[0041] The following describes in detail the overall structure, working principle, and technical effects of the fire monitor device 010 provided by this utility model through embodiments and in conjunction with the accompanying drawings.

[0042] Please refer to Figures 1-2 The fire monitor device 010 provided by this utility model can stably carry out firefighting work under various complex terrain conditions.

[0043] This utility model proposes a fire monitor device 010, comprising:

[0044] The main body 100 has a water tank 200 inside and a nozzle 300 on its surface. The main body 100 is movable relative to the ground.

[0045] Water supply equipment 400 is installed on the main body 100 and is used to supply water to the water tank 200 and the nozzle 300;

[0046] Four support leg structures 500 are provided. Two support leg structures 500 are provided on each side of the main body 100 at intervals. The support leg structures 500 are retractable relative to the ground and are used to support the main body 100.

[0047] Understandably, by setting up a movable body 100 relative to the ground, the body 100 can be easily and quickly moved to a designated location; by setting up a water supply device 400 and a sprinkler head 300 on the body 100, the water supply device 400 can supply water to the sprinkler head 300, enabling the sprinkler head 300 to perform firefighting work at the designated location; by setting up a water supply device 400 and a water tank 200, the water supply device 400 supplies water to the water tank 200, and by using the water tank 200 as a counterweight, the recoil force generated by the fire monitor device 010 during operation is reduced; by setting up four support legs 500 on the body 100, when the working scene has various complex terrain conditions, such as uneven ground, slopes, etc., the four legs can provide support. The extendable leg structure 500 allows the fire monitor device 010 to adapt to different terrains, ensuring stable placement and normal operation in various environments and expanding its application range. Simultaneously, by incorporating a water tank 200 and four support leg structures 500 on the main body 100, the weight of the water tank 200 after filling with water effectively reduces the recoil force generated by the nozzle 300 during water spray. The support leg structures 500 provide stable support points; the combined effect of these two structures further balances the recoil force, minimizing its impact on the stability of the fire monitor device 010. This ensures the nozzle 300 remains stable during high-flow-rate spraying operations, improving the accuracy and repeatability of the spray.

[0048] In this embodiment, the fire monitor device 010 includes a nozzle 300.

[0049] In this embodiment, please refer to Figures 1-4 The nozzle 300 is mounted on the body 100. The output end of the nozzle 300 is equipped with an openable nozzle so that the output end of the nozzle 300 sprays out a large flow of water jet or a small flow of mist, which can avoid the waste of fire extinguishing agent or water while ensuring fire extinguishing.

[0050] In this embodiment, please refer to Figures 1-2 The nozzle 300 has an upper housing 330 and a lower housing 340 at its output end, and the upper housing 330 and the lower housing 340 are openable and closable. Furthermore, the nozzle 300 is also provided with a driving member, which is used to drive the upper housing 330 and / or the lower housing 340 to open and close. The degree of opening and closing between the upper housing 330 and the lower housing 340 determines the form of the water column output from the output end of the nozzle 300.

[0051] Alternatively, please refer to Figure 2 The driving component includes an electric actuator 350, the output end of which is connected to the upper housing 330 and the lower housing 340 to control the opening degree between the upper housing 330 and the lower housing 340. For example, the electric actuator 350 drives the upper housing 330 to rotate toward the lower housing 340, or the electric actuator 350 drives the lower housing 340 to rotate toward the upper housing 330, or the electric actuator 350 simultaneously drives the lower housing 340 and the upper housing 330 to rotate, thereby controlling the opening degree between the upper housing 330 and the lower housing 340.

[0052] Of course, in some embodiments, the driving component may also be a drive motor and a gear structure. The output end of the drive motor is connected to the upper housing 330 or the lower housing 340 through the gear structure, thereby driving the opening and closing action of the upper housing 330 or the lower housing 340.

[0053] The sprinkler head 300 is connected to an external circuit so that the external circuit provides power to the electric components of the sprinkler head 300, enabling the sprinkler head 300 to perform fire-fighting operations with high flow rates.

