[0002] An online monitoring device usually refers to a line online monitoring device, which is a device used to automatically, continuously and periodically detect and monitor specific objects. The main equipment of the line online monitoring device is an online monitoring camera. The online monitoring camera is installed on the transmission tower to take pictures of the transmission tower and nearby lines, and the pictures are transmitted to the monitoring station in real time through the Internet of Things module of the online monitoring camera.

[0003] In the prior art, the installation method between the online monitoring camera and the transmission tower is: the online monitoring setting head is installed on the camera hoisting rod, and a flange base is provided at the end of the camera hoisting rod. The flange base is provided with screw holes, and the U-shaped clamp is passed through the tower frame of the tower and then the two ends of the U-shaped clamp are passed through the two screw holes on the flange base. At the same time, the two ends of the U-shaped clamp are provided with threads, and nuts are screwed on the two ends of the U-shaped clamp, so as to limit the flange base on the U-shaped clamp, and complete the installation between the online monitoring camera and the transmission tower.

[0004] However, the installation structure between the online monitoring camera and the transmission tower in the online monitoring device in the prior art is too simple. The nut and the U-shaped clamp are connected by a threaded connection, and no anti-loosening measures are designed. The tightening of the threaded connection depends entirely on the friction between the threads. The online monitoring device is installed outdoors and usually installed at a high place on the transmission tower. The environment has a large temperature difference between day and night and frequent air flow. Under the influence of the external force caused by the temperature difference and wind, the friction between the threads will weaken or even disappear at certain times, which will cause the nut to gradually loosen and cause the online monitoring device to fall from the tower.

[0019] Embodiment 1

[0020] See also Figures 1 to 4 The utility model provides a technical solution: an online monitoring device, comprising: an online monitoring camera 1 and a transmission tower 4, a camera hoisting frame 2 is arranged at the top of the online monitoring camera 1, a flange base 3 is arranged at the other end of the camera hoisting frame 2, a screw hole is opened on the surface of the flange base 3, one end of a U-shaped clamp 5 is movably inserted in the screw hole of the flange base 3, the U-shaped clamp 5 is sleeved on the surface of the transmission tower 4, threads are opened at both ends of the U-shaped clamp 5 and nuts 6 are installed through threaded connection, a block groove 9 is opened on the surface of the flange base 3, one end of a mobile clamp 8 is movably inserted in the block groove 9, the other end of the mobile clamp 8 is provided with an inclined surface, a nut clamp 7 is arranged at one end of the nut 6, and the other end of the nut clamp 7 is provided with an inclined surface, the inclined surfaces of the nut clamp 7 and the mobile clamp 8 are in opposite directions, and a spring 12 is fixed to one end of the mobile clamp 8 extending into the block groove 9, and the other end of the spring 12 is fixed to the inner wall of the block groove 9.

[0021] In actual use, the U-shaped clamp 5 is sleeved on the surface of the transmission tower frame 4, and then the two ends of the U-shaped clamp 5 are respectively inserted into the two sets of screw holes opened on the surface of the flange base 3, and then the nut 6 is screwed on the two ends of the U-shaped clamp 5. It is necessary to ensure that the end of the nut 6 fixed with the nut clamp 7 faces the flange base 3. When the nut 6 is screwed close to the flange base 3, the nut clamp 7 contacts the moving clamp 8. Because the inclined surfaces of the nut clamp 7 and the moving clamp 8 face opposite directions, when the nut 6 continues to be tightened, the inclined surface of the nut clamp 7 slides over the inclined surface of the moving clamp 8, and the moving clamp 8 is pushed into the depth of the clamp groove 9 without affecting the tightening of the nut 6. After the end of the nut clamp 7 away from the nut 6 abuts against the surface of the flange base 3, it means that the nut 6 has been fully tightened. At this time, under the elastic force of the spring 12, one end of the moving block 8 abuts against the surface of the nut 6, and the end of the moving block 8 without a bevel abuts against the end of the nut block 7 without a bevel, so that the moving block 8 limits the movement of the nut block 7 in the direction of loosening the nut 6, and then the moving block 8 limits the loosening of the nut 6, thereby realizing the anti-loosening function of the nut 6, so that the flange base 3 is firmly installed on the U-shaped clamp 5, ensuring that the camera hoisting frame 2 and the online monitoring camera 1 installed on the camera hoisting frame 2 are firmly installed, and the online monitoring camera 1 can monitor the transmission tower frame 4 and the lines around the transmission tower frame 4 and transmit the monitoring images to the monitoring station in real time.

