Description

Technical Field

[0001] The utility model relates to the technical field of road dust reduction, in particular to a spray device for dust reduction. Background Art

[0002] Large open-pit mines mostly use standard-gauge railways for transportation, while small and medium-sized open-pit mines and quarries mostly use narrow-gauge railways or human-powered carts, and winches or stepless rope hoists are used for combined transportation on slopes. The main vehicle for road transportation in open-pit mines is dump trucks, while small mines and quarries also often use tractors, motorized tricycles, and even animal-powered vehicles and human-powered vehicles.

[0003] During mining and transportation, dump trucks transport stones from the mining area to the coarse crushing unloading platform, which easily generates a lot of dust. Currently, sprinkler trucks are mostly used to spray water to reduce dust, but the dust reduction effect is not ideal. The dust reduction effect after the sprinkler truck operation is short-lived, and the operation frequency and operation time period need to be manually controlled, which consumes manpower costs and will cause certain obstacles to the dump trucks operating on the road.

[0037] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the technical solution of the present utility model is further described below in conjunction with specific embodiments.

[0038] Embodiment 1:

A sliding cavity that cooperates with the second rotating shaft 17 is provided inside the adjustment plate 11. The second rotating shaft 17 passes through the sliding cavity and is slidably connected to the adjustment plate 11.

[0041] When the electric telescopic rod 15 contracts downward, the first rotating shaft 14 at the top of the electric telescopic rod 15 drives the adjustment plate 11 to rotate, and the angle between the adjustment plate 11 and the side plate of the mounting frame 1 becomes larger. At the same time, the first rotating shaft 14 will also pull the end of the adjustment plate 11 to move downward, and the sliding cavity of the adjustment plate 11 slides on the second rotating shaft 17, so that the second rotating shaft 17 generates relative sliding in the sliding cavity along the axial direction of the adjustment plate 11.

[0042] In the present embodiment, in addition to arranging a single-sided adjustment plate 11, a double-sided adjustment plate 11 can also be arranged. A sliding cavity is provided in each of the two adjustment plates 11. The rotating seat has a first rotating seat 12 and a second rotating seat 13. Second rotating shafts 17 are installed on the tops of the two side plates. The first rotating shaft 14 is rotatably connected to the adjustment plate 11 via the first rotating seat 12.

[0045] The dust monitoring component 20 has a dust detection sensor and a controller. The dust monitoring component 20 is installed on the bottom plate of the mounting frame 1. The dust detection sensor is connected to the controller circuit. The electric telescopic rod 15, the steering motor 16, and the high-pressure water pump 6 are all connected to the controller for communication. The dust detection sensor is used to collect TSP detection information in the air and transmit it to the controller. The controller is preset with a TSP threshold. If the received TSP detection information does not meet the TSP threshold, the controller starts the device to reduce dust. In this embodiment, the preset TSP threshold is 300 micrograms / cubic meter. If the TSP detection information is greater than or equal to 300 micrograms / cubic meter, the controller starts the device to spray dust reduction, thereby realizing automatic spraying and dust reduction of the device, without the need for manual control of the operating period and operating frequency of the spraying device.

[0046] The dust monitoring component 20 also has a monitoring camera, which is used to monitor the dust reduction conditions on the transport road and the spraying device. The monitoring camera and the controller are both connected to the information monitoring and management platform. The monitoring camera transmits the monitoring video to the information monitoring and management platform via wireless communication. The controller transmits the received TSP detection information to the information monitoring and management platform in real time wirelessly. The information monitoring and management platform stores and processes the monitoring video and TSP detection information to achieve real-time monitoring of the dust conditions on the transport road. The information monitoring and management platform can also further analyze the collected TSP detection information and optimize the TSP threshold through data analysis, so that a suitable TSP threshold is preset in the controller. The suitable TSP threshold can ensure that the dust particles in the air on the transport road are within a reasonable range and play a role in saving water.

[0047] The photovoltaic assembly has a solar photovoltaic panel 19 and a battery 21. A positioning plate 18 is connected to the support plate 2 of the mounting frame 1, and a solar photovoltaic panel 19 is installed on the positioning plate 18.

The solar photovoltaic panel 19 can convert the absorbed solar energy into electrical energy and store it in the battery 21.

[0048] The spray device can be installed at intervals along both sides of the transport road according to its actual spraying range. When the TSP concentration in the air on the transport road is higher than the preset TSP threshold, the spray device will start spraying to reduce dust, thereby controlling the dust content in the air on the transport road to be within a reasonable range.

[0049] Embodiment 2:

[0050] The difference between this embodiment and the above embodiment lies in that the connection method between the adjustment plate 11 and the side plate of the mounting frame 1 is different, and the two ends of the top of the side plate are respectively connected with a part of the fixed shaft, and the side walls on both sides of the adjustment plate 11 are provided with sliding grooves for the fixed shaft to slide, and the end of the adjustment plate 11 is rotatably connected to the first rotating shaft 14 via a rotating seat, and the fixed shaft is engaged in the sliding grooves on both sides of the adjustment plate 11, and the fixed shaft can passively slide along the sliding grooves.

[0051] When the electric telescopic rod 15 changes its telescopic state, the electric telescopic rod 15 drives the adjustment plate 11 via the first rotating shaft 14, and the adjustment plate 11 rotates around the first rotating shaft 14. At the same time, the adjustment plate 11 is pulled by the first rotating shaft 14, so that the sliding groove on the adjustment plate 11 slides on the fixed shaft.

[0052] The implementation principle of a spray device for dust reduction in the present application is:

[0053] The dust detection sensor collects the TSP detection concentration in the air of the transport road, and the controller compares the TSP detection concentration with 300 micrograms / cubic meter. If the TSP detection concentration is higher than 300 micrograms / cubic meter, the controller activates the spraying device to spray dust on the transport road;

[0054] The controller controls the electric telescopic rod 15 to retract and descend, and the electric telescopic rod 15 drives the adjustment plates 11 on both sides to rotate, the angle between the adjustment plates 11 and the side walls of the mounting frame 1 increases, and the atomizing nozzle 8 on the adjustment plate 11 faces the air of the transport road, so that the spraying angle of the device becomes larger;

[0055] The controller controls the high-pressure water pump 6 to pump water from the water tank 3. Under the cooperation of the pressurization of the high-pressure water pump 6 and the atomization of the atomizing nozzle 8, the high-pressure water flow is sprayed out in the form of atomization, and the spraying range is relatively far;

[0056] The controller controls the output end of the steering motor 16 to rotate, and controls the steering motor 16 to rotate back and forth within the target spraying range according to the required spraying position. The output end of the steering motor 16 drives the turntable 22 to rotate, and the turntable 22 drives the mounting frame 1 to rotate. The atomizing nozzle 8 on the side wall of the mounting frame 1 and the adjustment plate 11 atomizes and sprays during the rotation process, thereby forming a large-area coverage spray on the transport road. When the steering motor 16 continuously rotates circumferentially in a single direction, the spray coverage area caused at this time is the largest, so that the water mist is fully in contact with the dust in the air of the transport road, which can ensure a better spray dust reduction effect.

[0057] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
