[0020] The present invention also provides an anti-deformation monitoring method of a deformation monitoring system, comprising the following steps:

[0021] Step 1, installing a plurality of high-voltage line towers (4) in the monitoring area; each of the high-voltage line towers (4) is equipped with a high-voltage line tower anti-deformation device, a motor control mainboard, a level detection sensor (7), an electromagnetic wave ranging monitoring module (8) and an information transmission module (9);

[0026] At the same time, each high-voltage line tower (4) transmits electromagnetic waves to other n-1 high-voltage line towers (4) at a periodic basis through the high-voltage line tower electromagnetic transmitting unit; therefore, the high-voltage line tower (4) receives electromagnetic waves from other n-1 high-voltage line towers (4) through the high-voltage line tower electromagnetic receiving unit, and simultaneously receives electromagnetic waves from the surface signal transmitting device (10);

[0027] Therefore, for each high-voltage line tower (4), in each monitoring period, the distance values ​​of the other n-1 high-voltage line towers (4) relative to itself are calculated, and the distance value of each surface monitoring point relative to itself is calculated;

[0048] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0049] In order to realize automatic adjustment of high-voltage transmission tower deformation, avoid tower tilt and even damage to power facilities caused by surface deformation or other uncertain factors, realize monitoring of key areas, and meet the needs of deformation monitoring, automatic adjustment and early warning, the present invention uses horizontal detection sensors, adjustment and leveling modules and wireless transmission technology to design and manufacture a high-voltage tower anti-deformation device and surrounding area deformation monitoring system. It can greatly reduce labor intensity and realize automatic monitoring of key areas.

[0050] The present invention provides a high-voltage line tower anti-deformation device, referring to Figure 1 , including: a high-voltage tower base 1, a mounting base 2 and an adjustment and leveling module 3;

[0051] refer to Figure 2 A plurality of mounting foundations 2 are fixedly installed on the top of the high-voltage tower base 1; the mounting foundation 2 is cast by concrete at one time; threaded holes are processed on the mounting foundation, and the position and size of the threaded holes are consistent with the connecting screws.

[0052] The number of installation bases 2 is the same as the number of tower feet of the high-voltage line tower 4; each installation base 2 is correspondingly installed with an adjustment and leveling module 3; usually, the high-voltage line tower 4 has four tower feet, so four installation bases 2 need to be installed. The top of each installation base 2 is connected to a corresponding tower foot through the adjustment and leveling module 3.

[0053] Among them, reference Figure 3 and Figure 4 , each adjustment and leveling module 3 includes an upper connecting plate 3-1, a lower connecting plate 3-2, a connecting column 3-3, a connecting ball 3-4, a connecting screw 3-5, a bidirectional motor 3-6 and a gear 3-7;

[0054] The upper connecting plate 3-1 and the lower connecting plate 3-2 are arranged opposite to each other in the upper and lower directions; the four corners of the upper connecting plate 3-1 are connected to the four corners of the lower connecting plate 3-2 through a connecting column 3-3, thereby connecting the upper connecting plate 3-1 and the lower connecting plate 3-2 to form a whole; wherein the connecting column 3-3 includes a connecting column body 3-3-1, the upper end of the connecting column body 3-3-1 forms a spherical upper end head 3-3-2, the lower end of the connecting column body 3-3-1 forms a spherical lower end head 3-3-3, the spherical upper end head 3-3-2 is embedded in the corresponding spherical groove of the upper connecting plate 3-1; the spherical lower end head 3-3-3 is embedded in the corresponding spherical groove of the lower connecting plate 3-2; the upper surface of the lower connecting plate 3-2 forms the first A hemispherical groove 3-2-1 is formed, and a second hemispherical groove is symmetrically formed on the lower surface of the upper connecting plate 3-1; the diameters of the first hemispherical groove 3-2-1 and the second hemispherical groove are larger than the diameter of the connecting ball 3-4, and the connecting ball 3-4 is clamped in the first hemispherical groove 3-2-1 and the second hemispherical groove, and the upper connecting plate 3-1 is slightly moved relative to the lower connecting plate 3-2; the upper connecting plate 3-1 is fixedly connected to a tower foot of the high-voltage line tower 4; the connection method between the upper connecting plate 3-1 and the lower connecting plate 3-2 through the connecting column 3-3 and the connecting ball 3-4 is essentially a flexible connection method, which reduces the rigid force on the tower during the adjustment process and avoids damage to the structure of the tower body itself.

