Abstract
Description
Technical Field
[0001] This utility model relates to a flexible flow-blocking device, specifically a flexible flow-blocking device capable of adjusting the flow-blocking height, belonging to the technical field of flow-blocking devices. Background Technology
[0002] A flexible flow interception device is an engineering device made of flexible materials that can flexibly adapt to changes in water flow to achieve water flow interception. The core technology of a flexible flow interception device lies in its unique structural design and material selection. It utilizes the deformability of flexible materials to achieve water flow interception and diversion through external control. When flow interception is required, the flexible material deforms to form a sealed space, cutting off the flow path of the fluid.
[0003] In existing technologies, such as the flexible flow-blocking device disclosed in CN212959970U, there is an inlet and outlet, an outer shell, and a rubber sleeve. The outer shell is disposed outside the rubber sleeve and is sealed to the rubber sleeve. A pressurization chamber is formed between the outer shell and the rubber sleeve. The inlet and outlet communicate with the pressurization chamber. The rubber sleeve has a through-flow channel. A first sealing element is provided on the inner wall of the rubber sleeve, located at the closed position of the rubber sleeve. A second sealing element is also provided on the inner wall of the first sealing element, located on the highest protrusion of the first sealing element at the closed position of the rubber sleeve. This device can achieve complete shut-off and zero leakage of the flow channel under relatively low pressure, and the flexible flow-blocking device can be opened or closed quickly.
[0004] While the above-mentioned technical solutions can achieve complete shut-off and zero leakage of the flow channel under low pressure and the flexible shut-off device can open or close quickly, the opening degree of the pneumatic clamp valve is controlled by controlling the pressure. However, since the entire clamp rubber tube is in a deformed state under air pressure, the shut-off height cannot be controlled. Therefore, a flexible shut-off device that can adjust the shut-off height is provided to overcome the above-mentioned defects. Utility Model Content
[0005] This invention addresses the problem that while controlling the opening of a pneumatic clamp valve by controlling the pressure level can control the flow angle, the entire rubber tube of the clamp is in a deformed state under air pressure, making it impossible to control the flow angle. Therefore, this invention provides a flexible flow angle control device capable of adjusting the flow angle.
[0006] The present invention achieves the above objectives through the following technical solution: a flexible interception device capable of adjusting the interception height, comprising a device housing, an adjustment mechanism for adjusting the interception height provided on the outer surface of the device housing, and a fixing mechanism for fixing the device provided inside both ends of the device housing.
[0007] The regulating mechanism includes an regulating component, which is fixed to the outer surface of the device housing. An air inlet is provided at the upper end of the regulating component. Four connecting pipes are symmetrically fixed inside the regulating component. Solenoid valves are installed on the outer surface of each of the four connecting pipes. Pressure sensors are fixed on the side walls of each of the four connecting pipes. Four high-pressure airbags that are interconnected with the connecting pipes are symmetrically fixed inside the device housing.
[0008] Preferably, a first connector is connected to one end of the device housing.
[0009] Preferably, the other end of the device housing is connected to a second connector, and both the second connector and the first connector have four symmetrical fixing holes inside.
[0010] Preferably, a support leg is fixed to the lower surface of the device housing.
[0011] Preferably, the fixing mechanism includes two connecting grooves, which are respectively opened inside the two ends of the device housing.
[0012] Preferably, both connecting slots have sliding limit blocks inside them, and one side of each limit block has an adjusting plate that is fixedly connected to the first connecting member.
[0013] Preferably, the outer wall of the device housing is fitted with two fixing bolts that abut against the outer surface of the adjusting plate.
[0014] The beneficial effects of this utility model are:
[0015] 1) The pressure sensor can detect the pressure inside the high-pressure airbag. When the throttling height needs to be adjusted, the solenoid valves on the two connecting pipes can be opened separately to cause the two high-pressure airbags at the lower end of the device shell to expand. The pressure sensor detects the pressure and sends it to the microcontroller via the data line for calculation. The microcontroller calculates the expansion height of the high-pressure airbag, thereby achieving the function of adjusting the throttling height.
[0016] 2) Compressed air is delivered to the regulating component. The solenoid valves on the four connecting pipes are normally closed. When the solenoid valves open, the compressed air can enter the four high-pressure airbags through the four connecting pipes, causing the high-pressure airbags to expand. After the four high-pressure airbags expand, they fit tightly together, thereby blocking the water flow. Attached Figure Description

[0022] 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.
[0023] Example 1, as Figures 1 to 4 As shown, a flexible flow-blocking device capable of adjusting the flow-blocking height includes a device housing 1. The outer surface of the device housing 1 is provided with an adjustment mechanism for adjusting the flow-blocking height, and the interior of both ends of the device housing 1 is provided with a fixing mechanism for fixing the device.
