Description

Technical Field

[0001] The invention relates to the technical field of fire fighting, and in particular to a fire hose detection mechanism. Background Art

[0002] Fire hose testing is an important part of ensuring the quality and performance of fire hoses. The main purpose of fire hose testing is to evaluate its reliability and safety in practical applications. Through testing, the physical and chemical properties, mechanical properties of fire hoses, and whether they meet relevant standards and application requirements can be confirmed, thereby ensuring that they can perform at their best in an emergency.

[0003] The fire hose testing mechanism is mainly composed of a water pressure source, a specimen fixture, a computer integrated control cabinet, a safety measure structure, etc. The water pressure source is one of the core parts of the testing machine and is responsible for providing stable water pressure for the test. The specimen fixture is used to clamp and fix the fire hose specimen to ensure that it will not move or fall off during the water pressure test. The computer integrated control cabinet is the intelligent control center of the testing machine, integrating various sensors, controllers and data processing equipment.

[0004] In the existing technical solutions, when the fire hose is being tested, it is mostly clamped and fixed by a specimen fixture to ensure that it does not move or fall off during the water pressure test. The specimen fixture usually ensures the stability of the fire hose joint by a large clamping force. However, this excessive clamping force sometimes causes unnecessary damage to the fire hose joint, especially after long-term clamping or multiple uses; due to the large clamping force, the fire hose joint is often difficult to disassemble, which not only increases the labor intensity of the operator, but may also prolong the detection time and reduce the detection efficiency.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The present invention provides a technical solution: See also Figures 1 to 6A fire hose detection mechanism includes a workbench 1, an assembly fixing seat 11 is fixedly installed on the left side wall inside the workbench 1, an assembly movable seat 2 is movably installed on the right end inside the workbench 1, and a sealing assembly component 3 is arranged inside the assembly movable seat 2 and the assembly fixing seat 11. The sealing assembly component 3 includes a connector 302 fixedly installed inside the assembly movable seat 2 and the assembly fixing seat 11, and the right side of the right connector 302 is fixedly connected to a water supply main pipe 5; a locking boosting component 6 is arranged inside the connector 302, and the locking boosting component 6 includes a partitioning fixed block 608 fixedly installed inside the connector 302, and the connector 302 is provided with a partitioning fixed block 608 located inside the partitioning fixed block An arc-shaped boosting groove 601 is on the clockwise side of 608, and a return spring 606 is fixedly installed on the side wall of the clockwise side of the partitioning fixed block 608. A boosting push rod 602 fixedly connected to the return push spring 606 is slidably installed inside the boosting groove 601; an arc-shaped locking groove 603 is provided inside the connecting head 302 and located on the counterclockwise side of the partitioning fixed block 608, and a locking push rod 604 is slidably installed inside the locking groove 603; a rope through hole 607 is provided inside the partitioning fixed block 608, and a connecting pull rope 605 is slidably installed inside the rope through hole 607, and the two ends of the connecting pull rope 605 are respectively fixedly connected to the boosting push rod 602 and the locking push rod 604.

[0025] The sealing assembly component 3 also includes an engaging groove 304 provided on the outer end surface of the connecting head 302, an elastic sealing bag ring 305 is embedded inside the engaging groove 304, a connecting water supply pipe 306 is connected on the inner side wall of the elastic sealing bag ring 305, a connecting water pipe 307 is fixedly connected on the side wall of the elastic sealing bag ring 305 away from the water supply main 5, the elastic sealing bag ring 305 is connected to the connecting head 302 through the connecting water supply pipe 306, the elastic sealing bag ring 305 is connected to the locking slide groove 603 through the connecting water pipe 307, an assembly sleeve 301 is detachably installed on the outer wall of the connecting head 302, a clamping groove 303 is provided on the top outer wall of the connecting head 302, the structure of the clamping groove 303 is an L-shaped structure and four are provided, a clamping block 308 corresponding to the clamping groove 303 is fixedly installed on the inner wall of the assembly sleeve 301, and the end of the assembly sleeve 301 away from the connecting head 302 is fixedly connected to the sample water hose 4.

