Description

Technical Field

[0001] The present invention relates to the technical field of industrial instruments, in particular to an industrial automation instrument protection device. Background Art

[0002] Industrial automation instruments are tools used to detect, display, record or control process parameters during industrial production. Detection of process production is a basic means of understanding and controlling process production. Only by accurately understanding the overall picture of the process at any time and controlling it can we ensure a smooth production process and produce qualified products with high productivity and low consumption.

[0003] Most industrial automation instruments are displayed through LCD screens, and on-site workers can accurately understand the current process data through the displayed readings. However, in some complex production scenarios, collisions between people or objects and liquid dripping onto the visible surface are inevitable. In the existing technology, most of the industrial automation instruments are protected by providing a protective shell on the outside. Conventional protection methods can only reduce the damage to the surface caused by the impact force, but cannot effectively weaken and absorb the impact energy, which can easily cause the internal parts to loosen and affect the monitoring accuracy. At the same time, most of the protective devices currently available on the market do not have the function of preventing liquid from falling onto the visible surface, resulting in the visible surface easily becoming blurred due to water stains after long-term use. Moreover, if used in scenarios where chemicals are present, the chemicals attached to the surface can easily cause corrosion to the visible surface, resulting in a reduction in the service life of the protective device. To this end, the present invention provides an industrial automation instrument protection device to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figure 1-6 The present invention provides a technical solution: a protective device for an industrial automation instrument, comprising an industrial instrument body 1, a plurality of fixed support rods 2 fixed to the bottom of the industrial instrument body 1, a fixed seat 3 fixed between the ends of the plurality of fixed support rods 2 away from the industrial instrument body 1, a fixed frame 4 fixed to the outside of the industrial instrument body 1, a placement tray 5 fixed to the bottom of the outside of the fixed frame 4, a movable frame 6 movably placed on the top of the placement tray 5, a protective mechanism 700 for protecting the industrial instrument body 1 installed on the inside of the movable frame 6, a connecting mechanism 800 for preventing dust and water from being installed on the top of the movable frame 6, and a wind curtain assembly 900 for blocking the connecting mechanism 800 from wind.

[0033] In the above-mentioned embodiment, through the coordinated use between the movable frame 6 and the protective mechanism 700, the movable frame 6 can be used as an upper and lower limit, and the internal industrial instrument body 1 can be protected by the movable frame 6. The compression energy absorption characteristics of the gas medium are utilized to absorb and weaken the impact energy, thereby reducing the energy transmission distance and size, thereby protecting the industrial instrument body 1 and the internal parts. Through the use of the wind curtain assembly 900, a wind curtain that can block liquid dripping can be formed on the visible surface by the blown air. At the same time, it can also play a dust-proof effect, so that the dust around the surface can be blown away, and it can also prevent water or chemicals from adhering to the visible surface for a long time, thereby avoiding the generation of water stains and the occurrence of corrosion problems. In summary, the advantages of being able to absorb and weaken the impact energy and preventing liquid from dripping and adhering to the visible surface are achieved, so that the visible surface can remain clear for a long time.

[0034] It should be noted that the top of the fixing base 3 is provided with a plurality of round holes for screws to pass through, so that the fixing base 3 can be connected to the device to be monitored or the pipeline through the cooperation of the round holes and the screws.

[0035] In this embodiment, the protection mechanism 700 is a structure for protecting the industrial instrument body 1 .

[0036] like Figure 1 and Figure 6 As shown, the protective mechanism 700 includes an installation component 7010 installed at the bottom of the movable frame 6 and used to play an upper and lower limiting role, a patch ring 702 affixed to the outside of the fixed frame 4, and air springs 703 fixedly installed between the inner side of the movable frame 6 and the outer side of the patch ring 702 and evenly distributed; the installation component 7010 includes two fixed rods 7011 fixed to the bottom of the movable frame 6, a limit block 7012 fixed to the outside of the fixed rod 7011, a positioning block 7013 movably sleeved on the outside of the limit block 7012, a nut 7014 abutting against the bottom of the positioning block 7013, two extension plates 7015 fixed to the outside of the fixed rod 7011, and a plurality of balls 7016 movably connected to the top of the extension plate 7015 and affixed to the bottom of the placement plate 5.

