Description

Technical Field

[0001] The invention relates to deep water automatic water sampling equipment and a water sampling method, belonging to the technical field of deep water sampling. Background Art

[0002] my country has abundant water resources, but with the development of social economy, water pollution is particularly prominent. Many petrochemical projects are located along rivers, lakes and densely populated cities, posing a potential threat to water quality safety. Therefore, it is essential to continuously and accurately monitor and evaluate water quality. Secondly, water pollution has a serious impact on both the ecosystem and human health. Prominent pollution types such as organic pollution are deeply hidden and difficult to control, causing long-term pollution to water bodies. Through hydrological and water quality testing, pollutants in water bodies can be discovered in time, their impact on the environment and human health can be predicted, and corresponding measures can be taken to protect the ecological environment and human health. In addition, hydrological and water quality testing is also the basis for water resources management and planning. By understanding the status of water resources, scientific water use plans can be formulated, water resources can be reasonably allocated, and the utilization efficiency of water resources can be improved. At the same time, hydrological and water quality testing can also help to discover and solve problems in water resources management and promote the sustainable use of water resources. Therefore, it is particularly important to test hydrological and water quality.

[0003] At present, the technology of automatic water sampling has been widely used and studied. For example, in rivers, lakes and other water bodies, water samples can be collected regularly and quantitatively through automatic samplers, and water quality indicators can be monitored in real time through online analytical instruments. 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 technologies such as the Internet of Things and big data, the technology of automatic water sampling is also constantly innovating and improving. For example, by combining automatic samplers with online analytical instruments, data transmission equipment, etc., functions such as remote monitoring, real-time warning and data sharing can be realized, further improving the efficiency and accuracy of water quality monitoring.

[0024] Step 6: While the water collecting pipe (6) is collecting water, the pressurized drainer (23) discharges the water in the wing (5), ensuring that the deep-water automatic water collection equipment is balanced in force and can collect water at a specified depth;

[0026] Step 8: When the water collection is completed, the telescopic rod (17) is retracted, and the iron sheet (18) is pressed tightly against the sealing gasket (16) to seal and store the water in the water collection pipe (6);

[0027] Step 9: The wings on both sides continue to drain water, so that the buoyancy of the deep-water automatic water sampling equipment is greater than the gravity, and the deep-water automatic water sampling equipment floats up;

[0028] Step 10: The deep-water automatic water sampling equipment floats to the water surface and is recovered.

DETAILED DESCRIPTION

[0039] The present invention is further explained 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 used to limit the scope of the present invention.

[0040] like Figure 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 inlet, the direction controller 12 is used to adjust the moving direction of the equipment underwater, and the wing 5 adjusts the overall weight of the equipment by releasing water. The data detector 9 adopts 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 the 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 following is a detailed introduction to the water collecting pipe 6. A cover 2 is provided at one end of the water collecting pipe 6. The cover 2 is usually an iron cover, which is integrally formed with the water collecting pipe 6 to ensure sealing. An iron fixture 10 and a water suction device 25 are provided at the other end in sequence. A spring rod 14, an iron rod 7, a wing 5, and a tail 4 are provided on the outside of the water collecting pipe 6. The water collecting pipe 6 is also provided with a pressurized hole 15. The cover 2 can also be a piston, which is spirally embedded in the water collecting pipe 6. The spiral structure makes it more sealed. In order to make the structure more stable. The water collecting pipe 6 adopts a spiral embedded iron fixture 10, that is, the iron fixture 10 is spirally tightened and sleeved with the water collecting pipe 6, which plays a role of fixed connection and sealing. The center of the iron fixture 10 is longitudinally penetrated, and the inner wall of the iron fixture 10 facing the direction controller 12 is provided with a circle of shoulders 27 extending inward and with the top surface horizontal. The circular hole formed in the center of the shoulder 27 is the water inlet hole 28, and the inner wall diameter of the water inlet hole 28 is smaller than the diameter of the water collecting pipe 6. A plurality of telescopic rods 17 are evenly arranged on the circumference of the shoulder 27, and an iron sheet 18 is fixed on the top of the telescopic rod 17. A sealing gasket 16 is laid on the shoulder 27, and the sealing ring of the sealing gasket 16 plays a sealing role. When the telescopic rod 17 is retracted, the iron sheet 18 blocks the water inlet hole 28 at the center of the shoulder 27, and is tightly pressed on the sealing gasket 16, forming a blocking state; when the telescopic rod 17 is extended, the iron sheet 18 is pushed away from the sealing gasket 16, and a gap appears between the iron sheet 18 and the inner wall of the iron fixture 10, and water enters the water inlet hole 28 through the gap between the fixed connection block 26, and then enters the iron fixture 10 and the water collecting pipe 6 from the gap between the iron sheet 18 and the inner wall of the iron fixture 10, forming a water inlet channel 22; after the water is collected, the telescopic rod 17 is retracted, and the iron sheet 18 is pressed on the sealing gasket 16, closing the water inlet channel 22. A pressurizing hole 13 is opened on the side wall of the water collecting pipe 6. Before launching, a pressurizing device is connected to pressurize the water collecting pipe 6. After pressurization, the iron sheet 18 in the water collecting pipe 6 is pressed onto the shoulder 27, closing the water collecting pipe 6.

