DETAILED DESCRIPTION

[0041] The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, and use. It should be understood that in all of these figures, the same or similar reference numerals indicate the same or similar parts and features. The various drawings only schematically represent the concepts and principles of the embodiments of the present disclosure, and do not necessarily show the specific dimensions and proportions of the various embodiments of the present disclosure. Specific parts in specific drawings may be exaggerated to illustrate the relevant details or structures of the embodiments of the present disclosure.

[0042] Example 1

[0043] like Figure 1-Figure 10As shown: This embodiment provides a technical solution: an automatic cleaning ecological phytoplankton sampling device, comprising a device body 1, an opening and closing component 2 and a cleaning component 3, wherein the device body 1 is loaded above or below an underwater submersible, and is powered by the underwater submersible, a sampling chamber 102 is provided in the device body 1, the opening and closing component 2 is installed in the device body 1, and is used to control the opening and closing of the sampling chamber 102, the cleaning component 3 is installed on the outside of the device body 1, and is used to clean the surface of the opening and closing component 2, the cleaning component 3 comprises a mounting plate 301 and a brush plate 303, the mounting plate 301 is located above the sampling chamber 102, an assembly groove 3010 is provided on the inner side of the mounting plate 301 along the length direction, the brush plate 303 is installed in the assembly groove 3010, a bristle layer 3030 is provided on the inner side of the brush plate 303, and the bristle layer 3030 contacts the surface of the opening and closing component 2;

[0044] By adopting the above technical solution: when the device is in use, first the device body 1 is installed above or below the underwater submersible, the movement of the device body 1 is controlled by the movement of the underwater submersible, and the sampling field of view is provided to the user by the image acquisition device on the underwater submersible. When the underwater submersible moves to the sampling position, the sampling chamber 102 is controlled to open by the opening and closing component 2. When the sampling is completed, the sampling chamber 102 is controlled to close by the opening and closing component 2 to realize the sampling process. During the opening and closing process of the opening and closing component 2, since the brush layer 3030 is in contact with the surface of the opening and closing component 2, the brush layer 3030 can directly clean the surface of the opening and closing component 2, and the cleaning effect is better in the underwater environment. In this way, it can be avoided that after the sampling is completed, the opening and closing component 2 needs to be manually cleaned, thereby reducing the manual workload. At the same time, each time the opening and closing component 2 is moved, it can be cleaned once to avoid debris being stuck in the opening and closing component 2 and affecting its subsequent use effect.

[0045] Specifically, Figure 1-Figure 4 and Figure 6 , Figure 7As shown, in order to realize the opening and closing control of the sampling chamber 102 by the opening and closing component 2, in this embodiment, the opening and closing component 2 includes an outer baffle plate 200, a connecting bridge 203 and a driving motor 208, wherein the outer baffle plate 200 is movably installed on the outside of the sampling chamber 102, the connecting bridge 203 is fixedly installed on the top of the outer baffle plate 200, a lead screw nut 204 is embedded and installed at the center of the connecting bridge 203, a lead screw 205 matching with the lead screw nut 204 is sleeved and installed, and the driving motor 208 is installed on the mounting The output shaft of the driving motor 208 is connected to the top of the lead screw 205, and the interior of the device body 1 is located above the sampling chamber 102, and an outer plate groove 106 and a bridge groove 105 that can accommodate the outer baffle plate 200 and the connecting bridge 203 are provided. When the driving motor 208 is running, it drives the lead screw 205 to rotate, and with the cooperation of the lead screw nut 204, the connecting bridge 203 and the outer baffle plate 200 are lifted and lowered in the vertical direction, thereby realizing the opening and closing control of the sampling chamber 102.

[0046] Specifically, Figure 1-Figure 4 As shown, in order to enable the device body 1 to perform multiple continuous samplings, and during the sampling process, the sampling chambers 102 will not interfere with each other, in this embodiment, the device body 1 as a whole adopts a cylindrical structure, and the interior of the device body 1 is divided by a plurality of partition plates 6 distributed in a ring array, forming a plurality of sampling chambers 102 with fan-shaped structures whose openings gradually narrow from the outside to the inside, and each sampling chamber 102 is correspondingly installed with an opening and closing component 2 and a cleaning component 3. Such a structural arrangement makes the multiple sampling chambers 102 in the device independent of each other, and independent sampling can be performed by controlling the corresponding sampling chamber 102 during sampling, thereby realizing multiple continuous samplings, and during the sampling process, the sampling chambers 102 will not interfere with each other. Furthermore, the fan-shaped sampling chamber 102 structural design makes the opening of the sampling chamber 102 larger, so sampling is more convenient.

