Description

Technical Field

[0001] The embodiments of the utility model relate to the technical field of detection, and in particular to a fault detection device for a narrow space. Background Art

[0002] When inspecting equipment in a computer room, personnel often encounter situations where the cramped space prevents access and accurate observation of equipment status, resulting in low inspection efficiency and poor results, which increases risk points. For example, a precision air-cooling air conditioning machine room houses numerous devices, including compressors, expansion valves, evaporators, dry filters, humidifiers, and indoor copper pipes, making the space compact. When equipment failures occur, the space available for maintenance is limited. Furthermore, the power distribution cabinets in the computer room are typically installed against the wall, and cables are laid under the floor or in cable trenches. With so many cables, cable failures often require drilling under the floor or removing other equipment for inspection, which is time-consuming and labor-intensive. Alternatively, maintenance personnel cannot reach the fault point, making it difficult to determine the fault's severity. Even after inspections are completed, inspection results cannot be immediately confirmed. Instead, the equipment is typically restarted to see if it operates normally. If it still does not operate normally, it is determined that the inspection is incomplete, and this cycle repeats. This results in low inspection efficiency and poor results, and increases the risk of prolonged equipment failures. Utility Model Content

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0020] Figure 1 This is a schematic diagram of the structure of a fault detection device for a narrow space provided by an embodiment of the utility model. Figure 2 This is a schematic diagram of the structure of another narrow space fault detection device provided by the embodiment of the utility model. Figure 1 and Figure 2 As shown, the fault detection device for a narrow space includes a fill light 110, a multi-faceted folding mirror 120 and a shell 130; the fill light 110 and the multi-faceted folding mirror 120 are arranged on the same outer surface of the shell 130, and the multi-faceted folding mirror 120 includes multiple mirror surfaces 121, and the angles between adjacent mirror surfaces 121 are adjustable.

[0021] Specifically, the narrow space can be a machine room area. In the narrow space, there are many devices, and the space for maintenance is very narrow. This makes it impossible for maintenance personnel to enter for maintenance, or after entering the narrow space, they cannot reach the fault point and cannot perform maintenance. Moreover, the light in the narrow space is very dim, which seriously affects the vision of maintenance personnel, further increasing the difficulty of maintenance. The fill light 110 is provided on the outer surface of the shell 130. When troubleshooting equipment in a narrow space, the fill light 110 can fill in the light at the location with poor light in the narrow space. For example, Figure 1 and Figure 2As shown, the fault detection device for a narrow space may include four fill lights 110, which are respectively arranged at the four top corners of the outer surface of the shell 130 to ensure the fill light effect at the position with poor lighting in the narrow space. At the same time, a multi-faceted folding mirror 120 is provided on the outer surface of the shell 130. The angles between the multiple mirror surfaces 121 of the multi-faceted folding mirror 120 are adjustable, so that the multi-faceted folding mirror 120 can be folded or unfolded. When the fill light 110 is illuminated, the folding and unfolding states of the multi-faceted folding mirror 120 can be adjusted according to the maintenance requirements in the narrow space, so that the multi-faceted folding mirror 120 can adjust the optical path of the light emitted by the fill light 110, and irradiate the adjusted light at multiple angles to the position that needs to be repaired, so that the fill light 110 and the multi-faceted folding mirror 120 can be used to perform all-round fill light on the position with poor lighting in the narrow space, thereby improving the detection effect of the maintenance position. Moreover, the fault detection device for a narrow space has a simple structure, which makes the size of the fault detection device for a narrow space very small. During the troubleshooting process in a narrow space, the fault detection device for the narrow space can be placed at any location according to the maintenance requirements, which can further ensure the detection effect of the maintenance location, ensure the accuracy of the maintenance personnel's fault judgment and the accuracy of the maintenance, thereby improving the maintenance effect and efficiency of the equipment in the narrow space. In addition, the fill light 110 and the multi-faceted folding mirror 120 are arranged on the same outer surface of the shell 130, which can ensure that the multi-faceted folding mirror 120 can adjust more light when the fill light 110 is illuminated, thereby improving the utilization rate of light. The material of the multi-faceted folding mirror 120 can be a high-temperature resistant material to avoid damage to the multi-faceted folding mirror 120 caused by excessive temperature.

