TECHNICAL FIELD
[0001] The present application relates to the field of hatch cover protection equipment, in particular to a reinforcing and pressure resisting device for a ship hatch cover. BACKGROUND
[0002] A hatch cover is a cover and its opening and closing device used to close various hatches on ships, aircraft and spacecraft and the like. Its main function is to prevent waves and rain from entering the cargo hold. Some hatch covers also bear the weight of cargo on the deck to prevent air flow or external objects from entering the cabin, while protecting the risk of internal transportation of oil and other leaks, maintaining the stability and safety of the transportation tool.
[0003] The structural strength and stability of the existing hatch cover will be affected by the environment. When facing external pressure or impact, the hatch cover without a reinforcing and pressure resisting device is more likely to deform, displace or even be damaged, which will directly threaten the normal use and function of the hatch cover. Since the hatch cover is easily damaged, frequent maintenance and replacement are required, which will increase the operating cost of the ship and reduce its economic benefit. SUMMARY
[0004] In order to improve the connection strength and pressure resistance of the hatch cover and the hatch body, the present application provides a reinforcing and pressure resisting device for a ship hatch cover.
[0005] The reinforcing and pressure resisting device for a ship hatch cover provided by the present application adopts the following technical scheme:
[0006] A reinforcing and pressure resisting device for a ship hatch cover, comprising a hatch body and a hatch cover, the hatch body is provided with a hatch, the hatch cover is buckled with the hatch, the hatch cover is provided with a reinforcing assembly and a pressure resisting assembly, the circumferential direction of the hatch cover is detachably connected with the hatch body through the reinforcing assembly, and the top of the hatch cover is connected with the hatch body through the pressure resisting assembly, so as to enhance the connection strength and pressure resistance of the hatch cover and the hatch body.
[0007] By adopting the above technical scheme, the reinforcing assembly enhances the circumferential structural strength of the hatch cover, so that it can withstand greater external pressure and impact. This helps to prevent the hatch cover from deforming or separating from the hatch body in harsh environments, ensuring its normal function and safety. The pressure resisting assembly resists the pressure on the hatch cover, whether it is from the external environment or the weight of the internal equipment. This helps to ensure that the hatch cover will not deform or be damaged when it is under pressure, maintains its good working condition, can effectively disperse the pressure on the hatch cover and evenly distribute it to the entire structure, thereby avoiding damage caused by excessive local pressure.
[0008] Optionally, the reinforcing assembly comprises a support and a limiting frame, the support is connected to the cabin body, the limiting frame is connected to the cabin cover, the part of the limiting frame extending out is provided with a clamping groove, the support is rotationally connected to a limiting rod, and the free end of the limiting rod is clamped with the limiting frame.
[0009] By adopting the above technical scheme, the clamping of the clamping groove and the limiting rod realizes the accurate positioning and fixing between the cabin cover and the cabin body. This clamping mechanism enables the cabin cover to be accurately installed on the cabin body and is not easy to loosen or fall off, improving the use performance and reliability of the equipment. The reinforcing assembly design is flexible and can adapt to cabin bodies and cabin covers of different sizes and shapes. By adjusting the length, angle and other parameters of the support and the limiting frame, the reinforcing needs of different equipment can be easily met.
[0010] Optionally, the limiting rod is threadedly connected with a locking member, and the locking member abuts against the upper end surface of the limiting frame.
[0011] By adopting the above technical scheme, the locking member is connected with the limiting rod through threads, which can provide an additional locking force to ensure that the limiting rod is firmly fixed in the clamping groove and prevent it from loosening due to vibration or external force. At the same time, an additional support point is formed, which enhances the connection stability between the cabin cover and the cabin body. This helps to reduce noise and wear caused by the movement or vibration of the cabin cover, and improves the stability of the overall structure.
[0012] Optionally, the anti-pressure assembly comprises a reinforcing frame and a plurality of reinforcing ribs, the reinforcing frame is fixedly connected to the top of the cabin cover, the plurality of reinforcing ribs are uniformly distributed and fixedly connected to the outer wall of the reinforcing frame, and the plurality of reinforcing ribs are fixedly connected with the cabin cover.
[0013] By adopting the above technical scheme, the reinforcing frame and the reinforcing ribs form a solid support structure, effectively dispersing the pressure borne by the cabin cover and evenly distributing it to the entire structure, thereby reducing the risk of local overload. At the same time, the reinforcing frame also enhances the rigidity and stability of the cabin cover, so that the cabin cover is not easy to deform or be damaged when subjected to external force.

