Description

Technical Field

[0001] This application relates to the technical field of borehole measurement, and particularly to a borehole inclination measurement device. Background Art

[0002] Borehole inclination measurement is an important task in fields such as engineering geological exploration, mine exploitation, and building construction. Accurate borehole inclination angle data is of great significance for ensuring project quality and improving resource utilization. Traditional borehole inclination measurement methods usually rely on manual observation and recording. Although these methods are simple and easy to implement, their accuracy and reliability are poor in complex environments. With the progress of technology, various automated measurement devices have gradually been applied to actual production, greatly improving work efficiency and measurement accuracy.

[0003] Currently, the commonly used borehole inclination measurement methods mainly include on-site measurement using optical instruments such as level gauges and theodolites, or real-time monitoring of the borehole attitude through sensors installed on the drill tool. Among them, the optical instrument method requires high operation skills and is greatly restricted by weather conditions; while the sensor-based method can achieve continuous monitoring, but has a high cost and complex maintenance.

[0004] The above traditional methods generally have some deficiencies. For example, in complex terrain conditions, the field of view of optical instruments is limited and accurate data cannot be effectively obtained; although the sensor system can provide relatively stable measurement results, its high cost and cumbersome calibration process limit its application scope. Especially in the field operation environment, how to quickly and conveniently complete the measurement of the borehole inclination angle has become an urgent problem to be solved. Therefore, it is particularly important to develop a borehole inclination measurement device that can work stably in different environments. Summary of the Invention

[0005] In order to overcome the above technical problems, this application provides a borehole inclination measurement device.

[0006] A borehole inclination measurement device provided by this application adopts the following technical solutions:

[0007] A borehole inclination measurement device includes a positioning component and an operation box; the operation box is arranged on the positioning component, and the positioning component is used to assist the operation box in positioning; a limiting rod and a lead screw are arranged in the operation box, the limiting rod is vertically arranged and fixedly connected to both the top surface and the bottom surface inside the operation box, the lead screw is also vertically arranged and rotatably connected to both the top surface and the bottom surface inside the operation box; a moving block is slidably sleeved on the limiting rod along the vertical direction, and one side of the moving block away from the limiting rod is in screw drive connection with the lead screw; a display component is arranged on one side of the moving block, and the display component is used to display the inclination angle of the borehole;

[0008] A first telescopic rod is fixedly connected to the bottom of the operation box. The first telescopic rod is a multi-stage telescopic rod and is vertically arranged. The first telescopic rod has a hollow interior structure. A second telescopic rod is provided inside the first telescopic rod. The second telescopic rod is also a multi-stage telescopic rod and is coaxially arranged with the first telescopic rod. The top end of the second telescopic rod is fixedly connected to the bottom end of the lead screw. The second telescopic rod is rotatably connected to the inner wall of the first telescopic rod. A first bevel gear is fixedly connected to the bottom end of the second telescopic rod. The first bevel gear is coaxially arranged with the second telescopic rod.

[0009] A hinge block is fixedly connected to the bottom end of the first telescopic rod. A rotating shaft is rotatably connected to the hinge block. The length direction of the rotating shaft is horizontal. A second bevel gear is fixedly sleeved on the rotating shaft. The second bevel gear is coaxially arranged with the rotating shaft. The top end of the second bevel gear meshes with the first bevel gear. A connecting rod is fixedly connected to the rotating shaft. The length direction of the connecting rod is perpendicular to the length direction of the rotating shaft. A third telescopic rod is fixedly connected to the end of the connecting rod away from the rotating shaft. The third telescopic rod is also a multi-stage telescopic rod. A heavy wheel is fixedly arranged at the end of the third telescopic rod away from the connecting rod. An expansion damping is provided inside the third telescopic rod to make the expansion and contraction resistance of the third telescopic rod greater than that of the first telescopic rod and the second telescopic rod.

