Description

Technical Field

[0001] The invention relates to the technical field of radar antenna direction control, and in particular to an antenna direction control device for directional drilling radar. Background Art

[0002] Radar is the transliteration of the English word Radar, which is derived from the abbreviation of radio detection and ranging, meaning "radio detection and ranging", that is, using radio methods to detect targets and determine their spatial positions. Therefore, radar is also called "radio positioning". Radar is an electronic device that uses electromagnetic waves to detect targets. Radar emits electromagnetic waves to illuminate the target and receives its echo, thereby obtaining information such as the distance from the target to the electromagnetic wave emission point, the rate of change of distance (radial velocity), azimuth, and altitude. Radar is a device used to radiate and receive electromagnetic waves and determine its detection direction. When transmitting, the radar must concentrate its energy to radiate the direction that needs to be irradiated; when receiving, it should try to only receive the echo in the detection direction, and at the same time distinguish the azimuth and elevation of the target, or one of the two. Among the three coordinates (azimuth, elevation, and distance) of the target position measured by radar, the measurement of two coordinates (azimuth and elevation) is directly related to the performance of the antenna. Therefore, antenna performance is more important for radar equipment than for other electronic equipment (such as communication equipment).

[0003] There are many types of radar antennas. According to their structural forms, they are mainly divided into two categories: reflector antennas and array antennas. According to the scanning method of the antenna beam, radar antennas can be divided into mechanical scanning antennas, electronic scanning antennas and electromechanical scanning antennas. The reflector antenna consists of a reflector and a radiator. The radiator is also called a feed source, a radiating element, or an illuminator. It radiates electromagnetic waves to the reflector and forms a beam after reflection. Typical reflector antennas are rotating parabolic antennas, cut parabolic antennas, parabolic cylinder antennas, Cassegrain antennas, single pulse antennas, stacked beam antennas, shaped beam antennas, and offset fed antennas. The mechanical scanning antenna drives the antenna to rotate mechanically to achieve two-dimensional scanning of the antenna beam in azimuth and elevation, and the scanning speed is slow. The electronic scanning antenna is fixed, and the two-dimensional scanning of the beam in azimuth and elevation is achieved by controlling the feed phase or working frequency of each radiating unit on the array antenna using electronic technology. The beam scanning speed is very fast. The azimuth scanning of the electromechanical scanning antenna is generally performed by mechanically driving the antenna to rotate, and the elevation scanning is achieved by electronic technology controlling the feeding phase or working frequency of each radiating unit. Therefore, the azimuth scanning is slow, and the elevation scanning is fast. Sometimes the electromechanical scanning antenna is also called a one-dimensional electronic scanning antenna.

[0004] In the prior art, the radar antenna signal receiving direction of directional drilling is fixed. Therefore, when drilling in places with weak signals, it is easy to fail to receive signals, resulting in errors in the drilling direction and affecting the overall progress of the construction.

[0042] Specifically, through the transmission cooperation between the antenna protection component 220 and the driving component 210, the driving component 210 can drive the antenna adjustment component 230 to rotate only after the radar antenna body 236 is exposed to the outside. When the antenna adjustment component 230 is located inside the two antenna protection components 220, the driving component 210 cannot drive the antenna adjustment component 230 to rotate, thereby avoiding the situation where the antenna adjustment component 230 and the antenna protection component 220 collide with each other due to operator misoperation.

[0043] In order to facilitate those skilled in the art to fully understand the specific structure and principle of the driving assembly 210, the driving assembly 210 is further explained. In this embodiment, the driving assembly 210 includes a second servo motor 211, which is installed on the inner wall of the directional drilling mobile trolley 101 by bolts. The output end of the second servo motor 211 is fixedly connected to the first spline shaft 212, and the outer ring movable sleeve of the first spline shaft 212 is provided with a spline sleeve 213.

The bottom end of the guide screw 218 is fixedly installed on the top outer wall of the directional drilling mobile trolley 101, and the top outer ring rotating sleeve of the guide screw 218 is provided with a limiting screw sleeve 219.

[0045] In order to facilitate those skilled in the art to fully understand the specific structure and principle of the antenna protection assembly 220, further description is made on the antenna protection assembly 220. In this embodiment, the antenna protection assembly 220 includes: a support frame 221, the support frame 221 is fixed on the top outer wall of the directional drilling mobile vehicle 101, the inner ring rotating sleeve of the support frame 221 is provided with a first rotating shaft 222, the outer ring fixed sleeve of the first rotating shaft 222 is provided with a radar antenna shield 223 and a first transmission gear 224, and the first transmission gear 224 is meshed with the straight rack 216.

[0046] Specifically, the radar antenna shield 223 can drive the first transmission gear 224 to rotate through the first rotating shaft 222. When the two radar antenna shields 223 are separated, the engagement of the first transmission gear 224 with the straight rack 216 will drive the spline sleeve 213 to move upward. When the two radar antenna shields 223 are merged together, the spline sleeve 213 will move downward.

[0047] In order to facilitate those skilled in the art to fully understand the specific structure and principle of the antenna adjustment assembly 230, the antenna adjustment assembly 230 is further described. In this embodiment, the antenna adjustment assembly 230 includes a fixed base 231 located above the top of the directional drilling mobile trolley 101, and the bottom and top of the fixed base 231 are respectively fixedly connected with a second spline shaft 233 and an antenna support platform 234, the antenna support platform 234 is rotatably sleeved in the top inner ring of the directional drilling mobile trolley 101, and the bottom end of the second spline shaft 233 is plugged with the spline sleeve 213, and the inner ring of the antenna support platform 234 is rotatably sleeved with a second rotating shaft 235, and the ends of the two second rotating shafts 235 close to each other are fixedly connected with a radar antenna body 236.

