Description
Technical Field
The invention relates to the field of laying of power grid poles, in particular to an intelligent repairing system for a power transmission tower in a frozen soil area.
Background
The electric power engineering is one of important civil engineering in China, and plays a significant role in the national development process. Power delivery is an important link between the power plant and the residential power. At present, the electric power transmission mainly comprises cable transmission, including submarine cables, underground cables, surface pole tower cables and the like. In the transmission of a tower cable, the stability of a tower structure and the stability of a tower foundation are important to the safety of power transmission. The pole tower structure is well solved through the manners of hinging the reinforced concrete column pole tower and the steel frame.
The stability of the pole tower foundation is limited by various complicated geological conditions along with the extension of the power transmission line, including the construction of the pole tower foundation in the mountain canyon area, the construction of the pole tower foundation in the frozen soil area, the construction of the pole tower foundation in the desert and the like. The problems encountered in the construction of the tower foundation in the frozen soil area are more, and after the construction of the tower foundation in the seasonal frozen soil area, the tower foundation is seriously deformed due to repeated freezing and thawing actions, so that the upper power transmission concrete line pole is inclined at a large angle and even topples over. The safety of power transmission in northeast China, xinjiang and Qinghai-Tibet China is seriously threatened. In the current seasonal frozen soil area, the power transmission pole is mainly directly buried in the soil layer, only a few simple treatments are carried out, the thickness of the seasonal frozen soil layer is often larger than the buried depth of the power transmission pole, and the influence caused by the freezing and thawing circulation effect is larger.
The currently used treatment measures are mainly of two types: 1. the two power transmission poles are buried in soil in a mode that the tops of the two power transmission poles are overlapped at a certain angle and the bottoms of the two power transmission poles are opened at a certain angle, so that the influence of freezing and thawing actions on the power transmission poles is eliminated; 2. after a single wire pole is buried in the soil, a concrete abutment is arranged at the bottom of the power transmission pole or a soil pile with a certain height is arranged on the ground surface so as to eliminate the influence of the freeze thawing action on the stability of the power transmission pole. The method comprises the steps that the tops of two transmission lines are overlapped and the bottoms of the two transmission lines are opened at a certain angle and are buried in the soil to eliminate the influence of freezing and thawing, the influence of freezing and thawing is relieved by changing the structural form of the transmission lines, but the two transmission lines are buried in seasonal frozen soil layers, and the seasonal freezing and thawing effect can cause the whole deformation of the two transmission lines, so that the whole system is inclined or even toppled; in addition, when deformation between two power transmission poles is larger in variability under the influence of freeze thawing, the phenomenon of power transmission pole breakage easily occurs, and the generated harm is larger.
In another method for eliminating the freeze thawing effect by piling soil on the ground surface of a single power transmission line rod or arranging a concrete pier at the root of the line rod, the piling soil is positioned at the upper part of a seasonal frozen soil layer, the direct effect and the indirect effect of freeze thawing affect the strength of the piling soil body, and after the strength is deteriorated, the stability of the line rod is affected. The method for arranging the concrete abutment at the bottom of the power transmission pole is characterized in that the whole structure is positioned in a seasonal frozen soil layer, the frozen soil layer is easy to generate integral large deformation under the repeated actions of freezing and ablation processes, and the temperature greatly fluctuates, so that the temperature difference between the temperature in the concrete structure body and the temperature of the surrounding frozen soil layer is increased, the mutual heat exchange between the concrete structure and the surrounding soil body is increased, the damage process of the concrete structure is accelerated, and the stability of the power transmission pole in the later stage is influenced.

