Description

Technical Field

[0001] This utility model relates to the field of fire observation equipment technology, and in particular to a heat-insulated fire observation mirror. Background Technology

[0002] A heat-resistant fire-observation goggle is a tool specifically designed for observing high-temperature flames or incandescent objects, while effectively reducing heat transfer to the user and protecting the observer from heat-related injuries. This device is commonly used in industrial furnaces, boilers, glass manufacturing, metal smelting, and any situation requiring direct observation of combustion processes or high-temperature operations.

[0003] Although commercially available heat-resistant fire-viewing glasses can withstand high temperatures, their applicable temperature range is still limited, and their heat insulation effect is generally average. Furthermore, under extreme high temperatures, the lenses may soften or become damaged, affecting safety and observation accuracy.

[0004] Therefore, the above problems need to be solved. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a heat-insulating fire-viewing mirror to solve the problem that the heat insulation effect of fire-viewing mirrors in the prior art is generally poor.

[0006] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0007] An observation cylinder assembly includes an outer observation cylinder and an inner observation cylinder. The outer observation cylinder is sleeved on the inner observation cylinder, and the outer observation cylinder and the inner observation cylinder are spaced apart. A first cavity is provided in the space between the outer observation cylinder and the inner observation cylinder. An air inlet and an air outlet are provided on the side wall of the outer observation cylinder, which are connected to the first cavity. The air inlet is connected to external cooling gas to inject cooling gas into the first cavity, and the air outlet is connected to the outside.

[0008] An observation lens assembly is provided inside the observation cylinder assembly. The observation lens assembly includes a first observation lens and a second observation lens. The first observation lens and the second observation lens are respectively disposed on both axial sides of the inner observation cylinder.

[0009] To achieve the above technical solution, this application employs a double-layer observation tube and a double-layer lens structure. The duplex design effectively achieves heat insulation while providing excellent protection for the lenses. The first cavity serves as an air insulation layer, effectively blocking the transfer of external high temperatures to the interior, improving the overall heat insulation effect, and protecting the internal structure and the user. Furthermore, an external cooling device is introduced to actively cool the first cavity. The continuous circulation of cold air effectively removes heat, further enhancing the heat insulation performance and ensuring that the internal structure and lenses are kept in a suitable temperature environment.

[0010] In one embodiment of the present invention, the observation inner cylinder includes an inner cylinder head, an inner cylinder tail, and an inner cylinder cavity; the inner cylinder head and the inner cylinder tail are located at both axial ends of the inner cylinder cavity; the observation outer cylinder includes an outer cylinder head, an outer cylinder tail, and an outer cylinder cavity; the outer cylinder head and the outer cylinder tail are located at both axial ends of the outer cylinder cavity.

[0011] By implementing the above technical solution, this application has a clear structure, well-defined functional areas, and is easy to maintain, while also improving observation accuracy and adaptability.

[0012] In one embodiment of the present invention, the first observation lens is disposed at the head of the inner cylinder, the second observation lens is disposed at the tail of the inner cylinder, and a second cavity for heat insulation is formed between the first observation lens and the second observation lens.

[0013] To achieve the above technical solution, the second cavity of this application serves as an air isolation layer, which can effectively block heat from being directly conducted through the lens, further improving the overall heat insulation performance and protecting the observer and internal structure from the effects of high temperatures.

[0014] In one embodiment of the present invention, the inner cylinder head extends beyond the outer cylinder head, and the first observation lens is located at the portion of the inner cylinder head extending beyond the outer cylinder head.

[0015] To achieve the above technical solution, the inner cylinder head of this application is located outside the outer cylinder head, which effectively avoids the first observation lens being affected by high-temperature flue gas and facilitates the observation of the combustion situation inside the boiler.

[0016] In one embodiment of the present invention, the axial length of the inner cylinder tail is smaller than the axial length of the outer cylinder tail, and a third cavity for heat insulation is provided at the outer cylinder tail. One end of the third cavity is open, and the second observation lens is located at the other end of the third cavity.

