Description

Technical Field

[0001] The invention relates to the technical field of dust reduction during road construction, and in particular to a linear dust reduction device and method for highway road construction. Background Art

[0002] With the continuous acceleration of urbanization, the number of transportation infrastructure construction projects has gradually increased, such as highways, high-speed railways, urban rail transit, etc. However, a large amount of dust pollution will be generated during the construction of these projects, which will have a negative impact on the surrounding environment and human health. Therefore, how to reduce the dust pollution generated during the construction of roadbed projects has become an urgent problem to be solved.

[0003] When in use, the existing environmentally friendly dust reduction devices for road construction mostly use a spray device to spray dust reduction water mist into the atmosphere, and generally a plurality of dust detectors are arranged on the outside of the device, so that the dust detectors can be used to detect the dust in the air after the dust reduction to determine whether the location needs to continue the dust reduction.

[0004] However, in the process of using the existing method, a dust detector is only set to detect whether the dust is completely removed at the spraying position. When the outside weather is at high temperature, the water mist sprayed by the dust reduction device will evaporate quickly in the air, and the water mist cannot be sprayed within the specified range. The water mist will evaporate before reaching the farthest dust reduction area, making it impossible for the water mist to completely remove dust within the specified range.

[0005] In order to achieve comprehensive dust reduction, high-power dust reduction spray devices are often used to perform "exceeding the standard" dust reduction. Although dust reduction can be achieved in the entire area under any circumstances, it also causes a waste of water and electricity (for example, when the temperature is not high or the air is relatively humid, the water mist evaporates less and more slowly during the dust reduction spray process, and dust can be reduced in distant areas without the need for a large spray volume or water supply power).

[0006] In summary, how to effectively resolve the contradiction between the high energy consumption (high water volume, high electricity) required for comprehensive dust suppression generated during construction operations and the high energy consumption (high water volume, high electricity) required for water spraying to suppress dust has become a problem that needs to be solved.

The system adjusts the water output of the water pump in real time, so that the device can comprehensively reduce dust in the specified range area during operation, and adjusts the water output during the dust reduction process to achieve the purpose of dust reduction with less water.

The photoelectric signal transmitting module and the photoelectric signal receiving module are powered on and maintained, the photoelectric signal strength emitted by the photoelectric signal transmitting module is φ1, and the photoelectric signal strength received by the photoelectric signal receiving module is φ2. This is the initial detection of the dust concentration detection area when there is no operation.

[0021] S3. Construction work starts, dust appears, the water spray assembly starts, the water pump transports the water in the water storage tank to the water pipe, and then sprays it out from the nozzle to spray water mist on the dusty area of ​​the construction work.

[0022] S4. At the same time, the temperature sensor and humidity sensor start working. The temperature sensor detects that the external environment temperature is W x , the humidity sensor detects the external environment humidity U x , the system presets the standard temperature reference value W 标准 And the standard humidity reference value U 标准 .

[0024] Then the temperature difference △W=|W x -W 标准 |, humidity difference △U=|U x -U 标准 |.

[0025] S4. The system controls the real-time water output power of the water spraying component P = P min +△P1+△P2, until the photoelectric signal strength φ received by the photoelectric signal receiving module in real time x Not less than φ2.

[0026] Among them, P minis the minimum water output power, △P1 is the temperature and humidity change power, △P2 is the maximum dust reduction driving power, temperature and humidity change power: to adjust the water output, the water output power needs to be controlled according to the changes in temperature and humidity. Maximum dust reduction driving power: to reduce the amount of dust exceeding the standard at the farthest distance from the target, the water output power part that needs to be controlled. The greater the amount of dust exceeding the standard at the farthest distance from the target, the greater the △P2. The smaller the amount of dust exceeding the standard at the farthest distance from the target, the smaller the △P2.

[0027] S4.1.W x >W 标准 , U x <U 标准 ; Then F(△P1)∝[F(△W)·F(△U)]. When the outside temperature is higher than the reference value and the humidity is lower than the reference value, the temperature difference and humidity difference are both negative factors. The greater the temperature difference and humidity difference, the greater the temperature and humidity change power △P1.

