Description

Technical Field

[0001] This invention belongs to the field of infrared thermal imager technology, and more specifically, relates to a heat dissipation and protective housing for infrared thermal imagers. Background Technology

[0002] An infrared thermal imager is a detection device based on infrared thermal imaging technology. It receives the infrared radiation from an object and, through signal processing and photoelectric conversion, transforms the temperature distribution of the target object into a visualized image. During the operation of power equipment, most faults are accompanied by abnormal heating. Infrared thermal imagers can help maintenance personnel identify potential overheating hazards in equipment in a timely manner, thereby preventing faults and improving the reliability and safety of power grid operation.

[0003] During periods of sustained high temperatures and peak electricity load in summer, infrared thermal imagers often need to operate continuously outdoors for 2 to 4 hours or more to capture temperature changes in power equipment. To ensure the continuous and reliable operation of infrared thermal imagers under high temperatures and sunlight, inspection personnel usually install heat dissipation covers on the outside of the imagers to enhance heat dissipation and maintain normal operation. However, existing heat dissipation covers are generally bulky, making them inconvenient to carry or use, and failing to meet the current practical needs of power inspection personnel for lightweight and portable equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a heat dissipation and protective housing for infrared thermal imagers, aiming to solve the problem that existing heat dissipation covers are bulky and inconvenient to carry.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a heat dissipation and protective housing for an infrared thermal imager, comprising: Upper shell; The lower housing is disposed opposite to the upper housing and is connected by two symmetrically arranged folding plates; A cooling fan is hinged to the lower housing and has an upright state and a folded state relative to the lower housing. When the folding plate is in the unfolded state and the cooling fan is in the upright state, the upper housing, the lower housing, and the two folding plates form a first space for accommodating the infrared thermal imager, and the air outlet of the cooling fan faces the infrared thermal imager; when the folding plate is in the folded state and the cooling fan is in the collapsed state, the upper housing, the lower housing, and the two folding plates form a second space, and the cooling fan is accommodated in the second space.

[0006] In one possible implementation, a flip plate is rotatably disposed on the lower housing, and a power supply for supplying power to the cooling fan is disposed on the flip plate; When the cooling fan is in the upright position, the flip plate can be rotated so that the power supply is outside the first space, so that the power supply avoids the infrared thermal imager; when the cooling fan is in the folded position, the flip plate can be rotated so that the power supply is housed inside the second space.

[0007] In one possible implementation, a mounting plate is hinged to the lower housing, and the cooling fan is mounted on the mounting plate; a positioning component is provided at the end of the mounting plate opposite to the hinge axis. Both the upper housing and the flip plate are fixedly provided with connecting blocks suitable for engaging with the positioning component. When the cooling fan is in the upright position, the positioning component engages with the connecting block on the upper housing; when the cooling fan is in the collapsed position and the flip plate rotates to accommodate the power supply inside the second space, the positioning component engages with the connecting block on the flip plate.

[0008] In one possible implementation, the positioning component includes: The positioning post is slidably mounted on the mounting plate; A positioning spring, with its two ends fixed to the mounting plate and the positioning post respectively, is used to push the positioning post out of the mounting plate; Each of the connecting blocks has a slot suitable for engaging with the positioning post.

[0009] In one possible implementation, each of the slots is an arc-shaped slot, and the positioning post has an arc-shaped end adapted to engage with the arc-shaped slot.

[0010] In one possible implementation, the rotation axis of the flip plate is perpendicular to the rotation axis of the mounting plate.

[0011] In one possible implementation, a telescopic rod is connected between the upper housing and the lower housing, and the telescopic rod has a locking element for locking the telescopic length; The telescopic rod has a first length and a second length; When the folding panel is in the unfolded state, the telescopic rod is locked at the first length to keep the folding panel in the unfolded state. When the folded panel is in the folded state, the telescopic rod is locked at the second length to keep the folded panel in the folded state.

[0012] In one possible implementation, the telescopic rod includes: The inner tube is hinged to the upper shell; The outer tube is slidably sleeved on the inner tube and hinged to the lower shell.

