[0002] With the continuous advancement of urbanization, residents' demand for electricity resources is increasing. In order to provide residents with safe and reliable electricity supply, power facilities are beginning to be built more near residential areas. At the same time, the noise generated by the operation of power equipment will cause potential environmental pollution and health risks to surrounding residents.

[0045] Example 1

[0046] like Figure 1 As shown, the support structure for the electric noise monitoring device provided by the embodiment of the present invention includes a first support rod 1 arranged vertically, a second support rod 2 arranged horizontally, a mounting seat 3, a vibrator 92, a vibration sensor 91 and a control module (not shown in the figure). Among them, the right end of the second support rod 2 is fixed to support the noise monitoring device 4, the top area of ​​the first support rod 1 is connected to the left end of the second support rod 2, the mounting seat 3 is fixedly connected to the bottom area of ​​the first support rod 1, the mounting seat 3 is fixed on the side wall of the wall 6 close to the power equipment in the substation, and the control module is electrically connected to the vibration sensor 91 and the vibrator 92 respectively. Among them, the first support rod 1 and the second support rod 2 are both tubular structures, the vibrator 92 is installed on the second support rod 2 and is opposite to the position of the noise monitoring device 4; the vibration sensor 91 is installed at the bottom end of the one support rod, and the control module is fixed in the tubular structure of the second support rod 2.

[0047] It should be noted that the arrangement of the vibration sensor 91 is not restrictive, and according to practical applications, those skilled in the art may also arrange the vibration sensor 91 on the wall or other positions of the support structure.

[0048] Continue reading Figure 1 The support structure of the embodiment of the present invention further includes a first hinge connector 72, a second hinge connector 73 and an inclined auxiliary support rod 5. The upper end of the auxiliary support rod 5 is fixedly connected to the right end of the second support rod 2 through the first hinge connector 72, and the lower side end of the auxiliary support rod 5 is fixedly connected to the middle position of the first support rod 1 through the second hinge connector 73, so that the support structure forms a triangular structure to enhance the structural stability.

[0049] like Figure 1 As shown, the support structure of the embodiment of the present invention further includes a third hinge connector 71 , and the left end of the second support rod 2 is fixedly connected to the top area of ​​the first support rod 1 through the third hinge connector 71 .

[0050] During installation or maintenance, the second support rod 2 can be movably rotated to a lower position with the help of the third hinge connection 71 to facilitate the installation of the noise monitoring device 4, and then the second support rod 2 can be rotated to a horizontal direction with the help of the auxiliary support rod 5 to be fixed, thereby improving the convenience of installation and maintenance of the noise monitoring device 4.

[0051] like Figure 1 As shown, a fixed connection position is provided in the bottom area of ​​the first support rod 1, and a plurality of fixed connection positions are spaced apart along the length direction of the first support rod 1. The fixed connection positions at different positions on the first support rod 1 are fixedly connected to the other side of the mounting seat 3 to adjust the horizontal height of the first support rod 1.

[0052] Specifically, Figure 6 and Figure 7 As shown, the mounting seat 3 in the embodiment of the present invention includes two connecting plates 32 located on the side plate 31 and fixed on the same surface of the side plate 31. The two connecting plates 32 are arranged in parallel with each other at intervals, and each connecting plate 32 is provided with two locking holes 321 horizontally opposite to each other. Among them, the side plate 31 is provided with four through holes 311 respectively located at the corners, and the side plate 31 is provided with a strip-shaped wire hole 312, and the wire hole 312 is located between the two connecting plates 32. The expansion screw passes through the through hole 311 to fix the side plate 31 on the wall 6, and the thickness of the side plate 31 ranges from 4mm to 10mm. Among them, a wire groove 3121 connected to the wire hole 312 is provided on the surface of the side plate 31 away from the connecting plate 32.

[0053] like Figure 1 and Figure 8 As shown, a strip connecting rib 11 is provided in the bottom area of ​​the first support rod 1 along the length direction, and a plurality of height adjustment holes 111 are formed on the strip connecting rib 11 at the fixed connection position. The plurality of height adjustment holes 111 are evenly spaced and distributed, and the pin 8 passes through the height adjustment holes 111 and the lock hole 321 aligned horizontally and upwardly to fasten the connecting plate 32 to the strip connecting rib 11.

