Description

Technical Field

[0001] This invention relates to the field of building greening technology, and more specifically, to a building frame structure used for greening the rooftop of buildings. Background Technology

[0002] Roof greening can be broadly understood as the collective term for landscaping and planting trees and flowers on the roofs, terraces, balconies, or large artificial hills of various ancient and modern buildings, structures, city walls, bridges, etc. Roof greening can increase the area of ​​urban green space and improve the situation of the gradual depletion of original ecological plant communities caused by the hard paving of many urban roads. It plays an indispensable role in protecting the urban environment, alleviating the urban heat island effect, and improving the quality of the living environment. In order to facilitate the construction of roof greening, a special building frame structure is often required.

[0003] For example, Chinese patent CN202110546456.8 discloses a building frame structure for rooftop greening. This patent sets up a brush holder and a collection trough, so that the brush holder can move horizontally in the collection trough and drive the brush head to clean the inner wall of the collection trough, which improves environmental protection. However, the collection trough is open, which makes it easy for more impurities and leaves to be ingested during normal use, thus affecting the water source in the collection trough and the normal survival of the vegetation.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention

A cleaning component is located inside the water storage tank. The tank cover and the tank are connected and fixed by a connecting assembly. The connecting assembly includes a fixing plate 1 located on the top side of the inner wall of the water storage tank and a fixing plate 2 located at the bottom of the inner wall of the tank cover. The fixing plate 1 has a sliding groove, and a sliding member is slidably connected in the sliding groove. A moving rod 1 is connected to the outer surface of the sliding member. The other end of the moving rod 1 is connected to one end of the fixing plate 2. A motor 1 is provided at the top of the other end of the fixing plate 1. The output end of the motor 1 is provided with a moving rod 2. The middle part of the moving rod 2 is connected to the middle part of the moving rod 1 through a connecting shaft. A moving rod 3 is provided at the other end of the moving rod 2. The other end of the moving rod 3 is connected to the other end of the fixing plate 2.

[0008] Preferably, the protective assembly includes support seats located on both sides of the top of the building frame body. A support rod is fixedly connected inside each support seat. Two connecting rods and two connecting pieces are symmetrically arranged on both sides of the top of the support seat. A motor is provided at one end of each connecting piece. A connecting piece is provided at the other end of each of the two connecting rods. The other ends of each connecting piece are connected to both sides of one end of a fixing member. The middle portions of each connecting piece are connected to the other ends of the two connecting pieces. A connecting rod is provided in the middle portion of each of the two connecting pieces. The other ends of each connecting rod are connected to both sides of the middle portion of the fixing member. A support rod is fixedly connected inside the fixing member. The sides of both support rods are connected to a tarpaulin. The ends of both support rods are connected to the tarpaulin.

[0009] Preferably, the cleaning assembly includes a motor base located on one side of the outer surface of the water storage tank. A second motor is provided on the top of the motor base. A motor shaft is provided at the output end of the second motor. A threaded rod is provided at the other end of the motor shaft. A support member is sleeved on the outer surface of the threaded rod. A brush seat is provided at the bottom of the support member. Brush heads are provided around the bottom of the brush seat.

[0010] Preferably, the support member has a connecting hole in the middle that mates with the threaded rod, a threaded hole at the bottom of the support member, and an external thread on the top outer surface of the brush holder that mates with the threaded hole.

[0011] Preferably, the water outlet pipe is equipped with a control valve, and a rainwater sensor is provided on each of the top two sides of the building frame body.

[0012] Preferably, the bottom of the outer surface of the water pipe is provided with several water outlets, and the inner surface of the planting box is provided with several air vents.

[0013] Preferably, the support member is provided with a limiting rod on each of the left and right sides of the threaded rod, and the two ends of the limiting rod are respectively connected to the inner wall of the water storage tank.

[0014] Preferably, a sealing ring is provided around the bottom of the box cover.

[0016] Preferably, the first fixing plate is fixed to the water storage tank by screws, and the second fixing plate is fixed to the tank cover by screws.

[0017] The beneficial effects of this invention are as follows: by setting up the connecting components, on the one hand, the inside of the water storage tank can be cleaned regularly to further improve the cleanliness of the water source; on the other hand, after the water tank is cleaned, the water storage tank can be sealed to prevent the tank opening from being wide open, thus preventing more impurities and leaves from entering and affecting the water source and the normal survival of vegetation.

[0018] By configuring the cleaning components, the second motor drives the threaded rod to rotate, which in turn moves the brush holder and brush head along the direction of the threaded rod inside the water tank. This allows the brush head to clean the inner wall of the water tank, and the cleaned impurities can be removed through the top of the water tank. This improves ease of use, ensures the water quality inside the water tank, and increases the survival rate of vegetation.

[0019] With the protective components in place, when the rain sensor detects rain during heavy rain, the protective components can be activated immediately to protect the green plants and prevent them from being damaged by strong winds and rain.

[0020] The base plate and drainage holes facilitate the drainage of excess water from the plant roots, thus preventing root rot and improving the survival rate of the plants.

[0021] The inclusion of ventilation holes enhances the aeration of the plant roots and facilitates the evaporation of water from the bottom of the substrate, thereby improving the plant's survival rate and increasing its practicality.

[0022] By setting up a soil moisture sensor and control valve, the soil moisture sensor can accurately transmit the dryness and wetness of the soil, thereby controlling the opening and closing of the control valve to achieve the purpose of automatic and reasonable watering, saving manpower.

[0041] In practical applications, during cultivation, soil can be covered on top of the base plate 26, and the plants can be planted in the soil. When the soil moisture sensor 25 at the bottom of the planting box 2 detects that the soil moisture level is too low, it will control the control valve 5 to water the plants. The water source is precisely watered through the water supply pipe 6 and the outlet 43 on the water supply pipe 6. When the soil moisture level is reached, the control valve 5 will stop watering. When it is necessary to clean the water storage tank 3, the motor 18 can be started by controlling the external switch. The rotation of the motor 18 drives the motor shaft 19 to rotate, which in turn drives the threaded rod 20 to rotate. The rotation of the threaded rod 20 drives the support 21 to move, which in turn drives the brush seat 22 and the brush head 23 to move. As the brush seat 22 drives the brush head 23 to move, the brush head 23 will brush against the inner wall of the water storage tank 3. After cleaning, the external switch is used to start motor 31. Motor 31 rotates, causing moving rod 13 to move. Moving rod 13 then moves moving rod 12. Moving rod 12 moves sliding member 11 within sliding groove 10 towards motor 31. Simultaneously, moving rod 13 moves moving rod 35. The movement of moving rods 12 and 35 pushes fixed plate 16 to move. Fixed plate 16 moves the tank cover 7 upwards, completely separating it from the top of the water tank 3, thus facilitating the cleaning of debris swept by brush head 23. When it rains, the rain sensor 42 on the top of the building frame 1 detects rain and activates the protective components on both sides to simultaneously deploy and protect the vegetation from rain. Figure 7 As shown, the rotation of motor 341 will cause connector 135 to rotate to the left. The rotation of connector 135 will cause connector 236 and connector 238 to move. The movement of connector 236 will pull connector 134 to move. The movement of connector 236 and connector 238 will cause fixing 37 to move. The movement of fixing 37 will cause support rod 239 to move to the left. The movement of support rod 239 will stretch the rain cover 40. The support rods 239 on both sides move simultaneously and stretch the rain cover 40. Figure 2 As shown, the vegetation in planting box 2 is covered to prevent damage from rainwater.
