Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ship early warning devices, in particular to a safety early warning device for a ship. BACKGROUND

[0002] A ship is a vehicle that can navigate or be parked in a water area for transportation or operation, and has different technical performances, equipment and structural types according to different use requirements. A ship will use a pre-warning device during driving to monitor the bridges or other ships encountered during driving to avoid collision. A radar is often used as a safety early warning device for a ship. The radar detects the position, distance and direction of surrounding ships, bridges, land and other objects by emitting electromagnetic waves and receiving reflected signals.

[0003] When a ship sails on the sea, salt (sodium chloride, etc.) in seawater evaporates with sea waves to form salt mist, which adheres to the surface of the radar. Chloride ions (Cl⁻) have strong corrosive properties, which can destroy the oxidation protective layer of the metal surface and cause electrochemical corrosion. Therefore, the salt adhering to the surface of the radar needs to be removed. The existing removal method is to manually periodically scrub the surface of the radar to remove the salt. However, the radar installed on the top of the ship is high, and it is extremely inconvenient for workers to scrub. At the same time, workers need to perform climbing operations, and the ship also shakes, which makes the scrubbing of the surface of the radar have safety hazards. CONTENT OF THE UTILITY MODEL

[0004] In order to improve the problem that there is a certain safety hazard when workers climb to scrub the radar, the present application provides a safety early warning device for a ship.

[0007] By adopting the above technical solution, the water spraying pipe is driven to rotate circularly by the rotating driving member, so that the water spraying openings can comprehensively cover the surface of the radar, thereby effectively removing the salt adhering to the surface of the radar, realizing automatic removal of the salt on the surface of the radar, and compared with the manual scrubbing method, the device does not need workers to perform climbing operations, and avoids the safety hazards caused by the shaking of the ship.

[0008] Preferably, the mounting base has a rotating ring groove, the rotating ring tube is disposed in the rotating ring groove, and the rotating ring tube is provided with a flipping drive component connected to the water spray pipe. The flipping drive component can drive the water spray pipe to rotate so that the water spray pipe can be operably stored in the rotating ring groove.

[0009] By adopting the above technical solution, the rotating ring groove opened on the mounting base provides an installation position for the rotating ring pipe, so that the water spray pipe can be stored in the rotating ring groove when not in use, effectively reducing the space occupied by the water spray pipe in the non-working state and reducing the impact of the water spray pipe on radar detection.

[0010] Preferably, the rotary drive component includes a drive motor, a drive gear, and a driven gear ring. The drive motor is fixedly mounted on the mounting base, the drive gear is coaxially fixedly mounted on the output shaft of the drive motor, and the driven gear ring is fixedly mounted on the rotating ring tube and meshes with the drive gear.

The hinge support and the hinge shaft correspond one-to-one. The hinge shaft is inserted into the hinge support and is rotatably connected to the hinge support.

[0020] Preferably, the width of the water inlet end of the spray nozzle is smaller than the width of the water outlet end, so that the spray nozzle is flared.

[0021] By adopting the above technical solution, the water nozzle is designed in a wide-mouth shape, which can effectively increase the spray range of the water flow, making the water flow more dispersed, thereby increasing the coverage area for salt removal from the radar surface.

[0034] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0035] The inventors of this application discovered that the existing method of manually cleaning the surface of radar 1 is not only inefficient, but also requires operators to climb to a height due to the high installation position of radar 1, posing a significant safety hazard, especially in the swaying environment accompanying ship navigation. Therefore, this application mainly adopts a structural design including radar 1 and mounting base 2, wherein radar 1 is rotatably mounted on mounting base 2, and mounting base 2 is equipped with a rotating ring pipe 3 and a water spray pipe 4. Both ends of the water spray pipe 4 are connected to the rotating ring pipe 3, allowing the water spray pipe 4 to rotate cyclically. Simultaneously, the water spray pipe 4 is connected to a water supply system 6 installed on mounting base 2, and the water spray pipe 4 has several spray nozzles 41 pointing towards radar 1, achieving the effect of automatically removing salt from the surface of radar 1 and avoiding the safety hazards caused by manual climbing.

[0036] This application discloses a safety early warning device for ships.

[0037] Reference Figure 1 A ship safety early warning device includes a radar 1 and a mounting base 2. The mounting base 2 is fixedly installed on the top of the ship, and the radar 1 is installed on the mounting base 2.

