Description

Technical Field

[0001] This invention relates to the field of underwater sampling, and more particularly to an automatically cleaning ecological planktonic plant and animal sampling device. Background Technology

[0002] As is commonly known, an ecological planktonic sampling device is an underwater device used to collect planktonic plants and animals.

[0003] For example, the authorization announcement number is CN 117419962 B, the authorization announcement date is October 22, 2024, and the title is "A Remotely Controlled Underwater Sampling Device and Sampling Method". It includes a remote controller, a submersible, and a sampling device. The remote controller is wirelessly connected to the submersible. The submersible includes a hull, a submersible chamber, a connecting pipe, and a control device. The tail of the hull is provided with a propulsion chamber. A waterproof motor is fixedly connected inside the propulsion chamber. A propeller is provided on the output shaft of the waterproof motor. A compression cylinder chamber is provided on the front side of the propulsion chamber. A compressed gas cylinder is placed in the compression cylinder chamber.

[0004] As with the above applications, existing underwater sampling devices generally lack cleaning structures. Often, the sampling device is manually cleaned after the collection operation is completed to ensure that subsequent sampling can continue. However, due to the complexity of the underwater environment and the large number of impurities and suspended matter in the water, failure to clean in time can easily affect the sampling. Furthermore, since planktonic plants and animals are prone to moving during sampling, existing sampling devices are prone to inconvenience during sampling. Summary of the Invention

[0005] (I) Purpose of the Invention

[0006] In view of this, the purpose of the present invention is to provide an automatically cleaning ecological planktonic plant and animal sampling device, which can automatically clean the surface of the opening and closing components, thereby achieving immediate cleaning and avoiding affecting the sampling effect. Furthermore, after sampling is completed, no manual cleaning is required, reducing the workload.

[0007] (II) Technical Solution

[0008] To achieve the above-mentioned technical objectives, the present invention provides an automatic cleaning ecological planktonic plant and animal sampling device, which includes a device body mounted above or below an underwater submersible and powered by the underwater submersible. The device body is provided with a sampling chamber.

[0009] An opening and closing assembly, installed within the main body of the device, is used to control the opening and closing of the sampling chamber;

[0010] A cleaning component, which is installed on the outside of the main body of the device, is used to clean the surface of the opening and closing component;

[0011] The cleaning component includes a mounting plate and a brush plate. The mounting plate is located above the sampling chamber. An assembly groove is formed on the inner side of the mounting plate along its length. The brush plate is installed in the assembly groove. A bristle layer is provided on the inner side of the brush plate, and the bristle layer is in contact with the surface of the opening and closing component.

[0012] As a further description of the above technical solution: the opening and closing component includes:

[0013] An external barrier plate is movably installed on the outside of the sampling chamber;

[0014] A connecting bridge is fixedly installed on the top of the outer barrier plate. A lead screw nut is embedded in the center of the connecting bridge, and a lead screw that cooperates with the lead screw nut is sleeved in the lead screw nut.

[0015] A drive motor is installed inside the upper part of the main body of the device, and the output shaft of the drive motor is connected to the top of the lead screw;

[0016] The device body has an outer plate groove and a bridge groove located above the sampling chamber inside, which can accommodate the outer barrier plate and the connecting bridge.

[0017] As a further description of the above technical solution: the main body of the device adopts a cylindrical structure, and the interior of the main body is divided by multiple partition plates arranged in a ring array to form multiple fan-shaped sampling chambers with openings gradually narrowing from the outside to the inside. Each sampling chamber is equipped with an opening and closing component and a cleaning component.

[0018] As a further description of the above technical solution: the main body of the device is provided with a flow guide channel at its center, and a propeller is installed below the flow guide channel;

[0019] The flow channel is equipped with flow guiding mesh holes at the locations of each sampling chamber.

[0020] As a further description of the above technical solution: the opening and closing assembly also includes an inner barrier plate, wherein the top of the inner barrier plate is fixed to one end of the connecting bridge, one side of the inner barrier plate is slidably attached to the inner wall of the sampling chamber where the flow guiding mesh is provided, and the interior of the main body of the device has an inner plate groove that can accommodate the inner barrier plate in the area above the inner barrier plate.

[0021] As a further description of the above technical solution: the cleaning component also includes a fixing plate and an arc-shaped connecting plate, wherein the fixing plate is fixedly installed on the outer surface of the main body of the device, and the mounting plate is fixed on the fixing plate by a plurality of arc-shaped connecting plates. The mounting plate adopts an arc-shaped structure, and the spacing between each position is consistent with that of the outer barrier plate.

