Description

Technical Field

[0001] This utility model relates to the field of geothermal pipeline laying technology, and in particular to a prefabricated geothermal well pipe connection kit. Background Technology

[0002] Geothermal energy is a technology that utilizes shallow geothermal resources for heating and cooling. In its implementation, heat exchange pipes are laid in the shallow layer of the earth's surface, with a heat exchange fluid circulating inside. This allows the fluid to exchange heat with the geothermal energy. Since the heat exchange fluid is mostly water, and the temperature after geothermal heat exchange is around 17 degrees Celsius, prolonged circulation of this water within the pipes can lead to the growth of microorganisms such as algae and fungi. Therefore, filtration devices are currently installed between indoor and underground heat exchange pipes to filter out algae and fungi.

[0003] However, since the buried heat exchange pipelines are connected by a connecting kit, the current structure of the connecting kit includes a large-diameter manifold and multiple connectors installed on the manifold. The multiple connectors are connected to the buried heat exchange pipeline, and the heat exchange fluid flows through the manifold. Therefore, a large number of microorganisms will also grow on the inner wall of the manifold. The method of setting up a filter device on the heat exchange pipeline cannot prevent the growth of microorganisms in the manifold, and a large amount of microbial slime will be deposited in the manifold, becoming the source of dirt growth in the entire heat exchange circulation pipeline.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0022] Please refer to Figure 1-4 The technical solution of this utility model is as follows: a prefabricated geothermal well pipe connection kit, including a collection pipe 1 and multiple joints 10 disposed on the side wall of the collection pipe 1. A scraper 4 is provided inside the collection pipe 1 for guidance. A drain outlet 12 is provided on the side wall of the collection pipe 1 near one end. A through hole 201 is provided on the end face of the other end of the collection pipe 1. The scraper 4 is detachably and fixedly connected to the other end of the collection pipe 1.

[0023] As a specific implementation method, refer to Figures 1-4 The specific technical solution of this application is as follows: It includes a manifold 1, which is generally a cylindrical pipe made of PE material. One end is provided with a first flange, and multiple connectors 10 are provided on the side wall. The multiple connectors 10 are evenly spaced along the axial direction. In actual use, the first flange is used to connect to the user end. A valve body such as a ball valve is provided between the first flange and the user end. A scraper 4 is provided inside the manifold 1. The scraper 4 is generally made of stainless steel, PE, or other materials, and has a circular plate structure, capable of sliding and guiding against the inner side wall of the manifold 1. In conjunction with the first flange plate 11, a drain port 12 is connected to the side wall of the manifold 1, and a control valve 13 is installed on the drain port 12. A through hole 201 is provided on the other end face of the manifold 1. During normal operation, the scraper 4 is fixed to the other end of the manifold 1, the through hole 201 is closed, the connector 10 is connected to the buried heat exchange pipe, and the control valve 13 is in the closed state. After a predetermined period of use, by closing the valve body connected to the first flange and the valve bodies on each connector 10, the through hole 201 is opened, and the control valve 13 is opened. (Refer to...) Figure 5A force-applying rod 5 is connected to the scraper 4 through the through hole 201, which pushes the scraper 4 to move. When the scraper 4 moves, it can push the microorganisms attached to the side wall of the collecting pipe 1 and the debris deposited in the collecting pipe 1 to be discharged from the drain port 12, thereby achieving the purpose of cleaning the inside of the collecting pipe 1. The force-applying rod 5 is a rod that can be detachably and fixedly connected to the scraper 4. For example, the rod is made of PE material. The user applies force to the force-applying rod 5 to drive the scraper 4 to move. After cleaning, the scraper 4 is pulled back to the initial position and fixed again. Then the control valve 13 is closed and the valve body connected to the first flange and the valve bodies on each joint 10 are opened for reuse. Through the above structure, the inside of the collecting pipe 1 can be cleaned regularly, improving the cleanliness of the inside of the collecting pipe 1, thereby improving the cleanliness of the entire heat exchange pipeline.

