DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] The embodiment of the present application provides a device for collecting rainwater in a beam yard and recycling water for box beam maintenance, which can solve the technical problem in the prior art that waste water cannot be effectively collected during spray maintenance of prefabricated beams, resulting in waste of water resources and adverse effects on the construction environment.

[0027] Figure 1It is a front view of a device for collecting rainwater in a beam yard and recycling water for box beam maintenance provided in an embodiment of the present application. The device for collecting rainwater in a beam yard and recycling water for box beam maintenance in the present application includes a water collection system and a spraying system. The water collection system includes a drainage ditch 1 which is arranged on the ground on both sides of a pedestal 8 in an inclined shape for collecting and draining wastewater. A protrusion 101 is arranged at the bottom of the drainage ditch 1 for preliminary filtering of impurities in the wastewater. The outflow end of the drainage ditch 1 is connected to a water reservoir 2 located below the ground plane for collecting wastewater flowing out of the drainage ditch 1 and stratifying and purifying the wastewater; the spraying system includes a spraying pipe 3 which is arranged on the side of the pedestal 8 and extends to the top of the pedestal 8. A plurality of spraying ports 4 with adjustable spraying directions are arranged on the side of the spraying pipe 3 facing the pedestal 8. A water supply hose 5 connecting the water reservoir 2 and the spraying pipe 3 is arranged at the bottom of the water reservoir 2. A temperature and humidity sensor 6 electrically connected to the spraying port 4 is arranged on the spraying pipe 3.

[0028] The pedestal 8 is used to place prefabricated beams. The drainage ditches 1 arranged on the ground on both sides of the pedestal 8 can collect the wastewater flowing out during spraying and maintenance work and drain it into the water reservoir 2, which is convenient for multiple recycling and can also prevent the wastewater from flowing out and causing adverse effects on the construction environment. At the same time, the drainage ditch 1 can also collect rainwater in rainy and snowy weather and drain it for storage to save resources. Furthermore, in order to avoid the drainage ditch 1 causing obstacles to the construction workers during spraying operations, in one embodiment of the present application, the top surface of the drainage ditch 1 is consistent with the ground elevation.

[0029] The drainage ditch 1 is arranged on both sides of the pedestal 8. The wastewater left on the pedestal 8 may carry some impurities such as stones and then enter the drainage ditch 1. At this time, the protrusion 101 arranged at the bottom of the drainage ditch 1 can block the impurities deposited at the bottom when the wastewater flows, so as to complete the preliminary screening of the wastewater. As an optional embodiment, the setting form of the protrusion 101 includes but is not limited to serrated, corrugated or stepped shapes, which can block large impurities in the wastewater to complete the preliminary filtration, and there is no specific limitation in the present application.

[0030] The water reservoir 2 is arranged below the horizon and is located at the drainage terminal of the drainage ditch 1. The water reservoir 2 is divided into multiple layers, and each layer will purify the wastewater to different degrees until the wastewater reaches the spraying requirement. At the same time, the top of the water reservoir 2 is open, which can also assist in collecting rainwater. However, at the same time, the opening of the water reservoir 2 will also pose a safety hazard. Some construction sites have a large number of personnel, which may easily cause people to fall into the water. Therefore, as an optional embodiment, a cover plate can be added to the top of the water reservoir 2. The cover plate can be set to a grid shape according to actual use requirements. While playing a protective role, it will not hinder the process of collecting rainwater in the water reservoir 2.

[0031] The spray pipe 3 is arranged on one side of the pedestal 8. In cooperation with the spray port 4 arranged on the spray pipe 3, the waste water in the water reservoir 2 can be discharged and sprayed toward the pedestal 8 to complete the use process of water source circulation. The water supply hose 5 connects the spray pipe 3 and the water reservoir 2. Since the water reservoir 2 is arranged below the horizon, the water supply hose 5 also needs to be buried in advance.

[0032] The spraying port 4 can flexibly adjust the spraying direction according to the area of ​​the prefabricated beam or other spraying requirements. The methods for adjusting the spraying direction include but are not limited to providing a hollow swing arm, a universal water outlet, etc. at the connection end between the spraying port 4 and the spraying pipe 3. The spraying port 4 with adjustable spraying direction is a commonly used component in the prior art and will not be described in detail here. Furthermore, in order to accurately increase the humidity in the spraying area and improve the spraying efficiency, an atomizer can also be added to the spraying port 4. The atomized spraying water is more delicate and uniform, and is more easily absorbed by the prefabricated beam.

