DETAILED DESCRIPTION

[0032] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.

[0033] The specific implementation of the present application is described in detail below with reference to specific embodiments.

[0034] Reference Figures 1-8 A multifunctional single-point mooring chain stopper for a ship includes:

[0035] The chain stopper base 11 is welded to the deck 1, and the chain guide wheel 12 is rotatably connected to the chain stopper base 11, and the guide groove 121 is formed in the chain guide wheel 12;

[0036] The stop assembly 2 is rotatably connected to the chain stopper base 11, and is used to brake the anchor chain 131;

[0037] The distance adjusting assembly 3 is slidably connected to the surface of the stop assembly 2, and is used to adjust the distance between the stop assembly 2 and the anchor chain 131;

[0038] The pinning assembly 4 is clamped and connected to the inside of one end of the stop assembly 2, and is used to fix the stop assembly 2;

[0039] The speed reduction assembly 5 is slidably connected to the side surface of the stop assembly 2, and is used to reduce the vibration caused by the stop assembly 2 when the anchor chain 131 is closed.

[0040] In an embodiment of the present application, as shown in Figure 2 and Figure 4 The stop assembly 2 includes:

[0041] The first support 21 is fixed to one side of the chain stopper base 11;

[0042] The chain stopper 22 is rotatably connected in the first support 21 and has an operating handle 23 connected at one end.

[0043] In the embodiment, the deck 1 is provided with a hawse pipe 13, and the anchor chain 131 is slidably connected at one end in the hawse pipe 13 and at the other end on the surface of the guide groove 121. The upper end of the anchor chain 131 is connected to an anchor winch, and the other end is connected to an anchor claw, and the hawse pipe 13 serves as a passage for the anchor chain 131, ensuring smooth operation of the anchor chain 131 during anchoring and unanchoring and avoiding collision with other structures.

[0044] During anchoring, the operating handle 23 is pressed downward to drive the chain stopper 22 to rotate upward on the first support 21, so that the chain stopper 22 is opened to release the anchor chain 131, and the anchor claw is slowly lowered into the water using the anchor winch. After the anchor claw reaches the bottom of the water, anchoring is stopped. After anchoring is completed, the chain stopper 22 is immediately closed to clamp the anchor chain 131 and prevent the anchor chain 131 from sliding.

[0045] During unanchoring, the chain stopper 22 is opened to release the anchor chain 131, the anchor winch is started, and the anchor chain 131 is slowly retracted. After unanchoring is completed, the chain stopper is closed.

[0046] In one embodiment of the present application, as shown in Figure 5 and Figure 6 the distance adjusting assembly 3 comprises:

[0047] The L-shaped stopper 31 is slidably connected to the surface of the chain stopper 22, and inclined grooves 32 are formed on both sides of the L-shaped stopper 31.

[0048] The extension seat 33 is fixed at the end of the L-shaped stopper 31, and a through hole 36 is formed in the interior of the extension seat 33.

[0049] The heat conducting frame 34 is fixed to the upper surface of the chain stopper 22, and the extension seat 33 is slidably connected to the surface of the heat conducting frame 34.

[0050] The latch hole 35 is formed in the heat conducting frame 34, and the heat conducting frame 34 and the through hole 36 are intermittently connected. The heat conducting frame 34 and the through hole 36 are internally clamped and connected with the pin 37.

[0051] In the embodiment, the surface of the chain stopper 22 is fixed with the heat conducting frame 34. When the chain stopper 22 generates a certain amount of heat due to frequent high load, the heat conducting frame 34 can efficiently dissipate heat from the chain stopper 22.

[0052] During long-term use, the contact position of the anchor chain 131 and the chain brake vane 22 is gradually worn due to friction, seawater corrosion and the like, so that the gap between the two is increased, and the ship may appear to walk the anchor. When it is observed that the gap between the anchor chain 131 and the chain brake vane 22 is increased, the pin 37 is removed from the bolt hole 35 and the through hole 36 by rotating the pin 37, and then the L-shaped stop block 31 is slid on the surface of the chain brake vane 22, so that the inclined groove 32 on the surface of the L-shaped stop block 31 is again closely fitted with the anchor chain 131, and finally the pin 37 is fixed in the bolt hole 35 and the through hole 36, so as to realize the positioning of the L-shaped stop block 31 on the chain brake vane 22. By sliding the L-shaped stop block 31 on the surface of the chain brake vane 22, the inclined groove 32 on the side surface of the L-shaped stop block 31 is always closely fitted with the anchor chain 131, so as to realize the effective braking of the anchor chain 131.

