Meanwhile, the inner sides of the main curtain sheet 41 and the side curtain sheets 51 are both provided with LED plant growth lamps 6 so as to simulate sunlight.

Further, the main curtain sheet 41 and the side curtain sheets 51 are both PVC rolls, and have a thickness of 2mm to 5mm, preferably 3 mm. If the thicknesses of the main curtain sheet 41 and the side curtain sheets 51 are too small, folding is likely to occur when sliding on the guide rail, and the force provided by the servo motor is difficult to be transmitted to the main curtain sheet 41 and the side curtain sheets 51, so that the main curtain sheet 41 and the side curtain sheets 51 are difficult to ascend and crawl along the guide rail. If the thickness of the main curtain sheet 41 and the side curtain sheet 51 is large, it is difficult to wind the driving shaft 4 and the driven shaft 5. Therefore, the thickness of the device is 2mm-5mm, especially 3 mm.

In addition, the photo-reactor body 2 can culture photosynthetic bacteria in rainy season while improving the service life.

As shown in fig. 2 and 3, a pair of right-angle reducers 13 is disposed in the base 1, and the pair of right-angle reducers 13 are distributed at two ends of the base 1 and are located between the driving shaft 4 and the driven shaft 5. Wherein, a bevel gear set 14 which is meshed with each other is arranged between one end of the driving shaft 4 and the driven shaft 5 which are close to each other and the right-angle reducer 13, therefore, when the driving shaft 4 rotates, the driven shaft 5 can synchronously rotate, and the rotating speed is less than that of the driving shaft 4.

As shown in fig. 2 and 3, a groove 15 is horizontally arranged on one side of the base 1 away from the first through hole 11, the groove 15 is arranged in a long strip shape and is arranged along the length direction of the base 1, and meanwhile, the groove 15 is used for embedding the end portion of the main curtain sheet 41. The outer side of one side of the main curtain sheet 41 embedded in the groove 15 is provided with an insertion hole 42, and the base 1 is horizontally and threadedly connected with an insertion rod 16 for inserting the insertion hole 42, so as to realize locking and fixing of the main curtain sheet 41 and the side curtain sheet 51.

Therefore, when raining, the driving shaft 4 is controlled to rotate, and the driven shaft 5 is driven to rotate together by the cooperation of the bevel gear set 14 and the right-angle speed reducer 13. The driving shaft 4 winds the main curtain sheet 41 down and controls the main curtain sheet 41 to move outwards along the first through hole 11, and the main curtain sheet 41 slides along the outer side wall of the guide rail 3 and finally covers and covers the photoreactor body 2. Finally, the end of the main curtain sheet 41 moves into the groove 15, and then the inserting hole 42 on the main curtain sheet 41 is inserted by rotating the inserting rod 16, so that the main curtain sheet 41 and the side curtain sheets 51 are locked and fixed.

Meanwhile, the driven shaft 5 winds down the side curtain pieces 51 and controls the side curtain pieces 51 to move outwards along the second through holes 12, at this time, the side curtain pieces 51 slide upwards along the inner sides of the pair of first rails 31, and finally, the two ends of the rails are covered, so that the photoreactor main body 2 is covered and covered in all directions. Meanwhile, the LED plant growth lamps 6 on the inner sides of the main curtain sheet 41 and the side curtain sheets 51 can be used as natural light, so that photosynthetic bacteria can be continuously propagated, the cultivation method is suitable for cultivation in plum rain seasons, the cultivation efficiency of the photosynthetic bacteria is improved, and the requirement of purifying the culture water body in the plum rain seasons is met.

