Description

Technical Field

[0001] The utility model relates to the technical field of ecological irrigation sprinklers, in particular to a sprinkler head for ecological water-saving irrigation with adjustable flow. Background Art

[0002] Ecological irrigation sprinkler is a sprinkler specially designed for irrigation. Ecological irrigation sprinkler is mainly used in agricultural irrigation, garden irrigation, municipal greening irrigation, home gardening irrigation and other fields.

[0003] Ecological irrigation sprinklers are generally composed of a pipe joint, a nozzle, a bracket, and a refraction cone. The lower end of the pipe joint is connected to a booster water pump. Its specific use is that high-pressure water flows vertically upward through the pipe joint and the nozzle and is sprayed onto the inclined lower end surface of the refraction cone, thereby achieving the irrigation effect of high-pressure water scattering to the outside. In addition, a filter is preset in the pipe joint to ensure the cleanliness of the water quality.

[0004] At present, after long-term use, the existing ecological irrigation sprinklers will have particulate impurities accumulated on the upper end surface of the filter, causing the filter and the sprinkler to be blocked, which in turn causes the sprinkler to have a low water flow smoothness, resulting in water accumulation and inability to spray water normally, resulting in a waste of water resources. In addition, the high-pressure water flow is sprayed vertically upward through the sprinkler to the inclined lower end surface of the refraction cone. This long-term spraying will cause the inclined lower end surface of the refraction cone to wear or even penetrate, resulting in a waste of water resources, and further causing part of the sprayed water to be unable to be sprayed on the inclined lower end surface of the refraction cone to effectively achieve a scattered irrigation effect. The refraction cones are mostly directly welded and fixed, and the worn refraction cones cannot be easily disassembled and replaced.

[0005] The above-mentioned problems will greatly affect the flow adjustability and water-saving performance of ecological irrigation sprinklers. These problems are widespread and urgently need to be improved. Utility Model Content

[0006] The purpose of the utility model is to solve the above-mentioned shortcomings in the prior art and to propose a flow-adjustable ecological water-saving irrigation sprinkler.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A flow-adjustable ecological water-saving irrigation sprinkler is designed, comprising a sprinkler, a pipe joint connected below the sprinkler, a booster water pump connected at its lower end, a water supply pipe connected at its lower end, and a filter screen and a flow control valve provided on the pipe joint;

[0009] The outer wall of the nozzle is provided with a chassis, a controller is provided on the chassis, and a refraction cone is provided above the nozzle;

[0010] The chassis is provided with a support frame, the support frame is provided with a mounting seat strip, the mounting seat strip is provided with a locking slot, the refractive cone is provided with a reinforcement frame, the reinforcement frame is provided with a mounting frame, the mounting frame is provided with a locking screw, and the locking screw is provided with a handle.

[0011] Furthermore, the upper and lower ends of the booster water pump are respectively connected to the pipe joint and the water supply pipe, and the flow control valve is arranged on the pipe joint.

[0012] Furthermore, the chassis as a whole is a circular ring structure and is fixedly arranged along the outer wall surface of the nozzle, and the controller is arranged on the lower end surface of the chassis.

[0013] Furthermore, the support frame body is a bent structure as a whole and is symmetrical in two parts, and the mounting seat bar is arranged at the central part of the two support frames.

[0014] Furthermore, the locking screw and the locking slot form a group, which are two groups symmetrical in front and back. The locking screw is threadedly connected to the mounting frame and is engaged with the locking slot.

[0015] Furthermore, the side cross-section of the mounting frame is a U-shaped structure, and the mounting frame is snap-connected with the mounting seat bar.

[0016] Furthermore, the refractive cone is a cone-shaped structure as a whole and has a hollow cavity inside, and the reinforcement frame is a cross-shaped structure as a whole and is arranged at the top of the refractive cone.

[0017] The utility model proposes a flow-adjustable ecological water-saving irrigation sprinkler, which has the following beneficial effects:

[0018] 1. The utility model sets a flow control valve on the pipe joint and a chassis with a controller on the nozzle. When the filter holes of the filter screen accumulate too many particulate impurities and become clogged, resulting in a decrease in water flow, the flow control valve that has been monitoring the flow rate can give a signal to the controller. The PLC in the controller will control the booster pump to increase the pressure and increase the pumping pressure. The high-pressure water flow will push the particulate impurities blocked in the filter holes upward and spray them out through the nozzle, thereby greatly improving the flow adjustability of the ecological irrigation nozzle.

