Description

Technical Field

[0001] The utility model relates to the technical field of irrigation, in particular to a buried telescopic sprinkler irrigation device. Background Art

[0002] The buried telescopic sprinkler irrigation device is a new type of farmland irrigation device that realizes automatic telescoping by water power drive. It is fixedly buried below the tillage layer. When in use, the sprinkler head automatically extends from the ground under the action of water pressure, and automatically retracts into the ground through the siphon principle after irrigation.

[0003] The prior art application No. 201310006949.8 discloses a buried automatic telescopic integrated sprinkler irrigation device, which is connected to a water conveyance pipeline. Its characteristics are as follows: the sprinkler irrigation device includes a sleeve, a first-stage telescopic pipe, and a second-stage telescopic pipe that are sequentially sleeved from outside to inside, as well as a lifting sprinkler head, a bypass branch pipe, and a spring; the sleeve is buried under the ground, and the sleeve is connected to the water conveyance pipeline. The first-stage telescopic pipe is connected to the sleeve, and the first-stage telescopic pipe can slide up and down relative to the sleeve wall... All components of the sprinkler irrigation device are buried 0.35 m underground. The sprinkler irrigation device further includes a drain valve, and the drain valve is arranged at the end of the water conveyance pipeline. By setting the bypass branch pipe, it is ensured that its multi-stage telescopic pipe can completely fall back, and the water in the sprinkler irrigation device is discharged through the drain valve.

[0004] However, there are some problems in the above technical solution: the drain valve is arranged at the end of the water conveyance pipeline. The water between the telescopic pipe and the sleeve is discharged through the drain valve, but the water in the sprinkler irrigation device in the low-lying area is difficult to discharge, and the water input into the sprinkler irrigation device flows back to the water source, resulting in waste of energy; the connection part between the bypass branch pipe and the sleeve is located above the bottom of the first-stage telescopic pipe, which reduces the water flow pressure difference, reduces the descending efficiency of the telescopic pipe, and after the retractable pipe has completely fallen back, the water input into the sleeve through the bypass branch pipe is difficult to discharge, and the water stored for a long time will affect the service life of the irrigation device. Summary of the Utility Model

[0005] In view of the deficiencies of the prior art, the utility model provides a buried telescopic sprinkler irrigation device, which controls the movement of piston II through the movement of piston I, and controls the water pressure change in the shell through the water inlet and outlet of the shell, so as to control the lifting of the telescopic pipe. The structure is simple, fast, convenient, safe and reliable.

[0006] The present utility model is realized through the following technical solutions. There is provided a buried telescopic sprinkler irrigation device, which includes a housing. The housing is of a cavity structure. Inside the housing, there is a telescopic pipe that slides in the vertical direction. A through hole adapted to the telescopic pipe is opened at the top of the housing. The top of the telescopic pipe passes through the through hole and is provided with a nozzle; the housing is communicated with a water supply branch pipe. A piston I adapted to the water supply branch pipe is provided at the connection part of the water supply branch pipe and the housing, and the piston I is connected with a reset mechanism; an outlet is opened on the housing, and a piston II adapted to the outlet is provided at the outlet. The piston II is connected with the piston I through a transmission mechanism.

[0007] The present utility model controls the movement of the piston II through the movement of the piston I, and controls the change of the water pressure inside the housing through the water inlet and outlet of the housing, so as to control the lifting of the telescopic pipe; the water in the water supply branch pipe pushes the piston I to move towards the inside of the housing, and drives the piston II to move towards the outlet through the transmission mechanism. The water supply branch pipe is communicated with the housing and the outlet is closed. The water in the water supply branch pipe enters the housing, and the water pressure inside the housing gradually increases. The telescopic pipe gradually rises under the action of the water pressure; after the water supply branch pipe stops supplying water to the housing, the reset mechanism drives the piston I to move towards the water supply branch pipe, and drives the piston II to move towards the inside of the housing through the transmission mechanism. The outlet is communicated with the housing and the water supply branch pipe is closed. The water inside the housing is discharged through the outlet, and the water pressure inside the housing gradually decreases. The telescopic pipe gradually descends under the action of gravity and atmospheric pressure; the outlet can be arranged at the lower end of the housing to completely discharge the water in the sprinkler irrigation device.

