Abstract

This invention discloses an energy-saving ground source heat pump, relating to the field of ground source heat pump technology. It includes a base and a water inlet plate, with a heat pump unit mounted on top of the base. In this energy-saving ground source heat pump, rainwater flows into a storage tank through the water inlet plate. Large particles are filtered out by a filter screen, and the rainwater is collected in the storage tank. Simultaneously, a motor drives a primary stirring rod to rotate, while a stirring mechanism uniformly agitates the water, resulting in a uniform temperature distribution and improved heat exchange efficiency. The primary stirring rod also drives a cleaning pusher plate to rotate, pushing large particles from the filter screen surface to the collection port. These large particles are then discharged to the outside of the storage tank through a guide plate and an outlet.

Description

Technical Field

[0001] This invention relates to the field of ground source heat pump technology, specifically to an energy-saving ground source heat pump. Background Technology

[0002] Ground source heat pumps use ground energy as the cooling source for summer cooling and the low-temperature heat source for winter heating. They are systems that provide heating, cooling, and domestic hot water, replacing traditional methods that use chillers and boilers for air conditioning, heating, and hot water supply. This is an effective way to improve the urban atmospheric environment and save energy. A ground source heat pump system includes an outdoor ground source heat exchange system, a water source heat pump unit, and indoor heating and air conditioning terminal systems. The working principle of a ground source heat pump is relatively simple. In summer, the evaporator of the heat pump unit absorbs heat from the building and sends it to the condenser. Simultaneously, the condenser releases the heat into the ground through heat exchange with groundwater. In winter, the evaporator of the heat pump unit absorbs heat from the groundwater as a heat source, and through the heat pump circulation, the condenser provides hot water for heating the building's interior.

[0003] In existing ground source heat pump technology, heat exchange occurs with groundwater or surface water. Ground source heat pumps can use rainwater for energy saving. Typically, rainwater is collected through multiple water storage components. After entering the water storage components, the rainwater contains a large number of impurities. These impurities accumulate in the water storage components over a long period of time and adhere to the inner wall of the water storage components, forming a thick sediment layer. This sediment layer affects the flow efficiency of rainwater in the water storage components and hinders rainwater from entering the heat exchange structure of the ground source heat pump. This results in high maintenance requirements for the ground source heat pump. Furthermore, after the rainwater has been stagnant for a long time, the water temperature is prone to uneven distribution, which affects the cooling and heating cycle efficiency of the ground source heat pump.

[0004] Therefore, we propose an energy-saving ground source heat pump. Summary of the Invention

[0005] The purpose of this invention is to provide an energy-saving ground source heat pump to solve the problems mentioned in the background art. In the process of collecting rainwater, the rainwater contains a large number of impurities. After long-term accumulation in the water storage component, these impurities will adhere to the inner wall of the water storage component and form a thick sediment layer. These sediment layers affect the flow efficiency of rainwater in the water storage component, hinder rainwater from entering the heat exchange structure of the ground source heat pump, resulting in high maintenance requirements for the ground source heat pump, and uneven water temperature distribution after the rainwater has been stagnant for a long time.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An energy-saving ground source heat pump includes a base and a water inlet plate. A heat pump unit is installed on top of the base. A circulation pipeline is connected to the outside of the heat pump unit. A water storage tank is connected to one side of the circulation pipeline. The side of the water storage tank away from the circulation pipeline is connected to a water storage tank via a guide pipe. A motor is installed on top of the water storage tank. The water inlet plate is connected to both sides of the water storage tank. Water inlets are opened on the inner walls of both sides of the water storage tank near the water inlet plate. A filter screen is installed in the inner cavity of the water storage tank near the water inlet. A collection port is provided on the inner side of the filter screen. A support plate is provided inside the water storage tank near the bottom of the filter screen. A guide ring is fixed below the support plate. A stirring mechanism is installed inside the water storage tank near the bottom of the guide ring. The stirring mechanism includes a first gear, a second gear, a second stirring rod, and a gear ring. A gear ring is fixed on the inner wall of the water storage tank. The first gear is meshed with the inner side of the gear ring. The second gear is meshed with one side of the first gear. The second stirring rod is fixedly connected below the first gear.

[0008] Preferably, a guide groove is provided on the inner side of the guide ring, and a support slider is slidably sleeved on the inner side of the guide groove, and the support slider is connected to the second stirring rod through a bearing.

[0009] Preferably, the support plate has water troughs on both sides, and the end of the motor near the inside of the water storage tank is connected to a stirring rod via a coupling.

