Description

Technical Field

[0001] The invention belongs to the technical field of heat exchange devices, and in particular relates to an inner-wing heat exchange structure for extracting geothermal energy without interference. Background Art

[0002] Non-interference geothermal energy (also known as closed geothermal system or closed-loop geothermal system) is a technology that utilizes the heat from the earth's interior, but unlike traditional geothermal energy development methods, it does not directly exploit groundwater or steam, but extracts heat from deep underground through a closed circulation system. This method aims to reduce the impact on the environment and improve energy efficiency through a completely closed pipeline network, usually composed of pipes made of high-density polyethylene (HDPE) or other corrosion-resistant materials, which are buried deep underground. The fluid in the pipeline (usually water or ethylene glycol solution) circulates, absorbs the heat from the ground and returns to the ground for heating or power generation. Because it does not involve the exploitation and discharge of groundwater, it can significantly reduce the impact on the groundwater environment and avoid the pollution problems that may occur in traditional geothermal energy development.

[0003] In order to improve the heat exchange efficiency, fins are often installed around the tubes to increase the heat exchange area. After long-term use, impurities in the groundwater will adhere to the fins, resulting in a decrease in the thermal conductivity of the fins. Since the fins are deep underground, it is difficult to clean the fins. Therefore, with the increase in usage time, the heat exchange efficiency of the heat exchange device gradually decreases, which is not conducive to the exploitation of geothermal energy. At the same time, since the fins and heat exchange tubes are often arranged in an interlaced manner, the fins are divided into multiple small spaces, making the fins difficult to clean. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide an inner fin heat exchange structure for extracting geothermal energy without interference.

[0005] The technical solution adopted to solve the above technical problems is: an inner fin heat exchange structure for extracting geothermal energy without interference, comprising a shell, a heat exchange mechanism is fixedly connected inside the shell, a driving mechanism is fixedly connected to one side of the shell, a plurality of pushing mechanisms are arranged on the driving mechanism, and a cleaning mechanism is fixedly connected to each of the pushing mechanisms; The driving mechanism comprises a screw rod penetrating through a rotatably connected housing, a connecting frame is threadedly connected through the screw rod, a first motor is fixedly connected to the upper surface of the housing, and an output end of the first motor is fixedly connected to the screw rod; The pushing mechanism includes a shell fixedly connected to the connecting frame, a transmission shaft rotatably connected through the shell, a second motor fixedly connected to one side of the shell, an output end of the second motor fixedly connected to the transmission shaft, a plurality of connecting blocks slidably connected in the shell, and a pair of connecting plates rotatably connected between the plurality of connecting blocks.

[0006] Through the above technical scheme, the fins can be automatically cleaned by using the driving mechanism, the pushing mechanism and the cleaning mechanism, so as to avoid a large amount of dirt accumulation on the surface of the fins after long-term use, which affects the heat exchange efficiency of the fins. The underground hot water is driven through the fins by the first fan blade and the second fan blade to heat the water in the heat exchange tube, thereby extracting geothermal energy without interference. Through the use of the second motor, several pushing mechanisms can drive the cleaning mechanisms into the gaps of the fins at the same time, which greatly improves the cleaning efficiency and can effectively solve the obstruction problem caused by several heat exchange tubes passing through the fins.

[0007] Furthermore, a first pipe is fixedly connected to one side of the shell, a first fixing frame is fixedly connected inside the first pipe, a first fan blade is arranged on the first fixing frame, a second pipe is fixedly connected to the side of the shell away from the first pipe, a second fixing frame is fixedly connected inside the second pipe, and a second fan blade is arranged on the second fixing frame.

[0008] Through the above technical solution, the rotation of the first fan blade drives the underground hot water into the outer shell through the first pipe, and the rotation of the second fan blade drives the underground hot water to be discharged from the outer shell through the second pipe, so that the underground hot water continuously passes through the fins. The flow rate of the underground hot water can be increased by the first fan blade and the second fan blade, thereby improving the heat exchange efficiency of the fins, avoiding the underground hot water from not flowing in the outer shell during the heat exchange operation, resulting in a drop in temperature and affecting the heat exchange efficiency. At the same time, the flowing underground hot water can delay the time when impurities adhere to the surface of the fins, greatly improving the service life.

