Description

Technical Field

[0002] A radar mast is a key support structure that carries radar equipment, providing a stable installation platform for radar antennas, signal processing equipment, and other devices. Radar masts are widely used in ships, aerospace, ground radar stations, and other scenarios.

[0003] The radar mast is constructed from angle steel and steel pipes welded into a lattice frame, including an antenna mounting platform, internal equipment compartments, cables, and other auxiliary structures. The radar mast can withstand the weight of the radar itself, wind loads, and vibrations caused by the movement of ships or vehicles. The load is distributed to the base through the truss structure to maintain the accuracy of radar detection.

[0004] When a radar mast is in operation, it will be subjected to vertical forces such as its own weight, equipment load, and external wind force, which will generate an overturning moment. This can easily lead to stress concentration at the mast connection points, resulting in swaying or deformation of the mast.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1 to 6As shown, a stable radar mast structure according to an embodiment of the present invention includes a mast 1; a plurality of support plates 12 are provided at the bottom of the mast 1; a first support rod 10 is installed at the top of the mast 1; a plurality of second support rods 11 are installed in the middle of the first support rod 10; an adjustment assembly 2 and a limiting assembly 4 are installed in the middle of the mast 1 and the first support rod 10; a base plate 15 is fixedly connected to the bottom of the mast 1; a mounting rod 13 is fixedly connected to the bottom of the base plate 15; a plurality of positioning blocks 14 are fixedly connected to the middle of the mounting rod 13; the plurality of positioning blocks 14 are equidistantly distributed; and a mounting plate 16 is installed at the bottom of the mounting rod 13. A non-slip pad 18 is fixedly connected to the middle of the mounting plate 16; a positioning groove 103 is formed in the middle of the mounting plate 16 and the non-slip pad 18; multiple reinforcing rods 17 are fixedly connected to the outer wall of the mounting plate 16; multiple mounting grooves 19 are formed in the middle of the reinforcing rods 17; multiple connecting rods 101 are installed in the middle of the mounting plate 16 and the bottom plate 15; fastening nuts 102 are installed at both ends of the connecting rods 101; a flow guide assembly 3 is provided in the middle of the first support rod 10; during operation, when the mast 1 is installed on the hull, the mounting rod 13 and the positioning block 14 penetrate the deck, and the bottom plate 15 is in contact with the deck, from Inside the deck, the mounting plate 16 is installed at the bottom of the mounting mast 13. At this point, it is tightly fitted to the bottom of the deck via anti-slip pads 18 and positioned according to the positioning slots 103 corresponding to the positioning blocks 14. Multiple connecting rods 101 pass through the mounting plate 16 and are fastened to the middle of the base plate 15 using fastening nuts 102, clamping the deck between the base plate 15 and the mounting plate 16. Simultaneously, multiple reinforcing rods 17 are fitted against the bottom of the deck and then installed on the bottom of the deck via fastening bolts through the mounting slots 19. When the mast 1 sways, pressure is applied to the deck through the multiple mounting slots 19 to maintain stability. To maintain the stability of mast 1, when passing through height-restricted areas or when the height of mast 1 needs to be adjusted, the entire structure is adjusted by adjusting component 2. When mast 1 is subjected to wind and wave impacts, a bending moment is generated at the bottom. Through the tight fit between the bottom plate 15 and the mounting plate 16, the horizontal force can be converted into shear force in the deck plane. The rigidity of the overall deck structure is used to resist the swaying or deformation of mast 1 caused by wind, effectively resisting bending moment and making it more stable in wind, waves or vibration environments, reducing the swaying of the bottom of mast 1 or the loosening of connecting parts.

