为了弥补现有技术的不足，解决管道中的水泵在工作时产生振动带动传感器在管道上晃动，造成传感器在检测过程中由于晃动影响产生检测数据存在较大误差，进而降低了传感器使用的可靠程度的问题，本发明提出了一种电感式水压传感器。
本发明解决其技术问题所采用的技术方案是：本发明所述的一种电感式水压传感器，包括基座、基体、线圈和磁芯；所述基座中心位置开设有一号孔，且基座底部以一号孔为圆心开设有环形的一号槽，一号槽内均匀开设有一组弧形的T型槽；所述T型槽内均套设有滑块，且滑块与T型槽滑动连接，滑块与T型槽远离一号孔的内壁通过复位弹簧连接，滑块远离基座的一端位于T型槽外，滑块远离T型槽的一端固连有弧形板，且弧形板圆弧外表面设置有螺纹，弧形板远离基座的一端套设有圆环，弧形板与圆环转动连接，每个弧形板远离基座的一端通过圆环串连；所述一号孔远离弧形板的一端固连有膜片；所述基座上均匀开设有一组二号孔，且二号孔远离一号孔，二号孔内靠近弧形板的位置转动连接有转轴，且转轴上均匀固连有一组凸块；所述基座顶部安装有基体，且基体与基座通过螺栓连接；所述基体对应二号孔的位置均固连有一号块，且一号块与二号孔滑动连接；所述基体顶部中心位置设置有螺钉，且螺钉靠近基体的一端位于基体内，基体内以螺钉为圆心固连有一号管，一号管内滑动连接有垫片，垫片顶部与螺钉底部贴合，一号管外表面套设有二号管，一号管与二号管滑动连接；所述二号管远离一号管的一端固连有一号板，且一号板与垫片通过复位弹簧连接，一号板顶部远离二号管的位置固连有磁芯；所述基体内对应磁芯的位置固连有线圈，且线圈通过数据线引出基体内。
使用时，在本发明生产时，将线圈通过数据线引出基体内并与市场上的常规电感式压力传感器领域的单片机电性连接；电感式水压传感器安装在管道或者缸体所需检测位置时，首先将弧形板远离基座的一端对应安装孔通过扳手扭入，弧形板外表面螺纹与安装孔接触进入安装孔，弧形板远离基座的一端进入安装孔后，随着使用人员不断将基座旋转，弧形板受安装孔导向作用和圆环的限位作用，使得每个弧形板以圆环为中心向靠近一号孔方向运动，每个弧形板靠近基座的一端逐渐相互靠近，直至弧形板进入安装孔，此时弧形板靠近基座的一端相互紧贴形成密闭空间，通过设置滑块，弧形板靠近基座的一端在一号槽内运动带动滑块运动，滑块在T型槽内滑动，直至弧形板进入安装孔，复位弹簧受滑块向靠近一号孔方向运动而拉伸产生拉力，从而使得弧形板受滑块影响紧贴安装孔内壁，增加弧形板与安装孔之间的紧密程度，从而增加基座安装后的稳定性，进而增加压力检测准确程度，避免在将传感器通过螺栓扭入安装孔后，由于水泵振动带动管道振动，从而带动基座与管道之间形成振动，在长时间使用过程中，导致基座发生松动，造成检测准确程度受到影响；通过设置凸块，基体通过弧形板不断进入安装孔内，管道表面与凸块摩擦使得凸块运动，凸块运动带动转轴运动，直至转轴接触管道，此时凸块位于管道两侧，将基体通过螺栓安装在基座顶部，一号块滑动进入二号孔内，直至一号块接触凸块，使得一号块 对凸块产生限位作用，使得凸块锁定，从而使得管道锁定在相邻凸块之间，增加基座安装后的稳定性，进而增加压力检测准确程度，避免基座受振动影响逐渐松动，造成检测准确程度受到影响；通过弧形板和凸块之间的配合，在使用人员通过扳手即可对基座进行安装，且增加传感器的稳定程度，在基体长时间使用后需要更换时，仅需松开基座与基体之间的螺栓即可，避免将基座扭出安装孔，频繁扭动后对安装孔造成磨损，导致稳定程度降低；在进行检测时，液体进入弧形板组成的密闭空间和一号孔内对膜片顶推，膜片受力产生形变带动一号板运动，一号板带动磁芯运动，磁芯远离线圈运动，磁芯与线圈之间重合的部分的减少，改变线圈的磁导率，从而改变线圈的电感量，通过数据线将电感量输出至单片机内成为电信号，单片机通过计算得出当前管道中的压力值；通过螺钉调节二号管中复位弹簧的压力。
