[0002] In land engineering construction, slope measurement is a crucial link, and various slope measuring devices are usually used to measure the slope. Currently, handheld slope measuring devices are mostly used for measurement. The measuring device is placed on the slope surface, and the measurement result is obtained by observing the changes of the pointer on the angle disk of the device.

[0003] At present, slope measurement mainly relies on a single-direction slope meter. This type of instrument faces many limitations when used. For example, it needs to be precisely aligned with the slope inclination angle, and is easily affected by the operator's placement, resulting in measurement errors. In addition, due to its small and portable structure design, it is only suitable for small-scale point measurement, and there is an inaccurate measurement result, which makes it difficult to meet the needs of large-scale land engineering projects for continuous and accurate measurement of the overall slope. Therefore, it is particularly urgent to develop a slope measurement device that can be fully adaptive and can measure efficiently over a large range. Summary of the invention

A slide groove is opened inside the guide rail plate, and scale lines are engraved on the front and rear sides of the guide rail plate.

[0013] Furthermore, a pad is fixedly provided on one side of the upper surface of the movable bottom plate close to the connecting plate a and on one side of the upper surface of the fixed bottom plate close to the connecting plate a, and the pad is located directly below the slide rail, and the upper surface is in contact with the bottom surface of the slide rail.

[0017] Furthermore, a controller is installed on the moving base on the right side of the support plate, the controller has a built-in microprocessor, and a display screen is installed on the front side of the controller.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention can adapt to various slopes without the need to accurately align the slope inclination angle, reducing the influence of the operator's placement on the measurement results and improving the measurement accuracy. At the same time, the device as a whole adopts a retractable and foldable structure, which is convenient to carry and use, and can increase the contact area with the slope after unfolding, which can extend the measurement length of the slope and reduce the measurement error. It is suitable for continuous and accurate measurement of the overall slope of large-scale land engineering projects.

[0020] 2. The present invention can measure the slope of the slope through the measurement mechanism and obtain accurate measurement results. When the device is placed on the slope, the measuring ball will slide down the slide rail under the action of gravity, and the speed sensor will record the moving speed of the ball in real time, and then indirectly measure the slope by measuring the speed at which the ball reaches the bottom position. By measuring the motion parameters of the ball to indirectly measure the slope, dynamic measurement is achieved, which improves the accuracy and flexibility of the measurement.

[0021] 3. The present invention can adjust the telescopic length of the movable base, so that the telescopic base can be adjusted to adapt to slopes of different lengths, and the device can be stably fixed on the slope through the positioning component to ensure that the device will not move or tilt during the measurement process. The flexibility and accuracy of the measurement are improved, so that the device can be applied to the measurement of slopes of various lengths. In addition, the stability and adjustability of the telescopic base also provide convenience for measurement and are easy to carry. The operator can adjust the base length according to actual needs and ensure the stability of the device during the measurement process.

[0022] 4. The self-locking mechanism can keep the device stable after being adjusted to the appropriate angle, ensure the stability of the device, and prevent it from rotating on its own. When the angle of the measuring mechanism needs to be adjusted, the self-locking mechanism can be unlocked by operating the pressure plate, pressing the pressure plate downward, and the movable chuck is driven downward by the pressure plate. At this time, the movable chuck is separated from the fixed chuck by the action of the spring, allowing the supporting shaft to rotate freely. Then the measuring mechanism rotates to an angle position parallel to the slope under the action of gravity. When the measuring mechanism is adjusted to the appropriate angle, release the pressure plate, use the elasticity of the spring to move the pressure plate upward to reset, drive the movable chuck upward and engage with the micro-teeth of the fixed chuck, thereby achieving self-locking.

[0023] 5. The fixed ball seat provides a stable support point for the measuring ball, which is used to place the measuring ball at the beginning of the measurement to ensure the stability of the measuring ball. The set electromagnet can generate magnetism, and then use the magnetism to adsorb and fix the measuring ball through the fixed ball seat, so that the measuring ball can be stably fixed in the groove inside the fixed ball seat. By controlling the on and off of the electromagnet, the adsorption and release of the measuring ball can be achieved.

[0024] 6. The slide rail adopts a split structural design, and is fixedly connected by blocks and slots, which not only ensures the stability between the guide rail plates, but also facilitates assembly and disassembly. The left and right ends of the slide rail are fixedly connected to the left fixed frame and the fixed ball seat through blocks and slots respectively. This connection method ensures the stability and alignment accuracy between the slide rail and the fixed frame, providing a reliable basis for measurement. A slide groove is opened inside the guide rail plate, which provides a guide path for the rolling of the measuring ball, ensuring that the measuring ball can slide in a straight line along the guide rail plate, and limiting the movement of the measuring ball to prevent the measuring ball from falling from the slide rail. There are scale lines engraved on both the front and back sides of the guide rail plate. The scale lines are used to accurately measure the sliding distance of the ball, and then the slope of the slope is indirectly calculated by measuring the speed of the ball when it slides to the end point.

