[0020] To make the technical problems, technical solutions, and beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] As shown in Figures 1 to 3, this embodiment discloses a bridge anti-ship collision device, including poles 1 erected on both sides of a river channel. One pole 1 is equipped with a laser transmitter 2, and the other pole 1 is equipped with a laser receiver 3. The laser transmitter 2 and the laser receiver 3 are located at the same height. The laser receiver 3 can continuously receive the signal from the laser transmitter 2. When an oversized ship blocks the laser signal, causing the laser receiver 3 to be unable to receive the laser signal, the laser receiver 3 outputs an alarm signal to the controller 4. The controller 4 issues an alarm message through a voice alarm unit 5.

[0022] Laser emitter 2 and laser receiver 3 are respectively housed in corresponding dustproof instrument housings 6, which are fixedly mounted on pole 1. The dustproof instrument housing 6 includes a housing 601, a cavity interlayer 602 in the housing wall, an air pipe 603 on the outer side of the housing 601, an air inlet end of the air pipe 603 connected to an air source device, and an air outlet end of the air pipe 603 connected to the cavity interlayer 602. An inner protective cover 604 is provided on the outer wall of the housing 601 corresponding to the laser receiver 3 or the laser emitter 2. The inner end of the inner protective cover 604 is connected to the interior of the housing 601, and a transparent lens 605 is provided on the outer end of the inner protective cover 604. An outer protective cover 606 is provided around the outer side of the inner protective cover 604 and is fixed to the outer wall of the housing 601. Several air holes 607 are opened on the outer wall of the housing 601 in the area enclosed by the outer protective cover 606, and the air holes 607 are connected to the cavity interlayer 602.

[0023] During operation, the air source switch button controls the opening and closing of the air source passage by controlling the solenoid valve. Air tube 603 continuously blows air into the cavity interlayer 602, and the high-speed gas is finally discharged through the air vent 607, preventing dust from affecting the laser transmitter 2 and laser receiver 3. Simultaneously, in hot summer weather, the gas in the cavity interlayer 602 is circulating, which effectively reduces the temperature of the dustproof instrument housing 6, preventing the laser transmitter 2 and laser receiver 3 from operating in a high-temperature environment for extended periods.

[0024] In this embodiment, a wiper cleaning device 7 is provided on one side of the inner cover 604. The wiper cleaning device 7 includes a motor 701 and a spray head 702. The motor 701 is mounted and fixed on the dustproof instrument housing 6. A wiper 703 is provided on the rotating shaft of the motor 701 and the wiper 703 contacts the transparent lens 605. The spray head 702 is located below the transparent lens 605 and is mounted and fixed on the outer cover 606.

[0025] In this embodiment, the dustproof instrument housing 6 is equipped with two laser emitters 2 or two laser receivers 3. This creates two sets of laser beams on both sides of the river, which effectively ensures signal accuracy and automatically eliminates interference from leaves and birds. The motor 701 that drives the wiper 703 is installed between the two laser emitters 2 or the two laser receivers 3, so that one wiper 703 can clean both laser emitters 2 or the two laser receivers 3.

[0026] In this embodiment, a solar panel 8, a battery 9, and a monitoring camera 10 are installed on the pole 1. The solar panel 8 generates electricity and stores it in the battery 9, which then powers all the electrical equipment on the pole 1. The monitoring camera 10 can photograph and collect evidence of oversized vessels.

[0027] As shown in Figures 1 and 4, the bridge anti-ship collision device in this embodiment also includes an anti-collision energy-absorbing device 11, which is disposed on the side of the bridge 12. The anti-collision energy-absorbing device 11 includes a steel box 1101, in which an energy-absorbing filler 1102 is disposed. One end of the steel box 1101 is provided with a plug 1103, and the other end is provided with a slot 1104. Adjacent plugs 1103 and slots 1104 are inserted and engaged and fixed by pins. The plastic deformation of the anti-collision energy-absorbing device 11 further absorbs the impact energy, reduces the impact of ships on the bridge, and reduces the damage to the bridge caused by the impact.

[0028] In this embodiment, the energy-absorbing filler 1102 is polyurethane foam.

[0029] In this embodiment, as shown in Figure 1, an LED height restriction light 13 is also included. The LED height restriction light 13 is installed on the side of the bridge 12 and is electrically connected to the controller 4. When the ship exceeds the height limit, the controller 4 controls the LED height restriction light 13 to display frequently to remind the ship's navigator.

[0030] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