[0033] The temperature and humidity sensor 6 is electrically connected to the spray port 4, and the sensing surface of the temperature and humidity sensor 6 faces the base 8 to sense the dryness and temperature of the prefabricated beam on the base 8, and accurately control the amount of water sprayed by the spray port 4. The minimum dryness threshold and the maximum temperature threshold of the temperature and humidity sensor 6 can also be set in advance. When the dryness of the surface of the prefabricated beam is lower than the minimum threshold and higher than the maximum temperature threshold, the spray port 4 is controlled to automatically start spraying or increase the amount of water sprayed.

[0034] Furthermore, one end of the drainage ditch 1 away from the water reservoir 2 is higher than the end of the drainage ditch 1 close to the water reservoir 2, so as to facilitate the direct drainage of the wastewater collected in the drainage ditch 1 into the water reservoir 2. At the same time, for the safety of the operators, a cover plate can also be set on the drainage ditch 1 to prevent the operators from accidentally stepping on it. The inner wall of the drainage ditch 1 is sprayed with waterproof material or paved with waterproof floor tiles to prevent the wastewater from infiltrating and causing a decrease in the wastewater circulation rate.

[0035] Furthermore, Figure 2 An overhead view of a drainage ditch 1 in a device for collecting rainwater in a beam yard and recycling water for box beam maintenance provided in an embodiment of the present application, wherein the drainage ditch 1 includes a plurality of secondary drainage ditches 103 arranged on the ground on both sides of a pedestal 8, and a main drainage ditch 102 is arranged at the outflow end of the secondary drainage ditch 103. The main drainage ditch 102 is also arranged on the ground near the pedestal, but needs to be separated from the pedestal 8 by a certain distance to leave operating space for the staff. The main drainage ditch 102 is connected to the water reservoir 2. There may be multiple pedestals 8 at the operation site, and the number of secondary drainage ditches 103 arranged on both sides of the pedestal 8 will also increase exponentially. At the same time, the setting positions of some pedestals 8 may be relatively messy. If the secondary drainage ditch 103 is directly connected to the water reservoir 2, the setting position of the water reservoir 2 will be limited to a great extent, and chaos will also be caused at the work site. Therefore, adding a main drainage ditch 102 can integrate the drainage routes of multiple secondary drainage ditches 103, which will help to facilitate the setting of the water reservoir 2 and improve the cleanliness of the site.

[0036] Furthermore, an isolation net 104 is provided at one end of the secondary drainage ditch 103 connected to the main drainage ditch 102. As the first water collection channel, the secondary drainage ditch 103 will inevitably carry various impurities. The protrusion 101 in the secondary drainage ditch 103 can block some large and heavy objects, but it cannot clean up impurities such as fallen leaves floating on the water surface. When the wastewater in multiple secondary drainage ditches 103 is collected in the main drainage ditch 102, a large amount of floating objects will also be collected in the main drainage ditch 102, affecting the purification efficiency of the water storage tank 2 in the later stage. Therefore, the isolation net 104 provided at one end of the secondary drainage ditch 103 connected to the main drainage ditch 102 can effectively block floating objects and ensure that the wastewater entering the main drainage ditch 102 does not have obvious large impurities. As an optional embodiment, the isolation net 104 is detachably arranged in the secondary drainage ditch 103 to facilitate later cleaning and replacement.

[0037] Furthermore, the water reservoir 2 includes a sedimentation tank 201 located at the top of the water reservoir 2 for preliminary filtration of wastewater, a purification tank 202 arranged below the sedimentation tank 201 for secondary purification of wastewater seeping from the sedimentation tank 201, and a clean water tank 203 arranged below the purification tank 202 for storing purified wastewater. A filter plate 2011 is provided at the bottom of the sedimentation tank 201, and a purifier 2021 is provided at the bottom of the purification tank 202.

