Description

Technical Field

[0001] This utility model relates to the field of heat pump technology, specifically a ground source heat pump. Background Technology

[0002] Ground source heat pumps are a new type of energy utilization technology that uses shallow geothermal energy for heating and cooling. They are a type of heat pump. Heat pumps are devices that transfer heat and cold using the Carnot cycle and reverse Carnot cycle principles. Ground source heat pumps typically refer to devices that can transfer heat or cold from the underground soil to the required location. Heat pumps are usually used for air conditioning or heating. Ground source heat pumps also utilize the huge heat and cold storage capacity of the underground soil. In winter, the ground source transfers heat from the underground soil to the building, and in summer, it transfers cold from the underground to the building, forming a heating and cooling cycle every year.

[0003] A ground source heat pump, as described in application number 202420841743.0, includes a ground source heat pump body. An installation assembly for disassembling and assembling the support side plate is installed inside the ground support base. When the worm gear is rotated forward, the displacement plate can move the positioning block outward synchronously and separate it from the positioning groove, allowing the ground source heat pump body to be disassembled. During the use of the ground source heat pump body, the shock-absorbing seat can buffer most of the vibration transmitted from the support base, and the vibration isolation pad can also prevent resonance noise between the fixed base plate and the external ground, thereby reducing resonance noise during the operation of the ground source heat pump body. However, the unit's ventilation and heat dissipation are not very flexible, and the opening size of the ventilation and heat dissipation holes cannot be adjusted. Utility Model Content

[0004] The purpose of this utility model is to provide a ground source heat pump to solve the problem that the ventilation and heat dissipation of existing units is not flexible and the opening size of the ventilation and heat dissipation holes cannot be adjusted.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ground source heat pump, including a base plate, a ground source heat pump unit on the upper side of the base plate, the ground source heat pump unit including a compressor, an evaporator and a condenser, a fan coil unit connected to the condenser, a heat exchange tube buried underground at one end of the evaporator, a protective cover on the outside of the ground source heat pump unit, a ventilation and heat dissipation frame hinged to the openings on both sides of the protective cover via hinge seats, a sealing baffle rotatably mounted inside the ventilation and heat dissipation frame via a rotating shaft, and multiple sealing baffles and rotating shafts arranged longitudinally, a motor connected to one end of the rotating shaft via a belt flywheel assembly, pulleys mounted on the lower sides of both ends of the base plate via lower supports, and a stabilizing support at both ends of the base plate.

[0006] Furthermore, a cooling fan is provided at the top inside the protective cover, and multiple cooling fans are provided.

[0007] Furthermore, the sealing baffle is provided with sealing strips on both sides, and the sealing strips are configured as semi-cylindrical rubber bodies.

[0008] Furthermore, the belt flywheel assembly includes a first belt flywheel assembly disposed between adjacent rotating shafts, and one end of the rotating shaft is also connected to the motor via a second belt flywheel assembly.

[0009] Furthermore, the motor is fixedly installed on the upper side of one end of the ventilation and heat dissipation frame, and a protective cover is provided on the upper side of the motor and the belt flywheel assembly.

[0010] Furthermore, the stabilizing bracket includes a lifting bracket that is longitudinally inserted into both ends of the base plate. The lower end of the lifting bracket is provided with a bottom support plate and anti-slip ribs. The upper end of the lifting bracket is threadedly connected to a screw on the upper part of the base plate. One end of the screw is vertically rotated and mounted on the upper part of the base plate through a bearing.

[0011] Furthermore, a temperature sensor is provided on the inner wall of the protective cover, and both the temperature sensor and the motor are electrically connected to a controller outside the protective cover via wires.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model features a sealing baffle inside the ventilation and heat dissipation frame that rotates via a shaft. One end of the shaft is connected to an electric motor via a belt and flywheel assembly. This allows the size of the opening in the ventilation and heat dissipation frame to be adjusted by driving the shaft to rotate via the electric motor and the belt and flywheel assembly. Furthermore, when the ground source heat pump unit is not in operation, the ventilation and heat dissipation frame can be sealed and protected, thus improving the flexibility of the unit's ventilation and heat dissipation.

[0014] This utility model features pulleys on the lower sides of both ends of the base plate via lower supports, facilitating the movement and handling of the unit. Furthermore, both ends of the base plate are equipped with stabilizing supports, including lifting supports longitudinally inserted into the interior of both ends of the base plate. The lower end of the lifting support has a bottom support plate, and the upper end of the lifting support is threadedly connected to a screw on the upper part of the base plate. This allows for the adjustment of the lifting support and bottom support plate by rotating the screw. When the bottom support plate is pressed onto the ground, the pulleys can be removed from the ground, improving the stability of the lower support of the base plate.