[0038] Radar 1 emits high-frequency pulses to the surrounding area. When the electromagnetic waves encounter ships, bridges, or other obstacles, they are reflected and received by the antenna of Radar 1. The target distance is calculated based on the time difference between transmission and reception. The azimuth is determined by the antenna pointing. The Doppler effect is then used to analyze the changes in echo frequency to determine whether the target is stationary (such as a bridge) or moving (such as another ship). Through the ARPA function, multiple targets are automatically tracked, and their positions, speeds, and headings are continuously recorded to predict future trajectories. If the predicted trajectory intersects with the ship's route and the distance / time is below the safety threshold, an early warning is triggered.

[0039] Reference Figure 2 , Figure 3 The mounting base 2 is equipped with a rotating ring pipe 3, a water spray pipe 4, and a rotating drive component 5. The rotating ring pipe 3 has a rectangular cross-section, and the diameter of its inner hole is larger than the maximum diameter of the radar 1. Both ends of the water spray pipe 4 are rotatably connected to the rotating ring pipe 3. The rotating drive component 5 is connected to the rotating ring pipe 3 and drives it to rotate circumferentially. The water spray pipe 4 has a semi-circular shape along its length, so that the trajectory of the water spray pipe 4 as it rotates with the rotating ring pipe 3 is a hemispherical surface of rotation. The radar 1 is located between the surface of rotation formed by the rotation trajectory of the water spray pipe 4 and the mounting base 2. The water spray pipe 4 is connected to a water supply system 6 installed on the mounting base 2.

[0040] Reference Figure 3 , Figure 4The water spray pipe 4 is equipped with several water nozzles 41 facing the radar 1. These nozzles 41 are spaced apart along the length of the water spray pipe 4. Water enters from the inlet end of the nozzle 41 and exits from the outlet end. The width of the inlet end of the nozzle 41 is smaller than the width of the outlet end, making the nozzle 41 flared. This flared design effectively increases the spray range of the water flow, making the water flow more dispersed and thus increasing the coverage area for salt removal from the surface of the radar 1.

[0041] When cleaning radar 1, the rotary drive 5 drives the rotating ring pipe 3 to rotate, and the rotating ring pipe 3 drives the water spray pipe 4 to rotate in a cycle. The water supply system 6 delivers water to the water spray nozzle 41 and sprays it onto radar 1 from the water spray nozzle 41 to clean the salt on the surface of radar 1. The water spray pipe 4 is driven to rotate in a cycle by the rotary drive 5, so that the water spray nozzle 41 can fully cover the surface of radar 1, thereby effectively removing the salt attached to it. This achieves automatic removal of salt from the surface of radar 1. Compared with manual wiping, this device does not require workers to climb to heights, avoiding the safety hazards caused by the ship's rocking.

[0042] Reference Figure 3 , Figure 5 The mounting base 2 has a rotating annular groove 21, and the rotating annular tube 3 is rotatably mounted in the rotating annular groove 21. The rotating annular groove 21 provides rotational support for the rotation of the rotating annular tube 3, improving the stability of the rotation of the rotating annular tube 3. The rotating annular groove 21 leaves space above the rotating annular tube 3 for the insertion of the water spray pipe 4. The top wall of the rotating annular tube 3 is fixedly provided with two sets of hinged supports 22. The two sets of hinged supports 22 are arranged opposite each other along the circumferential rotation of the sliding annular tube. Both ends of the water spray pipe 4 are closed and each is fixedly provided with a hinge shaft 23. The axis of the hinge shaft 23 is arranged along the radial direction of the rotating annular tube 3. The hinge shaft 23 is inserted into the corresponding hinge support 22 and rotatably connected with the hinge support 22. The cooperation between the hinge support 22 and the hinge shaft 23 allows the water spray pipe 4 to rotate relative to the rotating annular tube 3, thereby realizing the flipping action of the water spray pipe 4.

[0043] Reference Figure 1 , Figure 6 The end of the water spray pipe 4 is connected to the rotating ring pipe 3 by a flexible hose 24, so that the water in the rotating ring pipe 3 can enter the water spray pipe 4 through the flexible hose 24. The flexible hose 24 ensures that the water spray pipe 4 can maintain a stable water supply during rotation, avoiding the problem of water supply interruption caused by movement.

[0044] Reference Figure 3 , Figure 5The top wall of the rotating ring tube 3 is equipped with a flipping drive component 7, which includes a rotary motor 71. The rotary motor 71 is a waterproof servo motor, and there is only one rotary motor 71. The rotary motor 71 is fixedly mounted on the rotating ring tube 3. The output shaft of the rotary motor 71 is coaxially and fixedly connected to a hinge shaft 23, so that the rotary motor 71 can drive the water spray pipe 4 to rotate around the hinge shaft 23 and rotate the water spray pipe 4 into the rotating ring groove 21. The water spray pipe 4 can be stored in the rotating ring groove 21 when not in use, which effectively reduces the space occupied by the water spray pipe 4 in the non-working state and reduces the impact of the water spray pipe 4 on the detection of radar 1.

