DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0024] Reference Figure 1-Figure 5 , a mine flameproof submersible sand discharge electric pump easy-to-disassemble device, comprising a pump body 1, a base 2 is provided on the lower surface of the pump body 1, a plurality of sand inlets 3 are provided on the surface of the base 2, and a sand discharge component is provided on the upper surface of the pump body 1;

[0025] The upper surface of the base 2 is symmetrically and vertically fixed with an insertion rod 4, and the lower surface of the pump body 1 is symmetrically and vertically provided with slots 5 for inserting two insertion rods 4 respectively. The upper surface of the base 2 is circumferentially fixed with a mounting plate 6, and the surface of the pump body 1 is circumferentially fixed with a plurality of fixing plates 7, and the surface of the fixing plate 7 is fixedly provided with an arc-shaped first spring rod 8, and the surface of the mounting plate 6 is provided with a locking port 9 for inserting the end of the first spring rod 8;

[0026] When the base 2 needs to be installed, first control the multiple first spring rods 8 to shrink, and then align the two insertion rods 4 with the two slots 5 and insert them until the upper surface of the base 2 abuts against the lower surface of the pump body 1. At this time, the ends of the multiple first spring rods 8 will correspond to the positions of the multiple locking openings 9 respectively, and then release the multiple first spring rods 8, the multiple first spring rods 8 will quickly stretch and recover, and the ends of the multiple first spring rods 8 will be respectively inserted into the multiple locking openings 9, thereby completing the installation of the base 2 and the pump body 1. When disassembling, it is only necessary to control the multiple first spring rods 8 to shrink so that the ends of the multiple first spring rods 8 are respectively moved out of the multiple locking openings 9 to release the lock between the pump body 1 and the base 2, which is convenient and quick.

[0027] A pull plate 10 is fixedly sleeved on the first spring rod 8, a rotating ring 11 is sleeved on the pump body 1, the lower surface of the rotating ring 11 is fixedly connected to the top ends of the plurality of pull plates 10, and a grip rod 12 is fixedly installed on the upper surface of the rotating ring 11;

[0028] When it is necessary to control the contraction of the plurality of first spring rods 8, it is only necessary to hold the handle 12 and then control the rotation of the rotating ring 11. At this time, the plurality of pull plates 10 will move together and respectively contract the plurality of first spring rods 8 together, which is convenient and quick.

[0029] A placement groove is vertically provided on the surface of the pump body 1, a slide bar 13 is vertically fixedly installed in the placement groove, a slider 14 is slidably sleeved on the slide bar 13, a locking rod 15 is fixedly installed on the lower surface of the slider 14, a locking groove 16 for inserting the end of the locking rod 15 is vertically provided on the top of the grip rod 12, a telescopic spring 17 is sleeved on the slide bar 13, and the two ends of the telescopic spring 17 are respectively fixedly connected to the upper surface of the slider 14 and the top wall of the placement groove;

[0030] When the ends of the plurality of first spring rods 8 are respectively inserted into the plurality of locking openings 9, the locking groove 16 at the top of the gripping rod 12 will correspond to the position of the locking rod 15, and then the bottom end of the locking rod 15 is controlled to be inserted into the locking groove 16 to complete the locking of the rotating ring 11. At this time, the rotating ring 11 can no longer rotate, and the plurality of first spring rods 8 can no longer be extended or retracted. When it is necessary to control the extension or retraction of the plurality of first spring rods 8, it is necessary to first control the slider 14 to move upward so that the end of the locking rod 15 is moved out of the locking groove 16. After the rotation ring 11 is unlocked, the first spring rod 8 can be controlled to be extended or retracted, which has a safety effect and prevents the plurality of first spring rods 8 from contracting due to the force of the external water flow during the operation of the device, thereby causing the lock between the pump body 1 and the base 2 to be released.

[0031] A straight rod 24 is fixedly mounted on one end of the first spring rod 8. The surface of the straight rod 24 is provided with threads. A limit nut 25 is threadedly mounted on the straight rod 24. The size of the limit nut 25 is larger than the size of the locking port 9.

[0032] When one end of the first spring rod 8 passes through the locking opening 9 with the straight rod 24, the limiting nut 25 is threadedly installed on the straight rod 24. Since the size of the limiting nut 25 is larger than the size of the locking opening 9, the end of the first spring rod 8 can never be moved out of the locking opening 9, which again plays a safety role and improves the stability of the installation of the pump body 1 and the base 2. Only when the limiting nut 25 is unscrewed from the straight rod 24, the end of the first spring rod 8 can be moved out of the locking opening 9 with the straight rod 24.

[0033] The sand discharge component includes a mounting seat fixedly mounted on the top of the pump body 1, a hollow rod 18 vertically fixedly mounted on the upper surface of the mounting seat, and a sand discharge pipe 19 with a sliding sealing sleeve arranged on the hollow rod 18. The sand discharge pipe 19 is locked by a locking assembly, which includes two second spring rods 20 respectively fixedly mounted on the left and right side walls of the mounting seat, two movable plates 21 respectively fixedly mounted on the ends of the two second spring rods 20, and two round rods 22 respectively fixedly mounted on the surfaces of the two movable plates 21. A plurality of positioning grooves 23 for inserting the ends of the round rods 22 are symmetrically provided on the surface of the sand discharge pipe 19;

[0034] By controlling the two second spring rods 20 to stretch, the ends of the two round rods 22 are respectively moved out of the two positioning grooves 23, and the lock of the sand discharge pipe 19 can be released at this time. Then, the sand discharge pipe 19 is controlled to move in the vertical direction to change the length of the sand discharge component. When the appropriate length is reached, the two second spring rods 20 are released. The two round rods 22 will quickly move and reset under the elastic potential energy of the two second spring rods 20, and are respectively inserted into the two positioning grooves 23 corresponding to their own end positions, thereby completing the locking of the sand discharge pipe 19 position. The height position of the sand discharge component is no longer constant, and its height can be adjusted, which is convenient for external pipeline equipment and improves the practicability of the device.

[0035] In the utility model, when the base 2 needs to be installed, the multiple first spring rods 8 are first controlled to contract, and then the two insertion rods 4 are respectively aligned with the two slots 5 and inserted until the upper surface of the base 2 is against the lower surface of the pump body 1. At this time, the ends of the multiple first spring rods 8 will respectively correspond to the positions of the multiple locking openings 9, and then the multiple first spring rods 8 are released, and the multiple first spring rods 8 will be quickly stretched and restored, and the ends of the multiple first spring rods 8 will be respectively inserted into the multiple locking openings 9, thereby completing the installation of the base 2 and the pump body 1. When disassembling, it is only necessary to control the multiple first spring rods 8 to contract so that the ends of the multiple first spring rods 8 are respectively moved out of the multiple locking openings 9 to release the lock between the pump body 1 and the base 2. It is convenient and quick, avoids the cumbersome steps of using screw and nut fixings, and improves the work efficiency of disassembling and assembling the base 2.

[0036] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
