Description

Technical Field

[0001] This application relates to the field of irrigation technology in water conservancy projects, specifically a water-saving irrigation device for water conservancy projects. Background Technology

[0002] Sprinkler irrigation is an irrigation method that uses water pumps and pipeline systems or the drop of natural water sources to spray water with a certain pressure into the air, dispersing it into small water droplets or forming a mist that falls onto plants and the ground. Sprinkler irrigation equipment consists of water inlet pipes, pumps, water delivery pipes, water distribution pipes, and sprinklers, and can be fixed, semi-fixed, or mobile.

[0003] According to Chinese patent publication number CN222128933U, a water-saving irrigation device for water conservancy projects includes a water supply pipe and a sprinkler pipe. The end of the water supply pipe is fixedly connected to the sprinkler pipe, which is arranged horizontally. The advantages of this invention are: firstly, it features a rotatable baffle structure. When the inner side of the baffle abuts against the baffle rod, the baffle is in its working position, located above and to the side of the sprinkler pipe. This prevents the water mist sprayed from the sprinkler head from diffusing into the air or elsewhere. The baffle can block most of the diffusing water mist, which gathers on the inner side of the baffle and drips back onto the crops or soil, thus achieving water conservation. Secondly, even if some of the water sprayed onto the crops or ground evaporates, the evaporated water is blocked by the baffle, gathers on the inner side of the baffle, and drips back onto the crops or soil along the baffle and the guide channel, further achieving water conservation and preventing excessive evaporation and diffusion of irrigation water.

[0004] The solution mainly uses a rotating baffle structure to intercept the diffused water mist, allowing the water mist to re-gather on the inside of the baffle for reuse. However, the baffle is located at a high position, which can block sunlight when irrigating crops, affecting their normal growth. Even if the baffle is made of a transparent plate with high light transmittance, workers will still need to frequently clean the mud and dust on the baffle.

[0005] Therefore, this application provides a water-saving irrigation device for water conservancy projects to solve the above-mentioned problems. Utility Model Content

[0006] This application provides a water-saving irrigation device for water conservancy projects, which aims to solve the problem mentioned in the background art that when irrigating crops, the baffle will block sunlight and affect the normal growth of crops.

[0007] To achieve the above objectives, this application provides the following technical solution: a water-saving irrigation device for water conservancy projects, comprising a track frame and two first sliders slidably mounted on the track frame, each of the first sliders being fixedly mounted with a shaft, the lower end of the shaft being provided with an irrigation component, and the shaft being provided with a water-saving mechanism;

[0008] The water-saving mechanism includes a bushing fitted on a shaft and a honeycomb mesh plate set on the bushing. The honeycomb mesh plate has a plurality of honeycomb holes. A second guide rail is fixedly connected to the end of the honeycomb mesh plate away from the bushing. A cloth storage box is fixedly installed at the end of the bushing away from the track frame. A drainage groove is formed on the honeycomb mesh plate. The irrigation component consists of a water supply pipe, a sprinkler pipe, and a sprinkler head, thereby providing atomized spraying to crops. The connection method is existing technology.

[0009] Preferably, a first guide rail seat connected to the honeycomb mesh plate is fixedly connected to the bushing. Both the first guide rail seat and the second guide rail seat are provided with sliding grooves. The double-rail design ensures that the curtain is evenly stressed when it is unfolded, avoiding the decrease in interception efficiency caused by wrinkles. The inner wall of the sliding groove is polished to reduce sliding resistance.

[0010] Preferably, a winding shaft is rotatably connected to the storage box, a hydrophilic fabric curtain is fitted onto the winding shaft, a fixing plate is fixedly connected to the end of the hydrophilic fabric curtain away from the winding shaft, and a handle is fixedly installed on the fixing plate.

[0011] Preferably, one end of the winding shaft passes through the fabric storage box and is fixedly mounted with a wheel.

[0012] Preferably, a second slider is fixedly installed at both ends of the fixed plate. The second slider at the end away from the wheel is slidably connected to the groove on the first guide rail seat, and the second slider at the end closer to the wheel is slidably connected to the groove on the second guide rail seat.

[0013] Preferably, the lower ends of the first guide rail seat and the second guide rail seat are threaded with positioning screws, and the lower end of the second slider is provided with a round hole that matches the positioning screws.

[0014] This water-saving device allows staff to manually rotate a wheel to retract the fabric curtain into the storage box, reducing light shading. By installing a first guide rail on the bushing and fixing the honeycomb mesh plate with the first guide rail, the honeycomb mesh plate's honeycomb holes intercept atomized water droplets, reducing evaporation loss.

[0015] At night, the water-saving device can be manually pulled towards one end of the first guide rail by holding the handle, so that the hydrophilic curtain can be fully opened. At night, it can collect dew and guide it to the roots of crops through the drainage channel to supplement the rainfall. Attached Figure Description

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] This embodiment provides a water-saving irrigation device for water conservancy projects, such as... Figure 1-7 As shown, the water-saving device includes a track frame 1 and two first sliders 2 slidably mounted on the track frame 1. Each first slider 2 is fixedly mounted with a shaft, and an irrigation component is provided at the lower end of the shaft. A water-saving mechanism is provided on the shaft.

