[0050] External thread 207; the outer surface side wall of the disc 205 is provided with an external thread 207; the disc 205 and the outer shell 202 are connected by a threaded transmission between the internal thread 206 and the external thread 207;

[0051] Water tank 208; A water tank 208 is fixedly connected to the outer surface of the upper end of the disc 205; the water tank 208 is placed vertically;

[0053] Limiting rod 210; a limiting rod 210 is slidably connected in the limiting groove 209; the limiting rod 210 is "L"-shaped; the upper end of the limiting rod 210 is fixedly connected to the upper outer surface of the water tank 208.

[0054] The present invention is provided with a telescopic component 2 in the trapezoidal outer cover 1 to complete the lifting operation of the solar thermal storage device. First, a cylindrical empty groove 201 is opened at the upper end of the outer cover 1, and the interior of the empty groove 201 is connected to the outside world. At the same time, a rectangular groove 211 is opened in the wall thickness of the lower end of the empty groove 201, and an outer shell 202 is provided in the empty groove 201. The outer surface of the outer shell 202 is slidably connected to the empty groove 201, and a motor 203 is fixedly connected to the lower end of the inner surface of the rectangular groove 211. A transmission rod 204 is fixedly connected to the upper end of the motor 203, and the transmission rod 204 passes through the wall thickness between the empty groove 201 and the rectangular groove 211 and rotates between the outer surface of the wall thickness and the wall thickness. The transmission rod 204 passes through One end of the wall is fixedly connected to the outer surface of the lower end of the outer shell 202. When the motor 203 starts to rotate clockwise to start working, the outer shell 202 can be driven to rotate in the empty slot 201 through the transmission rod 204. Because the outer surface of the outer shell 202 is slidingly connected to the inner surface of the empty slot 201, the process of the motor 203 driving the outer shell 202 to rotate can be carried out smoothly. The present invention also provides a cylindrical disc 205 in the outer shell 202. The outer surface side wall of the disc 205 is provided with an external thread 207, and the inner surface of the outer shell 202 is provided with an internal thread 206. At this time, the disc 205 and the outer shell 202 can be threadedly connected through the internal thread 206 and the external thread 207. At the same time, the disc 20 5 is fixedly connected to a water tank 208 on the upper end of the outer surface. Placing the water tank 208 vertically reduces the footprint of the water tank 208. When the motor 203 drives the outer shell 202 to rotate clockwise, the disc 205 can cooperate with the internal thread 206 and the external thread 207 between the outer shell 202 to move the disc 205 and the water tank 208 on its upper end upward. In order to ensure that the disc 205 can smoothly drive the water tank 208 to work, an "L"-shaped limiting rod 210 is fixedly connected to the upper end of the outer surface of the water tank 208, and the outer surface of the limiting rod 210 is slidably connected to the "L"-shaped limiting groove 209 provided at the upper end of the outer shell 202, so that the limiting rod 210 can be used to adjust the water tank 208 to a certain extent. The water tank 208 is limited, and the sliding connection between the limit rod 210 and the limit groove 209 ensures that the motor 203 will not get stuck during the process of controlling the water tank 208 and other components to rise, thereby improving the working efficiency of the present invention. At the same time, the limit rod 210 can also play a stabilizing role, reducing the vibration generated by the equipment during operation. When the disc 205 drives the water tank 208 at its upper end to completely move out of the outer shell 202, the motor 203 stops working. When encountering some extreme weather, the motor 203 starts to rotate counterclockwise, and then the transmission rod 204 drives the outer shell 202 to rotate counterclockwise. At this time, under the action of the internal thread 206 and the external thread 207,The disc 205 drives the water storage tank 208 at its upper end to start moving downward. When the disc 205 moves to the lower left end of the outer shell 202, the motor 203 stops working, thereby completing the recovery of the solar thermal storage device, thereby protecting the solar thermal storage device, thereby increasing the service life of the solar thermal storage device and effectively reducing the cost of its maintenance.

[0055] A water inlet and a water outlet can be connected to the top of the water tank 208. When needed, water pipes can be spliced ​​at the upper ends of the water inlet and the water outlet. When it needs to be recycled, just unplug the water pipes at the upper ends of the water inlet and the water outlet, and it will not hinder the recycling work of the water tank 208.

[0056] As a specific embodiment of the present invention, the outer surface of the water tank 208 is provided with a solar heat collecting tube 3; the solar heat collecting tube 3 is a spiral structure; at least one connecting tube 4 is fixedly connected between the outer surface side wall of the solar water tank 208 and the solar heat collecting tube 3; one end of the connecting tube 4 is connected to the interior of the solar heat collecting tube 3; the other end of the connecting tube 4 is connected to the interior of the water tank 208.

