Description

Technical Field

[0001] The present application relates to the technical field of greenhouses, and in particular to an automatic opening and closing mechanism for a sunshade net. Background Art

[0002] In the field of agricultural greenhouse cultivation, the application of sunshade nets plays an indispensable role. It not only cleverly regulates the light intensity in the greenhouse and maintains a suitable temperature environment, but also provides a cool shelter for delicate plants in the hot summer season, effectively preventing the potential damage to plants caused by excessive sunlight and ensuring the healthy growth of crops.

[0003] At present, with the development of modern agriculture, greenhouse planting technology is also constantly improving. In order to improve the automation level and efficiency of greenhouse management and reduce labor intensity, it is particularly important to develop an automatic opening and closing mechanism for sunshade nets. This mechanism can automatically adjust the opening and closing state of the sunshade net according to environmental parameters such as light intensity and temperature in the greenhouse to achieve precise environmental control. Although a variety of automatic opening and closing devices for sunshade nets have emerged on the market, these devices still have room for improvement in terms of the rationality of structural design, operational stability, and user convenience. In particular, the sunshade net is exposed to the complex and changeable greenhouse environment for a long time, and is easily affected by factors such as ultraviolet radiation, temperature and humidity changes, and has problems such as aging, breakage or deformation, which not only affects the shading effect, but also increases maintenance costs. In addition, there are inevitably sharp objects inside the greenhouse. These potential risk sources may accidentally scratch the sunshade net, resulting in the loss of shading function, and the replacement process is often cumbersome and time-consuming.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0029] Example:

[0030] See also Figure 1 , Figure 7 , Figure 8 , Fig. 9 A sunshade net automatic opening and closing mechanism comprises two mounting rods 1, one end of the two mounting rods 1 is bolted with an auxiliary rolling mechanism 2, and the other end is installed with a closing mechanism 3; the auxiliary rolling mechanism 2 comprises two bearing seats 21, a connecting rod 22, a driving motor 23 and a coupling 24; the closing mechanism 3 comprises two mounting seats 31, two rope collecting motors 32, two limit seats 33, two rope collecting wheels 34, two pull ropes 35 and two pull rings 36.

[0031] Among them, the two mounting rods 1 are made of high-strength, corrosion-resistant metal materials. The two mounting rods 1 are arranged in parallel and fixed on the greenhouse frame by bolts or other fastening methods; it is convenient to become the installation basis of other components.

[0032] Among them, the auxiliary rolling mechanism 2 is one of the components for rolling and unfolding the sunshade net 442, and its design is directly related to the operating efficiency and stability of the sunshade net 442. The bearing seat 21 is made of high-strength, wear-resistant metal material, and there are two of them, corresponding to one end of the two mounting rods 1 respectively. Each bearing seat 21 is provided with a mounting hole for fixing and connecting with the connecting plate bolts on the mounting rod 1. The connecting rod 22 is made of a metal material with certain rigidity and toughness, and its length is slightly larger than the distance between the two mounting rods 1 to ensure that both ends can be firmly installed in the bearing seat 21. The two ends of the connecting rod 22 are respectively processed with a connecting structure matching the inner wall of the bearing seat 21, such as a keyway or a threaded hole, so as to be fixedly connected with the bearing seat 21. The drive motor 23 uses a low-noise, high-efficiency DC or AC motor, and its fixed end is fixed to the side wall of the connecting plate at one end of the mounting rod 1 by bolts. The motor model and power need to be selected according to the area, weight and operation requirements of the sunshade net 442 to ensure sufficient driving force. The coupling 24 is a connecting component between the drive motor 23 and the connecting rod 22. The coupling 24 needs to have good elasticity, rigidity and wear resistance. The two ends are respectively processed with a connecting structure that matches the output end of the drive motor 23 and the inner end of the connecting rod 22, such as a flange or a clamping sleeve, so as to achieve a firm connection. During installation, it is necessary to ensure that the concentricity and axial clearance of the coupling 24 meet the design requirements to avoid vibration and noise during operation. When the drive motor 23 is started, its output end drives the connecting rod 22 to rotate through the coupling 24. Since the two ends of the connecting rod 22 are respectively fixedly connected to the two bearing seats 21, and the bearing seats 21 are fixed to the connecting plate on the mounting rod 1 by bolts, the rotation of the connecting rod 22 will drive the sunshade net 442 connected thereto to assist in the winding or unfolding action when opening and closing. Specifically, when the motor rotates forward, the sunshade net 442 is rolled onto the connecting rod 22; when the motor rotates reversely, the sunshade net 442 is released and unfolded to the specified position.

