Description

[0001] The present invention relates to the technical field of heat storage water tanks, and specifically relates to a heat storage water tank with good heat preservation effect. Background Art

[0002] Solar energy is a simple, easily available and very clean energy source. Through different conversion technologies, solar energy can be converted into electrical energy, and it can also be directly used in the form of heat energy. A heat storage water tank is a simple way to utilize solar energy. By heating the water in the water tank through a collector, solar energy can be stored in the water in the form of heat for people to use.

[0003] However, in the existing heat storage water tank, there will be cavities in the tank according to different water levels, which will affect the heat preservation effect of the water tank to a certain extent. At the same time, in relatively cold weather, the water inside the collector for heat exchange will freeze and damage the collector. On the other hand, due to the working principle of the collector, there needs to be a certain height difference between the collector and the heat storage water tank, and the height of the heat storage water tank may need to be adjusted during the installation process at different positions, which is rather inconvenient.

Detailed implementation manners

[0034] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0035] As Figure 1 , Figure 3 , Figure 12 As shown in

[0036] Specifically, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 10 , Figure 11 , Figure 12As shown, the heat preservation structure 2 includes a first screw rod 204. The middle part of the water storage tank 1 is rotatably connected with the first screw rod 204. A piston plate 207 is threadedly connected to the first screw rod 204. A sealing ring 208 is fixedly connected to the side surface of the piston plate 207. The piston plate 207 is slidably connected to the inner side wall of the water storage tank 1 through the sealing ring 208. A cylindrical inner heat preservation layer 203 is arranged inside the water storage tank 1. A heat preservation plate 205 is fixedly connected to the bottom side of the piston plate 207. A motor 201 is installed on the top side of the water storage tank 1. The top end of the first screw rod 204 is fixedly connected to the motor 201 through a coupling. A one-way air inlet valve 202 is installed on the top of the water storage tank 1. A conversion pipe 206 is arranged in parallel with the side surface of the first screw rod 204. The conversion pipe 206 is slidably connected with the piston plate 207;

[0037] An inner heat preservation layer 203 is arranged in a circle in the inner layer of the water storage tank 1 for storing hot water. At the same time, a piston plate 207 that can be lifted and lowered is arranged inside the water storage tank 1. After electrically connecting the motor 201 on the top side of the water storage tank 1 to an external power supply, the piston plate 207 can be driven to move up and down in the water storage tank 1 through the driving action of the motor 201. After respectively connecting the two communication holes 8 at the bottom side of the water storage tank 1 to the water inlet pipe and the water outlet pipe, the extraction and release of the water in the water storage tank 1 can be realized through the lifting of the piston plate 207 in combination with the opening and closing of the water inlet pipe and the water outlet pipe. At the same time, since the water in the water storage tank 1 enters or exits through the extrusion of the piston plate 207, it can be ensured that the water surface can always be in contact with the heat preservation plate 205 at the bottom side of the piston plate 207, so that the heat preservation material can fully play the heat preservation effect.

[0038] Specifically, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 、 Figure 8 、 Figure 10 As shown, the heat storage structure 3 includes a first connecting pipe 301. The bottom end of the water storage tank 1 is fixedly connected with the first connecting pipe 301. The conversion pipe 206 is rotatably connected with the water storage tank 1. The bottom end of the conversion pipe 206 is communicated with the end of the first connecting pipe 301. The other end of the first connecting pipe 301 is connected with a collector 302. The bottom side of the collector 302 is connected with a second connecting pipe 303. The other end of the second connecting pipe 303 is communicated with the bottom of the water storage tank 1. A valve 304 is installed on one side of the second connecting pipe 303. The collector 302 is arranged at the bottom side of the water storage tank 1. A conversion hole 305 is opened at each end of the conversion pipe 206. The two conversion holes 305 are respectively arranged on both sides of the conversion pipe 206. Sealing gaskets 306 are respectively rotatably connected to both ends of the conversion pipe 206. The sealing gaskets 306 are in a "C" - shaped structure. The sealing gaskets 306 are fixedly connected with the water storage tank 1;

