[0020] By adopting the above technical solution, the purpose of closing the heat dissipation holes is achieved by staggering the through holes of the blocking member and the heat dissipation holes of the shell, and multiple heat dissipation holes are synchronously blocked under a short sliding stroke of the blocking member, which is beneficial to improving the efficiency of blocking the heat dissipation holes.
[0021] Preferably, the stopper is fixed between two adjacent sliding rods.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. A water tank is arranged outside the shell of the high-voltage ring network cabinet, and connected to the blocking piece through a connector, so that the water tank can collect rainwater in rainy weather. As the weight of the water tank gradually increases, the connecting piece and the blocking piece are forced to move downward under the action of the gravity of the water tank, thereby blocking the heat dissipation holes, which is beneficial to prevent rainwater from entering the shell through the heat dissipation holes;
[0025] 2. Through the setting of the elastic member, on sunny days, the water in the water tank evaporates and the overall weight of the water tank decreases, so that under the elastic force of the elastic member, the water tank is reset upward and the blocking member is driven to open the heat dissipation hole, which is conducive to automatically restoring the heat dissipation hole function on sunny days;

[0030] The following is combined with Figure 1-2 This application is described in further detail.
[0031] The present application embodiment discloses a digital high-voltage ring main unit. Figure 1 and Figure 2 , comprising a ring main unit body and a shell 1, the ring main unit body is installed and fixed inside the shell 1, wherein a plurality of heat dissipation holes 11 are opened on the side wall of the shell 1, and the heat dissipation holes 11 are arranged in an array.
[0032] In this embodiment, a water tank 2 for collecting rainwater is installed on the top of the shell 1. The water storage range of the water tank 2 covers the top of the shell 1, and the upper end opening of the water tank 2 widens toward the surroundings. A connecting member is provided between the shell 1 and the water tank 2, and the connecting member includes four vertically fixed on the outer bottom wall of the water tank 2, and four sliding rods pass through the top of the shell 1. The sliding rods are disposed at the four inner corners of the shell 1 and slide against the inner wall of the shell 1, which is conducive to reducing the occupation of the internal space of the shell 1. In order to improve the sliding stability of the sliding rod, a limit member 4 is installed at the inner corner position of the shell 1. The limit member 4 is specifically an angle steel, and the limit member 4 limits the sliding rod at the inner corner position of the shell 1.
[0033] In this embodiment, the connecting member is connected with a stopper 3 for closing a plurality of heat dissipation holes 11. The stopper 3 is a plate-like structure. Specifically, the stopper 3 is fixed between two adjacent slide bars and attached to the inner wall of the housing 1. The stopper 3 is provided with a plurality of through holes 31. When the stopper 3 is in the initial state, the plurality of through holes 31 of the stopper 3 are aligned with the plurality of heat dissipation holes 11 on the side wall of the housing 1, and the housing 1 is kept unobstructed inside and outside. When the amount of water in the water tank 2 increases, the slide bar and the stopper 3 slide downward under the gravity of the water tank 2, and the stopper 3 blocks the heat dissipation holes 11. The purpose of closing the heat dissipation holes 11 is achieved by mutually misaligning the through holes 31 of the stopper 3 and the heat dissipation holes 11 of the housing 1, and synchronously blocking a plurality of heat dissipation holes 11 is achieved under a relatively short sliding stroke of the stopper 3, which is conducive to improving the blocking efficiency of the heat dissipation holes 11.
[0034] In this embodiment, the housing 1 is equipped with an elastic member 5. When the amount of water in the water tank 2 decreases, the elastic member 5 drives the connecting member and the blocking member 3 to move upward until the blocking member 3 returns to the initial state, and the blocking member 3 opens the heat dissipation hole 11. The elastic member 5 is specifically a spring, which is fixed at the inner bottom wall of the housing 1, and one end of the spring away from the inner bottom wall of the housing 1 is connected to the lower end of the slide rod. The elastic force direction of the elastic member 5 is opposite to the gravity direction of the water tank 2, and the elastic force direction of the elastic member 5 is consistent with the length direction of the slide rod, which is conducive to improving the stability of the lifting and lowering of the water tank 2.
[0035] The implementation principle of a digital high-voltage ring main unit in the embodiment of the present application is:
[0036] In a heavy rain environment, the water tank 2 collects rainwater, and the amount of water in the water tank 2 increases. The gravity of the water tank 2 is greater than the elastic force of the elastic member 5, and the slide rod and the baffle 3 slide downward under the gravity of the water tank 2. The through hole 31 of the baffle 3 and the heat dissipation hole 11 of the outer shell 1 are misaligned with each other, and the heat dissipation hole 11 is closed.
[0037] In a sunny environment, the amount of water in the water tank 2 gradually decreases, the gravity of the water tank 2 is less than the elastic force of the elastic member 5, the slide rod and the baffle 3 slide upward under the elastic force of the elastic member 5, the baffle 3 returns to its initial state, the baffle 3 opens the heat dissipation hole 11, and the housing 1 resumes the heat dissipation function.
[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
