Description

Technical Field

[0001] The invention relates to the technical field of in-pipe radar ranging robots, in particular to a self-propelled in-pipe radar ranging robot. Background Art

[0002] The in-pipe radar ranging robot automatically walks inside the pipeline, and then uses radar technology to measure the distance of the physical quantity sensed and measured by the radar in the pipeline from the target. Therefore, the in-pipe radar ranging robot can perform inspection and measurement of the pipeline very well, reducing the workload of the staff and solving the problem of distance measurement in the pipeline.

[0003] The patent name disclosed in the prior art with application number "CN202011345074.0" is "A geological radar robot in a pipe and a geological detection system in a pipe", which discloses that the geological radar is installed on the geological radar installation assembly; the geological radar installation assembly is connected to the carrying platform, and the two ends of the carrying platform are connected with a first driving mechanism and a second driving mechanism; the first driving mechanism and the second driving mechanism move axially along the inner wall of the pipe, and the geological radar detects underground cavities in the underground pipe, which can solve the problem of not being able to take into account both the detection depth and the detection resolution at the same time. Problem: When a low-frequency antenna is selected, cavities of greater depth can be detected, and cavities of smaller size can be distinguished; when a medium- and high-frequency antenna is selected, cavities of smaller size can be distinguished, and cavities of greater depth can be detected while walking in the pipeline. Moving the geological radar into the pipeline can make the geological radar closer to the diseased body (loose soil / empty soil / cavity around the pipeline), and then a high-frequency antenna can be selected for detection, which can not only improve the resolution of the detection results, but also detect and distinguish diseased bodies of smaller size, and then find the diseased body in the "germination" state, which has the effect of early prevention;

[0004] In the prior art, the patent name disclosed by the application number "CN202110704223.6" is "A Distance Measuring Device, Laser Radar and Mobile Robot", which discloses that the laser emitting unit is used to emit pulsed laser to the target object to be measured. The laser emitting unit can be constructed as a laser diode, which can emit laser pulses for ranging. The pulsed laser emitted by the laser emitting unit can be a high-frequency pulsed laser, for example, a pulsed laser of more than 1kHz. For example, the laser emitting unit of the laser diode can be mounted on the circuit board by welding, or integrated on the circuit board. The optical axis X3 of the laser emitting unit can be arranged to be perpendicular to the circuit board. A control device for controlling the laser emitting unit to emit laser pulses can be installed on the circuit board, and this control device can be integrated in the computing unit, so that the computing unit becomes a master control device. It can be understood that in other embodiments, other devices capable of emitting lasers can also be used as laser emitting units.

[0005] The first receiving unit is used to receive the pulsed laser reflected from the target object and generate a corresponding first signal; the first signal is used to calculate and determine the distance according to the principle of triangulation, that is, the first signal is used to be transmitted to the calculation unit, so that the calculation unit can calculate and determine the distance based on the first signal and according to the principle of triangulation. The first receiving unit can be mounted on the circuit board by welding, or be integrated on the circuit board. The optical axis X2 of the first receiving unit can be set to be perpendicular to the circuit board. When sensing the laser pulse reflected back by the target object, the first receiving unit can generate a corresponding photoelectric signal and transmit it to the calculation unit through the line on the circuit board. The calculation unit can analyze and calculate the photoelectric signal according to the principle of triangulation to obtain the distance between the target object and the ranging device;

[0006] 1. When the above-mentioned in-pipe radar ranging robot is not in use, its main ranging components and components such as cameras are exposed to the outside world. Therefore, they may be hit by the outside world during transportation or movement, which may cause certain damage to these components, thereby affecting the radar ranging sensor's ranging work inside the pipe through radio waves;

[0007] 2. When the above-mentioned in-pipe radar ranging robot enters the pipeline for ranging, it will drag the wires because it moves automatically, causing the longer wires to contact the inner wall of the bottom of the pipeline, thereby generating greater friction, which can easily cause the surface of the wires to be damaged, thereby affecting the use of the entire in-pipe radar ranging robot;