[0039] When the weather is cold, the conversion pipe 206 in the water storage tank 1 can be rotated so that the bottom conversion hole 305 of the conversion pipe 206 turns to the other side and is sealed by the corresponding gasket 306. At the same time, the conversion holes 305 at the top of the conversion pipe 206 also change their orientations simultaneously and are disengaged from the sealing state of the corresponding gaskets 306. Since both sides of the collector 302 are connected to the inside of the water storage tank 1 through the first connecting pipe 301 and the second connecting pipe 303 respectively, after closing the pipes connected to the two communication holes 8 at the bottom side of the water storage tank 1, as the conversion pipe 206 rotates, the first connecting pipe 301 will communicate with the cavity on the top side of the piston plate 207. At this time, if the piston plate 207 is driven to rise by the motor 201, then the air on the top side of the piston plate 207 will be pressed into the collector 302 through the conversion pipe 206 and the first connecting pipe 301, thereby discharging the water in the collector 302. After the collector 302 is emptied, the user needs to close the valve 304 on the second connecting pipe 303 to avoid damage to the collector 302 caused by freezing.

[0040] Specifically, as Figure 1 、 Figure 6 shown, the conversion structure 4 includes a control rod 401. The top end of the water storage tank 1 is rotatably connected to the control rod 401. The control rod 401 is fixedly connected to the top of the conversion pipe 206. A limiting block 402 is fixedly connected to the top side of the water storage tank 1. The limiting block 402 is of a semi-circular structure. The control rod 401 abuts against the side surface of the limiting block 402. A driving slide rod 403 is slidably connected to the inside of the control rod 401. A first spring 404 is fixedly connected between the driving slide rod 403 and the control rod 401. A plug rod 405 is vertically fixedly connected to the end of the driving slide rod 403. Two first clamping grooves 406 are formed on the water storage tank 1. The plug rod 405 is engaged with the water storage tank 1 through the first clamping grooves 406.

[0041] To facilitate the user to control the rotation of the conversion pipe 206, a control rod 401 is provided at the top end of the conversion pipe 206. The rotation range of the control rod 401 is limited by the limiting block 402. When the control rod 401 rotates from one side to the other side, one rotation adjustment of the conversion pipe 206 is completed. At the same time, to fix the rotation position of the conversion pipe 206, a driving slide rod 403 is provided inside the control rod 401. The plug rod 405 at the end of the driving slide rod 403 will be engaged with the first clamping groove 406 on the water storage tank 1 to fix the current position of the control rod 401. When the control rod 401 needs to be rotated, the user needs to simultaneously press the driving slide rod 403 at the end to disengage the plug rod 405 from the first clamping groove 406, and release the driving slide rod 403 when the control rod 401 turns to the other side to reposition it.

[0042] Specifically, as Figure 1 , Figure 3 , Figure 5 shown, the positioning structure 5 includes a positioning through hole 501. The positioning through hole 501 is provided on the side surface of the water storage tank 1. A guiding groove 506 is provided on the top side of the piston plate 207. The piston plate 207 is slidably connected with a clamping frame 502 through the guiding groove 506. An inclined surface block 504 is fixedly connected to the end of the clamping frame 502. The inclined surface block 504 is clamped with the side wall of the water storage tank 1 through the positioning through hole 501. A second spring 505 is fixedly connected between one end of the clamping frame 502 away from the inclined surface block 504 and the piston plate 207. The conversion pipe 206 penetrates through the clamping frame 502. A second clamping groove 503 is provided on the side surface of the conversion pipe 206. The inner side of the clamping frame 502 is an inclined surface structure. The clamping frame 502 is clamped with the conversion pipe 206 through the second clamping groove 503;

