The circuit breaker base A supports the circuit breaker mounting base B, the pole C is arranged on the upper part of the circuit breaker mounting base B, and the circuit breaker chassis D is arranged on the lower part of the circuit breaker mounting base B. The circuit breaker chassis D is unobstructed;

[0039] Open-air circuit breakers are directly related to whether the entire power transformation and distribution system can operate normally. Therefore, the circuit breaker mechanism needs to be regularly inspected and maintained. However, on rainy days, the circuit breaker cannot be inspected and maintained to avoid water ingress and short circuit. In southern my country, it rains all year round, which will delay the maintenance period. Failure to complete the maintenance work on time will lead to delays, which will bring challenges to timely power transmission. In serious cases, it will also have social impacts and affect customer load supply. For this reason, a device that can also inspect the circuit breaker mechanism on rainy days is needed.

[0041] The awning 100 is available in a variety of sizes, which can be selected according to actual usage. The awning 100 includes a flexible tarpaulin 110, a foldable frame 120 and a reinforcement 130. The tarpaulin 110 is fixed on the frame 120, and the tarpaulin 110 covers the upper surface of the frame 120. The frame 120 is a square frame. The frame 120 has a first direction and a second direction that are perpendicular to each other. The length of the frame 120 in the first direction is fixed, and the length of the frame 120 in the second direction is adjustable. The frame 120 can be folded along the second direction for easy storage and carrying. The reinforcement 130 is detachably arranged in the frame 120. The reinforcement 130 is parallel to the second direction of the frame 120. The length of the reinforcement 130 matches the maximum length that can be reached in the second direction of the frame 120. The reinforcement 130 is supported on the second direction of the frame 120 to lock the length of the frame 120 in the second direction.

[0042] The bracket 200 is detachably connected to the reinforcement member 130 .

[0043] The frame 120 is covered with a tarpaulin 110, and the reinforcement 130 is used to support the second direction of the frame 120 so that the frame 120 is fixed in a rectangular shape, thereby forming a rain shelter 100. The rain shelter 100 is supported by multiple brackets 200, so that the rain shelter 100 is fixed to the upper part of the circuit breaker case D, so that the rain shelter 100 can shelter the circuit breaker case D and the nearby work area from rain, so that the circuit breaker mechanism can be inspected and repaired even in rainy weather, without affecting the construction period and without delay. The circuit breaker mechanism maintenance work is completed within the planned time, power is supplied to customers in advance, negative social impact is avoided, and the problem of delay caused by work stoppage on rainy days during the circuit breaker mechanism maintenance work is solved; in addition, the bracket 200 and the reinforcement 130 can be freely disassembled and combined, the reinforcement 130 and the frame 120 can be freely disassembled and combined, the frame 120 can be folded along the second direction, and then the rain shelter 100 can be folded and stored, so that the maintenance rain shelter has the characteristics of being light, adjustable in size, taking up little space, being easy to carry, and easy to use.

It can be seen that when the frame 120 is stored, the two fixed plates 121 move inward relative to each other along the second direction, and the two folding plates 122 are folded. The folding direction is preferably toward the inside of the frame, so as to facilitate the storage or carrying of the awning 100.
