Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, and in particular to an ammonia nitrogen sampling device for ecological and environmental water quality testing. Background Technology

[0002] Water quality testing is an essential component of environmental impact assessments for engineering projects, water resource development and utilization, water environment management projects, and water environment-related scientific research. Through water quality testing, the types and concentrations of substances contained in a target water body can be identified, enabling analysis of the current state of the water environment, the impact of engineering projects, and the study of pollutant migration and transformation patterns. Given the necessary testing conditions, such as equipment and personnel, the first step is to obtain water samples from the target water body. These samples are then brought back and tested using appropriate instruments to draw conclusions.

[0003] A search revealed that application number 202022922944.8 discloses a water quality sampling device, belonging to the field of environmental monitoring technology. The water quality sampling device includes: a support member, a suspension member, and a water sampler connected in sequence; the water sampler includes at least two water buckets arranged side-by-side, and a connecting plate; the top of each water bucket is closed and connected to the connecting plate, which is suspended from the suspension member; an inlet is located near the top of each water bucket, and a spring-loaded sealing device is connected to the outer wall of the water bucket to seal the inlet. This utility model's water quality sampling device, with its support member, suspension member, and water sampler connected in sequence, and the water sampler including at least two water buckets, achieves water quality sampling accuracy through the sealing cooperation of the spring-loaded sealing device and the inlet. Furthermore, by adjusting the suspension member to sample water at different depths, the efficiency of water quality sampling is improved.

[0004] Although the aforementioned equipment can sample water at different depths, it can only sample from one depth at a time. The sample needs to be removed and then re-submerged in the water for a second sampling. It cannot sample multiple different depths at once for testing, making it cumbersome to use. Utility Model Content

[0005] This utility model discloses an ammonia nitrogen sampling device for ecological and environmental water quality testing, aiming to solve the technical problem that although it can sample water at different depths, it can only sample from one depth at a time, and the sample needs to be taken out and put back into the water for secondary sampling. It is impossible to sample multiple different depths at the same time for testing, which is cumbersome.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A sampling device for ammonia nitrogen in ecological and environmental water quality testing includes a housing. An air cushion is detachably mounted on the outside of the housing, and a detection component is disposed inside the housing. The detection component includes a box body fixedly installed on the inner bottom wall of the housing. A plurality of sampling pipes are fixedly passed through the outer wall of the box body. Each sampling pipe is equipped with a valve, and all sampling pipes are connected to a first pipe. The first pipe is connected to a second pipe, which is connected to a storage tank. A second water pump is disposed within the second pipe. A third pipe is connected to the storage tank. Three pipes are connected to the detection port of the water quality analyzer, which is fixedly connected to the inner wall of the housing. A valve is provided to control several sampling pipes, controlling the opening and closing of one sampling pipe and the closing of the remaining sampling pipes. Under the action of the second water pump, the water flows into the storage tank and is located inside the detection chamber. Under the action of the fourth water pump, the sampled water is transported to the water quality analyzer through the third pipe for testing, and the results of the sampling analysis are saved in real time. After the test is completed, the water in the detection chamber is discharged into the storage chamber by the third water pump, and then the next depth of water quality testing is carried out.

[0008] Preferably, a sealing ring is provided at the connection between the sampling pipe and the housing; a fourth water pump is provided inside the third pipe, and the sealing ring keeps the inside of the housing closed to prevent water from flowing into the equipment, so that the equipment can sink into the water as a whole under its own weight.

[0009] Preferably, the storage box is equipped with a partition, which divides the storage box into a detection chamber and a storage chamber. The storage box is equipped with a third water pump and a first water pump. The inlet of the third water pump extends into the detection chamber and the outlet is located in the storage tank. The inlet of the first water pump is located in the storage tank and the outlet extends to the outside of the casing. The sampled water is transported to the water quality analyzer for testing through a third pipe, and the results of the sampling analysis are saved in real time. After the test is completed, the water in the detection chamber is discharged into the storage chamber by the third water pump, and then the water quality test at the next depth is carried out. When the storage chamber is full of water, the water is discharged to the outside by the third water pump.

[0010] Preferably, the end of the third pipe extends into the storage tank, and the end is located on the side of the partition closer to the first water pump.

[0011] Preferably, the end of the sampling tube extends to the bottom of the housing.

[0012] Preferably, the housing is equipped with an air pump, the output port of which is connected to a fourth pipe, which is connected to the air cushion.

[0013] Preferably, the housing has slots on both sides, the air cushion is detachably connected to the slots, the housing has a cover door, and the housing also has a pull tab.

[0014] As can be seen from the above, the ammonia nitrogen sampling device for ecological environment water quality testing provided by this utility model has the following technical effects.

[0015] Firstly, during use, the air cushion is inflated by an air pump, causing it to float on the water surface. At this time, the sampling pipe can sample the water quality of the lake surface. When the gas inside the air cushion is discharged to the outside by the air pump, the casing is sealed, and the device sinks into the water by its own weight. During the sinking process, water quality samples at different depths can be extracted through the sampling pipe for real-time detection, which solves the problems mentioned in the background technology and has practicality.

[0016] Secondly, the valves can control several sampling pipes, opening and closing one pipe and closing the rest. Under the action of the second pump, the water flows into the storage tank. Inside the detection chamber, under the action of the fourth pump, the sampled water is transported to the water quality analyzer via the third pipe for testing. The results of the sampling analysis are saved in real time. After testing, the third pump discharges the water from the detection chamber into the storage chamber for further water quality testing at the next depth. When the storage chamber is full, the third pump discharges the water to the outside. This allows the equipment to sample and test groundwater in different areas, improving its practicality.

