Abstract
The utility model discloses a piece of underwater detection tool equipment for a high flow-rate environment. The piece of underwater detection tool equipment is composed of opening and closing winching hoisting systems (1) and a permeable detection door (4). The permeable detection door (4) is composed of lifting lugs (5), main beams (6), inclined struts (7), upstream face baffle plates (8), side surface gratings (9) and crawling ladders in channels (10). Rollers (11) are arranged in door grooves at the downstream face of the permeable detection door (4). The piece of underwater detection tool equipment for the high flow-rate environment has following beneficial effects: blocking forces generated when the tool equipment performs up-to-down motion in the door grooves are reduced; security assurance of underwater detection in the state of water flow at the high rate is given to diving personnel for detection; arrangement of above parts ensures smooth release and construction of underwater detection by the tool equipment in the environment of water flow at the high rate; and the piece of underwater detection tool equipment is suitable for popularization and application.
Description
Technical field
The utility model relates to a kind of checkout equipment under water, specifically, relates to a kind of high flow rate environment undersea detection tooling device.
Background technology
During the construction of hydropower stations, smooth construction in order to ensure water conservancy project structure such as dam, power plant buildings, general all in the mode of construction diversion, solve construction section and cross water problems, dam builds up to be possessed after water storage condition, must carry out lower lock shutoff to Diversion Tunnel, but due to Diversion Tunnel rolling erosive wear through long-term high flow rate current or silt, falling rocks during Dam Construction, gate slot and Di Kan position be regular there will be destroy or gate slot in have grit stone jam, affect the whereabouts of Diversion Tunnel gate.In order to guarantee the normal descend of gate, before lower lock, must understand the damaged condition of gate slot and end bank, prevent from occurring jam in the halfway of lower lock, delay the normal retaining in power station.Generally, the flow velocity during Diversion Tunnel overcurrent is all greater than the allowed band that diver enters safely water, and great majority are all over 5m/s, and in the case, diver cannot dive, and safety cannot be guaranteed.Prior art also cannot solve an above-mentioned difficult problem.
Utility model content
In order to overcome the defect existing in prior art; the utility model provides a kind of high flow rate environment undersea detection tooling device; this equipment is to adopt steel work to be processed into the protection gallery of limited current obstruction area; utilize the own wt of steel work and the roller that back side arranges; drag in the time of can reducing tooling device and move up and down in gate slot, guarantees that tooling device can transfer smoothly under high-velocity flow environment.Its technical scheme is as follows:
A high flow rate environment undersea detection tooling device, forms by opening and closing elevator tackling system and dankness type detection door:
Described dankness type detection door consists of cat ladder in main hoisting ear, girder, diagonal brace, upstream face dividing plate, side grid, passage;
The back side gate slot place of described dankness type detection door is provided with roller.
Further preferably, also comprise upstream face watertight shutter and grid.
Further preferably, also comprise horizontal grate.
Further preferably, described dankness type detection door is provided with end bank inspection gallery and the vertical passage that checks.
The beneficial effects of the utility model:
The utility model adopts steel work to be processed into the gallery protective device of limited current obstruction area; utilize the own wt of steel work and the roller that back side arranges; drag in the time of can reducing tooling device and move up and down in gate slot, guarantees that tooling device can transfer smoothly and promote under high-velocity flow environment.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model high flow rate environment undersea detection tooling device;
Fig. 2 is the longitudinal sectional drawing of the utility model high flow rate environment undersea detection tooling device.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in more detail.
See figures.1.and.2, a high flow rate environment undersea detection tooling device, forms by opening and closing elevator tackling system 1 and dankness type detection door 4: described dankness type detection door 4 consists of cat ladder 10 in hanger 5, girder 6, diagonal brace 7, upstream face dividing plate 8, side grid 9, passage; The back side gate slot place of described dankness type detection door 4 is provided with roller 11 and eliminates the resistance of operation up and down, prevents that detection door is difficult to fall by the crowded gate slot downstream face that is attached to of hydraulic pressure.The scope detecting in order to expand base plate, the utility model also comprises upstream face watertight shutter 12 and grid 13, shoots with video-corder probe and can stretch out and carry out the detection of base plate expanded scope from grid.Upstream face watertight shutter 12 is movable device, and while opening and closing detection door, open upstream face watertight shutter 12 or close in the above space of the water surface, gate slot tunnel before utilizing water or after water outlet.For the ease of the detection of bank at the bottom of gate slot, bottom gallery is all laid horizontal grate 14, and back side is all vertical grid, to guarantee the safety between diver's operational period.Described dankness type detection door 4 is provided with end bank inspection gallery and the vertical passage that checks.The utility model can be for the detection of gate slot vertical section, end bank and base plate face, and diver can carry out work by the dive of vertical inspection passage in base plate inspection gallery.
The above; it is only the preferably specific embodiment of the utility model; protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses, the simple change of the technical scheme that can obtain apparently or equivalence are replaced and are all fallen in protection domain of the present utility model.
Claims (4)
1. a high flow rate environment undersea detection tooling device, is characterized in that, by opening and closing elevator tackling system (1) and dankness type detection door (4), is connected in sequence:
Described dankness type detection door (4) is connected in sequence by cat ladder (10) in hanger (5), girder (6), diagonal brace (7), upstream face dividing plate (8), side grid (9), passage;
