Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a concealed fire-fighting water monitor. Background Art

[0002] Fire monitors are highly effective devices that use water as an extinguishing medium, capable of extinguishing fires at long distances. They are widely used in a variety of settings. Automatic fire monitors operate by collecting on-site infrared images through a front-end detection system. Manual monitoring or a central controller uses image processing to detect and locate fires within the controlled area. This design facilitates the automatic fire monitor's activation of the corresponding linkage devices and control of the monitor's water spraying operation.

[0003] Chinese utility model patent CN201921627997.8, an angle-adjustable fire water monitor for large spaces, is a common fire water monitor that is generally installed on the ceiling of a factory building. However, in order to increase the spraying range and adjust the angle, this type of fire water monitor usually needs to extend from the ceiling, which has poor aesthetics and is easily affected by external dust and other environmental factors, resulting in a reduced service life. Utility Model Content

[0004] The purpose of the utility model is to provide a concealed fire-fighting water monitor, which can reduce the space occupied by the water monitor.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] In a first aspect, the utility model provides a concealed fire water monitor, comprising an outer water delivery cylinder and an inner water delivery cylinder;

[0007] The first end of the water delivery outer cylinder is provided with a water inlet, the first end of the water delivery inner cylinder extends from the second end of the water delivery outer cylinder to the interior of the water delivery outer cylinder, and the outer wall of the water delivery inner cylinder is slidingly and sealingly connected to the opening of the second end of the water delivery outer cylinder, and the second end of the water delivery inner cylinder is equipped with a water monitor body;

[0008] A piston is installed at the first end of the water delivery inner cylinder, and the outer peripheral side wall of the piston is slidably and sealedly connected to the middle inner side wall of the water delivery outer cylinder; a communication hole is opened on the side wall of the first end of the water delivery inner cylinder;

[0009] The second end of the water delivery outer cylinder is provided with an annular protrusion; the inner diameter of the annular protrusion is larger than the outer diameter of the piston.

[0010] The effect produced by the above arrangement is: when spraying water to extinguish a fire, under the action of the water flow pressure, the piston is pushed downward, and the water delivery inner cylinder is pushed out. At the same time, the inner diameter of the annular protrusion is larger than the outer diameter of the piston, so that the piston and the communicating hole enter the inner cavity of the annular protrusion. There is a water-passing gap between the edge of the piston and the inner side wall of the annular protrusion. At this time, the water flows through the inner cavity of the annular protrusion, bypasses the piston and flows into the communicating hole, thereby entering the water delivery inner cylinder, and is output through the pushed out water delivery inner cylinder for fire fighting. When fire fighting is not needed, the water delivery inner cylinder can be hidden in the water delivery outer cylinder, reducing the occupied space and achieving the effect of being hidden on the top plate.

[0011] The present invention is further configured as follows: a return spring is connected between the piston and the inner side wall of the first end of the water delivery outer cylinder.

[0012] The effect of the above setting is that the reset spring can automatically reset the water delivery outer cylinder and the water delivery inner cylinder after the water flow pressure decreases, so that the piston returns to its original position, blocking the water flow while keeping it hidden for easy use next time.

[0013] The present invention is further configured as follows: a blocking column is fixedly installed on one end of the inner cavity of the annular protrusion close to the water monitor body, and the height of the blocking column is greater than the distance from the edge of the communicating hole to the edge of the piston.

[0014] The effect of the above arrangement is that the height of the blocking column is greater than the distance from the edge of the communicating hole to the edge of the piston, so that when the piston contacts the blocking column, the communicating hole is still located in the inner cavity of the annular protrusion, so that water can still flow into the communicating hole through the inner cavity of the annular protrusion and enter the water delivery inner cylinder.

[0015] The present invention is further configured as follows: a retaining ring is fixedly mounted on the inner wall of the water delivery outer cylinder, and the inner diameter of the retaining ring is smaller than the outer diameter of the piston.

[0016] The effect of the above setting is that the retaining ring can limit the rising position of the piston, preventing the rising position of the piston from exceeding the water inlet of the water delivery outer cylinder, thereby causing water leakage and the water blocking structure to lose its function.

[0017] The utility model is further configured as follows: a water spray head is provided at the end of the water monitor body.

[0018] The effect of the above settings: Setting the sprinkler head is conducive to better spraying the water from the inner drum, adjusting the spraying direction, and improving the spraying effect.

[0019] The present invention is further configured as follows: the outer cover of the water monitor body is provided with a protective box.

[0020] The effect of the above settings is: the protective box is used to protect and hide the water monitor body, reducing the pollution of the water monitor equipment due to environmental factors, thereby extending the service life of the fire water monitor.

[0021] The present invention is further configured as follows: an opening is provided on at least one surface of the protection box, and a sealing film is fixedly installed at the opening of the protection box.

