Description

Technical Field

[0001] This utility model relates to the field of water supply and drainage pipeline technology, and in particular to an antifreeze water supply and drainage pipeline for water conservancy projects. Background Technology

[0002] Water supply and drainage pipelines are an important component of water conservancy projects. Especially in cold regions or areas with large seasonal temperature variations, the antifreeze properties of pipelines have always been a key technical challenge that needs to be considered in design and construction. Traditional water supply and drainage pipelines are prone to freezing in low-temperature environments, leading to problems such as pipeline rupture and leakage, which seriously affect the normal operation of water conservancy projects. Therefore, an antifreeze water supply and drainage pipeline for water conservancy projects is proposed.

[0003] There are already various antifreeze pipe materials and technologies on the market, but these technologies have certain limitations. They have poor insulation effects, so when the external environment is cold, the pipe walls may still freeze and crack. At the same time, the existing water supply and drainage pipes are not strong enough to withstand the pressure of external heavy objects. When subjected to pressure from external objects, the pipes are very easy to break, resulting in water leakage.

[0004] Therefore, those skilled in the art have provided an antifreeze water supply and drainage pipeline for hydraulic engineering to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an antifreeze water supply and drainage pipeline for water conservancy projects. Through the installation of a spiral arc plate, the water flow is extended along the inner wall of the drainage pipe. This increases the friction distance between the water flow and the pipe, generating heat through a heat-generating effect. External insulation cotton then insulates the drainage pipe, preventing it from freezing and cracking due to external environmental conditions.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A frost-resistant water supply and drainage pipeline for water conservancy projects includes an insulation component. The insulation component houses a drainage pipe with multiple spiral arc plates fixedly connected to its inner wall. The outer wall of the drainage pipe is provided with insulation cotton, silicone pads, and multiple support columns. The insulation cotton is spaced out over the outer wall of the drainage pipe, and the silicone pads are fixed to the front and rear outer walls of the insulation cotton. The multiple support columns are arrayed and fixed to the outer wall of the drainage pipe. The insulation component includes a polyethylene pipe fixedly connected to the outer wall of the multiple support columns on the side away from the drainage pipe. The outer wall of the polyethylene pipe is covered and fixedly covered with glass fiber cotton, and the side of the glass fiber cotton away from the polyethylene pipe is covered and fixedly covered with stainless steel sheet. Through the above technical solutions and innovative composite structure design, the pipeline can maintain its temperature for a long time in cold climates, preventing the water from freezing.

[0007] Furthermore, the glass fiber cotton has placement holes formed by compressing the thickness of the glass fiber cotton inside; The above technical solution provides physical space and convenient conditions for the subsequent installation of active heating elements through the placement holes set inside the glass fiber cotton.

[0008] Furthermore, the inner wall of the silicone pad is fixedly connected to the outer wall of the drainage pipe, and the outer wall of the silicone pad is fixedly connected to the inner wall of the polyethylene pipe. The above technical solution tightly integrates the drainage pipe and the insulation structure into a whole, enhancing the overall rigidity and stability of the pipeline and reducing the loosening and wear of internal components.

[0009] Furthermore, the outer wall of the insulation cotton is provided with multiple through holes, and the outer wall of the support column is in close contact with the inner wall of the through holes; The above technical solution allows for easier fixing of the support column to the drainage pipe and polyethylene pipe through the through holes, while effectively ensuring the insulation effect of the insulation cotton.

[0010] Furthermore, the spiral arc plate is made of copper or aluminum; The above technical solution allows copper and aluminum materials to effectively absorb more heat, thereby raising the temperature of the drainage pipe.

[0011] Furthermore, the glass fiber cotton is fixed to the outer wall of the polyethylene pipe by binding and adhesive. The above technical solution involves using stainless steel cable ties or wires for binding, and then using a special adhesive for polyethylene to coat the outer wall of the polyethylene pipe. This, combined with the stainless steel cable ties or wires, wraps the glass fiber cotton around the outer wall of the polyethylene pipe, preventing it from coming off due to insecure fixing and ensuring the stability of the long-term insulation effect.

[0012] This utility model has the following beneficial effects: 1. This utility model proposes an antifreeze water supply and drainage pipeline for water conservancy projects. The insulation component consists of a multi-layer composite insulation structure composed of polyethylene pipe, glass fiber cotton and stainless steel sheet from the inside out. This effectively blocks the loss of internal heat to the outside and prevents the intrusion of external low temperature, thereby significantly improving the overall antifreeze performance of the pipeline. The evenly distributed support columns form a stable support system between the drainage pipe and the external insulation component. This not only enhances the pressure resistance of the pipeline against external extrusion and avoids stress concentration leading to cracking, but also ensures that the insulation layer and the pipeline maintain a constant gap, further optimizing the insulation effect.

