Abstract
The utility model relates to a sensing type self-energy-dissipating pressureless water drainage system for earth-rockfill dams, which mainly solves the problem that the ordinary drainage system for medium and small reservoirs has high cost and needs to be attended by specially assigned staff. The water drainage system comprises a service gate, a bulkhead gate and a drainage culvert, the service gate is arranged on the top of a semi-spherical shell, the semi-spherical shell is arranged on the top of a cylinder, one side of the cylinder is connected with the drainage culvert, the bulkhead gate is arranged at the joint between the cylinder and the drainage culvert, and the opening and closing of the service gate are controlled by a main control system, which is provided with a level sensing device. The cost of the automatic pressureless water drainage system is low, construction is convenient, reservoirs can be automatically managed and controlled, water can smoothly flow into the drainage culvert after the energy of water is dissipated by the water drainage system, so that the culvert and the downstream riverway cannot be severely washed, the structure is simple, and the water drainage system is suitable for use on medium and small reservoirs.
Description
Technical field
The utility model relates to a kind of water discharge implement for reservoir, specifically the device that can discharge water automatically on earth dam or earth and rockfill dam.
Background technology
The culvert that discharges water of reservoir is one of building important in the reservoir hinge, and it can be used for irrigation, diversion and power, water conservancy diversion, emptying reservoir, but the also double as flood discharge that has, row are husky.In middle-size and small-size reservoir engineering, the culvert of burying underground under small reservoir dam or the Earth and Rockfill Dam that discharges water particularly then mostly is used for irrigating.According to the flow-shape in the culvert, culvert generally is divided into three kinds of pressure flow, pressure free current and half pressure flows, according to the traffic control of engineering and the situation of actual engineering, great majority adopt not have and press the water device in middle-size and small-size reservoir, service bridge and service depot need be set, this structure needs a large amount of construction investments, structure and construction are all complicated, also need to want the professional to keep an eye on, water level discharges water when too high and can make current too urgent, the culvert that discharges water is caused very big washing away, reduce the application life of culvert, dam body is also had damage.
Summary of the invention
Many weak points at existing water discharge implement for reservoir, the utility model provides a kind of economical superior, jettison gear of saving construction investment, this device can be controlled Service gate automatically by induction installation is set, energy dissipator can make current smooth-going, reduce current to the washing away of culvert and downstream river course, thereby realize that automatic energy dissipating do not have the water of pressing.
The concrete technical scheme that the utility model adopts is: a kind of induction type does not have the water of pressing device from the energy dissipating earth and rockfill dam, comprise Service gate, Emergency Gate and water outlet culvert, it is characterized in that: described Service gate is located at a hemispherical shell top, hemispherical shell is located at a cylindrical tube top, cylindrical tube one side connects the water outlet culvert, cylindrical tube and water outlet culvert junction are provided with Emergency Gate, the switch of described Service gate is controlled by master control system, and master control system is provided with a water level inductor.
Automatically control opening and closing of Service gate by water level inductor and master control system, master control system can use 555 timers to accept the signal of water level inductor, the switch of control Service gate motor, also can use the reception of other signal induction devices realizations, reach automatic control Service gate switching purposes water level signal; The hemispherical shell top is provided with Service gate, and current can enter in the cylindrical tube by Service gate, is rotated in cylindrical tube, shears, and to reach the purpose to the water energy dissipating, current can be flowed out more reposefully from the water outlet culvert; Emergency Gate is open mode at ordinary times, because its use is fewer, switch is located on the dam body.
The switch of described Service gate is located at hemispherical shell inside, drive by submersible machine, also can pass through other closures of drive unit driving switch under water, described water level inductor is hydraulic gage or float, hydraulic gage is suitable for bigger reservoir to be used, and float can use on small reservoir.
Described hemispherical shell is provided with into people's gate and extract duct, advances people's gate and makes things convenient for the maintainer to enter the inner place under repair of this jettison gear, because its use is less, for reducing the cost of this device, so be located at hemispherical shell one side.
The beneficial effects of the utility model are: it is low that this automation does not have the water of pressing installation cost, and easy construction is convenient to realize the target of automatic management of reservoir unmanned and control.Construction investment is the 10%-25% of tower structure, and current flow into the culvert that discharges water through after this jettison gear energy dissipating smooth-goingly, and minimizing is washed away culvert and downstream river course, increases the application life of culvert, and is simple in structure, is suitable for using on middle-size and small-size reservoir.
Description of drawings
Main pseudosection when accompanying drawing 1 uses for the utility model
Accompanying drawing 2 is the view of A-A among Fig. 1
Among the figure: 1 dam body, 2 hemispherical shells, 21 extract ducts, 3 Emergency Gates, 31 inspection switch, 4 Service gates, 41 submersible machines, 42 cylindrical tubes, 5 water outlet culverts, 6 brace tables, 7 advance people's gate, 8 hydraulic gages.
The specific embodiment
As shown in Figure 1, this induction type does not have the water of pressing device from the energy dissipating earth and rockfill dam, Service gate 4 is located at a hemispherical shell 2 tops, hemispherical shell 2 is located at a cylindrical tube 42 tops, cylindrical tube 42 1 sides connect the water outlet culvert, water outlet culvert 5 is located at below the dam body 1, cylindrical tube 42 and water outlet culvert 5 junctions are provided with Emergency Gate 3, the switch of Service gate 4 is located at hemispherical shell 2 inside, drives by submersible machine 41, and submersible machine 41 is located on the brace table 6, cylindrical tube 42 structures can adopt concrete structure, also can adopt the structure of other materials, hemispherical shell 2 can adopt concrete structure, also can adopt the cast iron structure.
By hydraulic gage 8 hydraulic signal is issued master control system, realize opening of control Service gate automatically with closed, master control system uses 555 timers to accept the signal that hydraulic gage 8 sends, the switch of control Service gate 4 motor, current can enter in the cylindrical tube by Service gate, in cylindrical tube, be rotated, shear,, current can be flowed out more reposefully from water outlet culvert 5 to reach the purpose of energy dissipating; Emergency Gate 3 is an open mode when flat, because its use is fewer, inspection switch 31 is located on the dam body.
Establish extract duct 21 on the hemispherical shell 2, internal gas can be got rid of by extract duct 21 when it is discharged water.
As shown in Figure 2, Service gate 4 is located at a hemispherical shell 2 tops, cylindrical tube 42 and water outlet culvert 5 junctions are provided with Emergency Gate, hemispherical shell one side is provided with into people's gate 7, advancing people's gate 7 makes things convenient for the maintainer to enter the inner place under repair of this jettison gear, because its use is less, for reducing the cost of this device, so be located at hemispherical shell one side.
It is low that this automation does not have the water of pressing installation cost, be convenient to realize the target of automatic management of reservoir unmanned and control, current flow into the culvert that discharges water through after this jettison gear energy dissipating smooth-goingly, reduce washing away culvert and downstream river course, simple in structure, be suitable on middle-size and small-size reservoir, using.
