Description

Technical Field

[0001] The present invention belongs to the technical field of monitoring, and particularly relates to a composite probe based on laser heterodyne interference technology. Background Art

[0002] Laser heterodyne interference technology has now been widely applied to probes for speed measurement, length measurement, angle measurement, and vibration measurement. Each section of the road is equipped with a probe for speed measurement to monitor the passing vehicles. When fixing the probe, it is necessary to adjust the direction of the monitoring section. Currently, the probes are generally fixed at a high position by screws, which is inconvenient for adjustment during fixation. Therefore, we propose a composite probe based on laser heterodyne interference technology. Summary of the Invention

[0003] The purpose of the present invention is to provide a composite probe based on laser heterodyne interference technology. By arranging a friction block inside a sliding groove, the round rod can be adjusted inside the sliding groove through the friction block. The friction block will increase stability by elastically squeezing the inner bottom of the sliding groove through an elastic piece, thus solving the existing problems.

[0004] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0005] The present invention is a composite probe based on laser heterodyne interference technology, including a probe. A round rod is arranged at the bottom of the probe. The probe can be fixed on the surface of the round rod, and the angle of the probe can be adjusted through the round rod. The surfaces of the round rod and the round frame are both arc-shaped, reducing the wind resistance and preventing the probe from being blown crooked in strong winds, which affects the working efficiency. A connecting plate is arranged at the bottom of the round rod, and a round frame is arranged at the bottom of the connecting plate. A concave hole is opened at the bottom of the round frame;

[0006] A water-blocking mechanism is arranged on the outer surface of the probe, a clamping mechanism is arranged on the outer surface of the round rod, the number of the clamping mechanisms is two, an adjusting mechanism is arranged at one end of the clamping mechanism far away from the round rod, and a fixing mechanism is arranged inside the round frame;

[0007] The water-blocking mechanism includes a connecting rod, a circular ring frame, and an inclined plate. The connecting rod is fixedly connected to the outer surface of the probe, the number of the connecting rods is four, one end of the connecting rod far away from the probe is fixedly connected to the circular ring frame, and the inclined plate is fixedly connected to the outer surface of the circular ring frame.

[0008] Further, the adjusting mechanism includes an adjusting frame, a fixed disk, a sliding groove, a friction block, and a spring piece. The fixed disk is arranged inside the adjusting frame. A sliding groove is formed at one end of the fixed disk close to the adjusting frame. The friction block is arranged inside the sliding groove. The adjusting frame is fixedly connected to the bottom of the connecting plate. The connecting plate limits and fixes the round rod through the round frame. The spring piece is fixedly connected to the side part of the adjusting frame. The friction block presses and fixes the bottom inner wall of the sliding groove by using the elasticity of the spring piece;

[0009] There are four friction blocks. One end of the friction block close to the adjusting frame is fixedly connected to the spring piece. The other end of the friction block away from the sliding groove is fixedly connected to the spring piece. The other end of the spring piece away from the friction block is fixedly connected to the inner wall of the adjusting frame.

[0010] Further, the positioning mechanism includes a round hole, a clamping rod, a clamping block, and a clamping groove. A round hole is formed in the inner wall of the round rod. A clamping groove is formed in the inner wall of the round hole. A clamping groove is formed on the surface of the round rod. The clamping rod can be fixed inside the clamping groove through the clamping block, which facilitates the disassembly of the measuring head driven by the round rod. The clamping rod is arranged inside the round hole. The outer surface of the clamping rod is fixedly connected to the clamping block;

[0011] There are four clamping grooves and four clamping blocks. The clamping blocks are in contact with the inner wall of the clamping groove.

[0012] Further, the end of the clamping rod away from the round rod is fixedly connected to the outer surface of the fixed disk. The clamping rod is arranged inside the round hole.

