The body shadow of the grass planting bricks can be seen in daily life, the grass planting bricks are widely applied to parking lots, sidewalks and other scenes, and a plurality of grass planting bricks are combined together according to a certain shape to form a landscape. The novel air conditioner can not only facilitate people to go out, but also increase the greening area of a city, thereby improving the air.

A lot of present grass planting bricks are made of regular shapes, and most of the grass planting bricks have a water permeable function. When rainfall, the rainwater that falls into grass planting brick can realize grass planting brick's drainage function through in the soil of grass planting brick inflow below.

In hot summer, the grass planting bricks only have the function of water permeability and are not enough. In arid regions, after a large-scale rainfall, although some water is accumulated in the grass planting bricks in a short time, the water is easy to evaporate after the rainfall is finished, so that the residual water of the grass planting bricks is lost, namely, the water-fixing effect of the grass planting bricks is poor.

SUMMERY OF THE UTILITY MODEL

In order to reduce the water loss in the grass planting brick and improve the water fixing effect of the grass planting brick, the application provides an environment-friendly grass planting brick with a water storage function.

The application provides a pair of environment-friendly grass planting brick with retaining function adopts following technical scheme:

an environment-friendly grass planting brick with a water storage function comprises a brick body, a first water storage cavity, a second water storage cavity and a control component, the brick body is internally provided with a grass planting groove and a water suction hole, the first water storage cavity and the second water storage cavity are both arranged in the brick body, the second water storage cavity is arranged below the grass planting groove and is communicated with the grass planting bricks through the water suction holes, a limber hole is also arranged in the brick body, the lower end of the first water storage cavity is communicated with the second water storage cavity through the limber hole, the control component is arranged on the side wall of the second water storage cavity and comprises a baffle sheet which is rotatably connected inside the second water storage cavity and is used for sealing the water through hole when the water pressure of the first water storage cavity is the same as that of the second water storage cavity, the rotation axis of the separation blade is higher than the limber hole, and the top of the brick body is also provided with a water inlet hole for communicating the first water storage cavity with the outside.

Through adopting above-mentioned technical scheme, when the rainfall, through the action of gravity, partly rainwater in the rainfall passes through the inlet opening and gets into first water storage chamber, and along with the increase of the water yield in the first water storage intracavity, the water level in the first water storage intracavity constantly rises. Still some rainwater directly falls into the grass planting inslot, and some in these rainwater is absorbed by the soil in the grass planting inslot, is absorbed by the plant of planting in the grass planting inslot afterwards again, and another part rainwater permeates from soil, flows through the water-absorbing hole again, gets into second water storage chamber at last, and the water in the second water storage chamber constantly increases until the second water storage intracavity is full of the rainwater.

After the rainfall is finished, part of water in the grass planting groove is continuously absorbed by the plants. As the temperature of the natural air rises after rainfall, the other part of water absorbs heat and evaporates to become water vapor which flows into the air. Because the water in the first water storage cavity only contacts with the air through the water inlet hole, only a small part of the moisture in the first water storage cavity is evaporated, most of the moisture is still remained in the first water storage cavity, and the water level in the first water storage cavity is kept at a higher position. The water level in the grass planting inslot constantly reduces, and the water in the second water storage intracavity is constantly absorbed by the plant, the continuous grow of water level difference in first water storage chamber and second water storage chamber, because pressure increases along with the degree of depth increase of water, the degree of depth difference of first water storage chamber and second water storage intracavity water constantly increases, one side that the separation blade is close to first water storage chamber receives pressure great, the pressure that one side that the separation blade is close to second water storage chamber receives is less, because the pressure of separation blade both sides is different, the separation blade receives the pressure in first water storage chamber and removes to second water storage chamber direction, thereby the separation blade is opened, the water of first water storage intracavity storage constantly flows into second water storage chamber through the limbers, the water level difference in first water storage chamber and second water storage chamber constantly reduces. When the pressure difference between the first water storage cavity and the second water storage cavity is continuously reduced until the gravity of the separation blade cannot be overcome, the separation blade rotates downwards gradually and is slowly closed, and the water through hole is closed.

The plant constantly absorbs the moisture in the second water storage chamber, and the moisture in second water storage chamber constantly reduces, and the difference in water level in first water storage chamber and second water storage chamber constantly grow again, and the separation blade is opened, and the rivers in first water storage chamber are to second water storage intracavity, until the separation blade is closed. The process is repeated continuously until the pressure difference between the first water storage cavity and the second water storage cavity is not enough to push the blocking piece to move.

