Description

Technical Field

[0001] This invention relates to the technical field of prefabricated building construction, and in particular to a prefabricated green building. Background Technology

[0002] Currently, prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to the construction site, and assembled and installed on-site using reliable connection methods.

[0003] Relevant technology can be found in Chinese Utility Model Patent No. CN214738723U, which discloses a green prefabricated building, including a base plate, several wall panels fixedly connected to the base plate, and a transition keel. The wall panels and the base plate enclose an activity space. The prefabricated building also includes a ring beam connected to the wall panels and a green roof that shelters the top of the activity space. The ring beam is arranged around the activity space along the line connecting the wall panels. The green roof includes several prefabricated panels spliced ​​together in sequence. The side of each prefabricated panel facing away from the activity space has a planting trough for planting vegetation. A sealing component connects the side of the prefabricated panel closest to the activity space to the wall panel. The transition keel is a rectangular steel pipe, and a first transition bolt for connecting the transition keel and the wall panel and a second transition bolt for connecting the transition keel and the base plate are threaded through the transition keel.

[0004] However, the precast slabs do not allow for the collection of rainwater above the soil layer in the planting trough. When it is necessary to irrigate the plants in the planting trough, water usually needs to be drawn from elsewhere multiple times, which can easily lead to a waste of water resources. Summary of the Invention

[0005] This application provides a prefabricated green building that facilitates the collection of rainwater above the soil layer in the planting trough, thereby facilitating the irrigation of plants in the planting trough and reducing water waste.

[0006] This application provides a prefabricated green building, which adopts the following technical solution:

[0007] A prefabricated green building includes a base slab, several wall panels, a green roof, and a ring beam. The green roof comprises several prefabricated slabs assembled sequentially, each slab having a planting trough. A connecting device is provided between each wall panel and the base slab. A collection box is detachably connected to each prefabricated slab. The side of the collection box near the planting trough is connected to multiple water inlet pipes. The top wall of the planting trough has multiple grooves for placing the water inlet pipes. The end of each water inlet pipe away from the collection box is connected to the inner cavity of the planting trough. A water pump is installed on the top of the planting box. The inlet of the water pump is connected to a water pump pipe. The end of the water pump away from the water pump is connected to the inner cavity of the collection box. The outlet of the water pump is connected to a water supply pipe. Multiple nozzles are connected to the water supply pipe, and the nozzles are positioned facing the planting trough.

[0008] By adopting the above technical solution, on rainy days, when there is a lot of rainwater above the soil layer in the planting trough, the rainwater enters the collection box through the inlet pipe, thus facilitating the collection of rainwater above the soil layer in the planting trough. When it is sunny and the plants in the planting trough need to be watered, the water pump is started. At this time, the water in the collection box passes through the water pump and the water supply pipe in sequence, and is then sprayed onto the plants in the planting trough by the nozzle, thus facilitating the irrigation of the plants in the planting trough and reducing the waste of water resources.

[0009] Preferably, a rotating shaft is rotatably connected inside the collection box, and a drive mechanism for driving the rotating shaft to rotate is provided inside the collection box; a speed increaser is installed on the top of the collection box, one end of the rotating shaft is connected to the input shaft of the speed increaser, and the output shaft of the speed increaser is connected to a generator, which can supply power to the water pump.

[0010] By adopting the above technical solution, when rainwater flows into the collection box through the inlet pipe, the shaft rotates under the action of the drive mechanism. After passing through the speed increaser and the generator, it can generate electricity, which facilitates powering the water pump and thus saves energy.

[0011] Preferably, the driving mechanism includes a driving plate that slides vertically along the inner wall of the collection box and a plurality of first springs fixed to the bottom of the driving plate. The end of the first spring away from the driving plate is fixed to the bottom wall of the collection box. The driving plate has a through hole, and the outer wall of the rotating shaft has a plurality of spiral blocks arranged in sequence along its circumference. The inner wall of the through hole has a plurality of spiral grooves arranged in sequence along its circumference. The plurality of spiral blocks and the plurality of spiral grooves correspond to each other one by one.

