Description

Technical Field

[0001] The present invention mainly relates to the field of geothermal heat exchange and storage equipment, and specifically, it is a geothermal heat storage pressure balance heat exchange device. Background Art

[0002] In traditional geothermal heat storage heat transfer systems, heat transfer liquids are usually used as heat transfer media to transfer the heat of the heat source to the solid-liquid phase change material to store heat, and then the heat exchange device exchanges heat with the solid-liquid phase change material to release heat: the cold heat transfer liquid exchanges heat with the heat source to obtain the hot heat transfer liquid, and the hot heat transfer liquid flows to the solid-liquid phase change material under the action of the heat transfer liquid pump to exchange heat with it. The solid-liquid phase change material absorbs and stores heat, and the solid-liquid phase change material exchanges heat with the heat-consuming equipment to release heat. The hot heat transfer liquid is further input into the heat exchange device for functions such as residential heating and then undergoes a reflux cycle. In this process, due to the unstable temperature of the geothermal heat source, it is easy to cause unstable temperature and pressure inside structures such as heat exchange pipes, which in turn causes the heat exchange and storage system to operate unstably. Moreover, in general heat exchange structures, the solid-liquid phase change heat exchange material is closely attached to structures such as heat exchange pipes, resulting in continuous heat exchange. Under unstable states of structures such as heat exchange pipes, it is easy to cause material damage and thus affect the stability of the equipment. Summary of the Invention

Furthermore, when the geothermal heat exchange temperature is relatively low, the heating can be preferentially ensured to be sufficient while pausing the heat storage, ensuring the stable heat supply under the condition of relatively low temperature and pressure of the equipment; 2. Further setting a rotatable and fixed track ring structure enables the cold heat transfer structure and the hot heat transfer structure to be driven by the power device to rotate and approach inside the track ring structure. Furthermore, when the temperature of the geothermal heat source is too high, by bringing the cold heat transfer structure and the hot heat transfer structure close to and fit with each other for heat conduction, the temperature and pressure inside the hot heat transfer structure can be stabilized, and cooperating with reducing or stopping the liquid pumping speed can quickly reduce the pressure inside the equipment to prevent the equipment pressure from being unstable; 3.

Moreover, it is possible to control the separation of the heat exchange mechanism from the phase change heat storage material when the latter is in the heat release functional state and continue to cooperate with other phase change heat storage materials. As a result, the heat release of the phase change heat exchange material is more thorough during heat release, enhancing the heat release efficiency of the phase change heat storage material and its subsequent heat storage efficiency.

[0016] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0017] Please refer to Figures 1-14, a geothermal heat storage pressure balance heat exchange device, comprising a device housing 10, a rotating ring mechanism 20, a heat exchange and heat storage mechanism 30, a power device 40, and a positioning device 50. Two groups of the rotating ring mechanisms 20 are rotatably arranged on the upper and lower sides inside the device housing 10 and are fixedly connected to each other. The heat exchange and heat storage mechanism 30 is arranged inside the rotating ring mechanism 20 and is slidably connected thereto. The power device 40 is arranged on the top of the device housing 10 and cooperates with the heat exchange and heat storage mechanism 30 to drive it to move relative to the rotating ring mechanism 20. The positioning device 50 is fixedly arranged around the top of the device housing 10 and can be inserted and cooperated with the rotating ring mechanism 20. The heat exchange and heat storage mechanism 30 includes an orbital rotation mechanism 60 and a heat exchange and heat storage plate structure 70. The orbital rotation mechanism 60 is arranged inside the rotating ring mechanism 20 and is rotatably connected thereto and can be driven by the power device 40. The heat exchange and heat storage plate structure 70 is arranged at the bottom of the orbital rotation mechanism 60 and is driven by it to perform a specific movement.

[0018] The above working principle: The heat exchange and heat storage plate structure 70 is connected to the heat supply structure and the geothermal heat exchange structure to form a liquid cycle for heat exchange with the geothermal energy and supply heat to residents or heating equipment. Further, a phase change heat exchange material is arranged inside the device housing 10, so that the heat exchange and heat storage plate structure 70 can be in contact and cooperation with the phase change heat exchange material, and then the phase change heat exchange material can store heat. Further, the power device 40 drives the track rotation mechanism 60 to rotate in a circle, so that the heat exchange and heat storage plate structure 70 can rotate inside the device housing 10, and then the heat exchange and heat storage plate structure 70 can be driven to rotate, so that the heat exchange and heat storage plate structure 70 can change the rotation position to perform uniform heat exchange and heat storage operations on the phase change heat storage materials around the inside of the device housing 10. And the heat release can be made more thorough by changing the rotation angle of the heat exchange and heat storage plate structure 70 to make a certain side of the phase change heat storage material out of the heat exchange and heat storage state for heat release operation, and avoid heat release loss caused by heat release into the heat exchange and heat storage plate structure 70. Further, by separating the phase change heat storage materials, the heat exchange and heat storage plate structure 70 can rotate to the position of the separation gap, and then the device can pause the heat storage operation, which is applicable to the situation of low geothermal temperature to ensure that the internal temperature and pressure can stably supply heat to the heating equipment. Further, the rotation ring mechanism 20 is fixed by the positioning device 50 provided. Subsequently, the power device 40 can drive the track rotation mechanism 60 and the heat exchange and heat storage plate structure 70 to rotate and approach inside the rotation ring mechanism 20. The liquid inlet heat exchange plate 701 and the heat storage heat exchange plate 702 included in the heat exchange and heat storage plate structure 70 are inserted and matched by approaching, so that the two perform mutual heat exchange operations. The heat transfer liquid inside the heat storage heat exchange plate 702 conducts heat to the cold heat transfer liquid entering the liquid inlet heat exchange plate 701, so that the heat inside the heat storage heat exchange plate 702 is reduced, and further the unstable operation of the equipment caused by the too high temperature and pressure of the heat storage heat exchange plate 702 when the local geothermal heat is too high is balanced.