[0025] Reference Figures 1-5 A sampling device for ammonia nitrogen in ecological water quality testing includes a housing 2, with a detachable air cushion 1 on the outside of the housing 2 and a detection component 3 inside the housing 2. The detection component 3 includes a box 301, which is fixedly installed on the inner bottom wall of the housing 2. Several sampling pipes 4 are fixedly inserted through the outer wall of the box 301. Each sampling pipe 4 is equipped with a valve 303, and all sampling pipes 4 are connected to a first pipe 304. The first pipe 304 is connected to a second pipe 306, which is connected to a storage tank 307. A second water pump 305 is installed inside the second pipe 306. A third pipe 309 is connected to the storage tank 307. 309 is connected to the detection port of the water quality analyzer 308, which is fixedly connected to the inner wall of the housing 301. The valve 303 can control several sampling pipes 4, controlling the opening and closing of one sampling pipe 4 and the closing of the remaining sampling pipes 4. Under the action of the second water pump 305, the water flows into the storage tank 307 and is located inside the detection chamber. Under the action of the fourth water pump, the sampled water is transported to the water quality analyzer 308 for detection through the third pipe 309, and the sampling analysis results are saved in real time. After the detection is completed, the water in the detection chamber is discharged into the storage chamber by the third water pump 312, and then the next depth of water quality detection is carried out.

[0026] In this embodiment, a sealing ring 302 is provided at the connection between the sampling pipe 4 and the housing 301; a fourth water pump is provided inside the third pipe 309, and the sealing ring 302 keeps the inside of the housing 2 closed to prevent water from flowing into the equipment, so that the equipment can sink into the water as a whole by its own weight.

[0027] In this embodiment, a partition 310 is provided inside the storage box 307, dividing the storage box 307 into a detection chamber and a storage chamber. The storage box 307 is equipped with a third water pump 312 and a first water pump 311. The input port of the third water pump 312 extends into the detection chamber and the output port is located in the storage tank. The input port of the first water pump 311 is located in the storage tank and the output port extends to the outside of the housing 2. The sampled water is transported to the water quality analyzer 308 for detection through the third pipe 309, and the results of the sampling analysis are saved in real time. After the detection is completed, the water in the detection chamber is discharged into the storage chamber through the third water pump 312, and then the next depth of water quality detection is carried out. When the storage chamber is full of water, the water is discharged to the outside through the third water pump 312. The detection time for COD of water quality is about 20 minutes, and the detection time for turbidity is usually about 1 minute. This device is not suitable for more comprehensive water quality parameter detection, but only for short-term portable detection. The model of the water quality analyzer 308 is "MI-80B".

[0028] In this embodiment, the end of the third pipe 309 extends into the storage tank 307, and the end is located on the side of the partition 310 near the first water pump 311.

[0029] In this embodiment, the end of the sampling pipe 4 extends to the bottom of the housing 2. It sinks continuously due to the weight of the iron box and eventually suspends at a certain depth, allowing water quality to be sampled between the water surface and the suspension height. Depending on the testing requirements, a weight block can be added inside the iron box to change the suspension height, so as to sample water quality at different depths.

[0030] In this embodiment, an air pump 5 is installed inside the housing 2. The output port of the air pump 5 is connected to a fourth pipe 6, which is connected to the air cushion 1. When in use, the air cushion 1 is inflated by the air pump 5, making it float on the water surface. At this time, the sampling pipe 4 can sample the water quality of the lake surface. When the gas in the air cushion 1 is discharged to the outside through the air pump 5, the housing 2 is sealed. The device sinks into the water by its own weight. During the sinking process, water quality samples at different depths can be extracted through the sampling pipe 4.

[0031] In this embodiment, the housing 2 has slots 203 on both sides, and the air cushion 1 is detachably connected to the slots 203. The housing 2 is provided with a cover door 202 and a pull buckle 201. The pull buckle 201 can be connected to a distance measuring traction machine on the shore. The distance measuring traction machine consists of a winding reel and a traction rope. The water level of the equipment can be controlled by loosening and releasing the length of the traction rope. Alternatively, the equipment can be lowered into the water from the boat where the staff is riding using a hoisting rope, and the depth of the equipment in the water can be determined by the length of the rope below.

[0032] Working principle: During use, the air cushion 1 is inflated by the air pump 5, making it float on the water surface. At this time, the sampling pipe 4 can sample the water quality of the lake surface. When the gas in the air cushion 1 is discharged to the outside through the air pump 5, the casing 2 is sealed and the device sinks into the water by its own weight. During the sinking process, water quality samples at different depths can be extracted through the sampling pipe 4 for real-time detection, which solves the problems mentioned in the background technology and has practicality.

[0033] The valve 303 can control several sampling pipes 4, opening and closing one sampling pipe 4 and closing the remaining sampling pipes 4. Under the action of the second water pump 305, the water flows into the storage tank 307. Inside the detection chamber, under the action of the fourth water pump, the sampled water is transported to the water quality analyzer 308 through the third pipe 309 for testing. The results of the sampling analysis are saved in real time. After the test is completed, the water in the detection chamber is discharged into the storage chamber by the third water pump 312, and then the water quality test at the next depth is carried out. When the storage chamber is full of water, the water is discharged to the outside by the third water pump 312. This allows the equipment to sample and test groundwater in different areas, improving the practicality of the equipment.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
