Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated steel structure buildings, and in particular to an energy-saving prefabricated steel structure building for rainwater recycling. Background Art

[0002] Prefabricated steel structures are a type of building structure primarily constructed from steel, using a prefabrication and assembly process. This construction method is highly efficient, environmentally friendly, and flexible, making it widely used in industrial, commercial, and residential applications.

[0003] The document with the prior art publication number CN115874711A provides a steel structure building with an energy-saving prefabricated design for rainwater recycling. According to the different installation parts, two node connection methods with different structures, top node connectors and mid-end node connectors, are designed. The installation of the mid-end node connector needs to be positioned according to the reserved height of the limit clip. Before the steel frame leaves the factory, four sets of limit clips need to be reserved at the required positions on the four sides. The mid-end node connector can be installed in the front, back, left and right four directions according to the installation requirements through the four sets of limit clips, thereby increasing the flexibility of the node connection. The mid-end node connector is mainly used to connect the steel pipes inside the structure, while the top node connector is mainly used to connect the steel beams. The node is designed according to the connection part to increase the convenience of assembly, save more labor during the assembly process, and the node connection is firmer, making the overall more stable and reliable.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By opening a collection trough on the roof of the prefabricated steel structure building, rainwater can be efficiently collected, avoiding rainwater waste. The rainwater can be injected into the pre-buried water tank for storage through the rainwater seat and water pipe. The stored rainwater can be used for irrigation, cleaning, cooling systems, etc., reducing dependence on municipal water supply, helping to save water bills and optimize the use of water resources, which helps to improve the sustainability of buildings. Especially in areas with water scarcity, by reducing dependence on external water sources, it helps to build more resilient and long-term stable buildings, which meets the needs of modern society for sustainable development of buildings;

[0018] 2. By installing an adjustable interception mechanism in the rainwater seat, leaves can be separated when collecting rainwater, thus avoiding poor water flow or water accumulation caused by blockage. When the rainwater seat is retracted, the push rod group drives the adjustable interception mechanism to move up and rotate, causing the intercepted leaves to fall automatically, effectively solving the leaf blockage problem. There is no need for manual cleaning, improving system efficiency and reliability. This not only improves rainwater collection efficiency, but also significantly reduces maintenance costs, enhancing the system's intelligence, environmental protection and sustainability.

[0019] 3. By setting up the impeller seat, the power of falling rainwater can be used as the driving force to drive the water filter seat to rotate, and cooperate with the centrifugal force to filter the sand and dust in the rainwater more finely. At the same time, when the rainwater seat is retracted, it will drive the water filter seat to move away and flip over, so that the internal filter material can be automatically poured out, which not only improves the filtering efficiency and cleaning effect of the system, but also reduces the need for manual maintenance, and enhances the reliability and automation level of the system.

[0033] like Figure 3 As shown, an electric push rod 401 is fixedly connected to one side of the rain water seat 4, and one end of the electric push rod 401 is fixedly connected to the steel structure frame 2. A transmission rack 402 is slidingly provided through the inner wall of the rain water seat 4, and one side of the outer end of the transmission rack 402 is movably contacted with the steel structure frame 2.

[0034] like Figure 4 As shown, the adjustable interception mechanism 5 includes a lifting frame 501, the bottom end of which is rotatably connected to the top end of the push rod assembly 404. Interception mesh panels 502 are rotatably connected to both sides of the lifting frame 501. Two limit rods 503 are fixedly connected to one side of the interception mesh panels 502. A rotating rod 504 is slidably provided between the two limit rods 503. The two ends of the rotating rod 504 are rotatably connected to the rainwater seat 4. The transmission rack 402 moves into the rainwater seat 4, thereby driving the push rod assembly 404 connected to the gear 405 to rotate, so that the push rod assembly 404 can drive the lifting frame 501 to move upward. Under the action of the rotating rod 504, the middle end of the interception mesh panel 502 connected to the limit rod 503 is lifted.

The driving wheel 603 is rotatably connected to the impeller seat 6 via a pin, and the other end of the pin is fixedly connected to a driven wheel 604. When rainwater passes through the impeller seat 6, it drives the impeller 601 to rotate, causing the impeller 601 to rotate the toothed disc 602. At this time, the toothed disc 602 drives the driven wheel 604 connected to the driving wheel 603 to rotate, causing the driven wheel 604 to drive the water filter seat 806 connected to the annular rack 808 to rotate.

Under the action of the fixed rack 704, the transmission wheel 703 can drive the connected universal joint 702 to rotate, so that the universal joint 702 drives the connected reciprocating screw 701 to rotate, so that the reciprocating screw 701 can drive the movable frame 7 to move.