Detailed Description
The technical scheme of the invention is further described below by specific embodiments with reference to the accompanying drawings:
example 1
As shown in fig. 1, the intelligent level 6 in the figure mainly performs intelligent conversion on the inclination of the pole according to the following principle: after the level is inclined, the position of an air bubble in the level is changed, the bottom laser displacement tracker converts the angle of the line rod offset according to the tracking result, and the intelligent level can calculate the angle of the line rod according to y=ax+b, wherein a and b are calculation coefficients, y is the inclination angle, x is the level offset. After conversion, the data are transmitted to the first anchoring automatic deviation correcting machine system 8, the second anchoring automatic deviation correcting machine system 9 and the third anchoring automatic deviation correcting machine system 10 through the intelligent acquisition controller 7. The first anchoring automatic deviation rectifying machine system 8, the second anchoring automatic deviation rectifying machine system 9 and the third anchoring automatic deviation rectifying machine system 10 rectify, and the triangle system is utilized for rectifying, and the rectification principle is as follows: after the wire rod is inclined, the stretching of part of the triangle side in the triangle balancing system at the bottom is increased sharply, the tension of the part of the triangle side is reduced sharply, the three triangle sides are in a balanced state at the beginning, have own tension values respectively, and move the deviation correcting machine system respectively to carry out force balance deviation correction according to the force balance principle, and mutually verify the angles calculated by the intelligent level to achieve the complete wire rod deviation correction. And the communication between the moment and the intelligent acquisition controller 7 is kept during the correction until the data of the intelligent level gauge 6 is recovered to be normal. Normal standard value: the two base angles of the triangle are equal. When the balance is broken, the whole repair system starts to be started. The solar cell panel 3 mainly provides power for the respective movable deviation correcting machine system and the intelligent acquisition controller 7, a wireless transmission antenna is arranged in the intelligent acquisition controller 7, even if adjusting information is transmitted to an indoor computer terminal, an engineering person can judge the operation condition of the power transmission pole through the information acquired by the computer terminal, meanwhile, the operation state of the intelligent deviation correcting system is known, and the problem can be solved in time after the fault occurs. The bottom weight compartment 5 is filled with high density concrete, the total weight of which is greater than the weight of the wire pole. In the work of the intelligent deviation correcting system, the bottom can keep rotating and sliding, and then the phenomenon of breakage caused by overlarge adjustment amplitude of the power transmission pole 1 can be avoided.
The first anchoring automatic deviation rectifying machine system 8, the second anchoring automatic deviation rectifying machine system 9 and the third anchoring automatic deviation rectifying machine system 10 have the same structure, and are composed of a deviation rectifying system inner bin 12, an anchoring adjusting frame 13, an adapter 14 and an intelligent steering system 15 as shown in fig. 3. The whole anchoring automatic deviation correcting machine system is anchored through the bottom anchoring adjusting frame 13 and the multi-year frozen soil layer 22, so that the phenomenon that the deviation correcting effect of the power transmission line pole is influenced due to position movement generated by the automatic deviation correcting machine system in the working process of the deviation correcting machine is avoided. A correction steel bar selection system 16 and an automatic correction machine control system 18 are arranged in the bin 12 in the correction system, the correction steel bar selection system 16 identifies corresponding correction steel bars by using a steel bar intelligent identifier 17, and an intelligent calculation balancer 19 is arranged in the automatic correction machine control system 18. The top intelligent steering system 15 can rotate properly according to the adjustment requirement and work in cooperation with a deviation rectifying machine. The automatic deviation correcting machine control system 18 mainly receives the transmission line pole inclination data collected by the intelligent level 6 transmitted by the intelligent collection controller 7. The intelligent level 6 mainly collects the inclination angle value of the wire rod and the tension value F of each side collected by the bottom triangle system, and performs deviation correcting operation according to the data. The specific deviation correcting quantity is converted by identifying the data, the specific deviation correcting sequence is determined, the deviation correcting reinforcing steel bars are determined, the data are transmitted to the intelligent computing balancer 19, the intelligent computing balancer 19 continuously transmits the data to the reinforcing steel bar intelligent identifier 17 after computing and analyzing, the identifier determines the specific deviation correcting reinforcing steel bars between adjacent triangles, then the repairing system starts to work, the data are transmitted to the intelligent acquisition controller 7 in real time through the data wire for identification in the deviation correcting process, and the system stops after the deviation correcting work is finished, so that the balance state is maintained.
The specific operation steps are as follows: 1. once the power transmission pole is disturbed by the freeze-thawing cycle action of the frozen soil in the seasonal frozen soil layer to incline, the intelligent repair system is started. The intelligent level gauge transmits the collected data such as the inclination angle and the like to the intelligent collection controller.
2. After the intelligent acquisition controller analyzes the data, the data are transmitted to the respective dynamic deviation rectifying machine system, the system determines the deviation rectifying quantity and the specific order of deviation rectifying in the specific balance system after analyzing the data, and then the deviation rectifying work is started.
3. In the correction work, the respective movable correction machine system is communicated with the intelligent acquisition control system all the time until the correction work is finished. In the process, the intelligent acquisition controller sends data to the computer terminal of the electric department through the wireless transmitter for analysis and viewing by engineers.
4. After the correction work is finished, the system keeps self-balance. The three triangles keep self balance at all times and have good balance among each other, and the bottom degree of freedom in the wire pole adjustment is guaranteed to wire pole bottom counter weight, but does not lead to the wire pole to topple over again because of great weight.
