[0002] A floor washer is a cleaning machine suitable for cleaning hard floors while sucking up sewage and taking the sewage away from the site. It is widely used in places with broad hard floors such as stations, docks, airports, workshops, warehouses, schools, hospitals, restaurants, shopping malls, etc. The concept of cleaning with machines instead of manpower has taken root in people's hearts. The sewage tank is an important component of the floor washer. It is small in volume and is generally installed at the position of the charging base of the floor washer for storing sewage. During the production and processing of the sewage tank, in order to ensure the quality of the sewage tank, it is necessary to conduct airtightness detection on the sewage tank. During the test process, the detector will apply a certain pressure to the inside of the water tank and monitor the pressure change inside the water tank in real time.

A probe mechanism 4 is fixedly connected to the top of the workbench main body 101 corresponding to the position of the water level gauge. The overall device is set and adjusted through the chassis device 5. During use, the sewage tank main body 7 is placed in the card slot 104 on the four positioning blocks 103 to position the sewage tank main body 7. The operator controls the fixing mechanism 2 to operate downward to press the sewage tank main body 7 tightly inside the card slot 104 to fix the sewage tank main body 7. The detection mechanism 3 operates to block the water outlet of the sewage tank main body 7 and fill the inside of the sewage tank main body 7 with gas, and continuously detects the change of the air pressure inside the sewage tank main body 7. The probe mechanism 4 operates to closely adhere to the wiring metal of the water level gauge of the sewage tank main body 7 and energize to detect whether the circuit of the water level gauge is intact, and the detection result is displayed through the display mechanism 6. After the detection is completed, the fixing mechanism 2, the detection mechanism 3 and the probe mechanism 4 reset to release the sewage tank main body 7.

[0026] The fixing mechanism 2 is located at the axis position of the sewage tank main body 7 to ensure uniform force on the sewage tank main body 7. The positioning blocks 103 are located at the four corners of the sewage tank main body 7, and the four corners of the sewage tank main body 7 are placed inside the clamping grooves 104 to position the sewage tank main body 7.

When the telescopic column 202 moves up and down, the roller 205 slides along the guiding groove 206, so that the telescopic column 202 rotates by 90 degrees while moving up and down. That is, when the telescopic column 202 moves downward, the telescopic column 202 rotates and the pressing block 204 moves above the sewage tank main body 7 to tightly press the sewage tank main body 7. When the telescopic column 202 moves upward, the telescopic column 202 rotates 90 degrees and moves away from above the sewage tank main body 7 and remains horizontal with the side surface of the sewage tank main body 7, which is convenient for taking the sewage tank main body 7.

The top end of the mounting frame 401 is fixedly connected to a third pneumatic telescopic rod 402. The bottom end of the third pneumatic telescopic rod 402 is fixedly connected to a probe main body 403. The third pneumatic telescopic rod 402 forms an angle of sixty degrees with the horizontal plane. When the sewage tank main body 7 is being detected, the third pneumatic telescopic rod 402 pushes the probe main body 403 downward, so that the test end of the probe main body 403 contacts the conductive metal of the water level gauge on the side surface of the sewage tank main body 7, and the circuit is energized to test whether it is unobstructed. After the detection is completed, the third pneumatic telescopic rod 402 drives the probe main body 403 upward to separate the probe main body 403 from the sewage tank main body 7.

[0032] Working principle of the utility model: Place the sewage tank main body 7 in the clamping groove 104 on the four positioning blocks 103. The operator controls the operation of the device through the control button 102. The first pneumatic telescopic rod 201 starts to drive the telescopic column 202 to move downward. At this time, the roller 205 slides along the guide groove 206 to make the telescopic column 202 drive the mounting rod 203 to rotate by 90 degrees, so that the pressing block 204 moves to directly above the sewage tank main body 7. At the same time, the pressing block 204 closely adheres to the top of the sewage tank main body 7 to press the sewage tank main body 7 tightly inside the clamping groove 104. The second pneumatic telescopic rod 301 pushes the blocking block 303 to block the water outlet of the sewage tank main body 7. At this time, the air outlet hole on the side of the blocking block 303 and the pressure detection device extend into the sewage tank main body 7. The inflation device operates to fill the sewage tank main body 7 with gas through the air duct 304. The pressure detection device detects the change of the internal pressure of the sewage tank main body 7 in real time. At the same time, the third pneumatic telescopic rod 402 pushes the probe main body 403 downward, so that the test end of the probe main body 403 contacts the conductive metal of the water level gauge on the side of the sewage tank main body 7 and powers on to test whether the circuit is unobstructed. The support frame 601 displays the detection results, that is, the change of the internal pressure of the sewage tank main body 7 and whether the water level gauge circuit is intact. When the sewage tank main body 7 meets the usage requirements, the indicator light 603 emits green light. When the sewage tank main body 7 does not meet the usage requirements, the indicator light 603 emits red light. After the detection is completed, the third pneumatic telescopic rod 402 drives the probe main body 403 upward to separate the probe main body 403 from the sewage tank main body 7. The second pneumatic telescopic rod 301 drives the blocking block 303 to move to separate the blocking block 303 from the sewage tank main body 7. The first pneumatic telescopic rod 201 pushes the telescopic column 202 upward. At the same time, the telescopic column 202 rotates by 90 degrees and moves away from above the sewage tank main body 7 to be horizontal with the side of the sewage tank main body 7, and then remove the sewage tank main body 7 after the detection is completed.