[0022] As a further description of the above technical solution: the length of the brush plate is less than the length of the mounting plate, so that there is a gap between the two ends of the brush plate and the inner walls of the two ends of the assembly groove. An elastic component is installed in the gap, so that the brush plate can reciprocate within the assembly groove under external constraints. At least one end of the brush plate is equipped with a push control plate, which extends to the outside of the assembly groove.

[0023] The outer wall of the outer barrier plate is vertically mounted with a side plate at one end of the push control plate. A lateral control component is provided on one side of the push control plate on the side plate. The surface of the main body of the device is provided with a side groove that can accommodate the lateral control component and the side plate. The lateral control component adopts a wave-like structure that undulates continuously in the vertical direction.

[0024] As a further description of the above technical solution: the crests and troughs of the lateral control component both adopt an arc-shaped transition structure, and an auxiliary stop wheel is rotatably installed at the end of the push control plate that contacts the lateral control component. The middle of the auxiliary stop wheel is hollowed out, and one end of the push control plate is rotatably installed in the hollowed-out position of the auxiliary stop wheel through a rotating shaft, so that one end of the push control plate makes rolling contact with the lateral control component through the auxiliary stop wheel.

[0025] As a further description of the above technical solution: push control plates are installed at both ends of the brush plate, and two lateral control components are installed on the outer wall of the outer barrier plate, and the peaks and troughs of the two lateral control components are staggered.

[0026] As a further description of the above technical solution: An adjustment component for adjusting the angle of the device body is installed on the upper part of the device body. The adjustment component includes a main connecting platform. An assembly plate is installed on the top of the main connecting platform for installing the main connecting platform at a preset position on the bottom of the underwater vehicle. A mounting bracket is fixed to the outer edge of the main connecting platform. An adjustment motor is installed on the upper part of the mounting bracket. A drive gear is connected to the output shaft of the adjustment motor. A gear ring is sleeved on the upper outer edge of the device body. The drive gear meshes with the gear ring.

[0027] In the above technical solution, the present invention provides an automatic cleaning ecological planktonic plant and animal sampling device. The device is externally equipped with a cleaning component that can clean the surface of the opening and closing components. This achieves the effect of immediate cleaning and avoids the need for manual cleaning of the opening and closing components after sampling, thus reducing the workload. Moreover, the cleaning component can perform a cleaning once every time the opening and closing components are activated, preventing debris from getting stuck in the opening and closing components and affecting their subsequent use. At the same time, through the design of the cleaning component's structure, the brush used for cleaning does not require an additional drive. It can perform brushing not only in the vertical direction but also in the horizontal direction by relying on its own structure, which is both energy-saving and ensures the cleaning effect.

[0028] By designing the structure of the sampling chamber and the main body of the device, the device can achieve multiple continuous samplings without interference between the sampling chambers. In addition, the designed propeller and flow guide channel make the sampling efficiency higher under the action of water flow. Attached Figure Description

Detailed Implementation

[0041] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure. Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures.

[0042] Example 1

[0043] like Figures 1-10As shown: This embodiment provides a technical solution: an automatic cleaning ecological planktonic plant sampling device, including a device body 1, an opening and closing component 2, and a cleaning component 3. The device body 1 is mounted above or below an underwater submersible and powered by the underwater submersible. The device body 1 has a sampling chamber 102 inside. The opening and closing component 2 is installed inside the device body 1 and is used to control the opening and closing of the sampling chamber 102. The cleaning component 3 is installed outside the device body 1 and is used to clean the surface of the opening and closing component 2. The cleaning component 3 includes a mounting plate 301 and a brush plate 303. The mounting plate 301 is located above the sampling chamber 102. The inner side of the mounting plate 301 has an assembly groove 3010 along the length direction. The brush plate 303 is installed in the assembly groove 3010. The inner side of the brush plate 303 has a bristle layer 3030, which is in contact with the surface of the opening and closing component 2.

