Description

Technical Field

[0001] This utility model relates to the field of water supply and drainage hot water supply technology, and in particular to a hot water system that combines solar energy and air energy. Background Technology

[0002] Solar and air source heat pump combined water heating systems are a new type of environmentally friendly and energy-saving hot water supply technology. They effectively combine two renewable energy sources, solar and air source heat pumps, to improve the energy efficiency and stability of the system. The basic principle is to utilize a solar energy collection system and air source heat pump technology to achieve efficient heating and hot water supply under various climatic conditions. Solar water heating systems use solar collectors to convert solar radiation into heat energy to heat water. However, during long-term use, a large amount of dust and impurities accumulate on the surface of the collector tubes, reducing the absorption efficiency of sunlight and affecting the overall performance of the system. This cleaning problem is particularly pronounced in areas with high levels of dust.

[0003] A solar-air source water heating system disclosed in announcement number CN217330274U includes a solar water heating system, an insulated water tank, an air source water heating system, a centralized water pump device, a hot water supply pipeline, and a central controller. The output ends of the solar water heating system and the air source water heating system are connected to the input end of the insulated water tank. The input ends of the solar water heating system, the air source water heating system, and the hot water supply pipeline are all connected to the output end of the centralized water pump device. The input end of the centralized water pump device is connected to the output end of the insulated water tank. The output end of the hot water supply pipeline is connected to the input end of the water supply network. This utility model uses a centralized water pump device to simultaneously circulate the water in the insulated water tank among the solar water heating system, the air source water heating system, and the water supply network to raise the water temperature, and continuously circulate the hot water into the water supply network. This is accomplished by using a single centralized water pump device, saving installation costs.

[0004] However, this solar-air-source heat pump water heating system has the following disadvantages: During long-term use, the solar heating device cannot be regularly maintained and inspected, resulting in a large amount of dust and impurities covering the surface of the collector tubes, especially in areas with more sand and dust or more severe pollution. Consequently, the efficiency of solar energy conversion into heat energy will decrease, reducing the lifespan and stability of the system. Utility Model Content

[0005] (a) Technical problems to be solved The purpose of this invention is to provide a hot water system that combines solar energy and air energy, in order to solve the problem mentioned in the background art that, during long-term use, the solar heating device of the solar thermal system cannot be regularly maintained and inspected, resulting in a large amount of dust and impurities covering the surface of the heat collection tube, especially in areas with a lot of sand and dust or severe pollution. As a result, the efficiency of solar energy conversion into heat energy will be reduced, thus reducing the lifespan and stability of the system.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a solar and air energy combined hot water system, comprising a collector body, a plurality of collector tubes fixedly connected to one side of the collector body, a self-cleaning component slidably connected to the top of the collector tubes, a return pipe fixedly connected to the other end of the collector body, and a shock-absorbing component fixedly connected to the surface of the return pipe; the self-cleaning component includes a brush slidably connected to the top of the collector tubes, a sliding plate fixedly connected to the top of the brush, and a threaded rod threadedly connected to one end of the sliding plate; the shock-absorbing component includes a silicone ring fixedly connected to the surface of the return pipe, an upper retaining ring fixedly connected to the surface of the silicone ring, and a lower retaining ring rotatably connected to the bottom of the upper retaining ring.

[0007] As a further embodiment of this utility model, a rubber strip is fixedly connected to the top of the brush, and a sliding rod is slidably connected to the other end of the slide plate. Foot plates are fixedly connected to both ends of the sliding rod. The rubber strip helps the brush to make a softer contact with the surface of the heat collection tube, and plays a soft buffering role during the cleaning process, so as to avoid scratches or damage to the surface of the heat collection tube when the brush comes into direct contact with the heat collection tube.

[0008] As a further embodiment of this utility model, a gearbox is fixedly connected to the other end of the threaded rod, and a motor is fixedly connected to one side of the gearbox. The gearbox allows the motor to adjust its rotation speed, drive the threaded rod to rotate, and through the threaded connection, drive the movement of the slide plate by the rotation of the threaded rod, thereby driving the linear end of the brush, so that the brush can perform regular and continuous cleaning work on the surface of the heat collection tube.

[0009] As a further embodiment of this utility model, two sets of connecting shafts are rotatably connected to both ends of the upper retaining ring. A locking plate is rotatably connected to the surface of one set of connecting shafts, and a connecting block is rotatably connected to the surface of the other set of connecting shafts. By setting the connecting shafts, the two sets of connecting shafts provide rotatable mounting bases for the locking plate and the connecting block, respectively, to meet the angle adjustment requirements during subsequent locking or disassembly, and to extend the service life of the component.

