Description

Technical Field

[0001] This invention relates to the field of energy-saving heat recovery technology, and in particular to a green building insulation and energy-saving device. Background Technology

[0002] Building insulation and energy-saving device is a waste heat recovery and energy-saving system applied to household air conditioners. It aims to solve the energy waste problem caused by the direct emission of a large amount of heat energy during the operation of traditional air conditioners. The device is mainly used to recover the waste heat (cold) energy generated during the cooling or heating operation of household air conditioners. Through heat exchange technology, the waste heat that was originally discharged to the outside is collected and reused for preheating domestic water or assisting in indoor insulation, so as to realize the cascade utilization of energy.

[0003] The device adds a heat exchange module to the outdoor unit of the air conditioner, which uses a high-efficiency heat transfer medium to capture the heat of the high-temperature and high-pressure gas discharged from the compressor. The heat energy is then transferred to the water storage device or the indoor floor heating system through the heat exchange system. In summer, the condensation heat is recovered to heat domestic water, and in winter, it helps to increase the indoor temperature. This realizes the secondary utilization of the energy consumption of the air conditioner, effectively reducing the overall energy consumption of the household and improving the building's energy efficiency rating.

[0004] Existing household air conditioner heat recovery devices generally adopt an independent design with one unit for each use. Each air conditioner outdoor unit needs to be equipped with a separate heat exchanger, and the equipment cannot work together. When users add air conditioners, they must purchase a complete set of heat exchange equipment, resulting in repeated investment in equipment, crowded installation space, and increased system maintenance costs. In addition, existing devices lack flexible operating modes. When a single air conditioner is running, the heat exchange capacity cannot be fully utilized. When multiple units are running at the same time, it is difficult to achieve overall heat energy allocation, resulting in low energy utilization efficiency and equipment idle waste.

[0005] Therefore, a green building thermal insulation and energy-saving device is proposed to solve the above problems. Summary of the Invention

The output end of the rotary motor passes through the top of the heat preservation tank and is fixedly connected to the top of the upper gear. The output end of the rotary motor is also sealed and rotatably connected to the top of the heat preservation tank.

[0009] In the above technical solution, furthermore, an arc-shaped expansion frame is fixedly connected to the inside of each of the two areas of the heat preservation tank, and the inside of the arc-shaped expansion frame is sealed and connected to the inside of the heat preservation tank.

[0010] In the above technical solution, the adjusting mechanism further includes an electric telescopic cylinder, and a pair of electric telescopic cylinders are provided. The top of the top rod is provided with a rectangular block at a position above the sealing plate. The top of the rectangular block is rotatably connected to a top gear. The top of the sealing plate is fixedly connected to a rotating shaft. The top of the rotating shaft passes through the rectangular block and is fixedly connected to the bottom of the top gear. The side wall of the rectangular block is fixedly connected to a guide rail. The side wall of the guide rail is laterally slidably connected to a rack. The rack and the top gear mesh with each other. The side wall of the rack is fixedly connected to a round rod. The electric telescopic cylinder is fixedly connected to the top of the heat preservation tank. The output end of the electric telescopic cylinder passes through the top of the heat preservation tank and is fixedly connected to a right-angled plate with an inclined surface.

[0011] In the above technical solution, a gap is left between the top of the top rod and the top of the inner end of the heat preservation tank, the right angle plate is set above the round rod, the output end of the electric telescopic cylinder is sealed and slidably connected to the top of the inner end of the heat preservation tank, a side block is fixedly connected to the side wall of the guide rail, and a return spring is fixedly connected between the side block and the side wall of the rack.

[0012] In the above technical solution, the sealing plate is further configured as a parallelogram with inclined sides, the through groove is configured as a parallelogram groove adapted to the sealing plate, and an upper sealing strip is fixedly connected to the opposite ends of one side of the two sealing plates, and a lower sealing strip is fixedly connected to the opposite ends of the other sides of the two sealing plates.

