Abstract
Description
Technical Field
[0001] This utility model relates to the field of camera housing technology, and in particular to a high-temperature resistant and explosion-proof camera housing. Background Technology
[0002] Currently, existing camera housings (such as patent publication number: CN220668926U) disclose a camera housing assembly. By pressing the push plate, the locking plate is pushed to compress the locking spring, which allows the locking rod to move into the mounting base. The sealing plate can be slidably installed on the surface of the mounting base through the connecting plate. When the push plate is released, the locking spring pushes the locking plate outward due to its elastic potential energy, so that the locking rod engages with the connecting hole, allowing the camera to be quickly installed into the mounting base. This enables rapid installation of the camera and also facilitates disassembly by the staff.
[0003] In the aforementioned patent, the camera has multiple heating units installed inside. The contact area between the outer shell and the internal heating elements is limited, making it difficult for local high temperatures to spread quickly. If the temperature exceeds the threshold, it will lead to increased noise, decreased frame rate, or even shutdown. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a high-temperature resistant explosion-proof camera housing, which solves the technical problems of limited contact area between the housing and internal heat-generating components, difficulty in rapid dissipation of localized high temperatures, and the resulting increase in noise, decrease in frame rate, or even shutdown when the temperature exceeds a threshold.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A high-temperature resistant explosion-proof camera housing includes a camera body and two housing bodies, with a heat dissipation plate fixedly installed on the inner side of each housing body;
[0007] Two reinforcing ribs are fixedly installed on the inner side of each heat sink plate, an inner plate is fixedly installed on the inner side of each reinforcing rib, and multiple heat-conducting columns are fixedly installed inside each inner plate. A flexible pad is fixedly installed at the end of each heat-conducting column.
[0008] Preferably, each of the reinforcing ribs has a heat-absorbing strip fixedly installed at both ends, and each heat-absorbing strip is made of flexible graphite material;
[0009] Each heat sink is fixedly equipped with a connector strip at its side end, and a sealing port is fixedly installed on the upper half of each heat sink.
[0010] Each of the outer casings is fixedly fitted with a delivery pipe at its top, and each delivery pipe is fixedly fitted with a one-way valve inside.
[0011] Preferably, two fixing cylinders are fixedly installed on the surface of each of the outer shell bodies, two mounting seats are fixedly installed on the surface of each of the outer shell bodies, and a knob rod is rotatably installed inside each of the mounting seats;
[0012] The two outer shell bodies are installed symmetrically to each other, and each heat sink has at least two grooves inside.
[0013] Compared with the prior art, the present invention has the following beneficial effects;
[0014] In this invention, multiple heat-conducting pillars are arranged in a matrix inside the inner plate, and the flexible pads at the ends contact the side of the camera body. Especially for areas with high heat generation, heat is directed into the interior of the heat-conducting pillars. The ends of the heat-conducting pillars are submerged in water inside the outer shell, which accelerates heat dissipation. The heat-absorbing strips at the side ends of the reinforcing ribs are made of flexible graphite material. When the water flows in the cavity of the outer shell, the water flow impacts the heat-absorbing strips, causing them to bend and deform, and then they return to their original position, continuously agitating the water and improving the heat dissipation effect.
[0015] In this invention, the two outer shells are assembled by the cooperation of the plug strip and the sealing port, as well as the locking of the knob rod. The installation process is simple and convenient. By rotating the knob rod in the opposite direction, it rotates inside the mounting base and the end is screwed into the fixed cylinder. Utilizing the characteristic that the thread helix angle is less than the friction angle, self-locking is achieved, tightening the two outer shells so that they fit tightly together, further ensuring the sealing performance and structural stability of the shells under various working conditions, and enhancing the explosion-proof performance.

[0022] This application provides a high-temperature resistant explosion-proof camera housing, which effectively solves the problems of limited contact area between the housing and internal heat-generating components, difficulty in rapid dissipation of localized high temperatures, and increased noise, decreased frame rate, or even shutdown caused by temperatures exceeding a threshold. Multiple heat-conducting pillars are arranged in a matrix inside the inner panel, with flexible pads at the ends contacting the side of the camera body. Especially for areas with high heat generation, heat is directed into the interior of the heat-conducting pillars. The ends of the heat-conducting pillars are submerged in water inside the housing, accelerating heat dissipation. The heat-absorbing strips at the side ends of the reinforcing ribs are made of flexible graphite material. When water flows through the cavity of the housing body, the water flow impacts the heat-absorbing strips, causing them to bend and deform before returning to their original position, continuously agitating the water and improving the heat dissipation effect.
