Description

Technical Field

[0001] The utility model relates to the technical field of injection equipment, in particular to an injection equipment for fan blades. Background Art

[0002] The structural design of the fan blade is based on aerodynamic analysis, making full use of the performance of composite materials, so that the fan blade can obtain the largest wind sweeping area with the smallest mass, so that the fan blade has a higher ability to capture wind. As the rated power of the wind turbine increases, the length of the fan blade increases accordingly.

[0003] The fan blades formed by vacuum infusion resin glue can improve their own rigidity and have a significant effect on reducing the weight of the fan blades.

In addition, the infusion pipeline is not opened or closed in time, resulting in the inability to guarantee the glue supply amount and glue supply time, thus affecting the infusion quality.

Figure 3 It is a structural schematic diagram of the perfusion device in the embodiment of the utility model.

[0038] See also Figures 1 to 3 An embodiment of the utility model provides a casting device for wind turbine blades, which includes a mold body 100 and a plurality of casting devices 200 .

[0039] The mold body 100 is adaptively designed according to the length and shape of the fan blade. The mold body 100 is a carrier for making the fan blade to be molded. Under the action of external force, the injection molding material is formed into a fan blade with a specific shape and size. The mold body 100 is configured with a molding groove 110 along its length direction.

[0040] A plurality of groups of pouring devices 200 are arranged at intervals along the length direction of the mold body 100, and each group of pouring devices 200 is arranged across the mold body 100 and is located above the molding groove 110; the pouring device 200 includes a bracket 210, a control component 220 and a pouring pipeline 230 arranged on the bracket 210, and the pouring pipeline 230 is connected to the pouring main pipeline. A plurality of branch pipelines 240 are connected to the pouring pipeline 230, and the plurality of branch pipelines 240 are arranged at intervals along the width direction of the mold body 100, and are used to pour molding materials into the molding groove 110, and the molding materials can be epoxy resin or other system resin materials. An electronic control valve 250 is provided on each branch pipeline 240, and the electronic control valve 250 is electrically connected to the control component 220, and the control component 220 is used to control the action of the electronic control valve 250 to open or close the corresponding branch pipeline 240.

[0041] The embodiment of the utility model is described by taking a pouring device as an example, that is, the pouring device includes a mold body 100 and multiple groups of pouring devices 200 arranged at intervals on the mold body 100. In the actual processing process, multiple groups of pouring devices can be arranged side by side, and the control components 220 on each group of pouring devices are connected to the overall control system in communication, and the communication connection can be a wired connection or a wireless connection.

[0042] The number of the pouring devices 200 can be determined according to the length of the mold body 100 or the parameter requirements of each part of the fan blade. For example, a group of pouring devices 200 are arranged at intervals of 400mm to 500mm along the length direction of the mold body 100, and the structure of each group of pouring devices 200 is the same.

[0043] The electronic control valve 250 can be any type of switch element capable of controlling the opening or closing of the corresponding branch pipeline 240 and suitable for being controlled by a signal. For example, the electronic control valve 250 can be a solenoid valve, or can be improved by a corresponding mechanical structure.

[0044] The support 210 may be a gantry structure, including two oppositely arranged uprights 211 and a truss 212, the two uprights 211 being installed on both sides of the mold body 100, and the truss 212 being erected on the two uprights 211. The control assembly 220 is arranged on the truss 212, and the pouring pipeline 230 may be laid along the length direction of the truss 212.

[0045] It can be understood that the pouring equipment for fan blades provided by the embodiment of the utility model is provided by arranging multiple groups of pouring devices 200 at intervals along the length direction of the mold body 100, each group of pouring devices 200 is straddled on the mold body 100 and is located above the molding groove 110; the pouring device 200 includes a bracket 210 and a control component 220 and a pouring pipeline 230 arranged on the bracket 210, the pouring pipeline 230 is suitable for connecting to the main pouring pipeline, and a plurality of branch pipelines 240 are connected to the pouring pipeline 230, and the plurality of branch pipelines 240 are arranged at intervals along the width direction of the mold body 100, and are used to pour molding materials into the molding groove 110; each branch pipeline 240 is provided with an electronic control valve 250, and the electronic control valve 250 is electrically connected to the control component 220, and the control component 220 is used to control the action of the electronic control valve 250 to open or close the corresponding branch pipeline 240. When the filling device 200 needs to be controlled to open for filling operation, the control component 220 controls the electronic control valve 250 to make the corresponding branch pipeline 240 conductive, which is simple to operate, saves time and effort, and can replace manual opening or closing of the control valve on the filling pipeline 230. In addition, the opening or closing of the branch pipeline 240 can be accurately controlled, which is convenient for automatic control to perform filling operation.

