Description

Technical Field

[0001] The present application relates to the field of road construction, and in particular to a drainage structure for municipal greening projects. Background Art

[0002] Municipal engineering generally belongs to the country's infrastructure, which refers to the construction of various public transportation facilities, water supply, exhaust, gas, urban flood control, environmental sanitation and lighting infrastructure in urban construction. It is an indispensable material basis for the survival and development of cities.

[0003] With the development of cities, parks are usually built in cities. On the one hand, they increase the green area of ​​the city, on the other hand, they alleviate the urban heat island effect. At the same time, they can accumulate rainwater on rainy days to alleviate urban waterlogging, among which road drainage is one of the key points.

[0004] In the related art, permeable bricks are usually used when paving the road surface of the park. The permeable properties of the permeable bricks are utilized to collect rainwater on rainy days, making it difficult for water to accumulate on the road surface.

[0005] With respect to the above-mentioned related technologies, the inventors found that the water permeability of the permeable bricks remains unchanged. When the rainfall is heavy, rainwater tends to accumulate on the road surface, causing the water permeability of the road surface to decrease, so there is room for improvement. Summary of the invention

[0006] In order to improve the water permeability of the road surface, the present application provides a drainage structure for municipal greening projects.

[0007] The present application provides a drainage structure for municipal greening projects, which adopts the following technical solutions:

[0008] A drainage structure for a municipal greening project comprises a road body and curbs, wherein the curbs are arranged on both sides of the road body, a water collecting trough is provided on a side of the curb close to the road body, and a siphon assembly is provided in the water collecting trough;

[0009] The siphon assembly includes a partition plate, a pressure plate and a siphon tube, the partition plate is arranged in the water collecting trough and pressed against the inner wall of the water collecting trough, the pressure plate is pressed against the inner wall of the water collecting trough, the pressure plate is arranged on the side of the partition plate close to the curb, a siphon space is formed between the pressure plate and the partition plate, a water inlet hole connected to the siphon space is provided on the pressure plate, the siphon tube is slidably connected to the partition plate in a vertical direction, the siphon tube is arranged in the siphon space, a control chamber connected to the water collecting trough is provided in the road body in a vertical direction, a control assembly for controlling the lifting of the siphon tube is provided in the control chamber, the control assembly extends into the water collecting trough and is connected to an end of the siphon tube away from the pressure plate, and a water inlet trough connected to the control chamber is provided on the inner wall of the water collecting trough.

[0010] By adopting the above technical scheme, on rainy days, rainwater flows from the road body into the ditch of the curb, falls on the partition plate, and then enters the siphon space from the water inlet hole. When the height of the liquid level of rainwater between the partition plate and the pressure plate is higher than the siphon tube, the pressure between the pressure plate and the partition plate is greater than the pressure in the siphon space. At this time, the rainwater continues to fall through the siphon tube, making it difficult for rainwater to accumulate on the partition plate and overflow the ditch. In the process of collecting rainwater in the siphon space, part of the rainwater enters the control cavity through the water inlet trough, the rainwater contacts the control component and drives the control component to move. The movement of the control component drives the siphon tube. The end of the siphon tube close to the pressure plate moves toward the partition plate, which reduces the reaction speed of the siphon effect, speeds up the speed at which the siphon tube sucks rainwater into the ditch, and further reduces the possibility of rainwater overflowing from the ditch, thereby improving the water permeability of the road surface.

[0011] Preferably, the control assembly includes a control plate, a connecting plate, a first connecting rod and a second connecting rod, the control plate is slidably connected in the control cavity, a connecting groove is provided on the inner wall of the control cavity, the connecting plate is slidably connected in the connecting groove, the connecting plate is arranged on the side of the control plate away from the road body, the inner wall of the water collecting tank is provided with a connecting cavity connected to the connecting groove, the first connecting rod is slidably connected in the connecting cavity, the first connecting rod is arranged on the side of the connecting plate away from the control plate, the second connecting rod is arranged on the side of the first connecting rod away from the connecting plate, one end of the second connecting rod away from the first connecting rod is connected to one end of the siphon away from the pressure plate, and the second connecting rod is parallel to the connecting plate.

