Description

Technical Field

[0001] This utility model relates to the field of pipeline protection technology, and in particular to a water pipe protection device with antifreeze function. Background Technology

[0002] In cold regions or low-temperature environments, the freezing of liquid inside water pipes due to heat loss is a common and serious problem. Ice formation not only obstructs normal water flow but can also exert excessive pressure on the pipes due to the expansion effect of ice, leading to pipe cracking or damage. This problem is particularly prominent in outdoor water supply pipelines, industrial water transmission pipelines, and agricultural irrigation systems, affecting daily life and production water needs, and potentially resulting in high maintenance costs and economic losses.

[0003] Currently, common methods for protecting water pipes from freezing often involve wrapping them with a single layer of insulation material. However, this method has limited effectiveness in prolonged low-temperature environments and cannot provide lasting and effective insulation protection. Furthermore, when water pipes are exposed to the outdoors, they are susceptible to impacts, heavy pressure, or ground subsidence, further increasing the risk of damage.

[0004] Existing water pipe protection devices also have some shortcomings in practical use. Their installation and disassembly processes are often complex, and their sealing performance is poor. For example, traditional devices are usually fixed with screws, which is not only time-consuming and labor-intensive, but also prone to loosening due to long-term use or external vibrations, affecting the stability and sealing of the device. Disassembly of these devices is also difficult when water pipes need maintenance or replacement, causing considerable inconvenience to users and reducing their practicality and convenience.

[0005] Therefore, a water pipe protection device with antifreeze function is proposed to solve the above problems. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a water pipe protection device with antifreeze function, which aims to improve the problems of insufficient heat preservation performance, poor pressure resistance and cumbersome installation and disassembly in the prior art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a water pipe protection device with antifreeze function, comprising an upper insulation pipe sleeve and a lower insulation pipe sleeve, wherein the upper insulation pipe sleeve and the lower insulation pipe sleeve are rotatably connected on one side by multiple connecting shafts, and protective components are provided inside the upper insulation pipe sleeve and the side of the lower insulation pipe sleeve away from the connecting shaft is fixedly connected to more than one insert block, and a fixing block corresponding to the number of insert blocks is fixedly connected on the side of the lower insulation pipe sleeve away from the connecting shaft, wherein a fixing mechanism is provided inside the fixing block; The protective component includes a protective sleeve, which is fixedly connected to the inner walls of the upper insulation sleeve and the lower insulation sleeve, and an inner insulation sleeve is fixedly connected to the inner wall of the protective sleeve.

[0008] As a further description of the above technical solution: The fixing mechanism includes an outer shell, the outer side of which is fixedly connected to the inside of the fixing block, and an inner shell fixedly connected to the inside of the outer shell. A pin is slidably connected inside the inner shell, a spring is sleeved on the outside of the pin, and a self-locking component is provided on the outside of the pin.

[0009] As a further description of the above technical solution: The self-locking assembly includes an L-shaped rod and a pad. The L-shaped rod is fixedly connected to the outside of the pad, and the middle part of the pad is fixedly connected to the outside of the pin. An L-shaped groove is provided on the outside of the inner shell, and an arc-shaped groove is provided on the end of the outer shell away from the fixing block.

[0010] As a further description of the above technical solution: The protective sleeve is internally fixedly connected with a steel mesh.

[0011] As a further description of the above technical solution: The bottom of the insert block is inserted into the inside of the fixing block, and the pin is inserted into the inside of the insert block.

[0012] As a further description of the above technical solution: The pad is slidably connected inside the inner shell, and a pull ring is fixedly connected to the end of the pin away from the fixing block.

[0013] As a further description of the above technical solution: The L-shaped rod is slidably connected inside the L-shaped groove and the arc-shaped groove.

[0014] As a further description of the above technical solution: The inner insulation sleeve contains a water pipe body, and the outer side of the water pipe body abuts against the inner wall of the inner insulation sleeve.

