Description

Technical Field

[0001] This utility model relates to the field of soundproof room technology, and more specifically, to a modular fan soundproof room. Background Technology

[0002] In the glass tempering furnace production process, it is necessary to cool the molten glass. This is typically achieved using a cooling fan system that provides forced airflow to rapidly cool the heated glass to obtain the required strength and safety. Inevitably, the operation of these fans usually generates 85-110 decibels of industrial noise. This not only fails to meet national noise emission standards but also causes significant sound pollution, affecting worker efficiency and negatively impacting their physical and mental health.

[0003] Therefore, in existing technology, the fan is generally installed inside a soundproof room to effectively isolate the noise generated when the fan is working. However, the top of the soundproof room is usually equipped with an air intake grille. The purpose of the air intake grille is to allow outside air to enter the soundproof room and dissipate heat. However, the air intake grille is usually open even when the fan is not running. Over time, outside dust can easily enter the soundproof room through the air intake grille, thus affecting the working environment inside the soundproof room. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a modular soundproof room for fans.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A modular soundproof enclosure for a fan is provided, comprising a base plate, soundproof side plates, and a soundproof top plate. One of the soundproof side plates has a soundproof door. When in use, the fan is located inside the soundproof enclosure. The soundproof top plate has a through hole, and several baffles are spaced apart in the through hole. When the fan is working, the baffles can be opened to allow outdoor air to enter the soundproof enclosure; when the fan is not working, the baffles can close the through hole.

[0007] Furthermore, in this utility model, a plurality of rotating shafts are arranged parallel to each other on the soundproof side plate, and any one of the rotating shafts is rotatably connected to the soundproof side plate; a plurality of baffles are arranged one-to-one on the plurality of rotating shafts; a linkage mechanism is provided on the soundproof side plate, and any one of the rotating shafts is drivenly connected to the linkage mechanism. The linkage mechanism can make the plurality of rotating shafts rotate synchronously, so that the plurality of baffles rotate synchronously, and a gap exists between two adjacent baffles.

[0008] Furthermore, in this utility model, the linkage mechanism includes a rack slidably disposed on the sound insulation side plate, the sliding direction of the rack being perpendicular to the central axis of any of the rotating shafts; a gear is fixedly disposed at the same end of each of the rotating shafts, and any of the gears meshes with the rack.

[0009] Furthermore, in this utility model, an elastic pad is provided at one end of any of the above-mentioned baffles near the other baffle. When both of the adjacent baffles are in a horizontal state, the elastic pad abuts against the end of the other baffle.

[0010] Furthermore, in this utility model, the linkage mechanism includes a drive shaft slidably disposed on the sound insulation side plate, the sliding direction of the drive shaft being perpendicular to the central axis of any of the rotating shafts; a cam is fixedly disposed at the same end of each of the rotating shafts, and a plurality of levers are spaced apart on the drive shaft, with each lever corresponding to one of the cams; when the drive shaft moves, the corresponding lever can cause the corresponding cam to rotate around the central axis of the corresponding rotating shaft.

[0011] Furthermore, in this invention, when the corresponding lever is not in contact with the corresponding cam, the cam keeps the corresponding baffle in a horizontal state.

[0012] The beneficial effects of this utility model are:

[0013] This utility model provides a modular fan soundproof room, in which several baffles form an air inlet grille. When the fan is working, the baffles can be tilted, and there is a gap between two adjacent baffles to facilitate the exchange of air between the soundproof room and the outside, which is beneficial to the heat dissipation of the soundproof room. When the fan is not working, the baffles can block the through holes to prevent external dust from entering the soundproof room. Attached Figure Description

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Example 1

[0022] Please see Figures 1-3 This embodiment provides a technical solution:

[0023] A modular soundproof enclosure for a fan is provided, comprising a base plate 101, soundproof side panels 201, and a soundproof top plate 301. Multiple soundproof side panels 201 or top plates 301 can be used depending on the specific requirements. Adjacent soundproof side panels 201 or top plates 301 can be connected by angle steel for easy assembly and disassembly. For easy worker access, a doorway is provided on one of the soundproof side panels 201, housing a soundproof door 401. During operation, the fan is located inside the soundproof enclosure. The soundproof top plate 301 has through holes, within which several baffles 501 are installed at intervals, forming an air intake grille. When the fan is operating, the baffles 501 can be opened to allow outdoor air to enter the soundproof enclosure; when the fan is not operating, the baffles 501 can close the through holes.

