Description

Technical Field

[0001] The utility model relates to the technical field of survey devices, in particular to a cable channel survey device for electric power engineering design. Background Art

[0002] In addition to cylindrical cable channels, there are also square cable channels. In order to ensure the flatness of the inner wall of the square cable channel and improve the stability of the channel, the cable channel needs to be regularly maintained and inspected. Manual inspection not only has large errors, but also has low efficiency.

[0003] To this end, the utility model patent with application number CN202220737888.7 discloses a cable channel survey device in the field of power survey, which solves the defect that traditional survey devices rely on the operator's naked eye judgment, and once the judgment is wrong, it will lead to increased survey errors. However, in actual applications, when the rack moves inside the channel, it is difficult to ensure the constant distance between the rack and the inner wall of the channel. When the distance between the rack and the inner wall of the channel changes, the pressure value detected by the pressure sensor and the distance detected by the mid-range distance sensor will be distorted, reducing the accuracy of the survey results; and the device is not convenient for recording uneven parts of the channel, which has certain disadvantages.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0018] like Figures 1 to 3 As shown, a cable channel survey device for power engineering design includes a base plate 1, a walking wheel 2 is installed at the bottom of the base plate 1, a fixed box 3 is fixedly connected to the top, a push handle 4 is installed at the rear end of the fixed box 3, a battery, a PLC controller and a wireless communication module are installed inside the fixed box 3, three fixed rods 5 are fixedly connected to one side of the fixed box 3, rollers 6 are installed on the fixed rods 5, and the three fixed rods 5 are installed on the side of the fixed box 3 at equal intervals.

[0019] Through the design of the fixing rod 5 and the roller 6, when the roller 6 abuts against the channel wall, the distance between the bottom plate 1 and the channel wall is constant, thereby improving the accuracy of detection.

[0020] A mounting plate 7 is fixedly connected to the top of the fixing box 3 . Two detection components are installed on the mounting plate 7 at one side where the fixing rod 5 is located. A mounting frame 8 is provided between the two detection components. A camera 9 is installed on the mounting frame 8 .

[0021] By cooperating with the camera 9, the detection component can detect the flatness of the channel wall and take pictures of the uneven positions, which is convenient for the staff to analyze the reasons for the unevenness of the channel wall and carry out subsequent maintenance and treatment on the uneven parts.

[0022] The detection component includes a protective box 10, a rear end of the protective box 10 is fixedly connected to an adjustment plate 11, a sleeve 12 is provided on the outside of the adjustment plate 11, a fixing bolt 20 is threadedly connected to the top of the sleeve 12, the adjustment plate 11 is fixed to the inside of the sleeve 12 by the fixing bolt 20, the rear end of the sleeve 12 is fixedly connected to an ear plate 13, the ear plate 13 is mounted on the mounting plate 7 by screws, a slider 14 is provided inside the protective box 10, both ends of the slider 14 are connected with a limit rod 15, a spring 16 is sleeved on the outside of the limit rod 15, both ends of the limit rod 15 are fixedly connected to the inner wall of the protective box 10, the spring 16 is located between the slider 14 and the inner rear wall of the protective box 10, the front end of the slider 14 is fixedly connected to a connecting rod 17 that runs through the front end surface of the protective box 10, a detection wheel 18 is installed on the connecting rod 17, a distance sensor 19 is installed on the inner rear wall of the protective box 10, and a limit block 21 is fixedly connected to the inner bottom surface between the two limit rods 15.

[0023] By adjusting the length of the adjusting plate 11 exposed from the sleeve 12 and fixing it with the fixing bolts 20, the position of the detection wheel 18 can be adjusted, so that when the roller 6 abuts against the channel wall, the detection wheel 18 squeezes the slider 14 through the connecting rod 17. At this time, the spring 16 is compressed, and the distance sensor 19 monitors the position of the slider 14 in real time. When the wall surface is uneven, the degree of squeezing of the slider 14 by the detection wheel 18 is different, and the value monitored by the distance sensor 19 changes. The camera 9 takes a picture of the uneven area to facilitate analysis and processing by the staff.

[0024] In specific use, the push handle 4 is used to push the device to move, and the roller 6 and the detection wheel are in contact with the channel wall. At the same time, the detection wheel 18 squeezes the slider 14 through the connecting rod 17, and the spring 16 is compressed. When the value detected by the distance sensor 19 changes, it indicates that the wall surface is uneven. The camera 9 takes pictures of the unevenness to facilitate the staff to analyze and process. The roller 6 always contacts the channel wall during the movement, so that the distance between the bottom plate 1 and the channel wall is constant, thereby improving the accuracy of the detection.
