Description

Technical Field

[0001] The present invention relates to the technical field of electric power equipment construction, and in particular to a method and a control device for transforming and reinforcing a transmission line tower in a coal mining subsidence area. Background Art

[0002] When a transmission line passes through the mining area, underground mining activities will cause subsidence basins to appear on the surface, and the transmission towers will also experience corresponding deformations such as tilt, stretching and compression as the surface moves.

[0003] In response to this problem, the current conventional treatment methods are mainly determined by the order of approval of mining rights and construction of line towers. If the mining rights are approved first, the power department will install a large plate foundation or an adjustable foundation when designing the line tower to enhance the line tower's ability to resist deformation, so that the line tower can resist the surface movement and deformation caused by underground mining; if the line tower is built first, the coal mining unit needs to take corresponding underground mining measures or transmission line rerouting measures to ensure that the surface line tower movement and deformation during underground mining does not exceed the allowable value. Conventional methods include backfill mining, limited thickness mining, transmission line rerouting or tower foundation reinforcement.

[0004] Backfill mining refers to a mining method that uses backfill materials to fill the goaf while ore is dropped, transported and other operations are carried out. There are mainly gangue filling and paste filling. Limited thickness mining is based on the terrain, hydrogeological conditions and deformation resistance of buildings and structures in the mining area, and determines the thickness of the mineable coal seam based on the protection level required by the building. Both mining methods can reduce the impact of mining on the surface and achieve the purpose of protecting transmission line towers. However, backfill mining requires the construction of a backfill system, which is complex in process and has a high cost of backfill materials. Limited thickness mining will lead to a low recovery rate of coal resources and a large amount of coal resources will be wasted. Both of the above methods achieve the purpose of protecting the line towers at the expense of coal mine benefits.

[0005] Transmission line rerouting refers to re-erecting high-voltage line towers outside the mine field, and moving the entire transmission line within the mine field to outside the mine field; tower base reinforcement refers to installing a cross beam on the tower base within the mine field, and merging the four tower legs of the tower into a whole to improve the tower's ability to resist deformation. The cost of the line rerouting method is relatively high, and the cost of one kilometer of transmission line is usually more than one million; the tower base reinforcement method is relatively low-cost, but the safety risk level of construction under the tower is high, and it is not suitable for large-scale implementation.

[0006] In summary, when the transmission line crosses the mine field, the several methods currently available to ensure the safe operation of the transmission line either waste coal resources or are costly. Therefore, how to avoid the waste of coal resources while reducing construction costs while ensuring the safe operation of the transmission line is an urgent problem to be solved in the industry. Summary of the invention

[0030] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Combine the following Figures 1 to 9The method and control device for transformation and reinforcement of transmission towers in coal mining subsidence areas of the present invention are described in detail. Among them, the execution subject of the method for transformation and reinforcement of transmission towers in coal mining subsidence areas is an electronic device or a server. The electronic device can be other devices such as personal computers (PCs), portable devices, laptops, smart phones, tablet computers, and portable wearable devices; the server can refer to a server, or it can be a server cluster composed of multiple servers, a cloud server, and the like. The present invention does not specifically limit the specific form of the electronic device or server. Furthermore, the method for transformation and reinforcement of transmission towers in coal mining subsidence areas can also be applied to the control device for transformation and reinforcement of transmission towers in coal mining subsidence areas set in electronic devices or servers. The control device for transformation and reinforcement of transmission towers in coal mining subsidence areas is implemented by software, hardware, or a combination of the two. The following takes the execution subject of the method for transformation and reinforcement of transmission towers in coal mining subsidence areas as the control device for transformation and reinforcement of transmission towers in coal mining subsidence areas as an example, and describes the method for transformation and reinforcement of transmission towers in coal mining subsidence areas.

[0032] like Figure 1 and Figure 2 As shown, a specific embodiment of the first aspect of the present invention provides a method for transforming and reinforcing a transmission line tower in a coal mining subsidence area. The method for transforming and reinforcing a transmission line tower in a coal mining subsidence area comprises: S100. Determine a target transmission line tower according to the mining depth / thickness ratio of the transmission line tower.

[0033] Furthermore, the control device determines the target transmission line tower according to the mining depth and thickness ratio of the transmission cable.

[0034] Specifically, the mining depth and thickness ratio of the transmission cable is input into the control device, and the control device determines the transmission line towers with a mining depth and thickness ratio less than 200 as target line towers. For the transmission line towers with a mining depth and thickness ratio not less than 200, it means that these transmission line towers are less affected by mining and do not need to be processed.

[0035] The mining depth and thickness ratio is an indicator that comprehensively reflects the occurrence conditions of the mined coal seam. In the prediction and assessment of geological disaster risks, the mining depth and thickness ratio is often used as an important basis for predicting the risk of ground collapse. The calculation method is to divide the occurrence depth of the coal seam at the location of the tower by the thickness of the coal seam. The mining depth and thickness ratio can be used to quantitatively judge the magnitude of the risk of ground collapse.

