Description

Technical Field

[0001] The utility model belongs to the field of water pipe installation, in particular to an outdoor water pipe insulation system. Background Art

[0002] As a means of transporting water for households or industries, water pipes have become an indispensable part. With the emergence of high-rise buildings, people have higher and higher requirements for the fast and safe installation and convenient maintenance of water pipes based on high-rise buildings. In addition, it is also necessary to have a good thermal insulation effect, because in cold areas or in winter, household water pipes are easily affected by low temperatures, causing the water temperature to drop, which not only affects the comfort of water use, but may also cause the water pipes to be frozen and unable to supply water or directly frozen and cracked. Once the water pipes are frozen or cracked, it will directly affect the water supply, causing many difficulties in life or production and even huge losses.

[0003] For outdoor water pipe insulation, traditional insulation methods such as coating with foam cotton and rock wool can solve the problem to a certain extent, but the installation is complicated, the insulation effect is limited, and it is not easy to maintain. Therefore, it is necessary to provide a water pipe insulation method with a simple structure, easy installation, and better insulation effect to solve the above problems, especially to meet the needs of high-rise residential buildings. Utility Model Content

[0004] The utility model aims to provide an outdoor water pipe insulation system which can be installed quickly and safely, is convenient for water pipe maintenance, and can further reduce the risk of water pipes being frozen and cracked, and is flexible to install and use.

[0005] The utility model is realized by the following technical solutions:

[0006] The outdoor water pipe insulation system comprises a main insulation pipe for wrapping the water pipe and a plurality of inlet insulation pipes connected to the main insulation pipe. When a water pipe in the main insulation pipe or the inlet insulation pipe needs to pass through a wall to enter a house, a pipe wall insulation structure for the water pipe to pass through is also embedded in the wall through which the water pipe passes, so as to closely cooperate with the main insulation pipe or the inlet insulation pipe. The pipe wall insulation structure comprises an outer tube for embedding in an opening on the wall and an inner insulation tube inserted in the outer tube, the outer diameter of which can be matched with the inner diameter of the outer tube, and a through hole for the water pipe to pass through is opened on the inner insulation tube.

[0007] The reason for setting up the pipe-in-wall insulation structure is that the inventor found that the traditional water pipe insulation method, because the wall has its own windproof and heat-insulating function, usually only takes insulation measures for the water pipes exposed outside the wall when the water pipes are insulated. The setting of these insulation measures does improve the situation of water pipes being frozen and cracked. However, the inventor found that when the weather is cold, the water pipes are often frozen or cracked at or from the wall. Therefore, the inventor thought that if a device is designed that can also have a good insulation effect on the water pipes in the wall, that is, the water pipes are allowed to pass through the wall into the house by passing through a pipe-in-wall insulation structure embedded in the wall, the risk of the water pipes being frozen or cracked can definitely be further reduced.

[0008] Preferably, the inner thermal insulation cylinder is made of thermal insulation material.

[0009] More preferably, the thermal insulation material is a flame retardant thermal insulation material.

[0010] More preferably, the thermal insulation material is flame-retardant foam, rock wool, glass fiber thermal insulation wool, etc.

[0011] Preferably, the outer tube is provided with a circle of outward flange on one end, which is used to fix the outer tube to the main insulation pipe or the sub-insulation pipe for entering the house. Specifically, at the place where the water pipe passes through, a hole for the water supply pipe to pass through is opened on the main insulation pipe or the sub-insulation pipe for entering the house, and the flange on the outer tube is fixedly connected to the periphery of the hole, thereby sealing and fixing the outer tube and the main insulation pipe or the sub-insulation pipe for entering the house together.

[0012] Preferably, the outer cylinder and the wall are fixed by an adhesive or the like. The adhesive includes bubble glue, cement concrete, and the like.

[0013] Preferably, the main insulation pipe and the sub-insulation pipe both include a base plate for installation close to the wall and a cover plate that can cooperate with the base plate, and a cavity for the water supply pipe to pass through is formed between the base plate and the cover plate. By arranging the cover plate on the base plate, when installing the water pipe and needing maintenance, it is only necessary to open the cover plate, which is very convenient for subsequent maintenance and repair; on the inner walls of the base plate and the cover plate, at least on the inner wall of the base plate, an insulation layer is provided, so as to achieve a better insulation effect; a plurality of pipe clamps are also fixedly provided on the base plate in sequence, and the pipe clamps are provided with a plurality of water pipe clamp grooves for the water pipes to be inserted, and the openings of the water pipe clamp grooves face one side of the cover plate. The outward arrangement of the openings of the water pipe clamp grooves can make the installation of the water pipes more convenient, because during installation, the water pipes can be directly inserted into the water pipe clamp grooves of the pipe clamps that have been installed in advance to quickly fix the water pipes, which is much more convenient than the previous method of arranging the water pipes first and then clamping the water pipes with pipe clamps for fixing, saving a lot of time and effort.

