Description

Technical Field

[0001] This utility model relates to an intelligent cleaning device for a road sign maintenance vehicle. Background Technology

[0002] Current road sign maintenance typically involves manual washing and wiping. In extreme weather conditions such as extreme cold or heat, workers cannot work outdoors, affecting daily maintenance progress. Furthermore, manual cleaning not only carries the risk of workplace injury but is also less efficient and more costly in the long run compared to machine cleaning. In particular, if the signs are not dried immediately after cleaning, dust can easily accumulate on the surface, resulting in poor cleaning performance. Utility Model Content

[0003] This utility model provides an intelligent cleaning device for a road sign maintenance vehicle.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an intelligent cleaning device for a road sign maintenance vehicle, including a mounting base, a fan mechanism, a spraying mechanism and a support mechanism, wherein the fan mechanism and the spraying mechanism are mounted on the mounting base through the support mechanism;

[0005] The spraying mechanism includes a housing, on which a plurality of water spray heads and a plurality of air outlets are provided. The water spray heads and air outlets are located on the same side of the housing, and the water spray heads are distributed in a matrix. The air outlets are strip-shaped and are arranged horizontally between two rows of water spray heads.

[0006] The box is provided with a gas channel and a liquid channel. On the side of the box away from the water nozzle, there is a water inlet pipe and an air inlet pipe. The water inlet pipe is connected to each water nozzle through the liquid channel, and the air inlet pipe is connected to each air outlet through the gas channel.

[0007] The air-expelling mechanism includes an air-expelling pipe, a heating wire, and a fan blade mechanism. The heating wire and the fan blade mechanism are both installed inside the air-expelling pipe. One end of the air-expelling pipe is connected to the air inlet pipe of the housing. The distance between the heating wire and the air inlet pipe is greater than the distance between the fan blade mechanism and the air inlet pipe. Temperature sensors are installed at both ends of the air-expelling pipe.

[0008] The support mechanism includes a cylinder and a column. The cylinder is vertically mounted on the mounting base, with its bottom hinged to the mounting base and its top rod hinged to the outer wall of the air duct. The lower end of the column is fixed to the mounting base, and its upper end is hinged to the lower end of the housing.

[0009] Preferably, in order to achieve intelligent control and improve the automation level of cleaning, the mounting base is also equipped with a central control box, which contains a PLC and a wireless signal transceiver module.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0018] like Figure 1-2 As shown, an intelligent cleaning device for a road sign maintenance vehicle includes a mounting base 1, an air intake mechanism, a spraying mechanism, and a support mechanism. The air intake mechanism and the spraying mechanism are mounted on the mounting base 1 via the support mechanism.

[0019] The spraying mechanism includes a housing 2, on which a plurality of water spray heads 3 and a plurality of air outlets 4 are provided. The water spray heads 3 and air outlets 4 are arranged on the same side of the housing 1, and the water spray heads 3 are arranged in a matrix. The air outlets 4 are strip-shaped and are arranged horizontally between two rows of water spray heads 3.

[0020] In fact, the water spray heads 3 are distributed all over the side of the entire box 2 in a matrix pattern, while the air outlets 4 are strip-shaped, with an air outlet between each two adjacent rows of water spray heads 3. This arrangement is mainly to improve the responsiveness of the position, that is, after spraying water, the position of the box 2 does not need to be adjusted, and hot air can be sprayed directly from the air outlets 4 onto the surface of the sign for drying.

[0021] The housing 2 is provided with a gas channel and a liquid channel. The side of the housing 2 away from the water nozzle 3 is provided with a water inlet pipe 9 and an air inlet pipe. The water inlet pipe 9 is connected to each water nozzle 3 through the liquid channel, and the air inlet pipe is connected to each air outlet 4 through the gas channel.

[0022] In fact, the water inlet pipe 9 is connected to an external water source. Water enters the liquid channel inside the box 2 from the water inlet pipe 9, and then enters each spray head 3 through the liquid channel to be sprayed out.

[0023] The gas enters the gas channel inside the housing 2 through the air intake pipe 5, and then enters the air outlet 4 from the gas channel before being blown out.

[0024] The air-expelling mechanism includes an air-expelling pipe 5, a heating wire 6, and a fan blade mechanism 7. The heating wire 6 and the fan blade mechanism 7 are both installed inside the air-expelling pipe 5. One end of the air-expelling pipe 5 is connected to the air inlet pipe of the housing 2. The distance between the heating wire 6 and the air inlet pipe is greater than the distance between the fan blade mechanism 7 and the air inlet pipe. Temperature sensors 8 are provided at both ends of the air-expelling pipe 5.

[0025] The heating wire 6 here is actually an electric heating wire, used to heat the air inside the air duct 5.

[0026] In fact, in order to achieve the desired drying effect, the temperature of the hot air blown out from the air outlet 4 needs to reach about 60°C. However, the normal air temperature does not reach this temperature, so the heating wire 6 is needed to heat it.