[0008] So we proposed a self-propelled in-tube radar ranging robot to solve the above problems. Summary of the invention

[0036] Compared with the prior art, the beneficial effects of the present invention are as follows: the self-propelled in-pipe radar ranging robot can well protect the radar ranging sensor mechanism and the camera mechanism, so that the radar ranging sensor mechanism can well perform ranging work in the pipe through radio waves, and the three rotating rods drive the crawling self-propelled wheels to rotate synchronously, so that the crawling self-propelled wheels can drive the in-pipe radar ranging robot to walk automatically, which can reduce the contact area between the power line and the inner wall of the bottom surface of the pipeline, thereby reducing the friction force of the in-pipe radar ranging robot dragging the power line when it walks automatically in the pipe. The specific contents are as follows:

[0037] (1) The mounting frame is automatically controlled to slide into the protective outer frame through the first sliding control component, so that the mounting frame can drive the radar ranging sensor mechanism and the camera mechanism to enter the protective outer frame for protection when not in use, thereby preventing the entire in-pipe radar ranging robot from causing collision damage to the radar ranging sensor mechanism and the camera mechanism when the in-pipe radar ranging robot is transported and moved when not in use. Therefore, the radar ranging sensor mechanism and the camera mechanism can be well protected, which facilitates the radar ranging sensor mechanism to perform ranging work inside the pipe through radio waves, and facilitates the camera mechanism to monitor the situation inside the pipe;

[0038] Furthermore, when the support plate rises, the first connecting rope in the first sliding control assembly can provide a power source for the rotation of the first control rod, without using an additional power source, thus saving energy and production costs;

[0039] The motor inside the outer shell drives one of the rotating rods to rotate, so that one of the rotating rods cooperates with the sprocket assembly to drive the other two rotating rods to rotate, thereby making the three rotating rods drive the crawling self-propelled wheels to rotate synchronously, so that the crawling self-propelled wheels drive the radar ranging robot in the tube to automatically walk;

[0040] The stirring plate is rotated back and forth at a certain angle with the center of the circle of the crossbar as the center, so that the stirring plate can be used in conjunction with the clamping mechanism to reciprocate and throw the power cord upward, so that one end of the power cord moves up and down in a wave-like manner. This operation is repeated, so that when the in-pipe radar ranging robot automatically walks in the pipe, the contact area between the power cord and the inner wall of the bottom surface of the pipeline can be reduced, thereby reducing the friction force of the in-pipe radar ranging robot dragging the power cord when automatically walking in the pipe, and then the power cord can be protected, so that the entire in-pipe radar ranging robot can be used for ranging well;

[0041] (2) When the support plate rises, the second push rod in the second sliding control assembly automatically pushes the anti-collision beam outward, so that the anti-collision beam slides out of the outer shell for use. When the entire in-tube radar ranging robot is not in use, the anti-collision beam can automatically slide into the outer shell for storage, thereby reducing the overall length and occupied area of ​​the in-tube radar ranging robot, making it easier to move and carry the in-tube radar ranging robot in the future;

[0042] The second connecting rope in the second sliding control assembly can provide a power source for the rotation of the second control rod, without the need for an additional power source, thus saving energy;

[0043] (3) Through the intermittent meshing connection between the sector gear and the second gear, the crossbar can be driven to reciprocate at a certain angle, so that the crossbar drives the support plate to reciprocate at a certain angle. At the same time, when the rotating rod rotates, the meshing connection between the first gear and the transmission gear can drive the control rod to rotate, so that when the in-pipe radar ranging robot is automatically walking, the stirring plate can synchronously reciprocate and rotate;

[0044] When the mounting bracket enters the protective outer frame, the rack automatically drives the gear ring to rotate, so that the gear ring drives the outer protective cover to rotate on the outside of the radar ranging sensor mechanism, so that the first through hole and the second through hole are staggered, and then the outer protective cover blocks the second through hole, so that when the radar ranging sensor mechanism is not in use, foreign matter is prevented from entering the radar ranging sensor mechanism through the second through hole, thereby further protecting the radar ranging sensor.

