Description
Technical Field
[0001] The present invention relates to the technical field of hydrological monitoring, and in particular to an intelligent hydrological monitoring device and a monitoring method. Background Art
[0002] In the field of hydrological monitoring, accurate and efficient monitoring is crucial for water resource management, flood prevention and disaster reduction, and ecological and environmental research. However, traditional hydrological monitoring devices have exposed many problems in practical applications. First, they have high energy consumption. The monitoring cameras of most monitoring devices run continuously, regardless of whether the water flow rate is abnormal or requires key monitoring. This leads to a large amount of power consumption, which severely limits the battery life and requires frequent replacement or charging, greatly increasing manpower and material costs. This problem is particularly prominent in remote and difficult-to-reach monitoring areas. On the other hand, with regard to water sample collection, traditional devices find it difficult to ensure the independence and accuracy of water samples at different time periods. The commonly used single sampling method cannot effectively distinguish changes in water composition at different time points, which hinders the analysis of dynamic changes in water quality over time. For example, when a river is intermittently polluted or water quality fluctuates due to factors such as seasons and tides, traditional sampling methods are prone to data deviations and cannot provide a reliable basis for subsequent water quality assessments and environmental decision-making. Therefore, it is of great practical significance to develop an intelligent hydrological monitoring device that can intelligently start monitoring equipment according to the water flow rate, reduce energy consumption, and realize independent sampling of water bodies at different time periods to improve monitoring accuracy. Summary of the Invention
[0003] The purpose of the present invention is to provide an intelligent hydrological monitoring device and monitoring method to solve the problems of high energy consumption and difficulty in ensuring the independence and accuracy of water samples at different time periods raised in the above background technology.
[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an intelligent hydrological monitoring device, comprising a mounting flange, a battery is fixedly mounted on the upper surface of the mounting flange, and a mounting rod is fixedly connected to the upper surface of the mounting flange, a monitoring camera is fixedly mounted on the upper side surface of the mounting rod, and a sliding mounting plate is mounted on the lower end of one side of the mounting rod, the lower end of the mounting plate is fixedly connected to a mounting box, and the lower end of the mounting box is fixedly mounted to a mounting frame by bolts, and the mounting plate and the lower end outer surface of the mounting frame are fixedly connected to a buoyancy plate, and the surface of the mounting frame is provided with a constant speed starting mechanism and an independent sampling mechanism, which can actively start the monitoring camera when the flow rate exceeds the limit by monitoring the flow rate of the water body, thereby reducing the overall energy consumption of the monitoring device and improving the endurance time, and ensuring the accuracy of sampling by independent sampling of the water body at different time periods; The constant speed starting mechanism includes: a constant speed motor, the constant speed motor is fixedly mounted on the outer surface of the lower end of the mounting frame, and the lower end of the output shaft of the constant speed motor is fixedly connected to a constant speed disk, a rotating impeller is mounted on the lower end of the constant speed disk, and a clearance groove is formed on the outer surface of the impeller, and a connecting groove is formed on the inner top surface of the clearance groove, a mounting plate is fixedly mounted on the lower surface of the constant speed disk, and a press switch is fixedly mounted on the outer surface of one side of the mounting plate, a mounting seat is fixedly mounted on the upper end surface of the impeller, and a rotating flap is mounted on the inner surface of the mounting seat; The independent sampling mechanism includes: a switching motor, which is fixedly mounted on the upper outer surface of the mounting frame, and the lower end of the output shaft of the switching motor is fixedly connected to a switching disk, and a clamping block is fixedly provided on the lower surface of the switching disk, and a closing column is fixedly provided on the lower end of the clamping block, a sampling box is provided below the switching disk, and a liquid inlet pipe is provided inside the upper end of the sampling box, and a connecting seat is fixedly provided on the outer surface of the middle section of the sampling box, and a connecting block is fixedly provided on the upper end surface of the sampling box, an electric push rod is fixedly installed inside the mounting frame, and an electromagnet is fixedly installed on one end of the electric push rod.
[0005] Preferably, the buoyancy disc is of a conical design with a small upper portion and a large lower portion, and the buoyancy disc is arranged on one side of the installation box.
[0006] By adopting the above technical solution, its special shape is used to generate greater buoyancy in water without causing debris to accumulate on the buoyancy disk, so that components such as the mounting plate, mounting box and mounting frame can maintain appropriate positions in the water body, facilitating subsequent monitoring and sampling operations of the water body.
[0007] Preferably, one end of the connecting groove passes through the outer surface of the impeller, and the connecting groove is arranged at an equal angle on the outer surface of the impeller, and the connecting groove and the give way groove are arranged in a one-to-one correspondence, and the connecting groove is T-shaped.
[0008] The above technical solution makes it easy for the sampling box to be inserted into the connecting groove through the connecting block and engage with the giveway groove during the rotation of the impeller, so that the impeller drives the sampling box into the water for sampling. The T-shaped design can also ensure the stability of the connection and prevent the sampling box from falling off during the sampling process.
[0009] Preferably, the push switch is arranged on the outer surface of the mounting plate facing the flap, and a spring is connected between the flap and the mounting seat. The mounting seat is C-shaped, and one end of the mounting seat is opened toward the mounting plate.
[0010] With the above technical solution, when the water flow rate is normal, the flap will not touch the push switch, and the monitoring camera will remain in a low-power standby or shutdown state. When the water flow rate exceeds the set threshold, the impeller speed will accelerate, driving the flap to touch the push switch, thereby triggering the push switch to start the monitoring camera, thereby realizing intelligent control of the monitoring camera's operation according to the water flow rate and reducing the overall energy consumption of the device.
