Description

Technical Field

[0001] The invention relates to the technical field of environmental monitoring equipment, and in particular to a mobile dust monitoring and control device for a collapsed land control construction site. Background Art

[0002] The treatment of subsidence usually involves a lot of earthwork operations, such as excavation and backfilling. A lot of dust will be generated during the operation, which will not only threaten the health of construction workers, but also have adverse effects on the surrounding environment. Therefore, it is necessary to use dust monitoring equipment to monitor the environment, so as to detect dust pollution problems in time, so that countermeasures can be taken quickly to prevent the spread of pollution. This can not only ensure the safety and environmental protection of the construction site, but also avoid social problems and legal disputes caused by dust pollution.

[0003] Laser scattering is a widely used technology that can measure the intensity of scattered light. The dust monitoring device can calculate the concentration of dust particles and transmit the data to the monitoring center to achieve remote monitoring and management of the data.

[0004] Traditional dust monitoring devices use their good mobility to detect and collect data in a large area. However, when the monitored data exceeds the set threshold concentration, they cannot take effective measures to deal with the area where the particle concentration exceeds the limit. They also need to manually receive the data information and take the equipment for cleaning, which is time-sensitive. Manual operation is too labor-intensive and cannot be handled at any time. Summary of the invention

[0005] In order to solve the technical problem that the dust monitoring device proposed in the background technology only monitors the environment but cannot simultaneously control it, and also requires manual control resulting in poor timeliness, the present invention proposes a mobile dust monitoring and control device for a collapsed land control construction site.

[0006] The present invention adopts the following technical scheme: a mobile dust monitoring and control device for a subsidence treatment construction site comprises:

[0007] A mobile chassis, which provides mobility for the device;

[0008] A dust collection shell, the dust collection shell is installed on the top of the mobile chassis;

[0009] A dust reduction shell, which is installed on the top of the dust collection shell, and a water tank is arranged in the dust reduction shell;

[0010] A power assembly, wherein the power assembly is installed in the dust collection housing;

[0011] Monitoring equipment, the monitoring equipment consists of two groups and is symmetrically installed on the outer wall of the dust collection housing;

[0012] A dust suction mechanism, which is installed in the dust suction housing, and includes a negative pressure component, a cleaning component and a spray component, wherein the negative pressure component, the cleaning component and the spray component are each in two groups;

[0013] A dust reduction mechanism is installed in the water tank.

[0014] Through the above technical scheme, the mobile chassis is used to drive the entire device to move, and the monitoring equipment set at both ends is used for real-time monitoring. When the dust concentration in the air is detected to reach the set threshold, the data is transmitted and the power component inside the device is driven to drive the entire device to operate, so that the dust reduction mechanism on the top can perform rotational atomization spraying of the internal water body, and at the same time, the dust suction mechanisms on both sides will perform negative pressure suction of the dust in the area and collect it in the collection box, and the spray component can be used to prevent the absorbed dust from overflowing. The monitoring equipment is used for real-time monitoring during treatment. When the dust concentration in the air drops to the set standard, the power component is turned off, and cyclic monitoring is performed under the drive of the mobile chassis.

[0015] As a further improvement of the above scheme, the negative pressure component includes a dust suction cavity, which is divided into two groups and symmetrically fixed on both sides of the dust suction shell.

[0021] Through the above technical scheme, the filter screen is connected by the sleeve for reciprocating horizontal movement. At the same time, the vertical sliding connection between the vertical groove and the protrusion 2 can ensure that the horizontal plate 2 can move vertically along the guide groove on the outside of the filter screen and can also move relatively horizontally under the sliding connection with the guide groove. The filter screen attachment can be cleaned and collected in the collection box through the discharge port.

[0022] As a further improvement of the above scheme, the spray assembly includes two atomizing nozzles symmetrically installed at the bottom of the water tank, the two groups of atomizing nozzles are connected to the water tank, the atomizing nozzles are in a trumpet shape with the opening facing downward, an inner plate is fixedly connected inside the atomizing nozzles, the bottom end of the inner plate is abutted against a baffle, the baffle slides horizontally inside the atomizing nozzles for opening and closing the atomizing nozzles, one side of the baffle is fixedly connected to a connecting plate, the other side of the connecting plate is fixedly connected to a spring one, the other side of the spring one is fixedly connected to a fixing plate, the fixing plate is fixedly installed at the bottom of the water tank, and the two groups of baffles are fixedly connected to side plates on the sides close to each other.

[0066] At the same time, since the bottom end of the sleeve 214 is connected to the vertical plate 215, and the outer plate 216 is connected by the vertical plate 215, the collection box 217 installed inside the outer plate 216 can shake the dust collected inside as the sleeve 214 moves back and forth, so as to increase the effective storage space.

[0067] Embodiment 2:
