Description

Technical Field

[0001] This utility model relates to the field of warning device technology, specifically a wireless transmission warning device for high-speed trains. Background Technology

[0002] This shunting safety warning device for high-speed trains is designed to alert personnel to safety precautions and prevent accidents. It utilizes infrared sensors or other sensors installed at key locations such as train cars and work areas. When personnel or objects enter the warning range, the system automatically detects and triggers an audible and visual alarm or other warning device, alerting personnel to immediately leave the danger zone. This effectively prevents personnel from accidentally entering hazardous areas, reduces the likelihood of accidents, and improves the safety and efficiency of shunting operations.

[0003] Utility model patent CN222619219U discloses a safety warning device for shunting of high-speed trains. This utility model includes a passageway, a valve located on the upper right side of the passageway, and a fence located on the lower left side of the valve. A warning box is fixedly connected to the upper left side of the valve, and a pit is located on the lower right side of the valve. An infrared ray device is located below the warning box, and horn-shaped openings are located on both the front and rear sides of the warning box. A warning light box is located on the front side of the fence. The system can automatically monitor key areas and immediately take warning measures upon detecting abnormalities, promptly reminding personnel to stay away from dangerous areas, effectively reducing the possibility of accidents and improving workplace safety. The system's automated monitoring and warning functions reduce reliance on manual monitoring, lowering labor costs for staff and reducing their workload, allowing them to devote more energy to other tasks.

[0004] While the aforementioned utility model can immediately take warning measures in case of abnormal situations, effectively reducing the possibility of accidents, it is still necessary to notify external personnel and the dispatch center while the warning box is issuing an alarm. This notification involves transmitting a signal to the outside world via an antenna. Therefore, we propose a wireless transmission warning device for high-speed trains. Utility Model Content

[0005] This utility model provides a wireless transmission warning device for high-speed trains to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A wireless transmission warning device for high-speed trains includes a warning box, a signal box at the top of the warning box, a cover mechanism at the middle of the upper surface of the signal box, a partition plate at the middle of the interior of the signal box, and a control mechanism installed on the partition plate.

[0008] The control mechanism includes two sprockets rotatably connected to the upper surface of the partition plate and a chain wound around the outside of the two sprockets. A motor is fixedly installed on the lower surface of the partition plate at the lower end of the left sprocket. A rotating wheel is fixedly installed on the upper surface of each sprocket. A rubber belt is sleeved on the outer end of the two rotating wheels. Several mounting mechanisms are fixedly installed inside the rubber belt. An electric push rod is provided at the lower end of one of the mounting mechanisms.

[0009] As a preferred technical solution, there are two rubber belts, namely an inner belt and an outer belt. The inner surface of the inner belt is in close contact with the outer surface of the rotating wheel. The inner belt and the outer belt are connected by the mounting mechanism. The motor is a servo motor.

[0010] This setup, controlled by a servo motor, ensures precise control of the sprocket, allowing the mounting mechanism to move the antenna to the appropriate position.

[0011] As a preferred technical solution, the electric push rod is installed on the lower surface of the partition plate. After the electric push rod is activated, the push rod of the electric push rod passes through the partition plate and enters the installation mechanism.

[0012] In this configuration, the electric push rod is fixedly installed on the lower side of the partition plate. The push rod pushes out the extension rod located inside the closed sleeve, thereby sending the antenna out of the hole covered by the upper cover mechanism, which facilitates the antenna signal transmission.

[0013] As a preferred technical solution, the installation mechanism includes a connecting base and a closed sleeve fixedly connected to the upper end of the connecting base. The upper surface of the connecting base has a through hole, the lower surface of the closed sleeve has a through hole, an extension rod is slidably connected inside the closed sleeve, and an antenna is provided at the top of the extension rod.

[0014] As a preferred technical solution, the connecting base is made of rubber, the sealing sleeve is made of copper, and the antennas are a 2.4GHz antenna, a 5GHz antenna, and a sub-1GHz antenna.

[0015] These two settings ensure that the extension rod can be used in conjunction with the electric push rod to push different types of antennas out of the signal box, and that the type of antenna can be selected appropriately according to different usage scenarios.

