Description

Aerodynamic culvert structure for box culvert detection

Technical Field

The utility model belongs to the technical field of the facility of sartorius is examined to underground box culvert, concretely relates to aerodynamic culvert structure for box culvert detects.

Background

In recent years, urban waterlogging is one of the important problems facing the development of cities in China at all times when most cities in China are exposed to heavy rain and waterlogging.

The urban drainage pipe discharges more and more waste water and waste in all years, and the waste water and waste are corrosive, so that various functional and structural damages such as blockage, leakage and the like of the urban drainage pipe are caused.

Therefore, drainage pipelines must be detected in time, and more or less rain sewage exists in the drainage pipelines, so that the drainage pipelines can only detect the close-range internal conditions if the drainage pipelines are detected by adopting a traditional periscope mode, and the shooting effect is poor due to the fact that the drainage pipelines are disturbed by water bodies.

If adopt traditional pipeline robot of crawling, then need block up water, cofferdam to the box culvert, take out the inside rain sewage of box culvert futilely or take out and carry out corresponding detection achievement after the low water level, earlier stage operation process is loaded down with trivial details, operates inconveniently.

At present, a section of detection robot on water is developed on traditional basis, and this detection robot on water includes the hull, and the afterbody of hull is provided with aerodynamic system, and aerodynamic system includes motor, support and screw, and the bottom and the hull welding of support, the top of support pass through the bolt fastening with the motor, and the output shaft and the screw of motor are fixed, give motor circular telegram starter motor, and the motor rotates and drives the screw and rotate and promote the hull and advance.

However, in the process of high-speed rotation of the propeller, air at the lower end of the wingtip of the propeller flows upwards from the periphery, so that the propeller does useless work, and the power of the propeller is reduced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an aerodynamic force duct structure for box culvert detects, it has solved the high-speed rotatory in-process of current screw, and the air of the wingtip lower extreme of screw upwards flows from the periphery for the screw is useless work, has reduced the problem of the power of screw.

The utility model aims at solving through the following technical scheme:

the utility model provides an aerodynamic duct structure for box culvert detects, this aerodynamic duct is including setting up the body at the hull afterbody, the body is interior mesoporous circular arc, this is provided with the frame of attenuating in the body, the frame of attenuating and this body coupling.

Further: the width of the periphery of the body from the top to the bottom is gradually reduced to form an arc shape.

Further: the width of the inner side of the body is gradually increased from inside to outside.

Further: the edge of the outer side air inlet on the periphery of the body is arc-shaped.

Further: the attenuating frame is in a cross shape.

Further: the attenuating frame is made of carbon fiber pipes.

Further: and the attenuating frame is externally coated with foam plastics.

Further: the foamed plastic is streamline.

Compared with the prior art, the utility model discloses the beneficial effect who has is:

by arranging the aerodynamic duct, the air at the lower end of the wingtip of the propeller is effectively prevented from flowing upwards from the periphery, the working environment of the propeller is improved, and the working efficiency of the propeller is increased;

the disturbance of the propeller airflow can be reduced by arranging the attenuating frame, and the stability of the propeller is improved.

Drawings

Fig. 1 is a schematic perspective view of the present invention;

fig. 2 is a working state diagram of the present invention.

Wherein: 1. a body; 11. a mesopore; 12. a buffering frame; 13. a foam.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings:

as shown in fig. 1 and 2, the aerodynamic culvert structure for box culvert detection comprises a body 1 arranged at the tail of a ship body, wherein the body 1 is an arc with an inner middle hole 11.

The width of the periphery of the body 1 from the top to the bottom is gradually reduced to form an arc shape.

The width of the inner side of the body 1 is gradually increased from inside to outside, and the edge of the outer side air inlet on the periphery of the body 1 is arc-shaped.

The body 1 is internally welded with a ballast 12, the ballast 12 is connected with the body 1, and the ballast 12 is made of carbon fiber pipes.

And the foam plastic 13 is externally applied to the attenuating frame 12, and the foam plastic 13 is streamline.

The working principle is as follows: through setting up the aerodynamic duct, the effectual air that has prevented screw wingtip lower extreme upwards flows from the periphery, improves the operational environment of screw, has increased the work efficiency of screw.

The disturbance of the propeller airflow can be reduced by arranging the attenuating frame 12, and the stability of the propeller is improved.