[0022] For example, in the machine room of a precision air conditioner, when a leak occurs in an indoor copper pipe, the location and status of the copper pipe leak can be fully detected using the fill light 110 and the multi-faceted folding mirror 120. Maintenance personnel can inspect and weld the copper pipe while clearly observing the leakage status of the copper pipe in real time. They can intuitively judge whether the copper pipe maintenance has been completed and quickly and accurately solve the problem. When adding oil to the compressor against the wall, the fill light 110 and the multi-faceted folding mirror 120 can also be used to clearly and intuitively observe the liquid level of the oil mirror to avoid the problem of over- or under-filling of oil, thereby reducing the risk of failure of the precision air conditioner compressor.

[0023] The technical solution of this embodiment is to provide a fill light and a multi-faceted folding mirror on the housing of the fault detection device for a narrow space. In the narrow space where there is insufficient light, the fill light and the multi-faceted folding mirror can be used to fill light at the maintenance position at multiple angles, thereby improving the detection effect of the maintenance position. Moreover, the structure of the fault detection device for a narrow space is simple, so that the volume of the fault detection device for a narrow space is very small. During the fault repair process in a narrow space, the fault detection device for a narrow space can be placed at any position according to the repair requirements, which can further ensure the detection effect of the maintenance position, ensure the accuracy of the fault judgment and the accuracy of the repair by the maintenance personnel, and thus improve the repair effect and efficiency of the equipment in the narrow space.

[0024] Continue to refer Figure 2 The multi-faceted folding mirror 120 includes a first mirror surface 121A, a second mirror surface 121B, a third mirror surface 121C and a fourth mirror surface 121D connected in sequence. The second mirror surface 121B and the third mirror surface 121C are arranged on the outer surface of the shell 130. The angle of the first mirror surface 121A and the second mirror surface 121B can be adjusted in the range of 0-180°, and the angle of the fourth mirror surface 121D and the third mirror surface 121C can be adjusted in the range of 0-180°.

[0025] Specifically, the second mirror surface 121B and the third mirror surface 121C are disposed on the outer surface of the housing 130, connecting the multi-faceted folding mirror 120 to the housing 130. This ensures that the mirror surface of the multi-faceted folding mirror 120 parallel to the surface of the housing 130 is relatively large, thereby ensuring the intensity of the light from the fill light 110 radiating forward after passing through the multi-faceted folding mirror 120. The angles of the first mirror surface 121A and the second mirror surface 121B can be adjusted, allowing the first mirror surface 121A and the second mirror surface 121B to switch between a folded state and a flattened state. This allows the angle of the light emitted by the first mirror surface 121A to be adjusted, allowing the light to be directed at the desired inspection location from multiple angles. Similarly, the angles of the fourth mirror surface 121D and the third mirror surface 121C can be adjusted, allowing the fourth mirror surface 121D and the third mirror surface 121C to switch between a folded state and a flattened state. This allows the angle of the light emitted by the fourth mirror surface 121D to be adjusted, allowing the light to be directed at the desired inspection location from multiple angles.

[0026] Continue to refer Figure 1 The fault detection device for a narrow space further includes a suction cup 140 , which is connected to the shell 130 . The suction cup 140 is used to be adsorbed on a fixed carrier to fix the shell 130 .

[0027] Specifically, the suction cup 140 is connected to the housing 130. When the suction cup 140 is attached to a fixed carrier, the housing 130 can be fixed by the suction cup 140, thereby fixing the fault detection device in a narrow space, making it easier for maintenance personnel to perform maintenance operations. For example, the suction cup 140 can be a magnetic suction cup, in which case the fixed carrier can be the metal housing of the device. When the suction cup 140 is attached to the metal housing of the device, the fault detection device in a narrow space can be fixed to the metal housing of the device, making it easier for maintenance personnel to perform maintenance operations with both hands.

[0028] Continue to refer Figure 1 The fault detection device for a narrow space further includes a flexible and shaped connecting line 150 , and the suction cup 140 is connected to the housing 130 via the flexible and shaped connecting line 150 .

[0029] Specifically, the flexible shaped connecting wire 150 is bendable and has a supporting force. When a fault is detected in a narrow space by the fault detection device, the flexible shaped connecting wire 150 can be bent according to the maintenance location, and the housing 130 can be moved to a narrow space that is difficult for maintenance personnel to enter. Thus, the fault detection device in a narrow space can be placed at any location according to maintenance needs, which can further ensure the detection effect of the maintenance location, ensure the accuracy of the maintenance personnel's fault diagnosis and the accuracy of the maintenance, and thus improve the maintenance effect and efficiency of the equipment in the narrow space. Exemplarily, the material of the flexible shaped connecting wire 150 is copper, aluminum alloy, steel or titanium alloy.

