Description

TECHNICAL FIELD

[0001] The present application belongs to the field of fixed installation of equipment, and particularly relates to a fixing device of electronic equipment. BACKGROUND

[0002] Closed industrial furnaces such as blast furnaces have high-temperature, high-pressure, high-dust and other in-furnace environments, so it is difficult to observe through the observation window with the naked eye. For this reason, various detection devices have been proposed to obtain in-furnace information, such as infrared cameras, microwave scanners, etc. Some of these detection devices are arranged outside the furnace shell and transmit and / or receive detection signals through the observation window, but this can hinder detection because the observation window is prone to dust accumulation. Therefore, it is envisaged to arrange detection elements such as cameras and other sensors inside the furnace.

[0003] CN1156149C discloses an insertion-type furnace camera, which includes a camera gun, a tubular cooler, a sealing valve and a sealing sleeve. The front end of the camera gun is provided with a camera and a temperature measuring element. The camera gun passes through the sealing sleeve and the sealing valve until the front end of the tubular cooler, so that the camera and the temperature measuring element at the front end of the camera gun are located inside the blast furnace. Since the camera gun is sealed by the sealing sleeve and the sealing valve, the sealing valve can be closed when the camera gun is pulled out to the space between the sealing valve and the sealing sleeve during the production process of the blast furnace, and then the camera gun is pulled out of the sealing sleeve to carry out maintenance and maintenance. It should be noted that there are no moving parts in the camera gun.

[0004] Chinese patent application CN118655696A proposes a laser scanning device, which can include a laser gun and a sleeve into which the laser gun is inserted. The laser scanning device can be installed to an industrial furnace such as a blast furnace, with the head end of the laser scanning device extending into the furnace and the tail end located outside the furnace, and the laser emitted from the head end can be scanned in the furnace to obtain in-furnace information. The laser gun is used to transmit the laser generated by a laser generator outside the furnace into the furnace. The sleeve can protect the laser gun to adapt to the harsh environment in the furnace, and the sleeve can also provide other auxiliary and support functions. In an embodiment of the laser gun, the laser transmission line extends in the elongated gun barrel of the laser gun and is used to transmit the laser, which is collimated by a collimating mirror and reflected by a reflecting mirror into the furnace. The reflecting mirror frame with the reflecting mirror is driven to rotate by a motor-driven assembly to perform scanning operations within a predetermined scanning angle range. The present application relates to changes and / or improvements to the laser scanning device in the Chinese patent application, and therefore the entire content of the patent application is incorporated into the present specification by reference.

[0024] The technical solutions of the application will be described in detail below with reference to the accompanying drawings.

[0025] As Figure 1 shown, the furnace observation device can include an observation barrel 1 and an outer sleeve 2 into which the observation barrel 1 is inserted, and both of them can be elongated. For the sake of simplicity of description, the left end of each figure will be referred to as the tail end, and the right end will be referred to as the head end. The outer sleeve 2 can have an inner cavity extending along its length inside it for receiving the inserted observation barrel 1 therein. The observation barrel 1 can be inserted into the outer sleeve 2 from the tail end of the outer sleeve 2 and until the head end of the observation barrel 1 reaches the head end of the outer sleeve 2, thereby forming the furnace observation device in an assembled state as Figure 1 shown. The tail end of the observation barrel 1 can be exposed outside the outer sleeve 2 so that the observation barrel 1 can be easily inserted into and pulled out of the outer sleeve 2 while holding the tail end. Although the part of the observation barrel 1 inserted into the outer sleeve 2 is generally not visible from the outside, this part is schematically drawn in order to more clearly see the arrangement of the observation barrel 1 inside the outer sleeve 2. Figure 1

[0026] Figure 1 ​The shown furnace observation device can be installed on an industrial furnace such as a blast furnace, with its head end extending into the furnace and its tail end outside the furnace. In operation, the head of the observation gun 1 has observation equipment such as a camera or a laser scanner for scanning the interior of the blast furnace to obtain information about the interior of the furnace, while the outer sleeve 2 can protect the observation gun 1 and provide other auxiliary and support functions.

