Detailed implementation manners

[0032] Embodiment 1

[0033] As Figures 1-6 shown in the figure, a filter protection device for a fish tank water pump includes a protective cover 1. The protective cover 1 includes a receiving chamber 101 and an annular plate 102. A plurality of filter holes 103 are provided through the receiving chamber 101. A plurality of adjusting rods 2 are threadedly connected to the annular plate 102. The protective cover 1 is detachably arranged on the bottom shell 5 of the water pump. The protective cover 1 is used to protect the motor on one side of the bottom shell 5 of the water pump. When the motor on one side of the bottom shell 5 of the water pump is working, there will be a large negative pressure. Therefore, when the protective cover 1 is placed on the bottom shell 5 of the water pump, the protective cover 1 can maintain a stable state under the action of the negative pressure. The water pump in the fish tank needs to work all day and all the time. During operation, sundries from the fish tank water quality will be adsorbed on the protective cover 1, and at the same time, the risk of smaller fry being sucked into the water pump is avoided. If the aperture of the filter hole 103 is too large, sundries will be sucked into the water pump. If the aperture of the filter hole 103 is too small, sundries will be covered and blocked on the protective cover 1, resulting in the inability of the water flow to circulate under the action of the water pump. By setting the adjusting rods 2 on the annular plate 102, the gap between the protective cover 1 and the bottom shell 5 of the water pump can be adjusted, thus ensuring that the water can circulate well through the water pump and avoiding the above problems. And because the installation of horizontal water pumps and vertical water pumps is different, the operation and use are facilitated by the adjusting rods 2. When cleaning is required, the protective cover 1 can be directly removed. After cleaning, it is placed back on one side of the bottom shell 5 of the water pump. The operation is simple, thus solving the problem of having to completely remove the water pump for disassembly and cleaning.

[0034] In a preferred solution, a groove 501 is provided in the middle of the bottom shell 5 of the water pump. The receiving chamber 101 is located in the groove 501. A water flow hole 502 is provided in the middle of the groove 501. A guide shaft 3 is detachably provided in the middle of the receiving chamber 101. The guide shaft 3 passes through the water flow hole 502. The guide shaft 3 can play a positioning role during rapid installation and can better introduce the water flow into the interior of the water pump to complete the circulation of the water flow.

[0035] In a preferred solution, a plurality of partition plates 302 are provided on the outer side of the guide shaft 3. An overflow channel 303 is formed between two adjacent partition plates 302. The lower sides of the plurality of partition plates 302 are connected by a limiting sleeve 304. The plurality of partition plates 302 cooperate with the water flow hole 502 to form a plurality of separate spaces, thus ensuring the stable diversion of the water flow and being beneficial to increasing the speed of the water flow. The limiting sleeve 304 further restricts the flow cross-section of the water flow, increasing the pressure and speed, and making the response state of the water flow better.

[0036] In a preferred embodiment, a through hole 105 is provided through the middle of the accommodation bin 101. A first mounting hole 301 is provided at the top of the diversion shaft 3. The locking pin 4 is inserted into the through hole 105, and the locking pin 4 is threadedly connected to the first mounting hole 301. The overall production is convenient and the installation is simple. The diversion shaft 3 and the protective cover 1 can be fully disassembled as needed. When maintenance and cleaning are required, the cleaning effect is better.

[0037] In a preferred embodiment, a plurality of fixing holes 503 are provided on the water pump bottom shell 5. Screws 7 are provided in the fixing holes 503. One side of the adjusting rod 2 is located in the fixing holes 503, and the bottom of the adjusting rod 2 abuts against the top of the screw 7. Regardless of the depth of the groove 501, the cooperation of the fixing holes 503 and the screws 7 can further ensure high precision and good effect in the installation of the protective cover 1, thereby improving the impact resistance of the protective cover 1 and making the use effect more stable.

[0038] In a preferred embodiment, the cross-sectional width of the partition 302 becomes smaller and smaller in the direction away from the limit sleeve 304 along the central axis of the diversion shaft 3. By reducing the area of the flow-through cross-section, the speed and pressure of the water flow passing through the diversion shaft 3 are further effectively and stably increased, thereby ensuring the high efficiency of the water flow circulation.

[0039] Embodiment 2

The rotating shaft 602 is inserted into the support sleeve 601, and a plurality of blades 603 are provided at the bottom of the rotating shaft 602. When the size of the water flow hole 502 is large, there is enough space to install the flow-pushing unit 6. After passing through the diversion shaft 3, the blades 603 are pushed, so as to better play the role of diffusing the water flow and assist the water pump in stable drainage operation.

[0041] In a preferred embodiment, a second mounting hole 305 is provided at the lower part of the diversion shaft 3. The support sleeve 601 is detachably connected to the second mounting hole 305. A disc 605 is provided at the top of the rotating shaft 602. A plurality of blades 603 are connected to the bottom of the rotating shaft 602 through a mounting sleeve 604. The installation is more convenient. Select an appropriate number of blades 603 as needed. One end of the blade 603 is fixed to the outside of the mounting sleeve 604. After the rotating shaft 602 is inserted and installed into the support sleeve 601, the mounting sleeve 604 is fixed to the bottom of the rotating shaft 602, and then the support sleeve 601 is installed into the second mounting hole 305, with sufficient force and stable fixation.

[0042] In a preferred embodiment, the support sleeve 601 is threadedly connected to the second mounting hole 305, and the mounting sleeve 604 is detachably connected to the rotating shaft 602. This improves the installation efficiency of the support sleeve 601 and the diversion shaft 3. Meanwhile, preferably, the mounting sleeve 604 is connected to the rotating shaft 602 in a sleeved form with an interference fit, ensuring sufficient contact area and good fixing effect. The support sleeve 601 can stably withstand the impact of the axial water flow along the diversion shaft 3 on the blade 603, resulting in good working performance.
