Description

Technical Field

[0001] The present invention belongs to the technical field of energy utilization, and in particular relates to a method for regulating and controlling the storage of cold and heat energy for building new energy. Background Art

[0002] Influenced by solar radiation and the Earth's internal heat, soil has a temperature, and soil temperatures vary at different depths. Furthermore, soil temperature fluctuates periodically, as surface temperature fluctuates cyclically with the diurnal and seasonal variations in solar radiation. Each temperature cycle experiences a maximum and a minimum. As soil depth increases, the time of maximum and minimum temperature gradually increases. Furthermore, the annual variation in soil temperature decreases rapidly with increasing soil depth. Diurnal and annual variations in soil temperature are similar, with surface temperature variations being much greater than those in deeper layers. Furthermore, the diurnal variation curves for soil layers >20 cm are almost parallel, meaning that the diurnal variation in soil temperature is lower than the annual variation.

[0003] New soil energy storage technologies, leveraging the characteristics of soil temperature, have emerged, most notably in recent years with ground-source heat pumps. However, ground-source heat pumps are installed at a fixed depth and position, making modifications a significant engineering effort, equivalent to a complete reinstallation. This inevitably results in the surrounding soil releasing more heat than it absorbs, or vice versa, after a period of operation, causing thermal imbalance and impacting the efficiency of the ground-source heat pump. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: to overcome the shortcomings of the existing technology and provide a method for storing and controlling new energy heat and cold in buildings. The present invention can store the heat energy extracted in summer and the cold energy extracted in winter inside the soil, which is convenient for heating in winter and cooling in summer. At the same time, the depth of the energy storage pile can be freely adjusted to exchange heat with the soil in different depth areas, avoiding thermal imbalance of the soil caused by the fixed position, which affects the energy storage effect.

[0020] Preferably, a first clamping ring and a second clamping ring are respectively sleeved on the same position above the outer portion of the vertical tube and the extension rod.

[0021] The top surface of the surface platform is located outside the through hole and is distributed in a circular array with more than two anti-sinking rods. One end of the anti-sinking rod is hinged or rotatably connected to the surface platform, and the other end is provided with a hook with an opening greater than 120°. The opening of the hook faces upward, and the hook is matched with the first clamping ring or the second clamping ring.

[0022] The spiral soil energy storage device also includes a shifter, which includes a threaded pipe, a hydraulic cylinder, at least three columns and a connecting piece.

[0023] The columns are arranged in a circular array outside the vertical threaded pipe. A base plate is fixed under the columns, and the base plate is fixed to the top surface of the surface platform by bolts.

[0024] A sliding block which can slide up and down is sleeved on the column, and the sliding block is fixedly connected to the outer wall of the threaded pipe through an inclined rod.

[0025] The hydraulic cylinder is fixed on the top of the threaded pipe, the end of the piston rod of the hydraulic cylinder is arranged downward and extends into the interior of the threaded pipe, and the end of the piston rod is rotatably connected to the connecting piece.

[0026] The outer wall of the connecting piece is convexly provided with a thread, the connecting piece is threadedly connected to the threaded pipe, and the center of the bottom surface of the connecting piece is concave with a cylindrical inner cavity.

[0027] When in use, the inner cavity is sleeved above the vertical tube or the extension rod, and the connecting piece drives the vertical tube or the extension rod to move up and down while rotating.

[0028] Preferably, a mounting groove is recessed in the top surface of the surface platform, and the bottom plate is arranged inside the mounting groove.

[0029] Preferably, the side surface of the slider is threadedly connected with a positioning bolt, or two pins are inserted on the column. When the bottom surface of the slider contacts the bottom plate, the lower pin is located above the slider and contacts the top surface of the slider; when the slider slides to the top dead point, the upper pin is located below the slider and contacts the bottom surface of the slider.

[0030] Preferably, the inner cavity diameter is the same as the outer diameter of the vertical tube and the extension rod, and the bottom surface of the connecting piece is located outside the inner cavity and is provided with 1 to 3 cylindrical rods. The length of the cylindrical rods is greater than or equal to the thickness of the first clamping ring and the second clamping ring, and an arc plate is fixed at the bottom of the cylindrical rods.