[0042] See also Figure 2, before pressurizing and pumping, the motor does not work, and the telescopic rod is in a free moving state. When pressurizing and pumping, the motor does not work, the air pressure in the water collecting pipe increases, the iron sheet is squeezed downward, the telescopic rod shrinks, and the iron sheet is 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 patented device is in use, the air pressure in the water collecting pipe is usually equal to the water pressure at the sampling point, and the telescopic rod is driven by the motor to open the iron sheet. If the collection requirements are not high, the air pressure in the water collecting pipe can be made slightly lower than the water pressure at the sampling point. Through the pressure difference, the equipment reaches the sampling depth and automatically opens the iron sheet under the action of the pressure difference for sampling.), the iron sheet begins to move up, and the water collecting pipe begins to collect water. After the water collection is completed, the motor starts to work, pulls back the telescopic rod, and the iron sheet is again close to the sealing gasket. The device of the present invention sets a water pressure sensor on the side of the iron sheet facing the water collecting pipe 6. When the water in the water collecting pipe 6 is full of water, the water pressure sensor triggers the motor to move and close the telescopic rod. In the water sampling method of opening the iron sheet by driving the telescopic rod with a motor, the motor can also be set to trigger twice before and after to close the iron sheet. The sampling time is set. The first time is when the sampling depth is reached, the motor is triggered to open the iron sheet. When the opening time reaches the sampling time, the motor automatically closes the iron sheet.

[0043] In order to ensure the safety of the water collecting pipe 6 underwater and prevent it from deforming or vibrating, a spring rod and an iron rod are coaxially arranged outside the water collecting pipe 6. There are two iron rods, which are distributed on both sides of the water collecting pipe 6. The two iron rods are of fixed length. The upper and lower ends of the iron rod 7 are respectively connected and fixed with the cover 2 and the iron fixture 10, which play a role in firmly connecting the water collecting pipe 6, the cover 2 and the iron fixture 10. At the same time, the iron rod 7 is fixed outside the equipment to bear part of the pressure for the equipment, and prevent the equipment from being greatly deformed under the action of the huge underwater pressure. The spring rod 14 can replace spring rods with different elastic limits on one side of the water collecting pipe 6. Under huge water pressure, the spring rod is used to stabilize the instrument itself to prevent the change of water pressure from causing the instrument to deform. By opening and closing the external spring rod switch, the spring rod with different elastic limits is replaced to adapt to the violent vibration of the instrument caused by the pressure difference during the sinking process, so as to achieve the purpose of vibration reduction. The spring rod is a rod with a spring section. Two rings are arranged outside the water collecting pipe 6. The spring rod is inserted into the two rings. A spring switch is arranged in one of the rings. After the spring rod is inserted into the preset position, the spring rod is fixed by the spring rod switch 11. The spring rod switch 11 is a clamping structure or a latch structure like an adjustment nut. When the spring rod 14 needs to be replaced according to the comprehensive information such as the water depth and the water quality at the water collection point, the spring rod switch 11 is opened, the original spring rod 14 is removed, and the required spring rod 14 is replaced, and then the spring rod switch 11 is closed.

[0044] The wing 5 is streamlined, on both sides of the water collecting pipe 6, similar to a shark fin, and hollow inside to drain water. The tail 4 is streamlined, on one side of the water collecting pipe 6, similar to a fish tail, and plays a role in reducing resistance and gliding underwater. The wing 5 and the tail 4 are both hollow structures. The wing 5 is used to hold water, adjust the weight of the equipment, and is used to sink the equipment, and after the water collection is completed, the equipment is floated by releasing water. The tail 4 is always empty to provide buoyancy for the equipment to float up. When the water in the wing 5 is drained to a minimum, the pressurized drainer 23 has difficulty draining water, and the equipment is close to a lying state. Relying on the cavity structure of the tail 4, buoyancy is provided to ensure that the equipment can float to the water surface.

[0045] The following is a detailed introduction to the structure of the data detector: The data detector is an electronic detector that can detect and store water pressure and water temperature data. It is fixed on an iron fixture. The MY18E20 high-precision temperature sensor chip is used to measure water temperature, and the MS5837-30BA digital pressure sensor is used to measure water pressure and depth. Both are connected to the positioning signal transmitter, and the data is transmitted to the GPS satellite through the positioning transmitter.

