Description

Technical Field

[0001] The present invention relates to the field of building wall and slope greening, and in particular to a modular green wall based on drone intelligent construction and a construction method thereof. Background Art

[0002] Urban high-rise buildings and the numerous steep slopes created by urban construction have become potential sites for increasing green space. Traditional vertical greening primarily relies on planting vines, which suffer from drawbacks such as limited variety, long growth periods, difficulty in controlling morphology, and poor artistic effects. Currently, modular green walls on building walls and slopes are a common approach, with some exploring intelligent green walls, such as:

[0003] Patent CN 114793684 A discloses a modular intelligent vertical greening system for building facades, comprising: a building facade mounting unit with a controller, raindrop sensor, and wind speed sensor mounted sequentially on top; and a greening assembly comprising a greening frame, a transparent panel, a greening planting trough, and a soil moisture sensor. The modular installation of the greening assembly enables intelligent storage and utilization of rainwater, prevents excessive seepage of muddy water, and intelligently protects green plants during extreme winds. The intelligent portion of this invention primarily focuses on rainwater storage and utilization and the post-production protection of green plants; the construction process is not intelligent.

[0004] Patent CN 104542042 A discloses a combined, three-dimensional intelligent landscaping system for landscape gardening. The system includes a rainwater collection and purification system, a water diversion and irrigation system, a greening system, an external electronic control system, and a water storage and purification system. The system achieves water recycling by connecting water diversion and irrigation pipes to a rainwater collector and water storage and purification system, but does not address intelligent improvements to the construction process.

[0005] In summary, green walls are the main development direction of vertical greening in the future. Existing technologies rely on manual operation in the process of building green walls and replacing green plant modules, which cannot achieve mechanization and intelligence in the green wall construction process. The main disadvantages are as follows:

[0006] (1) Manual operation often requires the use of large equipment such as aerial work lifts. Currently, the height of general lifts is about 20 meters, and the highest will not exceed 60 meters. The height of these equipment limits the height of green walls, making it difficult to achieve full green coverage in high-rise or even super-high-rise buildings. In addition, the use of lifting equipment requires a high site, which also limits the scope of use of green walls.

[0007] (2) After the green wall is built, some green plant modules often grow poorly or even wither, and need to be replaced in time. However, even replacing a small piece of green plants requires the use of large equipment such as aerial work lifts, which is inconvenient to operate and extremely costly.

[0008] (3) Working at heights poses great safety risks to operators.

[0009] (4) Due to the difficulty and high cost of replacement, the colors and patterns of existing green walls often remain unchanged, which can easily cause aesthetic fatigue in viewers.

[0010] (5) With the increase in labor costs in the future, the use of manual operation will also greatly increase the cost of building, replacing and maintaining green walls. Summary of the Invention

[0014] In a preferred solution, the green plant base also includes a power mechanism, which includes a telescopic mechanism arranged on the outside of the base plate, a roller is provided at the telescopic end of the telescopic mechanism, a slide groove adapted to the roller is provided on the side of the support plate close to the base plate, a connecting rod is provided on the upper end of the support plate, and a laterally arranged support rod is provided on the outside of the keel, and the support rod and the connecting rod are connected by a pin shaft.

[0015] In a preferred solution, an electromagnet is provided on the outside of the support plate, and the electromagnet adsorbs the green plant module.

[0016] In a preferred solution, the green plant base also includes an electric control system, which includes a power supply. The power supply supplies power to the telescopic mechanism or electromagnet through electric wires. The controller controls the power on and off of the electromagnet and the extension and retraction of the telescopic mechanism. The controller communicates with the operating system. The operating system is used to design the layout pattern of the green wall and control the drone to automatically complete the lifting, disassembly and replacement of the green plant module; an induction mechanism is set directly above the electromagnet. When the upper hook is attracted to directly above the electromagnet, the induction mechanism transmits a signal to the controller, and the operating system responds.

[0017] In a preferred solution, a bracket is provided at the lower end of the outer side of the support plate, and the bracket provides limited support for the green plants.

[0018] In a preferred solution, the bracket includes a supporting plate connected to the supporting plate, and a guardrail is provided on the upper side of the supporting plate.