[0031] The method for regulating and controlling building new energy cold and heat storage includes the following steps:

[0032] A. The surface platform is fixed on the ground, with its top surface not lower than the ground level, and the spiral tube is buried in the soil through the through hole;

[0033] B. When storing thermal energy: the heat source flows in through the liquid inlet main pipe, then flows into the interior of the spiral tube through each liquid inlet branch pipe, extension rod, and vertical pipe, heating the phase change tube inside. The phase change material inside the phase change tube absorbs the heat and undergoes phase change, storing the thermal energy. The heat source bypasses the first baffle and flows from the end of the spiral tube into another cavity, then flows along the vertical pipe, extension rod, and liquid return branch pipe into the interior of the liquid return main pipe, thus circulating.

[0034] C. When releasing heat energy: the cold source flows through the same path, enters the spiral tube to absorb the heat inside the phase change tube, and increases the temperature of the cold source;

[0035] D. When using soil temperature for temperature adjustment: In summer, the underground soil temperature is lower than the outdoor and indoor temperatures. The phase change tube contacts the spiral tube through the first partition to conduct heat, so that the temperature stored in the phase change tube is the same as the soil temperature. The circulating fluid flows into the spiral tube to cool it down, and then cools the room to adjust the indoor temperature.

[0036] In winter, the underground soil temperature is higher than the outdoor and indoor temperatures. The circulating fluid flows into the spiral tube to heat up the room, and then heats the room to adjust the indoor temperature.

[0037] E. Since the adjacent spiral tubes are arranged in a staggered manner, the distance between each spiral tube is long, which facilitates the utilization of the heat energy of the surrounding soil. By adjusting the opening and closing of the electric control valves on each liquid inlet branch pipe and liquid return branch pipe, each spiral tube is utilized in an orderly manner to avoid imbalance of the underground soil temperature layer;

[0038] F. Regularly adjust the height of each spiral tube to make full use of the soil heat energy. When the spiral tube is moved upward, fix the shifter, set the connector on the vertical tube, pass the arc plate through the first clamping ring, connect the hydraulic station to the hydraulic cylinder, and control the piston rod to move upward. When the piston rod moves upward, the connector rotates, and the arc plate rotates to the bottom of the radial connecting rod between the first clamping ring and the vertical tube, so that the connector moves upward and drives the vertical tube to move upward, and rotates synchronously. The outer side of the spiral tube is provided with a cutting surface, so that the upward movement during its rotation can reduce the resistance of the soil to it, making it easier for the spiral tube to move up and down;

[0039] When the spiral tube moves downward, remove the upper end cover above the vertical tube, fix the bottom of the extension rod to the vertical tube, then move the threaded tube upward, put the connecting piece on the top of the extension rod, and the piston rod pushes the spiral tube to rotate and move downward through the connecting piece.

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] (1) The height of the spiral tube of the energy storage pile can be adjusted up and down, which is convenient for energy exchange with soil at different depths. At the same time, it also effectively avoids the situation where the energy of the surrounding soil is saturated and the energy exchange efficiency is reduced when the position is fixed.

[0042] (2) The outer side of the spiral tube is provided with a cutting surface, making it similar to a screw as a whole. The up and down movement during the rotation process effectively reduces the resistance of the soil to it.

[0043] (3) A phase change tube filled with phase change material is provided inside the spiral tube, which uses the principle of phase change energy storage to store energy, thereby improving the energy density of the stored energy.

[0044] (4) The arrangement of spiral tubes buried underground can effectively increase the contact area with the soil and improve the energy exchange efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0066] The accompanying drawings are the best embodiments of the building new energy cold and heat storage and control method. The present invention will be further described in detail below with reference to the accompanying drawings.

[0067] The building new energy cold and heat storage control method is based on a spiral soil energy storage device. Figure 1 As shown, the spiral soil energy storage device includes a surface platform 1 and an energy storage pile.

