Description

Technical Field

[0001] The utility model relates to the technical field of noise reduction of construction enclosures, in particular to a noise reduction type construction protection enclosure. Background Art

[0002] In cities, industrial and civil construction sites use a large number of power machines with different performances, which makes the originally quiet environment become a place with serious noise pollution. Some construction sites are close to residential buildings, which greatly disturbs the lives of residents. In particular, various knocks, collisions, the rotation of construction machinery and various noises generated during the work process have a certain impact on surrounding residents and construction workers. In the prior art, the fences used are limited in height, generally 2 meters, which can only block the sight of people outside, but cannot fully play the role of noise reduction.

[0003] After searching, the Chinese patent publication number CN218563248U discloses a construction site protection enclosure, including an enclosure frame, the inner surface of the enclosure frame is fixedly embedded with a sound insulation baffle, and the lower end outer surface of the enclosure frame is fixedly installed with a base. The construction site protection enclosure described in the utility model has a higher stability of the overall enclosure through the provided base, and has a certain anti-tilting function. When in use, the first anti-dumping vertical rod and the second anti-dumping vertical rod are located at the front and rear ends of the enclosure frame, which play a supporting and anti-dumping role for the enclosure frame. The construction site protection enclosure effectively improves the sound insulation function of the overall protection enclosure and effectively reduces construction noise through the provided sound insulation baffle. When in use, the setting of the card block and the sealing pad facilitates the installation between the overall sound insulation baffle and the enclosure frame. The first honeycomb mesh panel and the second honeycomb mesh panel have the same structure and both have good sound absorption and noise reduction functions.

[0004] The above patent has the following defects: the sound insulation baffle is a closed structure. When it is used on the fence, the fence will become closed. When the construction area is not in the construction state, the construction area enclosed by the fence does not need to be soundproofed or dustproof. On the contrary, some construction areas need to be ventilated. At this time, the closed fence will affect the ventilation state of the construction area, and it will not be possible to maintain the sound insulation effect while taking into account the ventilation function. This will increase the construction period and affect the construction progress. In view of this, we propose a noise reduction construction protection fence. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a noise-reducing construction protection fence, which solves the problems raised in the above background technology. To achieve the above purpose, the utility model is implemented through the following technical solutions: a noise-reducing construction protection fence, including a fence base, a retractable noise reduction device is arranged inside the fence base, a first railing and a second railing are respectively fixedly connected to the fence base, and the tops of the first railing and the second railing are both provided with fixing devices.

[0006] The retractable noise reduction device includes a winding roller, both ends of which are rotatably connected to the inside of the enclosure base, both end surfaces of the winding roller are fixedly connected to spiral springs, the surface of the winding roller is fixedly connected to a rainproof and sound-absorbing cotton cloth, the top of the rainproof and sound-absorbing cotton cloth is fixedly connected to a connecting seat, the connecting seat is fixedly connected to a connecting block on one side close to the first railing, and the interior of the connecting block is rotatably connected to an I-shaped sliding rod.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] See also Figure 1-Figure 4 As shown, a noise reduction type construction protection fence includes a fence base 1, a retractable noise reduction device 2 is arranged inside the fence base 1, a first railing 3 and a second railing 4 are respectively fixedly connected to the fence base 1, and a fixing device 5 is arranged at the top of the first railing 3 and the second railing 4.

[0024] In this embodiment, the retractable noise reduction device 2 includes a winding roller 21, both ends of which are rotatably connected to the inside of the enclosure base 1, and both end surfaces of the winding roller 21 are fixedly connected to spiral springs 22, the surface of the winding roller 21 is fixedly connected to a rainproof and sound-absorbing cotton cloth 23, the top of the rainproof and sound-absorbing cotton cloth 23 is fixedly connected to a connecting seat 24, the connecting seat 24 is fixedly connected to a side close to the first railing 3, and the interior of the connecting block 25 is rotatably connected to an I-shaped sliding rod 26. When the connecting seat 24 loses the positioning restriction, the connecting seat 24 as a whole is affected by the elastic winding of the winding roller 21 connected to the bottom end of the rainproof and sound-absorbing cotton cloth 23, and will slide downward in the convex groove 6 through the I-shaped slide bar 26. The winding roller 21 elastically winds up the rainproof and sound-absorbing cotton cloth 23, and the rolled-up rainproof and sound-absorbing cotton cloth 23 is stored inside the enclosure base 1. At this time, all the railings between the first railing 3 and the second railing 4 are exposed, and the enclosure base 1 as a whole is in an open enclosure effect, thereby achieving the effect of easy ventilation of the enclosure. By switching the rolled-up state and the covering state of the rainproof and sound-absorbing cotton cloth 23, the problem that traditional enclosures cannot take into account both sound insulation and ventilation effects is solved, so that the enclosure can switch functions according to actual construction conditions, thereby improving the overall practicality and applicability of the enclosure.