[0009] Furthermore, the heat exchange mechanism includes a plurality of heat exchange tubes passing through a fixedly connected outer shell, a plurality of fins are fixedly connected to each of the heat exchange tubes, one end of the heat exchange tube is fixedly connected to a water inlet main pipe, an upper end of the water inlet main pipe is fixedly connected to a water inlet flange, an end of the heat exchange tube away from the water inlet main pipe is fixedly connected to a water outlet main pipe, and an end of the water outlet main pipe away from the heat exchange tube is fixedly connected to a water outlet flange.

[0010] Through the above technical scheme, the water circulation device can be connected through the water inlet flange and the water outlet flange, so that water enters the heat exchange tube through the water inlet main pipe, and is discharged through the water outlet main pipe after being heated by the fins in the heat exchange tube to complete the heat exchange. During the whole cycle, the liquid in the heat exchange tube does not contact the underground hot water, thereby greatly reducing the pollution of the underground hot water. Through the use of the water inlet main pipe and the water outlet main pipe, the heat exchange tubes can be connected, the interfaces required for the heat exchange mechanism can be reduced, and the overall sealing can be improved. Through the use of the water inlet flange and the water outlet flange, the disassembly and assembly of the heat exchange mechanism can be facilitated.

[0011] Furthermore, a pair of sliding rods are fixedly connected inside the shell, and the sliding rods penetrate and are slidably connected to a connecting frame.

[0012] Through the above technical solution, the first motor drives the screw rod to rotate, and the screw rod cooperates with the connecting frame to drive the pushing mechanism to rise and fall, so that the pushing mechanism can drive the cleaning mechanism to rise and fall, so that the cleaning mechanism can move between fins at different heights to clean the fins. Through the use of the sliding rod, the connecting frame can be prevented from tilting and getting stuck, which greatly improves the stability of the connecting frame.

[0013] Furthermore, a slide groove is provided in the shell, the connecting block is slidably connected to the slide groove, both ends of the connecting block are fixedly connected with protrusions, both ends of the connecting block are provided with first grooves corresponding to the protrusions, the protrusions and the first grooves are engaged with each other, and the connecting plate is located on the upper side of the connecting block.

[0014] Through the above technical scheme, the connection block can be accommodated through the setting of the slide groove to avoid occupying too much lateral space, thereby reducing the required hole diameter and greatly reducing the construction cost. The setting of the first groove and the protrusion can avoid axial rotation of the connection block, improve the stability of the cleaning mechanism during movement, and avoid the cleaning mechanism from rotating axially and bumping against the fins. At the same time, the locking effect of the first groove and the protrusion can greatly improve the stability of the pushing mechanism, avoid bending between the connection blocks, and cause the cleaning mechanism to scratch and damage the fins.

[0015] Furthermore, one end of a pair of connecting plates is penetrated and fixedly connected with a first connecting roller, one end of a pair of connecting plates away from the first connecting roller is penetrated and fixedly connected with a second connecting roller, the second connecting roller is penetrated and rotatably connected with a connecting block, the first connecting roller is penetrated and rotatably connected with a connecting block, the connecting blocks and connecting plates are arranged alternately, and a plurality of driving gears are penetrated and rotatably connected on the transmission shaft, and the driving gears are respectively engaged with the first connecting roller and the second connecting roller.

[0016] Through the above technical solution, the second motor drives the driving gear to rotate, and the driving gear drives the connecting block to move through the first connecting roller and the second connecting roller. Since the connecting plate is located on one side of the connecting block, the chain composed of the connecting blocks can only bend to one side and the other side cannot be bent, so that the cleaning mechanism can be pushed between the fins to facilitate the cleaning of the fins.

[0017] Furthermore, the cleaning mechanism includes a fixed shell fixedly connected to the connecting block, a third motor is fixedly connected inside the fixed shell, an output end of the third motor is fixedly connected to a fixed shaft, an end of the fixed shaft away from the third motor is fixedly connected to a driving gear, driven gears are provided on both sides of the driving gear, and the driving gear and the driven gear are meshed with each other.

[0018] Through the above technical solution, the third motor drives the driving gear to rotate, and the driving gear drives the multifunctional driven gear to rotate. Since the fixed shafts are all eccentrically arranged, the rotating shaft on the driven gear drives the moving plate to make reciprocating motion up and down and left and right, while driving the brush head to rotate, so that the upper and lower surfaces of the fins can be cleaned, avoiding impurities from adhering to the surface of the fins and affecting heat exchange.

