Description

Technical Field

[0001] This utility model relates to the field of safety barriers for isolation equipment, specifically a safety barrier for isolation equipment with explosion-proof gas shut-off function. Background Technology

[0002] The safety barrier of the isolation equipment itself has an explosion-proof gas shut-off function; through its design characteristics, the entire barrier can control the explosion within the enclosure through the explosion-proof housing assembly in the event of a circuit fire or explosion, thereby reducing the scope of the explosion hazard and protecting the safety of personnel and equipment.

[0003] Safety barriers play a crucial role in electrical explosion protection. They limit current and voltage to ensure stable power transmission and prevent potential explosion risks caused by electrical sparks. Safety barriers are divided into two types: Zener and isolation. Zener safety barriers limit current through internal components such as fast-blow fuses, current-limiting resistors, and Zener diodes, while isolation safety barriers provide a higher level of safety protection by physically isolating the input, output, and power supply.

[0004] According to the invention patent application No. 201710937797.1, an explosion-proof isolation safety barrier that is easy to install is available. This barrier has advantages such as easy installation of the isolation chamber safety barrier and faster installation speed. However, after installation, the safety barrier is easily affected by the installation location and area, and it is not convenient to adjust the isolation height in real time, which limits the use of the safety barrier. Therefore, it is necessary to propose an isolation equipment safety barrier with explosion-proof gas cut-off function to solve the above-mentioned problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a safety barrier for isolation equipment with explosion-proof gas shut-off function, which has the advantages of conveniently adjusting the height of the safety barrier according to usage requirements, and solves the problem of inconvenient real-time adjustment of isolation height in the prior art.

[0006] To achieve the above-mentioned purpose of conveniently adjusting the height of the safety barrier according to usage requirements, this utility model provides the following technical solution: a safety barrier for isolation equipment with explosion-proof gas shut-off function, including an adjusting cylinder and a safety barrier body, both ends of the adjusting cylinder are provided with fixed cylinders, the outside of the fixed cylinder is provided with a positioning component, a first lifting ring is slidably installed on the outer surface of the adjusting cylinder, a connecting post is provided on one side of the first lifting ring, a positioning insert is provided on one side of the connecting post, and a height adjusting component is movably installed inside the adjusting cylinder;

[0007] The height adjustment assembly includes a rotating drum, which is movably mounted on the top of the fixed drum. A threaded rotating rod is provided at the bottom of the rotating drum. A second lifting ring is threadedly connected to the outer surface of the threaded rotating rod. A plug-in rod is fixedly connected to the outer surface of the second lifting ring. A limit slider is provided on one side of the plug-in rod.

[0008] Furthermore, the positioning component includes a collar, and the outside of the fixed cylinder is provided with a collar. A first positioning plate and a second positioning plate are respectively provided on the left and right sides of the collar, and positioning holes are opened on the front of the first positioning plate and the second positioning plate.

[0009] Furthermore, a limiting groove is formed on the outside of the adjusting cylinder, and a plug rod is slidably installed inside the limiting groove.

[0010] Furthermore, the limiting slider passes through the limiting groove and extends to the outer surface of the adjusting cylinder, and a first lifting ring is provided on the outside of the limiting slider.

[0011] Furthermore, a safety barrier body is provided on the front side of the adjusting cylinder, and a positioning groove is provided at the bottom of the safety barrier body, with a positioning insert plate inserted into the positioning groove.

[0012] Furthermore, the bottom of the rotating drum is fixedly connected to the top of the threaded rotating rod, and the second lifting ring is fixedly connected to the plug rod and the limiting slider.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This safety barrier with explosion-proof gas shut-off function, through the setting of a height adjustment component, allows for operation by rotating a rotating drum, which in turn drives a threaded rod to rotate. Due to the limiting effect of the limiting groove on the plug rod and the limiting slider, the second lifting ring is threadedly connected to the outer surface of the threaded rod. The second lifting ring moves up and down at the outer surface of the adjusting drum. When the second lifting ring moves up and down, it drives the first lifting ring to move up and down through the plug rod and the limiting slider, ultimately achieving vertical height adjustment of the safety barrier body. The operation steps are simple, solving the problem of inconvenient real-time adjustment of the isolation height in the prior art.

[0015] This safety barrier with explosion-proof gas shut-off function uses a positioning component. During use, the collar is fixed to the outer surface of the adjusting cylinder, and bolts are inserted into the positioning holes, thereby fixing the first and second positioning plates to the wall surface at the place of use. The fixing process of the adjusting cylinder is simple. Furthermore, by inserting three sets of positioning plates into the positioning slots, the safety barrier body can be placed on top of the positioning plates, which facilitates the removal and maintenance of the safety barrier body.

