Description

Technical Field

[0001] The invention belongs to the technical field of ship protection, and in particular relates to a cluster-type pirate protection device. Background Art

[0002] In recent years, global piracy has become increasingly rampant, and pirate hijacking incidents have occurred frequently, seriously endangering the safety of passenger and cargo ships, and has become a major public hazard in global shipping. At present, there is no effective defense against pirates. The traditional method is for countries to send warships to escort the sea areas where pirates are rampant. However, with 400 million square kilometers of sea areas in the world, tens of thousands of commercial and fishing ships cannot be defended by only dozens of warships. Obviously, it is only a temporary solution and not a permanent solution. At this stage, ships urgently need to have their own devices to defend against pirates, and this device must adapt to the characteristics of strong winds and waves at sea, and will not be damaged under the impact of huge winds and waves; at the same time, pirate ships are small targets and often disguised as civilian ships such as fishing boats to approach merchant ships. Therefore, the reaction time left for crew members after discovering pirates is often short, so this device needs to be simple to operate and can quickly deploy the device to form protection. At the same time, because commercial ships have to consider economic costs, this device also needs to be easy to install, low-priced, and usually does not take up space. Obviously, the development of devices that meet the above needs at the same time is imperative.

[0003] In view of this, the invention patent with the patent number CN200910309481.3 and the patent name "Horizontal guardrail and its anti-theft method and its application" includes a guardrail body and a mounting seat, the mounting seat is fixed on the outer wall of the protected object, the guardrail body and the mounting seat are connected by a load-limiting connection mechanism, when the destructive force between the two is greater than the limit value, the two are separated, and in the installed state, the guardrail body extends horizontally outward from the outer wall of the protected object. The horizontal guardrail is applied to the protection of buildings, or the horizontal guardrail is applied to the protection of ships to prevent pirates from climbing. The above structure has the advantage of simple structure, but it needs to be pre-installed, which is inconvenient to use. It can only achieve horizontal protection during protection, and the defense performance is poor. At the same time, the horizontally extended plate-type installation structure ignores the specifications for the hull structure bulwark in the ship shipping standard specification CB31851-83, changes the structure of the bulwark too much, and is likely to have a certain adverse effect on the structural strength of the ship. In addition, the invention patent with the patent number CN201210174520.5 and the name of the patent "An Improved Anti-Piracy Power Grid and Method" also discloses a design idea, which includes an arc-shaped protective device, a high-voltage pulse power grid and an early warning device; the arc-shaped protective device is fixedly installed on the edge of the hull, and the surface of the arc-shaped protective device is provided with a high-voltage pulse power grid, and an early warning device is also installed around the hull. When the pirates approach the hull, the early warning device can quickly alarm and automatically deploy the arc-shaped protective device without manual operation by the crew, and display the specific location of the pirates boarding the ship on the bridge or the engine room. When the pirates use the flying claws to forcibly board the ship, due to the special arc structure of the above-mentioned arc-shaped protective device, the flying claws cannot hook the hull, thereby preventing the pirates from boarding the ship; however, this type of structure ignores the harshness of the navigation environment, and it is obviously unable to withstand the huge force of the waves in actual use; at the same time, the highly automated device will inevitably bring about structural complexity and high sensitivity to the environment, which is more obvious in the exposed side area of ​​the ship that is exposed to wind and rain in daily life, and the service life and reliability are questionable. In addition, due to the limitation of its own structure, the above structure can only be installed in specific areas, such as the side of the ship, etc. However, there are actually many protrusions on the ship for the flying claws to climb, which makes the above arc-shaped protective device still have the problem of small protection area, which needs to be solved urgently. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and to provide a cluster-type pirate protection device with a reasonable structure and practical application, which has the advantages of a firm structure, easy installation, low use cost and strong protection performance. It is not easy to climb, can effectively reduce the risk of being attacked by pirates, and ultimately effectively improve the safety of ship navigation.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A cluster-type pirate protection device, characterized in that it includes a shaft and / or a head end arranged with protective pointed spines, the tail ends of two or more spines are fixed to each other to form a planarly arranged spine surface with the head ends facing outwards, and the tail ends of two or more groups of spine surfaces cooperate with each other to form a spine cluster.