[0048] Specifically, when the spline sleeve 213 moves upward, the first spline shaft 212 can drive the second spline shaft 233 to rotate in the top inner ring of the directional drilling mobile trolley 101 through the spline sleeve 213, and the fixed base 231 and all structures connected thereto will rotate at the same time.

[0049] In order to facilitate those skilled in the art to fully understand the specific structure and principle of the antenna guide assembly 240, the antenna guide assembly 240 is further described. In this embodiment, the antenna guide assembly 240 includes: a fixed plate 241, a fixed leg 243 is welded to the bottom of the fixed plate 241, and the bottom end of the fixed leg 243 is fixedly connected to the top outer wall of the directional drilling mobile vehicle 101 through bolts; a plurality of arc-shaped racks 242 are fixedly connected to the top of the fixed plate 241, and the arc-shaped racks 242 match the two second transmission gears 237; the fixed plate 241 and the fixed base 231 are both circular, and the diameter of the fixed plate 241 is larger than the diameter of the fixed base 231, and they are located on the same center of the circle.

[0050] Specifically, when the fixed base 231 rotates, the two second transmission gears 237 will rotate above the fixed plate 241, so that when one second transmission gear 237 is engaged with an arc-shaped rack 242, the other second transmission gear 237 will just be disengaged from the corresponding arc-shaped rack 242, so that when the radar antenna body 236 rotates with the second spline shaft 233 as the axis, the radar antenna body 236 will also swing with the second rotating shaft 235 as the axis.

[0051] In order to facilitate those skilled in the art to fully understand the specific structure and principle of the directional drilling mechanism 100, the directional drilling mechanism 100 is further explained. In this embodiment, a slide rail 104 is fixedly installed on the left outer wall of the directional drilling mobile trolley 101, and a first servo motor 105 is fixedly installed on the top of the slide rail 104. A threaded rod 106 is fixedly connected to the output end of the first servo motor 105, and the threaded rod 106 is connected to a mounting plate 107 through a threaded sleeve. Slide blocks 108 are fixedly connected on both sides of the mounting plate 107, and the slide blocks 108 are slidably connected to the slide rail 104; a drilling machine 109 is fixedly sleeved on the inner ring of the mounting plate 107, and an anti-slip plate is fixedly connected to the bottom end of the threaded rod 106; a plurality of pulleys 103 are fixedly connected to the bottom outer wall of the directional drilling mobile trolley 101, a first guide groove 102 is opened on the top outer wall of the directional drilling mobile trolley 101, and a second guide groove 232 is opened at the bottom of the fixed base 231, the second guide groove 232 is adapted to the first guide groove 102, and a ball bearing is arranged between them.

[0052] Specifically, the first servo motor 105 drives the threaded rod 106 to rotate, and the threaded rod 106 drives the mounting plate 107 and the slider 108 to move up and down along the track of the slide rail 104 through the threaded sleeve. Before the mounting plate 107 moves downward, the drilling machine 109 is started to drill holes.

[0053] Working principle: First, the radar antenna shield 223 can drive the first transmission gear 224 to rotate through the first rotating shaft 222. When the two radar antenna shields 223 are separated, the meshing of the first transmission gear 224 and the straight rack 216 will drive the spline sleeve 213 to move upward. When the two radar antenna shields 223 are combined together, the spline sleeve 213 will move downward. When the directional drilling mobile trolley 101 moves over a long distance, the two radar antenna shields 223 are combined together. At this time, when the second servo motor 211 drives the first spline shaft 212 to rotate, the first spline shaft 212 cannot pass through the spline sleeve 21 3 drives the second spline shaft 233 to rotate (the reason is that the two radar antenna shields 223 are combined together, the spline sleeve 213 moves downward, and the second spline shaft 223 is not plugged into the spline sleeve 213). When the directional drilling mobile trolley 101 moves to the predetermined area, the two combined radar antenna shields 223 are opened, and the spline sleeve 213 is driven to move upward, so that the spline sleeve 213 is sleeved on the outer rings of the first spline shaft 212 and the second spline shaft 233. At this time, the second servo motor 211 is started, and the first spline shaft 212 connected thereto can be driven to rotate by the second servo motor 211, and the first spline shaft 212 will drive the spline sleeve 2 13 is rotated, the spline sleeve 213 cannot drive the connecting arm 215 to rotate through the bearing 214, and the spline sleeve 213 can drive the fixed base 231 to rotate through the second spline shaft 233. At the same time, the fixed base 231 will drive all the structures connected to it to rotate. The setting of the ball can evenly share the pressure of the fixed base 231 to prevent the fixed base 231 from tilting. When the fixed base 231 rotates, the two second transmission gears 237 will rotate above the fixed plate 241, so that when one second transmission gear 237 is meshed with an arc-shaped rack 242, the other second transmission gear 237 will just mesh with the corresponding The arc-shaped rack 242 is disengaged, so that when the radar antenna body 236 rotates with the second spline shaft 233 as the axis, the radar antenna body 236 will also swing with the second rotating shaft 235 as the axis, thereby increasing the signal receiving range of the radar antenna body 236, and accurately positioning the directional drilling mobile trolley 101. At this time, the first servo motor 105 is started, and the first servo motor 105 drives the threaded rod 106 to rotate. The threaded rod 106 drives the mounting plate 107 and the slider 108 to move up and down along the track of the slide rail 104 through the threaded sleeve. Before the mounting plate 107 moves downward, the drilling machine 109 is started to drill.