[0013] Further, the fixing mechanism includes a semi-circular frame, a bent plate, a chain plate, and an elastic spring. The top of the semi-circular frame is fixedly connected to the top inner wall of the round frame. When the round frame is pushed against the outer surface of the object to be fixed, the bent plate will contract towards the inside of the round frame by extrusion. When the bent plate contracts, it will pull the elastic spring to separate the chain plates, so that the chain plates can contact and fix the surface of the object. The end of the semi-circular frame is movably connected to the bent plate through a pin shaft. The chain plate is arranged inside the semi-circular frame;

[0014] There are two chain plates. Elastic springs are fixedly connected to the ends of the two chain plates away from each other.

[0015] Further, the end of the elastic spring away from the chain plate is fixedly connected to the inner wall of the semi-circular frame. The bent plate extends to the outer end of the round frame through the concave hole.

[0016] Further, the top of the connecting plate is fixedly connected to the bottom of the adjusting frame. The round rod is arranged above the connecting plate.

[0017] Further, the outer surface of the friction block is in contact with the inner wall of the sliding groove. The bottom outer surface of the friction block is in contact with the bottom inner wall of the sliding groove.

[0018] The present invention has the following beneficial effects:

[0019] A circular ring frame is arranged on the outer surface of the probe of the present invention. When rainwater drops onto the surface of the circular ring frame, it will slide down through the slope of the inclined plate to protect the surface of the probe. The circular ring frame is separated from the surface of the probe through a connecting rod, so that the inclined plate can be inclined at the top of the probe to reduce the contact between oblique rain and the probe.

[0020] The round rod of the present invention is fixedly connected to the outer surface of the fixed disk through a clamping rod. The sliding groove on the surface of the fixed disk is limited by a friction block. The number of friction blocks is four. By fixing the fixed disk in four directions inside the adjusting frame, after the round rod is adjusted through the fixed disk, the friction block uses the elastic force of the elastic sheet to clamp and fix the fixed disk.

[0021] The fixed disk of the present invention can be adjusted through the friction block. Twisting the round rod will drive the fixed disk to rotate on the surface of the friction block through the clamping rod. The sliding groove is opened at 360 degrees, and the fixed disk can be adjusted at various angles on the surface of the friction block.

[0022] The upper and lower ends of the chain plate of the present invention will deform under the pressure of the elastic spring. When the chain plate is deformed by extrusion, it will fit the surface to be fixed, and the chain plate will be fixed on the surface of the object through the extrusion of the elastic spring.

[0023] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The adjusting mechanism 5 includes an adjusting frame 50, a fixed disk 51, a sliding groove 52, a friction block 53 and a spring piece 54. A fixed disk 51 is arranged inside the adjusting frame 50. A sliding groove 52 is opened at one end of the fixed disk 51 close to the adjusting frame 50. A friction block 53 is arranged inside the sliding groove 52. In the present invention, the round rod 3 is fixedly connected with the outer surface of the fixed disk 51 through a clamping rod 41. The sliding groove 52 on the surface of the fixed disk 51 is limited by the friction block 53. The number of the friction blocks 53 is four.

[0041] One end of the clamping rod 41 far from the round rod 3 is fixedly connected with the outer surface of the fixed disk 51. The clamping rod 41 is arranged inside the round hole 40.

[0042] The fixing mechanism 6 includes a semi-circular frame 60, a bent plate 61, a chain plate 62 and an elastic spring 63. The top of the semi-circular frame 60 is fixedly connected to the top of the inner wall of the circular frame 8. One end of the semi-circular frame 60 is movably connected to the bent plate 61 through a pin shaft. There is a certain distance between the ends of the two bent plates 61 that are close to each other. When the bent plate 61 contacts the surface of the object, it contracts towards the inside of the semi-circular frame 60 by using the extrusion force. When the object enters and contacts the surface of the semi-circular frame 60 and the chain plate 62, the bent plate 61 expands towards the outer end of the bottom of the semi-circular frame 60 by using the extrusion of the elastic spring 63. When the bent plate 61 expands towards the outer end of the semi-circular frame 60, it contacts the bottom of the inner wall of the circular frame 8 to limit the bent plate 61. A chain plate 62 is arranged inside the semi-circular frame 60. In the present invention, the upper and lower ends of the chain plate 62 are deformed by the pressurization of the elastic spring 63. When the chain plate is deformed by extrusion, it fits the surface to be fixed. The chain plate 62 is fixed to the surface of the object by the extrusion of the elastic spring 63;

[0043] There are two chain plates 62. Elastic springs 63 are fixedly connected to the ends of the two chain plates 62 that are away from each other.