[0015] This invention features a temperature sensor installed on the inner wall of the protective casing. Both the temperature sensor and the motor are electrically connected to a controller outside the protective casing via wires. The temperature sensor detects the temperature inside the protective casing. When the temperature inside the casing is high, the temperature sensor transmits a signal to the controller. The controller then drives the motor and belt flywheel assembly to rotate the shaft, thereby increasing the ventilation opening of the heat dissipation frame. Conversely, rotating the shaft in the opposite direction decreases the ventilation opening, thus improving the flexibility of heat dissipation. Attached Figure Description

[0022] 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.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4In this embodiment of the utility model, a ground source heat pump includes a base plate 1. A ground source heat pump unit is provided on the upper side of the base plate 1. The ground source heat pump unit includes a compressor 9, an evaporator 23, and a condenser 24. A fan coil unit is connected to the outside of the condenser 24. A heat exchange tube buried underground is provided at one end of the evaporator 23. A protective cover 2 is provided on the outside of the ground source heat pump unit. A cooling fan 3 is provided at the top inside the protective cover 2. Multiple cooling fans 3 are provided to facilitate air cooling of the ground source heat pump unit. Ventilation and heat dissipation frames 5 are hinged to the openings 4 on both sides of the protective cover 2 through hinge seats 6. A sealing baffle 7 is rotatably provided inside the ventilation and heat dissipation frame 5 through a rotating shaft 16. The sealing baffle 7 and the rotating shaft 16 are connected to each other. Multiple shafts 16 are arranged longitudinally. One end of the shaft 16 is connected to a motor 20 via a belt flywheel assembly. The belt flywheel assembly includes a first belt flywheel assembly 19 disposed between adjacent shafts 16. One end of the shaft 16 is also connected to the motor 20 via a second belt flywheel assembly 21. The motor 20 is fixedly mounted on the upper side of one end of the ventilation and heat dissipation frame 5. The upper side of the motor 20 and the belt flywheel assembly is provided with a protective cover, so that the opening size of the ventilation and heat dissipation frame 5 can be adjusted by rotating the shaft 16 driven by the motor 20 and the belt flywheel assembly. Moreover, when the ground source heat pump unit is not working, the ventilation and heat dissipation frame 5 can be sealed and protected, which improves the flexibility of the unit's ventilation and heat dissipation.

[0024] like Figure 1 and Figure 2 As shown, in order to improve the stability of the lower support of the base plate 1, pulleys 10 are provided on the lower side of both ends of the base plate 1 via the lower bracket 8, which facilitates the movement and handling of the unit. The base plate 1 is also provided with a stabilizing bracket at both ends. The stabilizing bracket includes a lifting bracket 12 that is longitudinally inserted into the interior of both ends of the base plate 1. The lower end of the lifting bracket 12 is provided with a bottom support plate 11 and an anti-slip rib 13. The upper end of the lifting bracket 12 is threadedly connected to the screw 15 on the upper part of the base plate 1. One end of the screw 15 is vertically rotatably mounted on the upper part of the base plate 1 through a bearing 14, so that the lifting bracket 12 and the bottom support plate 11 can be adjusted by rotating the screw 15. When the bottom support plate 11 is pressed on the ground, the pulleys 10 can be lifted off the ground, thereby improving the stability of the lower support of the base plate 1.

[0025] like Figure 2 and Figure 3 As shown, sealing strips 18 are also provided on both sides of the sealing baffle 7, and the sealing strips 18 are set as semi-cylindrical rubber bodies, which facilitates the elastic closure between adjacent sealing baffles 7 and helps to improve the sealing performance when the sealing baffle 7 is closed.

[0026] like Figure 1 and Figure 4As shown, in order to improve the flexibility of heat dissipation, a temperature sensor 22 is also provided on the inner wall of the protective cover 2. The temperature sensor 22 and the motor 20 are electrically connected to the controller 17 outside the protective cover 2 through wires. The temperature sensor 22 is used to detect the temperature inside the protective cover 2. When the temperature inside the protective cover 2 is high, the temperature sensor 22 transmits the signal to the controller 17. The controller 17 drives the motor 20 and the belt flywheel assembly to rotate the shaft 16 to adjust the opening 4 of the ventilation heat dissipation frame 5. Conversely, rotating the shaft 16 in the opposite direction can reduce the opening 4 of the heat dissipation frame, thus improving the flexibility of heat dissipation.

[0027] The working principle and usage process of this utility model are as follows: When in use, the ventilation and heat dissipation frame 5 is hinged to the outside of the openings 4 on both sides of the protective cover 2 through the hinge seat 6. The ventilation and heat dissipation frame 5 is equipped with a sealing baffle 7 through the rotating shaft 16 inside. The opening size of the ventilation and heat dissipation frame 5 can be adjusted by driving the rotating shaft 16 to rotate through the motor 20 and the belt flywheel group. Moreover, when the ground source heat pump unit is not working, the ventilation and heat dissipation frame 5 can be sealed and protected, which improves the flexibility of the unit's ventilation and heat dissipation.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
