Description

Technical Field

[0001] The utility model relates to the field of shipbuilding, in particular to a deformation-resistant cab window structure. Background Art

[0002] With the development trend of renewable energy, the offshore wind power industry has completed a large number of production and application layouts in recent years. The operation and maintenance of offshore wind farms are crucial. As a mobile link between wind farms and land, wind power operation and maintenance ships provide guarantees for the daily operation, supply and maintenance of wind farms, and minimize and reduce operation and maintenance time and costs.

[0003] Mainstream high-end maintenance ship projects are usually equipped with helicopter platforms, relying on the good maneuverability and fast response speed of helicopters to complete emergency repairs and emergency rescue services during non-window periods. The compact maintenance ship type prompts the helicopter platform to be arranged above the cab through connecting supports, and the load force during helicopter takeoff and landing will be transmitted to the cab structure to generate huge vertical and lateral forces. Based on the requirements of cab sight, large-sized windows are set on the walls around the cab. The helicopter platform itself cannot decompose the transmission of load force by adding columns. Moreover, the effect of improving relative deformation through structural reinforcement is very limited, and it will have a great impact on the weight control of the entire ship. Based on this situation, it is necessary to solve the problem of excessive load force during helicopter takeoff and landing through research and design of the structure of the cab window itself, and minimize the risk of damage to the cab window.

[0004] In document ZL 2024103494100, a window frame-free ship structure and a ship are disclosed, including: a hull structure, sealant and glass; the glass is correspondingly embedded in the hull structure; sealant is filled between the glass and the hull structure, and the glass can be bonded to the hull structure through the sealant. This structure is to apply sealant first, and then pass a rubber strip to prevent the sealant from overflowing. After long-term use of this structure, the rubber strip will be displaced and fall out of the glass and glue.

[0005] Therefore, a new technical solution is needed to solve the above technical problems. Summary of the invention

[0006] In order to solve the above problems, the utility model discloses a deformation-resistant cab window structure, which ensures the integrity of the cab window structure and prevents it from being damaged when subjected to a large external load.

[0007] The technical solution of the utility model is: an anti-deformation cab window structure, including glass located in the window, the glass is provided with surrounding Sika glue, a glass pressure plate and a sponge strip, gaps are provided between the window frames and the glass on both sides of the window, the gaps in the thickness direction of the window glass are filled with Sika glue and sponge strips, the Sika glue is located at the upper part of the sponge strip, the outer side of the Sika glue and the sponge strip is a glass pressure plate, and the lower part of the glass pressure plate located in the room is fixed on the window seat.

[0008] By adopting the above technical solution, the high-strength deformation resistance of the windows can be enhanced through Sika glue and sponge strips, ensuring the normal use of the windows under harsh working conditions.

[0009] Preferably, the gaps between the window frames and the glass on two sides of the four sides of the window are consistent on the left, right and top sides, and the gap on the bottom side is smaller than the gap on the top side.

[0010] By adopting the above technical solution, since the window glass itself has a large weight, the bottom has to bear the greatest pressure, so the gap at the bottom is smaller than the gap at other positions, reducing the deformation caused by the window itself.

[0011] Preferably, the bottom of the glass is perpendicular to the upper part of the rubber pad base, and two sides of the rubber pad base in the length direction are respectively abutted against the position between the glass pressure plate and the glass stop frame.

[0012] By adopting the above technical solution, when the helicopter takes off and lands, the rubber pad base can, to a certain extent, work together with the sponge strip and Sika glue to increase the overall deformation resistance of the window.

[0013] Preferably, the glass is located on the indoor side, the sponge strip is located between the glass pressure plate, the upper part of the rubber pad base and the glass, and the glass is located on the outdoor side, the sponge strip is located between the glass stop frame, the rubber pad base and the glass.

[0014] By adopting the above technical solution, the sponge strip is located on the side of the glass, which can prevent collision between the glass and the window seat and improve the overall deformation resistance of the window.

[0015] Preferably, the thickness of the sponge strip is greater than the size of the gap, and the Sika glue seals the sponge strip in the corresponding position.

[0016] By adopting the above technical solution, the sponge strip can be stuck in the gap. Since the thickness of the sponge strip is greater than the gap, the sponge strip can be tightly stuffed into the gap.

[0017] Preferably, a gap is provided between the rubber pad base at the bottom of the glass and the window seat, that is, there is no contact between the rubber pad base and the window seat.

[0018] By adopting the above technical solution, when a helicopter takes off and lands on the platform, there will be a downward force on the platform. When the downward load force on the window glass exceeds the load, the gap between the rubber pad base and the window seat of the window on the platform can accept the downward movement of the glass to a certain extent, thereby increasing the overall deformation load force of the window.

[0019] Preferably, the side of the glass pressing plate away from the sponge strip is fixed to the window seat by a cross recessed countersunk screw.

[0020] By adopting the technical solution and fixing the glass pressing plate on the window seat, the glass pressing plate can be conveniently used to press the sponge strip and the rubber pad base.

