This utility model belongs to the field of urban water conservation and discloses an integrated system for rainwater harvesting and greywater reuse in buildings. It includes a rainwater harvesting system comprising a rainwater tank, rainwater collection pipes, rainwater downpipes, and a rainwater outlet pipe. The rainwater tank is installed within the building body, the rainwater collection pipes are fixed to the top of the building body and connected to the rainwater tank, and a rainwater overflow pipe is installed inside the rainwater tank. The rainwater downpipes are installed on the side walls of the building body, and the rainwater overflow pipes are connected to the rainwater downpipes. The rainwater outlet pipe is installed on the side wall of the rainwater tank. A greywater system is also included. Rainwater is collected from the top floor of the building body through the rainwater collection pipes, and then connected to the greywater system through the rainwater outlet pipes. This allows the rainwater collected by the building body to be reused for indoor washing, avoiding the situation where rainwater collected by the building cannot be fully utilized by the rain garden, thus improving the utilization rate of rainwater.

The utility model discloses a rainwater flower box with water purification, storage and release functions relates to rainwater flower box technical field, including rainwater tank, the water inlet, overflow port and the access hole are set gradually from top to bottom in the one side of rainwater tank, and the water inlet is fixedly connected with the water taking pipe of the other side of rainwater tank, the inside fixed mounting of water inlet has the water inlet pipe, the water inlet pipe one end extends to the inside of rainwater tank, and the other end of water inlet pipe is provided with purification subassembly. The utility model discloses a third connecting pipe, overflow port and overflow pipe can be used in the process of rainwater tank, when the water inlet pipe is stored in the inside of rainwater tank, because the height value of third connecting pipe is less than the height value of rainwater tank, with the first connecting pipe continuously stored in the inside of rainwater tank, third connecting pipe will pour the water overflowed in rainwater tank in the soil of flower plant, reach the purpose of automatic irrigation to flower plant, and bring the convenience for the use of rainwater tank.

The utility model provides a folding arm square umbrella, including support stand, still include: lifting structure, lifting structure sets up on support stand, support arm structure, support arm structure sets up on support stand and lifting structure, lifting structure ascends and drives folding arm structure to open. Through motor positive rotation drives fine turning screw rod rotation, it is convenient to make the whole folding arm square three better automatic unfolding and folding storage. The motor of the present application is arranged at the top of the whole folding arm square umbrella, which facilitates increasing the sun-shading area available below the folding arm square umbrella. The motor can be easily disassembled and repaired by removing the motor chamber cover. The collected rainwater in the rainwater tank is discharged through the water outlet pipe, which facilitates the installation of the water outlet pipe on the folding arm square umbrella and effectively discharges the rainwater falling into the interior.

This utility model belongs to the field of stormwater culvert technology. It discloses an intelligent stormwater culvert for intercepting sewage, comprising a culvert body. A hydraulically operated, bottom-opening weir gate is installed near the center of the culvert body. The hydraulically operated, bottom-opening weir gate divides the culvert body into a first chamber and a second chamber from left to right. A floating baffle is installed inside the first chamber near the hydraulically operated, bottom-opening weir gate. This stormwater culvert has an intelligent diversion function. Compared to traditional interception wells, it not only intercepts sewage on sunny days but also automatically opens or closes the gate according to different conditions based on parameters measured by water quality analyzers, rain gauges, and level gauges, thus achieving intelligent sewage interception. This effectively and thoroughly separates rainwater and sewage. Utilizing the diversion well approach in a stormwater culvert can effectively intercept sewage in the culvert on sunny days, greatly reducing the frequency of combined rainwater and sewage overflows during rainy days. It can play a significant role in the treatment of black and odorous water bodies and the control of river water quality.