[0014] More preferably, a top cover for sealing the bottom plate and the cover plate is provided at the top position of the main insulation pipe and the end position of the house-entry sub-insulation pipe. Furthermore, an insulation layer is also provided inside the top cover.

[0015] Preferably, the base plate and the cover plate are fixed to the wall together by means of clamps that can be fixed to the wall at both ends, so that when fixing the base plate and the cover plate, the fixing parts fixing the base plate and the cover plate do not need to penetrate the insulation layer, thereby avoiding the problem caused by the method of fixing the base plate and the cover plate to the wall by driving screws from the top of the cover plate downwards, that is, the screws will penetrate the insulation layer on the base plate and the cover plate, and cold air can easily enter the cavity surrounded by the base plate and the cover plate from the holes in the insulation layer, that is, enter the outdoor water pipe insulation system, directly reducing the overall insulation performance of the system. The utility model fixes the base plate and the cover plate by means of outer jacket clamps, which can avoid perforation of the insulation layer and effectively ensure the overall insulation performance of the system.

[0016] Preferably, the base plate and the cover plate are both connectable structures, and the upper and lower ends of the base plate and the cover plate are respectively provided with male and female heads that can cooperate with each other, and two adjacent sections of the base plate and the cover plate are connected by the combination of the male and female heads.

[0017] More preferably, the water pipe clamping groove is an elastic arc-shaped structure to facilitate the insertion and fixing of the water pipe.

[0018] More preferably, the back side of the bottom plate is further fixedly connected with a plurality of fixing bars whose two ends extend beyond the two sides of the bottom plate.

[0019] Furthermore, the two ends of the clamp and the two ends of the fixing strip are fixed to the wall through bolts.

[0020] Preferably, the main insulation pipe includes a low-floor section and a high-floor section, the width of the low-floor section is greater than the width of the high-floor section, and a transition pipe section for connecting the low-floor section and the high-floor section is provided between the low-floor section and the high-floor section, and the transition pipe section is sealed and connected to the low-floor section and the high-floor section. Because the water pipes are installed from bottom to top along the building, the higher the number of residents, the fewer the number of water pipes on the wall. By using a narrower main insulation pipe in the high-floor section, the material used in the high-floor section can be saved, and the space inside the pipe in the high-floor section can be smaller, making it easier to insulate the water pipes.

[0021] More preferably, the transition pipe section has a structure that is smaller at the top and larger at the bottom.

[0022] Preferably, the outdoor water pipe insulation system also includes an adjustable support frame fixed to the wall and used to support the main insulation pipe or the house-entry sub-insulation pipe as needed to facilitate it to avoid obstacles.

[0023] Preferably, the connection between the inlet insulation pipe and the main insulation pipe is connected through or without a connecting pipe with an arc-shaped channel inside, so that the water pipe can turn in an arc, avoiding damage due to excessive bending when the water pipe is separated from the main insulation pipe.

[0024] The beneficial effects of the utility model are:

[0025] The outdoor water pipe insulation system of the utility model has an ingenious structure. By arranging a pipe-in-wall insulation structure at the place where the water pipe passes through the wall, the insulation dead zone of the existing outdoor water pipe insulation system is directly eliminated, and the problem of pipe bursting that is prone to occur at the water pipe entrance in cold weather is solved, thereby greatly improving the safety of water pipe use. In addition, the method of fixing the bottom plate and the cover plate by the outer jacket clamp can avoid perforation of the insulation layer inside the bottom plate and the cover plate, which can effectively ensure the overall insulation performance of the system. By arranging a transition pipe section connecting the low-floor section and the high-floor section, raw materials can be greatly saved. The utility model has strong practicality and is worthy of promotion. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0036] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0037] like Figure 1-8 As shown, the outdoor water pipe insulation system includes a main insulation pipe 10 for wrapping the water pipe 40 and a plurality of household insulation pipes 20 connected to the main insulation pipe 10. When a water pipe 40 in the main insulation pipe 10 or the household insulation pipe 20 needs to pass through the wall to enter the house, a pipe wall insulation structure 30 for the water supply pipe 40 to pass through is also embedded in the wall through which the water pipe 40 passes, so as to closely cooperate with the main insulation pipe 10 or the household insulation pipe 20; the pipe wall insulation structure 30 includes an outer tube 31 for being embedded in an opening on the wall and an inner insulation tube 32 inserted in the outer tube 31 and having an outer diameter that can be matched with the inner diameter of the outer tube 31, and a through hole 33 for the water pipe 40 to pass through is opened on the inner insulation tube 32.

