Description

Technical Field

[0001] This utility model relates to the technical field of slope measurement equipment, specifically a slope measuring instrument for power civil engineering. Background Technology

[0002] The slope meter is a surveying accessory product with slope measurement function. To measure the downslope angle, the slope meter uses the rear plane of the antenna (a) to rotate the scale wheel to center the bubble in the level tube. The degree indicated by the pointer on the scale is the downslope angle. The error requirement is ±0.5°.

[0003] According to the authorized Chinese patent announcement number CN 212058741 U, this utility model belongs to the field of measuring instrument technology, specifically a slope measuring instrument for power civil engineering. It includes a measuring instrument body, a horizontal plate, a bonding plate, and a protractor. A vertical rod is fixedly connected to the top of the other side of the measuring instrument body. Extension plates are movably connected to both ends of the vertical rod. A horizontal plate is movably connected to the top of the vertical rod. A rotating shaft is fixedly connected to one side of the horizontal plate. A bonding plate is movably connected to the periphery of the rotating shaft. A protractor is fixedly connected to the top of one side of the bonding plate. The scale of the protractor is pointed to by the scale rod of the fixed column, and that position indicates the slope degree. The bonding plate causes the protractor to fit against the slope, thus greatly ensuring that the sliding angle of the protractor is consistent with the slope. Therefore, the measuring mechanism facilitates slope measurement for users. Users can quickly measure the slope of different slopes simply by holding the connection between the horizontal plate and the vertical rod. This device has broad development prospects in the future.

[0004] The measuring instrument in the aforementioned patent still has certain shortcomings. In power civil engineering, slope meters are mostly used to measure the inclination angle of foundation pit slopes. However, in actual use, existing slope meters sometimes require workers to go up and down the foundation pit to measure, which is a lot of work and cumbersome to operate, and is not conducive to the rapid measurement of slope. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a slope measuring instrument for power civil engineering projects. It solves the problem that existing slope measuring instruments sometimes require workers to go up and down the foundation pit to measure slopes, which is labor-intensive, cumbersome, and not conducive to rapid slope measurement.

[0006] This utility model provides the following technical solution: a slope measuring instrument for power civil engineering, including a support base, an installation frame at the top of the support base, a slope measuring component on the installation frame, a measuring drive component on the side of the installation frame, and a level on the side of the top of the installation frame.

[0007] The slope measurement component includes a laser indicator disposed in the middle of the mounting frame. Two side connecting blocks are symmetrically arranged on both sides of the laser indicator. A fixed connecting plate is fixed to the outer side of the mounting frame. An annular limiting groove is formed on the inner wall of the fixed connecting plate. An angle plate is disposed on the side of the fixed connecting plate. A transmission rod is fixed to the side of the side connecting block. The end of the transmission rod rotatably passes through the side of the mounting frame. The end of the transmission rod passes through the middle of the fixed connecting plate and the angle plate in sequence. A fixing ring is fixed on the transmission rod. A pointer is vertically disposed on the side of the fixing ring. The end of the pointer extends into the annular limiting groove.

[0008] Preferred technical solution 1: The measurement drive assembly includes a drive chamber fixed to the side of the mounting frame, a large gear is rotatably arranged inside the drive chamber, a small gear is arranged on the side of the large gear, the central axis of the small gear is rotatably connected to the inner wall of the drive chamber and the outer wall of the mounting frame, and the large gear and the small gear are meshed and connected for transmission.

[0009] Preferred technical solution 2: A rotating connecting rod is fixed to the central shaft of the large gear, and the end of the rotating connecting rod rotatably passes through the mounting frame and is fixedly connected to the side connecting block. A rotating handle is provided on the outside of the drive compartment, and the end of the rotating handle rotatably passes through the drive compartment and is fixedly connected to the central shaft of the small gear.

[0010] Preferred technical solution 3: Both the fixed connecting plate and the angle plate have through holes in their middle parts.

[0011] This design allows the transmission rod to pass more easily through the middle of the fixed connecting plate and the angle plate.

[0012] Preferred technical solution four: The pointer is located on the side of the angle disk, and the end of the pointer extends into the annular limiting groove.

[0013] This design enables the pointer to better indicate the scale on the angle dial under the drive of the transmission rod.

[0014] Preferred technical solution five: The diameter of the large gear is larger than the diameter of the small gear.

[0015] This design allows the small gear to drive the large gear to rotate more slowly.

[0016] Compared with the prior art, this utility model provides a slope measuring instrument for power civil engineering, which has the following beneficial effects:

[0017] (1) This utility model has a slope measurement component and a measurement drive component set on the mounting frame. The laser indicator in the slope measurement component can rotate the small gear driven by the rotation of the handle, so that the small gear drives the large gear meshing with it to rotate, thereby driving the laser indicator to deflect. This allows the laser emitted by the laser indicator to be parallel or close to the slope surface. At this time, the pointer driven by the laser indicator through the transmission rod will rotate on the surface of the angle plate. The user only needs to measure the amplitude of the pointer rotation on the surface of the angle plate to obtain the slope of the slope. This makes the overall slope measurement faster and more convenient, and does not require workers to go up and down the slope, effectively reducing the intensity of their measurement work. The structure is compact, making it more convenient to carry when going out, and can meet the needs of rapid slope measurement. Attached Figure Description

[0025] Please see Figure 1-4 ,

[0026] Example 1: A slope measuring instrument for power civil engineering includes a support base 1, an installation frame 2 is provided at the top of the support base 1, a slope measuring component 3 is provided on the installation frame 2, a measuring drive component 4 is provided on the side of the installation frame 2, and a level 5 is provided on the side of the top of the installation frame 2.