[0054] Specifically, Figure 8 As shown, the number of the strip-shaped connecting ribs 11 is two, and the two strip-shaped connecting ribs 11 are arranged in parallel. A side opening 13 is provided on the bottom area of ​​the first support rod 1, and the side opening 13 is located between the two strip-shaped connecting ribs 11. In the adjusted state, the two connecting plates 32 of the mounting seat 3 can move up and down relatively in the side opening 13. In addition, after the transmission line is laid through the wire hole 312 in the wire groove 3212, the transmission line can be located between the two connecting plates 32 and enter the pipeline in the second support rod 2 and the first support rod 1 through the side opening 13 to supply power to the noise monitoring device 4, avoiding exposure of the wiring to improve the safety and convenience of the wiring on the mounting seat 3, and also avoiding grooving on the wall 6 for wiring, meeting the on-site environmental construction requirements.

[0055] It should be noted that, according to actual applications, technicians in this field can adjust the number of through holes 311 on the basis of ensuring that the mounting base is firmly fixed, so as to reserve one of the through holes 311 for fixing the grounding wire to ensure the electrical safety of the noise monitoring device 4, vibrator 92, vibration sensor 91 and control module.

[0056] like Figure 1 As shown, the support structure further includes a handle 12 disposed on the first support rod 1. The handle 12 is disposed in the bottom plate area of ​​the first support rod 1. During installation and maintenance, the handle 12 assists workers to more conveniently adjust the height of the support structure.

[0057] It should be noted that the handle 12 is configured as a detachable structure, or the handle 12 can be fastened to a non-preset height adjustment hole 111 on the strip-shaped connecting rib 11 so that the handle 12 can be retracted after installation and maintenance.

[0058] like Figure 1 As shown, the support structure of the embodiment of the present invention further includes a mounting interface 74 disposed on one end of the second support rod 2 , and the noise monitoring device 4 is fixed on the mounting interface 74 .

[0059] It should be noted that the installation interface 74 is set upward, and the installation interface 74 can be set as a flange structure interface, or can also be set as a unified threaded port, or other forms of commonly used interface structures, as long as it is convenient for disassembly and maintenance of different models of noise monitoring devices 4.

[0060] It should be noted that the first support rod 1, the second support rod 2, and the auxiliary support rod 5 in the above-mentioned support structure are made of 304 stainless steel pipe, and the wall thickness of the stainless steel pipe is selected in the range of 1mm-3mm. Among them, the diameter of the first support rod 1 is not less than the diameter of the second support rod 2, the length of the second support rod 2 is at least 1m, and the inner diameter of the second support rod 2 is selected in the range of 40mm-80mm. In addition, the right port of the second support rod 2 and the top port of the first support rod 1 are respectively blocked to prevent the intrusion of rainwater and foreign objects. The bottom inner diameter of the first support rod 1 is larger than the inner diameter of the top plate, and the top inner diameter of the first support rod 1 is the same as the inner diameter of the second support rod 2.

[0061] When installing the noise monitoring device 4, with the help of the existing wall 6 in the environment, such as the building wall 6 around the electrical equipment, the bracket structure is fixed on the side wall of the wall 6 with the help of the mounting seat 3 to set up the fixed noise monitoring device 4, avoiding digging a hole in the ground to build the foundation of the first support rod 1, saving the installation cost of the noise monitoring device 4, and the bracket structure is simple and light, and the layout and installation are flexible. Moreover, during the installation or maintenance process, according to the actual application, the height of the bracket structure can be flexibly adjusted to meet the installation requirements of the noise monitoring device 4.

[0062] It can be understood that when the noise monitoring device 4 is in working state, the electrical equipment generates relatively strong noise, which in turn causes the surrounding walls 6 to vibrate. The vibration is transmitted to the support structure, making the noise monitoring device 4 prone to produce up and down vibrations of the same frequency. This up and down vibration of the same frequency affects the noise monitoring device 4's collection of environmental noise to a certain extent, thereby reducing the accuracy of the noise monitoring data.