[0019] For specific reference Figures 1-4 , the device housing 10 includes a support pipe 101, a phase change heat storage block 105, and a positioning hole 106.

The phase change heat storage blocks 105 are fixedly and densely arranged at equal intervals around the support pipe 101, around the circular hole 103 opened on the upper support plate 102.

[0020] In this embodiment, the device is supported by the support tube 101. The rotation ring mechanism 20 can be installed inside the rotation track ring 104 through the setting of the rotation track ring 104 for rotation. Further, the phase change heat storage block 105 is provided for cooperating with the heat exchange and heat storage plate structure 70 to perform the phase change heat storage operation. By arranging multiple groups at equal intervals on one side, the heat exchange and heat storage plate structure 70 can be inserted into the gap for heat storage operation to improve efficiency. Further, the phase change heat storage blocks 105 are respectively arranged around the inside of the support tube 101, so that they can be rotated by the heat exchange and heat storage plate structure 70 for heat storage operations respectively, and gaps are left between each group to pause the heat exchange and heat storage operation.

A spring sleeve rod 208 is fixedly provided inside one side of the roller rod 206. The spring sleeve 209 is sleeved on the outer periphery of the spring sleeve rod 208 and is rotationally connected thereto. A spring support rod groove 2010 is opened on one side of the spring sleeve rod 208. A spring support plate one 2011 is fixedly provided on the outer periphery of the front part of the spring sleeve rod 208.

It is opened at the upper parts of both ends of the track ring 201 provided at the upper part.

[0022] In this embodiment, by arranging the track ring 201 inside the rotating track ring 104, the heat exchange and heat storage mechanism 30 can be arranged inside it for orbital rotation. Further, by arranging the roller rod 206 and the roller 207 to abut against the rotating track ring 104, and the first spring 2012 supports the spring support rod 2014 to pull the spring rod 2013 to move inside the spring sleeve 209, thereby making the spring rod 2013 and the spring sleeve 209 contract relatively, further driving the roller rod 206 to move inward, and then controlling the roller 207 to always abut against the rotating track ring 104, so as to ensure that the track ring 201 always remains stable. Further, by arranging the connecting rod 203 to connect and support the track rings 201 arranged on the upper and lower sides, it can keep synchronous rotation and stable support inside the device housing 10.

[0023] Specifically refer to Figures 1-3 As shown in FIGS. 5-7, the track rotation mechanism 60 includes a spring roller support plate 601, a track roller 605, and a connecting pipe sleeve 606. The spring roller support plate 601 is arranged on both sides inside the track ring 201. A plurality of spring roller rods 602 are fixedly arranged inside the spring roller support plate 601 and are slidably connected thereto. The inner end of the spring roller rod 602 is fixedly provided with a second spring support plate 603. The upper part of the second spring support plate 603 is fixedly provided with a second spring 604 sleeved on the outer periphery of the spring roller rod 602 and abutting against the spring roller support plate 601. The track roller 605 is arranged at the end of the spring roller rod 602 and is rotatably connected thereto and is installed inside the track ring 201 for rotational connection therewith. The connecting pipe sleeve 606 is fixedly arranged on both sides of the spring roller support plate 601. Forked liquid pipes 607 are fixedly arranged inside both spring roller support plates 601. A guide ring 608 is fixedly arranged on the outer periphery of the upper part of the upper forked liquid pipe 607.

[0024] In this embodiment, by arranging the track roller 605 inside the track ring 201, it drives the spring roller support plate 601 to move and rotate inside the track ring 201. Further, since the spring roller support plate 601 has a certain arc, each track roller 605 generates an arc so that each track roller 605 can be fixed on the arc parts on both sides of the track ring 201. Further, the spring roller rod 602 can move inside the spring roller support plate 601 and is pulled and limited by the second spring 604 for each track roller 605, so that the spring roller support plate 601 can move into the parallel part of the track ring 201.