[0026] By adopting the above technical solution, when using, select a fire hose sample that can represent the performance of the entire batch of hoses, ensure that the sample is not damaged or stained, connect the sample hose 4 to the water supply main pipe 5 through the assembly sleeve 301 and the connector 302, so that high-pressure water can be supplied to the sample hose 4 through the water supply main pipe 5, and the sample hose 4 is tested. When assembling the sample hose 4, insert the clamping block 308 on the assembly sleeve 301 into the corresponding clamping groove 303 and rotate it, so that the clamping groove 303 and the clamping block 308 are aligned, so that the clamping groove 303 and the clamping block 308 are clamped, providing conditions for subsequent locking and boosting, thereby improving the convenience of the sample hose 4 during assembly. When testing, high-pressure water is injected into the sample hose 4 through the water supply main pipe 5, and the high-pressure water injected through the water supply main pipe 5 can be supplied to the elastic sealing bag ring 305 through the connector 302 and the connected water supply pipe 306. When a large amount of liquid is filled into the elastic sealing bag ring 305, the elastic sealing bag ring 305 can expand in the fitting groove 304, so that part of the elastic sealing bag ring 305 can expand out of the fitting groove 304, so that the expanded part of the elastic sealing bag ring 305 can fit with the inner wall of the assembly sleeve 301, thereby ensuring the sealing of the connection of the fire hose during inspection. By interconnecting and cooperating with the elastic sealing bag ring 305 and the water supply main pipe 5 and the sample water hose 4, the water pressure inside the elastic sealing bag ring 305 can be made the same as the water pressure inside the water supply main pipe 5 and the sample water hose 4. In this way, the force with which the elastic sealing bag ring 305 fits the inner wall of the assembly fitting 301 can change with the change of water pressure, thereby reducing the risk of leakage caused by water pressure fluctuations or improper operation, and realizing elastic changes in the sealing effect, so that the sealing effect is enhanced with the increase of water pressure, and thus stable sealing performance can be maintained under various water pressure conditions; the stable sealing effect ensures the stability of the water flow during the test, thereby improving the accuracy of the test, and the enhancement of the sealing effect also reduces potential safety hazards caused by leakage, making the test process safer.

[0027] When there is sufficient liquid inside the elastic sealing ring 305, the liquid inside the elastic sealing ring 305 will be supplied to the locking groove 603 through the connecting water pipe 307. The continuous increase of water pressure in the locking groove 603 can push the locking push rod 604 in the locking groove 603 to slide out of the locking groove 603, so that the sliding locking push rod 604 can tighten the clamping block 308 inserted into the clamping groove 303, which can improve the stability of the clamping block 308 during assembly and connection. At this time, the sliding locking push rod 604 can drive the connecting rope 605 to move, and the other end of the connecting rope 605 is connected to the boosting push rod 602 through the rope through hole 607. It should be noted here that there is sufficient sealing between the connecting rope 605 and the rope through hole 607 to avoid liquid leakage from the connection. In this way, the boosting push rod 602 can be pulled to retract into the boosting slide groove 601, and the retracted boosting push rod 602 can compress the retraction push spring 606. By means of the interconnection and coordination between the locking groove 603, the connecting water pipe 307 and the elastic sealing bag ring 305, the locking push rod 604 can play the effect of hydraulic fixing and compression on the clamping block 308. At the same time, the hydraulic pressure inside the locking groove 603 changes with the change of the water pressure inside the water supply main pipe 5 and the sample water belt 4, so that the locking push rod 604 can adapt to the clamping block 308 according to the tightening demand. Moreover, the hydraulic fixing and compression method is more stable than the traditional mechanical locking because the hydraulic pressure can be evenly distributed between the locking push rod 604 and the clamping block 308. This design reduces the risk of loosening or falling off due to vibration or external force. By adjusting the water pressure of the water supply main pipe 5, the degree of tightening of the locking push rod 604 on the clamping block 308 can be easily controlled without complicated mechanical adjustment. This makes the operation easier and faster, and improves work efficiency.

