DETAILED DESCRIPTION

[0050] The specific embodiments of the utility model will be further described in detail below in combination with the drawings and examples. The following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

[0051] As Figures 1 to 5 shown, the adjustable flow fire-fighting equipment of the utility model, comprising:

[0052] The carrier 1 is independently arranged on the ground;

[0053] The water inlet assembly 2 is arranged on the carrier 1 and is used to convey fire-fighting water;

[0054] The water spraying mechanism 3 is arranged on the water inlet assembly 2 and is in communication with the water inlet assembly 2, is used to adjust the flow of water and spray water;

[0055] The lifting mechanism 4 is arranged on the carrier 1 and is used to adjust the vertical height of the water inlet assembly 2;

[0056] The water spraying mechanism 3 further comprises:

[0057] The control valve 31 is in communication with the water inlet assembly 2;

[0058] The positioning seat 32 is arranged at the outer end of the control valve 31, and a plurality of positioning holes 36 are arranged on the positioning seat 32;

[0059] The flow control valve plate 33 is swingably arranged inside the control valve 31 and is used to control the flow of water;

[0060] The adjusting handle 34 is swingably arranged on the positioning seat 32 and is used to control the swing of the flow control valve plate 33;

[0061] The locking handle 35 is swingingly arranged on the adjusting handle 34, and a torsion spring is arranged on the swing axis of the locking handle 35, and a clamping block is arranged on the locking handle 35; under the action of the torsion spring, the outer end of the locking handle 35 is pushed to swing away from the adjusting handle 34, the other end of the locking handle 35 drives the clamping block to swing to be close to the positioning hole 36, until the clamping block is inserted into the corresponding positioning hole 36, and the clamping block is matched with the positioning hole 36, so that the fixing of the adjusting handle 34 is realized, and the swing of the adjusting handle 34 is prevented;

[0062] The conveying pipe 37 is communicatively arranged on the control valve 31;

[0063] The spraying pipe 38 is swingingly arranged on the conveying pipe 37, and is used for spraying the fire-fighting water;

[0064] The working process and principle of the device are as follows: the carrier 1 is independently arranged on the ground to ensure stability; the water inlet assembly 2 is connected through a water source to ensure that the fire-fighting water can be smoothly conveyed; the vertical height of the water inlet assembly 2 is adjusted according to actual needs by the lifting mechanism 4 to adapt to different fire extinguishing scenes; the firefighter first observes the fire situation and judges the required water flow size; the flow control valve plate 33 inside the control valve 31 is swung by swinging the adjusting handle 34, so as to change the size of the water flow channel and realize the adjustment of the flow; after the adjustment is completed, the clamping block on the locking handle 35 is matched with the positioning hole 36 on the positioning seat 32, and the adjusting handle 34 is fixed by the action of the torsion spring to prevent the flow setting from being changed due to accidental touch or vibration during the fire extinguishing process; according to the specific position of the fire situation, the firefighter can swing the spraying pipe 38 to adjust the direction and angle of water spraying; the swing arrangement of the spraying pipe 38 enables the firefighter to flexibly adjust the water spraying direction without moving the entire device, thereby improving the fire extinguishing efficiency; when the flow and direction are adjusted, the firefighter can open the switch of the water inlet assembly 2, and the fire-fighting water starts to be sprayed through the control valve 31, the conveying pipe 37 and the spraying pipe 38 to extinguish the fire source; the position of the flow control valve plate 33 inside the control valve 31 is changed by swinging the adjusting handle 34, so as to adjust the size of the water flow channel; the larger the channel, the larger the water flow; the smaller the channel, the smaller the water flow; the cooperation of the locking handle 35 and the positioning hole 36 ensures that the adjusting handle 34 can stably remain at the required position after the adjustment is completed, preventing the flow from being changed due to accidental touch; the accurate adjustment of the flow and the flexible adjustment of the water spraying direction are realized, effectively solving the problems of insufficient flexibility and adjustability of traditional fire-fighting equipment in complex and variable fire situations, and improving the fire extinguishing efficiency and safety.

