Description

[0002] With the increasing environmental pollution caused by fossil fuels, renewable clean energy sources such as solar energy and wind power are attracting significant attention. Photovoltaics is a key area for the effective utilization of solar energy, and global photovoltaic usage is growing rapidly. Against this backdrop, the solar photovoltaic industry has become an essential component of my country's energy strategy. Since photovoltaic power generation utilizes sunlight to generate electricity, environmental monitoring is crucial. Data acquisition boxes, along with environmental monitoring equipment, are installed outdoors in the open air. To prevent rain and dust from affecting the internal components of photovoltaic data acquisition boxes, existing data acquisition boxes are generally sealed. While the power generation efficiency of photovoltaic power stations is greatly improved during the sunny summer months, the high surface temperature of photovoltaic data acquisition boxes under high-intensity sunlight prevents them from effectively conducting or dissipating the heat generated by their internal electronic components. This leads to excessive temperatures, which can damage the electronic components within the data acquisition box. Therefore, a photovoltaic data acquisition box is proposed. Utility Model Content

[0003] The purpose of the utility model is to provide a photovoltaic data acquisition box to solve the technical problem that when the photovoltaic data acquisition box is exposed to high-intensity sunlight, the surface temperature of the photovoltaic data acquisition box is high, making it impossible for the photovoltaic data acquisition box to effectively conduct or dissipate the heat generated by its internal electronic components during operation, resulting in excessive temperature and thus damaging the electronic components inside the data acquisition box.

[0004] To achieve this purpose, the present invention adopts the following technical solutions:

[0023] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] In the description of the present invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description. They are not intended to indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally located component.

[0025] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0026] Reference Figures 1 to 3 The present invention provides a photovoltaic data acquisition box, comprising an outer box body 10, an inner box body 20, and a heat dissipation assembly 30. The upper and lower end surfaces of the outer box body 10 are provided with a plurality of heat dissipation holes 11. The inner box body 20 is disposed within the inner cavity of the outer box body 10. The inner cavity of the inner box body 20 is provided with a data acquisition assembly. The inner box body 20 is a heat dissipation aluminum shell. The outer wall of the inner box body 20 and the inner wall of the outer box body 10 together form a heat dissipation space. A temperature sensor (not shown) is provided within the heat dissipation space. Optionally, the outer box body 10 is made of a material with good thermal insulation properties, such as ceramic fiber material, or the outer surface of the outer box body 10 is coated with a thermal insulation layer. When the outer surface of the outer box body 10 is exposed to sunlight, it can effectively isolate external heat from entering the inner cavity of the outer box body 10. The photovoltaic data acquisition box provided by the present invention, when installed outdoors, provides a relatively low-temperature space (i.e., the inner cavity of the outer housing) through the outer housing 10. The inner housing 20, which houses the data acquisition components, is placed within this space. The inner housing 20 is made of aluminum with a high heat dissipation coefficient. Heat generated by the data acquisition components during operation is quickly transferred to the inner housing 20. Simply lowering the temperature within this space lowers the temperature of the data acquisition components, thereby improving the heat dissipation efficiency of the photovoltaic data acquisition box. When heat from the data acquisition components is transferred to the inner housing 20, raising the temperature of the heat dissipation space, the heat is discharged through the heat dissipation holes 11, thereby improving the heat dissipation efficiency of the photovoltaic data acquisition box.

[0027] Reference Figure 2, a second support column 13 is provided on the inner wall of the outer box body 10, and the inner box body 20 is provided on the second support column 13. Optionally, a sun visor 35 is provided in the heat dissipation space. The second support column 13 passes through the sun visor 35, so that the sun visor 35 is fixedly provided on the second support column 13. There are two sun visors 35, and they are respectively close to the upper end face and the lower end face of the outer box body 10. The sun visor 35 is parallel to the upper end face of the outer box body 10. The inner box body 20 is provided between the two sun visors 35. When sunlight shines into the inner cavity of the outer box body 10 through the heat dissipation hole 11, the sun visor 35 prevents sunlight from irradiating the inner box body 20, thereby preventing the inner box body 20 from being heated by sunlight.

[0028] The heat dissipation assembly 30 is disposed within the heat dissipation space and includes a fan 33. When sunlight is strong and the airflow generated by natural wind and the heat dissipation holes 11 is insufficient to provide adequate heat dissipation, that is, when the temperature sensor detects that the temperature within the heat dissipation space exceeds a preset temperature, the fan 33 is activated to increase the airflow within the heat dissipation space and accelerate the removal of heat from the heat dissipation space.

