Description

TECHNICAL FIELD

[0001] The present application relates to a deep water automatic water sampling device and a water sampling method, belonging to the technical field of deep water water sampling. BACKGROUND

[0002] China has abundant water resources, but with the development of social economy, water pollution problems are particularly prominent. Many petrochemical projects are located along the coast of rivers, lakes and densely populated cities, which pose a potential threat to water quality safety. Therefore, it is crucial to continuously and accurately monitor and assess water quality. Secondly, water pollution has a serious impact on the ecosystem and human health. Organic pollution and other prominent pollution types are hidden and difficult to control, causing long-term pollution to water bodies. Through hydrological and water quality detection, pollutants in water bodies can be detected in a timely manner, and their impact on the environment and human health can be predicted, so that appropriate measures can be taken to protect the ecological environment and human health. In addition, hydrological and water quality detection is also the basis for water resources management and planning. By understanding the status of water resources, scientific water use plans can be developed, water resources can be reasonably allocated, and the efficiency of water resources can be improved. At the same time, hydrological and water quality detection can also help to find and solve problems in water resources management, and promote the sustainable use of water resources. Therefore, it is particularly important to detect hydrology and water quality.

[0003] Currently, automatic water sampling technology has been widely applied and researched. For example, in rivers, lakes and other water areas, automatic samplers can collect water samples regularly and quantitatively, and online analysis instruments can monitor water quality indicators in real time. These data can help researchers understand the pollution status of water bodies and provide strong support for environmental protection and governance. In addition, with the development of Internet of Things, big data and other technologies, automatic water sampling technology is also constantly innovating and improving. For example, by combining automatic samplers with online analysis instruments, data transmission equipment and other devices, remote monitoring, real-time warning and data sharing functions can be realized, further improving the efficiency and accuracy of water quality monitoring.

DETAILED DESCRIPTION

[0039] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0040] like Figures 1-6 As shown, the present invention mainly includes a water collecting pipe 6, an iron fixture 10, a wing 5 and a direction controller 12. It is also equipped with a data detector 9 and a positioning signal transmitter 8. The water collecting pipe 6 can collect water samples, the iron fixture 10 is used to cooperate with the water collecting pipe 6 to achieve water intake, the direction controller 12 is used to adjust the movement direction of the equipment underwater, and the wing 5 adjusts the overall weight of the equipment by releasing water. The data detector 9 uses the MY18E20 high-precision temperature sensor chip to detect and store water temperature, water pressure and water depth data. The MS5837-30BA digital pressure sensor is used to measure water pressure and water depth, and is connected to the positioning signal transmitter. The data is transmitted to the GPS satellite through the positioning transmitter. The positioning signal transmitter 8 sends the location information of the device to the GPS in real time.

[0041] The water collecting pipe 6 is provided with a cover 2 at one end, which is usually made of iron and integrally formed with the water collecting pipe 6 to ensure the sealing. The other end is provided with an iron fixing device 10 and a water pumping device 25 in sequence. The water collecting pipe 6 is externally provided with a spring rod 14, an iron rod 7, a wing 5 and a tail wing 4. The water collecting pipe 6 is also provided with a pressurizing hole 15. The cover 2 can also be a piston which is spirally embedded in the water collecting pipe 6. The spiral structure makes the cover 2 better in sealing. In order to make the structure more stable, the water collecting pipe 6 is spirally embedded in the iron fixing device 10, that is, the iron fixing device 10 is spirally screwed on the water collecting pipe 6 to achieve the fixed connection and sealing. The iron fixing device 10 is longitudinally penetrated in the center. An inner wall of one end of the iron fixing device 10 facing the direction controller 12 is provided with a shoulder 27 extending inward and having a horizontal top surface. A circular hole formed in the center of the shoulder 27 is a water inlet hole 28. The inner wall of the water inlet hole 28 has a smaller diameter than the water collecting pipe 6. A plurality of telescopic rods 17 are uniformly arranged on the shoulder 27. An iron sheet 18 is fixed on the top of each telescopic rod 17. A sealing gasket 16 is arranged on the shoulder 27. The sealing gasket 16 plays a sealing role. When the telescopic rods 17 are retracted, the iron sheet 18 blocks the water inlet hole 28 in the center of the shoulder 27 and is tightly pressed on the sealing gasket 16 to form a blocking state. When the telescopic rods 17 are extended, the iron sheet 18 is pushed away from the sealing gasket 16. A gap is formed between the iron sheet 18 and the inner wall of the iron fixing device 10. Water enters the water inlet hole 28 through the gap between the fixed connecting blocks 26 and then enters the iron fixing device 10 and the water collecting pipe 6 through the gap between the iron sheet 18 and the inner wall of the iron fixing device 10 to form a water inlet channel 22. After the water collection is completed, the telescopic rods 17 are retracted and the iron sheet 18 is tightly pressed on the sealing gasket 16 to close the water inlet channel 22. A pressurizing hole 13 is arranged on the side wall of the water collecting pipe 6. A pressurizing device is connected before the water is discharged to pressurize the water collecting pipe 6. After the pressurization, the iron sheet 18 in the water collecting pipe 6 is pressed on the shoulder 27 to close the water collecting pipe 6.

