Description

Technical Field

[0001] This utility model belongs to the technical field of water pump units, and more specifically, it relates to a fixed installation device for water pump units. Background Technology

[0002] A water pump unit is a set of equipment for transporting liquids, consisting of water pumps, a power unit, a transmission device, a base, and other components. Water pump units come in various types and specifications to meet different flow rate and head requirements, and are widely used in many fields such as agricultural irrigation, urban water supply, industrial production, and sewage treatment. Before use, the individual pumps of the water pump unit are usually limited and fixed by fixing devices.

[0003] In the existing technology, when the water pump is directly fixed by bolts, it is inconvenient to adjust the position of the water pump during installation and use, which can easily cause mismatch between the position of the pipeline and the water pump. When the water pump is fixed by pressing the water pump up and down with the pressing component and the base, the pressing component must also move when the water pump is moved left and right in the horizontal direction. This makes the position adjustment structure of a single water pump complex, costly and inconvenient to operate. Utility Model Content

[0004] The purpose of this utility model is to provide a fixed installation device for a water pump unit, which aims to solve the technical problems of complex structure, high cost and inconvenient operation of the existing single water pump position adjustment.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a fixed installation device for a water pump unit, comprising:

[0006] The base has a first direction and a second direction that are perpendicular to each other, and a plurality of upwardly extending fixing plates are provided at intervals along the first direction on the top.

[0007] Multiple sets of sliding plates are slidably connected to the base at intervals along the first direction; in the first direction, each set of sliding plates corresponds left and right to a set of fixed plates and is arranged parallel to each other; a first limiting member is provided between the multiple sets of sliding plates and the base; and

[0008] Multiple pairs of limiting plates correspond one-to-one with multiple sets of fixed plates; the two limiting plates in each pair are spaced apart and slidably connected to the base along the second direction, and each limiting plate is perpendicular to the corresponding fixed plate; a second limiting member is provided between each limiting plate and the base;

[0009] Each set of sliding plates, each set of fixed plates, and a pair of limiting plates corresponding to the fixed plates enclose a top-open limiting space, which is used to install a water pump.

[0010] In one possible implementation, the first limiting member includes:

[0011] Two first mounting screws are placed above the base and spaced apart on the front and rear sides of the fixing plate; the first mounting screws extend along the first direction;

[0012] Multiple pairs of first limiting nuts are spaced apart along the first direction and are threadedly connected to the first mounting screw;

[0013] Each of the first mounting screws passes sequentially through multiple sets of sliding plates along the first direction; each pair of first limiting nuts abuts against the left and right sides of the corresponding sliding plate to clamp the sliding plate.

[0014] In some embodiments, in the second direction, the fixing plate is disposed between two sets of the first mounting screws, and the front and rear sides of the sliding plate extend through the fixing plate; wherein the first mounting screws pass through the corresponding extension side of the sliding plate.

[0015] In one possible implementation, the second limiting member includes:

[0016] The second mounting screw has one end inserted into the base along the second direction and is fixed to the corresponding limiting plate;

[0017] A pair of second limiting nuts are screwed onto the second mounting screw at intervals and clamped on the inner and outer sides of the base.

[0018] In one possible implementation, the base is provided with a mounting groove extending along the first direction, the fixing plate is fixed in the mounting groove, and the sliding plate is slidably connected in the mounting groove;

[0019] The bottom of the mounting groove is provided with a downwardly recessed wire guide groove, which extends along the first direction.

[0020] In some embodiments, the mounting groove has multiple receiving cavities on its two opposite sides along the second direction, and the multiple receiving cavities are spaced apart along the first direction; a limiting plate is slidably connected in each receiving cavity.

[0021] For example, a relief groove is provided on the upper cavity wall of the receiving cavity, and the relief groove extends upward through the base.