[0021] The benefits of the utility model are as follows: 1. The utility model arranges a sponge strip on the side of the glass. Above the sponge strip, when a helicopter takes off or lands, the glass will be displaced. The sponge can prevent collision between the glass and the window frame, reduce the probability of glass breakage, and improve the overall anti-deformation effect of the window.

[0022] 2. In the utility model, Sika glue is arranged between the glass and the glass pressing plate to firmly clamp the sponge strip between the glass, the rubber pad base and the glass pressing plate. The Sika glue can prevent the sponge strip from being displaced. When the glass is deformed, due to its relatively sticky property, the Sika glue can pull the glass back to its original position to a certain extent, thereby reducing the displacement caused by the deformation and the damage caused to the glass itself.

[0023] 3. The utility model provides a rubber pad base at the bottom of the glass. When the glass is downward, if the load exceeds the overall load, the gap between the rubber pad base and the window seat can compensate for the downward deformation of the glass to a certain extent, so as not to damage the glass.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] like Figure 1-4 As shown, a deformation-resistant cab window structure includes a glass 1 located in the window, the glass 1 is provided with surrounding Sika glue 2, a glass pressure plate 3 and a sponge strip 4, gaps are provided between the window frames 8 on both sides of the four sides of the window and the glass 1, the gaps in the thickness direction of the window glass are filled with Sika glue 2 and sponge strip 4, the Sika glue 2 is located at the upper part of the sponge strip 4, the outer side of the Sika glue 2 and the sponge strip 4 is the glass pressure plate 3, the lower part of the glass pressure plate 3 located indoors is fixed on the window seat 8, the Sika glue 2 and the sponge strip 4 are used to enhance the high-strength deformation resistance of the window, and ensure the normal use of the window under harsh working conditions.

[0031] The gaps between the window frames and the glass 1 on the four sides of the window are consistent on the left, right and top sides, and the gap on the bottom is smaller than the gap on the top side. Since the glass of the window itself has a large weight, the pressure on the bottom is the greatest, so the gap at the bottom is smaller than the gaps at other positions, reducing the deformation caused by the window itself.

[0032] The bottom of the glass 1 is perpendicular to the upper part of the rubber pad base 6, and the two sides of the rubber pad base 6 in the length direction are respectively abutted against the position between the glass pressure plate 7 and the glass stop frame. When the helicopter takes off and lands, the rubber pad base 6 can, to a certain extent, work together with the sponge strip 4 and the Sika glue 2 to increase the overall deformation resistance of the window.

[0033] The glass 1 is located on the indoor side, the sponge strip 4 is located between the glass pressure plate 3, the upper part of the rubber pad base 6 and the glass 1; the glass 1 is located on the outdoor side, the sponge strip 4 is located between the glass stop frame 7, the rubber pad base 6 and the glass 1. The sponge strip 4 is located on the side of the glass 1, which can prevent the glass 1 from colliding with the window seat and improve the overall deformation resistance of the window.

[0034] The thickness of the sponge strip 4 is greater than the size of the gap, and the Sika glue 2 seals the sponge strip 4 at the corresponding position so that the sponge strip 4 can be stuck in the gap. Since the thickness of the sponge strip 4 is greater than the gap, the sponge strip 4 can be tightly stuffed into the gap.

[0035] There is a gap between the rubber pad base 6 and the window seat 8 at the bottom of the glass 1, that is, there is no contact between the rubber pad base 6 and the window seat 8, and there is no gap between the rubber pad base 6 and the window seat 8 at the top of the glass 1. When the helicopter takes off and lands on the platform, there will be a downward force on the platform. When the downward load force of the window glass 1 exceeds the load, the gap between the rubber pad base 6 and the window seat 8 of the window on the platform accepts the downward movement of the glass 1 to a certain extent, thereby increasing the overall deformation load force of the window.

[0036] The side of the glass 1 pressing plate away from the sponge strip 4 is fixed to the window seat 8 by a cross recessed countersunk screw 5. By fixing the glass pressing plate 3 to the window seat 8, the glass pressing plate 3 can press the sponge strip 4 and the rubber pad base 6.

[0037] A lifting lug is also provided on the window seat 8 at the upper part of the window. Since the window is large and heavy, a crane is needed to lift the window. The lifting lug on the window seat 8 can facilitate the crane to lift the window as a whole. When the window is lifted to a suitable position, the lifting lug 8 can be cut off.

[0038] When the helicopter takes off and lands, there is a large downward load force on the helicopter platform, which will produce a large force on the cab. The sponge strip 4 is provided on the side of the cab window, which can relieve a large part of the load force and transfer the force to the sponge strip 4. Due to the properties of the sponge strip 4, this part of the force will be resolved by the sponge strip 4. The viscosity of the Sika glue 2 can increase the deformation ability of the glass 1. When the glass 1 moves up and down, the Sika glue 2 is still bonded to the position between the glass 1, the sponge strip 4 and the glass pressure plate 3. Since there is a certain gap between the rubber pad base 6 and the window seat 8, the rubber pad base 6 can accept a large force when the overall load exceeds the load, thereby minimizing the probability of window damage.

[0039] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention, and the purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the implementation methods of the present invention may be deformed or modified in any way without departing from the principles.
