Description

[0001] The present application relates to the field of measurement technology, and particularly to an inclinometer. Background Art

[0002] In the angle of repose test of cohesionless soil, numerous granular cohesionless soils are poured onto a horizontal plane and piled up into a cone. The internal angle formed by the surface of the pile and the horizontal plane is the angle of slope. The angle of slope result of cohesionless soil affects many works such as the design and construction of foundation pits and slopes. In the current angle of slope testing device, an operator manually turns a crank handle to drive a funnel to move upward, so that the cohesionless soil in the funnel falls into a tray. By raising the height of the funnel, the test sample is poured to form a cone and the angle of slope is measured. In the way of forming an angle of slope by flowing the cohesionless soil from the funnel into the tray, the soil material will flow out quickly due to the action of gravity, resulting in uneven accumulation. In a short time, more soil material is concentrated in a certain area of the tray, making the angle of slope in this area too large and significantly different from other parts, thus affecting the accuracy and stability of the angle of slope.

Detailed implementation manners

[0025] To make the above objects, features, and advantages of the present application more obvious and understandable, the following will describe the detailed implementation manners of the present application with reference to the accompanying drawings. Many specific details are set forth in the following description to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0026] Please refer to Figure 1 , an embodiment of the present application provides an inclinometer 100, which includes a support base 1, an angle measuring device 2, a receiving device 3, a lifting device 4, and a leveling device 5.

[0027] Please refer to Figure 1, in some embodiments, the angle measuring device 2 includes a height ranging module 21 and a slope angle calculation module both disposed on the support base 1, and the slope angle calculation module is electrically connected to the height ranging module 21. The receiving device 3 is disposed on the support base 1. The receiving device 3 includes a tray 31, and along the height direction of the support base 1, a guiding member 32 protrudes vertically from the tray 31. The lifting device 4 includes a rotary driver, a traction assembly, and a rope. The rotary driver is disposed on the support base 1, the traction assembly is connected to the output end of the rotary driver, one end of the rope is wound around the traction assembly, and the other end of the rope is connected to the top end of the guiding member 32. It can be understood that the user can use a pouring tool with a narrow outlet, such as a spoon, to scoop a small amount of soil material, and make the outlet of the spoon contact the guiding member 32, so that the soil material slowly and evenly flows along the guiding member 32 to the tray 31. By the combined use of the pouring tool and the guiding member 32, it is possible to facilitate the control of the pouring speed and flow rate of the soil material, to achieve pouring the soil material in small batches, to reduce the splashing and dispersion of the soil material during the outflow process, and to enable the soil material to evenly fall on each area of the disc, so that the formed slope angle is more uniform and stable. When the bottom surface of the slope formed by the soil material completely coincides with the disk surface of the tray 31, the slope angle of the slope body at this time is the target slope angle. Turn on the rotary driver, so that the rotary driver drives the traction assembly to drive the rope to rise. The rope is connected to the guiding member 32, and then the tray 31 is raised to the test height of the angle measuring device 2. The height ranging module 21 measures the height difference between the top end and the bottom surface of the slope body, and transmits the height difference data to the slope angle calculation module. The slope angle calculation module calculates the slope angle according to the radial radius of the bottom surface of the tray 31 and the height difference. By providing the rotary driver, a more stable and uniform lifting force can be provided, the movement speed and the final stop position of the tray 31 can be more accurately controlled, the movement of the tray 31 can be made more stable, and the position deviation caused by the artificial jitter or instability of a hand-operated device such as a rocker can be reduced. In addition, the rotary driver can ensure a greater power output, can be applied to a heavier tray 31 and slope body load, and can ensure the sustainable progress of the lifting movement.

[0028] Please refer to Figure 1, in some embodiments, the tray 31 is a disc, and the guiding member 32 protrudes from the center of the disc. The disc shape has uniformity in terms of force application. When cohesionless soil is poured onto the disc to form a slope body, the soil material can be more evenly distributed on the entire surface of the disc, which helps to form a stable and regular slope angle. Compared with other shapes, such as a square or polygonal tray 31, the edge transition of the disc is smoother, reducing the uneven accumulation and concentration that may occur at the corners. Setting the guiding member 32 at the center of the disc can ensure the stability of the lifting or lowering action to the greatest extent. During the operation, applying force from the center can keep the tray 31 in a horizontal state when it rises or falls, avoiding tilting and measurement errors caused by eccentric force. Moreover, the symmetry of the disc makes measurement and data analysis simpler and more accurate. Since the characteristics are the same in all directions, consistent and reliable results can be obtained regardless of the measurement and observation angle.

[0029] In some embodiments, for cohesionless soil with a particle size less than 2 mm, a tray 31 with a diameter of 80 mm to 120 mm is used. For cohesionless soil with a particle size less than 5 mm, a tray 31 with a diameter of 180 mm to 220 mm is used. The height of the guiding member 32 is 12 cm to 14 cm. Setting the height of the guiding member 32 within this range can ensure that the bottom surface of the formed slope body completely coincides with the tray 31, and the top end of the guiding member 32 is exposed outside the slope body, thus not interfering with the traction of the rope on the guiding member 32. The guiding member 32 can be a guiding rod or a guiding bar, etc.

