As shown in fig. 1 to 9, an embodiment of a navigation forbidden warning facility for a ship navigation water area comprises two fixing parts 100, a rope 200 for connecting the two fixing parts, and a plurality of floating drums 300 which are fixedly connected in series along the trend of the rope 200, wherein part of the length of the rope 200 is reserved, and the rope 200 adopts a steel core steel wire rope. The floating drums 300 are connected in series with the rope 200 so that the floating drums 300 are arranged side by side along the two sides of the river course, and each floating drum 300 floats on the water surface along the direction perpendicular to the water surface. The two fixing parts 100 are respectively fixed on two sides of the river channel; at least one floating drum 300 is provided with a warning device 310, the material of the floating drum 300 is marine grade steel plates, the inside and the outside of the floating drum 300 are subjected to corrosion prevention treatment, the floating drum 300 is arranged in a cylindrical upright structure, and the ropes 200 penetrate through the cylindrical upright structure along the radial direction. The warning device 310 comprises a warning sign and a solar navigation light, and the navigation light emits light for warning at night, so that the passing ship can be reminded of keeping a certain safe distance from the protection facility for sailing. The bottom of each floating drum 300 is connected with a balancing weight 400 through an anchor chain 500, and the balancing weights 400 are placed on the riverbed to ensure that the distance between the rope 200 and the water surface is within a preset range in different water level states, so as to block the ship 600. Further, the lengths of the anchor chains 500 are different from each other to ensure that at least one weight 400 is submerged in the water under different water levels, thereby helping to limit the position of the float 300.

When in use, the water level II 1 is taken as a normal water level, and the floating drum 300 can stably float on the water surface of the water level II 1 under the action of the gravity of the anchor chain 500 and the balancing weight 400. At least one anchor chain 500 is fully unfolded under the water bottom under the action of buoyancy stretching of the floating drums 300, the rest anchor chains 500 connected with each floating drum 300 are not fully unfolded under the buoyancy stretching of the floating drums 300, and part of the length of the anchor chains 500 is reserved, so that the height distance between the rope 200 and the water surface can be always kept within a preset range under different water level states by limiting the draft of the floating drums 300 within a preset draft interval. When the rope 200 blocks the ship, the friction force between the balancing weight 500 and the river bed can counteract the impact force transmitted by a part of ships, so that the stress of the rope is reduced, and the service life of the rope 200 is ensured.

When the river water level is lowered from the water level II 2 to the water level III 3, the float drum 300 can be lowered to the water level III 3 along with the water level II 2 and float on the water surface of the water level III 3. Due to the water level drop, the original at least one fully deployed anchor chain 500 becomes not fully deployed, so that the draft of the floating drum 300 is within the preset draft interval, thereby meeting the requirement that the distance between the rope 200 and the water surface is within the preset range, and avoiding the possibility that a ship, especially the small ship 600, passes directly under the rope due to the rope 200 being higher than the water surface.

When the river water level ii 2 rises to the water level i 1, the floating drum 300 also rises to the water level i 1 along with the water level ii 2, and at least one anchor chain 500 is not fully unfolded under the buoyancy action of the floating drum 300, so that the draft of the floating drum 300 is within a preset draft interval, further, the distance between the ropes 200 connected with each floating drum 300 and the water surface is ensured to be within a preset range, the ropes 200 are prevented from being lower than the water surface, and the possibility that the ship 600 directly passes over the ropes exists.

As shown in fig. 5 to 7, the fixing portion 100 includes a cap beam 110, three fixing piles 120 and a yoke 130, the fixing piles 120 are reinforced concrete cast-in-place piles, and the three fixing piles 120 are arranged in a triangle. One fixing pile 120 is disposed on the water facing side of the river bank, the remaining two fixing piles 120 are disposed side by side and parallel to the river bank, and the adjacent fixing piles 120 are connected through the yoke 130, so as to ensure the stability of the structure of the fixing portion 100. The hat beams 110 are arranged in a triangle shape, the hat beams 110 are correspondingly and fixedly arranged at the tops of the fixed piles 120, and the hat beams 110 are reinforced concrete hat beams. The fixing portion 100 can more firmly engage with the rope 200 to intercept the ship when the ship enters the restricted area.

As shown in fig. 5 to 6, the cap beam 110 is provided with a pull ring 111, the pull ring 110 is made of round steel, and the pull ring 111 is connected with a rope 200 for intercepting a ship 600 driving into a forbidden area.

As shown in fig. 8 to 9, the weight 400 is a concrete precast block or a cast iron finished product, the top of the weight 400 is provided with an anchor hook 410, the anchor hook 410 is connected with an anchor chain 500, and the anchor chain 500 is made of cast iron. The bottom of the balancing weight 400 is pre-roughened to form a rough surface at the bottom of the balancing weight 400, so as to increase the friction between the balancing weight 400 and the river bed and further limit the position of the float drum 300.

In summary, the fixing parts are fixedly arranged on two sides of a river channel, the fixing parts on the two sides are connected through the ropes, the plurality of floating drums are connected in series on the ropes, the warning device is arranged on the floating drums to warn the ship, and the floating drums are connected with the balancing weights on the river bed to limit the positions of the floating drums.
