[0045] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present application.

[0046] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present application. Figures 1 to 8 A right-angle bilge reinforcing structure suitable for a low-speed floating body provided by the present application is described below with reference to the drawings.

[0047] The low-speed floating body comprises a bottom plate 01 and a side plate 02, and the side plate 02 and the bottom plate 01 are connected vertically to form a right-angle bilge.

[0048] The right-angle bilge reinforcing structure suitable for the low-speed floating body comprises a reinforcing member 100 and a support member 200, the support member 200 is located on the side of the side plate 02 away from the bottom plate 01, the support member 200 is an integral extension of the bottom plate 01, that is, the support member 200 and the bottom plate 01 are an integral flat plate, the side plate 02 is connected to the integral flat plate vertically and forms an inverted T-shaped structure with the integral flat plate, and the side plate 02 and the integral flat plate are connected by welding.

[0049] The reinforcing member 100 is arranged between the side plate 02 and the support member 200, and the end of the reinforcing member 100 away from the connection between the side plate 02 and the support member 200 is welded to the side plate 02 and the support member 200.

[0050] It can be understood that in the related art, the side plate 02 and the bottom plate 01 of the floating body are arranged vertically, and an angle steel is covered on the outside of the side plate 02 and the bottom plate 01 to weld them, the connection strength is low, and the construction process is relatively complex.

[0051] The scheme of the embodiment extends the support member 200 outwardly on the bottom plate 01 of the floating body, so that the bilge forms an inverted T-shaped structure, the side plate 02 and the bottom plate 01 are positioned conveniently and welded conveniently, the overall process is simple, and the support member 200 and the side plate 02 form a reinforcing area, the reinforcing member 100 is welded in the area, and the connection strength of the right-angle bilge is greatly improved.

[0052] In one of the embodiments, referring to Figure 1 both sides of the side plate 02 are welded to the integral flat plate, the reinforcing member 100 is a fan-shaped structure, an angle is arranged at the center of the reinforcing member 100 to avoid the weld, and the angle is smoothly transitioned to reduce stress concentration. Preferably, the angle of the reinforcing member 100 is arc-shaped, so that the overall structure of the reinforcing member 100 is similar to a fan ring, and a fillet is arranged at the junction of the arc-shaped profile of the angle and the profile of the two sides to reduce stress concentration. Naturally, the angle can also be arranged as a bevel, and a fillet is arranged at the junction of the bevel and the profile of the two sides. The welding between the reinforcing member 100 and the side plate 02 and the support plate 200 is groove welding, and the welding groove is arranged on the reinforcing member 100 to enhance the connection strength.

[0053] Further, in the embodiment where the reinforcing member 100 is in a fan-shaped structure, the side plate 02 can also be arranged to be welded only at the joint with the bottom plate 01, that is, the side plate 02 is welded at the joint with the side of the whole flat plate located inside the floating body, and the welding process adopts the single-side welding and double-side connecting process, in this way, there is no obvious weld joint at the joint between the side plate 02 and the support member 200, and the reinforcing member 100 does not need to be provided with a missing corner to avoid the weld joint at the side plate 02 and the support member 200, and then the reinforcing member 100 can be arranged in a complete fan-shaped structure, and it can be understood that the single-side welding and double-side connecting process is relatively complex compared with the double-side welding process, and the person skilled in the art can select according to the needs.

[0054] In the embodiment, the reinforcing member 100 is arranged in a fan-shaped structure, the reinforcing member 100 is similar to a solid structure, has a large thickness, and has a large connecting strength after assembly and welding, and can be suitable for a large-tonnage floating body.

[0055] In one of the embodiments, referring to Figure 2 , both sides of the side plate 02 are welded with the whole flat plate, and the reinforcing member 100 is an outward convex arc-shaped plate, which can save materials under the premise of meeting the strength requirement, and is suitable for a floating body with a relatively small tonnage. Moreover, a circular steel pipe can be used for processing, and a quarter of the circular steel pipe does not need to be cut to avoid the weld joint, and the processing process is relatively simple.

[0056] In one of the embodiments, referring to Figure 3 , both sides of the side plate 02 are welded with the whole flat plate, and the reinforcing member 100 is an outward convex arc-shaped plate, the side plate 02, the support member 200 and the reinforcing member 100 form an accommodating cavity, and the accommodating cavity is filled with a repairing agent.

[0057] In the embodiment, the reinforcing member 100 is arranged as an outward convex arc-shaped plate, so that the reinforcing member 100, the support member 200 and the side plate 02 form an accommodating cavity, and the accommodating cavity is filled with a repairing agent, when the weld joint of the reinforcing member 100 is opened to form a small gap, water seeps into the accommodating cavity from the gap of the weld joint and reacts with the repairing agent in the accommodating cavity, and the repairing agent can repair the crack at the weld joint after solidification, so as to avoid further expansion of the weld joint and improve the use performance of the bilge.

