Description

Technical Field

[0001] This utility model belongs to the field of water environment monitoring technology, and specifically relates to a sampling device for water environment monitoring. Background Technology

[0002] In the field of water environment monitoring, obtaining highly representative samples that can accurately reflect water quality at different depths and over time is a key prerequisite for accurate analysis.

[0003] However, traditional sampling devices have relatively simple functions and generally have obvious limitations: on the one hand, most fixed or simple sedimentation samplers are difficult to control the sampling depth precisely, making the samples susceptible to interference from surface water or mixed water layers, and unable to truly represent the chemical and biological state of a specific water layer, which seriously restricts the ability to conduct vertical profile analysis of water bodies and trace hidden pollution sources; on the other hand, their sampling process is mostly discrete single operation, which is inefficient, and there is a long operation window when changing sample containers, which makes it easy to miss key data of sudden and intermittent pollution events, making it difficult to meet the requirements of modern environmental monitoring for the integrity and efficiency of time-series data.

[0004] Therefore, a sampling device for water environment monitoring is proposed to solve the problems mentioned above. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model proposes a sampling device for water environment monitoring.

[0008] Preferably, a first motor is fixed on the support platform, and a drive rod is fixedly installed on the shaft end of the first motor. The drive rod is L-shaped, and a limit plate is fixedly installed on the top end of the drive rod.

[0009] Preferably, the limiting groove is an arc-shaped groove, the driving groove is a strip-shaped groove, and there are four limiting grooves and four driving grooves, which are alternately distributed along the circumference of the receiving block.

[0017] To enable those skilled in the art to better understand this utility model, it will now be further described in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of this utility model.

[0018] Example 1: like Figures 1-5 As shown, this utility model provides a sampling device for water environment monitoring. The sampling device includes a platform 1 with an alternating mechanism. This mechanism drives the sampling cylinder 31 to move alternately, thereby improving sampling efficiency. A lifting mechanism is located at the bottom of the platform 1 to adjust the sampling depth and facilitate sample collection. A water pump 6 is fixed on the platform 1 for drawing water samples. The inlet pipe of the water pump 6 passes through the platform 1 and has a telescopic pipe 4. The telescopic pipe 4 facilitates the raising and lowering of the inlet head 8. An inlet head 8 with a solenoid valve is located at the bottom of the telescopic pipe 4. The alternating mechanism... The system includes a shaft 39, which is rotatably connected to a support 1. The shaft 39 is used for the installation of a receiving block 38 and a turntable 32. The receiving block 38 is fixedly installed on the shaft 39. The receiving block 38 has a limiting groove 36 and a driving groove 37. The limiting groove 36 is used to receive the insertion of a limiting plate 35, and the driving groove 37 is used to receive the insertion of a driving rod 34. The top of the shaft 39 is fixedly installed on the turntable 32. The turntable 32 is used to receive the installation of a positioning sleeve 310. The positioning sleeve 310 is fixed on the turntable 32. The positioning sleeve 310 is used to receive the insertion of a sampling cylinder 31. The sampling cylinder 31 is inserted into the positioning sleeve 310 and is used to store samples. The lifting mechanism includes a slide rod 21, which is fixedly installed at the bottom of the support platform 1. The slide rod 21 serves to limit the movement of the lifting rod 22. The lifting rod 22 is slidably mounted on the slide rod 21. The lifting rod 22 is used to support the installation of the connecting rod 210. The connecting rod 210 is fixedly installed at one end of the lifting rod 22. The connecting rod 210 is used to drive the water inlet head 8 and the scale 24 to move vertically. The water inlet head 8 is installed on the connecting rod 210. The scale 24 is fixedly installed on the connecting rod 210. The scale 24 is used to facilitate the observation of the sampling depth. The top of the scale 24 penetrates through the top of the support platform 1.

[0019] Several inserts 5 are fixedly installed at the bottom of the support platform 1. The inserts 5 are used to support the support platform 1 on the water surface. The inserts 5 are vertically arranged. A bracket 7 is fixed on the support platform 1. A water outlet 9 is fixed on the inner wall of the bracket 7. The water outlet pipe of the water pump 6 is connected to the water outlet 9. The water outlet 9 is arranged in conjunction with the water pump 6 to facilitate the delivery of sample water into the sampling tube 31.

