Description

Technical Field

[0001] This invention relates to the field of marine technology, and in particular to a cable guide hole structure with a closing function. Background Technology

[0002] A guide hole, also known as a bulwark guide hole, is a perforated guide hole located on the bulwark. It is a circular or elliptical annular casting. Guide holes are usually made of cast iron or cast steel, installed on the bulwark, guide cables through the hull, and prevent cables from damaging the hull.

[0003] The cable guide hole on a ship is used when the ship needs to moor at the shore, and a hole needs to be reserved in the middle to facilitate the casting of the cable.

[0004] Some ships have low mooring decks (such as passenger ships), and to prevent waves from hitting the mooring deck, a wave shield is usually added above the mooring deck. However, the cable exit hole of the cable guide is not immune to wave impact.

[0005] The current guide hole design has the following disadvantages when the mooring deck is relatively low above the waterline:

[0006] 1. When the wind and waves are high, the rising waves are detrimental to the safety of crew members in this area;

[0007] 2. The mooring area is always filled with water, which makes the ship's equipment susceptible to damage;

[0008] 3. The ship's exterior is incomplete, which is detrimental to its aesthetics. Summary of the Invention

[0009] The technical problem to be solved by the present invention is to overcome the above-mentioned defects in the prior art and provide a cable guide hole structure with a closing function.

[0010] The present invention solves the above-mentioned technical problems through the following technical solution:

[0011] A cable guide hole structure with a closing function includes a cable guide hole body; the cable guide hole body is provided with cable holes for cable passage, the cable holes being distributed along the front-back direction of the cable guide hole body; the cable guide hole body is provided with a strip-shaped groove that can divide the entire inner cavity of the cable hole into front and back parts; the strip-shaped groove is distributed along the left-right direction of the cable guide hole body; a partition that can seal the cable hole is provided in the strip-shaped groove, and the partition and the cable guide hole body are detachably connected.

[0012] Furthermore, one end of the strip groove is an open end for the partition to enter and exit the strip groove.

[0013] Furthermore, the partition has a detachable fastener at one end of the strip-shaped groove on the side of the opening end, which can secure the partition to the cable guide hole body.

[0014] Furthermore, the detachable fastener is a strong electromagnetic suction plate.

[0015] Furthermore, the width of the strip groove is 8–10 mm.

[0016] Furthermore, the length direction of the strip groove is perpendicular to the central axis of the cable hole.

[0017] Furthermore, the top of the partition is not higher than the top of the cable guide hole body; the side of the partition does not exceed the side of the cable guide hole.

[0018] Furthermore, the cable guide hole structure with closure function also includes a perforated plate that can be inserted into the strip groove, and the perforated plate has a cable outlet hole in the middle that allows the cable hole to pass through when the perforated plate is inserted into the strip groove to replace the partition.

[0019] Furthermore, the perforated plate has a detachable connector at one end of the opening end of the strip groove that can secure the perforated plate to the cable guide hole body.

[0020] Furthermore, a drag-reducing pad is fixed to the wall of the rope outlet hole.

[0021] The beneficial effects of this invention are as follows: It prevents water from splashing onto the ship, ensuring the cleanliness of the ship's deck and the safety of crew members in the mooring area; since there is no water in the mooring area, it reduces wear and tear on ship equipment; it also optimizes the ship's appearance and improves its aesthetics. The bulkhead in this invention is replaceable, extending the service life of the guide wire holes. When the ship is in a moored state, this invention reduces wear on the mooring lines, extending their service life. This invention is easy to manufacture, has low manufacturing costs, and has good application prospects. Attached Figure Description

[0028] The present invention will be described more clearly and completely below with reference to a preferred embodiment and the accompanying drawings.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a cable guide hole structure with a closing function includes a cable guide hole body 10; the cable guide hole body 10 is provided with cable holes 11 for cable passage, and the cable holes 11 are distributed along the front and rear direction of the cable guide hole body.

