Technical Field
[0001] The utility model relates to the technical field of agricultural greenhouses, and particularly relates to a top skylight structure of an agricultural greenhouse. Background Art
[0002] A greenhouse is a facility used in agriculture to cultivate plants, providing a suitable growth environment for plants.
[0003] In order to achieve ventilation in the greenhouse, skylights are usually installed at the top of the greenhouse. Refer to Figure 1 , a first skylight 2 and a second skylight 3 are provided at the top of the greenhouse 1. The lower end of the first skylight 2 is hinged to the right side wall of the greenhouse 1, and the lower end of the second skylight 3 is hinged to the left side wall of the greenhouse 1. A first telescopic rod 4 is hinged to the right side wall of the greenhouse 1, and the output end of the first telescopic rod 4 is hinged to the second skylight 3. A second telescopic rod 5 is hinged to the left side wall of the greenhouse 1, and the output end of the second telescopic rod 5 is hinged to the first skylight 2.
[0004] When ventilating, start the first telescopic rod 4 and the second telescopic rod 5 to extend, and the first skylight 2 and the second skylight 3 can be driven to open outwards. Figure 1 is the state of the first skylight 2 and the second skylight 3 being open. When it rains, start the first telescopic rod 4 and the second telescopic rod 5 to shorten, and the first skylight 2 and the second skylight 3 can be driven to close. After the first skylight 2 and the second skylight 3 are closed, rainwater can enter the interior of the greenhouse 1 through the gap between the upper ends of the first skylight 2 and the second skylight 3.
[0005] When rainwater enters the greenhouse interior, it will cause oxygen deficiency in the roots of plants; increase the humidity of the plant leaves, hindering photosynthesis; increase the humidity inside the greenhouse, aggravating the breeding and spread of pests and diseases.
[0006] Therefore, how to improve the shielding effect and the protection effect on plants is a technical problem that needs to be solved currently. Summary of the Utility Model
[0007] In view of the above deficiencies in the prior art, the present utility model provides a top skylight structure of an agricultural greenhouse, which can improve the shielding effect and the protection effect on plants.
[0008] In order to achieve the above object, the technical solution adopted by the present utility model is:
[0009] A top skylight structure of an agricultural greenhouse, including the greenhouse. There are a first skylight and a second skylight at the top of the greenhouse. The lower end of the first skylight is hinged to the right side wall of the greenhouse, and the lower end of the second skylight is hinged to the left side wall of the greenhouse. A first telescopic rod is hinged to the right side wall of the greenhouse, and the output end of the first telescopic rod is hinged to the second skylight. A second telescopic rod is hinged to the left side wall of the greenhouse, and the output end of the second telescopic rod is hinged to the first skylight. An activity rod is provided at the upper end of the first skylight. The middle of the activity rod is rotatably connected to the first skylight. The lower end of the activity rod is connected to the first skylight through an elastic member. The elastic member is used to push the lower end of the activity rod away from the first skylight. A shielding plate is provided at the upper end of the activity rod. When the first skylight and the second skylight are closed, the second skylight abuts and cooperates with the activity rod.
[0010] Further, a hidden groove is provided at the upper end of the first skylight, and an activity seat is provided in the middle of the activity rod. The activity seat is rotatably connected to the groove wall of the hidden groove through a rotating shaft.
[0011] Further, a first sealing gasket is provided at the upper end of the first skylight, and a second sealing gasket is provided at the upper end of the second skylight.
[0012] Further, the shielding plate adopts an arc-shaped plate, and the convex surface of the arc-shaped plate faces away from the upper end of the activity rod.
[0013] Further, a drainage groove is provided at the lower end of the activity rod.
[0014] Further, both the front and rear ends of the drainage groove are provided with bent sections that bend downward.
[0015] The beneficial effects of the present utility model are as follows:
[0016] 1. After the first skylight and the second skylight are closed, since the shielding plate can block the gap between the first skylight and the second skylight, the risk of rainwater entering the greenhouse through the gap between the first skylight and the second skylight can be reduced, the shielding effect is improved, and the protection effect on the plants inside the greenhouse is improved.
[0017] 2. After the first skylight and the second skylight are opened, since the lower end of the activity rod is pushed by the elastic member and rotates in the direction away from the first skylight, the shielding plate will not block the position between the first skylight and the second skylight, avoiding affecting the air flow and ensuring the ventilation effect.
[0018] 3. Even if rainwater enters through the gap between the first skylight and the second skylight, the rainwater can flow downward along the activity rod and gather in the drainage groove, and then flow downward from the bent sections at the front and rear ends of the drainage groove. Since the bent sections are close to the front and rear sides of the greenhouse, the rainwater flowing downward from the drainage groove can flow close to the front and rear sides of the greenhouse and will not pour on the plants in the middle area of the greenhouse, which can further improve the protection effect on the plants.