[0013] In the above technical solution, further, a telescopic frame is fixedly connected to the top of the top rod, and telescopic rods are slidably connected to both sides of the telescopic frame. The telescopic rods on opposite sides are fixedly connected to the side wall of the rectangular block. A drive motor is fixedly connected to the middle of the top of the insulation tank. The output end of the drive motor passes through the top of the insulation tank and is fixedly connected to the top of the telescopic frame.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This invention adopts a double-chamber cylindrical structure with an openable partition in the middle dividing the interior into two independent areas. Each area is equipped with a two-way upper and lower rotary joint to connect to the external air conditioning unit, realizing the function of a single heat exchanger shared by four air conditioners. When a single unit is running, a single area works independently and heats the water in a zone. When two units are running, the two areas operate independently at the same time without interfering with each other. When multiple units are running or the water demand increases, the partition can be opened to connect the two chambers, forming a large-capacity heat exchange space. This allows for flexible adaptation to different load scenarios, avoids duplicate equipment purchases, and significantly improves the system's economy and space utilization.

[0017] 2. When the two chambers are connected, the sealing plate actively rotates to form mechanical turbulence, breaking the water stratification and flow dead zone, promoting the full mixing and convection of high and low temperature water, effectively improving the heat exchange uniformity and heat exchange efficiency, and avoiding the problems of uneven heating and cooling and heat exchange efficiency decay in the traditional static connection mode.

Detailed Implementation

[0030] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0032] In practical use, it has been found that existing household air conditioner heat recovery devices generally adopt an independent design with one unit for each use. Each air conditioner outdoor unit needs to be equipped with a separate heat exchanger, and the devices cannot work together. When users add air conditioners, they must purchase a complete set of heat exchange devices, resulting in repeated investment in equipment, crowded installation space, and increased system maintenance costs. In addition, existing devices lack flexible operating modes. When a single air conditioner is running, the heat exchange capacity cannot be fully utilized. When multiple units are running at the same time, it is difficult to achieve overall heat energy allocation, resulting in low energy utilization efficiency and equipment idle waste. To solve the above problems, the following structure has been invented.

[0033] like Figures 1-11 The green building thermal insulation and energy-saving device shown includes a thermal insulation tank 1. A partition 2 is fixedly connected to the middle of the inner side of the thermal insulation tank 1, which divides the thermal insulation tank 1 into two areas. Water inlet pipes 3 are fixedly connected to the top of the inner side of both areas of the thermal insulation tank 1, and water outlet pipes 4 are fixedly connected to the bottom of the inner side of both areas of the thermal insulation tank 1. Through grooves 5 are opened on both sides of the outer wall of the partition 2. A sealing plate 6 is rotatably connected to the bottom of the through grooves 5. A top rod 7 is fixedly connected to the top of the partition 2. An adjustment mechanism for adjusting the position of the sealing plate 6 is provided on the top rod 7. An upper rotary joint 8 is fixedly connected to the top of both areas of the thermal insulation tank 1, and a lower rotary joint 9 is fixedly connected to the bottom of both areas of the thermal insulation tank 1. Both the upper rotary joint 8 and the lower rotary joint 9 are double-pipe rotary joints. A heat exchange tube 10 is installed between the two joints at the rotating end of the upper rotary joint 8 and the lower rotary joint 9 by bolt sealing. A rotating mechanism for driving the heat exchange tube 10 to rotate is also provided.

[0034] The rotating mechanism includes a rotary motor 11, which is provided with a pair of gear rings 12. The outer wall of the rotating end of the upper rotary joint 8 is fixedly connected to the gear ring 12. The top of the inner end of the heat preservation tank 1 is rotatably connected to an upper gear 13 that meshes with the gear ring 12. The rotary motor 11 is fixedly connected to the top of the heat preservation tank 1. The output end of the rotary motor 11 passes through the top of the heat preservation tank 1 and is fixedly connected to the top of the upper gear 13. The output end of the rotary motor 11 is sealed and rotatably connected to the top of the heat preservation tank 1.

[0035] An arc-shaped expansion frame 14 is fixedly connected to the inside of both areas of the heat exchange tank 1. The inside of the arc-shaped expansion frame 14 is sealed and connected to the inside of the heat exchange tank 1. By setting the arc-shaped expansion frame 14, the space of the heat exchange area inside the heat exchange tank 1 can be expanded, thereby ensuring that the heat exchange tube 10 can have an independent rotation area and avoiding affecting the rotation range of the subsequent sealing plate 6.

