Description

Technical Field

[0001] The present invention relates to the technical field of electric power facilities, and in particular to an on-site monitoring device for electric power facilities. Background Art

[0002] Power equipment mainly includes two categories: power generation equipment and power supply equipment. Power generation equipment mainly includes power station boilers, steam turbines, gas turbines, water turbines, generators, transformers, etc. Power supply equipment mainly includes transmission lines of various voltage levels, mutual inductors, contactors, etc. During the use of power equipment, monitoring devices are needed to monitor and operate the power facilities on site. When an emergency occurs, the information is transmitted to the corresponding staff to remind the staff;

[0003] The monitoring device mainly includes a fixed bracket, a camera, monitoring software, etc., wherein the camera is installed on the fixed bracket, and then the fixed bracket is installed on the corresponding wall. The overall structure is simple, but during long-term use, the screws on the fixed bracket often become loose, requiring manual inspection and maintenance, which is time-consuming and labor-intensive and very troublesome. In actual use, long-term use will also cause cracks in the fixed bracket, which also requires manual inspection and maintenance. In addition, during long-term use, dust leakage will occur on the outside of the rotating shaft between the fixed bracket and the camera (shaft dust leakage refers to dust or debris on the rotating shaft that penetrates into the oil seal, causing the rotating shaft to malfunction. The main causes are as follows: 1. The machine has been running for a long time, causing wear and tear, resulting in oil seal failure; 2. The machine has been in a humid environment for a long time, resulting in aging of the oil seal; 3. The machine shaft itself is in an unbalanced state, resulting in continuous friction of the oil seal and thus failure). If the dust leakage is not cleaned for a long time, it will seriously affect the rotation of the rotating shaft, thereby preventing the camera from rotating well, reducing the overall working efficiency of the device. Therefore, an on-site monitoring device for power facilities is provided. Summary of the invention

[0029] like Figure 5 The detection warning component includes a detection frame 114, a cam 111, and a contact plate 112. The detection frame 114 is sleeved on the outer side of the fixed bracket 7. The detection frame 114 and the fixed plate 1 are slidably connected up and down. The cam 111 is fixedly sleeved on the outer side of the upper rotating cylinder 805. The contact plate 112 is located at the lower side of the cam 111 and abuts against the cam 111. The contact plate 112 is connected to the fixed bracket 7 through a second spring 113.

[0030] First, a contact switch is provided on the upper side of the switch rod 116, and the contact switch is connected to one of the warning lights 9 through a wire. When the contact switch and the inner upper side of the right-angle rod 115 are against each other, the warning light 9 is turned on. During the rotation of the rotating cylinder 805, the upper rotating cylinder 805 drives the cam 111 to rotate. With the cooperation of the second spring 113, the contact plate 112 moves up and down back and forth. The contact plate 112 drives the switch rod 116 to move up and down through the third spring 117. The switch rod 116 drives the detection frame 114 to move up and down to detect the fixed bracket 7. If cracks appear on the outer side of the fixed bracket 7, the movement of the detection frame 114 will be seriously hindered, thereby causing the contact switch and the inner upper side of the right-angle rod 115 to be against each other, and the warning light 9 is turned on, thereby reminding the corresponding staff;

[0031] like Figure 6The cleaning assembly includes a transmission cylinder 122, a cleaning cylinder 124, and a cleaning rod 123. The transmission cylinder 122 is located at the lower side of the middle plate 42 and is rotatably connected to the middle plate 42, and the transmission cylinder 122 is rotatably sleeved on the outer side of the first rotating shaft 41. The contact ring is connected to the power shaft 810 through the pulley assembly 121. A plurality of cleaning cylinders 124 are located at the lower side of the contact ring and are fixedly connected to the contact ring. The cleaning rod 123 is slidably connected to the cleaning cylinder 124. The cleaning rod 123 is connected to the bottom of the cleaning cylinder 124 through a fourth spring 126. A cross bar 125 is fixedly connected to the lower side of the cleaning rod 123, and the side wall of the cross bar 125 is against the first rotating shaft 41.

Therefore, the ash leakage outside the first rotating shaft 41 can be simply cleaned, so that the first rotating shaft 41 can always work normally;

[0033] The outer mounting sleeve of the camera 2 is provided with a protective cover 3; a simple protective operation is performed on the camera 2;

[0035] In the present invention, the fixing plate 1 is placed on the side wall of the wall to be installed, the fixing screw 6 is passed through the fixing hole 5, and the fixing screw 6 is screwed into the wall, thereby completing the installation operation of the entire device. After the installation is completed, the camera 2 can be rotated relative to the fixing bracket 7 through the rotating shaft assembly 4, so that the power facility can be monitored on site. The above are all prior arts and no unnecessary details are given. During long-term use, when the threaded rod 804 becomes loose, it will move to the right relative to the fixing plate 1. When the two switch plates 808 are against each other, the motor 809 is started, and the motor 809 drives the power shaft 810 to rotate. The power shaft 810 drives the rotating cylinder 805 to rotate through the first bevel gear 811 and the second bevel gear 812. The rotating cylinder 805 drives the square plate 802 to rotate through the moving rod 801. The square plate 802 drives the fixing screw 6 through the square groove, and the fixing screw 6 is screwed into the wall again, so as to automatically complete the tightening operation of the fixing screw 6. In this process, when the rotating cylinder 8 During the rotation of the cam 111, the upper rotating cylinder 805 drives the cam 111 to rotate. With the cooperation of the second spring 113, the contact plate 112 moves up and down. The contact plate 112 drives the switch rod 116 to move up and down through the third spring 117. The switch rod 116 drives the detection frame 114 to move up and down to detect the fixed bracket 7. If cracks appear on the outside of the fixed bracket 7, the movement of the detection frame 114 will be seriously hindered, which will cause the contact switch and the upper inner side of the right-angle rod 115 to abut against each other, and the warning light 9 will light up. And remind the relevant staff that when the power shaft 810 rotates, under the action of the pulley assembly 121, the transmission cylinder 122 is driven to rotate, the transmission cylinder 122 drives the cleaning cylinder 124 to rotate, the cleaning cylinder 124 drives the cleaning rod 123 to rotate through the fourth spring 126, the cleaning rod 123 drives the cross bar 125 to rotate, and the side wall of the cross bar 125 is against the first rotating shaft 41. Therefore, a simple cleaning operation can be performed on the ash leakage on the outside of the first rotating shaft 41, so that the first rotating shaft 41 can always work normally.
