Description
Technical Field
[0001] This utility model relates to the technical field of highway traffic monitoring equipment, and in particular to a highway monitoring signal transmission device. Background Technology
[0002] With the advancement of intelligent highway transportation construction, highway monitoring systems need to remotely transmit monitoring data through signal transmission devices. These devices are typically installed on poles along the highway. However, the existing installation structures for highway monitoring signal transmission devices have significant shortcomings: Firstly, most devices are directly fixed to the poles using welding or multiple sets of bolts, making the installation process cumbersome and prone to damaging the pole surface. Subsequent disassembly and maintenance are difficult, and the devices are not adaptable to the installation requirements of poles with different diameters. Secondly, the connection between the device and the installation structure is mostly a fixed, non-adjustable design, making it impossible to flexibly adjust the clamping position according to the actual size of the signal transmitter. Furthermore, the clamping parts lack effective anti-slip and vibration-damping structures, making the device prone to loosening due to vibrations generated by vehicles in the highway environment. This can affect the stability of signal transmission and may even cause the device to fall off, reducing the reliability of highway monitoring signal transmission. Therefore, it is necessary to design a highway monitoring signal transmission device to solve the above problems. Utility Model Content
[0003] The main objective of this invention is to provide a highway monitoring signal transmission device that can effectively solve the problems in the background art.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A highway monitoring signal transmission device includes a signal transmission unit. A cover plate is fixedly connected to the front end of the signal transmission unit by bolts. Multiple heat dissipation slots are opened at the left and right ends of the signal transmission unit. Two transmission antennas are fixedly connected to the upper rear end of the signal transmission unit, and the two transmission antennas are symmetrically distributed at the upper rear end of the signal transmission unit. An installation device is fixedly connected to the outside of the signal transmission unit. The installation device includes an upper crossbar, a lower crossbar, and a fixing bolt. The right ends of the upper and lower crossbars are fixedly connected to fixing components. The rear ends of the upper and lower crossbars are each provided with multiple screw holes. The rear ends of the upper and lower crossbars are fixedly connected to installation equipment components via fixing bolts. There are two installation equipment components, which are symmetrically distributed from left to right.
[0005] Preferably, the fixing component includes a side block, the front end of which has a groove, and the upper and lower walls of the groove are fixedly connected with retaining strips. The rear wall of the groove is fixedly connected with a clamping block one, and a clamping block two is engaged in the groove. The upper left and lower left ends of the clamping block two are both provided with retaining grooves. The opposing surfaces of the clamping block one and the clamping block two are both provided with clamping grooves, and rubber pads two are fixedly connected in each clamping groove. The front left and front right ends of the clamping block one are both provided with screws, and the outer surface of the screws is threaded with threaded sleeves. The side block is fixedly connected to the right ends of the upper crossbar and the lower crossbar, respectively.
[0006] Preferably, the clamping groove has an arc-shaped structure, the clamping block one and clamping block two have the same structure and are distributed opposite to each other, and the clamping grooves on clamping block one and clamping block two together form a complete circular clamping structure.
[0007] Preferably, the front end of the screw passes through the clamping block two and is fixed with a screw sleeve. The position and size of the slot are adapted to the position and size of the clip. The clamping block two is engaged with the clip through the slot and the clip, and the clamping block two is slidably engaged in the groove.
[0008] Preferably, the installation equipment assembly includes an upper mounting slider and a lower mounting slider. Both the upper and lower mounting sliders have through mounting grooves at their right ends. A fixing rod is fixedly connected to the middle of the front end of each of the upper and lower mounting sliders. A mounting frame is fixedly connected to the front end of each fixing rod. An anti-slip pad is fixedly connected to the inner wall of each mounting frame. Limit grooves are opened at the rear of the opposing surfaces of the two mounting frames. An adjusting rod is inserted through the rear of the opposing surfaces of the two mounting frames. The upper mounting slider is threadedly fixed to the outside of the upper crossbar via a fixing bolt, and the lower mounting slider is threadedly fixed to the outside of the lower crossbar via a fixing bolt.
[0009] Preferably, the adjusting rod is slidably connected to the limiting grooves of the two mounting frames.
[0010] Preferably, the anti-slip pad completely covers the inner wall of the mounting frame, and the thickness of the anti-slip pad is 1cm.
[0011] Preferably, the signal transmission device is electrically connected to external highway monitoring equipment via the monitoring connection cable on the left side.