[0023] Example
[0024] like Figure 1 - Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem that the limited contact area between the outer shell and the internal heating element makes it difficult for local high temperatures to dissipate quickly, and that temperatures exceeding a threshold can lead to increased noise, decreased frame rate, or even system crashes. The overall approach is as follows:
[0025] To address the problems existing in the prior art, this utility model provides a high-temperature resistant explosion-proof camera housing, including a camera body 11 and two housing bodies 12. A heat dissipation plate 13 is fixedly installed on the inner side of each housing body 12. The heat dissipation plate 13 is installed in the cavity inside the housing body 12. At the same time, the heat dissipation plate 13 and the reinforcing rib 16 are combined with each other. The heat dissipation plate 13 and the reinforcing rib 16 provide support for the housing body 12, increasing the strength of the housing body 12 and the inner plate 18.
[0026] Two reinforcing ribs 16 are fixedly installed on the inner side of each heat sink 13. An inner plate 18 is fixedly installed on the inner side of each reinforcing rib 16. Multiple heat-conducting columns 21 are fixedly installed inside each inner plate 18. A flexible pad 22 is fixedly installed at the end of each heat-conducting column 21. By moving the two outer shell bodies 12, the outer shell bodies 12 are combined with each other. At the same time, the side ends of the heat sink 13 are equipped with plug strips 14 and sealing ports 15. The plug strips 14 are inserted into the interior of another set of sealing ports 15, so that the cavities inside the two outer shell bodies 12 are connected to each other. At the same time, the outer shell bodies 12 are aligned and installed. The side end of the mounting base 24 is connected to the fixing cylinder 23. By rotating the knob in the opposite direction... The lever 25 is rotated inside the mounting base 24, and the end of the lever 25 is rotated into the fixed cylinder 23, tightening the two outer shell bodies 12 so that the two outer shell bodies 12 fit tightly together, and water is supplied to the inside of the outer shell body 12 to reduce the temperature of the camera body 11. At the same time, heat conduction pillars 21 are installed on the inner side of the outer shell body 12 and the inner plate 18. Multiple heat conduction pillars 21 are arranged in a matrix inside the inner plate 18. The heat conduction pillars 21 are in contact with the side end of the camera body 11. For areas with high heat generation, heat is introduced into the interior of the heat conduction pillars 21. At the same time, the end of the heat conduction pillar 21 is directly immersed in the water inside the outer shell body 12 to increase the heat dissipation speed.
[0027] Each reinforcing rib 16 has a heat-absorbing strip 17 fixedly installed on both sides. Each heat-absorbing strip 17 is made of flexible graphite. The reinforcing rib 16 and the heat-absorbing strip 17 are fixed inside the cavity of the outer shell body 12. The reinforcing rib 16 increases the structural strength. Water flows in the cavity of the outer shell body 12. The water flow continuously impacts the heat-absorbing strip 17, causing the heat-absorbing strip 17 to bend and deform at the side ends of the reinforcing rib 16. At the same time, the heat-absorbing strip 17 can return to its original position. Through the continuous bending and returning of the heat-absorbing strip 17, the water inside the outer shell body 12 is agitated.
[0028] Each heat sink 13 has a connector strip 14 fixedly installed on its side end, and a sealing port 15 fixedly installed on the upper half of each heat sink 13. The connector strip 14 can be inserted into the interior of the sealing port 15. The connector strip 14 has a multi-layer structure. The connector strip 14 is squeezed against the interior of the sealing port 15. After the connector strip 14 is deformed, it fills the gap inside the sealing port 15 to prevent water leakage, and at the same time allows the two outer shell bodies 12 to be combined and connected.