[0008] As an optimization, the piston I slides through the water supply branch pipe, and a groove I is opened on the side of the piston I away from the housing. A water supply hole communicating with the outside of the piston I is opened on the inner side surface of the groove I; the piston II slides through the outlet, and a groove II is opened on the side of the piston II away from the housing. A water discharge hole communicating with the outside of the piston II is opened on the inner side surface of the groove II; it guides the movement direction of the piston I to prevent the piston I from completely detaching from the water supply branch pipe, resulting in the piston I being unable to close the water supply branch pipe; it guides the movement direction of the piston II to prevent the piston II from completely detaching from the outlet, resulting in the piston II being unable to close the outlet.

[0009] As an optimization, the extending direction of the water supply branch pipe is the same as the orientation of the outlet; the transmission mechanism includes a connecting rod extending along the extending direction of the water supply branch pipe. The two ends of the connecting rod are respectively connected to the piston I and the piston II; it simplifies the transmission structure and ensures the stability of the transmission.

[0010] As an optimization, the reset mechanism includes a spring extending along the extending direction of the water supply branch pipe. The two ends of the spring are respectively connected to the housing and the piston I. One end of the connecting rod passes through the spring and is connected to the piston I; the spring is used to reset the piston I, and the connecting rod is used to prevent the spring from deflecting, resulting in the failure of the piston I to be reset.

[0011] As an optimization, a water outlet pipe is connected to the water outlet, and a one-way check valve with an opening facing away from one end of the housing is provided on the water outlet pipe; the one-way check valve prevents the water in the soil from flowing back into the housing.

[0012] As an optimization, a filtering device is provided on the water outlet pipe, and the filtering device is located on the side where the opening of the one-way check valve faces; the filtering device prevents impurities in the water from entering the sprinkler irrigation equipment.

[0013] The beneficial effects of the present utility model are as follows: The present utility model controls the movement of piston II through the movement of piston I, and controls the change of water pressure in the housing through the water inlet and outlet of the housing, thereby controlling the lifting of the telescopic pipe; the water outlet can be arranged at the bottom of the housing to completely discharge the water in the sprinkler irrigation equipment; the water in the sprinkler irrigation equipment flows into the soil for irrigation, avoiding flowing back to the water source and causing waste of energy; the water in the housing is discharged through the water outlet, gradually reducing the internal pressure of the housing, so that the telescopic pipe automatically retracts into the housing under the action of its own gravity and pressure, reducing energy consumption and resource waste.

[0019] As Figure 1 and Figure 2 shown, the underground telescopic sprinkler irrigation equipment of the present utility model includes a housing 3. The housing 3 is of a cavity structure. A telescopic pipe 4 that slides in the vertical direction is provided inside the housing 3. A through hole adapted to the telescopic pipe 4 is opened at the top of the housing 3.

[0020] The housing 3 is connected to a water supply pipe 1 through a water supply branch pipe 2. The water in the water supply pipe 1 enters the water supply branch pipe 2 and pushes the piston I 6 to move towards the inside of the housing 3. The water in the water supply branch pipe 2 enters the housing 3, and the water pressure in the housing 3 gradually increases. The telescopic pipe 4 gradually rises under the action of the water pressure until the nozzle 5 reaches the predetermined position. The nozzle 5 rotates, and the water in the sprinkler irrigation device sprays the soil through the nozzle 5; after the water supply pipe 1 stops supplying water to the water supply branch pipe 2, the water pressure in the water supply branch pipe 2 gradually decreases. The reset mechanism 7 drives the piston I 6 to move towards the water supply branch pipe 2, and drives the piston II 10 to move towards the inside of the housing 3 through the transmission mechanism 8. The water outlet 9 is connected to the housing 3 and the water supply branch pipe 2 is closed. The water in the housing 3 is discharged through the water outlet 9, and the water pressure in the housing 3 gradually decreases. The telescopic pipe 4 gradually descends under the action of gravity and atmospheric pressure; the water outlet 9 is arranged at the lower end of the housing 3 to completely discharge the water in the sprinkler irrigation device.

