Description

The pin-joint mechanism that is used for the solar panels sun-following device

Technical field

The utility model refers to a kind of pin-joint mechanism that is used for the solar panels sun-following device especially relevant for a kind of pin-joint mechanism.

Background technology

General solar panels sun-following device all has pin-joint mechanism, so that the solar panels on the device can be adjusted angle at any time with over against daylight; Yet the pin-joint mechanism of general known solar panels sun-following device is to utilize to be undertaken in the ball bearing of rotor plate both sides as support.

But using ball bearing to support pin-joint mechanism but has following shortcoming: because the function of bearing is in order to bolster or parts on shaft, the running accuracy of retainer shaft reduces the friction and wear between rotating shaft and the supporting, but not is used for the load-carrying support.

So, if use ball bearing, using under the pin-joint mechanism long-time as supporting, ball bearing then damages easily, thereby must change ball bearing often keeping the usefulness of pin-joint mechanism, but has improved the use cost of pin-joint mechanism like this.

In addition, because the ball bearing of known pin-joint mechanism is to be pressed into from the rotor plate both sides, because the tolerance on the machining, these two ball bearing also can't reach best concentricity, so, stability when making the pin-joint mechanism transmission is not good, causes ball bearing to damage easily yet and improves use cost.

Therefore, how to make the not fragile concurrent best usefulness of waving of pin-jointed structure of solar panels sun-following device, promptly become the problem that this case inventor is studied.

The utility model content

In view of this, the utility model fundamental purpose is to provide a kind of pin-joint mechanism that is used for the solar panels sun-following device, has bigger contact area by between rotating shaft and the axle sleeve, not only can bear bigger pressure, and can improve transmission stability, and prolong the serviceable life of pin-joint mechanism.

In order to reach above-mentioned purpose, the utility model provides a kind of pin-joint mechanism that is used for the solar panels sun-following device, and this sun-following device comprises locating rack, turret, reaches the pin-joint mechanism that connects this locating rack and this turret; Wherein, this pin-joint mechanism comprises rotating shaft and is socketed on two axle sleeves of this rotating shaft respectively, and this rotating shaft is fixedly connected on this turret, and the corresponding configuration of these two axle sleeves and be fixedly connected on this locating rack.

As can be seen from the above technical solutions, the pin-joint mechanism that is used for the solar panels sun-following device of the present utility model has following advantage:

Support when 1, moving as pin-joint mechanism with rotating shaft, can improve general known pin-joint mechanism and utilize bearing as support at the turret two ends, and cause the not good shortcoming of durability, rotating shaft has bigger Area of bearing, can bear bigger pressure, effectively prolong the serviceable life of pin-joint mechanism.

Support when 2, moving as pin-joint mechanism with rotating shaft, can improve general known pin-joint mechanism utilizes bearing as support at the turret two ends, do not cause concentricity good and reduce the shortcoming of transmission stability, because whole locating rack and turret are traversed in rotating shaft, so when pin-joint mechanism moves, the problem that does not have concentricity can make transmission stability improve and the serviceable life of prolongation pin-joint mechanism.

Embodiment

Relevant detailed description of the present utility model and technology contents, conjunction with figs. is described as follows, however appended accompanying drawing only provides reference and explanation usefulness, is not to be used for the utility model is limited.

Please refer to Fig. 1 to shown in Figure 3, be respectively three-dimensional exploded view of the present utility model, combination of side view and along the sectional view of the 4-4 line of Fig. 2, the utility model provides a kind of pin-joint mechanism that is used for the solar panels sun-following device, and this sun-following device comprises locating rack 10, turret 20 and pin-joint mechanism 30.

One side of locating rack 10 is provided with perforation 11, and its opposite side has the arm of being located by connecting 12; Turret 20 is provided with the through hole 21 with the 11 mutual corresponding configurations of boring a hole, and a side of turret 20 has the arm of being rotationally connected 22; The arm 12 that is located by connecting interconnects with expansion link (figure does not express) with the arm 22 that is rotationally connected.

Pin-joint mechanism 30 interconnects with locating rack 10 and turret 20, pin-joint mechanism 30 comprises rotating shaft 31, two axle sleeves 32 and two pads 33, rotating shaft 31 is a solid shaft, rotating shaft 31 is arranged in perforation 11 and through hole 21 to articulate locating rack 10 and turret 20, two axle sleeve correspondences dispose and are fixedly connected on this locating rack 10, be in detail axle sleeve 32 be arranged in respectively the perforation 11 both sides and with rotating shaft 31 mutual sockets, pad 33 is socketed on rotating shaft 31 respectively and amplexiforms packing mutually with axle sleeve 32; Rotating shaft 31 both sides are respectively equipped with groove 311 and fix spacing with two or more fixed heads 40.

Rotating shaft 31 is mutually permanently connected with turret 20; Turret 20 is that axle center relative positioning frame 10 rotates with rotating shaft 31.When turret 20 rotated with the adjustment angle, rotating shaft 31 was rotated synchronously with turret 20.

Please refer to Fig. 4 and shown in Figure 5, be respectively solar panels sun-following device stereographic map of the present utility model and side view, the arm 22 that is rotationally connected is connected with expansion link 50 with the arm 12 that is located by connecting.

Further specify, expansion link 50 has canned paragraph 51 and is arranged in mobile section 52 of canned paragraph 51 inside, be rotationally connected arm 22 with move section 52 and fixedly connected, 12 on the arm of being located by connecting is fixedlyed connected with canned paragraph 51; Expansion link 50 can be atmospheric pressure pole or oil compression rod, and its bottom is connected with controller 60, elongates or shortens in order to control expansion link 50.

The top of turret 20 also is connected with back shaft 70, and back shaft 70 interfixes with U type clasp 23 with turret 20; And back shaft 70 is fixedlyed connected with solar panels (figure does not express); The bottom of locating rack 10 and base 80 and controller 90 are mutually permanently connected.