[0037] It should be noted that the air spring 703 is distributed in a circular shape on the outside of the patch ring 702, so that the air spring 703 can block and buffer the impact force from the outside. The air spring 703 is a spring filled with compressed air in a retractable closed container and uses the elasticity of air. Unlike conventional metal springs, the air spring 703 will not vibrate back and forth when under pressure, so it can be used in scenarios that require shock absorption protection.

[0038] In addition, two movable holes are provided at the bottom of the placement tray 5 for the two fixing rods 7011 to pass through and move, respectively, so that the fixing rods 7011 can move inside the movable holes, so that the movable frame 6 can be displaced laterally. A limiting groove for the corresponding limiting block 7012 to be inserted is provided on the side of the positioning block 7013 close to the placement tray 5. The limiting block 7012 is square, so that the limiting block 7012 can be inserted into the inner side of the corresponding limiting groove and can limit the positioning block 7013.

[0039] In addition, an external thread groove is provided at the bottom of the outer side of the fixing rod 7011 for the nut 7014 to be threadedly connected, so that the nut 7014 can be normally threadedly connected to the outer side of the fixing rod 7011 through the external thread groove, and can play a role in abutting and limiting the bottom of the positioning block 7013. An auxiliary corner block is fixedly connected between the bottom of the extension plate 7015 and the outer side of the positioning block 7013, and the auxiliary corner block can play a role in auxiliary support for the extension plate 7015.

[0040] It should also be noted that a rolling groove for the ball 7016 to be inserted into the top of the extension plate 7015 is provided, and two-thirds of the area of the outer side of the ball 7016 is located on the inner side of the corresponding rolling groove, so that the ball 7016 can rotate under the limiting action of the rolling groove, which can reduce the friction force, so that the extension plate 7015 can not only play the role of upper and lower limiting, but also allow the movable frame 6 to be displaced laterally, so that the air spring 703 can play a good protective role.

[0041] In this embodiment, the connecting mechanism 800 is a structure used for connection and convenient opening, and can also block dust from the top.

[0042] like Figure 1 、 Figure 4 and Figure 5 As shown, the connecting mechanism 800 includes a cover plate 801 hinged to the top of the movable frame 6 by a hinge, a connecting component 8020 fixed between the movable frame 6 and the outer side of the cover plate 801 and used to connect the movable frame 6 and the cover plate 801; the connecting component 8020 includes two connecting cylinders 8021 fixed to the right side of the cover plate 801, two mounting grooves 8022 opened on the inner side of the connecting cylinder 8021, an elastic member 8023 fixed on the inner side of the mounting groove 8022, and a connecting member 8023 fixed near the connecting member 8023. A triangular plug 8024 is provided on one side of the cylinder 8021; a guide rod 8025 is fixed to the triangular plug 8024 on the side facing the elastic member 8023; a limit plate 8026 is fixed to the end of the guide rod 8025 away from the corresponding triangular plug 8024; two support plates 8027 are fixed to the right side of the movable frame 6 and are positioned corresponding to the two connecting cylinders 8021; and a clamping member is slidably connected to the top of the support plate 8027 and can be clamped by the two corresponding triangular plugs 8024.

[0043] The clamping part includes a sliding rod 8028 passing through the top of the support plate 8027, a grip plate 8029 fixed to the bottom end of the sliding rod 8028, a limiting plate 8030 fixed to the outside of the sliding rod 8028, a first round table 8031 slidably connected to the outside of the sliding rod 8028, and a second round table 8032 fixed to the top of the sliding rod 8028 and located inside the corresponding connecting tube 8021.

[0044] It should be noted that a visual window located on the top of the industrial instrument body 1 is pierced and fixed on the top of the cover 801. The visual window is a transparent acrylic plate or transparent glass, so that outside staff can observe the readings of the industrial instrument body 1 through the visual window. The bottom of the connecting tube 8021 is open, so that the first cone 8031 and the second cone 8032 can normally enter the interior of the connecting tube 8021. The elastic part 8023 is a spring and can have an elastic recovery effect.

