Description

Technical Field

[0001] This utility model relates to the field of greening maintenance and sun protection technology, and more specifically, it relates to a greening maintenance and sun protection device. Background Technology

[0002] In the field of modern urban greening maintenance, with the acceleration of urbanization and the intensification of climate change, the health management of urban green belts is facing unprecedented challenges. Especially under the conditions of high temperature and strong light radiation in summer, newly planted saplings, lawns and various flowers are very susceptible to sunburn damage, which seriously affects the growth status of plants and the effect of urban landscape.

[0003] Among existing green space maintenance and sun protection technologies, the most common solution is to equip the green belt with a sunshade net made of polyethylene or polypropylene, and suspend it above the green belt using a pull rope component to reduce the damage of direct sunlight to the plants. This type of sun protection device usually uses simple metal or plastic ground nails as a fixing method. However, this traditional fixing method has serious technical defects: First, most conventional ground nails have a smooth outer wall design and lack an effective anti-pull-out structure. The fixing force in the soil mainly relies on the friction between the nail and the soil. When encountering strong winds, heavy rain, etc. During severe weather, the sunshade netting exerts a continuous pulling force on the ground stakes under external forces, causing the stakes to gradually loosen and eventually detach from the soil. The loosening and detachment of the sunshade netting not only renders its sun protection function ineffective, exposing plants to strong sunlight and causing damage, but also causes the sunshade netting to be blown away by the wind, polluting the environment and potentially getting tangled in the plants, causing mechanical damage, and even creating safety hazards on urban roads. In addition, the frequent detachment of the sunshade netting requires maintenance personnel to constantly reinstall it, greatly increasing labor intensity and maintenance costs, while also resulting in the waste of ground stakes and sunshade netting materials and premature scrapping.

[0004] Secondly, another prominent problem exposed in the practical application of existing greening maintenance sun protection devices is the cumbersome nature of installing and dismantling sunshade nets. With seasonal changes and climate variations, the demand for greening sun protection exhibits a clear cyclical characteristic. Sun protection facilities typically need to be installed before the high temperatures of summer and removed promptly after the autumn temperatures drop to ensure plants receive suitable light conditions. However, the installation and dismantling process of existing sunshade nets is extremely complex, usually requiring the use of specialized ground stake installers, hammers, nail pullers, and other tools. This process is not only time-consuming and labor-intensive but also prone to deformation or breakage of the ground stakes due to improper operation. More importantly, because each installation or dismantling requires… The repeated process of inserting and removing ground nails not only accelerates their wear and deformation, reducing their lifespan, but also continuously disturbs the soil structure, damaging the plant root growth environment and potentially harming shallow roots, thus adversely affecting plant health. Furthermore, in practice, removed ground nails are often lost, requiring additional replacements during subsequent installations, increasing material costs and environmental burden. For scenarios requiring frequent adjustments to the height or coverage of sunshade nets, such as those needing flexible adjustments based on plant growth or changes in light intensity, this cumbersome installation and disassembly method is almost impossible to meet practical needs, severely limiting the flexibility and maintenance effectiveness of sunshade facilities.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a greening maintenance and sun protection device, which has the following features:

[0018] Beneficial effects:

[0019] 1. The overall design cleverly integrates core components such as sunshade nets, pull ropes, and connecting sleeves to form a systematic plant protection solution. This device fully considers the special protection needs of urban green belts under high temperature and strong light environments. Through the scientific configuration of the synergistic work of the sunshade net and the ground fixing system, it effectively solves the core problem of sunshade nets being prone to loosening and falling off in existing technologies. In particular, the optimized connection design between the sunshade net and the pull rope allows the sunshade coverage area to be flexibly adjusted according to the distribution of plants. The matching design of the connecting sleeve and the fixing rod enables the quick connection between the sunshade net and the ground fixing device, and installation can be completed without any complicated tools. At the same time, the multi-point distributed design of the pull rope ensures that the sunshade net is evenly stressed, ensuring the growth safety of urban green plants. It also significantly reduces the manpower and material costs of greening maintenance by reducing the frequency of maintenance and extending the service life of the equipment, providing more efficient, reliable, and economical technical support for urban greening management.

