Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering technology, specifically relating to a canal slope measuring device used in water conservancy projects. Background Technology

[0002] A canal is a man-made waterway, which can be divided into main canals and branch canals. Main canals and branch canals are generally constructed of stone or cement.

[0003] During the construction of irrigation canals, it is necessary to measure the slope of the canals. Currently, angle rulers are generally used to measure the slope of irrigation canals. Since the inclined surface of the irrigation canal is long, additional tools such as straight boards are needed for auxiliary measurement. The measurement process is cumbersome and prone to errors. Based on this, this utility model provides an irrigation canal slope measuring device for use in water conservancy projects. Utility Model Content

[0008] As a preferred technical solution of the canal slope measuring device used in water conservancy projects according to this utility model, the distance between the first limiting plate and the second limiting plate is adapted to the bottom thickness of the inverted L-shaped pointing plate. A first through hole is opened at the bottom of the front of the inverted L-shaped pointing plate, and a second through hole is opened in the middle of the front of the inverted L-shaped pointing plate.

[0009] As a preferred technical solution of the canal slope measuring device used in water conservancy engineering according to this utility model, the inner diameters of the first and second locking holes, the first through hole, and the second through hole are all the same. A first connecting bolt is installed through the first locking hole and the first through hole, and a second connecting bolt is installed through the second locking hole and the second through hole.

[0010] As a preferred technical solution for a canal slope measuring device used in water conservancy projects according to this utility model, the distance between the No. 1 through hole and the indicator arrow block is greater than the radius of the semi-circular angle plate.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0021] Please see Figures 1-5 This utility model provides the following technical solution: A canal slope measuring device used in water conservancy projects, comprising a base plate 1, a first limiting plate 2 welded to one side of the top center of the base plate 1, and a second limiting plate 3 welded to the other side of the top center of the base plate 1. The thickness of the first limiting plate 2 and the second limiting plate 3 are the same. A semi-annular angle plate 4 is welded to one side of the top of the first limiting plate 2 and the top of the second limiting plate 3. The diameter of the semi-annular angle plate 4 is the same as the length of the second limiting plate 3. The thickness of the annular angle plate 4 is the same as the thickness of the second limiting plate 3. A first locking hole 5 is provided on one side of the front of the first limiting plate 2 and in the middle of the front of the corresponding second limiting plate 3. A second locking hole 6 is provided on one side of the front of the first limiting plate 2 and on one side of the front of the corresponding second limiting plate 3. An inverted L-shaped guide plate 7 is movably installed between the first limiting plate 2 and the second limiting plate 3. The distance between the first limiting plate 2 and the second limiting plate 3 is appropriate to the bottom thickness of the inverted L-shaped guide plate 7. The fitting allows for positioning and limiting of the inverted L-shaped guide plate 7. A first through hole 8 is formed at the bottom of the front of the inverted L-shaped guide plate 7, and a second through hole 9 is formed in the middle of the front of the inverted L-shaped guide plate 7. The inner diameters of the first locking hole 5, the second locking hole 6, the first through hole 8, and the second through hole 9 are all the same. A first connecting bolt 10 is installed through the first locking hole 5 and the first through hole 8 to facilitate the movable installation of the inverted L-shaped guide plate 7. Both ends of the inverted L-shaped guide plate 7 are equipped with indicator arrow blocks 11. The distance between the first through hole 8 and the indicator arrow block 11 is greater than the radius of the semi-annular angle plate 4, which facilitates the rotation of the inverted L-shaped guide plate 7. The second locking hole 6 and the second through hole 9 are fitted with second connecting bolts 14, which can fix the inverted L-shaped guide plate 7 and facilitate its folding and storage. The top side of the inverted L-shaped guide plate 7 is provided with a mounting hole 12, and a level tube 13 is installed inside the mounting hole 12. The level tube 13 is an existing technology device, and its specific structure will not be described in detail here.

[0022] The working principle and usage process of this utility model are as follows: During the use of this utility model, the operator removes the No. 2 connecting bolt 14 that fixes the inverted L-shaped guide plate 7. Then, the operator places the device on the inclined surface of the water channel (water channel slope). After the base plate 1 is in close contact with the inclined surface of the water channel, the operator rotates the inverted L-shaped guide plate 7 to adjust its angle. By observing the position of the bubble inside the level tube 13, the verticality of the inverted L-shaped guide plate 7 can be visually checked. When the inverted L-shaped guide plate 7 is perpendicular to the ground, the operator checks the pointing angle between the indicator arrow block 11 and the semi-circular angle plate 4. At this time, the angle pointed by the indicator arrow block 11 on the semi-circular angle plate 4 is the slope of the inclined surface of the water channel, which facilitates the use of the device.

[0023] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