[0053] As shown in Figure 6 , the two sides of the L-shaped stop block 31 are provided with inclined grooves 32. When the inclined groove 32 on one side of the L-shaped stop block 31 is deformed due to long-term contact and friction with the anchor chain 131, the pin 37 can be loosened, and the L-shaped stop block 31 can be turned on the chain brake vane 22, so that the inclined groove 32 on the other side of the L-shaped stop block 31 can be in contact with the anchor chain 131, thereby braking the anchor chain 131, so that the inclined grooves 32 on both sides of the L-shaped stop block 31 can be utilized, thereby improving the utilization rate of the L-shaped stop block 31.

[0054] In an embodiment of the present application, as shown in Figure 4 , the pin fixing assembly 4 comprises:

[0055] The second support 41 is fixed on the side of the chain brake seat 11 away from the first support 21, and the end of the chain brake vane 22 is clamped and connected in the second support 41;

[0056] The sliding pin 42 is slidingly connected in the second support 41 and the end of the chain brake vane 22, and the end of the sliding pin 42 is vertically connected with the handle 43, and the handle 43 and the second support 41 are connected by the spring 46;

[0057] The handle groove 44 is provided on the inner wall of the second support 41, and the end of the handle 43 is slidingly connected in the handle groove 44;

[0058] The arc-shaped groove 45 is provided on the inner side of the second support 41 and is in communication with the end of the handle groove 44, and the handle 43 is rotatably connected in the arc-shaped groove 45;

[0059] The end frame 47 is fixed on the end of the second support 41 and is clamped and connected between the inner wall and the handle 43.

[0060] In the embodiment, when the pawl 22 is opened, first push the handle 43 to the spring 46 direction, so that the handle 43 slides in the handle groove 44, until the handle 43 is completely slid into the arc-shaped groove 45, when the handle 43 slides into the arc-shaped groove 45, rotate the handle 43, so that the handle 43 is turned 180 degrees in the arc-shaped groove 45, until the handle 43 is turned out of the arc-shaped groove 45, at this time, the handle 43 will be pulled by the spring 46 to slide the sliding pin 42 in the second support 41 and the pawl 22 reversely, until the end of the handle 43 slides to contact the inner wall of the end frame 47, the handle 43 will pull the sliding pin 42 at the other end to slide out of the end of the pawl 22, so that the pawl 22 can be opened.

[0061] When the pawl 22 is closed, and the pawl 22 needs to be fixed, first push the handle 43 inward, so that the handle 43 drives the sliding pin 42 to slide in the second support 41 to the pawl 22 direction, until the sliding pin 42 slides to the end of the pawl 22, so that the pawl 22 can position the sliding pin 42, when the handle 43 slides to the side of the arc-shaped groove 45, rotate the handle 43, so that the end of the handle 43 is rotated to the inside of the arc-shaped groove 45, because the arc-shaped groove 45 and the handle groove 44 are communicated, so release the handle 43, the handle 43 will be pushed by the spring 46 to slide to the inside of the handle groove 44 (as Figure 4 , so that the sliding pin 42 is limited by the handle 43 and the handle groove 44, which improves the stability of the sliding pin 42 fixing the pawl 22 in the closed state.

[0062] In an embodiment of the application, as shown in Figure 7 and Figure 8 , the speed reduction assembly 5 comprises:

[0063] The speed reduction block 51 is slidingly connected in the inside of the pawl 22, and the end is connected with the inner wall of the pawl 22 through the compression spring 57;

[0064] The oil chamber 53 is fixed in the inside of the pawl 22, and the inside is slidingly connected with the piston 56, and the piston 56 is provided with the flow channel 561;

[0065] The embedded groove 52 is provided in the side of the pawl 22, and the inside is slidingly connected with the sliding rod 54, and the end of the sliding rod 54 is connected with the side of the piston 56;

[0066] The connecting rod 55 is hingedly connected with the side of the speed reduction block 51 at one end, and hingedly connected with the end of the sliding rod 54 at the other end.

