Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The invention provides a BIM-based rural garbage sewage recycling system 10 which comprises a sewage treatment station 11 and a greenhouse planting greenhouse 12 as shown in figure 1, wherein the sewage treatment station 11 is connected with the greenhouse planting greenhouse 12 through a pipeline, and a plurality of water planting devices 20 (as shown in figure 2) are arranged in the greenhouse planting greenhouse 12.

Wherein, as shown in fig. 2, each hydroponic planting device 20 includes: a planting rack 30, a cultivating device 40 and a water supply network 50. The planting frame 30 is provided with a plurality of layers 31, the layers 31 are inclined structures, the number of the cultivation devices 40 is multiple, a plurality of cultivation devices 40 are placed on the layers 31 in batches, and each cultivation device 40 is connected with a water supply network 50.

When the device is used, as shown in fig. 1, each rural resident is connected with the sewage treatment station 11 through a pipeline, and the laid pipelines are complicated due to the dispersion among the rural residents, so that a constructor firstly adopts a BIM (building information model) to establish a model information database before laying, the complicated pipelines can be formed with a planned pipeline network, the working efficiency is improved, the laying cost is reduced, and meanwhile, the later-stage maintenance is facilitated. Domestic sewage of rural residents continuously enters the sewage treatment station through a pipeline network, the sewage treatment station forms regenerated water after a series of treatments, and then the regenerated water is conveyed to the plurality of greenhouse planting greenhouses 12 through pipelines to supply water to plants. Specifically, as shown in fig. 2, a plurality of hydroponic planting devices 20 are provided in the greenhouse 12, and the regenerated water enters a water supply network 50 thereof and supplies water to each cultivation device 40.

In contrast to the conventional sewage treatment method, the rural garbage sewage recycling system 10 of the present invention uses the reclaimed water for irrigating crops, rather than discharging the reclaimed water directly into a river. Therefore, the water conservancy can be effectively used for regeneration, so that the purpose of saving water is achieved, and the crops can resist cold and drought weather. Meanwhile, compared with tap water, the reclaimed water after sewage treatment contains more phosphorus elements and nitrogen elements, and is more beneficial to the growth of crops.

Furthermore, conventional hydroponic plants generally use flowing water, which is convenient for adding nutrient solution, for example, a grower only needs to inject nutrient solution at the source, and nutrient solution can flow through each crop along with water flow. Moreover, the roots of the crops consume oxygen in the water continuously, and if the water is kept still, the oxygen concentration near the roots is gradually reduced, thereby affecting the growth of the crops. However, the water culture mode can reduce the utilization rate of water, thereby causing waste of water resources. Therefore, the present invention further improves the cultivation device 40 to increase the utilization rate of water, thereby saving water resources.

Specifically, as shown in fig. 3 and 4, the incubation device 40 includes: the base 100 is provided with a receiving groove 110, the cultivating pot 200 is placed on the receiving groove 110, the water supply assembly 300 is provided with a fertilizing assembly 400, and the cultivating pot 200 is placed on the receiving groove 110.

The pressure piston 320 is slidably disposed in the pressure tank 310, and a compression-resistant elastic member 321 is disposed between the pressure piston 320 and the pressure tank 310. The negative pressure suction pipe 330 is a bent pipe structure, and the negative pressure suction pipe 330 is provided with a suction port 331 and a water outlet 332, and the electromagnetic valve 313 and the suction port 331 are both communicated with the accommodating groove 110.

The auxiliary piston 420 is slidably disposed in the auxiliary fertilization tank 410, and a return elastic member 421 is disposed between the auxiliary piston 420 and the auxiliary fertilization tank 410. The nutrient solution storage tank 430 is fixedly arranged in the base 100, and the nutrient solution storage tank 430 is communicated with the inlet opening 411. Preferably, the one-way valve 413 of the inlet port 411 allows only liquid to flow into the fertilization auxiliary tank 410, and the one-way valve 413 of the outlet port 412 allows only liquid to flow out of the fertilization auxiliary tank 410.

Furthermore, the cultivating device 40 further includes a cooperating assembly 500, and the water supply assembly 300 is drivingly connected to the fertilizing assembly 400 through the cooperating assembly 500.

As shown in fig. 6, the water supply network 50 includes a water inlet pipe 51 and a water outlet pipe 52, wherein the water inlet pipe 51 is provided with a water pump 53, the water inlet pipe 51 is communicated with the water inlet 311 of the pressure tank 310, and the water outlet pipe 52 is communicated with the water outlet 332 of the negative pressure suction pipe 330.

