本发明涉及泵体技术领域，具体涉及一种集成式泵站。
背景技术
乳化液泵用于采煤工作面，为液压支架提供高压乳化液。乳化液泵一般以乳化液(95％水加5％乳化油)作为介质，通过电机旋转带动泵站曲轴，靠曲轴的旋转带动柱塞做往复运动，实现吸液和排液，最终输出高压乳化液。液压支架靠乳化液泵提供的高压乳化液推动的液压缸支撑伸缩。现阶段一般采取泵头与电机通过联轴器连接的方案，对于需要变频调速的电机，搭配一台防爆变频器，电机与变频器之间通过动力电缆连接。
相关技术中，一般采用泵站、电机、变频器等设备分体式设计方式，一般变频器需要单独占用一个设备列车，加长了顺槽区域集成供液系统的整体长度，给综采工作面的推进带来不便，泵站、电机、变频器、控制器分别进行安装调试，且需要分别设置水冷系统和电力系统，增加安装成本、设备整体重量和占地面积、维护成本。

具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
下面参考附图描述本发明实施例的集成式泵站100。如图1至图4所示，根据本发明实施例的集成式泵站100包括安装架1、泵体2和电驱装置。
泵体2设在安装架1上。电驱装置包括箱体3、电机、变频器和控制器，箱体3设在安装架1上，电机、变频器和控制器设在箱体3内，电机与泵体2相连，电机通过电线与变频器连接，变频器通过电线与控制器连接，电机的水冷管路、变频器的水冷管路和泵体2的油冷却器24依次连通。
根据本发明实施例的集成式泵站100通过将泵体2和箱体3设在安装架1上，且电机、变频器和控制器设在箱体3内，从而使得电机、变频器和控制器通过箱体3集成在安装架1上，即安装架1上设有泵体2、电机、变频器和控制器。由此，只需使用一个设备列车即可承载根据本发明实施例的集成式泵站100，集成式泵站100内的变频器无需再占用一个设备列车，从而便于设备列车带动集成式泵站100在巷道内移动。
且电机的水冷管路、变频器的水冷管路和泵体2的油冷却器24依次连通，由此，只需将一个外接的进水管与电机的水冷管路连通，一个外接的出水管与和泵体2的油冷却器24连通，即可完成集成式泵站100的水冷系统的冷却水的流通。无需为每个部分(泵体2、电机和变频器)单独设置外接的进水管和外接的出水管，从而减少外接的进水管的数量和外接的出水管的数量，进一步增加了集成式泵站100的集成度，且提高了集成式泵站100的便利性。也使得集成式泵站100在使用时占用空间小、适用于空间狭小的地方。电机的水冷管路、变频器的水冷管路和泵体2的油冷却器24依次连通也可使得冷却水依次对电机、变频器和泵体2的油冷却器进行冷却，电机发热量比变频器的发热量和泵体2的发热量大，且电机冷却的优先级高，对电机冷却后再对变频器和泵体2的油冷却器进行冷却可便于集成式泵站100的顺利运行，满足集成式泵站100的冷却要求。
因此，根据本发明实施例的集成式泵站100具有集成度高、便利性高、占用空间小和便于在巷道内移动的优点。
如图1至图4所示，根据本发明实施例的集成式泵站100包括安装架1、泵体2和电驱装置。
泵体2设在安装架1上，具体地，安装架1上设有与泵体2配合的吸液管22和卸液管23，吸液管22的延伸方向和卸液管23的延伸方向与安装架1的长度方向一致。例如，安装架1的长度方向为前后方向，吸液管22的延伸方向和卸液管23的延伸方向为前后方向。前后方向如图中的箭头A所示。
电驱装置包括箱体3、电机、变频器和控制器，箱体3设在安装架1上。
如图1至图4所示，在一些实施例中，箱体3包括顶板31、底板32、第一侧板33、第二侧板34、第三侧板35和第四侧板36。顶板31和底板32在上下方向上相对设置，第一侧板33和第二侧板34在第一方向上相对设置，第三侧板35和第四侧板36在第二方向上相对设置。上下方向、第一方向和第二方向中的任两者相互垂直。第一方向可以是左右方向，第二方向可以是前后方向，左右方向如图中的箭头B所示，上下方向如图中的箭头C所示。例如，顶板31位于底板32上方，底板32设在安装架1上；第一侧板33位于第二侧板34的左侧，第三侧板35位于第四侧板36的前侧。
