Description

Technical Field

[0001] This utility model belongs to the field of submersible pump technology, specifically a portable submersible pump. Background Technology

[0002] Portable submersible pumps achieve liquid transfer through negative pressure, with core parameters including suction head, flow rate, and discharge head. Their structure consists of a drive unit and a pump body, and their size is much smaller than conventional water pumps. They are classified by drive voltage (AC or DC) and by working principle (diaphragm, piston, magnetic drive, etc.). Common types include DC brushed miniature diaphragm pumps and brushless magnetic pumps, suitable for transferring liquids including water, oil, and corrosive media.

[0003] A patent with publication number CN109268280A discloses a portable submersible pump, which includes a pump casing and a pump end cover located at the end of the pump casing and fixedly connected to the pump casing by bolts. The end of the pump end cover has a drain port, and the side wall of the pump casing has a water inlet. A water inlet filter is fixedly installed at the water inlet by bolts. A pump handle is fixedly installed on the outer wall of the pump casing. A power source, specifically a motor, is located inside the pump casing. The output shaft of the motor is connected to the pump shaft. An open impeller is located at the lower end of the pump shaft inside the pump end cover. The open impeller is fixedly locked to the pump shaft by an impeller locking nut. An oil chamber, fixed to the pump end cover, is located above the open impeller. An oil chamber end cover is located at the lower end of the oil chamber. Mechanical seals are provided on the pump shaft at the oil chamber and at the point where it mates with the pump end cover. The device provided by this invention is small in size, lightweight, and easy to carry.

[0004] Currently, existing portable submersible pumps are suitable for shallow to medium-depth water sources. However, the water layer inside these sources is quite shallow, causing the pump to easily touch the bottom when placed in the water. This causes the pump to tip over, resulting in its inlet being directly buried in the silt layer. Consequently, when the pump is pumping water, it draws in a large amount of silt, clogging the silt filter layer inside the pump. This clogging prevents the pump from being cleaned in time, increasing the pump load and affecting its pumping efficiency.

[0005] Therefore, a portable submersible pump is proposed to address the above problems. Utility Model Content

[0006] To overcome the shortcomings of existing technologies and solve the aforementioned problems, a portable submersible pump is proposed.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A portable submersible pump of this utility model includes a portable water pump and a protective sleeve that is detachably installed on the outer surface of the portable water pump. A pull rope is provided on the outer surface of the portable water pump, and a rope coiler is provided on the other end of the pull rope. Multiple sets of swing rods are evenly distributed and oscillatingly connected on the outer surface of the protective sleeve. A silt-adhering plate is fixedly connected to one end of the swing rod. A sliding rod is movably sleeved on the bottom surface of the protective sleeve. An impact plate is fixedly connected to the bottom surface of the sliding rod. A push shell is provided at the other end of the sliding rod and inside the protective sleeve. The top surface of the push shell movably overlaps the surface of one end of the swing rod.

[0008] Preferably, a water inlet is provided on the top outer surface of the protective sleeve, and a slot is provided on the outer surface of the protective sleeve at the bottom edge.

[0009] Preferably, the outer surface of the swing rod is movably sleeved on the inner wall of the slot, and the top inner wall of the protective sleeve is detachably mounted on the outer surface of the portable water pump.

[0010] Preferably, a water pump snap-fit ​​sleeve is provided on the outer surface of the portable water pump and on the top surface of the protective sleeve, and a connector snap-fit ​​cover head is fixedly connected to the output end of the portable water pump and is movably sleeved on the inner wall of the water pump snap-fit ​​sleeve.

[0011] Preferably, a movable frame is fixedly installed on the outer surface of the rope coiler, and a support plate is fixedly connected to the top surface of the movable frame at one side edge.

[0012] Preferably, a water pipe clamping plate is fixedly installed on the inner wall of the support plate at the middle position, and a water pipe is movably sleeved on the inner wall of the water pipe clamping plate, with one end of the water pipe being detachably sleeved on the outer wall of the connector clip cover.

[0013] Preferably, a plurality of auxiliary rollers are provided on the top outer surface of the support plate, and a swing arm plate is movably sleeved on the outer surface of the auxiliary rollers.

[0014] Preferably, the outer surface of the pull rope is movably overlapped with the outer surface of the auxiliary roller, and the positions of the two sets of auxiliary rollers are set on the outer surface of the swing arm plate.