[0016] As a preferred technical solution, the diameter of the through hole is equal to the inner diameter of the closed sleeve, the diameter of the through hole is smaller than the diameter of the through hole, and the diameter of the through hole is equal to the push rod diameter of the electric push rod.

[0017] This setting ensures that the actuator rod of the electric linear actuator can pass through the through hole and contact the extension rod.

[0018] As a preferred technical solution, the upper cover mechanism includes a fixed frame welded to the upper surface of the signal box, a rotating shaft welded to the left end inside the fixed frame, a rotating plate rotatably connected to the outside of the rotating shaft, and a cover plate welded to the outer end of the rotating plate.

[0019] As a preferred technical solution, the upper surface of the signal box has a hole for the antenna to extend out. The diameter of the hole is smaller than that of the cover plate. A magnet is embedded inside the cover plate, and a sealing ring is provided at the contact point between the cover plate and the upper surface of the signal box.

[0020] These two features ensure that the antenna can pass smoothly through the signal box while allowing the top cover mechanism to cover the opening at other times and prevent rainwater from seeping into the signal box.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. It can switch antenna frequency bands according to communication needs, and select the type of antenna to use as needed according to different usage scenarios to ensure the accuracy of the transmitted signal.

[0023] 2. Integrate antennas of multiple frequency bands into one unit, and maintain the best spatial isolation between antennas of each frequency band through a reasonable three-dimensional layout. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0033] Please see Figures 1-5 This embodiment provides a technical solution:

[0034] The wireless transmission warning device for high-speed trains includes a warning box 100, a signal box 200 at the top of the warning box 100, a cover mechanism 210 at the middle position of the upper surface of the signal box 200, a partition plate 230 at the middle position inside the signal box 200, and a control mechanism 220 installed on the partition plate 230.

[0035] The control mechanism 220 includes two sprockets 223 rotatably connected to the upper surface of the partition plate 230 and a chain 222 wound around the outside of the two sprockets 223. A motor 221 is fixedly installed on the lower surface of the partition plate 230 at the lower end of the left sprocket 223. A rotating wheel 224 is fixedly installed on the upper surface of each sprocket 223. A rubber belt 225 is sleeved on the outer end of the two rotating wheels 224. Several mounting mechanisms 226 are fixedly installed inside the rubber belt 225. An electric push rod 227 is provided at the lower end of one of the mounting mechanisms 226. Through the above mechanism, while the warning box 100 transmits the warning signal, the signal box 200 can continue to transmit the warning signal to the outside world and to the control center, etc., to ensure that a rapid response can be made in case of an accident. By reasonably selecting different types of antennas, the stability and accuracy of signal transmission can be improved.

[0036] Furthermore, such as Figure 4As shown, there are two rubber belts 225, which are divided into an inner belt and an outer belt. The inner surface of the inner belt is in close contact with the outer surface of the rotating wheel 224. The inner belt and the outer belt are connected by the mounting mechanism 226. The motor 221 is a servo motor. The servo motor can accurately control the number of rotations, which makes it easy to control the rotation of the sprocket 223 and thus control the position of the mounting mechanism 226.

[0037] Furthermore, such as Figure 4 As shown, the electric push rod 227 is installed on the lower surface of the partition plate 230. After the electric push rod 227 is started, the push rod of the electric push rod 227 passes through the partition plate 230 and enters the mounting mechanism 226. The electric push rod 227 pushes out the antenna 2265 in the mounting mechanism 226, which has reached the appropriate position.

