In the initial state, the extension tube 6 is in the contraction state, and the elastic rope 5 is in the normal state; if meet the windy weather and lead to the dust to pile up fast at camera lens 2 surface in long-time measurement process, the staff need clear up camera lens 2 and just can continue to measure work, staff press switch 14 this moment, air pump 13 circular telegram and absorb the inside gas of casing 1, consequently be in the negative pressure state in casing 1, casing 1 absorbs the air from the external world this moment, and the inspiratory clean gas that is of air pump 13 under first filter screen 16's effect, the effect that prevents that the dust from getting into casing 1 inside and causing the influence to electronic component has been played.
During the operation of the air pump 13, the air discharged from the air pump 13 flows into the telescopic pipe 6 along the exhaust pipe 15, and since the diameter of the exhaust pipe 15 is larger than that of the through hole 10, part of the air flow flowing out of the exhaust pipe 15 passes through the through hole 10, and the other part of the air flow impacts the top wall of the slider 4, when the top wall of the slider 4 is impacted by the air flow, the slider 4 moves downwards, and the elastic rope 5 is stretched and has a restoring tendency.
In the process that the sliding block 4 moves downwards, the sliding block 4 drives the mounting rod 7 to move together with the hairbrush 8, so that dust on the surface of the lens 2 can be cleaned through the hairbrush 8, and in the process, air flow passing through the through hole 10 sequentially passes through the first cavity 9 and the second cavity 11 and then is discharged from the communicating groove 12, so that the telescopic tube 6 can be in a constant pressure state, and the effect of preventing the telescopic tube 6 from being burst is achieved.

When the air pump 13 absorbs air from the outside through the first filter screen 16, the air with lower outside temperature enters the shell 1 through the first filter screen 16, and at the moment, the low-temperature air flow contacts with the electronic element in the shell 1, and absorbs heat generated by the electronic element under the action of heat exchange, so that the electronic element is ensured to work in a normal temperature range, the probability of damage of the electronic element due to overhigh temperature is reduced, and the effect of prolonging the service life of the electronic element is achieved; after the measurement is finished, the worker presses the switch 14, the air pump 13 is powered off, and therefore the elastic rope 5 with the restoring tendency pulls the sliding block 4 to move upwards, and the function of preparing for the next work is achieved.
Specifically, as shown in fig. 5 and 7, the mounting rod 7 includes a rotating shaft 701 and a barrel-shaped second filter screen 702, the rotating shaft 701 is rotatably connected with the slider 4, the second filter screen 702 is movably sleeved on the rotating shaft 701, the brushes 8 are uniformly and fixedly mounted on the side wall of the second filter screen 702, an exhaust groove 17 matched with the communicating groove 12 is formed in the top wall of the second filter screen 702, and a driving mechanism for driving the second filter screen 702 to rotate is arranged on the guide rail 3.
The driving mechanism comprises a gear 18 fixedly sleeved on the outer wall of the second filter screen 702, and tooth grooves 19 meshed with the gear 18 are uniformly formed in the inner side wall of the guide rail 3.
Because the gear 18 is engaged with the tooth groove 19, in the process that the sliding block 4 drives the rotating shaft 701 to move downwards, the gear 18 drives the second filter screen 702 to rotate, in the rotating process of the second filter screen 702, dust on the surface of the lens 2 is cleaned by the brush 8, then the brush 8 continuously rotates, in the rotating process of the brush 8, dust on the brush 8 is shaken off, because the brush 8 continuously rotates, and the brush 8 is uniformly arranged on the side wall of the second filter screen 702, therefore, the dust shaken off on the brush 8 in front is pushed by the brush 8 rotating subsequently, when the brush 8 pushes the dust to rotate to the surface of the communicating groove 12, air flow blown out of the communicating groove 12 impacts the brush 8, so that the dust in the brush 8 can be cleaned, the dust on the brush 8 is prevented from being attached to the surface of the lens 2 again, and the effect of cleaning the lens 2 by the brush 8 is ensured.
Since the second filter 702 has a plurality of holes on its surface, the airflow discharged from the communicating groove 12 can still form an airflow film during the rotation of the second filter 702, thereby ensuring that the cleaned surface of the lens 2 can form an airflow protection film.
Specifically, as shown in fig. 6, the bottom ends of the two guide rails 3 are horizontally and fixedly mounted with a storage tube 20 with an open top end, the guide rail 3 is provided with a guide groove 21 matched with the guide rail 3, and the guide groove 21 is located between the tooth socket 19 and the bottom wall of the storage tube 20.