[0027] The water-saving mechanism includes a bushing 3 mounted on a shaft and a honeycomb mesh plate 4 mounted on the bushing 3. The honeycomb mesh plate 4 has several honeycomb holes. A second guide rail seat 5 is fixedly connected to the end of the honeycomb mesh plate 4 away from the bushing 3. A cloth storage box 6 is fixedly installed at the end of the bushing 3 away from the track frame 1. A drainage groove 41 is provided on the honeycomb mesh plate 4.

[0028] Specifically, the bushing 3 can rotate along the shaft, the honeycomb mesh plate 4 is connected to the track frame 1 through the bushing 3, the second guide rail seat 5 supports the end of the mesh plate, the storage box 6 is used to store the hydrophilic fabric curtain 8, the honeycomb holes of the honeycomb mesh plate 4 intercept atomized water droplets to reduce evaporation loss, and at the same time, it can avoid blocking sunlight. The storage box 6 protects the fabric curtain 8 from aging due to direct sunlight. The drainage channel 41 has a V-shaped cross section with a spacing of 20mm and a hydrophilic film coated on the surface to ensure that the dew drops are quickly guided to the crops below.

[0029] A first guide rail seat 31, which is connected to the honeycomb mesh plate 4, is fixedly connected to the bushing 3. Both the first guide rail seat 31 and the second guide rail seat 5 are provided with sliding grooves.

[0030] More specifically, the grooves of the first guide rail seat 31 and the second guide rail seat 5 provide a sliding path for the second slider 81, ensuring the stability of the curtain 8 when it is unfolded and rolled up.

[0031] A winding shaft is rotatably connected to the fabric storage box 6. A hydrophilic fabric curtain 8 is fitted onto the winding shaft. A fixing plate 82 is fixedly connected to the end of the hydrophilic fabric curtain 8 away from the winding shaft. A handle 83 is fixedly installed on the fixing plate 82. A wheel 7 is fixedly installed through the fabric storage box 6 at one end of the winding shaft.

[0032] Furthermore, the rotation of the wheel 7 drives the winding shaft, and the hydrophilic curtain 8 is retracted from the fabric storage box 6. The handle 83 facilitates manual operation to pull the hydrophilic curtain 8 outward. At night, the curtain 8 is unfolded to collect dew, and during the day, it is rolled up to reduce shading. When the collected dew is retracted, the dew will detach from the hydrophilic curtain 8 and drip onto the honeycomb mesh plate 4. The curtain 8 is made of polyester fiber and hydrophilic coating composite. The honeycomb mesh plate 4 and the curtain 8 work together to reduce the evaporation rate of atomized water and improve the water saving rate. The fabric storage box 6 is made of engineering plastic with silicone sealing rings on the edges. The protection level is IP65, which can prevent rainwater from seeping in.

[0033] The fixed plate 82 has a second slider 81 fixedly installed at both ends. The second slider 81 at the end away from the wheel 7 is slidably connected to the groove on the first guide rail seat 31, and the second slider 81 at the end closer to the wheel 7 is slidably connected to the groove on the second guide rail seat 5.

[0034] It should be noted that the edge of the wheel 7 is provided with anti-slip texture. When rotated manually, it drives the winding shaft to rotate, thereby realizing the recovery of the hydrophilic curtain 8. The second slider 81 has an L-shaped structure and forms an embedded sliding with the chute. The synchronous movement of the sliders at both ends ensures that the curtain 8 is unfolded flat. The hydrophilic curtain 8 can collect dew at night and guide it to the roots of crops through the drainage channel 41 to supplement the rainfall.

[0035] The lower ends of the first guide rail seat 31 and the second guide rail seat 5 are threaded with positioning screws 32, and the lower end of the second slider 81 is provided with a round hole that matches the positioning screws 32.

[0036] It is worth mentioning that the positioning screw 32 is screwed into the round hole of the second slider 81, and the position of the curtain 8 is locked by friction, preventing the curtain 8 from being blown by the wind when it is unfolded.

[0037] During use, during the day, the staff manually rotates the wheel 7 to retract the curtain 8 into the storage box 6 to reduce shading. By installing the first guide rail seat 31 on the bushing 3 and fixing the honeycomb mesh plate 4 with the first guide rail seat 31, the honeycomb holes of the honeycomb mesh plate 4 intercept the atomized water droplets, reducing evaporation loss and also preventing the crops from being exposed to sunlight. At night, the staff manually holds the handle 83 and pulls it towards one end of the first guide rail seat 31 to fully unfold the hydrophilic curtain 8. At night, dew can be collected and guided to the roots of the crops through the drainage channel 41 to supplement the rainfall.

[0038] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
