Description

Technical Field

[0001] This utility model relates to the field of fire protection structure technology, and in particular to a fire monitor head structure. Background Technology

[0002] A fire monitor is a fire-fighting device that sprays water to extinguish general solid fires from a distance. Its main function is to extinguish fires from a distance. Using water as the medium, it is suitable for locations such as petrochemical plants, tank farms, aircraft hangars, warehouses, and ports, and is an ideal vehicle-mounted device for fire trucks.

[0003] Chinese utility model patent CN211835970U discloses a fire monitor head with good jet effect, including a monitor head body, a water outlet baffle, and a connecting rod. A flow rectifier is fixedly installed in the monitor head body, with the upper end of the monitor head body as the water outlet. A water outlet gap is formed between the water outlet baffle and the water outlet. The connecting rod passes through the water outlet baffle and the flow rectifier sequentially from top to bottom. A positioning block is provided around the position between the water outlet baffle and the flow rectifier on the connecting rod. The positioning block has a first positioning surface and a second positioning surface. An embedding block located below the positioning block is also provided around the connecting rod. An embedding through groove is opened in the flow rectifier that fits into the embedding block. The upper end of the connecting rod is fixed above the water outlet baffle, and the lower end of the connecting rod is fixed below the flow rectifier.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the distance between the water outlet baffle and the water outlet is inconvenient to adjust, which is not conducive to firefighters adjusting the water output of the fire monitor as needed to achieve the purpose of rapid fire extinguishing. Utility Model Content

[0005] To solve the above problems, this utility model provides a fire monitor head structure.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a fire monitor head structure, including a monitor head body, a rectifier column disposed in the monitor head body, and a water outlet baffle disposed at one end of the rectifier column and located in the water outlet near the monitor head body. A central rod is fixed at one end of the rectifier column near the water outlet baffle. The central rod passes through the water outlet baffle and is clearance-fitted. A spring sleeved on the central rod is fixed between the water outlet baffle and the rectifier column. A fixing component connected to the central rod and used to fix the water outlet baffle is disposed on the side of the water outlet baffle away from the rectifier column.

[0007] By adopting the above technical solution, the fixing component connects the water outlet baffle to the center rod to fix the water outlet baffle. By loosening the fixing component, the staff can press the water outlet baffle towards the side closer to the rectifier column, so that the spring is compressed. This allows the staff to adjust the distance between the bottom of the water outlet baffle and the water outlet of the nozzle body as needed, thereby adjusting the water output of the fire monitor and facilitating the rapid extinguishing of fires.

[0008] Furthermore, the fixing assembly includes a clamping plate sleeved on the central rod and threadedly connected to the central rod, and a rotating rod fixed to the side of the clamping plate away from the water outlet baffle. The rotating rod has two parts and is symmetrically arranged about the central rod.

[0009] By adopting the above technical solution, the staff can rotate the pressure plate by rotating the rods on both sides of the central rod, so that the pressure plate pushes the water outlet block, and the spring is gradually compressed, thereby adjusting the distance between the bottom of the water outlet block and the water outlet of the nozzle body, and thus adjusting the water output of the fire nozzle.

[0010] Furthermore, the rotating rod is S-shaped, and the distance between the upper ends of the two rotating rods is less than the distance between the lower ends of the two rotating rods.

[0011] By adopting the above technical solution, the probability of the operator being unable to rotate the pressure plate by the two rotating rods is reduced due to the close distance between the two rotating rods and the center rod.

[0012] Furthermore, a rubber sleeve is fixedly fitted onto the upper end of each rotating rod.

[0013] By adopting the above technical solution, the rubber sleeve increases the friction between the worker's hand and the upper end of the rotating rod, reducing the probability of slippage when the worker rotates the pressure plate through the two rotating rods.

[0014] Furthermore, an installation plate is provided between the water outlet baffle and the pressure plate. The central rod passes through the installation plate and is clearance-fitted. Cylindrical balls are provided on both the water outlet baffle and the pressure plate. Multiple balls are provided and evenly distributed about the axis of the central rod. The top of the water outlet baffle is provided with a lower groove that mates with the balls. The bottom of the installation plate is provided with an upper groove that mates with the balls. The top of the balls abuts against the bottom of the pressure plate. A lower screw that is clearance-fitted to the installation plate passes through the installation plate. The lower end of the lower screw is threaded to the top of the water outlet baffle.

