Description

Technical Field

[0001] This invention belongs to the field of water well antifreeze technology, and relates to a heat preservation and antifreeze device, particularly a heat preservation and antifreeze device for circulating hot water in deep wells at high altitudes. Background Technology

[0002] Due to the influence of climate and geological conditions in the permafrost region of the plateau, deep groundwater often exists in the thawed soil layer below the lower limit of the permafrost layer, mainly in the form of confined water or fissure water. In the application of artificial well drilling for water extraction, there is a risk that the positive-temperature groundwater will rise along the well pipe and the outlet pipe into the permafrost layer and freeze.

[0003] Especially when water usage is low, the free water level in the well pipes and outlet pipes remains in the permafrost layer for extended periods due to groundwater pressure. Under the influence of sub-zero temperatures, the well pipes and outlet pipes are highly susceptible to freezing and blockage. Therefore, groundwater extraction in high-altitude permafrost regions requires anti-freezing control measures for the well pipes and outlet pipes. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a deep well hot water circulation insulation and antifreeze device for high-altitude areas. The technical problem this invention aims to solve is: how to achieve efficient insulation and antifreeze of deep wells using hot water circulation.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A deep well hot water circulation insulation and antifreeze device for high-altitude areas includes a water well, an electric boiler, and a tripod. A circulating water pipe is fixed at the inlet and outlet of the electric boiler and is located inside the water well. A manual winch is installed on the tripod, and a steel wire rope is installed on the manual winch. The steel wire rope is connected to the circulating water pipe through a connector. The circulating water pipe has a U-shaped structure, and a stainless steel counterweight is connected to the U-shaped bend of the circulating water pipe.

[0007] The working principle of this invention is as follows: During installation, assemble the various components of the water-circulating electric boiler at the designated installation location, and check the sealing and connection stability of each connection point. Start the assembled water-circulating electric boiler for trial operation, and test the control performance of each electrical device and the operating performance of the hot water boiler. Check for oil or water leaks at the joints of each component. Connect the tripod to each component at the wellhead according to the equipment instructions and check its stability. Check the braking and lifting functions of the manual winch to ensure they are normal. Then, simultaneously lower the circulating water pipe and wire rope into the well. Turn on the electric boiler, allowing hot water to circulate through the circulating water pipe in the well, thereby heating the inside of the well and achieving heat preservation and antifreeze.

[0008] The connector includes a double pipe clamp and a wire rope clamp. Both ends of the double pipe clamp are clamped onto the circulating water pipe. The wire rope is connected to the wire rope clamp, and the wire rope clamp is connected to the double pipe clamp by bolts.

[0009] The above structure facilitates the connection and fixation of the circulating water pipe and the wire rope, and also makes it easy to separate the circulating water pipe from the wire rope after pulling it out later.

[0010] A horizontal plate is fixed on the tripod, and a guide wheel is provided on the lower side of the horizontal plate. The steel wire rope is slidably connected to the guide wheel, and the other end of the horizontal plate is connected to the ground through a support rod.

[0011] The above structure allows the triangular wheel to be offset from the well, providing sufficient operating space when connecting the circulating water pipe and wire rope and lowering them into the well.

[0012] The well is equipped with a sealed cover at the top, and the sealed cover has a pumping pipe inlet and a circulating water pipe inlet.

[0013] The above structure not only allows for the sealing of the well with a cover, reducing the impact of external factors on the well, but also provides protection when connecting the circulating water pipe and steel wire rope. This not only prevents workers from accidentally falling into the well, but also reduces the probability of connecting parts falling into the well due to improper operation, thus improving work safety.

[0014] The circulating water pipe inlet has cavities on both the left and right sides, and springs are fixed inside the cavities. A sliding plate is fixed to the other end of the spring, and a baffle is installed on the sliding plate.

[0015] With the above structure, when the circulating water pipe is lowered into the well, the distance between the two baffles can be appropriately increased to ensure sufficient descent space. After the circulating water pipe is lowered, the baffles return to their original position to ensure a sealing effect on the well.

[0016] The upper end of the cavity is provided with a sliding groove, and a sliding rod is fixed on the sliding plate. The sliding rod passes through the sliding groove and extends out of the closed cover. A positioning mechanism is provided on the closed cover, and the sliding rod is connected to the positioning mechanism.

[0017] With the above structure, after the baffle is pulled open using the sliding rod, the baffle is positioned using the positioning mechanism, which facilitates operation.

[0018] The positioning mechanism includes a positioning plate, which is fixedly connected to the closed cover. A guide groove is provided on the positioning plate. A telescopic rod is fixed on the slide rod. The telescopic rod passes through the guide groove and is fixed to a fixing plate. A tension spring is fixed between the fixing plate and the slide rod. A handle is fixed on the fixing plate. A fixing block is fixed on the other side of the fixing plate. Two rows of fixing grooves corresponding to the fixing blocks are provided on the positioning plate.

