[0002] A marine pump is a water pump used on ships, usually used to move water from one place to another on the ship. These pumps can be used for a variety of purposes, including drainage, supplying clean water, cooling engines or other mechanical equipment, cabin drainage, and emergency drainage in case of fire. During the production process, marine pumps need to be fully evaluated through performance test devices, including flow, pressure, efficiency, power and other parameters. This is essential to verify whether the design of the pump meets the requirements, detect whether the pump has performance problems, and evaluate its working status, which helps to improve product quality and reliability.
[0003] Traditional test equipment usually uses a base or platform to fix the pump. The base or platform is usually made of a strong material, such as steel or concrete, to provide stable support. The pump is firmly fixed by bolts or clamps installed on the base to ensure that it does not move or vibrate during operation. This fixing method helps to ensure the accuracy and reliability of the test, while protecting the pump and test equipment from unnecessary damage.
[0004] However, the fixing method of the traditional test device is relatively simple in structure and only relies on bolts or clamps for fixing, which may lead to insufficient or unstable fixing. In addition, this fixing method requires cumbersome installation and disassembly processes, and may require multiple adjustments and corrections to ensure the correct positioning and stability of the pump, which increases the complexity and time-consuming of the test operation. At the same time, the structure of the base or platform may have defects or wear, affecting its support and fixing effect on the pump, which is easy to cause unexpected situations or damage to the pump during the test.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a marine pump performance test device for comprehensive reliability test, including a test bench 1, a support plate 2 is fixedly connected to the top of the test bench 1, a first guide rail 3 is fixedly connected to one side of the support plate 2, a support block 4 is slidably connected to the outer wall of the first guide rail 3, a second guide rail 5 is fixedly connected to one side of the support plate 2, a slider 6 is slidably connected to the outer wall of the second guide rail 5, a connection block 7 is rotatably connected to one side of the support block 4, one side of the connection block 7 is rotatably connected to one side of the slider 6, a fixed plate 10 is fixedly connected to one side of the support block 4, and a fixed plate 10 is fixedly connected to one side of the support block 4. A support column 12 is slidably connected inside the fixed plate 10, and a fixed block 11 is fixedly connected to the bottom end of the support column 12, and one side of the fixed block 11 is fixedly connected to one side of the support plate 2. A first spring 13 is sleeved on the outer wall of the support column 12, and one end of the first spring 13 is fixedly connected to the bottom of the fixed plate 10, and the other end of the first spring 13 is fixedly connected to the top of the fixed block 11. A clamping assembly is provided on one side of the slider 6, and the clamping assembly includes a connecting plate 8 and a clamping block 9, one side of the connecting plate 8 is fixedly connected to one side of the slider 6, and one side of the clamping block 9 is fixedly connected to one side of the connecting plate 8.
[0025] Specifically, when using the test device, first, by pressing the support block 4, the support block 4 is forced to slide on the outer wall of the first guide rail 3, and at the same time, the support block 4 is forced to drive the fixed plate 10 fixedly connected on one side to slide on the outer wall of the support column 12, and the fixed plate 10 is forced to squeeze the first spring 13 fixedly connected at the bottom to shrink, and at the same time, the support block 4 also drives the connecting block 7 rotatably connected on one side to rotate, and the connecting block 7 is forced to drive the sliding block 6 rotatably connected on one side to slide on the outer wall of the second guide rail 5, and the second guide rail 5 is forced to drive the connecting plate 8 fixedly connected on one side to move, and the connecting plate 8 is forced to drive the clamping block 9 fixedly connected on one side to move, so that the clamping block 9 is opened outward, and the pump to be tested is placed between the clamping blocks 9. Then, the support block 4 is released, and at the same time, the first spring 13 unloads the force and rebounds, thereby driving the fixed plate 10 to reset, so that the clamping block 9 is forced to move to the outer wall of the pump to fix it, so as to achieve the effect of quickly fixing the pump, and realize the rapid and stable fixation of the pump, and improve the test efficiency and operation convenience.
