[0017] In order to facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0018] like Figure 1 and Figure 2 As shown, the present invention provides a filtering sampling device for marine environment monitoring, comprising a seawater sampling mechanism 1 for sampling seawater and a solid sampling mechanism 2 for sampling marine solids, wherein a hose assembly 3 for sample extraction and transportation is provided between the seawater sampling mechanism 1 and the solid sampling mechanism 2, and a seawater sampling port 4 is provided on the hose assembly 3; the seawater sampling mechanism 1 comprises a housing 11, wherein the interior of the housing 11 is provided with a pumping assembly 12 for extracting samples, a filter assembly 13 for filtering impurities in the seawater, and a cleaning device for timely cleaning the filter assembly 13. The invention relates to a cleaning vibration mechanism 14 and a plurality of seawater sample bottles 15 for retaining seawater samples; the solid sampling mechanism 2 includes a sampling box 21 and a posture control positioning component 22 for locating the sampling point, the interior of the sampling box 21 is provided with a solid sample cutting component 23 and a solid sample retaining component 24 for storing solid samples, and is also provided with a driving mechanism 25 for driving the solid sampling mechanism 2 to operate; when working, the seawater sampling mechanism 1 is located above the water surface and samples from a shallow depth to a deep depth; the solid sampling mechanism 2 is located below the water surface to cut and sample solid objects in the water.

[0019] In this embodiment, in addition to the seawater sampling mechanism 1, a solid sampling mechanism 2 for seawater is also provided for marine environmental monitoring, realizing the function of sampling solid matter in the ocean, and respectively providing a housing 11 and a sampling box 21, effectively solving the impact damage of seawater pressure on the equipment filter. Among them, the pumping component 12 of the seawater sampling mechanism 1 adopts the existing structure, driven by the motor of the driving mechanism three, and includes a gear pump and a one-way valve. The gear pump pumps water out, and the one-way valve is on the outside of the gear pump, controlling the water to flow only in one direction from the inside of the device to the outside of the device; the seawater sampling mechanism 1 is provided with a cleaning vibration mechanism 14 for cleaning the filter component 13 on the basis of the traditional sampling structure, to prevent the problem of filter hole clogging affecting sampling; the solid sampling mechanism 2 is provided with a driving mechanism four 25 to drive the solid sample cutting component 23 to first cut the solid sample, and then transfer it to the solid sample retaining component 24 for sample retention. This device can effectively solve the impact and damage of seawater pressure on the equipment filter, and can also clean the filter in time. In addition, it has an independent solid sampling function, which can realize efficient and rapid automatic sampling of seawater and solids in seawater.

[0020] The position control and positioning assembly 22 includes a high-definition camera 221, a sensor 222, and a drive mechanism 5 for driving the solid sampling mechanism 2. The drive mechanism 5 includes four motors, each mounted on the vertical frame of the sampling mechanism 21, to control the solid sampling mechanism 2's buoyancy and descent. When the motors rotate forward, the mechanism is subjected to an upward force, causing it to float upward; when the motors rotate reversely, the mechanism is subjected to a downward force, causing it to dive downward. The drive mechanism 5 also includes four motors, each mounted on the bottom of the sampling mechanism 21, to control the direction, forward, backward, and spin of the solid sampling mechanism 2. The control methods for controlling the direction, forward, backward, and spin of the drive mechanism 5, the identification methods for the high-definition camera 221, and the connection with the sensors are all known in the art and will not be detailed here. These eight motors are all servo motors. Operation: The high-definition camera 221 identifies the coral and locates its position. The motors drive the mechanism to the target position and then descend to complete the longitudinal cutting of the sample.

[0021] When sampling seawater, the seawater sampling mechanism 1 of the equipment is positioned at the sampling position, and then the hose assembly 3 is placed at the sampling point. The seawater enters the seawater sampling mechanism 1 from the hose assembly 3, is filtered by the filter assembly 13, and is then introduced into the seawater sample bottle 15 for sample preservation. The cleaning vibration mechanism 14 is started to clean the filter assembly 13, and the pumping assembly 12 empties the hose assembly 3 and the excess seawater entering the mechanism housing 11; the sampling point is changed, and the above operation is repeated to sample seawater. When the sampling point is changed, the seawater sample bottle 15 is replaced at the same time to ensure that the seawater samples at each sampling point are preserved separately.

[0022] When sampling solids in the ocean, taking corals as an example, the corals to be sampled are positioned through the posture control positioning component 22, the solid sampling mechanism 2 is placed above the target position, and then the solid sampling mechanism 2 is controlled to descend, the solid sample cutting component 23 cuts the corals longitudinally, and then the driving mechanism 25 rotates the cutting direction of the solid sample cutting component 23 to cut the corals transversely. After the cutting is completed, the cut sample is transferred to the solid sample retention component 24 for sample preservation, completing the sampling of one sample; then the solid sample cutting component 23 is restored, and the solid sampling mechanism 2 is placed above the next sampling target position, and the above operation is repeated, and the next sample is taken and placed in the new solid sample retention position for preservation.

