Description

Technical Field

[0001] The utility model relates to the technical field of water quality sampling, in particular to an unmanned boat for water quality sampling. Background Art

[0002] There are many aspects to water ecological environment governance, but river and lake pollution prevention and control is the key. From a spatial perspective, pollution from upstream and downstream and from left and right banks will converge in rivers and lakes. From a causal perspective, rivers and lakes are the direct carriers of water pollution emissions and water ecological damage. All problems such as insufficient infrastructure, excessive pollution discharge, and ecological damage are ultimately reflected in rivers and lakes. Therefore, it is necessary to sample the water quality of rivers and lakes. By testing the water quality of rivers and lakes, it can be determined whether the water ecological environment connected to rivers and lakes is polluted. In order to improve the efficiency of water quality sampling, unmanned boats are now mostly used, and water quality sampling devices are installed on the unmanned boats.

[0022] 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 of the embodiments.

[0023] See also Figures 1 to 4 The utility model provides a technical solution: an unmanned boat for water quality sampling, comprising a hull 1, an opening 101 opened on the hull 1, a support bar 2 fixedly connected between the inner walls of the opening 101, a motor 3 fixedly installed on the top of the support bar 2, an output end of the motor 3 passes through the support bar 2 and is fixedly connected to a turntable 4, a plurality of circumferentially distributed bottom blocks 5 are arranged below the turntable 4, an elastic component 6 is arranged between the bottom block 5 and the turntable 4, a sampling cup 7 is fixedly installed inside the bottom block 5, when the elastic component 6 is squeezed by the outside, the sampling cup 7 is caused to descend, and water flows into the sampling cup 7, thereby realizing the sampling work.

[0024] The inner wall of the opening 101 is fixedly connected with a support plate 9, on which a cylinder 10 is fixedly mounted. When the sampling cup 7 is sampling, the output end of the cylinder 10 is always in contact with the top of the positioning bar 63, pushing the positioning bar 63 down.

[0025] Start the motor 3 to drive the turntable 4 to rotate, and the turntable 4 drives the sampling cup 7 to perform circular motion. When the positioning bar 63 moves to below the output end of the cylinder 10, the motor 3 stops, the turntable 4 stops rotating, and then the cylinder 10 drives the elastic component 6 to make the sampling cup 7 descend. In this way, the sampling purpose of different sampling cups 7 can be achieved, sampling can be performed in different waters, and the reliability of sample data can be improved.

[0026] Specifically, the elastic component 6 includes two guide rods 61 fixed to the top of the bottom block 5. The upper ends of the guide rods 61 movably penetrate the turntable 4 and are fixedly connected with a positioning bar 63. A spring 62 is fixedly connected between the positioning bar 63 and the turntable 4. The spring 62 is sleeved on the guide rods 61.

[0027] The output end of the cylinder 10 pushes the positioning bar 63 downward, and the positioning bar 63 drives the bottom block 5 to descend through the guide rod 61, and finally the cup mouth of the sampling cup 7 enters below the liquid surface, and the water flows into the interior of the sampling cup 7 to achieve the sampling purpose. At this time, the spring 62 is in a compressed state; when the output end of the cylinder 10 retracts, the spring 62 releases its elastic force, pushing the positioning bar 63 upward, and finally the sampling cup 7 moves upward, realizing the resetting of the sampling cup 7.

[0028] A slot is provided on the top of the bottom block 5, and the slot is a circular groove structure. The lower end of the sampling cup 7 is inserted into the slot. A bolt 8 is threadedly inserted on the bottom block 5, and the threaded end of the bolt 8 is in contact with the sampling cup 7 to achieve fixed installation of the sampling cup 7. When the sampling cup 7 needs to be disassembled, the bolt 8 is loosened to remove the sampling cup 7 from the inside of the slot.

[0029] The motor 3 is a stepper motor that rotates at a fixed step angle. Each time a pulse signal is received, the stepper motor rotates at a fixed angle. Therefore, the rotation angle of the turntable 4 can be accurately controlled each time to ensure that the positioning bar 63 rotates to below the output end of the cylinder 10.

[0030] In addition, the opening 101 in the present application is a rectangular opening.
