Description

Technical Field

[0001] This invention relates to the field of power distribution cabinet technology, and more specifically, to an easy-to-maintain power distribution cabinet and its maintenance method. Background Technology

[0002] Currently, distribution boards are equipped with a large number of electrical components, instruments, switches, etc. However, when repairing the distribution cabinet, the distribution board is located inside the cabinet and needs to be removed from the bottom of the cabinet. After the repair is completed, the distribution board is then reinstalled at the bottom of the cabinet to accommodate all the electrical components, instruments, switches, etc. The process of removing the distribution board and repairing it is quite cumbersome. Existing multi-door structures offer limited convenience, as the left and right support columns at the front can obstruct the view and cause angular and directional interference during repairs. This presents a significant technical obstacle to the further development of fully automated robotic repair, necessitating a repair structure that can overcome these shortcomings.

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0015] The preferred embodiment of the present invention is an easy-to-maintain power distribution cabinet, such as... Figure 1 As shown, see also Figures 2-4The cabinet includes a bottom box 1, a top box 2, and a longitudinal connecting plate 3. The upper end of the connecting plate 3 is fixedly connected to the rear end of the top box 2, and the lower end of the connecting plate 3 is fixedly connected to the rear end of the bottom box 1. A left door 4 and a right door 5 are respectively provided on the two sides of the connecting plate 3 for lateral rotation. The cabinet also includes a left support column 6 and a right support column 7. The left support column 6 is connected to the left door 4 via a left connecting rod 8, and the right support column 7 is connected to the right door 5 via a right connecting rod 9. The lower end of the top box 2 has a first left slide rail 20 and a first right slide rail 21 that are slidably connected to the left support column. When the left support column 6 slides backward, it pushes the left door 4 to open via the left connecting rod 8. When the right support column 7 slides backward, it pushes the right door 5 to open via the right connecting rod 9. The upper end of the bottom box 1 has a second left slide rail 10 and a second right slide rail 11 that are slidably connected to the left support column. Both the left support column 6 and the right support column 7 are equipped with locking units to lock the position after sliding. Under normal use, both the left support column 6 and the right support column 7 are located at the foremost position of their sliding stroke and are locked by the locking unit. During maintenance, the locking units of the left support column 6 and the right support column 7 are unlocked, and then the left support column 6 and the right support column 7 are pushed backward. The left door and the right door are opened by the left connecting rod 8 and the right connecting rod 9, respectively. After they are opened to the correct positions, the left support column 6 and the right support column 7 are locked by the locking unit. The left connecting rod 8 and the right connecting rod 9 can use existing connecting rod structures. The improved structure of this application is easy to operate, eliminating the obstruction caused by the left and right support columns. It not only facilitates manual maintenance but also clears the way for subsequent automated maintenance of the robotic arm.

[0016] Preferably, the cabinet also includes a front door 22, which is mounted on the top cabinet 2 via an arc track 23. The top cabinet 2 is provided with a drive mechanism that drives the front door to rotate along the arc track. More preferably, the drive mechanism includes an electric push rod, the movable end of which is connected to the front door via a rubber column. This not only reduces cost but also provides shock absorption and lowers the precision requirements for assembly.

[0017] Preferably, the locking unit includes two parallel abutment rods 100, with racks 101 provided on opposite sides of each abutment rod 100. Each abutment rod 100 has a rubber pad at its end. A drive gear 102 is positioned between the two abutment rods 100, meshing with both racks 101. A drive rod 103 is coaxially fixed to the drive gear 102, and a damping sleeve 104 connected to the outside is fitted onto the drive rod 103. A rotating handle 105 is provided at the end of the drive rod 103. Both the left and right support columns include a tube body 106. The tube body 106 has openings at both ends. Two clamping rods 100 and a drive gear 102 are all located inside the tube body 106. The clamping rods are slidably connected to the inner wall of the tube body. The drive rod 103 passes through the tube body 106. The rotating handle 105 is located outside the tube body 106. The damping sleeve 104 is installed on the tube body 106. During adjustment, rotating the rotating handle 105 drives the drive gear 102 to rotate through the drive rod 103, thereby causing the two clamping rods 100 to extend or retract, achieving the purpose of locking and unlocking. The damping sleeve maintains the locked and unlocked state. Understandably, the combination of damping sleeve and rotary handle can also be replaced with a drive motor to achieve automated control, which is also possible, but the cost will be relatively higher.

[0018] Preferably, the damping sleeve 104 includes a connecting ring 1040 fixedly connected to the tube body 106. The connecting ring 1040 is sleeved on the drive rod 103, and a plurality of abutting friction plates 1041 are provided inside the connecting ring 1040. A screw 1042 is threaded through the connecting ring 1040, and the end of the screw 1042 is connected to the abutting friction plate 1041. The friction force of the abutting friction plate against the drive rod 103 is changed by adjusting the position of the screw, thereby adjusting the magnitude of the damping force. The overall structure is simple and low in cost. It is understood that the damping sleeve can also be replaced with other existing damping structures.

[0019] A maintenance method for an easy-to-maintain distribution cabinet, applied to the aforementioned easy-to-maintain distribution cabinet, is implemented as follows: Under normal use, both the left and right support columns are located at the foremost position of their sliding stroke and are locked by the locking unit. During maintenance, unlock the locking units of the left and right support columns, then push the left and right support columns backward to open the left and right doors via the left and right connecting rods respectively. Once opened, lock the positions of the left and right support columns using the locking units. The improved structure of this application is easy to operate, eliminating the obstruction caused by the left and right support columns. It not only facilitates manual maintenance but also clears the way for subsequent automated maintenance of the robotic arm.

[0020] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
