Description

Technical Field

[0001] This utility model relates to an integrated water tank with leakage detection function, and in particular to an integrated water tank with leakage detection function applied in the field of water tanks. Background Technology

[0002] Integrated water tanks have wide applications in many fields, such as building water supply systems, industrial cooling circulation systems, and thermal management systems for new energy vehicles. They integrate multiple functions, providing the necessary water storage and distribution capabilities for the stable operation of the system.

[0003] Sealing is a crucial performance characteristic of water tanks. To ensure its sealing, a sealing test is required before use. For example, the specification of patent publication number CN210571249U discloses a secondary water tank leakage detection device. This device includes a frame, an airtightness testing component, and a metal probe pressing mechanism. The metal probe pressing mechanism includes a base plate and a clamping plate mounted on the base plate for placing the secondary water tank. A pressing cylinder is mounted on the side of the clamping plate. The pressing cylinder is connected to a pull-back cylinder positioned above the secondary water tank via a connecting plate. Movement of the pressing cylinder causes the pull-back cylinder to reciprocate along the secondary water tank. Negative pressure and positive pressure leakage tests of the secondary water tank are performed simultaneously without increasing the cycle time.

[0004] However, existing integrated water tanks lack effective leak detection capabilities. If a leak occurs during use and cannot be detected and addressed in a timely manner, it can lead to a series of adverse consequences. Therefore, an integrated water tank with leak detection capabilities is proposed to improve these issues. Utility Model Content

[0005] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that existing integrated water tanks lack effective leakage detection functions. If a leak occurs during the use of the water tank and cannot be detected and dealt with in a timely manner, it will lead to a series of adverse consequences.

[0006] To address the aforementioned problems, this utility model provides an integrated water tank with leakage detection function, comprising a tank body with an inlet pipe and an outlet pipe installed on its side:

[0007] Both the inlet and outlet pipes are fitted with a protective tube, which is connected to the water tank body. A water-stopping expansion rubber is fixed on the inner wall of the protective tube.

[0008] A water stop valve is installed on the water inlet pipe, and a valve handle is rotatably installed on the water stop valve. A trigger tube is fixedly connected to the first protective pipe. An expansion block that contacts the water stop expansion rubber is set inside the side of the trigger tube near the first protective pipe. The ends of multiple trigger tubes away from the first protective pipe are fixedly connected to an actuating tube. A push rod is slidably sealed at the end of the actuating tube away from the trigger tube. A tension spring is fixed between the push rod and the actuating tube.

[0009] The inside of the trigger tube and the actuation tube is filled with compressed gas. When the push rod slides outward, it pushes the valve handle to rotate toward the side where the stop valve is closed.

[0010] In the aforementioned integrated water tank with leak detection function, once a leak occurs at the connection of the inlet or outlet pipe, the water-absorbing and expanding properties of the water-stopping expansion rubber can be used to temporarily seal the leak. Additionally, the water-absorbing and expanding properties of the expansion block cause the push rod to slide outward, pushing the valve handle to rotate toward the side where the water-stop valve is closed, thus effectively preventing further water intake and reducing the risk of continuous leakage.

[0011] As a further improvement of this application, a second protective tube is sleeved on the outside of the first protective tube. The side end of the second protective tube is threaded through a fixing knob that abuts against the first protective tube. The first protective tube abuts against the outer wall of the water tank body. After the water-stopping expansion rubber expands, the first protective tube is fixed relative to the inlet or outlet pipe. At this time, the fixing knob can be loosened, and the first protective tube can be removed and replaced along with the inlet or outlet pipe.

[0012] As a further improvement of this application, the water-stopping expansion rubber does not come into contact with the inlet and outlet pipes, thus avoiding obstruction of the normal installation of the protective pipe, the inlet or outlet pipe. A water-absorbing sponge is fixed on the water-stopping expansion rubber to contact the inlet and outlet pipes. The water-absorbing sponge can ensure that when water seepage occurs, the water-stopping expansion rubber can come into contact with the seepage water in time and thus expand.

[0013] As a further improvement of this application, a water-enclosing trough is fixed to the lower periphery of the water tank body, and a water collection tank connected to the water-enclosing trough is installed at the bottom of the water tank body. Water that leaks out accidentally falls into the water-enclosing trough and flows into the water collection tank for collection.

