Abstract
Description
Technical fields:
[0001] This utility model relates to the field of bird net pole accessories, specifically to a basic structure for a bird-blocking net pole. Background technology:
[0002] To ensure the efficiency and safety of bird control operations, most airports now install bird poles and nets within the lifting area. Regulations stipulate that there should be no protruding steel pipe bases within the lifting area; if present, they should be removed or their height should be ensured to not protrude above the ground. However, while meeting the height requirement, the bird pole foundations are exposed to the air for extended periods, leading to a significant accumulation of dust inside the pole sleeves. When replacing the poles, this accumulated dust or gravel immediately sinks to the bottom of the sleeves, greatly reducing their usable length. Therefore, it is necessary to periodically excavate the original foundations using small excavators and cranes to empty the dust and gravel to restore the sleeve's usable length, increasing labor intensity and impacting replacement efficiency. Utility Model Content:
[0003] In view of this, the present invention provides a simple structure for bird-blocking net poles that can be quickly installed and disassembled.
[0004] The purpose of this utility model is achieved by the following technical solution: a basic structure for a bird-blocking net pole, including a fixed base and a core-pulling component. The fixed base has a receiving cavity in the middle of its upper part. The shape of the receiving cavity matches that of the core-pulling component. The core-pulling component is placed in the receiving cavity. Several reserved holes for inserting bird poles are opened on the upper part of the core-pulling component. A handle is also provided on the upper part of the core-pulling component.
[0005] Furthermore, the core-pulling component consists of two symmetrically spliced inner cores. Each of the two inner cores has several semi-circular grooves on its opposite side along the vertical direction. Each pair of corresponding grooves is combined to form the reserved hole.
[0006] Furthermore, the diameter of each of the reserved holes is different.
[0007] Furthermore, the fixed base is a square structure, precast from concrete.
[0008] Furthermore, the core-pulling component has a square structure, and each inner core is precast from concrete.
[0009] Furthermore, a handle is fixedly installed on the top of each inner core.
[0010] Furthermore, the surface of each inner core that contacts the inner wall of the accommodating cavity is coated with an insulating oil layer.
[0011] Advantages of utility models:
[0012] This invention reduces on-site wet work and improves construction efficiency by prefabricating the fixed base and core-pulling components in the factory; the reusable base reduces the frequency of replacement, thereby reducing long-term maintenance and replacement costs; the installation mechanism of this invention makes the bird pole assembly and disassembly faster, greatly improving installation efficiency; the modular design of the bird pole allows for quick replacement of damaged individual parts without the need for complete replacement.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] like Figure 1-3 As shown, a bird-blocking net pole base structure includes a square-shaped fixed base 1 precast from C30 plain concrete. Other shapes can also be used for the overall shape of the fixed base 1, such as a cylinder or a polygonal structure. In this embodiment, a square structure with dimensions of 600 mm × 600 mm is preferred. An accommodating cavity 11 is provided in the middle of the upper part of the fixed base 1. It is a rectangular cavity with a square bottom surface, a depth of 400 mm, and a bottom length and width of 212 mm.
[0020] The system also includes a core-pulling component 2. The shape of the receiving cavity 11 matches that of the core-pulling component 2. The core-pulling component 2 has a square bottom surface with a height of 400 mm and a bottom length and width of 200 mm. It is precast from C30 plain concrete. The core-pulling component 2 is placed inside the receiving cavity 11. Several reserved holes 21 with different diameters are opened on the upper surface of the core-pulling component 2. The depth of the reserved holes 21 is the same as the height of the core-pulling component 2. Bird rods are inserted into the reserved holes 21. Each reserved hole 21 can accommodate bird rods with diameters of Φ30-Φ50 mm. In this embodiment, two reserved holes 21 are opened, with diameters of Φ30 mm and Φ40 mm, respectively. A handle 3 is also provided on the top of the core-pulling component 2. The handle 3 is made of metal and is integrally cast and fixed with the core-pulling component 2 for easy installation and disassembly of the core-pulling component 2. In this embodiment, a 3mm thick Q235 steel plate is wrapped around the periphery of the fixed base 1 and the core-pulling component 2, as well as the inner wall of the accommodating cavity 11, thereby increasing the overall strength.
[0021] This utility model prefabricates the fixed base 1 and the core-pulling component 2 that matches the fixed base 1 in the factory. During installation, these components are transported directly to the construction site. A deep pit is pre-dug to bury the fixed base 1, which is then placed inside. The core-pulling component 2 is then placed into the receiving cavity 11, and the area around the fixed base 1 is filled with soil. Finally, the bird net pole is inserted into the pre-drilled hole 21. This utility model features a streamlined overall structure. After replacing the bird net pole, the dust accumulated in the pre-drilled hole 21 only needs to be cleaned by disassembling and cleaning the core-pulling component 2, reducing maintenance frequency and time and improving maintenance efficiency. It also allows for the reuse of the bird net pole foundation, improving resource utilization. Factory prefabrication reduces on-site construction time and improves construction efficiency.
[0022] Preferably, the core-pulling component 2 is composed of two symmetrically joined inner cores, each precast from C30 plain concrete. Several semi-circular grooves 211 are formed on opposite sides of each inner core along the vertical direction, with two corresponding grooves 211 fitting together to form a pre-drilled hole 21. A handle 3 is fixed to the top of each inner core for easy handling. The surface of each inner core in contact with the inner wall of the receiving cavity 11 is coated with a special insulating oil layer. This insulating oil layer uses metal anti-rust oil to improve the lubrication between the inner core and the receiving cavity 11, while preventing rust and ensuring smooth assembly and reliable connection between the core-pulling component 2 and the fixed base 1. In this embodiment, the core-pulling component 2 is set in separate parts, making it more convenient and faster to replace the bird net pole and clean the pre-drilled hole 21 later.
[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
