Description

Technical Field

[0001] The utility model relates to the field of distribution network pole tower tilt monitoring, in particular to a dual-axis tilt sensor suitable for distribution network pole tower tilt monitoring. Background Art

[0002] In existing technology, tilt sensors are commonly used to monitor the inclination of distribution network towers. Dual-axis tilt sensors are widely used in this field because they offer performance comparable to that of horizontal ranging instruments. To monitor the inclination of distribution network towers, the dual-axis tilt sensor must be fixed to the tower and kept facing downward.

[0003] At present, the dual-axis tilt sensor is generally fixed to the distribution network pole tower by a clamping plate set on it. Since the relative positions of the clamping plate and the dual-axis tilt sensor are fixed, in order to keep the dual-axis tilt sensor at the target angle, the installation direction of the clamping plate is often relatively fixed. Therefore, the clamping plate usually needs to be installed on the vertical or horizontal pole or bracket on the distribution network pole tower. For the specific installation method, please refer to the application number 202122805108.6, and the patent name is a Chinese utility model patent for a power pole tower tilt monitoring device.

[0004] However, since the distribution network tower is a tower-shaped tower with an overall outline that gradually shrinks from bottom to top, it is not composed entirely of vertical or horizontal poles. The current dual-axis tilt sensor cannot adjust the installation angle of the clamping plate as needed, which increases the installation limitations. Utility Model Content

[0005] The utility model aims to provide a dual-axis tilt sensor suitable for monitoring the inclination of distribution network towers, so as to solve the technical problem in the prior art that the installation angle of the clamping plate cannot be adjusted.

[0006] In order to solve the above technical problems, the specific solution adopted by the utility model is as follows: a dual-axis tilt sensor suitable for monitoring the tilt of distribution network towers, comprising a box and a dual-axis tilt sensor body arranged in the box, a rotating shaft is installed on the box, one end of the rotating shaft is located in the box and is rotatably mounted on the inner side of the front wall of the box, and the other end passes through the rear wall of the box and is fixed with a turntable, a worm gear is sleeved on the rotating shaft located in the box, a worm gear adapted to the worm gear is passed through the box, and both ends of the worm gear extend out of the box;

[0007] Two clamping plates are arranged at intervals on one side of the turntable opposite to the box body. The two clamping plates are both arc-shaped and have openings facing each other. Locking pieces are arranged on one end of the two clamping plates away from the turntable.

[0008] As a further optimization of the above technical solution, rotating blocks are installed at both ends of the worm.

[0009] As a further optimization of the above technical solution, the locking parts are a locking bolt and a locking nut, and a through hole is provided at one end of the two clamping plates away from the turntable.

[0010] As a further optimization of the above technical solution, a locking plate is provided at one end of the two clamping plates away from the turntable, and the through hole is opened on the locking plate.

[0011] As a further optimization of the above technical solution, anti-slip pads are provided on opposite sides of the two splints.

[0012] As a further optimization of the above technical solution, the anti-slip pad is made of rubber.

[0013] As a further optimization of the above technical solution, a cavity is opened in the turntable, and a synchronization component capable of controlling the two arc-shaped splints to move closer or farther away is arranged in the cavity.

[0014] As a further optimization of the above technical solution, the synchronization component includes a rotating rod rotatably arranged in the cavity and perpendicular to the top wall and bottom wall of the cavity, and a moving rod slidably passed through the side wall of the cavity. A gear is provided on the rotating rod. There are two moving rods arranged in parallel, and the two moving rods are symmetrical along the center of the rotating rod. The opposite sides of the two moving rods are provided with racks that mesh with the gears. A connecting plate is provided at one end of each moving rod located outside the turntable, and a connecting rod is fixed between the connecting plate and the corresponding splint.

[0015] As a further optimization of the above technical solution, one end of each moving rod located in the cavity is connected to a limiting slider, and a limiting sliding groove corresponding to the limiting slider is opened in the cavity.

[0016] As a further optimization of the above technical solution, the front wall of the box body can be detachably mounted on the box body.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] The utility model drives the turntable to rotate by the worm and the worm gear, and the turntable drives the two clamping plates thereon to rotate, thereby adjusting the clamping angles of the two clamping plates, facilitating the installation of the box body, and ensuring that the angle of the dual-axis inclination sensor is downward.

[0019] After the dual-axis inclination sensor of the utility model is installed on the distribution network tower, when the angle of the dual-axis inclination sensor body tilts, the worm is rotated. Since the angle of the clamping plate clamped on the distribution network tower is fixed at this time, the angle of the box and the dual-axis inclination sensor body inside it will change, thereby realizing the angle adjustment of the dual-axis inclination sensor body and improving the installation accuracy.

