Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment, in particular to a distribution transformer stand terminal protection device. Background Art

[0002] During the bird breeding season, birds often stay on the distribution transformer racks, and even build bird nests on the distribution transformer racks. The high-voltage incoming wires and low-voltage outgoing wires on the distribution transformer racks are insulated, but the terminals where the high-voltage incoming wires and low-voltage outgoing wires are connected to the distribution transformer are exposed. Birds staying at the terminals may get electric shocks, causing the transmission line to trip, and the bird droppings sticking to the terminals will accelerate the rust and corrosion of the terminals. Utility Model Content

[0003] Therefore, in view of the above-mentioned problems, the utility model proposes a distribution transformer stand terminal protection device, which can monitor whether there are birds near the terminal and drive them away in time, thereby protecting the terminal.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A distribution transformer rack terminal protection device includes a controller, an ultrasonic generator, a plurality of waterproof sound sensors distributedly installed on the distribution transformer rack, and infrared sensors distributedly installed on the distribution transformer rack near each terminal;

[0006] The detection range of each infrared sensor should cover the position of the wiring terminal closest to it;

[0007] The controller includes a power supply module, a processor and a spectrum analysis circuit module;

[0008] The power module is electrically connected to the power terminal of the processor, the spectrum analysis circuit module, the ultrasonic generator, and each infrared sensor are electrically connected to the I / O terminal of the processor, and each waterproof sound sensor is electrically connected to the spectrum analysis circuit module.

[0009] Furthermore, the controller also includes a wireless communication module; the wireless communication module is electrically connected to the communication end of the processor.

[0010] Furthermore, the wireless communication module also includes any one or a combination of a 3G communication module, a 4G communication module, a 5G communication module, and a NB-IOT communication module.

[0011] Furthermore, it also includes a monitoring camera, and the monitoring video collected by the monitoring camera should cover each terminal on the distribution transformer stand;

[0012] The monitoring camera is electrically connected to the communication end of the processor.

[0013] Furthermore, the power module adopts solar cells.

[0014] By adopting the above technical solution, the beneficial effects of the utility model are:

[0015] The sound spectrum of bird calls of different species of birds is different. The species of birds can be determined by analyzing the sound spectrum of bird calls. Different birds are driven away by ultrasonic waves of different frequencies. Based on this, the terminal protection device of the distribution transformer rack detects whether there are birds staying near the terminals on the distribution transformer rack through infrared sensors and waterproof sound sensors. If there are birds staying, the type of birds is further analyzed and determined, and then the ultrasonic generator is controlled to emit ultrasonic waves of different frequencies according to different birds to drive away the birds and prevent them from staying, which can protect the terminals.

[0016] Furthermore, if the birds are still not driven away after ultrasonic repels (i.e., birds are detected to be staying at each terminal position), the monitoring screen is collected by the monitoring camera, and if it exceeds a certain number of times, it is judged that the device may have a fault, and the wireless communication module sends information and monitoring screen data to the staff or the background terminal to facilitate personnel to check and promptly go to the site for maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 It is a structural schematic diagram of the utility model.

[0018] Figure 2 It is a circuit connection diagram. DETAILED DESCRIPTION

[0019] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0020] refer to Figure 1 and Figure 2 The present embodiment provides a distribution transformer rack terminal protection device, including an ultrasonic generator 1, a plurality of waterproof sound sensors 2 distributedly installed on the distribution transformer rack 100, infrared sensors 3 distributedly installed on the distribution transformer rack 100 near each terminal 101, a monitoring camera 4 arranged on the distribution transformer rack 100, and a controller 5.

[0021] The above-mentioned distribution transformer rack 100 is an existing device, and the present invention does not improve the structure of the distribution transformer rack 100. The connection terminal 101 is a port for connecting the high-voltage incoming wire and the low-voltage outgoing wire to the distribution transformer.

[0022] The installation positions of the waterproof sound sensor 2, infrared sensor 3 and surveillance camera 4 are installed according to the actual installation scene, but should meet the following conditions:

[0023] Each of the waterproof sound sensors 2 is used to collect bird calls near each terminal 101 on the distribution transformer stand 100;

[0024] The detection range of each infrared sensor 3 should cover the position of the connection terminal 101 closest to it on the distribution transformer stand 100;

[0025] The monitoring video collected by the monitoring camera 4 should cover each terminal 101 on the distribution transformer stand 100 .

[0026] The controller 5 includes a processor 51 , a power module 52 , a spectrum analysis circuit module 53 and a wireless communication module 54 .

[0027] In this specific embodiment, preferably, the processor 51 adopts an ESP32 single-chip microcomputer, the power module 52 adopts a solar cell, and the wireless communication module 54 also includes any one or a combination of a 3G communication module, a 4G communication module, a 5G communication module, and a NB-ioT communication module. The spectrum analysis circuit module 53 is used to receive the sound collected by the waterproof sound sensor 2, and analyze the spectrum of the sound and transmit it to the processor 51. The processor 51 is preset with the spectrum information of each total bird call, and the spectrum of the sound transmitted by the spectrum analysis circuit module 53 is compared to determine whether it is a bird call. The above-mentioned electronic components are all existing equipment, and those skilled in the art should have the conventional selection ability of the above-mentioned electronic components, and those skilled in the art can fully reproduce the distribution transformer stand terminal protection device disclosed in this patent application after a limited number of circuit connection experiments based on this specification and the drawings of the specification, and produce the same technical effect. The utility model does not involve the improvement of computer programs.

[0028] The connection method between the above electronic components is:

[0029] The power module 52 is electrically connected to a power terminal of the processor 51 to supply power to the processor 51 .

[0030] The spectrum analysis circuit module 53, the ultrasonic generator 1, and each infrared sensor 3 are electrically connected to the I / O terminal of the processor, respectively; the monitoring camera 4 and the wireless communication module 54 are electrically connected to the communication terminal of the processor, respectively; and each waterproof sound sensor 2 is electrically connected to the spectrum analysis circuit module 53, respectively.

[0031] Since the sound spectrum of bird calls from different species of birds is different, the sound is collected by the waterproof sound sensor 2, and the spectrum of the collected sound is further analyzed to determine whether it is a bird call and the type of bird. Different birds are driven away by ultrasonic waves of different frequencies. However, due to the influence of noise in the surrounding environment, misjudgment may occur. Therefore, this solution is equipped with an infrared sensor 3 to detect whether there are creatures approaching the positions of the terminals 101 on the distribution transformer stand 100. If the infrared sensor 3 detects that there are creatures approaching the positions of the terminals 101 on the distribution transformer stand 100, and the sound is collected by the waterproof sound sensor 2 and further analyzed as a bird call, the ultrasonic generator 1 is controlled to emit ultrasonic waves of different frequencies according to different birds to drive away the birds and prevent the birds from staying, which can protect the terminals 101.

[0032] If the birds are still not driven away by ultrasonic repelling (i.e., birds are detected to be staying at each terminal 101), the monitoring screen is collected by the monitoring camera 4, and if it exceeds a certain number of times, it is determined that the device may have a fault, and information and monitoring screen data are sent to the staff or the background terminal through the wireless communication module 54, so that the staff can check and go to the site for maintenance in time.

[0033] The power module 52 can also be connected to the low-voltage outgoing wire of the transformer on the distribution transformer rack 100 using a power adapter.

[0034] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