[0021] As Figure 1 and Figure 2 shown, the piston I 6 slides through the water supply branch pipe 2, and a groove I is provided on the side of the piston I 6 away from the housing 3. A water supply hole communicating with the outside of the piston I 6 is provided on the inner side surface of the groove I; the piston II 10 slides through the water outlet 9, and a groove II is provided on the side of the piston II 10 away from the housing 3. A water discharge hole communicating with the outside of the piston II 10 is provided on the inner side surface of the groove II; the water pressure in the water supply branch pipe 2 gradually increases and pushes the piston I 6 to slide towards the inside of the housing 3 in the water supply branch pipe 2 until the water supply branch pipe 2 communicates with the housing 3 through the water supply hole. At the same time, the piston I 6 is transmitted through the transmission mechanism 8, and the piston II 10 slides towards the water outlet 9 and closes the water outlet 9; after the water supply branch pipe 2 stops supplying water to the housing 3, the reset mechanism 7 drives the piston I 6 to slide towards the water supply branch pipe 2, the water supply hole enters the water supply branch pipe 2, the piston I 6 closes the water supply branch pipe 2, and at the same time, the piston I 6 is transmitted through the transmission mechanism 8, and the piston II 10 slides towards the inside of the housing 3, and the water outlet 9 communicates with the inner cavity of the housing 3.

[0022] As Figure 1 and Figure 2 shown, the extending direction of the water supply branch pipe 2 is the same as the orientation of the water outlet 9; the transmission mechanism 8 includes a connecting rod extending along the extending direction of the water supply branch pipe 2, and the two ends of the connecting rod are respectively connected to the piston I 6 and the piston II 10; the axes of the water supply branch pipe 2, the water outlet 9 and the connecting rod are the same, and the transmission mechanism 8 further includes a sliding cylinder, and the connecting rod slides through the sliding cylinder; the water in the water supply branch pipe 2 pushes the piston I 6 to slide towards the inside of the housing 3 in the water supply branch pipe 2, and the piston I 6 drives the piston II 10 to slide towards the water outlet 9 through the connecting rod; after the water supply branch pipe 2 stops supplying water to the housing 3, the reset mechanism 7 drives the piston I 6 to slide towards the water supply branch pipe 2, and the piston I 6 drives the piston II 10 to slide towards the inside of the housing 3 through the connecting rod.

[0023] As Figure 1 andFigure 2 The reset mechanism 7 shown includes a spring extending along the extension direction of the water supply branch pipe 2. The two ends of the spring are respectively connected to the housing 3 and the piston I 6. One end of the connecting rod passes through the spring and is connected to the piston I 6. After the water supply branch pipe 2 stops supplying water to the housing 3, the spring drives the piston I 6 to slide towards the water supply branch pipe 2.

[0024] As Figure 1 and Figure 2 shown, the water outlet 9 communicates with a water outlet pipe 11. A one-way check valve 12 with an opening facing away from one end of the housing 3 is provided on the water outlet pipe 11. The water in the sprinkler irrigation device enters the soil through the one-way check valve 12 and prevents the water in the soil from flowing back into the sprinkler irrigation device.

[0025] As Figure 1 and Figure 2 shown, a filtering device 13 is provided on the water outlet pipe 11. The filtering device 13 is located on the side where the opening of the one-way check valve 12 faces. The filtering device 13 filters out impurities in the water to prevent the impurities from entering the sprinkler irrigation device along with the water flow.

[0026] In the actual production process, the water supply pipe 1 supplies water into the water supply branch pipe 2. The water pressure in the water supply branch pipe 2 gradually increases and pushes the piston I 6 to slide towards the inside of the housing 3 in the water supply branch pipe 2 until the water supply branch pipe 2 communicates with the housing 3 through the water supply hole. At the same time, the piston I 6 drives the piston II 10 to slide towards the water outlet 9 through the connecting rod and closes the water outlet 9. The water in the water supply branch pipe 2 enters the housing 3 through the water supply hole. The water pressure in the housing 3 gradually increases, and the telescopic pipe 4 gradually rises under the action of the water pressure until the nozzle 5 reaches the predetermined position. The nozzle 5 rotates, and the water in the sprinkler irrigation device is sprayed on the soil through the nozzle 5. After the sprinkler irrigation work is completed, after the water supply pipe 1 stops supplying water to the water supply branch pipe 2, the water pressure in the water supply branch pipe 2 gradually decreases. The spring drives the piston I 6 to move towards the water supply branch pipe 2, and the water supply hole enters the water supply branch pipe 2. The piston I 6 drives the piston II 10 to move towards the inside of the housing 3 through the connecting rod, and the water outlet 9 communicates with the housing 3. Under the action of gravity, the water in the housing 3 sequentially passes through the water outlet 9, the one-way check valve 12, and the filtering device 13 and then enters the soil. The water pressure in the housing 3 gradually decreases, and the telescopic pipe 4 gradually descends under the action of gravity and atmospheric pressure.
