Description

Technical Field

[0001] This invention relates to the field of marine sediment content observation, specifically to a collection device for measuring marine sediment content. Background Technology

[0002] Marine sediment concentration collection devices are specialized equipment used to measure the suspended sediment content in oceans or water bodies. They are widely used in marine environmental monitoring, estuary management, water conservancy projects, and ecological research. Sediment concentration observation is a very important observation project in the field of marine observation. In-situ sediment concentration observation typically involves lowering measuring instruments such as OBS and RBR, or seawater samplers, to the target depth in the sea using winches and cables fixed to the observation vessel to measure the sediment concentration.

[0003] In existing technologies, when collecting samples to measure marine sediment content at fixed points or estuaries, the downward-thrown sampling device deviates due to the impact of water flow, resulting in inaccurate sampling locations. This is especially true when sampling multiple points along a section of an estuary, where the sampling location deviates with the impact of water flow, affecting the collection results. Summary of the Invention

[0004] The problem to be solved by the present invention is to provide a collection device for measuring the sediment content of the ocean, which overcomes the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a collection device for measuring marine sediment content, comprising two parallel walking ropes, a truss, a first drive mechanism, a second drive mechanism, a lifting mechanism, a correction mechanism, and a collection tube mechanism. The first drive mechanism and the second drive mechanism are respectively fixed at both ends of the truss, and each of the first drive mechanism and the second drive mechanism corresponds to one of the walking ropes. Both the first drive mechanism and the second drive mechanism can move along the direction of the walking rope. The lifting mechanism is fixed at the bottom of the first drive mechanism, and the lower end of the lifting rope in the lifting mechanism is connected to the collection tube mechanism. The collection tube in the collection tube mechanism is horizontally suspended below the lifting rope. The correction mechanism is fixed at the bottom of the second drive mechanism. The correction mechanism includes a correction rope, a correction roller, and a correction motor. The correction rope is wound around the correction roller, the output end of the correction motor is connected to the rotating shaft of the correction roller, and the end of the correction rope is connected to the collection tube mechanism.

[0006] Optionally, it also includes a guide rail, a slider, and a calibration rope. One end of the guide rail is fixed to one end of the truss with a second drive mechanism. The slider cooperates with and slides with the guide rail. Two vertical guide rods are spaced apart on the top of the slider. The calibration rope passes between the two guide rods and is in the same direction as the walking rope. A lateral distance sensor is provided on the guide rail near one end of the truss.

[0007] Optionally, a longitudinal distance sensor is provided on the truss.

[0008] Optionally, the bottom of the first drive mechanism is further provided with an actuation mechanism, which includes an actuation roller, an actuation motor, and an actuation rope. The output end of the actuation motor is connected to the rotating shaft of the actuation roller, and the actuation rope is wound around the actuation roller. The collection tube mechanism also includes a polygonal guide rod and an inverted U-shaped shield. The polygonal guide rod passes through a polygonal hole on the shield and is slidably connected to the shield. The lower end of the polygonal guide rod is fixed to the collection tube, and the upper end is connected to the lifting rope. The two ends of the collection tube are slidably connected to the inner side of the shield. The bottom of the first drive mechanism has a guide frame with a horizontal plate having a guide hole. The lifting rope and the actuation rope both pass through the guide hole, and the end of the actuation rope is connected to the shield.

[0009] Optionally, a deflection plate is provided at the tail end of the collection tube, and a counterweight is provided at the bottom of the collection tube.

[0010] Optionally, the lifting mechanism further includes a lifting motor and a lifting roller, the output end of the lifting motor is connected to the rotating shaft of the lifting roller, and the lifting rope is wound around the lifting roller.

[0011] Optionally, the first driving mechanism and the second driving mechanism have the same structure. The second driving mechanism includes a driving frame and a driving motor. The driving frame includes two spaced-apart mounting plates. The walking rope can pass between the two mounting plates. There is a driving wheel and two driven wheels between the two mounting plates. The driving wheel and the driven wheels are arranged in a triangular structure. The driven wheels are located below the walking rope, and the driving wheels are located above the walking rope. The driving motor is connected to the shaft of the driving wheel.

[0012] The advantages and positive effects of this invention are as follows: due to the adoption of the above technical solution, the structure is reasonably designed, the correction mechanism ensures that the collection tube on the lifting mechanism does not slip, and the data collected by the sensor offsets the calculation error caused by the water flow impact, thereby improving the measurement accuracy of sand content.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention through specific circumstances.

