Abstract

The present invention relates to a hydrogen electricity road dust suction cleaning vehicle and, more particularly, to a new concept technique, which can drive a blower by using electricity produced by chemically reacting hydrogen and oxygen to exhibit far higher suction performance and reduce the cross-sectional area of the suction port of a variable suction unit if the concentration of fine dust accumulated on the road surface is high, thereby easily cleaning hardened dust and fine dust that cannot be cleaned. The conventionally disclosed road dust suction cleaning vehicle caused a problem that it was practically difficult to maintain a proper rotational speed of a blower according to the concentration of fine dust in the air and the degree of contamination of a filter. To solve the problem, devised is a technique for detecting the concentration of fine dust while forcibly suctioning re-scattering dust by using a re-scattering dust suction pipe, receiving speed information from a GPS to a vehicle control unit (VCU), performing signal processing thereon to finally change the rotational speed of the blower into an optimal state through a motor driver, and enabling the motor driver to control the rotational speed of the blower in an optimal state while driving the blower motor by using electricity produced by fuel cells. Therefore, the hydrogen electricity road dust suction cleaning vehicle can exert optimal suction power, thereby efficiently cleaning the fine dust scattered on the road surface.

Description

Hydrogen electricity road dust suction cleaning vehicle with automatic control device for suction power according to fine dust concentration and vehicle speed

The present invention is a method of driving a blower using electricity produced by chemical reaction of hydrogen and oxygen. By measuring the concentration of fine dust accumulated on the road surface, when the concentration is high, the suction performance is significantly higher than that of a conventional vacuum cleaner. It relates to a new concept of technology that narrows the cross-sectional area of the suction port of the display and variable type suction unit to easily clean the fixed dust and fine dust that cannot be cleaned.

In general, each local government or an institution that manages roads carries out work to keep the road surface clean by removing foreign substances accumulated on the road surface in a timely manner for roads that have already been built and used.

The road cleaning work as described above has a large cleaning area, so if the work is done by manpower, the efficiency is very low, and the risk of accidents is high because the work is performed in a situation where vehicles are driving around, so a structure suitable for road cleaning is required. The cleaning work is performed using the road surface cleaning vehicle manufactured to have it.

Most of the above-mentioned road surface cleaning vehicles are equipped with a water spray nozzle that sprays water, a brush and a vacuum suction device for collecting various kinds of garbage on the road, so that water is sprayed from the front of the vehicle, and then the garbage is removed using a brush and a vacuum suction machine. Since this series of work is performed in the process of driving the vehicle, there is an advantage in that road cleaning can be performed safely while minimizing traffic congestion.

However, in winter, the water sprayed on the road freezes on the road to form an icy section, so it is practically impossible to use due to a problem that increases the risk of traffic accidents. There was a problem in that a large amount of budget was required for road cleaning work because a large amount of water was required for cleaning, as well as causing secondary pollution.

Therefore, recently, road dust suction cleaners have been introduced that use a vacuum suction mouse to clean dust and fine dust scattered in gaps (voids) of roads by vacuum suction method without spraying water like the road surface cleaning vehicle.

When cleaning road dust using such a road dust suction cleaner, the driver sets the blower rotation speed initially and proceeds without changing the rotation speed due to many vehicles traveling on the road, vehicles parked on the roadside, and other obstacles. Most of the time, the driver has to pay attention to both driving and cleaning the vehicle at the same time, causing a very inconvenient problem.

As the prior art related to the road dust suction cleaning vehicle, "Patent Registration No. 1827474, title/road dust suction vehicle to which an air jetting system with improved suction power and a filter control system for suppressing fine dust emission is applied", which is a pre-registered inventor of the present applicant, is proposed. is becoming

The prior art compares the pressure difference between the front end (high pressure side) and the rear end (low pressure side) of the filter measured by a differential pressure gauge with a set pressure through a controller to quantify the level of pollution of the filter and visually confirm the level of pollution of the filter The filter can be automatically cleaned or replaced after the operator visually confirms it when it is time to replace it.

All road dust suction cleaning vehicles including the prior art are used to clean, but when a lot of dust and fine dust accumulates on the road and becomes stuck in crevices, it is impossible or difficult to clean with existing cleaning vehicles, especially the power of the internal combustion engine. Due to the mechanical control method of driving the blower using a mechanical control method, environmental pollution occurs and noise and vibration are generated, which makes the durability of the vehicle vulnerable and causes a lot of noise.

