In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] See also Figure 1 - Figure 11, a fire extinguisher monitoring pressure gauge with a dual-mode positioning alarm device proposed by the present invention includes a case 1, an anti-blocking feeding mechanism 3, and a dial 6, and also includes a case cover 2 threadedly installed on the front of the case 1. An alarm 5 is embedded and installed on the front of the case cover 2. The dial 6 is installed inside the case 1 by bolts. On both sides of the front of the dial 6, a Beidou locator 601 and a Wi-Fi assisted locator 602 are respectively embedded and installed. A carbon film resistor 604 is embedded and installed at the center inside the dial 6, and a microprocessor 603 is embedded and installed below the carbon film resistor 604; an installation seat 102 is fixedly installed inside the case 1. A driving mechanism 4 is rotatably installed inside the installation seat 102, and the driving mechanism 4 extends to the outside of the case 1. An anti-blocking feeding mechanism 3 is threadedly installed on the back of the installation seat 102, and the anti-blocking feeding mechanism 3 extends to the back of the case 1. The driving mechanism 4 drives the anti-blocking feeding mechanism 3 to perform a drumming motion to automatically clean the fire extinguishing material of the anti-blocking feeding mechanism 3 and keep the anti-blocking feeding mechanism 3 stably conveying pressure;

[0029] Among them, the Beidou locator 601 and the Wi-Fi assisted locator 602 are electrically connected to the microprocessor 603 through wires. The position safety range value and the pressure safety range value are set through the microprocessor 603; the driving mechanism 4 drives the anti-blocking feeding mechanism 3 to perform a drumming motion. By performing a drumming motion through the anti-blocking feeding mechanism 3, the fire extinguisher material blocking the air inlet of the anti-blocking feeding mechanism 3 can be shaken off to ensure that the anti-blocking feeding mechanism 3 stably conveys pressure, thereby improving the accuracy of the pressure gauge;

[0030] The carbon film resistor 604 is electrically connected to the microprocessor 603 through a wire, and the resistance of the carbon film resistor 604 is affected by factors such as the length and cross-sectional area of the material. The electro-sensitive component 105 generates different resistance values at different positions of the carbon film resistor 604. Therefore, the microprocessor 603 detects the resistance value of the carbon film resistor 604 by detecting the contact position between the electro-sensitive component 105 and the carbon film resistor 604. The greater the resistance value of the carbon film resistor 604, the smaller the pointer 104 points to the pressure value. Thus, the pressure value of the fire extinguisher is judged, and the microprocessor 603 quickly judges that the pressure of the fire extinguisher is insufficient through the set pressure range;

[0031] When the microprocessor 603 determines that the pressure of the fire extinguisher is insufficient, the microprocessor 603 triggers the alarm 5, and the alarm 5 emits an audible and visual alarm and sends a wireless signal to the management personnel; at the same time, the Beidou locator 601 and the Wi-Fi auxiliary locator 602 locate the position of the fire extinguisher in real time, and the microprocessor 603 receives the positioning information of the Beidou locator 601 and the Wi-Fi auxiliary locator 602 and makes a judgment. When the microprocessor 603 determines that the fire extinguisher exceeds the position safety range value, the microprocessor 603 transmits the positioning information to the alarm 5, and the alarm 5 sends it to the management personnel through the wireless communication device 503; timely feedback and accurate positioning of the fire extinguisher when the pressure is insufficient or lost is achieved, which helps the management personnel to take measures quickly, such as replacing the fire extinguisher, repairing the leak or recovering the stolen equipment, thereby ensuring the integrity and availability of the fire-fighting equipment.

[0032] like Figure 8 - Figure 11 As shown, the anti-blocking feeding mechanism 3 is composed of a threaded disk 301, a threaded tube 302 and an anti-blocking component 303. The threaded disk 301 is fixedly installed on one end of the threaded tube 302, and the anti-blocking component 303 is fixedly installed on the other end of the threaded tube 302. The anti-blocking component 303 is composed of a sleeve 3031, a limit tube 3032, a hammer tube 3033, a toggle piece 3034, a diaphragm 3035, a spiral tube 3036 and a reset spring 3037. The limit tube 3032 is threadedly installed on one end of the sleeve 3031, the hammer tube 3033 is movably installed inside the sleeve 3031, the toggle pieces 3034 are embedded and installed on both sides of the inner wall of the hammer tube 3033, the diaphragm 3035 is installed on one end of the hammer tube 3033 through bolts, the spiral tube 3036 is rotatably installed inside the hammer tube 3033, and the reset spring 3037 is fixedly installed on the other end of the hammer tube 3033.

