Description

Technical Field

[0001] The present invention relates to the technical field of ground source heat pumps, in particular to an energy-saving ground source heat pump. Background Art

[0002] A geothermal heat pump uses ground energy as a cooling source for cooling in summer and a low-temperature heat source for heating in winter. It is also a system that achieves heating, cooling and domestic hot water. It is used to replace the traditional mode of using refrigerators and boilers for air conditioning, heating and heating. It is an effective way to improve the urban atmospheric environment and save energy. The geothermal heat pump system includes an outdoor geothermal heat exchange system, a water source heat pump unit and an indoor heating and air conditioning terminal system. The working principle of the geothermal heat pump is relatively simple. During summer operation, the evaporator of the heat pump unit absorbs heat from the building and reaches the condenser. At the same time, the condenser discharges the heat to the ground through heat exchange with groundwater. During winter operation, the evaporator of the heat pump unit absorbs heat from groundwater as a heat source, and through the heat pump cycle, the condenser provides hot water to heat the building's interior.

[0003] In the existing geothermal heat pump technology, heat exchange is carried out with groundwater or surface water. Geothermal heat pumps can use rainwater for energy saving. Rainwater is usually collected through multiple water storage components. After rainwater enters the water storage components, since the rainwater contains a large amount of impurities, these impurities will adhere to the inner wall of the water storage components after being accumulated in the water storage components for a long time, forming a thick sediment layer. These sediment layers will affect the flow efficiency of rainwater in the water storage components, hinder rainwater from entering the heat exchange structure of the geothermal heat pump, resulting in large maintenance requirements for the geothermal heat pump. In addition, after the rainwater has been stagnant for a long time, the water temperature is prone to uneven distribution, affecting the hot and cold cycle efficiency of the geothermal heat pump.

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

[0009] Preferably, lower water tanks are provided on both sides of the support plate, and one end of the motor close to the inside of the water reservoir is connected to a stirring rod No. 1 through a coupling.

[0010] Preferably, the outer side of the No. 1 stirring rod near the filter screen is connected with a cleaning push plate, the No. 2 gear and the No. 1 stirring rod are fixedly connected, and guide plates are fixed on the inner walls on both sides of the water reservoir near the collection port.

[0011] Preferably, the water reservoir is provided with discharge ports on both sides close to the guide plate, an air outlet is installed above the heat pump unit, and a dust absorption plate is installed above the middle of the air outlet of the heat pump unit.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: in the energy-saving ground source heat pump, rainwater enters the water reservoir through the diversion of the water guide plate, and large particles of impurities are filtered through the filter screen. The rainwater is collected through the water reservoir, and while the motor drives the No. 1 stirring rod to rotate, the stirring mechanism evenly stirs the water body, so that the temperature distribution of the water body is uniform, and the heat exchange efficiency is improved. The No. 1 stirring rod drives the cleaning push plate to rotate, and pushes the large particles of impurities on the surface of the filter screen to the collection port, and then the large particles of impurities are discharged to the outside of the water reservoir through the guide plate and the discharge port. Only one motor drive is used, and when filtering and cleaning the large particles of impurities in the rainwater, by stirring and scraping, the formation of sediment layers in the water reservoir can be reduced, which is conducive to the collected rainwater to quickly enter the heat exchange structure of the ground source heat pump, thereby improving the rainwater circulation efficiency, and also making the stored rainwater temperature evenly distributed to prevent stratification. In addition, the cleaning mechanism can clean foreign matter and dust at the air outlet of the heat pump unit, thereby improving the practicality and working efficiency of the ground source heat pump.

[0018] 1. For this energy-saving ground source heat pump, the water guide plate guides water from the water inlet into the water storage tank through the inclined surface. Due to the shielding of the collection port by the cleaning push plate, rainwater carrying large impurities such as leaves or stones falls on the filter screen, and the rainwater flows downward from the filter holes of the filter screen. The leaves or large impurities are blocked on the surface of the filter screen, and the rainwater flows downward from the lower water tank of the support plate, and then the rainwater enters the lower part of the water storage tank. When the motor is started, the motor drives the No. 1 stirring rod to rotate, and the No. 1 stirring rod drives the cleaning push plate to rotate, and the cleaning push plate pushes the filter screen. The large particles of impurities on the surface of the net rotate and move. When the large particles of impurities reach the position of the collection port, they fall onto the guide plate due to gravity, and finally slide out of the discharge port through the inclined surface of the guide plate, and the large particles of impurities filtered by the filter are discharged into the water reservoir, which can prevent the large particles of impurities from continuing to accumulate in the water reservoir. There is no need for frequent cleaning by staff, and rainwater can be prevented from carrying large particles of impurities into the filter of the ground source heat pump, which reduces the workload on the ground source heat pump and extends the service life of the ground source heat pump.

