Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of reservoir dam monitoring, in particular to a reservoir dam monitoring and early warning device. BACKGROUND

[0002] As a key facility of water conservancy projects, reservoir dams play an irreplaceable role in flood control, irrigation, water supply, power generation and other fields. However, dam safety faces many complex challenges, and water level change is one of the most critical and dynamic factors. Precise and real-time monitoring and early warning of reservoir dam water level is a core task to ensure the safe and stable operation of the dam and fully play its comprehensive benefits. Under the background of global climate change, extreme rainfall events are becoming more frequent, and floods caused by heavy rainfall often cause the water level of the reservoir to rise sharply in a short time. The environment of the reservoir dam is complex and diverse, and the water flow characteristics differ significantly in different regions. The water level in the dam changes periodically, and the water flow speed is large and small. The water flow speed near the spillway during the spillway period can reach several meters per second, and the impact force is huge. The dam bottom drainage outlet is subjected to high pressure water flow scouring for a long time. In such an environment, the installation stability of the traditional water level monitoring and early warning device is severely challenged. The equipment is easily displaced, tilted or even damaged by water flow impact, causing the monitoring position to deviate from the preset point, and the collected water level data cannot truly reflect the actual operation status of the dam, seriously affecting the accuracy and timeliness of the early warning. Therefore, we need a reservoir dam monitoring and early warning device.

[0003] The currently used reservoir dam monitoring and early warning device is affected by water flow and deviates from the preset water level monitoring point, resulting in collected water level data that cannot reflect the true water level in front of the dam. In the narrow installation scene of the dam top and dam shoulder, the parts cannot be installed in a guided manner, and the installation efficiency is low. Because the device cannot quickly adjust the monitoring point for different positions, it is easy to be overturned by the water flow impact only relying on the buoyancy of the float ball to maintain the posture. SUMMARY

[0004] The purpose of the present application is to provide a reservoir dam monitoring and early warning device to solve the problems raised in the background art.

[0005] To achieve the above purpose, the present application provides the following technical solutions:

[0007] Preferably, the connecting rod is engaged with the cable, and the connecting rod is arranged in an annular array on the outer wall of the base.

[0008] Preferably, the guide plates are arranged in an annular array on the outer wall of the connecting sleeve, and the inner wall of the connecting sleeve is threadedly arranged.

[0009] Preferably, the counterweight is engaged with the base, and the inner wall of the counterweight is designed as a slotted type.

[0010] Preferably, the outer wall of the second magnetic sleeve is tightly attached to the inner wall of the protection frame, and the outer wall of the second magnetic sleeve has a smaller diameter than the inner wall of the protection frame.

[0011] Preferably, the lower floating ball sleeve is threadedly connected with the upper floating ball sleeve, and the outer wall of the lower floating ball sleeve is threadedly arranged.

[0012] Preferably, the adjusting sleeve is movably connected with the guide rod, and the inner wall of the adjusting sleeve is designed as a perforated type.

[0013] Preferably, the adjusting sleeve is movably connected with the eccentric block, and the eccentric block is symmetrically arranged about the central axis of the adjusting sleeve.

[0014] Compared with the prior art, the utility model has the beneficial effects that:

