Description

Technical Field

[0001] The utility model relates to the field of monitoring devices, in particular to a monitoring device for thermal control equipment in a thermal power plant. Background Technique

[0002] A thermal power plant, abbreviated as a thermal power station, is a factory that uses combustibles (such as coal) as fuel to produce electric energy. Its basic production process is: the fuel heats water to generate steam during combustion, converting the chemical energy of the fuel into heat energy. The steam pressure drives the steam turbine to rotate, converting heat energy into mechanical energy. Then the steam turbine drives the generator to rotate, converting mechanical energy into electric energy. To ensure the safety of the thermal control automation equipment in a thermal power plant, a monitoring device is generally installed around it for real-time monitoring.

[0003] For the existing monitoring device of the thermal control equipment in a thermal power plant, the structure is relatively fixed. When the monitoring device needs to be replaced due to damage, the monitoring device needs to be disassembled from the base wall, which may cause the bolts at the connection between the base of the monitoring device and the base wall to slip with their corresponding threaded grooves, making it inconvenient for the staff to quickly disassemble and install, and affecting the installation and maintenance efficiency.

Specific implementation manners

[0019] The technical solution of this patent will be further described in detail below in conjunction with specific implementation manners.

[0020] Please refer to Figures 1-4 , a monitoring device for thermal control equipment in a thermal power plant, including a mounting base 1. A fixing component 2 is arranged outside the mounting base 1 for pre-installing the mounting base 1 on the wall. A fixing column 3 is fixedly connected to the bottom end of the mounting base 1. A middle part of the bottom end of the fixing column 3 is provided with an insertion slot 4. An insertion joint 5 is movably inserted into the insertion slot 4. The bottom end of the insertion joint 5 is fixedly connected to a camera 6. A plurality of mounting grooves 7 distributed in a circumferential array are formed in an inner wall of the insertion slot 4. A bidirectional threaded rod 8 arranged in a vertical direction is rotatably connected in the mounting groove 7. A driving component 9 linked to the top end of the bidirectional threaded rod 8 is arranged outside the fixing column 3. By setting the driving component 9, the bidirectional threaded rods 8 can be driven to rotate simultaneously. Two moving seats 10 arranged symmetrically are threadedly connected to a surface of the bidirectional threaded rod 8. When the bidirectional threaded rod 8 rotates, the two moving seats 10 will move relatively or in opposite directions on the surface of the bidirectional threaded rod 8. A moving plate 11 is slidably arranged in the mounting groove 7. Support rods 12 are hinged between the two moving seats 10 and the moving plate 11 respectively. A limiting rod 13 is fixedly connected to a side of the moving plate 11 close to the insertion joint 5. A limiting slot 14 corresponding to each limiting rod 13 one by one is formed outside the insertion joint 5. When the driving component 9 drives the bidirectional threaded rod 8 to rotate clockwise, the two moving seats 10 will move in opposite directions simultaneously. The moving plate 11 and the limiting rod 13 are pushed to move towards the insertion joint 5 through cooperation of the support rods 12. During the moving process, the limiting rod 13 will be inserted into the limiting slot 14 to limit and fix the insertion joint 5.

[0021] Furthermore, the fixing component 2 includes two fixing plates 201 fixedly connected to an outer ring of the mounting base 1 and arranged symmetrically. A mounting hole 202 penetrates through a top of the fixing plate 201 in a vertical direction. A fixing bolt 203 is inserted into the mounting hole 202. Before installing the camera 6, the mounting base 1 is fixedly installed on the wall in advance through cooperation of the fixing bolt 203 and the mounting hole 202, which is convenient for subsequent quick disassembly and assembly of the camera 6.

[0022] Further, the driving assembly 9 includes a gear 901 fixedly connected to the top end of the bidirectional threaded rod 8. An outer ring of the fixed column 3 is fixedly connected with a fixed shaft collar 902. An outer part of the fixed shaft collar 902 is rotatably connected with a rotating collar 903. A top part of an inner ring of the rotating collar 903 is fixedly connected with an internal gear ring 904 that is meshed with each gear 901. When the rotating collar 903 rotates, it drives the internal gear ring 904 to rotate, thereby driving each gear 901 to drive the bidirectional threaded rod 8 to rotate synchronously.

[0023] Further, an outer ring of the rotating collar 903 is fixedly connected with a plurality of handles 15 distributed in a circumferential array. The handles 15 are provided to facilitate the rotation of the rotating collar 903.

[0024] Further, an outer wall of the plug connector 5 is fixedly connected with a plurality of guiding blocks 16 distributed in a circumferential array. A bottom end of the fixed column 3 is provided with guiding grooves 17 corresponding to the guiding blocks 16 one by one. When the guiding blocks 16 are inserted into the guiding grooves 17, the limiting grooves 14 will be aligned with the limiting rods 13, thereby improving the convenience of using the device.

[0025] During use, first, the mounting base 1 is fixedly installed on the wall through the cooperation of the fixing bolts 203 and the mounting holes 202. Then, the plug connector 5 is inserted into the socket groove 4. Then, the rotating collar 903 is rotated clockwise through the handle 15. When the rotating collar 903 and the internal gear ring 904 rotate, they drive each gear 901 to rotate synchronously, and then drive each bidirectional threaded rod 8 to rotate. At this time, the two moving seats 10 will move in opposite directions at the same time. Then, the support rod 12 cooperates to push the moving plate 11 and the limiting rod 13 to move towards the plug connector 5. During the movement, the limiting rod 13 will be inserted into the limiting groove 14 to limit and fix the plug connector 5, thereby completing the quick installation of the camera 6. When it is necessary to disassemble and replace the camera 6, only need to rotate the rotating collar 903 counterclockwise. Through the cooperation of the internal gear ring 904, the gear 901, the bidirectional threaded rod 8, the moving seat 10, the support rod 12 and the moving plate 11, the limiting rod 13 is driven to disengage from the limiting groove 14, and the limiting fixation of the plug connector 5 is released, and then the camera 6 can be removed for replacement, avoiding the traditional threaded connection method, and thus facilitating the quick disassembly, replacement and maintenance of the monitoring device.
