In actual operation, pipelines need to withstand various loads from internal fluid pressure and external environmental pressure. If the pipeline's pressure resistance performance does not meet the standards, it may cause serious problems such as leakage and bursting. In order to ensure the safe and stable operation of the drainage system, it is crucial to develop a high-precision and high-efficiency pressure resistance testing device for drainage pumps and drainage pipelines. Current traditional testing methods have shortcomings such as low testing efficiency and poor data accuracy, which make it difficult to meet the accurate testing needs of pipeline pressure resistance performance under complex working conditions. There is an urgent need to innovate testing technologies and devices.

[0003] To address the aforementioned issues, existing patents have provided solutions. However, existing pressure testing devices for drainage pumps and pipelines typically lack accurate simulation of changes in internal water pressure under different operating conditions. This makes it difficult to comprehensively and realistically reproduce the internal pressure environment of drainage pipelines during actual operation, leading to discrepancies between test results and actual usage. This affects the accurate assessment of pipeline pressure resistance performance and makes it difficult to test pipeline pressure resistance under diverse conditions. Consequently, it is impossible to fully grasp the pipeline's pressure resistance capacity during actual operation, impacting the comprehensiveness of the test data.

[0024] 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.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A pressure resistance testing device for a drainage pump and drainage pipe includes a base 1, a test bench 2 fixedly connected to the top of the base 1, a simulation component 4 arranged on the right side of the test bench 2, and a testing component 5 arranged on the top of the test bench 2.

[0027] The simulation component 4 includes a metering pump 401 fixedly connected to the top of the test bench 2. The inlet end of the metering pump 401 is connected to a delivery pipe 402. A water tank 403 is fixedly connected to the top of the base 1. The delivery pipe 402 is connected to the water tank 403. The output end of the metering pump 401 is connected to a mounting base 404. A valve 405 is provided on the outside of the mounting base 404. A flow detector 406 is provided on the top of the mounting base 404. A connecting flange pipe 407 is fixedly connected to the left side of the mounting base 404. A pressure sensor 408 is provided on the top of the connecting flange pipe 407.

[0028] In this embodiment: By opening the water inlet at the top of the water tank 403, an appropriate amount of water is injected into the water tank 403 to meet the requirements of the testing process. Then, one end of the drainage pipe of the drainage pump to be tested is tightly connected to the connecting flange pipe 407. Next, the metering pump 401 is started. After the metering pump 401 starts working, it draws water from the water tank 403 through the delivery pipe 402 and delivers the water to the mounting base 404. Then, the flow rate and pressure of the water are controlled by adjusting the opening of the valve 405. The flow detector 406 monitors the flow rate of the water in real time and transmits the monitoring data to the data display device or control system. At the same time, the pressure sensor 408 continuously monitors the pressure changes in the connecting flange pipe 407 and feeds back the pressure data to the operator. The operator can further adjust the opening of the valve 405 according to the real-time data of flow rate and pressure so that the pressure and flow rate in the pipe reach the values ​​required for testing. During the testing process, in order to more comprehensively evaluate the pressure resistance performance of the drainage pipe, the opening of the valve 405 can be changed periodically according to a preset program to simulate the pressure fluctuations that the pipe experiences during long-term operation.

[0029] Specifically, such as Figure 3 As shown, the detection component 5 includes a hydraulic cylinder 501 fixedly connected to the top of the test bench 2. The output end of the hydraulic cylinder 501 is fixedly connected to a top plate 502. A limiting slide rod 503 is fixedly connected to the top of the top plate 502. The limiting slide rod 503 is slidably connected to the test bench 2. A connecting support rod 504 is slidably connected inside the top plate 502.

[0030] Specifically, such as Figure 3 As shown, an arc-shaped pressure plate 505 is fixedly connected to the bottom of the connecting rod 504, and a buffer spring 506 is provided on the outside of the connecting rod 504. The buffer spring 506 is located at the bottom of the top plate 502.