优选的，所述凸块截面为半圆状。
使用时，基座通过弧形板不断进入安装孔内，管道表面接触凸块，由于凸块截面为半圆状，基座继续向管道表面靠近，管道接触凸块后，凸块受弧形表面导向作用，使得管道弧形表面拨动凸块，增加凸块运动的流畅性，防止凸块接触管道后，凸块远离转轴的部分抵住管道表面，从而阻止凸块运动，导致基座运动受阻；凸块运动带动转轴运动，直至转轴接触管道，此时凸块位于管道两侧，将基体通过螺栓安装在基座顶部，一号块滑动进入二号孔内，直至一号块接触凸块，使得一号块对凸块产生限位作用，使得凸块锁定，从而将基座锁定在管道表面。
优选的，所述弧形板远离二号孔的一端为倾斜设置，且弧形板的外表面垂直状态时，弧形板的内表面倾斜朝向一号孔。
使用时，随着使用人员不断将基座旋转，弧形板受安装孔导向作用和圆环的限位作用，使得每个弧形板以圆环为中心向靠近一号孔方向运动，每个弧形板靠近基座的一端逐渐相互靠近，直至弧形板进入安装孔，此时弧形板靠近基座的一端相互紧贴形成密闭空间，由于弧形板远离二号孔的一端为倾斜设置，且弧形板的外表面垂直状态时，弧形板的内表面倾斜朝向一号孔，使得弧形板内表面组成的密闭空间靠近一号孔的部分孔径小，弧形板内表面组成的密闭空间远离一号孔的部分孔径大，液体通过弧形板内表面组成的密闭空间时流速增加，从而使得膜片受到液体压力增加，进而增加传感器的灵敏程度，避免膜片受液体流动影响小，导致膜片运动效果降低，从而降低传感器灵敏程度。
优选的，所述膜片截面为波纹状设置。
使用时，液体进入弧形板组成的密闭空间和一号孔内对膜片顶推，膜片受力产生形变 带动一号板运动，通过设置膜片截面为波纹状，膜片受力形变拱起，膜片中的褶皱部分伸展，增加膜片的伸展程度，从而增加膜片的运动效果，进而增加传感器的灵敏程度，避免膜片受自身弹性形变后产生的拉力影响，消耗一部分液体推动膜片的作用力，降低传感器的检测的准确性；一号板带动磁芯运动，磁芯远离线圈运动，磁芯与线圈之间重合的部分的减少，改变线圈的磁导率，从而改变线圈的电感量，通过数据线将电感量输出至单片机内成为电信号，单片机通过计算得出当前管道中的压力值。
优选的，所述弧形板位于相邻弧形板两侧均设置有防水胶条。
使用时，通过设置有防水胶条，弧形板外表面螺纹与安装孔接触进入安装孔，弧形板远离基座的一端进入安装孔后，随着使用人员不断将基座旋转，弧形板受安装孔导向作用和圆环的限位作用，使得每个弧形板以圆环为中心向靠近一号孔方向运动，每个弧形板靠近基座的一端逐渐相互靠近，弧形板带动防水胶条运动，相邻弧形板接触时，位于相邻弧形板之间的防水胶条受挤压产生形变，从而对相邻弧形板之间的空隙进行封闭，增加相邻弧形板之间的密封性，从而增加传感器检测的准确程度，避免相邻弧形板之间存在空隙，导致液体渗漏，造成检测精度降低。
优选的，所述一号块靠近二号孔的一端为圆弧状；所述一号板底部远离膜片位置均匀固连有一组减震弹簧。
