Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail:
As Fig. 1, shown in 2, anti-freezing device for water gate of the present invention, anti-freezing device is arranged in before gate 4, anti-freezing device comprises submersible pump 6, jet pipe 5, multiple leading block 2 and wire rope hoist 8, the top side of each gate pier 1 upstream face is provided with a leading block 2, submersible pump 6 and the traverse jet pipe 5 before gate is positioned in the water before gate 4, wire rope hoist 8 is arranged in the control building on bank, wire rope hoist 8 is connected with multiple leading block 2 by main rope 3, jet pipe 5 is connected with main rope 3 respectively by leading block 2 by multiple auxiliary wire rope 9, wire rope hoist 8 is opened and drives main rope 3 to regulate jet pipe 5 and the degree of depth of submersible pump 6 in water, jet pipe 5 is straight tube, pipe is drilled with multiple jet aperture 10 aiming at top, submersible pump 6 communicates with jet pipe 5.
Described multiple jet aperture 10 diameter is 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 jet pipe merogenesis makes and installs, and the length often saved is 1/2 of lock hole width.Jet pipe perforated area is slightly less than its cross-sectional area, needs to ensure jet orifice upwards after installation.For having lateral opening sluice, the length of its jet pipe can adjust according to river water level change.
The distance of described jet pipe 5 range gate 4 is greater than 3m.Distance is too near, then before gate, water disturbance is violent, and gate can accelerate the failure.
Described submersible pump 6 is movable submersible pump, is suspended on main rope 3.
Described wire rope hoist is slow-motion hoist, can realize the fine setting of jet pipe underwater penetration.
Described jet pipe is DN65 coating steel pipe, and steel pipe is straight tube, and bore the jet aperture of a row φ 5mm along pipe direction, pitch of holes is 500mm.Water is injected in water through jet aperture, promotes water body and forms spray, stir water body, thus reach the object suppressing water body to freeze.
Specifically, wire rope hoist 8 is arranged in sluice left and right banks and controls in building, and the wire rope hoist selected is JJMW1 type slow-motion hoist, and its capacity is 10KN, lift 10m, and average rope speed is lower than 4.5m/min.Hoist engine basis is arranged and is installed and need coordinate with manufacturer, must make to be built on the rock.
Leading block 2 is arranged in the side at gate pier 1 top, i.e. the top side of upstream face, distance pier top 100 ~ 200mm.Leading block 2 basis is embedded in gate pier 1, is processed into the square of 200x200mm with 5mm steel plate.Leading block 2 pedestal and base solder, throat depth is not less than 8mm.
Leading block 2 diameter phi 200mm, bearing adopts self-lubricating composite sliding bearing.During first installation, require grease up according to bearing producer.After installing, leading block should rotate flexibly without jam phenomenon.
Jet pipe 5 is connected with snap ring with auxiliary wire rope 9, and clamps with nut.Auxiliary wire rope adopts model to be that 6 × 19-15.5-1400-1-is zinc-plated, and its length is determined according to Sluice Pier height and lock hole width.
Jet pipe 5 adopts DN65 coating steel pipe, bores the jet aperture 10, pitch of holes 500mm of 1 row φ 5mm, should ensure jet aperture upwards after installation along pipe direction.
Submersible pump 6 adopts 80QW30-15-3 model, and lift is 15m, and flow is 30m
3/ h, power of motor is 3kW, and water-proof cable length 15m(is not less than gate pier height).Submersible pump 6 outlet flexible pipe is reliably connected with jet pipe 5, ensures water-tight.Submersible pump 6 is suspended on main rope 3.Submersible pump operating position is placed under water, and can not be placed in mud, according to river channel sedimentation situation and SEA LEVEL VARIATION situation adjustment submersible pump placing height.
Wire rope hoist 8 arranges high-low limit protection and overload protection device.Initial stage, when installing, be placed on by jet pipe 5 on gate floor 7 and carry out, this position was the lower limit position of wire rope hoist 8.Upper extreme position is that jet pipe 5 is left the water to gate pier top, and after arriving this position, hoist engine should quit work.
In the cable access Sluice Control System of submersible pump and hoist engine, realize the automatic control of this device.Indoor at water gate control, click the mouse slightly and can complete the underwater penetration of the unlatching of this device and adjustment jet pipe.
Should carry out twice debugging after all devices installation, first time, the main duty checking hoist engine 8 and leading block 2, require that hoist engine operates steadily, jet pipe 5 was elevated freely, and assembly pulley works well, without jam phenomenon before river course water flowing.Second time checks after river course water flowing, and the main inspection duty of submersible pump and the sealing of jet pipe pipeline, also will regulate the position of jet pipe in water, determine underwater penetration when spray is maximum.
Below use procedure of the present invention is described:
1, all devices and accessory are purchased in advance, are transported to situ configuration, installation.Carry out field adjustable after installation, ensure that all joints of jet pipe and submersible pump must not leak.
2, after anti-freezing device Installation and Debugging complete, when winter outside temperature enable close to during zero point.If sluice hole count is more than 10 holes, this device of two covers can be set.
3, open hoist engine and regulate the degree of depth of jet pipe in water, note observing the spray in river course near jet pipe, select the position that spray is maximum, make anti-freeze best results.
4, river water level is lower or when depositing serious, should stop using this device.Otherwise submersible pump can be caused normally to work, and the phenomenon of riverway sludge alluvial jet pipe occurs, thus can not form spray, affects Anti-freezing effect.
5, this device can be stopped after temperature rising and river course freeze thawing.After stopping using, jet pipe and submersible pump are left the water, pulls down jet pipe and submersible pump, pipeline and submersible pump are overhauled, safeguard, cleaned, remove deposit in jet pipe, jet pipe must be made to keep clear.
6, after having cleared up, jet pipe and submersible pump are properly preserved, installs and uses when winter arrives.
7, arrive flood season or before water gate unlatching, jet pipe, submersible pump must be left the water, otherwise sluice water flowing can be affected, hindering river course flood.
The present invention is arranged on the sluice in river course, river course freezes and opens season in the winter time, non-icing region is together formed before water gate, freeze to prevent water body before gate, water gate panel is made to exempt from the destruction of ice pressure, reach the object extending water gate application life, thus save the fund of gate maintenance maintenance.
Above-described embodiment is only for illustration of technological thought of the present invention and feature, its object is to enable those skilled in the art understand content of the present invention and implement according to this, only can not limit the scope of the claims of the present invention with the present embodiment, namely the equal change done of all disclosed spirit or modification, still drop in the scope of the claims of the present invention.
