[0015] The present invention provides a water conservancy pipeline pressure detection device, which has the following beneficial effects: 1. The present invention has accurate water flow and water pressure monitoring capabilities: Through the combination of a variety of sensors and mechanical structures, it can measure the water pressure and flow rate in the water pipeline in real time, provide accurate monitoring data, and in combination with the output shaft, it can accurately sense the water pressure change in the water pipe. Through the rotation of the linkage secondary shaft and the linkage impeller, the water flow velocity is calculated in real time to ensure the synchronous operation of the pressure sensing element and the flow velocity detection element, realizing high-precision data monitoring. The device can continuously monitor the water flow state under different pressure and flow rate conditions in the water conservancy pipeline, providing effective data support for system optimization and maintenance.

[0016] 2. The present invention has intelligent water pressure regulation and pipe diameter change capabilities: When it detects that the water pressure is too high, the device can automatically adjust the receiving pipe diameter of the pipeline to avoid damage to the device or pipeline caused by too high water pressure. According to the real-time measured water pressure, the water flow rate is adjusted by changing the receiving pipe diameter, thereby avoiding damage to the device caused by too high water pressure. When the water pressure is too high, the water flow will drive the pressure relief float to float, triggering a warning of too high water pressure and discharging the excess water through the pressure relief float, effectively reducing the water pressure. This mechanism effectively prevents the situation of too high water pressure and ensures the safety and stability of the pipeline system.

[0017] 3. The present invention has the ability to prevent backflow and overoperation: Through an intelligent backflow restriction mechanism, it avoids the overoperation of the device when the water flow backflows. The cooperation of the ratchet and the pawl can ensure that the flow velocity detection element stops working when the water flow backflows, thereby preventing the overoperation of the device and improving the service life of the device. When the internal temperature of the device rises, the micro control pump will start to cool the internal components of the device through the U-shaped pipe system, preventing failures caused by high temperature. This design ensures that the device can operate stably under any water flow conditions, avoiding the damage caused by backflow and overoperation.

[0018] 4. The present invention has an efficient water pressure regulation and flow release mechanism: through intelligent pipe diameter adjustment and water flow control mechanisms, it can release pressure in a timely manner when the water pressure is too high, ensuring the stable operation of the system. When the water pressure is too high, the conical barrel structure helps the water flow into the U-shaped pressure application pipe, expands the pipe diameter to release pressure. When the water pressure is too high, by adjusting the linkage chuck and the embedded clamping rod, the water flow volume in the pipeline is changed, effectively reducing the water flow resistance and pressure. These designs ensure that the water pipeline can still safely and efficiently transport water under high pressure, avoiding pipeline blockage or equipment damage. BRIEF DESCRIPTION OF THE DRAWINGS

First, this water conservancy pipeline pressure detection device is used for the water pressure state of the water conservancy pipeline. The overall structure is fixed and installed by the operation frame 1, the suspension frame 2 and the top frame 3. It is docked with the water conservancy pipeline through the installed conveying steering mechanism 4 inside to receive the conveyed water and contact the pressure synchronization mechanism 5 installed inside the conveying steering mechanism 4. The traction pressure sensing element 8 and the flow velocity detection element 9 respectively installed on the suspension frame 2 and the top frame 3 are used to measure the water flow and water pressure data during the conveyance of the water conservancy pipeline. The configured pore size transformation mechanism 7 can change the receiving pipe diameter of the device according to the condition of excessive water pressure, so as to perform real-time pressure application operations.

