Description

Technical Field

[0001] This invention belongs to the field of law enforcement vessel technology, and in particular relates to a high-speed law enforcement vessel with a steel-glass hybrid structure. Background Technology

[0002] The steel-glass hybrid high-speed law enforcement boat is a type of law enforcement vessel. Its hull below the main deck is made of steel, while the main deck and superstructure are made of fiber-reinforced plastic (fiberglass). It combines the advantages of the sturdiness and durability of steel hulls with the aesthetics and lightness of fiberglass. It features low sailing resistance and good wave-damping properties. The boat has a high speed and can be equipped with law enforcement equipment such as audible and visual alarms and cameras. It may also be equipped with rescue facilities such as rescue platforms. It is mainly used for patrol, law enforcement, and search and rescue missions by maritime, customs and other departments. For example, the patent with authorization announcement number CN215553987U discloses a steel-glass hybrid high-speed law enforcement boat.

[0003] In the management of rivers and lakes, law enforcement teams often rely on the high speed of high-speed law enforcement boats to deal with tasks such as emergency arrests and emergency response to the scene. However, the speed of the boat is closely related to its load and draft. When the load is too large, the draft will increase significantly. At the same time, the increase in water temperature will lead to a decrease in water density, which will also increase the draft. Excessive draft will increase the driving resistance and directly affect the high-speed driving performance.

[0004] In addition, thin ice may form on the surface of some rivers and lakes in winter. Although this type of ice will not completely block the navigation of the boat, it will force the high-speed law enforcement boat to be unable to maintain a high speed. This is because the impact force on the boat is large when traveling at high speed, and the thin ice will exert a reverse force on the boat, which can easily cause damage to the boat and thus threaten navigation safety.

[0005] Therefore, we propose a steel-glass hybrid high-speed law enforcement vessel to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to address the above-mentioned problems by providing a high-speed law enforcement vessel with a steel-glass hybrid structure.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a steel-glass hybrid high-speed law enforcement boat, comprising a high-speed law enforcement boat body, wherein a hollow leveling block is fixedly connected to the upper surface of the bow deck of the high-speed law enforcement boat body, and an air pump and a protective cover are fixedly connected to the upper surface of the hollow leveling block by connecting bolts, wherein the air outlet of the air pump is fixedly connected to the upper surface of the hollow leveling block.

[0008] The outer wall of the protective cover is provided with threaded holes, and the hole wall of the threaded holes is sealed with an air intake filter mechanism.

[0009] An adjustment mechanism is fixedly connected to the top of the protective cover, and an ice-breaking mechanism for the high-speed law enforcement vessel to break ice during its movement is fixedly connected to the moving end of the adjustment mechanism.

[0010] The high-speed law enforcement vessel has two arc-shaped reinforcing tubes fixedly connected to both sides of its hull, and the bottom ends of the two arc-shaped reinforcing tubes on the same side are fixedly connected to a draft control mechanism.

[0011] An alarm is fixedly connected to the top of the adjustment mechanism.

[0012] In the aforementioned steel-glass hybrid high-speed law enforcement vessel, the air intake filtration mechanism includes a threaded ring that is threadedly sealed to the protective cover. An air intake cover is fixedly connected to the outer end of the threaded ring, and a composite filter plate and a sponge filter block are installed on the inner wall of the air intake cover.

[0013] In the aforementioned steel-glass hybrid high-speed law enforcement vessel, the adjustment mechanism includes a support cylinder fixedly connected to the upper surface of the protective cover. A screw is connected to the top of the support cylinder via a rolling bearing. A self-locking motor is fixedly connected to the inner wall of the protective cover. A through hole is opened on the upper surface of the protective cover, and a sealed bearing cooperating with the drive shaft of the self-locking motor is fixedly connected to the wall of the through hole. The drive end of the self-locking motor is fixedly connected to the bottom end of the screw. An adjusting nut is threaded onto the wall of the screw. A rectangular through hole is opened on the outer wall of the support cylinder, and an extension rod is movably connected to the wall of the rectangular through hole. The side end of the extension rod is fixedly connected to the outer wall of the adjusting nut.