[0025] Specifically refer to Figures 1-3, 5, 13 - 14, the heat exchange and heat storage plate structure 70 includes a liquid inlet heat exchange plate 701 and a heat storage heat exchange plate 702. Multiple groups of the liquid inlet heat exchange plates 701 are interconnected and connected to the bifurcated liquid pipes 607 on one side. Multiple groups of the heat storage heat exchange plates 702 are interconnected and connected to the bifurcated liquid pipes 607 on one side.

[0026] In this embodiment, the liquid inlet heat exchange plate 701 is used to introduce cold heat transfer liquid and transfer it into the geothermal heat exchange structure for heat exchange and heat storage operations to form hot heat transfer liquid. Subsequently, it further enters the heat storage heat exchange plate 702 to cooperate with the phase change heat storage block 105 for heat storage. Then, it carries the waste heat into the heating equipment for subsequent heating heat exchange and cooling operations and enters the device again for heat exchange cycle. The liquid inlet heat exchange plate 701 is a structure extending inwards, so that it does not contact the phase change heat storage block 105 and can take out the heat inside the phase change heat storage block 105, but can contact the heat storage heat exchange plate 702 to perform temperature reduction and pressure reduction operations on it. The heat storage heat exchange plate 702 is a structure extending to both sides, so that it can cooperate with the phase change heat storage block 105 for heat exchange and heat storage operations and can cooperate with the liquid inlet heat exchange plate 701 for heat transfer and temperature reduction.

[0027] Specific reference Figures 1-3 , 12, the power device 40 includes a gear ring 401, a rotating ring 403, and a rotating track rod 407. The gear ring 401 is fixedly arranged on the upper part of the support pipe 101. The outer circumference of the gear ring 401 is provided with teeth 402. The rotating ring 403 is sleeved inside the gear ring 401 and is rotatably connected to it. One side of the rotating ring 403 is fixedly provided with a servo motor support plate 404. The upper part of the servo motor support plate 404 is fixedly provided with a servo motor 405. The output end of the servo motor 405 penetrates through the servo motor support plate 404 and is rotatably connected to it. The output end of the servo motor 405 is fixedly provided with a gear 406 that meshes with the teeth 402. The rotating track rod 407 is fixedly arranged on both sides inside the rotating ring 403 and clamps the upper guide ring 608 and is slidably connected to it.

[0028] In this embodiment, the servo motor 405 rotates to drive the gear 406 to rotate, and then cooperates with the gear teeth 402 to control the rotation of the rotating ring 403 inside the gear ring 401, thereby driving the rotation of the rotating track rod 407. Further, the rotating track rod 407 clamps the guiding ring 608 to drive the overall rotation of the rotating ring mechanism 20 and the heat exchange and heat storage mechanism 30. At this time, the heat exchange and heat storage plate structure 70 includes a liquid inlet heat exchange plate 701 and a heat storage heat exchange plate 702, which are respectively arranged on both sides of the rotating ring mechanism 20, so that the heat storage heat exchange plate 702 can be inserted into the internal voids of the phase change heat storage block 105 for heat exchange and heat storage operations, and can be rotated to different positions by the power device 40 to perform heat exchange and heat storage operations on the phase change heat storage blocks 105 at different positions around. Further, the heat storage heat exchange plate 702 can be rotated into the voids between the phase change heat storage blocks 105 to pause the heat exchange and heat storage operations.

[0029] Specifically refer to Figures 1-4 , the positioning device 50 includes a positioning electric push rod 501, which is arranged at a position corresponding to the positioning hole 106 and fixedly connected to the support plate 102. The telescopic end of the positioning electric push rod 501 is fixedly provided with an insertion rod 502 that can be inserted into the positioning insertion hole 2015.

[0030] In this embodiment, first, the power device 40 drives the rotating ring mechanism 20 and the heat exchange and heat storage mechanism 30 to rotate to a certain position, so that the positioning jack 2015 coincides with the positioning hole 106. Further, the output end of the positioning electric push rod 501 extends to drive the insertion rod 502 to insert into the positioning jack 2015, so that the track ring 201 and the support plate 102 are relatively fixed. Further, the power device 40 can continue to drive the rotating ring mechanism 20 and the heat exchange and heat storage mechanism 30 to rotate. At this time, since the track ring 201 is fixed, the track rotating mechanism 60 is driven and moved to the parallel part inside the fixed track ring 201 through the defined cooperation between the guiding ring 608 and the rotating track rod 407. Further, the rotating track rod 407 rotates to a position perpendicular to the track ring 201, so that the track rotating mechanism 60 moves to the central position inside the track ring 201 and approaches each other. Further, it drives the liquid inlet heat exchange plate 701 and the heat storage heat exchange plate 702 to approach and be inserted and matched, so that the cold heat transfer liquid entering the liquid inlet heat exchange plate 701 contacts the hot heat transfer liquid with too high temperature inside the heat storage heat exchange plate 702, thereby balancing the overall temperature inside the device. After the balance is completed, the power device 40 drives the track rotating mechanism 60 to rotate back to both sides of the track ring 201 and makes the positioning electric push rod 501 contract, so that the heat storage heat exchange plate 702 can cooperate with the phase change heat storage block 105 again for heat exchange and heat storage operations.
