[0002] Water pumps are used for drainage operations, specifically in urban flood control and drainage, natural disaster relief, agriculture, and industry. Mobile drainage equipment is equipped with water pumps and is suitable for various special scenarios, performing particularly well in emergency rescue and complex working conditions. When heavy rain causes severe flooding in low-lying urban areas, roads, underground parking lots, etc., mobile drainage equipment can quickly reach the scene to carry out emergency drainage operations, rapidly restore traffic order, and reduce the impact of flooding on residents' lives and property.

[0003] In some drainage systems, the water pump is fixed to a mounting bracket. When the pump is draining water, it exerts a reaction force on the bracket, which can cause the pump to operate unevenly and, in severe cases, damage the bracket. Furthermore, because the pump is fixed to the bracket, the direction of the hose it is connected to is also fixed, making it difficult to deploy the hose. Utility Model Content

However, this application is not limited to these embodiments. In the following description, specific details such as particular configurations and components are provided merely to aid in a comprehensive understanding of the embodiments of this application. Therefore, those skilled in the art should understand that various changes and modifications can be made to the embodiments described herein without departing from the scope of protection of this application. Furthermore, for clarity and brevity, descriptions of known functions and structures have been omitted.

[0034] This application provides a water pump attitude adjustment device for mounting a water pump and adjusting its horizontal angle attitude to switch the pump to different spraying angles. The water pump attitude adjustment device includes a central support, multiple swing arms, and a drive element. The swing arms are connected to the water pump and are rotatably connected to the central support. The multiple swing arms are evenly distributed around the central support. The drive element drives the multiple swing arms to rotate synchronously relative to the central support to different angular positions. Based on the above water pump attitude adjustment device, on the one hand, the angle attitude of the water pump can be adjusted to switch the pump to different spraying angles. On the other hand, because the multiple swing arms are evenly distributed around the central support, the reaction forces of each water pump during operation partially cancel each other out, which helps to improve the stress condition of the installation structure.

Each connecting arm corresponds to a swing arm. The first end of each connecting arm is rotatably connected to the sliding member, and the second end is rotatably connected to the swing arm. The driving element is a telescopic driving element, with its driving end connected to the sliding member. As the driving element telescopically drives the sliding member to slide on the central support, the multiple connecting arms synchronously rotate and adjust the multiple swing arms accordingly. Furthermore, a slide rail is provided on the central support. The sliding member is adapted to the slide rail and can slide along the extension direction of the slide rail. The slide rail on the central support can be used to limit the sliding member to slide in a set direction.

[0036] The driving element is a telescopic driving element, which can be set as a hydraulic cylinder, pneumatic cylinder, electric cylinder, etc. For any swing arm, it forms a related motion with the sliding part through the connecting arm. When the driving element extends or retracts, its driving end drives the sliding part to move, all the connecting arms move synchronously, and all the swing arms rotate synchronously.

[0037] The central support includes a rod-shaped support body and multiple connecting parts distributed around the support body; a slide rail is arranged on the support body and extends along the length of the support body; each connecting part corresponds to a swing arm, and the swing arms are rotatably connected to the corresponding connecting parts. The number N of swing arms can be designed as 2, 3, 4, 5, 6, 7, etc.
