Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a new type of louvered low wind resistance prefabricated fence. Background Technology

[0002] During municipal road construction, barriers are used to isolate the construction area. This isolation protects the safety of construction workers and pedestrians and prevents sand and gravel particles from splashing and injuring passersby. Common barriers use panels for isolation, but in windy weather, this increases wind resistance and may lead to the barriers being blown down and injuring pedestrians and affecting traffic.

[0003] For example, a foldable and unfoldable barrier fencing building system with announcement number CN120211550A. The foldable and unfoldable barrier fencing building system provided by the present invention has the advantages of being easy to fold and easy to install, and solves the problem that the existing barrier fencing is inconvenient to fold and transport during use, but the overall fence surface is relatively closed and the wind resistance is large.

[0004] Furthermore, in the mobile, low-wind-resistance, foldable fencing with announcement number CN221502953U, this solution uses a dense mesh transparent fencing instead of a baffle-type fencing. Although this solves the wind resistance problem, it does not effectively solve the problem of sand and gravel splashing.

[0005] Both of the above solutions only address one aspect of the problem and still have significant drawbacks.

[0006] Therefore, the applicant provides a technical solution that can effectively address the aforementioned issues in a unified manner. Summary of the Invention

[0007] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a new type of louvered low wind resistance assembled fence. It can control the rotation of the louvers through a worm gear to adjust the gap between the louvers and control the wind resistance. It can not only prevent sand and gravel from flying and injuring passers-by, but also reduce wind resistance and stabilize the fence.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A novel louvered, low-wind-resistance prefabricated enclosure includes a base, a fixed frame, a mounting frame, and louvered panels. The fixed frame has a fixed plate at its bottom end, which is bolted to the base. The mounting frame is fixedly connected to the fixed frame. The mounting frame includes a square tube and side frames that are fixedly connected to each other. The side frames include a frame and a sealing plate that are fixedly connected to each other. Several louvered panels are provided, with rotating shafts at both ends, which rotatably connect to the frame. A worm gear is provided on one end of the rotating shaft of each louvered panel. A worm is provided inside the frame, with both ends rotatably connected to the top wall of the frame. The worm meshes with the worm wheel. By rotating the worm, the gap between adjacent louvered panels can be controlled and adjusted, changing the wind resistance. Fixed shafts are bolted to both ends of the worm, which rotatably connect to the frame. The use of fixed shafts facilitates the installation of the worm.

[0010] A limiting plate is provided on one side of the frame of the mounting frame. The limiting plate is inserted into the frame and has a slot. The slot engages the worm gear to prevent it from swinging due to its long length, which would affect the rotation operation. A retaining plate is provided at the end of the limiting plate. The retaining plate is located on the outside of the frame and is fixed to the frame by bolts. The limiting plates are fixed on both sides of the frame, and their cooperation ensures that the worm gear is subjected to uniform and stable force.

[0011] A bevel gear is provided on the fixed shaft at one end of the worm, and a control shaft is provided on the frame for rotational connection. The control shaft is provided with a bevel gear that meshes with the bevel gear on the fixed shaft. By rotating the control shaft, the worm can be controlled to rotate, which can be done quickly and with less effort.

[0012] Furthermore, the control shaft is equipped with a plug-in dial that provides convenience and labor-saving when rotating the control shaft.

[0013] Furthermore, the sealing plate is provided with a fixing block, and the fixing block is provided with a threaded hole; when the sealing plate is fixed, the fixing block is inserted into the frame and fits against the inner wall of the frame, and then the fixing block is locked by bolts to complete the fixing of the sealing plate.

[0014] Furthermore, the base is provided with a through groove, which facilitates the bolt fixing connection between the fixing frame and the base.

[0015] The louvers have wedge-shaped surfaces at both ends. When the louvers are rotated by rotating the worm gear, the wedge-shaped surfaces between adjacent louvers can fit together to achieve maximum closure.

[0016] The base has a cavity that can be filled with counterweights to stabilize the enclosure.

[0017] The advantages of this utility model compared with the prior art are as follows:

[0018] In this solution, the rotation of the shaft can be controlled by the rotation of the worm gear; in turn, the rotation of the louvers can be controlled, thereby controlling the gap between adjacent louvers, thus increasing the gap to cope with excessive wind speed and reduce wind resistance to stabilize the enclosure; the use of louvers can avoid the disadvantage of sand and gravel particles being easily splashed and injuring passers-by when using transparent enclosures with dense mesh netting. At the same time, the rotation adjustment of the louvers divides the integral baffle into several controllable baffles, solving the problem of the enclosure being unstable due to high wind resistance;

[0019] Furthermore, the gap between adjacent louvers is an angled channel. Even if sand or gravel enters the channel, it will be blocked and its direction of movement will be changed, causing it to fall downwards at an angle. This avoids the drawback of sand or gravel flying through and injuring pedestrians when using horizontal channels or transparent mesh barriers.

