Description

Technical Field

[0001] This utility model relates to the field of farmland water conservancy equipment technology, and in particular to a farmland water conservancy circulating irrigation and drainage device. Background Technology

[0002] With the continuous advancement of agricultural modernization and intensive water resource management, water-saving irrigation technology has become crucial for ensuring food security and sustainable agricultural development. Among numerous water-saving technologies, combining irrigation and drainage in farmland to construct a water resource recycling system is a highly promising development direction. These systems typically collect excess water or rainfall from fields through facilities such as reservoirs, perform simple sedimentation treatment, and then reuse it as irrigation water, thereby significantly improving water resource utilization efficiency.

[0003] However, in practical applications, the aforementioned recycling system faces an unavoidable technical bottleneck. Because the water discharged from farmland inevitably carries large amounts of silt, fallen leaves, and other impurities, these impurities continuously settle and accumulate in the reservoir, eventually forming a thick layer of silt at the bottom. This silt accumulation not only continuously pollutes the water quality, but more seriously, it significantly reduces the effective storage capacity of the reservoir. Furthermore, the silt is easily sucked into the pumps during operation, leading to pump wear, irrigation network blockage, and ultimately, a substantial reduction in the stability and lifespan of the entire recycling irrigation system.

[0004] To address the problem of silt accumulation, the current common practice is to conduct periodic maintenance shutdowns, using manual shoveling or heavy machinery for dredging. This method is not only cumbersome and inefficient, requiring significant manpower and material resources, but also disrupts the normal operation of the entire irrigation and drainage system, impacting agricultural seasons. Therefore, existing circulating irrigation and drainage systems lack an integrated design that can coordinate with the water circulation process and automatically complete silt removal, resulting in high maintenance costs, low automation, and an inability to achieve truly long-term stable operation.

[0005] Therefore, this utility model proposes a farmland water conservancy circulating irrigation and drainage device to overcome the shortcomings of the prior art. Utility Model Content

[0006] The purpose of this application is to provide a farmland irrigation and drainage system that improves the existing farmland irrigation and drainage systems, which cannot recycle water resources and have difficulty automatically cleaning sediment in the reservoir.

[0007] The agricultural irrigation and drainage system provided in this application adopts the following technical solution: A farmland irrigation and drainage system includes: a water storage tank and a circulation component. The circulation component includes a bidirectional water pump and a water supply network connected to the bidirectional water pump, and a cleaning component installed in the water storage tank. The cleaning component includes a mounting frame spanning and fixed above the opening of the water storage tank, a motor, a sprocket, a chain, and a rubber scraper. The motor is vertically mounted on the mounting frame. The sprockets are spaced apart and rotatably connected to the bottom of the mounting frame. The motor drives one of the sprockets to rotate. The chain is meshed around the sprocket. The rubber scraper is fixedly connected to the chain by a fixing block, and the scraping blade of the rubber scraper is slidably attached to the bottom of the water storage tank.

[0008] Preferably, sliders are fixedly connected to both ends of the rubber scraper, and guide grooves are provided on the opposite inner walls of the water storage tank along the movement direction of the chain, with the sliders slidingly engaged in the guide grooves.

[0009] Preferably, the bottom of the water storage tank has a slag collection trough formed by a recess at the end of the movement stroke of the rubber scraper.

[0010] Preferably, a drain valve is installed at the lowest point of the bottom of the slag collection tank.

[0011] Preferably, a filter structure is provided in the water storage tank and at the water inlet of the bidirectional water pump. The filter structure consists of a stainless steel filter screen, a sand and gravel filter layer, and a water-permeable baffle from top to bottom.

[0012] Preferably, a sedimentation layer is defined between the permeable baffle and the bottom of the water storage tank, and the rubber scraper is located within the sedimentation layer to scrape the bottom surface of the sedimentation layer.

[0013] Preferably, the water supply pipeline is branched with irrigation branch pipes and drainage branch pipes.

[0014] Preferably, both the irrigation branch pipe and the drainage branch pipe are equipped with manual butterfly valves.

[0015] In summary, this application includes at least one of the following beneficial technical effects: 1. This utility model solves the problems of water resources not being able to be recycled and the need for manual cleaning of sediment in existing farmland water conservancy facilities, high maintenance costs, and low automation by setting up a circulation component and a cleaning component, and by having the cleaning component drive a chain driven by a motor to move a rubber scraper at the bottom of the water storage tank. It achieves the effects of saving water resources, automatically removing silt, reducing manual maintenance costs, and ensuring the long-term stable operation of the device.

