Technical Field
[0001] The present invention relates to the technical field of lake ecological environment monitoring, and in particular to a lake ecological environment monitoring sampling device. Background Art
[0002] The sampling device is a device used to collect samples of lake water, bottom sediment and aquatic organisms in order to monitor and analyze the water quality, ecological conditions and pollutants of the lake.
[0003] When collecting water samples during lake ecological environment monitoring, the sampling tube on the traditional lake water sample collection device can only obtain water samples at a fixed depth of the lake each time. This sampling method has high limitations. If it is necessary to analyze the differences in ecological indicators of different water layers, the staff must adjust the depth of the sampling equipment multiple times and repeat the sampling operation. This is not only time-consuming and labor-intensive, reducing sampling efficiency, but also increasing manpower and equipment loss costs. At the same time, during multiple sampling processes, the dynamic changes in environmental factors may lead to inconsistent water sample collection times at different depths, making the collected water samples unable to truly reflect the ecological conditions of different water layers at the same time point, seriously affecting the reliability and effectiveness of the monitoring data.

When sampling water in a lake, the second self-locking motor 34 can be started according to the sampling requirements to drive the winding tube to rotate on the bracket 1, and the pull rope 35 can be unwound. Then, the electric telescopic rod 31 can be started to drive the sliding frame 32 to slide outward to a certain distance in the inner wall of the bracket 1. The pull rope 35 will slide in the guide wheel frame 36 to form a bracket 1 of a new length, which can transport the sampling tube 4 to positions at different distances from the shore, making it easier to sample water at different positions from the shore, improving sampling efficiency and effectiveness, and making the collected data more complete and effective. It should be noted that the electric telescopic rod 31 and the second self-locking motor 34 are both mature driving technology means and equipment in the existing technology, and their internal structure, connection method and principle will not be elaborated on.
[0045] Working principle: When collecting water samples during the ecological environment monitoring of lakes, the inner wall of one end of the bracket 1 can be set on the tree trunk at the edge of the lake, and then the threaded rod 5 is screwed to drive the abutment plate 6 to clamp and fix the tree trunk, so that the bracket 1 is at the edge of the lake, and then according to the sampling requirements, the second self-locking motor 34 is started to drive the winding tube to rotate on the bracket 1, and the pull rope 35 is unwound, and then the electric telescopic rod 31 is started to drive the sliding frame 32 to slide outward to a certain distance in the inner wall of the bracket 1, and the pull rope 35 will slide in the guide wheel frame 36 to form a bracket 1 of a new length, which can transport the sampling tube 4 to positions at different distances from the shore, and put the sampling tube 4 into the water to a certain height and lock it, and take the sample. When sampling, one end of the block 284 will be inserted into the circular groove 287, so that the several water outlet holes 283 on the groove rod 281 and the several water outlet holes 283 on the rotating rod 282 are in a completely staggered and closed state, and then the first self-locking motor 291 is started to drive the gear 292 to rotate, thereby driving the gear ring block 293 and the annular cover 21 to rotate and self-lock on the outer surface of the sampling tube 4, so that the first water inlet hole 23 on the outer surface is aligned with one of the second water inlet holes 24 in the inner wall of the sampling tube 4, so that the lake water at the corresponding height will pass through the first filter screen 25, start the cleaning mechanism 26 and enter the sampling chamber at the corresponding height in the sampling tube 4, and then take the corresponding amount through the quantitative mechanism 27. Similarly, by controlling the rotation angle of the annular cover 21 and locking it through the driving mechanism 29, the sampling chambers at different heights in the sampling tube 4 can take lake water samples at different heights. In this way, a sampling tube 4 can be put into the lake to take out water samples at different heights at one time, thereby improving the collection efficiency, reducing the loss cost of manpower and equipment, and at the same time, reducing the impact of dynamic changes in environmental factors, ensuring the reliability and effectiveness of monitoring data. When the internal samples need to be stored and tested after taking the samples and lifting the sampling tube 4 out of the water, first align the bottom of the sampling tube 4 with the sample collection box, and then pull the card rod outward to drive the spring 285 to contract, so that one end of the sampling tube 4 moves out of the circular The water sample in the corresponding chamber will flow into the interior of the rotating rod 282 from the water outlet hole 283 and then be discharged through the second filter screen 288. At this time, the block 284 can be loosened and, under the reset action of the spring 285, it will be stuck in the card slot 286, limiting and fixing the rotating rod 282, so as to facilitate the discharge of the water sample in the corresponding sampling chamber. Similarly, the water samples in the other chambers are taken out in the same way, so as to achieve the purpose of separating and discharging water samples at different levels, which is convenient for later detection and processing.