[0024] The adjustment mechanism includes an adjustment component 2, which is fixed to the outer surface of the device housing 1. An air inlet 21 is provided at the upper end of the adjustment component 2. Four connecting pipes 22 are symmetrically fixed inside the adjustment component 2. Solenoid valves 23 are installed on the outer surface of each of the four connecting pipes 22, and pressure sensors 24 are fixed to the side walls of each of the four connecting pipes 22. Four high-pressure airbags 25, interconnected with the connecting pipes 22, are symmetrically fixed inside the device housing 1. A first connecting component 3 is connected to one end of the device housing 1, and a second connecting component 4 is connected to the other end. Four fixing holes 5 are symmetrically provided inside both the second connecting component 4 and the first connecting component 3. A support leg 6 is fixed to the lower surface of the device housing 1. The air inlet 21 on the adjustment component 2 is connected to an air compression device via a pipe. (The last sentence appears to be incomplete and possibly refers to a different device.) During flow, compressed air is delivered to the regulating component 2. The solenoid valves 23 on the four connecting pipes 22 are normally closed. At this time, the solenoid valves 23 open, allowing compressed air to enter the four high-pressure airbags 25 through the four connecting pipes 22 respectively, causing the high-pressure airbags 25 to expand. After the four high-pressure airbags 25 expand, they fit tightly together, thereby blocking the water flow. The pressure sensor 24 can detect the pressure inside the high-pressure airbags 25. When it is necessary to adjust the blocking height, the solenoid valves 23 on two connecting pipes 22 can be opened individually, causing the two high-pressure airbags 25 at the lower end of the device housing 1 to expand. The pressure sensor 24 detects the pressure and sends it to the microcontroller via the data line for calculation, calculating the expansion height of the high-pressure airbags 25, thereby achieving the function of adjusting the blocking height.
[0025] Example 2: In addition to all the technical features in Example 1, this example also includes: a fixing mechanism comprising two connecting grooves 7, each located inside the two ends of the device housing 1. Limiting blocks 72 are slidably connected inside both connecting grooves 7. An adjusting plate 71, fixedly connected to the first connecting member 3, is fixed to one side of each limiting block 72. Two fixing bolts 73, abutting against the outer surface of the adjusting plate 71, are installed on the outer wall of the device housing 1. Through the first connecting member 3 and the second connecting member 4 at both ends of the device housing 1, bolts can be used to connect pipes inside and outside the fixing holes 5, thus completing the assembly. When the device length is too short to complete the connection, the fixing bolts 73 on the device housing 1 can be loosened, thereby releasing the fixing of the adjusting plate 71. With the cooperation of the connecting grooves 7 and the limiting blocks 72, the first connecting member 3 or the second connecting member 4 can be pulled to move, thereby adjusting the overall length of the device. After adjustment, the fixing bolts 73 are tightened to fix the adjusting plate 71, preventing accidental movement. The supporting legs 6 ensure the stability of the device.
[0026] Before using the flexible flow interceptor, the device must be assembled and fixed. Using the first connector 3 and the second connector 4 at both ends of the device housing 1, bolts can be passed through the fixing holes 5 to connect the pipes inside and outside, thus completing the assembly. Sealing rings can be installed at the connections between the first connector 3, the second connector 4, and the pipes to achieve a seal. When the device is too short to complete the connection, the fixing bolts 73 on the device housing 1 can be loosened to release the fixing of the adjusting plate 71. With the cooperation of the connecting groove 7 and the limiting block 72, the first connector 3 or the second connector 4 can be moved, thereby adjusting the overall length of the device. After adjustment, the fixing bolts 73 are tightened to fix the adjusting plate 71, preventing accidental movement. The supporting legs 6 ensure the stability of the device. The adjusting member 2 is equipped with an inlet... The air inlet 21 is connected to the air compression equipment via a pipe. When flow throttling is required, compressed air is delivered to the regulating component 2. The solenoid valves 23 on the four connecting pipes 22 are normally closed. When the solenoid valves 23 open, the compressed air can enter the four high-pressure airbags 25 through the four connecting pipes 22, causing the high-pressure airbags 25 to expand. After the four high-pressure airbags 25 expand, they fit tightly together, thereby throttling the water flow. The pressure sensor 24 can detect the pressure inside the high-pressure airbags 25. When the flow throttling height needs to be adjusted, the solenoid valves 23 on two connecting pipes 22 can be opened individually, causing the two high-pressure airbags 25 at the lower end of the device housing 1 to expand. The pressure sensor 24 detects the pressure and sends it to the microcontroller via a data cable for calculation. The microcontroller calculates the expansion height of the high-pressure airbags 25, thereby achieving the function of adjusting the flow throttling height.
