Description

Technical Field

[0001] This invention relates to the field of chemical fire protection technology, and in particular to a mobile water cannon device for fire-fighting dikes. Background Technology

[0002] Fire dikes are typically set up around petrochemical storage tank areas, with water cannons installed on them to deal with fires. This setup eliminates the need for firefighters to get close to the fire, thus improving the safety of firefighting and rescue operations.

[0003] Currently, the structure of water cannons installed on fire dikes has shortcomings: 1. A row of fire cannons is usually fixed on the fire dike and does not have the function of fixed-point support. That is to say, when the local disaster is large, the range of water cannons in distant positions cannot cover the area; 2. There are some mobile water cannons on the market, but these mobile water cannons are located on the fire dike at a high altitude, making maintenance inconvenient. Especially during emergency fire fighting, water cannons that have been working under high intensity for a long time are prone to failure. At this time, manual operation with equipment at height is not only labor-intensive and inconvenient for maintenance, but also extremely prone to safety accidents; 3. The number of mobile water cannons currently on the market is fixed after installation and cannot be increased as needed.

[0004] Therefore, the present invention provides a mobile water cannon device for fire-fighting dikes. Summary of the Invention

[0005] The purpose of this invention is to provide a mobile water cannon device for fire prevention dikes in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A mobile water cannon device for fire prevention dikes includes a water cannon body and a guide rail. A connecting pile is fixedly installed on one side of the guide rail. There are several water cannon bodies. A sliding seat is installed at the bottom of the water cannon body. Guide blocks that do not slide and cooperate with the sliding seat are installed on the upper and lower sides of the guide rail. A pivot rail is installed on the guide rail. The pivot rail is rotatably connected to the guide rail and the guide blocks are also installed on its upper and lower sides. A control mechanism for controlling the rotation of the pivot rail is installed on the guide rail. A sliding drive mechanism that cooperates with the guide blocks is installed on the sliding seat.

[0008] As a further description of the above technical solution:

[0009] The two ends of the hub rail are fixedly connected to the bearing shafts that are rotatably connected to the guide rail. The control mechanism includes a control motor and a transmission gear fixedly sleeved on the bearing shaft. The control motor is fixedly installed at one end of the guide rail and its output end is fixedly connected to a drive gear that meshes with the transmission gear.

[0010] As a further description of the above technical solution:

[0011] The guide rail has a motor slot opposite to one end of the hub rail, and the control motor is fixedly installed in the motor slot.

[0012] As a further description of the above technical solution:

[0013] The sliding drive mechanism includes two drive wheels and a transmission assembly for controlling the synchronous rotation of the two drive wheels. The two drive wheels are respectively located on one side of the slide and near both ends, and the outer peripheral wall of the drive wheel abuts against the guide rail.

[0014] As a further description of the above technical solution:

[0015] The outer peripheral wall of the transmission wheel is fixedly fitted with a rubber sleeve, and a resistance-increasing strip arranged along the length direction is fixedly provided on one side of the guide block.

[0016] As a further description of the above technical solution:

[0017] The transmission assembly includes a transmission motor, a transmission shaft, and a driven bevel gear. A wheel axle that is rotatably connected to the slide is fixedly installed in the middle of the transmission wheel. One end of the wheel axle is fixedly connected to the driven bevel gear. The transmission shaft is rotatably connected to one side of the slide and a driving bevel gear that meshes with the driven bevel gear is fixedly sleeved on it. The transmission motor is fixedly installed on one side of the slide and its output end is fixedly connected to the transmission shaft.

[0018] As a further description of the above technical solution:

[0019] The water cannon body and the slide are detachably connected. A carrier plate located below the hub rail is suspended on one side of the guide rail by two rods. The carrier plate is slidably installed up and down. A support beam is fixedly connected between the two rods. A lead screw is rotatably connected to the support beam. The lead screw and the carrier plate are screwed together.

[0020] As a further description of the above technical solution:

[0021] A drive motor is fixedly connected to the bottom of the support beam, and the output end of the drive motor is fixedly connected to the bottom of the lead screw.

The sliding seat slides in conjunction with both the guide rail and the pivot rail. The water cannon body can freely switch between above and below the guide rail via the pivot rail. This arrangement divides the water cannon body into an on-duty state and an off-duty state. The off-duty state water cannon body is located on the outside of the fire dike and its height is reduced, which has the advantage of facilitating regular maintenance by maintenance personnel along the way.

