The whole device is huge in volume, slow in sampling speed during small-scale sampling or preliminary environmental detection, inconvenient to transfer the device, and the sampled water body is not preliminarily filtered, and impurities in the water are easy to affect subsequent detection. Content of the Utility Model

[0004] The main purpose of the utility model is to provide an automatic sampling device for ecological water bodies, aiming to sample water bodies flexibly and quickly.

[0005] To achieve the above object, an automatic sampling device for ecological water bodies proposed by the utility model includes a housing, a filtering structure and a control system:

[0007] The filtering structure is connected to the inner wall of the housing, the filtering structure is located below the liquid suction port, and a storage box is connected below the filtering structure; and

[0008] The control system includes a liquid level sensor, a cylinder and an airbag. The liquid level sensor is connected to the housing and the storage box, the liquid level sensor is electrically connected to the cylinder, the cylinder is communicated with the airbag, and the airbag is located below the liquid suction port.

[0009] In an embodiment of the present application, the housing is provided with installation holes oppositely, the negative pressure assembly passes through the installation holes and is drivingly connected to a motor, a floating plate is circumferentially convexly provided on the outer wall of the housing, the floating plate is located between the installation hole and the liquid suction port, and the motor and the cylinder are both connected to the floating plate.

[0010] In an embodiment of the present application, a limiting seat is circumferentially protruded on the inner wall of the housing. The width of the limiting seat gradually increases along the downward extending direction to form an abutting surface. One end of the filtering structure abuts against the abutting surface, and the end of the filtering structure away from the abutting surface is screwed to the housing.

[0011] In an embodiment of the present application, a limiting piece and a locking piece are circumferentially protruded at one end of the housing away from the negative pressure assembly. The filtering structure is screwed to the inner wall of the limiting piece, and the storage box is clamped between the limiting piece and the locking piece.

[0012] In an embodiment of the present application, two locking pieces are oppositely provided, and a locking bolt is provided between the circumferences of two adjacent locking pieces.

[0013] In an embodiment of the present application, a plurality of liquid suction ports are provided. The plurality of liquid suction ports are circumferentially spaced apart on the housing and are located at the same horizontal height.

[0014] In an embodiment of the present application, the negative pressure assembly includes a U-shaped rod, a driving rod, and a piston:

[0015] The U-shaped rod passes through the housing. The end of the U-shaped rod is drivingly connected to the motor, and the end of the U-shaped rod away from the motor is rotatably connected to the mounting hole;

[0016] The driving rod is rotatably connected to the bottom of the U-shaped rod; and

The floating plate enables the device to float on the water surface, and the liquid suction port is in the water. Below the liquid suction port, a filtering structure is installed inside the housing, which can initially filter out impurities in the water, such as leaves, branches, etc., to avoid these sundries interfering with subsequent detections. Below the filtering structure, there is a storage tank for collecting water. The outer wall of the storage tank is connected with a liquid level sensor, and the other end of the liquid level sensor is connected to a cylinder. The cylinder is arranged on the floating plate. When the liquid in the storage tank reaches a certain height, the liquid level sensor will send signals to the motor and the cylinder, causing the negative pressure assembly to stop operating and no longer collect water quickly. And the cylinder will inflate an airbag provided on the outer wall of the housing below the liquid suction port, causing the liquid suction port to leave the water body, and the device stops collecting. The entire device can be fished out of the water. By loosening the locking bolts and removing the storage tank, the automatic sampling of the water body can be completed.

[0032] Reference Figures 1 to 3 Figures 1 to 3 , in an embodiment of the present utility model, an automatic sampling device for ecological water bodies proposed includes a housing 1, a filtering structure 3, and a control system 5. The housing 1 is provided with a liquid suction port 11 around it. A movable plate 111 is rotatably connected to the upper end of the liquid suction port 11. A negative pressure assembly 2 is rotatably connected to the inner wall of the housing 1, and the negative pressure assembly 2 is located above the liquid suction port 11; the filtering structure 3 is connected to the inner wall of the housing 1, and the filtering structure 3 is located below the liquid suction port 11. A storage tank 4 is connected below the filtering structure 3; the control system 5 includes a liquid level sensor 51, a cylinder 52, and an airbag 53. The liquid level sensor 51 is connected to the housing 1 and to the storage tank 4. The liquid level sensor 51 is electrically connected to the cylinder 52, and the cylinder 52 communicates with the airbag 53. The airbag 53 is located below the liquid suction port 11.

