Described a plurality of jet aperture 10 diameters are identical, and spacing is identical, and percent opening is slightly less than the cross-sectional area of jet pipe.
Described jet pipe 5 is apart from water surface elevation 0.3～0.5m, and the jet pipe merogenesis is made and installed, and the length of every joint is 1/2 of lock hole width.The jet pipe perforated area is slightly less than its cross-sectional area, needs to guarantee jet orifice after the installation upwards.For having lateral opening sluice, the length of its jet pipe can change according to river water level to be adjusted.
The distance of described jet pipe 5 range gates 4 is greater than 3m.Distance is too near, and then water disturbance is violent before the gate, and gate can accelerate the failure.
Described submersible pump 6 is portable submersible pump, is suspended on the main rope 3.
Described wire rope hoist is a slow-motion hoist, can realize the fine setting of jet pipe underwater penetration.
Described jet pipe is the DN65 coating steel pipe, and steel pipe is a straight tube, and to the jet aperture that bores a row φ 5mm, pitch of holes is 500mm along tube side.Water is injected in the water through the jet aperture, promotes water body and forms spray, stirs water body, suppresses the purpose that water body freezes thereby reach.
Specifically, wire rope hoist 8 is arranged in the sluice left and right banks control building, and the wire rope hoist of selecting for use is a JJMW1 type slow-motion hoist, and its capacity is 10KN, lift 10m, and average rope speed is lower than 4.5m/min.The hoist engine basis is arranged and installed to be needed to cooperate with manufacturer, must make to be built on the rock.
Leading block 2 is arranged in the side at gate pier 1 top, and promptly 100～200mm is pushed up apart from pier in the top side of upstream face.Leading block 2 bases are embedded in the gate pier 1, are processed into the square of 200x200mm with the 5mm steel plate.Leading block 2 pedestals and basis welding, throat depth is not less than 8mm.
Leading block 2 diameter phi 200mm, bearing adopts the self-lubricating composite sliding bearing.During first the installation, require grease up according to bearing producer.After installing, leading block should rotate flexible no jam phenomenon.
Jet pipe 5 is connected with auxilliary wire rope 9 usefulness snap rings, and tightens with nut.It is that 6 * 19-15.5-1400-1-is zinc-plated that auxilliary wire rope adopts model, and its length is determined according to sluice gate pier height and lock hole width.
Jet pipe 5 adopts the DN65 coating steel pipe, and to the jet aperture 10 that bores 1 row φ 5mm, pitch of holes 500mm should guarantee after the installation that the jet aperture upwards along tube side.
Submersible pump 6 adopts the 80QW30-15-3 model, and lift is 15m, and flow is 30m
3/ h, power of motor are 3kW, and water-proof cable length 15m(is not less than the gate pier height).Submersible pump 6 outlets reliably are connected with jet pipe 5 with flexible pipe, guarantee water-tight.Submersible pump 6 is suspended on main rope 3.The submersible pump operating position is placed under water, and can not be placed in the mud, adjust submersible pump placement height according to river channel sedimentation situation and SEA LEVEL VARIATION situation.
The cable of submersible pump and hoist engine inserts in the sluice control system, realizes the automatic control of this device.In the sluice control room, click the mouse slightly and to finish the underwater penetration that jet pipe was opened and adjusted to this device.
Should carry out twice debugging after all devices installation, for the first time before the river course water flowing, mainly check the duty of hoist engine 8 and leading block 2, require hoist engine to operate steadily, jet pipe 5 liftings freely, assembly pulley works well, no jam phenomenon.Check after the river course water flowing for the second time, mainly check the duty of submersible pump and the sealing of jet pipe pipeline, also will regulate the position of jet pipe in water, determine the underwater penetration when spray is maximum.
Below use of the present invention is described:
1, all devices and accessory buying in advance is transported to situ configuration, installation.Carry out field adjustable after the installation, guarantee that all joints of jet pipe and submersible pump must not leak.
2, after anti-freezing device Installation and Debugging are finished, enable when outside temperature is near zero point when winter.Surpass 10 holes as the sluice hole count, two these devices of cover can be set.
3, open hoist engine and regulate the degree of depth of jet pipe in water, note observing near the spray the jet pipe in the river course, select the position of spray maximum, make anti-freeze best results.
4, river water level is lower or deposit when serious, should stop using this device.Otherwise, can cause the submersible pump can't operate as normal, the phenomenon of riverway sludge alluvial jet pipe takes place, thereby can not form spray, the anti-freezing effect of influence.
5, can stop this device after temperature rising and river course freeze thawing.After stopping using, jet pipe and submersible pump are left the water, pull down jet pipe and submersible pump, pipeline and submersible pump are overhauled, safeguard, clean, remove deposit in the jet pipe, jet pipe is kept clear.
6, after cleaning is finished, jet pipe and submersible pump are properly preserved, treated to install and use when arrive winter.
7, before flood season arrival or the sluice gate opening, jet pipe, submersible pump must be left the water, otherwise can influence the sluice water flowing, hinder river course flood.
The present invention is arranged on the sluice in the river course, the river course freezes and opens season in the winter time, before the sluice gate, form non-icing zone together, freeze with water body before the prevention gate, make sluice gate panel exempt from the destruction of ice pressure, reach the prolongation sluice gate purpose in application life, thus the fund of having saved the gate maintenance maintenance.
Above-described embodiment only is used to illustrate technological thought of the present invention and characteristics, its purpose is to make those skilled in the art can understand content of the present invention and implements according to this, can not only limit claim of the present invention with present embodiment, be equal variation or the modification that all disclosed spirit is done, still drop in the claim of the present invention.