When in use, crops are planted in the cultivating pot 200, and the cultivating pot 200 is placed on the accommodating groove 110. Preferably, as shown in fig. 7, the cultivating pot 200 is provided with a clamping position 201 and a vent 202, the cultivating pot 200 can be stably clamped on the accommodating groove 110 by means of the clamping position 201, and the root system of the crop can extend into the accommodating groove 110 through the vent 202 of the cultivating pot 200. The sewage-treated regeneration water is delivered to each of the cultivation devices 40 through the water inlet pipe 51 of the water supply pipe network 50, then enters the housing recess 110 through the pressure tank 310, is then mixed with the nutrient solution in the housing recess 110 and stands still for a certain period of time, and then flows back to the water outlet pipe 52 through the negative pressure suction pipe 330. Moreover, when the reclaimed water enters the accommodating groove 110, the fertilizer applying assembly 400 injects the nutrient solution into the accommodating groove 110, and the ratio of the nutrient solution to the reclaimed water is fixed. The regenerated water and the nutrient solution are mixed in the receiving groove 110 and left standing for a period of time during which the roots of the crops can draw up the nutrients and moisture in the mixed solution. That is, the water culture method of the present invention is to add fresh water and nutrient solution into the accommodating recess 110 at regular time and discharge "expired water" out of the accommodating recess 110, and the specific operation principle will be described below.

Preferably, as shown in fig. 4, a plurality of accommodating grooves 110 are formed on the base 100, and a water supply assembly 300 and a fertilizer application assembly 400 are disposed in each accommodating groove 110.

The first piston rod 322 can not only guide and limit the sliding of the pressure piston 320, but also prevent the pressure-resistant elastic element 321 from being dislocated when deformed; in a similar way, the auxiliary piston 420 is provided with a second piston rod 422, the reset elastic member 421 is of a spring structure, the second piston rod 422 penetrates through the reset elastic member 421, the effect of the second piston rod 422 is similar to that of the first piston rod 322, the second piston rod 422 not only plays a role of limiting and guiding the auxiliary piston 420, but also can prevent the reset elastic member 421 from being dislocated in the deformation process.

In order to allow the fertilization assembly 400 to be coupled with the water supply assembly 300 so as to supply the nutrient solution into the receiving recess 110 at an appropriate time, the cooperation assembly 500 is provided in the present invention, and the water supply assembly 300 is drivingly connected with the fertilization assembly 400 through the cooperation assembly 500. The cooperating assembly 500 is mainly for allowing the water supply assembly 300 to drive the fertilizing assembly 400, which may have a variety of different structures, and two different embodiments will be exemplified in the present invention.

The first embodiment is as follows:

as shown in fig. 8, the cooperative assembly 500 includes: the driving rack 510 is fixedly connected to the first piston rod 322, the driven gear 520 is rotatably disposed on the second piston rod 422, the auxiliary rack 530 is fixedly disposed on the base 100, the driving rack 510 is engaged with or disengaged from the driven gear 520, and the driven gear 520 is engaged with or disengaged from the auxiliary rack 530. As shown in fig. 9, the auxiliary rack 530 is provided with a slide guide rod 531 and a movable tooth 532, the movable tooth 532 is slidably provided on the slide guide rod 531 via an escape elastic member 533 (shown in fig. 8), and a stopper 534 is provided at a free end of the slide guide rod 531, the stopper 534 preventing the movable tooth 532 from being disengaged from the slide guide rod 531.

The following explains the operation of the cultivating device 40 of the present invention with reference to the above-mentioned structure:

in the initial state, the cultivating device 40 is as shown in fig. 8, at this time, the cultivating tub 200 is placed on the accommodating recess 110, the regenerated water generated by the sewage treatment station 11 is delivered to the water inlet pipe 51 of the water supply pipe network 50, a certain amount of water exists in the accommodating recess 110, the water level line does not reach the junction chamber 335, the elastic compression-resistant member 321 and the elastic return member 421 are both in a free state, and the electromagnetic valve 313 is in an open state. Further, at this time, the state of the cooperative assembly 500 is as shown in fig. 8, the driving rack 510 is engaged with the driven gear 520, and the driven gear 520 is held in contact with the movable tooth 532;

