The setting of detachable connection of rib units and umbrella cover 1 can realize selecting different quantity of rib units and corresponding umbrella cover 1 according to the diameter size of trees, and the setting of metal ring 10 endotheca is equipped with ring cable 11 can make rib units form annular stable structure, and the combination of toothed rubber contact plate 7 and rotating parts can realize collecting umbrella and the surface close contact of trees to effectively prevent to collect the phenomenon that the umbrella from appearing the landing in the use.
The rotating part comprises a ball bowl 5 connected with the bottom end of the umbrella ridge telescopic supporting rod 4, a ball head 6 is arranged in the ball bowl 5, and the ball head 6 is fixedly connected with the toothed rubber contact plate 7 through a short rod 12. The arrangement of the ball head 6 and the ball bowl 5 can enable the position of the toothed rubber contact plate 7 to be adjustable, the contact position of the toothed rubber contact plate 7 is selected according to the roughness of the tree surface, the friction force between the toothed rubber contact plate 7 and the tree surface is improved, and the phenomenon that the collecting umbrella slides off during use can be effectively prevented.
One end of the endless cable 11 is connected with the first screw rod 14, the other end of the endless cable 11 is connected with the second screw rod 15, and the first screw rod 14 is detachably connected with the second screw rod 15 through the turnbuckle nut 16. The ring cable 11 is detachably connected through the first screw 14, the second screw 15 and the basket bolt nut 16, and is screwed after passing through the metal ring 10, so that the rib unit forms a stable ring structure.
The umbrella surface 1 is trapezoidal, two sides and the bottom edge of the umbrella surface 1 are provided with fixing parts 17 at equal intervals, and the umbrella ridge fixed-length stay bar 2, the umbrella ridge threaded sleeve 3 and the ridge side wave stay bar 9 are detachably connected with the umbrella surface 1 through the fixing parts 17. The umbrella cover 1 is detachably connected with the umbrella rib unit through the fixing part 17, and has the characteristics of convenience in installation and detachment and wide application range.
The fixing part 17 is a connecting buckle or a fixing strip, and a magic tape or at least one button is arranged on the fixing strip.
The umbrella cover 1 comprises a base layer and a waterproof layer coated on the base layer, wherein the base layer is formed by weaving high-temperature resistant fibers, and the high-temperature resistant fibers are one or more of polytetrafluoroethylene fibers, polyamide fibers, polyphenylene sulfide fibers, aluminum oxide fibers, silicon carbide fibers and boron nitride fibers. The base layer of the umbrella cover 1 is woven by high-temperature resistant fibers, so that the collecting umbrella has fireproof performance, and the waterproof layer can enable the collecting umbrella to have rainproof performance.
The umbrella surface 1 is made of fire-resistant waterproof fabric through spinning by using PTFE glass fibers in the embodiment, two annular long sides of the umbrella surface 1 are connected with two adjacent umbrella ridge fixed-length stay bars 2 and umbrella ridge threaded sleeves 3, the radial outer side edges of the umbrella surface 1 are not connected in the radial direction, the radial inner sides of the umbrella surface 1 are respectively connected with ridge-side wave stay bars 9 in a tensioning state. The two ridge side wave stay bars 9 are V-shaped in the vertical direction after the installation, and the annular cross section shape of the umbrella surface 1 is gradually transited from the straight tensioning state of the outer end of the fixed-length stay bar to the V-shaped wave trough state of the ridge wave trough stay bar.
The ridge-side wave stay bar 9 can only rotate around the rotating shaft 13 in a vertical plane, deformation in the plane is restrained by clamping of the lug plates 8, the ring rope 11 sequentially passes through the metal rings 10, and the two end rings of the ring rope 11 are connected by screwing the first screw rod 14 and the second screw rod 15 into the basket bolt nuts 16.
When the tree fallen leaf collecting umbrella is not used, the first screw rod 14 or the second screw rod 15 at one end of the ring rope 11 is screwed out from the flower basket screw bolt and nut 16, so that the ring rope 11 is separated from the metal ring 10, one side of at least one umbrella face 1 in each umbrella face 1 is connected with the fixing part 17 of the corresponding umbrella rib unit to be in an unlocking state, and the whole set of device is in a folding state.
