[0021] S2: The cover structure is removed from the air intake pipe, the cover is removed from the air charging and discharging pipes, the support rod structure drives and adjusts the metering box until the metering box rotates to the air charging and discharging pipes facing downward and close to the air intake pipe, the air pump sucks out the gas in the sealed chamber to form a negative pressure, and the negative pressure realizes the internal expansion elastic deformation of the inner elastic insulating bag, and finally realizes that the inner elastic insulating bag and the inner wall of the metering box are attached to each other, the air charging and discharging pipes are separated from the air intake pipe, and the cover is reinstalled on the air charging and discharging pipes;
[0022] S3: The inner elastic support ring is elastically deformed and gathered, and is sent from the port ring into the inner elastic insulating bag. The inner elastic support ring is elastically reset in the inner elastic insulating bag to form a ring shape, and abuts against the inner side wall of the inner elastic insulating bag, and the inner elastic insulating bag is pressed against the inner wall of the metering box, and the inner elastic support ring is supported and positioned in the metering box through each inner support rod structure, and each electric energy meter can be installed on the installation net;
[0023] S4: When measuring for a short time, the first method is to open the box cover structure to expose the opening hole to measure the in and out of the electric wire. The second method is to remove the wire fixing sealing structure from the threading hole slot, and then pass the electric wire in and out of the threading hole slot for measurement. When measuring for a long time, in order to achieve full insulation protection of the electric energy meter in the metering box, the two sealing seats are disassembled and separated, and each is filled with a layer of clay in the mud storage chamber, and each measuring electric conductor is pressed into the wire pressing hole, and the two sealing seats are docked, and the sealing seats are sealed and embedded in the threading hole slot and connected to each other by mounting bolts, thereby achieving full insulation sealing in the metering box;
[0024] S5: After use and when it needs to be moved, remove the electrical wires from the wire fixing sealing structure, and then drive and adjust the meter box with the support rod structure. The opening hole of the meter box faces downward and abuts against the upper surface of the base. At this time, the flange is embedded in the upper edge sleeve and sealed against the base through the first sealing gasket, thereby realizing fully insulated and closed storage of the meter box.
[0025] Compared with the prior art, the present invention has the following beneficial effects:
[0026] 1. The gas inside the metering box is sucked out through the gas charging and discharging joint structure to form a negative pressure, so that the inner elastic insulating bag is elastically expanded and fits with the inner wall of the metering box, thereby achieving full coverage insulation of the metering box. When the metering box or the inner elastic insulating bag of the sealed chamber is damaged, the inner elastic insulating bag will be separated from the state of being attached to the inner wall of the metering box. On the basis of achieving full insulation and closure, it can also facilitate the staff to detect the insulation status;
[0027] 2. Install the electric energy meter under the condition that the inner elastic insulating bag plays an insulating protection role, and avoid the situation that the meter box and the inner elastic insulating bag are damaged, which causes the inner elastic insulating bag to wrap the electric energy meter and affect its use. The inner elastic support ring and the inner support rod structure can position and support the inner elastic insulating bag, and facilitate the installation and fixation of each electric energy meter;
[0028] 3. The inflation and deflation assembly has two functions. The first function is to exhaust the sealed chamber through the inflation and deflation joint structure. The second function is to inflate the central air cushion and the telescopic air arm. After the fully insulated and closed storage is completed, the air pump inflates the central air cushion to inflate and extend the telescopic air arm and push the hole plug cover out of the extended perforation, thereby achieving safety protection in the water environment.
[0029] 4. The wire fixing sealing structure can achieve the sealing of the connection between the electric wire and the meter box, thereby ensuring the overall closed insulation effect of the meter box. BRIEF DESCRIPTION OF THE DRAWINGS