when the water in the receiving groove 110 needs to be changed, the water draining operation is performed first. Specifically, the water pump 53 is started, the water pump 53 delivers the regenerated water into the pressure tank 310 through the water inlet pipe 51, and since the electromagnetic valve 313 is in an open state at this time, the regenerated water in the pressure tank 310 does not push the pressure piston 320 to slide down, but directly enters the accommodating recess 110 through the electromagnetic valve 313 of the outlet 412. At this time, the water level in the accommodating recess 110 begins to rise, when the water level in the first tube cavity 333 rises to a position higher than the junction cavity 335, the water in the first tube cavity 333 enters the second tube cavity 334 through the junction cavity 335 under the action of pressure, and is finally discharged to the water outlet pipe 52 through the water outlet 332, that is, when the water level is higher than the junction cavity 335, the water in the first tube cavity 333 and the second tube cavity 334 are communicated with each other, so that the water in the accommodating recess 110 is sucked into the negative pressure water suction pipe 330 and is discharged to the water outlet pipe 52 (this process utilizes the siphon principle, and reference may be made to the "justice cup" in the prior art), so that the water in the accommodating recess 110 is substantially emptied. Meanwhile, after a certain amount of regeneration water is injected (when the water level in the accommodating recess 110 is higher than the junction chamber 335), the solenoid valve 313 is closed;

since the solenoid valve 313 is in the closed state, the regeneration water cannot be discharged through the solenoid valve 313, the regeneration water gradually accumulates in the pressure tank 310 and the water pressure gradually rises, so that the pressure piston 320 starts to slide downward and the pressure-resistant elastic member 321 is compressed. The sliding of the pressure piston 320 drives the driving rack 510 to slide downward, and the driving rack 510 drives the driven gear 520 to rotate in a forward direction (counterclockwise as shown in fig. 10) due to the engagement of the driving rack 510 and the driven gear 520. At this time, the movable teeth 532 provide a reaction force to the driven gear 520, so that the driven gear 520 moves downward and engages with the auxiliary rack 530, and thus the driven gear 520 rotating in the forward direction moves downward along the auxiliary rack 530. During this time, the auxiliary piston 420 is pulled by the driven gear 520 to slide downward, and the return elastic member 421 is compressed; and because the auxiliary piston 420 slides, negative pressure is generated in the auxiliary fertilization tank 410, and the nutrient solution in the nutrient solution storage tank 430 is continuously sucked into the auxiliary fertilization tank 410;

then, a new nutrient solution is injected. Specifically, the driving rack 510 and the driven gear 520 may be relatively displaced during driving of the driven gear 520, and finally the driving rack 510 may be disengaged from the driven gear 520. After disengagement, the driven gear 520 is not driven any more, the auxiliary piston 420 starts to slide upward by the return elastic member 421, the driven gear 520 also starts to ascend (during which the driven gear 520 is still engaged with the auxiliary rack 530), and the driven gear 520 rotates in the reverse direction (clockwise as shown in fig. 11). Eventually, the auxiliary piston 420 is reset to the initial state, and the driven gear 520 is again in contact with and caught by the movable tooth 532. In this process, the nutrient solution in the fertilization auxiliary tank 410 is pressed by the auxiliary piston 420 and is discharged from the discharge port 412 into the accommodation groove 110;

subsequently, new regeneration water is injected. Specifically, after the driving rack 510 is disengaged from the driven gear 520, the water pump 53 is suspended, the electromagnetic valve 313 is opened, and the regenerated water in the pressure tank 310 begins to be discharged into the accommodating groove 110 through the electromagnetic valve 313 under the action of the hydraulic and pressure-resistant elastic element 321, and then is mixed with the nutrient solution therein to be configured into a new mixed solution for the absorption of the crops. Moreover, the water level of the mixed liquid after the configuration does not exceed the intersection chamber 335, that is, the mixed liquid in the accommodating recess 110 is not discharged by the negative pressure suction pipe 330. At the same time, the pressure piston 320 starts to rise under the action of the pressure-resistant elastic member 321, and drives the driving rack 510 to rise together. When the driving rack 510 passes the driven gear 520, it is re-engaged with it and drives it to rotate in the reverse direction. At this time, the movable teeth 532 perform an avoiding operation by the avoiding elastic member 533, so that the driven gear 520 can smoothly reverse. Eventually, the incubation device 40 returns to the initial state as shown in fig. 8.

