Description

Technical Field

[0001] The invention belongs to the technical field of voltage pulse sources, and in particular relates to a voltage pulse source device. Background Art

[0002] A voltage pulse source is a device that can generate a voltage pulse signal. It can generate a high voltage pulse in a short time and is usually used in electronic testing, communications, medical equipment and other fields. The filter is the most basic microwave electronic device. It is a filter circuit composed of capacitors, inductors and resistors. The filter forms mainly include planar microstrip and cavity filters. The filter can effectively filter out a specific frequency point in the power line or frequencies outside the frequency point to obtain a power signal of a specific frequency, or eliminate a power signal after a specific frequency. Generally, the filter needs to be connected to a voltage pulse source when it is used for testing.

[0047] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] The present embodiment provides a voltage pulse source device, including: a protection box, a lifting assembly, a transmission assembly, a baffle and a cleaning assembly; the lifting assembly is arranged in the protection box, and is used to lift or lower the voltage pulse source in the protection box through vertical linear motion; the lifting assembly is transmission coupled to the transmission assembly; the baffle is arranged above the protection box, and the baffle is transmission coupled to the transmission assembly; the transmission assembly is used to convert the vertical linear motion of the lifting assembly into horizontal linear motion of the baffle, so that the baffle opens or closes the protection box; the cleaning assembly is arranged in the protection box, and is used to clean the voltage pulse source during the lifting or lowering process.

[0049] In this embodiment, the vertical linear motion of the voltage pulse source is realized inside the protection box by a lifting component (such as an electric telescopic rod). The lifting component is coupled with a transmission component (such as a gear, a rack, a screw, etc.). When the lifting component moves up and down, the transmission component converts this vertical motion into a rotational motion, and further converts the rotational motion into a horizontal linear motion of the baffle through a second transmission component, so that the baffle opens or closes the protection box. At the same time, when the voltage pulse source moves up and down, a cleaning component (such as a cleaning brush) will clean the voltage pulse source to remove dust or other impurities on the surface.

[0050] This embodiment provides a voltage pulse source device, which realizes safe lifting and automatic cleaning of the voltage pulse source through the structural design of the protection box, lifting assembly, transmission assembly, baffle and cleaning assembly, thereby improving the reliability and service life of the equipment.

[0051] In one embodiment, the transmission assembly includes: a first transmission assembly and a second transmission assembly; the input end of the first transmission assembly is transmission coupled to the lifting assembly or the voltage pulse source, the output end is transmission coupled to the input end of the second transmission assembly, and the output end of the second transmission assembly is transmission coupled to the baffle; the first transmission assembly is used to convert the vertical linear motion of the lifting assembly into rotational motion, and transmit the rotational motion to the second transmission assembly; the second transmission assembly is used to convert the rotational motion into horizontal linear motion, and drive the baffle to slide above the protective box to open or close the protective box.

[0052] In this embodiment, the transmission assembly is composed of a first transmission assembly and a second transmission assembly. When the lifting assembly performs vertical linear motion, the first transmission assembly (such as a rack and gear combination) converts the vertical motion into a rotational motion. Then, the first transmission assembly transmits the rotational motion to the second transmission assembly (such as a screw and a screw sleeve) through a transmission connection (such as a pulley system). The second transmission assembly then converts the rotational motion into horizontal linear motion, and drives the baffle to slide above the protection box through the first connecting rod and other structures, thereby realizing the opening or closing of the protection box.

[0053] This embodiment converts vertical linear motion into horizontal linear motion through a transmission component, thereby realizing automatic opening and closing of the baffle, reducing the need for manual operation and improving work efficiency.

[0054] In one embodiment, the lifting assembly includes: a base plate and an electric telescopic rod; the electric telescopic rod is vertically arranged at the bottom of the protective box, and the telescopic end of the electric telescopic rod is arranged inside the protective box; the base plate is fixedly connected to the telescopic end of the electric telescopic rod, and the base plate is used to fix the voltage pulse source.

[0055] In this embodiment, the lifting assembly is mainly composed of a base plate and an electric telescopic rod. The electric telescopic rod is vertically installed at the bottom of the protection box, and its telescopic end is located inside the protection box and fixedly connected to the base plate. The base plate is used to fix the voltage pulse source. When the voltage pulse source needs to be raised or lowered, the electric telescopic rod is extended or shortened, thereby driving the base plate and the voltage pulse source thereon to perform vertical linear motion.

[0056] This embodiment adopts an electric telescopic rod as a power source, which realizes the automatic lifting and lowering of the voltage pulse source without manual handling, thereby improving operational efficiency and convenience.

[0057] In one embodiment, the first transmission assembly includes: a rack plate, a gear and a rotating rod; the rack plate is fixed to one side of the base plate or the voltage pulse source; the gear is meshingly connected to the rack plate; the rotating rod is rotatably connected to the side wall of the protection box through a bearing, and one end of the rotating rod is fixed to the center of the gear, and the other end extends out of the side wall of the protection box and is transmission coupled to the second transmission assembly through a transmission connector.

[0058] In this embodiment, the rack plate is fixed to one side of the base plate or the voltage pulse source, and as the base plate or the voltage pulse source moves vertically and linearly, the rack plate will also move up and down. The gear is meshed with the rack plate. When the rack plate moves up and down, it drives the gear meshed with it to rotate. The rotating rod is rotatably connected to the side wall of the protection box through a bearing, one end of which is fixed to the center of the gear, and the other end extends out of the side wall of the protection box. When the gear rotates, it drives the rotating rod to rotate. The other end of the rotating rod is coupled to the second transmission assembly through a transmission connector (such as a pulley, chain, etc.), and the rotational motion is transmitted to the second transmission assembly, thereby completing the subsequent motion conversion task.

