Description

Technical Field

[0001] The utility model belongs to the technical field of fire-fighting equipment, and particularly relates to a large-flow emergency drainage device. Background Art

[0002] With the development of science and technology, people's lives are becoming more and more convenient and their quality of life is getting higher and higher, but they still have to face the invasion of natural disasters at any time. Among them, floods are one of the most common natural disasters for humans. When a disaster occurs, fire rescue personnel usually use large-flow drainage equipment to pump out water to minimize the casualties and property losses caused by floods. At present, there are mainly two types of drainage equipment on the market, one is a parent-child structure drainage vehicle, and the other is a pipe rack drainage vehicle. The former provides hydraulic power to the drainage sub-vehicle through the main vehicle, and the drainage sub-vehicle moves to the target location for drainage. However, the main vehicle and the sub-vehicle cannot be too far apart due to the connection of the hydraulic pipe, and the drainage sub-vehicle needs to be close to pump water, which has a great risk of falling into the water. The latter is directly connected to the target location through a pipe rack. Similarly, if the distance is too far, there will not be enough pipes to be laid. Although both have the advantages of fast driving, convenient use, no need to go into the water, and easy shifting, when facing harsh geographical environments such as mud, swamps, river beaches, and underground facilities such as underground garages, due to the limitations of the vehicle body and power, drainage operations can only be carried out within a certain range. If the accumulated water location is too far away from the drainage point, the drainage vehicle will be useless, making the rescue difficult; in addition, the above two types of drainage vehicles generally adopt the mode of hydraulic power driving the drainage pump, and the engine power causes certain losses during the transmission process, which is not the optimal structural type.

[0003] In the existing technologies, such as the "a lightweight all-terrain drainage pump truck" provided by China Invention Application Announcement No. CN116971472A, and the "a crawler-type integrated flood control and drainage vehicle-mounted mobile pump" disclosed by China Utility Model Patent Authorization Publication No. CN217260370U, and the "an emergency flood control and drainage vehicle suitable for various terrain and road conditions" disclosed by China Invention Application Announcement No. CN104553747A, all have many of the above-mentioned problems.

[0004] In view of the above situation, it is necessary to design an emergency drainage device with large flow, high head, autonomous movement and drainage, adaptability to various complex environments and high safety. To this end, the applicant has made a useful design, and the technical solution to be introduced below was produced in this context. Utility Model Content

[0011] In another specific embodiment of the present invention, the pumping mechanism is constructed as a "Y"-shaped structure, and the pumping mechanism is formed with a pumping end and a pair of drainage ends connected to the pumping end. A pumping impeller is provided in the pumping mechanism near the pumping end, and a pumping impeller drive rod is formed on the pumping impeller. One end of the pumping impeller drive rod extends out of the pumping mechanism and is connected to the main shaft of the drive mechanism.

[0020] The technical innovation of the present invention lies in that a telescopic turning mechanism 4 is rotatably provided above the aforementioned vehicle beam 2, and a control box 1 and a pumping mechanism 6 are respectively provided on the aforementioned telescopic turning mechanism 4. A driving mechanism 5 is provided in the aforementioned control box 1, and the aforementioned pumping mechanism 6 is transmission-connected to the driving mechanism 5.

The cylinder 23 is provided with a cylinder column 231. The end of the cylinder column 231 is hinged to the bottom of the slide 42. The end of the cylinder 23 away from the cylinder column 231 is hinged to the beam 2. The cylinder 23 drives the cylinder column 231 to push the slide 42 to perform telescopic movement, thereby pushing the bottom plate 41 to rotate around the articulated shaft 22. A support seat 24 is provided at a position below one end of the bottom plate 41 of the aforementioned beam 2 for supporting the bottom plate 41. A baffle 21 is provided upward at the end of the aforementioned beam 2 away from the pumping mechanism 6. A side of the aforementioned baffle 21 away from the pumping mechanism 6 is formed with a hook 211. During actual use, the self-loading and unloading fire truck is connected to the aforementioned hook 211 through the arm hook and pulls one end of the entire drainage device to lift and drag it into the car or push the drainage device out of the car and place it steadily on the ground.

