Description

Technical Field

[0001] This utility model relates to the field of two-dimensional phased array radar installation technology, specifically a modular installation and fixing device for two-dimensional phased array radar. Background Technology

[0002] In field surveillance applications, two-dimensional phased array radars require rapid deployment and precise positioning, thus necessitating stable and reliable installation and fixing solutions.

[0003] Existing technology, such as the publication number "CN215764374U", discloses a tripod structure and radar system for low-altitude search radar, including a tripod, a vertical rod, a counterweight plate, and a stabilizing plate. The bottom surface of the middle part of the tripod is connected to the vertical rod by bolts. The counterweight plate is located on the outer surface of the vertical rod, and the stabilizing plate is located on the bottom surface of the vertical rod. This tripod structure and radar system for low-altitude search radar solves the problem that existing radar tripods are prone to tipping over due to unstable center of gravity when the external wind force is strong, as the radar surface experiences greater wind resistance.

[0004] However, the tripod structure used for low-altitude search radar has the following problems: 1) When deploying radar equipment in the field, adjusting the height can reduce the radar cross-section, but the height of this tripod is fixed and difficult to adjust; 2) The radar's facing plane can only rotate 360 ​​degrees, lacking the ability to receive targets from multiple angles. Therefore, we propose a modular mounting and fixing device for a two-dimensional phased array radar. Utility Model Content

[0005] The purpose of this invention is to solve the problems of difficulty in adjusting the height and the limited range of acceptable angles, and to provide a modular installation and fixing device for a two-dimensional phased array radar.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A modular mounting and fixing device for a two-dimensional phased array radar includes a tripod outer rod, an inner tripod rod slidably mounted on the bottom inner wall of the outer tripod rod, a support foot rotatably mounted on the bottom of the inner tripod rod, a limit plate rotatably mounted on the opposite outer wall of the outer tripod rod, a fastening device at the top of the inner tripod rod, and an adjustment device at the top of the outer tripod rod. The fastening device includes several inner plates, several anti-slip pads, a tensioner, and an anti-slip groove. The inner plates are arranged in groups of three, with each group of inner plates fixedly mounted on the bottom of the outer tripod rod, and each group of inner plates has a threaded groove on its outer wall. The anti-slip pads are arranged in groups of three, with each group of anti-slip pads fixedly mounted on the inner wall of each group of inner plates near the inner tripod rod. The tensioner is threadedly connected to the outer wall of the threaded groove of each group of inner plates, and the anti-slip groove is formed on the outer wall of the inner tripod rod.

[0008] Preferably, several of the inner cladding plates have a certain degree of toughness, several of the anti-slip pads are in contact with the outer wall of the anti-slip groove on the inner rod of the tripod, and several of the anti-slip pads are made of rubber. The tensioner is used to control the contraction of each group of inner cladding plates.

[0009] Preferably, the adjustment device includes a mounting plate, shock-absorbing pads, a mounting platform, a universal adjusting head, an adjusting ball, a straight rod, a fixing plate, a sliding cavity, an anti-slip strip, a limiting seat, a threaded rod, and a torsion block. The mounting plate is fixedly installed on the top of the outer rod of the tripod. The shock-absorbing pads are disposed on the top of the four corners of the mounting plate. The mounting platform is fixedly installed on the top of the shock-absorbing pads by bolts. The universal adjusting head is fixedly installed on the top of the mounting platform. The adjusting ball is rotatably installed on the inner wall of the universal adjusting head. The straight rod is fixedly installed on the top of the adjusting ball. The fixing plate is fixedly installed on the top of the straight rod. The sliding cavity is formed on the inner wall between the universal adjusting head and the adjusting ball. The anti-slip strip is slidably installed on the inner wall of the sliding cavity. The limiting seat is fixedly installed on the side of the anti-slip strip away from the adjusting ball. The threaded rod passes through and is threadedly connected to the inner wall of the universal adjusting head. The torsion block is fixedly installed on the end of the threaded rod away from the anti-slip strip.

[0010] Preferably, the surface of the adjusting ball is provided with an anti-slip groove, the anti-slip strip is made of rubber, and the threaded rod is rotatably installed on the inner wall of the limiting seat.

