[0017] The utility model will be specifically introduced below in combination with the drawings and specific embodiments.
[0018] Embodiment: a computer interlocking comprehensive cabinet for railway signal control, like Figures 1-2As shown, including control cabinet 1, rain sensor 2, motor 3, bidirectional screw rod 4, waterproof plate 5, mounting frame 6 and dust screen 7, the top of the control cabinet 1 is fixedly connected with the rain sensor 2 for sensing rain to drive the equipment, the control cabinet 1 is symmetrically installed with the motor 3 on the top, the control cabinet 1 is provided with a controller, the rain sensor 2 and the motor 3 are electrically connected with the controller, the output shaft of the motor 3 is fixedly connected with the bidirectional screw rod 4, the bidirectional screw rod 4 is rotatably connected with the control cabinet 1, two waterproof plates 5 are threadedly connected on each bidirectional screw rod 4, the waterproof plates 5 are slidably connected with the control cabinet 1, the top surface of the waterproof plates 5 is inclined in the left-right direction, and the top surface of the two waterproof plates 5 is high in the middle and low on both sides after being folded, the control cabinet 1 is symmetrically provided with heat dissipation holes on the top, the waterproof plates 5 are located above the heat dissipation holes, the mounting frame 6 is fixedly connected to the control cabinet 1 on both sides of the top, the mounting frame 6 corresponds to the position of the heat dissipation hole, the waterproof plates 5 are located above the mounting frame 6, and the dust screen 7 is fixedly connected to the mounting frame 6 on the lower side.
[0019] As Figures 1-4 shown, it further includes an electric sliding rail 8, a scraper 9, a push column 10, a rotating shaft 11, a baffle 12, a magnet 13 and a brush 15, the electric sliding rail 8 is fixedly connected to the right side of the mounting frame 6, the scraper 9 is slidably connected in the mounting frame 6, the bottom of the scraper 9 is provided with the brush 15, the scraper 9 is connected with the moving part of the electric sliding rail 8, the scraper 9 is located above the dust screen 7, the push column 10 is fixedly connected to the front side of the scraper 9, the rotating shaft 11 is fixedly connected to the upper left and right sides of the front side of the mounting frame 6, the baffle 12 is rotatably connected between the two rotating shafts 11, the magnets 13 are embeddedly connected to the mounting frame 6 and the baffle 12 on the lower part of the front side, and the magnets 13 on the mounting frame 6 and the magnets 13 on the baffle 12 are adsorbed and matched.
[0020] As Figure 2 shown, it further includes a protective cover 14, the protective cover 14 is fixedly connected to the control cabinet 1, and the bidirectional screw rod 4 is located in the protective cover 14; the protective cover 14 protects the bidirectional screw rod 4, preventing foreign matters from falling on the bidirectional screw rod 4 to cause poor movement of the waterproof plates 5.
[0021] In the initial state, the two waterproof plates 5 are away from each other, and the control cabinet 1 can be cooled through the heat dissipation holes. When it rains, the rain sensor 2 detects the rain and sends a signal, and the controller controls the motor 3 to rotate, thereby driving the bidirectional screw rod 4 to rotate, and the two waterproof plates 5 move towards each other. After the two waterproof plates 5 are moved and closed, the motor 3 is turned off. At this time, the waterproof plates 5 block the top of the mounting frame 6, that is, the heat dissipation holes. In this way, it can prevent rainwater from falling into the control cabinet 1 through the heat dissipation holes and causing damage to the internal parts. The top of the closed waterproof plates 5 is inclined, and the rainwater can flow out along the inclined surface, preventing water from accumulating on the top of the waterproof plates 5 and flowing into the control cabinet 1 through the heat dissipation holes when the waterproof plates 5 are opened.
[0022] At the same time, the controller also controls the electric sliding rail 8 to operate, thereby driving the scraper 9 to move forward. The forward movement of the scraper 9 can scrape the foreign matter on the dust screen 7 forward, and the bristles 15 can sweep the dust screen 7, thereby sweeping out the dust, preventing the foreign matter and dust from affecting the heat dissipation effect. At the same time, the forward movement of the scraper 9 can drive the push column 10 to move forward. When the push column 10 contacts the baffle 12, the push column 10 can push the baffle 12 to rotate upward around the rotating shaft 11, thereby opening the front side of the mounting frame 6, so as to push out the foreign matter and dust from the front side of the mounting frame 6.
[0023] Subsequently, the electric sliding rail 8 drives the scraper 9 to move backward and reset. When the push column 10 moves backward, the baffle 12 rotates downward and resets under the action of its own gravity, and is fixed to the front side of the mounting frame 6 under the adsorption of the magnet 13. After the rain stops, the rain sensor 2 cannot detect rain, and sends a signal. The controller receives the signal and controls the motor 3 to reverse, thereby driving the waterproof plates 5 to move away from each other through the bidirectional screw rod 4, so that the waterproof plates 5 move away from the top of the heat dissipation holes and no longer block the heat dissipation holes. In this way, the rain sensor 2 is used for real-time monitoring. When it rains, the waterproof plates 5 can be closed to block the heat dissipation holes, preventing rainwater from falling into the control cabinet 1 through the heat dissipation holes. At the same time, the scraper 9 and the bristles 15 also clean the foreign matter and dust on the dust screen 7. After the rain stops, the waterproof plates 5 can move away from the top of the heat dissipation holes, ensuring the heat dissipation effect of the control cabinet 1.