[0028] When the sample water hose 4 to be tested needs to be replaced, the water supply main 5 stops supplying water, and the liquid inside the locking chute 603 will flow back into the connecting water pipe 307, the elastic sealing bag ring 305, the connecting water supply pipe 306 and the connecting head 302, while there is no pressure in the locking chute 603. Therefore, under the recovery of the elastic force of the retreat top spring 606, the booster push rod 602 can be pushed to slide out of the booster chute 601, so that the card block 308 that is connected can be pushed by the booster push rod 602 to move, which can facilitate the rotation and movement of the assembly sleeve 301, and then facilitate the removal of the assembly sleeve 301 from the connecting head 302. Through the cooperation between the booster push rod 602, the retreat top spring 606 and the connecting rope 605, the fire hose can be automatically replaced in time when the fire hose is replaced. The assembly sleeve 301 of the sample water hose 4 is automatically retracted and relaxed, so as to improve the convenience of the sample water hose 4 during replacement and improve the efficiency of replacing the sample water hose 4; through the automatic coordination of the booster rod 602, the retraction spring 606 and the connecting pull rope 605, the cumbersome need for manual disassembly of the sample water hose 4 is reduced, which not only saves manpower, but also reduces the equipment damage or safety risks that may be caused by improper human operation, and the automatic retraction and relaxation process can ensure that the assembly sleeve 301 will not be deformed or damaged by external force during the replacement process, thereby ensuring the accuracy and stability of the detection equipment. In addition, the automatic retraction mechanism can also prevent fatigue and misoperation caused by long-term manual operation, and further protect the equipment from damage.

[0029] Specifically, Figures 1 to 4 and Figure 7 As shown, a drive test component 7 is provided at the right end of the inner side of the workbench 1, and the drive test component 7 includes a limit assembly groove 704 opened on the lower right end surface of the inner side of the workbench 1, and a servo motor 701 fixed inside the workbench 1 is provided on the right side of the limit assembly groove 704, and the output end of the servo motor 701 is fixedly connected to a screw rod 702 located inside the limit assembly groove 704, and a screw rod nut 703 is provided on the outside of the screw rod 702, and the screw rod nut 703 is fixedly connected to the assembly movable seat 2.

[0030] By adopting the above technical solution, when in use, the initial position of the assembly movable seat 2 is installed on the left end of the screw rod 702 through the screw nut 703. At this time, the spacing between the assembly movable seat 2 and the assembly fixed seat 11 is small, so it is convenient to install the assembly sleeves 301 at both ends of the sample water hose 4 to the connecting heads 302 on the assembly movable seat 2 and the assembly fixed seat 11. After installation, the servo motor 701 is started. The servo motor 701 can drive the screw rod 702 to rotate. The spiral groove on the screw rod 702 interacts with the steel ball in the circulator groove in the screw nut 703, so that the screw nut 703 can move linearly along the axis of the screw rod 702, thereby driving the assembly movable seat 2 fixedly connected to the screw nut 703 to move together in the limit assembly groove 704. The setting of the limit assembly groove 704 can ensure stability during pulling, so that the fire hose can be pulled during the detection process. The pulling process can simulate the tensile force that the fire hose is subjected to in actual use, so as to evaluate its maximum bearing capacity under tensile conditions. This helps to confirm whether the fire hose can maintain its integrity and functionality when subjected to tensile force, and is an important means to evaluate its durability and reliability in emergency situations. In emergency situations such as fire fighting and rescue, firefighters need to rely on water hoses for effective water transportation. If the water hose is prone to rupture or leakage when stretched, it will seriously affect the rescue effect. Therefore, testing the tensile strength of the water hose through pulling can ensure that the water hose can be used normally in emergency situations, thereby improving the efficiency and safety of firefighting work.