[0068] The surface platform 1 is mounted on the ground, with its top surface no lower than ground level. It is constructed of steel or a concrete foundation to support the shifter. A number of through-holes 101 are arranged in a rectangular array on the surface platform 1, each corresponding to an energy storage stack. During installation, the surface platform 1 is secured, and the energy storage stack is then buried underground through the through-holes 101.

[0069] The energy storage stack includes a spiral tube 2 and a vertical tube 3 connected to the top of the spiral tube 2. The vertical tube 3 is fixedly connected to the spiral tube 2. The spiral tube 2 passes through a through hole 101 and is buried in the soil directly below the through hole 101. A first partition 202 is provided in the middle of the spiral tube 2. The first partition 202 is arranged along the spiral line at the center of the spiral tube 2. The first partition 202 divides the interior of the spiral tube 2 into two cavities. The two cavities are connected at the ends of the spiral tube 2.

[0070] At the same time, by the Figure 6 As shown, the spiral tube 2 rotates as it moves up and down, and a cutting surface 201 with a triangular cross-section is provided on the outside of the spiral tube 2, so that the cutting surface 201 can cut the soil during the rotation of the spiral tube 2, making the entire spiral tube 2 similar to a screw, reducing the resistance caused by the soil to it during its up and down movement.

[0071] A phase change tube 203 is positioned in the middle of the first partition 202. A phase change thermal storage material is placed inside the tube to increase energy storage density. The material can be paraffin wax or inorganic water and salt. The tube 203 is 80% to 90% filled with the material, leaving space for the material to undergo phase changes.

[0072] A second baffle 302 is positioned in the middle of the vertical tube 3, with the bottom of the second baffle 302 contacting the top of the first baffle 202. The second baffle 302 divides the interior of the vertical tube 3 into two independent first flow channels 303, each corresponding to the two cavities within the spiral tube 2. The upper end of the vertical tube 3 passes through the through hole 101 and is positioned above the surface platform 1.

[0073] By the attached Figure 7 As shown, a first groove 3021 for positioning is formed inwardly on the top surface of the second partition 302 , and a first threaded hole 3022 is provided at the bottom of the first groove 3021 .

[0074] The upper end of the vertical tube 3 is covered with an upper end cap 5, which is provided with a liquid inlet branch pipe 6 and a liquid return branch pipe 7. The liquid inlet branch pipe 6 and the liquid return branch pipe 7 are respectively connected to the two first flow channels 303. A positioning block 502 is protruding from the bottom surface of the upper end cap 5. The positioning block 502 is inserted into the first groove 3021 to define the position of the liquid inlet branch pipe 6 and the liquid return branch pipe 7. A fastening bolt 501 is passed through the center of the upper end cap 5 and is threadedly connected to the first threaded hole 3022.

[0075] The inner wall of the upper end cover 5 is provided with a rubber layer to improve the sealing between it and the vertical pipe 3.

[0076] Both the liquid inlet branch pipe 6 and the liquid return branch pipe 7 are equipped with electrically controlled valves 8. A liquid return main pipe 9 and a liquid inlet main pipe 10 are mounted on the surface platform 1. The liquid inlet branch pipe 6 is connected to the liquid inlet main pipe 10, and the liquid return branch pipe 7 is connected to the liquid return main pipe 9. The electrically controlled valves 8 are electrically connected to a control system that uses existing technology to control the opening and closing of each electrically controlled valve 8.

[0077] In order to avoid the soil area being small for heat energy exchange between two adjacent spiral tubes 2, the Figure 3 As shown, two adjacent spiral tubes 2 are arranged in a staggered manner, and an extension rod 4 is connected above the vertical tube 3 of the spiral tube 2 at the lower position.

[0078] The extension rod 4 is provided with a third partition 402 inside, and the top surface of the third partition 402 is concave with a second groove 4021, and the bottom surface of the second groove 4021 is provided with a second threaded hole 4022. The third partition 402 divides the interior of the extension rod 4 into two independent second flow channels 403, so that the structure inside and at the top of the extension rod 4 is the same as that of the vertical tube 3.