A supporting plate 22 is movably disposed in the accommodating tube 20, a side wall of the supporting plate 22 away from the lens 2 is an inclined surface, and a spring 23 is fixedly installed between the supporting plate 22 and the accommodating tube 20.
In the initial state, under the action of the spring 23, the top end of the supporting plate 22 is located outside the accommodating tube 20, so when the communicating groove 12 on the bottom wall of the mounting rod 7 exhausts air outwards, and the air flow passes through the exhaust groove 17 and impacts the supporting plate 22, the air flow will impact the inclined side wall surface of the supporting plate 22 on the side far away from the lens 2, at this time, under the drainage action of the inclined surface, the direction of the air flow will be changed, so that the air flow carrying dust can be prevented from entering the accommodating tube 20, and the effect of ensuring that the mounting rod 7 can enter the inside of the accommodating tube 20 is achieved.
During the process that the sliding block 4 moves downwards along the guide rail 3, the gear 18 gradually moves to the bottom end of the tooth slot 19, after the gear 18 reaches the bottom end of the tooth slot 19, the gear 18 enters the guide groove, and the gear 18 does not rotate any more and slides downwards along the guide groove; and in the process that the gear 18 moves down along the flow guide groove, the bottom wall of the mounting rod 7 is in contact with the side wall of the support plate 22, at this time, the mounting rod 7 applies downward pressure to the support plate 22, because the pressure of the mounting rod 7 to the support plate 22 is greater than the elastic force of the spring 23, the support plate 22 moves down under the action of the pressure, when the gear 18 slides to the bottom end of the flow guide groove, the mounting rod 7 enters the accommodating pipe 20, at this time, the side wall of the accommodating pipe 20 presses the brush 8, so the brush 8 is clamped between the side wall of the accommodating pipe 20 and the outer wall of the second filter screen 702, so that the communicating groove 12 on the bottom wall of the mounting rod 7 can be blocked, therefore, the air flow in the second cavity 11 can only flow out from the communicating groove 12 on the top wall of the mounting rod 7, because the number of teeth of the gear 18 is equal to the number of the tooth grooves 19, when the slider 4 moves to the bottom end of the guide rail 3, the air discharge groove 17 on the second cavity 702 and the communicating groove 12 are in the same vertical plane, thereby increasing the air flow rate and increasing the air flow film, namely, and playing a role of ensuring that the impact force for blowing dust can be blown off the filter screen.
Specifically, as shown in fig. 6, the magnet 24 is fixedly embedded in the bottom wall of the receiving tube 20, and the second filter 702 is made of a ferrous material.
In the process that the mounting rod 7 enters the accommodating pipe 20, the second filter screen 702 is attracted by the magnet 24, at this time, under the combined action of the attraction of the second magnet 24 and the impact force of the airflow on the slider 4, the mounting rod 7 can be prevented from being pushed upwards by the airflow discharged from the communicating groove 12 on the bottom wall of the mounting rod 7, the mounting rod 7 can be ensured to be positioned in the accommodating pipe 20 in the working process, and the effect of preventing the mounting rod 7 from moving up and down on the surface of the lens 2 to influence the measurement is achieved.
Specifically, as shown in fig. 4, a guide plate 25 made of a heat insulating material is fixedly and obliquely installed on the top wall of the housing 1, and an included angle between the guide plate 25 and the top wall of the housing 1 is 60 ° to 80 °.
The dust blown upwards by the air flow blown out from the communicating groove 12 is under the combined action of the external wind power and the air flow discharged from the communicating groove 12, the dust flows along the surface of the guide plate 25 along with the air flow, and at the moment, the dust has the tendency of moving upwards in an inclined manner, so that the dust can be transferred to the space far away from the shell 1, and the function of preventing the dust from entering the eyes of workers using the instrument is achieved; and when the air current breaks away from contact with the guide plate 25, the air current still keeps the upward flow trend of slope, can shift the air current that has absorbed the heat, prevents that the higher gas of temperature from flowing along the roof of casing 1, has played the effect of preventing the temperature of hot gas flow from transmitting to casing 1.