[0012] By adopting the above technical solution, on rainy days, rainwater enters the ditch of the curb from the road body and falls between the partition plate and the pressure plate, wherein part of the rainwater enters the control cavity from the water inlet trough, and part of the rainwater contacts the control plate and exerts pressure on the control plate. When the weight of the rainwater entering the control cavity reaches a certain value, the rainwater drives the control plate to move in a direction away from the road body. During the downward movement of the control plate, the control plate contacts the connecting plate and drives the connecting plate to move in a direction away from the road body. The connecting plate then drives the first connecting rod and the second connecting rod to move in a direction away from the road body. The second connecting rod then drives the siphon tube to move in a direction away from the road body, so that the end of the siphon tube close to the pressure plate moves toward the direction close to the partition plate, thereby accelerating the speed of the siphon effect in the siphon space, further reducing the possibility of rainwater overflowing the ditch, and thus improving the water permeability of the road surface.

[0013] Preferably, a regulating cavity is provided in the road body, a regulating assembly is provided in the regulating cavity, a power piece is provided in the water collecting tank, the power piece is arranged on a side of the partition plate away from the pressure plate, and the power piece extends into the regulating cavity and is connected to the regulating assembly;

[0014] The adjustment component includes a follower and a fan blade, the follower is arranged in an adjustment cavity, the fan blade is connected to the follower, and one end of the follower away from the fan blade is connected to the power member. The inner wall of the adjustment cavity is provided with an adjustment hole connected to the control cavity, the fan blade and the adjustment hole are arranged opposite to each other, and a reset component for controlling the reset of the control board and the connecting board is provided in the control cavity.

[0015] By adopting the above technical solution, when the rainfall gradually decreases and a siphon effect is generated in the siphon space, rainwater falls from the siphon tube and contacts the power part, the power part starts and drives the follower to start, the follower starts and drives the fan blades to rotate, the fan blades rotate and blow air toward the adjustment cavity, the wind enters the control cavity from the adjustment hole, and when the wind passes through the control plate and the rainwater stored in the control cavity, the wind drives the rainwater to re-enter the water collection tank from the water inlet trough, at this time, the pressure of the rainwater on the control plate is reduced, the reset component starts and drives the control plate to move in the direction close to the road body and reduces the pressure on the connecting plate, and at the same time, the reset component drives the connecting plate to move in the direction close to the road body, the connecting plate then drives the first connecting rod and the second connecting rod to move in the direction close to the road body, the second connecting rod then drives the siphon tube to move in the direction close to the road body, so that the speed of the siphon effect in the siphon space is gradually slowed down;

[0016] When the rainfall is heavy, the amount of rainwater absorbed by the siphon tube decreases, reducing the power of the power parts, thereby reducing the rotation speed of the fan blades, and reducing the total amount of rainwater blown between the control panel and the control chamber into the sump by the fan blades. The speed of the siphon effect in the siphon space is kept within a certain range, reducing the possibility of rainwater overflowing the sump, and realizing dynamic adjustment of the speed of the siphon effect in the siphon space, reducing the steps of manual intervention, thereby improving the permeability of the road body.

[0017] Preferably, the reset assembly includes a first reset spring and a second reset spring, the first reset spring is arranged in the adjusting cavity, one end of the first reset spring is connected to the side of the control plate close to the road body, and the other end is connected to the inner wall of the control cavity; the second reset spring is arranged in the connecting groove, the second reset spring is sleeved on the first connecting rod, one end of the second reset spring is connected to the side of the connecting plate away from the road body, and the other end is connected to the inner wall of the connecting groove.