[0027] The head end of the observation gun 1 has a camera or a laser emitter, both of which need to be powered by a cable or transmit signals to the outside through a cable. When the camera or laser emitter is mounted on a round tubular gun barrel, it is usually fixed by screw connection. Since the cable carried by the camera or laser emitter needs to be pulled out from the gun barrel, the cable is easily broken during rotation when fixed by screw connection.

[0028] To solve the above problems, the present application uses multiple protection devices to cooperate with the camera or laser emitter, without rotation, the camera or laser emitter can be fixed and installed on the gun barrel. The technical solution of the present application can not only be used in the installation of the camera or laser emitter, but also can be applied to the fixed installation of various electronic devices with cables.

[0029] As shown in Figure 2 and Figure 3 , the electronic device fixing device provided by the present application is provided. The electronic device 101 is a device that needs to be fixed and installed, which can be a camera or a laser emitter, etc.

[0030] The electronic device fixing device can include a plug 102. The plug 102 is approximately cuboid in shape, the head end of which can be detachably connected with the electronic device 101, and the tail end of which can be detachably connected with the cable 103. The cable 103 can power the electronic device 101 through the plug 102, or transmit the optical or electrical signals generated by the electronic device 101. In other embodiments, the plug 102 can also be other shapes, as long as one side is a plane.

[0031] The electronic device 101 and the plug 102 can be placed in the outer protection cylinder 104. As shown in Figure 4As shown, the outer protective tube 104 can be a cylindrical structure. The tail end of the outer protective tube 104 can form a cylindrical structure with a slightly smaller diameter, and the top of the tail end can have an external thread, and the side of the external thread near the middle has two penetrating first positioning holes 1042. The two first positioning holes 1042 can be located at both ends of the diameter of the cross section of the outer protective tube 104. The inner wall of the outer protective tube 104 near the middle position can have two inwardly protruding platforms 1041. The surfaces of the two platforms 1041 are parallel to each other. A ring-shaped limit platform 1043 can extend inward from the platform 1041 near the tail end. The distance from the limit platform 1043 to the head end of the outer protective tube 104 is greater than the sum of the lengths of the electronic device 101 and the plug 102. When the electronic device 101 and the plug 102 are placed from the head end of the outer protective tube 103 into the outer protective tube 104, the two side surfaces of the plug 102 fit into the two platforms 1041, so that the electronic device 101 and the plug 102 cannot rotate in the outer protective tube 104, and the tail end of the plug 102 is blocked by the limit platform 1043 and cannot continue to penetrate the outer protective tube 104. In other embodiments, the number of first positioning holes 1042 can be one or more. The number of platforms 1041 can be one or more. The limit platform 1043 may not be annular, and it only needs to extend one or more protrusions inward from the inner wall of the outer protective tube 104 to prevent the plug 102 from moving.

[0032] When the electronic device 101 is a camera, the side surface of the plug 102 fits against the platform 1041 , so that the electronic device 101 and the plug 102 cannot rotate in the outer protective tube 104 , thereby ensuring the stability of the camera image.

[0033] A cylindrical gun barrel 106 can be inserted into the outer protective tube from the rear end of the outer protective tube 104. Figure 5 As shown, the tip of the gun barrel 106 may have two second positioning holes 1061 extending therethrough. The second positioning holes 1061 may be internally threaded. After the gun barrel 106 is inserted into the outer protective tube 104, the second positioning holes 1061 at the tip of the gun barrel 106 align with the first positioning holes 1042 on the outer protective tube 104. Set screws 107 can be screwed into the first and second positioning holes 1042, 1061, to securely connect the gun barrel 106 to the outer protective tube 104. In other embodiments, the number of second positioning holes 1061 in the gun barrel 106 may be one, two, or more.

