Description

Technical Field

[0001] The present invention relates to the technical field of agricultural greenhouses, and particularly to an automatic greenhouse roof window structure that is convenient for opening and closing and cleaning. Background Art

[0002] Greenhouses are commonly used equipment in agricultural production, which are used to provide suitable environmental conditions to promote the growth of crops. Generally, roof windows are installed on the roof of the greenhouse to provide additional ventilation and heat dissipation inside the greenhouse, and at the same time adjust the indoor temperature and humidity to ensure the stability and suitability of the greenhouse environment. The roof windows of greenhouses generally adopt an openable design and can be controlled to open and close manually or automatically.

[0003] The existing greenhouse roof windows have the following problems in practical applications:

[0004] 1. Currently, most greenhouse roof windows are not equipped with screen windows, which results in mosquitoes, flies and birds entering the greenhouse. It is not only difficult to drive them out, but they may also damage the planted crops;

[0005] 2. Some roof windows equipped with screen windows need to be frequently cleaned to avoid the screen windows being covered by air pollutants such as dust, which will affect ventilation and heat dissipation. However, due to the high position of the roof, it is difficult to clean the screen windows.

[0006] 3. On rainy days, in order to prevent rainwater from entering the greenhouse, the staff will close the roof window at this time, but this will also limit the ventilation and heat dissipation in the greenhouse, and the moisture and heat cannot be effectively discharged, resulting in an increase in temperature and humidity. High humidity and high temperature are not conducive to the growth of plants and may cause problems such as yellowing of leaves and breeding of pests and diseases.

[0007] In the utility model patent with the Chinese patent number 202010842749, a fully automatic skylight is disclosed, which includes a greenhouse frame. A number of skylights arranged in a grid pattern are laid on the top roof of the greenhouse frame. The skylights can be fully opened or all opened in the same row through the action of the power unit, or can be individually opened at each position. The skylight is composed of a window door above and a window frame below. An automatically retractable blocking net is arranged inside the window frame. In the present invention, the window door is opened by rotating upwards, and the window door drives the window frame to rotate downwards, so that the window frame and the window door are opened to both sides respectively, pulling apart the U-shaped blocking net arranged between them, which is used for the first-stage blocking of the exposed window opening. A screen window is also arranged on the back of the window frame for the second-stage blocking, so as to ensure that when the skylight of the greenhouse is opened, birds and mosquitoes cannot fly in, avoiding troubles for growers.

[0008] Regarding the related technology patent, the inventor believes that: Although the device can prevent birds and mosquitoes from flying into the greenhouse by installing a blocking net, it is inconvenient to clean the blocking net. Since the blocking net is located at a relatively high position such as the top window, ladders or other tools are needed to clean it, which increases the labor intensity of the staff. If the blocking net is not cleaned for a long time, it will be covered by air pollutants such as dust, thus affecting ventilation and heat dissipation. In addition, the durability of the blocking net is poor and it is easily damaged by weathering, requiring regular replacement and maintenance, which increases the cost and workload.

[0009] In the invention patent with Chinese patent number 201710984685, a rain-proof, bird-proof and wind-resistant greenhouse is disclosed, which is mainly used for fruit tree cultivation in southern regions. The greenhouse is a single greenhouse or a multi-span greenhouse composed of several single greenhouses; a single greenhouse includes a main greenhouse body and a top window arranged on the top of the main greenhouse body; the main greenhouse body includes several greenhouse arch bars and a greenhouse film covering the outside of the greenhouse arch bars; side ventilation openings and top ventilation openings are respectively arranged on both sides and the top of the main greenhouse body; the top window includes several upper arch bars, support bars arranged on both sides below the upper arch bars, and an upper greenhouse film covering the outside of the upper arch bars. Anti-bird and anti-insect nets are respectively covered on the side ventilation openings and the top ventilation openings, and a rolling film is covered outside the anti-bird and anti-insect nets. The top ventilation opening is located below the top window. The rain-proof, bird-proof and wind-resistant greenhouse provided by the present invention can meet the four-season environmental requirements for fruit tree planting in most southern regions of our country, with functions of rain-proof, bird-proof, wind-resistant, anti-rust spot, anti-cracking of fruits, and reduction of bagging. Moreover, the structure is simple and the operation is easy, and it can be modified on the basis of the original greenhouse.

