload, thereby reducing the labor intensity of maintenance personnel and achieving the advantage of convenient maintenance.

[0031] Specifically, a ventilation port 103 is provided on the side of the cabinet panel 101 , and a ventilation fan 202 is provided on the side of the side panel 201 . The ventilation port 103 and the ventilation fan 202 are arranged opposite to each other.

[0032] In this embodiment, the ventilation port 103 and the ventilation fan 202 can form an air flow channel inside the power distribution cabinet, so that the heat generated by the components during operation can be taken away.

[0033] Specifically, a mounting opening is provided inside the mounting base plate 205 , and the driving device 206 is located inside the mounting opening.

[0034] In this embodiment, the drive device 206 can be inserted into or pulled out of the interior of the mounting base plate 205 by utilizing the mounting opening.

[0035] Specifically, a slide bar 213 is fixedly mounted on the inner wall of the driving box 209 , and a side end of the movable sleeve 212 is slidably connected to the surface of the slide bar 213 .

[0037] Specifically, a moving wheel is provided at the bottom end of the moving block 207, and the bottom end of the moving wheel contacts the ground or other platform.

[0038] In this embodiment, the moving wheels can slide along with the moving block 207 , thereby improving the movement stability of the moving block 207 .

[0039] During use, maintenance personnel can flip the cabinet door 102 to open the cabinet opening composed of the cabinet panel 101 and the side panel 201, so that the component mounting rack 204 is exposed. At this time, the staff can observe the working status of the components.

[0040] When it is necessary to carry out in-depth inspection of the components, the drive device 206 is started, so that the built-in power supply inside the drive box 209 drives the drive turntable 210 to rotate, causing the eccentric pile 211 at the top of the drive turntable 210 to perform a circular motion. Since the eccentric pile 211 is located inside the movable sleeve 212 and is slidingly connected to the inner wall of the movable sleeve 212, the relative position of the eccentric pile 211 and the movable sleeve 212 changes during the movement, causing the movable sleeve 212 to start to slide along the direction of the slide rod 213, causing the movable sleeve 212 to drive the connecting plate 208 through the push rod 214 to drive the cabinet panel 101 to slide horizontally, causing the cabinet panel 101 and the side panel 201 to gradually separate, and the entire distribution cabinet can be unfolded, so that the components inside the side panel 201 are exposed to the staff.

[0041] In summary, the power distribution cabinet for coal mines, which is easy to maintain, is provided with an unfolding structure 2. The driving device 206 contained in the pushing base 203 can cause the connecting plate 208 to drive the cabinet structure 1 to slide horizontally through the moving block 207, so that the cabinet structure 1 is gradually moved away from the outside of the component mounting frame 204. The power distribution cabinet as a whole can be unfolded, so that the components inside the side panel 201 are exposed to the staff, thereby increasing the operating space for maintenance personnel, making the maintenance of components simpler and more convenient, reducing the difficulty of maintenance and the maintenance workload, thereby reducing the labor intensity of maintenance personnel and achieving the advantage of convenient maintenance.

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
