Description

Technical Field

[0001] This utility model belongs to the field of geothermal heating technology, specifically, it relates to a geothermal heating heat pump unit. Background Technology

[0002] Geothermal heating, also known as floor radiant heating or geothermal radiant heating, requires the use of heat pump units. Geothermal heat pumps are environmentally friendly and pollution-free. The geothermal water source is used as the hot water for the heat pump. The hot water is first drawn up from the ground by the heat pump, then circulated in the user's home, and finally pumped back down into the ground. It is a complete cycle and an exchange with the underground. It is unrelated to the air temperature and is only affected by the geological environment. It is a renewable cycle.

[0003] A document with publication number (CN218627020U) discloses a geothermal heating heat pump unit, including a base plate, a top box on the top of the heat pump unit body, a floor heating pipe inside the top box, a delivery pipe between the heat pump unit body and the floor heating pipe, and two ends of the delivery pipe connected to the heat pump unit body and the delivery pipe respectively. A protective sleeve is provided on the outside of the delivery pipe, and a sponge sleeve is provided on the inner wall of the protective sleeve, abutting against the outer wall of the delivery pipe. An adhesive plate is provided on the surface of the protective sleeve, and a water outlet pipe is provided on the side of the floor heating pipe, connected to the floor heating pipe. The above device, through the combined use of the protective sleeve, adhesive plate, and sponge sleeve, can insulate the delivery pipe, preventing heat loss when transporting hot water, thereby increasing the temperature inside the floor heating pipe and improving the practicality of the heat pump unit in use.

[0004] In practical applications, although the device uses the periodic vertical vibration mechanism of the filter plate to remove surface impurities, it suffers from insufficient cleaning efficiency due to its one-dimensional motion mode. Affected by the coupling between the vibration mechanism and the fluid dynamics characteristics, a laminar boundary layer is easily formed inside the system, causing the average flow velocity of the water to drop to below 0.8 m / s. This not only exacerbates the risk of impurity deposition but also significantly restricts the overall processing efficiency of the filtration system.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0029] Please see Figure 1-5A geothermal heating heat pump unit includes a heat pump unit body 1, a connecting pipe 13 fixedly connected to the heat pump unit body 1, a housing 11 fixedly connected to the connecting pipe 13, and a water outlet pipe 12 fixedly connected to the side of the housing 11; a water pumping pipe 2, located at the bottom end of the heat pump unit body 1, and a cleaning component fixedly connected to the water pump unit body 1. The cleaning component is located inside the water pumping pipe 2 and is used to clean and accelerate the flow of groundwater. The cleaning component includes a filter plate 3, a turbine blade 41, and a movable block 51. The turbine blade 41 rotates... The filter plate 3 is installed inside the water pumping pipe 2 and is elastically connected to the inner wall of the water pumping pipe 2. The movable block 51 is arranged in an array between the filter plate 3 and the turbine blade 41. The movable block 51 is connected to the turbine blade 41 in a transmission manner. The heat pump unit body 1 pumps water upward with the help of the water pumping pipe 2. After the water passes through the water pumping pipe 2, the internal components of the cleaning component work together to fully remove impurities on the filter plate 3. After the water flows through, the turbine blade 41 is driven by the water flow. After the turbine blade 41 rotates and increases in speed, the flow rate of the water is increased.

[0030] The inner wall of the pumping pipe 2 is fixedly connected to an installation ring 4. The turbine blade 41 is rotatably connected to the installation ring 4. The bottom end of the turbine blade 41 is fixedly connected to a transmission rod 42. The movable block 51 is elastically connected to the transmission rod 42. Fixed blocks 5 are arranged in an array on the transmission rod 42, and each fixed block 5 is fixedly connected to the transmission rod 42. The corresponding movable block 51 is elastically connected to the fixed block 5. A second spring 52 is provided between each fixed block 5 and the movable block 51. The end of each second spring 52 is fixedly connected to the corresponding fixed block 5 and the movable block 51 respectively. After the water flows through the turbine blade 41, due to the turbulence effect and the tilted arrangement of the turbine blade 41, the water flow and the blade... The presence of a tangential striking mechanism drives the turbine blade 41 to rotate. The rotation of the turbine blade 41 applies pressure to the water flow, increasing the flow velocity and improving the heat exchange efficiency of the device. During rotation, the turbine blade 41 drives the transmission rod 42, which in turn drives the movable block 51. The movable block 51 rubs against the surface of the filter plate 3, removing dust from the filter plate 3. As the filter plate 3 rises and falls, it pushes the movable block 51, which compresses the second spring 52. The second spring 52 deforms and applies the deformation force to the movable block 51. The movable block 51 remains in close contact with the surface of the filter plate 3, constantly rubbing against the surface of the filter plate 3, thus improving the efficiency of dust removal from the filter plate 3.

