Description

Technical Field

[0001] The utility model relates to the technical field of rainwater collection and utilization, and particularly relates to a rainwater collection device for the combination of permanent and temporary use at a construction site. Background Art

[0002] The combination of permanent and temporary use means that a certain work is part of a formal building, and at the same time, the functions required by this work are also needed during construction. To avoid repeated setting and reduce consumption, this work is completed first. For example, during the basement decoration construction process, in order to avoid waste, the company first constructs the underground lighting system and powers it on as the temporary power supply during the basement decoration. This avoids the investment in temporary lighting during construction.

[0003] With the development of green construction technology, rainwater collection and utilization have attracted more and more attention from construction enterprises. Therefore, there are more and more rainwater collection devices at construction sites. In the prior art, for example, a rainwater collection device for the combination of permanent and temporary use mentioned in the patent document with the application number CN201821191915.5 preliminarily settles rainwater through a set sedimentation tank and then transfers it to a reservoir.

[0004] There are still certain deficiencies in the above-mentioned prior art rainwater collection device: there are a large number of impurities in the rainwater. Although it can settle slowly under the action of gravity, when the water level in the sedimentation tank during rainfall has reached the height for delivering rainwater to the reservoir, due to the continuous flow of rainwater in the sedimentation tank during rainfall, the newly added rainwater can flow into the reservoir in a short time, and a good effect of settling and filtering impurities cannot be achieved. At the same time, the rainwater in most areas is weakly acidic. Directly using the rainwater to wash the mud on the construction vehicles will cause the accelerated corrosion of metal components such as the vehicle frame. The rainwater collected in this way cannot be used for operations such as car washing, and the scope of application is small. Content of the Utility Model

[0005] The utility model aims at the problems in the prior art and provides a rainwater collection device for the combination of permanent and temporary use at a construction site, which solves the problems that the effect of filtering impurities in rainwater by simply using the sedimentation method in the prior art is not good, and the rainwater is weakly acidic, resulting in the inability to use operations such as car washing during the construction process.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A rainwater collection device for the permanent-temporary combination at the construction site, including a floor drain installed on the roof of the building. The lower end of the floor drain is connected to a sedimentation tank through a pipeline, and the water outlet of the sedimentation tank is connected to a reservoir. There is at least one partition in the sedimentation tank, and several through holes are opened on the partition. A sedimentation filter screen is arranged on each through hole. An acid-base neutralization unit is arranged in the reservoir, and the acid-base neutralization unit is used to release acidic or alkaline substances to neutralize rainwater. Through the arranged sedimentation filter screen, impurities transferred between different chambers in the sedimentation tank can be filtered. At the same time, the arranged acid-base neutralization device can neutralize the pH value of rainwater to be close to neutral, and the corrosion of metal materials is slowed down when using the neutralized rainwater to wash vehicles, equipment and other items.

[0008] Preferably, the sedimentation filter screen is inclined, and the water inlet side of the sedimentation filter screen is inclined downward. By arranging the sedimentation filter screen in an inclined manner, the impurities accumulated on the sedimentation filter screen can fall to the bottom of the sedimentation tank under the action of gravity when the water flow in the sedimentation tank is small, avoiding the water flow blockage at the sedimentation filter screen of the sedimentation tank.

[0009] Preferably, a flow meter and an acid-base detection unit are arranged in the pipeline between the water outlet of the sedimentation tank and the reservoir. Through the arranged flow meter and acid-base detection unit, the amount of acidic or alkaline substances required can be accurately detected, and the acid-base adjustment of rainwater can be further carried out accurately.

[0010] Preferably, a first drain outlet and a second drain outlet are opened on the reservoir. The first drain outlet is connected to the water using device at the external construction site, and the second drain outlet is connected to the municipal pipe network. Through the arranged first drain outlet and second drain outlet, the reservoir can not only be used as a temporary construction water source during construction, but also be permanently used as a drainage mechanism to discharge the preliminarily filtered rainwater into the municipal pipe network after construction, meeting the situation of permanent-temporary combination at the construction site to avoid waste.

[0011] Preferably, a valve is arranged on the pipeline connected to the first drain outlet. Through the arranged valve, it is possible to choose to accumulate water naturally at the second drain outlet for municipal pipe network drainage when water is not needed, avoiding waste of water resources.

[0012] Preferably, drainage filter screens are arranged at both the first drain outlet and the second drain outlet. Through the arranged drainage filter screens, impurities in the water can be further filtered, making the quality of construction water or the water discharged into the municipal pipe network meet the standards.

[0013] It can be seen from the above technical solutions that the advantages of the present utility model are as follows: Through the provided sedimentation filter screen, impurities transferred between different chambers in the sedimentation tank can be filtered. At the same time, the provided acid-base neutralization device can neutralize the pH value of rainwater to be close to neutral, and when using the neutralized rainwater to wash vehicles, equipment and other items, the corrosion of metal materials is slowed down. By setting the sedimentation filter screen obliquely, when the water flow in the sedimentation tank is small, the impurities accumulated on the sedimentation filter screen can fall off to the bottom of the sedimentation tank under the action of gravity, avoiding the water flow blockage at the sedimentation filter screen of the sedimentation tank. Through the provided flowmeter and acid-base detection unit, the amount of acidic or alkaline substances required can be accurately detected, and the acid-base adjustment of rainwater can be further refined. Through the provided first drain outlet and second drain outlet, the reservoir can not only be used as a temporary construction water source during construction, but also be permanently used as a drainage mechanism to drain the preliminarily filtered rainwater into the municipal pipe network after construction is completed, which conforms to the situation of combining permanent and temporary uses at the construction site to avoid waste. Through the provided valve, it is possible to choose to naturally accumulate water at the second drain outlet for municipal pipe network drainage when water is not needed, avoiding waste of water resources. Through the provided drainage filter screen, impurities in the water can be further filtered to make the quality of construction water or the water discharged into the municipal pipe network meet the standards.