Optionally, the control assembly further comprises a telescopic rod, one end of the telescopic rod is hinged to the side wall of the second water storage cavity, and the other end of the telescopic rod is hinged to the blocking piece.

Through adopting above-mentioned technical scheme, because the weight of separation blade is lighter, when the water level difference in first water storage chamber and second water storage chamber is less, the pressure differential of separation blade both sides alright promote the separation blade when very little, the process of opening and shutting of separation blade is too frequent. The water level in the second water storage cavity and the water level in the first water storage cavity are always kept at a smaller difference, the moisture in the second water storage cavity is far larger than the moisture required by plants, and the redundant moisture can be lost through soil evaporation. Through the telescopic link of connecting on the separation blade, still need promote the telescopic link when the separation blade removes, consequently can increase and promote the required pressure threshold value of separation blade removal. When the difference between the water levels of the first water storage cavity and the second water storage cavity is large, the blocking piece can be opened, the loss of water can be reduced, and the utilization rate of water in the grass planting brick is improved.

Optionally, the control assembly further comprises a spring disposed in the telescopic rod and used for resetting the telescopic rod.

By adopting the technical scheme, the pressure threshold value of the separation blade during movement can be further increased through the spring, and the elastic force of the spring needs to be overcome when the separation blade is opened. When the baffle plate is opened, the spring is stretched. When the separation blade began to close, can resume the normal position fast with the separation blade through the pulling force of spring to the telescopic link, avoid too much water to get into second water storage chamber.

Optionally, a waterproof gasket used for being attached to the side wall of the second water storage cavity is installed on one side, close to the limber hole, of the blocking piece.

Through adopting above-mentioned technical scheme, waterproof gasket can closely laminate with second water storage chamber lateral wall, can prevent that the lateral wall laminating in separation blade and second water storage chamber from not strictly leading to moisture to flow into second water storage chamber from first water storage intracavity, has promoted the sealed effect in first water storage chamber and second water storage chamber, and then has improved the water storage effect in first water storage chamber.

Optionally, the environment-friendly grass planting brick with the water storage function further comprises a water absorption structure arranged in the brick body, wherein the water absorption structure comprises a first water absorption plate arranged below the water absorption holes.

Through adopting above-mentioned technical scheme, when the rainfall, the moisture that oozes in the soil can be fully absorbed by first water absorption plate, and then flows into second water storage chamber with absorbent moisture, increases the water storage efficiency in second water storage chamber. Simultaneously, first water absorption plate can also prevent that soil from getting into the second water storage intracavity and leading to the second water storage intracavity soil to pile up and block up the separation blade.

Detailed Description

The present application is described in further detail below with reference to figures 1-4.

The embodiment of the application discloses an environment-friendly grass planting brick with a water storage function. Referring to fig. 1, the environment-friendly grass planting brick with the water storage function comprises a brick body 1, a first water storage cavity 2, a second water storage cavity 3, a control component 4 and a water absorption structure 5.

The brick body 1 is internally provided with a grass planting groove 11, a water inlet hole 12 and a water suction hole 13. First water storage chamber 2, second water storage chamber 3 all set up in the brick body 1, and second water storage chamber 3 sets up in the below of grass planting groove 11 and through the hole 13 and the 11 intercommunications of grass planting groove that absorb water. The first water storage cavity 2 is communicated with the outside through a water inlet hole 12.

In this embodiment, the grass planting trough 11 is located in the middle of the brick body 1 and is cylindrical for placing soil for planting plants. It should be noted that, the depth and the aperture of the grass planting groove 11 are not specifically limited in the present application, and the depth and the aperture of the grass planting groove 11 can be adjusted according to actual conditions. The water inlet holes 12 and the water suction holes 13 in the embodiment are provided in a plurality, and the specific number can be adjusted according to different scenes.

When the rainfall, partly rainwater passes through inlet opening 12 and gets into first water storage chamber 2 in, another part rainwater directly falls into grass planting groove 11, and wherein, the partly infiltration function that can be absorbed by soil, another part passes through soil in the rainwater that falls into grass planting groove 11 flows into second water storage chamber 3 from water absorption hole 13 in to make the water in second water storage chamber 3 constantly increase.

