Description

Technical Field

[0001] This utility model relates to the technical field of water pump testing equipment, and in particular to a novel water pump testing device. Background Technology

[0002] As a key piece of equipment for fluid transportation, water pumps typically require testing of critical performance parameters such as flow rate, head, and efficiency before leaving the factory or during use to ensure they meet design requirements and operating standards. A fundamental step in water pump performance testing is reliably mounting the pump under test on a testing bench and precisely connecting its input and output ends to the testing pipeline system.

[0003] In current technical practices, the pipe interface positions of many pump testing benches are relatively fixed, or only offer a limited adjustment range. When testing pumps of different models and sizes, the differences in the spacing, height, and diameter of the inlet and outlet of each pump necessitate that operators spend a significant amount of time on alignment and connection work. This typically involves using multiple tools such as wrenches to loosen flange bolts, adjust pipe supports, or replace connecting short pipes. The entire process is not only cumbersome and labor-intensive, but also requires a certain level of experience and skill from the operators.

[0004] This clamping method, which relies on manual labor and tools for repeated fine-tuning, lacks an integrated adjustment and locking structure capable of quickly responding to changes in different pump sizes. This directly leads to inefficient pre-test preparation, limited versatility, and difficulty in meeting the rapid testing needs of various types and small batches of pumps, thus prolonging the overall testing cycle.

[0005] Therefore, this utility model proposes a novel water pump testing device to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a novel water pump testing device, which aims to improve the problems of complex adjustment structure, low clamping efficiency and poor versatility of the existing novel water pump testing devices. This utility model aims to provide a novel water pump testing device with an improved structure that can effectively solve the above problems.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a novel water pump testing device, comprising: a support, a support plate fixedly connected to the support, a fixing plate slidably connected to the support plate, an input pipe fixedly connected to the fixing plate, a fixing seat fixedly connected above the support, a sliding plate slidably connected to the fixing seat, and a testing pipe fixedly connected to the sliding plate.

[0008] The support plate has multiple first limiting holes, and the fixed plate is rotatably connected to a limiting plate. The limiting plate is fixedly connected to a first limiting post that selectively inserts into the first limiting holes.

[0009] At least two second limiting posts are fixedly installed on the fixed base, and a limiting block is provided on the sliding plate that can engage with the second limiting posts under the elastic force of the second spring. Through the cooperation between the second limiting posts and the limiting block, the position of the detection tube is quickly locked.

[0010] Preferably, the sliding plate is further provided with an installation component, the installation component including symmetrically arranged fixing rings, the fixing rings surrounding the outer periphery of the detection tube.

[0011] Preferably, the mounting assembly further includes a first connecting rod, symmetrical second connecting rods, and a third connecting rod, wherein the rear end of the fixing ring is connected to the third connecting rod via the second connecting rod, and the upper end of the third connecting rod is connected to the first connecting rod.

[0012] Preferably, the third connecting rod has a limiting groove for sliding engagement with the second connecting rod.

[0013] Preferably, the mounting assembly further includes a third limiting post for locking the position of the third connecting rod, and the third connecting rod has a second limiting hole for the insertion of the third limiting post.

[0014] Preferably, the mounting assembly further includes a limiting frame and a third spring, wherein the third limiting post is movably inserted within the limiting frame and is driven by the third spring to engage with the second limiting hole.

[0015] The fixing plate is also provided with a first spring connected to the first limiting post, which is used to provide a restoring force for the limiting plate.

[0016] Preferably, the second spring is sleeved on the outer periphery of the limiting block, and the two ends of the second spring abut against the flange of the limiting block and the inner wall of the sliding plate, respectively.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, by setting a fixed plate that can slide and lock laterally on the support plate, and a sliding plate that can slide and lock longitudinally on the fixed seat, the problem of existing detection devices being difficult to adapt to water pumps of different specifications and sizes due to their fixed structure and having poor versatility is solved. This achieves the technical effect of being able to quickly adjust and be compatible with multiple water pumps, and significantly improving the versatility of the equipment.

