Detailed Description

It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

The embodiment relates to a desuperheater pipeline crack detection device which is used for detecting a desuperheater pipeline and can be particularly used for detecting whether cracks are generated in an inner sleeve arranged in the desuperheater pipeline. In the detection form, the device enters the pipeline, walking and image acquisition can be performed under the control of an external remote control signal, and therefore the detection of whether the inner sleeve has the crack or not is realized by observing the acquired image.

Based on the above overall design concept, an exemplary structure of the detection device of the present embodiment is shown in fig. 1, and the detection device includes a chassis 1, a traveling mechanism with a magnetic adsorption type track 3 disposed on two opposite sides of the chassis 1, a control box 4 rotatably disposed on the chassis 1, and a driving mechanism disposed in the chassis 1 and capable of driving the traveling mechanism to travel and the control box 4 to rotate respectively.

Meanwhile, the desuperheater pipeline crack detection device of the embodiment further comprises a controller arranged in the control box 4, an image acquisition mechanism arranged on the control box 4 in a manner of moving transversely and longitudinally through a sliding rail mechanism, and a wireless signal transmission mechanism 12 arranged on the control box 4 and connected with the controller.

Wherein, above-mentioned actuating mechanism, slide rail mechanism and image acquisition mechanism also all are connected with the controller. It should be noted that the magnetic adsorption type track 3 of this embodiment is specifically a lateral portion of the chassis 1 provided with the rolling wheels 2, and the magnetic adsorption type track 3 adopts the existing structural design, and specifically, the magnetic adsorption type track 3 of this embodiment can refer to the relevant track structure in the chinese utility model patent (publication No. CN208698920U), and other structural parts matched with the track part are modified correspondingly.

In this embodiment, in addition to the magnetic adsorption type caterpillar 3, the rotation arrangement of the control box 4 on the chassis 1, and the driving mechanism driving the rolling wheels 2 and the control box 4 to rotate, it can be referred to the relevant parts of the prior electrically driven excavator or other similar mechanical products (especially the widely sold electrically driven simulated excavator toy).

In addition, it should be noted that the controller in this embodiment may be implemented by a single chip or other existing programmable circuit board module fixed inside the control box 4, and the wireless signal transmission mechanism 12 may also be implemented by an existing module product that performs wireless signal transmission through bluetooth, 4G, WIFI or even an emerging 5G network system. Through this wireless signal transmission mechanism 12, can realize the image signal's that image acquisition mechanism gathered to the real-time output of outside terminal station to can look over the inside sight of pipeline in real time in outside terminal station department.

In addition, for the external remote controller to send a control command to the controller in the detection device to control the motion of the detection device, such as walking, etc., the existing commonly used wireless remote control signal transmission mode can be directly adopted between the external remote controller and the controller, thereby also making the wireless signal transmission mechanism 12 mainly execute the image real-time transmission work. Therefore, the control of the walking of the detection device can not have any mutual influence with the terminal displaying the real-time image, so that when the detection is carried out, one detection person can operate the device, and other detection persons can be concentrated on watching the image.

As a possible implementation form, the slide rail mechanism of the present embodiment may be in transmission connection with the driving mechanism, so as to provide the driving force by the driving mechanism, so as to realize the lateral and/or longitudinal movement of the image capturing mechanism. At this time, the structure of the slide rail mechanism of the present embodiment specifically includes a longitudinal slide rail 7 fixedly disposed on the control box 4, a lateral slide rail 8 slidably disposed on the longitudinal slide rail 7 along the longitudinal slide rail 7, and a transmission mechanism 9 connected to the driving mechanism.

For the longitudinal slide rails 7, two longitudinal slide rails 7 may be disposed side by side and spaced apart from each other on the control box 4, and the transverse slide rail 8 may be only one and is slidably inserted into the two longitudinal slide rails 7 through two ends thereof. Meanwhile, the transmission mechanism 9 may adopt a conventional transmission structure such as a rack and pinion or a nut and screw, for example, so that the rotational power of the driving mechanism may be converted into a linear driving force for linearly sliding the cross slide rail 8 and the image capturing mechanism.

In this embodiment, a plurality of different motors are used as the driving source of the driving mechanism for simplifying the structure and facilitating the design, so as to control the traveling of the entire body detecting device, the rotation of the control box 4, the sliding of the image capturing mechanism, and the like. Of course, instead of using a plurality of motors, it is also possible to use only one motor or another suitable number of motors, with reference to the existing related product structure.

However, in addition to making the slide rail mechanism driven by the driving mechanism, the present embodiment directly provides a driving mechanism such as a linear motor in the slide rail mechanism to realize the linear motion of the cross slide rail 8 and the image capturing mechanism by the correspondingly arranged linear motors, which is also possible. Moreover, in order to ensure the stability and smoothness of the sliding of the horizontal sliding rail 8 along the vertical sliding rail 7 and the sliding of the image acquisition mechanism along the horizontal sliding rail 8, the present embodiment may also make the cross section of the horizontal sliding rail and the vertical sliding rail be dovetail-shaped or trapezoidal, for example, so as to obtain a better guiding and restraining effect.

As a possible implementation structure, the image capturing mechanism of this embodiment specifically includes a collector base 5 disposed on a horizontal sliding rail 8 through a sliding support, and a camera 6 disposed on the collector base 5. Wherein, above-mentioned camera 6 adopts 360 panorama fisheye cameras to for the image acquisition effect that improves camera 6, also be provided with light filling lamp 11 on collector base 5.

The sliding arrangement of the sliding support on the horizontal sliding rail 8 in this embodiment is only required by referring to the sliding arrangement of the horizontal sliding rail 8 on the vertical sliding rail 7, and in this embodiment, a circuit module such as an image processor may be generally disposed in the collector base 5, so as to be able to transmit the collected image to the wireless signal transmission mechanism 12, and transmit the collected image to an external terminal through the wireless signal transmission mechanism 12.

In order to further improve the image capturing effect of the camera 6 and also facilitate the walking control of the device in the pipeline, the searchlight 10 is also arranged on the side part of the control box 4 in the embodiment, and the searchlight 10 generally adopts the existing LED bulb.

When the detection device is used, the device is placed at the position of a pipeline opening, then the camera 6, the light supplement lamp 11 and the searchlight 10 are started, then the remote controller is used for controlling the movement of the travelling mechanism, so that the whole device travels in the inner sleeve in the pipeline, and 360-degree panoramic scanning and shooting are carried out on the inner wall of the inner sleeve synchronously with the travelling. The image shot by the camera 6 is transmitted to an external terminal through a wireless signal transmission mechanism 12, the terminal can be a notebook or other special terminal equipment generally, and the transmitted image signal can be played on a terminal screen in real time, so that whether cracks are generated on the inner sleeve or not can be detected by watching a real-time video image.
