Description

Technical Field

[0001] This utility model relates to the field of municipal engineering facilities technology, and in particular to a high-efficiency antifreeze device for municipal water supply and drainage pipelines. Background Technology

[0002] In municipal infrastructure construction, water supply and drainage systems are crucial for ensuring the normal operation of cities and the quality of life for residents. However, in cold climates, water supply and drainage pipelines face severe challenges in preventing freezing. Globally, winter temperatures vary significantly across different regions. In high-latitude areas and some high-altitude regions, winter temperatures often remain below freezing for extended periods. For example, in some cities in Northern Europe, average winter temperatures can reach -10°C to -20°C, while in Siberia, Russia, extreme low temperatures can even reach below -50°C. In my country, northern regions such as Northeast and Northwest China also frequently experience extremely cold winters; for instance, the lowest winter temperatures in Harbin can reach around -30°C. This low-temperature environment poses a significant threat to the normal operation of municipal water supply and drainage pipelines.

[0003] When existing technical solutions are used,

[0004] (1) Poor antifreeze effect: Water supply and drainage pipes are difficult to effectively resist extreme cold weather. In a continuous low temperature environment, heat loss is serious and the water temperature in the pipe cannot be maintained above the freezing point, which leads to the water in the pipe freezing and expanding, and then causing problems such as pipe rupture and leakage.

[0005] (2) Insufficient protection at connection points: The connection points of water supply and drainage pipes are usually weak points in terms of frost protection. Existing technologies often neglect the special frost protection requirements of the connection points and fail to design effective protective measures for the structural characteristics of the connection points. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as poor antifreeze performance and insufficient protection of connection points, and to propose a high-efficiency antifreeze device for municipal water supply and drainage pipelines.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a high-efficiency antifreeze device for municipal water supply and drainage pipes, comprising a water supply and drainage pipe, a pipe antifreeze device, a connecting mechanism, and a connection antifreeze device. The pipe antifreeze device is fixedly connected to the outer surface of the water supply and drainage pipe, the connecting mechanism is fixedly connected to one end of the water supply and drainage pipe, and the connection antifreeze device is fixedly connected to the outer surface of the connecting mechanism. The pipe antifreeze device includes a heat insulation layer fixedly connected to the outer surface of the water supply and drainage pipe, a waterproof layer fixedly connected to the outer surface of the heat insulation layer, and a fixing ring sleeved on the outer surface of the waterproof layer.

[0008] Furthermore, connecting plates are fixedly connected to both ends of the fixing ring, and connecting parts are threadedly connected to both sides of the connecting plates.

[0009] Furthermore, the insulation layer and the waterproof layer are fixedly connected to the outer surface of the water supply and drainage pipe, and the fixing ring is fixedly connected to the outer surface of the waterproof layer through a connecting plate.

[0010] Furthermore, the connecting mechanism includes a flange fixedly connected to one end of the water supply and drainage pipe, and limiters are threadedly connected to both sides of the flange. The two water supply and drainage pipes are threadedly connected through the flange and the limiters.

[0011] Furthermore, the antifreeze device at the connection includes a semicircular ring A inserted into the bottom of the water supply and drainage pipe, and a rotating shaft is fixedly connected to the top of the semicircular ring A.

[0012] Furthermore, a semicircular ring B is connected to the outer surface of the rotating shaft, and the semicircular ring A and the semicircular ring B are rotatably connected by the rotating shaft. An antifreeze layer is fixedly connected to the inner wall of the semicircular ring A and the semicircular ring B.

[0013] Furthermore, the two ends of the semicircular ring A and the semicircular ring B are fixedly connected to a fixing plate, and bolts are threadedly connected to both sides of the fixing plate. The semicircular ring A and the semicircular ring B are connected by bolt threads.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, through the synergistic effect of the insulation layer, the waterproof layer, and the fixing ring, the water supply and drainage pipe is provided with multi-layer and all-round protection. The insulation layer can effectively prevent heat from dissipating from the pipe and reduce the drop in water temperature caused by heat loss. The waterproof layer can prevent moisture from penetrating into the insulation layer, ensuring that the insulation layer always stays dry and maintains a good insulation effect. The fixing ring prevents it from shifting on the pipe surface and also enhances the structural stability of the entire pipe antifreeze device, greatly reducing the risk of pipe damage due to freezing.

[0016] 2. In this utility model, by setting up an antifreeze device at the connection point, and by setting up a semi-circular ring structure and an antifreeze layer, the problem of the connection point being susceptible to freezing damage is effectively solved. This ensures that after installation, the connection point of the water supply and drainage pipe can be tightly wrapped, forming a good sealing and heat preservation space, ensuring the safety of the connection point. In cold weather, it can effectively prevent cold air from entering the connection point, maintain the temperature of the connection point, ensure the reliability of the pipe connection, and avoid pipeline system failures caused by freezing damage at the connection point.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a high-efficiency antifreeze device for municipal water supply and drainage pipes, including a water supply and drainage pipe 1, a pipe antifreeze device 2, a connecting mechanism 3, and a connection antifreeze device 4. The pipe antifreeze device 2 is fixedly connected to the outer surface of the water supply and drainage pipe 1, the connecting mechanism 3 is fixedly connected to one end of the water supply and drainage pipe 1, and the connection antifreeze device 4 is fixedly connected to the outer surface of the connecting mechanism 3.