[0013] In one possible implementation, the locking element includes: The sliding sleeve is fixedly mounted on the inner tube; The locking pin is slidably disposed within the sliding sleeve, and the sliding direction is along the radial direction of the inner tube; A locking spring, with its two ends fixed to the sliding sleeve and the locking pin respectively, is used to push the locking pin out of the sliding sleeve; The outer tube has a first locking hole and a second locking hole; when the locking pin is inserted into the first locking hole, the telescopic rod is at the first length; when the locking pin is inserted into the second locking hole, the telescopic rod is at the second length.

[0014] In one possible implementation, the folding plate includes: The first plate is hinged to the upper housing. The second plate is hinged at both ends to the first plate and the lower shell, respectively.

[0015] The present invention provides a heat dissipation and protective housing for an infrared thermal imager. Compared with the prior art, the advantages are as follows: the upper and lower housings are connected by symmetrically arranged folding plates to form a main frame. When the folding plates are in the unfolded state and the cooling fan is upright relative to the lower housing, the upper housing, lower housing, and two folding plates together form a first space for accommodating the infrared thermal imager. At this time, the exhaust end of the cooling fan is directly facing the infrared thermal imager, which can effectively enhance airflow circulation, improve heat dissipation efficiency, and ensure that the equipment continues to work stably in high-temperature environments.

[0016] When the equipment needs to be stored and carried, the folding plate can be folded and retracted, and the cooling fan can be hinged and rotated to a folded state. At this time, the upper shell, lower shell and folding plate form a second space with a significantly reduced volume, and the cooling fan is completely housed inside it, which greatly improves the compactness and portability of the overall structure and meets the actual needs of power inspection personnel for lightweight and convenient carrying of equipment.

[0027] To make the technical problems, technical solutions, and beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0028] It should be further noted that the accompanying drawings and embodiments of the present invention mainly describe the concept of the present invention. Based on this concept, some specific forms and arrangements of connection relationships, positional relationships, power mechanisms, power supply systems, hydraulic systems and control systems may not be fully described. However, under the premise that those skilled in the art understand the concept of the present invention, they can implement the above-mentioned specific forms and arrangements in a well-known manner.

[0029] For ease of description, spatial relative terms such as “above”, “on top of”, “on the upper surface of”, “above”, etc., can be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure.

[0030] It should be understood that spatial relative terms are intended to encompass different orientations of a device in use or operation, in addition to those described in the figures. For example, if a device in the figures is inverted, a device described as "above" or "on top of" other devices or structures will subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below". The device may also be positioned in other different ways, and the spatial relative descriptions used herein will be interpreted accordingly.

[0031] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, and "several" means one or more, unless otherwise explicitly specified.

[0032] To facilitate understanding, we will now introduce infrared thermal imagers and their application scenarios.

[0033] An infrared thermal imager is a detection device based on infrared thermal imaging technology. It receives the infrared radiation from an object and, through signal processing and photoelectric conversion, transforms the temperature distribution of the target object into a visualized image. During the operation of power equipment, most faults are accompanied by abnormal heating. Infrared thermal imagers can help maintenance personnel identify potential overheating hazards in equipment in a timely manner, thereby preventing faults and improving the reliability and safety of power grid operation.

[0034] During periods of sustained high temperatures and peak electricity load in summer, infrared thermal imagers often need to operate continuously outdoors for 2 to 4 hours or more to capture temperature changes in electrical equipment. To ensure the continuous and reliable operation of infrared thermal imagers under high temperatures and sunlight, inspection personnel usually install heat dissipation covers on the outside of the infrared thermal imagers to enhance heat dissipation and maintain normal operation.

[0035] However, existing heat sink covers are generally bulky, making them inconvenient to carry or use, and failing to meet the practical needs of current power inspection personnel for lightweight and portable equipment. This application provides a heat dissipation and protective housing for an infrared thermal imager, solving the problem of the large size and inconvenience of carrying existing infrared thermal imager heat sink covers.

[0036] Please see Figures 1 to 8 The present invention will now describe a heat dissipation and protective housing for an infrared thermal imager.

