Description

Cage underwater cleaning equipment

Technical field The utility model is a kind of net cage underwater decontamination equipment used for cleaning nets and nets in the aquaculture industry, which belongs to the field of fishery machinery and equipment.

Background technology In the aquatic industry, in order to carry out the needs of penning, enclosing, blocking, and raising fish, it is necessary to arrange nets and nets in the water to enclose aquatic animals such as fish. The cycle of aquaculture is generally long, and nets and nets It needs to be soaked in water for a long time, which provides an excellent attachment base for the growth of various algae and other organisms. The increasing number of attached organisms on the nets has a serious impact on the internal and external water exchange of the net ring, causing There are a series of problems such as water quality corruption, deterioration of water body environment, force distortion of cage shape, etc. Therefore, it is necessary to effectively remove the attached organisms of the fouling nets and nets. At present, a kind of water that has been publicly used is used to remove the underwater steel surface of ships. The attachment device works with a simple rotating brush. It is very difficult to clean the flexible nets laid underwater with this device. Another method of operation is manual cleaning, with the help of ships berthing On the side of net clothes and nets, the operator holds a long brush to clean underwater objects. This method is simple and easy, but it is labor-intensive and the cleaning effect is poor. Another method is to use high-pressure water pumps to create high-speed water flow. When operating, aim the nozzle of the water gun at the part to be cleaned. This equipment uses water to push the cleaning brush to clean the netting and nets at the same time. In actual use, because the jet will be subjected to strong fluid resistance in the water, it is difficult to accurately align the nozzle with the cleaning part. Therefore, it is very limited in use, and in some special environments, the method of diving personnel diving underwater to implement cleaning has also been used, but the difficulty of operation and management is very large, and it is difficult to widely adopt.

Contents of the utility model Aiming at the deficiencies of existing equipment, the purpose of this utility model is to provide a new type of net cage underwater cleaning equipment to solve the problem of underwater cleaning of net clothing attachments in aquaculture net cages.

The brush assembly is driven by an underwater motor [1]. One end of the shaft of the underwater motor [1] is connected to a transmission mechanism [6]. 12], the second worm gear [16] are respectively connected with the brush assembly [3] through the worm gear shaft [8], when the operable underwater platform [2] is hoisted into the underwater operation, the underwater motor [ Driven by 1], the brush head [7] completes the sweeping on the plane of the net [21] to remove the attachments on the net [21]. The other end of the shaft of the underwater motor [1] is connected to an impeller [ 9], the impeller [9] rotates at high speed under the drive of the underwater motor [1], pushes the underwater platform [2] close to the netting [21], and at the same time causes the backward impact flow of the underwater platform [2] to eliminate Sweep the dirt under the brush from the net clothing [21], a storage bag can be installed at the rear portion of the impeller [9], for collecting the dirt under the brush.

The underwater platform [2] is driven by the underwater motor [1], and the brush head [7] performs a rolling motion on the plane of the net [21]. Brushing removes the dirt on the net clothing [21], and the brushing direction of the upper row of hairbrush assemblies [24] and the lower row of hairbrush assemblies [22] is opposite, and its action results make the net clothing [21] in a tense state. It is conducive to the flat development of the net [21] and solves the problem of twisting of flexible components. At the same time, the underwater platform [2] is propelled by the impeller [9] and attached to the plane of the net [21] to increase the brush head [ 7] The effect of brushing can improve the cleaning effect, and can solve the problem of underwater cleaning of net clothing attachments in breeding cages.
