Technical Field

[0001] The present invention belongs to the technical field of prefabricated green house buildings, and in particular relates to a green plant planting structure of a prefabricated green house building. Background Art

[0002] With the development of construction technology, the use of prefabricated components to build houses can improve construction efficiency. At the same time, with the deepening of the green concept, combining houses with green plants has also become the development direction of future house construction, so prefabricated components are needed to match them. For example, in the Chinese invention patent application with application publication number CN114319936A and application publication date 2022.04.12, a prefabricated assembled green house building structure is disclosed, including a house body, a wall and a fixed plate, and the walls of the house body on both sides away from the fixed plate are provided with irrigation mechanisms, and the irrigation mechanism includes a collection frame, a water outlet pipe, a spray pipe and a plurality of nozzles, the collection frame is fixedly connected to the side wall of the wall, and a water pump is installed in the inner cavity of the collection frame, one end of the water outlet pipe is penetrated through the side wall of the collection frame and is connected to the water outlet of the water pump, the spray pipe is connected to the end of the water outlet pipe away from the collection frame, and the plurality of nozzles are connected to the side wall of the spray pipe, and the plurality of nozzles are arranged toward the fixed plate.

[0003] Although the prefabricated green house building structure can collect rainwater, its structure is arranged in an inclined manner. On rainy days, water from high positions is prone to flow to low positions, which can easily cause green plants located in low positions to absorb too much water and be drowned. In addition, the above scheme only collects rainwater simply and lacks a rainwater filtration device. The water flowing down from the roof often contains mud and sand. If there is no rainwater filtration device, the spray pipe is prone to being blocked by mud and sand when it is recycled and sprayed through the spray pipe, and the frequency of later maintenance is high. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a green plant planting structure for a prefabricated and assembled green house building in view of the shortcomings of the prior art. The present invention can ensure that the water level in the water level maintaining unit is always within the rated threshold range on rainy days, thereby avoiding the situation where green plants are drowned on rainy days. When it does not rain, it can also ensure that the roots of green plants can absorb water. When the water level in the water level maintaining unit is lower than the minimum rated water level, the green plants can be automatically watered at a fixed time to prevent the green plants from drowning and sweating to death.

[0005] This scheme is realized through the following technical measures: the green plant planting structure of prefabricated green house building includes Base plate, used to support green plants; The water level maintaining unit is used to receive the water flowing down from the base plate and supply water to the green plants on the base plate. The water level maintaining unit is located at the lower part of the base plate and can move in the vertical direction so that the water level in the water level maintaining unit is always within the rated threshold range on rainy days, and the green plants absorb water from the water level maintaining unit. The spraying device is arranged on the upper part of the base plate and is used for watering the plants on the base plate.

[0006] Preferably, the spraying device is electrically connected to the controller, and when the green plants need to be watered, the controller controls the spraying device to start; The spraying device comprises a spraying cavity fixed on a base plate, and a plurality of water spraying ports are evenly arranged on the spraying cavity.

[0007] Preferably, the water level maintaining unit includes a receiving shell for receiving water, an automatic drainage unit is arranged on the receiving shell, a spring for supporting the receiving shell is arranged at the bottom of the receiving shell, the receiving shell descends in a vertical direction after the amount of water inside the receiving shell increases and has a lower stop position in the descending stroke of the receiving shell, and when the receiving shell reaches the lower stop position, the automatic drainage unit discharges the water in the receiving shell.

[0008] Preferably, grooves are evenly arranged on the upper part of the substrate and a water absorbing member is arranged through the bottom of the groove, and soil for planting green plants is arranged in the groove. When the water level in the water level maintaining unit is within the rated threshold range, the water absorbing member is in contact with the water in the water level maintaining unit.

[0009] Preferably, the substrate is made of a supportive, water-permeable material.

[0010] Preferably, a circulation device is provided between the spraying device and the automatic drainage unit. On rainy days, the automatic drainage unit discharges excess water in the receiving shell into the circulation device for storage, and supplies water to the spraying device when green plants need to be watered.

[0011] Preferably, the circulation device further comprises a filtering device for filtering rainwater discharged from the automatic drainage unit.