[0079] At the same time, by the Figure 10 And attached Figure 11 As shown, the lower end surface of the third partition 402 of the extension rod 4 is recessed with a slide groove 404. The slide groove 404 is located on the side wall of the extension rod 4 and has a through slideway. A screw 406 is fixed downwardly to the top surface of the slide groove 404. A clamping block 405 is provided inside the slide groove 404. The clamping block 405 has protruding edges 4051 on both sides. The protruding edges 4051 are slidably arranged inside the slideway of the side wall of the extension rod 4. A spring 407 is provided between the top surface of the clamping block 405 and the top surface of the slide groove 404.

[0080] To connect the extension rod 4 to the vertical tube 3, manually move the flange 4051 up and down, allowing the block 405 to overcome the thrust of the spring 407 and move into the chute 404. Then, align the screw 406 with the first threaded hole 3022 and threadably engage it. When the screw 406 reaches the bottom, release the flange 4051, and the block 405 is locked into the first groove 3021 under the thrust of the spring 407. The sealing effect at the connection between the extension rod 4 and the vertical tube 3 can be improved by using a rubber gasket, sealant, or by adding a sealing ring to a sealing groove recessed in the top surface of the vertical tube 3.

[0081] The vertical tube 3 and the extension rod 4 are respectively provided with a first clamping ring 301 and a second clamping ring 401 at the same position on the outside. The first clamping ring 301 and the second clamping ring 401 are respectively fixedly connected to the outer wall of the vertical tube 3 and the extension rod 4 through a plurality of radial connecting rods.

[0082] By the attached Figure 2 As shown, the top surface of the surface platform 1 is surrounded by two or more anti-sinking rods 11 arranged in a circular array around the through hole 101. One end of each anti-sinking rod 11 is hinged or pivotally connected to the surface platform 1, and the other end is provided with a hook with an opening greater than 120°, facing upward. The hook engages with the first clasp 301 or the second clasp 401. The anti-sinking rods 11 prevent the spiral tube 2 from moving downward due to geological changes.

[0083] The spiral soil energy storage device also includes a shifter used when adjusting the height of the spiral tube 2. Figure 12 To the attached Figure 16 As shown, the shifter includes a threaded tube 12 , a hydraulic cylinder 13 , at least three columns 14 and a connecting piece 15 .

[0084] The length of the threaded tube 12 is greater than that of the extension rod 4. To increase support stability, this embodiment utilizes four upright posts 14, arranged in a circular array outside the vertical threaded tube 12. A base plate 1401 is secured beneath the upright posts 14. The top surface of the surface platform 1 has a recessed mounting groove 102 with threaded holes at its bottom. The base plate 1401 is positioned within the groove and secured to the top surface of the surface platform 1 via bolts. To prevent the threaded holes from becoming clogged with dust when not in use, the mounting groove 102 is covered with a cover plate 103 when not in use.

[0085] A slider 1202 is mounted on the column 14, allowing it to slide up and down. Slider 1202 is fixedly connected to the outer wall of the threaded tube 12 via a diagonal rod 1201. To position slider 1202, a positioning bolt is threaded onto its side, or two latches 1402 are inserted into the column 14. When the bottom surface of slider 1202 contacts the base plate 1401, the lower latch 1402 is positioned above slider 1202 and contacts its top surface. When slider 1202 reaches its top dead center, the upper latch 1402 is positioned below slider 1202 and contacts its bottom surface. Latch 1402 can be removed while slider 1202 is sliding.

[0086] Hydraulic cylinder 13 is connected to the hydraulic station via hydraulic piping, which controls the up and down movement of piston rod 1301. Hydraulic cylinder 13 is secured to the top of threaded tube 12 via flanges and bolts. The end of piston rod 1301 of hydraulic cylinder 13 faces downward and extends into threaded tube 12. The end of piston rod 1301 passes through connector 15, which is equipped with a disc to prevent it from falling off. It is rotatably connected to connector 15 via the disc.

