[0015] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0016] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0017] Example

[0018] Please refer to the attached drawings of the specification. In the embodiment of the utility model, a hand-push water pump derrick comprises a base frame 1, a diagonal support frame 2 is fixedly connected to the base frame 1, a movable frame 11 is rotatably installed at the other end of the diagonal support frame 2, a stopper 12 which serves as a limit for the movable frame 11 is fixedly arranged at the end of the diagonal support frame 2, a rotating shaft 3 is rotatably installed on the diagonal support frame 2, three groups of circular baffles 4 are fixedly installed in parallel on the rotating shaft 3, and the three groups of baffles 4 divide the rotating shaft 3 into two sections, one of which is used for winding the water pump cable, and the other section is used for winding the agricultural tank water pipe;

[0019] A driving shaft 5 and a winch drum 7 are rotatably installed on the base frame 1. The winch drum 7 is used to wind the wire rope for hanging the water pump. One end of the driving shaft 5 is connected to a crank 6, and the other end is fixedly installed with a sprocket. The rotating shaft 3 and the same end of the driving shaft 5 are also fixedly installed with a sprocket and are connected to each other through a chain; a driving gear 8 is fixedly installed on the end of the driving shaft 5 close to the crank 6, and a passive gear 9 is fixedly installed on the end of the winch drum 7 close to the crank 6. The driving gear 8 and the passive gear 9 are meshed with each other, and a wheel 10 is installed on the base frame 1 through a bracket; a cross bar 13 is fixedly provided on one side of the driving shaft 5 on the base frame 1, a torsion spring 14 is installed on the cross bar 13, and a ratchet 15 is installed on the torsion spring 14. The movable end of the ratchet 15 is stuck in the tooth gap of the driving gear 8, and the ratchet 15 can prevent the driving shaft 5 from reversing after the hand releases the crank 6, thereby ensuring that the water pump can be stably suspended.

[0020] In particular, the diagonal support frame 2 is fixedly connected to the base frame 1 by welding; the driving shaft 5 and the hoisting drum 7 are rotatably mounted on the base frame 1 through bearings and bearing seats; the rotating shaft 3 is rotatably mounted on the diagonal support frame 2 through bearings and bearing seats.

[0021] Usage process:

[0022] When in use, the driving shaft 5 is manually rotated by the crank 6, and the driving shaft 5 rotates the winch drum 7 through the meshing transmission between the driving gear 8 and the passive gear 9. The winch drum 7 realizes the lifting and lowering of the water pump when winding or releasing the wire rope. The other end of the winch drum 7 drives the rotating shaft 3 to rotate in the same direction through the sprocket chain, so that the lifting and lowering of the water pump can be achieved while the cable and the agricultural tank water pipe are wound and released.

[0023] During the above process, wheels are installed on the base frame. During irrigation, farmers can push the derrick directly from their homes to the farm well operation site. The operation is simple and can be completed by one person, saving manpower. The cables and farm water pipes can be reeled in on both sides of the middle baffle on the rotating shaft. When the water pump in the well is raised or lowered, the wire rope, water pump cable, and farm water pipe can be manually raised or lowered synchronously in an integrated manner, saving labor and facilitating irrigation. The present application has a simple structure, strong practicability, and simple operation, which is worthy of promotion.
