Description

Technical Field

[0001] The present invention belongs to the technical field of mobile power supply equipment, and specifically relates to a portable film and television socket box. Background Art

[0002] A film and television socket box is a dedicated power distribution device that adapts to the function of a distribution panel in a film and television shooting scene. As a secondary power distribution node, its core function is to convert the main power supply (such as the output of a generator or a substation) into multiple independent and controllable AC output circuits. This device usually adopts a modular distribution panel structure, integrates industrial sockets of multiple specifications and is equipped with independent circuit breakers, so as to adapt to the different load requirements of lighting groups, cameras, special effects equipment, etc. It is a key hub device for realizing flexible power distribution and centralized control in the modern film and television on-site temporary power supply system.

[0003] In the actual film and television shooting power supply system, the thermal management optimization of the mobile socket box is an important point to ensure power supply safety. Currently, traditional socket boxes usually rely on a passive heat dissipation system composed of a fixed axial flow fan and heat dissipation holes (such as a portable socket box with the application number "201921074597.9", the specific solution is: accelerating the air flow inside the socket box body through a heat dissipation fan to improve the heat dissipation effect of the components inside the socket box); Since mobile power supply equipment needs to balance a compact structure and efficient heat dissipation, the above-mentioned conventional passive heat dissipation solutions are difficult to optimize the air flow organization in a limited space, and the phenomenon of heat accumulation is significant. Especially when multiple high-power film and television lights take power at the same time, the temperature rise rate of key components such as circuit breakers and contactors far exceeds the safety threshold, posing a hidden danger of electrical fire.

Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] As Figure 1 、 Figure 2 shown, the present invention provides a portable video and audio socket box, including a socket box 1, an accommodation area 2 for accommodating electronic components is provided in the socket box 1, and further includes: A function box 3, which is hollow inside and communicates with the accommodation area 2 in the socket box 1; A flow guide plate 4 is provided at the connection between the function box 3 and the accommodation area 2, and an air inlet filter 5 is communicated with the function box 3; An air guide member 6 is provided in the function box 3, and the air suction side is communicated with the air inlet filter 5; A baffle 7 is provided in the function box 3, which is used to divide the inner cavity of the function box 3 on the air supply side of the air guide member 6 into a first cavity 41 and a second cavity 42; The first chamber 41 is in communication with the accommodation area 2, and the air flow on the air supply side of the air guiding member 6 enters the first chamber 41 and the second chamber 42; The Peltier element 8 is disposed through the baffle 7 and the cooling end is located in the first chamber 41 to cool the flowing air.

[0023] The above heat dissipation structure actively sucks and filters air through the air guiding member 6, combines the baffle 7 for air diversion and the Peltier element 8 for temperature reduction to construct "air cooling + Peltier cooling" dual heat dissipation, and blows the cold air flow to the electronic components through the deflector 4 for active temperature reduction, comprehensively solving the problems of low efficiency and easy heat accumulation in the traditional heat dissipation scheme.

[0024] As Figure 2 、 Figure 3 shown, it further includes: A rotating cylinder 9 is rotatably disposed at the connection between the functional box 3 and the accommodation area 2, and the deflector 4 is fixedly disposed in the rotating cylinder 9; A gear ring 10 is fixedly disposed on the outer peripheral edge of the rotating cylinder 9; A double-headed toothed rod 11 meshes with the gear ring 10 and penetrates through the functional box 3 and is rotatably connected to the functional box 3; A motion conversion member 12 is drivingly connected to one end of the double-headed toothed rod 11, and the other end is connected to the output end of the air guiding member 6; As the output end of the air guiding member 6 drives the motion conversion member 12, the double-headed toothed rod 11 is driven to rotate circumferentially. The double-headed toothed rod 11 meshes with the gear ring 10 to drive the rotating cylinder 9 and the deflector 4 to rotate circumferentially, and the cooling air flow is introduced into the accommodation area 2 along with the circumferential rotation of the deflector 4.

[0025] When the air guiding member 6 operates, it synchronously drives the deflector 4 to rotate circumferentially, so that the cooling air flow is introduced into the accommodation area 2 in a spiral or tangential form, breaking through the limitation of traditional unidirectional air supply. The rotating air diversion can expand the heat dissipation coverage range, evenly distribute the air flow to different areas of the electronic components, avoid local heat accumulation, and at the same time enhance the air flow disturbance and improve the heat exchange efficiency. It is especially suitable for the heat dissipation scenario of densely arranged high-power components. Moreover, by reusing the power of the air guiding member 6 as the driving source of the deflector 4, no additional motor is required, the structure is compact and the energy consumption is lower.