[0028] S4.2.W x >W 标准 , U x >U 标准 ; Then F(△P1)∝[F(△W) / F(△U)]. When the outside temperature is higher than the reference value and the humidity is higher than the reference value, the temperature difference is a negative factor and the humidity difference is a positive factor. The greater the temperature difference and the smaller the humidity difference, the greater the temperature and humidity change power △P1.

[0029] S4.3.W x <W 标准 , U x <U 标准 ; Then F(△P1)∝[F(△U) / F(△W)]. When the outside temperature is lower than the reference value and the humidity is lower than the reference value, the temperature difference is a positive factor and the humidity difference is a negative factor. The smaller the temperature difference and the greater the humidity difference, the greater the temperature and humidity change power △P1.

[0030] S4.4.W x =W 标准 , U x >U 标准 ; Then F(△P1)∝[1 / F(△U)]. When the outside temperature is the same as the reference value, the influence of temperature difference is not considered. When the humidity is higher than the reference value, the humidity difference is a positive factor. The greater the humidity difference, the smaller the temperature and humidity change power △P1.

[0031] S4.5.W x =W 标准 , U x <U 标准; Then F(△P1)∝F(△U). When the outside temperature is the same as the reference value, the influence of temperature difference is not considered. When the humidity is lower than the reference value, the humidity difference is a negative factor. The greater the humidity difference, the greater the temperature and humidity change power △P1.

[0032] S4.6.W x >W 标准 , U x =U 标准 ; Then F(△P1)∝F(△W). When the outside humidity is the same as the reference value, the influence of humidity difference is not considered. When the temperature is higher than the reference value, the temperature difference is a negative factor. The greater the temperature difference, the greater the temperature and humidity change power △P1.

[0033] S4.7.W x <W 标准 , U x =U 标准 ; Then F(△P1)∝[1 / F(△W)]. When the outside humidity is the same as the reference value, the influence of humidity difference is not considered. When the temperature is lower than the reference value, the temperature difference is a positive factor. The greater the temperature difference, the smaller the temperature and humidity change power △P1.

[0034] Among them, F(△P1) is the function parameter value of the temperature and humidity change power △P1, F(△W) is the function parameter value of the temperature difference △W, and F(△U) is the function parameter value of the humidity difference △U.

[0035] S4.8.F(△P2)∝F(△φ), photoelectric signal strength difference △φ=|φ x -φ2|.

[0036] Among them, F(△P2) is the function parameter value of the maximum dust reduction driving power △P2, and F(△φ) is the function parameter value of the photoelectric signal intensity difference △φ.

[0037] The present invention provides a linear dust reduction device for highway construction, which has the following beneficial effects:

[0038] (1) The present invention cooperates with a temperature sensor, a photoelectric signal transmitting module, a photoelectric signal receiving module and a humidity sensor. When the temperature sensor detects that the outside temperature is high and the humidity sensor detects that the humidity in the outside air is low, the control system will adjust the water pressure of the water pump, thereby increasing the water output of the water pump, so that water mist can be sprayed on the dust concentration detection area, thereby avoiding the problem that the water mist cannot be sprayed on the dust concentration detection area due to the high temperature and the rapid evaporation of water vapor. After the water mist is sprayed on the dust concentration detection area, the control system can adjust the water pressure of the water pump to gradually reduce the water output of the water pump. When the dust concentration in the dust concentration detection area exceeds the standard again and it is necessary to increase the water pressure again, the water output power of the water pump is increased again until the dust concentration in the dust concentration detection area meets the standard, so that the water pump can achieve the purpose of dust reduction with less water output, effectively resolving the contradiction between the high energy consumption required for comprehensive dust reduction of dust generated during construction work and the high energy consumption required for water spraying to reduce dust.

