The utility model provides a ferrying device 100 for a photovoltaic cleaning system.

Referring to fig. 1 and 2, in an embodiment of the present utility model, the ferry device 100 for a photovoltaic cleaning system includes a guide rail 10, a ferry vehicle 30, and a locking mechanism 50; the ferry vehicle 30 is slidably connected with the guide rail 10, and the ferry vehicle 30 can move along the extending direction of the guide rail 10; the locking mechanism 50 is installed on the ferry vehicle 30, the locking mechanism 50 is used for locking the ferry vehicle 30 and the guide rail 10, specifically, the locking mechanism 50 comprises a clamping piece 51 and a driving piece 53, the clamping piece 51 is used for clamping the guide rail 10, and the driving piece 53 is connected with the clamping piece 51 to drive the clamping piece 51 to hug tightly or separate from the guide rail 10.

According to the technical scheme, the locking mechanism 50 is arranged on the ferry vehicle 30, so that the technical problem that the ferry vehicle 30 cannot be stably positioned on the guide rail 10 is solved. In the operation process, when the ferry vehicle 30 needs to move along the guide rail 10, the clamping piece 51 releases the guide rail 10 so that the ferry vehicle 30 can smoothly move; when the ferry vehicle 30 needs to be temporarily stopped at a specific position of the guide rail 10, the clamping piece 51 is tightly held with the guide rail 10 so as to lock the ferry vehicle 30 and the guide rail 10, thereby avoiding the situation that the ferry vehicle 30 continues to move on the guide rail 10 or the ferry vehicle 30 is overturned.

When the ferry vehicle 30 needs to be locked with the guide rail 10, the driving piece 53 drives the clamping piece 51 to hug tightly with the guide rail 10, and the clamping block 513 extends into the corresponding lock hole 111, so that the ferry vehicle 30 is reliably locked, and the situation that the ferry vehicle 30 slides due to insufficient hugging force between the clamping piece 51 and the guide rail 10 is avoided; when the ferry vehicle 30 needs to move along the guide rail 10, the driving member 53 drives the clamping member 51 to separate from the guide rail 10, and the clamping block 513 leaves the locking hole 111, so that the ferry vehicle 30 slides smoothly.

Further, the clamping member 51 is elastically connected to the clamping block 513 by an elastic member 515, the elastic member 515 may stretch toward or away from the guide rail 10, and the clamping block 513 may move toward or away from the locking hole 111 relative to the clamping member 51. In the process that the driving member 53 drives the clamping block 513 to extend into the lock hole 111, the elastic member 515 may provide appropriate buffering, so that on one hand, the clamping block 513 is prevented from extending too deeply into the lock hole 111 to cause pressure loss of the clamping block 513 itself or the guide rail 10, and on the other hand, the condition that the clamping block 513 extends too shallow into the lock hole 111 or the extending position is offset to cause poor locking state is avoided.

In the embodiment of the present utility model, the clamping member 51 includes two oppositely disposed clamping blocks 511, and the two clamping blocks 511 are moved toward each other to be held tightly against the guide rail 10 or moved away from each other to be separated from the guide rail 10 by the driving member 53 (see fig. 7 to 9, 11 to 13), that is, the clamping blocks 511 are locked with the surface of the guide rail 10 by static friction with the inward surface (the inward surface with respect to the other clamping block 511), or the two clamping blocks 511 are moved away from each other to be held tightly against the guide rail 10 or moved toward each other to be separated from the guide rail 10 by the driving member 53 (see fig. 10 and 14), that is, the clamping blocks 511 are locked with the surface of the guide rail 10 by static friction with the outward surface (the outward surface with respect to the other clamping block 511).

Referring to fig. 2 and 3, in an embodiment, the driving member 53 includes a driving motor 531 and a positive and negative screw rod 533 connected to each other, the two clamping blocks 511 are sleeved on the positive and negative screw rod 533, and the driving motor 531 drives the two clamping blocks 511 to approach each other or separate from each other through the positive and negative screw rod 533. Specifically, the driving end of the driving motor 531 is connected to one end of the positive and negative screw rod 533, the driving motor 531 is configured to drive the positive and negative screw rod 533 to rotate around its own axis, and in this process, the two clamping blocks 511 move along the axial direction of the positive and negative screw rod 533 along with the rotation of the positive and negative screw rod 533 in opposite directions, so as to tightly hold or separate the clamping blocks 511 from the guide rail 10.

Referring to fig. 5, in another embodiment, two clamping blocks 511 are hinged to be in a scissor shape, the guide rail 10 is located at an intersection of one end of the two clamping blocks 511, the driving member 53 includes a push rod motor 535, the push rod motor 535 is located at an intersection of the other end of the two clamping blocks 511, two ends of the push rod motor 535 are respectively connected with the two clamping blocks 511, and the push rod motor 535 is used for driving the two clamping blocks 511 to clamp the guide rail 10 or separate the guide rail 10 from the guide rail 10. Specifically, the opening size between the two clamping blocks 511 is changed by performing telescopic transformation on the push rod of the push rod motor 535, so that the clamping blocks 511 are tightly held or separated from the guide rail 10.
