Description

Technical Field

[0001] This utility model relates to the field of dust control equipment technology, specifically a dust cover for GIS equipment construction. Background Technology

[0002] Dust covers for GIS equipment construction are specialized devices used to protect gas-insulated switchgear from dust contamination during installation. They are typically made of transparent, flexible materials (such as PVC film or TPU) and equipped with elastic sealing cuffs and inflatable support structures. They effectively prevent external pollutants from entering the equipment, ensuring the installation quality and long-term operational reliability of the GIS equipment.

[0003] Currently, dust covers are needed during the construction of GIS equipment to prevent dust and other fine particles from entering the equipment and affecting its normal operation. Existing dust covers have certain effects in dust and moisture prevention, but they have problems such as insufficient structural stability and poor environmental adaptability, which affect construction efficiency and safety.

[0004] Existing dust covers are prone to tipping over or deforming in strong winds or mechanical vibrations due to their poor support and weak wind resistance. This can cause the entire device to collapse, affecting the dust protection effect. Furthermore, they are easily displaced by external wind forces, which can damage the seal and render the dust protection ineffective, making it difficult to ensure a clean construction environment.

[0005] Therefore, this utility model provides a dust cover for GIS equipment construction to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this utility model is to provide a dust cover for GIS equipment construction, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A dust cover for GIS equipment construction includes a supporting airbag frame. The outer wall of the supporting airbag frame is fixedly covered with a dust cover, and the bottom surface of the supporting airbag frame is fixedly connected to a ground film. The supporting airbag frame, the dust cover, and the ground film form a relatively closed space to prevent dust, sand, debris, etc. from the external environment from entering.

[0009] A door curtain is fixedly installed on one side of the dust cover to facilitate the entry and exit of construction personnel. The outer wall of the dust cover has a pass-through port for passing small tools and accessories, and a sealing curtain is fixedly installed thereon. A sealing rope is slidably connected to one end of the sealing curtain. By pulling the sealing rope, the opening at one end of the sealing curtain can be tightened to enhance the dustproof effect.

[0010] The inner cavity of the dust cover is equipped with an expansion component to prevent the top of the dust cover from deforming or collapsing, and the top surface of the ground film is fixedly equipped with a support component to support the entire fixing device.

[0011] As a further embodiment of this utility model, the extension component includes a fixed frame located inside the dust cover. The fixed frame has two fixed frames, and a fixed plate is installed on the side of each fixed frame that is far apart from the other. A connecting frame is fixedly installed on the side of each fixed frame and the fixed plate that is close to the other.

[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] Please see Figure 1 , Figure 2 In this embodiment of the present invention, a dust cover for GIS equipment construction includes a supporting airbag frame 1, a dust cover 2 fixedly covering the outer wall of the supporting airbag frame 1, and a ground film 3 fixedly connected to the bottom surface of the supporting airbag frame 1. The supporting airbag frame 1, the dust cover 2 and the ground film 3 form a relatively closed space to block dust, sand, debris and other objects from the external environment from entering, providing a clean operating environment for GIS equipment construction and preventing pollutants from affecting the installation and performance of the equipment.

[0031] A door curtain 4 is fixedly installed on one side of the dust cover 2 to facilitate the entry and exit of construction personnel. The outer wall of the dust cover 2 has a pass-through port for passing small tools and accessories, and a sealing curtain 5 is fixedly installed thereon. A sealing rope 6 is slidably connected inside one end of the sealing curtain 5. By pulling the sealing rope 6, the opening at one end of the sealing curtain 5 can be tightened to enhance the dustproof effect.

[0032] The inner cavity of the dust cover 2 is equipped with an extension component 7 to prevent the top of the dust cover 2 from deforming or collapsing, and the top surface of the ground film 3 is fixedly equipped with a support component 8 to support the entire fixing device.

[0033] Specifically, the dust cover 2 is made of PVC film, which has good transparency, allowing construction workers to operate inside while external personnel can clearly observe the internal situation. It also provides good dust and moisture protection, effectively preventing external dust and debris from entering the internal space. The curtain 4 consists of two pieces, which are sealed together with Velcro to ensure that construction workers can enter and exit quickly and close afterward, reducing the chance of dust entering. The sealing curtain 5 allows small tools and accessories to be passed without fully opening the dust cover 2, reducing the risk of dust protection failure and ensuring the airtightness of the dust cover 2 during construction.

[0034] Please see Figure 2 , Figure 3 , Figure 4 , Figure 5 The extension component 7 includes a fixed frame 701 located inside the dust cover 2. There are two fixed frames 701, and a fixed plate 702 is installed on the side of the two fixed frames 701 that is far apart. A connecting frame 703 is fixedly installed on the side of the fixed frame 701 and the fixed plate 702 that is close to each other. A movable plate 704 is slidably connected to the bottom surface of the connecting frame 703. A folding rod 705 for opening the top of the dust cover 2 is rotatably installed on the side of the two movable plates 704 that is close to each other, and the two folding rods 705 are rotatably connected by a pin.

[0035] Specifically, the ends of the two folding rods 705 that are far apart are rotatably connected to gears 706 via pins, and a rack 707 for driving the folding rods 705 to rotate is fixedly installed on the outer wall of the moving plate 704, and the rack 707 meshes with the gears 706.

