Description

Technical Field

[0001] The present invention relates to the technical field of power grid line construction, and in particular to a wire pole status monitoring framework for three-dimensional point cloud space measurement of power grid line construction. Background Art

[0002] A 3D point cloud is a data set consisting of a large number of discrete points in a 3D coordinate system. These points are usually obtained by obtaining geometric information on the surface of an object through technologies such as laser scanning and photogrammetry. In the construction of power grid lines, 3D point cloud spatial measurement uses these technologies to obtain 3D spatial information of power grid line-related facilities, such as poles or wires, including their location, shape, size, etc.

[0003] Some management and supervision use three-dimensional point cloud simulation to carry out spatial modeling and measurement. However, it is difficult to obtain local structural dynamics in a timely and accurate manner for construction difficulties in the actual line construction process, such as tower tilt detection and cross-span construction, which in turn affects the stability of quantitative and detailed analysis and supervision processes.

[0004] In actual power grid line construction scenarios, there are some problems with spatial measurement using existing three-dimensional point cloud simulation monitoring architectures. First, in terms of monitoring accuracy, existing monitoring architectures often cannot accurately monitor the tilt direction and severity of the poles. This is because existing sensors are affected by environmental factors such as temperature, humidity, wind, etc., resulting in inaccurate monitoring data. In addition, the existing monitoring architecture cannot detect slight tilt changes in the poles in a timely manner, and thus cannot effectively prevent the occurrence of pole tilt accidents. Secondly, in terms of installation and maintenance, the existing monitoring architecture requires a complex installation process and professional technicians, which increases the cost and difficulty of installation and maintenance. Therefore, the present invention provides a three-dimensional point cloud spatial measurement of the pole status monitoring architecture for power grid line construction to address the deficiencies in the prior art.

[0014] The present invention provides a three-dimensional point cloud spatial measurement of the pole status monitoring framework for power grid line construction.

It is faster and more intuitive than the traditional three-dimensional point cloud camera acquisition. In the main detection mechanism, the reduction motor drives the cylindrical gear to drive the gear ring to rotate, so that the three balls can roll along the outside of the wire pole. When the wire pole is offset, the balls will produce different pressures on the wire pole according to the inclination of the wire pole. This pressure is transmitted to the sliding rod through the rotating block, and then to the pressure sensor 2. As the three sliding rods rotate continuously, the inclination direction of the wire pole can be accurately determined. At the same time, the arc plate in the secondary detection mechanism is in contact with the outside of the wire pole. When the wire pole is seriously tilted, the arc plate will be squeezed, and the arc plate will transmit the pressure to the spring telescopic rod, and the spring telescopic rod will transmit the pressure to the pressure sensor 1, so that the severity of the inclination of the wire pole can be confirmed. This all-round monitoring method can timely detect the slight inclination changes of the wire pole, providing a strong guarantee for the safety of power grid line construction.

[0015] 2. The present invention uses the platform as the basis of the entire monitoring structure. The four groups of positioning columns on the top of the platform and the assembly plate of the secondary detection mechanism are designed with positioning holes, blocks and slots, so that the assembly plate can be quickly and accurately installed on the positioning columns, and is firmly fixed on the positioning columns under the action of the blocks and torsion springs to prevent it from loosening or displacement during use.

[0020] Specifically, it includes a platform 1 and a pole 2.

Four groups of positioning columns 3 are fixedly connected to the top of the platform 1, and the number of each group of positioning columns 3 is two.

A ball 24 is slidably connected to one side of the rotating block 23, and the outer side of the ball 24 contacts the outer side of the wire rod 2.

The two ends of the reset spring 27 are respectively fixedly connected to the outer side of the fixed cylinder 25 and one end of the sliding rod 26.