[0046] In some embodiments of the present invention, each group of perfusion devices 200 also includes a flow monitoring component, which is electrically connected to the control component 220; the flow monitoring component is arranged in the branch pipeline 240, for monitoring the flow of the corresponding branch pipeline 240, and feeding back the monitored flow information to the control component 220.

[0047] Among them, the above-mentioned flow monitoring component can be a flow sensor, which is installed at the pipe mouth position of the branch pipeline 240 to monitor the flow of the molding material passing through this position, which serves as the basis for the control component 220 to calculate the injection volume of the corresponding branch pipeline 240.

[0048] For example, the control component 220 can control the closing of the electronic control valve 250 on the corresponding branch pipeline 240 according to the flow of the branch pipeline 240 monitored by the flow sensor, thereby cutting off the branch pipeline 240.

[0049] The above-mentioned flow monitoring component can also be other combined sensors, such as a sensor for monitoring flow rate and a timer for monitoring time, etc., which can determine the volume flowing through a unit area by flow rate and time, and thus determine the flow of the branch pipeline 240 according to the total flow time.

[0050] It should be noted that, when no flow monitoring component is provided on the branch pipeline 240 , the control component 220 can control the closing of the electronic control valve 250 on the corresponding branch pipeline 240 according to the perfusion time, thereby cutting off the branch pipeline 240 .

[0051] Figure 4 It is a schematic diagram of the structure of the electronic control valve 250 in the embodiment of the utility model.

[0052] See also Figure 4 In some embodiments of the present invention, the electronic control valve 250 includes a base 251 , a driving member 252 and a clamping member 253 .

[0053] The base 251 serves as a mounting carrier of the electronic control valve 250 , and its structure can be adjusted according to the mounting positions of the driving member 252 and the clamping member 253 . For example, the cross-sectional shape of the base 251 is “L”-shaped.

[0054] The driving member 252 is disposed on the base 251 and is used to provide clamping power for the clamping member 253. The driving member 252 can be a cylinder, an electric cylinder or an oil cylinder, etc. The driving member 252 can provide linear reciprocating power, and can also provide rotational or swinging power.

[0055] The clamping member 253 is arranged at the output end of the driving member 252, and is suitable for clamping the branch pipeline 240 under the action of the driving member 252 to close the branch pipeline 240; and is suitable for releasing the clamping of the branch pipeline 240 under the action of the driving member 252 to make the branch pipeline 240 conductive.

[0056] For example, the driving member 252 may be a swing arm cylinder, and the clamping member 253 may be a clamping claw disposed on the swing arm cylinder, or may be a clamping plate or other components independent of the swing arm cylinder and disposed on the corresponding clamping claw. When the swing arm cylinder drives the clamping claws to approach each other and have a tendency to abut, the branch pipeline 240 passing through the two clamping claws disposed opposite to each other is cut off, and the injection glue cannot flow through the branch pipeline 240.

[0057] Specifically, in the embodiment of the utility model, a guide portion 2511 is provided on the base 251 , and the guide portion 2511 separates the base 251 into a mounting portion 2512 and a clamping portion 2513 , and a guide hole is opened on the guide portion 2511 .

[0058] The driving member 252 includes an electric cylinder, which is arranged on the mounting portion 2512; the clamping member 253 is arranged on the piston rod of the electric cylinder, and the clamping member 253 can be a clamping block with a conical surface. The clamping member 253 passes through the guide hole on the guide portion 2511, and moves along the hole wall of the guide hole, abutting against the inner wall of the clamping member 2513 to close the branch pipeline 240; or, the clamping member 253 is suitable for moving away from the inner wall of the clamping member 2513 to make the branch pipeline 240 conductive.

[0059] In some embodiments of the present invention, the electronic control valve 250 further includes a reinforcement member 254 , and the reinforcement member 254 is disposed on the inner wall or the outer wall of the clamping portion 2513 .