使用时，通过设置一号块靠近二号孔的一端为圆弧状，一号块滑动进入二号孔时，一号块的圆弧部分接触位于远离管道的凸块表面，远离管道的凸块受一号块圆弧部分的限位作用，减少远离管道的凸块在一号块表面的晃动间隙，增加基座安装后的稳定性，进而增加压力检测准确程度，从而增加传感器的使用可靠性；通过设置减震弹簧，当管道内的压力受外界因素影响急剧增加时，膜片受力形变拱起带动一号板运动，一号板带动二号管运动，二号管内的复位弹簧受压急剧增加，在二号管内的复位弹簧伸展带动一号板进行复位时，减震弹簧接触基座表面，对一号板进行减震，增加传感器的使用可靠性，从而增加传感器的使用寿命，防止二号管内的复位弹簧带动一号板复位时，一号板与基座产生碰撞，导致一号板或者磁芯受损，甚至造成传感器损坏。
本发明的有益效果如下：
1.本发明所述的一种电感式水压传感器，通过设置凸块，基体通过弧形板不断进入安装孔内，管道表面与凸块摩擦使得凸块运动，凸块运动带动转轴运动，直至转轴接触管道，此时凸块位于管道两侧，将基体通过螺栓安装在基座顶部，一号块滑动进入二号孔内，直至一号块接触凸块，使得一号块对凸块产生限位作用，从而使得管道锁定在相邻凸块之间， 增加基座安装后的稳定性，进而增加压力检测准确程度。
2.本发明所述的一种电感式水压传感器，通过设置弧形板远离二号孔的一端为倾斜，且弧形板的外表面垂直状态时，弧形板的内表面倾斜朝向一号孔，使得弧形板内表面组成的密闭空间靠近一号孔的部分孔径小，弧形板内表面组成的密闭空间远离一号孔的部分孔径大，液体通过弧形板内表面组成的密闭空间时流速增加，从而使得膜片受到液体压力增加，进而增加传感器的灵敏程度。

使用时，在本发明生产时，将线圈41通过数据线引出基体4内并与市场上的常规电感式压力传感器领域的单片机电性连接；电感式水压传感器安装在管道或者缸体所需检测位置时，首先将弧形板2远离基座1的一端对应安装孔通过扳手扭入，弧形板2外表面螺纹21与安装孔接触，弧形板2远离基座1的一端进入安装孔后，随着使用人员不断将基座1旋转，弧形板2受安装孔导向作用和圆环22的限位作用，使得每个弧形板2以圆环22为中心向靠近一号孔11方向运动，每个弧形板2靠近基座1的一端逐渐相互靠近，直至弧形板2进入安装孔，此时弧形板2靠近基座1的一端相互紧贴形成密闭空间，通过设置滑块15，弧形板2靠近基座1的一端在一号槽13内运动带动滑块15运动，滑块15在T型槽14内滑动，直至弧形板2进入安装孔，复位弹簧受滑块15向靠近一号孔11方向运动而拉伸产生拉力，从而使得弧形板2受滑块15影响紧贴安装孔内壁，增加弧形板2与安装孔之间的紧密程度，从而增加基座1安装后的稳定性，进而增加压力检测准确程度，避免在将传感器通过螺栓扭入安装孔后，由于水泵振动带动管道振动，从而带动基座1与管道之间形成振动，在长时间使用过程中，导致基座1发生松动，造成检测准确程度受到影响；通过设置凸块32，基体4通过弧形板2不断进入安装孔内，管道表面接触凸块32，此时基座1继续向管道表面靠近，管道表面与凸块32摩擦使得凸块32运动，凸块32运动带动转轴31运动，直至转轴31接触管道，此时凸块32位于管道两侧，将基体4通过螺栓安装在基座1顶部，一号块42滑动进入二号孔3内，直至一号块42接触凸块32，使得一号块42对凸块32产生限位作用，从而使得管道锁定在相邻凸块32之间，增加基座1安装后的稳定性，进而增加压力检测准确程度，避免基座1受振动影响逐渐松动，造成检测准确程度受到影响；通过弧形板2和凸块32之间的配合，在使用人员通过扳手即可对基座1进行安装，且增加传感器的稳定程度，在基体4长时间使用后需要更换时，仅需松开基座1与基体4之间的螺栓即可，避免将基座1扭出安装孔，频繁扭动后对安装孔造成磨损，导致稳定程度降低；在进行检测时，液体进入弧形板2组成的密闭空间和一号孔11 