[0063] The control module processes the vibration information collected by the vibration sensor 91 and obtains pulse information for the operation of the vibrator 92. The control module adjusts the pulse information according to the vibration information to control the vibrator 92 to balance and suppress the same-frequency vibration of the noise monitoring device 4 on the second support rod 2, thereby reducing the interference of the vibration on the collection work of the noise monitoring device 4 and improving the accuracy of the noise collection of the noise monitoring device 4. The vibrator 92 can be driven by electromagnetic mass block vibration or motor-driven vibration with a deflection wheel.

[0064] The working principle of the support structure is as follows: the vibration sensor 91 provided on the support structure is used to obtain vibration information such as vibration frequency and vibration displacement, and the control module calculates and processes the vibration frequency and vibration displacement to obtain the frequency and magnitude of the pulse current used for the vibrator 92 of the support structure to work;

[0065] The control module adjusts the frequency and size of the pulse current of the vibrator 92 according to the vibration frequency or vibration displacement to perform pulse operation to form damped vibration to balance and suppress the same-frequency vibration of the noise monitoring device 4 on the bracket structure, thereby reducing the interference of the same-frequency vibration on the noise collection of the noise monitoring device 4.

[0066] Example 2

[0067] like Figure 2 and Figure 3 As shown, compared with Example 1, the first support rod 1 in the support structure of the embodiment of the present invention includes a first lower support rod 101 and a first upper support rod 102. Among them, the right end of the second support rod 2 is fixed to the top area of ​​the first upper support rod 102, a plurality of fixed connections are located on the first lower support rod 101, the first lower support rod 101 and the first upper support rod 102 are fixedly connected by setting an axial adjustment connection member 75, and the handle 12 is fixed to the first lower support rod 101. The lower side end of the auxiliary support rod 5 is fixedly connected to the bottom end area of ​​the first upper support rod 102 through the second hinge connection member 73.

[0068] Specifically, Figure 2 , Figure 3 , Fig. 9 as well as Fig.10As shown, the axial adjustment connecting member 75 includes a first flange 751 and a second flange 752. The first flange 751 is installed on the upper end of the first lower section support rod 101, and the second flange 752 is installed on the lower end of the first upper section support rod 102. Six first positioning mounting holes 7511 are provided on the circumference of the first flange 751, and three second positioning mounting holes 7521 are provided on the circumference of the second flange 752.

[0069] like Figure 3 As shown, the position of the noise monitoring device 4 is installed or adjusted toward the horizontal left side so that the second positioning installation hole 7521 of the second flange 752 facing downward is aligned with the second positioning hole of the first flange 751, and the second flange 752 is fastened to the first flange 751 by means of fastening bolts to complete the orientation position setting requirements of the noise monitoring device 4.

[0070] It should be noted that, according to practical applications, technicians in this field can set the number of first positioning mounting holes 7511 to at least twice the number of second positioning mounting holes 7521, so as to ensure that the first positioning mounting holes 7511 can be docked with the second positioning mounting holes 7521, and the more the number of first positioning mounting holes 7511 is set, the more precise the horizontally adjustable angle control is.

[0071] In addition, according to actual applications, technical personnel in this field can also set the first flange 751 at the lower end of the first upper support rod 102, and the second flange 752 at the upper end of the first lower support rod 101, and other axial adjustment connecting parts 75 can also be used to replace the first lower support rod 101 and the first upper support rod 102, as long as the adjustment of the direction of the second support rod 2 can be achieved.

[0072] On the basis of Example 1, the support structure of this example also realizes the adjustment of the direction of the noise monitoring device 4, further meeting the setting requirements of the noise monitoring device 4.

[0073] It should be noted that other structures in the bracket structure of this embodiment are exactly the same as those in Embodiment 1, and therefore will not be described in detail here.

[0074] Example 3

[0075] like Figure 4 As shown, compared with the support structure in Example 2, the second support rod 2 of the support structure in the embodiment of the present invention is provided with a flange connector 76. The support structure does not use the auxiliary support rod 5 and the first hinge connector 72 and the second hinge connector 73 to save costs. The flange connector 76 is similar to the flange structure in Example 2, so it is not described here.

[0076] Compared with the support structure of the second embodiment, the second support rod 2 and the first upper support rod 102 in the support structure of this embodiment are simple and convenient to assemble and disassemble.

