Abstract
Description
Technical Field
[0001] This utility model relates to the field of early warning devices, and more specifically, to an anti-collision early warning device. Background Technology
[0002] With the rapid development of import and export, maritime trade has become more frequent and faster, resulting in an increasing number of ships sailing at sea. However, maritime navigation faces extremely complex weather conditions. In severe weather, maritime facilities are prone to collisions, such as ships, navigation marks, and wind power facilities, leading to huge economic losses. Existing collision avoidance warning devices, while providing collision warnings, mostly reduce collision damage through anti-collision air cushions. For example, patent CN 217125090 U discloses "a ship collision avoidance warning device, including a warning device body, multiple fixed blocks symmetrically arranged on both sides of the warning device body, each fixed block having a rotating connecting piece hinged to its side, and the ends of each rotating connecting piece being movably connected to the opposite surfaces of two protective plates via telescopic rods; anti-collision air cushions are provided on the outer surfaces of the two protective plates; the warning device body is equipped with a display screen, control buttons, and a speaker; the bottom of the warning device body has a base plate with a first reserved hole and a second reserved hole symmetrically arranged on the base plate." This utility model, through the cooperation of protective plates and anti-collision air cushions, can prevent obstacles from directly contacting the hull when a ship is impacted and can deflect the impacting obstacle. The device buffers vibrations generated by objects and adjusts the protective height of the protective plate and air cushion using telescopic rods, allowing them to better protect the ship and prevent damage. The device uses telescopic rods to extend the protective plate outwards, and then adjusts the angle via rotating connectors. An air cushion is installed on the outer side of the protective plate. However, in the event of a collision, the impact force is relatively large, which may directly damage the telescopic rods and rotating connectors. The telescopic rods are primarily subjected to axial force, and are prone to bending and breakage under radial impact during a collision. The stress concentration at the hinge points of the rotating connectors can easily cause them to detach after exceeding the material's yield strength, leading to the protective plate and air cushion falling off. Furthermore, the air cushion's elasticity decreases at low temperatures (<0℃) and its airtightness decreases at high temperatures (>40℃), making the internal metal components more susceptible to accelerated corrosion in high-salt-spray environments, leading to weakened connection strength. Utility Model Content
[0003] The purpose of this invention is to provide a collision warning device that solves the problem that the protective plate of the existing collision warning device is easy to fall off when a collision occurs at sea.
[0004] The embodiments of this utility model are achieved through the following technical solutions:
[0005] A collision avoidance warning device includes a mounting part and a shock absorption mechanism. The mounting part is used to mount a detection device and is a box-shaped structure open at one end. The shock absorption mechanism includes a protective plate, a groove, a guide rod, a guide block, an elastic element, and a rotating rod. The protective plate is slidably connected to the open end of the mounting part, with the sliding direction along the depth direction of the mounting part. The groove is connected to the side of the protective plate near the mounting part. The guide rod is connected to the inner wall of the groove, with the length direction of the guide rod consistent with the length direction of the groove. The guide block is sleeved on the guide rod and slidably connected to it. The elastic element is provided between the guide block and the end wall of the groove. One end of the rotating rod is rotatably connected to the slider. As the other end of the rotating rod extends away from the bottom wall of the groove, it gradually moves away from the connection end between the elastic element and the groove.
[0006] Preferably, the shock absorption mechanism includes: a mounting plate, the groove is disposed on the mounting plate, and the mounting plate is connected to the protective plate.
[0007] Preferably, at least two grooves are provided on one of the mounting plates, and the central axes of the two grooves intersect; each groove is provided with an elastic element, a guide block and a rotating rod at both ends; the free ends of the two rotating rods on the same groove extend toward the middle of the groove.
[0008] Preferably, the shock absorption mechanism further includes a rolling element, which is rotatably connected to the free end of the rotating rod, and the distance between the highest point of the rolling element and the groove is greater than the distance between the highest point of the rotating rod and the groove.
[0009] Preferably, the shock absorption mechanism further includes a protective air cushion, which is connected to the outer wall of the protective plate, and a gap is left between the outer wall of the protective air cushion and the inner wall of the mounting part.
[0010] Preferably, the inner sidewall of the mounting part is provided with a slide rail, and the sidewall of the protective plate is provided with a slider that cooperates with the slide rail.

[0014] Preferably, the outer wall of the mounting part is provided with a laser rangefinder, a buzzer and a warning light; the buzzer and the warning light are both electrically connected to the laser rangefinder.