[0021] Furthermore, a group of pulleys 421 are respectively provided on the front and rear edges of the aforementioned skateboard 42, and the aforementioned slide rod 42 is slidably set in the skateboard 42 through the pulleys 421. A pumping mechanism fixing seat 43 is provided on the aforementioned skateboard 42, and the aforementioned pumping mechanism 6 is fixedly installed on the pumping mechanism fixing seat 43.

[0022] Furthermore, the aforementioned crawler mechanism 3 includes a circle of crawler tracks 31, a set of crawler support wheels 33, a crawler driven wheel 32, a crawler driving wheel 34 and an oil motor 341 for driving the crawler driving wheel 34 to rotate.

[0023] The drive mechanism 5 includes an engine 51, a flywheel housing 52 drivingly connected to the engine 51, a transfer case 53 drivingly connected to the flywheel housing 52, a hydraulic pump 54 drivingly connected to the transfer case 53, and a main shaft 55 drivingly connected to the transfer case 53. The main shaft 55 is drivingly connected to the pumping mechanism 6. The flywheel housing 52 is used to transmit and disconnect transmission to the transfer case 53. The transfer case 53 is used to drive the hydraulic pump 54 alone, the main shaft 55 alone, or both the hydraulic pump 54 and the main shaft 55 simultaneously. The hydraulic pump 54 is connected to the oil motor 341 and the oil cylinder 23 via a distributor. The hydraulic pump 54 supplies oil to the oil motor 341 alone, to the oil cylinder 23 alone, or to both the oil motor 341 and the oil cylinder 23 simultaneously through the distributor. The control box 1 also includes auxiliary equipment such as an oil tank, a hydraulic tank, and a battery, all of which are conventional in the art and will not be described in detail here.

[0024] See also Figure 3 The pumping mechanism 6 is configured in a Y-shaped structure, comprising a pumping end 61 and a pair of drain ends 62 connected to the pumping end 61. A pumping impeller 64 is disposed within the pumping mechanism 6 near the pumping end 61. An impeller drive rod 63 is disposed on the impeller 64.

Specifically, the impeller drive rod 63 is connected to the main shaft 55 via a coupling.

[0025] Please continue reading Figures 1 to 3 During driving, the oil cylinder 23 pulls the slide plate 42 in a retracted state and prevents the slide plate 42 from moving. The drive mechanism 5 drives the flywheel case 52 and the transfer case 53 in sequence through the engine 51, so that the hydraulic pump 54 works and supplies oil to the oil motor 341. The oil motor 341 rotates, causing the crawler track 33 to rotate to achieve the purpose of driving. Figure 1When drainage is required, the drainage vehicle is first driven to the target location, and then the flywheel box 52 and the transfer case 53 are driven in sequence by the aforementioned engine 51, so that the hydraulic pump 54 is activated to supply oil to the oil cylinder 23. The aforementioned oil cylinder column 231 extends forward and pushes the slide 42 and the control box 1, drive mechanism 5 and pumping mechanism 6 above the slide 42 to slide along the bottom plate 41 for a distance. The aforementioned oil cylinder column 231 continues to extend and, when the slide 42 can no longer slide, the bottom plate 41, the slide 42 and the control box 1, drive mechanism 5 and pumping mechanism 6 above the slide 42 are pushed forward. The box 1, the driving mechanism 5 and the pumping mechanism 6 slide out of the bottom plate 41 and rotate clockwise around the hinge shaft 22. At this time, the pumping end 61 of the pumping mechanism 6 is inserted into the water, and the flywheel box 52 and the transfer case 53 are driven in turn by the engine 51 to rotate the main shaft 55. The main shaft 55 drives the pumping impeller drive rod 63 and the pumping impeller 64 to rotate. Water enters the pumping mechanism 6 from the pumping end 61 and is discharged from the drainage end 62. The water is connected to the pumping end 62 through a pipe to lead the pumped water to a distant place, thereby realizing the pumping work.
