[0002] When the power equipment in a power station is working, human intervention is seldom required. The normal and stable operation of a whole set of power generation equipment cannot be separated from the real-time monitoring of monitoring equipment. The sound and light monitoring equipment is widely used in this field due to its real-time monitoring and sensitivity. At present, when installing wall-mounted sound and light monitoring equipment, due to the height restrictions required for installation, workers need to climb high to install it, and they also need to climb high for subsequent maintenance, which is very dangerous.

[0037] The up-and-down movable connecting rod 9 has several connecting rods 9 and is distributed up and down. Adjacent connecting rods 9 are connected by several connecting rod connecting columns 10. The monitor base 2 is fixed to the connecting rod connecting column 10 by bolts, and the bolts are movably inserted into the fixed base slide groove 3-1 and the movable base slide groove 4-1; the other end of the above-mentioned pull rope 8 is fixed to the middle part of the uppermost up-and-down movable connecting rod 9; the left and right ends of the up-and-down movable connecting rod 9 are both movably arranged up and down in the fixed base slide groove 3-1 and the movable base slide groove 4-1; the left and right ends of the up-and-down movable connecting rod 9 are both sleeved and fixed with a limiting plate 11, which plays a left and right limiting role on the movement of the up-and-down movable connecting rod 9.

[0039] Embodiment 2:

[0040] See also Figure 3 , Figure 5 , Figure 6 and Figure 8As shown, this embodiment is based on the embodiment one, and positioning columns 14 are fixed at the four corners of the top of the movable base 4, and the positioning columns 14 are movably inserted into the positioning slots 3-3 opened at the four corners of the bottom of the fixed base 3; a pressing protrusion 18 is movably arranged in one of the positioning slots 3-3, and the outer end of the pressing protrusion 18 is a structure with a notched corner on the lower surface, and the pressing protrusion 18 is movably arranged in a pressing switch slot 3-4 opened on the rear side of the fixed base slide slot 3-1, and a pressing switch 15 is fixed in the pressing switch slot 3-4, and the control end of the pressing switch 15 is movably abutted against the pressing rod 17, and the pressing rod 17 is fixed at the inner end of the pressing protrusion 18, and a spring 16 is sleeved on the pressing rod 17, and the two ends of the spring 16 are respectively abutted against the pressing protrusion 18 and the switch seat of the pressing switch 15; the pressing switch 15 is electrically connected to the forward and reverse reduction motor 5.

[0041] With the above design, when the movable base 4 is docked with the fixed base 3, the positioning column 14 is inserted into the positioning slot 3-3, and one of the positioning columns 14 contacts the pressing protrusion 18 and pushes it into the pressing switch slot 3-4. During the pushing process, the pressing rod 17 is driven to move inward until it contacts the control end of the pressing switch 15 and realizes the pressing operation, thereby realizing the opening of the forward and reverse reduction motor 5; when the movable base 4 is removed from the lower end of the fixed base 3, the positioning column 14 is driven to disengage from the positioning slot 3-3. During this process, the control end of the pressing switch 15 loses the pressing force, and the forward and reverse reduction motor 5 is turned off.

[0042] When using the present invention, during the first installation, the monitor base 2 is fixed together with the monitor 1 on the connecting rod connecting column 10 with bolts. At this time, the up-and-down movable connecting rod 9 is located at the highest point of the installation position, and then the fixed base 3 is installed at a height slightly higher than the required monitoring height with the wall bolts 19; the movable base 4 is docked to the lower end of the fixed base 3, and the positioning column 14 is inserted into the positioning slot 3-3. One of the positioning columns 14 contacts the pressing protrusion 18 and pushes it into the pressing switch slot 3-4. During the pushing process, the pressing rod 17 is driven to move inward until it contacts the control end of the pressing switch 15 and realizes the pressing operation, thereby realizing the opening of the forward and reverse reduction motor 5. The forward and reverse reduction motor 5 rotates forward, and after the pull rope 8 is lowered to a certain height, the movable base 4 is removed from the lower end of the fixed base 3, thereby driving the positioning column 14 to disengage from the positioning slot 3-3. During this process, the control end of the pressing switch 15 loses the pressing force, and the forward and reverse reduction motor 5 is turned off, thereby realizing the adjustment of the high monitoring position of the monitor 1;

[0043] When the monitor 1 needs to be maintained or repaired after being used for a period of time, the movable base 4 is docked at the lower end of the fixed base 3 again. At this time, the positioning column 14 is inserted into the positioning slot 3-3, and one of the positioning columns 14 contacts the pressing protrusion 18 and pushes it into the pressing switch slot 3-4. During the pushing process, the pressing rod 17 is driven to move inward until it contacts the control end of the pressing switch 15 and realizes the pressing operation, thereby realizing the opening of the forward and reverse reduction motor 5, and the forward and reverse reduction motor 5 is reversed, so that the pull rope 8 is used to lift up and the monitor 1 is lifted to the highest point of the installation position. Then move the movable base 4 downward, thereby driving the positioning column 14 to move downward. When the positioning column 14 is disengaged from the pressing protrusion 18, the forward and reverse reduction motor 5 is turned off, and the movable base 4 is moved up again, so that the positioning column 14 contacts the pressing protrusion 18 again. At this time, the forward and reverse reduction motor 5 works forward, driving the pull rope 8 to descend, until the monitor 1 moves up and down from the fixed base 3 to the movable base 4, and finally reaches the lower part of the movable base 4. At this time, the movable base 4 can be completely removed from the fixed base 3, and the forward and reverse reduction motor 5 stops working, thereby realizing the maintenance operation of the monitor 1;

[0044] After completing the inspection and maintenance operation, the movable base 4 is docked at the lower end of the fixed base 3 again. At this time, the positioning column 14 is inserted into the positioning slot 3-3, and the positioning column 14 contacts the pressing protrusion 18 and pushes it into the pressing switch slot 3-4. During the pushing process, the pressing rod 17 is driven to move inward until it contacts the control end of the pressing switch 15 and realizes the pressing operation, thereby realizing the opening of the forward and reverse reduction motor 5, and the forward and reverse reduction motor 5 is reversed, so as to use the pull rope 8 to lift up and drive the monitor base 2 to move on the movable base 4 to the fixed base 3 until it reaches the height required for monitoring, and then the monitoring can be resumed.

[0045] After adopting the above structure, the beneficial effects of this specific implementation are as follows:

[0046] 1. Use the fixed base and the movable base to install and disassemble the monitor, avoiding the workers from climbing up many times, which is safer and more convenient;

[0047] 2. The positioning column and the push switch cooperate with each other to realize the control of the forward and reverse speed reduction motor during the connection between the fixed base and the movable base, saving operation time;

[0048] 3. The detachable setting of the movable base saves the space occupied by the entire device. At the same time, one movable base can work in conjunction with multiple fixed bases, and has strong adaptability.

[0049] For those skilled in the art, they can modify the technical solutions described in the aforementioned embodiments and make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