[0038] The reason why the pipe wall insulation structure 30 is provided is that the inventor has found that the traditional water pipe insulation method, because the wall has its own windproof and heat-insulating function, usually only takes insulation measures for the water pipes exposed outside the wall when the water pipes 40 are insulated. The provision of these insulation measures does improve the situation of the water pipes being frozen and cracked. However, the inventor has found that when the weather is cold, the water pipes 40 are often frozen or cracked at or from the wall. Therefore, the inventor thought that if a device that can also have a good insulation effect on the water pipes in the wall is designed, the risk of the water pipes being frozen or cracked can definitely be further reduced.

[0039] The inner heat-insulating cylinder 32 is made of flame-retardant heat-insulating material.

[0040] The thermal insulation material is flame retardant foam, rock wool, glass fiber thermal insulation wool, etc.

[0041] The main insulation pipe 10 and the sub-insulation pipe 20 both include a bottom plate 1 for installation close to the wall and a cover plate 2 that can cooperate with the bottom plate 1. A cavity for the water supply pipe to pass through is formed between the bottom plate 1 and the cover plate 2. By arranging the cover plate 2 on the bottom plate 2, when installing the water pipe and needing maintenance, it is only necessary to open the cover plate 2, which is very convenient for subsequent maintenance and repair; a flame-retardant insulation layer 3 is provided on the inner walls of the bottom plate 1 and the cover plate 2 to facilitate better insulation effect; a plurality of fixedly provided layers are provided on the bottom plate 1 along the length direction. A pipe clamp 4 is provided, and a plurality of water pipe clamp grooves 5 for the water pipe 40 to be clamped into are arranged in parallel on the pipe clamp 4. The number of the pipe clamps 4 and the number of the water pipe clamp grooves 5 arranged thereon can be selected and installed according to actual needs. The opening of the water pipe clamp groove 5 faces one side of the cover plate 2. The setting of the water pipe clamp groove 5 opening outward can make the installation of the water pipe more convenient, because during installation, the water pipe can be directly clamped into the pre-installed pipe clamp water pipe clamp groove 5 to quickly fix the water pipe. Compared with the previous method of arranging the water pipes first and then clamping the water pipes with pipe clamps for fixing, it is much more convenient and saves a lot of time and effort.

[0042] The outer tube 31 is provided with a circle of outward flange 34 at one end close to the main insulation pipe 10 or the household insulation pipe 20, which is used to fix the outer tube 31 to the main insulation pipe 10 or the household insulation pipe 20. Specifically, at the place where the water pipe 40 passes through, a hole for the water supply pipe 40 to pass through is opened on the main insulation pipe 10 or the household insulation pipe 20, and the flange 34 on the outer tube 31 is fixedly connected to the periphery of the hole, thereby sealing and fixing the outer tube 31 and the main insulation pipe 10 or the household insulation pipe 20 together.

[0043] The outer cylinder 31 is fixed to the wall by an adhesive, which includes air bubble glue, cement concrete, etc.

[0044] A top cover 6 for sealing the bottom plate 1 and the cover plate 2 is provided at the top of the main insulation pipe 10 and the end of the inlet insulation pipe 20, and an insulation layer is also provided inside the top cover 6.

[0045] The base plate 1 and the cover plate 2 are fixed to the wall together through the clamps 7 that can be fixed to the wall at both ends, so that when fixing the base plate 1 and the cover plate 2, the fixing parts fixing the base plate 1 and the cover plate 2 do not need to penetrate the insulation layer 3. Therefore, it can be avoided that the method of fixing the base plate 1 and the cover plate 2 to the wall by driving screws from the top of the cover plate 2 will cause problems, that is, the screws will penetrate the insulation layer 3 on the base plate 1 and the cover plate 2, and cold air can easily enter the cavity surrounded by the base plate and the cover plate from the holes in the insulation layer, that is, enter the outdoor water pipe insulation system, directly reducing the overall insulation performance of the system. The utility model fixes the base plate 1 and the cover plate 2 by the outer jacket clamp 7, which can avoid the insulation layer 3 from being pierced, and effectively ensure the overall insulation performance of the system.

[0046] The base plate 1 and the cover plate 2 are both connectable structures, and the upper and lower ends of the base plate 1 and the cover plate 2 are respectively provided with male and female heads that can cooperate with each other, and the two adjacent sections of the base plate 1 and the cover plate 2 are connected by the combination of the male and female heads.

[0047] The water pipe clamping groove 5 is an elastic arc-shaped structure to facilitate the insertion and fixing of the water pipe 40 .

[0048] The back side of the bottom plate 1 is also fixedly connected with a plurality of fixing bars 8 with both ends extending beyond the two sides of the bottom plate 1 .

