Abstract
Description
Technical Field
[0001] This utility model belongs to the field of measuring device technology, specifically relating to a water channel slope measuring device. Background Technology
[0002] Currently, existing canal slope measurement equipment typically operates as follows: a rotating frame is positioned against a suitable location on the canal slope, and then an angle gauge is used to determine the slope angle based on the corresponding point on the rotating frame. This measurement method can meet basic measurement needs to a certain extent, providing necessary data support for the construction and maintenance of water conservancy projects.
[0003] However, in actual operation, this measuring device has obvious drawbacks. When workers record the slope, the rotating frame needs to be locked to ensure stable observation and recording, preventing its swaying from affecting judgment and observation. However, locking the rotating frame undoubtedly increases the workload of workers, especially when a large number of measurements are required, significantly reducing measurement efficiency. Conversely, if it is not locked, the rotating frame is easily affected by external factors (such as slight touches from workers, wind, etc.), leading to inaccurate observation data, which in turn affects the design and construction quality of subsequent water conservancy projects. Utility Model Content
[0004] This invention provides a canal slope measuring device, which reduces the workload of slope measurement while ensuring accurate slope readings.
[0005] This utility model provides the following technical solution: It includes a mounting base, with an arc-shaped ruler plate mounted on its top. An angle positioning plate is slidably connected to the arc-shaped side of the ruler plate. Scale lines are provided on both sides of the arc-shaped ruler plate, with each scale line corresponding to a position on one side of the angle positioning plate. Two damping pads are mounted on the inner side of the angle positioning plate, slidably connected to corresponding sides of the arc-shaped ruler plate. Two fixed seats are mounted on the top of the mounting base, with a rotating frame rotatably connected between them. A U-shaped rotating frame is mounted at the bottom of the rotating frame, contacting one side of the angle positioning plate but not contacting the arc-shaped ruler plate.
[0006] The mounting base has four fixed cones installed at its bottom, and all four fixed cones are located at the bottom corner of the mounting base.
[0007] The arc-shaped ruler plate is provided with a sliding track groove, and the inner wall of the angle positioning plate is equipped with a T-shaped limiting slider, which is slidably connected to the inner wall of the sliding track groove.
[0008] The angle positioning plate has strip-shaped observation holes on both sides, and the positions of the strip-shaped observation holes correspond to the scale lines.
[0009] The top of the U-shaped rotating frame is provided with a clearance slot, and the angle positioning plate is engaged with the inner wall of the clearance slot.
[0010] The mounting base is rotatably connected to an L-shaped limiting plate at its top, and an anti-slip pad is fixedly connected to the bottom of the L-shaped limiting plate. The anti-slip pad is slidably connected to the inner wall of the clearance slot.
[0011] The rotating frame has a telescopic frame slidably connected to its inner wall, and neither the rotating frame nor the telescopic frame is in contact with the arc-shaped ruler plate.
[0012] The beneficial effects of this utility model are as follows: After the U-shaped rotating frame pushes and retracts the angle positioning plate, the angle positioning plate is kept in the corresponding position by the damping pad. The fixed position of the angle positioning plate is no longer affected by the U-shaped rotating frame, which allows the staff to record data stably, ensure the accuracy of the observation data, and prevent it from affecting the design and construction quality of subsequent water conservancy projects. There is no need to perform unnecessary locking work on the rotating frame or U-shaped rotating frame, which reduces the workload of the staff, especially when a large number of measurements are required, thus improving the measurement efficiency.

Detailed Implementation
[0019] Please see Figures 1-4 The present invention provides the following technical solution: it includes a mounting base 1, an arc-shaped ruler plate 2 mounted on the top of the mounting base 1, an angle positioning plate 3 slidably connected to the arc-shaped side of the arc-shaped ruler plate 2, scale lines 21 set on both sides of the arc-shaped ruler plate 2, the two scale lines 21 corresponding to the positions of the two sides of the angle positioning plate 3 respectively, two damping pads 31 mounted on the inner side of the angle positioning plate 3, the two damping pads 31 slidably connected to the corresponding side of the arc-shaped ruler plate 2 respectively, two fixed seats 11 mounted on the top of the mounting base 1, a rotating frame 4 rotatably connected between the two fixed seats 11, a U-shaped rotating frame 41 mounted on the bottom of the rotating frame 4, the U-shaped rotating frame 41 contacting one side of the angle positioning plate 3, and not contacting the arc-shaped ruler plate 2.
[0020] In this implementation scheme: the mounting base 1 provides bottom support for each component of the device. The mounting base 1 supports the rotating frame 4 through two fixed seats 11. The rotating frame 4 rotates around the connection points of the two fixed seats 11. When in use, the rotating frame 4 rests against the slope. The angle formed between the U-shaped rotating frame 41 and the mounting base 1 reflects the angle of the slope. The rotating frame 4 supports and drives the U-shaped rotating frame 41 to rotate. The angle between the U-shaped rotating frame 41 and the rotating frame 4 is a fixed ninety-degree angle. The arc-shaped ruler 2 is a quarter angle. The scale line 21 on the arc-shaped ruler 2 also reads 90 degrees. When the rotating frame 4 drives the U-shaped rotating frame 41 to rotate, the U-shaped rotating frame 41 rotates synchronously on the arc-shaped ruler 2. The point between the U-shaped rotating frame 41 and the scale line 21 can measure the angle of rotation of the U-shaped rotating frame 41, thus reflecting the angle of the canal slope. The angle positioning plate 3 slides along the circular path on the arc-shaped ruler 2. When the U-shaped rotating frame 41 rotates upward, it can push the angle positioning plate 3 to rotate, so that the angle positioning plate 3 can follow the U-shaped rotating frame 2. The U-shaped rotating frame 41 rotates synchronously. The angle positioning plate 3 itself has a U-shaped design, which allows the two legs of the angle positioning plate 3 to be aligned with the scale lines 21 on both sides of the arc-shaped ruler 2 for measurement. Two damping pads 31 increase the friction between the angle positioning plate 3 and the arc-shaped ruler 2, so that the angle positioning plate 3 can maintain a stable position without being pushed by the rotating frame 4 or personnel. After the rotating frame 4 and the U-shaped rotating frame 41 are used, the angle positioning plate 3 is pushed to its current position by the U-shaped rotating frame 41 and will not move. The rotating frame 4 can rotate back towards the arc-shaped ruler 2. Then, the staff can directly take the reading. The angle positioning plate 3 remains in a fixed position and will not be changed by the U-shaped rotating frame 41, so that the staff can record data stably, ensure the accuracy of the observation data, and prevent it from affecting the design and construction quality of subsequent water conservancy projects. There is no need to do unnecessary locking work on the rotating frame 4 or the U-shaped rotating frame 41, which reduces the workload of the staff, especially when a large number of measurements are required, thus improving the measurement efficiency.
