Quantitative water storage device for rice planting

Abstract

This utility model discloses a quantitative water storage device for rice cultivation, belonging to the field of rice cultivation. It includes a water storage tank with a lid on top. An inlet pipe is fixedly connected to the top of the lid, and an outlet valve is located at the bottom of the tank. A quantitative water storage component for quantitative water storage is installed inside the inlet pipe. The device works by raising two floats based on water level, which in turn push a rack upwards. This rotation drives a ball valve, causing the connection port to rotate. The connection port is misaligned with the opening of the sealing block, preventing water from flowing further into the water storage tank and stopping water storage.

Description

Technical Field

[0001] This utility model relates to the field of rice cultivation, and more specifically, to a quantitative water storage device for rice cultivation. Background Technology

[0002] The growth of crops depends not only on regional conditions but also on the availability of water resources. A lack of water resources will affect the growth of crops. Therefore, when the weather is dry and crops are short of water, farmers need to irrigate the farmland in a timely manner. Water storage devices are usually located in low-lying and flat areas, such as beside the field ridges or near irrigation ditches, to facilitate the collection of rainwater or the introduction of irrigation water. Traditional rice cultivation commonly employs flood irrigation, leading to insufficient water resource utilization and easy loss of soil nutrients. Existing water storage devices suffer from two major technical drawbacks: First, water level control relies on manual observation, making precise quantitative control difficult. For example, Chinese patent CN222349621U describes a simple field water control device that, while using a scale to detect water levels, requires complex structures such as hydraulic cylinders, resulting in high costs and inconvenient maintenance. Second, they lack dynamic adjustment capabilities, failing to adapt to the varying water requirements of rice at different growth stages. Summary of the Invention

[0003] In view of the problems existing in the prior art, the purpose of this utility model is to provide a quantitative water storage device for rice planting.

[0004] To solve the above problems, the present invention adopts the following technical solution.

[0005] A quantitative water storage device for rice cultivation includes a water storage tank, a tank cover on the top of the water storage tank, an inlet pipe fixedly connected to the top of the tank cover, a quantitative water storage component for quantitative water storage inside the inlet pipe, an outlet valve at the bottom of the water storage tank, and an adjustment component for controlling the amount of water stored on the top of the tank cover.

[0006] The quantitative water storage component includes a sealing block fixed to the bottom of the inner surface of the water inlet pipe and a fixing plate fixed to the outer surface. A ball valve is rotatably installed inside the sealing block. A connection port is opened inside the ball valve. A rotating shaft is symmetrically fixed to the outer surface of the ball valve. A gear is fixedly connected to one side of the rotating shaft. A rack is slidably connected inside the fixing plate. A float plate is fixedly connected to the bottom of the rack.

[0007] Furthermore, a push rod is fixedly connected to the top of one side of the rack, the top of the push rod extends out of the interior of the box cover, and the push rod slides against the box cover.

[0008] Furthermore, a limiting block is fixedly connected to one side of the rack, and the limiting block is located above the fixing plate, and the gear and rack mesh with each other.

[0009] Furthermore, one side of the rotating shaft extends into the interior of the water inlet pipe, and the rotating shaft and the water inlet pipe are rotatably connected to each other.

[0010] Furthermore, a sealing ring is provided on the outer surface of the ball valve, and the connection port is located inside the sealing block for rotational adaptation.

[0011] Furthermore, the adjustment assembly includes an internally threaded plate fixed to the outer surface of the water inlet pipe and a scale fixed to the outer surface of the water inlet pipe facing the vertical surface, and a threaded rod is rotatably connected to the top of the tank cover.

[0012] Furthermore, the threaded rod penetrates the interior of the internally threaded plate, and the internally threaded plate is provided with internal threads. The threaded rod and the internally threaded plate are connected by threads.

[0013] Furthermore, the bottom of the scale extends into the interior of the water tank, and the scale slides and adapts to the tank cover.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This solution incorporates a quantitative water storage component, which introduces rainwater into the storage tank. The water level rises, causing two floats to push upwards. These floats then move a rack upwards, which in turn rotates a ball valve. The rotation of the ball valve causes the connection port to rotate, misaligning it with the sealing block opening. This prevents water from flowing further into the storage tank from the inlet pipe, thus stopping water storage. When the water level reaches a certain height, the inlet pipe automatically seals off, achieving quantitative water storage and preventing water overflow and waste when unattended. This effectively saves significant costs.

[0015] 2. This solution incorporates an adjustment mechanism. Under the action of the threaded rod, the threaded rod drives the internal threaded plate to move up and down. The internal threaded plate then drives the water inlet pipe to slide up and down inside the tank cover. The movement of the water inlet pipe causes the float plate to float up and down as a whole, thereby adjusting the water level in contact with the float plate and controlling the amount of water stored in the water tank. This allows for flexible adjustment of the water requirements of rice at different stages. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 3 A quantitative water storage device for rice cultivation includes a water storage tank 1, a tank cover 2 on the top of the water storage tank 1, an inlet pipe 3 fixedly connected to the top of the tank cover 2, an outlet valve at the bottom of the water storage tank 1, a quantitative water storage component 4 for quantitative water storage inside the inlet pipe 3, and an adjustment component 5 for controlling the amount of water stored on the top of the tank cover 2.

[0020] like Figure 2-3 As shown, the quantitative water storage component 4 includes a sealing block 47 fixed to the bottom of the inner surface of the water inlet pipe 3 and a fixing plate 44 fixed to the outer surface. A ball valve 49 is rotatably installed inside the sealing block 47. A connection port 48 is opened inside the ball valve 49. A rotating shaft 41 is symmetrically fixedly connected to the outer surface of the ball valve 49. A gear 42 is fixedly connected to one side of the rotating shaft 41. A rack 45 is slidably connected inside the fixing plate 44. A float plate 46 is fixedly connected to the bottom of the rack 45.