[0019] 2. The energy-saving ground source heat pump can drive the No. 1 stirring rod to rotate and stir in the middle of the water body while the No. 1 stirring rod drives the No. 2 gear to rotate, and the No. 2 gear is meshed with the No. 1 gear, and the No. 2 gear is meshed with the gear ring, so that the No. 1 gear rotates around the center of the No. 2 gear, and the No. 2 gear moves along the gear ring in a circular trajectory, so that the No. 2 gear drives the No. 2 stirring rod to perform a circular motion and rotate, and one end of the No. 2 stirring rod drives the supporting slider to slide in the guide groove, and the guide groove guides the No. 2 stirring rod, and the No. 2 stirring rod and the No. 1 stirring rod move in coordination with each other. Only one motor is used to clean large particles of impurities and quickly mix the water body. By stirring and scraping, the generation of sediment layers in the water reservoir can be reduced, and the sediment layers can be prevented from affecting the flow efficiency of rainwater, which is conducive to the rapid entry of the collected rainwater into the heat exchange structure of the ground source heat pump, thereby improving the rainwater circulation efficiency, reducing energy consumption, and making the water body temperature evenly distributed, thereby improving the cold and hot cycle efficiency of the ground source heat pump;

[0020] 3. The energy-saving ground-source heat pump regularly starts the electric push rod to push the rack to move, and then the rack meshes with the adjusting gear, so that the rack drives the adjusting gear to rotate, and the adjusting gear drives the brush plate to rotate and swing at the air outlet, so as to push away foreign objects at the air outlet and brush off the dust at the air outlet to loosen the dust. At the same time, suction is generated by the electric vacuum cleaner, so that the loosened dust enters the ash absorption plate from the air inlet of the ash absorption plate, and then enters the electric vacuum cleaner through the dust suction pipe, which can prevent dust from flying around while pushing away foreign objects at the air outlet and prevent air stagnation, which is beneficial to air circulation and improves the air outlet efficiency of the ground-source heat pump.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] During specific implementation, the ground source heat pump collects rainwater through the water reservoir 7. The rainwater first falls into the water guide plate 4. The water guide plate 4 guides water from the water inlet 10 into the interior of the water reservoir 7 through the inclined surface. Due to the shielding of the collection port 14 by the cleaning push plate 11, the rainwater carries large particles of impurities such as leaves or stones and falls on the filter screen 13. The rainwater flows downward from the filter holes of the filter screen 13. The leaves or large particles of impurities are blocked on the surface of the filter screen 13. The rainwater then flows downward from the lower water trough 15 of the support plate 16, and then the rainwater enters the lower half of the water reservoir 7. When the motor 3 is started, the motor 3 drives the No. 1 stirring rod 1 2 rotates, the stirring rod 12 drives the cleaning push plate 11 to rotate, and the cleaning push plate 11 pushes the 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 collecting port 14, the large particles of impurities fall onto the guide plate 26 due to gravity, and finally the large particles of impurities slide out of the discharge port 25 through the inclined surface of the guide plate 26, and the large particles of impurities filtered by the filter screen 13 are discharged from the water reservoir 7, which can prevent the large particles of impurities from continuing to accumulate in the water reservoir 7, and there is no need for frequent cleaning by the staff, and the workload on the ground source heat pump is reduced, thereby extending the service life of the ground source heat pump.