[0010] Regarding the related technology patent, the inventor believes that: The device achieves the purpose of preventing birds and insects by covering anti-bird and anti-insect nets on the ventilation openings. However, the anti-bird and anti-insect net at the top ventilation opening is horizontally arranged, resulting in the surface of the anti-bird and anti-insect net being more likely to accumulate pollutants. Moreover, birds build nests on the anti-bird and anti-insect net, thus affecting the ventilation and heat dissipation effects of the anti-bird and anti-insect net, and it is more troublesome to clean manually.

[0011] Therefore, the present invention provides an automatic greenhouse top window structure that is convenient to open and close and clean to solve the above problems. Summary of the Invention

[0012] In view of the above situation, to overcome the defects of the prior art, the present invention provides an automatic greenhouse top window structure that is convenient to open and close and clean. The structure of the present invention is novel, ingeniously conceived, and simple and convenient to operate. It effectively solves the problems that the top window is inconvenient to open and close and inconvenient to clean the window screen, and at the same time avoids mosquitoes and birds from entering the greenhouse, ensuring good ventilation and heat dissipation effects of the top window and avoiding the problem of rainwater intrusion into the greenhouse when opening the window.

[0013] To achieve the above object, the present invention provides the following technical solutions:

[0014] An automated greenhouse roof window structure that is convenient for opening, closing, and cleaning, including a shed frame. A plurality of roof windows are rotatably installed at the upper end of the shed frame. A diamond mesh is fixedly installed at the lower end of each roof window. Arc-shaped straight racks are fixedly installed at the mutually approaching ends of the two diamond meshes. A control motor is fixedly installed inside the shed frame. A speed reducer is fixedly installed at the front end of the control motor. Lifting gears meshing with the respective arc-shaped straight racks are coaxially and fixedly installed on the left and right sides of the speed reducer.

[0015] Preferably, a plurality of cleaning frames are slidably installed back and forth inside the shed frame and are respectively located in front of the respective diamond meshes. Moving sliders are slidably installed on the left and right sides of each cleaning frame. A cleaning roller is rotatably installed between the two moving sliders on the same side. Commutating bevel gears are coaxially and fixedly installed at the left and right ends of each cleaning roller. Side cleaning brushes are rotatably installed at the rear ends of each moving slider. Side bevel gears meshing with the commutating bevel gears are coaxially and fixedly installed at the front ends of each side cleaning brush.

[0016] Preferably, a driving gear is coaxially and fixedly installed in the middle of the cleaning roller. A connecting plate is rotatably installed at the left end of the driving gear. A speed increasing gear meshing with the driving gear is rotatably installed at the front side of the right end of the connecting plate. An arc-shaped bevel rack is fixedly connected to the rear end of the cleaning frame. A rotating bevel gear meshing with the arc-shaped bevel rack is coaxially and fixedly connected to the right end of the speed increasing gear. An arc-shaped sliding groove is formed in the middle of the cleaning frame on the right side of the rotating bevel gear. A reciprocating slider is coaxially and fixedly connected to the right end of the rotating bevel gear and is slidably installed in the arc-shaped sliding groove. A cylindrical slider is fixedly connected to the front side left end of the connecting plate;

[0017] A cleaning motor is fixedly installed on the front side of the cleaning frame. A reciprocating lead screw is coaxially and fixedly installed at the upper end of the cleaning motor. A limiting rod is fixedly installed on the front side of the cleaning frame. A driving plate meshing with the reciprocating lead screw and sliding up and down on the limiting rod is installed. A strip-shaped hole is formed in the driving plate. The cylindrical slider is movably installed in the strip-shaped hole.

[0018] Preferably, pulling gears are coaxially and fixedly installed at the mutually approaching ends of the two lifting gears. Pulling racks meshing with the pulling gears are fixedly connected to the mutually approaching ends of the two cleaning frames.

[0019] Preferably, a rainwater collector is fixedly installed at the lower end of each diamond mesh.

[0020] Preferably, a plurality of cleaning nozzles are fixedly installed on the rear side of each cleaning frame.