[0028] 2. In this invention, by setting up a hub rail and a slide, it is convenient to quickly transport each water cannon body in the off-duty state to the on-duty state, and it also has the advantage of providing on-demand fixed-point support.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1

[0041] Please see Figure 1-6 A mobile water cannon device for fire dikes includes a water cannon body 1 and a guide rail 2. A connecting pile 103 is fixedly installed on one side of the guide rail 2, and the guide rail 2 is installed on the outer wall of the fire dike through the connecting pile 103. There are several water cannon bodies 1. A sliding seat 3 is provided at the bottom of the water cannon body 1. Guide blocks 4 are provided on the upper and lower sides of the guide rail 2, which do not slide and cooperate with the sliding seat 3 at the same time. When the water cannon body 1 is connected to the top guide block 4, the water cannon body 1 is in the working state. A water pipe connector 12 is provided at the bottom of the water cannon body 1. The function of the water pipe connector 12 is to connect to the external water supply hose and play the role of water supply transfer to the water cannon body 1. The water cannon body 1 sprays water to extinguish fire through the spray gun on it. When the water cannon body 1 is connected to the bottom guide block 4, it is in the off-duty ready state. The water cannon body 1 moves its position through the cooperation of the sliding seat 3 and the guide block 4. This configuration can have the function of fixed-point reinforcement fire extinguishing.

[0042] A pivot rail 5 is installed on the guide rail 2. The pivot rail 5 is rotatably connected to the guide rail 2, and guide blocks 4 are also installed on its upper and lower sides. The pivot rail 5 has the function of guiding the water cannon body 1 in the on-duty and off-duty states. The guide rail 2 is equipped with a control mechanism 6 for controlling the rotation of the pivot rail 5. When the water cannon body 1 is located on the pivot rail 5, the rotation of the pivot rail 5 will drive the water cannon body 1 to rotate. When rotated 180 degrees, the water cannon body 1 realizes the switching between the on-duty and off-duty states. The slide 3 is equipped with a sliding drive mechanism 7 that cooperates with the guide blocks 4. That is to say, the slide 3 has a walking function and can move along the guide blocks 4. This configuration makes it convenient to control the number of water cannon bodies 1 in the off-duty state to be greater than the number of water cannon bodies in the on-duty state. The height of the water cannon bodies 1 in the off-duty state is reduced, which facilitates maintenance. Moreover, when needed, the water cannon bodies 1 in the off-duty state can be quickly and precisely reinforced through the pivot rail 5.

[0043] Specifically, the two ends of the pivot rail 5 are fixedly connected to the bearing shaft 51 which is rotatably connected to the guide rail 2. The control mechanism 6 includes a control motor 61 and a transmission gear 62 fixedly sleeved on the bearing shaft 51. The control motor 61 is fixedly installed at one end of the guide rail 2 and its output end is fixedly connected to a drive gear 611 that meshes with the transmission gear 62.

[0044] The guide rail 2 has a motor slot 21 that is opposite to one end of the hub rail 5. The control motor 61 is fixedly installed in the motor slot 21, which can reduce the gap between the hub rail 5 and one end of the guide rail 2 and eliminate the risk of interference.

[0045] The sliding drive mechanism 7 includes two drive wheels 71 and a transmission assembly 72 for controlling the synchronous rotation of the two drive wheels 71. The two drive wheels 71 are respectively located on one side of the slide block 3 and near both ends. The outer peripheral wall of the drive wheel 71 abuts against the guide rail 2. When the two drive wheels 71 rotate, they use friction to drive the slide block 3 to slide relative to the guide block 4. Specifically, the outer peripheral wall of the drive wheel 71 is fixedly fitted with a rubber sleeve 711. A resistance-increasing strip 41 arranged along the length direction is fixedly provided on one side of the guide block 4. The arrangement of the two drive wheels 71 makes it convenient for the slide block 3 to cross the gap between the pivot rail 5 and the guide rail 2.

