A type of urban water supply and drainage pipe

Abstract

This invention belongs to the field of pipeline technology, specifically an urban water supply and drainage pipe, including a torque control box. A water storage device is fixedly connected to the bottom of the torque control box. The torque control box includes a protective outer shell, and a torque gear is rotatably connected to the middle of the upper part of the inner wall of the protective shell. A torque rotating rod is fixedly connected to the axis of the torque gear. Control gears are symmetrically arranged on the left and right sides of the outer surface of the torque gear. This device can control the rotation of an auxiliary motor to control the water storage tank for drainage and water storage.

During drainage, the water outlet above the water transfer box is blocked by a staggered rotating waterproof cover, preventing water from entering the water storage tank and thus preventing contamination of the clean water inside the tank.

Description

Technical Field

[0001] This invention belongs to the field of pipeline technology, specifically a type of urban water supply and drainage pipe. Background Technology

[0002] With urban development, water supply and drainage pipes play an increasingly important role in urban construction, and the market offers a diverse range of types. Different drainage pipes have different characteristics and properties, and serve different purposes in use.

[0003] To save space, more and more cities are adopting composite pipes, namely integrated water supply and drainage pipes. These pipes connect to the main pipes through different branch pipes and then switch between them to achieve the functions of water supply and drainage. However, water supply pipes need to withstand water pressure from the water source. Ordinary pipes will leak after being subjected to strong water pressure for a long time, resulting in poor reliability. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the prior art, the present invention provides an urban water supply and drainage pipe that solves the problem of water leakage and poor reliability of ordinary pipes after being subjected to strong water pressure for a long time.

[0006] (II) Technical Solution

[0007] The technical solution adopted by the present invention to solve its technical problem is: the urban water supply and drainage pipe of the present invention includes a torque control box, and a water storage device is fixedly connected to the bottom end of the torque control box.

[0008] Preferably, the torque control box includes a protective shell. A torque gear is rotatably connected to the middle of the upper part of the inner wall of the protective shell. A torque rod is fixedly connected to the axis of the torque gear. Control gears are symmetrically arranged on the left and right sides of the outer surface of the torque gear. An auxiliary motor is fixedly connected to the axis of the control gear. When water supply is required, the user starts the upper auxiliary motor. The left auxiliary motor controls the lower control gear to rotate clockwise, and the right auxiliary motor controls the lower control gear to rotate counterclockwise. Therefore, the entire torque gear rotates counterclockwise, which in turn controls the torque rod to rotate counterclockwise. Since the water tank is very heavy when full of water, two auxiliary motors are provided to ensure sufficient torque. This device can control the water tank to drain and store water by controlling the rotation of the auxiliary motors. Furthermore, the water tank has good sealing performance due to its own weight and the weight of the water inside. It is difficult for the water inside to flow out through the opening at the bottom of the water tank, thus improving the reliability of water supply.

[0009] Preferably, the water storage device includes a water storage tank, an inner wall of which is provided with a detection device, a snap-fit ​​ring fixedly connected to the upper part of the outer surface of the water storage tank, a transition ring provided inside the snap-fit ​​ring, a spherical groove evenly formed in the inner cavity of the transition ring, and ball bearings evenly arranged in the spherical grooves within the inner cavity of the transition ring, a connecting rod fixedly connected to the axis at the lower surface of the water storage tank, hollow metal tubes evenly arranged on the lower surface of the water storage tank, and a rotating waterproof cap fixedly connected to the bottom end of the hollow metal tube. The inner wall of the waterproof cover is rotatably connected to a water supply device. A torque lever controls the lower water tank to rotate counterclockwise. The upper surface of the water tank rotates within the inner wall of the locking ring via an adapter ring. The ball bearings reduce rotational friction. When supplying water, the device utilizes the strong water pressure inside the water tank to automatically inject the water into the water source transfer tank, and then transports it to various branch pipes through the outlet pipe to achieve the water supply effect. Therefore, the water supply process can flush the device below and solve the problem of pipe blockage.

