Description

Technical Field

[0001] The invention relates to the technical field of fire fighting equipment, and in particular to an electric-controlled fire fighting cannon head capable of manually adjusting flow rate during a spraying process. Background Art

[0002] The electronically controlled fire monitor is a high-end product in modern firefighting equipment, integrating electronic control, automatic tracking, positioning and spraying technology, and is mainly used for fire fighting in large buildings, petrochemicals, airports, warehouses, etc. Its core function is to remotely or automatically control the rotation, pitch and spray of the fire monitor through an electronic control system to achieve accurate and efficient fire extinguishing.

[0003] However, the electronically controlled fire monitors commonly used in the market have certain limitations in design, mainly manifested in the singleness of the delivery pipeline and the fragility of the control system. These fire monitors are usually equipped with only one delivery pipeline for delivering fire extinguishing media, such as water or foam, and the control of the pipeline is completely dependent on the solenoid valve. The solenoid valve receives control signals through electronic circuits to achieve opening and closing and flow regulation functions. This design can meet basic fire extinguishing needs under normal circumstances, but when encountering extreme situations such as fires, the solenoid valve and its control circuit are extremely susceptible to damage, such as the circuit being burned or the solenoid valve itself failing due to high temperature. Once this happens, the entire fire monitor will lose its function and will not be able to continue the fire extinguishing operation, which may cause the fire to spread, causing greater property losses and casualties. In addition, due to the lack of the function of manually adjusting the flow, operators cannot flexibly adjust the flow of the fire extinguishing medium according to the actual situation when facing a complex and changeable fire environment, which further limits the fire extinguishing effect.

[0023] Specifically, the regulating component 6 includes a valve body 61, a sealing unit 62 for sealing the inside of the valve body 61, and an execution unit 63 for driving the sealing unit 62. The valve body 61 is fixedly arranged on one of the branch delivery pipes 4. The valve body 61 is a prior art component, and its specific internal structure will not be introduced in detail. The sealing unit 62 is arranged on the valve body 61. Its function is to realize the opening or closing of the valve body 61 under the drive of the execution unit 63, so as to control the liquid flow rate flowing through the branch delivery pipe 4. The execution unit 63 is arranged on the sealing unit 62.

[0024] Specifically, the blocking unit 62 includes a support shell 62-1, a spring 62-2, two slide grooves 62-3, a movable plate 62-4, a valve stem 62-5 and a blocking head 62-6. The support shell 62-1 is fixedly arranged on the outer top of the valve body 61. The support shell 62-1 provides a stable operating environment for each component inside it. The spring 62-2 is located in the support shell 62-1, and the bottom end of the spring 62-2 is fixedly connected to the outer top of the valve body 61. The main function of the spring 62-2 is to provide a reset force to ensure that the blocking unit 62 can automatically return to the initial position after manual operation. The two slide grooves 62-3 are respectively fixedly arranged on the left and right sides of the support shell 62-1, and the movable plate 62-4 is respectively slidably connected to the two slide grooves 62-3, and The bottom of the movable plate 62-4 is fixedly connected to the top of the spring 62-2, the top of the valve stem 62-5 is fixedly set at the bottom of the movable plate 62-4, and the valve stem 62-5 is located on the inner side of the spring 62-2. The valve stem 62-5 is movable through the top of the valve body 61 and extends to the inside of the valve body 61. The plugging head 62-6 is fixedly set at the bottom of the valve stem 62-5. The movable plate 62-4 can move up and down in the slide groove 62-3. Through its connection with the spring 62-2, it transmits the force of manual operation to drive the valve stem 62-5 and the plugging head 62-6 to perform corresponding actions. The actuator 63 is set at the top of the supporting shell 62-1. The actuator 63 is the manually operated part, through which the operator can apply force to drive the action of the plugging unit 62. In the case that the solenoid valve 5 fails or other automatic control functions cannot work normally, the actuator 63 ensures that the fire monitor head 1 can still adjust the flow through manual operation.

[0025] Specifically, the execution unit 63 includes a limiting cylinder 63-1, a driving rod 63-2, a driving plate 63-3, a fixing cylinder 63-4 and a locking rod 63-5. The limiting cylinder 63-1 is fixedly arranged on the outer top of the supporting shell 62-1. The driving rod 63-2 is slidably connected with the inner wall of the limiting cylinder 63-1, and the driving rod 63-2 is movable through the top of the supporting shell 62-1. The limiting cylinder 63-1 provides limiting and guiding functions for the driving rod 63-2 inside it, ensuring that the driving rod 63-2 can maintain the correct linear motion trajectory during operation. A plurality of adjustment holes are opened on the driving rod 63-2. The driving plate 63-3 is fixedly arranged on the bottom end of the driving rod 63-2, and the driving plate 63-3 In contact with the movable plate 62-4, the left and right sides of the limit cylinder 63-1 are provided with fixing holes matching the adjustment holes, and the adjustment holes are used to cooperate with the fixing holes on the limit cylinder 63-1 to achieve different position locking, thereby realizing multi-stage flow adjustment of the fire monitor head 1, and the fixing cylinder 63-4 is fixedly arranged on the left side outside the limit cylinder 63-1, and the locking rod 63-5 is respectively movably passed through the fixing hole on the limit cylinder 63-1 and any one of the adjustment holes on the driving rod 63-2, and is movably inserted into the fixing cylinder 63-4, and the locking rod 63-5 is used to lock the position of the driving rod 63-2 to ensure that after adjusting the flow, the blocking head 62-6 can remain in the set position to provide stable flow control.

