Description

Technical Field

[0001] This utility model belongs to the technical field of navigational beacon bodies, and specifically relates to a convenient fixing device for navigational beacon bodies. Background Technology

[0002] Navigational markers are aids to safe navigation, and inland waterway markers are most commonly buoys (mounted on marker vessels). Currently, the buoy's feet are secured to the marker vessel by wire. However, due to factors such as ship collisions, changes in water conditions, and natural corrosion, the buoy and marker vessel are frequently disassembled. This traditional method of fixing increases the workload for on-site maintenance personnel. For example, a main waterway with a maintenance length of 196 km and more than 360 buoys, maintained at five different locations, necessitates the adoption of convenient fixing devices to address these issues. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a convenient fixing device for navigation beacon bodies, which is simple and convenient to operate and greatly reduces the workload of grassroots navigation beacon maintenance personnel.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A convenient fixing device for a navigation beacon includes a top rod guide rail and a center plate. The top rod guide rail and the center plate form a fixing base. The center plate is rotatably engaged with the central column of the thrust disc. The central column of the thrust disc is connected to the thrust disc through a connecting rod. The thrust disc is provided with a strip-shaped hole. A ratchet is provided on the central column of the thrust disc. The ratchet is matched with a pawl, and the pawl is connected to the pawl handle and the pawl column. The push rod guide rail is connected to the push rod via push rod pins.

[0005] Preferably, the center plate has a square structure, and the four corners of the center plate are respectively connected to the top rod guide rail.

[0006] Preferably, the fixing base is welded to the deck of the marker ship.

[0007] Preferably, the center plate has a circular hole, in which a ball bearing is installed, and the central column of the thrust disk passes through the ball bearing and can rotate around its own axis.

[0008] Preferably, a push rod pin is fixed at the end of the push rod, and a groove is provided on the side of the push rod guide rail near the central column of the thrust disk. The push rod pin is slidably disposed in the groove and is slidably disposed in the strip hole.

[0009] Preferably, there are multiple connecting rods arranged in a ring around the central column of the thrust disk, and the number of strip holes is the same as the number of top rods.

[0010] Preferably, the upper part of the central column of the thrust disk is provided with a stepped key and a keyway adapted to the stepped key, and the inner diameter of the ratchet is provided with a groove adapted to the stepped key. The stepped key is embedded in the groove of the ratchet to realize the synchronous rotation of the central column of the thrust disk and the ratchet.

[0011] Preferably, the pawl post is welded to the center plate, the pawl post and the pawl are rotatably engaged, and the pawl is welded to the pawl handle; The pawl and the pawl post are connected by an elastic element.

[0012] Preferably, the device further includes a thrust disc handle, which is connected to the central column of the thrust disc via a handle base.

[0013] Preferably, rotating the pawl handle separates the pawl from the ratchet, pushing the push disc handle to drive the push disc center column, ratchet, and push disc to rotate synchronously. When the push disc rotates, it pushes the push rod pin to slide along the groove through the strip hole, thereby driving the push rod to extend and pass through the holes of the four legs of the lamp holder and abut against the angle steel; rotating the pawl handle back makes the pawl engage with the ratchet to lock the push disc center column.

[0014] The present invention can achieve the following beneficial effects: This utility model requires no other facilities or major modifications to the marker boat and light frame. It has a simple structure and uses modern and mature installation techniques, making it easy to install. This invention cleverly utilizes the characteristics of a ratchet to achieve one-click operation for fixing the navigation light frame through mechanical transmission. Specifically, a pawl post is installed on the center plate, and the two are fixed by welding. A pawl and its handle are located at the top of the pawl post. When the pawl handle is turned, the ratchet is released, pushing the disc handle. The central post of the disc rotates, causing the ratchet and the thrust disc to rotate. The rotation of the thrust disc pushes the push rod pin outward. The push rod extends and passes through the four feet holes at the bottom of the light frame, abutting against the angle steel installed on the beacon boat. Turning the ratchet handle back locks the ratchet, thus achieving one-click fixing of the light frame. This invention is simple and convenient to operate, greatly reducing the workload of grassroots navigation light maintenance personnel. Attached Figure Description

Detailed Implementation

[0017] The existing marker vessel's hull 14 consists of two parts: a lower light frame and a top signal device. The light frame is a steel structure with four legs. The marker vessel's deck has angle steel members corresponding to the four legs of the light frame, positioned precisely around and adjacent to them. These four angle steel members are welded to the marker vessel's deck. Appropriately sized holes are provided in the four legs of the light frame to allow the top rod to pass through smoothly; however, the holes should not be too large to avoid instability caused by the marker vessel's swaying.

[0018] Preferred solutions include Figures 1 to 6 As shown, a convenient fixing device for a navigation beacon includes a top rod guide rail 1, a center plate 2, a thrust disc center column 4, a thrust disc 7, a ratchet 8, a pawl column 9, a pawl handle 10, a thrust disc handle 11, a top rod pin 12, and a top rod 13.