[0010] By adopting the above technical solutions, the drilling inclination measuring device can achieve accurate measurement of the drilling inclination angle. Specifically, the design of the positioning component and the operation box enables the operation box to be stably placed at different positions, ensuring the stability during measurement. The cooperation of the limiting rod and the lead screw in the operation box enables the moving block to move smoothly in the vertical direction, thereby driving the display component to move in the vertical direction, facilitating the reading of the drilling inclination angle through the display component. The multi-stage design and the hollow interior structure of the first telescopic rod and the second telescopic rod not only enable the normal operation of the entire structure but also increase the measurement range. The first bevel gear at the bottom end of the second telescopic rod meshes with the second bevel gear on the rotating shaft to form a transmission system, enabling the heavy wheel at the end of the third telescopic rod to swing freely and automatically adjust to the corresponding state, thereby more accurately reflecting the actual inclination of the drilling. The combined design of the connecting rod and the third telescopic rod further enhances the flexibility and adaptability of the entire system, making it suitable for the measurement of drilling inclination in various complex environments.

[0011] The drilling inclination device is used for measuring the inclination angle between the upper section and the lower section of the drilling hole. During measurement: first, the heavy wheel is placed in the drilling hole, and the heavy wheel moves downward under the action of its own gravity, driving the third telescopic rod to move downward, and driving the rotating shaft to move downward. Since the telescopic damping of the third telescopic rod is greater than the telescopic damping of the first telescopic rod and the second telescopic rod, the first telescopic rod and the second telescopic rod are extended first until the heavy wheel contacts the inclination angle of the drilling hole, and the heavy wheel moves into the inclined lower drilling hole and contacts the bottom wall of the drilling hole, and the heavy wheel continues to roll downward, driving the third telescopic rod to extend; while the heavy wheel enters the lower drilling hole, it drives the third telescopic rod to tilt, and the third telescopic rod drives the rotating shaft to rotate through the connecting rod, and the rotating shaft drives the second bevel gear to rotate, and the second bevel gear drives the second telescopic rod to rotate, and the second telescopic rod drives the screw to rotate, and the screw rotation drives the moving block to move, and the moving block drives the display component to move, so that the inclination angle is displayed through the display component.

[0012] Optionally, it also includes a rotating plate; the positioning assembly includes a positioning plate, and the positioning plate is horizontally arranged; the rotating plate is arranged on the positioning plate and is rotatably connected to the positioning plate; the operating box is arranged on the rotating plate.

[0013] By adopting the above technical solution, since the angle of change of the drilling direction is uncertain, the operation box can be rotated relative to the positioning plate by setting the rotating plate, so that the position and angle of the operation box can be flexibly adjusted to meet the drilling inclination measurement requirements in different directions. This not only improves the applicability and flexibility of the measuring device, but also simplifies the operation process and improves work efficiency.

[0014] Optionally, it further includes a sliding component, which is slidably arranged on the rotating plate along a horizontal direction; and the operating box is rotatably arranged on the sliding component.

[0015] By adopting the above technical solution, the sliding assembly enables the operating box to slide in the horizontal direction on the rotating plate, thereby realizing the inclination measurement of boreholes at different positions; at the same time, the operating box can rotate around the sliding assembly, further improving the flexibility and adaptability of the device, and being able to better meet the use requirements under different working conditions; when the upper section of the borehole is tilted, the process of the heavy wheel entering the upper section of the borehole will drive the first telescopic rod and the second telescopic rod to tilt, thereby driving the operating box to tilt, and driving the sliding assembly to slide to a corresponding position.

[0016] Optionally, a slide groove is provided on the rotating plate, the length direction of the slide groove is the horizontal direction, the depth direction of the slide groove is the vertical direction, the slide groove penetrates the rotating plate along the vertical direction, and a slider is provided in the slide groove for sliding along its length direction.

[0017] By adopting the above technical solution, the design of the sliding groove enables the slider to slide freely in the horizontal direction, thereby realizing the position adjustment of the operation box in the horizontal direction, enabling the device to cope with the working condition of the upper section of the drill hole being inclined, and increasing the applicable range. This not only improves the flexibility and applicability of the measuring device, but also ensures that the operation during the drill hole inclination measurement is more convenient and accurate.

[0018] Optionally, the longitudinal section of the sliding groove is T-shaped, and the longitudinal section of the slider is also T-shaped, and the size is adapted to the size of the sliding groove.

[0019] By adopting the above technical solution, the design of the T-shaped sliding groove and the T-shaped slider enables the slider to slide stably in the sliding groove, prevents the slider from slipping out of the sliding groove, and improves the reliability and stability of the device.

