Description

Technical Field

[0001] The present invention relates to the technical field of monitoring devices, and in particular to a high-precision engineering structure dynamic monitoring device combining a GNSS and a gyroscope. Background Art

[0002] The high-precision engineering structure dynamic monitoring device combining GNSS and gyroscope uses GNSS to provide accurate position data and gyroscope to provide angular velocity information. The combination of the two can realize real-time monitoring of the dynamic behavior of the structure. GNSS provides wide-area positioning capabilities, while the gyroscope supplements the high-precision angle measurement under dynamic conditions, ensuring the high accuracy and real-time nature of the monitoring results. This device is widely used in health monitoring and dynamic analysis of bridges, buildings and other important engineering structures to help prevent structural damage and safety hazards.

[0003] However, the monitoring device currently has the following problems: in the monitoring device, after the mushroom-head antenna is connected to the navigator interface through a line, the line in the middle will fall to the ground because it is relatively long. The fallen line will become a hidden danger of tripping pedestrians or other accidents, affecting the safety of equipment and personnel. Therefore, we propose a high-precision engineering structure dynamic monitoring device that combines GNSS and gyroscope. Summary of the invention

[0026] See also Figure 1-Figure 7One embodiment of the present invention is: a high-precision engineering structure dynamic monitoring device combining GNSS and gyroscope, including a placement plate 1, two mushroom-head antennas 2 are clamped on the top of the placement plate 1, a navigator 3 is clamped on the top of the placement plate 1, a mounting frame 4 is fixedly connected to the bottom of the navigator 3, a magnetic block 5 is fixedly connected to the bottom of the inner wall of the mounting frame 4, and it is characterized in that: a plurality of support frames 8 are fixedly connected to the side of the navigator 3, a plurality of support frames 8 are rotatably connected to the same rotating column 9 on the inner walls, handles 10 are fixedly connected to both ends of the rotating column 9, and an anti-loosening device 6 is arranged on the side of the navigator 3. Through the arrangement of the above structure, the rotating column 9 is rotated by the handle 10, so that the line is wound around the surface of the rotating column 9, so as to avoid the line being too long, and the middle line will fall to the ground, thereby causing the problem of tripping pedestrians or other potential accidents.

[0027] The outer wall of the rotating column 9 is fixedly connected to a fixing ring 11, the outer wall of the fixing ring 11 is fixedly connected to a telescopic block 12, the bottom of the support frame 8 is fixedly connected to a fixing groove ring 13, the side of the fixing groove ring 13 close to the handle 10 is fixedly connected to an arc block 14, the side of the support frame 8 is fixedly connected to a notch ring 15, the bottom notch of the notch ring 15 is slidably connected to a T-shaped counterweight block 16, the bottom of the T-shaped counterweight block 16 is fixedly connected to an arc plate 17, the side of the arc plate 17 close to the fixing groove ring 13 is fixedly connected to a cross bar 18, the inner wall of the arc plate 17 is fixedly connected to the fixing groove ring 13.

The arc block 14 is located on the displacement track of the telescopic block 12, and the cross bar 18 is located on the displacement track of the telescopic block 12.

The reciprocating motion of the brush block 19 can clean up the debris on the surface of the line, thereby avoiding the problem of the debris scratching the line when the line is circled.

[0028] The anti-loosening device 6 includes two F-type plates 61, the sides of the two F-type plates 61 are fixedly connected to the sides of the navigator 3, two rollers 62 are rotatably connected between the lower parts of the two F-type plates 61, a belt 63 is connected between the two rollers 62, one of the rollers 62 is fixedly connected to a wheel 64 near the outer wall of the F-type plate 61, a wheel 2 65 is fixedly connected to the outer wall of the rotating column 9, a track 66 is connected between the wheel 2 65 and the wheel 1 64, two slide grooves 67 are provided on the upper sides of the two F-type plates 61, and the inner walls of the four slide grooves 67 are slidably connected to sliders 68, and two are grouped together, and each group is connected in pairs. A spring 1 is provided on the top of the slider 68 and the top of the inner wall of the slide groove 67. A rotating rod 69 is penetrated and rotatably connected to the side of each group of sliders 68. The outer walls of the two rotating rods 69 are fixedly connected to roller 2 610. A belt 2 611 is transmission-connected between the two rollers 610. Both ends of the roller 2 610 are in contact with the sides of the two F-shaped plates 61. Through the arrangement of the above structure, the movement of the roller 2 610 will drive the belt 2 611 to move in the direction of the belt 1 63, so that the belt 2 611 flattens the moving line toward the belt 1 63, thereby avoiding the problem of the curved line becoming loose when winding.

[0029] Both ends of the two rotating rods 69 are fixedly connected with a block 612, and the outer wall of the block 612 is clamped with a one-way bearing 613, and the side of the one-way bearing 613 is in contact with the side of the F-type plate 61. Through the setting of the above structure, the one-way bearing 613 will prevent the rotating rod 69 from rotating in the opposite direction through the block 612. The rotating rod 69 cannot rotate in the opposite direction, and the belt 2 611 cannot rotate in the opposite direction through the roller 2 610, thereby avoiding the problem of the line being loosened at the interface between the line and the navigator 3 due to external tension.

