Description

Technical Field

[0001] The utility model relates to the technical field of water resource detection, and more specifically to a groundwater resource extraction and detection device. Background Art

[0002] In the field of groundwater resource exploration and research, accurate extraction and testing of groundwater samples is extremely important for understanding the quality, composition and availability of groundwater resources. Traditional groundwater resource extraction and testing often rely on relatively scattered equipment combinations and complex operating procedures.

[0003] Some existing groundwater extraction devices usually use a simple rope hanging bucket or simple sampling bottle to collect water samples. This method has many disadvantages when facing a complex underground environment. For example, there is a lack of effective filtering mechanism in the process of extracting water samples. Water samples are collected only by relying on the simple opening of the bucket or sampling bottle, resulting in a large amount of sediment, suspended impurities and other pollutants in the collected water samples, which seriously affects the accuracy of subsequent water quality testing and makes it difficult for the test results to truly reflect the actual situation of groundwater resources. Moreover, this traditional extraction method is inconvenient to operate and requires manual lowering and lifting of sampling tools. It is not only labor-intensive and inefficient, but also difficult to accurately control the sampling position and depth in some groundwater sources with large depths or harsh environments (such as narrow spaces, turbulent water flow, etc.), and cannot meet the diverse needs of groundwater resource extraction. In addition, traditional equipment lacks an overall design of portability, and the various components are scattered, which is not convenient to carry to remote testing locations, limiting the timely and effective detection of widely distributed groundwater resources.

[0004] Therefore, a groundwater resource extraction and detection device is proposed. Utility Model Content

[0016] Preferably, the filter aperture of the filter assembly ranges from 0.1 mm to 1 mm, wherein the filter apertures of the filter sleeve, the medium-sized filter screen cartridge, and the small-sized filter screen cartridge decrease gradually from the outside to the inside.

[0017] The water quality analyzer is arranged inside the upper shell of the box shell and is connected to the extraction bottle through a pipeline, and is used for analyzing and detecting the extracted and filtered water samples.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] 1. Strong portability: This device adopts a portable box design, integrating the water quality analyzer, winding mechanism and water extraction mechanism, which is convenient to carry to different groundwater resource detection locations. Whether it is field survey or in some remote and inconvenient areas, it can be easily transported and operated, which greatly improves the flexibility and convenience of detection and overcomes the limitations of traditional large-scale detection equipment that is difficult to move and deploy.

[0020] 2. Good filtering effect: The unique filter component design consists of a filter sleeve, a medium-sized filter screen cylinder and a small filter screen cylinder, and the diameter of the outer holes of the three gradually decreases from the outside to the inside, which can filter the impurities in the groundwater layer by layer.

In shallow waters or areas with slow water flow, the number of counterweight rings can be reduced to achieve rapid sinking; in deep waters or areas with turbulent water flow, the number of counterweight rings can be increased to ensure that the water extraction mechanism can sink stably and accurately sample. It can be widely used in various complex groundwater resource extraction scenarios. Compared with traditional fixed-structure extraction devices, it has stronger versatility and adaptability.

[0030] The present invention is further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention necessarily exceeds these limited embodiments. For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still fall within the scope of protection of the present application.

[0031] For example, see the attached Figure 1 - Figure 5 As shown, a groundwater resource extraction and detection device comprises three parts: a portable box, a winding mechanism and a water extraction mechanism;

[0032] The first part is a portable box, including a box shell 5 and an upper shell 501. A water quality analyzer 502 for detecting water quality is arranged inside the box shell 5. The water quality analyzer 502 is a known technology, so it will not be described in detail in the specification. The box shell 5 and the upper shell 501 are movably connected by a hinge for convenient opening and closing or operation convenience during water sample testing. The water quality analyzer 502 used in this technical solution is the LH-M7500 portable multi-parameter water quality analyzer.

[0033] The second part, a winding mechanism is arranged on one side of the inner part of the box shell 5, and the winding mechanism includes a motor 601 located inside the box shell 5, and a winding box body 6 at one end of the outer side of the box shell 5 corresponding to the motor 601, the front side wall of the winding box body 6 is hollow, the output shaft of the motor 601 extends to the inside of the winding box body 6 and is connected to a winding rod 602, a traction rope 603 is wound around the winding rod 602, the free end of the traction rope 603 extends outward from the front end opening of the winding box body 6, and the free end of the traction rope 603 is connected to a lock buckle 604;

[0034] The third part is a water extraction mechanism, which includes an extraction bottle 1 for storing aqueous solution and a filtering component for filtering floating impurities in groundwater. The top of the extraction bottle 1 is connected with a threaded sleeve 102 with an external thread. The filtering component includes a cylindrical filtering sleeve 2. The top of the filtering sleeve 2 is threadedly connected to a matching connecting cover 201. The connecting cover 201 is provided with anti-slip grooves to facilitate operators to carry out manual disassembly and assembly related operations during daily maintenance or component replacement, thereby reducing maintenance costs and difficulties. The outer side of the connecting cover 201 is connected with a connecting ring 202, wherein the winding component in the second part is connected to the connecting ring 202 through a lock buckle 604;

[0035] The filter sleeve 2 is provided with a small filter screen cylinder 3 and a medium filter screen cylinder 301 in sequence, and the small filter screen cylinder 3 and the medium filter screen cylinder 301 are arranged coaxially inside the filter sleeve 2, wherein the filter apertures of the filter sleeve 2, the medium filter screen cylinder 301, and the small filter screen cylinder 3 gradually decrease from the outside to the inside;

[0036] The water quality analyzer 502 is disposed inside the upper shell 501 of the box shell 5 and is connected to the extraction bottle 1 through a pipeline, and is used to analyze and detect the extracted and filtered water samples.