[0015] The beneficial effects of this utility model are:

[0016] This utility model provides a portable submersible pump that is lowered by a rope coiler using a pull rope, allowing the portable water pump to descend vertically. A protective sleeve on the outer surface of the portable water pump further increases the weight at its bottom, enabling it to descend vertically. This design lowers the pump's center of gravity, preventing it from tilting or collapsing upon hitting the bottom due to water pressure or external forces.

[0017] This utility model provides a portable submersible pump. When the portable water pump and protective sleeve are lowered, the mud-adhesive plates on one end of multiple swing rods are pushed upward by the reverse force of the water source, causing the swing rods to swing upward and the other end of the swing rods to press down on the push sleeve, pushing the slide rod to the lowest position. When the protective sleeve contacts the bottom of the mud, the contact area with the bottom of the mud is increased by the contact impact plate on the bottom surface of the slide rod, so that the contact impact plate will not directly insert into the mud, thereby reducing the possibility of the portable water pump's inlet directly contacting the mud and causing blockage.

[0018] This utility model provides a portable submersible pump. Under the downward pressure of the portable water pump and the protective sleeve, the impact plate will push the sliding rod and the push sleeve in the opposite direction, causing the push sleeve to lift and squeeze one end of the swing rod, and causing the silt-adhesive plate on the other end of the swing rod to adhere to the surface of the silt bottom layer. The use of multiple sets of swing rods increases the contact range between the protective sleeve and the silt surface, and the use of the lower center of gravity of the protective sleeve prevents the portable water pump and the protective sleeve from tilting, shaking and collapsing.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Specific implementation examples are given below.

[0028] Please see Figure 1 - Figure 5 This utility model provides a portable submersible pump, including a portable water pump 12 and a protective sleeve 13 detachably mounted on the outer surface of the portable water pump 12. A pull rope 116 is provided on the outer surface of the portable water pump 12, and a rope coiler 115 is provided on the other end of the pull rope 116. Multiple swing rods 133 are evenly distributed and oscillatingly connected on the outer surface of the protective sleeve 13. A silt-adhering plate 134 is fixedly connected to one end of the swing rod 133. A sliding rod 135 is movably sleeved on the bottom surface of the protective sleeve 13. An impact plate 136 is fixedly connected to the bottom surface of the sliding rod 135. A push shell 137 is provided at the other end of the sliding rod 135 and inside the protective sleeve 13. The top surface of the push shell 137 movably overlaps the surface of one end of the swing rod 133.

[0029] During operation, the rope coiler 115 is used to lower the pull rope 116, allowing the portable water pump 12 to descend vertically. At this time, the protective sleeve 13 on the outer surface of the portable water pump 12 increases the weight at the bottom of the portable water pump 12, enabling the portable water pump 12 to move down vertically. This achieves the goal of lowering the center of gravity of the portable water pump 12 by using the protective sleeve 13, so that when the portable water pump 12 descends, it will not tilt or collapse when it touches the bottom due to the push of the water source or external force.

[0030] When the portable water pump 12 and the protective sleeve 13 descend, the mud-adhesive plates 134 on one end of the multiple swing rods 133 are pushed upward by the reverse force of the water source, causing the swing rods 133 to swing upward. The other end of the swing rods 133 presses down on the push sleeve 137, pushing the slide rod 135 to the lowest position. When the protective sleeve 13 contacts the bottom of the mud, the contact area with the bottom of the mud is increased by the contact impact plate 136 on the bottom surface of the slide rod 135, so that the contact impact plate 136 will not directly insert into the mud, thereby reducing the possibility that the water inlet of the portable water pump 12 will directly contact the mud and cause blockage.

[0031] Under the downward pressure of the portable water pump 12 and the protective sleeve 13, the impact plate 136 will push the slide rod 135 and the push sleeve 137 in the opposite direction, and cause the push sleeve 137 to lift and squeeze one end of the swing rod 133, and cause the mud-adhesive plate 134 on the other end of the swing rod 133 to adhere to the surface of the mud bottom layer. The multiple sets of swing rods 133 increase the contact range between the protective sleeve 13 and the mud surface, and the lower center of gravity of the protective sleeve 13 prevents the portable water pump 12 and the protective sleeve 13 from tilting, shaking and collapsing.

[0032] Furthermore, such as Figure 1 and Figures 3 to 5 As shown, a water inlet 131 is provided on the top outer surface of the protective sleeve 13, and a slot 132 is provided on the outer surface of the protective sleeve 13 at the bottom edge. The outer surface of the swing rod 133 is movably sleeved on the inner wall of the slot 132, and the top inner wall of the protective sleeve 13 is detachably installed on the outer surface of the portable water pump 12.