It is emphasized that the cultivating device 40 of the present invention can automatically replace the solution in the receiving recess 110. The solution in the accommodating groove 110 needs to be replaced because the root system of the crops can extend into the accommodating groove 110 through the cultivating pot 200, and the crops can continuously absorb the nutrition and oxygen in the solution, so that the oxygen and the nutrition of the solution in the accommodating groove 110 are continuously reduced, and the solution in the accommodating groove 110 needs to be replaced regularly in order to ensure the normal growth of the crops. Moreover, the automatic water change needs to complete the following two steps, one is to empty the original solution in the accommodating groove 110; secondly, the accommodating groove 110 is filled with regenerated water and nutrient solution according to a certain proportion. The cultivating device 40 of the present invention does not require manual water changing operation, and can change the states and the matching relationship of the water supply assembly 300, the fertilizing assembly 400 and the cooperating assembly 500 by controlling the opening or closing of the water pump 53 and the electromagnetic valve 313 by using a program, so that the original solution in the accommodating recess 110 is emptied by using the siphon principle, and the regenerated water and the nutrient solution are quantitatively injected, and the ratio of the injected regenerated water and the nutrient solution is fixed because the volumes of the pressure tank 310 and the fertilizing auxiliary tank 410 are fixed. Meanwhile, other power sources are not additionally arranged in the whole process. Moreover, a plurality of cultivation devices 40 can share one water pump 53, which also enables a plurality of cultivation devices 40 to simultaneously perform water changing operations without mutual interference, thereby reducing the labor cost and making the grower feel easier.

It is noted that when the driven gear 520 is engaged with the movable teeth 532, the driven gear 520 can be engaged with the auxiliary rack 530 in the forward rotation, and the driven gear 520 can be rotated only in the home position in the reverse rotation. The principle is as follows: when the driven gear 520 is in contact engagement with the movable teeth 532, when the driven gear 520 rotates in a forward direction (counterclockwise in fig. 10), the movable teeth 532 are pushed upward, but since the movable teeth 532 are held by the blocking plate 534, the movable teeth 532 cannot slide upward and generate a reverse force that urges the driven gear 520 downward, so that the driven gear 520 moves downward and engages with the auxiliary rack 530. When the driven gear 520 rotates in the reverse direction (clockwise direction as shown in fig. 11), the movable teeth 532 receive a downward pushing force, and the movable teeth 532 slide down against the elastic force of the avoiding elastic member 533, so as to be out of contact with the driven gear 520 (i.e., perform an avoiding action); after the disengagement, the movable teeth 532 rise and return under the action of the avoidance elastic member 533, and then are pushed by the driven gear 520 again to perform an avoidance action, and the process is repeated until the driven gear 520 does not rotate reversely. It can be seen that the driven gear 520 can be engaged with the auxiliary rack 530 and moved only when the driven gear 520 is rotated in the forward direction; when the driven gear 520 rotates in the reverse direction, the movable teeth 532 perform an avoiding action, so that the driven gear 520 can only rotate in place.

Example two:

as shown in fig. 12 and 13, the cooperation member 500 includes: a resilient latch hook 540, a catch block 550, and a support rod 560. The elastic latch hook 540 is fixedly disposed on the first piston rod 322, the retaining block 550 is fixedly disposed on the second piston rod 422, and the retaining rod 560 is disposed on the base 100. The elastic latch hook 540 has an elastic arm 541 and a barb 542, and the retaining block 550 is provided with a retaining plane 551 and a guiding inclined plane 552.

Next, a specific operation principle of the cultivation device 40 of the present invention is described in conjunction with the above structure (it should be noted that, the second embodiment is similar to the first embodiment in operation principle, so that repeated descriptions will be briefly described in the following description, and the reader can refer to the operation principle part of the first embodiment for understanding.) that:

in the initial state, the cultivating device 40 is as shown in fig. 12, and at this time, the barb 542 of the elastic latch hook 540 abuts against the abutting plane 551 of the retaining block 550, and the water supply assembly 300 and the fertilizer application assembly 400 are also in the initial state;

when the water in the receiving groove 110 needs to be changed, the water draining operation is performed first. Specifically, when the water pump 53 is started, since the solenoid valve 313 is in an open state, the regenerated water delivered into the pressure tank 310 directly enters the accommodating recess 110 through the solenoid valve 313. Further, the water level in the accommodating cavity 110 rises to a position higher than the junction chamber 335, and the negative pressure suction pipe 330 will substantially drain the solution in the accommodating cavity 110 under the siphon principle. Meanwhile, when the water level in the accommodating groove 110 is higher than the intersection chamber 335, the electromagnetic valve 313 is closed;