[0019] 2. This utility model, by adopting a quick positioning structure consisting of a spring, a limiting post, and a limiting block, and a clamping mechanism linked by a pull rod, solves the problems of repeated tightening with tools, cumbersome operation procedures, and excessive time consumption in the prior art. It achieves the technical effect of simplifying operation steps, quickly completing pipeline connection and fixation without tools, thereby significantly shortening the testing cycle and improving testing efficiency.

[0027] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please refer to Figures 1 to 5 This utility model provides a novel water pump testing device, which aims to solve the problems of complex structural adjustment, low clamping efficiency and insufficient connection reliability of existing water pump testing devices when adapting to water pumps of different specifications.

[0029] like Figure 1 As shown, the novel water pump testing device includes a support 1, a support plate 301 fixedly connected to the side of the support 1, and a fixed seat 308 fixedly connected to the top of the support 1. The support 1 serves as the mounting base for the entire device. The support plate 301 and the fixed seat 308 together form the support frame for the adjustment mechanism. Specifically, a fixed plate 303 is slidably connected to the support plate 301, and an input pipe 304 is fixedly connected to the front end of the fixed plate 303. To achieve rapid positioning of the fixed plate 303, multiple first limiting holes 302 are opened on the support plate 301 along the horizontal direction. A first limiting post 307 is retractably inserted into the fixed plate 303. The front end of the first limiting post 307 can selectively engage with any one of the first limiting holes 302, thereby locking the fixed plate 303 at a specific position on the support plate 301. To control the extension and retraction of the first limiting post 307, a limiting plate 305 is also movably connected to the fixed plate 303. A first spring 306 is provided inside the fixed plate 303. One end of the first spring 306 abuts against the first limiting post 307, and the other end abuts against the inner wall of the fixed plate 303. A spring force is always applied to the first limiting post 307 toward the first limiting hole 302. By operating the limiting plate 305, the first limiting post 307 can overcome the spring force of the first spring 306 and disengage from the first limiting hole 302. A sliding plate 309 is slidably connected to the fixed base 308. A detection tube 313 is fixedly connected to the front end of the sliding plate 309. To achieve rapid positioning of the sliding plate 309, at least two mutually spaced second limiting posts 312 are fixedly provided on the upper surface of the fixed base 308. A limiting block 310 is movably provided on the sliding plate 309. The sliding plate 309 is also provided with a second spring 311. One end of the second spring 311 is connected to the limiting block 310, and the other end abuts against the inner wall of the sliding plate 309. Under the elastic force of the second spring 311, a part of the limiting block 310 can be engaged between the two second limiting posts 312, thereby locking the sliding plate 309 in a specific position on the fixed seat 308. When the limiting block 310 is pressed, the limiting block 310 compresses the second spring 311 and disengages from the engagement state with the second limiting posts 312, so that the sliding plate 309 can slide freely.

[0030] Furthermore, referring to Figure 1 and Figure 4To ensure reliable fixation at the pipe connection, the sliding plate 309 is also equipped with an installation component 4. The installation component 4 includes symmetrically arranged fixing rings 406, which surround the outer periphery of the detection tube 313. The rear end of the fixing rings 406 is rotatably connected to a third connecting rod 404 via symmetrically arranged second connecting rods 403. To guide the movement trajectory of the second connecting rod 403, a limiting groove 405 is provided on the third connecting rod 404 for sliding engagement with the second connecting rod 403. The upper end of the third connecting rod 404 is rotatably connected to a first connecting rod 402 for driving the entire linkage mechanism. When the first connecting rod 402 is pulled upward, the third connecting rod 404 is driven to move upward, while the second connecting rod 403 moves both upward and inward under the constraint of the limiting groove 405. The contraction drives the retaining ring 406 to clamp. To lock the mounting assembly 4 in the clamped state, the third connecting rod 404 has a second limiting hole 401. The mounting assembly 4 also includes a third limiting post 409, a third spring 407, and a limiting frame 408. The third limiting post 409 is movably inserted into the limiting frame 408. The third spring 407 is located between the limiting frame 408 and the third limiting post 409 and always applies a spring force toward the second limiting hole 401 to the third limiting post 409. By rotating the third limiting post 409, it is disengaged from the limiting edge of the limiting frame 408. Under the action of the third spring 407, the third limiting post 409 automatically inserts into the second limiting hole 401, thereby locking the third connecting rod 404 in the position after upward movement, thus achieving the locking of the clamped state.

