Description

Greenhouse roller shutter rope protection device and greenhouse

Technical Field

The utility model relates to the technical field of greenhouses, in particular to a greenhouse rolling curtain rope protection device and a greenhouse.

Background

In the north of China, the season suitable for planting in one year is very short, and the requirements of the daily life of residents cannot be met. Therefore, the greenhouse is greatly popularized, and one of the most influential factors in greenhouse planting is temperature. In order to keep warm at night in winter, the plastic films of the existing greenhouse are provided with heat preservation quilts (also can be heat preservation straw mats, plastic films and the like), the heat preservation quilts are rolled up in the daytime so as to increase illumination and lighting, raise temperature, promote crop growth and place the quilts at night so as to keep the temperature in the greenhouse.

Traditional heat preservation quilt needs manual rolling, generally carries out a rolling work and needs one to two hours. To increase efficiency, roller blinds have appeared on the market, for example chinese patent application (CN 216087958U) discloses a roller blind mechanism for greenhouses comprising a rotatable roller blind shaft; the rolling curtain is longitudinally arranged, the upper end is a fixed end, and the lower end is a free end; the first end of the rope is fixed on the upper part of the back surface of the roller shutter, and the second end of the rope penetrates out forwards from the lower end of the back surface of the roller shutter and extends upwards from the front surface of the roller shutter to the roller shutter shaft; when the roller shutter shaft rotates, the second end of the rope is pulled, and the roller shutter is driven to wind.

However, it is noted that the rope is completely exposed to the outside space when it is wound around the roller shutter shaft in the daytime, and thus, the rope is exposed to sunlight, which has a great influence on the life of the rope, and it is generally only used for one to two years, and the cost of the rope itself is high, which becomes a burden to farmers. In addition, as the connection part of the rope and the roller shutter shaft is also exposed, in the winding process, objects are easily clamped at the connection part of the rope and the roller shutter shaft, equipment is easily damaged, and in some cases, personal safety risks exist when people are too close to the connection part.

Detailed Description

Fig. 1 shows a schematic diagram of connection between a roller shutter rope and a roller shutter shaft in the prior art, referring to fig. 1, a first end 11 of the roller shutter rope 1 is fixedly connected to the roller shutter shaft 2, a hollow cylindrical winding body 12 is formed by winding the middle part of the roller shutter rope 1 around the periphery of the roller shutter shaft 2, a second end 13 of the roller shutter rope 1 extends from the right end of the winding body 12 and is connected to a roller shutter (not shown), a driving device (not shown) is connected to the roller shutter shaft 2, and the driving device drives the roller shutter shaft 2 to rotate, so that the roller shutter rope 1 is wound or unwound, and further the roller shutter is wound and unwound. Other structures of the roller shutter mechanism can refer to a roller shutter mechanism for a greenhouse disclosed in Chinese patent (CN 216087958U).

Note that the above-mentioned rolling cord 1 is directly wound on the rolling cord shaft 2, and no other structure is used for shielding the rolling cord 1, so that most of the surface of the rolling cord 1 is exposed to the outside, and when the rolling cord is wound in daytime, the rolling cord 1 is also wound on the rolling cord shaft 2, and at this time, the rolling cord 1 is irradiated by sunlight, so that the performance of the material is affected, the aging of the material is aggravated, and the service life of the rolling cord 1 is finally affected. In addition, the connection 14 between the blind cord 1 and the blind shaft 2 at the time of winding is also exposed, so that when an object is located at the connection 14 between the two, the object will be wound between the blind cord 1 and the blind shaft 2, not only affecting the winding of the subsequent blind cord 1, but also possibly damaging the blind cord 1. In some cases, if the object is a part of the human body (such as hair, arms, fingers, etc.), the human body may be damaged.

The embodiment of the utility model provides a greenhouse roller shutter rope protection device, which protects a roller shutter rope 1 wound on a roller shutter shaft 2 from sun exposure, prolongs the service life of the roller shutter rope 1, protects a joint 14 of the roller shutter rope 1 and the roller shutter shaft 2, prevents objects from entering the joint 14, and improves the safety performance.

Fig. 2 shows a schematic view of a protection device for a greenhouse rolling rope, which is provided by the embodiment of the utility model, and is shown in fig. 2, and comprises a rolling rope 1, a rolling shaft 2 and a protector 3. The connection relationship between the roller shutter rope 1 and the roller shutter shaft 2 is the same as that of the prior art, and is not repeated. The protector 3 includes a cover plate 31 and a through hole 32. The cover plate 31 can cover at least part of the surface of the blind shaft 2 and the blind cord 1 can be at least partially located between the cover plate 31 and the blind shaft 2. The fact that the cover plate 31 can cover at least a part of the surface of the roller shutter shaft 2 means that the cover plate 31 is disposed above and/or laterally of the roller shutter shaft 2, and the orthographic projection formed after the sun irradiates the cover plate 31 completely covers the boundary of the wound body 12. Specifically, in the length direction, the length of the covering plate 31 is at least greater than or equal to the length formed by winding the winding rope 1 around the winding shaft 1, that is, when the winding rope 1 is in the wound state, the covering plate 31 can completely cover the winding rope 1 on the winding shaft 1. The maximum value of the dimension of the cover plate 31 in the width direction should be larger than the sum of the diameter of the blind shaft 2 and twice the diameter of the blind cord 1. The fact that the blind cord 1 can be at least partially located between the cover plate 31 and the blind shaft 2 means that a winding space is formed between the lower surface of the cover plate 31 and the upper surface of the blind shaft 2, and the radial size of the winding space is at least greater than the diameter of the blind cord 1, so that the blind cord 1 can be smoothly wound in the winding space. In addition, the through hole 32 may be provided near the right end of the winding body 12, through which the second end 13 of the winding rope 1 is outwardly penetrated, and the diameter of the through hole 32 is slightly larger than that of the winding rope 1, for example, the diameter of the through hole 32 is 1.1 to 2.0 times that of the winding rope 1, and such a hole diameter can ensure that the winding rope 1 normally moves in the through hole 32 while preventing other objects from entering the inside of the through hole 32.

