Technical Field

The invention belongs to the field of sponge city construction, and particularly relates to a water storage and drainage integrated water permeable brick for a sponge city.

Background

The sponge city is through the mode of low influence development, realizes urban rainwater system construction, reaches the time of raining and absorbs water, retaining, infiltration, water purification, releases the water of storage and utilizes when needing, makes the purpose that the rainwater can freely migrate in the city, and wherein, sponge city has played key effect in the aspect of reducing ponding, preventing waterlogging and alleviating heat island effect with the brick that permeates water.

Most of the traditional sponge city water permeable bricks are simple in structure, the water storage and drainage capacity of the road surface can be improved to a small extent, the water storage or drainage of the traditional sponge city water permeable bricks cannot be changed according to the rainfall, and good water storage and drainage effects are difficult to achieve; the regional temperature that the flow of people is great in the city is higher, and the rainwater evaporation rate of piling up in the brick that permeates water now is fixed, can't change according to geographical position's difference, and the cooling radiating effect is relatively poor.

Therefore, the sponge city water storage and drainage integrated water permeable brick is provided to solve the problems.

Disclosure of Invention

The invention aims to solve the problems of poor water storage, drainage and heat dissipation effects, and provides a water storage and drainage integrated water permeable brick for a sponge city, which can adjust a water storage and drainage mode according to rainfall and has a good heat dissipation effect.

In order to achieve the purpose, the invention adopts the following technical scheme: a water storage and drainage integrated water permeable brick for a sponge city comprises a brick body, wherein a water storage cavity is arranged in the brick body, a plurality of water inlet holes penetrating through the brick body are formed in the top surface of the water storage cavity, a drainage groove is formed in the side wall of the water storage cavity, two drainage holes penetrating through the brick body are formed in the bottom of the drainage groove, a movable plate is connected to the side wall of the brick body in a sealing and sliding mode, a sleeve is fixedly connected to the inner bottom surface of the water storage cavity, the upper end of the sleeve penetrates through the movable plate and is movably connected with the movable plate, two permanent magnetic sheets are fixedly connected to the lower surface of the movable plate, a magnet sheet is fixedly connected to the inner bottom surface of the water storage cavity, the permanent magnetic sheets and the magnet sheet repel each other in the same pole, an upwardly arched flexible pedal is fixedly connected to the upper surface of the brick body, a threaded rod is rotatably connected to, the lower end of the threaded rod is fixedly connected with the inner bottom surface of the brick body through a return spring, and the threaded rod is fixedly sleeved with a fan.

The invention has the beneficial effects that: when the rainfall is small, the amount of rainwater entering the brick body is small, under the action of magnetic force, the magnet pieces generate repulsive force to the permanent magnet pieces, the movable plate floats above the drainage groove, and the movable plate is sealed with the side wall of the water storage cavity, so that rainwater is completely stored in the brick body, and the water storage capacity of the brick body is improved.

When rainfall is great, the rainfall amount of accumulating above the movable plate is more, under the action of gravity, the movable plate is driven to move downwards to the drainage groove, rainwater in the brick body can flow to the drainage hole through the drainage groove and permeate into soil below the brick body, the drainage capacity of the brick body is guaranteed, the water storage state and the drainage state can be switched according to the rainfall amount, the utilization rate of the rainwater is improved, a good sponge effect is achieved, and the heat island effect of a city is favorably relieved.

When the weather is hotter, the rainwater that continues in the brick body slowly evaporates, then the rainwater volume on the fly leaf reduces gradually, and the rainwater gravity that the fly leaf bore slowly reduces, then under the repulsion effect of magnet piece and permanent magnetism piece, slowly promotes the fly leaf rebound, makes the last liquid level of rainwater be in higher position all the time, has guaranteed the evaporation rate of rainwater, has guaranteed its cooling effect.

The pedestrian is when the brick body top, tramples flexible pedal, promote flexible pedal then and drive the threaded rod and move down, because of the unable rotation of sleeve pipe, then the threaded rod drives the fan and rotates, the wind that the fan rises blows to the rainwater surface of impounding in the retaining intracavity, because of the liquid surface medium velocity of flow is faster, liquid evaporation rate is faster, the evaporation rate of the rainwater of accelerating then, the great region of pedestrian flow in the city, flexible pedal is trampled to the pedestrian is frequent, the cooling effect of the brick that permeates water has further been improved.

As preferred, the upper surface of the brick body is equipped with a plurality of water catch bowl, the water catch bowl is the bowl dress setting of undercut, the inlet opening sets up in the bottom of inlet opening, and during the rainfall, in the rainwater can advance the entering water catch bowl, the rethread inlet opening gets into in the brick body, is favorable to the collection of brick body surface rainwater, and inside sunken water catch bowl has increased the effective area of contact of brick body upper surface, when having reduced the rainwater that falls, pedestrian or vehicle are through taking place water film effect, take place dangerous possibility.

Preferably, the side wall of the water inlet hole is fixedly provided with a filter screen, so that sundries carried in rainwater can be filtered, and blockage in the brick body is prevented.

Preferably, the drainage holes are arranged in a semicircular arc shape, and the two drainage holes are symmetrical about the central axis of the brick body, so that the effect of uniform and rapid drainage is achieved.

Preferably, a first through hole is formed in the movable plate, a sealing plate is connected to the upper surface of the movable plate in a sliding manner, a second through hole is formed in the sealing plate, a coil spring is sleeved outside the sealing plate, an inner ring of the coil spring is fixedly connected with the sealing plate, an outer ring of the coil spring is fixedly connected with the movable plate, a water seepage hole matched with the first through hole is formed in the inner bottom surface of the water storage cavity, when the brick body is full of rainwater when the rainfall is extremely high, a large amount of rainwater further extrudes the movable plate to extrude the movable plate to a lower position under the action of gravity, at the moment, the repulsion force is larger because the permanent magnet pieces are closer to the magnet pieces, and the magnet pieces with the same magnetic poles cannot be in positive opposition, the permanent magnet pieces drive the movable plate to be twisted by a certain angle under the action of magnetic force, so that the first through hole is communicated with the second through hole, and then, the drainage of rainwater is accelerated, and excessive rainwater is prevented from being accumulated on the upper surface of the brick body to form a water accumulation pit.
