Description

Technical Field

[0001] This utility model relates to the field of railway catenary maintenance technology, specifically an image acquisition box based on a catenary temperature detection system. Background Technology

[0002] Currently, the railway power supply industry primarily uses a 6C inspection system to assess the quality of overhead contact line equipment. The 2C inspection device (overhead contact line safety inspection device) is a temporary device installed on operating high-speed trains to inspect the condition of the overhead contact line, statistically analyze the technical condition of the contact suspension components, and guide maintenance. The 4C inspection device (overhead contact line suspension condition detection and monitoring device) is installed on overhead contact line work vehicles or special vehicles. It periodically performs high-resolution imaging inspections of components of the overhead contact line suspension system and the geometric parameters of the contact line, especially components in the cantilever area. Based on the automatic identification and analysis of the inspection data, it generates maintenance suggestions to guide overhead contact line maintenance.

[0003] Based on the above, the inventors have discovered the following problems: most current image acquisition boxes are fixedly installed on trains, and the monitoring probes installed on the image acquisition boxes can only provide a limited field of view. Their angles are inconvenient to adjust, which makes it impossible for the monitoring probes to acquire images of the contact wire from different angles, thereby reducing the image acquisition efficiency.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an image acquisition box based on the contact wire temperature detection system, in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this invention is to provide an image acquisition box based on a contact wire temperature detection system to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] An image acquisition box based on a contact wire temperature detection system includes an acquisition box body and a position adjustment mechanism. The acquisition box body includes a box body with a door on the top surface. A mounting frame is installed on the upper end of the door. Mounting cavities are opened on both sides of the mounting frame. Connecting blocks are rotatably connected inside the two mounting cavities. A visible light camera and an infrared camera are respectively mounted on opposite sides of the two connecting blocks. Motors are installed on both sides of the back of the mounting frame, and the output ends of the two motors are respectively connected to the two connecting blocks for transmission.

[0008] Furthermore, a pair of hinge seats are installed on the outer side wall of the box, and a hinge block is hinged inside each pair of hinge seats. One side of each pair of hinge blocks is connected to the outer side wall of the box door.

[0009] Furthermore, a data acquisition module is installed inside the housing, and an operation terminal is installed on one side of the data acquisition module inside the housing. A wireless communication module is installed on the other side of the operation terminal inside the housing. The input and output terminals of the visible light camera and the infrared camera are both connected to the input and output terminals of the data acquisition module. The data acquisition module, the operation terminal, and the wireless communication module are electrically connected by wires.

[0010] The beneficial effect of adopting the above-mentioned further solution is that, through the combined use of the data acquisition module and the visible light camera and infrared camera, the data acquisition module can easily collect data from the visible light camera and infrared camera, transmit it to the operation terminal for data processing and analysis, and then the wireless communication module transmits the processed data to the monitoring platform.

[0011] Furthermore, the bottom of the housing is provided with a position adjustment mechanism, which includes a connecting seat and a support column. The connecting seat is installed at the bottom of the housing. Sliding grooves are provided on both sides of the inner wall of the support column. A telescopic rod is slidably connected between a pair of sliding grooves. One end of the telescopic rod extends through the support column to the outside and is mounted on a mounting seat. A smooth rod is installed inside one end of the mounting seat. Both ends of the smooth rod extend through the mounting seat to the outside and are respectively connected to the inner side wall of the connecting seat. A screw is rotatably connected to one side of the inner wall of the support column. One end of the screw extends through the bottom end of the telescopic rod to the inside and is threadedly connected to the telescopic rod.

[0012] The beneficial effect of adopting the above-mentioned further solution is that by setting a screw, when the screw rotates, the telescopic rod connected to the external thread of the screw moves horizontally under the sliding action with the slide groove, thereby moving the connecting seat and adjusting the position of the box, thus avoiding the fixed position of the box causing the position of the box to be unable to be adjusted according to actual needs.

[0013] Furthermore, an installation box is installed on the outside of one end of the support column away from the mounting base, and an opening is provided on the outside of the support column at the location of the installation box. The support column and the installation box are connected through the opening. A first gear is sleeved on the outside of the end of the screw away from the mounting base. A rotating shaft is rotatably connected inside the installation box. A second gear is sleeved on the outside of the rotating shaft. The first gear and the second gear mesh with each other.

[0014] The beneficial effect of adopting the above-mentioned further solution is that, through the cooperation of the first gear and the second gear, when the shaft rotates, it drives the second gear to rotate, and the second gear drives the first gear to rotate, thereby realizing the rotation of the screw.

[0015] Furthermore, a worm gear is fitted on the outside of the rotating shaft on one side of the second gear. The worm gear is connected to a worm, and the two ends of the worm are respectively connected to the inner wall of the mounting box through bearings. One end of the worm extends through the mounting box to the outside and is fitted with a knob.

[0016] The beneficial effect of adopting the above-mentioned further solution is that, through the coordinated use of the knob, worm gear and worm wheel, when the knob is turned, the worm gear is easily rotated, which in turn drives the worm wheel to rotate, thereby realizing the rotation of the shaft.

