Description

Technical Field

[0001] The present invention belongs to the technical field of camera brackets, and particularly relates to a camera bracket for photographing the activities of benthic animals. Background Art

[0002] Benthic animals in rivers, lakes, and oceans are an important ecological group in the ecosystem, mainly including oligochaetes, mollusks, and insect larvae, etc. They play roles such as promoting the decomposition of organic matter and accelerating the self-purification process, and are key members in maintaining a healthy ecosystem. In fishery, benthic animals are natural high-quality food for economic aquatic animals such as fish, including Chinese sturgeon, eel, black carp, and river crabs. In water environment monitoring, benthic animals have been used as important indicator organisms for organic pollution and play the role of underwater sentinels.

[0003] Underwater photography is an easy-to-use and intuitive method that can truthfully record the activities of benthic animals and assist scientific research. However, researchers need to invest a large amount of time and effort in extracting the target information in the long-term underwater camera footage. Diving photography has strict requirements for water quality conditions and high shooting costs, and the complex underwater environment poses a greater threat to the personal safety of divers.

[0012] Beneficial effects

[0013] First, in the present invention, the inclination angle and length of the feet of the shooting bracket can be flexibly adjusted according to needs. On the one hand, the shooting field of view of the camera can be flexibly adjusted. On the other hand, it can meet the need for stable support of each foot in different underwater terrains. In addition, the structure of the feet can effectively control the depth of penetration into the bottom sediment of the water, and can persistently stabilize the depth of the feet inserted into the bottom sediment of the water, ensuring the stability of the shooting bracket fixed to the underwater target point, which is beneficial to improving the shooting effect.

[0014] Second, in the present invention, the rotating ball of the shooting platform can rotate freely under the action of gravity, so that the shooting direction of the camera can always be kept vertically downward. Through the automatic adjustment of the rotating ball, the influence of factors such as complex underwater terrain and water flow impact on the verticality of the shooting direction can be effectively avoided, and problems such as the shadow of the shooting target, the imbalance of the image ratio, and the horizontal occlusion of the shooting object caused by inclined shooting in the prior art are solved. In addition, by adjusting the overall weight of the iron sinker ring, the shaking of the shooting bracket caused by the influence of water flow impact can be reduced, and the resonance of the shooting platform caused by the influence of water flow can be reduced, and the problems of image ghosting and blurring caused by the vibration of the shooting bracket are solved.

[0015] Third, in the present invention, lighting brackets are installed on each leg. By irradiating the shooting field of view with a lighting source, the brightness in the shooting field of view can be effectively increased, so that the influence of water turbidity on the shooting clarity can be reduced. In addition, the fixed height, lighting direction and the length extending into the shooting field of view of the lighting bracket can all be flexibly adjusted according to needs, which can more effectively assist in the shooting of the activities of benthic aquatic animals and achieve a more optimized shooting effect.

[0021] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of this application.

[0022] As Figure 1 shown, a shooting bracket for filming the activities of benthic animals includes a towing float ball, a battery basket, a shooting platform, legs and lighting brackets.

[0023] The towing float ball includes a float ball 1, a towing rope 2, and a towing rope connection ring 3. The float ball 1 uses a polyurea material as the outer protective layer and a polyurethane foam material or a plastic foam body as the buffer medium inside. It has greater buoyancy and a longer lifespan. When the shooting bracket is placed at the bottom of the water, the float ball 1 floats on the water surface and is used to find the placement position of the shooting bracket. At the four corner positions of the top of the battery basket, there are respectively towing rope rings 12. The towing ropes 2 are respectively connected to the towing rope rings 12, and the upper ends of the four towing ropes 2 are connected to the towing rope connection ring 3. The towing rope connection ring 3 is connected to the float ball 1 through the towing rope 2. The purpose of connecting 4 towing ropes 2 to the battery basket is to reduce the swing of the bracket when the shooting bracket is put into the water or taken out of the water.

[0024] The battery basket is in an overall cuboid structure, including a basket top plate 4 on the top surface, support rods 5 on the side surfaces, and a basket bottom 7. The battery basket is made of carbon steel material. Carbon steel is the earliest and most widely used material in modern industry, and it has low cost and corrosion resistance. Carbon steel has a carbon content of less than 2.11%. Except for iron, carbon, and limited amounts of silicon, manganese, phosphorus, sulfur and other impurities, it is an iron-carbon alloy without other alloying elements. The lithium battery 6 is placed inside the battery basket, which can not only increase the overall stability of the shooting bracket, but also prevent the lithium battery 6 from entering the shooting range. As Figure 2 shown, the basket bottom 7 includes support bars 701, basket side frames 702, foot connection gears 703, and basket frame braces 704. 7 support bars 701 are arranged side by side and fixed on the basket side frames 702. The diagonals of the basket side frames 702 are connected and reinforced by the basket frame braces 704. At the four corner positions at the bottom of the basket bottom 7, at the connection of the basket side frames 702 and the basket frame braces 704, foot connection gears 703 are fixed along the length direction of the basket frame braces 704. The foot connection gears 703 can not only reinforce the basket bottom 7, but also be used to connect the feet.

