Description
Technical field
The utility model relates to municipal works fields, and in particular to a kind of cut-off equipment and shunting with outer expansion sleeve
Well.
Background technique
At present in shunting well, abandoned stream well and Vatch basin system, system is all by water inlet pipe, outlet pipe and to cut dirty pipe group
At, by drainpipe sanitary sewage or initial rainwater, later period rainwater shunt, wherein sanitary sewage or initial rainwater
Qualified discharge (can also further store initial rainwater after being transported to sewage treatment plant's processing after being trapped to sewage pipe
Or shut off to sewage treatment plant's processing rear discharge up to standard), middle and later periods rainwater is directly discharged in natural water.
The either collecting fitting of the rain pipe of separate system either sewage pipe or combined system in reality, realize shunt or
The device that person is shut off all is the switching for carrying out corresponding outlet pipe using gate or weir gate and cutting dirty pipe, gate valve
Power source is electricity or hydraulic.However there are the following problems for Electronic control in reality: 1, in closed pipeline and Sewage Environment
Inflammable and explosive biogas can be generally generated, it is dangerous therefore electronic in application that the device of general Electronic control class is easy explosion
It can all require the electric control part contacted with biogas that must have explosion prevention function, therefore the valence of automatically controlled class system when controlling the device of class
Lattice are at high cost with regard to more expensive；2, under stormy weather more rugged environment, all can there is a situation where powering off, power-off with
The equipment in shunting well, abandoned stream well or Vatch basin can not work normally afterwards, thus situations such as causing urban waterlogging generation；3, heavy rain
Under weather, there is a situation where waterflooding between a few hours and a couple of days in shunting well, abandoned stream well and Vatch basin, in this way using complete
The suitable electric control gear used under water is excessive with regard to redundancy and cost is excessively high, and the electric control gear waterflooding ability of common IP68 grade
Within a few hours, the case where there is also scarce capacities；4, the device of electric-control system uses non-security voltage, and high-voltage electricity
It is dangerous to be prone to accidents；5, after electrical equipment waterflooding, it is easy electric leakage, there are Danger Electric shock risks；6, control panel (gate,
Weir gate) stroke upward or downward is needed at runtime, expose urban ground, when influencing urban landscape beauty traffic, and constructing
Excavation area is big；7, electric-control system uses the three-phase electricity of 380V, and municipal power grid cannot power, and there are asking for power supply hardly possible
Topic.
Particularly, for requiring the occasion of hidden installation, and for the expense of power supply and the generation of electric-control system not legibility
Certainly.Equally there is also some problems for hydraulic control: hydraulic station uses high-pressure oil pipe, the higher cost of hydraulic station and high-pressure oil pipe；
High-pressure oil pipe rupture oil leak pollutes the environment；After electrical equipment waterflooding, it is easy electric leakage, there are Danger Electric shock risks；Control panel (lock
Door, weir gate) stroke upward or downward is needed at runtime, expose urban ground, influences urban landscape beauty traffic, and construct
When excavation area it is big.
The stroke space of gate or weir gate is larger, and the foundation pit generally dug increases, and the big construction of project amount is inconvenient, and the later period
Repair demolition and installation are more complicated, the severe relatively hazardous unsuitable long-time operation of subsurface environment.
In conclusion being badly in need of a kind of can substituting gate or weir gate, installation, maintenance is convenient, safe and reliable device.