[0037] like Figure 7 、 Figure 8 As shown, the rainwater filtering mechanism 8 includes a rotating ring 801, which is rotatably connected to the movable frame 7. A worm gear 802 is fixedly connected to one end of the rotating ring 801, and a worm 803 is meshingly provided on one side of the worm gear 802. A transmission rod 804 is fixedly connected to one end of the worm 803. A transmission groove 805 is provided on the transmission rod 804, and a guide head 810 is slidingly provided in the transmission groove 805. The guide head 810 is fixedly connected to the rainwater seat 4.

[0038] A water filter seat 806 is rotatably connected within rotating ring 801. The top of water filter seat 806 is in sliding contact with the output end of impeller seat 6. The bottom of water filter seat 806 is in sliding contact with the outer end of water conduit 9, which is fixedly connected to rainwater seat 4. A filter tube 807 is fixedly connected within water filter seat 806. An annular rack 808 is fixedly connected to the outer wall of water filter seat 806, meshing with driven wheel 604. A cleaning block 809 is slidably mounted on the inner wall of filter tube 807. The middle portion of cleaning block 809 slidably engages the inner wall of water filter seat 806. Rubber pads are installed at the top and bottom of water filter seat 806 to improve sealing. Under the action of the guide head 810, the transmission rod 804 with a transmission groove 805 will be driven to rotate, so that the transmission rod 804 can drive the connected worm 803 to rotate, so that the worm 803 can drive the rotating ring 801 connected to the worm wheel 802 to rotate, so that the rotating ring 801 drives the water filter seat 806 to open downward, and at this time the cleaning block 809 in the filter tube 807 automatically slides down under its own weight.

[0039] By providing a collecting trough 301 on the roof 3 of the prefabricated steel structure building, rainwater can be efficiently collected, thus avoiding the waste of rainwater. The rainwater can be injected into the embedded water tank 901 for storage through the rainwater seat 4 and the water pipe 9. The stored rainwater can be used for irrigation, cleaning, cooling systems, etc., thus reducing the dependence on municipal water supply, helping to save water bills and optimize the use of water resources, and helping to improve the sustainability of buildings. In particular, in areas with scarce water resources, by reducing the dependence on external water sources, it helps to build buildings with greater resilience and long-term stability, which meets the needs of modern society for sustainable development of buildings.

[0040] Working principle: On rainy days, the electric push rod 401 is used to drive the rainwater seat 4 to move to the lower end opening of the collecting trough 301 on the roof 3. At this time, the rainwater flowing down will fall into the rainwater seat 4, and then the leaves in the rainwater will be intercepted by the interception mesh plate 502. Then the rainwater will flow into the impeller seat 6, and then flow into the water filter seat 806 through the impeller seat 6 for filtration and then be injected into the embedded water tank 901 through the water guide pipe 9;

[0041] When rainwater passes through the impeller seat 6, it drives the impeller 601 to rotate, causing the impeller 601 to drive the gear plate 602 to rotate. At this time, the gear plate 602 drives the driven wheel 604 connected to the driving wheel 603 to rotate, so that the driven wheel 604 can drive the water filter seat 806 connected to the annular rack 808 to rotate, and quickly filter the rainwater through centrifugal force;

[0042] When the water level sensor in the embedded water tank 901 detects that the water level has reached a preset value, the electric push rod 401 will be controlled to drive the rain water seat 4 to retract. At this time, the transmission rack 402 on the rain water seat 4 will contact the steel structure frame 2, causing the transmission rack 402 to move into the rain water seat 4, thereby driving the push rod group 404 connected to the gear 405 to rotate, so that the push rod group 404 can drive the lifting frame 501 to move upward. Under the action of the rotating rod 504, the middle end of the intercepting mesh plate 502 connected to the limit rod 503 will be driven to rise, and the two ends will be downward, so that the leaves on the intercepting mesh plate 502 can automatically fall down to complete the cleaning;

[0043] At the same time, when the rainwater seat 4 is retracted, under the action of the fixed rack 704, the transmission wheel 703 can drive the connected universal joint 702 to rotate, so that the universal joint 702 drives the connected reciprocating screw 701 to rotate, so that the reciprocating screw 701 can drive the moving frame 7 to move;

[0044] When the movable frame 7 drives the water filter seat 806 to move away, under the action of the guide head 810, the transmission rod 804 with a transmission groove 805 will be driven to rotate, so that the transmission rod 804 can drive the connected worm 803 to rotate, so that the worm 803 can drive the rotating ring 801 connected to the worm gear 802 to rotate, so that the rotating ring 801 drives the water filter seat 806 to open downward. At this time, the cleaning block 809 in the filter tube 807 automatically slides down under its own weight, automatically cleaning the filtered material in the filter tube 807, and then the reciprocating screw 701 continues to rotate, which will drive the water filter seat 806 to reset.
