Description

Technical Field

[0001] The invention relates to the technical field of pipeline thawing, in particular to a shallow buried water supply pipeline thawing device. Background Art

[0002] In the scenario of taking water from natural water sources, especially in areas with exposed rocks, dense vegetation and complex terrain, traditional large-scale mechanical or manual trench excavation methods are difficult to implement. Due to geographical restrictions, the PE (polyethylene) water supply pipes in these areas cannot solve the problem of frozen pipes in winter by increasing the burial depth below the permafrost layer, and can only be buried shallowly according to the mountain terrain. However, this layout makes the pipeline extremely susceptible to low temperature environments. In winter, due to the combined effects of factors such as sudden drops in temperature and unstable water supply, frozen pipes frequently occur.

[0003] In response to the above problems, the main anti-freezing measures currently taken include: using groundwater as a water source (because its water temperature is relatively high), setting up constant water flow to maintain the water flow rate and ensure that hot water continuously replaces cold water, and using insulation materials such as insulation cotton to slow down the freezing of pipes. However, these methods cannot fundamentally solve the problem. For example, the solution of burying pipes deep below the permafrost layer is not feasible in such a complex environment; and the application of heating tapes is not considered because the lines are too long and forest fire prevention requirements cannot be met.

[0004] In addition, the variability of the natural environment further complicates the problem. For example, pollutants such as silt or dead branches and leaves entering the pipe system will reduce the flow rate, thereby increasing the risk of freezing of water pipes. In addition, if human factors cause the normal flow valve to be closed, it will directly cause the water pipes to freeze, and once frozen, there is often no effective way to thaw it, which will seriously affect the water demand throughout the winter.

[0038] It should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "set", "install", "connect", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] The following will be combined with the attached Figure 1-5 , the present invention is further described.

[0040] In the embodiment of the present invention, Figure 1-Figure 5As shown, the shallow buried water supply pipe thawing device comprises: a water storage tank 1, a first pipe body 2, a second pipe body 3 and two joint assemblies 4; the water storage tank 1 is provided with a pressure stabilizing tank and a heating rod, and has a water inlet and a water outlet; the first pipe body 2 is connected to the water inlet; the second pipe body 3 is connected to the water outlet; two joint assemblies 4 are respectively arranged on the first pipe body 2 and the second pipe body 3, the joint assembly 4 comprises a matching female end joint 401 and a male end joint 402, and a clamping structure arranged on the matching surface of the female end joint 401 and the male end joint 402, the female end joint 401 is connected to the first pipe body 2 or the second pipe body 3, the male end joint 402 is used for external water supply pipe or water supply pipe, and the clamping structure has a clamping position for clamping and fixing the female end joint 401 and the male end joint 402, and a releasing position for releasing the male end joint 402 in its movable stroke;

[0041] Among them, in the clamping position, the water supply pipe, the first tube body 2, the water tank 1, the second tube body 3 and the water supply pipe are connected in sequence to form a first path, the pressure value in the water tank 1 is 0.1Mpa-0.6Mpa, and its temperature value is 10℃-60℃, which is used to thaw the water supply pipe; in the releasing position, the water tank 1 is disconnected from the first tube body 2 and the second tube body 3 to form a second path, the pressure value in the water tank 1 is 0.1Mpa, and its temperature value is 60℃, which is used to keep the water tank 1 warm.

[0042] Specifically, in the embodiment of the present invention, the water tank 1 is provided with a motor power junction box, a motor, a control button, a control box, an equipment base, a pressure gauge, a voltage regulator tank, a data display screen, a heating rod, etc., and a water inlet and a water outlet are formed on its surface. The water inlet is connected to the water supply pipe through the first pipe, and the water outlet is connected to the water supply pipe through the second pipe. When the water supply pipe is connected externally, the segmentation method is adopted; that is: according to the on-site pipeline layout and the freezing conditions, the pipeline is divided into several small sections, and the dividing points should be selected at the elbow, reducer, branch, valve, etc. The length is selected according to the following table:

[0043] Pipe Specifications Single-stage thawing pipe length (m) DN20 ≤400 DN25 ≤320 DN32 ≤250 DN50 ≤160 DN80 ≤100 DN100 ≤80 DN150 ≤55 DN200 ≤40

[0044] In the embodiment of the present invention, a joint assembly 4 is provided at the end of the first pipe and the second pipe for externally connecting a water supply pipe or a water supply pipe. Specifically, the joint assembly 4 includes a female joint 401, a male joint 402 and a clamping structure, and the female joint 401 and the male joint 402 are detachably connected through the clamping structure, and the female joint 401 and the male joint 402 are respectively connected to the first pipe (or the second pipe) and the water supply pipe (or water supply pipe); in this way, the device can be connected to the corresponding iced part of the water supply pipe. The water supply pipe described above can be a separately carried water storage bag or a fixed-point water station; in addition, before connecting the water supply pipe, hot water should be used to pour and / or knock to discharge the icicles of 600mm-800mm at the pipe end to reserve the initial water heating chamber.

