Description

Technical Field

[0001] This invention relates to the field of electric water pump technology, specifically a high-flow-rate electric water pump. Background Technology

[0002] Electric water pumps are fluid transport devices driven by electricity. The core of them relies on the motor to drive the impeller to rotate, and the liquid is sucked in and discharged through centrifugal force. Some brushless models also have the ability to handle both air and water.

[0003] Currently, electric water pumps used in outdoor river water extraction operations have certain shortcomings in actual use. For the safety of pumping operations, outdoor electric water pumps need to be fixed on the riverbank and connected to the pump casing inlet section via an external pipe until the external pipe is submerged in the river water. However, after the external pipe is placed on the ground, the section of the pipe extending into the river water is easily disturbed by silt and sediment from the riverbed. In severe cases, silt and sediment may enter the pipe or pump, which will affect the actual pumping flow rate. Moreover, as the water level drops, once the inlet end of the external pipe is exposed above the liquid surface, the extraction of air-mixed solutions will further cause cavitation problems in the pipe and pump, which will damage the pump.

[0004] In view of this, the present invention designs a high-flow electric water pump to solve the above problems. Summary of the Invention

The support mechanism provides an effective support for the river distance adjustment mechanism and provides an adjustment platform for the tilt angle of the diversion mechanism. The river distance adjustment mechanism supports the pumping mechanism, facilitating lateral distance control along the water surface. The pumping mechanism provides support for the diversion mechanism and works in conjunction with it to extract water from the inner side of the riverbank at high flow rates.

[0010] In a preferred embodiment, the present invention can be further configured such that: a horizontally placed slide rail is inserted into the external pad and the internal pad, a slide rail is provided at the bottom of the slide rail, and two symmetrically distributed reinforcing beams are provided on both sides of the slide rail, and the two reinforcing beams are fixedly installed in the external pad and the internal pad by a plurality of third bolts.

[0011] In a preferred embodiment, the present invention can be further configured as follows: the pumping mechanism includes a slide table disposed on the top of the slide rail and two reinforcing beams, a slider is fixedly installed at the bottom of the slide table, and two pulleys are movably installed inside the slider, and the slider and the two pulleys are movably installed inside the slide rail; A motor and a water pump are installed on the top of the slide, and multiple combination bolts are installed on the inlet pipe section of the water pump.

[0012] In a preferred embodiment, the present invention can be further configured as follows: a truss is fixedly installed on the slide, and an arc-shaped support is installed on the truss. A first insert rod is inserted into the arc-shaped support. A force arm is movably installed on the first insert rod. A groove is formed in the force arm, and a second insert rod is inserted into the middle of the groove. A third insert rod is inserted into the other end of the force arm, and a clamp is movably installed on the outside of the third insert rod.

[0013] In a preferred embodiment, the present invention may be further configured as follows: the drainage mechanism includes a transfer pipe fixed to the inlet pipe end of the water pump by a plurality of combined bolts, a flexible metal pipe fixedly installed at the other end of the transfer pipe, a plurality of fourth bolts inserted into the pipe section at the other end of the flexible metal pipe, and a vertical pipe snapped into the pipe section of the flexible metal pipe away from the transfer pipe, and a filter cover fixedly installed at the bottom end of the vertical pipe.

[0014] In a preferred embodiment, the present invention can be further configured such that: the outer wall of the vertical tube has a plurality of evenly distributed holes and grooves, and a filter screen is fixedly installed in the holes and grooves; two symmetrically distributed elliptical recesses are provided on both sides of the top of the vertical tube, and two fifth bolts are inserted into the elliptical recesses.

[0015] In a preferred embodiment, the present invention can be further configured as follows: a core tube is inserted into the bottom of the inner cavity of the vertical tube, and the core tube is fixed to the top of the inner cavity of the vertical tube by a fifth bolt; a corrugated pipe is fixedly installed at the bottom end of the core tube; a float is fixedly installed at the other end of the corrugated pipe; a float pad is inserted into the float; a guide pipe is installed in the screw hole at the bottom of the float; and multiple evenly distributed fan-shaped holes are opened at the bottom end of the guide pipe.