[0014] In the aforementioned steel-glass hybrid high-speed law enforcement vessel, the ice-crushing mechanism includes a connecting block fixedly connected to the outside of an extension rod. The upper surface of the connecting block has two threaded through holes, and the hole walls of the threaded through holes are threadedly connected to limit bolts. The bottom ends of the two limit bolts are threadedly connected to a U-shaped rod. The two top ends of the U-shaped rod are each provided with threaded blind holes that mate with the limit bolts. The bottom end of the U-shaped rod is fixedly sleeved with a connecting bearing. The outer ring of the connecting bearing is fixedly sleeved with a rotating plate. The two ends of the rotating plate are symmetrically connected with ice-crushing metal impact plates.

[0015] In the aforementioned steel-glass hybrid high-speed law enforcement vessel, the draft control mechanism includes a buoyancy cylinder fixedly connected to two arc-shaped reinforcing tubes. A connecting cover is fixedly embedded in the inner wall of the bottom end of the buoyancy cylinder. A water pressure level sensor is fixedly embedded in the side wall of the connecting cover. A through hole is opened in the side wall of the connecting cover, and a first normally closed solenoid valve is fixedly connected to the wall of the through hole. A delivery pipe is fixedly connected to the wall of one of the arc-shaped reinforcing tubes. The air inlet end of the delivery pipe passes through the fender of the high-speed law enforcement vessel body and is fixedly connected to a second normally closed solenoid valve. The air inlet end of the second normally closed solenoid valve is fixedly connected to the upper surface of the hollow leveling block.

[0016] In the aforementioned steel-glass hybrid high-speed law enforcement vessel, a PLC controller is fixedly connected to the inner wall of the protective cover, the alarm is electrically connected to the output terminal of the PLC controller via a wire, and the top outer wall of the support cylinder is fixedly connected to the bottom end of the alarm.

[0017] In the aforementioned steel-glass hybrid high-speed law enforcement vessel, both ends of the buoyancy cylinder are conical structures, and stabilizing fins are fixedly connected to the outer walls on both sides of the buoyancy cylinder at an incline. The bottom ends of the two buoyancy cylinders are on the same horizontal plane as the bottom end of the high-speed law enforcement vessel body.

[0018] In the aforementioned steel-glass hybrid high-speed law enforcement vessel, a partition plate is fixedly connected to the inner wall of the connecting cover, and the water pressure level sensor and the first normally closed solenoid valve are distributed on both sides of the partition plate.

[0019] Compared with existing technologies, the advantages of a steel-glass hybrid high-speed law enforcement boat are:

[0020] 1. Through the configured draft depth control mechanism, air pump, hollow leveling block, and air intake filter, when the steel-glass hybrid high-speed law enforcement boat is in use, the water pressure level sensor first detects the draft of the boat body. If the water pressure level sensor detects that the draft of the boat body exceeds the standard draft depth threshold preset by the PLC controller, the PLC controller controls the air pump and draft depth control mechanism to operate. The draft depth control mechanism can reduce the draft of the high-speed law enforcement boat body, so that the draft of the boat body reaches the standard draft depth, thus preventing the draft of the high-speed law enforcement boat body from being too large. By increasing drag and improving the speed of the high-speed law enforcement vessel, if the draft of the vessel is lower than the standard draft threshold preset by the PLC controller, the draft control mechanism reduces the buoyancy of the vessel, lowering its center of gravity and ensuring safe high-speed operation. This mechanism enables the high-speed law enforcement vessel to adjust its buoyancy, thereby adjusting its draft and minimizing drag. This not only improves the high-speed performance of the vessel but also enhances its reliability.

