Description

Technical Field

[0001] This utility model relates to the field of noise control device technology, specifically to a construction site noise control device. Background Technology

[0002] Noise refers to undesirable sounds that cause disturbance, discomfort, or potential harm to specific groups of people or the environment. In traditional construction sites, construction machinery generates noise when it is working. Noise control often relies on noise detection equipment to monitor the noise emitted on site. If the noise exceeds the limit decibel, human intervention is used to reduce the noise on site, which is often achieved by setting up barriers around the construction site.

[0003] Currently, the method of reducing noise at construction sites by using barriers is quite outdated. Although barriers can reduce the noise generated during construction to some extent, their noise reduction ability is weak and cannot be compared with dedicated noise reduction equipment. Noise pollution still exists, and when the noise level exceeds the limit decibel, it has already affected the surrounding area and impacted the company's civilized construction practices.

[0004] Based on this, the present invention designs a construction site noise control device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a construction site noise control device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a construction site noise control device, comprising a noise-reducing honeycomb panel, a winged iron plate, a first hinge, a vertical pole, mounting supports, and fixing pins. The noise-reducing honeycomb panel includes an iron plate body, a plastic plate, and a honeycomb structure. The upper end of the iron plate body is fixedly connected to the plastic plate, and the plastic plate is densely covered with honeycomb structures. A winged iron plate is provided at the center of the noise-reducing honeycomb panel, and a vertical pole is provided at the lower end of the winged iron plate. The vertical pole and the winged iron plate are movably connected through the first hinge. Four mounting supports are fixedly connected to the back of the noise-reducing honeycomb panel.

[0007] As a preferred technical solution of this utility model, a baffle is provided on the back of the top noise-reducing honeycomb plate of the winged iron plate, a clamping rod is fixedly connected to the lower end of the winged iron plate, a first pin hole is provided on the clamping rod, a pull rope is fixedly connected to the tail end of the clamping rod, and the other end of the pull rope passes through the upright.

[0008] As a preferred technical solution of this utility model, a slot is provided on the upright, and a second pin hole is provided at the slot.

[0009] As a preferred embodiment of this utility model, the clamping rod at the lower end of the winged iron plate is disposed in the clamping groove, and the first pin hole on the clamping rod is connected to the second pin hole on the upright.

[0010] As a preferred embodiment of this utility model, the fixing pin passes through the first pin hole and the second pin hole to connect and fix the clamp rod and the upright rod.

[0011] As a preferred embodiment of this utility model, the winged iron plate flange is disposed on the back of the noise-reducing honeycomb panel, and the winged iron plate flange is fixedly connected to the back of the noise-reducing honeycomb panel.

[0012] As a preferred embodiment of this utility model, the mounting support rod includes a connecting support rod, a second hinge, and a fixing rod. The connecting support rod is fixedly connected to the back of the noise-reducing honeycomb panel, and the connecting support rod is movably connected to the fixing rod through the second hinge.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. When in use, this utility model, through the honeycomb structure design of the noise-reducing honeycomb panel, can effectively increase the surface area of ​​the noise-reducing panel. When the noise from the construction site is transmitted to the noise-reducing honeycomb panel, the noise-reducing honeycomb panel converts part of the noise into its own vibration, reducing the noise level. It has a strong noise reduction capability and can significantly reduce the noise generated at the construction site, avoiding the impact on the surrounding environment. Moreover, the device is simple to operate, and only one person is needed to maintain and control the noise reduction device at the entire construction site, realizing the active control of noise at the construction site.

[0015] 2. When using this utility model, the winged iron plate is raised by pulling the rope, and the flange of the winged iron plate will drive the noise reduction honeycomb plate to rise. When the noise reduction honeycomb plate is raised to a vertical position, the locking rod is fixed in the slot by the fixing pin, and the noise reduction device enters the noise reduction working state. When the wind level at the scene is high, the fixing pin can be pulled out, and the noise reduction plate will automatically retract by gravity, which can realize the function of retracting and extending the noise reduction honeycomb plate and avoid damage caused by excessive wind pressure on the surface of the noise reduction plate.

[0025] The following will refer to the appendix in the embodiments of this utility model. Figure 1-7 The technical solutions in the embodiments of this utility model are clearly and completely described herein. 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.