[0055] The installation base 2 is provided with four threaded holes 2-1; each threaded hole 2-1 is correspondingly installed with a connecting screw 3-5; wherein the bottom of each connecting screw 3-5 is threadedly connected with the threaded hole 2-1; the top of each connecting screw 3-5 is rotatably connected with the corresponding position of the lower connecting plate 3-2 through a bearing;

[0056] A gear 3-7 is installed at the center of the four connecting screws 3-5. The gear 3-7 is meshed with each connecting screw 3-5 at the same time. The gear 3-7 is fixed to the output shaft of the bidirectional motor 3-6. The bidirectional motor 3-6 is fixedly installed in the mounting hole at the center position of the mounting base 2; under the drive of the bidirectional motor 3-6, the gear 3-7 is driven to rotate forward or reverse. When the gear 3-7 rotates, it drives each connecting screw 3-5 to perform lifting and lowering movements.

[0057] In this application, the motor control main board and the bidirectional motor are packaged and protected to prevent rust and moisture, thereby ensuring the flexibility of the mechanical mechanism during the adjustment process.

[0058] In practical applications, such as Figure 6As shown, the connecting screw 3-5 includes a connecting screw body 3-5-1, and the surface of the connecting screw body 3-5-1 has a plurality of long strip protrusions 3-5-2 arranged at equal intervals, and the intervals between adjacent long strip protrusions 3-5-2 match the teeth of the gear 3-7; therefore, the connecting screw 3-5 can be driven to rotate under the drive of the gear 3-7. In addition, since the surface of each long strip protrusion 3-5-2 has an external thread 3-5-3 matching the threaded hole 2-1, the connecting screw 3-5 is threadedly connected to the threaded hole 2-1, so when the connecting screw 3-5 rotates, it will move up and down around the threaded hole.

[0059] The hard spring 5 is also included; the hard spring 5 is sleeved on the outside of each connecting screw 3-5, one end of the hard spring 5 is against the upper surface of the installation base 2, and the other end of the hard spring 5 is against the lower surface of the lower connecting plate 3-2. By installing the hard spring 5, the force of the connecting screw 3-5 to perform lifting and lowering movement under the drive of the bidirectional motor 3-6 can be alleviated, so that the connecting screw 3-5 can move slowly and avoid damage to the tower body structure itself.

[0060] The present invention also provides a deformation monitoring system based on the high-voltage tower anti-deformation device, comprising the high-voltage tower anti-deformation device, a motor control mainboard, a level detection sensor 7, an electromagnetic wave ranging monitoring module 8, an information transmission module 9, a surface signal transmitting device 10 and a general control center;

[0061] The middle part of each high-voltage line tower 4 is at the same horizontal plane, and a plurality of level detection sensors 7 are installed; each level detection sensor 7 is perpendicular to each other; by analyzing each level detection sensor 7, it can be determined whether the high-voltage line tower 4 is tilted.

[0062] An electromagnetic wave ranging monitoring module 8 and an information transmission module 9 are installed on the top of each high-voltage line tower 4; the bidirectional motors 3-6 are connected to the motor control mainboard;

[0063] refer to Figure 7 , installing a plurality of surface signal transmitting devices 10 on the ground of the monitoring area;

[0064] The level detection sensor 7 , the electromagnetic wave ranging monitoring module 8 and the motor control main board are all connected to the main control center signal through the information transmission module 9 .

[0065] The anti-deformation monitoring method of the above deformation monitoring system comprises the following steps:

[0066] Step 1, multiple high-voltage line towers 4 are installed in the monitoring area; each high-voltage line tower 4 is equipped with a high-voltage line tower anti-deformation device, a motor control mainboard, a level detection sensor 7, an electromagnetic wave ranging monitoring module 8 and an information transmission module 9;

[0067] Select a number of surface monitoring points on the surface of the monitoring area, and install a surface signal transmitting device 10 at each surface monitoring point;

[0068] During actual installation, a location that is convenient for signal transmission and reception is selected for installation. Among them, the surface monitoring point is installed with a surface signal transmitting device 10 that only has a signal transmission function; while the electromagnetic wave ranging monitoring module 8 installed on the high-voltage line tower 4 has signal transmission function, signal receiving function and signal analysis function at the same time.

