Abstract
The invention discloses a simple backflow prevention device for an inspection well. The simple backflow prevention device for the inspection well comprises a fixed frame, two backflow prevention plates and floats. The fixed frame is fixed on the wall of the inspection well; the split backflow prevention plates are connected to the lower surface of the fixed frame by hinges so as to ensure that the split backflow prevention plates are enabled to be only unidirectionally opened downwards; and the floats are fixed to the bottom surfaces of the backflow prevention plates so as to ensure that when the water level is risen, the floats float to close the backflow prevention plates upwards and water in the inspection well is prevented from flowing back to the earth surface. The simple backflow prevention device for the inspection well has a simple structure, is low in manufacturing cost and has reliable functions.
Description
Technical field
The present invention relates to the Municipal Drainage Engineering field, particularly the inspection shaft water discharge technology.
Background technology
Inspection shaft pours in down a chimney phenomenon as the necessary means of street drainage but can't solve to face along sewer at present.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of Simple anti-backflow device for inspection wells, prevents that the street rainwater from pouring in down a chimney.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: comprise fixed mount, two blocks of antireflux plates and two floats.Described fixed mount is annular, and its soffit is connected with two antireflux plates of splitting by hinge, guarantees that described antireflux plate opens downwards, float is fixed in the bottom surface of antireflux plate, when guaranteed water level goes up the antireflux plate is closed, the sealing well head, water is counter in the prevention inspection shaft flows.Simple in structure, the low cost of manufacture of the present invention, reliable in function.
Description of drawings
Fig. 1 is a kind of Simple anti-backflow device for inspection wells antapical view of the present invention
Fig. 2 is a kind of Simple anti-backflow device for inspection wells apical view of the present invention
The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments:
A kind of Simple anti-backflow device for inspection wells shown in Figure 1 comprises fixed mount 1, antireflux plate 2,3, float 4.Described fixed mount 1, described fixed mount is annular, preferred Q-RING, the antireflux plate 2,3 that fixed mount 1 soffit is connected through the hinge two and splits, assurance antireflux plate is opened downwards, described float, described float 4,5, can be fixed in the antireflux plate below, when the inspection shaft water level goes up, it floats closes antireflux plate 2,3, stops the anti-earth's surface that flow to of inspection shaft water.
Mounting means of the present invention is as follows: apparatus of the present invention are fixed on the inspection shaft wall by fixed mount 1, and two blocks of antireflux plates 2,3 are hinged through the hinge to fixed mount 1 soffit, float 2,3 be fixed in antireflux plate 3,4 below.
Claims (2)
