Portable multi-drive-mode winch

Abstract

The invention provides a portable multi-drive-mode winch which comprises an installation support, and the installation support comprises a bottom plate and two vertical plates. The two vertical platesare arranged on the bottom plate and arranged in the width direction of the bottom plate in a spaced mode. The top of each vertical plate is of a semicircular structure, a plurality of cable guide wheels are arranged between the upper ends of the two vertical plates, the cable guide wheels jointly form a virtual semi-cylindrical mechanism, and each cable guide wheel is installed on the two vertical plates through a cable guide column. A driving wheel is arranged between the lower parts of the two vertical plates and is mounted between the two vertical plates through a rotating shaft; the first end of the rotating shaft is sleeved with a turbine, a worm is arranged on the vertical plate close to the first end of the rotating shaft, the worm is meshed with the turbine, and a driving port ofthe worm is of a standard hexagonal head structure. The portable multi-drive-mode winch can be compatible with an electric drive mode and a manual drive mode at the same time, and is more flexible touse, high in safety coefficient, small in size and light in weight.

Description

technical field [0001] The invention relates to the technical field of marine technical equipment and underwater towing system, in particular to a portable multi-drive mode winch. Background technique [0002] Portable underwater towed systems are widely used in the field of underwater detection. For example, a small side-scan sonar detection system is towed by a small boat, and the side-scan sonar tow body is deployed to a certain depth underwater through the tow cable, and the detection task of the set water area can be completed. This type of underwater towed system has the advantages of simple system, portable equipment, and low requirements for carrying platforms. Therefore, it is widely used in the field of underwater detection, especially in the detection of waters such as inland rivers, lakes and reservoirs. [0003] The portable underwater towing system mainly consists of underwater towing body, towing cable and land-based display and control equipment. Generally, ...

Problems solved by technology

However, this method not only increases the requirements for the working boat (needs to be equipped with electric power), but also increases the complexity and weight of the system, which will affect the lightness of the equipment

The manual winch is driven by manpower. Although it solves the safety hazard and tethering problem when there is no winch, it also solves the problem of high requirements for the platform of the electric winch, but there are still labor intensity, inconvenient cable arrangement, and damage to the cable. Lack of necessary protection and heavy equipment

[0005] Moreover, there are two types of winches in the prior art: single-drum and double-drum structures. When the single-drum winch is in use, when the cable is long, it is difficult to arrange the cable and cannot protect the cable well.

However, the equipment size and quality of the double-drum winch are relatively large, which increases the difficulty of installation and use of the winch.
