[0041] S1.3: Control system 4 controls second hydraulic cylinder 18 to extend, pushing hook 17 corresponding to the reinforcement assembly to swing toward speedboat 2 until hook 17 contacts fourth position sensor 19. Control system 4 then controls second hydraulic cylinder 18 to stop, thus reinforcing speedboat 2 and preventing the speedboat from becoming loose and causing safety issues.

[0042] S1.4: Control system 4 controls first hydraulic cylinder 6 to retract, pulling tailgate 1 to swing toward the stern compartment 5 of the vessel until tailgate 1 contacts second position sensor 12. Control system 4 then controls first hydraulic cylinder 6 to stop, retracting tailgate 1 and further preventing speedboat 2 from falling out.

[0043] S1.5: Use the two ends of the lashing ropes 15 corresponding to the fixing assembly to connect to the two sides of the stern of the speedboat 2 and the rope holder 16 respectively. The other ends of the lashing ropes 15 are passed around the speedboat 2 and tied to the rope hanging rod 14 to fix the speedboat 2 and prevent it from loosening.

[0044] S1.6: Lock the tailgate 1 with the locking device 26, close the control system 4, and complete the speedboat retrieval.

[0045] S2. Speedboat lowering:

[0046] S2.1: Release the locking device 26 corresponding to the tailgate 1;

[0047] S2.2: Loosen all the lashing ropes 15 corresponding to the fixing components to release the speedboat 2;

[0048] S2.3: Control system 4 is activated. Control system 4 controls first hydraulic cylinder 6 to extend, pushing tailgate 1 to swing away from the stern compartment 5 until tailgate 1 contacts third position sensor 13. Control system 4 then controls first hydraulic cylinder 6 to stop, allowing tailgate 1 to swing flush with the bottom of storage chamber 3, facilitating the speedboat 2 to slide down.

[0049] S2.4: Control system 4 controls second hydraulic cylinder 18 to retract, pushing hook 17 corresponding to the reinforcement assembly to swing toward the stern compartment 5 of the vessel until hook 17 contacts fifth position sensor 20. Control system 4 then controls second hydraulic cylinder 18 to stop, releasing the restraint of the reinforcement assembly on the speedboat.

[0050] S2.5: Control system 4 controls winch 7 to loosen wire rope 27. Speedboat 2, under its own weight, moves along storage chamber 3 toward tailgate 1 until it falls into the water and clears tailgate 1. Control system 4 then controls winch 7 to stop. The winch 7 then pulls speedboat 2 downward, preventing it from falling rapidly and further improving the stability of the lowering process.

[0051] S2.6: Release the steel wire rope 27 corresponding to the winch 7 and hang the steel wire rope 27 on the side of the tailgate 1 for easy access when retrieving the speedboat 2. Turn off the control system 4 to complete the lowering of the speedboat 2.

[0052] The utility model provides a method for folding and deploying a law enforcement speedboat, which can realize fast and safe folding and deploying of the speedboat.

[0053] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention. These modifications and improvements will not affect the effect of the implementation of the present invention and the practicality of the patent.
