Description

Technical Field

[0001] This application relates to the field of landscape architecture technology, and in particular to a device and method for straightening trees that have fallen due to wind damage with a high survival rate. Background Technology

[0002] When a typhoon occurs, many trees in parks and green spaces are blown down. After the typhoon, sanitation workers use tree straightening devices to put the leaning or fallen trees back in their original positions.

[0003] Existing methods for straightening fallen trees typically include tying straps and a crane. When straightening a tree, sanitation workers first trim excess branches and leaves from the tree's crown. Then, they tie tying straps to the trunk, ensuring the straps are above the tree's center of gravity. Next, they connect the straps to the crane's hook and start the crane to lift the tree off the ground. Under its own weight, the tree will become nearly vertical. Finally, the crane is used to replant the tree in its original location.

[0004] However, when a tree is blown down to its leeward side, the roots on the leeward side of the tree are not damaged much. When the crane lifts the tree off the ground, these relatively intact roots are pulled out of the soil and damaged, thus reducing the survival rate of the tree after it is straightened.

[0005] In view of this, it is necessary to provide a device for straightening trees that have fallen due to wind disasters with a high survival rate and instructions on how to use it. Summary of the Invention

[0006] To address the problem that existing tree straightening devices cause damage to tree roots and stems during the straightening process, resulting in a low survival rate of the straightened trees, this application provides a high-survival-rate tree straightening device for wind-damaged trees and its usage method.

[0007] Firstly, the wind-damaged tree straightening device provided in this application with a high survival rate adopts the following technical solution: it includes a suspension assembly, a horizontal pulling assembly, and a controller. The suspension assembly includes a suspension unit and a support frame. The suspension unit can be connected to the tree and apply a vertically upward force to the tree. The suspension unit is slidably connected to the support frame and can slide along the direction close to or away from the windward side of the tree.

[0008] The horizontal pulling assembly includes a horizontal pulling unit and a detection device. The horizontal pulling unit can be connected to the tree and apply a force to the tree in the horizontal direction close to the windward side of the tree. The detection device is electrically connected to the controller and can detect whether the tree has an upward movement trend.

[0009] The controller is electrically connected with the suspension unit and can control the size of the force applied by the suspension unit to the tree according to the detection result of the detection device.

[0010] By adopting the technical scheme, on one hand, the suspension unit can apply an upward force to the tree, and the controller can cooperate with the detection assembly to ensure that the upward force is equal to the weight of the tree, so that the tree can be suspended at the current position, thereby ensuring that the parts of the root of the tree remaining in the soil are not pulled out of the soil and damaged; on the other hand, the horizontal pulling unit can apply a horizontal force close to the windward surface of the tree to the tree, so that the main stem of the tree can rotate to a vertical state with the root of the tree remaining in the soil as the center and close to the windward surface of the tree, and in the process of rotation of the main stem of the tree, the suspension unit slides along the support frame close to the windward surface of the tree and ensures that the direction of the upward force applied to the tree is always vertical upward, so that the upward force can offset the weight of the tree, which can not only reduce the friction between the parts of the root of the tree remaining in the soil and the surrounding soil, so that these parts are not easily damaged in the process of rotation of the main stem, but also can make the parts of the root of the tree exposed outside the soil not bear a large pressure and suffer secondary damage because they need to share the weight of the tree, so as to well reduce the damage to the root of the tree in the process of righting, thereby ensuring that the tree has a good survival rate after being righted.

[0011] Specifically, the suspension unit comprises a suspension piece, a driving cylinder and a tension sensor, the suspension piece is detachably connected with the tree, the support frame is provided with a guide rail in the direction close to or away from the windward surface of the tree, the cylinder body of the driving cylinder is provided on the guide rail in the vertical direction and can slide along the guide rail, the tension sensor is provided between the piston rod of the driving cylinder and the suspension piece and can detect the size of the force applied by the driving cylinder to the suspension piece, and the controller is electrically connected with the tension sensor.

[0012] By adopting the technical scheme, the driving cylinder can apply an upward force to the tension sensor, the suspension piece and the tree by retracting the piston rod; since the piston rod of the driving cylinder is gradually retracted into the cylinder body in the process of righting the tree, the tension sensor can feed back the size of the force to the controller, so that the controller can control the driving cylinder to always apply the same size of upward force to the tree in the process of righting the tree.

