Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to an energy-saving sampling device for water ecological management. Background Art

[0002] Water pollution control is a very important part of environmental governance. Water pollution control not only needs to restore water quality, but also the ecological environment in the water. Water quality monitoring is an important part of water ecological governance. Water quality monitoring requires regular sampling, analysis, and monitoring of water bodies in different areas, depths, and at different times. Water sampling refers to the collection of water samples from polluted water bodies, and through analysis and measurement, to obtain basic data on water pollution. Water samples for analysis should be representative and reflect the chemical composition and characteristics of the water body. The sampling method, location, time, and number of times are all determined according to the characteristics of the water body and the purpose of analysis.

[0003] Since the amount of sampling is large, it is a lot of physical labor for the staff, so some automatic samplers have appeared. However, although the automatic sampler is convenient for sampling, its overall use is also cumbersome, and the overall weight is heavy, which is inconvenient to carry. In addition, many existing sampling devices do not consider the cleaning of the sampling tube to avoid the mutual influence between samples. Therefore, a more efficient, energy-saving, easy-to-use and portable water sampling device can be designed. Utility Model Content

[0004] The purpose of the utility model is to provide an energy-saving sampling device for water ecological management, which can efficiently sample water without using energy-consuming equipment, and can conveniently clean the sampling device to reduce the impact between water bodies.

[0006] Furthermore, the second through hole is opened at an end of the partition away from the first through hole.

[0007] Furthermore, a circular fixing block is fixedly provided on the outer wall of the piston cylinder, a collar is sleeved on the outer wall of the fixing block, the collar is connected to a connecting rod, and the connecting rod is connected to the water absorption rod; the collar is rotatably connected to the fixing block.

[0008] Furthermore, one end of the connecting rod away from the sleeve ring is connected to a horizontally arranged limit ring, the inner wall of the limit ring is provided with a spherical groove, and a limit ball is rotatably arranged in the groove; the water absorption rod is connected to the limit ball.

[0009] Furthermore, a counterweight ball is provided at the lower end of the water absorption rod.

[0010] Furthermore, the outer wall of the water absorption rod is provided with a scale bar along the length direction.

[0011] Furthermore, an indicator block is sleeved on the outer wall of the water absorption rod, and the indicator block is slidably connected to the water absorption rod.

At this time, the piston plate can be moved away from the partition by pulling the push rod, thereby generating negative pressure in the first chamber and the second chamber. The negative pressure acts on the water suction rod through the water pipe, and the water in the water body is sucked into the sampling tube through the water suction rod and the water pipe through the water suction hole at the lower end of the water suction rod. After sampling, the sampling tube can be removed. When it is necessary to sample a new water body, pure water can be added to the sampling tube first, and then the tube can be screwed into the connecting tube.

[0023] Example

[0024] The following is further described in conjunction with specific embodiments. Figure 1 -Attached Figure 2As shown, the energy-saving sampling device for water ecological management of this embodiment includes a piston cylinder 11 arranged horizontally and sealed at one end, a first through hole 13 arranged on the side wall of the piston cylinder 11, a connecting cylinder 14 arranged at the first through hole 13 on the outer wall of the piston cylinder 11, a sampling tube 15 detachably connected to the connecting cylinder 14, a partition 12 fixedly arranged in the piston cylinder 11, a second through hole 16 opened in the partition 12, a piston plate 19 slidably arranged in the piston cylinder 11, a push rod 110 connected to the piston plate 19, and a push rod 110 connected to the outer wall of the piston cylinder 11. A hollow water suction rod 22, a water suction hole 29 opened at the lower end of the water suction rod 22, and a water pipe 21 inserted into the piston cylinder 11; the partition 12 divides the piston cylinder 11 into a first chamber 17 close to the sealed end of the piston cylinder 11, and a second chamber 18 close to the open end of the piston cylinder 11; the first through hole 13 is opened in the side wall of the first chamber 17, one end of the water pipe 21 is connected to the water suction rod 22, and the other end is arranged in the first chamber 17 and passes through the connecting tube 14, and the piston plate 19 and the push rod 110 are arranged in the second chamber 18. Specifically, when in use, first screw the sampling tube 15 into the connecting tube 14 (fixed by threaded connection), and then extend the water absorption rod 22 into the water body. At this time, the piston plate 19 can be moved away from the partition 12 by pulling the push rod 110, thereby generating negative pressure in the first chamber 17 and the second chamber 18. The negative pressure acts on the water absorption rod 22 through the water pipe 21, and the water in the water body is sucked into the sampling tube 15 through the water absorption rod 22 and the water pipe 21 through the water absorption hole 29 at the lower end of the water absorption rod 22. After sampling, the sampling tube 15 can be removed. When it is necessary to sample a new water body, pure water can be added to the sampling tube 15 first, and then it can be screwed into the connecting tube 14. At this time, the piston plate 19 can be pushed by pushing the push rod 110 to move, thereby generating a positive pressure in the first chamber 17. The positive pressure will press the water in the sampling tube 15 into the water pipe 21 and the water suction rod 22 (the water pipe 21 is inserted into the water in the sampling tube 15), thereby achieving the effect of cleaning the water pipe 21 and the water suction rod 22. Therefore, this device can not only efficiently sample the water body, but also has a simple structure, no additional electrical structure, and is more efficient and energy-saving to use. It can also reduce the mutual influence of different water qualities through self-cleaning. It should be noted that the piston tube can be set in a fixed position, and then the electric structure is used to drive the piston plate 19 to move, so that it is convenient to automatically and regularly sample.

