Technical Field
[0001] This utility model relates to the field of river measurement technology, specifically a water conservancy river measurement tool. Background Technology
[0002] Water conservancy and river channel monitoring is a comprehensive engineering activity that uses systematic technical means to collect, analyze, and evaluate data on rivers and related water conservancy facilities. Its core objective is to ensure the stability of river functions, flood control safety, and ecological sustainability.
[0003] In the prior art, the width of a river channel is generally measured using a laser rangefinder. However, laser rangefinders are subject to severe scattering in foggy or dusty weather, and the measurement error may exceed ±5%, thus affecting the accuracy of the measurement. Based on the shortcomings of the existing technology, this utility model designs a water conservancy river channel measurement tool. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a water conservancy river channel measurement tool, which has the advantages of measuring river channel width through a mechanical structure and can still be measured in smoggy weather.
[0005] This utility model provides the following technical solution: a water conservancy river channel surveying tool, including an unmanned surface vessel (USV). An installation frame is fixedly installed on the top of the USV's outer surface. Installation grooves are formed on both sides of the outer surface of the installation frame. A wire-laying structure is fixedly installed inside the two installation grooves. The wire-laying structure includes an installation plate. Side plates are fixedly installed on both sides of the bottom of the installation plate. A wire spool is rotatably installed between the two side plates. A U-shaped frame is fixedly installed at the end of the wire spool. A rotating rod is fixedly installed inside the U-shaped frame. A connecting seat is rotatably installed on the outer surface of the rotating rod. A pin is movably installed inside the connecting seat. A limit plate is fixedly installed on the top of the pin.
[0006] By adopting the above technical solution and using a line-laying structure, when measuring the width of a river channel in foggy weather, the unmanned boat is anchored to the edge of the riverbank with pins. Then, the unmanned boat is placed in the water and remotely controlled to cross the river. When the unmanned boat reaches the other side of the river, the line reel is fixed by a fixing structure, preventing further line release. Since the line reel is colored every ten meters, the length of the river channel can be determined by straightening the reel and observing the color of the released line. The accuracy error is small, thus achieving the goal of measurement even in foggy weather.
[0007] As a preferred embodiment of this utility model, a lifting rod is fixedly installed on the top of the mounting plate.
[0008] By adopting the above technical solution and by setting up the lifting rod, the mounting plate can be easily lifted out of the mounting slot when changing lines.
[0009] As a preferred embodiment of this utility model, two fixing nuts are threadedly installed on both sides of the top of the mounting plate, and the two sets of fixing nuts are threadedly connected to the mounting frame.
[0010] By adopting the above technical solution and using two fixing nuts, the mounting plate can be fixedly connected to the mounting frame.
[0011] As a preferred embodiment of this utility model, the winding roller of the wire coil is fixedly installed with rotating covers at both ends, and the two rotating covers have internal grooves.
[0012] By adopting the above technical solution, the rotating cover can be rotatably connected to the mounting frame, and the inner groove facilitates subsequent positioning of the wire coil.
[0013] As a preferred embodiment of this utility model, a fixed structure is fixedly installed on both sides of the outer surface of the unmanned vessel, and a receiving antenna is fixedly installed on both sides of the top of the unmanned vessel.
[0014] By adopting the above technical solution, control signals are received.
[0015] As a preferred embodiment of this utility model, the two fixing structures include two fixing plates, which are threadedly connected to the unmanned vessel.
[0016] By adopting the above technical solution, the rotating cover and inner tank can be waterproofed by using a fixing plate.
[0017] As a preferred embodiment of this utility model, a side cover is fixedly installed between the two fixed plates, and a hexagonal rod is movably installed inside the two side covers.
[0018] By adopting the above technical solution, the inner groove angle is made to match the hexagonal rod by tightening part of the wire coil, and the hexagonal rod is moved inside the side cover by pressing the push plate.
[0019] As a preferred embodiment of this utility model, the dimensions of the two hexagonal rods match the inner groove, and a pressing plate is fixedly installed at the other end of the two hexagonal rods.
[0020] By adopting the above technical solution, the hexagonal rod is inserted into the inner groove and fixed, at which point the wire reel no longer unwinds, allowing the length of the river channel to be checked. Compared with the prior art, this utility model has the following beneficial effects:
[0021] 1. This water conservancy river channel measurement tool, through a line-laying structure, allows for the measurement of river channel width in foggy or hazy weather. It involves anchoring pins to the riverbank edge, then placing an unmanned boat in the water and remotely controlling it to cross the river. Once the boat reaches the other side, a fixed structure secures the line reel, preventing further line release. The line reel is color-coded every ten meters, so the river length can be determined by straightening the reel and observing the color of the released line. This method offers minimal accuracy and achieves the goal of measurement even in foggy or hazy weather.
