Description

Technical Field

[0001] The utility model relates to the technical field of multi-stage pumps, in particular to a mounting base for a multi-stage pump. Background Art

[0002] Vertical multistage pumps are mechanical devices that can transport everything from tap water to industrial liquids. They utilize a standard vertical motor and quick-release mechanical seal, making replacement very easy. The pump's flow path is constructed of stainless steel, suitable for handling mildly corrosive media. These components are typically secured to the top of a mounting base, requiring a mounting base for the multistage pump.

[0003] When installing a vertical multistage pump, it is generally fixed to the upper end of the mounting base by multiple bolts. Therefore, when the vertical multistage pump is to be disassembled and repaired, multiple bolts need to be loosened separately to separate the vertical multistage pump from the mounting base, which is time-consuming and labor-intensive. Moreover, when the vertical multistage pump is working outdoors, since a vertical motor is provided at the upper end of the vertical multistage pump, the tail of the vertical motor faces upward, and a fan blade cover at the tail of the motor is provided with a mesh for auxiliary heat dissipation. Moreover, since no rainproof mechanism is provided on the existing mounting base, rainwater can easily enter the interior of the vertical motor through the mesh of the fan blade cover in rainy and snowy weather, which is not conducive to the safe use of the vertical multistage pump. Therefore, it is necessary to propose a rainproof pipeline pump to solve the above-mentioned problems. Utility Model Content

The lower end of the rain shield 6 is fixedly connected to a rain cover 7. The front end of the connecting plate 3 is fixedly connected to baffles 8 respectively located on the left and right sides of the rain cover 7 and in contact with the lower end of the rain shield 6. A locking mechanism is provided on the upper sides of the two baffles 8.

[0020] A second T-shaped slot 11 is provided at the upper end of the mounting base 1, and a second T-shaped slider 12 is slidably connected inside the second T-shaped slot 11. A fixed plate 13 is fixedly connected to the upper end of the second T-shaped slider 12, and the vertical multi-stage pump 2 is fixedly connected to the upper end of the fixed plate 13. The upper end of the mounting base 1 is fixedly connected to vertical plates 14 located on the left and right sides of the fixed plate 13, respectively. A first positioning hole 16 is penetrated on one side of the two vertical plates 14, and a second positioning hole 15 corresponding to the two first positioning holes 16 is penetrated on the outer wall of the fixed plate 13. A limiting rod 17 matching the two first positioning holes 16 and the second positioning hole 15 is inserted into the inside of the two first positioning holes 16 and the second positioning hole 15, and a limiting mechanism is installed at the left end of the limiting rod 17.

[0021] In this embodiment, the first T-shaped slider 5 is inserted into the first T-shaped chute 4, and the rain shield 7 is located outside the vertical motor on the upper side of the vertical multi-stage pump 2. Then, the rain shield 6 and the rain shield 7 are slid downward as the first T-shaped slider 5 is inserted into the first T-shaped chute 4 until the rain shield 6 abuts against the two baffles 8. Then, the position of the rain shield 6 is locked by two locking mechanisms, and the fan blade cover on the upper side of the vertical motor is located inside the rain shield 7, thereby preventing rainwater from entering the interior of the vertical motor through the mesh holes at the fan blade cover, so as to prevent it from being unsafely used in rainy and snowy weather.

[0022] When the vertical multi-stage pump 2 is to be installed, the second T-shaped slider 12 needs to be fully inserted into the second T-shaped slide groove 11. Since the two match each other, the vertical multi-stage pump 2 is prevented from moving up, down, left and right. At this time, the two first positioning holes 16 and the second positioning holes 15 correspond to each other, and then the limit rod 17 is inserted into the inside thereof. Since they match each other, the vertical multi-stage pump 2 is prevented from moving forward and backward. The limit mechanism can prevent the limit rod 17 from moving to the right, and the installation of the vertical multi-stage pump 2 is completed. When it is to be disassembled, it is only necessary to remove the restriction of the limit mechanism on the rightward movement of the limit rod 17, and then pull the limit rod 17 to the right, thereby disengaging the second T-shaped slider 12 from the inside of the second T-shaped slide groove 11. It is simple to operate and easy to disassemble and assemble, and further achieves the effect of convenient separation of the vertical multi-stage pump 2 from the mounting base 1 when disassembling and repairing the vertical multi-stage pump 2, and saving time and effort.