[0043] When the conversion pipe 206 is in different positions, in order to ensure the normal lifting of the piston plate 207, a one-way air inlet valve 202 is provided on the top side of the water storage tank 1. At the same time, a positioning through hole 501 is provided on the side of the water storage tank 1. When the bottom end of the conversion pipe 206 is communicated with the water storage tank 1, that is, at this time, both the first connecting pipe 301 and the second connecting pipe 303 are communicated with the bottom side of the water storage tank 1. At this time, the water in the water storage tank 1 will fill the heat collector 302, which is used to heat the water in the water storage tank 1. At the same time, through the positioning through hole 501, the cavity on the top side of the piston plate 207 can be balanced with the external air pressure, so as to ensure the normal lifting of the piston plate 207 and thus ensure the normal entry or discharge of hot water. When the top conversion hole 305 of the conversion pipe 206 is communicated with the inside of the water storage tank 1, at this time, the user can empty the heat collector 302 by lifting the piston plate 207. After the emptying step is completed, through the balancing effect of the one-way air inlet valve 202, the piston plate 207 can normally descend and reset. When the piston plate 207 moves below the positioning through hole 501, at this time, both the first connecting pipe 301 and the second connecting pipe 303 are in a closed state. At this time, it is equivalent to completing the emptying of the heat collector 302 and removing the heat collector 302. Opening the water inlet and outlet pipes connected by the two communication holes 8 can be used normally, providing protection for the heat collector 302 under cold conditions and avoiding heat dissipation through the heat collector 302; on the other hand, due to the existence of the positioning through hole 501, the air in the water storage tank 1 above the positioning through hole 501 is used to empty the heat collector 302. During normal use, the piston plate 207 should move below the positioning through hole 501 to avoid leakage of hot water. In order to position the movement of the piston plate 207, a clamping frame 502 is provided on the top side of the piston plate 207. When the heat collector 302 is in normal use, at this time, the movement of the piston plate 207 is relatively frequent. At this time, the second clamping groove 503 on the side of the conversion pipe 206 will face the first screw rod 204. When the piston plate 207 moves to the position of the positioning through hole 501, the clamping frame 502 will be clamped with the second clamping groove 503 under the push of the second spring 505. At the same time, the inclined surface block 504 at the end of the clamping frame 502 will also be clamped with the positioning through hole 501 to prevent the piston plate 207 from continuing to rise. Due to the inclined surface action of the clamping frame 502 and the inclined surface block 504, the piston plate 207 can normally descend, which is convenient for taking hot water.

[0044] Specifically, such as Figure 1 , Figure 2 , Figure 4 , Figure 9 , Figure 10 , Figure 11 , Figure 12As shown in the figure, the support structure 6 includes support columns 601. A plurality of support columns 601 are slidably connected to the side surface of the water storage tank 1. A threaded tooth ring 604 is threadedly connected to the support column 601. The threaded tooth ring 604 is rotatably connected to the water storage tank 1. A synchronous tooth ring 603 is rotatably connected to the bottom side of the water storage tank 1. The synchronous tooth ring 603 meshes with the threaded tooth ring 604. A transmission gear 605 is rotatably connected to the side surface of the water storage tank 1. The transmission gear 605 meshes with the synchronous tooth ring 603. A first bevel gear 606 is fixedly connected to the transmission gear 605. A second bevel gear 607 meshes with the side surface of the first bevel gear 606. A regulating rod 602 is fixedly connected to the middle of the second bevel gear 607. The regulating rod 602 is rotatably connected to the water storage tank 1;

[0045] For the convenience of installing the water storage tank 1 and the normal operation of the collector 302, the user can adjust the height of the water storage tank 1 by rotating the regulating rod 602 located on the side surface of the water storage tank 1. The rotation of the regulating rod 602 drives the transmission gear 605 to rotate through the transmission effect of the first bevel gear 606 and the second bevel gear 607. The rotation of the transmission gear 605 can further drive the synchronous tooth ring 603 to rotate. The threaded tooth rings 604 threadedly connected to the support columns 601 are respectively engaged with the side surface of the synchronous tooth ring 603. As the threaded tooth ring 604 rotates, the support position of the support column 601 for the water storage tank 1 can be adjusted, and thus the installation height of the water storage tank 1 can be adjusted.

[0046] Specifically, as Figure 7 、 Figure 10 、 Figure 12 shown in the figure, the observation structure 7 includes an indicating groove 703. An indicating groove 703 is formed on the side surface of the water storage tank 1. A second screw rod 702 is arranged in the indicating groove 703. The bottom end of the second screw rod 702 is rotatably connected to the water storage tank 1. A sealing block 701 is threadedly connected to the top end of the second screw rod 702. The bottom end of the sealing block 701 is of a square structure. The top end of the sealing block 701 abuts against the water storage tank 1. A transparent plate 704 is fixedly connected to the side surface of the water storage tank 1. A threaded block 705 is slidably connected to the water storage tank 1. The threaded block 705 is threadedly connected to the second screw rod 702. A sealing head 706 is slidably connected to the end of the threaded block 705. A third spring 707 is fixedly connected between the sealing head 706 and the threaded block 705. A communicating pipe 708 is fixedly connected to the side wall of the water storage tank 1. The end of the sealing head 706 is of an arc surface structure. The end of the sealing head 706 abuts against the end of the communicating pipe 708;

