Description

Technical Field

[0001] This utility model relates to the field of navigational aid detection, and in particular to a navigational aid light detection device. Background Technology

[0002] Navigation lights float on the water to guide ships, therefore requiring regular inspection of the light panel and buoyancy to ensure proper functioning. One existing type of electric navigation light detector (CN209014246U) uses a mesh cover connected by a support tube to enclose the navigation light. A push-rod motor drives the mesh cover and the navigation light to vibrate up and down, thus detecting the buoyancy of the light. However, the motor-driven navigation light descends at a constant speed, resulting in a uniform descent onto the water surface, making the buoyancy effect less noticeable. Therefore, a longer time and more tests are needed to make an accurate judgment. Utility Model Content

[0003] The purpose of this application is to provide a navigation light detection device, which aims to solve the problems existing in the prior art.

[0004] This application provides a navigation light detection device, including a housing, an air shaft installed inside the housing, and a winding wheel sleeved on the air shaft. When the air shaft expands, it forms an interference fit with the inner wall of the winding wheel; when the air shaft contracts, it forms a clearance fit with the inner wall of the winding wheel, allowing the winding wheel to rotate relative to the air shaft. A connecting wire is wound on the winding wheel, and the other end of the connecting wire extends from an opening at the bottom of the housing and is fixed to an electric gripper. An electromagnet is fixed next to the opening at the bottom of the housing, and a magnetic block is fixed to the top of the electric gripper.

[0005] Furthermore, a motor is connected to one end of the air shaft.

[0006] Furthermore, a clamping assembly is fixed to one end of the container, and the container can be detachably installed on the ship's side via the clamping assembly.

[0007] Furthermore, the clamping assembly includes a crank plate fixed to one end of the housing. The crank plate is L-shaped and bent downwards. A threaded rod is threadedly connected to the vertical surface of the crank plate, and a pad is rotatably connected to one end of the threaded rod facing the housing.

[0008] Furthermore, the clamping assembly also includes a base plate connected to the bottom of the box via a slot. One end of the base plate is fixed with an inclined brace plate, and the lower end of the brace plate is fixedly connected with a pad block, which can rest against the ship's side.

[0009] Furthermore, a storage battery is installed inside the enclosure, which supplies power to the electric gripper and motor via wires.

[0010] The beneficial effects of this utility model are: after the electric gripper lifts the navigation light to a certain height, the air shaft contracts and the electromagnet is de-energized, causing the navigation light to fall into the water rapidly under the action of gravity. Navigation lights with good buoyancy will rise quickly after falling into the water, while navigation lights that are damaged or leaking will rise only slightly or sink directly after falling into the water, thus helping staff to quickly distinguish between them.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1 The illustrated navigation light detection device includes a housing 1, within which an air shaft 2 is installed. Both ends of the air shaft 2 are rotatably connected to the housing 1. One end of the air shaft 2 is connected to a motor and a reducer, driving the air shaft 2 to rotate slowly. The air shaft 2 and the motor can be connected via a drive belt or directly via a coupling. An air pipe from the air shaft 2 passes through the housing 1 and connects to an external inflation device for inflating the air shaft 2. Alternatively, the air shaft 2 can be driven by an electric or pneumatic cylinder, with an expansion shell that expands outward via a sloping slider, eliminating the need for an inflation device and further saving space in the detection device. Figure 1 and Figure 2As shown, a winding wheel 3 is sleeved on the air expansion shaft 2. When the air expansion shaft 2 expands, it forms an interference fit with the inner wall of the winding wheel 3, allowing the air expansion shaft 2 to rotate and drive the winding wheel 3 to rotate. When the air expansion shaft 2 contracts, it forms a clearance fit with the inner wall of the winding wheel 3, allowing the winding wheel 3 to rotate relative to the air expansion shaft 2. A connecting wire 4 is wound on the winding wheel 3, and the other end of the connecting wire 4 extends from the opening at the bottom of the housing 1 and is fixed to the electric gripper 5. An electromagnet 6 is fixed next to the opening at the bottom of the housing 1, and a magnetic block 7 is fixed to the top of the electric gripper 5. The magnetic block 7 is made of a magnetic material that can be attracted by magnetic force.

[0017] Initially, the electric gripper 5 is fixed to the bottom of the housing 1 by the electromagnet 6, and the connecting line 4 is wound on the winding reel 3. In use, the air shaft 2 expands, causing the winding reel 3 to reverse and release the line. Simultaneously, the electromagnet 6 is de-energized, eliminating the magnetic force, allowing the electric gripper 5 to descend uniformly to the water surface and grasp the navigation light. The air shaft 2 expands, causing the winding reel 3 to rotate clockwise to reel in the line. The electric gripper 5, carrying the navigation light, rises to a certain distance above the water surface. At this point, the air shaft 2 stops rotating and then contracts in diameter. The connecting line 4, under the weight of the electric gripper 5 and the navigation light, causes the winding reel 3 to reverse, allowing the electric gripper 5 and the navigation light to fall freely under gravity. Observing the buoyancy of the navigation light after it falls into the water allows for detection of leaks. For damaged navigation lights, the electric gripper 5 can directly carry the light to the top for easy retrieval by personnel.

[0018] During the ascent of the navigation light carried by the electric gripper 5, the ascent distance can be adjusted as needed, or it can be ascent to the initial height. At this time, the air shaft 2 stops rotating, and the electromagnet 6 is energized to generate magnetic force, which keeps the electric gripper 5 and the navigation light stationary through magnetic force. The air shaft 2 is in a retracted state. When it is necessary to descend, it is only necessary to disconnect the power to the electromagnet 6, and the electric gripper 5 can carry the navigation light down to observe the buoyancy state of the navigation light.

[0019] Normally, the circuit components inside the electric gripper 5 are protected against water and rust to ensure the normal use of the electric gripper 5.

[0020] The housing 1 contains a storage battery, which supplies power to the electric gripper 5, motor, and other electrical devices via wires. A charging port is also provided on the housing 1 corresponding to the storage battery for charging.

[0021] One end of the box 1 is fixed with a clamping assembly, and the box 1 can be detachably installed on the ship's side through the clamping assembly.

[0022] like Figure 1 and Figure 3The clamping assembly shown includes a bend plate 8 fixed to one end of the housing 1. The bend plate 8 is L-shaped and bent downwards. A threaded rod 9 is threadedly connected to the vertical surface of the bend plate 8. A pad 10 is rotatably connected to the end of the threaded rod 9 facing the housing 1. By rotating the threaded rod 9, the distance between the pad 10 and the housing 1 can be changed. In use, the housing 1 is placed outside the ship's side, and the pad 10 is placed inside the ship's side. By rotating the threaded rod 9, the distance between the pad 10 and the ship's side is shortened until the pad 10 is flush with the ship's side, thus fixing the housing 1 to the ship's side.

[0023] The clamping assembly also includes a base plate 11 connected to the bottom of the box 1 via a slot. The bottom of the box 1 has a U-shaped slot, and the base plate 11 has a T-shaped convex rail. The convex rail is inserted into the slot from the side and slides to install the base plate 11 on the box 1. One end of the base plate 11 is fixed with an inclined brace plate 12, and the lower end of the brace plate 12 is fixedly connected with a pad 10. When the box 1 is installed on the ship's side, the pad 10 can abut against the ship's side to support the box 1 and keep it stable.
