[0037] One end of the motor 61 is fixed to the inner wall of the signal box 1, and the other end is connected to the threaded rod 63 through a rotating shaft 62; the threaded rod 63 is set on the inner wall of the signal box 1 through a shaft sleeve; the end of the threaded rod 63 away from the output shaft of the motor 61 is fixedly penetrated by a fan 69; the signal box 1 is provided with a heat dissipation port 66 that cooperates with the fan 69.

[0038] The circumferential surface of the threaded rod 63 is connected to a threaded sleeve 64, the top of the threaded sleeve 64 is fixedly connected to a push rod 65, the outside of the heat dissipation port 66 is rotatably connected to a rotating shaft 67, the circumferential surface of the rotating shaft 67 is fixedly connected to a baffle 68, and the side surface of the baffle 68 is located on the displacement trajectory of the push rod 65; the inside of the heat dissipation port 66 is fixedly connected to a torsion spring 610, and the end of the torsion spring 610 away from the inside of the heat dissipation port 66 is fixedly connected to the circumferential surface of the rotating shaft 67; the threaded sleeve 64 moves axially along the threaded rod 63, approaching or moving away from the baffle 68.

[0043] The side surface of the baffle 68 is located on the displacement track of the push rod 65. The purpose of the side surface of the baffle 68 being located on the displacement track of the push rod 65 is to ensure that the push rod 65 can push the baffle 68 to open the heat dissipation port 66 during the movement.

[0044] A specific application of this embodiment is: when the data branch line 4 inside the signal box 1 is connected to various monitoring devices of the dam, the electronic components 2 inside the signal box 1 will generate heat through the use of multiple monitoring devices. In order to prevent the electronic components 2 from being damaged by excessive temperature, the staff starts the motor 61, and the output shaft of the motor 61 rotates counterclockwise. The output shaft of the motor 61 rotates counterclockwise to drive the rotating shaft 62 to rotate counterclockwise. The rotating shaft 62 rotates counterclockwise to drive the threaded rod 63 to rotate counterclockwise. The threaded sleeve 6 fixed to the circumferential surface of the threaded rod 63 is screwed. 4 moves from right to left, the threaded sleeve 64 moves from right to left, driving the push rod 65 to move from right to left. In the process of the push rod 65 moving from right to left, the baffle 68 is pushed. The baffle 68 is pushed and rotates clockwise through the rotating shaft 67, thereby opening the heat dissipation vent 66. At the same time, the fan 69 fixed on the circumference of the threaded rod 63 rotates counterclockwise. The fan 69 rotates counterclockwise to dissipate heat from the inside of the signal box 1 through the heat dissipation vent 66. When the signal box 1 is not working, the baffle 68 is not subjected to force and is reset by the elasticity of the torsion spring 610, thereby closing the heat dissipation vent 66.

[0045] Example 2, reference Figure 2 , explaining this embodiment, which is different from Example 1 in that: a dustproof net 614 is fixedly connected to the interior of the heat dissipation port 66. The function of the dustproof net 614 fixedly connected to the interior of the heat dissipation port 66 is to prevent dust from entering the interior of the signal box 1 when the heat dissipation port 66 is opened.

[0046] Example 3, reference Figures 1-5 , explaining this embodiment, which differs from Example 1 in that: a self-locking mechanism 7 is provided inside the signal box 1, comprising a gear 71 fixedly extending through the rotating shaft 62; a slide groove 72 is provided on the inner wall of the signal box 1, a sliding post 73 being slidably connected to the interior of the slide groove 72; a rack 74 is fixedly connected to the end of the sliding post 73 away from the interior of the slide groove 72; a connecting rod 75 is fixedly connected to the side of the rack 74; a fixing bolt 76 is fixedly connected to the bottom of the connecting rod 75; a fixing plate 77 is fixedly connected to the inner surface of the cover 5; the circumferential surface of the gear 71 and the side of the rack 74 engage with each other; the fixing plate 77 is used to limit the position of the fixing bolt 76. The self-locking mechanism 7 provided inside the signal box 1 is intended to prevent accidents caused by non-staff members from misoperating the signal box 1.

[0047] When the signal box 1 is in use, in order to prevent non-staff from accidentally touching or opening it and causing an accident, the staff closes the cover 5 and starts the motor 61. The output shaft of the motor 61 rotates counterclockwise, and the output shaft of the motor 61 rotates counterclockwise to drive the rotating shaft 62 to rotate counterclockwise. The rotating shaft 62 rotates counterclockwise to drive the gear 71 to rotate counterclockwise. Because the gear 71 and the rack 74 are engaged with each other, the gear 71 rotates counterclockwise to drive the rack 74 to move downward inside the slide groove 72 through the sliding column 73. The rack 74 moves downward and drives the fixing bolt 76 to move downward through the connecting rod 75. The downward movement of the fixing bolt 76 cooperates with the fixing plate 77. The fixing plate 77 blocks the fixing bolt 76 from continuing to move downward for self-locking.

[0048] When the staff starts the heat dissipation work inside the signal box 1, if they accidentally open the cover 5, they may easily touch the working components, causing damage to the components and endangering the staff. In this embodiment, the fixing plate 77 is used to block the fixing bolt 76 moving downward. When the fixing bolt 76 encounters resistance, the motor 61 stops rotating, effectively preventing non-staff from accidentally touching or opening it and causing accidents.

[0049] A compression spring 78 is fixedly connected to the side of the fixing bolt 76, and a cylindrical pin 79 is fixedly connected to the end of the compression spring 78 away from the side of the fixing bolt 76. A self-locking hole 710 is provided on the side of the signal box 1. The cylindrical pin 79 is fixedly connected to the end of the compression spring 78 away from the side of the fixing bolt 76. The function of the self-locking hole 710 is to drive the cylindrical pin 79 to retract and retract through the elasticity of the compression spring 78. The function of the self-locking hole 710 is to self-lock and fix the cover 5 through the cylindrical pin 79 and the self-locking hole 710.

[0050] The circumferential surface of the gear 71 and the side surface of the rack 74 mesh with each other. The role of the circumferential surface of the gear 71 and the side surface of the rack 74 meshing with each other is to ensure that the rotation of the gear 71 can drive the rack 74 to move.

[0051] One specific application of the embodiment is: when the signal box 1 is in use, in order to prevent non-workers from being accidentally touched or opened, and to prevent accidents, the worker starts the motor 61 after closing the cover plate 5, the output shaft of the motor 61 rotates counterclockwise, the output shaft of the motor 61 counterclockwise drives the rotating shaft 62 to rotate counterclockwise, the rotating shaft 62 counterclockwise drives the gear 71 to rotate counterclockwise, because the gear 71 and the rack 74 are engaged with each other, so the gear 71 counterclockwise drives the rack 74 to move downward in the sliding slot 72 through the sliding column 73, the rack 74 moves downward drives the fixed bolt 76 to move downward through the connecting rod 75, the fixed bolt 76 moves downward cooperates with the fixed plate 77, the fixed plate 77 blocks the fixed bolt 76 from continuing to move downward, so that it is fixed at a certain position, and is self-locked, at the same time, the fixed bolt 76 moves downward drives the cylindrical pin 79 to move to the self-locking hole 710 inside through the compression spring 78, and is double self-locked.

[0052] Although the present application has been described in terms of limited embodiments, those skilled in the art will appreciate that other embodiments can be envisaged within the scope of the application as described herein. Furthermore, it should be noted that the language used in the specification has been chosen primarily for readability and instructional purposes and can not have been chosen to convey 5 all technical details. Therefore, numerous modifications and alterations can be made by those skilled in the art without departing from the scope and spirit of the application.
