Description

A hydraulic driver for driving device of lifting type buried sprinkler

technical field

The utility model belongs to the structural field of water-saving irrigation accessories, in particular to a hydraulic driver used for a driving device of a lifting type buried sprinkler head.

Background technique

At present, nozzle technology is used in places with high water consumption such as urban green spaces and golf courses to meet water requirements. The structure of the existing nozzle products is relatively complicated, and its structure is that the filtered water rushes to the impeller composed of multiple airfoils located on one end surface at a certain angle, driving a main shaft to rotate, and the shaft has a A driving gear drives the nozzle to rotate after being decelerated by several stages of gear pairs to achieve the purpose of spraying. In this driving structure, due to too many gear pairs, it brings great difficulty to manufacture and assembly; especially the high speed of the driving gear, which requires high installation accuracy of each gear shaft and high manufacturing accuracy of each gear shaft hole; In particular, since the modulus of each gear is small, basically only 0.5, there are high requirements for gear manufacturing and assembly precision. Therefore, the manufacturing cost of the driving structure of this structure is high. And since the gears from the first stage to the nozzle are all hard-connected through the gear, when the water pressure changes, the rotational angular velocity of the nozzle head directly changes significantly with the fluctuation of the water pressure; The gear pair will cause some damage.

Therefore, it is of great value to develop a simple and practical driving structure.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a hydraulic driver with a simple structure for the driving device of the lifting buried sprinkler head.

In order to achieve the above purpose, the technical scheme adopted is as follows:

A hydraulic driver used for a driving device of a lift-type buried sprinkler head, the main body of which is a disc structure, the center of the disc is provided with a shaft hole, and an inlet hole is provided near the shaft hole.

The utility model is one of the parts of the driving device of the lifting type buried sprinkler. Its function is to generate rotation and finally drive the sprinkler to rotate and spray water. There is an inlet hole near the hole, which is connected with other rotating parts through the shaft hole, and is driven to rotate by other rotating parts. The parts connected with the nozzle rotate to realize the rotary spraying of the nozzle.

In the above technical solution, an outer ring is provided on one edge of the disk, and the outer ring is used so that the water flow entering through the inlet hole is bound by the outer ring when it rotates, so that it will not leak easily, and at the same time, the rotation of the water flow is increased.

One side of the disc is provided with swirl ribs. The barrier of the swirl rib facilitates the rotation of the water flow entering through the inlet hole.

Further, the swirl ribs protrude to a certain height, and their cross-sections are square, rectangular, or semicircular.

One end of the baseline of the swirl rib is connected to the outer ring, and the other end ends at the edge of the inlet hole and points to the center of the shaft hole.

The baseline of the swirl rib is a curve, and the curve is a section of arc, a section of ellipse, or a section of involute.

As another structure, the baseline of the swirl ribs may also be a straight line.

As a preferred solution, the utility model is composed of a shaft hole, several inlet holes, several evenly distributed swirl ribs, a base plate and an outer ring, the base plate is perpendicular to the shaft hole, the inlet holes are located on the base plate and The substrate is completely opened, the inlet hole is close to the shaft hole and parallel to the shaft hole, the outer ring is located on the outer edge of the substrate, and the swirl rib is located on the substrate.

The utility model has a simple structure, can be connected with other rotating parts through the shaft hole, and is driven to rotate by other rotating parts. Drive other driving parts to rotate, so as to finally drive the rotating water spray of the nozzle.