[0007] Preferably, the tail ends of two adjacent groups of thorn surfaces are hinged to each other through a hinge axis, so that the thorn cluster forms a retractable structure that can be expanded and stored along the hinge axis; the two adjacent groups of thorn surfaces are connected to each other through a longitudinal connecting member, and the longitudinal connecting member is a longitudinal connecting rope or a longitudinal connecting chain or a telescopic rod or a hinged connecting rod.

[0008] Preferably, the outer shape of each group of spines is a fan-shaped fence that radiates outward from the hinge axis at the tail end, and adjacent spines at the same group of spines are connected to each other by a transverse connecting member, which is a transverse connecting rope or a transverse connecting chain or a fixed connecting rod.

[0009] Preferably, the hinge axis is arranged horizontally; a fixing seat that can be fixed on the ship's side railing is arranged at the lowest thorn surface and / or the hinge axis, and the tail end of the spines at the uppermost thorn surface extends outward to form an operating end; when the spines are in an expanded state, the operating end forms a snap fit with a preset snap-in socket at the lowest thorn surface or the ship's side railing.

[0010] Preferably, the hinge axis is arranged horizontally; a fixing seat that can be fixed on the ship's side railing is arranged at the lowest thorn surface and / or the hinge axis, and the tail end of the spines at the uppermost thorn surface extends outward to form an operating end; the operating end is driven by a power source to produce an articulated action relative to the hinge axis.

[0011] Preferably, the hinge axis is arranged horizontally; a fixing seat that can be fixed on the ship's side railing is arranged at the bottom layer of the thorn surface and / or the hinge axis, and a handle or a buckle is installed on the outer side of the top layer of the thorn surface; when the thorn cluster is in the unfolded state, the handle or the buckle forms a snap fit with the preset bayonet at the ship's side railing.

[0012] Preferably, the hinge axis is arranged horizontally; a fixing seat that can be fixed on the ship's side railing is arranged at the lowest thorn surface and / or the hinge axis, a rope is installed on the outer side of the spines at the uppermost thorn surface, and the extended end of the rope extends to the inner side of the ship's side railing; when the thorn cluster is in an unfolded state, a connection relationship is formed between the extended end of the rope and a preset connection point at the ship's side railing.

[0013] Preferably, the length of the thorns is 76-80 cm, the distance between the head ends of two adjacent thorns on the same group of thorn surfaces is 20 cm; the angle between two adjacent thorns on the same group of thorn surfaces is equal to the angle between adjacent thorn surfaces.

[0014] Preferably, the thorn is an axially telescopic rod, and can be driven by a power component to produce an axial telescopic action.

[0015] Preferably, a discharge structure is provided at the head end of the thorn, and the discharge structure and the power component are electrically connected to each other.

[0016] The beneficial effects of the present invention are:

[0017] 1) Cluster, that is, a bamboo-like cluster structure. The present invention forms a thorn surface with thorns, and then forms a thorn cluster with the thorn surface, thereby realizing a clump-like protective structure with the head end facing outward. By installing the present invention at any position of the ship's side railing or hull, a passive defense effect can be achieved for the position. When the present invention is actually used, once installed, a dense spear array-like protection can be formed, making it impossible for pirates to approach and board the ship; the device is not only very effective in preventing pirates on large commercial ships, but also on small commercial ships such as fishing boats and small yachts. It can also form an excellent protective effect. Moreover, because the cross-section of the device is extremely small, and the whole is assembled from independent thorns, there is no wind resistance surface, and it can withstand strong winds and waves without damage and deformation, and it does not excessively change the ship's side structure. It can adapt well to the actual environment of strong winds and waves at sea, and it is sturdy and practical.

