Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

As shown in fig. 2, the conventional configuration of the long and short legs of the transmission tower is generally a forward configuration method, and the flow thereof is as follows:

inquiring a corresponding iron tower root opening according to the tower call height of the electric air investment, and drawing the iron tower root opening into a tower footing topographic map 7 according to a flat leg root opening value;

determining a design base surface value H1 of each tower leg according to the tower foundation terrain, namely the height difference between the design base surface 6 and the central pile 1;

determining a main column heightening value H2 of each foundation 2 according to the tower footing topography, namely the difference between the design base surface 6 and the bottom surface of the tower footing plate;

calculating the height difference between the top surface of each tower leg foundation and the center pile 1, wherein the height difference is H1+ H2;

selecting proper tower legs according to the height difference value between the foundation jacking height of each tower leg and the central pile 1;

and determining the tower nominal height H4 according to the height difference between the top surface of the foundation with the longest leg and the central pile 1, and verifying whether the tower nominal height H4 meets the requirement.

In the method, for example, the electric tower pitch ratio is 2F2W9-J3-30, the tower slope ratio is 0.14, the half-root of the tower leg base 2 of 30 meters is 5580mm, the tower base topographic map 7 (drawn by the height difference contour line 71 of 0.5 meter) is drawn corresponding to the iron tower root according to the tower nominal height query, a graph shown in fig. 3 is obtained, configuration is performed on the basis of fig. 3, it can be found that the actual leg length of each tower leg is changed with the electric tower pitch, the configuration result is drawn into the tower base topographic map 7 again according to the actual half-root opening value of each leg, and as a result, as shown in fig. 4, the tower leg position change amplitude is larger when the tower slope ratio is larger or the topography is steeper, and the change of the base plane is also likely to be more obvious. The main column height H2 also changes after the configuration, with an increase and a decrease. If the manual reconfiguration method according to the actual position is adopted, the workload is obviously increased, and the process with slow configuration speed is more inefficient. And when high and low legs are configured manually in a conventional mode, determining a base design base plane 6 according to a half base opening value of the base, then determining a main column heightening value H2, and finally selecting and connecting legs 3 and calculating the tower call height H4. And determining tower nominal height H4 (namely the vertical distance between the bottom surface of the cross arm of the lowest layer of the conducting wire and the construction base surface of the tower center pile 1) after the connecting leg 3 is selected. The main column height H2 is not accurate because the half-opening value of the final selected leg 3 may not be consistent with the half-opening value selected for the initial leg matching, and the accuracy can be improved by continuous iteration. Therefore, the existing configuration method has low configuration speed and insufficient accuracy.

Based on this, the present application intends to provide a solution to the above technical problem, the details of which will be explained in the following embodiments.

In one embodiment, as shown in fig. 1, there is provided a method for configuring high and low legs of a power transmission tower, comprising the steps of:

s102: and acquiring a target call scale height, determining a candidate leg set according to the target call scale height, and taking the candidate leg set with the highest priority as the target leg set.

The target calling height is the tower calling height H4, and is the vertical distance from the bottom surface of the lowest layer wire cross arm of the power transmission tower to the tower center pile 1.