[0044] The end of the elastic spring 63 away from the chain plate 62 is fixedly connected to the inner wall of the semi-circular frame 60. The bent plate 61 extends to the outer end of the circular frame 8 through the concave hole 7. The chain plate 62 is composed of a plurality of chain plates 62 movably connected through pin shafts.

[0045] The top of the connecting plate 9 is fixedly connected to the bottom of the adjusting frame 50. The round rod 3 is arranged above the connecting plate 9.

[0046] The outer surface of the friction block 53 contacts the inner wall of the sliding groove 52, and the bottom outer surface of the friction block 53 contacts the bottom of the inner wall of the sliding groove 52.

[0047] A specific application of this embodiment is as follows: The circular frame 8 is pushed against the outer surface of the object to be fixed. When the object enters the interior of the circular frame 8, it will squeeze the bent plate 61. The bent plate 61 contracts towards the interior of the circular frame 8 by using the squeezing force of the object. There is a certain distance between the ends of the two bent plates 61 that are close to each other. When the bent plate 61 contacts the surface of the object, it contracts towards the interior of the semi-circular frame 60 by using the squeezing force. When the object enters and contacts the surfaces of the semi-circular frame 60 and the chain plate 62, the bent plate 61 expands towards the outer end of the bottom of the semi-circular frame 60 by using the extrusion of the elastic spring 63. When the bent plate 61 moves towards the interior of the semi-circular frame 60, two bent plates 61 are movably connected to the end of the semi-circular frame 60 through a pin shaft. When the object contacts the bent plate 61 at the bottom of one end of the semi-circular frame 60, the bent plate 61 contracts into the interior of the semi-circular frame 60 by using the squeezing force of the object. When the object enters the interior of the semi-circular frame 61, it slides towards the interior of the semi-circular frame 60 by using the curvature of the bent plate 61. The bent plate 61 at the contracted end will contact the inner wall of the chain plate 62 at the other end inside the semi-circular frame 60. The object is fixed by contacting the inner wall of the chain plate 62 by using the curvature of the surface of the bent plate 61. When the bent plate 61 contacts the surface of the object, it will contract towards the interior of the semi-circular frame 60 around the pin shaft by using the squeezing force. When the bent plate 61 contracts into the semi-circular frame 60, the ends and the top of the chain plate 62 are arranged in an arc shape. When the object enters the inner wall of the semi-circular frame 60 by using the bent plate 61, it will contact the end of the chain plate 62. The object will slide into the mutually close ends of the chain plate 62 through the curvature of the bent plate 61. The chain plates 62 are separated from each other by the extrusion of the object. When the chain plate 62 contacts the surface of the object, the upper and lower ends of the chain plate 62 will bend by using the elasticity of the elastic spring 63. The chain plate 62 bends by using the elastic force of the elastic spring 63 to contact the surface of the object. The object is fixed inside the semi-circular frame 60 by the clamping force of the chain plate 62 for limiting. When the bent plate 61 contracts, it will pull the elastic spring 63 to separate the chain plates 62, so that the chain plates 62 can contact the surface of the object. The chain plate 62 will deform by the extrusion of the elastic spring 63 and fit on the surface of the object for fixing. The block 42 and the rod 41 are pushed into the interior of the slot 43 and the round hole 40 to limit and fix the round rod 3. The rod 41 is fixedly connected to the outer surface of the fixed disk 51. The fixed disk 51 can be limited inside the adjusting frame 50 through the friction block 53. By twisting the round rod 3, the fixed disk 51 rotates on the surface of the friction block 53 to adjust the angle of the probe 1. The friction block 53 is stuck inside the sliding slot 52 by using the elasticity of the elastic piece 54 to fix the round rod 3.