内对膜片12顶推，膜片12受力产生形变带动一号板5运动，一号板5带动磁芯51运动，磁芯51远离线圈41运动，磁芯51与线圈41之间重合的部分的减少，改变线圈41的磁导率，从而改变线圈41的电感量，通过数据线将电感量输出至单片机内成为电信号，单片机通过计算得出当前管道中的压力值；通过螺钉43调节二号管46中复位弹簧的压力。
作为本发明的一种实施方式，所述凸块32截面为半圆状。
使用时，基座1通过弧形板2不断进入安装孔内，管道表面接触凸块32，由于凸块32截面为半圆状，基座1继续向管道表面靠近，管道接触凸块32后，凸块32受弧形表面导向作用，使得管道弧形表面拨动凸块32，增加凸块32运动的流畅性，防止凸块32接触管道后，凸块32远离转轴31的部分抵住管道表面，从而阻止凸块32运动，导致基座1运动受阻；凸块32运动带动转轴31运动，直至转轴31接触管道，此时凸块32位于管道两侧，将基体4通过螺栓安装在基座1顶部，一号块42滑动进入二号孔3内，直至一号块42接触凸块32，使得一号块42对凸块32产生限位作用，使得凸块32锁定，从而将基座1锁定在管道表面。
作为本发明的一种实施方式，所述弧形板2远离二号孔3的一端为倾斜设置，且弧形板2的外表面垂直状态时，弧形板2的内表面倾斜朝向一号孔11。
使用时，随着使用人员不断将基座1旋转，弧形板2受安装孔导向作用和圆环22的限位作用，使得每个弧形板2以圆环22为中心向靠近一号孔11方向运动，每个弧形板2靠近基座1的一端逐渐相互靠近，直至弧形板2进入安装孔，此时弧形板2靠近基座1的一端相互紧贴形成密闭空间，由于弧形板2远离二号孔3的一端为倾斜设置，且弧形板2的外表面垂直状态时，弧形板2的内表面倾斜朝向一号孔11，使得弧形板2内表面组成的密闭空间靠近一号孔11的部分孔径小，弧形板2内表面组成的密闭空间远离一号孔11的部分孔径大，液体通过弧形板2内表面组成的密闭空间时流速增加，从而使得膜片12受到液体压力增加，进而增加传感器的灵敏程度，避免膜片12受液体流动影响小，导致膜片12运动效果降低，从而降低传感器灵敏程度。
作为本发明的一种实施方式，所述膜片12截面为波纹状设置。
使用时，液体进入弧形板2组成的密闭空间和一号孔11内对膜片12顶推，膜片12受力产生形变带动一号板5运动，通过设置膜片12截面为波纹状，膜片12受力形变拱起，膜片12中的褶皱部分伸展，增加膜片12的伸展程度，从而增加膜片12的运动效果，进而增加传感器的灵敏程度，避免膜片12受自身弹性形变后产生的拉力影响，消耗一部分液体推动膜片12的作用力，降低传感器的检测的准确性；一号板5带动磁芯51运动，磁 芯51远离线圈41运动，磁芯51与线圈41之间重合的部分的减少，改变线圈41的磁导率，从而改变线圈41的电感量，通过数据线将电感量输出至单片机内成为电信号，单片机通过计算得出当前管道中的压力值。
作为本发明的一种实施方式，所述弧形板2位于相邻弧形板2两侧均设置有防水胶条52。