Specifically, a target call height can be determined according to the electric air investment, and a range of a leg connection call height H3 corresponding to the target call height can be determined according to the target call height, wherein the leg connection call height H3 is a vertical distance between the bottom surface of a leg connection 3 serving as a tower leg and the bottom surface of the lowest wire cross arm of the power transmission tower. For example, the electric field investment is 2F2W9-J3-30, center peg 10.5 m. The electrically promoted tower leg call height is 30m, the height difference of the central pile 1 is 0.5m, the target call height is 30.5m, and the call height H3 of the connecting leg 3 is close to the target call height. Therefore, three candidate leg sets can be initially selected according to the target call height, the call height reference values of the candidate leg sets can be respectively 30m, (30+ X) m and (30+2X) m, the three candidate leg sets are respectively {30, 30-1, …, 30-n }, {30+ X, 30+ X-1, …, 30+ X-n } and {30+2X, 30+2X-1, …, 30+2X-n }, wherein X is the difference value of the call height reference values of two adjacent candidate leg sets, n is the value obtained by subtracting one from the number of legs in the candidate leg set, X and n are determined according to actual needs, and exemplarily, X is 3, and n is 7. The priority of each candidate leg set is related to a reference value, the higher the reference value is closer to the target call scale, the higher the priority is, when X is a positive value, the priorities of the three candidate leg sets are ranked from high to low as {30, 30-1, …, 30-n } {30+ X, 30+ X-1, …, 30+ X-n }, {30+2X, 30+2X-1, …, 30+2X-n }. The candidate leg set is related to the allowable height of the tower leg, and if the allowable maximum height is 33 meters and X is 3, only two candidate leg sets with the call height reference value of 30m and (30+ X) m exist.

S104: and traversing and selecting each connecting leg 3 in the current target connecting leg set as a certain tower leg of the power transmission tower, respectively calculating the basic exposure height h when each connecting leg 3 in the current target connecting leg set is used as a tower leg by a preset algorithm, determining the optimal connecting leg serving as the tower leg according to the calculation result, and repeating the process to determine the optimal connecting leg of each tower leg of the power transmission tower.

Specifically, the transmission tower generally includes four tower legs, namely a first tower leg, a second tower leg, a third tower leg and a fourth tower leg. When the current target leg connecting set is determined, each leg connecting 3 in the current target leg connecting set is selected as a first tower leg in a traversing mode, the basic exposure height h when each leg connecting 3 in the current target leg connecting set is used as the first tower leg is calculated, the calculated basic exposure height h is compared, and the optimal leg connecting serving as the first tower leg can be determined. And then repeating the process for the second tower leg, the third tower leg and the fourth tower leg, so that the optimal connection legs of the second tower leg, the third tower leg and the fourth tower leg can be respectively determined, and the optimal connection legs of all the tower legs of the transmission tower are finally determined.

S106: and determining the design base surface value H1 and the main column height value H2 of each tower leg according to each optimal leg connection.

Specifically, after the optimal leg connection of all tower legs of the power transmission tower is determined, the related data of each optimal leg connection can be obtained, after the related data of the optimal leg connection are obtained, the drop point 5 of each optimal leg connection, namely the drop point 5 of each tower leg, can be determined by combining a topographic map of the pre-built position of the power transmission tower, and therefore the design base surface value H1 and the main column heightening value H2 of each tower leg are determined.

The power transmission tower high-low leg configuration method comprises the steps of firstly obtaining a target call height, then determining a target connection leg set according to the target call height, traversing and selecting each connection leg 3 in the target connection leg set as a certain tower leg of a power transmission tower, determining a basic exposure height H corresponding to the tower leg according to the selected connection leg when the selected connection leg is used as the tower leg, traversing and selecting each connection leg 3 of the target connection leg set, obtaining the basic exposure height H corresponding to the tower leg when each connection leg 3 is used as the tower leg, comparing the basic exposure heights H, determining an optimal connection leg serving as each tower leg, repeating the above processes, determining the optimal connection leg of each tower leg of the power transmission tower, and then determining a designed base surface value H1 and a main column height value H2 of each tower leg according to each optimal connection leg, so that a finally obtained configuration scheme meets actual requirements and configuration precision is high; and the whole process can be automatically completed through computer equipment, and the configuration efficiency is relatively high.

In one embodiment, the calculating the base exposure h when each leg 3 is taken as the leg 3 of the tower leg by using a preset algorithm comprises:

s1022: and determining a falling point 5 of the bottom end of the selected leg on a pre-stored tower footing topographic map 7 according to the half-root data of the iron tower with the selected leg.

