DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0033] The present invention provides Figures 1 to 9A portable dustproof shed for installing GIS equipment is shown, comprising two support plates 1, the two support plates 1 are vertically symmetrically distributed, the front sides of the two support plates 1 are hinged with movable doors 2, the rear sides of the two support plates 1 are hinged with connecting plates 3, and the opposite sides of the two connecting plates 3 are hinged together, a plurality of plugs 4 are vertically fixedly connected to the top of the support plates 1, and a U-shaped support frame 5 is movably inserted between the two opposite plugs 4 at the top of the two support plates 1, and the outer surface of the support frame 5 is provided with a storage groove, and a pull rope 6 is arranged in the storage groove, and one end of the pull rope 6 is connected to the support One end of the frame 5 is fixedly connected near the bottom, and the other end of the pull rope 6 is fixedly connected to a movable block 7, which is slidably installed in the storage groove, and a plug hole 8 is penetrated through the top of the movable block 7, and a clamping assembly 9 is arranged between the plurality of movable blocks 7, and a limit rod 10 is arranged at one end of the pull rope 6 away from the movable block 7, and the two ends of the limit rod 10 are respectively fixedly connected to the front and rear inner walls of the storage groove, and the pull rope 6 is limited in the storage groove by the limit rod 10, and the width of the movable door 2 is the same as the width of the connecting plate 3, and the sum of the widths of the movable door 2 and the connecting plate 3 is less than the length of the support plate 1;

[0034] The clamping assembly 9 includes a connecting rod 91, and a slot 92 is provided at a position of the connecting rod 91 relative to the plurality of support frames 5, and the slot 92 is slidably connected with the corresponding support frame 5, an L-shaped connecting block 11 is fixedly connected in the slot 92, and the connecting block 11 is slidably plugged into the socket 8 of the corresponding movable block 7, a rotating shaft 94 is horizontally provided on the side of the connecting rod 91 away from the support frame 5, and both ends of the rotating shaft 94 are rotatably connected with the side of the connecting rod 91 away from the slot 92, and a plurality of spring clips 95 are fixedly connected to the connecting rod 91;

[0035] When building the dustproof shed, the two support plates 1 are pulled away from each other until the two connecting plates 3 are straightened and form an angle of ninety degrees with the support plates 1, and then the multiple support frames 5 are inserted in sequence between the two opposite insertion tubes 4 of the two support plates 1. When the multiple support frames 5 are assembled to the top of the two support plates 1, the distance between the two support plates 1 is also limited by the multiple support frames 5, and the main body of the entire dustproof shed is also built. Then, the plastic film used to shield dust and wind is covered on the support frame 5. However, since the height of the support frame 5 is relatively high, it is difficult to cover the plastic film. At this time, by providing a clamping assembly 9, the clamping assembly 9 can be used to assist in covering the plastic film, and the specific covering method is as follows:

[0036] First, the connecting blocks 11 in the multiple card slots 92 on the connecting rod 91 are plugged together with the connecting blocks 11 in the corresponding support frame 5, and then one side of the plastic film is opposite to the connecting rod 91, and then the multiple spring clips 95 on the rotating shaft 94 are used to clamp the middle of the edge of the plastic film on the side opposite to the connecting rod 91. When the plastic film is clamped, pull the pull rope 6 close to one end of the limit rod 10. As the pull rope 6 is pulled, the connecting rod 91 can pull the plastic film to move slowly along the outer surface of the support frame 5 under the drive of the pull rope 6, and When pulling the pull rope 6, since there are multiple pull ropes 6, in order to ensure the stability of the overall movement of the connecting rod 91, the pull rope 6 in the middle can be pulled first. After the pull rope 6 in the middle moves a certain distance, the remaining pull ropes 6 are pulled, and multiple pull ropes 6 are pulled alternately in the above manner during the whole process, so as to ensure that the connecting rod 91 can smoothly drive the plastic film to cover the frame formed by the multiple support frames 5. When the connecting rod 91 moves along the storage groove of the support frame 5 to a position relative to the limit rod 10, the connecting rod 91 is originally The upward side becomes the downward side, and then the connecting rod 91 is pushed downward. At this time, the connecting block 11 on the connecting rod 91 can be smoothly separated from the corresponding movable block 7, and then the connecting rod 91 is pulled downward to drive the plastic film to continue to move. In this process, multiple spring clips 95 can be adaptively deflected with the rotating shaft 94 as the center of the circle, so that the tension generated by the spring clips 95 on the plastic film is always consistent with the movement direction of the plastic film. When the connecting rod 91 contacts the ground, the entire plastic film has been roughly covered on the support frame 5, and the side of the plastic film connected to the connecting rod 91 can be attached to the ground under the tension of the connecting rod 91. Then, the plastic film is arranged so that its front, back, left and right sides can keep in contact with the ground. Finally, a heavy object is used to press the plastic film except the ground positions on both sides opposite to the movable door 2 and the connecting rod 91, so as to fix the plastic film. At this point, the entire dustproof shed is built. When it is necessary to enter the dustproof shed, the side of the plastic film opposite to the movable door 2 can be lifted, and the inside of the dustproof shed can be entered through the movable door 2;

