DETAILED DESCRIPTION

[0024] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Example 1

[0026] like Figure 1-7 As shown, an aquatic biodiversity survey equipment includes a main body plate 1 and two storage cylinders 11 arranged below the main body plate 1, a lifting rod 8 and a lifter are arranged on the upper surface of the main body plate 1, and the lifter is arranged on the surface of the water carrier 9, a filter chamber 14 is arranged inside the storage cylinder 11, a fine filter screen 16 is penetrated through the bottom end surface of the filter chamber 14, a water suction pump 17 for generating a pressure difference for the fine filter screen 16 is arranged at the bottom end of the fine filter screen 16, the filter chamber 14 is connected to the outside through a water inlet 12, and a primary filter screen 13 is arranged at the inlet end of the water inlet 12, an annular storage chamber 15 is also arranged on the periphery of the filter chamber 14 of the storage cylinder 11, the filter chamber 14 is connected to the storage chamber 15, and a guide plate 18 is arranged at the connection point, and a collecting mechanism 5 for sweeping the organisms on the surface of the fine filter screen 16 into the storage chamber 15 is also arranged inside the filter chamber 14.

[0027] During operation, the water suction pump 17 generates suction, and a pressure difference is generated at both ends of the fine filter 16 to form a water flow. External water is filtered by the primary filter 13 and enters the filter chamber 14 from the water inlet 12, and then passes through the fine filter 16 and is discharged by the water suction pump 17.

[0028] In order to solve the problem of aquatic plants, an opening mechanism 2 is arranged on the periphery of the storage cylinder 11, wherein the opening mechanism includes a first motor 21, a rotating ring 22 driven by the first motor 21 is arranged on the outer surface of the storage cylinder 11, a vertical rod 23 is arranged on the surface of the rotating ring 22 and is in contact with the side wall of the storage cylinder 11, a plurality of levers 24 for pushing away the aquatic plants are arranged on the outer surface of the vertical rod 23, the lever 24 is hinged by multiple sections of hollow rods, a first straightening mechanism 3 for straightening the lever 24 is arranged inside the lever 24, a combing plate 7 for combing the lever 24 is arranged on the lower surface of the main body plate 1, the rotating ring 22 is embedded in the outer peripheral surface of the storage cylinder 11, and A swivel 22 is provided at both ends of the vertical rod 23, and a tooth groove is provided on the surface of the swivel 22 located at the upper end. A gear meshing with the tooth groove is provided at the output shaft end of the first motor 21. The end of the lever 24 is connected to the vertical rod 23 through a U-shaped plate 31. The first straightening mechanism 3 includes a sliding rod 32 which slides inside the lever 24 and is hinged by multiple sections of rods. The end of the sliding rod 32 extends to the inside of the U-shaped plate 31, and a push plate 35 is provided at the end of the sliding rod 32. A spring 34 is provided between the push plate 35 and the surface of the U-shaped plate 31 to push the sliding rod 32 to slide. The surface of the storage cylinder 11 is provided with a C-shaped first guide plate 4 corresponding to the push plate 35.

[0029] When the first motor 21 is driven, the rotating ring 22 rotates, and the rotating ring 22 drives the lever 24 to rotate through the vertical rod 23, and the water plants are moved to both sides. When the vertical rod 23 moves the water plants, the push plate 35 is supported by the first guide piece 4, and the spring 34 is in a compressed state. The slide bar 32 is pushed into the inside of the lever 24, so that the first hinge knot 25 at the hinge of the slide bar 32 is misaligned with the second hinge knot 33 on the surface of the lever 24, and the lever 24 is straightened. When the lever returns, the water plants on the surface of the lever 24 are combed and removed by the combing plate 7. In order to facilitate combing, the lever 24 can be bent at this time. Since the C-shaped first guide piece 4 has a notch, when the push plate 35 is not supported by the first guide piece 4, the spring 34 pushes the slide bar 32 to slide, so that the first hinge knot 25 is aligned with the second hinge knot 33, and the lever 24 can be bent freely. After passing through the combing plate 7, the push plate 35 is pushed up by the first guide piece 4 again to straighten the lever 24.

[0030] The collecting mechanism 5 is provided to prevent the surface of the fine filter 16 from being clogged. The collecting mechanism 5 includes a rotating drum 52 and a second motor 51 for driving the rotating drum 52 to rotate. A plurality of evenly distributed collecting plates 55 are provided on the periphery of the rotating drum 52. The collecting plates 55 are formed by hinged end to end of multiple hollow plates, and a second straightening mechanism 6 for straightening the collecting plates 55 is provided inside the collecting plates 55. A column 53 is provided on the bottom end surface of the filter chamber 14. The column 53 extends into the interior of the rotating drum 52, and a second guide sheet 54 for driving the second straightening mechanism 6 to operate is provided on the surface of the column 53.

[0031] Among them, the second straightening mechanism 6 has the same principle and structure as the first straightening mechanism. The second straightening mechanism 6 is supported or loses support through the second guide plate 54, so as to achieve the same straightening function as the slide rod 32. The difference from the lever 24 is that the lever 24 extends outward along the radius direction of the storage tube 11. In order to better scan the biological sample into the storage tube 11, the collection plate 55 is arranged to be inclined, so that when the collection plate 55 rotates, the organisms pushed by the collection plate 55 move to the outside of the collection plate 55, so that the organisms are concentrated at the end of the collection plate 55 away from the rotating cylinder 52, so that when the collection plate 55 passes through the guide plate 18, the collection plate 55 itself bends and passes through, and the organisms enter the storage cavity 15 through the guide plate 18.

[0032] The specific implementation method is as follows: the device is set at the bow of the water carrier 9, the water carrier 9 moves forward slowly, and pushed aside the water plants under the drive of the first motor 21, the negative pressure caused by the water suction pump 17 makes the water enter the water inlet 12, and then it is discharged to the bottom end of the storage tube 11 after passing through the fine filter 16, the second motor 51 is operated to rotate the collecting plate 55, and the blocked organisms on the surface of the fine filter 16 are swept into the storage chamber 15, and when sampling, the buckle net 151 is opened to take out the sample.

[0033] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