[0017] Furthermore, a support base is installed on the outside of one end of the support column, a support rod is installed on one end of the support base, a reinforcing seat is fitted on the outside of the bottom end of the support rod, and screw holes are opened at the four corners of the reinforcing seat.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the overall support strength of the position adjustment mechanism is improved by using the support base, support rod and reinforcing base together. At the same time, by opening screw holes at the four corners of the reinforcing base, it is convenient to install the image acquisition box in the designated position.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This image acquisition box based on the contact wire temperature detection system, by installing two motors, allows the two connecting blocks to rotate separately when the two motors are started, thereby adjusting the angles of the visible light camera and the infrared camera respectively. This enables omnidirectional image acquisition of the contact wire from different angles, improving image acquisition efficiency. Through the combined use of the visible light camera and the infrared camera, the visible light camera can capture rich color and detail information, while the infrared camera detects the infrared radiation emitted by the object and converts it into temperature information, thus achieving temperature measurement of the contact wire. At the same time, the visible light camera can provide clear images in well-lit environments, while the infrared camera can provide clear images in low-light environments, thereby improving image acquisition efficiency.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-5This utility model provides a technical solution: a position adjustment mechanism 200 is provided at the bottom of the housing 1001. The position adjustment mechanism 200 includes a connecting seat 2001 and a support column 2002. The connecting seat 2001 is installed at the bottom of the housing 1001. Sliding grooves 2003 are provided on both sides of the inner wall of the support column 2002. A telescopic rod 2004 is slidably connected between a pair of sliding grooves 2003. One end of the telescopic rod 2004 extends through the support column 2002 to the outside and is mounted on a mounting seat 2006. A smooth rod 2007 is installed inside one end of the mounting seat 2006. Both ends of the smooth rod 2007 extend through the mounting seat 2006 to the outside and are respectively connected to the inner side wall of the connecting seat 2001. A screw 2005 is rotatably connected to one side of the inner wall of the column 2002. One end of the screw 2005 extends through the bottom end of the telescopic rod 2004 and is threadedly connected to the telescopic rod 2004. A mounting box 2009 is installed on the outer side of one end of the support column 2002, away from the mounting base 2006. An opening is provided on the outer side of the support column 2002 at the mounting box 2009, through which the support column 2002 and the mounting box 2009 communicate. A first gear 2008 is sleeved on the outer side of the screw 2005 at the end away from the mounting base 2006. A rotating shaft 2010 is rotatably connected inside the mounting box 2009. A second gear 2011 is sleeved on the outer side of the rotating shaft 2010. The first gear 2008... The second gear 2011 meshes with the shaft 2010. A worm gear 2012 is fitted onto the outside of the shaft 2010, located on one side of the second gear 2011. The worm gear 2012 is connected to a worm 2013. Both ends of the worm 2013 are connected to the inner wall of the mounting box 2009 via bearings. One end of the worm 2013 extends through the mounting box 2009 to the outside and is fitted with a knob 2014. A support base 2015 is mounted on the outside of one end of the support column 2002. A support rod 2016 is mounted on the bottom end of the support base 2015. A reinforcing seat 2017 is fitted on the outside of one end of the support rod 2016. Screw holes are provided at the four corners of the reinforcing seat 2017. When the operator rotates the knob 2014, the knob 2... 014 drives the worm gear 2013 to rotate, which in turn drives the worm wheel 2012 to rotate, thus rotating the shaft 2010. When the shaft 2010 rotates, it drives the second gear 2011 to rotate, which in turn drives the first gear 2008 to rotate, thereby rotating the screw 2005. This causes the telescopic rod 2004, which is externally threaded to the screw 2005, to move horizontally under the sliding action of the slide groove 2003, thereby adjusting the position of the housing 1001. This prevents the housing 1001 from being fixed in position and thus unable to be adjusted according to actual needs. At the same time, by opening screw holes at the four corners of the reinforcing seat 2017, the image acquisition box is installed in the designated position.

[0032] Specifically, the working principle of this image acquisition box based on the contact wire temperature detection system is as follows: During use, the reinforcing seat 2017 is installed in the designated position using bolts. The operator rotates the knob 2014, which drives the worm gear 2013 to rotate. The worm gear 2013 drives the worm wheel 2012 to rotate, thus rotating the shaft 2010. This drives the second gear 2011 to rotate, which in turn drives the first gear 2008 to rotate, thereby rotating the screw 2005. This causes the telescopic rod 2004, connected to the external thread of the screw 2005, to move horizontally under the sliding action of the slide groove 2003. The position of the box 1001 can then be adjusted according to the shooting requirements, facilitating comprehensive image acquisition of different positions on the contact wire after the train stops. This expands the contact wire detection area and prevents the box 1001 from being fixed in position, which would hinder image acquisition. Then, when the two motors are started... At time 1007, the two connecting blocks 1004 are rotated separately to adjust the angles of the visible light camera 1005 and the infrared camera 1006, facilitating omnidirectional shooting and image acquisition of the contact network from different angles. The visible light camera 1005 can capture rich color and detail information, while the infrared camera 1006 measures the temperature of the object by detecting the infrared radiation emitted by the object and converting it into temperature information. The visible light camera 1005 provides clear images in well-lit environments, while the infrared camera 1006 provides clear images in low-light environments, thereby improving image acquisition efficiency. Then, the data acquisition module 1010 acquires the images captured by the visible light camera 1005 and the infrared camera 1006 and transmits them to the operation terminal 1011 for data processing and analysis. Finally, the wireless communication module 1012 transmits the processed data to the monitoring platform.