[0015] This utility model has the following beneficial effects: 1. In this utility model, the fixing mechanism makes the connection between the upper and lower insulation sleeves more stable and easier to operate. During installation, the user first easily pulls the pin using the pull ring, and then rotates the pin to lock the L-shaped rod into the L-shaped groove without continuous force. After the insert block is inserted into the fixing block, the pin is then rotated to allow it to insert into the insert block, thus achieving a simple installation operation. When disassembly is required, the user simply pulls the pin to remove it from the insert block, easily completing the disassembly of the device, greatly improving the ease of operation and maintenance efficiency.

[0016] 2. In this utility model, the water pipe body is fully protected by a multi-layer insulation structure. The upper and lower insulation sleeves effectively isolate the intrusion of cold air and moisture from the outside, while the inner insulation sleeve further prevents the loss of heat inside the water pipe, ensuring that the water flow inside the water pipe body remains unobstructed even in extreme low-temperature environments, and preventing pipe blockage or freezing cracks caused by water freezing.

[0017] 3. In this utility model, the use of steel mesh as an internal support structure significantly improves the compressive strength of the protective sleeve. In the event of impact or pressure, the device can effectively absorb and disperse external forces, preventing damage to the water pipe body due to accidental impact or compression, thus significantly improving the service life and safety of the water pipe.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figure 1 - Figure 4An embodiment of this utility model provides a water pipe protection device with antifreeze function, including an upper insulation pipe sleeve 1 and a lower insulation pipe sleeve 4. The upper insulation pipe sleeve 1 and the lower insulation pipe sleeve 4 are rotatably connected on one side by multiple connecting shafts 6. The upper insulation pipe sleeve 1 and the lower insulation pipe sleeve 4 are provided with protective components. More than one insert block 2 is fixedly connected to the side of the upper insulation pipe sleeve 1 away from the connecting shaft 6. The lower insulation pipe sleeve 4 is fixedly connected to the side away from the connecting shaft 6 with a fixing block 3 corresponding to the number of insert blocks 2. The fixing block 3 is provided with a fixing mechanism inside. The protective component includes a protective sleeve 7, which is fixedly connected to the inner walls of the upper insulation sleeve 1 and the lower insulation sleeve 4. An inner insulation sleeve 8 is fixedly connected to the inner wall of the protective sleeve 7. A steel mesh 9 is fixedly connected inside the protective sleeve 7. A water pipe body 5 is installed inside the inner insulation sleeve 8, and the outer side of the water pipe body 5 abuts against the inner wall of the inner insulation sleeve 8.

[0022] The upper insulation sleeve 1 and the lower insulation sleeve 4 are rotatably connected on one side by multiple connecting shafts 6, so that the upper insulation sleeve 1 and the lower insulation sleeve 4 can be opened and closed flexibly, which is convenient for installation and disassembly. The protective device can be quickly installed on the outside of the water pipe body 5 without complicated operation, which improves the convenience of use.

[0023] Protective components are installed inside the upper insulation sleeve 1 and the lower insulation sleeve 4. These components provide multi-layered protection for the water pipe body 5, effectively improving the device's pressure resistance and insulation performance. Multiple inserts 2 are fixedly connected to the side of the upper insulation sleeve 1 away from the connecting shaft 6. These inserts 2 cooperate with the fixing blocks 3 on the lower insulation sleeve 4 to achieve closed fixation of the upper and lower insulation sleeves 1 and 4. The inserts 2 are evenly distributed on the upper insulation sleeve 1, ensuring good sealing performance after the device is closed and effectively preventing cold air from entering the device. A number of fixing blocks 3 corresponding to the number of inserts 2 are fixedly connected to the side of the lower insulation sleeve 4 away from the connecting shaft 6. The fixing blocks 3 have internal fixing mechanisms that work in conjunction with the inserts 2 to further enhance the stability of the device and prevent loosening or detachment due to external forces or vibrations.