[0010] Preferably, the water supply device includes a water source transfer box. Water outlets are evenly distributed on the side of the inner wall of the water source transfer box. Water outlet pipes are evenly distributed on the inner wall of the water source transfer box through the water outlets. Pressure testing ports are evenly distributed on the side of the inner wall of the water source transfer box. Drainage devices are evenly distributed on the inner wall of the water source transfer box through the pressure testing ports. The bottom of the water storage tank is controlled by a connecting rod to rotate the waterproof cover until the bottom ends of the four hollow metal pipes are connected to the water inlet on the upper surface of the water source transfer box. At this point, the auxiliary motor stops rotating. Water inside the water storage tank enters the interior of the water source transfer box through the hollow metal pipes under its own water pressure, and is then discharged to the outside through the water outlet pipes, achieving the water supply effect. After water supply is completed, the auxiliary motor rotates again, offsetting the opening on the inner wall of the waterproof cover from the opening on the upper surface of the water source transfer box, so that the water storage tank is in a water-storing state.

[0011] Preferably, the upper part of the outer surface of the torque rod is fixedly connected to the axis of the inner wall of the torque gear column, the bottom end of the torque rod is fixedly connected to the axis of the upper surface of the water storage tank, the outer surface of the torque gear column meshes with the outer surface of the control gear column, there are two torque gear columns, the outer surface of the auxiliary motor output shaft is fixedly connected to the axis of the inner wall of the control gear column, the upper surface of the auxiliary motor is fixedly connected to the upper part of the inner wall of the protective shell, and the upper surface of the protective shell is fixedly connected to the lower surface of the ceiling. Under normal conditions, the opening of the inner wall of the rotating waterproof cover is offset from the opening of the upper surface of the water source transfer box, so water can be injected into the water storage tank to fill the water storage tank completely, while the bottom opening of the hollow metal tube is blocked by the upper surface of the water source transfer box, so the water inside the water storage tank is in a closed state.

[0012] Preferably, the outer surface of the ball bearing is rotatably connected to the outer surface of the snap ring, the outer surface of the ball bearing is rollingly connected to the inner wall of the snap ring through a spherical groove, the bottom of the inner wall of the water storage tank is evenly provided with insertion ports, the number of hollow metal tubes is four, the top end of the hollow metal tube is fixedly connected to the bottom of the inner cavity of the water storage tank through the insertion port, and the bottom end of the hollow metal tube is fixedly connected to the inner wall of the rotating waterproof cover.

[0013] Preferably, the upper part of the inner wall of the water transfer box is provided with a water inlet, the upper part of the outer surface of the water transfer box is rotatably connected to the inner wall of the rotating waterproof cover, the number of water outlet pipes is four, the top of the water outlet pipes is fixedly connected to the inner wall of the water transfer box through the water outlet, the number of water drainage devices is four, and the included angle between the water outlet pipes and the water drainage devices is 30°.

[0014] Preferably, the detection device includes an air cushion disc with an annular groove on its side. A magnetic ring is fixedly connected to the side of the air cushion disc through the annular groove. Vertical grooves are symmetrically formed on the left and right sides of the outer surface of the water storage tank. Indicating metal balls are symmetrically arranged on the left and right sides of the outer surface of the water storage tank through the vertical grooves. A spring cylinder is fixedly connected to the lower surface of the air cushion disc. When water is injected into the water storage tank, the air cushion disc will float under the buoyancy of the water. During this process, the spring cylinder is also pulled upward to prevent the air cushion disc from tipping over and to ensure that the air cushion disc rises smoothly. When the cushion plate floats, the indicator metal ball on the side rises with it due to the magnetic attraction of the magnetic ring. Similarly, when the water level inside the tank decreases, the cushion plate descends, and the indicator metal ball on the side also descends due to the magnetic attraction of the magnetic ring. Because the tank is usually large, the water level inside is difficult to observe from the outside. The indicator metal ball acts as an indicator scale, remaining almost parallel to the water level inside the tank. Therefore, personnel can easily understand the water level inside the tank from the outside by observing the position of the indicator metal ball and determine whether water needs to be added.

