Description
Technical Field
[0001] The utility model relates to the technical field of ship auxiliary equipment, in particular to a device for measuring the release length of a ship's anchor chain. Background Art
[0002] When a ship performs an anchor dropping / retrieving operation, it is necessary to observe and identify the release length of the anchor chain. Currently, a special mark is mostly made on the link of the anchor chain to identify the release length of the anchor chain. For example, paint is applied to the anchor chain, and a stainless steel ring is installed on the anchor chain, and then the bridge command personnel are reported through a handheld communication device.
[0003] The existing methods for identifying the release length of the anchor chain have the following technical problems: When the anchor chain is in use, collisions and frictions occur between the links, and collisions and frictions also occur between the anchor chain and the bulkhead, the anchor sprocket, and the seabed sand and gravel. In addition, due to the corrosion of seawater and the covering of sediment, the paint on the link is easily worn and disappeared, and even the stainless steel ring may break and be lost. Therefore, when performing an anchor dropping or retrieving operation, it is easy for the ship's anchor dropping operator to inaccurately observe the release length of the released anchor chain; when performing an anchor retrieving and dropping operation, the noise at the bow anchor winch operation site is relatively large, and it is easy for the handheld communication device to report information with unclear information transmission and inconsistent information. The above technical problems may all cause the bridge command personnel to obtain incorrect information about the release length of the anchor chain, which may lead to incorrect decisions and result in safety accidents such as anchor chain breakage, dragging anchor, and losing the anchor. The bridge command personnel cannot timely and effectively master the information at the bow anchor dropping / retrieving operation site, and need to repeatedly confirm through a handheld communication device, with low efficiency, long anchor dropping / retrieving time, resulting in increased fuel consumption, increased carbon emissions, and increased ship transportation costs.

[0034] The utility model provides a device for measuring the releasing length of a ship's anchor chain, which comprises an anchor winch 2 and a guiding mechanism 3 arranged on a ship deck 1. The anchor chain output by the anchor winch 2 enters an anchor chain barrel 4 on the ship deck 1 after being guided by the guiding mechanism 3. The device for measuring the releasing length of the ship's anchor chain further comprises a length measuring mechanism 5. The length measuring mechanism 5 is installed on the ship deck 1 near the guiding mechanism 3, and is located between the anchor winch 2 and the guiding mechanism 3. The length measuring mechanism 5 includes: a base 51, the top end face of the base 51 is provided with a first strip-shaped groove 511 for the anchor chain to pass through, the bottom of the first strip-shaped groove 511 is provided with a second strip-shaped groove 512, the opposite ends of the first strip-shaped groove 511 respectively penetrate through the opposite side faces in the length direction of the base 51, and the opposite ends of the second strip-shaped groove 512 also penetrate through the opposite side faces in the length direction of the base 51; a pressing plate 52, the pressing plate 52 has a connecting end and a movable end, the connecting end is rotatably installed at the top of one end of the first strip-shaped groove 511 close to the guiding mechanism 3, the movable end extends towards the end of the first strip-shaped groove 511 away from the guiding mechanism 3, the opposite ends of the lower surface of the pressing plate 52 in its width direction are respectively provided with pressing strips 521, the bottoms of the pressing strips 521 are arranged parallel to the bottom of the first strip-shaped groove 511, the pressing strips 521 extend along the length direction of the pressing plate 52, two parts of the bottom of the first strip-shaped groove 511 located on the opposite sides of the second strip-shaped groove 512 respectively cooperate with the two pressing strips 521, and a preset gap is left between the pressing strips 521 and the connecting end below the pressing plate 52; a length measuring wheel 53, the length measuring wheel 53 is rotatably arranged below the pressing plate 52 through a rotating shaft, a certain frictional force is provided between the length measuring wheel 53 and the outer circumference of the rotating shaft, the bottom of the first strip-shaped groove 511 cooperates with the outer peripheral surface of the length measuring wheel 53, the length measuring wheel 53 is connected with a counter 531, the counter 531 is electrically connected with the ship's bridge, and the length measuring wheel 53 is arranged in the preset gap between one pressing strip 521 and the connecting end; a driving member 54, the driving member 54 is arranged on the side face of the base 51, the driving member 54 drives the pressing plate 52 to rotate around its connecting end, and the driving member 54 is elastically connected with the pressing plate 52.
[0035] In the technical solution proposed by this application, before the anchor chain output by the windlass 2 enters the hawsepipe 4 through the guiding mechanism 3, it first passes through the length measuring mechanism 5. When passing through the length measuring mechanism 5, one of the adjacent two links in the anchor chain enters the second strip-shaped groove 512 and moves along the second strip-shaped groove 512 in the direction close to the guiding mechanism 3. The relative two ends in the width direction of the other one of the adjacent two links in the anchor chain respectively enter between the bottom of the first strip-shaped groove 511 and the two pressing strips 521 and move in the direction close to the guiding mechanism 3. Since the driving member 54 is elastically connected to the pressing plate 52, the link cooperating with the pressing strip 521 will basically not shake up and down after being elastically squeezed by the first strip-shaped groove 511 and the pressing strip 521. After the link cooperating with the pressing strip 521 is elastically squeezed, one end in the width direction of this part of the link will move to the lower part of the distance measuring wheel 53. Under the frictional force of the link, the distance measuring wheel 53 will rotate, and the counter 531 will display the traveled distance according to the number of turns of the distance measuring wheel 53. By processing the number displayed by the counter 531, the released length of the anchor chain can be calculated; the length measuring mechanism 5 is installed on the ship deck 1 near the guiding mechanism 3 and is located between the windlass 2 and the guiding mechanism 3, which can reduce the up-and-down shaking degree of the anchor chain before entering the length measuring mechanism 5.