[0020] A first motor 33 is fixed on the support platform 1. The first motor 33 is used to drive the drive rod 34 to rotate. The drive rod 34 is fixedly installed on the shaft end of the first motor 33. The drive rod 34 is L-shaped and is used to be inserted into the drive groove 37. A limit plate 35 is fixedly installed on the top of the drive rod 34. The limit plate 35, together with the limit groove 36, plays the role of limiting the movement of the receiving block 38.

[0021] The limiting groove 36 is an arc-shaped groove, and the driving groove 37 is a strip-shaped groove. There are four limiting grooves 36 and four driving grooves 37. The limiting grooves 36 and the driving grooves 37 are alternately distributed around the circumference of the receiving block 38. The limiting groove 36 is set to receive the insertion of the limiting plate 35.

[0022] A mounting plate 26 is fixed to the bottom of the platform 1. A drive wheel 29 and a driven wheel 23 are rotatably connected to the mounting plate 26. The drive wheel 29 and the driven wheel 23 are used to drive the track 25 for transmission.

[0023] A track 25 is meshed with the drive wheel 29 and the driven wheel 23. The track 25 is used to drive the drive block 27 to move. The drive block 27 is fixedly installed on the track 25. The drive block 27 is cylindrical. The drive block 27 is configured to cooperate with the through groove 211 to drive the lifting rod 22 to slide linearly along the surface of the slide rod 21. The lifting rod 22 has a through groove 211, and the drive block 27 slides on the inner wall of the through groove 211.

[0024] A second motor 28 is fixedly mounted on the mounting plate 26. The second motor 28 is horizontally positioned, and the shaft end of the second motor 28 passes through the mounting plate 26 and is fixedly connected to the drive wheel 29. The second motor 28 is positioned to drive the drive wheel 29 to rotate.

[0025] When water sampling is required, the second motor 28 is started first, according to the required sampling depth. The second motor 28 drives the drive wheel 29 to rotate. When the drive wheel 29 rotates, it works with the driven wheel 23 to drive the track 25 for transmission. When the track 25 is in transmission, it drives the drive block 27 to move. When the drive block 27 moves, it drives the lifting rod 22 to slide vertically along the surface of the slide rod 21 through the through groove 211. When the lifting rod 22 moves vertically, it drives the water inlet head 8 and the scale 24 to move vertically through the connecting rod 210 until the water inlet head 8 moves to the appropriate depth.

[0026] Then, the solenoid valve at the inlet head 8 is opened by the controller, and the water pump 6 is started. The water pump 6 will draw sample water through the telescopic pipe 4 and the inlet head 8. The sample water will enter the outlet head 9 through the water pump 6 and fall into the sampling cylinder 31 through the outlet head 9.

[0027] When it is necessary to replace the sampling cylinder 31, the water pump 6 can be turned off and the first motor 33 can be started. The first motor 33 drives the drive rod 34 and the limit plate 35 to rotate. The initial state of the drive rod 34 and the limit plate 35 is shown in the attached figure. Figure 2 As shown, the limiting disk 35 is located in one of the limiting grooves 36. As the limiting disk 35 and the drive rod 34 rotate, when the drive rod 34 is inserted into the drive groove 37, the limiting disk 35 has disengaged from the limiting groove 36. As the drive rod 34 and the limiting disk 35 rotate, the drive rod 34 will drive the receiving block 38 to rotate through the drive groove 37 until the drive rod 34 leaves the drive groove 37. At this time, the limiting disk 35 moves back into the limiting groove 36, thereby fixing the receiving block 38. Through the above settings, the receiving block 38 will perform a quarter-intermittent circular motion. During the movement, the receiving block 38 will drive the turntable 32 to rotate a quarter-intermittently through the shaft 39, thereby accurately moving the next sampling cylinder 31 directly below the water outlet 9, so that the water outlet 9 can put the sample into the next sampling cylinder 31.

[0028] The above are merely preferred embodiments of the present utility model and do not limit the patent scope of the present utility model. All equivalent changes and modifications made within the scope of the present utility model shall still fall within the scope of the present utility model.
