Description

Technical Field

[0001] The utility model relates to the field of fish school detection, in particular to a fish finder. Background Art

[0002] A fish finder is a device used during fishing, whose main function is to find and locate the location of fish in a lake or stream through detection technology.

[0003] There are fish finders that are widely circulated on the market, such as Patent No. ZL202020309332, which is named a fish finder probe. This fish finder is directly thrown into a lake or stream. The fish finder will sink to the bottom of the lake, and the camera device will broadcast the recorded images to the display on the shore in real time.

[0004] The data is transmitted between the fish finder and the display through a transmission line, a wired transmission method. When the fish finder is recovered, it will get stuck with stones, resins or various wastes on the bottom of the water. In the fishing industry, this phenomenon is called bottom hanging.

[0005] In addition, when the fish finder is recovered, friction with the bottom residue will occur, causing damage to the fish finder. Utility Model Content

[0006] In order to solve the above problems, the utility model provides a fish finder which can be separated from the bottom of the lake in a suspended manner. When being recovered, it can avoid the situation of being stuck on the bottom and the bottom residue from scratching the fish finder.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A fish finder includes a body with a built-in camera, characterized in that a buoyancy generating unit is also externally arranged on the body, wherein the buoyancy generating unit is configured to displace the volume of a water body to increase the buoyancy of the fish finder.

[0009] Further, the buoyancy generating unit displaces volume within the water body for the purpose of opening up the shape by introducing air.

[0010] Furthermore, the buoyancy generating unit is an air bag.

[0011] Furthermore, the buoyancy generating unit displaces the volume of the water body by introducing air to displace the water body therein.

[0012] Furthermore, the buoyancy generating unit is a floating seat, which is provided with a second opening and a first opening along the floating direction, the first opening being connected to the gas channel of the air pump through a pipeline, and the first opening is for the water in the floating seat to be discharged or poured in.

[0013] Beneficial effects of the utility model:

[0014] The buoyancy generating unit increases buoyancy by displacing the volume of water. It is a form of behavior control and works in conjunction with an external air pump to achieve the purpose of inflation and displacement. With the additional buoyancy, the fish finder can be completely detached from the bottom of the water, and during recovery, it can avoid getting stuck on the bottom and being worn out by waste.

[0015] In addition, the additional buoyancy enables observation of fish schools in different water layers, making it easier for anglers to choose their fishing method. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Embodiment 1:

[0025] Figure 5 Schematic diagram of a fish finder thrown into water, X is the falling direction of the fish finder, along the falling direction, the fish finder includes an air bag 1, an outer cover 2, a main control 3 (such as Figure 1-3 shown).

[0026] The outer cover 2 has a hollow structure inside and is made of a transparent material, which may be acrylic. A camera 7 (not shown in the figure) is provided inside the outer cover 2. In particular, the camera 7 is a rotating camera 7, which can realize 360° video recording when recording images.

[0027] The main control 3 includes a series of circuit parts for driving and powering the camera 7. Of course, the signal transmission between the main control 3 and the camera 7 must be sealed. In addition, the description of the circuit part is only a basic description of this specific embodiment. The detailed circuit principle is the prior art, so its principle will not be further elaborated.

[0028] The airbag 1 is arranged above the outer cover 2, and has a pipeline extending to the shore. The airbag 1 is inflated or deflated by an air pump through the pipeline.

[0029] It can be seen that the utility model can avoid many problems such as scratches and bottom hanging by floating the airbag 1 to a certain height and then recovering it, and has significantly improved the protection effect, thereby avoiding scratches by waste such as stones during recovery. For example, by floating the airbag 1, fish schools at different depths can be inspected. For anglers, this function can simultaneously meet the preparation stages before bottom fishing (the fish hook is on the bottom of the water) and floating fishing (the fish hook is in the upper / middle / lower-middle layers of the water body).

[0030] It should be noted that the degree of inflation inside the airbag 1 is determined by the air pump. Before the fish finder is thrown out, the airbag 1 as a whole is in a contracted state; when the air inside the airbag 1 is filled with air, the internal air pressure of the airbag 1 is in a saturated state, the buoyancy is greater than or equal to the gravity, and the fish finder floats on the water.

