Description

Technical Field

[0001] This utility model belongs to the field of liquid flow control technology, specifically relating to a flow control mechanism for flexible hoses and pipelines. Background Technology

[0002] In the manufacturing process of wind turbine blades, vacuum injection is a key process for forming blades and their prefabricated components. The principle of vacuum injection is to use the vacuum negative pressure in the mold cavity to draw the injection resin into the mold cavity through the pipeline.

[0003] Currently, vacuum infusion technology involves manually opening and closing valves for infusion. This manual process lacks controllability, as the operation relies on operator judgment and depends heavily on experience and focus. This can easily lead to various infusion problems, defects, increased labor and material costs, and extended production cycles. Furthermore, since the resin infusion pipelines for wind turbine blades rely on manual ball valves for flow control, and given the large number of pipelines, all of which are single-use, the flow control process is cumbersome and inconvenient, resulting in significant material waste.

[0004] In summary, there is an urgent need for a reusable flexible hose flow control mechanism that can save manual operation, avoids direct contact with liquids such as resin inside the pipe, and is reusable. Utility Model Content

[0005] The purpose of this invention is to provide a reusable flexible hose flow control mechanism that saves manual operation, does not directly contact the resin or other liquids in the pipe, and is reusable.

[0006] The above objective is achieved through the following technical solution: a flexible hose flow control mechanism, comprising a fixed base, a drive assembly, a guide assembly, and a clamping assembly. The clamping assembly includes a fixed clamp and a movable clamp. The drive assembly, the guide assembly, and the fixed clamp are fixed on the fixed base. The movable clamp is fixed at the output end of the drive assembly and is disposed opposite to the fixed clamp. The drive assembly is used to drive the movable clamp to move radially along the hose under the guidance of the guide assembly, thereby controlling the flow area of ​​the flexible hose by controlling the relative distance between the fixed clamp and the movable clamp.

[0007] The utility model can be used for the control of the liquid flow of the hose pipeline, such as the resin infusion control device in the blade manufacturing process of the wind power generation industry, or the control of the resin infusion of the glass fiber reinforced plastic forming, or the control of the liquid flow of the hose pipeline of the biological medical treatment. In the specific application process, the position of the mechanism is set, the hose is located between the fixed clamp and the movable clamp, one side of the hose abuts against the fixed clamp, the axial direction of the hose is perpendicular to the connecting line between the fixed clamp and the movable clamp, when the flow of the hose pipeline needs to be adjusted, the driving assembly drives the movable clamp to move, the fixed clamp and the movable clamp clamp the hose, the relative distance between the fixed clamp and the movable clamp is adjusted, the flow area (cross-sectional area) of the hose pipeline is changed, and the flow control of the hose pipeline and the on-off of the single fluid pipeline can be realized; the guide assembly is used for ensuring that the movable clamp only moves along the radial direction of the hose and ensuring that the operation of the whole machine is stable.

[0008] The utility model replaces the ball valve on the original infusion pipeline to control the resin infusion mode, controls the infusion flow by the clamping control of the external mechanism to change the area of the infusion section, saves the artificial operation steps, is favorable for realizing the automatic control, the external clamping mechanism does not directly contact the liquid such as resin in the pipeline, and therefore the utility model can be repeatedly used and the ball valve in the prior art mode is saved.

[0009] Further technical solutions are that the fixed seat is provided with a pipe clamp for fixing the hose. The pipe clamp is used for fixing the position of the hose, ensuring that the radial direction of the hose is consistent with the movement direction of the movable clamp, and preventing the hose from changing position greatly during clamping.

[0010] Further technical solutions are that the pipe clamp at least includes oppositely arranged first and second elastic pipe clamps, and the connecting line between the first and second elastic pipe clamps is perpendicular to the movement direction of the movable clamp. When the movable clamp is in the maximum loosening position, the connecting line between the first and second elastic pipe clamps is located between the fixed clamp and the movable clamp. In the above manner, the hose is fixed reliably and the position is well limited.