[0045] In addition, the side of the triangular plug 8024 close to the support plate 8027 is an inclined surface, which is symmetrically distributed with respect to the first circular platform 8031 and the second circular platform 8032. The diameter of the top of the first circular platform 8031 is larger than the diameter of the bottom of the second circular platform 8032, so that the first circular platform 8031 can push the triangular plug 8024 to move through the inclined surface of the triangular plug 8024. When the second circular platform 8032 is located inside the connecting tube 8021, the tops of the two triangular plugs 8024 can limit the bottom of the second circular platform 8032, so that the second circular platform 8032 cannot move downward. Since the diameter of the first circular platform 8031 is larger than the diameter of the second circular platform 8032, after the first circular platform 8031 passes over the triangular plug 8024, the triangular plug 8024 can move to the outside of the second circular platform 8032, thereby allowing the second circular platform 8032 to detach from the inside of the connecting tube 8021.

[0046] At the same time, the opposite ends of the two corresponding guide rods 8025 respectively penetrate the interior of the corresponding elastic member 8023 and the outside of the connecting tube 8021, and the limiting plate 8026 is located on the outside of the corresponding connecting tube 8021, so that the elastic member 8023 can be stably compressed under the action of the guide rod 8025, and the position of the guide rod 8025 and the position of the triangular plug 8024 can be limited under the action of the limiting plate 8026, so that the triangular plug 8024 can be smoothly pushed by the first round table 8031 and the second round table 8032.

[0047] In addition, the limiting plate 8030 is located between the corresponding support plate 8027 and the opposite side of the first truncated cone 8031, and the limiting plate 8030 can be fitted with the bottom of the corresponding first truncated cone 8031. A connecting hole for the sliding rod 8028 to slide is provided on the top of the first truncated cone 8031, so that the first truncated cone 8031 can slide on the outside of the sliding rod 8028, and under the action of the limiting plate 8030, it can support the first truncated cone 8031.

[0048] In this embodiment, the air curtain assembly 900 is a structure used to set an air curtain on the visible surface, thereby playing the role of blocking water and dust.

[0049] like Figure 1 、 Figure 2 and Figure 3 As shown, the air curtain assembly 900 includes an air outlet duct 901 fixed to the side of the cover 801 away from the industrial instrument body 1, an air inlet duct 902 fixed to the outside of the movable frame 6, a corrugated tube 903 fixed between the ends of the air outlet duct 901 and the air inlet duct 902, two first air ducts 904 fixed to the front side of the air outlet duct 901, an inclined tube 905 fixed to the end of the first air duct 904 away from the air outlet duct 901, a second air duct 906 fixed to the front side of the air outlet duct 901, and a parallel tube 907 fixed to the end of the second air duct 906 away from the air outlet duct 901.

[0050] It should be noted that the bellows 903 is on the same side as the hinge of the hinged movable frame 6 and the cover 801, so that when the cover 801 is opened, the bellows 903 can be driven to change position without affecting the air inlet pipe 902 and the air outlet pipe 901. A flange is fixed to the other end of the air inlet pipe 902, which can be connected to the air outlet end of the compressor through the flange, so that the compressed air can be transported through the air inlet pipe 902.

[0051] In addition, the two inclined tubes 905 are symmetrically distributed, and the parallel tube 907 is located between the opposite sides of the two inclined tubes 905. The parallel tubes 907 and the inclined tubes 905 are both provided with air outlet slots on the side away from the air outlet duct 901. Exhaust nozzles that are connected to the corresponding parallel tubes 907 or the inclined tubes 905 and are evenly distributed are fixedly installed on the inner side of the air outlet slots, so that the air inside the air outlet duct 901 can be ejected through the exhaust nozzles on the front of the parallel tubes 907 and the inclined tubes 905, so that the ejected air can form a wind curtain on the top of the cover plate 801 to block dripping liquid and dust.

