Description

Technical Field

[0001] This utility model relates to the field of chemical technology, and in particular to a chemical safety isolation device. Background Technology

[0002] Chemical industry is an abbreviation for "chemical process", "chemical industry", "chemical engineering", etc. Any technology that uses chemical methods to change the composition or structure of substances or synthesize new substances falls under the category of chemical production technology, also known as chemical process. The resulting products are called chemicals or chemical products.

[0003] However, in the existing technology, non-foldable isolation devices are often relatively fixed in shape and large in size, making it difficult to flexibly adjust their position during loading and unloading. This makes it difficult for them to pass through narrow passages, doorways, or be loaded into transport containers of specific shapes. In the emergency response to chemical accidents, it is necessary to quickly set up isolation areas to prevent the accident from spreading further. If the isolation device is not easy to fold, it may delay the implementation of emergency isolation measures. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing non-foldable isolation devices often have a fixed shape and large size, making it difficult to flexibly adjust their position during loading and unloading. Therefore, this invention proposes a chemical safety isolation device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a chemical safety isolation device, comprising two support rods, two fixing rods symmetrically fixedly connected to the side walls of the two support rods, and a driving mechanism installed on the side walls of the two support rods;

[0006] The driving mechanism includes two mounting frames and multiple connecting plates. Drive wheels are rotatably connected to the inner side of the mounting frames. Steel cables are sleeved on the outer surfaces of the two drive wheels. Connecting blocks are fixedly connected to the outer surfaces of the steel cables. Movable frames are fixedly connected to the top and bottom outer surfaces of the connecting plates. The center of the side wall of one of the connecting plates is fixedly connected to the connecting block. A central rod is fixedly connected to the side wall of the movable frame. Rollers are rotatably connected to the top and bottom of the central rod.

[0007] Preferably, one side of the support rod is provided with multiple folding isolation plates, and one of the folding isolation plates is fixedly connected to two connecting plates.

[0008] Preferably, a limiting groove is formed on the inner side of the fixing rod, and the roller is located inside the limiting groove.

[0009] Preferably, the width of the notch on one side of the limiting groove is less than the length of the central rod.

[0010] Preferably, a support block is fixedly connected to the bottom of the support rod.

[0011] Preferably, a knob is fixedly connected to the top of one of the drive wheels.

[0012] Preferably, the two mounting brackets are fixedly connected to the side walls of the two support rods, respectively.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the design of the folding isolation panel is to drive the drive wheel to rotate through the knob, thereby driving the steel cable to move, pushing the connecting block and connecting plate to move synchronously, so as to realize the unfolding of the isolation panel. The folding isolation panel is usually in a folded state to save space, but with the movement of the steel cable, multiple isolation panels can be unfolded in coordination to form an effective isolation barrier. This unfolding process not only plays a physical isolation role, but also effectively prevents liquid splashing or particulate matter diffusion, ensuring the safety of operators. The designed storage mechanism allows the isolation panel to be quickly retracted when not in use, saving space and keeping the operating area clean.

[0015] 2. In this utility model, the precise cooperation between the roller and the limiting groove ensures the smooth and accurate movement of the connecting plate during operation. The roller slides freely within the limiting groove and is strictly controlled by the boundary of the groove wall, effectively limiting the excessive movement of the connecting plate and preventing it from deviating from the predetermined track. This control mechanism not only improves the stability and smoothness of the unfolding process of the folding partition plate, but also enhances the reliability of the system and avoids possible malfunctions or misalignments. The synergistic effect of the roller and the limiting groove ensures that the movement of the connecting plate is always kept within the predetermined range, thereby guaranteeing efficient and accurate working results. This structural design is simple and efficient, and is suitable for mechanical systems that require precise position control, ensuring the stable operation of the equipment under various working conditions.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1-4 As shown, this utility model provides a chemical safety isolation device, including two support rods 2, two fixing rods 4 are symmetrically fixedly connected to the side walls of the two support rods 2, and a driving mechanism 3 is installed on the side walls of the two support rods 2;

[0024] The drive mechanism 3 includes two mounting brackets 31 and multiple connecting plates 36. Drive wheels 33 are rotatably connected to the inner side of the mounting brackets 31. Steel cables 32 are sleeved on the outer surfaces of the two drive wheels 33. Connecting blocks 34 are fixedly connected to the outer surfaces of the steel cables 32. Movable frames 38 are fixedly connected to the outer surfaces of the top and bottom of the connecting plates 36. The center of the side wall of one of the connecting plates 36 is fixedly connected to the connecting block 34. A central rod 37 is fixedly connected to the side wall of the movable frame 38. Rollers 39 are rotatably connected to the top and bottom of the central rod 37.

[0025] The specific settings and functions of this embodiment will be described in detail below. When the user turns knob 35, it directly drives one of the drive wheels 33 to rotate. The rotation of the drive wheel 33 will drive the steel cable 32 to move. As the steel cable 32 is pulled, the movement of the steel cable 32 causes the connecting block 34 to move under its drive.

