Description

Technical Field

[0001] This utility model relates to the technical field of drought resistance experimental equipment, specifically to the roof of a drought resistance experimental shed. Background Technology

[0002] Water deficit is one of the most common environmental stresses affecting plant productivity. Although vegetable crops are generally cultivated in areas with abundant water, vegetables usually have a large water requirement and require a relatively large amount of water throughout almost the entire growth period. Fruit trees are mostly cultivated in hilly areas and are more susceptible to the effects of water deficit. Therefore, in-depth research on plant drought resistance and drought-resistant breeding is particularly important. The success or failure of drought-resistant breeding largely depends on the amount of resistant resources available and the depth of research. Therefore, the identification, evaluation, and screening of drought resistance of germplasm resources are key links in drought-resistant breeding. Drought resistance experiments are generally conducted in drought resistance experimental greenhouses, where the greenhouse roof is the main receiving part for sunlight and rainfall. Therefore, the greenhouse roof is the main carrier for conducting drought resistance experiments.

[0003] To change the angle at which sunlight enters the experimental shed, the shed roof typically uses a combination of multiple V-shaped light-transmitting panels. However, the existing V-shaped light-transmitting panels on the shed roof are often in fixed positions. Although the angle at which sunlight is received can be changed to simulate drought resistance experiments, the amount of rainwater that can be diffused from the shed roof cannot be changed by altering the spacing of the V-shaped light-transmitting panels. In other words, it is impossible to simulate changing the amount of rainwater entering the shed by changing the spacing of the V-shaped light-transmitting panels, thus affecting the comparative results of rainfall data in drought resistance experiments.

[0004] Therefore, it is necessary to invent a drought-resistant experimental greenhouse roof to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a drought-resistant experimental shed roof. This invention solves the problem that in existing technologies, the V-shaped light-transmitting panels on the experimental shed roof are often in a fixed position. Although the angle of sunlight reception can be changed to simulate drought resistance experiments, the amount of rainwater entering the shed cannot be altered by changing the spacing of the V-shaped light-transmitting panels. This means that the amount of rainwater entering the shed cannot be simulated by changing the spacing of the V-shaped light-transmitting panels, thus affecting the comparative results of rainfall research in drought resistance experiments.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The roof of the drought-resistant experimental shed includes a top frame, multiple side frames located at the corners of the two side walls of the top frame, and a base frame that can be detachably snapped between two side frames on the same side. Each base frame and the top frame are laterally slidably provided with multiple V-shaped light-transmitting plates whose sliding positions can be controlled. A top strip is snapped at the top of the top frame, and a bottom strip is snapped at the top of each base frame. The tops of the two side frames located on different side walls of the top frame but on the same side are rotatably provided with a winding roller, and the winding roller winds up a rain cloth. Slider blocks are synchronously slidably provided on the side of the top strip and inside the bottom strip on the same side, and the two sliders can be detachably snapped with the corners of the rain cloth on both sides respectively.

[0008] When the two sliders on the same side of the top frame slide to the position furthest from the take-up roller, the tarpaulin completely closes the top space formed between the top frame, side frame and bottom frame on that side.

[0009] As a preferred embodiment of this utility model, the portion of the two side walls of the top frame located between the side frames is detachably equipped with guide rails, and the two base frames are also detachably equipped with guide rails on the side closest to the top frame. Both ends of the V-shaped light-transmitting plate are detachably snapped with clips, and the other end of the clips is equipped with a slide block. The slide block can slide laterally along the guide rails and the sliding position can be controlled.

[0010] As a preferred embodiment of this utility model, each of the top strips has a top edge block detachably snapped onto both ends, and the bottom end of the top edge block is detachably abutted against the top end of the top frame. Each of the bottom strips has a bottom edge block detachably snapped onto both ends, and the bottom end of the bottom edge block is detachably abutted against the top end of the base frame. The two take-up rollers rotatably abut against the two side walls of one of the top edge blocks, and the other end of the take-up roller rotatably passes through the bottom edge block and extends to the outside of the bottom edge block.

[0011] As a preferred embodiment of this utility model, both sides of the top strip are provided with grooves for the slider to slide laterally, and the two bottom strips are also provided with grooves for the slider to slide laterally on the side wall near the top frame.

[0012] As a preferred embodiment of this utility model, the slider is provided with a slot for the detachable snap-fit ​​of the rain cloth.

[0013] As a preferred embodiment of this utility model, rain drainage holes are provided on the side walls of the two bottom strips that are far apart from each other, and the rain drainage holes are connected to the sliding groove.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] In this invention, the two ends of the V-shaped light-transmitting plate can slide synchronously along the sides of the top frame and the bottom frame, respectively. Each V-shaped light-transmitting plate can slide independently and lock its sliding position, thereby adjusting the distance between two adjacent V-shaped light-transmitting plates. By controlling the distance between the V-shaped light-transmitting plates, the amount of rainfall passing through the roof and entering the greenhouse can be controlled. In other words, by controlling the distance between the V-shaped light-transmitting plates, a comparative experiment on rainfall in the greenhouse drought resistance experiment can be conducted, avoiding interference with the comparative results of rainfall in the drought resistance experiment. At the same time, a rain cloth with a position controllable by a slider is installed above the experimental greenhouse roof space formed between the top frame, side frames, and bottom frame. This allows the rain cloth to be completely rolled up in the roll-up roller, or to completely close the experimental greenhouse roof space formed between the top frame, side frames, and bottom frame under the sliding traction of the slider, preventing rainwater from entering the experimental greenhouse. This achieves complete rain drainage adjustment of the experimental greenhouse roof, further increasing the control experiment on rainfall in the experimental greenhouse roof, thereby maximizing the satisfaction of the comparative research on rainfall in the drought resistance experiment.