[0060] Since the clamping portion 2513 needs to cooperate with the clamping member 253 to provide a clamping effect, a reinforcing member 254 is provided on at least one of the inner wall and the outer wall of the clamping portion 2513 to improve the structural strength of the base 251. The reinforcing member 254 can also be a baffle or a mounting member adapted to the structural installation setting.

[0061] In some embodiments of the utility model, each group of perfusion devices 200 also includes a position adjustment component (not shown in the figure), the position adjustment component is arranged on the bracket 210, the electronic control valve 250 is arranged on the position adjustment component, and the position adjustment component is used to adjust the position of the corresponding electronic control valve 250 and the branch pipeline 240 arranged on the electronic control valve 250.

[0062] Since the electronic control valve 250 can not only control the corresponding branch pipeline 240 to be turned on or off, but also the base 251 of the electronic control valve 250 can be fixed on the bracket 210 by bolts and other structures, the branch pipeline 240 can be positioned by passing through the electronic control valve 250.

[0063] When the position of the electronic control valve 250 can be adjusted, it is equivalent to that the position of the branch pipeline 240 passing through the electronic control valve 250 can be adjusted, so that the position of the branch pipeline 240 can be quickly matched and adjusted according to the position of the injection port, so that the branch pipeline 240 can be quickly connected to the injection port.

[0064] Among them, the position adjustment component can include two linear motors, namely linear motor A and linear motor B. Linear motor A is set on the bracket 210, and linear motor B is vertically connected to the load end of linear motor A. The base 251 of the electronic control valve 250 is connected to the linear motor B. Therefore, the electronic control valve 250 can adjust the position in the horizontal direction through linear motor A, and the electronic control valve 250 can adjust the position in the vertical direction through linear motor B.

[0065] In addition, the position adjustment component can also be composed of two sets of screw nut pairs, and the specific setting is the same as the setting method using the linear motor, and the above setting method can be referred to in detail. As long as the adjustment component can adjust the electronic control valve 250 in the horizontal direction and the vertical direction, it can be used.

[0066] Continue reading Figure 2 and Figure 3 In some embodiments of the utility model, the branch pipeline 240 includes a first pipeline 241 and a second pipeline 242, the first pipeline 241 is connected to the perfusion pipeline 230, one end of the second pipeline 242 is connected to the first pipeline 241 through a pipeline joint, and the other end of the second pipeline 242 is connected to the molding groove 110; the electronic control valve 250 is arranged in the first pipeline 241.

[0067] By configuring the branch pipeline 240 to be composed of two detachable parts, the electronic control valve 250 can be arranged on the pipeline which remains fixed therein, and the pipeline connected to the molding groove 110 can be adaptively changed and adjusted to match the injection ports at different positions. In other words, the injection device provided by the embodiment of the utility model can arrange the position of the injection port according to the on-site injection flow channel, and the position of the injection port can be flexibly adjusted.

[0068] Continue reading Figure 2 and Figure 3 In some embodiments of the present invention, the perfusion pipeline 230 includes a plurality of pipeline sections connected in sequence, and the number of pipeline sections corresponds to the number of branch pipelines 240. Two adjacent pipeline sections are connected through a tee, and the corresponding branch pipeline 240 is connected to the tee; the pipeline section at the head end is connected to the perfusion main pipeline, and the pipeline section at the tail end is connected to the corresponding branch pipeline 240 through an elbow joint.

[0069] This is equivalent to arranging the perfusion pipeline 230 in sections, so that each pipeline section is connected to a corresponding branch pipeline 240, which is convenient for later maintenance and replacement. Compared with arranging the perfusion pipeline 230 in one piece, the entire perfusion pipeline 230 will not be replaced due to damage to some sections, which can save maintenance costs.

[0070] Continue reading Figure 1 and Figure 2 In some embodiments of the present invention, a platform 300 is provided on at least one side of the mold body 100 , the platform 300 extends along the length direction of the mold body 100 , and the bracket 210 is fixed on the platform 300 .

[0071] The platform 300 is provided to facilitate maintenance and installation by the staff. Meanwhile, the bracket 210 is fixed on the platform 300 to facilitate installation.

[0072] Figure 5 It is a state schematic diagram of a perfusion device for fan blades provided in an embodiment of the utility model.