[0022] Embodiment 2

[0023] On the basis of Example 1, in order to facilitate the removal of the online monitoring camera 1, several groups of nut blocks 7, mobile blocks 8 and block grooves 9 are provided, and several groups of mobile blocks 8 and block grooves 9 are distributed in a circle around the screw holes of the flange base 3, and several groups of nut blocks 7 are distributed in a circle on the surface of the nut 6. A pull rod hole 10 is opened at the end of the flange base 3 away from the nut 6. The pull rod hole 10 is provided with several groups, and several groups of pull rod holes 10 are distributed and connected with several groups of block grooves 9. A pull rod 11 is movably inserted in the pull rod hole 10, one end of the pull rod 11 is fixed on the surface of the mobile block 8, and a pull ring 13 is fixed on the other end of the pull rod 11. The pull ring 13 is a circular ring structure, and the pull ring 13 is sleeved on the surface of the U-shaped clamp 5.

[0024] When it is necessary to actively remove the online monitoring camera 1, pull the pull ring 13 in the direction away from the nut 6. The movement of the pull ring 13 causes the movable block 8 to move in the same direction through the pull rod 11 in the pull rod hole 10, so that the movable block 8 is completely retracted into the block groove 9. The end of the movable block 8 without the inclined surface no longer rests on the end surface of the nut block 7 without the inclined surface, and the anti-loosening is cancelled. The nut 6 can be screwed in the loosening direction. After unscrewing the nut 6 from the U-shaped clamp 5, the online monitoring camera 1, the camera hanging frame 2 and the flange base 3 can be removed from the U-shaped clamp 5, and the removal of the online monitoring camera 1 can be completed conveniently.

[0025] In actual use, the U-shaped clamp 5 is sleeved on the surface of the transmission tower frame 4, and then the two ends of the U-shaped clamp 5 are respectively inserted into the two sets of screw holes opened on the surface of the flange base 3, and then the nut 6 is screwed on the two ends of the U-shaped clamp 5. It is necessary to ensure that the end of the nut 6 fixed with the nut clamp 7 faces the flange base 3. When the nut 6 is screwed close to the flange base 3, the nut clamp 7 contacts the moving clamp 8. Because the inclined surfaces of the nut clamp 7 and the moving clamp 8 face oppositely, when the nut 6 continues to be tightened, the inclined surface of the nut clamp 7 moves from the moving clamp 8 to the moving clamp 8. The movable clamping block 8 slides over the inclined surface of the movable clamping block 8, and the movable clamping block 8 is pushed into the depth of the clamping block groove 9 without affecting the tightening of the nut 6. After the end of the nut clamping block 7 away from the nut 6 abuts against the surface of the flange base 3, it means that the nut 6 has been completely tightened. At this time, under the elastic force of the spring 12, one end of the movable clamping block 8 abuts against the surface of the nut 6, and the end of the movable clamping block 8 without an inclined surface abuts against the end of the nut clamping block 7 without an inclined surface, so that the movable clamping block 8 has a limiting effect on the movement of the nut clamping block 7 in the direction of loosening the nut 6, thereby The movable block 8 limits the loosening of the nut 6, thereby realizing the anti-loosening function of the nut 6, so that the flange base 3 is firmly installed on the U-shaped clamp 5, ensuring that the camera hoisting frame 2 and the online monitoring camera 1 installed on the camera hoisting frame 2 are firmly installed. The online monitoring camera 1 can monitor the transmission tower frame 4 and the lines around the transmission tower frame 4 and transmit the monitoring images to the monitoring station in real time; when it is necessary to actively remove the online monitoring camera 1, pull the pull ring in the direction away from the nut 6. 13. The movement of the pull ring 13 enables the movable block 8 to move in the same direction through the pull rod 11 in the pull rod hole 10, so that the movable block 8 is completely retracted into the block groove 9. The end of the movable block 8 without the inclined surface no longer abuts against the end surface of the nut block 7 without the inclined surface, and the anti-loosening function is cancelled. The nut 6 can be screwed in the loosening direction. After the nut 6 is unscrewed from the U-shaped clamp 5, the online monitoring camera 1, the camera hanging frame 2 and the flange base 3 can be removed from the U-shaped clamp 5, and the removal of the online monitoring camera 1 can be completed conveniently.