[0021] 2. By using a hydraulic level sensor and alarm, the high-speed law enforcement boat needs to be checked for overload before use to ensure its safe operation. If the draft measured by the hydraulic level sensor exceeds the over-warning draft threshold preset by the PLC controller, the PLC controller will activate the alarm to issue an audible and visual alarm, prompting staff to reduce the weight of the high-speed law enforcement boat in time. This prevents the overloaded boat from sinking during operation. This mechanism gives the high-speed law enforcement boat an overload warning function, ensuring its high-speed driving performance and improving its safety.

[0022] 3. Through the established adjustment and ice-breaking mechanisms, when a thin layer of ice interferes with the operation of the high-speed law enforcement vessel in winter, the water pressure level sensor converts the draft of the vessel into an electrical signal and sends it to the PLC controller. The PLC controller then controls the self-locking motor to start based on the received signal. The self-locking motor drives the screw to rotate, which in turn raises and lowers the adjusting nut. The adjusting nut, through the extension rod, connecting block, and limit bolt, raises and lowers the U-shaped rod a certain distance. This adjustment distance matches the draft of the high-speed law enforcement vessel, allowing the rotating plate and ice-breaking metal impact plate at the bottom of the U-shaped rod to contact the thin ice layer. After the U-shaped rod is adjusted, the PLC controller de-energizes the self-locking motor and locks it. During the subsequent operation of the high-speed law enforcement vessel, the rotating plate and ice-breaking metal impact plate rotate under the influence of water flow, breaking up the thin ice layer in front of the vessel and reducing damage. This mechanism enables the high-speed law enforcement vessel to break up thin ice in winter, improving its protective capabilities and thus enhancing its safety during winter operation.

[0032] An adjustment mechanism 6 is fixedly connected to the top of the protective cover 4. The adjustment mechanism 6 includes a support cylinder 61 fixedly connected to the upper surface of the protective cover 4. The top of the support cylinder 61 is connected to a screw 62 via a rolling bearing. A self-locking motor 63 is fixedly connected to the inner wall of the protective cover 4. A through hole is opened on the upper surface of the protective cover 4, and a sealed bearing 64 that cooperates with the drive shaft of the self-locking motor 63 is fixedly connected to the wall of the through hole. The drive end of the self-locking motor 63 is fixedly connected to the bottom end of the screw 62. An adjusting nut 65 is threaded onto the wall of the screw 62. A rectangular through hole 66 is opened on the outer wall of the support cylinder 61. An extension rod 67 is movably connected to the wall of the rectangular through hole 66. The side end of the extension rod 67 is fixedly connected to the outer wall of the adjusting nut 65.

[0033] The moving end of the adjustment mechanism 6 is fixedly connected to an ice-breaking mechanism 7 for the high-speed law enforcement vessel body 1 to drive and break ice. The ice-breaking mechanism 7 includes a connecting block 71 fixedly connected to the outside of the extension rod 67. The upper surface of the connecting block 71 has two threaded through holes, and the hole walls of the threaded through holes are threadedly connected to limit bolts 72. The bottom ends of the two limit bolts 72 are threadedly connected to a U-shaped rod 73. The two top ends of the U-shaped rod 73 are each provided with threaded blind holes 74 that cooperate with the limit bolts 72. The bottom end of the U-shaped rod 73 is fixedly sleeved with a connecting bearing 75. The outer ring of the connecting bearing 75 is fixedly sleeved with a rotating plate 76. The two ends of the rotating plate 76 are symmetrically connected with ice-breaking metal impact plates 77.

[0034] Two arc-shaped reinforcing pipes 8 are fixedly connected to both sides of the hull of the high-speed law enforcement vessel 1. The bottom ends of the two arc-shaped reinforcing pipes 8 on the same side are fixedly connected to a draft control mechanism 9. The draft control mechanism 9 includes a buoyancy cylinder 91 fixedly connected to the two arc-shaped reinforcing pipes 8. A connecting cover 92 is fixedly embedded in the inner wall of the bottom end of the buoyancy cylinder 91. A water pressure level sensor 93 is fixedly embedded in the side wall of the connecting cover 92. A through hole is opened in the side wall of the connecting cover 92, and a first normally closed solenoid valve 94 is fixedly connected to the wall of the through hole.

