Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting facilities, in particular to a novel excess water discharge device. Background Art

[0002] Fire is the most common, most prominent and harmful disaster in real life. It is a major problem directly related to the safety of people's lives and property. When fixed fire-fighting facilities cannot complete the fire-fighting operation, our fire trucks are needed to implement the fire-fighting operation, and our fire truck water pump plays a key role like the human heart. Fire pumps are mainly used to transport liquids, pressurize the liquids and output them to meet the needs of fire-fighting operations.

[0003] After a fire is extinguished, the fire truck needs to discharge the remaining water in the water pipe in time for the next use, especially in the extremely cold northern regions. If the remaining water in the pipe is not discharged in time after the fire-fighting operation, the remaining water will freeze in the waterway and water pump, causing the water pump to freeze and crack under extremely cold conditions, damaging the water pump structure and causing permanent damage, which will in turn affect the subsequent fire-fighting duty of the fire truck.

[0004] Traditionally, after a fire truck has completed the firefighting operation, it is necessary to manually open the residual water drain valve of the fire truck to drain the residual water in the waterway of the fire truck, and then manually close the residual water drain valve after the residual water in the waterway of the fire truck has been drained. This manual residual water drain device of the fire truck needs to be manually operated by the staff after the firefighting operation is completed, which affects the efficiency of the fire truck. In addition, occasionally, the staff forgets to open the residual water drain valve or closes the residual water drain valve before the residual water in the waterway of the fire truck has been drained. Especially in the northern winter, the residual water in the fire truck will freeze, which will cause serious consequences such as damage to related equipment.

[0005] Therefore, a novel residual water discharge device is proposed to solve the current shortcomings. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the defects of the above-mentioned technology and provide a novel residual water discharge device.

[0007] In order to solve the above technical problems, the technical solution provided by the utility model is a new type of residual water discharge device: including a water tank, an air tank, a water pump and a controller;

[0008] The water tank is connected to the water pump through a water pipe, a pneumatic switch is provided on the water pipe, the output end of the water pump is connected to at least one water hose interface with a valve, the output port of the water pump is connected to a drain pipe, and the drain pipe is connected to a residual water pneumatic valve;

[0009] The gas tank is connected to the controller through an air pipe. The controller is provided with an opening air pipe 1 and a closing air pipe 1 connected to the pneumatic switch. The opening air pipe 1 is connected to a closing air pipe 2 connected to the residual water pneumatic valve. The closing air pipe 1 is connected to an opening air pipe 2 connected to the residual water pneumatic valve.

[0010] As an improvement, a manual valve is further included, and the manual valve is arranged at the tail end of the discharge pipe.

[0011] The advantages of the utility model compared with the prior art are:

[0012] 1. By opening and closing the air pipe, the linkage setting of the residual water pneumatic valve and the pneumatic switch is realized. The reverse opening and closing control of the residual water pneumatic valve can be realized while the start switch is opened and closed, and the residual water in the pipeline can be automatically discharged, which can avoid the situation of forgetting to discharge the residual water or the residual water is not completely discharged. There is no need for real-time inspection by the staff, which simplifies the staff's operation of draining the residual water;

[0013] 2. The residual water discharge device has a simple structure and is easy to implement. The residual water discharge is automatically controlled through the linkage control setting of the residual water pneumatic valve and the pneumatic switch, which facilitates the operation of discharging residual water and can effectively avoid the situation where the operating errors of the staff affect the normal use of the water pump.

In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0018] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components must be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0019] In the description of the embodiments of the utility model, "plurality" means at least 2.

[0020] In the description of the utility model embodiments, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.

[0021] Combined with Figure 1 As shown, a novel residual water discharge device includes a water tank 1, an air tank 2, a water pump 3 and a controller 4; in specific implementation, the water tank 1, the air tank 2, the water pump 3 and the controller 4 are all prior arts. Specifically, the water tank 1 and the air tank 2 are both arranged on the vehicle body, and the controller 4 is arranged at the rear end of the vehicle body. At the same time, the water pump 3 is electrically connected to the controller 4, and the start and stop of the water pump 3 can be controlled by the controller 4.

