Description

Technical Field

[0001] The invention relates to the technical field of multi-channel synchronous test recorders, in particular 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. It is usually used in industries such as power, communications, and electronics to measure and analyze the time relationship, waveform characteristics, and system behavior of multiple signals. A 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] At present, multi-channel synchronous test recorders will generate heat when in use. Existing equipment usually uses fans and dust removal nets to achieve heat dissipation and dust prevention when in use. The dust removal nets need to be cleaned regularly to maintain ventilation and dust prevention effects. However, since the dust removal nets are generally located in a relatively hidden or inaccessible position of the equipment, the cleaning effect is not good, resulting in poor air flow, which affects the heat dissipation effect. When cleaning the dust removal nets, the cleaned dust is easily sucked into the equipment by the fan, causing secondary pollution, thereby affecting the long-term stable operation of the equipment and making the equipment less practical.

[0015] Compared with the prior art, the advantages of the present invention are: The present invention utilizes the fan to blow air downward in reverse operation, so that air circulates along the installation tube, the connecting square tube, the installation box and the connecting bent pipe, ensuring that dust can be quickly carried away by the airflow after falling from the first dust removal net, enter the interior of the installation box, and be blocked by the second dust removal net, effectively capturing and storing the fallen dust to prevent dust leakage. The sealing function of the first electric telescopic rod and the I-shaped block can effectively isolate the first dust removal net after cleaning, preventing the cleaned dust from being sucked in again after the fan is restarted, effectively preventing dust from re-entering the system, and ensuring the long-term stable operation of the equipment.

[0016] The present invention can flexibly adapt to the connection requirements of different numbers of plugs and external devices to be detected through the combined design of the guide ring and the baffle plate. When not in use, the baffle plate can effectively block the guide ring to prevent dust and other debris from entering and keep the connection part clean. When the plug needs to be used, the baffle plate will automatically adjust its position and no longer block the guide ring, thereby facilitating the smooth insertion of the plug. At the same time, the inserted plug will be limited by the baffle plate to prevent accidental falling off, thereby ensuring the stability of the connection.

[0017] The present invention can evenly disperse air to different positions of the multi-channel synchronous test recording equipment by arranging devices such as fans, guide plates and guide shells, thereby achieving comprehensive heat dissipation of the equipment. By arranging air outlets and guide grooves of different diameters, the air circulation path is optimized, the heat dissipation efficiency is improved, and the risk of damage to the equipment due to excessive temperature is avoided. The temperature detection structure monitors the temperature of the equipment in real time. When the temperature exceeds a preset threshold, the safety protection mechanism is automatically triggered, and the plug is pulled out of the plug hole through the fourth electric telescopic rod to avoid damage to the equipment due to continuous high temperature, thereby extending the service life of the equipment.

[0018] The present invention arranges the second electric telescopic rod to continuously extend and retract, so that the knocking ring continuously hits the T-bar, thereby vibrating the first dust removal net, which can effectively shake off the dust and impurities attached to the dust removal net, thereby ensuring the cleanliness of the dust removal net and avoiding degradation of equipment 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-bar, 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, which helps to further loosen and remove dust on the net surface, thereby improving the dust removal effect.

[0019] The present invention effectively removes dust on the second dust removal net by arranging a strip brush. This brushing movement combined with the tapping of the third electric telescopic rod ensures more thorough cleaning, especially for tightly attached dust and fine particles, which can be effectively shaken off and removed. Through the coordinated work of the two sets of motors and the L-shaped rotating plate, the entire cleaning process can ensure that the surface of the second dust removal net is evenly cleaned without leaving dead corners, thereby enhancing the dust removal efficiency. The detachable structure at the lower end of the installation box is convenient for cleaning, and all fallen dust will eventually be collected at the bottom of the installation box, which is convenient for subsequent cleaning work and improves the convenience of use. Through the isolation effect of the L-shaped rotating plate, the cleaned dust is effectively separated and will not be re-mixed into the system, thereby ensuring the efficiency and effect of cleaning.