[0018] By adopting the above technical solution, when the rainfall is heavy, part of the rainwater enters the control cavity and exerts pressure on the control plate. At this time, the first return spring is in a stretched state. When the total amount of rainwater reaches a certain value, the rainwater drives the control plate to move toward the connecting plate and exerts pressure on the connecting plate. The connecting plate moves in a direction away from the road body. At this time, the second return spring is in a compressed state. When the fan blades rotate, the fan blades blow air into the control cavity and drive the rainwater between the control cavity and the control plate into the sump. At this time, the total amount of rainwater in the control cavity is reduced and the pressure on the control plate is reduced. Under the action of the rebound force of the first return spring, the control plate moves toward the road body. The control plate is separated from the connecting plate, and under the action of the rebound force of the second reset spring, the connecting plate moves toward the direction close to the road body, and the connecting plate drives the first connecting rod and the second connecting rod to move toward the direction close to the road body, and the second connecting rod drives the siphon tube to move toward the direction close to the road body. Under the action of the first reset spring and the second reset spring, the control plate and the connecting plate are easily reset, and at the same time, it provides convenience for dynamically adjusting the speed of the siphon effect in the siphon space, and facilitates the siphon tube in the siphon space to control the speed of the siphon effect according to the amount of rainfall, thereby improving the water permeability of the road body.

[0019] Preferably, a protective sleeve is sleeved on the first return spring, one end of the protective sleeve is connected to one end of the control board close to the road body, and the other end of the protective sleeve is connected to the inner wall of the control cavity.

[0020] By adopting the above technical solution, when rainwater enters the control cavity, the protective cover provides protection for the first return spring, reducing the possibility of rusting of the first return spring, and facilitating the first return spring to reset the control board.

[0022] By adopting the above technical solution, when the rainfall is heavy, the siphon moves in the direction away from the road body, and when the limit plate and the limit groove collide, the fastest speed of the siphon effect in the siphon space is reached, which speeds up the extraction speed of the siphon for rainwater and improves the water permeability of the road body. In addition, the distance between the limit plate and the end of the siphon close to the pressure plate is greater than the vertical height of the water inlet hole, so that when the limit plate and the limit groove collide, the siphon effect can still be generated in the siphon space.

[0023] Preferably, a partition net is provided in the water collecting trough, and the partition net is arranged on a side of the power member away from the partition plate, and a storage space for storing rainwater is formed between the partition net and the bottom of the water collecting trough.

[0024] By adopting the above technical solution, after the siphon tube sucks rainwater into the sump, the partition net filters the rainwater when it passes through the partition net, making it difficult for impurities carried in the rainwater to enter the storage space, thereby reducing the possibility of impurities staying in the rainwater for a long time and causing the rainwater in the storage space to produce odor.

[0025] Preferably, a cleaning assembly is provided between the partition net and the power member;

[0026] The cleaning assembly includes an auger and a driving member. The auger is rotatable along the length direction of the curb and is connected to the water collecting trough.

[0027] By adopting the above technical solution, after the rain stops, the operator can start the driving part, which drives the auger to rotate. The auger rotates and contacts the impurities separated by the partition net. Under the action of the auger, the impurities on the partition net move toward the collection box, which is convenient for the subsequent collection of the impurities and reduces the possibility of excessive impurities blocking the partition net.

[0031] By adopting the above technical solution, after the operator controls the auger to transport the impurities on the partition net to the collection box, the operator rotates the cover plate in the direction away from the curb. The rotation of the cover plate drives the first connecting ring to rotate. The first connecting ring drives one end of the elastic rope to move toward the bottom of the groove away from the collection groove. The other end of the elastic rope drives the second connecting ring to move toward the bottom of the groove away from the collection groove. At this time, the operator can take the collection box out of the collection groove, so that the operator can take out the impurities in the collection box.

DETAILED DESCRIPTION

[0041] The following is combined with Figure 1-4 This application is described in further detail.

