Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy and flood prevention, and in particular to a water conservancy and flood prevention early warning and emergency integrated device. Background Art

[0002] Flood is a common natural disaster, which not only threatens people's property safety, but also endangers people's personal safety, and in severe cases will cause irreparable losses. Therefore, effective flood control and drainage has important practical significance.

[0003] The existing flood control system is mainly designed and optimized from the perspective of the flood control equipment itself. For example, a multi-stage cascade method is used to improve flood discharge efficiency, and the flood control gate structure is improved to improve flood control reliability; or reusable flood control bags and flood control wells connected to surface runoff are designed.

[0004] However, the above-mentioned flood control system only works when floods occur and takes corresponding measures, but cannot provide early warning for flood disasters. Although relevant research has introduced information monitoring equipment into the flood warning process, all kinds of equipment rely on external power supply, and the power system is the first to be damaged when floods occur; thus, there are obvious defects in actual flood warning. At the same time, it does not consider how to effectively carry out emergency measures such as rescue when floods occur, so it is impossible to effectively reduce the safety losses caused by floods. Summary of the invention

[0007] Furthermore, the electrocatalytic coating is a chlorine evolution coating with a potential of 1.2V.

[0008] Furthermore, when the buoyancy sensor is triggered, the corresponding water depth increment range of the target water body is: not less than 0.8m.

[0009] Furthermore, adjacent sides of adjacent folded blades are arranged to overlap each other.

[0016] This technical solution considers the overall perspective of flood prevention.

At the same time, the control center processes the infrared image to efficiently identify and confirm the trapped personnel, and combines the image coordinates reported synchronously by the infrared detector to quickly confirm the location of the personnel. In the actual search process of the personnel, the lighting unit is used to illuminate the target area to quickly lock the personnel. Considering that the operation of the entire system needs to be based on electricity, the energy module is set in a targeted manner to ensure the independent operation of the device and the normal operation when the external power is damaged. Specifically, the energy module continuously collects water, wind and solar energy and converts them into electrical energy for storage to ensure power supply reliability. An emergency output interface is also provided on the power storage box to realize the power supply function for key equipment during personnel search and rescue. Furthermore, considering that the photovoltaic power generation panel is the main power generation part, but it is easily eroded by rainwater, etc., a corresponding photovoltaic protection part is provided. Specifically, the photovoltaic protection part realizes effective shielding of rainwater under the synergistic effect of the protection function of the first blade and the buffering function of the second blade. At the same time, the upward movement of the blades before unfolding can also effectively avoid the height dimension being too large and affecting the operational reliability of the entire device.

[0023] Effective flood control and drainage has important practical significance for protecting people's property safety and personal safety. However, the existing flood control system is mainly designed and optimized from the flood control equipment itself, and thus has technical problems such as single energy supply, limited monitoring means, and insufficient emergency function. Therefore, this embodiment aims to provide a water conservancy flood control early warning and emergency integrated device to improve the above defects at the same time.

[0024] The integrated water conservancy flood prevention warning and emergency device described in this embodiment is specifically introduced below in conjunction with the accompanying drawings.

[0025] Combination Figures 1 to 4 As shown, the device includes an energy module, a monitoring module and an emergency module that cooperate with each other.

[0026] In terms of specific structural settings, the energy module includes a power storage box 1, a hydroelectric generator 2, a wind turbine 3, a photovoltaic panel 4, and a photovoltaic protection part 5. Among them, the hydroelectric generator 2, the wind turbine 3, the photovoltaic panel 4, and the photovoltaic protection part 5 are all electrically connected to the power storage box 1. Specifically, the power storage box 1 uses a high-performance lithium battery pack or other new energy storage equipment, which has a large capacity and stable charging and discharging performance. The power storage box 1 also includes an emergency output interface, so that when the external power is interrupted, it can provide emergency power support for important surrounding flood control equipment, such as drainage pumps, flood gate control devices, etc., to ensure that these equipment operate normally at critical moments and maintain the basic functions of flood control projects; it can also provide sufficient power when the power demand of other components in the device increases.

