Description
Technical field
The present invention relates to a kind of overhead road of city bridge protective railings nozzles.
Background technique
China's water resources shortage, so more and more cities are carrying out sponge urban construction, that is, it can be just when raining
Water suction, water storage, infiltration, water purification are realized in ground, by the water stored " release " and are used when needing.Current rainwater storage technology
It is very perfect, but how the rainwater of storage effectively to be recycled into this problem there are no many solutions.Especially
China city proper overpass is numerous, and a large amount of rainwater can be collected when rainy, and conventional means are to be used to pour by this part rainwater
Vegetation below overpass, but this method is lower to the utilization rate of rainwater.However, overpass road surface is past when summer high-temperature
Contact needs artificial watering to cool down, so if can will from overhead bridge floor collected rainwater be sprayed onto as needed it is overhead
On bridge, it will greatly improve the utilization rate of rainwater.But traditional duck-beak type or rotating nozzle is unable to reach preferable spray
Effect, and overhead bridge floor lime, the grains of sand are more, plug nozzle are easy, so designing a kind of overhead road of city bridge protective railings nozzle
With regard to extremely urgent.
Summary of the invention
The technical problem to be solved by the present invention is provide it is a kind of convenient for the overhead road of city bridge protective railings of piping connection spray
Mouth.

Spray orifice is provided on half side tube-wall of nozzle body, the internal diameter of spray orifice is gradually increased from inner end to outer end, the top bus of spray orifice
In the horizontal direction, the line at the center at the center and collar extension of spray orifice internal orifice and the angle of the top bus are 10 ° -20 °, spray orifice
The center of collar extension is lower than the center of spray orifice internal orifice, and spray orifice protective device includes protective cover, connecting shaft, gear, rack gear, piston and bullet
Spring, protective cover are half cylinder, and the top edge of half cylinder is provided with groove, and connecting shaft rotation is plugged on the barrel of nozzle body, connects
Axis one end is fixedly connected with the intracorporal gear of nozzle is located at, and the other end of connecting shaft is fixedly connected with the top of protective cover, piston
It is slidably arranged in nozzle body, spring one end is fixedly connected with the bottom of nozzle body, and the other end of spring is fixedly connected on piston
Downside on, one end of rack gear is fixed on the upper side of piston, rack and pinion engagement, when spring in the raw
When, piston is located at the upper end of spray orifice, and protective cover is tightly attached on the outer tube wall of nozzle body and is covered on the spray orifice of nozzle body barrel,
When spring is compressed to a certain degree, piston is located at the lower section of spray orifice, and the axis of protective cover and the axis angle of nozzle body are
90 °, the edge of the groove is attached on the barrel of nozzle body.For the ease of with piping connection, connector of the present invention
Outer wall is provided with the screw thread for connecting line.
In order to expand spray area, spray orifice of the present invention is provided with three rows, and every row has 6 spray orifices, the phase of every row
The angle of adjacent spray orifice is 30 °.
The beneficial effects of the present invention are: spray orifice protective cover is arranged on the surface of nozzle body in the present invention, it can be to avoid overpass
On the obstruction spray orifice such as lime, sand grains, when nozzle when in use, water flow pressure acts on piston, allows piston moves downward, will lead to
Rack and pinion engagement is crossed, by the transform linear motion of piston at the rotation of gear, gear drives protective cover to be rotated up exposing spray
Mouth, the excessively high droplet that protective cover can also stop spray orifice to spray, avoids for water being sprayed on the vehicle of traveling, when piston does not make
Used time, spring are stretched by elastic force, and protective cover covers spray orifice again.The present invention is suitable for installing and using on overpass, both protects
The obstruction spray orifice such as road surface spraying effect is demonstrate,proved, and has been avoided that lime sand grains.

Specific embodiment
Overhead road of city bridge protective railings nozzle as depicted in figs. 1 and 2, including connector 1, nozzle body 4 and spray orifice protection dress
It sets, connector 1 and nozzle body 4 are cylinder, and cylinder is vertically arranged, and the outer wall of connector 1 is provided with the spiral shell for connecting line
Line, connector 1 are fixedly connected with the upper end of nozzle body 4, are connected to inside connector 1 and nozzle body 4, half side tube-wall of nozzle body 4
On be provided with spray orifice 5, spray orifice 5 is provided with three rows, and every row has 6 spray orifices 5, and the angle of the adjacent orifices 5 of every row is 30 °, spray
The internal diameter in hole 5 is gradually increased from inner end to outer end, the top bus of spray orifice 5 in the horizontal direction, the center of 5 internal orifice of spray orifice and
The line at the center of collar extension and the angle of the top bus are 10 ° -20 °, and preferably 15 °, the center of 5 collar extension of spray orifice is lower than spray orifice
The center of 5 internal orifices, as shown in Figure 3 and Figure 4, spray orifice protective device include the gear 10, two of connecting shaft 2, two of protective cover 3, two
A rack gear 9, piston 7 and spring 6, protective cover 3 are half cylinder being divided into two passed through from body centre, the top edge of half cylinder
Be provided with groove, two connecting shafts 2 are fixedly connected with the two sides of the groove of half cylinder respectively, 2 one end of connecting shaft be located at nozzle body 4
Interior gear 10 is fixedly connected, and the other end of connecting shaft 2 is fixedly connected with the top of protective cover 3, and piston 7 is sliding by piston ring 8
The dynamic inner cavity that nozzle body 4 is arranged in, piston ring 8 are fixed on piston 7, are mainly used for the sealing of piston 7 and are prevented piston 7 excessive
Abrasion, 6 one end of spring are fixedly connected with the bottom of nozzle body 4, and the other end of spring 6 is fixedly connected on the downside of piston 7,
One end of rack gear 9 is fixed on the upper side of piston 7, and the upper end of rack gear 9 is made into coniform, rack gear 9 to reduce hydraulic pressure impact
Engaged with gear 10, two gears 10 and rack gear 9 are symmetrical about the central axis of nozzle body 4, when spring 6 in the raw
When, piston 7 is located at the upper end of spray orifice 5, and protective cover 3 is tightly attached on the outer tube wall of nozzle body 4 and is covered on the barrel of nozzle body 4
On spray orifice 5, when spring 6 is compressed to a certain degree, piston 7 is located at the lower section of spray orifice 5, the axis and nozzle body 4 of protective cover 3
Axis angle be 90 °, the edge of 3 groove of protective cover is attached on the barrel of nozzle body 4.
Working principle: when summer bridge deck temperature is higher, when needing spray cooling, water pump can be by collected rainwater
Be pumped into cellular nozzle body 4, hydraulic pressure P starts to act on the top of piston 6, according to formula can calculate piston 7 by
Water pressure be F=1/4P* π d2, wherein d is piston diameter.And according to camber of spring formula F=k*x, k is spring system
Number, x is spring deflection.Usual overpass spray system need to meet hydraulic pressure when being 0.5Mpa, and water spray distance can cover two
Lane, width can reach 6m.So above-mentioned two equation may be used to determine the type selecting and installation site of spring 6 and piston 7, guarantee
Hydraulic pressure is that 0.5Mpa is the position that piston 7 can move down into that all spray orifices 5 are opened.When nozzle when in use, piston 7 is in water flow
Start to move down under effect, piston 7 moves down moving down with carry-over bar 9, and gear 10 is engaged with rack gear 9, and rack gear 9 is with 10 turns of moving gear
Dynamic, gear 10 drives protective cover 3 to be rotated up by connecting shaft 2, and when hydraulic pressure is 0.5MPa, protective cover 3 is just rotated up
