Abstract
Description
Technical Field
[0001] This utility model relates to the field of safety isolation panels, and more particularly to a chemical safety isolation panel. Background Technology
[0002] As a key safety facility in chemical production environments, chemical safety barriers effectively block safety threats such as harmful gases, dangerous liquid splashes, high-temperature radiation, and accidental explosions that may occur during chemical production through physical isolation. This provides a reliable protective barrier for operators and surrounding equipment, thereby greatly reducing potential casualties and property losses in the event of an accident.
[0003] Under current technology, most chemical safety isolation panels are immovable and can only be manually moved, resulting in poor portability. Furthermore, isolation panels with rollers are easily pushed open by external forces during explosions or other impacts due to the constant rolling of the rollers, leading to poor stability. Therefore, a new type of chemical safety isolation panel is proposed to solve the above problems. Utility Model Content

[0007] The extension frame is T-shaped, and the baffle plate is arc-shaped.
[0008] As a further description of the above technical solution:
[0009] The locking assembly includes a protective box, the right surface of which is fixedly connected to the left surface of the passive rod, and a locking block is slidably connected to the inner wall of the protective box.
[0010] As a further description of the above technical solution:
[0011] The right surface of the locking block has a slope near the front end, and a guide rod is fixedly connected to the left surface of the locking block. A pull plate is fixedly connected to the left surface of the guide rod.
[0012] As a further description of the above technical solution:
[0013] A reset spring is fixedly connected to the left surface of the lock block, and the left end of the reset spring is fixedly connected to the inner wall of the protective box.

[0020] This utility model has the following beneficial effects:
[0021] 1. In this utility model, the rollers, fixing components, and blocking plates enable the device to be moved quickly to the location requiring isolation and protection during use. By stepping on the pedal, the drive plate moves the extension frame to support the ground, thus fixing the device to the ground. In the event of an explosion or other external force, the blocking plate can be better secured, enhancing the stability of the device. The operator can curl up on the support plate, reducing the impact area and making the safety of the protected personnel stronger.
[0022] 2. In this utility model, the buffer component ensures that when a heavy object is lifted by the explosion impact and hits the isolation plate in the event of an accident such as a chemical explosion, it will first hit the buffer plate. The buffer spring behind the buffer plate will cause the energy of the heavy object to be consumed more quickly, reducing the force of the impact on the blocking plate and enhancing the protective effect of the device.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Reference Figure 1 - Figure 3This utility model provides an embodiment of a chemical safety isolation plate, comprising a barrier plate 1 with an acid-resistant coating, the surface of which is used to block splashes of chemical liquids such as acids to protect the operator behind. A buffer assembly 2 is provided on the front surface of the barrier plate 1 to mitigate explosions or other external forces. A support plate 4 is fixedly connected to the lower end of the inner wall of the barrier plate 1 to support the operator, allowing the operator to curl up behind the barrier plate 1 to reduce the impact area and protect the feet. A directional wheel 6 is fixedly connected to the lower surface of the support plate 4 to facilitate device movement. A fixing assembly 5 is provided on the lower surface of the support plate 4 to support the ground and increase the contact area with the ground. The fixing assembly 5 includes a fixing plate 51 for fixing a housing 52. The upper surface of the fixing plate 51 is fixedly connected to the lower surface of the support plate 4, and the lower surface of the fixing plate 51 is fixedly connected to a housing 52 for accommodating an extension frame 53. The inner wall of the housing 52 slides... The device is connected to an extension frame 53 that extends out of the housing 52 and supports it on the ground to increase friction with the ground and prevent the device from being moved accidentally by external forces. After extending, the extension frame 53 is flush with the directional wheel 6. The left surface of the housing 52 is rotatably connected to a passive rod 54 that supports the drive rod 55 and is driven by the drive rod 55 to swing. The inner wall of the passive rod 54 is hinged to a drive rod 55 that drives the passive rod 54 to swing. The inner wall of the drive rod 55 is rotatably connected to the left surface of the extension frame 53. The front end of the outer wall of the drive rod 55 is fixedly connected to a pedal 56 for easy operation by the operator, which drives the extension frame 53 by stepping on it and reduces the time required for the fixing component 5 to take effect. The outer wall of the housing 52 is provided with a locking component 7 for locking the passive rod 54 to prevent the need to continuously step on the pedal 56 to take effect for the fixing component 5. The rear surface of the blocking plate 1 is fixedly connected to a handle 3 for easy movement of the device by the operator.