[0013] 2. The present invention proposes an antifreeze water supply and drainage pipeline for water conservancy projects. By setting a spiral arc plate, when the water flows through the spiral arc plate on the inner wall of the drainage pipe, the distance of the water flow is extended, thereby increasing the friction distance between the water flow and the pipe. This generates heat through a heat generation effect, so that the pipe and the water flow are both insulated by the external insulation cotton, thus preventing the pipe from freezing and cracking due to the external environment.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] One specific embodiment of this utility model is provided: Reference Figure 1 , Figure 2 and Figure 5 : A water supply and drainage pipeline for water conservancy projects is provided, including an insulation component 1. The insulation component 1 is provided with a drainage pipe 3. Multiple spiral arc plates 2 are fixedly connected to the inner wall of the drainage pipe 3. The outer wall of the drainage pipe 3 is provided with insulation cotton 5, silicone pads 6 and multiple support columns 7. The insulation cotton 5 is wrapped around the outer wall of the drainage pipe 3 in an intermittent manner. The silicone pads 6 are fixed to the front and rear outer walls of the insulation cotton 5. The multiple support columns 7 are fixed in an array on the outer wall of the drainage pipe 3. The insulation component 1 includes a polyethylene pipe 101 fixedly connected to the outer wall of the multiple support columns 7 away from the drainage pipe 3. The outer wall of the polyethylene pipe 101 is covered and fixed with glass fiber cotton 102. The side of the glass fiber cotton 102 away from the polyethylene pipe 101 is covered and fixed with stainless steel sheet 103. Through innovative composite structure design, the pipeline can maintain its temperature for a long time in cold climates, preventing the water from freezing.

[0019] Reference Figure 2 , Figure 3 and Figure 6 : The glass fiber cotton 102 has placement holes 104 formed by compressing its thickness. These holes provide physical space and convenience for the subsequent installation of active heating elements. The inner wall of the silicone pad 6 is fixedly connected to the outer wall of the drainage pipe 3, and the outer wall of the silicone pad 6 is fixedly connected to the inner wall of the polyethylene pipe 101. This tightly integrates the drainage pipe 3 with the insulation structure, enhancing the overall rigidity and stability of the pipeline and reducing loosening and wear of internal components. The outer wall of the insulation cotton 5 has multiple through holes 4, and the outer walls of the support columns 7 are tightly fitted to the inner walls of the through holes 4. The through holes 4 facilitate the fixing of the support columns 7 to the drainage pipe 3 and the polyethylene pipe 101, effectively ensuring the insulation effect of the insulation cotton 5. Reference Figure 4 and Figure 6 : The spiral arc plate 2 is made of copper or aluminum. Copper and aluminum materials can effectively absorb more heat, thereby raising the temperature of the drainage pipe 3. The glass fiber cotton 102 is fixed to the outer wall of the polyethylene pipe 101 by binding and adhesive. It is bound with stainless steel cable ties or iron wire, and then a special adhesive for polyethylene is applied to the outer wall of the polyethylene pipe 101. The glass fiber cotton 102 is wrapped around the outer wall of the polyethylene pipe 101 with stainless steel cable ties or iron wire, preventing it from falling off due to insecure fixation, and ensuring the stability of long-term heat preservation effect.

[0020] Working principle: During daily use, some water flows through the spiral arc plate 2, causing it to spiral along the inner wall of the drainage pipe 3. This increases the flow distance of the water within the drainage pipe 3, generating friction and heat through friction, thus raising the temperature of both the water and the pipe. The increased friction distance within the same section of the drainage pipe 3 further increases the heat generated by the water flow. The outer insulation cotton 5 prevents heat loss from the drainage pipe 3, thus providing insulation. The insulation component 1, with stainless steel sheet 103 securing the glass fiber cotton 102, further enhances the insulation. The glass fiber cotton 102 is fixed to the outer wall of the polyethylene pipe 101, thus providing both anti-fouling protection and insulation for the polyethylene pipe 101. This secondary insulation prevents the temperature of the drainage pipe 3 from leaking out. The multiple support columns 7 effectively support the polyethylene pipe 101 and the drainage pipe 3, thereby distributing the external pressure and preventing damage to the drainage pipe 3 due to pressure concentration. The placement hole 104 allows the user to insert an electric heating wire into the insulation component 1 as needed, thereby heating the polyethylene pipe 101 and preventing external temperature intrusion that could cause the drainage pipe 3 to freeze and crack.