[0023] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0024] This utility model provides, for example Figure 1-5The drought-resistant experimental shed roof shown includes a top frame 1, multiple side frames 2 located at the corners of the two side walls of the top frame 1, and a base frame 3 detachably snapped between two side frames 2 on the same side. Each base frame 3 and the top frame 1 are laterally slidably provided with multiple V-shaped light-transmitting plates 9 whose sliding positions can be controlled. The top of the top frame 1 is snapped with a top strip 4, and the top of each base frame 3 is snapped with a bottom strip 5. The tops of the two side frames 2 located on different side walls of the top frame 1 but on the same side are rotatably provided with a winding roller 11, and the winding roller 11 winds up a rain cloth 12. The sides of the top strip 4 and the bottom strip 5 on the same side are synchronously provided with sliders 14, and the two sliders 14 can be detachably snapped with the corners of the two sides of the rain cloth 12 respectively. The V-shaped light-transmitting plates 9 can change the angle of receiving light on the one hand, and allow rainwater to flow out through the V grooves in the V-shaped light-transmitting plates 9 on the other hand, so as to avoid excessive accumulation of rainwater on the roof of the experimental shed.

[0025] When the two sliders 14 on the same side of the top frame 1 slide to the position furthest from the take-up roller 11, the tarpaulin 12 completely seals the top space formed between the top frame 1, the side frame 2 and the bottom frame 3 on that side.

[0026] The top frame 1 has detachable guide rails 6 installed on the two side walls between the side frames 2. The two bottom frames 3 also have detachable guide rails 6 installed on the side closest to the top frame 1. Both ends of the V-shaped light-transmitting plate 9 can be detachably clipped with brackets 8. The other end of the brackets 8 is equipped with a slide block 7. The slide block 7 can slide laterally along the guide rail 6 and control the sliding position. The slide blocks 7 at both ends of the V-shaped light-transmitting plate 9 slide along the guide rail 6, thereby changing the position of the V-shaped light-transmitting plate 9, that is, changing the spacing between multiple V-shaped light-transmitting plates 9, which in turn changes the amount of rainfall entering the experimental shed through the gaps in the V-shaped light-transmitting plates 9.

[0027] Both ends of the top strip 4 are detachably snapped with top edge blocks 10, and the bottom end of the top edge block 10 is detachably abutted against the top end of the top frame 1. Both ends of each bottom strip 5 are detachably snapped with bottom edge blocks 15, and the bottom end of the bottom edge block 15 is detachably abutted against the top end of the base frame 3. Two take-up rollers 11 rotatably abut against the two side walls of one of the top edge blocks 10, and the other end of the take-up roller 11 rotatably passes through the bottom edge block 15 and extends to the outside of the bottom edge block 15. The drive assembly of the take-up roller 11 is installed at one end of the bottom edge block 15 at the extension of the take-up roller 11. This is a mature existing technology, so it is not shown in the figure.

[0028] Both sides of the top strip 4 are provided with grooves 13 for the slider 14 to slide laterally, and the two bottom strips 5 are also provided with grooves 13 for the slider 14 to slide laterally on the side wall near the top frame 1. The slider 14 slides along the grooves 13, thereby pulling the tarpaulin 12 to slide in the experimental shed top space formed between the top frame 1, the side frame 2 and the bottom frame 3, thereby changing the space covered by the tarpaulin 12.

[0029] The slider 14 has a slot 16 for the detachable snap-fit ​​of the rain cloth 12. The slot 16 facilitates the snap-fit ​​and detachment of the rain cloth 12 and the slider 14.

[0030] Both bottom strips 5 have rain drainage holes 17 on their opposite sides, and the rain drainage holes 17 are connected to the slide groove 13. The rain drainage holes 17 can prevent rainwater from accumulating in the slide groove 13.

[0031] In this invention, the two ends of the V-shaped light-transmitting plate 9 can slide synchronously along the sides of the top frame 1 and the bottom frame 3, respectively. Each V-shaped light-transmitting plate 9 can slide independently and lock its sliding position, thus allowing the spacing between adjacent V-shaped light-transmitting plates 9 to be adjusted. This control of the spacing allows control of the amount of rainfall passing through the roof and entering the greenhouse. In other words, controlling the spacing of the V-shaped light-transmitting plates 9 enables a comparative experiment on the impact of rainfall on drought resistance within the greenhouse, avoiding interference with the comparative results of rainfall data in the drought resistance experiment. Simultaneously, the top frame 1 and the side frames... Above the experimental shed top space formed between the top frame 1, side frame 2, and base frame 3, a rain tarpaulin 12 is installed, the position of which can be controlled by a slider 14. This allows the rain tarpaulin 12 to be completely rolled up inside the winding roller 11, and it can also completely close the experimental shed top space formed between the top frame 1, side frame 2, and base frame 3 under the sliding traction of the slider 14, preventing rainwater from entering the experimental shed. This achieves complete rain drainage adjustment of the experimental shed top, further increasing the control experiment of the experimental shed top for rainfall, thereby maximizing the satisfaction of the comparative study of rainfall in drought resistance experiments.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
