Description

Technical Field

[0001] The utility model relates to the technical field of control cabinets, and specifically relates to a ground source heat pump control cabinet. Background Technique

[0002] A ground source heat pump is a technology that transfers low-grade heat energy to high-grade heat energy by inputting a small amount of high-grade energy (such as electric energy) from shallow terrestrial energy. Usually, when a ground source heat pump consumes 1 kWh of energy, users can obtain more than 4.4 kWh of heat or cooling capacity. The ground source heat pump technology belongs to the renewable energy utilization technology. Since the ground source heat pump uses the shallow geothermal resources on the earth's surface (usually less than 400 meters deep) as the heat and cold sources for an energy conversion heating and air conditioning system, the shallow geothermal resources on the earth's surface can be called geothermal energy, which refers to the low-grade thermal energy stored in the surface soil, groundwater, or rivers and lakes by absorbing solar energy and geothermal energy. The shallow surface of the earth is a huge solar collector that has collected 47% of the solar energy, which is more than 500 times the energy used by humans every year. It is not restricted by regions, resources, etc., and is truly large in quantity and widespread everywhere. This nearly infinite renewable energy stored in the shallow surface of the earth makes geothermal energy also become a form of clean renewable energy. When a ground source heat pump is in use, control equipment is required for operation, so a control cabinet is an essential supporting facility.

[0003] For example, the patent with the publication number CN209662491U discloses a ground source heat pump control cabinet, which includes a cabinet body. A control device is installed in the cabinet body. A vertical pipe is fixedly installed at the top inside the cabinet body. The lower end of the vertical pipe is open. A circular plate is fixedly installed in the middle and lower part inside the vertical pipe. A heat conducting plate is fixedly installed at the lower end of the vertical pipe. An elastic plate is arranged below the circular plate. The outer periphery of the elastic plate is fixedly connected to the inner wall of the vertical pipe. A first through hole is opened in the middle of the top surface of the circular plate. A piston shaft is fitted in the first through hole. Several uniformly distributed levers are arranged on the outer periphery of the upper end of the piston shaft. The inner ends of the levers are hinged to the side part of the upper end of the piston shaft. Several mounting rods are arranged on the outer periphery of the upper end of the piston shaft. It can automatically spray fire extinguishing agent when the parts inside the cabinet are overheated or on fire, and can automatically realize the prevention and automatic fire extinguishing work of the fire, effectively protecting the safety of the control device and ensuring the normal operation of the equipment.

[0004] Based on the retrieval of the patent number and combined with the deficiencies in the existing technology, it is found that although this ground source heat pump control cabinet can automatically spray fire extinguishing agent when the parts inside the cabinet are overheated or on fire and can automatically realize the prevention and automatic fire extinguishing work of the fire, when in use, although the fire extinguishing agent can achieve the fire extinguishing effect, after the fire extinguishing agent extinguishes the fire inside the main body of the control cabinet, the electronic components inside the main body of the control cabinet have been damaged, and a large-scale repair or direct scrapping is required inside the main body of the control cabinet. The main reason for the fire inside the main body of the control cabinet is excessive internal heat accumulation. Therefore, a heat dissipation structure should be added to the main body of the control cabinet to avoid the occurrence of fire caused by excessive internal heat accumulation in the main body of the control cabinet.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] As shown in Figures 1 to 4 , a ground source heat pump control cabinet provided by the present utility model includes a control cabinet main body 1 and heat dissipation holes 2.

A sealing component 4 is movably connected to the top on the right side of the control cabinet main body 1. A transmission component 5 is arranged at the top on the right side of the control cabinet main body 1.

[0024] Referring to Figure 3 , the sealing component 4 includes a sealing plate 41. The sealing plate 41 is located on the right side of the ventilation opening 3.

[0025] As a technical optimization scheme of the present utility model, by setting the sealing component 4, the sealing plate 41 can block the sealing opening, so as to avoid foreign objects from entering the interior of the control cabinet main body 1 when the ventilation opening 3 is not used for heat dissipation of the control cabinet main body 1. The support plate 42 can support the sealing plate 41. By pulling the moving plate 43 up and down, the sealing plate 41 can be driven to move up and down.

[0026] Referring to Figure 3 , the transmission component 5 includes a top plate 51, a servo motor 52 and a lead screw 53. The servo motor 52 is fixedly installed on the top of the top plate 51. The left side of the top plate 51 is fixedly connected to the right side of the control cabinet main body 1. The output end of the servo motor 52 is fixedly connected to one end of the lead screw 53. The other end of the lead screw 53 penetrates through the moving plate 43 and is movably connected to the top of the support plate 42 through a bearing. The lead screw 53 is threadedly connected to the moving plate 43.

[0027] As a technical optimization scheme of the present utility model, by setting the transmission component 5, the top plate 51 can support and fix the servo motor 52. By starting the servo motor 52, the output end of the servo motor 52 can drive the lead screw 53 to rotate. The rotation of the lead screw 53 can drive the moving plate 43 to move up and down.