[0027] The hydroelectric generator 2 is deployed in the water body, including a main body 2.1 and a flow deflector 2.2. The flow deflector 2.2 is arranged on the main body 2.1 and is composed of a honeycomb FRP grid coated with an electrocatalytic coating. In this embodiment, the electrocatalytic coating is a chlorine-evolving coating with a potential of 1.2V, and the porosity of the coating is 65%±5%. The main body includes a shell, and a water inlet 2.1c and a water outlet 2.1d are provided on the shell. The shell is equipped with an impeller 2.1b and a motor 2.1a. The water inlet 2.1c and the water outlet 2.1d are both opened corresponding to the impeller 2.1b, and the impeller 2.1b is connected to the motor 2.1a through a rotating shaft. When the water flows down and impacts the impeller 2.1b, it will drive the rotor of the motor 2.1a to rotate, and the potential energy of the water flow is converted into electrical energy and stored in the power storage box 1. The flow deflector 2.2 can be used to inhibit biological fouling, thereby improving the power generation efficiency.

[0028] For the wind turbine 3 and the photovoltaic panel 4, when working during the day, the photovoltaic panel 4 converts solar energy into electrical energy, and the wind blades of the wind turbine 3 convert wind energy into electrical energy and store it in the power storage box 1; when working in the evening, the photovoltaic panel 4 no longer stores solar energy or the stored solar energy is low, and the wind blades of the wind turbine 3 continue to convert wind energy into electrical energy and store it in the power storage box 1.

[0029] Considering the easy wear and tear of the photovoltaic power generation panel 4, the photovoltaic protection part 5 is correspondingly arranged to include a first driver, a second driver, a third driver, a support rod 5.1, a rain sensor 5.2, a buoyancy sensor, a plurality of telescopic rods 5.4 arranged one by one, and a folding blade 5.3. Among them, any folding blade 5.3 includes a first blade 5.3a and a second blade 5.3b that are movably connected. Among them, the inner side wall of the first blade 5.3a is provided with a first long groove, and the inner side wall of the second blade 5.3b is provided with a second long groove. The first long groove and the second long groove are respectively provided with two ends of the folding rod. The input end of the third driver is electrically connected to the rain sensor 5.2 and the buoyancy sensor, and the output end is electrically connected to each folding rod. The support rod 5.1 is arranged on one side of the photovoltaic power generation panel, including a threaded inner rod 5.1a and a sleeve 5.1b. The input end of the first driver is electrically connected to the rain sensor 5.2 and the buoyancy sensor, and the output end is electrically connected to the sleeve 5.1b. The free ends of the first blades 5.3a are movably mounted on the upper end of the sleeve 5.1b at intervals along the circumferential direction; each telescopic rod 5.4 is arranged in one-to-one correspondence with each first blade 5.3a, and the two ends of any telescopic rod 5.4 are respectively fixed to the sleeve 5.1b and the corresponding first blade 5.3a. The input end of the second driver is electrically connected to the rain sensor 5.2 and the buoyancy sensor, and the output end is electrically connected to each telescopic rod 5.4.

[0030] In specific implementation, when the rain sensor 5.2 directly detects rainfall or the water level rises based on the buoyancy sensor, the support rod 5.1 is triggered to spirally rise to the highest position under the action of the first driver, and at the same time, the second driver drives the telescopic rod 5.4 to extend so that each first blade 5.3a is fully opened from bottom to top, and the third driver drives the folding rod to open the second blade 5.3b. At this time, under the protective effect of the first blade 5.3a (the opening angle of the first blade 5.3a reaches a maximum of 170 degrees) and the buffering effect of the second blade 5.3b (because the second blade 5.3b is vertically downward when unfolded, and its lowermost end is lower than the lowermost end of the photovoltaic power generation panel 4, it can block the rainwater flowing down along the first blade, thereby forming a buffer), the direct impact and erosion of rainwater on the photovoltaic power generation panel 4 will be effectively reduced. When there is no rain, under the action of each driver, the second blade 5.3b and the first blade 5.3a will be closed under the action of the folding rod and the telescopic rod, and the support rod 5.1 returns to the initial position. The support rod 5.1 is used to prevent the photovoltaic protection part 5 from causing the entire device to be too large in height, thereby affecting its reliability during use.

[0031] As a preferred embodiment, the depth increment range of the target water body corresponding to the buoyancy sensor being triggered is set to be no less than 0.8m. This ensures that the adverse effects of long-term rainfall on the photovoltaic panel 4 are prevented when the rainfall per unit area is small and the rain sensor cannot be effectively triggered. In order to ensure the reliability of the folding blades 5.3 in shielding rainwater when unfolded, the adjacent sides of adjacent folding blades are arranged to overlap each other, thereby preventing rainwater from dripping onto the photovoltaic panel 4 from the gaps between the blades.

