Description

Technical Field

[0001] This utility model relates to the field of water quality sampling techniques, and in particular to a portable groundwater sampling device. Background Technology

[0002] Groundwater refers to water that exists in the pores of rocks below the ground surface. In a narrow sense, it refers to water in saturated aquifers below the groundwater level. Groundwater refers to various forms of gravity water buried below the earth's surface. Groundwater is an important component of water resources. Due to its stable quantity and good quality, it is one of the important water sources for agricultural irrigation, industry and mining, and cities. However, under certain conditions, changes in groundwater can also cause adverse natural phenomena such as marshland formation, salinization, landslides, and ground subsidence. Currently, groundwater testing usually requires the collection of samples.

[0003] Currently, when sampling groundwater, staff manually use a water sampling bucket to collect samples. This requires manually pulling the bucket with a rope, which causes the bucket to shake during the pulling process, resulting in less water being collected and potentially affecting subsequent use. Utility Model Content

[0004] The purpose of this invention is to provide a portable groundwater sampling device to solve the problem of water loss due to shaking when workers pull the water bucket with a rope to collect samples.

[0005] To achieve the above objectives, a portable groundwater sampling device is provided, comprising: a base, a box being provided at the upper end of the base, two vertical plates being symmetrically fixedly connected to the inner wall of the box, a receiving roller being rotatably connected between the two vertical plates, a flexible tube being wound around the outside of the receiving roller, a second gear being rotatably connected inside the vertical plates, a limiting plate being slidably connected inside the vertical plates, and a first gear being provided on the lower surface of the limiting plate;

[0006] The base has two slide rods fixedly connected at intervals on its inner wall. A movable plate is slidably connected inside the base. Two sliders are slidably connected outside the slide rods. Connectors are provided on the lower surface of the sliders and the upper surface of the movable plate. Push rods are provided at intersections on the side walls of the connectors. Rollers are provided on the lower surface of the movable plate.

[0007] According to the portable groundwater sampling device, a second spring is provided at both ends of the slide rod, a limiting block is fixedly connected to the upper surface of the slider, two mounting plates slide on the inner wall of the base, and a positioning rod is fixedly connected to the side wall of each of the two mounting plates. The front end of the positioning rod extends to the outside through the middle of the limiting block.

[0008] According to the portable groundwater sampling device, a plurality of third springs are spaced apart between the two mounting plates, and a toggle plate is fixedly connected to the side wall of the mounting plate, with one end of the toggle plate extending through the side wall of the base to the outside.

[0009] According to the portable groundwater sampling device, a pull rod is fixedly connected to the upper end of the limiting plate, the outside of the pull rod is slidably connected to the middle of the box, a connecting rod is fixedly connected between the two pull rods, and the side wall of the second gear is fixedly connected to one end of the receiving roller.

[0010] According to the portable groundwater sampling device, a water tank is installed inside the box, a water pump is installed at the bottom of the water tank, one end of the water pump is connected to one end of a hose, and a box door is installed on the outside of the box.

[0011] According to the portable groundwater sampling device, a handle is fixedly connected to the upper end of the box, a channel is opened on the side wall of the box, and two support frames are fixedly connected at intervals on the side wall of the box, with a support roller rotatably connected between the two support frames.

[0013] The above-mentioned solution has the following beneficial effects:

[0014] 1. This utility model involves wrapping a flexible hose around the outside of a receiving roller and rotating the receiving roller using a rocker arm. With the help of a support roller, the length of the hose can be adjusted. A submersible pump is installed at the front end of the hose. By using the submersible pump in conjunction with a water pump, groundwater can be sampled, which is more efficient than manual sampling by workers in the prior art.

[0027] The inner wall of the base 1 has two fixedly connected sliding rods 23 at intervals. A movable plate 26 is slidably connected inside the base 1. Two sliders 24 are slidably connected to the outside of the sliding rods 23. Connectors 27 are provided on the lower surface of the sliders 24 and the upper surface of the movable plate 26. The upper surface of the movable plate 26 is connected to the connectors 27 and slides inside the movable plate 26. Push rods 25 are cross-arranged on the side wall of the connectors 27. The two ends of the push rods 25 are rotatably connected to the side wall of the connectors 27. Rollers 21 are provided on the lower surface of the movable plate 26 to facilitate movement of the heavy box 2 after groundwater collection.

[0028] Both ends of the slide bar 23 are equipped with second springs 20. The elasticity of the second springs 20 can push the slider 24 to move, facilitating the adjustment of the height of the roller 21. A limit block 22 is fixedly connected to the upper surface of the slider 24. Two mounting plates 29 slide on the inner wall of the base 1. Positioning rods 28 are fixedly connected to the side walls of the two mounting plates 29, which can position the roller 21. The front end of the positioning rod 28 extends to the outside through the middle of the limit block 22. Multiple third springs 30 are arranged at intervals between the two mounting plates 29 to facilitate the movement of the mounting plates 29. A toggle plate 7 is fixedly connected to the side wall of the mounting plate 29. One end of the toggle plate 7 extends to the outside through the side wall of the base 1. The upper end of the limit plate 17 is fixedly connected to... A pull rod 9 is attached, and the outside of the pull rod 9 is slidably connected to the middle of the box body 2. A connecting rod 10 is fixedly connected between the two pull rods 9. The side wall of the second gear 19 is fixedly connected to one end of the storage roller 13. A water tank 15 is set inside the box body 2. A water pump 14 is set at the bottom of the water tank 15. One end of the water pump 14 is connected to one end of the hose. A box door 8 is set on the outside of the box body 2. A handle 11 is fixedly connected to the upper end of the box body 2. A channel 3 is opened on the side wall of the box body 2. Two support frames 5 are fixedly connected at intervals on the side wall of the box body 2. A support roller 4 is rotatably connected between the two support frames 5.

A first spring 16 is set on the upper surface of the limiting plate 17.

[0029] Working principle: When in use, the box 2 is relatively light when no groundwater is sampled, and the staff can carry the box 2 by hand. After groundwater sampling, the box 2 becomes heavier. Therefore, the second spring 20 pushes the slider 24 to move, and with the cooperation of the connecting piece 27 and the push rod 25, it pushes the movable plate 26 to move, so that the roller 21 contacts the bottom surface. The staff pushes the box 2 to move. After the roller 21 contacts the bottom surface, the third spring 30 elastically pushes the mounting plate 29 to move, so that the positioning rod 28 passes through the middle of the limiting block 22, thereby positioning the movable plate 26.

[0030] Workers pull the lever 9 using the connecting rod 10 and manually rotate the rocker arm 6. With the help of the support roller 4, the external hose of the receiving roller 13 is released, allowing the submersible pump to fall into the groundwater. The submersible pump is placed at different depths as needed for collection. With the help of the water pump 14, the groundwater is collected into the water tank 15. After collection, the submersible pump and hose are collected in the opposite direction. The water does not spill during the collection process.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