[0031] As a preferred embodiment, to achieve reliable clamping at the connection, please refer to... Figure 4 The linkage structure of the mounting component 4 is as follows: one end of the second connecting rod 403 is rotatably connected to the rear end of the fixing ring 406 via a pin, and the other end of the second connecting rod 403 is slidably fitted in the limiting groove 405 opened on the third connecting rod 404. The upper end of the third connecting rod 404 is rotatably connected to the lower end of the first connecting rod 402 via a pin. Through this linkage structure, the vertical linear motion of the first connecting rod 402 can be converted into the radial clamping and loosening action of the fixing ring 406.

[0032] As another preferred embodiment, to lock the mounting component 4 in a clamped state, please refer to... Figure 1 and Figure 4A limiting frame 408 is fixedly provided on the third connecting rod 404. The third limiting post 409 is movably inserted into the limiting frame 408. The third spring 407 is sleeved on the outer periphery of the third limiting post 409, and the two ends of the third spring 407 abut against the flanges of the limiting frame 408 and the third limiting post 409, respectively. By rotating the third limiting post 409, it is disengaged from the limiting edge of the limiting frame 408. Under the elastic force of the third spring 407, the third limiting post 409 can automatically insert into the second limiting hole 401 opened on the third connecting rod 404.

[0033] As another preferred embodiment, in order to achieve automatic reset and locking of the first limiting post 307, please refer to... Figure 3 The fixing plate 303 is also provided with a first spring 306. The first spring 306 is connected to the limiting plate 305 or the first limiting post 307. After the limiting plate 305 is moved by an external force, the first spring 306 can provide a restoring force to drive the limiting plate 305 to rotate in the opposite direction, so that the first limiting post 307 is automatically inserted into the aligned first limiting hole 302.

[0034] As another preferred embodiment, to make the locking structure more compact and reliable, please refer to... Figure 5 The second spring 311 is sleeved on the outer periphery of the limiting block 310, and the two ends of the second spring 311 abut against the flange of the limiting block 310 and the inner wall of the sliding plate 309, respectively. By pressing the limiting block 310, it can overcome the elastic force of the second spring 311 and retract.

[0035] Working principle: During clamping, the operator first moves the limiting plate 305 on the fixed plate 303 in the adjustable assembly 3, causing it to rotate around the pivot point and overcome the tension of the first spring 306. During the rotation, the first limiting post 307 fixed on the limiting plate 305 is synchronously driven, thereby disengaging from the first limiting hole 302. At this time, the fixed plate 303 can slide freely on the support plate 301, driving the input pipe 304 to move to align with and connect to the input end of the water pump body 2 under test. After connection, the limiting plate 305 is released. Under the restoring force of the first spring 306, the limiting plate 305 drives the first limiting post 307 to automatically reset and insert into the nearest first limiting hole 302, completing the rapid positioning and fixing of the input end.

[0036] Subsequently, the operator presses the limiting block 310 on the sliding plate 309. The limiting block 310 is pressed into the sliding plate 309 and compresses the second spring 311, causing its locking part to disengage from the locking of the second limiting post 312 on the fixed seat 308. At this time, the sliding plate 309 can slide freely on the fixed seat 308, driving the detection tube 313 to move to align with and connect to the output end of the water pump body 2 under test. After the connection is in place, the limiting block 310 is released, and the second spring 311 resets and pushes the limiting block 310 to automatically lock into the two second limiting posts 312, completing the rapid positioning and fixing of the output end.

[0037] To ensure the sealing and reliability of the output connection, the operator pulls the first connecting rod 402 of the mounting assembly 4 upwards. The first connecting rod 402 drives the third connecting rod 404 to move upwards. The symmetrical second connecting rod 403 is linked under the constraint of the limiting groove 405, which in turn drives the symmetrical fixing ring 406 to tighten and firmly clamp at the connection between the detection tube 313 and the water pump body 2. Finally, the third limiting post 409 is rotated to release it from the constraint of the limiting frame 408. The third spring 407 then pushes the third limiting post 409 into the second limiting hole 401, completing the locking of the entire clamping state. When disassembling, the operation can be reversed to quickly separate the parts.