[0021] 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.

[0022] Please see Figure 1-4 The safety barrier of the isolation equipment with explosion-proof gas cut-off function in this embodiment includes an adjusting cylinder 1 and a safety barrier body 2. Both ends of the adjusting cylinder 1 are provided with fixed cylinders 3. The fixed cylinder 3 is provided with a positioning component 4 on its outside. A first lifting ring 5 is slidably installed on the outer surface of the adjusting cylinder 1. A connecting post 6 is provided on one side of the first lifting ring 5. A positioning insert 7 is provided on one side of the connecting post 6. A height adjusting component 9 is movably installed inside the adjusting cylinder 1.

[0023] The height adjustment assembly 9 includes a rotating drum 901. The rotating drum 901 is movably mounted on the top of the top fixed cylinder 3. A threaded rotating rod 902 is provided at the bottom of the rotating drum 901. A second lifting ring 903 is threadedly connected to the outer surface of the threaded rotating rod 902. A plug-in rod 904 is fixedly connected to the outer surface of the second lifting ring 903. A limit slider 905 is provided on one side of the plug-in rod 904.

[0024] In the implementation of the case, by setting up the height adjustment component 9, when in use, by rotating the rotating drum 901, the rotating drum 901 will drive the threaded rotating rod 902 to rotate. Due to the limiting effect of the limiting groove 10 on the plug rod 904 and the limiting slider 905, the second lifting ring 903 is threadedly connected to the outer surface of the threaded rotating rod 902. The second lifting ring 903 moves up and down at the outer surface of the adjusting cylinder 1. When the second lifting ring 903 moves up and down, it drives the first lifting ring 5 to move up and down through the plug rod 904 and the limiting slider 905. Finally, it drives the safety barrier body 2 to adjust its height in the vertical direction. The operation steps are simple and solve the problem of inconvenient real-time adjustment of the isolation height in the background technology.

[0025] In the implementation of the case, by setting the positioning component 4, when in use, the collar 401 is fixed to the outer surface of the adjusting cylinder 1 and is inserted into the positioning hole 404 by bolts, thereby fixing the first positioning plate 402 and the second positioning plate 403 to the wall surface of the application site. The fixing steps of the adjusting cylinder 1 are simple.

[0026] In the implementation of the case, the three sets of positioning plates 7 are inserted into the positioning slots 8, which allows the safety barrier body 2 to be placed on top of the positioning plates 7, making it convenient to remove and maintain the safety barrier body 2.

[0027] When implementing this procedure, please follow these steps:

[0028] 1) First, fix the adjusting cylinder 1 in place at the application location using the positioning component 4;

[0029] 2) Then place the safety barrier body 2 on the positioning plate 7 for use;

[0030] 3) Then adjust the height of the first lifting ring 5 and the second lifting ring 903 using the height adjustment component 9;

[0031] 4) Finally, the height of the safety barrier body 2 is adjusted by the first lifting ring 5.

[0032] In summary, this safety barrier with explosion-proof gas shut-off function, through the setting of the height adjustment component 9, allows for the rotation of the rotating drum 901 during use. The rotating drum 901 drives the threaded rotating rod 902 to rotate. Due to the limiting effect of the limiting groove 10 on the plug rod 904 and the limiting slider 905, the second lifting ring 903 is threadedly connected to the outer surface of the threaded rotating rod 902. The second lifting ring 903 moves up and down at the outer surface of the adjusting cylinder 1. When the second lifting ring 903 moves up and down, it drives the first lifting ring 5 to move up and down through the plug rod 904 and the limiting slider 905, ultimately achieving the vertical height adjustment of the safety barrier body 2. The operation steps are simple, solving the problem of inconvenient real-time adjustment of the isolation height in the prior art.

[0033] Furthermore, by setting the positioning component 4, during use, the collar 401 is fixed to the outer surface of the adjusting cylinder 1 and is bolted into the positioning hole 404, thereby fixing the first positioning plate 402 and the second positioning plate 403 to the wall surface of the application site, simplifying the fixing steps of the adjusting cylinder 1; and by inserting the three sets of positioning plates 7 into the positioning groove 8, the safety barrier body 2 can be placed on top of the positioning plates 7, facilitating the removal and maintenance of the safety barrier body 2.