[0016] 2. This utility model solves the problem that the cleaning scraper may deflect or shake during movement, resulting in incomplete scraping or equipment jamming, by setting a slider on the rubber scraper and opening a guide groove on the inner wall of the water storage tank to match it. It achieves the effect of improving the stability and guiding accuracy of the rubber scraper and ensuring the dredging effect. Attached Figure Description

[0019] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0020] A farmland irrigation and drainage system, referring to Figures 1-4The system includes a water storage tank 1, a circulation component 2 located outside the water storage tank 1, and a cleaning component 3 located inside the water storage tank 1. The water storage tank 1 serves as the water storage and purification platform for the entire system. The circulation component 2 enables bidirectional water flow between the water storage tank 1 and the farmland. The cleaning component 3 automatically removes sediment from the bottom of the water storage tank 1. Specifically, the cleaning component 3 includes a mounting frame 301, which spans and is fixed above the opening of the water storage tank 1. A motor 302 is vertically mounted on the mounting frame 301. At least two sprockets 303 are spaced apart and rotatably connected to the bottom of the mounting frame 301. One of the sprockets 303... The rotating shaft is coaxially fixedly connected to the output shaft of the motor 302, so that it is driven to rotate by the motor 302. Another sprocket 303 rotates as a driven wheel. The cleaning component 3 also includes a chain 304, which is meshed with multiple sprockets 303. When the motor 302 is working, it drives the chain 304 to rotate in a cycle through the sprockets 303. A rubber scraper 306 is fixedly connected to the chain 304 through a fixing block 305. The rubber scraper 306 moves back and forth on the bottom of the water storage tank 1 as the chain 304 moves. The scraping blade of the rubber scraper 306 can slide against the bottom of the water storage tank 1 to scrape off the silt and impurities at the bottom of the tank. Both ends of the rubber scraper 306 are fixedly connected to sliders 307. Correspondingly, guide grooves are provided on the inner walls of the reservoir 1 along the movement direction of the chain 304. In the assembled state, the sliders 307 slide in the guide grooves. Through the sliding guide cooperation between the sliders 307 and the guide grooves, it can be ensured that the rubber scraper 306 moves smoothly along the preset path under the drive of the chain 304, effectively avoiding deflection or jamming during the scraping process, thereby ensuring the reliability and continuity of the dredging work. In order to realize the centralized collection and discharge of sludge after scraping, a sludge collection trough 308 is formed in the bottom of the reservoir 1 at the end of the movement stroke of the rubber scraper 306. When the rubber scraper 306 reciprocates, it will push the impurities at the bottom of the reservoir into the sludge collection trough 308. A drain valve 309 is installed at the lowest point of the bottom of the sludge collection trough 308. When the sludge in the sludge collection trough 308 accumulates to a certain extent, the drain valve 309 can be opened to discharge the sludge. In order to purify the water entering the reservoir 1, a filter structure is installed in the reservoir 1 at the suction port of the bidirectional water pump 201. The filter structure consists of a stainless steel filter screen 206, a sand and gravel filter layer 207, and a permeable baffle 208 from top to bottom. The stainless steel filter screen 206 is used to intercept larger impurities in the water, the sand and gravel filter layer 207 is used to further filter fine silt, and the permeable baffle 208 provides support and isolation for the sand and gravel filter layer 207. A sedimentation layer 209 is defined between the permeable baffle 208 and the bottom of the reservoir 1. The water that has been initially purified by the filter structure can be allowed to settle here, allowing even smaller impurities to settle to the bottom of the reservoir. The rubber scraper 306 is located in the sedimentation layer 209 and is used to scrape the bottom surface of the sedimentation layer 209 to collect the settled impurities. To achieve irrigation and drainage of farmland, the water supply network 202 is branched with irrigation branch pipes 203 and drainage branch pipes 204. Both irrigation branch pipes 203 and drainage branch pipes 204 are equipped with manual butterfly valves 205. By operating the manual butterfly valves 205, the opening or closing of specific branch pipes can be easily controlled, thereby achieving precise irrigation and drainage control for different fields.

[0021] Working principle: When irrigation is needed, the manual butterfly valve 205 on the irrigation branch pipe 203 is opened and the bidirectional water pump 201 is started. When the water in the reservoir 1 is pumped out, it will pass through the stainless steel filter screen 206, the sand and gravel filter layer 207 and the permeable baffle 208 in sequence to filter impurities. The purified water is pumped into the water supply network 202 by the bidirectional water pump 201 and finally flows to the farmland from the irrigation branch pipe 203. When drainage is needed, the manual butterfly valve 205 on the drainage branch pipe 204 is opened. The bidirectional water pump 201 pumps the water accumulated in the field back to the water supply network 202 through the drainage branch pipe 204 and then pumps it back to the reservoir 1. The returned water is also purified by the above-mentioned filtration structure and enters the sedimentation layer 209 for static sedimentation, thus forming an effective cycle of water resources. When the sediment layer 209 at the bottom of the water storage tank 1 needs to be cleaned, the motor 302, which is mounted on the mounting frame 301 above the water storage tank 1, is started. The motor 302 drives the sprocket 303, which is coaxially fixed to it, to rotate. The sprocket 303 drives other sprockets 303 to rotate synchronously through the meshing chain 304, thereby driving the chain 304 to circulate. The rubber scraper 306 fixed on the chain 304 moves back and forth at the bottom of the tank. During the movement, the sliders 307 at both ends of the rubber scraper 306 slide in the guide grooves on the inner wall of the water storage tank 1. The guide structure ensures the stability and accuracy of the movement of the rubber scraper 306. The rubber scraper 306 scrapes and collects the sludge and impurities at the bottom of the sediment layer 209 into the sludge collection tank 308. After the sludge accumulates to a certain extent, the drain valve 309 at the bottom of the sludge collection tank 308 is opened to complete the automatic sewage discharge.
