Description

Technical Field

[0001] The present application relates to the technical field of fire-fighting equipment, and in particular to a water treatment device for field operations of remote water supply and drainage vehicles. Background Art

[0002] Due to the distance from clean water sources and the complexity of field roads, the water supply for field firefighting and rescue (such as forests) has always been a pain point in the industry. Currently, water trucks are mainly used to draw water from distant fire hydrants or fire wells and then transport it to the work site to refill firefighting trucks with fire water. The biggest problem is the long round-trip distance and the limited amount of water transported each time. Vehicles with large-capacity water tanks are difficult to enter work sites with harsh conditions due to their size and narrow field roads. It is difficult to meet the firefighting water supply needs of firefighting trucks, resulting in short effective operation time of firefighting trucks and poor firefighting effects. In addition, the water quality of field water sources contains many impurities and cannot meet the water quality cleanliness requirements of firefighting trucks' fire pumps, resulting in the inability of field remote water supply and drainage vehicles to draw water locally from nearby ponds, lakes, rivers, etc. Utility Model Content

Detailed implementation manners

[0026] The following are specific embodiments of the present application and, in combination with the accompanying drawings, further describe the technical solutions of the present application. However, the present application is not limited to these embodiments. In the following description, specific details such as specific configurations and components are provided only to help a comprehensive understanding of the embodiments of the present application. Therefore, those skilled in the art should clearly understand that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Additionally, descriptions of known functions and structures are omitted for clarity and conciseness.

[0027] It should be noted that, without conflict, the implementation manners and features in the implementation manners of the present application can be combined with each other.

[0028] The present application provides a water treatment device for the field operation of a remote water supply and drainage vehicle. A vehicle for remote water supply and drainage in the field can draw water locally from a nearby pond, lake, river, etc., and then, after being treated by the water treatment device provided by the present application, it becomes fire-fighting water that can be used by a fire main battle vehicle. The following specifically describes this water treatment device with reference to the accompanying drawings.

[0029] Refer to Figures 1 - 5 , the water treatment device for the field operation of a remote water supply and drainage vehicle includes: an outer housing 10, in which a first-stage filtration structure 21, a second-stage filtration structure 22, and a third-stage filtration structure 23 are arranged. The outer housing 10 forms a water inlet tank 11, a first water chamber 12, and a second water chamber 13 in its internal space; the water inlet tank 11 is located above the first water chamber 12, and the second water chamber 13 is located on the side of the water inlet tank 11 and the first water chamber 12; a water inlet 14 is arranged in the water inlet tank 11, and a water outlet 15 is arranged in the second water chamber 13. The first-stage filtration structure 21 is located at a predetermined height inside the outer housing 10 and is arranged between the water inlet tank 11 and the first water chamber 12; the second-stage filtration structure 22 is arranged between the first water chamber 12 and the second water chamber 13; the third-stage filtration structure 23 is arranged at the water outlet 15 inside the second water chamber 13; inside the first water chamber 12, a water flow baffle 24 is provided on the side of the second-stage filtration structure 22.

[0030] When the water treatment device is working, water enters from the water inlet 14, and the sewage first enters the water inlet tank 11. The water inlet tank 11 is located above the first water chamber 12, and the water in the water inlet tank 11 passes through the first-stage filtration structure 21 and then enters the lower first water chamber 12; the second-stage filtration structure 22 is arranged between the first water chamber 12 and the second water chamber 13, and the water in the first water chamber 12 is filtered by the second-stage filtration structure 22 and then enters the second water chamber 13. Finally, the water in the second water chamber 13 passes through the third-stage filtration structure 23 to reach the water outlet 15 and is discharged through the water outlet 15. Thus, the sewage entering the water treatment device from the water inlet 14 is discharged from the water outlet 15 after passing through the three-stage filtration structures of the first-stage filtration structure 21, the second-stage filtration structure 22, and the third-stage filtration structure 23. Further, inside the first water chamber 12, a water flow baffle 24 is provided on the side of the second-stage filtration structure 22. On the water inlet side of the second-stage filtration structure 22, the water flow baffle 24 can change the direction of the water flow and reduce the water flow speed, facilitating the sedimentation of impurities to the bottom.