[0024] The core component of the protective assembly includes a protective sleeve 7, which is fixedly connected to the inner walls of the upper insulation sleeve 1 and the lower insulation sleeve 4. Its main function is to provide the first layer of protection for the water pipe body 5, while also enhancing the structural stability of the entire device. An inner insulation sleeve 8 is fixedly connected to the inner wall of the protective sleeve 7, providing a second layer of insulation protection for the water pipe body 5. The inner insulation sleeve 8 fits tightly against the outer side of the water pipe body 5, significantly reducing the direct impact of low temperatures on the water pipe body 5. A reinforcing mesh 9 is also fixedly connected inside the protective sleeve 7. The reinforcing mesh 9 effectively increases the strength of the protective sleeve 7, enhances its compressive strength, and further improves the overall impact resistance of the device.

[0025] The main body of the water pipe 5 is located inside the inner insulation sleeve 8 and is directly responsible for the transmission of water flow. Through the close contact between the inner insulation sleeve 8 and the main body of the water pipe 5, heat loss can be minimized, preventing the water inside the pipe from freezing due to low temperature, which could lead to obstructed flow or pipe cracking.

[0026] In summary, this device employs a multi-layered design, including an upper insulation sleeve 1, a lower insulation sleeve 4, a protective sleeve 7, an inner insulation sleeve 8, and a steel mesh 9, to create a robust protective structure for the main body of the water pipe 5. Furthermore, the cooperation of the insert block 2, the fixing block 3, and the fixing mechanism ensures the sealing and stability of the device after closure. The overall device not only possesses excellent insulation and freeze-resistance properties but also high compressive strength and service life, enabling long-term use in harsh low-temperature environments. It is a water pipe protection device suitable for various scenarios.

[0027] Reference Figure 1 , Figure 2 and Figure 4 The fixing mechanism includes a housing 12, which is fixedly connected to the outside of a fixing block 3. An inner housing 11 is fixedly connected inside the housing 12, and a pin 15 is slidably connected inside the inner housing 11. A spring 10 is sleeved on the outside of the pin 15, and a self-locking component is provided on the outside of the pin 15. The bottom of a plug block 2 is inserted into the inside of the fixing block 3, and the pin 15 is inserted into the inside of the plug block 2. The housing 12, fixedly connected to the inside of the fixing block 3, forms an external protective layer for the fixing mechanism and provides support for the overall structure. The housing 12 is made of high-strength material, which not only has good pressure resistance but also effectively prevents the influence of external environments (such as humidity or low temperature) on the internal fixing components, extending the service life of the fixing mechanism. The dimensions of the housing 12 are tightly fitted to the internal space of the fixing block 3, ensuring the stability of the fixing mechanism within the fixing block 3.

[0028] An inner shell 11 is fixedly connected inside the outer shell 12. Located at the center of the outer shell 12, the inner shell 11 is the main load-bearing component of the fixing mechanism. The inner shell 11 and the outer shell 12 are designed with a precise connection method to further enhance the overall strength of the fixing mechanism. A pin 15 is slidably connected inside the inner shell 11. The pin 15 is a key moving part of the fixing mechanism, responsible for engaging with the bottom of the insert block 2. Guided by the inner shell 11, the pin 15 can slide. The pin 15 is made of wear-resistant and corrosion-resistant high-strength metal material to ensure stability and durability during long-term use.

[0029] A spring 10 is fitted around the outside of the pin 15. The spring 10 provides the restoring force of the pin 15, enabling it to automatically return to its original position after sliding into the insert block 2. The spring force of the spring 10 is precisely calculated and adjusted to ensure not only the stability of the pin 15 insertion but also to prevent excessive spring force from causing inconvenience to the operation of the fixing mechanism. The compact installation structure of the spring 10 effectively saves space inside the fixing mechanism while ensuring the smooth operation of the entire fixing mechanism.