[0047] Specifically, Figure 2-Figure 3 As shown, in order to perform sampling operations more quickly, in this embodiment, a guide channel 100 is provided at the center of the device body 1, and a propeller 101 is installed below the guide channel 100;

[0048] Diversion mesh holes 103 are provided inside the diversion channel 100 at the positions of each sampling chamber 102. Therefore, when sampling is performed, the propeller 101 is controlled to open so that water flows from the outside of the sampling chamber 102 into the inside of the sampling chamber 102 under the action of the propeller 101, and then enters the diversion channel 100 through the diversion mesh holes 103, and is then ejected from the diversion channel 100, so that the sampling chamber 102 can generate "suction" when open for sampling, and the ecological phytoplankton is "sucked" into the sampling chamber 102, thereby achieving the effect of rapid sampling.

[0049] Specifically, Figure 3-Figure 5 and Figure 7 As shown, in order to avoid mutual interference between the sampling chambers 102 during the sampling process, in this embodiment, the opening and closing component 2 also includes an internal resistance baffle 201, wherein the top of the internal resistance baffle 201 is fixed to one end of the connecting bridge 203, one side of the internal resistance baffle 201 is slidably fitted with the inner wall of one side of the sampling chamber 102 where the guide mesh 103 is set, and the inner plate groove 107 capable of accommodating the internal resistance baffle 201 is opened in the upper area of ​​the internal resistance baffle 201 inside the device body 1;

[0050] By adopting the above technical solution: during the sampling process, except for opening the sampling chamber 102 to be sampled, the other sampling chambers 102 are not connected to the guide channel 100 under the blocking of the internal blocking plate 201. At this time, the "suction force" generated by the propeller 101 only acts on the sampling chamber 102 to be sampled. This can ensure that the "suction force" is not dispersed during sampling, which is convenient for sampling, and avoid affecting the sampling chamber 102 after the sampling is completed.

[0051] Example 2

[0052] like Figure 1-Figure 3 and Figure 8-Figure 9 As shown, this embodiment provides a technical solution: on the basis of Example 1, in order to realize the installation of the cleaning component 3, in this embodiment, the cleaning component 3 also includes a fixed plate 300 and an arc-shaped connecting plate 302, wherein the fixed plate 300 is fixedly installed on the outer surface of the device body 1, and the mounting plate 301 is fixed on the fixed plate 300 through a plurality of arc-shaped connecting plates 302, and the mounting plate 301 adopts an arc-shaped structure, and each position is consistent with the spacing of the outer barrier plate 200.

[0053] Specifically, Figure 3 As shown, in order to make the inner baffle plate 201 and the outer baffle plate 200 more stable when moving, in this embodiment, the surface of the partition plate 6 is provided with guide grooves 600 at the edge positions of the inner baffle plate 201 and the outer baffle plate 200. Through the limiting of the guide grooves 600, the movement of the inner baffle plate 201 and the outer baffle plate 200 is made more stable.

[0054] Specifically, Figure 4-Figure 5 and Figure 8-Figure 10 As shown, in order to improve the cleaning efficiency and effect of the cleaning assembly 3 on the external baffle plate 200 without the need for additional driving equipment, in this embodiment, the length of the brush plate 303 is less than the length of the mounting plate 301, so that there is a gap between the two ends of the brush plate 303 and the inner walls of the two ends of the assembly groove 3010, and an elastic component 3011 is installed in the gap, so that the brush plate 303 can reciprocate in the assembly groove 3010 under external constraints, and a push control plate 3032 is installed at least at one end of the brush plate 303, and the push control plate 3032 extends to the outside of the assembly groove 3010;

[0055] The outer wall of the outer baffle plate 200 is located at one end of the push control plate 3032 and is provided with a side plate 206 in the vertical direction. A transverse control member 207 is provided on the side of the push control plate 3032 on the side of the side plate 206. A side groove 104 capable of accommodating the transverse control member 207 and the side plate 206 is provided on the surface of the device body 1. The transverse control member 207 adopts a wave-like structure that continuously undulates in the vertical direction.