[0054] In this embodiment, the fire monitor device 010 includes a body 100.

[0055] In this embodiment, a water tank 200 is provided inside the main body 100, a nozzle 300 is provided on the main body 100, and the main body 100 is movable relative to the ground.

[0056] Alternatively, please refer to Figures 1-2The main body 100 includes a first box 110 and a second box 120 connected to each other. The first box 110 is provided with a water tank 200. The second box 120 is provided with a water supply device 400. The second box 120 is provided with at least one first water inlet 121. The water inlet of the water supply device 400 is connected to at least one first water inlet 121. The water outlet 421 of the water supply device 400 is connected to the input end of the nozzle 300 and the water tank 200.

[0057] The first box 110 and the second box 120 are frame structures.

[0058] Optionally, the second housing 120 has a larger first water inlet 121 on its rear side; the second housing 120 also has two smaller first water inlets 121 on its opposite left and right sides. It is understood that, on the one hand, providing multiple first water inlets 121 can increase the water inlet area into the water supply equipment 400, ensuring flow supply; on the other hand, symmetrically arranging the smaller first water inlets 121 allows the water flow to enter the water supply equipment 400 symmetrically and evenly, making the water flow more stable.

[0059] In this embodiment, the nozzle 300 is disposed on the top of the second housing 120, and the output end of the nozzle 300 faces the first housing 110.

[0060] In this embodiment, please refer to Figures 1-2 The top of the second housing 120 is also provided with at least a spare nozzle 310 and a cannon head 320. The top of the second housing 120 can be fixed with a bracket to fix the spare nozzle 310 and the cannon head 320.

[0061] In this embodiment, please refer to Figures 1-4 The bottom of the main body 100 is also provided with a moving device 140 to allow the main body 100 to be movable relative to the ground. The moving device 140 includes a roller mechanism located on opposite sides of the main body 100. Of course, in other embodiments, the moving device 140 may also be a tracked moving mechanism located on opposite sides of the main body 100.

[0062] In this embodiment, please refer to Figures 1-4 The main body 100 is also provided with a trailer bracket 130, which is fixedly connected to the main body 100 and the axle of the roller mechanism. The trailer bracket 130 is used to connect the fire monitor device 010 to the trailer so that the trailer can drive the fire monitor device 010 to the working position.

[0063] In this embodiment, the fire monitor device 010 includes a water tank 200.

[0064] In this embodiment, please refer to Figures 2-4A water tank 200 is installed inside the first housing 110, and the water tank 200 is located at the center of the main body 100; please refer to Figures 1-2 The water supply equipment 400 is connected to the water tank 200 via a connecting pipe 210, which is connected to the main body 100. A first valve 211 is installed on the connecting pipe 210, and the first valve 211 is used to open and close the connecting pipe 210. Please refer to... Figure 2 The first box 110 of the main body 100 is also provided with a drain outlet, which is connected to the water tank 200. A second valve 220 is provided at the drain outlet, which is used to open and close the drain outlet.

[0065] In this embodiment, a detection element is provided inside the water tank 200 to detect the water level inside the water tank 200. Optionally, the detection element can be a water level indicator.

[0066] Understandably, closing the second valve 220 and opening the first valve 211 allows water to be supplied to the water tank 200 via the water supply equipment 400. During the water supply process, the operator needs to closely monitor the water level in the water tank 200, which can be observed using a detection device. When the water level reaches the full water level mark of the water tank 200, the first valve 211 should be closed immediately to stop water supply and prevent overflow.

[0067] It is worth mentioning that the water tank 200 of the fire monitor device 010 can be drained during transportation by opening the second valve 220 to drain the water from the tank 200. After draining the water tank 200, the weight of the fire monitor device 010 is reduced, making it easier to transport. Furthermore, the reduced weight of the fire monitor device 010 meets the national standard requirement that "trailers under 3.5 tons do not need to be equipped with active braking devices," which not only reduces the manufacturing cost of the equipment but also simplifies the related operations and requirements during transportation, improving the convenience and economy of the equipment in the transportation process.

