[0002] Water source protection refers to special protection carried out to prevent and control water source pollution and ensure the environmental quality of water sources. Flood control and drainage water conservancy structure refers to the water conservancy engineering structure designed to defend against flood invasion and remove ground water. Flood control and drainage water conservancy structure can intercept part of the flood during the flood, and then gradually discharge it after the flood peak, realizing staggered scheduling and reducing the amplitude of water level changes in the downstream river channel. In terms of drainage, it can control the inflow and outflow of water, discharge the water in time, and prevent the occurrence of waterlogging disasters.

[0003] The existing flood control and drainage water conservancy structure releases water by opening the gates.

[0024] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0025] Embodiment 1 The following is a further detailed description of the technical solution of the present invention in conjunction with the accompanying drawings and specific embodiments. Figures 1 to 4 , this application provides a flood control and drainage water conservancy structure based on water source protection, please refer to Figure 1 , Figure 2 and Figure 3 , comprising a water retaining dam body 1; a drainage channel 101 is provided inside the water retaining dam body 1, a hydraulic control gate 102 is movably installed inside the water retaining dam body 1 near the drainage channel 101, a backwater treatment chamber 105 is provided at the inner bottom of the water retaining dam body 1, a slow flow mechanism 3 is rotatably installed on one side inside the backwater treatment chamber 105, and a filtering mechanism 5 is installed on one side inside the backwater treatment chamber 105 near the slow flow mechanism 3; The slow flow mechanism 3 includes a water wheel 301, a water wheel bucket 302 and a sun gear 303. The water wheel 301 is rotatably installed on one side inside the return water treatment chamber 105, the water wheel bucket 302 is installed on the outer surface of the water wheel 301, and the sun gear 303 is installed on the outer side of one end of the water wheel 301.

[0026] Specifically, by hydraulically controlling the gate 102 to move out from the inside of the drainage channel 101, the water can be discharged, and the slow-flow mechanism 3 is used to slow the flow of water, which is convenient for the subsequent filtering mechanism 5 to process the water. When part of the water is transported to the inside of the return water treatment chamber 105, the water wheel bucket 302 will drive the water wheel 301 to rotate under the impact of the water. Through the rotation of the water wheel 301 and the water wheel bucket 302, the water can be slowed down, which is convenient for the subsequent filtering mechanism 5 to better process the water. When the water wheel 301 rotates, it will synchronously drive the sun gear 303 to rotate, and then the rotational power can be transmitted to the subsequent threaded rod 4, thereby maximizing the utilization of energy.

[0027] Please refer to Figure 1A driving assembly 202 is installed on both sides of the top of the water retaining dam body 1. The driving assembly 202 consists of a motor and a transmission gear plate. The transmission gear plate is installed at the output end of the motor. A corresponding transmission tooth groove is provided inside the metal mesh 2 close to the driving assembly 202, and the transmission gear plate cooperates with the transmission tooth groove. A metal mesh 2 is movably installed on the front of the water retaining dam body 1, and a collecting frame 201 is provided at the bottom of the metal mesh 2.

[0028] Specifically, in order to block large foreign objects in the water, the metal mesh 2 can be used to block larger foreign objects in the water. When the driving component 202 works and engages with the metal mesh 2 for transmission, the metal mesh 2 can be prompted to move upward. At this time, the foreign objects blocked by the metal mesh 2 in the water will enter the interior of the collection frame 201. Later workers can directly carry out centralized processing of the foreign objects collected inside the collection frame 201.

[0029] Please refer to Figure 3 A control valve 103 is installed on one side of the top of the dam body 1.

[0030] Specifically, in order to realize the delivery of part of the water to the interior of the return water treatment chamber 105 , the worker opens the control valve 103 so that part of the water can be delivered to the interior of the return water treatment chamber 105 for water treatment.

[0031] Please refer to Figure 3 and Figure 4 A threaded rod 4 is rotatably installed on one side of the return water treatment chamber 105 close to the water wheel 301, a planetary gear 401 is installed on the outside of one end of the threaded rod 4, the planetary gear 401 is meshed with the sun gear 303 for transmission, a sleeve 402 is threadedly sleeved on the outer side of the threaded rod 4, a cleaning plate 405 is fixedly installed on the side of the sleeve 402 away from the water wheel 301, and one side of the cleaning plate 405 is in contact with the filtering mechanism 5.

