Description

Technical Field

[0001] The present invention belongs to the technical field related to fire pumps, and more specifically, particularly relates to an intelligent and safe fire water pump with improved stability. Background Art

[0002] The intelligent fire pump is a mechatronic device that can start and supply water in a short time. It is a high-tech product that integrates microelectronics technology, digital technology, computer technology, information processing technology, industrial automation control technology, communication technology and mechanical technology.

[0003] When a fire occurs or emergency water is needed, the fire pump can be used to quickly and conveniently perform pressurized water delivery and output operations. However, the fire pumps in the prior art still have the following defects:

[0004] 1. The fire pump in the prior art usually carries out water delivery after the output interface is connected to the pipeline. The output port of the fire pump is usually in a fixed direction, and the fire hose is a soft belt. Therefore, during the firefighting operation, the user or firefighter usually needs to run through the water outlet at the end of the fire hose to output water flow to extinguish the fire. Therefore, during the dragging process, the water hose at the docking end of the water hose is prone to folding due to the fixed direction of the fire pump and the output port, which affects the instability of the water flow;

[0005] 2. The docking end of the fire pump in the prior art does not have the function of adjusting the hose body. Therefore, in actual use, after the fire hose is pulled and moved, the fire hose near the output interface will bend, fold, and other problems will affect the service life of the hose. At the same time, there is a problem that the flow cross-section changes due to the folding, making the water flow output speed unstable;

[0006] 3. The intelligence of the intelligent fire pump in the prior art is usually in the aspects of intelligent start and stop, noise and vibration control, etc., but in actual use, the problem is that when the water hose is dragged to move the output water flow, the direction of the pump body output port is fixed, which causes interference to the dragging water hose and the bending of the water hose at the docking end causes unstable water pressure. The fire pump in the prior art cannot realize intelligent adjustment of the direction of the pump output end.

[0007] Therefore, in view of this, research and improvement are conducted on the existing structure and defects, and an intelligent and safe fire water pump with improved stability is provided, in order to achieve a more practical purpose. Summary of the invention

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In the present invention, an intelligent safety fire pump with improved stability is provided with an interface direction adjustment function. In the prior art, a fire pump is usually connected to a pipeline through an output interface to carry out water delivery operations, and the output port direction of the fire pump is usually fixed, while the fire hose is a soft belt. Therefore, during the firefighting operation, the user or firefighter usually needs to run through the water outlet at the end of the fire hose to output water flow for fire extinguishing. Therefore, during the dragging process, the water hose at the docking end of the water hose is prone to folding due to the fixed direction of the fire pump and the output port, which affects the instability of the water flow. In the present invention, the deflection output cylinder is rotatably embedded in the rotating sealing groove of the fixed top seat and the fixed base through the symmetrical embedded ring body parts on the upper and lower outer walls, and the rotating seal is realized by the embedded sealing ring. Therefore, during actual use, when the firefighter drives the fire hose to move, the water hose will drive the deflection output cylinder to rotate under the dragging of the water hose, so that the docking port follows the dragging of the water hose to deviate in the direction angle, so as to avoid the problem of squeezing the water flow and affecting the flow caused by the folding of the docking end water hose during the operation of using the fire hose;

