Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and in particular to a vehicle-mounted hydraulic testing system. Background Technology

[0002] Fire trucks are the core equipment for fire and rescue operations, and their hydraulic performance directly affects the effectiveness of fire fighting and rescue. Accurately testing hydraulic performance is of great significance for ensuring the normal operation of fire trucks and efficient fire fighting.

[0003] When fire and rescue teams conduct fire truck acceptance, annual inspection, and decommissioning, they face testing challenges. Most fire brigades lack the specialized equipment and facilities to test the hydraulic performance of fire trucks. Furthermore, due to the large size and limited mobility of fire trucks, as well as factors such as transportation and site distance, it is difficult to transport them to designated quality inspection centers for testing. This is inconvenient, increases costs, and hinders the operation of their services.

[0004] Existing hydraulic testing solutions for fire trucks have significant shortcomings. A common approach is a fixed flow detection system, which involves constructing test pipelines of different diameters (e.g., DN50, DN100, DN200) to meet various flow rate requirements for routine flow testing. However, this system is permanently installed and cannot be taken to the fire station for on-site testing. Fire trucks must travel to a fixed location, which contradicts the actual operational need for on-site testing and fails to meet the requirements for conducting firefighting operations.

[0005] In addition, while some mobile testing equipment exists on the market, its functionality is limited. Fire trucks employ various extinguishing methods during actual firefighting operations, each with different requirements for hydraulic performance. Existing mobile equipment, due to its functional limitations, cannot fully meet the testing needs of multiple extinguishing methods, making it difficult to accurately assess the hydraulic performance of fire trucks and providing a reliable basis for performance evaluation and optimization.

[0006] It is evident that existing technologies cannot meet the hydraulic performance testing needs of fire and rescue teams in fire truck-related operations. Therefore, it is essential to develop a versatile vehicle-mounted hydraulic testing system capable of on-site testing. Utility Model Content

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] The purpose of this invention is to provide a vehicle-mounted hydraulic testing system to solve the problems existing in the prior art. By setting a water detection module, a foam detection module, and an air detection module on the vehicle body, it is possible to simultaneously detect the flow rate and pressure of water, foam, and air, thus realizing a mobile hydraulic testing system capable of on-site testing of various fire extinguishing methods.

[0042] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] like Figures 1 to 11 As shown, this utility model provides a vehicle-mounted hydraulic testing system, including one or more water detection modules, one or more foam detection modules, one or more air detection modules 4, and a vehicle body 8. The water detection module includes a first test pipeline, a first flow meter, a first pressure gauge, and a first valve. The first flow meter, first pressure gauge, and first valve are all installed in the first test pipeline. The first flow meter and first pressure gauge are used to test the flow rate and pressure of water flowing through the first test pipeline, respectively. The first valve is used to control the opening degree or closing of the first test pipeline. The foam detection module includes a second test pipeline, a second flow meter, a second pressure gauge, and a second valve. The second flow meter, second pressure gauge, and second valve are all installed in the second test pipeline. The second flow meter and second pressure gauge are used to test the flow rate and pressure of foam flowing through the second test pipeline, respectively. The second valve is used to control the opening degree or closing of the second test pipeline. The air detection module 4 includes a third test pipeline, a third flow meter, a third pressure gauge, and a third valve. The third flow meter, third pressure gauge, and third valve are all installed in the third test pipeline. The third flow meter and third pressure gauge are used to test the flow rate and pressure of the air flowing through the third test pipeline, respectively. The third valve is used to control the opening and closing of the third test pipeline. The water detection module, foam detection module, and air detection module 4 are all installed on the vehicle body 8. The vehicle body 8 can move and drive the overall movement of each detection module.

[0044] This utility model provides a water detection module, a foam detection module, and an air detection module 4 on the vehicle body 8. Each detection module is equipped with a flow meter and a pressure gauge on the test pipeline. The flow meter and pressure gauge can simultaneously detect the flow rate and pressure of water, foam, and air flowing through each test pipeline, thus realizing a mobile hydraulic testing system capable of on-site testing of various fire extinguishing methods.

