[0002] Usually, two or three fire extinguishers are placed in a fire extinguisher box in a substation. The fire extinguisher box adopts a glass cover and an aluminum alloy frame design, which makes the fire extinguisher box bulky and prone to aging and cracking over time.

[0003] Maintenance personnel need to check the pressure of fire extinguishers regularly every month. Due to the narrow space, deepness and low transparency of the box, maintenance personnel cannot directly observe the pressure indicated by the pointer of the fire extinguisher after opening the box cover. They need to lift the fire extinguisher to view it, which is time-consuming and laborious. In addition, maintenance personnel need to fill out maintenance cards for each fire extinguisher every month. For a 220kV substation, there are nearly 100 fire extinguishers in the station, and nearly 50 for a 110kV substation. This inspection and maintenance mode increases the work pressure of maintenance personnel and cannot meet the current situation of intelligent transformation of substations.

[0004] In order to adapt to the development level of intelligent operation and maintenance of substations and achieve the goal of remote intelligent monitoring without on-site inspection for fire protection maintenance, it is necessary to develop a substation fire extinguisher storage and intelligent monitoring system, which is lightweight and has the functions of fire extinguisher pressure monitoring and electronic maintenance card generation, reducing the number of on-site inspections by personnel and fundamentally alleviating the work pressure of operation and maintenance personnel in fire protection maintenance.

DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0024] like Figure 1 As described above, the embodiment of the present invention provides a substation fire extinguisher storage monitoring device, comprising a box body 1, a box cover is hinged on the box body, and a sealing ring is provided on the contact surface between the box cover and the box body; The fire extinguisher 2 is arranged in the box 1, and a pressure detection module 8 is arranged on the fire extinguisher 1, and each pressure detection module is provided with a code corresponding to the fire extinguisher; A control module and an information transmission module are also provided in the box, and a display module 3 is provided on the box; the display module and the pressure detection module are connected to the control module; the pressure detection module detects the pressure information of the fire extinguisher and transmits the detection information and the corresponding coding information to the control module, and the control module displays the pressure of each fire extinguisher on the display module; The control module is connected to the information transmission module, and the control module transmits the detected fire extinguisher pressure information to the remote management platform through the information transmission module.

[0025] It should be noted that a lid handle is provided in the center of the lid; Box handles 4 are provided on both sides of the box body 1; A roller 5 with a braking function is arranged below the box body 1 .

[0026] A heat insulation layer 6 is embedded inside the box body 1, and a gap is left between the heat insulation layer and the box body; A waterproof layer is arranged outside the box.

[0027] It should be noted that the box body is made of anti-exposure material, which will not age even outdoors, and the box body is lightweight as a whole, which is convenient for operation and maintenance personnel to move the box body and temporarily place it at the maintenance site. The box cover is located above the box body, connected to the box body through a sealing ring, and is equipped with a buckle. The contact part between the box cover and the box body is surrounded by a sealing material to prevent rainwater from entering. The handle of the box cover is located in the center of the box cover. It adopts a cylindrical handle instead of the traditional flat handle, which increases the contact surface with the palm, reduces the pressure, and is convenient for operation and maintenance personnel to open. The box handles are located on both sides of the box body, which is convenient for operation and maintenance personnel to move the box body on uneven roads or up and down stairs. The roller with a brake function under the box body is convenient for personnel to move and fix the box body on flat ground. The box body is embedded with a heat insulation layer, and a gap is left between the box body to isolate the outside air, keep the temperature inside the box from overheating or overcooling, and achieve the effect of warm in winter and cool in summer, resulting in no change in the pressure of the fire extinguisher. The entire cabinet is painted with a layer of waterproof material. Even if cracks appear in the cabinet during transition collision, the waterproof material has a certain elasticity and will prevent leakage.