[0015] This utility model has at least the following beneficial effects:
[0016] This invention adds a collision-resistant structure to the protective plate, distinct from an air cushion, giving the protective plate a degree of mobility and enhancing the collision-resistant performance of the warning device. When the warning device is subjected to an impact force, the protective plate moves towards the mounting part, thereby driving the rotating rod to push the slider. The slider moves along the guide rod and compresses the elastic element, reducing or avoiding damage to the warning device from the impact force. After the impact force disappears, the protective plate can be reset under the action of the elastic element. This invention employs a multi-directional force dispersion design with the rotating rod and elastic element working together. By having the guide block slide along the guide rod, the radial force is converted into the axial compressive force of the elastic element, reducing the possibility of structural damage.

Detailed Implementation
[0025] To make the objectives, methods, and advantages of the embodiments of this utility model clearer, the methods in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.
[0026] Example 1: As Figure 1-4 As shown, a collision avoidance warning device includes a mounting part 1 and a shock absorption mechanism 8. The mounting part 1 is used to mount a detection device and is a box-shaped structure open at one end. The shock absorption mechanism 8 includes a protective plate 802, a groove 805, a guide rod 806, a guide block 807, an elastic element 808, and a rotating rod 8010. The protective plate 802 is slidably connected to the open end of the mounting part 1, and the sliding direction is along the depth direction of the mounting part 1. The groove 805 is connected to the side of the protective plate 802 near the mounting part 1. The guide rod 806 is connected to the groove 805. The inner wall of the 05 is connected, and the length direction of the guide rod 806 is consistent with the length direction of the groove 805; the guide block 807 is sleeved on the guide rod 806 and slidably connected with the guide rod 806; the elastic element 808 is provided between the guide block 807 and the end wall of the groove 805; one end of the rotating rod 8010 is rotatably connected to the slider 8041; as the other end of the rotating rod 8010 extends in a direction away from the bottom wall of the groove 805, it gradually moves away from the connection end between the elastic element 808 and the groove 805.
[0027] In specific implementation, the elastic element 808 can be a spring damper, which generally consists of a spring, compression damping, rebound damping, and inner and outer tube structures. Spring dampers are existing technology and will not be described in detail in this embodiment. The detection device can be a ranging device, which can be used to detect the distance between the offshore facility and surrounding facilities. One end of the elastic element 808 can be connected to the end wall of the tank 805. In this embodiment, the mounting part 1 can be installed on the outer wall of the offshore facility. This embodiment adds a collision-resistant structure to the protective plate 802, different from the air cushion, so that the protective plate 802 and the mounting part 1 not only have a certain degree of relative mobility, thereby reducing damage and detachment of the protective plate 802, but also further increase the collision-resistant performance of the early warning device. When the warning device is subjected to an impact force, the protective plate 802 moves toward the mounting part 1 under pressure, thereby driving the rotating rod 8010 to push the slider 8041. The slider 8041 moves along the guide rod 806 and compresses the elastic element 808, reducing or avoiding damage to the warning device caused by the impact force. After the impact force disappears, the protective plate 802 can be reset under the action of the elastic element 808.
[0028] As an example, the surface of the guide rod 806 can be plated with hard chrome (hardness ≥60HRC), and the guide block 807 can be made of polytetrafluoroethylene (PTFE) with embedded bronze powder. The self-lubricating properties of PTFE reduce the coefficient of friction (≤0.05), while the bronze powder enhances wear resistance and meets the requirements of long-term high-frequency sliding at sea.
[0029] As an example, since a single elastic element 808 is difficult to adapt to different collision intensities (such as minor impacts and severe impacts), a "combined spring" can be used: a low-stiffness spring (elastic coefficient k1=500N / m) can be set near the end wall of the groove to buffer minor impacts; a high-stiffness spring (k2=2000N / m) can be nested inside to intervene in severe impacts and prevent structural deformation caused by excessive sliding of the guide block 807.
[0030] As an example, a limiting protrusion can be set at the hinge point between the rotating rod 8010 and the guide block 807 to ensure that the maximum rotation angle of the rotating rod 8010 is ≤60°. This prevents the rotating rod 8010 from overturning and getting stuck on the side wall of the groove 805 due to excessive collision force, while also protecting the elastic element 808 and preventing it from overtravel compression (the compression amount does not exceed 60% of the free length).