[0031] In an embodiment of the present application, the filtration aperture of the first-stage filtration structure is 5 mm; the filtration aperture of the second-stage filtration structure is 3 mm; the filtration aperture of the third-stage filtration structure 23 is 0.5 mm.

[0032] It should be understood that due to the structural characteristics of the on-vehicle pond water supply pump, the maximum outer diameter of the particulate matter of the impurities in the water supplied by the water supply pump does not exceed 20 mm. Thus, the filtration aperture of the first-stage filtration structure 21 of the water treatment device is designed to be 5 mm, which can allow large floating objects to stay in the upper water inlet tank 11. The filtration aperture of the second-stage filtration structure 22 is designed to be 3 mm, which can further filter smaller floating impurities. Finally, designing the third-stage filtration structure 23 at the water outlet 15 can meet the filtration accuracy requirements for the normal operation of the subsequent pump, and the filtration aperture can be designed to be 0.5 mm.

[0033] In an embodiment of the present application, the first-stage filtration structure, the second-stage filtration structure, and the third-stage filtration structure 23 are all installed in a detachable manner. Here, a replaceable assembly structure is adopted, and the filtration structures with different or the same filtration accuracies can be replaced according to the requirements of subsequent equipment, which is convenient for maintenance. Moreover, it is more flexible in use, and different filtration structures can be used according to different filtration requirements and water qualities.

[0034] Reference Figure 1, within the first water chamber 12, a sub-water chamber 16 is formed between the water flow baffle 24 and the second-stage filtration structure 22. Above the sub-water chamber 16, a first partition plate 25 is provided, and between the second-stage filtration structure 22 and the bottom of the outer housing 10, a second partition plate 26 is provided; the first partition plate 25, the second partition plate 26, and the second-stage filtration structure 22 are used to separate the sub-water chamber 16 and the second water chamber 13; the water flow baffle 24 is joined to the first partition plate 25, and a water flow inlet 17 of the sub-water chamber 16 is formed between the water flow baffle 24 and the bottom of the outer housing 10.

[0035] Specifically, the water flow baffle 24 is arranged on the side of the second-stage filtration structure 22. On both sides of the sub-water chamber 16 are the water flow baffle 24 and the second-stage filtration structure 22 respectively. Above the sub-water chamber 16 is the first partition plate 25, and below is the bottom of the outer housing 10. The sub-water chamber 16 is enclosed by the first partition plate 25, the second-stage filtration structure 22, the second partition plate 26, the water flow baffle 24, and the bottom of the outer housing 10, and a water flow inlet 17 is formed between the water flow baffle 24 and the bottom of the outer housing 10. Water flows into the sub-water chamber 16 through the water flow inlet 17. The water flow baffle 24 can block the water flow, and the space becomes larger after entering the water flow inlet 17. Inside the sub-water chamber 16, the water flow velocity decreases, facilitating the sedimentation of impurities in the water flow.

[0036] In an embodiment of the present application, the water treatment device further includes a flushing pipeline 30. The flushing pipeline 30 is connected to the second water chamber 13 for accessing pressurized water flow or compressed air. The flushing pipeline 30 can introduce high-pressure air or high-pressure water at the outlet of the water pump to flush or vigorously stir the device, enabling the impurities attached to the filtration device to be detached through reverse flushing and restoring the function of the filtration structure.

[0037] Furthermore, the flushing pipeline includes a first flushing pipeline 31 and a second flushing pipeline 32; the first flushing pipeline 31 is connected to the water inlet side of the third-stage filtration structure 23, and the second flushing pipeline 32 is connected to the water outlet side of the third-stage filtration structure 23; a first electric control valve 311 is provided on the first flushing pipeline 31, and a second electric control valve 321 is provided on the second flushing pipeline 32. When the water treatment device is working normally, the controller can control the first electric control valve 311 and the second electric control valve 321 to remain closed. When reverse flushing is required, the first electric control valve 311 is opened to allow pressurized water flow or compressed air to enter the water inlet side of the third-stage filtration structure 23 in the second water chamber 13 from the first flushing pipeline 31, and the second electric control valve 321 is opened to allow pressurized water flow or compressed air to enter the water outlet side of the third-stage filtration structure 23 in the second water chamber 13 from the second flushing pipeline 32. The above flushing pipeline can achieve automatic flushing by means of the first electric control valve 311 and the second electric control valve 321, without manual participation, with a simple structure and good regeneration effect.