[0015] Preferably, the inner cavity of the air cushion disc is evenly provided with openings, the bottom end of the spring cylinder is fixedly connected to the lower part of the inner wall of the water storage tank, the number of the indicator metal balls is two, the outer surface of the indicator metal balls is slidably connected to the outer surface of the air cushion disc through a vertical sliding groove, and the outer surface of the water storage tank is symmetrically provided with scales through a vertical sliding groove.

[0016] Preferably, the drain device includes an arc-shaped block with symmetrically arranged extension plates on its sides. A symmetrical spring assembly is fixedly connected to the upper surface of the extension plates. When the water storage tank is in a water-storing state, if the branch water pipe connected to the bottom end of the outlet pipe is blocked, the wastewater inside the branch water pipe will enter the interior of the water source transfer tank from the outlet pipe. The water outlet at the top of the water source transfer tank is blocked by the staggered rotating waterproof cover and cannot enter the water storage tank. Therefore, the water pressure inside the water source transfer tank increases. When the water pressure is too high, the arc-shaped block of the drain device is pushed outward by the water pressure, and the wastewater is discharged to the outside through the interior of the arc-shaped block, thus providing another discharge channel for the wastewater. After the wastewater is discharged, the symmetrical spring assemblies on both sides of the arc-shaped block reset and push the arc-shaped block into the interior of the water source transfer tank, and the water source transfer tank is blocked again.

[0017] Preferably, the inner cavity of the arc-shaped block is provided with a drainage groove, and the inner wall of the arc-shaped block is provided with a through-hole evenly on the side near the connecting rotating rod. There are two symmetrical spring groups. The top of the symmetrical spring groups is fixedly connected to the inner wall of the water source transfer box, and the side of the arc-shaped block is slidably connected to the inner wall of the water source transfer box through a pressure measuring port.

[0018] Preferably, the outer surface of the snap ring is rotatably connected to the inner wall of the ground, and a water inlet is provided at the upper part of the inner wall of the water storage tank.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. This device can control the rotation of the auxiliary motor to control the water tank to drain and store water. Under the pressure of the weight of the water tank itself and the weight of the water inside, the sealing performance is good, and the water inside is difficult to flow out through the opening at the bottom of the water tank, thus improving the reliability of the water supply operation.

[0021] 2. The device integrates water supply and drainage functions. During drainage, the water outlet at the top of the water transfer box is blocked by a staggered rotating waterproof cover, preventing water from entering the storage tank and thus preventing the clean water inside the storage tank from being contaminated.

[0022] 3. When supplying water, the device uses the strong water pressure inside the storage tank to automatically inject the water inside the storage tank into the water source transfer box, and then transports it to each branch pipe through the outlet pipe to achieve the water supply effect. Therefore, the water supply process can flush the device below and solve the problem of pipe blockage.

[0023] 4. The control gear column rotates counterclockwise, so the entire torque gear column rotates counterclockwise, which in turn controls the torque lever to rotate counterclockwise. Since the water tank is very heavy when full of water, two auxiliary motors are set up to ensure that the torque force is large enough. The torque lever controls the water tank below to rotate counterclockwise. The upper surface of the water tank rotates in the inner wall of the snap ring through the adapter ring. The ball bearings reduce the rotational friction, thereby reducing the working power of the auxiliary motor and reducing energy consumption.

[0024] 5. This device not only enables basic water supply and drainage functions, but also allows for the opening of an alternative drainage route to discharge wastewater in the event of blockage in the branch water pipe at the bottom, thus increasing emergency options and enhancing the device's practicality.

[0025] 6. Because water tanks are usually large, the water level inside is difficult to observe from the outside. The indicator metal ball acts as an indicator scale and is almost parallel to the water level inside the tank. Therefore, relevant personnel can observe the position of the indicator metal ball to easily understand the water level inside the tank from the outside and determine whether water needs to be added.

[0033] use Figures 1-6 An urban water supply and drainage pipe according to one embodiment of the present invention will be described as follows.

