Description

Technical Field

[0001] This utility model relates to the field of water pump technology, and in particular to a floating water pump with a novel connection method. Background Technology

[0002] A floating water pump is a device specifically designed for pumping water from natural water bodies such as lakes and reservoirs. It uses the rotation of an impeller to generate centrifugal force or axial thrust to lift water to the target area. Its core principle is: a motor drives the impeller to rotate, giving the liquid kinetic and pressure energy, thus enabling continuous transport.

[0003] In conventional floating water pumps, the drive motor and impeller are connected by connecting sleeves at both ends of the connecting shaft, which is complex and difficult to install and maintain. Furthermore, with increased usage and years, the oil seal between the connecting shaft and the pump housing deteriorates, causing small water meters inside the pump to be forced out of the oil seal due to pressure. This damages the drive motor at the top, reduces its lifespan, and is detrimental to the long-term use of the water pump. Utility Model Content

[0004] In view of this, the present invention proposes a floating water pump with a novel connection method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel floating water pump with a specific connection method includes a pump housing, an impeller disposed within the pump housing, a drive motor disposed at the upper end of the pump housing, and a connecting shaft. The lower end of the connecting shaft is connected to the impeller, and the upper end of the connecting shaft has a connecting through hole and a clamping groove, the clamping groove communicating with the connecting through hole. The output shaft of the drive motor is fitted into the connecting through hole, and a clamping member is disposed outside the connecting shaft. The clamping member achieves fixed installation between the output shaft of the drive motor and the connecting shaft by reducing the spacing between the clamping grooves.

[0007] As a further improvement to the above technical solution:

[0008] As an optimized version of the above technical solution, the clamping member is composed of two arc-shaped clamps, and the two ends of the two arc-shaped clamps are connected to nuts by fixing bolts.

[0009] As an optimized version of the above technical solution, a water-blocking block is sleeved on the connecting shaft, and the water-blocking block is located between the impeller and the clamping member.

[0010] As an optimized solution to the above technical solution, a motor base is provided between the water pump housing and the drive motor. The motor base includes a water pump connecting plate fixedly connected to the water pump housing, a motor connecting plate fixedly connected to the drive motor, and a plurality of support plates arranged in a circumferential array between the water pump connecting plate and the motor connecting plate. An oil seal cover plate is provided on the water pump connecting plate, and the connecting shaft passes through the middle of the oil seal cover plate.

[0011] As an optimized solution to the above technical solution, a buoyancy component is provided on the outside of the support plate, which is used to float the entire floating water pump on the water surface.

[0012] As an optimized version of the above technical solution, the buoyancy component includes a buoyancy connecting plate connected to the support plate, a connecting rod disposed on the buoyancy connecting plate, and a buoyancy ball disposed at the other end of the connecting rod.

[0013] As an optimized version of the above technical solution, a garbage filter screen is provided at the water inlet at the lower end of the water pump housing, and a number of water passages are provided on the garbage filter screen.

[0014] As an optimized solution to the above technical solution, a rain shield is provided at the upper end of the drive motor to block rainwater.

[0015] As an optimized version of the above technical solution, the rain shield includes a plurality of support rods connected to the upper end of the drive motor and a rain shield disposed on the upper end of the support rods, wherein the rain shield is coaxially distributed with the upper end of the drive motor.

[0016] As an optimized solution to the above technical solution, a plug is provided at the connection between the connecting through hole and the impeller.

[0017] Compared with existing technologies, the beneficial effects of this utility model are:

[0018] 1. The floating water pump provided by this utility model changes the connection method between the drive motor and the impeller. By adopting a direct connection between the connecting shaft and the impeller, the contact area between the connecting shaft and the impeller is increased, thereby increasing the stability of the impeller during high-speed rotation and reducing oscillation. The drive motor output shaft is inserted into the connecting through hole at the upper end of the connecting shaft, and the clamping members reduce the spacing of the clamping grooves, thus reducing the diameter of the connecting through hole and clamping the output shaft. As a result, the entire connection scheme is simpler, and installation, debugging, and maintenance are more convenient.

[0019] 2. A water baffle is fitted on the upper end of the connecting shaft. Even if the oil seal is damaged, the water will be guided to the outside by the water baffle due to the upward pressure. This prevents the water from impacting the drive motor due to pressure, which could damage the drive motor. At the same time, the water baffle rotates synchronously with the connecting shaft, which also prevents the impacting water from impacting the same position of the water baffle and causing damage. This increases the service life of the water pump and reduces the number of maintenance times.

[0020] 3. A rain cover is installed on the drive motor, which is mounted on a support rod. This prevents rainwater from damaging the drive motor's circuitry when the water pump is used in rainy weather, without affecting the heat dissipation of the drive motor.

[0021] 4. A debris filter screen is installed at the lower end of the water pump casing to prevent large debris or large fish from entering the impeller through the water inlet of the water pump casing and causing damage to the impeller.

[0022] 5. Equipped with a buoyancy component, the entire unit can float on the water surface, allowing extraction to be carried out at the water surface. Compared to extraction directly from the bottom, this reduces the impact of sediment on the water pump and avoids sediment loss. Attached Figure Description

In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] As attached Figure 1 To be continued Figure 5 As shown, this technical solution includes three parts: the main body of the water pump, the connecting part, the drive motor, and the connecting shaft.

