AI Technical Summary
Existing sailboat rudders are prone to damage when encountering obstacles, especially straight-insertion rudders which require underwater repair, and pivot rudders which require underwater cutting to remove obstructions, resulting in difficult and costly maintenance.
Design a rudder blade fuse protection mechanism, which adopts a limit safety plate and a hinged rotating shaft structure. When the rudder blade is obstructed, the safety plate breaks, and the rudder blade automatically rotates over the obstacle and recovers. After passing the obstacle, it automatically resets. The safety plate can be replaced or the entangled object can be removed manually.
It improves the safety of sailing, reduces diving maintenance work, lowers maintenance costs, and increases the efficiency of safe navigation.

[0006] Preferably, the limit safety sheet is a glass fiber safety sheet or a metal safety sheet or a plastic safety sheet.
[0007] Preferably, the both sides of the corresponding position of the ship body are respectively equipped with slot, and the both ends of the limit safety sheet are fixed by cooperating with the slot.
[0008] Preferably, the upper end of the rudder shaft sleeve is hingedly connected on the ship body through a hinged shaft.
[0009] Preferably, the hinged shaft is connected between the rudder plate through a diagonal pull rod.
[0010] Beneficial effects: the utility model provides a rudder blade fuse protection mechanism, which can protect the integrity of the sailboat rudder mechanism, quickly restore the function after removing the danger, and continue to sail. Reduce the risk of sea navigation, reduce the diving and maintenance work of the crew, reduce the maintenance and use cost, and improve the safety navigation efficiency. BRIEF DESCRIPTION OF DRAWINGS

[0016] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.
[0017] Example 1: As Figures 1-3 As shown, a rudder blade fuse protection mechanism includes a rudder blade assembly, which includes a rudder blade 11, a rudder shaft sleeve 12, a rudder lever 13, and a rudder plate 14. The rudder lever 13 rotates within the rudder shaft sleeve 12 and drives the lower rudder blade 11 to rotate. The rudder shaft sleeve 12 is connected to the rudder plate 14, and the rudder plate 14 is limited by a limiting groove 22 at a corresponding position on the hull 2. The upper end of the rudder lever 13 is the transmission input end, that is, the rudder pivot 41 is connected to the upper end of the rudder lever 13 through the rudder connecting rod 42. The upper end of the rudder shaft sleeve 12 is hinged to the hull 2 through a hinged pivot 15 so that the rudder shaft sleeve 12 can swing back and forth. A limiting safety piece 3 is provided on the outer side of the rudder plate 14. The limiting safety piece 3 is used to limit the rudder plate 14 and prevent it from swinging outward. The limiting safety piece 3 is a fiberglass safety piece, a metal safety piece, or a plastic safety piece.
[0018] Specifically, slots 21 are provided on both sides of the corresponding position of the hull 2. The two ends of the limiting safety plate 3 are fixed by cooperating with the slots 21. Alternatively, it can be fixed by bolts or other detachable methods, or by the slots 21 cooperating with bolts.
[0019] In some embodiments, the hinge shaft 15 and the rudder plate 14 are connected by a tie rod 16, and a stable triangular structure is formed between the hinge shaft 15, the tie rod 16 and the rudder shaft sleeve 12 to ensure stability.
[0020] The working principle of the utility model is: when encountering grounding or obstacles, the rudder blade 11 is impacted or hindered, the impact force of the rudder blade 11 acts on the limiting safety sheet 3, if the limiting performance limit of the limiting safety sheet 3 is exceeded, the limiting safety sheet 3 is broken or separated from the limiting position, the rudder blade 11 rotates and lifts to slide over the obstacles, after passing through the obstacle area, due to the gravity of the rudder, the rudder blade 11 falls back to the original position, the new limiting safety sheet 3 is installed back to the original position, and the function of the rudder blade 11 is restored.
[0021] When the rudder blade 11 is wound by fishing nets, waterweeds and sundries, the crew can remove the limiting safety sheet 3, lift the rudder blade 11, and the fishing nets, waterweeds and sundries slide down along the water and are unwound.
[0022] The above disclosed are only several specific embodiments of the utility model, but the utility model embodiments are not limited to this, any change that can be thought of by any person skilled in the art should fall into the protection scope of the utility model.