[0042] The present application embodiment discloses a drainage structure for municipal greening projects. Figure 1 and Figure 2 A drainage structure for municipal greening engineering includes a road body 1 and a curb 2. The curb 2 is arranged on both sides of the road body 1. A water collecting trough 21 is provided on the side of the curb 2 close to the road body 1. A siphon assembly 3 is provided in the water collecting trough 21. The siphon assembly 3 includes a partition plate 31, a pressure plate 32 and a siphon pipe 33. The partition plate 31 is fixed to the inner wall of the water collecting trough 21. The pressure plate 32 is fixed to the inner wall of the water collecting trough 21 and is arranged on the side of the partition plate 31 close to the road body 1. The siphon pipe 33 reciprocates along the vertical direction between the partition plate 31 and the pressure plate 32. On the breaking plate 31, a siphon space 34 is formed between the pressure plate 32 and the partition plate 31, the siphon tube 33 is arranged in the siphon space 34, a water inlet hole 321 connected to the siphon space 34 is opened on the partition plate 31, a control cavity 11 connected to the water collecting tank 21 is opened in the road body 1, a control component 4 for controlling the movement of the siphon tube 33 is arranged in the control cavity 11, and a water inlet groove 211 connected to the control cavity 11 is opened on the inner wall of the water collecting tank 21, and the control component 4 extends into the water collecting tank 21 and is connected to the siphon tube 33.

[0043] On rainy days, rainwater flows from the road body 1 into the water collecting trough 21 and falls onto the partition plate 31, and then enters the siphon space 34 from the water inlet hole 321. When the liquid level of rainwater in the siphon space 34 is higher than the siphon tube 33, the external pressure is greater than the pressure in the siphon space 34. At this time, a siphon effect is generated in the siphon space 34, and the siphon tube 33 sucks the rainwater in the siphon space 34 into the water collecting trough 21, so that the rainwater is not easy to overflow the water collecting trough 21, thereby accelerating the water permeability of the road body 1; when the rainfall is large, part of the rainwater enters the control chamber 11 through the water inlet trough 211. When the amount of rainwater in the control chamber 11 reaches a certain amount, the control component 4 starts and controls the siphon tube 33 to move in a direction away from the pressure plate 32, thereby accelerating the speed at which the liquid level of rainwater in the siphon space 34 is higher than the siphon tube 33, and accelerating the speed at which the siphon effect is generated in the siphon space 34, thereby further accelerating the water permeability of the road body 1 and improving the water permeability of the road body 1.

[0044] Reference Figure 1 and Figure 2 The control assembly 4 includes a control plate 41, a connecting plate 42, a first connecting rod 43 and a second connecting rod 44. The control plate 41 is slidably connected in the control chamber 11 along the vertical direction. A connecting groove 12 is provided on the inner wall of the control chamber 11. The connecting plate 42 is slidably connected in the connecting groove 12 along the vertical direction. The connecting plate 42 is arranged on a side of the control plate 41 away from the road body 1. A connecting chamber 13 connected to the control chamber 11 is provided on the inner wall of the water collecting tank 21. The first connecting rod 43 is slidably connected in the connecting chamber 13 along the vertical direction. The first connecting rod 43 is fixed on a side of the connecting plate 42 away from the control plate 41. The second connecting rod 44 is slidably connected in the control chamber 11 along the vertical direction. The second connecting rod 44 is fixed to an end of the first connecting rod 43 away from the connecting plate 42, and the second connecting rod 44 is parallel to the connecting plate 42. The second connecting rod 44 extends into the water collecting tank 21 and is fixed to an end of the siphon tube 33 away from the pressure plate 32.

[0045] A reset assembly 23 is provided in the control chamber 11, and the reset assembly 23 includes a first reset spring 231 and a second reset spring 232. One end of the first reset spring 231 is fixed to one end of the control board 41 close to the road body 1, and the other end is fixed to the inner wall of the control chamber 11. One end of the second reset spring 232 is fixed to the side of the connecting plate 42 away from the control board 41, and the other end is fixed to the bottom of the connecting groove 12. A retractable protective cover 24 is provided on the first reset spring 231. One end of the protective cover 24 is fixed to the control board 41, and the other end is fixed to the inner wall of the control chamber 11. The protective cover 24 provides protection for the first reset spring 231, so that rainwater entering the control chamber 11 is not easy to corrode the first reset spring 231.

