Description

Technical Field

[0001] The utility model relates to the technical field of construction instruments and equipment, and particularly relates to an automatically telescopic greenhouse shed. Background Art

[0002] The greenhouse shed, having the effects of light transmission and heat preservation (heating), is widely used for cultivating non-seasonal crop varieties. Its main function is to adjust the temperature inside the shed and provide a suitable temperature and humidity for the crops. The traditional all-enclosed integrated greenhouse shed with a film and a barrel-shaped structure usually needs to be mechanically controlled for temperature and humidity to control the overall temperature state inside it. It cannot adjust the temperature through the opening and closing state of its own shed body. And when it comes to some crops that are not suitable for being cultivated in the greenhouse throughout the whole process, it needs to switch to the natural environment temperature. The greenhouse cannot be conveniently opened and closed, and cannot imitate the natural growth climate conditions. Therefore, its applicability is poor and it cannot meet the usage requirements of greenhouses with more diverse temperature control.

[0003] To achieve the above object, the utility model provides an automatically telescopic greenhouse shed, which can solve the problems put forward in the above background art. Content of the Utility Model

[0021] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0022] When the temperature is relatively low or the temperature needs to be raised inside the shed, the film around the greenhouse barrel-shaped steel frame group is unfolded through the side electric film roller and the end face electric film roller. At the same time, the retractable steel frame shed pole at the top and the film on the pole are unfolded together. The gravity hanging edge of the longitudinal side of the top film can lap and seal the surroundings, thus forming a relatively airtight space that can both transmit light and keep warm. On the contrary, after the film and the shed frame are all retracted and opened, the space inside the shed can become a natural space, which helps the crops to receive light and ventilate, enabling the greenhouse shed to meet various lighting requirements, without the need to disassemble and assemble the greenhouse shed according to the season, being able to adapt to the all-year climate adaptation requirements of multiple regions, and being able to adjust the internal temperature through the change of the shed body itself, reducing the use of temperature control equipment and having a more extensive application;

[0023] Through the cooperation of the clamping point seat and the clamping block, this device can have various opening and closing methods and heat dissipation and temperature increase methods between the shed frame and the film. For example: the simulated natural method with the film around and at the top fully open, the greenhouse airtight heat preservation method with full closure, the method of improving gas circulation with some parts of the film open in the area, and the method of controlling heat dissipation with a small area of the film open; greatly improving the effect of temperature improvement in the greenhouse shed, being able to adapt to the temperature requirements of different seasons, and at the same time having a more extensive application method, being able to better serve the needs with higher requirements for natural control of temperature and humidity in the greenhouse shed such as scientific research;

[0024] In addition, through the overall telescoping of this device, the need for lapping and disassembly and assembly can be reduced. At the same time, through improving the adjustment of heat dissipation and heat preservation, the overall lapping work of the greenhouse shed can be reduced, saving a large amount of manpower and material resources, and having a great effect on improving economic benefits.

[0039] The film 2 further includes a side film 208 and an end face film 209. The side film 208 is arranged on both sides of the arrangement direction of the shed frame 1, and the end face film 209 is arranged at both ends of the arrangement direction of the shed frame 1.

[0040] The lateral film winding group 102 includes a side electric film winder 112 and an end face electric film winder 113. The winding end of the side electric film winder 112 is connected to the side film 208, the winding end of the end face electric film winder 113 is connected to the end face film 209, and vertical edges 207 are provided on the sides of the film 2.

[0041] Please refer to Figures 1-3 , both ends of the top surface film 210 are provided with a starting end shaping piece 201 and a pushing end shaping piece 202. Blocks 203 are provided at the tops of the starting end shaping pieces 201, and the top film winding group 101 is connected to the blocks 203 through the clamping point seat 109 fixed to its upper part;

[0042] The steel frame shed pole 104 at the fixed end is fixed to the starting end shaping piece 201, and the steel frame shed pole 104 at the movable end is fixed to the pushing end shaping piece 202;

[0043] The anti-disengagement track 106 includes a main guiding track and a side guiding track. Side piles 206 are provided at both bottom ends of the starting end shaping piece 201 and the pushing end shaping piece 202. The side piles 206 move in the side guiding track. A wire reel group 204 is provided at one end of the anti-disengagement track 106 at the fixed end, and a traction wire 205 is provided at the other end of the wire reel group 204. The traction wire 205 passes through and moves between the two wire reel groups 204 and is fixed to the side pile 206 at the movable end at one end;

[0044] Multiple clamping point seats 109 are controlled to open and close independently.

[0045] One embodiment of the present invention is as follows: Figure 3 , Figure 4 :