The air inlet end of the second normally closed solenoid valve 96 is fixedly connected to the upper surface of the hollow leveling block 2.

[0035] An alarm 10 is fixedly connected to the top of the regulating mechanism 6, and a PLC controller 11 is fixedly connected to the inner wall of the protective cover 4. The alarm 10 is electrically connected to the output terminal of the PLC controller 11 through a wire. The top outer wall of the support cylinder 61 is fixedly connected to the bottom end of the alarm 10. Both ends of the buoyancy cylinder 91 are conical structures. The outer walls on both sides of the buoyancy cylinder 91 are fixedly connected with stabilizing fins 12. The bottom ends of the two buoyancy cylinders 91 are on the same horizontal plane as the bottom end of the high-speed law enforcement boat body 1. A partition plate 13 is fixedly connected to the inner wall of the connecting cover 92. The water pressure level sensor 93 and the first normally closed solenoid valve 94 are distributed on both sides of the partition plate 13. The partition plate 13 can prevent the water flow discharged from the first normally closed solenoid valve 94 from interfering with the detection of the water pressure level sensor 93.

[0036] The air pump 3, the self-locking motor 63, the first normally closed solenoid valve 94 and the second normally closed solenoid valve 96 are all electrically connected to the output terminal of the PLC controller 11 via wires. The water pressure level sensor 93 is electrically connected to the input terminal of the PLC controller 11 via wires. The above-mentioned electrical components and electrical connections are all existing technologies and will not be described in detail here.

[0037] The operating principle of this invention is described as follows: When the steel-glass hybrid high-speed law enforcement boat is in use, the water pressure level sensor 93 first detects the draft of the high-speed law enforcement boat body 1. This is because the water pressure level sensor 93 is located at the bottom of the buoyancy cylinder 91, and the bottom of the buoyancy cylinder 91 is flush with the bottom of the high-speed law enforcement boat body 1. Therefore, the water pressure level sensor 93 detects the water level depth as the draft of the high-speed law enforcement boat body 1. Simultaneously, the water pressure level sensor 93 converts the detected draft depth into an electrical signal and sends it to the PLC controller 11. If the water pressure level sensor 93 detects that the draft of the high-speed law enforcement boat body 1 exceeds the preset standard draft depth threshold of the PLC controller 11, the PLC controller 11 controls the air pump 3 to operate based on the electrical signal fed back by the water pressure level sensor 93. The air pump 3 draws in outside air through the air intake filter mechanism 5. The air intake filter mechanism 5 can filter and remove water from the drawn air, and also... The filter plate 53 and sponge filter block 54 can be replaced periodically. The replacement cycle can be set according to the actual usage (e.g., once every 2 days) to ensure that the air intake filter mechanism 5 works continuously and effectively, so as to keep the air entering the hollow leveling block 2 as clean as possible. At the same time, the PLC controller 11 also controls multiple first normally closed solenoid valves 94 and second normally closed solenoid valves 96 to open. Then, the air inside the hollow leveling block 2 enters the buoyancy cylinder 91 through the second normally closed solenoid valve 96, the delivery pipe 95 and the arc-shaped reinforcing pipe 8. Moreover, the injected air can discharge the water temporarily stored at the bottom of the buoyancy cylinder 91 through the opened first normally closed solenoid valve 94, thereby increasing the buoyancy of the buoyancy cylinder 91, thereby increasing the buoyancy of the high-speed law enforcement boat body 1, reducing the draft of the high-speed law enforcement boat body 1, so that the draft of the high-speed law enforcement boat body 1 reaches the standard draft, avoiding the high-speed law enforcement boat body 1 from having an excessively large draft, increasing the driving resistance, and improving the high-speed law enforcement boat body 1's high-speed driving speed.

