Description

A portable groundwater sampling device

Technical Field

The utility model relates to the technical field of water quality sampling, in particular to a portable groundwater sampling device.

Background technique

Groundwater refers to water stored in the gaps in rocks below the ground. In a narrow sense, it refers to water in saturated aquifers below the groundwater surface. Groundwater refers to various forms of gravity water buried below the surface. Groundwater is an important component of water resources. Due to its stable water volume and good water quality, it is one of the important water sources for agricultural irrigation, industry, mining and cities. However, under certain conditions, changes in groundwater can also cause adverse natural phenomena such as swamping, salinization, landslides, and ground subsidence. At present, it is usually necessary to collect samples of groundwater for testing.

Existing equipment cannot accurately adjust the telescopic distance, which makes it inconvenient for the equipment to collect samples of groundwater at different depths, and easily leads to inaccurate collection of water quality samples by the equipment.

Detailed ways

The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

In one embodiment, as shown in Figures 1 to 3, the portable groundwater sampling device of the utility model includes a base 1, a gantry 2, a motor 3, a main shaft 4, a winch 5, a hose 6, a sampling container 7, a submersible pump 8, an encoder 10, an auxiliary shaft 11, an auxiliary wheel 13 and a sliding key 16. The gantry 2 is fixedly arranged on the base 1, the motor 3 is fixedly arranged in the gantry 2, the main shaft 4 is rotatably arranged in the gantry 2 and one end is fixedly arranged on the output end of the motor 3, the winch 5 is fixedly arranged on the main shaft 4, and the hose 6 is wound around the base 1. On the winch 5, the sampling container 7 is fixed on the gantry 2 and fixedly connected to the top of the hose 6, the submersible pump 8 is fixed at the bottom of the hose 6, the encoder 10 is fixed in the gantry 2, the auxiliary shaft 11 is rotatably arranged in the gantry 2 and one end is fixed on the detection end of the encoder 10, a long groove 12 is opened on the auxiliary shaft 11, an auxiliary wheel 13 is slidably arranged on the auxiliary shaft 11, a sliding key 16 is fixed in the auxiliary wheel 13 and slidably engaged in the long groove 12, and the auxiliary wheel 13 is fitted on the hose 6.

Among them, two sets of oppositely arranged electric telescopic rods 14 are fixedly provided inside the gantry 2, and balls 15 are clamped on the top of the electric telescopic rods 14. The two sets of balls 15 are rollingly fitted on both sides of the assisting wheel 13. A through slot 9 is provided on the base 1, and the bottom end of the hose 6 passes through the through slot 9 and is fixedly connected to the submersible pump 8. A display screen 17 is fixedly provided below the gantry 2, and the display screen 17 is electrically connected to the encoder 10. A plurality of sets of universal wheels 18 are fixedly provided at the bottom end of the base 1.

When in use, the motor 3 drives the main shaft 4 and the winch 5 to rotate, so that the hose 6 on the winch 5 is continuously released, and the submersible pump 8 at the bottom of the hose 6 can continuously increase the diving depth in the water. The submersible pump 8 pumps water and transports it to the sampling container 7 through the hose 6 to complete the water quality detection. In this process, the auxiliary wheel 13 is squeezed by the hose 6 and rotates continuously, so that the auxiliary shaft 11 is driven to rotate continuously through the cooperation of the sliding key 16 and the long groove 12. The encoder 10 at one end of the auxiliary shaft 11 can record the rotation angle and number of rotations of the auxiliary shaft 11, and feedback is given on the display screen 17, so that the user can intuitively obtain the depth change of the submersible pump 8. In the process of the hose 6 driving the auxiliary wheel 13 to rotate through friction, a group of electric telescopic rods 14 gradually extends, while the other group of electric telescopic rods 14 gradually shrinks, so that the auxiliary wheel 13 has a certain axial movement during the rotation process, and can maintain close contact with the hose 6 gradually released from the winch 5, maintaining the reliability of the sampling depth measurement.
