Description

Technical Field

[0001] The present invention relates to the technical field of multi-channel synchronous test recorders, and particularly to a multi-channel synchronous test recorder. Background Art

[0002] A multi-channel synchronous test recorder is a device used to synchronously record and test multiple signal sources, and is usually applied to industries such as power, communication, and electronics for measuring and analyzing the time relationship, waveform characteristics, and system behavior of multiple signals. The multi-channel synchronous test recorder can efficiently capture and record the dynamic changes of multiple signals, and is widely used in fields that require precise synchronous acquisition and timing analysis.

[0003] Currently, when a multi-channel synchronous test recorder is in use, it will heat up. Existing devices usually use a fan and a dust removal net to achieve heat dissipation and dust prevention during use. The dust removal net needs to be cleaned regularly to maintain the ventilation and dust prevention effects. However, since the dust removal net is generally located in a relatively concealed or inaccessible position of the device, the cleaning effect is not good, resulting in poor air flow and thus affecting the heat dissipation effect. When cleaning the dust removal net, the dust removed is easily sucked into the device interior by the fan, causing secondary pollution, thereby affecting the long-term stable operation of the device and making the practicality of the device poor. Summary of the Invention

The heat dissipation mechanism includes four diversion shells fixedly installed on the top of the deflector. The four diversion shells are respectively located at the four sides of the multi-channel synchronous test and recording device. The diversion shell is semi-circular. A plurality of air outlet holes are arranged on the arc surface of the diversion shell. The diameters of the plurality of air outlet holes gradually increase from the center of the top of the diversion shell to both sides. Four diversion grooves are arranged inside the deflector. The four diversion grooves are circumferentially arranged around the embedding groove and communicated with the embedding groove. The end of the diversion groove away from the embedding groove is communicated with the diversion shell on the corresponding side. A temperature detection structure is arranged inside the multi-channel synchronous test and recording device.

[0011] Preferably, the vibration mechanism includes a fixed frame fixedly installed on the inner wall of the installation pipe. The fixed frame is located below the first dust removal net. The center of the top of the fixed frame is fixedly installed with a second electric telescopic rod. The top of the fixed frame is fixedly connected with a moving ring through a first spring. The moving ring is slidably connected with the inner wall of the installation pipe. The top of the moving ring is fixedly installed with four T-shaped rods. The tops of the four T-shaped rods are fixedly connected with the bottom of the first dust removal net. The four T-shaped rods are circumferentially arranged around the second electric telescopic rod. The outer walls of the four T-shaped rods are respectively slidably connected with knocking rings, and the knocking rings are fixedly connected with the second electric telescopic rod through connecting rods.

[0012] Preferably, the collection mechanism includes an installation box fixedly installed at the bottom of the inner wall of the outer box.

The I-shaped block is slidably connected with the connecting square pipe. The I-shaped block is used to close the connecting square pipe.

[0013] Preferably, two motors are fixedly installed on one side of the installation box away from the connecting square pipe. The output ends of the two motors are respectively fixedly connected with L-shaped rotating plates. The mutually remote sides of the two L-shaped rotating plates are in contact with the inner wall of the installation box. The mutually close ends of the two L-shaped rotating plates are respectively fixedly installed with strip brushes. The second dust removal net is located above the two L-shaped rotating plates.

[0014] Preferably, a fixed housing is fixedly installed on the top of the second dust removal net. The top of the inner wall of the fixed housing is fixedly installed with a third electric telescopic rod. The top of the second dust removal net and the top of the inner wall of the installation box are fixedly connected with a second spring.

[0015] Compared with the existing technology, the advantages of the present invention are as follows:

[0016] By using the fan to operate in reverse and blow air downward, the present invention enables the air to circulate along the installation pipe, connecting square pipe, installation box and connecting elbow pipe, ensuring that the dust can be quickly carried away by the air flow after falling from the first dust removal net, entering the interior of the installation box, and being blocked by the second dust removal net, effectively capturing and storing the fallen dust, avoiding dust leakage. The closing function of the first electric telescopic rod and the I-shaped block can effectively isolate the first dust removal net after cleaning, preventing the dust that has been cleaned from being inhaled again after the fan is restarted, effectively preventing the dust from entering the system again, and ensuring the long-term stable operation of the equipment.

