Description

Technical Field

[0001] The present invention relates to the field of power cabinet dehumidification, and particularly to a power cabinet with a dehumidification function. Background Art

[0002] A power cabinet is an important device for distributing and controlling electric energy in a power system, and is widely used in industrial, commercial and residential buildings. It not only distributes the main power supply to each electrical device, but also has a protection function to ensure the safe and reliable operation of the electrical system.

[0003] Among them, the cabinet body part of the power cabinet is mainly a cabinet shell for protecting the main power supply. At the same time, during the use of the power cabinet, it is also necessary to control the temperature and humidity of its internal use environment to ensure the normal working state of its internal components. After retrieval, the Chinese authorized patent publication number CN105813444A discloses an energy-saving constant-temperature electrical cabinet using natural energy, with a heat insulation layer provided in the shell, and a radiator provided in the shell; a heat dissipation pipeline is buried in the radiator, and the inlet of the heat dissipation pipeline is connected to a water pump and a filter through a valve and a water inlet pipe. The front end of the water inlet pipe extends deep into the underground water source from a groundwater well to form a pipeline circulation, or a heat exchanger buried in deep soil is used to form a closed circulation. During refrigeration, the water vapor filter in the electrical cabinet is used for dehumidification and then an air flow circulation is formed. The above-mentioned prior art uses natural underground heat energy and soil and air heat energy to adjust the temperature and humidity in the cabinet. However, in actual use, on the one hand, directly introducing groundwater into the cabinet will cause the humidity in the cabinet to rise. Although the prior art is provided with a water vapor filter for dehumidification, when the humidity inside the cabinet is relatively high during use, directly introducing the circulating water into the radiator and the cabinet will increase the load on the water vapor filter, affect the service life of the water vapor filter, and affect the normal use of the components in the electrical cabinet. On the other hand, the air inside the power cabinet itself cannot generate self-purification, which will also cause serious dust accumulation inside the cabinet and affect the service life of the components. Based on this, the present invention designs a power cabinet with a dehumidification function. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the prior art, and to propose a power cabinet with a dehumidification function.

[0008] The cabinet body is provided with a space one where a power supply is installed and a space two for ventilation and dehumidification. The space one and the space two are separated by a partition board. A plurality of ventilation holes distributed in a square array are formed in the partition board, and the partition board is fixedly connected to the cabinet door;

[0009] The base table is provided with a heat exchange space, and the heat exchange space includes:

[0010] Underground water pipe one and underground water pipe two.

[0011] A circulation component, which is used to transfer the air in the space one of the cabinet body to the heat exchange space and then introduce it into the space two again;

[0012] The circulation component and the heat exchange component are jointly connected to a driving component and realize the operation of the circulation function and the heat exchange function through the driving component.

[0013] In the above-mentioned power cabinet with a dehumidification function, the heat exchange component includes a connecting disk one and a connecting disk two with different diameters. The diameter of the connecting disk one is smaller than that of the connecting disk two, and the two are respectively fixedly arranged on the tops of the underground water pipe one and the underground water pipe two. The connecting disk one and the connecting disk two are coaxially connected with a rotating pipe one and a rotating pipe two, and the two are respectively rotatably connected in circular grooves formed on the opposite sides of the connecting disk one and the connecting disk two. Both of the two circular grooves are arranged in a "T" shape structure. The underground water pipe one and the underground water pipe two are respectively connected to the two circular grooves through fixed pipes. The rotating pipe one and the rotating pipe two are respectively provided with connecting holes communicating with the corresponding circular grooves. The rotating pipe one and the rotating pipe two are jointly connected with a plurality of inclined pipes. The plurality of inclined pipes form an annular distribution at the connection of the rotating pipe one and the rotating pipe two. Among them, the annular distribution on the rotating pipe one is smaller than the annular distribution on the rotating pipe two. The rotating pipe one is rotatably connected to the connecting disk one through a rotating shaft one, and the rotating pipe two is hermetically connected in the heat exchange space.

[0014] In the above-mentioned power cabinet with a dehumidification function, the circulation component includes a guide vane. The guide vane is rotatably connected to the inner top of the heat exchange space through a rotating shaft two. A connecting pipe one is arranged at the bottom of the cabinet body in the space two, and the connecting pipe one is located directly above the guide vane. The connecting pipe one communicates with the cabinet body and the heat exchange space. A connecting pipe two is embedded in the center of rotation of the rotating pipe two. The connecting pipe two passes through the inner walls of the rotating pipe two and the connecting disk two and is connected to the side of the cabinet body. A one-way valve is hermetically connected in the connecting pipe two. The connecting pipe two is connected to the space one through a plurality of branch pipes.