The half-open data of the iron tower is the distance between the bottom end of the selected connecting leg and the center line of the power transmission tower, namely the distance between the bottom end of the selected connecting leg and the center pile 1 of the power transmission tower. After the connecting leg is selected, the bottom end of the connecting leg 3 is projected to be a point, the point has a position on the natural ground 4 and is mapped on the tower footing topographic map 7, namely the drop point 5 of the bottom end of the selected connecting leg on the prestored tower footing topographic map 7 is selected.

Specifically, the position of the center pile 1 of the power transmission tower is determined in advance, and since the tower footing topographic map 7 is a plan view with the contour lines 71, the position of the center pile 1 is taken as a reference, and the falling point 5 of the bottom end of the selected leg on the pre-stored tower footing topographic map 7 can be determined according to the half-open data of the tower with the selected leg.

S1024: and determining the ground elevation of the drop point position according to the drop point 5.

Specifically, after determining a drop point 5 of the bottom end of the selected leg on the tower footing topographic map 7, contour lines 71 adjacent to the drop point 5 on the tower footing topographic map 7 can be obtained according to the position of the drop point 5, and then the ground elevation of the drop point position is determined according to the adjacent contour lines 71.

S1026: and determining the elevation of the bottom plate of the tower leg according to the selected call height of the connecting leg, the target call height and the prestored elevation of the center pile.

Wherein, because the position of the central pile 1 is known, the height of the central pile can be measured in advance. The height of the bottom plate of the tower leg is the height of the bottom end of the selected connecting leg.

Specifically, since the target call height is the vertical distance from the lower plane of the lowermost cross arm of the power transmission tower to the tower center pile 1, the elevation of the lower plane of the lowermost cross arm of the power transmission tower can be determined according to the target call height and the elevation of the center pile, and the elevation of the bottom end of the selected leg, namely the elevation of the tower foot bottom plate, can be determined based on the elevation of the lower plane of the lowermost cross arm of the power transmission tower and the call height of the selected leg. The elevation of a tower foot bottom plate is equal to the elevation of the central pile plus the target calling height, and the calling height of the selected connecting leg is selected.

S1028: and calculating the difference value between the elevation of the bottom plate of the tower leg and the elevation of the ground to obtain the base exposure height h when the connecting leg is selected as the tower leg.

Specifically, the foundation 2 is used for supporting and selecting the connecting legs, the top surface elevation of the foundation 2 is the tower foot bottom plate elevation, and the difference value between the tower foot bottom plate elevation and the ground elevation is the height that the foundation 2 is higher than the ground 4, namely the foundation exposure height h.

In one embodiment, determining the ground elevation of the drop point location from the drop point 5 comprises:

s10242: if the drop point 5 falls on the contour line 71 of the tower footing topographic map 7, the ground elevation at the drop point location is the elevation of the contour line 71 on which the drop point 5 falls.

Illustratively, if the drop point 5 falls on a contour 71 having an elevation of M, then the drop point location has a ground elevation of M.

S10244: if the falling point 5 falls between the contour lines 71 of the tower footing topographic map 7, calculating the elevation of the falling point 5 by a preset interpolation algorithm, wherein the ground elevation of the falling point is the elevation of the falling point 5.

Specifically, when the drop point 5 is between the contour lines 71, the elevation of the ground 4 at the drop point 5 cannot be directly obtained, and plane interpolation calculation is required.

Illustratively, two contour lines 71 adjacent to the drop point 5 are respectively a first contour line and a second contour line, a point is taken on the first contour line, two points are taken on the second contour line, the three points are taken to form a plane, and the tower leg drop point 5 falls on the plane. A plane equation can be calculated through the selected three points, the plane coordinate of the drop point 5 can be obtained according to the coordinate of the central pile 1 and the half-open data of the iron tower with the selected connecting legs, and the ground elevation of the drop point position can be calculated by substituting the plane coordinate of the drop point 5 into the plane equation.

