Description

Technical Field

[0001] The invention relates to the technical field of inspection robots, and in particular to an image correction device for a hydraulic corridor inspection robot. Background Art

[0002] In order to ensure the firmness and stability of the dam, it is usually necessary to open a hydraulic corridor inside the dam. The purpose is to be able to observe the internal situation of the dam at any time for emergency treatment. However, there are many pipes and equipment distributed inside the hydraulic corridor, which need to be inspected regularly. Inspection robots are now often used to conduct regular inspections of various facilities inside the hydraulic corridor.

[0003] However, in the prior art, due to the different heights of various pipes and instruments in the hydraulic corridor, the inspection robot needs to continuously move up and down by means of the support arm for adjustment during the inspection process. In this process, the camera lens may be skewed due to the bumps caused by the swing of the support arm. The skew of the lens may easily cause the subsequent shots of the interior of the hydraulic corridor that need to be inspected to be skewed and incomplete, making it impossible to shoot the specified positions of some pipes or instruments during inspection, thereby hindering the inspection of the instruments or pipes. Summary of the invention

[0004] The purpose of the present invention is to solve the problem in the prior art that due to the different heights of various pipes and instruments in the hydraulic corridor, the inspection robot needs to continuously move up and down for adjustment during the inspection process by means of a support arm. In this process, the shooting lens may be skewed due to the bumps caused by the swing of the support arm. The skew of the lens may easily cause the subsequent shooting of the interior of the hydraulic corridor to be skewed and incomplete, making it impossible to shoot some pipes or instruments at designated positions during inspection, thereby hindering the inspection of the instruments or pipes. A hydraulic corridor inspection robot image correction device is proposed.

[0005] In order to achieve the above-mentioned objectives, the present invention adopts the following technical solutions: a hydraulic corridor inspection robot image correction device, comprising an inspection robot body, the inspection robot body comprising an installation box, fixed plates are fixedly installed on both sides of the installation box, positioning plates are fixedly installed on the top and bottom ends of the two fixed plates, two pressure plates are slidably installed inside the four positioning plates, two dampers are fixedly installed on one side of the two pressure plates, two correction heads are fixedly installed on the other ends of the four dampers, and reset springs are sleeved on the outer surfaces of the four dampers.

[0006] Preferably, circular through holes are provided on one side of the two fixed plates near the upper and lower edges, and adjustment columns are movably provided inside the four circular through holes. Two adjustment plates are fixedly installed on one end of the four adjustment columns, and adjustment bolts are rotatably installed inside the two adjustment plates. Threaded through holes are provided on one side of the two fixed plates near the middle position, and the other ends of the two adjustment bolts are threadedly installed in the two threaded through holes, and the other ends of the four adjustment columns are fixedly installed on one side of the two pressure plates.

[0007] Preferably, limiting rods are fixedly connected to one side of the two pressure plates and near the upper and lower edges, limiting grooves are provided at the top and bottom ends of the two correction heads, and the clamping heads of the four limiting rods are slidably installed inside the four limiting grooves respectively.

[0008] Preferably, an elastic rubber sheet is fixedly mounted on the other side of the two correction heads, a lens is arranged on the other side of the two elastic rubber sheets, and the other side of the two elastic rubber sheets is in contact with the outer surface of the lens.

[0009] Preferably, the inner diameter of the circular through hole is the same as the diameter of the adjusting column, and the outer surface of the adjusting bolt is meshed with the inner surface of the threaded through hole.

[0010] Preferably, the inner size of the positioning plate is the same as the width of the pressure plate, and the size of the clamping head of the limiting rod is the same as the inner size of the limiting groove.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] 1. In the present invention, pressure is applied to the reset spring during the sliding process of the pressure plate, and a reaction force is generated during the contraction of the reset spring, thereby pushing the two correction heads to move.