[0058] Further, referring to Figure 3 , the side plate 02 is provided with a communication port 021, the communication port 021 penetrates through both sides of the side plate 02, so as to communicate the accommodating cavity and the space inside the floating body, and the communication port 021 is connected with a gas pressure device to control the gas pressure in the accommodating cavity.

[0059] In the scheme of the embodiment, the communication port 021 can be used as a filling port for the repair agent, and the filling of the repair agent can be facilitated. Meanwhile, the gas pressure device is connected to the communication port 021, and the gas pressure device is used to inflate the containing cavity, so that the containing cavity can maintain a certain pressure. Preferably, the gas pressure in the containing cavity is slightly higher than the external water pressure (so that the gas pressure in the containing cavity can balance the external water pressure as much as possible, so as to avoid that the external water pressure causes too large pressure on the weld position, and thus affects the strength and service life of the weld). By detecting the change of the gas pressure in the containing cavity, it can be determined whether the weld position of the reinforcement 100 is leaking. When the weld position of the reinforcement 100 leaks, the gas pressure in the containing cavity decreases, and water seeps into the containing cavity through the gap at the weld position and reacts with the repair agent in the containing cavity, and the repair agent gradually solidifies to block the crack. During the process of blocking the crack, the gas pressure in the containing cavity is changed to detect whether the crack is successfully blocked. The specific steps are as follows. After the crack occurs, the system detects that the gas pressure in the containing cavity decreases. At this time, the gas is continuously supplied into the containing cavity for a period of time, so that the gas flow can blow enough repair agent particles to the weld position (when the crack at the weld position is relatively large, the repair agent can be squeezed into the joint between the reinforcement 100 and the side plate 02 or the joint between the reinforcement 100 and the support 200 from the inside of the weld). Then, the gas supply amount is reduced, so that the gas pressure in the containing cavity decreases, and a small amount of water can seep into the containing cavity and react with the repair agent particles in the containing cavity. After that, the gas supply amount is increased again, so that the repair agent particles are blown to the crack. The above steps are repeated until the gas pressure in the containing cavity does not decrease after the gas is supplied, which means that the repair agent has completely blocked the crack.

[0060] In the scheme of the embodiment, the reinforcement 100 is an outwardly convex arc-shaped plate. When the gas pressure in the containing cavity is increased, the inside of the weld of the reinforcement 100 (the joint between the reinforcement 100 and the side plate 02 or the support 200) can be slightly raised, so that the gap is increased, and more repair agent can be squeezed into the gap. After the gas pressure in the containing cavity is reduced, the reinforcement 100 is pressed against the side plate 02 and the support 200 again, so that the repair agent that has reacted with water is further squeezed, so that the repair agent is more densely filled into the gap, and the crack repair effect is improved.

[0061] In one of the embodiments, referring to Figure 4 , both sides of the side plate 02 are welded with the whole plate, the reinforcement 100 is an inwardly concave arc-shaped plate, the side plate 02, the support 200 and the reinforcement 100 form a containing cavity, and the containing cavity is filled with the repair agent. The side plate 02 is provided with a communication port 021, and the communication port 021 is connected to a gas pressure device to control the gas pressure in the containing cavity.

[0062] The scheme of the embodiment is different from the scheme of the reinforcing member 100 being an outward convex circular arc plate in that the reinforcing member 100 is an inward concave circular arc plate, and the included angle between the reinforcing member 100 and the side plate 02 and the support plate is smaller. When the internal pressure of the accommodating cavity increases, the joint gap between the reinforcing member 100 and the side plate 02 and the support plate increases (the gap increases to a smaller extent than the scheme of the reinforcing member 100 being an outward convex arc plate), and the repair agent is extruded into the gap under the blowing of the airflow. When the internal pressure of the accommodating cavity decreases, the reinforcing member 100 and the side plate 02 and the support plate are extruded again, thereby extruding the repair agent. Because the included angle between the reinforcing member 100 and the side plate 02 and the support plate is smaller, the extrusion range and effect of the repair agent are better, and the repair agent is more likely to seal the gap.

[0063] In one embodiment, in order to enable the repair agent to better enter the gap between the reinforcing member 100 and the side plate 02 and the support plate and to be better extruded to repair the gap, the side plate 02 is welded to the overall plate on both sides, the side plate 02, the support member 200 and the reinforcing member 100 enclose the accommodating cavity, and the accommodating cavity is filled with the repair agent. The side plate 02 is provided with a communication port 021, and the communication port 021 is connected to the air pressure device. Figure 5

[0064] The reinforcing member 100 includes a deformation portion 101 and a reinforcing portion 102 connected to both ends of the deformation portion 101. The reinforcing portion 102 is connected to the side plate 02 and the support member 200, and the deformation portion 101 is initially an inward concave arc. When the internal pressure in the accommodating cavity increases to a preset value, the deformation portion 101 can be deformed into an outward convex arc.