[0026] like Figure 3 and Figure 4As shown, the adjustment assembly 2 includes an adjustment groove 21; the adjustment groove 21 is located in the middle of the mast 1; a motor 22 is installed at the bottom of the adjustment groove 21; a lead screw 23 is fixedly connected to the output end of the motor 22; an adjustment nut 24 is installed in the middle of the lead screw 23; an adjustment rod 25 is fixedly connected to the top of the adjustment nut 24; the adjustment rod 25 is slidably connected to the middle of the adjustment groove 21; the end of the adjustment rod 25 is fixedly connected to the bottom of the first support rod 10; multiple positioning rods 26 are fixedly connected to the bottom of the first support rod 10; multiple sliding grooves 27 are provided in the middle of the mast 1; the positioning rods 26 are slidably connected to the middle of the sliding grooves 27; during operation, when adjusting the height of the mast 1, the motor 22 is first controlled by the control system. When activated, the output of motor 22 drives lead screw 23 to rotate. When lead screw 23 rotates, adjusting nut 24 drives adjusting rod 25 to slide up and down in the middle of adjusting groove 21. As adjusting rod 25 moves, multiple positioning rods 26 slide in the middle of sliding groove 27, thereby reinforcing the support of adjusting rod 25. With the above structure, when a ship passes through a height-restricted bridge, mast 1 can be quickly lowered to a safe height, reducing the time wasted on deceleration or changing course, effectively improving passage efficiency. It can adjust the radar detection range according to the height of surrounding buildings, reducing signal obstruction. Lowering mast 1 to the lowest height can reduce the deformation or capsizing of mast 1 caused by excessive wind force in strong winds.

[0027] like Figure 2 and Figure 6 As shown, the flow guiding assembly 3 includes multiple sets of fixed rods 31; each set of fixed rods 31 is located in the middle of the second support rod 11; two flow guiding plates 32 are hinged to the end of each set of fixed rods 31; two sets of connecting ropes 33 are fixed to the end of the flow guiding plates 32; a rotating cylinder 34 is rotatably connected to the middle of the first support rod 10; a gear ring 35 is fixed to the bottom of the rotating cylinder 34; a driver 36 is installed in the middle of the first support rod 10; a gear 37 is fixed to the output end of the driver 36; the gear 37 and the gear ring 35 are meshed; the ends of the multiple sets of connecting ropes 33 are fixed to the middle of the rotating cylinder 34; during operation, when strong winds disturb the first support rod 10, the driver 36 is activated, and the driver 36 outputs... The end drives the gear 37 to rotate, and the rotation of the gear 37 causes the gear ring 35 to drive the rotating cylinder 34 to rotate. When the rotating cylinder 34 rotates, multiple connecting ropes 33 are unwound. A torsion spring is provided between the guide plate 32 and the fixed rod 31. When the connecting rope 33 releases the guide plate 32, the torsion spring unfolds the guide plate 32, and the guide plate 32 directs the strong wind. Through the above structure, the airflow is guided to flow smoothly along the surface of the guide plate 32 in strong wind conditions, blocking strong winds and sand, reducing the formation of separation vortices in the airflow at the top of the first support rod 10, thereby reducing the wind resistance coefficient and reducing the fatigue stress of the main structure of the mast 1. After the guide plate 32 is folded, it is tightly attached to the top of the first support rod 10, reducing the space occupied.

[0028] like Figure 4 and Figure 5As shown, the limiting assembly 4 includes a limiting groove 41; the limiting groove 41 is formed at the top of the mast 1; the limiting groove 41 is formed between two positioning rods 26; a switch 42 is installed in the middle of the limiting groove 41; a limiting block 43 is fixedly connected to the bottom of the first support rod 10; the limiting block 43 corresponds to the position of the limiting groove 41; a spring 44 is fixedly connected to the middle of the limiting block 43; a buffer plate 45 is fixedly connected to the end of the spring 44; during operation, when adjusting the height of the mast 1, as the adjusting rod 25 moves down, the first support rod 10 continuously moves towards the top of the mast 1, and the buffer plate 45 first contacts the end of the switch 42. With elastic contact, as the first support rod 10 continues to move downward, the spring 44 contracts, and the buffer plate 45 enters the middle of the limiting block 43. After the switch 42 is pressed, the motor 22 stops immediately, thereby reducing the excessive impact between the first support rod 10 and the mast 1. Through the above structure, when the bottom of the first support rod 10 descends, the buffer plate 45 is compressed and undergoes elastic deformation, converting the rigid impact into flexible buffering. When the buffer plate 45 is compressed and deformed to a preset threshold, the bottom switch 42 is triggered to cut off the power to the motor 22, realizing linkage shutdown and reducing the overshoot generated between the first support rod 10 and the mast 1.