[0023] Please refer to the appendix Figure 1 - appendix Figure 10, the conveying and steering mechanism 4 is located on the working frame 1 and is used to form a conveying pipeline for water pressure monitoring. The conveying and steering mechanism 4 includes an input tank body 41, the input tank body 41 is fixedly connected to the inside of the working frame 1, a bottom-mounted frame 42 is fixedly connected to the bottom of the input tank body 41, a heat-insulating layer 43 is embedded on the inner side wall of the input tank body 41, a three-way input pipe 44 is fixedly connected to the inside of the input tank body 41, the input end and the output end of the three-way input pipe 44 extend to both sides of the input tank body 41, and the bottom output end of the input tank body 41 extends to the inside of the bottom-mounted frame 42. A component bin 45 is fixedly connected to the top of the inner side wall of the input tank body 41 and is located above the three-way input pipe 44. The bottom output end of the three-way input pipe 44 is fixedly connected to a U-shaped pressure pipe 46. The U-shaped pressure pipe 46 extends to the outside of the working frame 1, and a conical tube extension structure is provided near the port of the three-way input pipe 44. Input folding pipes 47 are fixedly connected to both side ports of the input tank body 41. A liquid-blocking ring structure is arranged on the inner wall of the vertical pipe part of the input folding pipe 47. A pressure relief float 48 is slidably embedded in the vertical port of the U-shaped pressure pipe 46 far from the three-way input pipe 44, and a discharge pipe structure is arranged on the side wall at the same time. A discharge port is arranged on the side wall of the pressure relief float 48 facing the discharge pipe structure. The input tank body 41 included in the conveying and steering mechanism 4 is of a tank structure. The main part that is mainly connected to the three-way input pipe 44 of the water conservancy pipeline is of a three-way structure. The heat-insulating layer 43 for external cooperation and heat preservation is installed inside the input tank body 41. The two end ports are located on both sides of the input tank body 41, which are the input end and the output end respectively, and input folding pipes 47 for docking the water conservancy pipeline are added to each of them. Water from the water source enters the three-way input pipe 44 through the input folding pipe 47. The middle cross port is located in the middle of the two end ports, and the cross positions are all arc-shaped pipe guiding structures, thus forming an impact surface in a certain area. The three-way input pipe 44 is surrounded by the heat-insulating layer 43 for heat insulation to avoid the situation similar to thermal expansion and contraction caused by the external temperature. The water conveyed by the water conservancy pipeline enters the pipeline part of the middle cross port of the three-way input pipe 44 and will contact the pressure synchronization mechanism 5. When the water pressure is too high, the excessive flow will drive the contact piston 53 to drive the output shaft 51 to continuously descend, and will drive the pulling pressure sensing element 8 to calculate the data of excessive water pressure. At the same time, the contact piston 53 will enter the U-shaped pressure pipe 46 installed at the cross output port of the three-way input pipe 44. The three-way input pipe 44 will first enter the conical tube extension structure installed at the port of the U-shaped pressure pipe 46. The enlarged pipe diameter structure drives the water into the U-shaped pressure pipe 46 and continuously conveys it into the pressure relief float 48 installed at the output port of the U-shaped pressure pipe 46. The water flow drives the pressure relief float 48 to float along the inner wall of the U-shaped pressure pipe 46. After the pressure relief float 48 floats, it will form a visual warning sign for excessive water pressure, and its own discharge port will be docked with the discharge pipe structure installed on the side wall of the U-shaped pressure pipe 46 to drive the water to discharge and relieve the flow.