[0017] By implementing the above technical solution, the third cavity structure of this application can prevent high temperature from being directly transmitted to the connection part of the fire-observing mirror, and effectively prevent the first observation lens from being affected by high temperature smoke, thereby improving structural stability and safety.

[0018] In one embodiment of the present invention, the outer layers of the first observation lens and the second observation lens are provided with ultraviolet light-transmitting coatings.

[0019] To achieve the above technical solution, this application sets up a light-transmitting lens, so that the observation method is not limited to naked-eye observation, but can also monitor the flame in real time through a professional ultraviolet light tube.

[0020] As described above, the heat-insulating fire-observing mirror of this utility model has the following beneficial effects:

[0021] 1. The present application proposes a heat-insulating fire-observing mirror, which adopts a double-layer observation tube structure, with an inner observation tube and an outer observation tube respectively. The duplex design effectively achieves the heat insulation function, while providing good protection for the lens. The double-layer lens structure further enhances the heat insulation effect, significantly reduces the impact of high temperature on the temperature of the observation lens on the observer's side, and improves the safety and comfort of use.

[0022] 2. The heat-insulating fire-viewing mirror proposed in this application involves a first cavity, a second cavity, and a third cavity that can serve as an air insulation layer space. By introducing an external cold air device, the first cavity can be actively cooled. The continuous input of cold air can effectively remove heat, effectively block the transfer of external high temperature to the interior, improve the overall heat insulation effect, and protect the internal structure and the user.

[0023] 3. The heat-insulated fire observation mirror proposed in this application has the inner observation cylinder and the outer observation cylinder installed coaxially with a misalignment, which effectively avoids the first observation lens and the second observation lens being affected by high-temperature flue gas and facilitates the observation of the combustion situation inside the boiler.

Detailed Implementation

[0028] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] Please see Figure 1 This utility model provides a heat-insulating fire-observing mirror, the structure of which includes: an observation tube assembly 1 and an observation lens assembly 2, with the observation lens assembly 2 disposed inside the observation tube assembly 1.

[0030] For further details, please refer to Figure 2 The observation cylinder assembly 1 includes an outer observation cylinder 101 and an inner observation cylinder 102, with the outer observation cylinder 101 sleeved on the inner observation cylinder 102.

[0031] For further details, please refer to Figure 3 The observation lens group 2 includes a first observation lens 201 and a second observation lens 202; the first observation lens 201 and the second observation lens 202 are respectively disposed on both sides of the axial direction of the observation inner cylinder 102.

[0032] Furthermore, observe the intermittent fit between the outer cylinder 101 and the inner cylinder 102.

[0033] Furthermore, a first cavity 3 is provided within the space between the outer observation cylinder 101 and the inner observation cylinder 102. An air inlet 6 and an air outlet 7, connecting to the first cavity 3, are provided on the side wall of the outer observation cylinder 101. The air inlet 6 connects to external cooling gas to inject cooling gas into the first cavity 3, and the air outlet 7 connects to the outside. This double-layer observation cylinder and double-layer lens structure effectively achieves heat insulation through its duplex design, while also providing good protection for the observation lens assembly 2. The first cavity 3 serves as an air insulation layer, effectively blocking the transfer of external high temperatures to the interior, improving the overall heat insulation effect, and protecting the internal structure and the user. An external cooling air device is also introduced to actively cool the first cavity 3. The continuous circulation of cold air effectively removes heat, further enhancing the heat insulation performance and ensuring that the internal structure and lenses are in a suitable temperature environment.

[0034] Furthermore, the inner cylinder 102 includes an inner cylinder head 1021, an inner cylinder tail 1022, and an inner cylinder cavity; the inner cylinder head 1021 and the inner cylinder tail 1022 are located at both axial ends of the inner cylinder cavity; the outer cylinder 101 includes an outer cylinder head 1011, an outer cylinder tail 1012, and an outer cylinder cavity; the outer cylinder head 1011 and the outer cylinder tail 1012 are located at both axial ends of the outer cylinder cavity.