[0036] It should be noted that the hawsepipe 4 is the main passage for the anchor chain to enter the sea through the deck 1. It is a vertical pipe, and the anchor chain enters and exits the hull through this pipe. The guiding mechanism 3 can be a guiding roller, which is located near the top of the hawsepipe 4 and is used to guide the anchor chain in and out of the hawsepipe 4. The guiding roller helps to reduce the friction between the anchor chain and the hawsepipe 4 and ensures that the anchor chain moves in the normal direction. It can be understood that the smaller the up-and-down shaking amplitude of the part of the anchor chain closer to the guiding roller.
[0037] It also should be noted that the distance measuring wheel 53 is a simple tool for measuring distance. It usually consists of a graduated wheel body and a handle. When in use, the user pushes the handle to make the wheel body roll along the ground, and the counter 531 will display the traveled distance according to the number of turns of the wheel body. Generally, the distance measuring wheel 53 cannot directly measure the anchor chain in the working state on the ship. The main reason is that the weight of the anchor chain is large and it shakes up and down. In this application, for the convenience of reading, the number read by the counter 531 can be transmitted to the display screen on the bridge by wireless transmission. It should be noted that the value read by the counter 531 multiplied by two is the relatively accurate released length of the anchor chain.
[0038] In actual work, the anchor chain between the anchor windlass 2 and the guiding mechanism 3 slopes downward from the anchor windlass 2 to the guiding mechanism 3. To facilitate the entry of the anchor chain into the length measuring mechanism 5, as a preferred embodiment, a further improvement of the present utility model lies in that the bottom of the first strip-shaped groove 511 slopes downward from the end close to the anchor windlass 2 to the end close to the guiding mechanism 3, and the bottom of the second strip-shaped groove 512 and the bottom of the first strip-shaped groove 511 have the same inclination direction and inclination angle.
[0039] It can be understood that the anchor chain between the anchor windlass 2 and the guiding mechanism 3 will sag under the action of its own gravity. To facilitate the entry of the anchor chain, the inclination angle of the bottom of the first strip-shaped groove 511 can be set according to the approximate inclination angle of this section of the anchor chain.
[0040] To facilitate the entry of the anchor chain between the bottom of the first strip-shaped groove 511 and the pressing strip 521, as a preferred embodiment, a further improvement of the present utility model lies in that a first arc-shaped corner 5211 is provided at the bottom of the end of the pressing strip 521 away from the connection end, and a second arc-shaped corner 5111 is provided at the bottom of the end of the first strip-shaped groove 511 away from the connection end, and the second arc-shaped corner 5111 is located below the first arc-shaped corner 5211. The cooperation of the first arc-shaped corner 5211 and the second arc-shaped corner 5111 increases the opening between the bottom of the first strip-shaped groove 511 and the pressing strip 521, facilitating the smooth entry of the anchor chain.
[0041] To better limit the anchor chain entering the second strip-shaped groove 512, a third strip-shaped groove 522 is provided on the lower surface of the pressing plate 52. The third strip-shaped groove 522 extends along the length direction of the pressing plate 52. The third strip-shaped groove 522 cooperates with the second strip-shaped groove 512. The bottom of the third strip-shaped groove 522 is arranged in parallel with the bottom of the second strip-shaped groove 512, and the second strip-shaped groove 512 is located directly below the third strip-shaped groove 522. The addition of the third strip-shaped groove 522 makes the anchor chain entry port of the length measuring mechanism 5 approximately cross-shaped, and the cross-shaped entry port can surely limit the entering anchor chain better.
[0042] To adjust the elastic extrusion force between the pressing strip 521 and the anchor chain, a further improvement of the present utility model lies in that the driving member 54 includes: a gear 541, the gear 541 is rotatably arranged on the side surface of the base 51; a rack 542, the bottom of the rack 542 meshes with the gear 541, a waist-shaped hole 5421 is provided along the length direction of the rack 542, a positioning member 544 is arranged in the waist-shaped hole 5421, and the rack 542 is slidably arranged on the side surface of the base 51 through the positioning member 544; an elastic member 543, the elastic member 543 is hinged between the top of the rack 542 and the pressing plate 52.
[0043] When it is necessary to increase the elastic extrusion force between the pressing strip 521 and the anchor chain, the gear 541 rotates counterclockwise by a certain angle. Driven by the gear 541, the rack 542 moves downward. Driven by the rack 542, the movable end of the pressing plate 52 rotates counterclockwise by a certain angle. When it is necessary to reduce the elastic extrusion force between the pressing strip 521 and the anchor chain, the gear 541 rotates clockwise by a certain angle. Driven by the gear 541, the rack 542 moves upward. Driven by the rack 542, the movable end of the pressing plate 52 rotates clockwise by a certain angle.
[0044] The elastic member 543 itself belongs to the category of the prior art and can be a spring or a shock absorber.
[0045] The driving member 54 further includes a driving motor which is arranged inside the base 51 and is drivingly connected to the gear 541. The side plate of the base 51 is provided with an installation through hole, and the installation through hole is detachably installed with an installation plate. The rotating shaft of the driving motor penetrates through the installation plate and is rotatably connected to the installation plate.
[0046] Installing the driving motor inside the base 51 can protect the base 51, and the arrangement of the installation plate and the installation through hole facilitates the maintenance of the driving motor.
[0047] The above are only the preferred embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structural transformation made by using the content of the specification and drawings of the present application under the inventive concept of the present application, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
