Description
Technical Field
[0001] The utility model relates to the technical field of municipal construction, and in particular to a rainwater collection device for the reconstruction of old residential areas. Background Art
[0002] At present, there are a large number of old residential areas in cities. They face various problems due to their early construction, outdated facilities, and incomplete functions. The drainage system of old residential areas is one of the typical ones. The main problems include: unreasonable original design, aging and damage of pipes, lack of maintenance, etc. These problems often lead to insufficient drainage capacity. When it rains, rainwater from the roof and roof flows directly to the road along the roof sewer pipes, which easily causes water accumulation on the road, which not only affects people's normal life, but also wastes water resources. Summary of the invention
[0003] In view of the deficiencies in the prior art, the utility model proposes a rainwater collection device for the renovation of old residential areas which has a wide range of applications and is easy to use.
[0004] The rainwater collection device for renovation of old residential areas described in the present application comprises a rainwater collection part, a rainwater storage part and a pipe connecting the rainwater collection part and the rainwater storage part;
[0005] The rainwater collecting part comprises a flexible upper part and a rigid lower part which are connected and fixed to each other, the rigid lower part is detachably connected with a filter screen A, the mesh diameter of the filter screen A is d, and satisfies 0.1cm≤d≤0.5cm, a pipe inlet is opened at 2 / 3 of the height of the rigid lower part, a filter screen B is provided at the pipe inlet, the mesh diameter of the filter screen B is D, 1cm≤D≤4cm, and a binding mechanism is provided on the outer surface of the rainwater collecting part;
[0006] The binding mechanism includes a rotating handle and a binding rope, one end of the binding rope is fixed to the outer surface of the rigid lower part, and the other end of the binding rope is fixed to the rotating shaft of the rotating handle; after the binding rope is wrapped around the flexible upper part, both ends of the binding rope pass through the clamping ring provided on the flexible upper part and extend to the rigid lower part; the rotating handle is rotatably connected to the outer surface of the rigid lower part.
[0007] The flexible upper part of the rainwater collection device described in the present application can match various models and thicknesses of house drainage pipes. The entire rainwater collection part is fixedly connected to the end of the original house drainage pipe by a binding rope. Because the mesh diameter of the filter A is much smaller than the mesh diameter of the filter B, when it starts to rain, the rainwater can still flow to the ground through the filter A. When the rainwater gradually increases and the water flow in the original house drainage pipe increases, the rainwater cannot flow from the filter A to the ground in time. The water level in the rainwater collection part gradually rises, rising to the entrance of the pipe and flowing through the pipe into the rainwater storage part. When the water flow is small, the rainwater flowing to the ground can flush the device described in the present application on the one hand, and this part of the rainwater will not enter the rainwater storage part. At the same time, it will not cause too much drainage pressure on the original drainage system in the old community.
[0008] Furthermore, the rotating shaft and the binding rope of the rainwater collection device for renovation of old residential areas described in the present application are fixed to one side of the rotating shaft and are provided with mutually matching saw teeth. The mutually matching saw tooth structure can more conveniently and stably tighten or loosen the binding rope, which is convenient for the installation and disassembly of the rainwater collection device described in the present application.
[0009] Furthermore, the shaft of the rainwater collection device for renovation of old residential areas described in the present application is provided with a bearing, the shaft end of the shaft close to the outer surface of the rigid lower part is provided with at least one protrusion, the outer surface of the rigid lower part is provided with a circular groove that enables the shaft to rotate, and the bottom of the circular groove is provided with a groove that matches the shaft end. The above circular groove can ensure that when the shaft end is located in the circular groove, the entire shaft can rotate freely, thereby tightening or loosening the binding rope, and when the binding rope is tightened or loosened and the shaft does not need to be rotated anymore, the shaft is pressed so that the shaft end is stuck in the groove and fixed.
[0010] Furthermore, a sewage cleaning port and a sewage trough capable of pumping sewage out from the sewage cleaning port are provided at the bottom of the rainwater storage portion of the rainwater collection device for the renovation of old communities described in the present application, and an isolation plate is provided at a position above the upper edge of the sewage trough in the rainwater storage portion, the isolation plate comprises a group A plate and a group B plate capable of horizontally moving relative to the group A plates, the group B plates being connected to a handle capable of controlling the translation of the group B plates; when the group B plates are away from the group A plates, they form an isolation plate with the group A plates capable of completely separating the rainwater storage portion into two parts. The specific structure of the isolation plate allows the B group of plates to be close to the A group of plates and overlap the A group of plates above or below during normal water storage, so that the sewage trough and the interior of the rainwater storage part are connected, and the rainwater in the rainwater storage part can settle on its own. After one water storage is completed, the B group of plates is moved by the handle so that the B group of plates is away from the A group of plates and forms an isolation plate with the A group of plates, isolating the space between the rainwater storage part and the sewage trough, and then the sewage trough is drawn out through the sewage cleaning port, and the sediment in the sewage trough and the sewage trough itself are cleaned.
[0011] Furthermore, the pipeline of the rainwater collection device for the renovation of old residential areas described in the present application is a flexible pipe, and can be detachably connected to the rainwater collection part and the rainwater storage part.
[0012] Furthermore, an overflow port is provided near the top of the rainwater storage portion of the rainwater collection device for renovation of old residential areas described in the present application.
[0013] Furthermore, a water level monitor and an alarm are provided on the upper part of the overflow port of the rainwater collection device for renovation of old residential areas described in the present application. When the stored rainwater exceeds the overflow port and reaches the height of the water level monitor, the alarm sounds an alarm, and the staff can connect the pipe to a new rainwater storage part.
[0014] The beneficial effects of the utility model include:
[0015] The utility model provides a rainwater collection device for the renovation of old residential areas. On the one hand, the flexible upper part can match house drainage pipes of various models and thicknesses, and the entire rainwater collection part is fixedly connected to the end of the original house drainage pipe by a binding rope, so that the rainwater in the original house drainage pipe in the old residential area can be conveniently collected and stored in the rainwater storage part.
[0016] On the other hand, the mesh diameter of filter A is much smaller than that of filter B, so when it starts to rain, rainwater can still flow to the ground through filter A. However, when the amount of rainwater gradually increases and the water flow in the original house drainage pipe increases, the rainwater cannot flow to the ground from filter A in time, and the water level in the rainwater collection part gradually rises, rising to the entrance of the pipe and flowing through the pipe into the rainwater storage part. When the water flow is small, the rainwater flowing to the ground can flush the device described in this application, and this part of the rainwater will not enter the rainwater storage part. At the same time, it will not cause too much drainage pressure on the original drainage system in the old community.
[0017] In addition, the specific structure of the isolation plate can ensure the normal operation of the rainwater storage part while conveniently cleaning the sewage tank at the bottom.
[0018] The rainwater collected by the rainwater collection device described in the present application can be used in the pond in the courtyard of the community or for landscape water, which not only saves water resources but also beautifies the environment. BRIEF DESCRIPTION OF THE DRAWINGS
