Description

Technical Field

[0001] This utility model relates to the field of umbrella and canopy technology, specifically to a novel automatic telescopic curtain umbrella and canopy structure. Background Technology

[0002] As a common agricultural facility, the canopy structure consists of multiple support poles and covering materials. Due to its unique design concept and structural stability, it is widely used in the construction of temporary or permanent sunshade and rain protection facilities. Traditional greenhouse canopy structures are typically operated manually or semi-automatically, and suffer from the following disadvantages: cumbersome operation, inability to quickly respond to sudden weather changes; limited functionality, mainly confined to sunshade and rain protection, lacking environmental adaptability and intelligent control; and material and design limitations leading to short service life and high maintenance costs.

[0003] Traditional canopy structures rely on manual labor for unfolding and rewinding the film when dealing with large-area or high-frequency operations. This process is extremely time-consuming, labor-intensive, and inefficient, especially in the operation of large-area canopies, where the difficulty and labor intensity of manual operation increase significantly [problem].

[0004] In severe weather conditions (such as strong winds or heavy rain), the stability and durability of traditional canopy structures face serious challenges. Due to limitations in structural design, traditional canopies are prone to damage, such as frame deformation and tearing of covering materials, affecting their service life and effectiveness.

[0005] Traditional canopy structures require regular maintenance and inspection to ensure continuous and stable operation. This process is not only cumbersome but also incurs additional maintenance costs. These include labor costs, material costs, and indirect losses due to downtime for repairs, all of which increase the financial burden on users.

[0006] When manually operating a canopy, the operator needs to directly participate in the film rolling process, which increases the risk of injury. Especially at heights or in inclement weather conditions, the operator's safety is difficult to guarantee. Utility Model Content

[0054] Steel rope guide components: including guide wheel 4 and guide frame 5, which are respectively installed on the top of front column 1, guide column 2 and rear column 3, and are used to guide the direction of the steel rope.

[0055] Working principle of the optimal solution

[0056] 9-piece winding spool design:

[0057] The winding drum 9 is provided with a winding area 11 and an unwinding area 10, with a partition plate 12 between them to ensure that the steel rope will not be mixed up during the winding and unwinding process.

[0065] Detailed Workflow

[0066] Initial state:

[0067] The curtain is in a fully folded state, and the steel cable is wound within the take-up area 11 of the winding drum 9. The connection between the curtain and the steel cable can utilize mature technologies, such as the following:

[0068] Hook connection

[0069] Working principle: Small hooks or ring fasteners are installed on the edge of the curtain, and steel wire ropes pass through these hooks or ring fasteners to fix the curtain to the steel wire ropes.

[0070] Clamp-type connection

[0071] Working principle: Special clamps are used to secure the edges of the curtain to the steel wire rope. The clamps can be spring clips, screw clips, or other types.

[0072] stitched connection

[0073] Working principle: A sleeve (usually fabric or mesh material) is sewn along the edge of the curtain, and a steel wire rope passes through this sleeve to fix the curtain to the steel wire rope.

[0074] Adhesive connection

[0075] Working principle: Use high-strength tape or double-sided tape to directly attach the edge of the screen to the steel wire rope.

[0076] snap-fit ​​connection

[0077] Working principle: Plastic or metal clips are installed at the edge of the curtain, and steel wire ropes pass through these clips and are locked in place.

[0078] Unfolding process:

[0079] Step 1: Start the film winding motor 20. The motor drives the transmission shaft 6 to rotate through the drive gear 21 and the transmission gear 22.

[0080] Step 2: The rotation of the drive shaft 6 drives the winding drum 9 to rotate, and the unwinding area 10 on the winding drum 9 begins to unwind the steel rope.

[0081] Step 3: The steel rope is led out from the unwinding area 10 of the winding drum 9, passes through the right guide wheel 13 at the top of the front column 1, and extends along the set guide path to the guide column 2 and the rear column 3.

[0082] Step 4: The steel rope passes through the right guide hole 17 of the guide frame 5 in sequence and continues to extend to the end of the rear column 3.

[0083] Step 5: After the guide is completed at the end of the rear column 3, the steel rope passes through the guide ring 19 and the left guide hole 18 of the guide frame 5 in the same reverse path sequence, and returns to the left guide wheel 14 at the top of the front column 1.

[0084] Step 6: Finally, the steel rope is wound back onto the take-up area 11 of the spool 9 to form a closed loop system, completing the unfolding of the curtain.

[0085] Rewinding process:

[0086] Step 1: Start the film winding motor 20. The motor rotates in the reverse direction, which drives the transmission shaft 6 to rotate in the reverse direction.

[0087] Step 2: The reverse rotation of the drive shaft 6 drives the winding drum 9 to rotate in the opposite direction, and the winding area 11 on the winding drum 9 begins to wind the steel rope.

[0088] Step 3: The steel rope re-enters the winding area 11 of the winding drum 9 from the left guide wheel 14 and is gradually pulled back until the curtain is completely wound up.

[0089] Summary of the working principles of each optimal scheme

[0090] Optimized design of winding spool 9:

[0091] The winding area 11 and the unwinding area 10 are separated: the winding drum 9 is divided into the winding area 11 and the unwinding area 10, with a partition plate 12 in the middle to ensure that the steel rope will not be confused during the winding and unwinding process, thereby improving the stability and reliability of the system.

[0092] Optimized design of steel rope guide components:

[0093] Guide wheel 4: including right guide wheel 13 and left guide wheel 14, hinged to the top of the front column 1, used to guide the steel rope into and out of the winding drum 9.

[0094] Guide frame 5 includes a base 15, a guide plate 16, and a guide ring 19. The base 15 is threaded onto the tops of the guide column 2 and the rear column 3. The guide plate 16 has a right guide hole 17 and a left guide hole 18 on both sides to guide the steel rope through. This design ensures smooth operation of the steel rope throughout the system and reduces the risk of friction and jamming.

[0095] Optimized design of transmission components:

[0096] The drive gear 21 meshes with the transmission gear 22: the drive gear 21 is installed at the output end of the film winding motor 20, and the transmission gear 22 is mounted on the transmission shaft 6. The two mesh to transmit the power of the motor to the transmission shaft 6, ensuring that the winding drum 9 can rotate smoothly. This design improves transmission efficiency and reduces energy loss.

[0097] Summarize

[0098] This novel automatic retractable curtain canopy structure achieves automatic unfolding and rewinding of the curtain through the coordinated action of a film-rolling motor 20, a drive shaft 6, a winding drum 9, and a steel rope guide. Its preferred design further optimizes the design of the winding drum 9, the structure of the steel rope guide, and the coordination of the transmission components, ensuring the stability and reliability of the system.

[0099] The specific workflow is as follows:

[0100] Initial state: The curtain is fully folded, and the steel cable is wound in the take-up area 11 of the winding drum 9.

[0101] Unfolding process: Start the film rolling motor 20, drive the transmission shaft 6 to rotate, drive the winding drum 9 to unwind the steel rope. The steel rope is guided by the guide wheel 4 and the guide frame 5, passing through each column in sequence, and finally forming a closed loop system to complete the unfolding of the curtain.

[0102] Rewinding process: Start the film winding motor 20 to rotate in the opposite direction, and drive the drive shaft 6 to drive the winding drum 9 to wind the steel rope. The steel rope returns to the winding area 11 of the winding drum 9, completing the winding of the curtain.