[0020] Optionally, a sliding plate is fixedly connected to the top of the slider, the cross-sectional dimension of the sliding plate is larger than the cross-sectional dimension of the slider, and the bottom surfaces on both sides of the sliding plate are in contact with the top surface of the rotating plate; a first communication groove is formed in the sliding plate; a second communication groove is formed in the slider; the first communication groove penetrates through the sliding plate in the vertical direction, the second communication groove penetrates through the slider in the vertical direction, and the first communication groove and the second communication groove communicate with each other; both the first telescopic rod and the second telescopic rod can pass through the first communication groove.

[0021] By adopting the above technical solution, the sliding plate fixedly connected to the top of the slider can effectively increase the contact area between the slider and the rotating plate, and improve the stability and reliability during the sliding process. At the same time, the bottom surfaces on both sides of the sliding plate are in contact with the top surface of the rotating plate, which can prevent the slider from shaking or shifting in the sliding groove, and ensure the precise movement and positioning of the operation box in the horizontal direction.

[0022] Optionally, a support plate is fixedly connected to both sides of the top of the sliding plate, the support plate is vertically arranged, the operation box is arranged between the two support plates, and both sides of the operation box are rotatably connected to one of the support plates, and the axis direction of the rotation of the operation box is parallel to the axis direction of the rotating shaft.

[0023] By adopting the above technical solution, the support plates fixed to both sides of the top of the sliding plate can effectively stabilize the position of the operation box and ensure the stability of the operation box during use. At the same time, the rotational connection between the operation box and the support plate enables the operation box to rotate freely on the horizontal plane, facilitating rotation together with the rotation of the first telescopic rod. The axis direction of the rotation of the operation box is parallel to the axis direction of the rotating shaft, further ensuring the smoothness and flexibility of the operation box, and improving the accuracy and reliability of the drill hole inclination measurement.

[0024] Optionally, a rotating ring is fixedly sleeved on the bottom end of the outer wall of the second telescopic rod, a ring-shaped rotating groove is formed in the bottom end of the inner wall of the first telescopic rod, the size of the rotating groove is adapted to the size of the rotating ring, and the rotating ring is rotatably arranged in the rotating groove.

[0025] By adopting the above technical solution, it can ensure the stable rotation of the second telescopic rod relative to the first telescopic rod, thereby guaranteeing the stability and accuracy of the drilling inclination measuring device during the working process. The design of the rotating ring and the rotating groove effectively reduces the friction force and prolongs the service life of the device.

[0026] Optionally, the display component includes a moving rod and a display board. The moving rod is horizontally arranged, one end of the moving rod is located inside the operation box and is fixedly connected to the moving block; the other end of the moving rod is located outside the operation box and is fixedly connected to the display board. The display board is vertically arranged and is attached to the outer side wall of the operation box.

[0027] By adopting the above technical solution, the display component can accurately and intuitively display the inclination angle of the drilling. Specifically, the moving rod is fixedly connected to the moving block. When the lead screw rotates to drive the moving block to move up and down, the moving rod also moves accordingly, thereby driving the display board to move synchronously in the vertical direction. The display board is closely attached to the outer side wall of the operation box, and the corresponding angle information can be obtained through the display board.

[0028] Optionally, a moving groove is formed in the outer side wall of the operation box. The length direction of the moving groove is the vertical direction.

Detailed Embodiment

[0040] The following further describes the present application in detail Figures 1-5 in conjunction with the attached drawings.

[0041] The embodiment of the present application discloses a drill hole inclination measuring device. Referring to Figure 1 , a drill hole inclination measuring device, includes a positioning component 1, an operation box 2, a rotating plate 3, and a sliding component 4.

[0042] Reference Figure 2 and Figure 3 As shown in FIGS.

[0043] Reference Figure 2 and Figure 3 The operation box 2 is arranged on the positioning component 1, and the positioning component 1 is used to assist the positioning of the operation box 2. The operation box 2 is provided with a limiting rod 21 and a lead screw 22. The limiting rod 21 is vertically arranged and fixedly connected to both the top surface and the bottom surface inside the operation box 2. The lead screw 22 is also vertically arranged and rotatably connected to both the top surface and the bottom surface inside the operation box 2. A moving block 23 is slidably sleeved on the limiting rod 21 in the vertical direction. One side of the moving block 23 away from the limiting rod 21 is in screw transmission connection with the lead screw 22. A display component 5 is arranged on one side of the moving block 23, and the display component 5 is used to display the inclination angle of the drill hole.

