[0024] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0025] Please refer to Figure 1 This embodiment provides a controllable device for displaying the liquid level in a fire truck tank, comprising: Controller 11 and at least one tank assembly 12; The tank assembly 12 includes a storage tank 100, a detection mechanism 200, and at least one indicator light group 300; the indicator light group 300 includes multiple liquid level lights 310, which are arranged sequentially along the height direction of the storage tank 100; the detection mechanism 200 and the multiple liquid level lights 310 are all electrically connected to the controller 11. The detection unit 200 is configured to detect the liquid level data of the fluid in the storage tank 100; The controller 11 is configured to turn on or off the level indicator 310 facing the fluid in the storage tank 100 to indicate the level status of the storage tank 100.

[0026] The fire truck tank level display and controllable device of this solution includes a display light group 300 comprising multiple level lights 310 arranged sequentially along the height of the storage tank 100. This allows the position of each level light 310 to indicate the corresponding level. The detection mechanism 200 and the multiple level lights 310 are electrically connected to the controller 11. The detection mechanism 200 detects the level of the fluid in the storage tank 100; the controller 11 illuminates or extinguishes the level light 310 directly opposite the fluid in the storage tank 100 to indicate the level status of the storage tank 100. This method displays the level data detected by the detection mechanism 200 on the storage tank 100 intuitively and efficiently through multiple level lights 310, allowing the operator to clearly understand the current fluid content in the storage tank 100 and thus conduct targeted firefighting operations. Therefore, the fire truck tank level display and controllable device has the advantages of high accuracy, good display effect, and low cost.

[0027] Please continue reading. Figure 1 , Figure 2 , Figure 3 and Figure 4 To learn more about the structural details of the controllable device for displaying the liquid level in the fire truck tank.

[0028] In an optional embodiment, the detection mechanism 200 is a pressure sensor. Optionally, a float-type pressure sensor is selected, which has the advantages of simple structure, convenient operation, and good stability.

[0029] It is not difficult to understand that in other embodiments of this utility model, the detection mechanism 200 may also be selected from other types of pressure sensors; or it may not use a pressure sensor, but instead use other types of liquid level detection mechanisms, such as radar level gauges or other structures. This is just an example and is not limited to any specific example.

[0030] In an optional embodiment, the liquid level lamp 310 is an LED lamp. LED lamps have the advantages of clear display, high brightness, and low power consumption. It is easy to understand that in other embodiments of this utility model, the liquid level lamp 310 can also be other forms of lamp body 312; this is merely an example.

[0031] In an optional embodiment, the storage tank 100 is either a foam tank 110 or a water tank 120. Further, in this embodiment, the fire truck tank level display and controllable device includes a foam tank 110 and a water tank 120. The foam tank 110 has a single cap on its top. The water tank 120 has two caps on its top to improve water filling efficiency. Furthermore, the foam tank 110 has an indicator light assembly 300, and the water tank 120 also has a separate indicator light assembly 300.

[0032] like Figure 2 and Figure 3 As shown, it should be noted that in this embodiment, the indicator light group 300 of the foam tank 110 is arranged adjacent to the indicator light group 300 of the water tank 120. The indicator light group 300 of the foam tank 110 has five liquid level lights 310 arranged vertically in sequence.

[0033] Furthermore, from top to bottom of the foam tank 110, the four upper liquid level lights 310 are yellow, and the lowermost liquid level light 310 is red. When the detection mechanism 200 detects the liquid level data at the corresponding height, the corresponding liquid level light 310 illuminates; otherwise, the light at that height is off. The lowermost liquid level light 310 being red serves as a warning that the liquid level in the storage tank 100 is low and the fluid content is decreasing, reminding the operator to replenish the fire-fighting fluid in a timely manner.

[0034] The indicator light assembly 300 of the water tank 120 has five level lights 310 arranged sequentially at an upward angle. This distinguishes it from the indicator light assembly 300 of the foam tank 110 to avoid confusion with the level display of the foam tank 110.

[0035] Furthermore, from top to bottom of the water tank 120, the four upper level lights 310 are green, and the lowermost level light 310 is red. When the detection mechanism 200 detects the level data at the corresponding height, the corresponding level light 310 illuminates; otherwise, the light at that height is off. The lowermost level light 310 being red serves as a warning that the current level in the storage tank 100 is low and the fluid content is decreasing, reminding the operator to replenish the fire-fighting fluid in a timely manner.

