[0026] like Figures 1 to 7 As shown, the present invention provides a low-energy consumption assembled building, comprising a plurality of prefabricated house bodies spliced ​​end to end, each prefabricated house body comprising: The prefabricated shell 1 has a water inlet channel 11 on its top; specifically, the top of the prefabricated shell 1 receives rainwater falling from nature, and the rainwater flows into the prefabricated shell 1 from the water inlet channel 11, and the prefabricated shell 1 is conducive to recycling rainwater resources in nature; A rainwater purification layer 4 is horizontally arranged in the prefabricated shell 1. The rainwater purification layer 4 purifies rainwater from top to bottom. The top of the rainwater purification layer 4 is connected to the water outlet end of the water inlet channel 11. Specifically, the rainwater purification layer 4 can be an activated carbon layer, or can be composed of a shell layer, a coarse sand layer, a carbon filter layer and a gravel layer. Different rainwater purification layers 4 purify rainwater to different degrees. The cavity between the top of the rainwater purification layer 4 and the top of the prefabricated shell 1 forms a temporary storage pool for temporarily storing rainwater. Rainwater flows into the temporary storage pool from the water inlet channel 11, and then passes through the rainwater purification layer 4 from top to bottom. The rainwater is purified to obtain clean water resources. A prefabricated body 2 is detachably arranged on the lower end of the prefabricated shell 1. A drainage hole communicating with the bottom of the rainwater purification layer 4 is opened on the top of the prefabricated body 2, and a drainage branch pipe 5 is arranged on the drainage hole. Specifically, the prefabricated body 2 can be detachably connected with the prefabricated shell 1 through a second enclosure 7 arranged on the top, a slot recessed at the bottom of the prefabricated shell 1, and screw holes, bolts, and nuts. After the purified water permeates from the rainwater purification layer 4, it enters the cavity between the prefabricated body 2 and the bottom of the rainwater purification layer 4, and then flows through the drainage hole and enters the drainage branch pipe 5 for use. Among them, a drainage main pipe 6 is penetrated along the splicing direction of multiple prefabricated bodies 2, and the drainage main pipe 6 is connected with the drainage branch pipes 5 on the multiple prefabricated bodies 2, and a valve is provided on the water outlet end of the drainage main pipe 6; specifically, the drainage branch pipes 5 in the multiple prefabricated bodies 2 are respectively connected with the drainage main pipe 6 through a three-way pipe, so that the purified water in the multiple prefabricated bodies 2 can be collected together for easy use. One end of the drainage main pipe 6 is closed, and the other end is connected to the domestic water pipe set in the prefabricated house body, and a valve is provided. When the valve is opened, water can be discharged from the drainage main pipe 6, so that the purified water can be used in life scenes such as flushing toilets, watering flowers, and washing floors.

[0027] In the above technical scheme, the prefabricated shell 1 is detachably installed on the prefabricated main body 2 to form a prefabricated house body, and multiple prefabricated house bodies are spliced ​​to form an assembled building. When rain falls in nature, the rainwater enters the prefabricated shell 1 through the water inlet channel 11 and is collected in the cavity between the top of the prefabricated shell 1 and the rainwater purification layer 4. Then the rainwater slowly passes through the rainwater purification layer 4 from top to bottom, and forms clean water under the purification of the rainwater purification layer 4. The purified water flows into the drainage hole and enters the drainage branch pipe 5 from the drainage hole. The water in the drainage branch pipes 5 in multiple prefabricated main bodies 2 is collected in the drainage main pipe 6. By opening the valve on the drainage main pipe 6, the purified water can be used in life scenes such as flushing toilets, watering flowers, and washing floors. Among them, the arrangement of the water inlet channel 11, the rainwater purification layer 4, the drainage hole, and the drainage branch pipe 5 enables the assembled building to effectively utilize rainwater resources in nature, which has the beneficial effects of saving water and reducing energy consumption.