[0042] Referring to Figure 2Before pressurizing, the motor does not work, and the telescopic rod is in a free state. When pressurizing, the motor does not work, and the air pressure in the water collecting pipe increases, the iron sheet is pressed downward, the telescopic rod is contracted, and the iron sheet is tightly pressed against the sealing gasket. When collecting water, the external water pressure is greater than the air pressure in the water collecting pipe (when the device is in use, the air pressure in the water collecting pipe is usually equal to the water pressure at the sampling position. The telescopic rod is driven by the motor to open the iron sheet. If the sampling requirement is not high, the air pressure in the water collecting pipe can be slightly less than the water pressure at the sampling position. Through the pressure difference, the device reaches the sampling depth and is automatically opened under the action of the pressure difference to sample. ), the iron sheet starts to move upward, and the water collecting pipe starts to collect water. After the water collection is completed, the motor starts to work to pull back the telescopic rod, and the iron sheet is tightly attached to the sealing gasket again. The device is provided with a water pressure sensor on the side of the iron sheet facing the water collecting pipe 6. When the water collecting pipe 6 is full of water, the water pressure sensor triggers the motor to act, and the telescopic rod is closed. In the water sampling mode of driving the telescopic rod by the motor to open the iron sheet, the iron sheet can also be closed by setting the triggering time of the motor twice. Set the sampling time, the first time is to reach the sampling depth, trigger the motor to open the iron sheet, and the motor automatically closes the iron sheet when the opening time reaches the sampling time.

[0043] In order to ensure the safety of the water collecting pipe 6 under water and prevent it from deforming or vibrating, a spring rod and an iron rod are coaxially arranged outside the water collecting pipe 6. The iron rod has two fixed lengths and is connected and fixed to the cover 2 and the iron fixing device 10 at the upper and lower ends of the iron rod 7, thereby stably connecting the water collecting pipe 6, the cover 2 and the iron fixing device 10. Meanwhile, the iron rod 7 is fixed outside the device and can bear part of the pressure, thereby preventing the device from deforming greatly under the action of the huge water pressure. The spring rod 14 is arranged on one side of the water collecting pipe 6 and can replace spring rods with different elastic limits. Under the action of the huge water pressure, the spring rod is used to stabilize the instrument itself and prevent the instrument from deforming due to the change of the water pressure. By opening and closing the external spring rod switch, spring rods with different elastic limits can be replaced, thereby adapting to the severe vibration of the instrument caused by the pressure difference in the sinking process and achieving the purpose of vibration reduction. The spring rod is a spring rod inserted into two rings arranged outside the water collecting pipe 6. One of the rings is provided with a spring switch. After the spring rod is inserted to a preset position, the spring rod is fixed by the spring rod switch 11. The spring rod switch 11 has a clamping structure like an adjusting nut or a bolt structure. When it is necessary to replace the spring rod 14 according to the water depth and the water quality of the water flow at the sampling position and other comprehensive information, the spring rod switch 11 is opened, the original spring rod 14 is removed, the required spring rod 14 is replaced, and then the spring rod switch 11 is closed.

[0044] The wing 5 is streamlined, similar to a fish fin on both sides of the water collector 6, hollow inside, which can drain water. The tail 4 is streamlined, similar to a fish tail on one side of the water collector 6, which plays a role in reducing resistance and underwater gliding. The wing 5 and the tail 4 are both hollow structures. The wing 5 is used to store water, adjust the weight of the equipment, and sink the equipment, and after the water sampling is completed, the equipment is floated by draining water. The tail 4 is always empty, providing buoyancy for the equipment to float to the surface. When the water in the wing 5 is almost gone, the water pressure expeller 23 has difficulty draining water, and the equipment approaches a flat state. Relying on the hollow structure of the tail 4, the buoyancy is provided to ensure that the equipment can float to the water surface.