[0013] Further, the suspension piece comprises a mounting disc and a plurality of binding belts, the tension sensor is arranged at the top of the mounting disc, the piston rod of the driving cylinder is connected with the tension sensor, the bottom of the mounting disc is provided with a circular sliding groove around the center thereof, a plurality of sliding blocks are slidably connected in the circular sliding groove, and the sliding blocks correspond to the binding belts one by one.

[0014] By adopting the technical scheme, the user can bundle the plurality of first branches branched from the main rod of the tree by using the plurality of bundling belts.

[0015] Further, the bundling belt comprises a fixing belt and a connecting belt, one end of the fixing belt is connected with the sliding block, the other end of the fixing belt is provided with a buckle, one end of the connecting belt is connected with the sliding block, a row of connecting holes are opened on the belt body of the connecting belt along the length direction of the belt body, the buckle can be clamped with any connecting hole and connect the connecting belt with the fixing belt.

[0016] By adopting the technical scheme, the user can connect the fixing belt with any connecting hole on the belt body of the connecting belt by using the buckle, so that the bundling belt can bundle the first branches with different thicknesses.

[0017] Further, the belt body of the fixing belt is provided with a connecting sleeve, when the connecting belt is connected with the fixing belt, the end of the connecting belt away from the sliding block can pass through the connecting sleeve.

[0018] By adopting the technical scheme, after the buckle is clamped with one connecting hole on the belt body of the connecting belt, the user can insert the belt body between the connecting hole and the end of the connecting belt away from the sliding block into the connecting sleeve, so that the belt body can be limited by the connecting sleeve, thereby preventing the buckle from being loosened from the connecting hole.

[0019] Specifically, the flat-pulling unit comprises a connecting piece, a slide rail, a slide sleeve and a telescopic cylinder, the connecting piece can be connected with the tree, the slide rail is arranged on the connecting piece in the vertical direction, the slide sleeve is slidably connected on the slide rail, and the piston rod of the telescopic cylinder is arranged in the horizontal direction and is hinged on the slide sleeve.

[0020] The detection device is a pressure sensor arranged at the top end of the slide rail and capable of abutting with the slide sleeve.

[0021] By adopting the technical scheme, the telescopic cylinder can apply the force in the horizontal direction to the slide sleeve, the connecting piece of the slide rail and the tree through the piston rod; the user can move the slide sleeve to the position abutting with the pressure sensor before righting the tree, and a certain pressure exists between the slide sleeve and the pressure sensor, then the connecting piece is connected with the tree, when the upward pulling force applied by the suspension assembly is greater than the weight of the tree, the tree appears the upward movement trend, the tree drives the connecting piece and the slide rail to appear the upward movement trend, at this time, the reading of the pressure sensor is reduced, so that the controller can determine whether the tree appears the upward movement trend according to the change of the reading.

[0022] Furthermore, the flat-pull unit also includes an elastic element connected to the sliding sleeve and capable of applying a force close to the pressure sensor to the sliding sleeve.

[0023] By adopting the above technical solution, the elastic element can apply a force close to the pressure sensor to the sliding sleeve, so that there is a relatively stable pressure between the sliding sleeve and the pressure sensor before straightening the tree, which makes it easier for the controller to determine whether the tree is moving upward based on the change in pressure.

[0024] Furthermore, the connector includes a binding strap and a receiving strap. One end of the binding strap is connected to the slide rail, and a row of insertion holes is formed on the body of the binding strap along its length. One end of the receiving strap is connected to the slide rail, and the other end of the receiving strap is provided with a snap fastener, which can be snapped into any of the insertion holes.

[0025] By adopting the above technical solution, users can use the snap-fit ​​buckle to connect the receiving strap to any of the insertion holes on the strap, so that the connector can bind tree trunks of different thicknesses.

[0026] Specifically, it also includes a moving component, which includes a vehicle body and wheels. The support frame, the flat-pull unit, and the controller are all connected to the vehicle body. The wheels are located between the vehicle body and the ground and are rotatably connected to the vehicle body.

[0027] By adopting the above technical solution, the high survival rate straightening device for wind-fallen trees can be moved by setting up the vehicle body and wheels, thus making it convenient to straighten fallen trees in different regions.