[0062] The first sliding control assembly includes a first control rod 17 installed through the left side of the protective outer frame 5, a first vertically arranged push rod 171 is installed on the outer side of the first control rod 17, a mounting frame 6 is arranged on the right side of the first push rod 171, and the mounting frame 6 forms a sliding structure with the inside of the protective outer frame 5 through the first push rod 171. The first sliding control assembly also includes a first connecting rope 16 wound around the outer side of the front end of the first control rod 17, the lower end of the first connecting rope 16 is connected to the upper surface of the outer shell 1, and the height of the first connecting rope 16 not wound around the outer side of the first control rod 17 is greater than the shortest distance from the first control rod 17 to the upper surface of the outer shell 1; a first torsion spring 172 is sleeved on the outer side of the front end of the first control rod 17, and the rear end of the first torsion spring 172 is connected to the front side of the protective outer frame 5.

[0063] A second slider 91 is installed on both the front and rear side surfaces on the left side of the anti-collision beam 9. The second slider 91 is slidably connected to the groove opened in the right side of the outer shell 1. A second connecting spring 92 is connected to the groove opened in the right side of the outer shell 1. One end of the second connecting spring 92 is connected to the second slider 91. The second sliding control assembly includes a second control rod 18 installed through the upper surface of the right side of the outer shell 1. A second push rod 182 is fixed through the lower outer side of the second control rod 18. The anti-collision beam 9 is arranged on the right side of the second push rod 182. The anti-collision beam 9 forms a sliding structure with the outer shell 1 through the second push rod 182; the second sliding control assembly also includes a second connecting rope 23 wound around and connected to the upper outer side of the second control rod 18. The upper end of the second connecting rope 23 is connected to the bottom surface of the support plate 3 after being guided by a guide wheel. A second torsion spring 181 is nested and connected to the lower outer side of the second control rod 18;

[0064] When the entire self-propelled in-pipe radar ranging robot is not in use, the mounting frame 6 drives the radar ranging sensor mechanism 8 and the camera mechanism 15 to enter the protective outer frame 5, so that the outer sides of the radar ranging sensor mechanism 8 and the camera mechanism 15 can be protected by the protective outer frame 5 to prevent the radar ranging sensor mechanism 8 and the camera mechanism 15 from being damaged by external impact, so that the radar ranging sensor mechanism 8 can be used well;

[0065] Then the entire in-pipe radar ranging robot is moved into the working area. After reaching the working area, the right end of the in-pipe radar ranging robot is inserted into the pipeline. At this time, the crawling self-propelled wheels 12 on both sides of the in-pipe radar ranging robot contact the inner wall of the pipeline, so that the in-pipe radar ranging robot remains stable in the pipeline. Then the electric telescopic rod 4 is started. At this time, the output end of the electric telescopic rod 4 drives the support plate 3 to move upward. At this time, the support plate 3 drives the protective outer frame 5 to move upward. At this time, the support frame 2 connected to the bottom of the support plate 3 rotates, so that the sliding column 201 under the support frame 2 slides on the outside of the limit rod 202. Since the limit rod 202 is installed in the groove in the outer shell 1, the support frame 2 stably assists the support plate 3 to be supported upward, ensuring the stability of the support plate 3 rising. Then, after the support plate 3 rises to a certain height, the work of the electric telescopic rod 4 is stopped;