[0030] The cable guide hole body 10 has a strip groove 20 that divides the entire inner cavity of the cable hole into two parts, front and back. The strip groove 20 is distributed along the left and right direction of the cable guide hole body 10.

[0031] The width D of the groove 20 is 8-10 mm. The length direction of the groove 20 is perpendicular to the central axis of the cable hole 11.

[0032] The inner diameter of the cable hole gradually decreases from both ends towards the middle, meaning the cable hole is wider at both ends and narrower in the middle. The connection point between the strip groove 20 and the cable hole 11 is where the inner diameter of the cable hole is at its minimum.

[0033] The strip groove 20 is provided with a partition 30 that can seal the cable hole, and the partition 30 and the cable guide hole body 10 are detachably connected.

[0034] The top of the partition 30 is not higher than the top of the cable guide hole body; the side of the partition 30 does not exceed the side of the cable guide hole.

[0035] One end of the strip groove 20 is an open end for the partition to enter and exit the strip groove; the other end of the strip groove 20 is a closed end.

[0036] The partition 30 has a detachable fastener at one end of the strip-shaped groove, which can secure the partition to the cable guide hole body. In this embodiment, the detachable fastener 31 is a strong electromagnetic suction plate.

[0037] like Figure 5 and Figure 6 As shown, the cable guide hole structure with closure function also includes a perforated plate 40 that can be inserted into the strip groove. The perforated plate 40 has a cable outlet hole 41 in the middle that allows the cable hole to pass through when the perforated plate is inserted into the strip groove to replace the partition.

[0038] Figure 6 This is a top view of a perforated plate inserted into a slot.

[0039] The perforated plate 40 has a detachable connector 42 at one end of the strip groove, which can fix the perforated plate to the cable guide hole body. In this embodiment, the detachable connector 42 is a strong electromagnetic suction plate. The wall of the rope outlet hole 41 is fixedly provided with a drag-reducing pad 43.

[0040] In this embodiment, the cable guide hole structure with closure function includes a cable guide hole body, a partition, and a perforated plate. The perforated plate can replace the partition and is inserted into the strip groove of the cable guide hole body.

[0041] When the cable guide hole body and the partition are combined, the device is in its non-cable state; when the cable guide hole body and the perforated plate are combined, the device is in its cable state.

[0042] When the device is in a non-moored state, the guide hole body and the bulkhead are combined. The bulkhead is inserted into the strip-shaped groove of the guide hole body, sealing the cable hole. The strong electromagnetic suction plate at the end of the bulkhead, after being energized, firmly attaches to the guide hole body, thus fixing the bulkhead and the guide hole body together. The shape of the bulkhead is consistent with that of the guide hole body. When the device is in a non-moored state, the cable hole is closed by the bulkhead, preventing waves from entering the ship's deck through the cable hole.

[0043] When this device requires cable connection, it can be switched from a non-cabled state to a cabled state. The process is as follows: turn off the switch of the strong electromagnetic chuck at the end of the partition and remove the partition; then insert the perforated plate into the slot. After the strong electromagnetic chuck on the perforated plate is energized, it firmly attaches to the cable guide hole body, and the perforated plate and the cable guide hole body are fixedly connected. The shape of the perforated plate is consistent with that of the cable guide hole body, and the rope outlet hole of the perforated plate is consistent with the cable hole of the cable guide hole body. The drag-reducing pad on the wall of the rope outlet hole can reduce the resistance when the cable passes through. When the device is in the cabled state, the cable can pass normally through the cable hole of the cable guide hole body.

[0044] This invention can prevent waves from rising, ensuring the cleanliness of the ship's deck and the safety of crew members in the mooring area; since there is no water in the mooring area, it can reduce the wear and tear on ship equipment; it also optimizes the ship's appearance and improves its aesthetics.

[0045] The partition in this invention is replaceable, which extends the service life of the cable guide hole.

[0046] When the present invention is in a cabled state, it can reduce cable wear and extend the cable's service life.

[0047] This invention is easy to manufacture, has low manufacturing cost, and has good application prospects.

[0048] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
