Description

Technical Field

[0001] This invention relates to the field of navigation radar technology, specifically to a marine navigation radar for marine fishing vessels. Background Technology

[0002] Marine fisheries refer to the production activities of marine fishing and mariculture, and can be divided into near-shore, offshore and deep-sea fisheries according to their distance from the coast.

[0003] In marine fisheries, vessels are indispensable tools for fishing. To ensure the accuracy and safety of navigation, marine navigation radar is usually used on vessels. However, the marine navigation radar currently used on marine fishing vessels still has certain shortcomings:

[0004] Most existing marine navigation radars are fixed to the ship with bolts, which makes installation and disassembly inconvenient and hinders later disassembly, maintenance and replacement. Moreover, the fixed connection method makes it easy for marine fishing vessels to generate a large reaction force when they are violently rocking, which will affect the marine navigation radar and reduce its service life.

[0005] To address the aforementioned problems, the inventors have proposed a marine navigation radar for marine fishing vessels. Summary of the Invention

The first guide rod is fixedly installed at the lower end of the inner cavity of the connecting frame, and the first guide rod is mirror-distributed. The first guide rod is slidably inserted into the first through hole, and symmetrically arranged first springs are movably sleeved on the first guide rod. The two ends of the first springs are fixedly connected to the first sliding plate and the inner wall of the connecting frame, respectively.

[0010] Preferably, the third buffer mechanism includes a fixed support column and a second sliding plate.

A connecting gear is rotatably sleeved on the fixed support column and meshes with a single-sided rack. The second sliding plate is slidably installed at the bottom end of the inner cavity of the connecting base frame and is symmetrically distributed. A T-shaped connecting rod is integrally formed between adjacent second sliding plates, and a double-sided rack is fixedly installed between the two T-shaped connecting rods. The double-sided rack is slidably connected to the bottom inner wall of the connecting base frame and meshes with the connecting gear. Symmetrically arranged second guide rods are fixedly installed on the side walls on both sides of the lower end of the inner cavity of the connecting base frame. A second through hole is opened through the second sliding plate, and the second guide rod is slidably inserted into the second through hole. A second spring is movably sleeved on the second guide rod, and the two ends of the second spring are fixedly connected to the second sliding plate and the inner wall of the connecting base frame, respectively.

[0011] Preferably, the limiting mechanism includes limiting slides.

A third spring is fixedly installed on the opposite sides of both limiting slides, and the opposite ends of the third springs are fixedly connected to the inner wall of the first inner cavity.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. By setting and using the first buffer mechanism, the torque of the reset torsion spring can reduce the reaction force generated on the marine navigation radar body when the marine fishing vessel is violently rocking during navigation, thereby protecting the marine navigation radar body and effectively extending the service life of the marine navigation radar body.

[0014] 2.

In addition, the second spring away from the offset side of the rotating support can be squeezed, and the second spring close to the offset side of the rotating support can be stretched. Thus, the elastic force of the first and second springs can be used to further reduce the reaction force generated on the marine navigation radar body when the marine fishing vessel is violently rocking during navigation, thereby further protecting the marine navigation radar body and effectively extending the service life of the marine navigation radar body.

[0015] 3. The use of the limiting mechanism allows for convenient and quick fixation of the marine navigation radar body, which facilitates user operation and makes it easier to disassemble, repair, and replace later. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1: As Figure 1-8 As shown, the present invention provides a marine navigation radar for marine fishing vessels, including a marine navigation radar body 1 and a connecting base frame 2. A symmetrically arranged connecting side block 21 is fixedly installed at the end of the connecting base frame 2 away from the marine navigation radar body 1, and a connecting through hole 22 is provided through the connecting side block 21. The cooperation between the connecting side block 21 and the connecting through hole 22 facilitates the fixed connection between the connecting base frame 2 and the marine fishing vessel. A first buffer mechanism 3 is slidably installed on the connecting base frame 2, and a second buffer mechanism 4 that cooperates with the first buffer mechanism 3 is provided in the inner cavity of the connecting base frame 2. The second buffer mechanism 4 has a symmetrical structure, and a third buffer mechanism 5 that cooperates with the second buffer mechanism 4 is provided at the bottom of the inner cavity of the connecting base frame 2. A limiting mechanism 6 that cooperates with the marine navigation radar body 1 is provided at the end of the first buffer mechanism 3 away from the connecting base frame 2.

[0028] The first buffer mechanism 3 includes a transverse slide rod 31, which is slidably installed in the inner cavity of the connecting base frame 2. Guide slide rails 35 are fixedly installed on the inner walls of both sides of the connecting base frame 2, and guide sliders 36 are slidably sleeved on the guide slide rails 35. The two ends of the transverse slide rod 31 are fixedly connected to the opposite sides of the two guide sliders 36 respectively. Through the cooperation of the guide slide rails 35 and the guide sliders 36, the movement adjustment of the transverse slide rod 31 is limited and guided. A rotating support column 32 is rotatably sleeved in the middle of the transverse slide rod 31. A connecting slot 23 is opened through the top of the connecting base frame 2, and the rotating support column 32 is movably locked in the connecting slot 23. Symmetrically distributed reset torsion springs 33 are fixedly installed at the end of the rotating support column 32 near the transverse slide rod 31. The reset torsion springs 33 are movably sleeved on the outside of the transverse slide rod 31, and fixed rings 34 are fixedly connected to the opposite ends of the two reset torsion springs 33. The fixed rings 34 are fixedly sleeved on the transverse slide rod 31.