[0022] For example, the lower cavity wall of the receiving cavity is provided with multiple guide grooves spaced apart along the first direction, and the guide grooves extend along the second direction; the bottom of the limiting plate is provided with multiple guide blocks corresponding to the guide grooves one by one, and the guide blocks are slidably connected in the corresponding guide grooves.

[0023] In one possible implementation, the base is provided with a plurality of spaced-apart portions along the second direction, and a third limiting member is provided between two adjacent limiting plates in the second direction.

[0024] In some embodiments, the third limiting member includes:

[0025] The third mounting screw has its two ends inserted into the two adjacent bases along the second direction and fixed to the two nearby limiting plates;

[0026] A pair of third limiting nuts are screwed onto the third mounting screw at intervals; the pair of third limiting nuts are correspondingly tightened on the inner sides of the two bases.

[0027] Compared with the prior art, the solution shown in this application, by sliding the sliding plate along the first direction to the base, allows adjustment of the distance between the sliding plate and the fixed plate, thereby adjusting the length of the limiting space in the first direction, so that the fixed plate and the sliding plate are clamped on the left and right sides of the water pump along the first direction. Furthermore, by setting multiple pairs of limiting plates and sliding them to the base, the distance between a pair of limiting plates in the second direction can be easily adjusted, thereby adjusting the width of the limiting space in the second direction, so that a pair of limiting plates are correspondingly clamped on the front and rear sides of the water pump along the second direction. The first limiting member is used to fix the position of the sliding plate after it has moved into place, and the second limiting member is used to fix the position of the corresponding limiting plate after each limiting plate has slid into place, so as to prevent the movement of the sliding plate or the limiting plate from affecting the positioning of the water pump. The water pump fixing solution provided in this application uses limiting in two mutually perpendicular directions to achieve the fixing and limiting of the water pump, which is simple in structure, low in cost, and easy to operate.

In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0037] It should be noted that the base 1 has a first direction and a second direction that are perpendicular to each other. Preferably, in this application, the length direction of the base 1 is used to indicate the first direction, and the width direction of the base 1 is used to indicate the second direction. The terms "left" and "right" used in this application refer to the first direction, and the terms "front" and "rear" refer to the second direction.

Figure 1 The direction indicated by the middle arrow B is used to indicate the second direction.

[0038] Please refer to the following: Figures 1 to 4 The present invention provides a description of the fixing and installation device for a water pump unit. The fixing and installation device includes a base 1, multiple sets of sliding plates 3, and multiple pairs of limiting plates 4. Multiple upwardly extending fixing plates 2 are spaced at intervals along a first direction on the top of the base 1. Multiple sets of sliding plates 3 are slidably connected to the base 1 at intervals along the first direction. In the first direction, each set of sliding plates 3 corresponds left and right to a set of fixing plates 2 and is arranged parallel to each other. A first limiting member 5 is provided between the multiple sets of sliding plates 3 and the base 1. Multiple pairs of limiting plates 4 correspond one-to-one with multiple sets of fixing plates 2. The two limiting plates 4 in each pair are spaced back and forth along a second direction and slidably connected to the base 1, and each limiting plate 4 is perpendicular to its corresponding fixing plate 2. A second limiting member 6 is provided between each limiting plate 4 and the base 1. Each set of sliding plates 3, each set of fixing plates 2, and a pair of limiting plates 4 corresponding to the fixing plate 2 enclose a top-open limiting space, within which a water pump is installed.

[0039] It should be understood that there are two limit plates 4 in each pair, and the two limit plates 4 are set one in front of the other along the second direction.