[0031] It should also be noted that the outer cover 2 is a hollow structure inside a cylinder. Therefore, a certain amount of air is filled into the airbag 1 (the buoyancy is still less than the gravity), and the fish finder as a whole is maintained in an upright posture to ensure that the fish finder will not tilt or turn sideways to avoid affecting the camera effect.

[0032] Embodiment 2:

[0033] like Figure 4 , 6 -7, a fish finder, along the falling direction X, the fish finder includes a floating seat 4, an outer cover 2, and a main control 3 in sequence.

[0034] The outer cover 2 is made of a transparent material, which may be acrylic. A camera 7 (not shown) is disposed inside the outer cover 2. In particular, the camera 7 is a rotating camera 7, which can realize 360° video recording when recording images.

[0035] The main control 3 includes a series of circuit parts for driving and powering the camera 7. Of course, the signal transmission between the main control 3 and the camera 7 must be sealed. In addition, the description of the circuit part is only a basic description of this specific embodiment. The detailed circuit principle is the prior art, so its principle will not be further elaborated.

[0036] The floating seat 4 is fixed above the outer cover 2, and the interior of the floating seat 4 is a hollow structure. In addition, direction Y is the floating direction, and the floating seat 4 is sequentially provided with a second opening 41 and a first opening 42 along the floating direction. The first opening 42 is connected to the gas channel of the air pump through a pipeline. After the floating seat 4 falls into the water body, the water body enters the floating seat 4 through the second opening 41. During the floating process, the air pump infuses air into the floating seat 4 to discharge the water body in the floating seat 4, so that the floating seat 4 moves toward the water surface, thereby achieving a floating purpose.

[0037] In fact, the floating seat 4 is made of aluminum alloy. The advantage of using the floating seat 4 is that the floating seat 4 does not need to change its shape. Therefore, the floating seat 4 will not float or sink by tightening along the fold or opening outside, and will not wear out. In short, this embodiment 2 will not have multiple shape changes to cause material fatigue, so it has a longer service life.

[0038] It can be seen that the utility model can avoid many problems such as scratches and bottom hanging by floating the floating seat 4 to a certain height and then recovering it, and has significantly improved the protection effect. For example, by floating the air bag 1, fish schools at different depths can be inspected. For anglers, this function can simultaneously meet the preparation stages before bottom fishing (the fish hook is on the bottom of the water) and floating fishing (the fish hook is in the upper / middle / lower-middle layers of the water body).

[0039] It should be noted that the degree of inflation inside the floating seat 4 is determined by the air pump. When the air inside the floating seat 4 is full, the internal air pressure of the floating seat 4 is in a saturated state. At this time, the buoyancy is greater than or equal to the gravity, and the fish finder floats on the water.

[0040] It should also be noted that the outer cover 2 is a hollow structure inside a cylinder. Therefore, a certain amount of air is filled into the airbag 1 (the buoyancy is still less than the gravity), and the fish finder as a whole is maintained in an upright posture to ensure that the fish finder will not tilt or turn sideways to avoid affecting the camera effect.

[0041] The buoyancy is the force or ability of the fish finder to float upward in the water.

[0042] Figure 8 It is a schematic diagram of the fish finder applied to the fishing rod. The pipe and cable between the fish finder and the display 7 are divided into the first section, the second section, and the third section along the direction Z. At the end of the first section is a handwheel 5, and the pipe and cable are wound around the handwheel 5. At the end of the second section is a valve switch 6 in a pipe for maintaining the air in the buoyancy generating unit. At the end of the third section are the display 7 and the air pump 8.

[0043] In addition, in the second section, the cables are connected in sections, specifically a pair of HDCV I high-definition composite video interfaces 9 that cooperate with each other. It is a high-definition video transmission specification based on coaxial cable. When winding, one section of the cable rotates relative to the other section of the cable.

[0044] Similarly, in the second section, the pipeline is also connected in a split manner, and is connected by a pair of rotating gas joints (not shown in the figure), and one section of the pipeline rotates relative to the other section of the pipeline.

[0045] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