[0044] Reference Figure 4 As shown in FIGS.

[0045] Reference Figure 2 and Figure 4 A first telescopic rod 6 is fixedly connected to the bottom of the operation box 2. The first telescopic rod 6 is a multi-stage telescopic rod and is vertically arranged. The first telescopic rod 6 is of a hollow structure inside. A second telescopic rod 7 is arranged inside the first telescopic rod 6. The second telescopic rod 7 is also a multi-stage telescopic rod and is coaxially arranged with the first telescopic rod 6. The bottom end of the lead screw 22 is located outside the operation box 2. The top end of the second telescopic rod 7 is fixedly connected to the bottom end of the lead screw 22, and the second telescopic rod 7 is rotatably connected to the inner wall of the first telescopic rod 6.

[0046] This drilling inclination device is applied to measure the inclination angle between the upper and lower sections of a drill hole. When measuring: First, place the heavy wheel 10 into the drill hole. The heavy wheel 10 moves downward under its own gravity, driving the third telescopic rod 8 to move downward, and driving the rotating shaft 9 to move downward. Since the telescopic damping of the third telescopic rod 8 is greater than that of the first telescopic rod 6 and the second telescopic rod 7, the first telescopic rod 6 and the second telescopic rod 7 first extend until the heavy wheel 10 comes into contact with the inclination of the drill hole. The heavy wheel 10 moves into the lower inclined drill hole and contacts the bottom wall of the drill hole. The heavy wheel 10 continues to roll downward, driving the third telescopic rod 8 to extend; when the heavy wheel 10 enters the lower drill hole, it drives the third telescopic rod 8 to incline. The third telescopic rod 8 drives the rotating shaft 9 to rotate through the connecting rod 92. The rotating shaft 9 drives the second bevel gear 91 to rotate. The second bevel gear 91 drives the second telescopic rod 7 to rotate. The second telescopic rod 7 drives the lead screw 22 to rotate. The rotation of the lead screw 22 drives the moving block 23 to move. The moving block 23 drives the display component 5 to move, thereby displaying the inclination angle through the display component 5.

[0047] Refer to Figure 1 and Figure 2 , the positioning component 1 includes a positioning plate 11, and the positioning plate 11 is horizontally arranged; the rotating plate 3 is arranged on the positioning plate 11 and is rotatably connected to the positioning plate 11; the operation box 2 is arranged on the rotating plate 3. Since the angle of change of the drilling direction is uncertain, the setting of the rotating plate 3 enables the operation box 2 to rotate relative to the positioning plate 11, so as to flexibly adjust the position and angle of the operation box 2 to meet the requirements of measuring the inclination of drill holes in different orientations.

[0048] Before measurement, first place the positioning plate 11 around the drill hole, align the first telescopic rod 6 with the drill hole, and make the heavy wheel 10 enter the drill hole. Observe the display component 5. If there is a change in the display component 5, it proves that the heavy wheel 10 directly passes from the upper section of the drill hole through the inclination into the lower section of the drill hole. At this time, directly read the display component 5; if there is no change in the display component 5, it proves that the heavy wheel 10 is stuck at the inclination between the upper and lower sections of the drill hole. At this time, rotate the rotating plate 3 until the heavy wheel 10 can enter the lower section of the drill hole. At this time, the heavy wheel 10 drives the third telescopic rod 8 to extend, and the display component 5 will display the inclination angle.

[0049] Refer to Figure 1 and Figure 2 , the sliding component 4 is slidably arranged on the rotating plate 3 in the horizontal direction; the operation box 2 is rotatably arranged on the sliding component 4. The sliding component 4 enables the operation box 2 to slide horizontally on the rotating plate 3, so as to realize the measurement of the inclination of drill holes at different positions; at the same time, the operation box 2 can rotate around the sliding component 4, further improving the flexibility and adaptability of the device, and being able to better meet the use requirements under different working conditions.

[0050] Before measurement, if the length direction of the upper section of the drill hole is vertical, the weight wheel 10 can be placed directly; if the length direction of the upper section of the drill hole is inclined, when the weight wheel 10 enters the upper section of the drill hole, it will drive the first telescopic rod 6 and the second telescopic rod 7 to incline, and then drive the operation box 2 to incline, and drive the sliding component 4 to slide to a suitable position, so that the weight wheel 10 can smoothly slide into the upper section of the drill hole.

