Description

Technical Field

[0001] This utility model relates to the technical field of fully mechanized water pump trucks, specifically a drainage mechanism for a fully mechanized water pump truck. Background Technology

[0002] A fully mechanized water pump truck is a fire truck equipped with a water pump and firefighting equipment. Its main function is to draw water from fire hydrants or other water sources and transport it to the fire scene for firefighting via hoses. Water pump trucks typically do not require an onboard water source, instead utilizing on-site water sources for firefighting, making them widely applicable in cities and towns with narrow roads. The drainage mechanism is one of the most important components of a water pump truck, used for drainage operations. Existing water pump truck drainage mechanisms utilize fixed water pumps and drainage pipes, and the pump position cannot be adjusted, making it unsuitable for special situations where the pump's placement is uncertain. Therefore, we propose a drainage mechanism for fully mechanized water pump trucks to address the aforementioned problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a drainage mechanism for a fully mechanized water pump truck, including a body 1, a hook 17 and a servo motor 18. The four corners of the lower part of the body 1 are equipped with movable wheels 2, and the lower side of the body 1 is fixed with a traction ring 3, which can facilitate the traction and movement of the water pump truck. The two ends of the front and rear sides of the body 1 are fixed with connecting blocks 4, and threaded rods 5 are threadedly connected to the connecting blocks 4. The bottom of the threaded rods 5 is fixed with a support base plate 6. The use of four sets of threaded rods 5 and support base plates 6 can facilitate the stable support of the water pump truck, so as to ensure the stable use of the water pump truck.

[0020] Please see Figure 1-4 The vehicle body 1 has an internal cavity 9, and a slot 10 is formed on the upper surface of the vehicle body 1. A top cover 7 is provided on the top of the vehicle body 1, and a rubber retaining ring 8 connected to the slot 10 is glued to the bottom of the top cover 7. A drain pipe 11 is provided in the middle of the side of the vehicle body 1 away from the traction ring 3. A sewage pipe 12 is provided on the side of the vehicle body 1 to the lower right of the drain pipe 11. A side plate 13 is fixed on the upper side of the side of the vehicle body 1, and a movable column 14 is connected to the side plate 13. The movable column 14 and the side plate 13 are connected by a bearing 24. There are two sets of side plates 13 to facilitate the rotation of the movable column 14 on the side plate 13. A crossbar 15 is fixed on the top of the movable column 14, and a movable frame 16 is provided on the surface of the crossbar 15. A hook 17 is fixed on the bottom of the movable frame 16. The movable frame 16 and the crossbar 15 are connected by a sliding connection, and the movable frame 16 and the rotating screw 19 are connected by a threaded connection. The movable frame 16 can slide on the crossbar 15 to adjust the position of the water pump. A servo motor 18 is fixed at the top of the movable column 14, and a rotating screw 19 is fixed at the output end of the servo motor 18. A gear 20 is fixed at the bottom of the movable column 14. A slide groove 21 is opened on the side of the vehicle body 1 below the side plate 13, and a limiting tooth block 23 is provided on the slide groove 21. An adjusting screw 22 located below the side plate 13 is rotatably connected to the limiting tooth block 23. The limiting tooth block 23 and the slide groove 21 on the surface of the vehicle body 1 form a snap-fit ​​sliding connection, and the connection between the limiting tooth block 23 and the adjusting screw 22 is a threaded connection. The limiting tooth block 23 and the gear 20 below the movable column 14 form a snap-fit ​​connection. The adjusting screw 22 can drive the threaded movement of the limiting tooth block 23, which facilitates the snap-fit ​​and fixing of the limiting tooth block 23 and the tooth block 20, and facilitates the positioning of the movable column 14 after rotation.

[0021] Working principle: First, when using the device, move it to the place where it is needed. When using the device, the threaded rod 5 on the side of the vehicle body 1 can be rotated to make the threaded rod 5 move downward on the connecting block 4 so that the support plate 6 can contact the ground, which facilitates the stable use of the device. The vehicle body 1 has an inner cavity 9 that can receive the sewage discharged from the fully mechanized mining operation. A water pump can also be placed inside for drainage. When draining water, the hand chain hoist can be suspended on the hook 17 below the movable frame 16, and the water pump can be fixed on the hook on the other side of the hand chain hoist for lifting and use.

[0022] In use, the movable column 14 can be rotated to rotate on the side plate 13, which facilitates the adjustment of the water pump's position. After adjustment, the adjusting screw 22 can be rotated to drive the limiting tooth block 23 to slide on the slide groove 21 on the surface of the vehicle body 1, and engage with the gear 20 at the bottom of the movable column 14, so that the movable column 14 can be positioned after rotation. A servo motor 18 is installed on the top of the movable column 14. The servo motor 18 can rotate the lead screw 19 and the movable frame 16 to move threadedly, so that the movable frame 16 can slide on the crossbar 15, thereby facilitating the adjustment of the position of the water pump below and improving the effectiveness of the device. This is the operating principle of the drainage mechanism of the fully mechanized water pump truck.
