Description

Technical Field

[0001] The invention belongs to the technical field of water supply and drainage pipelines, and specifically relates to a water supply and drainage control device and a use method thereof. Background Art

[0002] With the development of the construction industry, the role of water supply and drainage systems in construction projects is becoming increasingly important. In cold winter weather or in high-altitude cold areas in the north, building water supply and drainage pipes face the problem of pipe freezing due to low temperatures, especially for pipes installed outside the building, which are in direct contact with the outside air. The freezing phenomenon is more serious, affecting the normal use of the pipes and may even cause pipe ruptures and floods.

[0003] A Chinese patent application CN114482202B discloses an antifreeze structure for a building water supply and drainage system. The technical solution includes a reserved pipe, a reserved nested piece, a fixed protrusion, a docking piston, a drainage channel and a docking drive shaft. The inner end of the reserved pipe is provided with a drainage channel, and the inner surface of the reserved pipe is penetrated and installed with a docking drive shaft, and the outer end of the docking drive shaft is fixedly connected with a movable blade, and the movable blade is arranged on the inner side of the reserved pipe. The antifreeze structure for a building water supply and drainage system is provided with symmetrically distributed movable blades. The movable blades in contact with the water force will rotate with the water flow force, and then cooperate with the active state between the docking movable disk and the docking piston, and supply air to the inside of the nested docking piece through the U-shaped pipe, so that the multiple reserved foam spheres in contact with the inside form a fit and activity phenomenon, so that the water flow in contact forms a short-term heat supply treatment, and avoids the phenomenon of freezing of the water pipe due to low temperature.

[0004] However, the above-mentioned technologies often have the following defects: the water supply and drainage antifreeze structure drives the fan blades to rotate by water flow, so that the reserved spheres generate heat by friction with each other, thereby preventing water from freezing. However, the way of generating heat by friction is relatively unstable. When driving the fan blades to rotate, the water flow will increase the resistance to water flow, and it can only be effective when the water inside the pipe is in a flowing state. Therefore, it will not work if the water remains still. For example, when the valve of the water supply pipe is closed, the water in the pipe is in a non-flowing state. At this time, the above-mentioned technology cannot guarantee that the water will not freeze.

[0005] To this end, the present invention provides a water supply and drainage control device and a method for using the same. Summary of the invention

[0018] Preferably, water-conducting cotton pieces are provided on the inner wall of the bottom of the sheath at positions corresponding to the spiral grooves; two ends of the water-conducting cotton pieces respectively span the spiral grooves and are fixedly connected to the inner wall of the sheath.

[0026] 1. The present invention discloses a water supply and drainage control device and a method of using the same. When sunlight shines on the surface of the vacuum collector tube, the water inside the tube will be heated and gradually converted into high-temperature water vapor. After the steam rises, it enters the hollow structure of the sheath through the gas pipe and then moves inside the sheath along the length of the tube, thereby heating the outdoor portion of the tube so that the water therein can maintain a certain temperature in cold weather, thereby reducing the freezing phenomenon, maintaining normal water supply and drainage functions and preventing damage to the tube. The device converts solar energy into the thermal energy of water vapor to heat the water in the water pipe, thereby improving the heating stability of the water.

[0028] 3.

DETAILED DESCRIPTION

[0040] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0041] like Figures 1 to 8 As shown, a water supply and drainage control device according to the present invention comprises a control seat 1, a pipe 2 and an antifreeze component; the pipe 2 passes through the control seat 1 and is fixedly connected thereto;

[0042] The antifreeze assembly is used to increase the temperature of water inside the pipe 2 and prevent it from freezing; the antifreeze assembly includes a vacuum heat collecting pipe 3 and a sheath 4;

[0043] The vacuum heat collecting tube 3 is provided in a group and fixedly connected to the side of the control seat 1; pure water is added inside the vacuum heat collecting tube 3; the sheath 4 is provided on the outside of the pipeline 2; the sheath 4 is designed as a hollow structure; the hollow structure of the sheath 4 and the vacuum heat collecting tube 3 are connected to each other through the air pipe 5.

[0044] The water supply and drainage antifreeze structure in the prior art drives the fan blades to rotate by water flow, so that the reserved spheres generate heat by friction with each other, thereby preventing water from freezing. However, the method of generating heat by friction is relatively unstable. When the water flow drives the fan blades to rotate, the resistance to water flow will increase, and it can only be effective when the water inside the pipe 2 is in a flowing state. Therefore, it cannot work if the water remains stationary. For example, when the valve of the water supply pipe 2 is closed, the water in the pipe 2 is in a non-flowing state. At this time, the above technology cannot guarantee that the water will not freeze.

