Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
The first embodiment is as follows:
referring to fig. 1-4, a road greening median is used in sponge city, includes two curb 1 that set up along road central symmetry, and stock solution chamber 2 has been seted up to the lateral wall of curb 1, and the drawing liquid chamber 3 with stock solution chamber 2 intercommunication is seted up to the lateral wall of curb 1, and first check valve 31 is installed with the intercommunication department in drawing liquid chamber 3 in stock solution chamber 2, and the sealed sliding connection has sliding plug 4 that magnetic material made in the drawing liquid chamber 3, installs second check valve 41 on the sliding plug 4.
It should be noted that the first check valve 31 allows water to flow only from the reservoir chamber 2 to the pumping chamber 3, and the second check valve 41 allows water to flow only from the right side of the spool 4 to the left side of the spool 4.
The side wall of the sliding plug 4 is elastically connected to the inner wall of the liquid pumping cavity 3 through a spring 5, a three-way pipe 6 is embedded at the upper end of the curb 1, and the lower end of the three-way pipe 6 is communicated with the interior of the liquid storage cavity 2.
The upper end of the three-way pipe 6 is provided with a water inlet 61, the side wall of the three-way pipe 6 is provided with a plurality of capillary holes 62, the three-way pipe 6 is rotatably connected with a straight pipe 7, the upper end and the lower end of the straight pipe 7 are both provided with through holes 71, and the water outlet end of the straight pipe 7 is fixedly connected with the inner wall of the three-way pipe 6 through a memory metal strip 8.
It should be noted that the inner wall of the straight pipe 7 is closely attached to the outer wall of the three-way pipe 6, one end of the straight pipe 7 is rotatably connected to the inner wall of the three-way pipe 6, the other end of the straight pipe 7 is fixedly connected to the memory metal strip 8, and one end of the memory metal strip 8, which is far away from the straight pipe 7, is fixedly connected to the inner wall of the three-way pipe 6.
Furthermore, the memory metal strip 8 is made of alloy material with two-way memory effect, such as Cu-Zn-Sn alloy, and is in a twist shape when the temperature is higher and exceeds the metamorphosis temperature, and is restored to a sheet shape and is in a straightening state under the condition of lower temperature, so that the straight pipe 7 fixedly connected with the memory metal strip can be driven to rotate back and forth. Through reasonable design of the length of the memory metal strip 8 and the fixed position of the straight tube 7, the rotation angle of the straight tube 7 can reach 90 degrees.
One end of the straight pipe 7 is communicated with the liquid pumping cavity 3 through a first guide pipe 9, and the other end of the straight pipe 7 is communicated with the interior of the liquid storage cavity 2 through a second guide pipe 10.
The invention also provides a construction method of the greening isolation belt for the sponge city, which comprises the following steps:
s1, presetting an isolation belt, cleaning an area with the width of about 2m in the middle of a road, and excavating a base groove in the isolation belt area;
s2, constructing the road surface, building kerbs 1 on two sides of the isolation belt area, and digging anti-seepage grooves between the kerbs 1 and the road surface;
s3, pre-burying a maintenance pipe, burying the maintenance pipe in the anti-seepage groove, and forming seepage holes in the maintenance pipe;
s4, filling soil, namely filling earthwork 11 between the two side kerbs 1, and covering the maintenance pipes, wherein the soil height is required to be lower than the height of the kerbs 1;
and S5, planting greening plants, and planting related greening plants on the filled earthwork 11.
In the use process of the device in the embodiment, in rainy season, the temperature is low and can not reach the metamorphosis temperature of the memory metal strip 8, the memory metal strip 8 is in a straight state, so that the through hole 71 at the upper end of the straight pipe 7 is opposite to the water inlet 61, the through hole 71 at the lower end of the straight pipe 7 is communicated with the lower pipe part of the three-way pipe 6 (as shown in fig. 2), and rainwater can flow into the liquid storage cavity 2 from the water inlet 61 for storage.