[0046] The aforementioned transmission assembly 72 includes a transmission motor 721, a transmission shaft 722, and a driven bevel gear 723. A wheel axle 712 rotatably connected to the slide 3 is fixedly installed in the middle of the transmission wheel 71. A seat plate connected to the wheel axle 712 can be welded to one side of the slide 3. One end of the wheel axle 712 is fixedly connected to the driven bevel gear 723. The transmission shaft 722 is rotatably connected to one side of the slide 3, and a driving bevel gear 7221 that meshes with the driven bevel gear 723 is fixedly sleeved on it. A seat plate connected to the transmission shaft 722 can be welded to one side of the slide 3. The transmission motor 721 is fixedly installed on one side of the slide 3, and its output end is fixedly connected to the transmission shaft 722.

[0047] Example 2

[0048] Please see Figure 7 The difference from Embodiment 1 is that the water cannon body 1 and the slide 3 are detachably connected. Specifically, the bottom of the water cannon body 1 is provided with a connecting flange 11 that is bolted to the slide 3. In other words, the water cannon body 1 can be disassembled. A carrier plate 9 located below the hub rail 5 is suspended on one side of the guide rail 2 by two hangers 8. The carrier plate 9 supports the water cannon body 1. The carrier plate 9 is set to slide up and down. Specifically, the carrier plate 9 and the two hangers 8 slide together. The water cannon body 1 is placed upside down on the carrier plate 9. Controlling the height of the carrier plate 9 to lower the height can drive the water cannon body 1 to lower the height, which is convenient for replacing the faulty water cannon body 1. A support beam 81 is fixedly connected between the two lifting rods 8. A lead screw 101 is rotatably connected to the support beam 81. The lead screw 101 and the carrier plate 9 are connected by a screw thread. By controlling the rotation of the lead screw 101, the up and down movement of the carrier plate 9 can be controlled by the screw thread. The connecting flange 11 is connected to a placement plate 112 located on the top of the water cannon body 1 through an arc plate 111. When in use, the placement plate 112 is in contact with the upper surface of the carrier plate 9.

[0049] The bottom of the support beam 81 is fixedly connected to a drive motor 102. The output end of the drive motor 102 is fixedly connected to the bottom of the lead screw 101. The drive motor 102 controls the rotation of the lead screw 101 and has a motor control function.

[0050] Working principle: There are three states during use:

[0051] The first type is the maintenance state, where the number of water cannon bodies 1 above the control rail 2 is less than the number of water cannon bodies 1 below the control rail 2. The water cannon bodies 1 located below are lower in height and are located on the outside of the fire dike, making it convenient for maintenance personnel to carry out regular maintenance along the way using a maintenance vehicle.

[0052] The second state is the switching maintenance state. When maintenance is required on the water cannon body 1 above the guide rail 2, the corresponding drive shaft 722 is controlled to rotate, driving the drive wheel 71 to rotate. The slide 3 slides onto the pivot rail 5, and the pivot rail 5 is controlled to rotate 180 degrees. At this time, the corresponding water cannon body 1 is located below the guide rail 2. Then, the slide 3 on the water cannon body 1 is controlled to slide onto the guide block 4. Then, the water cannon body 1 that was originally located below the guide rail 2 and has been maintained is moved to the pivot rail 5. The pivot rail 5 is controlled to reset, which can realize the switching of the two water cannon bodies 1. At this time, the water cannon body 1 with the reduced height after replacement can be maintained, which has the advantage of convenient and comprehensive rotational maintenance.

[0053] In the third state, when a fire occurs, the sliding blocks 3 on each water cannon body 1 below the guide rail 2 are controlled to slide onto the hub rail 5 in turn. Then, the hub rail 5 is controlled to rotate 180 degrees, and the sliding blocks 3 on the water cannon body 1 are controlled to slide to provide fixed-point support.

[0054] In the fourth state, when it is necessary to replace the unqualified water cannon body 1, control the water cannon body 1 to be replaced to move onto the pivot rail 5, control the pivot rail 5 to flip, and the water cannon body 1 on it will be inverted. Then control the lead screw 101 to rotate, the height of the carrier plate 9 will rise and contact the placement plate 112. At this time, remove the bolts on the connecting flange 11, and then control the carrier plate 9 to reset. The height of the water cannon body 1 to be replaced will be lowered. Similarly, the qualified water cannon body 1 can be installed.

[0055] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
