[0003] At present, during the installation process, the centrifugal pump control cabinet of the prior art generally needs to be welded to the same supporting base at the bottom together with the centrifugal pump. However, this welding method causes the control cabinet to be firmly welded and fixed on the supporting base, which brings inconvenience especially when the control cabinet needs to be disassembled separately for maintenance, and brings inconvenience when assembling the control cabinet and the supporting base. Welding is time-consuming and labor-intensive, and the assembly efficiency is low. Secondly, there is no structure on the inside of the cabinet door of the control cabinet for placing maintenance tools, which causes the maintenance tool box to be placed on the ground. When the maintenance personnel inspect the high inside of the control cabinet, they need to bend down to the ground to get the maintenance tools, which brings inconvenience to the maintenance process. For this reason, we propose a centrifugal pump control cabinet. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Example

[0025] Generally, it is necessary to be welded synchronously with the centrifugal pump on the same supporting base 1 at the bottom, but this welding method causes the control cabinet to be firmly welded and fixed on the supporting base 1, which brings inconvenience especially when the control cabinet needs to be disassembled separately for maintenance, and brings inconvenience when assembling the control cabinet and the supporting base 1. Welding is time-consuming and labor-intensive, and the assembly efficiency is low. Secondly, there is no structure on the inside of the cabinet door 21 of the control cabinet for placing maintenance tools, resulting in the maintenance tool box needing to be placed on the ground. When maintenance personnel inspect the high inside of the control cabinet, they need to bend down to the ground manually to get the maintenance tools, which brings inconvenience to the maintenance process.

[0027] The convenient fixing component 3 is used to quickly realize the assembly or disassembly between the cabinet 2 and the supporting base 1;

[0028] The foldable support assembly 4 is used by maintenance personnel to place maintenance tools on the cabinet door 21 when repairing the control cabinet, avoiding the need to bend over to the ground to pick up tools.

[0029] Among them, a centrifugal pump body is also provided on the rear side of the control cabinet, and the bottom end of the centrifugal pump body is also assembled and fixed between the convenient fixing component 3 and the supporting base 1.

[0030] Specifically, refer to Figure 4-5In order to facilitate and quickly assemble the control cabinet on the support base 1 provided at the bottom, a convenient fixing component 3 is provided, including two symmetrically arranged plug blocks 31 fixed at the bottom end of the cabinet body 2, and the support base 1 is provided with slots matching the plug blocks 31, and the two plug blocks 31 are movably connected with a clamping rod 32, and the plug blocks 31 are provided with a clamping groove matching the clamping rod 32, and the vertical section of the clamping rod 32 is a right-angled trapezoidal structure, and a turntable 34 is provided between the two clamping rods 32, which is rotatably connected to the bottom end of the support base 1 through a rotating shaft 33, and the turntable 34 is provided with two inclined grooves arranged in a ring array, and the inclined grooves are movably sleeved on the outer side of the guide column 35, The top ends of the guide columns 35 are fixed to the bottom ends of the clamping rods 32, and the top ends of the two clamping rods 32 are fixed with sliders a36 with inverted convex structures in vertical cross-section. The sliders a36 are slidably connected to the slide groove a provided at the bottom end of the support base 1, and the opposite ends of the two sliders a36 are connected to the inner wall of the slide groove a through springs a310. A worm gear 37 fixed to the outside of the rotating shaft 33 is provided above the turntable 34, and a worm 38 is meshingly connected to the outside of the worm gear 37. A transmission shaft 39 is fixed to the mounting shaft hole of the worm 38, and the front end of the transmission shaft 39 is rotatably connected to the bottom end of the support base 1 through a bearing seat, and a handle is also fixed to the front end extension of the transmission shaft 39.

[0031] Among them, the inclined surfaces at one end of the two clamping rods 32 that are away from each other are for the convenience of actively squeezing the inclined end of the clamping rod 32 after the insert block 31 is inserted into the slot, until the inclined end of the clamping rod 32 is clamped in the clamping groove provided on the insert block 31 through the reverse action of the spring a310, that is to say, there is no need to rotate the transmission shaft 39 by the handle during assembly, and the worm 38 only needs to be manually rotated during disassembly.

[0032] Specifically, refer to Figure 5 In order to facilitate maintenance personnel to place maintenance tools in the middle of the cabinet door 21 and avoid the need for maintenance personnel to bend down to the ground to pick up maintenance tools, a foldable support component 4 is provided, including an L-shaped support plate 41 hinged at the middle position of the inner side surface of the cabinet door 21, and an inverted L-shaped card plate 42 is movably overlapped on the top surface of the L-shaped support plate 41, and a slider b43 with a convex cross-section is fixedly connected to one end of the inverted L-shaped card plate 42, and the slider b43 is slidably connected to the slide groove b provided on the inner side surface of the cabinet door 21, and the top end of the slider b43 is connected to the inner top wall of the slide groove b through a spring b44.

[0033] When the L-shaped support plate 41 is placed down, a side wall of the L-shaped support plate 41 close to the inner side of the cabinet door 21 will fit against the inner side of the cabinet door 21, thereby forming a supporting effect, making it convenient to place maintenance tools on the top of the L-shaped support plate 41, bringing convenience to maintenance personnel during maintenance.

[0034] Working principle: When using the centrifugal pump control cabinet, when it is necessary to disassemble the cabinet body 2 and the support base 1, the worm 38 connected to the transmission shaft 39 can be rotated by the handle, and the worm 38 drives the worm wheel 37 to rotate. Combined with the action of the two inclined grooves on the turntable 34, the two guide pillars 35 respectively drive the clamping rod 32 to move relative to each other, and cause the slider a36 to compress the spring a310, and at the same time, one end of the clamping rod 32 is disengaged from the clamping groove provided on the plug block 31. At this time, the plug blocks 31 are all pulled out of the slots provided on the support base 1, so as to achieve the purpose of convenient disassembly and subsequent maintenance. Secondly, during the maintenance process, the cabinet door 21 is opened, and the inverted L-shaped clamping plate 42 is pushed up, and the inverted L-shaped clamping plate 42 is disengaged from the overlapping obstruction of the L-shaped support plate 41, so that the L-shaped support plate 41 can be placed down, which is convenient for maintenance personnel to place the maintenance tool box, which brings convenience to maintenance personnel during maintenance.