[0032] Please refer to Figure 2 and Figure 3 A sewage discharge channel 106 is installed inside the dam body 1 near the cleaning plate 405.

[0033] Specifically, in order to achieve the treatment of the filter mechanism 5, when the water wheel 301 drives the sun gear 303 to rotate, the sun gear 303 and the planetary gear 401 are meshed for transmission, which will drive the threaded rod 4 to rotate, prompting the sleeve 402 on the outside of the threaded rod 4 to move. When the sleeve 402 drives the cleaning plate 405 to move, the filter mechanism 5 can be directly cleaned through the cleaning plate 405, thereby avoiding excessive foreign matter clogging the filter mechanism 5 and affecting the treatment of water by the filter mechanism 5. The cleaned foreign matter can be regularly discharged through the sewage channel 106.

[0034] Please refer to Figure 3The filtering mechanism 5 includes a metal screen 501 and a purification component 502. The metal screen 501 is installed on the side of the return water treatment chamber 105 close to the slow flow mechanism 3, and the purification component 502 is installed on the side of the metal screen 501 away from the slow flow mechanism 3. The purification component 502 is zeolite, which has adsorption, ion exchange, catalysis, acid and heat resistance and other properties.

[0035] Please refer to Figure 1 A circulation pump 104 is installed inside the backwater treatment chamber 105 near the front of the dam body 1.

[0036] Specifically, in order to process the water, the water can be initially filtered through the metal screen 501, and the water can be filtered again through the purification component 502, and then the treated water in the return water treatment chamber 105 can be transported out again for use through the circulation pump 104.

[0037] Please refer to Figure 3 and Figure 4 A spring cylinder 403 is installed on the outside of the sleeve 402. The spring cylinder 403 consists of a spring and a cylinder body. One end of the spring is connected to the cylinder body, and the other end is connected to the sleeve 402. A scraper 404 is installed on the side of the spring cylinder 403 close to the water wheel bucket 302.

[0038] Specifically, in order to process the water wheel bucket 302, when the threaded rod 4 drives the outer sleeve 402 to move, it will synchronously drive the spring tube 403 and the scraper 404 to move. The inner wall of the water wheel bucket 302 can be processed by the movement of the scraper 404 to avoid long-term use affecting the water treatment effect of the device in the later stage. When the water wheel bucket 302 rotates and shifts, it will squeeze the scraper 404, causing the spring tube 403 to rotate on the outer ring of the sleeve 402, thereby preventing the scraper 404 from being squeezed and damaged by the water wheel bucket 302.

[0039] A construction method of a flood control and drainage water conservancy structure based on water source protection according to the above, comprising the following steps: S1. Conduct geological surveys on the construction site before construction to understand the topography and hydrogeological conditions to ensure construction safety. According to the geological survey results, carry out foundation excavation and concrete pouring to build the foundation structure of the flood control embankment. On the foundation, construct the main body of the water retaining dam 1, and adopt the layered filling and compaction method to ensure the stability of the main body of the water retaining dam 1; S2. Dig a drainage channel 101 inside the dam body 1, and set a sewage channel 106 and a backwater treatment chamber 105 to ensure that the drainage system is unobstructed; S3, the larger foreign matter in the water is blocked by the metal leakage net 2, and the water is treated by the slow flow mechanism 3 and the filtering mechanism 5; S4. Vegetation restoration can be carried out on the outside of the water retaining dam body 1, and plants with strong flood resistance, such as poplar and sea buckthorn, can be planted; S5. Install isolation and protection fences and set up warning signs in the first-level protection zone of the water source.

[0040] Working principle: The metal mesh 2 can be used to block larger foreign objects in the water, and the hydraulically controlled gate 102 can be moved out of the drainage channel 101 to discharge the water. At the same time, the control valve 103 is opened to transport part of the water to the return water treatment chamber 105. At this time, the water wheel bucket 302 will drive the water wheel 301 to rotate under the impact of the water. The rotation of the water wheel 301 and the water wheel bucket 302 can slow the flow of the water. Then, the water is preliminarily filtered through the metal screen 501, and the water can be filtered again through the purification component 502. Finally, the treated water in the return water treatment chamber 105 can be transported out again for use through the circulation pump 104.

[0041] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
