[0030] The following will refer to the appendix in the embodiments of this utility model. Figure 1 To be continued Figure 6 As shown, the technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0031] Example 1:

[0032] like Figures 1 to 3 As shown, this utility model provides a dual-source interlocking protection structure for an integrated electric-gas boiler co-steam supply system, which mainly includes an equipment box 1, a dual-source protection device, and a linkage control structure.

[0033] The key components include the device box 1, the dual-source protection device, and the linkage control structure. The dual-source protection device is composed of a gas protection part 2 and an electric protection part 3, both of which are stably arranged inside the device box 1. The gas protection part 2 is responsible for continuously monitoring the gas supply state and immediately executing the preset safety measures when any abnormal situation is detected. Similarly, the electric protection part 3 is responsible for real-time monitoring of the power supply state and promptly taking corresponding measures when abnormalities are found to ensure the safety and stability of the system operation.

[0034] The linkage control structure mainly includes a control circuit board 4 located above the device box 1, which mainly functions to achieve precise control and coordinated management of the gas protection part 2 and the electric protection part 3, ensuring efficient collaboration between the two during operation and further strengthening the overall safety performance of the system.

[0035] Embodiment Two:

[0036] In order to further clearly and completely describe the device box 1 in the above-mentioned embodiment one, and to stably fix the gas protection part 2 and the electric protection part 3 in the dual-source protection device, the utility model also provides embodiment two, which is described as follows: Figure 2 As shown in the figure, two ceramic plates 5 are arranged inside the device box 1, which are symmetrically arranged with the center axis of the device box 1 as the axis of symmetry and are fixedly connected to the inner wall of the device box 1. The two ceramic plates 5 effectively divide the inner cavity of the device box 1 into three parts, which are sequentially referred to as the gas device cavity 6, the isolation cavity 7, and the electric device cavity 8. It is to be noted that the gas device cavity 6 and the electric device cavity 8 are at least 8 centimeters apart.

[0037] In this way, the gas protection part 2 is arranged in the gas device cavity 6, and the electric protection part 3 is arranged in the electric device cavity 8.

[0038] At this point, the gas device cavity 6 and the electric device cavity 8 are effectively isolated by the isolation cavity 7 and the two ceramic plates 5. This layout not only ensures the independence of the gas device cavity 6 and the electric device cavity 8, but also significantly reduces the potential interference between gas and electricity, thereby improving the overall operational stability and safety of the system.

[0039] Embodiment Three:

[0040] In combination with embodiment two, the gas protection part 2 described in embodiment one is completely described, and embodiment three is provided, which is described as follows: Figure 2 and Figure 4As shown in the drawings, the gas protection part 2 mainly comprises a first connecting pipe 9, a second connecting pipe 10 and a third connecting pipe 11, which are arranged in the gas equipment cavity 6, and the first connecting pipe 9, the second connecting pipe 10 and the third connecting pipe 11 are arranged longitudinally along the direction of the gas equipment cavity 6.

[0041] It is to be noted that the first connecting pipe 9, the second connecting pipe 10 and the third connecting pipe 11 are spaced apart, the front part of the first connecting pipe 9 is connected to the front wall of the equipment box 1, the rear part of the third connecting pipe 11 is connected to the rear wall of the equipment box 1, and the rear end of the third connecting pipe 11 is connected to the boiler.

[0042] In order to make the gas protection part 2 operate normally, first, the front end of the first connecting pipe 9 penetrates through the front wall of the equipment box 1 and is fixedly connected with a ball valve 12, the ball valve 12 is of a fixed ball valve type, the front end of the ball valve 12 is connected with the external gas pipe, the first connecting pipe 9 and the second connecting pipe 10 are connected with each other through a three-way pipe 13, the three-way pipe 13 is provided with a pressure detector 14, the pressure detector 14 is of a piezoelectric pressure sensor type, the second connecting pipe 10 and the third connecting pipe 11 are connected through an electromagnetic valve 15, and the electromagnetic valve 15 is of a direct-acting type.

[0043] Therefore, the operation process of the third embodiment is as follows: the gas in the external gas pipe is continuously sent to the first connecting pipe 9 through the ball valve 12, and then flows to the second connecting pipe 10, the pressure detector 14 on the three-way pipe 13 is used for real-time monitoring, once the gas pressure is too low or too high, the electromagnetic valve 15 at the rear is closed to block the gas from flowing from the second connecting pipe 10 to the third connecting pipe 11, thereby playing a protection role.