[0033] The driving mechanism 4 drives the spiral tube 3036 to rotate, and the rotating spiral tube 3036 drives the hammer tube 3033 to move through the toggle member 3034 to compress the reset spring 3037. When the spiral tube 3036 drives the toggle member 3034 to rotate to one end, the spiral tube 3036 releases the resistance to the toggle member 3034, so that the hammer tube 3033 moves quickly under the reset force of the compressed reset spring 3037, and the quickly moving hammer tube 3033 collides with the limit tube 3032. Thereby, the fire extinguishing material attached to the diaphragm 3035 can be beaten off, so as to achieve the purpose of automatically cleaning the diaphragm 3035, avoid blockage caused by the fire extinguishing material attached to the surface of the diaphragm 3035, ensure the air pressure passing rate of the diaphragm 3035, and use the diaphragm 3035 to isolate the fire extinguishing material in the fire extinguisher, avoid the fire extinguishing material from entering the spring tube 107 and affecting the expansion degree of the spring tube 107, ensure that the pressure gauge can measure the actual pressure of the substance to be measured, thereby ensuring the measurement accuracy and improving the precision of the pressure gauge.

[0034] like Figure 8 - Figure 10 As shown, the driving mechanism 4 is composed of a transmission rod 401, a worm 402, a worm wheel 403 and a transmission tube 404. The worm 402 is fixedly mounted on one end of the transmission rod 401, the top of the worm 402 is meshedly connected with the worm wheel 403, and the transmission tube 404 is mounted on one end of the worm wheel 403 through a connecting rod. One end of the transmission tube 404 extends to the inside of the sleeve 3031 and is fixedly connected to one end of the spiral tube 3036.

[0035] Among them, a knob is fixedly installed at one end of the transmission rod 401. The handheld knob drives the worm 402 to rotate through the transmission rod 401. The rotating worm 402 drives the transmission tube 404 to rotate through the meshing worm wheel 403. The rotating transmission tube 404 provides power for the anti-blocking component 303.

[0036] like Figure 1 - Figure 4 As shown, a sound alarm 501 and a light alarm 502 are respectively embedded and installed on both sides of the front of the alarm 5, and a wireless communicator 503 is embedded and installed in the center of the front of the alarm 5;

[0037] Among them, the alarm 5 sends out sound alarms, light alarms and wireless signals to management personnel through the sound alarm 501, light alarm 502 and wireless communicator 503, which helps management personnel to take measures quickly. The alarm 5 cooperates with the Beidou locator 601 and the Wi-Fi assisted locator 602 to achieve dual-mode positioning. The Beidou locator 601 and the Wi-Fi assisted locator 602 quickly determine the location of the fire extinguisher and send out sound and light alarms and status feedback through the alarm 5, thereby ensuring the integrity and availability of the fire-fighting equipment.

[0038] like Figure 3 , Figure 5 As shown, a battery 101 is fixedly installed below the mounting seat 102, a transmission mechanism 103 is movably installed on the front of the mounting seat 102, one side of the transmission mechanism 103 is transmission-connected to a spring tube 107 via a pull rod 106, a pointer 104 is fixedly installed on the front of the transmission mechanism 103, one end of the pointer 104 is embedded with an electric sensitive component 105, and the electric sensitive component 105 is in contact with and movably connected to the carbon film resistor 604;

[0039] Among them, the storage battery 101 is electrically connected to the microprocessor 603 through a wire, and the storage battery 101 provides power for the electrical equipment inside the device; and one end of the Bourdon tube 107 is connected to the threaded disc 301 through a pipeline, and the anti-blocking feeding mechanism 3 conveys the internal air pressure of the fire extinguisher to the Bourdon tube 107. The Bourdon tube 107 undergoes spiral expansion and contraction as the internal pressure of the fire extinguisher changes. The spirally expanding and contracting Bourdon tube 107 drives the transmission mechanism 103 through the pull rod 106, so as to drive the pointer 104 to deflect and rotate through the driven transmission mechanism 103. The deflected and rotating pointer 104 drives the electro-sensitive element 105 to move in contact on the surface of the carbon film resistor 604.