[0046] The following is a detailed introduction to the structure of the positioning signal transmitter: The positioning signal transmitter is an electronic transmitter with a GPS positioning system that can transmit signals to GPS satellites. It is fixed on an iron fixture at the same location as the data detector. The model McMurdo SmartFind s20 can be used, which has a built-in GPS and 406MHz satellite communication module, which can automatically activate in deep water and send accurate location information.

[0047] The structure of the direction controller 12 is described in detail below: it includes a closed-loop channel 20, a metal ball 19, and a water extractor 21; the metal ball 19 is made of iron or steel, the closed-loop channel 20 can be evacuated to form a vacuum space, the metal ball 19 is placed in the closed-loop channel 20, and can move to change the center of gravity of the device, and then change the direction of movement, the vacuum environment can reduce air resistance and reduce energy loss.

[0048] A direction controller 12 is arranged between the iron fixture 10 and the water pumping device 25. The direction controller 12 is in the shape of a circular tube, and the water pumping device 25 is in the shape of a cone. A water pump 21 is arranged at the center of the circular tube-shaped direction controller 12. The water pump 21 is connected to the water pumping pipe 24 and the water storage pipe 29. The water pumping pipe 24 extends straight to the top corner of the conical water pumping device 25. The end of the water pumping pipe 24 is open, and the surroundings are sealed with the edge of the water pumping device 25. The storage water pipe 29 is coiled outside the water pumping pipe 24 and placed in the conical water pumping device 25. The water pump 21 pumps water from the outside through the water pumping pipe 24 and enters the storage water pipe 29 for storage.

[0049] A closed-loop channel 20 is formed between the water pump 21 and the inner wall of the circular tube-shaped part of the direction controller 12. A metal ball 19 is arranged in the closed-loop channel 20. A motor 30 is arranged on the top of the water pump 21. The motor 30 is connected to a connecting rod through a reducer. The metal ball 19 is fixed at the end of the connecting rod. When the motor 30 is working, it drives the metal ball 19 to move in the closed-loop channel 20.

[0050] The water pump 21 can pump water under the action of the battery to change the weight of the direction controller 12, and then change the direction of the direction controller 12 and the device as a whole, that is, control the position of the device underwater and adjust the posture of the device. Pumping water can also change the center of gravity of the entire instrument. Under the combined action of buoyancy and gravity, the instrument automatically moves underwater and can be manually controlled by signals.

[0051] In order to clearly demonstrate this patent, the functions of each component involved in this patent are introduced in turn below:

[0054] Handle ring 3: Can be carried by hand, easy to carry.

[0055] Tail 4: Tail 4 is streamlined and located on one side of water collecting pipe 6, similar to a fish tail, which plays a role in reducing resistance and gliding underwater. Tail is a cuboid with a length of 10 cm, a width of 5 cm and a height of 5 cm, connected to a cylinder with an outer diameter of 10 cm, an inner diameter of 5 cm and a height of 5 cm, and a portion with a central angle of 120°.

[0056] Wing 5: It is streamlined and is located on both sides of the water collecting pipe 6. It is similar to a shark fin and is hollow inside to drain water, thereby reducing resistance and gliding underwater. Wing 5 is composed of two rectangular blocks with a length of 80 cm, a width of 30 cm, and a height of 10 cm, connected to two semi-cylinders with a radius of 15 cm and a height of 10 cm.

[0057] Water collecting pipe 6: used to collect and store water samples. The water collecting pipe is 130 cm high, with an outer diameter of 10 cm and an inner diameter of 8 cm. The inside is hollow and used to store water samples.

[0058] Iron rod 7: Iron rod 7 is used to fix cover 2 and lower iron fixture 10 to prevent water collecting pipe 6 from deformation. It is a solid iron rod with a radius of 2.5 cm and a length of 130 cm. Usually, two are symmetrically arranged outside water collecting pipe 6.

[0059] Positioning signal transmitter 8: Positioning signal transmitter 8 is an electronic transmitter with a GPS positioning system that can transmit signals to GPS. The chip model can be McMurdo SmartFind s20, which has a built-in GPS and 406MHz satellite communication module, and can be automatically activated in deep water and send precise location information.

[0060] Data detector 9: The data detector is an electronic detector that can detect and store data such as water depth, water pressure, water temperature, and water volume. The MY18E20 high-precision temperature sensor chip can be used to measure water temperature, and the MS5837-30BA digital pressure sensor is used to measure water pressure and depth, and is connected to the positioning signal transmitter. The data is transmitted to the GPS satellite through the positioning transmitter.

[0061] Iron fixture 10: There is a water inlet hole 28 in the middle of the iron fixture 10, and the diameter of the water inlet hole 28 is smaller than the diameter of the water collecting pipe 6; the height is 10 cm and the radius is 10 cm.