[0015] By adopting the above technical scheme, the pressurizing rod further applies pressure to the cabin cover, which helps to improve the safety of the entire equipment. In a high-pressure environment, the pressurizing rod can effectively protect the cabin cover from damage and prevent safety accidents caused by cabin cover rupture or failure.
[0016] Optionally, the free end of the pressurizing rod is connected with a positioning rod, one end of the positioning rod is fixedly connected with a rotating disc, the other end is rotatably connected with the cabin body, and the rotating disc abuts against the pressurizing rod.
[0017] By adopting the above technical scheme, the pressurizing effect of the positioning rod on the top of the hatch cover can optimize the stress distribution. By reasonably arranging the number and position of the positioning rod, the pressure can be evenly distributed to different areas of the hatch cover, avoiding structural damage caused by excessive local stress. This optimized stress distribution helps to improve the pressure resistance and overall strength of the hatch cover.
[0018] Optionally, the side of the hatch cover facing the cabin body is provided with a bearing ring, one side of the bearing ring is fixedly connected with the hatch cover, a plurality of sealing grooves are formed in the outer wall of the bearing ring, and a sealing ring is arranged in each sealing groove and abuts against the cabin body.
[0019] By adopting the above technical scheme, the most basic and core function of the sealing ring is to ensure the effective sealing between the hatch cover and the cabin body. It has good sealing performance and can effectively prevent liquid, gas or other media from leaking between the hatch cover and the cabin body. The sealing ring can maintain stable performance in harsh working environment and effectively prevent medium leakage for a long time.
[0020] Optionally, the reinforcing assembly has four groups, and the four groups of reinforcing assemblies are evenly distributed in the circumferential direction of the hatch cover.
[0021] By adopting the above technical scheme, the evenly distributed multiple groups of reinforcing assemblies can effectively improve the overall structural strength of the hatch cover. The reinforcing assemblies increase the support points of the edges and top of the hatch cover, forming a stable support network. When the hatch cover is subjected to external pressure or impact force, it can better disperse and withstand these forces, thereby preventing deformation or damage of the hatch cover.
[0022] In summary, the present application has at least one of the following beneficial technical effects:
[0023] This helps to prevent the hatch cover from deforming or separating from the cabin body in harsh environments, ensuring its normal function and safety. The pressure resistance assembly bears the pressure on the hatch cover, ensuring that the hatch cover will not deform or be damaged when subjected to pressure, maintaining its good working condition. It can effectively disperse the pressure on the hatch cover and evenly distribute it to the entire structure, thereby avoiding damage caused by excessive local pressure;
[0024] The clamping of the clamping groove and the limiting rod realizes the accurate positioning and fixing between the hatch cover and the cabin body. This clamping mechanism enables the hatch cover to be accurately installed on the cabin body and not to be easily loosened or fallen off;
[0025] The use performance and reliability of the equipment are improved, and the reinforcement requirements of different equipment can be easily met by adjusting the length, angle and other parameters of the support and the limiting frame. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION
[0031] The application will be further described in detail below with reference to the accompanying drawings.
[0032] The application discloses a reinforcing and pressure resisting device of a ship hatch cover. EMBODIMENT
[0033] Reference Figure 1 and Figure 2 The reinforcing and pressure resisting device of the ship hatch cover 11 comprises a hatch body 1 and a hatch cover 2. The hatch body 1 is provided with a hatch 11 for connecting the inside of the hatch body 1 and the outside. The hatch cover 2 is sealed with the hatch 11. The hatch cover 2 is provided with a reinforcing assembly 3 and a pressure resisting assembly 4. The reinforcing assembly 3 cooperates with the pressure resisting assembly 4 to enhance the overall structural strength of the hatch cover 2, so that the hatch cover 2 can withstand greater external pressure and impact. This helps to prevent the hatch cover 2 from deforming or breaking in harsh environments, and ensures the normal function and safety of the hatch cover 2.

When the limiting rod 34 is clamped in the clamping groove 33, the locking piece 35 is rotated to abut against the limiting frame 32, thereby reinforcing the hatch cover 2. In this embodiment, there are four groups of reinforcing assemblies 3 which are uniformly distributed in the circumferential direction of the hatch cover 2. These reinforcing assemblies 3 can effectively disperse the load borne by the hatch cover 2 and the cabin body 1. This not only prevents local overload, but also ensures that the stress of the whole structure is uniform, thereby improving the overall load-bearing capacity.

The reinforcing frame 41 is provided with a limiting groove 43, the hatch body 1 is connected with a pressurizing rod 44, the limiting groove 43 is located on the rotating path of the pressurizing rod 44, the pressurizing rod 44 is clamped with the limiting groove 43 and exerts pressure on the reinforcing frame 41 to resist the pressure in the hatch body 1, further reducing the risk of deformation of the hatch cover 2, and the end of the pressurizing rod 44 away from the hatch body 1 is a free end. The pressurizing rod 44 is provided with a positioning hole 45, and the hatch body 1 is provided with a limiting hole 12, the positioning hole 45 is in communication with the limiting hole 34. In this embodiment, the positioning hole 45 is a through hole, and the limiting hole 12 is a threaded hole. The pressurizing rod 44 is connected with a positioning rod 46, the positioning rod 46 is a threaded rod, the positioning rod 46 is inserted into the positioning hole 45 and is screwed with the limiting hole 12, and the end of the positioning rod 46 away from the hatch body 1 is fixedly connected with a rotating disc 47, so that the operator can rotate the threaded rod to make the pressurizing rod 44 abut against the reinforcing frame 41, thereby ensuring the sealing performance and the anti-pressure performance of the hatch cover 2 and the hatch body 1.
[0037] The implementation principle of the embodiment 1 is as follows: the operator rotates the hatch cover 2 to make the hatch cover 2 buckled with the hatch opening 11 of the hatch body 1 and the sealing ring 23 abut against the inner wall of the hatch body 1, so that the hatch body 1 forms a closed space, then the limiting rod 34 is flipped, the limiting rod 34 is clamped in the clamping groove 33, the locking member 35 is rotated to make the locking member 35 abut against the limiting frame 32, thereby pressurizing the connection between the hatch cover 2 and the hatch body 1 and improving the anti-pressure strength of the edge of the hatch cover 2. Then the pressurizing rod 44 is rotated to make the pressurizing rod 44 clamped with the limiting groove 43, the positioning hole 45 and the limiting hole 12 are in communication, the operator holds the rotating disc 47 and inserts the positioning rod 46 into the positioning hole 45, rotates the rotating disc 47 to make the positioning rod 46 screwed with the limiting hole 12, increases the pressure of the pressurizing rod 44 on the reinforcing frame 41, that is, increases the pressure on the top of the hatch cover 2, so that the hatch cover 2 is not easily deformed or damaged when bearing external pressure or impact force, and the stability and safety of the hatch cover 2 under various extreme conditions are ensured.