[0057] A spiral solar heat collecting tube 3 is provided on the outer surface of the vertically placed water tank 208. The spiral structure of the solar heat collecting tube 3 can increase the area of ​​the solar heat collecting tube 3 exposed to sunlight, so that the water inside the solar heat collecting tube 3 can be heated up faster, thereby improving the working efficiency of the solar heat collecting tube 3. At the same time, at least one connecting tube 4 is fixedly connected between the solar heat collecting tube 3 and the outer surface side wall of the water tank 208, and the two ends of the connecting tube 4 are respectively connected to the solar heat collecting tube 3 and the interior of the water tank 208. When the water in the solar heat collecting tube 3 heats up, due to the lower density of the hot water, the hot water at the lower position floats to the upper end of the water tank 208, thereby driving the cold water inside the water tank 208 from the connecting tube 4 into the solar heat collecting tube 3 at the lower position to start heating, thereby accelerating the alternation between hot and cold water.

[0058] As a specific embodiment of the present invention, two hydraulic rods 5 are evenly fixedly connected to the lower end of the inner surface of the outer shell 202 along the circumferential direction; and the other ends of the two hydraulic rods 5 are fixedly connected to a supporting plate 6.

[0059] In the present invention, in order to ensure that the disc 205 and the water storage tank 208 at its upper end and the solar heat collecting tube 3 will not slowly move down along the internal thread 206 due to their own weight, two hydraulic rods 5 are evenly arranged along the circumferential direction at the lower end of the inner surface of the outer shell 202. When the disc 205 rises to the upper end of the outer shell 202, the two hydraulic rods begin to extend upward until the upper surface of the support plate 6 fixedly connected to its upper end is in contact with the outer surface of the lower end of the disc 205, thereby supporting the disc 205 and the water storage tank 208 at its upper end and the solar heat collecting tube 3. The support plate 6 is provided at the upper end of the hydraulic rod 5 to increase the contact area between the disc 205 and the outer surface of the lower end of the water storage tank 208, so that it can work more stably, thereby preventing the disc 205 from slowly moving down along the thread due to its own weight and the weight of the water storage tank 208 and the solar heat collecting tube 3, thereby improving the working efficiency of the solar heat collecting tube 3.

[0060] As a specific embodiment of the present invention, two card slots 7 are fixedly connected to the outer surface of the upper end of the outer cover body 1; the two card slots are both "L"-shaped; the two card slots 7 are arranged parallel to the outer surface of the upper end of the outer cover body 1; a top cover 8 is provided between the two card slots 7; the two sides of the top cover 8 are respectively slidably connected to the inner sides of the two card slots 7.

[0061] In order to further protect the water storage tank 208 and the solar heat collecting single tube from being affected by extreme weather, the present invention has a slot 7 arranged parallel to the two ends of the empty slot 201 on the outer surface of the upper end of the outer cover body 1, and the two slots 7 are fixedly connected to the outer surface of the upper end of the outer cover body 1, and a top cover 8 is slidably connected between the two slots 7. After the water storage tank 208 and the solar heat collecting tube 3 are recovered, it is only necessary to pull the top cover 8 in the straight direction of the two slots 7 to close the empty slot 201, so as to achieve further protection of the solar heat storage device when encountering some extreme weather. At the same time, this method can also reduce the possibility of freezing and cracking of the solar heat collecting tube 3 in winter, so that the service life of the solar heat collecting tube 3 can be further extended. When the water storage tank 208 and the solar heat collecting tube 3 need to be removed, it is only necessary to pull open the top cover 8 without affecting the normal operation of other components.

[0062] As a specific embodiment of the present invention, a rubber ring 9 is fixedly connected to the outer surface of the lower end of the top cover 8 ; and a handle 11 is fixedly connected to the front end of the outer edge of the top cover 8 .

[0063] In order to ensure that fine particles such as wind and sand cannot enter the interior of the outer cover body 1 through the gap between the top cover 8 and the empty slot 201 in extreme weather, a rubber ring 9 is fixedly connected to the outer surface of the lower end of the top cover 8. When the top cover 8 is closed, the rubber ring 9 can just close the opening at the upper end of the empty slot 201. In this way, when the top cover 8 is pulled to the upper end of the empty slot 201, the rubber ring 9 has a sealing property, so that the rubber ring 9 can further seal the opening at the upper end of the empty slot 201, thereby further reducing the possibility of damage to the solar energy collecting tube 3 inside it, thereby improving its working efficiency and extending its service life. A handle 11 is fixedly connected to the front end of the outer surface of the top cover 8, which makes it convenient for the operator to move the top cover 8 more easily.

[0064] As a specific embodiment of the present invention, a ladder 10 is fixedly connected to a side wall at one end of the outer surface of the outer cover 1 .

[0065] In order to ensure that the operator can smoothly climb to the upper end of the outer cover body 1, a ladder 10 is fixedly connected to the side wall of one end of the outer surface of the outer cover body 1. This method allows the operator to use the ladder 10 as a force when climbing the outer cover body 1, and also provides the climbing staff with a foothold to ensure their own stability. This method reduces the difficulty of the operator in the climbing process and also reduces the possibility of the operator falling and causing injury.

[0066] As a specific embodiment of the present invention, the diameter of the disk 205 is more than one centimeter larger than the diameter of the spiral solar heat collecting tube 3.