[0021] Preferably, a positioning bag is fixed on the shed frame, and a heat preservation film capable of being wound is provided inside the positioning bag.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] 1. This device is equipped with a diamond mesh, effectively avoiding the problem of mosquitoes and birds entering the greenhouse. When the top window is opened, the diamond mesh is located at the lower end of the top window, which can effectively block mosquitoes and birds from entering the greenhouse while maintaining good ventilation and heat dissipation effects. Moreover, the diamond mesh has high rust and anti-destruction capabilities.

[0024] 2. This device has a cleaning rack, cleaning rollers, side cleaning brushes, and cleaning nozzles, effectively achieving the purpose of facilitating the cleaning of the surface of the diamond mesh and ensuring good ventilation and heat dissipation effects of the top window. When cleaning the diamond mesh, first, the top window needs to be closed. The staff uses the controller to turn on the power of the control motor, driving the top window to rotate and close, and at the same time driving the cleaning rack to approach the diamond mesh, making the cleaning rollers fit the front surface of the diamond mesh. At the same time, the two side cleaning brushes move to the left and right sides of the diamond mesh respectively. Then, the staff uses the controller to turn on the power of the cleaning motor, driving the cleaning rollers to rotate and move up and down on the front surface of the diamond mesh to clean the front surface of the diamond mesh, and at the same time driving the side cleaning brushes to rotate and swing on the left and right sides of the diamond mesh to clean the sides of the diamond mesh. The cleaning nozzles spray cleaning liquid to wash the surface of the diamond mesh, which is not only convenient and fast but also saves a lot of manpower.

[0025] 3. This device has a rainwater collector, effectively avoiding the problem of rainwater intrusion into the greenhouse when the window is opened. There are many areas in our country with high temperatures and heavy rains in summer. On rainy and cloudy days, closing the top window will limit the ventilation and heat dissipation in the greenhouse. Therefore, a rainwater collector is set up. Without closing the top window, the rainwater collector can collect the rainwater left by the top window and inject it into the drip irrigation mechanism, not only maintaining continuous ventilation and heat dissipation in the greenhouse but also saving water resources.

Detailed implementation manners

[0036] Regarding the foregoing and other technical contents, features and effects of the present invention, they will be clearly presented in the following detailed description of the embodiments in conjunction with the attached drawings. The contents mentioned in the following embodiments are all referenced to the drawings of the specification. Figures 1 to 7 The following will describe the exemplary embodiments of the present invention with reference to the drawings.

[0037] The following will describe each exemplary embodiment of the present invention with reference to the drawings.

[0038] Embodiment 1, given by Figures 1 - 3 The present invention includes a shed frame 1, and a plurality of transparent glass plates are installed on the shed frame 1. In order to achieve the purpose of conveniently opening and closing the top window 2 and prevent mosquitoes and birds from entering the greenhouse, a plurality of top windows 2 are rotatably installed at the upper end of the shed frame 1. The top window 2 is made of transparent glass material. One end of the top window 2 is hinged, and the other end realizes the open and closed states. At the front side, left side and right side of the lower end of each top window 2, a diamond mesh 3 is fixedly installed respectively. The diamond mesh 3 is made of stainless steel wire and the outer surface is protected by electrostatic spraying treatment, which has high rust prevention and anti-destruction capabilities, good light transmittance, and can block mosquitoes and birds from entering the room at the same time. Arc straight racks 4 are fixedly installed at the mutually approaching ends of the diamond meshes 3 on both sides respectively. A control motor 5 is fixedly installed inside the shed frame 1. The control motor 5 is connected to a power supply, a controller and a time relay. A reducer 6 is fixedly installed at the front end of the control motor 5. A connecting rod is rotatably installed on the reducer 6. Coaxial fixing installations are respectively arranged at the left and right ends of the connecting rod with lifting gears 7 meshing with the respective arc straight racks 4;

[0039] When opening or closing the top window 2, the staff member turns on the power supply of the control motor 5 through the controller, and drives the lifting gears 7 on both sides to rotate coaxially through the connecting rod. The lifting gears 7 engage with the arc-shaped straight racks 4 to move upward or downward, so as to achieve the purpose of opening or closing the top window 2. Through a time relay or a sensor, such as an angle sensor, the opening angle of the top window 2 is realized. The structure is simple and practical. At the same time, when the top window 2 is opened, the wire mesh 3 can prevent mosquitoes and birds from entering the greenhouse.