[0020] The utility model controls the relative movement of two clamping plates by arranging a synchronization component in the cavity of the turntable. The dual-axis tilt sensor can be installed at positions of different diameters on the distribution network tower, and has strong adaptability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The technical solution of the present invention is further elaborated in detail below with reference to specific embodiments. Parts not described or disclosed in detail in the following embodiments of the present invention should be understood as existing technologies known or should be known to those skilled in the art, such as the structure and operation method of the dual-axis inclination sensor body.

[0027] Example 1

[0028] like Figure 1 、 2 As shown in Figures 3 and 4, the present invention discloses a dual-axis tilt sensor suitable for monitoring the inclination of distribution network towers, comprising a housing 1 and a dual-axis tilt sensor body 2 disposed within the housing 1. The housing 1 has a rectangular shape, comprising a front wall, a rear wall, and side walls connected between the front and rear walls. The front and rear walls are both square, and the four side walls are all rectangular. The dual-axis tilt sensor body 2 is fixed to one of the side walls of the housing 1. An inspection port is provided on the front side of the housing 1, and a sealing plate 3 is connected to the inspection port by bolts. The sealing plate 3 is the front wall of the housing 1.

[0029] A rotating shaft 4 is installed on the box body 1. One end of the rotating shaft 4 is located in the box body 1 and is rotatably installed on the inner side of the front wall of the box body 1. The other end passes through the rear wall of the box body 1 and is fixed with a turntable 5. A worm gear 6 is sleeved on the rotating shaft 4 located in the box body 1. A worm 7 adapted to the worm gear 6 is passed through the box body 1. The worm 7 is rotatably set on the side wall of the box body 1 and both ends of the worm 7 pass through the side wall of the box body 1 and extend out of the box body 1.

[0030] The turntable 5 is a circular plate with a diameter smaller than the side length of the rear wall of the housing 1. The plane of the turntable 5 is perpendicular to the axis of the rotating shaft 4. Two clamping plates 8 are provided on the side of the turntable 5 facing away from the housing 1. These clamping plates 8 are perpendicular to the plate surface of the turntable 5. The clamping plates 8 are curved, with their openings facing each other. They are used to clamp the target position on the distribution network tower to secure the dual-axis tilt sensor to the distribution network tower.

[0031] The ends of the two curved clamping plates 8 away from the turntable 5 are provided with locking members. The locking members are locking bolts 11 and locking nuts 12. Through holes are formed on the ends of the two curved clamping plates 8 away from the turntable 5. After the locking bolts 11 are sequentially passed through the through holes of the two curved clamping plates 8, the locking nuts 12 are installed on the locking bolts 11, thereby locking the two curved clamping plates 8.

[0032] Furthermore, a locking plate 10 is provided at one end of the two arc-shaped clamping plates 8 away from the turntable 5, and the through hole is opened on the locking plate 10. The locking plate 10 is a rectangular flat plate. The locking plates 10 on the two arc-shaped clamping plates 8 are parallel, and the plane where the locking plates 10 are located is perpendicular to the plane where the turntable 5 is located.

[0033] Anti-skid pads are provided on opposite sides of the two arc-shaped splints 8 , and the specific material of the anti-skid pads is rubber, which can conveniently increase the anti-skid performance of the arc-shaped splints 8 .

[0034] Both ends of the worm 7 pass through the side walls of the box body 1 and are connected to the rotating block 13. By rotating the rotating block 13, the worm 7 can be easily driven to rotate.

[0035] When the clamping angle of the arc-shaped clamping plate 8 needs to be adjusted, the rotating block 13 is rotated to rotate the worm 7, the worm 7 drives the worm wheel 6 to rotate, the worm wheel 6 drives the rotating shaft 4 to rotate, the rotating shaft 4 drives the turntable 5 to rotate, and the turntable 5 drives the two clamping plates 8 thereon to rotate, thereby adjusting the clamping angle of the two clamping plates 8 so that the angle of the dual-axis inclination sensor body 2 is downward. The utility model can conveniently adjust the clamping angle of the two clamping plates 8, thereby facilitating the installation of the box body 1.

[0036] Example 2

[0037] The overall structure of this embodiment is the same as that of embodiment 1, except that, in this embodiment, a cavity is provided in the turntable 5 , and a synchronization component 9 capable of controlling the two clamping plates 8 to move closer or further away is provided in the cavity.

