Background technique

In order to keep the road clean and a good air environment, urban streets use sprinklers to sprinkle water every day. In order to be as clean as possible and sprinkle water evenly, the speed of sprinklers is often very slow, which will affect traffic operations to a certain extent. In order to prevent As a result of traffic congestion, the working hours of sprinklers often choose to run in the early morning when there are fewer vehicles, so the working hours of the staff are relatively tight.

At present, there is another way to solve the above problems, which is to use the space of roadside guardrails or road slippery belts to lay pipes, and spray water through the pipes to clean and purify the road surface. However, in order to ensure water pressure, the number of nozzles installed on the pipes Limited, and the nozzles are set at intervals, which will cause uneven sprinkling.

1. In this technical solution, the pipe wall of the main pipe is evenly provided with a through hole sealed by a tapered plug in the length direction. When the sliding sealing block passes through the hole, the lever in the water collection groove passes through the tapered plug. When the taper plug is pressed down, the through hole is connected, and the water in the main pipe enters the water collection groove, then gathers into the conduit, sprays out from the jet nozzle, and sprinkles on the road surface. The beneficial effect produced in this way is that the movement of the sliding sealing block is continuous, the water spraying process is continuous without gaps, the water collecting groove spans a plurality of through holes, and the conduction number of the through holes is stable, so the jet rate of the water flow is stable. The sliding sealing block travels along the main pipeline through the power device, and sprays water outward through only one conduit, reducing pipeline branches and ensuring water pressure. More importantly: the main pipe serves as both a water supply pipe and a guide rail. The spray device does not need additional water supply pipes to track its movement. This greatly simplifies the pipes, improves durability and facilitates maintenance.

This technical solution can be connected with a spray head through a three-position three-way reversing valve, and the spray head can spray water mist, remove dust and haze, and increase humidity, and control the three-position three-way reversing valve through the control circuit, which can be realized The function conversion of sprinkling and spraying greatly simplifies the division of labor in road administration and the labor intensity of staff, which is conducive to smooth traffic.

A water pressure sensor is installed in the main pipeline, and the water pressure sensor can measure whether the water pressure in the main pipeline is stable, so as to indirectly judge whether there is leakage on the side wall or whether the three-position three-way reversing valve is working normally.

Before water spraying or spraying, the control circuit can start the speaker and warning lights to remind passing vehicles and pedestrians. The wireless communication module can promote the unified remote management of road administration, and make comprehensive watering or spraying commands according to the conditions of each road section. The solar photovoltaic module can supply power to the storage battery in the power supply circuit, so that the control circuit can run independently from the grid, which is beneficial to reduce wiring and save electric energy.