[0047] Since the inner insulation layer 203 is added in the water storage tank 1, it is inconvenient to directly check the liquid level position in the water storage tank 1. When the user wants to know the water level position in the water storage tank 1, the user can rotate the second screw rod 702 located at the bottom side of the water storage tank 1. At this time, the sealing blocks 701 and the threaded blocks 705 at both ends of the second screw rod 702 will move upward simultaneously. After the threaded block 705 is displaced, the sealing head 706 inside it will release the sealing effect on the communication pipe 708. At the same time, the sealing block 701 on the top side of the second screw rod 702 will also release the sealing effect on the top side of the indicating groove 703. At this time, the water inside the water storage tank 1 will flow into the indicating groove 703 and be flush with the liquid level in the water storage tank 1. At this time, the user can directly check through the transparent plate 704 on the side, and then turn the second screw rod 702 back to re-seal the communication pipe 708 to ensure the overall heat preservation effect of the water storage tank 1.

[0048] When the present invention is in use, first, an inner heat-insulating layer 203 is provided in the inner layer of the water storage tank 1 for storing hot water. At the same time, a piston plate 207 that can be lifted and lowered is provided inside the water storage tank 1. After electrically connecting the motor 201 on the top side of the water storage tank 1 to an external power source, the piston plate 207 can be driven to move up and down in the water storage tank 1 by the driving action of the motor 201. After connecting the two communication holes 8 at the bottom side of the water storage tank 1 to the water inlet pipe and the water outlet pipe respectively, the extraction and release of the water in the water storage tank 1 can be realized by the lifting of the piston plate 207 in combination with the opening and closing of the water inlet pipe and the water outlet pipe. At the same time, since the water in the water storage tank 1 enters or exits by the extrusion of the piston plate 207, it can be ensured that the water surface can always be in contact with the heat-insulating plate 205 at the bottom side of the piston plate 207, so that the heat-insulating material can fully exert its heat-insulating effect. When the weather is cold, the conversion pipe 206 in the water storage tank 1 can be rotated, so that the bottom conversion hole 305 of the conversion pipe 206 turns to the other side and is sealed by the corresponding gasket 306. At the same time, the conversion hole 305 at the top end of the conversion pipe 206 also changes its orientation and is separated from the sealing state of the corresponding gasket 306. Since both sides of the heat collector 302 are connected to the inside of the water storage tank 1 through the first connecting pipe 301 and the second connecting pipe 303 respectively, after closing the pipes connected to the two communication holes 8 at the bottom side of the water storage tank 1, as the conversion pipe 206 rotates, the first connecting pipe 301 will be connected to the cavity on the top side of the piston plate 207. At this time, if the piston plate 207 is driven to rise by the motor 201, the air on the top side of the piston plate 207 will be pressed into the heat collector 302 through the conversion pipe 206 and the first connecting pipe 301, thereby discharging the water in the heat collector 302. After the heat collector 302 is emptied, the user needs to close the valve 304 on the second connecting pipe 303 to avoid damage to the heat collector 302 due to freezing. In order to facilitate the user to control the rotation of the conversion pipe 206, a control rod 401 is provided at the top end of the conversion pipe 206, and the rotation range of the control rod 401 is limited by a limit block 402. When the control rod 401 rotates from one side to the other side, a rotation adjustment of the conversion pipe 206 is completed. At the same time, in order to fix the rotation position of the conversion pipe 206, a driving slide rod 403 is provided inside the control rod 401, and the insertion rod 405 at the end of the driving slide rod 403 will be engaged with the first card slot 406 on the water storage tank 1 to fix the position of the current control rod 401. When the control rod 401 needs to be rotated, the user needs to press the driving slide rod 403 at the end at the same time, so that the insertion rod 405 is disengaged from the first card slot 406, and the driving slide rod 403 can be released when the control rod 401 turns to the other side to reposition. When the conversion pipe 206 is in different positions, in order to ensure the normal lifting of the piston plate 207, a one-way air inlet valve 202 is provided on the top side of the water storage tank 1, and a positioning through hole 501 is