as the solenoid valve 313 is closed, the regeneration water gradually accumulates in the pressure tank 310, thereby pushing the pressure piston 320 to start sliding downward, and the compression-resistant elastic member 321 is compressed. The pressure piston 320 drives the elastic latch hook 540 to descend together, and since the barb 542 of the elastic latch hook 540 abuts against the abutting plane 551 of the retaining block 550, the elastic latch hook 540 pulls the retaining block 550 to descend together, and further pulls the auxiliary piston 420 to slide downwards. The sliding of the auxiliary piston 420 can generate negative pressure in the auxiliary fertilization tank 410, and the nutrient solution in the nutrient solution storage tank 430 is continuously sucked into the auxiliary fertilization tank 410;

then, a new nutrient solution is injected. Specifically, after the elastic latch hook 540 slides down for a certain distance, the elastic arm 541 contacts and abuts against the abutting rod 560, and under the extrusion of the abutting rod 560, the elastic arm 541 elastically deforms, so that the barb 542 is separated from the abutting plane 551, and thus, the clamping block 550 and the auxiliary piston 420 are no longer subjected to a downward pulling force, so that the auxiliary piston 420 starts to slide upward under the action of the return elastic member 421, and finally the auxiliary piston 420 returns to the initial state. In this process, the nutrient solution in the fertilization auxiliary tank 410 is pressed by the auxiliary piston 420 and discharged from the discharge port 412 into the accommodation groove 110, as shown in fig. 14;

subsequently, new regeneration water is injected. When the elastic latch hook 540 is unhooked from the retaining block 550, the water pump 53 stops working, the electromagnetic valve 313 is opened, and the regenerated water in the pressure tank 310 begins to be discharged into the accommodating groove 110 through the electromagnetic valve 313 under the action of the hydraulic and pressure-resistant elastic member 321, and then is mixed with the nutrient solution therein to prepare a new mixed solution. At the same time, the pressure piston 320 starts to rise under the action of the pressure-resistant elastic member 321, and the elastic latch hook 540 is lifted together. When the elastic arm 541 moves away from the supporting rod 560, the elastic arm 541 can expand outward again under its own elastic force. As the elastic latch hook 540 rises, the barb 542 thereon will touch the guiding inclined plane 552 of the retaining block 550, and since the elastic arm 541 has elasticity, the barb 542 can make an escape motion along the guiding inclined plane 552 after abutting against the guiding inclined plane 552, so that the barb 542 passes over the retaining block 550 and contacts and abuts against the abutting plane 551 again. Eventually, the incubation device 40 returns to the initial state.

It should be noted that, similarly, the culture device 40 of the present embodiment has the same effects as those of the first embodiment, and also has the following features:

1. the automatic water changing operation is realized, and the following two steps are required to be completed, wherein one step is to empty the original solution in the accommodating groove 110; secondly, the accommodating groove 110 is filled with regenerated water and nutrient solution;

2. the ratio of the mixture liquid injected into the receiving groove 110 is controlled. Because the volumes of the pressure tank 310 and the fertilization auxiliary tank 410 are fixed, the proportion of the injected regeneration water and the nutrient solution is also fixed;

3. realize energy and water conservation. The siphon principle is utilized during drainage, and the hydraulic pressure generated by the water pump 53 is utilized during injection of the regenerated water and the nutrient solution, so that the whole water changing process does not need to additionally add other power sources, and the energy conservation is realized; meanwhile, a traditional running water cultivation mode is abandoned, and a water cultivation mode of periodically changing water is adopted, so that the consumption of water resources can be greatly reduced, the waste of the water resources is avoided, and water conservation is realized;

4. the labor cost is reduced. The opening or closing of the water pump 53 and the electromagnetic valve 313 is controlled by a program, so that the states and the matching relations of the water supply assembly 300, the fertilizing assembly 400 and the cooperating assembly 500 can be changed, meanwhile, the plurality of cultivating devices 40 can share one water pump 53, and the plurality of cultivating devices 40 can be simultaneously subjected to water changing operation without mutual interference, so that the labor cost can be reduced, and the growers can feel easier.

In conclusion, the BIM-based rural waste and sewage recycling system 10 can perform ecological recycling and environmental-friendly utilization on the treated reclaimed water so as to meet the requirements of development and construction of rural areas.