[0026] Example

[0027] Please see Figure 1-7 This utility model provides the following technical solution: a construction site noise control device, including a noise-reducing honeycomb panel 1, a winged iron plate 2, a first hinge 3, a vertical pole 4, mounting supports 5, and a fixing pin 6. The noise-reducing honeycomb panel 1 includes an iron plate body 101, a plastic plate 102, and a honeycomb structure 103. The upper end of the iron plate body 101 is fixedly connected to the plastic plate 102, and the plastic plate 102 is densely covered with honeycomb structures 103. The winged iron plate 2 is provided at the center of the noise-reducing honeycomb panel 1, and the lower end of the winged iron plate 2 is provided with a vertical pole 4. The vertical pole 4 and the winged iron plate 2 are movably connected through the first hinge 3. Four mounting supports 5 are fixedly connected to the back of the noise-reducing honeycomb panel 1.

[0028] The densely packed honeycomb structures 103 on the plastic plate 102 can effectively increase the surface area of ​​the noise reduction plate. At the same time, when the noise from the construction site is transmitted to the noise reduction honeycomb plate 1, the noise reduction honeycomb plate 1 will convert part of the noise into its own vibration, which has a strong noise reduction capability.

[0029] A baffle 201 is provided on the back of the top noise reduction honeycomb panel 1 of the winged iron plate 2. A clamping rod 202 is fixedly connected to the lower end of the winged iron plate 2. A first pin hole 203 is provided on the clamping rod 202. A pull rope 204 is fixedly connected to the tail end of the clamping rod 202. The other end of the pull rope 204 passes through the upright 4.

[0030] The upright 4 has a slot 401, and a second pin hole 402 is provided at the slot 401.

[0031] The clamping rod 202 at the lower end of the winged iron plate 2 is set in the clamping groove 401, and the first pin hole 203 on the clamping rod 202 is connected to the second pin hole 402 on the upright rod 4.

[0032] The fixing pin 6 passes through the first pin hole 203 and the second pin hole 402 to connect and fix the clamping rod 202 and the upright rod 4.

[0033] The winged iron plate 2 has its flanges set on the back of the noise-reducing honeycomb panel 1, and the flanges of the winged iron plate 2 are fixedly connected to the back of the noise-reducing honeycomb panel 1.

[0034] Through the movable connection structure design of the winged iron plate 2, the first hinge 3 and the upright 4, by pulling the pull rope 204, the pull rope 204 pulls the locking rod 202 to make the winged iron plate 2 stand up. The wing edge of the winged iron plate 2 drives the noise reduction honeycomb plate 1 to stand up until the locking rod 202 is inserted into the locking slot 401. When the pull rope 204 can no longer be pulled, the noise reduction honeycomb plate 1 stands up to a vertical state, completing the unfolding of the noise reduction honeycomb plate 1 and putting the noise reduction honeycomb plate 1 into noise reduction working state.

[0035] The mounting rod 5 includes a connecting rod 501, a second hinge 502, and a fixing rod 503. The connecting rod 501 is fixedly connected to the back of the noise-reducing honeycomb panel 1, and the connecting rod 501 is movably connected to the fixing rod 503 through the second hinge 502.

[0036] After the fixing rod 503 is fixed to the enclosure, the connecting support rod 501 can rotate with the opening and closing of the noise reduction honeycomb panel 1 under the connection of the second hinge 502, which facilitates the support of the noise reduction honeycomb panel 1.

[0037] The working principle and usage process of this utility model are as follows: In specific use, the device is installed above the existing fence at the construction site using the upright 4 and the mounting support 5. By pulling the rope 204, the winged iron plate 2 is erected, and the flange of the winged iron plate 2 drives the noise reduction honeycomb plate 1 to be erected. When the noise reduction honeycomb plate 1 is erected to a vertical position, the locking rod 202 at the lower end of the winged iron plate 2 is inserted into the slot 401 on the upright 4. Then, the locking rod 202 is fixed in the slot 401 using the fixing pin 6, and the noise reduction device enters the noise reduction working state. When the noise from the construction site is transmitted to the noise reduction honeycomb plate 1, through the honeycomb noise reduction structure design on the surface of the noise reduction honeycomb plate 1, part of the noise is converted into its own vibration, reducing the noise decibels and reducing the impact of construction site noise on the surroundings. During use, when the wind level at the site is high, the fixing pin 6 can be pulled out, and the noise reduction plate will automatically retract by gravity, realizing the retraction and extension function of the noise reduction honeycomb plate 1 and avoiding damage caused by excessive wind pressure on the surface of the noise reduction plate.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
