Description

Technical Field

[0001] This utility model relates to the technical field of point water sampling devices, specifically a point water sampling device for groundwater environment surveys. 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. Foreign scholars believe that there are three definitions of groundwater: First, all water buried underground that is significantly different from surface water, specifically the water in the saturated zone of an aquifer; second, water that flows downward or seeps in, saturating the soil and rocks and replenishing springs and wells; and third, water stored in underground rock cavities and in the gaps that make up the earth's crust. 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, mining, and cities.

[0003] Most existing groundwater environmental survey sampling devices require the equipment to rise and send the sampled groundwater out after sampling at one location, making it impossible to continuously sample groundwater at different depths and affecting the sampling efficiency of the equipment.

[0004] To address these issues, this invention provides a groundwater environmental survey and fixed-point water sampling device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a groundwater environmental survey fixed-point water sampling device, which solves the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a groundwater environment survey fixed-point water sampling device, comprising a base plate, a gantry frame fixedly connected to the top of the base plate, a fixed telescopic rod fixedly connected to the bottom of the gantry frame, a hydraulic rod fixedly connected to the top of the inner wall of the gantry frame, a protective chamber fixedly connected to the bottom of the hydraulic rod, a motor fixedly connected to the inner wall of the protective chamber, a water storage tank fixedly connected to the motor via its output end, a rotating ring rotatably connected to the inner wall of the water storage tank, a flexible hose connected to the side wall of the rotating ring, a water sampling pump connected to one end of the flexible hose, a water outlet pipe connected to the bottom of the water sampling pump, a telescopic pipe connected to the bottom of the water storage tank, a water sampling bucket fixedly connected to the bottom of the water storage tank, an electric push rod fixedly connected to the bottom of the water storage tank, a circular plate fixedly connected to the bottom of the electric push rod, a sealing element provided inside the circular plate, a water sampling hole opened on the side wall of the water sampling bucket, and a drill bit fixedly connected to the bottom of the water sampling bucket.

[0007] Preferably, a second electric slide rail is fixedly connected to the top of the base plate, and the test tube is slidably connected to the second electric slide rail via an electronic slider.

[0008] Preferably, the sealing element includes an electric rotating rod, the side wall of which is fixedly connected to the inner wall of the circular plate, and a rotating plate is fixedly connected to the side wall of the electric rotating rod.

[0009] Preferably, a position sensor is fixedly connected to the top of the drill bit, and a display is fixedly connected to the side wall of the base plate.

[0010] Preferably, the inner wall of the water collection hole is fixedly connected to a barrier net, and the side wall of the circular plate is slidably connected to the inner wall of the water collection bucket.

[0011] Preferably, the water collection bucket has an electric slide rail fixedly connected to its side wall, and the electric slide rail is slidably connected to a sealing plate via an electronic slider.

[0012] This utility model provides a fixed-point water sampling device for groundwater environmental surveys. Compared with the prior art, it has the following advantages:

[0013] (1) The groundwater environmental survey fixed-point water sampling device is used by the staff to place the base plate at the location where water needs to be sampled, start the fixed telescopic rod to fix the base plate on the ground to prevent the equipment from tipping over when drilling water. Start the motor, and the motor drives the drill bit to rotate to drill the ground through the water storage tank and the water sampling bucket. Start the hydraulic rod, and the hydraulic rod drives the drill bit to press down through the protective chamber, motor, water storage tank and water sampling bucket until the water sampling bucket moves to the location where water needs to be sampled. Start the electric push rod, and the electric push rod drives the circular plate to rise and retract. The water sampling bucket draws external water into the water sampling bucket through the water sampling hole through the negative pressure. Start the electric rotating rod, and the electric rotating rod drives the rotating plate to rotate so that the telescopic pipe is connected to the inside of the water sampling bucket. Start the water sampling pump, and the water sampling pump draws the water source sampled inside the water sampling bucket through the hose, rotating ring, water storage tank and telescopic pipe. The equipment can rise after water sampling and continue to sample groundwater at different locations to improve the water sampling efficiency of the equipment.

[0014] (2) In this groundwater environmental survey fixed-point water sampling device, after the water sampling pump has finished sampling the groundwater, the second electric slide rail drives a test tube to move to the bottom of the outlet pipe. The water sampling pump injects the sampled groundwater into the test tube for storage through the outlet pipe. By setting up multiple test tubes, groundwater at different locations can be stored.