[0040] Embodiment 2, on the basis of Embodiment 1, is given by Figure 4 In order to achieve the purpose of facilitating the cleaning of the wire mesh, a plurality of cleaning frames 8 are slidably installed front and back in the greenhouse frame 1 and are respectively located in front of each wire mesh 3. The cleaning frame 8 is of an arc structure. Moving chutes are respectively opened at the left and right ends of the cleaning frame 8. Moving sliders 9 are respectively slidably installed in each moving chute. A cleaning roller 10 is rotatably installed between the two moving sliders 9. Cleaning bristles are provided on the cleaning roller 10. Coaxial reversing bevel gears 11 located in the moving sliders 9 are respectively fixedly installed at the left and right ends of each cleaning roller 10. Side cleaning brushes 12 are respectively rotatably installed at the rear ends of each moving slider 9. Side bevel gears 13 meshing with the reversing bevel gears 11 are respectively fixedly installed at the front ends of each side cleaning brush 12;

[0041] When cleaning the wire mesh 3, the staff member closes the top window 2 through the controller, and at the same time drives the cleaning frame 8 to slide backward, so that the cleaning roller 10 is attached to the front end face of the wire mesh 3. At the same time, the two side cleaning brushes 12 respectively move to the left and right sides of the wire mesh 3. Then, while rotating the cleaning roller 10, the cleaning roller 10 is moved up and down reciprocally along the moving chute to clean the front end face of the wire mesh 3. When the cleaning roller 10 moves up and down reciprocally, it can drive the moving sliders 9 on both sides to slide in the moving chute, and at the same time drive the side cleaning brushes 12 to reciprocally move along the moving chute. The rotation of the cleaning roller 10 can drive each reversing bevel gear 11 to rotate. The reversing bevel gear 11 meshes with the side bevel gear 13 to drive each side cleaning brush 12 to rotate, so as to achieve the purpose of cleaning the side surface of the wire mesh 3. The operation is very convenient, the cleaning is clean and fast, and there is no need to invest a lot of manpower.

[0042] Embodiment 3, on the basis of Embodiment 2, is given by Figures 4 - 5Given that a driving gear 14 is coaxially and fixedly installed in the middle of the cleaning roller 10, an installation hole located in front of the driving gear 14 runs through the middle of the cleaning frame 8 from front to back. The left end of the driving gear 14 is rotatably installed with a connecting plate 15. The front side of the right end of the connecting plate 15 is rotatably installed with an accelerating gear 16 meshing with the driving gear 14. The rear end of the installation hole is fixedly connected with an arc-shaped tapered rack 17. The right end of the accelerating gear 16 is coaxially and fixedly installed with a rotating bevel gear 18 meshing with the arc-shaped tapered rack 17. The right end of the installation hole is provided with an arc-shaped sliding groove 19 located on the right side of the rotating bevel gear 18. The right end of the rotating bevel gear 18 is coaxially and fixedly connected with a reciprocating slider movably installed in the arc-shaped sliding groove 19. The front left end of the connecting plate 15 is fixedly connected with a cylindrical slider 20;

[0043] A cleaning motor 21 is fixedly installed on the front side of the cleaning frame 8. The cleaning motor 21 is connected to a power supply, a controller and corresponding sensors. The upper end of the rotating shaft of the cleaning motor 21 is coaxially and fixedly installed with a reciprocating lead screw 22. A limiting rod 23 is fixedly installed on the front side of the cleaning frame 8. A driving plate 24 meshing with the reciprocating lead screw 22 and slidably installed up and down on the limiting rod 23 is provided on the reciprocating lead screw 22. A strip-shaped hole 25 is provided on the driving plate 24. The cylindrical slider 20 is movably installed in the strip-shaped hole 25;

