Slot is embedded with sealing ring in annular groove, prevents leak, improves sealing performance.In other embodiments, the quantity of annular groove can be
One, three, four or five.
In the present embodiment, first spacer portion 121, the second spacer portion 161 and third spacer portion 103 are ring-type,
It is easy to process, and with the contact surface of thrust bearing is big, isolation effect is good.In other embodiments, spacer portion can for it is multiple not
Continuous block-shaped protrusion.
In the present embodiment, the first end cover 14 and the other end of inner cylinder 2 are connected by screw to, the first connector 8
Outer end face be connected by screw to second end cover 13, third end cap 20 and the end face of third connector 16 are connected by screw to,
Replacement easy to disassemble, and fastening effect is good.
In the present embodiment, the bracket 110 includes bottom plate 111 and the 4th connector being fixed on bottom plate, bottom plate 111
It is connected by screw to support ring 142;4th connector is hollow pipe fitting, including interlude 113 and setting in interlude
The bending section 114 at both ends;It is two sections that the interlude 113, which is divided to, is connect by threeway with bottom plate 111, the end of bending section 114 is set
Be equipped with internal screw thread, wherein the end of a bending section is threadedly coupled with wheel stand 25, the end of another bending section with it is hollow
Axis 15 stretches out the threaded one end connection of third end cap 20.Through-hole is offered on first cylinder 140, is connected on bottom plate 11 with the 4th
Fitting junction offers through-hole, and the conducting wire of motor 3 sequentially enters the connection of the 4th connector after being pierced by the cavity of hollow shaft
In cavity, and enter in robot body through the through-hole on bottom plate 11, the first cylinder 140 and be electrically connected between controller, realizes
Control of the controller to motor;And the through-hole on bottom plate, the first cylinder is sealed with sealant.Supporting structure is simple, matter
Amount is light, by wire arrangements in the tube, sealing, when preventing leak, while avoiding driving roller rotation conducting wire easily with shaft or
The problem of barrier outside person etc. is wound.
In the present embodiment, the bottom of first cylinder is provided with flow sensor 150, flow sensor 150 and control
It is electrically connected between device processed.When robot works in the duct, the flow velocity of water in pipeline can detecte by flow sensor, and
It is shown in host computer on the ground.It is fixedly installed on the bottom plate 111 using kickboard 160 made of light material, works as machine
Device people increases buoyancy when working in water, robot is in suspended state, and helical blade is equivalent to propeller, helical blade rotation
Draining driving pipe robot fast forwards through backward, improves working efficiency.
In the present embodiment, the shell 100 is along being divided axially into two halves.It offers on the shell 100 for set casing
The threaded hole of body and outer cylinder, it is easy to disassemble by the fixed shell of screw and outer cylinder.The inner walls are provided with multiple and outer cylinder
The locating piece matched, corresponding position offers locating groove on outer cylinder, and locating piece is inserted into locating groove by when assembly, prevents
When pipe robot works, shell relatively rotates with outer cylinder.The both ends of the shell are provided with head plate, prevent water or dirt
Object etc. enters in the gap between shell and driving device.The shell is cone shuttle shape, including three sections:Intermediate direct tube section and two
The rotary table shell section at end, three sections of integrated moldings.Shuttle shape design is bored, pipe robot is in work process, the middle part of shell and pipe
Wall contact, both ends tilt, and prevent blocking, are conducive to pipe robot and advance.
In the present embodiment, the blade 101 of the outer peripheral surface of the shell 100 is continuous helical shape.The helical blade
Screw pitch is 5cm, and the height of helical blade is 3cm, and the width of helical blade is 1cm.Pipe machine can be improved in the appropriate screw pitch that increases
Device people's forward speed;Screw pitch is excessive then small with the contact area of inner wall of the pipe, and frictional force is insufficient.The height of helical blade is too low,
Quick abrasion then needs to be replaced frequently;The height of helical blade is too big, and shell volume is big, and pipe robot entirety center of gravity is got higher, surely
Qualitative difference.The width of helical blade is too wide, then weight weight, driveability decline;Width is too wide too small, then easy to wear, and intensity
Not enough, hard object easy fracture is collided.
In the present embodiment, the top surface of the helical blade 101 is provided with anti-skid chequer, prevents skid, increases friction
Power.
Embodiment two:
In the present embodiment, driving device is divided into three sections along its length:It is rolled including driving roller and setting in driving
The Mecanum wheel at cylinder both ends;Using Mecanum wheel-helical blade roller-Mecanum wheel combination.
Eight grooves, the bottom surface of concave surface are uniformly provided on the outer peripheral surface of second connector stretching second end cover part
For plane, it is embedded a locating rack in each groove, locating rack is U-shaped, and locating rack is connected by screw to the second connector, often
A Mecanum wheel passes through both ends of the shaft rotation connection corresponding with locating rack.
Other parts are identical with embodiment.
