Description

Technical Field

[0001] The utility model relates to the technical field of water supply and drainage pipelines, in particular to a water supply and drainage pipeline protection structure. Background Art

[0002] In modern urban infrastructure, water supply and drainage pipes play a vital role. They are like the blood vessels of a city, ensuring the supply of clean water, the safe discharge of waste and excess water, and the smooth progress of residents' daily life and industrial production. These pipeline networks are not only buried deep underground and hidden under the foundation of buildings, but also partially exposed in conspicuous locations such as walls and ceilings. Therefore, they frequently interact with the external environment and are subjected to multiple tests such as physical damage, natural corrosion and accidental damage. In view of the fragility of water supply and drainage pipes and their importance to public health and environmental protection, a comprehensive pipeline protection strategy is currently being implemented.

[0003] For example, Chinese patent CN219177208U discloses a water supply and drainage pipe protection structure, including a first protective plate, a second protective plate, a connecting plate, a support adjustment mechanism and a connecting mechanism; the filling inlet is used to inflate the interior of the filling airbag component to achieve filling of the second protective plate and the first protective plate, thereby ensuring the stability of the water supply and drainage pipe protection, so that the second protective plate and the first protective plate can fully fit the water supply and drainage pipe. However, when the above-mentioned protection structure uses airbag components to ensure the stability of the water supply and drainage pipe, the airbag components are not interconnected, which results in the airbag components being unable to construct an overall buffer network to evenly disperse the load on the pipe, resulting in pressure concentration at a single location, which is not conducive to more evenly supporting the pipe, and is particularly unsuitable for pipe support in complex stress environments.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0005] In view of the problems in the related technology, the utility model proposes a water supply and drainage pipe protection structure to overcome the above technical problems existing in the existing related technology.

[0006] To this end, the specific technical solutions adopted by the utility model are as follows:

[0007] A water supply and drainage pipe protection structure is sleeved on the outer side of the circumference of the water supply and drainage pipe, including a sound insulation layer installed on the outer side of the water supply and drainage pipe, a buffer layer is sleeved on the outer side of the sound insulation layer, and a protective shell is sleeved on the outer side of the buffer layer. End caps are arranged at both ends of the protective shell, and the inner sides of the end caps are connected to the sound insulation layer and the buffer layer.

[0008] Furthermore, in order to soundproof and insulate the water supply and drainage pipes, a closed air cavity can be formed under the cooperation of panel one, honeycomb core and panel two. When sound waves pass through these air cavities, they will be reflected on the cavity wall and produce multiple reflections and interferences, causing the sound energy to gradually be converted into heat energy and dissipated, thereby weakening the penetration of the sound waves and achieving a sound insulation effect; and because air is a poor conductor of heat, a large number of closed air cavities form a very good thermal insulation barrier, which effectively slows down the conduction of heat energy and achieves a significant barrier to the transfer of heat energy, thereby achieving an excellent insulation effect. The sound insulation layer includes panel one which is sleeved on the outside of the water supply and drainage pipe, and a plurality of honeycomb cores are arranged on the outside of panel one, and panel two is arranged on the side of the honeycomb core away from the water supply and drainage pipe; the cross-section of the honeycomb core is a regular hexagonal structure, and two adjacent groups of honeycomb cores share a common side.

[0009] Furthermore, in order to evenly disperse the load on the pipeline and thus support the pipeline more evenly, the connecting air pipe can connect the air bags so that all the air bags can be constructed into an integrated buffer network, thereby achieving balanced distribution of the pressure on the pipeline in the entire buffer network and avoiding pressure concentration at a single position on the pipeline. The buffer layer includes a plurality of air bags mounted on the outside of the sound insulation layer, and two adjacent groups of air bags are connected by a connecting air pipe; a support plate is provided on the side of the air bag away from the water supply and drainage pipe; and the plurality of air bags are evenly arranged and distributed in a rectangular shape on one side of the support plate.

[0010] Furthermore, in order to ensure that the overall protection structure can remain stable after multiple water supply and drainage pipes are connected, the two groups of saw teeth can squeeze each other under the action of the two groups of end heads being stuck to each other and between the two connected water supply and drainage pipes, generating a certain preload and friction force. The unique structure of the saw teeth only allows the two groups of end heads to slide a short distance along the bevel tooth surface, and this sliding process will generate a lifting tension to resist further loosening, which can effectively ensure the stability of the connection. A number of evenly arranged saw teeth are provided on the side of the end head away from the sound insulation layer; the cross-section of the saw teeth is a right-angled triangle structure, and the groove formed between the two adjacent groups of saw teeth cooperates with the raised portion where the right-angled side of the saw teeth is located.

[0011] The beneficial effects of the utility model are:

[0012] The utility model realizes sound insulation and heat preservation of water supply and drainage pipes by setting a sound insulation and heat preservation layer, realizes uniform support of water supply and drainage pipes and prevents water supply and drainage pipes from being damaged by external forces by coordinating the buffer layer and the protective shell, thereby enabling the water supply and drainage pipes to adapt to complex stress environments.