[0025] 7. Magnets are embedded on the left and right sides of the central fixed base and the inner side of the movable base, and the magnetism of the two magnets is opposite. Since the magnetism of the two magnets is opposite, there will be attraction between them. The magnetic force can firmly adsorb the movable base to the central fixed base, ensuring that the telescopic base can be stably retracted when not in use and will not unfold by itself, which not only reduces the storage space of the device, but also makes it more convenient to carry.

[0026] 8. The positioning component provides a stable positioning and support function for the device, which can ensure that the device is firmly fixed on the slope during measurement, ensuring the accuracy and reliability of the measurement. At the same time, its foldable and expandable design also makes the measuring device more portable and flexible, and suitable for various complex measurement environments.

DETAILED DESCRIPTION

[0040] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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 making creative work are within the scope of protection of the present invention.

[0041] Example:

[0042] like Figures 1 to 11 As shown, a land engineering slope measuring device comprises a telescopic base 3 and a measuring mechanism 1. The measuring mechanism 1 is arranged on the upper side of the telescopic base 3. A supporting shaft 7 is fixedly provided on the right side of the bottom of the measuring mechanism 1. The supporting shaft 7 is rotatably connected to the telescopic base 3 through an axle seat 8. A self-locking mechanism 4 is provided on the left side of the ring surface of the supporting shaft 7. This design solves the problem that the existing slope measurement mainly relies on a single-direction slope meter. Such instruments face many limitations when in use, such as the need to accurately align the slope inclination angle, and are easily affected by the operator's placement position, resulting in measurement errors; in addition, since its structural design tends to be small and portable, it is only suitable for small-range point measurement, and there is a problem of inaccurate measurement results, which makes it difficult to meet the needs of large-scale land engineering projects for continuous and accurate measurement of the overall slope.

[0043] The measuring mechanism 1 includes a support seat 11, a fixed frame 12, a slide rail 13, a speed sensor 14 and a measuring ball 15. The support seat 11 is arranged on the upper side of the telescopic base 3, and the support seat 11 is rotatably connected to the telescopic base 3 through a supporting shaft 7. The left and right ends of the upper side of the support seat 11 are fixedly provided with a fixed frame 12, and a slide rail 13 is fixedly connected between the two sets of fixed frames 12. A movable measuring ball 15 is placed on the slide rail 13. The left side of the upper end surface of the support seat 11 is equipped with a speed sensor 14, and the speed sensor 14 is located in front of the slide rail 13. The measuring mechanism 1 can measure the slope of the slope and obtain an accurate measurement result. When the device is placed on the slope, the measuring ball 15 will slide down along the slide rail 13 under the action of gravity, and the speed sensor 14 will record the moving speed of the ball in real time, and then indirectly measure the slope by measuring the speed at which the ball 15 reaches the bottom position. By measuring the motion parameters of the ball 15 to indirectly measure the slope, dynamic measurement is achieved, and the accuracy and flexibility of measurement are improved.

[0044] The telescopic base 3 includes a movable base 31, a connecting plate b32, a central fixed base 33, a positioning assembly 34 and a telescopic slot b36. The movable base 31 is arranged at intervals on both sides of the central fixed base 33. The connecting plates b32 are fixedly connected to the left and right ends of the central fixed base 33. The two sets of movable bases 31 are provided with telescopic slots b36 on one side facing the central fixed base 33, and the connecting plates b32 are inserted into the telescopic slots b36. The bottom of each set of movable bases 31 is provided with a positioning assembly 34 near the outer corner. By adjusting the telescopic length of the movable base 31, the telescopic base 3 can be adjusted telescopically, and can adapt to slopes of different lengths. The positioning assembly 34 can stably fix the device on the slope to ensure that the device will not move or tilt during the measurement process. This improves the flexibility and accuracy of the measurement, so that the device can be applied to slope measurements of various lengths. In addition, the stability and adjustability of the telescopic base 3 also provide convenience for measurement and are convenient to carry. The operator can adjust the base length according to actual needs and ensure the stability of the device during the measurement process.

