Abstract
Surface water taking entrance gate safeguard structure is related to water power hydraulic engineering metal structure technical field, more particularly, to a kind of surface water taking entrance gate safeguard structure.The surface water taking entrance gate safeguard structure of the utility model, the top of the gate of surface water intaking apparatus three-port structure front end horizontal inlet is set, it is characterized in that the structure includes shield and lifting lug, shield is in triangular shape, it is arranged at the top of gate, forward and backward edge is concordant with gate, and the side steel plate at both ends extends to upper edge at the top of gate, and safe distance is reserved between gate recess, lifting lug is arranged at the top of shield.The surface layer automatically taking water of the utility model is oriented to and scraping dirt panel assembly, design science, structurally reasonable, compared with other automatic water intaking devices, can effectively prevent silt and dirt accumulation at the top of gate, and have protective effect to gate.
Description
Technical field
The utility model relates to water power hydraulic engineering metal structure technical fields, more particularly, to a kind of surface water taking import
Gate safeguard structure.
Background technique
The development and utilization of water resource should not only meet the quantitative requirement of water, should also meet the quality requirement of water, and people want section
Ground is learned using the water in reservoir, it is necessary to ecological dispatching be carried out to reservoir, that is, the good superficial water of matter of fetching water from reservoir, i.e.,
Surface water taking.
According to reservoir stratification characteristic, reservoir is divided into stratotype, osculant, three kinds of mixed type.Large and middle reservoirs are mostly stratification
Type reservoir, i.e., the temperature of water, turbidity layer distributed in reservoir.Research shows that: it can with surface layer warm-water irrigation deeper cold water irrigation
Make increasing production of rice 30%, using containing planktonic organism it is more superficial water power generation meeting so that in the river of tens kilometers of downstream fishery subtract
It produces, is not only to meet quantitative requirement just, it is necessary to meet quality requirement, section as can be seen from above to the utilization of reservoir water
Ground is learned using the water in reservoir, must just carry out ecological dispatching to reservoir, in order to obtain superficial water from reservoir, phase in recent years
Some surface water taking facilities should have been built up.
Hydraulic surface layer automatic water intaking device, which is utilized, provides buoyancy with the buoyancy tank of SEA LEVEL VARIATION automatic lifting, drives cartridge type folded
Set intake pipe is pulled up or is nested downwards, superficial water is introduced intake, to achieve the purpose that superficial water can be taken automatically.Surface layer
In the process of running, if the nestable intake pipe of cartridge type card resistance occurs and takes less than water, there is water inside and outside intake pipe in automatic water intaking device
Pressure difference is excessive, can damage to intake pipe；Or water fetching device is arranged by structure and operating water level is limited, intake pipe is minimum
It is limited that position is set, needs to fetch water by other channels.For this purpose, the bottom of water fetching device is arranged to three-port structure, three-port structure
Front end setting trash rack and main gate.Emergency water intaking when card resistance occurs in intake pipe when main gate can be used for high water level and
Water intaking when low water level.Because three-port structure is completely set up under water, and the gate slot of gate is arranged on steel structure support column,
Silt, dirt accumulation inevitably are had at the top of gate, influences the operation of gate, serious situation is even stuck by gate,
It can not lift.
To solve the above contradiction, the utility model proposes a kind of surface layer automatically taking water entrance gate safeguard structure, the structures
Silt and dirt accumulation can be prevented on gate door top, gate is protected.
Summary of the invention
The purpose of the utility model is to overcome deficiency in the prior art, a kind of design science, structurally reasonable is provided
Surface layer automatically taking water entrance gate safeguard structure.
The surface water taking entrance gate safeguard structure of the utility model is arranged in surface water intaking apparatus three-port structure front end water
The top of the gate of flat import, it is characterised in that the structure includes shield and lifting lug, and shield is in triangular shape, is arranged in gate
Top, forward and backward edge is concordant with gate, and the side steel plate at both ends extends to upper edge at the top of gate, and pre- between gate recess
Safe distance is stayed, lifting lug is arranged at the top of shield.
Its top of the shield is the inclined-plane of inclined downstream, and middle position is provided with through-hole, convenient for the branch of gate
Dagger passes through.
The lifting lug is two, is symmetrical set at the top of shield.
The shield is connect using activity or fixed form with gate, and wherein manner is that steel is reserved on lifting lug
Cord, under the drive of wirerope, shield does lifting along support column track or decentralization moves；Fixed form be by pull rod or
Shield is fixed at the top of gate by person's bolt, and shield is moved with gate.
The surface layer automatically taking water of the utility model is oriented to and scraping dirt panel assembly, design science, structurally reasonable, automatic with other
Water fetching device is compared, and can effectively prevent silt and dirt accumulation at the top of gate, and has protective effect to gate.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Wherein, shield 1, lifting lug 2.
Specific embodiment
Embodiment 1: a kind of surface water taking entrance gate safeguard structure is arranged in surface water intaking apparatus three-port structure front end water
The top of the gate of flat import, it is characterised in that the structure includes shield 1 and lifting lug 2, and shield 1 is in triangular shape, and setting exists
At the top of gate, forward and backward edge is concordant with gate, and the side steel plate at both ends extends to and goes up edge at the top of gate, and with gate recess it
Between reserve safe distance, the setting of lifting lug 2 is at the top of shield 1.Its top of shield 1 is the inclined-plane of inclined downstream, interposition
It installs and is equipped with through-hole, passed through convenient for the support column of gate.Lifting lug 2 is two, is symmetrical set at 1 top of shield.Protection
Cover 1 is connect using activity or fixed form with gate, and wherein manner is that wirerope is reserved on lifting lug 2, in wirerope
Under drive, shield 1 does lifting along support column track or decentralization moves；Fixed form is by pull rod or bolt by shield
1 is fixed at the top of gate, and shield 1 is moved with gate.