[0026] Specifically, a locking unit 64 is further provided in the adjustment assembly 6 for enhancing the connection stability between the fixing cylinder 63 - 4 and the locking rod 63 - 5 .

[0027] Specifically, the locking unit 64 includes a first magnet 64-1 and a second magnet 64-2. The first magnet 64-1 is fixedly arranged at one end of the locking rod 63-5 close to the fixed tube 63-4. The first magnet 64-1 is a movable part. The second magnet 64-2 is fixedly arranged in the fixed tube 63-4. The second magnet 64-2 is a fixed part, and the first magnet 64-1 and the second magnet 64-2 attract each other.

[0028] The magnetic attraction between the first magnet 64-1 and the second magnet 64-2 enhances the connection stability between the locking rod 63-5 and the fixed cylinder 63-4 to prevent loosening or displacement, and the magnetic connection allows quick locking and release, which facilitates the operator to quickly adjust the position of the drive rod 63-2 when necessary, so that the fire gun head 1 quickly reaches the maximum flow.

[0029] Specifically, the locking unit 64 also includes a connecting rod 64-3, a plurality of rubber clamping balls 64-4, a groove 64-5 and a clamping slot 64-6. The connecting rod 64-3 is fixedly arranged on the right side of the second magnet 64-2, and a plurality of arc-shaped rubber clamping balls 64-4 are evenly arranged on the connecting rod 64-3. The arc-shaped rubber clamping balls 64-4 are elastic themselves. A groove 64-5 matching the connecting rod 64-3 is opened on the left side of the first magnet 64-1, and a plurality of clamping slots 64-6 matching the rubber clamping balls 64-4 are opened inside the groove 64-5.

[0030] When the locking rod 63-5 is inserted into the fixing tube 63-4, the first magnet 64-1 and the second magnet 64-2 attract each other, and at the same time the connecting rod 64-3 enters into the groove 64-5 of the first magnet 64-1, and the rubber card ball 64-4 on the connecting rod 64-3 is carded into the card slot 64-6 of the groove 64-5 of the first magnet 64-1, realizing double locking.

[0031] Specifically, the gap between the valve stem 62 - 5 and the valve body 61 is filled with a sealing gasket, which ensures the sealing between the valve stem 62 - 5 and the valve body 61 , prevents fluid leakage, and ensures the normal operation and safety of the valve.

[0032] Specifically, a handle is fixedly provided at the top of the driving rod 63 - 2 , and the handle facilitates the operator to operate the driving rod 63 - 2 .

[0033] Specifically, the number of the adjustment holes on the driving rod 63 - 2 is at least three, and the number of the adjustment holes can be changed according to the demand for flow regulation.

[0034] Working principle: The electric-controlled fire cannon head integrates the solenoid valve 5 control and the manual adjustment component 6, realizing a dual flow adjustment mechanism. In normal operation, the solenoid valve 5 controls the on-off of the delivery branch pipe 4, adjusts the flow of the fire-fighting medium, and thus controls the spray intensity of the cannon head. Once the solenoid valve 5 fails, the manual adjustment component 6 starts immediately to ensure the continuity of the fire-fighting operation. The core of the manual adjustment component 6 is the plugging unit 62, and its plugging head 62-6 is in a closed state under normal conditions. During operation, first pull out the locking rod 63-5 to release the constraint of the spring 62-2, so that the plugging head 62-6 is adjustable. Then, press the drive rod 63-2 downward, and through the limiting action of the limiting cylinder 63-1, the drive rod 63-2 drives the drive plate 63-3 to move downward, pressing the movable plate 62-4 and the spring 62-2. After the spring 62-2 is compressed, it pushes the movable plate 62-4, the valve stem 62-5 and the plugging head 62-6 to move downward together, realizing multi-stage flow precision control. After the adjustment is completed, align the corresponding adjustment hole on the driving rod 63-2 with the fixing hole of the limiting cylinder 63-1, and insert the locking rod 63-5 of the locking unit 64 into the fixing cylinder 63-4 through the adjustment hole and the fixing hole. The connecting rod 64-3 enters the groove 64-5 of the first magnet 64-1 to achieve preliminary fixation. The fixation is further strengthened by the magnetic attraction between the first magnet 64-1 and the second magnet 64-2. Turn the locking rod 63-5 so that the slot 64-6 in the groove 64-5 of the locking rod 63-5 corresponds to the slot 64-6 of the rubber card ball 64-4, and the card ball enters the slot 64-6 to achieve final fixation, ensuring the stability of the locking rod 63-5. If you need to quickly adjust to the maximum flow rate, just pull the locking rod 63-5 outward to separate the locking rod 63-5 from the fixing hole and the adjustment hole. At the same time, the magnetic attraction is released, the rubber card ball 64-4 exits the card slot 64-6, and the spring 62-2 quickly resets to achieve rapid release and flow adjustment. This design ensures the flexibility and stability of flow adjustment and provides continuous and accurate flow control for firefighting operations.