[0018] In summary, the present invention has the advantages of firm structure, easy installation, low cost and strong protective performance. It is not easy to climb, can effectively reduce the risk of being attacked by pirates, and ultimately effectively improve the safety of ship navigation.

[0019] 2) On the basis of the above structure, the present invention is also retractable. In other words, after the barbed surface is formed, a hinged structure can be formed between adjacent barbed surfaces, and connected to each other through longitudinal connectors; when the uppermost barbed surface is pulled, the hinged action of the uppermost barbed surface will be transmitted to the adjacent lower barbed surface through the longitudinal connector, and so on, ultimately achieving the function of "a single move affects the entire body". In this way, the present invention can be conveniently folded to the outside of the ship's side when not in use, does not occupy space, and does not affect the daily work of the ship. After discovering pirates, due to the convenient operability, the present invention can be quickly opened in a very short time through the above-mentioned hinged and connected structure to form a cluster protection, which is extremely convenient and flexible to use.

[0020] 3) For the thorn surface, it can be a rake-like structure formed by multiple thorns arranged in parallel, or adjacent thorns can cross each other to form an inner or outer eight-shaped structure. The present invention preferably adopts a fan-shaped fence-like structure, so that the entire device presents a curved surface protection effect, thereby further improving its protection performance. At the same time, the transverse connector is different from the longitudinal connector. As a retractable part, the longitudinal connector itself can be a flexible structure, or it can be a folding and retractable structure similar to the hinged connecting rod at the rib of an umbrella; the transverse connector can be both a retractable part and a fixed connecting rod can be directly used to rigidly fix adjacent thorns at the same thorn surface to improve the convenience of retraction of the present invention. In addition, the rigidly fixed thorn surface will naturally swing down and fit on the ship's side railing when stored, that is, the volume can be minimized when stored, and will not affect the normal navigation of the ship.

[0021] 4) In actual operation, the present invention is preferably fixed on the ship's side railing; at the same time, when the thorn cluster is unfolded, it can be realized by manual operation or by an automated structure, such as a power motor drive or a hydraulic cylinder action, etc. Correspondingly, if a handle, buckle or rope is used to form a detachable online connection structure, the predetermined installation function of the present invention can also be achieved, and it will not be exhaustively described here.

[0022] 5) The angle between two adjacent spines on the same set of spines is equal to the angle between adjacent spines, that is, when the entire device is unfolded, it presents a uniformly distributed cluster structure; the distance between the head ends of two adjacent spines on the same set of spines is 20 cm, so as to minimize the risk of pirates crossing obstacles and improve its safety in use.

[0023] 6) Considering the practicality, the thorns can be designed as a telescopic structure driven by a power assembly to produce a telescopic action, so that when started, the thorns can produce telescopic actions independently or synchronously with each other to further improve the protection performance. The power assembly can be an electric slide rail or a crank rocker assembly. Similarly, a discharge structure such as a conductive sheet or a conductive column can be set at the thorn itself or the head end. The discharge structure is connected to the ship's own power or an independent power supply, which is also conducive to improving the overall protection effect of the device.

[0028] a-Ship railing

[0029] 10-thorn 11-operating end 20-hinged shaft

[0030] 30-longitudinal connector 40-transverse connector 50-fixing seat 60-bayonet DETAILED DESCRIPTION

[0031] For ease of understanding, the specific structure and working mode of the present invention are further described below in conjunction with the accompanying drawings:

[0032] The specific structure of the present invention refers to Figure 1-3 As shown, it includes a thorn 10 constituting the smallest unit. The thorn 10 can be selected according to the site conditions, such as a rod-shaped structure with a pointed head at the head end, or a rod body structure with saw teeth or a single thorn-shaped pointed head, or even directly using a conical rod body to form the thorn 10, etc., as long as it has an external protective effect.

