Description

Technical Field

[0001] This utility model relates to an artificial attachment test device for mussels, belonging to the field of mussel control technology. Background Technology

[0002] When pumped-storage power stations are built at sea, marine organisms such as mussels can parasitize the concrete structure, causing damage. However, research on the erosion resistance of pumped-storage power station concrete requires mussel-induced concrete damage experiments, which involve artificially attaching mussels to concrete specimens. The artificial attachment test involves restricting the mussel's position and measuring the number of byssal threads secreted by the mussel on the material surface and the adhesion strength to assess its affinity for or aversion to that material.

[0003] In existing technologies, the artificial attachment test requires the mussels to be manually attached to concrete specimens. However, current methods involve manually fixing them with wires, which is extremely inconvenient, inefficient, and prone to causing unstable attachment that allows the mussels to escape or excessive force that could injure or kill them. Therefore, we propose an artificial attachment test device for mussels. Utility Model Content

[0004] The purpose of this invention is to provide a mussel artificial attachment test device that is simple to operate and convenient to use, effectively reducing the time and labor costs of conducting mussel artificial attachment tests, and playing a significant auxiliary role in the research and development of concrete for pumped storage power stations to cope with mussel erosion.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a mussel artificial attachment test device, comprising a test piece, which is made of concrete. Each concrete test block is coated with a different material to be studied and tested to form a test piece. Mussels are placed on the test piece. The surface of the test piece has symmetrical perforations along the center line. Fixing components are inserted into the perforations from bottom to top. Fixing ropes are provided on the surface of the mussels. The two ends of the fixing ropes are detachably installed on the tops of two fixing components that are symmetrically positioned. The fixing ropes fix the mussels to the upper surface of the test piece.

[0006] The aforementioned artificial attachment test device for mussels has at least four perforations, which are symmetrically distributed in pairs on both sides of the mussel for easy fixation and more stable fixation.

[0007] In the aforementioned artificial attachment test device for mussels, each of the fixing ropes is provided with a cloth bag in the middle, which covers the top of the mussel. The cloth bag increases the contact area and makes the fixation more secure.

[0008] In the aforementioned artificial attachment test device for mussels, the cloth bag is provided with an anti-slip pad on the contact surface between the cloth bag and the mussel to increase friction and make the fixation more stable.

[0009] The aforementioned artificial attachment test device for mussels includes a fixing component comprising a column, a retaining edge, and a cap. The bottom end of the column is provided with a retaining edge, which engages with the bottom of a perforation. The top end of the column passes through the perforation and is provided with a threaded portion. The inner wall of the cap is provided with a thread corresponding to the threaded portion. The cap covers the threaded portion of the column from top to bottom. An ear plate is vertically provided on the upper surface of the column. The ear plate has a rope-passing hole in the horizontal direction. A limiting hole corresponding to the ear plate is provided in the middle of the upper wall of the cap. The ear plate is inserted into the limiting hole. The end of the fixing rope passes through the rope-passing hole and is fixed through the limiting hole.

[0010] In the aforementioned artificial attachment test device for mussels, the surface of the cap 9 is provided with anti-slip texture to facilitate rotation of the cap 9.

[0011] Compared with existing technologies, this utility model uses a highly elastic fixing rope for fixation, and the connection structure design is novel, making it simple and convenient to operate. It can effectively fix the mussels while avoiding problems such as the mussels escaping due to loose fixation or being damaged by excessive fixation. It effectively reduces the time and labor costs of conducting artificial mussel attachment tests, and plays a significant auxiliary role in the research and development of concrete to combat mussel erosion in pumped storage power stations.
