Detailed Description

The following describes embodiments of the present invention with reference to the accompanying drawings.

As shown in fig. 1 to 5, the present invention provides a specific embodiment of a rainwater drainage well. The rainwater discarding well comprises a cylindrical well body 1, a well cover 6 is detachably arranged at the upper end opening of the well body 1, the well body 1 is provided with a water inlet 13, a water outlet 14 and a sewage discharge outlet 15, a partition plate 2 is horizontally arranged in the well body 1, the partition plate 2 divides an inner cavity of the well body 1 into a filtering cavity 11 and a discarding cavity 12 which are distributed up and down, the water inlet 13 and the water outlet 14 are communicated with the filtering cavity 11, the sewage discharge outlet 15 is communicated with the discarding cavity 12, and a rainwater filtering device 3 is further arranged in the filtering cavity 11; the partition plate 2 is provided with a flow abandoning hole 21 for communicating the filter cavity 11 with the flow abandoning cavity 12, a flow locking and abandoning device is further arranged between the filter cavity 11 and the flow abandoning cavity 12, the flow locking and abandoning device comprises a floating ball 41 arranged in the filter cavity 11 and a blocking piece 42 arranged in the flow abandoning cavity 12 and connected with the floating ball 41, and a support 5 for supporting the floating ball 41 to prevent the floating ball 41 from blocking the flow abandoning hole 21 is arranged on the partition plate 2.

When the rainwater discarding well is used, the water inlet 13 is communicated with a drainage system of urban building facilities, the water outlet 14 is communicated with a rainwater collecting device, the sewage outlet 15 is communicated with a urban sewage pipe network, rainwater collected by the drainage system of the urban building facilities in rainy days flows into the well body 1 through the water inlet 13 and then flows out from the water outlet 14 or the sewage outlet 15. Specifically, in the initial stage of use of the rainwater drainage well, the support 5 supports the floating ball 41 to open the drainage hole 21, so that rainwater flowing into the filter chamber 11 flows through the rainwater filter device 3, then enters the drainage chamber 12, and is discharged through the sewage discharge outlet 15, and initial rainwater drainage is completed. After the rainwater discarding well is used for a period of time, the inflow amount of rainwater is greater than the discharge amount, so that the water level in the well body 1 rises, the floating ball 41 rises under the action of buoyancy and drives the plugging piece 42 connected with the floating ball to rise until the plugging piece 42 closes the discarding flow hole 21, and then the rainwater flowing into the filter cavity 11 from the water inlet 13 flows through the rainwater filter device 3 and then is directly discharged through the water outlet 14, so that the later-stage rainwater collection is completed.

As shown in fig. 2 and fig. 3, the bracket 5 is a U-shaped plate which is reversely buckled at the position of the abandoning hole 21, the free end of the U-shaped plate forms an outward-turned installation flange, when the amount of rainwater in the well body 1 is less, the floating ball 41 cannot abut against the abandoning hole 21 under the support of the U-shaped plate, that is, the floating ball 41 cannot block the abandoning hole 21, so that the abandoning hole 21 can be ensured to normally drain water. U-shaped plate support 5's simple structure is comparatively firm after installing division board 2, and is not fragile during the use, and can not influence the area of abandoning the overflowing of discharge orifice 21.

In this embodiment, the water inlet 13 and the water outlet 14 are both disposed on the sidewall of the well body 1 and have the same height.

In this embodiment, the float 41 and the plugging member 42 are connected by a connecting rod 43 passing through the U-shaped plate, and a connecting rod guide cylinder 51 is further disposed on the upper end surface of the U-shaped plate, so that, in use, the float 41 and the plugging member 42 can move vertically up and down along the connecting rod guide cylinder 51 along with the change of the water amount in the well body, thereby opening or closing the discharge hole 21.

In this embodiment, the blocking member 42 is a blocking plate adapted to the size of the discarding orifice 21, and can block the discarding orifice 21 when the blocking plate abuts against the discarding orifice 21. The plugging plate has the advantages of simple structure, convenient installation, small occupied space and better sealing effect when the plugging plate is propped against the flow discarding hole 21.

As shown in fig. 1, 4 and 5, a detachable well cover 6 is arranged on the well body 1, and the rainwater filtering device 3 is a detachable basket grid. The sundries entering the filter cavity 11 can be effectively filtered by utilizing the basket grid, and the sundries with larger volume are prevented from flowing into a rainwater collecting device through the water outlet 14 or flowing into a city sewage pipe network through the sewage discharge port 15. This rainwater abandons a class well when using, if store up more debris in the hand-basket grid, can open well lid 6, take out and clear up the hand-basket grid from filter chamber 11 to guarantee the water-passing effect of hand-basket grid, ensure that this rainwater abandons class well can normal use.

As shown in fig. 1, 4 and 5, the basket grid is placed on the partition plate 2, the basket grid includes a frame 31, a filtering bottom plate 32 and a side wall 33 surrounded by the filtering net, the filtering bottom plate 32 is concave to form a cylinder cover for covering the floating ball 41, and the side wall 33 is provided with an opening adapted to the water inlet 13. The basket grating is directly placed on the partition plate 2, and other structures do not need to be additionally designed for fixing, so that the structure is simple, and the installation and taking are convenient.

As shown in fig. 1, 4 and 5, the filtering bottom plate 32 is disposed at a position higher than the bottom of the frame 31, so that a water gap is formed between the filtering bottom plate 32 and the partition plate 2 when the basket grid is placed on the partition plate 2, and the filtering holes on the filtering bottom plate 32 are not blocked by the partition plate 2, so that the whole filtering bottom plate 32 can pass water when the basket grid is used, that is, the water passing area of the basket grid bottom plate can be ensured, the drainage speed of initial rainwater flow abandoning is ensured, the water abandoning amount is further ensured, and relatively clean rainwater is ensured to be collected.

As shown in fig. 1 and 2, the lower end surface of the partition plate 2 is provided with a fixing bracket 7. The partition plate 2 is fixedly installed by the fixing support 7, so that the fixing support is stable, high in strength and not easy to damage in use.

In other embodiments, the bracket can also be lugs distributed at intervals around the drainage hole and arranged on the upper end surface of the partition plate, and a water passing channel is reserved between two adjacent lugs.

In other embodiments, the water inlet can be arranged on the well cover, and the water outlet is arranged on the side wall of the well body.

In other embodiments, the blocking member may be connected to the bottom of the float ball by a chain.

In other embodiments, the blocking member may be a floating ball, and the volume of the floating ball in the fluid discarding chamber is larger than that of the floating ball in the filtering chamber.

In other embodiments, the rainwater filtering device can include a filter screen which is fixedly and horizontally arranged between the partition plate and the water inlet and a filter screen which is arranged at the water outlet, and when more impurities are accumulated in the filter cavity, the well cover is opened and the impurities are taken out.

In other embodiments, a plurality of protrusions for placing the basket grid can be arranged on the side wall of the well body, wherein the protrusions are arranged at the position higher than the tops of the separation plate and the floating ball and lower than the water inlet.

In other embodiments, radially extending mounting strips may be provided at the edges of the upper end face of the divider plate, the fixing of the divider plate being achieved by mounting the mounting strips to the side walls of the well.
