Description

Technical Field

[0001] The utility model belongs to the technical field of civil engineering, and in particular relates to a ship collision prevention alarm device for a wading bridge. Background Art

[0002] Anti-collision work on highway water-crossing bridges can effectively reduce accidents caused by ships colliding with bridges and protect bridge structures from damage. By setting up anti-collision facilities, it can reduce casualties and economic losses caused by bridge damage, extend the service life of bridges and reduce maintenance costs.

[0003] A common anti-collision device for highway bridges with water is a fixed pier anti-collision device. This device is tightly connected to the pier foundation or column. Its cushioning properties can dissipate most of the impact force when a vessel collides with the bridge foundation or column, protecting the bridge's stability. However, the disadvantages of fixed pier anti-collision devices are as follows:

[0004] (1) Fixed pier anti-collision facilities have limited adaptability to water levels. Fixed pier anti-collision facilities cannot automatically adjust their height as the water level changes. Therefore, their protective effect will be affected when the water level changes in different seasons.

[0005] (2) The installation of fixed pier anti-collision facilities is difficult. The installation of fixed pier anti-collision facilities is usually complicated and requires consideration of the connection method with the pier. It also requires underwater operations to ensure that the fixed pier anti-collision facilities can be firmly fixed. In addition, the installation of fixed pier anti-collision facilities may require the modification or reinforcement of the pier column, which increases the difficulty of the project.

[0006] (3) Fixed pier anti-collision facilities are difficult to maintain. Since fixed pier anti-collision facilities are installed on the piers of wading bridges that intersect with the water surface, they are difficult to maintain once installed, especially when the facilities are damaged and need to be replaced or repaired.

[0007] (4) Fixed pier anti-collision facilities lack flexibility. Once installed, fixed pier anti-collision facilities are difficult to adjust or move, and their flexibility is relatively poor for different types of collision threats that may arise in the future.

[0008] Fixed bridge pier anti-collision devices have little warning function. They cannot warn ships about to collide with bridge piers and cannot prevent collisions; they can only reduce the damage caused by collisions. Utility Model Content

[0009] In response to the problems existing in the above-mentioned prior art, the utility model provides a water-related bridge anti-ship collision alarm device, the purpose of which is that the alarm device can float on the designated water surface area set by the operator through a floating main body. Even if the water level changes in different seasons, the alarm device will not be affected due to its floating characteristics. It has good adaptability to water levels, monitors passing ships through cameras, and issues different degrees of alarms to ships that may collide through a control chip, so as to provide early warning and facilitate maintenance.

[0010] In order to achieve the above purpose, the specific solutions of the present utility model are as follows:

[0011] The anti-ship collision alarm device for a wading bridge includes a floating body, an anchor, an audible and visual alarm, a camera, a loudspeaker and an equipment box installed on the floating body. The anchor is connected to the bottom of the floating body by a binding rope. The floating body is semi-enclosed. The audible and visual alarm is installed on the top of the equipment box, the camera is installed on one side of the top of the equipment box, and the loudspeaker is installed on the equipment box.

[0012] Furthermore, flexible nets are respectively installed on both sides of the opening of the floating body.

[0013] Furthermore, it includes a control chip, a GPS module, an NBIOT module and a power supply, and the control chip, GPS module, NBIOT module and power supply are respectively arranged in the equipment box, the GPS module, NBIOT module, sound and light alarm, camera and speaker are respectively connected to the control chip, and the power supply provides working voltage for the control chip, sound and light alarm, camera and speaker.

[0014] Furthermore, it also includes a terminal device, which is connected to the NBIOT module and is a mobile phone, computer or laptop.

[0015] Furthermore, the floating body is C-shaped, and both sides of the opening of the floating body extend outwards respectively.

[0016] Advantages of the present invention

[0017] (1) The anti-ship collision warning device for wading bridges of the present invention only requires the operator to transport it to the designated water surface area by ship and drop the anchor to the bottom of the water to complete the installation. When the installation is completed, it can be fixed in the set water surface area by the anchor. When it is necessary to adjust the position or move to support other wading bridges, the anchor can be pulled up and it can be moved flexibly. The floating body floats on the designated water surface area set by the operator. Even if the water level changes in different seasons, due to the floating characteristics, the device will not be affected and has good adaptability to the water level.

[0018] (2) The alarm device is easy to maintain. When a fault occurs or maintenance is required, the operator only needs to board the floating body to perform maintenance and replacement, without the need to perform construction work in the water.

[0019] (3) The warning device monitors the passing ships through cameras and issues different levels of warnings to ships that may collide through the control chip, so as to provide early warning and minimize the occurrence of incidents. Even if a collision occurs, it can effectively mitigate the damage caused by the collision. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The GPS module 2, NBIOT module 3, sound and light alarm 1, camera 4, and speaker 7 are each connected to a control chip 5. The sound and light alarm 1 determines whether to initiate an alarm based on the sound and light alarm instructions from the control chip 5. The GPS module 2 acquires the geographic location of the floating object 8. The video signal from the camera 4 is processed by the control chip 5, which then transmits the sound and light alarm instructions and the geographic location of the floating object 8. The speaker 7 receives the control instructions from the control chip 5 and determines whether to issue a high-decibel alarm. A terminal device is connected to the NBIOT module 3. The terminal device can be a mobile phone, computer, or laptop. A power supply 6 provides operating voltages for the control chip 5, sound and light alarm 1, camera 4, and speaker 7.

[0037] Working principle:

[0038] During use, the operator places the floating body 8 on the water surface in front of the pier of the wading bridge, and then drops the anchor 9 to the bottom of the water, so that the floating body 8 can be fixed on the preset water surface. When the camera 4 captures a ship about to collide with the floating body 8, the video data is sent to the control chip 5. The control chip 5 analyzes the video data transmitted by the camera 4 and, based on the distance between the ship and the floating body 8, sends a command to control the sound and light alarm 1 or sends a command to control the sound and light alarm 1 and the speaker 7 at the same time. An alarm is issued. When the ship collides with the flexible net 10, the floating body 8 will buffer and slow down the ship and fix it in a certain horizontal area to prevent the ship from further colliding with the pier of the wading bridge and avoid causing damage to the wading bridge. At the same time, the control chip 5 integrates the video data from the camera 4 and the geographic location data obtained by the GPS module 2 and transmits them to the terminal device.