[0019] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0021] Embodiment 1

[0022] like Figure 1-4As shown, the present invention provides an image correction device for a hydraulic corridor inspection robot, including an inspection robot body 1, the inspection robot body 1 includes an installation box 2, fixed plates 3 are fixedly installed on both sides of the installation box 2, and positioning plates 4 are fixedly installed on the top and bottom ends of the two fixing plates 3, and two pressure plates 5 are slidably installed inside the four positioning plates 4, and two dampers 11 are fixedly installed on one side of the two pressure plates 5, and two correction heads 12 are fixedly installed on the other ends of the four dampers 11, and the outer surfaces of the four dampers 11 are sleeved with reset springs 17, and the two pressure plates 5 are fixedly installed on the other ends of the four dampers 11. A limiting rod 13 is fixedly connected to one side of the pressure plate 5 near the upper and lower edges. A limiting groove 14 is provided at the top and bottom ends of the two correcting heads 12. The clamping heads of the four limiting rods 13 are respectively slidably installed in the four limiting grooves 14. An elastic rubber sheet 15 is fixedly installed on the other side of the two correcting heads 12. A lens 16 is provided on the other side of the two elastic rubber sheets 15. The other sides of the two elastic rubber sheets 15 are in contact with the outer surface of the lens 16. The internal size of the positioning plate 4 is the same as the width of the pressure plate 5, and the clamping head size of the limiting rod 13 is the same as the internal size of the limiting groove 14.

[0023] The specific settings and functions of this embodiment are described in detail below. When the lens 16 needs to be calibrated, the two pressure plates 5 are pushed to slide between the four positioning plates 4 by rotating the two adjusting bolts 8. During the sliding of the pressure plate 5, pressure is applied to the return spring 17. During the contraction of the return spring 17, a reaction force is generated, thereby pushing the two correction heads 12 to move. Finally, the lens 16 is centered and calibrated under the squeezing action of the two correction heads 12. By setting the limit groove 14 and the limit rod 13, the correction head 12 can be limited, and the correction head 12 can be effectively prevented from being skewed and falling off. By setting the positioning plate 4, the pressure plate 5 can be moved in a directional manner to ensure the stability of the pressure plate 5 during the movement process. By setting the return spring 17, a stable reaction force can be applied to the correction head 12, thereby making the correction head 12 more firm. By setting the elastic rubber sheet 15, the lens 16 can be protected.

[0024] Embodiment 2

[0025] like Figure 1 and Figure 2As shown, circular through holes 9 are opened on one side of the two fixed plates 3 and near the upper and lower edges, and adjusting columns 6 are movably arranged inside the four circular through holes 9. Two adjusting plates 7 are fixedly installed on one end of the four adjusting columns 6, and adjusting bolts 8 are rotatably installed inside the two adjusting plates 7. Threaded through holes 10 are opened on one side of the two fixed plates 3 and near the middle position, and the other ends of the two adjusting bolts 8 are threadedly installed with the inside of the two threaded through holes 10 respectively. The other ends of the four adjusting columns 6 are fixedly installed on one side of the two pressure plates 5 respectively. The inner diameter of the circular through hole 9 is the same as the diameter of the adjusting column 6, and the outer surface of the adjusting bolt 8 is meshed with the inner surface of the threaded through hole 10.

[0026] The effect achieved by the entire embodiment is that, by rotating the two adjusting bolts 8, the adjusting bolts 8 enter into the threaded through hole 10 during the rotation process, and can push the adjusting plate 7 to move, and in the process of the movement of the adjusting plate 7, the adjusting column 6 is pushed to move inside the circular through hole 9. As the adjusting column 6 moves, the correction head 12 is pushed to clamp and correct the lens 16. By setting the adjusting bolts 8, the correction head 12 can be fixed, and the distance between the two correction heads 12 can be adjusted. By setting two adjusting columns 6, the pressure plate 5 can be made more stable during the movement.

[0027] The usage and working principle of the device are as follows: the staff rotates the two adjusting bolts 8 so that the adjusting bolts 8 enter into the threaded through hole 10 during the rotation process, and are able to push the adjusting plate 7 to move, and push the adjusting column 6 to move inside the circular through hole 9 during the movement of the adjusting plate 7. As the adjusting column 6 moves, pressure is applied to the reset spring 17 during the sliding of the pressure plate 5, and a reaction force is generated during the contraction of the reset spring 17, thereby pushing the two correction heads 12 to move, and finally the lens 16 is centered and corrected under the squeezing action of the two correction heads 12.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
