Description

Technical Field

[0001] This utility model relates to the field of reservoir early warning technology, and in particular to a reservoir basin flood forecasting device. Background Technology

[0002] Reservoir flood forecasting is a crucial link in river basin flood control and disaster reduction, playing a decisive role in ensuring the safety of people and property downstream and scientifically managing reservoir capacity. Accurate and timely reservoir water level monitoring is the foundation of flood forecasting. Traditional reservoir water level monitoring devices, such as water level gauges, float-type or pressure-type water level gauges, are usually installed on the reservoir bank, within the dam structure, or in fixed monitoring stations. However, for monitoring points that require flood forecasting at specific locations within the reservoir area (such as the reservoir tail, reservoir bifurcation, near the inflow river mouth, or specific hydrological sections), it is often necessary to deploy the monitoring equipment directly on the reservoir bed.

[0003] This underwater installation method faces unique challenges: reservoir bed sediments are typically soft (such as silt and gravel) and subject to long-term erosion by water flow. Existing installation methods for underwater monitoring equipment, such as simply placing heavy objects or using small concrete pier foundations, rely primarily on the equipment's own weight and the friction between the foundation structure and the bed surface to resist overturning and displacement. This method has significant drawbacks in soft bed environments: Insufficient anti-overturning ability: Relying solely on its own weight and surface friction, the device is prone to tilting or even tipping over when subjected to strong water flow impact, wave action, or lateral forces on the main structure of the equipment (such as long columns), leading to inaccurate water level sensors, abnormal posture, or damage to communication lines.

[0004] Limited pull-out resistance: The surface grip provided by the soft substrate is weak, especially under continuous water flow, the device is prone to slow slippage or even being pulled up, causing the monitoring point to drift. Therefore, a reservoir basin flood forecasting device is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0006] Therefore, one objective of this utility model is to propose a flood forecasting device for reservoir basins to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0007] To achieve the above objectives, one embodiment of the present invention provides a reservoir basin flood forecasting device, including a base, a gravity block, a cage, and a panel. The gravity block is fixedly connected to the bottom of the base, the cage is fixedly connected to the bottom of the gravity block, the panel is fixedly connected to the front of the cage, and the cage is filled with stones. The base is fixedly connected to two joints, and a rotating column is movably connected to the joint. An internal hexagon head is fixedly connected to the top of the rotating column, and a spiral blade is fixedly connected to the outer surface of the rotating column. A chassis is fixedly connected to the top of the base, a column is fixedly connected to the middle of the top surface of the chassis, a water level sensor is fixedly connected to the side of the column, and the detection end of the water level sensor is attached to the column. A top base is fixedly connected to the top of the column, a main unit is fixedly connected to the top of the top base, and an alarm light is fixedly connected to the top of the top base. The main unit is connected to an external device via a physical cable. The input end of the main unit is connected to a water level sensor, and the output end of the main unit is connected to the alarm light.

[0008] Preferably, in any of the above solutions, the base is a single piece of steel plate, and a reinforcing mesh is fixedly connected to the bottom of the base, with the reinforcing mesh embedded in a gravity block to achieve the connection between the base and the gravity block.

[0009] The above technical solution is adopted: This device is specifically used for the forecasting of reservoir floods. Specifically, it monitors the reservoir water level using a water level sensor and uploads the data to the host computer in real time. When the water level exceeds the warning value, the host computer activates the alarm light and flashes it to warn the user. At the same time, the host computer sends data to the host computer via cable.

[0010] Preferably, in any of the above schemes, the gravity block is a concrete block, and the top of the cage is pre-embedded in the gravity block.

[0011] Device Structure: Bottom Pull-Out System: Base: A single piece of steel plate structure with a radial reinforcing mesh welded to the bottom. Gravity Block: C30 concrete is poured under the base, with the reinforcing mesh embedded in the concrete to form a whole. Cage: The top is pre-embedded in the gravity block, and the bottom extends to the reservoir bed. A welded steel mesh cage is used, filled with stones with a particle size of 10-20cm.

[0012] Connector: Symmetrically welded to both sides of the base, connecting to a rotatable rotating column.

[0013] Rotating column and spiral blade: The rotating column has an internal hexagonal head at the top, and a spiral blade with a 15cm pitch is welded to the outer surface. Monitoring main structure: Chassis: Flange connected to the upper surface of the base. Column: Vertically fixed to the center of the chassis, made of 304 stainless steel pipe. Water level sensor: Piezoresistive sensor, longitudinally attached to the outer wall of the column, with the detection end 1m above the base. Top mount: Flange fixed to the top of the column. Main unit: Waterproof control box (IP68), with built-in 4G module and data processing unit. Alarm light: Red LED strobe light.

