[0002] In the maintenance and management of urban stormwater drainage systems, it is necessary to regularly test the drainage capacity of the network to ensure that it can drain water normally during rainfall and prevent urban flooding. Currently, when testing the drainage capacity of stormwater drainage systems, it is usually necessary to use testing equipment to measure parameters such as the flow rate of the stormwater pipes to be tested. However, existing testing equipment has certain shortcomings in use. On the one hand, the fixing effect on the rainwater pipes to be tested is poor. During the testing process, the rainwater pipes are prone to shaking or displacement, which affects the accuracy of the test data. On the other hand, most existing fixing devices cannot be flexibly adjusted according to the actual size of the rainwater pipes, resulting in a narrow range of applications. Furthermore, during the testing process, it is difficult to conveniently adjust the angle of the rainwater pipes, which hinders the precise docking of the testing components with the rainwater pipes and reduces testing efficiency.

[0003] To address this problem, the present invention provides a fixing device for rainwater pipe network discharge detection equipment. Utility Model Content

[0018] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] Reference Figures 1 to 4 This application provides a fixing device for a rainwater pipe network discharge detection equipment, including a rainwater pipe 1 to be tested and a workbench 4. A clamping component 2 is provided on the top of the workbench 4 for stably clamping and fixing the rainwater pipe 1 to be tested. A detection component 3 is provided on the outside of the clamping component 2 for detecting the discharge status of the rainwater pipe 1 to be tested. A data processing and control device 5 is fixedly installed on the top of the workbench 4 for receiving the detection data transmitted by the detection component 3 and controlling the operation of the clamping component 2 and the detection component 3. The clamping assembly 2 includes an outer frame 22, and two sliders 24 are slidably connected inside the outer frame 22. A clamping plate 21 is fixedly installed in front of each of the two sliders 24. An arc-shaped groove is opened on the opposite side of the upper and lower clamping plates 21. The rainwater pipe 1 to be tested is located between the upper and lower arc-shaped grooves of the clamping plate 21. The arc of the arc-shaped groove is the same as the arc of the rainwater pipe 1 to be tested. The clamping stability of the rainwater pipe 1 to be tested is improved by the fit between the arc-shaped groove and the rainwater pipe 1 to be tested. A self-locking reducer 210 is fixedly installed on the top of the workbench 4. An adjusting rod 29 is fixedly installed on the output end of the self-locking reducer 210. A rotating disk 27 is fixedly installed on the front of the adjusting rod 29. The rotating disk 27 is fixedly installed on the back of the outer frame 22. The self-locking reducer 210 drives the adjusting rod 29 to rotate, which in turn drives the rotating disk 27 and the outer frame 22 to rotate, thereby adjusting the angle of the rainwater pipe 1 to be tested. The self-locking reducer 210 can self-lock after adjustment to ensure the stability of the angle of the rainwater pipe 1 to be tested. A support plate 28 is fixedly installed on the top of the workbench 4. An adjusting rod 29 is rotatably connected inside the support plate 28. The support plate 28 provides support for the adjusting rod 29, improving the stability of the adjusting rod 29 when it rotates. A servo motor 211 is fixedly installed on the side of the self-locking reducer 210. The output end of the servo motor 211 is fixedly connected to the input end of the self-locking reducer 210. The servo motor 211 is electrically connected to the data processing and control device 5. The operator can control the start, stop and speed of the servo motor 211 through the data processing and control device 5, thereby precisely controlling the angle adjustment of the rainwater pipe 1 to be tested. The outer frame 22 is internally connected to a screw 23 with different thread directions on both sides of the center of the screw 23. Two sliders 24 are screwed onto the outer sides of the threads of the screw 23 with different thread directions. When the screw 23 rotates, the two sliders 24 can move towards or away from each other along the screw 23, thereby driving the upper and lower clamping plates 21 to move closer or further apart, realizing the clamping and fixing of rainwater pipes 1 of different diameters to be tested, and expanding the applicability of the device. The thread lead angle of the screw 23 is less than the equivalent friction angle, so the screw 23 has a self-locking function, preventing the sliders 24 from moving on their own during the clamping process and ensuring the stability of the clamping. The outer side of the screw 23 is coated with a lubricating grease with strong adhesion, anti-leakage, wear resistance and anti-pollution, which reduces the friction between the screw 23 and the sliders 24, improves the service life of the screw 23, and ensures the smooth movement of the sliders 24. A rotating rod 25 is rotatably connected to the top of the outer frame 22. A knob 26 is fixedly installed on the top of the rotating rod 25. The bottom of the rotating rod 25 moves through the interior of the outer frame 22 and is fixedly connected to the screw 23. The operator can rotate the knob 26 to drive the rotating rod 25 and the screw 23 to rotate, thereby adjusting the spacing of the clamping plate 21. The operation is convenient. The detection component 3 includes an electromagnetic flow meter 31, which is fixedly installed on the left end of the rainwater pipe 1 to be tested. A water outlet pipe 32 is fixedly installed on the left side of the electromagnetic flow meter 31. The water outlet pipe 32 and the rainwater pipe 1 to be tested are interconnected through the electromagnetic flow meter 31. The electromagnetic flow meter 31 is electrically connected to the data processing and control device 5. The electromagnetic flow meter 31 can detect the flow rate of rainwater in the rainwater pipe 1 to be tested in real time and transmit the detected flow data to the data processing and control device 5, which then analyzes and processes the data. The detection component 3 also includes a servo water pump 34. A water inlet hose 33 is fixedly installed between the outlet of the servo water pump 34 and the rainwater pipe 1 to be tested. The water inlet hose 33 connects the rainwater pipe 1 to be tested and the servo water pump 34. The inlet of the servo water pump 34 is connected to an external water supply pipe. The servo water pump 34 is electrically connected to the data processing and control device 5. The operator can control the start and stop of the servo water pump 34 and the water output through the data processing and control device 5 to deliver water of different flow rates into the rainwater pipe 1 to be tested, simulating the discharge of the rainwater pipe network under different rainfall intensities, so as to comprehensively detect the discharge capacity of the rainwater pipe 1 to be tested.

