Description

Technical Field

[0001] This utility model relates to the field of hydrological winch technology, specifically a multi-angle positioning device for hydrological winches. Background Technology

[0002] A hydrological winch is a specialized piece of equipment used in hydrological monitoring, marine surveys, and river channel exploration. It is primarily used for lowering and retrieving hydrological measuring instruments (such as current meters, water quality sensors, and water samplers). An encoder records the number of drum rotations in real time, converting this data into the instrument's lowering depth with centimeter-level accuracy. This system is suitable for scenarios requiring precise point-to-point measurements. Positioning the hydrological winch is essential.

[0003] Existing hydrological winches have a single angle, which is not conducive to the accurate adjustment of the position of measuring instruments. For example, in a novel electric hydrological winch disclosed in patent publication number CN214243597U, a platform is included, a pushing device is provided on the side of the platform, a moving device is provided on the bottom of the platform, and the hydrological winch body is fixedly installed on the top of the platform. The pushing device includes a mounting block, a U-shaped block is fixedly installed on the top surface of the mounting block, a long rod is provided through the top surface of the U-shaped block, a pushing handle is fixedly installed at one end of the long rod, a connecting block is fixedly installed at the other end of the long rod, a threaded rod is rotatably connected to the inner bottom surface of the U-shaped block, and a rotating handle is fixedly installed at the top of the threaded rod.

[0004] The aforementioned hydrological winch can be moved or its top rotation angle adjusted. However, it lacks a stable positioning and adjustment structure during the lowering and retrieval of hydrological measuring instruments, and its stability still needs improvement. To address these issues, a multi-angle positioning device for hydrological winches is proposed. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] 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.

[0025] Please see Figures 1-5 In this embodiment, a hydrological winch multi-angle positioning device includes a positioning frame 1, which includes a frame body 11.

[0026] The rotating assembly 2 includes a chassis 21, a positioning post 22 connected to the top of the chassis 21, a rotating sleeve 23 connected to the bottom of the frame 11 and rotatably engaged with the positioning post 22, a threaded sleeve 26 fixedly connected to one side of the frame 11, a positioning bolt 27 threadedly connected to the threaded sleeve 26, a positioning ring 28 connected to the top of the chassis 21, and a plurality of positioning holes provided on the positioning ring 28 for insertion into the bottom end of the positioning bolt 27; the chassis 21 can be installed on an existing fixed frame or on some mobile equipment for the installation of the device;

[0027] The cable take-up and release assembly 3 is installed on the frame 11. The positioning frame 1 is provided with a driving component for driving the cable take-up and release assembly 3 to take up or release the cable; a brake assembly 4 is used to limit the cable take-up or release assembly 3 after taking up or releasing the cable; and a support assembly 5, which includes a support frame 51 rotatably connected to the frame 11 and a telescopic frame body movably connected between the support frame 51 and the frame 11. The telescopic frame body is used to adjust the tilt angle of the support frame 51.

[0028] Using the above scheme, the frame 11 can rotate around the axis of the positioning column 22. Then, the positioning bolt 27 is rotated and inserted into the target positioning hole, which can restrict the rotation adjustment of the frame 11. By adjusting the length of the telescopic frame, the tilt angle of the support frame 51 can be adjusted and positioned. The wire take-up or wire release assembly 3 can be adjusted by the drive component to adjust the height of the hydrological measuring instrument. In conjunction with the rotating assembly 2 and the support assembly 5, the angle of the hydrological measuring instrument can be effectively adjusted and positioned.

[0029] Please see Figure 3 The take-up and unwind assembly 3 includes a winding roller 31 rotatably connected to the frame 11. One end of the winding roller 31 is connected to a large gear 32, and the other end of the winding roller 31 is connected to a protective disc 33. In actual use, an existing encoder, such as an optical encoder, can be installed on one side of the protective disc 33 to collect the number of rotations and angle of the winding roller 31.

[0030] When the drive unit is activated, the winding roller 31 rotates to reel in and unwind the cable, and the lowering height of the hydrological measuring instrument can be adjusted.

