Description

Technical Field

[0001] This utility model relates to the field of experimental device technology, and in particular to an experimental device for use in natural aquatic environments. Background Technology

[0002] Experimental devices in natural aquatic environments serve multiple purposes, primarily for scientific research, environmental monitoring, ecological assessment, pollution control, and the development of water treatment technologies. They help researchers better understand, protect, and improve the aquatic environment, while also providing support for the sustainable use of water resources.

[0003] Existing testing equipment for natural aquatic environments mainly consists of fixed and semi-fixed (pontoon) testing devices. Fixed testing devices fix the specimen to an underwater concrete base, with the specimen's height above the water varying seasonally. Semi-fixed (pontoon) testing devices mount the specimen on a pontoon and suspend it underwater, maintaining a fixed height above the water, but require a pontoon facility. The underwater concrete base and pontoon facilities require significant investment, have a long construction and preparation time, and are inconvenient to handle after temporary testing.

[0004] In inland waterways where water levels fluctuate significantly seasonally, underwater corrosion tests typically employ fixed or semi-fixed (pontoon) testing devices, which are costly and time-consuming, and make it difficult to quickly deploy samples in the waterway as needed. Therefore, an underwater testing device that can float on the water surface, is protected from impacts by floating objects, and is fixed to the shoreline is designed. Utility Model Content

[0028] Example 1

[0029] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present invention. This embodiment provides a test device for natural water environment. By setting a support column inside the frame and adding a crossbar on the support column, the sample is fixed on the crossbar, which facilitates sample placement and improves test efficiency.

[0030] Specifically, it includes a sample collection component 100, a first buckle 101 fixedly connected to the top of the sample collection component 100, a first chain 102 fixedly connected to the first buckle 101, a floating component 200 fixedly connected to the end of the first chain 102, a second buckle 201 fixedly connected to the lower sides of the floating component 200, a third buckle 202 fixedly connected to the upper sides of the floating component 200, and a second chain 203 fixedly connected to the third buckle 202.

[0031] Furthermore, the sample collection assembly 100 includes a frame 100a, which is composed of four long uprights, four long horizontal bars, and four short horizontal bars. Fixed rods 100b are fixedly connected to the two adjacent sides of the frame 100a. Two symmetrical support columns 100c are fixedly connected to the middle of the side of the frame 100a. Both support columns 100c have evenly arranged circular holes 100d. A horizontal bar 100e is fixedly connected inside the circular holes 100d.

[0032] Preferably, the frame 100a is a cuboid frame structure, the frame 100a is made of stainless steel angle steel, and the fixing rod 100b forms an isosceles triangle structure with the adjacent two sides of the frame 100a, and the frame 100a is reinforced by diagonal bracing through the fixing rod 100b.

[0033] The frame 100a is composed of fourteen 304 stainless steel angle bars with a length of ∠30×30×3. Among them, four long uprights with a length of 1200mm, four long horizontal bars with a length of 650mm, and four short horizontal bars with a length of 300mm form the test frame. Each front, rear, left, and right facade is alternately reinforced with fixed rods 100b for diagonal bracing. The fixed rods 100b are made of 304 stainless steel and have a size of 156mm×22mm×4mm. A support column 100c is vertically bolted to each of the left and right facades. The support column 100c has evenly distributed circular holes 100d. A horizontal bar 100e is passed through the support column 100. The horizontal bar 100e is a 304 stainless steel bar with one end bent by an L-shape and the other end threaded with a bow wire, used to connect the test specimens. ABS isolation columns were used to separate the samples. All 304 stainless steel angle steel overlaps were provided with φ10mm holes and fixed with M8×15 304 stainless steel bolts.

[0034] Example 2

[0035] Reference Figure 1 , Figure 2 and Figure 4 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment adds a horizontal tube and a net chain to the outer wall of the float to prevent the float from being damaged by floating objects on the water surface during the test.

[0036] Specifically, the floating assembly 200 includes a float 200a, which is fixedly connected to the frame 100a via a first chain 102. A horizontal tube 200b is fixedly connected to the float 200a in a circumferential array on its outer side, and a uniformly arranged mesh chain 200c is fixedly connected to the outer side of the horizontal tube 200b.

[0037] Furthermore, the float 200a has a cylindrical structure and is made of high-density polyethylene foam. The horizontal tube 200b is used to support and protect the float 200a from deformation after being subjected to external impact. The mesh chain 200c is made of 304 stainless steel, which can not only disperse the pressure of the underwater connected samples on the surface of the float 200a, but also protect the float 200a from being damaged by floating objects on the water surface during the test.

[0038] Preferably, the lower sides of the float 200a are symmetrically and fixedly connected with second buckles 201, and the end of the first chain 102 away from the frame 100a is fixedly connected to the second buckles 201.

[0039] The floating assembly 200 includes a solid high-density polyethylene foam float 200a with a diameter of φ600×900. The surface of the float 200a is bound with a 304 stainless steel mesh chain 200c with a width of 900mm and a length of 5650mm. This serves two purposes: firstly, to distribute the pressure load on the surface of the float 200a for the underwater series test specimens, i.e., the frame 100a, and secondly, to protect the float 200a from impact damage by floating objects during the test. The surface of the float 200a is also bound with a φ4mm 304 stainless steel mesh chain 200c in a cross or star pattern. Onshore workers need to package the outer wall of the float 200a by first fixing the horizontal tube 200b to the surface of the float 200a, and then placing the mesh chain 200c on the outside of the horizontal tube 200b, thus completing the assembly of the floating assembly 200.

[0040] Example 3

[0041] Reference Figures 1-4 This is the third embodiment of the present invention. Unlike the previous embodiment, in this embodiment, the sample is suspended inside the sample collection component at the bottom of the pontoon surrounded by the net chain by being bolted to a non-specific anchor point on the shore. The pontoon is suspended in the water, and there is no need to construct an underwater cement base or pontoon. This allows for low-cost and rapid sample placement.

[0042] Specifically, the top two sides of the frame 100a are symmetrically fixedly connected with first buckles 101, and first chains 102 are fixedly connected to the first buckles 101. The first chains 102 are made of stainless steel.

[0043] Furthermore, second buckles 201 are symmetrically fixedly connected to the lower sides of the floats 200a, and third buckles 202 are symmetrically fixedly connected to the upper sides of the floats 200a. The end of the first chain 102 away from the frame 100a is fixedly connected to the second buckle 201, and a second chain 203 is fixedly connected to the third buckle 202. The second chain 203 is also made of stainless steel.

[0044] Preferably, the end of the second chain 203 away from the buoy 200a is fixed at the anchor point.

[0045] Both the first chain 102 and the second chain 203 are 10-meter-long φ6mm 304 stainless steel chains. After the first chain 102 and the second chain 203 connect the sample collection component 100 and the floating component 200, the sample is fixed on the crossbar 100e. Then, the staff transports the entire device to the anchor point and slowly puts the sample collection component 100 into the water. At this time, the floating component 200 floats on the water surface. Then, the staff bolts the end of the second chain 203 away from the float 200a to the anchor point on the shore. The second chain 203 wraps around the stainless steel circumference of the anchor point 100mm from both ends and is bolted at least 6 points. All bolting points are fastened with M6 horseshoe-shaped stainless steel shackles to ensure the overall fixation of the device.