[0046] The film 2 on the four sides and the top is fully open to simulate nature: that is, the locking effect of all the card point seats 109 is released, and the side electric film roll 112 and the end electric film roll 113 are driven to recycle the film 2 around the barrel-shaped steel frame group 103, so that the four sides of the scaffolding 1 can be naturally ventilated. At this time, the following can be done: Figure 1 , Figure 2 The installation position of the end face electric film roller 113 shown in the figure rolls up the end face film 209, and the upward rolling method can be conveniently used in conjunction with the vertical edge 207 for daily use by personnel entering and exiting the greenhouse. The side electric film roller 112 moves upward by the winding rotation force in conjunction with the vertical edge 207 for lifting, which is beneficial to the ground blocking in the normal state. The fully open natural top space opening method has two methods. One is that when the card point seat 109 is not in the working state, one side of the push-out end shaping piece 202 is pulled back by means of the take-up wheel group 204, so that the block 203 on the push-out end shaping piece 202 is disengaged from the card point seat 109 on the top of the steel frame shed pole 104 extending to the farthest end, so that the telescopic cooperation group 108 is not working. However, the upper space can still be opened; another method is to drive the telescopic matching group 108 so that the upper card seat 109 of the steel frame shed pole 104 extending to the farthest end drives the bottom card block 203 of the pushing end shaping piece 202 to follow the shed 1 to be retracted, and the traction line 205 can be selected as an elastic rope. The initial state of this process is that one end of the starting end shaping piece 201 is always fixed to the card seat 109 above the steel frame shed pole 104 at the static end, and the card block 203 at the pushing end shaping end is fixed to the card seat 109 on the upper part of the steel frame shed pole 104 extending to the far end of the telescopic matching group 108. This method is the most conventional method of retracting and releasing the top film roll group 101 in the utility model, and it can still meet the needs of simulating the open greenhouse shed in nature.

[0047] Another embodiment of the present utility model is a fully enclosed greenhouse airtight heat preservation method. The requirement for a fully enclosed greenhouse is to close the film 2 in all directions. Contrary to the previous embodiment, the side electric film winder 112 and the end face electric film winder 113 are both for the deployed and wound film 2. The bottom surface of the end face is closely attached through the vertical edge 207. The end face film 209 and the surrounding barrel-shaped steel frame group 103 can be fixedly attached in various ways, such as bar locking, Velcro attachment, etc. The two sides of the side film 208 and the barrel-shaped steel frame group 103 can also be edge-attached in the above ways. Different from this, the bottom of the telescopic fitting group 108 has a side electric film winder 112 and a film winding rod 114 for bottom pressing, and a fully enclosed greenhouse effect can be achieved by simply manually embedding or fixing the edge. In addition, the space at the top is closed in the same initial state as the second method in the above embodiment, that is, when the clamping seats 109 at the head and tail are both locked, through the driving effect of the telescopic fitting group 108, the end of the pushing end shaping piece 202 is driven to move to the other end edge, and the movement states of both sides are started and stopped through the synchronous driving device.

[0048] Please refer specifically to Figure 1 、 Figure 2 , one end of the anti-drop track 106 is provided with a synchronous driver 107, and the synchronous driver 107 is connected to one end of the top film winding group 101;

[0049] Both ends of the top film winding group 101 are provided with guide wheels 105, and the guide wheels 105 are matched with the anti-drop track 106;

[0050] The steel frame shed rod 104 includes a double-track movable groove 111. Adjacent two steel frame shed rods 104 are connected to the telescopic fitting group 108. The telescopic fitting group 108 includes two mutually connected movable rods 110, and both ends of the movable rod 110 are rotatably connected in the double-track movable groove 111.

[0051] Please refer specifically to Figure 1 、 Figure 2 , one end of the side electric film winder 112 is provided with a film winding rod 114, the film winding rod 114 is connected to the bottom edge of the side film 208, and the side electric film winder 112 is slidably connected to the barrel-shaped steel frame group 103;

[0052] The end face electric film winder 113 is fixed at both ends of the top of the barrel-shaped steel frame group 103. The winding end of the side electric film winder 112 is fixed to the starting edge of the end face film 209. The end face film 209, the side film 208 and the barrel-shaped steel frame group 103 can be detachably fixed.

[0053] Another embodiment of the present utility model is to improve the gas flow mode of the thin film 2 in the open area. This mode can be applied to the state of strong convective weather with high wind speed, that is, under the fully enclosed state, by controlling the energized working state of one or more clamping seat 109 at the farthest end, and cooperating with the opening and closing wire winding wheel set 204 to drive the thin film 2 to contract, so that the clamping block 203 under the pushing end shaping piece 202 is connected to the energized clamping seat 109 on the steel frame shed pole 104 at the farthest end, opening a part of the top space of the energized clamping seat 109 area, making the clamping block 203 fixed to the farthest clamping seat 109 without a closed effect. In this state, when there is strong convective wind weather, the air inlet caused by the poor airtightness of the greenhouse shed can be discharged through the open area, which can play a guiding role in the air flow direction in the shed, guiding the chaotic air inlets around it to the high flow rate at the top and then taking it out of the shed, avoiding the loss of greenhouse shed equipment and planted crops caused by the strong wind pressure rolled up due to strong convective weather, and improving the ability of the greenhouse shed to resist natural disasters.

[0054] Another embodiment of the present utility model is the control heat dissipation method of opening the thin film 2 in a small range: opening a small range is a method suitable for scientific research temperature control and the experimental greenhouse shed requirements of zoning temperature control. It is the same as the previous embodiment, that is, opening the top thin film 2 space on one side to obtain direct sunlight and heat dissipation in the shed, which can form a stepped temperature difference from one side to the other side. Installing equipment for zoning detection can quickly obtain the influence of temperature, humidity and other external environments on the growth of crops in the shed. This method further expands the application effect of this telescopic greenhouse shed.

[0055] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", "connection" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0056] The above content is only an example and explanation of the structure of the present utility model. Those skilled in the art of this technology make various modifications or supplements or use similar methods to replace the specific embodiments described, as long as they do not deviate from the structure of the utility model or exceed the scope defined by this claim book, they should all belong to the protection scope of the present utility model.