[0029] Each outer casing 12 is fixedly installed with a delivery pipe 19 at its top. Each delivery pipe 19 is fixedly installed with a one-way valve inside. A pump is connected through one of the delivery pipes 19 to deliver water into the delivery pipe 19. Because a one-way valve is installed inside the delivery pipe 19, the water can only flow in a fixed direction inside the delivery pipe 19 to prevent backflow and reduce the circulation speed of the water.
[0030] Two fixing cylinders 23 are fixedly installed on the surface of each outer shell body 12, and two mounting seats 24 are fixedly installed on the surface of each outer shell body 12. A knob rod 25 is rotatably installed inside each mounting seat 24. By rotating the knob rod 25 in the forward direction, the knob rod 25 rotates inside the mounting seat 24. At the same time, the end of the knob rod 25 rotates into the interior of the fixing cylinder 23. Since the thread helix angle of the fixing cylinder 23 and the knob rod 25 is less than the friction angle, the knob rod 25 stops rotating, and the fixing cylinder 23 and the knob rod 25 can lock themselves.
[0031] Two outer shell bodies 12 are installed symmetrically to each other. Each heat sink 13 has at least two grooves inside. The two outer shell bodies 12 are symmetrically combined and installed. A delivery pipe 19 is installed at the top of the outer shell body 12 respectively. Water enters and exits through the two delivery pipes 19 respectively. The water source can circulate in the cavity inside the two outer shell bodies 12.
[0032] Working principle:
[0033] The first step is to symmetrically assemble and install the two outer shell bodies 12. During installation, move the two outer shell bodies 12 so that the plug strip 14 at the side end of the heat sink 13 is inserted into the sealing port 15 on the other outer shell body 12. The plug strip 14 has a multi-layer structure and deforms after insertion, filling the gap inside the sealing port 15 to achieve a good seal and prevent water leakage. At the same time, the cavities inside the two outer shell bodies 12 are connected to each other. Then, by rotating the knob rod 25 in the opposite direction, it is rotated inside the mounting base 24 and the end is screwed into the fixing cylinder 23. Utilizing the characteristic that the thread helix angle is less than the friction angle, self-locking is achieved, tightening the two outer shell bodies 12 so that they fit tightly together.
[0034] The heat sink 13 is installed in the cavity inside the outer shell 12 and is combined with the reinforcing rib 16 to support the outer shell 12 and the inner plate 18, thereby enhancing the overall structural strength. The heat-absorbing strip 17 at the side end of the reinforcing rib 16 is made of flexible graphite. When water flows in the cavity of the outer shell 12, the water flow impacts the heat-absorbing strip 17, causing it to bend and deform, and then it returns to its original position, continuously stirring the water and improving the heat dissipation effect. Multiple heat-conducting columns 21 are arranged in a matrix inside the inner plate 18, and the flexible pads 22 at the ends contact the side end of the camera body 11. Especially for areas with high heat generation, heat is directed into the interior of the heat-conducting columns 21, and the ends of the heat-conducting columns 21 are submerged in water inside the outer shell, accelerating heat dissipation.
[0035] The second step involves rotating the knob 25 in the opposite direction after the outer shell body 12 is assembled, causing it to rotate inside the mounting base 24. The end of the knob is screwed into the fixing cylinder 23, and the self-locking is achieved by utilizing the characteristic that the thread helix angle is less than the friction angle, thus tightening the two outer shell bodies 12. During installation, the plug strip 14 at the side end of the heat sink 13 is inserted into the sealing port 15 on the other outer shell body 12. The plug strip 14 has a multi-layer structure and deforms after insertion, filling the gap inside the sealing port 15 to achieve a good seal and prevent external explosive gases from entering the interior of the shell. At the same time, the heat sink 13 is installed in the internal cavity of the outer shell body 12 and combines with the reinforcing rib 16 to support the outer shell body 12 and the inner plate 18, thereby enhancing the overall structural strength.
[0036] Water is supplied to the camera body 11 by connecting a pump through one of the delivery pipes 19. Due to the presence of a one-way valve inside the delivery pipe 19, the water can only flow in a fixed direction to prevent backflow from affecting the circulation speed. The water circulates in the cavities inside the two outer shells 12, continuously carrying away heat and reducing the temperature of the camera body 11, thus achieving efficient heat dissipation and ensuring stable operation of the camera in high-temperature environments.
[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