[0017] Through the combined design of the guiding ring and the shielding plate, the present invention can flexibly adapt to the connection requirements of different numbers of plugs and external devices to be detected. When not in use, the shielding plate can effectively block the guiding ring to prevent dust and other debris from entering, keeping the connection part clean. When the plug needs to be used, the shielding plate will automatically adjust its position and no longer block the guiding ring, facilitating the smooth insertion of the plug. At the same time, the inserted plug will be limited by the shielding plate to prevent accidental detachment and ensure the stability of the connection.

[0018] By setting devices such as a blower, a deflector plate, and a diversion shell, the present invention can evenly disperse air to different positions of a multi-channel synchronous test recording and wave device, achieving comprehensive heat dissipation for the device. By setting air outlet holes and diversion grooves with different diameters, the air flow path is optimized, improving the heat dissipation efficiency and avoiding the risk of device damage due to excessive temperature. The temperature detection structure monitors the device temperature in real time. When the temperature exceeds the preset threshold, it will automatically trigger a safety protection mechanism to pull out the plug from the insertion hole through the fourth electric telescopic rod, avoiding damage to the device caused by continuous high temperature, thereby extending the service life of the device.

[0019] By setting the second electric telescopic rod to continuously stretch and retract, the knocking ring continuously impacts the T-shaped rod, and then vibrates the first dust removal net, which can effectively shake off the dust and impurities attached to the dust removal net, thus ensuring the cleanliness of the dust removal net and avoiding the reduction of device performance due to dust accumulation. The second electric telescopic rod does not directly contact the first dust removal net, but indirectly acts through the knocking ring and the T-shaped rod, effectively reducing the physical impact on the dust removal net, reducing the risk of damage to the dust removal net, and extending the service life of the dust removal net. The first spring also makes the first dust removal net shake up and down when vibrating, helping to further loosen and remove the dust on the net surface and improving the dust removal effect.

[0020] The present invention effectively removes the dust on the second dust removal net by setting a strip brush. The combination of this brushing and the light knocking of the third electric telescopic rod ensures more thorough cleaning, especially for the dust and fine particles that are tightly attached, which can be effectively shaken off and removed. Through the coordinated work of two groups of motors and the L-shaped rotating plate, the entire cleaning process can ensure uniform cleaning of the surface of the second dust removal net without dead corners, thereby enhancing the dust removal efficiency. The detachable structure at the lower end of the installation box is convenient for cleaning. All the fallen dust will eventually be collected at the bottom of the installation box, facilitating subsequent cleaning work and improving the convenience of use. Through the isolation effect of the L-shaped rotating plate, the cleaned dust is effectively separated and will not re-mix into the system, ensuring the efficiency and effect of cleaning.

Detailed implementation manner

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to 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 of the embodiments.

[0034] Refer to Figures 1 to 11 , a multi-channel synchronous test recorder, including an outer box 1, a multi-channel synchronous test recording device 3 and multiple groups of plug-in components. The top of the outer box 1 is provided with an upper cover. A flow guide plate 5 is fixedly installed on the inner wall of the outer box 1. The multi-channel synchronous test recording device 3 is fixedly installed on the top of the flow guide plate 5 through a connecting member. Support columns 2 are fixedly installed at the four corners of the inner wall of the outer box 1, and the bottom of the support column 2 penetrates the bottom of the outer box 1 to raise the bottom of the outer box 1, increasing the stability of the device, avoiding direct contact between the bottom of the outer box 1 and the ground, and reducing the impact of vibration or moisture on the device. The flow guide plate 5 is fixedly connected to the support column 2. The four support columns 2 are respectively in contact with the four corners of the multi-channel synchronous test recording device 3. Dust-proof nets are fixedly connected between the four sides of the multi-channel synchronous test recording device 3 and the inner wall of the outer box 1, and the dust-proof nets are fixedly connected to the support columns 2. The four support columns 2 separate the four sides of the multi-channel synchronous test recording device 3.

