[0002] With the rapid development of inland water transport and road traffic, the risk of collision between navigable ships and bridges during navigation continues to increase, and there are great safety hazards of ship collision with bridges. In recent years, major ship collision accidents have continued to increase, among which the damage and accidents caused by ship deviation account for about 80%. Severe bridge collision accidents have brought huge economic losses to the normal operation of bridges, and also caused serious pollution to the marine environment. Therefore, it is urgent to establish a device to prevent bridge-ship collision to ensure the safety of bridges, especially to solve the impact of yawed ships on bridge safety during navigation, and eliminate the hidden dangers of ship collision accidents from the root.

DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0033] like Figure 1-10 As shown, an intelligent bridge anti-collision monitoring system includes a bridge body 1 and a pier body 10, a navigation hole is formed between the two pier bodies 10 and the lower side of the bridge body 1, a central processing unit, an early warning radar 17, a laser light 18 and an acoustic and light alarm 19 are installed on one side of the bridge body 1, the central processing unit includes a data processing module, a control module, and a wireless concentric module, the early warning radar 17, the laser light 18 and the acoustic and light alarm 19 are installed side by side on the lower side of the bridge body 1, the early warning radar 17 is electrically connected to the central processing unit, the laser light 18 is electrically connected to the central processing unit, and the acoustic and light alarm 19 is electrically connected to the central processing unit;

[0034] The early warning radar 17 monitors the ships in real time, records the speed and direction of the ships in real time, and gives sound and light alarms through the sound and light alarm 19 and the laser light 18 to warn the ships that deviate from the waterway and whose speed does not meet the regulations. The wireless communication module in the central processor transmits the information to the control center in real time.

[0035] During the use of the present invention, when a ship is passing normally, the laser light 18 and the early warning radar 17 guide the passing ships. When the early warning radar 17 detects that the ship has a tendency to deviate from the channel, the sound and light alarm 19 reminds the ship through flashing lights and voice, and the laser light 18 flashes synchronously to remind the deviating ship, thereby avoiding accidents and ensuring the safety of the pier body 1.

[0036] Furthermore, when there is no need to guide or warn the ship, the laser light 18 and the bridge light together form a bridge lighting effect, making the bridge more attractive at night.

[0037] The present invention monitors the passing ships in real time through early warning radar, laser lights and sound and light alarms, and warns ships that deviate from the waterway through sound and light alarms and laser lights, ensuring that the ships travel within the waterway and the safety of the bridge pier body.

[0038] A bridge intelligent anti-collision warning device, which is suitable for the above-mentioned bridge intelligent anti-collision monitoring system; it includes a bridge body 1 and two pier bodies 10, the bridge body 1 is installed on the upper side of the two pier bodies 10, and the lower sides of the two pier bodies 1 are slidably equipped with protective platforms 11, and the two protective platforms 11 are each provided with an arc cavity 12, and a plurality of hydraulic rods 13 distributed in a circumference are fixedly arranged in the two arc cavities 12, and a plurality of first springs 14 matching the hydraulic rods 13 are fixedly arranged in the two arc cavities 12, and both ends of the plurality of first springs 14 are in contact with the inner and outer side walls of the arc cavity 12, and two beacon lights 15 symmetrically distributed in the front and back are fixedly arranged on the upper sides of the two protective platforms 11, and two cameras 16 symmetrically distributed in the left and right are installed on the lower side of the bridge body 1, and two protective shells 63 symmetrically distributed in the left and right are fixedly arranged on the lower side of the bridge body 1, and a control component is provided between the two protective platforms 11 and the corresponding cameras 16;

[0039] The camera 16 in the present invention is electrically connected to the central processor. During use, the navigation light 15 guides the ship passing through the navigation hole to ensure that the ship passes through the navigation hole. The camera 16 monitors a place at a certain distance from the pier body 10 in real time to ensure that the ship is traveling within the channel. The camera 16 takes pictures of the ship that deviates from the channel and uploads them to the control center to ensure the safety of the pier body 1.

[0040] When the present invention is in use, the interior of the protection platform 11 is a sealed space, which provides buoyancy for the protection platform 11. The hydraulic rod 13 and the first spring 14 absorb and buffer the impact force received by the side wall of the protection platform 11, thereby preventing the impact force from being transmitted to the pier body 10, thereby ensuring the integrity of the pier body 10.