[0028] A solar panel is provided on the top of the box cover, and a power supply module is also provided in the box body, which are connected to the display module and the control module respectively. The fire extinguisher box arranged outdoors can automatically switch to the solar cell power supply mode to ensure that the battery has power for a long time and achieve long-term operation. Since the position of the fire extinguisher in the station is relatively fixed, a USB plug is connected to the back of the box body, which can be conveniently charged to charge the rechargeable battery, so that it can be used while charging. Even if the power is lost in the station, the battery capacity of the rechargeable battery can make the device last for one month, meeting the needs of the operation and maintenance personnel to conduct a comprehensive inspection of the substation once a month.

[0029] In some embodiments, the control module sends information to activate the pressure detection module periodically or after receiving external trigger information. The activated pressure detection module detects the pressure information of the fire extinguisher and transmits the detection information and corresponding coding information to the control module.

[0030] In some embodiments, the display has a touch function, can display the pressure value of each fire extinguisher in real time, and can check the maintenance records.

[0031] The pressure detection module is screwed to the original pressure gauge position of the fire extinguisher through fixing bolts; The pressure detection module includes a pressure sensor and a communication module; The pressure sensor collects the pressure value of the fire extinguisher and transmits the collected pressure value to the control module through the communication module.

[0032] It should be noted that the pressure detection module is composed of six parts: a fixing bolt, a bolt sleeve, a pressure sensor, a communication module, a power module, and a shell; the fixing bolt adopts a full copper thread design, which matches the pressure gauge of the fire extinguisher. By unscrewing the pressure gauge of the fire extinguisher, the detection module is screwed to the original pressure gauge position of the fire extinguisher through the fixing bolt, so as to fix the pressure detection module. Figure 2 As shown. The bolt sleeve is made of stainless steel to protect the fixing bolts. The pressure sensor adopts the GY-MS5837 30B high-precision gas pressure sensor module, which can collect the gas pressure value in real time and connect to the battery module. The power supply voltage only needs 3.0V. The communication module uses Bluetooth communication to transmit data with the box control module. The power module uses a 3.0V lithium-ion battery with a capacity of 1500mAh and a service life of up to 3 years. The battery slot can be opened on the back of the pressure detection module to facilitate the replacement of the battery later. The pressure monitoring shell is made of carbon fiber reinforced composite material with a cylindrical design, which not only enhances its rigidity but also facilitates installation.

[0033] In some embodiments, the control module determines whether the received pressure value is normal, and displays the pressure value on the display module, while generating an electronic maintenance record and outputting an alarm message when the pressure value is abnormal; the pressure value, alarm value, and electronic maintenance record are also transmitted to the remote management platform via LoRaWAN.

[0034] Each pressure detection module has a fixed code corresponding to the number of the fire extinguisher. The control module uploads the data detected by each pressure detection module to the remote management platform through wireless transmission. The operation and maintenance personnel remotely check whether the pressure of the fire extinguisher is normal through the remote management platform. If there is a problem with the pressure, an alarm will be prompted. By clicking the one-click generation button on the remote management platform, an electronic maintenance card can be generated or generated regularly. For the convenience of recording, the electronic maintenance card only shows whether the pressure of all fire extinguishers in the station is normal, but not the specific pressure value.

[0035] like Figure 1 and 3 As shown, an embodiment of the present invention further provides a substation fire extinguisher storage monitoring system, comprising a remote management platform 10 and a plurality of substation fire extinguisher storage monitoring devices 11 described in the above embodiments; The control module 7 of the substation fire extinguisher storage monitoring device 11 transmits the detected fire extinguisher pressure information to the remote management platform 10 through the information transmission module 9; The remote management platform 10 generates an electronic maintenance card for each set period of the fire extinguisher based on the pressure value, alarm value, and electronic maintenance record; the user views the electronic maintenance card information through the remote management platform or inputs query information into the control module through the display module to view the electronic maintenance record; the electronic maintenance card only displays whether the fire extinguisher pressure is normal.

[0036] The substation fire extinguisher storage monitoring system is a unit and algorithm step of each example described in combination with the embodiments disclosed in this article, which can be implemented by electronic hardware, computer software or a combination of the two. In order to clearly illustrate the interchangeability of hardware and software, the composition and steps of each example have been generally described in the above description according to function. Whether these functions are performed in hardware or software depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to be beyond the scope of the present invention.
