Description

Technical Field

[0001] This utility model relates to the field of agricultural engineering technology, specifically to a sun protection and anti-fall device for a greenhouse insulation blanket. Background Technology

[0002] As the core infrastructure for facility vegetable production in northern my country, the greenhouse, with its efficient use of light and environmental regulation capabilities, can create suitable temperature and light conditions for vegetable growth in the low-temperature winter environment, effectively ensuring a stable supply of vegetables in the winter and spring seasons in the north. It is a key piece of equipment for promoting the development of facility agriculture in northern China and improving agricultural production efficiency, and plays an irreplaceable role in ensuring regional vegetable security and increasing farmers' income.

[0003] However, in actual operation of solar greenhouses, there are significant problems with the management of insulation blankets, which are closely related to the safe production of vegetables: On the one hand, in winter, due to the lack of necessary protective facilities on the back slope, insulation blankets often fall over the back slope of the greenhouse and onto the ground behind the back wall when not properly operated and managed. If not repaired in time, the temperature inside the greenhouse will drop sharply, and vegetables will be susceptible to frost damage or chilling injury, resulting in irreparable economic losses. Moreover, the repair process requires a lot of manpower and resources, which increases production costs.

[0004] Furthermore, to avoid occupying planting space during the summer, insulation blankets are often rolled up to the top of the greenhouse for overwintering. Under the combined effects of high temperatures, strong sunlight, and rain erosion, the insulation blankets are prone to aging and damage, significantly shortening their lifespan. Frequent replacement of insulation blankets further increases the economic burden on growers. These problems seriously restrict the efficiency and stability of vegetable production in solar greenhouses. Therefore, it is urgent to design a sun protection and anti-fall device for solar greenhouse insulation blankets to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a sun protection and anti-fall device for greenhouse insulation blankets, so as to solve the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A solar greenhouse heat insulation blanket sun protection and anti-fall device includes a greenhouse body, a protective net assembly is provided on the top of the greenhouse body, the protective net assembly is integrally welded to the frame on the top of the greenhouse body, a number of support rods are provided on the outer wall of the frame, a number of connecting rods are provided between the support rods, and a covering cloth is provided on the outer wall of the support rods.

[0008] A drive assembly is provided on one side of the shed. The drive assembly includes a roller shutter machine. The output shaft of the roller shutter machine is keyed to a shaft rod, and an insulation blanket is fitted onto the outer wall of the shaft rod.

[0009] Preferably, a push-pull rod is welded to the bottom of the roller shutter machine, a support rod is provided at one end of the push-pull rod, and a rubber wheel is bolted to the bottom of the support rod.

[0010] Preferably, a blocking block and a collision switch are respectively provided on both sides of the shed, and the blocking block is aligned with the axis of the rubber wheel.

[0011] Preferably, the covering fabric includes a military green rainproof and sunproof tarpaulin and a strip-shaped sunproof and rainproof curtain. The military green rainproof and sunproof tarpaulin covers the top frame composed of support rods and connecting rods, and the strip-shaped sunproof and rainproof curtain is suspended at the front end of the frame.

[0012] Preferably, the push-pull rod is fully welded to the bottom of the roller shutter machine, and the push-pull rod and the support rod are detachably connected by a flange. The length of the support rod is adapted to the height of the canopy to ensure that the rubber wheel can stably contact the ground or the canopy support surface.

[0013] Preferably, the outer wall of the rubber wheel is covered with an anti-slip rubber layer, and the surface of the rubber layer is provided with diamond-shaped anti-slip patterns. The diameter of the rubber wheel is adapted to the height of the blocking block to ensure that the rubber wheel can be accurately limited when it contacts the blocking block.

[0014] Preferably, the collision switch is a stroke-type collision sensor. The collision switch is fixed to the side of the shed near the protective net assembly by a bracket. The sensing end of the collision switch faces the direction of movement of the insulation blanket. The collision switch is electrically connected to the control circuit of the roller shutter machine. When the collision switch senses contact between the insulation blanket or the support rod, it can immediately cut off the power supply of the roller shutter machine.

[0015] In the above technical solution, the beneficial effects of the sun protection and anti-fall device for the heat insulation blanket of the solar greenhouse provided by this utility model are as follows:

[0016] (1) By setting up a protective net assembly on the top of the shed, and combining it with military green rainproof and sunproof tarpaulin and strip curtain, it can effectively block the erosion of the thermal insulation blanket by summer high temperature, strong light and rain, prevent the thermal insulation blanket from aging faster due to sun and rain, significantly extend its service life, reduce the frequency of replacement of thermal insulation blanket and cost investment, and reduce production expenditure.