[0038] In an embodiment of the present application, a first sewage outlet 41 is provided at the bottom of the water inlet tank 11 and is connected to a first sewage pipeline 42; a second sewage outlet 43 is provided at the bottom of the first water chamber 12 and is connected to a second sewage pipeline 44. The sewage containing impurities remaining after the water in the water inlet tank 11 passes through the first-stage filtration structure can enter the first sewage pipeline 42 through the first sewage outlet 41 and be discharged; the sewage containing impurities remaining after the water in the first water chamber 12 passes through filtration can enter the second sewage pipeline 44 through the second sewage outlet 43 and be discharged. The designed sewage pipelines here can discharge the sewage in the water treatment device regularly.

[0039] Further referring to Figure 1 and Figure 3 , the first sewage pipeline 42 and the second sewage pipeline 44 are joined and connected together, and a drain valve 45 is provided on the main pipeline after the confluence; a check valve 46 for restricting the flow of sewage in the discharge direction is provided on the second sewage pipeline 44. When the water treatment device is working normally, the drain valve 45 remains closed. When sewage discharge is required, the drain valve 45 is opened, and the first sewage pipeline 42 and the second sewage pipeline 44 can discharge sewage simultaneously. In addition, the check valve 46 can achieve one-way cut-off during sewage discharge, restrict the flow of sewage in the discharge direction, and prevent the sewage from flowing back into the water inlet chamber through the sewage pipeline.

[0040] Further referring to Figure 1 and Figure 3 , at a position near the bottoms of the first water chamber 12 and the second water chamber 13, a communication port 18 is opened on the partition between the first water chamber 12 and the second water chamber 13, and a sluice gate 19 that can be opened unidirectionally from the second water chamber 13 to the first water chamber 12 side is provided on the communication port 18. The communication port 18 is used to connect the first water chamber 12 and the second water chamber 13, and the sluice gate 19 on the communication port 18 can be opened unidirectionally from the second water chamber 13 to the first water chamber 12 side; during sewage discharge, the sluice gate 19 is opened, and the sewage in the second water chamber 13 can enter the first water chamber 12 through the communication port 18 and be discharged through the second sewage outlet 43 into the second sewage pipeline 44. When working normally, the water in the first water chamber 12 passes through the second-stage filtration structure 22 and enters the second water chamber 13, the sluice gate 19 remains closed, and the water in the second water chamber 13 cannot flow back into the first water chamber 12 through the communication port 18. Here, the sluice gate 19 is set to open unidirectionally, similar to a check valve.

[0041] In an embodiment of the present application, an exhaust pipeline 50 is provided in the water inlet tank 11, and the lower end of the exhaust pipeline 50 is communicated with the first water chamber 12. The exhaust pipeline 50 can be used to discharge the excess air in the first water chamber 12 and reduce the filtration resistance. In Figure 4 the structure shown, a liquid level gauge 60 is further provided in the water treatment device, and the liquid level gauge 60 passes through the first water chamber 12 and the water inlet tank 11.

[0042] The present application provides a water treatment device for field operation of a remote water supply and drainage vehicle, enabling the vehicle for remote water supply and drainage in the field to draw water locally from nearby ponds, lakes, rivers, etc., and then, after being treated by the water treatment device, it becomes fire-fighting water that can be used by the main fire-fighting vehicle. The water treatment device provided by the present application can perform three-stage filtration and efficient sedimentation on the field water source and can provide fire-fighting water. In a further improved technical solution, the water treatment device is also equipped with a filter regeneration component, which introduces high-pressure air through an electric control valve or high-pressure water at the outlet of the water pump to flush or vigorously stir the device, so that the impurities attached to the filter device are detached through reverse flushing, and the function of the filter device is restored. In a further improved technical solution, the water treatment device is also equipped with a first sewage pipeline and a second sewage pipeline. The first sewage pipeline can discharge the floating substances in the water inlet tank, and the second sewage pipeline can discharge the impurities in the first water chamber and the second water chamber.
