Description

Technical Field

[0001] This utility model relates to the field of noise statistics technology, specifically to a high-precision noise statistics analysis device. Background Technology

[0002] A noise analysis device, also known as a noise analyzer or noise meter, is an instrument used to monitor and analyze noise to obtain various noise parameters. The main parameter of noise is decibels. Using a noise analyzer, the noise source can be located, and the obtained parameters can guide relevant intervention measures to minimize the consequences of noise.

[0003] Existing analytical devices fix the device to the ground via a bracket, and then adjust the noise receiving end of the device to the noise location via an adjustment mechanism. The noise is then analyzed by a noise receiving sensor. However, when the adjustment mechanism adjusts the noise receiving end, the receiving head is easily affected by wind, resulting in data deviation and affecting the integrity of the statistical analysis of noise data.

[0004] The aforementioned analysis device suffers from data deviation due to the receiver head being easily affected by adjustments, which compromises the integrity of the statistical noise data and reduces the device's effectiveness. Utility Model Content

[0005] This invention proposes a high-precision noise statistical analysis device to solve the problem in the prior art where the receiving head is easily affected by wind when it moves through the adjustment mechanism, resulting in data deviation.

[0006] The technical solution of this utility model is as follows: A high-precision noise statistical analysis device, including a fixed tube, and further comprising:

[0007] The connecting shaft is rotatably connected inside the fixed tube. A mounting plate is installed at the top of the connecting shaft. The movable block is slidably connected inside the mounting plate. A connecting pin is threaded through the upper surface of the movable block. One end of the connecting pin, which is inserted into the movable block, abuts against the mounting plate. The support frame is installed on the upper surface of the movable block. A protective tube is installed on the inner side of the support frame. A first connecting piece is installed on the side of the protective tube. A first shielding piece is slidably connected inside the first connecting piece. A guide block is installed on the side of the first shielding piece. A second connecting piece is installed on the side of the protective tube. A second shielding piece is slidably connected inside the second connecting piece. The fixing pin is threaded through the outer surface of the fixed tube. One end of the fixing pin, which is inserted into the fixed tube, abuts against the connecting shaft.

[0008] In a preferred embodiment of the high-precision noise statistical analysis device of this utility model, in order to better adjust the position of the moving tube, the outer surface of the fixed tube is slidably connected to the moving tube, and the outer surface of the moving tube is threaded with a plug pin.

[0009] In a preferred embodiment of the high-precision noise statistical analysis device of this utility model, in order to prevent the moving tube from becoming loose after it is fixed, one end of the insertion pin that passes through the moving tube abuts against the fixed tube.

[0010] In a preferred embodiment of the high-precision noise statistical analysis device of this utility model, in order to facilitate the adjustment of the position of the support rod, a first connecting frame is installed on the outer surface of the moving tube, and the support rod is rotatably connected inside the first connecting frame.

[0011] In a preferred embodiment of the high-precision noise statistical analysis device of this utility model, in order to facilitate the adjustment of the support plate according to the ground angle, a connecting rod is rotatably connected inside the support rod, a second connecting frame is rotatably connected to the outer surface of the connecting rod, an auxiliary tube is installed on the outer surface of the second connecting frame, and a support plate is installed on the lower surface of the second connecting frame.

[0012] In a preferred embodiment of the high-precision noise statistical analysis device of this utility model, in order to facilitate the rotation of the connecting rod, the connecting rod is rotatably connected inside the auxiliary tube, and an auxiliary pin is provided on the outer surface of the auxiliary tube, with one end of the auxiliary pin inserted into the auxiliary tube abutting against the connecting rod.

[0013] The working principle and beneficial effects of this utility model are as follows:

[0014] In this invention, by manipulating the moving block to move inward along the mounting plate, the protective tube moves to the outside of the sensor head and wraps around it. Compared with the prior art of directly adjusting the device position, this device can minimize the impact of wind on the accuracy of the noise data received by the device and enhance the integrity of the noise data received by the device.

[0015] In this invention, by moving the first and second blocking plates inward along the first and second connecting plates respectively, the second blocking plate blocks the right side of the sensor head. Compared with the prior art of directly changing the receiving direction, this device can prevent wind from entering the protective tube during the rotation of the mounting plate, thus affecting the signal received by the sensor head and improving the effectiveness of the device.

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. 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 of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0023] like Figures 1-4 As shown, this embodiment proposes a high-precision noise statistical analysis device, including a fixed tube 1, a connecting shaft 2, a mounting plate 3, a moving block 4, a connecting pin 5, a support frame 6, a protective tube 7, a first connecting piece 8, a first shielding piece 9, a guide block 10, a second connecting piece 11, a second shielding piece 12, and a fixed pin 13.