[0012] Preferably, a waterproof device supporting the water level maintaining unit is provided at the bottom of the housing, and a drain port communicating with the inner cavity of the waterproof device is provided on the housing, and the waterproof device receives water leaking from the water level maintaining unit and discharges the leaked water from the drain port; The waterproof device includes a support bin and a support plate. The support bin is fixedly arranged at the bottom of the shell. An opening is provided at the top of the support bin. The support plate is horizontally fixed at the opening. The bottom of the inner cavity of the support bin is a self-opening inclined structure. A communication port is provided on the side wall of the support bin at the lower side of the inner cavity bottom. The communication port is aligned with the drainage port of the shell and is connected to each other.

[0013] Beneficial effects of the present invention: The present invention provides a water level maintaining unit, which can float according to the amount of water (that is, the water level maintaining unit drops when the rainwater inside increases, and rises when the rainwater inside decreases), so that the water level in the water level maintaining unit can be guaranteed to be always within the rated threshold range on rainy days, thereby avoiding the situation where green plants are drowned on rainy days. When it is not raining, as the green plants take water from the water level maintaining unit, the water source stored in the water level maintaining unit will gradually decrease. In this way, the water level maintaining unit gradually rises with the rainwater, so that the water level of the water level maintaining unit is always within the rated threshold range, thereby allowing the roots of the green plants to still absorb water when there is no rain. When the water level in the water level maintaining unit is lower than the lowest rated water level, the roots of the green plants cannot absorb water from the water level maintaining unit, and the controller controls the pump body to start at a fixed time, and supplies water to the spray chamber through the water supply pipe, thereby realizing the irrigation of the green plants on the substrate, and preventing the green plants from drowning and sweating.

[0025] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Reference Figure 1-Figure 5 :The green plant planting structure of prefabricated green house building includes Base plate 1, used for receiving green plants; The water level maintaining unit 2 is used to receive the water flowing down from the base plate 1 and supply water to the green plants on the base plate 1. It is located at the lower part of the base plate 1 and can move in the vertical direction, so that the water level in the water level maintaining unit 2 is always within the rated threshold range on rainy days, and the green plants absorb water from the water level maintaining unit 2; The spraying device 3 is arranged on the upper part of the substrate 1 and is used for watering the plants on the substrate 1 .

[0027] The spray device 3 is electrically connected to the controller. When the green plants need to be watered, the controller controls the spray device 3 to start. The spray device 3 includes a spray chamber fixed on the substrate 1, and a plurality of water spray ports are evenly arranged on the spray chamber. When the green plants need to be watered (that is, when the water level in the water level maintaining unit 2 is lower than the minimum rated water level), the roots of the green plants cannot absorb water from the water level maintaining unit 2. The controller controls the pump body to start at a fixed time according to the feedback of the water level sensor, and supplies water to the spray chamber through the water supply pipe, thereby realizing regular watering of the green plants on the substrate 1.

[0028] The lower part of the base plate 1 is provided with a shell 11 for fixedly supporting the base plate 1. The shell 11 is a steel-concrete structure, and the water level holding unit 2 is arranged in the shell 11. When the water level in the water level holding unit 2 is within the rated threshold range, the water level in the water level holding unit 2 is always located above the bottom of the base plate 1, and the roots of the green plants on the base plate 1 can obtain water from the water level holding unit 2. The water level holding unit 2 located at the lower side of the base plate 1 can move in the vertical direction, that is, when the water level holding unit 2 receives rainwater, as the amount of rain received in the water level holding unit 2 gradually increases, when the weight of the receiving shell 22 and the water inside it is greater than the rated load of the spring 23, the water level holding unit 2 moves downward in the vertical direction, so that on rainy days, the rainwater level in the water level holding unit 2 drops as the water level holding unit 2 drops. After the water level keeping unit 2 is configured to move up and down automatically according to the amount of water in the water level keeping unit 2, it can ensure that the water level in the water level keeping unit 2 is always within the rated threshold range on rainy days, thereby avoiding the situation where green plants are drowned on rainy days. When it is not raining, as the green plants take water from the water level keeping unit 2, the water source stored in the water level keeping unit 2 will gradually decrease, so that the spring 23 gradually resets and pushes the water level keeping unit 2 to gradually rise with the rainwater, so that the water level of the water level keeping unit 2 is always within the rated threshold range, so that the roots of the green plants can still absorb water when there is no rain.