[0012] By adopting the above technical solution, in rainy weather, the drive plate moves downward under the gravity of the rainwater, and then the drive plate can drive the rotating shaft to rotate under the action of the spiral block and spiral groove; the set drive mechanism facilitates the rotation of the rotating shaft. The set first spring facilitates the reset of the drive plate.

[0013] Preferably, a lead screw is rotatably connected inside the collection box, and a handwheel is installed on the top of the lead screw, which penetrates the top wall of the collection box; a push plate is threaded onto the lead screw, the push plate abuts against the top of the drive plate, and the push plate slides vertically to the inner wall of the collection box.

[0014] By adopting the above technical solution, when the water pump needs more power, the screw is driven to rotate by the handwheel. The rotation of the screw drives the push plate to move downward, and the downward movement of the push plate drives the drive plate to move downward, thereby enabling the generator to generate electricity. The screw and push plate are designed to facilitate further generation of electricity by the generator.

[0015] Preferably, the connecting device includes an insert plate fixed to the bottom of the wall panel, a connecting plate prefabricated on the base plate, and a slot for inserting the insert plate into the top of the connecting plate; a limiting mechanism for limiting the position of the insert plate is installed inside the connecting plate.

[0016] By adopting the above technical solution, when it is necessary to connect the wall panel and the base plate, the wall panel is first moved to insert the insert plate into the slot, and then the insert plate is limited by the limiting mechanism; the connection device is set to facilitate the connection between the wall panel and the base plate.

[0017] Preferably, the limiting mechanism includes a baffle that slides vertically to the slot and a second spring fixed to the bottom of the baffle. The end of the second spring away from the baffle is fixed to the bottom of the slot. A horizontal groove is formed on one side wall of the slot, and a limiting block is slidably connected in the horizontal groove. A limiting hole for the limiting block to be inserted is formed on the insert plate. A third spring is fixed to the end of the limiting block away from the baffle. The end of the third spring away from the limiting block is fixed to the inner wall of the horizontal groove away from the baffle. The limiting block can abut against one side of the baffle. When the limiting block abuts against the baffle, the third spring is in a compressed state. A strip-shaped hole is formed on the top wall of the horizontal groove. The end of the strip-shaped hole away from the horizontal groove extends vertically upward through the top wall of the base plate. A push block is slidably connected in the strip-shaped hole. The bottom of the push block is fixed to the top of the limiting block. A fixing block is installed on the top of the base plate. A bolt is threadedly connected to the fixing block. One end of the bolt can be threadedly connected to the push block.

[0018] By adopting the above technical solution, when the insert plate is inserted into the slot, the insert plate pushes the baffle downwards. When the insert plate moves to align the limiting block with the limiting groove, the limiting block engages with the limiting groove under the action of the third spring, thereby limiting the insertion plate. The limiting mechanism facilitates the limiting of the insert plate. When it is necessary to separate the insert plate from the slot, the limiting block is first separated from the limiting groove by the push block, then the push block is locked by bolts, and then the insert plate can be separated from the slot by moving the wall panel. In summary, the connecting device facilitates the assembly and disassembly of the wall panel.

[0019] Preferably, the connecting plate has a movable groove and a vertical groove, the movable groove being connected to both the slot and the vertical groove; a sealing plate is slidably connected in the vertical groove, and a sealing groove for the sealing plate to be inserted is provided at the bottom of the wall panel; a sliding groove is provided on one side of the vertical groove, a slider is slidably connected in the sliding groove, a fourth spring is fixedly connected to the top of the slider, the end of the fourth spring away from the slider is fixedly connected to the inner side of the top of the sliding groove, and the slider is fixedly connected to one side of the sealing plate; a driving component for driving the sealing plate to be inserted into the sealing groove is installed in the movable groove.

[0020] By adopting the above technical solution, when the insert plate is inserted into the slot, the baffle moves downward under the action of the insert plate. At this time, the baffle drives the sealing plate to insert into the sealing groove under the action of the driving component, thereby achieving a certain degree of sealing at the connection between the wall panel and the base plate.

[0021] Preferably, the driving component includes a horizontal shaft rotatably connected to the inner wall of the movable groove and a torsion spring sleeved on the horizontal shaft; a rotating plate is fixedly sleeved on the horizontal shaft, one end of the torsion spring is fixedly connected to the rotating plate, and the other end is fixedly connected to the inner wall of the movable groove; the two ends of the rotating plate abut against the bottom of the baffle and the sealing plate, respectively.

