The inventor of the application researches and discovers that the wind generating set is easy to have emergency, and generally comprises parts such as an impeller or a generator, and a tower barrel is used as a basic support of the whole wind generating set, so that the structure is very firm, and the risk rate is very low. The common design of the wind turbine tower is a cone, the diameters of different heights are different, and the wind turbine tower has the characteristic of small top and large bottom, so that personnel can be separated from the cabin environment by utilizing the cone degree of the tower.
The application provides an escape device and wind generating set aims at solving prior art technical problem as above.
The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments.
The embodiment of the application provides an escape device 1, and the structural schematic diagram of the escape device 1 is shown in fig. 1 and fig. 2, and the escape device 1 comprises: a platform ring sleeve 100 and an escape platform 200;
the platform ring sleeve 100 is used for being sleeved outside the tower barrel 2 of the wind generating set, and the inner diameter of the platform ring sleeve 100 is matched with the outer diameter of the tower barrel 2 at a first designated height;
the escape platform 200 is connected with the platform loop 100.
Because the connecting part of the tower barrel 2 and the cabin 3 is generally positioned in the middle of the cabin 3 or closer to an operation area such as an impeller and a generator, and the escape device 1 is sleeved on the tower barrel 2, the coverage range of the escape device 1 is relatively large and is striking, so that a worker can easily recognize an escape destination in time and quickly determine the escape direction at the critical moment, and the time for judging when the worker in the cabin 3 escapes is reduced; secondly, the escape device 1 is closer to the operation area, so that the escape distance is shortened, and the escape time of workers in the cabin 3 can be greatly reduced.
Referring to fig. 2 again, when the escape device 1 is not in use, the escape device can be detachably connected to the bottom of the cabin 3 of the wind generating set, so that normal operation in the cabin 3 is not affected, the escape device 1 is separated from the cabin 3 in case of emergency, the escape device 1 falls due to self weight, the escape device 1 is unfolded quickly, and the delay influence on the escape time is greatly reduced; of course, the escape device 1 can also be directly clipped at the first specified height of the tower 2.
The first designated height is a first suitable position on the tower 2, the first suitable position has a sufficient safety distance with at least the nacelle 3, and the ground clearance of the first suitable position is the first designated height.
The inner diameter of the platform ring sleeve 100 of the escape device 1 is matched with the outer diameter of the tower barrel 2 at the first designated height, so that the platform ring sleeve 100 can be clamped and stopped at the first designated height of the tower barrel 2, and the escape platform 200 of the escape device 1 forms a temporary escape area with a safe distance from the cabin 3, thereby reducing risks and providing sufficient buffer conditions for later rescue or secondary escape.
The inventor of the present application considers that, in the above scheme, the clamping load of the escape device 1 on the tower 2 is borne by the platform ring 100, and if the impact force when the escape device 1 falls is too large or the load on the escape platform 200 is too large, the platform ring 100 is damaged, and the safety of the whole escape device 1 is affected. For this reason, the present application provides one possible implementation manner for the escape device 1 as follows:
referring again to fig. 1, the escape apparatus 1 further includes: the platform protection component 300, the platform protection component 300 is respectively connected with the escape platform 200 and the tower 2 to support the escape platform 200.
The platform protection component 300 can apply a certain force to the escape platform 200 by lifting or supporting to share the load on the platform loop 100 in the escape device 1, so as to protect the platform loop 100, further improve the safety of the whole escape device 1, and provide better safety guarantee for the escaper.
Alternatively, the platform protection assembly 300 may be a guy cable or a stay or the like connected to the tower 2 at a set height.
The inventor of the present application considers that if the platform protection component 300 is fixed on the tower 2 in advance, interference may be caused to the falling of the platform ring sleeve 100 and the escape platform 200 of the escape device 1, which may affect the smooth release of the escape device 1; secondly, the matching with the platform ring sleeve 100 which is clamped at the first designated height is difficult, and the load of the platform ring sleeve 100 cannot be shared if the matching is not proper, namely, the protection effect cannot be realized. To this end, the present application provides one possible implementation for the platform protection assembly 300 as follows:
referring again to fig. 1, the platform protection assembly 300 includes: a guarding ring 310 and a support 320;
the protective ring sleeve 310 is used for being sleeved outside the tower barrel 2 of the wind generating set, and the inner diameter of the protective ring sleeve 310 is matched with the outer diameter of the tower barrel 2 at a second designated height;
the supporting member 320 is connected to the guarding ring case 310 and the escape platform 200, respectively.
The platform protection component 300 adopts a structure of a protection ring sleeve 310, and can also realize the sleeve positioning with the tower barrel 2, so that the platform protection component 300 and the escape platform 200 can fall synchronously, and the interference is avoided; moreover, the distance between the protection ring sleeve 310 of the platform protection component 300 and the sleeve position of the escape platform 200 on the tower 2 is more stable, and the support 320 is more easily matched with the distance between the protection ring sleeve 310 and the escape platform 200, so as to ensure that the load of the platform ring sleeve 100 can be effectively shared.
