[0025] 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.

[0026] Specific implementation examples are given below.

[0027] Please see Figure 1 , Figure 2 , Figure 4This utility model provides a flood control pump guide cover that is easy to assemble quickly, including a mixed-flow pump 1; characterized in that: the inlet flange of the mixed-flow pump 1 is connected to a flange 11; the inner wall of the flange 11 is threadedly connected to a left cover 12 and a right cover 13; the side wall of the left cover 12 has multiple sets of first slots 14 and sliding grooves 15; a spring rod 16 is fixedly connected to the inner wall of the first slot 14; a buckle bracket 17 is fixedly connected to the end of the spring rod 16; the buckle bracket 17 is slidably connected to the side wall of the first slot 14; and multiple sets of buckle blocks 1 are fixedly connected to the side wall of the right cover 13. 8; The first slot 14 corresponds to the position of the latching block 18; The latching block 18 is slidably connected to the side wall of the first slot 14; The latching block 18 is slidably connected to the inner side wall of the latching frame 17; A control post 19 is fixedly connected to the end of the latching frame 17; The control post 19 is slidably connected to the inner side wall of the slide groove 15; First, before moving the right cover 13 closer to the left cover 12, manually pull the control post 19 outward to drive the latching frame 17 to slide into the first slot 14, while compressing the spring rod 16, and then let the latching block 18 slide into the first slot 14, and then release the control post. 19. The spring rod 16 generates a rebound force that acts on the latching frame 17, causing it to reset. During the reset movement, the latching frame 17 first engages with the latching block 18, and as the reset progresses, it fully engages with the latching block 18. After the latching frame 17 resets, it achieves a locking effect on the latching block 18, thus enabling the assembly of the left cover 12 and the right cover 13. The two sets of latching mechanisms of different sizes ensure that different areas bear the latching force, evenly distributing stress and reducing the risk of local deformation or breakage. The assembly is then completed. The left cover 12 and right cover 13 are threadedly fastened to the flange 11, and then the whole assembly is flanged to the mixed flow pump 1. During cleaning and maintenance, the disassembly can be achieved simply by unthreading the left cover 12 and right cover 13 to the flange 11 and then releasing the snap-fit ​​connection. The threaded and snap-fit ​​connection enables flexible and quick installation and disassembly, reducing installation and disassembly time and improving the efficiency of cleaning and maintenance. At the same time, after cleaning, the flow guide can be assembled by flexible snap-fit ​​connection and thread rotation, improving maintenance efficiency.

[0028] Furthermore, such as Figure 3 , Figure 4As shown, the left cover 12 has symmetrically opened second slots 2 on its side wall; a magnet frame 21 is fixedly connected to the inner side wall of the second slot 2; a magnet block 22 is symmetrically fixed to the side wall of the right cover 13; the magnet block 22 is slidably connected to the side wall of the magnet frame 21; when the right cover 13 is spliced ​​close to the left cover 12, a magnetic attraction effect will be generated as the distance between the magnet block 22 and the magnet frame 21 decreases, guiding the snap-fit ​​connection between the left cover 12 and the right cover 13 to the corresponding position. At the same time, after the magnet block 22 is completely slid into the magnet frame 21, it cooperates with the snap-fit ​​connection to improve the stability of the spliced ​​connection.

[0029] Furthermore, such as Figure 3 As shown, the left cover 12 and the right cover 13 have limiting grooves 3 on their side walls; filter screens 31 are provided at the ends of the left cover 12 and the right cover 13; steel rubber blocks 32 are symmetrically fixed to the side walls of the filter screens 31; steel rubber blocks 32 are slidably connected to the side walls of the limiting grooves 3; by applying pressure to the steel rubber blocks 32, they are squeezed and slid into the limiting grooves 3, thereby achieving the splicing of the filter screens 31 with the left cover 12 and the right cover 13. When the steel rubber blocks 32 slide into the limiting grooves 3, they will fill the inside of the limiting grooves 3. Only when subjected to an outward pulling force can they be separated from the left cover 12 and the right cover 13, improving the stability of the splicing installation. At the same time, the external pulling force can flexibly achieve the removal of the filter screens 31, making it easy to clean and replace them, and improving the isolation effect.

[0030] Furthermore, such as Figure 2 , Figure 5 As shown, the flange 11 has multiple sets of buffer grooves 4 on its side wall; a spring assembly 41 is fixedly connected to the side wall of the buffer groove 4; a rubber ring 42 is fixedly connected to the end of the spring assembly 41; when the flange 11 is connected to the mixed flow pump 1, the rubber ring 42 is squeezed and the spring assembly 41 is compressed. At this time, the spring assembly 41 generates a rebound force on the rubber ring 42, producing a bidirectional squeezing effect, thereby compressing and expanding the rubber ring 42, filling the gap in the flange connection, and improving the sealing effect.

