Description

Technical Field

[0001] This invention belongs to the field of water leakage protection technology, specifically a mechanical water leakage protection device. By optimizing the structural design related to water leakage detection and plugging, the structure of the protection device is optimized. Background Technology

[0002] A water purifier's leak protection device is a device used to detect and prevent water purifier leaks. Its main function is to monitor the water flow in the water purifier system and take corresponding measures when a leak is detected to prevent losses and waste caused by water leakage. When the leak sensor detects a leak, it sends a signal to the shut-off device or valve to cut off the water supply, which can stop further water flow and reduce losses caused by leaks.

[0003] Existing leak protection devices typically use expansion cotton to detect leaks. Since the deformation of expansion cotton is usually irreversible, it needs to be manually replaced every time a leak is detected, which increases the maintenance cost of the device. In addition, existing protection devices usually completely block the pipe when a leak is detected. The subsequent water flow, under the action of inertia, will quickly reach the maximum pressure on the valve and pipe wall, which can easily lead to local overpressure in the pipe, causing pipe rupture, equipment damage, etc., reducing the safety of the protection device during operation. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a mechanical leakage protection device. This addresses the issues of existing leakage protection devices where the expansion cotton needs to be manually replaced, increasing maintenance costs, and where the device completely blocks the pipe when a leak occurs, potentially causing pipe rupture, equipment damage, and reduced safety during operation.

[0005] This invention provides the following technical solution:

[0006] Mechanical leakage protection devices include:

[0007] A base is provided, with a water pipe fixedly connected to the outer side wall of the base. An inlet pipe and an outlet pipe are fixedly connected to the top outer wall of the water pipe. The inlet pipe, the water pipe, and the outlet pipe are interconnected. The inlet pipe and the outlet pipe are used to provide channels for water to enter and exit. A sealing ring is fixedly connected to the inner wall of the inlet pipe and the outlet pipe to prevent water leakage.

[0008] The detection assembly includes a housing, a vent, a water inlet, a fixed post, a floating ring, a roller, a sliding block, a magnet, a first metal rod, a second metal rod, a third metal rod, and a current detector. The housing is fixedly connected to the outer side wall of the base. The vent is located on the top outer wall of the housing, and the water inlet is located on the bottom outer side wall of the housing. There are multiple vents and water inlets. The vent is used to expel excess air from the housing when the floating ring is pushed upward by water leakage. The fixed post is fixedly connected to the inner wall of the housing. The floating ring is fitted and slidably connected to the outer wall of the fixed post. The roller is rotatably connected to the inner wall of the floating ring. The sliding block is slidably connected to the inner wall of the fixed post. The magnet is fixedly connected to the outer wall of the sliding block. The first metal rod is fixedly connected to the inner wall of the sliding block. The second and third metal rods are both fixedly connected to the inner wall of the fixed post. They are located on both sides of the first metal rod and contact it to form a circuit. The current detector is fixedly connected to the bottom inner wall of the fixed post.

[0009] A leak-proof assembly includes a motor, a rotating column one, a groove one, a groove two, a telescopic rod, a spring, a baffle one, a connecting rod one, a rotating column two, a connecting rod two, a rotating column three, and a baffle two. The motor is fixedly connected to the outer side wall of the base. The rotating column one is fixedly connected to the outer wall of the motor's main shaft. The groove one is formed on one side of the outer wall of the rotating column one. The groove two is formed on the other side of the outer wall of the rotating column one. The telescopic rod is fixedly connected to the inner wall of the rotating column one. The spring is fixedly connected to the outer wall of the telescopic rod. The baffle one is fixedly connected to the outer walls of the telescopic rod and the spring. The connecting rod one is slidably connected to the inner wall of the rotating column one and fixedly connected to the outer wall of the baffle one. The rotating column two is rotatably connected to the inner wall of the connecting rod one. The connecting rod two is fixedly connected to the outer wall of the rotating column two. The rotating column three is fixedly connected to the outer wall of the connecting rod two and rotatably connected to the inner wall of the rotating column one. The baffle two is fixedly connected to the outer wall of the rotating column three.

[0010] Furthermore, the magnet is made of a magnetic material, which can attract the roller made of metal and keep it at the same height, thereby causing the sliding block to move up and down with the floating ring.