[0019] In a preferred embodiment, the green plant module includes a shaping frame, a culture matrix is ​​placed inside the shaping frame, a root barrier membrane is laid between the culture matrix and the shaping frame, an upper hook is arranged at the bottom of the shaping frame, a grabbing ring is arranged on the upper side of the shaping frame, and plants are planted in the culture matrix.

[0020] In a preferred solution, both the support plate and the green plant module are provided with identification marks and positioning marks for identification and positioning by a mark reading device on the drone.

[0021] The present invention also provides a construction method of a modular green wall based on intelligent construction by drones, comprising the following steps:

[0022] S1. Build a green plant base on the exterior wall or slope of the building where the green wall is to be installed. First install the keel, then install the base plate, power mechanism and support plate in sequence;

[0023] S2. Design the green wall pattern through the operating system, then lay out the required prefabricated green plant modules near the installation area and start the installation operation;

[0024] S3. The drone takes off and, under the control of the operating system, uses the identification mark to identify the required green plant module. Then, it uses the positioning mark to hover directly above the green plant module. The drone grabs the grabbing ring on the green plant module to complete the selection and grabbing of the green plant module.

[0025] S4. The operating system transmits a signal to the controller on the plant base. The controller controls the telescopic mechanism to extend, rotates the support plate to a horizontal position, and energizes the electromagnet to generate electromagnetic force.

[0026] S5. The drone flies upward with the green plant module, finds the raised pallet through the identification mark, and hovers directly above the pallet through the positioning mark. Then, under the control of the operating system, the drone places the green plant module on the pallet. After placing the green plant module, the drone returns to the starting point.

[0027] S6. After the green plant module is placed on the pallet, the upper hook on the green plant module is attracted by the electromagnet on the pallet and accurately positioned at the entrance of the lower hook. At the same time, the sensing mechanism above the electromagnet transmits a signal to the controller, which de-energizes the electromagnet, retracts the telescopic mechanism, and rotates the pallet vertically. At this time, the green plant module slides along the inclined surface of the pallet, and the upper hook slides into the lower hook. The support plate supports the green plant module, completing the installation of one green plant module.

[0028] S7, repeat steps S3 to S6 until all green plant modules are installed;

[0029] S8. When some green plant modules need to be replaced, the replacement mode is enabled in the operating system, and the green plant module to be replaced is selected. The operating system can then transmit a signal to the controller on the green plant base. The controller lifts the tray corresponding to the module to be replaced to a position where the angle α between the tray and the wall is slightly greater than 90 degrees. The electromagnet is energized to generate electromagnetic force, and the green plant module slides out in the opposite direction, and the upper hook is disengaged from the lower hook. After the upper hook is disengaged, the sensing mechanism above the electromagnet transmits a signal to the controller, and the controller controls the electromagnet to cut off power, shorten the telescopic mechanism, and rotate the tray to a horizontal position. At this time, the drone is guided by the identification mark and the positioning mark to hover above the green plant module, grab the green plant module, move it to the designated position and put it down, completing the removal of the green plant module. Repeat steps S3 to S6 to complete the replacement of the green plant module.

[0030] The modular green wall and its construction method based on drone intelligent construction provided by the present invention have the following beneficial effects:

[0031] 1. It changes the current situation where green walls mainly rely on manual operation for construction and maintenance. It combines drone technology and intelligent construction technology with the construction of green walls, expands the application scope of drone technology, and conforms to the development trend of intelligent construction in the future.

[0032] 2. The entire design, installation, and replacement process of the green wall is intelligent and easy to operate. One person can easily complete the construction process, saving a lot of manpower and reducing labor costs and subsequent maintenance costs.

[0033] 3. The construction process of the green wall no longer requires the use of large equipment such as aerial work lifts, which extends the height and application range of the green wall. At the same time, the installers do not need to work at heights, ensuring personnel safety.

[0034] 4. The rotating tray is equipped with hooks and brackets, which can fix the green plant module by hanging and supporting at the same time to ensure that the green plant module will not fall off from a high altitude and cause danger.