[0087] The connector 15 is located inside the threaded tube 12. The outer wall of the connector 15 is provided with a thread. The connector 15 is threadedly connected to the threaded tube 12. A cylindrical inner cavity 1501 is concave in the center of the bottom surface of the connector 15. The diameter of the inner cavity 1501 is the same as the outer diameter of the vertical tube 3 and the extension rod 4. Figure 19 As shown, the bottom surface of the connecting member 15, located outside the inner cavity 1501, is provided with one to three cylindrical rods 1502. The length of the cylindrical rods 1502 is greater than or equal to the thickness of the first and second snap rings 301, 401. An arcuate plate 1503 is fixed to the bottom of the cylindrical rods 1502. The arcuate plate 1503 can pass through the gap between the two connecting rods connected by the first and second snap rings 301, 401.

[0088] By the attached Figure 18 As shown, during use, the inner cavity 1501 is positioned over the vertical tube 3 or the extension rod 4. The cylindrical rod 1502 and the curved plate 1503 are inserted into the gap between the two connecting rods connected to the first or second clasps 301 or 401. The curved plate 1503 is positioned below the first or second clasps 301 or 401. During rotation, the cylindrical rod 1502 collides with the connecting rod, thereby driving the first or second clasps 301 or 401 to rotate. During upward movement, the curved plate 1503 is positioned below the connecting rod, hooking it and driving the spiral tube 2 upward.

[0089] The method for regulating and controlling building new energy cold and heat storage includes the following steps:

[0090] A. The surface platform 1 is fixed to the ground, with its top surface no lower than the ground level. The spiral tube 2 is buried in the soil through the through hole 101. There are two ways to bury the soil. The first is to dig out the soil below the through hole 101, then place the spiral tube 2 vertically into the through hole 101, and then backfill the soil. The other is to not dig out the soil, but to move the spiral tube 2 downward while rotating, similar to tightening a screw, and rotate the spiral tube 2 to the specified position. Since the spiral tube 2 occupies a limited space, there is no need to consider the problem of soil extraction. During the rotation of the spiral tube 2, it squeezes the soil in all directions, making the soil more compact.

[0091] B. When storing thermal energy: The heat source flows in through the liquid inlet main pipe 10, then flows into the interior of the spiral tube 2 through the liquid inlet branch pipes 6, the extension rod 4, and the vertical pipe 3, heating the phase change tube 203 inside. The phase change material inside the phase change tube 203 absorbs the heat and undergoes a phase change, storing the thermal energy. The heat source bypasses the first partition 202 and flows from the end of the spiral tube 2 into another cavity, then flows along the vertical pipe, the extension rod, and the liquid return branch pipe 7 into the interior of the liquid return main pipe 9, thus circulating.

[0092] C. When releasing heat energy: the cold source flows through the same path, enters the spiral tube 2 to absorb the heat inside the phase change tube 203, and increases the temperature of the cold source;

[0093] D. When using soil temperature for temperature adjustment: In summer, the underground soil temperature is lower than the outdoor and indoor temperatures. The phase change tube 203 contacts the spiral tube 2 through the first partition 202 to conduct heat, so that the temperature stored in the phase change tube 203 is the same as the soil temperature. The circulating fluid flows into the spiral tube 2 to cool the room, thereby cooling the room and adjusting the indoor temperature.

[0094] In winter, the underground soil temperature is higher than the outdoor and indoor temperatures. The circulating fluid flows into the spiral tube 2 to heat up, and then heats the room to adjust the indoor temperature.