[0051] Refer to Figure 1 and Figure 2 , a chute 31 is formed in the rotating plate 3. The length direction of the chute 31 is horizontal, and the depth direction of the chute 31 is vertical. The chute 31 penetrates the rotating plate 3 along the vertical direction, and a slider 41 is slidably arranged in the chute 31 along its length direction. The design of the chute 31 enables the slider 41 to slide freely in the horizontal direction, thereby realizing the position adjustment of the operation box 2 in the horizontal direction, and enabling the device to cope with the working condition of the inclined upper section of the drill hole, increasing the applicable range.

[0052] Refer to Figure 1 and Figure 2 , the longitudinal section of the chute 31 is T-shaped, and the longitudinal section of the slider 41 is also T-shaped, and the size is adapted to the size of the chute 31. The design of the T-shaped chute 31 and the T-shaped slider 41 enables the slider 41 to slide stably in the chute 31, preventing the slider 41 from coming out of the chute 31, and improving the reliability and stability of the device. A slide plate 42 is fixedly connected to the top of the slider 41, and the cross-sectional dimension of the slide plate 42 is larger than the cross-sectional dimension of the slider 41. The bottom surfaces on both sides of the slide plate 42 are in contact with the top surface of the rotating plate 3.

[0053] Refer to Figure 1 and Figure 2 , a first communication groove 421 is formed in the slide plate 42; a second communication groove 411 is formed in the slider 41; the first communication groove 421 penetrates the slide plate 42 along the vertical direction, the second communication groove 411 penetrates the slider 41 along the vertical direction, and the first communication groove 421 and the second communication groove 411 communicate with each other; both the first telescopic rod 6 and the second telescopic rod 7 can pass through the first communication groove 421. The slide plate 42 fixedly connected to the top of the slider 41 can effectively increase the contact area between the slider 41 and the rotating plate 3, improving the stability and reliability during the sliding process. At the same time, the bottom surfaces on both sides of the slide plate 42 are in contact with the top surface of the rotating plate 3, which can prevent the slider 41 from shaking or shifting in the chute 31, ensuring the precise movement and positioning of the operation box 2 in the horizontal direction.

[0054] Refer to Figure 1 and Figure 2, on both sides of the top of the skateboard 42, a support plate 43 is fixedly connected. The support plate 43 is vertically arranged. The operation box 2 is arranged between the two support plates 43. Both sides of the operation box 2 are rotatably connected to a support plate 43. The rotation axis direction of the operation box 2 is parallel to the axis direction of the rotating shaft 9. The support plates 43 fixed on both sides of the top of the skateboard 42 can effectively stabilize the position of the operation box 2 and ensure the stability of the operation box 2 during use. At the same time, the rotational connection between the operation box 2 and the support plate 43 enables the operation box 2 to freely rotate on the horizontal plane, facilitating rotation along with the rotation of the first telescopic rod 6.

[0055] Refer to Figure 2 and Figure 5 , at the bottom end of the outer wall of the second telescopic rod 7, a rotating ring 72 is fixedly sleeved. At the bottom end of the inner wall of the first telescopic rod 6, an annular rotating groove 62 is opened. The size of the rotating groove 62 is adapted to the size of the rotating ring 72. The rotating ring 72 is rotatably arranged in the rotating groove 62. It can ensure the stable rotation of the second telescopic rod 7 relative to the first telescopic rod 6, thereby guaranteeing the smoothness and accuracy of the drilling inclination measuring device during operation. The design of the rotating ring 72 and the rotating groove 62 effectively reduces the friction force and extends the service life of the equipment.

[0056] Refer to Figure 2 and Figure 3 , the display component 5 includes a moving rod 51 and a display board 52. The moving rod 51 is horizontally arranged. One end of the moving rod 51 is located inside the operation box 2 and is fixedly connected to the moving block 23; the other end of the moving rod 51 is located outside the operation box 2 and is fixedly connected to the display board 52. The display board 52 is vertically arranged and is attached to the outer side wall of the operation box 2. The moving rod 51 is fixedly connected to the moving block 23. When the screw rod 22 rotates to drive the moving block 23 to move up and down, the moving rod 51 also moves accordingly, thereby driving the display board 52 to move synchronously in the vertical direction. The display board 52 is closely attached to the outer side wall of the operation box 2, and the inclination angle information of the measured drilling can be obtained through the display board 52.