[0037] A docking port 203 is provided at the bottom of the filter sleeve 2, and a threaded sleeve 102 is installed at the top of the extraction bottle 1. The threaded sleeve 102 is connected to the internal thread of the docking port 203 to connect the extraction bottle 1 and the interior of the filter sleeve 2. The filter assembly allows the aqueous solution of the water area to be detected to penetrate into the interior of the filter sleeve 2 from the filter holes on the filter sleeve 2, and then filter through the filter holes on the medium-sized filter mesh cylinder 301 and the small filter mesh cylinder 3. The aqueous solution filtered by impurities will flow into the threaded sleeve 102 along the inside of the small filter mesh cylinder 3, and then flow into the interior of the extraction bottle 1; a charging port 7 is provided on the box shell 5.

[0038] When in use, the water quality analyzer 502 in the first part starts the winding assembly in the second part through the switch control, and the output shaft of the motor 601 in the winding assembly starts the winding rod 602, and the traction rope 603 on the winding rod 602 is released. At this time, the traction rope 603 extends downward, and the lock buckle 604 connected to the traction rope 603 is connected to the connecting ring 202. The traction rope 603 is gradually released from the winding rod 602, and the entire third part can be gradually sunk to the sampling water area. After sinking to the bottom, the water extraction mechanism is The filter assembly filters the aqueous solution in the test water area layer by layer. The filter holes on the outside of the filter sleeve 2, the medium-sized filter screen cylinder 301 and the small filter screen cylinder 3 are distributed inward in sequence inside the filter sleeve 2. As the diameters of the holes on the filter sleeve 2, the medium-sized filter screen cylinder 301 and the small filter screen cylinder 3 gradually decrease, the impurities that penetrate into the filter sleeve 2 along with the aqueous solution can be filtered layer by layer. The filtered aqueous solution flows from the inside of the small filter screen cylinder 3 through the threaded sleeve 102 into the extraction bottle 1. After the water extraction mechanism is sunk to the bottom of the water for a while,

[0039] The winding assembly is started to make the output shaft of the motor 601 rotate in the opposite direction, and the motor 601 drives the traction rope 603 to be rewound around the rewinding rod 602 for rewinding. As the traction rope 603 is rewound around the rewinding rod 602, the water extraction mechanism gradually rises until it is fished out of the water.

[0040] Separate the lock buckle 604 on the traction rope 603 from the connecting ring 202, rotate the filter sleeve 2 to separate the filter sleeve 2 and the threaded sleeve 102, pour the filtered aqueous solution in the extraction bottle 1 from the threaded sleeve 102 into the water quality analyzer 502 for water quality testing, and test the aqueous solution sampled by the water quality analyzer 502. After the test results come out, the entire water extraction mechanism can be placed in the box shell 5 for storage.

[0041] During routine maintenance, the filter assembly and the extraction bottle 1 in the water extraction mechanism can be detachably separated. During the last aqueous solution sampling operation, water was mixed with impurities inside the filter sleeve 2. The connecting cover 201 on the filter sleeve 2 can be opened, and the small filter mesh cylinder 3 and the medium filter mesh cylinder 301 can be pulled out to clean the residual impurities inside.

[0042] Furthermore, a circle of threaded grooves 101 is provided on the outer side of the bottom of the extraction bottle 1, and one or more groups of counterweight rings 4 are threadedly connected to the threaded grooves 101, which are used to increase or reduce the weight of the entire water extraction mechanism, so as to facilitate the rapid sinking of the water extraction mechanism in the detection water area. By adjusting the number or specifications of the counterweight rings 4, the overall weight distribution and sinking characteristics of the water extraction mechanism can be flexibly adjusted to adapt to groundwater resource extraction scenarios with different depths and water flow conditions. In shallow waters or areas with slow water flow, the number of counterweight rings 4 can be reduced; in deep waters or areas with turbulent water flow, the number of counterweight rings 4 is increased to ensure that the water extraction mechanism can sink stably and accurately sample. It can be widely used in various complex groundwater resource extraction scenarios, and compared with traditional fixed-structure extraction devices, it has stronger versatility and adaptability.

At the same time, check whether the relevant connection between the motor 601 and the water quality analyzer 502 is normal, and the traction rope 603 on the winding rod 602 is not abnormally entangled.

[0045] Sinking sampling: Turn on the switch, the water quality analyzer 502 controls the motor 601 to rotate forward, the reeling rod 602 rotates to release the traction rope 603, and the water extraction mechanism slowly sinks to the bottom of the water area to be tested through the traction rope 603 under the action of gravity. In this process, the aqueous solution is filtered through the filter assembly (filter sleeve 2, medium filter cylinder 301 and small filter cylinder 3) layer by layer and enters the extraction bottle 1.

[0046] Recover the water extraction mechanism: After the water extraction mechanism stays at the bottom of the water area for a certain period of time, the switch is operated again to reverse the motor 601, and the winding rod 602 begins to rewind the traction rope 603 to lift the water extraction mechanism upward from the water area to be tested until it is completely lifted out of the water.

[0047] Water sample testing: Separate the lock buckle 604 on the traction rope 603 from the connecting ring 202, then rotate the filter sleeve 2 to separate it from the threaded sleeve 102 of the extraction bottle 1, and pour the aqueous solution that has been filtered layer by layer inside the extraction bottle 1 from the threaded sleeve 102 into the water quality analyzer 502 for water quality testing.

[0048] Storage and arrangement: After recording the data according to the detection results of the water quality analyzer 502, clean the various components of the water extraction mechanism (if necessary, open the connection cover 201 of the filter sleeve 2, take out the small filter mesh cylinder 3 and the medium filter mesh cylinder 301 to clean the residual impurities inside), and then put the entire water extraction mechanism into the box shell 5 for storage and preservation for next use.