[0040] It should be noted that the base 1 has multiple sets of mounting threaded holes spaced apart along the first direction, and the fixing plate 2 is detachably connected to one set of threaded holes of the base 1 by bolts. Before installing the water pump, after determining the preset position of the water pump, the fixing plate 2 is installed in the corresponding threaded hole. Then, the position of the sliding plate 3 is moved to the specified distance between the fixing plate 2 and the sliding plate 3 to achieve preliminary positioning in the first direction. Then, the water pump is installed, and the position of the sliding plate 3 is fixed by the first limiting member 5. When there is a gap between the water pump and the fixing plate 2, a shim can be added between the fixing plate 2 and the water pump to clamp the water pump between the fixing plate 2 and the sliding plate 3. Then, the two sets of limiting plates 4 are moved to the specified position to form a distance between the two sets of limiting plates 4 equal to the size of the water pump in the second direction, achieving preliminary positioning in the second direction. The position of the limiting plate 4 is fixed by the second limiting member 6, thereby achieving the positioning of the limiting plate 4.

[0041] Furthermore, during subsequent pipeline installation, when the position of the water pump needs to be adjusted, the fixing of the first limiting member 5 and the second limiting member 6 can be released. Then, the position in the first direction can be adjusted first, followed by the position in the second direction. Specifically, the water pump is moved to the designated position along with the sliding plate 3. If the movement distance is large, the bottom bolts of the fixing plate 2 can be released, and the position of the mounting threaded hole of the fixing plate 2 can be changed. If the movement distance is small, the water pump can be clamped with the sliding plate 3 directly by adding or removing shims. After the position in the first direction is adjusted to the correct position, the front and rear limiting plates 4 are slid, so that a pair of limiting plates 4 are clamped on the front and rear sides of the water pump.

[0042] For example, the bottom of the sliding plate 3 is provided with a mounting plate, which extends toward the fixed plate 2 and is slidably connected to the mounting groove 11 on the base 1; the sliding plate 3 and the mounting plate form an L-shaped mounting seat, and the water pump is used to be mounted on the corresponding mounting plate.

[0043] It should be understood that the limiting plate 4 has a certain extension length in the first direction. However, when the position of the water pump is adjusted along the first direction, the adjustment distance is often less than half the length of the limiting plate 4 in the first direction. Therefore, even if the position of the water pump is adjusted in the first direction, the limiting plate 4 can still be pressed against the front or rear side of the water pump.

[0044] Compared with the prior art, the fixed installation device for the water pump unit provided by this utility model allows the sliding plate 3 to be slidably connected to the base 1 along the first direction, thereby adjusting the distance between the sliding plate 3 and the fixed plate 2, and thus adjusting the length of the limiting space in the first direction, so that the fixed plate 2 and the sliding plate 3 are clamped on the left and right sides of the water pump along the first direction. Furthermore, by setting multiple pairs of limiting plates 4 and slidably connecting the limiting plates 4 to the base 1, the distance between a pair of limiting plates 4 in the second direction can be easily adjusted, thereby adjusting the width of the limiting space in the second direction, so that a pair of limiting plates 4 are correspondingly clamped on the front and rear sides of the water pump along the second direction. Among them, the first limiting member 5 is used to fix the position of the sliding plate 3 after it moves into place, and the second limiting member 6 is used to fix the position of the corresponding limiting plate 4 after each limiting plate 4 slides into place, so as to prevent the movement of the sliding plate 3 or the limiting plate 4 from affecting the positioning of the water pump.

[0045] The water pump fixing scheme provided in this application uses two mutually perpendicular directions of limit to fix and limit the water pump. The structure is simple, the cost is low, and the operation is convenient. Moreover, the device does not require a rotating mechanism or a drive device. It mainly uses limit nuts to screw and limit, which is suitable for small factories with limited installation budgets. It should be understood that the sliding plate 3 and the limit plate 4 provided in this application can slide to different positions on the base 1 to adapt to water pumps of different widths, which is highly adaptable.

