Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire monitor technology, specifically a mobile fire monitor device. Background Technology
[0002] Fire monitors are important firefighting equipment for long-distance fire suppression. They are divided into two main series: water monitors (PS) and foam monitors (PP). Water monitors spray water to extinguish general solid fires from a distance, while foam monitors spray air foam to extinguish Class A, B, and C liquid fires from a distance. The equipment description states that water monitors use water as a medium to extinguish fires from a distance.
[0003] Chinese utility model patent application number 202323044005.8 provides a mobile fire extinguishing and fire monitor device for fire protection engineering. By placing the fixed base on the installation position on the fire truck, and then rotating the handwheel to rotate the clamping screw, the clamping plate is driven closer to the installation position under the action of the threaded sleeve. Therefore, the installation position can be clamped by clamping the soft pad to achieve convenient fixation of the fixed base, thereby avoiding the inconvenience caused by turning the strong spring, and thus providing convenience for the user.
[0004] However, during the use of the above equipment, it was found that the bracket used for the fire monitor in the equipment is fixedly installed on the fixed base. This means that after the fixed base is fixedly installed in the installation position, the horizontal rotation range may have a certain limit, making it impossible to achieve all-round coverage without blind spots. In some large-scale fire scenarios, there are multiple scattered fire points, which are difficult to completely cover. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a mobile fire monitor device, which solves the problem mentioned in the background technology that when the fixed base is fixedly installed in the installation position, the horizontal rotation range may have certain limits, making it impossible to achieve all-round coverage without blind spots.

[0008] Preferably, the bottom of the fixing frame is provided with a fixing component, which includes a bidirectional threaded rod. The bidirectional threaded rod is fixedly connected to a worm gear and is rotatably mounted on the bottom of the fixing frame. Slide rods are arranged parallel to each other on both sides of the bidirectional threaded rod.
[0009] Preferably, the slide rod is fixedly installed at the bottom of the fixed frame, and movable frames are slidably installed on both ends of the slide rod.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example 1:
[0022] Please see Figures 1-4A mobile fire monitor device includes a fixed frame 1, a rotating shaft 4 rotatably mounted at the top center of the fixed frame 1, a support frame 6 mounted on the top fixed rod of the rotating shaft 4, a fire monitor assembly 7 rotatably mounted on the support frame 6, a limiting plate 41 fixedly mounted at the center of the rotating shaft 4, a limiting hole 42 formed in a circular array on the limiting plate 41, a limiting assembly 5 provided on the fixed frame 1, the limiting assembly 5 including a limiting frame 51, the limiting frame 51 having a first slot 511 and a second slot 512, the length of the first slot 511 being greater than the length of the second slot 512. The bottoms of slot 1 511 and slot 2 512 are connected. A limiting plate 55 is slidably installed in the inner cavity of the limiting frame 51. A limiting rod 52 is fixedly installed on the top of the limiting plate 55. The limiting rod 52 passes through the top of the limiting frame 51 and is adapted to the limiting hole 42. The bottom of the limiting plate 55 is connected to the bottom of the limiting frame 51 through a spring 54. A rotating plate 56 is rotatably installed on the limiting rod 52. A lever 53 is fixedly installed on one side of the rotating plate 56. The diameter of the lever 53 is adapted to the width of slot 1 511 and slot 2 512.
[0023] Specifically, under normal conditions, lever 53 is at the top of slot one 511. At this time, limit rod 52 is inserted into limit hole 42 to restrict limit plate 41, and spring 54 is in normal state. When it is necessary to adjust the horizontal angle of fire monitor assembly 7, the operator moves lever 53 along slot one 511. Since lever 53 is fixed on rotating plate 56, and rotating plate 56 is rotatably mounted on limit rod 52, the movement of lever 53 will drive rotating plate 56 to move, causing limit plate 55 to squeeze spring 54. When lever 53 moves to the bottom of slot one 511, lever 53 is rotated to enter slot two 512. The operator releases lever 53, causing lever 53 to move to the top of slot two 512 under the action of spring 54, thereby causing limit rod 52 to disengage from limit hole 42, making it easier for the operator to rotate fire monitor assembly 7 along rotating shaft 4 to achieve a wider range of aiming and spraying.
[0024] When it is necessary to fix the angle of the fire monitor assembly 7, the operator moves the lever 53 along the slot 2 512, so that the lever 53 drives the limiting plate 55 to the bottom of the slot 2 512. Then, the lever 53 is rotated to enter the slot 1 511, so that the lever 53 and the limiting plate 55 move to the top of the slot 1 511 under the action of the spring 54, thereby causing the limiting rod 52 to enter the limiting hole 42, thereby restricting the rotation of the rotating shaft 4, and thus fixing the horizontal angle of the fire monitor assembly 7.