[0029] Reference Figure 5-Figure 8 The water level maintaining unit 2 includes a receiving shell 22 for receiving water, the receiving shell 22 is located in the outer shell 11 and can move vertically along the outer shell 11, the substrate 1 is arranged on the top of the outer shell 11, a water level sensor for monitoring the minimum rated water level is arranged in the receiving shell 22, the water level sensor is electrically connected to the controller, an automatic drainage unit 21 is arranged on the receiving shell 22, a spring 23 for supporting the receiving shell 22 is arranged at the bottom of the receiving shell 22, the receiving shell 22 descends in the vertical direction after the amount of water inside it increases and has a lower stop position in the descending stroke of the receiving shell 22, and when the receiving shell 22 reaches the lower stop position, the automatic drainage unit 21 discharges the water in the receiving shell 22.

[0030] As the rainwater continues to increase, when the weight of the receiving shell 22 and the water inside it is greater than the rated load of the spring 23, the receiving shell 22 moves downward and compresses the spring 23. In order to prevent the spring 23 from being crushed, an automatic drainage unit 21 is arranged on the receiving shell 22. The automatic drainage unit 21 includes a first drainage hole 211 and a second drainage hole 212. The first drainage hole 211 is opened at the bottom of the side wall of the receiving shell 22, and the second drainage hole 212 is opened in the side wall of the outer shell 11 corresponding to the lower limit position of the upper end of the spring 23. In the process of the receiving shell 22 descending, the first drainage hole 211 gradually approaches the second drainage hole 212 on the outer shell 11. When the first drainage hole 211 and the second drainage hole 212 intersect, the water in the receiving shell 22 can be discharged through the first drainage hole 211 and the second drainage hole 212.

[0031] Rainwater on the substrate 1 penetrates into the receiving shell 22 through the soil 6 at the bottom of the green plant. When the weight of the receiving shell 22 and the water inside it is greater than the rated load of the spring 23, the receiving shell 22 moves downward and compresses the spring 23. At this time, the receiving shell 22 descends in the outer shell 11 along the vertical direction. When the first drainage hole 211 on the receiving shell 22 descends to the part intersecting with the second drainage hole 212 so that the first drainage hole 211 and the second drainage hole 212 begin to communicate, the rainwater in the receiving shell 22 can be discharged from the first drainage hole 211 and the second drainage hole 212. When the first drainage hole 211 and the second drainage hole 212 are flushed so that the two are completely connected, the receiving shell 22 reaches the lower stop position. When the rain gradually decreases or stops, the water stored in the receiving shell 22 is gradually discharged through the first drainage hole 211 and the second drainage hole 212, and the weight decreases. When the weight of the receiving shell 22 and the water inside it is less than the rated load of the spring 23, the spring 23 begins to reset and gradually lifts the receiving shell 22 upward, so that the first drainage hole 211 and the second drainage hole 212 are staggered, and the water in the receiving shell 22 is no longer discharged from the first drainage hole 211 and the second drainage hole 212. During the lifting and lowering process of the receiving shell 22, the water level in the receiving shell 22 is always within the rated threshold range on rainy days, so that the green plants on the substrate 1 can always absorb water and will not drown due to excessive water.

[0032] Reference Fig.10 : Grooves 12 are evenly arranged on the upper part of the substrate 1, and a water absorbing member 13 is arranged through the bottom of the groove 12. Soil 6 for planting green plants is arranged in the groove 12. When the water level in the water level maintaining unit 2 is within the rated threshold range, the water absorbing member 13 is in contact with the water in the water level maintaining unit 2.

[0033] Since the receiving shell 22 in the water level maintenance unit 2 will float within the rated threshold range when receiving rainwater, the water is transferred by setting the water absorbent 13 to prevent the green plants from absorbing water intermittently. The water absorbent 13 set in the groove 12 penetrates the bottom of the groove 12 and extends into the receiving shell 22. The lower part of the water absorbent 13 completely covers the rated threshold range of the water level in the receiving shell 22. In this way, no matter how the receiving shell 22 floats, the water absorbent 13 can absorb water. The upper part of the water absorbent 13 extends to the upper middle part of the groove 12, and there is soil 6 in the groove 12. When the humidity of the soil 6 decreases, the water absorbent 13 can transfer the water in the receiving shell 22 to the soil 6. The water absorbent 13 is preferably a cotton strip.