[0033] Among them, the closing mechanism 3 is a key part for controlling the opening and closing of the sunshade net 442, and its design needs to ensure the opening and closing action of the sunshade net 442. The mounting seat 31 is made of a sturdy and durable metal material, and there are two of them, corresponding to one end of the two mounting rods 1 respectively. The outer wall of the mounting seat 31 is firmly connected to the inner wall of the mounting rod 1 by welding to ensure the stability of the closing mechanism 3. The rope collecting motor 32 uses a small, efficient, low-noise DC motor, and there are two of them, which are fixedly installed on the surface of the two mounting seats 31 respectively. The output end of the rope collecting motor 32 directly passes through the side wall of the limit seat 33 and is fixedly connected to the inner wall of the rope collecting wheel 34 to drive the rotation of the rope collecting wheel 34. The limit seat 33 serves as a supporting component for the rope collecting motor 32 and the rope collecting wheel 34. The limit seat 33 is also made of a sturdy and durable metal material. Its bottom end is connected to one end of the inner wall of the cavity 412 in the guide mechanism 41 by bolts to ensure stability during the rope collecting process. The rope collecting wheel 34 is made of wear-resistant and corrosion-resistant materials, and its wheel groove matches the pull rope 35 to ensure that the pull rope can be smoothly wound and released. The inner wall of the rope collecting wheel 34 is fixedly connected to the output end of the rope collecting motor 32 so that the motor drives it to rotate. The pull rope 35 is made of high-strength, wear-resistant synthetic fiber material and has sufficient tensile strength and wear resistance. One end of the pull rope 35 is fixedly connected to the rope collecting wheel 34, and the other end is fixedly connected to the pull ring 36 to transmit the driving force of the rope collecting motor 32 to the limiting mechanism of the sunshade net quick release device 4. As a connecting component between the pull rope 35 and the sunshade net quick release device 4, the pull ring 36 needs to have a certain strength and toughness. The two pull rings 36 are respectively welded to the side walls of the sliding block I 421 and the sliding block II 431 so that under the drive of the rope collection motor 32, the sliding block I 421 and the sliding block II 431 are driven by the pull rope 35 to slide in the guide mechanism 41, thereby realizing the opening and closing action of the sunshade net 443.

[0034] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Fig. 9 , Fig.10, an automatic opening and closing mechanism for a sunshade net, a sunshade net quick-release device 4 is installed between two installation rods 1, and the sunshade net quick-release device 4 consists of a guiding mechanism 41, a limiting mechanism I 42, a limiting mechanism II 43 and a sunshade mechanism 44; the guiding mechanism 41 includes two sets of sliding grooves 411 and two cavities 412; the limiting mechanism I 42 includes a sliding block I 421, two clamping rods I 422, two semicircular balls I 423, two limiting steel balls I 424 and a micro motor 425; the limiting mechanism II 43 includes a sliding block II 431, two clamping rods II 432, two semicircular balls II 433, two limiting steel balls II 434, a sliding cavity 435, a spring 436, a plug-in column 437, a limiting ring 438 and a handle 439; the sunshade mechanism 44 includes a winding rod 441 and a sunshade net 442.