[0016] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows: 1. This invention provides a supporting mechanism at the bottom of the pumping mechanism, which is used to fix the horizontally positioned pumping mechanism to the riverbank until the pump is pushed horizontally and delivered to the inner side of the riverbank and directly above the water surface. At this time, the diversion mechanism assembled on the pumping mechanism can be adapted and adjusted according to the water level on the inner side of the riverbank, and the float and floating pad located in the vertical pipe can be adapted and adjusted in accordance with the drop in water level. This enables high-flow pumping operation without contact between the pipeline inlet section and the riverbed.

[0017] 2. In this invention, when the rotating shaft is manually rotated until the winding roller drives the cable to wind and release freely, the second insert connected to the exposed section of the cable will cause the power arm and clamp to tilt longitudinally. The vertical pipe and flexible metal pipe will tilt and adjust around the transfer pipe. Finally, the vertical pipe and filter cover can be efficiently adjusted for unknown water areas, making it easy to maintain a safe distance between the diversion mechanism and the riverbed silt and sediment, thus enabling the safe use of the device in unknown water areas.

[0018] 3. This invention involves opening multiple evenly distributed holes and grooves on the outer wall of a vertical pipe, fixing filter screens in the corresponding holes and grooves, and using corrugated pipes to fix and connect the floats. As the water level in the river drops, the river water can quickly flow into the inner cavity of the vertical pipe through the corresponding holes and grooves on the outer wall. Finally, the floats and pads can rise and fall smoothly along the inner cavity of the vertical pipe. This not only improves the automatic removal of pollutants in the river water, but also avoids the drawbacks of air entering the pipe and causing cavitation inside the pump casing.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0022] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0023] The following describes, with reference to the accompanying drawings, some embodiments of a high-flow electric water pump provided by the present invention.

[0024] Example 1: Combination Figures 1 to 12 As shown, the present invention provides a high-flow-rate electric water pump, comprising a support mechanism 100 installed on a riverbank, a river distance adjustment mechanism 200 disposed on the support mechanism 100, a pumping mechanism 300 installed on the river distance adjustment mechanism 200, and a diversion mechanism 400 installed on the pumping mechanism 300. The support mechanism 100 provides an effective support carrier for the river distance adjustment mechanism 200 and provides an adjustment platform for the tilt angle of the diversion mechanism 400. The river distance adjustment mechanism 200 supports the pumping mechanism 300, facilitating the control of the pumping mechanism 300 to adjust the lateral distance along the water surface. The pumping mechanism 300 provides support for the diversion mechanism 400 and cooperates with the diversion mechanism 400 to extract water from the inner side of the riverbank at a high flow rate. The diversion mechanism 400 is used to safely and efficiently extract river water and prevent riverbank silt and sewage from entering the pipes and pump casing.

[0025] The supporting mechanism 100 includes a reinforced base 110. A first support plate 1101 and a second support plate 1102 are symmetrically distributed and fixedly installed on the outer wall of the reinforced base 110. A rotating shaft 120 is movably installed inside the first support plate 1101 and the second support plate 1102. A take-up roller 130 is fixedly installed on the outside of the rotating shaft 120. A first bolt 1103 that is pressed against the rotating shaft 120 is installed on the inner thread of the tube end of the outer end of the first support plate 1101. A cable 140 is wound on the take-up roller 130.

[0026] Preferably, the front of the reinforcing base 110 has an L-shaped structure, and multiple pre-installed holes are opened in the plate end at the bottom of the reinforcing base 110. The stability of the reinforcing base 110 on the riverbank can be achieved by fixing pins. The rotating shaft 120 passes through the rod segment outside the second support plate 1102 and is fixedly installed with a rotating wheel. The first bolt 1103 is used to control the stability of the rotating shaft 120 after rotation in real time.

[0027] The river distance adjustment mechanism 200 includes an external pad 210 and an internal pad 220 installed in the reinforced base 110. The bottom of both the external pad 210 and the internal pad 220 is provided with a protruding end. A bearing 260 is installed in the hole of the protruding end. There are two bearings 260. A horizontally placed reciprocating screw 250 is installed in the two bearings 260. Two support legs 2201 are fixedly installed at the bottom of the internal pad 220. A pressure wheel 2202 is movably installed in the two support legs 2201. The tensioned cable 140 is adapted to bear pressure on the pressure wheel 2202. Both the external pad 210 and the internal pad 220 are fitted with two second bolts 270 and four third bolts 280. The external pad 210 and the internal pad 220 are connected to a horizontally placed slide rail 240. The bottom of the slide rail 240 is provided with a slide track 2401. Two symmetrically distributed reinforcing beams 230 are provided on both sides of the slide rail 240. The two reinforcing beams 230 are fixedly installed in the external pad 210 and the internal pad 220 by multiple third bolts 280.