[0038] Figure 3 A schematic diagram of the structure of a water reservoir 2 in a device for collecting rainwater in a beam yard and recycling water for box beam maintenance provided in an embodiment of the present application. The water reservoir 2 has at least three layers. The water flowing out of the main drainage ditch 102 will first enter the sedimentation tank 201, and will be preliminarily filtered by a filter plate 2011 arranged at the bottom of the sedimentation tank 201. The filter plate 2011 is provided with mesh through holes, and the diameter of the mesh through holes is smaller than the diameter of the isolation net 104, so as to filter small particles of wastewater. The sedimentation tank 201 is mainly used for filtration, and the wastewater will directly pass through the filter plate 2011 into the purification tank 202, so the depth of the sedimentation tank 201 is set slightly shallow, which can also facilitate the staff to clean the filter plate 2011.

[0039] After fine filtration in the sedimentation tank 201, the wastewater enters the purification tank 202. The filtered wastewater still contains various bacteria or unfilterable fine impurities. Long-term sedimentation may clog the water supply hose 5 and the spray port 4. Therefore, the purifier 2021 set in the purification tank 202 can perform secondary purification on the wastewater. The water source purification device is a commonly used component in the prior art and will not be described in detail here.

[0040] The wastewater after secondary purification has become clean water that meets the spraying needs, and then continues to infiltrate into the clean water tank 203. The clean water tank 203 is mainly used for storage. Therefore, the depth of the clean water tank 203 can be deepened accordingly. An outlet pipe 7 is provided at the bottom of the clean water tank 203. A water pump 701 is provided at the water outlet end of the outlet pipe 7. The water pump 701 connects the outlet pipe 7 and the water supply hose 5. The water pump 701 draws out the clean water stored in the clean water tank 203, flows through the outlet pipe 7, enters the water supply hose 5, and then enters the spraying pipe 3.

[0041] Figure 4 A schematic diagram of the structure of a spray pipe 3 in a device for collecting rainwater in a beam yard and recycling water for box beam maintenance provided in an embodiment of the present application is provided. The spray pipe 3 includes a vertical pipe body 301 vertically arranged on one side of a pedestal 8 and a plurality of branch pipe bodies 302 located on the top of the vertical pipe body 301 and extending to above the pedestal 8. The branch pipe body 302 forms a frame body with the same length and width as the pedestal 8, and the spray port 4 is arranged on the branch pipe body 302.

[0042] Since the water circulation device in the present application is arranged outdoors and is often exposed to rain, snow or strong sunshine, in order to increase the service life of the spray pipe 3, the spray pipe 3 is a metal pipe, and the vertical pipe body 301 is the spray main pipe body with a relatively thick diameter to meet the water volume requirements of multiple spray ports 4. The branch pipe bodies 302 are interconnected and form a frame with the same length and width as the base 8 on the top of the base 8. At the same time, multiple branch pipe bodies 302 can also be added at the center position of the frame to increase the spraying coverage area of ​​the branch pipe body 302.

[0043] One end of the water supply hose 5 is connected to the water pump 701, and the other end is connected to the vertical pipe body 301. A booster pump 501 is arranged on the water supply hose 5. The clean water tank 203 is arranged below the horizon. When the clean water enters the spray pipe 3, it needs to flow upward. Therefore, a booster pump 501 is arranged on the water supply hose 5 to enhance the water pressure and ensure the normal circulation of clean water.

[0044] The water recycling device in the present application can collect the wastewater and natural rainwater flowing down from the pedestal 8, and drain them into the water reservoir 2 through the drainage ditch 1, and perform preliminary filtration of large particles on the wastewater through the protrusion 101 and the isolation net 104 at the bottom of the secondary drainage ditch 103, and then enter the water reservoir 2 through the main drainage ditch 102. The water reservoir 2 is provided with a sedimentation tank 201 and a purification tank 202, which can finely filter and purify the wastewater to prevent impurities in the wastewater from entering the spraying pipe 3 and causing blockage. The steerable spray port 4 can adjust the spraying direction according to the area of ​​the prefabricated beam to ensure uniform spraying. The temperature and humidity sensor 6 electrically connected to the spray port 4 can adjust the water output of the spray port 4 according to the temperature and humidity of the surface of the prefabricated beam. Then the wastewater enters the water reservoir 2 again through the drainage ditch 1 for purification, and is recycled many times. While improving the spraying efficiency, it saves resources and reduces the spraying cost, and can also ensure the cleanliness of the work site. The overall structure is simple and practical, and can meet the spraying needs of most prefabricated beams.
