Description

Technical Field

[0001] This utility model relates to the field of shallow geothermal equipment, and more specifically, it relates to a transmission pipe isolation component for shallow geothermal applications. Background Technology

[0002] Shallow geothermal energy refers to the thermal energy with exploitable value stored in rock, soil, groundwater, and surface water at a certain depth (generally within 200 meters) below the Earth's surface. It primarily originates from solar radiation and heat conduction within the Earth's interior, making it a renewable energy source. Through energy exchange via technologies such as ground source heat pumps, the underground temperature field can recover within a certain timeframe and will not be depleted due to long-term use.

[0003] Isolation components for delivery pipelines can divide the pipeline into different areas or sections for flow control, pressure regulation, maintenance, and other operations. However, after long-term use, the sealing performance of the valve plate in the isolation component deteriorates, resulting in a decrease in the valve's isolation performance. At this point, each shift will be unable to isolate the water source, requiring the valve plate to be replaced. However, in existing devices, when the valve is replaced, the water source cannot be isolated due to valve failure, leading to a significant waste of water resources. Therefore, it is necessary to redesign a shallow geothermal delivery pipeline isolation component to address the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a shallow geothermal transmission pipe isolation assembly.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A shallow geothermal transmission pipe isolation assembly includes a transmission pipe body. An isolation groove is formed on the outer wall of the transmission pipe body. Two symmetrically arranged movable grooves are formed on the inner side wall of the isolation groove. A valve plate is slidably engaged within the isolation groove. A sliding groove is formed on the valve plate, and a sealing device is slidably connected within the sliding groove. The output end of the sealing device is connected to the two movable grooves respectively. A rotating groove is formed on the inner bottom wall of the isolation groove. Two symmetrically arranged locking slots are formed on the inner wall of the rotating groove, and the output end of the sealing device is slidably engaged within the two locking slots. A limiting groove is formed on the bottom wall of the rotating groove, and the output end of the sealing device extends into the limiting groove. An installation shell is fixedly installed on the outer wall of the transmission pipe body. A cover plate is fixedly installed on the upper surface of the installation shell. A driving device is provided on the cover plate, and the output end of the driving device passes through the cover plate and connects to the upper surface of the valve plate.

[0007] like Figure 1-5As shown, the specific implementation method is as follows: by setting up a driving device, valve plate, isolation groove and other devices, the driving device can drive the valve plate to rise and fall in the isolation groove. The rising and falling of the valve plate can isolate the water source in the conveying pipe body. By setting up a sealing device, limiting groove, rotating groove, moving groove and other devices, the limiting block can be made to abut against the inner top wall of the limiting groove by rotating the fixed shaft, so that the sealing plate can be fixed. Then, the sealing plate can be used to continue to isolate the water source in the conveying pipe body, avoiding the leakage and waste of water resources.

[0008] In a preferred embodiment, the sealing device includes a slider that is slidably engaged in a groove. A fixed shaft is rotatably connected inside the slider. The lower end face of the fixed shaft extends into a limiting groove and is fitted with two limiting blocks. The two limiting blocks are slidably connected to two slots respectively. A sealing plate is fixedly installed on one side of the slider. Movable blocks are fixedly installed on both sides of the sealing plate, and the two movable blocks are slidably engaged in corresponding movable grooves respectively.

[0009] In a preferred embodiment, a handle is fixedly mounted on the upper end face of the fixed shaft.

[0010] In a preferred embodiment, the diameter of the limiting groove is larger than the diameter of the rotating groove.

[0011] In a preferred embodiment, the drive device includes a mounting bracket, which is fixedly mounted on the upper end face of the cover plate. A hydraulic telescopic cylinder is fixedly mounted on the mounting bracket. The output shaft of the hydraulic telescopic cylinder passes through the cover plate and extends to be mounted on a connecting shaft. The lower end face of the connecting shaft is fixedly connected to the upper end face of the valve plate.

[0012] In a preferred embodiment, the slider is a T-block, and the groove is a T-groove that mates with the T-block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up a driving device, valve plate, partition groove and other devices, can use the driving device to drive the valve plate to rise and fall in the partition groove, and can use the rise and fall of the valve plate to isolate the water source in the conveying pipe body.

[0015] 2. This utility model, by setting up a sealing device, a limiting groove, a rotating groove, a moving groove, etc., allows the limiting block to abut against the inner top wall of the limiting groove by rotating the fixed shaft, so that the sealing plate can be fixed. In this way, the sealing plate can be used to further isolate the water source in the conveying pipe body, thus avoiding the leakage and waste of water resources.

[0016] In summary, this utility model is simple to operate. The driving device can drive the valve plate to rise and fall in the partition groove, and the water source in the conveying pipe body can be isolated by the rise and fall of the valve plate. In the event that the valve plate fails and needs to be replaced, the sealing device can continue to isolate the water source in the conveying pipe body, thus avoiding leakage and waste of water resources.

Detailed Implementation

[0023] 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.