[0015] By adopting the above technical solution, the ball bearings enable a rolling connection between the water outlet baffle and the pressure plate, reducing the friction between the water outlet baffle and the pressure plate.

[0016] Furthermore, the side of the water outlet baffle away from the rectifier column is integrally formed with an annular plate body surrounding the edge of the water outlet baffle.

[0017] By adopting the above technical solution, the annular plate effectively intercepts the water from the fire monitor, reducing the probability of water splashing onto the fixed components and affecting subsequent use.

[0018] Furthermore, a sleeve is fixed to one end of the rectifier column near the outlet baffle. The sleeve is fitted onto the outside of the spring. An annular groove is provided at the bottom of the outlet baffle for inserting and engaging the sleeve. The depth of the annular groove is greater than or equal to the length of the sleeve.

[0019] By adopting the above technical solution, the sleeve effectively blocks the water flow, preventing water from leaking out from the gap between the central rod and the outlet baffle and affecting the water pressure, thus ensuring the outlet pressure and facilitating rapid fire extinguishing.

[0020] Furthermore, a connecting plate is fixed to the lower end of the rotating rod, and an upper screw that fits into the connecting plate is provided through the connecting plate. The lower end of the upper screw is threadedly connected to the top of the clamping plate.

[0021] By adopting the above technical solution, the stability of the rotating rod during use is ensured.

[0022] Furthermore, a base plate is fixed to the bottom of the rectifier column, and multiple connecting rods are evenly fixed to the side wall of the base plate. The ends of the multiple base plates away from the base plate are all fixed to the inner wall of the gun head body near the lower end of the gun head body.

[0023] By adopting the above technical solution, the base plate and connecting rod are designed to fix the rectifier column inside the gun head.

[0024] Furthermore, a hemisphere is fixed to the bottom of the base plate.

[0025] By adopting the above technical solution, the hemisphere plays a good guiding and dispersing role for water flow, reducing the probability that the water flow pressure will be affected by the obstruction of the flat surface.

[0026] In summary, this utility model has the following beneficial effects:

[0027] 1. In this application, the fixing component connects the water outlet baffle to the center rod to fix the water outlet baffle. By loosening the fixing component, the operator can press the water outlet baffle toward the side closer to the rectifier column, so that the spring is compressed. This allows the operator to adjust the distance between the bottom of the water outlet baffle and the water outlet of the nozzle body as needed, thereby adjusting the water output of the fire monitor, which is conducive to quickly extinguishing fires.

[0028] 2. In this application, the operator can rotate the pressure plate by rotating the rods on both sides of the central rod, so that the pressure plate pushes the water outlet block, and the spring is gradually compressed, thereby adjusting the distance between the bottom of the water outlet block and the water outlet of the nozzle body, and thus adjusting the water output of the fire nozzle.

[0034] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0035] like Figure 1-4As shown in the figure, this application discloses a fire monitor head structure, including a monitor head body 1, a rectifier column 2 disposed in the monitor head body 1 (specifically: a base plate 3 is fixed to the bottom of the rectifier column 2, a plurality of connecting rods 31 are uniformly fixed to the side wall of the base plate 3, and the ends of the base plates 3 away from the base plate 3 are fixed to the inner wall of the monitor head body 1 near the lower end of the monitor head body 1), and a water outlet baffle 4 disposed at one end of the rectifier column 2 and located in the water outlet near the monitor head body 1. A central rod 41 is fixed to the end of the rectifier column 2 near the water outlet baffle 4. The central rod 41 passes through the water outlet baffle 4 and is clearance-fitted. A spring 411 is fixed between the water outlet baffle 4 and the rectifier column 2 and sleeved on the central rod 41. A fixing component 5 is disposed on the side of the water outlet baffle 4 away from the rectifier column 2, which is connected to the central rod 41 and used to fix the water outlet baffle 4.