However, since there are many parts that drivers need to pay attention to other than cleaning work, such as driving vehicles and vehicles parked on the roadside, it is practically difficult to maintain an appropriate blower rotation speed according to the concentration of fine dust in the air and the pollution level of the filter. In many circumstances, if the blower speed is maintained at a high speed even in a situation where the concentration of fine dust in the air and the pollution degree of the filter are good, the load is unnecessarily increased, reducing the life of the driving device as well as increasing the fuel consumption and the emission of exhaust gas. this is caused

In addition, when a lot of dust and fine dust are accumulated on the road and become stuck in crevices, etc., it is impossible or difficult to clean with an existing cleaning vehicle.

The present invention is a means for solving the above problems, considering that fine dust accumulated on the road surface is re-scattered into the atmosphere due to friction between the tires of the work vehicle and the road surface, re-scattering dust is forced using a re-scattering dust suction pipe. While inhaling, it detects the concentration of fine dust, and at the same time receives speed information from the GPS to the vehicle control unit (VCU), processes the signal, and finally changes the rotation speed of the blower to the optimal state through the motor driver. The motor driver drives the blower using electricity generated from the fuel cell, and when the concentration is high, the suction performance is significantly higher than the suction performance of the existing cleaning car, and the suction port of the variable suction unit is narrowed to remove the fixed dust and fine dust that cannot be cleaned. Learn techniques for easy cleaning.

In addition, as a specific solution for this, when the speed of the vehicle is low and the concentration of fine dust is low, the operation is performed by controlling the rotation speed of the blower low. In addition to increasing the rotation speed of the variable suction unit, the cross-sectional area of the inlet of the variable suction unit is narrowed to maintain the best suction power and to inhale fine dust from the road surface without leakage.

In addition, the present invention purifies the atmosphere using a slight blower suction power to the driving wind by setting the rotational speed of the blower to a low level while the air purification device that sucks fine dust in the air during general driving or work is running, and works On the way, we seek a technology to purify the air by setting the rotation speed of the blower high.

According to the present invention, by measuring the concentration of fine dust accumulated on the road surface and vehicle speed through GPS during automatic mode operation, the speed of the blower and the inlet cross-sectional area of the variable suction unit are automatically optimized and adjusted so that the driver can focus on driving. The fatigue level is reduced, the risk of safety accidents is reduced, and the optimal suction power provides the effect of efficiently cleaning fine dust scattered on the road surface.

In addition, the present invention does not use an internal combustion engine and uses a fuel cell that produces electricity by chemical reaction of hydrogen and oxygen, so that exhaust gases other than water are not generated, thereby fundamentally preventing environmental damage caused by various harmful substances and greenhouse gases. It provides a blocking effect.

In addition, according to the present invention, automatic control is performed by the controller so that power optimized for the driving speed of the vehicle and the concentration of fine dust on the road surface can be achieved, thereby reducing the overload of the engine to increase the durability of the engine, saving fuel and exhaust gas It provides the effect of reducing environmental pollution by reducing emissions.

Furthermore, the present invention uses the air purification device connected to the blower to remove fine dust from the road surface by inhaling fine dust in the air during general driving or work using the air purification device, as well as incidentally improving air quality. This provides the effect of maximizing the utilization of the road dust suction cleaning vehicle.

In the road dust suction cleaning car (7) that is loaded in the car loading box (3) and discharged into the atmosphere through the dust collecting filter (6) in the secondary loading box (5) via the blower (4),

First, according to the present invention, the fine dust concentration detected using the fine dust sensor 20 and the speed information of the GPS 100 are input to the vehicle control device 110 and processed as an operation signal by the transceiver 120 By transmitting an operation signal to the motor driver 130 through wireless communication, and driving the blower motor 140 through the motor driver 130, the number of rotations of the blower 4 is finally varied.

In addition, according to the present invention, as shown in FIG. 1A , hydrogen and oxygen are chemically reacted in the fuel cell 150 to generate electricity and stored in the energy storage device 160 , and the energy storage device 160 operates the motor driver ( By supplying electricity stored in 130 , the motor driver 130 can variably control the rotation speed of the blower 4 while driving the blower motor 140 using electricity.

Meanwhile, in the present invention, the means for detecting fine dust includes a sensor box 10 attached to the front of the primary loading box 3 , a fine dust detection sensor 20 , and a pair of re-scattering dust suction pipes 30 . It can be seen that they are divided into the components of

Hereinafter, the present invention having the above schematic configuration will be described in more detail to facilitate implementation.