[0011] Furthermore, the current detector is equipped with a generator and a Hall sensor to generate current in the circuit composed of metal rod 2, metal rod 1, and metal rod 3, and to determine the height of the leaking water level by detecting its changes. The generator in the current detector generates current, metal rod 2 is used to receive the current input, metal rod 1 is used to transfer the current on metal rod 2 to metal rod 3, and metal rod 3 is used to transport the current transferred from metal rod 1 to the Hall sensor in the current detector, which monitors the current changes.

[0012] Furthermore, the third metal rod provides a greater resistance than the second metal rod, thereby reducing the impact of current changes caused by water surface fluctuations inside the housing on the current detector's detection results, achieving a "buffering" effect on current fluctuations, and improving the operational stability of the detection component.

[0013] Furthermore, the cross-section of the first groove is rectangular. When water flows normally through the water pipe, the motor drives the rotating column to rotate so that the first groove is directly opposite the inlet pipe and the outlet pipe, and the water flows from the inlet pipe through the first groove into the outlet pipe.

[0014] Furthermore, the cross-section of the second groove is triangular. When leakage occurs and it is necessary to stop the water flow, the motor drives the rotating column to rotate so that the second groove is directly opposite the inlet and outlet pipes. The water in the water pipe is blocked by the baffle. Since the angle between the edge of the cross-section of the second groove and the direction of the water pressure from the inlet pipe is acute, the water pressure always causes the rotating column to rotate clockwise, forming a self-locking effect of the rotation angle of the rotating column, which further enhances the leak-proof function of the leak-proof component.

[0015] Furthermore, the motor can drive the rotating column to rotate by a corresponding angle based on the water level height data provided by the detection component, thereby adjusting the water flow in the water pipe and achieving the function of preventing leakage without affecting the water transport function of the water pipe.

[0016] Furthermore, the shortest compression length of the spring is still greater than the inner diameter of the outlet pipe. Therefore, when the rotating column rotates so that the two sides of the groove face the inlet pipe and the outlet pipe, the water in the water pipe will be completely blocked by the baffle and cannot enter the outlet pipe. This achieves the effect of automatically preventing the water in the pipe from continuing to flow when leakage occurs.

[0017] Furthermore, when the baffle one blocks water that suddenly enters the groove two, the compression telescopic rod shortens, and the spring fixedly connected between the telescopic rod and the baffle one provides a buffering effect against the impact of the water flow due to its own elasticity, thus protecting the internal structure of the device.

[0018] Furthermore, when the baffle one slides, it drives the connecting rod one to slide to the left. Since the rotating column three is fixedly connected to the inner wall of the rotating column one by the rotating shaft and can rotate around it, when the connecting rod one slides to the left, it drives the baffle two to rotate through the connecting rod two. Multiple baffles two stand up to slow down the speed of the water flow in the groove two, and work with the baffle one to further reduce the damage caused by the water flow impact.

[0019] Furthermore, the greater the impact force of the water flow in the second groove, the longer the distance that the first baffle is pushed by it, and the closer the angle of rotation of the second baffle driven by the first connecting rod is to 90°. When the second baffle is perpendicular to the second groove, its blocking effect on the water flow is the greatest. Therefore, the combination of the second baffle and the first baffle can achieve an adaptive reduction effect of the water flow impact force.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The mechanical water leakage protection device of the present invention detects the changes in current on metal rods two and three by the floating ring inside the detection component rising and falling with the water level. The water level is calculated by detecting the changes in current through a current detector. The detection component automatically returns to its initial state after the leakage is cleared, achieving the effect of reusability of the detection component. This solves the problem that existing water leakage protection devices usually use expansion cotton to detect leaks. Since the deformation of expansion cotton is usually irreversible, it needs to be manually replaced every time a leak is detected, which increases the maintenance cost of the device. Moreover, the method of detecting current changes in this device is more rapid than the deformation of expansion cotton, which improves the detection efficiency. It is a reliable device that effectively prevents water leakage and improves electrical safety.

