Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy engineering, in particular to a Buddha's hand type sprinkler head protective cover. Background Art

[0002] Gates are control facilities used to close and open water discharge channels. They are an important part of hydraulic structures and can be used to intercept water flow, control water levels, regulate flow, discharge sediment and floating objects, etc. Gates include revolving gates and vertical gates. In reality, nozzles are installed on gates to beautify the gate locations, thus forming landscape fountains to beautify the city. However, installing nozzles on the upper end of the gates will cause accumulation of impurities, especially cloth bags and branches. Long-term accumulation will cause the upper end of the gate to be clogged with garbage, seriously affecting the opening and closing of the gates and the water spraying action of the nozzles.

[0003] Based on this, a Buddha's hand type nozzle protection cover is now provided to eliminate the disadvantages of the existing device. Utility Model Content

[0021] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides a Buddha's hand type nozzle protection cover, including a plurality of shielding units 300 arranged at the upper end of the gate dam body 200, the position of each shielding unit 300 corresponds to the position of the nozzle 100, the lower end of the nozzle 100 is connected to the water supply pipeline inside the gate dam body 200, the shielding unit 300 includes a first shielding body 301 and a second shielding body 302, the first shielding body 301 and the second shielding body 302 are hemispherical structures or rectangular structures, and the outer side of the lower end of the nozzle 100 is provided with a shielding unit 300. The bottom of the second shielding body 302 and the lower end of the first shielding body 301 are rotatably connected to the outer side of the blocking chassis 308 through a transmission shaft 309. The first shielding body 301 and the second shielding body 302 are connected to a driving unit for driving the opening and closing of the first shielding body 301 and the second shielding body 302. The first shielding body 301 and the second shielding body 302 are driven by the driving unit to rotate to both sides. At this time, the nozzle 100 will be exposed, and the water spraying operation can be performed. When not in use, the first shielding body 301 and the second shielding body 302 are closed to protect the nozzle 100;

[0022] A sealing ring is provided at the closed contact position of the second shielding body 302 and the first shielding body 301, and a sealing ring matching the first shielding body 301 and the second shielding body 302 is provided on the outside of the blocking chassis 308, so that after the first shielding body 301 and the second shielding body 302 are closed, the nozzle 100 can be better protected;

[0023] The first shielding body 301 and the second shielding body 302 are made of stainless steel or transparent plastic. The transparent plastic material can be used to better observe the state of the internal nozzle 100, and a lighting lamp can be set at the position of the blocking chassis 308 to improve the landscape effect.

[0024] The driving unit includes a second opening and closing gear 311 and a first opening and closing gear 307 arranged on two transmission shafts 309, the second opening and closing gear 311 is arranged on the outside of the second shielding body 302, the second opening and closing gear 311 is arranged on the outside of the first shielding body 301, the second opening and closing gear 311 is meshed with the first opening and closing gear 307, the first opening and closing gear 307 or the second opening and closing gear 311 is connected to a driving member for driving the rotation thereof, the driving member drives the transmission gear 306 to rotate, the transmission gear 306 and the second opening and closing gear 311 cooperate with each other, so that the first shielding body 301 and the second shielding body 302 rotate synchronously;

[0025] The driving member includes a transmission slide bar 303 slidably arranged on the upper end of the gate dam body 200, and the transmission slide bar 303 is slidably arranged with a guide sleeve 304 on the upper end of the gate dam body 200.

The upper end of the transmission slide bar 303 is provided with a plurality of transmission racks 305 matching with the transmission gear 306. Under the push of the pusher 310, the transmission slide bar 303 drives the plurality of transmission racks 305 to move horizontally. When the transmission racks 305 move, they match with the transmission gear 306, thereby providing power for the rotation of the first opening and closing gear 307, thereby driving the plurality of shielding units 300 to open and close synchronously:

[0026] The pusher 310 is a hydraulic push rod, a pneumatic push rod or a linear motor, as long as it can provide power for the transmission slide rod 303 to slide;

[0027] Working principle: In actual use, the driving member 310 drives the transmission slide rod 303 to slide along the guide sleeve 304, and the multiple transmission racks 305 on the transmission slide rod 303 will also move, and the transmission rack 305 matches the transmission gear 306, thereby driving the first opening and closing gear 307 to rotate, and the first opening and closing gear 307 matches the second opening and closing gear 311, thereby driving the multiple first shielding bodies 301 and the second shielding bodies 302 to open and close. When the nozzle 100 is working, the first shielding body 301 and the second shielding body 302 are opened, and when the nozzle 100 is not working, the first shielding body 301 and the second shielding body 302 are closed, thereby protecting the nozzle 100. In this way, when the gate dam body 200 rotates underwater, the nozzle 100 will also be protected to avoid the problem of impurities accumulating on the upper end of the gate dam body 200.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
