Description

Impurity removing device for irrigation submersible pump

Technical Field

The utility model relates to the field of irrigation equipment, in particular to an impurity removing device for an irrigation submersible pump.

Background

Submersible pumps are specially designed pumps for pumping liquids (typically water) from deep water or downhole to the surface or higher, and are often used in the field of farm irrigation. The submersible pump is structurally and operationally composed of a pump body shell, a motor, an impeller and the like, wherein the motor is positioned at the upper part or the lower part of the pump body and is usually sealed and waterproof so as to protect the motor from water invasion. The impeller is mounted on the shaft of an electric motor, typically a centrifugal or agitator impeller, and is rotated to draw liquid. The pump body housing is structured to deliver liquid from the pump body to a desired location. It can be seen that the submersible pump achieves pumping of liquid from deep water levels or downhole to a desired location through a continuous rotation and suction-push-out cycle. While the submersible pump is usually provided with an annular water suction port, and a circle of metal filter plates are arranged outside the water suction port to prevent sundries from being sucked in.

Reference may be made to the prior art, patent publication No.: CN115750396a, patent name: an impurity blocking device for a submersible pump can be seen to use turbine blades to cut, thereby preventing clogging. However, this method is difficult to remove foreign matters adsorbed on the outer side of the water suction port, so that the structure cannot solve the problem of affecting water inflow if the submersible pump is used in an open water area. The inventor proposes a trash remover which can remove sundries through a reducing structure to solve the problems.

The following are only preferred embodiments of the present utility model, and are not intended to limit the scope of the present utility model, which is further described with reference to the accompanying drawings and examples.

Example 1:

referring to fig. 1-5, the submersible pump comprises a submersible pump body 1, an outer hanging bracket 2 and a impurity removing component 3.

In this embodiment, the submersible pump body 1 includes a pump housing 4 vertically disposed, a motor 15 disposed at a lower portion of the pump housing 4, an impeller 14 disposed at an upper portion of the pump housing 4, and an annular water suction port 5 disposed at a middle portion of the pump housing 4. As in the prior art, the submersible pump body 1 is driven by the impeller 14 through the built-in pump body shaft 16, and water is discharged from the water outlet (water outlet communication pipe) at the top end of the pump casing 4. In the use process, the whole submersible pump body 1 is enabled to enter water, the annular water suction port 5 in the middle is enabled to enter water, and therefore an annular filter screen 13 is arranged at the annular water suction port 5.

In order to strengthen the stability of the submersible pump in the application of an open water area, the whole submersible pump body 1 is convenient to be matched with a crane, and an outer hanging frame 2 is arranged outside the submersible pump body 1. The outer hanger 2 includes an outer bracket 6 surrounding and fixedly coupled to the pump housing 4, a reinforcing leg 7 provided at the bottom of the outer bracket 6, and a first hanger 8 provided at the top of the outer bracket 6. Wherein, outer gallows 2 is polygonal frame, and it is fixed with the pump body shell. The reinforcing legs 7 are provided with four inclined struts, and the first suspension member 8 can be matched with a winch to drive the submersible pump body 1 to lift.

The first hanger 8 includes a pair of coupling seats 23 symmetrically provided at both left and right sides of the outer hanger 2 and a first pulley 24 hinged to the coupling seats 23, and the inner side of the elevation seat 9 extends inward and is fixedly coupled with the pump housing 4.

In the scheme, the impurity removing component 3 utilizes a reducing form to remove impurities adsorbed on the annular filter screen 13 by the annular water absorbing port 5. The rotary seat comprises a lifting seat 9 coaxially arranged with an annular water suction port 5, a rotary seat 10 concentrically and rotatably connected with the lifting seat 9, a plurality of reducing adjusting shafts 11 uniformly distributed along the circumferential direction of the rotary seat 10, and a power source 12 for driving the rotary seat 10 to rotate. Specifically, four vertical guide rails 21 are provided on the peripheral side of the outer hanger 2, the guide rails 21 are square tubes and are grooved on one side, and lifting pulleys 22 matched with the guide rails 21 are provided on the peripheral side of the lifting seat 9. The lifting seat 9 can slide up and down by means of the guide rail 21, and is provided with a second suspension piece 19, and the second suspension piece 19 and the first suspension piece 8 have the same function and can be driven to lift by a winch on the shore. Specifically, the second suspension 19 is two second pulleys provided on the upper side of the elevating seat 9.

As can be seen from fig. 2, the rotating seat 10 and the lifting seat 9 are of a slewing bearing structure, and can relatively rotate and are coaxial with the annular water suction port 5. Three gantry-shaped hinging seats are arranged on the periphery of the rotating seat 10, and a linear guide piece 18 is hinged, wherein the linear guide piece 18 is an axial horizontal sleeve for guiding horizontal linear motion. The reducing adjustment shaft 11 is slidably mounted in a linear guide 18, and is hinged at its outer end to the rotary base 10 and mounted at its inner end with a scraping blade 20.

As can be seen from fig. 3 to 5, the diameter-variable adjusting shafts 11 are axially and horizontally arranged, and the diameter of the fitting circle of the inner end points of the plurality of diameter-variable adjusting shafts 11 is changed by the relative rotation of the rotating seat 10 and the lifting seat 9. Therefore, the scraping shovel 20 at the tail end of the scraper can be attached to the annular filter screen 13 outside the annular water suction port 5 to remove impurities, and impurities can be taken away when the scraper is pulled outwards.

The power source 12 is used for controlling the relative rotation of the rotary seat 10 and the lifting seat 9, and comprises a driving seat 25 rotatably installed at the bottom of the lifting seat 9, a screw rod 17 rotatably installed on the driving seat 25, an adjusting motor 26 in transmission connection with the screw rod 17, a transmission seat 28 rotatably installed on the rotary seat 10 and a nut seat 27 arranged on the transmission seat 28. It can be seen that the screw 17 is horizontally arranged, the rotation axes of the driving seat 25 and the transmission seat 28 are vertical, and the nut seat 27 is in threaded transmission connection with the screw 17. Thus, the relative distance between the driving seat 25 and the transmission seat 28 can be controlled by the rotation of the adjusting motor 26, so as to drive the rotating seat 10 to rotate.

In this embodiment, the scraping shovel 20 has a tile-shaped structure tapered downward, and the lower end thereof is a free end, and the scraping shovel 20 may be made of nylon, engineering plastic or metal material having elasticity. In other embodiments, a metal brush that approximates a tile may be used instead.

For the use of the device, devices such as a crane and a winch on the shore are required to be used for placing and lifting like a traditional submersible pump, the device can drive the impeller 14 to absorb water through the motor 15 when in use, after a period of use or when the flow is obviously reduced, the second suspension piece 19 is downwards moved by adopting another independent winch on the shore, the rotating seat 10 of the impurity removal assembly 3 is controlled to rotate in the process, the scraping shovel 20 is attached to the annular water absorption port 5 as much as possible to remove impurities, and thus, the submersible pump can be stopped and lifted for multiple times to remove impurities, so that the operation time is greatly saved and the use complexity is reduced.

The utility model and its embodiments have been described above with no limitation, and the actual construction is not limited to the embodiments of the utility model as shown in the drawings. In summary, if one of ordinary skill in the art is informed by this disclosure, a structural manner and an embodiment similar to the technical solution should not be creatively devised without departing from the gist of the present utility model.