[0046] For example, the first limiting member 5 and the second limiting member 6 can be limiting screws. Each set of limiting plates 4 has multiple sets of adjusting screw holes spaced apart along the second direction at its bottom. The limiting plate 4 is fixed within one set of adjusting screw holes by the limiting screws. When the limiting plate 4 is installed in different adjusting screw holes, it can be limited to different positions in the second direction. Similarly, multiple sets of adjusting screw holes spaced apart along the first direction on the top of the base 1 can be used to adjust the positions of different sliding plates 3. It should be noted that this method of adjustment is suitable for situations where the adjustment precision is not high.

[0047] Please see Figure 1In some possible embodiments, the first limiting member 5 includes two first mounting screws 51 and multiple pairs of first limiting nuts 52; the two first mounting screws 51 are positioned above the base 1 and spaced apart on the front and rear sides of the fixing plate 2; the first mounting screws 51 extend along a first direction; the multiple pairs of first limiting nuts 52 are spaced apart along the first direction and threadedly connected to the first mounting screws 51; wherein each first mounting screw 51 passes through multiple sets of sliding plates 3 sequentially along the first direction; each pair of first limiting nuts 52 abuts against the left and right sides of the corresponding sliding plate 3 to clamp the sliding plate 3.

[0048] It should be understood that the first mounting screw 51 passes through the sliding plate 3, and the sliding plate 3 is slidably connected to the first mounting screw 51. That is, the size of the through hole on the sliding plate 3 suitable for the first mounting screw 51 to pass through is larger than the cross-sectional size of the first mounting screw 51 and smaller than the cross-sectional size of the first limiting nut 52.

[0049] Each set of sliding plates 3 has a first limiting nut 52 screwed onto its left and right sides along the first direction. By rotating the first limiting nut 52, one side of the first limiting nut 52 abuts against the sliding plate 3. When the two first limiting nuts 52 of the same pair abut against the left and right sides of the sliding plate 3 respectively, the position of the sliding plate 3 is fixed. The position of the sliding plate 3 in the first direction is adjusted by rotating the first limiting nut 52, and the sliding plate 3 is reliably fixed after adjustment, ensuring the stability of the water pump's limiting position in the first direction. This ensures the reliability of the entire fixed installation device in this direction and has better precision than the setting of adjusting screw holes, making it suitable for applications with high adjustment precision.

[0050] To facilitate the fixing of the first mounting screw 51, a set of fixing brackets is provided on both sides of the top of the base 1 along the first direction. The two ends of the first mounting screw 51 are fixed on the fixing brackets on both sides. At the same time, the second limiting member 6 is placed below the first mounting screw 51 and passes through the base 1, which can avoid mutual interference between the first mounting screw 51 and the second limiting member 6.

[0051] Please see Figure 1 In some embodiments, in the second direction, the fixing plate 2 is disposed between two sets of first mounting screws 51, and the front and rear sides of the sliding plate 3 extend through the fixing plate 2; wherein, the first mounting screws 51 pass through the corresponding extension side of the sliding plate 3.

[0052] By placing the fixing plate 2 between the two first mounting screws 51, interference between the fixing plate 2 and the first mounting screws 51 on both sides along the second direction can be avoided. By extending the front and rear sides of the sliding plate 3 through the fixing plate 2, it can be ensured that the front and rear sides of the sliding plate 3 correspond to the first mounting screws 51.

[0053] By setting the positions of the fixed plate 2 and the sliding plate 3 in a reasonable manner, it is ensured that there will be no interference from other components when adjusting the position of the sliding plate 3, which further improves the convenience and stability of adjusting and fixing the water pump in the first direction of the entire fixed installation device.

[0054] Please see Figure 3 In some possible embodiments, the second limiting member 6 includes a second mounting screw 61 and a pair of second limiting nuts 62; one end of the second mounting screw 61 passes through the base 1 along the second direction and is fixed to the corresponding limiting plate 4; the pair of second limiting nuts 62 are screwed onto the second mounting screw 61 at intervals and are clamped on the inner and outer sides of the base 1.

[0055] It should be understood that a pair of second limiting nuts 62 includes two second limiting nuts 62 respectively disposed inside and outside the base 1; in this application, a pair refers to two nuts.