[0015] The base adopts a circular metal shell, the edges of which are connected to connecting rods in a ring array uniformly distributed in the circumferential direction, one end of each connecting rod is connected to the side wall of the base through an internal threaded hole, and the other end is provided with a ring-shaped hanging hole for connecting a steel cable. The ring array design makes the pulling force of the connecting rods uniformly distributed on the base, avoiding overload fracture of a single connecting rod, and forms a stable triangular support foundation, providing structural support for subsequent anti-deviation fixation. The hanging holes of each connecting rod are connected to the anchor rods pre-set in the dam body through a steel cable made of galvanized steel wire. The anchor rod is a metal anchoring device implanted in the concrete inside the dam body. When the device is impacted by water flow, the lateral thrust generated by the water flow on the base is transmitted to the steel cable through the connecting rod, and then the pulling force is dispersed to the dam body structure by the anchor rod, forming a force transmission chain to limit the lateral deviation of the base. At the same time, the ring distribution of multiple steel cables can offset the rotational torque generated by the water flow, preventing the base from overturning in a single direction and ensuring that the device is always fixed at the preset monitoring position, avoiding misplacement of the water level monitoring point due to deviation. A circular counterweight cavity is reserved inside the base, and a detachable counterweight block is placed in the cavity. The counterweight block can be replaced with different materials according to the water flow speed difference. Cast iron is used in low flow speed areas, and lead alloy is used in medium and high flow speed areas. By increasing the weight of the lower part of the base, the overall center of gravity of the device is lowered, reducing the risk of tipping caused by water impact. The outer wall of the counterweight block and the inner wall of the counterweight cavity are in transition fit to avoid additional torque caused by the counterweight block shaking in the cavity when impacted by water flow. At the same time, the counterweight block is fixed by the top connecting sleeve and the base to prevent it from falling off. At the same time, the bottom of the base is fixed by a positioning rod structure, which, together with the downward pressure of the counterweight block, makes the device fit the dam surface more tightly and improves the overall anti-deviation ability. The top of the base is fixed to the connecting sleeve, and multiple guide plates are welded to the outside of the upper end of the connecting sleeve in the circumferential direction. The guide plates are fan-shaped metal plates that are inclined inward along the radial direction of the connecting sleeve, forming a tapered guide structure that is narrow at the top and wide at the bottom. The ring-shaped opening at the bottom of the protection frame can quickly slide along the inclined surface of the guide plate without the need for precise manual alignment, guiding the protection frame to align coaxially with the connecting sleeve. This installation alignment shortens the installation time and greatly improves the installation efficiency. The outer wall of the connecting sleeve is bonded to a first magnetic sleeve in the middle. The first magnetic sleeve is a ring-shaped permanent magnet. A second magnetic sleeve, which is a ring-shaped permanent magnet with opposite polarity to the first magnetic sleeve, is bonded to the inner wall of the protection frame. When the protection frame slides along the guide plate to the designated position, the first and second magnetic sleeves automatically adhere due to the attraction of opposite poles, generating a magnetic attraction force that quickly fixes the protection frame outside the connecting sleeve without the need for bolt fastening. This allows for quick disassembly and assembly of the protection frame, solving the problem of complicated disassembly and assembly of traditional bolt fixation. A cylindrical guide rod is welded to the top of the connecting sleeve, and an axial anti-slip pattern is processed on the surface of the guide rod. An adjustment sleeve, which is a metal sleeve with an inner diameter that matches the guide rod, can slide up and down along the guide rod, making it easy for manual quick height adjustment. A circular mounting hole is processed on the side wall of the adjustment sleeve for fixing the floating ball trigger type water level alarm, allowing the floating ball trigger type water level alarm to rise and fall synchronously with the adjustment sleeve to meet the height requirements of different water level monitoring points. An eccentric block is vertically installed on the side wall of the adjustment sleeve. The eccentric block is a fan-shaped metal block that is hinged to the adjustment sleeve through a shaft in the middle.The rotatable shaft can rotate, the rubber pad is bonded to the side of the eccentric block which faces the guide rod, and the outer side is provided with a manual pressing frame, when the adjusting sleeve slides to the target height, the pressing frame of the eccentric block is manually rotated, the eccentric block rotates around the rotating shaft, the pressure generated by the eccentric structure pushes the rubber pad to tightly contact the anti-skid lines on the surface of the guide rod, self-locking fixation is formed, the fixing force can resist the sliding of the adjusting sleeve caused by water flow impact, if the height needs to be adjusted again, the eccentric block is reversely rotated to release the fixation, the height positioning requirement of water level monitoring is met.