[0035] Among them, the guide mechanism 41 is used as the sliding block in the sunshade net quick release device 4, namely the sliding block Ⅰ421 of the limiting mechanism Ⅰ and the sliding block 431 of the limiting mechanism Ⅱ. For the sake of simplified description, they are uniformly referred to as the guiding and supporting components of the sliding blocks. The design needs to ensure that the sliding blocks can slide steadily and smoothly on the mounting rod 1. Sliding grooves 411 are respectively provided at the upper and lower ends of the two mounting rods 1, corresponding to the two limiting steel balls Ⅰ424 and the two limiting steel balls Ⅱ434 respectively; at the same time, the length of the sliding groove 411 should be long enough to accommodate the stability of the sunshade net 442 in the fully unfolded and retracted states. Two cavities 412 are respectively provided on the side walls of the two mounting rods 1. The positions of the cavities 412 correspond to the sliding grooves 411, but are located inside the side walls of the mounting rods 1. The function of the cavity 412 is to provide installation space for some components of the limiting mechanism including the limiting mechanism I and the limiting mechanism II, such as the sliding block I 421 and the sliding block II 431, and to allow these components to perform necessary movements during the opening and closing of the sunshade net 442. The cross-sectional shape and size of the cavity 412 should be determined according to the specific design of the limiting mechanism.

[0036] Among them, the limiting mechanism I42 is an important component of the sunshade net quick release device 4. Its design is to ensure that the sunshade net 442 can stably move along the predetermined track during the unfolding and folding process, and prevent accidental falling off or deviation. The sliding block I421 is made of high-strength and wear-resistant materials, and its outer wall is slidably connected to the inside of the cavity 412 in the guide mechanism 41 to achieve a smooth sliding action. The sliding block I421 has a through hole inside for installing the output end of the micro motor 425, and is connected to one end of the sunshade mechanism 44 by a fixed plug-in method. Two clamping rods I422 are welded to the upper and lower ends of the sliding block I421 respectively, and are arranged opposite to each other. The inner end of each clamping rod I422 has a semicircular ball I423, which fits tightly with the outer wall of the mounting rod 1 to play a positioning and supporting role. The design of the semicircular ball I423 can reduce the friction between the mounting rod 1 and increase the smoothness of sliding. Two limiting steel balls Ⅰ424 are respectively installed inside the two semicircular balls Ⅰ423 and maintain contact with the inside of the sliding groove 411. When the sliding block Ⅰ421 slides along the sliding groove 411, the limiting steel balls Ⅰ424 will roll or slide in the sliding groove 411, thereby ensuring that the sliding block Ⅰ421 always remains on the correct track, ensuring the stability of the limiting mechanism Ⅰ42. The micro motor 425 uses a small, efficient, low-noise DC motor as the micro motor 425, and its fixed end is connected to the outer end of the sliding block Ⅰ421 by a bolt. The output end of the micro motor 425 passes through the through hole of the sliding block Ⅰ421 and is fixedly connected to one end of the sunshade mechanism 44. When necessary, the micro motor 425 can drive the winding roller 441 to rotate.