[0045] On the other hand, the female end connector 401 and the male end connector 402 are connected by a clamping structure, and the clamping structure has a clamping position and a release position, so that the first pipe and the water supply pipe, and the second pipe and the water supply pipe can be connected or interrupted; when the clamping structure is in the clamping position, the water supply pipe, the first tube body 2, the water storage tank 1, the second tube body 3 and the water supply pipe are connected in sequence to form a first path. At this time, the high-temperature and high-pressure water in the water storage tank 1 is gradually transported to the water supply pipe through the first path. The high-temperature and high-pressure water can be used to melt the surface of the icicle in the pipe temporarily, so that the gap between the icicle and the inner wall of the pipe is filled with water, reducing the friction with the pipe wall so that the icicle slides out of the pipe, so as to achieve the purpose of unblocking the pipe and reduce the time cost of water use; after the operation is completed, the device is disconnected from the water supply pipe and the water supply pipe to form an independent second path. Of course, the first tube body 2 and the water inlet, and the second tube body 3 and the water outlet can also be connected by the joint assembly 4.

[0046] Therefore, the above-mentioned thawing device adopts the following steps:

[0047] Step 1: Survey and divide into sections: According to the on-site pipeline layout and icing conditions, divide the pipeline into several small sections. The dividing points should be selected at the elbows, reducers, branches, valves, etc. The length should be selected according to the above table;

[0048] Step 2: Connect the joint: Use the joint assembly 4 to connect the first pipe and the water supply pipe, and the second pipe and the water supply pipe; before disconnecting and connecting the water supply pipe, it is necessary to remove the icicles at the pipe ends;

[0049] Step 3, heating and pressurizing: turn on the power, turn on the booster pump to fill the water storage tank 1 with water, and the pressure value can be 0.1Mpa; turn off the booster pump, turn on the heating rod and raise the temperature to 60℃, turn on the booster pump again to raise the pressure in the pipe to 0.6Mpa, and observe the changes in the water temperature and pressure values ​​on the display screen. When the water temperature drops to 10℃ or below or the pressure drops to 0.1Mpa or below, turn on the corresponding function to increase the temperature and pressure, and repeat this process to maintain the water temperature at 60℃ and the pressure at 0.6Mpa, so that the icicles in the pipe are continuously peeled off from the pipe wall under high temperature and high pressure until icicles continue to slide out of the pipe (of course, as mentioned above, the water storage tank 1 can be kept warm and pressurized before or after the external water supply pipe is connected);

[0050] Step 4: Clean and connect the pipes: When no icicles slide out of the pipes, flush them continuously with running water until all icicles are completely discharged, disconnect the device, and check again along the pipes to discharge residual water in low-lying points to prevent re-freezing. Repeat the above steps to thaw and clear ice from the remaining frozen pipe sections, then restore the connections section by section, and resume water supply after completing the slow-freezing measures.

[0051] This device can solve the thawing problem of the entire water column of the DN20-DN200 PE water supply pipe after freezing. In winter, the outdoor temperature is lower than the freezing point of natural water bodies. Considering the heat dissipation rate of the pipe and the heating and pressurizing power of the thawing device, the length of the thawing pipe of the device should not be too long. Its length is less than the length of the pipe position where the water body is located when the temperature of the initial inlet water body drops to zero degrees and the heat dissipation rate is equal to the heating rate. This position is related to the ambient temperature and the contact surface area between the frozen body in the pipe and the high-temperature and high-pressure water.

[0052] This embodiment injects high-temperature and high-pressure clean water into the frozen pipe; the high-temperature water can cause the pipe to expand due to heat, thus improving its ductility. At the same time, the high-temperature and high-pressure water can temporarily melt the surface of the icicle in the pipe, so that the gap between the icicle and the inner wall of the pipe is filled with water, reducing the friction with the pipe wall so that the icicle slides out of the pipe, thereby achieving the purpose of unblocking the pipe and reducing the time cost of water use. This not only solves the problem of water supply pipes being easily frozen in winter in complex environments, but also provides an efficient, energy-saving, safe and easy-to-operate solution, which has significant technical advantages and social and economic benefits.

