实施例1：
请参照图1，本实施例提供一种城市排水水流加速器，包括水泵1、两端分别连接水泵1的出水口和喷射环4的水泵出水管2、两端分别连接水泵1的出水口和分流排水管7的喷射环4、两端分别连接喷射环4和城市排水管道的分流排水管7，所述的喷射环4为一空心的环，外壳并不相连封闭，环外壳内侧具有喷射缝切口5。
在本实施例中，水泵出水管2用金属制成。可以理解的，在其他实施方式中，水泵出水管2也可以采用塑料制成。
在本实施例中，分流排水管7用金属制成。可以理解的，在其他实施方式中，分流排水管7也可以采用塑料制成。
在本实施例中，喷射环4用金属制成。可以理解的，在其他实施方式中，喷射环4也可以采用塑料制成。
请继续参照图1，在本实施例提供的城市排水水流加速器包括水泵1、水泵出水管2、连接水泵出水口管3、喷射环4、分流排水管7、连接水泵入水口管8、水泵入水口管9和水泵固定座10。请结合图2，喷射环4为空心的环状，喷射环4的外壳并不相连封闭，从而在喷射环4的内侧形成喷射缝隙通道5。喷射环4的外周面开设有与连接水泵出水口管3的一端连接的开口(图未示出)。水泵出水管2的一端与水泵1的出水口连接，水泵出水管2的另一端与连接水泵出水口管3的另一端连接。在本实施例中，水泵出水管2和连接水泵出水口管3通过第一法兰51连接。连接水泵入水口管8的一端与分流排水管7连接。水泵入水口管9与水泵1的进水口连接。连接水泵入水口管8的另一端与水泵入水口管9的另一端连接。在本实施例中，连接水泵入水口管8和水泵入水口管9通过第二法兰52连接。喷射环4的一个侧面与分流排水管7的一端端面连接，使喷射环4内表面限定的空间与分流排水管7连通。在本实施例中，为了解决分流排水管7和喷射环4的直径相差大的问题，在喷射环4与分流排水管7之间连接有连接喷射环管6。可以理解的，如果分流排水管7和喷射环4的直径相差不大，也可以将分流排水管7和喷射环4直接连接。例如：将分流排水管7与喷射环4相连的一端，做成比喷射环4直径稍小的端口进行焊接。水泵固定座10由铁板折弯形成，水泵固定座10的外表面设置有两个挂耳11。水泵固定座10套设在水泵1上，并通过挂耳11对水泵1进行固定。水泵出水管2用金属做成。分流排水管7用金属做成。喷射环4用金属做成。
在使用本实施例提供的城市排水水流加速器时，将分流排水管7远离喷射环4的一端与城市排水管道相接。喷射环4可以接入城市排水管道，也可以不接入城市排水管道。当喷射环4接入城市排水管道时，喷射环4通过法兰与城市排水管道连接，或直接与城市排水管道焊接连接。
当喷射环4不接入城市排水管道时，喷射环4可以置于低洼处。当城市排水管道中水流流速缓慢，无法及时排出时，启动本实施例提供的城市排水水流加速器。水泵1通过分流排水管7将城市排水管道中的水抽出，并输送到喷射环4中。在水泵1产生的压力的作用下，喷射环4中的水通过喷射缝隙切口5喷出。当水通过喷射缝隙切口5喷出时，流速较高，增加了低洼处中水的流速。根据伯努利定律可知，当低洼处中水的流速增加时，低洼处中水的水压变低，从而加快了城市排水管道中水的流速，使得城市排水管道中的水通过分流排水管7快速排出至低洼处。如此增加了城市排水管道中水的排出速度，进而缓解 城市路面积水的问题。
当喷射环4接入城市排水管道时，如果城市排水管道中水流流速缓慢，启动本实施例提供的城市排水水流加速器。水泵1通过分流排水管7将城市排水管道中的水抽出，并输送到喷射环4中。在水泵1产生的压力的作用下，喷射环4中的水通过喷射缝隙切口5喷出。同时，与分流排水管7连接的城市排水管道中的水通过分流排水管7和喷射环4进入与喷射环4连接的城市排水管道中。当水通过喷射缝隙切口5喷出时，流速较高，增加了与喷射环4连接的城市排水管道中的水的流速。根据伯努利定律可知，与喷射环4连接的城市排水管道中的水的流速增加时，其中水的水压变低，使得与分流排水管7连接的城市排水管道中的水能够快速通过分流排水管7进入与喷射环4连接的城市排水管道中，从使城市排水管道中水的流速向前加快，提高了城市排水管道的排水能力，进而缓解城市路面积水的问题。