[0030] Exemplarily, the diameter of the tray 31 can be any point value within the above range, for example, it can be 80 mm, 85 mm, 90 mm, 95 mm, 100 mm, 105 mm, 110 mm, 115 mm, 120 mm, etc. Or, the diameter of the tray 31 can be 180 mm, 185 mm, 190 mm, 195 mm, 200 mm, 205 mm, 210 mm, 215 mm, 220 mm, etc. The height of the guiding member 32 can be any point value within the above range, for example, it can be 12 cm, 12.5 cm, 13 cm, 13.5 cm, 14 cm, etc.

[0031] Please refer to Figure 2 , in some embodiments, the receiving device 3 further includes a trough body 33. The trough body 33 is provided with a receiving cavity 331 and an opening 332 communicating with the receiving cavity 331. The tray 31 is located in the receiving cavity 331, and the top end of the guiding member 32 faces the opening 332. Please refer to Figure 3, the height of the guiding member 32 is less than or equal to the depth of the groove body 33. By providing the groove body 33, the accommodating cavity 331 of the groove body 33 can be used to hold water, and thus can be used for the slope angle test of cohesionless soil in the underwater state. Making the height of the guiding member 32 less than or equal to the depth of the groove body 33 can ensure that the water can completely immerse the guiding member 32, and thus can ensure that the slope body can be completely immersed in water.

[0032] The specific process of the underwater slope angle test is as follows: When the soil material forms a slope body on the tray 31 and stabilizes, first let the lifting device 4 lift the tray 31 away from the groove body 33, and inject enough water into the accommodating cavity 331 of the groove body 33 to ensure that the guiding member 32 can be completely immersed. Then let the lifting device 4 immerse the tray 31 into the groove body 33, and stop descending after the slope body is completely immersed in water. Wait until the soil material is fully saturated with water until no bubbles rise. Then let the lifting device 4 lift the tray 31 until the slope body reaches the test position of the angle measuring device 2, and perform the slope angle test through the angle measuring device 2.

[0033] Please refer to Figure 4 , in some embodiments, the groove body 33 is a cylindrical groove body 33, and the tray 31 is concentrically arranged with the groove body 33. Such an arrangement is beneficial to maintaining the stability of the slope body underwater. The concentric arrangement of the tray 31 and the groove body 33 can reduce the generation of vortices and turbulence, avoid the inclination of the tray 31 caused by water flow resistance, and avoid the scouring and damage to the slope body. Please refer to Figure 1 and Figure 4 , in some embodiments, the guiding member 32, the tray 31 and the groove body 33 are all concentrically arranged. It can further maintain the stability of the underwater structure of the slope body.

[0034] Please refer to Figure 2, in some embodiments, the support base 1 includes a bottom plate 11, a support rod 12, and an extension rod 13. The bottom plate 11 includes opposite first and second sides 111 and 112. Along the height direction of the support base 1, the bottom end of the support rod 12 is connected to the first side 111, the top end of the support rod 12 is connected to one end of the extension rod 13 along its own length direction, and the other end of the extension rod 13 along its own length direction extends away from the support rod 12 and towards the second side 112. The angle measuring device 2 is provided on the support rod 12, the tray 31 is provided on the bottom plate 11, and the lifting device 4 is provided on the extension rod 13. By providing the bottom plate 11, the support rod 12, and the extension rod 13, the overall structure of the support base 1 can be made more stable and balanced. When a relatively heavy slope is formed on the tray 31, when the lifting device 4 is working, the force can be effectively dispersed, reducing the shaking of the support base 1. By setting the angle measuring device 2 on the support rod 12, its measurement position can be relatively fixed and accurate, without being interfered by the movement of other components. By setting the tray 31 on the bottom plate 11, the bottom plate 11 can provide a relatively large support area, and can stably support the tray 31 and the slope. By setting the lifting device 4 on the extension rod 13, away from the bottom plate 11 and the tray 31, interference with the slope on the tray 31 during the lifting process can be avoided, and the extended design of the extension rod 13 can also provide sufficient operating space for the lifting device 4, facilitating its lifting operation.

[0035] Please refer to Figure 2 and Figure 3 , in some embodiments, the leveling device 5 includes a plurality of leveling screws 51. The support rod 12 is provided with a cavity filled with liquid, and there is a bubble inside the liquid. The bottom plate 11 is provided with a plurality of screw holes, and the plurality of leveling screws 51 are respectively connected to the plurality of screw holes in one-to-one correspondence. Thus, by rotating the leveling screws 51, the bottom plate 11 can be raised or lowered, and the height of the bottom plate 11 can be adjusted. By observing the position of the bubble, it can be determined whether the bottom plate 11 is kept horizontal. When the bubble remains centered in the liquid, it indicates that the bottom plate 11 is kept horizontal.