[0034] like Figures 1-6 As shown, the urban water supply and drainage pipe of the present invention includes a torque control box 1, and a water storage device 2 is fixedly connected to the bottom end of the torque control box 1.

[0035] The torque control box 1 includes a protective shell 11. A torque gear 12 is rotatably connected to the middle of the upper part of the inner wall of the protective shell 11. A torque rod 13 is fixedly connected to the axis of the torque gear 12. Control gears 15 are symmetrically arranged on the left and right sides of the outer surface of the torque gear 12. An auxiliary motor 14 is fixedly connected to the axis of the control gear 15. When water supply is required, the user starts the upper auxiliary motor 14. The left auxiliary motor 14 controls the lower control gear 15 to rotate clockwise, and the right auxiliary motor 14 controls the lower control gear 15 to rotate counterclockwise. Therefore, the entire torque gear 12 rotates counterclockwise, thereby controlling the torque rod 13 to rotate counterclockwise. This device can control the water tank 21 to drain and store water by controlling the rotation of the auxiliary motor 14.

[0036] The water storage device 2 includes a water storage tank 21. A detection device 3 is installed on the inner wall of the water storage tank 21. A snap-fit ​​ring 23 is fixedly connected to the upper part of the outer surface of the water storage tank 21. A transition ring 22 is installed inside the snap-fit ​​ring 23. Spherical grooves are evenly distributed within the inner cavity of the transition ring 22. Ball bearings 24 are evenly distributed within the spherical grooves within the inner cavity of the transition ring 22. A connecting rod 26 is fixedly connected to the axis at the lower surface of the water storage tank 21. Hollow metal tubes 25 are evenly distributed on the lower surface of the water storage tank 21. A rotating waterproof cover 27 is fixedly connected to the bottom end of the metal pipe 25. A water supply device 4 is rotatably connected to the inner wall of the rotating waterproof cover 27. The torque rod 13 controls the water storage tank 21 below to rotate counterclockwise. The upper surface of the water storage tank 21 rotates in the inner wall of the snap ring 23 through the adapter ring 22. The ball bearing 24 reduces the rotational friction. When supplying water, the device uses the strong water pressure inside the water storage tank 21 to automatically inject the water inside the water source transfer box 41.

[0037] The water delivery device 4 includes a water transfer box 41. Water outlets are evenly distributed on the side of the inner wall of the water transfer box 41. Water outlet pipes 42 are evenly distributed on the inner wall of the water transfer box 41 through the water outlets. Pressure testing ports are evenly distributed on the side of the inner wall of the water transfer box 41. Drainage devices 5 are evenly distributed on the inner wall of the water transfer box 41 through the pressure testing ports. The bottom of the water storage tank 21 is controlled by a connecting rod 26 to rotate the waterproof cover 27 until the bottom ends of the four hollow metal pipes 25 are connected to the water... When the water inlet on the upper surface of the water transfer box 41 is connected, the auxiliary motor 14 stops rotating. At this time, the water inside the water storage tank 21 enters the interior of the water transfer box 41 through the hollow metal pipe 25 under its own water pressure, and then is discharged to the outside through the water outlet pipe 42 to achieve the water supply effect. After the water supply is completed, the auxiliary motor 14 rotates, and the opening of the inner wall of the rotating waterproof cover 27 is once again offset from the opening on the upper surface of the water transfer box 41, so that the water storage tank 21 is in a water storage state.

[0038] The upper part of the outer surface of the torque rod 13 is fixedly connected to the axis of the inner wall of the torque gear 12. The bottom end of the torque rod 13 is fixedly connected to the axis of the upper surface of the water storage tank 21. The outer surface of the torque gear 12 meshes with the outer surface of the control gear 15. There are two torque gears 12. The outer surface of the output shaft of the auxiliary motor 14 is fixedly connected to the axis of the inner wall of the control gear 15. The upper surface of the auxiliary motor 14 is fixedly connected to the upper part of the inner wall of the protective shell 11. The upper surface of the protective shell 11 is fixedly connected to the lower surface of the ceiling. Under normal conditions, the opening of the inner wall of the rotating waterproof cover 27 is offset from the opening on the upper surface of the water source transfer box 41, so water can be injected into the water storage tank 21 to fill the water storage tank 21. The bottom opening of the hollow metal tube 25 is blocked by the upper surface of the water source transfer box 41, so the water inside the water storage tank 21 is in a closed state.

