Technical Field

[0001] The utility model relates to the technical field of retention facilities, in particular to an assembled biological retention facility. Background Art

[0002] In order to achieve the rational use of rainwater, sponge city construction has been gradually promoted in modern urban construction. It means that the city can be like a sponge, with good flexibility in adapting to environmental changes and responding to natural disasters. It can absorb, store, infiltrate and purify water when it rains, and release and utilize the stored water when needed, so as to realize the free migration of rainwater in the city.

[0003] In order to ensure smooth drainage, the drainage time is often preset to ensure that rainwater in a certain area can be drained within the preset time period. However, after long-term use, due to the gradual accumulation of sludge and other pollutants in the soil, the soil permeability decreases, the water retention rate increases, and the drainage time is prolonged, making it impossible to ensure that rainwater can be drained within the preset time. In addition, the layout of sponge facilities needs to be arranged according to the water storage needs and the on-site environment. During the layout process, it is impossible to effectively guarantee the accurate positioning and installation, and the scope of application is limited.

[0004] Therefore, there is an urgent need to provide an assembled biological retention facility to improve and optimize the defects and shortcomings in the above-mentioned prior art. Utility Model Content

[0032] [First embodiment]

[0033] like Figure 1-5 The figure shows an assembled bioretention facility provided by the first embodiment of the utility model, including an overflow well 1, through which heavy rainfall can be discharged when heavy rainfall occurs. Preferably, a water drop level is provided above the overflow well 1. In the initial stage of installation, the water drop level can be used to calibrate whether the excavated installation surface is horizontal; Figure 1 As shown, a slide rail 31 is fixed on the top of the overflow well 1, and a laser level 3 is slidably installed on the slide rail 31. The upper surface of the overflow well is 10 cm away from the light outlet of the laser level. The laser level 3 can slide on the slide rail 31 which is surrounded in a rectangular shape, so that the laser level 3 can calibrate the lowest point elevation around and determine the water inlet position of the biological retention facility. By providing a water drop level and a laser level, the installation accuracy is further guaranteed.

[0034] like Figure 1 As shown, a plurality of water storage modules 2 are arranged on the periphery of the overflow well 1, and the water storage modules 2 are fixedly connected to adjacent water storage modules 2 or the overflow well 1 and are internally interconnected;

[0035] By providing a trigger opening and closing module, the trigger opening and closing module extends into the peripheral soil to provide a capillary drainage belt, and the moisture in the soil is introduced into the trigger cavity through the capillary drainage belt. When the water volume in the trigger cavity increases to the point where the opening and closing block moves, the opening and closing block opens, and the flow port on the top of the water storage module opens, increasing the flow rate of the water storage module. Rainwater can quickly enter the water storage module through the flow port on the top of the water storage module, thereby realizing rapid collection and drainage of rainwater, which is not affected by new installation or long-term use, so as to ensure that the rainwater drainage time is still within the preset time period; in addition, by providing corresponding water storage modules as needed on the periphery of the overflow well, the required water storage modules and quantity can be selected according to different on-site conditions, and the water storage module 2 is fixedly connected to the adjacent water storage module 2 or the overflow well 1 by a fixing member 22, and corresponding positioning components 23 are respectively provided on the top and bottom of the water storage module 2, and each module is fixedly connected and positioned by a fixing member and a positioning component, and the internal communication between the modules and between the modules and the overflow well is ensured, which is convenient to install and has a wide range of applications.

[0036] As a prominent inventive point of this embodiment: a trigger opening and closing module 21 is arranged on the top of the water storage module 2. While absorbing moisture inside the surrounding soil, the trigger opening and closing module 21 can automatically adjust the flow rate of the trigger opening and closing module 21 according to the internal liquid level of the trigger opening and closing module 21.

[0037] like Figure 2-3 As shown, the trigger opening and closing module 21 in this embodiment includes a trigger unit 211 and an opening and closing unit 212.

[0038] A trigger chamber A is provided inside the trigger unit 211. A capillary drainage belt is provided in the trigger chamber A extending into the peripheral soil. The moisture in the soil is introduced into the trigger chamber A through the capillary phenomenon of the capillary drainage belt. A trigger fixed pulley 213 is provided inside the trigger chamber A. The trigger fixed pulley 213 is provided at the top of the trigger chamber A. A trigger block 214 capable of synchronously rising and falling with the liquid level is also provided inside the trigger chamber A. A slow-drain hole is also provided at the bottom of the trigger chamber A. After the initial rain or rain with a small amount of rainfall enters the trigger chamber, it can be gradually and slowly discharged through the slow-drain hole.

[0039] An opening and closing cavity B is provided inside the opening and closing unit 212, and an opening and closing fixed pulley 215 is provided inside the opening and closing cavity B. The opening and closing fixed pulley 215 is provided at the top of the opening and closing cavity B and close to the side of the trigger unit 211. An opening and closing block 216 capable of rotating around a hinge point is also provided inside the opening and closing cavity B. The opening and closing block 216 is provided on the side of the opening and closing cavity B away from the trigger unit 211.

[0040] One end of the connecting rope 217 passes through the trigger fixed pulley 213 and is fixedly connected to the trigger block 214 , and the other end passes through the opening and closing fixed pulley 215 and is fixedly connected to the opening and closing block 216 .

[0041] This setting makes:

[0042] When there is no rainwater in the trigger chamber A, the trigger block 214 is located at a low position in the trigger chamber A due to its own gravity, and the opening and closing block 216 is pulled to a high position in the opening and closing chamber B by the connecting rope 217, thereby closing the flow port of the water storage module 2;

[0043] When there is rainwater inside the trigger chamber A, the trigger block 214 rises synchronously with the buoyancy, the tension on the connecting rope 217 becomes loose, and the opening and closing block 216 falls inside the opening and closing chamber B due to its own weight and rotates clockwise around the hinge point to fall to a low position, so as to realize the opening of the flow port of the water storage module 2;

[0044] In order to close the flow opening of the water storage module 2 when there is no rainwater in the trigger chamber A, the mass of the trigger block 214 needs to be greater than the mass of the opening and closing block 216 to ensure the tensioning effect on the connecting rope 217.

[0045] The specific working process of this embodiment is as follows:

[0046] The trigger module introduces moisture in the soil into the trigger chamber A through the capillary phenomenon by means of the capillary drainage belt. When the water inflow speed is less than or equal to the water outflow speed of the slow drainage hole, there is no rainwater in the trigger chamber A. The trigger block 214 is located at the low position of the trigger chamber A due to its own gravity, and the opening and closing block 216 is pulled to the high position in the opening and closing chamber B by the connecting rope 217, thereby realizing the closure of the flow port of the water storage module 2. Figure 2 and 4 As shown;

[0047] When the water inlet speed is greater than the water outlet speed of the slow discharge hole, water accumulates inside the trigger chamber A, generating buoyancy to offset the gravity of the trigger block 214, and the tension of the connecting rope 217 is reduced, and the tension on the opening and closing block 216 disappears. Under the action of its own gravity, the opening and closing block 216 rotates clockwise around the hinge point to open the flow port of the water storage module 2, thereby increasing the flow rate of the water storage module. Figure 3 and 5 As shown;

[0048] As the flow rate of the water storage module 2 increases, the external soil humidity decreases, and the amount of water stored in the capillary drainage belt also decreases. When the amount of water stored in the capillary drainage belt cannot generate the buoyancy to offset the gravity of the trigger block 214, the trigger block 214 again pulls the opening and closing block 216 through the pulley due to gravity, causing it to rotate counterclockwise to the high position and close.
