Definitions
- the present invention relates to an ecological system designed to maintain the environment free from the insects and other animals present in drainpipes by preventing their rise through the drainpipes of hydraulic installations in building industry, such as sanitary fittings and road installations, i.e. manholes.
- the system according to the present invention provides an integral solution by means of a new siphon apparatus characterised by the presence of an obstruction float closing the internal space of the drainpipe, which is raised by water, occupying an upper internal part of non-interference of the siphon, and then brought again to the initial position when water ends, closing the drainpipe from the inside again.
- the system according to the present invention comprises a siphon apparatus in which wastewater goes through an inlet (1) and a water stagnation seat (2) causing the rising, in a chamber (3) above, of the obstruction float (4) that closes the access to the stagnation seat (2) on the drain side, and exits through an outlet (5), bringing the obstruction float (4) back in closed position to prevent the passage of insects and other animals from the bottom of the drainpipe through the immersed section of the stagnation seat (2).
- the lower annular section (6) of the cylindrical obstruction float (4) is provided with a parallel equidistant series of slots (7) for the passage of air bubbles.
- the obstruction float with chamber (3) is formed by a coaxial cylindrical body (8) with flat end
- the retaining body (10) with chamber (3) comprises opposite sloping tapered ends (1 1 and 12) leading to the upper ascending limit (13) and lower descending limit (14) of a spherical obstruction float (4).
- the siphon bottom is provided with an inspection plug (15) with ring.
- a manhole is provided with a siphon apparatus with retaining body (16), grid (17) stagnation tank (18), tank supports (19) and obstruction float (4) with square base with central opening for the vertical movement of the central structure (20) in order to close the access to the stagnation tank (18).
- Fig. 1 and 2 show a siphon apparatus for building industry with cylindrical obstruction float (4) which moves in vertical direction inside the coaxial cylindrical body (8) with flat end (9).
- Fig. 1 is a longitudinal cross-section of the apparatus according to the present invention in idle state with the obstruction float (4) preventing the access from the outlet (5) to the water stagnation seat (2).
- the figure shows an insect (21), whose rise is prevented by the obstruction float (4).
- Fig. 2 is a transversal cross-section of the same apparatus in idle state.
- Fig. 3 is a longitudinal cross-section of the same apparatus inturbulence state due to the passage of wastewater.
- the obstruction float (4) has reached the upper limit (9) of the chamber (3) to drain wastewater through the outlet (5).
- Fig. 4 is a transversal cross-section of the same apparatus in turbulence state.
- Fig. 5 is a perspective view of the apparatus showing the position of the obstruction float (4) in idle state.
- Fig. 6 is a view of the obstruction float (4) with lower slots (7) on the annular section (6) used in the embodiment according to the present invention.
- FIG. 7 is a perspective view of the apparatus showing the position of the obstruction float (4) during the passage of wastewater.
- Drawing 3 shows an embodiment of the siphon apparatus with obstruction float (4) moving in chamber (3) with sloping tapered ends (1 1 and 12) with upper ascending limit (13) and lower descending limit (14).
- Fig. 8 is a longitudinal cross-section of the apparatus in idle state.
- Fig. 9 is a transversal cross-section of the apparatus in idle state.
- Fig. 10 is a longitudinal cross-section of the apparatus in turbulence state due to the passage of wastewater.
- Fig. 1 1 is a transversal cross-section of the apparatus in turbulence state.
- Drawing 4 shows the siphon apparatus for road installations.
- Fig. 12 is a longitudinal cross-section of the apparatus in idle state.
- Fig. 13 is a transversal A-A' cross-section of the apparatus in idle state.
- Fig. 14 is a longitudinal cross-section of the apparatus in turbulence state.
- Fig. 15 is a transversal cross-section showing the non-interference of the obstruction float (4).
- Fig. 16 is a longitudinal cross-section of the apparatus in idle state.
- Fig. 17 is a transversal B-B' cross-section of the apparatus in idle state.
- the shape of the components, the materials etc. may be subject to change as required for specific applications.
