DETAILED DESCRIPTION

[0057] The present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention may be implemented in various forms and is not limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete and to fully convey the scope of the present invention to those skilled in the art.

[0058] Example 1:

[0059] See also Figure 1-3 A water intake device is used on a ship or a mobile platform, comprising:

[0060] A water intake pipe 1, one end of which is a water intake end and the other end is a connection end;

[0061] The pulling device 2 can drive the water intake pipe 1 to move; the pulling device 2 can be a winch and installed horizontally. When the water intake rate requirement is large, resulting in a large diameter of the water intake pipe 1 and its bending radius, a vertical (drum) winch can be considered. The water intake pipe is connected to the water pump through a rotary joint, so that the water pump can still work normally when the water intake pipe is wound on the winch, thereby meeting the function of retracting and storing the flexible hose while effectively controlling the height of the highest point of the water intake pipe 1. The winch can be optionally equipped with a pipe length indicator and a tension indicator function, increase the release and recovery limit, and be equipped with a cable arranger according to the layout selection.

[0062] A guide device, the guide device is used to guide the moving direction of the water intake pipe 1;

[0063] A water pump 6 is connected to the connecting end of the water intake pipe 1 and pumps water through the water intake pipe 1 .

[0064] The water intake pipe 1 is pulled up by the lifting device 2 to facilitate recovery, and the water intake pipe 1 is prevented from deviating from the predetermined direction by the guide device. When recovering and storing, the lifting device 2 is operated to recover the water intake pipe 1 to the limit stop, and the guide device is operated to lift it to the storage position. The lifting device 2 is slowly operated to drop the counterweight end onto the deck, fixed, and stopped to complete the recovery and storage.

[0065] Specifically, the guiding device includes:

[0066] The lifting arm 3 includes a base, a lifting arm that can rotate relative to the base, and a driving device that drives the lifting arm to rotate; the driving device can be optionally hydraulically driven, or it can share the same driving device as the pulling device 2.

[0067] The first pulley group 4 includes at least one first fixed pulley installed on the base and at least one second fixed pulley installed on the boom; when the deep-sea water intake device is arranged along the width of the ship, the last fixed pulley is designed to be flippable to adapt to a larger deviation angle of the water intake pipe 1 along the length of the ship.

[0068] The water intake pipe 1 passes through the first fixed pulley and the second fixed pulley in sequence.

[0069] Specifically, the water intake pipe 1 includes:

[0070] Inner sheath 9;

[0071] A stainless steel tube 10, which is located inside the inner sheath 9 and can be replaced with a hose according to actual work requirements;

[0072] A steel wire rope 30, the steel wire rope 30 being located inside the inner sheath 9;

[0073] Armored steel wire 8, the armored steel wire 8 is arranged outside the inner sheath 9;

[0074] The outer sheath 7 is arranged outside the armored steel wire 8; the water intake pipe 1 enhances the water intake function, water intake rate and maximum water intake depth through the above design.

[0075] The interior of the inner sheath 9 is filled with a soft filler, which is a polymer material, such as polypropylene, polypropylene, etc. A first counterweight 5 is provided at the water intake end of the water intake pipe 1 .

[0076] Specifically, a second counterweight 12 is detachably mounted on the first counterweight 5. The first counterweight 5 and the second counterweight 12 can reduce the deviation of the water intake flexible pipe caused by wind, waves, and currents. The weight of the counterweight needs to be determined according to the size of the water intake pipe 1, the water intake depth, and the water intake design working conditions. In actual use, different locations and times may require different water intake depths and encounter different environmental conditions. It is unnecessary and uneconomical to always maintain the maximum counterweight. Therefore, the counterweight is divided into a basic counterweight and a detachable counterweight. That is, the first counterweight 5 and the second counterweight 12, the first counterweight 5 is installed on a small length of the end.

[0077] Example 2:

[0084] Fixed seat;

[0085] A third fixed pulley 13, the third fixed pulley 13 being arranged on the fixed seat;

[0086] The water intake pipe 1 passes through the third fixed pulley 13 .