[0035] On the top of the multi-channel synchronous test and recording device 3, there are multiple groups of socket holes 10, and the multiple groups of socket holes 10 correspond to multiple groups of plug-in components. On the top of the multi-channel synchronous test and recording device 3, there is a covering frame 4. Two fourth electric telescopic rods 33 are fixedly installed on the top of the multi-channel synchronous test and recording device 3, and the two fourth electric telescopic rods 33 are symmetrically distributed on both sides of the covering frame 4. The telescopic ends of the two fourth electric telescopic rods 33 are respectively fixedly installed with extension plates, and the extension plates are fixedly connected to the covering frame 4. When the fourth electric telescopic rod 33 extends and retracts, the covering frame 4 is driven to move through the extension plate. Multiple groups of guide rings 34 are fixedly connected to the top of the covering frame 4, and the multiple groups of guide rings 34 respectively correspond to the multiple groups of socket holes 10. A group of fifth electric telescopic rods 44 are fixedly installed on the inner wall of the covering frame 4. Two connecting bars 37 are slidably connected to the inner wall of the covering frame 4, and the two connecting bars 37 are symmetrically distributed on both sides of a group of fifth electric telescopic rods 44, and the connecting bars 37 are parallel to the fifth electric telescopic rods 44. Multiple groups of mounting shells 35 are fixedly connected between the two connecting bars 37, and the multiple groups of mounting shells 35 are evenly distributed in the covering frame 4. The telescopic end of the fifth electric telescopic rod 44 is fixedly connected to the mounting shell 35 on the corresponding side. Multiple shielding plates 36 are respectively slidably connected to one side of the multiple groups of mounting shells 35 away from the fifth electric telescopic rods 44, and the multiple shielding plates 36 respectively correspond to the multiple groups of socket holes 10. Multiple fixing plates 39 are respectively fixedly installed on the inner walls of the multiple mounting shells 35, and the multiple fixing plates 39 respectively correspond to the multiple shielding plates 36. A third spring 38 is fixedly connected between the shielding plate 36 and the corresponding fixing plate 39. The side of the shielding plate 36 away from the mounting shell 35 is an arc end, and the arc end is composed of a long arc surface and a short arc surface, and the long arc surface is located on the side of the short arc surface away from the third spring 38. The plug-in component is connected to an external device to be detected through a wire. The plug-in component includes a plug 40. A fixing rod 41 is fixedly connected to the top of the plug 40. A clamping groove 42 is arranged on the side wall of the fixing rod 41. A sliding strip 43 is fixedly connected to the side wall of the fixing rod 41. A sliding groove corresponding to the sliding strip 43 is opened on the guide ring 34.

[0036] The position of multiple mounting shells 35 is adjusted by the fifth electric telescopic rod 44, so that the position of the shielding plate 36 can be adjusted. When the plug-in assembly is not connected to the plug-in hole 10, the shielding plate 36 blocks the guiding ring 34. When the multi-channel synchronous test recording device 3 needs to be used, multiple shielding plates 36 move away from the guiding ring 34 and no longer block the guiding ring 34. The shielding plate 36 effectively prevents dust or sundries from entering the connection part of the plug-in hole 10 and the plug 40, avoids the influence of external sundries on the device, significantly improves the reliability of the device, and extends the service life. Subsequently, the sliding bar 43 is embedded into the sliding groove on the guiding ring 34, and the plug 40 is embedded downward into the plug-in hole 10. At this time, the long arc surface of the shielding plate 36 contacts the outer surface of the fixed rod 41. The setting of the guiding ring 34 and the sliding bar 43 ensures that the insertion angle of the plug 40 into the plug-in hole 10 is accurate, avoiding damage to the plug 40 or insecure plugging due to improper insertion angle, and can effectively improve the stability and accuracy of the plugging. After all the plugs 40 required for detection are embedded into the corresponding plug-in holes 10, the fifth electric telescopic rod 44 is used to push multiple mounting shells 35, and the shielding plate 36 corresponding to the plug-in hole 10 without the inserted plug 40 blocks the guiding ring 34 again to avoid dust and other sundries from falling in. The shielding plate 36 corresponding to the plug-in hole 10 with the inserted plug 40 is pushed by the fixed rod 41 and slides along the inner wall of the mounting shell 35 in the direction of pulling the third spring 38. After the mounting shell 35 stops moving, the shielding plate 36 will be embedded into the engaging groove 42 to limit the fixed rod 41, making the connection of the plug 40 more firm and reducing the faults or poor contacts caused by the loosening of the plug 40 during the use of the device.

