the device comprises a drainage well 1, a well cover frame 2, a well cover frame 3, a well cover 4, a grid rail 5, a filter screen 6, a reinforcing rod 7, a supporting block 8, a rotating wheel 9, a baffle plate 10 and a hanging ring.

Detailed Description

The utility model discloses a municipal works rainwater drainage well, specific use is at the drainage well of road tooth lateral wall that says so, and this drainage well passes through institutional advancement, increases the filter screen and can make the water inlet reduce the risk that is blockked up, and the filter screen needs regularly clearance. The present invention will be described in further detail with reference to the following drawings and specific embodiments:

as shown in figures 1 and 2, the municipal engineering rainwater drainage well is based on the existing drainage well structure, is arranged at the position of a road kerb and mainly comprises a square drainage well 1, and the lower end of the drainage well 1 is communicated with a drainage channel. Be provided with well lid frame 2 in the upper end of drainage well 1, can dismantle at the up end of well lid frame 2 and be provided with well lid 3. The drainage well is a brick-concrete structure below the ground, and the well cover frame 2 is made of metal material such as cast iron.

A water inlet is arranged on one side of the well cover frame 2 facing the road. The utility model is different from the prior art, change vertical railing pole for horizontal railing pole 4. Because the distance between the vertical bars pole is too near and stops debris easily, makes debris gather in water inlet department, and change into horizontal bars pole 4 back, along with the change of water level, debris can always follow and pass between the different bars pole 4 and get into the drainage well, can not plug up the water inlet.

As sundries can enter the inverted drainage well, but the sundries cannot enter the drainage pipeline, the filter screen 5 is arranged on the well wall below the water inlet of the drainage well, and the filter screen 5 used at the position is a conventional screen mesh formed by welding criss-cross screen meshes. As shown in fig. 1 and 3, the filter screen 5 is disposed obliquely, and one end of the filter screen 5 at the water inlet is a higher end, and the other end is a lower end. The impurities fall onto the surface of the filter screen 5 and can slide from the higher end to the lower end. Further, in order to make debris more smooth and easy landing, the suit sets up a plurality of runners 8 on the net twine, runner 8 can be around axis free rotation, and when debris fell to filter screen 5 on the surface, debris can follow the eminence landing to the low of filter screen 5 under the action of gravity and because runner 8's rotation. The inclination angle of the filter screen 5 is required to ensure that the sundries can smoothly slide down, and is generally controlled to be more than 20 degrees, and the best angle is 45 degrees.

The utility model provides a filter screen 5 sets up on the inner wall of drainage well 1, and filter screen 5 is located below the water inlet, and the higher one end of general filter screen 5 is apart from outlet 15 ~ 30 cm. After the filter screen 5 is used for a period of time, particularly after heavy rain, more sundries may be accumulated and need to be taken out for cleaning. In order to facilitate the installation and the taking and placing of the filter screen 5, the filter screen 5 is installed on the inner wall of the drainage well 1 in an erecting mode. Specifically, strip-shaped reinforcing rods 6 are fixedly arranged at two opposite high and low ends of the filter screen 5 and two inclined ends of the filter screen; meanwhile, supporting blocks 7 for supporting the reinforcing rods 6 are arranged at corresponding positions on two sides of the well wall, the heights of the two supporting blocks 7 are different so as to enable the filter screen 5 to be in an inclined state, and the supporting blocks 7 on the water inlet side are higher. The filter screen 5 is arranged at the upper end of the supporting block 7 by placing. The four reinforcing rods 6 form a frame structure, and the overall strength of the filter screen 5 can be improved. The inclined arrangement of the filter screen 5 is beneficial to the falling of sundries, and meanwhile, the lower end can be provided with a sufficient space for accommodating the sundries. It is known that when rainwater is discharged from a water inlet to a drain well, the rainwater directly drops on a substrate without being sprayed. Therefore, as long as one section of the filter screen 5 close to the water inlet part is not covered by sundries, smooth falling of rainwater can be ensured, and the inclined filter screen can contain more sundries.

The utility model provides a lower one end of filter screen 5 is used for holding gathering debris, so still set up baffle 9 on its upper surface usually, also can also set up the baffle at the up end on the limit of two slopes, forms a three-sided closed one side open-ended structure.

The filter screen 5 in the drainage well 1 needs to be cleaned regularly and needs to be taken out when being cleaned. In order to take out the filter screen 5 conveniently, the upper surface of the outer edge positions of the two inclined ends is provided with hanging rings 10, and each side is provided with at least two hanging rings 10. When the filter screen 5 is taken out, the filter screen 5 is taken out by hooking the hanging ring 10 with a hook. As shown in fig. 3.

The utility model discloses in, debris fall to the filter screen 5 surfaces of slope, can fall under the action of gravity, but because the existence unloading effect of frictional force is not obvious, so be provided with the contact of runner 8, runner 8's slip makes the debris unloading, especially makes the leaf whereabouts. In a particular implementation, adjacent wheels 8 are arranged with transverse wires and longitudinal wires spaced apart. For example, the adjacent rotating wheels 6 can be provided with 6-12 mesh wires at intervals.

This drainage well in use can contact more rainwater, consequently, chooses for use runner 8 to be the sleeve that rigid plastic made, runner 8 just can not have rust phenomenon like this to plastics are low as the raw materials cost. And a through slit is provided in the side wall of the sleeve. In order to facilitate the mounting of the sleeve to the mesh to form the wheel 8, it is necessary to provide a through slot in the side wall of the sleeve, and the sleeve is sawn with a thin saw blade to form the slot, which is small. And because runner 8 is made for plastics, has certain plastic elasticity, exerts external force and can expand the gap a little to can be with runner 8 suit to the net silk on, this gap can be in almost closed state again under self elastic action after removing external force, runner 8 can not drop from the net silk.

The utility model discloses a water inlet at the drainage shaft sets up horizontal bars pole, sets up filter unit simultaneously in the drainage shaft, can make debris not blocked up at the water inlet, and can enter into the drainage shaft and be intercepted by filter unit, has avoided the water inlet to be blocked up the phenomenon that influences the drainage. Through setting up the filter screen slope of filter unit, the cooperation sets up the runner simultaneously, can make debris landing to the lower one end of keeping away from the water inlet, makes the rainwater get into the drainage from the water inlet and can follow closely the entrance point after intaking and fall to the drainage pipe in. Compared with the drainage well used at present, the drainage well has the advantages that functional parts are increased, but the risk of blockage by sundries can be reduced, and good drainage in rainy weather can be guaranteed as much as possible.