[0020] 2. The fixing device innovatively solves the technical problem of unreliable fixing of traditional sunshade net ground nails through a clever combination of insert sleeve, fixing plate, relief groove, top rod, tension spring, opening and closing plate, push rod and rotating shaft. Its core highlight is the use of an unfoldable structure design similar to a "mechanical anchor". This mechanical unfolding structure transforms the originally simple ground nail into a ground anchor with active ground gripping ability, significantly improving the fixing force in various soils. Especially in severe weather such as strong winds and heavy rain, the greater the external force, the greater the embedding pressure of the opening and closing plate on the surrounding soil, forming an adaptive and enhanced fixing effect. The tapered design of the insert sleeve at the bottom reduces the initial insertion resistance, making installation easier. Compared with traditional smooth ground nails, the gripping area of ​​this fixing device is increased by 3-5 times and the fixing force is increased by more than 200%. It can maintain excellent stability even in soft sandy soil or muddy soil after rain.

[0021] 3. The locking device integrates precision components such as a fixing rod, control sleeve, release sleeve, screw, fixing sleeve, fixing block, pressure sleeve, external gear, internal gear, fixing platform, and storage slot. It creatively solves the cumbersome technical problem of installing and disassembling sunshade nets. The device employs a highly integrated mechanical quick-locking and releasing mechanism. This precise coordination of gear transmission and slider guidance allows the entire locking and releasing process to be completed with a simple rotation operation, requiring no professional tools. Operation time is reduced to less than 1 / 5 of traditional methods. The handle at the top further facilitates manual operation, making it easy to complete even while wearing gardening gloves. The inclined design of the guide platform... The automatic guidance and positioning during the insertion of the fixing rod greatly improves installation efficiency and accuracy, perfectly solving the problem of rapid connection between the sunshade net and the ground fixing device. This allows the installation and dismantling of the sunshade net to be completed at any time without changing the buried state of the fixing device, completely avoiding the damage to the soil structure and plant root system caused by repeatedly inserting and removing ground nails in traditional technology. This efficient and convenient snap-fit ​​system not only significantly reduces the labor intensity and time cost of greening maintenance, but also makes the seasonal installation and dismantling of the sunshade net extremely simple. It can even flexibly adjust the sunshade facilities according to the weather forecast, providing unprecedented operational flexibility and economic benefits for urban greening management.

The top rod 5 is slidably installed on the side wall of the sleeve 2. The two ends of the tension spring 6 are respectively connected to the inner side of the opening and closing plate 7 and the inner wall of the clearance groove 4. The opening and closing plate 7 is rotatably installed in the clearance groove 4 via the rotating shaft 9. The push rod 8 is detachably inserted into the sleeve 2. A snap-fit ​​device is connected to the top of the sleeve 2. The snap-fit ​​device includes a fixing rod 10, a control sleeve 11, a release sleeve 12, a screw 13, a fixing sleeve 14, a fixing block 15, a pressure sleeve 16, and an external gear 1. 7. An internal gear 18, a fixed platform 19, and a storage slot 20 are provided. A fixed rod 10 is fixedly connected to one end of a push rod 8.

[0032] A pull rope 21 is connected to the outer side of the sunshade net 1, and a connecting sleeve 22 is connected to the other end of the pull rope 21. The connecting sleeve 22 is fitted onto the outer side of the fixed rod 10.