[0031] Reference Figure 1 - Figure 3The extension frame 53 is T-shaped, which increases the contact area between the extension frame 53 and the ground without affecting the rolling of the rollers. The baffle plate 1 is arc-shaped, so that when impacted, the arc-shaped structure can disperse the impact force along the arc surface, avoiding concentration at a certain point and enhancing the protective effect. The locking assembly 7 includes a protective box 71 for protecting the internal structure. The right surface of the protective box 71 is fixedly connected to the left surface of the passive rod 54. The inner wall of the protective box 71 is slidably connected to a locking block 73 for inserting into the slot 76 to fix the passive rod 54. The right surface of the locking block 73 is close to the left surface of the left side of the passive rod 54. A slope is provided near the front end to limit the locking block 73 in one direction. In an emergency, the device can be fixed by stepping on the pedal 56 without pulling the pull plate 75, reducing operation time. A guide rod 74 is fixedly connected to the left surface of the locking block 73 to transmit the force on the pull plate 75 to the locking block 73. A pull plate 75 is fixedly connected to the left surface of the guide rod 74 for easy pulling by the operator. A return spring 72 is fixedly connected to the left surface of the locking block 73 to automatically reset the locking block 73 after movement. The left end of the return spring 72 is fixedly connected to the inner wall of the protective box 71.
[0032] Reference Figure 1 - Figure 3 The left surface of the housing 52 is provided with a slot 76 for accommodating the locking block 73. The outer wall of the locking block 73 is inserted into the inner wall of the slot 76. The buffer assembly 2 includes a buffer plate 21 for blocking the explosive impact or other heavy objects on the outermost layer. The inner wall of the buffer plate 21 is slidably connected to a connecting rod 22 for connecting the stop block 23 and the stop plate 1 and supporting the sliding of the buffer plate 21. The rear surface of the connecting rod 22 is fixedly connected to the front surface of the stop plate 1. The front surface of the connecting rod 22 is fixedly connected to a stop block 23 for preventing the buffer plate 21 from falling off. The rear surface of the stop plate 1 is fixedly connected to a buffer spring 24 for consuming the impact energy through its own elastic deformation. The rear end of the buffer spring 24 is fixedly connected to the front end of the stop plate 1.
[0033] Working principle: First, hold handle 3 and push the entire device to the desired position. In case of an accident, simply step on pedal 56. Pedal 56 drives drive rod 55 to swing, which in turn moves extension frame 53 downward. The swing of drive rod 55 causes driven rod 54 to swing. When drive rod 55 and driven rod 54 swing into a straight line, extension frame 53 is supported on the ground. At this time, directional wheel 6 is still on the ground and, together with fixed component 5, blocks the impact. At the same time, locking block 73 is inserted into slot under the action of internal return spring 72. Inside 76, the device is fixed in place, and the operator can stand on the support plate 4 to avoid the impact, avoiding the situation where the feet are unprotected when standing on the ground. When the heavy object is carried away by the impact of the chemical explosion, the heavy object first contacts the buffer plate 21. The buffer plate 21 moves backward, causing the buffer spring 24 to deform. During the deformation process, the buffer spring 24 will consume the impact energy of the heavy object. After the impact ends, pull the pull plate 75. The pull plate 75 drives the guide rod 74 to move, causing the locking block 73 to disengage from the slot 76, resetting the fixing component 5, and completing all operations.
[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
