Abstract
Description
Technical Field
[0001] This utility model relates to the field of road cleaning technology, specifically a road washing vehicle. Background Technology
[0002] Traditional road washing equipment (such as cleaning trucks and water sprinkler trucks) relies directly on the vehicle's engine for power. The washing capacity (washing water flow and pressure) is strongly correlated with engine speed and cannot be independently controlled. This means the width of the washing water can only be controlled through gearbox gears and throttle, not by balancing the width of the washing water with the vehicle's speed. This results in a trade-off between work quality and efficiency. Specifically, when the road widens and the washing width needs to be increased, the engine speed must be increased to increase water pressure, causing the vehicle speed to exceed the optimal operating speed (usually 15-20 km / h). Excessive speed affects the washing effect (insufficient washing time per unit area), leading to a decrease in road cleanliness. Conversely, when the road narrows and the washing width needs to be reduced, the engine speed must be decreased to reduce water pressure, resulting in slower vehicle speed and impacting the efficiency of the road washing operation.
[0003] Therefore, this utility model proposes a road washing vehicle to solve the above problems. Utility Model Content

Detailed Implementation
[0024] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0025] Please see Figure 1 A road washing vehicle includes a washing vehicle body 1, the washing vehicle body 1 including a washing mechanism for washing the road surface, and the washing vehicle body 1 is independently provided with a washing power system for providing driving energy to the washing mechanism and a control unit for controlling the energy output of the washing power system.
[0026] It should be noted that the flushing mechanism includes a water spray pipe, a water supply pipeline, and a corresponding pump set for pumping water. The flushing power system refers to the system that provides driving energy to the pump set. If the pump set is an electric hydraulic pump set, the flushing power system is set up to provide electrical energy to the motor in the electric hydraulic pump set, including the main power supply (lithium battery, battery, etc.), power conversion and regulation device, power distribution and protection device, etc. If the pump set is a diesel engine driven pump set, the flushing power system is set up to be an independently set diesel engine power system, including the diesel engine, oil pipeline, etc.
[0027] The vehicle is powered by its own engine, while the washing mechanism is powered by an independently set washing power system. The two systems are controlled independently and do not restrict each other, so the vehicle speed and washing width are decoupled. This allows for the selection of appropriate vehicle speed and washing width according to different road widths and degrees of dirt (the higher the degree of dirt on the road, the lower the corresponding driving speed should be), ensuring the cleaning effect of road washing and improving the efficiency of road washing operations.
[0028] In one embodiment of this utility model, the control unit is voice-controlled, including a voice input module 2 (for acquiring voice commands), a voice processing module (for preprocessing the acquired voice commands to improve signal quality), a voice recognition module (for converting voice into text commands), a semantic understanding module (for parsing the intent and parameters of the text commands), an instruction generation module (for generating control signals based on the intent), and a control execution module (for controlling the equipment to perform corresponding actions based on the control signals). The voice input module 2 is located in the cab of the washing vehicle body 1. The purpose of setting the control unit to voice control is that, compared to the control method of panel buttons, voice control is more convenient for the driver to operate. No hands-free operation is required while driving, thus ensuring driving safety. In practical applications, the control unit is equipped with corresponding voice wake-up words, such as "start flushing operation". After voice wake-up, users can speak voice commands, such as "use low water pressure", "use medium water pressure", and "use high water pressure", or "use level one water pressure", "use level two water pressure", etc. Of course, the road width can also be input by voice (such as "the road width is 14 meters"). The background system will automatically match the corresponding water pressure according to the preset parameters. It should be noted that the voice control technology in this embodiment is existing technology and there are no technical obstacles. Therefore, the connection relationship and principle logic between the above modules will not be elaborated here.
[0029] Please see Figures 2-5 In one embodiment of the present invention, the cab of the washing vehicle body 1 is provided with a mounting bracket 3 for installing the voice input module 2;
[0030] The mounting bracket 3 includes a first base 301 mounted on the top of the cab, a second base 304 slidably mounted on the first base 301, and a second slide block 306 slidably mounted on the second base 304. An adjustable support rod 314 is hinged on the second slide block 306. A bearing member 315 is provided at the movable end of the support rod 314. The voice input module 2 is mounted on the bearing member 315.
