[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0027] Reference Figures 1 to 5 As shown, a sonar detector lifting device includes a support plate 1, and four support legs 2 are fixedly installed on the bottom of the support plate 1;

[0028] It also includes: a lifting mechanism for controlling the lifting and lowering of the sonar detector;

[0029] A rack 51 is slidably installed on the top of the support plate 1, and one end of the rack 51 is rotatably connected to the first connecting plate 54. Second connecting plates 55 are rotatably installed on both sides of the first connecting plate 54. The top of the second connecting plate 55 is rotatably connected to the lifting rod 62. The top of the lifting rod 62 is slidably connected to the connecting wire 64. One end of the connecting wire 64 is fixedly connected to the descending frame 81, and the other end of the connecting wire 64 is wound around and connected to the winding shaft 652.

[0030] During the use of the sonar detector, the sonar detector needs to enter deep water for detection, so a device is needed to control the rise and fall of the sonar detector.

[0031] During use, the rack 51 first slides and causes the first connecting plate 54 to rotate, and the first connecting plate 54 rotates with the second connecting plate 55. The angle between the second connecting plate 55 and the first connecting plate 54 becomes smaller, and the lifting rod 62 rises. At this time, the support plate 1 is pushed to push the descending frame 81 to the water surface, and the connecting line 64 is released. Due to gravity, the lifting frame 81 will fall toward the water surface and rise into the water with the sonar detector.

[0032] Further, such as Figure 2 As shown, a counterweight box 3 is fixedly mounted on one side of the top of the support plate 1 , and a 32 is movably mounted in the inner cavity of the counterweight box 3 .

[0033] In order to prevent the sonar detector lifting device from tipping over due to uneven force when the lifting frame 81 falls, a counterweight 31 is installed at the other end of the support plate 1 to ensure the stability of the sonar detector lifting device.

[0034] Further, such as Figure 2 As shown, the support plate 1 is fixedly installed with two first motors 41, the output shaft of the first motor 41 is fixedly connected with a threaded rod 42, the outer surface of the threaded rod 42 is threadedly connected with a cross plate 43, and two first grooves 44 are provided on the top of the cross plate 43. The inner surfaces of the two first grooves 44 are slidably installed with limit rods 45, and the other ends of the two limit rods 45 are fixedly installed on the bottom of the support plate 1. Two rubber blocks 46 are fixedly installed on the bottom of the cross plate 43.

[0035] In order to keep the sonar detector lifting device fixed when the descending frame 81 is lowered into the water, during use, the first motor 41 rotates the threaded rod 42, and the threaded rod 42 cooperates with the two limit rods 45 to make the cross plate 43 move up and down. When the sonar detector lifting device needs to be fixed, as long as the first motor 41 rotates, the two rubber blocks 46 are close to the ground to ensure that the sonar detector lifting device will not move.

[0036] Further, such as Figure 2 As shown, a slide groove 11 is provided on the top of the support plate 1, and the rack 51 is slidably installed on the inner surface of the slide groove 11. A second motor 52 is fixedly installed on the top of the support plate 1, and the output shaft of the second motor 52 is fixedly connected to a gear 53, and the gear 53 and the rack 51 are engaged with each other.

[0037] When the lifting frame 81 needs to be lowered into the water, the second motor 52 drives the gear 53 to rotate, the gear 53 engages with the rack 51, and the rack 51 slides on the inner surface of the slide groove 11 to drive the first connecting plate 54 to rotate.

[0038] Further, such as Figure 2 As shown, two first fixed blocks 61 are fixedly installed on the top of the support plate 1, and the two first fixed blocks 61 are rotatably installed on the outer surface of the lifting rod 62. A number of wire fixing rings 63 are fixedly installed on the top of the lifting rod 62. A fixed plate 65 is fixedly installed on one side of the first fixed block 61. The winding shaft 652 is rotatably installed between the two fixed plates 65. A third motor 651 is fixedly installed on one side of the fixed plate 65. The output shaft of the third motor 651 is fixedly connected to one end of the winding shaft 652.

[0039] In order to make the lifting frame 81 descend a greater distance, the third motor 651 drives the winding shaft 652 to rotate, and the winding shaft 652 can tighten the connecting line 64 or release more connecting line 64. The upper gold-searching connecting line 64 can pull out the lifting frame 81 that is deep in the water. Loosening the connecting line 64 can enable the lifting frame 81 to descend into deeper water.

