A kind of pylon of truss structure

Technical field

The present invention relates to a kind of pylon of horizontal axis wind-driven generator group of wind-power electricity generation.Wind power generating set can be divided into large-scale, medium-sized and small-sized wind power generator group by scale.The pylon of a kind of truss structure of the present invention belongs to large-scale and pylon that is medium wind-driven generator group.The pylon group two kinds of horizontal axis and vertical axis aerogenerator can be divided into again by the pylon of structure wind-driven generator group, the invention belongs to the pylon of horizontal axis wind-driven generator group.Be divided into again truss structure, steel tube structure and concrete structure three kinds by pylon structure, the invention belongs to the pylon of truss structure.

Background technique

Horizontal axis large medium size wind generator comprises the pylon in cabin, wind wheel, support cabin, and some pylon is equipped with one end and is connected with pylon, the drag-line that the other end is connected with drag-line basis.

The pylon of horizontal shaft wind-power unit not only will bear blast, also will bear the whole Dynamic And Static Loads in running of wind generating set process simultaneously.The structure of pylon has the forms such as steel cylinder, concrete and truss.Current big-and-middle-sized Wind turbines many employings steel cylinder pylon, the increase cylinder diameter along with Wind turbines capacity can reach several meters even tens meters, and transport very difficult, on land, some can not transport only not.In order to convenient transportation, some steel cylinder pylon needs, by tower cylinder segmentation even burst manufacture, to assemble to scene again, solve transportable problem like this, but but reduce the strength and stiffness of steel cylinder, thus add weight and cost, field erected workload is large too in addition.The pylon of truss structure has lightweight than steel cylinder pylon, many advantages such as tower shadow effect is little, so be widely used in small-sized wind power generator, but along with the increase of Wind turbines capacity, pylon up to tens meters, rice even up to a hundred, especially wind energy turbine set all will be located at the large place of wind, the life safety of the staff of climbing pylon has been arrived in these serious threats, so eliminated the pylon of truss structure at present in large-scale wind electricity unit.Owing to there is above-mentioned problem, in wind power generating set large-scale at present, have to adopt concrete pylon more and more.This pylon makes engineering work load, transport volume increase undoubtedly.

Summary of the invention

The object of this invention is to provide one can make pylon lightweight, and tower shadow effect is little, can increase the capacity of Wind turbines further, and staff especially can be avoided because of outdoor climb tower and the danger faced.In order to solve the problem, the pylon of a kind of truss structure of the present invention comprises the pylon root be connected with basis, the tower top be connected with cabin, the lowering or hoisting gear be elevated for personnel and equipment and tower body, it is characterized in that the rod member forming pylon truss structure has a kind of rod member to be thick montant, the thick montant that described lowering or hoisting gear is located at as truss member is inner, and described thick montant is formed by connecting by several sections of pipe nipples.

The pylon of a kind of truss structure as above, is characterized in that described lowering or hoisting gear is for the upper and lower cat ladder of personnel.

The pylon of a kind of truss structure as above, is characterized in that the elevator that described lowering or hoisting gear is made up of cage and guide rail.

Just useful effect can be obtained from following four aspects after adopting such structure.

1. staff is from from the inner climbing tower of the thick montant of steel tube structure, solves the safety problem of outdoor tower of climbing.

2. can alleviate the weight of pylon widely, thus reduce costs.

3. not only according to the situation of the road towards wind energy turbine set, whole pylon can be split into the pipe nipple of suitable length, and pylon pipe nipple also can be that unit splits into less part with comparalive ease with rod member, solves the problem that transport is difficult.

4. greatly can reduce tower shadow effect, be conducive to selecting leeward to wind wheel, thus save yaw system, therefore make its structure simple, cost is reduced.

Embodiment

Composition graphs 1, Fig. 2 and Fig. 3, the first mode of execution of the pylon of a kind of truss structure of the present invention, comprise the pylon root 5 be connected with basis, the tower top 1 be connected with cabin and the rod member forming truss, these rod members are divided into again thick montant 2, thin montant 3, connecting rod 4.Thick montant 2 is made up of steel cylinder, leads directly to tower top from pylon root, and certainly thick montant 2 and whole pylon all can be divided into some pipe nipples and be docking together, and the cat ladder being furnished with safety rope 7 is just located at the inside of thick montant 2 as the lowering or hoisting gear 6 that personnel pass through.Thin montant 3 also leads directly to tower top as thick montant 2 bottom pylon, it also can be made with steel cylinder, when its inner space is enough large time, also lowering or hoisting gear can be installed, haul passage and personnel channel are separated, guarantee safe production, so thin montant 3 also just becomes thick montant 2, and certainly thin montant 3 can also make of the various section bar such as angle steel, channel-section steel.

It is lightweight that the beneficial effect of this mode of execution is that its diameter group reaches the pylon of several meters even steel tube structure of tens meters, and cost is low.It is fewer than concrete pylon site operation amount, and transport volume is also little.The dangerous problem of the outdoor tower of climbing of personnel that the pylon it solving truss structure in the past exists, the advantage that the tower shadow effect that the pylon that simultaneously it maintains truss structure has is low, so he can support the use to wind wheel with leeward, there are the various advantages of leeward to wind wheel.

Composition graphs 4, the second mode of execution and the first mode of execution of the pylon of a kind of truss structure of the present invention are similar, difference is only one of them thin montant 3 to change another thick montant 8 with guide rail 10 into, and has installed the i.e. elevator of another kind of lowering or hoisting gear 9 in another thick montant 8.The advantage of the second mode of execution the passage of the passage of lifts personnel with lifting equipment can be separated, and is more conducive to safety in production.

Be quadrilateral for pylon transverse section in a first embodiment, certainly can be transformed into triangle, pentagon or other polygonal shape; Also the rod member in various direction can be increased and decreased; Thick montant 3 also can resemble the second mode of execution and be transformed into two or many; Also can at the inside lift-mounting of another thick montant 8; Also according to the situation of the road towards wind energy turbine set, whole pylon can be split into the pipe nipple of suitable length; Lower thick upper thin can also be become identical for the cross dimension of the pylon upper and lower in the first mode of execution, and can with drag-line reinforcing etc.Simply convert as above-mentioned these and also all drop among protection of the present invention.
