Description

Technical Field

[0001] The utility model relates to the technical field of flood control buoys, in particular to a flood control buoy for a water conservancy project. Background Art

[0002] In order to control the water level and carry out flood prevention work in a timely manner, it is necessary to use flood prevention buoys to assist in observing the water level.

[0003] A flood control buoy for a water conservancy project is disclosed in Chinese utility model CN218258602U. The flood control buoy for a water conservancy project is set to move up and down on the outside of a liquid level column according to the water depth conditions during the flood season, thereby displaying the water depth outside the liquid level column. When the water level rises, the flood control buoy moves upward under the action of buoyancy, so that the liquid level warning tooth column can move upward under the action of a coil spring, thereby raising the height of the warning light, thereby achieving the purpose of increasing the warning effect and effectively reducing the length of the device exposed on the water surface. However, the flood control buoy for a water conservancy project fixes the buoy assembly to the bottom of the water through a long rod, so that the detectable depth is affected by the height of the liquid level column, and therefore it is impossible to monitor excessively deep water levels, such as reservoir water level monitoring. Therefore, an excessively high liquid level column is difficult to stably fix to the bottom of the water and is prone to tipping over. Utility Model Content

[0004] The purpose of the present invention is to solve at least one of the above technical deficiencies.

[0005] Therefore, one purpose of the utility model is to provide a flood control buoy for water conservancy projects to solve the problems mentioned in the background technology and overcome the shortcomings of the prior art.

[0006] In order to achieve the above-mentioned purpose, an embodiment of one aspect of the utility model provides a flood control buoy for a water conservancy project, comprising a floating platform, a guide sleeve fixedly connected at the center of the floating platform, a fixed frame fixedly connected at the top of the guide sleeve, a rotating shaft rotatably connected at the center of the inner wall of the fixed frame, a winding winch fixedly connected at the position corresponding to the rotating shaft and the guide sleeve, a traction rope is wound and fixedly connected to the inner wall of the winding winch, the traction rope passes through the guide sleeve to the bottom of the floating platform, an anchor assembly is fixedly connected to the bottom end of the traction rope, one end of the rotating shaft passes through the middle of one side of the outer wall of the fixed frame, a worm is fixedly connected to the side of the rotating shaft away from the winding winch, a connecting ear is fixedly connected to the side of the top of the fixed frame close to the worm, a rotating shaft is rotatably connected to the middle of the connecting ear, a transmission worm wheel is fixedly connected to the middle of the rotating shaft, the transmission worm wheel is meshed with the worm, a mechanical counter and a rotation number sensor are fixedly connected to both sides of the fixed frame, and both ends of the rotating shaft are fixedly connected to the rotation input ends of the mechanical counter and the rotation number sensor respectively.

[0007] Preferably, any of the above schemes is that an alarm is fixedly connected to one side of the top of the fixed frame, and the signal output end of the rotation number sensor is electrically connected to the opening and closing signal input end of the alarm.

[0008] The technical effect achieved by adopting the above scheme is that the number of rotations of the rotating shaft will be detected by the rotation number sensor, and when the threshold is reached, the alarm will be turned on to sound an alarm.

[0009] Preferably, any of the above schemes has a coil spring fixing sleeve fixedly connected to a position corresponding to one end of the rotating shaft on a side surface of the outer wall of the floating platform, a coil spring fixedly connected to an inner wall of the coil spring fixing sleeve, and an inner side of the coil spring fixedly connected to an outer wall of one end of the rotating shaft.

[0010] The technical effect achieved by adopting the above scheme is: the winding force of the coil spring can improve the tensioning effect of the traction rope, so that when the floating platform falls, the rotating shaft and the winding winch are automatically driven to rotate and wind, while preventing the floating platform from drifting.

[0011] Preferably, in any of the above schemes, the anchoring assembly comprises a connecting ear plate, and anchoring screws penetrate the centers of both sides of the connecting ear plate.

[0012] The technical effect achieved by adopting the above scheme is that the connecting ear plate is fixed to the bottom of the water by the anchoring screw, so that the stability can be improved and it is not easy to fall off.

[0013] Preferably, in any of the above schemes, the anchoring assembly is an anchor structure.

[0014] The technical effect achieved by adopting the above scheme is that the anchor structure is easy to install, and only the anchoring component needs to be sunk to the bottom of the water and hooked.

[0015] Compared with the prior art, the advantages and beneficial effects of the utility model are:

[0016] The flood control buoy of this water conservancy project fixes the anchoring component to the bottom of the water so that the floating platform floats on the water surface. When the water level rises, the towing rope will pull the winding winch to unwind, causing the rotating shaft to rotate and drive the worm to rotate, thereby driving the transmission worm gear to rotate, causing the rotating shaft to rotate, driving the mechanical counter to rotate and count to obtain the current water level. At the same time, the number of rotations of the rotating shaft will be known by the rotation number sensor, and the alarm will be activated when the threshold is reached. A deeper measurement range can be obtained by fixing the monitoring with the towing rope. At the same time, the buoy itself is small in size and not easy to overturn. Moreover, its position is relatively stable and not easy to drift, thereby improving practicality. BRIEF DESCRIPTION OF THE DRAWINGS