[0053] like Figure 2 , Figure 4 and Figure 5As shown, in one embodiment, the clamping structure includes a plurality of clamping portions 403 and a plurality of matching portions 405, and the plurality of clamping portions 403 are respectively and alternately arranged on the matching surfaces of the female end connector 401 and the male end connector 402, and the plurality of matching portions 405 are respectively and alternately arranged on the matching surfaces of the female end connector 401 and the male end connector 402, and the plurality of clamping portions 403 and the plurality of matching portions 405 are arranged in a one-to-one correspondence, and the clamping portion 403 is provided with a clamping groove 404 for rotating and clamping into the corresponding matching portion 405. Specifically, in order to achieve the detachable connection between the female connector 401 and the male connector 402, the present embodiment defines a snap-fit ​​structure including a plurality of snap-fit ​​parts and a plurality of mating parts 405. The plurality of snap-fit ​​parts and the plurality of mating parts 405 are arranged one by one at the mating surfaces of the female connector 401 and the male connector 402, and the snap-fit ​​parts on different mating surfaces are staggered. Similarly, the mating parts 405 on different mating surfaces are also staggered. In this way, the sealing and connection tightness of the two mating surfaces can be improved. Furthermore, an arc-shaped slot 404 is provided on the inner surface of the holding part 403. Rotating the corresponding connector can make the mating part 405 snap into the slot 404. The operation is simple and quick. Of course, the above-mentioned two mating surfaces can also be provided with corresponding sealing structures to block the gap after the two mating surfaces are connected, so as to further improve the sealing. Figure 5 As shown, the female connector 401 and the male connector 402 are provided with corresponding threaded structures for connecting corresponding pipes; alternatively, the corresponding pipes can be connected by hot-melt connection, but the hot-melt connection may involve the problem of inconvenience in subsequent disassembly, and the corresponding pipes need to be cut, which can be selected according to the installation needs.

[0054] Furthermore, if Figure 5 As shown, in one embodiment, the matching portion 405 has a long section 406 and a short section 407 extending in different directions, one end of the long section 406 is connected to one end of the short section 407, and the long section 406 can be inserted into the clamping groove 404, so that the short section 407 abuts against and is exposed to the corresponding clamping portion 403. Specifically, in order to effectively connect the clamping portion 403 and the matching portion 405, and avoid the natural separation of the two without the action of external force; this embodiment defines that the matching portion 405 has a long section 406 and a short section 407, and the long section 406 and the short section 407 are integrally formed to form a similar L-shaped structure, so that the long section 406 can be inserted into the above-mentioned clamping groove 404, and the short section 407 is used to limit the corresponding clamping portion 403. At the same time, the setting of the short section 407 can limit the rotation direction of the female end connector 401 and the male end connector 402, so as to avoid the loosening of the connector and the pipeline caused by the rotation of the corresponding connector.

[0055] Furthermore, if Figure 5As shown, in one embodiment, a notch 408 is provided between the adjacent holding portions 403 and the matching portions 405. Specifically, since the female end connector 401 and the male end connector 402 are connected in a rotating manner, and the components are arranged in a staggered manner, in order to facilitate the long section 406 of each matching portion 405 to be clamped in each clamping groove 404; in this embodiment, a notch 408 is provided between the corresponding holding portion 403 and the matching portion 405, and the notch 408 can avoid the corresponding holding portion 403, so as to facilitate the effective connection of the two connectors.

[0056] like Figure 2 , Figure 3 As shown, in one embodiment, at least one of the two connector assemblies 4 is provided with an elastic connection assembly 5, and the elastic connection assembly 5 includes a bellows 501 and a clamp 502. One end of the bellows 501 is connected to the male connector 402, and the other end is used to connect the water supply pipe or the water supply pipe, and the connection between the two is fixed by the clamp 502. Specifically, in order to adapt to pipes of different sizes; this embodiment is provided with an elastic connection assembly 5 to improve the sealing performance between the male connector 402 and the external pipe; this embodiment is described by taking the second pipe as an example; the elastic connection assembly 5 includes a bellows 501 and a clamp 502. The bellows 501 can be connected to the male connector 402 on the one hand, and can be easily changed on the other hand. The bending path and the port can be expanded due to its certain toughness, so that it can adapt to the installation position of the on-site pipeline to prevent the occurrence of connection dead angles. Furthermore, the connection between the bellows 501 and the external pipe is locked by the clamp 502, thereby improving the tightness and sealing of the connection to prevent water leakage. Of course, the connection between the bellows 501 and the male end connector 402 can also be fixed by the same clamp 502.

