Description

Technical Field

[0001] This utility model relates to the field of pipeline antifreeze technology, specifically an antifreeze device for pipelines in rural water supply projects. Background Technology

[0002] In rural water supply processes, the water pipes are exposed above the ground. When farmland, vegetable gardens, or orchards need water, they can simply turn on the tap to get water. However, in winter, because the water pipes are exposed to the air, the low temperature can cause the water inside the pipes to freeze, resulting in the pipes freezing and water not being able to flow.

[0003] Currently, the antifreeze devices are made by wrapping a layer of sponge around the outside of the water pipe and tying the sponge to the outside of the water pipe with ropes to keep it warm and prevent freezing. However, the antifreeze effect is not obvious when the temperature is extremely low, and the pipe is still easy to freeze. Hot water needs to be poured to thaw it. The antifreeze effect cannot be adjusted according to the temperature change, so its practicality is low.

[0004] Therefore, this utility model provides an antifreeze device for rural water supply pipelines to solve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved This utility model provides an antifreeze device for rural water supply pipelines, aiming to solve the problems mentioned in the background art.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: It includes a pipe body, with a detachable outer casing fitted over the pipe body, and a fixed frame fixedly connected to the top of the outer casing; an antifreeze component, comprising an annular pipe embedded inside the outer casing, with an outlet pipe and a return pipe fixedly connected to both ends of the annular pipe respectively, and a telescopic pipe fixedly connected to the top of the return pipe; an electric hot water tank fixedly connected to the outside of the telescopic pipe and the return pipe; a pump body installed at the connection between the outlet pipe and the annular pipe; and a trigger component installed inside the fixed frame. During use, the trigger component can detect the ambient air temperature in real time. When the temperature drops below three degrees Celsius, a closed circuit is automatically formed, further activating the antifreeze component. Through the antifreeze component, heat exchange and heating of the pipe body are achieved, achieving an antifreeze effect. No manual intervention is required during the process; it is automatic. The anti-freeze mode activates based on temperature changes, offering high flexibility and energy savings. When the ambient temperature drops to approximately three degrees Celsius below freezing, the ethanol gas inside the telescopic corrugated tube bladder contracts, causing the bladder to shrink and the sliding plate to slide downwards within the fixed frame. This moves the positive electrode closer to the negative electrode, forming a closed circuit. Simultaneously, the pump and electric water tank begin operation. The pump draws hot water from the outlet pipe into the annular tube, then returns through the return pipe and telescopic tube back into the water tank. This continuous flow of hot water into the annular tube enhances heat exchange and temperature control, further preventing freezing. When the temperature rises, the telescopic corrugated tube bladder expands, the positive electrode moves away from the negative electrode, the circuit breaks, and the anti-freeze component stops operating. This flexible and convenient activation is based on actual needs.

[0007] As a preferred technical solution of this application, the outer casing is fixedly connected to two mounting plates, and the two mounting plates are internally threaded with multiple locking bolts. By combining the mounting plates and locking bolts, the casing can be locked after being fitted onto the outside of the pipe body.

[0008] As a preferred technical solution of this application, the inner wall of the casing is fitted with thermal insulation cotton, which can play the role of heat preservation and antifreeze.

[0009] As a preferred technical solution of this application, the triggering component includes multiple sliding rods, each of which is fixedly connected to the top interior of the fixed frame. Each of the multiple sliding rods is fitted with a sleeve, and a sliding plate is fixedly connected to the bottom of the sleeve. A telescopic corrugated air bladder is fixedly connected to the bottom of the sliding plate, and a positive electrode plate is fixedly connected to the bottom of the sliding plate. A negative electrode plate is fixedly connected to the bottom interior of the fixed frame. The telescopic corrugated air bladder is filled with a specific proportion of ethanol gas, which can contract or expand with changes in temperature, and can simultaneously control the positive electrode plate to move closer to or further away from the negative electrode plate.

[0010] As a preferred technical solution of this application, a return spring is provided inside the sleeve. The return spring is fixedly connected to the bottom of the slide rod. Through the elastic force of the return spring, it can act in the opposite direction on the slide plate, which can further make the slide plate continue to move downward.

[0011] As a preferred technical solution of this application, the positive electrode, the negative electrode, the pump body, and the electric water tank are all in the same closed circuit. The positive electrode and the negative electrode are located on the same vertical plane. By moving the positive electrode closer to the negative electrode, a closed circuit is formed, which allows the electric water tank and the pump body to start operating.

[0012] As a preferred technical solution of this application, multiple ventilation holes are provided on both sides of the fixed frame, which facilitates the telescopic corrugated airbag to detect the current ambient temperature in real time.

