Description

Technical Field

[0002] A power plant is a power plant that converts some form of raw energy into electrical energy for fixed facilities or transportation, such as thermal, hydro, steam, diesel or nuclear power plants. During the construction of a power plant, in order to ensure the cleanliness of the construction environment, it is usually necessary to configure dust suppression devices, which are often achieved through small fog cannon vehicles in actual construction.

[0003] The utility model with the authorization publication number CN213590015U provides a dust reduction device for power plant construction. Through the control components set up, the diversion pipe can be driven to swing back and forth autonomously, thereby increasing the dust reduction range and greatly improving the dust reduction efficiency.

[0004] However, in the above patent, if the electrical appliances on the seat are connected to an external power transmission line, the movement range of the dust suppression device will be limited. If a battery is installed on the seat to power the electrical appliances, the use time of the dust suppression device will be greatly limited. Therefore, when the above device is used for long-term spray dust suppression in a large dust area, it has the shortcomings of a small movable range or a short spraying time. The water mist of the nozzle can be sprayed in a small range, and the use is relatively limited. For this reason, we propose a dust suppression device for power plant environmental engineering.

[0030] The working principle and use process of the utility model are as follows: when the device is used and a dust reduction work in a larger range is required, the user starts the electric telescopic rod 32, and the electric telescopic rod 32 is extended to drive the linkage plate 29 to move vertically upward, and the two lifting plates 28 respectively drive the two wheel frames 23 and the two guide wheels 26 to move vertically upward synchronously, until the connecting shaft 24 drives the fourth bevel gear 25 to move up and mesh with the third bevel gear 22, and then the user starts the water pump 18 to inject the water in the water storage tank 17 into the fork joint 16, and the water is then injected into the interior of the two nozzles 12 through the two hoses 15 and the two hard pipes 13 in succession, and is sprayed out from the nozzles 12, and the user then pushes the dust reduction device to move in the dust dispersion area. In this process, the two guide wheels 26 drive the connecting shaft 24 and the fourth bevel gear 25 to rotate, and the meshing transmission of the fourth bevel gear 25 and the third bevel gear 22 makes the transmission shaft 20 drive the second bevel gear 21 to rotate, and the motor 3 is a hoop-free motor.

Through the meshing transmission of the rack 9 and the half gear 11, the two nozzles 12 swing synchronously, expanding the coverage of the water mist sprayed by the nozzle 12, thereby increasing the dust settling range of the water mist. The user pushes the dust suppression device to move continuously until the dust in a large range is fully settled. In this process, the motor 3 does not need to be powered on to run, saving electric energy, extending the discharge time of the battery 30, and thereby extending the working time of the dust suppression device. When only a small-scale local construction location needs to be dusted, the dust suppression device is stopped near the construction site, the electric telescopic rod 32 is started to move the linkage plate 29 downward and reset, the third bevel gear 22 is disengaged from the fourth bevel gear 25, and the motor 3 and the water pump 18 are started, so that the nozzle 12 sprays and settles the dust within the local construction range.
