[0045] Embodiment 1

[0047] The leakage detection assembly comprises a driving part 9, a centrifugal pump 6, a container 7, a heating element 11 and a water receiving element 8, wherein:

[0048] The driving part 9 is fixed to the supporting part 1;

[0049] The centrifugal pump 6 is fixed to the support part 1 and driven by the driving part 9, and the output end of the centrifugal pump 6 is connected to the water inlet pipe of the water tank;

[0050] The container 7 is fixed to the support portion 1 and connected to the water outlet pipe of the water tank;

[0051] The heating element 11 is used to heat the liquid in the pipeline and is respectively connected to the input end of the centrifugal pump 6 and the container 7 pipeline;

[0052] The water receiving part 8 is fixed to the supporting part 1 and is located directly below the water tank. The interior of the water receiving part 8 is sloped, and a drainage hole 14 is provided at one end of the lower part. The drainage hole 14 is connected to the external waste liquid tank pipeline.

[0053] The pressure control assembly includes a tee 22, a temporary storage box 5, and a pressure cover 23, wherein:

[0054] The tee 22 includes a first outlet, a second outlet, and a third outlet;

[0055] The temporary storage box 5 is fixed to the upper end of the support part 1 and connected to the second outlet pipe;

[0056] The pressure cover 23 is threadedly matched with the third outlet. The lower end of the pressure cover 23 is provided with a second chamber 32. The upper end of the second chamber 32 is fixed with a second spring 12. The other end of the second spring 12 is fixed with a sealing portion 33. The sealing portion 33 is slidably matched with the inner wall of the second chamber 32. The sealing portion 33 extends to the inner port of the first outlet and seals the first outlet.

[0057] In this embodiment, the driving unit 9 is a motor;

[0058] In this embodiment, the cooling unit 26 is composed of a copper tube and a heat sink;

[0059] In this embodiment, the second spring 12 is a compression spring;

[0060] In this embodiment, when the water tank needs to be tested for water leakage, it is fixed on the support part 1, and the outlet of the centrifugal pump 6 is connected to the water inlet pipe of the water tank, and the container 7 is connected to the water outlet pipe of the water tank. At the same time, the first outlet of the tee 22 is fastened to the upper end of the water tank and penetrates the inside of the water tank, and the pressure cover 23 is tightened so that the sealing part 33 seals the first outlet under the action of the second spring 12. At this time, the driving part 9 is turned on to drive the centrifugal pump 6 to start working. Under the action of the centrifugal pump 6, the coolant in the container 7 is heated by the heating element 11, enters the water tank through the water inlet pipe, and returns to the container 7 through the water outlet pipe to form a loop. During the flow of the coolant, observe the water accumulation in the water receiving part 8. If there is water accumulation, it means that the water tank is leaking. If there is no water accumulation, it means that the water tank is well sealed.

[0061] The sloped arrangement of the water receiving member 8 allows the accumulated water to be automatically discharged;

[0062] During the detection process, the temperature of the coolant continues to rise until it reaches its boiling point and turns into gas. As the gas increases, the pressure in the water tank continues to increase until the sealing part 33 is lifted up, so that the sealing part 33 is separated from the first outlet. At this time, the gas generated can enter the interior of the temporary storage box 5 through the second outlet, realizing the pressure relief function. At the same time, it realizes the detection of water tank leakage under different pressures, which is closer to its actual working conditions and ensures the performance of the water tank.

[0063] The water tank leakage detection process can be controlled by the system in conjunction with sensors, accurately grasping the nodes for starting and stopping detection, and stopping at any time when leakage occurs during the detection process, thereby achieving the purpose of intelligent control.

[0064] Embodiment 2

[0065] refer to Figure 3 , Figure 5 and Figure 6 This embodiment is basically the same as the first embodiment, and the following structure is added on the basis of the first embodiment: the leakage detection component further includes a cleaning component, the cleaning component includes a first pulley 10, a rotating shaft 17, a stirring part 19, a brush part 21 and a filtering part 29, wherein:

[0066] The first pulley 10 is fixedly arranged at the output end of the driving part 9;

[0067] The rotating shaft 17 is connected to the container 7 by a bearing, and a second pulley 13 is fixed to the rear end of the rotating shaft 17, and the second pulley 13 is connected to the first pulley 10 by a belt;

[0068] The stirring part 19 is fixedly mounted at the front end of the rotating shaft 17 and is provided in multiple groups;

[0069] The brush portion 21 is disposed at the end of the stirring portion 19;

[0070] The filter unit 29 is disposed at the left pipe outlet of the container 7;

[0071] The leakage detection assembly further includes a dirt storage assembly, which includes a dirt storage member 16, a scraper portion 18 and a window 27, wherein:

[0072] The window 27 is arranged on the right side of the container 7;

[0073] The dirt storage member 16 is provided with a receiving chamber, which is fixed and sealed to the container 7. The receiving chamber extends into the container 7 through a window 27. The left outer wall of the receiving chamber is arc-shaped and does not contact the brush portion 21.

