It is composed of a camera, a serial communication module, an image acquisition module, an image processing module, etc. It has the functions of carbon bowl image acquisition, carbon bowl center and chute position calculation, and communication with the electrical system. For example, before cleaning the carbon bowl, the carbon block is first positioned by a visual identifier, the carbon bowl is photographed, the situation of each carbon bowl is previewed, and the position of the center of each carbon bowl is given. The data is transmitted to the Kongzihao system through communication, which plays an important role in the precise positioning of the scraping tool.

[0003] The existing visual identifier is generally hoisted above the cleaning line. During the cleaning process, compressed air will blow the carbon particles and dust that have fallen off the surface of the carbon block and the carbon bowl out of the carbon bowl, and small particles of flying dust will float above the carbon blocks. Although a negative pressure dust suction device is installed on the cleaning line, some flying dust will still float up and block the recognition window of the visual identifier, and adhere to the recognition window to block the recognition window. After working for a long time, the visual identifier will not be able to accurately observe and identify the position information of the carbon bowl, which greatly affects the precise positioning of the scraper's working position. Moreover, since the visual identifier is hoisted on the top of the factory building, it is difficult to maintain and clean it, and it is easy to cause safety accidents during maintenance.

It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model, that is, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings can be arranged and designed in various different configurations.

[0035] The protective box involved in the utility model is mainly used in a carbon block cleaning line to provide external protection for a visual identifier, in order to prevent flying dust from floating onto the identification window of the visual identifier and blocking the identification window, and from attaching to internal components and causing short circuits.

[0036] The specific implementation of the protective box is, for example, Figures 1 to 4 As shown, it includes a box body 1. In this embodiment, the box body 1 is a mounting carrier for all other components, and the whole is a rectangular box-type structure. Of course, in other embodiments, the specific structure is not limited, and technicians in this field can design it arbitrarily according to the actual scene, such as a circle, square, polygon, etc.

[0037] The top of the box 1 has a hanging structure. According to the installation position of the visual identifier, the box 1 is hung just above the carbon block cleaning line of the factory. Correspondingly, the hanging structure includes a connection hole arranged on the top of the box 1, and a hanger 2 is connected to the connection hole. The hanger 2 is used to be fixedly connected to the crossbeam above the cleaning line. Of course, in other embodiments, the hanging structure can also be in the form of a hanging beam, which is directly fixed on the top wall of the factory building, or it can be fixed on one side of the cleaning line by other brackets and cantilevered just above the cleaning line.

[0038] The bottom opening 11 of the box body 1 is mainly for facilitating the visual identifier to avoid blocking the identification window of the visual identifier during operation.

[0039] The interior of the box body 1 has a mounting portion for mounting a visual identifier, and the visual identifier is fixed to the inner top wall of the box body 1 by bolt connection, with the visual window facing directly downward, so as to facilitate the collection of carbon block surface information.

[0040] In order to realize the protection function of the visual identifier, a switch door is blocked at the opening 11 of the box body 1, and a driving mechanism for driving the switch door to open and close is arranged on the box body 1. The box body 1 is also connected to a blowing nozzle 7 inserted into the interior of the box body 1. The blowing nozzle 7 is used to connect with an external device when the switch door is opened to introduce high-pressure gas into the box body 1.

[0041] As a preferred embodiment, the switch door is a sliding door 3, and the driving mechanism is a horizontal driving mechanism connected to one side of the sliding door 3 to open and close the switch door. Specifically, guide grooves 12 are provided on the side walls on both sides of the width direction of the lower end of the box body 1, and the two side edges of the sliding door 3 are guided and assembled in the guide grooves 12, so that the sliding door 3 can be guided and moved in the horizontal direction. The horizontal driving mechanism can cooperate with the sliding door 3 to drive the sliding door 3 to move horizontally to block the opening 11 and open the opening 11.