[0069] The information transmission module 9 is installed on the top of the high-voltage tower 4, which is convenient for monitoring data transmission and can protect data transmission relatively safely. The present invention uses electric energy for direct control, which is directly used directly from the power line after adopting corresponding voltage transformation measures.

[0070] Step 2, the main control center pre-stores the high-voltage tower standard position information of each high-voltage tower 4 and the surface monitoring point standard position information of each surface monitoring point;

[0071] Step 3, assuming that there are n high-voltage towers 4 in the monitoring area; each electromagnetic wave ranging monitoring module 8 includes a high-voltage tower electromagnetic transmitting unit, a high-voltage tower electromagnetic receiving unit and a high-voltage tower distance calculation module;

[0072] During the monitoring period, the surface signal transmitting device 10 transmits electromagnetic waves to n high-voltage line towers 4 simultaneously in a periodic manner;

[0073] At the same time, each high-voltage line tower 4 transmits electromagnetic waves to other n-1 high-voltage line towers 4 periodically through the high-voltage line tower electromagnetic transmitting unit; therefore, the high-voltage line tower 4 receives electromagnetic waves from other n-1 high-voltage line towers 4 through the high-voltage line tower electromagnetic receiving unit, and simultaneously receives electromagnetic waves from the surface signal transmitting device 10;

[0074] Therefore, for each high-voltage line tower 4, in each monitoring period, the distance values ​​of the other n-1 high-voltage line towers 4 relative to itself are calculated, and the distance value of each surface monitoring point relative to itself is calculated;

[0075] Step 3: In this monitoring period, for the n high-voltage towers 4, select the high-voltage tower that meets the following conditions as the control tower:

[0076] Condition 1: In the first two monitoring cycles, the high-voltage tower has not tilted; the judgment method is: by analyzing the detection data of the horizontal detection sensor 7 of the high-voltage tower, determining whether the high-voltage tower has tilted;

[0077] Condition 2: In the first two monitoring cycles, the high-voltage tower has not deformed; the judgment method is: the high-voltage tower has not started its own bidirectional motor 3-6 for adjustment and leveling;

[0078] Step 4, therefore, in this monitoring period, it is assumed that a total of m control towers are screened out; each control tower calculates the distance values ​​of the other n-1 high-voltage line towers 4 relative to itself, and calculates the distance value of each surface monitoring point relative to itself;

[0079] Then, for the distance values ​​measured by each control tower, the distance intersection method and the least square solution are used to obtain the actual measured position information of each high-voltage tower 4, and the actual measured position information of each surface monitoring point is obtained;

[0080] Step 5, comparing the high-voltage tower standard position information of each high-voltage tower 4 with the high-voltage tower measured position information, if the high-voltage tower measured position information deviates from the high-voltage tower standard position information by more than a threshold value, a conclusion is drawn that the corresponding high-voltage tower 4 is deformed;

[0081] The standard position information of each surface monitoring point is compared with the measured position information of the surface monitoring point. If the measured position information of the surface monitoring point deviates from the standard position information of the surface monitoring point by more than a threshold, it is concluded that the surface monitoring point is deformed.

[0082] Step 6, in the same monitoring cycle, when a conclusion is drawn that a certain high-voltage line tower 4 is deformed, the adjustment and leveling module 3 of the corresponding high-voltage line tower 4 is controlled according to the deformation of the high-voltage line tower 4, so that the high-voltage line tower 4 is adjusted to a non-deformed state by controlling the bidirectional motors 3-6;

[0083] Specifically, assuming that a certain high-voltage line tower 4 is deformed, the four adjustment and leveling modules 3 are controlled according to the specific situation of the deformation, so as to adjust the tower foot height of the high-voltage line tower 4 and increase the height of the tower foot at a lower position, so that the heights of the four tower feet are equal, that is, the effect of adjustment and leveling is achieved, and the high-voltage line tower 4 is prevented from being tilted too much, thereby ensuring the safety of the high-voltage line tower 4.

