Description

Technical Field

[0001] This invention belongs to the field of antenna technology, specifically relating to a mast intelligent monitoring insulation base device. Background Technology

[0002] A single-tower umbrella-shaped longwave transmitting antenna mainly consists of a mast over 200 meters high and a top wire load. The mast and top load must be insulated from the ground. The mast is tall and heavy. The insulating base device, through a ceramic composite structure, insulates the mast from the ground and supports the weight of the entire mast. It is the most critical support structure of the entire antenna, affecting the safety and reliability of the entire mast, and ultimately affecting the antenna's function and radiation performance. Therefore, the design of the mast's insulating base is a key factor in the success or failure of a longwave transmitting antenna.

[0003] Longwave antennas typically consist of a mast over 250 meters high and a top wire load. The mast and top load must be insulated from the ground, and the base of the mast must be designed with a structural device that can meet both the requirements of heavy load capacity and electrical insulation, ensuring the safety, reliability, and electrical insulation performance of the entire mast.

[0004] Currently, the existing mast base insulation method mainly uses a cylindrical insulator to directly support the bottom of the mast. The bottom of the insulator is connected to the ground, and the upper part is connected to the bottom of the mast through a sliding embedded plate groove structure, thereby achieving insulation between the mast and the ground. The application scenario is medium wave broadcast television towers, whose masts are low in height and weight, all below 150 meters, with low structural load-bearing capacity and poor safety.

[0005] Currently, the insulation of mast bases is typically addressed using a single columnar insulator support. This approach suffers from issues such as low structural load-bearing capacity, poor bending and shear resistance at the base, and compromised safety and stability. The main drawbacks are:

[0006] 1. The bottom insulation structure has low load-bearing capacity and cannot meet the bottom insulation requirements of ultra-high and large-tonnage mast structures;

[0007] 2. Individual insulators have poor safety and a low safety factor;

[0008] 3. The mast base has poor resistance to bending, shearing, and overturning. After the mast undergoes displacement and deformation, the column insulator is prone to overturning. Summary of the Invention

[0009] To overcome the shortcomings of existing technologies, this invention provides an intelligent monitoring and insulation base device for masts, comprising an inverted conical intelligent monitoring spherical meshing structure, a balance body, a rain cover, a double-differentiated spherical meshing structure, and base insulators. The inverted conical intelligent monitoring spherical meshing structure concentrates the overall downward pressure of the mast onto the spherical surface, and an internal pressure sensor monitors the overall downward pressure of the mast. The balance body has a trident structure, with the inverted conical intelligent monitoring spherical meshing structure connected to the upper part, and three double-differentiated spherical meshing structures evenly distributed at the lower part. This divides the downward pressure transmitted by the inverted conical intelligent monitoring spherical meshing structure into three equal parts, which are ultimately transmitted to the ground through the three base insulators connected in parallel. The rain cover is installed on the balance body to prevent rain and snow from adhering to the base insulators, thereby reducing their insulation performance. This invention solves the problems of load-bearing capacity and insulation at the bottom of long-wave antenna mast structures, achieving more accurate downward pressure transmission and a larger rotation range, thus improving the overall safety and reliability of the mast.

[0010] The technical solution adopted by this invention to solve its technical problem is as follows:

[0011] A mast intelligent monitoring insulation base device includes an inverted conical intelligent monitoring spherical meshing structure, a balance body, a rain cover, a double heterospherical meshing structure, and a base insulator;

[0012] The inverted conical intelligent monitoring spherical meshing structure concentrates the overall downward pressure of the mast onto the spherical surface, and an internal pressure sensor monitors the overall downward pressure of the mast. The balancing body is a trident structure, with the inverted conical intelligent monitoring spherical meshing structure connected to the upper part of the balancing body, and three double-different spherical meshing structures evenly distributed at the lower part. This divides the downward pressure transmitted by the inverted conical intelligent monitoring spherical meshing structure into three equal parts, and finally transmits the pressure to the ground through the structure of three base insulators connected in parallel.

[0013] The rain cover is installed on the balance body to prevent rain and snow from adhering to the base insulator, thereby reducing the insulation performance of the insulator.