[0046] When the rainfall is heavy, part of the rainwater enters the control chamber 11 from the water inlet trough 211, and the rainwater accumulates in the storage space formed by the control plate 41 and the inner wall of the control chamber 11. When the weight of the rainwater accumulates to exceed the pulling force provided by the first return spring 231, the weight of the rainwater drives the control plate 41 to move toward the connecting plate 42. At this time, the first return spring 231 is in a compressed state, and the control plate 41 contacts the connecting plate 42 and drives the connecting plate 42 to move in a direction away from the road body 1. At this time, the second return spring 232 is in a compressed state, and the connecting plate 42 drives the first connecting rod 43 and the second connecting rod 44 to move in a direction away from the road body 1. The second connecting rod 44 drives the siphon tube 33 to move in a direction away from the pressure plate 32, so that the speed of the siphon effect in the siphon space 34 is accelerated, which speeds up the speed of the siphon tube 33 to extract rainwater, reduces the possibility of rainwater overflowing the sump 21 when the rainfall is heavy, and further improves the water permeability of the road surface.

[0047] Reference Figure 1 and Figure 2 The road body 1 is provided with an adjusting chamber 14 connected with the water collecting tank 21 and the control chamber 11, and an adjusting assembly 5 is provided in the adjusting chamber 14. The water collecting tank 21 is provided with a power member 22, and the power member 22 is arranged on a side of the partition plate 31 away from the pressure plate 32. The power member 22 extends into the adjusting chamber 14 and is connected with the adjusting assembly 5;

[0048] The power member 22 includes a driving shaft 221 and a driving blade 222. The driving shaft 221 is rotatably connected to the inner wall of the water collecting tank 21. The driving blade 222 is coaxially fixed to the driving shaft 221. The driving shaft 221 extends into the regulating chamber 14 and is connected to the regulating assembly 5.

[0049] The adjusting component 5 includes a follower 51 and a fan blade 52, and the follower 51 and the fan blade 52 are both arranged in the adjusting chamber 14. The inner wall of the control chamber 11 is provided with an adjusting hole 111 connected to the adjusting chamber 14, and the fan blade 52 is arranged opposite to the adjusting hole 111; the follower 51 includes a first driven gear 511, a second driven gear 512 and a transmission belt 513, the first driven gear 511 is coaxially fixed on the driving shaft 221, the second driven gear 512 is rotatably connected to the inner wall of the adjusting chamber 14, the fan blade 52 is coaxially fixed on the rotating shaft of the second driven gear 512, and the diameter of the second driven gear 512 is much smaller than the diameter of the first driven gear 511, so as to facilitate increasing the rotation speed of the fan blade 52.

[0050] The rainwater absorbed by the siphon 33 falls on the driving blades and provides power for the driving blades 222. The driving blades 222 drive the driving shaft 221 to rotate. The rotation of the driving shaft 221 drives the first driven gear 511 to rotate. The first driven gear 511 drives the transmission belt 513 to rotate. The rotation of the transmission belt 513 drives the second driven gear 512 to rotate. The rotation of the second driven gear 512 drives the fan blades 52 to rotate. The fan blades 52 blow air into the control chamber 11 through the adjustment hole 111. When the wind blown by the fan blades 52 passes through the rainwater in the control chamber 11, part of the rainwater follows the wind and re-enters the water collection tank 21 from the water inlet trough 211. In the process of gradually decreasing rainfall, when the weight of the rainwater in the control chamber 11 is less than the resilience of the first return spring 231 Under the action of the rebound force of the first return spring 231, the control plate 41 gradually moves toward the direction close to the road body 1. At the same time, under the action of the second return spring 232, the connecting plate 42 gradually moves toward the direction close to the road body 1. The connecting plate 42 then drives the first connecting rod 43 and the second connecting rod 44 to move toward the direction close to the road body 1. The second connecting rod 44 then drives the siphon tube 33 to move toward the pressure plate 32, so that the speed of the siphon effect in the siphon space 34 gradually slows down, realizing the function of dynamically adjusting the frequency of the siphon tube 33 absorbing rainwater according to the amount of rainfall, reducing the steps of manual intervention, and further reducing the possibility of rainwater overflowing from the sump 21, thereby improving the water permeability of the road surface.