[0066] As attached Figure 1 and attached Figure 7-Figure 8 As shown, and attached Figure 1 and attached Figure 4-Figure 5As shown, at the same time, when the support plate 3 drives the protective outer frame 5 to move upward, the support plate 3 will pull the second connecting rope 23 with a reserved length, and the protective outer frame 5 will pull the first connecting rope 16 with a reserved length. When the reserved length of the second connecting rope 23 is straightened, the support plate 3 continues to pull the second connecting rope 23, so that the second connecting rope 23 drives the second control rod 18 to rotate. At this time, the second control rod 18 drives the second torsion spring 181 to store force, and at the same time, the second control rod 18 drives the second push rod 182 to rotate, so that the second push rod 182 pushes the anti-collision beam 9 to move outward. At this time, the second slider 91 outside the side of the anti-collision beam 9 slides in the groove in the outer shell 1, and the second connecting spring 92 is squeezed and stored, so that the anti-collision beam 9 can be well slid out for use;

[0067] At the same time, after the protective outer frame 5 straightens a certain length reserved for the first connecting rope 16, the protective outer frame 5 continues to pull the first connecting rope 16, and the first connecting rope 16 drives the first control rod 17 to rotate, and then the first torsion spring 172 accumulates force, and the first control rod 17 drives the first push rod 171 to rotate together, and the first push rod 171 pushes the mounting frame 6 to the right, and the first sliders 61 on the upper and lower sides of the mounting frame 6 slide in the grooves in the protective outer frame 5 to squeeze and accumulate force on the first connecting spring 62, so that the mounting frame 6 drives the fill light 7, the radar ranging sensor mechanism 8 and the camera mechanism 15 to slide out of the protective outer frame 5 well, which is convenient for the use of the fill light 7, the radar ranging sensor mechanism 8 and the camera mechanism 15;

[0068] Then, the motor in the outer shell 1 is started, and the motor drives one of the rotating rods 121 to rotate. At this time, one of the rotating rods 121 drives the other two rotating rods 121 to rotate through the sprocket assembly 122, so that the three rotating rods 121 simultaneously drive the three sets of crawling self-propelled wheels 12 to rotate, so that the crawling self-propelled wheels 12 drive the radar ranging robot in the pipe to automatically move in the pipe. At this time, the anti-collision beam 9 detects the front side to prevent objects from hitting the radar ranging sensor mechanism 8 on the front side, and then the fill light 7 fills the light around the camera mechanism 15, so that the camera mechanism 15 can well record and shoot the surrounding area to monitor the situation in the pipe. At the same time, the transmitter, transmitting antenna, receiver and receiving antenna and other components in the radar ranging sensor mechanism 8 cooperate with each other and cooperate with the second through hole 84 to perform good ranging work in the pipe through radio waves (since this part is a prior art, it will not be introduced in detail here);

[0069] Embodiment 2: Based on Embodiment 1, the radar ranging robot in the pipe can reduce the friction between the power line 11 and the inner wall of the pipe. Figure 1-Figure 3 , and attached Figure 9-12, three groups of rotating rods 121 are rotatably connected inside the bottom surface of the outer shell 1, and creeping self-propelled wheels 12 are installed at the front and rear ends of the rotating rods 121. The outer sides of the three groups of rotating rods 121 form a synchronous rotation structure through a sprocket assembly 122; the outer side key of the leftmost rotating rod 121 is connected to the first gear 123, and the left side of the first gear 123 is meshed and connected with a transmission gear 192, and a regulating rod 19 is fixed inside the transmission gear 192, and the two ends of the regulating rod 19 are rotatably connected to the inside of the outer shell 1; the outer side key of the rear end of the regulating rod 19 is connected to a fan-shaped gear 191, and the left side key of the fan-shaped gear 191 is connected to a second gear 22, and a cross bar 20 is fixed inside the second gear 22, and the cross bar 20 is installed on the left side of the outer shell 1, and a provoking plate 13 is fixed on the outer side of the cross bar 20, and a third torsion spring 21 is connected to the outer side of the front end of the cross bar 20. A bidirectional screw rod 141 is installed in a groove inside the left end of the stirring plate 13, and the outer side of the bidirectional screw rod 141 is symmetrically threadedly connected with a clamping mechanism 14. One side of the two clamping mechanisms 14 is concave-convexly matched with the power line 11. The stirring plate 13 forms a reciprocating rotating structure with the outer shell 1 through the cross bar 20;