[0068] In this embodiment, please refer to Figure 4 The water tank 200 is provided with multiple baffles 230, and the baffles 230 are provided with multiple through holes 231; some baffles 230 are arranged along a first direction, and other baffles 230 are arranged along a second direction, and the baffles 230 arranged along the first direction are connected to the baffles 230 arranged along the second direction; wherein, the first direction and the second direction are arranged perpendicularly, the first direction is the transverse direction of the water tank 200, and the second direction is the longitudinal direction of the water tank.

[0069] Alternatively, the multiple liquid baffles 230 may be arranged only along the first direction; or the multiple liquid baffles 230 may be arranged only along the second direction.

[0070] Understandably, the baffle plate 230 divides the water tank 200 into interconnected sections. When the water tank 200 is full of liquid, this design allows the various sections inside the water tank 200 to effectively reduce the swaying amplitude of the liquid in a swaying environment.

[0071] Alternatively, the water tank 200 can be made of high-strength, corrosion-resistant, and lightweight PP (Polypropylene), which not only ensures the durability of the water tank 200 and extends the service life of the equipment, but also achieves good weight-bearing performance without adding too much weight, thus improving the overall cost-effectiveness of the equipment.

[0072] In this embodiment, the fire monitor device 010 includes a water supply device 400.

[0073] Among them, the water supply equipment 400 is used to connect the water supply hose and pump to ensure that water can be supplied smoothly to the fire monitor.

[0074] In this embodiment, please refer to Figure 4 The water supply equipment 400 includes a first rear water inlet pipe 410 and a second water inlet pipe 420. The first rear water inlet pipe 410 is connected to at least one first water inlet 121, the input end of the nozzle 300, and the water tank 200. The second water inlet pipe 420 is provided with an outlet 421, a second water inlet 422, and a third water inlet 423. The second water inlet 422 is connected to the first rear water inlet pipe 410, the third water inlet 423 is connected to the water tank 200, and the outlet 421 is connected to the input end of the nozzle 300.

[0075] The third water inlet 423 is connected to the water tank 200 via a connecting pipe 210.

[0076] Please refer to Figure 4 The first water inlet pipe and at least one first water inlet 121 are connected through a check valve 430.

[0077] In this embodiment, the fire monitor device 010 includes four support leg structures 500.

[0078] In this embodiment, please refer to Figure 3 Two spaced-apart support leg structures 500 are provided on opposite sides of the main body 100. The support leg structures 500 are retractable relative to the ground and are used to support the main body 100.

[0079] Two support leg structures 500 are located on opposite sides of the first housing 110 and fixed to the first housing 110, while the other two support leg structures 500 are located on opposite sides of the second housing 120 and fixed to the second housing 120.

[0080] In this embodiment, please refer to Figures 1-2The outrigger structure 500 includes a connecting seat 510, an outrigger 520, and a driving device 530. The connecting seat 510 is connected to the body 100. The connecting seat 510 has a telescopic cavity. The outrigger 520 is disposed in the telescopic cavity. The output end of the driving device 530 is connected to the outrigger 520 for transmission. The driving device 530 is used to drive the outrigger 520 to extend and retract along the telescopic cavity and to lock the outrigger 520.

[0081] Optionally, the drive unit 530 includes at least a rocker arm and a transmission system that are connected in a transmission manner, and the transmission system is also connected in a transmission manner to the outrigger 520. In this case, the outrigger 520 is a manually adjustable external outrigger 520.

[0082] Optionally, the drive unit 530 includes an electric drive component. Then, the support leg 520 is an electrically adjustable external support leg 520.

[0083] Optionally, the drive unit 530 includes a hydraulic drive component. Then, the outrigger 520 is a hydraulically adjustable external outrigger 520.

