Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, specifically to a fixed remote-controlled fire monitor. Background Technology

[0002] Remote-controlled fire monitors receive commands from a remote control or fire control center via an electrical control system. The drive motor rotates the monitor body and adjusts its tilting mechanism to achieve horizontal and vertical rotation. Simultaneously, the control valves regulate the spray pattern of the extinguishing agent, such as direct current spray or mist spray. A fire monitor generally consists of a base, inlet pipe, rotating body, monitor head, monitor barrel, and drive mechanism. It can spray the extinguishing agent to a relatively long distance, covering a large area, and effectively extinguishing fires at a distance.

[0003] CN203408420U discloses a remote-controlled fire monitor, characterized by a water outlet control motor installed inside the barrel behind the muzzle, a vertical steering mechanism connected to the rear end of the barrel, a vertical steering motor mounted on the vertical steering mechanism, an infrared thermometer mounted on the barrel, and a Zigbee wireless communication module I mounted on the infrared thermometer. The vertical steering mechanism is connected to a high-pressure water inlet pipe via a flange, and a solenoid valve is mounted on the high-pressure water inlet pipe. The solenoid valve has a remote control switch, and a mechanical valve is installed at the lower end of the solenoid valve on the high-pressure water inlet pipe for easy maintenance. The high-pressure water inlet pipe is mounted on a horizontal rotating platform, and a horizontal rotating base is mounted below the horizontal rotating platform. The horizontal rotating base is mounted on a cement base, and a horizontal rotating motor is mounted on the cement base. The horizontal rotating motor is equipped with a Zigbee wireless communication module II, and the horizontal rotating motor is connected to the horizontal rotating platform and the horizontal rotating base via a signal line to control the rotation angle of the horizontal rotating platform relative to the horizontal rotating base, thereby achieving precise rotation angle control. The horizontal rotating motor is a stepper motor. This invention enables remote-controlled fire extinguishing. It has a simple structure and is easy to operate. Since the operator is far away from the fire, personal safety is guaranteed.

[0004] While existing technology CN203408420U offers numerous advantages during use, it still suffers from the following problems: its adjustment of the extinguishing agent spray force is not perfect. Because existing fire monitors are directly supplied with water from fire hoses, the spray distance and force are directly affected by the water pressure inside the fire hoses, resulting in insufficient coverage of the extinguishing agent and impacting the fire extinguishing effect. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a fixed remote-controlled fire monitor.

[0006] The technical solution adopted by this utility model to solve its technical problem is a fixed remote-controlled fire monitor, including a fixed plate, a drain pipe, and a cannon barrel. A water supply pipe is inserted and installed inside the fixed plate. A water passage pipe is rotatably installed on one side of the upper outer wall of the water supply pipe. A connecting pipe is inserted and installed on one side of the outer wall of the water passage pipe. A drain pipe is rotatably installed on one end of the outer wall of the connecting pipe. The cannon barrel is set inside the drain pipe. A first support plate is installed on one side of the outer wall of the drain pipe. The first support plate has movable holes arranged in a rectangular array inside. A second support plate is installed on one side of the outer wall of the cannon barrel. A support frame is installed on one side of the inner wall of the drain pipe. A conical column is installed on the outer wall of one end of the support frame. Electric push rods are screwed to the upper and lower outer walls of the first support plate.

[0007] By adopting the above technical solution, the upper end of the water supply pipe is rotatably connected to the water inlet pipe, which is connected to the connecting pipe, and the connecting pipe is rotatably connected to the drain pipe. This multi-stage rotatable connection design allows the fire monitor to flexibly adjust the spray angle in both horizontal and vertical directions, better adapting to the needs of different fire scenarios. The distance between the monitor tube and the drain pipe can be adjusted by an electric push rod, thereby enabling the monitor tube to retract and retract into the drain pipe. At this time, the conical column will penetrate into the monitor tube. Through the overlap between the conical column and the monitor tube, and because the inner diameter of the monitor tube is smaller than the inner diameter of the drain pipe, the fluid can flow from the wide section to the narrow section. Based on Bernoulli's principle, the fluid velocity can be increased, thereby increasing the fluid spray distance and spray force, ensuring the fire extinguishing effect of the fluid on the fire location. Furthermore, by adjusting the movement distance of the monitor tube, the fluid spray distance and spray force can be adjusted to meet different fire application scenarios.

