Description

Conical buoy for navigation channel in inland mountain area Technical Field The application relates to the field of water transport engineering, in particular to a cone-shaped buoy for a channel in a mountain area of a inland river. Background In a inland waterway, a conventional buoy is connected to a weight by a fixed length anchor chain and anchored to the river bottom to indicate the waterway and navigation hazards. However, in mountain channels, the water level may rise or fall sharply due to the influence of factors such as rainy seasons and typhoons, and the height difference may be several meters to several tens of meters. The traditional buoy cannot adapt to the severe water level change due to the fixed length of the anchor chain, namely, the water level is too high, if the anchor chain is too short, the buoy is wholly immersed in water, the buoy loses the identification function, meanwhile, due to the buoyancy of the buoy, the buoy can possibly pull a heavy object away from the river bottom through the anchor chain and be flushed away by water flow, if the anchor chain is long, when the water level is too low, the long anchor chain is insufficient to bind the buoy, the buoy drifts under the water flow, the functions of accurately marking a channel and calibrating a water area are lost, and the risk of ship collision is increased. Disclosure of utility model In order to solve the problems, the application provides a cone-shaped buoy for a mountain area channel of a inland river, which automatically adjusts the length of a rope anchor along with the water level, and the cone-shaped buoy comprises the following specific scheme: a inland mountain channel cone buoy, comprising: A float housing; telescoping device, and An anchor block; the telescopic device is arranged and fixed on the inner wall of the buoy shell, The telescopic device comprises a shell, a rotor, a rotating shaft and a rotor spring, wherein the rotor is arranged in the shell and is in a disc-shaped structure rotating around the rotating shaft; one end of the fiber rope is coiled and fixed on the rotor; through holes are respectively formed in the buoy shell and the shell of the telescopic device, and one unfixed end of the fiber rope sequentially penetrates through the through holes and is connected with an anchor chain; one end of the anchor chain, which is not connected with the fiber rope, is fixed on the anchor block; An annular counterweight is disposed within the float housing. In one specific embodiment of the application, the buoy shell is formed by combining an upper half part and a lower half part, wherein the upper half part is a hollow cone with an open bottom, the lower half part is of a structure with a wide upper part and a narrow lower part and a convex middle part, and the upper half part and the lower half part are fixed through bolts and nuts. In one embodiment of the application, the telescoping device is secured to the inner wall of the float housing by a bolt and nut. In one embodiment of the application, a rubber seal is provided on the float housing through-hole and/or outside the housing through-hole of the telescoping device. In one embodiment of the present application, the fiber rope is made of one selected from polyethylene, aramid and steel wire rope. In one embodiment of the present application, the material of the buoy housing is selected from one of High Density Polyethylene (HDPE), polypropylene (PP), ABS, nylon (PA), glass Fiber Reinforced Plastic (FRP), carbon fiber composite, polyurethane, stainless steel, and aluminum alloy. In one embodiment of the present application, the height (H) of the upper half is 0.6 to 1.5m, and the bottom diameter (D) is 0.7 to 1.8m.

In one embodiment of the application, the diameter of the anchor chain is 2.5-5 mm. The beneficial effects of the application are as follows: The conical buoy for the mountain channel of the inland river is internally provided with the rotor, and the fiber ropes coiled on the rotor can automatically stretch along with the water level so as to adapt to the characteristics of the mountain channel of water level storm drop, rapid change of the water level and the like, thereby ensuring that the buoy does not have the conditions of anchor block frog jump, buoy body inundation or drifting and the like, and the conical buoy has wide bottom, low gravity center and stronger stability when being impacted by stormy waves due to the bottom counterweight. Meanwhile, the buoy is simple in structure, the fiber ropes can achieve the effect of adapting to water level change without being matched with other simple mechanical structures, abrasion of the fiber ropes is avoided to a certain extent, the telescopic device is arranged in the buoy and provided with a plurality