[0077] It should be noted that other structures in the bracket structure of this embodiment are exactly the same as those in Embodiment 2, and therefore will not be described in detail here.

[0078] Example 4

[0079] like Figure 5 As shown, compared with the bracket structure in Example 3, the bracket structure in this embodiment simplifies the structure of the mounting seat, and the mounting seat 3 includes a side plate and a connecting rod fixed to the side plate, and the connecting rod is directly fixed to the lower end of the first support rod 1. The bracket structure adopts an auxiliary support rod 5 and a first hinge connector 72 and a second hinge connector 73 to enhance the stability of the bracket structure. Among them, only a single vertically arranged first support rod 1 is used in the bracket structure.

[0080] Compared with the bracket structure of Example 3, the bracket structure of this embodiment is simple and low in cost.

[0081] It should be noted that other structures in the bracket structure of this embodiment are exactly the same as those in Embodiment 3, so they will not be described here in detail.

[0082] Example 5

[0083] Based on the same inventive concept, the present invention also provides a control method for the support structure of the power noise monitoring device in Embodiments 1 to 4, the control method comprising:

[0084] S1, obtaining vibration information using a vibration sensor 91 disposed on the support structure;

[0085] S2, the control module calculates and processes the vibration information to obtain a pulse current for the vibrator 92 of the support structure to work;

[0086] S3. The control module adjusts the pulse current according to the vibration information to control the vibrator 92 to perform pulse vibration to balance and suppress the same-frequency vibration of the noise monitoring device 4 on the support structure.

[0087] The steps of S2 specifically include:

[0088] S21, the control module converts the frequency in the vibration information into the frequency value of the pulse current of the vibrator 92, and the frequency period of the pulse current is opposite to the frequency period of the vibration information.

[0089] S22 , the control module converts the vibration displacement in the vibration information into a pulse current value for the operation of the vibrator 92 .

[0090] It can be understood that the frequency period of the pulse current of the vibrator 92 is adjusted to be opposite to the frequency period of the vibration of the wall 6 to achieve damped interference vibration so that the noise monitoring device 4 vibrates at the same frequency on the support structure, and the pulse current size is adjusted to balance the amplitude size of the noise monitoring device 4 on the support structure.

[0091] Specifically, the steps of S3 include:

[0092] S31, when the vibration frequency is within the set frequency threshold range, the control module controls the vibrator 92 to start and the vibrator 92 operates at the frequency value and pulse current value of the pulse current;

[0093] S32: When the vibration frequency is less than the set frequency threshold range, the control module controls the vibrator 92 to stop working.

[0094] It can be understood that when the vibration of the wall 6 generated by the electrical equipment in the substation has an adverse effect on the noise monitoring device 4 on the support structure, the vibrator 92 is started to balance and suppress the vibration of the support structure. When the vibration of the wall 6 is reduced to a certain frequency range and does not affect the collection work of the noise monitoring device 4 on the support structure, the vibrator 92 stops working.

[0095] The step of S31 includes:

[0096] S311, if the vibration displacement is greater than the set displacement threshold, the control module adjusts and increases the pulse current value of the vibrator 92;

[0097] S312 , if the vibration displacement is less than the displacement threshold, the control module adjusts and reduces the pulse current value of the vibrator 92 .

[0098] S313: If the vibration displacement is equal to the displacement threshold, the pulse current value of the vibrator 92 is kept unchanged.

[0099] It is understandable that in order to maintain the vibrator 92 and the wall 6 vibrating at the same frequency and opposite to each other, the frequency value of the pulse current is relatively constant. Therefore, the amplitude of the vibrator 92 is adjusted by adjusting the pulse current value to balance the amplitude of the noise monitoring device 4 on the support structure.

[0100] Through such a setting, the support structure can achieve autonomous balance to suppress the vibration transmitted by the wall 6, thereby allowing the noise monitoring device 4 to maintain a relatively stable state on the support structure, avoiding excessive swinging of the noise monitoring device 4 and reducing the noise collection effect of the noise monitoring device 4.

[0101] The above are merely embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are included in the scope of the claims of the present invention.
