Description

Technical Field

[0001] The present invention relates to the technical field of silencers, and in particular to a silencer module protective cover and an installation and removal method of an array silencer used in underground air ducts or air shafts of rail transit, etc. Background Art

[0002] Array silencer is a silencing device widely used for fan silencing in underground air ducts or air shafts in rail transit projects. It consists of a metal frame and a silencing module. The finished silencing module arrives on site and is installed in an array in the metal frame.

[0003] Usually, the installation site is dusty, there is sewage sometimes, and the underground space is humid. At the same time, the surface of the silencer module is a steel perforated plate, and the interior is a porous fiber sound-absorbing material, which is very easy to accumulate dust and absorb moisture. If the sound-absorbing material is blocked by dust or damp, the noise reduction effect of the silencer will be greatly reduced.

[0004] At present, the silencer modules shipped to the site by the manufacturer are basically not protected. If the purchaser makes a protection request, the manufacturer will only provide simple protection by wrapping a plastic film. If the protective film is removed before installation, there will be at least three months from the completion of the installation to the operation (taking the rail transit project as an example). During this period, other equipment in the air duct needs to be debugged and the air duct needs to be cleaned, so the silencer will still be contaminated by dust and water; if it is removed after installation, due to the large size and high height of the array silencer, and the small space between modules, the protective film will be extremely difficult to remove. Summary of the invention

[0005] In view of the problem that the existing array silencers have no protective cover or have a protective film that is extremely difficult to remove, the present invention aims to provide an easily removable protective cover for a silencer module, which can prevent the influence of dust, sewage and moisture on the silencer module at the construction site, and solve the problem that the protective film is difficult to remove.

[0006] To this end, the technical solution adopted by the present invention is: a protective cover that is easily removable for a silencer module, comprising a protective cover body that matches the outer contour of the silencer module, the protective cover body having a self-sealing adhesive for quick sealing after the silencer module is inserted, an easy-tear strip with a reserved easy-tear seam is arranged at the front and rear center position of the protective cover body, a reserved finger buckle is arranged at the upper end or the lower end of each vertical segment of the easy-tear strip, and a removal component is arranged outside each horizontal segment of the easy-tear strip, the removal component comprises a removal driving piece, a pull rope, a fixing nail and a pull ring, the removal driving piece is composed of an upper and lower clamping piece, and one end of the horizontal segment and one end of the pull rope are clamped in the middle and fixed firmly, the fixing nail is installed at the other end of the horizontal segment to fix the other end of the pull rope, and the pull rope passes through the fixing nail and is tied with a pull ring on the end.

[0007] The above-mentioned silencing module easily removable protective cover is also equipped with a protective cover removal hook, which includes a retractable rod and a hook head. The hook head is a semicircular ring, one end of the semicircular ring is connected to the rod, and the other end is provided with a barb facing the rod and parallel to the rod.

[0008] The present invention also provides an array-type silencer, comprising a metal frame and a silencer module, wherein the silencer module is installed in an array in the metal frame by means of mounting bolts on the left and right sides, and each silencer module is sheathed with the above-mentioned silencer module easily detachable protective cover, and the mounting bolts correspond to the vertical section position of the easily tearable strip.

[0009] The present invention also provides a method for installing and removing the protective cover of the above array type muffler, comprising the following steps:

[0010] Step 1: Before leaving the factory, put the easily removable protective cover on the outer surface of the silencer module and quickly seal it with the self-contained sealing adhesive;

[0011] Step 2: transport the silencer module to the installation site. Before installing the silencer module, tear off the vertical section of the easy-tear strip through the reserved finger buckles on the two vertical sections of the easy-tear protective cover to expose the installation bolt holes, and install the silencer modules with the easy-tear protective cover into the metal frame one by one with the installation bolts;

[0012] Step three, after the installation site is cleaned and the array silencer is officially put into use, the easily removable protective covers will be removed one by one; first, use your hands or the protective cover removal hook to pull the upper and lower pull rings of the easily removable protective cover respectively, and the pull rope will pull the removal driving piece to tear the easy-tear seam strip to split the easily removable protective cover into two; then, use your hands or the protective cover removal hook to pull the easily removable protective cover out through the front and rear spaces to complete the removal.

[0013] The beneficial effects of the present invention are as follows: the easily removable protective cover can protect the silencer module in the array silencer from the influence of dust, sewage and moisture at the construction site; it matches the outer contour of the silencer module and has its own sealing sticker, so it is convenient and quick to put on and is beautiful and neat; after the silencer module is installed, the protective cover is easy to remove, which effectively solves the problem that the current silencer is affected by the construction environment and the protective film is difficult to remove.