[0024] The top of the multi-channel synchronous test recording device 3 is provided with multiple groups of plug holes 10, and the multiple groups of plug holes 10 correspond to the multiple groups of plug components. The top of the multi-channel synchronous test recording device 3 is provided with a cover frame 4. The top of the multi-channel synchronous test recording device 3 is fixedly installed with two fourth electric telescopic rods 33, and the two fourth electric telescopic rods 33 are symmetrically distributed on both sides of the cover 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 cover frame 4. The fourth electric telescopic rod 33 is telescopic, and the cover frame 4 is driven to move by the extension plate. The top of the cover frame 4 is fixedly connected with multiple sets of guide rings 34, and the multiple sets of guide rings 34 correspond to the multiple sets of plug holes 10 respectively. A set of fifth electric telescopic rods 44 are fixedly installed on the inner wall of the cover frame 4. Two connecting strips 37 are slidably connected to the inner wall of the cover frame 4. The two connecting strips 37 are symmetrically distributed on both sides of a set of fifth electric telescopic rods 44, and the connecting strips 37 are parallel to the fifth electric telescopic rods 44. Multiple sets of mounting shells 35 are fixedly connected between the two connecting strips 37. The multiple groups of mounting shells 35 are evenly distributed in the cover frame 4, the telescopic end of the fifth electric telescopic rod 44 is fixedly connected to the mounting shell 35 on the corresponding side, the multiple groups of mounting shells 35 are slidably connected to the side away from the fifth electric telescopic rod 44 with multiple shielding plates 36, the multiple shielding plates 36 correspond to the multiple groups of plug holes 10, the inner walls of the multiple mounting shells 35 are respectively fixedly installed with multiple fixing plates 39, the multiple fixing plates 39 correspond to the multiple shielding plates 36, and the shielding plates 36 and the corresponding fixing plates 39 are fixedly connected with third elastic Spring 38, the side of the baffle plate 36 away from the mounting shell 35 is set as an arc end, 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 assembly is connected to the external device to be detected through a wire, the plug-in assembly includes a plug 40, the top of the plug 40 is fixedly connected with a fixing rod 41, the side wall of the fixing rod 41 is provided with a locking groove 42, the side wall of the fixing rod 41 is fixedly connected with a sliding bar 43, and a sliding groove corresponding to the sliding bar 43 is opened on the guide ring 34.

[0025] The position of the plurality of mounting shells 35 is adjusted by the fifth electric telescopic rod 44, so that the position of the baffle plate 36 can be adjusted. When the plug-in assembly is not connected to the plug-in hole 10, the baffle plate 36 will block the guide ring 34. When the multi-channel synchronous test recording device 3 is needed, the plurality of baffle plates 36 will be away from the guide ring 34 and no longer block the guide ring 34. The baffle plate 36 effectively prevents dust or debris from entering the connection part between the plug-in hole 10 and the plug 40, avoids the influence of external debris on the equipment, significantly improves the reliability of the equipment, and prolongs its service life. Subsequently, the sliding bar 43 is embedded in the sliding groove on the guide ring 34, and the plug 40 is downwardly embedded in the plug-in hole 10. At this time, the long arc surface of the baffle plate 36 contacts the outer surface of the fixing rod 41, and the setting of the guide ring 34 and the sliding bar 43 ensures that the insertion angle of the plug 40 and the plug-in hole 10 The degree of precision is accurate, and damage to the plug 40 or loose insertion due to improper insertion angle is avoided, which can effectively improve the stability and accuracy of the insertion. After all the plugs 40 required for detection are embedded in the corresponding plug-in holes 10, the fifth electric telescopic rod 44 is used to push the multiple groups of mounting shells 35, and the shielding plates 36 corresponding to the plug-in holes 10 where the plugs 40 are not inserted will block the guide ring 34 again to prevent dust and other debris from falling in. The shielding plates 36 corresponding to the plug-in holes 10 where the plugs 40 are inserted are squeezed by the fixing rod 41 and slide 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 in the engaging groove 42 to limit the fixing rod 41, so that the plug 40 is more firmly connected, reducing the failure or poor contact caused by the looseness of the plug 40 during the use of the equipment.

[0026] An embedding groove 11 is provided at the bottom center of the guide plate 5, and a mounting tube 8 is fixedly connected to the embedding groove 11. One end of the mounting tube 8 away from the embedding groove 11 passes through the bottom of the outer box 1 and is fixedly connected to the outer box 1. The mounting tube 8 is flush with the bottom of the outer box 1, and the mounting tube 8 is communicated with the outside. Four guide shells 6 are fixedly installed on the top of the guide plate 5. The four guide shells 6 are respectively located on the four sides of the multi-channel synchronous test recording device 3. The guide shell 6 is semicircular, and the arc surface of the guide shell 6 is provided with a plurality of air outlet holes 9. The diameters of the plurality of air outlet holes 9 gradually increase from the top center of the guide shell 6 to both sides. Four guide grooves 7 are provided inside the guide plate 5. The four guide grooves 7 are distributed in a circular array around the embedding groove 11 and are connected to the embedding groove 11. The end of the guide groove 7 away from the embedded groove 11 is connected to the guide shell 6 on the corresponding side. The fan 12 is fixedly installed inside the mounting pipe 8.

