[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0024] Please see Figure 1-4 A security monitoring device for thermal power plants that is easy to install includes a mounting frame 1 and a monitoring device body 5. A base 2 is provided on the upper end of the mounting frame 1, and a mounting block 8 is provided below the monitoring device body 5. A snap-fit ​​mechanism is provided between the base 2 and the mounting block 8.

[0025] The snap-fit ​​mechanism includes a protrusion 3 fixedly connected to the upper end face of the base 2. The lower end face of the mounting block 8 is provided with a groove that matches the protrusion 3. The base 2 and the protrusion 3 are provided with a cavity 4. The left and right end faces of the cavity 4 are fixedly connected to two vertically distributed limiting rods 9. The outer walls of the two limiting rods 9 are slidably connected to two symmetrically distributed L-shaped locking rods 10. The inner wall of the mounting block 8 is provided with two locking holes 11. The locking holes 11 are compatible with the specifications and dimensions of the L-shaped locking rods 10 and their positions are corresponding. The outer walls of the two limiting rods 9 are each sleeved with a spring 12 located between the two L-shaped locking rods 10.

[0026] The locking mechanism also includes a sleeve 13 rotatably connected between the front and rear end faces inside the cavity 4. Two pull ropes 14 are fixedly connected to the outer wall of the sleeve 13. The other ends of the two pull ropes 14 are fixedly connected to two L-shaped locking rods 10 respectively. Two circumferentially distributed spiral grooves 15 are opened on the outer wall of the sleeve 13. A push rod 16 extending to the outside of the base 2 is slidably connected inside the sleeve 13. Two rollers 17 that are slidably connected to the spiral grooves 15 are rotatably connected to the outer wall of the push rod 16.

[0027] In this embodiment: When disassembling the monitoring device body 5, push the push rod 16 inward. The push rod 16 drives the sleeve 13 to rotate counterclockwise through the roller 17 and the spiral groove 15. Then, the pull rope 14 pulls the two L-shaped locking rods 10 to slide relative to each other along the limiting rod 9, so that the L-shaped locking rods 10 are disengaged from the locking hole 11. At this time, the mounting block 8 can be removed from the protrusion 3, thereby removing the monitoring device body 5. When installing the monitoring device body 5, slide the mounting block 8 downward along the protrusion 3. When the lower end of the mounting block 8 is in contact with the L-shaped locking rod 10... When in contact, the mounting block 8 presses the two L-shaped locking rods 10 inward and compresses the spring 12, causing the L-shaped locking rods 10 to retract into the protrusion 3. When the lower end face of the mounting block 8 abuts against the upper end face of the base 2, the L-shaped locking rods 10 are aligned with the locking holes 11. At this time, the two L-shaped locking rods 10 slide outward under the elastic force of the spring 12 and lock into the locking holes 11, thereby fixing the protrusion 3 and the mounting block 8, and thus fixing the monitoring equipment body 5. This utility model installs the monitoring equipment body 5 through a locking mechanism, which is convenient for installation and disassembly.

[0028] As a technical optimization of this utility model, a second servo motor 20 is installed on the lower end face of the mounting bracket 1. The output end of the second servo motor 20 extends to the top of the mounting bracket 1 and is fixedly connected to the base 2. A U-shaped frame 6 is fixedly connected to the upper end face of the mounting block 8. Two connecting shafts that are rotatably connected to the U-shaped frame 6 are fixedly connected to the outer wall of the monitoring equipment body 5. A first servo motor 7 with its output end fixedly connected to one end of the connecting shaft is installed on the outer wall of the U-shaped frame 6.

[0029] In this embodiment: the second servo motor 20 is started, which drives the base 2 to rotate horizontally, thereby adjusting the horizontal angle of the monitoring device body 5. The first servo motor 7 is started, which drives the monitoring device body 5 to rotate up and down, thereby adjusting the pitch angle of the monitoring device body 5.

[0030] As a technical optimization of this utility model, the front end face of the push rod 16 is fixedly connected to the pressure plate 18, and the rear end face of the pressure plate 18 is fixedly connected to two slide rods 19 that are slidably connected to the base 2.

[0031] In this embodiment, the slide bar 19 facilitates the limiting of the push rod 16 and prevents the push rod 16 from rotating axially.

[0032] As a technical optimization of this utility model, the cross-sections of the mounting block 8 and the protrusion 3 are rectangular.

[0033] In this embodiment: by setting the cross-sections of both the mounting block 8 and the protrusion 3 to rectangles, the mounting block 8 is prevented from rotating on the outer wall of the protrusion 3, making it easier to align the L-shaped locking rod 10 with the locking hole 11.

[0034] As a technical optimization of this utility model, the opposite ends of the two L-shaped levers 10 are both inclined upwards.

[0035] In this embodiment: by setting the opposite ends of the two L-shaped locking rods 10 as upward inclined slopes, it is convenient for the mounting block 8 to press the two L-shaped locking rods 10 inward when sliding downward.

[0036] As a technical optimization of this utility model, the outer wall of the mounting bracket 1 is provided with a plurality of symmetrically distributed mounting holes 21.

[0037] In this embodiment: By opening multiple symmetrically distributed mounting holes 21 on the outer wall of the mounting bracket 1, it is convenient to fix the mounting bracket 1 with bolts.

[0038] As a technical optimization of this utility model, a controller is provided on the outer wall of the mounting bracket 1, and the first servo motor 7 and the second servo motor 20 are both electrically connected to the controller.

[0039] In this embodiment, the controller is electrically connected to an external control terminal, which facilitates the normal operation of the first servo motor 7 and the second servo motor 20.

[0040] The working principle and usage process of this utility model are as follows: When disassembling the monitoring equipment body 5, push the push rod 16 inward. The push rod 16 drives the sleeve 13 to rotate counterclockwise through the roller 17 and the spiral groove 15. Then, through the pull rope 14, pull the two L-shaped locking rods 10 to slide relative to each other along the limiting rod 9, so that the L-shaped locking rods 10 are disengaged from the locking hole 11. At this time, the mounting block 8 can be removed from the protrusion 3, thereby removing the monitoring equipment body 5. When installing the monitoring equipment body 5, slide the mounting block 8 downward along the protrusion 3. When the lower end of the mounting block 8 is in contact with the L-shaped... When the locking rods 10 come into contact, the mounting block 8 presses the two L-shaped locking rods 10 inward and compresses the spring 12, causing the L-shaped locking rods 10 to retract into the protrusion 3. When the lower end face of the mounting block 8 abuts against the upper end face of the base 2, the L-shaped locking rods 10 are aligned with the locking hole 11. At this time, the two L-shaped locking rods 10 slide outward under the elastic force of the spring 12 and lock into the locking hole 11, thereby fixing the protrusion 3 and the mounting block 8, and thus fixing the monitoring equipment body 5. This utility model installs the monitoring equipment body 5 through a locking mechanism, which is convenient for installation and disassembly.

Therefore, they should not be construed as limitations on this utility model.

[0042] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
