[0002] Electrical protection boxes, also known as distribution boxes or distribution cabinets, are core components of electrical systems. They are primarily used to distribute electrical energy and protect circuits and equipment from faults such as overloads, short circuits, and leakage current. Their key functions include power distribution, overload protection, short circuit protection, leakage current protection, and over / under voltage protection. They are widely used in industrial, commercial, and residential buildings.

[0039] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0040] In this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0041] Currently, electrical protection boxes typically rely on fixed-size surface vents for air convection cooling, or are supplemented by internal fans for forced cooling. However, these fixed vents cannot dynamically adjust the ventilation volume according to actual cooling needs, presenting a limitation.

[0042] like Figures 1-5 As shown, this utility model embodiment provides an electrical protection box with adjustable ventilation opening, including: a box body 1, a first baffle 2, a second baffle 3, an electric telescopic rod 4, and a pull rope 5, etc.

[0043] The main body 1 of the box is provided with a first ventilation opening 111 and a second ventilation opening 112.

[0044] The first baffle 2 is slidably disposed on the main body 1 of the box and can cover the first vent 111. The first baffle 2 is configured to adjust the opening of the first vent 111.

[0045] The second baffle 3 is slidably disposed on the main body 1 of the box and can cover the second vent 112. The second baffle 3 is configured to adjust the opening of the second vent 112.

[0046] The electric telescopic rod 4 is installed on the main body 1 of the box, and its output end is connected to the second baffle 3. The electric telescopic rod 4 can drive the second baffle 3 to move back and forth. During the reciprocating movement, the second baffle 3 realizes the adjustability of the opening of the second ventilation port 112.

[0047] A pull rope 5 is installed on the main body 1 of the box, with one end connected to the second baffle 3 and the other end connected to the first baffle 2. When the second baffle 3 reciprocates under the drive of the electric telescopic rod 4, the pull rope 5 moves synchronously with the first baffle 2, and the opening degree of the first vent 111 is adjustable during the movement of the first baffle 2.

[0048] Specifically, such as Figures 1-3 As shown, the main body 1 of the box includes a main body 11 and an air duct extension 12.

[0049] The main body 11 has a receiving cavity 110 inside, which is used to accommodate electrical components. A door 6 is rotatably provided on the main body 11. An air duct extension 12 is provided on the main body 11, and has an air duct cavity 120 inside, which can communicate with the receiving cavity 110. The horizontal ends of the air duct extension 12 are open structures.

[0050] like Figure 2 As shown, the first ventilation opening 111 is located on the side wall of the main body 11.

[0051] The first baffle 2 is slidably disposed on the inner side wall of the main body 11, corresponding to the first vent 111. Figure 1 As shown, when the first baffle 2 slides vertically downwards, the first vent 111 closes, as... Figure 2 As shown, when the first baffle 2 slides vertically upward, the first vent 111 opens, and the opening degree of the first vent 111 can be continuously adjusted through the sliding action of the first baffle 2.

[0052] Furthermore, to prevent the first vent 111 from being completely closed, in this embodiment, the lower end of the first baffle 2 (that is, the end near the bottom of the main body 11) is provided with a plurality of first ventilation holes 21. When the first baffle 2 is completely closed (slid down), the first ventilation holes 21 can provide a minimum ventilation channel, thereby preventing the first vent 111 from being completely closed.

[0053] Furthermore, there are two sets of first vents 111, symmetrically arranged on opposite side walls of the main body 11. Correspondingly, there are also two sets of first baffles 2, symmetrically and slidably arranged on opposite inner side walls of the main body 11, each matching the corresponding first vent 111. The two sets of first baffles 2 act independently on their respective first vents 111.

[0054] like Figure 5 As shown, the second ventilation opening 112 is opened on the top wall of the main body 11, specifically including a plurality of second ventilation holes 1121 distributed at intervals.

[0055] like Figures 4-5 As shown, the second baffle 3 is slidably mounted on the inner wall of the air duct extension 12, and has multiple third ventilation holes 31 on it. The positions of the third ventilation holes 31 correspond to the positions of the second ventilation holes 1121. When the second baffle 3 is in its original position, the two holes (second ventilation hole 1121 and third ventilation hole 31) are offset, and the second ventilation opening 112 is closed. When the second baffle 3 slides horizontally to one end, the two holes (second ventilation hole 1121 and third ventilation hole 31) are aligned, and the second ventilation opening 112 is opened. By controlling the sliding of the second baffle 3, the opening degree of the second ventilation opening 112 can be continuously adjusted.