[0036] The calculation process of the mining depth and thickness ratio is simple and can be used as a preliminary basis for judging the degree of impact of mining on the line tower. If the mining depth and thickness ratio is greater than 200, it means that the line tower is less affected by mining and no treatment is required. The line tower with a mining depth and thickness less than 200 needs further analysis.

[0037] S400. Determine the deformation type of the target transmission line tower based on the mining subsidence prediction method. The deformation type includes a horizontally deformed over-standard tower and an inclinedly deformed over-standard tower.

[0038] Furthermore, based on the mining subsidence prediction method, the deformation type of the target transmission line tower is determined, including: Based on the mining subsidence prediction method and the surface movement deformation prediction parameters, determine the tilt deformation value and horizontal deformation value of the target transmission line tower; Based on the tilt deformation value and the horizontal deformation value, the deformation type of the target transmission line tower is determined.

[0039] Specifically, the predicted parameters of surface movement deformation are input into the control device, and the control device processes the predicted parameters of surface movement deformation based on the built-in mining subsidence prediction method to determine the tilt deformation value and horizontal deformation value of the target transmission line tower. The control device can then determine the deformation type of the target transmission line tower based on the tilt deformation value and the horizontal deformation value.

[0040] Further, based on the tilt deformation value and the horizontal deformation value, determining the deformation type of the target transmission line tower includes: The deformation of the target transmission line tower is determined based on the tilt deformation value, the horizontal deformation value, and the surface deformation control requirements for the safe operation of the target transmission line tower.

[0041] Specifically, the control device can determine the deformation of the target transmission line tower based on the preset surface deformation control requirements for safe operation of the target transmission line tower, as well as the determined tilt deformation value and horizontal deformation value.

[0042] Furthermore, the surface deformation control requirements for the safe operation of the target transmission line towers include: The permissible inclination value of angle steel towers and straight towers with a height of 50m and above is 0.5%, and the permissible inclination value of angle steel towers and straight towers with a height of less than 50m is 1%; The maximum root opening deviation of 220~330kV tower structure is ±5‰, the maximum root opening deviation of 500kV tower structure is ±2.5‰, and the maximum root opening deviation of 750kV tower structure is ±2.5‰.

[0043] Specifically, the surface deformation control requirements for the safe operation of the target transmission line tower can be preset in the control device.

[0044] Furthermore, the mining subsidence prediction method includes a typical curve method, a profile function method or a probability integral method. Specifically, the control device processes the predicted parameters of the surface movement deformation using the probability integral method, and can determine the tilt deformation value and the horizontal deformation value of the target transmission line tower.

[0045] S500: Determine a transformation and reinforcement strategy corresponding to the target transmission line tower according to the deformation type of the target transmission line tower.

[0046] Specifically, the control device can determine the corresponding transformation and reinforcement strategy of the target transmission line tower according to the deformation type of the target transmission line tower, and output the specific steps of the corresponding transformation and reinforcement strategy. The construction personnel can transform and reinforce the target transmission line tower according to the construction steps output by the control device.

[0047] In this embodiment, the target transmission line tower is first determined by the mining depth and post-mining ratio of the transmission line tower, so as to avoid reinforcing the transmission line towers that will not be affected by mining in the mining area. Compared with the existing scheme of reinforcing all the transmission line towers in the mining area, this implementation can reduce the waste of coal seams on the one hand and reduce the reinforcement cost on the other hand. Then, based on the mining subsidence prediction method, the deformation type of the target transmission line tower is determined, and the deformation type includes horizontal deformation exceeding the standard line tower and inclined deformation exceeding the standard line tower; finally, according to the deformation type of the target transmission line tower, the corresponding transformation and reinforcement strategy of the target transmission line tower is determined, so as to realize the purposeful transformation and reinforcement of the target transmission line tower, reduce the reinforcement cost by adjusting the reinforcement method, avoid the waste of coal resources and reduce the construction cost while ensuring the safe operation of the transmission line.

[0048] like Figure 2 As shown, in some embodiments, before determining the deformation type of the target transmission line tower based on the mining subsidence prediction method, the method includes: S300, determining the coal pressing range of the target transmission line tower.

[0049] Before calculating the subsidence of the line tower, it is necessary to clarify the mining range that will affect the line tower, that is, the coal compression range. Mining outside the coal compression range will not affect the line tower. This can reduce the waste of coal resources and minimize the waste of coal resources while ensuring the safe operation of the line tower.

[0050] Different towers have different protection levels and maintenance belt widths. For example, for a Class II UHV transmission line tower, the maintenance belt width is 15m. That is to say, the coal compression range for a Class II UHV transmission line tower is the area 15m away from the tower. Figure 3 The diagram shows the statistical diagram of the coal pressing range of multiple line towers. Construction outside the coal pressing range will not affect the line tower, or the impact on the line tower will be very small, and the line tower will not be tilted beyond the allowable range.

[0051] Specifically, the control device may have preset coal compression ranges for different types of line towers.

[0052] S400. Determine the predicted parameters of surface movement deformation within the coal compression range based on the measured data of the surface movement observation station and the measured data of the surrounding mines; the predicted parameters of surface movement deformation include subsidence coefficient, horizontal movement coefficient, mining influence propagation angle, inflection point offset distance and main influence angle tangent.