When the weather is clear, the memory metal strip 8 reaches the metamorphosis temperature and recovers the twisted shape (as shown in fig. 3), at the moment, the straight pipe 7 fixedly connected with the memory metal strip is driven to rotate 90 degrees (as shown in fig. 4), and the through holes 71 of the straight pipe 7 are opposite to the capillary holes 62 on the two sides of the three-way pipe 6. On one hand, rainwater evaporation loss from the water inlet 61 caused by sunlight irradiation can be avoided; on the other hand, because most of the automobiles are made of iron-containing materials, when vehicles continuously run on two sides of the green belt, the magnetic sliding plug 4 can be attracted to move in the same direction with the vehicles, after the automobiles leave, the spring 5 pushes the sliding plug 4 to reset, so that the sliding plug 4 can move back and forth in the liquid pumping cavity 3, and under the flow limiting effect of the first check valve 31 and the second check valve 41, rainwater in the liquid storage cavity 2 can be continuously pumped into the straight pipe 7 and then flows back to the liquid storage cavity 2 through the second guide pipe 10.
In the flowing process of rainwater in the straight pipe 7, because the aperture of the capillary holes 62 is extremely small, under the action of the surface tension of water, the water in the straight pipe 7 cannot flow out through the capillary holes 62, meanwhile, the water in the straight pipe 7 has high speed and low pressure, and the air outside the straight pipe 7 flows slowly and has high pressure, so that pressure difference is generated inside and outside the straight pipe 7, and dust-containing air outside the straight pipe 7 can be sucked into the straight pipe 7 through the capillary holes 62 to be mixed with the water in the straight pipe to achieve the purpose of dust removal.
And it is worth mentioning that, in the driving process of the passing vehicles, the raised dust cannot rise too high under the action of gravity, and most of the raised dust is located at a lower position away from the road surface, so that the device can absorb and treat most of the raised dust, and the dust content in the air is greatly reduced.
Example two:
referring to fig. 5, different from the first embodiment, a spiral coil 12 is embedded on the inner wall of the liquid pumping chamber 3, a color lamp 63 coupled with the spiral coil 12 is installed at the upper end of the three-way pipe 6, and the memory metal strip 8 is coupled in a closed circuit formed by the spiral coil 12 and the color lamp 63 through a photoresistor 81.
It should be noted that the connection method and the installation method among the spiral coil 12, the color lamp 63, the memory metal strip 8 and the photo resistor 81 are all mature technical means in the prior art, and are not related to the design purpose of the present solution, and therefore are not described herein again. In the embodiment, the three-way pipe 6 near the light-sensitive resistor 81 is made of a transparent material, so that the light-sensitive resistor 81 can receive light.
The sliding plug 4 will enter and exit the spiral coil 12 continuously in the process of moving back and forth in the liquid pumping cavity 3, and the magnetic flux in the spiral coil 12 is changed continuously, so that the induced current is generated to make the colored lamp 63 coupled with the spiral coil 12 flash and emit light, and the landscape effect of the road greening isolation belt is improved.
In addition, more importantly, the induced current generated by the spiral coil 12 passes through the photosensitive resistor 81 and the memory metal strip 8, in a sunny season, after the photosensitive resistor 81 is illuminated, the resistance value of the photosensitive resistor becomes small, the current can be supplied to the colored lamp 63 through the memory metal strip 8, when the current passes through the memory metal strip 8, the memory metal strip 8 heats up due to the heat effect of the current, so that the metamorphosis temperature of the memory metal strip 8 is reached, finally, the memory metal strip 8 is twisted into a twist shape and drives the straight pipe 7 to rotate for 90 degrees, and the dust adsorption work in the first embodiment can be carried out. By the design, the device can work normally in winter with lower temperature.
In rainy season, the resistance value of the photosensitive resistor 81 is increased under the condition of no illumination, so that a closed circuit is disconnected, no current passes through the memory metal strip 8, and on one hand, the phenomenon that each part is damaged due to short circuit in rainy season can be prevented; on the other hand, the memory metal strip 8 is in a straight state without heating and temperature rise, and drives the straight pipe 7 to rotate, so that the rainwater collection operation in the first embodiment can be performed.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
