Description

Technical Field

[0001] This utility model relates to the field of substation safety detection technology, specifically a substation safety detection alarm device. Background Technology

[0002] As the core hub of the power system, the operating status of substation equipment directly affects the safety of the power grid and the reliability of power supply. Equipment overheating is a significant symptom that can lead to malfunctions or even fires. Therefore, real-time temperature monitoring of critical equipment within the substation (such as transformers, switchgear, busbar joints, etc.) is of paramount importance.

[0003] Substations commonly use infrared thermal imagers for non-contact temperature monitoring. However, infrared thermal imagers usually need to be observed through a transparent protective cover (such as a glass or acrylic shell). In the complex environment of substations, such as dust and humidity, dust, oil or water vapor can easily accumulate on the surface of the protective cover. These deposits will seriously attenuate the infrared radiation signal, resulting in a decrease in the detection accuracy and sensitivity of the thermal imager.

[0004] Therefore, those skilled in the art have proposed a substation safety detection and alarm device to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a substation safety detection and alarm device that solves the problem in the prior art where the surface of the protective cover used to protect infrared thermal imagers is affected by the impact on detection accuracy.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A substation safety detection and alarm device, comprising:

[0008] An mounting plate is fixedly connected to a mounting column on its top. A transparent shell is fixedly connected to the top of the mounting column. An infrared thermal imager is located inside the mounting column and inside the transparent shell. A controller is provided on the surface of the mounting column. A buzzer is provided on the top of the controller. A face recognition device is provided on the surface of the mounting column.

[0009] A cleaning component, disposed inside the mounting post, is used to clean the surface of the transparent shell;

[0010] The mounting assembly is disposed on the surface of the mounting plate and is used to mount the device in the desired location.

[0011] Preferably, the cleaning component includes a connecting ring rotatably connected to the top of the mounting column, an internal gear ring fixedly connected to the inner side of the connecting ring, a motor disposed inside the mounting column, and a gear fixedly connected to the output shaft of the motor, the gear meshing with the internal gear ring.

[0012] Preferably, a connecting rod is fixedly connected to the top of the connecting ring, and a cleaning block is fixedly connected to the inner side of the connecting rod, with the cleaning block in contact with the surface of the transparent shell.

[0013] Preferably, the mounting assembly includes a plurality of mounting holes formed on the top of the mounting plate and arranged in a ring, the top of the mounting plate is provided with uniformly distributed mounting blocks, and the bottom of the mounting blocks is fixedly connected with threaded posts corresponding to the mounting holes.

[0014] Preferably, the top of the mounting plate has evenly distributed mounting grooves that are coaxially arranged with the adjacent mounting holes, and the inner wall of the mounting groove is fixedly connected to a mounting ring, the top of the mounting ring having a resistance-increasing groove.

[0015] Preferably, the diameter of the mounting block is larger than the diameter of the threaded post, the mounting block has a fixing cavity inside, a resistance-increasing plate is slidably connected to the inner wall of the fixing cavity, the resistance-increasing plate is a rubber material component, the lower end of the resistance-increasing plate passes through the mounting block, and a spring is fixedly connected between the top of the resistance-increasing plate and the inner wall of the fixing cavity.

[0016] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0017] 1. By setting up a cleaning component, the motor can be remotely activated via the controller to drive the gear and internal gear ring to rotate the connecting ring. This, in turn, drives the connecting rod to clean the surface of the transparent shell with a cleaning block, preventing dust and impurities from affecting the detection results of the infrared thermal imager. During use, the controller is equipped with a remote transmission module to transmit the corresponding signals to the control room for inspection by staff. After the staff investigating abnormal heat sources have finished their on-site investigation, they need to use facial recognition equipment to identify the staff member before the controller can shut off the continuous alarm of the buzzer.

[0018] 2. By setting up the mounting components, the device can be installed in the required position. Due to the spring, the resistance plate is pressed tightly against the mounting ring. Because the mounting ring has resistance grooves, the deformed resistance plate, in conjunction with the resistance grooves, can increase the friction force of the threaded column reversing, thereby preventing the threaded column from reversing.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 A substation safety detection and alarm device, comprising:

[0027] Mounting plate 1, mounting post 101 is fixedly connected to the top of mounting plate 1, transparent shell 102 is fixedly connected to the top of mounting post 101, infrared thermal imager 103 is located inside mounting post 101 and inside transparent shell 102, controller 201 is provided on the surface of mounting post 101, buzzer 202 is provided on the top of controller 201, and face recognition device 2 is provided on the surface of mounting post 101.