[0028] Referring to Figure 4, limiting plates 6 are fixedly connected to both the front side and the rear side of the sealing plate 41. A fixing plate 7 is slidably connected to the surface of the limiting plate 6, and the left side of the fixing plate 7 is fixedly connected to the right side of the control cabinet main body 1.

[0029] As a technical optimization scheme of the present utility model, by providing the limiting plate 6 and the fixing plate 7, the fixing plate 7 can limit the limiting plate 6 in the front-back, left-right directions, and the front-back, left-right limiting of the limiting plate 6 can limit the sealing plate 41 in the front-back, left-right directions, thereby improving the moving stability of the sealing plate 41.

[0030] Reference Figure 2 and Figure 3 , a temperature sensor 8 is fixedly installed on the right side of the inner wall of the ventilation opening 3, a control box 9 is fixedly installed on the front side of the left side of the control cabinet main body 1, a warning lamp 10 is fixedly installed at the bottom of the support plate 42, and both the warning lamp 10 and the temperature sensor 8 are electrically connected to the control box 9 through wires.

[0031] As a technical optimization scheme of the present utility model, by providing the temperature sensor 8, the control box 9 and the warning lamp 10, the temperature sensor 8 detects the temperature inside the control cabinet main body 1 and converts it into an electrical signal and transmits it to the control box 9. The microprocessor in the control box 9 will receive these signals. At the same time, the control box 9 processes the signals according to the preset temperature threshold. If the detected temperature exceeds the normal range, the control box 9 will issue a corresponding control instruction to drive the warning lamp 10 to turn on, so as to facilitate the user to discover in time.

[0032] Reference Figure 2 , an installation opening 11 is provided at the bottom of the left side of the control cabinet main body 1, a ventilation fan 12 is fixedly installed on the inner wall of the installation opening 11, and the ventilation fan 12 is electrically connected to the control box 9 through a wire.

[0033] As a technical optimization scheme of the present utility model, by providing the installation opening 11 and the ventilation fan 12, the installation opening 11 can fix and limit the ventilation fan 12. Starting the ventilation fan 12 through the control box 9 can make the wind generated by the ventilation fan 12 blow into the interior of the control cabinet main body 1. Since the high temperature generated inside the control cabinet main body 1 will rise to the top of the interior of the control cabinet main body 1, the wind generated by the ventilation fan 12 can blow the heat out through the heat dissipation holes 2 and the ventilation openings 3.

[0034] Reference Figure 1 and Figure 4 , a through groove 13 is provided on the left side of the top of the top plate 51, a protective shell 14 is provided outside the servo motor 52, and the bottom of the protective shell 14 is fixedly connected to the top of the top plate 51.

[0035] As a technical optimization solution of the present utility model, by providing a through groove 13 and a protective shell 14, the through groove 13 facilitates the upward movement of the sealing plate 41 and the limiting plate 6 to the top of the top plate 51, and the protective shell 14 can protect the servo motor 52.

[0036] The working principle and usage process of the present utility model: During use, the temperature sensor 8 detects the temperature inside the control cabinet main body 1 and converts it into an electrical signal and transmits it to the control box 9. The microprocessor in the control box 9 will receive these signals. At the same time, the control box 9 processes the signals according to the preset temperature threshold. If the detected temperature exceeds the normal range, the control box 9 will issue corresponding control instructions to drive the warning light 10 to turn on. After the user observes that the warning light 10 is on, the servo motor 52 is first turned on through the control box 9. By starting the servo motor 52, the output end of the servo motor 52 can drive the lead screw 53 to rotate. The rotation of the lead screw 53 can drive the moving plate 43 to move up and down. The upward movement of the moving plate 43 can drive the sealing plate 41 to move upward. At this time, the sealing plate 41 no longer blocks the ventilation opening 3, improving the heat dissipation effect. Then, by starting the ventilation fan 12 through the control box 9, the wind generated by the ventilation fan 12 can be blown into the interior of the control cabinet main body 1. Since the high temperature generated inside the control cabinet main body 1 will rise to the top of the interior of the control cabinet main body 1, the wind generated by the ventilation fan 12 can blow the heat out from the heat dissipation holes 2 and the ventilation opening 3, thereby improving the heat dissipation efficiency.

[0037] In summary: For this ground source heat pump control cabinet, by providing the ventilation opening 3, the ventilation opening 3 has a better heat dissipation effect than the heat dissipation holes, and can quickly dissipate the heat rising to the top of the interior of the control cabinet main body 1, solving the problem that although the fire extinguishing agent can achieve the fire extinguishing effect, when the fire extinguishing agent extinguishes the fire inside the control cabinet main body, the electronic components inside the control cabinet main body have been damaged, and a large-scale repair or direct scrapping is required inside the control cabinet main body. The main reason for the fire inside the control cabinet main body is excessive internal heat accumulation. Therefore, a heat dissipation structure should be added to the control cabinet main body to avoid the problem of fire caused by excessive internal heat accumulation in the control cabinet main body.