[0022] 2. The mechanical leakage protection device of this invention uses a motor to drive a rotating column to rotate inside the water pipe, causing groove one or groove two to face the inlet and outlet pipes, thus switching the channel on / off of the water pipe. By setting a baffle one connected to a spring in groove two, the baffle one is allowed to move to a certain extent when the water flow through groove two suddenly increases, achieving a buffering effect against the impact of water in the pipe. This solves the problem that existing protection devices usually completely block the pipe when encountering leakage, and the subsequent water flow, under the action of inertia, quickly reaches the maximum pressure on the valve and pipe wall, which can easily lead to local overpressure in the pipe, causing pipe rupture, equipment damage, etc., reducing the safety of the protection device during operation. This device protects the integrity of the pipe, extends the service life of the device, reduces maintenance costs, and improves the safety of the leakage protection system.

Detailed Implementation

[0036] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0037] This invention provides a mechanical leakage protection device, comprising:

[0038] The base 1 is used to support the entire device. A water pipe 2 is welded to the outer side wall of the base 1. A water inlet pipe 21 and a water outlet pipe 22 are welded to the top outer wall of the water pipe 2. The water inlet pipe 21, the water pipe 2, and the water outlet pipe 22 are interconnected. The water inlet pipe 21 and the water outlet pipe 22 are used to provide channels for water to enter and exit. A sealing ring 23 is fixed on the inner wall of the water inlet pipe 21 and the water outlet pipe 22 to prevent water leakage.

[0039] Existing leak protection devices typically use expanding cotton to detect leaks. The expanding cotton absorbs water and expands to lift the cover plate, causing the sealing core to be pushed open by a spring on the cover plate, blocking the water passage and cutting off water inflow. However, since the deformation of the expanding cotton is usually irreversible, it needs to be manually replaced after each leak, increasing the device's maintenance cost. This invention provides a solution to this problem: a detection component 3 for monitoring leaks, wherein the housing 31 is fixed to the outer side wall of the base 1 by screws, a vent 311 is opened on the top outer wall of the housing 31, and a water passage 312 is opened on the bottom outer side wall of the housing 31. The vent 311 and the water passage 312... There are multiple 2s. The vent 311 is used to expel excess air from the housing 31 when the floating ring 33 is pushed up by water leakage. The fixed column 32 is fixed to the inner wall of the housing 31 by screws. The floating ring 33 is sleeved and slides on the outer wall of the fixed column 32. The roller 331 rotates on the inner wall of the floating ring 33 through the rotating shaft. The sliding block 34 slides on the inner wall of the fixed column 32. The magnet 35 is fixed to the outer wall of the sliding block 34 by welding. The magnet 35 is made of magnetic material and can attract the roller 331 made of metal material, always keeping it at the same height, thereby driving the sliding block 34 to move up and down with the floating ring 33.

[0040] Metal rod 36 is welded to the inner wall of sliding block 34. Metal rods 37 and 38 are both welded to the inner wall of fixing post 32. They are located on both sides of metal rod 36 and contact it to form a circuit. Current detector 39 is welded to the bottom inner wall of fixing post 32. Current detector 39 contains a generator and a Hall sensor to generate current in the circuit composed of metal rods 37, 36, and 38. Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, when the floating ring 33 moves up or down, the sliding block 34 moves along with the magnetic block 35. Through the up and down movement, the circuit composed of metal rod 1 36, metal rod 2 37 and metal rod 38 also moves. The higher the height of metal rod 1 36, the longer the total length of the circuit. According to the principle that "when the cross-sectional area of ​​the resistor is constant, the longer the resistance wire, the greater the resistance, and the shorter the resistance wire, the smaller the resistance", it is known that the current detected by the current detector 39 changes with the height of metal rod 1 36. Therefore, the current detector 39 can determine the height of the floating ring 33 by detecting the current, thereby determining the height of the leaking water level. Since the detection component 3 is based on mechanical principles for leak detection, this mechanical design makes the device highly reusable. It can be used in multiple leak events without failure, has a long service life, is easy to maintain, and is suitable for various environmental conditions.