[0070] Manually rotate the bidirectional screw rod 141, then the bidirectional screw rod 141 drives the two clamping mechanisms 14 to move inward at the same time, and the cooperation of the two clamping mechanisms 14 clamps the power cord 11, and then the leftmost rotating rod 121 drives the first gear 123 on the outside to rotate together when rotating, and the first gear 123 drives the transmission gear 192 meshing on the left to rotate, and the transmission gear 192 rotates to drive the internal regulating rod 19 to rotate, and the regulating rod 19 drives the outer fan gear 191 to rotate, and when the fan gear 191 rotates to mesh with the second gear 22, the fan gear 191 drives the second gear 22 to rotate, and the second gear 22 drives the cross bar 20 to rotate clockwise at a certain angle, and then the third torsion spring 21 accumulates force, and the cross bar 20 drives The movable stirring plate 13 rotates clockwise at a certain angle with the center of the circle of the cross bar 20 as the center, so that the left end of the stirring plate 13 drives the power cord 11 to be thrown upward through the clamping mechanism 14. When the fan gear 191 rotates to be out of mesh with the second gear 22, the stored force of the third torsion spring 21 automatically drives the second gear 22 and the cross bar 20 to rotate counterclockwise at a certain angle to reset. When the stirring plate 13 repeatedly throws the power cord 11 upward, the power cord 11 moves upward in a wave shape and then falls downward in the later stage. This repetition can reduce the contact area between the power cord 11 and the inner wall of the pipeline, so that the radar ranging robot in the pipeline can automatically walk inside the pipeline and reduce the friction between the power cord 11 and the inner wall of the pipeline when dragging the power cord 11, thereby protecting the power cord 11 well.

[0071] Embodiment 3: The radar ranging robot in the pipe in this embodiment can further protect the radar ranging sensor mechanism 8, as shown in the attached Figure 4-Figure 6 As shown, the surface of the radar ranging sensor mechanism 8 is provided with two second through holes 84; the outer side of the radar ranging sensor mechanism 8 is rotatably connected with an outer protective sleeve 81, and a gear ring 82 is installed on the outer side of the outer protective sleeve 81. The surface of the outer protective sleeve 81 is symmetrically provided with two first through holes 83, and the first through holes 83 are correspondingly arranged with the second through holes 84. A rack 51 is installed on the inner wall of the rear side of the protective outer frame 5, and the front side of the rack 51 is meshedly connected with the gear ring 82. The outer protective sleeve 81 forms a rotating structure with the radar ranging sensor mechanism 8 through the gear ring 82, and a control mechanism 10 is installed on the upper left surface of the outer shell 1;

[0072] When the mounting bracket 6 moves to the right, when the ring gear 82 moves to mesh with the rack 51, the fixed rack 51 will drive the ring gear 82 to rotate, so that the ring gear 82 drives the outer protective sleeve 81 to rotate. After the outer protective sleeve 81 rotates to a certain angle, the ring gear 82 moves to separate from the rack 51. Then, at this time, the first through hole 83 opened on the surface of the outer protective sleeve 81 coincides with the second through hole 84 opened on the surface of the radar ranging sensor mechanism 8, so that the radar ranging sensor mechanism 8 can perform ranging work. Conversely, when the mounting bracket 6 moves to the left, as shown above, At this time, the rack 51 drives the gear ring 82 and the outer protective cover 81 to rotate in the opposite direction. At this time, the first through hole 83 opened on the surface of the outer protective cover 81 and the second through hole 84 opened on the surface of the radar ranging sensor mechanism 8 are arranged alternately, so that the outer protective cover 81 can block the second through hole 84 opened on the surface of the radar ranging sensor mechanism 8, so as to prevent external dust and impurities from entering the radar ranging sensor mechanism 8 through the second through hole 84 when the radar ranging sensor mechanism 8 is not in use, thereby further protecting the radar ranging sensor mechanism 8, thereby completing a series of tasks.