[0031] Specifically, Figure 1 , Figures 7 to 9 As shown, a mounting groove 10 is provided on the bottom end surface of the inner side of the workbench 1, and an extrusion friction component 9 is arranged inside the mounting groove 10. The extrusion friction component 9 includes an assembly frame 901 fixed on the bottom end surface of the mounting groove 10, a first motor 902 is fixedly installed on the left end of the assembly frame 901, a motor seat 903 is rotatably installed inside the assembly frame 901, a second motor 904 is fixedly installed inside the motor seat 903, a friction pressurizing component 8 is arranged at the output end of the second motor 904, and the friction pressurizing component 8 includes a friction rod 802 fixed at the output end of the second motor 904, a water pressure channel 803 is arranged inside the friction rod 802, and the friction A pressure supply manifold 801 that is interconnected with the water pressure channel 803 is rotatably installed at the front end of the friction rod 802, and the other end of the pressure supply manifold 801 is connected to the water supply main 5. An assembly sliding cavity 806 is provided on the inner wall of the friction rod 802, and a fixed seat 804 is fixedly installed at one end of the assembly sliding cavity 806 close to the water pressure channel 803, and a connecting water hole 805 is provided in the middle position of the fixed seat 804. A spring 807 is fixedly connected to one end of the fixed seat 804 away from the water pressure channel 803, and a friction protrusion 808 is fixedly connected to one end of the spring 807 away from the fixed seat 804, and the friction protrusion 808 is slidably connected to the assembly sliding cavity 806.

[0032] By adopting the above technical solution, when in use, the movement of the driving test component 7 can ensure that the sample water hose 4 is in a straightened state. At this time, the first motor 902 in the installation slot 10 is started. The first motor 902 is powered on to drive the motor seat 903 in the assembly frame 901 to rotate, which can change the angle of the second motor 904. At the same time, the second motor 904 is started, which can drive the friction rod 802 to rotate. In this way, through the rotation of the first motor 902 and the second motor 904 and the pulling of the driving test component 7, the friction rod 802 and the outer surface of the water-filled and straightened sample water hose 4 can be rubbed against each other, and the water-filled and straightened sample water hose 4 is closer to the actual use state. The friction between 802 and its outer surface can simulate the wear and tear that the hose may encounter in actual use. By testing the degree of wear of the hose under friction conditions, its wear resistance can be evaluated, thereby ensuring the reliability and durability of the hose in actual use. Through the rotation coordination of the motor, the friction test is automated, reducing manual operation and thus improving the detection efficiency. The motor drive can maintain a constant speed and force to ensure continuity and stability during the test and avoid errors that may be caused by manual operation. The friction test under motor drive can set fixed parameters, such as speed, friction time, etc., to ensure the standardization of each test and improve the accuracy of the test results.