[0036] In an optional embodiment, in the tank assembly 12, an indicator light group 300 is provided on each side of the storage tank 100 along the width direction. This enables simultaneous display of liquid level changes on both sides of the storage tank 100, thereby improving the convenience and efficiency of liquid level display.

[0037] In an optional implementation, the controller 11 is a PLC unit. It is readily understood that in other embodiments of this invention, the controller 11 may also be of other forms, such as a microcontroller; this is merely an example.

[0038] like Figure 2 , Figure 3 and Figure 4 As shown, in an optional embodiment, the level lights 310 are detachably mounted on the storage tank 100. Furthermore, the level lights 310 are electrically connected to the controller 11 via quick-release connectors, thus improving the ease of installation and removal of the level lights 310 and facilitating protection and maintenance.

[0039] In an optional embodiment, the level lamp 310 includes a connecting plate 311 and a lamp body 312. The connecting plate 311 is respectively disposed at both ends of the lamp body 312 along its length. The storage tank 100 is provided with a mating groove 101, and the connecting plate 311 is detachably disposed at the bottom of the mating groove 101 so that the connecting plate 311 is flush with the surface of the storage tank 100. This ensures better cleanliness of the surfaces of the level lamp 310 and the storage tank 100.

[0040] Furthermore, the lamp body 312 protrudes slightly from the outer wall of the storage tank 100, so that the liquid level lamp 310 has a wider light emission range, which is beneficial to improving the indication effect of the liquid level lamp 310.

[0041] In an optional embodiment, a connector 410 is also included. The bottom of the mating groove 101 has a mating part 420. The connecting plate 311 is provided with a connecting hole. The connector 410 passes through the connecting hole and connects with the mating part 420, so that the connecting plate 311 is fastened to the bottom of the mating groove 101. This connection method has the advantages of simple structure and convenient assembly and disassembly.

[0042] In an optional embodiment, the mating part 420 is threadedly connected to the connecting part 410. Optionally, in this embodiment, the connecting part 410 is a bolt, and the mating part 420 is a pre-installed nut.

[0043] The vehicle body is equipped with a left-side liquid level display and a right-side liquid level display that are connected to the controller 11. The monitoring data is displayed on the screen through the controller 11 via the detection mechanism 200, which makes it convenient for firefighters to monitor the liquid volume in the water tank 120 and the foam tank 110, and ensure the fire extinguishing efficiency at the fire rescue site.

[0044] Furthermore, the two sides of the fire truck storage tank 100 can display the liquid level in the extinguishing agent tank in real time and have a device for quick replacement of LED liquid level lights 310. The tank side is equipped with multiple sets of LED liquid level lights 310, which indicate the approximate liquid level in the extinguishing agent tank. This can fully meet the needs of firefighters to accurately obtain the remaining amount of extinguishing agent during remote vehicle use, thereby improving the efficiency of fire fighting and rescue at the fire scene.

[0045] It should be noted that, in this embodiment, the liquid level of the airport fire truck should be able to display the actual liquid level of the tank more quickly and in real time, so that firefighters can understand the liquid capacity of the fire tank during combat readiness and firefighting. The external storage tank 100 has a large surface area for displaying the level gauge, making it more visible. The liquid level display can also be controlled by PLC and displayed on the control panel 21 in the driver's cab, allowing firefighters to keep track of the status of the extinguishing agent in the tank.

[0046] The tank uses a PLC for real-time display, and the water tank 120 uses red and green (four yellow and one red) displays; the foam displays red and yellow (four green and one red). The airport vehicle tank is manufactured as a single unit with a special structural design that facilitates disassembly and maintenance. If one of the liquid level lights (310) fails, only the faulty one needs to be replaced, which greatly increases the maintenance frequency.

[0047] In summary, this utility model provides a controllable device for displaying the liquid level in a fire truck tank, which has at least the following advantages: Multiple level lights 310 are arranged sequentially along the height of the storage tank 100, so that the level data at the corresponding height can be indicated by the location of the level lights 310. A detection mechanism 200 is used to detect the level data of the fluid in the storage tank 100; a controller 11 is used to turn on or off the level lights 310 directly opposite the fluid in the storage tank 100 to indicate the level status of the storage tank 100. In this way, the level data detected by the detection mechanism 200 is displayed intuitively and efficiently on the storage tank 100 through multiple level lights 310, allowing the operator to clearly know the current fluid content in the storage tank 100 and thus carry out targeted firefighting operations. Such a fire truck tank level display and controllable device has the advantages of high accuracy, good display effect, and low cost.

[0048] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
