[0027] The lifting assembly 2 includes a column 201, and a screw 202 is provided in the column 201, a worm 203 is provided below the screw 202, and a turbine 204 is meshed on one side of the worm 203, and a motor 205 is installed on one side of the turbine 204, a lifting frame 206 is provided on one side of the column 201, and one end of the lifting frame 206 is connected to a first sleeve 301, a push rod 302 is installed in the first sleeve 301, and the output end of the push rod 302 is connected to a second sleeve 303, and one side of the end of the second sleeve 303 is connected to a sealing block 306, and the number of the sealing blocks 306 is two groups, and an air needle 307 is provided in one group of the sealing blocks 306, and one end of the air needle 307 is connected to an air pipe 308;

The number of detection heads 4 is multiple groups, which can monitor the water surface in all aspects.

[0030] Specifically, a through hole is opened on one side of the bottom end of the water tank 1, and a control valve is installed in the through hole. The cross section of the water tank 1 is a hollow rectangular structure without a top plate, and several groups of detection heads 4 are equidistantly distributed on the top of the water tank 1.

[0031] Through the above technical solution, the through hole can be opened by opening the control valve, and the detection water 101 can be released and replaced.

[0032] Specifically, a slide slot is provided on one side of the column 201 , the lifting frame 206 passes through the slide slot and extends to the outside thereof, the screw rod 202 rotates in the column 201 , and the worm 203 is located below the screw rod 202 and rotates inside the column 201 .

[0033] Through the above technical solution, the turbine 204 and the worm 203 can prevent reversal, so that after the lifting frame 206 is positioned, it will not move without driving force, thus ensuring stability to a certain extent.

[0034] Specifically, the output end of the motor 205 passes through the column 201 and extends into the interior thereof, and a motor compartment is disposed on the outer side of the motor 205 .

[0035] Through the above technical solution, the lifting frame 206 is a "7"-shaped structure, which will not be affected by the side wall of the water tank 1 when descending. The two groups of lifting frames 206 are driven by two groups of motors 205 respectively, so the horizontal positions of the two groups of sealing blocks 306 can be different, and the distance between them can be adjusted by the push rod 302. Together, they can enable pipes of different shapes to be inspected.

[0041] Through the above technical solution, a controller is arranged outside the device, and the controller is electrically connected to the electronic components in the device, and the push rod 302 can be a push rod device such as an electric push rod.

[0042] When in use, it is necessary to connect an external power supply, which provides electrical energy for the device so that the device can operate normally. First, the pipeline to be tested is placed between the two groups of sealing blocks 306, and the two groups of sealing blocks 306 are used to block the openings at both ends of the pipeline respectively. By starting the push rod 302, the positions of the two groups of sealing blocks 306 can be adjusted according to the length of the pipeline, and a suitable sealing point can be selected. Then, air can be blown into the air needle 307 through the air pipe 308 to allow the gas to enter the pipeline to be tested, and then the motor 205 is started, so that the motor 205 drives the turbine 204 to rotate, and the turbine 204 drives the worm 203 meshing with it to rotate, so that the worm 203 drives the screw 202 to rotate in the column 201, and the rotation of the screw 202 drives the lifting frame 206 to rise and fall, thereby driving the fixed pipeline to descend into the test water 101, and multiple groups of detection heads 4 detect the water surface to observe whether there are bubbles floating.

[0043] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit thereof, and the scope of the invention is defined by the appended claims and their equivalents.
