Description

Technical Field

[0001] This utility model relates to the field of agricultural greenhouses, and in particular to a rapid drainage structure for agricultural greenhouses. Background Technology

[0002] Agricultural greenhouses, also known as plastic greenhouses or plastic sheds, are agricultural production plastic greenhouse facilities with a frame made of materials such as steel pipes, steel, bamboo and wood, covered with plastic film, glass or polycarbonate panels, and equipped with supporting facilities such as ventilation, shading and irrigation.

[0003] To achieve rapid drainage and prevent direct impact from rainwater, some existing greenhouses use fixed protective panels installed on the top of the greenhouse. These panels are often installed at an angle to cover the top of the greenhouse, allowing rainwater to slide down smoothly. Extended eaves are installed on the outside of the protective panels to divert rainwater outside the greenhouse, reducing the erosion of the greenhouse film and walls.

[0004] During rainy days, the impact of raindrops can easily damage the greenhouse film. Some existing protective structures install protective panels on the top of the greenhouse to prevent rainwater from directly impacting the film and to facilitate rapid drainage. However, these panels are mostly fixed. While they can protect the greenhouse to some extent, they continuously block sunlight on sunny days, resulting in insufficient light intensity inside the greenhouse. This affects the photosynthetic efficiency of crops and hinders their normal growth and development. Therefore, a rapid drainage structure for agricultural greenhouses is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rapid drainage structure for agricultural greenhouses, aiming to solve the problem that the protective panels used in some existing greenhouses are mostly fixed, resulting in insufficient sunlight inside the greenhouse on sunny days due to continuous shading, which affects crop growth.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a rapid drainage structure for agricultural greenhouses, including a greenhouse, with an adjustment mechanism and a filtration and cleaning mechanism provided on the outer wall of the greenhouse. The adjustment mechanism includes a support block, the outer wall of which is fixedly connected to the outer wall of the greenhouse. A support frame is detachably connected to the outer wall of the support block via a screw. A slider is slidably connected to the inner surface of the support block. An arc-shaped protective plate is detachably connected to the top of the slider via a screw. The outer wall of the arc-shaped protective plate is slidably connected to the inner wall of the support frame. A threaded rod is rotatably connected to the inner wall of the support frame. The inner wall of the slider is threadedly connected to the outer wall of the threaded rod via a threaded sleeve.

[0007] As a further description of the above technical solution:

[0008] The adjustment mechanism also includes a motor housing, the outer wall of which is fixedly connected to the outer wall of the greenhouse.

[0009] As a further description of the above technical solution:

[0010] The adjustment mechanism also includes a motor, the outer wall of which is fixedly connected to the inner wall of the motor housing, and the output shaft of the motor and the threaded rod are fixedly connected at one end close to each other.

[0011] As a further description of the above technical solution:

[0012] The adjustment mechanism also includes a pulley whose inner wall is fixedly connected to the outer wall of the motor output shaft.

[0013] As a further description of the above technical solution:

[0014] The filtration and cleaning mechanism includes a collection frame, the outer wall of which is fixedly connected to the outer wall of the greenhouse, and a filter screen is fixedly connected to the inner wall of the collection frame.

[0015] As a further description of the above technical solution:

[0016] The filtration and cleaning mechanism also includes a threaded rod II, the outer wall of which is rotatably connected to the inner wall of the collection frame, and a slider II is threadedly connected to the outer wall of the threaded rod II via a threaded sleeve, the outer wall of which is slidably connected to the inner wall of the collection frame.

[0017] As a further description of the above technical solution:

[0018] The filtration and cleaning mechanism also includes a cleaning scraper, the side wall of which is fixedly connected to the side wall of the second slider, and a second pulley is fixedly connected to the outer wall of the threaded rod away from the collection frame. The second pulley is connected to the first pulley via a belt.

[0019] As a further description of the above technical solution:

[0020] The filtration and cleaning mechanism also includes a connecting pipe, the top end of which is fixedly connected to the bottom of the collection frame, and the bottom end of which is fixedly connected to a collection box.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by setting an adjustment mechanism, the arc-shaped protective plate can be quickly unfolded on rainy days to protect the greenhouse film from damage caused by raindrops. On sunny days, the protective plate can be retracted to minimize shading and ensure sufficient sunlight enters the greenhouse to meet the light needs of crop growth. This avoids insufficient light due to long-term coverage by the protective structure, which would affect the photosynthetic efficiency and growth and development of crops.

[0023] 2. In this utility model, by setting a filter cleaning mechanism, impurities can be prevented from accumulating and hardening on the filter screen surface, preventing filter screen blockage that leads to poor rainwater drainage and filtration failure, ensuring normal operation of rainwater collection, while extending the service life of the filter screen and reducing the frequency of replacement.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3The present invention provides an embodiment of a rapid drainage structure for an agricultural greenhouse, comprising a greenhouse 1. An adjustment mechanism 2 and a filtration and cleaning mechanism 3 are provided on the outer wall of the greenhouse 1. The adjustment mechanism 2 includes a support block 211, the outer wall of which is fixedly connected to the outer wall of the greenhouse 1. A support frame 213 is detachably connected to the outer wall of the support block 211 via a screw 212. The support block 211 provides support for the support frame 213. A slider 214 is slidably connected to the inner surface of the support block 211. The slider 214 can slide flexibly within the support block 211, providing guidance for the movement of the arc-shaped protective plate 216. 4. An arc-shaped protective plate 216 is detachably connected to the top via screw 215, facilitating the disassembly and replacement of the arc-shaped protective plate 216 and improving maintenance convenience. The outer wall of the arc-shaped protective plate 216 is slidably connected to the inner wall of the support frame 213, making the movement of the arc-shaped protective plate 216 more stable and reliable. The inner wall of the support frame 213 is rotatably connected to a threaded rod 217, providing a power transmission component for the movement of the slider 214. The inner wall of the slider 214 is threadedly connected to the outer wall of the threaded rod 217 via a threaded sleeve, realizing the synchronous movement of the slider 214 through threaded transmission, thereby controlling the extension and retraction of the arc-shaped protective plate 216.

