Description
Technical field
The utility model relates to the gate structure in a kind of hydraulic engineering, particularly a kind of buoyancy lock gate for flood protection.
Background technology
Lock gate for flood protection in the existing hydraulic engineering all is an one, when needs discharge water downstream, just need upwards lift whole gate, and water can flow through below gate.But, be difficult to the water level of upstream is controlled at desired height because the source, water source of upstream constantly adds to the gate place.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of buoyancy lock gate for flood protection to be provided, it have simple in structure, open rapidly, the utilization rate advantages of higher.
The technical scheme that realizes above-mentioned purpose is: a kind of buoyancy lock gate for flood protection, comprise the flood-control wall between the upstream and downstream that is cast in rivers bank or rivers, and described lock gate for flood protection also comprises a cabin body and a floating gate, wherein,
The upper end open of described cabin body reaches all sealings of bottom all around, and it is made by steel material, and it is embedded in the described flood-control wall, and an Inlet and outlet water through hole is offered in the bottom of described cabin body on a side of rivers;
The lower width of described floating gate is greater than the width coupling of upper width and bottom span and described cabin intracoelomic cavity, so that floating gate can slide up and down to be plugged in the body of described cabin, it is made by light material;
Described flood-control wall is offered a water inlet in the mode consistent with the horizontal level of the Inlet and outlet water through hole of described cabin body on the side of rivers bank or upper reaches, and offers an intake tunnel at this water inlet between the Inlet and outlet water through hole of described cabin body; Described flood-control wall is offered an overfall gap at a side roof part of rivers bank or upper reaches, and offers a spilling water passage at this overfall gap between the Inlet and outlet water through hole of described cabin body.
Above-mentioned a kind of buoyancy lock gate for flood protection, wherein, the top in the body of described cabin also is provided with limited block, breaks away from described cabin body to limit described floating gate.
Above-mentioned a kind of buoyancy lock gate for flood protection, wherein, the surface of described floating gate scribbles a compacted zone, and the material of this compacted zone is water sieve Song or epoxy resin.
The technical scheme of a kind of buoyancy lock gate for flood protection of the present utility model adopts flood-control wall, cabin body and floating gate three structure combining, and floating gate can move up and down under the effect of hydraulic pressure, thereby reaches the purpose of control upper pond level.It has simple in structure, open rapidly, the utilization rate advantages of higher.
Description of drawings
Fig. 1 is the structural representation of buoyancy lock gate for flood protection of the present utility model.
The specific embodiment
In order to understand the technical solution of the utility model better, below by embodiment particularly and be described in detail in conjunction with the accompanying drawings:
See also Fig. 1, buoyancy lock gate for flood protection of the present utility model comprises flood-control wall 1, a cabin body 2 and a floating gate 3, wherein,
Flood-control wall 1 can be cemented rock body of wall or steel bar concrete body of wall, and it is cast between the upstream and downstream of rivers bank or rivers;
Floating gate 3 is made by light material, and its surface scribbles a compacted zone, and the material of this compacted zone is water sieve Song or epoxy resin; The lower width of floating gate 3 is greater than the width coupling of upper width and bottom span and cabin body 2 inner chambers, so that in the cabin body 2 that floating gate 3 can slide up and down to be plugged on, floating gate is made guiding and limited its escape vehicle body 2 by limited block 4;
Flood-control wall 1 is offered a water inlet 10 in the mode consistent with the horizontal level of the Inlet and outlet water through hole 20 of cabin body 2 on a side of rivers bank or upper reaches, and offers an intake tunnel 11 at this water inlet 10 between the Inlet and outlet water through hole 20 of cabin body 2; Flood-control wall 1 is offered an overfall gap 12 at a side roof part of rivers bank or upper reaches, and offers a spilling water passage 13 at this overfall gap 12 between the Inlet and outlet water through hole 20 of cabin body 2.
The operating principle of buoyancy lock gate for flood protection of the present utility model is:
When the water level rise of rivers or upper reaches surpasses the water inlet 10 of flood-control wall 1, the Inlet and outlet water through hole 20 of cabin body 2 bottoms begins to intake 5 by intake tunnel 11, when the gravity of hydraulic pressure greater than floating gate 3, floating gate 3 in cabin body 2 slowly upwards floats, after cabin body 2 is full of water, the limited block 4 on the bottom of floating gate 3 come-up tops to the cabin body 2, floating gate 3 is the highest to float the upper height that exceeds floating gate 3 than flood-control wall 1.When the drawdown of rivers or upper reaches, water in the cabin body 2 slowly descends, because the hydrostatic pressure of the water inlet 10 of flood-control wall 1 is greater than the pressure of overfall gap 12, water 5 overflows from overfall gap 12 by spilling water passage 13 from Inlet and outlet water through hole 20, water level outside flood-control wall 1 water inlet 10 or below, floating gate 3 returns to original position.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