[0037] Please see Figure 1 , Figure 2 and Figure 3 An infrared thermal imager heat dissipation and protective housing includes an upper housing 1, a lower housing 2, and a cooling fan 41. The lower housing 2 is positioned opposite the upper housing 1 and connected by two symmetrically arranged folding plates 3. The cooling fan 41 is hinged to the lower housing 2 and has both an upright and a folded-down position relative to the lower housing 2.

[0038] When the folding plate 3 is in the unfolded state and the cooling fan 41 is in the upright state, the upper housing 1, the lower housing 2, and the two folding plates 3 form a first space 61 for accommodating the infrared thermal imager 5, and the exhaust end of the cooling fan 41 faces the infrared thermal imager 5. When the folding plate 3 is in the folded state and the cooling fan 41 is in the collapsed state, the upper housing 1, the lower housing 2, and the two folding plates 3 form a second space 62, and the cooling fan 41 is accommodated in the second space 62.

[0039] It should be noted that a connecting seat for connecting to a tripod can be provided on the lower surface of the lower housing 2 to facilitate the use of a tripod to support the infrared thermal imager 5.

[0040] When working, if the infrared thermal imager 5 needs to be used, first unfold the two symmetrically arranged folding plates 3 from the folded state, so that the upper shell 1 and the lower shell 2, which are hinged to both ends of the folding plates 3, are far apart from each other, and finally form a first space 61 for accommodating the infrared thermal imager 5. At this time, the cooling fan 41, which is hinged to the lower shell 2, rotates around the hinge axis to the upright state, so that its air outlet can face the infrared thermal imager 5 in the first space 61, thereby blowing air to cool the infrared thermal imager 5, avoiding the infrared thermal imager 5 from malfunctioning due to overheating in high temperature environment, and ensuring continuous operation.

[0041] When the infrared thermal imager 5 is not needed, the cooling fan 41 is first rotated from the upright position to the folded position, and then the two folding plates 3 are folded inward, so that the upper shell 1 and the lower shell 2 gradually approach each other, and finally form a second space 62 with a volume much smaller than the first space 61. The folded cooling fan 41 is completely contained in the second space 62 and will not produce any external protrusions.

[0042] By unfolding and folding the folding plate 3 to achieve spatial switching, combined with the state adjustment of the cooling fan 41, the heat dissipation efficiency is ensured to meet the high-temperature working requirements of the infrared thermal imager 5 during use, while the overall volume is greatly reduced when not in use. This solves the problem of poor portability of existing heat dissipation covers and meets the actual needs of power inspection personnel for lightweight and portable equipment.

[0043] In some possible embodiments, please refer to Figure 3 , Figure 4 and Figure 5 A flip plate 21 is rotatably mounted on the lower housing 2, and a power supply 22 for supplying power to the cooling fan 41 is mounted on the flip plate 21.

[0044] When the cooling fan 41 is in an upright position, the flip plate 21 can be rotated so that the power supply 22 is located outside the first space 61, so that the power supply 22 avoids the infrared thermal imager 5. When the cooling fan 41 is in a folded position, the flip plate 21 can be rotated so that the power supply 22 is housed inside the second space 62.

[0045] It should be noted that the power supply 22 and the cooling fan 41 are connected by a pluggable power cable.

[0046] When the cooling fan 41 is in the upright working state, the flip plate 21 can be rotated and adjusted so that the power supply 22 is located outside the first space 61, thereby avoiding interference from the power supply 22 to the infrared thermal imager 5, ensuring the stability of the infrared thermal imager 5 and the unobstructed flow of the cooling air duct.

[0047] When the cooling fan 41 is in the folded-down position, the flip plate 21 can be rotated so that the power supply 22 is completely contained inside the second space 62, realizing the integrated storage of the power supply 22 and the cooling fan 41, avoiding damage to exposed parts during transportation, and further compressing the overall volume.