[0010] Preferably, a cleaning push plate is connected to the outer side of the first stirring rod near the top of the filter screen, the second gear is fixedly sleeved with the first stirring rod, and guide plates are fixed on the inner walls of the water storage tank near the collection port on both sides.

[0011] Preferably, the water storage tank has outlets on both sides near the guide plate, the heat pump unit has an air outlet installed above it, and the heat pump unit has a dust suction plate installed above the center of the air outlet.

[0012] Preferably, a suction pipe is connected to one side of the dust suction plate, and an electric vacuum cleaner is connected to one side of the suction pipe. The electric vacuum cleaner is installed on one side of the heat pump unit, and cleaning mechanisms are installed on both sides of the heat pump unit near the air outlet.

[0013] Preferably, the cleaning mechanism, brush plate, electric push rod, rack and adjusting gear, and the electric push rod are connected to both sides of the heat pump unit via brackets.

[0014] Preferably, the output end of the electric push rod is connected to a rack, and an adjusting gear is meshed with one side of the rack.

[0015] Preferably, the heat pump unit has brush plates mounted on the outer surfaces of both sides near the adjusting gear via bearings, and one end of the brush plate is fixedly connected to the adjusting gear.

[0016] Preferably, the water-guiding plate is an arc structure, the flow guide plate is inclined, the water trough is an arc structure, and the cross-sectional shape of the guide groove is T-shaped.

[0017] Compared with the prior art, the beneficial effects of this invention are as follows: In this energy-saving ground source heat pump, rainwater enters the storage tank through the guide plate, and large particles of impurities are filtered out by the filter screen. The rainwater is collected in the storage tank. While the motor drives the first stirring rod to rotate, the stirring mechanism uniformly stirs the water, making the water temperature distribution uniform and improving the heat exchange efficiency. The first stirring rod drives the cleaning push plate to rotate, pushing the large particles of impurities on the surface of the filter screen to the collection port. Then, the large particles of impurities are discharged to the outside of the storage tank through the guide plate and the outlet. Driven by only one motor, the rainwater can be filtered and cleaned of large particles of impurities. Through stirring and scraping, the formation of sediment layer in the storage tank can be reduced, which is conducive to the rapid entry of the collected rainwater into the heat exchange structure of the ground source heat pump, improving the rainwater circulation efficiency. It can also make the temperature distribution of the stored rainwater uniform and prevent stratification. In addition, the cleaning mechanism can clean foreign objects and dust from the air outlet of the heat pump unit, improving the practicality and working efficiency of the ground source heat pump.

[0018] 1. This energy-saving ground source heat pump uses an inclined plate to guide water from the inlet into the storage tank. Due to the obstruction of the collection port by the cleaning push plate, rainwater carrying large particles such as leaves and pebbles falls onto the filter screen. The rainwater flows downwards through the filter screen's holes, while the leaves and large particles are blocked on the filter screen surface. The rainwater then flows downwards from the drain trough of the support plate, subsequently entering the lower part of the storage tank. When the motor is started, it drives the first stirring rod to rotate, which in turn drives the cleaning push plate to rotate, pushing the filter... Large particles of impurities rotate and move on the surface of the screen. When the large particles of impurities reach the collection port, they fall onto the guide plate due to gravity. Finally, the large particles of impurities slide out of the outlet through the inclined surface of the guide plate, thus discharging the large particles of impurities filtered by the screen into the water storage tank. This prevents large particles of impurities from continuing to accumulate in the water storage tank, eliminating the need for frequent cleaning by staff. It also prevents rainwater from carrying large particles of impurities into the filter of the ground source heat pump, reducing the workload on the ground source heat pump and extending its service life.

[0019] 2. This energy-saving ground source heat pump can simultaneously rotate and stir the water in the middle of the water body by driving the first stirring rod with the motor. The first stirring rod drives the second gear to rotate, and the second gear meshes with the first gear and is also connected to the gear ring. This causes the first gear to rotate around the center of the second gear, while the second gear moves in a circular trajectory along the gear ring. This, in turn, causes the second gear to drive the second stirring rod to rotate in a circular motion. One end of the second stirring rod drives the support slider to slide in the guide groove, which guides the second stirring rod. The second and first stirring rods work together, and with only one motor, the water body can be quickly mixed while cleaning large particles of impurities. Through stirring and scraping, the formation of sediment in the water storage tank can be reduced, preventing the sediment from affecting the flow efficiency of rainwater. This facilitates the rapid entry of collected rainwater into the heat exchange structure of the ground source heat pump, improving the rainwater flow efficiency, reducing energy consumption, and making the water temperature distribution more uniform, thus improving the cooling and heating cycle efficiency of the ground source heat pump.

