Description

Technical Field

[0001] The invention relates to the technical field of bridge pier safety protection, and in particular to a warning device with a retractable cable. Background Art

[0002] With the construction of the hub, the waterway grade has been improved, and the change in the water level in the reservoir area has led to changes in the navigation environment in the bridge area. Traditional fixed pier warning devices are easily damaged by water level changes and harsh environmental conditions, have high maintenance costs, and rely on external power supplies. Once the power is off, the effect is poor.

[0003] Traditional fixed pier warning devices often require underwater piling to fix their structures. They provide navigation information and warnings to ships mainly by providing lights and reflective strips. However, their fixed structure and reliance on external power supplies may make them vulnerable to damage due to water level changes and harsh environmental conditions. They have high maintenance costs and are not effective in power outages. In addition, the warning devices are fixed and cannot move with the water level.

[0004] The patent with publication number CN114321808A discloses a cliff beacon suitable for the Three Gorges Reservoir area, comprising a guide rail, a beacon light and a float, wherein the guide rail is extended along the height direction of the cliff, the float moves along the guide rail as the water level of the river rises and falls, and the beacon light is mounted on the float; a mounting groove is provided on the float, the beacon light comprises a lamp holder, a lamp body and a lampshade, the lamp holder is arranged in the mounting groove, a plurality of elastic members are evenly arranged circumferentially between the lamp holder and the inner side wall of the mounting groove, the lamp body is mounted on the lamp holder, a shock absorbing structure is provided between the lamp body and the lamp holder, a mounting cavity is provided in the lamp holder, a battery is provided in the mounting cavity, a solar panel is provided on the lamp holder, the solar panel is electrically connected to the battery, and the battery supplies power to the lamp body.

[0005] The above-mentioned cliff beacons applicable to the Three Gorges Reservoir area only exist in the Three Gorges section of the Yangtze River in China. Because their cliff beacons are located on steep cliffs, they cannot be deployed at sea or in plain rivers. (The maintenance of the "cliff beacons" becomes difficult, and a steel ladder is required as a bridge to facilitate maintenance workers to climb to a high place. However, the simple steel ladder is narrow and steep, and maintenance workers carrying maintenance tools must take off their life jackets and climb to the steep working platform to work, which greatly increases the difficulty and risk of maintenance.) And the slide rails are easily contaminated and blocked.

[0006] The existing bridge pier warning devices are difficult to construct and maintain, and are severely restricted by geographical, traffic and natural conditions (only applicable to cliffs in mountainous rivers). They are also expensive, and the device shakes greatly under the influence of external forces such as wind, waves and currents. They are difficult to construct on cliffs, have a long construction window period, and cannot be assembled quickly.

[0007] In order to solve these problems, the present invention proposes a floating platform pontoon integrated bridge pier warning device. Summary of the invention

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] like Figures 1 to 6 As shown, the present embodiment provides a warning device with a retractable cable, comprising a suspended platform body 1, a water level detection mechanism, an anchor cable 6 retracting and releasing mechanism and a power generation mechanism; the water level detection mechanism is arranged on the top of the suspended platform body 1; the anchor cable 6 retracting and releasing mechanism is arranged inside the suspended platform body 1, and the anchor 7 arranged at the free end of the anchor cable 6 of the anchor cable 6 retracting and releasing mechanism extends out of the suspended platform body 1; the water level detection mechanism and the anchor cable 6 retracting and releasing mechanism are electrically connected to control the height of the suspended platform body 1 in the water; the power generation mechanism is used to provide power to the water level detection mechanism and the anchor cable 6 retracting and releasing mechanism.

In a more specific embodiment, the sliding column is a sliding double column 4; the sliding double column 4 includes two parallel cylinders; the upper sensor 3 and the lower sensor 5 are arranged between the two parallel cylinders. The sliding double column 4 can prevent the buoy 2 from rotating and improve the structural strength of the sliding column.

[0038] A navigation light and a warning sign are arranged on the top of the buoy 2 to provide high-efficiency visibility warning.

[0039] When the water level changes greatly, when the water level rises, the buoy 2 slides upward along the sliding double column 4. When the buoy 2 floats to the upper end sensor 3, the control system determines that the water level is high at this time, and the control system sends a signal to the drive motor 15 to release the anchor cable 6, so that the suspended platform body 1 rises to an appropriate position; when the water level drops, the buoy 2 slides downward along the sliding double column 4. When the buoy 2 slides down to the lower end sensor 5, the control system determines that the water level is low at this time, and the control system sends a signal to the drive motor 15 to retract the anchor cable 6, so that the suspended platform body 1 drops to an appropriate position.

[0040] Four control rooms 17 are arranged in the main body 1 of the suspended platform, and each control room 17 is provided with a mechanism for retracting and releasing the anchor cable 6. The specific number of the control rooms 17 can be set according to the number of the mechanisms for retracting and releasing the anchor cable 6.

[0045] A cross-shaped longitudinal rib plate 18 is arranged in the horizontal direction inside the main body 1 of the suspended platform, a ring plate 21 is arranged in the middle of the longitudinal rib plate 18, and a gravity pendulum 25 is arranged inside the ring plate 21. Under the action of external forces such as wind, waves and currents, the swing of the gravity pendulum 25 can consume part of the energy, thereby reducing the overall shaking amplitude of the navigation mark, ensuring the stability of the navigation mark position, and providing accurate navigation information for ships.

[0046] The warning device with a retractable cable in the present invention relies on photovoltaic power generation above the sliding double columns 4. The generated electricity is stored in the lithium iron phosphate battery in the control room 17 and is used for consumption of navigation lights, sensors, control systems, drive motors 15, etc., thereby achieving autonomous power supply.