[0030] Reference Figure 4 The self-locking assembly includes an L-shaped rod 16 and a pad 17. The L-shaped rod 16 is fixedly connected to the outside of the pad 17. The middle part of the pad 17 is fixedly connected to the outside of the pin 15. An L-shaped groove 14 is provided on the outside of the inner shell 11. An arc-shaped groove 13 is provided at the end of the outer shell 12 away from the fixing block 3. The pad 17 is slidably connected inside the inner shell 11. A pull ring is fixedly connected at the end of the pin 15 away from the fixing block 3. The L-shaped rod 16 is slidably connected inside the L-shaped groove 14 and the arc-shaped groove 13. The pad 17 connects the L-shaped rod 16 and the bearing spring 10. When the pin 15 is pulled out of the fixing block 3, and then the pin 15 is rotated, the L-shaped rod 16 can be locked inside the L-shaped groove 14, thus completing the locking of the pin 15 without having to pull it forcefully. The arc groove 13 provides sliding space for the L-shaped rod 16 when the pin 15 is rotated. The pull ring facilitates pulling the pin 15. The spring 10 ensures that the pin 15 is firmly inserted into the insert block 2 without external force. Working Principle: In actual operation, the upper insulation sleeve 1 and the lower insulation sleeve 4 are rotatably connected on one side by multiple connecting shafts 6, forming a flexible opening and closing structure. During installation, the user can first rotate the upper insulation sleeve 1 and the lower insulation sleeve 4 around the water pipe body 5 to close them. During installation, first, the pin 15 needs to be pulled open, and the L-shaped rod 16 is inserted into the L-shaped groove 14 by rotating the pin 15, thus completing the self-locking function of the pin 15 and avoiding the need for the user to continuously pull the pin 15. Then, the insert block 2 on the upper insulation sleeve 1 is inserted into the fixing block 3 on the lower insulation sleeve 4. Next, by rotating the pin 15 again, the L-shaped rod 16 slides freely in the L-shaped groove 14. After releasing the pin 15, the pin 15 automatically springs back under the action of the spring 10 and is firmly inserted into the insert block 2. At this point, the stable installation of the device is completed.

[0031] After the device is closed, its protective components provide multi-layered protection for the water pipe body 5. First, the upper insulation sleeve 1 and the lower insulation sleeve 4 act as the first barrier, effectively isolating the intrusion of cold air and moisture from the outside. Simultaneously, the high compressive strength provided by the protective sleeve 7 prevents external forces from damaging the internal structure of the device. Second, the inner wall of the protective sleeve 7 is tightly connected to the inner insulation sleeve 8, which is in close contact with the outer wall of the water pipe body 5, forming a second layer of thermal insulation protection. This effectively blocks the influence of low external temperatures on the liquid inside the water pipe body 5, preventing it from freezing. The steel mesh 9, as the internal support structure of the protective components, further enhances the device's compressive strength and impact resistance, ensuring good structural integrity even under strong external impacts or pressure.

[0032] In low-temperature environments, the multi-layered structure of the protective components effectively blocks cold air from directly invading the main body of the water pipe 5, ensuring unobstructed water flow inside the pipe and preventing obstruction or cracking due to freezing. When disassembly is required, the user can pull the pull ring at the end of the pin 15 to remove it from the plug block 2, while simultaneously rotating the pin 15 to engage the L-shaped rod 16 in the self-locking component with the L-shaped groove 14, preventing the pin 15 from relocking due to the spring force of the spring 10. At this point, the plug block 2 is completely unlocked from the fixing block 3, and the upper insulation sleeve 1 and lower insulation sleeve 4 can be opened by rotating the connecting shaft 6, thus easily completing the disassembly of the device.

[0033] Through the aforementioned collaborative working process, the device not only provides efficient protection and sealing performance for the main body 5 of the water pipe in low-temperature environments, ensuring the normal flow of liquid inside the water pipe, but also has the advantages of convenient installation and disassembly, demonstrating wide applicability and practical value.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