[0033] When the portable water pump 12 is in operation, external water will be directly pumped into the protective sleeve 13 through the water inlet 131 on the surface of the protective sleeve 13. The narrow gap of the water inlet 131 can effectively reduce the possibility of external solid impurities, branches, plastic bags and small fish directly entering the protective sleeve 13 and clogging the water inlet of the portable water pump 12.

[0034] Furthermore, such as Figures 1 to 3As shown, a water pump snap-fit ​​housing 117 is provided on the outer surface of the portable water pump 12 and on the top surface of the protective sleeve 13. A connector snap-fit ​​cover 118 is fixedly connected to the output end of the portable water pump 12 and is movably fitted onto the inner wall of the water pump snap-fit ​​housing 117. A movable frame 11 is fixedly installed on the outer surface of the rope coiler 115. A support plate 111 is fixedly connected to the top surface of the movable frame 11 and on one side edge. A [missing information - likely a device or component] is fixedly installed on the inner wall of the support plate 111 and in the middle position. A water pipe clamping plate 112 has a water pipe movably sleeved on its inner wall. One end of the water pipe is detachably sleeved on the outer wall of the connector clip cover 118. Multiple sets of auxiliary rollers 113 are provided on the top outer surface of the support plate 111. A swing arm plate 114 is movably sleeved on the outer surface of the auxiliary rollers 113. The outer surface of the pull rope 116 is movably overlapped on the outer surface of the auxiliary rollers 113. The positions of the two sets of auxiliary rollers 113 are set on the outer surface of the swing arm plate 114.

[0035] When using the portable water pump 12, the mobile frame 11 is moved to the water's edge. At this time, the swing arm plate 114 is swung on the surface of the support plate 111, and one end of the swing arm plate 114 is extended to the top of the water source at a distance. At this time, the rope coiler 115 is used to extend and rotate the pull rope 116. At the same time, the auxiliary roller 113 is used to limit the movement angle and direction of the pull rope 116 to prevent the pull rope 116 from tilting when it moves. The weight of the portable water pump 12 and the protective sleeve 13 is used to make the pull rope 116 move vertically downward. The portable water pump 12 will not tilt or collapse when it touches the bottom due to the push of the water source or external force.

[0036] Working principle: The rope coiler 115 lowers the pull rope 116, allowing the portable water pump 12 to descend vertically. The protective sleeve 13 on the outer surface of the portable water pump 12 increases the weight at the bottom of the portable water pump 12, enabling the portable water pump 12 to move vertically downward. The protective sleeve 13 lowers the center of gravity of the portable water pump 12, preventing it from tilting or collapsing when it touches the bottom due to the push of the water source or external force.

[0037] When the portable water pump 12 and the protective sleeve 13 descend, the mud-adhesive plates 134 on one end of the multiple swing rods 133 are pushed upward by the reverse force of the water source, causing the swing rods 133 to swing upward. The other end of the swing rods 133 presses down on the push sleeve 137, pushing the slide rod 135 to the lowest position. When the protective sleeve 13 contacts the bottom of the mud, the contact area with the bottom of the mud is increased by the contact impact plate 136 on the bottom surface of the slide rod 135, so that the contact impact plate 136 will not directly insert into the mud, thereby reducing the possibility that the water inlet of the portable water pump 12 will directly contact the mud and cause blockage.

[0038] Under the downward pressure of the portable water pump 12 and the protective sleeve 13, the impact plate 136 will push the slide rod 135 and the push sleeve 137 in the opposite direction, and the push sleeve 137 will lift and squeeze one end of the swing rod 133, and the mud-adhesive plate 134 on the other end of the swing rod 133 will adhere to the surface of the mud bottom layer. The multiple sets of swing rods 133 increase the contact range between the protective sleeve 13 and the mud surface, and the lower center of gravity of the protective sleeve 13 prevents the portable water pump 12 and the protective sleeve 13 from tilting, shaking and collapsing.

[0039] When the portable water pump 12 is pumping water, the external water source will be directly pumped into the interior of the protective sleeve 13 through the water inlet 131 on the surface of the protective sleeve 13. The narrow gap of the water inlet 131 can effectively reduce the possibility of external solid impurities, branches, plastic bags and small fish directly entering the interior of the protective sleeve 13 and clogging the water inlet of the portable water pump 12.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