[0023] As a technical optimization solution of the present invention, the locking mechanism includes a first screw 9 which is fixedly connected to the upper ends of the two baffles 8 and passes through the rain shield 6 through two circular holes. The outer walls of the two first screws 9 are threadedly connected with a locking block 10 which abuts against the upper end of the rain shield 6.

[0024] In this embodiment: when the rain shield 6 contacts the two baffles 8, the two first screws 9 pass through the rain shield 6 through the two circular holes respectively, and then the two locking blocks 10 are screwed into the outer walls of the two first screws 9, thereby locking the position of the rain shield 6.

[0025] As a technical optimization solution of the present invention, the limiting mechanism includes a second screw rod 19 fixedly connected to the left end of the limiting rod 17, and the outer wall screw of the second screw rod 19 is connected to a limiting nut 20 that contacts the left end of the left vertical plate 14.

[0026] In this embodiment, the limiting nut 20 is screwed into the second screw rod 19 until it contacts the left vertical plate 14 , thereby preventing the limiting rod 17 from moving rightward.

[0027] As a technical optimization solution of the present invention, the right end of the limiting rod 17 is fixedly connected to a limiting plate 18 that contacts the right end of the right vertical plate 14 .

[0028] In this embodiment, the limiting plate 18 is provided to prevent the limiting rod 17 from moving to the left.

[0029] As a technical optimization solution of the present invention, mounting plates 21 are fixedly connected to both the left and right sides of the mounting base 1 .

[0030] In this embodiment, two mounting plates 21 are provided to facilitate fixing the device by bolts.

[0031] As a technical optimization solution of the present invention, the outer walls of the two locking blocks 10 are both provided with anti-slip grooves.

[0032] In this embodiment, anti-slip grooves are provided to prevent slipping when the two locking blocks 10 are rotated.

[0033] Working principle: First, insert the first T-shaped slider 5 into the first T-shaped chute 4. At this time, the rain shield 7 is located outside the vertical motor on the upper side of the vertical multi-stage pump 2. Then, slide the rain shield 6 and the rain shield 7 downward as the first T-shaped slider 5 is inserted into the first T-shaped chute 4 until the rain shield 6 abuts against the two baffles 8, and the two first screws 9 pass through the rain shield 6 through the two circular holes respectively, and then screw the two locking blocks 10 into the outer walls of the two first screws 9, so as to lock the position of the rain shield 6, and the fan blade cover on the upper side of the vertical motor is located inside the rain shield 7, thereby preventing rainwater from entering the interior of the vertical motor through the mesh holes at the fan blade cover, so as to prevent it from being unsafe to use in rainy and snowy weather;

[0034] When the vertical multistage pump 2 is to be installed, the second T-shaped slider 12 needs to be fully inserted into the second T-shaped slide groove 11. Since the two match each other, the vertical multistage pump 2 is prevented from moving up, down, left, and right. At this time, the two first positioning holes 16 and the second positioning holes 15 correspond to each other, and then the limit rod 17 is inserted into the inside. Since they match each other, the vertical multistage pump 2 is prevented from moving forward and backward. Then the limiting nut 20 is screwed into the second screw 19 until it contacts the left vertical plate 14, thereby preventing The limiting rod 17 moves to the right, and the limiting plate 18 prevents the limiting rod 17 from moving to the left, thereby completing the installation of the vertical multi-stage pump 2. When it is to be disassembled, it is only necessary to remove the restriction on the rightward movement of the limiting mechanism on the limiting rod 17, and then pull the limiting rod 17 to the right, thereby disengaging the second T-shaped slider 12 from the interior of the second T-shaped slide groove 11. The operation is simple and the disassembly and assembly are convenient, further achieving the effect of convenient separation of the vertical multi-stage pump 2 from the mounting base 1 when disassembling and repairing the vertical multi-stage pump 2, and saving time and effort.