[0019] As shown in the figure, this invention provides a collection device for measuring marine sediment content, including two parallel walking ropes 16, a truss 1, a first drive mechanism, a second drive mechanism, a lifting mechanism, a correction mechanism, and a collection tube mechanism. The first and second drive mechanisms are respectively fixed to both ends of the truss 1, and each corresponds to one walking rope 16. The first and second drive mechanisms have the same structure. Taking the second drive mechanism as an example, it includes a drive frame 17 with two spaced mounting plates and a drive motor 20. The walking rope 16 can pass between the two mounting plates. Between the two mounting plates are a drive wheel 19 and two driven wheels 18, which are arranged in a triangular pattern. The driven wheels 18 are located below the walking rope 16, and the drive wheels 19 are located above the walking rope 16. The drive motor 20 is connected to the shaft of the drive wheel 19. The first and second drive mechanisms... All drive mechanisms can move along the direction of the walking rope 16 under the drive of the drive motor 20. The lifting mechanism is fixed at the bottom of the first drive mechanism. The lifting mechanism includes a lifting rope 8, a lifting motor 21, and a lifting roller 22. The output end of the lifting motor 21 is connected to the rotating shaft of the lifting roller 22. The lifting rope 8 is wound around the lifting roller. The lifting motor 21 drives the lifting roller 22 to rotate, thereby pulling the lifting rope 8 to move. The lower end of the lifting rope 8 is connected to the collection tube mechanism. The collection tube 10 in the collection tube mechanism is horizontally suspended below the lifting rope 8. The correction mechanism is fixed at the bottom of the second drive mechanism. The correction mechanism includes a correction rope 15, a correction roller 24, and a correction motor 23. The correction rope 15 is wound around the correction roller 24. The output end of the correction motor 23 is connected to the rotating shaft of the correction roller 24. The end of the correction rope 15 is connected to the collection tube mechanism. The correction motor 23 drives the correction roller 24 to rotate, thereby pulling the correction rope 15 to move.

[0020] In use, the two ends of the walking rope 16 are fixed to the two banks or two moving platforms. The truss 1 is driven to move along the walking rope 16 by two drive mechanisms. When it moves to the sampling position, the lifting roller 22 rotates to drive the lifting rope 8, which in turn drives the collection tube mechanism to descend to the predetermined depth. At the same time, the correction motor 23 drives the correction roller 24 to rotate, causing the correction rope 15 to extend synchronously. Under the traction of the correction rope 15, the impact and deviation of the water flow are offset, and the collection tube mechanism samples the water.

[0021] The bottom of the first drive mechanism is also equipped with an action mechanism that cooperates with the collection tube mechanism. The action mechanism includes an action roller 26, an action motor 25, and an action rope 14. The output end of the action motor 25 is connected to the rotating shaft of the action roller 26. The action rope 14 is wound around the action roller 26. The action motor 25 drives the action roller 26 to rotate, and the rotation of the action roller 26 drives the action rope 14 to move. The collection tube mechanism includes a collection tube 10, a polygonal guide rod 9, and an inverted U-shaped shield 13. The polygonal guide rod 9 passes through the shield 13. The polygonal hole is slidably connected to the shield 13. The lower end of the polygonal guide rod 9 is fixed to the collection tube 10, and the upper end is connected to the lifting rope 8. Both ends of the collection tube 10 are slidably connected to the inner side of the shield 13. The bottom of the first drive mechanism has a guide frame 27, and the guide frame 27 has a horizontal plate with a guide hole. The lifting rope 8 and the action rope 14 both pass through the guide hole. The end of the action rope 14 is connected to the shield 13. The tail of the collection tube 10 is provided with a deflection plate 12, and the bottom of the collection tube 10 is provided with a counterweight 11.

[0022] When the collection tube 10 is lowered to the designated height, the actuating motor 25 drives the actuating rope 14 to pull the shield 13 upward on the polygonal guide rod 9, so that the water can flow into the collection tube 10. Under the action of the deflection plate 12, the collection tube 10 is oriented towards the direction of water flow, and under the action of the counterweight 11, the collection tube 10 is kept horizontal, which facilitates the entry of water. After the collection is completed, the actuating motor 25 moves in the opposite direction, and the shield 13 shields both sides of the collection tube 10 under the action of gravity, thus realizing sampling.

[0023] To further eliminate the calculation error of sand content in the collected samples, a guide rail 3, a slider 4, and a calibration rope 6 are also provided in the above structure. One end of the guide rail 3 is fixed to the end of the truss 1 with the second drive mechanism. The slider 4 cooperates with the guide rail 3 and is slidably connected to the guide rail 3. Two vertical guide rods 5 are arranged at intervals on the top of the slider 4. The calibration rope 6 passes between the two guide rods 5. The calibration rope 6 is in the same direction as the walking rope 16. A lateral distance sensor 7 is provided on the guide rail 3 near the end of the truss 1. The two ends of the calibration rope 6 are fixed to the banks or two moving platforms respectively. During the water sample collection process, the calibration rope 6 does not bend and is not pulled by the water, which is equivalent to a standard rope. Due to the impact of the water flow, the action rope 14 and the walking rope 16 will deviate. The walking rope 16 will pull the guide rail 3 to move. At this time, the sensor 7 can measure the lateral movement of the slider 4 along the calibration rope 6, thereby obtaining the deflection of the slider 4, which is convenient to offset the lateral deviation of the action rope 14 caused by the impact of the water flow. A longitudinal distance sensor 2 is set on the truss 1. The longitudinal distance sensor 2 is used to collect the height information above the water surface, which offsets the sag of the walking rope 16 and thus increases the sampling position accuracy.

[0024] All electrical components in this case should be connected to their compatible power supplies via wires. Appropriate controllers should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described above, which outlines the sequential operation of each electrical component to complete the electrical connection. The detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, without further explanation of electrical control.

[0025] The embodiments of the present invention have been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
