Description

Technical Field

[0001] This utility model relates to the field of depth sounding instruments for water conservancy construction, and in particular to a portable depth sounding instrument suitable for water conservancy construction. Background Technology

[0002] In water conservancy construction, depth sounders are a very important tool. Ultrasonic depth sounders are usually used to measure the depth of water bodies, thereby helping construction personnel to carry out underwater topographic surveying, water resource management, and construction design.

[0003] According to the Chinese patent "An Ultrasonic Depth Sounder for Portable Topographic Surveying of Water Conservancy Projects" (authorization announcement number "CN217867884U"), two cleaning rollers are used to wipe the dirt on the suspension rope to keep it clean and prevent dirt or debris from being rolled into the control box. With the help of the pin and torsion spring, the cleaning rollers make elastic contact with the suspension rope, resulting in better cleaning effect.

[0004] The limited contact area between the cleaning roller and the hoisting rope in the aforementioned application makes it difficult for the cleaning roller to thoroughly clean the hoisting rope, thus affecting the cleaning effect on the hoisting rope.

[0005] Therefore, a portable depth sounder suitable for water conservancy construction is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a portable depth sounder suitable for water conservancy construction in order to solve the above-mentioned problems, thereby improving the problem that the limited contact area between the cleaning roller and the hoisting rope makes it difficult for the cleaning roller to clean the hoisting rope completely.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a portable depth sounder suitable for water conservancy construction, comprising: a transparent frame, wherein a driving mechanism is provided inside the transparent frame; a cleaning mechanism, wherein the cleaning mechanism includes a first bevel gear rotatably connected to the lower end of the inner wall of the transparent frame, a connecting ring fixedly connected to the bottom end of the first bevel gear, two arc-shaped brushes slidably connected to the inner wall of the connecting ring, a spring fixedly connected to the opposite end of the arc-shaped brush and the connecting ring, a second bevel gear meshing with the top end of the first bevel gear, and two smooth rods provided on the inner surface of the arc-shaped brush.

[0008] Preferably, the driving mechanism includes a take-up roller rotatably connected to the inner wall of the transparent frame. A suspension rope is wound around the surface of the take-up roller, and a mounting ring is fixedly connected to the bottom end of the suspension rope. An ultrasonic depth sounder is installed on the inner wall of the mounting ring. Through a first bevel gear, a second bevel gear, and a connecting ring, two arc-shaped brushes rotate and thoroughly clean the longitudinally moving suspension rope. A spring ensures that the bristles on the arc-shaped brushes remain in contact with the surface of the suspension rope, guaranteeing effective cleaning. A smooth rod agitates the bristles of the rotating arc-shaped brushes, shaking off impurities attached to the bristles and preventing them from adhering to the bristles.

[0009] Preferably, a first gear is fixedly connected to the surface of the take-up roller, a second gear is meshed with the lower end of the surface of the first gear, one end of the second bevel gear is fixedly connected to one end of the second gear, a servo motor is fixedly connected to one end of the second gear, and the surface of the servo motor is fixedly connected to the lower end of the inner wall of the transparent frame.

[0010] Preferably, a limiting frame is fixedly connected to both the upper and lower ends of the smooth rod surface, and annularly distributed ball bearings are rolled on the inner surface of the limiting frame. The limiting frame and the ball bearings limit the longitudinal movement of the suspension rope, ensuring that the bristles on the arc-shaped brush adhere to the suspension rope.

[0011] Preferably, a bracket is fixedly connected to the surface of one of the limiting frames, and the top of the bracket is fixedly connected to the bottom of the transparent frame.

[0012] Preferably, a soft sleeve is fixedly connected to the opposite end of the arc-shaped brush and the connecting ring. The soft sleeve protects the spring and prevents impurities from adhering to the spring surface.

[0013] Preferably, a baffle is fixedly connected to the inner bottom wall of the transparent frame, and the surface of the second bevel gear is rotatably connected to the inner wall of the baffle. The baffle effectively encloses the first and second bevel gears, preventing the hanging rope on the take-up roller from falling onto the second bevel gear.

[0014] The beneficial effects of this utility model are:

[0015] By using the first bevel gear, the second bevel gear, and the connecting ring, two arc-shaped brushes are rotated to thoroughly clean the longitudinally moving suspension rope. A spring ensures that the bristles on the arc-shaped brushes remain in contact with the surface of the suspension rope. Compared to existing methods that cannot thoroughly clean the suspension rope, this method uses the rotation of two arc-shaped brushes to thoroughly clean the suspension rope, ensuring a good cleaning effect. A smooth rod is used to move the bristles on the rotating arc-shaped brushes, thereby shaking off impurities attached to the bristles and preventing impurities from adhering to the bristles of the arc-shaped brushes.

[0016] By using a limiting frame and ball bearings, the longitudinal movement of the suspension rope is limited, ensuring that the bristles on the curved brush can adhere to the suspension rope. Attached Figure Description

[0022] 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.

[0023] In practical implementation: such as Figure 1-4 As shown, a portable depth sounder suitable for water conservancy construction includes: a transparent frame 1, with a drive mechanism 2 inside the transparent frame 1; a cleaning mechanism 3, which includes a first bevel gear 31 rotatably connected to the lower end of the inner wall of the transparent frame 1, a connecting ring 32 fixedly connected to the bottom end of the first bevel gear 31, two arc-shaped brushes 33 slidably connected to the inner wall of the connecting ring 32, a spring 34 fixedly connected to the opposite end of the arc-shaped brushes 33 and the connecting ring 32, a second bevel gear 35 meshing with the top end of the first bevel gear 31, and two smooth rods 38 on the inner surface of the arc-shaped brushes 33. The bristles on the surface of the arc-shaped brushes 33 are made of nylon, and the smooth rods 38 are made of stainless steel.

