Description

Technical Field

[0001] The utility model relates to the field of sound insulation, noise reduction, environmental protection and energy saving of industrial structures, in particular to a testing device for a novel sound insulation and noise reduction coating structure. Background Art

[0002] With the continuous development of industrialization, noise pollution from industrial structures has become an environmental quality issue that cannot be ignored. Noise pollution not only threatens the physical and mental health of employees but also affects production efficiency and product quality. Therefore, it is imperative to implement effective noise insulation and noise reduction solutions.

[0003] Industrial structure noise reduction is essentially a two-step process: noise reduction for equipment or for the factory building. If noise still persists, a sound barrier must be installed between the factory building and the affected area. Reducing equipment noise or installing a sound barrier presents significant limitations, making installation unavailable in most industrial sites. Soundproofing factories is typically done with soundproofing cotton, but it's made from asbestos, which is highly harmful to the human body. Its fine fibers are easily inhaled, most notably causing lung disease and calcification. Furthermore, its effects aren't immediate; they typically accumulate over a long period of ten to twenty years.

[0004] However, the inventors have provided a corresponding sound insulation structure to meet the noise reduction needs. At the same time, they need to provide a corresponding testing device that can be displayed to users in a non-professional laboratory, while also taking into account the issues of simple structure and ease of use. Utility Model Content

[0005] The utility model aims to solve the above technical problems and provide a testing device for a novel sound insulation and noise reduction coating structure with a simple structure and easy use.

[0006] In order to solve the above technical problems, the embodiment of the present utility model provides a testing device for a novel sound insulation and noise reduction coating structure, which includes:

[0007] Support frame;

[0009] A fixing rod arranged on the supporting plate is provided with a test ball mounting cantilever, which is provided with a test ball.

[0010] Furthermore, the bearing portion has a flat plate portion and a U-shaped enclosure portion arranged along an edge of the flat plate portion.

[0011] Furthermore, the supporting plate is provided with a flexible buffer pad.

[0012] Furthermore, the side wall of the guide insertion groove body is provided with an anti-interference pad.

[0013] Furthermore, the test ball mounting cantilever has a horizontal U-shaped fork, a fixed tail rod arranged on the horizontal U-shaped fork, and a test ball placing plate arranged at the front end of the horizontal U-shaped fork and capable of being opened and closed. The test ball arranged on the test ball placing plate is connected to the fixed tail rod by a rope.

[0014] Furthermore, the fixing rod is L-shaped, and a locking portion is provided at a position where the L-shaped fixing rod passes through the bearing portion.

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments.

[0033] The embodiment of the present utility model provides a test device for a novel sound insulation and noise reduction coating structure, see Figure 1-10 As shown, it includes: a support frame 1, a vertical mounting bracket 2, a supporting plate 3, a guide slot 4, a bearing portion 5, a fixing rod 8, and a test ball mounting cantilever 9. To facilitate movement, a moving wheel can be installed at the bottom of the support frame, and the moving wheel can be a universal wheel with a brake device.

[0034] See also Figure 1-7 The support frame 1 serves as the bottom support structure of the entire test device. The bottom adopts a U-shaped structure 1-1. Two vertical triangular structures 1-2 are relatively distributed on the U-shaped structure at the bottom, and the two triangular structures are connected by a crossbar 1-3. As an option, the support frame is made of metal material. The vertical mounting bracket 2 is arranged at the crossbar 1-3 of the support frame. The vertical mounting bracket 2 has two parallel vertical poles (or vertical plates). A horizontally distributed square support plate 3 is provided on the vertical mounting bracket. The square support plate can be used to install auxiliary structures while also strengthening the stability of the vertical mounting bracket. A bearing part 5 installed on the vertical mounting bracket is provided above the support plate. The bearing part can adopt a plate structure to facilitate the placement of the decibel meter T (such as Figure 5As shown), the test ball (temporarily placed), the vertical mounting stand above the support plate is provided with a relatively distributed and extended to the guide slot 4 of the support plate, the guide slot can be used to form a U-shaped channel steel on the upper part of the vertical mounting bracket. Of course, the vertical folding edges of the vertical plate-shaped vertical mounting bracket can also be welded to form a U-shaped slot. In order to increase the contact surface between the vertical folding edge and the test plate, the width of the first vertical folding edge 4-1 close to the bearing portion 5 is greater than the width of the second vertical folding edge 4-2 (see Figure 8 ), and in order to improve the structural stability, a transverse connecting portion 12 can be set between the two first vertical folds.