[0028] In another technology, the top cover of the prefabricated shell 1 is provided with an impurity filter 3; specifically, the impurity filter 3 is used to filter the coarse impurities falling from the sky, reduce the possibility of the coarse impurities blocking the water inlet channel 11, and reduce the coarse impurities entering the prefabricated shell 1 and accumulating on the rainwater purification layer 4, thereby reducing the impact on the purification efficiency of the rainwater purification layer 4; Also included is a purification layer cleaning structure, which includes: The rotation driving part 12 is provided with an output shaft pointing vertically downward; specifically, the rotation driving part 12 is used to drive the fixing ring 18 and the connecting plate 19 described below to rotate. The rotation driving part 12 may include the collar 13, the rotating rod 14, and the impeller 15 described below, and may also be a waterproof rotating motor. When the rotation driving part 12 is started, the output shaft of the rotation driving part 12 rotates, which can drive the fixing ring 18 and the connecting plate 19 described below to rotate; The fixing ring 18 is fixedly sleeved on the output shaft of the rotating driving part 12; specifically, the fixing ring 18 can be fixedly sleeved on the output shaft of the rotating driving part 12 near the lower end by welding or screwing, and the output shaft of the rotating driving part 12 rotates to drive the fixing ring 18 to rotate, thereby driving the following connecting plate 19 and bristles 20 to rotate; A plurality of connecting plates 19 are provided on the fixing ring 18 at intervals along the circumference thereof, bristles 20 are provided at the bottom of the connecting plates 19, and the lower ends of the bristles 20 are provided in contact with the top of the rainwater purification layer 4; specifically, the connecting plates 19 can be fixed on the fixing ring 18 by welding or screwing, and the connecting plates 19 can be L-shaped, with the top end thereof being provided at the bottom of the fixing ring 18, so as to facilitate the installation of the waterproof generator 16 described below, and the connecting plates 19 are rotated under the driving force of the rotation of the fixing ring 18, thereby causing the bristles 20 located at the bottom of the connecting plates 19 to rotate, and the bristles 20 are in contact with the top of the rainwater purification layer 4 during the rotation. The top of the rainwater purification layer 4 is in contact with the bristles 20, so that the bristles 20 can clean the rainwater purification layer 4, which is beneficial to maintaining the purification efficiency of the rainwater purification layer 4, wherein the rainwater purification layer 4 can be cylindrical with the central axis of the fixing ring 18, and the rainwater purification layer 4 can be horizontally arranged on the prefabricated shell 1 through a frame plate arranged on its periphery, and the radius of the circular cross-section of the rainwater purification layer 4 is less than or equal to the length of the bristles 20 on the connecting plate 19, so that the area cleaned by the bristles 20 is larger than the cross-sectional area of ​​the rainwater purification layer 4, so that the bristles 20 can clean the fine impurities deposited on the rainwater purification layer 4 in multiple directions.

[0029] In the above technical solution, the impurity filter 3 is used to filter rainwater, and the coarse impurities falling from the sky are retained on the impurity filter 3, thereby reducing the possibility of coarse impurities blocking the water inlet channel 11, and making the impurities entering the prefabricated shell 1 less, reducing the accumulation of impurities on the rainwater purification layer 4. The influence of the purification efficiency of the rainwater purification layer 4 on the purification efficiency of the rainwater purification layer 4, but there are still some impurities with a particle size smaller than the mesh diameter of the impurity filter 3 that pass through the impurity filter 3 into the prefabricated shell 1 and are deposited on the surface of the rainwater purification layer 4, and the rotating drive unit 12 is started. The output shaft of the rotating drive unit 12 rotates, driving the fixing ring 18 to rotate, and then driving the multiple connecting plates 19 to rotate, so that the position The bristles 20 on the connecting plate 19 rotate and generate friction with the surface of the rainwater purification layer 4. The force generated by the friction of the bristles 20 can clean up the deposited fine impurities, which is beneficial to maintaining the purification efficiency of the rainwater purification layer 4. The rainwater purification layer 4 is cylindrical with the same central axis as the fixing ring 18. The rainwater purification layer 4 can be horizontally arranged on the prefabricated shell 1 through a frame plate arranged on its periphery. The radius of the circular cross-section of the rainwater purification layer 4 is less than or equal to the length of the bristles 20 on the connecting plate 19, so that the area cleaned by the bristles 20 is larger than the cross-sectional area of ​​the rainwater purification layer 4, so that the bristles 20 can clean up the fine impurities deposited on the rainwater purification layer 4 in multiple directions.