[0044] By adopting the above technical solution: When using this device, the main body 1 is first installed above or below the underwater vehicle. The main body 1 moves through the movement control device of the underwater vehicle, and the image acquisition device on the underwater vehicle provides the user with a sampling field of view. When the underwater vehicle moves to the sampling position, the sampling chamber 102 is opened by the opening and closing component 2. After sampling is completed, the sampling chamber 102 is closed by the opening and closing component 2, thus realizing the sampling process. During the opening and closing of the opening and closing component 2, the brush layer 3030 is in contact with the surface of the opening and closing component 2, so the brush layer 3030 can directly clean the surface of the opening and closing component 2. Combined with the underwater environment, the cleaning effect is better. This can avoid the need for manual cleaning of the opening and closing component 2 after sampling, reducing the workload of manual labor. At the same time, this can achieve cleaning every time the opening and closing component 2 is activated, preventing debris from getting stuck in the opening and closing component 2 and affecting its subsequent use.

[0045] Specifically, such as Figures 1-4 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 drive motor 208. 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 in the center of the connecting bridge 203, and a matching lead screw 205 is sleeved in the lead screw nut 204. The drive motor 208 is installed on the... The drive motor 208 is connected to the top of the lead screw 205 inside the main body 1. The main body 1 has an outer plate groove 106 and a bridge groove 105 that can accommodate the outer barrier plate 200 and the connecting bridge 203. When the drive motor 208 runs, it drives the lead screw 205 to rotate. With the cooperation of the lead screw nut 204, the connecting bridge 203 and the outer barrier plate 200 move up and down in the vertical direction, thereby realizing the opening and closing control of the sampling chamber 102.

[0046] Specifically, such as Figures 1-4 As shown, in order to enable the main body 1 of the device to perform multiple continuous samplings without interference between the sampling chambers 102 during the sampling process, in this embodiment, the main body 1 of the device adopts a cylindrical structure. The interior of the main body 1 is divided by multiple partition plates 6 arranged in a ring array to form multiple fan-shaped sampling chambers 102 with openings gradually narrowing from the outside to the inside. Each sampling chamber 102 is equipped with an opening and closing component 2 and a cleaning component 3. This structural arrangement makes the multiple sampling chambers 102 in the device independent of each other. During sampling, the corresponding sampling chamber 102 can be controlled to perform independent sampling, thereby realizing multiple continuous samplings without interference between the sampling chambers 102. Furthermore, this fan-shaped sampling chamber 102 structure design makes the opening of the sampling chamber 102 larger, thus making sampling more convenient.

[0047] Specifically, such as Figures 2-3 As shown, in order to perform sampling operations more quickly, in this embodiment, the device body 1 is provided with a flow channel 100 at the center, and a propeller 101 is installed below the flow channel 100.

[0048] The flow channel 100 has flow guide mesh holes 103 at the locations of each sampling chamber 102. Therefore, when sampling is carried out, the propeller 101 is opened to allow water to flow from the outside of the sampling chamber 102 into the sampling chamber 102 under the action of the propeller 101. The water then enters the flow guide channel 100 through the flow guide mesh holes 103 and is then sprayed out from the flow guide channel 100. This allows the sampling chamber 102 to generate a "suction" when it is open for sampling, which "sucks" the ecological planktonic plants and animals into the sampling chamber 102, achieving the effect of rapid sampling.

[0049] Specifically, such as Figures 3-5 and Figure 7 As shown, in order to avoid mutual interference between sampling chambers 102 during the sampling process, in this embodiment, the opening and closing component 2 also includes an inner baffle plate 201. The top of the inner baffle plate 201 is fixed to one end of the connecting bridge 203, and one side of the inner baffle plate 201 slides against the inner wall of the sampling chamber 102 where the flow guiding mesh 103 is provided. The inner plate groove 107 that can accommodate the inner baffle plate 201 is provided in the area above the inner baffle plate 201 inside the main body 1 of the device.

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

[0051] Example 2

[0052] like Figures 1-3 and Figures 8-9 As shown, this embodiment provides a technical solution: Based on embodiment 1, in order to realize the installation of the cleaning component 3, in this embodiment, the cleaning component 3 further includes a fixing plate 300 and an arc-shaped connecting plate 302. The fixing plate 300 is fixedly installed on the outer surface of the device body 1, and the mounting plate 301 is fixed on the fixing plate 300 by multiple arc-shaped connecting plates 302. The mounting plate 301 adopts an arc-shaped structure, and the spacing between each position is consistent with that of the outer barrier plate 200.

[0053] Specifically, such as Figure 3 As shown, in order to make the inner barrier plate 201 and the outer barrier 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 barrier plate 201 and the outer barrier plate 200. The guide grooves 600 limit the movement of the inner barrier plate 201 and the outer barrier plate 200 to make the movement more stable.