[0024] To facilitate the installation of several baffles 501, in this embodiment, several rotating shafts 601 are arranged parallel to each other on the soundproof side plate 201 (the central axes of each rotating shaft 601 are parallel to each other). Any rotating shaft 601 is rotatably connected to the soundproof side plate 201; several baffles 501 are fixedly installed on each rotating shaft 601 in a one-to-one correspondence. A linkage mechanism is provided on the soundproof side plate 201. Any rotating shaft 601 is drivenly connected to the linkage mechanism. The linkage mechanism can make several rotating shafts 601 rotate synchronously, so that several baffles 501 rotate synchronously, thus creating a gap between two adjacent baffles 501.

[0025] Specifically, refer to Figure 2 and Figure 3In this embodiment, the linkage mechanism includes a rack 701 slidably mounted on the soundproof side plate 201, the sliding direction of the rack 701 being perpendicular to the central axis of any rotating shaft 601; gears 702 are fixedly mounted on the same end of several rotating shafts 601, and any gear 702 meshes with the rack 701. A hydraulic rod can be connected to one end of the rack 701, the extension and retraction direction of the hydraulic rod being parallel to the length direction of the rack 701, to control the reciprocating movement of the rack 701.

[0026] Reference Figure 2 When the fan is not operating, the linkage mechanism keeps each baffle 501 in a horizontal position to block the through hole. When the fan is operating, each baffle 501 is in a horizontal position. Figure 3 The oblique state of the baffle 501. If the ends of each baffle 501 abut against each other when each baffle 501 is in a horizontal state, the rotation of the current baffle 501 will interfere with the rotation of the adjacent baffle 501. To solve this problem, the dimensions of the baffle 501 must satisfy the following: when each baffle 501 is in a horizontal state, there is a certain distance between two adjacent baffles 501. In this way, when each baffle 501 rotates synchronously under the control of the linkage mechanism, it will not interfere with each other and can rotate normally.

[0027] However, when the fan is not working, each baffle 501 is in a horizontal position. If there is a certain gap between two adjacent baffles 501, external dust can enter the soundproof room through this gap. To solve this problem, an elastic pad 801 is installed at the end of any baffle 501 closest to another baffle 501. The thickness of the elastic pad 801 is required to ensure that when both adjacent baffles 501 are in a horizontal position, the elastic pad 801 abuts against the end of the other baffle 501. In this way, when the fan is not working, several baffles 501 can completely seal the through hole, preventing external dust from entering the soundproof room.

[0028] Working principle:

[0029] from Figure 2 From the perspective of the fan, when the fan is working, the rack 701 can move left or right, and each gear 702 thus rotates synchronously under the action of the rack 701. The rotation of the gears 702 drives the synchronous rotation of each shaft 601, so that each baffle 501 is in position. Figure 3 The baffles 501 are tilted, with a gap between adjacent baffles 501 to facilitate heat dissipation in the soundproof room. When the fan is not working, the linkage mechanism brings each baffle 501 into a horizontal position to block the through holes.

[0030] Example 2

[0031] Please see Figure 4 and Figure 5The difference between this embodiment and Embodiment 1 is that the linkage mechanism in this embodiment includes a drive shaft 901 slidably mounted on the sound insulation side plate 201, the sliding direction of the drive shaft 901 being perpendicular to the central axis of any rotating shaft 601; cams 902 are fixedly mounted on the same end of several rotating shafts 601, and several levers 903 are spaced apart on the drive shaft 901, with each lever 903 corresponding to one of the cams 902; when the drive shaft 901 moves, the corresponding lever 903 can cause the corresponding cam 902 to rotate around the central axis of the corresponding rotating shaft 601. Similarly, a hydraulic rod can be connected to one end of the drive shaft 901, the extension and retraction direction of the hydraulic rod being parallel to the central axis of the drive shaft 901, to control the reciprocating movement of the drive shaft 901.

[0032] Meanwhile, cam 902 also acts as a counterweight here. When lever 903 is not in contact with the corresponding cam 902, baffle 501 is in a horizontal state under the gravity of cam 902. Specifically, in this embodiment, the middle part of baffle 501 is connected to shaft 601. After cam 902 is installed on shaft 601, its rotation center line is collinear with the central axis of shaft 601. Therefore, under natural conditions, the gravity of cam 902 can keep baffle 501 in a horizontal state.

[0033] The above structure can also allow several baffles 501 to be in a horizontal or inclined state.

[0034] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