[0024] Reference Figure 1-5A shallow geothermal transmission pipe isolation assembly includes a transmission pipe body 1. An isolation groove 13 is formed on the outer wall of the transmission pipe body 1. Two moving grooves 14 are symmetrically formed on the inner side wall of the isolation groove 13. A valve plate 7 is slidably engaged in the isolation groove 13. A sliding groove 17 is formed on the valve plate 7. A sealing device is slidably connected in the sliding groove 17. The output end of the sealing device is connected to the two moving grooves 14 respectively. A rotating groove 10 is formed on the inner bottom wall of the isolation groove 13. Two locking grooves 12 are symmetrically formed on the inner wall of the rotating groove 10. The output end of the sealing device is slidably engaged in the two locking grooves 12. A limiting groove 11 is formed on the bottom wall of the rotating groove 10. The output end of the sealing device extends into the limiting groove 11. An installation shell 5 is fixedly installed on the outer wall of the transmission pipe body 1. A cover plate 2 is fixedly installed on the upper end face of the installation shell 5. A driving device is provided on the cover plate 2. The output end of the driving device passes through the cover plate 2 and is connected to the upper end face of the valve plate 7.

[0025] like Figure 1-5 As shown, the specific implementation method is as follows: by setting up a driving device, valve plate 7, isolation groove 13 and other devices, the driving device can drive the valve plate 7 to rise and fall in the isolation groove 13. The rising and falling of the valve plate 7 can be used to isolate the water source in the conveying pipe body 1. By setting up a sealing device, limiting groove 11, rotating groove 10, moving groove 14 and other devices, the limiting block 16 can be made to abut against the inner top wall of the limiting groove 11 by rotating the fixed shaft 15, so that the sealing plate 18 can be fixed. Then, the sealing plate 18 can be used to continue to isolate the water source in the conveying pipe body 1, avoiding the leakage and waste of water resources.

[0026] The sealing device includes a slider 8, which is slidably locked in a groove 17. A fixed shaft 15 is rotatably connected inside the slider 8. The lower end face of the fixed shaft 15 extends into a limiting groove 11 and is fitted with two limiting blocks 16. The two limiting blocks 16 are slidably connected to two slots 12 respectively. A sealing plate 18 is fixedly installed on one side of the slider 8. Movable blocks 19 are fixedly installed on both sides of the sealing plate 18. The two movable blocks 19 are slidably locked in corresponding movable grooves 14. In the event of valve plate 7 failure, the sealing plate 18 can be used to isolate the water source in the conveying pipe body 1.

[0027] A handle 9 is fixedly installed on the upper end face of the fixed shaft 15.

[0028] The diameter of the limiting groove 11 is larger than the diameter of the rotating groove 10. It should be noted that this design allows the limiting block 16 to rotate within the limiting groove 11.

[0029] The drive device includes a mounting frame 3, which is fixedly mounted on the upper surface of the cover plate 2. A hydraulic telescopic cylinder 4 is fixedly mounted on the mounting frame 3. The output shaft of the hydraulic telescopic cylinder 4 passes through the cover plate 2 and extends to be mounted on a connecting shaft 6. The lower end face of the connecting shaft 6 is fixedly connected to the upper end face of the valve plate 7. The extension and retraction of the hydraulic telescopic cylinder 4 can drive the connecting shaft 6 and the valve plate 7 to extend and retract synchronously, thereby allowing the valve plate 7 to isolate the water source in the conveying pipe body 1.

[0030] The slider 8 is a T-shaped block, and the slide groove 17 is a T-shaped groove that mates with the T-shaped block. It should be noted that this design prevents the slider 8 from easily disengaging from the slide groove 17.

[0031] When this utility model is in use, the hydraulic telescopic cylinder 4 can be activated. The output shaft of the hydraulic telescopic cylinder 4 can drive the connecting shaft 6 to move up and down synchronously. The connecting shaft 6 can drive the valve plate 7 to isolate the water source in the conveying pipe body 1. At the same time, the sealing device will not detach from the slide groove 17 without the interference of external forces.

[0032] When the valve plate 7 needs to be replaced after long-term use, the cover plate 2 can be opened, then the sealing plate 18 can be pressed down, and the valve plate 7 can be lifted. At this time, under the sliding connection between the slider 8 and the slide groove 17, the slider 8 will disengage from the slide groove 17, and the valve can then be replaced. At the same time, turn the handle 9, and the handle 9 will drive the fixed shaft 15 to rotate synchronously. The fixed shaft 15 will drive the two limit blocks 16 fixed at its bottom to rotate. At this time, the two limit blocks 16 will rotate into the limit groove 11 and abut against the inner top wall of the limit groove 11. At this time, by using the limit block 16 to abut against the inner top wall of the limit groove 11, the fixed shaft 15 and the sealing plate 18 can be fixed and limited, so that the sealing plate 18 will not drive the moving block 19 to disengage from the moving groove 14. After the valve plate 7 is replaced, the slide groove 17 can be aligned with the slider 8, and then the slider 8 and the slide groove 17 will engage. After engagement, the handle 9 can be rotated again so that the handle 9 can drive the fixed shaft 15 and the two limit blocks 16 to rotate synchronously, so that the two limit blocks 16 are aligned with the two slots 12. At this time, the replacement of the valve plate 7 is completed.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
