Description

Technical Field

[0001] The utility model relates to the technical field of temperature and humidity control systems for distribution cabinets, and particularly relates to an intelligent temperature and humidity control device for distribution cabinets. Background Art

[0002] In the power system, when the distribution cabinet operates in summer, the heat generation is relatively large. When it operates in winter, the ambient temperature is too low. These adverse temperature and humidity environments will affect the accuracy of detection instruments and sensors, bringing huge negative impacts to power distribution, and even having an adverse effect on the entire power grid. Traditional distribution cabinets only use ventilation holes for ventilation, and the balance effect of the temperature and humidity environment inside the distribution cabinet is poor, and it is still extremely easy to affect the accuracy of detection instruments and sensors.

[0003] Chinese Patent with the application number CN202123328942.7 discloses an intelligent temperature and humidity control device for a distribution cabinet. The device includes a temperature sensor, a humidity sensor, a cooling fan, a heater, a blower, and a controller. The temperature sensor, the humidity sensor, the cooling fan, the heater, and the blower are all connected to the controller. The temperature sensor is used to detect the temperature data inside the distribution cabinet, and the humidity sensor is used to detect the humidity data inside the distribution cabinet. The controller is used to control the cooling fan, the heater, and the blower to work according to the detected temperature data and humidity data. However, the designed cooling fan, heater, and blower of this intelligent temperature and humidity control device for the distribution cabinet cannot quickly change the temperature and humidity inside the distribution cabinet, so that the distribution cabinet cannot quickly and stably work in a suitable temperature and humidity environment, which has a certain impact on the stable operation of the distribution cabinet. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the problems of the prior art and provide an intelligent temperature and humidity control device for a distribution cabinet.

[0005] To achieve the above purpose, the utility model adopts the following scheme:

[0006] An intelligent temperature and humidity control device for a distribution cabinet is applied to the distribution cabinet. An air outlet is opened at the top of the distribution cabinet. The intelligent temperature and humidity control device for the distribution cabinet includes a temperature and humidity sensor arranged inside the distribution cabinet and a control module arranged outside the distribution cabinet. It further includes:

[0007] An air ventilation grid tube group, which is installed inside the back of the distribution cabinet to ventilate towards the front of the distribution cabinet;

[0008] A heating coil group, which is installed inside the rear end of the distribution cabinet and is located in front of the air ventilation grid tube group;

[0009] A cooling fan is installed at the bottom end of the power distribution cabinet and blows air towards the air outlet.

[0010] The control module is electrically connected to the temperature and humidity sensor, the heating coil group, and the cooling fan respectively.

[0011] Further, the ventilation grid pipe group includes horizontal pipes and vertical pipes; a plurality of the horizontal pipes are arranged at intervals from top to bottom relative to the power distribution cabinet; a plurality of the vertical pipes are arranged at intervals from left to right relative to the power distribution cabinet, and a plurality of the horizontal pipes intersect horizontally and vertically to form the ventilation grid pipe group; each intersection of each horizontal pipe and a plurality of the vertical pipes has an air outlet for ventilating towards the front of the power distribution cabinet.

[0012] Further, an air outlet pipe extending along the front of the power distribution cabinet is connected to the air outlet.

[0013] Further, the ventilation grid pipe group is made of stainless steel.

[0014] Further, the unfolded area of the ventilation grid pipe group is larger than the unfolded area of the heating coil group.

[0015] Further, the heating coil group is bent to form a plurality of U-shaped circuits connected end to end.

[0016] Further, a dust-proof net is installed at the air outlet.

[0019] Compared with the existing technology, the utility model has the following advantages:

[0020] In this utility model, a temperature and humidity sensor, a control module, a ventilation grid pipe group, a heating coil group and a cooling fan are installed on a power distribution cabinet. Under the control of the control module, when the temperature and humidity sensor detects that the temperature inside the power distribution cabinet is too high or both the temperature and humidity are too high, the ventilation grid pipe group and the cooling fan work together. The ventilation grid pipe group introduces a set amount of air into the power distribution cabinet, evenly blowing towards all corners of the power distribution cabinet, and then the cooling fan quickly replaces the gas inside the power distribution cabinet, enabling the temperature and humidity inside the power distribution cabinet to quickly balance, achieving the effect of rapid cooling and preventing the internal temperature and humidity of the power distribution cabinet from being too high. When the temperature and humidity sensor detects that the temperature inside the power distribution cabinet is too low or both the temperature and humidity are too low, the ventilation grid pipe group and the heating coil group work together. The heating coil group heats up to generate heat, and the ventilation grid pipe group can introduce a set amount of air or humidified air, quickly dispersing the heat and air throughout the power distribution cabinet, effectively increasing the temperature and humidity inside the power distribution cabinet. By designing this intelligent temperature and humidity control device for the power distribution cabinet in this way, the ventilation area of the power distribution cabinet is increased, the gas environment inside the power distribution cabinet can be quickly changed, and the balance of the temperature and humidity inside the power distribution cabinet can be adjusted more quickly, enabling the power distribution cabinet to always operate in a suitable temperature and humidity environment, thereby ensuring the efficient and reliable operation of the power distribution cabinet.

The control module 3 is electrically connected to the temperature and humidity sensor 2, the heating coil group 5, and the cooling fan 6 respectively.

[0029] The intelligent temperature and humidity control device for the distribution cabinet 1 installs the temperature and humidity sensor 2, the control module 3, the air vent grid pipe group 4, the heating coil group 5, and the cooling fan 6 on the distribution cabinet 1. Under the control of the control module 3, when the temperature and humidity sensor 2 detects that the temperature inside the distribution cabinet 1 is too high or both the temperature and humidity are too high, the air vent grid pipe group 4 and the cooling fan 6 work together. The air vent grid pipe group 4 introduces a set amount of air into the distribution cabinet 1, evenly blowing towards all corners of the distribution cabinet 1, and then using the cooling fan 6 to quickly replace the gas inside the distribution cabinet 1, so that the temperature and humidity inside the distribution cabinet 1 are quickly balanced, achieving the effect of rapid cooling and preventing the internal temperature and humidity of the distribution cabinet 1 from being too high; when the temperature and humidity sensor 2 detects that the temperature inside the distribution cabinet 1 is too low or both the temperature and humidity are too low, the air vent grid pipe group 4 and the heating coil group 5 work together. The heating coil group 5 heats up and generates heat. The air vent grid pipe group 4 can introduce a set amount of air or humidified air, quickly dispersing the heat and air throughout the distribution cabinet 1, effectively increasing the temperature and humidity inside the distribution cabinet 1. By designing the intelligent temperature and humidity control device for the distribution cabinet 1 in this way, the ventilation area of the distribution cabinet 1 is increased, the gas environment inside the distribution cabinet 1 can be quickly changed, and the balance of the temperature and humidity inside the distribution cabinet 1 can be adjusted more quickly, enabling the distribution cabinet 1 to always work in a suitable temperature and humidity environment, thereby ensuring the efficient and reliable operation of the distribution cabinet 1.

[0030] Preferably, the ventilation grid pipe group 4 includes transverse pipes 41 and vertical pipes 42; a plurality of the transverse pipes 41 are arranged at intervals from top to bottom relative to the power distribution cabinet 1; a plurality of the vertical pipes 42 are arranged at intervals from left to right relative to the power distribution cabinet 1, and a plurality of the transverse pipes 41 intersect horizontally and vertically to form the ventilation grid pipe group 4; each intersection of each transverse pipe 41 and a plurality of the vertical pipes 42 has an air outlet for ventilating forward towards the power distribution cabinet 1. By providing the transverse pipes 41 and the vertical pipes 42, the plurality of transverse pipes 41 and vertical pipes 42 are regularly arranged on the back surface of the power distribution cabinet 1, increasing the ventilation area of the power distribution cabinet 1, which can quickly change the gas environment inside the power distribution cabinet 1, accelerate the adjustment of the temperature and humidity balance inside the power distribution cabinet 1, enable the power distribution cabinet 1 to always operate in a suitable temperature and humidity environment, and thus ensure the efficient and reliable operation of the power distribution cabinet 1.

[0034] In this embodiment, the heating coil group 5 is bent to form a number of U-shaped circuits connected end to end. Designing the heating coil group 5 in this way can better disperse the heat at various angles inside the power distribution cabinet 1 and change the temperature environment inside the power distribution cabinet 1.

[0036] It should be noted that the temperature and humidity sensor 2, the control module 3, the wireless communication module 8, the cloud platform 9, the user terminal 10, and the alarm module 20 are all common standard components or components known to those skilled in the art.