[0045] In one embodiment, the first test pipeline has a water inlet at one end and a water outlet at the other. The water inlet is used to connect to the fire truck being tested. The first flow meter is positioned near the water outlet to stabilize the water flow over a certain length of pipeline, avoiding the influence of turbulence near the water inlet, thus ensuring that the first flow meter measures a stable flow rate and improving measurement accuracy. The second test pipeline has a foam inlet at one end and a foam outlet at the other. The foam inlet is used to connect to the fire truck being tested. The second flow meter is positioned near the foam outlet to stabilize the foam liquid over a certain length of pipeline, avoiding the influence of turbulence near the foam inlet, thus ensuring that the second flow meter measures a stable flow rate and improving measurement accuracy. The third test pipeline has an air inlet at one end and an air outlet at the other. The air inlet is used to connect to the fire truck being tested. The third flow meter is positioned near the air outlet to stabilize the air flow over a certain length of pipeline, avoiding the influence of turbulence near the air inlet, thus ensuring that the third flow meter measures a stable flow rate and improving measurement accuracy.

[0046] In this example, the first flow meter can be an electromagnetic flow meter, with different specifications selected based on the diameter of the first test pipeline; the first valve can be a manual gate valve, with different specifications selected based on the diameter of the first test pipeline. The second flow meter can be an electromagnetic flow meter, with different specifications selected based on the diameter of the second test pipeline; the second valve can be a manual ball valve, with different specifications selected based on the diameter of the second test pipeline. The third flow meter can be a vortex flow meter, with different specifications selected based on the diameter of the third test pipeline; the third valve can be a manual ball valve, with different specifications selected based on the diameter of the third test pipeline.

[0047] In one embodiment, the water detection module is configured with four groups: Water Detection Module 1 (3), Water Detection Module 2 (5), Water Detection Module 3 (6), and Water Detection Module 4 (7). The first test pipelines for the four groups of water detection modules are DN50 pipeline (31), DN100 pipeline (51), DN150 pipeline (61), and DN200 pipeline (71), respectively. The multiple pipe diameters allow for the testing of fire trucks using water-based extinguishing media of different pipe diameters. Furthermore, the first flow meters installed on the first test pipelines are Water Flow Meter 1 (32), Water Flow Meter 2 (52), Water Flow Meter 3 (62), and Water Flow Meter 4 (72), respectively; the first valves installed on the first test pipelines are Water Valve 1 (33), Water Valve 2 (53), Water Valve 3 (63), and Water Valve 4 (73), respectively.

[0048] In one embodiment, the foam detection module is provided in two sets, namely foam detection module 1 and foam detection module 2. The second test pipelines of the two sets of foam detection modules are DN3 pipeline 11 and DN15 pipeline 21, respectively. The multiple pipe diameters can be used to test fire trucks with foam extinguishing media of different pipe diameters. In addition, the second flow meters provided in the second test pipeline are foam flow meter 12 and foam flow meter 22, respectively; the second valves provided in the second test pipeline are foam valve 13 and foam valve 23, respectively.

[0049] In one embodiment, the air detection module 4 is provided in a set, and the third test pipeline of the set of air detection modules 4 is a DN65 pipeline 41. In addition, the third flow meter provided in the third test pipeline is an air flow meter 42, and the third valve provided in the third test pipeline is an air valve 43.

[0050] In one embodiment, the first test pipeline (DN50 pipeline 31, DN100 pipeline 51, DN150 pipeline 61 and DN200 pipeline 71), the second test pipeline (DN3 pipeline 11 and DN15 pipeline 21), and the third test pipeline (DN65 pipeline 41) are arranged in parallel in ascending order of pipe diameter, with the arrangement sequence being DN3 pipeline 11, DN15 pipeline 21, DN50 pipeline 31, DN65 pipeline 41, DN100 pipeline 51, DN150 pipeline 61 and DN200 pipeline 71. The length direction is the width direction of the vehicle body 8. That is to say, the inlet and outlet of each pipeline are distributed on both sides of the vehicle body 8. This facilitates the connection of each pipeline during testing. Each pipeline is relatively independent and does not affect each other. Moreover, the above arrangement can save space, allowing multiple pipelines to be integrated and arranged within the limited space of the vehicle body 8.

[0051] In this example, each pipeline is located near the rear of the vehicle body 8, and the pipelines are arranged sequentially from the front to the rear of the vehicle according to their diameter from small to large. Meanwhile, since the DN200 pipeline 71 is relatively large and is located behind the rear wheel, it can be installed in a recessed manner to reserve installation and operation space above, further optimizing the arrangement of each pipeline in the vehicle body 8.