[0049] The two ends of the clamp 7 and the two ends of the fixing strip 8 are fixed to the wall by bolts.

[0050] The main insulation pipe 10 includes a low-floor section 11 and a high-floor section 12. The width of the low-floor section 11 is greater than that of the high-floor section 12. A transition pipe section 13 for connecting the low-floor section 11 and the high-floor section 12 is provided between the low-floor section 11 and the high-floor section 12. The transition pipe section 13 is sealed and connected to the low-floor section 11 and the high-floor section 12. Because the water pipes are installed from bottom to top along the building, the higher the number of households, the fewer the number of water pipes 40 on the wall. By using a narrower main insulation pipe in the high-floor section 12, the materials used on the high-floor section can be saved, and the space inside the high-floor section 12 pipe is smaller, making it easier to insulate the water pipes 40.

[0051] The transition pipe section 13 is a structure that is small at the top and large at the bottom. Figure 8 As shown, sequentially, the upper small part of the transition pipe section 13 can be located on the left, middle or right side above the lower large part, and construction workers can select and install it according to actual needs.

[0052] The outdoor water pipe insulation system also includes an adjustable support frame 14 fixed to the wall for supporting the main insulation pipe 10 or the household insulation pipe 20 as needed, so that it can avoid obstacles. Specifically, the adjustable support frame 14 includes a top clamp and a bottom fixing member, and the top clamp and the bottom fixing member are both provided with an adjustment slide. By locking the top clamp and the bottom fixing member at different positions of the adjustment slide, the support height of the main insulation pipe 10 or the household insulation pipe 20 can be adjusted as needed.

[0053] The connection between the inlet insulation pipe 20 and the main insulation pipe 10 is connected through or without a connecting pipe 15 with an arc-shaped channel inside, so that the water pipe 40 can turn in an arc, avoiding damage to the water pipe due to excessive bending when it is separated from the main insulation pipe.

[0054] When in use, the main insulation pipe 10 and the household insulation pipe 20 are installed on the outer wall of the building as needed. The main insulation pipe 10 and the household insulation pipe 20 are formed by connecting sections of the base plate 1 and the cover plate 2 together end to end. The fixing strip 8 is fixed to the back of the base plate 1, and the pipe clamp 4 is fixed to the base plate 1 by bolts. The required number of water pipes 40 are clamped in the water pipe clamp groove 5 of the pipe clamp 4 in sequence. The cover plate 2 covers the outside of the base plate 1, and the upper ends of the base plate 1 and the cover plate 2 are sealed at the top or end by the top cover 30. After the installation is completed, the main insulation pipe 10 and the household insulation pipe 20 are fixed to the wall by the clamp 7 that sequentially covers the cover plate 2 and the base plate 1 from the outside and the fixing strip 8 fixed to the base plate 1.

[0055] When a water pipe 40 on the main insulation pipe 10 or the household insulation pipe 20 needs to pass through the wall to enter the house, a wall hole is dug at the wall penetration point, and the outer tube 31 of the pipe-entry wall insulation structure 30 is embedded in the wall hole, and the inner insulation tube 32 is plugged in the outer tube. A hole for the water supply pipe 40 to pass through is opened at the corresponding position of the bottom plate of the main insulation pipe 10 or the household insulation pipe 20, and the flange 34 on the outer tube 31 is fixedly connected to the periphery of the hole, so that the water pipe 40 passes through the wall by passing through the through hole 33 opened on the inner insulation tube 32 for the water pipe 40 to pass through, so that the water pipe 40 is protected by the inner insulation tube in the entire area where it passes through the wall to prevent it from freezing at the wall penetration point, thereby improving or completely solving the problem that the water pipe 40 is easily frozen or cracked at the wall penetration point in cold weather.

[0056] When encountering obstacles on the wall, the main insulation pipe 10 and the house-entry insulation pipe 20 are set as a curved bridge structure, and at the same time, the adjustable support frame 14 is used to support the place where there is an obstacle, so that it can avoid the obstacle while maintaining stability.

[0057] The outdoor water pipe insulation system of the present invention has an ingenious structure. By arranging a pipe-in-wall insulation structure at the place where the water pipe 40 passes through the wall, the insulation dead zone of the existing outdoor water pipe insulation system is directly eliminated, and the problem of pipe bursting that is prone to occur at the water pipe entrance in cold weather is solved, thereby greatly improving the safety of water pipe use. In addition, the method of fixing the bottom plate and the cover plate by the outer jacket clamp can avoid perforation of the insulation layer inside the bottom plate and the cover plate, which can effectively ensure the overall insulation performance of the system. By arranging a transition pipe section connecting the low-floor section and the high-floor section, raw materials can be greatly saved. The utility model has strong practicality and is worthy of promotion.

[0058] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