[0039] The outer surface of the ball bearing 24 is rotatably connected to the outer surface of the snap ring 23. The outer surface of the ball bearing 24 is rotatably connected to the inner wall of the adapter ring 22 through a spherical groove. The bottom of the inner wall of the water tank 21 is evenly provided with inlets. There are four hollow metal tubes 25. The top end of the hollow metal tube 25 is fixedly connected to the bottom of the inner cavity of the water tank 21 through the inlet. The bottom end of the hollow metal tube 25 is fixedly connected to the inner wall of the rotating waterproof cover 27.

[0040] The upper part of the inner wall of the water transfer box 41 is provided with a water inlet. The upper part of the outer surface of the water transfer box 41 is rotatably connected to the inner wall of the rotating waterproof cover 27. There are four water outlet pipes 42. The top of the water outlet pipes 42 is fixedly connected to the inner wall of the water transfer box 41 through the water outlet. There are four water drainage devices 5. The angle between the water outlet pipes 42 and the water drainage devices 5 is 30°.

[0041] The detection device 3 includes an air cushion disc 31. An annular groove is formed on the side of the air cushion disc 31, and a magnetic ring 32 is fixedly connected to the side of the air cushion disc 31 through the annular groove. Vertical grooves are symmetrically formed on the left and right sides of the outer surface of the water storage tank 21, and indicator metal balls 34 are symmetrically arranged on the left and right sides of the outer surface of the water storage tank 21 through the vertical grooves. A spring cylinder 35 is fixedly connected to the lower surface of the air cushion disc 31. When water is injected into the water storage tank 21, the air cushion disc 31 will... Under the action of buoyancy, it floats upward. During this process, the spring cylinder 35 is also pulled upward to prevent the air cushion plate 31 from tipping over and to ensure that the air cushion plate 31 rises steadily. When the air cushion plate 31 floats, the side indicator metal ball 34 also rises with the air cushion plate 31 under the magnetic attraction of the magnetic ring 32. Similarly, when the water volume inside the water tank 21 decreases, the air cushion plate 31 descends, and the side indicator metal ball 34 also descends with the air cushion plate 31 under the magnetic attraction of the magnetic ring 32.

[0042] The inner cavity of the air cushion pan 31 is evenly provided with openings. The bottom end of the spring cylinder 35 is fixedly connected to the lower part of the inner wall of the water storage tank 21. There are two indicating metal balls 34. The outer surface of the indicating metal balls 34 is slidably connected to the outer surface of the air cushion pan 31 through a vertical slide groove. The outer surface of the water storage tank 21 is symmetrically provided with scales 33 through a vertical slide groove.

[0043] The drain device 5 includes an arc-shaped block 51. An extension plate 52 is symmetrically arranged on the side of the arc-shaped block 51. A symmetrical spring assembly 53 is fixedly connected to the upper surface of the extension plate 52. When the water storage tank 21 is in a water storage state, if the branch water pipe connected to the bottom end of the outlet pipe 41 is blocked, the wastewater inside the branch water pipe will enter the water source transfer box 41 from the outlet pipe 41. The water outlet at the top of the water source transfer box 41 is blocked by the offset rotating waterproof cover 27 and cannot enter the water storage tank 21. Therefore, the water pressure inside the water source transfer box 41 increases. When the water pressure is too high, the arc-shaped block 51 of the drain device 5 is pushed outward by the water pressure, and the wastewater is discharged to the outside through the inside of the arc-shaped block 51, thus providing another discharge channel for the wastewater. After the wastewater is discharged, the symmetrical spring assembly 53 on both sides of the arc-shaped block 51 resets and pushes the arc-shaped block 51 into the inside of the water source transfer box 41, and the water source transfer box 41 is blocked again.

