Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figures 1 to 4 The fire sprinkler mounting frame shown includes a mounting block 1. A caster wheel 2 is mounted on the bottom of the mounting block 1. The caster wheel 2 is a swivel caster. A water cavity 3 and a sliding cavity 8 are formed inside the mounting block 1. The sliding cavity 8 is located below the water cavity 3 and communicates with the water cavity 3.

[0025] The mounting block 1 is equipped with an outlet pipe 15 and an inlet pipe 4 that are connected to the water chamber 3.

[0026] The water outlet pipe 15 is vertically placed on top of the mounting block 1, and the top opening of the water outlet pipe 15 is closed. The top of the water outlet pipe 15 is fixedly provided with a lug 14, and the nozzle 16 is rotatably mounted on the lug 14. A flexible hose 17 is fixedly connected between the nozzle 16 and the water outlet pipe 15.

[0027] In this embodiment, the nozzle 16 includes a head, a connecting part, and a handle. The head is the water spraying part. The connecting part is rotatably connected to the ear seat 14. The connecting part is located between the head and the handle, and both the head and the handle are fixedly connected to the connecting part.

[0028] The water inlet pipe 4 is placed horizontally on the side of the mounting block 1 and is fixedly connected to the mounting block 1. The water inlet pipe 4 is used to connect to the fire hydrant.

[0029] A second piston plate 9 is slidably installed inside the sliding cavity 8. A piston rod 10 and a spring 11 are vertically mounted at the bottom of the second piston plate 9. The piston rod 10 is fixedly connected to the second piston plate 9. The piston rod 10 extends downward through the mounting block 1 and is fixedly connected to the support assembly. The piston rod 10 and the mounting block 1 are in a sealed sliding fit.

[0030] Specifically, the support assembly includes a plate 12, which is located at the bottom of the mounting block 1 and is fixedly connected to the bottom end of the piston rod 10. Multiple support blocks 13 arranged in a matrix are fixedly disposed at the bottom end of the plate 12.

[0031] Spring 11 is sleeved on piston rod 10. The top end of spring 11 is fixedly connected to the second piston plate 9, and the bottom end is fixedly connected to the mounting block 1.

[0032] A pressure regulating component for adjusting water pressure is installed inside water chamber 3.

[0033] Specifically, the pressure regulating assembly includes a first piston plate 5. The first piston plate 5 is slidably installed inside the water chamber 3. A horizontally placed hydraulic rod 6 is fixedly installed on the mounting block 1, and the telescopic end of the hydraulic rod 6 is fixedly connected to the first piston plate 5. The water outlet pipe 15 and the water inlet pipe 4 are both connected to the rodless chamber of the water chamber 3.

[0034] The water pressure sensor 18 and the controller are fixedly installed on the mounting block 1. The probe of the water pressure sensor 18 extends into the rodless cavity of the water chamber 3. Both the water pressure sensor 18 and the hydraulic rod 6 are electrically connected to the controller.

[0035] The mounting block 1 has a water spray hole 7, which is connected to the rod cavity of the water cavity 3.

[0036] Operating principle: During firefighting, the entire mounting frame is pushed to a position close to the fire point. Then, the inlet pipe 4 is connected to the fire hydrant. The connection process is existing technology, and the inlet pipe 4 and the fire hydrant are connected via existing fire hoses.

[0037] Before the water inlet pipe 4 is connected to the fire hydrant, the connection between the sliding cavity 8 and the water cavity 3 is located in the rodless cavity of the water cavity 3.

[0038] After the inlet pipe 4 is connected to the fire hydrant, the fire hydrant is opened. At this time, fire-fighting water enters the rodless chamber of water chamber 3. Then, after the rodless chamber of water chamber 3 and the outlet pipe 15 are filled with fire-fighting water, the water pressure in the rodless chamber of water chamber 3 increases, and the water pressure on the second piston plate 9 increases.

[0039] When the water pressure on the second piston plate 9 exceeds the elastic force of the spring 11, the second piston plate 9 slides down and compresses the spring 11. At this time, the second piston plate 9 drives the piston rod 10 to slide down, the piston rod 10 pushes the plate 12 to move down, and the plate 12 drives the support block 13 to move down.

[0040] After the support block 13 contacts the ground, the support block 13, plate 12, piston rod 10, and second piston plate 9 stop moving, and the spring 11 stops being compressed. At this time, the water pressure detector 18 detects the water pressure in the rodless chamber of the water cavity 3 and converts the water pressure data into an electrical signal, which is then transmitted to the controller. In this embodiment, the area below the mounting block 1 is flat ground; if it is not flat, existing measures can be used to level the ground.

[0041] After the second piston plate 9 stops moving, the nozzle 16 is oriented towards the fire extinguishing point, and the nozzle 16 is opened simultaneously. Once the nozzle 16 is open, fire-fighting water is sprayed towards the fire extinguishing point. At the same time, the water pressure in the rodless chamber of water cavity 3 decreases. At this point, the water pressure detector 18 detects the decrease in water pressure in the rodless chamber of water cavity 3, and the controller controls the extension end of the hydraulic rod 6 to extend and push the first piston plate 5 to slide. During this process, the space of the rodless chamber of water cavity 3 decreases, thereby increasing the water pressure in the rodless chamber to offset the decrease in water pressure. If the water pressure in the rodless chamber increases during fire extinguishing, the controller controls the extension end of the hydraulic rod 6 to retract, thereby increasing the space of the rodless chamber of water cavity 3, and thus decreasing the water pressure in the rodless chamber to offset the increase in water pressure. In this embodiment, a microcontroller can be used as the controller.

[0042] During the process of adjusting the water pressure in the rodless cavity, the connection between the sliding cavity 8 and the water cavity 3 is always located in the rodless cavity.

[0043] After a period of firefighting, when it is necessary to approach the fire extinguishing point, the retractable end of the hydraulic rod 6 continuously extends and pushes the first piston plate 5 to slide continuously. When the first piston plate 5 slides to the center of the connection between the sliding cavity 8 and the rodless cavity, the telescopic shaft of the hydraulic rod 6 stops extending and retracting, and at the same time, the rodless cavity, the rod cavity, and the sliding cavity are connected. At this time, the water pressure in the water cavity 3 decreases rapidly. When the water pressure on the second piston plate 9 is less than the elastic force of the spring 11, the second piston plate 9 slides upward, the piston rod 10 moves upward, the plate 12 moves upward, and the support block 13 is lifted off the ground. After that, the mounting block 1 can be pushed closer to the fire extinguishing point. During this process, the sprinkler head 16 continuously sprays fire-fighting water to ensure that it is always in a fire-fighting state. When the rod cavity is full of fire-fighting water, the fire-fighting water is discharged through the sprinkler nozzle 7, thereby cooling the surrounding environment.

[0044] After the mounting block 1 is close to the fire extinguishing point and reaches a safe position, the telescopic end of the hydraulic rod 6 retracts again, causing the first piston plate 5 to slide. Once the connection between the sliding cavity 8 and the rodless cavity is completely within the rodless cavity again, the above process can be repeated to extinguish the fire.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