[0022] 2. This water conservancy river channel measurement tool, through a fixed structure, ensures that when an unmanned vessel travels through the river channel, the hexagonal rod does not contact the rotating cover, allowing the wire reel to rotate and release the wire. When the unmanned vessel reaches the other side of the river channel, the angle of the inner groove can be aligned with the hexagonal rod by tightening part of the wire reel, and the hexagonal rod can be moved inside the side cover by pressing the actuating plate, thereby inserting the hexagonal rod into the inner groove and fixing it. At this time, the wire reel no longer releases wire, and the length of the river channel can be viewed. Attached Figure Description

[0029] 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.
[0030] Please see Figure 1-5 A water conservancy river channel surveying tool includes an unmanned vessel 1. An installation frame 2 is fixedly installed on the top of the outer surface of the unmanned vessel 1. Installation grooves 21 are opened on both sides of the outer surface of the installation frame 2. A wire laying structure 3 is fixedly installed inside the two installation grooves 21. The wire laying structure 3 includes an installation plate 31. Side plates 34 are fixedly installed on both sides of the bottom of the installation plate 31. A wire reel 35 is rotatably installed between the two side plates 34. A U-shaped frame 38 is fixedly installed at the wire end of the wire reel 35. A rotating rod 39 is fixedly installed inside the U-shaped frame 38. A connecting seat 310 is rotatably installed on the outer surface of the rotating rod 39. A pin 311 is movably installed inside the connecting seat 310. A limit plate 312 is fixedly installed on the top of the pin 311.
[0031] Please see Figure 2-3 A lifting rod 32 is fixedly installed on the top of the mounting plate 31. Two fixing nuts 33 are threadedly installed on both sides of the top of the mounting plate 31, and the two sets of fixing nuts 33 are threadedly connected to the mounting frame 2. Turning covers 36 are fixedly installed at both ends of the winding roller of the wire coil 35, and the interior of the two turning covers 36 is provided with an inner groove 37.
[0032] By fixing the nut 33 to the mounting frame 2 with a threaded connection, the wire feeding structure 3 can be removed from the mounting frame 2 as a whole, and wire reels 35 of different lengths can be replaced.
[0033] Please see Figure 1-5 The unmanned surface vessel 1 has two fixed structures 4 fixedly installed on its outer surface, and two receiving antennas 5 fixedly installed on its top. Each fixed structure 4 includes two fixed plates 41, which are threadedly connected to the unmanned surface vessel 1. Side covers 42 are fixedly installed between the two fixed plates 41, and hexagonal rods 43 are movably installed inside the two side covers 42. The dimensions of the two hexagonal rods 43 match the inner groove 37, and a push plate 44 is fixedly installed at the other end of each hexagonal rod 43.
[0034] When the unmanned vessel 1 is traveling in the river, the hexagonal rod 43 is not in contact with the rotating cover 36. At this time, the wire reel 35 can be rotated to release the wire. When the unmanned vessel 1 reaches the other side of the river, the angle of the inner groove 37 can be made to match the hexagonal rod 43 by tightening part of the wire reel 35, and the pressing plate 44 can be pressed to move the hexagonal rod 43 inside the side cover 42, so that the hexagonal rod 43 is inserted into the inner groove 37 and fixed. At this time, the wire reel 35 no longer releases wire, and the length of the river can be checked.
[0035] Working principle: When a water conservancy river channel measuring tool is used, it is first anchored to the edge of the riverbank by pin 311. Then, the unmanned boat 1 is placed in the water and remotely controlled to cross the river channel. When the unmanned boat 1 is crossing the river channel, the hexagonal rod 43 does not contact the rotating cover 36. At this time, the wire reel 35 can be rotated to release the wire. When the unmanned boat 1 reaches the other side of the river channel, the angle of the inner groove 37 can be matched with the hexagonal rod 43 by tightening part of the wire reel 35, and the pressing plate 44 can be pressed to move the hexagonal rod 43 inside the side cover 42, so that the hexagonal rod 43 is inserted into the inner groove 37 and fixed. At this time, the wire reel 35 no longer releases wire. Since the wire reel 35 is colored every ten meters in sequence, the length of the river channel can be determined by straightening the wire reel 35 and checking the color released, and the accuracy error is small.
[0036] 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.
