The utility model provides a wind-powered electricity generation blade shaping fills uses vacuum monitoring system's embodiment:
in order to better understand the vacuum monitoring system for wind turbine blade molding and pouring in the present embodiment, the problem of existing pressure monitoring during wind turbine blade molding and pouring is further explained, as shown in fig. 1, in the existing wind turbine blade molding and pouring, a corresponding product laying layer 6 is arranged on a mold 8 for preparing a wind turbine blade, then a corresponding flow guide net 7 and an adhesive injection pipe (not shown in the figure) are arranged on the surface of the product laying layer, the whole system is sealed by using a sealing tape and a vacuum bag film 16, the vacuum bag film 16 is evacuated by using a vacuum pump 13 and an exhaust pipeline connecting the vacuum pump 13 and the vacuum bag film 16, so that the vacuum bag film 16 maintains a vacuum state, thereby establishing a wind turbine blade molding and pouring vacuum area, and injecting resin into the adhesive injection pipe to perform the wind turbine blade molding.
At present, the vacuum degree of a vacuum area of a vacuum bag film 16 is often monitored by arranging a mechanical or digital display vacuum meter 14 on an air suction pipeline 15 of a vacuum pump 13, and meanwhile, the air leakage condition of the vacuum area is monitored, so that in the process of filling and curing, when the vacuum area formed by vacuum filling is slightly leaked or is in the initial stage of air leakage, the vacuum pump 13 continuously operates because the vacuum of the vacuum area is kept, the pressure fluctuation of the mechanical or digital display vacuum meter 14 arranged on the air suction pipeline 15 of the vacuum pump to the vacuum area cannot be reflected in time, the occurrence of air leakage can be only detected after the air leakage is obvious, therefore, the judgment of the air leakage is delayed, and a worker cannot timely take effective measures to avoid the quality problem of the wind power blades caused by the air leakage.
Combine shown in fig. 1, it is different with current setting, the wind-powered electricity generation blade shaping of this embodiment fills and uses vacuum monitoring system includes gas collecting pipe 2 and pressure sensor 5, wherein, gas collecting pipe 2 is used for communicateing wind-powered electricity generation blade shaping and fills the vacuum area, pressure sensor 5 passes through air duct 3 and connects gas collecting pipe 2, a pressure state for detecting the vacuum area, pressure sensor 5 is last to be connected with PLC controller 11 through wire 9, PLC controller 11 is used for gathering the vacuum area pressure information that pressure sensor 5 obtained, it is equipped with display screen 12 to connect PLC controller 11, after PLC controller 11 gathered pressure information, accessible PLC controller 11 presents pressure information on display screen 12 with the digital display mode, so that the pressure oscillation state of staff's visual monitoring vacuum area.
Through setting up the vacuous pressure sensor of direct monitoring, can in time make the reflection to the pressure fluctuation of vacuum area, can discover the emergence of gas leakage at the comparatively initial stage of gas leakage or when not obvious, help the staff in time to take effective measure to avoid the wind-powered electricity generation blade quality problem because of gas leakage production to improve wind-powered electricity generation blade production quality.
In this embodiment, steel wire hose can be chooseed for use to air duct 3, sets up two-way valve 4 on steel wire hose, has made things convenient for steel wire hose and 4 two-way valve's high-speed joint and demolishs, simultaneously, is favorable to controlling pressure sensor's operation to and the convenient vacuum gas tightness when ensureing that the sensor is connected and demolishs.
In combination with the above, because the glue injection pipe is a relatively critical area, the risk of air leakage is relatively high, as shown in fig. 1, when the gas collecting pipe 2 is arranged, the gas collecting pipe 2 can be communicated with the glue injection pipe, so that the pressure sensor 5 can quickly detect the pressure fluctuation in the area, and the monitoring effectiveness is improved.
Referring to fig. 1, after the PLC controller 11 collects the pressure information of the pressure sensor 5, in order to facilitate the monitoring of the pressure fluctuation of the vacuum area by the staff, the PLC controller 11 is further connected to an alarm 10, when the pressure fluctuation exceeds a preset safety value, the alarm 10 is used for giving an alarm, and the alarm 10 may be a commercially available general sound or sound-light alarm.
In the above embodiment, the gas collecting tube 3 is directly communicated with the wind power blade molding perfusion vacuum area, and when resin is perfused, there is a risk that the resin enters the pressure sensor 5 along the gas collecting tube, for this reason, in another embodiment, as shown in fig. 1, the VAP film 1 may also be disposed at one end of the gas collecting tube 2 located in the wind power blade molding perfusion vacuum area, and since the VAP film 1 only allows gas to permeate through, gas conduction is achieved without conducting glue, and therefore, after the VAP film 1 is disposed, the resin can be effectively prevented from entering the pressure sensor 5 during perfusion, and pressure monitoring of the pressure sensor 5 on the vacuum area is not affected.
When the VAP film 1 is specifically arranged, the VAP film 1 can be cut into a square or round shape with a proper size, then the periphery of the VAP film 1 is hermetically connected with the gas collecting pipe 2, and the periphery of the VAP film can be fixed on the gas collecting pipe 2 through a sealing adhesive tape, so that the resin is prevented from entering the gas collecting pipe 2 from the junction of the VAP film 1 and the gas collecting pipe 2.
In actual installation, because the VAP film 1 is soft, a net-shaped support structure such as a flow guiding net can be arranged between the VAP film 1 and the gas collecting pipe 2 to enhance the resistance of the VAP film 1 against resin impact.
In other embodiments, when the gas collecting tube 2 and the VAP film 1 are specifically arranged, a plurality of gas collecting tubes 2 and VAP films 1 can be arranged, and a plurality of gas guide tubes 3 and two-way valves 4 are arranged on the gas collecting tube 2, so that the VAP film 1, the gas collecting tube 2, the gas guide tubes 3 and the two-way valves 4 are arranged in the wind power blade forming perfusion vacuum area, especially in some key areas, according to specific conditions, in use, the effect of monitoring whether gas leakage occurs in the vacuum areas at different positions is achieved by detaching and connecting the two-way valves 4 and the pressure sensors 5 at any time, so that the monitoring is more effective, of course, the situation of vacuum fluctuation at a plurality of positions of the wind power blade forming perfusion vacuum area can be simultaneously acquired by the PLC controller 11 by respectively arranging one pressure sensor 5 for each VAP film 1, gas collecting tube 2, gas guide tubes 3 and two-way valves 4, such monitoring may be more effective, but the monitoring cost may be increased.
It should be noted that, although the prior art has not been described in detail herein, the above embodiments are merely provided to illustrate the present invention, but the present invention is not limited to the above embodiments, and any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention all fall within the scope of the present invention.