[0044] When cleaning the diamond mesh 3, the staff controls the cleaning motor 21 to be powered on through the controller. The cleaning motor 21 drives the reciprocating lead screw 22 to engage the driving plate 24 to make a reciprocating up and down movement along the limiting rod 23, and drives the cylindrical slider 20 to make a reciprocating up and down movement through the strip-shaped hole 25. Since the moving slider 9 is slidably installed in the moving chute and the reciprocating slider is movably installed in the arc-shaped sliding groove 19, the length of the connecting plate 15 is fixed and the moving chute and the arc-shaped sliding groove 19 are coaxial. When the strip-shaped hole 25 drives the cylindrical slider 20 to make a reciprocating up and down movement, the cylindrical slider 20 slides back and forth in the strip-shaped hole 25 and rotates a certain angle at the same time. In this process, the arc-shaped tapered rack 17 meshes with the rotating bevel gear 18 to rotate, and at the same time drives the accelerating gear 16 to mesh with the driving gear 14 to rotate, thereby driving the cleaning roller 10 to rotate and cleaning the surface of the diamond mesh 3.

[0045] Example 4, on the basis of Example 3, given by Figure 3 and Figure 6 Given that on the mutually approaching ends of the two lifting gears 7 on the connecting rod, a pulling-in gear 26 is coaxially and fixedly installed respectively. On the mutually approaching ends of the two cleaning frames 8, a pulling-in rack 27 meshing with the pulling-in gear 26 is fixedly connected respectively;

[0046] When the top window 2 is closed, the connecting rod drives the pulling-in gear 26 to mesh with the pulling-in rack 27 and slide backward, and at the same time drives the cleaning frame 8 to approach the diamond mesh 3, so that the cleaning roller 10 is attached to the front end face of the diamond mesh 3, and at the same time the two side cleaning brushes 12 respectively move to the left and right sides of the diamond mesh 3, facilitating the next step of cleaning the diamond mesh 3.

[0047] Example 5. On the basis of Example 2, it is given by Figure 2 and Figure 6 that a rainwater collector 29 is fixedly installed at the lower end of each wire mesh 3, and each rainwater collector 29 is connected to the drip irrigation mechanism in the greenhouse through a connecting pipe;

[0048] On rainy and cloudy days, there is no need to close the top window 2. At this time, the rainwater flowing down from the wire mesh 3 is collected by each rainwater collector 29 and then enters the drip irrigation mechanism, which not only maintains continuous ventilation and heat dissipation in the greenhouse, but also saves water resources, and the collected rainwater is used for irrigating agricultural products.

[0049] Example 6. On the basis of Example 2, it is given by Figure 2 and Figure 6 that a plurality of cleaning nozzles 28 are fixedly installed at the rear side of each cleaning frame 8. The cleaning nozzles 28 are connected to a cleaning water pump and a cleaning liquid tank through a connecting pipe, and the cleaning water pump is connected to a controller;

[0050] During the process of cleaning the wire mesh 3, the cleaning liquid sprayed from the cleaning nozzles 28 flushes the surface of the wire mesh 3, avoiding dirt that is not easy to clean sticking to the surface of the wire mesh 3, so as to achieve a better cleaning effect. At the same time, since there is sediment in the rainwater, during the process of the rainwater collector 29 collecting rainwater, part of the sediment will settle to the bottom of the rainwater collector 29. During the process of the cleaning nozzles 28 flushing the surface of the wire mesh 3, some cleaning liquid passes through the wire mesh 3 and sprays into the rainwater collector 29, flushing the sediment deposited in the rainwater collector 29 clean.

[0051] Example 7. It is given by Figure 7 that a positioning bag 30 is fixed on the shed frame 1 to fix one end of the heat preservation film 31. The positioning bag 30 is made of loose material and can accommodate the wound heat preservation film 31. There is a heat preservation film 31 that can be wound in the positioning bag 30. When it is snowy and cold in winter and heat preservation of the shed frame 1 is required, after closing the top window 2, manually unfold the heat preservation film 31 and cover it on the shed frame 1. When it needs to be stored, manually roll up the heat preservation film 31.