[0030] When in use, take out the two mushroom head antennas 2 from the placement plate 1, magnetically fix one of the mushroom head antennas 2 to the front position of the roof, and magnetically fix the other mushroom head antenna 2 to the rear position of the roof, keep the position line of the two mushroom head antennas 2 parallel to the longitudinal axis of the vehicle as much as possible, then face the navigator 3 directly in front of the vehicle, magnetically fix it close to the mushroom head antenna 2, connect the line to the interface of the navigator 3, and then place the line on the surface of the rotating column 9, rotate the rotating column 9 by the handle 10, so that the line is wound around the surface of the rotating column 9, so as to avoid the line being too long and the middle line falling to the ground, thus causing the problem of tripping pedestrians or other potential accidents; the rotation of the rotating column 9 will drive the fixing ring 11 to rotate, and the rotation of the fixing ring 11 will drive the telescopic block 12 to rotate, and the telescopic block 12 will contact the cross bar 18 when rotating, thereby driving The cross bar 18 moves along the fixed groove ring 13 in the direction away from the navigator 3, and the movement of the cross bar 18 will drive the arc plate 17 to move, and the movement of the arc plate 17 will drive the T-shaped counterweight block 16 to move at the notch of the notch ring 15. At the same time, the movement of the arc plate 17 will drive the brush block 19 to move. When the telescopic block 12 moves and contacts the arc block 14, the telescopic block 12 will be squeezed by the arc block 14, so that the telescopic block 12 can move from the circumferential surface of the cross bar 18, so that the telescopic block 12 no longer contacts the cross bar 18. Therefore, the T-shaped counterweight block 16 will drive the arc plate 17, the cross bar 18 and the brush block 19 to reset under the action of its own gravity, and so on, so that the brush block 19 can realize reciprocating motion. The reciprocating motion of the brush block 19 can clean up the debris on the surface of the line, thereby avoiding the problem of debris scratching the line when the line is circling.

[0031] Place the line between belt 1 63 and belt 2 611, the rotation of rotating column 9 will drive rotating wheel 2 65 to rotate, rotating wheel 2 65 will drive rotating wheel 1 64 to rotate through track 66, the rotation of rotating wheel 1 64 will rotate belt 1 63, the rotation of belt 1 63 will make the line move better on the surface of belt 1 63, the movement of the line will also make belt 2 611 rotate, under the elastic force of the spring corresponding to slider 68, slider 68 will drive rotating rod 69 to move in the direction of belt 1 63, the movement of rotating rod 69 will drive rotating roller 2 610 to move, the movement of rotating roller 2 610 will drive belt 2 611 to Belt 1 63 moves in the direction of the belt 2 611, so that the belt 2 611 can flatten the moving line toward the belt 1 63, thereby avoiding the problem of the curved line becoming loose when winding; the one-way bearing 613 is installed on the block 612 before the line is wound. After the line is wound, because the one-way bearing 613 can only rotate in one direction, when the line is subjected to external tension, the one-way bearing 613 will prevent the rotating rod 69 from rotating in the reverse direction through the block 612. The rotating rod 69 cannot rotate in the reverse direction, which will prevent the belt 2 611 from rotating in the reverse direction through the roller 2 610, thereby avoiding the problem of the line being subjected to external tension and causing the line to become loose at the interface with the navigator 3.

[0034] When in use, when the navigator 3 is facing the front of the vehicle and is magnetically fixed close to the mushroom head antenna 2, the movement of the arc plate 17 will drive the L-shaped hook block 1 710 to move, and the movement of the L-shaped hook block 1 710 will pull the T-shaped push-pull plate 74 to move through the L-shaped hook block 2 711, so that the cavity block 73 draws air from the adsorption plate 71 through the air pipe 72, so that negative pressure is generated at the suction nozzle of the adsorption plate 71, and the suction nozzle of the adsorption plate 71 will adsorb and fix the surface of the car, thereby avoiding the problem of displacement or falling of the navigator 3 due to external tension; the rotating rod 69 will fix the T-shaped push-pull plate 74 through the clamping block 612, thereby avoiding The T-shaped push-pull plate 74 is reset by the corresponding spring force, and air is blown to the adsorption plate 71 through the air pipe 72, so that the adsorption plate 71 is difficult to be adsorbed and fixed to the surface of the car; the T-shaped push-pull plate 74 will squeeze the return bag 713 when moving, and the return bag 713 will make the water inside the water storage cotton 714 flow to the adsorption plate 71 through the guide pipe 715 after being squeezed, thereby further enhancing the adsorption force of the adsorption plate 71; when it needs to be taken out, the T-shaped push-pull plate 74 is reset by the corresponding spring force, and air is blown to the adsorption plate 71 through the air pipe 72, so that the adsorption plate 71 is no longer adsorbed on the surface of the car, and it is convenient to take out.