[0065] As shown in Figure 2 , the water spraying mechanism 3 further comprises:

[0066] The handle 3a is fixedly installed on the spraying pipe 38;

[0067] The sliding sleeve 3b is slidably sleeved on the handle 3a;

[0068] A fixing bolt 3c is threadedly inserted into the sleeve 3b. When the fixing bolt 3c is screwed, the bottom end of the fixing bolt 3c is tightly attached to the surface of the handle 3a, thereby fixing the position of the sleeve 3b and preventing the sleeve 3b from sliding, and further fixing the angle of the spray pipe 38;

[0069] A hinged strip 3d is swingably installed on the conveying pipe 37, and the top end of the hinged strip 3d is hinged to the sleeve 3b;

[0070] The working process and principle of the water spraying mechanism 3 are as follows: the firefighter first adjusts the water spraying direction by swinging the spray pipe 38. At this time, the hinged strip 3d serves as a bridge connecting the conveying pipe 37 and the sleeve 3b, allowing the spray pipe 38 to swing freely within a certain range. After the preliminary adjustment is completed, the firefighter can further fine-tune the angle of the spray pipe 38 by sliding the position of the sleeve 3b on the handle 3a. Since the top end of the hinged strip 3d is hinged to the sleeve 3b, the sliding of the sleeve 3b will drive the spray pipe 38 to adjust the angle within a smaller range. When the angle of the spray pipe 38 is adjusted to the optimal position, the firefighter tightens the fixing bolt 3c, making its bottom end tightly attached to the surface of the handle 3a. Due to the threaded connection between the fixing bolt 3c and the sleeve 3b, the position of the sleeve 3b is firmly fixed, and further the angle of the spray pipe 38 is fixed through the hinged strip 3d. By adding the handle 3a, the sleeve 3b, the fixing bolt 3c, and the hinged strip 3d, the water spraying mechanism 3 not only realizes accurate flow regulation, but also has flexible adjustment and fixing functions of the water spraying direction. This makes the firefighting equipment more efficient and safe when dealing with complex fire conditions.

[0071] As shown in Figure 1 and Figure 4 The water inlet assembly 2 includes:

[0072] An elbow 21 is arranged on the carrier 1 and used to introduce firefighting water;

[0073] A flexible hose 22 is fixedly connected with the elbow 21 and communicates with each other;

[0074] A flow divider 23 is arranged on the lifting mechanism 4, and the bottom end of the flow divider 23 is fixedly connected with the top end of the flexible hose 22;

[0075] Two flow divider valves 24 are both arranged on the flow divider 23 in communication;

[0076] The working process and principle of the water inlet component 2 are as follows: When the fire-fighting equipment is deployed to the fire scene, the fire-fighting water needs to be introduced into the equipment through the elbow 21; the elbow 21 is connected to the fire-fighting water source to ensure that the fire-fighting water can enter the equipment smoothly; the introduced fire-fighting water enters the telescopic hose 22 through the elbow 21; the telescopic hose 22 has a certain degree of flexibility and extensibility, which can adapt to the layout requirements of different scenarios, while ensuring the smooth transmission of water flow; the top of the telescopic hose 22 is firmly connected to the distributor 23; the distributor 23 is set on the lifting mechanism 4 and moves up and down with the lifting mechanism 4; the main function of the distributor 23 is to distribute the incoming fire-fighting water to different outlets to adapt to the needs of multiple sprinklers or multiple tasks.

[0077] It also includes a valve cover 25, which is installed on the port of the diversion valve 24. The valve cover 25 plays an important role in protecting the port of the diversion valve 24. It can prevent external impurities, dust or moisture from entering the interior of the diversion valve 24, thereby keeping the valve clean and in normal working condition. A tight seal is formed between the valve cover 25 and the port of the diversion valve 24. This sealing performance can ensure that fire water will not leak from the valve port when the fire equipment is working, thereby ensuring the overall performance and efficiency of the equipment.

