Description

Technical Field

[0001] The utility model relates to the technical field of rainwater treatment, in particular to a rainwater retention ecological pool. Background Art

[0002] A rainwater retention pond is a facility for rainwater collection and utilization, designed to reduce pollutants in rainwater runoff through natural processes and provide a sustainable irrigation water source. This type of pond usually includes a low-lying area for collecting rainwater, which is designed as a natural system that can infiltrate and filter rainwater. The rainwater retention pond is an innovative rainwater management solution that is environmentally friendly, sustainable and multifunctional. With people's increasing attention to the ecological environment and sustainable development, this facility will have increasingly important application value in urban planning and construction.

[0003] According to a Chinese patent with the authorized publication number CN210439424U, a bioretention device for removing pollutants is disclosed. Through the reasonable arrangement of multiple layers of structures such as aquifers, bark covering layers, vegetation and planting soil layers, artificial filler layers, and sand and gravel layers, and the use of different media for each layer of filler, the effect of removing pollutants in rainwater, such as grease, heavy metals and nutrients, is improved. In actual use, the above scheme generally directly carries out multiple layers of filler inside the rainwater retention ecological pool, and generally no structure for supporting effect is set inside. As the use time increases, the filler may collapse under the continuous penetration of water flow, resulting in failure to achieve the expected effect of rainwater treatment, reducing the practicality of the existing rainwater retention ecological pool.

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0029] See also Figures 1 to 3 The utility model provides a technical solution: a rainwater retention ecological pool, comprising an ecological pool wall 1, a covering layer 2, a soil layer 3, a filler layer 4, a gravel layer 5, a drainage pipe layer 6, a sand layer 7, an overflow well 8, a plant vegetation layer 10, a reinforcing component 200 installed inside the ecological pool wall 1 to improve the internal structural strength of the ecological pool wall 1, and an installation component 300 installed on the top of the overflow well 8 to ensure that the overflow well 8 can be used normally;

[0030] Through the coordinated use of the ecological pool wall 1, the covering layer 2, the drainage pipe layer 6, the overflow well 8, and the reinforcement component 200, in actual use, the strength of the structure in the rainwater retention ecological pool can be effectively improved, thereby effectively avoiding the increase in use time at any time. When the filler collapses under the continuous penetration of the water flow, it is ensured that the expected rainwater treatment effect can be achieved. In addition, through the use of the installation component 300, when the manhole cover is blocked by silt, weeds and other materials, the manhole cover can be effectively removed for cleaning, ensuring that the expected use effect can be achieved, thereby improving the practicality of the rainwater retention ecological pool.

[0031] In this embodiment, the reinforcement component 200 is a structure used to improve the internal structural strength of the ecological pool wall 1.

[0032] like Figure 1 and Figure 2 As shown, the reinforcement component 200 includes a first filter screen 201 slidably connected to the outside of the overflow well 8, a second filter screen 202 slidably connected to the outside of the overflow well 8, four fixing seats 203 respectively fixed to the top of the first filter screen 201 and the second filter screen 202, a sleeve ring 204 sleeved on the outside of the fixing seat 203, a connecting rod 205 fixed on the outside of the sleeve ring 204, an arc plate 206 fixed to one end of the connecting rod 205 close to the overflow well 8, and a fastening screw 207 threadedly connected to the inside of the arc plate 206.

[0033] It should be noted that the vegetation layer 10, the covering layer 2, the soil layer 3, the first filter screen 201, the filler layer 4, the second filter screen 202, the gravel layer 5, the drainage pipe layer 6, and the sand and soil layer 7 are arranged in sequence from top to bottom inside the ecological pool wall 1 to ensure that while strengthening the internal structural strength of the ecological pool wall 1, it can also achieve the expected effect of rainwater filtration.

[0034] In addition, a drain pipe is fixed inside the overflow well 8, and one end of the drain pipe away from the overflow well 8 is located outside the ecological pool wall 1, ensuring that the water in the overflow well 8 can be discharged through the drain pipe.

[0035] In addition, the packing layer 4 is filled with sawdust. In order to improve the firmness and permeability of the packing layer 4, gravel can also be filled in the packing layer 4. When rainwater infiltrates, a proper amount of rainwater can be stored for use by plants in the ecological retention pond.

[0036] In this embodiment, the installation assembly 300 is a structure for installing the manhole cover of the overflow manhole 8.