[0030] Continue to refer Figure 1 The fault detection device for a narrow space further includes a power supply 160 , which is disposed in the housing 130 . The power supply 160 is connected to the fill light 110 for supplying power to the fill light 110 .

[0031] Specifically, the power supply 160 is connected to the fill light 110 and can supply power to the fill light 110 so that the fill light 110 can emit light.

[0032] Figure 3 This is a schematic diagram of the structure of another narrow space fault detection device provided by the embodiment of the utility model. Figure 3 As shown, reference Figures 1 to 3 The housing 130 includes a body 131 and a cover 132 . The cover 132 covers a side surface of the body 131 . The fill light 110 and the multi-faceted folding mirror 120 are arranged on a surface of the cover 132 away from the body 131 .

[0033] Specifically, Figures 1 to 3 The body 131 is exemplarily shown as a rectangular parallelepiped. The cover 132 is provided on the side surface of the body 131, for example Figures 1 to 3The front of the cover 132 is positioned so that both the fill light 110 and the multi-faceted folding mirror 120 are positioned on the front of the fault detection device in a narrow space, facilitating the fill light application to the inspection location. Furthermore, the fill light 110 and the multi-faceted folding mirror 120 are positioned on the outer surface of the cover 132, ensuring optimal light output from the fill light 110 and the multi-faceted folding mirror 120.

[0034] Continue to refer Figure 3 The fault detection device for a narrow space also includes an infrared detector 170. The infrared detector 170 is arranged on the outer surface of the fuselage 131. When the cover 132 covers the surface of the fuselage 131, the infrared detector 170 is located between the fuselage 131 and the cover 132. The infrared detector 170 is used to detect the ambient temperature.

[0035] Specifically, the infrared detector 170 can detect the ambient temperature in a narrow space. The infrared detector 170 is arranged on the front of the fuselage 131. When the lid 132 is closed, the fill light 110 and the multi-faceted folding mirror 120 are arranged on the outer surface of the fault detection device for a narrow space, so that the fault detection device for a narrow space uses the fill light 110 and the multi-faceted folding mirror 120 to perform fault detection on the equipment in the narrow space. When the lid 132 is opened, the infrared detector 170 is located on the outer surface of the fault detection device for a narrow space, and the infrared detector 170 can detect the ambient temperature in real time. The fault detection device for a narrow space can be moved to the position required for maintenance according to maintenance requirements, thereby realizing temperature detection of equipment in a narrow space, judging whether the equipment has local overheating according to the temperature, and determining the location of local overheating according to the location of the temperature change, which significantly improves the maintenance efficiency and accuracy of equipment in a narrow space. For example, in a precision air conditioning room, infrared detector 170 can be used to detect cable temperature. Using flexible, shaped connecting wire 150, the fault detection device can be moved from a confined space to a location inaccessible to maintenance personnel, such as underground or in a cable trench. This allows infrared detector 170 to accurately detect cable temperature and, based on temperature fluctuations, locate overheating areas, thus avoiding the risk of power failures caused by cable overheating. Furthermore, power supply 160 can be connected to infrared detector 170 to power it.

[0036] Continue to refer Figure 3 The fault detection device for a narrow space further includes a display 180 , which is connected to the infrared detector 170 , and is used to display the temperature signal output by the infrared detector 170 .

[0037] Specifically, the display 180 is connected to the infrared detector 170 and can display the temperature output by the infrared detector 170, so that maintenance personnel can observe the temperature of the equipment intuitively. Figure 3As shown, the display 180 can display the current temperature of the device as XX.X°C according to the temperature signal, and the current temperature can be accurate to one decimal place. In addition, the power supply 160 can also be connected to the display 180 to supply power to the display 180.

[0038] Continue to refer Figure 3 The display 180 is arranged on the surface of the cover 132 close to the body 131. The display 180 can be exposed when the cover 132 is opened, so that when the infrared detector 170 detects the temperature of the device, the maintenance personnel can intuitively observe the temperature of the device through the display 180, which is convenient for the maintenance personnel to judge the status of the device according to the temperature.
