[0030] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanations of the utility model. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the utility model belongs.

[0031] The following combines the attached drawings to make a detailed description of the utility model. An automatically openable and closable dust-proof and sun-shading green sunshade device for subway station construction disclosed in this embodiment, such asFigure 1 As shown in the figure, it includes multiple sections of tracks 1 arranged along the length direction of the foundation pit. Each section of track 1 consists of side tracks 11 on both sides of the foundation pit; a sliding awning mechanism is arranged on each section of track 1; the sliding awning mechanism is driven by a motor 6, and the motor 6 is connected to a control box 7; inside the construction site enclosure, a wind sensor 8 is provided.

[0032] As Figure 1 shown in the figure, the wind sensor 8 is arranged at a corner inside the construction site enclosure through a column, and is used to monitor the change of the wind force level at the construction site; it should be noted that the wind sensor 8 communicates with a remote mobile terminal, and transmits the information of the wind force change to the remote mobile terminal in real time. Here, the remote mobile terminal can be a mobile phone, enabling the management personnel to obtain the information of the wind force change at the construction site in a timely manner.

[0033] As Figure 1 and Figure 2 shown in the figure, the side track 11 includes square steel columns 111 at both ends, and a slide rail I-beam 112 is fixedly connected to the side of the two square steel columns 111 away from the foundation pit; the sliding awning mechanism includes track pulleys 2, and the track pulleys 2 are arranged on the slide rail I-beam 112. As Figure 2 shown in the figure, a plurality of track pulleys 2 are arranged on the side track 11. It can be understood that corresponding numbers of track pulleys 2 are also arranged on the side track 11 on the other side.

[0034] As Figure 1 and Figure 2 and Figure 3 shown in the figure, the track pulleys 2 on the side tracks 11 on both sides are grouped in pairs, and a support steel wire rope 3 is connected between each pair of track pulleys 2. A sky screen is arranged on multiple support steel wire ropes 3. It can be understood that the sky screen is fixed to the support steel wire ropes 3 by binding wires or straps; the sky screen is made of a special 2000-mesh green anti-aging polyethylene net, which can reduce the diffusion of 90% of PM10 and 70% of PM2.5 at the construction site, and can also block the exposure to sunlight.

[0035] As Figure 2 shown in the figure, two driving pulleys 4 are arranged on each square steel column 111. One driving pulley is arranged on the side of the square steel column 111 parallel to the slide rail I-beam, and the other driving pulley is arranged on the side of the square steel column 111 facing the foundation pit. The two driving pulleys 4 are arranged one above the other.

[0036] In this embodiment, each section of the track 1 includes eight driving pulleys 4. Among them, a section of annular driving steel wire rope 41 is provided on each of the four driving pulleys with a high installation position and the four driving pulleys with a low installation position; two motors 6 are provided on each section of the track 1, separately arranged on the side of the side track 11 away from the foundation pit on both sides. Each annular driving steel wire rope 41 is driven by one motor 6 and circulates between the corresponding four driving pulleys; if the motor on one side is connected to the lower driving steel wire rope, the motor on the other side will be connected to the upper driving steel wire rope; the two motors 6 on each section of the track 1 are controlled by a control box 7, and the motors 6 can rotate forward and backward.

[0037] In this embodiment, the motor 6 is arranged on one side of the track through a column, and the installation height of the motor needs to satisfy that the output wheel at the output end of the motor corresponds to the height of the corresponding driving steel wire rope; it can be understood that driving the driving steel wire rope by the motor is an existing technology. For example, the surface of the output wheel at the output end of the motor is designed with a groove matching the driving steel wire rope to increase the friction force. The driving steel wire rope is wound around the output wheel, and when the motor rotates, the driving steel wire rope can rotate between the four driving pulleys.

