The problem that a water sampler and a ship are damaged due to the fact that the device possibly occupies part of a channel and a passing ship collides with a cantilever is solved, and the sampler can be always kept in a downward vertical state, so that the situation that a water sample is spilled due to inclination of the sampler can be avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of water sampling equipment, in particular to a novel cantilever water sampler. Background Art

[0002] In order to monitor the pollution of river water quality, many automatic monitoring stations have been built across the country. The automatic water quality monitoring stations need to automatically collect water about 0.5m below the river surface all year round. The existing sampling equipment includes trestle type, buoy type, cantilever type, floating bridge type, cable type, etc.

[0003] The existing cantilever water sampler directly extends the cantilever to the middle of the river. Although part of the cantilever is telescopic and can be retracted to shorten the length, even after retraction, part of the cantilever is still located above the river channel, thereby occupying part of the waterway. There is a high probability that passing ships will collide with the cantilever, causing damage to the water sampler and the ship. Utility Model Content

[0022] In order to drive the sampler 10 to rotate when the cantilever 7 rotates, so that the sampler 10 can always maintain a vertical state, a connecting frame 12 is fixedly connected to the left side of the bottom surface of the cantilever 7. The shape of the connecting frame 12 is U-shaped. The top of the first cylinder 8 is movably connected to the inner side of the connecting frame 12. A first through hole is opened on the rear side of the connecting frame 12. The first through hole has a bearing sleeve with a first connecting shaft 13. Both ends of the first connecting shaft 13 respectively penetrate the inner and outer sides of the connecting frame 12. The front end face of the first connecting shaft 13 is fixedly connected to the rear side of the outer surface of the first cylinder 8 and near the top.

[0023] In order to start the first connecting shaft 13 to rotate, a mounting plate 14 is fixedly connected to the rear side of the connecting frame 12 and near the top, and a second motor 15 is fixedly connected to the bottom surface of the mounting plate 14. The shaft of the second motor 15 is fixedly connected to the rear end surface of the first connecting shaft 13, and the second motor 15 is electrically connected to the control box 11.

[0024] In order to connect the front side of the first cylinder 8 to the connecting frame 12 and make the first cylinder 8 more stable in the connecting frame 12, a second rotating shaft 16 is connected to the front side of the outer surface of the first cylinder 8 and near the top with a bearing, and the front end face of the second rotating shaft 16 is connected to the front side of the inner side of the connecting frame 12 with a bearing.

[0025] In order to limit the connecting seat 5 so that the connecting seat 5 does not rotate with the screw rod 3, a slide groove 17 is fixedly connected to the middle of the top surface of the base 1, and a slider 18 is fixedly connected to the bottom surface of the connecting seat 5. The slider 18 is slidably connected in the slide groove 17.

[0026] In order to support the right end of the screw rod 3 , a right support plate 19 is sleeved on the right end bearing of the surface of the screw rod 3 , and the bottom surface of the right support plate 19 is fixedly connected to the right side of the top surface of the base 1 .

[0027] In order to support the left side of the bottom surface of the cantilever 7 from the bottom when the cantilever 7 is in a flat state, and to prevent the cantilever 7 from breaking due to excessive weight on the left side, a mounting groove 20 is opened on the left side of the inner cavity of the base 1, and a second cylinder 21 is fixedly connected to the mounting groove 20, and the right end of the second cylinder 21 extends to the outside of the right side of the mounting groove 20, and the second cylinder 21 is electrically connected to the control box 11, and a supporting plate 22 is fixedly connected to the right end of the second cylinder 21, and the top surface of the supporting plate 22 is in contact with the bottom surface of the cantilever 7.

[0028] Working principle: When the utility model is used, the device is first installed on the ground beside the river channel. When sampling, the first cylinder 8 is first controlled by the control box 11, and the first cylinder 8 pushes the connecting rod 9 to descend, and the connecting rod 9 drives the sampler 10 to descend, so that the sampler 10 samples the water in the river channel. After the sampling is completed, the first motor 4 is started by the control box 11, and the first motor 4 drives the screw rod 3 to rotate, and the screw rod 3 rotates to move the connecting seat 5 to the right, and the connecting seat 5 moves to the right to pull the transmission rod 6 to lift the top of the cantilever 7, and the cantilever 7 is transformed into a vertical state, so that the cantilever 7 is moved away from above the river channel and is no longer placed above the river channel, thereby preventing the ship from sailing in the waterway. The collision device solves the problem that the device may occupy part of the waterway and cause passing ships to collide with the cantilever 7, thereby damaging the water sampler and the ship. When the cantilever 7 rotates from horizontal to vertical, the control box 11 controls the second motor 15 to rotate, and the second motor 15 drives the first connecting shaft 13 to rotate counterclockwise, the first connecting shaft 13 drives the first cylinder 8 to rotate, the first cylinder 8 drives the connecting rod 9 to rotate, and the first connecting rod 9 drives the sampler 10 to rotate, so that the sampler 10 is always kept in a downward vertical state, and then the first cylinder 8 pushes the sampler 10 to descend, so that the water sample in the sampler 10 can be taken out, thereby preventing the sampler 10 from tilting and causing the water sample to spill.