[0013] (III) Beneficial Effects During use, the trigger component can detect the ambient air temperature in real time. When the temperature is below three degrees Celsius, a closed circuit will be automatically formed, which will further activate the antifreeze component. The antifreeze component can achieve heat exchange and temperature rise of the tube body, thus achieving the antifreeze effect. No manual intervention is required during the process. The antifreeze mode can be automatically activated according to the temperature change, which is highly flexible and can be activated simultaneously to save energy according to actual needs.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model provides a freeze protection device for rural water supply pipelines, such as... Figure 1-4As shown, this type of antifreeze device for rural water supply pipelines includes: a pipe body 1, with a detachable casing 2 fitted over the pipe body 1, and a fixing frame 5 fixedly connected to the top of the casing 2; an antifreeze component, including an annular pipe 19, which is embedded inside the casing 2, with an outlet pipe 7 and a return pipe 9 fixedly connected to both ends of the annular pipe 19 respectively, and a telescopic pipe 8 fixedly connected to the top of the return pipe 9. An electric hot water tank 6 is fixedly connected to the outside of the telescopic pipe 8 and the return pipe 9. A pump body 11 is installed at the connection between the outlet pipe 7 and the annular pipe 19. A triggering component is installed inside the fixing frame 5. During use, the triggering component can detect the ambient air temperature in real time. When the temperature drops below three degrees Celsius, a closed circuit is automatically formed, further activating the antifreeze component. Through the antifreeze component, heat exchange and heating of the pipe body 1 are achieved, achieving the antifreeze effect. No manual intervention is required during the process; the antifreeze mode can be automatically activated according to temperature changes, providing flexibility. It is highly efficient and can be activated synchronously according to actual needs, saving energy. When the ambient temperature drops to around three degrees below freezing, the ethanol gas inside the telescopic corrugated air bladder 16 contracts, causing the telescopic corrugated air bladder 16 to contract synchronously. This causes the sliding plate 15 to slide downward inside the fixed frame 5, further allowing the positive electrode 17 to move closer to the negative electrode 18, forming a closed circuit. This simultaneously starts the pump body 11 and the electric water tank 6 to operate. The pump body 11 draws hot water from the outlet pipe 7 into the annular pipe 19, and finally flows out from the return pipe 9 through the telescopic pipe 8 back into the electric water tank 6. This allows hot water to continuously enter the annular pipe 19, achieving heat exchange and heating of the outside of the pipe body 1, further serving the purpose of antifreeze. When the temperature rises, the telescopic corrugated air bladder 16 expands, the positive electrode 17 moves away from the negative electrode 18, the circuit is broken, and the antifreeze component stops operating. It can be activated according to actual needs, making it more flexible and convenient.

[0018] The outer casing 2 is fixedly connected to two mounting plates 3. The two mounting plates 3 are internally threaded with multiple locking bolts 4. By combining the mounting plates 3 and the locking bolts 4, the casing 2 can be locked after being fitted onto the outside of the pipe body 1. The inner wall of the casing 2 is fitted with thermal insulation cotton 20, which can play a role in heat preservation and antifreeze.

[0019] The triggering assembly includes multiple sliding rods 13, all of which are fixedly connected to the top of the fixed frame 5. Each sliding rod 13 is fitted with a sleeve 12. A sliding plate 15 is fixedly connected to the bottom of the sleeve 12. A telescopic corrugated air bladder 16 is fixedly connected to the bottom of the sliding plate 15. A positive electrode 17 is fixedly connected to the bottom of the sliding plate 15. A negative electrode 18 is fixedly connected to the bottom of the fixed frame 5. The telescopic corrugated air bladder 16 is filled with a specific proportion of ethanol gas. The specific proportion of ethanol gas can contract or expand with changes in temperature, and can synchronously control the positive electrode 17 to move closer to or further away from the negative electrode 18. A return spring 14 is fitted inside the sleeve 12. The return spring 14 is fixedly connected to the bottom of the sliding rod 13. The elastic force of the return spring 14 can act in the opposite direction on the sliding plate 15, which can further make the sliding plate 15 continue to move downward.

[0020] The positive electrode 17, negative electrode 18, pump body 11, and electric water tank 6 are all in the same closed circuit. The positive electrode 17 and negative electrode 18 are located on the same vertical plane. By moving the positive electrode 17 closer to the negative electrode 18, a closed circuit is formed, which allows the electric water tank 6 and pump body 11 to start operation. Multiple vent holes 10 are provided on both sides of the fixed frame 5. The vent holes 10 can facilitate the telescopic corrugated airbag 16 to detect the current ambient temperature in real time.

[0021] When this type of antifreeze device for rural water supply pipelines is in use, when the ambient temperature drops to around three degrees Celsius near freezing, the ethanol gas inside the telescopic corrugated pipe air bladder 16 contracts, causing the air bladder 16 to contract simultaneously. This causes the sliding plate 15 to slide downwards inside the fixed frame 5, further allowing the positive electrode 17 to move closer to the negative electrode 18, forming a closed circuit. Simultaneously, the pump body 11 and the electric hot water tank 6 begin operation. The pump body 11 draws hot water from the outlet pipe 7 into the annular pipe 19, and finally flows out from the return pipe 9 through the telescopic pipe 8 back into the electric hot water tank 6. This allows hot water to continuously enter the annular pipe 19, achieving heat exchange and temperature rise on the outside of the pipe body 1, further achieving the antifreeze purpose. When the temperature rises, the telescopic corrugated pipe air bladder 16 expands, the positive electrode 17 moves away from the negative electrode 18, the circuit is broken, and the antifreeze component stops operating. It can be activated according to actual needs, making it more flexible and convenient.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
