Description
Technical Field
The utility model belongs to rainwater drainage system's design field, concretely relates to rainwater drainage system that gravity flow and forced ventilated combined together that factory used.
Background
At present, two modes are mainly adopted in a rainwater drainage system of a factory: firstly, natural relief elevation difference is adopted for self-flowing discharge; and secondly, forcibly draining water by a drainage pump after the rainwater is collected by the rainwater collection tank. In the first mode, the landform advantages formed by natural environments are mainly utilized, energy consumption is saved, but the method cannot be applied to all the terrain environments in a factory area; and in the second mode, rainwater is collected and then forcibly discharged, so that energy consumption is caused.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome current defect, provide one kind and both can utilize natural relief elevation difference to discharge the rainwater automatically, can collect the back again with the rainwater and force the emission when necessary, move the rainwater drainage system that self-flow and forced drainage combined together that more nimble factory used. In order to solve the problem, the utility model adopts the following technical scheme:
a rainwater drainage system combining self-flowing and forced drainage for a plant area comprises a rainwater collecting pipe and a forced drainage system, wherein a water outlet of the rainwater collecting pipe is provided with a switching valve well, the switching valve well comprises a natural drainage steel plate valve and a rainwater inlet pool steel plate valve, the natural drainage steel plate valve is connected with a natural rainwater outlet of the plant area, and the rainwater inlet pool steel plate valve is connected with the forced drainage system; the forced drainage system comprises a rainwater collecting pool and a plurality of drainage pumps; the drainage pump is connected to a natural river channel through a pipeline; when the water level of the natural river channel is lower than the water outlet, closing the steel plate valve of the rainwater inlet pool, opening the natural discharge steel plate valve, and discharging rainwater to the natural river channel through a natural rainwater discharge port of the plant area; when the water level of the natural river channel is higher than the water outlet, the steel plate valve for natural discharge is closed, the steel plate valve for the rainwater inlet pool is opened, rainwater flows into the rainwater collection pool, and the rainwater is discharged to the natural river channel through the drainage pump when the water level of the rainwater collection pool is high.
Has the advantages that:
the utility model discloses a setting up the switching valve well, both can utilizing natural fall to arrange water to natural river course, reduce drain pump forced drainage operating duration, practice thrift the electric energy, can start forced drainage system again when needing, be unlikely to cause the rainwater to flow backward.
Drawings
The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description serve to explain the invention and not to limit the invention. In the drawings:
fig. 1 is a schematic flow diagram of the gravity flow system of the present invention;
fig. 2 is a schematic flow chart of the forced exhaust system of the present invention.
Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
As shown in fig. 1-2, the embodiment discloses a rainwater drainage system combining self-flowing and forced drainage for a plant area, the drainage system comprises a rainwater collection pipe 1 and a forced drainage system, a water outlet 11 of the rainwater collection pipe 1 is provided with a switching valve well, the switching valve well comprises a natural drainage steel plate valve 4 and a rainwater inlet pool steel plate valve 3, the natural drainage steel plate valve 3 is connected with a natural rainwater discharge port 2 of the plant area (i.e. self-flowing drainage caused by a natural terrain elevation difference of the plant area), and the rainwater inlet pool steel plate valve 4 is connected with the forced drainage system; the forced drainage system comprises a rainwater collecting pool 5 and a plurality of drainage pumps 6; the drainage pump 6 is connected to a natural river channel through a pipeline; when the water level of the natural river channel is lower than the water outlet 11, closing the steel plate valve 3 of the rainwater inlet pool, opening the natural discharge steel plate valve 4, and discharging rainwater to the natural river channel through the natural rainwater discharge port 2 of the plant area; when nature river course water level is higher than outlet 11, close nature emission steel sheet valve 4, open into rainwater pond steel sheet valve 3, rainwater flows into rainwater collecting tank 5, drains to nature river course through drain pump 6 when 5 water levels of rainwater collecting tank are high.
As shown in figure 1, when in use, the elevation of the drainage port 11 of the rainwater collection pipe 1 is designed as a reference point, and the water level of a nearby natural river channel is found to be-1.55 m through measurement and comparison. At the moment, the water level of the natural river channel is lower than the height of the water outlet 11, the steel plate valve 3 of the rainwater inlet pool is closed, the steel plate valve 4 of the natural drainage pool is opened, and rainwater automatically flows and drains to the natural river channel.
As shown in fig. 2, the elevation of the drainage port 11 of the rainwater collection pipe 1 is designed as a reference point, and the water level of a nearby natural river is 1m through measurement and comparison. At the moment, the water level of the natural river channel is higher than the height of the water outlet 11, the natural discharge steel plate valve 4 is closed, the forced drainage system is started to open the steel plate valve 3 of the rainwater inlet pool, rainwater flows into the rainwater collecting pool 5, and the rainwater is forcibly drained to the natural river channel through the drainage pump 6 after the water level of the rainwater collecting pool 5 exceeds 1 m.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