[0024] Please refer to the appendix Figure 1 - appendix Figure 11, the pressure synchronization mechanism 5 is located inside the working frame 1 and cooperates with the input tank body 41, the three-way input pipe 44 and the component bin 45 to contact and convert the water flow pressure. The pressure synchronization mechanism 5 includes an output shaft 51, a linkage secondary shaft 52, an embedding cylinder one 57 and a one-way limiting component. The output shaft 51 is embedded and slid on the suspension frame 2, and at the same time, both ends extend to the inside of the top frame 3 and the three-way input pipe 44 respectively. The side wall of the output shaft 51 at the position of the embedding cylinder one 57 and the aperture transformation mechanism 7 is provided with a chuck structure. The linkage secondary shaft 52 is sleeved and rotated on the surface of the output shaft 51 and extends into the three-way input pipe 44. A contact piston 53 is fixedly connected to the bottom end of the output shaft 51 extending into the three-way input pipe 44. The contact piston 53 fits on the inner wall of the output part of the three-way input pipe 44. The one-way limiting component is arranged on the inner top wall of the component bin 45. The embedding cylinder one 57 is fixedly connected to the bottom wall of the top frame 3. The chuck structure of the output shaft 51 close to the embedding cylinder one 57 is embedded into the embedding cylinder one 57, and a snap spring structure is embedded between the output shaft 51 and the inner wall of the embedding cylinder one 57. One end of the linkage secondary shaft 52 embedded into the three-way input pipe 44 is fixedly connected with a linkage impeller 58. The top end of the output shaft 51 is connected to the output end of the traction pressure sensing element 8, and the top end of the linkage secondary shaft 52 is connected to the output end of the flow rate detection element 9. The top end of the output shaft 51 is connected to the output end of the traction pressure sensing element 8, and the top end of the linkage secondary shaft 52 is connected to the output end of the flow rate detection element 9. The one-way limiting component includes a built-in frame 54, a ratchet 55 and a pawl 56. The built-in frame 54 is fixedly connected to the top of the inner side wall of the input tank body 41. The ratchet 55 is fixedly connected to the output shaft 51 and rotates with the linkage secondary shaft 52. The pawl 56 is rotatably connected to the built-in frame 54. The output end of the pawl 56 contacts and meshes with the tooth key end of the ratchet 55. A snap spring structure is arranged between the other end of the pawl 56 and the built-in frame 54. The output shaft 51 included in the pressure synchronization mechanism 5 is slidably embedded on the component bin 45 included in the conveying steering mechanism 4 and extends to the pipe section at the middle cross port of the three-way input pipe 44. At the same time, the contact piston 53 installed at the bottom end is suspended and fits on the inner wall of the middle cross port of the three-way input pipe 44. The top end of the output shaft 51 extends into the top frame 3 and is docked with the traction pressure sensing element 8 installed in the top frame 3. At the same time, the output shaft 51 passes through the embedding cylinder one 57 installed at the bottom wall of the top frame 3, and its chuck structure fits with the snap spring structure embedded in the inner wall of the embedding cylinder one 57, so that the output shaft 51 can be reset through the snap spring structure without external force. The linkage secondary shaft 52 sleeved on the surface of the output shaft 51 also extends into the three-way input pipe 44, and the other end is docked with the flow rate detection element 9 installed in the suspension frame 2. When the linkage impeller 58 installed at the bottom end of the linkage secondary shaft 52 contacts the water conducted by the three-way input pipe 44, it drives the linkage secondary shaft 52 to rotate accordingly and transmits the rotation speed to the flow rate detection element 9, driving the flow rate detection element 9 to perform real-time calculation. When the continuously fed water in the three-way input pipe 44 contacts the contact piston 53, its water pressure will drive the built-in frame 54 and the output shaft 51 to descend.When the aperture conversion mechanism 7 receives the pulling force of the output shaft 51, the water pressure data is calculated in real time according to the pulling amplitude, and remotely transported through the remote transport element 10 installed in the overhead frame 3, and the linkage impeller 58 is restricted by the one-way restriction component and cannot rotate when it contacts the water flowing back from the output port end of the three-way input pipe 44. The ratchet 55 included in the one-way restriction component is installed on the linkage secondary shaft 52. When the water conservancy pipeline delivers water, the linkage impeller 58 drives the linkage secondary shaft 52 to rotate, and the ratchet 55 rotates synchronously. When the ratchet 56 installed on the built-in frame 54 engages with the ratchet 55, the ratchet 56 itself will find slight movement, and the retaining spring structure installed between the built-in frame 54 drives the ratchet 56 to always fit the ratchet 55. When the water