[0084] Understandably, the operator uses the drive unit 530 to slowly extend the four outriggers 520. During the extension process, the operator observes the extension of the outriggers 520 and the balance of the main body 100 to make initial adjustments to the extension length of the outriggers 520. Once the outriggers 520 have extended to a certain extent, the operator uses the drive unit 530 to finely adjust the height of each outrigger 520 to keep the main body 100 horizontal. After the adjustment is completed, the drive unit 530 locks the outriggers 520 to ensure that they will not move during subsequent operations.

[0085] In this embodiment, the outrigger 520 has a support rotatably mounted at one end near the ground. Optionally, the support is hinged to the outrigger 520.

[0086] The surface of the support is designed to fit different ground surfaces to increase friction and stability.

[0087] In this embodiment, the fire monitor device 010 includes a control panel. The control panel is equipped with indicator lights and various control buttons for displaying the various operating statuses of the fire monitor device 010 and for operation control.

[0088] The working principle and process of the fire monitor device 010 provided in this embodiment of the utility model are as follows:

[0089] First: The operator operates the drive device 530 to adjust the height of each outrigger 520 to keep the main body 100 horizontal. After adjustment, the drive device 530 locks the outriggers 520 to ensure they do not move during subsequent operations.

[0090] Second: Install the nozzle 300 onto the body 100, ensuring a secure installation to prevent it from falling off during operation. After installation, plug it in to provide power to the electric components of the nozzle 300.

[0091] Third: Connect one end of the water supply hose to the first rear water inlet pipe 410 of the water supply equipment 400 through the first water inlet 121, and connect the other end of the water supply hose to the high-flow water supply equipment 400; ensure a tight connection to prevent leakage. At the same time, connect the battery to the charging device to charge the battery to ensure that it has sufficient power during equipment operation.

[0092] Fourth: Close the second valve 220 and open the first valve 211 to fill the water tank 200 with water through the water supply equipment 400 and connecting pipe 210. During the filling process, the operator needs to closely monitor the water level in the water tank 200, which can be observed by setting a detection device. When the water level reaches the full water level mark of the water tank 200, close the first valve 211 in time to stop filling the water and prevent water from overflowing.

[0093] Fifth: After completing all the above operations, check whether each part of the equipment is working properly. When the equipment is in normal working condition, the red indicator light on the control panel will light up, indicating that the fire monitor device 010 is ready to receive signals and start working. At this time, the operator can send a working signal to the fire monitor device 010 through the external control device. After receiving the signal, the fire monitor device 010 will work according to the set program to make the nozzle 300 spray water and other extinguishing agents.

[0094] In summary, the fire monitor device 010 provided in this embodiment of the present invention, by setting a movable body 100 relative to the ground, allows for convenient and rapid movement of the body 100 to a designated location; by setting a water supply device 400 and a nozzle 300 on the body 100, the water supply device 400 can supply water to the nozzle 300, enabling the nozzle 300 to perform firefighting work on the designated location; by setting a water supply device 400 and a water tank 200, the water supply device 400 supplies water to the water tank 200, and by using the water tank 200 as a counterweight, the recoil force generated when the fire monitor device 010 is working is reduced; by setting four support legs 500 on the body 100, it can withstand various complex terrain conditions, such as uneven ground. The four extendable support legs 500, designed to accommodate slopes and other terrain features, allow the fire monitor 010 to adapt to different terrains, ensuring stable placement and normal operation in various environments and expanding its application range. Simultaneously, by incorporating a water tank 200 and four support legs 500 on the main body 100, the weight of the water tank 200 after filling with water effectively reduces the recoil force generated by the nozzle 300 during water spray. The support legs 500 provide stable support points, and their combined effect further balances the recoil force, minimizing its impact on the stability of the fire monitor 010. This ensures the nozzle 300 remains stable during high-flow-rate spraying operations, improving the accuracy and repeatability of the spray.

[0095] 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.