[0025] The following details the specific setup and function of the pipeline antifreeze device 2, the connecting mechanism 3, and the connection antifreeze device 4.

[0026] In this embodiment: the pipe antifreeze device 2 includes a heat insulation layer 21 fixedly connected to the outer surface of the water supply and drainage pipe 1, a waterproof layer 22 fixedly connected to the outer surface of the heat insulation layer 21, and a fixing ring 23 sleeved on the outer surface of the waterproof layer 22.

[0027] The aforementioned components achieve the following effect: they can block external moisture in all directions, preventing rain, snow, or moisture in damp soil from penetrating the insulation layer 21, thus ensuring that it always maintains a good insulation effect.

[0028] Specifically, the two ends of the fixing ring 23 are fixedly connected to the connecting plate 24, and the two sides of the connecting plate 24 are threadedly connected to the connecting piece 25.

[0029] The effect achieved by the above components is to ensure the fixing effect of the retaining ring 23 on the insulation layer 21 and the waterproof layer 22, to prevent displacement, deformation or detachment of the pipe surface, and to ensure that they continuously and stably perform their antifreeze function.

[0030] Specifically, the insulation layer 21 and the waterproof layer 22 are fixedly connected to the outer surface of the water supply and drainage pipe 1, and the fixing ring 23 is fixedly connected to the outer surface of the waterproof layer 22 through the connecting plate 24.

[0031] The effect achieved by the above components is that the tightened fixing ring 23, together with the connecting plate 24 and the connecting piece 25, forms a stable structural frame, further enhancing the overall resistance to external forces of the pipeline antifreeze device 2.

[0032] Specifically, the connecting mechanism 3 includes a flange 31 fixedly connected to one end of the water supply and drainage pipe 1, and limit members 32 are threadedly connected to both sides of the flange 31. The two water supply and drainage pipes 1 are threadedly connected through the flange 31 and the limit members 32.

[0033] The aforementioned components achieve the following effects: the connection structure remains stable, preventing problems such as loose connections or leaks, thus ensuring the sealing and stability of the pipeline system and guaranteeing the normal delivery of water supply and drainage.

[0034] Specifically, the antifreeze device 4 at the connection includes a semi-circular ring A41 inserted into the bottom of the water supply and drainage pipe 1, and a rotating shaft 42 is fixedly connected to the top of the semi-circular ring A41.

[0035] The effect achieved by the above components is that the rotating shaft 42 facilitates subsequent connection and operation. Through the rotating shaft 42, the semi-circular ring B43 can be rotatably connected to it, so that the antifreeze device 4 at the entire connection can be easily opened and closed.

[0036] Specifically, a semicircular ring B43 is connected to the outer surface of the rotating shaft 42. The semicircular ring A41 and the semicircular ring B43 are rotatably connected through the rotating shaft 42. An antifreeze layer 44 is fixedly connected to the inner wall of the semicircular ring A41 and the semicircular ring B43.

[0037] The effect achieved by the above components is as follows: a complete circular structure tightly wraps the connection part of the water supply and drainage pipe 1, and the antifreeze layer 44 can prevent the water at the connection from freezing, avoiding damage to the sealing and stability of the connection part due to the expansion of ice.

[0038] Specifically, the two ends of the semicircular ring A41 and the semicircular ring B43 are fixedly connected to the fixing plate 45, and the two sides of the fixing plate 45 are threadedly connected to the bolts 46. The semicircular ring A41 and the semicircular ring B43 are threadedly connected by the bolts 46.

[0039] The effect achieved by the above components is that bolt 46 can make the two semi-circular rings fit tightly together, forming a good sealing and heat-insulating space.

[0040] Working Principle: In cold winters, when the outside temperature drops below freezing, the pipe antifreeze device 2 first comes into play. The insulation layer 21, with its high-efficiency insulation performance, prevents heat from escaping from the water supply and drainage pipe 1 to the outside, striving to maintain the water temperature inside the pipe above freezing. The waterproof layer 22 constantly resists the intrusion of external moisture, protecting the insulation effect of the insulation layer 21 from being affected. The fixing ring 23 and its related connecting plates 24 and connectors 25 ensure that the entire protective structure is firmly attached to the pipe, unaffected by external forces. For the connection mechanism 3, during the installation and connection of the water supply and drainage pipe 1, the two water supply and drainage pipes 1 are firmly connected together through the threaded connection of the flange 31 and the limiting piece 32, ensuring that... Under normal water pressure and external force, there will be no loosening or leakage at the connection. After the pipe connection is completed, the antifreeze device 4 at the connection will start to function. The construction personnel first place the semi-circular ring A41 at the bottom of the connection of the water supply and drainage pipe 1, and then rotate the semi-circular ring B43 through the rotating shaft 42 to cover the top of the connection. Then, the two semi-circular rings are tightened by the fixing plate 45 and bolts 46, tightly wrapping the connection. In low temperature environment, the antifreeze layer 44 lowers the freezing point of the connection and prevents water from freezing. At the same time, the sealed structure effectively prevents cold air from entering, maintains the temperature of the connection, ensures the safety and stability of the pipe connection under cold conditions, and ensures the normal operation of the entire municipal water supply and drainage system.
