DETAILED DESCRIPTION

[0027] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following briefly introduces the drawings required for use in the embodiments. Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0028] Please see Figures 1 to 10The present invention provides a sightseeing greenhouse 10, comprising a first greenhouse 111 and a second greenhouse 112 arranged front and back, and a greenhouse sunshade system connected to the first greenhouse 111 and the rear wall of the first greenhouse 111, and a rest area for tourists between the first greenhouse 111 and the second greenhouse 112; The greenhouse shading system includes a support assembly 12, a retractable assembly 13, a shading net 14, and a plurality of guide assemblies 15 and a pulley assembly 16; the support assembly 12 includes a front support mechanism 121 and a rear support mechanism 122, which are respectively mounted above the rear wall 1111 of the first greenhouse and the rear wall 1121 of the second greenhouse, and a plurality of guide assemblies 15 are respectively connected to the front support mechanism 121 and the rear support mechanism 122, and one end of the shading net 14 is fixed to the front support mechanism 121, and the other end is a free end, which is slidably mounted. On the guide assembly 15, multiple pulley assemblies 16 are fixedly mounted on the support assembly 12, and the retractable assembly 13 is fixedly mounted above the rear wall 1121 of the second greenhouse, and is fixedly connected to the free end of the sunshade net 14, and is used to cooperate with the pulley assembly 16 to retract or release the sunshade net 14 along the guide assembly 15 to above the rear wall 1111 of the first greenhouse, so as to provide shade for the first greenhouse 111 and the area between the first greenhouse 111 and the second greenhouse 112, providing a place for tourists to relax, entertain and rest.

[0029] In this embodiment, the sightseeing greenhouse 10 is particularly suitable for rural leisure tourism in the northwest region from spring to late autumn. The first greenhouse 111 and the second greenhouse 112 are arranged front and back, and there is a place for tourists to rest between the first greenhouse 111 and the second greenhouse 112. The greenhouse sunshade system is respectively set up above the back wall 1111 of the first greenhouse and the back wall 1121 of the second greenhouse. In this way, the greenhouse sunshade system is used to shade the first greenhouse 111 and the area between the first greenhouse 111 and the second greenhouse 112, which can not only provide tourists with plant display and fruit picking projects, but also provide tourists with a place for leisure, entertainment and rest. Secondly, the indoor temperature of the first greenhouse 111 can be effectively adjusted by adjusting the degree of opening of the sunshade net 14. The black sunshade net 14 blocks the sunlight to prevent the indoor temperature of the first greenhouse 111 from being too high. At the same time, the black sunshade net 14 will also absorb the radiant heat of the sunlight and hinder the radiant heat of the sunlight from diffusing to the first greenhouse 111. The sunshade net 14 is arranged above the first greenhouse 111 and has a gap of a predetermined distance from the first greenhouse 111, which can ensure that the radiant heat of sunlight absorbed by the black sunshade net 14 will not be transmitted to the interior of the first greenhouse 111, and the external air flow flows through the gap between the sunshade net 14 and the first greenhouse 111, which will also hinder the radiant heat absorbed by the black sunshade net 14 and part of the radiant heat of sunlight from reaching the interior of the first greenhouse 111, thereby effectively adjusting the indoor temperature of the first greenhouse 111; finally, the leisure and entertainment venue is arranged between the first greenhouse 111 and the second greenhouse 112, which improves the land utilization rate, and the greenhouse shading system is erected above the back wall 1111 of the first greenhouse and the back wall 1121 of the second greenhouse, with sufficient space. Compared with being set on the ground, it will not make tourists feel depressed due to the low height of the space, and it is also convenient for air circulation to improve the comfort of tourists.

[0030] Furthermore, the front support mechanism 121 and the rear support mechanism 122 each include a top cross bar 1211, a middle cross bar 1212 and a plurality of support vertical bars 1213. The plurality of support vertical bars 1213 are rotatably installed at one end at equal intervals above the rear wall 1111 of the first greenhouse and the rear wall 1121 of the second greenhouse, and the other end is a free end. The top cross bar 1211 is fixedly installed at the free end of the support vertical bar 1213 and is perpendicular to the support vertical bar 1213. Guide assembly mounting holes 12111 are arranged at equal intervals on the top cross bar 1211. The middle cross bar 1212 is fixedly installed in the middle of the support vertical bar 1213 and is parallel to the top cross bar 1211. A plurality of guide assemblies 15 are respectively connected to the top cross bars 1211 in the front support mechanism 121 and the rear support mechanism 122 through the guide assembly mounting holes 12111.

[0031] Furthermore, the guide assembly 15 includes a fixed screw 151 and a guide wire rope 152. Both ends of the guide wire rope 152 are connected to the fixed screws 151. The fixed screws 151 are respectively threadedly matched with the guide assembly mounting holes 12111 to connect the top cross bars 1211 in the front support mechanism 121 and the rear support mechanism 122.