[0028] The method of using the wind-damaged tree straightening device with a high survival rate provided in the second aspect of this application adopts the following technical solution:

[0029] S1. First, connect both the horizontal pulling unit and the suspension unit to the tree to be straightened and ensure that the center of gravity of the tree is located between the connection point of the horizontal pulling unit and the connection point of the suspension unit and the tree. Then, dig out the accumulated soil in the tree pit on the windward side of the tree and loosen the accumulated soil in the tree pit on the leeward side of the tree. Finally, repair the roots and stems of the tree that are exposed on the ground.

[0030] S2. The suspension unit is activated to apply a gradually increasing upward pulling force to the tree. When the detection device detects that the tree has an upward movement trend, the controller controls the suspension unit to maintain the magnitude of the upward pulling force.

[0031] S3. Activate the horizontal pulling unit to apply a horizontal force close to the windward side of the tree until the roots of the tree are completely inside the tree pit and the tree is in a vertical position;

[0032] S4. Close the horizontal pulling unit and the suspension unit, and fill and compact the soil in the tree pits of the trees.

[0033] By adopting the above-mentioned technical solutions, digging out the accumulated soil in the tree pit on the windward side of the tree before it falls allows the exposed roots to easily return to the pit; loosening the accumulated soil in the tree pit on the leeward side of the tree reduces the friction between the parts of the tree roots that remain in the soil and the surrounding soil, making these parts less susceptible to damage during the rotation of the trunk; and repairing the wounds on the exposed roots reduces the risk of infection and wilting at the wound sites, thereby further increasing the survival rate of the tree after it is straightened.

[0034] In summary, this application includes at least one of the following beneficial technical effects:

[0035] 1. A device comprising a suspension assembly, a horizontal tensioning assembly, and a controller. The suspension assembly includes a suspension unit and a support frame. The suspension unit is connected to a tree and applies a vertically upward force to the tree. The suspension unit is slidably connected to the support frame and can slide along the windward side of the tree, either close to or away from it. The horizontal tensioning assembly includes a horizontal tensioning unit and a detection device. The horizontal tensioning unit is connected to the tree and applies a horizontal force to the tree, close to its windward side. The detection device is electrically connected to the controller and can detect whether the tree has an upward movement tendency. The controller is electrically connected to the suspension unit and can control the magnitude of the force applied to the tree by the suspension unit based on the detection result of the detection device. On the one hand, the suspension unit can apply an upward tension force to the tree, and on the other hand, the controller can cooperate with the detection assembly to ensure that the upward tension force is equal to the tree's own weight, so as to suspend the tree in its current position and ensure that the parts of the tree's roots remaining in the soil are not pulled out of the soil. On the one hand, the straightening unit can apply a horizontal force to the tree close to its windward side, so that the main trunk of the tree can rotate to a vertical position with the rootstock left in the soil as the center. During the rotation of the main trunk, the suspension unit slides along the support frame towards the windward side of the tree and ensures that the direction of the upward force on the tree is always vertical and upward, so that the upward force can offset the tree's own weight. This reduces the friction between the parts of the tree rootstock left in the soil and the surrounding soil, so that these parts are not easily damaged during the rotation of the main trunk. It also prevents the parts of the tree rootstock exposed outside the soil from bearing too much pressure and suffering secondary damage due to the need to share the tree's own weight. This can effectively reduce the damage to the tree rootstock during the straightening process, thereby ensuring that the tree has a good survival rate after being straightened.

[0036] 2. Before a tree falls, digging up the soil in the tree pit on the windward side allows the exposed roots to easily return to the pit; loosening the soil in the tree pit on the leeward side reduces the friction between the roots and the surrounding soil, preventing damage during the rotation of the trunk; and repairing the exposed roots reduces the risk of infection and wilting, further increasing the survival rate of the tree after it is straightened.

[0043] The following is in conjunction with the appendix Figures 1-5 Further explanation:

[0044] See Figure 1 and Figure 2 In one embodiment, the high survival rate straightening device for wind-fallen trees includes a moving component 3, a suspension component 1, a horizontal pulling component 2, and a controller (not shown in the figure). The moving component 3 includes a vehicle body 31 and four wheels 32. The four wheels 32 are located between the vehicle body 31 and the ground and are rotatably connected to the vehicle body 31. The suspension component 1, the horizontal pulling component 2, and the controller are all located on the vehicle body 31. An engine (not shown in the figure) for driving the wheels 32 to rotate is also provided on the vehicle body 31, so that the high survival rate straightening device for wind-fallen trees has good mobility and is convenient for straightening fallen trees 4 in different areas.

