Implementation

[0025] The following is combined with Figure 1-4 This application is described in further detail.

[0026] The present application embodiment discloses a fixed marine remote sensing monitoring device, referring to Figure 1 and Figure 3 , including a vertical fixing rod 1, the fixing rod 1 is made of fiberglass, is tubular, has a diameter set to 15cm, and a wall thickness set to 1cm. The above two parameters can be changed and adapted according to the specific sea conditions.

[0027] Reference Figure 1 and Figure 2 The upper end of the fixed rod 1 is provided with an image control point target 2, which includes a square target plate 21 made of stainless steel. Two cross-staggered reinforcing ribs 23 are welded on one side of the target plate 21. The reinforcing ribs 23 pass through the center of the target plate 21, and the two reinforcing ribs 23 are parallel to the adjacent two sides of the target plate 21. Four square image control plotting boards 22 are integrally arranged on the other side of the target plate 21. The image control plotting boards 22 are spliced ​​together to fill the other side of the target plate 21, and the four image control plotting boards 22 are alternately painted with yellow pigment and red pigment for remote sensing image recognition.

[0028] Reference Figure 2A connecting piece 5 is also provided on the surface of the target plate 21 provided with the reinforcing ribs 23. The connecting piece 5 includes an arc-shaped first fixing plate 51 and an arc-shaped second fixing plate 52. A connecting ring 53 is coaxially and integrally provided on one end of the first fixing plate 51 in the axial direction. Four card interfaces 531 are provided on the end of the connecting ring 53 away from the first fixing plate 51. The four card interfaces 531 are circumferentially spaced around the axis of the connecting ring 53.

[0029] Reference Figure 2 The connecting ring 53 is coaxially welded on the surface of the target plate 21 provided with the reinforcing ribs 23 , and the four card interfaces 531 are respectively matched and connected to the two reinforcing ribs 23 in pairs.

[0030] The target plate 21 is reinforced by the reinforcing ribs 23, so that the target plate 21 is not easily bent by the sea wind when working at sea, resulting in a decrease or even disappearance of the recognition effect. At the same time, the torsion between the connecting ring 53 and the target plate 21 is limited by the cooperation between the card interface 531 and the reinforcing ribs 23, which reduces the types of external forces that the welding point needs to withstand after the target plate 21 and the connecting ring 53 are welded, and improves the connection stability between the target plate 21 and the connecting ring 53.

[0031] Reference Figure 2 and Figure 3 The upper end of the fixing rod 1 is coaxially inserted into the connecting ring 53, and four clamping blocks 532 are integrally arranged on the inner wall of the connecting ring 53. The clamping blocks 532 are circumferentially distributed along the inner wall of the connecting ring 53. Four clamping grooves 11 are also arranged on the upper end surface of the fixing rod 1. The clamping grooves 11 penetrate the upper side wall of the fixing rod 1. The clamping grooves 11 are arranged at intervals along the circumferential direction of the axis of the fixing rod 1. The four clamping blocks 532 are correspondingly embedded in the four clamping grooves 11 one by one, so as to limit the torsional movement between the fixing rod 1, the connecting ring 53 and the first fixing plate 51.

[0032] Reference Figure 2 and Figure 3 The second fixing plate 52 is fixedly mounted on the first fixing plate 51 by bolts, the inner walls of the second fixing plate 52 and the first fixing plate 51 are both in close contact with the side walls of the fixing rod 1, and the upper end of the fixing rod 1 is locked on the first fixing plate 51 by the second fixing plate 52, completing the installation of the target plate 21 on the fixing rod 1.

[0033] Reference Figure 1 and Figure 3 The fixing mechanism 3 at the bottom of the fixing rod 1 includes a conical guide block 31, and a cylindrical connecting block 32 is coaxially arranged on the plane end of the guide block 31. The connecting block 32 is inserted into the lower end of the fixing rod 1. When the fixing rod 1 is inserted into the seabed, it is more convenient to guide the insertion through the conical guide block 31. At the same time, a fixing member 4 is arranged on the guide block 31 to fix the guide block 31 in the seabed.