[0031] Furthermore, such as Figure 4 As shown, sealing frames 5 are symmetrically fixed to the side walls of the left cover 12 and the right cover 13. When the left cover 12 and the right cover 13 are assembled and spliced, the sealing frames 5 will be squeezed to fill the splicing gap, thereby achieving a sealing effect and reducing fluid leakage.

[0032] Furthermore, such as Figure 4As shown, a snap-fit ​​block 6 is fixedly connected to the side wall of the first slot 14; a snap-fit ​​block 18 is slidably connected to the inner side wall of the snap-fit ​​block 6; when the snap-fit ​​frame 17 completes the reset action, it will drive the snap-fit ​​block 18 to slide into the inner side wall of the snap-fit ​​block 6, thereby increasing the friction between the snap-fit ​​block 6 and the snap-fit ​​block 18 and improving the stability of the snap-fit ​​block 18.

[0033] Furthermore, such as Figure 5 As shown, a rubber frame 7 is provided on the side wall of the second slot 2; the inner area of ​​the rubber frame 7 is proportionally smaller than the inner area of ​​the magnet frame 21; since the inner area of ​​the rubber frame 7 is proportionally smaller than the inner area of ​​the magnet frame 21, when the magnet block 22 is inserted into the magnet frame 21, it is restrained by the rubber frame 7, and the friction between it and the magnet block 22 is increased, thereby reducing the possibility of the magnet block 22 slipping out and improving the stability of the magnetic attraction.

[0034] Working principle: First, before moving the right cover 13 closer to the left cover 12, manually pull the control column 19 outward to drive the latching bracket 17 to slide into the first slot 14, while simultaneously compressing the spring rod 16. Then, the latching block 18 slides into the first slot 14. Afterward, release the control column 19, and the spring rod 16 generates a rebound force that acts on the latching bracket 17, causing it to reset. During the reset movement, the latching bracket 17 first engages with the latching block 18, and as the reset movement continues, it fully engages with the latching block 18. Once the latching bracket 17 has reset, it achieves a locking effect on the latching block 18, thereby assembling and connecting the left cover 12 and the right cover 13. Two sets of snap-fit ​​splicing mechanisms of different sizes achieve snap-fit ​​bearing force in different areas, which can evenly distribute stress and reduce the risk of local deformation or breakage. Then, the spliced ​​left cover 12 and right cover 13 are threadedly fastened to the flange 11, and then the whole is flanged to the mixed flow pump 1. During cleaning and maintenance, the dismantling operation can be achieved simply by unthreading the left cover 12 and right cover 13 to the flange 11 and then releasing the snap-fit ​​connection. When the right cover 13 is spliced ​​close to the left cover 12, the magnetic attraction effect is generated as the distance between the magnet block 22 and the magnet frame 21 decreases, guiding the snap-fit ​​connection of the left cover 12 and right cover 13 to the corresponding position. By utilizing the high-strength elastic deformation characteristics of the steel-rubber block 32, pressure is applied to the steel-rubber block 32, squeezing it into the limiting groove 3, thereby achieving the splicing of the filter screen 31 with the left cover 12 and the right cover 13. When the steel-rubber block 32 slides into the limiting groove 3, it will fill the inside of the limiting groove 3. Only when subjected to external outward pulling force can it be separated from the left cover 12 and the right cover 13, improving the stability during splicing and installation. At the same time, the filter screen 31 can be flexibly removed by external pulling force. When the flange 11 is flanged to the mixed flow pump 1, the rubber ring 42 is squeezed and the spring assembly 41 is compressed. At this time, the spring assembly 41 generates a rebound force acting on the rubber ring 42. The rubber ring 42 is subjected to bidirectional compression, causing it to compress and expand, filling the gap in the flange connection. When the left cover 12 and the right cover 13 are assembled, the sealing frame 5 is compressed to fill the gap. When the snap-fit ​​bracket 17 completes its reset action, it drives the snap-fit ​​block 18 to slide into the inner wall of the snap-fit ​​groove block 6. The snap-fit ​​groove block 6 increases the friction between the snap-fit ​​block 18 and the snap-fit ​​block 18, improving the stability of the snap-fit ​​block 18. Since the inner area of ​​the rubber frame 7 is proportionally smaller than the inner area of ​​the magnet frame 21, when the magnet block 22 is inserted into the magnet frame 21, it is restrained by the rubber frame 7, which also increases the friction between the magnet block 22 and the magnet block 22.

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.