[0019] 4. When a first gasket is installed at the upper end of the first skylight and a second gasket is installed at the top of the second skylight, the first gasket and the second gasket can further block the gap between the first skylight and the second skylight, further improving the sealing performance and further enhancing the protection effect on plants.
[0020] 5. When the first gasket and the second gasket are aged due to long-term use, since the baffle is a plate structure and has a longer service life, the shielding effect can be guaranteed, and the protection effect on plants can be ensured.
[0021] 6. The shielding action of the baffle does not require an additional power source for driving. It can be realized by means of the closing actions of the first skylight and the second skylight, and the structure is simple and reliable. Description of the Drawings

[0034] Embodiment:
[0035] See Figures 2 to 8 , a top skylight structure of an agricultural greenhouse 1, including a greenhouse 1, a first skylight 2, a second skylight 3, a first telescopic rod 4, a second telescopic rod 5, a movable rod 6, a baffle 7, an elastic member 8, and a drainage groove 9.
[0036] See Figure 8 , the first skylight 2 and the second skylight 3 are both located at the top of the greenhouse 1. The lower end of the first skylight 2 is hinged to the upper end of the right side wall of the greenhouse 1. The lower end of the second skylight 3 is hinged to the upper end of the left side wall of the greenhouse 1. A first telescopic rod 4 is hinged to the right side wall of the greenhouse 1, and the output end of the first telescopic rod 4 is hinged to the middle of the second skylight 3. A second telescopic rod 5 is hinged to the left side wall of the greenhouse 1, and the output end of the second telescopic rod 5 is hinged to the middle of the first skylight 2.
[0037] In this embodiment, both the first telescopic rod 4 and the second telescopic rod 5 can adopt telescopic devices such as oil cylinders, air cylinders, or electric push rods.
[0038] A plurality of hidden grooves 21 and a plurality of movable rods 6 are provided at the upper end of the first skylight 2. In this embodiment, see Figure 4 , both the hidden grooves 21 and the movable rods 6 are provided with two. See Figure 5 , a movable seat 61 is provided in the middle of the movable rod 6. The movable seat 61 and the movable rod 6 are an integral structure. One movable seat 61 is correspondingly provided in one hidden groove 21, and the movable seat 61 is rotationally connected to the groove wall of the hidden groove 21 through a rotating shaft.
[0039] See Figure 8 , a baffle 7 is fixedly installed at the upper end of the movable rod 6. The baffle 7 adopts an arc-shaped plate, and the convex surface of the arc-shaped plate faces away from the upper end of the movable rod 6. The baffle 7 can adopt stainless steel plates.
[0040] See Figure 8, the lower end of the movable rod 6 is connected to the first skylight 2 through an elastic member 8. The elastic member 8 is a spring. One end of the spring is fixedly installed on the lower surface of the first skylight 2, and the other end of the spring is fixedly installed on the lower end of the movable rod 6. The elastic member 8 is used to push the lower end of the movable rod 6 away from the first skylight 2.
[0041] See Figure 8 , a drainage groove 9 is fixedly installed at the lower end of the movable rod 6. See Figure 7 , bending sections 91 that bend downward are provided at both the front and rear ends of the drainage groove 9.
[0042] In addition, see Figure 2 , a first sealing gasket 22 is fixedly installed at the upper end of the first skylight 2. In order to avoid the position where the movable rod 6 is located, first sealing gaskets 22 are provided at the position between the two movable rods 6 and on the side where the two movable rods 6 are away from each other. A second sealing gasket 31 is fixedly installed at the upper end of the second skylight 3. Both the first sealing gasket 22 and the second sealing gasket 31 can be made of rubber gaskets.
[0043] The working principle of this embodiment is as follows:
[0044] (1) When opening the first skylight 2 and the second skylight 3 at the top of the greenhouse 1:
[0045] First, start the first telescopic rod 4 to extend. The output end of the first telescopic rod 4 pushes the second skylight 3, causing the second skylight 3 to rotate counterclockwise with the rotation connection point between the lower end of the second skylight 3 and the left side wall of the greenhouse 1 as the rotation center, so that the second skylight 3 changes from the state shown in Figure 9 Figure (c) to Figure (b) in the figure, realizing the opening of the second skylight 3;
[0046] When the second skylight 3 is opened, the second skylight 3 leaves the left side surface of the movable rod 6. The movable rod 6 is no longer pressed by the second skylight 3. The elastic member 8 located at the lower part of the movable rod 6 can be stretched, causing the lower end of the movable rod 6 to rotate in a direction away from the first skylight 2.