[0045] The self-locking mechanism 4 includes a fixed chuck 41, a movable chuck 42, a pressure plate 43, a spring piece 44 and a positioning plate 45. The fixed chuck 41 is fixedly sleeved on the support shaft 7, and the movable chuck is movably sleeved on the support shaft 7 and is located at the lower side of the fixed chuck 41. Micro-teeth are arranged on the opposite surfaces of the movable chuck and the fixed chuck 41. The movable chuck and the fixed chuck 41 are connected by micro-teeth engagement. The left side of the ring surface of the movable chuck 42 is fixedly connected with a pressure plate 43. The left end of the pressure plate 43 is fixedly connected to the movable base 31 through a positioning plate 45. An arc-shaped spring piece 44 is fixedly arranged between the bottom surface of the pressure plate 43 and the positioning plate 45. The self-locking mechanism 4 can keep the device stable after being adjusted to a suitable angle, ensure the stability of the device, and prevent it from rotating by itself. When the angle of the measuring mechanism 1 needs to be adjusted, the self-locking mechanism 4 can be unlocked by operating the pressing plate 43, pressing the pressing plate 43 downward, and the movable chuck 42 is driven downward by the pressing plate 43. At this time, the movable chuck 42 is separated from the fixed chuck 41 under the action of the spring 44, allowing the supporting shaft 7 to rotate freely. Then the measuring mechanism 1 rotates to an angle position parallel to the slope under the action of gravity. When the measuring mechanism 1 is adjusted to a suitable angle, the pressing plate 43 is released, and the elasticity of the spring 44 is used to move the pressing plate 43 upward to reset, driving the movable chuck 42 to move upward and engage with the micro-teeth of the fixed chuck 41, thereby achieving self-locking.

[0046] The design can realize the locking and unlocking of the self-locking mechanism 4 by simply operating the pressure plate 43. The micro-tooth design makes the combination between the chucks more compact and stable, effectively preventing accidental movement during the measurement process, and having good stability. In addition, the self-locking mechanism 4 can adapt to the adjustment requirements of different angles, providing greater flexibility and strong adaptability for slope measurement.

[0047] The support base 11 is composed of a movable bottom plate 111, a telescopic slot a112, a connecting plate a113 and a fixed bottom plate 114. The movable bottom plate 111 is arranged on the left side of the fixed bottom plate 114. The fixed bottom plate 114 is fixedly connected to the support shaft 7. A connecting plate a113 is fixedly arranged on the left side of the fixed bottom plate 114. A telescopic slot a112 is arranged inside the right end surface of the movable bottom plate 111. The connecting plate a113 is inserted into the telescopic slot a112 and is movably connected to the movable bottom plate 111. Through the coordinated connection between the movable bottom plate 111, the telescopic slot a112, the connecting plate a113 and the fixed bottom plate 114, the support base 11 can be telescopically adjusted, so that the support base 11 can be telescopically extended with the device as a whole, which is convenient for carrying and use.

[0048] A fixed ball seat 16 is fixed on the left end surface of the right fixed frame 12, an electromagnet 17 is installed on the right end surface of the fixed frame 12, and a buffer seat 18 made of rubber material is arranged on the right end surface of the left fixed frame 12. A groove for accommodating the measuring ball 15 is provided on the opposite surface of the buffer seat 18 and the fixed ball seat 16. The fixed ball seat 16 provides a stable support point for the measuring ball 15, which is used to place the measuring ball 15 at the beginning of the measurement to ensure the stability of the measuring ball 15. The set electromagnet 17 can generate magnetism, and then use the magnetism to absorb and fix the measuring ball 15 through the fixed ball seat 16, so that the measuring ball 15 can be stably fixed in the groove inside the fixed ball seat 16. By controlling the power on and off of the electromagnet 17, the absorption and release of the measuring ball 15 can be achieved. At the beginning of the measurement, the electromagnet 17 is energized to absorb the ball to prevent it from sliding down; when the measurement is ready, the electromagnet 17 is de-energized to release the ball and make it slide down along the slide rail 13. The rubber buffer seat 18 has good elasticity and buffering performance, and can effectively absorb the impact force when the measuring ball 15 slides down to the end point, preventing the ball from rebounding or jumping out of the slide rail 13, thereby improving the safety of the measurement.

[0049] The slide rail 13 is composed of two groups of guide rail plates 131, and the two groups of guide rail plates 131 are fixedly connected by means of a block 134 and a slot 135. The slide rail 13 adopts a split structure design, and is fixedly connected by means of the block 134 and the slot 135, which not only ensures the stability between the guide rail plates 131, but also facilitates assembly and disassembly. The left and right ends of the slide rail 13 are respectively fixedly connected to the left fixed frame 12 and the fixed ball seat 16 through the block 134 and the slot 135. This connection method ensures the stability and alignment accuracy between the slide rail 13 and the fixed frame 12, and provides a reliable basis for measurement. A slide groove 132 is provided inside the guide rail plate 131, and the slide groove 132 provides a guide path for the rolling of the measuring ball 15, ensuring that the measuring ball 15 can slide linearly along the guide rail plate 131, and plays a role in limiting the movement of the measuring ball 15, so as to prevent the measuring ball 15 from falling off the slide rail 13. The guide plate 131 is provided with scale lines 133 on both the front and rear sides. The scale lines 133 are used to accurately measure the sliding distance of the ball 15, and then the slope of the slope is indirectly calculated by measuring the speed of the ball 15 when it slides to the end point.

