Description

Technical Field

[0001] The utility model relates to the technical field of automobile engine water pumps, in particular to a leakage detection mechanism for an automobile engine water pump. Background Art

[0002] In the cylinder block of a car engine, there are multiple water channels for cooling water circulation, which are connected to the radiator (commonly known as the water tank) located at the front of the car through water pipes, forming a large water circulation system. A water pump is installed at the upper water outlet of the engine, which is driven by a fan belt to pump out the hot water in the water channel of the engine cylinder block and pump in the cold water.

[0003] After the automobile engine water pump housing cavity is produced, the cavity opening of the automobile engine water pump housing is generally sealed and placed in a water storage tank containing water. The air tightness of the cooling water pump housing is judged by whether there are bubbles in the water in the water storage tank.

[0024] See also Figure 1-5 , the utility model provides a technical solution:

[0025] The automobile engine water pump leak detection mechanism includes a base 1, a recovery water tank 2, a test box 3, and a permeable plate 5. A notch 4 is provided on one side of the top of the base 1, and the bottom of the notch 4 is matched with a permeable plate 5. The top of the permeable plate 5 is fixedly connected to the test box 3, and the other side of the top of the base 1 is fixedly connected to the recovery water tank 2. An inner cavity is provided inside the base 1, and a water delivery pipe 8 is provided at the inner cavity of the base 1. One end of the water delivery pipe 8 is connected to the bottom center of the recovery water tank 2, and the other end of the water delivery pipe 8 is connected to the center of one side of the permeable plate 5. A first inner cavity 301 and a second inner cavity 302 are respectively provided on both sides of the top of the test box 3. The first inner cavity 301 and the second inner cavity 302 are connected by an exchange port 303. A connecting pipe 304 is provided at the inner center of the second inner cavity 302. The first inner cavity 301 is connected to the first inner cavity 301, and the surface of the connecting pipe 304 is connected to the sealing ring 11 by a thread. The interior of the sealing ring 11 is provided with an extension plate 1101. The back of the extension plate 1101 contacts the front of the connecting pipe 304. The sealing ring 11 seals the water pump housing cavity of the automobile engine and the connecting pipe 304. It should be noted that the inner surface of the connecting pipe 304 is provided with a thread matching the pipe of the water pump housing cavity of the automobile engine, and the sealing ring 11 is sleeved on the outside of the connecting pipe 304 without affecting it. The extension plate 1101 inside the sealing ring 11 matches the cross-sectional area of ​​the connecting pipe 304. After the extension plate 1101 contacts the port of the connecting pipe 304, the sealing ring 11 will no longer rotate backward. In addition, after the sealing performance of the sealing ring 11 is reduced, a new sealing ring 11 can be replaced.

[0026] A support mechanism 12 is provided on the other side of the bottom of the second inner cavity 302, and the support mechanism 12 includes a steel plate 1201, a sponge block 1202, a sponge fixing block 1203, and a fixing binding belt 1204. The bottom of the steel plate 1201 is fixed on both sides of the bottom of the second inner cavity 302, and a sponge block 1202 is provided between the two steel plates 1201. Sponge fixing blocks 1203 are provided at the four top corners of the sponge block 1202, and the bottom of the sponge fixing block 1203 is adhered to the top of the steel plate 1201.

[0027] Specifically, the bottom of the automobile engine water pump housing cavity is located on the top of the sponge block 1202. After placement, the sponge block 1202 will be subjected to pressure, causing the middle part of the sponge block to be compressed downward, thereby starting a certain buffering effect.

[0028] Furthermore, water outlets 6 are provided on both sides of the test box 3 , and the water outlets 6 are connected to faucets.

[0029] Furthermore, a plurality of water leakage holes 7 are provided on the top of the water permeable plate 5 . When the faucet is turned on, water will flow into the interior of the water permeable plate 5 through the water leakage holes 7 .

[0030] Furthermore, the top of the water-permeable plate 5 is located below the top of the base 1, and the discharged water is collected at the gap 4 to prevent the water from flooding.

[0031] Furthermore, a fixed binding belt 1204 is provided on the top of the support mechanism 12. It should be noted that the fixed binding belt 1204 is an existing mature technology, which is mainly used to bind the surface of the automobile engine water pump housing cavity and fix the automobile engine water pump housing cavity.

[0032] Furthermore, a water pump 9 is provided on the surface of the water delivery pipe 8 , and a one-way valve 10 is provided on the surface of the water delivery pipe 8 and at the connection point of the recovery water tank 2 .

[0033] Specifically, when water is transported to the recovery water tank 2, the water is mainly powered by the water pump 9. In order to prevent the water inside the recovery water tank 2 from flowing back into the test box 3, a one-way valve 10 is provided at the water delivery pipe 8. The one-way valve 10 will prevent the water inside the recovery water tank 2 from flowing back into the test box 3.

[0034] Working principle: The utility model is a car engine water pump leak detection mechanism. When in use, the pipe at the car engine water pump housing cavity is connected to the connecting pipe 304, and then water is poured into the test box 3 to test the car engine water pump housing cavity. After the detection is completed, the faucets on both sides of the test box are opened to let water flow into the inside of the water-permeable plate 5. The water will enter the inside of the water-permeable plate 5 from the leak port 7, and then be transported to the recovery water tank 2 through the water delivery pipe 8 to recycle the test water, reflecting the concept of environmental protection in the prior art. After the water in the test box 3 is completely recovered, the car engine water pump housing cavity is naturally dried, or the worker wipes the car engine water pump housing cavity located inside the test box 3 with a clean cloth. After the surface of the car engine water pump housing cavity is dry, the car engine water pump housing cavity can be taken out of the test box 3. Because the surface of the car engine water pump housing cavity is dry, no water will drip onto the ground, preventing the slippery ground from causing the tester to fall and thus damaging the car engine water pump housing cavity.

[0035] It is worth noting that the entire device is controlled by a controller. Since the controller is a commonly used device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