[0015] In the above-mentioned power cabinet with dehumidification function, the driving assembly includes a driving motor, the driving motor is fixedly connected to the outer side wall of the bottom platform, the output shaft of the driving motor passes through the side wall of the bottom platform and is connected to the first rotating shaft, a first bevel gear is sleeved outside the first rotating pipe, the first bevel gear meshes with a second bevel gear, and the center of rotation of the second bevel gear is connected to the bottom of the second rotating shaft.

[0016] In the above-mentioned power cabinet with dehumidification function, a plurality of the inclined pipes are commonly connected to a filter screen, and the filter screen and the first rotating pipe and the second rotating pipe together form a frustum-shaped structure.

[0017] In the above-mentioned power cabinet with dehumidification function, a discharge port is opened on the side surface of the bottom platform, the discharge port is hermetically connected to a storage box, and the storage box is located directly below the filter screen and the plurality of inclined pipes.

[0018] Compared with the existing technology, the advantages of the present invention are as follows:

[0019] 1. By creating a heat exchange space in the bottom platform, the present invention obtains a space for heat exchange and humidity treatment with the gas inside the cabinet. Utilizing the characteristic that the groundwater temperature is relatively low, the gas with a higher temperature inside the cabinet can be cooled on the one hand, and on the other hand, the water vapor in the air can be condensed when encountering cold, thereby achieving the effect of drying the air inside the cabinet, which can effectively ensure that the environment inside the cabinet meets the normal use requirements of the power cabinet.

[0020] 2. During use, the driving assembly drives the plurality of inclined pipes and the filter screen in the heat exchange assembly to rotate, and a circulation channel is formed between the heat exchange space and the space for storing power through the circulation assembly. In this way, the air inside the cabinet can be circulated and processed. The inclined pipes and the filter screen arranged obliquely form a sealed body, forcing the gas to enter the sealed body and then be discharged from the heat exchange space, which can achieve the self-cleaning effect of the air. The water precipitated from the air is inclined to fall through the frustum structure, quickly separating from the attachment to the sealed body. On the other hand, it can filter the dust in the air and avoid the attachment of dust to the sealed body through the rotating action, which can effectively extend the service life of the circulation assembly and the heat exchange assembly, reduce the probability of maintenance, and the attached water and dust can be separated into the storage box through the rotating action for convenient centralized treatment.

Specific implementation mode

[0028] Refer to Figures 1-6 , a power cabinet with dehumidification function, including a cabinet body 1, the cabinet body 1 is provided with a space one 101 for installing a power supply and a space two 102 for ventilation and dehumidification. The space one 101 and the space two 102 are separated by a partition board 103. A plurality of ventilation holes 105 distributed in a square array are opened in the partition board 103. The air in the space one 101 is transferred to the space two 102 through the ventilation holes 105. The partition board 103 is fixedly connected with the cabinet door 104, so that the partition board 103 and the cabinet door 104 can rotate simultaneously. A discharge port is opened on the side of the base table 2, and a storage box 8 is hermetically connected to the discharge port. The accumulated water and dust on the base table 2 can be collected and discharged through the storage box 8. The self-cleaning efficiency of the heat exchange space 21 can be improved by installing a negative pressure fan on the storage box 8;

[0029] A bottom platform 2 is fixedly arranged on the lower end surface of the cabinet body 1, and the bottom of the bottom platform 2 is fixedly arranged on the ground. A heat exchange space 21 is opened in the bottom platform 2. The heat exchange space 21 includes a first underground water pipe 31 and a second underground water pipe 32. The first underground water pipe 31 and the second underground water pipe 32 respectively introduce tap water or groundwater into a heat exchange component 4 in the heat exchange space 21. At this time, the groundwater or tap water is always in a flowing state. Therefore, the heat exchange space 21 will always have a heat exchange part with a lower temperature. The first underground water pipe 31 and the second underground water pipe 32 are vertically inserted into the heat exchange space 21 and are located on both sides of the heat exchange space 21. The heat exchange component 4 includes a first connecting disk 41 and a second connecting disk 42 with different diameters. The diameter of the first connecting disk 41 is smaller than that of the second connecting disk 42, and the two are respectively fixedly arranged on the tops of the first underground water pipe 31 and the second underground water pipe 32. The first connecting disk 41 and the second connecting disk 42 are coaxially connected with a first rotating pipe 43 and a second rotating pipe 44, and the two are respectively rotatably connected in circular grooves 47 cooperatively opened on the opposite sides of the first connecting disk 41 and the second connecting disk 42. Both of the two circular grooves 47 are arranged in a "T" shape. The first underground water pipe 31 and the second underground water pipe 32 are respectively connected to the two circular grooves 47 through fixing pipes 48. The first rotating pipe 43 and the second rotating pipe 44 are respectively provided with connecting holes 49 communicating with the corresponding circular grooves 47. The first rotating pipe 43 and the second rotating pipe 44 are commonly connected with a plurality of inclined pipes 45. The plurality of inclined pipes 45 are annularly distributed at the connection part of the first rotating pipe 43 and the second rotating pipe 44. Among them, the annular distribution on the first rotating pipe 43 is smaller than the annular distribution on the second rotating pipe 44. The plurality of inclined pipes 45 are commonly connected with a filter screen 7. The filter screen 7 and the first rotating pipe 43 and the second rotating pipe 44 together form a frustum-shaped structure. The second rotating pipe 44 is hermetically connected in the heat exchange space 21. In this way, after the groundwater or tap water enters the circular groove 47 through the fixing pipe 48, it can enter the rotating pipe through the connecting hole 49, and then be connected to the inclined pipes 45 through the first rotating pipe 43 and the second rotating pipe 44, so that the inclined pipes 45 are in a state with a lower temperature under the action of heat exchange. In this way, the air entering the heat exchange space 21 through the first connecting pipe 53 will fully contact and exchange heat with the sealed body composed of the plurality of inclined pipes 45 and the filter screen 7, so that the air with a higher temperature and higher humidity condenses and precipitates moisture, realizing the dual functions of dehumidification and cooling.