[0056] Specifically, when the limiting plate 4 slides into place, one side of the second limiting nut 62 abuts against the inner side of the base 1, and the other side of the second limiting nut 62 abuts against the outer side of the base 1, thereby clamping the base 1 to achieve the limiting of the limiting plate 4 in the second direction.

[0057] In this application, after the limiting plate 4 is adjusted into position, the second limiting nut 62 can reliably fix the limiting plate 4 to the base 1, ensuring the stability of the water pump's limiting position in the second direction. This simple and effective fixing method ensures the positioning accuracy and reliability of the entire fixing installation device in the second direction, making the installation and fixing of the water pump in two mutually perpendicular directions more stable.

[0058] Please see Figure 2 In some possible embodiments, the base 1 is provided with a mounting groove 11 extending in a first direction, the fixing plate 2 is fixed in the mounting groove 11, and the sliding plate 3 is slidably connected in the mounting groove 11; the bottom of the mounting groove 11 is provided with a downwardly recessed wire passage groove 12, which extends in the first direction.

[0059] By setting the mounting groove 11, the water pump can slide along the sliding plate 3 and the mounting plate within the mounting groove 11. The mounting groove 11 provides a stable sliding track for the sliding plate 3, ensuring the smoothness and stability of the sliding plate 3 in the first direction. By setting the wire passage groove 12, the water pump's connection wire can be easily passed through the bottom of the mounting groove 11, avoiding the wire from being squeezed or damaged during installation and use, improving the safety and reliability of the entire device, and making the installation and maintenance of the equipment more convenient.

[0060] Please see Figure 2In some embodiments, the mounting groove 11 has multiple receiving cavities 13 on its two opposite sides along the second direction, and the multiple receiving cavities 13 are spaced apart along the first direction; a limiting plate 4 is slidably connected in each receiving cavity 13.

[0061] It should be understood that the multiple receiving cavities 13 on one side of the groove wall of the mounting groove 11 correspond one-to-one with the multiple limiting plates 4.

[0062] Specifically, the second mounting screw 61 passes through the base 1 along the second direction and extends into the receiving cavity 13, and is fixed with the corresponding limiting plate 4; a pair of second limiting nuts 62 are screwed onto the second mounting screw 61 at intervals; one of the second limiting nuts 62 is placed in the receiving cavity 13 and abuts against the groove wall of the receiving cavity 13 away from the mounting groove 11, and the other second limiting nut 62 abuts against the outside of the base 1.

[0063] Since the receiving cavity 13 is located below the first mounting screw 51, interference between the second mounting screw 61 and the first mounting screw 51 can be avoided. Therefore, placing the limiting plate 4 within the receiving cavity 13 achieves a reasonable layout of the device, ensuring that the sliding and limiting between the limiting plate 4 and the sliding plate 3 do not affect each other. The receiving cavity 13 provides a dedicated sliding space for the limiting plate 4, facilitating its sliding within the cavity, thus making the sliding of the limiting plate 4 in the second direction more orderly and stable. Simultaneously, it facilitates the second limiting nut 62 abutting against the inside of the receiving cavity 13, with another second limiting nut 62 abutting against the outside of the base 1 and positioned opposite to the second limiting nuts 62 of the same pair, thereby clamping the base 1 and achieving stable limiting.

[0064] Please see Figure 2 For example, a relief groove 14 is provided on the upper cavity wall of the receiving cavity 13, and the relief groove 14 extends upward through the base 1.

[0065] By setting the relief groove 14, the second limiting nut 62 inside the base 1 can be rotated easily at the relief groove 14, avoiding interference.

[0066] It should be noted that the size of the relief groove 14 in the first direction is smaller than the size of the receiving cavity 13 in the first direction, so as to prevent the limiting plate 4 from disengaging from the top relief groove 14 into the receiving cavity 13.