[0041] The generator inside the current detector 39 generates current, and the second metal rod 37 is used to receive the power input, preferably made of copper. The first metal rod 36 is used to transfer the current from the second metal rod 37 to the third metal rod 38. The third metal rod 38 is used to transport the current from the first metal rod 36 to the Hall sensor inside the current detector 39, which monitors the current change. This allows the leakage protection device to detect even small leaks with high sensitivity. Once a leakage event occurs, even if only a small amount of water touches the device, protective measures can be quickly activated to prevent the leakage accident from escalating further. The third metal rod 38 provides a greater resistance than the second metal rod 37 and is preferably made of aluminum, thereby reducing the impact of current changes caused by water surface fluctuations inside the housing 31 on the detection results of the current detector 39, achieving a "buffering" effect on current fluctuations and improving the operational stability of the detection component 3.

[0042] Existing valves typically completely block the pipe when leaking. Due to the smooth pipe wall, the subsequent water flow, under inertia, rapidly reaches its maximum pressure on the valve and pipe wall, causing damage—a phenomenon known as the "water hammer effect" in fluid mechanics. This pressure shock wave propagates along the pipe, easily leading to localized overpressure and causing pipe rupture, equipment damage, etc., reducing the safety of the protection device during operation. This invention provides a solution to this problem: a leak-proof component 4 to prevent further leakage. The motor 41 is fixed to the outer side wall of the base 1 with screws, and the rotating column 42 is welded to the outer wall of the motor 41's main shaft. A groove 421 is formed on one side of the outer wall of the rotating column 42. Figure 11 As shown, the cross-section of groove 421 is rectangular. When water flows normally through water pipe 2, motor 41 drives rotating column 42 to rotate, so that groove 421 is directly opposite the inlet pipe 21 and outlet pipe 22. Water flows from the inlet pipe 21 through groove 421 into the outlet pipe 22. Groove 422 is located on the other side of the outer wall of rotating column 42. The cross-section of groove 422 is triangular. When leakage occurs and it is necessary to stop the water flow, motor 41 drives rotating column 42 to rotate, so that groove 422 is directly opposite the inlet pipe 21 and outlet pipe 22. The water in water pipe 2 is blocked by baffle 432. Figure 11 As shown, since the angle between the cross-sectional edge of the groove 422 and the direction of the water pressure from the inlet pipe 21 is an acute angle, the water pressure always causes the rotating column 42 to rotate clockwise, forming a self-locking effect on the rotation angle of the rotating column 42, which further strengthens the anti-leakage function of the anti-leakage component 4; in addition, the motor 41 can drive the rotating column 42 to rotate by a corresponding angle according to the leakage water level height data provided by the detection component 3, thereby adjusting the water flow in the water pipe 2, so as to prevent leakage without affecting the function of the water pipe 2 in transporting water, and improve the operating efficiency of the device.

[0043] The telescopic rod 43 is fixed to the inner wall of the rotating column 42 by welding, and the spring 431 is fixed to the outer wall of the telescopic rod 43 by welding. The shortest compression length of the spring 431 is still greater than the inner diameter of the outlet pipe 22. Therefore, when the rotating column 42 rotates so that the groove 422 faces the inlet pipe 21 and the outlet pipe 22, as... Figure 10 As shown, the water in the water pipe 2 will be completely blocked by the baffle 432 and cannot enter the outlet pipe 22, thus automatically stopping the water from flowing in the pipe when a leak occurs. The baffle 432 is fixed to the outer wall of the telescopic rod 43 and the spring 431 by welding. When the baffle 432 blocks the water that suddenly enters the groove 422, the telescopic rod 43 is compressed and shortened. The spring 431 fixed between the telescopic rod 43 and the baffle 432 provides a buffering effect against the impact of the water flow due to its own elasticity, protecting the internal structure of the device and reducing the risk of damage to the pipe and the leak protection device.

