Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire protection technology, specifically to a mobile fire monitor. Background Technology
[0002] Fire monitors are important firefighting equipment for long-distance fire suppression. Fire monitors are divided into two main series: fire water monitors (PS) and fire foam monitors (PP). Fire water monitors spray water to extinguish general solid fires from a distance, while fire foam monitors spray air foam to extinguish Class A, B, and C liquid fires from a distance. Fire water monitors consist of a water supply (foam) system, i.e., water (foam) pipelines, an execution system, i.e., the monitor body, nozzles, etc., and a control system. By pressurizing water or foam and spraying it into a column or mist, it can cover fire sources at a distance. It has a large spray flow and long range, and multiple functions, supporting switching between direct (column) and blossom (mist) spray modes, making it suitable for different fire suppression scenarios.
[0003] Although the aforementioned existing technologies can solve the corresponding technical problems, they still have certain drawbacks: when existing mobile fire monitors spray high-pressure water, the nozzle position of the fire monitor will generate a recoil force opposite to the direction of water spray due to the high-speed water jet. Since the bottom of the mobile fire monitor is generally moved by rollers, the recoil force can easily cause the fire monitor to shift position during the spraying process, thus affecting the accuracy of the spray. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a mobile fire monitor with good stability and accurate spraying.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mobile fire monitor, including a water spray pipe and a water inlet pipe fixedly installed at the rear end of the water spray pipe, a fixed frame is movably engaged on the side wall of the water spray pipe, a mobile chassis is movably engaged on the bottom surface of the fixed frame, the mobile chassis includes a placement plate and a moving wheel fixedly installed on the bottom surface of the placement plate, and a fixed column is slidably provided through the placement plate.
[0006] A further improvement is that a support frame is welded to the top of the water spray pipe.
[0007] A further improvement is that the fixing post includes a penetrating post that is slidably disposed on the placement plate and a fixing block with a square groove disposed on the bottom surface of the penetrating post.
[0008] A further improvement is that the top surface of the penetrating column is provided with a pedal, and the upper surface of the pedal is integrally formed with several square grooves.
[0009] A further improvement is that a friction layer is integrally formed on the side wall of the penetrating column.
[0010] A further improvement is that the side wall of the penetrating column is integrally formed with a sliding groove, and a bullet-shaped sliding block is slidably provided on the inner wall of the sliding groove. A thrust spring is provided between one side of the sliding block and the inner wall of the sliding groove.
[0011] A further improvement is that the bottom surface of the penetrating column is also movably engaged with an inclined pressure plate.
[0012] A further improvement is that the lower surface of the pressure plate is integrally formed with several square grooves, and an elastic sheet is provided between the upper surface of the pressure plate and the side wall of the penetrating column.
[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When using this utility model, if spraying is required, the fixed column can be stepped down with both feet to move the fixed column downward and press its bottom against the floor. At this time, the friction and downward pressure of the fixed column can prevent the moving chassis from moving during spraying, thereby improving the stability during spraying and preventing the problem of decreased accuracy caused by the movement of the moving chassis due to the recoil during spraying.