[0032] The monitoring module includes a radar water level meter 6, several flow velocity detectors and several soil moisture detectors 7 electrically connected to the power storage box. The radar water level meter 6, several flow velocity detectors and several soil moisture detectors 7 all communicate with the control center to trigger an early warning when the water level value, any flow velocity value or any soil moisture value exceeds the warning value. Specifically, the detection depth of each soil moisture detector 7 is different, and each flow velocity detector is deployed in a different flow section of the target water body. As a specific implementation method, the radar water level meter 6 is installed on the shore or dam of a water body such as a river, lake, or reservoir, and adopts high-frequency radar technology to emit electromagnetic waves to the water surface and receive reflected waves, thereby transmitting water level data to the control center in real time, and when the water level exceeds the preset warning value, an early warning signal is immediately triggered. The soil moisture detector 7 is buried in the soil in an area prone to flood disasters, and the parameters such as the dielectric constant of the soil are measured by sensors to accurately obtain soil moisture information; setting multiple soil detection depths can fully understand the water content of soil at different levels. When soil moisture reaches a critical value that may cause landslides, mudslides and other disasters, an early warning is issued in time to provide a basis for taking preventive measures in advance. The flow velocity detector is placed in water channels such as rivers and channels, and uses the Doppler effect or other advanced measurement principles to accurately measure the flow velocity of water bodies; it can adapt to different flow velocity ranges, from slow flow to rapid flow, and can accurately measure and transmit data in real time. Once the flow velocity changes abnormally, such as exceeding the safe flow velocity range, the early warning mechanism is quickly activated to indicate possible flood risks.

[0033] The emergency module includes an infrared detector 8 and a lighting unit electrically connected to the power storage box 1. The infrared detector 8 is deployed on the rotating mechanism to detect different directions, and communicates with the control center to upload real-time infrared images and detection coordinates. The rotating mechanism in this embodiment is a spherical movable part. The control center is integrated with an image processing algorithm for identifying real-time infrared images. As a specific implementation method, the infrared detector 8 uses infrared thermal imaging technology to detect heat signals emitted by the human body in darkness or when vision is obstructed, and cooperates with the image processing algorithm of the control center to effectively identify trapped persons and confirm the trapped position. At the same time, it is equipped with a high-brightness lighting unit, which can automatically turn on the lighting after confirming the position of the trapped person, providing a clear field of view for rescue work and ensuring that rescuers can quickly and accurately implement rescue operations.

[0034] In order to facilitate the installation of various functional components in the entire device, the device is also provided with an installation module. The installation module includes a base 9 and a mounting rod 10. Each soil moisture detector 7 is deployed at different heights on the side wall of the base 9, and the base 9 is buried in the soil. The power storage box 1 is placed on the upper end surface of the base 9, and the mounting rod 10 is placed on the upper end surface of the power storage box 1. Specifically, the mounting rod 10 is a hollow structure to accommodate power cables and communication cables, and is connected to the interior of the power storage box 1; the photovoltaic power generation panel 4 is installed on the upper end of the mounting rod 10. The installation module also includes a fixing rod 11, one end of the fixing rod 11 is fixed to the mounting rod 10, and the other end is a rotating mechanism. The infrared detector 8 is installed on the rotating mechanism, and the radar water level meter 6 is fixed on the side wall of the fixing rod 11.

[0035] Based on this, in order to facilitate the installation of the wind turbine 3, for the support rod 5.1, the inner rod 5.1a is designed to penetrate the sleeve 5.1b; the wind turbine 3 is installed on the upper end surface of the inner rod 5.1a.

[0036] In summary, it can be seen that the device described in this embodiment supplies power to the monitoring module and the emergency module through the energy module to realize the independent operation of the entire device and ensure the normal operation of the entire device when the power supply system is damaged due to a disaster. At this time, the radar water level gauge, soil moisture detector and flow velocity detector of the monitoring module continuously collect data and send the data to the control center through wireless transmission technology. The control center has a built-in intelligent analysis system to analyze and process the data in real time and compare it with the preset threshold. When the data exceeds the normal range, early warning information is immediately issued to relevant personnel in various ways (such as sound and light alarms, SMS notifications, etc.). After the flood occurs, the emergency module is started, and the infrared detector and the lighting unit work together with the image processing algorithm of the control center to search for trapped persons and lock the position of trapped persons; at the same time, the emergency output interface of the power storage box supplies power to key equipment to ensure the smooth implementation of rescue work. In this way, the full process intelligent management of flood control is realized, and the efficiency and intelligence level of flood control work are improved.

[0037] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. A person with ordinary knowledge in the technical field to which the present invention belongs may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the definition of the claims.