supply stops and backflow occurs, the pawl 56 will always contact the tooth key end of the ratchet 55, thereby stopping the measurement of the flow rate detection element 9 to avoid excessive operation of the equipment during backflow. The output shaft 51 included in the pressure synchronization mechanism 5 is slidably embedded in the component bin 45 included in the conveying steering mechanism 4 and extends to the pipe section of the middle cross port of the three-way input pipe 44. At the same time, the contact piston 53 installed at the bottom end is suspended and fits on the inner wall of the middle cross port of the three-way input pipe 44, and the top end of the output shaft 51 extends into the top frame 3 and docks with the pulling pressure sensor element 8 installed in the top frame 3. At the same time, the output shaft 51 passes through the embedded cylinder 57 installed on the bottom wall of the top frame 3, and its chuck structure and the retaining spring structure embedded in the inner wall of the embedded cylinder 57 The output shaft 51 can be reset through the retaining spring structure without external force, and the linkage secondary shaft 52 sleeved on the surface of the output shaft 51 is also embedded in the three-way input pipe 44, and the other end is connected to the flow velocity detection element 9 installed in the suspension frame 2. When the linkage impeller 58 installed at the bottom end of the linkage secondary shaft 52 contacts the water conducted by the three-way input pipe 44, the linkage secondary shaft 52 is driven to rotate, and the rotation speed is transmitted to the flow velocity detection element 9, driving the flow velocity detection element 9 to perform real-time measurement. When the water flow continuously fed into the three-way input pipe 44 contacts the contact piston 53, its water pressure will drive the built-in frame 54 and the output shaft 51 to descend. When the aperture conversion mechanism 7 receives the pulling force of the output shaft 51, it will perform real-time measurement according to the pulling amplitude. The data of the water pressure is collected and remotely transported through the remote transport element 10 installed in the overhead frame 3. When the linkage impeller 58 contacts the water flowing back from the output port of the three-way input pipe 44, it will be restricted by the one-way restriction component and cannot rotate. The ratchet 55 included in the one-way restriction component is installed on the linkage secondary shaft 52. When the water conservancy pipeline delivers water, the linkage impeller 58 drives the linkage secondary shaft 52 to rotate, and the ratchet 55 rotates synchronously. When the pawl 56 installed on the built-in frame 54 is in meshing contact with the ratchet 55, the pawl 56 itself will find slight movement, and the retaining spring structure installed between the built-in frame 54 drives the pawl 56 to always fit the ratchet 55. When the water delivery stops and backflow occurs, the pawl 56 will always contact the tooth key end of the ratchet 55.Thus, the measurement of the flow rate detection element 9 is stopped to avoid excessive operation of the device during backflow.

The liquid storage tank 65 is fixedly connected to the side wall of the top-mounted rack 3. When the components inside the top-mounted rack 3 are running, the real-time cooling mechanism 6 is enabled. After the micro control pump 66 included in the real-time cooling mechanism 6 is started, the micro control pump 66 pumps the coolant stored inside the liquid storage tank 65 into the U-shaped pipe 62. The U-shaped pipe 62 is fixed inside the top-mounted rack 3 through the fixed seat 61 and is located at the center of all the components inside the top-mounted rack 3. The U-shaped pipe 62 is fixed to the side of the fixed seat 61, and the U-shaped pipe 63 is fixed to the side. The U-shaped pipe 62 and the U-shaped pipe 63 are interconnected through the added U-shaped docking pipe 64 to form a set of flat conveying pipelines. As the coolant enters the U-shaped pipe 62, the coolant will be conveyed in the flat pipelines, guiding the heat generated inside the top-mounted rack 3 into the coolant. The coolant returns to the liquid storage tank 65 along the U-shaped pipe 63. As the coolant circulates, the heat inside the top-mounted rack 3 is dissipated. When the components inside the top-mounted rack 3 are running, the real-time cooling mechanism 6 is enabled. After the micro control pump 66 included in the real-time cooling mechanism 6 is started, the micro control pump 66 pumps the coolant stored inside the liquid storage tank 65 into the U-shaped pipe 62. The U-shaped pipe 62 is fixed inside the top-mounted rack 3 through the fixed seat 61 and is located at the center of all the components inside the top-mounted rack 3. The U-shaped pipe 62 is fixed to the side of the fixed seat 61, and the U-shaped pipe 63 is fixed to the side. The U-shaped pipe 62 and the U-shaped pipe 63 are interconnected through the added U-shaped docking pipe 64 to form a set of flat conveying pipelines. As the coolant enters the U-shaped pipe 62, the coolant will be conveyed in the flat pipelines, guiding the heat generated inside the top-mounted rack 3 into the coolant. The coolant returns to the liquid storage tank 65 along the U-shaped pipe 63. As the coolant circulates, the heat inside the top-mounted rack 3 is dissipated.

