Detailed Description

The following is further detailed by way of specific embodiments: as shown in fig. 1-4, the present invention provides a hidden bridge warning indicator, which comprises a box 10, a mounting plate 11, a first guide rail 12, a first slider 13, a bidirectional screw 14, a transmission assembly 20, a driving assembly 30, a power source 40 and a controller 50.

The box body 10 is installed on the bridge 80 and has an open bottom.

The mounting plate 11 is fixedly mounted on the inner wall of the case 10 in the longitudinal direction.

The first guide rail 12 is fixedly mounted on the mounting plate 11 in the longitudinal direction.

The first sliding block 13 is arranged on the first guide rail 12 and is connected with the first guide rail 12 in a sliding mode, and the warning lamp 15 is installed on the first sliding block 13.

The bidirectional screw rod 14 is transversely arranged, two ends of the bidirectional screw rod are rotatably connected with the inner wall of the box body 10, and two thread sections on the bidirectional screw rod 14 are respectively positioned on two sides of the mounting plate 11.

The transmission assemblies 20 have two, and the two transmission assemblies 20 are respectively arranged on two sides of the mounting plate 11. Specifically, the transmission assembly 20 includes a second guide rail 21, a second slider 22, and a connecting rod 23. The second guide rail 21 is fixedly installed on the inner wall of the casing 10 in the lateral direction. The second slider 22 is arranged on the second guide rail 21, and the second slider 22 is connected with the second guide rail 21 in a sliding manner and is also connected with the bidirectional screw 14 in a threaded manner. One end of the connecting rod 23 is hinged with the second slider 22, and the other end is hinged with one side of the first slider 13. When the bidirectional screw 14 rotates, the two second sliding blocks 22 will approach or leave the mounting plate 11 synchronously, and at the same time, the two connecting rods 23 drive the first sliding block 13 to move longitudinally on the first guide rail 12.

The driving assembly 30 includes a first gear 31, a third guide rail 32, a third slider 33, a first rack 34, a first permanent magnet 35, and a first electromagnet 36. The first gear 31 is mounted on the bidirectional screw 14. The third rail 32 is fixedly installed on the inner wall of the casing 10 in the longitudinal direction. The third slider 33 is disposed on the third rail 32 and slidably connected to the third rail 32. The first rack 34 is fixedly mounted on the third slider 33 and is engaged with the first gear 31. The first permanent magnet 35 is fixedly mounted on the top of the first rack 34, and the first electromagnet 36 is fixedly mounted on the top of the third guide rail 32 and is located right above the first permanent magnet 35. When the third sliding block 33 moves up and down, the two-way screw 14 can rotate under the transmission of the first rack 34 and the first gear 31.

The power source 40 and the controller 50 are both fixedly installed on the inner wall of the box body 10, and the controller 50 is electrically connected with the first electromagnet 36.

In normal operation, the two second sliding blocks 22 are located at positions close to the mounting plate 11, and at this time, the first sliding blocks 13 and the warning light 15 are exposed downwards from the bottom of the box body 10, so that light emitted by the warning light 15 can be observed by a boat or a crane.

When extreme weather, such as hail or rainstorm, is encountered, the operator sends a signal to the controller 50 through a remote controller or the like, so that the controller 50 starts to operate. First, the controller 50 energizes the first electromagnet 36, so that the first electromagnet 36 and the first permanent magnet 35 attract each other, and further the third slider 33 is driven to move upwards, and since the first rack 34 is meshed with the first gear 31, the bidirectional screw 14 also rotates. When the bidirectional screw 14 rotates, the two second sliding blocks 22 will be away from the mounting plate 11 synchronously, and at the same time, the two connecting rods 23 drive the first sliding block 13 and the warning light 15 to move upwards. When the connecting rod 23 is in the horizontal state, the first electromagnet 36 stops working, and most of the warning light 15 is shielded by the box body 10, so hail and rainwater are not easy to directly contact the warning light 15, and the invention has better viability preliminarily.

Since the warning device is installed at a high position above the bridge deck or at the bottom of the bridge above the water surface, the driving assembly 30 of the present invention uses the first electromagnet 36 and the first permanent magnet 35 as power sources to drive the respective components to move. Compared with the traditional power sources such as a motor or an air cylinder, the whole weight is greatly reduced, the carrying and the installation of workers are facilitated, otherwise, the installation of a heavier warning indicator on the bridge 80 is extremely difficult. In addition, by virtue of the self-locking capability of the bidirectional screw rod 13, when the connecting rod 23 is in a horizontal state, the first electromagnet 36 only needs to stop working, continuous energization is not needed, and a lot of power supplies are saved.

