Specific embodiment
In order to enable those skilled in the art to better understand the solution of the present invention, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.
Referring to FIG. 2, Fig. 2 is a kind of inspection system of wind generator set blade lightning-protection system disclosed by the embodiments of the present invention
The structural schematic diagram of system.
As shown, in a specific embodiment, wind generator set blade lightning-protection system provided by the present invention
Inspection system, be mainly made of suction type robot 101, camera 103, resistance test instrument 13, controller 12 etc..
Suction type robot 101 connects device to sudden strain of a muscle for moving on the blade 15 of wind power generating set from root terminad
1 position detected is equipped with negative-pressure vacuum adsorption element, to be absorbed and fixed on blade 15 in climbing or traveling.Example
Such as, this robot can be equipped with left leg and right leg (quantity can be one or more), and under left leg and right leg and blade contact
The sucker that can be vacuumized is installed at end respectively, and walking can be climbed in the tower of generating set and blade 15.When stepping left leg
After contacting with blade 15, sucker starts to vacuumize, and is firmly adsorbed on blade 15, then steps right leg and blade contact, inhales
Disk starts to vacuumize, and is firmly adsorbed on blade 15, and then, the sucker of left leg is communicated with the atmosphere, and lays down adsorption capacity, thus after
It is continuous to stride forward, so alternately, the purpose climbed or advanced on blade 15 can be realized.Since the other parts of robot are adopted
It can be realized with existing robot technology, therefore, just not reinflated description here.
Certainly, other than suction type robot, mobile unit can also be other kinds of robot or can be in leaf
The intelligent controlling device climbed, advanced on piece 15.For example, can be the two rows of elastic conducting wheels of Robot Design or so as travel section
Part, two rows of elasticity guide wheels are in the same plane, are located at the left and right sides of 15 thickness direction of blade, blade 15 is clamped in
Centre, when guide wheel rotation, robot can advance on blade 15, as 15 thickness of blade gradually becomes from root terminad
Narrow, under the effect of elasticity, the spacing of two side guide wheels also becomes narrow gradually, to be able to maintain on blade 15 always, equally can
Realize the purpose climbed or advanced on blade 15.
It is the partial enlarged view of mobile unit shown in Fig. 2 please also refer to Fig. 3, Fig. 3.
As shown, camera 103 is high-definition camera, the image of high definition can be transmitted, is set to suction type robot 101
On, with the freedom degree of regulatable vision angle in suction type robot 101.Specifically, camera 103 passes through first mechanical arm
102 are installed on suction type robot 101, and first mechanical arm 102 is three stage structure, and there are two nodes for tool, can freely move
Dynamic rotation, so that camera 103 can be shot from any angle.
Resistance test instrument 13 is equipped with the first detection probe and the second detection probe (being metal probe), and the first detection is visited
Head is mounted in suction type robot 101, is connect by the first conducting wire 105 with resistance test instrument 13, is had relative to blade 15
There is the freedom degree of vertical movement, the second detection probe (is embedded in leaf by the downlead 2 that the second conducting wire 106 connects lightning-protection system
In piece).
Specifically, the first detection probe is installed on suction type robot 101, second mechanical arm by second mechanical arm 104
104 can move up and down, to drive the first detection probe to move perpendicular to blade 15.
The main function of first detection probe and the second detection probe is that sudden strain of a muscle connects device 1 and lightning protection downlead 2 is for detecting
No intact, the end of two probes is equipped with threading hole, and the first conducting wire 105 and the second conducting wire 106 can be directly anchored to threading hole
Interior, resistance test instrument 13 is provided with straight cutting empty slot, and the first conducting wire 105 and the second conducting wire 106 are inserted directly into and both can be used.
Controller 12 is equipped with control flow, to negative pressure for remotely controlling suction type robot 101 and camera 103
Formula robot 101 and camera 103 are operated, and show the image that camera 103 returns, due to using general controls technology
It can be realized, here just not reinflated description.
When needing to detect, the suction type robot 101 connected is released from the window 14 at 11 top of cabin, passes through control
The remote control of device 12 processed, the first conducting wire 105 is voluntarily climbed and is reached where 15 top of blade dodges and connect device 1 in tow for suction type robot 101
Region then moved vertically using second mechanical arm 104 contact so that the first detection probe and sudden strain of a muscle connect device 1 and (can be used and take the photograph
As whether first 103 inspection reality touches)；Then, staff is tested in cabin 11 using resistance test instrument 13,
Side is connected to 2 bearing of lightning protection downlead at blade root by the second conducting wire 106 and the second detection probe, and the other side passes through the
One conducting wire 105 and the second detection probe are connected to sudden strain of a muscle and connect device 1, check whether the result that resistance test instrument 13 is measured is allowing model
In enclosing, that is, it can determine whether lightning-protection system is in normal condition.
If not using metal probe, only check that sudden strain of a muscle connects whether device 1 appearance is intact to judge lightning-protection system by operator control panel
Whether normal condition is in.
Referring to FIG. 4, Fig. 4 is the inspection of another wind generator set blade lightning-protection system disclosed by the embodiments of the present invention
The structural schematic diagram of system.
In another embodiment, other than the safeguard procedures of personnel, mobile unit safeguard procedures are additionally provided.
Exist as suction type robot 101 as power loss or is slid as caused by the influence of other particular surroundings, because
This needs to carry out protection.As shown in figure 4, one end of protection rope 202 is fixed on suction type machine by the first fixed point 201
The other end component of the tail portion of device people 101, protection rope 202 is fixed on by the second fixed point 203 in 11 outside of cabin.When negative
When pressure type robot 101 slides due to various reasons, the not Crater face of suction type robot 101 can be protected, injures equipment by a crashing object
Or the personnel of tower bottom.
What needs to be explained here is that protection rope 202 and the first conducting wire 105 can merge use, a kind of reinforced belt is used
The cable of outer protection allows the first conducting wire 105 to bear to slide brought impact force due to suction type robot 101, together
Sample can be realized protection purpose.
As described above, operator is in the engine room inside of Wind turbines in entire detection process, so as to avoid
Personnel go out the risk of cabin operation, thus without employing large-scale crane equipment, or allow spider-man in machine extravehicular work, can be with
A large amount of save the costs, and field operation risk is reduced, so that blade tip lightning-protection system is fast and accurately detected.
Above-described embodiment is only preferred embodiment of the invention, is specifically not limited thereto, on this basis can be according to reality
It needs to make to have and targetedly adjust, to obtain different embodiments.For example, the lightning protection detection unit can be electricity
Bridge test equipment or microhmmeter test equipment；Alternatively, the robot of the machine artificially wired control and power supply, to enhance machine
Cruising ability (remote robot is power using internal cell, has line traffic control robot can be with external power supply) of people etc..
Since mode in the cards is more, just no longer illustrate one by one here.