[0045] The present invention is mainly aimed at water supply and drainage pipelines located outdoors. On the one hand, the sheath 4 can protect the pipeline 2. On the other hand, when sunlight shines on the surface of the vacuum collector tube 3, the water inside it will be heated and gradually converted into high-temperature water vapor. After the steam rises, it enters the hollow structure of the sheath 4 through the gas pipe 5, and then moves inside the sheath 4 along the length of the pipeline 2, so that the part of the pipeline 2 located outdoors can be heated, so that the water therein can maintain a certain temperature in cold weather, thereby reducing its freezing phenomenon, maintaining normal water supply and drainage functions and preventing damage to the pipeline 2. The device converts solar energy into the heat energy of water vapor to heat the water in the water pipe, thereby improving the heating stability of the water. Regardless of whether the water is in a flowing state or a stationary state, the device can be used to prevent the water from freezing, reducing the limitations of the antifreeze component.

[0046] The outer layer of the jacket 4 is made of a heat-insulating material 6, such as glass fiber, rock wool, rubber foam, etc.; the inner layer of the jacket 4 is made of a good heat-conducting material 7, such as heat-conducting plastic, heat-conducting polymer, etc. By providing the heat-insulating material 6, it is possible to prevent the heat inside the jacket 4 from diffusing outward through the outer layer, reduce the heat loss of water vapor, and improve the thermal insulation effect. By providing the good heat-conducting material 7, it is possible to improve the heat exchange efficiency between the water vapor and the pipe 2, promote the heat transfer from the water vapor to the water inside the pipe 2, and further prevent it from freezing.

[0047] As a preferred embodiment of the present invention, a water collecting cylinder 8 is provided below the jacket 4; the bottom of the jacket 4 and the water collecting cylinder 8 are connected to each other through a collecting pipe 9. After the water vapor exchanges heat with the pipe 2 inside the jacket 4, it will gradually condense, and then the condensed water will gradually flow to the bottom of the jacket 4 and enter the water collecting cylinder 8 through the collecting pipe 9, so that the condensed water is collected.

[0048] The surface of the control seat 1 is rotatably connected with a rotating wheel 10 at a position corresponding to the water collecting tube 8; a group of convex blocks 11 with arc surfaces are evenly distributed on the circumference of the rotating wheel 10; a motor for driving the rotating wheel 10 is arranged inside the control seat 1;

[0049] The water collecting tube 8 and the vacuum heat collecting tube 3 are connected to each other through the return pipe 12; both the collecting pipe 9 and the return pipe 12 are provided with a one-way valve;

[0050] A movable part 13 is provided inside the water collecting barrel 8, and the movable part 13 and the water collecting barrel 8 are slidingly sealed together; a spring 14 is fixedly connected between the movable part 13 and the water collecting barrel 8; a pressure rod 15 is fixedly connected to the side of the movable part 13 close to the rotating wheel 10; one end of the pressure rod 15 extending outside the water collecting barrel 8 is rotatably connected to a guide wheel 16, and the guide wheel 16 and the rotating wheel 10 are in contact with each other.

[0051] During the use of the device, the motor inside the control seat 1 can be used to drive the wheel 10 to rotate regularly, so that the guide wheel 16 rolls on the surface of the wheel 10. When the guide wheel 16 contacts the depression between the adjacent protrusions 11, the spring 14 drives the movable part 13 to move toward the wheel 10 in the water collecting tube 8, thereby generating negative pressure inside the water collecting tube 8, and using the collecting pipe 9 to draw the condensed water in the bottom of the jacket 4 into the water collecting tube 8. When the guide wheel 16 contacts the protrusion 11, the guide wheel 16 drives the movable part 13 to move away from the wheel 10 through the pressure rod 15 under the squeezing action of the protrusion 11, and then squeezes the condensed water inside the water collecting tube 8 into the vacuum collector tube 3 through the reflux pipe 12. This structure can improve the collection efficiency of the condensed water inside the jacket 4, and continuously return the collected condensed water to the vacuum collector tube 3, so that it can regenerate water vapor and be used for heating the pipeline 2, thereby realizing water recycling.

[0052] As a preferred embodiment of the present invention, a magnetic plate 17 is provided inside the sleeve 4 at a position corresponding to the rotating wheel 10; an elastic block 18 is fixedly connected between the magnetic plate 17 and the inner wall of the bottom of the sleeve 4; the elastic block 18 is designed to be a hollow structure; a group of conduits 19 are connected to the side of the elastic block 18 away from the control seat 1; the protrusion 11 is made of magnetic material, and the protrusion 11 and the magnetic plate 17 attract each other when they are close to each other. As the wheel 10 drives the protrusions 11 to rotate, when one of the protrusions 11 approaches the magnetic plate 17, the magnetic plate 17 moves toward the protrusion 11 under the action of magnetic attraction and squeezes the elastic block 18. The air inside the elastic block 18 is ejected outward through the conduit 19. When the protrusion 11 is away from the magnetic plate 17, the elastic block 18 automatically expands and recovers, driving the magnetic plate 17 to reset and re-absorb the air into the elastic block 18. The elastic block 18 is used to intermittently blow and inhale air, thereby promoting continuous mixing and exchange of air inside the sheath 4 along the length direction of the pipeline 2, which is beneficial to evenly distribute the heat of water vapor inside the sheath 4, thereby improving the heating uniformity and heating efficiency of the pipeline 2.

