Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a floating water pump head for a water pump. Background Art

[0002] A water pump is a machine that transports liquids or pressurizes liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals.

[0003] Existing water pumps generally directly place the pumping pipe into the water when pumping water. However, when the bottom of the water is silty or uneven, it is often difficult to pump out the water cleanly, and even blockage may occur, damaging the water pump. The pumping pipe needs to be repeatedly placed, which is time-consuming and labor-intensive. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0005] To this end, the technical solution adopted in this utility model is:

[0007] In a preferred example, the utility model can be further configured as follows: a light strip is installed on the top of the floating body.

[0008] In a preferred example, the utility model can be further configured as follows: a clamping groove is opened in the float, and a clamping ring fixed to the outside of the sleeve is clamped in the clamping groove.

[0009] In a preferred example, the utility model can be further configured as follows: a filter plate is provided at the bottom of the sleeve, and a cone weight is fixed at the bottom of the filter plate.

[0010] In a preferred example, the present invention can be further configured as follows: a mud-proof plate is fixed to the outer side of the cone weight.

[0011] In a preferred example, the utility model can be further configured as follows: the lower end of the gear cylinder is connected to a bevel gear set, the outer side of the bevel gear set is connected to an electric telescopic rod, and the outer end of the electric telescopic rod is connected to a fan blade located outside the float.

[0012] The above technical solution of the utility model has the following beneficial technical effects:

[0013] 1. The utility model can utilize a floating body to make the water inlet of the water pumping pipe float on the water surface for pumping through a pumping assembly, thereby avoiding the problem of excessive sediment or unevenness on the bottom of the water. At the same time, the servo motor can drive the plane gear transmission to move the counterweight to the opposite side of the water pumping pipe, thereby ensuring that the floating body will not tilt under the downward pressure on one side of the water pumping pipe, thereby ensuring the stability and reliability of floating pumping.

[0014] 2. The utility model uses a pumping assembly. When the water is pumped to a shallow depth, the sleeve will automatically move upward to ensure continuous pumping. When the filter plate is blocked, the sleeve will passively move upward to obtain a blockage signal. The utility model can choose to adjust the pumping position or spray water in reverse to clean the blockage of the filter plate, which is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0021] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0022] A floating pumping head for a water pump provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings.

[0023] Combination Figure 1-2 As shown, the utility model provides a floating pump head for a water pump, comprising: a body assembly 100 and a pumping assembly 200 ; wherein the body assembly 100 comprises a pump body 110 and a pumping pipe 120 connected to the pump body 110 .

[0024] The pumping assembly 200 is connected to the pumping pipe 120, and the pumping assembly 200 includes a float 210 connected to the end of the pumping pipe 120, a sleeve 220 movably mounted in the middle of the float 210, a mounting cavity 230 opened in the float 210, a flat gear 240 assembled in the mounting cavity 230, a counterweight 250 fixed on the side of the flat gear 240, a gear cylinder 260 meshingly connected to the side of the flat gear 240, and a servo motor connected to the upper end of the gear cylinder 260. The servo motor 270 and the electronic level 280 embedded in the float 210 can use the float 210 through the pumping assembly 200 to make the water inlet of the pumping pipe 120 float on the water surface for pumping water, thereby avoiding the problem of excessive mud or unevenness on the bottom of the water. At the same time, the servo motor 270 can drive the plane gear 240 to transmit and move the counterweight block 250 to the opposite side of the pumping pipe 120, thereby ensuring that the float 210 will not tilt under the downward pressure on one side of the pumping pipe 120, thereby ensuring the stability and reliability of floating pumping.

[0025] Specifically, a light strip 211 is installed on the top of the floating body 210 to provide a warning or guidance function, thereby facilitating night operations.

[0026] Furthermore, a slot 212 is provided in the float 210 , and a clamping ring 213 fixed to the outside of the sleeve 220 is clamped in the slot 212 , so that the sleeve 220 can move up and down in the float 210 , thereby improving practicality.

[0027] On the other hand, a filter plate 221 is provided at the bottom of the sleeve 220, and a conical weight 222 is fixed to the bottom of the filter plate 221. When the water is pumped to a shallower depth, the sleeve 220 will automatically move upward to ensure continuous pumping. When the filter plate 221 is blocked, the sleeve 220 will passively move upward to obtain a blockage signal. You can choose to adjust the pumping position or spray water in reverse to clear the blockage of the filter plate 221, which is highly practical.

[0028] It should be noted that a mud-proof plate 223 is fixed to the outer side of the conical weight block 222 , which can press down part of the mud when the sleeve 220 touches the bottom, so as to prevent the mud from directly blocking the filter plate 221 .

[0029] On the other hand, the lower end of the gear cylinder 260 is connected to a bevel gear set 261, the outer side of the bevel gear set 261 is connected to an electric telescopic rod 262, and the outer end of the electric telescopic rod 262 is connected to a fan blade 263 located on the outside of the float 210. The extension and retraction of the electric telescopic rod 262 can be used to control the on and off of the bevel gear set 261. When disconnected, the fan blade 263 does not work and the float 210 is stationary. When the float 210 needs to move, the fan blade 263 is driven to rotate by the servo motor 270, and the balance of the float 210 can be readjusted after disconnection.

[0030] The working principle and use process of the utility model are as follows: first, the float 210 is placed in the water to be pumped, and the float 210 will tilt toward one side of the pumping pipe 120. At this time, the servo motor 270 drives the plane gear 240 to transmit, and moves the counterweight block 250 to the opposite side of the pumping pipe 120, so as to ensure the balance of the float 210 and pump water. When the water is pumped to a shallower level, the sleeve 220 will be pushed upward to ensure the continuous pumping. When the filter plate 221 is blocked, the sleeve 220 will be moved upward by suction, so that the operator can remotely obtain the blockage signal, and then choose to adjust the pumping position, or spray water in reverse to clean the blockage of the filter plate 221. This operation is sufficient.

[0031] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