[0067] The present invention sets the diameter of the disc 205 to be more than one centimeter larger than the diameter of the spiral solar heat collecting tube 3. In this way, when the disc 205 drives the water tank 208 and the solar heat collecting tube 3 to move up and down, it will not be unable to move out normally due to the excessive diameter, thereby causing the solar heat collecting tube 3 to be unable to be used normally. At the same time, it also prevents the outer surface of the solar heat collecting tube 3 from being damaged by friction with the inner surface of the outer shell 202. This method improves the working efficiency of the present invention.

[0068] As a specific embodiment of the present invention, the top cover 8 and the outer cover body 1 are both made of polytetrafluoroethylene material.

[0069] The top cover 8 and the outer cover 1 are made of polytetrafluoroethylene material. Since polytetrafluoroethylene material has the characteristics of resistance to atmospheric aging and low permeability, when the water tank 208 and the solar heat collecting tube 3 are put into the outer cover 1, the top cover 8 is immediately closed, thereby reducing the speed at which the outside air enters the interior, thereby increasing the service life of the water tank 208 and the solar heat collecting tube 3. The polytetrafluoroethylene material is also non-toxic and high temperature resistant (up to 250 degrees), so that the outer cover 1 and the top cover 8 will not be greatly affected in summer or some relatively hot extreme weather.

[0070] A solar energy utilization device is composed of the above-mentioned solar heat storage components and indoor cold and hot water pipelines connected thereto.

[0071] Working principle: The trapezoidal outer cover 1 is used to protect or support the other components of the present invention. The telescopic component 2 in the outer cover 1 can support the solar thermal storage device after it is transported upward. The present invention is provided with a telescopic component 2 in the trapezoidal outer cover 1 to complete the lifting operation of the solar thermal storage device. First, a cylindrical hollow groove 201 is opened at the upper end of the outer cover 1, and the interior of the hollow groove 201 is connected to the outside world. At the same time, a rectangular groove 211 is opened in the wall thickness of the lower end of the hollow groove 201, and an outer shell 202 is provided in the hollow groove 201. The outer surface of the outer shell 202 is slidably connected to the hollow groove 201, and a motor 203 is fixedly connected to the lower end of the inner surface of the rectangular groove 211. The motor A transmission rod 204 is fixedly connected to the upper end of 203, and the transmission rod 204 passes through the wall thickness between the empty slot 201 and the rectangular slot 211 and is rotatably connected to the outer surface of the wall thickness through the outer surface of the wall thickness. One end of the transmission rod 204 passing through the wall thickness is fixedly connected to the outer surface of the lower end of the outer shell 202. When the motor 203 starts to rotate clockwise to start working, the outer shell 202 can be driven to rotate in the empty slot 201 by the transmission rod 204. Because the outer surface of the outer shell 202 is slidably connected to the inner surface of the empty slot 201, the process of the motor 203 driving the outer shell 202 to rotate can be carried out smoothly. The present invention also provides a cylindrical disc 205 in the outer shell 202, and the outer surface side wall of the disc 205 is provided with an external thread 2 07, the inner surface of the outer shell 202 is provided with an internal thread 206, at this time, the disc 205 and the outer shell 202 can be threadedly connected through the internal thread 206 and the external thread 207, and at the same time, a water tank 208 is fixedly connected to the upper end of the outer surface of the disc 205. Placing the water tank 208 vertically reduces the footprint of the water tank 208. When the motor 203 drives the outer shell 202 to rotate clockwise, the disc 205 can cooperate with the internal thread 206 and the external thread 207 between the outer shell 202 to move the disc 205 and the water tank 208 at its upper end upward. In order to ensure that the disc 205 can smoothly drive the water tank 208 to work, the upper end of the outer surface of the water tank 208 is fixedly connected to the upper end of the outer surface of the water tank 208. An "L"-shaped limiting rod 210 is fixedly connected, and the outer surface of the limiting rod 210 is slidably connected to the "L"-shaped limiting groove 209 opened at the upper end of the outer shell 202, so that the water tank 208 is limited by the limiting rod 210. At the same time, the sliding connection between the limiting rod 210 and the limiting groove 209 prevents the motor 203 from getting stuck and being unable to continue working during the process of controlling the water tank 208 and other components to rise, thereby improving the working efficiency of the present invention. At the same time, the limiting rod 210 can also play a stabilizing role, reducing the vibration generated by the equipment during operation. When the disc 205 drives the water tank 208 at its upper end to completely move out of the outer shell 202, the motor 203 stops working.When encountering some extreme weather, the motor 203 starts to rotate counterclockwise, and then the transmission rod 204 drives the outer shell 202 to rotate counterclockwise. At this time, under the action of the internal thread 206 and the external thread 207, the disc 205 drives the water storage tank 208 at its upper end to start moving downward. When the disc 205 moves to the lower end inside the outer shell 202, the motor 203 stops working, thereby completing the recovery of the solar thermal storage device, thereby protecting the solar thermal storage device, thereby increasing the service life of the solar thermal storage device and effectively reducing its maintenance cost. A water inlet and a water outlet can be connected to the top of the water tank. When needed, water pipes can be spliced ​​at the upper ends of the water inlet and the water outlet. When it needs to be recycled, just unplug the water pipes at the upper ends of the water inlet and the water outlet, and then it will not hinder the recovery of the water tank.