[0041] During use, the present invention adjusts the tilt angle of the camera 16 through the control component, so that the camera 16 always keeps monitoring a position at a certain distance from the pier body 1 as the water level changes, ensuring that the warning of passing ships is not affected by the water level change, thereby ensuring the safety of the pier body 1;

[0042] The present invention installs a protective platform on the lower side of the pier body in a sliding manner. The protective platform slides on the surface of the pier body along with the water level, thereby protecting the pier body in real time. Two cameras are used to monitor passing ships in real time, and ships that deviate from the route are reminded by sound and light alarms, thereby greatly avoiding the occurrence of accidents.

[0043] The control component includes a fixed rod fixed on the lower side of the bridge body 1, and a wire wheel 20 is coaxially rotated on the fixed rod. A coil spring 21 is fixed between the inner wall of the wire wheel 20 and the side wall of the fixed rod. A pull rope 22 is wound around the side wall of the wire wheel 20. One end of the pull rope 22 is fixedly connected to the side wall of the wire wheel 20, and the other end of the pull rope 22 is fixedly connected to the upper side of the protective platform 11. A first circular shaft 23 is rotatably mounted on the lower side of the bridge body 1, and a first bevel gear 24 is coaxially fixedly disposed on one side of the first circular shaft 23. A second circular shaft 25 is coaxially fixedly disposed on the front side of the wire wheel 20, and a second bevel gear 26 is coaxially fixedly disposed on the front side of the second circular shaft 25.

A fan-shaped plate 28 is fixedly disposed on the rear side of the camera 16, and a plurality of tooth grooves 29 matching the first gear 27 are provided on the side wall of the fan-shaped plate 27.

[0044] During the use of the present invention, when the protection platform 11 does not slide up and down, the reel 20 always keeps the pull rope 22 tight due to the elasticity of the coil spring 21, and the camera 16 is in a disabled state, so that the camera 16 can monitor the waterway in real time;

[0045] When the present invention is used, when the protection platform 11 moves, the up and down movement of the protection platform 11 pulls the pull rope 22, and the pull rope 22 cooperates with the coil spring 21 to drive the wire wheel 20 to rotate, and the wire wheel 20 thereby drives the second circular shaft 25 to rotate, and the second circular shaft 25 synchronously drives the second bevel gear 26 to rotate, and the second bevel gear 26 synchronously drives the first bevel gear 24 to rotate, and the first bevel gear 24 synchronously drives the first circular shaft 23 to rotate, and the first circular shaft 23 synchronously drives the first gear 27 to rotate, and the first gear 27 drives the fan-shaped plate 28 to rotate through the tooth groove 29, and the fan-shaped plate 28 drives the camera 16 to rotate, so that the camera 16 always monitors the waterway at a certain distance from the pier body 1 to ensure the safety of the pier body 1;

[0046] Furthermore, wire lights are installed inside the pull rope 22, and the course of the ship is guided by the wire lights on both sides, so that the ship can observe the distance between the pier bodies 10 on both sides.

[0047] A protective cover 30 is fixedly provided on the lower side of the bridge body 1, a protective cover 31 is rotatably mounted on the lower side of the protective cover 30, a first round rod 32 is rotatably mounted between the protective cover 30 and the protective cover 31, and a control member matching the first round rod 32 is provided on the lower side of the bridge body 1;

[0048] The control member includes a first disc 33 installed concentrically on one side of the first round rod 32, a second round rod 34 is slidably mounted on the lower side of the bridge body 1, a second round rod 35 matching the first round disc 33 is fixedly arranged on one side of the second round rod 34, a plurality of first limiting blocks 36 distributed in a circumference are fixedly arranged on the second round disc 35 close to the first round disc 33, the first round disc 33 is provided with a plurality of limiting openings 37 matching the first limiting blocks 36, and a transmission member is arranged between the first round shaft 23 and the second round rod 34;

[0049] When the present invention is used, as the water level rises significantly and the protective platform 11 rises, the first circular shaft 23 drives the second circular rod 34 to rotate through the transmission member, and the second circular rod 34 drives the second circular disk 35 to rotate, and the first limit block 36 on the side wall of the second circular disk 35 engages with the limit opening 37, and the second circular disk 35 drives the first circular disk 33 to rotate, and the first circular disk 33 synchronously drives the first circular rod 32 to rotate, and the first circular rod 32 thereby drives the protective cover 31 to rotate, so that the protective cover 31 protects the early warning radar 17, the laser light 18 and the sound and light alarm 19 in the protective cover 30 to avoid damage.