[0031] The water pump pipe 2 has a sliding groove, and the filter plate 3 slides in the sliding groove. Multiple sets of first springs 31 are installed in the sliding groove, with the end of each first spring 31 fixedly connected to the filter plate 3 and the sliding groove. Each movable block 51 abuts against the filter plate 3, and the corresponding fixed block 5 is slidably connected to the movable block 51. A cleaning brush is fixedly connected to the bottom of each movable block 51. A buffer ring 32 is installed in the sliding groove on the inner wall of the water pump pipe 2, and the buffer ring 32 is fixedly connected to the sliding groove. The buffer ring 32 is also fixed to the filter plate. The bottom of the filter plate 3 is in contact with the water flow. After the water flow impacts the filter plate 3, the filter plate 3 compresses the first spring 31. The first spring 31 deforms and applies the deformation force to the filter plate 3. The filter plate 3 is pushed downward and then pushed upward by the water flow. The filter plate 3 is driven to move up and down repeatedly. The filter plate 3 vibrates against the inner wall of the water pumping pipe 2 and the buffer ring 32, which removes the dust on the filter plate 3. After the filter plate 3 comes into contact with the buffer ring 32, the buffer ring 32 cushions the filter plate 3, preventing the filter plate 3 from being damaged by continuous impact.

[0032] The box body 11 has a cavity, and a heating tube 14 is fixedly connected inside the cavity. Water is sent into the box body 11 through the connecting pipe 13, and the heating tube 14 exchanges heat with the water. The water after heat exchange is discharged through the water outlet pipe 12.

[0033] It is worth noting that the heat pump unit body 1 can extract groundwater; the heat pump unit body 1 has been disclosed in the prior art of a geothermal heating heat pump unit CN218627020U, and will not be described in detail here.

[0034] Working Principle: The heat pump unit body 1 pumps water upwards via the water suction pipe 2. After passing through the water suction pipe 2, the internal components of the cleaning assembly work together to thoroughly remove impurities from the filter plate 3. The turbine blades 41, driven by the water flow, increase the flow velocity as they rotate. Due to turbulence and the inclined blade design, the water flow and blades collide at an angle, causing the turbine blades 41 to rotate. This rotation provides pressure to the water flow, further increasing its velocity and improving the heat exchange efficiency. The rotating turbine blades 41 drive the transmission rod 42, which in turn drives the movable block 51. The movable block 51 rubs against the surface of the filter plate 3, removing dust. Furthermore, the rising and falling of the filter plate 3 pushes the movable block 51, compressing it. The second spring 52 deforms and applies the deformation force to the movable block 51. The movable block 51 is always in close contact with the surface of the filter plate 3, constantly rubbing against the surface of the filter plate 3, improving the efficiency of dust removal on the filter plate 3. After the water flow impacts the filter plate 3, the filter plate 3 compresses the first spring 31, which deforms and applies the deformation force to the filter plate 3. The filter plate 3 is pushed downward and then pushed upward by the water flow. The filter plate 3 is driven to move up and down repeatedly. The filter plate 3 vibrates against the inner wall of the water pumping pipe 2 and the buffer ring 32, removing the dust on the filter plate 3. After the filter plate 3 comes into contact with the buffer ring 32, the buffer ring 32 cushions the filter plate 3, preventing the filter plate 3 from being damaged by continuous impact. Water is sent into the box 11 through the connecting pipe 13. The heating pipe 14 heats the water flow. The water flow after heat exchange is discharged through the outlet pipe 12.