In one embodiment, two guide assemblies 60 are included, one on each side of the mounting plate 11. The guide assembly 60 includes a first guide plate 61, a second guide plate 62, a second permanent magnet 63, and a second electromagnet 64. The first guide plate 61 is fixedly installed to be inclined on the inner wall of the case 10. The second guide plate 62 is fixedly mounted on the first slider 13 and is parallel to the first guide plate 61. The second permanent magnet 63 and the second electromagnet 64 are oppositely arranged, the second permanent magnet 63 is fixedly installed on the first guide plate 61, and the second electromagnet 64 is fixedly installed on the second guide plate 62 and electrically connected with the controller 50. When the second permanent magnet 63 is located above the second electromagnet 64, the second electromagnet 64 can generate an upward traction force on the second permanent magnet 63.

When the connecting rod 23 is in the horizontal state, the controller 50 energizes the second electromagnet 64, so that the second electromagnet 64 and the second permanent magnet 63 repel each other, and then the first slider 13 is subjected to upward traction force, which is greater than the gravity of the first slider 13 and the warning light 15, and according to the stress analysis, the first slider 13 and the warning light 15 are subjected to upward traction force. Then, the controller changes 50 the direction of the current to the first electromagnet 36, so that the first electromagnet 36 and the first permanent magnet 35 repel each other, and further the third slider 33 moves downward, and the bidirectional screw 14 rotates reversely because the first rack 34 is engaged with the first gear 31. When the bidirectional screw 14 rotates reversely, the two second sliding blocks 22 approach the mounting plate 11 synchronously, and simultaneously, under the action of the two connecting rods 23, the first sliding block 13 and the warning light 15 are driven to move upwards continuously until being completely hidden in the box body 10. Thereby further reducing the possibility of hail and rain coming into direct contact with the warning light 15, further enabling the present invention to have better survivability.

It should be noted that, after the extreme weather such as hail or rainstorm is encountered, the resetting process is opposite to the above steps, and is not described herein again. However, during the resetting process, the second electromagnet 64 is not electrified all the time, and when the connecting rod 23 is in the horizontal state, the downward traction force is obtained by the gravity of the first sliding block 13 and the warning light 15, so that the first sliding block 13 and the warning light 15 are exposed downwards from the bottom of the box body 10.

In one embodiment, two moving assemblies 70 are included, one on each side of the mounting plate 11. The moving assembly 70 is used for driving the second electromagnet 64 on the same side to move along the transverse direction. Specifically, the moving assembly 70 includes a second rack 71, a second gear 72, a fourth guide rail 73, a fourth slider 74, and a third rack 75. The second rack 71 is fixedly installed at the bottom of the second slide block 22 at the same side along the transverse direction. The second gear 72 is installed on an inner wall of the casing 10 and is rotatably connected with the casing 10. The second rack 71 is engaged with the gear, and the fourth rail 73 is fixedly installed on the inner wall of the casing 10 in the lateral direction. The fourth slider 74 is disposed on the fourth rail 73 and slidably connected to the fourth rail 73. The third rack 75 is fixedly installed on the top of the fourth slider 74 in the lateral direction and is engaged with the second gear 72. The second electromagnet 64 on the same side is mounted on a fourth slide 74.

When the two second sliders 22 are synchronously far away from the mounting plate 11, the fourth slider 74 can synchronously approach the mounting plate 11 under the action of the second rack 71, the second gear 72 and the third rack 75, so that the second electromagnet 64 on the fourth slider 74 gradually approaches the second permanent magnet 63, and when the connecting rod 23 is in a horizontal state, the minimum distance between the two is reached. Therefore, when the second electromagnet 64 is electrified, the first sliding block 13 and the warning lamp 15 are subjected to larger upward traction force under the action of the second permanent magnet 63, and the traction effect on the first sliding block 13 is better.

In one embodiment, two bottom plates 16 are provided on each side of the housing 10. One end of the bottom plate 16 is hinged with the bottom of the box body 10, and the bottom plate 16 is connected with the first sliding block 13 through a transmission rod 17. One end of the transmission rod 17 is hinged with the bottom plate 16, and the other end is hinged with the first sliding block 13.

When the first sliding block 13 and the warning light 15 move upwards, the opening at the bottom of the box body 10 is covered by the two bottom plates 16 under the action of the transmission rod 17, so that a closed box body 10 is formed. Due to the protection of the case body 10, hail and rainwater are completely prevented from directly contacting the warning light 15, and the present invention has better survivability.

In one embodiment, the housing 10 is formed with a light transmissive groove 18. The light of the warning lamp 15 can be emitted outward through the light-transmitting groove 18. A light-transmitting plate 19 is arranged in the light-transmitting groove 18, and the light-transmitting plate 19 is made of transparent materials. When the first sliding block 13 and the warning light 15 are completely hidden in the box body 10, the light emitted by the warning light 15 can still be observed by the outside due to the light-transmitting grooves 18 and the light-transmitting plates 19. Therefore, even in extreme weather such as hail or rainstorm, the warning lamp 15 can still work continuously to remind the driver of sailing or driving, and the safety of sailing or driving is further guaranteed.

In one embodiment, each component is made of light materials, so that the overall weight is further reduced, and the carrying and the installation of workers are facilitated.

The foregoing is merely an example of the present invention and common general knowledge of known specific structures and features of the embodiments is not described herein in any greater detail. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the present invention.