[0032] Reference Figures 1-3 The adjustment mechanism 2 also includes a motor housing 218, whose outer wall is fixedly connected to the outer wall of the greenhouse 1, protecting the motor 219 from external environmental influences. The adjustment mechanism 2 also includes a motor 219, whose outer wall is fixedly connected to the inner wall of the motor housing 218, providing power to the entire adjustment mechanism 2 and enabling automated adjustment of the arc-shaped protective plate 216. The output shaft of the motor 219 is fixedly connected to one end of the threaded rod 217, ensuring that power can be effectively transmitted to the threaded rod 217. The adjustment mechanism 2 also includes a pulley 220 whose inner wall is fixedly connected to the outer wall of the output shaft of the motor 219, used to transmit the power of the motor 219 to the filter cleaning mechanism 3, realizing functional linkage.

[0033] Reference Figure 1 , Figure 4The filtration and cleaning mechanism 3 includes a collection frame 311, whose outer wall is fixedly connected to the outer wall of the greenhouse 1, effectively collecting rainwater flowing down from the top of the greenhouse 1. A filter screen 312 is fixedly connected to the inner wall of the collection frame 311, filtering impurities in the rainwater to ensure its cleanliness. The filtration and cleaning mechanism 3 also includes a threaded rod 313, whose outer wall is rotatably connected to the inner wall of the collection frame 311, providing power transmission for the movement of the slider 314. The outer wall of the threaded rod 313 is threadedly connected to the slider 314 via a threaded sleeve, driving the slider 314 to move, thus moving the cleaning scraper 315. The outer wall of the slider 314 is slidably connected to the inner wall of the collection frame 311, allowing the slider 314 to move. The movement of the filter cleaning mechanism 3 is more stable. The filter cleaning mechanism 3 also includes a cleaning scraper 315. The side wall of the cleaning scraper 315 is fixedly connected to the side wall of the slider 314, which can clean the impurities on the filter screen 312 in time and prevent the filter holes from clogging. The outer wall of the threaded rod 313 away from the collection frame 311 is fixedly connected to the pulley 316. The pulley 316 is connected to the pulley 220 through the belt, realizing the power linkage between the adjustment mechanism 2 and the filter cleaning mechanism 3. The filter cleaning mechanism 3 also includes a connecting pipe 317. The top end of the connecting pipe 317 is fixedly connected to the bottom of the collection frame 311, and the bottom end of the connecting pipe 317 is fixedly connected to the collection box 318, which smoothly introduces the filtered rainwater into the collection box 318 for storage, which is convenient for subsequent use.

[0034] Working principle: When rapid drainage is needed during rainy days, the motor 219 inside the motor housing 218 is activated. The output shaft of the motor 219 drives the fixedly connected threaded rod 217 to rotate. This causes multiple sliders 214, threaded to the outer wall of the threaded rod 217, to slide synchronously on the inner surface of the support block 211. These sliders 214 then drive multiple arc-shaped protective plates 216 to move synchronously, exposing the arc-shaped protective plates 216 from inside the support frame 213, thus protecting the top of the greenhouse 1. 216 can prevent rainwater from directly impacting greenhouse 1. Rainwater can flow into the collection frame 311 through the arc design of the arc-shaped protective plate 216. The filter screen 312 can filter impurities in the rainwater. Then, it can enter the collection box 318 for storage and collection through the connecting pipe 317. On sunny days, the motor 219 can be started in reverse to make the threaded rod 217 rotate in the opposite direction, so that the arc-shaped protective plate 216 moves into the support frame 213, thereby reducing the obstruction of the top of greenhouse 1 and meeting the light requirements for the growth of crops inside greenhouse 1.

[0035] When the support frame 213 or the arc-shaped protective plate 216 is damaged and needs to be replaced, the screw 212 can be removed so that the support block 211 is no longer fixed to the support frame 213 by the screw 212, so that the damaged support frame 213 can be replaced. Then, the screw 215 on the slider 214 can be removed so that the slider 214 is no longer fixed to the arc-shaped protective plate 216 by the screw 215, so that the damaged arc-shaped protective plate 216 can be replaced.

[0036] When the output shaft of motor 219 rotates, it drives pulley 220 to rotate. Through the transmission of the belt, pulley 316 rotates, which in turn drives threaded rod 313 to rotate. This, in turn, drives slider 314, which is threaded to the outer wall of threaded rod 313, to move. Slider 314 can drive cleaning scraper 315 to clean filter screen 312, preventing impurities from clogging the filter screen and affecting the filtration effect.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