[0045] See Figure 2 and Figure 3The suspension assembly 1 includes a support frame 12 and a suspension unit 11. The support frame 12 includes a column 121 and a crossbeam 122. The column 121 is erected on the vehicle body 31. One end of the crossbeam 122 is connected to the column 121, and the other end of the crossbeam 122 extends away from the vehicle body 31. A reinforcing rib 123 is also provided at the connection between the crossbeam 122 and the column 121. The suspension unit 11 includes a drive cylinder 112, suspension components, and a tension sensor 113. The crossbeam 122... A groove is provided on the crossbeam 122 along its length. The groove runs vertically through the entire crossbeam 122. Two guide rails 1221 are arranged opposite each other on the crossbeam 122 with the groove as the center. Each guide rail 1221 is arranged along the length of the crossbeam 122 and is connected to a slide block. The cylinder body of the drive cylinder 112 passes through the groove and is connected to the two slide blocks. The piston rod of the drive cylinder 112 extends downward in the vertical direction and is hinged to the top of the tension sensor 113.

[0046] It should be noted that before straightening the tree 4, the user can place the vehicle body 31 of this wind-damaged fallen tree straightening device on the windward side 43 of the tree 4 to be straightened, and make the end of the crossbeam 122 away from the vehicle body 31 span across the trunk 41 of the tree 4. This allows the guide rail 1221 to be set along the direction close to or away from the windward side 43 of the tree 4, and also allows the suspension to be connected to the first-level branch 42 extending from the trunk 41 of the tree 4.

[0047] See Figure 3 and Figure 4 Taking a tree 4 whose trunk 41 extends only three primary branches 42 as an example, the suspension component includes a mounting plate 111 and three sets of binding straps. The bottom of the tension sensor 113 is connected to the mounting plate 111. A circular groove is formed around the center of the bottom of the mounting plate 111. Three arc-shaped sliders 1111 are slidably connected in the circular groove. Each slider 1111 corresponds to a set of binding straps. The binding straps include a fixing strap 114 and a connecting strap 115. The bottom end of the fixing strap 114 is provided with a buckle 1141. The top end of the fixing strap 114 is connected to one end of the slider 1111. The top end of the connecting strap 115 is connected to the other end of the slider 1111. The connecting strap 115 extends along its own length. A row of connecting holes is provided, and the buckle 1141 can be engaged with any of the connecting holes to connect the connecting strap 115 with the fixing strap 114, so that the strapping can bind primary branches 42 of different thicknesses; a connecting sleeve 1142 is also provided on the strap body of the fixing strap 114, so that after the user uses the buckle 1141 to engage one of the connecting holes on the strap body of the fixing strap 114 and the connecting strap 115, the user can insert the strap body of the connecting strap 115 located between the connecting hole and the end of the connecting strap 115 away from the slider 1111 into the connecting sleeve 1142, so that the connecting sleeve 1142 can limit this part of the strap body, thereby making it difficult for the buckle 1141 to come loose from the connecting hole.

[0048] See Figure 2 and Figure 4 The flat-pull unit 21 includes a slide rail 212, a sliding sleeve 213, an elastic element 215, a telescopic cylinder 214, and two connecting parts. The slide rail 212 has a T-shaped cross-section and is arranged vertically. Slide end plates 2121 are provided at both ends of the slide rail 212. The sliding sleeve 213 is mounted on the slide rail 212 and can slide back and forth between the two slide end plates 2121. The detection device 22 is a pressure sensor, which is mounted on the slide end plate 2121 located at the top of the slide rail 212 and can interact with the sliding sleeve. 213 abuts, and the elastic element 215 is a pair of compression springs. The pair of compression springs are arranged opposite each other with the slide rail 212 as the center and are both arranged between the slide sleeve 213 and the slide end plate 2121 located at the bottom of the slide rail 212. The pair of compression springs can make the pressure applied to the pressure sensor by the slide sleeve 213 equal to the elastic force of the slide sleeve 213 when it is not subjected to other external forces. The cylinder body of the telescopic cylinder 214 is provided on the vehicle body 31, and the piston rod of the telescopic cylinder 214 is arranged in the horizontal direction and hinged to the slide sleeve 213.