[0034] Reference Figure 3 and Figure 4 A mounting hole 321 is coaxially formed on one end face of the connecting block 32 away from the guide block 31, and the mounting hole 321 extends into the guide block 31. Four sliding holes 322 are circumferentially spaced around the axis of the mounting hole 321 on the side wall of the mounting hole 321 section in the guide block 31, and the sliding holes 322 penetrate the side wall of the guide block 31. The fixing member 4 includes a fixing spike 42 slidably mounted in the sliding hole 322 and a top block 41 slidably mounted in the mounting hole 321. The sharp spike end of the fixing spike 42 is located in the end port of the sliding hole 322 penetrating the side wall of the guide block 31, and the other end of the fixing spike 42 is a flat end and extends into the mounting hole 321.

[0035] Reference Figure 3 and Figure 4 , the direction toward the target plate 21 is defined as upward, the lower end of the top block 41 is a sliding section 411, and the cross section of the sliding section 411 is square. The number of sides of the cross section of the sliding section 411 is designed accordingly according to the number of fixed spikes 42. The upper end of the top block 41 is a guide section 412, and the guide section 412 is also designed as four side backs, and the four side walls are connected to the four side walls of the sliding section 411 in a one-to-one correspondence. The side wall of the guide section 412 is defined as a guide surface 413, and the guide surface 413 is arc-shaped and concave, and a fillet 414 is provided at the connecting line between the guide surface 413 and the side wall of the sliding section 411.

[0036] Reference Figure 3 and Figure 4 The end surface area of ​​the guide section 412 that is away from the sliding section 411 is smaller than the end surface area of ​​the guide section 412 that is connected to the sliding section 411. The flat end of the fixed thorn 42 is pressed against the guide surface 413, and the fixed thorn 42 can be pushed out of the sliding hole 322 by sliding the top block 41. At the same time, the sliding hole 322 is designed to be inclined upward. When the top block 41 pushes the fixed thorn 42 to extend out of the sliding hole 322, the fixed thorn 42 becomes a barb on the side wall of the guide block 31, making it difficult for the guide block 31 to be pulled out from the seabed.

[0037] Reference Figure 3 and Figure 4 A rectangular lifting block 6 is slidably installed at the center of the surface of the target plate 21 facing the fixed rod 1, and a lifting bolt 7 is rotatably installed at the center of the surface of the target plate 21 away from the fixed rod 1. The lifting block 6 slides along the axis direction of the fixed rod 1, and the lifting bolt 7 is coaxial with the fixed rod 1. A connecting threaded hole 61 is coaxially opened on one end surface of the lifting block 6 facing the lifting bolt 7. The connecting threaded hole 61 is threadedly matched with the lifting bolt 7. One end of the lifting bolt 7 is threadedly connected to the connecting threaded hole 61. The lifting block 6 is driven to slide by rotating the lifting bolt 7.

[0038] Reference Figure 3 and Figure 4 The bottom wall of the lifting block 6 and the top of the top block 41 are connected by a pull rope 8 made of steel wire. The top block 41 can be driven to slide by rotating the lifting bolt 7 through the pull rope 8. A retaining ring 9 is coaxially welded on the inner wall of the mounting hole 321 in the guide block 31. When the side wall of the sliding section 411 of the top block 41 closes the sliding hole 322, the guide surface 413 of the top block 41 presses against the inner wall of the retaining ring 9. Through the cooperation between the top block 41 and the retaining ring 9, on the one hand, it is convenient to judge the tightening degree of the lifting bolt 7, which can effectively prevent the top block 41 from sliding too far. On the other hand, through the cooperation between the pull rope 8, the retaining ring 9, the lifting bolt 7 and the lifting block 6, the guide block 31 can be fixed on the fixing rod 1. After the fixing rod 1 is inserted into the seabed, the cooperation between the above two can effectively prevent the fixing rod 1 from falling off the connecting block 32.

[0039] The implementation principle of a fixed marine remote sensing monitoring device in an embodiment of the present application is: the breeding area is marked by image control point targets 2, so that the breeding area in the drone remote sensing aerial photos can be recognized by the computer, and long-term continuous breeding area monitoring is achieved through the cooperation between the computer and the drone.

[0040] At the same time, when inserting the image control point target 2, after the fixing rod 1 is inserted into the seabed, the pulling bolt 7 is rotated until the pulling bolt 7 is tightened. At this time, the top block 41 pushes the fixing spike 42 to extend out of the sliding hole 322 and insert into the soil of the seabed, completing the fixation of the fixing rod 1.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