[0031] Specifically, such as Figure 3As shown, a test base 507 is fixedly connected inside the test bench 2. The test base 507 is located at the bottom of the arc-shaped pressure plate 505, and an anti-slip pad 508 is glued to the top of the test base 507.

[0032] In this embodiment: Before testing, the drainage pipe to be tested is placed on the test base 507. The anti-slip pad 508 increases the friction between the pipe and the test base 507, preventing displacement of the pipe during testing and ensuring testing stability. After the pipe is in place, the hydraulic cylinder 501 is activated, its output end pushing the top plate 502 along the limiting slide rod 503. The limiting slide rod 503 acts as a guide, slidingly connected to the test platform 2, ensuring the top plate 502 rises or falls smoothly, avoiding deviation, and ensuring even pressure distribution on the pipe. During the movement of the top plate 502, the connecting support rod 504 also moves synchronously with the top plate 502. Because the connecting support rod 504 is slidably connected inside the top plate 502, it will move along the top plate 502... As the top plate 502 descends, the arc-shaped pressure plate 505 at the bottom of the connecting rod 504 gradually approaches the drainage pipe. The special shape design of the arc-shaped pressure plate 505 allows it to better fit the pipe surface, ensuring that the pressure is applied evenly to the pipe. When the arc-shaped pressure plate 505 contacts the pipe, the hydraulic cylinder 501 continues to push the top plate 502, and the pressure begins to gradually increase. At this time, the buffer spring 506 can buffer the pressure change, preventing the pressure from being too high at once and causing damage to the pipe. At the same time, it makes the pressure application more stable, simulating the characteristics of slow changes in external pressure in actual use. During the continuous pressure application by the hydraulic cylinder 501, the operator can observe the condition of the drainage pipe and check for deformation, cracks, etc., in order to evaluate the pressure resistance of the pipe.

[0033] Specifically, such as Figure 5 As shown, a limiting base 6 is fixedly connected to the left side of the test bench 2. A fixing rod 7 is threadedly connected to the top of the limiting base 6. A limiting top seat 8 is rotatably connected to the inner side of the fixing rod 7. The limiting top seat 8 is located on the top of the limiting base 6. Pressure sensing plates 9 are provided inside both the limiting base 6 and the limiting top seat 8.

[0034] Specifically, such as Figure 4 As shown, a pipe placement seat 10 is fixedly connected to the base of the test bench 2, and a water collection tank 11 is fixedly connected to the bottom of the pipe placement seat 10. A connecting pipe 12 is connected to the bottom of the water collection tank 11, and the connecting pipe 12 is connected to the water tank 403.

[0035] In this embodiment: by setting a limiting base 6, a fixing rod 7, a limiting top seat 8, and a pressure sensing plate 9, when performing pressure resistance testing on the drainage pump drainage pipe, first connect one end of the pipe to be tested to the connecting flange pipe 407. Then, place the left side of the pipe between the limiting base 6 and the limiting top seat 8. By rotating the fixing rod 7, adjust the position of the limiting top seat 8 to make it fit tightly against the pipe. During the entire testing process, when the pipe is subjected to internal water pressure and external simulated pressure, its pressure sensing plate 9 can acquire the pressure data on the side of the pipe in real time. This data, along with the internal water pressure data and the external simulated pressure data, is then compared with the pressure data inside the pipe. The combination of these features allows operators to gain a more comprehensive understanding of the pipeline's condition under complex stress conditions. By setting up a pipeline placement seat 10, a water collection tank 11, and a connecting pipe 12, when placing the drainage pipeline to be tested, one end of it is connected to the connecting flange pipe 407, and then the pipeline is placed on the pipeline placement seat 10. During the pressure test, if the pipeline leaks, the leaked water will flow along the pipeline into the water collection tank 11 at the bottom of the pipeline placement seat 10. After the water collection tank 11 collects the leaked water, it is transported back to the water tank 403 through the connecting pipe 12 at the bottom, thus realizing the recycling of water resources.

[0036] Specifically, such as Figure 4 As shown, a top cover 13 is slidably connected to the top of the water tank 403, and a hydraulic gauge 14 is provided on the top of the top cover 13.