The second designated height is a second suitable position on the tower 2 corresponding to the first designated height, the second suitable position enables the supporting member 320 to match the distance between the guarding ring sleeve 310 and the escape platform 200, and the height from the ground of the second suitable position is the second designated height.
Alternatively, the protection ring cover 310 may be located above the escape platform 200, i.e., the second designated height is higher than the first designated height, and the support member 320 connects the protection ring cover 310 and the escape platform 200 in a lifting manner, wherein the support member 320 may be a flexible connection member or a rigid connection member.
Alternatively, the guarding ring 310 may be located below the escape platform 200, i.e. the second designated height is lower than the first designated height, and the supporting member 320 is connected with the guarding ring 310 and the escape platform 200 in a supporting manner, wherein the supporting member 320 may be a rigid connecting member.
The inventor of the present application considers that, in case of an emergency, the first time the escaper transfers to the escape platform 200 is only the first step of escape, and then the escaper needs to passively wait for rescue or actively evacuate from the escape platform 200 to the ground to finally complete escape. The rescue has the limitation of untimely response and is indispensable for active secondary escape, so the escape device 1 needs to be provided with some designs matched with the active secondary escape. Therefore, the present application provides the following possible implementation manner for the escape platform 200:
referring again to fig. 1, the escape platform 200 includes: an escape platform body 210 and a movable cover plate 220;
the escape platform body 210 is connected with the platform ring sleeve 100, and the escape platform body 210 is provided with an escape hole 210 a;
the movable cover 220 is movably connected to the escape platform body 210 at the escape hole 210 a.
The escape hole 210a is constructed to facilitate evacuation of the evacuee from the escape platform 200 to the ground with the aid of other active escape devices such as a parachute, a rope, etc. When active secondary escape is not required, the escape hole 210a can be sealed by the movable cover 220, so that the escape platform body 210 is a complete escape area, and is convenient for an escaper to use temporarily. The movable cover 220 is movably connected with the escape platform body 210, such as hinged connection, sliding connection or separable connection, so that the escape platform is convenient to open, the escape time is saved, and the safety of personnel is guaranteed to the maximum extent.
The inventor of the application considers that the escape device 1 requires the escape platform 200 to have a larger area and to have more people and safer people when in use; when the escape device 1 is not in use, the smaller the area of the escape platform 200, the better the escape platform is, and the escape platform is convenient to place. Therefore, the present application provides the following possible implementation manner for the escape platform 200:
the escape platform body 210 comprises a platform main body and an expansion platform;
the platform body is connected with a platform ring sleeve 100;
the expansion platform is movably connected with the platform main body.
The escape platform 200 is designed into an area variable structure comprising a platform main body and an expansion platform, and when the escape device 1 is in a non-use state, the expansion platform is folded to reduce the volume of the escape platform 200, so that the escape platform is convenient to place; when the escape device 1 is in a use state, the expansion platform is expanded to enlarge the usable area of the escape platform 200, so that the carrying capacity is increased, and escapers evacuated to the escape platform 200 are safer.
The expansion platform is movably connected with the platform main body, and can be hinged, connected in a sliding mode or connected in a splicing mode, so that the folding and unfolding operation of the escape platform 200 is simplified, and the escape time is saved.
Optionally, a railing may be disposed at the outer edge of the expansion platform to prevent the escaper from falling off the escape platform 200.
The inventors of the present application consider that in order to facilitate the ability of an evacuee to actively evacuate from the escape platform 200 to the ground, an active escape apparatus may be added to the present escape apparatus 1. For this reason, the present application provides one possible implementation manner for the escape device 1 as follows:
the escape apparatus 1 further comprises: a secondary escape device;
the secondary escape device is arranged on the escape platform body 210 or connected with the protection ring sleeve 310.
Optionally, the secondary escape device can be a parachute, a high-rise escape device or the like, and the secondary escape device is placed on the escape platform body 210 or connected with the protection ring sleeve 310 or the like, so that the place for the escaper to take can be conveniently used for active secondary escape.
The inventor of the application considers that the escape device 1 is clamped at the first designated height of the tower barrel 2, an escaper is very close to the outer wall of the tower barrel 2, the outer wall of the tower barrel 2 is conical, and when the escaper carries out active secondary escape, the outer wall of the tower barrel 2 can be fully utilized. Therefore, the application provides the following possible implementation mode for the secondary escape device:
the secondary escape device comprises: an escape device;
referring again to fig. 1, the escape apparatus includes a hook 410, a harness (not shown) and a rope 420; the hook 410 is connected with the protection ring sleeve 310, the hanging strip is arranged on the escape platform body 210 for fixing the escaper, and the rope 420 is used for connecting the hook 410 and the hanging strip.