[0057] Refer to Figure 2 and Figure 3 , on the outer side wall of the operation box 2, a moving groove 24 is opened. The length direction of the moving groove 24 is the vertical direction. The size of the moving rod 51 is adapted to the size of the moving groove 24. The moving rod 51 is slidably arranged in the moving groove 24 in the vertical direction; on one side of the moving groove 24 on the outer side wall of the operation box 2, a scale 25 is provided. The length direction of the scale 25 is parallel to the length direction of the moving groove 24. The design of the moving groove 24 enables the moving rod 51 to slide smoothly in the vertical direction, thereby ensuring that the display board 52 accurately reflects the inclination angle of the drilling as the moving block 23 moves up and down. At the same time, the setting of the scale 25 further improves the measurement accuracy and facilitates the user to intuitively read and record data.

[0058] The implementation principle of a drilling inclination measuring device according to an embodiment of the present application is as follows:

[0059] This drilling inclination device is applied to measure the inclination angle between the upper section and the lower section in a drilling hole.

[0060] Before measurement, first place the positioning plate 11 around the drilling hole and align the first telescopic rod 6 with the drilling hole. If the length direction of the upper section of the drilling hole is vertical, just place the weight wheel 10; if the length direction of the upper section of the drilling hole is inclined, when the weight wheel 10 enters the upper section of the drilling hole, it will drive the first telescopic rod 6 and the second telescopic rod 7 to tilt, and then drive the operation box 2 to rotate to an inclined state, and drive the slider 41 and the sliding plate 42 to slide to appropriate positions, so that the weight wheel 10 can smoothly slide into the upper section of the drilling hole.

[0061] When the weight wheel 10 enters the drilling hole, after the weight wheel 10 moves downward for a preset time, observe the display board 52. If the height of the display board 52 changes, it proves that the weight wheel 10 directly passes from the upper section of the drilling hole through the inclination angle into the lower section of the drilling hole. At this time, directly read the scale corresponding to the display board 52; if the height of the display board 52 does not change, it proves that the weight wheel 10 is stuck at the inclination angle between the upper section and the lower section of the drilling hole. At this time, rotate the rotating plate 3 until it rotates to the position where the weight wheel 10 can pass through the inclination angle and enter the lower section of the drilling hole. At this time, the weight wheel 10 drives the third telescopic rod 8 to extend. Through the transmission of the second telescopic rod 7, the lead screw 22 and the moving block 23, the display board 52 is driven to move, and the scale corresponding to the display board 52 is the corresponding data of the inclination angle.

[0062] The movement principle of the weight wheel 10 in the drilling hole is as follows: When the weight wheel 10 is placed in the drilling hole, the weight wheel 10 moves downward under its own gravity, driving the third telescopic rod 8 to move downward and driving the rotating shaft 9 to move downward. Since the telescopic damping of the third telescopic rod 8 is greater than that of the first telescopic rod 6 and the second telescopic rod 7, the first telescopic rod 6 and the second telescopic rod 7 first extend until the weight wheel 10 contacts the inclination angle of the drilling hole. The weight wheel 10 moves from the upper section of the drilling hole to the inclined lower section of the drilling hole and contacts the bottom wall of the lower section of the drilling hole. The weight wheel 10 continues to roll downward in the lower section of the drilling hole, driving the third telescopic rod 8 to also enter the lower section of the drilling hole and extend; when the weight wheel 10 enters the lower drilling hole, it drives the third telescopic rod 8 to tilt. The third telescopic rod 8 drives the rotating shaft 9 to rotate through the connecting rod 92. The rotating shaft 9 drives the second bevel gear 91 to rotate. The second bevel gear 91 drives the second telescopic rod 7 to rotate. The second telescopic rod 7 drives the lead screw 22 to rotate. The lead screw 22 rotates to drive the moving block 23 to move. The moving block 23 drives the moving rod 51 to move. The moving rod 51 drives the display board 52 to move, so as to move the display board 52 to the corresponding scale.

[0063] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