[0038] In this embodiment, as Figure 5 As shown, the mounting mechanism 226 includes a connecting base 2261 and a closed sleeve 2263 fixedly connected to the upper end of the connecting base 2261. A through hole 2262 is formed on the upper surface of the connecting base 2261, and a through hole 2266 is formed on the lower surface of the closed sleeve 2263. An extension rod 2264 is slidably connected inside the closed sleeve 2263, and an antenna 2265 is mounted at the top of the extension rod 2264. The connecting base 2261 is made of rubber and can deform slightly with the movement of the inner and outer rubber strips 225. The closed sleeve 2263 is made of copper and provides good signal shielding properties, preventing external electromagnetic signals from affecting the use of the antenna 2265. The antennas 2265 are a 2.4GHz antenna, a 5GHz antenna, and a sub-1GHz antenna. The 2.4GHz antenna is suitable for scenarios with moderate requirements for transmission rate and distance, and good compatibility. The sub-1GHz... The antenna's strong diffraction capability, long transmission distance, and low power consumption enable it to perform communication tasks. The 5GHz antenna utilizes the high bandwidth characteristics brought by its high frequency band to achieve fast data transmission. In long-distance, low-power communication scenarios, it can report status information to the EMU and remote dispatch center, and transmit low-frequency remote data. Different types of antennas 2265 have different lengths, and the length of the extension rod 2264 is adjusted according to the length of the antenna 2265 to ensure that the length of the extension rod 2264 plus the length of the antenna 2265 is less than or equal to the length of the enclosure 2263.

[0039] In this embodiment, as Figure 5 As shown, the diameter of the through hole 2262 is equal to the inner diameter of the closed sleeve 2263, the diameter of the through hole 2266 is smaller than the diameter of the through hole 2262, and the diameter of the through hole 2266 is equal to the push rod diameter of the electric push rod 227, ensuring that the electric push rod 227 can pass through the through hole 2266 and contact the extension rod 2264.

[0040] In this embodiment, as Figure 2As shown, the upper cover mechanism 210 includes a fixed frame 211 welded to the upper surface of the signal box 200, a rotating shaft 212 welded to the left end of the inside of the fixed frame 211, a rotating plate 213 rotatably connected to the outside of the rotating shaft 212, and a cover plate 214 welded to the outer end of the rotating plate 213. The upper surface of the signal box 200 has a hole for the antenna 2265 to extend out. The diameter of the hole is smaller than that of the cover plate 214. A magnet is embedded inside the cover plate 214. A sealing ring is provided at the contact point between the cover plate 214 and the upper surface of the signal box 200. In use, the extension rod 2264 and the antenna 2265 pushed by the electric push rod 227 can easily push open the cover plate 214 to send out the antenna 2265. After use, the electric push rod 227 retracts and drives the extension rod 2264 to retract and return to the closed sleeve 2263. The cover plate 214 covers the hole again under the action of gravity.

[0041] It is worth noting that the structure and working principle of the motor 221 and electric push rod 227 involved in this embodiment are as known to those skilled in the art, and will not be described in detail here.

[0042] In the specific use of the EMU wireless transmission warning device in this embodiment, when the warning box 100 detects a situation requiring a warning, the signal box 200 selects an antenna to transmit a signal to the outside world as needed, depending on the urgency of the situation. The 2.4GHz antenna is suitable for scenarios with moderate requirements for transmission rate and distance, and good compatibility. The sub-1GHz antenna has the characteristics of strong diffraction capability, long transmission distance, and low power consumption to complete the communication task. The 5GHz antenna utilizes the high bandwidth characteristics brought by its high frequency band to achieve fast data transmission. In long-distance, low-power communication scenarios, it can report status information to the EMU and the remote dispatch center, and transmit low-frequency remote data.

[0043] After selecting a suitable antenna, start motor 221. The servo motor 221 controls the rotation of sprocket 223, which in turn causes the rotating wheel 224 on sprocket 223 to rotate. The rotation of the rotating wheel 224 causes the rubber belt 225 to move, thereby controlling the mounting mechanism 226. The mounting mechanism 226, which contains the appropriate type of antenna 2265, is moved to the upper side of the electric push rod 227. Then, turn off motor 221 and start electric push rod 227. The electric push rod 227 pushes through the through hole 2262 and through hole 2266 into the closed sleeve 2263, pushing the extension rod 2264 upward. The extension rod 2264, carrying the antenna 2265, lifts the cover plate 214, allowing the antenna 2265 to leave the signal box 200 and be used outside to transmit signals to the outside as needed.

[0044] 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 preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