[0022] Specifically, a main detection mechanism is provided on the top of the platform 1, and the main detection mechanism includes a driving component and three measuring components. The driving component includes a reduction motor 18 and a support plate 12. The reduction motor 18 is installed on the outside of the platform 1. The reduction motor 18 usually uses a motor with high precision and high torque to ensure that the gear ring 15 can be stably driven to rotate. The output end of the reduction motor 18 is fixedly connected with a cylindrical gear 19, and the cylindrical gear 19 is meshed with the gear ring 15. Through the drive of the reduction motor 18, the cylindrical gear 19 drives the gear ring 15 to rotate. The support plate 12 is sleeved on the outside of the wire rod 2, and the outer sleeve of the wire rod 2 is provided with a gear ring 15, and the gear ring 15 is located directly above the support plate 12. The support plate 12 is usually made of metal material and has certain strength and stability. Eight plug rods 14 are fixedly connected to the bottom of the support plate 12, and a socket 28 is opened on the top of the positioning column 3, and the bottom end of the plug rod 14 is engaged in the inside of the socket 28. This design enables the support plate 12 to be firmly mounted on the platform 1, providing stable support for the rotation of the gear ring 15. A track groove 13 is provided on the top of the support plate 12, and the track groove 13 is annular. Two limit grooves are provided on the inner wall of the track groove 13, and two movable rods 16 are fixedly connected to the bottom of the gear ring 15, and the two movable rods 16 are symmetrical about the center of the gear ring 15. The bottom end of the movable rod 16 is fixedly connected to a limit rod 17, and the outer side of the movable rod 16 is slidably connected to the inner side of the track groove 13, and the outer side of the limit rod 17 is slidably connected to the inner wall of the limit groove. This design enables the gear ring 15 to remain stable during the rotation process to avoid displacement or shaking. The measuring assembly includes a mounting seat 1 20 and a mounting seat 2 22, and the bottoms of the mounting seat 1 20 and the mounting seat 2 22 are fixedly connected to the top of the gear ring 15. The mounting seat 1 20 and the mounting seat 2 22 are usually made of metal materials and have certain strength and stability. A pressure sensor 21 is installed on the outer side of the mounting seat 1 20, and the pressure sensor 21 can monitor the pressure change of the wire rod 2 to the wire rod 2 status monitoring structure in real time. A rotating block 23 is rotatably connected to the inner side of the mounting seat 22, and a torsion spring is sleeved at the rotating shaft. Under the action of the torsion spring, the rotating block 23 makes the ball 24 close to the outer wall of the wire rod 2. When the wire rod 2 tilts, the ball 24 will roll with the tilt of the wire rod 2, thereby driving the rotating block 23 to rotate. The ball 24 is slidably connected to one side of the rotating block 23, and the outer side of the ball 24 contacts the outer side of the wire rod 2. The ball 24 is usually made of hard material, such as a steel ball or a ceramic ball, which can reduce friction and wear during rolling. The outer side of the rotating block 23 is fixedly connected to a fixed cylinder 25, and the interior of the fixed cylinder 25 is slidably connected to a sliding rod 26, and one end of the sliding rod 26 contacts the outer side of the pressure sensor 21. When the wire rod 2 tilts, the ball 24 generates pressure on the wire rod 2, and the pressure is transmitted to the sliding rod 26 through the rotating block 23, and the sliding rod 26 transmits the pressure to the second pressure sensor 21. The second pressure sensor 21 can determine the tilt direction and degree of the wire rod 2 according to the received pressure changes.The sliding rod 26 is sleeved with a return spring 27, and the two ends of the return spring 27 are respectively fixedly connected to the outer side of the fixing tube 25 and one end of the sliding rod 26. The return spring 27 can help the sliding rod 26 to reset after being pressed, ensuring that the pressure sensor 21 can accurately monitor the pressure change of the wire rod 2.

[0023] Working principle: the gear ring 15 and the support plate 12 are sleeved on the outer circumference of the wire rod 2 before the wire rod 2 is installed, and the platform 1 is built based on the installation center of the wire rod 2 to ensure the accuracy of the primary and secondary detection mechanisms installed at the back. The rotating block 23, under the action of the torsion spring, makes the ball 24 close to the outer wall of the wire rod 2, and the reduction motor 18 is started to drive the cylindrical gear 19 to drive the gear ring 15 to rotate. The cooperation between the movable rod 16, the limit rod 17, the track groove 13 and the limit groove makes the gear ring 15 rotate stably, so that the three balls 24 will roll along the outer side of the wire rod 2. When the wire rod 2 is offset, the pressure transmitted to the pressure sensor 21 by the three sliding rods 26 will change. When the sliding rod 26 rotates continuously and the ball 24 is pressed down on the wire rod 2, the pressure value detected by the pressure sensor 21 near the ball 24 will be increased to the maximum. When there is a pressure sensor 21 on the opposite side of the tilt, the detected pressure value will be reduced to the minimum. In this way, the tilt direction of the wire rod 2 can be determined. In addition, when the wire rod 2 is seriously tilted, the arc plate 8 will be squeezed, and then the spring telescopic rod 7 will transfer the pressure to the pressure sensor 9. In this way, it can be confirmed that the wire rod 2 is seriously tilted, and the data obtained by the pressure sensor 9 and the pressure sensor 21 can be sent to the external device in real time, which is more convenient and intuitive than the traditional three-dimensional point cloud camera acquisition.
