Description

Technical Field

[0001] This utility model relates to the field of pipeline protection technology, and in particular to a protective device for drainage pipelines. Background Technology

[0002] Drainage pipes include sewage pipes, wastewater pipes, rainwater pipes, and tap water pipes. Existing drainage pipes are typically made of materials such as galvanized iron pipes, copper pipes, stainless steel pipes, and aluminum-plastic composite pipes. In recent years, with the improvement of residents' living standards, water consumption has been increasing, and to meet water demand, the diameter of residential drainage pipes is also increasing. Some drainage pipes require exposed installation. Because the water supply pipes are directly exposed to the air, when passing through areas with high humidity and encountering the lower temperature of the drainage pipes, the local air temperature is lowered, causing condensation to form on the outside of the pipes.

[0003] Condensation accelerates the corrosion of metal drainage pipes, reduces their lifespan, causes leaks, and easily pollutes and damages the environment of the area where the drainage pipes are located. Current traditional drainage pipe protection structures involve covering the outer wall of the pipe with a protective layer and then securing it with tape. This type of protection structure has low strength, short service life, and unsatisfactory protective effect. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a protective device for drainage pipes, which is simple to operate, has high fixing strength, better protective effect, and can improve the protection of pipes and extend the service life of pipes.

[0005] This utility model is achieved using the following technical solution: a protective device for a drainage pipe, comprising a protective shell that wraps around the outer ring of the pipe; fastening rings, wherein multiple fastening rings are equally spaced and sleeved on the outside of the protective shell to tightly fix the protective shell to the outer wall of the pipe; connecting ears, wherein each fastening ring has several connecting ears symmetrically arranged at both ends; and a connector, wherein the connector connects the connecting ears at both ends of each fastening ring, and the tightness of the connector can be adjusted.

[0006] Furthermore, the protective shell includes an adhesive layer disposed on the innermost side; a waterproof layer covering the outer side of the adhesive layer; an outer protective layer disposed on the outermost side; and an insulation layer disposed between the waterproof layer and the outer protective layer.

[0007] Furthermore, the protective shell also includes a rock wool protective layer, which is disposed between the insulation layer and the outer protective layer.

[0008] Furthermore, the connecting element is a tie wire.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. The protective device for drainage pipes of this utility model can adjust the tightness of each fastening ring by adjusting the binding length of the binding wire, so that the fastening rings can tightly fix the protective shell to the outer wall of the pipe. It is simple to operate, has high fixing strength, and better protective effect.

[0011] 2. The drainage pipe protective device of this utility model, through the setting of an adhesive layer, a waterproof layer, a heat insulation layer, a rock wool protective layer and an external protective layer, makes the anti-condensation effect of the protective shell better, the adhesion of the protective shell stronger, effectively reduces condensation, improves the protection of the pipe, and extends the service life of the pipe.

[0016] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0017] The purpose of this invention is to provide a protective device for drainage pipes, addressing the shortcomings of existing technologies.

[0018] Example 1

[0019] This embodiment provides a protective device for drainage pipes, referring to... Figure 1 , Figure 2As shown, the device includes a protective shell 2, fastening rings 3, connecting ears 4, and connectors. The protective shell 2 wraps around the outer ring of the pipe 1. Multiple fastening rings 3 are evenly spaced and fitted around the outside of the protective shell 2, tightly fixing the protective shell 2 to the outer wall of the pipe 1. Each fastening ring 3 has three connecting ears 4 symmetrically arranged at both ends. The connectors connect the two ends of the connecting ears 4 of each fastening ring 3. The tightness of the connectors can be adjusted. In this embodiment, the connectors use tie wires 5, which are tied to two corresponding connecting ears 4. By adjusting the binding length of the tie wires 5, the tightness of each fastening ring 3 can be adjusted, so that the fastening rings 3 tightly fix the protective shell 2 to the outer wall of the pipe 1. This invention is simple to operate, has high fixing strength, and provides better protection.

[0020] Reference Figure 3 As shown, the protective shell 2 includes an adhesive layer 21, a waterproof layer 22, an insulation layer 23, a rock wool protective layer 24, and an outer protective layer 25. The adhesive layer 21 is located on the innermost side. In this embodiment, the adhesive layer 21 uses a non-asphalt self-adhesive layer from the prior art, with a thickness of 0.3-0.5 mm. It can be adhered to the outer wall of the pipe 1, improving the adhesion of the protective shell 2 and making its installation more convenient and the fixing effect better. The waterproof layer 22 covers the outside of the adhesive layer 21. In this embodiment, the waterproof layer 22 uses a polyethylene geomembrane root-penetration resistant waterproof layer from the prior art, with a thickness of 0.5-1 mm. It has excellent flexibility, a high impermeability coefficient, heat resistance, and cold resistance. Its operating temperature range is 110℃ (high temperature) and -70℃ (low temperature), which significantly improves the material's construction performance and provides strong weather resistance. It can effectively prevent external moisture from entering and contacting the outer wall of the pipe 1, thereby effectively preventing corrosion. The outer protective layer 25 is located on the outermost side. In this embodiment, the outer protective layer 25 uses PVC flexible board with a thickness of 2-5mm. It is cold-resistant, wear-resistant, corrosion-resistant, and has excellent tear resistance. The thermal insulation layer 23 is located outside the waterproof layer 22. The thermal insulation layer 23 uses thermal insulation cotton layer in the prior art, which has high strength, oxidation resistance, and corrosion resistance, and has heat insulation and heat preservation properties, effectively preventing condensation and water droplets. The rock wool protective layer 24 is located between the thermal insulation layer 23 and the outer protective layer 25. The rock wool protective layer 24 uses rock wool board in the prior art, which has the characteristics of heat insulation, fire resistance, and sound absorption.

[0021] This utility model discloses a protective device for drainage pipes. The protective shell 2 has strong adhesion and is easy to install. By cooperating with the fastening ring 3 and the binding wire 5, it is convenient to carry out construction and installation, and can effectively improve the fixing strength. Through the setting of the waterproof layer 22, the heat insulation layer 23, the rock wool protective layer 24 and the external protective layer 25, the anti-condensation effect of the protective shell 2 is better, which can effectively reduce condensation, protect the pipe, improve the protection of the pipe, and extend the service life of the pipe.