The installation process is as follows: firstly, each rib unit is symmetrically arranged around the trunk in the circumferential direction, and then each umbrella cover 1 is connected with each corresponding rib unit. The rib unit is then lifted with the canopy 1 to a level off the root. Then the telescopic struts 4 are rotated to extend from the threaded sleeves 3 until the toothed rubber contact plates 7 are respectively abutted against the corresponding positions of the trunk. Since the trunk cross section is not regular circular, the extension length of each umbrella rib telescopic stay rod 4 is different. Because the ball head 6 adjacent to the toothed rubber contact plate 7 can rotate by a certain extent according to the specific shape of the trunk surface of the contact position, each rubber tooth on the toothed rubber contact plate 7 can be well attached to the trunk surface of the contact position.
Then the first screw 14 of the endless cable 11 is passed circumferentially through the metal rings 10 of each rib unit in turn, and the second screw 15 at the other end of the endless cable 11 is screwed into the basket bolt nut 16, so that the endless cable 11 forms a closed loop configuration. The second screw 15 is then rotated so that the endless cable 11 is tensioned, in which a certain pretension is generated. So far, the whole collecting umbrella structure forms a stable structural system, and the installation is finished.
The pretension of the circumferential cable 11 is transmitted through the metal ring 10 and the ridge-side wave struts 9, creating a certain magnitude of radially inward tension and a smaller magnitude of counter-clockwise bending moment in the rib unit outwards about the circumferential axis. The radial inward tension force enables the toothed rubber contact plate 7 to generate certain pressure with the trunk, and then under the action of vertical load, static friction force and biting force are generated between the contact surfaces, and the static friction force and the biting force prevent the fallen leaf collecting umbrella from sliding down vertically, so that the vertical stability of the structure is maintained. The anticlockwise bending moment causes each rib unit to rotate anticlockwise downwards around the ball head 6 to deform, the distance between the tail ends of the fixed-length struts 2 of each rib is increased, but the umbrella cover 1 connected between the outer ends of the fixed-length struts 2 of each rib is in an overall open state at the beginning. The aforementioned trend necessarily causes tensile stress in the canopy 1 connected between the outer ends of the respective rib fixed-length struts 2, which prevents the trend of increasing the spacing between the distal ends of the respective rib fixed-length struts 2, and thus prevents the respective rib units from being deformed in a counterclockwise and downward rotation about the ball head 6 and forms a mechanical balance. Under the action of lateral wind load, the geometry of the fallen leaf collecting umbrella structure is stable due to the stretching limiting action of the umbrella cover 1.
The operation mechanism of the invention is as follows:
after installation, a stable self-balancing collecting umbrella structure is formed under the crown. When fallen leaves are generated in the crown, the fallen leaves fall into the lower collecting umbrella cover 1. As the fallen leaves are lighter and the umbrella cover 1 has better elastic deformation characteristic, the fallen leaves can be stacked in the umbrella cover 1 layer by layer, thus avoiding the fallen leaves from being directly scattered on various roads below the trees. And the fallen leaves in the film can be cleaned after a plurality of days, and the fallen leaves do not need to be cleaned every day.
When the fallen leaves are piled up to a certain amount, municipal cleaning personnel can lightly prop up the bottom of the umbrella cover 1 from the bottom, so that the fallen leaves slide from the middle of the umbrella cover 1 to the edge of the umbrella cover 1 on one side close to the trunk, and finally fall from a gap between the ridge side wave stay bar 9 of the collecting umbrella and the trunk, and can be packaged and transported away in time. Or directly removing each umbrella cover 1, conveying the umbrella cover 1 and the accumulated fallen leaves thereon to a transport vehicle, unloading the fallen leaves on the transport vehicle, withdrawing the umbrella cover 1 and installing the fallen leaves between the rib units. In the time of cleaning fallen leaves in the film for a few days, the fallen leaves can not fly out along with wind even if windy due to the shielding effect of the trough of the umbrella cover 1.
In addition, during raining, because the umbrella cover 1 is watertight, a larger rain-shielding space can be formed below the whole collecting umbrella structure, and the passing of personnel below trees is facilitated. The umbrella cover 1 is subjected to certain beautifying and modifying, and the whole umbrella collecting structure can also play a role in beautifying urban environments.
The invention can collect fallen leaves of trees at any time, can effectively avoid random scattering of fallen leaves on various roads near the trees, does not need to clean the fallen leaves every day, and has the characteristics of wide application range, reasonable design and convenient installation and disassembly.