[0073] See also Figure 5 In some embodiments of the present invention, the control assembly 220 of each perfusion device 200 is provided with a wireless receiving module and a wireless transmitting module, and the wireless receiving module and the wireless transmitting module are electrically connected to an external overall control system.

[0074] By wirelessly connecting the overall control system and each group of perfusion devices 200 using a wireless communication module, each group of perfusion devices 200 can be remotely controlled to perform perfusion operations simultaneously, or a certain group of perfusion devices 200 can be individually controlled to perform perfusion operations.

[0075] Figure 6It is a schematic flow chart of the perfusion method provided in the embodiment of the utility model.

[0076] See also Figure 6 The utility model also provides a method for pouring wind turbine blades. The method is controlled based on the above-mentioned pouring equipment and includes the following steps S100 and S200.

[0077] Step S100: Open the corresponding electronic control valve 250 based on preset conditions to make the branch pipeline 240 corresponding to the electronic control valve 250 conductive; wherein the preset conditions include the vacuum degree of the molding groove 110 meeting the preset vacuum conditions, or the preset conditions include the system's set program.

[0078] Step S200: determining that the filling time of the branch pipeline 240 reaches the preset filling time, and controlling the electronic control valve 250 to operate so that the corresponding branch pipeline 240 is closed.

[0079] It can be understood that the infusion equipment provided in the embodiment of the utility model directly lays the fiber-reinforced material on the molding groove 110 of the mold body 100, and lays a peeling layer on the fiber-reinforced material. The peeling layer is usually a very thin layer of low-porosity, low-permeability fiber fabric, and a high-permeability medium is laid on the peeling layer, which is then covered and sealed with a vacuum film.

[0080] That is, the mold body 100 is sealed with a film, and the vacuum pump is evacuated to a negative pressure state. A vacuum detection component can be set on the infusion equipment, and the vacuum detection component is used to detect the vacuum pressure in the product. When the vacuum detection component detects that the vacuum degree of the product meets the requirement, the detection information is fed back to the control component 220. The control component 220 controls the electronic control valve 250 of each group of infusion devices 200 to open, so that the corresponding branch pipeline 240 is connected, and the resin enters the entire vacuum infusion system through the branch pipeline 240. The main direction of the resin flow is guided by the guide pipe, and the guide cloth distributes the resin to every corner of the layer. After curing, the demoulding cloth is peeled off, thereby obtaining a layer structure with high density and low glue content.

[0081] Alternatively, the control component 220 opens the corresponding electronic control valve 250 based on a set program to make the branch pipeline 240 corresponding to the electronic control valve 250 conductive.

[0082] Before the start of infusion, the initial states of all electronic control valves 250 are closed; the vacuum bag film is evacuated by a vacuum pump so that the vacuum bag film and the mold body 100 are in a vacuum state, that is, when the vacuum degree is 0.098-0.101MPa, the vacuum pump is turned on to evacuate the main infusion pipeline so that the interior of the main infusion pipeline is in a vacuum state, and the negative pressure in the main infusion pipeline is used to continuously suck the resin glue in the glue barrel into the main infusion pipeline.

[0083] The injection equipment is adjusted to the corresponding position on the mold body 100 by means of a crane, the injection port is set according to the injection channel layout, the branch pipelines 240 are placed in turn at the positions of the corresponding injection ports of each cross section, and each branch pipeline 240 is placed between the clamping piece 253 and the clamping portion 2513 of the electronic control valve 250. According to the spacing requirements of the branch pipelines 240, the position adjustment component is controlled to adjust the position of the corresponding electronic control valve 250 to ensure the followability of the branch pipeline 240 located between the clamping piece 253 and the clamping portion 2513.

[0084] By clicking on the remote control, the program runs automatically (i.e., according to the set program, the perfusion equipment opens the corresponding electronic control valves 250 one by one in sequence, thereby opening the corresponding branch pipelines 240). When the electronic control valves 250 are opened continuously for a preset time, the electronic control valves 250 are controlled by the remote control to close synchronously or sequentially, so that the corresponding branch pipelines 240 are closed.

[0085] The set program is that the glue in the main perfusion pipeline will flow to the perfusion pipeline 230 of each group of perfusion devices 200 on the cross-section of the mold body 100, and the glue in each row of perfusion pipelines 230 will flow to each branch pipeline 240.
