Description

Technical Field

[0001] This utility model belongs to the field of sponge city, specifically relating to a building rainfall energy dissipation and drainage system. Background Technology

[0002] With the construction and development of sponge cities, people are paying more and more attention to the utilization of rainwater resources. Among them, the pipes of building drainage systems are usually connected to rain gardens. Rainwater is collected in rain gardens through the drainage system, which is used to irrigate and replenish the rain gardens, and can absorb urban rainwater runoff at the source, reducing the frequency of floods and waterlogging. In order to avoid damage such as cavitation, pulsation, vibration, wear and scouring caused by the water flow of the drainage system, energy dissipation structures need to be installed at the end of the drainage system pipes.

[0003] In related prior art, such as Chinese Patent No. CN219386905U, a roof rainwater energy dissipation well is disclosed, including an integrally formed energy dissipation cavity. The energy dissipation cavity has an inlet and an outlet at both ends, with the inlet connected to a rainwater downpipe. The energy dissipation cavity is equipped with energy dissipation components to block rainwater and offset its kinetic energy. Rainwater is received through the energy dissipation cavity, and the energy dissipation baffles repeatedly block the rainwater, changing its flow direction to absorb the kinetic energy of the rainwater and prevent it from impacting the ground. The roof rainwater energy dissipation well provided by this utility model has the effect of eliminating the kinetic energy of rainwater.

[0004] However, in actual use, since the rain garden can be directly irrigated by rainwater on rainy days, the rainwater flowing out after being dissipated by the energy dissipation cavity cannot be fully absorbed and utilized by the rain garden, resulting in a low utilization rate of rainwater for the above structure. Utility Model Content

[0005] The present invention aims to provide a building rainwater energy dissipation and drainage system to solve the problem of low rainwater utilization rate of existing building rainwater energy dissipation structures mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a building rainfall energy dissipation and drainage system, comprising...

[0007] The energy dissipation box has an energy dissipation chamber and a drainage chamber on its inner side. There is a partition wall between the energy dissipation chamber and the drainage chamber. Both the upper and lower ends of the partition wall are provided with drainage through holes. There are slots on the partition wall, and the slots are connected to the drainage through holes.

[0008] The insert plate is slidably inserted into the energy dissipation box and extends into the slot. The upper end of the insert plate has a through groove, which corresponds to the position of the drain hole located above. The bottom edge of the insert plate is not higher than the bottom edge of the energy dissipation chamber.

[0009] Rainwater pipes are connected to the side wall of the energy dissipation box and communicate with the energy dissipation chamber;

[0010] The baffle is installed inside the energy dissipation chamber and corresponds to the position of the rainwater pipe;

[0011] The drain pipe is installed on the energy dissipation box and is connected to the drain cavity.

[0012] The principle and effects of this technical solution:

[0013] 1. By blocking the drainage hole at the bottom of the partition wall through the lower end of the baffle plate, the rainwater entering the energy dissipation chamber from the rainwater pipe will be temporarily stored in the energy dissipation chamber after being dissipated by the baffle plate. When the water level is too high, it can be discharged through the drainage hole at the top. When drainage is needed, the baffle plate can be raised to open the drainage hole at the bottom of the partition wall, thereby allowing the rainwater in the energy dissipation chamber to be discharged. This achieves the effect of storing rainwater for energy dissipation on rainy days and using it for irrigation as needed on sunny days, thus improving the utilization rate of rainwater.

[0014] 2. The drainage pipes installed in the drainage chamber can serve as a transition and collection point for rainwater overflowing or being discharged from the energy dissipation chamber, thereby reducing the flow rate of rainwater when it reaches the rain garden.

[0015] The present invention is further configured such that: a connecting plate is fixed on the top of the insert plate, the connecting plate abuts against the energy dissipation box, and the horizontal length and width of the connecting plate are both greater than the horizontal length and width of the insert plate; a limiting mechanism is installed on the energy dissipation box, and the limiting mechanism is used to limit the position of the connecting plate relative to the energy dissipation box.