[0029] By adopting the above technical solution, when a marine fishing vessel is sailing on the sea surface and experiences severe shaking, the marine navigation radar body 1 will drive the rotating support 32 to rotate, thereby twisting the two reset torsion springs 33. In turn, the torque of the reset torsion springs 33 can reduce the reaction force generated on the marine navigation radar body 1 when the marine fishing vessel is sailing violently, thus protecting the marine navigation radar body 1 and effectively extending its service life.

[0030] The second buffer mechanism 4 includes a fixed connecting rod 41 and a first guide rod 42. The fixed connecting rod 41 is fixedly installed at the bottom end of the guide slider 36, and a single-sided rack 43 is fixedly installed at the end of the fixed connecting rod 41 away from the guide slider 36. The single-sided rack 43 is slidably connected to the bottom of the inner cavity of the connecting base frame 2, and symmetrically distributed side-connecting columns 44 are fixedly connected to the opposite sides of the two single-sided racks 43. A first sliding plate 45 is fixedly connected to the end of the side-connecting column 44 away from the single-sided rack 43, and a first through hole 46 is opened through the first sliding plate 45. The first guide rod 42 is fixedly installed at the lower end of the inner cavity of the connecting base frame 2, and the first guide rod 42 is mirror-distributed. The first guide rod 42 is slidably inserted into the first through hole 46, and a symmetrically arranged first spring 47 is movably sleeved on the first guide rod 42. The two ends of the first spring 47 are fixedly connected to the first sliding plate 45 and the inner wall of the connecting base frame 2, respectively.

[0031] By adopting the above technical solution, when the rotating support column 32 rotates, the two guide sliders 36 will slide through the transverse slide bar 31, thereby driving the corresponding fixed connecting rod 41 to move, which in turn drives the corresponding single-sided rack 43 to move, thereby driving the two corresponding first slide plates 45 to move through the side connecting column 44, thereby stretching the first spring 47 away from the offset side of the rotating support column 32, and squeezing the first spring 47 close to the offset side of the rotating support column 32.

[0032] The third buffer mechanism 5 includes a fixed support column 51 and a second sliding plate 52. The fixed support column 51 is fixedly installed at the bottom of the inner cavity of the connecting base frame 2, and the fixed support column 51 is symmetrically arranged. A connecting gear 53 is rotatably sleeved on the fixed support column 51, and the connecting gear 53 meshes with a single-sided rack 43. The second sliding plate 52 is slidably installed at the bottom end of the inner cavity of the connecting base frame 2, and the second sliding plates 52 are symmetrically distributed. A T-shaped connecting rod 54 is integrally formed between adjacent second sliding plates 52, and a double-sided connecting rod is fixedly installed between two T-shaped connecting rods 54. The rack 55, with both sides of the rack 55 slidably connected to the inner wall of the bottom end of the connecting base frame 2, and the rack 55 meshes with the connecting gear 53. The side walls on both sides of the lower end of the inner cavity of the connecting base frame 2 are fixedly installed with symmetrically arranged second guide rods 56. The second slide plate 52 has a through hole 57, and the second guide rod 56 is slidably inserted into the second through hole 57. The second guide rod 56 is movably sleeved with a second spring 58, and the two ends of the second spring 58 are fixedly connected to the second slide plate 52 and the inner wall of the connecting base frame 2, respectively.

[0033] By adopting the above technical solution, during use, the single-sided rack 43 will drive the double-sided rack 55 to move in the opposite direction to the moving side of the single-sided rack 43 through the connecting gear 53. This will drive the corresponding second slide plate 52 to move through the T-shaped connecting rod 54, thereby squeezing the second spring 58 away from the offset side of the rotating support 32 and stretching the second spring 58 close to the offset side of the rotating support 32. Thus, the elastic force of the first spring 47 and the second spring 58 can further reduce the reaction force generated on the marine navigation radar body 1 when the marine fishing vessel is violently rocking during navigation, thereby providing further protection for the marine navigation radar body 1 and effectively extending the service life of the marine navigation radar body 1.

