[0002] With the widespread promotion of the concept of energy conservation and emission reduction, it has penetrated into all areas of national life. In the field of construction, the concept of energy conservation and emission reduction is mainly reflected in how to reduce the use of electricity and how to improve the full utilization of heat, ignoring the contribution of full utilization of natural water sources to energy conservation and emission reduction. Occasionally, the design of natural water source utilization is only to collect and reuse rainwater for greening irrigation, etc., with limited energy-saving effects. Similarly, in the field of construction, the application of energy conservation and emission reduction is usually manifested as saving the use of electricity rather than saving the use of water resources. However, in the field of construction, the use of water resources is large, but the water quality requirements are not high. Therefore, rainwater can be collected and reused in areas with suitable natural environmental conditions, thereby reducing the waste of domestic water. Utility Model Content

The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0018] A building construction energy-saving drainage system comprises a water inlet component 1, a guide pipe 3, a power generation pipe 4, a water storage tank 6 and a plurality of water pipe sections 2. A water pipe section 2 is fixedly connected to the lower end of the water inlet component 1, the lower end of the water pipe section 2 is communicated with the guide pipe 3, the guide pipe 3 is inserted into the upper end of the power generation pipe 4, the lower end of the power generation pipe 4 is communicated with another water pipe section 2 through a connecting pipe 7, the lower end of the other water pipe section 2 is communicated with the water storage tank 6 through a bend pipe 5, a power generation component is embedded in the power generation pipe 4, water flows through the water inlet component 1 after being converged and flows into the drainage system, the water flows through the guide pipe 3 and is concentratedly guided to flush on the power generation component to cause the power generation component to rotate to generate electricity, and the water flows through the power generation component eventually flows to the water storage tank 6 for collection and storage, and the rainwater and sewage collected and stored in the water storage tank 6 can be used for secondary utilization in engineering projects without requirements for water quality.

[0019] The power generation component includes an impeller 41, a coupling 42 and a generator 43. The cross-sectional shape of the power generation pipe 4 is matched with the shape of the water pipe 2. The middle section of the power generation pipe 4 protrudes outward from the pipe wall to set a placement cavity. The power generation component is arranged in the placement cavity, and the generator 43 is fixed in the placement cavity. The impeller 41 is rotatably installed in the placement cavity. The rotating shaft of the impeller 41 is connected to the input shaft of the generator 43 through the coupling 42. The impeller 41 rotates under the flushing of the water flow, and transmits mechanical energy to the generator 43 through the coupling 42 to drive the generator 43 to generate electricity.

[0020] The impeller 41 is tilted, the upper end of the impeller 41 shaft is close to the axis of the energy-generating tube 4, the lower end of the impeller 41 shaft is far away from the axis of the energy-generating tube 4, the upper end of the impeller 41 shaft is connected to the coupling 42, that is, the generator 43 is located above the impeller, the water flow flushes the impeller 41 to drive the impeller 41 to rotate, the impeller 41 is tilted, the lowest point of the rotation plane of the impeller 41 is located in the energy-generating tube 4, and the highest point is located in the placement cavity, a small amount of water enters the placement cavity under the rotation and swing of the impeller 41, but it will flow back into the energy-generating tube 4, and will not affect the normal operation of the generator 43.

[0021] The blade surfaces of the impeller 41 are all inclined. When the impeller 41 is flushed by water, the impeller 41 as a whole rotates toward the side where the blade surfaces are inclined upward, as shown in the accompanying drawings of the specification. Figure 2 As shown, when the impeller 41 is flushed by water, the impeller 41 rotates clockwise when viewed from a top view.

[0022] The water inlet assembly 1 includes a filter plate 11 and a water inlet bucket 12. The water inlet bucket 12 is fixedly arranged at the lowest point on the top of the construction building. The filter plate 11 is movably mounted on the water inlet of the water inlet bucket 12. The filter plate 11 is a mesh plate, and the plate shape is set to be circular corrugated. The crest is the highest at the center of the circle and decreases gradually outward. The filter plate 11 is used to filter and intercept garbage and impurities to avoid blockage of the drainage system. Impurities move to the filter plate 11 with the water flow, and large impurities are deposited at the troughs of the filter plate 11 under the action of gravity. Because the filter plate 11 is a multi-layer circular corrugated mesh plate as a whole, and the central crest is the highest point, the filter plate 11 is not easily blocked by impurities and will not affect the water flow.

[0023] A cone bucket 31 and a plurality of guide plates 32 are arranged in the body of the guide pipe 3. The tip of the cone bucket 31 is provided with a water hole pointing to the outflow direction of the water flow. The plurality of guide plates 32 are fixedly arranged at equal intervals on the water-facing surface of the cone bucket 31. The plurality of guide plates 32 are all arranged in a spiral line attached to the upper edge of the water-facing surface. The water flows into the guide pipe 3 and is guided by the guide plates 32 to be concentrated into a concentrated water column to flush the impeller 41. The plurality of guide plates 32 are all arranged in a spiral shape, which can effectively gather the water flow and speed up the flow rate of the water flow, enhance the impact force on the impeller 41, and promote the rapid rotation of the impeller 41 to generate electricity.

[0024] The building energy-saving drainage system also includes a power storage component, and the battery of the power storage component is electrically connected to the generator 43 through a circuit. The electric energy generated by the rotation of the generator 43 is stored in the battery through the circuit.

[0025] Working principle: The water pipe 2 of the system selects the corresponding pipe type according to the specific installation and layout conditions. The outer wall shape of the diversion pipe 3, the outer wall shape of the power generation pipe 4, the pipe type of the connecting pipe 7 and the interface shape between each pipe fitting are all set according to the pipe type of the water pipe 2.

[0026] The water inlet component 1 of the system can be arranged at the lowest rainwater collection point on the top floor of the building under construction to directly receive rainwater, so as to introduce natural rainfall into the system, or it can be arranged on each floor slab of a multi-story building under construction to collect and introduce sewage generated after flushing during the construction process.

[0027] Water flows into the system from the water inlet component 1, the filter plate 11 intercepts and filters the debris, the water flows in the guide pipe 3 and is concentrated on the impeller 41, thereby driving the impeller 41 to rotate, and the impeller 41 transmits the mechanical energy to the generator 43 through the coupling 42, the generator 43 converts the mechanical energy into electrical energy, and stores the electrical energy in the storage component through the circuit, the water flows through the various pipes of the system and is collected in the water storage tank, which can be supplied for recycling without requiring water quality, thereby reducing the use of high-standard domestic water and achieving the purpose of energy saving. At the same time, the generated electricity can be used to supplement the construction electricity, the storage component is an independent component and can be replaced, and the fully charged storage component can be transferred according to the specific construction needs, reducing the connection of wires and facilitating the construction.

[0028] In addition, the system can also be used in various built buildings to collect and reuse rainwater. If the power generation capacity needs to be improved, multiple groups of diversion pipes 3 and power generation pipes 4 can be set on a single water pipe 2. The electric energy stored in the storage component can be used according to the specific application situation. For example, in a residential community, rainwater collection can be used for cleaning public areas and watering greenery. The stored electric energy can be used to power greening watering equipment and emergency lighting, etc. The amount of power generated by rainwater is limited and can be used to power low-power equipment with low electricity demand.

[0029] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