[0037] Specifically, such as Figure 1 As shown, a cushioning pad 3 is bonded to the bottom of the base 1. The cushioning pad 3 is made of rubber.

[0038] In this embodiment: By setting a top cover 13 and a hydraulic gauge 14, before testing, the water inlet on the top of the water tank 403 is opened, and an appropriate amount of water is injected into the water tank 403. During the testing process, the top cover 13 is closed to prevent external debris from entering the interior of the water tank 403. The hydraulic gauge 14 on the top monitors the water pressure changes in the water tank 403 in real time. By observing the data of the hydraulic gauge 14, the operator can promptly detect abnormal water pressure in the water tank 403, ensuring the stability of the water pressure drawn by the metering pump 401, thereby ensuring the accuracy of the simulated water pressure inside the pipeline and improving the accuracy and reliability of the entire pressure test. By setting a buffer pad 3, when the hydraulic cylinder 501 of the testing component 5 applies pressure to the pipeline, and when the water pressure changes inside the pipeline causes vibration, the buffer pad 3 will absorb these vibrations and impacts to ensure the stable operation of each component during the testing process and improve the accuracy and stability of the test data.

[0039] Working Principle: When conducting pressure testing on drainage pipes, first connect one end of the drainage pipe to be tested to the connecting flange pipe 407, ensuring a tight connection to prevent leakage during the test. Place the other end stably on the pipe placement seat 10 to ensure the pipe is in a horizontal and stable state. Place the middle part on the test base 507 to provide support for the pipe. Then, fix the left side of the pipe using the limiting base 6 and the limiting top seat 8 to ensure that the pipe will not shift during the test and to ensure the accuracy of the test results. After the preparation is completed, start the metering pump 401. The metering pump 401 draws water from the water tank 403, and the water flows along the delivery pipe 402. The water flows through mounting base 404 and reaches valve 405. Valve 405 can flexibly adjust the flow rate and pressure of the water according to actual testing needs, thereby simulating the internal water pressure borne by the drainage pipe under different working conditions. The water then passes through flow detector 406, which can monitor the flow rate data of the water in real time and feed this data back to the operator so as to grasp the water flow situation in a timely manner. Subsequently, the water flows into connecting flange pipe 407 and finally enters the drainage pipe to be tested, so that the inside of the pipe is subjected to water pressure. At this time, pressure sensor 408 begins to play its role. It continuously monitors the changes in water pressure inside the pipe and transmits the data to the data sensor. According to the data acquisition equipment, while conducting a water pressure test inside the pipeline, hydraulic cylinder 501 is activated. Hydraulic cylinder 501 begins to work, pushing the top plate 502 downwards along the limiting slide rod 503. The limiting slide rod 503 acts as a guide, ensuring the top plate 502 descends smoothly and avoids deviation, thus ensuring uniform pressure application. During the descent of the top plate 502, the connecting support rod 504 drives the arc-shaped pressure plate 505 to move synchronously. The special shape of the arc-shaped pressure plate 505 fits well with the drainage pipe, ensuring uniform pressure distribution on the pipe surface. When the arc-shaped pressure plate 505 contacts the drainage pipe, the pressure gradually increases as hydraulic cylinder 501 continues to push. At this point, the buffer spring... 506 can buffer pressure, preventing damage to the pipeline from excessive pressure in an instant, and can also make the pressure application more stable, simulating the characteristics of external pressure changes in actual use. Throughout the testing process, the anti-slip pad 508 is in contact with the test pipeline to ensure the stability of the testing process. Through the continuous pressure of the hydraulic cylinder 501, the pressure resistance performance of the drainage pipeline under the pressure of the arc-shaped pressure plate 505 is observed, such as whether deformation or cracks occur, thereby evaluating its pressure resistance performance. Finally, by combining the data transmitted by the pressure sensor 408 and the flow detector 406, the pressure resistance performance of the pipeline under different pressure conditions is analyzed to determine whether the pipeline can withstand the specified pressure and whether there is a risk of leakage.

[0040] The above are merely preferred embodiments of the present utility model and are 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.