[0022] The effect of the above settings is: the sealing film is used to better encapsulate the water monitor body, and the fire water monitor is completely concealed in the ceiling when not in use, which maintains the aesthetics of the factory and reduces the pollution of the equipment due to environmental factors, thereby extending the service life of the fire water monitor. In addition, the sealing film is easy to be destroyed and will not affect the use of the water monitor.

[0023] The utility model is further configured as follows: an annular cutter is fixedly installed at the water outlet of the water spray head.

[0024] The effect of the above setting is that the protective film can be cut conveniently by the circular cutter.

[0025] The present invention is further configured such that: the blade of the annular cutter forms an oblique angle with the sealing film.

[0026] The effect of the above setting is: when the water spray head is extended, the sealing film will be squeezed outward by the ring knife and deformed. The bevel angle can easily cut the sealing film while avoiding accidental touch caused by some small disturbances that may cause the sealing film to be cut.

[0027] The utility model is further configured as follows: the protection box is filled with dry powder fire extinguishing agent.

[0028] The effect of the above setting is: when the sprinkler head is extended, the sealing film is destroyed and the fire extinguishing agent is sprayed out, which effectively improves the fire extinguishing speed.

[0029] The present invention is further configured as follows: a push plate is installed on the water monitor body.

[0030] The effect of the above setting is: when the water monitor is extended, the push plate can quickly push out the dry powder fire extinguishing agent in the protective box to cover the fire area and increase the fire extinguishing speed.

[0031] The utility model is further configured as follows: a water inlet pipe is provided on one side of the top of the water delivery outer cylinder, and the water inlet end of the water inlet pipe is connected to the water delivery pipe.

[0032] The above settings produce the following effects: the water inlet pipe is used to supply water to the device from a water source.

[0033] In summary, the present invention has the following beneficial effects:

[0034] 1. The utility model completely conceals the fire water monitor in the ceiling when not in operation, thereby maintaining the aesthetics of the factory building and reducing the pollution of the equipment due to environmental factors, thereby extending the service life of the fire water monitor.

[0035] 2. When a fire occurs, the water pressure-driven automatic deployment mechanism can quickly push the water monitor body out of the protective box to achieve rapid response.

[0036] 3. The design of the protective box and annular cutter simplifies the activation and maintenance process of the water monitor, further ensuring the reliability and convenience of the system.

[0037] 4. Overall, the implementation of this solution has improved fire extinguishing efficiency, strengthened automated operations in emergency situations, facilitated daily maintenance, and enhanced the overall safety level of industrial plants. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] The present invention will be further described below with reference to the accompanying drawings in the embodiments of the present invention. Example

[0045] like Figure 1As shown, this embodiment provides a concealed fire water monitor, including a water delivery outer cylinder 2 and a water delivery inner cylinder 6; a water inlet is provided at the first end of the water delivery outer cylinder 2, and the first end of the water delivery inner cylinder 6 passes through the second end of the water delivery outer cylinder 2 to the interior of the water delivery outer cylinder 2, and the outer wall of the water delivery inner cylinder 6 is slidingly and sealedly connected to the opening of the second end of the water delivery outer cylinder 2, and a water monitor body 9 is installed at the second end of the water delivery inner cylinder 6; a piston 5 is installed at the first end of the water delivery inner cylinder 6, and the outer peripheral side wall of the piston 5 is slidingly and sealedly connected to the middle inner side wall of the water delivery outer cylinder 2; a connecting hole 601 is provided on the side wall of the first end of the water delivery inner cylinder 6; an annular protrusion 7 is provided at the second end of the water delivery outer cylinder 2; the inner diameter of the annular protrusion 7 is larger than the outer diameter of the piston 5, so that when the piston 5 is located in the inner cavity of the annular protrusion 7, there is a water-passing gap between the edge of the piston 5 and the inner side wall of the annular protrusion 7.

[0046] Implementation principle: When spraying water to extinguish a fire, under the action of water flow pressure, the piston 5 is pushed downward, and the water delivery inner cylinder 6 is pushed out. At the same time, the piston 5 and the communicating hole 601 enter the inner cavity of the annular protrusion 7. There is a water-passing gap between the edge of the piston 5 and the inner side wall of the annular protrusion 7. At this time, the water flows through the inner cavity of the annular protrusion 7, bypasses the piston 5, and flows into the communicating hole 601, thereby entering the water delivery inner cylinder 6, and is output through the pushed out water delivery inner cylinder 6 for fire fighting. When fire fighting is not needed, the water delivery inner cylinder 6 can be hidden in the water delivery outer cylinder 2 to reduce the occupied space and achieve the effect of being hidden on the top plate.

[0047] The water delivery inner cylinder 6 of this embodiment is preferably equipped with a water monitor body 9 at the bottom to adjust the direction of water flow. The water monitor body 9 can be a conventional fire-fighting water monitor, and its structure will not be described in detail.