[0067] Furthermore, a connecting part 42 extending into the receiving cavity 13 is provided on the top of the limiting plate 4. The connecting part 42 is used to prevent the side of the limiting plate 4 away from the water pump from leaving the receiving cavity 13. Optionally, a stepped surface is provided in the receiving cavity 13 to limit the connecting part 42 at the corresponding stepped surface, so as to limit the limiting plate 4 and prevent the limiting plate 4 from leaving the receiving cavity 13 in the second direction.

[0068] Please see Figure 2For example, the lower cavity wall of the receiving cavity 13 is provided with multiple guide grooves 15 spaced apart along the first direction, and the guide grooves 15 extend along the second direction; the bottom of the limiting plate 4 is provided with multiple guide blocks 41 corresponding to the guide grooves 15 one by one, and the guide blocks 41 are slidably connected in the corresponding guide grooves 15.

[0069] The sliding engagement of the guide groove 15 and the guide block 41 is used to guide the sliding of the limit plate 4, preventing the limit plate 4 from deviating from the preset direction during the sliding process. This further improves the smoothness of the sliding of the limit plate 4 in the second direction and the stability of the entire fixed installation device, ensuring the accurate installation and reliable fixation of the water pump in the second direction.

[0070] For example, there are two guide grooves 15, which are respectively close to the two sides of the limiting plate 4 in the first direction, so that the left and right sides of the limiting plate 4 slide in the same direction.

[0071] Please see Figure 4 In some possible embodiments, the base 1 is provided with multiple spaced-apart members along the second direction, and a third limiting member 7 is provided between two adjacent limiting plates 4 in the second direction.

[0072] It should be understood that the third limiting member 7 can replace the second limiting member 6 between two adjacent sets of bases 1. Through a set of third limiting members 7, the front and rear limiting plates 4 can be limited, thereby improving the fixing and limiting efficiency.

[0073] Please see Figure 4 In some embodiments, the third limiting member 7 includes a third mounting screw 71 and a pair of third limiting nuts 72; the two ends of the third mounting screw 71 pass through two adjacent bases 1 along the second direction and are fixed to two adjacent limiting plates 4; the pair of third limiting nuts 72 are screwed onto the third mounting screw 71 at intervals; the pair of third limiting nuts 72 are screwed onto the inner side of the two bases 1 respectively.

[0074] When the distance between two sets of water pumps set in the front and back in the second direction is constant, the positions of the two adjacent limit plates 4 of the two water pumps can be fixed by fixing a pair of third limit nuts 72, thereby improving the efficiency of positioning and fixing.

[0075] It should be understood that since the distance between the two sets of water pumps set in the second direction is fixed, the distance between the two adjacent limit plates 4 connected to the third limit member 7 is also fixed. When the position of one limit plate 4 is determined, the position of the other limit plate 4 is also determined. At this time, it is only necessary to tighten the third limit nut 72 to fix the two limit plates 4.

[0076] Optionally, when the distance between the two sets of water pumps set in the second direction is not a fixed value, the positions of the two adjacent limit plates 4 of the two water pumps can be fixed by fixing two pairs of third limit nuts 72, thereby improving the efficiency of positioning and fixing.

[0077] Optionally, when the distance between the two sets of water pumps arranged in the front and back in the second direction is not a constant value, the third limiting member 7 includes two mounting sleeves and a screw rod. The two mounting sleeves are fixed to the two adjacent limiting plates 4 and extend in the opposite direction, passing through the corresponding base 1. The mounting sleeves are provided with internal threads, and the screw rod is provided with external threads. The screw rod is screwed to the protruding ends of the two mounting sleeves. By rotating the screw rod, the two mounting sleeves can move in opposite directions to move closer to or further away from each other, thus limiting the limiting plates 4. By rotating the screw rod, the relative distance between the two limiting plates 4 can be adjusted.

[0078] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