[0033] In an automatic sampling device for ecological water bodies of the present application, a plurality of liquid suction ports 11 are provided at the same horizontal height of the housing 1 of the sampling device for a faster sampling operation. A movable plate 111 is rotatably connected above the liquid suction port 11. The movable plate 111 can cooperate with the negative pressure assembly 2 to complete the sampling operation more quickly using the principle of negative pressure. An installation hole 12 is provided above the liquid suction port 11. A U-shaped rod 21 of the negative pressure assembly 2 is rotatably connected in the installation hole 12. One end of the U-shaped rod 21 passes through the housing 1 and is drivingly connected to a motor 13. A floating plate 14 is circumferentially convex between the installation hole 12 and the liquid suction port 11. The motor 13 is installed on the floating plate 14. The floating plate 14 can make the device float on the water surface, and the liquid suction port 11 can maintain the sampling operation in the water. A limiting seat 15 is provided on the inner wall of the housing 1. The limiting seat 15 is below the liquid suction port 11. The width of the limiting seat 15 gradually increases along the downward extending direction and finally forms an abutting surface 151. The abutting surface 151 abuts against the frame 31 of the filtering structure 3 to limit the position and make the structure more stable. A limiting piece and a locking piece 17 are provided at one end of the housing 1 away from the negative pressure assembly 2. The limiting piece is a whole ring, and its inner wall is provided with threads, which can cooperate with the threads on the outer wall of the frame 31 in the filtering structure 3 to fix the filtering structure 3. The outer wall of the limiting piece abuts against the inner wall of the storage tank 4 to cooperate with the locking piece 17 to seal and fix the storage tank 4 for convenient sampling. The structure of the locking piece 17 is two opposite arcs. The locking piece 17 is provided at the outer edge of the limiting piece. A locking bolt 171 is provided at the adjacent side of the locking piece 17. After initially fixing the storage tank 4, by tightening the locking bolt 171, the locking piece 17 abuts against the outer wall of the storage tank 4 to achieve the purpose of sealing.

[0034] Further, the negative pressure assembly 2 includes a U-shaped rod 21, a driving rod 22, and a piston 23. The U-shaped rod 21 is rotatably connected to the mounting hole 12, and one end passes through the mounting hole 12 and is drivingly connected to the motor 13. The bottom end of the U-shaped rod 21 is rotatably connected to the driving rod 22, and the driving rod 22 is connected to the piston 23. Driven by the motor 13, the piston 23 can move up and down. When the piston 23 moves upward, the air pressure in the housing 1 decreases, and water is pushed by the atmospheric pressure to quickly open the flap 111 and enter the housing 1. When the piston 23 moves downward, the piston 23 abuts against the liquid suction port 11 due to the pressure, and the outside water will not enter. Instead, the piston 23 compresses the air to make the water enter the storage tank 4 faster under the action of pressure through the filter screen 32 of the filtering structure 3 to complete the sampling operation.

[0035] Further, the control system 5 includes a liquid level sensor 51, a cylinder 52, and an airbag 53. The cylinder 52 is also connected to the floating plate 14. The cylinder 52 is connected to the airbag 53 through a trachea. The airbag 53 is arranged below the liquid suction port 11. One end of the liquid level sensor 51 passes through the floating plate 14 and is connected to the outer wall of the storage tank 4, and the other end is electrically connected to the motor 13 and the cylinder 52 respectively. When the water level in the storage tank 4 reaches the set height of the liquid level sensor 51, the liquid level sensor 51 will command the motor 13 to cut off the power, the water inlet speed decreases, and the cylinder 52 is activated to inflate the airbag 53, so that the airbag 53 floats out of the water surface, the liquid suction port 11 leaves the water body, and the sampling device stops working. Through these structures, water samples can be collected quickly and flexibly, and sundries can be filtered out by the way, making the relevant work more flexible, time-saving and labor-saving.