[0020] In this device, the self-locking reducer 210 is an SA47 type worm gear self-locking reducer, suitable for a power range of 0.12kW-1.5kW; the servo motor 211 is a 130HMB series AC servo motor (380VAC, 2500 lines) from Beijing Hollysys Motor Technology Co., Ltd.; the electromagnetic flow meter 31 is an Endershaus ProlinePromagW400 electromagnetic flow meter, suitable for the water and wastewater industry; the servo pump 34 is a THM-VPS series, model VPS-1-20–PR15R / 1XTV, with a displacement of 16cc-200cc / rev and a maximum speed of 2800rpm, thereby ensuring the coordinated operation of all components and realizing the function of rainwater pipe network discharge detection.

[0021] Furthermore, all contents not described in detail in this specification are existing technologies known to those skilled in the art, and all electrical components mentioned in this document are powered by external power supply lines.

[0022] Working principle: First, the clamping assembly 2 securely fixes the rainwater pipe 1 to be tested. The operator rotates knob 26 according to the diameter of the rainwater pipe 1. Knob 26 drives rotating rod 25, which in turn drives screw 23. Because the threads on both sides of the screw 23 have different directions of rotation, the two sliders 24 move towards each other along the screw 23, thereby bringing the upper and lower clamping plates 21 closer together. The rainwater pipe 1 to be tested is placed in the arc-shaped groove of the clamping plate 21. Knob 26 is continued to be rotated until the arc-shaped groove is tightly fitted with the rainwater pipe. Furthermore, the screw 23 self-locks because its thread lead angle is less than the equivalent friction angle, preventing the sliders 24 from moving. Next, if angle adjustment is required, the servo motor 211 is started via the data processing and control device 5. The servo motor 211 drives the self-locking reducer 210, which in turn drives the adjusting rod 29 to rotate. The adjusting rod 29, via the rotating disk 27, drives the outer frame 22 and the rainwater pipe 1 to be tested to rotate. After adjusting to a suitable angle, the servo motor 211 stops, and the self-locking reducer 210 locks the angle. During the testing phase, the data processing and control device 5 controls the servo water pump 34 to start. The servo water pump 34 delivers water to the rainwater pipe 1 to be tested through the inlet hose 33, while simultaneously adjusting the water flow rate to simulate different rainfall conditions. The electromagnetic flowmeter 31 detects the flow rate in the pipe in real time and transmits the data to the data processing and control device 5. The device analyzes and processes the data, then displays the results visually for staff to assess the pipe network discharge situation. After the test is completed, the servo water pump 34 is turned off, the knob 26 is rotated in the opposite direction to loosen the clamp 21, and the rainwater pipe 1 to be tested is removed, completing the testing process.
