Description

Technical Field

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

[0002] Ground source heat pump heating is a highly efficient, energy-saving, and environmentally friendly heating technology. It converts low-grade heat energy from shallow soil, groundwater, or surface water into directly usable high-grade heat energy through heat exchange. For example, Chinese patent application No. 202021889533.7, filed on September 2, 2020, describes an energy-saving ground source heat pump heating device. During operation, a motor drives a cooling fan blade through its shaft, generating airflow that cools the ground source heat pump inside the heat pump box. Simultaneously, the cooling cavity contains heat exchange fins. Because these fins have heat absorption capabilities, they retain the heat from inside the ground source heat pump box. Then, the heat inside the heat sink is blown outward by the air, thereby improving the heat dissipation effect of the ground source heat pump box. There is also a Chinese patent application with application number 202222142193.7 and application date of 2022-08-15, which describes a ground source heat pump heating device. When the motor is started, it can drive the worm gear to rotate, and through the first gear, it can drive the vertical rod and the fan blades to rotate as a whole. In this way, under the drive of the same motor, two sets of fan blades can be rotated and heat dissipated at the same time, reducing manufacturing costs and energy consumption. Furthermore, by using the back and forth movement of the air box inside the ground source heat pump, the rotating fan blades can be driven to perform heat dissipation work at different positions inside the ground source heat pump box, resulting in higher heat dissipation efficiency.

[0003] In the process of ground source heat pump heating, the heat pump unit is one of the most important devices. During use, the heat exchanger inside the unit may produce a small amount of condensate due to local temperature differences in heating mode. If drainage is not smooth or the outer casing is not properly sealed, the condensate may seep into the inner side of the casing, causing metal parts to rust. The device in the above application does not have a structure for quick cleaning and air-dried moisture prevention during use, which leads to a short service life of the unit and causes unnecessary trouble for the operation of the heat pump unit. Utility Model Content

[0004] The purpose of this utility model is to provide an energy-saving ground source heat pump heating device to solve the problem mentioned in the background art that the device lacks a structure for quick cleaning and wind-proofing during use, which leads to a short service life of the device and causes unnecessary trouble for the operation of the heat pump host.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving ground source heat pump heating device, comprising a heat pump host and a base plate, wherein the heat pump host is bolted to the upper surface of the base plate, and an upper connecting plate is fixedly connected to the upper surface of the heat pump host, and a connecting shaft is rotatably arranged inside the upper connecting plate, and a first fan is rotatably arranged inside the connecting shaft; a limiting post is fixedly connected to the upper surface of the base plate, and a cleaning plate is slidably arranged on the surface of the limiting post, and a fixing plate is fixedly connected to the upper surface of the cleaning plate; a rotating shaft is rotatably arranged inside the fixing plate, and a second fan is fixedly connected to the end of the rotating shaft.

[0006] Preferably, the rear side of the heat pump unit is protruding, and a motor is bolted to the protruding position on the rear side of the heat pump unit. The output end of the motor is fixedly connected to a threaded rod, and the threaded rod is threadedly connected to the cleaning plate.

[0007] Preferably, the cleaning plate surrounds the heat pump unit, and an opening is provided on the left side of the cleaning plate.

[0008] Preferably, a traction rope is fixedly connected to the upper surface of the cleaning plate, and the other side of the traction rope is wrapped and fixedly connected to the surface of the connecting shaft, and the end of the connecting shaft is protruding.

[0009] Preferably, a torsion spring is fixedly connected to the surface of the connecting shaft, and the other side of the torsion spring is fixedly connected to the inner wall of the upper connecting plate. The first fan is symmetrically distributed on both sides of the heat pump host.

[0010] Preferably, a rack is fixedly connected to the upper surface of the base plate, and a gear that meshes with the rack is fixedly connected to the surface of the rotating shaft.

[0011] Preferably, the second fan is symmetrically distributed on both sides of the heat pump host.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This energy-saving ground source heat pump heating device adopts a novel structural design, the specific details of which are as follows: This energy-saving ground source heat pump heating device intermittently starts the motor during operation, causing the motor to drive the cleaning plate to reciprocate vertically via the threaded rod and limit post. The cleaning plate sweeps away the dust on the surface of the heat pump unit, preventing impurities from corroding the heat pump unit. During this process, the connecting shaft and the first fan are rotated under the action of the traction rope and torsion spring. In turn, the first fan blows away the water vapor, preventing water vapor from condensing and extending the service life of the heat pump unit's casing.

[0013] Furthermore, the first fan is symmetrically distributed on both sides of the heat pump unit, which optimizes the efficiency of moisture removal and makes the heat pump unit less susceptible to corrosion.