[0053] As a preferred embodiment of the present invention, a fixing pin 20 is fixedly connected to the edge of the end face of the rotating wheel 10; a guide ring 21 is rotatably connected to the outer side of the fixing pin 20; a spiral groove 22 is provided on the outer side of the sheath 4, and the part of the sheath 4 located outdoors is provided with a spiral groove 22; an elastic rope 23 is provided inside the spiral groove 22; one end of the elastic rope 23 is fixedly connected to the spiral groove 22, and the other end is fixedly connected to the guide ring 21; a group of balls 24 are evenly distributed on the surface of the elastic rope 23, and the balls 24 protrude from the outer surface of the sheath 4. During the rotation of the wheel 10, the guide ring 21 moves in a circular motion on the surface of the wheel 10, thereby continuously stretching and contracting the elastic rope 23, causing its length to change, thereby driving multiple balls 24 to move inside the spiral groove 22. Since the balls 24 protrude from the outer surface of the sheath 4, if snow or ice accumulates on the surface of the sheath 4 in cold weather, the balls 24 can rub and scrape against the snow and ice on the surface of the sheath 4 during movement, promoting their breakage and falling off, thereby reducing the coverage of ice and snow on the sheath 4, preventing ice and snow from continuously cooling the sheath 4 and the pipeline 2, and ultimately causing the problem of water freezing in the pipeline 2.

[0054] A group of pointed cones 25 are evenly distributed on the surface of the ball 24. By providing the pointed cones 25, when the ball 24 moves inside the spiral groove 22, the friction with the snow layer and the ice layer can be enhanced, and the efficiency of breaking the ice and snow can be improved, which further promotes the ice and snow to fall off the surface of the pipe 2.

[0055] As a preferred embodiment of the present invention, a water-conducting cotton piece 26 is provided on the inner wall of the bottom of the sheath 4 at the position corresponding to the spiral groove 22. The material of the water-conducting cotton piece 26 can be sponge, cotton, cotton cloth, etc.; the two ends of the water-conducting cotton piece 26 respectively cross the spiral groove 22 and are fixedly connected to the inner wall of the sheath 4. Due to the existence of the spiral groove 22, the inner wall of the bottom of the sheath 4 will bulge upward at the corresponding position of the spiral groove 22, which will affect the flow of condensed water. By setting a water-guiding cotton piece 26, the two sides of the raised part of the inner wall of the sheath 4 are connected, and the capillary action of the water-guiding cotton piece 26 is utilized to enable the condensed water to be transmitted inside the water-guiding cotton piece 26. Then, as the condensed water continuously passes through the collecting tube 9 and enters the water collecting cylinder 8, the water level of the condensed water on the side of the bottom of the sheath 4 close to the collecting tube 9 will gradually decrease, so that there is a height difference between the condensed water levels on both sides of the raised part, and then the water-guiding cotton piece 26 can gradually transfer the condensed water on the other side of the raised part to the side close to the collecting tube 9. By setting a water-guiding cotton piece 26 at each raised part of the inner wall of the bottom of the sheath 4, the condensed water in the bottom of the sheath 4 can be prompted to continuously pass over the raised part and flow to the collecting tube 9, thereby further improving the collection efficiency of the condensed water, thereby fully recovering the condensed water.

[0056] like Fig. 9As shown, a method for using a water supply and drainage control device according to the present invention is applicable to the water supply and drainage control device, and comprises the following steps:

[0057] S1: The water inside the vacuum heat collecting tube 3 is heated by solar energy and gradually converted into high-temperature steam. After the steam rises, it enters the hollow structure of the sheath 4 through the gas transmission pipe 5 and heats the pipe 2.

[0058] S2: The motor inside the control seat 1 drives the rotating wheel 10 to rotate regularly. When the guide wheel 16 contacts the depression between the adjacent protrusions 11, the spring 14 drives the movable part 13 to move toward the rotating wheel 10 in the water collecting tube 8, and negative pressure is generated inside the water collecting tube 8. The condensed water in the bottom of the jacket 4 is sucked into the water collecting tube 8 by the collecting pipe 9;

[0059] S3: When the guide wheel 16 contacts the convex block 11, the guide wheel 16 drives the movable part 13 to move away from the rotating wheel 10 through the pressure rod 15 under the extrusion effect of the convex block 11, and squeezes the condensed water inside the water collecting tube 8 into the vacuum heat collecting tube 3 through the return pipe 12;

[0060] S4: During the rotation of the rotating wheel 10, the guide ring 21 moves in a circular motion on the surface of the rotating wheel 10, continuously stretching and contracting the elastic rope 23, so that the length of the elastic rope 23 changes;

[0061] S5: The elastic rope 23 drives the plurality of balls 24 to move inside the spiral groove 22 , and the balls 24 rub and scrape the snow and ice layers on the surface of the sheath 4 , thereby promoting their breaking and falling off, and reducing the coverage of the sheath 4 by ice and snow.

[0062] The above-mentioned front, back, left, right, top and bottom are all based on the figures in the specification. Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