[0021] A push rod 43 is fixedly connected to the top of one side of the rack 45. The top of the push rod 43 extends out of the interior of the box cover 2, and the push rod 43 slides against the box cover 2.

[0022] A limiting block is fixedly connected to one side of the rack 45, and the limiting block is located above the fixing plate 44. The gear 42 and the rack 45 mesh with each other.

[0023] One side of the rotating shaft 41 extends into the interior of the water inlet pipe 3, and the rotating shaft 41 and the water inlet pipe 3 are rotatably connected to each other.

[0024] A sealing ring is provided on the outer surface of the ball valve 49, and the connection port 48 is located inside the sealing block 47 for rotational adaptation.

[0025] Water is connected to an external water inlet pipe via inlet pipe 3. Water flows into the water storage tank 1 through inlet pipe 3 and connection port 48. As time progresses, the water level rises continuously. When the water surface contacts the bottom of float plate 46, the water level causes the two float plates 46 to push upward. The float plates 46 push rack 45 upward, which drives gear 42 to rotate. Gear 42 drives ball valve 49 to rotate through shaft 41. The rotation of ball valve 49 drives connection port 48 to rotate. When connection port 48 rotates to a certain angle, connection port 48 and sealing block 47 are misaligned, preventing water from flowing into the water storage tank 1. This stops water storage in the water storage tank 1. When the water reaches a certain height, the inlet pipe 3 is automatically sealed, thus achieving quantitative water storage and preventing water overflow and waste when unattended, effectively saving a lot of costs. When using a water storage device, the outlet valve of the device needs to be connected to the irrigation pipe or drip irrigation tape, and the installation location should be close to the water pump or water source distribution node to shorten the water delivery distance, thereby reducing energy consumption.

[0026] When water is stored again, in order to ensure that water enters the inlet pipe 3 smoothly, the push rod 43 can be pushed down, which will drive the rack 45 to move down. When the rack 45 moves down, it will drive the gear 42 to reverse, which will drive the ball valve 49 to rotate in the opposite direction, so that the connection port 48 is in a vertical state. The limit block and the fixing plate 44 are in contact with each other, so that the rack 45 cannot continue to move down, thus ensuring that the connection port 48 reaches a vertical state.

[0027] like Figure 1 As shown, the adjustment assembly 5 includes an internally threaded plate 53 fixed to the outer surface of the water inlet pipe 3 and a scale 52 fixed to the outer surface of the water inlet pipe 3 facing the vertical surface. The top of the cover 2 is rotatably connected to a threaded rod 51.

[0028] The threaded rod 51 passes through the interior of the internal threaded plate 53, which has internal threads. The threaded rod 51 and the internal threaded plate 53 are connected by threads.

[0029] The bottom of the scale 52 extends into the interior of the water tank 1, and the scale 52 and the tank cover 2 slide against each other.

[0030] When the demand for rice varies at different stages, it is necessary to control the required water intake. At this time, rotating the threaded rod 51 causes the inner threaded plate 53 to move up and down under the action of the thread. The inner threaded plate 53 causes the water inlet pipe 3 to slide up and down inside the tank cover 2. The movement of the water inlet pipe 3 can cause the float plate 46 to move up and down as a whole, thereby adjusting the water level in contact with the float plate 46. This allows control over the amount of water stored in the water tank 1, thus flexibly adjusting the water demand of rice at different stages.

[0031] Usage: The water storage device is usually located in a low-lying and flat area, such as beside a field ridge or near an irrigation canal, to facilitate the collection of rainwater or the introduction of irrigation water. Rainwater and irrigation water are connected to the inlet pipe 3 via an external pipe. The rainwater and irrigation water flow into the water storage tank 1 through the inlet pipe 3 and the connection port 48. As time goes on, the water level rises continuously. When the water surface contacts the bottom of the float plate 46, the water level causes the two float plates 46 to push upward. The float plates 46 push the rack 45 upward, and the rack 45 drives the gear 42 to rotate. The gear 42 drives the shaft 41 to rotate... The ball valve 49 rotates, which drives the connection port 48 to rotate. When the connection port 48 rotates to a certain angle, the connection port 48 and the opening of the sealing block 47 are misaligned, so that the water flow inside the water inlet pipe 3 can no longer flow into the water storage tank 1, thereby stopping the water storage inside the water storage tank 1. When the water reaches a certain height, the inside of the water inlet pipe 3 can be automatically sealed, thereby achieving quantitative water storage and avoiding water overflow inside the water storage tank 1 when no one is watching, thus saving a lot of costs. When using a water storage device, the device's outlet valve must be connected to an irrigation pipe or drip irrigation tape, and the installation location should be close to a water pump or water source distribution node to shorten the water delivery distance, thereby reducing energy consumption. When the demand for rice varies at different stages, it is necessary to control the required water intake. At this time, rotating the threaded rod 51 causes the inner threaded plate 53 to move up and down under the action of the thread. The inner threaded plate 53 causes the water inlet pipe 3 to slide up and down inside the tank cover 2. The movement of the water inlet pipe 3 can cause the float plate 46 to move up and down as a whole, thereby adjusting the water level in contact with the float plate 46. This allows control over the amount of water stored in the water tank 1, thus flexibly adjusting the water demand of rice at different stages.

[0032] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
