Description

Technical Field

[0001] This utility model relates to the field of agricultural irrigation technology, and in particular to an agricultural irrigation water retention device. Background Technology

[0002] Agriculture is an industry that utilizes the growth and development patterns of plants and animals to obtain agricultural products through artificial cultivation. At the same time, agriculture is also a pillar industry supporting national economic construction and development. Irrigation is necessary in agricultural production to ensure sufficient water for crop growth. In the field of agricultural irrigation, water storage and water level regulation devices are crucial infrastructure for ensuring the periodic water supply to crops. Traditional water storage devices often use fixed impoundment structures, controlling water levels through manual gates or simple baffles. These solutions suffer from low height regulation accuracy and poor resistance to water flow impacts. Especially during the rainy season or in high-flow irrigation scenarios, water level fluctuations can easily lead to uncontrolled water storage, affecting irrigation stability.

[0003] Secondly, in existing technologies, most filtration devices are planar filter screens (with a "I"-shaped cross-section), which have a small interception surface area. Impurities tend to accumulate in the middle of the filter screen, leading to frequent local blockages. Furthermore, manual cleaning of impurities is inconvenient, significantly increasing maintenance difficulty. Thirdly, traditional filter screens have weak resistance to deformation and are easily damaged under the impact of high-speed water flow or large particles, further reducing the lifespan of the filtration device.

[0004] To overcome the above-mentioned shortcomings, the inventor invented an agricultural irrigation water retention device. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an agricultural irrigation interception device that can achieve high height adjustment accuracy, strong resistance to water flow impact, large interception surface area, prevent impurities from accumulating in the middle of the filter screen, avoid frequent local blockage, and is very convenient for manual cleaning of impurities, reducing maintenance difficulty. The filter screen has strong resistance to deformation, ensuring the life of the filtration device.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] An agricultural irrigation water retention device includes a water storage tank and a pre-installed column. The water storage tank has a pre-installed groove on one side, a pre-installed column is installed inside the groove, an installation frame is inserted into the pre-installed column, a water retention plate is slidably connected inside the installation frame, an installation platform is fixedly installed on the top of the installation frame, a motor is fixedly positioned at the center of the top of the installation platform, installation holes are provided on both sides of the pre-installed groove, fixing pins are inserted into the installation holes, and the fixing pins penetrate the interior of the pre-installed column and the installation frame. On the water-facing side, a groove is recessed on the inner wall of the pre-installed column, into which a filter device can be embedded.

[0008] As a further implementation, the output end of the motor is threadedly connected to the screw.

[0009] As a further implementation, the bottom of the screw is rotatably connected to the damming plate.

[0010] As a further implementation, the projection of the filter device onto the horizontal plane is M-shaped.

[0011] As a further implementation, the filtration device includes a filter screen, a collection rack, and a storage net.

[0012] As a further implementation, the filter screen is V-shaped, and both ends of the filter screen are fixedly connected to the collection rack.

[0013] As a further implementation, multiple storage nets are horizontally arranged inside the collection rack, and the storage nets are fixedly connected to the collection rack.

[0014] As a further implementation, a handle is provided on the top of the filter device.

[0015] As a further implementation, the groove is set in the vertical direction.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention connects the output end of a lifting motor to a screw thread, converting the rotational motion of the lifting motor into the linear motion of the screw, thereby driving the raising and lowering of the water-blocking plate. In this design, the thread pitch allows for precise adjustment of the water-blocking plate's movement speed and height, adapting to different water level requirements. The filtration device's projection on the horizontal plane is M-shaped. Compared to traditional planar filters (with a straight cross-section), the M-shaped structure increases the interception surface area in existing agricultural irrigation water-blocking devices, improving impurity interception efficiency. The M-shaped structure also disperses the water flow impact force, exhibiting strong impact resistance. Impurities flow along the water flow to both sides of the filtration device, preventing them from accumulating in the middle of the filter screen and delaying clogging.

[0018] This utility model features a handle on the top of the filter device. When it is observed that there are many impurities in the collection net, the handle can be lifted manually or with a crane to pull the filter device upwards. The groove is set in the vertical direction, and the filter device can then be pulled out of the groove. Impurities on the collection net can then be collected specifically, enabling convenient manual cleaning of impurities and reducing maintenance difficulty. The filter net is V-shaped, and the V-shaped bending design improves the filter net's resistance to deformation, making it especially suitable for irrigation water with high flow rates or containing large particles of impurities.