[0019] Furthermore, the driving gear and the driven gear are fixedly connected to a fixed shaft on one side close to the third motor, and the fixed shaft is located at an eccentric position of the driving gear and the driven gear. The fixed shaft and the fixed shell are rotatably matched, and the driven gear is fixedly connected to a rotating shaft at a center position on a side away from the fixed shaft. A second groove is provided on the fixed shell, and a movable plate is movably connected in the second groove. The rotating shaft passes through the rotatably connected movable plate, and a brush head is fixedly connected to one end of the rotating shaft away from the driven gear.

[0020] Through the above technical solution, by using the second groove and the movable plate, the movable plate can only move up, down, left and right in the second groove, and cannot move axially along the rotating shaft. The stability of the brush head during movement can be improved and the axial movement of the brush head can be avoided. By setting the fixed shaft, the driving gear can drive the driven gear to rotate, so that the center of the driven gear can move back and forth up, down, left and right.

[0021] The beneficial effects of the present invention are as follows: (1) The present invention uses a driving mechanism, and the first motor drives the screw to rotate. The screw and the connecting frame cooperate to drive the pushing mechanism to move up and down, so that the pushing mechanism can drive the cleaning mechanism to move up and down, so that the cleaning mechanism can move between fins at different heights to clean the fins; (2) The present invention uses a pushing mechanism, and the second motor drives the driving gear to rotate. The driving gear drives the connecting block to move through the first connecting roller and the second connecting roller. Since the connecting plate is located on one side of the connecting block, the chain composed of the connecting block can only bend to one side, and the other side cannot be bent, so that the cleaning mechanism can be pushed between the fins, which is convenient for cleaning the fins. At the same time, due to the setting of multiple pushing mechanisms, the cleaning efficiency of the fins is greatly improved; (3) The present invention uses a cleaning mechanism, and the third motor drives the driving gear to rotate. The driving gear drives the multifunctional driven gear to rotate. Since the fixed shaft is eccentrically set, the rotating shaft on the driven gear drives the moving plate to make reciprocating motion up and down and left and right, and drives the brush head to rotate, so that the upper and lower surfaces of the fins can be cleaned, and impurities are prevented from adhering to the fin surface and affecting heat exchange.

The use of the slide bars 34 can prevent the connecting frame 33 from tilting, thereby improving the stability of the connecting frame 33 .

[0028] like Figure 7-Figure 9 As shown, a plurality of pushing mechanisms 4 are arranged on the driving mechanism 3, and the pushing mechanism 4 includes a shell 41 fixedly connected to the connecting frame 33, a transmission shaft 43 is rotatably connected through the shell 41, a second motor 42 is fixedly connected to one side of the shell 41, and an output end of the second motor 42 is fixedly connected to the transmission shaft 43, a plurality of connecting blocks 45 are slidably connected in the shell 41, and a pair of connecting plates 48 are rotatably connected between the plurality of connecting blocks 45, and the second motor 42 drives the transmission shaft 43 to rotate. Since the connecting plate 48 is located on one side of the connecting block 45, the connecting block 45 can only bend to one side, and the cleaning mechanism 5 is driven into the gap of the fin 21 through the continuous extension of the connecting block 45.

[0029] A slide groove 44 is provided in the shell 41, and the connecting block 45 is slidably connected to the slide groove 44. Both ends of the connecting block 45 are fixedly connected with protrusions 46. Both ends of the connecting block 45 are provided with first grooves 47 corresponding to the protrusions 46. The protrusions 46 and the first grooves 47 are engaged with each other. The connecting plate 48 is located on the upper side of the connecting block 45. The connecting block 45 is accommodated by the slide groove 44 to avoid occupying too much space and improve the overall space utilization. The mutual engagement of the protrusions 46 and the first grooves 47 can avoid axial rotation of the connecting block 45 and improve the stability of the cleaning mechanism 5 when moving.

[0030] One end of a pair of connecting plates 48 passes through and is fixedly connected with a first connecting roller 49, and one end of a pair of connecting plates 48 away from the first connecting roller 49 passes through and is fixedly connected with a second connecting roller 410, the second connecting roller 410 passes through and is rotatably connected with a connecting block 45, the first connecting roller 49 passes through and is rotatably connected with a connecting block 45, the connecting blocks 45 and the connecting plates 48 are arranged alternately, and a plurality of driving gears 411 pass through and are rotatably connected with the transmission shaft 43, the driving gears 411 are respectively engaged with the first connecting roller 49 and the second connecting roller 410, the transmission shaft 43 drives the driving gears 411 to rotate, and the driving gears 411 are engaged with the first connecting roller 49 and the second connecting roller 410, thereby driving the connecting plates 48 to move, and the connecting plates 48 drive the connecting blocks 45 to move.