[0010] As a further embodiment of this utility model, a fixed base is fixedly connected to the bottom of the lower retaining ring, and multiple sets of damping hydraulic rods are fixedly connected to the bottom of the fixed base. A mounting plate is fixedly connected to the bottom of the damping hydraulic rod. By setting the damping hydraulic rod, the damping hydraulic rod can further absorb and buffer the vibration and impact force generated by the return pipeline.

[0011] As a further embodiment of this utility model, a water inlet pipe is fixedly connected to the other end of the collector body, and an insulated water tank is fixedly connected to the other end of the water inlet pipe. A high-pressure water pump is fixedly connected to one side of the insulated water tank. By setting up the insulated water tank, the insulated water tank can reduce the frequent operation of the heating system, and at the same time, effectively reduce energy consumption and thus reduce operating costs.

[0012] As a further embodiment of this utility model, a buffer water tank is fixedly connected to the other end of the high-pressure water pump, and an air source heat pump is fixedly connected to the back of the buffer water tank. By setting up the air source heat pump, it can play a role in situations where the utilization effect of solar energy is poor, such as on cloudy days or in winter. By combining these two energy sources, a stable hot water supply can be achieved around the clock, while optimizing energy use, reducing the operating cost of the system, and providing an efficient hot water supply by utilizing the complementary advantages of the two.

[0013] As a further embodiment of this utility model, a cold water pipe is fixedly connected to the other side of the buffer water tank, a hot water pipe is fixedly connected to the front of the buffer water tank, and a pipe support is provided on one side of the collector body. The cold water pipe serves to deliver cold water to the buffer water tank, providing a continuous water supply to the system and ensuring the continuity of hot water supply.

[0014] (III) Beneficial Effects This utility model provides a hot water system that combines solar energy and air energy, which has the following beneficial effects: 1. This solar and air-source combined hot water system, through the inclusion of a self-cleaning component, activates the motor when regular cleaning of dust and dirt from the collector tube surface is required. The motor's rotation speed is adjusted via a gearbox, driving a threaded rod to rotate. This rotation, through a threaded connection, moves a sliding plate, which in turn moves the linear end of a brush. This allows the brush to perform regular and continuous cleaning of the collector tube surface. The brush effectively removes dust and dirt, while rubber strips help the brush make a gentler contact with the collector tube surface, providing a soft cushioning effect during cleaning and preventing scratches or damage to the collector tube surface from direct brush contact. This effectively removes dust, dirt, and other impurities adhering to the collector tube surface, achieving a regular automatic cleaning function. This reduces the frequency and cost of manual cleaning, ensures the overall system's high efficiency over a long period, and extends the system's lifespan and stability.

[0015] 2. This solar and air-source heat pump combined hot water system, through the installation of vibration damping components, prevents damage to the return pipe caused by vibration during operation. First, a silicone ring is fitted onto the surface of the return pipe, directly adhering to its surface. The excellent elasticity and flexibility of the silicone absorb the vibration energy generated by the high-speed water flow and equipment operation, achieving vibration reduction and noise reduction, and preventing long-term vibration from causing loosening or fatigue damage at pipe connections. Then, the upper and lower retaining rings are rotated and connected via a connecting block. Finally, the locking plate is manually pulled, locking onto the limiting block on one end of the lower retaining ring, causing the upper and lower retaining rings to merge and lock tightly, making the overall structure of the vibration damping component more stable. Simultaneously, the damping hydraulic rod further absorbs and buffers the vibration and impact force generated by the return pipe, effectively reducing the vibration and impact force generated by the return pipe, making the overall structure more rationally stressed, reducing pipe wear, and extending the service life of the pipe.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figures 1 to 4 This utility model provides a technical solution: a hot water system combining solar energy and air energy, including a collector body 1, a plurality of sets of collector tubes 2 fixedly connected to one side of the collector body 1, a self-cleaning component 3 slidably connected to the top of the collector tubes 2, a return pipe 4 fixedly connected to the other end of the collector body 1, and a shock-absorbing component 5 fixedly connected to the surface of the return pipe 4; the self-cleaning component 3 includes a brush 301 slidably connected to the top of the collector tubes 2, a sliding plate 302 fixedly connected to the top of the brush 301, and a threaded rod 303 threadedly connected to one end of the sliding plate 302; the shock-absorbing component 5 includes a silicone ring 501 fixedly connected to the surface of the return pipe 4, an upper retaining ring 502 fixedly connected to the surface of the silicone ring 501, and a lower retaining ring 503 rotatably connected to the bottom of the upper retaining ring 502.