[0036] The adjustment mechanism includes an electric telescopic cylinder 15, which is provided in pairs. The top of the push rod 7 is provided with a rectangular block 16 at a position above the sealing plate 6. The top of the rectangular block 16 is rotatably connected to a top gear 17. The top of the sealing plate 6 is fixedly connected to a rotating shaft 18. The top of the rotating shaft 18 passes through the rectangular block 16 and is fixedly connected to the bottom of the top gear 17. The side wall of the rectangular block 16 is fixedly connected to a guide rail 19. The side wall of the guide rail 19 is laterally slidably connected to a rack 20. The rack 20 and the top gear 17 mesh with each other. The side wall of the rack 20 is fixedly connected to a round rod 21. The electric telescopic cylinder 15 is fixedly connected to the top of the heat preservation tank 1. The output end of the electric telescopic cylinder 15 passes through the top of the heat preservation tank 1 and is fixedly connected to a right-angle plate 36 with an inclined surface.

[0037] A gap is left between the top of the top rod 7 and the top of the inner end of the insulation tank 1. The right-angle plate 36 can be stored through the gap between the top rod 7 and the insulation tank 1 to avoid affecting the rotation of the sealing plate 6. The right-angle plate 36 is set above the round rod 21. The output end of the electric telescopic cylinder 15 is sealed and slidably connected to the top of the inner end of the insulation tank 1. The side block 22 is fixedly connected to the side wall of the guide rail 19. The return spring 23 is fixedly connected between the side block 22 and the side wall of the rack 20.

[0038] The sealing plate 6 is set as a parallelogram with inclined sides, and the through groove 5 is set as a parallelogram groove that matches the sealing plate 6. An upper sealing strip 24 is fixedly connected to the opposite end of one side of the two sealing plates 6, and a lower sealing strip 25 is fixedly connected to the opposite side of the other side of the two sealing plates 6. The sealing effect after the sealing plate 6 is stuck in the through groove 5 can be enhanced by setting the upper sealing strip 24 and the lower sealing strip 25.

[0039] During equipment installation, first install control valves on the inlet pipe 3 and outlet pipe 4, then connect them to the corresponding inlet and outlet pipes, and connect the condenser pipe of the outdoor unit of the air conditioner to the two flanges at the fixed end of the upper rotary joint 8. Then it can be put into operation. During the operation of the equipment, open the valve on the inlet pipe 3 to let the external cold water flow into the insulation tank 1 (it should be noted that the water level in the insulation tank 1 should not exceed three-quarters of the height of the partition 2 to ensure the isolation between the two areas). Then, during the operation of the air conditioner alone, the refrigerant of the outdoor unit of the air conditioner flows into the heat exchange pipe 10 through the upper rotary joint 8 to perform heat exchange treatment on the water in one area of ​​the insulation tank 1.

[0040] During this process, the controllable rotary motor 11 can start and drive the upper gear 13 to rotate, which in turn drives the meshing gear ring 12 to rotate, thereby driving the rotating end of the upper rotary joint 8 to rotate, while simultaneously driving the two heat exchange tubes 10 to rotate, and also driving the rotating end of the lower rotary joint 9 to rotate, thereby achieving the stirring and heat exchange effect on the hot water in one area and improving the heat exchange uniformity.

[0041] When multiple units are operating or water demand increases, the electric telescopic cylinder 15 can be activated to move the right-angle plate 36 upwards and reset it. This drives the right-angle plate 36 away from the round rod 21, gradually releasing the pressure on the rod 21. At this time, the rack 20 is pulled back by the spring force of the reset spring 23, thus resetting it. This, in turn, drives the meshing top gear 17 to rotate, which in turn drives the sealing plate 6 to rotate 90 degrees via the rotating shaft 18. (It should be noted that since both the sealing plate 6 and the through groove 5 are parallelograms,...) Furthermore, the two sealing plates 6 rotate in opposite directions. Therefore, when the sealing plate 6 rotates, it will drive the sealing plate 6 to rotate to the side of the upper sealing strip 24 and the lower sealing strip 25, so as to release the blockage of the through groove 5. Conversely, when the through groove 5 is blocked, the inclined surface of the sealing plate 6 will tightly press the inclined surface of the through groove 5, and drive the upper sealing strip 24 and the lower sealing strip 25 to press the outer wall of the partition plate 2, thereby achieving a tight seal on the through groove 5, thus releasing the blockage of the through groove 5, and allowing the water in the two areas to be connected.

[0042] In summary, the above-described structural design employs a dual-chamber cylindrical structure with an openable partition 2 dividing the interior into two independent zones. Each zone is equipped with a two-way upper rotary joint 8 and a lower rotary joint 9 for connection to the external air conditioning unit, enabling a single heat exchanger to function as a unit for four air conditioners. When a single unit is running, each zone operates independently, heating water in its designated area. When two units are running, both zones operate simultaneously and independently without interference. When multiple units are running or water demand increases, the partition 2 can be opened to connect the two chambers, creating a large-capacity heat exchange space. This design flexibly adapts to different load scenarios, avoids redundant equipment purchases, and significantly improves system economy and space utilization.