[0025] The shooting table is set at the central position of the bottom of the battery basket. As Figure 3As shown in the figure, the shooting platform includes a fixed cover 901, a rotating ball 902, a connecting rod 903, a support ring 904, a shooting platform column 905, a sinker ring 906, a shooting base 907, and a waterproof camera 908. The fixed cover 901 is fixed at the junction of two basket frame braces 704 at the bottom of the battery basket. A cage-like structure is formed by connecting the fixed cover 901 and the support ring 904 circumferentially through the connecting rod 903. The upper end of the shooting platform column 905 is connected to the rotating ball 902. The lower end of the shooting platform column 905 is provided with a threaded screw, and the shooting base 907 is provided with a threaded hole. The shooting platform column 905 and the shooting base 907 are detachably connected through a threaded structure. The camera 908 is fixed at the bottom of the shooting base 907 with the shooting direction facing downwards. The sinker ring 906 is replaceably sleeved on the shooting platform column 905. The number of sinker rings 906 can be selected. The sinker ring 906 is increased or decreased according to the water flow speed to reduce the shaking caused by the water flow and also reduce the resonance of the shooting platform caused by the water flow. The rotating ball 902 is rotatably arranged on the support ring 904. The rotating ball 902 can freely rotate under the action of gravity. Even if the shooting bracket may be inclined after being placed, the shooting platform column 905 can be kept vertically suspended, ensuring that the shooting direction of the camera 908 always remains vertically downward. The camera 908 is an underwater camera with waterproof performance, which can continuously shoot or take timed photos. The shooting data is saved in the memory card.

[0026] Support feet are respectively provided at the four corner positions of the bottom of the battery basket. The support feet are of a structure with adjustable telescopic length and adjustable inclination angle. As Figure 4 shown in the figure, the support feet include two support foot rods 1001, a wire fixing ring 1002, a wire placing ring 1003, a connecting sleeve 1004, a fixing screw 1005, a stop post 1006, and a support foot tip 1007. The length of the support foot rod is 50 cm. The two support foot rods 1001 are connected through the connecting sleeve 1004. The support foot rod 1001 is telescopically inserted into the connecting sleeve 1004 and fastened by the fixing screw 1005. The top of the upper support foot rod 1001 is provided with a card slot matching the support foot connecting gear 703. The support foot connecting gear 703 is embedded in the card slot and is rotatably connected to the top of the support foot. The angle between the support foot and the bottom surface of the basket can be adjusted through the support foot connecting gear 703, so that the range of the four support feet opening can be enlarged or reduced, and the shooting field of view of the camera can be adjusted. There can also be multiple connecting sleeves 1004, which can connect multiple support foot rods 1001. The height of the shooting bracket can be adjusted according to the shooting needs. The middle of the connecting sleeve 1004 is hollow, and the support foot rod 1001 can be inserted into the inside of the connecting sleeve 1004. The height of the shooting bracket can be finely adjusted through the insertion depth.

[0027] The wire fixing ring 1002 and the wire placing ring 1003 are made of rubber and have elasticity. The wire placing ring 1003 is connected to the wire fixing ring 1002. The wire fixing ring 1002 is sleeved on the support leg rod 1001 or the connecting sleeve 1004. The power wire of the illumination source in the light stand is sleeved in the wire placing ring 1003 for fixation. The lower end of the support leg is provided with a support leg tip 1007, and a stop post 1006 is vertically fixed between the support leg tip 1007 and the support leg rod 1001. The stop post 1006 is used to block silt or sediment. It is possible that the bottom quality is soft, and the shooting bracket may sink continuously after being placed on the bottom of the water. The stop post 1006 is used to expand the contact area with the water bottom surface, reduce the pressure on the unit area of the bottom surface, and control the depth of the support leg sinking into the water bottom surface. The support leg tip 1007 is used to fix the shooting bracket. If the bottom quality is hard, the support leg tip 1007 is relatively sharp, and it can have a certain penetration depth after the bracket is placed on the bottom of the water, making the shooting bracket more stable.

[0028] Light stands are respectively installed on each support leg, and the installation quantity of the light stands can be adjusted according to needs. The illumination source 1106 in the light stand is used to irradiate the shooting field of view, which can effectively improve the brightness in the shooting field of view, thereby reducing the influence of water turbidity on the clarity of the camera. As Figure 5 shown, the light stand includes a light stand column sleeve 1101, a fixing sleeve 1102, a rotating connection shaft 1103, a light stand column 1104, a steering ball lamp holder 1105, and an illumination source 1106. The fixing sleeve 1102 is sleeved and connected to the support leg and its fixed position is adjustable, which is used to fix the light stand on the support leg rod 1001. By adjusting the position of the fixing sleeve on the support leg rod, the height of the light stand can be adjusted. The light stand column sleeve 1101 is connected to the rotating connection shaft 1103, and the rotating connection shaft 1103 is rotatably connected to the fixing sleeve 1102, and the angle can be adjusted along the vertical plane of the water bottom, which is used to control the direction of the light stand. The light stand column 1104 is telescopically sleeved inside the light stand column sleeve 1101, and the light stand column 1104 can slide inside the light stand column sleeve 1101 to adjust the extending length of the light stand column 1104 in the shooting field. The steering ball lamp holder 1105 is fixed at the end of the light stand column 1104, and the illumination source 1106 is rotatably installed on the steering ball lamp holder 1105 to adjust the irradiation direction of the light. The illumination source 1106 uses an LED lamp.