[0034] The limiting mechanism 6 includes limiting slide plates 61. A symmetrically distributed first inner cavity 37 is formed inside the end of the rotating support column 32 away from the connecting base frame 2. The limiting slide plates 61 are slidably engaged within the first inner cavity 37. A third spring 62 is fixedly installed on the opposite sides of both limiting slide plates 61, and the opposite ends of the third springs 62 are fixedly connected to the inner wall of the first inner cavity 37. Limiting rods 63 are fixedly connected to the opposite sides of both limiting slide plates 61. A limiting slot 38 is formed at the top center of the rotating support column 32. A limiting block 11 is fixedly installed on the side of the marine navigation radar body 1 near the connecting base frame 2. The limiting block 11 has mirror-distributed limiting holes 12. The limiting block 11 can be slidably inserted into the limiting slot 38. The limiting rod 63 can slide through the limiting slot 38 and slide into the limiting hole 12. The middle of the opposite side of the limiting slide plate 61 is fixedly installed with a traction rope 64, and the traction rope 64 moves through the third spring 62. The top of the rotating support column 32 has a second inner cavity 39 on both sides. The rotating support column 32 and the second inner cavity 39 are rotatably inserted into the rotating support column 32 and the second inner cavity 39. The bottom end of the T-shaped rotating column 65 is fixedly fitted with a winding wheel 66. The winding wheel 66 is rotatably locked in the second inner cavity 39. The end of the traction rope 64 away from the limiting slide plate 61 passes through the second inner cavity 39 and is fixedly connected to the winding wheel 66. The top of the T-shaped rotating column 65 has an array of anti-slip grooves. The anti-slip grooves can increase friction and facilitate operation.

[0035] By adopting the above technical solution, during use, both T-shaped rotating columns 65 can be turned simultaneously, thereby driving the corresponding winding wheel 66 to rotate, which in turn gradually winds up the corresponding traction rope 64. Furthermore, it can drive the two limiting slide plates 61 to move in opposite directions. While the limiting slide plates 61 are moving, they will compress the corresponding third spring 62, and the limiting slide plates 61 can drive the corresponding limiting rods 63 to move, thereby enabling the two limiting rods 63 to move in opposite directions. When the distance between the two limiting rods 63 is adjusted to the maximum, the user can hold the marine navigation radar body 1 and insert the limiting block 11 into the limiting slot 38. When the limiting block 11 is fully inserted into the limiting slot 38, the user can release the two T-shaped rotating columns 65. At this time, the third spring 62 will drive the corresponding limiting slide plate 61 to reset, thereby enabling the two limiting rods 63 to move towards each other through the limiting slide plates 61, and thus enabling the limiting rods 63 to be inserted into the corresponding limiting holes 12, thereby further fixing the marine navigation radar body 1.

[0036] Working principle: In use, the user can fix the connecting base frame 2 to a suitable position on the marine fishing vessel by using the fixing bolts, connecting through holes 22 and connecting side blocks 21. Then, the user can simultaneously turn the two T-shaped rotating columns 65, which can drive the corresponding winding reel 66 to rotate, thereby gradually winding up the corresponding towing rope 64. Furthermore, it can drive the two limiting slide plates 61 to move in opposite directions. While the limiting slide plates 61 are moving, they will compress the corresponding third spring 62, and the limiting slide plates 61 can drive the corresponding limiting rods 63 to move, thereby enabling the two limiting rods to move. When the rod 63 moves in the opposite direction, and the distance between the two limiting rods 63 is adjusted to the maximum, the user can hold the marine navigation radar body 1 and insert the limiting block 11 into the limiting slot 38. When the limiting block 11 is fully inserted into the limiting slot 38, the user can release the two T-shaped rotating columns 65. At this time, the third spring 62 will drive the corresponding limiting slide plate 61 to reset, so that the two limiting rods 63 can move in opposite directions through the limiting slide plate 61, and then the limiting rods 63 can be inserted into the corresponding limiting holes 12, and the marine navigation radar body 1 can be fixed.

[0037] Then the marine navigation radar body 1 can be put into use. During subsequent use, when the marine fishing vessel is sailing on the sea and experiences violent shaking, the marine navigation radar body 1 will drive the rotating support 32 to rotate, thereby twisting the two reset torsion springs 33. In turn, the torque of the reset torsion springs 33 can reduce the reaction force generated on the marine navigation radar body 1 when the marine fishing vessel is sailing violently, thereby protecting the marine navigation radar body 1 and effectively extending the service life of the marine navigation radar body 1.

[0038] Meanwhile, as the rotating support column 32 rotates, it drives the two guide sliders 36 to slide via the transverse slide bar 31, thereby moving the corresponding fixed connecting rod 41, which in turn moves the corresponding single-sided rack 43. This, in turn, moves the two corresponding first sliding plates 45 via the side connecting column 44, thus stretching the first spring 47 away from the offset side of the rotating support column 32 and compressing the first spring 47 close to the offset side of the rotating support column 32. During this period, the single-sided rack 43 will drive the double-sided rack 55 towards the moving side of the single-sided rack 43 via the connecting gear 53. Moving in the opposite direction allows the T-shaped link 54 to drive the corresponding second slide plate 52 to move, thereby compressing the second spring 58 away from the offset side of the rotating support 32 and stretching the second spring 58 close to the offset side of the rotating support 32. This, combined with the elastic force of the first spring 47 and the second spring 58, further reduces the reaction force on the marine navigation radar body 1 when the marine fishing vessel is violently rocking during navigation, thus providing further protection for the marine navigation radar body 1 and effectively extending its service life.

[0039] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