[0038] When the draft of the high-speed law enforcement vessel 1 reaches the preset standard draft threshold of the PLC controller 11, the water pressure level sensor 93 sends an electrical signal to the PLC controller 11. The PLC controller 11 then controls the air pump 3, the first normally closed solenoid valve 94, and the second normally closed solenoid valve 96 to de-energize based on the received signal. After de-energization, the first normally closed solenoid valve 94 and the second normally closed solenoid valve 96 close, ensuring the buoyancy adjusted by the buoyancy cylinder 91 remains stable. This allows the high-speed law enforcement vessel 1 to continue operating at the standard draft depth, minimizing its drag. If the draft of the high-speed law enforcement vessel 1 falls below the preset standard draft threshold of the PLC controller 11, the high-speed law enforcement vessel... The excessively high center of gravity of the law enforcement vessel 1 can lead to instability, making it prone to capsizing during high-speed operation. In this case, the PLC controller 11 energizes and opens the first normally closed solenoid valve 94 and the second normally closed solenoid valve 96, allowing an appropriate amount of water to enter the buoyancy cylinder 91, reducing buoyancy and increasing the draft of the high-speed law enforcement vessel 1. This improves the safety of the high-speed law enforcement vessel during high-speed operation. This mechanism enables the high-speed law enforcement vessel to adjust its buoyancy, thereby adjusting its draft and minimizing its driving resistance. This not only improves the high-speed driving performance of the high-speed law enforcement vessel but also enhances its reliability.

[0039] Before using the high-speed law enforcement boat, it is necessary to check whether the load exceeds the limit to ensure that the high-speed law enforcement boat body 1 can travel safely. If the draft measured by the water pressure level sensor 93 exceeds the over-warning draft threshold preset by the PLC controller 11, the PLC controller 11 will control the alarm 10 to issue an audible and visual alarm, prompting the staff to reduce the weight of the high-speed law enforcement boat body 1 in time to avoid the situation of water ingress and sinking during the operation of the overloaded high-speed law enforcement boat body 1. This mechanism enables the high-speed law enforcement boat to have an overload warning function, ensuring the high-speed driving performance of the high-speed law enforcement boat and improving the safety of the high-speed law enforcement boat in use.

[0040] When a thin layer of ice (0.5-3 cm thick) interferes with the operation of high-speed law enforcement vessels in winter, the water pressure level sensor 93 converts the draft of the vessel body 1 into an electrical signal and sends it to the PLC controller 11. The PLC controller 11 then controls the self-locking motor 63 to start based on the received signal. The self-locking motor 63 drives the screw 62 to rotate, which in turn causes the adjusting nut 65 to rise or fall. The adjusting nut 65, through the extension rod 67, connecting block 71, and limit bolt 72, causes the U-shaped rod 73 to rise or fall a certain distance. This adjustment distance matches the draft of the high-speed law enforcement vessel body 1, allowing the U-shaped rod 73 to move up or down a certain distance. The rotating plate 76 and the ice-breaking metal impact plate 77 at the bottom can contact the thin ice layer. After the U-shaped rod 73 is adjusted in height, the PLC controller 11 controls the self-locking motor 63 to cut off power and lock itself, ensuring that the position of the U-shaped rod 73 is stable. Then, during the operation of the high-speed law enforcement boat body 1, the rotating plate 76 and the ice-breaking metal impact plate 77 rotate under the action of water flow. During the rotation, they can break the thin ice layer in front of the high-speed law enforcement boat body 1, reducing the damage of the thin ice layer to the high-speed law enforcement boat body 1. This mechanism enables the high-speed law enforcement boat to break the thin ice layer in winter, improves the protection capability of the high-speed law enforcement boat in winter, and thus improves the safety of the high-speed law enforcement boat in winter.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