[0036] The fixing component 5 connects the water outlet baffle 4 to the center rod 41 to fix the water outlet baffle 4. By loosening the fixing component 5, the staff can press the water outlet baffle 4 toward the side closer to the rectifier column 2, so that the spring 411 is compressed. This allows the staff to adjust the distance between the bottom of the water outlet baffle 4 and the water outlet of the nozzle body 1 as needed, so as to adjust the water output of the fire nozzle, which is conducive to quickly extinguishing the fire.

[0037] The fixing component 5 includes a clamping plate 51 sleeved on the central rod 41 and threadedly connected to the central rod 41, and a rotating rod 52 fixed to the side of the clamping plate 51 away from the water outlet block 4. There are two rotating rods 52, which are symmetrically arranged about the central rod 41.

[0038] The operator can rotate the pressure plate 51 by rotating the rods 52 on both sides of the central rod 41, so that the pressure plate 51 pushes the water outlet block 4, and the spring 411 is gradually compressed, thereby adjusting the distance between the bottom of the water outlet block 4 and the water outlet of the nozzle body 1, and thus adjusting the water output of the fire nozzle.

[0039] To reduce the probability that the close proximity of the two rotating rods 52 to the center rod 41 would affect the operator's ability to rotate the pressure plate 51, the rotating rods 52 are S-shaped, and the distance between the upper ends of the two rotating rods 52 is smaller than the distance between their lower ends. To further reduce the probability of slippage during rotation, each rotating rod 52 is fixedly fitted with a rubber sleeve 521.

[0040] An mounting plate 6 is provided between the water outlet baffle 4 and the pressure plate 51. The central rod 41 passes through the mounting plate 6 and is clearance-fitted. Both the water outlet baffle 4 and the pressure plate 51 are provided with cylindrical ball bearings 7. Multiple ball bearings 7 are evenly distributed about the axis of the central rod 41. The top of the water outlet baffle 4 has a lower groove 42 that mates with the ball bearings 7. The bottom of the mounting plate 6 has an upper groove 61 that mates with the ball bearings 7. The top of the ball bearings 7 abuts against the bottom of the pressure plate 51. A lower screw 62, which is clearance-fitted to the mounting plate 6, passes through the mounting plate 6. The lower end of the lower screw 62 is threaded to the top of the water outlet baffle 4. The ball bearings 7 allow for a rolling connection between the water outlet baffle 4 and the pressure plate 51, reducing the friction between them.

[0041] The side of the water outlet baffle 4 furthest from the rectifier column 2 is integrally formed with an annular plate 43 surrounding the edge of the water outlet baffle 4. The annular plate 43 effectively intercepts the water from the fire monitor, reducing the probability of water splashing onto the fixed component 5 and affecting subsequent use.

[0042] A sleeve 21 is fixed to one end of the rectifier column 2 near the water outlet baffle 4. The sleeve 21 is fitted onto the outside of the spring 411. The bottom of the water outlet baffle 4 is provided with an annular groove 44 for inserting and engaging the sleeve 21. The depth of the annular groove 44 is greater than or equal to the length of the sleeve 21. The sleeve 21 effectively blocks the water flow, preventing water from leaking out from the gap between the central rod 41 and the water outlet baffle 4 and affecting the water pressure, thus ensuring the water pressure and facilitating rapid fire extinguishing.

[0043] To ensure the stability of the rotating rod 52 during use, a connecting plate 8 is fixed to the lower end of the rotating rod 52. An upper screw 81 is provided through the connecting plate 8 to reduce the fit with the connecting plate 8. The lower end of the upper screw 81 is threaded to the top of the clamping plate 51.

[0044] The bottom of the base plate 3 is fixed with a hemisphere 32, which plays a good guiding and dispersing role for the water flow, reducing the probability that the water flow pressure will be affected by the flat surface.

[0045] In this embodiment, the working principle of the fire monitor head structure is as follows: the operator can rotate the pressure plate 51 by rotating the rotating rods 52 on both sides of the central rod 41, so that the pressure plate 51 pushes the water outlet block 4, and the spring 411 is gradually compressed, thereby adjusting the distance between the bottom of the water outlet block 4 and the water outlet of the monitor head 1, and thus adjusting the water output of the fire monitor head.

[0046] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