[0013] By setting up a sound insulation and heat preservation layer, a closed air cavity can be formed under the cooperation of panel one, honeycomb core and panel two. When sound waves pass through these air cavities, they will be reflected on the cavity wall and produce multiple reflections and interferences, causing the sound energy to be gradually converted into heat energy and dissipated, thereby weakening the penetration of the sound waves and achieving a sound insulation effect; and because air is a poor conductor of heat, a large number of closed air cavities form a good thermal insulation barrier, which effectively slows down the conduction of heat energy and achieves a significant barrier to the transfer of heat energy, thereby achieving an excellent thermal insulation effect.

[0014] By setting up a buffer layer, all the airbags can be connected to each other through the connecting air pipe to form an integrated buffer network, thereby evenly distributing the pressure on the pipeline in the entire buffer network and avoiding pressure concentration at a single location on the pipeline.

[0015] By setting the end heads, the two sets of saw teeth can be squeezed against each other under the action of the two sets of end heads being stuck to each other and between the two connected water supply and drainage pipes, generating a certain preload and friction force. The unique structure of the saw teeth only allows the two sets of end heads to slide a short distance along the bevel tooth surface, and this sliding process will generate a lifting tension to resist further loosening, which can effectively ensure the stability of the connection.

[0026] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments. They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in the field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0027] According to an embodiment of the utility model, a water supply and drainage pipeline protection structure is provided.

[0028] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-7 As shown, according to the water supply and drainage pipe protection structure of the embodiment of the utility model, the water supply and drainage pipe protection structure is sleeved on the outer side of the circumference of the water supply and drainage pipe 1, and the sound insulation layer 2 is installed on the outer side of the water supply and drainage pipe 1, and the outer side of the sound insulation layer 2 is sleeved with a buffer layer 3, and the outer side of the buffer layer 3 is sleeved with a protective shell 4, and both ends of the protective shell 4 are provided with end caps 5, and the inner side of the end caps 5 are connected to the sound insulation layer 2 and the buffer layer 3.

[0029] In addition, it should be noted that the above-mentioned protective shell 4 is galvanized steel. Due to its high strength and durability, it is used to directly wrap the outside of the water supply and drainage pipe to provide physical protection and prevent external mechanical damage, environmental corrosion, etc. The protective shell 4 is a prior art and will not be elaborated in detail here.

[0030] With the aid of the above-mentioned technical scheme of the utility model, the utility model realizes sound insulation and heat preservation of the water supply and drainage pipes by setting the sound insulation layer 2, and realizes uniform support of the water supply and drainage pipes and prevents the water supply and drainage pipes from being damaged due to external forces through the coordinated setting of the buffer layer 3 and the protective shell 4, so that the water supply and drainage pipes can adapt to complex stress environments.

[0031] In one embodiment, for the above-mentioned sound insulation layer 2, the sound insulation layer 2 includes a panel 201 which is sleeved on the outside of the water supply and drainage pipe 1, and a plurality of honeycomb cores 202 are arranged on the outside of the panel 1 201, and a panel 2 203 is arranged on the side of the honeycomb core 202 away from the water supply and drainage pipe 1; the cross-section of the honeycomb core 202 is a regular hexagonal structure, and two adjacent groups of honeycomb cores 202 share a common side; under the cooperation of the panel 1 201, the honeycomb core 202 and the panel 2 203, a closed air cavity can be formed. When sound waves pass through these air cavities, they will be reflected on the cavity wall and produce multiple reflections and interferences, resulting in the gradual conversion of sound energy into heat energy dissipation, thereby weakening the penetration of sound waves and achieving sound insulation effect; and because air is a poor conductor of heat, a large number of closed air cavities form a good thermal insulation barrier, which effectively slows down the conduction of heat energy and achieves a significant barrier to heat energy transfer, thereby achieving an excellent thermal insulation effect.

[0032] Working principle of the sound insulation and heat preservation layer 2: under the action of panel 1 201 and panel 2 203 sealing the honeycomb core 202, the honeycomb core 202 forms a closed air cavity with a hexagonal structure. When the water flow sound of the water flow in the water supply and drainage pipe passes through these air cavities, it will be reflected on the cavity wall and produce multiple reflections and interferences, causing the sound energy to gradually be converted into heat energy and dissipated, thereby weakening the penetration of sound waves and achieving sound insulation effect; and because air is a poor thermal conductor, a large number of closed air cavities form a good thermal insulation barrier, which effectively slows down the conduction of heat energy and achieves a significant barrier to heat energy transfer, thereby achieving an excellent thermal insulation effect, which can not only keep the water in the pipe warm, but also prevent the pipe from freezing and cracking in cold weather.

