The steam generator pipe plate sludge flushing spray head comprises a front spray nozzle block and a back spray nozzle block, wherein spray cavities are respectively arranged inside the front spray nozzle block and the back spray nozzle block, in addition, spray nozzles communicated with the spray cavities are adopted, the steam generator pipe plate sludge flushing spray head also comprises a plurality of engaged gears driven by a motor, the two spray nozzle blocks are respectively connected with corresponding gears, and the spray nozzle blocks are driven to rotate through the gears. In the work process, the two groups of spray nozzle blocks rotate in the opposite direction around the axial line, so the two groups of spray nozzle blocks can be used for simultaneously and effectively flushing pipe plates arranged at the two sides of a central pipe gallery, only the spray nozzles at one side can realize the effective flushing on the pipe plates in the work process in the ordinary parallel spray nozzle arrangement mode, the spray nozzles at the other side have the main effect of balancing the counter-acting force of high-pressure water, and the flushing efficiency is effectively improved.
Description
Technical field
The utility model belongs to nuclear power station steam generator maintenance maintenance technology, is specifically related to the hydro-peening structure in a kind of steam generator tube sheet body refuse flusher.
Background technology
Each nuclear power country of the world all attaches great importance to the body refuse of steam generator (hereinafter referred SG) problem of cleaning, and has also therefore developed the cleaning method of variety of way.Comparatively speaking, it is low, simple that mechanical cleaning (S/L)---method that mud gun cleans has cost, the advantage that washing time is short, and desludging efficiency is higher.So nuclear power station, all using mechanical cleaning as routine means, cleans evaporimeter during each refueling outage both at home and abroad at present.
The nozzle arrangements that more existing representational SG tube sheet body refuses rinse both at home and abroad: 360 ° of full rotation parallel nozzles that cantilever rifle is supporting, Control Nozzle forward/reversion realizes the flushing of both sides tube sheet (directly to 30 ° of the rotation deflections of rifle head and oblique rifle head), this structure can effectively be eliminated High-Pressure Water range and the reaction force that brings, but this structure in use flush efficiency is low, do not make full use of the ability of high-pressure washing system.
And for angle between the SG(pipe of heat-transfer pipe rounded projections arranged, be 30 °, 90 ° and 150 °), also do not have a kind of can follow tube sheet crawl device tube sheet center piping lane motion, clean nozzle structure efficiently.
Summary of the invention
The purpose of this utility model is to provide a kind of steam generator tube sheet body refuse Flushing nozzle for heat-transfer pipe rounded projections arranged.
The technical solution of the utility model is as follows:
A steam generator tube sheet body refuse Flushing nozzle for heat-transfer pipe rounded projections arranged, it comprises front nozzle piece and rear nozzle piece, both are equipped with spray chamber in inside, and are provided with the nozzle communicating with spray chamber; Also include several meshed gears of driven by motor, two nozzle block connect with corresponding gear respectively, by gear driven nozzle block, rotate.
In the steam generator tube sheet body refuse Flushing nozzle of above-mentioned heat-transfer pipe rounded projections arranged: described gear has 6, vertical direction is 3, horizontal direction is 4, the gear joining overlaps, one of vertical direction the top is gear A, be followed successively by gear B, gear C downwards, in horizontal direction with gear C engagement be gear D, be outwards followed successively by gear E, gear F; The output shaft of motor is connected with the gear shaft of the gear A of the top in vertical direction; The gear shaft of front nozzle piece and gear C is fixed, and the gear shaft of rear nozzle piece and gear F is fixed.
In the steam generator tube sheet body refuse Flushing nozzle of above-mentioned heat-transfer pipe rounded projections arranged: one end of front nozzle piece and rear nozzle piece is all processed with outstanding joint, by joint, nozzle block is fixedly connected with corresponding gear.
Remarkable result of the present utility model is: during due to two groups of nozzle block work, be to rotate backward around axis, so two groups of nozzle block can effectively be rinsed the tube sheet of piping lane both sides, center simultaneously, and common parallel nozzle arrangement when work can only a side nozzle effectively rinse tube sheet, the Main Function of the nozzle of an other side has been the reaction force of balance water under high pressure, effectively improves flush efficiency.

The specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As shown in Figure 1, Figure 2 and Figure 3, nozzle block 1 is placed before and after having two, and its inside is processed with spray chamber, in each nozzle block 1, nozzle 2 is installed, and number can arrange 4 or more for each nozzle block 1.Each nozzle communicates with the spray chamber of the nozzle block 1 at place.
Above nozzle block 1, be motor 9, a side mounting teeth roller box 3 of motor 9, gear-box 3 inside are provided with some gears 6 by bearing 5, and bearing 5 is enclosed within outside the gear shaft of gear 6, then by end cap 4, gear is located.In the present embodiment, gear 6 is provided with 6 altogether, and vertical direction is 3, and horizontal direction is 4, and the gear joining overlaps, can be for horizontal direction, also can be regarded as vertical direction and adjacent gear 6 engagements.One of vertical direction the top is gear A 6.1, is followed successively by gear B 6.2, gear C 6.3 downwards, in horizontal direction with gear C 6.3 engagement be gear D 6.4, be outwards followed successively by gear E6.5, gear F6.6.
The output shaft of above-mentioned motor 9 is connected with the gear shaft of the gear A 6.1 of the top in vertical direction.
As shown in Figure 1, one end of nozzle block 1 is processed with outstanding joint, and this joint stretches in the gear installing hole of gear-box 3, and is fixedly set in outside corresponding gear shaft, by O RunddichtringO 8, guarantees the sealing connecting.The gear shaft of the joint of front nozzle piece 1.1 and gear C 6.3 is fixed, and the gear shaft of the joint of rear nozzle piece 1.2 and gear F6.6 is fixed.
The other end of nozzle block 1 passes through to connect water supply system 11 by routine techniques.
During work, motor 9 starts, and drives gear A 6.1 motions that are attached thereto, due to each adjacent gear engagement, so gear C 6.3 and also rotation thereupon of gear F6.6, the front nozzle piece 1.1 and the rear nozzle piece 1.2 that are therefore connected with above-mentioned two gears also rotate.Due to adjacent gear engagement, so gear C 6.3 is also contrary with gear F6.6 rotation direction.
In the present embodiment, gear A 6.1 and gear B 6.2 engagements, gearratio is 1:1.Gear B 6.2 and gear C 6.3 engagements, gearratio is 9:10.Gear C 6.3 and gear D 6.4 engagements, gearratio is 10:11.Gear D 6.4 and gear E6.5 engagement, gearratio is 1:1.Gear E6.5 and gear F6.6 engagement, gearratio is 11:10.Therefore, the gear C 6.3 of now selecting is identical with gear F6.6 rotating speed, and direction of rotation.Therefore can realize two row's nozzles whiles, synchronized, rotating in same direction.
Meanwhile, water supply system 11 storage high pressure water are also evenly distributed in nozzle block 1, by nozzle 10, evenly spray.
Also can slide block or like be installed on the lower surface of water supply system 11, while guaranteeing that whole device contacts with inner-walls of duct, frictional force reduces, and makes to walk smooth and easy.