[0038] Specifically, such as Figure 4 As shown, the cavity is long and narrow, and is surrounded by a turntable front wall, a turntable rear wall and turntable side walls connected between the turntable front wall and the turntable rear wall. For ease of understanding, the turntable front wall is set as the panel surface of the turntable 5 close to the box body 1, and the turntable rear wall is set as the panel surface of the turntable 5 facing away from the box body 1.

[0039] The synchronization component 9 includes a rotating rod 91 rotatably arranged in the cavity and a moving rod 93 slidably penetrated through the side wall of the turntable. The rotating rod 91 is horizontally arranged in the cavity and perpendicular to the front wall and the rear wall of the turntable, and a gear 92 is sleeved on the rotating rod 91. There are two moving rods 93, and the two moving rods 93 are respectively located on the upper and lower sides of the gear 92 and are arranged horizontally. The two moving rods 93 are symmetrically arranged along the center of the rotating shaft 4. The opposite sides of the two moving rods 93 are connected to racks 94, and the two racks 94 are engaged with the gear 92. Through holes corresponding to the moving rods 93 are opened on the left and right sides of the turntable 5.

[0040] Combine Figure 2 、 3 As shown, a connecting plate 95 is provided at one end of each moving rod 93 located outside the turntable 5, and a connecting rod 96 is fixed between the connecting plate 95 and the corresponding clamping plate 8. The connecting plate 95 is vertically fixed to the end of the moving rod 93, and the moving rod 93 and the connecting rod 96 are parallel to each other. One end of the moving rod 93 is vertically fixed to the plate surface of the connecting plate 95, and the other end is fixed to the side wall of the clamping plate 8 close to the connecting plate 95. When one of the clamping plates 8 is pulled, the clamping plate 8 pulls the connecting rod 96, the connecting rod 96 pulls the connecting plate 95, the connecting plate 95 pulls the moving rod 93, and the moving rod 93 pulls the rack 94, thereby driving the gear 92 to rotate. When the gear 92 rotates, it shifts the other rack 94, thereby using the other rack 94 to drive the other clamping plate 8 to move, so that the two clamping plates 8 move away from or closer to each other, so that the two clamping plates 8 can move synchronously, and the stability of the installation of the box body 1 can be maintained.

[0041] The side wall of the moving rod 93 is connected to the limiting slider 14, and the upper and lower sides of the cavity are provided with limiting grooves corresponding to the limiting slider 14. The limiting groove is long and consistent with the length direction of the cavity. The moving rod 93 pulls the limiting slider 14, so that the limiting slider 14 slides in the limiting groove, which can facilitate the limiting of the moving rod 93.

[0042] When this embodiment is in use, the worm 7 is rotated, the worm 7 drives the worm wheel 6 to rotate, the worm wheel 6 drives the rotating shaft 4 to rotate, the rotating shaft 4 drives the turntable 5 to rotate, and the turntable 5 drives the two clamping plates 8 on its side walls to rotate, thereby adjusting the clamping angle of the two clamping plates 8 so that the angle of the inclination sensor body is downward.

[0043] When fixing the dual-axis tilt sensor of the present invention on the distribution network tower, first, when one of the clamping plates 8 is pulled, the clamping plate 8 pulls the connecting rod 96, the connecting rod 96 pulls the connecting plate 95, the connecting plate 95 pulls the moving rod 93, and the moving rod 93 pulls the rack 94, thereby driving the gear 92 to rotate. When the gear 92 rotates, it shifts the other rack 94, thereby using the other rack 94 to drive the other clamping plate 8 to move, so that the two clamping plates 8 move away from or approach each other, so that the two clamping plates 8 can move synchronously and clamp the clamping plates 8 at the target position of the distribution network tower; then, the locking bolt 11 is passed through the two locking plates 10 and locked with the locking nut 12, thereby completing the installation of the dual-axis tilt sensor.

[0044] On the one hand, the present invention adjusts the clamping angle of the two clamping plates 8 so that the angle of the inclination sensor body is always kept downward, which can facilitate the adjustment of the clamping angle of the two clamping plates 8, thereby facilitating the installation of the box 1; on the other hand, after the dual-axis inclination sensor is installed on the distribution network tower, when the angle of the dual-axis inclination sensor body 2 tilts, the worm 7 is rotated, and the clamping angle of the clamping plates 8 clamped on the distribution network tower is fixed. Therefore, the angle of the box 1 and the dual-axis inclination sensor body 2 therein will change, thereby realizing the angle adjustment of the dual-axis inclination sensor body 2 and improving the installation accuracy.

[0045] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