[0074] The scraper portion 18 is located at the upper left end of the accommodating chamber and is used to clean the brush portion 21;

[0075] In this embodiment, the brush portion 21 is made of a flexible material;

[0076] In this embodiment, since a lot of dirt and metal scraps are generated in the water tank during the production process and are present in various parts of the water tank, during the detection process, the dirt in the water tank can be washed into the container 7 through the circulation of the coolant, thereby achieving the purpose of cleaning the water tank;

[0077] Driven by the driving part 9, the first pulley 10 starts to rotate clockwise, and drives the second pulley 13 to rotate clockwise through the belt, thereby driving the stirring part 19 to start rotating. During the rotation of the stirring part 19, the coolant in the container 7 is continuously stirred, so that the dirt is not easy to settle, and part of it adheres to the brush part 21. During the rotation of the brush part 21, it will contact the scraping part 18, so that the dirt adhered to the brush part 21 is cleaned and falls into the accommodating chamber of the dirt storage part 16, so as to achieve the purpose of separating the dirt from the coolant and ensure the cleanliness of the coolant.

[0078] The dirt storage part 16 is cleaned every once in a while to prevent it from being filled up;

[0079] During the rotation of the brush portion 21 , the brush portion 21 will contact the filter portion 29 . During the vibration of the filter portion, dirt on the filter portion will be shaken off or adhered to the brush portion 21 , thereby ensuring that the filter portion 29 is unobstructed.

[0080] Embodiment 3

[0081] refer to Figure 7 This embodiment is basically the same as the second embodiment, and the following structure is added on the basis of the second embodiment: the leakage detection component also includes a switching component, the switching component includes a first chamber 30, a first spring 31, a pressure-bearing part 20 and a rotating component, wherein:

[0082] The first chamber 30 is disposed in the middle of the left side of the stirring portion 19, the first spring 31 is fixedly disposed at the bottom of the first chamber 30, the other end of the first spring 31 is fixed to the pressure-bearing portion 20, and the pressure-bearing portion 20 and the first chamber 30 are slidably matched;

[0083] The first chamber 30 and the second chamber 32 are both provided with hydraulic oil inside and are connected by a rotating assembly;

[0084] The rotating assembly comprises a rotating chamber 34 and a fixed chamber 35, wherein:

[0085] The rotating chamber 34 is connected to the first chamber 30, the fixed chamber 35 is connected to the second chamber 32, and the rotating chamber 34 and the fixed chamber 35 are connected by bearings;

[0086] In this embodiment, the second spring 12 is a tension spring;

[0087] In this embodiment, since the water tank is configured on different vehicles, and different car owners have different requirements for coolant, some car owners may choose water as coolant for economical reasons, while some car owners may choose emulsion as coolant for higher quality, and water and emulsion have different performances;

[0088] In practice, the boiling point of emulsion is slightly higher than that of water, and the viscosity is slightly stronger. When the engine of the same type is cooled, the pressure relief temperature should be kept consistent, so that the cooling efficiency can be maximized. Therefore, the pressure relief pressure of the two coolants is different. This leakage detection device can adjust the pressure relief pressure according to the two different coolants.

[0089] Specifically, in this embodiment, the pressure cover 23 is tightened so that the sealing portion 33 seals the first outlet under the action of the second spring 12 and the hydraulic oil in the second chamber 32. The second spring 12 has a relatively small force, ensuring that when the hydraulic pressure in the second chamber 32 is the minimum, the hydraulic pressure is also greater than the restoring force of the second spring 12.

[0090] In the initial state, the pressure-bearing part 20 is in a free state. At this time, the liquid pressure in the second chamber 32 is the largest. When the stirring part 19 starts to rotate clockwise, the inner side of the pressure-bearing part 20 is affected by the pressure of the coolant and starts to move away from the surface of the stirring part 19, so that the volume of the first chamber 30 increases and the pressure decreases. The hydraulic oil in the second chamber 32 enters the first chamber 30. As the hydraulic oil in the second chamber 32 decreases, the pressure on the sealing part 33 decreases, so that the pressure of the sealing first outlet decreases.

[0091] When the coolant is water, the pressure-bearing part 20 is subjected to less force because the viscosity of water is smaller. When the coolant is an emulsion, the pressure-bearing part 20 is subjected to greater force because the viscosity of the emulsion is larger. Therefore, when the coolant is water, the sealing pressure of the sealing part 33 on the first outlet is greater. The boiling point of water is lower than that of the emulsion. Under higher pressure, it can reach the same temperature as the emulsion before vaporizing, thereby ensuring the consistency of the pressure relief temperature when using different coolants, and detecting the leakage of the water tank under different pressures when using different coolants, which is more in line with the actual use of the water tank.

[0092] A cover plug 15 is threadedly connected to the upper side of the container 7 to facilitate the addition and replacement of the coolant in the container 7 .
