Description

Technical Field

[0001] The utility model relates to the technical field of float - type water - level warning devices, in particular to a real - time warning system for basin monitoring. Background Art

[0002] The water level refers to the elevation of the free water surface relative to a certain reference plane, and the distance from the water surface to the river bottom is called the water depth.

[0003] In the prior art, water - level detection is an important detection information for flood warning. Most of the existing water - level detection devices are set in the riverbed. When the water level rises, the flow velocity of the river water becomes faster, and it is easy for the river water to mix with foreign objects such as sand, stones, and wooden blocks. When these objects flow through the water - level detection device, it is easy to generate a large thrust on the device, resulting in problems such as device deformation or even tipping.

[0004] Moreover, these foreign objects are also easy to block the water inlet of the water - level detection device. At this time, the water flow cannot enter the inside of the water - level detection device, thereby causing the water - level detection device to be unable to accurately detect the water level and give an early warning. Content of the Utility Model

[0005] According to the deficiencies of the prior art, the purpose of the utility model is to provide a real - time warning system for basin monitoring, so as to solve the technical problems mentioned in the above - mentioned background art.

[0006] The above - mentioned technical purpose of the utility model is achieved through the following technical solutions:

[0007] A real - time warning system for basin monitoring includes a protection cylinder. At the inner bottom end of the protection cylinder, a float warning component is arranged. At the bottom end of the outer peripheral wall of the protection cylinder, a flange pipe is arranged, and at the top end of the flange pipe, a water inlet component is arranged.

[0008] The float warning component includes an installation pipe which is fixedly arranged inside the protection cylinder. An extension rod is slidably arranged inside the installation pipe. A float ball is arranged at the top end of the extension rod, and a support frame is arranged at the bottom end of the extension rod. A transmission gear plate is arranged inside the support frame. A connecting pipe is arranged inside the pipe wall of the installation pipe. A connecting shaft is rotatably arranged inside the connecting pipe. A linkage gear is arranged at the end of the connecting shaft, and the linkage gear meshes with the transmission gear plate. An alarm is arranged inside the extension rod.

[0009] An angle detector and a speed detector are arranged inside the connecting pipe. Angle deflection probes and speed detection probes are respectively arranged at positions on the outer peripheral wall of the connecting shaft corresponding to the angle detector and the speed detector.

[0010] Furthermore, a sliding pipe is arranged at the bottom end of the float ball. The sliding pipe is sleeved on the top end of the extension rod and is slidably connected to the extension rod.

[0011] Further, a hose is arranged at the inner center of the floating ball, and a through hole for passing through the hose is arranged inside the extension rod. A photovoltaic panel is arranged at the top of the floating ball, and a storage battery connected to the photovoltaic panel through a wire is arranged inside the extension rod.

[0012] Further, the water inlet assembly includes a rotating ring rotatably arranged at the top of the flange pipe. A plurality of uniformly distributed water guide vanes are arranged at the top of the rotating ring. An inlet gap is arranged between adjacent water guide vanes. A stabilizing ring is commonly arranged at the top of the water guide vanes. A shielding cover is arranged on the outer peripheral wall of the top of the flange pipe, and a water inlet groove is arranged on the side wall of the shielding cover.

[0013] Further, the inner bottom surface of the protection cylinder is inclined, and a sedimentation cylinder is arranged at the bottom side. A sand retaining net is arranged inside the sedimentation cylinder.

[0014] In summary, the present utility model includes at least one of the following beneficial technical effects:

[0015] 1. For this real-time warning system for watershed monitoring, affected by buoyancy, the floating ball moves upward, pulling the extension rod upward. The transmission toothed plate is cooperated to drag the linkage gear to rotate. After the linkage gear rotates, it drives the connecting shaft to rotate. The sensor inside the connecting pipe detects the rotation speed and the number of rotation turns of the connecting shaft. The rising height of the water level is judged by the number of rotation turns, and at the same time, the rising speed of the water level is judged by the rotation speed. When either the rising height of the water level or the rising speed of the water level is greater than the set threshold value, the alarm generates an alarm.

[0016] 2. For this real-time warning system for watershed monitoring, the water guide vanes are shielded by the shielding cover. At this time, the river water can only push the water guide vanes on one side of the axis of the rotating ring, causing the rotating ring to rotate. When a foreign object contacts the water guide vanes, the foreign object can be unloaded through the rotation of the water guide vanes, avoiding the impact of foreign objects in the river on the water guide vanes, so as to protect the equipment from damage or blockage.

By opening pre-buried holes in the riverbank for installing the protection cylinder 1, and extending the water inlet assembly 4 into the upper part of the riverbed through the flange pipe 3. At this time, the inside of the protection cylinder 1 is connected to the riverbed through the flange pipe 3. According to the principle of the communicating vessel, the water level in the riverbed is flush with the water level inside the protection cylinder 1 at this time. When the water level in the riverbed rises, the water level inside the protection cylinder 1 will also rise accordingly;

[0028] The water inlet assembly 4 filters the water entering the inside of the flange pipe 3 to prevent foreign objects from entering the inside of the flange pipe 3 and prevent the flange pipe 3 from being blocked;

[0029] When the water level inside the protection cylinder 1 rises, the float 23 moves upward under the influence of buoyancy and pulls the extension rod 22 upward. During the upward movement of the extension rod 22, it pulls the transmission gear plate 25 upward and drags the linkage gear 28 to rotate. After the linkage gear 28 rotates, it drives the connecting shaft 27 to rotate. The sensor inside the connecting pipe 26 detects the rotation speed and the number of rotation turns of the connecting shaft 27. The rising height of the water level is judged by the number of rotation turns, and at the same time, the rising speed of the water level is judged by the rotation speed.