[0044] Embodiment four:

[0045] In combination with the second embodiment, the power protection part 3 described in the first embodiment is further described in detail, and the fourth embodiment is provided, which is to be focused on. Figure 2 and Figure 5 As shown in the drawings, the power protection part 3 mainly comprises a solid-state relay 16 fixedly connected to the bottom wall of the power equipment cavity 8, the solid-state relay 16 is of a three-phase alternating current solid-state relay type, the input and output ports of the solid-state relay 16 are fixedly connected with an input cable one 17 and an output cable 18, respectively, an input cable two 19 is arranged in front of the input cable one 17, the input cable one 17 and the input cable two 19 are connected through a power detector, and the power detector is fixedly connected to the bottom wall of the power equipment cavity 8.

[0046] It is to be explained that the end of the output cable 18 away from the solid state relay 16 and the end of the input cable two 19 power detector all pass through the side wall of the equipment box 1 and are located outside the equipment box 1, wherein the end of the output cable 18 outside the equipment box 1 is connected with the boiler, and the end of the input cable two 19 outside the equipment box 1 is connected with the external power supply.

[0047] Further, the fourth embodiment uses the following process: the external power supply continuously inputs power into the power protection part 3 through the input cable two 19, and the voltage and current in the input cable two 19 are monitored in real time and continuously by the power detector. Once the voltage or current appears abnormal, the solid state relay 16 plays a role, and the connection between the input cable one 17 and the output cable 18 is disconnected, thereby playing a circuit protection role.

[0048] Embodiment five:

[0049] Further complete description of the linkage control structure described in embodiment one, provide embodiment five, please focus on viewing Figure 3 As shown, the linkage control structure further includes a protection box 20 fixedly connected to the top end of the equipment box 1, and the control circuit board 4 is fixedly connected to the inner wall of the protection box 20. In order to facilitate the electrical connection between other electrical equipment and the control circuit board 4, a plurality of through holes for threading are formed in the protection box 20.

[0050] Embodiment six:

[0051] The flashing alarm lamp and the buzzer are fixedly connected to the top end of the equipment box 1, which is used to remind people around when a fault occurs.

[0052] Finally, the pressure detector 14, the electromagnetic valve 15, the solid state relay 16, the power detector, the flashing alarm lamp and the buzzer, and the control circuit board 4 are electrically connected with the control circuit board 4.

[0053] Comprehensive embodiment one to embodiment six, combined with Figures 1 to 5 the schematic diagram, and Figure 6 The working principle of the utility model is shown in the following specific operation process of the utility model:

[0054] First, the connecting pipe three 11 is firmly connected with the gas inlet of the boiler, and at the same time, the output cable 18 is accurately connected with the electrical interface of the boiler. Then, the ball valve 12 is reliably connected with the external gas pipeline, and the input cable two 19 is stably connected with the power supply.

[0055] After the above connection is completed, the gas and the power are synchronously input into the device. In this process, the pressure detector 14 continuously monitors the gas pressure in the gas protection part 2, and the power detector monitors the voltage and the current in the power protection part 3 in real time. While being monitored in real time, the collected data is rapidly transmitted to the control circuit board 4.

[0056] Once any parameter of the power or the gas is monitored to be abnormal, or both parameters exceed the preset threshold value, the control circuit board 4 will immediately receive and process the data. Subsequently, the control circuit board 4 simultaneously issues control instructions to the electromagnetic valve 15 and the solid-state relay 16.

[0057] After receiving the instructions, the electromagnetic valve 15 rapidly acts to cut off the communication between the connecting pipe two 10 and the connecting pipe three 11, thereby preventing the gas from continuing to be input into the boiler. At the same time, the solid-state relay 16 also immediately responds to cut off the communication between the output cable 18 and the input cable one 17, thereby cutting off the power supply to ensure that the power cannot be input into the boiler.

[0058] Finally, the control circuit board 4 controls the buzzer and the flashing warning light to operate, which stimulates the surrounding people through visual and auditory dual sensory stimulation, reminds the surrounding people of the warning, and timely repairs.

[0059] Through the above series of coordinated actions, the double-source interlocking protection function is successfully realized, and the safety and stability of the boiler operation are effectively ensured.

[0060] In summary, the double-source interlocking protection structure of the integrated electric-gas boiler cooperative steam supply system provided by the utility model has the advantages that:

[0061] 1. By arranging the double-source protection device, the double monitoring and protection of the gas and the power supply are realized, the integration degree is high, and the safety performance of the electric-gas boiler is significantly improved.

[0062] 2. The ceramic plate 5 is arranged in the device box one 1 to effectively isolate the gas device cavity 6 and the power device cavity 8, potential interference between the gas and the power is reduced, and the operation stability and safety of the system are improved.

[0063] The utility model and its implementation modes are described above, and the description is not restrictive. The embodiment shown in the drawings is only one of the embodiments of the utility model, and the actual structure is not limited thereto. In summary, if a person skilled in the art is inspired thereby, without departing from the creative purpose of the utility model, similar structural modes and embodiments are not creatively designed, which should belong to the protection scope of the utility model.
