Description

Technical Field

[0001] The present invention relates to the technical field related to groundwater detection, and in particular to a groundwater detection sampling device. Background Art

[0002] A groundwater sampling device is a tool specifically used to extract groundwater samples. It is widely used in groundwater environmental monitoring, groundwater resource development and utilization, environmental pollution investigation, and hydrological research. Different types of groundwater sampling devices have different working principles. For example, a sampling cylinder sampler collects liquid samples through a closed cylinder; an inertial sampler uses the principle of inertia for sampling; and a gas-driven sampler drives the sampling mechanism through the pressure difference of the gas to collect liquid samples.

[0003] The publication number CN209102458U discloses a groundwater survey sampling device, including a mounting plate, a mounting frame and a servo motor are provided on the surface of the mounting plate, a conveying disc is rotatably connected in the mounting frame, and three sections of survey rods are sleeved in the conveying disc and connected to the conveying disc by threads. The device is composed of a survey bottom rod, a survey middle rod and a survey top rod, which is not only convenient for transportation operations, but also allows users to combine and install the overall length according to the needs of use, which is convenient for surveying. At the same time, when the water sensing switch contacts the groundwater, the indicator light works, so that the user can measure the depth of the groundwater according to the depth of the survey rod into the ground, and at the same time, the external pipeline is connected to the connecting pipe inside the survey top rod, and then the external water pump is connected to extract the groundwater, which is convenient for the user to perform groundwater sampling operations.

[0004] Currently, commonly used groundwater sampling devices include borehole samplers, tube samplers, etc. These devices are generally complex in structure and cumbersome to install. Moreover, after installation, these devices can usually only sample groundwater at one depth. If you want to sample groundwater at different depths, you need to re-lower the device and re-fix it, which is inconvenient to use. At the same time, during the sampling process, the water body needs to be simply filtered to prevent large particles of impurities from entering. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a groundwater detection sampling device to solve the problems existing in the above-mentioned background technology.

[0006] The present invention provides the following technical solutions: a groundwater detection sampling device, comprising a submersible body, the submersible body comprising a device shell, the interior of the device shell is fixedly connected with a connecting bottom plate, the top of the connecting bottom plate is rotatably connected with a limiting plate, the limiting plate is provided with a mounting groove, a sampling bottle is movably connected to the mounting groove, a support tube is fixedly connected to the center of the connecting bottom plate, the top of the support tube is fixedly connected with a connecting bin, the bottom of the connecting bin is rotatably connected with a connecting plate, a sampling bin is arranged on the submersible body, the sampling bin comprises a fixing ring, a supporting ring is fixedly connected between two fixing rings, a connecting side plate is fixedly connected to the side of the supporting ring, a cleaning brush is fixedly connected to the inner side of the connecting side plate, a sampler is rotatably connected to the inner side of the cleaning brush, a filtering device and a fixing device are fixedly connected to the inner side of the sampler;

[0007] During use, groundwater is sampled through the sampling chamber on the submersible body, and the groundwater sample is preliminarily filtered through the filtering device to filter out larger particles or aquatic plants in the water. The particles or aquatic plants blocked on the outer side of the filtering device will be cleaned by the cleaning brush on the connecting side panel when the filtering device rotates. At the same time, after reaching the sampling depth, sampling is carried out through the sampling chamber, and the water sample enters the sampling bottle through the support tube, the connecting chamber and the sampling nozzle. After the sampling is completed, the motor drives the limit plate to rotate, so that the sampling bottle is replaced and sampling at the next depth can be carried out.

[0008] During use, when sampling is performed through the sampling chamber, the sampling chamber sucks the water sample into the connecting pipe through the sampling device, and then reaches the connecting chamber through the supporting tube, and injects the water sample into the sampling bottle through the sampling nozzle at the bottom of the connecting chamber. After the collection of a single sampling bottle is completed, the sampling bottle is replaced by rotating the limit plate to continue collecting, thereby achieving multiple sampling. During use, the sampling efficiency can be improved, and the accuracy of water body monitoring can also be improved.

[0009] During use, when water is absorbed through the sampling device, aquatic plants and stones inside the water body may enter it, thereby causing blockage in the pipes inside the device. The filtering device can block aquatic plants, stones and other debris outside, but at the same time, the aquatic plants may also be stuck on the filtering device. The filtering device will rotate during sampling, and a connecting side plate is provided on the side of the filtering device. A cleaning brush is fixedly connected to the inner side of the connecting side plate. When the filtering device rotates, the cleaning brush is stationary. The relative rotation of the filtering device and the cleaning brush will cause the cleaning brush to clean the debris on the surface of the filtering device, thereby preventing the entry of debris and improving the sampling efficiency.

[0010] Furthermore, the cleaning brush is provided with evenly distributed nylon bristles, which are soft, wear-resistant, and corrosion-resistant and will not cause scratches or damage to the surface of the device.

[0011] Furthermore, a sampling nozzle is fixedly connected to the bottom of the connecting bin, a plurality of limiting grooves are provided inside the connecting plate, and an opening groove is provided on the side of one of the limiting grooves on the connecting plate.

[0012] Furthermore, a cover plate is rotatably connected to the opening groove of the connecting plate, and a cover plate handle is fixedly connected to the cover plate. The sampling nozzle, the connecting chamber and the interior of the support tube are communicated with each other, and a motor is arranged inside the connecting chamber. The connecting plate is driven by the motor to rotate so that the position where the opening groove is provided on the connecting plate rotates to the cover plate. The cover plate handle is held to drive the cover plate to rotate outward on the connecting plate, so that the sampling bottle placed between the limit plate and the connecting plate can be taken out or the sampling bottle can be placed between the limit plate and the connecting plate.

[0013] Furthermore, a sampling door panel is movably connected to the outer shell of the device to facilitate the placement and removal of sampling bottles, and a drill bit is fixedly connected to the bottom of the submersible body.

[0014] Furthermore, frozen blue ice is placed inside the limiting plate and the connecting plate to facilitate the preservation of the collected groundwater samples.

[0015] Furthermore, a movable plate is fixedly connected to the bottom of the filtering device, and the filtering device is divided into two layers. The filtering device of the first layer is a long strip structure, and the filtering device of the second layer is a ring structure with a plurality of filtering holes provided thereon for preliminary filtering of the sample during sampling to prevent rocks, aquatic plants, etc. from entering the sampling chamber and causing blockage of the sampling chamber.

[0016] Furthermore, a sampling device is fixedly connected inside the filtering device, a connecting pipe is fixedly connected to the top of the sampling device, and the top of the connecting pipe is fixedly connected to the fixing device. After passing through the filtering device, the groundwater enters the connecting pipe through the water pump inside the sampling device, and then enters the supporting pipe through the connecting pipe.

[0017] Beneficial effects:

[0018] 1. The groundwater detection sampling device, during the use of the device, the sampling operation is performed through the sampling chamber. After the collection of a single sampling bottle is completed, the sampling bottle is replaced by rotating the limit plate to continue collecting, thereby realizing multiple sampling. When in use, it can improve the sampling work efficiency and also improve the accuracy of water body monitoring.

[0019] 2. In the groundwater detection sampling device, the filter device will rotate during sampling. A cleaning brush is provided on the side of the filter device. The relative rotation of the filter device and the cleaning brush will enable the cleaning brush to clean the debris on the surface of the filter device, thereby preventing the entry of debris and improving the sampling efficiency.

[0029] During use, groundwater is sampled through the sampling chamber 3 on the submersible body 1, and the groundwater sample is preliminarily filtered through the filter device 307 to filter out larger particles or aquatic plants in the water.
