DETAILED DESCRIPTION
[0016] Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.
[0017] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further. Example
[0018] like Figs. 1-3 As shown, the sealing detection structure is installed on the mover. The sealing detection structure includes: a U-shaped lifting bracket, four pairs of lifting hydraulic push rods, a pair of lifting support blocks, two pairs of horizontally opposite concave blocks, a pair of horizontal support plates, a pair of horizontal hydraulic push rods, a pair of lifting arc support blocks, a pair of semi-circular fitting blocks, two pairs of semi-circular ring fitting blocks, two pairs of semi-circular liquid bladders, an electrorheological fluid tank, an electrorheological fluid pump, a diversion pump, a current transmitter, a pressure valve, a trigger, a locker, and a spray detection assembly.
[0019] Specifically, the U-shaped lifting bracket is mounted on the mover; four pairs of lifting hydraulic push rods are mounted parallel to each other on the mover; a pair of lifting support blocks are mounted on the pushing ends of the four pairs of lifting hydraulic push rods; two pairs of horizontally opposite concave blocks are respectively mounted parallel to each other on a pair of lifting support blocks; a pair of horizontal support plates are respectively movably inserted into the inner sides of the two pairs of horizontally opposite concave blocks; a pair of horizontal hydraulic push rods are respectively mounted on a pair of lifting support blocks, and the pushing ends of the pair of horizontal hydraulic push rods are respectively connected to a pair of horizontal support plates; a pair of lifting arc support blocks are respectively mounted on a pair of horizontal support plates; and a pair of semi-circular support blocks... The circular assembly blocks are respectively installed on a pair of lifting arc support blocks, the two pairs of semi-circular ring assembly blocks are respectively installed on a pair of semi-circular assembly blocks, the two pairs of semi-circular liquid bladders are respectively inserted into the two pairs of semi-circular ring assembly blocks, the current-varying liquid tank is installed on the mover, the current-varying liquid pump is installed on the current-varying liquid tank, and the current-varying liquid pump is connected to the two pairs of semi-circular liquid bladders through a pipe, the current transmitter is installed on the diversion pump, the pressure valve is installed on the semi-circular assembly block, the trigger is installed on the pressure valve, the locker is installed on a pair of semi-circular assembly blocks, and the spray detection component is installed on the semi-circular assembly block;
[0020] It needs to be explained that in the above, first, through the cooperation of the back-shaped lifting support and the four pairs of lifting hydraulic push rods, a pair of lifting support blocks can be accurately adjusted to the height matched with the detection pipeline. The cooperation of the two pairs of horizontally opposite concave blocks with the pair of horizontal support plates, and the fine adjustment of the pair of horizontal hydraulic push rods, ensure that the pair of lifting circular arc support blocks and the half-circle sleeve blocks can closely fit on the outer wall of the pipeline, forming a preliminary sealed space. Then, the addition of the two pairs of half-circle ring sleeve blocks and the half-circle liquid bag further enhances the sealing effect. The electrorheological fluid pump extracts electrorheological fluid from the electrorheological fluid tank and injects it into the half-circle liquid bag through the pipeline. In the electrified state, the electrorheological fluid will quickly become solid, thereby filling the tiny gap between the half-circle sleeve block and the pipeline, forming a tight screw rotation space. At this time, through the monitoring of the pressure valve and the trigger, the pressure change inside the sealed space can be detected in real time, thereby judging whether there is gas leakage.
[0021] As shown in Figs. 1-3 , the spray detection assembly comprises two pairs of spray horizontal screw rod modules, a pair of spray circular arc pipes, a plurality of spray nozzles, a spray glue tank, a high-pressure pump, a shunt pipe, and a plurality of scanning cameras.
[0022] Specifically, the two pairs of spray horizontal screw rod modules are installed on the two pairs of half-circle ring sleeve blocks, the pair of spray circular arc pipes are respectively installed on the moving ends of the two pairs of spray horizontal screw rod modules, the plurality of spray nozzles are evenly installed on the pair of spray circular arc pipes, the spray glue tank is installed on the mover, the high-pressure pump is installed on the spray glue tank, the shunt pipe is installed on the spray glue tank, and the shunt pipe is connected to the pair of spray circular arc pipes through the pipeline, and the plurality of scanning cameras are installed on the pair of spray circular arc pipes.
[0023] It needs to be explained that in the above, in order to more intuitively locate the leakage point, the spray detection assembly plays a key role. The two pairs of spray horizontal screw rod modules drive the pair of spray circular arc pipes to move around the pipeline, and the plurality of spray nozzles evenly spray the glue. If the pipeline has a leak, the glue will form an expanding bubble at the leakage point, and at the same time the scanning camera will capture this change in real time and feed the information back to the control system through the shunt pipe. The discharge valve is also provided on the half-circle sleeve block to facilitate the quick discharge of the gas and glue in the sealed space after the detection is completed. The pressure sensor monitors the pressure change in the half-circle sleeve block in real time, providing additional basis for leakage judgment; and the addition of the positioner ensures the accurate positioning and navigation of the entire device in complex environments.

[0025] As a preferred scheme, further, a pair of the half-round sleeve blocks are respectively provided with discharge valves.
[0026] As a preferred scheme, further, a pair of the half-round sleeve blocks are respectively provided with pressure sensors.
[0027] As a preferred scheme, further, the mover is provided with a positioner.
[0028] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
