Description

Technical Field

[0001] This utility model relates to the field of water sampling technology, and in particular to an environmentally friendly water sampling device. Background Technology

[0002] Environmentally friendly water refers to wastewater or rainwater that has undergone appropriate treatment, meeting specific standards and suitable for reuse. Compared with seawater desalination and inter-basin water transfer, environmentally friendly water has significant advantages: it has the lowest treatment cost and can effectively improve the ecological environment and promote the sustainable use of water resources.

[0003] In the water treatment process, stratified sampling is a key means of analyzing the vertical distribution characteristics of water bodies. However, traditional fixed-depth samplers are difficult to adapt to the sampling needs at different depths, and are particularly inefficient in deep water areas or when sampling at multiple points.

[0004] In existing technologies, some adjustable depth sampling devices achieve precise sampling through complex structures such as electric valves and multi-stage linkages, as illustrated in the sampling device for environmental water treatment disclosed in CN221571953U. While such designs can meet the requirements for deep water sampling, their complex structure and high maintenance costs reduce their economic efficiency and practicality. It is particularly noteworthy that the depth of conventional water treatment ponds is generally around 3 meters; excessively advanced technology configurations could lead to functional redundancy.

[0005] Current complex sampling devices are more suitable for monitoring ultra-deep water bodies such as deep reservoirs and oceans, while the sampling needs of ordinary water treatment ponds have not yet been specifically addressed. This exposes a clear technical contradiction: existing solutions are either too simplistic to meet the requirements of stratified sampling, or over-designed, leading to escalating costs. This imbalance restricts the widespread adoption and efficiency of environmental water monitoring.

[0006] Based on the above problems, there is an urgent need to develop an environmentally friendly water sampling device. Utility Model Content

[0007] This utility model is an environmentally friendly water sampling device proposed to overcome the shortcomings of existing technologies.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: an environmentally friendly water sampling device, including a sleeve rod, a circular plate provided below the sleeve rod, a plurality of placement cylinders extending to the top of the circular plate being uniformly fixedly connected to the bottom of the circular plate, a sampling bottle being placed inside each of the plurality of placement cylinders, and a through hole being provided between two adjacent placement cylinders, and the through hole extending through the circular plate.

[0009] The top of the circular plate is fixedly connected to a long shaft, and the sleeve rod is rotatably sleeved on the outer surface of the long shaft. A graduated self-locking drive assembly is installed between the long shaft and the sleeve rod.

[0010] A manual lifting assembly is installed on one side of the outer surface of the sleeve rod, and a sealing plate is fixedly connected to the movable end of the manual lifting assembly.

[0011] Furthermore, a scale mark is provided on one side of the outer surface of the sleeve, which facilitates the insertion depth of the entire sleeve into the water.

[0012] Furthermore, the graduated self-locking drive assembly includes a handwheel, which is located on one side of the sleeve rod. A pointer is fixedly connected to the outer surface of the handwheel, and a worm is fixedly connected to one end of the handwheel. The worm passes through the sleeve rod and is rotatably connected to the sleeve rod. A worm wheel is meshed with the outer surface of the worm and is fixedly sleeved on the outer surface of the long shaft. The worm wheel and the worm have a self-locking function. When the worm does not rotate, the worm wheel cannot rotate under the action of external force.

[0013] Furthermore, a scale is fitted on the outer surface of the worm gear, and the scale is fixedly installed on one side of the outer wall of the sleeve and matches the pointer, which is beneficial for determining the angular displacement of the major axis.

[0014] Furthermore, the manual lifting assembly includes a knob, with a screw fixedly connected to the bottom of the knob. A movable sleeve is threaded onto the outer surface of the screw, and the movable sleeve is slidably fitted onto the outer surface of the sleeve rod. The knob facilitates manual driving of the screw rotation.

[0015] Furthermore, the outer surface of the screw is rotatably connected to a support seat, and the support seat is fixedly installed on one side of the outer wall of the sleeve rod. The support seat provides support for the screw and facilitates screw installation.

[0016] Furthermore, the sealing plate includes a pressure plate, which is fixedly installed at the bottom of the movable sleeve. An annular sealing gasket is fixedly connected to the bottom of the pressure plate. A through hole extending to the bottom of the annular sealing gasket is opened at the top of the pressure plate, and the through hole matches the through hole and the placement cylinder. This sealing structure ensures that only one sampling bottle is in the open state, completely avoiding cross-contamination of water samples at different depths.