[0037] Compared with the existing operation of using PVC pipes to build a dustproof shed, the construction method of the present invention is simpler, more solid, and not easy to fall over. At the same time, since the support plate 1 and the support frame 5 in the present invention can be reused, the cost of subsequent construction of the dustproof shed is also saved;

[0038] When the dustproof shed is finished using, the plastic film is first removed from the support frame 5, and then the multiple support frames 5 are removed. After the support frames 5 are removed, the two support plates 1 are pushed to move toward each other, and at the same time, the two connecting plates 3 and the two movable doors 2 are deflected toward the middle of the two support plates 1, thereby realizing the folding operation of the support plates 1, the connecting plates 3 and the movable doors 2, reducing the occupied area of ​​the various components of the entire dustproof shed, thereby making it more convenient to store and transport the dustproof shed.

[0039] like Figures 1 to 5 As shown, both ends of the connecting rod 91 are fixedly connected with a fixing block 93, and the end of the fixing block 93 is hinged with a blocking rod 12, and a limiting block 13 is provided on the opposite side of the two blocking rods 12, and the two limiting blocks 13 are fixedly connected with the two connecting blocks 11 respectively, and the top and bottom of the limiting block 13 are provided with a clamping spring 14, and the clamping spring 14 is fixedly connected with the blocking rod 12, and the limiting block 13 is clamped by the two clamping springs 14, and a clamping plate 15 is provided on the opposite side of the two blocking rods 12, and the bottom edge of the clamping plate 15 is hinged with the blocking rod 12 through a torsion spring, and the top of the clamping plate 15 is higher than the top of the blocking rod 12, and the top edges of the two clamping plates 15 protrude away from each other;

[0040] When the plastic film is covered on the frame composed of multiple support frames 5, the front and rear sides of the plastic film are prone to stacking due to the lack of support and fixation on the front and rear sides of the plastic film, thereby affecting the smooth covering of the plastic film. At this time, a baffle rod 12 is provided. When the middle part of the plastic film is clamped by the multiple spring clips 95 on the connecting rod 91, the two baffle rods 12 can be moved in turn to deflect the two baffle rods 12 in the direction close to each other. As the baffle rod 12 gradually deflects, when the baffle rod 12 deflects ninety degrees, the baffle rod 12 can fit together with the limit block 13, and the baffle rod 12 can be restricted by the two clamping springs 14 and connected. The rod 91 maintains an angle of ninety degrees, and then the plastic film is clamped together with the baffle rods 12 near the front and rear ends by using the clamping plates 15 on the two baffle rods 12. At this time, the top view of the entire plastic film is U-shaped under the support of the connecting rod 91 and the baffle rod 12. Then, when the connecting rod 91 is pulled along the outer surface of the support frame 5 by the pull rope 6, the entire plastic film can be slowly covered on multiple support frames 5. The presence of the baffle rod 12 also prevents the front and rear ends of the plastic film from being stacked and blocked due to lack of support during the process of covering the support frame 5, thereby ensuring that the plastic film can be covered on the entire support frame 5 more smoothly.

