DETAILED DESCRIPTION

[0023] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model.

[0024] Please refer to Figs. 1-4The utility model provides a sewage suction pump system of sewage suction truck, including pump machine 1, one side of pump machine 1 is fixedly installed with fixed sleeve 11, one side of fixed sleeve 11 is fixedly installed with motor 2, the inside fixed mounting of pump machine 1 has accommodating cylinder 12, the inside fixed mounting of pump machine 1 is located accommodating cylinder 12 one side and is installed with chuck 13, the top of pump machine 1 is equipped with water outlet 14, the other side of pump machine 1 is equipped with water inlet 15, the end of water inlet 15 is connected with sewage suction pipe 3, the outside circle of accommodating cylinder 12 rotates sleeve joint with rotating sleeve 4 in the inside of pump machine 1, rotating sleeve 4 rotates sleeve joint in the outside circle of chuck 13.

[0025] By using the device, when the sewage suction work is carried out, the filter bag 33 can filter part of the garbage in the sewage, when the garbage blocks the bottom of the filter bag 33, the sewage can be filtered from the upper part of the filter bag 33 into the inside of the sewage suction pipe 3, so that when the sewage is preliminarily filtered, the circulation of the sewage is not affected, and the sewage suction amount of the pump machine 1 is increased.

[0026] When the garbage or particles in the sewage block or wind the fan blade 41, the rotating speed of the rotating sleeve 4 can be slowed down, but the design of the magnetic head 21 and the rotating sleeve 4 will not make the motor run under load, if the rotating resistance of the rotating sleeve 4 is greater than the torque between the rotating sleeve 4 and the magnetic head 21, the magnetic head 21 will idle, will not work under load, and the motor will not be burned out, and since the rotating torque of the magnetic head 21 is not consumed, the rotating speed is relatively fast, the staff can timely notice that the fan blade 41 is wound, can timely check and maintain.

[0027] Please refer to Figs. 1-4 The end of the output shaft of the motor 2 is fixedly connected with the magnetic head 21 in the inner circle of the accommodating cylinder 12, and the magnetic head 21 is a rare earth magnet.

[0028] By arranging the magnetic head 21 and the rotating sleeve 4, magnetic force is used to drive rotation, when the magnetic head 21 rotates, the magnetic poles of the magnetic head 21 and the rotating sleeve 4 are attracted to each other, so that the rotating sleeve 4 can be driven to rotate synchronously, and when the pump machine 1 pumps water, high-speed rotation and large torque are not needed, and the magnetic force transmission between the magnetic head 21 and the rotating sleeve 4 is enough to drive the pump machine 1 to pump water.

[0029] Please refer to Figs. 1-4 The end of the sewage suction pipe 3 is slidably sleeved with the connecting sleeve 31, the inner circle of the connecting sleeve 31 is provided with a threaded groove, the outer circle of the water inlet 15 is provided with a thread, the threaded groove in the inner circle of the connecting sleeve 31 is matched with the thread on the outer circle of the water inlet 15, the other end of the sewage suction pipe 3 is provided with a flange plate 32, the sewage suction pipe 3 is connected with an external water pipe, the filter bag 33 is clamped in the inside of the sewage suction pipe 3, the filter holes are uniformly arranged in the outer circle of the filter bag 33 in a circular ring shape, the diameter of the filter bag 33 is smaller than that of the sewage suction pipe 3, and there is a gap between the outer circle of the filter bag 33 and the inner circle of the sewage suction pipe 3.

[0030] The filter bag 33 is provided to preliminarily filter the garbage in the sewage. Since there is a gap between the outer ring of the filter bag 33 and the inner ring of the suction pipe 3, when the bottom of the filter bag 33 is blocked by garbage, the upper outer ring of the filter bag 33 can still allow the sewage to enter the inside of the suction pipe 3 from the upper filter hole, thereby filtering into the inside of the fixed sleeve 11.

[0031] Please refer to Figs. 1-4 The outer ring of the rotating sleeve 4 is uniformly fixed and installed with the fan blades 41 in a circular ring shape. The rotating sleeve 4 is made of a rare earth magnet matched with the magnetic head 21. The rotating sleeve 4 is separated from the magnetic head 21 by the containing cylinder 12, but does not affect the magnetic attraction between the magnetic head 21 and the rotating sleeve 4. The fan edges of the fan blades 41 are uniformly provided with sharp knives 42 in a circular ring shape. The inner ring of the pump 1 is provided with a knife groove 16. The sharp knives 42 correspond to the knife groove 16. When the sewage is sucked, the garbage such as the rope inside the sewage is wound. The sharp knives 42 can cut off the rope or send it into the water outlet 14 to be discharged.

[0032] The magnetic attraction between the rotating sleeve 4 and the magnetic head 21. When the sewage carrying garbage enters the inside of the pump 1, the magnetic head 21 drives the rotating sleeve 4 and the fan blades 41 to rotate synchronously. When the garbage is wound around the fan blades 41 to increase the rotating load of the fan blades 41, the resistance of the rotating fan blades 41 is greater than the torque of the magnetic head 21. The magnetic head 21 will idle to avoid the load of the fan blades 41 being transmitted to the motor 2 to burn the motor 2. This structure avoids burning the motor 2 when the load is too large, thereby reducing maintenance.

[0033] Working principle: connect the sewage pipe inside the sewage to one end of the suction pipe 3 and fix it by the flange plate 32. After the sewage enters the inside of the filter bag 33, the garbage will be preliminarily filtered by the filter bag 33. When the garbage blocks the bottom of the filter bag 33, the sewage can still enter the inside of the suction pipe 3 from the upper filter hole of the filter bag 33, so that the sewage discharge capacity is not reduced. Start the motor 2. The motor 2 drives the magnetic head 21 to rotate through the output shaft. The magnetic head 21 drives the rotating sleeve 4 to rotate synchronously through the magnetic attraction. The rotating sleeve 4 spirally transports the sewage in the pump 1 to the inside of the water outlet 14 to perform the sewage suction work. When the sewage and garbage are wound around the fan blades 41, the rotating load of the fan blades 41 is too large. The magnetic head 21 will idle. At this time, since the magnetic head 21 does not have resistance and transmission during rotation, the rotating speed of the magnetic head 21 will increase. At this time, the workers can repair and check the inside of the pump 1 according to the change, thereby avoiding the effect of burning the motor.