[0016] The principle and effect of this technical solution: By setting the connecting plate, users can more conveniently control the position of the plug plate, and by setting the limiting mechanism, the positional stability of the plug plate during daily use can be ensured, so as to guarantee the water storage effect of the energy dissipation box.

[0017] The present invention is further configured such that: the limiting mechanism includes a limiting unit, the limiting unit includes a fixing block, a limiting plate, a pressure plate and a first spring, the fixing block is fixed on the energy dissipation box, the fixing block has a movable cavity inside, the limiting plate is slidably inserted into the fixing block, the pressure plate is fitted and fixed on the limiting plate, and the pressure plate is slidably engaged in the movable cavity, the first spring is installed in the movable cavity and is located on the side of the pressure plate away from the connecting plate, one end of the limiting plate slides against the top surface of the connecting plate, and the other end of the limiting plate is fixed with a pull ring.

[0018] The principle and effect of this technical solution: By abutting the top surface of the limiting plate and the connecting plate, the limiting plate can be prevented from loosening during daily use. Furthermore, the rebound force of the first spring presses against the pressure plate, ensuring that the limiting plate is stably pressed against the connecting plate without external force, thus further guaranteeing the stability of the limiting plate during use. Moreover, the restriction of the limiting plate on the connecting plate can be released by pulling the pull ring, allowing the energy dissipation box to quickly and conveniently contact the restriction on the connecting plate when drainage and irrigation are required, thereby raising the connecting plate and raising the insert plate to connect the drainage hole located below the partition wall.

[0019] The present invention is further configured such that: the limiting mechanism also includes an elastic unit, the elastic unit includes a guide block, a guide rod and a second spring, the guide block is fixed on the side wall of the energy dissipation box, the guide block has a guide groove, the guide rod is fixed in the guide groove, the end of the connecting plate slides in the guide groove and the connecting plate is slidably fitted on the guide rod, and the second spring is fitted on the guide rod and located below the connecting plate.

[0020] The principle and effect of this technical solution: With the setting of guide block, guide rod and second spring, after the limitation unit on the top surface of the connecting plate is released, the rebound force of the second spring will spontaneously lift the connecting plate, thereby opening the drainage hole located below the insert plate to achieve the effect of drainage and irrigation, so that there is no need to manually lift the connecting plate, which saves more manpower. The guide groove and guide rod of the guide block can guide and limit the movement of the connecting plate.

[0021] The present invention is further configured such that the limiting plate has a guide surface on the side near the connecting plate.

[0022] The principle and effect of this technical solution: By setting the guide surface, when the connecting plate needs to be lowered and reset, the connecting plate can be pressed against the guide surface by simply pressing it, which forces the limiting plate away from the connecting plate, thereby giving way to the downward movement of the connecting plate. There is no need to manually pull the limiting plate. In other words, the setting of the guide surface makes the movement and reset of the connecting plate more convenient and saves manpower.

[0023] The present invention is further configured to include a filter screen and a top cover. The top cover is detachably connected to the energy dissipation box and is located above the energy dissipation chamber. A baffle is fixed to the bottom surface of the top cover, and the filter screen is fixed to the bottom surface of the top cover and abuts against the partition wall.

[0024] The principle and effect of this technical solution: By setting up a filter screen and a detachable top cover, it can filter and intercept gravel and other impurities mixed in with rainwater, and by opening the top cover, the energy dissipation chamber can be maintained and cleaned, which is beneficial for subsequent use.

[0025] The present invention is further configured such that: a connecting rod is fixed to the bottom surface of the top cover, a base plate is fixed to the bottom of the connecting rod, the base plate slides with the energy dissipation chamber, and the bottom edge of the filter screen is connected to the base plate.

[0026] The principle and effect of this technical solution: By setting up the connecting rod and the base plate, the impurities intercepted by the filter screen in the energy dissipation chamber can accumulate on the base plate. Then, by removing the top cover, the base plate can be taken out along with the connecting rod, thus achieving the effect of convenient cleaning and facilitating subsequent maintenance and use.
