Detailed Description

In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 and 2 together, a floating type sewage pump according to the present invention will now be described. The floating dredge pump comprises: the pump body 1, the suspension 3, the push plate 4, the counterweight 5, the elastic resetting piece 6 and the driving element 7. The suspension piece 3 is rotatably arranged on the pump body 1, and a first accommodating cavity 301 is formed inside the suspension piece 3; the push plate 4 is arranged in the first accommodating cavity 301 in a sliding manner, and the push plate 4 divides the first accommodating cavity 301 into an outer cavity 302 communicated with the outside and a closed inner cavity 303; the balance weight part 5 is fixedly connected with the push plate 4 and is positioned on the outer side of the suspension part 3; the elastic reset piece 6 is arranged between the push plate 4 and the suspension piece 3 and provides acting force opposite to the centrifugal force of the counterweight piece 5 for the push plate 4; the driving element 7 is fixedly arranged on the pump body 1 and used for driving the suspension part 3 to rotate; when the centrifugal force of the weight member 5 is larger than the elastic force of the elastic reset member 6, the push plate 4 slides outwards and extrudes the liquid in the outer cavity 302, and the suspension type sewage pump floats upwards; when the centrifugal force of the weight member 5 is smaller than the elastic force of the elastic restoring member 6, the push plate 4 slides inward and sucks the external liquid into the outer cavity 302, and the suspension type sewage pump sinks.

Compared with the prior art, the suspension type sewage pump provided by the invention has the advantages that the suspension piece 3 rotates on the pump body 1 under the driving action of the driving element 7, and meanwhile, the counterweight piece 5 is driven to rotate around the rotating shaft of the suspension piece 3; the push plate 4 divides the first accommodation chamber 301 into an outer chamber 302 and an inner chamber 303, and since the outer chamber 302 communicates with the outside, the outside liquid enters the outer chamber 302. The operator can adjust the rotational speed of the suspension 3 by controlling the drive element 7, the rotational speed of the suspension 3 being greater the centrifugal force of the counterweight 5, since the rotational speed is proportional to the centrifugal force. When the centrifugal force of the weight member 5 is greater than the elastic force of the elastic reset member 6, the weight member 5 drives the push plate 4 to move outwards, so that liquid in the outer cavity 302 is extruded out, the weight of the suspended sewage pump is reduced, and the suspended sewage pump floats upwards; when the centrifugal force of the weight member 5 is smaller than the elastic force of the elastic restoring member 6, the push plate 4 moves inward under the action of the elastic restoring member 6, thereby sucking the external liquid into the outer chamber 302, increasing the weight of the suspension type sewage pump, and the suspension type sewage pump sinks. The utility model provides a floated dredge pump adjusts the rotational speed of suspension 3 through control drive element 7, makes this floated dredge pump can come the come-up or sink, has reached the purpose of freely adjusting wading depth, has improved the blowdown effect.

In this embodiment, the suspension 3 is disc-shaped and is mounted on the top of the pump body 1; the axis of rotation of the suspension 3 is arranged in the vertical direction. The pump body 1 is of a closed structure and has a waterproof function, the driving element 7 is a motor, and the motor is placed inside the pump body 1, so that the motor is protected, the motor can normally work, and the service life of the motor is prolonged.

In order to facilitate the movement of the suspended sewage pump along the horizontal direction, a propeller can be further installed on the pump body 1, the propeller is an electric propeller, the electric propeller is rotatably connected to the side face of the pump body 1, and the angle of the electric propeller is changed through electric control, so that the suspended sewage pump can move in the horizontal direction.

When the rotating speed of the suspension piece 3 is increased, the centrifugal force of the weight piece 5 is increased, the weight piece 5 is gradually far away from the suspension piece 3 under the action of the centrifugal force, namely the rotating speed of the suspension piece 3 is higher, the distance between the weight piece 5 and the suspension piece 3 is larger, so that the contact area between the suspension type sewage pump and sewage is increased, the stability of the suspension type sewage pump is improved to the maximum extent, and the smooth and safe sewage discharge is ensured.

Referring to fig. 1 and 2, as an embodiment of the suspension type sewage pump provided by the present invention, a plurality of weight members 5 are uniformly arranged along a circumferential direction of the suspension member 3. In this embodiment, the number of the balance weights 5 is at least two, and the balance weights are uniformly arranged along the circumferential direction of the suspension member 3, so that the stress of the suspension member 3 is more balanced, and the stability of the suspension type sewage pump in the working state is improved. Besides granular impurities, other impurities such as branches and reinforcing steel bars can be doped in the sewage, and the balance weight piece 5 is located on the outer side of the suspension piece 3 and rotates around the central shaft of the suspension piece 3 along with the suspension piece 3, so that the balance weight piece 5 can push away or break the impurities in the sewage close to the suspension type sewage pump, and the large impurities are prevented from colliding with the pump body 1. The counterweight 5 is spherical, and the surface of the counterweight is a circular arc surface, so that the resistance of the counterweight 5 in the movement process is greatly reduced. The crushing knife 503 is installed on the outer peripheral surface of the weight 5, and the weight 5 can more effectively crush the block impurities in the sewage by the crushing knife 503, so that the pump body 1 is prevented from being blocked by the block impurities.

As a specific embodiment of the suspension type dredge pump provided by the present invention, please refer to fig. 1 and 2, the counterweight 5 is connected with the push plate 4 through a connecting rod 501, and a first through hole 304 slidably engaged with the connecting rod 501 is provided on the side wall of the outer cavity 302; a water trough 502 is provided on the outer wall of the connecting rod 501, and the water trough 502 is used for communicating the outer cavity 302 with the outside.

In this embodiment, the inflation/deflation pump 308 is fixedly installed on the top of the pump body 1. The inflation/deflation pump 308 inflates and deflates the balloon 307, thereby changing the volume of the balloon 307. When the inflation and deflation pump 308 inflates the air bag 307, the volume of the air bag 307 is increased, the liquid in the second accommodating cavity 305 is extruded to the outside through the second through hole 306, the weight of the suspension type sewage pump is reduced, and the suspension type sewage pump floats upwards; when the air pump 308 discharges the air in the air bag 307, the volume of the air bag 307 decreases, and the external liquid enters the second accommodating chamber 305, which increases the weight of the suspension type sewage pump, and the suspension type sewage pump sinks. The structure not only can further improve the ascending or sinking power of the suspension type sewage pump, but also can be used as standby equipment; when the driving element 7 is out of order, the standby device is started, thereby ensuring that the floating type sewage pump can smoothly complete floating or sinking.
