Abstract
Description
Technical Field
[0001] This utility model relates to the field of water supply equipment technology, specifically to an outdoor antifreeze integrated water supply equipment with self-heating function. Background Technology
[0002] In winter, water in outdoor pipes and those in permafrost areas freezes when not flowing, easily leading to pipe cracking. For drinking water pipes, insulation is typically achieved by wrapping foam or cloth around the pipes. However, after a period of use, the foam and cloth on the outer wall of the pipes fail in low temperatures, losing their insulating effect. Furthermore, the thawing time actually increases after the external insulation layer fails, making the system less reliable. Therefore, we propose an outdoor, freeze-resistant, integrated water supply system with self-heating capabilities. Utility Model Content

[0004] To address the aforementioned shortcomings of existing technologies, this utility model provides an outdoor antifreeze integrated water supply device with self-heating function. This device effectively solves the problem that existing pipes are typically insulated by wrapping foam or cloth strips around them. However, after a period of use, the foam or cloth strips on the outer wall of the pipe will fail in low-temperature environments and will no longer provide insulation. Furthermore, when the external insulation layer fails, the thawing time actually increases, resulting in relatively inconsistent performance.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0032] The present invention will be further described below with reference to the embodiments.
[0033] Example: Refer to Appendix Figure 1-6As shown, an outdoor antifreeze integrated water supply device with self-heating function includes a pipe fitting 100 and sleeves 200 sleeved at both ends of the pipe fitting 100, forming an annular groove 201 between the sleeves 200 and the outer wall of the pipe fitting 100; a semiconductor ring 400 sleeved on the outer wall of the pipe fitting 100 and located in the annular groove 201; and a circular ring 500 sleeved on the outer wall of the pipe fitting 100 and located on one side of the semiconductor ring 400, with an annular bladder 510 provided inside the circular ring 500, the annular bladder 510 being filled with an expansion material, and symmetrically arranged bending plates 520 on the inner wall of the circular ring 500. When the annular bladder 510 expands and squeezes the bending plates 520, the two bending plates 520 in symmetrical positions change from an overlapping state to a non-overlapping state, at which time the semiconductor ring 400 is de-energized.
[0034] Specifically, the water supply equipment mentioned in this application mainly includes pipe fittings 100, which are used for water transportation and are exposed to the external environment. At both ends of the pipe fitting 100, sleeves 200 are provided. The pipe fitting 100 is a common PC pipe. A semiconductor ring 400 is provided inside the sleeve 200 and on the outer wall of the pipe fitting 100. The purpose of this design is that when the external ambient temperature is low, the temperature of the pipe fitting 100 is also low, and the cold end of the semiconductor ring 400 is close to the outer wall of the pipe fitting 100. In the process of wall contact, the hot end of the semiconductor ring 400 contacts the annular groove 201. When the semiconductor ring 400 is working, it heats the air inside the annular groove 201. It also includes a rubber ring 300 sleeved on the outer wall of the tube 100, and a cavity formed between the rubber ring 300 and the outer wall of the tube 100. The cavity is in communication with the annular groove 201. In actual use, when the semiconductor ring 400 is running, the heated air will heat the tube 100 in the cavity, thereby effectively preventing the water inside the tube 100 from freezing and ensuring normal water supply.
[0035] Specifically, in this application, the cold end of the semiconductor ring 400 is attached to the outer wall of the tube 100, while the hot end of the semiconductor ring 400 is located on the outer side and exposed in the annular groove 201. Correspondingly, when the semiconductor ring 400 is in operation, especially when used in a low-temperature environment, the temperature of the water remaining in the tube 100 will also decrease. Through conduction through the inner wall of the tube 100, the temperature of the cold end of the semiconductor ring 400 is low. Utilizing the Peltier effect, the temperature of the hot end of the semiconductor ring 400 will increase, thereby heating the gas in the annular groove 201. During this process, the heated gas will enter the chamber and heat the tube 100 as a whole.