[0052] Working principle:

[0053] When opening or closing the top window 2, the staff makes the control motor 5 powered on through the controller, and drives the lifting gear 7 to engage with the arc-shaped straight rack 4 to move up or down, thereby driving the top window 2 and the wire mesh 3 to rotate synchronously, achieving the purpose of opening or closing the top window 2. The wire mesh 3 can play the role of blocking mosquitoes and birds from entering the greenhouse;

[0054] On rainy and cloudy days, there is no need to close the top window 2. At this time, the rainwater flowing down from the wire mesh 3 is collected by each rainwater collector 29 and then enters the drip irrigation mechanism. This not only maintains continuous ventilation and heat dissipation in the greenhouse but also saves water resources, and the collected rainwater is used to irrigate agricultural products.

[0055] When cleaning the wire mesh 3, first, the top window 2 needs to be closed. The staff uses the controller to turn on the power of the control motor 5, which drives the top window 2 to rotate and close. At the same time, it drives the cleaning frame 8 to approach the wire mesh 3, making the cleaning roller 10 fit with the front surface of the wire mesh 3. At the same time, the two side cleaning brushes 12 are respectively moved to the left and right sides of the wire mesh 3. Then, the staff uses the controller to turn on the power of the cleaning motor 21, which drives the cleaning roller 10 to rotate and move up and down on the front surface of the wire mesh 3 to clean the front surface of the wire mesh 3. At the same time, it drives the side cleaning brushes 12 to rotate and swing on the left and right sides of the wire mesh 3 to clean the sides of the wire mesh 3. The cleaning nozzle 28 sprays cleaning liquid to wash the surface of the wire mesh 3, and at the same time, washes the sediment deposited in the rainwater collector 29, so as to achieve the purpose of conveniently cleaning the wire mesh 3, avoiding the wire mesh 3 being covered by air pollutants such as dust, and thus affecting ventilation and heat dissipation.

[0056] When the above controller performs intelligent control, according to the actual needs of those skilled in the art, appropriate time relays, sensors, etc. are installed at corresponding positions to assist in realizing intelligent control.

[0057] Compared with the prior art, the present invention has the following advantages:

[0058] 1. The device has a wire mesh, effectively avoiding the problem of mosquitoes and birds entering the greenhouse. When the top window is opened, the wire mesh is at the lower end of the top window, which can effectively block mosquitoes and birds from entering the greenhouse, while maintaining good ventilation and heat dissipation effects. Moreover, the wire mesh has high rust and anti-destruction capabilities.

[0059] 2. The device has a cleaning frame, a cleaning roller, side cleaning brushes, and a cleaning nozzle, effectively achieving the purpose of conveniently cleaning the surface of the wire mesh, ensuring good ventilation and heat dissipation effects of the top window. When cleaning the wire mesh, first, the top window needs to be closed. The staff uses the controller to turn on the power of the control motor, which drives the top window to rotate and close. At the same time, it drives the cleaning frame to approach the wire mesh, making the cleaning roller fit with the front surface of the wire mesh. At the same time, the two side cleaning brushes are respectively moved to the left and right sides of the wire mesh. Then, the staff uses the controller to turn on the power of the cleaning motor, which drives the cleaning roller to rotate and move up and down on the front surface of the wire mesh to clean the front surface of the wire mesh. At the same time, it drives the side cleaning brushes to rotate and swing on the left and right sides of the wire mesh to clean the sides of the wire mesh. The cleaning nozzle sprays cleaning liquid to wash the surface of the wire mesh, which is not only convenient and fast but also saves a lot of manpower.

[0060] 3. This device is equipped with a rainwater collector, which effectively avoids the problem of rainwater intrusion into the greenhouse when the window is opened. In many regions of our country with high temperatures and heavy rains in summer, when it is rainy and overcast, closing the top window will limit the ventilation and heat dissipation in the greenhouse. Therefore, a rainwater collector is set up so that the top window does not need to be closed. The rainwater collector can collect the rainwater left by the top window and inject it into the drip irrigation mechanism, which not only maintains continuous ventilation and heat dissipation in the greenhouse but also saves water resources.

[0061] Although the content of the present invention has been introduced in detail through the above preferred embodiments, it should be recognized that the above description should not be considered as a limitation of the present invention. After those skilled in the art have read the above content, various modifications and alternatives to the present invention will be obvious. Therefore, the protection scope of the present invention should be defined by the appended claims.