[0023] like Figure 2 and Figure 3 The cleaning vibration mechanism 14 comprises a rotating shaft 141, a scraper blade 142 for scraping impurities from the filter assembly 13, a vibrating assembly 143, a drive mechanism 144, and a gear train 1 connecting the vibrating assembly 143 and the drive mechanism 144. One end of the rotating shaft 141 passes through the center of the filter assembly 13 and connects to the scraper blade 142. The other end of the rotating shaft 141 is connected to the drive mechanism 144. In this embodiment, the drive mechanism 144 is a stepper motor that drives the rotating shaft 141 to rotate, driving the scraper blade 142. The scraper blades 142 are arranged in a fan-like shape. During rotation, the edges of the scraper blades 142 contact impurities attached to the surface of the filter assembly 13. Simultaneously, the drive mechanism 144 drives the gear train 143 to vibrate. When in contact with the filter assembly 13, the mechanical vibration disrupts the adhesion of the biofilm, preventing micropore blockage caused by algae and shellfish larvae. The scraper blade 142 and the vibrating assembly 143 work together to clean the filter assembly 13, ensuring the proper sampling process.

[0024] like Figure 3As shown, the gear set 1 includes a first driving spur gear 145 coaxially connected to the rotating shaft 141, a first driven spur gear 146 is meshed on the first driving spur gear 145, a first driving bevel gear 147 is coaxially connected to the first driven spur gear 146, and a first driven bevel gear 148 is meshed on the first driving bevel gear 147; a rocker 149 is coaxially connected to the first driven bevel gear 148, and the rocker 149 is hinged to the vibration component 143. In this embodiment, the gear set formed by the first driving spur gear 145, the first driven spur gear 146, the first driving bevel gear 147 and the first driven bevel gear 148 completes the driving operation of the vibration component 143 by the driving mechanism 144. The driving mechanism 144 drives the rotating shaft 141 to rotate, and the rotating shaft 141 drives the first driving spur gear 145 to rotate. The first driving spur gear 145 is engaged with the first driven spur gear 146. The first driven spur gear 146 is coaxial with the first driving bevel gear 147. The first driving bevel gear 147 is engaged with the first driven bevel gear 148. The rocker coaxial with the first driven bevel gear 148 drives the vibration component 143 to move through the hinge structure to vibrate the filter component 13.

The filter assembly 13 includes a filter screen, and a spring is provided on a side of the filter screen near the vibration assembly 143, and the spring elastically abuts against the elastic slider 1432. In this embodiment, the filter holes on the filter screen are large at the upper end and small at the lower end. The vibration rod 1431, driven by the rocker 148, drives the elastic slider 1432, which is made of elastic material. A spring is installed below the filter screen. If the elastic slider 1432 pushes the filter screen once and the spring vibrates three times, the filter screen vibration frequency can reach 100 Hz, meeting the vibration requirements for destroying biofilm attachment.

The float valve 153 is provided at the bottle mouth. When the water level is about to reach the bottle mouth, the valve mouth is closed to complete the sampling. When the equipment reaches the next detection point, the second drive mechanism 152 drives the rotating seat 151 to rotate 30 degrees, and the next seawater sample bottle 15 rotates to the sampling outlet for the next sampling. The second drive mechanism 152 is a stepping motor.

The sampling port 4 is connected to and mounted on the hose 31. In this embodiment, the drive mechanism 33 is a servo motor. During sampling, after the device is positioned at a suitable sampling location, the drive mechanism 33 operates to drive the hose rack 32 to move, thereby lowering the hose 31 to the appropriate depth, allowing the sampling port 4 to align with the sampling point. During sampling, the drive mechanism 33 only needs to be controlled to act on the hose rack 32 to drive the hose 31 to adjust the sampling position and depth.

The output shaft of the drive motor passes through the base plate 2421 and is drivingly connected to the first intermittent gear 251. The first intermittent gear 251 intermittently meshes with the second driven spur gear 233. In this embodiment, the solid sampling tube 231 is hollow and cylindrical and is rotatably connected to the bottom of the sampling box 21 via a bearing. During sampling: Taking coral as an example, the coral to be sampled is positioned through the posture control positioning component 22, the solid sampling mechanism 2 is placed above the target position, the solid sampling tube 231 is aligned with the sampling point, and then the solid sampling mechanism 2 is controlled to descend, and the solid sampling tube 231 cuts the coral longitudinally. Subsequently, the motor is driven to rotate, and the coaxial first intermittent gear 251 rotates until it engages with the second driven spur gear 233, transmitting the power to the second driven spur gear 233, thereby driving the solid sampling tube 231 to rotate, and the cutting knife 232 installed in the solid sampling tube 231 rotates accordingly to complete the transverse cutting direction to cut the coral transversely.
