[0002] During the use of the car, the water transmitted by the water pump is needed to absorb the heat generated by the engine, thereby cooling the engine.

[0003] After working for a long time, the automobile water pump will leak due to a lot of internal wear.

[0029] Refer to the attached Figure 1-Figure 7 According to an embodiment of the present invention, a housing leakage detection device for an automobile water pump production process includes a left fixing frame 11, an air intake box 17 is fixedly provided on the upper end surface of the left fixing frame 11, a right closing frame 15 is fixedly provided on the right end surface of the left fixing frame 11, a right detection box 2 is fixedly provided on the upper end surface of the right closing frame 15, a left supporting frame 3 is fixedly provided on the right end surface of the air intake box 17, an upper detection box 13 is fixedly provided between the right side of the upper end surface of the left supporting frame 3 and the left side of the upper end surface of the right detection box 2, and eight supporting frames 16 are fixedly provided on the lower end surface of the left fixing frame 11;

[0030] like Figure 4As shown, the left support frame 3 and the right detection box 2 are closed to form a detection inner cavity 25, and a detection frame 27 is fixed in the detection inner cavity 25, and a detection water pump 26 is fixed on the right side of the left support frame 3. An air intake pump cavity 22 is provided in the air intake box 17, and an air intake pump 23 is rotatably provided in the air intake pump cavity 22. The upper wall of the air intake pump cavity 22 is provided with an air inlet 18 connected to the outside world, and the right wall of the air intake pump cavity 22 is connected to the air intake cavity 21.

[0031] like Figure 4 As shown, the inner wall of the air leakage detection chamber 37 of the present invention is provided with evenly arranged detection rotating chambers 28, and a rotation detector 1 is fixedly provided in the detection rotating chamber 28. The rotation detector 1 is provided with a detection fan 29 on the end face of one side close to the detection water pump 26, and the rotation detector 1 can detect whether the detection fan 29 is rotating. The lower side of the right end face of the left support frame 3 is symmetrical and fixed with two pump body support frames 38. The right end face of the left support frame 3 is fixed with a support electromagnet 4, and the support electromagnet 4 is magnetic. The right end face of the support electromagnet 4 is connected to the left end face of the detection water pump 26 by magnetic force.

[0032] An upper sealed cavity 36 is provided in the upper detection box 13 , a water pump outlet 14 is fixedly provided on the upper end surface of the detection water pump 26 , an air outlet cavity 35 is provided in the water pump outlet 14 , and a sealing fixing plate 40 that can move up and down is provided in the upper sealed cavity 36 .

[0033] like Figure 6 As shown, an elastic sealing block 10 is fixedly provided on the lower end surface of the sealing fixing plate 40. The elastic sealing block 10 is made of elastic material and can play a sealing role. The left and right end surfaces of the sealing fixing plate 40 are provided with sealing connecting blocks 6. Two lower fixing blocks 5 are symmetrically and fixedly provided in the upper sealing cavity 36.

[0034] Specifically, the upper wall of the upper sealed chamber 36 is provided with an upper exhaust port 19 that communicates vertically. Two symmetrical, rotatable sealing rods 8 are disposed within the upper sealed chamber 36. The outer circumference of one sealing rod 8 is threadedly connected to a corresponding sealing communication block 6. This sealing rod 8 is connected to a sealing motor 9 to drive its rotation. The outer circumference of the other sealing rod 8 is slidably engaged with the corresponding sealing communication block 6. When the sealing motor 9 is activated, it rotates the sealing rods 8, thereby driving the sealing communication block 6 to move up and down, and further driving the sealing fixing plate 40 to move up and down.

[0035] like Figure 6 As shown, a flow rate detector 24 is fixedly provided on the upper wall of the air inlet cavity 21 and in the sealing fixing plate 40. The flow rate detector 24 can detect the gas flow in the area. A control panel 39 is fixedly provided on the right end face of the right detection box 2. The control panel can control the start and stop of all motors and magnets of the present invention.

[0036] like Figure 4 As shown, a transmission pipe 30 is fixedly provided on the upper side of the right end surface of the detection frame 27, and a signal processor 12 is fixedly provided on the upper end surface of the transmission pipe 30. The signal processor can receive and process the signal generated by the rotation detector.

[0037] A right electromagnet 34 is fixedly provided on the right side of the upper end surface of the left fixing frame 11, and a left electromagnet 33 is fixedly provided on the left side of the lower end surface of the right closing frame 15. The left fixing frame 11 and the right closing frame 15 are connected by the magnetic force of the right electromagnet 34 and the left electromagnet 33. The left electromagnet 33 and the right electromagnet 34 are magnetic when energized. A connecting electromagnet 7 is fixedly connected between the lower end surface of the upper detection box 13 and the left support frame 3 and the right detection box 2. The connecting electromagnet 7 is magnetic when energized.

[0038] The right wall of the air leakage detection cavity 37 is connected to a limiting cavity 31 . A limiting head 32 is fixedly provided on the right end surface of the detection water pump 26 . The right end surface of the limiting head 32 extends into the limiting cavity 31 .

[0039] The workflow of the present invention is as follows:

[0040] Before work, after the left electromagnet 33 and the right electromagnet 34 are powered off, the right closed frame 15 and the rotation detector 1 are removed. At this time, the detection inner cavity 25 is exposed to the outside world. Then the detection water pump 26 is placed on the upper end faces of the pump body support frames 38 on both sides, so that the water pump inlet 20 enters the air inlet cavity 21, and the water pump outlet 14 is directly above. The support electromagnet 4 is energized to allow the detection water pump 26 to complete the positioning work. Then the right closed frame 15 and the right detection box 2 are moved to the left, and the left electromagnet 33 and the right electromagnet 34 are energized to seal the left support frame 3 and the right detection box 2. The left fixing frame 11 and the right closed frame 15 are connected to each other by magnetic force. At this time, the limit head 32 enters the limit cavity 31.

[0041] After the installation is completed, the upper detection box 13 is placed on the upper end surface of the connecting electromagnet 7, and the upper detection box 13 is fixed to the upper end surfaces of the left support frame 3 and the right detection box 2 by relying on the magnetic force of the connecting electromagnet 7. At this time, the sealing motor 9 is started, and the sealing motor 9 starts to drive the sealing rotating rod 8 to rotate, thereby driving the sealing connecting block 6 to move downward, and then driving the sealing fixing plate 40 to move downward until the air outlet pipe cavity 35 is sealed by the elastic sealing block 10. At this time, the air intake pump 23 is started, and the air intake pump 23 starts to rotate, so that the external gas enters the detection water pump 26 through the air intake pump cavity 22, the air intake cavity 21 and the water pump inlet 20, and is transmitted to the air outlet pipe cavity 35. The flow rate detectors 24 at two places detect the air pressure and gas flow rate differences in the area.

[0042] At the same time, after the gas enters the detection water pump 26, if leakage occurs on the surface of the detection water pump 26, the transmitted gas will be blown to the surface of the detection fan 29 through these gaps, thereby driving the detection fan 29 on the same side to start rotating, and the rotation signal is detected by the rotation detector 1 and sent to the signal processor 12 through the transmission pipe 30. The signal processor 12 determines the position of the rotating fan and sends a signal to the control panel 39.

[0043] After the detection is completed, the disassembly work can be completed by disconnecting the activation of the left electromagnet 33 and the right electromagnet 34 so that the magnetic force between the left electromagnet 33, the right electromagnet 34 and the connecting electromagnet 7 disappears, thereby taking out the detection water pump 26.
