Description

Technical Field

[0001] The invention relates to the field of ecosystem monitoring, in particular to an underwater monitoring device for seaweed field ecosystems. Background Art Algae plants are mainly distributed in fresh water or sea water. Excessive reproduction of certain species can cause red tides, algal blooms and other phenomena. Therefore, there is an urgent need for a new imaging device suitable for monitoring seaweed field ecosystems. At present, for marine ecosystems, relevant technicians have proposed using underwater imaging devices for monitoring. The Korean patent with patent number KR102652939B1 provides an underwater monitoring device, including an upper frame and a lower frame, wherein the upper frame is equipped with an underwater camera, the camera lens is facing downward, and marine life can pass through the inside of the lower frame, and the camera is used to monitor the status of marine life entering and exiting the lower frame. However, the current underwater monitoring optical imaging device has low clarity. The reasons include: first, the device is impacted by the water flow, which can easily cause the camera device to shake when shooting, resulting in blurred imaging; second, under low light conditions affected by water depth, the signal-to-noise ratio of imaging data is difficult to improve. Summary of the invention

[0002] The purpose of the present invention is to design an underwater monitoring device that can obtain high-quality images underwater, enhance the structural stability of the underwater monitoring device, and improve the clarity of imaging.

[0003] In order to solve the above technical problems, the present invention specifically provides the following technical solutions: An underwater monitoring device for a seaweed field ecosystem includes an image capture component, the main body of the image capture component is a camera device, the camera device is connected to a bracket, the image capture component is placed on a first frame, an anchor rope is connected above the first frame to connect a first float and a second float, the first float is suspended in water, the second float floats on the water surface, a counterweight block is provided between the first float and the second float, and a second frame is provided below the first frame.

[0004] The present invention sets an image capture component on the first frame, and the image capture component is used to obtain the situation of the seaweed field in the water. The housing of the camera device is hinged with the bracket and can be rotated in the bracket to obtain the images of the seaweed field at different heights. The rotation angle of the camera device is controlled by a remote control system. The second frame is set below the first frame so that the first frame and the bottom of the water area form a separation space, avoiding the contact between the bottom of the first frame and the bottom of the water area, and improving the overall stability of the device under the action of continuous water flow. In addition, the first float and the second float and the counterweight are connected above the first frame. The first float is suspended in the water, and the second float floats on the water surface. The second float is used to mark the position range of the first frame and the second frame to avoid the collision of the hull with the first frame and the second frame at the bottom of the water area. The second float can quickly locate the first and second frames through the second float to perform related operations, such as taking the internal image data or recharging the battery. The first float and the counterweight are used to balance the torque of the entire device to prevent the first frame and the second frame from tilting.

[0005] Wherein, a fill light assembly is provided in the first frame, and the fill light assembly includes a first lamp body, and the first lamp body is movably connected to the first rod body. A slide groove is provided on the side wall of the first rod body, and the first lamp body is connected to the slider on the slide groove. The first lamp body is connected to the slider of the first rod body, and the slider can move on the slide groove. The first lamp body moves up and down to realize fill light, and the up and down movement of the first lamp body is controlled by a remote control system. A second rod body is provided in the first rod body, and the lower end of the second rod body is connected to a spring, and the upper end is connected to one end of a third rod body. The side of the third rod body is provided with blades, and the other end is connected to a fourth rod body. The fourth rod body is provided with a sleeve and connected to the second lamp body. Batteries are installed inside the first lamp body and the second lamp body. The first lamp body and the second lamp body can play the effect of fill light and thus improve the image clarity. The first lamp body and the second lamp body can fill light at multiple angles.

[0006] In the present invention, the blade structure is designed to utilize the upward thrust or downward thrust generated by the water flowing through the blades to achieve the up and down displacement of the second rod body, thereby driving the up and down displacement of the second lamp body, that is, the second lamp body can rely on the rotation of the blades under the action of the water flow to adjust the fill light range, thereby improving the underwater visibility and capturing images of the seaweed field in a larger range. It should be noted that the movement range of the second rod body is limited by the bottom spring, that is, the displacement range of the second lamp body is limited. In addition, the above-mentioned scheme in which the first lamp body and the second lamp body can be displaced can reduce the probability of adhesion on the surface of the lamp body, that is, changing the impact angle of the water body on the lamp body to achieve cleaning of the surface of the lamp body.

[0007] Optionally, a tripod is provided outside the first rod body. The device will be impacted by water flow when working underwater, and a tripod is provided to protect the first rod body and the first lamp body and the second lamp body.

[0008] Optionally, a bottom seating component is provided on the outer side of the bottom of the second frame, and the bottom seating component is provided with a base plate connected to the bottom of the second frame, and an elastic unit is provided below the base plate, and there are at least two elastic units. In order to improve the bottom seating stability of the device and the overall stability of the device under the action of continuous water flow, a bottom seating component is provided below the second frame, and the bottom seating component has a base plate connected to the bottom of the second frame, and elastic units that can be extended and retracted are arranged around the bottom surface of the base plate. Each elastic unit of the bottom seating component can be adjusted to extend and retract accordingly according to the surface in contact with it. For the bottom surface of the water bottom in different conditions, the bottom seating component is used to ensure that the entire device is in continuous and effective contact with the bottom of the water bottom, avoiding the existence of contact gaps, which may cause the device to be unstable after touching the bottom, or to be knocked down by the water flow, and other problems.

