Description

Technical Field

[0001] The utility model relates to the technical field of ground source heat pumps, and more specifically, to an automatic temperature control device for a ground source heat pump. Background Art

[0002] The ground source heat pump system is an advanced heating and air conditioning method with high energy efficiency and no pollution. In the field of building energy consumption, it is a new technology application project that is first recommended for environmental protection and energy conservation. In 2003, the Ministry of Construction listed the ground source heat pump heating and air conditioning technology as a new building energy-saving technology achievement and vigorously promoted it. The application and promotion of the ground source heat pump technology will play a better positive role in protecting the environment, improving the environmental quality, and further promoting and implementing the Blue Sky Project.

[0003] In the Chinese utility model patent, such as the utility model of CN216694067U, an automatic temperature control device for a ground source heat pump is disclosed, which includes a temperature control box. When the temperature sensor detects that the temperature of the ground source water is lower than the set temperature of the controller, the coolant at an appropriate temperature will circulate and enter from the cold source medium inlet pipe and output from the cold source medium outlet pipe. Then, the ground source water inside the spiral pipe can be cooled to achieve automatic temperature control.

[0004] When the above technology is used, the temperature of the ground source water inside the spiral pipe is controlled by heating and cooling the spiral pipe to achieve automatic temperature control. However, when cooling the spiral pipe, the coolant is transported through the cold source medium inlet pipe. When it enters the temperature control box, since the position of the cold source medium inlet pipe is fixed, it is necessary to fill the coolant inside the temperature control box to evenly cool the spiral pipe, which requires a large amount of coolant, resulting in waste of resources. At the same time, after the inside of the temperature control box is fully cooled, it will also affect the subsequent reheating of the fixed cylinder inside, consuming a large amount of resources, which does not conform to the concept of environmental protection and energy conservation. Summary of the Utility Model

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides an automatic temperature control device for a ground source heat pump. The technical problem to be solved by the utility model is that the cooling and reheating of the spiral pipe in the comparative technology consume a large amount of energy and do not conform to the concept of environmental protection and energy conservation.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A ground source heat pump automatic temperature control device includes a temperature control box. A water inlet box is fixedly installed on the outside of the temperature control box. A filtering mechanism is arranged in the water inlet box. A plurality of heating cylinders are fixedly installed in the temperature control box. A spiral pipe is installed on the outside of each heating cylinder. Two adjacent spiral pipes are communicated with each other. One of the spiral pipes is communicated with the water inlet box. A cooling box is fixedly installed on the outside of the temperature control box. An annular cooling pipe is installed inside the cooling box. One of the spiral pipes is communicated with the annular cooling pipe. A cleaning seat is slidably connected inside the cooling box. The cooling box drives the cleaning seat to slide through a driving structure. A plurality of cleaning brushes are installed on the inner side of the cleaning seat. A spray head is installed on the top wall of the cleaning seat. The top end of the spray head is fixedly connected and communicated with a coolant inlet pipe.

A water storage tank is fixedly installed on the outside of the temperature control box. One end of the annular cooling pipe is communicated with a connecting pipe. The connecting pipe penetrates through the cooling box and is connected with the water storage tank.

[0008] As Figures 1-5 shown, the specific implementation method is as follows: By setting the temperature control box and the heating cylinder, the flowing water in the spiral pipe can conduct heat transfer, thereby increasing the temperature of the flowing water. By setting the cooling box, the cooling of the flowing water in the spiral pipe is separated from the temperature control box, avoiding affecting the temperature in the temperature control box, and thus avoiding affecting the heating of the spiral pipe again. By setting the annular cooling pipe, the flowing time of the flowing water in the cooling box is increased. By setting the cleaning seat, the scale on the outside of the annular cooling pipe can be cleaned, avoiding the influence of scale accumulation on the heat transfer of the annular cooling pipe. By setting the spray head, the upper part of the annular cooling pipe can be slidably sprayed while the cleaning seat slides, so that the coolant evenly covers the surface of the annular cooling pipe, making the cooling more uniform. At the same time, the sliding spraying can increase the contact area and contact time between the coolant and the annular cooling pipe, thereby improving the cooling efficiency.

[0009] In a preferred embodiment, the driving structure includes a threaded rod, and the threaded rod is threadedly connected with the cleaning seat. A second limiting rod is fixedly installed in the cooling box, and the second limiting rod is slidably connected with the cleaning seat.

[0010] In a preferred embodiment, the filtering mechanism includes a filtering cylinder, and the filtering cylinder is threadedly connected in the water inlet box. A first limiting rod and a double-headed screw rod are respectively fixedly installed in the water inlet box. Two cleaning rings are symmetrically installed on the double-headed screw rod, and each cleaning ring is slidably connected with the first limiting rod. Each cleaning ring is sleeved on the outside of the filtering cylinder.

[0011] In a preferred embodiment, a threaded seat is fixedly installed on the outside of the filtering cylinder, and the threaded seat is threadedly connected in the temperature control box.

[0012] In a preferred embodiment, a first motor is fixedly installed on the top surface of the water inlet tank, and the output shaft of the first motor penetrates through the water inlet tank and is connected to a double-headed screw.

[0013] In a preferred embodiment, a second motor is fixedly installed on the outer side of the cooling tank, and the output shaft of the second motor penetrates through the cooling tank and is connected to a threaded rod.