[0019] The top rod guide rail 1 is fixedly connected to the center plate 2 and the two are welded together to the deck 16 of the hull of the marker ship.

[0020] A circular hole is provided in the center of the center plate 2, and a ball bearing is installed in the circular hole. The central column 4 of the thrust disk passes through the ball bearing and can rotate around its own axis. Specifically, a circular hole slightly larger than the diameter of the central column of the thrust disk is cut in the center of the center plate 2, and a ball bearing is installed therein, so that the central column of the thrust disk can stand on the central circular hole of the disk and rotate smoothly.

[0021] The top rod 13 is fixed with a top rod pin 12 at its end. The top rod guide rail 1 has a groove on the side near the central column 4 of the thrust disk, and the top rod pin 12 is slidably disposed in the groove. The thrust disk 7 is sleeved on the outside of the central column 4 of the thrust disk. The thrust disk 7 has four arc-shaped slots, which are adapted to the top rod pin 12 and the top rod pin 12 passes through the slots. Specifically, the size of the slots is adapted to the top rod pin, preferably by casting as a single piece. The slots are arc-shaped on the thrust disk to facilitate the sliding of the top rod pin as the thrust disk rotates. The thrust disk and the top rod guide rail are not connected and fixed. Four diagonal bracing connecting rods are provided between the disk part of the thrust disk and the central column. The upper part of the bracing is welded and fixed to the central column, and the lower part is welded and fixed to the inner circle of the thrust disk.

[0022] The upper part of the thrust disc central column 4 is provided with a stepped key and a keyway 5 adapted to the stepped key.

The stepped key is embedded in the groove of the ratchet 8 to achieve synchronous rotation of the thrust disc central column 4 and the ratchet 8. Specifically, the upper part of the thrust disc central column is provided with a stepped key and keyway. The stepped key is embedded in the central column of the disc. The inner diameter of the ratchet is provided with a groove adapted to the upper section of the stepped key. By the stepped key being engaged in the groove of the ratchet's inner diameter, the ratchet and the thrust disc central column are fixedly connected. This allows the ratchet to rotate synchronously when the central column of the disc rotates, and the ratchet is easy to disassemble and replace if damaged.

[0023] A thrust disc handle is installed at the lower end of the step key. The thrust disc handle is welded to the central column of the disc, and the handle is connected to the handle base by a flexible bolt, so that the handle can rotate.

[0024] A pawl post 9 is welded onto the center plate 2. A pawl is provided on the top of the pawl post 9. The pawl handle 10 is connected to the pawl.

[0025] The selection of elastic elements should include at least the following two: The first type has a round hole on the pawl, which is connected to the pawl post 9 by a torsion spring or a clockwork.

[0026] The second type, such as Figure 7 , 8 As shown, an L-shaped rod is welded onto the pawl post 9, and the L-shaped rod is connected to the pawl via a tension spring.

[0027] The thrust disc handle 11 is connected to the thrust disc center column 4 via the handle base; rotating the pawl handle 10 can separate the pawl from the ratchet 8, and pushing the thrust disc handle 11 can drive the thrust disc center column 4, the ratchet 8 and the thrust disc 7 to rotate synchronously. When the thrust disc 7 rotates, it pushes the top rod pin 12 to slide along the groove through the strip hole, thereby driving the top rod 13 to extend and pass through the holes of the four legs of the lamp holder and abut against the angle steel; turning the pawl handle 10 back can make the pawl engage with the ratchet 8 to lock the thrust disc center column 4.

[0028] Furthermore, the four top rod guide rails 1 and the center plate 2 are integrally cast.

[0029] Furthermore, the thrust disk 7 and the four arc-shaped slots are integrally cast.

[0030] Furthermore, four diagonal bracing connecting rods 3 are provided between the thrust disk 7 and the central column 4 of the thrust disk. The upper part of the diagonal bracing connecting rod 3 is welded and fixed to the central column 4 of the thrust disk, and the lower part is welded and fixed to the inner circle of the thrust disk 7.

[0031] Furthermore, the groove length on the push rod guide rail 1 is such that the push rod pin 12 is located within the groove when the push rod 12 is fully extended or retracted.

[0032] Furthermore, the thrust disc handle 11 is connected to the handle base by a hinged bolt, and the thrust disc handle 11 can rotate around the hinged bolt.

[0033] Furthermore, the lamp holder is a steel structure, and the welding positions of the angle steel to the 16th deck of the marker ship correspond one-to-one with the positions of the four legs of the lamp holder.

[0034] Furthermore, the end of the top rod 13 is a planar structure, and when the top rod 13 abuts against the angle steel, the planar structure is completely in contact with the side of the angle steel.