[0048] In some possible embodiments, please refer to Figure 2 , Figure 4 and Figure 5 A mounting plate 42 is hinged to the lower housing 2, and a cooling fan 41 is mounted on the mounting plate 42. A positioning component is provided at the end of the mounting plate 42 opposite to the hinge axis. Connecting blocks 7 suitable for engaging with the positioning component are fixedly provided on both the upper housing 1 and the flip plate 21.

[0049] When the cooling fan 41 is in an upright position, the positioning component engages with the connecting block 7 on the upper housing 1. When the cooling fan 41 is in a folded-down position and the flip plate 21 is rotated so that the power supply 22 is housed inside the second space 62, the positioning component engages with the connecting block 7 on the flip plate 21.

[0050] When the cooling fan 41 needs to be adjusted to an upright position to dissipate heat from the infrared thermal imager 5, the mounting plate 42 is rotated to make the cooling fan 41 upright. At this time, the positioning component on the mounting plate 42 gradually approaches the connecting block 7 on the upper housing 1. When the mounting plate 42 is rotated to the preset position, the positioning component engages with the connecting block 7 on the upper housing 1, thereby fixing the mounting plate 42 and preventing the cooling fan 41 from rotating due to vibration, thus ensuring stable heat dissipation direction.

[0051] When the inspection is finished and the cooling fan 41 needs to be adjusted to the folded position, first rotate the flip plate 21 until the power supply 22 is accommodated in the second space 62, then release the locking of the positioning component and the connecting block 7 of the upper housing 1, rotate the mounting plate 42 to make the cooling fan 41 folded, and then lock the positioning component and the connecting block 7 on the flip plate 21 to fix the mounting plate 42 so that the cooling fan 41 is in the folded position, preventing the cooling fan 41 from rotating randomly when carried.

[0052] By engaging the positioning component with different connecting blocks 7, the cooling fan 41 is reliably fixed in two states, solving the problem of the cooling fan 41 shifting. At the same time, the engaging structure is easy to operate, requiring no additional tools, and is suitable for the needs of outdoor inspection and quick equipment adjustment, further improving the structural stability and efficiency of the equipment.

[0053] In some possible embodiments, please refer to Figure 7 The positioning assembly includes a positioning post 421 and a positioning spring 422. The positioning post 421 is slidably mounted on the mounting plate 42. The two ends of the positioning spring 422 are fixed to the mounting plate 42 and the positioning post 421 respectively, and are used to push the positioning post 421 out of the mounting plate 42. Each connecting block 7 has a slot 71 suitable for engaging with the positioning post 421.

[0054] The positioning post 421 is slidably mounted on the mounting plate 42. The two ends of the positioning spring 422 are fixed to the mounting plate 42 and the positioning post 421 respectively. In the natural state, the positioning spring 422 extends and pushes the positioning post 421 out of the mounting plate 42. The connecting block 7 is provided with a slot 71 that is adapted to the positioning post 421.

[0055] When the mounting plate 42 is rotated to make the cooling fan 41 stand upright, the positioning post 421 moves with the mounting plate 42 and gradually approaches the slot 71 of the connecting block 7 of the upper housing 1. When in contact, the positioning post 421 is squeezed by the connecting block 7 and slides into the mounting plate 42 against the elastic force of the positioning spring 422. When the mounting plate 42 is in place and the positioning post 421 is aligned with the slot 71, the positioning spring 422 pushes the positioning post 421 into the slot 71 to complete the snap-fit ​​fixation. Automatic positioning can be achieved without manual pressing. After snap-fit, the positioning post 421 is stably fixed in the slot 71 and can resist vibration and collision external forces to ensure the stability of the cooling fan 41.

[0056] In some possible embodiments, each slot 71 is an arc-shaped slot, and the positioning post 421 has an arc-shaped end suitable for engaging with the arc-shaped slot.

[0057] When the mounting plate 42 is rotated to bring the positioning post 421 closer to the slot 71, the curved end guides the positioning post 421 to slide smoothly into the slot 71 through its own curvature, avoiding jamming or stuck phenomena when contacting right angles or sharp structures, thus improving the success rate of engagement and the smoothness of operation. When disengaging, the curved end also reduces the frictional resistance of the positioning post 421 exiting the slot 71, making the unlocking operation smoother.