[0020] 3. This energy-saving ground source heat pump periodically moves a rack by activating an electric push rod. The rack then meshes with an adjusting gear, causing the rack to rotate and the adjusting gear to rotate. The adjusting gear then rotates and swings a brush plate at the air outlet, clearing away foreign objects and brushing off dust. This loosening of dust is then facilitated by suction from an electric vacuum cleaner, which draws the loosened dust into the suction plate through the air inlet and then into the vacuum cleaner through the suction pipe. This process clears foreign objects from the air outlet while preventing dust from scattering, thus preventing air stagnation, promoting air circulation, and improving the air output efficiency of the ground source heat pump.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1-4 and Figure 10 The present invention provides a technical solution: an energy-saving ground source heat pump, including a base 1 and a water inlet plate 4. A heat pump unit 2 is installed on the top of the base 1. A circulation pipe 5 is connected to the outside of the heat pump unit 2. A water storage tank 6 is connected to one side of the circulation pipe 5. A water storage pool 7 is connected to the side of the water storage tank 6 away from the circulation pipe 5 through a guide pipe 21.

[0034] Please see Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 , Figure 9 and Figure 10The water-guiding plate 4 is connected to both sides of the water storage tank 7. The water storage tank 7 has water inlets 10 on both inner walls near the water-guiding plate 4. A filter screen 13 is installed in the inner cavity of the water storage tank 7 near the water inlet 10. A collection port 14 is opened on the inner side of the filter screen 13. A cleaning push plate 11 is connected to the outer side of the first stirring rod 12 near the filter screen 13. The second gear 902 is fixedly sleeved with the first stirring rod 12. A guide plate 26 is fixed on both inner walls of the water storage tank 7 near the collection port 14. A discharge port 25 is opened on both sides of the water storage tank 7 near the guide plate 26. The water-guiding plate 4 is designed with an arc structure. The guide plate 26 is designed with an inclined shape. The water trough 15 is designed with an arc structure. The cleaning push plate 11 is distributed in an X shape.

[0035] In practice, the ground source heat pump collects rainwater through the storage tank 7. The rainwater first falls into the water inlet plate 4, which guides the water from the inlet 10 into the storage tank 7 via its inclined surface. Due to the obstruction of the collection port 14 by the cleaning push plate 11, the rainwater carries large particles such as leaves or pebbles onto the filter screen 13. The rainwater flows downward through the filter holes of the filter screen 13, while the leaves or large particles are blocked on the surface of the filter screen 13. The rainwater then flows downward from the drain trough 15 of the support plate 16, and subsequently enters the lower part of the storage tank 7. When the motor 3 is started, the motor 3 drives the first stirring rod 1. 2. The first stirring rod 12 rotates, which in turn drives the cleaning push plate 11 to rotate. The cleaning push plate 11 pushes large particles of impurities on the surface of the filter screen 13 to rotate and move. When the large particles of impurities reach the position of the collection port 14, they fall onto the guide plate 26 due to gravity. Finally, the large particles of impurities slide out of the outlet 25 through the inclined surface of the guide plate 26, discharging the large particles of impurities filtered by the filter screen 13 into the water storage tank 7. This can prevent large particles of impurities from continuing to accumulate in the water storage tank 7, eliminating the need for frequent cleaning by staff, reducing the workload on the ground source heat pump, and extending the service life of the ground source heat pump.

[0036] Please see Figure 1 , Figure 2 and Figures 4-8A motor 3 is installed on the top of the water storage tank 7. A support plate 16 is located inside the water storage tank 7 near the bottom of the filter screen 13. A guide ring 17 is fixed below the support plate 16. A stirring mechanism 9 is installed inside the water storage tank 7 near the bottom of the guide ring 17. The stirring mechanism 9 includes a first gear 901, a second gear 902, a second stirring rod 903, and a gear ring 904. A gear ring 904 is fixed on the inner wall of the water storage tank 7. The inner side of the gear ring 904 is meshed with the first gear 901. A second gear 902 is meshed with one side of the first gear 901. A second stirring rod 903 is fixedly connected below the first gear 901. A guide groove 18 is provided on the inner side of the guide ring 17. A support slider 19 is slidably sleeved on the inner side of the guide groove 18. The support slider 19 and the second stirring rod 903 are connected by a bearing. Water troughs 15 are provided on both sides of the support plate 16. One end of the motor 3 near the inside of the water storage tank 7 is connected to a first stirring rod 12 through a coupling. The cross-sectional shape of the guide groove 18 is T-shaped.

