A kind of low noise artificial waterfall
Technical field
The utility model relates to gardens man-made tourist site technical field, is specifically related to a kind of low noise artificial waterfall.
Background technology
The Along with people's growth in the living standard, local some man-made tourist sites of ornaments such as people can be in the garden, porch, hotel such as artificial waterfall, are built the life idea of a kind of noble elegance, back to nature.Existing artificial waterfall is that molding body is set on the pond, utilizes water pump, water pipe that the water in the pond is extracted into the molding body top, lets current come down in torrents then.The height of molding body is high more, and current come down in torrents surging more, and the noise that sends is big more.Like this, stand in the preceding people that appreciate this man-made tourist site of artificial waterfall and just can't carry out language communication.Therefore, be necessary to reduce the current noise of artificial waterfall, make people both can appreciate this artificial beautiful scenery, can before this artificial beautiful scenery, carry out carefree interchange again, express the impression of oneself.
The utility model content
The purpose of the utility model is to overcome the deficiency of above-mentioned prior art, and a kind of low noise artificial waterfall simple in structure is provided.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of low noise artificial waterfall comprises the pond, is arranged on the molding body on the said pond, also is provided with the flat device on the said pond, and said flat device places the below of the current that slide along molding body.
Said flat device comprises casing, the vibration-damping sheet of vertical array in said casing.
Preferably, said vibration-damping sheet is a sheet.
Preferably, said vibration-damping sheet is netted.
Preferably, said vibration-damping sheet surface is provided with the macromolecule damping layer.
The beneficial effect of the utility model is: 1, set up the flat device in the place that current fall, do not influence former artificial view and reach the reduction anti noise again; 2, the flat apparatus structure is simple, does not need consuming any energy source, low production cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and practical implementation example a kind of low noise artificial waterfall of the utility model is done further explain.
As shown in Figure 1, the low noise artificial waterfall of the utility model comprises pond 1, is arranged on the molding body 2 on the pond.Water in the pond 1 flows to molding body 2 tops through water pump (figure does not show), water pipe (figure does not show) by 1 bottom, pond, and comes down in torrents from molding body 2 tops, forms waterfall.
Place under current come down in torrents is provided with the flat device.Said flat device comprises casing 3, is provided with vertically disposed vibration-damping sheet 4 in the said casing 3.Said vibration-damping sheet 4 is to adopt the high-intensity nonmetal sheet or netted of processing.When current fall, earlier through vibration-damping sheet 4, act on two sides of vibration-damping sheet 4, vibration-damping sheet 4 lateral stressed less like this, laterally just is difficult to produce stronger vibration, reduced the noise that oscillation crosswise produced.Vibration-damping sheet 4 certain rigidity vertically arranged, and the support force of casing 3 is arranged at the bottom, is difficult for producing than strong vibration so vertically go up, vertically noise is also with regard to corresponding reduction.
In order to strengthen effectiveness in vibration suppression; Reduce anti noise thereby strengthen, can also form macromolecule damping layer (figure does not show) at the surface-coated polymer damping material of vibration-damping sheet 4; Thereby consume the part vibration of current when coming down in torrents, further reduce noise.
The flat device can be formed some groups of casings according to the size of the area that falls into water and place and face drowning zone on the pond.