[0037] An embedding groove 11 is provided at the center of the bottom of the flow guide plate 5. The embedding groove 11 is fixedly connected with an installation pipe 8. One end of the installation pipe 8 away from the embedding groove 11 penetrates through the bottom of the outer box 1 and is fixedly connected with the outer box 1. The installation pipe 8 is flush with the bottom of the outer box 1 and is in communication with the outside. Four flow guide shells 6 are fixedly installed on the top of the flow guide plate 5. The four flow guide shells 6 are respectively located on the four sides of the multi-channel synchronous test and recording device 3. The flow guide shell 6 is semi-circular. A plurality of air outlet holes 9 are provided on the arc surface of the flow guide shell 6. The diameters of the plurality of air outlet holes 9 gradually increase from the center of the top of the flow guide shell 6 to both sides. Four flow guide grooves 7 are provided inside the flow guide plate 5. The four flow guide grooves 7 are circumferentially and arrayedly distributed around the embedding groove 11 and are communicated with the embedding groove 11. One end of the flow guide groove 7 away from the embedding groove 11 is communicated with the corresponding side flow guide shell 6. A fan 12 is fixedly installed inside the installation pipe 8. The support column 2 raises the outer box 1 to ensure that the fan 12 can effectively circulate air into the box body, improve the internal heat dissipation and ventilation conditions, prevent the equipment from overheating. A first dust removal net 22 is provided on the inner wall of the installation pipe 8. The first dust removal net 22 is located below the fan 12. The external gas is inhaled into the embedding groove 11 through the installation pipe 8 by the fan 12. The first dust removal net 22 can filter dust and sundries in the air, avoid these substances from entering the equipment internal, ensure the cleanliness of the equipment operating environment, reduce the risk that may be brought by dust accumulation inside the equipment, and improve the long-term stability and reliability of the equipment. The air inside the embedding groove 11 flows out from the four sides of the multi-channel synchronous test and recording device 3 through the flow guide groove 7, the flow guide shell 6 and the air outlet holes 9, effectively taking away the heat generated by the equipment, playing a role in heat dissipation, ensuring its operation in a stable working environment, and avoiding failures and performance degradation caused by overheating. The design of the air outlet holes 9 enables the air to be evenly distributed to the four sides of the equipment. Especially when the diameters of the air outlet holes 9 gradually increase, the distribution of the air flow becomes more uniform, ensuring that the air can fully contact the surface of the equipment, improving the heat dissipation effect. This uniform air distribution helps to avoid the occurrence of local overheating phenomena, improve the overall heat dissipation efficiency of the equipment. At the same time, when the gas flows inside the flow guide groove 7, it can take away the heat transferred from the multi-channel synchronous test and recording device 3 to the flow guide plate 5, realizing the heat dissipation of the multi-channel synchronous test and recording device 3, enhancing the heat dissipation effect. A temperature detection structure is provided inside the multi-channel synchronous test and recording device 3. When the temperature inside the multi-channel synchronous test and recording device 3 exceeds the preset threshold, the fourth electric telescopic rod 33 extends, causing the covering frame 4 to move upward. Through the limit of the guide ring 34 and the push of the shielding plate 36, the fixed rod 41 drives the plug 40 to be toggled upward, and the plug 40 is separated from the socket hole 10, ensuring that the equipment will not continue to operate at high temperature, preventing the equipment from shutting down due to overheating failure, and also reducing the aging of internal components caused by high temperature, improving the stability and long-term reliability of the equipment.