[0033] In this embodiment, when the sunshade net 1 needs to be installed, firstly, the insert 2 is hammered into the soil so that the lower section of the fixing plate 3 contacts the ground, and the fixing sleeve 14 is placed on the ground. Then, the sunshade net 1 is placed over the green belt, and then the connecting sleeve 22 is fitted onto the outside of the fixing rod 10. Then, the push rod 8, along with the fixing rod 10, is inserted into the fixing sleeve 14, and then the push rod 8 enters the insert 2. Then, the push rod 8 pushes the top plate 27 outward, causing the top plate 27 to drive the top rod 5 to slide outward, and causing the top plate 27 to compress some of the set top springs 28. At the same time, the other end of the top rod 5 pushes the opening and closing plate 7 outward, causing the opening and closing plate 7 to rotate out of the relief groove 4 along the rotating shaft 9, so that the opening and closing plate 7 spreads open, improving the grip. Ensure the secure installation of the insert 2. Simultaneously, the inner wall of the fixing platform 19 presses against the outer side of the fixing block 15, causing the fixing block 15 to be squeezed into the storage groove 20 and press against the push spring 29. When the fixing block 15 moves to one side of the fixing platform 19, that is, the push rod 8 is fully inserted into the insert 2. The fixing rod 10 and the fixing sleeve 14 press the connecting sleeve 22 tightly in the middle. At this time, the push spring 29 resets and pushes the fixing block 15, causing the fixing block 15 to slide out of the storage groove 20 and causing one side of the fixing block 15 to fit against the fixing platform 19, so that the fixing block 15 and the fixing platform 19 form a locking relationship, making it impossible for the fixing rod 10 and the push rod 8 to be pulled out. Then, refer to the above steps to fix the connecting sleeve 22 connected to one end of the other pull rope 21, thereby realizing the installation of the sunshade net 1.

[0034] Please see Figures 1-5 As a further implementation of the overall equipment: a handle 23 is connected to the top of the fixing rod 10.

[0035] The side wall of the fixed sleeve 14 is provided with a groove 24, and a slider 25 is provided in the groove 24. The inner wall of the release sleeve 12 is fixedly connected to the outer wall of the pressure sleeve 16 through the slider 25.

[0036] The bottom of the insert 2 has a tapered structure design.

[0037] A guide platform 26 is fixedly provided in the fixed sleeve 14. The guide platform 26 has an inclined structure design.

[0038] One end of the push rod 5 is connected to a top plate 27. The inner wall of the top plate 27 fits against the outer wall of the push rod 8. A top spring 28 is movably sleeved on the outer side of the push rod 5. The two ends of the top spring 28 are connected to the inner wall of the top plate 27 and the insert 2, respectively.

[0039] A push spring 29 is movably installed in the storage slot 20, and one side of the fixing block 15 is connected to the inner wall of the storage slot 20 through the push spring 29.

[0040] More specifically, when the sunshade net 1 needs to be removed, first rotate the control sleeve 11 forward, causing the control sleeve 11 to drive the internal gear 18 on one side to rotate forward. Then, the internal gear 18 drives multiple meshing external gears 17 to rotate. Then, the external gears 17 drive the screw 13 to rotate. Since the release sleeve 12 is movably connected to the screw 13 through threads, the release sleeve 12 drives the slider 25 to move along the slide groove 24. The slider 25 will drive the pressure block to slide in the fixing sleeve 14. Then, the pressure block presses the fixing block 15 inward, so that the fixing block 15 gradually retracts into the storage groove 20 and squeezes the push spring 29. Then, the fixing block 15 is no longer locked with the fixing platform 19. Then, the fixing rod 10 is lifted upward by the handle 23, so that the fixing... Rod 10 drives push rod 8 to be pulled out of insert sleeve 2. Then, one side of top plate 27 is no longer limited by the outer wall of push rod 8. Then, top spring 28 pushes top plate 27 to slide and reset, so that top plate 27 drives top rod 5 to slide and reset. Due to the presence of soil, opening and closing plate 7 will not reset. Then, push rod 8 is completely pulled out. Then, connecting sleeve 22 sleeved on the outside of fixed rod 10 is removed. Then, other push rods 8 and fixed rods 10 are removed in sequence. Then, other connecting sleeves 22 are removed. Then, sunshade net 1 is removed. To prevent loss, control sleeve 11 is rotated in the opposite direction, so that release sleeve 12 drives pressure sleeve 16 to slide and reset through slider 25. Then, push rod 8 is reinserted into insert sleeve 2, and fixed rod 10 is locked into the inside of fixed sleeve 14.

