Description

Technical Field

[0001] This utility model belongs to the field of ground anchor technology, and in particular relates to a fixed ground anchor for an eVTOL aircraft take-off and landing field. Background Technology

[0002] As a new type of transportation, eVTOL features vertical takeoff and landing, intelligent operation, low cost, low noise, and zero emissions. It can be applied to multiple fields such as urban commuting, tourism, and freight logistics. As its application scenarios continue to expand, market demand is also increasing. This has led to a corresponding increase in the demand for eVTOL takeoff and landing sites. In severe weather such as strong winds, gusts, or typhoons, eVTOL aircraft parked on takeoff and landing sites are easily blown away by strong winds, resulting in damage to themselves or collisions with adjacent aircraft. Therefore, it is necessary to install ground anchors on takeoff and landing sites to secure the aircraft and ensure their safety in case of emergencies.

[0003] When installing ground anchors at aircraft take-off and landing sites, traditional methods of fixing them with ordinary methods are insufficient to provide aircraft with a strong grip. Under the forces generated by frequent take-offs and landings, ground anchors are prone to loosening, affecting overall stability. Moreover, the traditional installation process is not convenient for flexible and appropriate fixing based on actual soil conditions, making it difficult to fully utilize the function of ground anchors. In addition, it is not easy to ensure that ground anchors can withstand the various forces brought by aircraft in the long term after installation. Utility Model Content

[0004] The purpose of this invention is to provide a fixed ground anchor for an eVTOL aircraft take-off and landing field, which solves the problem that when installing ground anchors for aircraft take-off and landing fields, the traditional method of fixing is difficult to provide the aircraft with a sufficiently firm grip. Under the force generated by frequent take-off and landing of the aircraft, the ground anchor is prone to loosening, affecting the overall stability.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a fixed ground anchor for an eVTOL aircraft take-off and landing field, including a base plate, on which a positioning mechanism and a locking mechanism are provided; The positioning mechanism includes a positioning plate disposed on the top surface of the base plate. Four fixing anchors are fixedly connected between the positioning plate and the base plate. Two pre-embedded sleeves are fixedly connected to the top of the positioning plate. Two fixing sleeves penetrate through the base plate and are fixedly connected to the base plate. The two fixing sleeves are respectively located inside the two pre-embedded sleeves. An internal threaded block is fixedly connected to the bottom of each of the two fixing sleeves. Threaded anchors are threadedly connected to the inner walls of the two internal threaded blocks. A helical blade is fixedly connected to the outer wall of the bottom end of each threaded anchor.

[0006] Furthermore, a connecting rod is fixedly connected to the top of each of the two threaded anchors, and each of the two connecting rods extends to the top of the positioning plate, with a lifting ring fixedly connected to the top of each of the two connecting rods.

[0007] Furthermore, the locking mechanism includes four sliding grooves, each formed on the outer wall of the two connecting rods, and a connecting sleeve is slidably connected to the inner wall of the four sliding grooves.

[0008] Furthermore, the top ends of both connecting sleeves extend to the top of the positioning plate, and both connecting sleeves are located inside the two fixed sleeves respectively.

[0009] Furthermore, the outer walls of both connecting sleeves are hinged with four retaining plates, and the two fixed sleeves are provided with four retaining slots, with the retaining plates located inside the retaining slots respectively.

[0010] Furthermore, limit rings are fixedly connected to the outer walls of the top ends of both connecting sleeves, and knobs are rotatably connected to the outer walls of both limit rings.

[0011] Furthermore, the inner walls of the two knobs and the outer walls of the two fixed sleeves are provided with matching threaded grooves, and the knobs are threadedly connected to the fixed sleeves through the threaded grooves.

[0012] Furthermore, the two pre-embedded sleeves are symmetrically arranged on the top of the positioning plate, and the threads of the two helical blades are opposite.

[0013] This utility model has the following beneficial effects: 1. By setting up a positioning mechanism, after the base plate piles are nailed into the soil by multiple fixed anchors, the threaded anchors at the bottom of the fixed sleeve are rotated by manually turning the lifting ring. With the cooperation of the internal threaded block, the threaded anchors drive the spiral blades downward when rotating, thereby screwing the spiral blades into the soil. This allows the ground anchor to further improve the grip of aircraft in the aircraft take-off and landing field and improve the overall stability of the ground anchor.