The inner wall of the mounting pipe 8 is provided with a first dust removal net 22. The first dust removal net 22 is located below the fan 12. The external air is sucked into the embedded groove 11 through the mounting pipe 8 through the fan 12. The first dust removal net 22 can filter dust and debris in the air to prevent these substances from entering the interior of the equipment, ensuring that the equipment operating environment is clean, reducing the risks that may be caused by dust accumulation inside the equipment, and improving the long-term stability and reliability of the equipment. The air inside the embedded groove 11 flows out from the four sides of the multi-channel synchronous test recording device 3 through the guide groove 7, the guide shell 6 and the air outlet 9, effectively taking away the heat generated by the equipment, playing a heat dissipation role, ensuring that it operates in a stable working environment, and avoiding failures and performance degradation caused by overheating. The design of the air outlet 9 allows the air to be evenly distributed to the four sides of the equipment, especially when the diameter of the air outlet 9 gradually increases, the distribution of the air flow becomes more uniform, ensuring that the air can fully contact the surface of the equipment and improve the heat dissipation effect. This uniform air distribution helps to avoid the occurrence of local overheating and improve the overall heat dissipation efficiency of the equipment. At the same time, when the gas circulates inside the guide groove 7, it can take away the multi-channel The heat transferred from the multi-channel synchronous test recording device 3 to the guide plate 5 is used to dissipate the heat of the multi-channel synchronous test recording device 3, thereby enhancing the heat dissipation effect. A temperature detection structure is arranged inside the multi-channel synchronous test recording device 3. When the temperature inside the multi-channel synchronous test recording device 3 exceeds a preset threshold value, the fourth electric telescopic rod 33 is extended to make the cover frame 4 move upward. Through the limiting of the guide ring 34 and the pushing of the baffle plate 36, the fixing rod 41 drives the plug 40 to be pushed upward, and the plug 40 is separated from the socket 10, ensuring that the device will not continue to operate at high temperature, preventing the device from shutting down due to overheating failure, reducing the aging of internal components due to high temperature, and improving the stability and long-term reliability of the device.

When not in use, the multiple groups of shielding plates 36 are moved to the lower ends of the multiple groups of guide rings 34 respectively by the fifth electric telescopic rod 44 to connect with the guide ring 34. When the multi-channel synchronous test recording device 3 is needed, the upper cover of the outer box 1 is opened, and then the plurality of shielding plates 36 are moved a certain distance by contracting the fifth electric telescopic rod 44, so that the shielding plates 36 no longer shield the guide ring 34, and then the plug 40 is inserted into the plug hole 10, so that the sliding bar 43 is inserted into the sliding groove, and at this time, the long arc surface of the shielding plate 36 contacts the outer surface of the fixing rod 41, and when the plurality of plugs 40 required for the test are inserted into the plug hole 10, the guide ring 34 is blocked. Afterwards, the fifth electric telescopic rod 44 is used to push the multiple groups of mounting shells 35 to move, and the baffle plates 36 corresponding to the plug holes 10 into which the plugs 40 are not inserted will block the guide rings 34 to prevent dust and other debris from falling in. The baffle plates 36 corresponding to the plug holes 10 into which the plugs 40 are inserted will be squeezed and moved by the fixing rod 41, so that the baffle plates 36 slide along the mounting shells 35. When the mounting shells 35 stop moving, the baffle plates 36 will be embedded in the locking grooves 42, which can limit the fixing rod 41 and prevent the plugs 40 from separating from the plug holes 10.