[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. In this utility model, the fixing component in the installation device cooperates with the upper and lower crossbars. The side block of the fixing component slides with the slot of the clamping block two through the locking strip in the groove, so that the clamping block two can face the clamping block one. When the pole is placed in the clamping space between the two, the screw and the screw sleeve cooperate to drive the clamping block two to slide towards the clamping block one. The rubber pad two in the clamping groove achieves tight clamping of the pole. This cooperation relationship enables the fixing component to quickly, firmly and without damage install the highway pole through the sliding of the locking strip and the slot and the locking of the screw and the screw sleeve. It solves the problems of cumbersome installation, damage to the pole and poor adaptability of the existing device.
[0013] 2. In this utility model, the installation equipment component cooperates with the upper and lower crossbars. The upper and lower crossbars are engaged with the installation groove and screw hole of the installation equipment component through fixing bolts, thereby adjusting the position of the installation equipment component. The adjusting rod of the installation equipment component slides with the limiting groove of the installation clamping frame, allowing the spacing between the two installation clamping frames to be adjusted. At the same time, the anti-slip pad inside the installation clamping frame enhances the clamping stability. This cooperative relationship allows the installation equipment component to adjust its position through the engagement of fixing bolts with screw holes and grooves, and to adjust the clamping spacing through the engagement of adjusting rod with limiting grooves, thus stably clamping signal transmitters of different sizes. Furthermore, the anti-slip pad provides anti-slip and vibration-damping effects, solving the problems of non-adjustable connections, poor adaptability, and easy loosening due to vibration in existing devices.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0019] Please see Figure 1-4 This utility model provides a technical solution: A highway monitoring signal transmission device, such as Figure 1-4 As shown, the device includes a signal transmitter 1. A cover plate 5 is fixedly connected to the front end of the signal transmitter 1 by bolts. Multiple heat dissipation slots 4 are opened at the left and right ends of the signal transmitter 1. Two transmission antennas 3 are fixedly connected to the upper rear end of the signal transmitter 1, and the two transmission antennas 3 are symmetrically distributed at the upper rear end of the signal transmitter 1. An installation device 2 is fixedly connected to the outside of the signal transmitter 1.
[0020] Signal transmission device 1 is electrically connected to external highway monitoring equipment via the monitoring connection cable on the left.
[0021] Please see Figure 2 and Figure 3The installation device 2 includes an upper crossbar 21, a lower crossbar 25, and a fixing bolt 26. The right ends of both the upper and lower crossbars 21 and 25 are fixedly connected to fixing components 23. The rear ends of both the upper and lower crossbars 21 and 25 have multiple screw holes 24. The rear ends of the upper and lower crossbars 21 and 25 are fixedly connected to installation equipment components 22 via fixing bolts 26. Two installation equipment components 22 are provided, symmetrically distributed left and right. The fixing components 23 include side blocks 231. The front end of the side block 231 has a groove 2310. The upper and lower walls of the groove 2310 are fixedly connected to retaining strips 232. The rear wall of the groove 2310 is fixedly connected to a clamping block 233. A second clamping block 234 is clamped inside the groove 2310. The upper left and lower left ends of the second clamping block 234 have retaining grooves 239. The clamping blocks 233 and 234 are... Each side has a clamping groove 237, and a rubber pad 238 is fixedly connected inside each clamping groove 237. The left and right front ends of the clamping block 233 are each provided with a screw 235, and the outer surface of the screw 235 is threaded with a threaded sleeve 236. The side blocks 231 are fixedly connected to the right ends of the upper crossbar 21 and the lower crossbar 25, respectively. The clamping groove 237 has an arc-shaped structure. The clamping block 233 and the clamping block 234 have the same structure and are distributed opposite to each other. The clamping grooves 237 on the clamping block 233 and the clamping block 234 together form a complete circular clamping structure. The front end of the screw 235 passes through the clamping block 234 and is fixed with the threaded sleeve 236. The position and size of the slot 239 are adapted to the position and size of the clip 232. The clamping block 234 is engaged with the clip 232 through the slot 239, and the clamping block 234 is slidably engaged in the groove 2310.