[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0019] See Figs. 1-3As shown, the technical solution adopted in this specific embodiment is: a mobile fire monitor, including a water spray pipe 1 and a water inlet pipe 2 fixedly installed at the rear end of the water spray pipe 1. A fixing frame 4 is movably engaged on the side wall of the water spray pipe 1, and a mobile chassis 5 is movably engaged on the bottom surface of the fixing frame 4. The mobile chassis 5 includes a placement plate 51 and moving wheels 52 fixedly installed on the bottom surface of the placement plate 51. A fixing post 53 is slidably provided through the placement plate 51. The fixing post 53 includes a penetrating post 21 slidably installed through the placement plate 51 and a fixing block 25 with a square groove installed on the bottom surface of the penetrating post 21. In use, the moving wheels 52 of the mobile chassis 5 drive the entire fire monitor to the required position, and the fixing frame 4 movably engages the entire fire monitor on the placement plate 51. At this time, it can be twisted up and down. The spray pipe 1 can adjust the vertical spray angle of the fire monitor, and the left and right spray angle of the fire monitor can be adjusted by twisting the spray pipe 1 left and right. Connect the high-pressure water pipe to the inlet pipe 2 so that the high-pressure water flow is forced into the spray pipe 1 for spraying. When spraying, you can step down on the fixed column 53 with both feet to move the penetrating column 21 of the fixed column 53 downward and press the fixed block 25 at the bottom of the fixed column 53 against the floor. The lower surface of the fixed block 25 has multiple square grooves integrally formed. At this time, the downward pressure of the penetrating column 21 of the fixed column 53 and the friction between the fixed block 25 and the ground can make the mobile chassis resist the recoil of the spray during spraying, so that it will not move and thus improve the stability of spraying. This prevents the problem of decreased accuracy caused by the movement of the mobile chassis 5 due to the recoil of the spray.
[0020] The top of the water spray pipe 1 is welded with a support frame 3, which makes it easier to control the angle of the water spray pipe 1 through the support frame 3, and can be held during spraying to improve the control effect of the water spray pipe 1.
[0021] The top surface of the penetrating column 21 is provided with a pedal 27. The upper surface of the pedal 27 is integrally formed with several square grooves, which helps to prevent slipping when the foot steps on it and makes the force transmission more direct.
[0022] The friction layer 22 is integrally formed on the side wall of the penetrating column 21, which helps to increase the friction between the side wall of the penetrating column 21 and the placement plate 51, thereby preventing the penetrating column 21 from falling during normal movement.
[0023] The side wall of the penetrating column 21 is integrally formed with a sliding groove 23. The inner wall of the sliding groove 23 is slidably provided with a bullet-shaped sliding block 24. A thrust spring is provided between one side of the sliding block 24 and the inner wall of the sliding groove 23. This facilitates the sliding block 24 to be pushed out of the sliding groove 23 by the thrust spring when the penetrating column 21 moves to a sufficiently low height, and makes the sliding block 24 stuck on the bottom surface of the placement plate 51, preventing the penetrating column 21 from moving upward and affecting the fixing effect.
[0024] The bottom surface of the penetrating column 21 is also movably engaged with an inclined pressure plate 26, which is beneficial for the pressure plate 26 to be squeezed open after the penetrating column 21 moves down to a certain height, thereby increasing the contact area with the ground and generating greater friction, thereby improving the fixing effect and preventing slippage.
[0025] The lower surface of the pressure plate 26 is integrally formed with several square grooves. An elastic sheet is provided between the upper surface of the pressure plate 26 and the side wall of the penetrating column 21, which helps to further increase the friction coefficient between the pressure plate 26 and the ground, thereby increasing the friction force and making the fixation more secure. The elasticity of the elastic sheet further improves the friction fixation effect.
[0026] The working principle of this utility model is as follows: When in use, the moving wheels 52 of the movable chassis 5 drive the entire fire monitor to the required position. The fixing frame 4 locks the entire fire monitor onto the placement plate 51. At this time, twisting the water spray pipe 1 up and down can adjust the up and down spray angle of the fire monitor, and twisting the water spray pipe 1 left and right can adjust the left and right spray angle of the fire monitor. Connecting the high-pressure water pipe to the inlet pipe 2 allows the high-pressure water to be forced into the water spray pipe 1 for spraying. When spraying, the fixed column 53 can be stepped down with both feet, which will cause the penetrating column 21 of the fixed column 53 to move downward and press the fixing block 25 at its bottom against the floor. The lower surface of the fixing block 25 has multiple square grooves integrally formed. At this time, the downward pressure of the penetrating column 21 of the fixed column 53, combined with the friction between the fixing block 25 and the ground, allows the movable chassis to resist the recoil caused by the spray during spraying, preventing movement and thus improving the stability during spraying. This prevents the accuracy problem caused by the movement of the movable chassis 5 due to the recoil during spraying.
