Problems solved by technology
[0003] At present, in order to shorten the construction period and improve construction efficiency, more and more prefabricated concrete foundations are used as the base of the metering box to fix the metering box. The bottom of the metering box is inserted into the groove on the concrete foundation. However, this structure often occurs If rainwater enters the groove and the bottom of the power distribution pair is soaked for a long time, the shell may be damaged and electric leakage may occur

Embodiment
[0017] Such as figure 1 , figure 2 As shown, this embodiment discloses a metering box with a waterproof mechanism. The sealant block on the corner is provided with a through hole in the middle part of the sealant block, and the piston rod of the cylinder is inserted into the through hole.
[0018] When in use, the pressure sensor is set on the side wall at a distance from the bottom plate, which can be adjusted according to the actual situation. There are two pressure sensors. When there is water in the groove, after the pressure sensor collects the pressure signal, the sensor controller, The controller controls the movement of the cylinders at the four corners, and the piston rod passes through the through hole to support the cabinet body to rise for a certain distance to avoid being soaked.

The invention discloses a metering box with a waterproof mechanism. The metering box comprises a cabinet body, wherein the waterproof mechanism is arranged in the cabinet body and comprises a pressure sensor arranged on the side wall and sealant blocks arranged at four corners of a bottom plate; a through hole is arranged in the middle part of each sealant block; and a piston rod of an air cylinder is inserted into each through hole. The metering box has the beneficial effects that the pressure sensor is arranged, at a distance from the bottom plate, on the side wall; when water exists in a groove, the pressure sensor collects a pressure signal, then a sensor controller controls the air cylinders at four corners to move, the piston rods penetrate outside from the corresponding through holes and the cabinet body is supported to ascend a distance, so that the cabinet body is prevented from being soaked.
Description
technical field [0001] The invention belongs to the technical field of metering box production, in particular to a metering box with a waterproof mechanism. Background technique [0002] The metering box is the final equipment of the power distribution system. It is the general name of the motor control center. The metering box is used in the occasions where the load is relatively scattered and the circuit is small. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearby load. . [0003] At present, in order to shorten the construction period and improve construction efficiency, more and more prefabricated concrete foundations are used as the base of the metering box to fix the metering box. The bottom of the metering box is inserted into the groove on the concrete foundation. However, this structure often occurs If rainwater enters the groove and soaks the bottom of the power distribution pair for a long time, ...
