In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Examples
The automatic drainage device for rainwater in the drainage ditch shown in fig. 1 to 6 comprises a drainage ditch 1, a first cover body, a plurality of drainage ponds 3 and a second cover body.
As shown in fig. 1 and 3, the drainage ditch 1 is provided below the ground and communicates with a rainwater pipe 5. Specifically, the drainage ditch 1 may be formed of a concrete structure. Wherein, a layer structure and the like can be arranged on the ground to meet the use requirements of people, for example, a plastic runway layer is arranged on the ground to form a runway to meet the sports requirements of people. When the raceway is of a ring configuration in a direction parallel to the ground, the gutter 1 is also of a ring configuration in a direction parallel to the ground as shown in fig. 4. Of course, when the raceway is of a rectangular configuration in the direction parallel to the ground surface, the drainage ditch 1 is also of a rectangular configuration in the direction parallel to the ground surface, and so on, i.e., the configuration of the drainage ditch 1 in the direction parallel to the ground surface is the same as the configuration of the raceway in the direction parallel to the ground surface. Specifically, the bottom wall surface of the drainage ditch 1 is a sloping surface which is inclined downward in the discharge direction in which rainwater is collected to the rainwater pipe 5, i.e., a down slope in the direction indicated by an arrow in fig. 4. It should be noted that since the slope surface has an extremely small slope, the bottom wall surface of the drain 1 in fig. 1 is similar to a plane, and actually, the slope surface has an extremely small slope. Due to the slope surface arrangement, the flowing speed of rainwater in the drainage ditch 1 can be improved, and the condition that the rainwater is accumulated and is not drained in time is avoided.
The first cover body in this embodiment covers the drainage ditch 1, and the first cover body is provided with a drainage outlet 23, so that rainwater can pass through the ground and then enter the drainage ditch 1 through the drainage outlet 23. As shown in fig. 1 to 3, the first cover body includes a first fixed cover body 21 and a first movable cover body 22, the first movable cover body 22 covers the top of the discarding pool 3, the first fixed cover body 21 and the discarding pool 3 are arranged in a staggered manner, and the number of the water outlets 23 on the first fixed cover body 21 is smaller than the number of the water outlets 23 on the first movable cover body 22. The clearance to escape canal 1, abandon pond 3 can be accomplished to the first removal lid 22 of accessible removal, can improve cleaning efficiency.
Specifically, four first movable cover bodies 22 are disposed above one discarding pool 3 in fig. 1, two water discharge ports 23 are disposed on the first movable cover bodies 22 in fig. 6, one first fixed cover body 21 is disposed above between two adjacent discarding pools 3, and one water discharge port 23 is disposed on the first fixed cover body 21 in fig. 5. The number of the first movable cover 22 and the first fixed cover 21 is set according to the respective sizes. Wherein the first fixed cover body 21 may be adhered to the side wall of the drainage ditch 1 by, for example, concrete, and the first movable cover body 22 is overlapped on the side wall of the drainage ditch 1. During rainfall, rainwater enters the drainage ditch 1 through the drainage port 23, the area of rainwater runoff entering the drainage ditch 1 is increased by increasing the number of the drainage ports 23, and the rainwater runoff on the ground is regulated and stored more quickly.
As shown in fig. 1, the second cover body is provided between the drainage ditch 1 and the discarding pool 3 and shields a part of the communication port of the discarding pool 3. Wherein the abandoning tank 3 is communicated with the drainage ditch 1 through a communication port of the abandoning tank 3. Specifically, the second cover body includes a second cover body 41 and an oil-contaminated filter member 42, the second cover body 41 is rotatably disposed, for example, the second cover body 41 is rotatably connected to the bottom wall of the drainage ditch 1, and the oil-contaminated filter member 42 is disposed at an end portion of the second cover body 41 and protrudes toward the discarding pool 3. As an alternative embodiment, the second cover body 41 is rotatably connected to a moving member, and the moving member is slidably connected to the bottom wall of the drainage ditch 1. As an alternative embodiment, the second cover body 41 is slidably attached to the bottom wall of the drainage ditch 1.
When the water level of the rainwater in the abandoning pond 3 is too high when getting into, greasy dirt filter piece 42 can block to abandon greasy dirt and impurity that brings when the rainwater passes through the runway in the pond 3 to avoid getting back to escape canal 1 and polluted middle stage, later stage rainwater, and abandon the intercommunication mouth in pond 3 through rotating second lid body 41 in order not to shelter from, be convenient for clear up greasy dirt, impurity.
The working process of the automatic drainage ditch rainwater discarding device comprises the following steps: during the rainfall, the initial stage rainwater passes through outlet 23 and gets into escape canal 1, and the rethread escape canal 1 gets into abandons to collect and fill gradually in removing pond 3 and abandons except that pond 3, and other rainwater of later middle period, later stage rainwater are direct to collect to downspout 5 through escape canal 1, and downspout 5 can be connected to other devices and spray cyclic utilization such as watering. When the drainage ditch 1 and the abandon tank 3 need to be cleaned, the first movable cover body 22 and the second cover body 41 can be moved to clean the drainage ditch.
According to the automatic drainage ditch rainwater discarding device, initial rainwater is collected through the discarding pool 3, the initial rainwater automatically settles, filters and separates in the discarding pool 3 under the action of self gravity of impurities in the initial rainwater, the initial rainwater with poor water quality is automatically intercepted in the rainfall process, and the middle-stage rainwater and the later-stage rainwater can be directly drained into the rainwater pipe 5 for recycling, so that the rainwater can be recycled; the device only needs to regularly remove the garbage pollutants and impurities in the discarding pool 3, so that the problem that the filtering service life of a filtering component in the prior art is influenced by the adsorption of the impurities is solved, the filtering cost is reduced, and the rainwater can be recycled; and abandon the adjustable initial stage rainwater that holds in pond, control and get into escape canal 1 and collect the flow to rainwater pipe 5 in to the rivers stability in the rainwater pipe 5 is guaranteed.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