[0026] As Figure 3 、 Figure 5 shown, the air guiding member 6 includes: A double-shaft motor 61 is disposed in the functional box 3, and a guide fan 62 is provided at one output end; The motion conversion member 12 includes: A steering reducer 121 is drivingly connected to the other output end of the double-shaft motor 61; A transmission toothed rod 122 is connected to the output end of the steering reducer 121; Driving gears 123 are provided at both ends of the double-headed toothed rod 11 and are respectively meshed with the transmission toothed rod 122 and the gear ring 10.

[0027] The dual-axis motor 61 drives the guide fan 62 and the steering speed reducer 121 simultaneously, realizing the reuse of a single power source. The guide fan 62 directly blows air for heat dissipation, and the other output end transmits power to the rotating cylinder 9 through the steering speed reducer 121, the transmission rack 122, and the transmission gears 123 at both ends of the double-headed rack 11. The deflector 4 rotates to enhance the uniformity of air flow coverage and avoid the cost and energy consumption of additional driving devices.

[0028] As Figure 5 、 Figure 9 shown, it further includes: A steel wire rope 13, connected to the transmission rack 122; A brush barrel 14, fixedly connected to the other end of the steel wire rope 13. An operating cylinder 15 is rotatably arranged on the outer side of the brush barrel 14, and brush hairs 16 are arranged on the outer side of the end.

[0029] Extend the power of the air guide member 6 to the cleaning module. The brush barrel 14 can be operated to clean the socket box 1 according to actual needs, realizing the synchronous operation of the heat dissipation and self-cleaning functions. The brush hairs 16 can rotate with the operating cylinder 15 to automatically perform cleaning at different cleaning angles. The integrated solution takes into account the heat dissipation efficiency and cleaning needs without additional energy consumption.

[0030] As Figure 5 、 Figure 6 shown, a hexagonal rod 17 is fixedly arranged at one end of the steel wire rope 13 away from the brush barrel 14. A magnet ring 18 is arranged to slide radially along the outer side of the hexagonal rod 17. A moving plate 19 is rotatably arranged on the outer side of the magnet ring 18. The end of the transmission rack 122 close to the steel wire rope 13 is a magnetic attraction end 20; As the moving plate 19 drives the magnet ring 18 to slide radially along the outer side of the hexagonal rod 17 to magnetize / demagnetize with the magnetic attraction end 20, the steel wire rope 13 is driven to rotate / stop rotating synchronously with the transmission rack 122.

[0031] Through the magnetic attraction type clutch design (magnet ring 18 and magnetic attraction end 20), the flexible linkage control of the steel wire rope 13 and the transmission rack 122 is realized. By radially adjusting the position of the magnet ring 18 on the moving plate 19, the transmission connection / disconnection state can be quickly switched without mechanical buckles or complex structures, improving the start-stop response speed; the self-adaptive adjustment of the magnetic attraction force ensures the stability of power transmission and simplifies the operation at the same time.

[0032] As Figure 4 、 Figure 5 、 Figure 6 shown, it further includes: A filter box 21, which is hollow inside and is arranged on the functional box 3. The transmission rack 122, the steering speed reducer 121, and the hexagonal rod 17 are located inside the filter box; Inside the filter box 21, there is a magnetic support seat 22. The hexagonal rod 17 is rotatably arranged inside the magnetic support seat 22. The magnet ring 18 moves along the direction away from / towards the transmission rack 122 to magnetize / demagnetize with the magnetic support seat 22. One end of the moving plate 19 penetrates through the filter box 21. The filter box 21 is provided with a first sliding hole 23 for the displacement of the moving plate 19. And the moving plate 19 is provided with a first cover plate 24 covering the first sliding hole 23. The filter box 21 is provided with an air outlet 25, and the air outlet 25 is communicated with the air inlet filter port 5. The filter box 21 is also communicated with an air inlet 26. A filter mesh sleeve 27 is arranged between the air inlet 26 and the air outlet 25. The flowing air passes through the filter mesh sleeve 27 and is filtered into the air inlet filter port 5.