[0014] Preferably, the inverted conical intelligent monitoring spherical meshing structure includes a trident-shaped conical support, a cylindrical pressure sensor, and a disc-shaped spherical body; the trident-shaped conical support includes a cylindrical body, which serves as the main part bearing the downward pressure, and a cylindrical pressure sensor is installed inside the cylindrical body to transmit the pressure value to the display terminal in real time through a wireless transmission module; trident-shaped reinforcing ribs radiate outwards in three directions from the cylindrical body as the center.

[0015] Preferably, the trident-shaped reinforcing rib includes one radial main rib, two secondary ribs, and one transverse rib.

[0016] Preferably, the balancing body includes an upper base plate and a lower base plate, with three sets of trident-shaped reinforcing ribs evenly distributed between the upper and lower base plates, and three double-spherical meshing structures evenly distributed below the reinforcing ribs.

[0017] Preferably, the double spherical meshing structure includes three sets of concave bodies and convex bodies;

[0018] Preferably, the disc-shaped spherical body transmits the mast pressure to the center of the balance body, dividing the downward pressure into three equal parts, so that the force transmission is distributed from the mast centerline to three axes. The pressure on a single base insulator is reduced by the parallel connection, and insulation from the ground is achieved. The three axes are evenly distributed on a circumference with a diameter of 1 meter, which can withstand a maximum horizontal force of 100kN at the mast base, improving the bending, shearing and overturning resistance of the mast base.

[0019] Preferably, the radius of curvature of the disc-shaped spherical body is 0.95 times that of the concave spherical body, and the maximum deviation of the concentricity of the mast's central axis during mast installation is 0.05R.

[0020] Preferably, the base insulator is a conical cylindrical structure.

[0021] Preferably, the base insulator includes a steel top cover, an insulator, and a steel base; the insulator is a ceramic component made of aluminum oxide, which serves as an electrical insulator and a load-bearing component.

[0022] The beneficial effects of this invention are as follows:

[0023] This invention solves the problems of load-bearing capacity and insulation at the base of long-wave antenna masts, achieving insulation of ultra-high masts over 250 meters from the ground; it can withstand 10,000 kN of vertical pressure and 100 kN of horizontal shear force; the two-stage spherical meshing structure and the balancing body structure eliminate the bending moment effect of the mast as a whole on the base structure, achieving more precise downward pressure transmission and a larger rotation range; thus improving the overall safety and reliability of the mast. Simultaneously, real-time monitoring by pressure sensors ensures that the mast's load-bearing state always operates under safe and reliable conditions. Attached Figure Description

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0033] The design scheme adopted in this invention is as follows: The intelligent monitoring and insulating base device for the mast adopts a two-stage meshing insulation structure, including an inverted conical intelligent monitoring spherical meshing structure, a balance body, a rain cover, a double-differentiated spherical meshing structure, and base insulators. This device uses the inverted conical intelligent monitoring spherical meshing structure to concentrate the overall downward pressure of the mast on the spherical surface, with an internal pressure-bearing pressure sensor monitoring the overall downward pressure of the mast. A trident-shaped balance body structure is designed, with the upper part connected to the inverted conical intelligent monitoring spherical meshing structure and three evenly distributed double-differentiated spherical meshing structures at the bottom. This divides the downward pressure transmitted by the conical structure into three equal parts, and finally transmits the pressure to the ground through the parallel structure of the three base insulators.

[0034] The base insulator is made of porcelain, which ensures the load-bearing capacity while insulating the mast from the ground.

[0035] This design method improves the bending moment resistance at the base of the mast and the load-bearing capacity of the insulators, preventing large bending moments from being generated in the mast root structure under external lateral loads, thus enhancing the safety and reliability of the entire structure.

[0036] Example:

[0037] like Figure 1 The diagram shows the overall structure of the mast and the location of the insulating base on the mast. The mast typically consists of a mast tower 4 and multiple layers of fiber ropes 3. The insulating base 2 is located at the bottom of the mast, providing support and insulating the mast tower from the ground.