本实施例提供的城市排水水流加速器在使用时，只需要安装在既有的城市排水管道中即可缓解城市路面积水的问题，无需对城市排水管道进行大规模挖建改造，节约了成本。
实施例2：
请参照图3，本实施例也提供一种城市排水水流加速器。本实施例提供的城市排水水流加速器与实施例1提供的城市排水水流加速器基本相同，不同之处在于，在本实施例中分流排水管7与喷射环4之间不连接。如此使得水泵1能够通过连接水泵入水口管8、水泵入水口管9和分流排水管7在远离喷射环4处抽水，使本实施例提供的城市排水水流加速器的安装和布置具备更大的灵活性。
实施例3：
请参照图1，本实施例提供一种水流加速器，包括水泵1、喷射环4和排水管7。
请结合参照图2，图2为本实施例提供的水流加速器的喷射环4的轴向截面视图。其中，轴向截面是指通过喷射环4的轴线所在平面将喷射环4剖切后呈现的截面。从图2中可以看出，喷射环4具备环状空腔410。喷射环4上具备缝隙5，缝隙5将环状空腔410与外界连通。水泵1的出水口与喷射环4连接，并且水泵1的出水口与环状空腔410连通。排水管7与水泵1的进水口连接。排水管7的一个端部与喷射环4连接。进一步的，喷射环4的一个侧面与排水管7的一端端面连接，使喷射环4内表面限定的空间与排水管7连通。
在使用本实施例提供的水流加速器时，将排水管7远离喷射环4的一端与城市排水管道相接。喷射环4可以接入城市排水管道，也可以不接入城市排水管道。当喷射环4接入城市排水管道时，喷射环4通过法兰与城市排水管道连接，或直接与城市排水管道焊接连接。
当喷射环4不接入城市排水管道时，喷射环4可以置于低洼处。当城市排水管道中水 流流速缓慢，无法及时排出时，启动本实施例提供的水流加速器。水泵1通过排水管7将城市排水管道中的水抽出，并输送到喷射环4中。在水泵1产生的压力的作用下，喷射环4中的水通过缝隙5喷出。当水通过缝隙5喷出时，流速较高，增加了低洼处中水的流速。根据伯努利定律可知，当低洼处中水的流速增加时，低洼处中水的水压变低，从而加快了城市排水管道中水的流速，使得城市排水管道中的水通过排水管7快速排出至低洼处。如此增加了城市排水管道中水的排出速度，进而缓解城市路面积水的问题。
当喷射环4接入城市排水管道时，如果城市排水管道中水流流速缓慢，启动本实施例提供的水流加速器。水泵1通过排水管7将城市排水管道中的水抽出，并输送到喷射环4中。在水泵1产生的压力的作用下，喷射环4中的水通过缝隙5喷出。同时，与排水管7连接的城市排水管道中的水通过排水管7和喷射环4进入与喷射环4连接的城市排水管道中。当水通过缝隙5喷出时，流速较高，增加了与喷射环4连接的城市排水管道中的水的流速。根据伯努利定律可知，与喷射环4连接的城市排水管道中的水的流速增加时，其中水的水压变低，使得与排水管7连接的城市排水管道中的水能够快速通过排水管7进入与喷射环4连接的城市排水管道中，从使城市排水管道中水的流速向前加快，提高了城市排水管道的排水能力，进而缓解城市路面积水的问题。
本实施例提供的城市排水水流加速器在使用时，只需要安装在既有的城市排水管道中即可缓解城市路面积水的问题，无需对城市排水管道进行大规模挖建改造，节约了成本。
下面对本实施例提供的水流加速器进行进一步说明。
在本实施例中，缝隙5的开口方向与喷射环4的轴线不垂直。如此，使得缝隙5中喷出的水能够更加充分地带动低洼处中的水或城市排水管道中的水沿着排水方向加速，从而进一步提高了城市排水管道的排水能力。可以理解的，在其他实施方式中缝隙5的开口方向也可以与喷射环4的轴线垂直。