[0014] As a further improvement of this application, a return water pipe is fixedly connected between the top of the water collection tank and the top of the water tank body. A water pump connected to the return water pipe is installed inside the water collection tank. The water pump, in conjunction with the return water pipe, pumps the water collected in the water collection tank back into the water tank body.

[0015] As a further improvement of this application, splash guards are fixedly fitted onto both the inlet and outlet pipes. The splash guards are located on the side of the protective pipe away from the water tank body. When splashing occurs at the inlet or outlet pipe, the splash guards can effectively prevent water from splashing to the surroundings, thereby protecting the surrounding objects.

[0016] As a further improvement of this application, the trigger tube is a transparent tube, and a color-changing silicone is connected to the end of the expansion block away from the protective tube. The color-changing silicone changes color when it comes into contact with water, and personnel can observe the specific location of water seepage from the outside of the trigger tube.

[0017] In summary, if a leak occurs at the connection between the inlet or outlet pipe, the water-sealing expansion rubber expands upon contact with water, temporarily sealing the leak. Simultaneously, the expansion block absorbs water and expands, increasing the air pressure in the trigger and actuation pipes. This causes the push rod to slide outwards, pushing the valve handle towards the side where the stop valve is closed, effectively preventing further water intake and reducing the risk of continuous leakage. Furthermore, any water that leaks accidentally falls into the containment trough and flows into the collection tank. A water pump, in conjunction with a return pipe, pumps the collected water back into the main water tank, preventing water waste. Attached Figure Description

[0025] The following describes one embodiment of this application in detail with reference to the accompanying drawings.

[0026] Implementation method 1:

[0027] Figure 1-5 As shown, an integrated water tank with leakage detection function includes a water tank body 1 with an inlet pipe 2 and an outlet pipe 3 installed on the side.

[0028] Because leakage is common at the connection between the inlet pipe 2 and the outlet pipe 3 and the water tank body 1, this solution provides a protective pipe 4 on the outside of both the inlet pipe 2 and the outlet pipe 3. The protective pipe 4 is connected to the water tank body 1, and a water-stopping and expanding rubber 5 is fixed on the inner wall of the protective pipe 4. The water-stopping and expanding rubber 5 is a conventional water-absorbing and expanding material in the prior art, which has the characteristic of expanding when it comes into contact with water. It can quickly absorb water and expand after contact with water, thereby filling the gaps and achieving the purpose of stopping water leakage. Once leakage occurs at the connection of the inlet pipe 2 or the outlet pipe 3, the water-stopping and expanding rubber 5 can be used to temporarily seal the leakage point and reduce the risk of continuous leakage.

[0029] The inlet pipe 2 is equipped with a stop valve, and a valve handle 12 is rotatably mounted on the stop valve. A trigger pipe 10 is fixedly connected to the protective pipe 4. An expansion block 15 is provided inside the trigger pipe 10 near the protective pipe 4, which is in contact with the water-stopping expansion rubber 5. The ends of multiple trigger pipes 10 away from the protective pipe 4 are fixedly connected to an actuation pipe 11. A push rod 13 is slidably sealed at the end of the actuation pipe 11 away from the trigger pipe 10. A tension spring 14 is fixed between the push rod 13 and the actuation pipe 11. The inside of the trigger pipe 10 and the actuation pipe 11 is filled with compressed gas. When the push rod 13 slides outward, it pushes the valve handle 12 to rotate toward the side where the stop valve is closed.

[0030] When leakage occurs at the connection of the inlet pipe 2 or the outlet pipe 3, the expansion block 15 has the same characteristics as the water-stopping expansion rubber 5. By utilizing its water absorption and expansion characteristics, the air pressure in the trigger pipe 10 and the action pipe 11 increases, thereby causing the push rod 13 to push outward. The outward sliding push rod 13 pushes the valve handle 12 to rotate toward the side of the water-stopping valve, closing the water-stopping valve and effectively preventing further water intake, thereby reducing the risk of continuous leakage.

[0031] Of course, in addition to the above-mentioned leakage detection and response measures, leakage detection and prevention of water ingress can also be achieved by using conventional water leakage sensors and solenoid valves with controllers in the existing technology. Since existing water leakage sensors and solenoid valves with controllers have electrical instability, the above-mentioned structure of this solution can further improve the water tank leakage detection and response effect.