[0011] Further technical solutions are that the guide assembly includes a guide rail fixed on the fixed seat and a sliding block in sliding connection with the guide rail, and the movable clamp is fixedly connected with the sliding block.

[0012] Further, the drive assembly comprises a drive motor, the hose pipeline flow control mechanism further comprises a controller and a sensor for detecting the original position of the movable clamp, the sensor transmits a detection signal to the controller, the controller is used for sending a pulse signal and controlling the drive motor to move and recording the number of pulses to calculate the distance between the movable clamp and the original position. Of course, the sensor can also detect the original position of the slider. Since the movable clamp and the slider move synchronously, it can also be considered that the original position of the movable clamp is detected. In the specific application process, when the controller sensor detects that the slider or the movable clamp returns to the original position, the controller records this position (the position is preferably the maximum release state of the clamping assembly), and the controller controls the movement of the movable clamp based on the original position. The controller sends a pulse signal to control the movement of the drive motor and records the number of pulses. According to the number of pulse signals, the controller calculates the distance between the movable clamp and the original position, thereby feeding back the movement position of the movable clamp and further feeding back the clamping state of the hose pipeline.

[0013] Further, the drive motor is a through-type screw motor, the through-type screw motor is embedded with a nut, the nut is in transmission connection with the rotating shaft of the motor, the transmission screw rod of the through-type screw motor is in threaded connection with the nut, and the movable clamp is fixed at one end of the transmission screw rod. Specifically, the controller first takes the position detected by the sensor as the initial position (original position) of the movable clamp, then the controller transmits a certain number of pulses, the through-type screw motor receives the pulse signal, the internal nut rotates to drive the transmission screw rod to move, the nut rotates a certain number of turns n, according to the lead p of the transmission screw rod, the movable clamp moves a distance n*p, at this time the controller calculates that the distance between the movable clamp and the initial position (original position) is n*p, so that the position of the movable clamp is accurately controlled, and the distance between the movable clamp and the fixed clamp is effectively controlled to realize the hose pipeline flow control. The transmission screw rod can be a trapezoidal screw rod.

[0014] On the other hand, the nut in the through-type screw motor rotates to drive the transmission screw rod to move, the transmission screw rod drives the movable clamp to move to clamp the hose pipeline, according to the signal transmitted by the controller, after the movable clamp is moved to the position, the through-type screw motor is powered off, and there is a static torque between the transmission screw rod and the screw nut and the screw nut itself, which generates an axial self-locking force on the transmission screw rod, and according to the lead P of the transmission screw rod, the generated self-locking force is not less than 1400N. The self-locking force of this structure is the force generated by the mechanical structure, which ensures the effectiveness of the clamping force and saves the energy utilization in the mechanism.

[0015] Further, the drive motor is fixed on the fixed seat through a fixed flange. In this way, the drive motor is effectively defined to ensure the stability of the drive motor during movement.

[0016] Further technical solutions are that the fixed seat is provided with a limiting block, and the limiting block is arranged on the side of the guide rail away from the fixed clamp. In this way, the limiting block is used for limiting the sliding block, preventing the transmission lead screw from retreating too much when the clamping assembly loosens the hose pipe, and thus causing the movable clamp to hit the fixed flange during the retreating process.

[0017] Compared with the prior art, the resin pouring pipe flow control mechanism of the utility model replaces the ball valve on the original pouring pipe to control the resin pouring mode, changes the pouring cross-section area through the clamping control of the external mechanism to control the pouring flow, saves the manual operation steps, is beneficial to realize the automatic control, the external clamping mechanism does not directly contact the liquid such as resin in the pipe, thereby guaranteeing that the utility model can be repeatedly used, saving the use of the ball valve, the clamping force of the clamping mechanism is large, the clamping force can reach 1400N, and has power-off self-locking force, the clamping force will not disappear when the pipe bursts in the critical situation, and the resin pouring pipe can be immediately closed, the flow area of the hose pipe is controlled through the movement stroke of the movable clamp, and compared with the traditional ball valve control, the control mode is simpler, and the control effect is better.
