Description

Technical Field

[0001] The invention relates to the technical field of urban road maintenance and management, and in particular to a road water spraying cooling and dust reduction system. Background Art

[0002] With the rapid advancement of global climate change and urbanization, urban roads are facing increasingly severe heat island effects and air pollution problems. Especially in summer, high temperatures lead to higher road surface temperatures, which not only accelerates the aging of pavement materials, but also exacerbates the urban heat island effect, affecting the quality of life and health of urban residents. At the same time, dust pollution generated by activities such as vehicle driving and construction further deteriorates urban air quality and increases the risk of respiratory diseases.

[0003] The traditional way of cooling and dust reduction on roads mainly relies on manual spraying by sprinkler trucks, which has many shortcomings. First, the operation of sprinkler trucks consumes a large amount of tap water resources. In the current context of increasingly tight water resources, the sustainability of this method is questioned. Secondly, the amount of water and water pressure sprayed by sprinkler trucks are limited, and the cooling and dust reduction effects are not significant enough, especially in hot and dry weather conditions. In addition, the operation of sprinkler trucks is also limited by factors such as time, manpower and transportation, making it difficult to achieve all-weather and all-round coverage.

[0004] In order to solve the above problems, domestic and foreign scholars and engineers have begun to explore new methods of using rainwater resources to cool and reduce dust on roads in recent years. As a natural water resource, rainwater is inexhaustible and has relatively good water quality. It can be used for road spraying after simple treatment. However, how to efficiently and safely collect and use rainwater resources, and how to realize automated spraying operations, have become key factors restricting the development of this technology.

[0005] In this context, the present invention proposes a road water spraying cooling and dust reduction system to solve the above-mentioned technical problems. Summary of the invention

[0010] Furthermore, V-shaped slope surfaces are respectively provided at the connection points between the two sides of the transition zone and the carriageway area and the pedestrian area.

[0020] The road water spraying cooling and dust reduction system of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0021] In conjunction with the accompanying drawings, a road water spray cooling and dust reduction system includes a road 1, a rainwater collection well 2, a clean water pool 7, a water storage pool 9, a pier-type high-pressure water pump 10 and an umbrella-shaped nozzle 12. The road 1 includes a carriageway area 101, a pedestrian area 102 and a transition area 103. The pedestrian areas 102 are respectively arranged on both sides of the carriageway area 101. Transition areas 103 are respectively arranged between the carriageway area 101 and the pedestrian areas 102 on both sides.

[0022] Each of the transition zones 103 is provided with a rainwater collection well 2, a support frame 5 is provided on the well wall of the rainwater collection well 2, a filter screen 4 is provided on the support frame 5, a well cover 3 is provided at the well mouth of the rainwater collection well 2, the rainwater collection well 2 is arranged adjacent to the clean water pool 7, and the two are separated by an overflow wall 6;

[0023] A water reservoir 9 is provided at the bottom of the carriageway area 101, and the clean water tank 7 is connected to the water reservoir 9 through an inlet pipe 8. A pier-type high-pressure water pump 10 is installed in the water reservoir 9, and the water outlet end of the pier-type high-pressure water pump 10 is connected to a water outlet pipe 11, and a plurality of umbrella-shaped nozzles 12 are installed on the water outlet pipe 11. A water temperature sensor 14 and an electric heater 13 are installed in the water reservoir 9.

[0024] As a preferred implementation scheme of this embodiment, V-shaped slope surfaces are respectively provided at the connection points between the two sides of the transition zone 103 and the carriageway zone 101 and the pedestrian zone 102.

[0025] As a preferred implementation scheme of this embodiment, the V-shaped slope surfaces are inclined toward the transition area 103, and the slope of the V-shaped slope surfaces is 3-5 degrees.

[0026] As a preferred implementation scheme of this embodiment, the well wall of the rainwater collection well 2 is fixedly connected to the supporting frame 5.

[0027] As a preferred implementation scheme of this embodiment, the bottom surface of the filter screen 4 is in contact with the upper surface of the support frame 5.

[0028] As a preferred implementation scheme of this embodiment, the water outlet end of the pier-type high-pressure water pump 10 is connected to a three-way pipe fitting, and the three-way pipe fitting is connected to the water outlet pipe 11. The water outlet pipe 11 is provided with a plurality of water outlet branches, and each of the water outlet branches is respectively installed with an umbrella-shaped nozzle 12.

[0029] As a preferred implementation scheme of this embodiment, the water temperature sensor 14 can transmit the monitoring data to the control room through wired or wireless communication. The control room is electrically connected to the electric heater 13 and the pier-type high-pressure water pump 10 respectively, and is used to control the start and stop of the electric heater 13 and the pier-type high-pressure water pump 10.

[0030] During the specific implementation of the present invention, when rainfall occurs, rainwater first falls on the road, especially on the carriageway area 101 and the pedestrian area 102. Due to the design of the transition area 103, rainwater will naturally flow to and collect in the rainwater collection well 2 in the transition area 103. Rainwater enters through the wellhead of the rainwater collection well 2, and first passes through the filter screen 4 to remove larger impurities and particulate matter to prevent them from entering the clean water tank 7. The filtered rainwater will flow into the clean water tank 7. The rainwater will naturally precipitate small particles in the rainwater collection well 2. Because the clean water tank 7 and the rainwater collection well 2 are separated by an overflow wall 6, it is ensured that only rainwater that has been filtered and naturally precipitated can enter the clean water tank 7. The purified rainwater is transported to the reservoir 9 through the water inlet pipe 8 for storage for subsequent use.

[0031] When water spraying is needed to cool down and reduce dust, the control room will start the pier-type high-pressure water pump 10. The pier-type high-pressure water pump 10 draws water from the water reservoir 9 and sends the water to multiple water outlet branches through the three-way pipe connected to the water outlet end. Each water outlet branch is equipped with an umbrella-shaped nozzle 12, which will spray fine water mist at high pressure to cover the road surface, achieving the effect of cooling and reducing dust.

[0032] The water temperature sensor 14 installed in the water reservoir 9 monitors the water temperature in real time. If the water temperature is too low (especially in cold seasons), it may affect the spraying effect and even cause the nozzle to freeze. When the water temperature sensor 14 detects that the water temperature is lower than the set value, the control room will start the electric heater 13 to heat the water in the water reservoir 9 to ensure that the water temperature remains within an appropriate range.

[0033] During routine maintenance, the filter screen 4 of the rainwater collection well 2 needs to be checked regularly to clean the blocked impurities to ensure that rainwater can flow in and be filtered smoothly. At the same time, the water temperature sensor 14, the electric heater 13 and the pier-type high-pressure water pump 10 are remotely monitored and controlled through the control room to ensure stable operation of the system.

[0034] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