[0036] See also Figure 1 , Figure 2 and Figure 4-Figure 8A motor 3 is installed on the top of the water reservoir 7, a support plate 16 is provided inside the water reservoir 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 reservoir 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 reservoir 7, the inner side of the gear ring 904 is meshed with the first gear 901, the first gear 901 is connected to the inner side of the gear ring 904, and the first gear 901 is connected to the inner side of the gear ring 904. A No. 2 gear 902 is meshedly connected to one side of the No. 1 gear 901, and a No. 2 stirring rod 903 is fixedly connected to the lower side of the No. 1 gear 901. A guide groove 18 is provided on the inner side of the guide ring 17, and a support slider 19 is slidably sleeved on the inner side of the guide groove 18, and the support slider 19 is connected to the No. 2 stirring rod 903 through a bearing. Lower water tanks 15 are provided on both sides of the support plate 16, and the end of the motor 3 close to the inside of the water reservoir 7 is connected to the No. 1 stirring rod 12 through a coupling, and the cross-sectional shape of the guide groove 18 is set to be T-shaped.

[0037] In specific implementation, after rainwater enters the lower part of the water reservoir 7 for storage, the rainwater will be stratified, resulting in uneven temperature distribution of the water body. At the same time, the motor 3 can drive the No. 1 stirring rod 12 to rotate and stir in the middle of the water body, while the No. 1 stirring rod 12 drives the No. 2 gear 902 to rotate, and the No. 2 gear 902 is meshed with the No. 1 gear 901, and the No. 2 gear 902 is meshed with the gear ring 904, so that the No. 1 gear 901 rotates around the center of the No. 2 gear 902, and the No. 2 gear 902 moves in a circular trajectory along the gear ring 904, so that the No. 2 gear 902 drives the No. 2 stirring rod 903 to rotate. Circular motion and rotation, one end of the No. 2 stirring rod 903 drives the supporting slider 19 to slide in the guide groove 18, and the guide groove 18 guides the No. 2 stirring rod 903. The No. 2 stirring rod 903 and the No. 1 stirring rod 12 cooperate with each other to move. Only one motor 3 is used to clean large particles of impurities and quickly mix the water. By stirring and scraping, the formation of sediment layer in the water reservoir 7 can be reduced, and the sediment layer can be prevented from affecting the flow efficiency of rainwater, which is conducive to the collected rainwater to quickly enter the heat exchange structure of the ground source heat pump, reducing energy consumption, and making the water temperature evenly distributed, thereby improving the cold and hot cycle efficiency of the ground source heat pump.

[0038] See also Figure 1-Figure 3The heat pump unit 2 is provided with an air outlet 22 above, and a dust collecting plate 20 is provided above the middle of the air outlet 22 of the heat pump unit 2.

[0039] During specific implementation, since the air outlet 22 of the ground source heat pump is usually exposed to the outside, some foreign matter or dust is easy to fall onto the mesh plate of the air outlet 22. Long-term accumulation will hinder air circulation and cause local air stagnation. The electric push rod 802 can be started regularly to push the rack 803 to move, and then the rack 803 is engaged with the adjusting gear 804, so that the rack 803 drives the adjusting gear 804 to rotate, and the adjusting gear 804 then drives the brush plate 801 to rotate and swing at the air outlet 22, so as to push away the foreign matter at the air outlet 22 and brush off the dust at the air outlet 22 to loosen the dust. At the same time, suction is generated by the electric vacuum cleaner 24, so that the loosened dust enters the dust absorption plate 20 from the air inlet of the dust absorption plate 20, and then enters the electric vacuum cleaner 24 through the dust absorption pipe 23. While pushing away the foreign matter at the air outlet 22, dust can be prevented from flying around and air stagnation can be prevented, which is beneficial to air circulation and improves the air outlet efficiency of the ground source heat pump.

[0040] To sum up, the heat pump unit 2 performs heat exchange through the circulation pipeline 5, the water tank 6 can temporarily store water for circulation, rainwater is drained into the water reservoir 7 through the water guide plate 4, and large particles of impurities are filtered through the filter 13 to prevent large particles of impurities from entering the heat pump unit 2.

While the motor 3 drives the No. 1 stirring rod 12 to rotate, it drives the stirring mechanism 9 to evenly stir the water so that the temperature distribution is uniform, and the large particles of impurities are discharged from the water reservoir 7 through the cleaning push plate 11. When foreign matter or dust accumulates at the air outlet 22, the cleaning mechanism 8 and the electric vacuum cleaner 24 are used to clear the foreign matter and dust, thereby improving the practicality of the ground source heat pump.