[0034] When the barrel 106 is fixedly connected with the outer protective cylinder 104, the positioning screw 107 can be covered by the gland 105 to prevent loosening of the positioning screw 107. The gland 105 can have a cylindrical structure, and the head end thereof can have internal threads to be threadedly connected with external threads of the tail end of the outer protective cylinder 104. In other embodiments, the tail end of the outer protective cylinder 104 can be connected with the gland 105 in a snap-fit manner or the like, as long as the gland 105 can cover the positioning screw 107 after being connected with the outer protective cylinder 104. The diameter of the tail end of the outer protective cylinder 104 can be the same as that of the middle part of the outer protective cylinder 104.

[0035] After the electronic device 101 and the plug 102 are placed in the outer protective cylinder 104, the electronic device 101 and the plug 102 cannot move toward the tail end of the outer protective cylinder 104 due to the blocking effect of the limiting table 1043. In order to prevent the electronic device 101 and the plug 102 from moving toward the head end of the outer protective cylinder 104, the compression ring 108 can be sleeved on the electronic device 101. The head end of the compression ring 108 can have external threads, and correspondingly, the head end of the outer protective cylinder 104 can have internal threads. After the external threads of the head end of the compression ring 108 are threadedly connected with the internal threads of the head end of the outer protective cylinder 104, the tail end of the compression ring 108 abuts against the head end of the plug 102, so that the electronic device 101 and the plug 102 cannot move toward the head end of the outer protective cylinder 104. As shown in Figure 6 The compression ring 108 has a cylindrical structure, and a plurality of operation holes 1081 can be arranged on the end face of the head end of the compression ring 108. In the furnace, dust is relatively large, and the electronic device 101 needs to be blown to prevent dust accumulation from affecting the function of the electronic device 101. The operation holes 1081 can be used as air ducts to facilitate blowing of the electronic device 101. Meanwhile, when the compression ring 108 is threadedly connected with the outer protective cylinder 104, a tool can be inserted into the operation hole 1081 to facilitate rotation of the compression ring 108, so that the compression ring 108 is quickly threadedly connected with the outer protective cylinder 104. In other embodiments, the operation holes 1081 on the end face of the head end of the compression ring 108 can be one or more.

[0036] In order to prevent the head end of the electronic device 101 from being damaged by the external environment, the fixing device can further include an outer protective cap 109. The head end of the outer protective cap 109 can be arranged to be similar to the shape of the head end of the electronic device 101. The head end of the outer protective cap 109 can have an opening, which can be used as an air duct to facilitate blowing of the electronic device 101. When the electronic device 101 is a camera or a laser instrument, the opening can also be used as a shooting channel of the camera or a laser emission channel. The tail end of the outer protective cap 109 can have external threads to be threadedly connected with internal threads of the head end of the outer protective cylinder 104. As shown in Figure 7As shown, in order to facilitate the threaded connection of the outer protective cap 109 and the outer protective barrel 104, the head end of the outer protective cap 109 can be formed with a plurality of protrusions 1091, which serve as force points when rotating the outer protective cap 109. In other embodiments, the head end of the outer protective cap 109 can be formed with one or more protrusions 1091. The tail end of the outer protective cap 109 and the head end of the outer protective barrel 104 can also be connected in other detachable ways, such as snap connection, etc.

[0037] The installation process of the fixing device of the electronic device can include:

[0040] Third, the plug 102 and the electronic device 101 are inserted into the outer protective barrel 104 from the head end of the outer protective barrel 104, so that the tail end of the plug 102 abuts against the limiting table 1043 of the outer protective barrel 104, and the flat surface on the side of the plug 102 abuts against the platform 1041 of the outer protective barrel 104.

[0041] Fourth, the compression ring 108 is inserted into the outer protective barrel 104 in a tail-in direction, and is sleeved on the electronic device 101, and the outer thread at the head end of the compression ring 108 is threadedly connected with the inner thread at the head end of the outer protective barrel 104, so that the tail end of the compression ring 108 abuts against the head end of the plug 102.

[0042] Fifth, the outer thread at the tail end of the outer protective cap 109 is threadedly connected with the inner thread at the head end of the outer protective barrel 104.