[0037] In practice, after rainwater enters the lower part of the storage tank 7 for storage, the rainwater will stratify, resulting in uneven water temperature distribution. Simultaneously, the motor 3 drives the first stirring rod 12 to rotate and stir the water in the middle, while the first stirring rod 12 drives the second gear 902 to rotate. The second gear 902 then meshes with the first gear 901, and the second gear 902 meshes with the gear ring 904, causing the first gear 901 to rotate around the center of the second gear 902. At the same time, the second gear 902 moves in a circular trajectory along the gear ring 904, thereby driving the second stirring rod 903 to... The second stirring rod 903 rotates in a circular motion, and one end of the second stirring rod 903 drives the support slider 19 to slide in the guide groove 18. The guide groove 18 guides the second stirring rod 903. The second stirring rod 903 and the first stirring rod 12 move in coordination. Only one motor 3 is needed to clean large particles of impurities and quickly mix the water. Through stirring and scraping, the formation of sediment in the water storage tank 7 can be reduced, avoiding the sediment affecting the flow efficiency of rainwater. This is conducive to the rapid entry of collected rainwater into the heat exchange structure of the ground source heat pump, reducing energy consumption, and making the water temperature distribution uniform, thereby improving the cooling and heating cycle efficiency of the ground source heat pump.

[0038] Please see Figures 1-3An air outlet 22 is installed above the heat pump unit 2. A dust suction plate 20 is installed above the center of the heat pump unit 2 near the air outlet 22. A dust suction pipe 23 is connected to one side of the dust suction plate 20, and an electric vacuum cleaner 24 is connected to one side of the dust suction pipe 23. The electric vacuum cleaner 24 is installed on one side of the heat pump unit 2. Cleaning mechanisms 8 are installed on both sides of the heat pump unit 2 near the air outlet 22. The cleaning mechanism 8 includes a brush plate 801, an electric push rod 802, a rack 803, and an adjusting gear 80. 4. Both sides of the heat pump unit 2 are connected to electric push rods 802 via brackets. The output end of the electric push rod 802 is connected to a rack 803. One side of the rack 803 is meshed with an adjusting gear 804. Brush plates 801 are mounted on the outer surfaces of the heat pump unit 2 near the adjusting gear 804 via bearings. One end of the brush plate 801 is fixedly connected to the adjusting gear 804. The bristles on the brush plate 801 are made of nylon. An air inlet is provided on the outer side of the dust suction plate 20.

[0039] In practical implementation, since the air outlet 22 of the ground source heat pump is usually exposed, some foreign objects or dust can easily fall onto the mesh plate of the air outlet 22. Long-term accumulation will obstruct air circulation and cause local air stagnation. The rack 803 can be moved periodically by starting the electric push rod 802. Then the rack 803 meshes with the adjusting gear 804, causing the rack 803 to drive the adjusting gear 804 to rotate. The adjusting gear 804 then drives the brush plate 801 to rotate and swing at the air outlet 22, pushing away foreign objects at the air outlet 22 and brushing off the dust at the air outlet 22, making the dust loose. At the same time, the suction generated by the electric vacuum cleaner 24 makes the loose dust enter the dust suction plate 20 from the air inlet of the dust suction plate 20, and then enter the electric vacuum cleaner 24 through the suction pipe 23. This can not only push away foreign objects at the air outlet 22, but also prevent dust from flying around, prevent air stagnation, promote air circulation, and improve the air output efficiency of the ground source heat pump.

[0040] In summary, the heat pump unit 2 exchanges heat through the circulation pipe 5, and the water storage tank 6 can temporarily store water for circulation. Rainwater is guided into the water storage tank 7 through the water inlet plate 4, and large particles are filtered by the filter screen 13 to prevent them from entering the heat pump unit 2. The rainwater stored in the water storage tank 7 provides water for heat exchange. While the motor 3 drives the first stirring rod 12 to rotate, it also drives the stirring mechanism 9 to stir the water evenly, so that the temperature distribution is uniform. Large particles are discharged from the water storage tank 7 by the cleaning push plate 11. When foreign objects or dust accumulate at the air outlet 22, the cleaning mechanism 8 and the electric vacuum cleaner 24 are used to remove and clean the foreign objects and dust, which improves the practicality of the ground source heat pump. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