[0048] It should be noted that although Figure 1-5 All of them use vertical fire water cannons, but the fire water cannon structure of this application can be set without limiting the angle, such as horizontal setting or inclined setting, and can be freely set according to the actual scene needs. As long as the water pressure at the water inlet can meet the conditions, the structure of this fire water cannon can achieve the hidden function, so the setting position and angle shown in the figure cannot be understood as a limitation on this embodiment. Example

[0049] See also Figures 1 to 3In this embodiment, a hidden fire water monitor is provided, comprising a water delivery outer cylinder 2 and a water delivery inner cylinder 6. The water delivery inner cylinder 6 is slidably mounted inside the water delivery outer cylinder 2. A connecting hole 601 is provided on the top of the water delivery inner cylinder 6. A piston 5 is fixedly mounted on the top of the water delivery inner cylinder 6. The outer wall of the piston 5 fits the inner wall of the water delivery outer cylinder 2. A reset spring 3 is fixedly connected to the top of the piston 5. The top of the reset spring 3 is fixedly connected to the top wall of the water delivery outer cylinder 2. A retaining ring 4 is fixedly mounted on the inner wall of the water delivery outer cylinder 2. The top of the piston 5 is fixedly mounted on the inner wall of the water delivery outer cylinder 2. The wall fits with the retaining ring 4, and an annular protrusion 7 is provided at the bottom of the water delivery outer cylinder 2. A retaining column 8 is fixedly installed at the bottom of the inner cavity of the annular protrusion 7. When spraying water to extinguish a fire, the piston 5 is pushed downward under the action of the water flow, so that the piston 5 contacts the retaining column 8. At this time, the water flows through the inner cavity of the annular protrusion 7 into the communicating hole 601 and enters the water delivery inner cylinder 6. A water monitor body 9 is fixedly installed at the bottom end of the water monitor body 9. A water spray head 901 is provided at the bottom end of the water monitor body 9. The water entering the water delivery inner cylinder 6 is sprayed out through the water spray head 901.

[0050] In this embodiment, preferably, a protective box 10 is fixedly installed at the bottom end of the annular protrusion 7, the water monitor body 9 is arranged in the protective box 10, an opening is provided at the bottom of the protective box 10, and a sealing film 11 is fixedly installed at the opening at the bottom of the protective box 10.

[0051] In this embodiment, preferably, Figure 2 As shown, a circular cutter 12 is fixedly installed at the bottom end of the water spray head 901, and the protective film can be easily cut through the circular cutter 12.

[0052] In this embodiment, preferably, Figure 3 As shown, a water inlet pipe 1 is provided on one side of the top of the water delivery outer cylinder 2 , and the water inlet end of the water inlet pipe 1 is connected to the water delivery pipe 13 .

[0053] Working principle: When installing, Figure 3 As shown, the water inlet pipe 1 is connected to the water delivery pipe 13, and the protection box 10 is installed on the top of the ceiling 14. When a fire occurs, water is injected into the water inlet pipe 1 through the water delivery pipe 13, and the water flows into the water delivery outer cylinder 2. Under the action of water pressure, the piston 5 moves downward, thereby pushing the water delivery inner cylinder 6 to drive the water monitor body 9 to move downward, so that the annular cutter 12 cuts the sealing film 11, allowing the water monitor body 9 to extend from the protection box 10. At the same time, the water monitor body 9 collects on-site infrared images through the front-end detection system in the existing technology, and uses the existing central controller to detect and locate the fire occurring in the control area by means of image processing, and adjusts the angle of the sprinkler head 901 in a targeted manner to spray water to extinguish the fire. Example

[0054] This embodiment provides a concealed fire water monitor, which differs from the concealed fire water monitor described in the second embodiment in that:

[0055] like Figure 4 As shown, the hidden fire water monitor of this embodiment is filled with dry powder fire extinguishing agent in the protective box 10, and a push plate 15 is installed on the water monitor body 9, so that when the water monitor body 9 is extended, the dry powder fire extinguishing agent in the protective box 10 can be quickly pushed out to cover the fire area and increase the fire extinguishing speed.

[0056] Preferably, the push plate is in the shape of a circular disc having the same shape as the inner wall of the protection box, and its edge is smoothed and has a certain amount of slits to facilitate air circulation, so that the push plate 15 can eject the dry powder fire extinguishing agent at one time without encountering too much resistance.

[0057] like Figure 5 As shown, the blade of the annular cutter 12 is arranged outwardly around the central axis of the water delivery inner cylinder 6, forming a 45° angle with the sealing film 11. When the water spray head 901 is extended, the sealing film 11 is squeezed outward by the annular cutter 12, causing it to deform. The 45-degree angle allows for convenient cutting of the sealing film 11 while preventing accidental contact with minor disturbances that could cause the sealing film 11 to be cut.
