[0037] Thermal power plants need to transport fuel and other equipment during the production process. During the transportation process, monitoring equipment is needed to provide intelligent warnings to prevent malfunctions of the transportation equipment and lead to fuel shortages. The installation of monitoring equipment in the existing technology is relatively cumbersome, which brings many inconveniences to inspection and maintenance.

[0038] In order to solve the above problems, the following embodiments are provided:

[0039] Embodiment 1

[0040] See also Figure 1-7 , provides an intelligent early warning device for thermal power plant faults based on big data analysis, including: a support frame 1, a fixing mechanism 2 fixed on the support frame 1, and a camera early warning component.

[0041] Specifically, the fixing mechanism 2 includes a square box 21, a double-headed threaded rod 22, and a pair of sliders 24 arranged inside the square box 21. The sliders 24 are connected to the rotating shafts on both sides with rotating rods 26. The other ends of the two rotating rods 26 on the same side of the slider 24 are connected to the moving seat 27. The double-headed threaded rod 22 vertically threads through the two sliders 24. A pair of mounting holes 29 are opened at the bottom of the square box 21. A limiting mechanism 211 is arranged inside the square box 21. The limiting mechanism 211 includes a rectangular box 212 and a limiting pin 213. The limiting pin 213 is slidably arranged in the rectangular box 212. The limiting pin 213 An elastic member 214 is fixedly provided on the upper portion, and the other end of the elastic member 214 is fixedly connected to the rectangular box 212. A pull rod 215 is fixedly provided on the limit pin 213. Each pair of pull rods 215 are fixedly connected by a cross bar 216. The camera warning component includes a pair of limit blocks 32 that penetrate into the square box 21. The two movable seats 27 are on the same vertical line as the limit blocks 32. Limit slots 34 are provided on both sides of the limit blocks 32. The limit pin 213 is inserted into the limit slot 34. The double-headed threaded rod 22 penetrates the square box 21, and a knob is fixedly provided at one end of the double-headed threaded rod 22 that penetrates the square box 21.

[0042] When in use, lift the camera assembly and insert the limit block 32 into the square box 21 through the mounting hole 29. When inserted, the limit block 32 will squeeze the inclined surface of the end of the limit pin 213 to move it inward and squeeze the elastic member 214. When the limit block 32 is fully inserted, the elastic member 214 pushes the limit pin 213 to insert into the limit slot 34 to preliminarily fix the camera assembly. The double-headed threaded rod 22 is rotated by the knob, and the double-headed threaded rod 22 drives the slider 24 to move toward the middle. The slider 24 pushes the moving seat 27 away from the double-headed threaded rod 22 through the rotating rod 26, and the moving seat 27 fixes and squeezes the side wall of the limit block 32. The camera assembly is fixed again to complete the installation of the camera assembly. When disassembling it, the double-headed threaded rod 22 is rotated in the opposite direction. The double-headed threaded rod 22 drives the slider 24 to move to both ends respectively, and the movable seat 27 is pulled toward the double-headed threaded rod 22 by the rotating rod 26 to cancel the squeezing of the limit block 32. When the slider 24 continues to move, it will push the pull rod 215 to move together. The pull rod 215 pulls the limit pin 213 to move into the rectangular box 212 and squeezes the elastic part 214 to make the limit pin 213 disengage from the limit slot 34, cancel the limit on the limit block 32, and allow the camera warning assembly to be removed.

[0043] The video warning assembly includes an adjustment assembly 3 and a monitoring device 4 fixed below the adjustment assembly 3. The adjustment assembly 3 includes a shell 31. A limit block 32 is fixed to the upper end surface of the shell 31. Limit rods 28 are fixed on opposite sides of the two movable seats 27. Limit holes 33 are provided on opposite sides of a pair of limit blocks 32. When the double-headed threaded rod 22 is tightened, the movable seat 27 moves away from the double-headed threaded rod 22 and inserts the limit rod 28 into the inside of the limit hole 33.

[0044] When in use, the double-headed threaded rod 22 pushes the movable seat 27 to move toward the limit block 32 through the slider 24 and the rotating rod 26, and the movable seat 27 drives the limit rod 28 to be inserted into the limit hole 33, thereby completely limiting the limit block 32, making the camera warning component installed more firmly.

