DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0033] For example, see Figure 1-5The present invention provides a technical solution: a sample collection device for water conservancy detection, comprising a collection device 2, a connection frame 1 is fixedly connected to the top of the collection device 2, a zigzag tube 3 is fixedly connected to the bottom of the collection device 2, a collection tube 4 is fixedly connected to the bottom of the zigzag tube 3, a filter cover 5 is fixedly connected to the outer wall of the collection tube 4, and a driving mechanism 6 is fixedly connected to the outer wall of the connection frame 1;

[0034] The expulsion mechanism 6 comprises:

[0035] A first bracket 61, the first bracket 61 is fixedly connected to the outer wall of the connecting frame 1;

[0036] Sliding rod 62, the outer wall of sliding rod 62 is fixedly connected with the outer wall of first bracket 61, and a projection is set on the outer wall of sliding rod 62 relative to the position of impact rod 67, and then impact rod 67 rotates to intermittently impact the projection of sliding rod 62, and when the two are squeezed, it will drive motor 66 to descend, and motor 66 is connected with collection tube 4 through second bracket 65, so that collection tube 4 shakes, and when collection tube 4 shakes, part of water plants adhered to filter cover 5 will fall off, and the shaking of collection tube 4 will be used to make part of water plants on filter cover 5 fall off, thereby reducing the influence of water plants on sample collection;

[0037] The limiting rod 63 is slidably connected to the outer wall of the sliding rod 62 .

[0038] The bottom of the limiting rod 63 is fixedly connected to a spring 64 , and the bottom of the spring 64 is fixedly connected to a motor 66 .

[0039] The outer wall of the motor 66 is fixedly connected to the second bracket 65 , and the bottom of the second bracket 65 is fixedly connected to the outer wall of the collection tube 4 .

[0040] The outer wall of the collection tube 4 is rotatably connected to a bearing 69, which utilizes the kinetic energy generated by the motor 66 during the rotation process to drive the bearing 69 to rotate. The bearing 69 will drive the circular tube 9 to rotate during the rotation process. The rotation diameter at the air flow port 10 is larger than the rotation diameter at the circular box 8. The difference in rotation diameters results in different flow rates of the rotating airflow at different positions. Combined with the Bernoulli principle, water is guided to flow onto the filter cover 5. The flow of water will wash away the aquatic plants and fish and shrimps near the filter cover 5. The impact of the water flow is utilized to reduce the aquatic plants and fish and shrimps on the filter cover 5, thereby reducing the influence of the aquatic plants on sample collection. The outer wall of the motor 66 is fixedly connected to a collision rod 67 via a rotating shaft.

[0041] A belt 68 is sleeved between the rotating shaft of the motor 66 and the outer wall of the bearing 69 , and a round tube 9 is fixedly connected to the outer wall of the bearing 69 .

[0042] The outer wall of the circular tube 9 is fixedly connected with a circular box 8 , and the outer wall of the circular tube 9 is provided with an air flow opening 10 .

[0043] When in use, the connecting frame 1 is connected to a desired position, the connecting frame 1 is located on the water surface, the collecting device 2 is placed in the water through the zigzag tube 3 and the collecting tube 4, and the collecting tube 4 is provided with a filter cover 5, which intercepts fish, shrimp and aquatic plants in the water;

[0044] Combined with Figure 2 , Attachment Figure 3 and attached Figure 4 As shown, the collection tube 4 is connected to the connecting frame 1 through the bending tube 3. The bending tube 3 can be bent so that the angle of the collection tube 4 can be changed. The motor 66 is powered on to drive the impact rod 67 to rotate. The outer wall of the slide bar 62 is provided with a protrusion relative to the position of the impact rod 67. Then, the impact rod 67 rotates and hits the protrusion of the slide bar 62 intermittently. When the two are squeezed, the motor 66 is driven to descend. The motor 66 is connected to the collection tube 4 through the second bracket 65, so that the collection tube 4 shakes. When the collection tube 4 shakes, part of the water plants adhered to the filter cover 5 will fall off.