[0033] During the inspection, the water pressure channel 803 inside the friction rod 802 is connected to the pressure supply manifold 801, so that the pressure supply manifold 801 can guide the water in the water supply main pipe 5 into the water pressure channel 803. When there is high-pressure water inside the water pressure channel 803, the liquid inside the water pressure channel 803 will flow into the assembly slide cavity 806 through the connecting water hole 805 on the fixed seat 804. The water pressure in the assembly slide cavity 806 increases, thereby pushing the friction protrusion 808 to slide out of the assembly slide cavity 806. At the same time, the spring 807 can be pulled to extend when the assembly slide cavity 806 slides out. It should be noted here that there is a good sealing effect between the friction protrusion 808 and the assembly slide cavity 806 to prevent the liquid from flowing out from the connection between the friction protrusion 808 and the assembly slide cavity 806, and the length of the friction protrusion 808 extending from the assembly slide cavity 806 is It is controllable to prevent the friction protrusion 808 from sliding out and falling from the assembly slide cavity 806. When there is no hydraulic action, the friction protrusion 808 can be pulled back into the assembly slide cavity 806 under the elastic recovery of the spring 807. Under the cooperation of the set friction protrusion 808, the friction rod 802 and the second motor 904, by accurately controlling the motor speed and the shape, size and distribution of the friction protrusion 808, various friction conditions that the fire hose may encounter in actual use can be simulated, so as to more accurately evaluate its wear resistance. This standardized detection method helps to reduce errors caused by human factors and improve the accuracy of detection; by adjusting the rotation angle, speed and configuration of the friction protrusion 808 of the first motor 902 and the second motor 904, it can adapt to the detection needs of fire hoses of different specifications and materials, and has strong adaptability and flexibility. In addition, the water pressure in the assembly slide cavity 806 is the same as the water pressure in the sample water hose 4, so that there is sufficient hydraulic force to drive the friction protrusion 808 to extend from the assembly slide cavity 806, and then the friction protrusion 808 and the surface of the sample water hose 4 are fitted together to achieve friction detection. When the water pressure in the assembly slide cavity 806 is set to be the same as the water pressure in the sample water hose 4, it can be ensured that the pressure on the friction protrusion 808 during the extension process is uniform, thereby avoiding friction detection errors caused by uneven pressure. The uniform pressure distribution enables the friction protrusion 808 to more realistically simulate the friction conditions experienced by the fire hose in actual use, thereby improving the accuracy of friction detection. Water pressure, as a driving force, is stable and controllable. By accurately controlling the size of the water pressure, the extension speed and force of the friction protrusion 808 can be accurately regulated, thereby enhancing the stability of friction detection. Water is supplied to the sample water hose 4 through the water supply main 5, and in conjunction with the drive test component 7, the friction pressure component 8 and the extrusion friction component 9, the fire hose can be subjected to a pressure test while simultaneously undergoing elongation, expansion rate tests, wear resistance tests, etc., thereby ensuring the integrity of the fire hose's performance during testing.

[0034] Working principle: When in use, select a fire hose sample that can represent the performance of the entire batch of hoses, ensure that the sample is not damaged or stained, connect the sample hose 4 to the water supply main 5 through the assembly joint 301 and the connecting joint 302, so that high-pressure water can be supplied to the sample hose 4 through the water supply main 5, and the sample hose 4 is tested. When assembling the sample hose 4, insert the clamping block 308 on the assembly joint 301 into the corresponding clamping groove 303 and rotate it, so as to ensure that the clamping groove 303 is aligned with the clamping block 308, so that the clamping groove 303 and the clamping block 308 are clamped, which provides conditions for subsequent locking and boosting, thereby improving the convenience of the sample hose 4 during assembly. During the test, high-pressure water is injected into the sample water hose 4 through the water supply main pipe 5. The injection of high-pressure water through the water supply main pipe 5 can enable the high-pressure water to be supplied to the elastic sealing bag ring 305 through the connecting head 302 and the connecting water supply pipe 306. When a large amount of liquid is filled into the elastic sealing bag ring 305, the elastic sealing bag ring 305 can expand in the fitting groove 304, so that part of the elastic sealing bag ring 305 can expand out of the fitting groove 304, so that the expanded part of the elastic sealing bag ring 305 can fit with the inner wall of the assembly sleeve 301, thereby ensuring the sealing of the connection of the fire hose during the test. When there is sufficient liquid inside the elastic sealing bag ring 305, the liquid inside the elastic sealing bag ring 305 will be supplied to the locking groove 603 through the connecting water pipe 307. The continuous increase in water pressure in the locking groove 603 can push the locking push rod 604 in the locking groove 603 to slide out of the locking groove 603, so that the sliding locking push rod 604 can tighten the clamping block 308 inserted into the clamping groove 303, which can improve the stability of the clamping block 308 during assembly and connection. At this time, the sliding locking push rod 604 can drive the connecting rope 605 to move, and the other end of the connecting rope 605 is connected to the boosting push rod 602 through the rope hole 607. It should be noted here that there is sufficient sealing between the connecting rope 605 and the rope hole 607 to avoid the problem of liquid leakage from the connection. In this way, the boosting push rod 602 can be pulled to retract into the boosting slide groove 601, and the retracted boosting push rod 602 at this time can achieve compression of the retreat push spring 606. Through the mutual connection and cooperation of the locking slide groove 603, the connecting water pipe 307 and the elastic sealing bag ring 305, the locking push rod 604 can play the effect of hydraulic fixing and compression on the clamping block 308.When the sample water belt 4 to be tested needs to be replaced, the water supply main 5 stops supplying water, and the liquid inside the locking chute 603 will flow back into the connecting water pipe 307, the elastic sealing bag ring 305, the connecting water supply pipe 306 and the connector 302, while there is no pressure in the locking chute 603. Therefore, under the recovery of the elastic force of the retreating top spring 606, the boosting push rod 602 can be pushed out of the boosting chute 601, so that the card connected by the boosting push rod 602 can be pushed. The connecting block 308 moves, which can facilitate the rotational movement of the assembly sleeve 301, and then facilitate the removal of the assembly sleeve 301 from the connecting head 302. Through the cooperation of the booster rod 602, the retraction spring 606 and the connecting pull rope 605, the assembly sleeve 301 of the sample water hose 4 can be automatically retracted and relaxed when replacing the fire hose, thereby improving the convenience of the sample water hose 4 during replacement and improving the efficiency of replacing the sample water hose 4.