[0058] In some possible embodiments, the rotation axis of the flip plate 21 is perpendicular to the rotation axis of the mounting plate 42.

[0059] Since the axes are perpendicular to each other, the rotation of the flip plate 21 and the mounting plate 42 are in different spatial planes. When adjusting the mounting plate 42, the position of the flip plate 21 will not hinder its rotation. Conversely, when adjusting the flip plate 21, it will not be affected by the state of the mounting plate 42, and the operation sequence is flexible.

[0060] In some possible embodiments, please refer to Figure 1 , Figure 2 and Figure 6 A telescopic rod 8 is connected between the upper housing 1 and the lower housing 2. The telescopic rod 8 has a locking element for locking the telescopic length. The telescopic rod 8 has a first length and a second length.

[0061] When the folding panel 3 is in the unfolded state, the telescopic rod 8 is locked at a first length to keep the folding panel 3 in the unfolded state. When the folding panel 3 is in the folded state, the telescopic rod 8 is locked at a second length to keep the folding panel 3 in the folded state.

[0062] To ensure the structural stability of the folding plate 3 in both unfolded and folded states, and to prevent accidental deformation from affecting its use or portability, the telescopic rod 8, in conjunction with the locking mechanism, provides reliable support for the upper housing 1 and the lower housing 2. Pulling the upper housing 1 and the lower housing 2 gradually unfolds the folding plate 3 from its folded state, causing the telescopic rod 8 to extend accordingly. When the folding plate 3 is fully unfolded and the upper housing 1 and lower housing 2 form a stable first space 61, the telescopic rod 8 reaches a preset first length. The locking mechanism then locks the telescopic rod 8, preventing it from extending or retracting on its own. This provides rigid support to the upper housing 1 and lower housing 2, ensuring the infrared thermal imager 5 is stably placed within the first space 61.

[0063] Release the locking mechanism and push the upper housing 1 and lower housing 2 closer together. The folding plate 3 folds down and the telescopic rod 8 shortens. When the folding plate 3 is fully folded to form a compact second space 62, the telescopic rod 8 reaches the preset second length. Use the locking mechanism again to lock the telescopic rod 8, so that the upper housing 1 and lower housing 2 remain stably close together, preventing the folding plate 3 from accidentally unfolding during carrying, which would increase the volume or cause parts to collide.

[0064] Compared to relying solely on the structure of the folding plate 3 to maintain its state, the locking support of the telescopic rod 8 can significantly improve structural stability, solving the problem of the folding plate 3 being prone to accidental deformation. At the same time, the telescopic rod 8 has a lightweight structure, which will not add extra burden to the equipment, further adapting to the portability and stability requirements of outdoor inspections.

[0065] In some possible embodiments, please refer to Figure 1 , Figure 2 and Figure 6 The telescopic rod 8 includes an inner tube 81 and an outer tube 82. The inner tube 81 is hinged to the upper housing 1. The outer tube 82 is slidably sleeved on the inner tube 81 and is hinged to the lower housing 2.

[0066] When the folding plate 3 is unfolded, the upper shell 1 and the lower shell 2 move away from each other. The inner tube 81 rotates with the upper shell 1, and the outer tube 82 rotates with the lower shell 2. At the same time, the inner tube 81 slides outward relative to the outer tube 82, causing the telescopic rod 8 to extend. The hinged structure ensures that the telescopic rod 8 can adapt to the positional changes of the upper shell 1 and the lower shell 2, avoiding bending and damage caused by rigid tension.

[0067] When the folding plate 3 is folded, the upper shell 1 and the lower shell 2 move closer to each other, and the inner tube 81 slides inward relative to the outer tube 82, which shortens the telescopic rod 8. The hinge structure also adapts to the positional changes of the upper shell 1 and the lower shell 2 to ensure a smooth telescopic process.

[0068] In some possible embodiments, please refer to Figure 8 The locking mechanism includes a sliding sleeve 83, a locking pin 84, and a locking spring 85. The sliding sleeve 83 is fixedly mounted on the inner tube 81. The locking pin 84 is slidably mounted within the sliding sleeve 83, with its sliding direction along the radial direction of the inner tube 81. The locking spring 85 is fixed at both ends to the sliding sleeve 83 and the locking pin 84, respectively, and is used to push the locking pin 84 out of the sliding sleeve 83.