[0033] In the present invention, the tail ends of the thorns 10 can be fixed to each other to form a fence structure arranged in a fan shape; to ensure the working stability of the fence structure, adjacent thorns 10 are fixed to each other through a transverse connecting member 40. The transverse connecting member 40 can be a transverse connecting rope or a transverse connecting chain or a fixed connecting rod, and can even be directly welded through a transverse mounting plate, so as to form a fence structure as shown in FIG. Figure 1 The overall layout of the thorn surface shown.

[0034] When multiple groups of thorn surfaces are formed, Figure 2-3 As shown, two adjacent groups of thorny surfaces are connected to form a hinge structure through a hinge shaft 20 arranged horizontally at the axis of the tail end. An operating end 11 extends outward from the tail end of the uppermost thorny surface; Figure 2 In the structure shown, a snap-fit ​​fit is formed between the operating end 11 and the bayonet 60 on the ship's side railing a. Of course, the bayonet 60 can also be arranged at the bottom layer of spines or even on a mounting piece fixed at other positions, as long as the timely positioning function of the operating end 11 can be realized. During actual operation, the operating end 11 can also be directly driven by a power source to form an automatic remote control start and stop or intelligent start and stop structure. The power source can be a linear travel component such as a gear rack structure, a crank slider structure, or a four-bar structure driven by a power motor, or it can be directly implemented using a piston cylinder, etc., which will not be repeated here. Adjacent spine surfaces can also be connected to each other by a longitudinal connector 30 as shown in Figure 2. Since the present device is preferably a retractable structure, the longitudinal connector 30 needs to be retractable, that is, it does not hinder the retraction and extension of adjacent spine surfaces; Figure 2The structure shown uses a flexible longitudinal connecting rope or longitudinal connecting chain, and in actual operation, a telescopic rod or an articulated connecting rod may be used as appropriate. For the telescopic rod, a conventional sleeve-type telescopic rod or a slide-type telescopic rod may be used; for the articulated connecting rod, if two rod bodies are articulated to each other, and the outer ends of the two rod bodies are respectively articulated to one group of adjacent thorn surfaces, when the adjacent thorn surfaces are separated from each other, the articulated connecting rod can be naturally driven to unfold.

[0035] Thus, through the above-mentioned retractable structure, the present invention can be directly welded or bolted to the ship's side railing a through the fixing seat 50 when in use; and at this time, the rigidly fixed independent thorn surface will be like Figure 3 The natural hem as shown is attached to the ship's side railing a, that is, the volume can be minimized when stored, and will not affect the normal navigation of the ship. When encountering pirates, the operating end 11 is directly or manually or automatically controlled to move downward, thereby driving the thorns to produce follow-up movements, and finally forming the following Figure 1-2 When necessary, even multiple groups of operating ends 11 of the present invention arranged in sequence along the length direction of the ship's side railing a can be synchronously driven by the same power source or corresponding linkage mechanism to achieve batch synchronous action, thereby further improving the operating efficiency of the present invention and achieving remarkable results.

[0036] Based on the above structure, the present invention has the following advantages:

[0037] 1. It has extremely strong protective performance and can effectively counter all known pirate climbing methods, including soft ladders and hard ladders with flying claws and hooks.

[0038] 2. The process of opening the protective device is fast. It can be opened quickly to form protection in a very short time after the pirates are discovered, and there is no need to deploy the equipment for a long time in advance.

[0039] 3. The structure is firm, and the cross-section is extremely small, with no wind-blocking surface. It can withstand the beating of strong winds and waves at sea without deformation and can adapt to the harsh marine environment.

[0040] 4. When not in use, it can be easily folded outside the ship's side, does not take up space, does not affect the daily work of the ship, and is conducive to popularization and use.

[0041] 5. Easy to install, cheap, and suitable for all types of large, medium and small ships, with broad commercial market prospects.