[0008] Specifically, an inlet pipe is inserted and installed on one side of the lower outer wall of the water supply pipe, a flange is installed on the outer wall of one end of the inlet pipe, and a base is screwed to both sides of the lower outer wall of the fixing plate, with fixing holes opened on both sides of the outer wall of the base.

[0009] By adopting the above technical solution, the water inlet pipe can be easily connected to the external water source pipeline through the flange, ensuring that the fire-fighting water can be stably delivered to the inside of the cannon pipe and the cannon head. The staff can use the external bolts to pass through the fixing holes inside the base, so that the device can be firmly installed in the designated position, ensuring that the device will not shake or shift during use.

[0010] Specifically, a first driving mechanism is installed on one side of the outer wall of the water pipe, and a gear is installed on one side of the outer wall of the water supply pipe, with the first driving mechanism meshing with the gear.

[0011] By adopting the above technical solution, the output end coupling of the first drive mechanism is connected to the drive wheel, and the first drive mechanism is controlled by an external controller to drive the drive wheel to rotate. By driving the drive wheel to mesh with the gear, the water pipe can be driven to rotate in a circle at the upper end of the water pipe, thereby enabling the horizontal adjustment of the gun head's orientation position.

[0012] Specifically, a worm gear is installed on one side of the outer wall of the connecting pipe, and a second driving mechanism is installed on one side of the upper outer wall of the water pipe, the second driving mechanism meshing with the worm gear.

[0013] By adopting the above technical solution, the output end coupling of the second drive mechanism is connected to a worm gear, and the second drive mechanism is controlled by an external controller to drive the worm gear to rotate. By driving the worm gear to mesh with the worm wheel, the drain pipe can be driven to rotate circumferentially outside the connecting pipe, thereby enabling vertical adjustment of the gun head's orientation position.

[0014] Specifically, the outer wall of the second support plate is screwed with a rectangular array of limiting rods. The size of the limiting rods is smaller than the size of the movable hole, and the limiting rods are movably installed inside the movable hole.

[0015] By adopting the above technical solution, the limiting rod and the movable hole provide guidance and limiting function for the extension and retraction of the gun barrel, ensuring that the gun barrel will not deviate or shake during the extension and retraction process, thereby improving the stability and reliability of the gun barrel extension and retraction.

[0016] Specifically, a sealing ring is bonded and fixed to one side of the outer wall of the gun barrel, the outer ring of the sealing ring is in contact with the inner wall of the drain pipe, and a gun head is inserted and installed on the outer wall of one end of the gun barrel.

[0017] By adopting the above technical solution, water leakage at the gap between the gun barrel and the drain pipe can be effectively prevented, ensuring that all water flow can be sprayed out from the gun head, improving water utilization and spraying effect, and the fluid inside the gun barrel can be sprayed out through the gun head.

[0018] Specifically, connectors are installed on the upper and lower outer walls of the second support plate, and one end of the electric push rod is screwed to the connector.

[0019] By adopting the above technical solution, the connector ensures the stability of the connection between the second support plate and the push rod part of the electric push rod, ensuring that the power of the electric push rod can be transmitted to the gun barrel, and enabling precise adjustment of the gun barrel's position.

[0020] The beneficial effects of this utility model are:

[0021] (1) The fixed remote-controlled fire monitor described in this utility model can make the fluid flow from a wide section to a narrow section. Based on Bernoulli's principle, it can increase the flow velocity of the fluid, thereby increasing the spray distance and spray force of the fluid and ensuring the fire extinguishing effect of the fluid on the fire location.

[0022] (2) The fixed remote-controlled fire monitor described in this utility model can adjust the spray distance and spray force of the fluid by adjusting the movement distance of the cannon tube according to the electric push rod, so as to meet different fire application scenarios.

