Description

TECHNICAL FIELD

[0002] In order to realize the concept of low carbon, environmental protection and green, LNG, ammonia, methanol and other alternative fuels are widely used in ships in the shipbuilding industry. As a storage cabin for alternative fuels, the C-shaped storage tank is widely used in oil tankers, bulk carriers, ore carriers and other ships due to its simple structure, low cost and easy installation. The C-shaped storage tank used in ships is generally made of low-temperature steel or stainless steel, and the liquefied LNG or liquid ammonia stored therein is used as fuel for the main engine and generator. According to the requirements of the "Natural Gas Fuel Power Ship Specification", the fuel cabin should be protected to prevent mechanical damage. In order to ensure the safety of the C-shaped storage tank, in addition to providing reliable protection for the C-shaped storage tank, the C-shaped storage tank cannot be located within the operating range of the crane to prevent heavy objects from falling or colliding with the C-shaped storage tank during crane operation, which may cause mechanical damage to the C-shaped storage tank. The existing technology generally achieves protection by providing a structural platform above the C-shaped storage tank. This structural platform can prevent direct contact between the C-shaped storage tank and heavy objects falling from above. Since the structural platform is located above the C-shaped storage tank, it can prevent direct contact between the C-shaped storage tank and heavy objects falling from above. However, since the structural platform is made of steel plates and bones, it is heavy and expensive to manufacture, and it can only protect against falling objects from above, but it lacks protection against side collisions.

[0037] In large ships, C-type storage tanks (which can store dual fuel) are generally located in the deck crane coverage area. When operating the crane, the weight lifted or the boom will directly collide with the C-type storage tank, which may cause mechanical damage to the C-type storage tank, and eventually may cause the liquid in the tank to leak due to structural damage, causing irreparable loss.

[0038] The main body of this application adopts a truss-type steel structure, equipped with bulb flat steel or flat steel fences. The truss-type steel structure at the top of the C-type storage tank, where workers operate, is covered with corrugated steel plates or steel gratings, which are lightweight and have low manufacturing costs. The protective cover composed of the truss-type steel structure and fences includes the top and sides of the C-type storage tank, completely eliminating the risk of mechanical damage to the C-type storage tank from crane operations, falling heavy objects, etc. Compared with the structural platform, the protective cover composed of the truss-type steel structure and fences has better flexibility and better energy absorption effect for impact protection.

The C-type storage tank 5 located on the right side of the flat layer does not have a schematic diagram of its protective device. Therefore, it needs to be explained in this text that since the two C-type storage tanks 5 are symmetrically arranged about the middle flat layer, the protective devices for the C-type storage tank 5 also need to be symmetrically arranged.

[0041] exist Figure 1 In the diagram, the protective device for the C-type storage tank 5 located on the left side of the level floor only shows the protective structures of the middle and front ends of the C-type storage tank 5. The protective structure of the spherical structure at the rear end of the C-type storage tank 5 is not shown. It should be noted that the protective structure of the spherical structure at the rear end of the C-type storage tank 5 is the same as that at the front end. Therefore, the protective device surrounding the C-type storage tank 5 is symmetrical. Relevant technical personnel can complete the diagram based on the protective structure at the front end of the C-type storage tank 5. Figure 1 The protective structure installed at the rear end of the C-type storage tank 5 forms a complete protective device.

[0042] The application provides a protection device for a C-shaped storage tank, which mainly comprises a support platform 1, a support column 2 and a top protection platform 3. The support platform 1 comprises two longitudinal base plates 101, which are arranged on the two sides of the C-shaped storage tank 5 respectively, and the lower end of each longitudinal base plate 101 is provided with a support plate 102, and an elbow plate 103 is arranged on the side of the longitudinal base plate 101 facing the C-shaped storage tank 5; the support column 2 comprises a plurality of support columns 2, and the bottom ends of the plurality of support columns 2 are arranged on the elbow plates 103 in parallel; the top protection platform 3 comprises a truss structure arranged above the C-shaped storage tank 5, and a covering assembly is arranged on the truss structure, and the two sides of the truss structure are connected with the upper ends of the support columns 2 respectively.