[0022] By adopting the above technical solution, when the insert plate is inserted into the slot, the baffle moves downward under the action of the insert plate. The movement of the baffle pushes the rotating plate to rotate, and the rotation of the rotating plate can drive the sealing plate to be inserted into the sealing groove. The driving component is set to facilitate the insertion of the sealing plate into the sealing groove.

[0023] In summary, this application has the following beneficial effects:

[0024] 1. On rainy days, when there is a lot of rainwater above the soil layer in the planting trough, the rainwater enters the collection box through the inlet pipe, making it easy to collect the rainwater above the soil layer in the planting trough. When it is sunny and the plants in the planting trough need to be watered, the water pump is started. At this time, the water in the collection box passes through the water pump and the water supply pipe in sequence, and then is sprayed onto the plants in the planting trough by the nozzle, which makes it easy to irrigate the plants in the planting trough and thus reduces the waste of water resources.

[0025] 2. When rainwater flows into the collection box through the inlet pipe, the shaft rotates under the action of the drive mechanism. After passing through the speed increaser and the generator, it can generate electricity, which can then power the water pump and save energy.

[0026] 3. When the insert plate is inserted into the slot, it pushes the baffle downwards. Once the insert plate moves to align the limiting block with the limiting groove, the limiting block engages with the limiting groove under the action of the third spring, thus limiting the insertion plate. This limiting mechanism facilitates the limiting of the insert plate. When it is necessary to separate the insert plate from the slot, first use the push block to separate the limiting block from the limiting groove, then lock the push block with bolts, and finally move the wall panel to separate the insert plate from the slot. In summary, the designed connecting device facilitates the assembly and disassembly of the wall panel. Attached Figure Description

[0034] This invention discloses a prefabricated green building, such as Figure 1 As shown, it includes a base plate 1, several wall panels 2, a green roof and a ring beam. The green roof includes several precast slabs 3 spliced ​​together in sequence. A planting trough 31 is opened on the top of the precast slabs 3. A connecting device 7 is provided between each wall panel 2 and the base plate 1.

[0035] like Figure 2 and Figure 3As shown, a placement groove 32 is provided on the top of the precast slab 3, and a collection box 4 is inserted into the placement groove 32. The collection box 4 is bolted to the precast slab 3. Multiple water inlet pipes 41 are sequentially connected to the side of the collection box 4 near the planting trough 31 along the length of the precast slab 3. Multiple grooves 33 for placing the water inlet pipes 41 are provided on the top wall of the planting trough 31. The end of the water inlet pipe 41 away from the collection box 4 is connected to the inner cavity of the planting trough 31 and is equipped with a filter screen. A water pump 4 is installed on the top of the planting box. 2. The inlet of the water pump 42 is connected to the water pump pipe 43. The end of the water pump pipe 43 away from the water pump 42 is connected to the inner cavity of the collection box 4. The outlet of the water pump 42 is connected to the water supply pipe 44 through a pipe. The two ends of the water supply pipe 44 are closed. The water supply pipe 44 is installed on the top of the collection box 4 through a pipe bracket. The water supply pipe 44 is set along the length of the precast slab 3. Multiple nozzles 45 are connected to the water supply pipe 44 in sequence along its axial direction. The nozzles 45 are set towards the planting trough 31.

[0036] like Figure 2 and Figure 3 As shown, a rotating shaft 46 is vertically rotatably connected inside the collection tank 4 via bearings. A drive mechanism 5 is installed inside the collection tank 4 to drive the rotating shaft 46. A speed increaser 47, a rectifier 481, a battery 482, and an inverter 483 are installed on the top of the collection tank 4. One end of the rotating shaft 46 is connected to the input shaft of the speed increaser 47, and the output shaft of the speed increaser 47 is connected to a generator 49. The electricity generated by the generator 49 is rectified by the rectifier 481 and then charges the battery 482. The battery 482 then supplies power to the water pump 42 through the inverter 483. For ease of understanding, the rectifier 481, battery 482, and inverter 483 are normally placed inside an electrical box. When rainwater flows into the collection tank 4 through the inlet pipe 41, the rotating shaft 46 rotates under the action of the drive mechanism 5. After passing through the speed increaser 47 and the generator 49, it generates electricity, thus supplying power to the water pump 42 and saving energy.