[0042] Of course, in other embodiments, the switch door can also be set as a double door or a flip door, or a folding door or other alternative forms in the prior art, as long as the opening 11 of the box body 1 can be opened and closed. The corresponding driving mechanism is also designed as a flip driving mechanism or a folding driving mechanism.

[0043] As a preferred embodiment, in order to meet the compactness of the structure and facilitate control of the moving stroke of the lock pin sliding door 3, there are two sliding doors 3 arranged along the length direction of the box body 1. The two sliding doors 3 are relatively close to each other to block the opening 11, and are away from each other to open the opening 11.

[0044] Of course, in other embodiments, the sliding door 3 may also be designed to be two arranged along the width direction, or a single sliding door 3 may be used for opening and closing control.

[0045] As a preferred embodiment, in order to facilitate the driving of the two sliding doors 3 and ensure the compact design of the structure, the side walls on both sides of the width direction of the box body 1 are both guided and slidably equipped with mounting frames 4, and the two mounting frames 4 correspond to the two sliding doors 3 one by one, and the driving mechanism is connected to the mounting frames 4. In other embodiments, longer mounting frames 4 can also be directly arranged on both sides of the length direction of the box body 1 to directly drive the outer ends of the sliding doors 3 to move.

[0046] As a preferred embodiment, in order to ensure the stability of the rapid synchronous opening and closing of the sliding door 3, the driving mechanism includes guide rails 5 arranged on both sides of the width direction of the box body 1, the guide rails 5 extend along the length direction of the box body 1, the mounting frame 4 is guided and assembled on the guide rails 5, and the mounting frame 4 is connected to the driving cylinder 6. Of course, in other embodiments, the driving mechanism can also be replaced by other methods such as a ball screw mechanism, a cam push rod mechanism, a gear rack mechanism, etc., without specific limitation.

[0047] In order to achieve external protection for the driving machine, protective shells 13 are provided on both sides of the box body 1 in the width direction, and the driving mechanism is arranged in the protective shell 13. Of course, in other embodiments, the driving mechanism can also be arranged inside the box body 1 without interfering with the visual identifier.

[0048] As a preferred embodiment, in order to satisfy the symmetry of the moment of the sliding door 3 when the sliding door 3 is driven and avoid problems such as yaw, the mounting frame 4 has an overhanging portion extending to the bottom of the corresponding sliding door 3 and fixedly connected to the lower plate surface of the corresponding sliding door 3. The overhanging portion is connected to the center position of the door panel of the sliding door 3.

[0049] Of course, the mounting frame 4 includes a vertical plate 41 and a horizontal plate 42 connected to the vertical plate 41 . A guide seat 43 is arranged on the vertical plate 41 . The guide seat 43 is used to connect with the driving cylinder 6 . The horizontal plate 42 is cantilevered laterally to form the above-mentioned cantilevered portion.

[0050] In order to ensure that the air pressure inside the box 1 is sufficient after the sliding door 3 is opened, there are multiple blowing nozzles 7, which are distributed on both sides of the length direction of the box 1 and the top of the box 1. The blowing nozzles on both sides of the length direction of the box have several branch pipes, which are arranged in the width direction of the box at intervals near the opening position of the box. Through the structural design of the branch pipe arrangement, an air curtain can be formed at the opening.

[0051] During actual operation, when the scraper is cleaning the carbon blocks, the driving mechanism drives the sliding door 3 to close to prevent flying dust from entering the interior of the protective box; when the visual identifier is needed to work, the driving mechanism opens the sliding door 3 to expose the visual identifier, and at the same time the air blowing nozzle 7 works to introduce gas into the box body 1 to ensure that during the process of opening and closing the door, the air pressure in the box body 1 is higher than the external air pressure, thereby preventing external dust from entering the interior of the box body 1 and adhering to the identification window of the visual identifier.

[0052] The embodiment of the visual positioning device involved in the utility model includes a protection box and a visual identifier fixed in the protection box. The structure of the protection box is consistent with the structure of the above-mentioned embodiment of the protection box and will not be described in detail.