[0049] See Figure 4 and Figure 5 Two connectors are positioned vertically opposite each other on the side of the slide rail 212 away from the sliding sleeve 213. Each connector includes a binding strap 211 and a receiving strap 216. One end of the binding strap 211 is connected to the slide rail 212, and a row of insertion holes is formed along its length on the strap. One end of the receiving strap 216 is connected to the slide rail 212, and the other end of the receiving strap 216 is provided with a snap fastener 2161 and a fixing sleeve 2162. The snap fastener 2161 can engage with any of the insertion holes, thus allowing the binding strap to... 211 and the receiving strap 216 can bind the trunks 41 of trees 4 of different thicknesses. After the user uses the snap fastener 2161 to snap the receiving strap 216 to a plug hole on the strap body of the binding strap 211, the strap body located between the plug hole and the end of the binding strap 211 away from the slide rail 212 is inserted into the fixing sleeve 2162. The fixing sleeve 2162 can limit this part of the strap body, so that the snap fastener 2161 is not easy to come loose from the plug hole.

[0050] The pressure sensor, drive cylinder 112, telescopic cylinder 214, and tension sensor 113 are all electrically connected to the controller. The control logic of the controller is as follows:

[0051] After the user connects the connector to the main trunk of tree 4 and connects the three sets of binding straps on the suspension plate to a primary branch 42, the controller first controls the drive cylinder 112 to retract the piston rod to apply an upward pulling force to the tension sensor 113, the suspension component, and tree 4. The tension sensor 113 will detect the magnitude of this upward pulling force in real time and feed the detection result back to the controller. When the upward pulling force applied by the drive cylinder 112 is greater than the weight of the tension sensor 113, the suspension component, and tree 4, tree 4 will cause the connector, slide rail 212, and pressure sensor to move upward together. At this time, the reading of the pressure sensor will decrease, so that the controller can determine that tree 4 has an upward movement trend and record the magnitude of the upward pulling force detected by the tension sensor 113. Then the controller will activate the telescopic cylinder 214 to retract the piston rod to apply a horizontal force to the sliding sleeve 213, the slide rail 212 connector, and tree 4, so that the main trunk of tree 4 can move towards the root stem of tree 4 remaining in the soil. The tree 4 is rotated to a vertical position near the windward side 43. During the rotation of the main trunk of the tree 4, the suspension unit 11 slides along the crossbeam 122 towards the windward side 43 of the tree 4, ensuring that the upward pull on the tree 4 is always vertical. During the sliding of the suspension unit 11, the controller uses the drive cylinder 112 and the tension sensor 113 to ensure that the magnitude of the upward pull on the tree 4 remains constant, so that the upward pull can offset the weight of the tree 4. This reduces the friction between the parts of the tree 4's roots that remain in the soil and the surrounding soil, preventing these parts from being easily damaged during the rotation of the main trunk. It also prevents the parts of the tree 4's roots exposed outside the soil from bearing excessive pressure and secondary damage due to sharing the weight of the tree 4. This effectively reduces damage to the roots of the tree 4 during the straightening process, thus ensuring a good survival rate for the tree 4 after it is straightened.

[0052] Based on the structure of the above-mentioned high survival rate straightening device for wind-fallen trees, the second aspect of this application also provides a method for using the high survival rate straightening device for wind-fallen trees. This method utilizes the above-mentioned high survival rate straightening device for wind-fallen trees, and specifically includes:

[0053] S1. First, connect both the horizontal pulling unit 21 and the suspension unit 11 to the tree 4 to be straightened and ensure that the center of gravity of the tree 4 is located between the connection point of the horizontal pulling unit 21 and the connection point of the suspension unit 11 and the tree 4. Then, dig out the accumulated soil in the tree pit on the windward side 43 of the tree 4 and loosen the accumulated soil in the tree pit on the leeward side 44 of the tree 4. Finally, repair the roots and stems of the tree 4 exposed on the ground.

[0054] S2. Start the suspension unit 11 to apply a gradually increasing upward pulling force to the tree 4. When the detection device 22 detects that the tree 4 has an upward movement trend, the controller controls the suspension unit 11 to maintain the magnitude of the upward pulling force.