[0025] Furthermore, the end of the spiral spring 22 is fixedly connected to the inside of the enclosure base 1, and the surface of the rainproof and sound-absorbing cotton cloth 23 is slidably connected to the top of the enclosure base 1. The rainproof and sound-absorbing cotton cloth 23 is composed of a rainproof cloth and sound-absorbing cotton. The rainproof cloth is used to protect the sound-absorbing cotton and increase its service life. The sound-absorbing cotton is located inside the rainproof cloth, and a positioning groove 27 is opened inside the connecting seat 24.

[0026] Furthermore, the first railing 3 and the second railing 4 are both provided with a convex groove 6 , and the surface of the I-shaped sliding rod 26 is slidably connected to the inner wall of the convex groove 6 .

[0027] Example 2

[0028] See also Figure 1-Figure 4 As shown, the fixing device 5 includes a connecting frame 51, the surface of the connecting frame 51 is fixedly connected to the top of the first railing 3, the surface of the connecting frame 51 is elastically connected to a connecting plate 52 through a spring, the connecting plate 52 is rotatably connected to a clamping shaft 53, the top of the clamping shaft 53 is fixedly connected to a limiting plate 54, the bottom of the clamping shaft 53 is fixedly connected to a gear shaft 55, the surface of the gear shaft 55 is meshed with a rack 56, and the fixing device 5 is provided to insert and position the rainproof and sound-absorbing cotton cloth 23 covering the railing, thereby ensuring that the rainproof and sound-absorbing cotton cloth 23 stably covers the railing to reduce noise, and at the same time, by utilizing the simple processing properties of its internal structure, the effect of quickly positioning and disassembling the rainproof and sound-absorbing cotton cloth 23 can be achieved, and the operation is convenient.

[0029] It is worth noting that the surface of the card shaft 53 is movably connected to the inside of the connecting frame 51, the top of the card shaft 53 is connected to the inner wall of the positioning groove 27, and the surface of the rack 56 is slidably connected to the inside of the connecting plate 52. By rotating the card shaft 53 at any one of the first railing 3 or the second railing 4, the card shaft 53 in the other railing can achieve a synchronous rotation effect through the meshing effect of the rack 56 and the gear shaft 55, thereby improving the convenience of rotation of the card shaft 53.

[0030] In addition, a drainage groove 7 is provided at the bottom of the first railing 3 and the second railing 4, and the drainage groove 7 is used to discharge rainwater and impurities inside the first railing 3 and the second railing 4. A drainage groove 2 8 is provided at the bottom of the enclosure base 1, and the drainage groove 2 8 is used to discharge rainwater and impurities inside the enclosure base 1. A spring isolation plate 9 is fixedly connected to the inside of the enclosure base 1, and the spring isolation plate 9 is used to isolate and protect the spiral spring 22 to prevent rainwater and other impurities from contacting the spiral spring 22 and affecting its service life.

[0031] When the noise reduction type construction protection fence of the utility model is in use, the rainproof and sound-absorbing cotton cloth 23 is normally spread on the fence railing, which can soundproof and reduce noise in the fence area, thereby improving the overall noise reduction effect of the fence base 1. When the construction is completed and the fence area needs to be ventilated, the operator rotates the clamping shaft 53 at the first railing 3 or the second railing 4 so that the limit plate 54 on the clamping shaft 53 is parallel to the positioning groove 27. When the clamping shaft 53 is rotated, the rotational force of the clamping shaft 53 acts on the rack 56 through the gear shaft 55, and the rack 56 applies the moving force to the other gear shaft 55 again, thereby achieving the effect of rotating the clamping shaft 53 at any first railing 3 or the second railing 4, and the clamping shaft 53 in the other railing rotates synchronously. After rotation, the connecting plate 52 is directly pressed down as a whole, and the connecting plate 52 drives the two clamping shafts 53 to move away from the positioning grooves 27 at the first railing 3 and the second railing 4. When the clamping shaft 53 moves away from the positioning grooves 27 After the groove 27 is positioned, the connecting seat 24 loses the positioning restriction of the card shaft 53. At this time, the connecting seat 24 is affected by the elastic winding of the winding roller 21 connected to the bottom end of the rainproof and sound-absorbing cotton cloth 23, and slides downward in the convex groove 6 through the I-shaped slide bar 26. During the downward sliding period, the winding roller 21 elastically rolls up the rainproof and sound-absorbing cotton cloth 23. The rolled up rainproof and sound-absorbing cotton cloth 23 is stored inside the enclosure base 1, and the connecting seat 24 is located at the bottom of the railing. At this time, all the railings between the first railing 3 and the second railing 4 are exposed, and then the enclosure base 1 as a whole is in the effect of an open enclosure, so that it is convenient for the enclosure to ensure the ventilation effect of the construction area. By switching the rolled-up state and the covering state of the rainproof and sound-absorbing cotton cloth 23, the problem that the traditional enclosure cannot take into account both the sound insulation effect and the ventilation effect is solved, so that the enclosure can switch its function according to the actual construction situation, thereby improving the overall practicality and applicability of the enclosure.

Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the embodiments of the utility model. Therefore, all equivalent technical solutions also belong to the scope of the embodiments of the utility model. The patent protection scope of the embodiments of the utility model should be limited by the claims.