[0017] (2) By using the limiting effect of the blocking block on the rubber wheel, combined with the linkage design of the collision switch and the control circuit of the rolling curtain machine, the insulation blanket can be accurately prevented from slipping to the ground of the back wall due to improper operation, thus avoiding freezing or cold damage to vegetables. At the same time, in winter, it can guide rain and snow to slide down the greenhouse film, preventing the greenhouse from collapsing due to heavy snow pressure, and comprehensively ensuring the safe production of vegetables and the safety of the facilities in the solar greenhouse.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-4 As shown in the figure, the present invention provides a solar greenhouse heat insulation blanket sun protection and anti-fall device, including a greenhouse body 1, a protective net assembly 2 on the top of the greenhouse body 1, the protective net assembly 2 being integrally welded to the greenhouse frame 21 on the top of the greenhouse body 1, a plurality of support rods 22 being provided on the outer wall of the greenhouse frame 21, a plurality of connecting rods 23 being provided between the support rods 22, and a covering cloth 24 being provided on the outer wall of the support rods 22; a drive assembly 3 being provided on one side of the greenhouse body 1, the drive assembly 3 including a roller shutter machine 31, the output shaft of the roller shutter machine 31 being keyed to a shaft rod, and a heat insulation blanket 32 ​​being sleeved on the outer wall of the shaft rod.

[0026] In this embodiment, the greenhouse 1 serves as the main support of the device. It is constructed with a steel frame structure and has an arc-shaped sloping top to meet the needs of northern solar greenhouses for winter light gathering and summer ventilation. The greenhouse 1 has reserved installation areas for drive components 3 and connection areas for protective net components 2 on both sides. The side closer to the operating room is specifically used to fix the rolling shutter machine 31 to ensure convenient operation of the equipment without occupying planting space.

[0027] The top of the shed 1 is equipped with a protective net assembly 2. The protective net assembly 2 is integrally welded to the shed frame 21 on the top of the shed 1. The shed frame 21 is the core skeleton of the protective net assembly 2. It is made of the same steel as the steel frame of the shed 1 and is integrally welded to the arc-shaped steel frame on the top of the shed 1 through a full welding process to ensure the overall load-bearing capacity and resist winter snow accumulation and summer strong wind load.

[0028] The outer wall of the shed 21 is provided with several support rods 22. The support rods 22 are made of galvanized stainless steel pipe with an inner diameter of 1.0cm and a wall thickness of 3.9mm. They are bent at a 2 / 5 π arc, consistent with the arc of the top of the shed 1, and evenly distributed along the length of the shed 1. The spacing between adjacent support rods 22 is strictly controlled to be 2.0m.

[0029] Several connecting rods 23 are set between the support rods 22. The connecting rods 23 are stainless steel tubes with an inner diameter of 0.3mm. They are divided into two layers: horizontal and vertical. The horizontal connecting rods 23 connect the top and bottom of adjacent support rods 22. The vertical connecting rods 23 are set along the width of the shed body 1, with one rod every 1.5m. They are connected to the support rods 22 by welding and bolts to form a stable frame with a grid density of 2.0m×1.5m, preventing the frame from deforming and causing the covering cloth 24 to fall off.

[0030] The outer wall of the support rod 22 is provided with a cover cloth 24. The cover cloth 24 consists of two parts: a military green rainproof and sunproof cloth and a strip-shaped sunproof and rainproof cloth curtain. The military green rainproof and sunproof cloth is sealed to the edge of the top frame formed by the support rod 22 and the connecting rod 23 using a high-frequency heat sealing process. The heat sealing width is not less than 3cm to ensure that rainwater cannot penetrate.

[0031] The strip-shaped sunshade and rainproof curtain is detachably connected to the horizontal connecting rod 23 at the front of the frame using nylon hook-and-loop fasteners. The length of the curtain is adapted to the height of the frame, and the distance between the bottom and the greenhouse film is precisely controlled at 15cm. This avoids damage caused by friction between the curtain and the greenhouse film, blocks direct sunlight from the side, and does not affect the light transmittance of the greenhouse film.

[0032] A drive assembly 3 is provided on one side of the shed body 1. The drive assembly 3 includes a roller shutter machine 31. A connecting seat is provided on the outer wall of the roller shutter machine 31. The connecting seat is bolted to the push-pull rod 4. The output shaft of the roller shutter machine 31 is keyed to a shaft rod. An insulation blanket 32 ​​is sleeved on the outer wall of the shaft rod.

[0033] Specifically, a push-pull rod 4 is welded to the bottom of the roller shutter machine 31. The push-pull rod 4 is a solid round steel with a diameter of not less than 12mm. It is vertically welded to the shell at the bottom of the roller shutter machine 31 through a full welding process. The welded surface completely covers the end of the push-pull rod 4 to ensure stable transmission of pulling force.