[0022] The intelligent safety fire pump with improved stability of the present invention not only has the function of adjusting the direction of the interface, but also can realize the active support and adjustment function of the water hose at the docking end. The docking end of the fire pump in the prior art does not have the water hose pipe body adjustment function. Therefore, in actual use, after the fire hose is pulled and moved, the fire hose near the output interface part will bend, fold and other problems will occur, which will affect the service life of the water hose. At the same time, there is a problem that the flow cross-section changes due to folding, making the water flow output speed unstable. At the same time, even if the direction of the docking port can be adjusted, in actual use, if the water hose is pulled and dragged too quickly or excessively, there will still be a problem that the water hose is bent near the docking end, affecting the output stability of the docking port. In the present invention, in actual use, the hydraulic control box hydraulic control pump can be used to pass the oil through the hydraulic transmission port, the hydraulic transmission groove, the docking groove, the hydraulic connecting channel, The functional linkage groove and the hydraulic ring groove are connected to the electromagnetic valve and input into the functional carrying ring cavity through the docking hydraulic channel to push the carrying ring frame to slide. The supporting functional tube drives the deflection supporting tube to push the supporting monitoring end head out of the end head recovery groove and place it in the fire hose. The supporting monitoring end head can achieve the supporting effect of the fire hose connection section. It can avoid the problem that the belt body of the fire hose connection end is folded during the pulling and dragging process, causing the fitting of the docking port to affect the water flow output efficiency. At the same time, by energizing and retracting the electromagnetic telescopic rod in the monitoring carrying ring, it can be achieved that the transmission pull wire is pressed downward by the pull wire hook body, so that the deflection support tube is deflected outward under the pulling, so that the supporting monitoring end head is deflected outward to form a stronger supporting effect on the inside of the fire hose, thereby avoiding the problem that the water hose is pulled and dragged, and the water hose is bent near the docking end, affecting the stability of the water flow output.

[0023] In the present invention, an intelligent and safe fire pump with improved stability can realize intelligent and active following deflection through the combined function of the direction and the support function inside the fire hose, further reducing the problem of bending and folding of the hose docking end affecting the water output effect. The intelligence of the intelligent fire pump in the prior art is usually in the aspects of intelligent start and stop, noise and vibration control, etc., but in actual use, the problem is that when the hose is dragged to move the output water flow, the direction of the pump body output port is fixed, which causes interference in dragging the hose and the bending of the hose at the docking end causes water pressure instability. The fire pump in the prior art cannot realize intelligent adjustment of the direction of the pump output end, while in the present invention, the support monitoring end is supported on the inner side of the fire hose to form a supporting effect. During the dragging process, the angle deflection of the fire hose and the dragging with the ground will cause The pressure-sensitive value on the corresponding side changes, thereby monitoring the pressure-sensitive module in the ring to obtain analysis data and upload it to the control terminal to judge and transmit instructions. The annular electromagnet is energized to push the lifting slide plate to slide downward, so that the docking gear ring is engaged with the internal gear part of the transmission, and the deflection motor drives the transmission shaft to rotate, so that the rotation angle of the deflection output cylinder follows the movement direction of the firefighters to perform a follow-up deflection function, thereby realizing the deflection in advance before the fire hose is bent through the active deflection effect, thereby further reducing the problem of dragging and moving the hose docking end under pressure affecting the stability of the water flow. At the same time, when the docking gear ring is undocking, the deflection motor can also be used to drive the transmission shaft to rotate, so that the functional docking ring seat drives the compensation mounting shaft and the compensation booster wheel to rotate, and the active boost compensation output function can be realized according to the water flow and pressure.

[0056] Specific use of the present invention:

[0057] During firefighting, the fire pump motor 17 is started, and the motor shaft drives the impeller to rotate at high speed in the impeller booster housing 19, so that the impeller booster housing 19 draws water from the water inlet port 22, and the two sets of rotors in the impeller booster housing 19 rotate at high speed, and the internal cavity continuously changes in volume, so that the water is pressurized and discharged from the booster output port 24, passes through the water output cavity 58 and the water output port 59, and is connected to the docking port 70 by installing a fire hose of a fire hose gun to perform firefighting;

[0058] An intelligent and safe fire pump with improved stability of the present invention is provided with an interface direction adjustment function. Fire pumps in the prior art usually carry out water delivery operations after the output interface is connected to the pipeline, and the output port direction of the fire pump is usually fixed, and the fire hose is a soft belt. Therefore, during the firefighting operation, the user or firefighter usually needs to run to output water flow through the water spray port at the end of the fire hose to extinguish the fire. Therefore, during the dragging process, the water hose at the docking end of the water hose is easily folded due to the fixed direction of the fire pump and the output port, which affects the water flow. Stability problem, and in the present invention, the deflection output cylinder 51 is embedded and rotatably arranged in the rotation sealing groove 54 of the fixed top seat 52 and the fixed base 53 through the embedded ring body 56 of the upper and lower outer walls, and the rotation sealing is realized by the embedded sealing ring 57. Therefore, in the actual use process, when the firefighter drives the fire hose to move, the water hose will drive the deflection output cylinder 51 to rotate, so that the docking port 70 follows the dragging of the water hose to deviate in the direction angle, so as to avoid the problem of squeezing the water flow and affecting the flow of the water hose caused by the folding of the docking end water hose during the operation of using the fire hose;

