Description

Technical Field

[0001] The invention relates to the technical field of freshwater shell vegetable collection, and in particular to a freshwater shell vegetable collection device and method suitable for the surface of a metal structure. Background Art

[0002] In recent years, with the development of my country's shipping and water diversion projects, the invasive species freshwater shellfish has gradually spread from the Pearl River Basin and the Yangtze River Basin to my country's northern basins. Its erosion of hydraulic structures and water pollution have had a great impact on hydropower stations and water diversion projects. At present, my country's research on the prevention and control of freshwater shellfish is still in its infancy. The conventional method is to scrape it off manually or mechanically after it attaches.

[0003] Investigations and studies have shown that freshwater weeds like to attach to the surface of metal hydraulic structures, such as metal pipes, pontoons, ship lifts, trash racks, etc. During the operation and management of the project, it is necessary to collect and remove freshwater weeds on the surface of metal hydraulic structures, mainly including two aspects: first, when the density of freshwater weeds on the surface of pontoons and trash racks is high, they need to be cleaned up in time to avoid secondary reproduction and death that pollutes the water quality; second, in the process of freshwater weed prevention and control research, freshwater weeds need to be collected to carry out observation and research on their habits.

[0004] At present, freshwater shellfish are generally scraped away manually with handheld shovels, long-handled scrapers or scraper nets, and collected manually by small boats near pontoons, trash racks and other structures. However, manual scraping and collection are inefficient, pose great safety hazards, and the collection and removal area is limited.

[0005] In view of this, how to provide a device that is convenient for scraping and collecting freshwater shell vegetables on the surface of metal hydraulic structures is a technical problem that people in this field urgently need to solve. Summary of the invention

[0011] The scraper assembly is provided with a movable track fixedly disposed on the inner side surface of the micro-motion metal sleeve, the movable tracks on two adjacent micro-motion metal sleeves are located in corresponding positions, and the scraper assembly can move along a plurality of the movable tracks.

[0012] Furthermore, the connecting rod assembly comprises:

[0013] First connecting rod;

[0014] A second connecting rod, the first connecting rod and the second connecting rod are hinged, and one end of the second connecting rod is fixedly connected to the first long straight metal sleeve;

[0015] A reversing rod, wherein a plurality of clamping holes are provided on the reversing rod, and a first clamping nail and a second clamping nail are respectively provided on the first connecting rod and the second connecting rod. The reversing rod is fixedly connected to the first connecting rod through the clamping hole and the first clamping nail, and is fixedly connected to the second connecting rod through the clamping hole and the second clamping nail.

[0016] Furthermore, both ends of the scraper assembly are connected to the driving gear through a third connecting rod, a rack is defined in the movable track, the driving gear is meshed with the rack, and when the driving gear rotates, the scraper assembly moves along the movable track.

[0017] Furthermore, the scraper assembly comprises:

[0018] The scraper body is fixedly connected to the third connecting rod, a double-layer scraper is arranged at the lower end of the scraper body, and the double-layer scraper is arranged at intervals up and down. A power supply is arranged inside the scraper body, and the power supply supplies power to the driving gear.

[0019] Furthermore, the double-layer scraper includes an upper blade body and a lower blade body. The angle between the upper blade body and the horizontal plane is 15° and the tail end of the upper blade body is connected to the scraper body through a spring. The angle between the lower blade body and the horizontal plane is 10° and the tail end of the lower blade body is fixedly connected to the scraper body. The lengths of the upper blade body and the lower blade body are both 20 cm, with a spacing of 1 mm.

[0020] Furthermore, it also includes:

[0021] A sealing net, a connection part is arranged near the top of the scraper body, the sealing net is connected to the connection part, the sealing net and the net bin form a collecting net bag, and the freshwater shell vegetables cut and detached by the double-layer scraper can fall into the collecting net bag.

[0022] Furthermore, two adjacent micro-motion metal sleeves are connected via a wheel axle with a limiter.

[0023] The present invention also discloses a method for collecting freshwater shell vegetables suitable for the surface of metal structures, and the method comprises the following steps:

[0024] S1: The operator holds the first connecting rod and covers the net warehouse above the freshwater shellfish. The first long straight metal sleeve and the second long straight metal sleeve are fixed on the surface of the metal structure by using the first magnet and the second magnet. The second long straight metal sleeve automatically adjusts the movable gap between the two adjacent micro-motion metal sleeves according to the shape of the metal structure surface until the second long straight metal sleeve is adapted to the shape of the metal structure surface;

[0025] S2: The driving gear starts and moves along the rack, driving the scraper assembly to move along the length direction of the second long straight metal sleeve. During the movement, the upper blade body first contacts the freshwater shellfish, and the spring is bent and twisted by the freshwater shellfish, and the upper blade body rotates together. The scraper assembly continues to move, and the head of the freshwater shellfish is lifted by the upper blade body, and the lower blade body cuts the byssus part of the freshwater shellfish, and the freshwater shellfish is cut;

[0026] S3: The sealing net moves along with the scraper assembly along the length direction of the second long straight metal sleeve. During the movement, the sealing net and the net bin form a collecting net bag to collect the freshwater shell vegetables cut in step S2. When the scraper assembly finishes cutting the freshwater shell vegetables, the operator stretches the first connecting rod outward to separate the first long straight metal sleeve and the second long straight metal sleeve from the surface of the metal structure to recover the freshwater shell vegetables.

[0027] Further, in step S2, when the driving gear moves to the movable gap between two adjacent fine-motion metal sleeves, the driving gear is meshed with the racks of the two fine-motion metal sleeves at the same time.

[0028] The present invention discloses the following technical effects:

[0029] 1. There is a movable gap between adjacent micro-motion metal sleeves. When the second long straight metal sleeve is adsorbed on the surface of a metal structure, such as a metal pipe, a pontoon, a ship lift, a trash rack, etc., the shape of the second long straight metal sleeve can be adaptively adjusted according to the actual surface shape to make it compatible with the surface of the metal structure, so that the present application can be applied to various usage scenarios with high flexibility.

[0030] 2. In the process of collecting and removing freshwater shell vegetables, the scraper assembly is automatically driven by the driving gear and the process does not require manual operation. Therefore, when the present application is working, it is only necessary for the net bag frame to reach the position of the freshwater shell vegetables. The operator is not required to be able to touch the freshwater shell vegetables. By adding a connecting rod assembly, the collection and removal range of the freshwater shell vegetables is expanded, thereby improving the safety of the collection and removal of freshwater shell vegetables.

[0031] 3. The scraper assembly is equipped with a sealing net, which can be used in conjunction with the net bin to collect the freshwater shell vegetables into the collection net bag while the scraper assembly removes the freshwater shell vegetables, thereby improving the collection efficiency.