Referring to fig. 1, 2 and 3, in a specific embodiment, a water through hole 14 is further formed in the brick body 1, and the lower end of the first water storage cavity 2 is communicated with the second water storage cavity 3 through the water through hole 14; wherein, control assembly 4 sets up on the lateral wall of second water storage chamber 3, and control assembly 4 is including rotating the separation blade 41 who connects in the inside second water storage chamber 3, and separation blade 41 is used for airtight with limbers 14 when first water storage chamber 2 is the same with second water storage chamber 3 water pressure, and wherein, the axis of rotation of separation blade 41 is higher than limbers 14.

In this embodiment, the blocking plate 41 is rotatably connected to the inner side of the second water storage cavity 3 through a rotating shaft.

After the weather turns fine, as the temperature gradually rises, part of water in the grass planting groove 11 and the second water storage cavity 3 absorbs heat and evaporates, and the other part of water is absorbed by plants, so that the water levels in the grass planting groove 11 and the second water storage cavity 3 are continuously reduced; at this time, since the water in the first water storage chamber 2 is in contact with the air only through the water inlet hole 12 and most of the moisture remains in the first water storage chamber 2, the water level in the first water storage chamber 2 is substantially maintained. In other words, the water level difference between the first water storage cavity 2 and the second water storage cavity 3 is continuously increased, and based on the principle that the pressure is continuously increased along with the increase of the depth of water, the water level difference between the water in the first water storage cavity 2 and the water in the second water storage cavity 3 is continuously increased, so that the side of the blocking piece 41 close to the first water storage cavity 2 is subjected to larger pressure, and the side of the blocking piece 41 close to the second water storage cavity 3 is subjected to smaller pressure; in other words, the pressure applied to the two sides of the blocking plate 41 is different, specifically: the pressure of separation blade 41 towards first water storage chamber 2 one side is greater than the pressure towards second water storage chamber 3 one side, the water in first water storage chamber 2 promotes separation blade 41 and takes place relative rotation with second water storage chamber 3 lateral wall, thereby make limbers 14 open, and make the water in first water storage chamber 2 constantly supply to second water storage chamber 3 in through limbers 14, that is to say, at this in-process, the water head of first water storage chamber 2 and second water storage chamber 3 constantly reduces, lead to the water level in first water storage chamber 2 can descend and the water level in second water storage chamber 3 can rise, make the pressure differential of first water storage chamber 2 and second water storage chamber 3 constantly reduce, lead to the unable liftoff 41 of water in first water storage chamber 2, that is to say, 41 rotates downwards gradually until airtight limbers 14.

As is well known, the plant can constantly absorb the moisture in the second water storage chamber 3, so that the moisture in the second water storage chamber 3 can constantly be reduced, and further the water level difference between the first water storage chamber 2 and the second water storage chamber 3 is constantly enlarged, so that the baffle plate 41 is reopened, and then the water in the first water storage chamber 2 continues to flow into the second water storage chamber 3. In other words, the stopper 41 repeats the opening and closing of the water passage hole 14 with a change in the water head difference.

In a specific embodiment, the control assembly 4 further includes an expansion link 42, specifically, the expansion link 42 includes a fixed cylinder 421 and a moving portion 422, wherein a end of the moving portion 422 is sleeved on the fixed cylinder 421, so that the moving portion 422 can slide back and forth along the length direction of the fixed cylinder 421, one end of the fixed cylinder 421, which is far away from the blocking piece 41, is hinged on the side wall of the second water storage cavity 3, and the other end of the moving portion 422 is rotatably connected with the blocking piece 41 through hinging.

Specifically, the blocking piece 41 of the present embodiment is made of a light material, such as plastic, so that the blocking piece 41 has a light weight, and when the difference between the water levels of the first water storage cavity 2 and the second water storage cavity 3 is small, the blocking piece 41 is relatively easy to open and close the water through hole 14, in other words, the opening and closing processes of the blocking piece 41 are too frequent, so that the water in the first water storage cavity 2 is continuously supplemented into the second water storage cavity 3. Because the water in the second water storage cavity 3 not only can be absorbed by the plant, but also the moisture in the second water storage cavity 3 can run off due to evaporation, so that the water retained in the second water storage cavity 3 can be continuously reduced, and it is worth noting that the moisture running off due to evaporation is far more than the moisture absorbed by the plant, most of the water in the second water storage cavity 3 can not be absorbed by the plant and evaporated, so the utilization rate of the moisture in the second water storage cavity 3 can be lower.

