The air inlet bin 309 is connected with the top of the dust removing bin 301 through an air inlet pipe 308. In order to prevent dust from flowing back from the dust removing bin 301 to the air inlet bin 309, a partition filter screen 312 is arranged inside the dust removing bin 301, and the lower end of the dust suction pipe 10 extends into the dust removing bin 301 below the partition filter screen 304.
The exhaust bin 310 is connected with the dust removal water tank 4 through a first exhaust pipe 6, and a first one-way exhaust valve 7 is arranged on the first exhaust pipe 6. The first one-way exhaust valve 7 has two functions, on one hand, the opening and the closing of the first exhaust pipe 6 can be controlled; on the other hand, in the state where the first exhaust pipe 6 is in circulation, air can only enter the first exhaust pipe 6 from the exhaust bin 310, and no backflow of gas occurs.
The exhaust bin 310 is further connected with a second exhaust pipe 8, and a second one-way exhaust valve 9 is arranged on the second exhaust pipe 8. The second one-way exhaust valve 9 allows gas to flow only from the exhaust bin 310 into the second exhaust pipe 8 without backflow of gas.

The dust which is absorbed and settled can be prevented from entering the return pipe 13 to pollute the water stored in the dust removal water tank 4.
The upper end of the dust removal water tank 4 is connected with the water supply tank 5 through a water supply pipe 14. The makeup water tank 5 may supply makeup water to the dust removal water tank 4. The water supply pipe 14 is further provided with a check valve (not shown) which only allows water to enter the dust removal water tank 4 from the water supply tank 5 but does not allow water to flow in the reverse direction.
The working principle of the device is as follows:
in the working process of the surveying and mapping device, the dust removal mechanism 3 is always in a working state. The dust removing mechanism 3 of the present invention has two operation modes, i.e., a dust removing mode and a pipe cleaning mode. Specifically, the method comprises the following steps:
firstly, a dust removal mode:
the linear motor is activated to reciprocate the push piston 306 along the cylinder 305. At this time, the first electromagnetic valve 12 is opened, the first one-way exhaust valve 7 and the second electromagnetic valve 16 are closed, and the dedusting water tank 4 and the makeup water tank 5 are filled with water.
As shown in fig. 2, when the piston 306 moves to the left along the cylinder 305, the volume of the exhaust bin 310 increases, a negative pressure is formed in the exhaust bin, the gas in the inlet bin 309 can enter the exhaust bin 310 from the one-way inlet valve 307 at the middle part of the piston 306, at this time, no air pressure is below the dust exhaust bottom cover 304 enough to cover the dust exhaust port 314 upwards, dust lumps settled by moisture in the dust exhaust bin 301 can fall off the machine body 1 along the dust exhaust port 314, the load of the surveying and mapping device is reduced, and the dust does not need to worry about flying again because it has settled.
As shown in fig. 3, when the piston 306 moves to the right along the cylinder 305, the volume of the exhaust chamber 310 decreases, the gas in the exhaust chamber 310 is squeezed and exhausted from the second exhaust pipe 8, the outlet of the second exhaust pipe 8 has sufficient air pressure strength to blow the dust exhaust bottom cover 304 upwards, and the dust exhaust port 314 arranged below the dust removal chamber 301 is momentarily blocked by the dust exhaust bottom cover 304.
Meanwhile, in the process that the piston 306 moves towards the exhaust bin 310, negative pressure is formed inside the air inlet bin 309, the dust removal bin 301 is connected with the air inlet bin 309 through the air inlet pipe 308, and the dust discharge port 314 of the dust removal bin 301 is blocked, so that the inside of the dust removal bin 301 is in a sealed negative pressure space. The dust removal bin 301 will be through taking out dirt pipe 10 and take out dirt from taking out dirt mouth 303, take out dirt mouth 303 and will distribute and take away at surveying instrument 2 dust all around, survey and drawing to the more regional geographic information of dust, have fabulous dust removal effect.
The dust enters the dust removing chamber 301 below the partition filter screen 312 through the dust suction pipe 10, and then is retained in the space below the partition filter screen 304. The water in the dedusting water tank 4 enters the dedusting bin 301 in the negative pressure environment through the water spraying pipe 11, and is sprayed on the dust in the dedusting bin 301 under the action of the water spraying head, so that the dust in the dedusting bin 301 is settled, and the dust in the dedusting bin 301 is prevented from forming flying dust due to gas flow.
In addition, since the water in the dust-removing water tank 4 is reduced, a negative pressure space is formed inside the dust-removing water tank 4. The water settled and collected in the dust discharge port 314 below the dust removing bin 301 (at this time, the dust discharge bottom cover 304 seals the dust discharge port 314, and the water does not flow downward) can be recycled to the dust removing water tank 4 through the water return pipe 13. On the one hand, the water-saving device is favorable for saving water resources, and on the other hand, the water-carrying load of the surveying and mapping device for dust removal can be reduced.
The pressure difference created in the dust-removing water tank 4 causes the make-up water in the make-up water tank 5 to enter the dust-removing water tank 4 through the make-up water pipe 14, since part of the water used for settling the dust is not sufficiently recycled.
The dust discharging bottom cover 304 makes intermittent fluctuation movement all the time in the process, so that the shaking and dust falling in the dust removing bin 301 can be promoted, and the dust discharging efficiency can be improved.
II, a pipeline cleaning mode:
the dust removing mechanism 3 is used for a long time, dust is easily deposited in the dust suction pipe 10 and the water return pipe 13, so that the normal operation of the device is influenced, and the part of the pipeline needs to be cleaned regularly. Specifically, the method comprises the following steps:
on the basis of the work of the dust removal mode, the first one-way exhaust valve 7 and the second electromagnetic valve 16 are opened, and the first electromagnetic valve 12 is closed, and the specific implementation mode is as follows:
when the piston 306 moves to the right along the cylinder 305 as shown in fig. 4, the gas in the exhaust chamber 310 is pushed out from the second exhaust pipe 8 and the first exhaust pipe 6, and since the gas pressure previously and completely supplied to the second exhaust pipe 8 is partially shared by the first exhaust pipe 6, the gas flow at the lower part of the dust exhaust bottom cover 304 is insufficient to make the dust exhaust port 314 in a closed state. The water entering the dust removal water tank 4 from the first exhaust pipe 6 is extruded by the air pressure of the dust removal water tank 4 and enters the flushing pipe 15 through the water spraying pipe 11 and the two-way 17, and the dust extraction pipe 10 is flushed from top to bottom, so that the dust is prevented from being blocked in the pipeline;
at the same time, the water in the dust removing water tank 4 is extruded by the air pressure to flow out of the return pipe 13, and the mud which may be settled in the return pipe 13 is washed. The dirty water with the dust is discharged directly through the dust outlet 314. The intermittent switching of the pipeline cleaning mode and the dust removal mode can ensure the stable work of the dust removal mechanism 3, improve the surveying and mapping environment, save resources and improve the surveying and mapping accuracy.
Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