[0032] Among them, the trigger tube 10 is a transparent tube, and the end of the expansion block 15 away from the protective tube 4 is also connected to a color-changing silicone 19. For example, the blue silicone will change from blue to red or pink after absorbing moisture. The color-changing silicone 19 changes color when it comes into contact with water, and personnel can observe the specific water seepage location from the outside of the trigger tube 10.

[0033] Considering that the expansion of the water-stopping rubber 5 makes the protective tube 1 4 relatively fixed to the inlet pipe 2 or outlet pipe 3, making it difficult to disassemble and replace, a protective tube 2 7 is fitted on the outside of the protective tube 1 4. The side end of the protective tube 2 7 is threaded with a fixing knob 8 that abuts against the protective tube 1 4. The protective tube 2 7 can prevent the protective tube 1 4 from being damaged by external impact and is conducive to protecting the pipe interface. The protective tube 2 7, together with the fixing knob 8, can fix the protective tube 1 4. The protective tube 1 4 abuts against the outer wall of the water tank body 1. After the expansion of the water-stopping rubber 5, the protective tube 1 4 is relatively fixed to the inlet pipe 2 or outlet pipe 3. At this time, the fixing knob 8 can be loosened, and the protective tube 1 4 can be removed and replaced along with the inlet pipe 2 or outlet pipe 3.

[0034] Among them, the water-stopping expansion rubber 5 does not come into contact with the water inlet pipe 2 and the water outlet pipe 3, so as to avoid the water-stopping expansion rubber 5 from obstructing the normal installation of the protective pipe 4, the water inlet pipe 2 or the water outlet pipe 3. The water-stopping expansion rubber 5 is fixed with a water-absorbing sponge 6 that comes into contact with the water inlet pipe 2 and the water outlet pipe 3. The water-absorbing sponge 6 can ensure that when water seepage occurs, the water-stopping expansion rubber 5 can come into contact with the seepage water in time and thus expand.

[0035] For water that accidentally leaks to the outside of the protective pipe 4, a water-enclosing trough 16 is fixed to the lower periphery of the water tank body 1. A water collection tank 17 connected to the water-enclosing trough 16 is installed at the bottom of the water tank body 1. A return water pipe 18 is fixedly connected between the water collection tank 17 and the top of the water tank body 1. A water pump connected to the return water pipe 18 is installed inside the water collection tank 17. The water that accidentally leaks falls into the water-enclosing trough 16 and flows into the water collection tank 17 for collection. The water collected in the water collection tank 17 is pumped back into the water tank body 1 by the water pump in conjunction with the return water pipe 18, so as to avoid water waste.

[0036] In addition, considering the possibility of accidental splashing at the inlet pipe 2 or outlet pipe 3, splash guards 9 are fixedly fitted on both the inlet pipe 2 and the outlet pipe 3. The splash guards 9 are located on the side of the protective pipe 4 away from the water tank body 1. When splashing occurs at the inlet pipe 2 or outlet pipe 3, the splash guards 9 can effectively prevent water from splashing to the surroundings, thereby protecting the surrounding objects.

[0037] Compared to existing technologies, this solution provides a protective pipe 4 and a water-stopping expansion rubber 5 at the inlet pipe 2 or outlet pipe 3, and an action pipe 11 and a trigger pipe 10 between the inlet pipe 2 and outlet pipe 3. If leakage occurs at the connection of the inlet pipe 2 or outlet pipe 3, the water-stopping expansion rubber 5 expands upon contact with water, temporarily sealing the leakage point. Simultaneously, the expansion block 15 absorbs water and expands, causing an increase in air pressure in the trigger pipe 10 and the action pipe 11. This causes the push rod 13 to slide outward, pushing the valve handle 12 to rotate toward the side of the water-stop valve, closing the water-stop valve and effectively preventing further water intake, thereby reducing the risk of continuous leakage. Furthermore, any water that leaks out accidentally falls into the water-enclosing trough 16 and flows into the water collection tank 17 for collection. The water collected in the water collection tank 17 is then pumped back into the water tank body 1 using a water pump in conjunction with the return water pipe 18.

[0038] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