[0034] Reference Figure 5 : The substrate 1 is made of a supportive permeable material (such as permeable concrete). When it rains, rainwater can flow directly through the substrate 1 into the receiving shell 22 to prevent the rainwater from all flowing into the groove 12 and flowing into the receiving shell 22 through the groove 12, which may easily cause the green plants to be drowned.

[0035] Reference Figure 1 and Figure 2 : A circulation device 4 is arranged between the spraying device 3 and the automatic drainage unit 21. On rainy days, the automatic drainage unit 21 discharges the excess water in the receiving shell 22 into the circulation device 4 for storage, and supplies water to the spraying device 3 when the green plants need to be watered.

[0036] The circulation device 4 includes a collecting box and a pump body (not shown in the figure). The collecting box is arranged below the outer shell 11. A connecting pipe 42 is arranged between the collecting box and the automatic drainage unit 21. The water discharged from the automatic drainage unit 21 is discharged into the collecting box through the connecting pipe 42. A water supply pipe for supplying water is also arranged on the collecting box. Both ends of the water supply pipe are respectively connected to the collecting box and the spraying chamber of the spraying device 3. The pump body is arranged on the water supply pipe, and the pump body is used to supply the water in the collecting box to the spraying device 3 through the water supply pipe.

[0037] Reference Figure 7-Figure 9The circulation device 4 also includes a filtering device 41 for filtering the rainwater discharged from the automatic drainage unit 21. The filtering device 41 is provided at the connection between the connecting pipe 42 and the automatic drainage unit 21. The water discharged from the automatic drainage unit 21 is filtered by the filtering device 41 before flowing into the collection box, so as to prevent impurities in the rainwater from entering the spraying device 3 and causing the spraying device 3 to be blocked when the rainwater is recycled. The filter device 41 includes a filter box 411, an upper partition 412, a lower partition 413 and filter cotton 414. The filter box 411 is a rectangular structure. The filter box 411 is horizontally arranged on one side of the automatic drainage unit 21. The upper partition 412 and the lower partition 413 are arranged at one end of the filter box 411 that is connected to the automatic drainage unit 21. The filter cotton 414 is arranged at one end of the filter box 411 away from the automatic drainage unit 21. The upper partition 412 and the lower partition 413 are used in pairs, and a plurality of pairs of upper partitions 412 and lower partitions 413 are arranged in the filter box 411 along its length direction. The upper partitions 412 and the lower partitions 413 in each pair are staggered along the length direction of the filter box 411. The rainwater flowing out of the automatic drainage unit 21 enters the filter box 411 mixed with mud and sand, wherein the mud and sand in the rainwater will slowly settle in the filter box 411 and be intercepted by the lower partition 413, and the rainwater after standing is located in the upper layer of the filter box 411 and overflows from the upper part of the lower partition 413, and the upper partition 412 blocks the overflowing rainwater, so that the mud and sand in the rainwater settle downward, and the settled mud and sand are intercepted by the lower partition 413 in the next group, and the upper layer of clean water overflows from the upper part of the lower partition 413, thus realizing multi-stage sedimentation and impurity removal of rainwater, and the rainwater after sedimentation and impurity removal is filtered through the filter cotton 414, so as to ensure that the rainwater entering the collection box will not be mixed with mud and sand, and avoid clogging of the spraying device 3 during spraying.

[0038] Reference Figure 4 and Figure 5 A waterproof device 5 supporting the water level maintaining unit 2 is provided at the bottom of the shell 11, and a drain port connected to the inner cavity of the waterproof device 5 is provided on the shell 11. The waterproof device 5 receives the water leaking from the water level maintaining unit 2 and discharges the leaked water from the drain port.

[0039] The waterproof device 5 includes a support bin 51 and a support plate 52. The support bin 51 is fixedly arranged at the bottom of the housing 11. An opening is provided at the upper part of the support bin 51. The support plate 52 is horizontally fixed at the opening. The bottom of the inner cavity of the support bin 51 is a self-opening inclined structure. A communication port is provided on the side wall of the support bin 51 at the lower side of the inner cavity bottom. The communication port is aligned with the drainage port of the housing 11 and is connected to each other. When water leaks at the bottom of the receiving shell 22, the leaked water can also be promptly led out by the support bin 51, so that rainwater will not gather in the support bin 51, thereby avoiding water leaks on the roof during the use of the house.

[0040] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