[0040] As Figure 1 - Figure 4 As shown, a double-layer glass 202 is embedded and installed inside the watch cover 2 through a sealing rubber ring 201, and the inner wall of the watch cover 2 is filled with heat-insulating liquid;

[0041] Among them, the sealing rubber ring 201 is used to enhance the sealing effect of the connection between the double-layer glass 202 and the watch cover 2, preventing water vapor from entering the inside of the watch cover 2 and the watch case 1, increasing the waterproof effect of the pressure gauge. At the same time, the inner wall of the watch case 1 is also filled with heat-insulating liquid. The heat-insulating liquid filled in the inner walls of the watch cover 2 and the watch case 1 can effectively isolate the heat transfer to the inside of the watch cover 2 and the watch case 1, avoiding the influence of the external temperature on the expansion degree of the Bourdon tube 107, ensuring that the pressure gauge can measure the actual pressure, thus guaranteeing the measurement accuracy and improving the precision of the pressure gauge.

[0042] As Figure 3 As shown, a scale table is embedded and installed above the front of the dial 6, and a wire passing hole is opened below the front of the dial 6;

[0043] Among them, the scale table consists of three sections of scales, which are successively represented as sufficient pressure, normal pressure, and insufficient pressure from left to right. When the pointer 104 rotates to different positions on the scale table, it correspondingly represents different internal pressure states of the fire extinguisher. The wire passing hole provides a position for the alarm 5 to pass the guiding wire to connect with the microprocessor 603, facilitating the electrical connection between the alarm 5 and the microprocessor 603 through a wire.

[0044] Working principle: The anti-blocking feeding mechanism 3 is driven to perform drumming movement through the driving mechanism 4 at a fixed time, so as to realize automatic cleaning of the fire extinguishing material of the anti-blocking feeding mechanism 3. Specifically, the worm 402 is driven to rotate through the transmission rod 401, and the rotating worm 402 drives the transmission tube 404 to rotate through the meshing worm wheel 403, and the rotating transmission tube 404 drives the spiral tube 3036 to rotate, and the rotating spiral tube 3036 drives the hammer tube 3033 to move through the toggle member 3034 to compress the reset spring 3037. When the spiral tube 3036 drives the toggle member 3034 to rotate to one end, the spiral tube 3036 releases the resistance to the toggle member 3034, so that the hammer tube 3033 moves quickly under the restoring force of the compressed restoring spring 3037, and the fast-moving hammer tube 3033 collides with the limiting tube 3032, so that the fire extinguishing material attached to the diaphragm 3035 can be knocked off, so as to achieve the purpose of automatically cleaning the diaphragm 3035, ensure the stable delivery pressure of the anti-blocking feeding mechanism 3, and thus improve the accuracy of the pressure gauge;

[0045] The anti-blocking feeding mechanism 3 transmits the internal air pressure of the fire extinguisher to the threaded disk 301 through the transmission tube 404, and the threaded disk 301 transmits the air pressure to the spring tube 107 through the pipeline. The spring tube 107 is spirally stretched as the internal pressure of the fire extinguisher changes. The spirally stretched spring tube 107 drives the transmission mechanism 103 through the pull rod 106, thereby driving the pointer 104 to deviate and rotate through the driven transmission mechanism 103. The deviated and rotated pointer 104 drives the electric sensitive part 105 to contact and move on the surface of the carbon film resistor 604;

[0046] The microprocessor 603 detects the resistance value of the carbon film resistor 604 by detecting the contact position between the electric sensitive part 105 and the carbon film resistor 604. The greater the resistance value of the carbon film resistor 604, the smaller the pressure value pointed by the pointer 104. The pressure value of the fire extinguisher is judged thereby. The microprocessor 603 quickly judges that the pressure of the fire extinguisher is insufficient through the set pressure range. When the microprocessor 603 judges that the pressure of the fire extinguisher is insufficient, the microprocessor 603 triggers the alarm 5, and the alarm 5 emits an audible and visual alarm and sends a wireless signal to the management personnel.

[0047] Meanwhile, the Beidou locator 601 and the Wi-Fi assisted locator 602 locate the position of the fire extinguisher in real time. The microprocessor 603 receives the positioning information from the Beidou locator 601 and the Wi-Fi assisted locator 602 and makes a judgment. When the microprocessor 603 determines that the fire extinguisher exceeds the position safety range value, the microprocessor 603 transmits the positioning information to the alarm 5. The alarm 5 emits an audible alarm, a visual alarm and sends a wireless signal to the management personnel through the sound alarm 501, the light alarm 502 and the wireless communicator 503. By cooperating with the Beidou locator 601 and the Wi-Fi assisted locator 602 through the alarm 5, dual-mode positioning is realized, thus effectively improving the use efficiency and safety of the fire extinguisher.

[0048] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