[0035] 5. Various patterns and texts can be formed by combining green plant modules, and the frequency of pattern updates can be increased by using drone intelligent construction. Therefore, green walls can be used as special billboards with extremely high commercial value. The profits from billboards can ensure that there is a source of funds for the construction and maintenance of green plant walls, making up for the defect of high construction costs, forming a virtuous circle, and achieving a win-win situation of ecological and economic benefits. It has extremely high promotion value. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0046] Combine Figures 1 to 8 The specific embodiments of the present invention are described in further detail.

[0047] A modular green wall based on drone intelligent construction includes a green plant base 1, which is arranged on the outer wall of a building or a steep slope. The green plant base 1 includes a keel 101 and a bottom plate 102. In this embodiment, the keel 101 includes a plurality of cross-arranged vertical keels and horizontal keels. The vertical keels are fixed to the outer wall of the building. The vertical keels are fixed to the outer wall of the building through embedded plates, adapters, bolts, etc. The vertical keels can be made of materials such as channel steel; the horizontal keels are fixed to the vertical keels by bolts, and the horizontal keels can be made of materials such as angle steel and channel steel; the vertical keels and the horizontal keels are built into a rectangular grid, which plays a structural support role for the entire green wall device. The bottom plate 102 is embedded in the grid. Specifically, it is fixed to the keel 101 by bolts, and a bottom plate 102 is placed in each grid to block direct contact between the wall and the green plant module 2 to prevent damage to the wall.

[0048] A support plate 103 is provided on the outside of the base plate 102. The support plate 103 can be made of metal or a high-load-bearing polymer material. A lower hook 104 is provided on the outside of the support plate 103. One or more lower hooks 104 can be provided. The lower hooks 104 are L-shaped. An upper hook 201 is provided at the bottom of the plant module 2 to cooperate with the lower hook 104. A grab ring 202 is provided on the upper side of the plant module 2 to facilitate the drone's grasping of the plant module 2.

[0049] Preferably, the green plant base 1 also includes a power mechanism, which includes a telescopic mechanism 105 arranged on the outside of the base plate 102. The telescopic mechanism 105 uses a right-angle electric push rod. The telescopic end of the telescopic mechanism 105 is provided with a roller 106. The side of the support plate 103 close to the base plate 102 is provided with a slide 1031 adapted to the roller 106. The slide 1031 is installed on the center line of the back of the support plate 103, and the roller 106 is embedded therein. A connecting rod 107 is provided at the upper end of the support plate 103, and a horizontally arranged support rod 108 is provided on the outside of the keel 101. The length of the support rod 108 is equal to the length of the telescopic mechanism in the retracted state. The end of the support rod 108 and the end of the connecting rod 107 are connected by a pin shaft, so that the connecting rod 107 can rotate around the hinge position with the support rod 108, thereby realizing the rotation of the support plate 103. It can be rotated downward to a vertical state and upward to a state slightly above the horizontal state.

[0050] An electromagnet 109 is provided on the outside of the support plate 103. The electromagnet 109 attracts the plant module 2, achieving initial adsorption and positioning of the plant module. A sensing mechanism is provided directly above the electromagnet 109. When the upper hook 201 is attracted directly above the electromagnet 109, the sensing mechanism transmits a signal to the controller 1011, which then reacts accordingly with the operating system 3.

[0051] The sensing mechanism may be a pressure sensor connected to the controller 1011 . The pressure sensor senses the pressure signal after the upper hook 201 is adsorbed, and determines whether the upper hook 201 has been initially adsorbed into place.

[0052] In this embodiment, the sensing mechanism uses a feedback circuit, such as Figure 8 As shown, the feedback circuit is provided with two sets of connection contacts 6, and the upper hook 201 has built-in wires and contacts. When the upper hook 201 is adsorbed onto the electromagnet 109, the contacts on the upper hook 201 contact the connection contacts 6 of the feedback circuit, and the feedback circuit is connected. The signal transmitter 7 connected in the feedback circuit transmits the signal to the controller 1011, and the controller 1011 and the operating system 3 then respond accordingly.