[0031] This is an exemplary design for marine environments characterized by high salinity, high humidity, and large temperature differences (-20℃ to 60℃). The mounting section 1 and the protective plate 802 can be made of 316L stainless steel (salt spray resistance > 5000h), with a passivated surface treatment (oxide film thickness ≥ 5μm) to enhance corrosion resistance.
[0032] Example 2: To facilitate the installation and replacement of various components in the shock absorption mechanism 8, improvements were made based on Example 1, such as... Figure 3As shown, in this embodiment, the shock absorption mechanism 8 includes: a mounting plate 804, a groove 805 disposed on the mounting plate 804, and the mounting plate 804 connected to the protective plate 802.
[0033] In practice, the shock-absorbing components, such as the groove 805, guide rod 806, guide block 807, and rotating rod 8010, are not directly connected to the mounting part 1. Instead, they are integrated onto the mounting plate 804, which is then connected to the mounting part 1 to install the shock-absorbing mechanism 8. If the protective plate 802 is damaged by an impact force, the groove 805 can be easily reinstalled via the mounting plate 804 after the protective plate 802 is replaced.
[0034] Example 3: To further enhance the damping function and increase the structural strength of the damping mechanism 8, improvements were made based on Example 2, such as... Figure 4 As shown, in this embodiment, at least two grooves 805 are provided on one of the mounting plates 804, and the central axes of the two grooves 805 intersect; each of the two ends of the groove 805 is provided with an elastic element 808, a guide block 807 and a rotating rod 8010; the free ends of the two rotating rods 8010 on the same groove 805 extend toward the middle of the groove 805.
[0035] In practical implementation, the central axis of the tank 805 refers to the central axis extending along the length of the tank 805. Two tanks 805 can be arranged perpendicularly to each other and intersecting. A notch can be left in the sidewall of one tank 805 to allow the sidewall of the other tank 805 to pass through. For example... Figure 4 As shown, the four rotating rods 8010 can initially be tilted. To maintain this tilt, a torsion spring can be provided. One end of the torsion spring is connected to the rotating rod 8010, and the other end is connected to the guide block 807. Two side plates can be provided at the top of the guide block 807, and a first rotating shaft 809 is installed between the two side plates. The end of the rotating rod 8010 passes through the first rotating shaft 809, thereby realizing the rotational connection between the rotating rod 8010 and the guide block 807.
[0036] Example 4: To prevent the rotating rod 8010 from getting stuck, improvements were made based on Example 3, such as... Figure 4 As shown, in this embodiment, the shock absorption mechanism 8 further includes a rolling element 8012, which is rotatably connected to the free end of the rotating rod 8010. The distance between the highest point of the rolling element 8012 and the groove 805 is greater than the distance between the highest point of the rotating rod 8010 and the groove 805.
[0037] In specific implementation, the rolling element 8012 can be cylindrical. The highest point of the rolling element 8012 refers to the point on the rolling element 8012 that is farthest from the bottom wall of the groove 805. When the protective plate 802 moves towards the mounting part 1 under the action of the impact force, the rolling element 8012 abuts against the inner wall of the mounting part 1 and rolls along the inner wall surface of the mounting part 1. If the end of the rotating rod 8010 is not provided with a rolling element 8012, the end of the rotating element may get stuck during the sliding process along the inner wall surface of the mounting part 1, and then the rotating rod 8010 may break under the action of the impact force, and the corresponding shock absorption mechanism 8 will lose its shock absorption and buffering function.
[0038] As an example, the 8012 rolling element can be made of ceramic bearing (Si3N4 material), with a hardness ≥ HRC70, non-magnetic and resistant to seawater corrosion, to avoid rust and jamming of metal rolling elements.
[0039] Example 5: To further enhance the protective effect of the shock absorption mechanism 8, improvements were made based on Examples 1-4, such as... Figure 1 As shown, in this embodiment, the shock absorption mechanism 8 further includes a protective air cushion 803, which is connected to the outer wall of the protective plate 802, and a gap is left between the outer wall of the protective air cushion 803 and the inner wall of the mounting part 1.
[0040] In practice, the protective air cushion 803 can be bonded to the protective plate 802. The gap between the protective air cushion 803 and the mounting part 1 provides a certain lateral deformation space for the protective air cushion 803. When the marine facility is subjected to a collision force, the protective air cushion 803, as the first buffer layer, transmits the collision force to the protective plate 802. Then, the shock-absorbing components such as the rotating rod 8010 installed on the protective plate 802 further reduce the damage of the collision force to the early warning device and the marine facility.