Specifically, the following are provided: the main curtain sheet 41 and the side curtain sheets 51 can be locked and fixed at the same time through the matching of the inserted rod 16 and the insertion hole 42 on the main curtain sheet 41. Specifically, the bevel gear set 14 is disposed between one end of the driving shaft 4 and the driven shaft 5 close to each other and the right-angle reducer 13, and since the bevel gear set 14 maintains a meshed state, when the insertion rod 16 is engaged with the insertion hole 42 of the main curtain sheet 41, the driving shaft 4 is restricted from rotating, and when the driving shaft does not rotate, the driven shaft 5 is also restricted from rotating by the bevel gear set 14. At this time, the bevel gear set 14 exerts a self-locking effect.

As shown in fig. 3 and 4, a servo motor 17 for driving the driving shaft 4 to rotate is provided in the base 1, the forward rotation push switch 7 and the reverse rotation push switch 8 are provided on the base 1, and the forward rotation push switch 7 and the reverse rotation push switch 8 control the forward rotation and the reverse rotation of the servo motor 17, respectively.

As shown in fig. 3 and 4, when the forward rotation push switch 7 is pushed down, the driving shaft 4 automatically rotates forward, that is, the main curtain sheet 41 and the side curtain sheets 51 cover the photoreactor main body 2. After the reverse rotation push switch 8 is pressed down, the driving shaft 4 automatically works in reverse rotation. Namely, the main curtain sheet 41 and the side curtain sheet 51 release the covering of the photoreactor body 2.

As shown in fig. 4 and 5, a protective cover 18 covering the reverse rotation push switch 8 is provided on the base 1, an installation pipe 9 covering the forward rotation push switch 7 is further vertically provided on the upper end surface of the base 1, and a water collecting bucket 91 arranged in a flared shape is provided on the upper end of the installation pipe 9.

The control plate 92 is vertically slidably connected to the mounting pipe 9, and is used to press the forward rotation push switch 7.

As shown in fig. 4 and 5, an elastic protrusion 94 abutting against the lower end surface of the control plate 92 is disposed at the middle position of the mounting tube 9 to achieve the primary clamping limit of the control plate 92, and a drainage hole 95 located above the forward rotation push switch 7 is disposed at the outer side of the lower end of the mounting tube 9.

When it rains suddenly and nobody is beside the photo reactor body 2, rainwater accumulates in the water collecting hopper 91 and gradually flows into the installation tube 9. When the amount of accumulated water in the installation pipe 9 is large, the gravity of the rainwater drives the control plate 92 to open the elastic protrusion 94 and move downward. At this time, the control plate 92 strikes the forward rotation push switch 7 to move downward, and the forward rotation push switch 7 is pushed, so that the main curtain sheet 41 and the side curtain sheets 51 cover and cover the photoreactor body 2.

Further, the end of the control plate 92 facing the mounting tube 9 is provided with a gasket (not shown in the drawings) between the control plate 92 and the mounting tube 9. Rainwater above the control panel 92 can be prevented from entering the lower part of the control panel 92 by the sealing gasket, so that the forward rotation push switch 7 cannot contact rainwater, and influence of rainwater on the forward rotation push switch 7 is avoided.

When the control plate 92 moves to the lower part of the drain hole 95, the rainwater is gradually discharged along the drain hole 95 to ensure the normal drainage of the rainwater, so as to prevent the control plate 92 from being damaged by the over-weight water body on the forward-push switch 7.

After the rainfall stops, the whole installation tube 9 is taken down from the forward rotation push switch 7, and then the falling of residual water can be realized. At this time, the pull rod 93 is pulled manually to drive the control plate 92 to move upwards, so that the control plate 92 moves to above the elastic bulge 94, and the resetting of the control plate 92 is realized. Then the reverse rotation push switch 8 is manually controlled to be opened and closed so as to release the covering and covering of the photoreactor main body 2.

Further, a support plate 96 is provided between the base 1 and the forward rotation button switch 7, and the outer side of the support plate 96 is in contact with the inner wall of the mounting pipe 9. In this application, through setting up backup pad 96 in order to raise corotation button switch 7's position height, and locate the outside of backup pad 96 through installation pipe 9 cover to avoid the rainwater of whereabouts to contact with corotation button switch 7 in the rain flower of beating on hitting base 1, thereby further improve the water-proof effects of rotating button switch 7 well.