[0043] Specifically, two saddles are arranged on the lower end of the C-shaped storage tank 5 along the length direction respectively, the support platform 1 supports and connects the two saddles through the longitudinal base plates 101, the support plates 102 at the lower end of the longitudinal base plates 101 and the elbow plates 103 on the side of the longitudinal base plates 101 facing the C-shaped storage tank 5, the support platform 1 indirectly supports the C-shaped storage tank 5, and a stable foundation support is provided; a plurality of support columns 2 are arranged on the elbow plates 103 on the two sides of the C-shaped storage tank 5 and along the length of the C-shaped storage tank 5 in parallel, so that the load of the support columns 2, the truss structure and the covering assembly on the support platform 1 is effectively dispersed, the carrying capacity of the support platform 1 is improved, and the C-shaped storage tank 5 is protected from side collision; the top protection platform 3 adopts a truss structure and is connected with the upper ends of the support columns 2, so that a firm and light protection cover is formed, the overall weight of the protection device is reduced, the cost is also reduced, external impact energy can be effectively absorbed and dispersed, and the C-shaped storage tank 5 is protected from falling objects above and side collision; the covering assembly is arranged on the truss structure and has the functions of protection and passing.

[0044] Optionally, the covering assembly comprises but is not limited to a steel grating or a perforated steel plate.

[0045] Specifically, the steel grating or the perforated steel plate not only ensures the structural firmness but also reduces the overall weight, provides reliable protection function to prevent falling objects above from damaging the C-shaped storage tank 5, and provides a safe passing platform for the operator.

[0046] In the optional embodiment, the steel grating arranged on the truss structure on the top protection platform 3 can be replaced by resin. Under the condition of meeting the working load requirement, the replacement of the resin also helps to reduce the weight of the ship body and resist seawater corrosion.

[0047] In this specific embodiment, according to the shape of the saddle provided by the manufacturer to the C-shaped tank 5, the form of the plate plus elbow plate 103 is used, that is, the longitudinal base plate 101, the support plate 102 and the elbow plate 103 are used to connect the saddles at the front and rear ends of the C-shaped tank 5 to form the support platform 1 of the bottom end protective cover of the C-shaped tank 5; wherein the longitudinal base plate 101 can adopt an I-shaped steel structure, a section of I-shaped steel is arranged on both sides of the length direction of each C-shaped tank 5 along the length direction, the support plate 102 is arranged on the bottom end of the longitudinal base plate 101 on both sides, the support plate 102 provides a support structure for the longitudinal base plate 101, the elbow plate 103 is arranged on the side of the longitudinal base plate 101 facing the C-shaped tank 5, the top end position of the elbow plate 103 is slightly lower than the top end of the longitudinal base plate 101, and the elbow plate 103 provides a support structure for the support column 2; a plurality of support columns 2 are arranged side by side on the elbow plate 103, the lower end of the support column 2 is connected with the elbow plate 103, the upper end of the support column 2 is connected with the truss structure of the top protective platform 3, and the support column 2 protrudes outward relative to the C-shaped tank 5. This arrangement can effectively protect the side of the C-shaped tank 5, and can also prevent the steel grating or expanded steel plate laid on the truss structure from being hit by the falling object of the crane above the C-shaped tank 5 and then rolling downward.

[0048] In one embodiment, the truss structure plus covering assembly is more lightweight and flexible than the traditional steel plate plus bone material structure platform. This means that it can deform to a certain extent to absorb energy when subjected to external impact, rather than rigidly resisting the impact, thereby reducing the impact force transmitted to the C-shaped tank 5.

[0049] Optionally, the protection device of the C-shaped tank 5 further comprises a lateral protection assembly 4 arranged on the outer side of the upper end of the support column 2.

[0050] Specifically, the lateral protection assembly 4 is installed on the outer side of the support column 2 arranged on both sides of the C-shaped tank 5, which provides additional lateral protection for the C-shaped tank 5. The lateral protection assembly 4 can prevent damage caused by the lateral swing of the falling object of the crane to the tank body on both sides of the C-shaped tank 5, and plays a buffering and blocking role.

[0051] Optionally, the lateral protection assembly 4 includes but is not limited to a flat steel fence or a spherical flat steel fence.

[0052] Specifically, the flat steel fence or the spherical flat steel fence focuses on lateral protection, and the flat steel fence or the spherical flat steel fence deforms to a certain extent to absorb energy when subjected to external impact, thereby reducing the impact force transmitted to the C-shaped tank 5.

The lateral protection assembly 4 can be composed of flat steel fences or ball flat steel fences. The flat steel fences or ball flat steel fences can also be truss structures. When a collision occurs, the flat steel fences or ball flat steel fences can absorb the collision energy by deforming themselves, thereby playing a buffering role and protecting the C-shaped storage tank 5 from direct mechanical damage.