[0014] 2. With the locking mechanism in place, when the rotating lifting ring moves the connecting rod downwards, the fixed sleeve is in a fixed state, while the connecting sleeve moves upwards relative to the connecting rod. This causes multiple clamping plates to spread outwards and insert into the soil. The modular design of the entire device not only facilitates maintenance and replacement of parts, but also greatly improves the practicality and service life of the device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 As shown, this utility model is a fixed ground anchor for an eVTOL aircraft take-off and landing field, including a base plate 1, on which a positioning mechanism 2 and a locking mechanism 3 are provided; The positioning mechanism 2 includes a positioning plate 21 disposed on the top surface of the base plate 1. Four fixing anchors 22 are fixedly connected between the positioning plate 21 and the base plate 1. Two pre-embedded sleeves 23 are fixedly connected to the top of the positioning plate 21. Two fixing sleeves 24 penetrate the base plate 1 and are fixedly connected to the base plate 1. The two fixing sleeves 24 are located inside the two pre-embedded sleeves 23. Internal threaded blocks 25 are fixedly connected to the bottom of each of the two fixing sleeves 24. Threaded anchors 26 are threadedly connected to the inner walls of the two internal threaded blocks 25. Helical blades 27 are fixedly connected to the outer walls of the bottom ends of the threaded anchors 26. The tops of the two threaded anchors 26 are... A connecting rod 28 is fixedly connected, and both connecting rods 28 extend to the top of the positioning plate 21. A lifting ring 29 is fixedly connected to the top of each of the two connecting rods 28. With the positioning mechanism 2, after the base plate 1 is nailed to the soil by multiple fixed anchors 22, the threaded anchor 26 at the bottom of the fixed sleeve 24 is rotated by manually turning the lifting ring 29. With the cooperation of the internal thread block 25, the threaded anchor 26 drives the spiral blade 27 to move downward when rotating, thereby screwing the spiral blade 27 into the soil. This allows the ground anchor to further improve the grip of aircraft at the aircraft take-off and landing site and improve the overall stability of the ground anchor.

[0021] The locking mechanism 3 includes four sliding grooves 31, each formed on the outer wall of one of the two connecting rods 28. Connecting sleeves 32 are slidably connected to the inner walls of the four sliding grooves 31. The top ends of both connecting sleeves 32 extend to the top of the positioning plate 21. Both connecting sleeves 32 are located inside the two fixed sleeves 24. Four locking plates 33 are hinged to the outer walls of both connecting sleeves 32. Four locking slots 34 are formed on each of the two fixed sleeves 24. Several locking plates 33 are located inside several locking slots 34. Limiting rings 35 are fixedly connected to the top outer walls of both connecting sleeves 32. Knobs 36 are rotatably connected to the outer walls of both limiting rings 35. The inner walls of the two knobs 36... Both the outer walls of the two fixed sleeves 24 are provided with matching threaded grooves 37. The knob 36 is threadedly connected to the fixed sleeve 24 through the threaded grooves 37. The two pre-embedded sleeves 23 are symmetrically arranged on the top of the positioning plate 21. The threads of the two spiral blades 27 are opposite. With the locking mechanism 3, when the lifting ring 29 drives the connecting rod 28 to move downward, the fixed sleeve 24 is in a fixed state, and the connecting sleeve 32 moves upward relative to the connecting rod 28, so that the multiple clamping plates 33 spread away from each other and insert into the soil. The modular design of the whole device not only facilitates maintenance and replacement of parts, but also greatly improves the practicality and service life of the device.

[0022] A specific application of this embodiment is as follows: By setting up a positioning mechanism 2, when installing this device, the base plate 1 is nailed to the ground by fixing anchors 22. The four fixing anchors 22 are distributed in a rectangular shape on the top of the positioning plate 21, which expands the force-bearing area of ​​the overall device and enhances the gripping force of the overall ground anchor. Before nailing the base plate 1 with fixing anchors 22, a groove similar in size to the fixing sleeve 24 is reserved on the soil surface and the two fixing sleeves 24 are placed in the two grooves respectively. After nailing, the threaded anchor 26 at the bottom of the fixing sleeve 24 is rotated by manually twisting the lifting ring 29. With the cooperation of the internal thread block 25, the threaded anchor 26 drives the spiral blade 27 to move downward when rotating, thereby screwing the spiral blade 27 into the soil, so that the two spiral blades 27 can further improve the gripping force of the overall device and improve the stability of the overall ground anchor. With the locking mechanism 3 in place, after the spiral blade 27 is screwed into the soil, the multiple sliding grooves 31 provide clearance for the vertical movement of the connecting sleeve 32, while the knob 36 contacts and is threadedly connected to the outer wall of the fixed sleeve 24 through the threaded groove 37. Due to the limitation of the limiting ring 35, the knob 36 can only rotate on the outer wall of the connecting sleeve 32. Due to the limitation of the multiple sliding grooves 31, the connecting sleeve 32 can only slide up and down on the outer wall of the connecting rod 28. The thread direction of the threaded groove 37 is opposite to the thread direction on the inner wall of the inner threaded block 25. At this time, the knob 36 can be rotated in the opposite direction. When the rotating lifting ring 29 drives the connecting rod 28 to move downward, the fixed sleeve 24 is in a fixed state, and the connecting sleeve 32 moves upward relative to the connecting rod 28. This causes the multiple clamping plates 33 to spread out from each other and insert into the soil. The modular design of the entire device not only facilitates maintenance and replacement of parts, but also greatly improves the practicality and service life of the device.