[0078] It also includes a chain 26, which is securely connected to the valve cover 25, and the other end of the chain 26 is securely connected to the outer end face of the diversion valve 24. The chain 26 is to provide an additional safety or fixing mechanism to ensure that the valve cover 25 can be stably held on the port of the diversion valve 24 without being manually removed. The presence of the chain 26 forms a physical barrier to prevent the valve cover 25 from accidentally falling off or being lost, thus maintaining the overall performance and reliability of the fire-fighting equipment.

[0079] It also includes a lock bolt 27, which is threadedly inserted into the valve cover 25. Tightening the lock bolt 27 makes its bottom end fit tightly against the surface of the diverter valve 24, fixing the position of the valve cover 25 and preventing it from falling off. The lock bolt 27 is threadedly inserted into the valve cover 25. By tightening the lock bolt 27, its bottom end can fit tightly against the surface of the diverter valve 24. As the lock bolt 27 rotates, it gradually moves downward until its bottom end is in close contact with the surface of the diverter valve 24. This close contact generates a frictional force that prevents the valve cover 25 from moving or falling off accidentally. Even under vibration or impact, the lock bolt 27 can provide sufficient holding force to ensure that the valve cover 25 remains in place.

[0080] like Figure 5 As shown, the lifting mechanism 4 includes:

[0081] The lifting bracket 41 is fixedly installed on the carrier 1;

[0082] A screw rod 42 is rotatably arranged in the lifting support 41;

[0083] A threaded sleeve 43 is sleeved on the screw rod 42 and threadedly cooperates with the screw rod 42;

[0084] Two guide columns 44 are fixedly arranged on the threaded sleeve 43 and slidably arranged in the lifting support 41;

[0085] A motor 45 is fixedly arranged at the bottom end of the lifting support 41 and used for driving the screw rod 42 to rotate;

[0086] A lifting plate 46 is fixedly connected with the top ends of the two guide columns 44, and the lifting plate 46 is fixedly connected with the shunt 23;

[0087] The working process and principle of the lifting mechanism 4 are as follows: when the height of the water inlet assembly 2 needs to be adjusted, the motor 45 is started; the motor drives the screw rod 42 to rotate to generate a rotating power; since the threaded sleeve 43 threadedly cooperates with the screw rod 42, when the screw rod 42 rotates, the threaded sleeve 43 moves up and down along the axial direction of the screw rod; the guide columns 44 slide in the lifting support 41 to ensure that the lifting process of the threaded sleeve 43 and the lifting plate 46 is stable and accurate in direction; with the up and down movement of the threaded sleeve 43, the lifting plate 46 and the shunt 23 thereon also move up and down, so that the height adjustment of the water inlet assembly 2 is realized; when the required height is reached, the motor 45 is stopped, and the lifting mechanism is locked at the current position; the lifting mechanism realizes the height adjustment of the water inlet assembly 2 through the driving of the motor, the thread cooperation of the screw rod and the threaded sleeve, and the guiding effect of the guide columns; both the stability and accuracy of the lifting process are ensured, and the automatic control of the lifting is realized.

[0088] The lifting mechanism 4 further comprises:

[0089] Two guide rails 47 are fixedly arranged on the lifting support 41;

[0090] Two guide sliding blocks 48 are fixedly arranged on the threaded sleeve 43 and slidably cooperated with the two guide rails 47, respectively;

[0091] During the up and down movement of the threaded sleeve 43, the guide sliding blocks 48 slide on the guide rails 47 to provide stable guidance for the threaded sleeve 43, prevent the threaded sleeve 43 from deviating or shaking during the lifting process, improve the accuracy and reliability of the lifting, and enable the water inlet assembly 2 to accurately reach the required height.

[0092] The adjustable flow fire-fighting equipment of the utility model, its installation mode, connection mode or setting mode are all common mechanical modes, as long as the beneficial effects can be achieved.

[0093] The above merely is the preferred implementation manner of the present application, and it should be noted that, for the ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present application.