[0087] Specifically, the water intake pipe 1 includes:

[0088] Middle joint 14;

[0089] A rubber hose group, comprising a plurality of first rubber hoses 27 , wherein adjacent first rubber hoses 27 are connected via intermediate joints 14 ;

[0090] a second rubber hose 28, one end of which is connected to one end of the rubber hose assembly;

[0091] Connecting accessory 18, the other end of the second rubber hose 28 is connected to the connecting accessory 18;

[0092] A pressure-bearing joint 15, one end of which is connected to the other end of the rubber hose assembly

[0093] a third rubber hose 29 , one end of which is connected to the other end of the pressure-bearing joint 15 ;

[0094] an end flange 17 to which the other end of the third rubber hose 29 is connected;

[0095] The first traction rope 11 is located inside the water intake pipe 1 and is connected to the pressure-bearing joint 15. The first traction rope 11 is a steel rope, which allows the water intake pipe 1 to expand and contract along the rope length and limits radial deviation.

[0096] The water intake pipe 1 is connected to the water pump 6 via an end flange 17. The first traction rope 11 passes through a connecting attachment 18 and is connected to a third counterweight 25. The third counterweight 25 can reduce the deviation of the water intake pipe 1 caused by wind, waves, and currents. The weight of the third counterweight 25 should be determined based on the size of the water intake pipe 1, the water intake depth, and the designed water intake conditions.

[0097] Specifically, it also includes a crane 24, the output end of which is connected to the third counterweight 25 through a second traction rope. The main function of the crane 24 is to lift the configuration out and retract it onto the deck, and during the process of placing and recovering the water intake pipe 1, it bears the gravity of the third counterweight 25, thereby reducing the force on the water intake pipe 1 during these processes.

[0098] Specifically, an anti-bending sheath 19 is provided on the water intake pipe 1 near the pressure joint 15. The material of the anti-bending sheath 19 can be polyurethane, and its function is to limit the bending radius of the connection between the hose and the pressure joint 15. An anti-pressure and wear sheath 20 is provided on the water intake pipe 1 between the anti-bending sheath 19 and the connecting accessory 18. The material of the anti-pressure and wear sheath 20 can be rubber, and its function is to limit the extrusion and wear between the hose and the hull under certain working conditions.

[0099] Specifically, the pressure-bearing joint 15 includes:

[0100] a pressure-bearing housing 21 , the pressure-bearing housing 21 comprising a first portion connected to the rubber hose assembly and a second portion connected to the third rubber hose 29 ;

[0101] A support block 22, wherein a through hole is provided on the support block 22 for allowing the first traction rope 11 to pass through;

[0102] The limiting device 23 is used to fix the position of the first traction rope 11, preventing it from axially moving relative to the through-hole. The pressure-bearing housing 21 is fixed and sealed by fasteners. The through-hole and the limiting device 23 primarily function to limit the movement of the first traction rope 11 and transmit the force exerted on the first traction rope 11 to the pressure-bearing housing 21.

[0103] The operation steps of the water intake device of this embodiment are as follows:

[0104] Lower the water intake pipe 1, connect the crane 24 and the third counterweight 25, and then connect the water intake pipe 1 and the third counterweight 25. Operate the crane 24 to lift the third counterweight 25 outboard and lower it. Simultaneously, operate the lifting device 2 to lower the water intake pipe 1, controlling the relative speed so that the weight of the counterweight is always borne by the crane 24. Once the pressure-bearing joint 15 is in place, stop the lifting device 2. Operate the crane 24 to transfer the weight to the first traction rope 11 of the water intake pipe 1. Engage the brakes and begin water intake.

[0105] Recover and store: Operate the crane 24 to recover the third counterweight 25, and operate the lifting device 2 to recover the water intake pipe 1. During this process, control the relative speed so that the weight of the third counterweight 25 is always borne by the crane 24; operate the crane 24 to lift the third counterweight 25 to the deck storage position. Cancel the connection between the crane 24 and the third counterweight 25, and fasten the third counterweight 25 and the crane 24 to complete the recovery and storage.