When the person actively escapes for the second time, the person wears the hanging belt, locks the hanging belt with the rope 420 hung on the hook 410, withdraws the escape platform 200 from the escape hole 210a on the escape platform body 210, and gradually descends to the ground by releasing the rope 420 with the help of the support of the outer wall of the conical tower tube 2.
Optionally, the secondary escape device 1 may further include a slow-descending device (not shown in the figure), which may be disposed at the hook 410 or at the sling, for controlling the releasing speed of the rope 420 to ensure the safety of the escaper.
The position where the hook 410 of the escape apparatus is connected with the protection ring case 310 corresponds to the escape hole 210a of the escape platform body 210, so that the escaper can evacuate from the escape hole 210a and the rope 420 can be smoothly released.
Based on the same inventive concept, the embodiment of the present application provides a wind turbine generator system, and the structural schematic diagram of the wind turbine generator system is shown in fig. 3 and fig. 4, and the wind turbine generator system includes a tower 2, and further includes: a cabin 3 and the escape apparatus 1 of the first aspect;
the escape device 1 is sleeved on the tower barrel 2 and is separably connected to the bottom of the cabin 3.
The escape device 1 is detachably connected to the bottom of the cabin 3 when not in use, and normal operation in the cabin 3 is not affected. When an emergency occurs, the escape device 1 is separated from the cabin 3, the escape device 1 falls down due to self weight, the escape device 1 is unfolded quickly, and the delay influence on the escape time is greatly reduced.
The inventor of the present application considers that the escape apparatus 1 is detachably connected to the floor 3a of the cabin 3, and it is necessary to ensure reliability when the two are connected and smooth and free when the two are separated. To this end, the present application provides the nacelle 3 with one possible implementation:
referring again to fig. 3, the bilge 3a of the nacelle 3 includes: a fixed bilge 3a1 and a movable bilge 3a 2;
the fixed bilge 3a1 at least has a hollow part matched with the escape device 1;
the movable bilge 3a2 is movably connected with the fixed bilge 3a1, and the movable bilge 3a2 can at least partially cover the hollow part;
the escape device 1 is arranged on the movable bilge 3a2 and corresponds to the hollow part.
The hollow-out part of the fixed bilge 3a1 matched with the escape device 1 provides a passing space for the release of the escape device 1. The movable connection between the movable bilge 3a2 and the fixed bilge 3a1 can adopt locking structures such as a mechanical lock or an electromagnetic lock, and when the escape device 1 is in a non-use state, the movable bilge 3a2 plays a role in supporting and fixing the escape device 1, so that sufficient reliability is ensured; when the escape device 1 is in a use state, the movable bilge 3a2 moves relatively to the fixed bilge 3a1 by unlocking a mechanical lock or an electromagnetic lock, so as to leave a hollow space of the fixed bilge 3a1, and the escape device 1 falls freely under the influence of gravity after losing the supporting force of the movable bilge 3a2, thereby completing a releasing action.
Based on the above consideration, the inventor of the present application provides the following possible implementation manner for the nacelle 3:
referring to fig. 4 again, the cabin bottom of the cabin 3 has a hollow portion matching with the escape device 1, and the escape device 1 is disposed at the hollow portion and detachably connected to the cabin bottom 3a of the cabin 3.
The escape device 1 and the cabin bottom 3a of the cabin 3 can be connected by a locking structure such as a mechanical lock or an electromagnetic lock. When the escape device 1 is in a non-use state, the escape device 1 becomes a part of the cabin bottom 3a of the cabin 3 for normal operation of workers; when the escape device 1 is in a use state, the escape device 1 loses the connecting force of the locking structure and then falls freely under the influence of gravity by unlocking the mechanical lock or the electromagnetic lock, and the releasing action is completed.
By applying the embodiment of the application, at least the following beneficial effects can be realized:
1. because the connecting part of the tower barrel 2 and the cabin 3 is generally positioned in the middle of the cabin 3 or closer to an operation area such as an impeller and a generator, and the escape device 1 is sleeved on the tower barrel 2, the coverage range of the escape device 1 is relatively large and is striking, so that a worker can easily recognize an escape destination in time and quickly determine the escape direction at the critical moment, and the time for judging when the worker in the cabin 3 escapes is reduced; secondly, the escape device 1 is closer to the operation area, so that the escape distance is shortened, and the escape time of workers in the cabin 3 can be greatly reduced;
2. the cabin bottom 3a can be connected with the cabin 3 in a separable way at ordinary times, and the normal operation in the cabin 3 is not influenced;
3. when in emergency, the escape device 1 is separated from the engine room 3 and falls down due to self weight, so that the escape device can be unfolded quickly, and the delay influence on the escape time is greatly reduced;
4. the platform ring sleeve 100 of the escape device 1 is clamped and stopped at a first designated height of the tower 2, and the escape platform 200 of the escape device 1 forms a temporary escape area with a safe distance from the cabin 3, so that the risk is reduced, and sufficient buffer conditions are provided for later rescue or secondary escape;
5. the platform protection component 300 adds safety guarantee to the escape device 1.