[0041] like Figure 1 , Figure 2 and Fig. 9As shown, two crosspieces 16 are arranged between two adjacent support frames 5, and the two crosspieces 16 are respectively located at the positions of the vertical sections on both sides of the support frame 5, and the bottom of the crosspiece 16 near the two ends is vertically fixedly connected with a plug rod 27, and a connecting sleeve 17 is slidably sleeved on the plug rod 27, and the connecting sleeve 17 is fixedly connected to the opposite support frame 5, and the inner side of the support frame 5 is fixedly connected with a grounding wire 18 at a position opposite to the crosspiece 16, and the top of the crosspiece 16 is fixedly connected with a terminal 19 near the grounding wire 18, and the terminal 19 can be connected to the grounding wire 18;

[0042] By providing the crossbar 16, the stability between the multiple support frames 5 can be improved, and by providing the grounding wire 18, when the entire dustproof shed is assembled, the grounding wire 18 can be connected to the terminal 19 on the crossbar 16, thereby meeting the grounding requirements when installing live equipment.

[0043] like Figure 1 and Figure 2 As shown, the first roller 20 is installed near the front and rear sides of the bottom of the support plate 1, and the first roller 20 has a self-locking function. The second roller 21 is installed at the opposite positions of the bottom of the two movable doors 2. The second roller 21 and the first roller 20 are universal wheels, and the bottoms of the first roller 20 and the second roller 21 are flush with each other;

[0044] By providing the first roller 20, the assembled support plate 1 and the support frame 5 can be conveniently moved as a whole, thereby satisfying the adjustment of the position of the dustproof shed. After the position of the dustproof shed is adjusted, the self-locking function of the first roller 20 can be used to lock the position of the dustproof shed, thereby preventing the dustproof shed from moving randomly due to external force.

[0045] By providing the second roller 21, the bottom of the free end of the movable door 2 can be supported, so that the movable door 2 is more stable and convenient when opened and closed, and the stability of the support of the entire dustproof shed is improved in cooperation with the plurality of first rollers 20.

[0046] like Figure 1 and Figure 2 As shown, a plurality of panels 22 are arranged between the tops of the two support plates 1, and blocks 23 are fixedly connected to both sides of the panels 22. A bayonet 24 is provided at a position of the top of the support plate 1 opposite to the block 23, and the block 23 is clamped in the corresponding bayonet 24;

[0047] After the support plate 1, the connecting plate 3 and the movable door 2 are built, multiple panels 22 are laid on the top of the two support plates 1 in sequence, and connected together with the card blocks 23 on the panels 22 and the card slots 24 on the top of the support plates 1 to form a table top. At this time, the table top composed of multiple panels 22 can be used as an equipment conductor cleaning platform, and when the main transformer accessories are installed, it can be used as a tool placement platform to facilitate the collection of tools and machinery, and facilitate on-site tool management and scene mode layout.

[0048] like Figure 6 and Figure 7 As shown, a notch 25 is provided on one side of the support frame 5 away from the connecting rod 91 along the front-to-back direction, and the notch 25 is connected to the storage slot, the notch 25 is close to the top of the panel 22, and a pull rod 26 is inserted through the notches 25 of the plurality of support frames 5;

[0049] By providing the pull rod 26, when one person operates, the pull rod 26 can be inserted into the notches 25 of the plurality of support frames 5, and the pull rope 6 on the support frame 5 can be moved as shown in FIG. Figure 7 As shown, the pull rod 26 is located on the pull rod 26, and then the pull rod 26 is pulled to move away from the support frame 5. As the pull rod 26 moves, the multiple pull ropes 6 can synchronously pull the corresponding movable blocks 7 under the stimulation of the pull rod 26, so that a single person can also control the multiple pull ropes 6 well, improving the convenience of plastic film covering;

[0050] After the use of the pull rod 26 is completed, the pull rod 26 can be pressed to the position where the plastic film contacts the ground, thereby improving the stability of the plastic film after covering.

[0051] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