[0095] E. Since the adjacent spiral tubes 2 are arranged in a staggered manner, the distance between each spiral tube 2 is long, which facilitates the utilization of the heat energy of the surrounding soil. By adjusting the opening and closing of the electric control valves 8 on each liquid inlet branch pipe 6 and liquid return branch pipe 7, each spiral tube 2 is utilized in an orderly manner to avoid imbalance in the underground soil temperature layer;

[0096] F. Regularly adjust the height of each spiral tube 2 to make full use of the soil heat energy. When the spiral tube 2 is moved upward, fix the shifter, and the connecting piece 15 is sleeved on the vertical tube 3. The arc plate 1503 passes through the first clamping ring 301. The hydraulic station is connected to the hydraulic cylinder 13 to control the piston rod 1301 to move upward. When the piston rod 1301 moves upward, the connecting piece 15 rotates, and the arc plate 1503 rotates to the bottom of the radial connecting rod between the first clamping ring 301 and the vertical tube 3, so that the connecting piece 15 moves upward and drives the vertical tube 3 to move upward, and rotates synchronously. The outer side of the spiral tube 2 is provided with a cutting surface 201, so that its upward movement during rotation can reduce the resistance of the soil to it, which facilitates the up and down movement of the spiral tube 2;

[0097] When the spiral tube 2 moves downward, remove the upper end cover 5 above the vertical tube 3, fix the bottom of the extension rod 4 to the vertical tube 3, then move the threaded tube 12 upward, and put the connecting piece 15 on the top of the extension rod 4. The piston rod 1301 pushes the spiral tube 2 to rotate and move downward through the connecting piece 15.

[0098] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.

The surface platform (1) is fixed on the ground, with its top surface not lower than the ground level, and the spiral tube (2) is buried in the soil through the through hole (101); B. When storing heat energy: the heat source flows in through the liquid inlet main pipe (10), then flows into the interior of the spiral tube (2) through each liquid inlet branch pipe (6), the extension rod (4), and the vertical pipe (3), heating the phase change tube (203) inside the spiral tube (2). The phase change material inside the phase change tube (203) absorbs the heat and produces a phase change, thereby storing the heat energy. The heat source bypasses the first partition (202) and flows from the end of the spiral tube (2) into another cavity, and then flows along the vertical pipe, the extension rod, and the liquid return branch pipe (7) into the interior of the liquid return main pipe (9), thereby circulating; C. When releasing heat energy: the cold source flows through the same path, enters the spiral tube (2) and absorbs the heat inside the phase change tube (203), thereby increasing the temperature of the cold source; D. When using soil temperature for temperature adjustment: In summer, the underground soil temperature is lower than the outdoor and indoor temperatures. The phase change tube (203) contacts the spiral tube (2) through the first partition (202) to conduct heat, so that the temperature stored in the phase change tube (203) is the same as the soil temperature. The circulating fluid flows into the spiral tube (2) to cool the room, and then cools the room to adjust the indoor temperature. In winter, the underground soil temperature is higher than the outdoor and indoor temperatures, and the circulating fluid flows into the spiral tube (2) to increase the temperature, and then heats the room to adjust the indoor temperature; E. Since the adjacent spiral tubes (2) are arranged in a staggered manner, the distance between each spiral tube (2) is long, which facilitates the utilization of the heat energy of the surrounding soil. By adjusting the opening and closing of the electric control valve (8) on each liquid inlet branch pipe (6) and liquid return branch pipe (7), each spiral tube (2) is utilized in an orderly manner to avoid the imbalance of the underground soil temperature layer; F.

When the piston rod (1301) moves upward, the connecting piece (15) rotates, and the arc plate (1503) rotates to the bottom of the radial connecting rod between the first clamping ring (301) and the vertical tube (3), so that the connecting piece (15) moves upward and drives the vertical tube (3) to move upward, and rotates synchronously. The outer side of the spiral tube (2) is provided with a cutting surface (201), so that the upward movement during its rotation can reduce the resistance of the soil to it, which facilitates the upward movement of the spiral tube (2); When the spiral tube (2) moves downward, the upper end cover (5) above the vertical tube (3) is removed, the bottom of the extension rod (4) is fixedly connected to the vertical tube (3), and then the threaded tube (12) is moved upward, and the connecting piece (15) is sleeved on the top of the extension rod (4). The piston rod (1301) pushes the spiral tube (2) to rotate and move downward through the connecting piece (15).
