Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to an irrigation device for water conservancy projects. Background Technology

[0002] Water conservancy projects are applied in various fields, including crop irrigation. During the growth of crops, irrigation devices are needed to supplement water and make up for the lack of natural rainfall in order to ensure crop growth.

[0003] A search revealed a Chinese patent application with patent number CN202421324546.8, which discloses an irrigation device for water conservancy projects. The device features adjustable nozzles for easy adjustment of the height and direction of the nozzles to irrigate crops, rotatable nozzles for easy adjustment of the spray angle to ensure even spraying, and nozzles that are easy to disassemble and assemble quickly for easy replacement and maintenance.

[0004] However, since the above technical solution does not have a mechanism to drive the nozzle to rotate continuously, the nozzle can usually only irrigate the side facing the nozzle when it is spraying water, and cannot continuously irrigate a large area around the nozzle, resulting in a low irrigation area of ​​a single nozzle. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an irrigation device for water conservancy projects.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An irrigation device for water conservancy projects includes a main mounting frame and an auxiliary mounting frame. Irrigation pipes are installed on the inner walls of the main and auxiliary mounting frames. Connecting bearings are respectively installed on the top outer walls of the main and auxiliary mounting frames. Water guide pipes are rotatably connected to the inner walls of the connecting bearings. A nozzle is inserted into one end of the water guide pipe. Multiple spray pipes are inserted into the outer wall of the irrigation pipe. A connecting cover is fixed to the bottom end of the water guide pipe and is slidably connected to the top end of the spray pipe. A first gear ring is fixed to the outer wall of the water guide pipe. A servo motor is fixed to the outer wall of the main mounting frame. The output shaft of the servo motor passes through the top outer wall of the main mounting frame. A rotating shaft is rotatably connected to the top outer wall of the auxiliary mounting frame. A second gear ring is fixed to the rotating shaft and the output shaft of the servo motor, respectively. The second gear rings are meshed with the first gear ring.

[0008] As a further embodiment of this utility model: a set of transmission wheels is fixed to the outer wall of the rotating shaft and the output shaft of the servo motor, and a transmission belt is connected to the outer wall of the transmission wheels.

[0009] As a further improvement of this utility model: the outer walls of the main mounting frame and the auxiliary mounting frame are respectively fixed with support seats, and the irrigation pipe is set on the outer wall of the support seat.

[0010] As a further improvement of this utility model: the outer walls of the main mounting frame and the auxiliary mounting frame are respectively fixed with shields, and the water guide pipe passes through the top outer wall of the shield.

[0011] As a further improvement of this utility model, a shielding frame is fixed to one side of the outer wall of the shielding cover.

[0012] As a further improvement of this utility model: multiple fixing rods are fixed to the top outer wall of the shield, and an annular guide rail is fixed to the top outer wall of the fixing rods.

[0013] As a further improvement of this utility model: the outer wall of the nozzle is rotatably connected to a guide roller, and the outer wall of the guide roller is rolled on the inner wall of the annular guide rail.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. When the servo motor is running, it drives the rotating shafts on multiple auxiliary mounting brackets on the outer wall of the irrigation pipe to rotate through the transmission wheel and transmission belt. This simultaneously drives multiple second gear rings to rotate. When the second gear rings rotate, they drive multiple water guide pipes on the outer wall of the irrigation pipe to rotate under the guidance of the connecting bearing through the meshing first gear ring. This causes the nozzles at one end of the water guide pipes to rotate continuously, allowing the nozzles to spray water onto the area around the irrigation pipe, thereby increasing the irrigation area of ​​the irrigation device.

[0016] 2. The rotating shafts on the top of the other auxiliary mounting brackets on the outer wall of the irrigation pipe can be connected by transmission belts and transmission wheels, so that the servo motor on the outer wall of the main mounting bracket can drive the multiple rotating shafts to rotate synchronously, making this irrigation device suitable for irrigation pipes of different lengths.

[0017] 3. When the entire nozzle rotates under the drive of the water guide pipe, the guide roller at the bottom also rolls on the inner wall of the annular guide rail. Thus, the guide roller and the annular guide rail support and guide the entire nozzle as it rotates with the water guide pipe, improving the stability of the nozzle when spraying water.

Detailed Implementation

[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0025] Example 1: An irrigation device for water conservancy projects, such as... Figure 1-4 As shown, the system includes a main mounting frame 1 and an auxiliary mounting frame 2. Irrigation pipes 6 are provided on the inner walls of the main mounting frame 1 and the auxiliary mounting frame 2. Connecting bearings 14 are respectively provided on the top outer walls of the main mounting frame 1 and the auxiliary mounting frame 2. A water guide pipe 4 is rotatably connected to the inner wall of the connecting bearing 14. A nozzle 5 is inserted into one end of the water guide pipe 4. Multiple spray pipes 3 are inserted into the outer wall of the irrigation pipe 6. A connecting cover 13 is fixed to the bottom end of the water guide pipe 4. The connecting cover 13 is slidably connected to the top end of the spray pipe 3. A first gear ring 15 is fixed to the outer wall of the water guide pipe 4. A servo motor 8 is fixed to the outer wall of the main mounting frame 1. The output shaft of the servo motor 8 passes through the top outer wall of the main mounting frame 1. A rotating shaft 20 is rotatably connected to the top outer wall of the auxiliary mounting frame 2. A second gear ring 16 is fixed to the rotating shaft 20 and the output shaft of the servo motor 8, respectively. The second gear ring 16 is meshed with the first gear ring 15.