[0046] When in use, the motor 37 is started, the motor 37 drives the first gear 38 to rotate, the first gear 38 drives the second gear 39 to rotate, the second gear 39 drives the disc 35 to rotate through the inner gear ring 36, the disc 35 drives the monitoring device 4 to rotate through the lower hanging plate 351 to adjust the direction, the electric push rod 353 is started, the electric push rod 353 drives the third gear 354 to rotate through the rack 355, the third gear 354 drives the monitoring device 4 to rotate through the circular shaft 41 to adjust the up and down angles.

[0047] The double-headed threaded rod 22 passes through the square box 21, and multiple limiting mechanisms 211 are symmetrically arranged on both sides of the mounting hole 29. The pull rods 215 are all located at the center of the elastic member 214. The pull rods 215 on the same side are connected by a cross bar 216. A pair of sliders 24 are symmetrically arranged on different thread directions of the double-headed threaded rod 22, and a pair of sliders 24 are located between a pair of cross bars 216.

[0048] When in use, the limit block 32 needs to be fully inserted into the mounting hole 29 before it can be installed. The double-headed threaded rod 22 passes through the end of the square box 21 and a knob can be fixed to facilitate its rotation. The symmetrical setting of the limit mechanism 211 makes the limit pin 213 have a more even and stable bearing capacity for the monitoring and early warning component. The symmetrical setting of the slider 24 makes the double-headed threaded rod 22 drive the slider 24 to push the moving seat 27 through the rotating rod 26 with the same force to prevent it from deflecting.

[0049] Embodiment 2

[0050] In order to cooperate with the first embodiment, a method for using a thermal power plant fault intelligent early warning device based on big data analysis is also provided, which is applied to any one of the thermal power plant fault intelligent early warning devices based on big data analysis recorded in the first embodiment, and includes the following steps:

[0051] S1. Use the monitoring device 4 to photograph the working status of the conveying equipment during transportation, and upload the photographed images to the host computer for data analysis.

[0052] When the fuel moves on the conveyor belt, the monitoring device 4 can capture whether the movement state of the fuel on the conveyor belt is normal, and the images captured by the monitoring device 4 are transmitted to the host computer via a wireless network.

[0053] S2. Compare the captured image with the normal operating status of the device through the image analysis module, and feed back the comparison result to the host computer.

[0054] When the host computer receives the image transmitted by the monitoring device 4, the image analysis module compares the transmitted image with the normal working state image, and the image motion state is superimposed and compared for analysis, and the analysis result is fed back to the host computer.

[0055] S3. The host computer compares the comparison result with the preset conditions and determines whether to issue a preventive alarm based on the comparison result.

[0056] The host computer compares the analysis results of the image analysis module with the pre-set conditions to determine whether the warning value is exceeded. Only when the warning value is exceeded will a preventive alarm be issued.

[0057] Among them, the installation method of the intelligent early warning device for thermal power plant faults based on big data analysis includes the following steps:

[0058] S4. The limit block 32 on the camera warning assembly is inserted into the square box 21.

[0059] Align the limit block 32 with the mounting hole 29 at the bottom of the square box 21 , and lift the camera warning assembly upwards so that the limit block 32 is completely inserted into the square box 21 through the mounting hole 29 .

[0060] S5. The elastic member 214 pushes the limiting pin 213 to insert into the limiting slot 34 to preliminarily fix the camera warning assembly.

[0061] When the limit block 32 is fully inserted into the square box 21, the limit pin 213 will be inserted into the limit slot 34, and the camera warning assembly will be initially fixed by the limit pin 213 so that it will be hung on the bottom of the square box 21 and will not fall off, and no manual support is required during fixation.

[0062] S6. Rotate the double-threaded rod 22, which drives a pair of sliders 24 to move toward the middle. The sliders 24 push the moving seat 27 through the rotating rod 26 until the moving seat 27 presses against the limit block 32, thereby finally fixing the camera warning assembly and completing the installation.

[0063] After the initial fixation, it needs to be finally fixed to prevent it from falling. The double-headed threaded rod 22 is rotated to drive the moving seat 27 through the slider 24 and the rotating rod 26 to drive the limit rod 28 to be inserted into the limit hole 33, and the moving seat 27 is pressed against the limit block 32 so that it can firmly fix the camera warning component.

[0064] The above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them. Anyone familiar with the technology can modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