电机、变频器和控制器设在箱体3内，电机与泵体2相连，从而使得电机为泵体2提供动力。电机通过电线与变频器连接，变频器通过电线与控制器连接，以便变频器和控制器与电机配合，从而控制电机的启停和转动速度。
具体地，箱体3位于泵体2的后侧，箱体3的第三侧板35上设有防护罩37，电机 的输出轴穿过第三侧板35并伸入防护罩37内与泵体2相连。泵体2包括曲轴、曲轴箱21和联轴器，联轴器的一部分位于防护罩7内，联轴器的一端与曲轴相连，联轴器的另一端与电机的输出轴相连。变频器可控制电机的输出轴的转动速度，由此无需配备减速机，从而可提高电机的输出轴的传动效率。不配备减速机即可降低传动部分的重量，也可降低传动部分发生损坏的概率。
电机的水冷管路、变频器的水冷管路和泵体2的油冷却器24依次连通。
如图1和图4所示，在一些实施例中，箱体3具有冷却水进口301和冷却水出口302。电机的水冷管路与电机的主体贴合，以便为电机主体降温，电机的水冷管路具有第一进水口和第一出水口。变频器包括变频电机，变频器的水冷管路与变频电机贴合，从而使得变频器的水冷管路便于为变频电机降温，变频器的水冷管路具有第二进水口和第二出水口。泵体2包括油箱和油冷却器24，油冷却器24和油箱贴合，从而便于油冷却器24为油箱(油箱内的油体)降温，油冷却器24包括第三进水口和第三出水口241。
第一进水口与冷却水进口301连通，第二进水口与第一出水口连通，第三进水口与第二出水口连通，第三出水口241与冷却水出口302连通，从而使得电机的水冷管路、变频器的水冷管路和泵体2的油冷却器24依次连通。电机的水冷管路、变频器的水冷管路和泵体2的油冷却器24依次连通可使得箱体3无需设置多个进水口和多个出水口，只设置一个冷却水进口301和一个冷却水出口302即可满足水冷系统的需要，即只需一个外接的进水管和一个外接的出水管即可满足水冷系统的需要，从而增加集成式泵站100的集成度和便利性。
冷却水进口301和冷却水出口302设在箱体3的同一侧板上，从而可减少外接的进水管和外接的出水管分别配合在冷却水进口301和冷却水出口302内时的占地空间，也可使得电机的水冷管路、变频器的水冷管路和泵体2的油冷却器24中的一部分管路位于箱体3内，从而不易被损坏。具体地，冷却水进口301和冷却水出口302均设在第四侧板36上。即冷却水进口301和冷却水出口302设在箱体3远离泵体2的一端，从而可使得冷却水管配合在冷却水进口301和冷却水出口302内时不会增加在第一方向上的占用空间，从而便于集成式泵站100适用于狭小的空间。例如，冷却水进口301和冷却水出口302设在箱体3的后端部，由此，可使得冷却水管配合在冷却水进口301和冷却水出口302内时不会增加在左右方向上的占用空间，从而便于集成式泵站100适于狭小的空间。
冷却水进口301和冷却水出口302位于第四侧板36的下端部，由此可使得冷却水进口301和冷却水出口302外泄的水滴不会滴落在集成式泵站100的零部件上，从而可防止损坏水滴损坏集成式泵站100的零部件。
如图1和图2所示，在一些实施例中，箱体3内设有多个隔爆腔，隔爆腔的进口设在第一侧板33上，第一侧板33上设有多个隔爆腔门，多个隔爆腔门一一对应地封盖多个隔爆腔。变频器包括多个模块，多个模块一一对应的可拆卸地安装在多个隔爆腔中。即每个模块设在一个隔爆腔内，各个模块之间通过工业总线连接，多个模块中的每一者设在不同的隔爆腔内，从而使得每个模块可以分别进行拆装，从而提高维护的便利性和设备安全。
如图1和图2所示，在一些实施例中，隔爆腔包括第一隔爆腔、第二隔爆腔、第三隔爆腔和第四隔爆腔。第一侧板33上设有封盖第一隔爆腔的第一隔爆腔门41、封盖第二隔爆腔的第二隔爆腔门42、封盖第三隔爆腔的第三隔爆腔门43和封盖第四隔爆腔的第四隔爆腔门44。