[0033] I. Main body of the water pump

[0034] The main body of the water pump is mainly composed of the water pump housing 1. The water pump housing 1 is mainly welded together by the middle part of the surrounding plate and the upper and lower end plates. The front end of the water pump housing 1 has a water outlet, the middle part of the lower end plate has a water inlet, the upper end plate has an opening, and the impeller 2 is installed inside.

[0035] To prevent large debris or large fish from flowing into the pump body through the inlet during subsequent pumping, a debris filter 17 is fixedly installed on the lower end plate, thus separating debris and fish during pumping.

[0036] II. Connection Part

[0037] The connecting part is mainly the motor base 9. The lower end of the motor base 9 is the water pump connecting plate 10. The size of the water pump connection is larger than the size of the upper end, which is used to cover the upper opening and to seal it by means of welding the edge, using sealing rings, etc. At the same time, a through hole is provided in the middle of the water pump connecting plate 10 for the connecting shaft 4 to pass through. At the same time, an oil seal cover plate 13 is provided around the through hole for sealing the middle.

[0038] The upper end of the motor mount 9 is a motor connecting plate 11, which is used to connect the motor;

[0039] Multiple support plates 12 arranged in a circular array are used to connect the motor connecting plate 11 and the water pump connecting plate 10.

[0040] III. Drive Motor (3 parts)

[0041] The drive motor 3 is fixedly mounted on the motor connecting plate 11 at the upper end of the motor base 9 by bolts;

[0042] As can be seen from the attached drawings, the heat dissipation air intake of the drive motor 3 is located at the top. In order to prevent rain from affecting the motor, a rain cover 19 is provided at the top of the drive motor 3 in this technical solution. It is coaxially distributed with the top of the drive motor 3. Considering the impact on the heat dissipation air intake, the drive motor 3 and the rain cover 19 are supported and connected by several support rods 18.

[0043] IV. Connecting Shaft (4 parts)

[0044] The lower end of the connecting shaft 4 passes through the through hole in the middle of the water pump connecting plate 10 and is directly connected to the impeller 2 by bolts. Compared with the connecting sleeve connection method, the connecting shaft 4 is directly connected to the impeller 2, which reduces the cost and has a larger contact area, which can reduce the shaking during rotation and make the operation more stable.

[0045] There is a connecting through hole 5 in the middle of the upper end of the connecting shaft 4. The diameter of the connecting through hole 5 is slightly larger than the diameter of the output shaft of the drive motor 3. Therefore, the output shaft of the drive motor 3 is inserted into the connecting through hole 5. In order to prevent water from rushing into the connecting shaft 4 from the lower end of the connecting through hole 5 and thus damaging the output shaft of the drive motor 3, a plug 20 is used to block it before the lower end of the connecting through hole 5 is connected to the impeller 2. In order to achieve the blocking effect, the size of the plug 20 should be larger than the diameter of the connecting through hole 5, and it should also have the ability to deform. Therefore, nylon plugs or rubber plugs or similar materials can be used.

[0046] To fix the output shaft of the drive motor 3 to the connecting through hole 5, clamping grooves 6 are machined on the connecting shafts 4 on both sides of the connecting through hole 5. At the same time, two arc-shaped clamps 7 are used to clamp the connecting shafts 4 on the outside. The distance between the two arc-shaped clamps 7 is adjusted by bolts and nuts at both ends of the arc-shaped clamps 7, so that the distance between the clamping grooves 6 is reduced, thereby reducing the inner diameter of the connecting through hole 5, achieving the purpose of clamping the output shaft. Therefore, the connection between the drive motor 3 and the connecting shaft 4 is reduced, the structure is simpler, the installation is easier, and the subsequent maintenance cost is lower. At the same time, through experiments, this connection method is more compact and has a longer service life. In addition, it is a similar replacement for other clamping tools that reduce the distance to achieve the purpose of clamping.

[0047] Meanwhile, to prevent the oil seal from breaking and aging due to the number of uses and service life, which could cause water to spray out from the damaged part of the pump body due to pressure and damage to the drive motor 3, a water baffle 8 is also installed on the connecting shaft 4. The water baffle 8 rotates synchronously with the connecting shaft 4, which can guide the sprayed water to the surrounding area and prevent the water from continuously spraying at the same position on the water baffle 8. This increases the service life of the drive motor 3 and the water baffle 8. Therefore, the shape of the water baffle 8 can be round, square or irregular.

[0048] To avoid the situation where the water pump in the above-mentioned technical solution sinks to the bottom of the water and causes silt loss or damage and jamming of the water pump, this technical solution also provides a buoyancy component that allows the water pump to float on the horizontal surface for pumping. The specific structure is as follows: a buoyancy connecting plate 14 is connected to the support plate 12 by bolts. A connecting rod 15 is provided on the buoyancy connecting plate 14, and a buoyancy ball 16 is provided at the other end of the connecting rod 15. In order to ensure that the water inlet of the water pump body is underwater but most of it is on the water surface, as shown in the attached figure, the connecting rod 15 is at a certain angle to the horizontal plane and tilted upward. Since there are multiple support plates 12, there are also multiple buoyancy balls 16. For example, there are three in the attached figure, which are distributed in a circular array. Thus, the whole is stable in the water and no excessive tilting is observed.

[0049] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