[0067] In this embodiment, when the chain brake 22 is closed, the chain brake 22 will first contact the anchor chain 131 with the undersides of the deceleration block 51, and the deceleration block 51 will slide to the inside of the chain brake 22 under the impact of the anchor chain 131, so that the deceleration block 51 compresses the compression spring 57 at the upper end. When the deceleration block 51 slides, it will push the sliding rod 54 to slide in the embedded groove 52 through the connecting rod 55, and the sliding rod 54 will push the piston 56 to slide in the oil chamber 53. During the sliding of the piston 56 in the oil chamber 53, the hydraulic oil inside the oil chamber 53 will flow through the flow channel 561, so as to slow down the rapid sliding of the compression spring 57. When the chain brake 22 is closed, through the prior contact of the deceleration block 51 and the anchor chain 131 and the damping effect of the hydraulic oil, the energy of the anchor chain 131 during movement can be absorbed and consumed, the impact force and vibration of the anchor chain 131 are reduced, the impact on the chain brake is reduced, and the danger caused by the closing of the anchor chain 131 at high speed (such as the anchor in the torrent) is slowed down.

[0068] In one embodiment of the present application, as shown in Figure 1 and Figure 2 The side surface of the chain brake seat 11 is connected with a water flushing assembly 6, which is located on the upper side of the anchor chain barrel 13, and is used to flush the anchor chain 131 inside the anchor chain barrel 13. The water flushing assembly 6 comprises:

[0069] An arc-shaped pipe 61 is fixed on the chain brake seat 11, and at least two groups of spray heads 62 are connected on the side surface of the arc-shaped pipe 61;

[0070] An anchor chain pipe 63 is connected on the outer side of the chain brake seat 11, one end of which is communicated with the arc-shaped pipe 61, and the other end is communicated with the output end of a self-priming pump, and the end of the self-priming pump away from the arc-shaped pipe 61 is communicated with the water bottom through a water suction pipe.

[0071] In this embodiment, when the anchor is lifted, the self-priming pump is started, so that the self-priming pump can guide the anchor chain water into the arc-shaped pipe 61 through the anchor chain pipe 63, and spray it out through the spray heads 62 at the bottom of the arc-shaped pipe 61, so as to flush the anchor chain 131 in the anchor chain barrel 13 when the anchor is lifted, reduce the accumulation of impurities on the surface of the anchor chain 131, and prevent seawater erosion.

[0072] The working principle of the present application is that when the anchor is lifted, the chain stopper gate 22 is opened, the anchor chain 131 is released, the anchor winch is started, the anchor chain 131 is slowly wound up, and after the anchor is lifted, the chain stopper gate is closed. When the chain stopper gate 22 is closed, the chain stopper gate 22 drives the speed reduction block 51 to contact the anchor chain 131, and the speed reduction block 51 slides to the inside of the chain stopper gate 22 under the impact of the anchor chain 131, so that the speed reduction block 51 compresses the compression spring 57 at the upper end. When the speed reduction block 51 slides, it will push the sliding rod 54 to slide in the embedded groove 52 through the connecting rod 55, and the sliding rod 54 will push the piston 56 to slide in the oil chamber 53. During the sliding of the piston 56 in the oil chamber 53, the hydraulic oil in the oil chamber 53 will flow through the flow channel 561, which can slow down the rapid sliding of the compression spring 57. Through the damping effect of the hydraulic oil, the energy of the anchor chain 131 in the movement process can be absorbed and consumed, the impact force and vibration of the anchor chain 131 can be reduced, the impact on the chain stopper can be reduced, and the danger caused by the closing of the chain stopper when the anchor chain 131 slides out at high speed can be reduced.

[0073] In the description of the present application, it should be pointed out that unless otherwise specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected or can communicate with each other; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the communication between two elements or the interaction between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0074] The above is only the preferred embodiment of the present application, and does not limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
