Description

Technical Field

[0001] The utility model mainly relates to the technical field of marine equipment, in particular to a controllable ship navigation hole. Background Art

[0002] In the field of shipbuilding and operation, navigation holes serve as important observation and communication windows on ships. Their design and performance are directly related to the safety and practicality of the ship. Traditional ship navigation holes are often fixed in design, unable to achieve flexible opening and closing control. This not only limits the adaptability of the ship in different environments, but also increases safety risks.

[0003] Furthermore, existing ship navigation apertures often have a single design, making them difficult to adapt to the needs of different ship types and navigation equipment, limiting their application. Furthermore, regarding safety, some devices have sharp edges or unstable structures, increasing the risks involved in use. Therefore, it is necessary to develop a new, controllable ship navigation aperture. Utility Model Content

[0004] To address the deficiencies of the prior art, the present invention provides a controllable ship navigation hole, which is achieved through the following technical solutions:

[0005] A controllable ship navigation hole comprises a base, a through hole is provided in the center of the base, a U-shaped base is fixedly mounted on the bottom surface of the base, a through groove is provided at the bottom of the inner wall of the through hole, a movable block is movably mounted in the through groove, a hydraulic cylinder is fixedly mounted on the top surface of the inner wall of the U-shaped base, and the movable end of the telescopic rod of the hydraulic cylinder is fixedly connected to the bottom surface of the movable block.

[0006] Furthermore, the through hole is a rectangular hole, and the edges of the base and the through hole are rounded.

[0007] Furthermore, baffles are fixedly installed on both sides of the bottom surface of the moving block, and the baffles are respectively slidably matched with the side opposite to the through groove.

[0008] Furthermore, reinforcing ribs are fixedly installed on both sides and the top of the base.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] 1. This device can drive the moving block to move up and down in the through-hole through the telescopic movement of the hydraulic cylinder, thereby effectively controlling the opening area of ​​the through-hole. When in use, the cable can be clamped through the mutual cooperation between the moving block and the inner wall of the through-hole. This design not only improves the convenience of operation, but also ensures the accuracy of control, making the opening and closing of the guide hole more flexible and meeting the needs of different usage scenarios.

[0011] 2. By rounding the edges of the through-holes and slots, sharp edges are prevented from abrading the moving parts, while improving overall safety. Furthermore, the baffle design ensures the stable sliding of the moving block within the slot, preventing deviation during movement, further improving safety. It also prevents the cable from slipping into the slot, preventing it from getting stuck, and improving the reliability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that such equivalent forms also fall within the scope defined in this application.

[0017] Example: A controllable ship navigation hole

[0018] like Figure 1-3 As shown, a controllable ship navigation hole, its specific structure includes:

[0019] The base body 1 has a through hole 2 at its center, and a U-shaped base 3 is fixedly mounted on the bottom surface of the base body 1. This design enhances the stability of the overall structure. A through groove 4 is provided at the bottom of the inner wall of the through hole 2. The design of the through groove allows for flexible operation of internal components. The edges of the through groove 4 are rounded to avoid wear of the moving parts by sharp edges, while improving overall safety. A moving block 5 is movably mounted in the through groove 4. The opening and closing of the through hole 2 can be controlled by the displacement of the moving block 5, thereby achieving flexible control of the guide hole. A hydraulic cylinder 6 is fixedly mounted on the top surface of the inner wall of the U-shaped base 3. The hydraulic cylinder 6 serves as a power source, and the movable end of its telescopic rod is fixedly connected to the bottom surface of the moving block 5. The telescopic movement of the hydraulic cylinder 6 drives the moving block 5 to move up and down in the through groove 4, thereby achieving effective control of the guide hole. This design not only improves the convenience of operation, but also ensures the accuracy of control.

[0020] The through hole 2 is a rectangular hole, which is designed to match rectangular navigation devices and improve installation compatibility. The edges of the base 1 and through hole 2 are rounded. This detailed design not only improves the appearance but also reduces accidental injuries caused by sharp edges during use, thereby enhancing safety.

[0021] Baffles 7 are fixedly mounted on both sides of the bottom surface of the movable block 5. This design ensures stable sliding of the movable block 5 within the through-groove 4 and prevents deviation during movement. The baffles 7 slide in engagement with the opposite side of the through-groove 4. This sliding engagement not only ensures smooth movement of the movable block 5, but also improves the durability of the structure and extends its service life.

[0022] Reinforcing ribs 8 are fixedly mounted on both sides and the top of the base 1. The addition of these ribs significantly enhances the structural strength of the base 1, enabling it to withstand greater external forces and improving its overall stability and durability. This design ensures the stability and reliability of the navigation hole during long-term use and reduces repair costs due to structural damage.

[0023] In the interpretation of the present invention, it should be noted that the terms indicating orientation are only for the convenience of description and understanding, and are not the only limitation on the installation position of specific technical features, and do not exclude other possible installation methods.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