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the fixed remote-controlled fire monitor of this utility model includes a fixed plate 1, a drain pipe 2, and a cannon barrel 3. A water supply pipe 11 is inserted and installed inside the fixed plate 1. A water passage pipe 13 is rotatably installed on one side of the upper outer wall of the water supply pipe 11. A connecting pipe 15 is inserted and installed on one side of the outer wall of the water passage pipe 13. A drain pipe 2 is rotatably installed on one end of the outer wall of the connecting pipe 15. The cannon barrel 3 is installed inside the drain pipe 2. A first support plate 21 is installed on one side of the outer wall of the drain pipe 2. The first support plate 21 has movable holes 22 arranged in a rectangular array inside. A second support plate 33 is installed on one side of the outer wall of the cannon barrel 3. A support frame 24 is installed on one side of the inner wall of the drain pipe 2. A conical column 25 is installed on one end of the outer wall of the support frame 24. Electric push rods 23 are screwed to the upper and lower outer walls of the first support plate 21.

[0031] In use, the upper end of the water supply pipe 11 is rotatably connected to the water passage pipe 13, the water passage pipe 13 is connected to the connecting pipe 15, and the connecting pipe 15 is rotatably connected to the drain pipe 2. This multi-stage rotatable connection design allows the fire monitor to flexibly adjust the spray angle in both horizontal and vertical directions, better adapting to the needs of different fire scenarios. The distance between the monitor tube 3 and the drain pipe 2 can be adjusted by the electric push rod 23, thereby enabling the extension and retraction adjustment of the monitor tube 3, allowing the monitor tube 3 to retract into the drain pipe 2. At this time, the conical column 25 will penetrate into the monitor tube 3. Through the overlap between the conical column 25 and the monitor tube 3, and because the inner diameter of the monitor tube 3 is smaller than the inner diameter of the drain pipe 2, the fluid can flow from the wide cross-section to the narrow cross-section. Based on Bernoulli's principle, the fluid velocity can be increased, thereby increasing the fluid spray distance and spray force, ensuring the fire extinguishing effect of the fluid on the fire location. Furthermore, by adjusting the moving distance of the monitor tube 3, the spray distance and spray force of the fluid can be adjusted to meet different fire application scenarios.

[0032] To fix the usage location, for example, such as Figure 1 As shown, a water inlet pipe 16 is inserted and installed on one side of the lower outer wall of the water supply pipe 11. A flange is installed on the outer wall of one end of the water inlet pipe 16. A base 17 is screwed to both sides of the lower outer wall of the fixing plate. Fixing holes are opened on both sides of the outer wall of the base 17.

[0033] During use, the inlet pipe 16 can be easily connected to the external water source pipe through the flange to ensure that the fire water can be stably delivered to the cannon pipe 3 and the cannon head 32. The staff can use the external bolts to pass through the fixing holes inside the base 17 to firmly install the device in the designated position, so as to ensure that the device will not shake or shift during use.

[0034] For the purpose of adjusting the fire extinguishing position, for example, such as Figure 1 As shown, a first drive mechanism 12 is installed on one side of the outer wall of the water pipe 13, and a gear is installed on one side of the outer wall of the water pipe 11, and the first drive mechanism 12 meshes with the gear.

[0035] In use, the output end of the first drive mechanism 12 is connected to the drive wheel via a coupling, and the first drive mechanism 12 is controlled by an external controller to drive the drive wheel to rotate. By driving the drive wheel to mesh with the gear, the water pipe 13 can be driven to rotate in a circular motion at the upper end of the water pipe 11, thereby enabling horizontal adjustment of the orientation position of the gun head 32.

[0036] For the purpose of adjusting the fire extinguishing position, for example, such as Figure 1 As shown, a worm gear is installed on one side of the outer wall of the connecting pipe 15, and a second drive mechanism 14 is installed on one side of the upper outer wall of the water pipe 13. The second drive mechanism 14 meshes with the worm gear.

[0037] In use, the output end of the second drive mechanism 14 is connected to a worm gear via a coupling, and the second drive mechanism 14 is controlled by an external controller to drive the worm gear to rotate. By driving the worm gear to mesh with the worm wheel, the drain pipe 2 can be driven to rotate circumferentially outside the connecting pipe 15, thereby enabling vertical adjustment of the orientation position of the gun head 32.