[0028] Preferably, the external pad 210 and the internal pad 220 are used to clamp and fix the slide rail 240 and the two reinforcing beams 230, further ensuring the structural strength of the slide rail 240 and the two reinforcing beams 230 after horizontal placement after assembly, thereby providing an effective support platform for the lateral sliding of the pumping mechanism 300, which facilitates the control of the pumping mechanism 300 to move freely along the inner side of the riverbank. Among them, the cross-section of the reinforcing beam 230 is I-shaped, and the gap between the two reinforcing beams 230 extending into the inner side of the river embankment is used to provide anti-tilt protection for the diversion mechanism 400, further improving the safety of the diversion mechanism 400 when used in flowing river water.

[0029] The pumping mechanism 300 includes a slide table 310 disposed on top of the slide rail 240 and two reinforcing beams 230. A slider 3101 is fixedly installed at the bottom of the slide table 310, and two pulleys 3102 are movably installed inside the slider 3101. The slider 3101 and the two pulleys 3102 are movably installed inside the slide rail 240. The top of the slide 310 is equipped with a motor 320 and a water pump 330, and multiple combination bolts 3301 are installed on the inlet pipe section of the water pump 330.

[0030] Preferably, both the slide table 310 and the motor 320 are fixed to the studs on the top of the slide table 310 by nuts, and the main shaft of the motor 320 extends into the inner cavity of the motor 320, while an impeller is fixedly installed on the rod section of the motor 320 that extends into the water pump 330, which facilitates efficient pumping of river water. Among them, the arc-shaped support 3401 has a quarter-circle arc structure, and the exposed end of the cable 140 is fixedly installed on the second insert rod 3502. The cable 140, whether loose or tense, can control the diversion mechanism 400 to adjust the inclination angle along the river.

[0031] Example 2: Combination Figure 3 and Figure 10 As shown, based on embodiment 1, a truss 340 is fixedly installed on the slide table 310, and an arc-shaped support 3401 is installed on the truss 340. A first insert rod 3402 is inserted into the arc-shaped support 3401. A force arm 350 is movably installed on the first insert rod 3402. A groove 3501 is opened in the force arm 350, and a second insert rod 3502 is inserted into the middle of the groove 3501. A third insert rod 3503 is inserted into the other end of the force arm 350, and a clamp 360 is movably installed on the outside of the third insert rod 3503. The drainage mechanism 400 includes a transfer pipe 410 fixed to the inlet pipe end of the water pump 330 by multiple combination bolts 3301. A flexible metal pipe 420 is fixedly installed at the other end of the transfer pipe 410. Multiple fourth bolts 4201 are inserted into the pipe section at the other end of the flexible metal pipe 420. A vertical pipe 430 is snapped into the pipe section of the flexible metal pipe 420 away from the transfer pipe 410. A filter cover 440 is fixedly installed at the bottom end of the vertical pipe 430.

[0032] Preferably, two posts are fixedly installed on the back of the clamp 360, and the third insert rod 3503 is installed inside the two posts. The bottom end of the lever arm 350 is movably installed on the outside of the third insert rod 3503. When the rotating shaft 120 rotates and drives the take-up roller 130, the cable 140 freely retracts along the outside of the take-up roller 130, which controls the second insert rod 3502 and the lever arm 350 to freely adjust around the first insert rod 3402 as the axis. The other end of the lever arm 350 controls the clamp 360 to lift or lower accordingly, which makes it easy to control the diversion mechanism 400 to adapt to the unknown water area for use.