[0036] Each movable plate 704 has a connecting frame 703 passing through its top end and a sliding block 708 fixedly connected thereto. An electric push rod 709 for providing moving power is fixedly installed on the top surface of the connecting frame 703, and the electric push rod 709 is fixedly connected to the sliding block 708.

[0037] Specifically, the connecting bracket 703 has a sliding groove inside for providing sliding for the sliding block 708, and the sliding block 708 is located in the sliding groove;

[0038] The inner cavity of the fixed frame 701 is rotatably connected to the rotating rod 710 via a bearing. The outer wall of the rotating rod 710 is fixedly wrapped with a support plate 711 for support. One end of the support plate 711 passes through two connecting frames 703 in sequence and is fixedly connected to the fixed plate 702.

[0039] Specifically, the support plate 711 is made of aluminum alloy plate. When unfolded, it can use the rigidity of the metal itself to support the dust cover 2. When stored, it can be rolled up with the rotating rod 710 for easy storage.

[0040] Please see Figure 1 , Figure 6 The support assembly 8 includes a movable rod 801, which is threaded to the bottom surface of the fixed plate 702. The bottom end of the movable rod 801 is slidably fitted with a support column 802. There are two support columns 802 in total, and each support column 802 is equipped with a fastening component at its top to prevent the support assembly 8 from sliding accidentally. The bottom end of the bottom support column 802 is threaded to a base 803, and the base 803 is fixedly connected to the ground film 3.

[0041] The fastening assembly includes a threaded sleeve 804, which is fixedly sleeved on the top outer wall of the support column 802, and a fastening tube 805 for fixing is threaded on the outer wall of the threaded sleeve 804.

[0042] Specifically, the outer wall of the fastening tube 805 is equipped with an anti-slip block. The tops of both the threaded sleeve 804 and the fastening tube 805 are tapered, and the top of the threaded sleeve 804 is provided with multiple notches. When the fastening tube 805 is rotated, it moves down along the threaded sleeve 804. Utilizing the tapered features and notches of both, the threaded sleeve 804 shrinks inward during the rotation and downward movement of the fastening tube 805, thereby achieving the effect of clamping and fixing. It can stably maintain the clamping state, ensure the clamping force is long-lasting, and prevent loosening. At the same time, the clamping force can be flexibly adjusted by controlling the number of rotations and the tightening degree of the fastening tube 805, and the height of the support component 8 can be changed to adapt to different working requirements.

[0043] The support assembly 8 also includes a connector 806, which is fixedly installed on the outer wall of the support airbag frame 1. A guy rope 807 is fixedly connected to the outer wall of the connector 806 to enhance the wind resistance of the device. A ground nail 808 is fixedly inserted into the bottom end of the guy rope 807 through a hanging ring.

[0044] Please see Figure 2 The top inner wall of the dust cover 2 is fixedly installed with a Velcro 9, and the Velcro 9 is fixedly adhered to the bottom surface of the fixing plate 702. The inner wall of the airbag frame 1 is fixedly connected with a fixing ring 10 for connecting the support component 8, and the support component 8 is located inside the fixing ring 10.

[0045] The working principle of this utility model is as follows:

[0046] When this utility model is used, firstly, the supporting airbag frame 1 is inflated to form a stable arched structure, which together with the PVC dust cover 2 and the bottom ground film 3 constitutes a nearly completely enclosed construction space, which can effectively block external dust, sand and other pollutants, and provide a clean environment for the installation of GIS equipment.

[0047] After the dust cover 2 is installed, the electric actuator 709 is activated to drive the sliding block 708 to move in the sliding groove of the connecting frame 703, thereby displacing the moving plate 704. Then, through the meshing transmission of the rack 707 and the gear 706, the folding rod 705 is unfolded or retracted. At the same time, the unfolding of the folding rod 705 drives the fixed plate 702 to move, thereby pulling the aluminum alloy support plate 711 to unfold, providing rigid support for the top of the dust cover 2 and preventing deformation and collapse.

[0048] Then rotate the moving rod 801 and install it on the bottom surface of the fixed plate 702. Then unfold the moving rod 801 and the support column 802 in sequence. Then, by rotating the fastening tube 805, and using its tapered fit and notch design with the threaded sleeve 804, the support column 802 is lifted and locked. Then, the bottom support column 802 is threaded into the base 803, thereby using the support assembly 8 to support and fix the airbag frame 1 and the dust cover 2.

[0049] Then, the guy rope 807 is stretched to a suitable position and fixed to the ground by ground nails 808 to form a multi-point anchoring system, which enhances the wind resistance of the device.

[0050] Finally, construction workers can enter and exit through the door curtain 4, which is attached by Velcro. The transfer of tools is accomplished through the cooperation of the sealing curtain 5 and the sealing rope 6, which minimizes the opening area. Furthermore, the transparent PVC material of the dust cover 2 ensures both construction visibility and good sealing performance. The overall device can achieve the integrated functions of rapid construction, stable support, and reliable dust prevention, effectively improving the quality and efficiency of GIS equipment construction.

[0051] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