Therefore, after the winding rope 1 is wound, the boundary of the winding body 12 is located inside the cover plate 31, namely, the cover plate 31 completely covers the upper part of the winding body 12, so that the situation that the winding rope 1 is irradiated by sunlight after being wound in the daytime is avoided, and compared with the prior art, the service life of the winding rope 1 can be prolonged. In addition, since the roller blind rope 1 is penetrated out of the through hole 32, an external object is blocked outside the through hole 32 in the rolling process and is not wound on the joint 14 of the roller blind shaft 2 and the roller blind rope 1, thereby improving the safety.

With continued reference to fig. 2, in this embodiment, the cover plate 31 is in an upwardly protruding arc shape, the radius of the arc is larger than that of the roller shutter shaft 2, and the front and rear ends of the arc extend downward below the highest point of the roller shutter shaft 1, so that the arc can cover the wound body 12 at least from the lateral part, and the protection effect on the wound body 12 is further improved.

With continued reference to fig. 2, in this embodiment, the protector 3 further includes a ring 33, where the ring 33 is fixedly connected with the cover plate 31, and the through hole 32 is disposed on the outer peripheral surface of the ring 33, so that the protector 3 can be mounted on the outer periphery of the roller shutter shaft 2 by disposing the ring 33, and as the winding action proceeds, the protector 3 is further moved along the axial direction of the roller shutter shaft 2 under the driving of the roller shutter rope 1, for example, when the winding is performed, the protector 3 is moved from left to right, and when the unwinding is performed, the protector 3 is moved from right to left.

In the present embodiment, the ring body 33 is provided at an end of the cover plate 31, and is integrally formed with the cover plate 33, so as to facilitate the manufacture of the protector 3. But in other embodiments the ring 33 and the cover plate 31 may be removable to facilitate replacement of the cover plate 31 or ring 33 at any time.

It should be noted that, the ring body 33 generally needs to have a certain axial length, for example, 2-5 cm, so as to ensure that the ring body 33 can be stably mounted on the outer periphery of the roller shutter shaft 2. The radial distance between the ring 33 and the roller shutter shaft 2 is greater than the diameter of the roller shutter rope 1 so that the roller shutter rope 1 can be smoothly wound around the outer circumference of the roller shutter shaft 2 after being extended from the through hole 32.

The ring body 33 may be a ring shape that is fully closed in the circumferential direction or a ring shape that forms a notch in the circumferential direction, but generally requires more than 3/4 of an arc, specifically, only the ring body 33 needs to be sleeved on the outer periphery of the roller shutter shaft 2.

The outer peripheral surface of the ring body 33 can be provided with the boss 331 protruding outwards, the boss 331 is of a hollow structure, and the through hole 32 is positioned at the outer end of the boss 331, so that when the roller shutter rope 1 is connected with the ring body 33, the roller shutter rope 1 is limited and guided by the boss 331, and the roller shutter rope 1 can be wound and unwound conveniently.

When the greenhouse winding device is used for winding, the roller shutter shaft 2 rotates along the first direction, and the outer peripheral surface of the roller shutter shaft 2 drives the roller shutter rope 1 to be wound on the roller shutter shaft 2 through friction. Specifically, as the roller shutter shaft 2 rotates, the second end 13 of the roller shutter rope 1 enters the inside of the ring body 33 from the through hole 32 and winds around the surface of the roller shutter shaft 2 to form the wound body 12, and as the roller shutter shaft 2 rotates, the ring body 33 moves correspondingly along the axial direction of the roller shutter shaft 2.

When the greenhouse winding device is used for unwinding, the roller shutter shaft 2 rotates along a second direction (opposite to the first direction), and the outer peripheral surface of the roller shutter shaft drives the roller shutter rope 1 to leave from the roller shutter shaft 2 through friction. Specifically, as the roller shutter shaft 2 rotates, the second end 13 of the roller shutter rope 1 is moved away from the through hole 32, the length of the winding body 12 is gradually reduced, and the ring body is correspondingly moved in the axial direction of the roller shutter shaft 2 as the roller shutter shaft 2 rotates.

The embodiment of the utility model also provides a greenhouse, and a roller shutter mechanism is arranged on the greenhouse and comprises the roller shutter rope protection device.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present utility model. Various modifications to these embodiments will be readily apparent to those skilled in the art. The generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the utility model.