在本实施例中，缝隙5为沿喷射环4延伸的环形，这样通过缝隙5能够喷出的水能够成环状的喷出，从而更加高效地带动低洼处中的水或城市排水管道中的水沿着排水方向加速。可以理解的，在其他实施方式中缝隙5也可以不为环形。
在本实施例中，缝隙5位于喷射环4的内周面。这样，当喷射环4接入城市排水管道时，从缝隙5喷出的水能够直接进入城市排水管道中。可以理解的，在其他实施方式中，缝隙5也可以被配置在喷射环4的侧面或外周面上。
在本实施例中，参照图2，在喷射环4的轴向截面上，环状空腔410包括相互连通的第一腔室411和第二腔室412；在远离第一腔室411的方向上，第二腔室412的宽度逐渐减小；缝隙5直接与第一腔室411连通。缝隙5、第一腔室411和第二腔室412是这样形成的。喷射环4的轴向截面轮廓包括第一轮廓边421、第二轮廓边422、第三轮廓边423和第四轮廓 边424；第二轮廓边422和第三轮廓边423分别从第一轮廓边421的两端向下第一轮廓边421的同一侧延伸；在第三轮廓边423的延伸方向上，第三轮廓边423与第一轮廓边421之间的距离逐渐增大；第四轮廓边424从第三轮廓边423远离第一轮廓边421的端部向第一轮廓边421延伸；第四轮廓边424与第二轮廓边422远离第一轮廓边421的一端交错且间隔地布置，以形成缝隙5。第一轮廓边421和第三轮廓边423之间的空间构成第二腔室412。第一轮廓边421、第二轮廓边422和第四轮廓边424之间的空间构成第一腔室411。可选的，第二轮廓边422和第四轮廓边424均为在远离第一轮廓边421的方向上凸出的弧形。可选的，第三轮廓边423还可以包括第一子轮廓边4231和第二子轮廓边4232；第一轮廓边421、第一子轮廓边4231、第二子轮廓边4232和第四轮廓边424依次连接；第一子轮廓边4231与第一轮廓边421的夹角大于第二子轮廓边4232的延长线与第一轮廓边421的延长线的夹角。
在本实施例中，参照图1，水泵1的出水口通过出水管30与环状空腔410连通。出水管30包括第一出水管2和第二出水管3；第一出水管2和第二出水管3通过第一法兰51相互连接；第一出水管2与水泵1的出水口连接；第二出水管3与喷射环4连接。可以理解的，在其他实施方式中，水泵1的出水口也可以通过其他方式与环状空腔410连通，例如将喷射环4直接设置在水泵1的出水口处，使水泵1的出水口与环状空腔410连通。
在本实施例中，参照图1，排水管7通过进水管70与水泵1的进水口连接。进水管70包括第一进水管8和第二进水管9；第一进水管8和第二进水管9通过第二法兰52相互连接；第一进水管8与排水管7连接；第二进水管9与水泵1的进水口连接。可以理解的，在其他实施方式中，水泵1的进水口也可以通过其他方式与排水管7连接，例如水泵1的进水口直接与排水管7连接。
在本实施例中，为了解决排水管7和喷射环4的直径相差大的问题，在喷射环4与排水管7之间连接有环管6。可以理解的，如果排水管7和喷射环4的直径相差不大，也可以将排水管7和喷射环4直接连接。例如：将排水管7与喷射环4相连的一端，做成比喷射环4直径稍小的端口进行焊接。
在本实施例中，参照图1，为了更好的固定水泵1，还设置有固定座10。固定座10由铁板折弯形成，固定座10的外表面设置有两个挂耳11。固定座10套设在水泵1上，并通过挂耳11对水泵1进行固定。
实施例4：
请参照图3，本实施例也提供一种水流加速器。本实施例提供的水流加速器与实施例3提供的水流加速器基本相同，不同之处在于，在本实施例中排水管7与喷射环4之间不连接。如此使得水泵1能够通过进水管70和排水管7在远离喷射环4处抽水，使本实施例提 供的水流加速器的安装和布置具备更大的灵活性。
显然，本发明的上述实施例仅仅是为了清楚说明本发明所作的举例，而并非是对本发明的实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明权利要求的保护范围之内。