[0038] like Figure 2The diagram shows the overall layout of the intelligent monitoring insulating base. The mast 4 is connected to the insulating base by bolts. The insulating base consists of an inverted conical intelligent monitoring spherical meshing structure 15, a balance body 14, a double heterospherical meshing structure 13, a rain cover 12, and a base insulator 11, and is installed on the ground concrete foundation 10.

[0039] like Figure 3 As shown, the inverted conical intelligent monitoring spherical meshing structure 15 consists of a trident-shaped conical support body 17, a cylindrical pressure sensor 18, and a disc-shaped spherical body 16. A cylindrical main body is arranged at the center of the conical support body, serving as the main part to bear the downward pressure. The pressure sensor is installed inside the cylindrical main body, and the pressure value can be transmitted to the display terminal in real time through a wireless transmission module. Trident-shaped reinforcing ribs radiate from the center of the cylindrical body in three directions. The trident-shaped reinforcing ribs include one radial main rib, two secondary ribs, and one transverse rib. This distribution method can effectively bear the downward pressure and bending moment, and ultimately allow the weight of the mast to be transferred and concentrated on the meshing spherical surface.

[0040] like Figure 4 As shown, the radii of curvature of the meshing spherical surfaces are different. The radius of curvature of the disc-shaped spherical body 16 is 0.95 times that of the concave body 20. During mast installation, the maximum deviation of the mast's central axis concentricity is 0.05R. Figure 3 As shown in the diagram above, after the disc-shaped spherical surface enters the concave spherical surface, the concave spherical surface undergoes horizontal sliding under the pressure of the mast's own weight. This allows the mast to adaptively adjust its vertical concentricity, ensuring that its central axes coincide and guaranteeing stable force transmission. When the central axes coincide, the two spherical surfaces engage in frictional contact under pressure in local areas, as shown in the diagram. Figure 3 As shown in the middle figure, this effectively ensures the bearing contact surface; simultaneously, the meshing spherical surface can rotate 3° in three directions with the contact center as the vertex, eliminating the bending moment on the bottom structure when the mast is subjected to external horizontal loads, such as... Figure 3 As shown in the image below.

[0041] like Figure 5 As shown, the three sets of concave bodies 20 and convex bodies 21 form a double heterospherical meshing structure. Figure 6 As shown, the balance body consists of upper and lower base plates, three sets of trident-shaped reinforcing ribs evenly distributed in the middle, secondary ribs extending and intersecting, and three double heterospherical meshing structures evenly distributed below the reinforcing ribs.

[0042] The disc-shaped spherical body transmits the pressure of the mast to the center of the balance body, dividing the downward pressure into three equal parts. This disperses the force transmission from the mast centerline to three axes, reducing the pressure on individual insulators through parallel connection and achieving insulation from the ground. The three axes are evenly distributed on a circumference with a diameter of 1 meter, which can withstand a maximum horizontal force of 100kN at the mast base, improving the mast base's resistance to bending, shearing, and overturning.

[0043] The rain cover 12 is installed on the balance body. Its main function is to prevent rain and snow from adhering to the insulator, thereby reducing the insulation performance of the insulator.

[0044] like Figure 7 The diagram shown is a schematic of the base insulator 11. The insulator is a conical cylindrical structure, comprising a steel top cover 22, an insulator 23, and a steel base 24. The insulator is a ceramic component made of aluminum oxide, which serves as an electrical insulator and a load-bearing component.

[0045] When the three base insulators, the balance body, and the two-stage meshing structure form an insulation device, the entire structure provides load-bearing support for the mast structure and insulates it from the ground. The three base insulators improve the overall safety factor of the mast, increase the load-bearing capacity at the base, and achieve base insulation. The two-stage spherical meshing structure allows the mast to rotate with three degrees of freedom around the center of the inverted conical spherical surface and allows for limited horizontal slippage, eliminating the bending moment at the base of tall masts. The triangular distribution of the three insulators reduces the shear force at the base caused by mast tilting. Simultaneously, the built-in pressure sensor monitors the pressure under the mast in real time. This invention enables insulation of ultra-high masts for long-wave antennas, improving safety and stability.