[0009] Optionally, the main body of the elastic unit is a cylinder, the side wall is a flexible plate, a first limit plate is provided in the middle of the cylinder, a second limit plate is provided at the bottom of the cylinder, and a sphere is placed between the first limit plate and the second limit plate. The elastic element includes a flexible plate that can be stretched and deformed up and down, which can achieve a buffering effect on the bottom of the second frame. When the device is placed in the water area, the bottom seat assembly first contacts the medium at the bottom of the water area. The device moves up and down in the water due to the impact of the water flow. The buffering structure of the bottom seat assembly and the flexible plate can achieve the effect of reducing the impact force received by the device after touching the bottom. An elastic member is provided between adjacent elastic units, and the elastic member is connected to the sphere in the elastic unit through a connecting rod. The elastic member and the connecting rod between the elastic units can transfer the impact force of the future flow to the sphere in the adjacent elastic unit, further consume the force, improve the stability of the bottom seat assembly, and avoid the phenomenon of the device tipping over due to excessive local force on the bottom seat assembly.

[0010] The beneficial effects of the present invention are as follows: the image capture component is equipped with a fill light component, the movable first lamp body and the second lamp body can increase the fill light range, and then the position and angle of the lamp body can be adjusted when capturing images at different angles, thereby improving the clarity of the image; a second frame body is provided below the first frame body, and a bottom support component is provided outside the lower side of the second frame body, which can increase the stability of the device; a first float, a second float and a counterweight block are connected above the first frame body, which can mark the location of the device.

The function of the second float 6 is to mark the position range of the first frame 1 and the second frame 2, so as to avoid the collision of the hull with the first frame 1 and the second frame 2 at the bottom of the water area during navigation. The second float 6 can be used to quickly locate the device for related operations, such as taking the internal image data or charging the battery. The function of the first float 5 and the counterweight 4 is to balance the torque of the device as a whole, so as to prevent the first frame 1 and the second frame 2 from tilting. The housing of the camera device 71 is hinged with the bracket 72, and can be rotated in the bracket 72 to obtain the images of the seaweed field at different heights. The rotation angle of the camera device 71 is controlled by the remote control system.

The bottom surface of the base plate 91 is surrounded by elastic units that can be extended and retracted. Each elastic unit of the bottom seating component 9 can be adjusted to extend and retract accordingly according to the surface in contact with it. For the bottom surface of the water bottom in different conditions, the bottom seating component 9 is used to ensure that the entire device is in continuous and effective contact with the bottom of the water bottom, avoiding the existence of contact gaps, which causes the device to be unstable after touching the bottom and be knocked down by the water flow.

[0024] Optionally, the elastic unit body is a cylinder, the side wall is a flexible plate 92, a first limit plate 96 is provided in the middle of the cylinder, a second limit plate 97 is provided at the bottom of the cylinder, and a sphere 93 is placed between the first limit plate 96 and the second limit plate 97.

The elastic element includes a flexible plate 92 that can be stretched and deformed up and down, which can achieve a buffering effect on the bottom of the second frame 2. When the device is placed in the water area, the bottom-seat component 9 first contacts the medium at the bottom of the water area. The device moves up and down in the water due to the impact of the water flow. The buffer structure of the bottom-seat component 9 and the flexible plate 92 can achieve the effect of reducing the impact force received by the device after touching the bottom. The elastic member 94 and the connecting rod 95 between the elastic units can transfer the impact force of the future flow to the sphere 93 in the adjacent elastic unit, further consume the force, improve the stability of the bottom-seat component 9, and avoid the phenomenon of the device tipping over due to excessive local force on the bottom-seat component 9.

[0025] Example 2 Based on Example 1, a fill light component is further designed to improve the imaging quality: A fill light assembly is provided in the first frame 1, and the fill light assembly includes a first lamp body 82, and the first lamp body 82 is movably connected to the first rod body 81. A slide groove is provided on the side wall of the first rod body 81, and the first lamp body 82 is connected to a slider on the slide groove. The first lamp body 82 is connected to the slider of the first rod body 81, and the slider can move on the slide groove, and the first lamp body 82 moves up and down to realize fill light, and the up and down movement of the first lamp body 82 is controlled by a remote control system.

[0026] Optionally, a tripod 83 is provided outside the first rod body 81. When the device is working underwater, it will be impacted by water flow. In order to protect the first rod body 81 and the first lamp body 82 and the second lamp body 87, the tripod 83 is provided.

[0028] When water flows through the blades 86, it will generate an upward thrust or a downward thrust, realizing the up and down displacement of the second rod body 84, thereby driving the up and down displacement of the second lamp body 87, that is, the second lamp body 87 can rely on the rotation of the blades 86 under the action of the water flow to adjust the fill light range, thereby improving the underwater visibility and capturing images of a larger range of seaweed fields. It should be noted that the movement range of the second rod body 84 is limited by the bottom spring 88, that is, the displacement range of the second lamp body 87 is limited.