[0024] Furthermore, as a specific implementation method, refer to Figure 4 , Figure 6 , Figure 7 A groove 20 is provided on the end face of the other end of the collecting pipe 1. The groove 20 is coaxially arranged with the through hole 201. The scraper 4 is provided with a screw 40 extending out of the through hole 201. A first limiting surface is provided on one end of the screw 40 extending out of the through hole 201, and the first limiting surface faces the bottom surface of the groove 20. As a specific embodiment, the scraper 4 is provided with a screw 40 adapted to the through hole 201. The screw 40 can pass through the through hole 201, and then the first limiting surface is provided on the screw 40. The first limiting surface and the plate surface of the scraper 4 clamp and position the two ends of the through hole 201, thereby achieving the effect of fixing the scraper 4.

[0025] Furthermore, as a specific implementation method, refer to Figure 4 , Figure 6 , Figure 7 The screw 40 is threaded to a nut 41 at its end, and the first limiting surface is the end face of the nut 41. The axial dimension of the nut 41 is not greater than the axial dimension of the groove 20. Specifically, the screw 40 is threaded to a nut 41 at its end, which allows for a detachable fixed connection. The groove 20 on the end face of the manifold 1 can accommodate the nut 41, facilitating the installation of the second end plate 3.

[0026] Furthermore, as a preferred embodiment, refer to Figure 4 , Figure 5 The radius of the screw 40 is smaller than the radius of the through hole 201. Setting the radius of the screw 40 to be smaller than the radius of the through hole 201 allows for a threaded connection between the force-applying rod 5 and the screw 40. After connection, the radius of the force-applying rod 5 is controlled to match the radius of the through hole 201, ensuring that the force-applying rod 5 can guide and engage with the through hole 201, and also facilitating the connection between the force-applying rod 5 and the scraper 4.

[0027] Furthermore, as a preferred embodiment, refer to Figure 4 A second end plate 3 is detachably and fixedly connected to the end face of the other end of the collecting pipe 1. An annular first sealing element 31 is provided between the second end plate 3 and the end face of the other end of the collecting pipe 1, and the first sealing element 31 is arranged around the groove 20. Specifically, by providing the second end plate 3, the opening of the through hole 201 can be sealed, thus meeting the sealing requirements of the end of the collecting pipe 1.

[0028] Furthermore, as a specific implementation method, refer to Figure 6 , Figure 7 Unlike the through hole 201, the bottom of the groove 20 is provided with at least one communicating vent hole 202. It is understood that, referring to... Figure 5 When the scraper 4 is pushed by the force rod 5, the gas can enter the collecting pipe 1 in time through the connecting air hole 202 when the force rod 5 is in coordination with the through hole 201, which reduces the resistance received by the scraper 4 when it moves and facilitates the smooth sliding operation of the scraper 4.

[0029] Furthermore, as a preferred embodiment, a second flange plate 14 is provided at the other end of the manifold 1. The second flange plate 14 is detachably and fixedly connected to the first end plate 2. The through hole 201 and the groove 20 are eccentrically arranged with respect to the second flange plate 14. Specifically, the first flange plate 11 and the first end plate 2 are detachably and fixedly connected. The first flange plate 11 and the manifold 1 are coaxially provided with a step 21. By providing the step 21, it is convenient to open a groove 20 on the other side of the first flange plate 11. A second sealing element 22 is provided between the second flange plate 14 and the first end plate 2. The second end plate 3 and the first end plate 2 are detachably and fixedly connected. A first sealing element 31 is provided between the second end plate 3 and the first end plate 2, so that the end of the through hole 201 is sealed by the second end plate 3. By providing the first end plate 2, it is convenient to install and remove the scraper 4. By setting the through hole 201 and the first end plate 2 eccentrically, the screw 40 is fixedly connected to the scraper 4. When the screw 40 passes through the through hole 201 to install and remove the nut 41, the scraper 4 will not rotate at will, which is convenient for the removal and installation of the nut 41.

[0030] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