[0017] The beneficial effects of this utility model are:

[0018] In use, this utility model provides an environmentally friendly water sampling device. Through the arrangement of a circular plate, a placement cylinder, a sampling bottle, a through hole, a long shaft, a graduated self-locking drive assembly, a manual lifting assembly, and a sealing plate, it can perform stratified sampling of water in water treatment tanks with a depth of less than 3 meters. It replaces the electric valves and multi-stage linkage structures of existing technologies with a purely mechanical structure, significantly reducing manufacturing costs and maintenance difficulties. It is especially suitable for sampling scenarios in conventional water treatment tanks, effectively solving the dual defects of inconvenient adjustment of traditional fixed samplers and poor economy of complex electric devices.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1 to 6 As shown, an environmentally friendly water sampling device is disclosed, including a sleeve rod 1. A scale mark 5 is provided on one side of the outer surface of the sleeve rod 1. The scale mark 5 is made of bright colors such as red, which facilitates observation.

[0030] A circular plate 17 is provided below the sleeve rod 1. Multiple placement cylinders 4 that extend to the top are evenly fixedly connected to the bottom of the circular plate 17. Each placement cylinder 4 contains a sampling bottle 16. A through hole 15 is provided between two adjacent placement cylinders 4, and the through hole 15 extends through the circular plate 17. The multiple placement cylinders 4 are arranged in a ring, and the multiple through holes 15 are also arranged in a ring. The spacing between the through hole 15 and the two adjacent placement cylinders 4 is consistent, which is conducive to subsequent adjustment.

[0031] A long shaft 8 is fixedly connected to the top of the circular plate 17, and a sleeve rod 1 is rotatably fitted onto the outer surface of the long shaft 8. A graduated self-locking drive assembly is installed between the long shaft 8 and the sleeve rod 1. The graduated self-locking drive assembly includes a handwheel 10, which is located on one side of the sleeve rod 1. A pointer 9 is fixedly connected to the outer surface of the handwheel 10, and a worm gear 19 is fixedly connected to one end of the handwheel 10. The worm gear 19 passes through the sleeve rod 1 and is rotatably connected to the sleeve rod 1. The rotatable connection structure is... Figure 6 As shown in the figure, an annular protrusion is provided on the outer surface of the worm 19, which is slidably embedded in the sleeve 1. A worm wheel 18 is meshed with the outer surface of the worm 19, and the worm wheel 18 is fixedly sleeved on the outer surface of the long shaft 8. A scale 11 is sleeved on the outer surface of the worm 19, and the scale 11 is fixedly installed on one side of the outer wall of the sleeve 1 and matches the pointer 9.

[0032] A manual lifting assembly is installed on one side of the outer surface of the sleeve rod 1. A sealing plate is fixedly connected to the movable end of the manual lifting assembly. The manual lifting assembly includes a knob 12. A screw 6 is fixedly connected to the bottom of the knob 12. A movable sleeve 2 is threadedly connected to the outer surface of the screw 6, and the movable sleeve 2 is slidably fitted onto the outer surface of the sleeve rod 1. A support seat 13 is rotatably connected to the outer surface of the screw 6, and the support seat 13 is fixedly installed on one side of the outer wall of the sleeve rod 1. The sealing plate includes a pressure plate 3, and the pressure plate 3 is fixedly installed at the bottom of the movable sleeve 2. An annular sealing gasket 7 is fixedly connected to the bottom of the pressure plate 3. A through hole 14 is opened at the top of the pressure plate 3, extending to the bottom of the annular sealing gasket 7. The through hole 14 matches the through hole 15 and the placement cylinder 4. The thread helix angle of the screw 6 is less than the friction angle. The screw 6 has a self-locking capability, which can prevent it from shifting due to vibration or load.

[0033] Working principle: First, place multiple sampling bottles 16 into the placement cylinder 4, then turn the knob 12. The knob 12 drives the screw 6 to rotate, the screw 6 drives the movable sleeve 2 to descend, the movable sleeve 2 drives the pressure plate 3 and the annular sealing gasket 7 to descend, until the annular sealing gasket 7 is sealed and adhered to the top of the circular plate 17 (depending on the operator's experience).

[0034] At this point, the through hole 14 corresponds to the lower through hole 15. Then, the entire unit is inserted into the water treatment tank. The approximate depth is determined by the scale mark 5. Then, the handwheel 10 is turned. The rotation angle of the handwheel 10 is determined by the pointer 9 and the dial 11. When the handwheel 10 rotates to a certain angle, it also drives the worm gear 18 to rotate to a certain angle through the worm 19. The worm gear 18 drives the circular plate 17 to rotate to a certain angle through the long shaft 8, so that the corresponding placement cylinder 4 is coaxial with the through hole 14. Water in the water treatment tank enters the placement cylinder 4 through the through hole 14 and then enters the sampling bottle 16. Since the bottle mouth of the sampling bottle 16 is facing upward, the water will enter quickly. After a period of time (depending on the operator's experience), the handwheel 10 is turned again, and the circular plate 17 is driven to a certain angle through the various components, so that the next through hole 15 is coaxial with the through hole 14. Then, the above operation is continued until the sampling is completed.

[0035] After sampling is complete, remove each sampling bottle 16.

[0036] In this application, all exposed component surfaces are treated with anti-corrosion measures to improve overall corrosion resistance and extend overall service life.