[0056] Furthermore, there are two sets of second vents 112, spaced apart on the top wall of the main body 11. Correspondingly, there are also two sets of second baffles 3, each matching a corresponding second vent 112. Each set of second baffles 3 acts independently on its corresponding second vent 112.

[0057] like Figure 4 As shown, the electric telescopic rod 4 is fixedly installed on the top wall of the main body 11, and its output end is connected to the second baffle 3, which can drive the second baffle 3 to slide.

[0058] Furthermore, the electric telescopic rods 4 are in two sets, each independently driving its corresponding second baffle 3. Each set of electric telescopic rods 4 includes two electric telescopic rods 4 spaced apart.

[0059] Furthermore, there are also two sets of pull ropes 5, which act independently on the corresponding first baffle 2 and second baffle 3.

[0060] In use, when it is necessary to adjust the opening of the first vent 111 and the second vent 112, the electric telescopic rod 4 is activated. The electric telescopic rod 4 extends, driving the second baffle 3 to slide horizontally, while simultaneously driving the first baffle 2 to slide vertically upward via the pull rope 5. As the second baffle 3 slides, its third vent 31 gradually aligns with the second vent 1121. When the two vent arrays are completely aligned, the second vent 112 reaches its maximum opening. As the first baffle 2 slides upward, the opening of the first vent 111 simultaneously increases to its maximum.

[0061] When it is necessary to close the second vent 112 and adjust the opening of the first vent 111 to its minimum value, the electric telescopic rod 4 is activated. The electric telescopic rod 4 retracts, driving the second baffle 3 to slide horizontally in the opposite direction. At the same time, the first baffle 2 slides vertically downward under its own weight. As the second baffle 3 slides, its third vent 31 gradually shifts away from the second vent 1121. When the two vent arrays are completely shifted, the second vent 112 closes. As the first baffle 2 slides downward, the opening of the first vent 111 is simultaneously adjusted to its minimum value.

[0062] Furthermore, in order to increase the downward speed of the first baffle 2, in this embodiment, as... Figure 3 As shown, a tension spring 7 is fixedly installed on the bottom wall of the main body 11, and the extension end of the tension spring 7 is connected to one end of the first baffle 2. When the first baffle 2 slides upward under external force, the tension spring 7 is simultaneously stressed and in a stretched state. When the external force on the first baffle 2 disappears and it slowly slides down under its own weight, the tension spring 7 resets and drives the first baffle 2 to slide down rapidly.

[0063] Furthermore, there are two sets of tension springs 7, each acting independently on its corresponding first baffle 2.

[0064] Furthermore, in order to accelerate air circulation, in this embodiment, as... Figure 3 As shown, a cooling fan 8 is provided on the inner wall of the main body 11, and the cooling fan 8 is opposite to the second vent 112. The cooling fan 8 accelerates the discharge of hot air inside the main body 11 through the second vent 112.

[0065] Furthermore, in order to monitor the internal temperature of the main body 11 in real time, a temperature sensor (not shown in the figure) is also provided inside the main body 11 in this embodiment.

[0066] Specifically, in this embodiment, the temperature sensor is a digital temperature sensor (such as DS18B20) or an analog temperature sensor (such as an NTC thermistor).

[0067] Furthermore, in order to automatically adjust the internal temperature of the main body 11, the electrical protection box in this embodiment also includes a microcontroller (not shown in the figure) for receiving the detection signal from the temperature sensor and generating control commands to automatically adjust the internal temperature of the main body 11.

[0068] Specifically, when the temperature sensor detects that the internal temperature of the main body 11 has reached a preset threshold, it sends a signal to the microcontroller. The microcontroller then outputs instructions to the actuators (electric telescopic rod 4 and cooling fan 8) based on the signal. When cooling is required, the cooling fan 8 is activated, and the electric telescopic rod 4 is simultaneously extended (e.g., opening the first vent 111 and the second vent 112). When heat preservation is required, the cooling fan 8 is turned off, and the electric telescopic rod 4 is simultaneously retracted (e.g., closing the first vent 111 and the second vent 112). By adjusting the opening degree of the first vent 111 and the second vent 112 and the start and stop of the cooling fan 8, the airflow rate is controlled, and dynamic temperature balance is achieved.

[0069] More specifically, the microcontroller in this embodiment is an Arduino or an STM32.

[0070] Furthermore, to prevent rainwater from entering the interior of the main body 11 through the first vent 111 along the outer wall of the main body 11, in this embodiment, a baffle plate 9 is obliquely provided above the first vent 111.

[0071] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