[0014] In this energy-saving ground source heat pump heating device, when the cleaning plate descends, the cleaning plate will drive the connecting shaft to rotate via the traction rope. At this time, the connecting shaft will release the traction rope, and the torsion spring will be stretched by the connecting shaft. When the cleaning plate rises, the connecting shaft will rotate under the action of the torsion spring, and the connecting shaft will rewind the traction rope for easy reuse of the connecting shaft and traction rope.

[0015] In this energy-saving ground source heat pump heating device, when the cleaning plate rises, the rotating shaft rotates inside the fixed plate under the action of the rack and gear. When the cleaning plate falls, the rotating shaft is in a rotary state, which drives the second fan to rotate. The second fan also plays the role of accelerating air flow, so that water vapor is carried away and does not condense on the surface of the heat pump unit.

[0016] Furthermore, the second fan moves vertically during operation, resulting in a wide working range and high efficiency. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides the following technical solution: an energy-saving ground source heat pump heating device.

[0021] Example 1: The motor 2 and cleaning plate 5 are used to clean the dust on the surface of the heat pump unit 1. Simultaneously, the first fan 9 prevents water vapor from condensing on the surface of the heat pump unit 1. Figures 1-5 As shown, the device includes a heat pump host 1 and a base plate 6. The heat pump host 1 is bolted to the upper surface of the base plate 6, and an upper connecting plate 7 is fixedly connected to the upper surface of the heat pump host 1. A connecting shaft 8 is rotatably arranged inside the upper connecting plate 7, and a first fan 9 is rotatably arranged inside the connecting shaft 8. A limiting post 4 is fixedly connected to the upper surface of the base plate 6, and a cleaning plate 5 is slidably arranged on the surface of the limiting post 4. A fixing plate 12 is fixedly connected to the upper surface of the cleaning plate 5. The rear side of the heat pump host 1 is protruding, and a motor 2 is bolted to the protruding position on the rear side of the heat pump host 1. A threaded rod 3 is fixedly connected to the output end of the motor 2, and the threaded rod 3 is threadedly connected to the cleaning plate 5.

[0022] The cleaning plate 5 surrounds the heat pump host 1, and an opening is provided on the left side of the cleaning plate 5. A traction rope 10 is fixedly connected to the upper surface of the cleaning plate 5, and the other side of the traction rope 10 is wrapped and fixedly connected to the surface of the connecting shaft 8. The end of the connecting shaft 8 is protruding. A torsion spring 11 is fixedly connected to the surface of the connecting shaft 8, and the other side of the torsion spring 11 is fixedly connected to the inner wall of the upper connecting plate 7. The first fan 9 is symmetrically distributed on both sides of the heat pump host 1.

[0023] During operation, the motor 2 on the surface of the heat pump unit 1 is intermittently activated. The motor 2, via the threaded rod 3 and the limiting post 4, drives the cleaning plate 5 to reciprocate vertically. The cleaning plate 5 cleans the dust from the surface of the heat pump unit 1, preventing impurities from corroding it. When the cleaning plate 5 descends, it drives the connecting shaft 8 to rotate inside the upper connecting plate 7 via the traction rope 10. At this time, the connecting shaft 8 releases the traction rope 10, and simultaneously, the torsion spring 11 is stretched by the connecting shaft 8 (e.g., ...). Figure 3 As shown, when the cleaning plate 5 rises, the connecting shaft 8 rotates under the action of the torsion spring 11. At this time, the connecting shaft 8 will retract the traction rope 10, which is convenient for the next use of the connecting shaft 8 and the traction rope 10. During the rotation of the connecting shaft 8, the first fan 9 rotates synchronously. At this time, the first fan 9 plays a role in assisting to dry the water vapor and prevent the water vapor from condensing. The first fan 9 is symmetrically distributed on both sides of the heat pump host 1, which optimizes the blowing effect.

[0024] Example 2: Unlike Example 1, the second fan 14 serves to assist in drying moisture, such as... Figure 5 and Figure 6As shown, a rotating shaft 13 is rotatably arranged inside the fixed plate 12, and a second fan 14 is fixedly connected to the end of the rotating shaft 13. A rack 15 is fixedly connected to the upper surface of the base plate 6, and a gear 16 that meshes with the rack 15 is fixedly connected to the surface of the rotating shaft 13. The second fan 14 is symmetrically distributed on both sides of the heat pump host 1.

[0025] As the cleaning plate 5 rises, the rotating shaft 13 rotates inside the fixed plate 12 under the action of the rack 15 and the gear 16 (e.g., Figure 6 As shown), when the cleaning plate 5 descends, the rotating shaft 13 is in a rotating state, that is, the rotating shaft 13 will drive the second fan 14 to rotate. At this time, the second fan 14 also plays the role of accelerating the air flow, so that the water vapor is carried away and does not condense on the surface of the heat pump host 1. At the same time, when the second fan 14 is working, it is also in a vertical direction, with a wide working range and high working efficiency.

[0026] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