[0051] When the rainfall is heavy, the amount of rainwater absorbed by the siphon tube 33 each time is small, which makes the rotation speed of the drive shaft 221 lower. The lower rotation speed of the drive shaft 221 ultimately makes the rotation speed of the fan blades 52 lower, thereby reducing the amount of rainwater re-entering the sump 21, so that when the rainfall is heavy, the frequency of the siphon effect in the siphon space 34 is maintained within a certain range, reducing the possibility of rainwater overflowing from the sump 21 when the rainfall is heavy.

[0052] Reference Figure 1 A limiting plate 331 is fixed on the siphon tube 33, a limiting groove 311 is provided on the partition plate 31, and the distance between the limiting plate 331 and one end of the siphon tube 33 close to the pressure plate 32 is d1, the vertical height of the water inlet 321 is d1, d1>d2, when the limiting plate 331 conflicts with the limiting groove 311, the fastest speed for generating the siphon effect in the siphon space 34 is reached, and under the action of the limiting plate 331, the siphon effect can always be generated in the siphon space 34, thereby reducing the possibility of rainwater overflowing the water collection tank 21.

[0053] Reference Figure 3A partition net 25 is fixed in the water collection tank 21, and the partition net 25 is arranged on the side of the driving shaft away from the partition plate 31. The partition net 25 and the bottom of the water collection tank 21 form a storage space for storing rainwater. A filter net 28 is fixed at the connection between the water collection tank 21 and the road body 1. When rainwater enters the water collection tank 21, the filter net 28 filters larger impurities, so that the impurities are not easy to block the siphon 33; the siphon 33 draws rainwater into the water collection tank 21, and when the rainwater passes through the partition net 25, the partition net 25 filters the rainwater for the second time, so that smaller impurities are not easy to enter the storage space; and a makeshift hole (not shown in the figure) connected to the city sewer pipe is opened on the side wall of the storage space, so that rainwater is not easy to accumulate too much and overflow the water collection tank 21, and at the same time, the rainwater in the storage space is convenient for the operator to extract and use later.

[0058] The implementation principle of the embodiment of the present application is as follows: on rainy days, rainwater enters the water collection tank 21 and falls on the partition plate 31, and then enters the siphon space 34. When the liquid level of the rainwater in the siphon space 34 is higher than the siphon tube 33, the external pressure is greater than the pressure in the siphon space 34, so that a siphon effect is generated in the siphon space 34. The siphon tube 33 draws rainwater into the water collection tank 21, reducing the possibility of rainwater overflowing the water collection tank 21. At the same time, under the action of the siphon component 3, the speed at which rainwater enters the water collection tank 21 is accelerated, thereby improving the water permeability of the road surface.

[0059] When the rainfall is heavy, part of the rainwater enters the control chamber 11 and exerts pressure on the control component 4. When the amount of rainwater in the control chamber 11 reaches a certain value, the rainwater drives the control component 4 to move, and the control component 4 drives the siphon tube 33 to move in a direction away from the pressure plate 32, thereby accelerating the speed at which the rainwater in the siphon space 34 reaches the height of the siphon tube 33, and accelerating the speed at which the siphon effect is generated in the siphon space 34, further reducing the possibility of rainwater overflowing the sump 21, and further improving the water permeability of the road body 1.
