DETAILED DESCRIPTION

[0013] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0014] Embodiment. An anti-dumping electrical control cabinet is constructed as follows Figure 1-3 As shown, it includes a cabinet 1, a shock-absorbing seat 2 is provided at the bottom of the cabinet 1, a hidden anti-dumping module 3 is provided at the front and rear ends of the bottom of the cabinet 1, and a rotating counterweight module 4 is provided at the top of the cabinet 1; an inclination sensor 5 is also provided in the middle of the upper and lower ends of the cabinet 1, and the inclination sensor 5 is connected to a controller 6, which is connected to the hidden anti-dumping module 3 and the rotating counterweight module 4.

[0015] The shock-absorbing seat 2 includes a base 201 fixed to the lower surface of the cabinet 1 , a rubber base 202 is provided below the base 201 , and a telescopic guide rod 203 and a spring 204 are provided between the rubber base 202 and the base 201 .

[0016] The front and rear sides of the bottom of the cabinet 1 are both provided with an open groove 7 for placing a hidden anti-dumping module 3; the hidden anti-dumping module 3 includes a first support plate 301 and a second support plate 302 located in the open groove 7, and the first support plate 301 and the second support plate 302 are rotatably connected to each other; a partition plate 11 is provided above the open groove 7, and a waist-shaped groove 8 is provided in the partition plate 11, and a sliding rod 303 located in the waist-shaped groove 8 is provided at the other end of the first support plate 301 and the second support plate 302; a double-headed cylinder 9 is provided in the middle part above the partition plate 11, and a connecting rod 10 is provided at the output end of the double-headed cylinder 9, and the end of the connecting rod 10 at the corresponding end is rotatably connected to the sliding rod 303.

[0017] The rotary counterweight module 4 includes a circular ring-shaped slide groove 401 located at the top of the cabinet 1, an arc-shaped counterweight block 402 is arranged in the circular ring-shaped slide groove 401, and the inner wall of the arc-shaped counterweight block 402 is provided with a toothed structure; a central driver 403 is provided in the middle position of the top of the cabinet 1, and a driving gear disc 404 is provided at the output end of the central driver 403, and the toothed surface of the driving gear disc 404 is meshed with the toothed structure.

[0018] A cavity is also provided above the partition to prevent double-headed cylinders.

[0019] The present application arranges inclination sensors at both ends of the cabinet body, thereby monitoring and comparing the inclination angles of the upper and lower ends of the cabinet body to ensure the accuracy of the judgment of the electrical control cabinet.

[0020] In actual use, the controller collects and analyzes the data from the inclination sensors at the upper and lower ends. When the set tipping condition is triggered (when either the inclination angle of the upper or lower inclination sensors is greater than the set inclination angle, or the difference in inclination angles detected by the inclination sensors at the upper and lower ends is greater than the set value), the hidden anti-tip module at the corresponding position begins to extend to prevent the cabinet from tipping over. At the same time, the rotating counterweight module controls the arc-shaped counterweight block to rotate in the opposite direction to the specified position to further prevent tipping.

[0021] The working process of the rotating counterweight module: the central driver (preferably a driving motor) starts working, driving the driving toothed disc (the outer cylindrical surface is a toothed surface) to rotate, and the toothed surface of the driving toothed disc cooperates with the toothed structure of the arc-shaped counterweight block, driving the arc-shaped counterweight block to move in the opposite direction of the tipping direction to reduce the risk of tipping. The rotating counterweight module of the present application can flexibly adjust the counterweight direction, and the adjustment direction is 360 degrees without dead angles.

[0022] The working process of the hidden anti-dumping module: the output end of the double-headed cylinder begins to contract, driving the connecting rod to move toward the double-headed cylinder, and then driving the other end sliding rods of the first support plate and the second support plate to move along the waist-shaped groove toward the double-headed cylinder (that is, move toward the center of the opening groove), and the rotating connecting ends of the first support plate and the second support plate move outward to form supporting feet, which support and prevent the cabinet from tipping over.