[0032] In this embodiment, through the threaded cooperation between the fixed screw 151 and the guide assembly mounting hole 12111, not only is it possible to connect the front support mechanism 121 with the top cross bar 1211 of the rear support mechanism 122 by using the guide wire rope 152, but the tension of the guide wire rope 152 can also be accurately adjusted by rotating the fixed screw 151.

[0033] Furthermore, the front support mechanism 121 and the rear support mechanism 122 also include a plurality of tensioning mechanisms 1214, which are arranged at equal intervals, and one end of each is rotatably mounted on the middle cross bar 1212, and the other end is rotatably mounted on the first greenhouse shed 111 and the second greenhouse shed 112, so as to adjust the tensioning degree of the guide wire rope 152 through the tensioning mechanism 1214.

[0034] In this embodiment, the tensioning mechanism 1214 is provided to preliminarily adjust the tensioning degree of the guide wire rope 152. Compared with the adjustment of the above-mentioned fixed screw 151, the adjustment range of the tensioning mechanism 1214 is larger.

[0035] It is worth noting that in this embodiment, the tensioning mechanism 1214 and multiple supporting vertical rods 1213 are respectively connected to the cross bars and steel beams in the first greenhouse 111 and the second greenhouse 112 through pins. The tensioning mechanism 1214, the supporting vertical rods 1213 and the steel beams form a triangular structure, which not only improves the stability and strength of the support assembly 12, but also facilitates installation and disassembly.

[0036] Furthermore, the retractable assembly 13 includes a rotating mechanism 131, a retractable wire rope 132 and a rotating rod 133. The rotating mechanism 131 includes a driving module 1311 and a deceleration module 1312. The driving module 1311 and the deceleration module 1312 are both fixedly mounted on the top of the rear wall of the second greenhouse 112. The driving module 1311 and the deceleration module 1312 are connected by transmission. The retractable wire rope 132 passes around the pulley assembly 16, and both ends are fixed and wound on the rotating rod 133 in opposite directions. One end of the rotating rod 133 is threadedly connected to the rotating mechanism 131, and the other end is a free end. The rotating mechanism 131 is used to drive the rotating rod 133 to rotate while moving the rotating rod 133 axially, and orderly wind or release the wire rope to avoid mixed wear between the retractable wire ropes 132.

[0037] Furthermore, the rotating rod 133 includes a winding rod and a threaded rod 1332 . The winding rod is coaxially connected to the threaded rod 1332 . The winding rod is provided with a plurality of paired wire rope fixing holes 13311 for fixing and installing the wire rope 132 . The threaded rod 1332 is threadedly connected to the rotating mechanism 131 .

[0038] In this embodiment, when the rotating mechanism 131 drives the threaded rod 1332 to rotate, the threads of the threaded rod 1332 cooperate with the threads of the rotating mechanism 131, so that the threaded rod 1332 moves axially and drives the winding rod to rotate and reel in the wire rope 132 while moving, ensuring that the wire rope 132 will not be worn out during the retraction process, thereby extending the service life of the sunshade system.

[0039] In an embodiment, the driving module 1311 can be an electric motor, which realizes the winding and releasing of the retractable wire rope 132 by controlling the forward and reverse rotation of the motor. In order to ensure the stable operation of the driving module 1311, a limit switch can also be set to prevent mechanical damage caused by excessive winding or releasing of the retractable wire rope 132.

[0040] Furthermore, the pulley assembly 16 includes a first fixed pulley 161 and two second fixed pulleys 162. The first fixed pulley 161 is fixedly mounted on the top cross bar 1211 of the rear support mechanism 122, and the two second fixed pulleys 162 are both fixedly mounted on the top cross bar 1211 of the front support mechanism 121. The first fixed pulley 161 and the second fixed pulley 162 are at the same height. The retractable wire rope 132 is wound around the first fixed pulley 161, one end of which passes around the second fixed pulley 162, is coiled on the winding rod for several turns, and is fixedly mounted on the winding rod through the retractable wire rope fixing hole 13311, and the other end of which passes around another second fixed pulley 162, is coiled in reverse on the winding rod for several turns, and is fixedly mounted on the winding rod through the retractable wire rope fixing hole 13311.

[0041] In this embodiment, one end is connected to the rotating mechanism 131 through a thread, and the other end is a rotating rod 133 as a free end, which passes through the first and second fixed pulleys 162 through the retractable wire rope 132 and is fixedly mounted on the rotating rod 133 at both ends. With the weight of the rotating rod 133 itself, the elastic tensioning of the retractable wire rope 132 can be achieved.

[0042] It is worth noting that the winding directions of the two ends of the retractable wire rope 132 must be opposite to ensure that during the retractable process, one end of the retractable wire rope 132 is wound onto the reel and the other end is released from the reel.

[0043] Furthermore, the retractable steel wire rope 132 is also fixedly connected to the free end of the sunshade net 14 to pull the sunshade net 14 and move it along the guide steel wire rope 152, thereby realizing the unfolding and folding of the sunshade net 14.