[0043] Embodiment 1: The present invention designs a linear dust reduction device for highway road construction, which mainly includes the following contents:

[0044] Combination Figure 1 , Figure 2 The water spraying assembly includes a mobile cart, which includes a base plate 1, mobile wheels 2 arranged at four corners of the lower side of the base plate 1, and a cart handle 9 fixedly connected to the base plate 1. The water storage barrel 3 is fixedly installed on the upper side of the base plate 1, the water storage barrel 3 is fixedly installed on the upper side of the mobile cart, a water pump 4 connected to the water storage barrel 3, and a nozzle 5 installed on the water outlet side of the water pump 4, wherein a placement plate 6 is fixedly installed on the ring side of the water storage barrel 3, the water pump 4 is fixedly installed on the placement plate 6, and a feeding port for feeding dust suppression water is provided on the top of the water storage barrel 3.

[0045] The external environment detection component includes a temperature sensor 7 and a humidity sensor 8 fixedly mounted on the mobile cart, wherein the detection direction of the temperature sensor 7 and the humidity sensor 8 is opposite to the spraying direction of the nozzle 5 .

[0046] The dust concentration detection component includes a photoelectric signal transmitting module 11 and a photoelectric signal receiving module 12 fixedly installed in a designated area. The photoelectric signal transmitting module 11 and the photoelectric signal receiving module 12 are independently installed on a column 10. Assuming that the distance between the nozzle 5 and the dust concentration detection area 13 is La, the rated distance of the water pump 4 driving the nozzle 5 to spray is not less than La. The photoelectric signal transmitting module 11 and the photoelectric signal receiving module 12 are independently configured with a power supply module and a wireless transmission module. A dust concentration detection area 13 is formed between the photoelectric signal transmitting module 11 and the photoelectric signal receiving module 12, and the dust concentration detection area 13 is located at the boundary of the dust area caused by the construction work.

[0047] The controller is configured with a temperature monitoring module for analyzing temperature information, a humidity monitoring module for analyzing humidity information, a water output power adjustment module for regulating the power of the water pump 4, and a wireless transmission module for receiving wireless signals from the photoelectric signal transmitting module 11 and the photoelectric signal receiving module 12.

[0048] The dust suppression device also includes a power module, which is a rechargeable battery or a directly connected external 220V power supply.

[0049] Embodiment 2: In the present invention, a method for using a linear dust suppression device for highway construction, the specific working principle is as follows:

[0050] First, the pushing device is moved to the position where dust reduction is required, and the column 10 is inserted into the edge of the spraying range. The water mist spraying dust reduction situation in the dust concentration detection area 13 is judged by the intensity of the photoelectric signal transmitted between the photoelectric signal transmitting module 11 and the photoelectric signal receiving module 12. If the photoelectric signal received by the photoelectric signal receiving module 12 is strong, it means that the dust content in the air is low, and the water mist is sprayed into the dust concentration detection area 13.

[0051] If the photoelectric signal received by the photoelectric signal receiving module 12 is weak, it means that the dust content in the air is high, the water mist is not sprayed to the dust concentration detection area 13 or the amount of water sprayed to the dust concentration detection area 13 is insufficient.

[0052] The temperature sensor 7 and the humidity sensor 8 work together. The temperature sensor 7 detects the external temperature and the humidity sensor 8 detects the external humidity. When the temperature sensor 7 detects that the external temperature is greater than W 标准 , the humidity detected by the humidity sensor 8 is less than U 标准The control system will adjust the water output power of the water pump 4 and increase the water pressure of the water pump 4, thereby increasing the water output of the water pump 4 and the water output pressure of the nozzle 5, so that the water mist can be sprayed to the dust concentration detection area 13.

[0053] When the photoelectric signal received by the photoelectric signal receiving module 12 strengthens, the system will control the water pump 4 to gradually reduce the water output until the photoelectric signal received by the photoelectric signal receiving module 12 weakens, and the dust concentration in the dust concentration detection area 13 exceeds the standard again. When the water pressure needs to be increased again, the water output power of the water pump 4 is increased until the dust concentration in the dust concentration detection area 13 meets the standard.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