[0038] At the bottom of the inner wall of the outer box 1, an installation box 14 is fixedly installed. The installation box 14 and the installation pipe 8 are fixedly connected and communicated with a connecting elbow 13. The connection port of the connecting elbow 13 and the installation pipe 8 is located above the fan 12. The installation box 14 and the installation pipe 8 are fixedly connected and communicated with a connecting square pipe 15. The connecting elbow 13 is located above the connecting square pipe 15. The connection port of the connecting square pipe 15 and the installation pipe 8 is located below the first dust removal net 22. The outer wall of the installation pipe 8 is fixedly installed with a first electric telescopic rod 16. The bottom of the first electric telescopic rod 16 is fixedly connected with an I-shaped block 17. The I-shaped block 17 is slidably connected with the connecting square pipe 15. The I-shaped block 17 is used to close the connecting square pipe 15. The inner wall of the installation pipe 8 is fixedly installed with a fixing frame 18. The fixing frame 18 is located below the first dust removal net 22. The center of the top of the fixing frame 18 is fixedly installed with a second electric telescopic rod 19. The top of the fixing frame 18 is fixedly connected with a moving ring 20 through a first spring 21. The moving ring 20 is slidably connected with the inner wall of the installation pipe 8. The top of the moving ring 20 is fixedly installed with four T-shaped rods 23. The tops of the four T-shaped rods 23 are fixedly connected with the bottom of the first dust removal net 22. The first dust removal net 22 is slidably connected with the inner wall of the installation pipe 8. The four T-shaped rods 23 are circumferentially arranged around the second electric telescopic rod 19. The outer walls of the four T-shaped rods 23 are respectively slidably connected with knocking rings 25. The four knocking rings 25 are respectively fixedly connected with the second electric telescopic rod 19 through connecting rods 24. When cleaning the first dust removal net 22, pull out the plug 40 and close the upper cover of the outer box 1. The first electric telescopic rod 16 drives the I-shaped block 17 to move upward, and the connecting square pipe 15 is no longer closed. Then the fan 12 rotates in the reverse direction and blows air downward, so that the air circulates along the installation pipe 8, the connecting square pipe 15, the installation box 14, and the connecting elbow 13. The second electric telescopic rod 19 continuously and quickly stretches and retracts, drives the knocking rings 25 to continuously impact the upper ends of the T-shaped rods 23 through the connecting rods 24, thereby making the first dust removal net 22 vibrate, shaking off dust and other impurities on the first dust removal net 22. The first spring 21 makes the first dust removal net 22 shake up and down while being vibrated. The second electric telescopic rod 19 does not directly contact the first dust removal net 22. The fallen dust enters the installation box 14 along with the air.

[0039] On one side of the installation box 14 away from the connecting square pipe 15, two motors 30 are fixedly installed. The output ends of the two motors 30 are respectively fixedly connected with L-shaped rotating plates 31. The mutually remote sides of the two L-shaped rotating plates 31 are in contact with the inner wall of the installation box 14. The mutually close ends of the two L-shaped rotating plates 31 are clamped up and down (as Figure 8As shown in the figure, strip brushes 32 are fixedly installed at the ends of two L-shaped rotating plates 31 close to each other. A second dust removal net 26 is slidably connected to the inner wall of the installation box 14. The second dust removal net 26 is located above the two L-shaped rotating plates 31. A fixed housing 28 is fixedly installed at the top of the second dust removal net 26. A third electric telescopic rod 29 is fixedly installed at the top of the inner wall of the fixed housing 28. The telescopic end of the third electric telescopic rod 29 continuously expands and contracts to strike the second dust removal net 26. A second spring 27 is fixedly connected between the top of the second dust removal net 26 and the top of the inner wall of the installation box 14. When cleaning the lower surface of the second dust removal net 26, the upper L-shaped rotating plate 31 rotates upward first, and then the lower L-shaped rotating plate 31 rotates. The strip brush 32 brushes the lower surface of the second dust removal net 26 to brush off the dust. The two L-shaped rotating plates 31 repeatedly brush below the second dust removal net 26. At the same time, the third electric telescopic rod 29 continuously expands and contracts to gently strike the second dust removal net 26. The dust falling from the lower end surface of the second dust removal net 26 accumulates at the bottom inside the installation box 14. The two groups of L-shaped rotating plates 31 reset. At this time, the collected dust is separated by the two groups of L-shaped rotating plates 31. The lower end of the installation box 14 is provided with a detachable structure for easy disassembly and cleaning.