[0037] like Figure 2 and Figure 3As shown, the drive mechanism 5 includes a drive plate 51 that slides vertically along the inner wall of the collection box 4 and multiple first springs 52 that are vertically fixed to the bottom of the drive plate 51. A sealing ring 513 is sleeved on the circumference of the drive plate 51, and the end of the first spring 52 away from the drive plate 51 is fixed to the bottom wall of the collection box 4. A through hole 511 is provided on the drive plate 51, and multiple spiral blocks 53 are arranged sequentially along the circumference of the outer wall of the rotating shaft 46. Multiple spiral grooves 512 are arranged sequentially along the circumference of the inner wall of the through hole 511, and the multiple spiral blocks 53 and multiple spiral grooves 512 are matched one-to-one. In rainy weather, the drive plate 51 moves downward under the gravity of the rainwater, and then the drive plate 51 can drive the rotating shaft 46 to rotate under the action of the spiral blocks 53 and spiral grooves 512. The drive mechanism 5 is provided to facilitate the rotation of the rotating shaft 46. The first springs 52 are provided to facilitate the reset of the drive plate 51.

[0038] like Figure 2 and Figure 3 As shown, a lead screw 6 is vertically rotatably connected to the collection box 4 via a bearing. The top of the lead screw 6 penetrates the top wall of the collection box 4 and is fitted with a handwheel 61. A push plate 62 is threaded onto the lead screw 6 and abuts against the top of the drive plate 51. A guide rod 63 is vertically fixed to the inner wall of the collection box 4 and penetrates the drive plate. The push plate 62 slides vertically and is connected to the guide rod 63. Furthermore, both the guide rod 63 and the lead screw 6 penetrate the drive plate 51, and the drive plate 51 is sealed to the guide rod 63 and the lead screw 6 via sealing rings. An exhaust pipe 64 is threaded onto the top of the collection box 4. One end of the exhaust pipe 64 extends vertically upward through the top of the collection box 4, and the other end extends vertically downward through the drive plate 51. The drive plate 51 is sealed to the outer wall of the exhaust pipe 64 via sealing rings. When the water pump 42 needs more power, the handwheel 61 drives the lead screw 6 to rotate. The rotation of the lead screw 6 drives the push plate 62 to move downward. The downward movement of the push plate 62 drives the drive plate 51 to move downward, thereby enabling the generator 49 to generate electricity. The lead screw 6 and push plate 62 are designed to facilitate further power generation by the generator 49.

[0039] like Figure 4 and Figure 5 As shown, the connecting device 7 includes an insert plate 71 vertically fixed to the bottom of the wall panel 2, and a connecting plate 72 prefabricated on the base plate 1. The top of the connecting plate 72 has a slot 721 for inserting the insert plate 71. A limiting mechanism 8 for limiting the position of the insert plate 71 is installed inside the connecting plate 72. When it is necessary to connect the wall panel 2 and the base plate 1, the wall panel 2 is moved first to insert the insert plate 71 into the slot 721, and then the limiting mechanism 8 limits the position of the insert plate 71. The connecting device 7 facilitates the connection between the wall panel 2 and the base plate 1.