First, the sensor housing 10 for accommodating the fine dust detection sensor 20 is integrally attached to the front surface of the primary loading box 3, and an airtight gasket 12a is installed in the inspection hole 11 formed open on the front side. In the butt state, the inspection cover 12 penetrates through the fixing bolt 12b and is installed to be detachable.

And a fine dust detection chamber 13 for detecting the concentration of fine dust re-scattering from the road surface is formed on one side of the bottom surface of the sensor housing 10, and a pair of fine particles is formed on the front side of the fine dust detection chamber 13 The dust through-holes 14 are formed at a distance from each other, and the fine dust through-holes 14a communicating with the fine dust inlet holes 3a penetrating through the front of the primary loading box 3 are formed on the rear side.

The fine dust detection sensor 20 penetrates through a pair of fixing bolts 21 , and a reinforcing plate 22 is integrally attached to the rear surface, and the reinforcing plate 22 is in close contact with the inner surface of the sensor housing 10 . A pair of fixing bolts 21 are inserted into a pair of long holes 15 formed in the sensor housing 10 , and the fine dust detecting unit 23 protruding from the lower end of the fine dust detecting sensor 20 is a sensor It is installed exposed to the inside of the fine dust detection chamber 13 through the bottom surface of the housing (10).

Here, the fine dust detection unit 23 is installed through the airtight holder 16 attached to the bottom surface of the sensor housing 10 so that the re-scattered dust collected into the fine dust detection chamber 13 is removed from the sensor housing. The sensor adhesion bolt 24 that is screwed through the bolt fixing bracket 17 attached to the front surface of the upper sensor housing 10 of the fine dust detection sensor 20 and is screwed into the By pressing the fine dust sensor 20 downwards using a clamping force, it maintains a more reliable airtightness to maintain a stable fixed state, and effectively prevents re-scattering dust from entering the inside of the sensor housing 10 .

The upper side of each pair of re-scattering dust suction pipes 30 is integrally connected to the pair of fine dust through holes 14 formed in the front surface of the fine dust detection chamber 13 to allow ventilation, and the lower side is a road dust suction cleaning vehicle (7) is integrally connected with the re-scattering dust suction head 31 located at the rear of the front tire 8 on both sides, and the re-scattering dust suction head 31 has a wide entrance to facilitate the inflow of the re-scattering dust and the rear It is formed in a shape that the cross-sectional area becomes smaller as it increases.

Therefore, when the road dust suction cleaning vehicle 7 is driven, fine dust re-scattered into the atmosphere due to friction between the tire 8 and the road surface is sucked into the re-scattering dust suction head 31, and a pair of re-scattering dust suction pipes 30 ) to the inside of the fine dust detection chamber 13, and then to the primary loading box 3, and measure the fine dust concentration of the re-scattered dust collected inside the fine dust detection chamber 13 in this way. Therefore, it is possible to more effectively remove fine dust by automatically controlling the rotation speed of the blower 4 based on this.

Here, the re-scattering dust suction head 31 is additionally grafted with a technology that allows the re-scattering dust to be collected more efficiently by freely adjusting the inclination according to the on-site situation and the specifications of the vehicle V.

As a technical configuration for this, the re-scattering dust suction head 31 has a connecting bracket 32 integrally protruding from the center of the upper end as shown in FIGS. 8 to 9, and the front and rear upper ends of the connecting bracket 32 are respectively A pair of rotating bosses 33 and 33a penetrate and are integrally attached, and the pair of rotating bosses 33 and 33a are attached to both sides of the vehicle (V) main frame (V-1) "∩" It is inserted into the "shaped suction head fixing bracket 34.

And the rear rotary boss (33a) among the pair of rotary bosses (33) (33a) penetrates through the lower rear both sides of the suction head fixing bracket (34) and the hinge bolt (35) to be rotatably coupled up and down, the front The rotary boss 33 of the suction head fixing bracket 34 is coupled through the angle adjustment slot 36 and the angle adjustment bolt 37 formed along the circumferential direction on both sides of the front lower end.

Accordingly, in a state in which the angle adjustment bolt 37 is loosened, the angle of the re-scattering dust suction head 31 is appropriately adjusted up and down, and then the angle adjustment bolt 37 is tightened to maintain a fixed state.