[0019] With the above structure, when the baffle needs to be opened, the handle pulls the fixing block on the fixing plate out of the fixing groove, and then the telescopic rod drives the sliding rod to move, thereby realizing the movement of the baffle. After moving to the designated position, the handle is released, and under the action of the tension spring, the fixing block enters the corresponding fixing groove.

[0020] A connecting seat is fixed on the slide plate. A connecting groove is provided on the connecting seat. The lower end of the connecting groove is closed. A connecting block is fixed on the baffle. A rotating groove is provided in the connecting groove. A rotating shaft is rotatably connected in the rotating groove. The rotating shaft is fixedly connected to the connecting block. A torsion spring is sleeved on the rotating shaft. The two ends of the torsion spring are fixedly connected to the rotating groove and the connecting block, respectively.

[0021] With the above structure, when it is necessary to pull the circulating water pipe away from the well, the baffle can be pushed open by the connecting parts and circulating water pipe during the pulling process, so that the circulating water pipe can be pulled out smoothly without any additional operation, which is simple and convenient.

[0022] Compared with existing technologies, this deep well hot water circulation insulation and antifreeze device for high-altitude areas has the following advantages:

[0023] 1. During installation, assemble all components of the water-circulating electric boiler at the designated installation location, and check the sealing and stability of each connection point. Start the assembled water-circulating electric boiler for trial operation, and test the control performance of each electrical device and the operating performance of the hot water boiler. Check for oil or water leaks at the joints of each component. Connect the tripod to each component at the wellhead according to the equipment instructions and check its stability. Check the braking and lifting functions of the manual winch to ensure they are normal. Then, lower the circulating water pipe and wire rope into the well simultaneously, and then turn on the electric boiler to allow hot water to circulate through the circulating water pipe in the well, thereby heating the inside of the well and achieving heat preservation and antifreeze.

[0024] 2. The horizontal plate and guide wheel are designed to offset the triangular wheel from the well, providing sufficient operating space when connecting the circulating water pipe and wire rope and lowering them into the well.

[0025] 3. The installation of the sealing cover and baffles can be used to seal the water well, reducing the impact of the external environment on the water well and also reducing heat loss. When the circulating water pipe is lowered into the water well, the distance between the two baffles can be appropriately increased to ensure sufficient descent space. After the circulating water pipe is lowered, the baffles return to their original positions to ensure the sealing effect of the water well.

[0026] 4. The baffle and torsion spring are designed so that when the circulating water pipe needs to be pulled away from the well, the baffle can be pushed open by the connecting parts and circulating water pipe during the pulling process, so that the circulating water pipe can be pulled out smoothly without any additional operation, which is simple and convenient.

[0035] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0036] like Figures 1-7 As shown, this embodiment provides a deep well hot water circulation insulation and antifreeze device for high-altitude areas, including a water well 1, an electric boiler 2, and a tripod. A circulating water pipe 30 is fixed at the inlet and outlet of the electric boiler 2. The circulating water pipe 30 is located inside the water well 1. A manual winch is installed on the tripod 3. A steel wire rope 4 is installed on the manual winch. The steel wire rope 4 is connected to the circulating water pipe 30 through a connector 5. The circulating water pipe 30 has a U-shaped structure, and a stainless steel counterweight is connected to the U-shaped bend of the circulating water pipe 30.

[0037] During installation, assemble all components of the water-circulating electric boiler 2 at the designated installation location, and check the sealing and connection stability of each connection point. Start the assembled water-circulating electric boiler 2 for trial operation, and test the control performance of each electrical device and the operating performance of the hot water boiler. Check for oil or water leaks at the joints of each component. Connect the tripod 3 to each component at the wellhead of the water well 1 according to the equipment instructions and check its stability. Check the braking and lifting functions of the manual winch to ensure they are normal. Then, simultaneously lower the circulating water pipe 30 and the wire rope 4 into the well. Turn on the electric boiler 2, allowing hot water to circulate through the circulating water pipe 30 in the water well 1, thereby heating the inside of the water well 1 and achieving heat preservation and antifreeze.

[0038] The connector 5 includes a double pipe clamp 31 and a wire rope clamp 32. Both ends of the double pipe clamp 31 are clamped onto the circulating water pipe 30. The wire rope 4 is connected to the wire rope clamp 32. The wire rope clamp 32 and the double pipe clamp 31 are connected by bolts.

[0039] The above structure facilitates the connection and fixation of the circulating water pipe 30 and the steel wire rope 4, and also makes it easy to separate the circulating water pipe 30 from the steel wire rope 4 after pulling it out later.

[0040] A horizontal plate 6 is fixed on the tripod, and a guide wheel 7 is provided on the lower side of the horizontal plate 6. The steel wire rope 4 is slidably connected to the guide wheel 7, and the other end of the horizontal plate 6 is connected to the ground through a support rod.