[0020] A rubber strip 6 is fixedly connected to the top of the brush 301, and a sliding rod 7 is slidably connected to the other end of the slide plate 302. Foot plates 8 are fixedly connected to both ends of the sliding rod 7. The rubber strip 6 helps the brush 301 to make a softer contact with the surface of the heat collection tube 2, and plays a soft buffering role during the cleaning process, so as to avoid scratches or damage to the surface of the heat collection tube 2 when the brush 301 directly contacts the heat collection tube 2.

[0021] The other end of the threaded rod 303 is fixedly connected to a gearbox 9, and a motor 10 is fixedly connected to one side of the gearbox 9. The gearbox 9 allows the motor 10 to adjust its rotation speed and drive the threaded rod 303 to rotate. Through the threaded connection, the rotation of the threaded rod 303 drives the slide plate 302 to move, which in turn drives the linear end of the brush 301, enabling the brush 301 to perform regular and continuous cleaning work on the surface of the heat collection tube 2.

[0022] The upper retaining ring 502 has two sets of connecting shafts 11 rotatably connected to its two ends. One set of connecting shafts 11 has a locking plate 12 rotatably connected to its surface, and the other set of connecting shafts 11 has a connecting block 13 rotatably connected to its surface. The connecting shafts 11 provide a rotatable mounting base for the locking plate 12 and the connecting block 13 respectively, which meets the angle adjustment requirements during subsequent locking or disassembly and extends the service life of the components.

[0023] The bottom of the lower retaining ring 503 is fixedly connected to a fixed base 14, and the bottom of the fixed base 14 is fixedly connected to multiple sets of damping hydraulic rods 15. The bottom of the damping hydraulic rods 15 is fixedly connected to a mounting plate 16. Through the setting of the damping hydraulic rods 15, the damping hydraulic rods 15 can further absorb and buffer the vibration and impact force generated by the return pipe 4.

[0024] The other end of the collector body 1 is fixedly connected to a water inlet pipe 17, and the other end of the water inlet pipe 17 is fixedly connected to an insulated water tank 18. A high-pressure water pump 19 is fixedly connected to one side of the insulated water tank 18. The insulated water tank 18 can reduce the frequent operation of the heating system and effectively reduce energy consumption, thereby reducing operating costs.

[0025] The other end of the high-pressure water pump 19 is fixedly connected to a buffer water tank 20, and the back of the buffer water tank 20 is fixedly connected to an air source heat pump 21. The air source heat pump 21 is used to provide a stable hot water supply around the clock when the solar energy utilization effect is poor, such as on cloudy days or in winter. By combining these two energy sources, energy use can be optimized and the operating cost of the system can be reduced. The complementary advantages of the two can be used to provide an efficient hot water supply.

[0026] A cold water pipe 22 is fixedly connected to the other side of the buffer water tank 20, and a hot water pipe 23 is fixedly connected to the front of the buffer water tank 20. A pipe support 24 is provided on one side of the collector body 1. The cold water pipe 22 is used to deliver cold water to the buffer water tank 20, providing a continuous water supply to the system and ensuring the continuity of hot water supply.

[0027] In this invention, the working steps of the device are as follows: First step: When it is necessary to clean the dust and dirt on the surface of the heat collector tube 2 regularly, start the motor 10. The motor 10 adjusts the rotation speed through the gearbox 9, drives the threaded rod 303 to rotate, and through the threaded connection, the rotation of the threaded rod 303 drives the slide plate 302 to move, thereby driving the linear end of the brush 301, so that the brush 301 can perform regular and continuous cleaning work on the surface of the heat collector tube 2. The brush 301 is used to actually clean the dust and dirt on the surface of the heat collector tube 2. At the same time, the rubber strip 6 can help the brush 301 to make a softer contact with the surface of the heat collector tube 2, and play a soft buffering role during the cleaning process, so as to avoid scratches or damage to the surface of the heat collector tube 2 when the brush 301 directly contacts the heat collector tube 2. Second step: When it is necessary to prevent the return pipe 4 from being damaged by vibration during operation, first put the silicone ring 501 on the surface of the return pipe 4 and directly adhere it to the surface of the return pipe 4. With the excellent elasticity and flexibility of silicone, it absorbs the vibration energy generated by the high-speed flow of water in the pipe and the operation of the equipment, so as to achieve the effect of vibration reduction and noise reduction, and avoid long-term vibration leading to loosening or fatigue damage at the pipe connection. Third step: Next, connect the upper retaining ring 502 and the lower retaining ring 503 by rotating them through the connecting block 13. Finally, manually pull the locking plate 12 to lock the limiting block on one end of the lower retaining ring 503, so that the upper retaining ring 502 and the lower retaining ring 503 are locked together, making the overall structure of the shock absorption component 5 more stable. At the same time, the damping hydraulic rod 15 further absorbs and buffers the vibration and impact force generated by the return pipe 4.