[0025] Example 2:
[0026] To improve equipment stability, please refer to Figures 1-4Based on embodiment 1, a drive assembly 2 is provided at one end of the fixed frame 1. The drive assembly 2 includes a drive box 21. A worm gear 23 is rotatably installed inside the drive box 21. A worm wheel 22 is meshed with one side of the worm gear 23. One end of the worm gear 23 is fixedly connected to a turntable 24. A handle is provided on the turntable 24.
[0027] The bottom of the fixed frame 1 is provided with a fixed component 3, which includes a bidirectional threaded rod 31. The bidirectional threaded rod 31 is fixedly connected to the worm gear 22. The bidirectional threaded rod 31 is rotatably installed at the bottom of the fixed frame 1. Slide rods 32 are arranged parallel to each other on both sides of the bidirectional threaded rod 31.
[0028] The slide bar 32 is fixedly installed at the bottom of the fixed frame 1. A movable frame 33 is slidably installed on both ends of the slide bar 32. The movable frame 33 is screwed to the bidirectional threaded rod 31. A clamping plate 34 is fixedly installed at the bottom of the movable frame 33.
[0029] A support plate 11 is fixedly installed at the bottom center of the fixed frame 1. The bidirectional threaded rod 31 and the slide rod 32 both pass through the support plate 11. Anti-slip pads 8 are provided at the bottom of the support plate 11 and on the inner side of the clamping plate 34.
[0030] Specifically, rotating the handle on the turntable 24 in the drive assembly 2 drives the worm gear 23 to rotate. Since the worm gear 23 is meshed with the worm wheel 22, its rotation causes the worm wheel 22 to rotate as well. Because the worm wheel 22 is fixedly connected to the bidirectional threaded rod 31 in the fixing assembly 3, the bidirectional threaded rod 31 also rotates. When the bidirectional threaded rod 31 rotates, the movable frame 33, which is helically connected to it on both sides, slides on the slide bar 32, causing the clamping plate 34 at the bottom of the movable frame 33 to move closer to or further away from the fixed seat. When it is necessary to fix the equipment, rotating the handle moves the clamping plate 34 closer to and clamps the fixed seat. The anti-slip pad 8 on the inner side of the clamping plate 34 increases friction, thus firmly fixing the equipment to the fixed seat and improving its stability.
[0031] The support plate 11 at the bottom center of the fixed frame 1 not only provides a support point for the bidirectional threaded rod 31 and the slide rod 32, but also the anti-slip pad 8 at its bottom increases the friction between the equipment and the fixed seat. While the clamping plate 34 clamps the fixed seat, the anti-slip pad 8 at the bottom of the support plate 11 also makes close contact with the fixed seat, further enhancing the connection stability between the equipment and the fixed seat and preventing the equipment from shifting or shaking during operation;
[0032] Because the worm gear 22 and worm 23 transmission has self-locking properties, when adjusting the position of the clamping plate 34, once the operator has adjusted the clamping plate 34 to the appropriate position, even if there is slight vibration or interference from the outside, the worm gear 22 will not easily reverse, thereby ensuring the stability of the position of the clamping plate 34, achieving precise control of the position of the clamping plate 34, and ensuring that the equipment can be stably fixed on the fixed base.
[0033] Working principle: Move the mobile fire monitor to the desired location, turn the handle on the turntable 24 in the drive assembly 2 to rotate the worm gear 23, which in turn causes the worm wheel 22 to rotate the double-threaded rod 31. When the double-threaded rod 31 rotates, the movable frame 33, which is helically connected to the double-threaded rod 31 on both sides, slides on the slide bar 32, bringing the clamping plate 34 at the bottom of the movable frame 33 closer to the fixed seat. After the clamping plate 34 is close to the fixed seat, continue to turn the handle to clamp the clamping plate 34 to the fixed seat. At this time, the anti-slip pad 8 on the inner side of the clamping plate 34 increases the friction, firmly fixing the equipment to the fixed seat.
[0034] When the fire monitor assembly 7 needs to be rotated, the operator moves the lever 53 along slot 1 511, causing the rotating plate 56 to move and the limiting plate 55 to compress the spring 54. When the lever 53 moves to the bottom of slot 1 511, the operator rotates the lever 53 to enter slot 2 512. Then the operator releases the lever 53, and the lever 53 moves to the top of slot 2 512 under the action of the spring 54, thereby causing the limiting rod 52 to disengage from the limiting hole 42. At this time, the fire monitor assembly 7 can be rotated along the rotating shaft 4, which facilitates a wider range of aiming and spraying.
[0035] When the fire monitor assembly 7 is not in use or not fixed, the operator moves the lever 53 along slot two 512, causing the limiting plate 55 to move to the bottom of slot two 512. Then, the lever 53 is rotated to enter slot one 511. Releasing the lever 53 allows the lever 53 and the limiting plate 55 to move to the top of slot one 511 under the action of the spring 54, thereby causing the limiting rod 52 to enter the limiting hole 42, thus restricting the rotation of the rotating shaft 4 and fixing the horizontal angle of the fire monitor assembly 7.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