[0069] Please see Figure 1 and Figure 2 The outer tube 82 has a first locking hole 821 and a second locking hole 822. When the locking pin 84 is inserted into the first locking hole 821, the telescopic rod 8 is at its first length. When the locking pin 84 is inserted into the second locking hole 822, the telescopic rod 8 is at its second length.

[0070] Pull the inner tube 81 and the outer tube 82 together. The inner tube 81 slides outward. When the telescopic rod 8 reaches the first length, the first locking hole 821 of the outer tube 82 aligns with the locking pin 84. The locking spring 85 pushes the locking pin 84 into the first locking hole 821 to complete the locking. The positioning can be completed automatically without manual operation.

[0071] Manually press the locking pin 84 to overcome the elastic force of the locking spring 85 and exit the first locking hole 821. Push the inner tube 81 to slide inward. When the telescopic rod 8 reaches the second length, the second locking hole 822 is aligned with the locking pin 84. The locking spring 85 pushes the locking pin 84 to insert again, completing the locking.

[0072] No tools are required for operation; unlocking is achieved simply by pressing with a finger, making it suitable for outdoor one-handed operation. The elasticity of the locking spring 85 ensures that the locking pin 84 is firmly inserted into the first locking hole 821 or the second locking hole 822, preventing it from easily falling out even with vibration, thus ensuring locking reliability.

[0073] In some possible embodiments, please refer to Figure 1 , Figure 2 and Figure 3 The folding plate 3 includes a first plate 31 and a second plate 32. The first plate 31 is hinged to the upper shell 1. The two ends of the second plate 32 are hinged to the first plate 31 and the lower shell 2, respectively.

[0074] The first plate 31 is hinged to the upper shell 1, and the two ends of the second plate 32 are hinged to the first plate 31 and the lower shell 2 respectively. The two-section structure can achieve a greater range of folding.

[0075] When the folding plate 3 is unfolded, the upper shell 1 and the lower shell 2 move away from each other. The first plate 31 rotates around the hinge point with the upper shell 1, and the second plate 32 rotates synchronously around the hinge point with the lower shell 2. Finally, the first plate 31 and the second plate 32 extend into an approximately flat plane, together with the upper shell 1 and the lower shell 2, forming a stable first space 61.

[0076] When the folding plate 3 is folded, it pushes the upper shell 1 and the lower shell 2 closer to each other. The first plate 31 rotates inward, and the second plate 32 folds inward synchronously with the first plate 31. Finally, the first plate 31 and the second plate 32 fit together, which greatly shortens the overall length of the folding plate 3, allowing the upper shell 1 and the lower shell 2 to be closer together. The volume of the second space 62 is further reduced, and the portability is significantly improved.

[0077] In summary, the heat dissipation and protective housing for an infrared thermal imager provided by this invention, compared with the prior art, has an upper housing 1 and a lower housing 2 connected by symmetrically arranged folding plates 3 to form a main frame. When the folding plates 3 are in the unfolded state and the cooling fan 41 is upright relative to the lower housing 2, the upper housing 1, the lower housing 2, and the two folding plates 3 together form a first space 61 for accommodating the infrared thermal imager 5. At this time, the exhaust end of the cooling fan 41 directly faces the infrared thermal imager 5, which can effectively enhance airflow circulation, improve heat dissipation efficiency, and ensure that the equipment continues to work stably in high-temperature environments.

[0078] When the equipment needs to be stored and carried, the folding plate 3 can be folded and retracted, and the cooling fan 41 can be hinged and rotated to a folded state. At this time, the upper shell 1, the lower shell 2 and the folding plate 3 form a second space 62 with a significantly reduced volume, and the cooling fan 41 is completely housed inside it, which greatly improves the compactness and portability of the overall structure and meets the actual needs of power inspection personnel for lightweight and convenient carrying of equipment.