[0057] Furthermore, if Figure 3 As shown, in one embodiment, the end of the bellows 501 away from the male end connector 402 is provided with a plurality of elastic folds 503 at intervals, and the clamp 502 is sleeved outside the plurality of elastic folds 503. Specifically, in order to further meet the installation and connection requirements of different sizes; in this embodiment, an elastic fold 503 is provided at the end of the bellows 501, so that the end has a certain elasticity, which is used to expand or shrink the port, so as to facilitate the connection of pipes of different sizes.

[0058] like Figure 2As shown, in one embodiment, the thawing device also includes a storage assembly 6, the storage assembly 6 includes a mounting base 601 provided on the water storage tank 1, and a first support frame 602 and a second support frame 603 respectively rotatably provided at different positions of the mounting base 601, the first support frame 602 and the second support frame 603 are independently arranged with each other, and both are respectively connected to the first tube body 2 and the second tube body 3, so as to synchronously or asynchronously link the first tube body 2 and the second tube body 3 to move closer to or away from each other under the action of external force. Specifically, in order to facilitate the storage of corresponding pipes when not in use and to facilitate the use of different connection angles; this embodiment is provided with a storage component 6, which includes a mounting seat 601, a first support frame 602 and a second support frame 603, the mounting seat 601 is arranged on the water tank 1, and the first support frame 602 and the second support frame 603 can be rotated relative to the mounting seat 601, and the two support frames are independently arranged with each other; under the action of external force, the two support frames can respectively drive the first pipe and the second pipe to rotate to a suitable angle; by changing the distance between the two pipes, the two pipes can be stored and effectively connected with other pipes.

[0059] Furthermore, if Figure 2 As shown, in one embodiment, the storage assembly 6 further includes a linkage structure, which includes a first link 604 and a second link 605 hinged at the same position of the mounting seat 601, and the first link 604 and the second link 605 are respectively movably connected to the first support frame 602 and the second support frame 603. Specifically, in order to constrain and drive the first support frame 602 and the second support frame 603 to move; in this embodiment, the first link 604 and the second link 605 are respectively arranged at the two support frames, so that one end of the two links are hinged at the same position of the mounting seat 601, and the other ends of the two links are respectively movably connected to the two support frames; in this way, the distance between the first support frame 602 and the second support frame 603 can be changed by adjusting the angle between the first link 604 and the second link 605; at the same time, the stability of the corresponding support frame can be improved during operation.

[0060] Furthermore, if Figure 2 As shown, in one embodiment, the first support frame 602 and the second support frame 603 are both provided with a guide groove 7 for sliding the first connecting rod 604 and the second connecting rod 605, respectively. Specifically, in order to constrain the moving path of each connecting rod, thereby limiting the moving path of each support frame; in this embodiment, a guide groove 7 is provided in the length direction of each support frame, so that the corresponding connecting rod can slide into the guide groove 7. Of course, the guide groove 7 in this embodiment has a rotation angle, and when the connecting rod is located at the rotation angle, the support frame moves to the maximum opening and closing position.

[0061] Furthermore, if Figure 1, Figure 2 As shown, in one embodiment, the water storage tank 1 is provided with a storage box 8, and the mounting seat 601 can rotate relative to the storage box 8, so that the storage assembly 6, the first pipe and the second pipe can be folded or unfolded in the storage box 8. Specifically, in order to store each pipe and the storage assembly 6; this embodiment is provided with a storage box 8 on the surface of the water storage tank 1, the storage box 8 is an open structure, and the mounting seat 601 is rotatably arranged at the storage box 8; in this way, the mounting seat 601 can be turned forward and reversed to make the connection on it folded inside the storage box 8 or unfolded outside the storage box 8. At the same time, since the first support frame 602 and the second support frame 603 can adjust the distance between them under the action of external force, the footprint of the corresponding components can be further reduced in the above-mentioned folded state. In addition, in order to facilitate connection, the length of the pipe is generally set to be longer. In order to facilitate the flexible movement of the various components in the storage assembly 6, this embodiment provides a cavity in the first support frame 602 and the second support frame 603 to partially accommodate the first pipe and the second pipe, and the other part can be fixed to the storage box 8 or the water tank 1 by a rope.