[0036] In some embodiments, the plurality of screw holes and the plurality of leveling screws 51 are arranged at the four corners or the edge positions of the bottom plate 11.

[0037] Please refer to Figure 2 , in some embodiments, both the height ranging module 21 and the slope angle calculation module are provided on the support rod 12 of the support base 1.

[0038] In some embodiments, the height ranging module 21 can be a laser ranging module, an infrared ranging module, an ultrasonic ranging module, etc.

[0039] In some embodiments, the height ranging module 21 includes a laser emitter, a laser receiver, and a laser signal processor, all of which are disposed on the support base 1. The laser signal processor is electrically connected to the laser emitter, the laser receiver, and the slope angle calculation module. It can be understood that the laser emitter is used to emit laser light, the laser receiver is used to receive the laser light reflected back by the slope body, and the laser signal processor is used to process the received laser signal, calculate the height difference between the top and the bottom of the slope body, and send the distance information of the height difference to the slope angle calculation module. The slope angle calculation module calculates the slope angle based on the radius of the tray 31 and the height difference. The laser ranging module has strong anti-interference capabilities against ambient light and electromagnetic interference, and due to the characteristics of the straight-line propagation of the laser beam and the high-frequency measurement, the laser angle measuring device 2 can provide stable and accurate measurement results under various environmental conditions.

[0040] Please refer to Figure 2 , in some embodiments, the angle measuring device 2 further includes a display module 22, and the display module 22 is also disposed on the support rod 12 of the support base 1. The display module 22 includes a display screen and a controller, and the controller is electrically connected to the display screen and the slope angle calculation module. The slope angle calculation module sends the slope angle data to the controller, and the controller converts the data signal into a visual image or text and causes the display screen to display it.

[0041] Please refer to Figure 2 , and the specific structure of the lifting device 4 will be introduced below.

[0042] In some embodiments, the rotary drive can be a rotary motor or a rotary motor.

[0043] In some embodiments, the traction assembly can include components such as pulleys, winches, or sprockets that can be used to traction ropes.

[0044] In some embodiments, the traction assembly includes a pulley, and the pulley is connected to the output end of the rotary drive. One end of the rope is wound around the outer peripheral surface of the pulley. The pulley has a simple structure, low manufacturing and installation costs, and small friction, which can reduce the friction force on the rope, and it occupies a small space, has a compact structure, and is convenient for installation and arrangement.

[0045] In some embodiments, the lifting device 4 further includes a transmission assembly and a mounting table. The mounting table is disposed on the support base 1. The mounting table is provided with a mounting hole. The rotary drive and the traction assembly are both located outside the mounting table. The transmission assembly is rotatably connected to the mounting hole and is simultaneously transmission-connected to the output end of the rotary drive and the traction assembly. By adding a transmission assembly, the transmission ratio can be increased and the transmission direction can be changed, converting the horizontal rotational movement of the rotary drive into a vertical or other required direction of movement, thereby adapting to the requirements of different installation or working spaces.

[0046] In some embodiments, the transmission assembly may be a worm and worm gear transmission assembly or a synchronous belt and pulley transmission assembly, etc. The embodiments of the present application do not limit the specific component composition of the transmission assembly, and any transmission assembly that can achieve the transmission between the rotary drive and the traction assembly is within the protection scope of the embodiments of the present application.

[0047] In some embodiments, the transmission assembly includes a worm, a worm gear, and a rotating shaft. The mounting hole includes a first mounting hole that penetrates the mounting table in a first direction and a second mounting hole that penetrates the mounting table in a second direction. The first direction and the second direction intersect. Along the height direction of the support base 1, the first mounting hole is located at the bottom of the second mounting hole. The worm is rotatably connected to the first mounting hole, and the end of the worm outside the mounting table is connected to the output end of the rotary drive. The rotating shaft is rotatably connected to the second mounting hole, and the end of the rotating shaft outside the mounting table is connected to the traction assembly. The worm gear is sleeved on the rotating shaft, and the worm gear is in threaded engagement with the worm. It can be understood that the first direction coincides with the extending direction of the output end of the rotary drive. The worm and worm gear transmission has a large transmission ratio, which means that the high-speed rotation of the output end of the rotary drive can be converted into the low-speed and large-torque movement of the pulley and the rope, so as to more precisely control the traction speed and force of the rope. When slowly and steadily lifting the tray 31, a finer and more stable lifting operation can be provided. The worm and worm gear transmission has a self-locking characteristic. When the worm stops rotating, the worm gear cannot rotate by itself, which can effectively prevent the load from reversing, thereby improving the safety and stability of the lifting device 4. After lifting the tray 31, even if the rotary drive is powered off, it can ensure that the tray 31 will not accidentally fall. In addition, the worm and worm gear transmission can play a certain buffering and shock-absorbing role. It can reduce the impact on the traction assembly and the rope when the rotary drive starts and stops, and extend the service life of the lifting device 4.
