[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-2 In the embodiment of the utility model, an electromechanical power supply and distribution device comprises a bottom frame 1 and a distribution cabinet 2, the bottom frame 1 is mounted with the distribution cabinet 2, the bottom surface of the distribution cabinet 2 is provided with an air suction port 3, a suction fan 4 is installed in the air suction port 3, both sides of the bottom frame 1 are provided with air inlets 5, a dustproof net 6 is installed in the air inlet 5, a baffle 7 is arranged inside the bottom frame 1 facing the air inlet 5, a hinge 8 is installed on the upper part of the baffle 7, and the baffle 7 is hinged to the bottom frame 1 through the hinge 8;

[0020] The inner side surface of the bottom frame 1 is an inclined surface. The inclined design allows the baffle 7 to be close to the air inlet 5 in a natural state, thereby achieving sealing of the air inlet 5. The baffle 7 is an acrylic plate. The use of acrylic material can make the baffle 7 lighter, so that the baffle 7 can be more easily sucked inward by the negative pressure in the bottom frame 1.

[0021] See also Figure 1 and Figure 3An air outlet 13 is provided on the top of the distribution cabinet 2, and a bidirectional ball screw 9 is arranged on the top of the distribution cabinet 2. The bidirectional ball screw 9 is rotatably connected to the distribution cabinet 2, and one end of the bidirectional ball screw 9 is directly connected to the output shaft of the motor 10 installed on the outer wall of the distribution cabinet 2. Two screw nuts 11 are installed on the bidirectional ball screw 9, and a combined sealing plate 12 is installed on the two screw nuts 11. The combined sealing plate 12 includes an upper plate body 1201, a lower plate body 1202 and a connecting plate 1203. The upper plate body 1201 and the lower plate body 1202 are connected by the connecting plate 1203. The top plate part of the distribution cabinet 2 is located between the upper plate body 1201 and the lower plate body 1202. The upper plate body 1201 and the lower plate body 1202 clamp the top plate of the distribution cabinet 2 in the middle, which can prevent the combined sealing plate 12 from deflecting during movement;

[0022] The side of the combined sealing plate 12 is "C"-shaped, and such a design can make the combined sealing plate 12 and the air outlet 13 better matched, so that the sealing effect of the air outlet 13 is better;

[0023] The two combined sealing plates 12 are arranged symmetrically. The symmetry allows the insertion openings of the two combined sealing plates 12 to be aligned with the two sides of the air outlet 13, so as to facilitate the lateral movement of the combined sealing plates 12 at the position of the air outlet 13.

[0024] See also Figure 1 A temperature sensor 14 is installed in the distribution cabinet 2. The temperature sensor 14 is electrically connected to a temperature controller installed on the outer wall of the distribution cabinet 2. The temperature controller is electrically connected to the suction fan 4 and the motor 10 respectively. The temperature sensor 14 and the temperature controller are both well-known structures in the art. The opening and closing of the temperature control device is also a well-known existing technology. Therefore, the utility model will not be described in detail.

[0025] The working principle of the utility model is:

[0026] During use, when the temperature sensor 14 detects that the temperature inside the distribution cabinet 2 is higher than the preset maximum temperature threshold, the suction fan 4 and the motor 10 are started through the external temperature controller, and the suction fan 4 draws the gas in the bottom frame 1 into the distribution cabinet 2. The baffle 7 opens inward under the action of negative pressure, so that external air can enter the distribution cabinet 2. At the same time, the motor 10 drives the two-way ball screw 9 to rotate, and the two-way ball screw 9 drives the two combined sealing plates 12 to move to both sides to open the air outlet 13, so that the air inside and outside the distribution cabinet 2 can circulate quickly to bring out the heat. When the temperature sensor 14 detects that the temperature inside the distribution cabinet 2 is lower than the preset minimum temperature threshold, the suction fan 4 and the motor 10 are turned off. At this time, the baffle 7 will automatically cover the air inlet 5, and the two combined sealing plates 12 will move back to close the air outlet 13, thereby sealing the distribution cabinet 2.

[0027] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
