[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0023] like Figures 1 to 3 As shown, an electric window opener fire linkage control box includes a control box 1. The two opposite side walls of the control box 1 are provided with a plurality of heat dissipation holes 5 which are evenly distributed and installed. A fixed plate 8 is fixedly installed in the inner cavity of the control box 1. A movable plate 7 is arranged above the fixed plate 8. Five movable rods 6 are fixedly installed above the movable plate 7. The five movable rods 6 respectively pass through the top of the control box 1, and a top collecting plate 3 is fixedly installed at one end of the five movable rods 6 away from the control box 1. When firefighters are in the process of extinguishing a fire, the fire-fighting water will first fall into the top collecting plate 3 arranged above the control box 1. After collecting the water, the top collecting plate 3 will be able to generate weight, so that the top collecting plate 3 can be pressed down, and with the assistance of the five moving rods 6 fixedly installed at the bottom of the top collecting plate 3, the moving plate 7 fixedly installed at the other end can be driven to move, so that the moving baffles 13 fixedly installed on the two side walls of the bottom of the moving plate 7 can move down through the rectangular notches 12 opened on the fixed plate 8 to block the heat dissipation holes 5 on both sides of the control box 1. Therefore, it can avoid to a certain extent the situation that when the firefighters spray the control box 1 from the side during the fire-fighting process, the water will enter the control box 1 from the heat dissipation holes 5 opened on the side walls of the control box 1. Therefore, it can avoid to a certain extent the situation that the internal components or circuits of the control box 1 are damaged.

[0024] The two opposite side walls of the moving plate 7 are provided with sliding mechanisms, which include two slide grooves 9 and two sliders 10. The two slide grooves 9 are respectively provided on the two opposite side walls of the control box 1, and the two slide grooves 9 are symmetrical to each other. The inner cavities of the two slide grooves 9 are both slidably installed with sliders 10, and the two sliders 10 are symmetrical to each other. In this arrangement, it is ensured that when the top collecting plate 3 collects water, it will be able to generate weight, so that the top collecting plate 3 can be pressed down, and with the assistance of the five moving rods 6 fixedly installed at the bottom of the top collecting plate 3, the moving plate 7 fixedly installed at the other end can be driven to move downward with the assistance of the slide grooves 9 and sliders 10 in the sliding mechanism.

[0025] The moving plate 7 is fixedly installed above the two sliders 10, and the reset springs 11 are fixedly installed around the bottom of the moving plate 7, and the other ends of the four reset springs 11 are fixedly connected to the fixed plate 8. In this configuration, when the moving plate 7 moves downward, the reset springs 11 at the bottom can be squeezed to deform the reset springs 11, and the moving baffles 13 fixedly installed on the two side walls of the bottom of the moving plate 7 can move downward through the rectangular notches 12 opened on the fixed plate 8 to block the heat dissipation holes 5 on both sides of the control box 1. At the same time, when the water on the top collecting plate 3 is discharged, the moving plate 7 can be reset with the help of the reset springs 11.

[0026] Rectangular notches 12 are provided on both sides of the fixed plate 8 near the heat dissipation holes 5, and the rectangular notches 12 are symmetrical to each other. The inner cavities of the two rectangular notches 12 are provided with movable baffles 13, and the upper ends of the two movable baffles 13 are respectively fixedly connected to the bottom of the movable plate 7. In this configuration, when the movable plate 7 moves downward, the movable baffles 13 fixedly installed on the two side walls of the bottom of the movable plate 7 can move downward through the rectangular notches 12 provided on the fixed plate 8 to block the heat dissipation holes 5 on both sides of the control box 1. Therefore, it can avoid to a certain extent the situation that when the firefighters spray the control box 1 from the side during the fire fighting, the water will enter the control box 1 from the heat dissipation holes 5 provided on the side walls of the control box 1. Therefore, it can avoid to a certain extent the situation that the internal components or circuits of the control box 1 are damaged.

[0027] The top collecting plate 3 is concave, and a water outlet 4 is provided on one side wall of the top collecting plate 3. A piston is movably provided in the inner cavity of the water outlet 4. In this arrangement, it is ensured that the water in the top collecting plate 3 can be discharged from the water outlet 4 when the piston is pulled out.

[0028] A circular mounting plate 2 is fixedly mounted at the bottom of the top collecting plate 3. The circular mounting plate 2 is larger than the control box 1 and is a light plate. In this arrangement, the circular mounting plate 2 is ensured to protect the outside of the control box 1, and the possibility of water entering the control box 1 is reduced to a certain extent.

[0029] The implementation principle of the fire linkage control box of an electric window opener of this embodiment is as follows: first, when a fire occurs, the control box 1 transmits a signal, and the firefighting work is ready to be carried out. When the firefighters are extinguishing the fire, the fire-fighting water will first fall into the top collecting plate 3 arranged above the control box 1. After collecting the water, the top collecting plate 3 will be able to generate weight, so that the top collecting plate 3 can be pressed down. With the assistance of the five moving rods 6 fixedly installed at the bottom of the top collecting plate 3, the moving plate 7 fixedly installed at the other end can be driven to move downward with the assistance of the slide groove 9 and the slider 10 in the sliding mechanism. When the moving rod 6 is assisted by the five moving rods 6 fixedly installed at the bottom of the top collecting plate 3, the moving plate 7 fixedly installed at the other end can be driven to move downward with the assistance of the slide groove 9 and the slider 10 in the sliding mechanism. During the downward movement of the movable plate 7, the reset spring 11 at the bottom can be squeezed to deform the reset spring 11, and the movable baffles 13 fixedly installed on the two side walls of the bottom of the movable plate 7 can move downward through the rectangular slots 12 opened on the fixed plate 8 to block the heat dissipation holes 5 on both sides of the control box 1. Therefore, it can avoid to a certain extent the situation that when the firefighters spray the control box 1 from the side during the fire extinguishing process, water will enter the control box 1 through the heat dissipation holes 5 opened on the side walls of the control box 1. Therefore, it can avoid to a certain extent the situation that the internal components or circuits of the control box 1 are damaged.