Detailed Implementation

[0026] Example

[0027] This embodiment provides an agricultural irrigation water retention device, such as... Figure 1-5 As shown, the device includes a water storage tank 1 and pre-installation columns 2. The water storage tank 1 serves as the main structure of the device, used to store irrigation water and perform core functions such as interception and water storage. By adjusting the internal water level, it provides a stable and periodic water supply for crop growth. A pre-installation groove is provided on the opposite side of the water storage tank 1. The pre-installation groove is a recessed structure located on the inner wall of both sides of the water storage tank 1, and the pre-installation column 2 is installed inside the pre-installation groove.

[0028] The pre-installation column 2 is a vertical support column inserted into the pre-installation slot. It serves as the mounting base for components such as the water-retaining plate 4 and the mounting frame 3, bearing the structural load and providing positioning. The mounting frame 3 is inserted into the pre-installation column 2. The mounting frame 3 is a metal frame inserted into the pre-installation column 2, serving as a sliding track to support the water-retaining plate 4. The water-retaining plate 4 is slidably connected inside the mounting frame 3. The water-retaining plate 4 controls the water storage volume by adjusting its height. When closed, it intercepts and stores water flow; when opened, it releases irrigation water as needed. A mounting platform 5 is fixedly installed on the top of the mounting frame 3. A lifting motor 6 is fixedly positioned at the center of the top of the mounting platform 5. Mounting holes are provided on both sides of the pre-installation slot. A fixing pin 7 is inserted into the mounting hole. The fixing pin 7 penetrates the interior of the pre-installation column 2 and the mounting frame 3, locking the pre-installation column 2 to maintain the overall stability of this application. After the fixing pin 7 is inserted, it locks the pre-installation column 2 and the mounting frame 3, preventing structural misalignment caused by vibration or water flow impact, ensuring the long-term stability of the device. The fixing pin 7 penetrates the interior of the pre-installation column 2 and the mounting frame 3. On the water-facing side, a groove 8 is recessed on the inner wall of the pre-installation column 2, into which the filter device 9 can be embedded.

[0029] The output end of the lifting motor 6 is threadedly connected to the screw 10. This threaded connection converts the rotational motion of the lifting motor 6 into the linear motion of the screw 10, thereby driving the baffle plate 4 to rise and fall. In this design, the thread pitch allows for precise adjustment of the baffle plate 4's moving speed and height, adapting to different water level requirements.

[0030] The bottom of the screw 10 is rotatably connected to the storage plate 4 (specifically, the screw 10 is connected to the inner ring of the bearing, while the outer ring of the bearing is fixedly connected to the storage plate 4). When the screw 10 rotates, the storage plate 4 only moves up and down without rotating with the screw 10, thus avoiding mechanical wear. The rotatable connection disperses the force on the storage plate 4, reduces local stress concentration, and extends its service life.

[0031] The projection of the filter device 9 onto the horizontal plane is M-shaped. Compared with the traditional planar filter screen (with a "I"-shaped cross-section), the M-shaped structure in existing agricultural irrigation interception devices can increase the interception surface area and improve the impurity interception efficiency. The M-shaped structure also disperses the water flow impact force, and impurities flow along the water flow to both sides of the filter device 9, avoiding the accumulation of impurities in a single area and delaying the clogging of the filter device 9.

[0032] The filtration device 9 includes a filter screen 91, a collection rack 92, and a storage net 93. The filter screen 91 is V-shaped, and the V-shaped bending design enhances the filter screen 91's resistance to deformation, making it particularly suitable for irrigation water with high flow rates or containing large particles of impurities. Both ends of the filter screen 91 are fixedly connected to the collection rack 92. Because the collection rack 92 is located on both sides of the filter screen 91, a large amount of impurities (leaves, hair, straw, etc.) accumulate inside the collection rack 92 during actual operation. Multiple storage nets 93 are horizontally arranged inside the collection rack 92, and the storage nets 93 are fixedly connected to the collection rack 92, thereby collecting the aforementioned impurities.

[0033] The top of the filter device 9 is equipped with a handle 12. When it is observed that there are many impurities in the collection net 93, the handle 12 is lifted manually or by a crane to pull the filter device 9 upwards. The groove 8 is set in the vertical direction, and then the filter device 9 is pulled out from the groove 8. Then the impurities on the collection net 93 can be collected.

[0034] Guide rods 13 are fixedly connected to both ends of the top of the water-blocking plate 4, and the tops of the guide rods 13 are slidably connected to the mounting platform 5.

[0035] The "pre-installation slot" in this application adopts the same "pre-installation slot" technical solution as in Chinese Patent CN202420584597.8.

[0036] The length, height, and curvature of the lines of the collection rack 92 and the storage net 93 in the attached diagram are for illustrative purposes only, and those skilled in the art can make adaptive adjustments according to actual usage.

[0037] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