[0043] Based on the above embodiments, it was found during use that although the above structure can achieve independent and combined operation of two regions, the lack of a stirring structure between the two regions during combined operation will affect the uniform heat exchange effect of water. To solve the above problem, the above structure has been further improved.

[0044] A telescopic frame 26 is fixedly connected to the top of the top rod 7. Telescopic rods 27 are slidably connected to both sides of the telescopic frame 26. The telescopic rods 27 are fixedly connected to the side wall of the rectangular block 16 on the side away from each other. A drive motor 28 is fixedly connected to the middle of the top of the heat preservation tank 1. The output end of the drive motor 28 passes through the top of the heat preservation tank 1 and is fixedly connected to the top of the telescopic frame 26. A pair of straight grooves 29 are opened at the top of the top rod 7. The rotating shafts 18 are inserted into the inside of the straight grooves 29. Top grooves 30 are opened on both sides of the top of the telescopic frame 26. An upper rod 31 is fixedly connected to the top of the telescopic rod 27 relative to the position inside the top groove 30. A pair of upper plates 32 are fixedly connected to the inside of the heat preservation tank 1. An extrusion block 33 is fixedly connected to the bottom of the upper plate 32. The bottom of the extrusion block 33 is set higher than the top of the guide rail 19.

[0045] A pair of telescopic springs 34 are fixedly connected between the inner side of the telescopic frame 26 and the side wall of the telescopic rod 27. The extrusion block 33 is located next to the upper rod 31. The extrusion block 33 is set in a quarter circle shape. An arc-shaped inclined groove 35 is opened on the inner side of the extrusion block 33. The distance between the arc-shaped inclined groove 35 and the rotation center of the drive motor 28 gradually decreases.

[0046] When the two chambers are connected, the electric telescopic cylinder 15 is first controlled to fully reset the right-angle plate 36, driving the right-angle plate 36 to move above the upper plate 32. Then, the drive motor 28 is started to rotate the telescopic frame 26. At the same time, the top rod 7, the sealing plate 6, the telescopic rod 27, and the rectangular block 16 are rotated (at this time, the sealing plate 6 is in the open state on the through groove 5, so it is not restricted). At this time, the upper rod 31 will be rotated to the side of the extrusion block 33. Under the continuous rotation of the telescopic frame 26, the upper rod 31 will move to the inside of the arc-shaped inclined groove 35 and be squeezed by the inclined surface of the arc-shaped inclined groove 35. As the arc surface of the curved groove 35 gets closer and closer to the rotation center of the drive motor 28, it will gradually squeeze the upper rod 31 towards the center. At the same time, the upper rod 31 slides in the top groove 30 and pushes the telescopic rod 27 to slide inside the telescopic frame 26, compressing the telescopic spring 34. This also drives the rectangular block 16, the top gear 17, and the sealing plate 6 to move towards the center (to avoid the sealing plate 6 being obstructed by the rotation of the heat exchange tube 10, and since the top rod 7 is located above the heat exchange tube 10, only the position of the sealing plate 6 needs to be adjusted). At this time, the rotating shaft 18 will slide inside the straight groove 29.

[0047] Subsequently, the sealing plate 6 moves away from the rotation trajectory of the heat exchange tube 10, and the upper rod 31 moves out from the arc-shaped inclined groove 35, thereby relieving the pressure on the upper rod 31. Then, under the elastic force of the telescopic spring 34, the telescopic rod 27 and the rectangular block 16 are pushed to reset, and the sealing plate 6 is moved to reset. This process is repeated to drive the sealing plate 6 to rotate actively and form mechanical turbulence, which plays a stirring role for the water in the two areas.

[0048] In summary, through the design of the above structure, when the two chambers are connected, the sealing plate 6 actively rotates to form mechanical turbulence, breaking the water stratification and flow dead zone, promoting the full mixing and convection of high and low temperature water, effectively improving the heat exchange uniformity and heat exchange efficiency, and avoiding the problems of uneven heating and cooling and heat exchange efficiency decay in the traditional static connection mode.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of the present invention.

[0050] Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of the present invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
