Embodiment 1

[0019] Such as figure 1 As shown, a safe anti-blocking sewage pump based on Bernoulli's principle includes a pump body 1, on which two water inlet pipes 2 arranged in parallel are installed, and the water inlet ends of the two water inlet pipes 2 are equipped with filter A net 3, a sealing box 4 is fixedly connected between the two water inlet pipes 2, a gear 5 rotates in the sealing box 4, and a wing plate 6 parallel to the axial direction of the water inlet pipe 2 is arranged in the two water inlet pipes 2, and the two wing plates The side walls of the plates 6 away from each other are in the shape of an arched arc, and the side walls close to each other are horizontal planes. The two wing plates 6 are arranged symmetrically about the central axis of the sealed box 4, and the connecting rod 7 is passed between the two wing plates 6. Fixed, the connecting rod 7 runs through the water inlet pipe 2 and the sealing box 4 and is in sealing and sliding connection with the water in...

Embodiment 2

[0023] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that: the inner side wall of the sealed box 4 is fixedly connected with a permanent magnetic strip 11, and the rotating shaft 9 is wound with a helical coil 12, and the winding direction of the helical coil 12 is consistent with the permanent magnetic strip 11. The direction of the magnetic induction line of the magnetic strip 11 is vertical, and a warning light 13 is installed on the pump body 1 .

[0024] In this embodiment, when the filter screen 3 at the port of one of the water inlet pipes 2 is blocked, the rotating shaft 9 drives the helical coil 12 to rotate, and the helical coil 12 continues to cut the magnetic field lines of the permanent magnetic strip 11 to generate an induced current to supply power to the warning light 13 , the warning light 13 emits light, which is convenient for the staff to quickly find the blockage problem, check it in time and perform anti-blocking t...

Abstract

The invention belongs to the technical field of water pumps, and in particular relates to a safe and anti-blocking sewage pump based on Bernoulli's principle, which includes a pump body on which two water inlet pipes arranged in parallel are installed. Filter screens are installed at the water inlet ends, and a sealed box is fixedly connected between the two water inlet pipes, and a gear rotates in the sealed box, and wings parallel to the axial direction of the water inlet pipes are provided in the two water inlet pipes. The two wing plates are arranged symmetrically with respect to the central axis of the sealed box, and the two wing plates are fixed by a connecting rod, and the connecting rod runs through the water inlet pipe and the sealed box and is sealed and slidably connected with the water inlet pipe. The connecting rod is provided with a tooth groove and meshed with a gear, and a rotating shaft is coaxially and fixedly connected inside the gear. The invention can change the pressure of the water flow through the wing plate to drive the cutting blade to rotate and cut the accumulated and clogged fibrous matter on the surface of the filter screen, so as to play a good role in dredging and preventing clogging, without the need for staff to check and clean up frequently.

Description

technical field [0001] The invention belongs to the technical field of water pumps, in particular to a safe anti-blocking sewage pump based on Bernoulli's principle. Background technique [0002] Sewage pumps are mainly used to transport urban domestic sewage or industrial wastewater. They have the advantages of compact structure, small footprint, and convenient installation and maintenance. Since urban domestic sewage contains a large number of fiber entanglements, anti-blocking and reliability are the advantages and disadvantages of sewage pumps. important factor. [0003] Because the sewage to be transported contains fibers that are easy to entangle or bunch, the flow path of the pump is easy to block. Once the pump is blocked, the pump will not work normally, and even the motor will be burned, resulting in poor sewage discharge, which brings great harm to urban life and environmental protection. Serious impact, so when dealing with urban sewage, generally before the sew...