The telescopic link 42 in this embodiment makes the water in the first water storage cavity 2 not only overcome the gravity of the separation blade 41 when pushing the separation blade 41 to rotate, but also overcome the acting force of the telescopic link 42 on the separation blade 41, in other words, the telescopic link 42 can increase the pressure threshold value required for pushing the separation blade 41 to rotate, and then the separation blade 41 can be controlled to open and close when the first water storage cavity 2 and the second water storage cavity 3 reach the preset water pressure difference, thereby reducing the amount of water flowing into the second water storage cavity 3 from the first water storage cavity 2 in the opening and closing process of the separation blade 41 at every time, and reducing the water loss in the second water storage cavity 3 due to evaporation greatly, thereby reducing the unnecessary water loss.

In a particular embodiment, the control assembly 4 further comprises a spring 43 for resetting the telescopic rod 42. One end of the spring 43 is fixed to the bottom of the fixed cylinder 421, and the other end is fixed to the end of the moving part 422 away from the stopper 41.

In this embodiment, the pushing force required by the water in the first water storage chamber 2 to push the blocking piece 41 to rotate can be further increased by the spring 43, that is, the elastic force of the spring 43 needs to be overcome when the blocking piece 41 is opened. When the pressure difference between the first water storage cavity 2 and the second water storage cavity 3 reaches the preset pressure threshold, the water in the first water storage cavity 2 pushes the blocking piece 41 to rotate, and the blocking piece 41 drives the moving part 422 to move, so that the spring 43 starts to stretch. The water in the first water storage cavity 2 is continuously supplemented to the second water storage cavity 3 until the pressure difference between the first water storage cavity 2 and the second water storage cavity 3 is smaller than the elastic force of the spring 43, the acting force of the telescopic rod 42 and the gravity of the blocking piece 41, and at the moment, the blocking piece 41 is close to the limber hole 14 and closes the limber hole under the pulling force reset action of the spring 43. When the blocking piece 41 is closed, the spring 43 pulls the telescopic rod 42 against the blocking piece 41, so that the blocking piece 41 is kept tightly attached to the side wall of the second water storage cavity 3 when the blocking piece 41 is restored, and the water in the first water storage cavity 2 is prevented from flowing into the second water storage cavity 3 due to the fact that the blocking piece 41 is not tightly attached.

In a specific embodiment, a waterproof gasket 44 for adhering to the side wall of the second water storage cavity 3 is installed on one side of the blocking piece 41 close to the water through hole 14.

In this embodiment, the waterproof gasket 44 may be connected to the blocking plate 41 by bonding, and the waterproof gasket 44 is made of an elastic material such as silicone. Waterproof gasket 44 can closely laminate with the lateral wall in second water storage chamber 3, and then prevents that the lateral wall laminating in separation blade 41 and second water storage chamber 3 from not strictly leading to moisture to flow into second water storage chamber 3 from first water storage chamber 2, has promoted the sealed effect in first water storage chamber 2 and second water storage chamber 3, and then has improved the water storage effect in first water storage chamber 2.

In one embodiment, the absorbent structure 5 comprises a first absorbent sheet 51 and a first absorbent rod 52 disposed below the water-absorbing openings 13.

In this embodiment, the first water absorption plate 51 can only pass through water molecules, the first water absorption plate 51 is transversely disposed below the water absorption holes 13, the first water absorption rod 52 is vertically disposed at the lower side of the first water absorption plate 51, and meanwhile, one end of the first water absorption rod 52 is disposed in the first water absorption plate 51, and the other end of the first water absorption rod abuts against the bottom of the second water storage cavity 3.

In the case of rainfall, the water seeped from the soil flowing through the water suction holes 13 is sufficiently absorbed by the first water suction plate 51 and then flows into the second water storage chamber 3, in other words, the first water suction plate 51 can increase the water storage efficiency of the second water storage chamber 3. Meanwhile, the first water absorbing plate 51 can also reduce the blocking piece 41 blocked by the soil accumulated in the second water storage cavity 3 caused by the soil entering the second water storage cavity 3, thereby ensuring the normal operation of the blocking piece 41.

It should be understood that, when the water level in the second water storage chamber 3 is low, since the first water absorbing plate 51 is not in direct contact with the water in the second water storage chamber 3, the first water absorbing plate 51 can only absorb the water in the second water storage chamber 3 by the evaporation of the water, and therefore, the efficiency of the first water absorbing plate 51 absorbing the water from the second water storage chamber 3 is low. The lower extreme of first water absorption rod 52 in this embodiment and the lower water contact of water level in the second water storage chamber 3 for water in the second water storage chamber 3 is absorbed to first water absorption plate 51 more easily in, and then is favorable to the plant to absorb the water in first water absorption plate 51, thereby has promoted the water absorption efficiency of first water absorption plate 51.