变频器包括滤波器模块、充电单元模块、直流整流单元模块和逆变单元模块。滤波器模块可拆卸地设在第一隔爆腔内，充电单元模块可拆卸地设在第二隔爆腔内，直流整流单元模块可拆卸地设在第三隔爆腔内，逆变单元模块可拆卸地设在第四隔爆腔内。将变频器分为滤波器模块、充电单元模块、直流整流单元模块和逆变单元模块可分别对上 述模块进行独立拆卸，从而便于变频器的安装和维护。
如图1和图2所示，在一些实施例中，控制器包括控制面板5，控制面板5设在第一侧板33上，控制面板5上设有控制按钮和控制显示屏。由此可利用控制按钮来对电机进行控制，通过控制显示屏来观察电机运行情况。
变频器包括变频面板6，变频面板6设在第一侧板33上，控变频面板6上设有变频按钮和变频显示屏。通过变频显示屏可以观察变频器的工作参数和工作情况，通过变频按钮可直接更改变频器的工作参数，从而提高更改变频器的工作参数的便利性。
如图1和图2所示，在一些实施例中，第一侧板33包括朝向上方的倾斜部331，倾斜部331的上沿3311相对其下沿3312在第一方向上邻近第二侧板，控制面板5和变频面板6设在倾斜部上。具体地，箱体3上设有倾斜向上的贯穿孔，贯穿孔贯穿第一侧板33和顶板31，贯穿孔的底壁位于第一侧板33上且邻近顶板31的一侧，贯穿孔的顶壁位于顶板31上且邻近第一侧板33的一侧，倾斜部331的下沿3312与贯穿孔的底壁相连，倾斜部331的上沿3311与贯穿孔的顶壁相连。制面板5和变频面板6位于朝向上方的倾斜部331上可使得控制面板5和变频面板6位于人体更舒适的观看视角和操作位置，进而便于工作人员观察控制显示屏和变频显示屏并便于对控制按钮和变频按钮进行操作。
倾斜部331和第一隔爆腔的进口位于第二隔爆腔的进口、第三隔爆腔的进口和第四隔爆腔的进口的上方。具体地，倾斜部331位于第一侧板33的上半部，第一隔爆腔的进口开设在第一侧板33的上半部，第二隔爆腔的进口、第三隔爆腔的进口和第四隔爆腔的进口开设在第一侧板33的下半部。从而可使得多个隔爆腔更加紧凑的设在箱体3内，进而增加集成式泵站100的集成度。例如，倾斜部331位于第一隔爆腔的后侧，控制面板5和变频面板6在前后方向上排列布置，控制面板5位于变频面板6的后侧。
如图1和图4所示，在一些实施例中，箱体3上设有电缆输入口303和电缆输出口304，电缆输入口303上设有输入插头，电缆输出口304上设有输出插头，变频器和电机串联后与控制器和泵体的油泵电机并联接入输入插头和输出插头之间。由此，只需在箱体3上设有一个电缆输入口303和一个电缆输出口304且电缆输入口303上设有一个输入插头、电缆输出口304上设有一个输出插头即可满足对电机、变频器、控制器和泵体2的油泵电机进行供电，只需在箱体3上设有一个电缆输入口303和一个电缆输出口304可减少外接电缆的数量，从而减少外接电缆的占用空间，进而增加集成式泵站100的集成度。具体地，输入插头通过接线与变频器的输出端相连，变频器的输出端与电机的输出端相连。输入插头通过接线与控制器的输入端相连，输入插头通过接线与泵体2的油泵电机的输入端相连，油泵电机的输出端与输出插头相连。
如图1和图4所示，在一些实施例中，电缆输入口303开设在第四侧板36的上部，电缆输出口304开设在第四侧板36的下部。箱体3内具有接线腔，接线腔的开口设在第四侧板36的上部，第四侧板36上设有封盖接线腔的开口的接线腔门45。接线腔内设有变频器和控制器的接线柱，电缆输入口303和接线腔的开口设在第四侧板36的上部便于进行接线，从而便于变频器和控制器与泵体电路电连接。
电缆输入口303和电缆输出口304开设在第四侧板36上，即电缆输入口303和电缆输出口304开设在箱体3远离泵体2的一端，从而可使得外接电缆配合在输入插头和输出插头内时不会增加在第一方向上的占用空间，从而便于集成式泵站100易与在第二方向上移动。例如，电缆输入口303和电缆输出口304设在箱体3的后端部，由此，可使得外接电缆配合在输入插头和输出插头内时不会增加在左右方向上的占用空间。