[0033] The filter box 21 integrates the transmission components and the air flow filtering function. The hexagonal rod 17 is fixed by the magnetic support seat 22 and the clutch control is realized by the sliding of the magnet ring 18 in cooperation. The moving plate 19 and the first cover plate 24 close the first sliding hole 23 to prevent dust from invading. At the same time, the filter mesh sleeve 27 secondary purifies the air at the air inlet 26 to ensure the cleanliness of the air flow entering the functional box. As Figure 4 、 Figure 5 shown, it also includes: A housing 28 is located inside the filter box 21 and outside the transmission rack 122, the steering reducer 121 and the hexagonal rod 17. One end of the moving plate 19 penetrates through the housing 28. The housing 28 is provided with a second sliding hole 29 for the displacement of the moving plate 19. And the moving plate 19 is provided with a second cover plate 30 covering the second sliding hole 29.

[0034] The newly added housing 28 conducts secondary sealing and isolation on the transmission components. With the dynamic covering design of the second sliding hole 29 and the second cover plate 30, a double-layer dust-proof barrier is formed, effectively blocking the path of dust invading the transmission mechanism (such as the gear 123, the clutch assembly). The layered protection ensures the flexible sliding of the moving plate 19 while maintaining the independent cleanliness of the air flow path and the mechanical transmission space inside the filter box 21. It not only reduces the risk of mechanical jamming or wear caused by dust, but also facilitates layered maintenance (such as cleaning the filter mesh sleeve or overhauling the transmission components separately).

[0035] As Figure 4 、 Figure 6 、 Figure 8 、 Figure 9 shown, it also includes: A rubber hose 31 is located outside the steel wire rope 13 and one end is communicated with the inside of the filter box 21. The blocking plate 32 is connected to the moving plate 19 and is located outside the steel wire rope 13. The moving plate 19 moves in a direction away from / close to the transmission gear rod 122 to drive the blocking plate 32 to cover / not cover the connection between the rubber hose 31 and the filter box 21; The operating cylinder 15 is hollow inside, and the other end of the rubber hose 31 is connected to the operating cylinder 15; The brush cylinder 14 is hollow inside and its end is connected to the inner cavity of the operating cylinder 15. A suction hole 33 is provided on the brush cylinder 14 at the bristles 16. More specifically, Figure 11 As shown, the brush cylinder 14 includes a first cylinder and a second cylinder which are hollow inside. The first cylinder is rotatably arranged inside the operating cylinder 15 and is connected to the inner cavity of the operating cylinder 15. One end of the first cylinder is fixedly connected to the other end of the wire rope 13. The other end of the first cylinder is provided with a threaded sleeve. The outer side of the threaded sleeve is threadedly connected with the second cylinder. The second cylinder is located outside the operating cylinder 15. The bristles 16 and the suction holes 33 are both arranged on the second cylinder. The suction hole 33 of the brush barrel 14 can be cleaned or replaced by disassembly, so that the suction hole 33 can be handled when it is blocked after long-term use; An air guide passage is formed between the rubber hose 31 and the steel wire rope 13 , the inner cavity of the operating cylinder 15 and the brush cylinder 14 , and the suction hole 33 . The impurities are guided along the air guide passage and filtered through the filter mesh sleeve 27 to enter the air inlet filter port 5 as the brush bristles 16 clean.

[0036] The socket box 1 is provided with a holder for placing the operating cylinder 15 and a rotating chuck for placing the rubber hose 31 and the wire rope 13; Through the integrated design of the rubber hose 31 and the air guide channel in the brush tube 14, the adsorption of clean impurities is achieved. The dust swept by the bristles 16 is introduced into the filter sleeve 27 through the closed flow channel formed by the suction hole 33, the operating tube 15 and the rubber hose 31, and then re-enters the heat dissipation air duct after secondary filtration, forming a self-cleaning circulation system; the blocking plate 32 is linked with the moving plate 19 to control the opening and closing of the airflow, and is opened / closed by the operator according to actual needs.

[0037] like Figure 2 , Figure 7 , Figure 10 As shown, it also includes: The partition 34 is disposed in the first chamber 41 and is divided into a cold chamber 411 and a hot chamber 412 , and the hot chamber 412 is connected to the second chamber 42 ; One side of the silica gel desiccant sleeve 35 penetrates through the functional box 3 and the partition 34 and is inserted into the cold chamber 411 and the hot chamber 412 .