使用时，通过设置有防水胶条52，弧形板2外表面螺纹21与安装孔接触进入安装孔，弧形板2远离基座1的一端进入安装孔后，随着使用人员不断将基座1旋转，弧形板2受安装孔导向作用和圆环22的限位作用，使得每个弧形板2以圆环22为中心向靠近一号孔11方向运动，每个弧形板2靠近基座1的一端逐渐相互靠近，弧形板2带动防水胶条52运动，相邻弧形板2接触时，位于相邻弧形板2之间的防水胶条52受挤压产生形变，从而对相邻弧形板2之间的空隙进行封闭，增加相邻弧形板2之间的密封性，从而增加传感器检测的准确程度，避免相邻弧形板2之间存在空隙，导致液体渗漏，造成检测精度降低。
作为本发明的一种实施方式，所述一号块42靠近二号孔3的一端为圆弧状；所述一号板5底部远离膜片12位置均匀固连有一组减震弹簧53。
使用时，通过设置一号块42靠近二号孔3的一端为圆弧状，一号块42滑动进入二号孔3时，一号块42的圆弧部分接触位于远离管道的凸块32表面，远离管道的凸块32受一号块42圆弧部分的限位作用，减少远离管道的凸块32在一号块42表面的晃动间隙，增加基座1安装后的稳定性，进而增加压力检测准确程度，从而增加传感器的使用可靠性；通过设置减震弹簧53，当管道内的压力受外界因素影响急剧增加时，膜片12受力形变拱起带动一号板5运动，一号板5带动二号管46运动，二号管46内的复位弹簧受压急剧增加，在二号管46内的复位弹簧伸展带动一号板5进行复位时，减震弹簧53接触基座1表面，对一号板5进行减震，增加传感器的使用可靠性，从而增加传感器的使用寿命，防止二号管46内的复位弹簧带动一号板5复位时，一号板5与基座1产生碰撞，导致一号板5或者磁芯51受损，甚至造成传感器损坏。
具体工作流程如下：
将弧形板2远离基座1的一端对应安装孔通过扳手扭入，弧形板2远离基座1的一端进入安装孔后，弧形板2受安装孔导向作用和圆环22的限位作用，使得每个弧形板2以圆环22为中心向靠近一号孔11方向运动，每个弧形板2靠近基座1的一端逐渐相互靠近，弧形板2带动滑块15运动，滑块15在T型槽14内滑动，直至弧形板2进入安装孔，此时弧形板2靠近基座1的一端相互紧贴形成密闭空间；基体4通过弧形板2不断进入安装 孔内，管道表面接触凸块32，管道表面与凸块32摩擦使得凸块32运动，凸块32运动带动转轴31运动，直至转轴31接触管道；将基体4通过螺栓安装在基座1顶部，一号块42滑动进入二号孔3内，直至一号块42接触凸块32；在进行检测时，液体进入弧形板2组成的密闭空间和一号孔11内对膜片12顶推，膜片12受力产生形变带动一号板5运动，一号板5带动磁芯51运动，磁芯51远离线圈41运动，磁芯51与线圈41之间重合的部分的减少，改变线圈41的磁导率，从而改变线圈41的电感量，通过数据线将电感量输出至单片机内成为电信号，单片机通过计算得出当前管道中的压力值；弧形板2的外表面垂直状态时，弧形板2的内表面倾斜朝向一号孔11，使得弧形板2内表面组成的密闭空间靠近一号孔11的部分孔径小，弧形板2内表面组成的密闭空间远离一号孔11的部分孔径大；膜片12受力形变拱起，膜片12中的褶皱部分伸展；弧形板2带动防水胶条52运动，相邻弧形板2接触时，位于相邻弧形板2之间的防水胶条52受挤压产生形变，从而对相邻弧形板2之间的空隙进行封闭；一号块42的圆弧部分接触位于远离管道的凸块32表面，远离管道的凸块32受一号块42圆弧部分的限位作用；当管道内的压力受外界因素影响急剧增加时，膜片12受力形变拱起带动一号板5运动，一号板5带动二号管46运动，二号管46内的复位弹簧受压急剧增加，在二号管46内的复位弹簧伸展带动一号板5进行复位时，减震弹簧53接触基座1表面，对一号板5进行减震。