In a specific embodiment, the water absorbing structure 5 further comprises a second water absorbing plate 53 and a second water absorbing rod 54.

In this embodiment, the second water suction plate 53 is horizontally disposed at the top of the first water storage cavity 2, one end of the second water suction rod 54 is disposed at the bottom of the first water storage cavity 2, and the other end is disposed in the second water storage cavity 3.

The second board 53 that absorbs water is similar with first board 51 that absorbs water structure, because the second board 53 that absorbs water can only pass through the hydrone, and then can reduce the evaporation of water that sunshine arouses in penetrating into first water storage chamber 2, consequently reduced the moisture loss in the first water storage chamber 2 to the water storage effect in first water storage chamber 2 has been improved.

When the water level in first water storage chamber 2 is lower, be difficult to open separation blade 41 through the pressure differential, can reserve partly moisture in first water storage chamber 2, this part of water is difficult to get into in second water storage chamber 3, can only run off through the evaporation, this waste that can cause the water resource, so this application absorbs the moisture that stick 54 can be with reserving in first water storage chamber 2 through the second and absorbs to second water storage chamber 3, and then absorbed by first water absorption stick 52, the waste of moisture in first water storage chamber 2 has been reduced, consequently, the moisture utilization ratio in first water storage chamber 2 has been improved.

Referring to fig. 4, when it rains too much, rainwater stays at the upper portion of the brick body 1, and if the rainwater cannot be drained in time, much rainwater is accumulated around the brick body 1, which may hinder normal passage of vehicles and pedestrians. Consequently, drainage channel 15 has been seted up to four sides of the brick body 1 of this embodiment, and is specific, the setting of adjacent drainage channel 15 intercommunication to in the laying process of grass planting brick, drainage channel 6 can be formed to the drainage channel 15 of the adjacent brick body 1, can continue the drainage and drain away the accumulational moisture in brick body 1 top through drainage channel 6.

The implementation principle of the environment-friendly grass planting brick with the water storage function in the embodiment of the application is as follows: when there is the rainfall, partly rainwater is earlier through inlet opening 12 and the second suction plate 53 that flows through, then flows into in the first water storage chamber 2, and first water storage chamber 2 begins to impound this moment, and another part rainwater directly falls into grass planting groove 11 in, and wherein partly soil absorption by grass planting groove 11 is gone into, and another part enters into first suction plate 51 and flows into second water storage chamber 3 through the infiltration of soil and the direction of suction opening 13, and second water storage chamber 3 begins to impound this moment.

After the weather turns fine, part of water in the grass planting groove 11 and the second water storage cavity 3 absorbs heat and evaporates, and the other part of water is absorbed by plants, so that the water level in the grass planting groove 11 and the second water storage cavity 3 is continuously reduced. At this time, the water level in the first water storage chamber 2 is maintained substantially constant. The difference between the water levels of the first water storage cavity 2 and the second water storage cavity 3 is increased, and the water in the first water storage cavity 2 pushes the blocking piece 41 to rotate through the rotating shaft due to the difference of the pressures on the two sides of the blocking piece 41, so that the limber hole 14 is opened. The water in the first water storage cavity 2 is continuously supplemented to the second water storage cavity 3 through the limbers 14, the difference between the water levels of the first water storage cavity 2 and the second water storage cavity 3 is continuously reduced, so that the pressure difference between the first water storage cavity 2 and the second water storage cavity 3 is continuously reduced, until the pressure difference between the first water storage cavity 2 and the second water storage cavity 3 cannot overcome the gravity of the separation blade 41, the acting force of the telescopic rod 42 and the elastic force of the spring 43, the separation blade 41 rotates downwards to be closed, and the first water storage cavity 2 stops supplementing water to the second water storage cavity 3.

The plant constantly absorbs the moisture in second water storage chamber 3, and the moisture in second water storage chamber 3 constantly reduces, and the water level difference of first water storage chamber 2 and second water storage chamber 3 constantly grow again, and separation blade 41 opens, and the rivers in first water storage chamber 2 are to second water storage chamber 3 in, until separation blade 41 is closed. Through the process, the water in the grass planting bricks is fully utilized, the loss of the water in the grass planting bricks is reduced, and the water storage effect of the grass planting bricks is improved.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: equivalent changes in structure, shape and principle of the present application shall be covered by the protection scope of the present application.