[0040] In the present invention, the plug 40 is connected to an external device to be detected. The fixing rod 41 is fixedly arranged at the upper end of the plug 40. A plurality of guiding rings 34 are arranged through the upper end of the covering frame 4, and the plurality of guiding rings 34 correspond to the plurality of insertion holes 10 one by one. A sliding groove matching the sliding bar 43 is formed on the guiding ring 34 for restricting the insertion angle of the plug 40 and the fixing rod 41. The plurality of mounting shells 35 are connected by connecting bars 37. Both ends of the fifth electric telescopic rod 44 are fixedly connected to the inner wall of the covering frame 4 and one of the mounting shells 35 respectively. Both of the two connecting bars 37 are slidably connected to the inner wall of the covering frame 4. The plurality of shielding plates 36 are slidably arranged inside the mounting shells 35. The position of the plurality of mounting shells 35 can be adjusted by the fifth electric telescopic rod 44, so that the position of the plurality of shielding plates 36 can be adjusted. The arc end of the shielding plate 36 is composed of a longer arc surface and a shorter arc surface. When not in use, the plurality of shielding plates 36 are respectively moved to the lower ends of the plurality of guiding rings 34 to contact the guiding rings 34 through the fifth electric telescopic rod 44, and the guiding rings 34 can be shielded. When the multi-channel synchronous test recording device 3 needs to be used, the upper cover of the outer box 1 is opened. Then, the plurality of shielding plates 36 are moved a certain distance by the contraction of the fifth electric telescopic rod 44, so that the shielding plates 36 no longer shield the guiding rings 34. Then, the plug 40 is inserted into the insertion hole 10, and the sliding bar 43 is inserted into the sliding groove. At this time, the long arc surface of the shielding plate 36 contacts the outer surface of the fixing rod 41. After the plurality of plugs 40 required for detection are inserted into the insertion holes 10, the plurality of mounting shells 35 are pushed to move by the fifth electric telescopic rod 44. The shielding plate 36 corresponding to the insertion hole 10 without the inserted plug 40 will shield the guiding ring 34 to prevent dust and other sundries from falling in. The shielding plate 36 corresponding to the insertion hole 10 with the inserted plug 40 will be pushed and moved by the fixing rod 41, so that the shielding plate 36 slides along the mounting shell 35. After the mounting shell 35 stops moving, the shielding plate 36 will be inserted into the clamping groove 42 to limit the fixing rod 41 and prevent the plug 40 from separating from the insertion hole 10.

[0041] The multi-channel synchronous test and recording device 3 is provided with a temperature detection structure inside. Four groups of support columns 2 are embedded at the lower end of the outer box 1. Dust-proof nets are arranged between the four groups of support columns 2 and the multi-channel synchronous test and recording device 3. The four groups of support columns 2 are in contact with the four corners of the multi-channel synchronous test and recording device 3. Through the four groups of support columns 2, the lower end of the outer box 1 can be raised, facilitating the intake of air during heat dissipation. At the same time, the four groups of support columns 2 can separate the four sides of the multi-channel synchronous test and recording device 3. The lower end of the installation pipe 8 is fixedly connected to the lower end of the outer box 1, and the upper end of the installation pipe 8 is fixedly connected to the inner wall of the embedding groove 11. During use, the blower 12 is started. Through the blower 12, external gas can be inhaled into the embedding groove 11 through the installation pipe 8. When the air passes through the first dust removal net 22, dust will be filtered. Four diversion grooves 7 are formed inside the diversion plate 5. The four diversion grooves 7 are respectively connected to the embedding groove 11 and the four diversion shells 6. A plurality of air outlet holes 9 are formed on the outer surface of the diversion shell 6. The diameters of the plurality of air outlet holes 9 gradually increase from the center of the diversion shell 6 to both sides. The air entering and leaving the embedding groove 11 through the blower 12 can flow out through the diversion shell 6, the diversion grooves 7 and the air outlet holes 9. Since at the same flow rate, the larger the cross-section, the larger the flow rate. Through the setting of the air outlet holes 9, the air can be more evenly dispersed to different positions on one side of the multi-channel synchronous test and recording device 3. Through the setting of the plurality of diversion shells 6, the four sides of the multi-channel synchronous test and recording device 3 can be cooled. At the same time, when the gas flows inside the diversion grooves 7, the heat transferred from the multi-channel synchronous test and recording device 3 to the diversion plate 5 can be taken away, realizing the heat dissipation of the multi-channel synchronous test and recording device 3 and preventing its temperature from being too high. When the temperature inside the multi-channel synchronous test and recording device 3 exceeds the preset threshold, the fourth electric telescopic rod 33 extends a certain distance. Since the fourth electric telescopic rod 33 is fixedly connected to one side of the covering frame 4 through the extension plate, the covering frame 4 can be moved upward through the fourth electric telescopic rod 33. Through the limitation of the guide ring 34 and the push of the baffle plate 36, the fixing rod 41 is pushed upward, so that the plug 40 can be pulled out from the insertion hole 10, avoiding damage caused by continuous use leading to a continuous increase in temperature. The third spring 38 is used to pull the baffle plate 36 back to its original position.