opened on the side of the water storage tank 1. When the bottom end of the conversion pipe 206 is connected to the water storage tank 1,That is, at this time, both the first connecting pipe 301 and the second connecting pipe 303 are communicated with the bottom side of the water storage tank 1. At this time, the water in the water storage tank 1 will fill the heat collector 302 to exchange heat for the water in the water storage tank 1. At the same time, through the positioning through hole 501, the cavity on the top side of the piston plate 207 can be balanced with the external air pressure, so as to ensure the normal lifting and lowering of the piston plate 207 and thus ensure the normal entry or discharge of hot water. When the top conversion hole 305 of the conversion pipe 206 is communicated with the inner side of the water storage tank 1, at this time, the user can empty the heat collector 302 by lifting the piston plate 207. After the emptying step is completed, through the balancing effect of the one-way intake valve 202, the piston plate 207 can normally descend and reset. When the piston plate 207 moves below the positioning through hole 501, at this time, both the first connecting pipe 301 and the second connecting pipe 303 are in a closed state. At this time, it is equivalent to completing the emptying of the heat collector 302 and removing the heat collector 302. Opening the water inlet and outlet pipes connected by the two communication holes 8 can be used normally, providing protection for the heat collector 302 under cold conditions and avoiding heat dissipation through the heat collector 302; on the other hand, due to the existence of the positioning through hole 501, the air in the water storage tank 1 above the positioning through hole 501 is used to empty the heat collector 302. During normal use, the piston plate 207 should keep moving below the positioning through hole 501 to avoid leakage of hot water. In order to position the movement of the piston plate 207, a clamping frame 502 is provided on the top side of the piston plate 207. When the heat collector 302 is in normal use, at this time, the movement of the piston plate 207 is relatively frequent. At this time, the second clamping groove 503 on the side of the conversion pipe 206 will face the first screw rod 204. When the piston plate 207 moves to the position of the positioning through hole 501, the clamping frame 502 will be clamped with the second clamping groove 503 under the push of the second spring 505. At the same time, the inclined plane block 504 at the end of the clamping frame 502 will also be clamped with the positioning through hole 501 to prevent the piston plate 207 from rising further. Due to the inclined plane effect of the clamping frame 502 and the inclined plane block 504, the piston plate 207 can normally descend, which is convenient for taking hot water. In order to facilitate the installation of the water storage tank 1 and the normal operation of the heat collector 302, the user can adjust the height of the water storage tank 1 by rotating the adjusting rod 602 located on the side of the water storage tank 1. The rotation of the adjusting rod 602 drives the transmission gear 605 to rotate through the transmission effect of the first bevel gear 606 and the second bevel gear 607. The rotation of the transmission gear 605 can further drive the synchronous gear ring 603 to rotate. The threaded gear rings 604 threadedly connected to the support columns 601 are respectively engaged on the side of the synchronous gear ring 603. As the threaded gear ring 604 rotates, the support position of the support column 601 for the water storage tank 1 can be adjusted, and thus the installation height of the water storage tank 1 can be adjusted. Since the inner heat insulation layer 203 is added in the water storage tank 1, it is not convenient to directly check the liquid level position in the water storage tank 1. When the user wants to know the water level position in the water storage tank 1, the user can rotate the second screw rod 702 located at the bottom side of the water storage tank 1.At this time, the sealing blocks 701 and the threaded blocks 705 at both ends of the second screw rod 702 will move towards the top side simultaneously. After the threaded block 705 is displaced, the sealing head 706 inside it will release the sealing effect on the communication pipe 708. At the same time, the sealing block 701 on the top side of the second screw rod 702 will also release the sealing effect on the top side of the indicating groove 703. At this time, the water inside the water storage tank 1 will flow into the indicating groove 703 and be flush with the liquid level inside the water storage tank 1. At this time, the user can directly view it through the transparent plate 704 on the side, and then turn the second screw rod 702 back to re-seal the communication pipe 708 to ensure the overall heat preservation effect of the water storage tank 1.,