[0037] Among them, the limiting mechanism II43 is another key component in the sunshade net quick release device 4, and its design is intended to provide a more stable limiting effect and convenient manual operation function. The sliding block II431 is also made of high-strength, wear-resistant materials, and its outer wall is slidably connected to the inside of the cavity 412 in the guide mechanism 41 to ensure that the sunshade net 442 can move smoothly during the opening and closing process. A sliding cavity 435 is provided inside the sliding block II431 for installing and fixing other components. Two clamping rods II432 are welded to the upper and lower ends of the sliding block II431 respectively, and are arranged opposite to each other. The inner end of each clamping rod II432 is equipped with a semicircular ball II433, which fits tightly with the outer wall of the mounting rod 1 to play a positioning and supporting role. The design of the semicircular ball II433 can reduce the friction between the mounting rod 1 and improve the smoothness of sliding. Two limiting steel balls II434 are respectively installed inside the two semicircular balls II433 and maintain contact with the inside of the sliding groove 411. When the sliding block Ⅱ431 slides along the sliding groove 411, the limiting steel ball Ⅱ434 will roll or slide in the sliding groove 411 to ensure that the sliding block Ⅱ431 always remains on the correct track. The sliding cavity 435 is opened inside the sliding block Ⅱ431 for installing components such as the plug-in column 437. The spring 436 is sleeved on the outer wall of the plug-in column 437, and the two ends are elastically fitted with the inner wall of the sliding cavity 435 and the opposite end of the limiting ring 438 respectively. This design enables the plug-in column 437 to move along the sliding cavity 435 under the action of external force, and return to the initial position through the elastic force of the spring 436 when there is no external force. The outer end of the plug-in column 437 is equipped with a handle 439 for the convenience of manual operation by the user. The inner ring of the limiting ring 438 is welded to the outer wall of the plug-in column 437 to play a role of fixing and limiting.

[0038] Among them, the sunshade mechanism 44 is the core part of the sunshade net quick release device 4, and its design is to achieve the purpose of sunshade. The winding rod 441 is the main part of the sunshade mechanism 44, and is made of light but strong material so as to maintain sufficient strength and stability when winding and unfolding the sunshade net 442. The two ends of the winding rod 441 are respectively designed to fit closely with the opposite ends of the sliding block I 421 and the sliding block II 431, so as to ensure that the winding rod 441 can move smoothly with the sliding block during the movement of the sunshade net 442. The output end of the micro motor 425 is firmly connected to one end of the winding rod 441 by a clamping connection. In this way, when the micro motor 425 is started, its rotational power can be directly transmitted to the winding rod 441, driving it to rotate and drive the sunshade net 442 to fold or unfold. As a part of the limit mechanism II 43, the plug-in column 437 is designed with a plug-in structure matching the other end of the winding rod 441 at its inner end. Ensure the stability of the winding rod 441. The other end of the sunshade net 442 is bonded to the surface of the connecting rod 22 by glue or other adhesives to fix the sunshade net when it is fully unfolded.

[0039] The working principle of the automatic opening and closing mechanism of the sunshade net is as follows: when the sunshade net 442 needs to be opened, first ensure that the sunshade net 442 is rolled up on the connecting rod 22, and the limiting mechanism I42 and the limiting mechanism II43 are close to the position of the connecting rod 22. The two rope-collecting motors 32 are started at the same time according to the control signal, driving the rope-collecting wheel 34 to rotate and wind the pull rope 35, and as the pull rope 35 is wound; at the same time, the driving motor 23 is started according to the control signal, driving the connecting rod 22 to rotate and release the sunshade net 442; the limiting mechanism I42 and the limiting mechanism II43 move toward the other end of the mounting rod 1 under the traction of the pull rope 35, and the sliding block slides inside the cavity 412 and moves the winding rod 441 with it, so that the sunshade net 442 is gradually unfolded and covers the area that needs shading. When the sunshade net needs to be retracted, the above steps can be reversed. When the sunshade net 442 needs to be replaced, the sunshade net 442 at the connecting rod 22 is cut with a cutter. The micro motor 425 starts according to the control signal and drives the winding roller 441 to rotate. When the winding roller 441 rotates counterclockwise, the sunshade net 442 is gradually retracted and recovered on the winding roller 441. Then, the plug-in column 437 is pulled by the handle 439, so that the spring 436 is compressed by the limit ring 438, and the inner end of the plug-in column 437 is separated from the winding roller 441, so that the user can replace the sunshade net 442 conveniently.

[0040] It should be noted that the specific models and specifications of the micro motor 425, the drive motor 23, and the rope collection motor 32 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0041] The power supply and principles of the micro motor 425, the drive motor 23, and the rope collecting motor 32 are clear to those skilled in the art and will not be described in detail here.

[0042] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application.