[0030] The multi-channel synchronous test recording device 3 is provided with a temperature detection structure, and four groups of support columns 2 are embedded in 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 recording device 3. The four groups of support columns 2 are arranged in contact with the four corners of the multi-channel synchronous test recording device 3. The lower end of the outer box 1 can be raised by the four groups of support columns 2 to facilitate air intake 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 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 embedded in the groove. 11 is fixedly connected to the inner wall. During use, the fan 12 is started. The external air can be sucked into the embedded groove 11 through the installation pipe 8 through the fan 12. When the air passes through the first dust removal net 22, the dust will be filtered. Four groups of guide grooves 7 are opened inside the guide plate 5. The four groups of guide grooves 7 are respectively connected to the embedded groove 11 and the four groups of guide shells 6. The outer surface of the guide shell 6 is provided with multiple groups of air outlet holes 9. The diameters of the multiple groups of air outlet holes 9 gradually increase from the center of the guide shell 6 to both sides. The air entering and exiting the embedded groove 11 through the fan 12 can pass through the guide shell 6, the guide shell 6, and the guide shell 6. The air flows out through the flow groove 7 and the air outlet 9. Since the larger the cross-section is, the greater the flow rate is at the same flow rate, the air outlet 9 can be arranged to disperse the air more evenly to different positions on one side of the multi-channel synchronous test recording device 3. The air can dissipate heat on the four sides of the multi-channel synchronous test recording device 3 by arranging multiple groups of guide shells 6. At the same time, when the gas circulates inside the guide groove 7, it can take away the heat transferred from the multi-channel synchronous test recording device 3 to the guide plate 5, so as to realize the heat dissipation of the multi-channel synchronous test recording device 3 and avoid its temperature being too high. When the temperature inside the synchronous test recording device 3 exceeds a preset threshold, the fourth electric telescopic rod 33 is extended for a distance. Since the fourth electric telescopic rod 33 is fixedly connected to one side of the cover frame 4 through the extension plate, the cover frame 4 can be moved upward by the fourth electric telescopic rod 33. Through the limiting of the guide ring 34 and the pushing of the shielding plate 36, the fixing rod 41 is pushed upward, so that the plug 40 can be pulled out from the inside of the plug hole 10 to avoid damage caused by continued temperature increase due to continuous use. The third spring 38 is used to pull the shielding plate 36 to reset.

[0031] When it is necessary to clean the first dust removal net 22, after unplugging the plug 40, close the upper cover of the outer box 1, seal the upper opening of the outer box 1, and then move the I-shaped block 17 upward through the first electric telescopic rod 16, so that the connecting square tube 15 is no longer closed, and then the fan 12 is reversed to blow air downward, so that the air circulates along the installation tube 8, the connecting square tube 15, the installation box 14, the connecting elbow 13 and the installation tube 8, and then the second electric telescopic rod 19 is continuously and rapidly extended and retracted. 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-bar 23, the knocking ring 25 will continuously hit the T-bar when the second electric telescopic rod 19 is continuously extended and retracted. The upper end of 23 makes the first dust removal net 22 vibrate, and 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. The first dust removal net 22 can be made to shake up and down while being vibrated by the first spring 21, so as to improve the dust removal effect. The second electric telescopic rod 19 does not directly contact the first dust removal net 22, and the possibility of the first dust removal net 22 being damaged by impact can be reduced. The fallen dust can enter the interior of the installation box 14 with the air, and then the dust will be blocked by the second dust removal net 26. After a period of time, the fan 12 is turned off. At this time, the dust gathers on the lower surface of the second dust removal net 26 and the interior of the installation box 14. First, a group of motors 30 are started to make the upper L-shaped rotating plate 31 move to The second dust collecting net 26 is rotated upward, during which the strip brush 32 will brush through the lower surface of the second dust collecting net 26 to brush off the dust, and then the other group of L-shaped rotating plates 31 will also rotate upward, and the two groups of motors 30 will make the two groups of L-shaped rotating plates 31 repeatedly brush at the lower end of the second dust collecting net 26. During this process, the third electric telescopic rod 29 is continuously extended and retracted to make it continuously tap the second dust collecting net 26, which can promote the falling of dust on the second dust collecting net 26 and the two groups of L-shaped rotating plates 31, and the fallen dust can fall to the lower end of the installation box 14 for collection, and then the two groups of L-shaped rotating plates 31 are reset. At this time, the collected dust is separated by the two groups of L-shaped rotating plates 31, and the lower end of the installation box 14 is set to a detachable structure for easy cleaning. The spring 27 can reset the second dust removal net 26, and then the I-shaped block 17 can be used to seal the inside of the connecting square tube 15 through the first electric telescopic rod 16, so as to clean the first dust removal net 22 and gather the cleaned dust to avoid it being sucked in again by the fan 12 when it is reused. The present invention can dissipate heat and prevent dust from the multi-channel synchronous test recording equipment 3 when it is in use. The setting of the baffle plate 36 can adapt to the use of different numbers of plugs 40, and can also separate the plug 40 from the socket 10 when the temperature is too high, thereby reducing the possibility of equipment damage. At the same time, it can realize automatic cleaning of the first dust removal net 22, which is not enough to avoid the cleaned dust being repeatedly sucked in, affecting the normal use of the first dust removal net 22.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