[0054] Specifically, such as Figures 4-5 and Figures 8-10 As shown, in order to improve the cleaning efficiency and effect of the cleaning component 3 on the external barrier plate 200 without the need for additional drive 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 mounting groove 3010. An elastic component 3011 is installed in the gap, so that the brush plate 303 can reciprocate within the mounting groove 3010 under external constraints. At least one end of the brush plate 303 is equipped with a push control plate 3032, which extends to the outside of the mounting groove 3010.

[0055] The outer wall of the outer barrier plate 200 is vertically mounted with a side plate 206 at one end of the push control plate 3032. A horizontal control component 207 is provided on the side plate 206 on one side of the push control plate 3032. A side groove 104 is provided on the surface of the main body 1 of the device to accommodate the horizontal control component 207 and the side plate 206. The horizontal control component 207 adopts a wave-like structure that undulates continuously in the vertical direction.

[0056] By adopting the above technical solution: when the outer barrier plate 200 moves in the vertical direction, since one end of the push control plate 3032 is always pressed against the transverse control member 207, when one end of the push control plate 3032 moves from the trough position of the transverse control member 207 to the crest position, the push control plate 3032 will be pushed and move away from the transverse control member 207. Conversely, when one end of the push control plate 3032 moves from the crest position of the transverse control member 207 to the trough position, the push control plate 3032 will be pushed by the elastic member 3. Under the elastic force of 011, it moves towards the direction of the horizontal control component 207. Since the horizontal control component 207 adopts a continuous undulating wave-like structure, when the outer baffle 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. In conjunction with the up and down movement of the outer baffle plate 200, it realizes the common brushing in the horizontal and vertical directions, which improves the cleaning effect of the device. Specifically, the elastic component 3011 adopts a spring or other structural component that can provide elastic force to the brush plate 303.

[0057] Specifically, such as Figures 8-10 As shown, in order to prevent the push control plate 3032 from getting stuck in the trough structure of the transverse control member 207 and affecting the movement and cleaning of the outer barrier plate 200, in this embodiment, both the crests and troughs of the transverse control member 207 adopt an arc-shaped transition structure. Furthermore, an auxiliary stop wheel 3031 is rotatably installed at the end of the push control plate 3032 that contacts the transverse control member 207. The middle part 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 rolls in contact with the transverse control member 207 through the auxiliary stop wheel 3031. This can prevent the push control plate 3032 from getting stuck.

[0058] Specifically, such as Figure 4 and Figure 5As shown, in order to ensure that the brush plate 303 is subjected to balanced force during lateral movement and to improve the stability and service life of the cleaning component 3 during cleaning, in this 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. This structural arrangement allows the two push control plates 3032 to jointly provide lateral movement force to the brush plate 303, thereby making the force more balanced during movement. Furthermore, the crests and troughs of the two lateral control members 207 are staggered, so that the control movement directions of the two push control plates 3032 are opposite. That is, one end of one push control plate 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 limit position on the trough side, and vice versa.

[0059] Specifically, such as Figures 1-3 As shown, to facilitate the control of the orientation and angle of the main body 1 of the device (relying entirely on the underwater vehicle places high energy demands on it, and large-angle rotation of the underwater vehicle can easily affect water flow, which is not conducive to sampling), in this embodiment, an adjustment component 5 for adjusting the angle of the main body 1 is installed on top of the main body 1. The adjustment component 5 includes a main connecting platform 500, and an mounting plate 4 is installed on the top of the main connecting platform 500 for installing the main connecting platform 500 at a preset position on the bottom of the underwater vehicle. A mounting bracket 503 is fixed to the outer edge of the main connecting platform 500. An adjustment motor 502 is installed above the mounting bracket 503. A drive gear 504 is connected to the output shaft of the adjustment motor 502. A gear ring 501 is sleeved on the upper outer edge of the main body 1. The drive gear 504 meshes with the gear ring 501. When the adjustment motor 502 runs, it drives the drive gear 504 to rotate. Under the action of the gear ring 501, the main body 1 rotates, thereby realizing the autonomous adjustment of the angle of the main body 1 (i.e., it does not need to be adjusted by rotating the underwater vehicle).

[0060] It should be noted that the energy in this device is supplied by an underwater vehicle.

[0061] The exemplary implementation of the solution proposed in this disclosure has been described in detail above with reference to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