[0084] Step 7, then enter the next monitoring cycle; thereby achieving the effect of real-time monitoring of the deformation of the high-voltage tower 4 and timely leveling the high-voltage tower 4.

[0085] Step 8, after the monitoring is completed, a comprehensive analysis is performed on the deformation conditions of each surface monitoring point and the deformation conditions of each high-voltage line tower 4 to obtain the influencing factors that cause the deformation of the high-voltage line tower 4.

[0086] In the installation and construction of a certain area's transmission line, the specific process of using this system is as follows:

[0087] 1) After the installation location of the high-voltage tower is determined according to the transmission line design plan, the foundation is excavated. The foundation excavation depth and the size of the tower base foundation are determined according to the design parameters and local geological soil conditions.

[0088] 2) Cast the high-voltage tower base 1 according to the size. When casting the high-voltage tower base 1, cast four mounting foundations 2 at the same time. Make threaded holes 2-1 and assembly holes for installing the bidirectional motor 3-6 on the four mounting foundations 2 according to a certain size. The size and position of the threaded holes 2-1 and the assembly holes for installing the bidirectional motor 3-6 are strictly consistent with the position and size of the connecting screw 3-5 in the adjustment and leveling module 3.

[0089] 3) After the concrete structure solidifies and the pouring of the high-voltage tower base 1 is completed, the processing and installation of the adjustment and leveling module 3 and the transmission tower begins.

[0090] First, according to the installation needs and strength requirements, the connecting screw 3-5, hard spring, motor control main board and bidirectional motor 3-6 need to be installed above the threaded hole 2-1 as designed. After completing this part of the installation, the upper connecting plate 3-1, the lower connecting plate 3-2, the connecting column 3-3 and the connecting ball 3-4 are assembled to form a connecting mechanism, and it is installed on the connecting screw 3-5.

[0091] After the installation of the above components is basically completed, the tower is installed according to the traditional method, and two horizontal detection sensors 7 perpendicular to each other are installed in the middle of the tower, and the electromagnetic wave ranging monitoring module 8 and information transmission module 9 are installed on the top of the tower to complete the installation of single tower monitoring and adjustment.

[0092] The information transmission module 9 is installed on the top of the transmission tower, which is convenient for monitoring data transmission, and has multiple interfaces to facilitate the deployment of other monitoring means or the transmission of related data. The energy supply of this part is directly from the power line, and the power supply system of this system is deployed after adopting corresponding transformation measures, that is, all electrical components are connected together.

[0093] The above is to complete the installation of the deformation monitoring system of a single intelligent high-voltage tower anti-deformation device, and other transmission towers are installed in the same way. And all the surface signal transmitting devices 10 are installed and laid out in the ground area according to certain rules or monitoring requirements to complete the layout of the regional intelligent monitoring network.

[0094] 4) Then, the coordinates of the electromagnetic wave ranging monitoring modules 8 of all tower parts are obtained and stored using the measurement method. The coordinates of all ground monitoring points are obtained using the designed electromagnetic ranging method and distance intersection method to obtain the first phase data. The first phase data is stored and visualized, and a certain data acquisition cycle is set for monitoring, which completes the installation and deployment of this system.

[0095] The high-voltage tower anti-deformation device, deformation monitoring system and anti-deformation method provided by the present invention have the following advantages:

[0096] (1) The adjustment and leveling module is a flexible adjustment structure, which can effectively reduce the rigid force on the tower during the adjustment process and avoid damage to the tower structure itself;

[0097] (2) It can effectively monitor the deformation of high-voltage transmission towers and automatically adjust the deformation of high-voltage towers to keep the high-voltage towers in an undeformed state, avoid the tilt of the towers and even damage to power facilities caused by surface deformation or other uncertain factors, and ensure the safe and reliable operation of the high-voltage towers. The present invention has the advantages of simple and efficient monitoring and reduces the workload of maintenance personnel.

[0098] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be considered as the scope of protection of the present invention.