[0045] Reference Figure 3 , Figure 5 and Figure 7 In this embodiment, the rotary drive component 5 includes a drive motor 51, a drive gear 52, and a driven gear ring 53. The drive motor 51 is a waterproof servo motor. A motor mounting slot 54 is provided in the mounting base 2, extending to the side wall of the mounting base 2. The drive motor 51 is fixedly installed in the motor mounting slot 54, with its output shaft facing upwards. The drive gear 52 is coaxially fixedly installed on the output shaft of the drive motor 51. The driven gear ring 53 is fixedly embedded on the outer peripheral wall of the rotating ring tube 3, forming a ring around the outer peripheral wall. The drive gear 52 and the driven gear ring 53 are externally meshed. The drive motor 51 can drive the rotating ring tube 3 to rotate by the meshing of the drive gear 52 and the driven gear ring 53, providing power for the rotation of the rotating ring tube 3. At the same time, the driven gear ring 53 is fixedly installed on the rotating ring tube 3 and meshes with the drive gear 52, realizing the precise drive of the rotating ring tube 3 by the rotary drive component 5.

[0046] Reference Figure 3 The mounting base 2 has a mesh plate 55 at the opening of the motor mounting slot 54. The mesh plate 55 covers the opening of the motor mounting slot 54 and is fixedly connected to the mounting base 2 by bolts. On the one hand, it can dissipate heat from the drive motor 51, and on the other hand, it can prevent foreign objects from entering the motor mounting slot 54.

[0047] Reference Figure 3 , Figure 5 A connecting through hole 31 is provided on the inner circumferential wall of the rotating ring tube 3. The connecting through hole 31 is arranged in a circle along the rotation circumference of the rotating ring tube 3. A sealing ring 32 is provided in the connecting through hole 31 of the rotating ring tube 3. The sealing ring 32 seals the connecting through hole 31. Rubber sealing strips 33 are fixed at both ends of the sealing ring 32. A sealing groove 34 is provided on one side of the rubber sealing strip 33 relative to the end of the rotating ring tube 3. The end of the rotating ring tube 3 is slidably inserted into the sealing groove 34, so that the sealing ring 32 and the rotating ring tube 3 are slidably sealed.

[0048] Reference Figure 3 ,Figure 7 The water supply system 6 includes a water pump 61. A placement groove 62 is provided on the side wall of the mounting base 2. The water pump 61 is installed in the placement groove 62. The suction end of the water pump 61 is connected to the fresh water system through a pipe. The outlet end of the water pump 61 is connected to the rotating ring pipe 3 through a connecting pipe 63. The connecting pipe 63 includes a main pipe 631 nested inside the mounting base 2 and an auxiliary pipe 632. There are two auxiliary pipes 632. The two auxiliary pipes 632 are connected to the end of the main pipe 631. Both auxiliary pipes 632 are fixedly connected to the sealing ring 32 and communicate with the channel inside the rotating ring pipe 3, so that the water pump 61 can supply water to the rotating ring pipe 3 through the main pipe 631 and the auxiliary pipes 632.

[0049] The water pump 61 in the water supply system 6 draws water from the freshwater system and delivers it to the rotating ring pipe 3 via the connecting pipe 63. The water is then delivered to the spray pipe 4 via the flexible hose 24 and finally sprayed out from the spray nozzle 41 to clean the surface of the radar 1. The connecting through hole 31 is arranged in a circle around the circumference of the rotating ring pipe 3, ensuring that the connectivity between the connecting pipe 63 and the rotating ring pipe 3 is not affected during the rotation of the rotating ring pipe 3, thus achieving a stable water supply.

[0050] The implementation principle of a ship safety early warning device according to an embodiment of this application is as follows: When cleaning the radar 1, the rotary motor 71 drives the water spray pipe 4 to rotate out of the rotating ring groove 21 and rotate to a vertical position. Then, the drive motor 51 drives the rotating ring pipe 3 to rotate. The water pump 61 supplies water into the rotating ring pipe 3. The water in the rotating ring pipe 3 enters the water spray pipe 4 along the flexible hose 24 and is sprayed onto the surface of the radar 1 from the water spray nozzle 41, thereby cleaning the salt on the surface of the radar 1 and effectively removing the salt attached to it. This achieves automatic removal of salt from the surface of the radar 1. Compared with manual wiping, this device does not require workers to climb to heights, avoiding the safety hazards caused by ship swaying.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