[0024] like Figure 4As shown, the connecting shaft 2 is rotatably connected inside the fixed tube 1. A mounting plate 3 is installed at the top of the connecting shaft 2. The moving block 4 is slidably connected inside the mounting plate 3. A connecting pin 5 is threaded through the upper surface of the moving block 4. One end of the connecting pin 5, inserted into the moving block 4, abuts against the mounting plate 3. A support frame 6 is installed on the upper surface of the moving block 4. A protective tube 7 is installed on the inner side of the support frame 6. A first connecting piece 8 is installed on the side of the protective tube 7. A first shielding piece 9 is slidably connected inside the first connecting piece 8. After the first shielding piece 9 moves inward to its maximum range, a certain gap still exists on the inner side of the first shielding piece 9 to receive noise signals. The side of the first shielding piece 9... A guide block 10 is installed to guide the wind received by the device during rotation outward. The second connecting piece 11 is installed on the side of the protective tube 7. The second shielding piece 12 is slidably connected inside the second connecting piece 11. When the second shielding piece 12 moves inward, it can completely close, fixing the extension rod connected to the sensing head and reducing the number of times wind enters the protective tube 7. The fixing pin 13 is threaded through the outer surface of the fixing tube 1. One end of the fixing pin 13 that enters the fixing tube 1 abuts against the connecting shaft 2. It should be noted that all the mechanisms mentioned above are in pairs, and they can contact each other to form a complete mechanism during inward movement.

[0025] like Figure 2 As shown, a movable tube 14 is slidably connected to the outer surface of the fixed tube 1. When the device is not in use, the movable tube 14 is located in the upper middle position of the fixed tube 1, and the support rod 17 is in contact with the fixed tube 1, forming a retracted shape. Figure 2 With the support rod 17 in the unfolded state, a threaded insertion pin 15 is threaded through the outer surface of the moving tube 14. One end of the insertion pin 15, which is inserted into the moving tube 14, abuts against the fixed tube 1. A first connecting frame 16 is installed on the outer surface of the moving tube 14. A support rod 17 is rotatably connected inside the first connecting frame 16. A connecting rod 18 is rotatably connected inside the support rod 17. A second connecting frame 19 is rotatably connected to the outer surface of the connecting rod 18. An auxiliary tube 20 is installed on the outer surface of the second connecting frame 19. The device rotates along the support rod 17 via the second connecting frame 19 and the connecting rod 18, allowing the operator to adjust the support plate 22 according to the ground angle. To prevent the device from tilting after unfolding, a support plate 22 is installed on the lower surface of the second connecting frame 19. The connecting rod 18 is rotatably connected inside the auxiliary tube 20. An auxiliary pin 21 is threaded through the outer surface of the auxiliary tube 20. One end of the auxiliary pin 21, which is inserted into the auxiliary tube 20, abuts against the connecting rod 18.

[0026] In this embodiment, as Figure 3 As shown, an auxiliary rod 23 runs through the interior of the fixed tube 1, and the top end of the auxiliary rod 23 is mounted on the lower surface of the connecting shaft 2, as shown. Figure 1As shown, a noise sensor 24 is mounted on the upper surface of the mounting plate 3 by bolts, and a display screen 25 is mounted on the upper surface of the mounting plate 3. A sensing head is mounted on the left side of the noise sensor 24. The noise sensor 24 and the display screen 25 are connected by a transmission line. The noise sensor 24 receives noise through the sensing head and transmits the received noise data to the display screen 25 through the transmission line. The display screen 25 then displays the data for the operator to view and analyze. It should be noted that both the display screen 25 and the noise sensor 24 require an external power supply.

[0027] In this embodiment, the noise sensor 24 and the display screen 25 are fixed on the upper surface of the mounting plate 3. The noise sensor 24 and the display screen 25 are connected through a transmission line. The device is moved to the placement location. The insertion pin 15 is loosened counterclockwise. The moving tube 14 is manipulated to move downward along the fixed tube 1. The support rod 17 is manipulated to flip outward and unfold. The moving tube 14 moves downward, causing the first connecting frame 16 to move downward. The first connecting frame 16 moves downward, causing the support rod 17 to move downward. After the movement is complete, the insertion pin 15 is tightened clockwise. The support rod 17 flips outward, causing the connecting rod 18 to flip outward. The connecting rod 18 flips outward, causing the second connecting frame 19 to flip outward. The auxiliary pin 21 is pulled out, so that the support plate 22 is in contact with the ground. After adjustment, the auxiliary pin 21 is manipulated to pass through the auxiliary tube 20 and press against the connecting rod 18.

[0028] Powering on the noise sensor 24 allows the sensing head to receive noise. The data is then transmitted to the display screen 25 via a transmission line for display and analysis. When the position of the sensing head needs to be adjusted, the connecting pin 5 is loosened counterclockwise. The moving block 4 is then moved inward along the mounting plate 3. The inward movement of the moving block 4 causes the support frame 6 to move inward, which in turn causes the protective tube 7 to move inward. The inward movement of the protective tube 7 causes the first connecting piece 8 and the second connecting piece 11 to move inward, making the two sets of first connecting pieces 8 and second connecting pieces 11 contact each other. This allows the protective tube 7 to protect the sensing head. The auxiliary rod 23 is then rotated, causing the connecting shaft 2 to rotate. The rotation of the connecting shaft 2 causes the mounting plate 3 to rotate, adjusting the receiving direction of the sensing head. After adjustment, the above operation is reversed, exposing the sensing head.

[0029] When the sensor head rotates too much, the first blocking plate 9 is moved inward along the first connecting plate 8. The inward movement of the first blocking plate 9 causes the guide block 10 to move inward. The second blocking plate 12 is moved inward along the second connecting plate 11. The inward movement of the second blocking plate 12 fixes the extension rod of the sensor head. Then the mounting plate 3 is rotated to change the direction.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