[0065] The scheme of the embodiment combines the schemes of the reinforcing member 100 being an outward convex circular arc plate and an inward concave circular arc plate by setting the reinforcing member 100 to include the deformation portion 101 and the reinforcing portion 102 connected to both ends of the deformation portion 101. The included angle between the reinforcing member 100 and the side plate 02 and the support plate is moderate. When the internal pressure of the accommodating cavity increases, the deformation portion 101 gradually changes from an inward concave arc to an outward convex circular arc, thereby pulling the reinforcing portion 102 to better expand the gap and facilitate the repair agent to enter. When the internal pressure of the accommodating cavity decreases, the deformation portion 101 gradually changes from an outward convex circular arc to an inward concave circular arc, thereby pulling the reinforcing portion 102 to extrude the repair agent in the gap and improving the extrusion effect of the repair agent, which is more conducive to repairing the weld.

[0066] Specifically, the deformation portion 101 can be an integral structure with the reinforcing portion 102 and be made of the same material to ensure the strength of the reinforcing member 100. Preferably, the deformation portion 101 is set to a zigzag structure to increase the deformation ability.

[0067] ​Further, the right-angle bilge reinforcement structure suitable for low-speed floating bodies of the present application further comprises an adjusting assembly 300 arranged at the communication port 021, which is configured to limit the deformation amount of the deformation portion 101 to be below the maximum deformation amount after the welding seam is repaired, so as to avoid excessive pulling of the repaired welding seam due to excessive deformation of the deformation portion 101, and to avoid damage to the repaired welding seam, thereby affecting the repair effect and the use strength.

[0068] With reference to Figure 5 , the adjusting assembly 300 comprises a mounting seat 310, a sliding valve 320, a steel wire 340 and an adjusting screw 330. The mounting seat 310 is arranged at the communication port 021 and is externally connected to the air pressure device. An air passage is formed in the mounting seat 310 and is in communication with the communication port 021. The sliding valve 320 is slidingly inserted into the mounting seat 310. An elastic member 350 is arranged between the sliding valve 320 and the mounting seat 310, which enables the sliding valve 320 to have a tendency to slide outward. The sliding valve 320 can change the size of the air passage and block the air passage.

[0069] The adjusting screw 330 is screwed into the center of the sliding valve 320. One end of the steel wire 340 is connected to the deformation portion 101, and the other end of the steel wire 340 is connected to the adjusting screw 330.

[0070] In the initial state, the deformation portion 101 is in a concave arc shape. The adjusting screw 330 is rotated to the deepest position in the sliding valve 320. The air passage is in an open state. With reference to Figure 6 ; the air pressure device passes air into the containing cavity through the air passage, so that the containing cavity maintains a certain pressure. When it is detected that the pressure in the containing cavity decreases, it indicates that there is a leak in the welding seam between the reinforcement 100 and the side plate 02 or the support plate. Then, the air pressure in the containing cavity is increased. The repair agent in the containing cavity tends to move to the welding seam of the reinforcement 100. At the same time, as the air pressure increases, the deformation portion 101 of the reinforcement 100 gradually changes from a concave shape to a convex shape, so that the gap between the reinforcement 100 and the side plate 02 and the support plate increases, facilitating the entry of the repair agent into the gap. At this time, the air passage is still in an open state. Then, the air pressure in the containing cavity is appropriately reduced, so that the air pressure in the containing cavity is slightly less than the external water pressure. Under the action of the external water pressure, a small amount of water enters the crack and reacts with the repair agent. At the same time, the deformation portion 101 is reset to a certain extent, the gap between the reinforcement 100 and the side plate 02 and the support plate is reduced, the repair agent is extruded, and the repair effect is improved. The above steps are repeated until the air pressure in the containing cavity is maintained, and the air pressure no longer decreases, which indicates that the repair agent has plugged the crack. After the welding seam is repaired, the adjusting screw 330 is rotated. Since the length of the steel wire 340 is constant, the sliding plug moves inward relative to the mounting seat 310, reducing the initial size of the air passage. With reference to Figure 7In use, the weld is protected by balancing the pressure in the containing cavity with the external water pressure by venting the containing cavity, and by causing the pressure in the containing cavity to be slightly greater than the external water pressure. Since the position and the draft of the floating body in the water area are dynamically changing, the pressure in the containing cavity also dynamically changes with the external water pressure. In the process of adjusting the pressure in the containing cavity, if the pressure in the containing cavity is too large, the deformation portion 101 protrudes too much outward, and when the deformation portion 101 protrudes too much outward, the slide valve 320 is pulled to move inward to block the air passage, so as to avoid the pressure in the containing cavity being too large, and to avoid the deformation portion 101 protruding too much outward, to protect the repaired weld from being damaged again.