[0047] Then, start the second telescopic rod 5 to extend. The output end of the second telescopic rod 5 pushes the first skylight 2, causing the first skylight 2 to rotate clockwise with the rotation connection point between the lower end of the first skylight 2 and the right side wall of the greenhouse 1 as the rotation center, so that the first skylight 2 changes from the state shown in Figure 9 Figure (b) to Figure (a) in the figure;
[0048] When both the first skylight 2 and the second skylight 3 are in the state shown in Figure 9 Figure (a) in the figure, both the first skylight 2 and the second skylight 3 are fully opened. After the first skylight 2 and the second skylight 3 are opened, ventilation can be carried out inside the greenhouse 1.
[0049] Moreover, since the lower end of the movable rod 6 is pushed by the elastic member 8 and rotates away from the first skylight 2, the baffle 7 will not block the position between the first skylight 2 and the second skylight 3, avoiding affecting the air flow and ensuring the ventilation effect.
[0050] (2) When closing the first skylight 2 and the second skylight 3 at the top of the greenhouse 1:
[0051] First, start to shorten the second telescopic rod 5. The output end of the second telescopic rod 5 pulls the first skylight 2, causing the first skylight 2 to rotate counterclockwise with the rotation connection between the lower end of the first skylight 2 and the right side wall of the greenhouse 1 as the rotation center, so that the first skylight 2 changes from the Figure 9 state of Figure (a) in to the state of Figure (b), realizing the closing of the first skylight 2;
[0052] Then, start to shorten the first telescopic rod 4. The output end of the first telescopic rod 4 pulls the second skylight 3, causing the second skylight 3 to rotate clockwise with the rotation connection between the lower end of the second skylight 3 and the left side wall of the greenhouse 1 as the rotation center, so that the second skylight 3 changes from the Figure 9 state of Figure (b) in to the state of Figure (c), realizing the closing of the second skylight 3;
[0053] Moreover, during the closing process of the second skylight 3, the upper end of the second skylight 3 abuts against the left side surface of the movable rod 6. As the second skylight 3 continues to close, the upper end of the second skylight 3 pushes the movable rod 6, causing the movable rod 6 to rotate against the elastic force of the elastic member 8, so that the lower end of the movable rod 6 approaches the first skylight 2, and the movable rod 6 gradually changes to a vertical state.
[0054] When both the first skylight 2 and the second skylight 3 are in the Figure 9 state of Figure (c) in, both the first skylight 2 and the second skylight 3 are completely closed. At this time, the movable rod 6 is in a vertical state, and the baffle 7 located at the upper end of the movable rod 6 blocks the gap between the first skylight 2 and the second skylight 3.
[0055] After the first skylight 2 and the second skylight 3 are closed, since the baffle 7 can block the gap between the first skylight 2 and the second skylight 3, the risk of rainwater entering the greenhouse 1 from the gap between the first skylight 2 and the second skylight 3 can be reduced, the shielding effect is improved, and the protection effect on the plants inside the greenhouse 1 is improved.
[0056] Even if rainwater enters through the gap between the first skylight 2 and the second skylight 3, the rainwater can flow downward along the movable rod 6 and gather into the drainage trough 9, and then flow downward from the bent sections 91 at the front and rear ends of the drainage trough 9. Since the bent sections 91 are close to the front and rear sides of the greenhouse 1, the rainwater flowing downward from the drainage trough 9 can flow close to the front and rear sides of the greenhouse 1 and will not wet the plants in the middle area of the greenhouse 1, which can further improve the protection effect on the plants. Moreover, drainage ditches can be dug on the land at the front and rear sides inside the greenhouse 1 so that the rainwater can be discharged through the drainage ditches.
[0057] When the first sealing gasket 22 is installed at the upper end of the first skylight 2 and the second sealing gasket 31 is installed at the top of the second skylight 3, the first sealing gasket 22 and the second sealing gasket 31 can further block the gap between the first skylight 2 and the second skylight 3, which can further improve the sealing performance and further enhance the protection effect on the plants.
[0058] When the first sealing gasket 22 and the second sealing gasket 31 are aged due to long-term use, since the baffle 7 is a plate structure and has a longer service life, the shielding effect can be guaranteed, and the protection effect on the plants can be ensured.
[0059] In addition, the shielding action of the baffle 7 does not require an additional power source for driving and can be realized by means of the closing actions of the first skylight 2 and the second skylight 3, and the structure is simple and reliable.
[0060] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these changes and modifications.