[0033] In one embodiment, for the above-mentioned buffer layer 3, the buffer layer 3 includes a plurality of air bags 301 which are sleeved on the outside of the sound insulation layer 2, and two adjacent groups of air bags 301 are connected by a connecting air pipe 302; a support plate 303 is provided on the side of the air bag 301 away from the water supply and drainage pipe 1; the plurality of air bags 301 are evenly arranged and distributed in a rectangular shape on one side of the support plate 303; under the action of the connecting air pipe 302 connecting the air bags 301, all the air bags 301 can be constructed into an integral buffer network, thereby achieving a balanced distribution of the pressure on the pipeline in the entire buffer network, avoiding pressure concentration at a single position on the pipeline.

[0034] The working principle of the buffer layer 3 is as follows: under the action of the connecting air pipe 302 connecting the air bags 301, all the air bags 301 are constructed into an integrated buffer network. The pressure at a single position on the pipeline is concentrated, and the pipeline will squeeze the air bag 301 at the corresponding position. At this time, the gas squeezed out of the air bag 301 will be squeezed into the adjacent air bag 301 through the connecting air pipe 302, thereby dispersing the pressure on the pipeline in the entire buffer network through the connecting air pipe 302, thereby achieving a balanced distribution of the pressure on the pipeline and avoiding deformation caused by pressure concentration at a single position on the pipeline.

[0035] In one embodiment, for the above-mentioned end head 5, a side of the end head 5 away from the sound insulation layer 2 is provided with a plurality of evenly arranged saw teeth 501; the cross section of the saw teeth 501 is a right-angled triangle structure, and the groove formed between two adjacent groups of saw teeth 501 cooperates with the raised portion where the right-angled side of the saw teeth 501 is located; when the two groups of end heads 5 are mutually clamped and between two connected water supply and drainage pipes, the two groups of saw teeth 501 can squeeze each other to generate a certain preload and friction force, and the unique structure of the saw teeth 501 only allows the two groups of end heads 5 to slide a short distance along the bevel tooth surface, and this sliding process will generate a lifting tension to resist further loosening, which can effectively ensure the stability of the connection.

[0036] Working principle of the terminal 5: When two water supply and drainage pipes are connected, the saw teeth 501 on the two sets of terminal heads 5 at the connection point can engage with each other, and then under the action of the right-angled triangle structure of the saw teeth 501, when the water supply and drainage pipe vibrates, the terminal head 5 can only slide a short distance along the hypotenuse of the right-angled triangle, and this sliding process will generate a lifting tension to resist further loosening, so that the two sets of terminal heads 5 generate a certain pre-tightening force and friction force, which can effectively ensure the stability of the protective structure of the water supply and drainage pipe after connection.

[0037] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0038] In actual application, when the sound of water flow is generated in the water supply and drainage pipe, the sound insulation layer 2 is used for sound insulation, and the water in the pipe is insulated by the sound insulation layer 2. When a certain position on the pipe is under pressure, the pressure is dispersed by the buffer layer 3 to avoid excessive concentration of pressure to cause deformation of the pipe. The pipe is also isolated from the outside world by the protective shell 4 to avoid corrosion and weathering caused by contact with the outside world. The hardness of the protective shell 4 prevents the pipe from being punctured or other physical damage. At the same time, when the water supply and drainage pipe is vibrated by factors such as water flow, the protective structure can still maintain stability through the end 5.

[0039] In summary, with the aid of the above-mentioned technical scheme of the utility model, the sound insulation and heat preservation of the water supply and drainage pipes are achieved through the setting of the sound insulation and heat preservation layer 2, and the uniform support of the water supply and drainage pipes is achieved through the coordinated setting of the buffer layer 3 and the protective shell 4, and the water supply and drainage pipes are prevented from being damaged by external forces, so that the water supply and drainage pipes can adapt to complex stress environments; by setting the sound insulation and heat preservation layer 2, a closed air cavity can be formed under the coordinated action of the panel 1 201, the honeycomb core 202 and the panel 2 203. When sound waves pass through these air cavities, they will be reflected on the cavity wall and produce multiple reflections and interferences, resulting in the gradual conversion of sound energy into heat energy dissipation, thereby weakening the penetration of sound waves and achieving sound insulation effect; and because air is a poor heat conductor, a large number of closed air cavities form a good heat insulation barrier. It effectively slows down the conduction of heat energy and realizes a significant barrier to the transfer of heat energy, thereby achieving an excellent thermal insulation effect; by setting the buffer layer 3, the airbags 301 can be connected by the connecting air pipe 302, so that all the airbags 301 can be constructed into an integral buffer network, thereby achieving a balanced distribution of the pressure on the pipeline in the entire buffer network, and avoiding the concentration of pressure at a single position on the pipeline; by setting the end head 5, the two groups of serrations 501 can be squeezed against each other by the action of the two groups of end heads 5 being stuck to each other and between the two connected water supply and drainage pipes, so as to generate a certain preload and friction force, and the unique structure of the serrations 501 only allows the two groups of end heads 5 to slide a short distance along the bevel tooth surface, and this sliding process will generate a lifting tension to resist further loosening, which can effectively ensure the stability of the connection.

Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.