[0031] like Figure 10-13 As shown, a plurality of pushing mechanisms 4 are fixedly connected with a cleaning mechanism 5, and the cleaning mechanism 5 includes a fixed shell 51 fixedly connected to the connecting block 45, and a third motor 52 is fixedly connected in the fixed shell 51, and an output end of the third motor 52 is fixedly connected with a fixed shaft 58, and an end of the fixed shaft 58 away from the third motor 52 is fixedly connected with a driving gear 55, and a driven gear 56 is arranged on both sides of the driving gear 55, and the driving gear 55 and the driven gear 56 are meshed with each other. The third motor 52 drives the fixed shaft 58 on the driving gear 55 to rotate. Since the fixed shaft 58 is located at the eccentric shaft of the driving gear 55 and the driven gear 56, the driving gear 55 drives the driven gear 56 to rotate, and at the same time, the driven gear 56 drives the rotating shaft 59 located at the center to reciprocate left and right and up and down.

[0032] A fixed shaft 58 is fixedly connected to one side of the driving gear 55 and the driven gear 56 close to the third motor 52. The fixed shaft 58 is located at an eccentric position of the driving gear 55 and the driven gear 56. The fixed shaft 58 and the fixed shell 51 rotate in cooperation. A rotating shaft 59 is fixedly connected to the center position of one side of the driven gear 56 away from the fixed shaft 58. A second groove 53 is provided on the fixed shell 51. A movable plate 54 is movably connected in the second groove 53. The rotating shaft 59 penetrates and rotates through the movable plate 54. A brush head 57 is fixedly connected to one end of the rotating shaft 59 away from the driven gear 56. The brush head 57 is driven by the driven gear 56 to reciprocate left and right and up and down while rotating, so that the upper and lower surfaces of the fin 21 can be fully cleaned. By using the second groove 53 and the movable plate 54, the stability of the brush head 57 during movement can be improved, and the axial movement of the brush head 57 can be avoided.

[0033] The working principle of this embodiment is as follows: the underground hot water is driven to enter the housing 1 through the first pipe 6 by the rotation of the first fan blade 8, and the underground hot water is driven to be discharged from the housing 1 through the second pipe 9 by the rotation of the second fan blade 11, so that the underground hot water continuously passes through the fins 21, and the water circulation device is connected through the water inlet flange 24 and the water outlet flange 26, so that the water enters the heat exchange tube 22 through the water inlet main pipe 23, and is discharged through the water outlet main pipe 25 after being heated by the fins 21, so that the heat exchange is completed. When the fins 21 need to be cleaned, the first motor 31 drives the screw rod 32 to rotate, and the screw rod 32 cooperates with the connecting frame 33 to drive the connecting frame 33 to move up and down along the sliding rod 34, thereby driving the pushing mechanism 4 to move up and down, so that the cleaning mechanism 5 is aligned with the gap between the fins 21; The second motor 42 is started, and the second motor 42 drives the transmission shaft 43 to rotate, and the transmission shaft 43 drives the driving gear 411 to rotate, and the driving gear 411 engages with the first connecting roller 49 and the second connecting roller 410, thereby driving the connecting plate 48 to move, and the connecting plate 48 drives the connecting block 45 to move. Since the connecting plate 48 is located on one side of the connecting block 45, the connecting block 45 can only bend to one side, and the cleaning mechanism 5 is driven to enter the gap of the fin 21 through the continuous extension of the connecting block 45. The axial rotation of the connecting block 45 is avoided by the mutual engagement of the protrusion 46 and the first groove 47, thereby improving the stability of the cleaning mechanism 5 when moving; Afterwards, the third motor 52 drives the fixed shaft 58 on the driving gear 55 to rotate. Since the fixed shaft 58 is located at the eccentric shaft of the driving gear 55 and the driven gear 56, the driving gear 55 drives the driven gear 56 to rotate while the driven gear 56 drives the rotating shaft 59 located at the center to move back and forth left and right and up and down, thereby driving the brush head 57 to move back and forth left and right and up and down while rotating on its own, and can fully clean the upper and lower surfaces of the fin 21. By using the second groove 53 and the movable plate 54, the stability of the brush head 57 during the movement can be improved, and the axial movement of the brush head 57 can be avoided.