[0028] Cleaning component 3 is disposed inside the mounting post 101 and is used to clean the surface of the transparent shell 102;

[0029] Mounting component 4 is disposed on the surface of mounting plate 1 and is used to install the device in the desired location.

[0030] The infrared thermal imager 103 is used to detect the internal equipment of the substation. The infrared thermal imager 103 detects the temperature of the internal equipment of the substation. When an abnormal heat source is detected, the infrared thermal imager 103 transmits the signal to the controller 201. The controller 201 activates the buzzer 202 to sound an alarm. At the same time, the controller 201 is equipped with a remote transmission module to transmit the corresponding signal to the control room for staff to check. After the staff who are investigating the abnormal heat source have finished their investigation, they need to use the facial recognition device 2 to identify themselves. Only after confirming that they are staff can the controller 201 turn off the continuous alarm of the buzzer 202.

[0031] Please see Figure 1-5 The cleaning component 3 includes a connecting ring 301 rotatably connected to the top of the mounting post 101. An internal gear ring 303 is fixedly connected to the inner side of the connecting ring 301. A motor 302 is installed inside the mounting post 101. A gear 304 is fixedly connected to the output shaft of the motor 302. The gear 304 meshes with the internal gear ring 303.

[0032] A connecting rod 305 is fixedly connected to the top of the connecting ring 301, and a cleaning block 306 is fixedly connected to the inner side of the connecting rod 305. The cleaning block 306 is in contact with the surface of the transparent shell 102.

[0033] By starting the motor 302, the gear 304 drives the internal gear ring 303 to rotate the connecting ring 301, which in turn drives the connecting rod 305 to clean the surface of the transparent shell 102 with the cleaning block 306, thus preventing dust and impurities from affecting the detection results of the infrared thermal imager 103.

[0034] Please see Figure 1-5 The mounting component 4 includes several mounting holes that are opened on the top of the mounting plate 1 and are distributed in a ring. The top of the mounting plate 1 is provided with evenly distributed mounting blocks 401, and the bottom of the mounting blocks 401 is fixedly connected with threaded posts 402 corresponding to the mounting holes.

[0035] The top of the mounting plate 1 has evenly distributed mounting grooves that are coaxial with the adjacent mounting holes. The inner wall of the mounting groove is fixedly connected to a mounting ring 405, and the top of the mounting ring 405 has a resistance-increasing groove 406.

[0036] The diameter of the mounting block 401 is larger than the diameter of the threaded post 402. The mounting block 401 has a fixed cavity inside. A resistance-increasing plate 403 is slidably connected to the inner wall of the fixed cavity. The resistance-increasing plate 403 is a rubber material component. The lower end of the resistance-increasing plate 403 passes through the mounting block 401. A spring 404 is fixedly connected between the top of the resistance-increasing plate 403 and the inner wall of the fixed cavity.

[0037] By pre-drilling threaded holes at the required installation location, aligning the mounting holes of the mounting plate 1 with the threaded holes, and then threading the threaded post 402 through the mounting holes to connect with the pre-drilled threaded holes, the red mounting block 401 can gradually approach the mounting plate 1 and cooperate to press the mounting plate 1 against the mounting surface, thereby achieving the positioning of the device. At the same time, during the installation of the threaded post 402, the resistance plate 403 can gradually be inserted into the interior of the mounting groove, and the resistance plate 403 is in close contact with the surface of the mounting ring 405. Since the resistance plate 403 is a rubber material component with a certain deformation capacity, and the spring 404 is set so that the resistance plate 403 is in close contact with the mounting ring 405, and because the mounting ring 405 has a resistance groove 406, the deformed resistance plate 403, in conjunction with the resistance groove 406, can increase the friction force of the threaded post 402 in reverse rotation, thereby preventing the threaded post 402 from reversing.

[0038] Working principle: By setting the installation component 4, the device can be installed at the required detection location. The infrared thermal imager 103 detects the temperature of the equipment inside the substation. When an abnormal heat source is detected, the infrared thermal imager 103 transmits the signal to the controller 201. The controller 201 activates the buzzer 202 to sound an alarm. At the same time, the controller 201 is equipped with a remote transmission module to transmit the corresponding signal to the control room for inspection by the staff. After the staff who are investigating the abnormal heat source have finished their investigation, they need to be identified by the facial recognition device 2. Only after being identified as staff can the controller 201 turn off the continuous alarm of the buzzer 202. By starting the motor 302, the gear 304 drives the internal gear ring 303 to rotate the connecting ring 301, which in turn drives the connecting rod 305 to clean the surface of the transparent shell 102 with the cleaning block 306, so as to prevent dust and impurities from affecting the detection results of the infrared thermal imager 103.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