The invention also provides a surveying and mapping method suitable for the multifunctional geographical surveying and mapping equipment, which comprises the following steps;
s1, pressing a switch 14, wherein air flow discharged from an air pump 13 flows into an extension pipe 6 along an air exhaust pipe 15;
s2, the airflow entering the extension tube 6 impacts the top wall of the sliding block 4, the sliding block 4 drives the mounting rod 7 and the hairbrush 8 to move downwards, and the hairbrush 8 scrapes on the surface of the lens 2 to clean dust;
s3, the air flow in the extension tube 6 passes through the through hole 10, the first cavity 9 and the second cavity 11 and is discharged from the communicating groove 12, and the air flow discharged from the communicating groove 12 forms an air flow barrier on the surface of the lens 2 to prevent dust from being attached to the surface of the lens 2 again;
s4, the sliding block 4 moves to the bottom end of the guide rail 3, the mounting rod 7 enters the containing pipe 20, the communicating groove 12 in the bottom wall of the mounting rod 7 is blocked, the impact force of airflow flowing out of the communicating groove 12 in the top wall of the mounting rod 7 is increased, and when the dust flows towards the surface of the lens 2, the dust can be blown away by the airflow barrier.
The working principle is as follows: in the initial state, the extension tube 6 is in the contraction state, and the elastic rope 5 is in the normal state; if meet the windy weather and lead to the dust to pile up fast at camera lens 2 surface in long-time measurement process, the staff need clear up camera lens 2 and just can continue to measure work, staff press switch 14 this moment, air pump 13 circular telegram and absorb the inside gas of casing 1, consequently be in the negative pressure state in casing 1, casing 1 absorbs the air from the external world this moment, and the inspiratory clean gas that is of air pump 13 under first filter screen 16's effect, the effect that prevents that the dust from getting into casing 1 inside and causing the influence to electronic component has been played.
During the operation of the air pump 13, the air discharged from the air pump 13 flows into the telescopic tube 6 along the air discharge pipe 15, and since the diameter of the air discharge pipe 15 is larger than that of the through hole 10, a part of the air flow flowing out of the air discharge pipe 15 passes through the through hole 10, another part of the air flow impacts the top wall of the slider 4, and when the top wall of the slider 4 is impacted by the air flow, the slider 4 moves downwards, and the elastic rope 5 is stretched and has a restoring tendency.
In the process that the sliding block 4 moves downwards, the sliding block 4 drives the mounting rod 7 to move together with the hairbrush 8, so that dust on the surface of the lens 2 can be cleaned through the hairbrush 8, and in the process, air flow passing through the through hole 10 sequentially passes through the first cavity 9 and the second cavity 11 and then is discharged from the communicating groove 12, so that the telescopic tube 6 can be in a constant pressure state, and the effect of preventing the telescopic tube 6 from being burst is achieved.
The airflow discharged from the communicating groove 12 forms a layer of airflow film on the surface of the lens 2, so when dust approaches the surface of the lens 2, the dust can firstly enter the airflow film, the airflow in the second cavity 11 is discharged from the communicating grooves 12 on the top wall and the bottom wall of the mounting rod 7, and then an airflow barrier is formed, so that the dust can be prevented from continuously attaching to the surface of the lens 2, the effect of ensuring that the hairbrush 8 can clean the dust on the surface of the lens 2 is achieved, and then the dust can be prevented from attaching to the surface of the lens 2 again along with the airflow film being blown away, and the effect of ensuring the lens 2 to be clear is achieved; therefore, under the combined action of the hairbrush 8 and the communicating groove 12, the cleaning frequency of the lens 2 is reduced, the abrasion degree of the lens 2 is reduced, and the effect of reducing the damage probability of the lens 2 is achieved.
When the air pump 13 absorbs air from the outside through the first filter screen 16, the air with lower outside temperature enters the shell 1 through the first filter screen 16, and at the moment, the low-temperature air flow contacts with the electronic element in the shell 1, and absorbs heat generated by the electronic element under the action of heat exchange, so that the electronic element is ensured to work in a normal temperature range, the probability that the electronic element is damaged due to overhigh temperature is reduced, and the effect of prolonging the service life of the electronic element is achieved; after the measurement is finished, the worker presses the switch 14, and the air pump 13 is powered off, so that the elastic rope 5 with the restoring tendency pulls the sliding block 4 to move upwards to prepare for the next work.