[0011] Preferably, the adjusting ball has a three-dimensional adjustment function, with an azimuth adjustment range greater than or equal to 360 degrees, a pitch adjustment range from 0 degrees to 90 degrees, and an adjustment accuracy less than or equal to 0.1 degrees.

[0012] Preferably, the shock-absorbing pad is made of high-damping material, the fixing plate is made of lightweight and high-strength aluminum alloy, and the surface of the fixing plate is provided with precision positioning holes.

[0013] By employing the above technical solution, this utility model provides a modular mounting and fixing device for a two-dimensional phased array radar. It possesses at least the following beneficial effects:

[0014] (1) This utility model achieves a firm lock between the inner and outer rods of the tripod by tightening the tensioner with a threaded fastener, effectively preventing it from sliding or loosening during operation and ensuring that the two-dimensional phased array radar equipment remains stable at the adjusted height.

[0015] (2) This utility model achieves all-round precision adjustment of a two-dimensional phased array radar through the cooperation of a universal adjustment head and an adjustment ball. The adjustment ball can rotate freely in the universal adjustment head, providing a three-dimensional range of azimuth greater than or equal to 360 degrees and elevation from 0 degrees to 90 degrees, meeting complex detection requirements. When the angle is adjusted to the correct position, the rotating torsion block drives the threaded rod, so that the rubber anti-slip strip is tightly embedded in the anti-slip groove of the adjustment ball (accuracy less than or equal to 0.1 degrees), achieving high-precision and reliable locking, effectively preventing deviation under external interference. At the same time, combined with the high-damping shock-absorbing pads at the bottom of the mounting platform, it can effectively isolate the vibration of the field environment and ensure the stability of radar signal reception.

[0023] 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.

[0024] Example 1

[0025] A modular mounting and fixing device for a two-dimensional phased array radar, such as Figures 1-4 As shown, the tripod includes an outer tripod pole 1, an inner tripod pole 2 slidably mounted on the bottom inner wall of the outer tripod pole 1, a support foot 3 rotatably mounted on the bottom of the inner tripod pole 2, a limit plate 4 rotatably mounted on the opposite outer wall of the outer tripod pole 1, a fastening device 5 at the top of the inner tripod pole 2, and an adjustment device 6 at the top of the outer tripod pole 1. The fastening device 5 includes several inner plates 51, several anti-slip pads 52, a tensioner 53, and an anti-slip groove 5. 4. Several inner covering plates 51 are arranged in groups of three. Each group of inner covering plates 51 is fixedly installed at the bottom of the outer pole 1 of the tripod. The outer wall of each group of inner covering plates 51 is provided with a threaded groove. Several anti-slip pads 52 are arranged in groups of three. Each group of anti-slip pads 52 is fixedly installed on the inner wall of each group of inner covering plates 51 near the inner pole 2 of the tripod. Tensioner 53 is threadedly connected to the outer wall of the threaded groove of each group of inner covering plates 51. Anti-slip groove 54 is provided on the outer wall of the inner pole 2 of the tripod.

[0026] Several inner cladding plates 51 have a certain degree of toughness, several anti-slip pads 52 are in contact with the outer wall of the anti-slip groove 54 on the inner rod 2 of the tripod, and the several anti-slip pads 52 are made of rubber. The tensioner 53 is used to control the contraction of each set of inner cladding plates 51.

[0027] When using the modular installation and fixing device for a two-dimensional phased array radar, the height of the radar equipment needs to be adjusted according to the target and surrounding environment when it is deployed in the field. Therefore, the outer rod 1 of the tripod is opened to the maximum opening length of the limiting plate 4, and then the inner rod 2 of the tripod, together with the support leg 3, is pulled outward from the inner wall of the outer rod 1 to the required height. After the support leg 3 is supported on the ground, the tensioner 53 is rotated downward along the threaded groove of the inner plate 51. After the tensioner 53 rotates downward, it pulls the three inner plates 51 inward and closes them together. The three inner plates 51 drive the three anti-slip pads 52 to pull inward and close together. The three anti-slip pads 52 will then adhere to the outer wall of the anti-slip groove 54 of the inner rod 2 of the tripod. The tensioner 53 is tightened by threads, thereby achieving a secure lock between the inner rod 2 and the outer rod 1 of the tripod, effectively preventing them from slipping or loosening during operation, and ensuring that the two-dimensional phased array radar equipment remains stable at the adjusted height.

