Description

Technical Field

[0001] This utility model relates to the field of flood control and drainage regulation devices, and in particular to a continuous rainfall flood control and drainage regulation device for tomato growing areas. Background Technology

[0002] The continuous rainfall prevention and drainage regulation device for tomato growing areas is designed to address the problem of waterlogging in fields caused by continuous rainfall, which leads to oxygen deficiency and rot in tomato roots. It can directly act on the soil layer and drainage structure in the growing area to guide and regulate the drainage of waterlogged areas. It is suitable for long-term use in areas where tomatoes are planted in large areas, the terrain is relatively flat, or areas prone to waterlogging.

[0003] The existing system allows workers to manually adjust the opening of the drainage valve on the device or activate a preset automatic sensor switch when tomatoes are at different growth stages, such as seedling stage and fruiting stage. This connects the device to the pre-laid drainage ditch or seepage pipe network in the field, ensuring timely drainage of accumulated water during continuous rainfall. It is suitable for various tomato planting areas, such as open-field tomato plantations and the area around greenhouse tomato facilities.

[0004] Existing continuous rainfall flood control and drainage regulation devices in tomato growing areas mostly operate using motor drive. This design not only increases operating costs in terms of equipment procurement and daily energy consumption, but also results in complex motor structures. Once a malfunction occurs, the maintenance process is cumbersome and time-consuming, affecting the timeliness of drainage operations. Furthermore, if leaks occur inside the device or in the connected pipes during drainage, they cannot be automatically resolved, requiring workers to manually disassemble the device or dredge the pipes for cleaning, which is inconvenient and inefficient. Therefore, a new continuous rainfall flood control and drainage regulation device for tomato growing areas is proposed to solve the above problems. Utility Model Content

[0032] Reference Figures 2-4This utility model provides an embodiment of a continuous rainfall prevention and drainage regulation device for tomato planting areas, including a device shell 1. The device shell 1 serves as the main support structure of the device, used to accommodate and protect the internal components. An installation plate 9 is fixedly connected to its bottom outer wall. The installation plate 9 can fix and position the bottom components of the device, and at the same time provide an installation foundation for the drainage structure. A drainage outlet 10 is opened on its outer wall. The drainage outlet 10 is connected to the external drainage system and is used to discharge the filtered water in the device to the external drainage system. A rotating shaft 2 is rotatably connected to the inner wall of the installation plate 9.

[0033] Reference Figures 1-3 The rotating shaft 2 can be used as a power transmission component to drive the related structure to rotate. A scraper 6 is fixedly connected to its top outer wall. The scraper 6 can rotate synchronously with the rotating shaft 2 to clean impurities on the surface of the filter plate 4. The bottom outer wall of the scraper 6 is in contact with the top outer wall of the filter plate 4. A spiral blade 7 is fixedly connected to the outer wall of the rotating shaft 2. The spiral blade 7 can transport the accumulated water in the device downward by rotating, accelerating the drainage process. The outer wall of the spiral blade 7 is in contact with the inner wall of the device housing 1, and the bottom outer wall of the spiral blade 7 is in contact with the top outer wall of the mounting plate 9.

[0034] Reference Figures 1-3 The outer top wall of the device housing 1 is provided with an external threaded groove 12, which is used to cooperate with the internal threaded groove 11 of the filter ring 5 to achieve a detachable connection between the two. The inner top wall of the device housing 1 is fixedly connected with a filter plate 4. The filter plate 4 performs secondary filtration after the filter ring 5 to further intercept small impurities remaining in the water. The outer wall of the rotating shaft 2 is rotatably connected to the inner wall of the filter plate 4. The outer wall of the external threaded groove 12 is threadedly connected with the filter ring 5. The filter ring 5 first performs initial filtration on the water entering the device to prevent large impurities from entering the device. Its outer wall is provided with filter holes 8, which are the channels for water to enter the device and also perform the function of initial filtration. Several sets of filter holes 8 are arranged in a ring according to the central axis of the rotating shaft 2 to ensure that the water enters the device evenly.

[0035] Reference Figures 1-2 , Figure 5 The bottom inner wall of the filter ring 5 is provided with an internal thread groove 11. The internal thread groove 11 and the external thread groove 12 cooperate to realize the stable connection between the filter ring 5 and the device housing 1. The outer wall of the internal thread groove 11 is adapted to the outer wall of the external thread groove 12. The device housing 1 is threadedly connected to the filter ring 5 through the internal thread groove 11 and the external thread groove 12. The top outer wall of the filter ring 5 is fixedly connected with a top cover 3. The top cover 3 can prevent external debris from falling into the device and avoid contaminating the filter structure. An ultrasonic transmitter 13 is provided on its inner wall. The ultrasonic transmitter 13 is used to eliminate the foam generated by the water during the filtration process and prevent the foam from obstructing the water flow. The output end of the ultrasonic transmitter 13 faces the inside of the filter ring 5.

[0036] Working Principle: The top outer wall of the filter plate 4 of this flood control and drainage regulating device is flush with the ground, facilitating the natural flow of field water. The water first contacts the filter ring 5 and undergoes primary filtration through several sets of filter holes 8 arranged in a ring on its outer wall, preventing large impurities from entering the device. The output end of the ultrasonic transmitter 13 on the inner wall of the top cover 3 faces the inside of the filter ring 5, eliminating the foam generated when the water washes through the filter holes 8, thus preventing foam from obstructing the water flow. After primary filtration and defoaming, the water enters the device shell 1 and then flows through the filter plate 4 fixed to the top inner wall of the device shell 1. The filter plate 4 performs secondary filtration to intercept fine impurities. At the same time, the impact force generated by the water flow drives the spiral blade 7 to rotate. The outer wall of the spiral blade 7 is in contact with the inner wall of the device shell 1, and its bottom is in contact with the top of the mounting plate 9. During its rotation, it will... The rotating shaft 2 rotates synchronously and is rotatably connected to the inner wall of the mounting plate 9 and the inner wall of the filter plate 4. The scraper 6 fixed at the top of the rotating shaft 2 rotates with the rotating shaft 2, and the bottom of the scraper 6 is in contact with the top of the filter plate 4, which can continuously scrape off the impurities attached to the surface of the filter plate 4 and prevent the filter plate 4 from clogging. Finally, the water that has been filtered twice flows downward under the conveying action of the spiral blade 7 and is discharged through the drain outlet 10 opened on the outer wall of the mounting plate 9. The drain outlet 10 is connected to the external drainage system. After the water enters the external drainage system through the drain outlet 10, it is guided away from the planting area, thus completing the flood prevention and drainage operation of the tomato planting area. If the filter ring 5 needs to be replaced, the filter ring 5 can be directly rotated and disassembled for replacement by using the threaded connection structure between the external threaded groove 12 at the top of the device housing 1 and the internal threaded groove 11 at the bottom of the filter ring 5.