[0040] Further, such as Figure 3 As shown, two base plates 71 are fixedly installed on the top of the support plate 1. The two base plates 71 are respectively located on both sides of the slide groove 11. A first damper 72 is fixedly installed on the top of the base plate 71. A guard plate 73 is fixedly connected to the top of the first damper 72.

[0041] After the lifting frame 81 is retracted, when the sonar detector lifting device is moved, in order to avoid damage to the components in the lifting frame 81 due to bumps, it is necessary to protect the detection components in the lifting frame 81 by shock absorption. After the lifting frame 81 is retracted, the bottom of the second connecting plate 55 is located at the top of the guard plate 73. When encountering bumps, the first damper 72 is used to absorb shock for the second connecting plate 55, thereby reducing the bump amplitude of the lifting frame 81, thereby achieving the purpose of protecting the detection components in the lifting frame 81.

[0042] Further, such as Figure 4 and Figure 5 As shown, four third grooves 82 are formed on the top wall of the descending frame 81, a fourth motor 83 is fixedly connected to the top wall of the inner surface of the descending frame 81, the output shaft of the fourth motor 83 is fixedly connected to the fifth motor 831, the output shaft of the fifth motor 831 is fixedly connected to the propeller 832, four second dampers 84 are fixedly installed on the bottom of the support plate 1, and one end of the second damper 84 is fixedly connected to a pad 841;

[0043] A second groove 811 is provided on the bottom wall of the descending frame 81, and an electric telescopic rod 85 is fixedly installed on the inner surface of the second groove 811. One end of the electric telescopic rod 85 is fixedly connected to a slider 851, and the slider 851 is slidably installed on the inner surface of the second groove 811. The top of the slider 851 is rotatably connected to a third connecting plate 852, and a second fixed block 853 is fixedly installed on the top of the support plate 1. The second fixed block 853 is rotatably connected to a fourth connecting plate 854, and one end of the third connecting plate 852 and the fourth connecting plate 854 are jointly rotatably connected to a sonar detector 855.

[0044] In order to facilitate the adjustment of the detection direction of the sonar detector 855 in the water, the fourth motor 83 drives the fifth motor 831 and the propeller 832 to change direction. The fifth motor 831 rotates with the propeller 832 to drive the lifting frame 81 to move in the water, thereby increasing the detection range of the sonar detector 855. When different angles need to be detected, the electric telescopic rod 85 is extended or contracted to make the slider 851 slide on the inner surface of the second groove 811, which can rotate the third connecting plate 852 and the fourth connecting plate 854, thereby achieving the purpose of adjusting the detection angle of the sonar detector 855. When the lifting frame 81 needs to be lowered to the bottom of the water, in order to avoid the lifting frame 81 hitting stones when it contacts the bottom of the water and causing damage to the sonar detector 855, four second dampers 84 are installed at the bottom of the lifting frame 81 to reduce shock to the lifting frame 81.

[0045] Working principle: First, move the lifting frame 81 to the water surface, and use the first motor 41 to rotate the threaded rod 42 to make the rubber block 46 contact the ground, increase the friction between the sonar detector lifting device and the floor, and prevent the sonar detector lifting device from moving during work. Then the second motor 52 rotates the gear 53, and the gear 53 engages with the rack 51. The rotation of the gear 53 can make the rack 51 slide in the slide groove 11, and then rotate the first connecting plate 54 and the second connecting plate 55. When the first and second connecting plates rotate, the lifting rod 62 will produce an angle tilt, lifting or lowering the lifting frame 81, and the third motor 651 drives the winding shaft 652 to rotate, which can retract or loosen the connecting line 64, so that the lifting frame can be lowered to a deeper bottom of the water.

[0046] The counterweight block 32 can prevent the support plate 1 from tipping over due to uneven weight on both sides. The design of the first and second dampers can ensure that the components in the lifting frame 81 will not be damaged when the sonar detector lifting device is moved, and can also ensure that when the lifting frame 81 descends to the bottom of the water, the lifting frame 81 will not be shaken when it hits stones or other hard objects, so that the components in the lifting frame 81 will be damaged.

[0047] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