[0056] By adopting the above technical solution: when the outer baffle plate 200 moves in the vertical direction, since one end of the push control plate 3032 is always pressed on the horizontal control member 207, when one end of the push control plate 3032 moves from the trough position of the horizontal control member 207 to the peak position, the push control plate 3032 will be pushed and move away from the horizontal control member 207. Conversely, when one end of the push control plate 3032 moves from the peak position of the horizontal control member 207 to the trough position, the push control plate 3032 will be pushed and move away from the elastic member 307. Under the action of the elastic force of 011, it moves in the direction close to the horizontal control member 207. Since the horizontal control member 207 adopts a continuously undulating wave-like structure, when the outer blocking plate 200 moves up and down, the push control plate 3032 drives the brush plate 303 to make horizontal reciprocating motion in the assembly groove 3010, and cooperates with the up and down movement of the outer blocking plate 200 to achieve horizontal and vertical brushing, thereby improving the cleaning effect of the device. Specifically, the elastic component 3011 adopts a spring or other structural member that can provide elastic force to the brush plate 303.

[0057] Specifically, Figure 8-Figure 10 As shown, in order to allow the push control plate 3032 to get stuck in the trough structure of the transverse control member 207 and affect the movement and cleaning of the outer blocking plate 200, in this embodiment, the crests and troughs of the transverse control member 207 both adopt an arc-shaped transition structure, and the end of the push control plate 3032 that contacts the transverse control member 207 is rotatably installed with an auxiliary stop wheel 3031, wherein the middle portion of the auxiliary stop wheel 3031 is hollowed out, and one end of the push control plate 3032 is rotatably installed in the hollow position of the auxiliary stop wheel 3031 through a rotating shaft, so that one end of the push control plate 3032 is in rolling contact with the transverse control member 207 through the auxiliary stop wheel 3031, thereby avoiding the push control plate 3032 from getting stuck.

[0058] Specifically, Figure 4 and Figure 5As shown, in order to make the brush plate 303 be subjected to balanced force when it moves laterally and to improve the stability and service life of the cleaning component 3 during cleaning, in the present embodiment, push control plates 3032 are installed at both ends of the brush plate 303, and two lateral control members 207 are correspondingly installed on the outer wall of the outer barrier plate 200. Such a structural arrangement enables the two push control plates 3032 to jointly provide a lateral movement force to the brush plate 303, so that the force is more balanced when it moves, and the crests and troughs of the two lateral control members 207 are staggered from each other, so that the controlled movement directions of the two push control plates 3032 are opposite, that is, one end of one of the push control plates 3032 is located in the trough, and one end of the other push control plate 3032 is located on the crest. At this time, the brush plate 303 moves to the extreme position on the trough side, and vice versa.

[0059] Specifically, Figure 1-Figure 3 As shown, in order to facilitate the control of the direction angle of the device body 1 (complete reliance on the underwater submersible requires a large amount of energy consumption for the underwater submersible, and if the underwater submersible is rotated and moved at a large angle, it is easy to affect the flow of the water body, which is not conducive to sampling), in this embodiment, an adjustment component 5 for adjusting the angle of the device body 1 is installed above the device body 1, and the adjustment component 5 includes a main connection platform 500, and an assembly plate 4 is installed on the top of the main connection platform 500, which is used to install the main connection platform 500 at a preset position at the bottom of the underwater submersible. A mounting frame 503 is fixed to the outer edge of the main connecting platform 500, and an adjusting motor 502 is installed above the mounting frame 503. A driving gear 504 is connected to the output shaft of the adjusting motor 502. A gear ring 501 is sleeved and installed on the upper outer edge of the device body 1, and the driving gear 504 is meshed with the gear ring 501. When the adjusting motor 502 is running, it drives the driving gear 504 to rotate. With the cooperation of the gear ring 501, the device body 1 rotates, thereby realizing autonomous adjustment of the angle of the device body 1 (i.e., no rotation adjustment through the underwater submersible is required).

[0060] It should be noted that the energy in this device is provided by underwater vehicles.