[0020] The present invention will be further described below by way of embodiments and in conjunction with the accompanying drawings:

[0021] Combination Figure 1 — Figure 4 As shown, an easily removable protective cover for a silencer module is composed of a protective cover body 1 and two sets of removal components.

[0022] The protective cover body 1 matches the outer contour of the muffler module, and can be made of soft and tough protective plastic cloth or plastic film. The protective cover body 1 has a sealing adhesive 2 for quick sealing after the muffler module is inserted. An easy-tear strip 3 with a reserved easy-tear seam is provided at the front and rear center of the protective cover body 1. The easy-tear strip 3 is divided into two vertical sections and two horizontal sections.

[0023] A reserved finger buckle 4 is provided at the upper end of each vertical segment of the easy-tear strip 3, and of course, a reserved finger buckle 4 can also be provided at the lower end of each vertical segment of the easy-tear strip 3. To provide the pre-splitting finger buckle 4, it is only necessary to uncover a section of the vertical segment to expose the mounting bolt hole on the muffler module for installation. Since there is still some time between the installation of the muffler and the formal start-up, this structure can ensure normal installation without removing the entire protective cover.

[0024] A dismantling assembly is arranged outside each horizontal section of the easy-tear strip 3, and the dismantling assembly is composed of a dismantling driving piece 12, a drawstring 5, a fixing nail 6 and a pull ring 7. The dismantling driving piece 12 is composed of two upper and lower clamping pieces, and the clamping piece is made of rubber or plastic sheets. The two clamping pieces clamp one end of the horizontal section and one end of the drawstring 5 in the middle and fix them firmly. The fixing nail 6 is installed at the other end of the horizontal section to fix the other end of the drawstring 5. The drawstring 5 passes through the fixing nail 6 and is tied with a pull ring 7 on the end. The fixing nail 6 is used to fix the end of the drawstring 5 to prevent the drawstring 5 from being fixed on the silencer module, so as to facilitate the quick finding of the pull ring 7 during dismantling. The drawstring 5 pulls the dismantling driving piece 12 to tear the easy-tear seam strip 3 and divide the easy-to-remove protective cover into two.

[0025] like Figure 5 As shown, the protective cover removal hook 8 is a removal tool provided, and the protective cover removal hook 8 is composed of a retractable rod 8a and a hook head 8b. The hook head 8b is a semicircular ring, one end of the semicircular ring is connected to the rod 8a, and the other end is provided with a barb 8c facing the rod 8a and parallel to the rod 8b.

[0026] like Figure 6 As shown, an array type silencer is mainly composed of a metal frame 9 and a plurality of silencer modules 10. The silencer modules 10 are installed in the metal frame 9 in an array type by means of mounting bolts 11 on the left and right sides. Each silencer module 10 is sheathed with the above-mentioned silencer module easily removable protective cover, and the mounting bolts 11 correspond to the vertical section position of the easy-tear strip 3.

[0027] A method for installing and removing a protective cover of an array type muffler comprises the following steps:

[0028] Step 1: Before leaving the factory, put the easily removable protective cover on the outer surface of the silencer module 10 and quickly seal it with the self-contained sealing adhesive 2.

[0029] Step 2: Transport the silencer module 10 to the installation site. Before installing the silencer module 10, tear off the vertical section of the easily-tearable strip 3 through the reserved finger buckles 4 on the two vertical sections of the easily-detachable protective cover to expose the installation bolt holes, and use the installation bolts 11 to install the silencer modules 10 with easily-detachable protective covers into the metal frame 9 one by one.

[0030] Step 3: After the installation site is cleaned and the array silencer is officially put into use, the easily removable protective covers are removed one by one; first, use your hands or the protective cover removal hook 8 to pull the upper and lower pull rings 7 of the easily removable protective cover respectively, and the pull rope 5 pulls the removal drive piece 12 to tear the easy-tear seam strip 3 to split the easily removable protective cover into two; then, use your hands or the protective cover removal hook 8 to pull the easily removable protective cover out through the front and rear spaces to complete the removal. For the silencer module at the bottom of the silencer, remove the protective cover directly by hand, and for the silencer module at the top of the silencer that cannot be touched by hand, use the matching retractable removal hook to remove the protective cover.