[0053] The green plant base 1 also includes an electric control system, which includes a power supply 1010. The power supply 1010 supplies power to the telescopic mechanism 105 or the electromagnet 109 through electric wires. The electric wires are collected in a collection tube, which is arranged along the keel 101. The controller 1011 controls the power on and off of the electromagnet 109 and the extension and retraction of the telescopic mechanism 105. The controller 1011 communicates with the operating system 3 to achieve wireless connection. The controller 1011 receives signals from the operating system 3 to control the telescopic mechanism 105 and the electromagnet 109.

[0054] The operating system 3 is used to design the layout of the green wall and control the drone to automatically complete the installation, removal, and replacement of the green plant modules 2. The operating system 3 is built into the drone's control program as an expansion module. The operating terminal can be installed on a mobile phone, allowing users to design green walls and control the drone using their mobile phone.

[0055] A bracket is provided at the lower end of the outer side of the support plate 103, and the bracket is located at the lowest end of the support plate 103. The bracket provides limited support for the green plant 2. The bracket includes a supporting plate 1012 connected to the support plate 103, and a guardrail 1013 is provided on the upper side of the supporting plate 1012.

[0056] The support plate 1012 can be made into a solid plate or a mesh plate to support the green plant module 2. The guardrail 1013 is composed of a plurality of vertical bars that extend into the branches and leaves of the plants. The bracket plays a role in fixing the green plant module 2 to prevent it from falling off.

[0057] The green plant module 2 includes a shaping frame 203, which is a rectangular mesh frame. Its length is more than twice the length of the drone to ensure that a safe distance is left between the drone and the building wall or slope when placing the green plant module on the pallet 103; the shaping frame 203 can be formed by bundling metal or polymer materials.

[0058] A culture medium 204 is placed within the shaping frame 203. The culture medium 204 can be made of light soil or soilless culture medium. A root barrier film 205 is laid between the culture medium 204 and the shaping frame 203. The root barrier film 205 is fixed to the sides and bottom of the culture medium 204 to prevent plant roots from damaging the support plate 103 and the building wall. PE film can be used.

[0059] The upper hook 201 is set at the bottom of the shaping frame 203, and the grab ring 202 is set on the upper side of the shaping frame 203. Plants are planted in the culture matrix 204. The plants are herbs and small shrubs with strong adaptability, good resistance, and slow growth, such as Schefflera, Pothos, Monstera, Ivy, Chlorophytum, etc., which are pre-planted in the culture matrix 204. The green plant module 2 can be used only after the plants have grown.

[0060] Preferably, both the support plate 103 and the plant module 2 are provided with an identification mark 4 for reading by an identification reading device on the drone, such as a camera, barcode reader, or RFID reader, thereby enabling object recognition through corresponding programs and databases within the operating system. The identification mark 4 on the support plate 103 can be a QR code, barcode, or radio frequency tag. The identification mark 4 on the plant module 2 is easily obscured by plants and can be, for example, a radio frequency tag.

[0061] Preferably, both the support plate 103 and the green plant module 2 are provided with positioning marks 4. The positioning marks 4 on the support plate 103 can be visual marks, infrared LED lamp beads, etc., and the positioning marks 4 on the green plant module 2 can be infrared LED lamp beads, etc. The positioning marks 4 are used to be read by an identification reading device on the drone, such as a camera, and then through the AprilTag / Aruco visual reference library built into the drone system, or by identifying infrared LED lamp beads, and using a drone automatic driving system, such as the FOIA MindSky automatic flight system, to guide the drone to hover above the required green plant module 2 and the corresponding support plate 103.

[0062] A construction method for a modular green wall based on intelligent drone construction includes the following steps:

[0063] S1. Build the green plant base 1 on the exterior wall or slope of the building where the green wall is to be installed. First, install the keel 101, then install the base plate 102, the power mechanism and the support plate 103 in sequence.

[0064] S2. Design the pattern of the green wall through the operating system 3, then lay the required prefabricated green plant modules 2 near the installation area, and start the installation operation.

[0065] S3. The drone takes off. A small or medium-sized rotorcraft, preferably with a payload exceeding 20 kg, is equipped with a telescopic rod and a mechanical claw at its base. The rod can be extended and retracted, and the claw is used to grasp the gripping ring 202 of the plant module 2. The rod and claw are powered by the drone. Under the control of the operating system 3, the drone uses the identification marker 4 to identify the desired plant module 2. The drone then uses the positioning marker 5 to hover directly above the plant module 2. The drone then grasps the gripping ring 202 on the plant module 2, selecting and grasping the plant module 2.