[0040] like Figure 5As shown, the limiting mechanism 8 includes a baffle 81 that slides vertically to the slot 721 and two second springs 82 that are vertically fixed to the bottom of the baffle 81. The end of each second spring 82 away from the baffle 81 is fixed to the bottom of the slot 721. A horizontal groove 722 is formed on one side wall of the slot 721. A limiting block 83 slides horizontally within the horizontal groove 722. A limiting hole 711 is formed on the insert plate 71 for the insertion of the limiting block 83. A third spring 84 is horizontally fixed to the end of the limiting block 83 away from the baffle 81. The end of the third spring 84 away from the limiting block 83 is fixed to the inner wall of the horizontal groove 722 away from the baffle 81. 83 can abut against one side of the baffle 81. When the limiting block 83 abuts against the baffle 81, the third spring 84 is in a compressed state. The top wall of the horizontal groove 722 is provided with a strip hole 723. The end of the strip hole 723 away from the horizontal groove 722 extends vertically upward through the top wall of the base plate 1. A push block 85 is slidably connected in the strip hole 723 along the length direction of the limiting block 83. The bottom of the push block 85 is fixed to the top of the limiting block 83. A fixing block 86 is installed on the top of the base plate 1. A bolt 87 is threadedly connected to the fixing block 86. One end of the bolt 87 can be threadedly connected to the push block 85. A protective cover 88 for protecting the bolt 87 is hinged on the base plate 1. When the insert plate 71 is inserted into the slot 721, the insert plate 71 pushes the baffle 81 downward. When the insert plate 71 moves to align the limiting block 83 with the limiting groove, the limiting block 83, under the action of the third spring 84, engages with the limiting groove, thereby limiting the insertion plate 71. The limiting mechanism 8 facilitates the limiting of the insert plate 71. When it is necessary to separate the insert plate 71 from the slot 721, the limiting block 83 is first separated from the limiting groove by the push block 85, and then the push block 85 is locked by the bolt 87. Subsequently, the insert plate 71 can be separated from the slot 721 by moving the wall panel 2. In summary, the connecting device 7 facilitates the assembly and disassembly of the wall panel 2.

[0041] like Figure 5As shown, the connecting plate 72 has a movable groove 724 and a vertical groove 725. The movable groove 724 is connected to both the slot 721 and the vertical groove 725. A sealing plate 89 is vertically slidably connected in the vertical groove 725. A sealing groove 21 for the sealing plate 89 to be inserted is provided at the bottom of the wall plate 2. A sliding groove 726 is provided on one side of the vertical groove 725. The sliding groove 726 extends vertically and a slider 891 is vertically slidably connected in the sliding groove 726. A fourth spring 892 is vertically fixed to the top of the slider 891. The end of the fourth spring 892 away from the slider 891 is fixed to the inner side of the top of the sliding groove 726. The slider 891 is fixed to one side of the sealing plate 89. A driving component 9 for driving the sealing plate 89 to be inserted into the sealing groove 21 is installed in the movable groove 724. When the insert plate 71 is inserted into the slot 721, the baffle 81 moves downward under the action of the insert plate 71. At this time, the baffle 81 drives the sealing plate 89 to be inserted into the sealing groove 21 under the action of the driving component 9, so as to seal the connection between the wall panel 2 and the base plate 1 to a certain extent.

[0042] like Figure 5 As shown, the driving component 9 includes a horizontal shaft 91 rotatably connected to the inner wall of the movable groove 724 via bearings and a torsion spring 92 sleeved on the horizontal shaft 91; a rotating plate 93 is fixedly mounted on the horizontal shaft 91, one end of the torsion spring 92 is fixedly connected to the rotating plate 93, and the other end is fixedly connected to the inner wall of the movable groove 724; both ends of the rotating plate 93 abut against the bottom of the baffle 81 and the sealing plate 89 respectively, and the end of the rotating plate 93 near the baffle 81 is located between two second springs 82. When the insert plate 71 is inserted into the slot 721, the baffle 81 moves downward under the action of the insert plate 71, and the movement of the baffle 81 pushes the rotating plate 93 to rotate, and the rotation of the rotating plate 93 can drive the sealing plate 89 to be inserted into the sealing groove 21; the driving component 9 is provided to facilitate the insertion of the sealing plate 89 into the sealing groove 21.

[0043] Working principle: On rainy days, when there is a lot of rainwater above the soil layer in the planting trough 31, the rainwater enters the collection box 4 through the inlet pipe 41, thus facilitating the collection of rainwater above the soil layer in the planting trough 31. When it is sunny and the plants in the planting trough 31 need to be watered, the water pump 42 is started. At this time, the water in the collection box 4 passes through the water pump pipe 43, the water pump 42 and the water supply pipe 44 in sequence, and is then sprayed onto the plants in the planting trough 31 by the nozzle 45, thus facilitating the irrigation of the plants in the planting trough 31 and reducing the waste of water resources.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