[0031] The first base 301 is provided with a first sliding groove 302 running back and forth. A first slide block 303 is slidably engaged in the first sliding groove 302. A second base 304 is provided on the first slide block 303. A pin 310 is provided on the second base 304. The pin 310 slides through the first slide block 303. A plurality of positioning holes 308 adapted to the pin 310 are arranged at the bottom of the first sliding groove 302 for the pin 310 to be inserted to position the first slide block 303 (the radial cross section of the pin 310 is square so that the second base 304 as a whole will not rotate). A boss 311 is provided on the rod segment of the pin 310 located below the first slide block 303. A tension spring 312 is sleeved on the rod segment of the pin 310 located between the first slide block 303 and the boss 311. The two ends of the tension spring 312 are respectively connected to the first slide block 303 and the boss 311.
[0032] The second base 304 is provided with a second sliding groove 305 running vertically, and the second slide block 306 is slidably engaged in the second sliding groove 305. The second sliding groove 305 is also provided with a through groove 313 running vertically on one side. The mounting bracket 3 also includes a first set bolt 307, the screw part of the first set bolt 307 is engaged in the through groove 313 and threadedly connected to the second slide block 306.
[0033] The support rod 314 is hinged to the second slide block 306 via a shaft 316, and a positioning member 317 for fixing the deflection angle of the support rod 314 is threadedly fitted onto the shaft 316.
[0034] It should be noted that the purpose of setting the mounting bracket 3 for mounting the voice input module 2 in this embodiment is as follows: the washing vehicle body 1 is noisy when it is in motion, and loud music is usually played during the washing operation (to serve as a safety warning). In order to avoid noise interference with the voice command acquisition and to ensure stable control of the control unit, the mounting bracket 3 is set so that the voice input module 2 can be moved closer to the driver's mouth (preferably: the voice input module 2 is located in front of the driver's mouth) to ensure accurate and clear acquisition of voice commands. When the washing operation is not required, the mounting bracket 3 can be folded back to avoid interfering with the driver's other operations.
[0035] In this embodiment, in the initial state, the first slide block 303 is located behind the first slide groove 302, which means the second base 304 is located behind the cab (behind the driver's seat), and the support rod 314 and the second base 304 are folded to avoid obstructing or interfering with the driver's other operations. After the driver gets into the vehicle and adjusts the seat position and posture, he pulls down the second base 304 so that the upper end of the pin 310 disengages from the positioning hole 308 in the initial position. Maintaining the current state, the second base 304 is pulled forward to the appropriate position, and the first slide block 303 slides forward along the first slide groove 302 accordingly. Then, the second base 304 is released, and the pin 310 is engaged in the current position under the action of the tension spring 312. The positioning hole 308 is used to position the first slide 303, which in turn positions the second base 304. Then, the support rod 314 is deflected and the second slide 306 moves up and down, which in turn moves the support rod 314 up and down accordingly. The length of the support rod 314 is adjusted (by loosening the positioning piece 317 to deflect the support rod 314, and then tightening the positioning piece 317 to fix the deflection angle of the support rod 314; by loosening the first set bolt 307 to adjust the second slide 306 up and down, and then tightening the first set bolt 307 to position the second slide 306). This moves the voice input module 2 to the position in front of the driver's mouth so that voice commands can be collected accurately and clearly.
[0036] Furthermore, in this embodiment, the first slide groove 302 is provided with a limiting block 309 for restricting the sliding range of the first slide block 303 to prevent the first slide block 303 from slipping off.
[0037] Furthermore, in this embodiment, the support rod 314 includes a first rod body 3141 and a second set bolt 3143 slidably inserted into the first rod body 3141. The first rod body 3141 is also provided with a second rod body 3142 for fixing the length of the support rod 314. The overall length of the support rod 314 is adjusted by pulling the second rod body 3142. After adjusting to an appropriate length, the second set bolt 3143 is tightened.
[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