[0022] The water tank 1 is connected to the water pump 3 through the water pipe 5, and the water in the water tank 1 can be transported to the water hose interface 7 with a valve through the water pump 5, and the water can be sprayed under pressure through the water hose;

[0023] The water pipe 5 is provided with a pneumatic switch 6, which is arranged between the water pump 3 and the water tank 1. By starting the on-off operation of the switch 6, the flow and blocking between the water in the water tank 1 and the water pump 3 can be achieved.

[0024] The output end of the water pump 3 is connected to at least one water hose interface 7 with a valve. During implementation, through the delivery of the water pump 3, a pressurized water spraying operation can be achieved through the water hose connected to the water hose interface 7 with a valve.

[0025] The output port of the water pump 3 is connected to a drain pipe 8, and the drain pipe 8 is connected to a residual water pneumatic valve 9, and the residual water pneumatic valve 9 has a closed state and an open state capable of draining residual water in the water pump;

[0026] The gas tank 2 is connected to the controller 4 through the air pipe 10. The air intake control of each air pipe is realized through the setting of the controller 4, so as to achieve the linkage control of the opening and closing of the pneumatic switch 6 and the residual water pneumatic valve 9.

[0027] The controller 4 is provided with an opening air pipe 11 and a closing air pipe 12 connected to the pneumatic switch 6, and the opening air pipe 11 is connected to the closing air pipe 2 13 connected to the residual water pneumatic valve 9. Specifically, when the controller 4 controls the gas tank 2 to inlet air through the opening air pipe 11, while realizing the opening operation of the start switch 6, air can be inlet through the closing air pipe 2 13 connected to the opening air pipe 11 to control the closing of the residual water pneumatic valve 9, thereby ensuring that pressurized water is provided to the water hose interface 7 with the valve through the water pump 3;

[0028] The closed air pipe 12 is connected to the open air pipe 2 14 connected to the residual water pneumatic valve 9. During implementation, when the controller 4 controls the gas tank 2 to take in air through the closed air pipe 12, the closing operation of the start switch 6 is realized. At the same time, air can be taken in through the open air pipe 2 14 connected to the closed air pipe 12 to control the opening of the residual water pneumatic valve 9, thereby discharging the residual water in the pipeline.

[0029] In the specific implementation, the controller 4 controls the gas tank 2 to intake air through the open air pipe 11, so as to realize the opening of the start switch 6, and since the open air pipe 11 is connected to the closed air pipe 2 13 connected to the residual water pneumatic valve 9, the residual water pneumatic valve 9 is controlled to be in a closed state through the intake of the closed air pipe 2 13. At the same time, the controller 4 controls the start of the water pump 3, and the water hose connected to the water hose interface 7 with a valve can be realized to realize the pressurized water spraying operation;

[0030] After the water spraying operation is completed, the controller 4 controls the gas tank 2 to close the air intake of the air pipe 12 to realize the closing of the start switch 6, and at the same time controls the stopping of the water pump 3 through the controller 4. Moreover, since the closed air pipe 12 is connected with the open air pipe 2 14 connected to the residual water pneumatic valve 9, the residual water pneumatic valve 9 can be controlled to be in an open state through the air intake of the open air pipe 2 14, thereby realizing the discharge of the residual water in the water pump 3 and the pipeline.

[0031] It also includes a manual valve 15, which is arranged at the tail end of the discharge pipe 8. Through the dual setting of the residual water pneumatic valve 9 and the manual valve 15, when the residual water pneumatic valve 9 fails, the residual water in the pipeline can be manually discharged, and it also serves as a guarantee for the fire truck during water suction operation.

[0032] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