[0035] See also Figure 8-9 The fixing rod 8 arranged on the supporting plate is L-shaped, and a locking portion 11 is provided at the position where the L-shaped fixing rod passes through the bearing portion 5. The locking portion can be a locking structure of a screw and a nut. Since the bearing portion has a flat plate portion and a U-shaped protective portion arranged along the edge of the flat plate portion, the screw of the locking structure here can pass through the U-shaped protective portion, and the nut matched with the screw is installed close to the surface of the U-shaped protective portion. The fixing rod 8 is installed with a test ball mounting cantilever 9. When the test ball P on the test ball mounting cantilever is released, the test plate installed in the guide slot 4 can be knocked, and the decibel number can be tested by the decibel meter placed on the bearing portion 5.

[0036] It's worth noting that the support plate is equipped with flexible cushioning pads 6, made of materials including but not limited to rubber. Multiple, for example, two or more, rectangular cushioning pads can be distributed across the support plate to prevent interference noise between the metal support plate and the test board. Furthermore, anti-interference pads 7, also made of rubber or other flexible materials, are provided on the sidewalls of the guide slot. These pads can also prevent interference noise between the test board and the mounting slot, and improve the stability of the test board within the guide slot.

[0037] See also Figure 10The test ball mounting cantilever has a horizontal U-shaped fork 9-1, a fixed tail rod 9-2 arranged on the horizontal U-shaped fork, and a test ball placement plate 9-3 arranged at the front end of the horizontal U-shaped fork and capable of being opened and closed. This open structure is easy to assemble and maintain. The test ball P placed on the test ball placement plate is connected to the fixed tail rod via a rope 10. As an option, one end of the test ball placement plate is mounted on a side wall of the horizontal U-shaped fork via an axis (so that the test ball placement plate can rotate around the axis), and one end is mounted on the other side wall of the horizontal U-shaped fork via a pin 9-4 (when the pin is pulled out, the test ball placement plate rotates along the axis and the test ball falls from the test ball placement plate). In order to facilitate the adjustment of the striking position of the test ball, the horizontal U-shaped fork is symmetrically provided with fixed tail rod mounting bar holes. The fixed tail rod is adjustably mounted in the fixed tail rod mounting bar hole of the horizontal U-shaped fork via a screw and a nut. Here, the position where the test ball can touch the test plate 13 can be adjusted by moving the position of the fixed tail rod. From Figure 11-13 It can be seen that after the test board 13 is installed in place, the test ball hits the side of the test board where the noise reduction structure is not set ( Figure 13 The test board includes a test board body 13-1 and a noise reduction structure 13-2 provided on the test board body. Figure 11 As can be seen, the test board itself utilizes a vertical test board with a surrounding protective structure with an opening on one side. This allows the protective structure to be installed in place within the slot and also prevents the test board from being too thick, which can lead to poor test results. During testing, the noise reduction structure ensures that the test board fits snugly within the slot and prevents any shaking. When a test board without the noise reduction structure is positioned within the slot, an anti-interference pad of appropriate thickness can be used to prevent shaking.

[0038] It should be pointed out that an L-shaped fixing rod fixing seat is provided on the square supporting plate 3. The fixing seat is a cylinder with a vertical hole. Combined with the locking part 11 mentioned above, the test cantilever structure formed by the fixing rod 8 and the test ball mounting cantilever 9 can be well disassembled and assembled.

[0039] The method of using this test device is as follows:

[0040] 1. After moving the test device to the preset test site, secure the bracket to prevent the moving wheels from moving.

[0041] 2. Place the sample block into the guide slot 4 (the test sample block is a control group, and the test sample block is not provided with a noise reduction structure).

[0042] 3. Install the test cantilever structure as follows Figure 7 Install it in place.

[0043] 4. Turn on the decibel meter placed on the supporting part 5.

[0044] 5. Release the iron ball (test ball) locking device (i.e. pin 9-4), and the iron ball falls freely to hit the sample block.

[0045] 6. Record decibel values.

[0046] 7. Take out the sample.

[0047] 8. Place a structure containing sound insulation and noise reduction coating (i.e. Figure 11-12 The sample of the noise reduction structure 13-2) in the test plate (the back of the test plate has the sound insulation and noise reduction coating to be tested, which serves as the experimental group), pay attention to the coating surface facing the decibel meter, and repeat steps 4-7.

[0048] 9. Compare the measurement data and show the different decibel data obtained by the experimental group and the control group to the user.

[0049] This test device is only needed for non-professional laboratory testing and can be used for simple testing in factories and other places.

[0050] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present invention, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present invention.