[0014] In a preferred embodiment, the two threads of the double-headed screw have opposite directions, and the connection point of the two threads is located at the midpoint of the double-headed screw.

[0015] In a preferred embodiment, a ground source water inlet pipe is fixedly connected to the top surface of the water inlet tank. The coolant inlet pipe is made of a rubber hose, and a controller is fixedly installed on the outer side of the temperature control box.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. By setting devices such as a cooling tank and a temperature control box, the present utility model realizes the separation of the cooling and heating of the water inside the spiral tube, thereby avoiding affecting the temperature inside the temperature control box when cooling the spiral tube. Furthermore, when the spiral tube is reheated, there is no need to reheat the heating cylinder from the beginning, achieving the purpose of reducing energy consumption.

[0018] 2. By setting devices such as a threaded rod, a spray head, an annular cooling pipe, and a cleaning brush, the present utility model realizes the purpose that by rotating the threaded rod, the cleaning seat can be driven to slide, and then the spray head can be driven to slide, so that while the cleaning brush cleans the annular cooling pipe, the annular cooling pipe can be evenly cooled through the spray head, achieving the purpose of cleaning the scale on the outside of the annular cooling pipe, making the annular cooling pipe cooled evenly, and improving the cooling efficiency.

[0019] In summary, when the present utility model is in use, the operation is simple. The cooling and heating of the water inside the spiral tube are separated. Furthermore, when the spiral tube is reheated, there is no need to reheat the heating cylinder from the beginning, reducing energy consumption. At the same time, the scale on the outside of the annular cooling pipe can be cleaned, the annular cooling pipe can be cooled evenly, and the cooling efficiency is improved.

[0028] Such as Figures 1-5As shown, the implementation mode is specifically as follows: By setting up a temperature control box 1 and a heating cylinder 6, the flowing water in the spiral tube 7 can conduct heat transfer, thereby increasing the temperature of the flowing water. By setting up a cooling box 3, the cooling of the flowing water in the spiral tube 7 is separated from the temperature control box 1, avoiding affecting the temperature in the temperature control box 1, and thus avoiding affecting the heating of the spiral tube 7 again. By setting up an annular cooling tube 16, the flowing time of the flowing water in the cooling box 3 is increased. By setting up a cleaning seat 19, the scale on the outer side of the annular cooling tube 16 can be cleaned, avoiding the influence of scale accumulation on the heat transfer of the annular cooling tube 16. By setting up a nozzle 22, the upper part of the annular cooling tube 16 can be sprayed while the cleaning seat 19 slides, so that the coolant evenly covers the surface of the annular cooling tube 16, making the cooling more uniform. At the same time, the sliding spraying can increase the contact area and contact time between the coolant and the annular cooling tube 16, thereby improving the cooling efficiency.

[0029] The driving structure includes a threaded rod 23, and the threaded rod 23 is threadedly connected to the cleaning seat 19. A second limiting rod 24 is fixedly installed in the cooling box 3, and the second limiting rod 24 is slidably connected to the cleaning seat 19.

[0030] By rotating the threaded rod 23, the cleaning seat 19 is driven to slide. At the same time, the cleaning seat 19 is limited by the second limiting rod 24 so that it cannot rotate.

[0031] The filtering mechanism includes a filtering cylinder 10, and the filtering cylinder 10 is threadedly connected in the water inlet tank 2. A first limiting rod 11 and a double-headed screw rod 12 are respectively fixedly installed in the water inlet tank 2. Two cleaning rings 13 are symmetrically installed on the double-headed screw rod 12, and each cleaning ring 13 is slidably connected to the first limiting rod 11. Each cleaning ring 13 is sleeved on the outer side of the filtering cylinder 10.

[0032] It should be noted that by threadedly connecting the filtering cylinder 10 in the water inlet tank 2, it is convenient to quickly replace the filtering cylinder 10. By rotating the double-headed screw rod 12, the cleaning rings 13 can be driven to clean the impurities attached to the outer side of the filtering cylinder 10.

[0033] A threaded seat 14 is fixedly installed on the outer side of the filtering cylinder 10, and the threaded seat 14 is threadedly connected in the temperature control box 1.

[0035] A second motor 20 is fixedly installed on the outer side of the cooling box 3, and the output shaft of the second motor 20 penetrates through the cooling box 3 and is connected to the threaded rod 23.

[0038] Furthermore, the two cleaning rings 13 slide symmetrically to clean both the upper and lower sides of the filter cartridge 10.

[0040] When the present utility model is in use, first, ground source water enters through the ground source water inlet pipe 8, and then the water is filtered by the filter cartridge 10. At the same time, by starting the first motor 9, the double-headed screw rod 12 can be driven to rotate. Under the limitation of the first limiting rod 11, the two cleaning rings 13 slide on the outer side of the filter cartridge 10. At the same time, through the forward and reverse rotation of the first motor 9, the two cleaning rings 13 slide reciprocally, thereby cleaning the outer side of the filter cartridge 10 to prevent the filter cartridge 10 from being blocked. At the same time, the filter cartridge 10 is threadedly connected in the water inlet tank 2, which is convenient for disassembling and replacing the filter cartridge 10;

[0041] Then the water enters the temperature control box 1 through the spiral pipe 7 and exchanges heat with the heating cylinder 6, which can increase the temperature of the water in the spiral pipe 7. Then the water in the spiral pipe 7 flows to the annular cooling pipe 16. When cooling is required, coolant can enter through the coolant inlet pipe 15.