[0050] A pad 115 is fixedly provided on one side of the upper surface of the movable bottom plate 111 close to the connecting plate a113 and on one side of the upper surface of the fixed bottom plate 114 close to the connecting plate a113, and the pad 115 is located directly below the slide rail 13, and the upper surface is in contact with the bottom surface of the slide rail 13. The pad 115 supports the slide rail 13 to ensure the stability of the slide rail 13 during installation and use. Since the upper surface of the pad 115 is in contact with the bottom surface of the slide rail 13, it can effectively prevent the slide rail 13 from shaking or shifting during use, thereby ensuring measurement accuracy.

[0051] Magnet pieces 35 are embedded on both sides of the central fixed base 33 and the inner side of the movable base 31, and the magnetism of the two magnet pieces 35 is opposite. Since the magnetism of the two magnet pieces 35 is opposite, an attraction is generated between the two, and the magnetic force can firmly adsorb the movable base 31 on the central fixed base 33, ensuring that the telescopic base 3 can be stably retracted when not in use and will not unfold by itself, which not only reduces the storage space of the device, but also makes it more convenient to carry.

[0052] The positioning assembly 34 includes an embedding groove 341, a leg 342, a receiving groove 343, an insertion rod 344 and a magnetic block 345. The embedding groove 341 is provided at the bottom of the movable base 31 near the outer corner. The embedding groove 341 is hingedly installed with a leg 342. The bottom of the leg 342 is provided with a receiving groove 343. The storage groove 343 is hingedly installed with an insertion rod 344. The inner side of the leg 342 and the inner side of the embedding groove 341 are both embedded with magnetic blocks 345, and the magnetism of the two magnetic blocks 345 is opposite. The positioning assembly 34 is provided to provide a stable positioning and support function for the device, which can ensure that the device is firmly fixed on the slope during measurement, ensuring the accuracy and reliability of the measurement. At the same time, its foldable and expandable design also makes the measuring device more portable and flexible, and suitable for various complex measurement environments.

[0053] A support plate 5 is fixedly arranged near the left end of the upper surface of the left movable base 31, and a plurality of groups of balls 6 are embedded on the top of the support plate 5, and the surface of the balls 6 is in contact with the bottom surface of the movable bottom plate 111. This design can provide stable support for the measuring mechanism 1 from the bottom to prevent the left end of the measuring mechanism 1 from falling and tilting, which not only improves the convenience and accuracy of the device, but also prolongs its service life. The balls 6 can significantly reduce the friction between the movable bottom plate 111 and the support plate 5, making the movement or adjustment of the movable bottom plate 111 easier and smoother.

[0054] A controller 2 is installed on the moving base on the right side of the support plate 5. The controller 2 has a built-in microprocessor and a display screen is installed on the front side of the controller 2. The controller 2 is responsible for processing data, executing instructions and controlling various functions of the measuring device. The slope of the slope can be calculated by measuring the speed of the ball 15. At the same time, the measurement structure can be displayed on the display screen, and the data reading is more intuitive.

[0055] The working principle of the land engineering slope measuring device is as follows: in actual use, the device is first placed on the slope to be measured, and the telescopic base 3 is unfolded, and the device is firmly fixed on the slope through the positioning component 34 to ensure that the device will not move or tilt during the measurement process. Press the plate 43 downward to unlock the self-locking mechanism 4 so that the supporting shaft 7 can rotate freely. Since the center of the measuring mechanism 1 is to the left, it will automatically rotate to a position angle corresponding to making it parallel to the slope under the action of gravity, and then release the pressing plate 43, and use the elasticity of the spring 44 to move the pressing plate 43 upward to reset, drive the movable chuck 42 to move up and engage with the micro-teeth of the fixed chuck 41, so as to achieve self-locking and fix the angle of the measuring mechanism 1. Then the measuring ball 15 is placed in the groove of the fixed ball seat 16 and fixed by adsorption by the electromagnet 17. Control the electromagnet 17 to cut off the power, release the measuring ball 15, and the ball slides down along the slide rail 13 under the action of gravity. The speed sensor 14 records the moving speed of the ball, and at the same time observes the scale of the ball on the slide rail 13 to record the sliding distance. The controller 2 receives the data from the speed sensor 14 and calculates the slope of the slope through the built-in microprocessor. The slope data is displayed in real time on the display screen for the operator to read, thereby realizing the slope measurement of the slope.

For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description.
