[0023] In summary, the beneficial effects of this utility model are as follows:
[0024] In this invention, through the protection device, when it is necessary to automatically monitor the natural gas pressure, natural gas enters the connecting pipe, and the high-pressure induction sensor and the low-pressure induction sensor measure the pressure in real time and transmit the signal to the controller. If the pressure exceeds the safe range, the controller will cut off the gas supply and shut down the machine for protection through the solenoid valve. Through the protection device, the problem of traditional thermal storage natural gas furnaces, although equipped with simple pressure monitoring instruments, can only realize the function of displaying pressure values and cannot automatically respond to and shut down the machine in case of abnormal pressure is solved.
[0025] In this invention, a fixing device is used to fix the hoisting rope to the auxiliary rod and the lifting rod when the natural gas furnace needs to be moved, so that the force is stable. After the hoisting machine applies force, the tension is transmitted to the base plate through the hoisting rope, auxiliary rod and lifting rod, and the base plate drives the furnace body to move, thus completing the safe hoisting. The fixing device solves the problem that traditional thermal storage natural gas furnaces generally do not have special and standardized hoisting components for hoisting needs, which significantly reduces hoisting efficiency.

[0031] Reference Figure 1 As shown, this utility model provides a technical solution: a dual-storage natural gas furnace, including a furnace body 1 and a controller 4. A protective device 2 is provided on one side of the furnace body 1, and a fixing device 3 is provided on the outer side of the furnace body 1.
[0032] The specific setup and function of its protective device 2 and fixing device 3 will be explained in detail below.
[0033] Reference Figure 2 and Figure 3As shown in this embodiment: the protection device 2 includes a connecting pipe 201, one end of which is fixedly connected to the furnace body 1. A connecting pipe 202 is fixedly connected to the arc surface of the connecting pipe 201. A high-pressure sensor 203 is fixedly connected to one end of the connecting pipe 202. A fixing pipe 204 is fixedly connected to the arc surface of the connecting pipe 201. A low-pressure sensor 205 is fixedly connected to one end of the fixing pipe 204. A solenoid valve 206 is fixedly connected to one end of the connecting pipe 201. An air inlet pipe 207 is fixedly connected to one end of the solenoid valve 206. This achieves the effect of the solenoid valve 206 cutting off the gas source, and the high-pressure sensor 203 and the low-pressure sensor 205 detecting the gas source pressure. A stabilizing frame 208 is fixedly connected to one side of the solenoid valve 206. This achieves the effect of fixing the stabilizing frame 208 to the solenoid valve 206. A support frame 209 is fixedly connected to one side of the stabilizing frame 208, and one side of the support frame 209 is fixedly connected to the furnace body 1. This achieves the effect of fixing the support frame 209 between the furnace body 1 and the support frame 209. A fixing seat 210 is fixedly connected to one side of the support frame 209. This achieves the effect of fixing the fixing seat 210 to the support frame 209. A stabilizing tube 211 is fixedly connected to one side of the fixing seat 210, and the inner side of the stabilizing tube 211 is fixedly connected to the connecting tube 201. This achieves the effect of fixing the stabilizing tube 211 to both the connecting tube 201 and the fixing seat 210.
[0034] Reference Figure 4 As shown in this embodiment: the fixing device 3 includes a base plate 31, the inner side of which is fixedly connected to the furnace body 1, and auxiliary rods 36 are fixedly connected to both sides of the base plate 31. This achieves the effect of the auxiliary rods 36 being fixed to the base plate 31, and the base plate 31 being fixed to the furnace body 1. Hanging rods 32 are fixedly connected to both sides of the base plate 31, and two fixing rings 35 are fixedly connected to the arc surface of the hanging rods 32. This achieves the effect of the fixing rings 35 being fixed to the hanging rods 32, and the hanging rods 32 being fixed to the base plate 31. Stabilizing plates 34 are fixedly connected to the arc surface of the fixing rings 35, and the two ends of the four stabilizing plates 34 are fixedly connected to the base plate 31. This achieves the effect of the fixing rings 35 being fixed to the stabilizing plates 34, and the stabilizing plates 34 being fixed to the base plate 31. Several anti-slip strips 33 are fixedly connected to the arc surface of the hanging rods 32, and the several anti-slip strips 33 are evenly distributed on the hanging rods 32. This achieves the effect of the anti-slip strips 33 increasing friction.
[0035] Working Principle: When automatic monitoring of natural gas pressure is required via protection device 2, connecting pipe 201 is installed at the gas inlet of furnace body 1. High-pressure sensor 203 (monitoring high pressure within connecting pipe 201), low-pressure sensor 205 (monitoring low pressure within connecting pipe 201), and solenoid valve 206 (controlling gas intake / outage) are then connected to controller 4, forming a pressure monitoring and control loop. During operation, natural gas is delivered to connecting pipe 201 via gas inlet pipe 207. High-pressure sensor 203 and low-pressure sensor 205 detect the pressure in real time and transmit signals to controller 4. If the detected pressure exceeds the safe range (high pressure or low pressure), controller 4 immediately... Solenoid valve 206 cuts off the gas supply, realizing automatic shutdown protection. When the pressure returns to normal, the system can automatically resume gas supply, ensuring safe and stable operation of the equipment. Since the support frame 209 is installed on the furnace body 1, the fixed seat 210 and the stabilizing frame 208 form a stable support. The stabilizing frame 208 supports the solenoid valve 206, and the fixed seat 210 drives the stabilizing pipe 211 to support the connecting pipe 201, preventing the solenoid valve 206 and the connecting pipe 201 from shifting position after installation. Through the protection device 2, the problem of traditional thermal storage natural gas furnaces, although equipped with simple pressure monitoring instruments, can only realize the function of displaying pressure values and cannot automatically respond to and shut down in case of abnormal pressure is solved.
[0036] With the fixing device 3, when the natural gas furnace needs to be moved, the operator first uses the hoist to anchor the fixed end of the hoisting rope to the auxiliary pole 36 and the lifting rod 32 respectively, so that the hoisting rope is in a stable stress state. Then, the hoisting machine applies tension, which is transmitted to the auxiliary pole 36 and the lifting rod 32 through the hoisting rope, and then jointly transmitted to the base plate 31. Finally, the base plate 31 acts as the main load-bearing body to drive the overall displacement of the furnace body 1, realizing safe hoisting and transportation. With the fixing device 3, the problem of traditional thermal storage natural gas furnaces generally not having special, standardized hoisting components for hoisting needs is solved, which significantly reduces hoisting efficiency.