[0044] In this embodiment, several series of slip rings 141 are arranged in parallel on the sunshade net 14 to sleeve the sunshade net 14 on the guide wire rope 152. The sunshade net 14 is installed on the guide wire rope 152 through the several series of slip rings 141, so that the sunshade net 14 can be smoother when unfolding and folding, and the friction damage to the sunshade net 14 is reduced. The use of the slip ring 141 not only improves the service life of the sunshade net 14, but also ensures the stability of the sunshade net 14 during movement.

[0045] It is worth noting that the material of the slip ring 141 is usually corrosion-resistant and wear-resistant to adapt to the humid and dusty environment in the greenhouse. In practical applications, the spacing of the slip ring 141 can be flexibly adjusted according to the width of the shade net 14 and the length of the greenhouse 11 to achieve the best shading effect and use efficiency.

[0046] In another embodiment, the sunshade net 14 can also be directly connected to the retractable steel wire rope 132 without using the slip ring 141, thereby simplifying the structure and reducing maintenance costs. In this case, both ends of the sunshade net 14 are directly connected to the retractable steel wire rope 132, and the expansion and contraction of the sunshade net 14 is controlled by the extension and contraction of the retractable steel wire rope 132. In order to ensure the stability of the sunshade net 14 during movement, a reinforcement belt can be set at the edge of the sunshade net 14. The connection between the reinforcement belt and the retractable steel wire rope 132 is more secure, and can also withstand greater tension.

[0047] Furthermore, the area between the first greenhouse 111 and the second greenhouse 112 is planted with lawns and is provided with seats for tourists to rest.

[0048] In this embodiment, the lawn planted in the area between the first greenhouse 111 and the second greenhouse 112 can not only provide a place for tourists to rest, but also allow the soil to retain moisture and reduce moisture evaporation from the soil.

[0049] Of course, other facilities such as fountains, fans, etc. can be added in the area between the first greenhouse 111 and the second greenhouse 112 to enhance the visitors' experience.

[0050] Furthermore, the sightseeing greenhouse 10 also includes a lighting and temperature control component, which includes a light sensor and a temperature sensor. The temperature sensor is arranged in the first greenhouse 111 and the second greenhouse 112 to detect the temperature in the greenhouse. The light sensors are arranged at equal intervals on the side walls of the greenhouse to detect the light intensity at different positions on the horizontal plane in the greenhouse. The light sensor and the temperature sensor are both electrically connected to the driving module 1311 to adjust the shading degree of the shading net 14 above the greenhouse according to the collected light and temperature information in the greenhouse.

[0051] In this embodiment, the driving module 1311 automatically controls the folding and unfolding of the sunshade net 14 according to the data provided by the light sensor and the temperature sensor to achieve ideal light and temperature conditions. When it is detected that the light intensity in the greenhouse exceeds the preset value, the driving module 1311 will automatically drive the rotating mechanism 131 to unfold the sunshade net 14, reduce direct sunlight, and reduce the temperature in the greenhouse; conversely, when the light intensity is lower than the preset value, the driving module 1311 will drive the rotating mechanism 131 to retract the sunshade net 14 to increase light. Similarly, if the temperature sensor in the greenhouse detects that the temperature is too high, the driving module 1311 will also adjust the position of the sunshade net 14 accordingly to reduce the temperature. Through this adjustment mechanism, the light and temperature in the greenhouse can be effectively maintained within a range suitable for plant growth, thereby improving the yield and quality of crops.

[0052] Of course, the greenhouse shading system in this embodiment can also be equipped with a user interface, through which the user can manually adjust the position of the shading net 14 and set the thresholds of light and temperature. The user interface can be a touch screen or a button control panel, which is convenient for users to operate according to actual needs and experience. At the same time, the system also has a fault diagnosis function. When the system detects an abnormal situation, such as the shading net 14 is stuck or the sensor fails, the system will issue a warning through the user interface and provide corresponding fault information so that the user can perform maintenance and repairs in time.

[0053] When the present invention is implemented, the staff needs to start the driving module 1311, and then the driving module 1311 rotates, and the rotating mechanism 131 starts to work, driving the threaded rod 1332 to rotate, and then the winding rod rotates and moves axially, and the retractable wire rope 132 is wound or released accordingly, thereby controlling the sunshade net 14 to unfold or retract along the guide wire rope 152. This not only provides tourists with plant displays and fruit picking projects, but also provides tourists with a place for leisure, entertainment and rest, while avoiding the problem of the wire rope breaking due to mixed wear and tear, and the equipment being damaged and unusable.

[0054] The modules or units in the device of the embodiment of the present invention can be combined, divided and deleted according to actual needs. The above disclosure is only the preferred embodiment of the present invention, and of course it cannot be used to limit the scope of the rights of the present invention. Those skilled in the art can understand that all or part of the processes of the above embodiment are implemented, and the equivalent changes made according to the claims of the present invention still fall within the scope of the present invention.