[0050] The transmission member includes a first cylinder 40 rotatably assembled on the front side of the bridge body 1 and matched with the second round rod 34, a plurality of first clamping blocks 41 distributed in a circumference are fixedly arranged on the side wall of the second round rod 34, a plurality of first clamping grooves matching with the first clamping blocks 41 are opened on the inner wall of the first cylinder 40, a second gear 42 is coaxially fixedly arranged on one side of the first circular shaft 23, and a third gear 43 meshing with the second gear 42 is coaxially fixedly arranged on the side wall of the first cylinder 40;

[0051] During the use of the present invention, when the protective platform 11 moves, the first circular shaft 23 synchronously drives the second gear 42 to rotate, the second gear 42 drives the third gear 43 to rotate, the third gear 43 synchronously drives the first cylinder 40 to rotate, the first cylinder 40 drives the second circular rod 34 to rotate through the first card slot and the first card block 41, and the second circular rod 34 drives the first circular disc 33 to rotate through the second circular disc 35, thereby controlling the closing of the protective cover 31 to protect the internal electronic components.

[0052] A moving part matching the second round rod 34 is provided on the lower side of the bridge body 1, and the moving part includes a screw rod 44 rotatably assembled on the lower side of the bridge body 1, a fourth gear 45 meshing with the second gear 42 is coaxially fixedly provided on one side of the screw rod 44, a connecting rod 46 matching the screw rod 44 is rotatably assembled on the side wall of the second round rod 34, and a threaded hole matching the screw rod 44 is opened on the front side of the connecting rod 46;

[0053] During the use of the present invention, when the protection platform 11 moves up and down, the first circular shaft 23 rotates to drive the second gear 42 to rotate, the second gear 42 synchronously drives the third gear 43 and the fourth gear 45 to rotate, the fourth gear 45 synchronously drives the screw 44 to rotate, the screw 44 synchronously drives the connecting rod 46 to move, and the connecting rod 46 drives the second circular rod 34 to move, so that the second circular disc 35 on one side of the second circular rod 34 fits and separates from the first circular disc 33. No other electrical components are used in this device, and the protective cover 31 is closed by the lifting and lowering of the protection platform 11, which greatly saves the use cost;

[0054] Furthermore, when the water level rises to a certain height and the protective platform 11 rises to a certain height, the connecting rod 46 drives the second round rod 34 to move a certain distance before the second disc 35 fits with the first disc 33, thereby controlling the protective cover 31 to close and ensuring the smooth use of the device.

[0055] A plurality of second slots 50 distributed in a circumference are provided on the side wall of the first round rod 32, and second blocks matching the second slots 50 are fixedly provided on the inner side walls of the two first discs 33, and second cylinders 51 matching the first discs 33 are fixedly provided on the left and right sides of the protective cover 30, and second springs 52 are fixedly provided between the side walls of the two second cylinders 51 and the side walls of the two first discs 33, and an annular disk 53 is fixedly provided on the side of the two cylinders 51 close to the first disc 33, and a plurality of second stop blocks 54 matching the stop opening 37 are fixedly provided on the side of the two annular disks 53 close to the first disc 33;

When the second disc 35 abuts against the first disc 33, the first disc 33 is pushed toward the protective cover 30. One side moves to compress the second spring 52. After the first limiting block 36 is inserted into the limiting opening 37, the second disc 35 drives the first disc 33 to rotate. After the first disc 33 drives the protective cover 31 and the protective cover 30 to close through the second clamping block and the second clamping groove 50, the first disc 33 fits with the annular disc 53. The second limiting block 54 and the first limiting block 36 are simultaneously inserted into the limiting opening 37 to limit the first disc 33, thereby preventing the first disc 33 from rotating autonomously and protecting the electronic equipment inside the protective cover 30.

[0057] When the present invention is used, when the protection platform 11 descends, the second disc 35 moves away from the first disc 33 during the rotation process. Under the elastic action of the second spring 52, the first disc 33 is separated from the second limit block 54 on the side wall of the annular disc 53, and the protection cover 31 rotates autonomously, thereby driving the first disc 33 to rotate, so that the electronic equipment inside the protection cover 30 can work normally, ensuring normal guidance of the ship.

[0058] The left and right side walls of the first round rod 32 are fixed with limit plates matching the first disc 33, and the two second discs 35 are both provided with circular grooves 61 matching the limit plates 36; when the second disc 35 approaches the first disc 33, the first round rod 32 penetrates into the second round rod 34 to ensure the normal use of the device.