[0029] The heat dissipation assembly 30 further includes a water tank 31 and a spray head 32 disposed on one side of the water tank 31. The fan 33 is disposed next to the spray head 32. Specifically, a first support column 12 is further disposed on the inner wall of the outer box body 10, and the water tank 31 is disposed on the first support column 12. A semicircular air duct 34 surrounding three sides is disposed on the inner side surface of the outer box body 10, and the air outlet end of the fan 33 is disposed at one end of the air duct 34, that is, the air outlet of the fan 33 is aligned with one end of the air duct 34. When the fan 33 is working, the airflow generated by the fan 33 can partially surround the air duct 34 to form an airflow surrounding the heat dissipation space. When the sunlight intensity is extremely high and the heat dissipation effect cannot be achieved by increasing the airflow intensity, water mist can be sprayed through the spray head 32, and the fan 33 can be started at the same time. The fan 33 forms the water mist into a water mist airflow surrounding the heat dissipation space through the air duct 34. The water mist can absorb heat by evaporation and then be discharged through the heat dissipation holes 11, thereby discharging the heat from the heat dissipation space and improving the heat dissipation effect of the inner box body 20.

[0030] Optionally, the water tank 31 is located on a side of the heat dissipation space away from the air duct 34, that is, the water tank 31 is located close to the side of the outer box 10 where the air duct 34 is not present. The air duct 34 surrounds three sides of the outer box 10, leaving one side for the water tank 31 to be installed, thereby reducing the volume of the photovoltaic data acquisition box. Secondly, when the water mist airflow surrounding the heat dissipation space is on the side without the air duct 34, it is more easily discharged through the heat dissipation holes 11.

[0031] Optionally, the heat dissipation assembly 30 further includes a plurality of heat sinks 36, one end of each heat sink 36 extending into the inner box body 20 and the other end extending into the water tank 31. Heat within the inner box body 20 is transferred to the heat sink 36, which then transfers the heat to the water tank 31, where it is cooled by the water in the water tank 31.

[0032] Reference Figure 3 The inner box body 20 includes a lower box 21 and an upper box 22, and the inner box body 20 is detachably connected to the second support column 13, that is, the inner box body 20 can be separated from the outer box body 10 and used independently.

[0033] Specifically, the lower box 21 and the upper box 22 are bonded together with sealant to form a sealed inner cavity, within which a data acquisition component (not shown) is housed. Specifically, the inner sidewalls of the lower box 21 are provided with lower protrusions (not shown) surrounding the opening, while the outer sidewalls of the upper box 22 are provided with upper protrusions (not shown) surrounding the opening. The lower protrusions correspond to the upper protrusions, facilitating precise positioning of the upper and lower boxes 22 and 21 when they are closed. The upper end surface of the inner box 20 is provided with a mounting hole, within which LED indicators 23 are located. These indicators 23 include a power indicator, a device indicator, a network indicator, and a cloud indicator, allowing the user to monitor their operating status. Sealant is filled between the LED indicators 23 and the walls of the mounting hole to prevent external dust and moisture from entering the inner cavity. A waterproof data port 24 is provided on the side of the inner box 20. This port includes a wireless antenna port, an RS-485 communication port, and a power port. The bottom surface of the inner box body 20 is provided with a wall hanging hole (not shown) for hanging the inner box body 20 on a wall when used alone.

[0034] It should be noted that a mounting groove (not shown) is provided on the lower end surface of the inner box body 20 for mounting the inner box body 20 on the second support column 13 .

[0035] The utility model discloses a photovoltaic data acquisition box, specifically, an embodiment of the present invention as follows: when the sunlight intensity is low, the inner box body 20, which is equipped with the data acquisition component, is enclosed in the inner cavity of the outer box body 10, thereby preventing sunlight from irradiating the inner box body 20. At the same time, the air in the heat dissipation space is connected to the outside air through the heat dissipation holes 11, which can form airflow in the heat dissipation space, accelerate the dissipation of heat in the heat dissipation space, and thus improve the heat dissipation effect of the photovoltaic data acquisition box; when the sunlight intensity increases, the temperature sensor detects that the temperature in the heat dissipation space is high, that is, when the air flow intensity of the air itself cannot meet the heat dissipation effect, the fan 33 is activated to increase the airflow intensity to enhance the heat dissipation effect; when the sunlight intensity is extremely high and the heat dissipation effect cannot be achieved by increasing the air flow intensity, water mist is sprayed through the spray head 32. At the same time, the fan 33 forms a water mist airflow surrounding the heat dissipation space through the air duct 34. The water mist can absorb heat through evaporation and is then discharged through the heat dissipation holes 11, thereby dissipating the heat in the heat dissipation space and improving the heat dissipation effect of the inner box body 20. The photovoltaic data acquisition box provided by the present invention can adjust the heat dissipation component 30 to dissipate heat to the inner box body 20 according to the intensity of sunlight, so as to cope with different intensities of sunlight and avoid damage to the electronic components inside the data acquisition box due to excessive temperature of the inner box body 20.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