[0044] Linkage 1 44 slides on the inner wall of rotating column 1 42 and is fixed to the outer wall of baffle 1 432 by welding. Rotating column 2 441 rotates on the inner wall of linking column 1 44 via a rotating shaft. Linking column 2 442 is fixed to the outer wall of rotating column 2 441 by welding. Rotating column 3 443 is fixed to the outer wall of link 2 442 by welding and rotates on the inner wall of rotating column 1 42 via a rotating shaft. Baffle 2 444 is fixed to the outer wall of rotating column 3 443 by welding. Figure 8 As shown, when baffle 1 432 slides, it drives connecting rod 1 44 to slide to the left. Since rotating column 3 443 is fixed to the inner wall of rotating column 1 42 by the rotating shaft and can rotate around it, when connecting rod 1 44 slides to the left, it drives baffle 2 444 to rotate through connecting rod 2 442. Figure 7 As shown, multiple baffles 444 are erected to slow down the water flow in the groove 422. Together with baffle 432, they further reduce the damage caused by the water flow impact. The greater the impact force of the water flow, the longer the distance that baffle 432 is pushed. This means that the angle at which baffle 444 is driven to rotate via connecting rod 44 is closer to 90°. When baffle 444 is perpendicular to the groove 422, its blocking effect on the water flow is the greatest. Therefore, the combination of baffle 444 and baffle 432 can achieve an adaptive reduction effect of water flow impact force, further reducing the impact on the leakage protection device, extending its service life, and reducing the frequency of replacement and maintenance.

[0045] In summary, this invention detects the changes in current on metal rods 37 and 38 caused by the floating ring 33 within the detection component 3 rising and falling with the water level. The water level is then calculated by the current detector 39 based on these current changes. The detection component 3 automatically returns to its initial state after the leak is cleared, making it reusable. This solves the problem of existing leak protection devices that typically use expansion cotton for leak detection, where deformation is often irreversible and requires manual replacement, increasing maintenance costs. Furthermore, this device improves detection efficiency and is a reliable device that effectively prevents water loss and enhances electrical safety. The motor 41 drives the rotating column 42 to rotate within the water pipe 2, causing the groove 421 or groove 422 to... The device switches the water inlet pipe 21 and outlet pipe 22, thus achieving the effect of switching the channel in the water pipe 2. By setting a baffle 432 connected to the spring 431 in the groove 2 422, the baffle 432 is allowed to move to a certain extent when the water flow through the groove 2 422 suddenly increases. This achieves a buffering effect on the impact of water in the pipe, solving the problem that existing protection devices usually completely block the pipe when encountering water leakage. The subsequent water flow, under the action of inertia, quickly reaches the maximum pressure on the valve and pipe wall, which can easily lead to local overpressure in the pipe, causing pipe rupture, equipment damage, etc., and reducing the safety of the protection device during operation. This device protects the integrity of the pipe, extends the service life of the device, reduces maintenance costs, and improves the safety of the leakage protection system.

The mechanical leakage protection device as described in claim 6, characterized in that: The shortest compression length of the spring (431) is still greater than the inner diameter of the outlet pipe (22). Therefore, when the rotating column (42) rotates so that the groove (422) faces the inlet pipe (21) and the outlet pipe (22), the water in the water pipe (2) will be completely blocked by the baffle (432) and cannot enter the outlet pipe (22). This achieves the effect of automatically preventing the water in the pipe from continuing to flow when leakage occurs.

8. The mechanical leakage protection device as described in claim 7, characterized in that: When the baffle (432) blocks water that suddenly enters the groove (422), the compression telescopic rod (43) shortens, and the spring (431) fixedly connected between the telescopic rod (43) and the baffle (432) provides a buffering effect against the impact of the water flow due to its own elasticity, thus protecting the internal structure of the device.

9. The mechanical leakage protection device as described in claim 6, characterized in that: When the baffle 1 (432) slides, it drives the connecting rod 1 (44) to slide to the left. Since the rotating column 3 (443) is fixedly connected to the inner wall of the rotating column 1 (42) by the rotating shaft and can rotate around it, when the connecting rod 1 (44) slides to the left, it drives the baffle 2 (444) to rotate through the connecting rod 2 (442). Multiple baffles 2 (444) stand up to slow down the speed of water flow in the groove 2 (422), and work with the baffle 1 (432) to further reduce the damage caused by the impact of water flow.

10. The mechanical leakage protection device as described in claim 9, characterized in that: The greater the impact force of the water flow in the second groove (422), the longer the distance that the first baffle (432) is pushed by it, and the closer the angle of rotation of the second baffle (444) driven by the first connecting rod (44) is to 90°. When the second baffle (444) is perpendicular to the second groove (422), its blocking effect on the water flow is the greatest. Therefore, the combination of the second baffle (444) and the first baffle (432) can achieve an adaptive reduction effect of the impact force of the water flow.