[0053] Specifically, the measured data of the surface movement observation station and the measured data of the surrounding mines are input into the control device. The control device can determine the predicted parameters of surface movement deformation within the coal pressure range according to the measured data of the surface movement observation station and the measured data of the surrounding mines. The predicted parameters of surface movement deformation include subsidence coefficient, horizontal movement coefficient, mining influence propagation angle, inflection point offset distance and / or main influence angle tangent, so as to predict the surface movement deformation within the coal pressure range, thereby providing a theoretical basis and scientific basis for the prediction of tower deformation and improving the accuracy of tower deformation.

[0054] Next, the control device uses the preset probability integral method calculation model to carry out calculation work and generate the tilt deformation value and the horizontal deformation value. Finally, the tower deformation type can be predicted based on the tilt deformation value and the horizontal deformation value, such as Figure 5 and Figure 6 shown.

[0055] In some embodiments, according to the deformation type of the target transmission line tower, determining the transformation and reinforcement strategy corresponding to the target transmission line tower includes: In the case of horizontal deformation exceeding the standard of the line tower, the reinforcement method of the joint cross-shaped steel beam pier structure transformation is adopted; In the case of a tower with an inclined deformation exceeding the standard, a transformation and reinforcement method is adopted in which an adjustable device is installed under the tower base.

[0056] Specifically, after determining the deformation type of the target transmission line tower, the control device will output a corresponding transformation and reinforcement strategy.

[0057] Furthermore, the reinforcement method of the joint cross-shaped steel beam pier structure modification is to use the cross-shaped steel beam 10 to push and fix the four towers of the target transmission line tower together, such as Figure 6 In this way, the four tower legs 30 are fixed as a whole, and the cross steel beam 10 resists the horizontal deformation of the ground surface, which can solve the problem of the tower legs 30 being subjected to excessive stress due to the asynchronous horizontal deformation of the tower legs 30, and improve the ability of the line tower to resist horizontal deformation.

[0058] like Figure 7As shown, further, the reinforcement structure of the modified reinforcement method with an adjustable device installed below the tower base includes a cross steel beam 10, four connecting components 20, a cap beam and an adjustment mechanism; the cross steel beam 10 is connected to the tower legs 30 of the target line tower, and the four tower legs 30 are located at the four intersections of the cross steel beam 10; the four connecting components 20 are connected end to end to form a quadrilateral, and the connecting components 20 are connected to the ends of the cross steel beam 10. The cap beam is arranged below the connecting component 20. The adjustment mechanism is installed on the cap beam, and the upper end of the adjustment mechanism is connected to the connecting component 20, which is used to adjust the inclination of the target transmission line tower through the connecting component 20.

[0059] The four towers of the target transmission line tower are pushed and fixed together using the cross steel beam 10. In this way, the four tower legs 30 are fixed as a whole, and the cross steel beam 10 resists the horizontal deformation of the ground surface, which can solve the problem of the tower legs 30 being subjected to excessive stress due to the asynchronous horizontal deformation between the tower legs 30, and improve the ability of the tower to resist horizontal deformation. By setting four connecting components 20, the four tower legs 30 and the cross steel beam 10 are adjusted as a whole. By setting a pedestal beam, an installation foundation can be provided for the adjustment mechanism. By setting an adjustment mechanism connected to the connecting component 20, the cross steel beam 10 and the tower leg 30 can be adjusted as a whole.

[0060] Further, the connection assembly 20 includes a connection beam 21 and an adjustment beam 22; the adjustment beam 22 is an L-shaped structure, and four adjustment beams 22 are arranged at the four corners of the well-shaped steel beam 10 and connected to the end of the well-shaped steel beam 10; four connection beams 21 are respectively arranged at the upper end, lower end, left end and right end of the well-shaped steel beam 10, and connected to the well-shaped steel beam 10 and the adjustment beam 22. By setting the adjustment beam 22, an installation foundation can be provided for the adjustment mechanism, and by setting the connection beam 21, the well-shaped steel beam 10 and the tower leg 30 can be adjusted as a whole.

[0061] Furthermore, the cap beam is a concrete structure.

[0062] Further, the adjustment mechanism includes a jack.

[0063] It should be noted that if the target transmission line tower has both tilt deformation and horizontal deformation that exceed the standard, it can also be reinforced by installing an adjustable device under the tower base.

[0064] In summary, the method for transformation and reinforcement of transmission towers in coal mining subsidence areas provided in this embodiment can count the deformation of the towers, select the towers that need to be processed, and then further classify the selected towers according to the deformation type, and propose special reinforcement methods based on the two deformation types.

[0065] This method is based on sufficient theoretical basis and good operability. It carries out surface tower management according to the impact of mining, avoiding the waste of a large amount of coal resources caused by the use of underground mining measures. At the same time, it refines the tower management area and means, reducing the transformation cost. This method is highly practical in protecting towers and improving mine production efficiency, and can meet the purpose of scientifically protecting transmission line towers.