[0036] Correspondingly, a permeable membrane 210, uniformly arranged in a ring shape on the inner wall of the sleeve 200, is also included. External air can enter the interior of the annular groove 201 through the permeable membrane 210 and be heated by the semiconductor ring 400 in operation. The purpose of the permeable membrane 210 is to prevent water from the external environment from directly entering the annular groove 201 and affecting the performance of the semiconductor ring 400.
[0037] In this application, to improve automation and avoid wasting energy due to the semiconductor ring 400 being in operation for extended periods, the application also includes adaptively opening or closing the semiconductor ring 400 based on the temperature of the tube 100. Specifically, the semiconductor ring 400 is electrically connected to an external power source via a wire 410. When the two bending plates 520 are not in contact, the semiconductor ring 400 is disconnected from the external power source. The application also includes a mounting groove 501 located in the middle of the ring 500, with an annular bladder 510 disposed within the mounting groove 501. A heat-conducting ring is provided on the inner wall of the ring 500, overlapping with the outer wall of the tube 100. A mounting ring 120 is located on one side of the ring 500 and is fixedly connected to the outer wall of the tube 100.
[0038] Specifically, when the external ambient temperature is low, the expansion material within the annular bladder 510 expands in volume as the external temperature rises and remains in its basic shape or shrinks when the external temperature is low. In this application, this property of the expansion material is used to control the operating state of the semiconductor ring 400. Specifically, when the external temperature is low, the expansion material within the annular bladder 510 is in its basic state, and the ends of the bent plates 520 on both sides of the mounting groove 501 are in an overlapping state. (Refer to the attached diagram.) Figure 5 As shown in the overlapping state of the two bent plates 520, when the temperature rises, the corresponding expansion material will cause the annular bladder 510 to expand synchronously. The outer wall of the expanded annular bladder 510 will separate from the bent plates 520, causing the bent plates 520 to change from a contact state to a separated state. As one implementation method, the bent plates 520 mentioned in this application are made of metal with a thin wall thickness and can be made of metal with good elasticity. When the ends of the two bent plates 520 are not in contact, the semiconductor ring 400 is disconnected from the external power supply. At this time, the external temperature is high, and there is no need to consider the problem of water freezing inside the tube 100. When the temperature drops again, the corresponding expansion material recovers, and the bent plates 520 will also recover and re-overlap. The semiconductor ring 400 is in operation and heats the tube 100. Automatic control is achieved in this way.
[0039] Furthermore, in low-temperature environments, to prevent the pipe fitting 100 from not heating up in time, this application also includes multiple through slots formed on the semiconductor ring 400. A rigid plate 110 is provided on the outer wall of the pipe fitting 100 at the position of the through slot, and the rigid plate 110 is connected and fixed to the inner wall of the sleeve 200 by an energized spring 130. When the two bending plates 520 are not in contact, the energized spring 130 extends and returns to its original position. In low-temperature environments, when the expanded material returns to its original position, the corresponding bending plates 520 come into contact. At this point, the corresponding energized spring 130 changes from a non-energized state to an energized state. At this time, the energized spring 130 will contract, while the position of the sleeve 200 is fixed. The corresponding rigid plate 110 will drive the pipe fitting 100 to vibrate. In this way, the fluidity of the water in the pipe fitting 100 is increased, reducing the possibility of freezing. Subsequently, as the semiconductor ring 400 operates, the pipe fitting 100 is gradually heated and begins to heat up, effectively preventing freezing.
[0040] In actual use, the length of the rubber ring 300 is set according to actual needs, and the two ends of the rubber ring 300 are respectively connected and fixed to the outer walls of the two sleeves 200. The outer wall of the rubber ring 300 has multiple through holes 301 in a ring structure. The through holes 301 and the breathable membrane 210 serve as channels for gas flow, which can increase the flow of gas inside the chamber and the annular groove 201. When the semiconductor ring 400 is running, it can ensure that the hot air covers the outer wall of the tube 100 more comprehensively, thereby achieving efficient heating.
[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