[0041] The above structure allows the triangular wheel to be offset from the water well 1, providing sufficient operating space when connecting the circulating water pipe 30 and the steel wire rope 4 and lowering them into the water well 1.

[0042] The upper end of the well 1 is provided with a closed cover 8, and the closed cover 8 has a water pumping pipe inlet 9 and a circulating water pipe inlet 10.

[0043] The above structure not only allows the well 1 to be sealed with the cover 8, reducing the impact of external factors on the well 1, but also provides protection when connecting the circulating water pipe 30 and the wire rope 4. This not only prevents workers from accidentally falling into the well 1, but also reduces the probability of the connector 5 falling into the well 1 due to improper operation, thus improving work safety.

[0044] A cavity 11 is provided on both the left and right sides of the circulating water pipe inlet 10. A spring 12 is fixed inside the cavity 11. A slide plate 13 is fixed to the other end of the spring 12. A baffle 15 is provided on the slide plate 13.

[0045] With the above structure, when the circulating water pipe 30 is lowered into the well 1, the distance between the two baffles 15 can be appropriately increased to ensure sufficient descent space. After the circulating water pipe 30 is lowered, the baffles 15 return to their original position to ensure a sealing effect on the well 1.

[0046] The upper end of the cavity 11 is provided with a slide groove 16, and a slide rod 17 is fixed on the slide plate 13. The slide rod 17 passes through the slide groove 16 and extends out of the closed cover 8. A positioning mechanism is provided on the closed cover 8, and the slide rod 17 is connected to the positioning mechanism.

[0047] With the above structure, after the baffle 15 is pulled open using the slide bar 17, the baffle 15 is positioned using the positioning mechanism, which facilitates operation.

[0048] The positioning mechanism includes a positioning plate 18, which is fixedly connected to the closed cover 8. A guide groove is provided on the positioning plate 18. A telescopic rod 19 is fixed on the slide rod 17. The telescopic rod 19 passes through the guide groove and is fixed to a fixing plate 21. A tension spring 20 is fixed between the fixing plate 21 and the slide rod 17. A handle 22 is fixed on the fixing plate 21. A fixing block 23 is fixed on the other side of the fixing plate 21. Two rows of fixing grooves 24 corresponding to the fixing blocks 23 are provided on the positioning plate 18.

[0049] With the above structure, when the baffle 15 needs to be opened, the fixing block 23 on the fixing plate 21 is pulled out of the fixing groove 24 by the handle 22, and then the sliding rod 17 is moved by the telescopic rod 19, thereby realizing the movement of the baffle 15. After moving to the designated position, the handle 22 is released, and under the action of the tension spring 20, the fixing block 23 enters the corresponding fixing groove 24.

[0050] A connecting seat 14 is fixed on the slide plate 13. A connecting groove 25 is provided on the connecting seat 14. The lower end of the connecting groove 25 is closed. A connecting block 26 is fixed on the baffle 15. A rotating groove 27 is provided in the connecting groove 25. A rotating shaft 28 is rotatably connected in the rotating groove 27. The rotating shaft 28 is fixedly connected to the connecting block 26. A torsion spring 29 is sleeved on the rotating shaft 28. The two ends of the torsion spring 29 are fixedly connected to the rotating groove 27 and the connecting block 26, respectively.

[0051] With the above structure, when it is necessary to pull the circulating water pipe 30 away from the well 1, the baffle 15 can be pushed open by the connecting piece 5, the circulating water pipe 30 and other components during the pulling process, so that the circulating water pipe 30 can be pulled out smoothly without any additional operation, which is simple and convenient.

[0052] The working principle of this invention is as follows: During installation, assemble all components of the water-circulating electric boiler 2 at the designated installation location, and check the sealing and connection stability of each connection point. Then, start the assembled water-circulating electric boiler 2 for trial operation, and test the control performance of each electrical device and the operating performance of the hot water boiler. Check for oil or water leaks at the joints of each component. At the wellhead of the water well 1, connect the tripod 3 to each component according to the equipment instructions and check its stability. Check the braking and lifting functions of the manual winch to ensure they are normal, and then cover it with the sealing cover 8. Furthermore, by pulling the handle 22, the fixing block 23 on the fixing plate 21 is pulled out of the fixing groove 24, and then the sliding rod 17 is moved by the telescopic rod 19, thereby realizing the movement of the baffle 15. After moving to the designated position, the handle 22 is released, and under the action of the tension spring 20, the fixing block 23 enters the corresponding fixing groove 24. Then, the circulating water pipe 30 and the steel wire rope 4 are simultaneously lowered into the well. Then, the electric boiler 2 is turned on, so that hot water circulates in the water well 1 through the circulating water pipe 30, thereby heating the inside of the water well 1 and achieving heat preservation and antifreeze.

[0053] In summary, by setting up structures such as the electric boiler 2, circulating water pipe 30, and tripod 3, the deep well can be efficiently insulated and protected from freezing using hot water circulation.
