Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The following detailed description is provided for the specific embodiments of the present invention.

As shown in fig. 1 to fig. 3, a structure diagram of a front pouring sealant waterproof control box provided by an embodiment of the present invention includes:

the device comprises an upper box 1 and a lower box 2, wherein the upper box 1 and the lower box 2 form a sealing body through a sealing assembly, a battery 13 and an actuator 14 are installed in the sealing body, and a meter cover 3 is installed on the upper box 1;