[0038] To control the movement trajectory, for example, such as Figure 2 As shown, the outer wall of the second support plate 33 is screwed with a rectangular array of limiting rods 35. The size of the limiting rods 35 is smaller than the size of the movable hole 22, and the limiting rods 35 are movably installed inside the movable hole 22.

[0039] During use, the limiting rod 35 and the movable hole 22 provide guidance and limiting for the extension and retraction of the gun barrel 3, ensuring that the gun barrel 3 will not deviate or shake during the extension and retraction process, thereby improving the stability and reliability of the extension and retraction of the gun barrel 3.

[0040] For sealing purposes, exemplarily, such as Figure 2 As shown, a sealing ring 31 is bonded and fixed to one side of the outer wall of the gun barrel 3. The outer ring of the sealing ring 31 is in contact with the inner wall of the drain pipe 2. A gun head 32 is inserted and installed on the outer wall of one end of the gun barrel 3.

[0041] During use, it can effectively prevent water from leaking in the gap between the cannon barrel 3 and the drain pipe 2, ensuring that all the water can be sprayed out from the cannon head 32, improving the water utilization rate and spraying effect, and the fluid inside the cannon barrel 3 can be sprayed out through the cannon head 32.

[0042] To drive movement, for example, such as Figure 3 As shown, connectors 34 are installed on the upper and lower outer walls of the second support plate 33, and one end of the electric push rod 23 is screwed to the connector 34.

[0043] During use, the connector 34 ensures the stability of the connection between the second support plate 33 and the push rod part of the electric push rod 23, ensuring that the power of the electric push rod 23 can be transmitted to the barrel 3, and enabling precise adjustment of the barrel 3's position.

[0044] When using this utility model, the staff uses external bolts to pass through the fixing holes on both sides of the outer wall of the base 17 to firmly install the device in the designated position, and connects it to the external water source pipe through the flange at one end of the water inlet pipe 16.

[0045] The operator starts the first drive mechanism 12 through an external controller. The output end of the first drive mechanism 12 drives the drive wheel to rotate through a coupling. The drive wheel meshes with a gear on the outer wall of the water pipe 11. The rotation of the gear drives the water pipe 13 to rotate in a circle at the upper end of the water pipe 11, thereby adjusting the position of the gun head 32 in the horizontal direction. The external controller starts the second drive mechanism 14. The output end of the second drive mechanism 14 drives the worm to rotate through a coupling. The worm meshes with a worm wheel on the outer wall of the connecting pipe 15. The rotation of the worm wheel drives the drain pipe 2 to rotate in a circle outside the connecting pipe 15, thereby adjusting the position of the gun head 32 in the vertical direction.

[0046] The operator controls the electric push rod 23 to extend and retract through an external controller. The electric push rod 23 is connected to the second support plate 33 on one side of the outer wall of the gun barrel 3 through the connector 34. The extension and retraction power of the electric push rod 23 is transmitted to the gun barrel 3, causing the gun barrel 3 to extend and retract inside the drain pipe 2. During the extension and retraction of the gun barrel 3, the limiting rod 35 on the outer wall of the second support plate 33 slides in the movable hole 22 inside the first support plate 21, providing guidance and limiting for the extension and retraction of the gun barrel 3.

[0047] External water enters the water supply pipe 11 through the inlet pipe 16, and then passes through the water passage pipe 13, the connecting pipe 15, and the drain pipe 2 to reach the gun barrel 3. When the gun barrel 3 retracts into the drain pipe 2, the conical column 25 at one end of the inner wall support frame 24 of the drain pipe 2 will penetrate into the gun barrel 3. Since the inner diameter of the gun barrel 3 is smaller than the inner diameter of the drain pipe 2, the fluid flows from the wide-section drain pipe 2 to the narrow-section gun barrel 3. According to Bernoulli's principle, the fluid velocity will increase, thereby increasing the fluid's jet distance and jet force.

[0048] It should be noted that this utility model is a fixed remote-controlled fire monitor. All components in this utility model are known to those skilled in the art, and their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
