[0023] As shown in Figure 1 Figure 2 A relay protection box convenient to overhaul, including box 4, box 4 outside is provided with shell 2, shell 2 bottom is connected on base 1, relay protection equipment is installed above base 1, shell 2 front is hinged with box door 3, shell 2 top movably is equipped with box cover 51;Box 4 includes control panel 41, back plate 42 and two side plates 43, control panel 41 upper portion is connected with back plate 42 upper portion, back plate 42 is connected with two side plates 43 as a whole. The control panel 41, the back plate 42 and the two side plates 43 of the box 4 are connected into a whole, and the whole is arranged in the shell 2.

[0024] As shown in Figure 3 Figure 4As shown, the back of the back plate 42 is provided with a tooth groove 61, which is engaged with a gear 62, the gear 62 is rotatably installed in a protective shell 64 through a rotating shaft 63, the protective shell 64 is connected to the upper part of the back plate of the shell 2, the outer end of the rotating shaft 63 is connected to the output end of the motor 65, and the motor 65 can drive the entire box body 4 to move up and down.

[0025] When overhauling, remove the box cover 51 at the top of the shell 2, start the motor 65, the motor 65 drives the gear 62 to rotate, the gear 62 drives the tooth groove 61 engaged with it to move upward, thereby driving the entire box body 4 to rise, so that the relay protection equipment installed in the shell 2 is exposed, facilitating the operation of overhauling.

[0026] As preferred, as shown in the drawings, Figure 2 Figure 3 As shown, the two side plates of the shell 2 are symmetrically provided with a limiting groove 71, and a short column 72 is connected in the limiting groove 71; the inner end of the short column 72 is connected to the two side plates 43 of the box body 4, and the outer end is connected with a fixed block 73. Under the cooperation of the limiting groove 71, the short column 72 and the fixed block 73, the lifting movement of the box body 4 can be limited and guided, so that the lifting movement is more stable.

[0027] As preferred, as shown in the drawings, Figure 4 As shown, the box cover 51 is movably arranged at the top of the shell 2, and the specific structure is that: the lower surface of the two sides of the box cover 51 is connected with a sliding block 52, the sliding block 52 is slidingly connected in a sliding groove 53, the sliding groove 53 is symmetrically arranged at the top of the shell 2, and the front of the sliding groove 53 is open and the back is closed; in this way, the box cover 51 can be slidingly installed or removed through the opening of the front of the sliding groove 53. Of course, the connection mode of the box cover 51 and the shell 2 is not limited to the above-mentioned sliding groove and sliding block connection, but also can be other connection modes which are beneficial to the opening or removal of the box cover 51, such as hinge connection with one side of the shell 2, or screw connection, etc.

[0028] Further, in order to prevent the box cover 51 from sliding off during use, the top surface of the box door 3 is arranged flush with the top surface of the box cover 51, so that after the box door 3 is closed during use, the upper part of the box door 3 can just abut against the opening of the front of the sliding groove 53, preventing the box cover 51 from sliding out of the sliding groove 53; when overhauling, opening the box door 3 can remove the restriction of the box door 3 on the opening of the sliding groove 53, so that the sliding blocks 52 at both ends of the box cover 51 can slide out of the opening end of the sliding groove 53 for disassembly.

[0029] As preferred, as shown in the drawings, Figure 2 Figure 5 As shown, the upper inner side of the back plate 42 is provided with a connecting rod 81, the other end of the connecting rod 81 is connected with a U-shaped block 82, the other end of the U-shaped block 82 is rotatably connected with the upper part of the control panel 41 through a hinge 83. In this way, the control panel 41 can be turned open during overhauling, further removing the restriction of the box body 4 on the relay protection equipment, and facilitating the operation of overhauling.

[0030] Further, in order to facilitate the flip operation of the control panel 41, as shown in Figure 1 A handle 10 is arranged on the control panel 41.

[0031] Further, in order to prevent the control panel 41 from colliding with the relay protection device when being flipped closed, as shown in Figure 2 A stabilizing column 91 is arranged on the inner side of the lower part of the back plate 42, a stabilizing spring 92 is arranged in the stabilizing column 91, the other end of the stabilizing spring 92 is connected with a stabilizing rod 93, the other end of the stabilizing rod 93 is connected with a first magnetic attraction piece 94, and a second magnetic attraction piece 95 corresponding to the first magnetic attraction piece 94 is arranged on the inner side of the lower part of the control panel 41. When the control panel 41 is flipped closed, the second magnetic attraction piece 95 will be attracted to the first magnetic attraction piece 94, and at the same time, under the buffering action of the stabilizing spring 92, the control panel 41 can be stably closed.

[0032] Working principle: when being overhauled, the box door 3 is opened, the sliding blocks 52 on both sides of the box cover 51 are slid out of the opening end of the sliding slot 53 for disassembly, the motor 65 is started, the motor 65 drives the gear 62 to rotate, the gear 62 drives the tooth groove 61 engaged therewith to move upward, under the cooperation of the two side limiting grooves 71, the short column 72 and the fixed block 73, the whole box body 4 stably rises, so that the relay protection device installed in the shell 2 is exposed. At this time, the control panel 41 is flipped open by pulling the handle 10, and the restriction of the box body 4 on the relay protection device is further released, so as to facilitate the overhauling operation.

[0033] After the overhauling is completed, the control panel 41 is flipped closed by pulling the handle 10, the motor 65 is reversely rotated, the gear 62 is reversely rotated, the gear 62 drives the tooth groove 61 to move downward, thereby driving the whole box body 4 to stably descend, and when the second magnetic attraction piece 95 at the bottom of the control panel 41 is attracted to the first magnetic attraction piece 94, the motor 65 is turned off. Subsequently, the sliding block 52 of the box cover 51 is slid into the opening end of the sliding slot 53, and then the box door 3 is closed, thereby completing the installation of the box body.

[0034] The utility model is described in detail through specific and preferred embodiments, but those skilled in the art should understand that the utility model is not limited to the above-mentioned embodiments, and any modification, equivalent replacement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