[0026] Please refer to the appendix Figure 1 - appendixFigure 11 , the aperture transformation mechanism 7 is located inside the overhead rack 3. Together with the liquid blocking ring structure of the output shaft 51 and the input elbow pipe 47, it is used to expand the water flow conveying aperture under the condition of excessive water pressure. The aperture transformation mechanism 7 includes an embedded cylinder two 71 and a two-way linkage assembly. The embedded cylinder two 71 is fixedly connected to the inner bottom wall of the suspension rack 2. A linkage chuck 72 is slidably embedded in the inner wall of the embedded cylinder two 71. A snap spring structure is provided between the inner wall of the embedded cylinder two 71 and the linkage chuck 72. The two-way linkage assembly is distributed on both sides of the embedded cylinder two 71. The two-way linkage assembly includes a side lever 73 and an embedded rod 74. The side lever 73 is rotatably connected to the suspension rack 2. The embedded rod 74 is slidably embedded into the input elbow pipe 47 and extends to the vertical part of the input elbow pipe 47. A conical block structure is provided at one end of the embedded rod 74 extending into the input elbow pipe 47. One end of the side lever 73 close to the embedded rod 74 is movably located at the top end of the embedded rod 74. One end of the side lever 73 close to the linkage chuck 72 is movably connected to the side wall of the linkage chuck 72. When the water pressure is too high, the excessive flow rate will drive the contact piston 53 to drive the output shaft 51 to continuously descend. The descending output shaft 51 will drive the operation of the aperture transformation mechanism 7 through the chuck structure installed on itself. The embedded cylinder two 71 included in the aperture transformation mechanism 7 is installed in the overhead rack 3, and the linkage chuck 72 is embedded into the embedded cylinder two 71 and slides along the inner wall of the embedded cylinder two 71, and at the same time contacts the snap spring structure configured inside the embedded cylinder two 71 for reset operation. The two-way linkage assembly installed on both sides of the linkage chuck 72 can contact the input elbow pipes 47 installed at both ports of the input tank body 41. One end of the side lever 73 included in the two-way linkage assembly is rotatably installed on the overhead rack 3. While one end is slidably installed on the linkage chuck 72, the other end is slidably installed on the embedded rod 74 embedded in the input elbow pipe 47. The conical block structure configured on the embedded rod 74 is located in the area of the liquid blocking ring structure installed on the vertical pipe structure of the input elbow pipe 47. The gap area formed between the two can allow the water conservancy pipeline to send water into the input tank body 41 and the three-way input pipe 44. When the water pressure is too high, the chuck structure of the output shaft 51 itself descends and presses the linkage chuck 72 into the embedded cylinder two 71. While the side lever 73 descends with the linkage chuck 72, it pries the embedded rod 74 docked at the other end to rise. The conical block structure of the embedded rod 74 will gradually move away from the liquid blocking ring structure of the input elbow pipe 47, so that the gap area between the two expands, thereby increasing the water delivery volume of the water conservancy pipeline to release the water pressure during water flow transportation and reducing the possibility of blockage.