[0019] 2. The utility model has a detachable refraction cone structure. If the refraction cone is damaged or has holes, the refraction cone can be easily disassembled and replaced, avoiding the situation where part of the water flows through the damaged hole on the refraction cone and the scattered irrigation effect cannot be achieved, causing water waste, thereby improving the water-saving performance of ecological irrigation.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Reference Figure 1-6 A flow-adjustable ecological water-saving irrigation sprinkler comprises a sprinkler 1, a pipe joint 2 is connected to the bottom of the sprinkler 1, a booster water pump 3 is connected to the lower end of the pipe joint 2, a water supply pipe 31 is connected to the lower end of the booster water pump 3, and a filter 22 and a flow control valve 21 are provided on the pipe joint 2;

[0029] The outer wall of the nozzle 1 is provided with a chassis 11, and the chassis 11 is provided with a controller 12. A refraction cone 5 is provided above the nozzle 1, and the refraction cone 5 is a prior art;

[0030] The chassis 11 is provided with a support frame 4, the support frame 4 is provided with a mounting seat strip 41, the mounting seat strip 41 is provided with a locking slot 42, the refractive cone 5 is provided with a reinforcement frame 51, the reinforcement frame 51 is provided with a mounting frame 52, the mounting frame 52 is provided with a locking screw 6, and the locking screw 6 is provided with a grip handle 61.

[0031] The upper and lower ends of the booster water pump 3 are respectively connected to the pipe joint 2 and the water supply pipe 31. The flow control valve 21 is arranged on the pipe joint 2. The flow control valve 21 can monitor the water flow in the pipe joint 2 in real time and send the flow signal to the PLC in the controller 12 in real time to realize real-time monitoring and timely adjustment of the flow. A flow preset value is provided on the flow control valve 21, which is the water flow value when the mesh of the filter screen 22 is not blocked.

[0032] The chassis 11 is a circular ring structure as a whole and is fixedly arranged along the outer wall of the nozzle 1. The controller 12 is arranged on the lower end surface of the chassis 11. A PLC is preset in the controller 12, which can effectively control the pumping pressure of the booster water pump 3 in real time.

[0033] The support frame 4 is a whole bent structure and is symmetrical on the left and right. The mounting seat strip 41 is arranged in the central part of the two support frames 4, ensuring that the water flow sprayed upward from the lower nozzle 1 can be accurately sprayed on the lower tip of the refraction cone 5, thereby achieving a scattered irrigation effect.

[0034] The locking screw 6 and the locking slot 42 form a group, which are two groups symmetrical in front and back. The locking screw 6 is threadedly connected to the mounting frame 52 and is engaged with the locking slot 42. The handle 61 is a diamond-shaped structure as a whole and can be directly turned by hand without the use of tools such as screwdrivers. It is very convenient to disassemble and assemble.

[0035] The side cross-section of the mounting frame 52 is a U-shaped structure, and the mounting frame 52 is snap-fitted to the mounting seat bar 41 to ensure the stability of the snap-fitting installation of the mounting frame 52 and the mounting seat bar 41 .

[0036] The refractive cone 5 is a cone-shaped structure with a hollow cavity inside. The reinforcement frame 51 is a cross-shaped structure and is arranged at the top of the refractive cone 5. It not only improves the overall structural stability of the refractive cone 5, prevents deformation, and ensures the scattered irrigation effect, but also improves the lightweight of the refractive cone 5.

[0037] Working mode: After long-term use, when the filter holes of the filter screen 22 accumulate too many particulate impurities and become clogged, resulting in a decrease in water flow, the flow control valve 21 that has been monitoring the flow can give a signal to the controller 12, and the PLC in the controller 12 will control the booster pump 3 to increase the pressure and increase the pumping pressure. The high-pressure water flow will enter the pipe joint 2 through the water supply pipe 31, and then push the particulate impurities in the filter holes of the filter screen 22 in the nozzle 1 upward, and then the particulate impurities will pass through the top opening of the nozzle 1 and be sprayed to the outside. Then the PLC in the controller 12 will control the booster pump 3 to restore the previous water flow suction force, ensuring the smooth flow of water in the filter holes of the filter screen 22, and greatly improving the overall flow adjustability of the ecological irrigation nozzle 1.

[0038] In addition, after long-term use, if the refractive cone 5 is damaged or has holes, part of the flow will pass through the damaged holes on the refractive cone 5 and the scattered irrigation effect cannot be achieved, thereby causing a waste of water. At this time, first turn off the booster pump 3, then hold the refractive cone 5 with one hand, and hold the turning handle 61 counterclockwise with the other hand to drive the locking screw 6 to rotate counterclockwise, and drive the locking screw 6 to move outward through the threaded transmission between the mounting bracket 52. After the locking screw 6 exits the locking slot 42, stop rotating the turning handle 61, and then move the refractive cone 5 downward. After the mounting bracket 52 is separated from the mounting seat strip 41, it can be easily removed. Later, the new refractive cone 5 can be quickly installed on the mounting seat strip 41, thereby improving the water-saving performance of ecological irrigation.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
