filter screens are arranged at the water inlet and the side water outlet;
a valve cover which can be opened/closed at one side is hinged on the bottom water outlet; the valve cover is connected with the floating ball through a connecting rope.
The preferred scheme of the rainwater collecting system of the hollow permeable curb of the invention is as follows: the connecting rope can extend to penetrate through the floating ball to be fixed at the inner top of the hollow water-permeable curb.
The preferred scheme of the rainwater collecting system of the hollow permeable curb of the invention is as follows: the top of the rainwater well is provided with a rainwater well cover, and the upper part of the rainwater well cover is covered with a rainwater grate;
the rainwater grate is a filter screen grating cover made of stainless steel, and a spring is arranged below the filter screen grating cover; the lower part of the spring is connected with a movable block; the movable block can be movably embedded in the rainwater well cover.
The preferred scheme of the rainwater collecting system of the hollow permeable curb of the invention is as follows: the rainwater collecting and recycling system comprises a rainwater regulating pool, a submersible pump and an access hole, wherein the rainwater regulating pool is communicated with a bottom water outlet and a rainwater well;
the rainwater regulation pool is communicated with a municipal drainage pipe through an overflow port.
The rainwater adjusting tank is used for storing clean rainwater in the middle and later periods and adjusting the flow of storm flood peaks.
Compared with the prior art, the invention has the beneficial effects that:
1. when the rainfall is large, the hollow curb stone can enable the rainwater in the middle and later periods to be discharged into the rainwater regulating pool 14 through the bottom water outlet 6, so that the water amount entering the green belt is reduced.
2. The rainwater well 13 is arranged in the green belt, rainwater in the green belt can be drained timely when accumulated water appears in the green belt, adverse effects on plant growth caused by long-time soaking of plants in water are avoided, meanwhile, the filter screen grid cover arranged at the top of the rainwater well can prevent garbage from entering, and the movable baffle plate arranged in the rainwater well cover can prevent odor from overflowing.
3. The rainwater regulating tank 14 can regulate the peak flow rate and store rainwater for recycling in sunny days. Because the initial rainwater is basically abandoned and seeps into the green belt, the rainwater collected in the rainwater adjusting tank at the middle and later periods is cleaner.

Detailed description of the invention
The invention is further illustrated by the following figures and examples:
the kerbstone shown in fig. 1 is a hollow structure, and the appearance of the hollow kerbstone can be made to be similar to that of a common kerbstone. The kerbstone is provided with a water inlet 1, a side water outlet 5 and a bottom water outlet 6, and the filter screens 2 are arranged at the water inlet 1 and the side water outlet 5, so that solid impurities can be prevented from entering the kerbstone. The floating ball 3 is connected through a connecting rope 4. Connect rope upper end to fix top in hollow water-permeable curb, the lower extreme is fixed on valve gap 7, and water level rises in hollow curb, and floater buoyancy increases, connects rope and can stimulate valve gap 7 and open, and rivers flow in the rainwater equalizing basin from bottom outlet 6.
The valve cover 7 has a certain dead weight, when the water level in the hollow curb stone is reduced, the buoyancy of the floating ball is reduced, and the valve cover falls down due to the dead weight to close the bottom water outlet.
The specific operation conditions of each part are as follows:
when the rainfall is small, the rainwater enters the hollow curb through the water inlet, and the rainwater is completely discharged into the green belt from the side water outlet 5.
Along with rainfall grow, because the inflow of water inlet is greater than the displacement of lateral part outlet, water level can constantly rise in the hollow curb, and floater 3 pulls valve gap 7 on bottom outlet 6 to open through connecting rope 4 under the buoyancy, and water is followed lateral part outlet 5, two outlet drains of bottom outlet 6.
Along with the rainfall reduction, the water level in the hollow kerbstone is reduced, the valve cover falls by the dead weight, the bottom water outlet 6 is closed, and the rainwater is drained from the side water outlet 5.
As shown in fig. 2, 3 and 4, the rainwater well 13 is positioned at the lower part of the green belt, and the rainwater grate 8 on the rainwater well 13 consists of a filter screen grating cover 9 and a well cover 12 below; the middle of the well cover is provided with a movable block 11, the movable block 11 is connected through a spring 10, and the spring is fixed on the filter screen grille 9; the movable block 11 in the middle of the well cover is made of light materials, and under the normal condition, the movable block keeps balance under the self gravity and the spring tension; when the rainfall is large and accumulated water with a certain thickness is formed at the upper part of the well cover, the movable block can descend under the gravity action of rainwater, and the rainwater flows away from the periphery of the movable block; when accumulated water flows out, the water is reset under the action of the spring 10; the open and close state of the rain grate is controlled by the rainfall, and the rain grate is in the close state at ordinary times, so that the odor can be prevented from overflowing.
As shown in fig. 4, the rainwater regulation pool 14 is buried underground and is connected with the drainage port 6 at the bottom of the hollow curb and the rainwater well 13 through pipelines; an overflow port 15 is formed in the upper portion of the rainwater regulating pool 14 and connected with a municipal drainage pipe network, and after the rainwater regulating pool 14 is filled with water, all residual water is drained through the municipal drainage pipe network; a submersible pump 17 is arranged in the rainwater regulating tank 14, and rainwater in the rainwater regulating tank can be used for sprinkling and greening in sunny days; meanwhile, the rainwater regulating tank 14 is provided with an access hole 16.
The above-mentioned embodiments, objects, technical solutions and advantages of the present invention are further described in detail, it should be understood that the above-mentioned embodiments are only illustrative of the present invention and are not intended to limit the present invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