[0059] The intelligent safety fire pump with improved stability of the present invention not only has the function of adjusting the interface direction, but also can realize the active support and adjustment function of the water hose at the docking end. The docking end of the fire pump in the prior art does not have the water hose pipe body adjustment function. Therefore, in actual use, after the fire hose is pulled and moved, the fire hose near the output interface part will bend, fold and other problems will occur, affecting the service life of the water hose. At the same time, there is a problem that the flow cross-section changes due to folding, making the water flow output speed unstable. At the same time, even if the direction of the docking port can be adjusted, in actual use, if the water hose is pulled and dragged too quickly or excessively, there is still a problem that the water hose is bent near the docking end, affecting the output stability of the docking port 70. In the present invention, in actual use, the hydraulic control box 26 hydraulic control pump can be used to transfer oil through the hydraulic transmission port 36, the hydraulic transmission groove 49, the docking groove 61, the hydraulic connecting channel 62, the functional linkage groove 63, the hydraulic ring The hydraulic pressure of the hydraulic pressure pipe 78 is used to push the monitoring terminal 80 to extend from the terminal recovery groove 39 and place it in the fire hose. The monitoring terminal 80 can support the fire hose connection section, thereby avoiding the problem that the belt body of the fire hose connection end is folded during the pulling and dragging process, causing the fitting of the docking port 70 to affect the water flow output efficiency. At the same time, the electromagnetic telescopic rod in the monitoring carrying ring 81 is energized and retracted, and the transmission pull wire 72 can be pressed and pulled downward by the pull wire hook body 85, so that the deflection support tube 78 is deflected outward under the pulling, so that the monitoring terminal 80 is deflected outward to form a stronger support effect on the inner side of the fire hose, thereby avoiding the problem that the water hose is pulled and dragged, causing the water hose to bend near the docking end and affect the stability of the water flow output.

[0060] In the present invention, an intelligent and safe fire pump with improved stability can realize intelligent and active following deflection through the combined function of the direction and the support function inside the fire hose, further reducing the problem of bending and folding of the hose docking end affecting the water output effect. The intelligence of the intelligent fire pump in the prior art is usually in the aspects of intelligent start and stop, noise and vibration control, etc., but in actual use, the problem is that when the hose is dragged to move and output water flow, the direction of the pump body output port is fixed, which causes interference in dragging the hose and the bending of the hose at the docking end causes water pressure instability. The fire pump in the prior art cannot realize intelligent adjustment of the direction of the pump output end, while in the present invention, the support monitoring end 80 is supported on the inner side of the fire hose to form a supporting effect. During the dragging process, the angle deflection of the fire hose and the dragging with the ground will cause the pressure-sensitive value of the corresponding side to change, thereby monitoring The pressure-sensitive module in the measuring and carrying ring 81 obtains the analysis data and uploads it to the control terminal 25 to realize the judgment and transmission of instructions. The annular electromagnet 92 is energized to push the lifting slide 94 to slide downward, so that the docking gear ring 99 is meshed and connected with the internal transmission gear portion 89, and the deflection motor 32 drives the transmission shaft 44 to rotate, so that the rotation angle of the deflection output cylinder 51 follows the movement direction of the firefighters to perform the following deflection function, thereby realizing the deflection in advance before the fire hose is bent through the active deflection effect, thereby further reducing the problem of the dragging movement causing the pressure on the docking end of the hose to affect the stability of the water flow. At the same time, when the docking gear ring 99 is undocking, the deflection motor 32 can also drive the transmission shaft 44 to rotate, so that the functional docking ring seat 90 drives the compensation installation shaft 95 and the compensation booster wheel 60 to rotate, and the active boost compensation output function can be realized according to the water flow and pressure.

Many modifications and variations will be apparent to those of ordinary skill in the art.