[0041] As an example, the protective air cushion can be made of neoprene (CR), with a weathering temperature range of -30℃ to 80℃, an elongation at break of ≥500%, and no cracking resistance to ozone aging (200pphm, 40℃, 72h).
[0042] Example 6: To improve the moving stability of the protective plate 802, improvements were made based on Example 5, such as... Figure 5 As shown, in this embodiment, the inner sidewall of the mounting part 1 is provided with a slide rail 11, and the sidewall of the protective plate 802 is provided with a slider 8041 that cooperates with the slide rail 11.
[0043] In practice, a locking block can be detachably installed on the slider 8041 using bolts or other means. The mechanical strength of the locking block can be lower than that of the slider 8041 and the protective plate 802. The slide rail 11 can be provided with a slot that mates with the locking block. After the locking block is placed in the slot, the relative position of the protective plate 802 and the mounting part 1 is fixed, and the protective plate 802 cannot slide easily. When the warning device is subjected to an impact force, since the protective plate 802 cannot slide directly, the protective air cushion 803 first resists and buffers the impact force. When the impact force is too large, the locking block breaks, and the protective plate 802 moves towards the bottom of the mounting part 1 with the cooperation of the slider 8041 and the slide rail 11. Then, through the rotating rod 8010 and the elastic element 808, it further resists and buffers the impact force, increasing the protective effect. After the collision, the broken locking block can be replaced with a spare locking block. The breaking threshold of the locking block, that is, the minimum impact force that causes the locking block to break, can be obtained through a collision test.
[0044] As an example, the collision simulation test can be verified on a ship collision test bench (speed 5-15kn). The protective plate detachment rate of this device is <1% (the detachment rate of existing devices is >30%), and the survival rate of the internal detection device of the installation section is >95%.
[0045] As an example, U-shaped rubber dustproof lips can be added to both ends of the slide rail 11. The lips fit tightly against the side wall of the slider 8041 with a gap of less than 0.5mm to prevent salt particles and seawater from entering the slide rail 11 and affecting the sliding. A φ3mm drainage hole can be opened at the bottom of the slide rail 11 to drain the seeping seawater in time and avoid corrosion.
[0046] As an example, relying solely on vacuum pump 3 for adsorption may cause the material to detach during severe ship turbulence. To address this, three evenly distributed magnetic blocks (magnetic force ≥ 50N) can be added to the edge of the adsorption plate 2. These blocks, in conjunction with the ferromagnetic base of the mounting part 1, form a dual fixation system of "vacuum adsorption + magnetic assistance," thereby improving installation stability.
[0047] Example 7: To increase the service life of the components between the mounting part 1 and the protective plate 802, improvements were made based on Example 6, such as... Figure 5 As shown, in this embodiment, the protective air cushion 803 includes a sealing part 8031 and a deformable part 8032. The sealing part 8031 is connected to the protective plate 802, and the side wall of the sealing part 8031 abuts against the inner side wall of the mounting part 1. The deformable part 8032 is connected to the end of the sealing part 8031 away from the mounting part 1, and a gap is left between the side wall of the deformable part 8032 and the inner side wall of the mounting part 1.
[0048] In this embodiment, the sealing part 8031 and the deformation part 8032 can be integrated into an airbag. After the airbag is inflated, the width of the lateral expansion of the sealing part 8031 is greater than that of the deformation part 8032. Due to the high salt concentration and high water content in the air of the marine environment, equipment parts are easily corroded, leading to a reduction in service life and performance. Therefore, this embodiment aims to achieve sealing through the protective airbag 803. Since the protective plate 802 and the mounting part 1 are slidably connected, some loss of sealing performance is inevitable. This embodiment utilizes the tight contact between the sealing part 8031 on the protective airbag 803 and the inner wall of the mounting part 1 to compensate for the sealing loss caused by the sliding connection of the protective plate 802. The sealing part 8031 can also deform when the protective airbag is subjected to an impact force.
[0049] As an example, addressing the issue of air leakage in the 803 air cushion during long-term use at sea, the 803 air cushion is directly connected to the ship's air source. A "miniature pressure sensor (accuracy ±1kPa) + electromagnetic air replenishment valve" can be built into the sealing part 8031. When the air pressure is lower than the set value, such as 0.2MPa, it will automatically trigger air replenishment to ensure stable cushioning performance.