[0030] In another technology, the top of the prefabricated shell 1 is recessed with a plurality of low-lying water tanks 21 arranged around the water inlet channel 11, and the low-lying water tanks 21 are inclined from top to bottom in the direction toward the water inlet channel 11, and one end of the low-lying water tank 21 is provided with an eccentric water outlet 22 connected with the water inlet channel 11; specifically, the low-lying water tanks 21 help to collect rainwater received on the top of the prefabricated shell 1, thereby increasing the flow rate of rainwater when it flows into the water inlet channel 11, and the setting of the low-lying water tanks 21 inclined from top to bottom in the direction toward the water inlet channel 11 helps to increase the flow rate of rainwater when it flows into the water inlet channel 11, so that the energy of rainwater entering the water inlet channel 11 is greater, and the setting of the eccentric water outlet 22 enables rainwater to eccentrically impact the impeller 15 described below when it flows out of the low-lying water tanks 21, so as to drive the impeller 15 to rotate; The rotation driving unit 12 includes: A collar 13, which is coaxially rotatably connected to the water inlet channel 11; specifically, the outer wall of the collar 13 can be coaxially rotatably connected to the water inlet channel 11 through a bearing, and the collar 13 provides lateral support for the impeller 15 and the rotating rod 14 described below, preventing the rotating rod 14 from tilting and affecting its own rotation; A rotating rod 14 is suspended and penetrated on the sleeve ring 13, and the fixing ring 18 is fixedly sleeved on the lower end of the rotating rod 14; specifically, the rotating rod 14 is coaxially suspended and penetrated on the sleeve ring 13 through the impeller 15 described below, and the rotating rod 14 forms the output shaft of the rotating driving part 12, which is used to drive the fixing ring 18 to rotate; A plurality of impellers 15 are provided on the rotating rod 14 at intervals along its circumference, and one side of the impeller 15 is fixedly connected to the inner wall of the collar 13; specifically, the impeller 15 can be fixedly provided on the rotating rod 14 by welding or screwing, and the impeller 15 and the inner wall of the collar 13 can be fixedly connected by welding, and rainwater flows out from the low-lying gutter 21 through the eccentric water outlet 22, eccentrically impacting the impeller 15, and the energy of the eccentric impact of the rainwater drives the impeller 15 to rotate, thereby driving the rotating rod 14 to rotate, thereby driving the bristles 20 to rotate, and achieving the beneficial effect of using rainwater resources to drive the bristles 20 to clean the rainwater purification layer 4.

[0031] Among them, the extension line from the low-lying water trough 21 to the eccentric water outlet 22 does not intersect with the central axis of the rotating rod 14; specifically, the setting of the extension line direction from the low-lying water trough 21 to the eccentric water outlet 22 helps to achieve the beneficial effect of eccentrically impacting the impeller 15 when rainwater flows out from the eccentric water outlet 22.

[0032] In the above technical solution, rainwater continuously falls from the sky, and the top of the prefabricated shell 1 receives the rainwater and collects it in the low-lying water tank 21. The water in the low-lying water tank 21 flows from top to bottom in the direction toward the water inlet channel 11, and the rainwater eccentrically impacts the impeller 15 located in the water inlet channel 11 in a unidirectional manner through the eccentric water outlet 22. The energy of the eccentric impact of the rainwater drives the impeller 15 to rotate, and the rotation of the impeller 15 drives the fixed ring 18 to rotate, and then drives the connecting plate 19 and the bristles 20 to rotate. The setting of the eccentric impact of the rainwater on the impeller 15 effectively utilizes the flow of rainwater resources and the energy of falling to drive the bristles 20 for cleaning without the need for an external motor or other external force.

[0033] In another technique, a power storage device is provided in the prefabricated body 2; specifically, the power storage device may be a battery; It also includes a waterproof generator 16, which is arranged on the top of the rainwater purification layer 4, and the main shaft of the waterproof generator 16 is coaxially fixedly connected to the bottom of the rotating rod 14, and the waterproof generator 16 is connected to the power storage device by wires; specifically, the waterproof shell of the waterproof generator 16 is fixedly arranged on the top of the rainwater purification layer 4, and rainwater drives the rotating rod 14 to rotate, which can drive the coaxial main shaft of the waterproof generator 16 to rotate, thereby realizing power generation. The setting of the waterproof generator 16 enables the energy of the flow and falling of rainwater resources to be effectively recovered, and further effectively utilizes rainwater resources. Among them, the main shaft of the waterproof generator 16 can also be connected to the bottom of the rotating rod 14 through a speed increaser. The function of the speed increaser is the same as its function in the wind power generation process, which can transmit the low-speed power generated by the rotating rod 14 under the action of rainwater to the waterproof generator 16, and increase its rotation speed to the high rotation speed required by the waterproof generator 16, thereby ensuring that the waterproof generator 16 can generate electricity efficiently.