[0052] The working principle of the above embodiment is:

[0053] (1) When protecting the instrument in operation, the movable frame 6 is placed on the outside of the industrial instrument body 1, and the patch ring 702 is fitted with the outside of the industrial instrument body 1. At the same time, the two fixing rods 7011 are both passed through the placement plate 5, and the positioning block 7013 is moved to the outside of the limit block 7012, so that the limit block 7012 can limit and position the positioning block 7013. The nut 7014 is rotated to abut against the bottom of the positioning block 7013, so that the positioning block 7013 is limited. At this time, the outer end of the ball 7016 is fitted with the bottom of the placement plate 5, so that the movable frame 6 can be limited, so that it cannot move up and down, and will not hinder the lateral movement of the movable frame 6. After the impact force acts on the outside of the movable frame 6, it can squeeze the corresponding air spring 703 for compression. Under the compression energy absorption action of the gas medium inside the air spring 703, the impact energy can be absorbed and weakened, reducing the energy transmission distance and size, and thus protecting the industrial instrument body 1 and the internal parts.

[0054] (2) When performing visible surface protection, compressed air enters the interior of the bellows 903 through the air inlet pipe 902, and is then transported to the interior of the air outlet pipe 901. Through the transmission function of the first air duct 904 and the second air duct 906, the air is blown out through the inclined pipe 905 and the parallel pipe 907, thereby forming an air curtain on the surface of the cover plate 801 that can prevent liquid from dripping. At the same time, it can also play a dust-proof role, so that dust can be blown away, and it can also prevent liquid from continuing to adhere to the surface of the cover plate 801, prevent the generation of water stains, and prevent corrosive chemicals from corroding the surface of the cover plate 801, so that the industrial instrument body 1 can be clearly viewed by external staff through the visible surface of the cover plate 801.

[0055] (3) When it is necessary to open the cover 801 to perform simple maintenance or inspection and debugging on the industrial instrument body 1, push the grip plate 8029 upward, so that the limit piece 8030 moves upward and pushes the first round table 8031 to move upward, so that the top of the first round table 8031 passes over the corresponding two triangular plug blocks 8024, so that the first round table 8031 and the second round table 8032 are both located inside the connecting tube 8021, and move the grip plate 8029 downward so that the inclined surface of the first round table 8031 contacts the triangular plug block 8024, and the triangular plug block 8024 is driven away from the first round table 8031 by the action of the inclined surface. 1 and compress the elastic member 8023. Under the elastic force recovery action of the elastic member 8023, pressure is applied to the first circular platform 8031 through the triangular plug block 8024, so that the first circular platform 8031 can fit with the second circular platform 8032. When the triangular plug block 8024 passes over the first circular platform 8031, the elastic force recovery action of the elastic member 8023 can drive the triangular plug block 8024 to move to both sides of the second circular platform 8032, so that the second circular platform 8032 can be normally moved out from the interior of the corresponding connecting tube 8021, so that the cover plate 801 can be normally opened.

[0056] Compared with the prior art, the industrial automation instrument protection device, through the limit block 7012 to the positioning block 7013 plays a limiting and positioning role, and through the outer end of the ball 7016 and the bottom of the placement plate 5, the extension plate 7015 can play a limiting role and can also reduce the friction between the bottom of the placement plate 5 under the action of the ball 7016, so that the movable frame 6 can move laterally. When it is impacted, under the action of the air spring 703, the compression energy absorption characteristics of the internal gas medium can be used to absorb and weaken the impact energy, reducing the energy transmission distance and size, so as to protect the industrial instrument body 1 and the internal parts. The transmission effect causes the compressed air to be transported to the interior of the first air duct 904 and the second air duct 906, so that it can be blown out through the inclined tube 905 and the parallel tube 907. The blown air can be used to form an air curtain on the surface of the cover plate 801 to prevent liquid from dripping, thereby protecting the visible surface of the cover plate 801. At the same time, it can also have a dust-proof effect, so that dust around the surface can be blown away, and water or chemicals can be prevented from adhering to the visible surface of the cover plate 801 for a long time, thereby avoiding the generation of water stains and the occurrence of corrosion problems, and solving the problem that most existing protective devices do not have the function of absorbing impact energy and cannot block dripping liquid. During long-term use, water stains or corrosion will appear on the visible surface, resulting in reduced clarity.