[0011] Preferably, a T-shaped groove is provided on the upper end side surface of the clamping block, and the clamping block is mounted by engaging with the connecting block through the T-shaped groove.
[0012] By adopting the above technical solution, the switching disk can stably drive the sampling box to rotate synchronously when rotating, ensuring the position accuracy of the sampling box during the switching process, so as to facilitate subsequent sampling operations. At the same time, the T-shaped groove engagement method also makes it convenient to separate the sampling box and the switching disk when needed.

[0014] By adopting the above technical solution, when the sampling box rotates with the switching disk, the closing column can effectively close the liquid inlet pipe to prevent external water from entering the sampling box in advance, thereby ensuring the accuracy of sampling. The sampling box and the giveway groove have the same shape, which facilitates the engagement of the two and ensures that the impeller can smoothly drive the sampling box into the water for sampling.
[0015] Preferably, a T-shaped groove is provided on the outer surface of the connecting seat, and the connecting seat is mounted by engaging with the electromagnet through the T-shaped groove.
[0016] By adopting the above technical solution, when sampling is required, the electric push rod pushes the electromagnet, and the electromagnet can engage with the connecting seat through the T-shaped groove, push the sampling box out and engage with the impeller's give way slot for sampling. When recovering the sampling box, the electromagnet can also use the T-shaped groove to engage with the connecting seat to adsorb the sampling box, which is convenient for subsequent operations and realizes precise control and recovery of the sampling box.
[0017] A monitoring method for an intelligent hydrological monitoring device, the monitoring method comprising the following steps: S1: Intelligent start of the monitoring camera: The fixed-speed motor drives the fixed-speed disk to rotate at a constant speed, and the impeller rotates with the water flow. When the water flow rate is normal, the impeller speed is lower than the fixed-speed disk, the flap will not touch the push-button switch, and the monitoring camera is in low-power standby or off state. Once the water flow rate exceeds the set threshold, the impeller speed increases, driving the flap to touch the push-button switch under the support of the mounting base. The push-button switch is triggered, sending a signal to the monitoring camera to start the monitoring camera, thereby reducing the overall energy consumption of the device; S2: Sampling preparation: The switching motor starts, driving the switching disk to rotate. The card block on the lower surface of the switching disk engages with the connecting block on the upper end surface of the sampling box through the T-shaped groove, so that the sampling box rotates with the switching disk. During the rotation process, the sealing column cooperates with the liquid inlet pipe of the sampling box to ensure that the sampling box is in a closed state; S3: Water sample collection: When the switching disk rotates to a specific position, the electric push rod pushes the electromagnet, and the electromagnet pushes the sampling box out by engaging with the connecting seat, so that the sampling box is inserted into the connecting slot through the connecting block and engages with the impeller's give way slot. At this time, the rotation of the impeller can drive the sampling box into the water for sampling.
[0018] S4: Sampling box recovery: After the sampling is completed, the electric push rod pushes the electromagnet to extend, and the electromagnet starts to generate magnetism. When the impeller drives the sampling box to rotate to the electromagnet, the electromagnet slides into the T-shaped groove of the connecting seat and adsorbs the connecting seat through magnetism, causing the impeller to stop rotating. At this time, the electric push rod drives the electromagnet to retract, so that the sampling box is disengaged from the give way slot, and the impeller resumes rotation, and the sampling box is driven through the connecting block to engage with the card block. At this time, the switching motor drives the switching disk to rotate and the electromagnet is powered off, so that the electromagnet is disengaged from the connecting seat, realizing the recovery of the sampling box. Compared with the prior art, the beneficial effects of the present invention are: the intelligent hydrological monitoring device: 1. Intelligent control of the monitoring camera's operation is achieved through a constant-speed starting mechanism. The constant-speed motor drives the constant-speed disk to rotate, and the impeller rotates with the water flow. When the water flow rate is normal, the impeller's rotation speed is lower than that of the constant-speed disk, the push-button switch is not triggered by the flap, and the monitoring camera is in a low-power standby or shutdown state. However, once the water flow rate exceeds the set threshold, the impeller speed increases, driving the flap to touch the push-button switch under the support of the mounting base, thereby starting the monitoring camera. This method of actively starting the monitoring camera based on the water flow rate avoids the large amount of power consumption caused by the continuous operation of the camera, effectively reducing the overall energy consumption of the monitoring device, significantly improving the battery life, reducing the need for frequent replacement or charging in remote areas, and significantly reducing manpower and material costs. 2. The switching motor drives the switching disk to rotate, and the card block engages with the connecting block, so that the sampling box rotates with the switching disk. The closing column cooperates with the liquid inlet pipe during the rotation of the switching disk to ensure the closure of the sampling box. When the switching disk rotates to a specific position, it can be pushed out and engaged with the give way slot, so that the impeller can drive the sampling box into the water for sampling during the rotation process. At different time periods, by controlling the switching motor and the electric push rod, water samples at different times can be collected into independent sampling boxes, which effectively ensures the independence of water bodies at different time periods. When facing intermittent pollution of rivers, seasonal or tidal fluctuations in water quality, etc., representative water samples at different time periods can be accurately collected, providing reliable data for analyzing the dynamic changes of water quality over time.

At this time, the switching motor (18) drives the switching disk (19) to rotate and the electromagnet (27) is powered off, so that the electromagnet (27) is disengaged from the connection with the connecting seat (24), and the sampling box (22) is recovered.
