Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, the utility model is a kind of elevation (over-and-under) type sunshading and thermal insulating structure for plantation dendrobium candidum booth, this sunshading and thermal insulating structure comprises sunshading and thermal insulating net curtain 1, greenhouse pillar 2, flat motion bar 3, suspension ring 4, rolling Timing Belt 8, stepper motor 9, main shaft 6, softly is with 5, a holder curtain groove 11, counterweight tube 12 and hothouse framework 13 members, described stepper motor 9 is fixedly connected on the hothouse framework 13, and the main shaft 6 that is driven by stepper motor shaft extension end is fixed on the greenhouse pillar 2 by base bearing support 7; Soft upper end with 5 is connected to main shaft 6 upper and lower ends to be connected with flat motion bar 3; The upper end of sunshading and thermal insulating net curtain 1 is fixed on flat motion bar 3 upper and lower ends and is fixedly connected on the counterweight tube 12 and places in the holder curtain groove 11; Be provided with transverse link 14 in the bottom of described greenhouse pillar 2, between described transverse link 14 and hothouse framework 13, be provided with band 15.Wherein band 15 is for preventing that sunshading and thermal insulating net curtain 1 from swinging in the process of scrolling.
Preferred embodiment is in the utility model, describedly softly is with 5 upper ends to be connected in main shaft 6 upper and lower ends by rolling Timing Belt 8 to be connected on the flat motion bar 3 by suspension ring 4.
Preferred embodiment also has in the utility model, describedly softly is connected in the bottom that main shaft 6 upper and lower ends are connected in sunshading and thermal insulating net curtain 1 with 5 upper ends by rolling Timing Belt 8.
Be embodiment 1 such as Fig. 2: characteristics are that flat motion bar 3 maintains static in the soft bottom that makes sunshading and thermal insulating net curtain 1 under with 5 multiple spot traction but top integral body moves up and down with flat motion bar 3, nethike embrane operate steadily and sun face without the dead angle, control length can reach more than the hundreds of rice.
Operation principle: at first start stepper motor 9, main shaft 6 forward rotation, promote soft 5 volumes of being with on rolling Timing Belt 8, promote soft length with 5 and shorten this moment, drive flat motion bar 3 and move up, because sunshading and thermal insulating net curtain 1 upper end is being fixedly connected with flat motion bar 3, so sunshading and thermal insulating net curtain 1 moves up with flat motion bar 3, stepper motor 9 cuts out when flat motion bar 3 arrives upper limit position, finishes sunshade or insulation operation this moment.
When stepper motor drives main shaft 6 backward rotation, promote soft length with 5 and extend, flat motion bar 3 is because Action of Gravity Field moves down, and stepper motor 9 cuts out when flat motion bar 3 arrives the lower position, and this moment, the sunshading and thermal insulating curtain was accommodated in the holder act groove 11.
Be illustrated in figure 3 as embodiment 2: open stepper motor 9, main shaft 6 forward rotation, make and promote soft 5 volumes of being with on rolling Timing Belt 8, this moment the lower end be connected to the lifting of sunshading and thermal insulating net curtain 1 bottom soft be with 5 upwards retract, length shortens, drive the bottom of sunshading and thermal insulating net curtain 1 and the counterweight tube 12 that is fixed thereon and together move up, sunshading and thermal insulating net curtain 1 upper end is fixed on the flat motion bar 3; Stepper motor 9 cuts out when counterweight tube 12 arrives upper limit position, finishes sunshade or insulation open operation this moment.
When main shaft 6 backward rotation, promote soft length with 5 and extend, counterweight tube 12 is because Action of Gravity Field moves down, and stepper motor 9 cuts out when counterweight tube 12 arrives the lower position, and this moment, sunshading and thermal insulating net curtain was accommodated in the holder act groove 11.Embodiment 1 and embodiment 2 all can reach sunshading and thermal insulating purpose and effect.Wherein band 15 is for preventing that sunshading and thermal insulating net curtain 1 from swinging in the process of scrolling.
The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