[0026] The connecting block 34 begins to move through its interaction with the steel cable 32. As the connecting block 34 moves with the steel cable 32, it causes the connecting plate 36 connected to it to move as well. The movement of the connecting plate 36 pushes the unfolding of the folding partition plate 1.

[0027] The folding barrier 1 is normally folded to save space, but once the steel cable 32 moves, the movement of the connecting block 34 and the connecting plate 36 will force these folding barrier 1 to gradually unfold. The unfolding process of the folding barrier 1 is gradual; each time a barrier is unfolded, it will cause another connecting plate 36 to move accordingly. This synchronicity and continuity of movement allows multiple folding barrier 1 to open in a coordinated manner, forming a continuous isolation barrier.

[0028] At the same time, the unfolding of the folding isolation plate 1 is not only for physical isolation, but also effectively prevents liquid splashing or particulate matter diffusion in the chemical environment, thereby ensuring the safety of operators.

[0029] Furthermore, the folding partition 1 is designed for excellent retraction. When isolation is not required, the folding partition 1 can be retracted by contacting the bolts used to connect the connecting block 34 and the connecting plate 36, saving space and keeping the operating area tidy and unobstructed. This retraction mechanism allows the partition to be quickly unfolded when needed and completely folded away when not in use, providing great convenience.

[0030] Example 2: Figure 1 and Figure 2 As shown, multiple folding partition plates 1 are provided on one side of the support rod 2, and one folding partition plate 1 is fixedly connected to two connecting plates 36. A limiting groove 41 is opened on the inner side of the fixing rod 4, and the roller 39 is located inside the limiting groove 41. The width of the notch on one side of the limiting groove 41 is smaller than the length of the center rod 37. A support block 21 is fixedly connected to the bottom of the support rod 2. A knob 35 is fixedly connected to the top of one of the drive wheels 33. Two mounting brackets 31 are fixedly connected to the side walls of the two support rods 2 respectively.

[0031] The overall effect of this embodiment is that when the connecting block 34 moves the connecting plate 36, a movable frame 38 is provided on the side wall of the connecting plate 36. As the connecting plate 36 moves, the movable frame 38 also moves synchronously. During the movement, a roller 39 is installed on the central rod 37 at one end of the movable frame 38. This roller 39 slides freely within the limiting groove 41 and cooperates with the shape and position of the limiting groove 41 to form a precise guiding and limiting mechanism.

[0032] The coordinated action of the rollers 39 and the limiting groove 41 not only ensures the smoothness and precision of the connecting plate 36 during movement, but also effectively limits its excessive movement, preventing it from deviating from the predetermined track. In particular, during the movement of the connecting plate 36, the trajectory of the rollers 39 is strictly controlled by the boundary of the limiting groove 41. This control method keeps the movement of the connecting plate 36 within a predetermined range, ensuring the stability and smoothness of the folding partition plate 1 during unfolding.

[0033] Furthermore, the design of roller 39 ensures that it cannot detach from the side wall of the fixing rod 4. This non-detachable structure guarantees the system's stability under any circumstances, avoiding potential malfunctions or misalignments. This precise coordination and control, especially when the folding partition 1 is unfolded, ensures that it remains in the predetermined position, thereby achieving efficient and reliable operation.

[0034] The device's operation and working principle are as follows: Twisting or rotating the device drives one of the drive wheels 33 to rotate. When the drive wheel 33 rotates, it moves the steel cable 32. The movement of the steel cable 32 causes the connecting block 34 to move. As the connecting block 34 moves with the steel cable 32, it moves the connecting plate 36 connected to it. During this process, the connecting plate 36 moves the connected folding partition plate 1, causing it to unfold. As the folding partition plate 1 unfolds, it also moves another connecting plate 36. Thus, when one connecting plate 36 moves with the connecting block 34, not only do multiple folding partition plates 1 gradually unfold, but each connecting plate 36 also moves sequentially.

[0035] As the steel cable 32 moves, multiple folding isolation panels 1 are deployed, thereby isolating the chemical environment and preventing liquid splashes that could injure operators. Simultaneously, the folding isolation panels 1 are retractable, facilitating observation and operation by operators under safe conditions, and can play an isolating role during the reaction process.

[0036] When the connecting block 34 moves the connecting plate 36, the movable frame 38 on the side wall of the connecting plate 36 also moves synchronously. During the movement, the roller 39 on the center rod 37 at one end of the movable frame 38 rolls within the limiting groove 41. The roller 39 and the limiting groove 41 cooperate with each other, not only to guide the movement but also to limit the movement of the connecting plate 36, ensuring that the roller 39 will not detach from the side wall of the fixed rod 4, thereby ensuring that the folding partition plate 1 can be unfolded smoothly.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