[0034] One end of the push-pull rod 4 is provided with a support rod 2 5, and the end of the push-pull rod 4 away from the roller shutter machine 31 is provided with a flange. Bolt holes are opened on the flange, which is connected to the flange at the top of the support rod 2 5 by high-strength bolts. Rubber gaskets are installed between the flanges to reduce vibration and noise, and at the same time facilitate disassembly and maintenance in the future.

[0035] The bottom of the support rod 2 5 is bolted with a rubber wheel 6. The support rod 2 5 is made of seamless steel pipe, and its length is precisely calculated according to the height of the shed 1 to ensure that the rubber wheel 6 can stably contact the support surfaces on both sides of the shed 1 after installation. The rubber wheel 6 is connected to the bottom of the support rod 2 5 through a bearing. The outer wall of the rubber wheel 6 is wrapped with an anti-slip rubber layer, and the surface of the rubber layer is pressed with diamond anti-slip texture to enhance the friction with the support surface.

[0036] Specifically, the two sides of the shed body 1 are respectively equipped with a blocking block 7 and a collision switch 8. The blocking block 7 is on the same axis as the rubber wheel 6. The diameter of the rubber wheel 6 matches the height of the blocking block 7. When the rubber wheel 6 contacts the blocking block 7, its wheel center height is flush with the top of the blocking block 7 to achieve precise positioning. The blocking block 7 is made of concrete with a rectangular cross section and its height is the same as the diameter of the rubber wheel 6. It is set at the end position of the movement trajectory of the rubber wheel 6 along the length of the shed body 1.

[0037] The collision switch 8 uses a stroke-type collision sensor, which is fixed to the steel frame of the shed 1 near the protective net assembly 2 by an L-shaped bracket. The height of the bracket is flush with the top of the insulation blanket 32. The sensing end of the collision switch 8 faces the direction of movement of the insulation blanket 32, and the distance between the sensing end and the insulation blanket 32 ​​is controlled to be 5-8cm. The collision switch 8 is connected in series with the control circuit of the roller shutter machine 31 through a wire. The wire is protected by a conduit to avoid aging of the line due to sun and rain.

[0038] Specifically, the covering cloth 24 includes a military green rainproof and sunproof tarpaulin and a strip sunproof and rainproof curtain. The military green rainproof and sunproof tarpaulin covers the top frame formed by the support rod 22 and the connecting rod 23, and the strip sunproof and rainproof curtain is suspended at the front end of the frame.

[0039] Specifically, the push-pull rod 4 is fully welded to the bottom of the roller shutter machine 31, and the push-pull rod 4 is detachably connected to the support rod 2 via a flange. The length of the support rod 2 5 is adapted to the height of the canopy 1 to ensure that the rubber wheel 6 can stably contact the ground or the canopy support surface.

[0040] Specifically, the outer wall of the rubber wheel 6 is covered with an anti-slip rubber layer, and the surface of the rubber layer is provided with diamond-shaped anti-slip patterns. The diameter of the rubber wheel 6 is adapted to the height of the blocking block 7 to ensure that the rubber wheel 6 can be accurately limited when it comes into contact with the blocking block 7.

[0041] Specifically, the collision switch 8 adopts a stroke-type collision sensor. The collision switch 8 is fixed to the side of the canopy 1 near the protective net assembly 2 by a bracket. The sensing end of the collision switch 8 faces the direction of movement of the insulation blanket 32. The collision switch 8 is electrically connected to the control circuit of the roller shutter machine 31. When the collision switch 8 senses contact between the insulation blanket 32 ​​or the support rod 22, it can immediately cut off the power supply of the roller shutter machine 31.

[0042] Working steps: 1. According to the outside temperature and light conditions, start the control switch of the roller shutter machine 31, so that the output shaft of the roller shutter machine 31 drives the shaft rod to rotate in the opposite direction, and slowly unfold the insulation blanket 32 ​​from the protective net assembly 2 downwards.

[0043] 2. When the outside temperature rises or when lighting is needed, start the roller shutter machine 31 to run in the forward direction, and the shaft will drive the insulation blanket 32 ​​to be retracted towards the protective net assembly 2 at the top of the shed body 1;

[0044] 3. During the movement of the thermal insulation blanket 32, the strip-shaped sun-proof and rain-proof curtain at the front end of the protective net assembly 2 is pushed open, and the operation continues until the thermal insulation blanket 32 ​​is completely inside the protective net assembly 2.

[0045] IV. When the thermal blanket 32 ​​is not needed in summer, completely retract the thermal blanket 32 ​​into the protective net assembly 2 and check whether the military green rainproof and sunproof tarpaulin of the covering cloth 24 completely covers the thermal blanket 32.

[0046] 5. Check whether the strip-shaped sun and rain protection curtain hangs down naturally to ensure that the thermal insulation blanket 32 ​​is isolated from the outside high temperature, strong light and rain.

[0047] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