[0062] Spring rod switch 11: Spring rod switch 11 is used to fix the spring rod and loosen the spring rod when replacing the spring rod. There is a hollow arc pipe inside the spring rod and the connection between the spring rod switch. The spring rod has a corresponding arc solid body inside. Through the up and down movement of the switch, the arc solid body enters the hollow pipe to fix the spring rod to the instrument.

[0063] Direction controller 12: includes metal ball 19, water pump 21, closed loop channel 20. It is in the shape of a circular tube with a radius of 10 cm and a height of 10 cm.

[0064] Motor 13: Motor 13 is used to control the movement of metal ball 19.

[0065] Spring rod 14: On the coaxial outer side of the water collecting pipe 6, springs with different elastic limits can be replaced. Under huge water pressure, the spring rod is used to stabilize the instrument itself to prevent the change of water pressure from causing deformation of the instrument.

[0066] The pressurizing hole 15 is connected to the water collecting pipe 6. By pressurizing, the pressure in the water collecting pipe 6 becomes larger, and the iron sheet 18 is tightly attached to the sealing gasket 16, thereby achieving a sealing effect.

[0067] Sealing gasket 16: on the shoulder 27 of the iron fixture 10, it is in close contact with the iron sheet 18 to seal the water collecting pipe 6.

[0068] Telescopic rod 17: Telescopic rod 17 is used to control whether the iron sheet 18 is opened, and then decide whether to collect water. Normally, the device is put into the water, with one side of the wing having a large weight and facing downward, and the direction controller 12 facing one end. Before launching, the air pressure in the water collecting pipe 6 is consistent with the pressure of the water collecting depth. When the device reaches the water collecting depth, the pressure above and below the iron sheet 18 is basically consistent. According to the real-time information fed back by the data detector 9, when it is confirmed that the device has reached the water collecting depth, a signal is given to the micro motor 30 of the telescopic rod 17. The micro motor 30 drives the telescopic rod 17 to extend, and separates the iron sheet 18 from the sealing gasket 16. At this time, the water collecting pipe 6 is opened, and water enters. The gas in the water collecting pipe 6 naturally floats up and comes out of the water collecting pipe 6.

[0081] The water collection process of the present invention is described below:

[0082] Before launching the equipment:

[0083] Step 1: Calculate the underwater pressure at the sampling point according to the water depth, close the iron sheet 18, and pressurize the water collecting pipe 6 to the underwater pressure at the sampling point;

[0084] Step 2: Fill the wing 5 with water;

[0085] After the equipment is launched:

[0086] Step 3: The device sinks under the action of its own gravity. During the sinking process, the wing side has a large gravity and faces downward, while the water suction device (25) side has a light weight and faces upward;

[0087] Step 4: Before reaching the specified depth, the wing starts to drain water to reduce the gravity of the deep-water automatic water sampling equipment, so that its descent speed is slowed down and it can reach the desired height stably;

[0088] Step 5: When the sampling depth is reached, under the action of the air pressure inside the water collecting pipe 6 and the water pressure outside the water collecting pipe 6, the two sides of the iron sheet 18 are in a force balance state, the telescopic rod 17 pushes the iron sheet 18 to move into the water collecting pipe 6, the iron sheet 18 leaves the sealing gasket 16, and the external water enters the water collecting pipe 6 from the water inlet channel 22. The water collecting pipe 6 starts to collect water samples at the specified depth, and the gas in the water collecting pipe 6 is automatically discharged from the water inlet channel 22 in the form of bubbles upward;

[0089] Step 6: While the water collecting pipe 6 is collecting water, the pressurized drainer 23 discharges the water in the wing 5 to ensure that the deep-water automatic water collection equipment is balanced and can collect water at the specified depth;

[0090] Step 7: The data detector 9 and the positioning signal transmitter 8 obtain water temperature, water pressure, and location information and transmit the signal to the satellite;

[0091] Step 8: When the water collection is completed, the telescopic rod 17 is retracted, and the iron sheet 18 is pressed tightly against the sealing gasket 16 to seal and store the water in the water collection pipe 6;

[0092] Step 9: The wings on both sides continue to drain water, so that the buoyancy of the deep-water automatic water sampling equipment is greater than the gravity, and the deep-water automatic water sampling equipment floats up;

[0093] After the equipment is on land:

[0094] Step 10: The deep-water automatic water sampling equipment floats to the water surface and is recovered.

[0095] Step 12: After the outside of the device is dry, the iron sheet 18 is opened by the micro motor 10 to pour the water sample in the water collecting pipe 6 out from the water inlet channel 22 .

[0096] During underwater sampling, ascent or descent, especially during sampling, the device of the present invention keeps the water suction device 25 in a vertical direction and controls the metal ball so that the water suction device 25 remains horizontal on the horizontal plane, ensuring the consistency of the water sample depth.

[0097] The term “connection” as used in this application may mean a direct connection between components or an indirect connection between components via other components.