[0024] like Figure 2As shown, the drive mechanism 2 includes a take-up roller 21 rotatably connected to the inner wall of the transparent frame 1. A suspension rope 22 is wound around the surface of the take-up roller 21. A mounting ring 23 is fixedly connected to the bottom end of the suspension rope 22. An ultrasonic depth sounder 24 is provided on the inner wall of the mounting ring 23. A first gear 25 is fixedly connected to the surface of the take-up roller 21. A second gear 26 is meshed with the lower end of the surface of the first gear 25. One end of the second bevel gear 35 is fixedly connected to one end of the second gear 26. A servo motor 27 is fixedly connected to one end of the second gear 26. The surface of the servo motor 27 is fixedly connected to the lower end of the inner wall of the transparent frame 1.

[0025] The ultrasonic depth sounder 24 is mounted on the inner wall of the mounting ring 23 by bolts. The ultrasonic depth sounder 24 adopts a wireless connection. The diameter of the first gear 25 is larger than the diameter of the second gear 26. The specific gear diameter ratio is selected according to actual needs.

[0026] When it is necessary to detect the water level depth at the water conservancy construction site, in the initial state, the ultrasonic depth sounder 24 is brought close to the bottom of the connecting ring 32 by winding up the suspension rope 22, which facilitates carrying the depth sounder. The transparent frame 1 is installed at the location to be detected by bolts. The servo motor 27 is manually turned on. The output shaft of the servo motor 27 rotates, which drives the second gear 26 to rotate. The rotation of the second gear 26 drives the first gear 25 to rotate slowly. The rotation of the first gear 25 drives the winding roller 21 to rotate. The rotation of the winding roller 21 loosens the suspension rope 22, causing the suspension rope 22 to move vertically downward and drive the mounting ring 23 and the ultrasonic depth sounder 24 to move down to a suitable height. Then, the servo motor 27 is manually turned off and the ultrasonic depth sounder 24 is turned on. The ultrasonic depth sounder 24 emits sound waves underwater. The sound waves propagate in the water and reflect back when they hit the bottom. After receiving the echo, the ultrasonic depth sounder 24 determines the water depth by calculating the propagation time and speed of the sound waves. The detected water level depth is transmitted to the display screen controller connected to the ultrasonic depth sounder 24 for the testing personnel to view the water level depth data.

[0027] After the test is completed, manually turn off the ultrasonic depth sounder 24 and turn on the servo motor 27. The output shaft of the servo motor 27 rotates, which, through the second gear 26, the first gear 25, and the winding roller 21, winds up the suspension rope 22, causing the suspension rope 22 to move longitudinally upward. The rotation of the second gear 26 drives the second bevel gear 35 to rotate, which in turn drives the first bevel gear 31 and the connecting ring 32 to rotate. The rotation of the connecting ring 32 drives the two arc-shaped brushes 33 to rotate, which clean the longitudinally moving suspension rope 22, causing impurities to fall off the surface of the suspension rope 22. The bristles on the rotating arc-shaped brushes 33 touch the smooth rod 38, causing the bristles to deform and thus removing the impurities attached to the bristles. After the suspension rope 22, the mounting ring 23, and the ultrasonic depth sounder 24 have moved to a suitable height, manually turn off the servo motor 27.

[0028] like Figure 3 As shown, the upper and lower ends of the surface of the smooth rod 38 are fixedly connected to the limiting frame 36. The inner surface of the limiting frame 36 is rolled with annularly distributed balls 37. One of the limiting frames 36 is fixedly connected to the surface of the limiting frame 36, and the top of the bracket 310 is fixedly connected to the bottom of the transparent frame 1.

[0029] like Figure 3-4 As shown, a soft sleeve 39 is fixedly connected to the opposite end of the arc-shaped brush 33 and the connecting ring 32, and a baffle 311 is fixedly connected to the inner bottom wall of the transparent frame 1. The surface of the second bevel gear 35 is rotatably connected to the inner wall of the baffle 311. The soft sleeve 39 is a rubber component.

[0030] In use, the output shaft of the servo motor 27 rotates and, through the second gear 26, the first gear 25 and the winding roller 21, winds up the suspension rope 22, causing the suspension rope 22 to move longitudinally upward inside the limiting frame 36. The elastic force of the spring 34 pushes the arc-shaped brush 33 toward the suspension rope 22, so that the bristles on the arc-shaped brush 33 come into contact with the suspension rope 22. The rotation of the second gear 26 drives the two arc-shaped brushes 33 to rotate through the second bevel gear 35, the first bevel gear 31 and the connecting ring 32. The rotation of the two arc-shaped brushes 33 cleans the longitudinally upward-moving suspension rope 22, causing impurities to fall off the surface of the suspension rope 22.

[0031] It should be noted that the transparent frame 1, winding roller 21, suspension rope 22, ultrasonic depth sounder 24 and servo motor 27 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the ultrasonic depth sounder 24 and servo motor 27 can be powered by built-in power supplies. The specific power supply method can be selected according to the situation, which will not be elaborated here.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
