Abstract
The invention discloses a hydraulic energy dissipation device. The hydraulic energy dissipation device which comprises a base and a case body is arranged inside a pool of an underground drainage system and connected with a drainage pipeline. The case body is divided into an upper portion and a lower portion, the diameter of the lower portion is larger than that of the upper portion, spiral pieces which are arranged around a support arranged inside the case body are divided into big spiral pieces and small spiral pieces, the big spiral pieces are installed on the lower portion of the case body and the small spiral pieces are arranged on the upper portion of the case body, and the size of spiral pieces is matched with the diameter of the case body. The hydraulic energy dissipation device is applicable to reservoirs of urban water supply and drainage stations and sewage pumping stations. The water flows out the case body along the path of spiral pieces after entering the case body. On the one hand, the flow velocity is reduced by the expansion of sectional area of the water flow owing to constant flow rate; on the other hand, the flow direction of the water flow is changed by the design of a spiral structure, finally the water flows to the bottom of the pool along a direction nearly parallel to the bottom, and most impact force is removed, so that energy of the water flow is reduced, and the hydraulic sustainment of the bottom of the pool is decreased.
Description
Technical field
The present invention relates to a kind of hydraulic buffer, refer more particularly to a kind of hydraulic buffer that is applicable to reservoir.
Background technology
In the Urban Underground drainage system, large amount of sewage flows into sewage reservoir through drainage pipe, and basin bottom can be damaged by for a long time impact of current, and especially in the larger situation of displacement, basin bottom will be born huge hydraulic blow; Certainly some good underdrainage systems are also arranged, the engineer considers this point, and pre-embedded steel slab is to keep out water impact bottom reservoir in the building course, and long-term current scour can damage reservoir eventually; For addressing this problem, existing drainage system is transformed obviously unrealistic, so need to provide a kind of device that can effectively weaken streaming potential to alleviate the pressure of reservoir bottom.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of hydraulic buffer simple in structure, easy for installation.
In order to solve the problems of the technologies described above, the invention provides a kind of hydraulic buffer, described hydraulic buffer is provided with pond and drainage pipe, described hydraulic buffer is located in the pond of underdrainage system, and be connected with drainage pipe, described hydraulic buffer comprises base and casing, casing is divided into casing top and lower box structure, the diameter of described lower box is provided with pillar greater than the diameter on casing top in the described casing, is provided with flight around the described pillar, flight is divided into king bolt sheet and minor spiral sheet, described king bolt sheet is located at lower box, and described minor spiral sheet is located at casing top, and described flight size is suitable with box body diameter.
As a further improvement on the present invention, described casing is provided with water inlet, and described water inlet is fixedly connected with drainage pipe.
As a further improvement on the present invention, described base two ends are provided with support, and described support is fixedly connected with the pond.
Adopt said structure, its beneficial effect is: be provided with pillar in the described casing, be provided with flight around the described pillar, flight is divided into king bolt sheet and minor spiral sheet, described king bolt sheet is located at lower box, described minor spiral sheet is located at casing top, and current enter the interior path flow along flight of casing and go out casing, on the one hand, because constant flow, the long-pending enlarged meeting of water flow section slows down flow velocity, and on the other hand, the design of helical structure is so that the flow direction change, finally with almost with at the bottom of direction equal at the bottom of the pond flows to the pond, shed most of impact force, thereby reduced streaming potential, made and bear waterpower at the bottom of the pond and reduce.
Description of drawings
Fig. 1 is the structural representation of hydraulic buffer of the present invention.
Among the figure: 1-pond, 2-drainage pipe, 3-base, 4-casing, 5-pillar, 6-king bolt sheet, 7-minor spiral sheet, 8-water inlet, 9-support.
The specific embodiment
The present invention will be further described in detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of hydraulic buffer, described hydraulic buffer is provided with pond 1 and drainage pipe 2, described hydraulic buffer is located in the pond 1 of underdrainage system, and be connected with drainage pipe 2, described hydraulic buffer comprises base 3 and casing 4, casing 4 is divided into casing top and lower box structure, the diameter of described lower box is provided with pillar 5 greater than the diameter on casing top in the described casing 4, is provided with flight around the described pillar 5, flight is divided into king bolt sheet 6 and minor spiral sheet 7, described king bolt sheet 6 is located at casing 4 bottoms, and described minor spiral sheet 7 is located at casing 4 tops, and described flight size is suitable with casing 4 diameters, described casing 4 is provided with water inlet 8, described water inlet 8 is fixedly connected with drainage pipe 2, and described base 3 two ends are provided with support 9, and described support 9 is fixedly connected with pond 1.
Hydraulic buffer is placed 1 bottom, pond, water inlet 8 and drainage pipe 2 are connected and fixed, again support 9 is fixed in basin bottom, after current enter casing 4 tops, flow along minor spiral sheet 7 directions first, water flow section is long-pending to be enlarged, and reduces a part of potential energy, flows into casing 4 bottoms again, flow along king bolt sheet 6 directions, water flow section is long-pending to be enlarged again, reduces again a part of potential energy, when flowing out casing 4, streaming potential reduces before flowing into casing 4 greatly, and flow direction also almost is parallel to basin bottom to become, and the suffered impact of basin bottom greatly reduces like this, the threat of having avoided the hand water impact to damage.
The present invention is simple in structure, and is easy for installation, and Non-energy-consumption is highly suitable for the reservoir of urban water supply and sewerage, sewage pumping station.Anyly take to be similar to the designed hydraulic buffer of technical characterstic of the present invention and will fall into protection scope of the present invention.