[0021] Four fixed cones 12 are installed at the bottom of the mounting base 1. All four fixed cones 12 are located at the bottom corner of the mounting base 1. The mounting base 1 is fixed to the observation position by the four fixed cones 12, so that the mounting base 1 maintains a stable position and does not shake, thus ensuring the accuracy of the measurement.
[0022] The curved ruler plate 2 has a sliding track groove 22, and the inner wall of the angle positioning plate 3 is equipped with a T-shaped limiting slider 32, which is slidably connected to the inner wall of the sliding track groove 22. The curved ruler plate 2 provides sliding guidance and limitation for the T-shaped limiting slider 32 through the sliding track groove 22, so that the T-shaped limiting slider 32 can drive the angle positioning plate 3 to slide on the set route, preventing the angle positioning plate 3 from moving off course or tilting at an angle, and further ensuring the accuracy of the degree reading.
[0023] The angle positioning plate 3 has strip-shaped observation holes 33 on both sides, and the strip-shaped observation holes 33 correspond to the scale line 21. The two strip-shaped observation holes 33 are distributed on the legs on both sides of the angle positioning plate 3. After the angle positioning plate 3 slides to a certain position, the two strip-shaped observation holes 33 can encircle the scale line 21 at the position, which makes it easier for the staff to accurately measure the degree, reduce the interference from the scale line 21 next to it, and make it easier to judge.
[0024] The top of the U-shaped rotating frame 41 has a clearance slot 411, and the angle positioning plate 3 is engaged with the inner wall of the clearance slot 411. The U-shaped rotating frame 41 makes way for the angle positioning plate 3 through the clearance slot 411, so that the U-shaped rotating frame 41 can be stably connected with the angle positioning plate 3. The clearance slot 411 also makes the center position of the angle positioning plate 3 correspond to that of the U-shaped rotating frame 41, preventing the thickness of the U-shaped rotating frame 41 from interfering with the driving displacement of the angle positioning plate 3, and further improving the accuracy of the measurement data.
[0025] An L-shaped limiting plate 13 is rotatably connected to the top of the mounting base 1, and an anti-slip pad 131 is fixedly connected to the bottom of the L-shaped limiting plate 13. The anti-slip pad 131 is slidably connected to the inner wall of the clearance slot 411. When the L-shaped limiting plate 13 rotates away from the arc-shaped ruler plate 2, the U-shaped rotating frame 41 is unlocked and can rotate with the U-shaped rotating frame 41. When the L-shaped limiting plate 13 drives the anti-slip pad 131 to rotate above the surface of the clearance slot 411, the L-shaped limiting plate 13 limits the U-shaped rotating frame 41, so that the rotating frame 4 and the U-shaped rotating frame 41 remain stable with respect to the mounting base 1, preventing shaking and facilitating transfer and storage. The anti-slip pad 131 increases the stability of the L-shaped limiting plate 13 in limiting the U-shaped rotating frame 41.
[0026] The inner wall of the rotating frame 4 is slidably connected to the telescopic frame 42. Neither the rotating frame 4 nor the telescopic frame 42 is in contact with the arc-shaped ruler plate 2. The telescopic frame 42 and the rotating frame 4 can be adjusted to combine in length, so that when measuring slopes of different sizes, the corresponding length can be adjusted to improve the accuracy of the measurement.
[0027] The working principle and usage process of this utility model are as follows: During measurement, the mounting base 1 is installed at the measuring station. Then, the L-shaped limiting plate 13 is rotated to unlock the U-shaped rotating frame 41. The rotating frame 4 drives the U-shaped rotating frame 41 to rotate. The rotating frame 4 rests against the slope surface. The angle formed between the U-shaped rotating frame 41 and the mounting base 1 reflects the angle of the slope surface. After the U-shaped rotating frame 41 rotates synchronously on the arc-shaped ruler 2, the point between the U-shaped rotating frame 41 and the scale line 21 can measure the angle of rotation of the U-shaped rotating frame 41, thus reflecting... The angle of the canal slope is determined by the angle positioning plate 3 sliding along a circular path on the arc-shaped ruler plate 2. When the U-shaped rotating frame 41 rotates upward, it can push the angle positioning plate 3 to rotate, so that the angle positioning plate 3 can rotate synchronously with the U-shaped rotating frame 41. The angle positioning plate 3 and the arc-shaped ruler plate 2 are connected by two damping pads 31 to increase the friction, so that the angle positioning plate 3 can maintain a stable position without being pushed by the rotating frame 4 or personnel. The rotating frame 4 and the U-shaped rotating frame 41 can be retracted, and the staff can observe and measure the angle through the strip observation hole 33.