[0031] Please see Figure 2 and Figure 3 The driving component includes a rotating shaft 12 rotatably connected to the frame 11. A small gear 13 that meshes with a large gear 32 is connected to the rotating shaft 12. One end of the rotating shaft 12 extends to the outside of the frame 11 and is fixedly connected to a handle 14. Rotating the handle 14 on the frame 11 drives the rotating shaft 12 to rotate. The small gear 13 on the rotating shaft 12 meshes with the large gear 32 at one end of the winding roller 31, transmitting the rotation of the handle 14 to the winding roller 31.

[0032] Please see Figure 4The top side of the rotating sleeve 23 is connected to the support rod 24, and the bottom of the support rod 24 is connected to the roller 25. The top of the chassis 21 is provided with an annular track for the roller 25 to roll. When the rotating sleeve 23 rotates, the roller 35 rolls on the annular track, providing stable support and guidance for the rotation of the frame 11 and ensuring smooth angle adjustment.

[0033] Please see Figure 4 and Figure 5 The brake assembly 4 includes a support base 41 connected to one side of the frame 11, a brake disc 42 disposed on one side of the support base 41, and a central shaft 45 rotatably connected to the top of the support base 41. The brake disc 42 is connected to the support base 41 via a spring. Eccentric wheels 46 are fixedly connected to both ends of the central shaft 45. A lever 47 for rotating the central shaft 45 is connected to the central shaft 45. By adjusting the rotation of the central shaft 45 through the lever 47, the position of the eccentric wheel 46 can be adjusted. The longer end of the eccentric wheel 46 abuts against the brake disc 42. The brake disc 42 is in close contact with the protective disc 33, generating friction, thereby limiting the rotation of the winding roller 31 and achieving the limiting position after winding and unwinding.

[0034] Please see Figure 5 The spring component includes a guide cylinder 44 fixedly connected to the support base 41 and a guide post 43 fixedly connected to one side of the brake disc 42. The outer wall of the guide post 43 is slidably engaged with the inner wall of the guide cylinder 44, and the guide post 43 extends into the guide cylinder 44 to connect the spring. When the brake disc 42 is compressed, the spring will be stretched. The longer end of the eccentric wheel 46 is away from the brake disc 42 and loses compression. Under the tension of the spring, the brake disc 42 moves away from the protective disc 33.

[0035] Furthermore, the end of the eccentric wheel 46 that is away from the central shaft 45 and contacts the brake disc 42 is provided with a limiting plane; the outer side of the longer end of the eccentric wheel 46 more effectively abuts against the brake disc 42.

[0036] Please see Figure 2 The support assembly 5 includes a fixed rod 53 and two sets of adjusting rods 54 slidably connected to one side of the fixed rod 53. The end of the fixed rod 53 away from the adjusting rods 54 is rotatably connected to the support frame 51. The end of the adjusting rod 54 away from the fixed rod 53 is rotatably connected to a positioning rod 56 installed on the frame 11. The adjusting rod 54 is provided with several fixing holes. The fixed rod 53 is threaded with a locking bolt 55. The fixing holes correspond to the ends of the locking bolts 55. The top of the support frame 51 is rotatably connected to a guide wheel 52. By sliding the position of the adjusting rod 54 on the fixed rod 53, the length of the telescopic frame can be changed. After determining the tilt angle, the locking bolts 55 are tightened to fix the adjusting rod 54. The guide wheel 52 on the top of the support frame 51 can assist in guiding the cable, so that the entire device can work stably at different tilt angles.

[0037] The working principle of this utility model is as follows: the frame 11 can rotate around the axis of the positioning column 22, and then the positioning bolt 27 is rotated and inserted into the target positioning hole, which can restrict the rotation adjustment of the frame 11. By adjusting the length of the telescopic frame, the tilt angle of the support frame 51 can be adjusted and positioned. The wire take-up or wire release assembly 3 can be adjusted by the drive component to adjust the height of the hydrological measuring instrument. In conjunction with the rotating assembly 2 and the support assembly 5, the angle of the hydrological measuring instrument can be effectively adjusted and positioned.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
