[0001] This utility model relates to the field of industrial equipment technology, and in particular to an automatic opening and closing device for a detection port. Background Technology

[0002] Industrial smelting furnaces are typically equipped with detection ports on the furnace body for checking the liquid level or melt temperature. These ports are opened and closed via a cover plate. Currently, the cover plate is mostly opened and closed manually. Due to the high temperature at the detection port location, high-temperature flue gas with positive pressure is sometimes emitted, creating a harsh working environment. Furthermore, the frequent manual opening and closing of the cover plate poses significant safety hazards. Utility Model Content

[0003] In view of the above-mentioned defects in the prior art, this utility model provides an automatic opening and closing cover device for the detection port to solve the technical problems of harsh working environment and potential safety hazards.

[0004] To achieve the above and other related objectives, this utility model provides an automatic opening and closing cover device for a detection port, comprising: a cover plate hinged to a support base and disposed adjacent to the detection port; a power mechanism for driving the cover plate to open or close the detection port; and a control module electrically connected to the power mechanism for issuing control commands.

[0008] In one embodiment of this utility model, the power mechanism includes: a stop block, which is fixedly installed on the output shaft of the speed-regulating motor; a limit switch, which forms a limit engagement with the stop block and outputs a switch signal to the control module when the speed-regulating motor runs to the fully open and closed state of the cover plate; and a limit switch bracket, which is used to fix the limit switch, and the limit switch bracket is fixedly installed on the speed-regulating motor bracket or support base.

[0009] In one embodiment of the present invention, the outer peripheral wall of the detection port is cylindrical, and the length direction of the rotation axis is perpendicular to the axial direction of the detection port.

[0010] In one embodiment of this utility model, the control module is a programmable logic controller.

[0011] In one embodiment of the present invention, a protective cover is included. The protective cover is generally hood-shaped and is placed on the power mechanism to protect the power mechanism.

[0012] The beneficial effects of this utility model are as follows: The automatic opening and closing cover device for the detection port proposed in this utility model, by setting up a power mechanism and a control module, allows the operator to remotely operate the control module and send the control command for opening or closing the cover to the power mechanism.

[0017] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other. In addition to the specific methods, equipment, and materials used in the embodiments, based on the knowledge of the prior art and the description of this utility model by those skilled in the art, any prior art method, equipment, and materials similar to or equivalent to those described in the embodiments of this utility model can be used to implement this utility model.

[0018] It should be understood that the terminology used in the embodiments of this utility model is for describing specific implementations and not for limiting the scope of protection of this utility model. Unless otherwise defined, all technical and scientific terms used in this utility model have the same meaning as commonly understood by those skilled in the art.

[0019] The structures, proportions, and sizes depicted in the accompanying drawings are solely for illustrative purposes and to aid those skilled in the art. They are not intended to limit the implementation of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed herein. Furthermore, the drawings only show components relevant to this invention and are not drawn according to the actual number, shape, and size of components in practice. In actual implementation, the form, quantity, and proportion of each component can be arbitrarily changed, and the component layout may be more complex.

[0020] Please see Figure 1 and Figure 2 This utility model provides an automatic opening and closing cover device for a detection port, comprising: a cover plate 100, hinged to a support base A and located near the detection port B. The support base A described here can be the furnace shell with the detection port B, or any stable structure near the detection port B; a power mechanism for driving the cover plate 100 to open or close the detection port B; and a control module electrically connected to the power mechanism for issuing control commands. By setting up the power mechanism and the control module, the operator can remotely operate the control module to send control commands to open or close the cover plate 100 to the power mechanism, which automatically drives the cover plate 100 to open or close. This eliminates the need for on-site operation, avoids safety hazards, and prevents operators from working in harsh environments.

[0021] In a specific embodiment of this utility model, it includes: a seated bearing 300, fixedly installed on the outer peripheral wall of the support base A body or the detection port B; a rotating shaft 400, with a cover plate 100 hinged to the seated bearing 300 via the rotating shaft 400; and a power mechanism driving the cover plate 100 to rotate around the rotating shaft 400 to open or close the detection port B. The cover plate 100 can be opened and closed in various ways, such as translation or rotation. In this embodiment, rotation is used, hence the rotating shaft 400. The seated bearing 300 mainly facilitates the installation of the rotating shaft 400. The seated bearing 300 can be installed on the support base A body, or as... Figure 1 It is installed on the outer peripheral wall of the detection port B as shown.

[0022] In a specific embodiment of this utility model, the power mechanism includes: a speed-regulating motor 201, used to provide power for opening or closing the cover 100; and a speed-regulating motor bracket 202, fixed on the support base A for mounting the speed-regulating motor 201. Many mechanisms can provide power, such as cylinders and motors. In this embodiment, a speed-regulating motor 201 is selected, which can be reliably used in this scenario.

[0023] In a specific embodiment of this utility model, the power mechanism includes: a first sprocket 203 mounted on the output shaft of a speed-regulating motor 201; a second sprocket 204 mounted on a rotating shaft 400; and a chain 205 mounted between the first sprocket 203 and the second sprocket 204 for driving the second sprocket 204 to rotate when the first sprocket 203 rotates. Power transmission is achieved through the cooperation of the sprockets and the chain 205, making it very durable.

[0024] In the above embodiments, a motor with higher control precision could be used, but this would significantly increase the cost. We chose a common variable-speed motor 201, and to ensure the durability of the device, we used a chain 205 and a sprocket for power transmission. This approach controls costs and extends service life, but the opening and closing of the cover 100 is not as precise. In a specific embodiment of this utility model, the power mechanism includes: a stop block 206, fixedly mounted on the output shaft of the variable-speed motor 201; a limit switch 207, which forms a limiting engagement with the stop block 206 and outputs a switch signal to the control module when the variable-speed motor 201 runs to the fully open and closed state of the cover 100; and a limit switch bracket 208, used to fix the limit switch 207, which is fixedly mounted on the variable-speed motor bracket 202 or support A. Here, by setting a limit switch 207, a switch signal is output to the control module when the cover 100 is fully closed or open. The control module can then shut down the speed-regulating motor 201 when the cover 100 is fully closed or open, thus ensuring the reliability of the opening and closing of the cover 100.

[0025] In a specific embodiment of this utility model, the outer peripheral wall of the detection port B is cylindrical, and the length direction of the rotating shaft 400 is perpendicular to the axial direction of the detection port B. This makes the space occupied by the cover plate 100 when opening and closing smaller, and the detection port B can be fully exposed after opening, making it convenient to view.

[0026] In one specific embodiment of this utility model, the control module is a programmable logic controller (hereinafter referred to as PLC). Industrial smelting furnaces are generally controlled by PLCs, so in this embodiment, no additional control module is added, and the control function of the control module is directly implemented by the PLC, thus saving costs.

[0027] In one specific embodiment of this utility model, a protective cover 500 is included. The protective cover 500 is generally hood-shaped and is installed on the power mechanism to protect it. The environment near the smelting furnace is relatively harsh, so the protective cover 500 can effectively protect these components and extend their service life.

[0028] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
