Description

Technical Field

[0001] The invention relates to the technical field of water sampling, in particular to a meteorological monitoring precipitation sampler. Background Art

[0002] The meteorological monitoring system monitors and reports indicators that reflect meteorological quality to determine meteorological environmental data such as rainfall, wind speed and direction in the area; In the field of meteorological detection, a precipitation sampler is used to sample rainwater. The existing precipitation sampler collects rainwater through a bell mouth and flows it into a sampling bottle. In order to facilitate taking out, the existing sampling bottle is usually placed on a placement seat with a gap between the bell tube and the sampling bottle. Therefore, it is easy to cause the water inside the sampling bottle to overflow when it is full. To address the above problems, we propose a precipitation sampler for meteorological monitoring. Summary of the Invention

[0003] In response to the above problems, the present invention provides a meteorological monitoring precipitation sampler. With the assistance of an annular concave-convex plate, the upper and lower moving parts are inserted into the arc grooves on the circular plate and the gear plate at intervals to control the rotation and rise of the circular plate. When the circular plate rotates, multiple sampling bottles can be sampled separately. When the circular plate rises, water overflow is prevented with the assistance of an elastic sealing tube mechanism.

[0004] The present invention provides a meteorological monitoring precipitation sampler, comprising a placement box, wherein a water quality collection mechanism is provided in the placement box; the water quality collection mechanism comprises a shaft, a circular plate, a rotating disk, an up-and-down moving part, and an annular concave-convex plate; The shaft is rotatably connected to the placement box, the circular plate is fixed to the inside of the placement box, the upper end of the shaft is rotatably connected to the bottom wall of the circular plate, and a gear plate is coaxially fixed to the shaft, and arc grooves are provided on the gear plate and the circular plate. The arc grooves on the gear plate and the arc grooves on the circular plate are spaced apart, and the turntable is threadedly connected to the shaft, and the up and down moving parts are slidably connected to the turntable and are opposite to the arc grooves. The up and down moving parts rotate in a circle on the annular concave-convex plate; the annular concave-convex plate is fixed to the placement box and is concentrically arranged with the shaft, and the highest point of the annular concave-convex plate is the straight part.

[0005] The top wall of the placement box is connected to an elastic sealing pipe mechanism, which includes pipe one, pipe two, and a spring. Pipe one is fixedly connected to the placement box, and pipe two is sealingly and slidingly sleeved on the surface of pipe one. The spring is sleeved on the surface of pipe one and is pressed against the top of pipe two. A pie-shaped plate A is fixedly connected to the bottom end of the inside of pipe one. There are two pie-shaped plates A, which are symmetrically arranged with the center position of pipe one as the reference. A connecting plate is fixedly connected to the inner wall of pipe two, and the connecting plate passes through pipe one. A movable groove is provided on pipe one, and the connecting plate moves up and down in the movable groove. A pie-shaped plate B is fixedly connected to the connecting plate, and there are two groups of pie-shaped plates B, which are symmetrically arranged with the center of pipe two as the reference. Piece-shaped plate B is arranged in pipe one, and pie plate A and pie plate B are staggered in the vertical direction. When pie plate A and pie plate B are fitted together, the pipe is blocked.

[0006] Beneficial effects of the present invention: The present invention provides a meteorological monitoring precipitation sampler: 1. With the help of the annular concave-convex plate, the up and down moving parts are inserted into the arc grooves on the circular plate and the gear plate at intervals, which controls the rotation and rise of the circular plate at intervals, driving the rise of the sampling bottle. The sampling bottle can be rotated and raised at intervals through one drive, reducing the waste of resources. 2. When the circular plate rotates, multiple sampling bottles can be sampled separately. When the circular plate rises, the sampling bottles rise, and the sampling bottles squeeze the elastic sealing tube mechanism upward, so that the pancake plate B in the elastic sealing tube mechanism moves upward and does not fit with the pancake plate A, forming a water outlet channel for sampling. After sampling, the sampling bottle moves downward, and the pancake plate B moves downward under the pressure of the spring, cooperating with the pancake plate A to block the water outlet and prevent water leakage.

The pipe 12 is connected to the trumpet 10 and extends to the outside of the placement box 1. The pipe 213 is sealed and slidably sleeved on the surface of the pipe 12. The spring 14 is sleeved on the surface of the pipe 12 and is pressed against the top of the pipe 213. The bottom end of the side wall of the pipe 213 is fixed with a ring plate 26, and the bottom end of the inner bottom of the pipe 12 is fixed with a pie-shaped plate A15. Two plates A15 are provided, which are symmetrically arranged with the center position of pipe 12 as the reference.