[0025] In this embodiment, the second through hole 16 is formed at an end of the partition plate 12 away from the first through hole 13. Specifically, this can prevent water from entering the second chamber 18 through the second through hole 16.

[0026] In this embodiment, a circular fixing block 23 is fixedly provided on the outer wall of the piston cylinder 11, and a collar 24 is sleeved on the outer wall of the fixing block 23. The collar 24 is connected to a connecting rod 25, and the connecting rod 25 is connected to the water absorption rod 22; the collar 24 is rotatably connected to the fixing block 23. The end of the connecting rod 25 away from the collar 24 is connected to a horizontally arranged limiting ring 26, and a spherical groove is provided on the inner wall of the limiting ring 26, and a limiting ball 27 is rotatably arranged in the groove; the water absorption rod 22 is connected to the limiting ball 27. Specifically, when the piston cylinder 11 is operated by hand, through the cooperation of the sleeve and the fixing block 23, and the rotation of the limiting ball 27 in the limiting ring 26, the water absorption rod 22 can still remain vertical under the premise that the piston cylinder 11 does not remain horizontal and is constantly shaking.

[0027] The lower end of the water absorption rod 22 in this embodiment is provided with a weight ball 28. Specifically, the weight ball 28 is used to keep the water absorption rod 22 in a vertical state.

[0028] In this embodiment, the outer wall of the water absorbing rod 22 is provided with scale bars along the length direction. The outer wall of the water absorbing rod 22 is provided with an indicator block 210, and the indicator block 210 is slidably connected to the water absorbing rod 22. By moving the indicator block 210 to the corresponding scale, and then absorbing water to bring the indicator block 210 close to the water surface, the sample in the water body at a specified depth can be easily absorbed.

[0029] In this embodiment, a sliding rod 111 is provided on one side of the partition plate 12 close to the piston plate 19, and a sliding hole 112 is provided on both the piston plate 19 and the push rod 110; the sliding rod 111 is slidably arranged in the sliding hole 112. Specifically, this can ensure that the push rod 110 and the piston plate 19 can stably move along a straight line.

[0030] In summary, when using the energy-saving sampling device for water ecological management of this embodiment, the sampling tube 15 is first screwed into the connecting tube 14 (fixed by threaded connection), and then the water suction rod 22 is extended into the water body. At this time, the piston plate 19 can be moved away from the partition 12 by pulling the push rod 110, thereby generating negative pressure in the first chamber 17 and the second chamber 18. The negative pressure acts on the water suction rod 22 through the water pipe 21, and the water in the water body is sucked into the sampling tube 15 through the water suction rod 22 and the water pipe 21 through the water suction hole 29 at the lower end of the water suction rod 22. After sampling, the sampling tube 15 can be removed. When it is necessary to sample a new water body, pure water can be added to the sampling tube 15 first, and then it can be screwed into the connecting tube 14. At this time, the piston plate 19 can be pushed by pushing the push rod 110 to move, thereby generating a positive pressure in the first chamber 17. The positive pressure will press the water in the sampling tube 15 into the water pipe 21 and the water suction rod 22, thereby achieving the effect of cleaning the water pipe 21 and the water suction rod 22. Therefore, the device can not only efficiently sample water bodies, but also has a simple structure, no additional electrical structure, is more efficient and energy-saving, and can also reduce the mutual influence of different water qualities through self-cleaning.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