[0054] In an optional embodiment, the flat steel fences or ball flat steel fences can be replaced by angle steels, square tubes or round tubes, etc. The outer shape of the flat steel fences or ball flat steel fences can be set as a square fence or an arc fence.

[0055] Optionally, the support column 2 is arranged in a V shape, and the V-shaped opening faces the C-shaped storage tank 5.

[0056] Specifically, the upper end and the lower end of the support column 2 form a V-shaped structure. The V-shaped support column 2 can effectively resist the impact force from the side, provide stronger lateral support, and also enhance the flexible energy absorption characteristics of the support column 2, thereby ensuring the safety of the C-shaped storage tank 5 under the action of a crane or other external forces.

[0057] In this embodiment, the flat steel fences or ball flat steel fences in the lateral protection assembly 4 are arranged in a rectangular shape, the length of which is arranged along the length direction of the C-shaped storage tank 5, and the upper end of the flat steel fences or ball flat steel fences is connected to the truss structure, and the lower end of the flat steel fences or ball flat steel fences is connected to the middle of the support column 2. In this way, the flat steel fences or ball flat steel fences cover the V-shaped upper end of the support column 2 as shown in the figure. Figure 1

[0058] Optionally, the support column 2 is arranged in an arc shape, and the arc-shaped opening faces the C-shaped storage tank 5.

[0059] Specifically, the arc-shaped structure of the support column 2 can more evenly distribute the load and reduce local stress concentration.

[0060] In the above embodiments, the support column 2 can be arranged in a V shape or an arc shape. This directly ensures that the support column 2 protrudes outward towards the sides of the C-shaped storage tank 5, thereby effectively protecting the two sides of the C-shaped storage tank 5. Even when a crane drops an object and hits the C-shaped storage tank 5 from the side, the support column 2 can absorb the impact energy by deforming to some extent, thereby protecting the C-shaped storage tank 5.

[0061] In the above embodiments, the support column 2 and the top protection platform 3 form a protection cover, and the shape of the protection cover can also be replaced by an arc-shaped protection cover, i.e., the support column 2 is an arc-shaped support column 2, and the truss structure of the top protection platform 3 is an arc-shaped truss.

[0062] Optionally, an inclined support column 201 is arranged at the upper end of the support column 2, and one end of the inclined support column 201 is connected to the truss structure. ​

[0064] Optionally, the support column 2 and the diagonal brace column 201 adopt an I-beam structure.

[0065] Specifically, the support column 2 and the diagonal brace column 201 adopt an I-beam structure, which can provide high strength-to-weight ratio and excellent bending resistance, is easy to process and install, and reduces manufacturing cost.

[0066] In this embodiment, when the support column 2 is arranged in a V shape, the upper end of the support column 2 is connected with the diagonal brace column 201, the diagonal brace column 201 is connected with the truss structure, and the I-beam forms a triangular structure, which is light and firm.

[0067] Optionally, the number of the support columns 2 on the knee plates 103 on both sides of the C-shaped storage tank 5 is equal, and the number of the diagonal brace columns 201 is equal to the number of the support columns 2.

[0068] Specifically, the number of the support columns 2 on both sides of the C-shaped storage tank 5 is equal, which ensures that the support structures on both sides of the C-shaped storage tank 5 are symmetrical and evenly share the load; each support column 2 has a diagonal brace column 201 at the upper end to provide additional support and improve the overall structural strength.

[0069] Optionally, at the end of the knee plate 103, at least one lower end of the support column 2 is arranged to be inclined outward from the spherical structure at the end of the C-shaped storage tank 5, at least one lower end of the support column 2 is arranged to be crossed with other lower ends of the support columns 2, and at least one upper end of the support column 2 is arranged to be parallel to other upper ends of the support columns 2.

[0070] Specifically, since the two ends of the C-shaped storage tank 5 are spherical structures, at the two ends of the knee plate 103, the support columns 2 are arranged to have crossed lower ends and parallel upper ends, so as to extend the coverage area of the upper ends of the support columns 2 and the top protection platform 3 on the top and side of the C-shaped storage tank 5, and protect the spherical structures at the two ends of the C-shaped storage tank 5.

[0071] In this embodiment, as shown in Figure 1 the lower ends of the two support columns 2 at the end of the knee plate 103 are arranged to be crossed with the lower ends of the other two adjacent support columns 2, and the lower ends of the four support columns 2 form a W shape, and the upper ends thereof are still arranged to be parallel, so as to protect the end of the C-shaped storage tank 5.