[0055] S3. Activate the horizontal pulling unit 21 to apply a horizontal force close to the windward side 43 of the tree 4 until the roots of the tree 4 are completely inserted into the tree hole and the tree 4 is in a vertical position.

[0056] S4. Close the horizontal pulling unit 21 and the suspension unit 11, and fill and compact the soil in the tree pit of tree 4.

[0057] Since the method of using the wind-fallen tree straightening device of this application adopts the above-mentioned wind-fallen tree straightening device, it can also have all the technical effects of the above-mentioned wind-fallen tree straightening device. In particular, digging out the accumulated soil in the tree pit on the windward side 43 of the tree 4 before the tree 4 falls can facilitate the roots and stems of the tree 4 exposed outside the soil to return to the tree pit; loosening the accumulated soil in the tree pit on the leeward side 44 of the tree 4 can reduce the friction between the parts of the roots and stems of the tree 4 that remain in the soil and the surrounding soil, so that these parts will not be easily damaged during the rotation of the main trunk; repairing the wounds of the roots and stems of the tree 4 exposed on the ground can reduce the risk of infection and wilting at the wound site, so as to further increase the survival rate of the tree 4 after straightening.

[0058] Specifically, the procedure for repairing wounds on the rhizomes may include the following steps:

[0059] For tree roots with a broken area of ​​less than 1 / 2, first smooth the wound surfaces on both sides of the broken root, then apply disinfectant, then join the broken ends together and apply protective agent, and finally tie the wound tightly with film. For tree roots with a broken area of ​​more than 1 / 2, first cut off the broken root along the broken edge, then saw the end of the root flat, apply disinfectant and protective agent to the wound surface, and finally tie the wound tightly with film. For rotten roots, damaged roots, and completely broken roots, prune them together, and apply disinfectant and protective agent to the wounds created by pruning.

[0060] It should be noted that when the crown of tree 4 is large and the root system is severely damaged, the inner branches, vigorous branches, overlapping branches and other small branches of the crown can be pruned to reduce the weight of tree 4, reduce the pressure on the root system and the burden on nutrient supply, thereby improving the survival rate of tree 4 after it is straightened.

[0061] The implementation principle of the wind-damaged tree straightening device described in this application with a high survival rate is as follows:

[0062] After the user connects the connector to the main pole of tree 4 and connects the three sets of binding straps on the suspension plate to a primary branch 42, the controller will first control the drive cylinder 112 to retract the piston rod to apply an upward pulling force to the tension sensor 113, the suspension component, and tree 4. The tension sensor 113 will detect the magnitude of the upward pulling force in real time and feed the detection result back to the controller. When the upward pulling force applied by the drive cylinder 112 is greater than the weight of the tension sensor 113, the suspension component, and tree 4, tree 4 will drive the connector, slide rail 212, and pressure sensor to move upward together. At this time, the reading of the pressure sensor will decrease, so that the controller can determine that tree 4 has an upward moving trend and record the magnitude of the upward pulling force detected by the tension sensor 113 at this time.

[0063] Then the controller will activate the telescopic cylinder 214 to retract the piston rod, applying a horizontal force to the sliding sleeve 213, the sliding rail 212 connector, and the tree 4, so that the main trunk of the tree 4 can rotate to a vertical position with the rootstock of the tree 4 remaining in the soil as the center, towards the windward side 43 of the tree 4. During the rotation of the main trunk of the tree 4, the suspension unit 11 will slide along the crossbeam 122 towards the windward side 43 of the tree 4 as the tree 4 rotates, ensuring that the upward pulling force on the tree 4 is always vertically upward. During the sliding of the suspension unit 11, the controller will... The cooperation of the drive cylinder 112 and the tension sensor 113 ensures that the upward tension force on the tree 4 remains constant, so that the upward tension force can offset the self-weight of the tree 4. This reduces the friction between the parts of the tree 4's roots that remain in the soil and the surrounding soil, preventing these parts from being easily damaged during the rotation of the main pole. It also prevents the parts of the tree 4's roots that are exposed outside the soil from bearing excessive pressure and suffering secondary damage due to sharing the self-weight of the tree 4. This effectively reduces the damage to the tree 4's roots during the straightening process, thereby ensuring that the tree 4 has a good survival rate after being straightened.

Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
