Description

Technical Field

[0001] The invention relates to the technical field related to groundwater treatment, and in particular to a pretreatment structure for groundwater quality sample detection. Background Art

[0002] Groundwater refers to water stored in the rock voids below the ground. In a narrow sense, it refers to water in the saturated aquifer below the groundwater surface. Groundwater quality testing refers to the method of applying chemical or other testing technologies to determine the content of each component in groundwater. It can solve various hydrogeological theories and practical problems and provide water quality data. When testing groundwater quality, the extracted groundwater needs to be pretreated to remove impurities that are irrelevant to the test results (generally floating leaves and dead branches, etc.). At this time, corresponding pretreatment structures and devices are generally used.

[0003] The existing Chinese patent application with publication number CN113511695A discloses a water sample pretreatment device for water quality detection, including a tank body and a tank cover, wherein a circumferential side wall of the tank cover is fixed with a side ring, and the circumferential inner side wall of the side ring is in contact with the circumferential outer side wall of the tank body; a plurality of mounting grooves are provided on the circumferential inner side wall of the side ring, mounting springs are fixed in the mounting grooves, mounting blocks are slidably connected in the mounting grooves, the mounting springs are fixed to the mounting blocks, a plurality of connecting grooves for inserting the mounting blocks are provided on the circumferential outer side wall of the tank body, the mounting blocks are located in both the mounting grooves and the connecting grooves, and the mounting blocks are located on the lower surface of the mounting grooves Inclined setting; a sealing component is provided between the tank cover and the tank body to seal the two; an unlocking component is provided on the tank cover for simultaneously allowing all mounting blocks to fully enter the corresponding mounting grooves; the invention buckles the tank cover on the top of the tank body, and the mounting blocks are squeezed and enter the mounting grooves, and are fixed when one end of the mounting blocks is inserted into the connecting groove. After all the mounting blocks are fully entered into the mounting grooves by the unlocking component, the tank cover can be pulled out from the tank body, thereby improving the opening and closing efficiency of the tank body; the setting of the edge ring and the sealing component improves the sealing between the tank body and the tank cover, thereby making the pretreatment effect better.

[0004] The existing Chinese patent application with publication number CN116062864A discloses a water treatment device with a water quality monitoring function, including a water tank and a reaction tank arranged above the water tank, wherein a stirring assembly is arranged in the reaction tank, and further comprising: a water quality monitoring device, arranged on the stirring assembly for monitoring the water quality in the reaction tank; a flocculant adding device, arranged on the top of the water tank for adding flocculant to the reaction tank; a filtering device, wherein the filtering device comprises an annular filter plate installed on the inner wall of the bottom of the reaction tank; the invention realizes a large-scale water quality detection of sewage water quality, and as the sewage treatment proceeds and as the reaction proceeds, the water quality detected by the water quality detector can be used to more accurately control the amount of flocculant added, and can be applied to sewage treatment with different pollution levels, to realize the separation of treated water and sediment, and to automatically clean up the sediment, which greatly improves the convenience of water treatment, saves labor, and improves water treatment efficiency.

[0005] However, the groundwater quality pretreatment structure has the following defects when used specifically:

[0006] 1. The existing groundwater quality pretreatment structure generally adopts a filtering and separation method to separate the impurities (floating leaves and dead branches, etc.) in the groundwater that are irrelevant to the water quality detection when treating the collected groundwater. However, in actual operation, the impurities to be separated will be stuck in the mesh of the separation filter, and with the impact of water, the filter will be damaged. At the same time, some impurities such as gravel with smaller particles cannot be screened through the mesh. In subsequent detection, these impurities are easy to cause the reagent tube storing the water quality sample to be damaged due to collision during the shaking step in the subsequent detection operation, affecting the subsequent water quality detection operation.

[0007] 2. The existing groundwater quality pretreatment structure is large in size and inconvenient to carry when pretreating the collected groundwater. At this time, the traditional method of use generally collects the groundwater and moves it to the laboratory through a storage device to classify water quality samples and test the classified samples. This is not convenient enough. At the same time, the carried groundwater cannot classify a sufficient amount of samples, resulting in a small number of samples tested and inaccurate test results.

The connecting protrusion 1105 is installed on the inner side of the telescopic component 1106. The telescopic component 1106 is slidably connected to the inside of the connecting tube 1102 and is located at the top of the rotating shaft 1103; the vibration protrusion 1107 is installed and fixed on the top of the telescopic component 1106 and extends to the outside of the connecting tube 1102. The vibration protrusion 1107 is located below the external frame 901 and drives the external frame 901 to vibrate.

[0090] In this embodiment, the raceway 1104 is arranged in a wave shape on the inner wall of the rotating shaft 1103, and the telescopic part 1106 is arranged in a "concave" shape. Through the design of the raceway 1104, when the rotating shaft 1103 rotates, the telescopic part 1106 connected to the inner side through the connecting protrusion 1105 can be telescopically moved.

[0091] At the same time, in this embodiment, the top of the vibration protrusion 1107 is set in an arc shape, and the material of the top is rubber. The design of the vibration protrusion 1107 can reduce the degree of damage to the external frame 901 when the vibration protrusion 1107 collides and squeezes the external frame 901.

[0092] The pretreatment structure for detecting underground water quality samples of the present invention is as follows: when the micro motor 1002 is in operation, the rotating shaft 1101 installed on the top of the output end thereof will rotate, and drive the rotating shaft rod 1103 installed on the top of the rotating shaft 1101 to rotate; when the rotating shaft rod 1103 is rotating, it will drive the connecting protrusion 1105 whose inner wall is connected through the raceway 1104 to slide inside the raceway 1104, and drive the telescopic component 1106 connected to the connecting protrusion 1105 to perform telescopic movement (reciprocating telescopic movement), thereby driving the vibrating convex rod 1107 installed on the top of the telescopic component 1106 to perform telescopic movement, so that the external frame 901 on the top of the vibrating convex rod 1107 can move, wherein the extension block 903 connected to the side of the external frame 901 can slide inside the connector 904, so that the screening net 902 can vibrate, thereby reducing the probability of impurities being stuck in the mesh inside the screening net 902.