In one embodiment, determining the optimal leg as the tower leg according to the calculation result comprises:

s1042: and determining qualified connecting legs serving as tower legs according to the calculation result, and if a plurality of qualified connecting legs exist, comparing the basic exposure height h corresponding to each qualified connecting leg to determine the optimal connecting leg of the tower legs.

When the base exposure height h corresponding to the selected leg is within the allowable range, the selected leg is a qualified leg; and when the base exposure h corresponding to the selected leg is not in the allowable range, the selected leg is a unqualified leg. And there may be more than one qualified leg. Therefore, the optimal leg connection needs to be determined, and if the base exposure height h corresponding to the qualified leg connection is zero, the qualified leg connection is the optimal leg connection. If the base exposure height h corresponding to the qualified connecting legs is not zero, comparing the base exposure height h corresponding to each qualified connecting leg according to a preset priority mode to determine the optimal connecting leg of the tower leg, and if the base exposure height h is set to be exposed preferentially, taking the qualified connecting leg with the corresponding base exposure height h being greater than zero and closest to zero as the optimal connecting leg; and if the priority of the base descending is set, taking the qualified leg with the corresponding base exposure height h closest to zero as the optimal leg.

After step S104, the method further includes:

s105: and when the qualified leg connection of all tower legs cannot be determined according to the step S104, selecting the candidate leg connection set with the secondary priority as the target leg connection set, and returning to the step S104.

Illustratively, three candidate leg connecting sets are determined according to the target call balance, namely a first leg connecting set, a second leg connecting set and a third leg connecting set, and the three candidate leg connecting sets are sorted into the first leg connecting set, the second leg connecting set and the third leg connecting set from high to low in priority. And when the first leg connecting set is the current target leg connecting set, based on the fact that the first leg connecting set cannot determine qualified leg connecting of all tower legs, selecting the second leg connecting set as the target leg connecting set, and returning to the step S104. And when the qualified leg joints of all tower legs cannot be determined based on the second leg joint set, selecting the third leg joint set as the target leg joint set, and returning to the step S104.

In another embodiment, determining the optimal leg as the tower leg according to the calculation result includes:

judging whether the basic exposure height h corresponding to the selected leg is within an allowable range, if not, directly selecting the next leg 3; if yes, determining the selected leg as the current optimal leg of the tower leg, and then selecting the next leg 3; after the next connecting leg 3 is selected, judging whether the basic exposure height h corresponding to the connecting leg 3 is in an allowable range, if so, judging whether the basic exposure height h corresponding to the connecting leg 3 is superior to the basic exposure height h corresponding to the current optimal connecting leg, when the basic exposure height h corresponding to the connecting leg 3 is superior, determining the connecting leg 3 as the current optimal connecting leg, and then continuously selecting the next connecting leg 3; and if the base exposure height h corresponding to the leg connecting 3 is not in the allowable range or the base exposure height h corresponding to the leg connecting 3 is not superior to the base exposure height h corresponding to the current optimal leg connecting, directly continuing to select the next leg connecting 3. And repeating the process until all the connecting legs 3 in the current target connecting leg set are selected in a traversing manner, and if the current optimal connecting leg exists, the current optimal connecting leg is the optimal connecting leg of the tower leg. Wherein the optimal criterion is that the base exposure h is equal to zero. When the compared basic exposure height h is not zero, if the exposure is set to be preferential, the more preferable standard is that the basic exposure height h is larger than zero and smaller; if the base down priority is set, then the more preferred criterion is that the base exposure h is closer to zero.

In one embodiment, the above process is repeated until the target leg connecting set is the candidate leg connecting set with the lowest priority, and after the qualified leg connecting sets of all tower legs cannot be obtained based on the target leg connecting set, the method further includes:

s1052: and judging whether the target call height is reduced to a preset minimum allowable value or not, if so, ending the processing process and outputting corresponding preset information.