[0066] S4. The operating system 3 transmits a signal to the controller 1011 on the green plant base 1. The controller 1011 controls the telescopic mechanism 105 to extend, rotates the support plate 103 to a horizontal position, and energizes the electromagnet 109 to generate electromagnetic force.

[0067] S5. The drone flies upward with the plant module 2, finds the raised support plate 103 through the identification mark 4, hovers directly above the support plate 103 through the positioning mark 5, and then, under the control of the operating system 3, places the plant module 2 on the support plate 103. After placing the plant module 2, the drone returns to the starting point.

[0068] S6. After the plant module 2 is placed on the support plate 103, the upper hook 201 on the plant module 2 is attracted by the electromagnet 109 on the support plate 103 and accurately positioned at the entrance of the lower hook 104. Simultaneously, the sensing mechanism above the electromagnet 109 transmits a signal to the controller 1011, which de-energizes the electromagnet 109 and retracts the telescopic mechanism 105. The support plate 103 rotates vertically, and the plant module 2 slides along the inclined surface of the support plate 103. The upper hook 201 slides into the lower hook 104, and the support plate 1012 supports the plant module 2, completing the installation of the plant module 2.

[0069] S7. Repeat steps S3 to S6 until all green plant modules 2 are installed.

[0070] S8. When some plant modules 2 need to be replaced, the replacement mode is enabled in the operating system 3. The plant module 2 to be replaced is selected. The operating system 3 then transmits a signal to the controller 1011 on the plant base 1. The controller 1011 lifts the support plate 103 corresponding to the module to be replaced to a position where the angle α between the support plate 103 and the wall is slightly greater than 90 degrees. The electromagnet 109 is energized to generate electromagnetic force, causing the plant module 2 to slide out in the opposite direction, and the upper hook 201 is disengaged from the lower hook 104. After the upper hook 201 is disengaged, the sensing mechanism above the electromagnet 109 transmits a signal to the controller 1011. The controller 1011 controls the electromagnet 109 to de-energize, shorten the telescopic mechanism 105, and rotate the support plate 103 to a horizontal position. At this point, the drone, guided by the identification mark 4 and the positioning mark 5, hovers above the plant module 2, grabs the plant module 2, moves it to the designated location, and places it down, completing the removal of the plant module 2. Steps S3 to S6 are repeated to complete the replacement of the plant module 2.

The controller (1011) turns off the power of the electromagnet (109) and retracts the telescopic mechanism (105). The support plate (103) rotates in the vertical direction. At this time, the green plant module (2) slides along the inclined surface of the support plate (103), and the upper hook (201) slides into the lower hook (104). The support plate (1012) supports the green plant module (2), completing the installation of one green plant module (2). S7, repeat steps S3 to S6 until all green plant modules (2) are installed; S8. When some of the green plant modules (2) need to be replaced, the replacement mode is enabled in the operating system (3), and the green plant module (2) to be replaced is selected. The operating system (3) can then transmit a signal to the controller (1011) on the green plant base (1). The controller (1011) lifts the support plate (103) corresponding to the module to be replaced to a position where the angle α between the support plate (103) and the wall is slightly greater than 90 degrees. The electromagnet (109) is energized to generate electromagnetic force, and the green plant module (2) slides out in the reverse direction. The upper hook (201) is detached from the lower hook (104), and the upper hook is released. After the hook (201) is disengaged, the sensing mechanism above the electromagnet (109) transmits a signal to the controller (1011). The controller (1011) controls the electromagnet (109) to cut off the power, shorten the telescopic mechanism (105), and rotate the support plate (103) to a horizontal position. At this time, the drone is guided by the identification mark (4) and the positioning mark (5) to hover above the green plant module (2), grab the green plant module (2), move it to the designated position and put it down, completing the removal of the green plant module (2). Repeat steps S3 to S6 to complete the replacement of the green plant module (2).