[0026] A set of transmission wheels 18 are fixed to the outer walls of the rotating shaft 20 and the output shaft of the servo motor 8, and a transmission belt 17 is connected to the outer wall of the transmission wheels 18.

[0027] In this embodiment, one end of the irrigation pipe 6 is connected to a water pump. The water pump fills the irrigation pipe 6 with water from the corresponding reservoir or river ditch. Then, the water flows through the nozzle 3 into the water guide pipe 4 located at the top, and then sprays out through the nozzle 5 at one end of the water guide pipe 4.

[0028] The operator can control the servo motor 8 to run. When the servo motor 8 is running, it can drive the rotating shaft 20 on the multiple auxiliary mounting brackets 2 on the outer wall of the irrigation pipe 6 to rotate through the transmission wheel 18 and the transmission belt 17. This will simultaneously drive the multiple second gear rings 16 to rotate. When the second gear rings 16 rotate, they will drive the multiple water guide pipes 4 on the outer wall of the irrigation pipe 6 to rotate under the guidance of the connecting bearing 14 through the first gear ring 15 that meshes with them. This will drive the nozzle 5 at one end of the water guide pipe 4 to rotate continuously, so that the nozzle 5 can spray the area around the irrigation pipe 6 and increase the irrigation area of ​​the irrigation device.

[0029] In this embodiment, the rotating shafts 20 on the top of the other auxiliary mounting brackets 2 on the outer wall of the irrigation pipe 6 can be connected by a transmission belt 17 and a transmission wheel 18, so that the servo motor 8 on the outer wall of the main mounting bracket 1 can drive the multiple rotating shafts 20 to rotate synchronously, so that this irrigation device can be used for irrigation pipes 6 of different lengths.

[0030] like Figure 1-2 As shown, the main mounting frame 1 and the auxiliary mounting frame 2 are respectively fixed with support seats 7 on their outer walls, and the irrigation pipe 6 is set on the outer wall of the support seat 7; the support seat 7 can provide stable support for the irrigation pipe 6 as a whole, thereby improving the overall stability of the irrigation pipe 6.

[0031] like Figure 2 As shown, the outer walls of the main mounting frame 1 and the auxiliary mounting frame 2 are respectively fixed with shields 9, and the water guide pipe 4 passes through the top outer wall of the shield 9; the shield 9 can shield and protect the first toothed ring 15, the second toothed ring 16 and the rotating shaft 20 on the top of the main mounting frame 1 and the auxiliary mounting frame 2, thereby improving the overall service life of the irrigation device.

[0032] like Figure 1-2 As shown, a shielding frame 12 is fixed to one side of the outer wall of the shielding cover 9; the shielding frame 12 can shield and protect the transmission belt 17 connected between the main mounting frame 1 and the auxiliary mounting frame 2, thereby improving the service life of the transmission belt 17.

[0033] In this embodiment, the servo motor 8 can be directly connected to the mains power or generator and other power generation equipment via a line for power supply.

[0034] Working principle: One end of the irrigation pipe 6 is connected to a water pump. The water pump fills the irrigation pipe 6 with water from the corresponding reservoir or river ditch. Then, the water flows through the nozzle 3 and sprays into the water guide pipe 4 located at the top. Then, the servo motor 8 is controlled to run. When the servo motor 8 runs, it drives the rotating shaft 20 on the multiple auxiliary mounting brackets 2 on the outer wall of the irrigation pipe 6 to rotate through the transmission wheel 18 and the transmission belt 17. This drives multiple second gear rings 16 to rotate at the same time. When the second gear rings 16 rotate, they drive the multiple water guide pipes 4 on the outer wall of the irrigation pipe 6 to rotate under the guidance of the connecting bearing 14 through the meshing first gear ring 15. This drives the nozzle 5 at one end of the water guide pipe 4 to rotate continuously, so that the nozzle 5 can spray the area around the irrigation pipe 6.

[0035] Example 2: An irrigation device for water conservancy projects, such as... Figure 2 As shown, this embodiment makes the following improvements based on embodiment 1: multiple fixing rods 10 are fixed to the top outer wall of the shield 9, and an annular guide rail 11 is fixed to the top outer wall of the fixing rods 10; a guide roller 19 is rotatably connected to the outer wall of the nozzle 5, and the outer wall of the guide roller 19 is rolled on the inner wall of the annular guide rail 11; when the nozzle 5 rotates under the drive of the water guide pipe 4, the guide roller 19 at the bottom will also roll on the inner wall of the annular guide rail 11, thereby supporting and guiding the nozzle 5 as it rotates with the water guide pipe 4 through the guide roller 19 and the annular guide rail 11, improving the stability of the nozzle 5 when spraying water.

[0036] Working principle: When the nozzle 5 rotates under the drive of the water guide pipe 4, the guide roller 19 at the bottom will also roll on the inner wall of the annular guide rail 11. Thus, the guide roller 19 and the annular guide rail 11 support and guide the nozzle 5 as it rotates with the water guide pipe 4.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
