[0001] The utility model relates to a labor-saving steering mechanism of manual photovoltaic cleaning equipment belongs to the technical field of photovoltaic cleaning equipment. BACKGROUND

[0002] With the vigorous development of clean energy of the country, more and more photovoltaic panels will convert solar energy into electric energy for application. Photovoltaic panels need to be cleaned frequently to ensure the conversion rate of solar energy. The existing photovoltaic cleaning equipment usually adopts a telescopic rod type structure to drive a disc brush or a roller brush for manual cleaning, which is heavy and cannot realize steering function, and the cleaning efficiency is low. Another is an electric control structure, which has high cost, complex structure and high maintenance cost.

[0003] Because the photovoltaic panel has a certain inclination angle, when manually cleaning, the included angle between the cleaning equipment and the push rod is very small, and the existing steering assist structure in other fields is not suitable for the small included angle structure of the push rod and the cleaning equipment. SUMMARY

[0005] To solve the above problems, the specific technical scheme of the utility model is as follows: a labor-saving steering mechanism of manual photovoltaic cleaning equipment, including bevel gear assist mechanism, rotary push rod connecting mechanism and rotating mechanism, wherein the bevel gear assist mechanism includes mutually meshing large and small bevel gears, and the large bevel gear is fixedly connected with the base; the rotary push rod connecting mechanism includes a rotary push rod, a shaft coupling and a bearing seat, one end of the shaft coupling is connected with the rotary push rod, and the other end is coaxially matched with the shaft of the small bevel gear passing through the bearing seat; a rotating shaft coaxially arranged with the large bevel gear is arranged on the base, the rotating shaft is matched with a turntable through a bearing, and the bottom of the bearing seat is fixed on the turntable.

[0006] A limiting frame is arranged at the connection between the rotary push rod and the shaft coupling, the rotary push rod is located in the limiting frame, and the rotary push rod is limited in the transverse movement range relative to the limiting frame.

[0007] The turntable is an outer turntable, the outer turntable is located below the large bevel gear, and one side of the outer turntable extends outward and is connected with the bearing seat.

[0008] The outer turntable is connected with the bearing seat and is connected with a mounting disc, and the mounting disc is connected with the limiting frame.

[0009] The turntable is an inner turntable, the inner turntable is located at the center of the large bevel gear, and the bearing seat and the limiting frame are arranged on the upper surface of the inner turntable.

[0010] The manual photovoltaic cleaning equipment of this application employs the above-described structure in its labor-saving steering mechanism, which has the following advantages:

[0011] 1. Through the cooperation of two bevel gears, rotating the push rod can realize the rotation of the push rod and the bottom frame, thereby completing the power steering;

[0012] 2. The transmission structure using two bevel gears can adapt to the problem of small working angle of the push rod, ensuring the comfort of the workers.

[0013] 3. A coupling is installed to connect the rotary push rod and the small bevel gear, which not only achieves an effective connection, but also does not affect the swing of the rotary push rod;

[0014] 4. A limit frame is provided on the rotary push rod to further restrict the lateral movement of the rotary push rod, so that the rotary push rod can only rotate and swing up and down. Attached Figure Description

[0018] Figure 4 for Figure 3 Axial sectional view. Detailed Implementation Example 1

[0019] like Figure 1 and Figure 2 As shown, a labor-saving steering mechanism for a manual photovoltaic cleaning device includes a bevel gear assist mechanism, a rotary push rod connection mechanism, and a rotating mechanism. The bevel gear assist mechanism includes a large bevel gear 1 and a small bevel gear 2 that mesh with each other. The large bevel gear 1 is fixedly connected to a base 6. The rotary push rod connection mechanism includes a rotary push rod 3, a coupling 4, and a bearing seat 5. One end of the coupling 4 is connected to the rotary push rod 3, and the other end is coaxially engaged with the shaft of the small bevel gear 2 passing through the bearing seat 5. A limiting frame 9 is provided at the connection between the rotary push rod 3 and the coupling 4. The rotary push rod 3 is located within the limiting frame 9, limiting its lateral movement relative to the limiting frame 9. The rotary push rod 3 only has rotational and up-and-down swinging movements. A rotating shaft 7, coaxially arranged with the large bevel gear 1, is provided on the base 6. The rotating shaft 7 is engaged with a turntable 8 via a bearing. The bottom of the bearing seat 5 is fixed to the turntable 8. The turntable 8 is an outer turntable, located below the large bevel gear 1, and one side of the outer turntable extends outward to connect with the bearing seat 5. The outer turntable is connected to the bearing housing 5 and the mounting plate 10 is connected to the upper surface of the mounting plate 10. The limiting frame 9 is connected to the upper surface of the mounting plate 10.

[0020] When in use, when the handheld rotary push rod 3 is manually twisted during the pushing process, the handheld rotary push rod 3 drives the small bevel gear 2 to rotate through the coupling 4. The small bevel gear 2 drives the large bevel gear 1 to rotate. At the same time, the limiting frame 9 restricts the horizontal movement of the rotary push rod 3, so that the rotary push rod 3 can rotate arbitrarily while only moving up and down within the limiting frame. This can drive the equipment on the base to turn, achieving the purpose of saving effort, and can also precisely control the rotation direction of the equipment. Example 2

[0021] like Figure 3 and Figure 4 As shown, in the labor-saving steering mechanism of the manual photovoltaic cleaning equipment in this embodiment, the turntable 8 is an inner turntable, located at the center of the large bevel gear 1. The inner turntable and the mounting plate are combined into one, and the bearing seat 5 and the limiting frame 9 are jointly arranged on the upper surface of the inner turntable. The rest of the structure is the same as in Embodiment 1.

[0022] The structure of this embodiment is more compact.

[0023] In addition to being installed on manual photovoltaic cleaning equipment, the labor-saving steering mechanism of this application can also be installed on other equipment that requires manual steering.