[0035] Furthermore, a first observation lens 201 is located at the head 1021 of the inner cylinder, and a second observation lens 202 is located at the tail 1022 of the inner cylinder. A second cavity 4 for heat insulation is formed between the first observation lens 201 and the second observation lens 202. The distance between the first observation lens 201 and the second observation lens 202 can be adaptively set according to actual needs. The second cavity 4, as an air isolation layer, can effectively block heat from being directly conducted through the lenses, further improving the overall heat insulation performance and protecting the observer and the internal structure from high temperatures.

[0036] Furthermore, the inner cylinder head 1021 extends beyond the outer cylinder head 1011, and the first observation lens 201 is located on the portion of the inner cylinder head 1021 extending beyond the outer cylinder head 1011. The inner cylinder head 1021 is located outside the outer cylinder head 1011, effectively preventing the first observation lens 201 from being affected by high-temperature flue gas, thus facilitating the observation of the combustion situation inside the boiler.

[0037] Furthermore, the axial length of the inner cylinder tail 1022 is smaller than that of the outer cylinder tail 1012, and its dimensions can be adaptively adjusted according to actual needs. A third cavity 5 for heat insulation is provided at the outer cylinder tail 1012. One end of the third cavity 5 is open, and the second observation lens 202 is located at the other end of the third cavity 5. This third cavity 5 structure prevents high temperatures from being directly transmitted to the connection points of the fire-observing lens and effectively prevents the first observation lens 201 from being affected by high-temperature smoke, thus improving structural stability and safety.

[0038] Furthermore, the outer layer of the first observation lens 201 and the second observation lens 202 is provided with an ultraviolet light-transmitting coating.

[0039] Furthermore, in routine operations, operators can visually observe the flame status through the observation lenses; they can also use ultraviolet light tubes for auxiliary monitoring. Utilizing the light transmission characteristics of specially designed first observation lens 201 and second observation lens 202, which have excellent ultraviolet transmittance, professional ultraviolet light tubes can more accurately monitor the flame. The ultraviolet light tubes can detect specific ultraviolet radiation in the flame and identify the flame's combustion efficiency, chemical composition, or abnormal conditions.

[0040] Furthermore, a method of using a heat-insulated fire-observing mirror includes:

[0041] Step S1: Prefabricate observation tube assembly 1 and observation lens assembly 2 according to actual needs;

[0042] Step S2: Install the first observation lens 201 and the second observation lens 202 on the head 1021 and tail 1022 of the inner cylinder, respectively;

[0043] Step S3: Fit the outer observation cylinder 101 onto the inner observation cylinder 102;

[0044] Step S4: Connect a pipe at the air inlet 6 to inject cooling gas; install a pipe at the air outlet 7 to discharge heated gas.

[0045] Step S5: Monitor the flame with the naked eye or with the aid of an ultraviolet light tube using a flame-viewing microscope, and record the changes in the flame status regularly. Adjust the combustion parameters or take corresponding measures as needed.

[0046] Furthermore, it is necessary to clean the surface of the observation lens group 2 regularly, using special tools to remove dust and contaminants to avoid damaging the lens surface, and to check the sealing of all connection parts.

[0047] The technical advantages of this embodiment are as follows: This design, through the use of a double-layer observation tube structure, a multi-cavity heat insulation system, and a combination of double-layer transparent observation lenses, along with the introduction of cold air cooling, achieves efficient isolation and safe observation of high-temperature flame environments. This not only significantly improves the heat insulation performance and observation clarity of the fire-observation mirror system but also enhances the safety of the equipment. Furthermore, it supports both visual observation and professional instrument monitoring modes, expanding its application in industrial combustion control and monitoring scenarios.