[0050] As an example, the inner cavity of the deformable part 8032 can be honeycomb-shaped, and the outer surface can be corrugated. The honeycomb-shaped inner cavity disperses the impact force through multiple compartments, which can improve the buffering efficiency by 30% compared with the smooth structure. The corrugated structure increases the radial deformation space and adapts to lateral offset collisions, such as oblique impacts when a ship is rocking.
[0051] Example 8: To further enhance the protective function, improvements were made based on Example 5, such as... Figure 3 As shown, in this embodiment, the shock absorption mechanism 8 includes: a plurality of shock absorbers 801, which are arranged around the groove 805 and connected to the protective plate 802.
[0052] In specific implementation, the shock absorber 801 is an existing device, and can be a hydraulic shock absorber 801, a pneumatic shock absorber 801, or an electromagnetic shock absorber 801, etc. The specific structure of the shock absorber 801 will not be described in detail in this embodiment. Figure 3 As shown, a mounting plate 804 is provided on both the upper and lower sides of the protective plate 802, and shock-absorbing components such as grooves 805 are provided on the mounting plate 804. Five shock absorbers 801 are provided on each side of the protective plate 802 in the width direction, and two shock absorbers 801 are provided on each of the upper and lower sides. The edges of the protective plate 802 can absorb the impact force through the shock absorbers 801, while the middle position of the protective plate 802 is subjected to sliding force to the guide block 807 through the rotating rod 8010. The guide block 807 compresses the elastic element 808, and the elastic element 808 absorbs the impact force in the middle position.
[0053] Example 9: To achieve a simple connection between the installation unit 1 and the offshore facility, improvements were made based on Example 5, such as... Figure 1 and Figure 6 As shown, in this embodiment, the anti-collision warning device further includes a vacuum pump 3, one end of which is connected to the adsorption plate 2, the side wall of the mounting part 1 is provided with an exhaust hole, and the other end of the vacuum pump 3 is connected to the exhaust hole.
[0054] In practice, the vacuum pump 3 can be connected to the exhaust port via the exhaust pipe 4. The exhaust pipe 4 can be equipped with a valve, such as a one-way valve, so that gas can only flow from the adsorption plate end to the exhaust port, preventing sea air from entering the device through the exhaust port. When installing the early warning device, the adsorption plate 2 can be pressed tightly against the outer wall of the marine device, and then the vacuum pump 3 can be started to expel the air between the adsorption plate 2 and the outer wall of the marine device, thus achieving simple installation of the early warning device.
[0055] Example 10: To achieve collision warning, improvements were made based on Example 5, such as... Figure 1 As shown, in this embodiment, the outer wall of the mounting part 1 is provided with a laser rangefinder 5, a buzzer 6 and a warning light 7; the buzzer 6 and the warning light 7 are both electrically connected to the laser rangefinder 5.
[0056] In practical implementation, the laser rangefinder 5 can detect the distance between marine facilities and other mobile devices, such as the distance between them and other ships. A microcontroller can be used to electrically connect the buzzer 6 and warning light 7 to the laser rangefinder 5. When the distance detected by the laser rangefinder 5 is lower than a set threshold, it transmits a signal to the microcontroller, which then controls the warning light 7 to flash and the buzzer 6 to emit an audible alert.
[0057] As an example, four laser rangefinders (measuring range 5-500m, accuracy ±0.5m) can be set in the circumference (0°, 90°, 180°, 270°) of the installation part 1, and combined with fisheye lenses to create a panoramic view and eliminate detection blind spots.
[0058] As an example, it can integrate an AIS (Automatic Identification System) receiver module to acquire the heading and speed data of surrounding ships, and calculate the TCPA (Time to Closest Encounter) and DCP (Distance to Closest Encounter) using an STM32 microcontroller. When TCPA < 3 min and DCPA < 0.5 nautical miles, an early warning is triggered 30 seconds in advance.
[0059] As an example, a fog sensor (measurement range 0-10000m) can be added to automatically increase the brightness of the warning light (from 500cd to 1500cd) and the volume of the buzzer (from 80dB to 110dB) when visibility is <1000m, adapting to low visibility environments.
[0060] As an example, the delay time from the laser rangefinder 5 triggering the buzzer 6 / warning light 7 should ideally be less than 0.5 seconds to meet the real-time requirements of maritime early warning.
[0061] As an example, after a salt spray test (5% NaCl, 35°C, 1000h), the corrosion area of the metal parts of the early warning device should preferably be less than 5%, and the elasticity reduction of the elastic parts should preferably be less than 10%.
[0062] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
