[0002] The LCU control cabinet is a key piece of equipment in industrial automation systems, specifically designed for water conservancy and hydropower projects (such as hydropower stations, pumping stations, and gate control systems). It is directly deployed at the site of the controlled object to achieve on-site monitoring and management of the equipment.34 Its core functions include data acquisition (such as real-time monitoring of gate opening, water level, and current parameters), control and regulation (supporting manual / automatic mode switching, remote or local operation of equipment start and stop), and communication interaction (linking with a host computer via fiber optic network to achieve fault alarms and remote data transmission).

[0003] In existing technologies, the temperature and smoke sensors in emergency alarm devices for LCU control cabinets on the market are in fixed positions, which cannot quickly monitor local temperature or smoke inside the LCU control cabinet. The monitoring efficiency needs to be improved. There is an urgent need for an LCU control cabinet with monitoring functions to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an LCU control cabinet with monitoring functions to solve the problems mentioned in the background. This utility model adopts a modular installation structure, which can be quickly installed and used in the LCU control cabinet. Moreover, the dual-set staggered reciprocating monitoring structure can quickly monitor the local temperature or local smoke inside the LCU control cabinet.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an LCU control cabinet with monitoring function, comprising an LCU control cabinet body and plastic sliding blocks. A module base plate is horizontally mounted on the lower end of the LCU control cabinet body via bolts. A dual-axis motor is mounted in the middle of the upper end of the module base plate. Both the left and right ends of the dual-axis motor are equipped with active bevel gears. Gear boxes are bolted to the left and right sides of the upper end of the module base plate.

Module side plates are longitudinally welded to the left and right sides of the module base plate, and the two module side plates slide against the left and right ends of the LCU control cabinet body. Bearing seats are horizontally mounted on the upper ends of the two module side plates. Plastic sliding blocks are threaded onto the upper outer end of the first screw and the lower outer end of the second screw. Temperature sensors and smoke sensors are mounted on the inner sides of the two plastic sliding blocks.

[0006] Furthermore, the inner wall of the LCU control cabinet body is provided with control elements, the lower end of the LCU control cabinet body is fixed with a base, the front right side of the LCU control cabinet body is fitted with a cabinet door via a hinge, and multiple heat dissipation holes are provided on the lower sides of both the left and right ends of the LCU control cabinet body.

Detailed Implementation

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] Please see Figures 1-3 This utility model provides a technical solution: an LCU control cabinet with monitoring function, including an LCU control cabinet body 1 and a plastic sliding block 15. A module base plate 4 is horizontally mounted on the lower end of the LCU control cabinet body 1 via bolts. A dual-axis motor 5 is mounted in the middle of the upper end of the module base plate 4. Both the left and right ends of the dual-axis motor 5 are equipped with driving bevel gears 8. Gear boxes 7 are bolted to the left and right sides of the upper end of the module base plate 4. Driven shafts 9 are mounted inside each gear box 7 via bearings. Driven bevel gears 10 are fixed to the outside of each driven shaft 9. A first screw 11 and a second screw 12 are longitudinally fixed to the upper ends of each driven shaft 9, respectively. The module base plate 4... Module side plates 13 are longitudinally welded on both the left and right sides, and the two module side plates 13 are slidably attached to the left and right ends of the LCU control cabinet body 1 respectively. Bearing seats 14 are horizontally installed on the upper ends of the two module side plates 13. Plastic sliding blocks 15 are threadedly fitted on the upper outer end of the first screw 11 and the lower outer end of the second screw 12. Temperature sensors 16 and smoke sensors 17 are installed on the inner sides of the two plastic sliding blocks 15 respectively. This design solves the problem that the temperature sensor and smoke sensor in the original LCU control cabinet emergency alarm device are fixed in position and cannot quickly monitor the local temperature or local smoke in the LCU control cabinet, and the monitoring efficiency needs to be improved.

[0016] As the first embodiment of this utility model: the inner wall of the LCU control cabinet body 1 is provided with control elements, the lower end of the LCU control cabinet body 1 is fixed with a base, the front right side of the LCU control cabinet body 1 is fitted with a cabinet door 3 via a hinge, the lower sides of the left and right ends of the LCU control cabinet body 1 are provided with multiple heat dissipation holes 2, the upper end of the dual-axis motor 5 is fitted with a control panel 6, and the control panel 6, the dual-axis motor 5, the two temperature sensors 16 and the two smoke sensors 17 are all connected to the internal wiring of the LCU control cabinet body 1 via wires, and the control panel 6 controls the dual-axis motor 5 to rotate forward and backward at timed intervals through programming. The control panel 6, the dual-axis motor 5, the two temperature sensors 16, the two smoke sensors 17 and the internal wiring of the LCU control cabinet body 1 are all existing mature equipment and components, and their control principles will not be described in detail.

[0017] Two driven bevel gears 10 mesh with two driving bevel gears 8 respectively. By adding two driven bevel gears 10 to mesh with two driving bevel gears 8, the two driven bevel gears 10 can be driven to rotate when the two driving bevel gears 8 rotate. The upper ends of the first screw 11 and the second screw 12 are respectively installed in two bearing seats 14. By adding the upper ends of the first screw 11 and the second screw 12 to be installed in two bearing seats 14 respectively, the stability of the upper ends of the first screw 11 and the second screw 12 can be ensured. The two plastic sliding blocks 15 are coated with a smooth coating on their opposite outer sides, and the two smooth coatings slide against the inner walls of the two module side plates 13 respectively. By adding the two smooth coatings and sliding against the inner walls of the two module side plates 13 respectively, the two plastic sliding blocks 15 move upward or downward against the inner walls of the module side plates 13 more smoothly. The first screw 11 and the second screw 12 have opposite threads. Because the first screw 11 and the second screw 12 have opposite threads, when the first screw 11 and the second screw 12 rotate, the two plastic sliding blocks 15 can be moved in opposite directions by means of the threads.

[0018] As a second embodiment of this utility model: In actual use, the dual-axis motor 5 is first programmed and controlled by the control panel 6 to rotate in both directions at regular intervals. When the shaft of the dual-axis motor 5 rotates, the two active bevel gears 8 can be rotated, which in turn causes the two driven bevel gears 10 to mesh and rotate. The rotation of the two driven bevel gears 10 drives the two driven shafts 9 to rotate, thereby causing the first screw 11 and the second screw 12 to rotate. Since the threads of the first screw 11 and the second screw 12 are opposite, when the first screw 11 and the second screw 12 rotate, the two plastic sliding blocks 15 can be moved in opposite directions by means of the threads. During this process, the right plastic sliding block 15 slides downward against the inner wall of the right module side plate 13, and the left plastic sliding block 15 slides upward against the inner wall of the left module side plate 13. This allows the two sets of temperature sensors 16 and smoke sensors 17 to move along with the motor, enabling them to quickly monitor the local temperature or local smoke inside the LCU control cabinet body 1.