[0026] Reference Figure 3 and Figure 4A pump body 14 is provided on the top of the test bench 1, and a first connecting pipe 15 is fixedly connected to the input end of the pump body 14. A test tube 16 is fixedly connected inside the test bench 1, and a second connecting pipe 17 is fixedly connected to one end of the test tube 16. A first connecting head 19 is slidably connected inside the first connecting pipe 15, and a second spring 20 is provided at one end of the first connecting head 19. One end of the second spring 20 is fixedly connected to the inside of the first connecting pipe 15, and a second connecting head 21 is slidably connected inside the second connecting pipe 17. A third spring 22 is provided at one end of the second connecting head 21, and one end of the third spring 22 is fixedly connected to the inside of the second connecting pipe 17. A retaining ring 18 is slidably connected to the outer wall of the second connecting pipe 17. A fourth spring 25 is sleeved on the outer wall of the second connecting pipe 17, and one end of the fourth spring 25 is fixedly connected to the inside of the retaining ring 18.
[0027] Specifically, when the pump and the pipeline need to be connected, first, the clamp ring 18 on the outer wall of the second connecting tube 17 is pulled to trigger the contraction of the internal fourth spring 25, and then the second connecting tube 17 fixedly connected to one end of the test tube 16 is inserted into the outer wall of the first connecting tube 15 connected to the input end of the pump body 14, triggering a series of interactions between internal components. The first connector 19 inside the first connecting tube 15 contacts the second connector 21 inside the second connecting tube 17, causing the second spring 20 and the third spring 22 to contract simultaneously, thereby enhancing the stability of the connection.
[0028] Reference Figure 3 and Figure 4 A sealing ring 23 is disposed on the outer wall of the second connecting tube 17 , and a ball bearing 24 is disposed inside the second connecting tube 17 .
[0029] Specifically, during this process, the ball 24 inside the second connecting tube 17 contacts the outer wall of the first connecting tube 15, making the connection tighter. Finally, after moving to the appropriate position, the snap ring 18 is released, so that the fourth spring 25 rebounds and drives the snap ring 18 to reset, ensuring that the snap ring 18 applies sufficient extrusion force to the ball 24, so that it is stuck on the outer wall of the first connecting tube 15, thereby completing the fixed connection. At the same time, the sealing ring 23 inside the second connecting tube 17 is also contracted by pressure, ensuring the sealing of the connection, so that the connection between the pump and the pipeline is stable and reliable.
[0030] Working principle: When using the test device, first press the support block 4 to make it slide on the outer wall of the first guide rail 3 under force, and at the same time, the support block 4 is forced to drive the fixed plate 10 fixedly connected on one side to slide on the outer wall of the support column 12, and the fixed plate 10 is forced to squeeze the first spring 13 fixedly connected at the bottom to shrink, and at the same time, the support block 4 also drives the connecting block 7 rotatably connected on one side to rotate, and the connecting block 7 is forced to drive the sliding block 6 rotatably connected on one side to slide on the outer wall of the second guide rail 5, and the second guide rail 5 is forced to drive the connecting plate 8 fixedly connected on one side to move, and the connecting plate 8 is forced to drive the clamping block 9 fixedly connected on one side to move, so that the clamping block 9 is opened outward, and the pump to be tested is placed between the clamping blocks 9, and then the support block 4 is released, and at the same time, the first spring 13 unloads the force and rebounds, thereby driving the fixed plate 10 to reset, so that the clamping block 9 is forced to move to the outer wall of the pump to fix it, thereby achieving the effect of quickly fixing the pump. When it is necessary to connect the pump and the pipeline, first pull the clamping ring 18 slidably connected to the outer wall of the second connecting pipe 17, and the clamping ring 1 8 is forced to squeeze the fourth spring 25 fixedly connected inside to shrink, and then the second connecting tube 17 fixedly connected at one end of the test tube 16 is inserted into the outer wall of the first connecting tube 15 connected to the input end of the pump body 14. At this time, the first connecting head 19 slidably connected inside the first connecting tube 15 contacts the second connecting head 21 slidably connected inside the second connecting tube 17, and the first connecting head 19 is forced to squeeze the second spring 20 fixedly connected at one end to shrink, and at the same time, the second connecting head 21 is forced to squeeze the third spring 22 fixedly connected at one end to shrink. During this movement, the ball 24 arranged inside the second connecting tube 17 contacts the outer wall of the first connecting tube 15 and then shrinks. When it moves to a certain position, the clamping ring 18 is released at this time, and the fourth spring 25 unloads the force and rebounds, thereby driving the clamping ring 18 to reset, so that the clamping ring 18 applies an extrusion force to the ball 24, so that it is stuck on the outer wall of the first connecting tube 15 to fix it, and at the same time, the sealing ring 23 arranged inside the second connecting tube 17 shrinks under pressure to seal, thereby achieving the effect of quickly connecting the pump and the pipeline firmly.