[0052] In one embodiment, the foam inlet direction of DN3 pipe 11 is the same as that of DN15 pipe 21, and the water inlet direction of DN50 pipe 31 is opposite to that of DN15 pipe 21. The water inlet directions of DN50 pipe 31, DN65 pipe 41, DN100 pipe 51, DN150 pipe 61, and DN200 pipe 71 are alternately arranged in opposite directions. Since each pipe is equipped with a flow meter, pressure gauge, and valve, and all are close to the outlet side, the alternating opposite inlet directions of the pipes can avoid interference between the flow meters, pressure gauges, and valves, making the pipes closer together and reducing the space occupied in the vehicle length direction.

[0053] In one embodiment, a drainage module is also included. The drainage module includes a drainage channel and drainage holes. The drainage channel is positioned on the vehicle body 8 corresponding to the water outlet and foam outlet. The drainage hole is located at the bottom of the drainage channel and connects to the outside of the vehicle body 8. During relevant tests, the medium in each pipeline can be directly sprayed to the outside of the vehicle body 8. However, the medium remaining in the pipeline cannot be directly sprayed to the outside of the vehicle body 8 and is collected through the drainage channel and discharged through the drainage hole. This prevents the accumulation of foam, water, and other media inside the vehicle body 8, thereby reducing or preventing corrosion and other damage to the vehicle body 8.

[0054] In one embodiment, a control and display system module is also included. This module includes a touch panel, a memory, and a processor. The touch panel displays flow and pressure information and allows for touch operation. The memory stores test data and built-in software, and may also include a perpetual calendar. The processor processes the data. The water detection module, foam detection module, air detection module 4, and drainage module 4 are connected together, forming an on-board hydraulic testing system.

[0055] In this example, the control display system module can directly display the instantaneous flow rate and instantaneous pressure of each pipeline. It can also select water, foam, and air pipelines to display individually on the screen. The foam detection module includes an additional parameter, "foam ratio," which is calculated based on the instantaneous flow rates of water and foam measured by the system. The calculation of the foam ratio is as follows:

[0056] Foam ratio = foam flow rate / (water flow rate + foam flow rate) × 100%;

[0057] The utility model concentrates a large-scale fixed flow detection system into a small-scale vehicle-mounted hydraulic test system, which is convenient for testers to transport to the location of the fire truck to enable off-site operation. The whole vehicle-mounted hydraulic test system has a high degree of integration, convenient operation, and complete display functions. The medium (low)-pressure water flow test range covers 1.5 L / s to 200 L / s, the high-pressure water flow test range covers 1.5 L / s to 50 L / s, the foam liquid flow test range covers 0.003 L / s to 1.6 L / s, and the maximum air test flow rate ≥ 10 Nm 3 / min, and the test accuracy can reach ±1%.

[0058] Refer again to Figures 1 to 11 , the utility model provides a test method for a vehicle-mounted hydraulic test system. Applying the vehicle-mounted hydraulic test system described above, it includes the following steps:

[0059] S1. Select the first test pipeline, the second test pipeline, and / or the third test pipeline to connect the hydraulic system of the fire truck to be tested with the vehicle-mounted hydraulic test system;

[0060] S2. Adjust the opening degrees of the first valve, the second valve, and / or the third valve to control the flow rate and pressure to meet the detection requirements;

[0061] S3. Display the instantaneous flow rate and instantaneous pressure of the first test pipeline, the second test pipeline, and / or the third test pipeline on the control display system module, and judge whether it is qualified, for example, whether it meets the industry or national standards;

[0062] S4. Disconnect the connection between the hydraulic system of the fire truck to be tested and the vehicle-mounted hydraulic test system, and discharge the remaining water and foam through the drainage module to complete the detection.

[0063] In step S2, the water used for fire extinguishing has a certain pressure and stability, and the spraying distance and flow rate need to be stably met the design requirements. Therefore, the "pressure-flow matching" of the hydraulic system on the fire truck is required. During the actual detection process, the pipeline can be pressurized by adjusting the valve opening degree to test the rated pressure and rated flow rate. If the rated pressure and rated flow rate can be achieved, it is qualified. When simulating the outlet opening degree of the fire monitor or fire gun through the valve opening degree, for example, a pressure of 1.0 MPa, a flow rate of 80 L / s, and a range of 85 m are required. However, if the valve opening degree reaches the maximum, the pressure may only be 0.5 MPa or lower, and although the flow rate reaches 80 L / s, the range is only 40 m or 50 m. At this time, the test requirements cannot be met. Therefore, the valve opening degree needs to be adjusted to meet the test requirements.

[0064] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