[0038] As Figure 2 、 Figure 3 shown, the driving steel wire rope 41 is connected to the track pulley 2 on the side close to the motor through a traction assembly 5. Among them, the track pulley 2 includes an upper pulley 21 and a lower pulley 22. The upper pulley 21 is fixed on the upper support plate 23 through a rotating shaft, and the lower pulley 22 is fixed on the lower support plate 24 through a rotating shaft. The upper support plate 23 and the lower support plate 24 are connected by two bolts 25; the distance between the upper support plate 23 and the lower support plate 24 is greater than the height of the flange of the rail I-beam, and the distance between the upper pulley 21 and the lower pulley 22 is greater than the thickness of the web of the rail I-beam and less than half of the height of the flange of the rail I-beam. The track pulley 2 can freely slide on the rail I-beam without falling off.

[0039] Between the upper support plate 23 and the lower support plate 24, a symmetric double-hole plate 26 is further connected to the bolt 25 on the side close to the foundation pit. The outer bolt 25 is arranged in one hole of the symmetric double-hole plate 26, and a buckle 27 is connected to the other hole of the symmetric double-hole plate 26. One end of the support steel wire rope 3 is connected to the buckle 27.

[0040] As Figure 2 、 Figure 3 shown, a traction assembly 5 is connected inside the buckle 27. The traction assembly 5 includes a cross-shaped channel bar 51. The head of the cross-shaped channel bar is closed and connected inside the buckle 27; the two tail ends of the cross-shaped channel bar 51 are straight segments and are fixedly connected to the driving steel wire rope 41 through a fixing buckle 52; adjacent track pulleys 2 are connected by a steel chain 28, and both ends of the steel chain 28 are fixedly connected to the symmetric double-hole plate 26.

[0041] It is understandable that the motor 6 controls the driving steel wire rope to rotate, so as to drive the track pulley 2 to move, enabling the sky screen net to cover the foundation pit above the section of the track 1; since the circumferences of the rings formed by the lower driving steel wire ropes and the rings formed by the upper driving steel wire ropes may be different, the rotational speed of the motor controlling the driving steel wire rope with a longer circumference length is greater than that of the motor controlling the driving steel wire rope with a shorter circumference length, but it is necessary to ensure that the moving speeds of the same group of track pulleys 2 on the two side tracks 11 are consistent.

[0042] In this embodiment, the control box 7 is arranged on one side of the track 1 through a bracket. The control box 7 includes a stainless steel shell, and a motor controller is arranged inside the control box 7. The motor controller is connected to two motors; instructions are sent to the motor controller through a remote control or a remote mobile terminal to control the start, stop, and reverse of the motors.

[0043] The on-site management personnel use a remote control or a remote mobile terminal to send control instructions to the motor controller in the control box according to the actual construction operation environment, weather, temperature, sunlight exposure, etc., so as to control the start, stop, forward and reverse rotation of the motor 6, and realize the opening and closing of the sky screen net.

[0044] This embodiment also transmits the wind force information monitored by the wind sensor to the remote mobile terminal. When the wind sensor senses that the on-site wind force reaches level 4 or above, the management personnel can know the on-site wind force level through the remote mobile terminal, and can directly send a control signal to the motor controller through the remote mobile terminal, so as to control the start, stop, forward and reverse rotation of the motor 6, and realize the opening and closing of the sky screen net.

[0045] Working principle:

[0046] When the sky screen net needs to be covered and shielded, the motor is controlled to be in the start state through a remote mobile terminal or remote control. The two motors rotate and the rotational speeds of the driving steel wire ropes rotating around the driving pulleys in a cycle are the same. The driving steel wire ropes drive the track pulleys close to the motor side to move towards the motor, and the track pulleys drive each track pulley to unfold in sequence through steel chains, thereby driving the sky screen net to unfold; when the sky screen net completes shielding, the motor is controlled to be in the closed state.

[0047] Similarly, when the sky screen net needs to be opened, the motor is controlled to be in the reverse state through a remote mobile terminal or remote control; after the sky screen net is completely opened, the motor is controlled to be in the closed state.

[0048] Although the specific implementation manners of the present invention are described above in conjunction with the drawings, it is not a limitation to the protection scope of the present invention. Those skilled in the art should understand that on the basis of the technical solution of the present invention, various modifications or deformations that can be made by those skilled in the art without creative labor are still within the protection scope of the present invention.