[0035] When in use, the initial position of the assembly movable seat 2 is installed on the left end of the screw rod 702 through the screw nut 703. At this time, the spacing between the assembly movable seat 2 and the assembly fixed seat 11 is small, so it is convenient to install the assembly sleeves 301 at both ends of the sample water hose 4 to the connectors 302 on the assembly movable seat 2 and the assembly fixed seat 11. After installation, start the servo motor 701. The servo motor 701 can drive the screw rod 702 to rotate. The spiral groove on the screw rod 702 interacts with the steel ball in the circulator groove in the screw nut 703, so that the screw nut 703 can move linearly along the axis of the screw rod 702, thereby driving the assembly movable seat 2 fixedly connected to the screw nut 703 to move together in the limit assembly groove 704. The setting of the limit assembly groove 704 can ensure the stability during the pulling process, and the movement of the driving test assembly 7 can ensure that the sample water hose 4 is in a straightened state. At this time, start the first motor 902 in the installation slot 10. When the first motor 902 is powered on, it can drive the motor seat 903 in the assembly frame 901 to rotate, which can change the angle of the second motor 904. At the same time, the second motor 904 is started, which can drive the friction rod 802 to rotate. By rotating the first motor 902 and the second motor 904 and cooperating with the pulling of the driving test component 7, the friction rod 802 and the outer surface of the water-filled and stretched sample water hose 4 can be made to rub against each other. During the test, the water pressure channel 803 inside the friction rod 802 is connected to the pressure supply manifold 801, so that the pressure supply manifold 801 can guide the water in the water supply main pipe 5 into the water pressure channel 803. When there is high-pressure water inside the water pressure channel 803, the liquid inside the water pressure channel 803 will flow into the assembly slide cavity 806 through the connecting water hole 805 on the fixed seat 804. The increase of water pressure in the assembly slide cavity 806 can push the friction protrusion 808 to slide out of the assembly slide cavity 806. At the same time, when the assembly slide cavity 806 slides out, the spring 807 can be pulled to extend. When there is no hydraulic action, the friction protrusion 808 can be pulled back into the assembly slide cavity 806 under the elastic recovery of the spring 807, and the water pressure in the assembly slide cavity 806 is the same as the water pressure in the sample water belt 4, so that there can be sufficient hydraulic force to drive the friction protrusion 808 to extend out of the assembly slide cavity 806, thereby making the friction protrusion 808 and the surface of the sample water belt 4 fit each other to realize friction detection.