[0015] A driving motor 22 is fixedly connected to the interior of the placement box 1 , and a pinion 23 is fixedly connected to the output end of the driving motor 22 . The pinion 23 is engaged with the gear plate 8 , and the diameter of the pinion 23 is smaller than the diameter of the gear plate 8 .

[0016] A sealing door panel 25 is rotatably connected to the front end surface of the storage box 1 .

[0017] Principle of the present invention: When in use, the sealing door panel 25 is opened, and the sampling bottles are placed in the limiting rings 24 on the turntable 5 respectively. The lower end of the vertical rod 19 is arranged in the arc groove 9 on the gear plate 8 and contacts the side end wall of the arc groove 9. The driving motor 22 is started, driving the small gear 23 to rotate, driving the gear plate 8 to rotate, and driving the shaft 3 to rotate. The diameter of the small gear 23 is smaller than the diameter of the gear plate 8, so that the gear plate 8 can rotate slowly. The gear plate 8 rotates, driving the up and down moving parts 6 to rotate in a circular manner, driving the turntable 5 to rotate, and driving the sampling bottles to rotate to the lower end of the elastic sealing tube mechanism 11. The sampling bottle mouth is opposite to the water outlet of the pipe 12, and the diameter of the sampling bottle mouth is larger than the water outlet diameter of the pipe 2 13. When the up-and-down moving member 6 rotates in an annular manner, the moving ball 21 in the up-and-down moving member 6 moves in an annular manner from the lowest point of the annular concave-convex plate 7 to the straight portion 18, and the moving ball 21 is pushed upward. The upper part of the vertical rod 19 slowly enters the arc groove 9 on the circular plate 4 and moves in the arc groove 9, gradually contacting the side end wall of the arc groove 9. The lower part of the vertical rod 19 is completely disengaged from the arc groove 9 on the gear plate 8. When the shaft rod 3 continues to rotate, since the shaft rod 3 is threadedly connected to the turntable 5, the turntable 5 moves upward at this time (the vertical rod 19 is hit by the side end wall of the arc groove 9 and cannot continue to rotate), causing the turntable 5 to move upward. The disk 5 cannot rotate, so the rotation of the shaft 3 will cause the turntable 5 to move upward), driving the sampling bottle upward. The sampling bottle moves upward and presses against the ring plate 26, which pushes up the pipe 2 13, driving the connecting plate 16 and the pie-shaped plate B27 fixed to the connecting plate 16 to move upward. The two pie-shaped plates A15 are separated from the other two pie-shaped plates B27. The rainwater collected by the trumpet 10 enters the sampling bottle through the pipe 12. Because the sampling bottle is pressed against the ring plate 26, the sampled water is prevented from flowing out. When the water in the sampling bottle is full, no water will flow out into the storage box 1. The driving motor 22 is an interval timing motor. After a period of time, the driving motor 22 is turned on, driving the small gear 23 to rotate, driving the gear plate 8 to rotate, driving the shaft 3 to rotate, and the shaft 3 is threadedly connected to the turntable 5. The rotation of the shaft 3 drives the turntable 5 to move downward, and the sampling bottle moves downward. The top of the sampling bottle gradually leaves the ring plate 26. Under the extrusion force of the spring 14, the pipe 2 13 moves downward, driving the connecting plate 16 to move downward, and then driving the two pie-shaped plates B27 fixed to the connecting plate 16 to move downward. Cooperating with the other two pie-shaped plates A15, the water outlet of the pipe 12 is blocked to prevent rainwater in the trumpet tube 10 from overflowing when the sampling bottle is separated from the ring plate 26; When the turntable 5 moves downward, the lower part of the vertical rod 19 extends into the arc groove 9 on the gear plate 8 and rotates in a circle in the arc groove 9. The upper part of the vertical rod 19 gradually comes out of the arc groove 9 on the circular plate 4, and the lower part of the vertical rod 19 contacts the side end of the inner wall of the arc groove 9 on the gear plate 8 to take a water sample from the next sampling bottle.

[0018] In the process of the moving ball 21 rising from the concave part of the annular concave-convex plate 7 to the flat part 18, the lower end of the vertical rod 19 gradually comes out of the arc groove 9 on the gear plate 8 until it is completely separated, and the upper end of the vertical rod 19 gradually inserts into the arc groove 9 on the circular plate 4, and gradually approaches and contacts the side wall of its end. When the moving ball 21 moves from the flat part 18 to the adjacent concave part, the turntable 5 moves up and down, and the upper end of the vertical rod 19 gradually comes out of the arc groove 9 on the circular plate 4 until it is completely separated, and the lower end of the vertical rod 19 gradually inserts into the arc groove 9 on the gear plate 8, and gradually approaches and contacts the side wall of its end.

[0019] Although the present invention has been disclosed above in terms of preferred embodiments, it is not intended to limit the present invention. Anyone familiar with this technology can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the authorization requirements.