[0030] A circulation component 5 is also arranged in the heat exchange space 21. The circulation component 5 is used to transfer the air in the space 101 of the cabinet body 1 to the heat exchange space 21 and then pass it into the space 102 again. The circulation component 5 includes a guide vane 51. The guide vane 51 is rotatably connected to the inner top of the heat exchange space 21 through a rotating shaft two 52. A connecting pipe one 53 is arranged at the bottom of the cabinet body 1 in the space 102. The connecting pipe one 53 is located directly above the guide vane 51. The connecting pipe one 53 communicates the cabinet body 1 and the heat exchange space 21. A connecting pipe two 54 is embedded in the rotation center of the rotating pipe two 44. The connecting pipe two 54 passes through the inner walls of the rotating pipe two 44 and the connecting disk two 42 and is connected to the side surface of the space 101. A one-way valve is hermetically connected in the connecting pipe two 54;

[0031] The circulation component 5 and the heat exchange component 4 are jointly connected with a driving component 6 and the operation of the circulation function and the heat exchange function is realized through the driving component 6. The driving component 6 includes a driving motor 61. The driving motor 61 is fixedly connected to the outer side wall of the base 2. The output shaft of the driving motor 61 passes through the side wall of the base 2 and is connected to the rotating shaft one 46. A bevel gear one 62 is sleeved on the outer side of the rotating pipe one 43. The bevel gear one 62 meshes with a bevel gear two 63. The rotation center of the bevel gear two 63 is connected to the bottom of the rotating shaft two 52.

[0032] When the present invention is in use, the power supply is normally stored through the space 101. And on the side close to the cabinet door 104, the partition 103 divides the space on the side of the cabinet body 1 away from the power supply into the space 102. And through a plurality of ventilation holes 105 on the partition 103, the space 101 and the space 102 are conducted, so that the air in the space 101 can enter the space 102 and enter the heat exchange space 21 through the connecting pipe one 53 at the bottom of the space 102. And when the air enters the heat exchange space 21, since there is only one air outlet part, namely the connecting pipe two 54, in this space, the air will pass through the sealing body composed of a plurality of inclined pipes 45 and the filter screen 7 and enter its interior. In this process, sufficient heat exchange is generated with the filter screen 7 and a plurality of inclined pipes 45, and the filtering work is realized, so that the relatively hot air in the space 101 is condensed into dry air and cooled. In this way, the gas re-output to the space 101 through the connecting pipe two 54 and a plurality of branch pipes 55 meets the working requirements of the power supply. And the water separated from the hot air and the dust carried by itself will adhere to the outer surface of the sealing body composed of a plurality of inclined pipes 45 and the filter screen 7. Since its shape is set as a frustum of a cone and it is always in a rotating state under the drive of the connecting disk one 41 and the connecting disk two 42 on both sides and the driving component 6, the water and dust will fall off the surface. A discharge port and a storage box 8 are arranged at the bottom of the heat exchange space 21 of the present invention. The storage box 8 is slidably connected to the discharge port by a track structure. Therefore, the collected dust and accumulated water can be centrally processed through the storage box 8.

[0033] As is known by common technical knowledge, the present invention can be implemented by other embodiments that do not depart from its spiritual essence or essential features. Therefore, the above-disclosed embodiments are illustrative in all aspects and not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