[0044] The inner cavity of the arc-shaped block 51 is provided with a drainage groove, and the inner wall of the arc-shaped block 51 is provided with a through-hole evenly on the side near the connecting rotating rod 26. There are two symmetrical spring groups 53. The top of the symmetrical spring group 53 is fixedly connected to the inner wall of the water source transfer box 41, and the side of the arc-shaped block 51 is slidably connected to the inner wall of the water source transfer box 41 through the pressure measuring port.

[0045] The outer surface of the snap ring 23 is rotatably connected to the inner wall of the ground, and a water inlet is provided on the upper part of the inner wall of the water storage tank 21.

[0046] The specific workflow is as follows:

[0047] In normal operation, the opening on the inner wall of the rotating waterproof cover 27 is offset from the opening on the upper surface of the water transfer box 41, allowing water to be filled into the water tank 21. The bottom opening of the hollow metal tube 25 is blocked by the upper surface of the water transfer box 41, keeping the water inside the water tank 21 sealed. When water supply is required, the user activates the upper auxiliary motor 14. The left auxiliary motor 14 controls the lower control gear 15 to rotate clockwise, and the right auxiliary motor 14 controls the lower control gear 15 to rotate counterclockwise. This causes the torque gear 12 to rotate counterclockwise, which in turn controls the torque lever 13 to rotate counterclockwise. Since the water tank 21 is very heavy when full, two auxiliary motors 14 are used to ensure sufficient torque.

[0048] The torque lever 13 controls the water storage tank 21 below to rotate counterclockwise. The upper surface of the water storage tank 21 rotates in the inner wall of the snap ring 23 through the adapter ring 22. The ball bearing 24 reduces the rotational friction. The bottom end of the water storage tank 21 controls the rotation of the waterproof cover 27 through the connecting lever 26 until the bottom ends of the four hollow metal pipes 25 are connected to the water inlet on the upper surface of the water transfer box 41. The auxiliary motor 14 stops rotating. At this time, the water inside the water storage tank 21 enters the interior of the water transfer box 41 from the hollow metal pipes 25 under its own water pressure, and then is discharged to the outside through the outlet pipe 42 to achieve the water supply effect. After the water supply is finished, the auxiliary motor 14 rotates again to offset the opening of the inner wall of the waterproof cover 27 from the opening on the upper surface of the water transfer box 41, so that the water storage tank 21 is in a water storage state.

[0049] When the water storage tank 21 is in a water storage state, if the branch water pipe connected to the bottom end of the outlet pipe 41 is blocked, the wastewater inside the branch water pipe will enter the water source transfer box 41 from the outlet pipe 41. However, the water outlet at the top of the water source transfer box 41 is blocked by the offset rotating waterproof cover 27 and cannot enter the water storage tank 21. Therefore, the water pressure inside the water source transfer box 41 increases. When the water pressure is too high, the arc-shaped block 51 of the drain device 5 is pushed outward by the water pressure, and the wastewater is discharged to the outside through the inside of the arc-shaped block 51, thus providing another discharge channel for the wastewater. After the wastewater is discharged, the symmetrical spring assembly 53 on both sides of the arc-shaped block 51 resets and pushes the arc-shaped block 51 into the inside of the water source transfer box 41, and the water source transfer box 41 is blocked again.

[0050] When water is injected into the water tank 21, the air cushion plate 31 will float up under the buoyancy of the water. During this process, the spring cylinder 35 is also pulled up to prevent the air cushion plate 31 from tipping over and to ensure that the air cushion plate 31 rises steadily. When the air cushion plate 31 floats up, the side indicator metal ball 34 also rises with the air cushion plate 31 under the magnetic attraction of the magnetic ring 32. Similarly, when the water level inside the water tank 21 decreases, the air cushion plate 31 falls down, and the side indicator metal ball 34 also falls down with the air cushion plate 31 under the magnetic attraction of the magnetic ring 32. The indicator metal ball 34 acts as an indicator scale 33, allowing relevant personnel to easily observe the water level inside the water tank 21 from the outside.