[0027] Working principle: First, this water conservancy pipeline pressure detection device is used for the water pressure state of the water conservancy pipeline. The overall structure is fixed and installed by the operation frame 1, the suspension frame 2, and the top frame 3. It is docked with the water conservancy pipeline through the installed conveying steering mechanism 4 inside to receive the conveyed water and contact the pressure synchronization mechanism 5 installed inside the conveying steering mechanism 4. The traction pressure sensing element 8 and the flow rate detection element 9 respectively installed on the suspension frame 2 and the top frame 3 are used to measure the water flow and water pressure data during the conveyance of the water conservancy pipeline. The configured aperture transformation mechanism 7 can change the receiving pipe diameter of the device according to the condition of excessive water pressure, so as to perform real-time pressure application operations. The input tank body 41 included in the conveying steering mechanism 4 is of a tank structure. The main part connected to the three-way input pipe 44 of the water conservancy pipeline is of a three-way structure. The external heat insulation layer 43 for heat preservation is installed inside the input tank body 41. The two end ports are located on both sides of the input tank body 41, which are the input end and the output end respectively, and each is added with an input elbow 47 for docking with the water conservancy pipeline. The water source enters the three-way input pipe 44 through the input elbow 47. The middle cross port is located in the middle of the two end ports. At the same time, the cross positions are all arc-shaped pipeline guiding structures, thus forming an impact surface in a certain area. The three-way input pipe 44 is surrounded by the heat insulation layer 43 for heat insulation, avoiding the situation similar to thermal expansion and contraction caused by the external temperature. The water conveyed by the water conservancy pipeline enters the pipeline part of the middle cross port of the three-way input pipe 44 and will contact the pressure synchronization mechanism 5. The output shaft 51 included in the pressure synchronization mechanism 5 slides and is embedded on the component bin 45 included in the conveying steering mechanism 4 and extends to the pipeline section of the middle cross port of the three-way input pipe 44 at the same time. The contact piston 53 installed at the bottom is suspended and attached to the inner wall of the middle cross port of the three-way input pipe 44. The top end of the output shaft 51 extends into the top frame 3 and is docked with the traction pressure sensing element 8 installed in the top frame 3. At the same time, the output shaft 51 passes through the embedding cylinder 1 57 installed on the bottom wall of the top frame 3, and its chuck structure fits with the snap ring structure embedded on the inner wall of the embedding cylinder 1 57, so that the output shaft 51 can be reset through the snap ring structure without external force. The linkage sub-shaft 52 sleeved on the surface of the output shaft 51 is also embedded into the three-way input pipe 44, and the other end is docked with the flow rate detection element 9 installed in the suspension frame 2. When the linkage impeller 58 installed at the bottom end of the linkage sub-shaft 52 contacts the water conducted by the three-way input pipe 44, it drives the linkage sub-shaft 52 to rotate accordingly, and transmits the rotational speed to the flow rate detection element 9, driving the flow rate detection element 9 to perform real-time calculation. The continuously fed water flow in the three-way input pipe 44, when contacting the contact piston 53, its water pressure will drive the built-in frame 54 and the output shaft 51 to descend. When the aperture transformation mechanism 7 receives the pulling force of the output shaft 51, it calculates the water pressure data in real time according to the pulling amplitude and conducts remote transmission through the remote transmission element 10 installed in the top frame 3. The linkage impeller 58 will be restricted by the one-way restriction component and cannot rotate when contacting the water flowing back at the output port end of the three-way input pipe 44.The ratchet 55 included in the one-way limiting component is installed on the linkage countershaft 52. When the water pipe is delivering water, the linkage impeller 58 drives the linkage countershaft 52 to rotate, and the ratchet 55 rotates synchronously. When the pawl 56 installed on the built-in frame 54 is in meshing contact with the ratchet 