[0045] The limiting rod 63 is slidably connected to the slide bar 62, and limiting grooves are set at the top and bottom of the slide bar 62 to prevent the limiting rod 63 from falling. The mutual compression between the impact rod 67 and the slide bar 62 will drive the motor 66 to descend, at which time the spring 64 will be stretched. Then, after the impact rod 67 rotates and passes through the protrusion of the slide bar 62, the elasticity of the spring 64 will pull the motor 66 to reset, and the motor 66 drives the collection tube 4 to swing through the second bracket 65.

[0046] Combined with Figure 5 As shown, the circular tube 9 is connected to the outer wall of the bearing 69, and the circular box 8 is arranged at the center of the collection tube 4. The motor 66 will also drive the bearing 69 to rotate through the belt 68 during the rotation process. The bearing 69 will drive the circular tube 9 to rotate during the rotation process. An air flow port 10 is opened on the outer wall of the circular tube 9, and a hole is opened on the outer wall of the circular box 8. The rotation diameter at the position of the air flow port 10 is larger than the rotation diameter at the position of the circular box 8. The difference in rotation diameter makes the rotating airflow at the position different. Combined with the Bernoulli principle, the greater the airflow velocity, the smaller the pressure. Therefore, the pressure at the hole position of the circular box 8 is squeezed toward the position of the air flow port 10, thereby guiding the water flow to the filter cover 5. The flow of water will wash away the aquatic plants and fish and shrimps near the filter cover 5.

[0047] For example 2, please refer to Figure 1-8 Based on the first embodiment, the present invention provides a technical solution:

[0048] The outer wall of the connecting frame 1 is fixedly connected with an impact mechanism 7, and the impact mechanism 7 includes a third bracket 72, and the third bracket 72 is fixedly connected to the outer wall of the connecting frame 1. The outer wall of the third bracket 72 is fixedly connected with a fan 71, and the fan 71 sucks air and transports it to the circular bin 73. The electric slider 76 blocks the rubber plate 75. The increase of gas in the circular bin 73 will cause gas compression. After the electric slider 76 passes through the rubber plate 75, the compressed gas in the circular bin 73 is ejected toward the relative position of the electric slider 76. The cyclic activity of the electric slider 76 continuously guides the airflow to be ejected. The airflow impacts the water to generate an undercurrent in the water, thereby expelling fish and shrimps. The undercurrent in the water is guided by the impact of the gas, which reduces the influence of fish and shrimps on sample collection. The water flow impacts the filter cover 5, which will clean the aquatic plants on the filter cover 5. The compressed gas is impacted into the water, and the airflow guides the water flow to clean the filter cover 5.

[0049] A circular bin 73 is fixedly connected to the bottom of the fan 71, a square bin 74 is fixedly connected to the bottom of the circular bin 73, a rubber plate 75 is fixedly connected to the inner wall of the circular bin 73 at the position of the square bin 74, a slide rail 77 is fixedly connected to the inner wall of the square bin 74, and an electric slider 76 is slidably connected to the outer wall of the slide rail 77.

[0050] When in use, the fan 71 is set on the connecting frame 1, so the fan 71 is located on the water surface. The fan 71 is powered on to start sucking air and transporting it to the circular bin 73. The electric slider 76 is powered on to start and moves on the square bin 74. When the electric slider 76 moves to the position of the rubber plate 75, the electric slider 76 will block the rubber plate 75. At this time, the fan 71 continues to guide the gas into the circular bin 73. The increase in the gas in the circular bin 73 will produce gas compression. After the electric slider 76 passes through the rubber plate 75, the compressed gas in the circular bin 73 is ejected toward the relative position of the electric slider 76. Then the cyclic activity of the electric slider 76 continuously guides the airflow to eject. The airflow impacts the water to generate an undercurrent, thereby expelling fish and shrimps. In addition, the water flow impacts the filter cover 5, which will clean the aquatic plants on the filter cover 5.
