[0027] like Figure 1 The embodiment shown is an integrated embodiment, the main support beam 2 is fixed on the frame 1 of the belt conveyor. In this embodiment, the deviation correction roller unit 3, the push rod unit 5, and the power generation unit 6 share the main support beam 2 as their respective installation bases, wherein:

[0028] The deviation correction roller unit 3 is located above the main support beam 2, and the push rod unit 5 and the power generation unit 6 are respectively located at the front side and the rear side of the main support beam 2. With this integrated structural layout, the overall volume of the device can be relatively small.

[0029] Depend on Figure 1 It can be seen that the deviation correction switch unit 4 is placed on the same side as the push rod unit 5 , that is, also located on the front side of the main support beam 2 .

[0030] The middle part of the roller frame 31 of the deviation correction roller unit 3 is rotatably connected to the middle part of the main support beam 2 through a rotating assembly (not shown in the figure); a toggle arm 7 is fixedly connected to the middle part of the roller frame 31, and the top end of the toggle arm 7 is hinged to the top of the telescopic rod of the electric push rod 51 of the push rod unit 5, and the bottom end of the cylinder body of the electric push rod 51 is hinged to the articulated ear seat 52, and the articulated ear seat 52 is fixedly connected to the left end part of the front side of the main support beam 2.

[0036] In comparison, the integrated type occupies less space than the split type, and the split type is more convenient for upgrading the existing deviation correcting roller unit 3 to a passive one.

[0037] The utility model also improves the roller group of the deviation correction roller unit 3, and the roller group consists of a middle roller 33 and side rollers 32 on both sides, wherein the outer ends of the side rollers 32 are provided with tapered sections 321, and the diameter of the tapered section 321 gradually decreases from the outer end to the inner end adjacent to the middle roller along the axis, thereby further improving the deviation correction effect on the conveyor belt.

[0038] In the integrated type and the split type, the structure of the power generation unit 6 and the connection structure between the power generation unit and the main or auxiliary support beam are basically the same, and the split type embodiment is used as an example to illustrate as follows:

[0040] The power generation unit 6 is also provided with a dynamic pitch adjustment mechanism, and the dynamic adjustment enables the friction wheel 622 of the power generation assembly to maintain effective contact with the conveyor belt.

[0041] Specifically, the dynamic pitch adjustment mechanism includes: two groups of fixing components 63 fixed on the support beam 2a and respectively located on the left and right sides of the base plate 61, the base plate 61 and the fixing components 63 on both sides are hinged through a hinge shaft 67, and the base plate 61 can achieve pitch flipping around the hinge shaft 67; an elastic tensioning component 64 is also provided between the base plate 61 and the support beam, and the elastic tensioning component provides the base plate 61 with elastic force to flip upward around the hinge shaft 67, so that the friction wheel 622 of the power generation assembly fixed on the base plate 61 maintains effective contact with the conveyor belt.

[0042] Further, to prevent the bottom plate 61 from flipping downward excessively around the hinge axis 67, a limit plate 69 is also installed on the bottom plate 61. The limit plate 69 is placed below the hinge axis 67 and its top end can abut against the support beam, thereby achieving the limit. Preferably, the limit plate 69 is provided with an adjustment long hole 691. Two spaced fastening bolts 692 are passed through the adjustment long hole 691. Through the cooperation with the adjustment long hole 691, the two spaced fastening bolts 692 can not only fix the limit plate 69 to the bottom plate 61, but also prevent the limit plate 69 from flipping, and can also adjust the lower limit value of the pitching and flipping range of the bottom plate 61, that is, the lowest point of the angular stroke of flipping downward around the hinge axis.

[0043] Further, this embodiment provides an embodiment of a fixing component, which can realize the adjustment and locking of the height of the hinge axis.

[0044] Specifically, the fixing component 63 on each side includes a fixing vertical plate 631 and a Z-shaped connecting plate 632. The fixing vertical plate 631 is fixed on the support beam.

The fixing vertical plate 631 is provided with at least one adjustment long hole 6311 extending longitudinally. One bent part of the Z-shaped connecting plate 632 abuts against the corresponding side part 611 of the bottom plate 61 and passes through the corresponding end of the support hinge axis 67.

[0045] Further, a height locking bolt-nut pair 633 is also fixedly connected between the middle part of the Z-shaped connecting plate 632 and the support beam. The height locking bolt-nut pair 633 cooperates to adjust the height of the fixing vertical plate 631 and lock the Z-shaped connecting plate 632, and shares and strengthens the load-bearing capacity.

[0046] Preferably, in this embodiment, two mutually parallel adjustment long holes 6311 are opened so as to select a suitable one for installation according to needs, thereby realizing the distance between the hinge axis 67 and the support beam in the horizontal direction.

[0047] This embodiment provides an embodiment of an elastic tensioning component. Refer to Figure 5 As shown, it includes a guide rod 642. The front end of the guide rod 642 is screwed and fixed to the front fixing plate 641. The front fixing plate 641 is fixed to the bottom plate 61.