[0022] Through the above scheme: the installation device 2 achieves core connection with the highway pole body through the fixing component 23 at the right end of its upper crossbar 21 and lower crossbar 25. The side block 231 of the fixing component 23, through the groove 2310 structure at its front end, utilizes the sliding cooperation between the upper and lower locking strips 232 in the groove and the corresponding locking groove 239 on the movable clamping block 234 to stably lock into the groove 2310 and face the fixed clamping block 1 233. When the highway pole body is placed in the circular clamping space formed by the two arc-shaped clamping grooves 237 between clamping block 1 233 and clamping block 234, tightening the screw sleeve 236 outside the screw 235 that passes through clamping block 234 and is connected to clamping block 1 233 will drive clamping block 234 to slide and close along the locking strip 232 towards clamping block 1 233. Thus, the rubber pad 238 in the clamping groove 237 tightly holds and protects the pole body. This design achieves quick, firm and non-destructive installation of the device on the pole body.
[0023] Please see Figure 2 and Figure 4The mounting equipment assembly 22 includes an upper mounting slider 221 and a lower mounting slider 227. Both the upper and lower mounting sliders 221 and 227 have through mounting grooves 222 at their right ends. A fixing rod 223 is fixedly connected to the middle of the front end of both the upper and lower mounting sliders 221 and 227. A mounting frame 224 is fixedly connected to the front end of each fixing rod 223. Anti-slip pads 228 are fixedly connected to the inner wall of each mounting frame 224. Limited openings are located at the rear of the opposing surfaces of the two mounting frames 224. The two mounting frames 224 have an adjusting rod 226 that is inserted and connected to the rear of their opposite sides in the slot 225. The upper mounting slider 221 is threadedly fixed to the outside of the upper crossbar 21 by a fixing bolt 26, and the lower mounting slider 227 is threadedly fixed to the outside of the lower crossbar 25 by a fixing bolt 26. The adjusting rod 226 is slidably connected to the limiting slots 225 of the two mounting frames 224. The anti-slip pad 228 completely covers the inner wall of the mounting frame 224 and has a thickness of 1cm.
[0024] Through the above scheme: the rear ends of the upper crossbar 21 and the lower crossbar 25 pass through the mounting groove 222 of the mounting equipment assembly 22 via fixing bolts 26 and are screwed into its multiple screw holes 24, fixing the two symmetrically distributed upper mounting sliders 221 and lower mounting sliders 227 respectively. Then, the mounting clamping frame 224 at the front end of the fixing rod 223 and its internal 1cm thick anti-slip pad 228 clamp the outer shell of the signal transmission device 1 from the left and right sides. The adjusting rod 226 connecting the two mounting clamping frames 224 can slide in the limiting groove 225, so that the clamping distance can be adjusted to adapt to different equipment sizes. Ultimately, it ensures that the entire signal transmission device 1 can work stably, anti-slip, and vibration-resistant continuously in complex highway environments, greatly improving the reliability of highway monitoring signal transmission and the convenience of installation and maintenance.
[0025] It should be noted that this utility model is a highway monitoring signal transmission device. The signal transmission device 1 is electrically connected to an external highway monitoring device via a monitoring connection cable on the left side to receive monitoring signals. Subsequently, the signals are processed internally and wirelessly transmitted via two transmission antennas 3 at the rear end to achieve remote data transmission. The heat generated during device operation is effectively dissipated through multiple heat dissipation slots 4 on the left and right sides to ensure stable operation. The cover plate 5 is fixed to the front end of the device with bolts for easy maintenance and sealing protection. The installation device 2 is used to fix the entire device to the highway pole. The upper crossbar 21 and lower crossbar 25 are clamped and fixed to the highway pole by the fixing component 23 at their right ends. The side block 231 of the fixing component 23 is recessed. The locking strip 232 in the groove 2310 slides into the locking groove 239 of the second clamping block 234, so that the first clamping block 233 and the second clamping block 234 use the clamping groove 237 and the second rubber pad 238 to hold the pole body, and lock it by the screw 235 and the screw sleeve 236. At the same time, the installation equipment assembly 22 at the rear end of the upper crossbar 21 and the lower crossbar 25 adjusts its position by the installation groove 222 of the upper installation slider 221 and the lower installation slider 227 and the fixing bolt 26 and the screw hole 24. This allows the installation clamping frame 224 at the front end of the fixing rod 223 to clamp the outside of the signal transmission equipment 1 by the anti-slip pad 228, and adjusts the clamping distance by sliding the adjusting rod 226 in the limiting groove 225. Finally, the device is firmly installed and stably operated on the highway pole.
[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