Because the gear 18 is engaged with the tooth groove 19, in the process that the sliding block 4 drives the rotating shaft 701 to move downwards, the gear 18 drives the second filter screen 702 to rotate, in the rotating process of the second filter screen 702, dust on the surface of the lens 2 is cleaned by the brush 8, then the brush 8 continuously rotates, in the rotating process of the brush 8, dust on the brush 8 is shaken off, because the brush 8 continuously rotates, and the brush 8 is uniformly arranged on the side wall of the second filter screen 702, therefore, the dust shaken off on the brush 8 in front is pushed by the brush 8 rotating subsequently, when the brush 8 pushes the dust to rotate to the surface of the communicating groove 12, air flow blown out of the communicating groove 12 impacts the brush 8, so that the dust in the brush 8 can be cleaned, the dust on the brush 8 is prevented from being attached to the surface of the lens 2 again, and the effect of cleaning the lens 2 by the brush 8 is ensured.
Since the second filter 702 has a plurality of holes on its surface, the airflow discharged from the communicating groove 12 can still form an airflow film during the rotation of the second filter 702, thereby ensuring that the cleaned surface of the lens 2 can form an airflow protection film.
In the initial state, under the action of the spring 23, the top end of the supporting plate 22 is located outside the accommodating tube 20, so when the communicating groove 12 on the bottom wall of the mounting rod 7 exhausts air outwards, and the air flow passes through the exhaust groove 17 and impacts the supporting plate 22, the air flow will impact the inclined side wall surface of the supporting plate 22 on the side far away from the lens 2, at this time, under the drainage action of the inclined surface, the direction of the air flow will be changed, so that the air flow carrying dust can be prevented from entering the accommodating tube 20, and the effect of ensuring that the mounting rod 7 can enter the inside of the accommodating tube 20 is achieved.
During the process that the sliding block 4 moves downwards along the guide rail 3, the gear 18 gradually moves to the bottom end of the tooth groove 19, and after the gear 18 reaches the bottom end of the tooth groove 19, the gear 18 enters the diversion groove, and the gear 18 does not rotate any more and slides downwards along the diversion groove; and in the process that the gear 18 moves down along the flow guide groove, the bottom wall of the mounting rod 7 is in contact with the side wall of the support plate 22, at this time, the mounting rod 7 applies downward pressure to the support plate 22, because the pressure of the mounting rod 7 to the support plate 22 is greater than the elastic force of the spring 23, the support plate 22 moves down under the action of the pressure, when the gear 18 slides to the bottom end of the flow guide groove, the mounting rod 7 enters the accommodating pipe 20, at this time, the side wall of the accommodating pipe 20 presses the brush 8, so the brush 8 is clamped between the side wall of the accommodating pipe 20 and the outer wall of the second filter screen 702, so that the communicating groove 12 on the bottom wall of the mounting rod 7 can be blocked, therefore, the air flow in the second cavity 11 can only flow out from the communicating groove 12 on the top wall of the mounting rod 7, because the number of teeth of the gear 18 is equal to the number of the tooth grooves 19, when the slider 4 moves to the bottom end of the guide rail 3, the air discharge groove 17 on the second cavity 702 and the communicating groove 12 are in the same vertical plane, thereby increasing the air flow rate and increasing the air flow film, namely, and playing a role of ensuring that the impact force for blowing dust can be blown off the filter screen.
In the process that the mounting rod 7 enters the accommodating pipe 20, the second filter screen 702 is attracted by the magnet 24, at this time, under the combined action of the attraction of the second magnet 24 and the impact force of the airflow on the slider 4, the mounting rod 7 can be prevented from being pushed upwards by the airflow discharged from the communicating groove 12 on the bottom wall of the mounting rod 7, the mounting rod 7 can be ensured to be positioned in the accommodating pipe 20 in the working process, and the effect of preventing the mounting rod 7 from moving up and down on the surface of the lens 2 to influence the measurement is achieved.
The dust blown upwards by the air flow blown out from the communicating groove 12 is under the combined action of the external wind power and the air flow discharged from the communicating groove 12, the dust flows along the surface of the guide plate 25 along with the air flow, and at the moment, the dust has the tendency of moving upwards in an inclined manner, so that the dust can be transferred to the space far away from the shell 1, and the function of preventing the dust from entering the eyes of workers using the instrument is achieved; and when the air current breaks away from contact with the guide plate 25, the air current still keeps the upward flow trend of slope, can shift the air current that has absorbed the heat, prevent that the higher gas of temperature from flowing along casing 1 roof, has played the effect of preventing the temperature of hot gas flow from transmitting to casing 1.