[0028] Example 2

[0029] This embodiment, based on embodiment 1, specifically includes the following:

[0030] like Figure 3 and Figure 5As shown, the adjustment device 6 includes a mounting plate 61, shock-absorbing pads 62, a mounting platform 63, a universal adjusting head 64, an adjusting ball 65, a straight rod 660, a fixing plate 661, a sliding cavity 67, an anti-slip strip 68, a limit seat 69, a threaded rod 610, and a torsion block 611. The mounting plate 61 is fixedly installed on the top of the outer rod 1 of the tripod. The shock-absorbing pads 62 are located on the top of the four corners of the mounting plate 61. The mounting platform 63 is fixedly installed on the top of the shock-absorbing pads 62 by bolts. The universal adjusting head 64 is fixedly installed on the top of the mounting platform 63. The adjusting ball 65... The universal adjusting head 64 is rotatably mounted on the inner wall. The straight rod 660 is fixedly mounted on the top of the adjusting ball 65. The fixing plate 661 is fixedly mounted on the top of the straight rod 660. The sliding cavity 67 is opened on the inner wall between the universal adjusting head 64 and the adjusting ball 65. The anti-slip strip 68 is slidably mounted on the inner wall of the sliding cavity 67. The limiting seat 69 is fixedly mounted on the side of the anti-slip strip 68 away from the adjusting ball 65. The threaded rod 610 passes through and is threadedly connected to the inner wall of the universal adjusting head 64. The torsion block 611 is fixedly mounted on the end of the threaded rod 610 away from the anti-slip strip 68.

[0031] The surface of the adjusting ball 65 is provided with anti-slip groove 2, the anti-slip strip 68 is made of rubber, and the threaded rod 610 is rotatably installed on the inner wall of the limit seat 69.

[0032] The adjustment ball 65 has a three-dimensional adjustment function, with an azimuth adjustment range of 360 degrees or more, a pitch adjustment range of 0 to 90 degrees, and an adjustment accuracy of less than or equal to 0.1 degrees.

[0033] The shock-absorbing pad 62 is made of high-damping material, and the fixing plate 661 is made of lightweight and high-strength aluminum alloy. The surface of the fixing plate 661 is provided with precision positioning holes.

[0034] In use, the modular installation and fixing device for a two-dimensional phased array radar according to this utility model fixes the two-dimensional phased array radar equipment to the fixing plate 661 with bolts. When it is necessary to adjust the receiving surface of the two-dimensional phased array radar equipment in multiple directions, the fixing plate 661 is rotated. The fixing plate 661 drives the straight rod 660 to rotate. The straight rod 660 drives the adjusting ball 65 to rotate on the inner wall of the universal adjusting head 64. After adjusting to the required adjustment angle, the torsion block 611 is rotated. The torsion block 611 drives the threaded rod 610 to rotate. The threaded rod 610 drives the limiting seat 69 to move inward. The limiting seat 69 drives the anti-slip strip 68 to slide on the inner wall of the sliding cavity 67 of the universal adjusting head 64 towards the adjusting ball 65. After being squeezed, the rubber material of the anti-slip strip 68 will be embedded in the anti-slip groove of the adjusting ball 65, thereby completing the fixing of the adjusted angle. Through the cooperation of the universal adjustment head 64 and the adjustment ball 65, the all-round precision adjustment of the two-dimensional phased array radar is realized. The adjustment ball 65 can rotate freely within the universal adjustment head 64, providing a three-dimensional range of azimuth greater than or equal to 360 degrees and elevation from 0 degrees to 90 degrees, meeting complex detection requirements. When the angle is adjusted to the correct position, the rotating torsion block 611 drives the threaded rod 610, so that the rubber anti-slip strip 68 is tightly embedded in the anti-slip groove of the adjustment ball 65 (accuracy less than or equal to 0.1 degrees), achieving high-precision and reliable locking, effectively preventing deviation under external interference. At the same time, combined with the high-damping shock-absorbing pad 62 at the bottom of the mounting platform 63, it can effectively isolate the vibration of the field environment and ensure the stability of radar signal reception.
