Embodiment
Embodiment in is by reference to the accompanying drawings further described by the present invention below:
As shown in Fig. 1 ~ 4, the present invention mainly comprises full-automatic sun tracker 1, position angle over travel Machine guarding 2 and angle of pitch integral bidirectional Machine guarding 3, and the casing of full-automatic sun tracker 1 is provided with position angle over travel Machine guarding 2.
As shown in Figure 2; described position angle over travel Machine guarding 2 comprises bearing seat 5; main shaft 6 is connected by bearing 8 in bearing seat 5; main shaft 6 is set with over travel pivoted housing 7; main shaft 6 freely can turn round in over travel pivoted housing 7; be provided with stroke-limit chamber 9 in over travel pivoted housing 7, main shaft 6 is provided with positive stop key 10, is limited the scope of main shaft 6 rotational angle in stroke-limit chamber 9 by positive stop key 10.By screw fixing horizontal protection block 11 on bearing seat 5, over travel pivoted housing 7 outside surface is provided with limiting plate 16, and when over travel pivoted housing 7 turns to certain angle, limiting plate 16 stops operating by the stop of level protection block 11.
When positive stop key is assemblied on main shaft; over travel pivoted housing will be defined around the scope of main axis; therefore when bearing seat is in the process of main axis; the level protection block be fixed on bearing seat will touch over travel pivoted housing; if be rotated further; then rotation is collided positive stop key by over travel pivoted housing, thus realizes mechanical position limitation protection.
Stroke-limit chamber angular range will set according to needs, as long as the shock Mechanical Structure Strength meeting positive stop key and the remaining part of the corresponding circumference in stroke-limit chamber of over travel pivoted housing in theory enough.Positive stop key design is when the centre position in stroke-limit chamber; by the scope in appropriate design over travel pivoted housing upper limit stroke chamber; the bearing seat scope of rotating forward can be realized and be greater than 360 °; the scope that simultaneously rotates backward is greater than 90 °; namely realize full-automatic sun tracker position angle slewing area forward and be greater than 360 °, be oppositely greater than the mechanical position limitation design protection of 90 °.Also positive stop key can be designed at any one edge in stroke-limit chamber, for the rotational orientation angular region in simple one of them direction of increase.
Under the angular range in stroke-limit chamber is greater than 180 ° of situations, over travel pivoted housing well can not coincide and to rotate on main shaft, therefore, as shown in Figure 4, main shaft 6 is along the circumferential direction provided with guide groove 17, bottom over travel pivoted housing 7, be provided with orienting lug 18, orienting lug 18 is slidably mounted in guide groove 17.When over travel pivoted housing 7 is around main axis, orienting lug 18 coordinates guide groove 17 to play stable guide effect.Obviously, with upper type just wherein one preferably design proposal, to meet the better identical of over travel pivoted housing and main shaft.Such as stroke-limit chamber 9 is designed to non-permeable structures, makes on sustained height, be designed to cavity with positive stop key 10 and all the other height be designed to not empty the method for designing of structure, and general designer's other method for designing all thinkable all can realize both better coincideing.
The sun tracker box side 4 of full-automatic sun tracker 1 is provided with angle of pitch integral bidirectional Machine guarding 3; as shown in Figure 3; angle of pitch integral bidirectional Machine guarding 3 comprise be arranged on full-automatic sun tracker 1 declination axis 15 on and the pitching protection block 12 rotated with declination axis 15, pitching protection block 12 place is circumferentially provided with the first Anti-rotary block 13 and the second Anti-rotary block 14 of restriction pitching protection block 12 slewing area.
When the shading bar of full-automatic sun tracker is in surface level, pitching protection block is in position between the first Anti-rotary block and the second Anti-rotary block, and pitching protection block is the smaller angle designed with the angular distance of the first Anti-rotary block and the close side of the second Anti-rotary block respectively, the angular distance of rotating towards opposite side is the larger angle designed, the rotation of the full-automatic sun tracker angle of pitch at one section of angular range will be formed like this, size and the position of block and the first Anti-rotary block and the second Anti-rotary block is protected by appropriate design pitching, the declination axis scope of rotating forward can be realized and be greater than 90 °, the scope that simultaneously rotates backward reaches 10 °, namely realize full-automatic sun tracker angle of pitch slewing area forward and be greater than 90 °, oppositely reach the integral bidirectional mechanical position limitation design protection of 10 °.Described integral bidirectional, is embodied in and namely can realizes by only pitching protection block the mechanical position limitation protection that rotates forward and rotate backward in both direction.The described two-way method for designing being also embodied in employing first Anti-rotary block and the second Anti-rotary block; even if the mechanical position limitation rotating forward and rotate backward in both direction is protected to adopt an Anti-rotary block also can meet; but adopt two Anti-rotary blocks to double making the ability of protection, reliability is higher.
Three of Fig. 5 ~ 7 are illustrated as three exemplary position schematic diagram of angle of pitch integral bidirectional Machine guarding, are respectively full-automatic sun the tracker state of (namely shading bar is horizontal), full-automatic sun tracker angle of pitch under reset position from left to right and move downward the location status of (namely shading bar moves downward) to-10 ° and the full-automatic sun tracker angle of pitch moves upward (namely shading bar moves upward) to the positions of 100 °.When the fault that full-automatic sun tracker control system hardware or software cause; machine driven system is enable to reach the position of diagram latter two; the spacing stuck of machinery will be realized; this stuck mechanical impact sound that will send interruption on microcosmic, macroscopically continue; control system is carried out to the design of hardware or software in addition; automatic alarm can be realized, the design of the self-inspection that automatically resets etc., thus protect whole full-automatic sun tracker and all radiometers on it, realize the prevention of zero infringement.
By the scope in appropriate design over travel pivoted housing upper limit stroke chamber; position angle of the present invention over travel Machine guarding can realize the bearing seat scope of rotating forward and be greater than 360 °; the scope that simultaneously rotates backward is greater than 90 °; namely realize full-automatic sun tracker position angle slewing area forward and be greater than 360 °, be oppositely greater than the mechanical position limitation design protection of 90 °.Size and the position of block and two pieces of Anti-rotary blocks is protected by appropriate design pitching; the declination axis scope of rotating forward can be realized and be greater than 90 °; the scope that simultaneously rotates backward reaches 10 °; namely realize full-automatic sun tracker angle of pitch slewing area forward and be greater than 90 °, oppositely reach the integral bidirectional mechanical position limitation design protection of 10 °.
The present invention be a kind of control system can be prevented to lose efficacy cause transmission out of control mechanical protection device, better protect radiation sensor, improve the advantage such as reliability, reduce engine electrification of total system.The invention provides the full-automatic sun tracker of the motion state under the global different longitude and latitude of adaptation, its position angle exceeds 360 °, and the angle of pitch exceeds the slewing area of 90 °.Mechanical position limitation protective device structure is simple, physical strength enough, meets the designing requirement of low cost, high reliability.
