Description

All-round automatic spray system in greenbelt

Technical Field

The utility model relates to a spray set field, in particular to all-round automatic spray system in greenbelt.

Background

With the continuous improvement of the infrastructure in China, the road bypass is often matched with a perfect green belt nowadays, so that a sidewalk, a bicycle lane, an auxiliary lane, a main lane and the like are separated. Because the area of afforestation is very big, if use the manpower to water its operation will be very wasted time and energy, consequently can set up automatic spray set in the greenbelt usually, regularly spray the greenbelt every day to use manpower cost sparingly.

However, since the green belts are installed along the roads and have a long length, water pipes for supplying water to the automated spraying devices are generally installed along the green belts. Because the spray heads of the automatic spraying device are arranged on the water supply pipe at intervals, the water pressure of the water supply pipe can be reduced along with the water flow flowing through the spray heads. When the water pressure of the water supply pipe is not enough to enable all the spray heads to work normally, the spray heads arranged at the tail ends of the water supply pipe are not enough to drive water flow to spray due to too low water pressure, and the water flow can only slowly flow out of the spray heads, so that waste is caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an all-round automatic sprinkler system of greenbelt, it has self-closing when low water pressure, opens the advantage with the using water wisely automatically when high water pressure.

The above technical purpose of the present invention can be achieved by the following technical solutions:

the utility model provides an all-round automatic spray system in greenbelt, includes raceway and interval setting in the shower nozzle on the raceway, the shower nozzle is including installing the water distributor on the raceway and installing the cap that spouts on the water distributor, spout the cap including install outer cap on the water distributor and the cover locate outer cap in and with the outer cap inner cap that slides and be connected, be provided with the elastic component that compresses tightly inner cap on the water distributor between inner cap and the outer cap, set up the inner cap through-hole on the lateral wall of inner cap, be provided with outer cap through-hole on the lateral wall of outer cap, the elastic component compression or diastole are counterpointed or are staggered with outer cap through-hole of control and inner cap through-hole.

Through adopting above-mentioned technical scheme, when the pressure of water in the interior cap to interior cap bottom was greater than the pressure of pressure spring to interior cap bottom, interior cap compression pressure spring and along the inner wall of outer cap slide, until outer cap through-hole and interior cap through-hole mutual counterpoint, rivers outwards spout through interior cap through-hole and outer cap through-hole this moment, the shower nozzle begins the operation of spraying. When the pressure of the water in the inner cap to the bottom of the inner cap is smaller than the pressure of the pressure spring to the bottom of the inner cap, the inner cap is pressed on the water distribution pipe by the pressure spring, the outer cap through hole and the inner cap through hole are staggered, the water in the spray head cannot be sprayed out, the phenomenon that the water pressure in the pipe cannot play a role of spraying when low-pressure water flows out of the spray head is avoided, the waste of water resources is avoided, and a good water saving effect is achieved.

In addition, when the water pressure in the spray head is higher, the distance of the water column sprayed out from the spray head is farther, and the spraying effect is better. The spray head in the system can be opened only by high water pressure, and the spraying effect is good.

Through adopting above-mentioned technical scheme, rivers flow along the runner of water conservancy diversion post after getting into the inner cap, and the runner plays the guide effect to rivers, avoids rivers to take place the turbulent flow in the inner cap and leads to rivers velocity of flow to reduce. Since the water flow per unit time through the cross sections of the flow channels is equal, and the flow channels become shallower in the direction away from the water distribution pipes, that is, the cross sections of the flow channels become smaller, the flow velocity of the water passing through the cross sections increases. Rivers accelerate gradually when moving along the runner, have higher jet velocity when finally following the shower nozzle blowout for it is bigger to spray the area, and the effect is better.

Further setting: the inner cap through hole is communicated with the tail end of the flow channel, the opening direction of the inner cap through hole is the same as the tangential direction of the tail end of the flow channel, and the opening direction of the outer cap through hole is the same as the opening direction of the inner cap through hole.

Through adopting above-mentioned technical scheme, the velocity direction of rivers is the tangential direction of its place runner, and outer cap through-hole and interior cap through-hole follow the terminal tangential direction setting of runner, from outer cap through-hole and interior cap through-hole blowout when rivers move the runner end, can not receive the hindrance of outer cap through-hole and interior cap through-hole inner wall for spray effect is better.

Further setting: the end part of the diversion column far away from the water distribution pipe is provided with a limiting lug, the end surface of the inner part of the inner cap opposite to the limiting lug is provided with a limiting groove matched with the limiting lug, and the limiting lug is embedded in the limiting groove to limit the diversion column to rotate relative to the inner cap.

Through adopting above-mentioned technical scheme, spacing lug inlays to be located and rotates in order to restrict the relative interior cap of water conservancy diversion post in the spacing recess, has guaranteed that the terminal and interior cap through-hole of runner counterpoint and intercommunication to guaranteed rivers can follow the smooth blowout of shower nozzle.

Further setting: the water delivery pipe is provided with a water pump for supplying water to the water delivery pipe.

By adopting the technical scheme, the pressure of water flow in the water pipe can be adjusted through the water pump, so that the switch of the spray head on the water pipe is controlled.

Further setting: the elastic piece is a pressure spring.

Through adopting above-mentioned technical scheme, the pressure spring is the industry standard part, stable performance and low in production cost, can effectively compress tightly the inner cap on the water distributor.

To sum up, the utility model discloses following beneficial effect has:

1. the automatic water-saving valve has the advantages that the automatic water-saving valve is automatically closed under low water pressure and automatically opened under high water pressure so as to save water;

2. the spray head can be opened only when the water pressure is high, and the inner runner enables the water flow to have high emergent speed, so that the spray head has a better spraying effect;