[0027] The main function of the fan blade mechanism 7 is to draw in external air into the air duct 5 and then blow it out from the air outlet 4. In fact, the fan blade mechanism includes a motor and fan blades, and the motor drives the fan blades to rotate.

[0028] The temperature sensors 8 at both ends of the exhaust duct 5 are mainly used to detect the inlet and outlet air temperatures, thereby enabling intelligent control. Because the inlet and outlet air temperatures are greatly affected by the environment, such as in winter when outdoor temperatures are low and the heated gas cools down quickly, after detecting the gas temperature at the inlet, the PLC controls the system according to the preset temperature range. For example, if the inlet temperature is below 0℃, the PLC controls the heating wire 6 to heat at 80% power. When the temperature sensor 8 at the outlet detects a temperature greater than 70℃, the heating power of the heating wire 6 remains unchanged. This is because the 70℃ hot air still needs to travel a distance before reaching the sign surface, during which time the hot air cools down rapidly. This setting is mainly to ensure that the temperature reaching the sign surface reaches at least 60℃. If the temperature sensor 8 at the outlet detects a temperature below 65℃, the PLC controls the heating wire 6 to heat at full power, indicating extremely cold weather.

[0029] When the intake air temperature is detected to be greater than 40℃, it indicates that the weather is relatively hot and the air cooling rate is slow. The PLC controls the heating wire 6 to operate at a 50% success rate. When the outlet air temperature is detected to be greater than 65℃, the PLC controls the heating wire 6 to maintain the heating power unchanged. When the outlet air temperature is detected to be less than 65℃, the PLC controls the heating wire 6 to increase the heating power until the outlet air temperature can be greater than 65℃.

[0030] The control logic here can be set according to the user's actual needs and the local climate environment, such as the highest and lowest temperatures in extremely cold or hot weather. The initial heating power of the heating wire 6 is set according to the corresponding intake temperature, and the threshold of the outlet temperature is set according to the intake temperature. Because the higher the intake temperature, the hotter the weather, which means the temperature drops more slowly, the threshold of the outlet temperature is set smaller in summer than in winter. This design logic and the corresponding software design are existing technologies and are conventional technical means for those skilled in the art.

[0031] PLC stands for Programmable Logic Controller. It is a type of electronic system that uses a programmable memory to store programs and execute user-oriented instructions such as logic operations, sequential control, timing, counting, and arithmetic operations. PLC is a mathematical operation electronic system specifically designed for industrial applications, and here it is used as a processor.

[0032] Wireless transceiver modules are mainly used for receiving and sending wireless signals, such as Bluetooth.

[0033] The support mechanism includes a cylinder 11 and a column 12. The cylinder 11 is vertically mounted on the mounting base 1. The bottom of the cylinder 11 is hinged to the mounting base 1. The top of the cylinder rod is hinged to the outer wall of the air duct 5. The lower end of the column 12 is fixed to the mounting base 1, and the upper end of the column 12 is hinged to the lower end of the housing 2.

[0034] This design not only supports the housing 2 and the air intake mechanism, but also allows for angle adjustment of the spray nozzle 3 and air outlet 4 through the extension and retraction of the cylinder 11, and also enables cyclic swinging to increase the cleaning range.

[0035] Preferably, in order to achieve intelligent control and improve the automation level of cleaning, the mounting base 1 is also provided with a central control box 13. The central control box 13 is equipped with a PLC and a wireless signal transceiver module. The water inlet pipe is equipped with an electromagnetic water valve 10. The temperature sensor 8, electromagnetic water valve 10, cylinder 11, heating wire 6, fan blade mechanism 7 and wireless signal transceiver module are all electrically connected to the PLC.

[0036] In fact, the PLC controls the motor of the fan blade mechanism.

[0037] This system is controlled by a PLC. When spraying water, the solenoid water valve 10 is opened and the fan mechanism 7 is not working. After spraying water, the PLC controls the solenoid water valve 10 to close and then controls the fan mechanism 7 to work. The fan mechanism draws in air, and based on the temperature feedback detected by the two temperature sensors 8, the PLC controls the heating wire 6 to work. This system can be wirelessly connected to the backend via a wireless signal transceiver module to achieve remote control of the device.

[0038] Preferably, in order to prevent leaves from entering the air intake pipe 5, a filter screen is provided at the end of the air intake pipe 5 away from the air inlet pipe.

[0039] Preferably, to improve the cleaning effect, the spray head 3 is a pressurized nozzle.

[0040] Compared with existing technologies, the intelligent cleaning device of this road sign maintenance vehicle achieves comprehensive cleaning of the signs by setting up a matrix spray head 3, and then heats the introduced air through the air intake mechanism to dry the surface of the signs, reducing the accumulation of dust on the damp surface and improving the cleaning effect. Furthermore, the angle of the spray mechanism can be adjusted through the support mechanism to increase the cleaning range, and two temperature sensors 8 are set up to detect the temperature of the gas in real time, saving energy while ensuring the drying effect.

[0041] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
