Description

Technical Field

[0001] This utility model relates to the field of surveying tools, specifically to a tool for measuring the slope height of water conservancy projects. Background Technology

[0002] When carrying out water conservancy projects, it is often necessary to measure the height of the slope. Existing technology, such as the Chinese utility model patent with authorization announcement number CN214039903U, discloses a device for quickly and synchronously measuring the angle and height of riverbank slopes. The angle measuring device can quickly measure the angle of the riverbank slope by reading the angle measuring device. Combined with a laser rangefinder or telescopic rangefinder to measure the distance from the bank shoulder to the slope toe, the height of the riverbank slope can be quickly and synchronously obtained.

[0003] However, the telescopic rangefinder has a very limited telescopic length and is only suitable for measuring slopes with small slopes. When the slope is long, the telescopic rangefinder is greatly limited by its length.

[0004] Therefore, the purpose of this utility model is to propose a tool for measuring the slope height of water conservancy projects to solve the above-mentioned problems. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] The telescopic distance measuring rod of existing slope height measuring devices has a very limited telescopic length, and is only suitable for measuring small slopes. When the slope length is large, the telescopic distance measuring rod will be greatly limited by its length.

[0007] 2. Technical Solution

[0008] To solve the above problems, this utility model provides the following technical solution: a tool for measuring the height of a slope in a water conservancy project, comprising a first rod for inserting into the top of the slope and a second rod for inserting into the bottom of the slope. A reel is rotatably mounted on the lower side of the second rod, and a belt ruler is wound around one end of the reel. An angle measuring mechanism is installed at the lower end of the second rod. The angle measuring mechanism includes a protractor fixedly connected to the second rod. A belt ruler guide tube is rotatably connected to the center of the protractor through a rotating shaft. The other end of the belt ruler connected to the reel passes through the interior of the belt ruler guide tube and is fixedly connected to the first rod.

[0009] 3. Beneficial effects

[0010] Compared with the prior art, the beneficial effects of this utility model are: by replacing the traditional telescopic measuring rod with a retractable belt ruler, the applicable slope length range is greatly expanded. Combined with the angle measuring mechanism, the slope angle can be obtained simultaneously. Combined with the calculator, the slope height can be quickly calculated. The overall structure is simple and easy to operate, effectively improving the applicability and efficiency of measuring the height of slopes of different lengths. Attached Figure Description

[0015] 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.

[0016] Please see Figure 1-4 This utility model discloses a tool for measuring the height of a slope in a water conservancy project. It includes a first rod 1 for inserting into the top of the slope and a second rod 4 for inserting into the bottom of the slope. Both the first rod 1 and the second rod 4 are made of stainless steel with a diameter of 20-30mm. The lower end is a conical tip for easy insertion into the soil on the slope. The rod is 80-100cm long. A winding wheel 5 is rotatably installed on the lower side of the second rod 4. One end of a belt ruler 2 is wound around the winding wheel 5. The other end of the belt ruler 2 is fixedly connected to the first rod 1.

[0017] When using it, first insert the first rod 1 at the top of the slope, and then extend the belt ruler 2 by using the reel 5 as you walk down the slope. When you reach the bottom of the slope, insert the second rod 4 at the bottom of the slope. At this time, the length L of the slope can be obtained by the length of the belt ruler 2. Compared with the existing telescopic distance measuring rod for measuring slope length, the belt ruler 2 is longer and can adapt to the surveying work of long slopes.

[0018] To facilitate the measurement of the slope angle α, an angle measuring mechanism 6 is installed at the lower end of the second insert 4. The angle measuring mechanism 6 includes a protractor 62 fixedly connected to the second insert 4. A belt ruler guide tube 61 is rotatably connected to the center of the protractor 62 via a rotating shaft 63. Specifically, one end of the rotating shaft 63 is fixedly connected to the side of the belt ruler guide tube 61, and the other end of the rotating shaft 63 is fixedly connected to the center of the protractor 62. The other end of the belt ruler 2, connected to the reel 5, passes through the interior of the belt ruler guide tube 61 and is fixedly connected to the first insert 1. Figure 2 and Figure 3 As shown, the angle of the guide tube 61 of the belt tape measure is automatically adjusted according to the tension of the belt tape 2, ensuring that the axis of the guide tube 61 of the belt tape measure is completely consistent with the direction of the belt tape 2, and then the accurate slope angle α is obtained by pointing the end of the guide tube 61 of the belt tape measure to the scale of the protractor 62.

[0019] The height h of the slope is equal to the length L of the slope, sin α. The upper end of the second rod 4 is fixed with a calculator 3 by bolts, clips, etc., which makes it convenient to calculate the height h of the slope. The calculator 3 can be a common small portable handheld calculator on the market, such as the Casio SL-300VC or Deli 1541A.

[0020] The lower end of the second insert rod 4 is provided with a wire groove 41. The reel 5 is installed on the side of the wire groove 41 away from the first insert rod 1. The protractor 62 is fixed on the side of the wire groove 41 close to the first insert rod 1. The other end of the belt ruler 2 connected to the reel 5 passes through the inside of the wire groove 41 and is connected to the belt ruler guide tube 61 of the protractor 62.

[0021] A pulley 42 is installed inside the wire groove 41, and the belt ruler 2 slides in contact with the pulley 42.

[0022] The rotating shaft of the reel 5 is fixed with a handle 51. The handle 51 facilitates the winding and unwinding of the belt ruler 2. The belt ruler 2 can be made of fabric. The reel 5 is installed on the second insert rod 4 via a mounting bracket 52. Specifically, the mounting bracket 52 is fixed to the second insert rod 4, and the reel 5 is rotatably mounted on the mounting bracket 52. There is a certain friction between the side of the reel 5 and the mounting bracket 52. This friction ensures that the reel 5 does not rotate when the handle 51 is not operated.

[0023] This utility model aims to provide a tool for measuring the height of slopes in water conservancy projects, in order to solve the problem that the telescopic measuring rod in existing slope height measuring devices has a limited length and is only suitable for measuring small slopes. By setting up a retractable belt ruler 2 to adapt to the measurement of the slope length of longer slopes, and by combining it with an angle measuring mechanism 6 consisting of a protractor 62 and a belt ruler guide tube 61 to obtain the slope angle, and combining it with a calculator 3 to assist in calculating the slope height (slope height h = slope length L × sin slope angle α), a convenient and accurate measurement of the height of slopes of different lengths can be achieved.

[0024] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0025] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
