Description

Technical Field

[0001] This utility model relates to the field of water quality sampling technology, specifically a stratified water quality testing device for environmental impact assessment. Background Technology

[0002] A stratified water quality testing device for environmental impact assessment (EIA) is disclosed in CN219122181U. It includes a main body, a cleaning mechanism, a winding mechanism, and a connecting mechanism. The cleaning mechanism is located at the inner end of the main body, the winding mechanism at the outer end, and the connecting mechanism inside the winding mechanism. The connecting mechanism includes a counterweight, a supplementary weight, an assembly block, an adjusting rod, a return spring, a limiting block, a locking block, a locking groove, and a limiting slot. The supplementary weight is movably mounted on the outer end of the counterweight, the assembly block is movably mounted on the outer end of the supplementary weight, and the adjusting rod is fixedly mounted on the front end of the assembly block. In this stratified water quality testing device for EIA, the counterweight and supplementary weight can be added to the outside of the connecting pipe, allowing the connecting pipe to smoothly penetrate underwater for sampling. This enables the device to conveniently sample water quality at different levels for comparative testing, thus increasing the effectiveness of the EIA testing.

[0003] Although this technical solution for a stratified water quality testing device for environmental impact assessment can improve the effectiveness of environmental impact assessment testing, its shortcomings are also more obvious. For example, when personnel take samples from water sources at different depths, they rely solely on connecting pipes to continuously descend underwater to take samples. This process requires personnel to repeatedly change storage devices, making the steps cumbersome and affecting sampling efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a stratified water quality testing device for environmental impact assessments. It solves the problem that when personnel sample water sources at different depths, the process relies solely on connecting pipes continuously descending underwater for sampling, requiring personnel to repeatedly change storage devices, resulting in cumbersome procedures and reduced sampling efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stratified water quality testing device for environmental impact assessment, comprising an installation plate, a protective frame fixedly connected to the top of the installation plate, a baffle fixedly connected to the middle of the inner wall of the protective frame, a water pump fixedly installed on one side of the baffle, a delivery pipe inserted into the output end of the water pump, automatic delivery components equidistantly arranged on the surface of the delivery pipe, a connector inserted into the input end of the water pump, a drain pipe inserted into one end of the connector, and an extraction head inserted into one end of the drain pipe.

[0006] In one specific embodiment, the automatic conveying assembly includes a sampling tube inserted into the surface of the conveying tube, an electric valve is provided at the top of the sampling tube, and a sealing ring is fixedly connected to one end of the sampling tube.

[0007] In one specific embodiment, a sampling bottle is inserted into the center of one end of the sampling tube, and a transparent plate is embedded on one side of the sampling bottle.

[0008] In one specific embodiment, the top of the sampling bottle is provided with an extraction hole, and a plug is threaded into the extraction hole.

[0009] In one specific embodiment, the top of the electric valve is electrically connected to a power cord, and one end of the power cord is plugged into a controller.

[0010] In one specific embodiment, the back of the controller is fixedly connected to the surface of the protective frame, and an indicator light is provided in the center of the front of the controller.

[0011] In one specific embodiment, a top cover is snapped onto the top of the protective frame, and a battery block is disposed on the top of the top cover.

[0012] Compared with the prior art, this utility model provides a stratified water quality testing device for environmental impact assessment, which has the following beneficial effects:

[0013] In the technical solution disclosed in this utility model, by using the cooperation of an automatic conveying component, a water pump and an extraction head, when personnel need to sample water sources at different depths, they can directly place the extraction head at the position to be tested, and then the personnel can turn on the power of the water pump, so that the water source conveying pipe delivers the water to the inside of the sampling pipe. Then, the personnel can use the controller to turn on the power of different electric valves, which makes it convenient for personnel to perform layered sampling inside water sources at different depths.

[0014] The sampling tube of this invention has a sampling bottle inserted into the axial center of one end. A transparent plate is embedded on one side of the sampling bottle, and an extraction hole is opened on the top of the sampling bottle. A plug is threaded into the extraction hole. During the sampling process, the sampling tube delivers water to the inside of the sampling bottle, making it convenient for the testing personnel to take samples one by one from water sources at different depths. Then, the personnel can unscrew the plug to open the sampling bottle, making it convenient for the personnel to take out the water sample. Attached Figure Description

A protective frame 2 is fixedly connected to the top of the mounting plate 1. A baffle 3 is fixedly connected to the middle of the inner wall of the protective frame 2. A water pump 4 is fixedly installed on one side of the baffle 3. A delivery pipe 5 is inserted into the output end of the water pump 4. Automatic delivery components 6 are equidistantly arranged on the surface of the delivery pipe 5. A connector 7 is inserted into the input end of the water pump 4. A drain pipe 8 is inserted into one end of the connector 7. An extraction head 9 is inserted into one end of the drain pipe 8.

[0023] The specific problem addressed in this embodiment is the inefficiency of sampling water at different depths when personnel rely solely on connecting pipes to continuously descend underwater for sampling, requiring repeated changes of storage equipment. This invention utilizes the coordinated use of an automatic conveying component 6, a water pump 4, and an extraction head 9. When sampling water at different depths, personnel can directly place the extraction head 9 at the desired testing position. Then, the water pump 4 is powered on, allowing the water delivery pipe 5 to transport the water to the sampling pipe 61. Subsequently, the controller 14 can be used to activate the power to different electric valves 62, facilitating stratified sampling at different depths.

[0024] The automatic conveying assembly 6 includes a sampling tube 61 inserted into the surface of the conveying pipe 5. An electric valve 62 is provided at the top of the sampling tube 61, and a sealing ring 63 is fixedly connected to one end of the sampling tube 61.

An extraction hole is opened at the top of the sampling bottle 10, and a plug 12 is threaded inside the extraction hole. A power cord 13 is electrically connected to the top of the electric valve 62, and a controller 14 is inserted into one end of the power cord 13. During the sampling process, the sampling tube 61 delivers water to the inside of the sampling bottle 10, making it convenient for the testing personnel to sample water at different depths. Subsequently, the personnel can unscrew the plug 12 to open the sampling bottle 10, making it convenient for the personnel to take out the water sample.

[0025] In this specific embodiment, the back of the controller 14 is fixedly connected to the surface of the protective frame 2. An indicator light is provided in the center of the front of the controller 14. A top cover 15 is snapped onto the top of the protective frame 2. A battery block 16 is provided on the top of the top cover 15. The battery block 16 facilitates the supply of power to the inside of the water pump 4.