[0014] The above technical solution involves a core structure consisting of a base, a gravity block, a cage, a connector, an internal hexagonal head, and a spiral blade. Since the device is installed in the reservoir bed, a gravity block is fixedly connected to the bottom of the base to improve its stability. This block utilizes its own weight to resist overturning. After the reservoir bed is excavated, the cage is buried and filled with stones to integrate with the bed base, increasing pull-out resistance. Simultaneously, during construction, the internal hexagonal head is rotated, causing the rotating column to rotate and the spiral blade to screw into the reservoir bed base, further enhancing the pull-out resistance of the device's foundation. This device enables more stable installation in soft reservoir beds.

[0015] Preferably, in any of the above embodiments, the cage is welded to the panel, and the cage, gravity block, and spiral blade all enter the bottom of the reservoir.

[0016] Preferably, in any of the above solutions, the joint is welded to the base, and the chassis is connected to the base via a flange.

[0017] Preferably, in any of the above solutions, the column and the top base are connected by a number of screws, and the main unit is powered by mains electricity.

[0018] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: This reservoir flood forecasting device, through the coordinated arrangement of a base, gravity block, cage, connector, internal hexagonal head, and spiral blade, is installed in the reservoir bed. To improve its installation stability, a gravity block is fixedly connected to the bottom of the base, using its own weight to prevent overturning. After the reservoir bed is excavated, the cage is buried and filled with stones to bond with the bed base, increasing pull-out resistance. Simultaneously, during construction, the internal hexagonal head is rotated, the rotating column rotates, and the spiral blade is screwed into the reservoir bed base, further improving the pull-out resistance of the device's foundation. This device can achieve more stable installation in soft reservoir beds.

[0025] Example 1: The base 1 is a single piece of steel plate.

[0026] Example 2: Device Structure: Bottom Pull-out System: Base 1: A single piece of steel plate structure with a radial reinforcing mesh welded to the bottom. Gravity Block 2: C30 concrete is poured below Base 1, with the reinforcing mesh embedded in the concrete to form a whole. Cage 3: The top is pre-embedded in Gravity Block 2, and the bottom extends to the reservoir bed. A steel mesh cage is welded to it, and it is filled with stones with a particle size of 10-20cm.

[0027] Connector 5: Symmetrically welded to both sides of base 1, connecting to rotatable rotating column 6.

[0028] Rotating column 6 and spiral blade 8: The top of the rotating column 6 is equipped with an internal hexagonal head 7, and a spiral blade 8 with a pitch of 15cm is welded to its outer surface. Monitoring main structure: Chassis 9: Flange connected to the upper surface of the base 1. Column 10: Vertically fixed to the center of the chassis 9, made of 304 stainless steel pipe.

[0029] The working principle of this utility model is as follows: Installation and securing stage: The cage 3 is buried in the predetermined position on the reservoir bed, and stones are filled to form an embedded solid. The internal hex head 7 is rotated with a torque wrench to drive the spiral blade 8 to be screwed into the bed at a 45° angle to a depth ≥1.5m. The concrete gravity block 2 provides initial pressure, the stone filling cage increases frictional resistance, and the spiral blade 8 forms mechanical anchorage. The three together constitute a superposition of pull-out resistance.

[0030] During the flood monitoring phase: Water level sensor 11 monitors the relative height of the water surface in real time, and the data is transmitted to host 13 via RS485.

[0031] The host 13 compares the preset warning water level (e.g., exceeding the flood limit water level by 0.5m) and triggers a dual-channel alarm: a) activates the alarm light 14 to flash as a warning; b) uploads the water level data to the water conservancy dispatch center via cable / 4G.

[0032] Flood resistance stability mechanism: anti-overturning: gravity block 2 (about 2 tons) lowers the center of gravity, and the base 1 area (2m×2m) provides resistance torque.

[0033] Pull-out resistance: The spiral blade 8's insertion depth generates soil gripping force, and the stones inside the cage 3 combine with the substrate to form frictional resistance.

[0034] Compared with the prior art, the present invention has the following advantages: This reservoir flood forecasting device is constructed using a combination of a base 1, a gravity block 2, a cage 3, a connector 5, an internal hexagonal head 7, and a spiral blade 8. Since the device is installed in the reservoir bed, a gravity block 2 is fixedly connected to the bottom of the base 1 to enhance its stability and prevent overturning. After the reservoir bed is excavated, the cage 3 is buried inside, filled with stones that integrate with the bed base to improve pull-out resistance. Simultaneously, during construction, the internal hexagonal head 7 rotates, causing the rotating column 6 to rotate and the spiral blade 8 to screw into the reservoir bed base, further enhancing the pull-out resistance of the device's foundation. This allows for more stable installation even in soft reservoir beds.