[0037] like Figure 1 and Figure 3 As shown, the installation assembly 300 includes an annular plate 301 fixed to the outside of the overflow well 8, a manhole cover body 9 slidably connected to the top of the annular plate 301, two fixed blocks 302 fixed to the bottom of the manhole cover body 9, two adjustment chambers 303 opened inside the annular plate 301, a movable plate 304 slidably connected to the inside of the adjustment chamber 303, a fixed rod 305 fixed inside the movable plate 304, and two springs 306 respectively fixed to the opposite sides of the two movable plates 304.

[0038] It should be noted that the opposite sides of the two fixing rods 305 successively penetrate the annular plate 301, the adjustment cavity 303, the movable plate 304 and the fixed block 302 and extend to the interior of the fixed block 302 to be plugged with the fixed block 302. The bottom of the fixed block 302 penetrates the annular plate 301 and extends to the bottom of the annular plate 301, ensuring that the manhole cover body 9 can be fixedly installed by the fixing rods 305 and the fixed block 302.

[0039] In addition, circular plates are fixed to the opposite ends of the two fixing rods 305, and the diameter of the circular plates is larger than the diameter of the fixing rods 305, ensuring that the fixing rods 305 can be effectively adjusted through the circular plates. The spring 306 is located on the outside of the fixing rods 305, ensuring that the spring 306 can play the expected elastic effect.

[0040] In addition, the width of the movable plate 304 is equal to the width of the adjusting chamber 303, and the height of the movable plate 304 is equal to the height of the adjusting chamber 303, so that the movable plate 304 can slide more stably in the adjusting chamber 303. Sealing rings are fixed on the opposite sides of the two circular plates. Through the coordinated use of the movable plate 304 and the sealing ring, water vapor can be effectively prevented from entering the adjusting chamber 303, thereby effectively improving the service life of the spring 306.

[0041] The working principle of the above embodiment is:

[0042] When in use, the overflow well 8 is first set inside the ecological pool wall 1 by pouring or the like, and then a sand layer 7, a drainage pipe layer 6 and a gravel layer 5 are laid inside the ecological pool wall 1, and then the second filter screen 202 is set on the top of the gravel layer 5, and then the connecting rod 205 and the arc plate 206 are adjusted by the sleeve ring 204, and then the arc plate 206 is closely contacted with the outside of the overflow well 8, and then the arc plate 206 is fixed to the overflow well 8 by tightening the screws 207, so as to fix the second filter screen 202 to the overflow well 8, and then the packing layer 4 is laid on the top of the second filter screen 202, and then the first filter screen 201 is set on the top of the packing layer 4, and then the above operation is repeated to fix the first filter screen 201 to the overflow well 8. , and then the soil layer 3, the covering layer 2 and the plant vegetation layer 10 are laid on the top of the first filter screen 201 in turn, so that the strength of the internal structure of the ecological pool wall 1 can be effectively improved under the coordinated use of the overflow well 8, the second filter screen 202 and the first filter screen 201. When the manhole cover body 9 needs to be removed for cleaning, the two fixing rods 305 are pulled to the left and right sides respectively to separate the fixing rods 305 from the fixing blocks 302, so that the manhole cover body 9 can be effectively removed. At this time, the spring 306 is in a compressed state under the action of the movable plate 304. After the manhole cover body 9 is cleaned, the fixing rod 305 is released, and under the action of the restoring elastic force of the spring 306, the fixing rod 305 and the fixing block 302 are reinserted, so that the manhole cover body 9 is fixed again.

[0043] Compared with the prior art, the rainwater retention ecological pond, through the coordinated use of the ecological pond wall 1, the covering layer 2, the drainage pipe layer 6, the overflow well 8, the first filter screen 201 in the reinforcement component 200, the connecting rod 205 and the arc plate 206, can effectively improve the strength of the structure in the rainwater retention ecological pond during actual use, thereby effectively avoiding the possibility of filler collapse under the continuous penetration of water flow as the use time increases at any time, thereby ensuring that the expected rainwater treatment effect can be achieved, and the coordinated use of the annular plate 301 and the fixing rod 305 in the installation component 300, when the manhole cover is blocked by silt, weeds and other materials, the manhole cover can be effectively removed for cleaning, ensuring that the expected use effect can be achieved, thereby improving the practicability of the rainwater retention ecological pond and solving the problem of low practicability of the existing rainwater retention ecological pond.