Further, springs 97 are disposed on the upper end surface of the support plate 96, two springs 97 are disposed on two sides of the forward rotation button switch 7, one end of each spring 97 is fixedly connected to the support plate 96, and the other end of each spring 97 can abut against the control plate 92. The upper end of each spring 97 is flush with the lower edge of the water discharge hole 95 without external force.

When the amount of accumulated water in the installation pipe 9 is large, the gravity of the rainwater drives the control plate 92 to open the elastic protrusion 94 and move downward. At this time, the control plate 92 moves downwards, and the driving spring 97 is stressed and extruded to impact the forward rotation button switch 7, so that the forward rotation button switch 7 is pressed, and the main curtain sheet 41 and the side curtain sheets 51 cover and cover the photoreactor main body 2.

In the above description, the distance between the upper end surface of the forward rotation push button switch 7 and the lower edge of the drain hole 95 is denoted by X, and it can be known from hooke's law that: f ═ KX, so in this application: g _{Control panel} +G _{Pull rod} ＝2F＝2KX。

That is, the weight of the control plate 92 and the weight of the pull rod 93 are equal to the spring forces of the two springs 97 after being compressed by the distance X. Therefore, when rainwater exists in the mounting pipe 9 above the control plate 92, the control plate 92 is driven to be flushed away by the gravity of the rainwater and moved downward. At this time, the control plate 92 moves downward, and the driving spring 97 is pressed by force, so that the forward rotation button switch 7 is inevitably impacted, and the forward rotation button switch 7 is pressed. In addition, the purpose of this application setting spring 97 is for after being pressed to the normal rotation button switch 7, spring 97 can promote control panel 92 to move up for the rainwater in the installation pipe 9 can be more discharge through wash port 95, still avoid pressing to the normal rotation button switch 7 for a long time in addition, because current button switch's sensitivity is higher, therefore the dynamics of pressing should not be too big, whether the person can cause the phenomenon of card pause, and still can reduce normal rotation button switch 7's life after long-term the use.

Further, corotation push switch 7 can also be the switch that control LED vegetation lamp 6 starts, and reversal push switch 8 can also be the switch that control LED vegetation lamp 6 closed.

In the present application, the push switch has a dual-purpose effect, that is, when the forward rotation push switch 7 is pushed, the main curtain sheet 41 and the side curtain sheet 51 cover and cover the photo reactor main body 2, and the LED plant growth lamp 6 is turned on to realize photosynthesis.

Pressing the reverse-rotation push switch 8 can release the main curtain sheet 41 and the side curtain sheets 51 from covering the photoreactor body 2, and simultaneously turn off the LED plant growth lamps 6 to achieve the effect of saving electric quantity.

In addition, this application still provides a scheme, is provided with a lamp source that is used for starting LED vegetation lamp 6 and starts push switch (the attached drawing does not mark) by corotation push switch 7 promptly, and can press corotation push switch 7, lamp source start push switch in step through control panel 92 pushes down to realize the start of LED vegetation lamp 6 and the corotation of servo motor. This is the prior art, and detailed description is not given here, but all technical solutions capable of implementing the above functions should be protected by the present invention.

Furthermore, the servo motor of the application is controlled by a PLC control assembly to realize the forward rotation or the reverse rotation of the output end of the servo motor to required parameters, which is the prior art, and Chinese patent with the publication number of CN210608843U discloses an intelligent servo motor based on the PLC control technology.

By adopting the servo motor with the PLC control assembly, the servo motor can be rotated by a certain amount by pressing the forward rotation press switch 7 and the reverse rotation press switch 8, so that the end part of the main curtain sheet 41 moves into the groove 15.

The specific embodiments are only for explaining the present invention, and the present invention is not limited thereto, and those skilled in the art can make modifications without inventive contribution to the present embodiments as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
