Description

Technical Field

[0001] The utility model relates to the fields of marine fouling organism investigation and anti-fouling material performance evaluation, and particularly relates to a fixing device for nuclear power fouling organism investigation and anti-fouling coating test plates. Background Art

[0002] Marine biological fouling poses a serious threat to the safe operation of nuclear power cold sources. When marine organisms attach to the interception nets of nuclear power cold sources, they will block the mesh holes, increase the resistance of the netting, and cause poor water flow. Severe biological fouling will greatly increase the weight of the interception net, leading to the sinking of the interception net, shortening its service life, and even losing its interception function. In addition, when marine organisms attach to the cold source water intake pipes and gratings, it will accelerate the corrosion of the grating metal. The high-density attached organisms on the water intake tunnel will fall off, threatening the safe operation of nuclear power units. In order to economically and effectively control the attachment of marine fouling organisms on nuclear power facilities, it is necessary to investigate and study the fouling organisms in the nuclear power water intake area and evaluate the anti-fouling performance of relevant anti-fouling materials. The commonly adopted research method is the sea area panel test, collecting fouling organisms, finding out the species composition, biological community structure and dynamic changes; coating anti-fouling coatings on the panels to prevent the attachment of fouling organisms, and detecting the anti-fouling performance of the anti-fouling coatings, so as to provide a reliable scientific basis for the prevention and control of marine fouling organisms in the nuclear power water intake area.

[0003] According to the requirements of the sea area panel test, some researchers have designed fixing devices for fouling organism investigation tests that are convenient for experimental research. However, these devices often have certain defects: in order to ensure the stability of the test plates, bolt assemblies are mostly used for fixing, and installation and disassembly require the aid of specific tools, increasing the operation time at sea. Moreover, the bolt structure is easily attached by fouling organisms and corroded by seawater. When placed in the marine environment for a long time, it is easy to cause the nuts to be unable to be removed, making it difficult to take out the test plates, or it is easy to damage the fouling organisms or anti-fouling coatings on the test plates during the strenuous operation, affecting the test results. Content of the Utility Model

[0007] The fixed frame is a cuboid frame structure, including four first cross beams, four second cross beams and four third cross beams; the four first cross beams extend along the length direction of the fixed frame, the four second cross beams extend along the width direction of the fixed frame and are connected between the ends of two adjacent first cross beams distributed front and back, and the four third cross beams extend along the height direction of the fixed frame and are connected between the ends of two adjacent first cross beams distributed up and down;

[0008] The fixed frame is provided with a plurality of fixing mechanisms arranged at intervals along its length direction. The fixing mechanism includes four fixing plates in the same plane. The four fixing plates are respectively arranged on the four first cross beams. Each fixing plate is provided with a perforation. Four positioning holes are provided on the test plate and can be opposite to the perforations of the four fixing plates. The first connecting piece passes through the perforation and the positioning hole at the same time to realize the connection between the test plate and the fixing plate.

[0010] In a preferred embodiment: the four fixing plates include two arranged on the top surfaces of the two first cross beams located below and two arranged on the bottom surfaces of the two first cross beams located above.

Description of the Drawings

[0019] Figure 1This is a structural schematic diagram of the present utility model.

[0020] Figure 2 It is Figure 1 the enlarged view of part A in Specific embodiments

[0021] Refer to Figures 1 to 2 a fixing device for nuclear power fouling organism investigation and antifouling coating test plates shown in the figure below. Through specific embodiments and in combination with the accompanying drawings of the specification, the technical solution of the present utility model will be further described:

[0022] A fixing device for nuclear power fouling organism investigation and antifouling coating test plates includes a fixing frame 1, a fixing plate 2, a test plate 3 and a connecting plate 4.

[0023] The fixing frame 1 is welded into a cuboid structure by four first cross beams 11, four second cross beams 12 and four third cross beams 13. The size of the first cross beam 11 is selected according to the number of test plates 3. At least two groups of test plates 3 are provided to ensure the number of parallel samples. The size of the second cross beam 12 is the same as the side length of the test plate 3. At this time, when the test plate 3 is placed in the fixing frame 1, it can be supported by the first cross beam 11, avoiding the test plate 3 from being suspended and increasing its stability.

[0024] The fixing plate 2 is arranged in the fixing frame 1. Each fixing plate 2 is provided with a through hole 21. Multiple fixing plates 2 can be provided according to test needs. A certain distance should be kept between adjacent fixing plates 2 to ensure the smooth flow of water between adjacent test plates 3. The test plate 3 is arranged on one side of the fixing plate 2. Each test plate 3 is provided with four positioning holes 31 corresponding to the through holes 21 of the fixing plate 2. The through holes 21 of the fixing plate 2 and the positioning holes 31 of the test plate 3 are connected by a connecting member 5, so that the test plate 3 is fixed in the fixing frame 1. Four fixing points, plus the support of the first cross beam 11 for the test plate 3, ensure the stability of the test plate 3. The first connecting member 5 is a single-core copper wire. The single-core copper wire has the advantages of corrosion resistance and flexibility, which can prevent corrosion or deformation due to long-term immersion in water, resulting in unstable connection of the device. Also, when replacing the test plate 3 each time, the staff can cut the copper wire with wire pliers and quickly remove the test plate 3, greatly shortening the offshore operation time.

[0025] On the midpoint positions of two first cross beams 11 and two second cross beams 12 on the same side of the upper and lower parts of the fixing frame 1, a connecting plate 4 is fixed. Each connecting plate 4 is provided with a connecting hole 41. When there is a need for test plate hanging at different water layers at the same station, multiple fixing frames 1 can be interconnected by using a second connecting member and connected by four connecting ropes, reducing the risk of rotation and entanglement of the fixing frames 1 at different water layers due to water flow scouring and ensuring the reliability of the test results. The second connecting member can be a stainless steel wire or a fastening bolt, which is convenient for the assembly and disassembly of the fixing frame.

[0026] The above are only the preferred embodiments of the present utility model, and thus the scope of implementation of the present utility model cannot be limited thereby. That is, equivalent changes and modifications made according to the scope of the patent application of the present utility model and the content of the specification should still fall within the scope covered by the patent of the present utility model.
