Abstract

A multifunctional unmanned boat catamaran structure, including a hull, a support frame, a box, a fixture, a propeller, a support plate, a connecting plate, bolts and nuts, and four connecting plates are connected to two hulls to form a catamaran The structure, the hull and the support frame are welded and fixed as a whole, and the rest of the parts are connected by bolts, so they can be easily disassembled, which is convenient for transportation. The surface of the hull is streamlined, the shape of the hull is wide and flat, and the bow and the left and right sides of the hull are slightly pointed. The support frame has an angle of 90 degrees on both sides, that is, "L" shape. The support plate is connected with the two sides of the 90 degrees by bolts, and two postures of the hull can be adjusted: in shallow water, the hull is wide and flat. One side floats above the water surface, that is, stands horizontally on the water surface, which can reduce the draft and prevent you from running aground in shallow water; in deep water, the slightly pointed end floats above the water surface, that is, stands vertically on the water surface, which can increase the draft and improve The stability of the unmanned boat on the water surface.

Description

A multifunctional unmanned boat catamaran structure

technical field

The invention relates to a ship, specifically, the hull can be disassembled and adjusted into two structures, which are respectively suitable for shallow water channels and deep water channels. the

Background technique

At present, the projects and content of marine surveying and mapping are increasing, which puts forward higher and higher requirements for the research and development and application of surveying and mapping methods and technologies. In offshore bathymetric surveys, manual surveying and mapping is usually carried out by boat, line by line, and area by line. The survey is generally divided into two parts: one is the deep sea area far from the shore (water depth exceeds 15m); the other is the shallow sea area near the shore (water depth is 0-15m). the

When working in deep sea areas, large ships (with a draft of more than 3.5m) are usually used to set up measuring equipment for 24-hour continuous measurement. If the measuring equipment operates normally and the weather conditions permit, this part of the measurement is generally smooth. the

When working in the near-shore shallow sea area, because the draft of the large ship is too deep to carry out, it can only be carried out by a small ship (with a draft below 1m). In actual operation, there are the following problems: first, it is difficult to set up measuring equipment on small boats; second, small boats generally can only operate when the tide is high, and cannot achieve all-weather operations; third, the near-shore water environment is usually very complicated: shoals, hidden reefs etc. all will bring very big potential safety hazard to surveying work; Its 4th, the working environment of the field surveyor on the small boat is extremely difficult, and safety can't be guaranteed. the

The above shows that in marine surveying and mapping, it is necessary to use ships with different drafts and sizes according to different water depths, and the operation difficulty in shallow water areas is much greater than that in deep water areas. It cannot be put into a vehicle or ship at will for transportation. the

Contents of the invention

In order to overcome the inability of current ships to operate in deep water areas and shallow water areas at the same time, and the transportation is inconvenient, the present invention proposes a multifunctional unmanned boat catamaran structure, which is convenient for disassembly and transportation, and can be disassembled and reassembled according to the draft. In this way, the attitude of the hull is adjusted to change the draft. the

In order to solve the above technical problems, the technical solution adopted by the present invention to solve the technical problems is: a multifunctional unmanned boat catamaran structure, including the hull, support frame, box body, fixture, propeller, support plate, connecting plate 1. Bolts and nuts, characterized in that the hull is a streamlined structure, the hull is wide and flat, the bow and the left and right sides of the hull are slightly pointed, and the parts are connected by bolts. The hull and the supporting frame are welded and fixed as a whole, the supporting plate and the supporting frame, the supporting plate and the connecting plate, the box body and the connecting plate are all connected by bolts, and the propeller is connected with the connecting plate through a clamp. The support frame is in the shape of a 90-degree included angle on both sides, that is, an "L" shape, and the support plate and the support frame are connected by bolts on both sides at 90 degrees. the

The beneficial effect of the present invention is: the components in the catamaran structure are connected by bolts, can be disassembled and disassembled, which is convenient for transportation in a car or on a ship, and the posture of the hull can be adjusted according to the water depth. In shallow water, the hull can stand horizontally above the water surface, reducing the draft, so as not to run aground in shallow water. In the depth of water, the hull can be erected above the water surface to increase the draft and improve the stability on the water surface. the

specific embodiment

The present invention will be further described below in conjunction with the accompanying drawings and embodiments. the

As shown in the figure 1. Hull, 2. Support frame, 3. Box body, 4. Clamp, 5. Propeller, 6. Support plate, 7. Connecting plate, 8. Nut, 9. Bolt. the

As shown in Figure 1, the structure of the catamaran is formed by connecting four connecting plates (7) with two hulls (1), two of which are installed in the middle of the hulls (1), and the box body (3) is connected by bolts (9). ) nuts (8) are connected and fixed with these two connecting plates (7), and the remaining two are installed on the bow and stern respectively, and the propeller (5) is fixed on the connecting plate (7) at the stern by the clamp (4), and propulsion The device (5) can adjust the depth of water inflow through the clamp (4). On the basis of satisfying the sufficient strength of the catamaran structure, ensure that the connecting plate (7) has a sufficient length so that the two propellers (5) can be completely accommodated between the two hulls (1). At least two groups of bolts (9) and nuts (8) are connected at the joint between one end of each connecting plate (7) and the support plate (6), so that no misalignment will occur between the two hulls (1). the

As shown in Figure 1, the support frame (2) and the hull (1) are welded and fixed as a whole, the support frame (2) and the support plate (6), the support plate (6) and the connecting plate (7), the box body (3 ) and the connecting plate (7) are connected by bolts (9) and nuts (8), wherein the required instruments and equipment for the unmanned boat are placed in the box. the

As shown in Figure 2, the shape of the support frame (2) in the catamaran structure is characterized by two sides with an angle of 90 degrees, that is, an "L" shape, and the support frame (2) has been welded to the hull (1) Be fixed as a whole, on the basis that the bracing frame (2) in Fig. 2 has sufficient strength at the weld, its bottom edge must ensure sufficient length so that the bolt (9) and the hull (1) will not collide. Since the connecting plate (7) and the box body (3) in the catamaran structure are installed on the support plate (6), the attitude of the hull (1) can pass through the support plate (6) and the support frame (2). Two sides with a middle angle of 90 degrees are connected to adjust two attitudes of the hull (1), as shown in Figure 2 and Figure 4 respectively. the

As shown in Figure 2, the surface of the hull (1) is streamlined, the shape of the hull is wide and flat, the bow and the left and right sides of the hull are slightly pointed, so two postures can be adjusted along with the hull (1). Then the wide and flat side floats on the water surface, that is, it stands horizontally on the water surface. At this time, the draft can be reduced, so as not to run aground in shallow water, as shown in Figure 1; in deep water, the slightly pointed end floats on the water surface. Above the water surface, that is, standing on the water surface, the draft can be increased at this time, and the stability on the water surface can be improved, as shown in Figure 3. the