[0041] In summary, when using or operating the overall equipment: First, hammer the insert 2 into the soil so that the lower section of the fixing plate 3 contacts the ground, placing the fixing sleeve 14 on the ground. Then, place the sunshade net 1 over the green belt. Next, fit the connecting sleeve 22 onto the outside of the fixing rod 10. Then, insert the push rod 8 along with the fixing rod 10 into the fixing sleeve 14, allowing the push rod 8 to enter the insert 2. The push rod 8 then pushes the top plate 27 outwards, causing the top plate 27 to slide outwards along the top rod 5, compressing the top springs 28. Simultaneously, the other end of the top rod 5 pushes the opening and closing plate 7 outwards, causing the opening and closing plate 7 to rotate out of the relief groove 4 along the rotating shaft 9, opening and closing the plate 7. Increase grip to ensure the stable installation of the insert 2. At the same time, the inner wall of the fixing platform 19 presses against the outer side of the fixing block 15, causing the fixing block 15 to be squeezed into the storage groove 20 and press against the push spring 29. When the fixing block 15 moves to one side of the fixing platform 19, that is, the push rod 8 is fully inserted into the insert 2. The fixing rod 10 and the fixing sleeve 14 press the connecting sleeve 22 tightly in the middle. At this time, the push spring 29 resets and pushes the fixing block 15, causing the fixing block 15 to slide out of the storage groove 20 and causing one side of the fixing block 15 to fit against the fixing platform 19, so that the fixing block 15 and the fixing platform 19 form a locking relationship, making it impossible for the fixing rod 10 and the push rod 8 to be pulled out. Then, follow the above steps to fix the connecting sleeve 22 connected to one end of the other pull rope 21, thereby realizing the installation of the sunshade net 1.

[0042] When the sunshade net 1 needs to be removed, first rotate the control sleeve 11 clockwise, causing the control sleeve 11 to drive the internal gear 18 on one side to rotate clockwise. Then, the internal gear 18 drives multiple meshing external gears 17 to rotate. Then, the external gears 17 drive the screw 13 to rotate. Since the release sleeve 12 is movably connected to the screw 13 through threads, the release sleeve 12 drives the slider 25 to move along the slide groove 24. The slider 25 will drive the pressure block to slide in the fixing sleeve 14. Then, the pressure block presses the fixing block 15 inward, so that the fixing block 15 gradually retracts into the storage groove 20 and squeezes the push spring 29. Then, the fixing block 15 is no longer locked with the fixing platform 19. Then, the fixing rod 10 is lifted upward by the handle 23, so that the fixing rod 1... 0 drives the push rod 8 to be pulled out of the insert sleeve 2. Then, one side of the top plate 27 is no longer limited by the outer wall of the push rod 8. Then, the top spring 28 pushes the top plate 27 to slide and reset, so that the top plate 27 drives the top rod 5 to slide and reset. Due to the presence of soil, the opening and closing plate 7 will not reset. Then, the push rod 8 is completely pulled out. Then, the connecting sleeve 22 sleeved on the outside of the fixed rod 10 is removed. Then, the other push rods 8 and fixed rods 10 are removed in sequence. Then, the other connecting sleeves 22 are removed. Then, the sunshade net 1 is removed. To prevent loss, the control sleeve 11 is rotated in the opposite direction, so that the release sleeve 12 drives the pressure sleeve 16 to slide and reset through the slider 25. Then, the push rod 8 is reinserted into the insert sleeve 2, and the fixed rod 10 is locked into the inside of the fixed sleeve 14.