55, the pawl 56 itself will find slight movement, and the retaining spring structure installed between the built-in frame 54 drives the pawl 56 to always fit the ratchet 55. When the water delivery is stopped and backflow occurs, the pawl 56 will always contact the tooth key end of the ratchet 55, thereby stopping the measurement of the flow rate detection element 9 to avoid excessive operation of the equipment during backflow. When the internal components of the overhead frame 3 are running, the real-time cooling mechanism 6 is enabled. After the micro-control pump 66 included in the real-time cooling mechanism 6 is started, the micro-control pump 6 6 The coolant stored in the liquid storage tank 65 is pumped into the U-shaped tube 1 62, and the U-shaped tube 1 62 is fixed to the inside of the overhead rack 3 through the fixing seat 61 and is located at the center of all components in the overhead rack 3. The U-shaped tube 1 62 is fixed on the side of the fixing seat 61, and the U-shaped tube 2 63 is fixed on the side. The U-shaped tube 1 62 and the U-shaped tube 2 63 are interconnected through the installed U-shaped butt joint pipe 64 to form a group of flat conveying pipelines. As the coolant enters the U-shaped tube 1 62, the coolant will be transported in the flat pipeline to guide the heat generated inside the overhead rack 3 into the coolant. The coolant returns to the liquid storage tank 65 along the U-shaped tube 2 63. As the coolant circulates, the heat inside the overhead rack 3 is dissipated, so that the inside of the overhead rack 3 The components can operate more stably, and when the water pressure is too high, the excessive flow will drive the contact piston 53 to drive the output shaft 51 to continue to descend, and will drive the pulling pressure sensor element 8 to calculate the data of excessive water pressure, and at the same time make the contact piston 53 enter the U-shaped pressure pipe 46 installed at the cross output port of the three-way input pipe 44. The three-way input pipe 44 will first enter the conical cylinder extension structure installed at the port of the U-shaped pressure pipe 46. The enlarged pipe diameter structure drives water to enter the U-shaped pressure pipe 46 and continuously transport it to the pressure relief buoy 48 installed at the output port of the U-shaped pressure pipe 46. The water flow drives the pressure relief buoy 48 to float up along the inner wall of the U-shaped pressure pipe 46, and the pressure relief buoy 48 itself will form a visual warning mark of excessive water pressure after floating up. At the same time, its own discharge port will dock with the discharge pipe structure installed on the side wall of the U-shaped pressure tube 46 to drive the water to discharge. At the same time, the descending output shaft 51 will drive the operation of the aperture change mechanism 7 through the chuck structure installed on itself. The embedded cylinder 2 71 included in the aperture change mechanism 7 is installed in the top frame 3, and the linkage chuck 72 is embedded in the embedded cylinder 2 71 and slides along the inner wall of the embedded cylinder 2 71. At the same time, it contacts the retaining spring structure configured inside the embedded cylinder 2 71 to perform a reset operation, and the two-way linkage components installed on both sides of the linkage chuck 72 can contact the input folded tube 47 installed on the two side ports of the input tank body 41. The side pry bar 73 included in the two-way linkage component is rotatably installed on the top frame 3, and one end is slidably installed on the linkage chuck 72.The other end is slidably mounted on the embedded clamp rod 74 embedded in the input folded tube 47. The cone block structure of the embedded clamp rod 74 itself is located in the liquid blocking ring structure area installed on the vertical pipe structure of the input folded tube 47. The gap area formed between the two can be used for the water conservancy pipeline to send water into the input tank 41 and the three-way input pipe 44. When the water pressure is too high, the clamp structure of the output shaft 51 itself drops, and presses the linkage clamp 72 into the embedded cylinder 71. When the linkage clamp 72 drops, the side pry bar 73 pries the embedded clamp rod 74 at the other end to rise, and the cone block structure of the embedded clamp rod 74 will gradually move away from the liquid blocking ring structure of the input folded tube 47, so that the gap area between the two is expanded, thereby increasing the water delivery volume of the water conservancy pipeline, releasing the water pressure during water flow delivery, and reducing the possibility of blockage.