[0034] In another technology, the top end of the rotating rod 14 passes through the water inlet channel 11 and the impurity filter 3 in sequence, and a plurality of wind-bearing blades 17 are provided on the top end of the rotating rod 14 along its circumference; specifically, the wind-bearing blades 17 are used to absorb the energy of the wind in nature. When the wind in nature reaches a certain level, the wind pushes the wind-bearing blades 17 to rotate, and the wind-bearing blades 17 rotate, thereby driving the rotating rod 14 to rotate, which can not only achieve the beneficial effect of using wind power to drive the bristles 20 to clean the rainwater purification layer 4, but also use wind power to generate electricity, effectively recover the energy of the wind, and make full use of wind resources.

[0035] In another technology, the impeller 15 is a bucket-type impeller 15; specifically, the bucket-type impeller 15 is composed of a series of double-bowl-shaped buckets. The bucket-type impeller 15 can rotate even in a small water flow, and can also drive the waterproof generator 16 to generate electricity, and has a better energy recovery effect. The setting of the bucket-type impeller 15 enables the impeller 15 to be impacted and rotated when the rainwater flow is small, and can efficiently utilize rainwater resources.

Specifically, the material of the noise reduction layer 8 can be a waterproof and sound-absorbing material such as a rubber plate, a foamed silicone plate, and a polyurethane foam plastic. The noise reduction layer 8 is laid on the top of the prefabricated body 2 to receive the discharged water after purification from the rainwater purification layer 4 and reduce the noise generated by water drops falling on the top of the prefabricated body 2. The cavity between the noise reduction layer 8 and the bottom of the rainwater purification layer 4 forms a water storage tank to collect the purified water. The collected water enters the drainage hole from the water through hole located on the low-lying part, and then flows into the drainage branch pipe 5. The side wall of the noise reduction layer 8 abuts against the inner wall of the prefabricated shell 1, and a sealing ring is provided at the abutment to prevent water from leaking out of the water storage tank from the abutment. The low-lying part makes it easier for the water collected in the water storage tank to flow into the drainage hole, so as to conveniently utilize the water collected in the water storage tank.

The coarse sand layer is located below the shell layer, and mainly through its larger particle gaps, it effectively intercepts larger suspended matter and impurities, thereby filtering particulate impurities in rainwater. The carbon filter layer is made of activated carbon, which has a strong adsorption capacity and can remove organic pollutants, heavy metal ions and other harmful substances in rainwater, and can significantly improve water quality. The gravel layer is located below the carbon filter layer, and the larger particle gaps in the gravel layer allow water to pass through, and at the same time can further intercept larger particles of suspended matter, which is used to further purify water quality and promote drainage; the rainwater purification layer 4 composed of the shell layer, the coarse sand layer, the carbon filter layer and the gravel layer from top to bottom can effectively remove impurities and pollutants in rainwater and provide clean water resources for use.

The slots provided at the lower ends of the second enclosure 7 and the first enclosure 9 make it easy to assemble the prefabricated shell 1 on the prefabricated main body 2 to form the prefabricated house body.

[0039] In another technology, the splicing structure of two adjacent prefabricated shells 1 and the splicing structure of two adjacent prefabricated main bodies 2 are of the same structure, and the splicing structure includes a pair of splicing plates 23, and the pair of splicing plates 23 are respectively protruded on the two adjacent prefabricated main bodies 2 and abutted against each other. The splicing plates 23 are located on the outer wall of the prefabricated main body 2 perpendicular to the splicing direction of multiple prefabricated house bodies, and the pair of splicing plates 23 are fixed by screw holes, bolts, and nuts; specifically, a pair of splicing splices two adjacent prefabricated main bodies 2 or prefabricated shells 1, and is fixed by screw holes, bolts, and nuts.