[0029] like Figure 4 As shown, a heat-conducting rod 5 is installed at the bottom of the regulating groove 21; multiple through holes 51 are opened in the mast 1; the multiple through holes 51 are opened at the corresponding positions of the motor 22; during operation, the internal components of the motor 22 will generate heat, which is transferred to the surface of the mast 1 through the heat-conducting rod 5. The heat inside the regulating groove 21 flows with the external airflow through the through holes 51, thereby reducing the overheating of the motor 22 during operation. The above structure can effectively reduce the heat accumulation inside the motor 22, form strong convection between the heat and the external airflow, reduce the operating temperature of the motor 22, and keep the motor 22 at an appropriate temperature.

[0030] like Figure 6 As shown, a protective box 6 is fixedly connected to the middle of the first support rod 10; the protective box 6 is fixed to the outside of the gear ring 35 and the drive 36; the rotating cylinder 34 passes through the top of the protective box 6; during operation, the protective box 6 protects the drive 36, gear ring 35 and gear 37, reducing external dust and rainwater erosion. Through the above structure, sand, gravel, bird droppings and other foreign objects can be effectively blocked from adhering to the surface of the drive 36, gear 37 and gear ring 35 during navigation, reducing wear or jamming problems between the gear ring 35 and gear 37.

[0031] like Figure 6 As shown, the multiple guide plates 32 are made of lightweight plastic sheets. During operation, the density of the lightweight plastic sheets lowers the center of gravity of the top of the first support rod 10. The above structure can effectively reduce vibration and stress concentration caused by wind load or ship swaying, and improve the overall structural stability.

[0032] During operation, when mast 1 is installed on the hull, mounting rod 13 and positioning block 14 penetrate the deck, and bottom plate 15 is fitted against the deck. Mounting plate 16 is installed from inside the deck at the bottom of mounting rod 13. At this time, anti-slip pads 18 are used to tightly fit against the bottom of the deck, and positioning slots 103 are used to position the corresponding positioning block 14. Multiple connecting rods 101 pass through the mounting plate 16 and are fastened to the middle of bottom plate 15 with fastening nuts 102, clamping the deck between bottom plate 15 and mounting plate 16. Simultaneously, multiple reinforcing rods 17 are fitted against the bottom of the deck, and then fastening bolts are used to install the reinforcing rods 17 onto the bottom of the deck through mounting slots 19. When mast 1... When swaying occurs, pressure is applied to the deck through multiple mounting slots 19 to maintain the stability of mast 1. When passing through height-restricted areas or when the height of mast 1 needs to be adjusted, the entire mast is adjusted through the adjustment assembly 2. When adjusting the height of mast 1, the control system first controls the motor 22 to start, causing the output end of the motor 22 to drive the lead screw 23 to rotate. When the lead screw 23 rotates, the adjusting nut 24 drives the adjusting rod 25 to slide up and down in the middle of the adjusting slot 21. As the adjusting rod 25 moves, multiple positioning rods 26 slide in the middle of the sliding groove 27, thereby reinforcing the support of the adjusting rod 25. When encountering strong winds that disturb the first support rod 10... When activated, the control driver 36 turns on, and the output of the driver 36 drives the gear 37 to rotate. The rotation of the gear 37 causes the gear ring 35 to drive the rotating drum 34 to rotate. When the rotating drum 34 rotates, multiple connecting ropes 33 are unwound. A torsion spring is provided between the guide plate 32 and the fixed rod 31. When the connecting ropes 33 loosen the guide plate 32, the torsion spring unfolds the guide plate 32, which then guides the strong wind. When adjusting the height of the mast 1, as the adjusting rod 25 moves down, the first support rod 10 continuously moves towards the top of the mast 1. The buffer plate 45 first makes elastic contact with the end of the switch 42. As the first support rod 10 continues to move down... When the spring 44 retracts, the buffer plate 45 enters the middle of the limit block 43. After the switch 42 is pressed, the motor 22 stops immediately, thereby reducing the excessive impact between the first support rod 10 and the mast 1. During the operation of the motor 22, the internal components of the motor 22 will generate heat. The heat is transferred to the surface of the mast 1 through the heat conduction rod 5. The heat inside the adjustment groove 21 flows with the external airflow through the through hole 51, thereby reducing the overheating of the motor 22 during operation. The driver 36, gear ring 35 and gear 37 are protected by the protective box 6 to reduce the corrosion of external dust and rainwater. The density of the lightweight plastic plate reduces the center of gravity of the top of the first support rod 10.