[0042] When it is necessary to clean the first dust removal net 22, after pulling out the plug 40, close the upper cover of the outer box 1 to seal the upper opening of the outer box 1. Then, make the I-shaped block 17 move upward through the first electric telescopic rod 16, so that the connecting square pipe 15 is no longer blocked. Subsequently, make the fan 12 rotate in the reverse direction, so that the fan 12 blows air downward, causing the air to circulate along the installation pipe 8, the connecting square pipe 15, the installation box 14, the connecting elbow 13 and the installation pipe 8. Then, make the second electric telescopic rod 19 continuously and rapidly extend and retract. Since the knocking ring 25 is fixedly connected to the outer surface of the second electric telescopic rod 19 through the connecting rod 24, and the knocking ring 25 is movably connected to the T-shaped rod 23, when the second electric telescopic rod 19 continuously extends and retracts, the knocking ring 25 will continuously strike the upper end of the T-shaped rod 23, causing the first dust removal net 22 to vibrate, and the dust and other impurities on the first dust removal net 22 can be shaken off. The fixing frame 18 is used to support the second electric telescopic rod 19. Through the first spring 21, the first dust removal net 22 can shake up and down while being vibrated, which can improve the dust removal effect. Moreover, the second electric telescopic rod 19 does not directly contact the first dust removal net 22, which can reduce the possibility of damage to the first dust removal net 22 due to impact. The fallen dust can enter the interior of the installation box 14 along with the air. Subsequently, the dust will be blocked by the second dust removal net 26. After a period of time, turn off the fan 12. At this time, the dust accumulates on the lower surface of the second dust removal net 26 and inside the installation box 14. First, start the motor 30 of one group to make the upper L-shaped rotating plate 31 rotate upward. During this process, the strip brush 32 will brush across the lower surface of the second dust removal net 26, and the dust can be brushed off. Then, make the other group of L-shaped rotating plates 31 also rotate upward. Through the motors 30 of the two groups, the two groups of L-shaped rotating plates 31 repeatedly brush below the second dust removal net 26. During this process, make the third electric telescopic rod 29 continuously extend and retract to continuously tap the second dust removal net 26, which can promote the falling of the dust on the second dust removal net 26 and the two groups of L-shaped rotating plates 31. The fallen dust can fall to the lower end of the interior of the installation box 14 for collection. Then, make the two groups of L-shaped rotating plates 31 reset. At this time, the collected dust is separated by the two groups of L-shaped rotating plates 31. The lower end of the installation box 14 is set as a detachable structure for easy cleaning. Through the second spring 27, the second dust removal net 26 can be reset. Then, through the first electric telescopic rod 16, the I-shaped block 17 closes the inside of the connecting square pipe 15, which can realize the cleaning of the first dust removal net 22, and at the same time can gather and process the cleaned dust to avoid being inhaled again by the fan 12 during repeated use. The present invention can dissipate heat and prevent dust for the multi-channel synchronous test recording device 3 during use. Through the setting of the baffle 36, it can adapt to the use of different numbers of plugs 40, and can also separate the plug 40 from the socket hole 10 when the temperature is too high, reducing the possibility of equipment damage. At the same time, it can realize the automatic cleaning of the first dust removal net 22, and can avoid the cleaned dust being inhaled repeatedly, affecting the normal use of the first dust removal net 22.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