[0027] The slope measurement component 3 includes a laser indicator 301 located in the middle of the mounting frame 2. Two side connecting blocks 302 are symmetrically arranged on both sides of the laser indicator 301. A fixed connecting plate 303 is fixed on the outer side of the mounting frame 2. An annular limiting groove 304 is opened on the inner wall of the fixed connecting plate 303. An angle plate 305 is arranged on the side of the fixed connecting plate 303. A transmission rod 306 is fixed on the side of the side connecting block 302. The end of the transmission rod 306 rotates through the side of the mounting frame 2. The end of the transmission rod 306 passes through the middle of the fixed connecting plate 303 and the angle plate 305 in sequence. A fixing ring 307 is fixed on the transmission rod 306. A pointer 308 is vertically arranged on the side of the fixing ring 307. The end of the pointer 308 extends into the annular limiting groove 304.

[0028] The measurement drive assembly 4 includes a drive chamber 401 fixed to the side of the mounting frame 2. A large gear 402 is rotatably disposed inside the drive chamber 401, and a small gear 403 is disposed on the side of the large gear 402. The central axis of the small gear 403 is rotatably connected to the inner wall of the drive chamber 401 and the outer wall of the mounting frame 2. The large gear 402 and the small gear 403 are meshed and connected. A rotating connecting rod 404 is fixed to the central shaft of the large gear 402. The end of the rotating connecting rod 404 rotatably passes through the mounting frame 2 and is fixedly connected to the side connecting block 302. A rotating handle 405 is disposed on the outer side of the drive chamber 401. The end of the rotating handle 405 rotatably passes through the drive chamber 401 and is fixedly connected to the central axis of the small gear 403.

[0029] Example 2: The difference between this example and Example 1 is that both the fixed connecting plate 303 and the angle plate 305 have through holes in their middle parts.

[0030] This makes it easier for the transmission rod 306 to pass through the middle of the fixed connecting plate 303 and the angle plate 305.

[0031] Example 3: The difference between this example and Example 1 is that the pointer 308 is located on the side of the angle disk 305, and the end of the pointer 308 extends into the annular limiting groove 304.

[0032] This allows the pointer 308 to better indicate the scale on the angle dial 305 under the drive of the transmission rod 306.

[0033] Example 4: The difference between this example and Example 1 is that the diameter of the large gear 402 is larger than the diameter of the small gear 403.

[0034] This makes the rotation of the small gear 403 and the large gear 402 slower.

[0035] In this embodiment, existing slope meters sometimes require workers to go up and down the foundation pit to take measurements, which is labor-intensive and cumbersome, and not conducive to the rapid measurement of slope.

[0036] In summary, in practical implementation, the laser pointer 301 used in this device is an existing product, such as the LMS30 series high-speed laser distance sensor, which has a built-in visible laser pointer, a power-saving mode, and is suitable for traffic control, industrial measurement, portable measurement systems, etc. This series includes two models: LMS30, which uses a narrow-beam laser for measurement and is designed for small targets, and LMSP30, which uses a wide-beam laser for measurement and can cover a wide area over a short distance. It is powered by a 5-14V power supply, with a power of 2.3W in full-speed mode and 0.1W in power-saving mode.

[0037] When a user needs to measure the angle of a slope in a power civil engineering project, the user can first place the support base 1 flat on the top of the slope, and adjust the overall level by using the level 5 set on the top of the mounting frame 2. When the laser indicator 301 in the slope measuring component 3 drives the pointer 308 to point to the top center of the angle disk 305, and the top center is 0°, the laser indicator 301 is also in a horizontal state.

[0038] Next, the user can rotate the rotating handle 405 in the measurement drive component 4. The rotating handle 405 drives the small gear 403 to rotate, and the small gear 403 meshes with the large gear 402, so that the small gear 403 drives the large gear 402 to rotate. The diameter of the large gear 402 is larger than the diameter of the small gear 403, so that the small gear 403 needs to rotate many times to drive the large gear 402 to rotate once. This achieves more precise control over the rotation angle of the large gear 402. The large gear 402 then drives the laser indicator 301 to rotate through the rotating connecting rod 404, making the angle adjustment of the laser indicator 301 more precise. When the laser emitted by the laser indicator 301 is in contact with or basically parallel to the surface of the slope.

[0039] At this time, the user can determine the slope angle by measuring the rotation angle of the pointer 308 driven by the laser indicator 301 on the surface of the angle disk 305 via the transmission rod 306. The device has a compact overall structure, is easy to operate, and is more convenient for users to carry and use when going out. Moreover, for the measurement of slope gradient, workers do not need to climb up and down the slope, making it more convenient to use and conducive to the rapid measurement of slope gradient.