[0020] Secondly, the louvered panel end face is also provided with a wedge-shaped surface. When constructing in windless weather, the rotation of the louvered panel can be controlled to make the wedge-shaped surfaces between adjacent louvered panels fit together, maximizing the enclosure and greatly avoiding the impact of sand and gravel splashing.

[0036] To facilitate understanding by those skilled in the art, the following is a detailed explanation in conjunction with the appendix. Figure 1-10 The technical solution of this utility model will be further described in detail below.

[0037] A novel louvered, low-wind-resistance prefabricated enclosure includes a base 1, a fixed frame 2, a mounting frame 3, and louvered panels 4. The fixed frame 2 has a fixed plate 21 at its bottom end, which is connected to the base 1 by bolts. The mounting frame 3 is fixedly connected to the fixed frame 2. The mounting frame 3 includes a square tube 31 and a side frame 32 fixedly connected to each other. The side frame 32 includes a frame 321 and a sealing plate 322 fixedly connected to each other. Several louvered panels 4 are provided, and each louvered panel 4 has a rotating shaft 41 at both ends, the rotating shaft 41 rotatably connecting the frame. The frame 321 has a worm gear 42 mounted on a shaft 41 at one end of the louvered plate 4. A worm 5 is installed inside the frame 321, with both ends of the worm 5 rotatably connected to the top wall of the frame 321. The worm 5 meshes with the worm gear 42. By rotating the worm 5, the worm gear 42 and the louvered plate 4 are rotated, controlling and adjusting the gap between adjacent louvered plates 4 to change the wind resistance. Fixed shafts 51, which are bolted to both ends of the worm 5, are rotatably connected to the frame 321. The use of fixed shafts 51 facilitates the installation of the worm 5.

[0038] A limiting plate 6 is provided on one side of the frame 321 of the mounting frame 3. The limiting plate 6 is inserted into the frame 321 and has a slot 61. The slot 61 engages the worm gear 5 to prevent swaying due to the long length of the worm gear 5, which would affect the rotation operation. A retaining plate 62 is provided at the end of the limiting plate 6. The retaining plate 62 is located on the outside of the frame 321. The retaining plate 6 is fixed to the frame 321 by bolts. The limiting plates 6 are fixed on both sides of the frame 321, and their cooperation ensures that the worm gear 5 is subjected to uniform and stable force. As shown in the attached figure. Figure 5 As shown.

[0039] A bevel gear is provided on the fixed shaft 51 at one end of the worm gear 5, and a control shaft 7 is provided on the frame 321 for rotatable connection. The control shaft 7 is provided with a bevel gear that meshes with the bevel gear on the fixed shaft 51. By rotating the control shaft 7, the worm gear 5 is controlled to rotate, which can be done quickly and with less effort; as shown in the attached figure. Figure 5 As shown.

[0040] Furthermore, the control shaft 7 is provided with a plug-in dial 71, which can provide convenience and save effort in rotating the control shaft 7.

[0041] Furthermore, the sealing plate 322 is provided with a fixing block 3221, and the fixing block 3221 is provided with a threaded hole; when the sealing plate 322 is fixed, the fixing block 3221 is inserted into the frame 321 and fits against the inner wall of the frame, and then the fixing block 3221 is locked by bolts to complete the fixing of the sealing plate 322.

[0042] Furthermore, the base 1 is provided with a through groove 11, which facilitates the bolted connection between the fixing frame 2 and the base 1.

[0043] The louvers 4 are provided with wedge-shaped surfaces 43 at both ends. When the louvers 4 are rotated by rotating the worm gear 5, the wedge-shaped surfaces 43 between adjacent louvers 4 can fit together to achieve maximum closure. The open state of the louvers 4 is shown in the attached figure. Figure 7 As shown in the attached diagram, the closed state is as follows. Figure 8 As shown.

[0044] The base 1 has a cavity 12 that can be filled with counterweights to stabilize the enclosure.

[0045] This fencing can be folded up and stored during transportation, saving space and making it easy to store, as shown in the attached document. Figure 10 As shown; when in use, simply fix the fixed frame 2 and the base 1 together with bolts. When the wind speed is high, the wind resistance will increase and the fence will become unstable. Adjust the louver 4 by using the worm gear 5 to increase the gap between adjacent louver 4, increase the air volume, reduce the wind resistance, and stabilize the fence. When there is no wind, rotate the louver 4 and close the mounting frame 3 to protect the safety of pedestrians.