[0038] Also includes: The guide plate 36 is disposed in the first cavity 41 and is located on a side of the silica gel desiccant sleeve 35 away from the guide plate 36; An exhaust pipe 37 has one end communicating with the accommodation area 2 and the other end communicating with the heat chamber 412 and is located on one side of the silica gel desiccant sleeve plate 35 close to the heating end of the refrigerating sheet 8; An exhaust sleeve 38 is provided on the functional box 3 and communicates with the heat chamber 412, and the communication position is located on one side of the silica gel desiccant sleeve plate 35 away from the heating end of the refrigerating sheet 8.

[0039] The cold and heat chambers are separated by a partition plate 34 and the silica gel desiccant sleeve plate 35 is integrated. The exhaust pipe 37 and the exhaust sleeve 38 are combined to form a closed loop. The cold chamber 411 uses the refrigerating sheet 8 and the silica gel desiccant sleeve plate 35 to cool and dehumidify, enter the accommodation area 2 to cool and dissipate heat from the electronic components. The airflow heated after heat exchange is introduced into the heat chamber 412 through the exhaust pipe 37, and the heat chamber 412 is assisted to dry the lower half of the silica gel desiccant sleeve plate 35 by heating the air together with the heating end of the refrigerating sheet 8, and then is discharged through the exhaust sleeve 38. The desiccant can be recycled, reducing the replacement frequency, and taking into account both the heat dissipation efficiency and the moisture-proof reliability of the equipment.

[0040] The working principle and usage process of the present invention: The double-shaft motor 61 is started to drive the guide fan 62 to rotate. Air enters from the air inlet 26 of the filter box 21, passes through the filter mesh sleeve 27 for filtration, enters from the air outlet 25 into the air inlet filter port 5, and then enters the functional box 3. The cooling end of the refrigerating sheet 8 cools the airflow entering the first chamber 41, and the cooled airflow flows into the accommodation area 2 through the first chamber 41 to cool the electronic components; At the same time, the other output end of the double-shaft motor 61 drives the transmission rack 122 to rotate through the steering speed reducer 121. The transmission rack 122 drives the transmission gears 123 at both ends of the double-headed rack 11 to rotate, so that the double-headed rack 11 rotates circumferentially, and then drives the rotating cylinder 9 and the guide plate 4 to rotate circumferentially through the engaged gear ring 10, so that the cooling airflow will be more evenly introduced into the accommodation area 2 along with the circumferential rotation of the guide plate 4, that is, the cooling operation is completed.

[0041] During this process, part of the airflow on the air supply side of the guide fan 62 will also be introduced into the second chamber 42 and heated by the heating end of the refrigerating sheet 8 to form a cold and hot double-circulation air duct. The airflow that has undergone heat exchange through the accommodation area 2 will also be discharged into the heat chamber 412 through the exhaust pipe 37. The silica gel desiccant sleeve plate 35 is inserted into the cold chamber 411 and the heat chamber 412. The cooling airflow is dried and dehumidified by the silica gel desiccant sleeve plate 35 in the cold chamber 411. After dehumidification, the silica gel desiccant sleeve plate 35 can be manually adjusted so that the dehumidified side is inserted into the heat chamber 412, and the side that has not been dehumidified is located in the cold chamber 411 to continue the dehumidification operation. The heating airflow can heat the dehumidified silica gel desiccant sleeve plate 35 to maintain its drying performance. Finally, the airflow is dissipated into the external environment through the exhaust sleeve 38.

[0042] When cleaning is required, move the moving plate 19 so that the magnet ring 18 slides radially along the outer side of the hexagonal rod 17 and magnetically attracts the magnetic attracting end 20 of the transmission rack 122. At this time, the blocking plate 32 does not cover the connection between the rubber hose 31 and the filter box 21, and the rotation of the transmission rack 122 is transmitted to the brush cylinder 14 through the steel wire rope 13, so that the bristles 16 on the outer side of the brush cylinder 14 start to rotate. The operator can hold the operation cylinder 15 to perform the cleaning operation; During the cleaning process, the airflow generated by the air guiding member 6 forms a guiding air flow path through the rubber hose 31, the operation cylinder 15, the inner cavity of the brush cylinder 14 and the suction holes 33, sucking the impurities cleaned by the bristles 16 into the filter box 21. After being filtered by the filter mesh sleeve 27, the impurities enter the air inlet filter port 5, and the cleaning and impurity removal operation is completed; After the cleaning is completed, pull the moving plate 19 so that the magnet ring 18 magnetically attracts the magnetic attracting support seat 22. At the same time, the blocking plate 32 covers the connection between the rubber hose 31 and the filter box 21, and the brush cylinder 14 stops rotating, and the cleaning operation ends.