[0059] This embodiment can effectively convert vertical linear motion into rotational motion through the meshing of the rack plate and the gear, thereby ensuring the accuracy and reliability of the motion conversion.

[0060] In one embodiment, the second transmission assembly includes: a screw, a sleeve and a first connecting rod; the screw is rotatably connected to the side wall of the protection box through a bearing, and the screw is transmission coupled to the first transmission assembly through a transmission connector; the sleeve is threadedly connected to the screw; one end of the first connecting rod is fixedly connected to the sleeve, and the other end is fixedly connected to the baffle.

[0061] In this embodiment, the screw is rotatably connected to the side wall of the protection box through a bearing, and is coupled to the first transmission assembly through a transmission connector (such as a pulley, a chain, etc.). When the rotational motion transmitted by the first transmission assembly reaches the screw, the screw begins to rotate. The screw sleeve is threadedly connected to the screw, and when the screw rotates, the screw sleeve moves on the screw along its axial direction (i.e., horizontal direction). One end of the first connecting rod is fixedly connected to the screw sleeve, and the other end is fixedly connected to the baffle. When the screw sleeve moves on the screw, the baffle is driven to slide in the horizontal direction by the first connecting rod, thereby realizing the opening or closing of the baffle.

[0062] In this embodiment, the horizontal movement distance of the baffle can be accurately controlled by the threaded cooperation between the screw rod and the screw sleeve, thereby ensuring the accuracy of opening or closing the baffle.

[0063] In one embodiment, a first slide groove is further provided on the side wall of the protection box, a sliding block is provided below the baffle plate, and the baffle plate is slidably connected to the first slide groove via the sliding block.

[0064] In this embodiment, the baffle moves along the direction of the slide groove (usually horizontally). When the second transmission component (such as the screw and the screw sleeve) drives the first connecting rod to move, the first connecting rod drives the baffle to slide along the direction of the slide groove. In this way, the baffle can smoothly open or close the opening of the protection box. The design of the slider and the slide groove not only provides a guiding function, but also plays a role in supporting the baffle, ensuring that the baffle will not deflect or jam during the movement.

[0065] In one embodiment, a mounting plate is further provided on the side wall of the protection box at a position corresponding to the screw rod, the mounting plate is provided with a second sliding groove, the screw sleeve is provided with a sliding rod, and the screw sleeve is slidably connected to the second sliding groove via the sliding rod.

[0066] In this embodiment, a slide bar is provided on the screw sleeve, and the slide bar cooperates with the second slide groove on the mounting plate to form a sliding connection. This enables the screw sleeve to move along the screw rod while the slide bar slides in the second slide groove, thereby ensuring the smooth movement of the screw sleeve.

[0067] In one embodiment, the transmission connection includes: a first transmission wheel, a belt and a second transmission wheel; the first transmission wheel is connected to the first transmission assembly, the second transmission wheel is connected to the second transmission assembly, and the belt is connected between the first transmission wheel and the second transmission wheel.

[0068] In this embodiment, the first transmission wheel is connected to the first transmission component (such as a rotating rod). When the first transmission component generates a rotational motion, the first transmission wheel rotates accordingly. The belt passes around the first transmission wheel and the second transmission wheel to transmit the rotational motion. When the first transmission wheel rotates, the second transmission wheel is driven to rotate synchronously through the belt. The second transmission wheel is connected to the second transmission component (such as a screw). When the second transmission wheel rotates, it drives the second transmission component to perform a corresponding motion conversion (such as the rotation of the screw). Through the tensioning effect of the belt, the rotational motion can be efficiently transmitted between the first transmission wheel and the second transmission wheel to ensure the continuity and stability of the motion.

[0069] In one embodiment, the protection box further includes: a fan and an exhaust port below; the fan and the exhaust port are arranged below two opposite side walls of the protection box.

[0070] In this embodiment, a fan is installed under one side wall of the protection box to generate airflow and guide air into the protection box. The temperature inside the protection box is reduced through the suction of the fan and the discharge of the air through the outlet, and dust or other impurities that may exist can be discharged to keep the interior clean and dry.

[0071] In one embodiment, the cleaning assembly includes: a cleaning frame and a cleaning brush; the cleaning frame is arranged circumferentially along the inner wall of the protection box; and the cleaning brush array is arranged in the cleaning frame.

[0072] In this embodiment, the cleaning frame is arranged along the inner wall of the protection box, that is, the cleaning frame is arranged around the inner wall of the protection box. The cleaning brush array is arranged in the cleaning frame, and the cleaning brush is perpendicular to the cleaning frame. When the voltage pulse source moves up and down in the protection box, the cleaning brush will contact the surface of the voltage pulse source and clean it.

[0081] Specifically, a disc 16 is fixedly connected to one side of the screw rod 11 away from the second transmission wheel 12 , so that the screw sleeve 17 on the screw rod 11 can be conveniently limited and protected by the disc 16 .

[0084] When in use, when it is necessary to connect the filter to the voltage pulse source for testing, first support the protection box 1 stably with the legs, then start the electric telescopic rod 4 and the drive motor 25 respectively through the power supply, the output end of the electric telescopic rod 4 will push the bottom plate 5, the bottom plate 5 will be pushed by the force to push the voltage pulser 6, when the voltage pulser 6 rises inside the protection box 1, it will drive the rack plate 7 to rise synchronously, the rack plate 7 moves at this time to mesh and drive the gear 9, the gear 9 is forced at this time to drive the rotating rod 8 to rotate through the bearing, and when the rotating rod 8 rotates, it will synchronously drive the protection box 1 to move.