In the present invention having such a configuration, the fine dust detection sensor 20 detects the fine dust concentration of the re-scattering dust collected by forcibly sucking it into the fine dust detection chamber 13 by the re-scattering dust suction pipe 30, and at the same time By measuring the speed of the vehicle (V) through the GPS (100) installed in the driver's seat and automatically controlling the rotation speed of the blower (4) through the controller based on the transmitted data, the driver can focus on driving, thereby reducing the driver's fatigue Reduces the risk of safety accidents by reducing

That is, when the speed of the vehicle V is low and the concentration of fine dust is low, the operation is performed by controlling the rotation speed of the blower 4 low, and the concentration of fine dust is measured high or the speed of the vehicle V is high. It is possible to perform the work by controlling the rotation speed of the ground blower (4) high.

On the other hand, at the upper end of the exhaust duct 4a connected between the blower 4 and the secondary loading box 5, an air jet injection pipe 40 is branched as shown in FIG. 6, and the air jet injection pipe 40 is installed to penetrate the fine dust detection chamber 13 and face the fine dust detection unit 23 inside, and at the rear of the lower end of the airjet injection pipe 40, on the inner upper surface of the exhaust duct 4a. Since the air jet guide blade 41 is integrally attached, the air jet can be more smoothly guided and supplied to the air jet injection pipe 40 .

Therefore, the exhaust that has passed through the exhaust duct 4a is introduced into the air jet injection pipe 40, and the washing nozzle 42 coupled to the upper end of the air jet injection pipe 40 detects the air jet by the fine dust detection unit 23 ) by spraying it to cleanly clean the fine dust that has adhered to it, thereby providing the effect of preventing errors in the detection of fine dust.

In addition, the present invention automatically narrows or widens the cross-sectional area of the inlet (50a) of the variable suction unit (50) while maintaining the best suction power and the variable suction unit (50) for optimally sucking fine dust from the road surface without leakage. of technology is further applied.

For this, the variable suction unit 50 has a fixed rubber plate 52 installed on the rubber plate fixing bracket 51 attached to the lower rear side of the suction mouse 1 as shown in FIG. 10, and a rotation support bracket attached to the lower front side ( 53), a rubber plate rotation bracket 54 in the shape of “a” is rotatably coupled through a hinge pin 55 , and a variable rubber plate 56 is installed in the rubber plate rotation bracket 54 , and the rubber plate rotation bracket A variable control spring 58 is integrally connected between the front end of 54 and the spring tension adjustment bolt 57 installed through the bolt fixing bracket 57a attached to the front of the suction mouse 1 .

Therefore, the variable rubber plate 56 is pulled backward due to an increase in suction power when the rotation speed of the blower 4 increases while maintaining elasticity, thereby narrowing the cross-sectional area of the suction port 50a to automatically increase the suction power. In addition, when the number of revolutions of the blower 4 is lowered, the variable rubber plate 56 is pulled forward by the tensile force of the variable control spring 58 while the suction force is lowered and the cross-sectional area of the suction port 50a is enlarged to automatically lower the suction force. By automatically adjusting the cross-sectional area of the intake port (50a) of the suction unit (50), proper suction power can be maintained, thereby reducing engine overload to increase engine durability, saving fuel and reducing exhaust gas emissions, thereby reducing environmental pollution. provides an effect.

In addition, the present invention is additionally grafted with the technology of the air purification device 60 to allow the inhalation of fine dust in the air during general driving or work.

For this purpose, the air purification device 60 has a plurality of atmospheric fine dust suction holes 61 penetrating through the upper front of the dust suction tower 2 as shown in FIGS. 11 to 12 , and the suction duct of the blower 4 ( 4b) and an atmospheric fine dust suction pipe 62 are connected and installed to allow ventilation, and between the atmospheric fine dust suction pipe 62 and the inner surface of the dust suction tower 2 in which the atmospheric fine dust suction hole 61 is formed. The guide pipe 63 is integrally connected.

Here, the atmospheric fine dust guide pipe 63 has a funnel shape in which the cross-sectional area is narrowed toward the rear to increase the flow rate to further smoothly inhale the atmospheric fine dust.

Such an air purification device 60 sets the rotation speed of the blower 4 low during general driving to purify the atmosphere using only a slight blower 4 suction power in the running wind, and the rotation speed of the blower 4 during operation. It provides a special effect of maximizing the utility of the road dust suction vacuum cleaner 7 by not only removing fine dust from the road surface, but also improving air quality incidentally by setting it high to purify the air smoothly.