Specifically, when the leg 3 with all candidate legs concentrated is selected in a traversing manner and the qualified legs of all tower legs cannot be obtained, only the target call height can be reduced at the moment. The single reduction value of the target nominal height is a preset value, and if the target nominal height is reduced to a preset minimum allowable value, the target nominal height cannot be reduced any more, so that the processing process can only be finished, corresponding preset information is output, and the configuration of the high and low legs of the power transmission tower cannot be completed.

S1054: if not, the target call balance height is gradually reduced according to a preset rule, after each reduction operation, the target connection leg set is ensured to be a candidate connection leg set with the highest priority, the step S104 is repeatedly executed, and when the target call balance height is reduced to a preset minimum allowable value and qualified connection legs of all tower legs still cannot be obtained, the processing process is ended, and corresponding preset information is output.

Specifically, after the target call height is reduced by the preset value, the process of determining the optimal leg connection of each tower leg is repeated (i.e., step S104 and the subsequent step of determining the optimal leg connection of each tower leg are repeated), and if the qualified leg connections of all the tower legs cannot be obtained yet, the target call height is reduced by the preset value again, and the process of determining the optimal leg connection of each tower leg is performed again. And repeating the circulation process until the optimal leg connection (the optimal leg connection is a qualified leg connection) or the target call height of each tower leg is determined to be reduced to a preset minimum allowable value. If the optimal leg connection of each tower leg is determined, continuing to perform the next step (namely step S106); if the target call balance is reduced to the preset minimum allowable value, the qualified leg connection of all tower legs still cannot be obtained, the processing process is ended, and corresponding preset information is output.

In one embodiment, calculating the design base height value H1 and the main column height value H2 of each tower leg according to the optimal leg connection of each tower leg comprises:

s1062: and determining a target landing point 5 of each tower leg according to the optimal leg connection of each tower leg.

Specifically, after the optimal leg connection of each tower leg is determined, the falling point 5 of each tower leg can be determined according to the half-open data of the iron tower of the optimal leg connection of each tower leg and the coordinates of the central pile 1.

S1064: and constructing a basic protection circle 51 in a pre-stored tower footing topographic map 7 by taking the target landing point 5 of each tower leg as a circle center.

Specifically, the foundation 2 needs a certain protection range because the foundation 2 is difficult to function when the pile soil is small. And constructing a basic protection circle 51 on the tower footing topographic map 7 by taking the target falling point 5 as a circle center and a preset radius value as a radius.

S1066: the design base level height H1 of each tower leg is determined according to the height of the lowest point of the range of each basic protection circle 51.

Specifically, when the adjustment program is not set or started in advance, the lowest point in the range of the basic protection circle 51 is directly used as the tower leg design base 6, that is, the calculation starting point of the effective burial depth, and then the elevation of the lowest point in the range of each basic protection circle 51 is the design base elevation H1 of each tower leg. If the adjustment procedure is started in advance, the lowest point within the range of the basic protection circle 51 is adjusted, and the adjusted result is used as the tower leg design base 6 and the design base elevation H1 of the corresponding tower leg, for example, the adjustment procedure is rounded down, and the lowest point within the range of the basic protection circle 51 is-0.41 and is adjusted to-0.5.

S1068: and determining the design base surface value H1 and the main column height value H2 of each tower leg according to the design base surface elevation of each tower leg.

Specifically, the height difference from the design base 6 to the center pile is a design base value, and the height difference from the design base 6 to the bottom surface of the tower foot plate is a main column height value. And when the optimal leg connection of each tower leg is determined, the elevation of the bottom surface of the tower foot plate of each tower leg can be obtained based on the related data of the optimal leg connection, and the elevation of the central pile is known. Therefore, the main column height value H2 of each tower leg can be determined according to the design base elevation of each tower leg and the height of the tower foot plate bottom, and the design base elevation and the center pile elevation of each tower leg can be determined to be the design base elevation H1 of each tower leg.