[0033] Example 3: Combination Figures 10 to 12 As shown, in the above embodiment, the outer wall of the vertical tube 430 is provided with a plurality of evenly distributed holes and grooves 4301, and a filter screen 4302 is fixedly installed in the holes and grooves 4301. Two symmetrically distributed elliptical concave holes are provided on both sides of the top of the vertical tube 430, and two fifth bolts 4303 are inserted into the elliptical concave holes. A core tube 450 is inserted into the bottom of the inner cavity of the vertical tube 430, and the core tube 450 is fixed to the top of the inner cavity of the vertical tube 430 by the fifth bolt 4303. A corrugated tube 460 is fixedly installed at the bottom end of the core tube 450, and a float 470 is fixedly installed at the other end of the corrugated tube 460. A float pad 4701 is inserted into the float 470, and a guide tube 480 is installed in the screw hole at the bottom of the float 470. Multiple evenly distributed fan-shaped holes 4801 are opened at the bottom end of the guide tube 480.

[0034] Preferably, the vertical pipe 430 has a T-shaped structure, and a filter screen is fixedly installed inside the filter cover 440. Multiple holes and slots 4301 opened along the outer wall of the vertical pipe 430 can be adapted to the drop in water level on the inner side of the riverbank, which facilitates the efficient injection of river water. The guide pipe 480 has multiple evenly distributed fan-shaped slots on its wall. After the river water flows into the inner cavity of the vertical pipe 430 through the slots 4301, it can be quickly transferred through the fan-shaped slots and the float 470. The float 4701 provides effective suspension support for the guide pipe 480, and can move the guide pipe 480 up and down in conjunction with the rise and fall of the water level, so as to facilitate the high-speed transfer of river water.

[0035] The working principle and usage process of this invention are as follows: The bearing mechanism 100 is placed horizontally on the top of the river embankment until the bottom plate of the reinforcing base 110 is stably placed on the top of the river embankment. Then, the horizontally placed bearing mechanism 100 is pressed onto the top of the river embankment using pins or fixing bolts until the bearing mechanism 100 is in a stable state. Then, the diversion mechanism 400 is installed on the inlet pipe of the water pump 330 using multiple combination bolts 3301 until the diversion mechanism 400 is located in the gap between the two reinforcing beams 230. Next, based on the water conditions within the riverbank, the outer wheel of the reciprocating screw 250 is manually rotated until the horizontally placed reciprocating screw 250 rotates along the two bearings 260. Finally, the slider 3101 and the two pulleys 3102 will move smoothly horizontally along the slide rail 240 and the slide channel 2401. Finally, the entire pumping mechanism 300 will be pushed horizontally along the top of the slide rail 240 and the two reinforcing beams 230 towards the water source within the riverbank until the diversion mechanism 400 sinks down with the water source. When the water source inside the riverbank is abundant, in order to increase the flow rate of the solution in the inner cavity of the water pump 330, the user can reverse the first bolt 1103 until the shaft 120 is in a relaxed state. Then, rotate the shaft 120 and drive the take-up roller 130 to release the cable 140. The cable 140 in the relaxed state loses the traction force on the lever arm 350 and the second insert rod 3502. As a result, the diversion mechanism 400 will be in a vertical state with the water surface, and the guide pipe 480, float 470 and float pad 4701 will float longitudinally along the inner cavity of the vertical pipe 430. At this time, the guide pipe 480 will be completely submerged below the liquid surface. This process can avoid the water entering the pump 330 from being mixed with air, and at the same time avoid the risk of cavitation in the pipeline and pump casing. Meanwhile, as the water level inside the riverbank drops, the multiple slots 4301 on the outer wall of the vertical pipe 430 can work with the float 470 and the floating pad 4701 to regulate the real-time intake of water, ensuring a constant water intake during the drop in water level. The floating water intake can automatically remove suspended solids in the water source with the help of the vertical pipe 430, multiple filters 4302 and a filter cover 440, avoiding the drawback of water intake obstruction caused by the blockage of suspended solids in traditional fixed water inlets. When the riverbed is unclear and contains a large amount of silt, in order to improve the flow rate of the transferred solution, the user can rotate the shaft 120 until the winding roller 130 winds up the cable 140. The tensioned cable 140 will be pressured by the bearing wheel 2202 and will pull the arm 350 and the second insert 3502 to tilt upwards around the first insert 3402 until the vertical pipe 430 and the flexible metal pipe 420 are tilted inside the riverbank. This makes it easy to keep the multiple holes and grooves 4301 on the surface of the vertical pipe 430 and a filter cover 440 from contacting the silt on the riverbed. This allows for safe use in unknown waters and further reduces the problem of silt and dirt entering the pipe and pump casing, which would cause a decrease in pumping flow.

[0036] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
