Description

Technical Field

[0001] This utility model relates to the field of testing device technology, and in particular to a testing device for a fire water supply system. Background Technology

[0002] In today's society, fire safety is of paramount importance. As a critical infrastructure in firefighting and rescue operations, the stable operation of fire water supply systems directly impacts the safety of people's lives and property. Fire water supply systems must be kept in good working order at all times to ensure a rapid and effective supply of sufficient and compliant fire-fighting water in the event of a fire.

[0003] With the development of fire protection technology and people's increased awareness of fire safety, the testing of fire water supply systems has become increasingly refined and rigorous. Water quality and water pressure are two core indicators for evaluating the performance of fire water supply systems, and accurate monitoring of these is essential. Currently, most fire water supply system testing devices on the market use a method where the testing end is placed directly inside the water supply pipeline, resulting in the testing end being in constant contact with water.

[0004] Firefighting water supply sources are complex and diverse, encompassing municipal tap water, natural water bodies (such as rivers, lakes, and reservoirs), and pre-treated reclaimed water. These waters often contain varying levels of dissolved oxygen, various mineral ions (such as chloride and sulfate ions), microorganisms, and potentially contaminated particles. The detection device, constantly immersed in such complex water, inevitably faces severe corrosion challenges. Prolonged exposure to corrosive environments not only damages the structural integrity of the detection device, leading to decreased detection accuracy, data deviations, fluctuations, and even malfunctions, but also fails to accurately reflect the true water quality and pressure conditions of the firefighting water supply system, posing a significant risk of misjudgment to the maintenance and management of the system. Furthermore, severe corrosion damages the detection device, requiring frequent replacements, which increases equipment and labor costs and may leave the firefighting water supply system in a monitoring blind spot during replacement, posing a potential threat to fire safety. Therefore, this invention proposes a firefighting water supply system detection device. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art where corrosion causes damage to the detection end, requiring frequent replacement of detection components. This not only increases equipment maintenance and labor costs but may also leave the fire water supply system in a monitoring blind spot during replacement, posing a potential threat to fire safety. Therefore, this invention proposes a fire water supply system detection device.

[0006] The technical solution of this utility model is as follows: A fire-fighting water supply system testing device, comprising a testing tank, with connecting pipes for connecting to water supply pipelines installed on both sides of the testing tank; a fixed plate fixedly connected to the inner wall of the testing tank, and a piston plate slidably connected to the testing tank below the fixed plate; a first through hole on the fixed plate and a second through hole on the piston plate for guiding water from the water supply system to the top of the fixed plate for testing; and two sets of on / off control components, the two sets of on / off control components being respectively installed on the top of the fixed plate and the piston plate, and the two sets of on / off control components being used to control the first through hole. The system includes: a control mechanism for connecting and disconnecting a first through hole and a second through hole; a first control mechanism mounted on the testing tank, which drives a set of on / off control components at the position of the first through hole; a second control mechanism mounted on the testing tank, which drives a set of on / off control components at the position of the second through hole; multiple sets of push rod motors mounted on the top of the testing tank, the output ends of which pass through the top of the testing tank and the fixing plate and are fixedly connected to the piston plate; a discharge pipe connected to the top of the testing tank, on which a solenoid valve is provided; and multiple sets of testing modules mounted on the top wall of the testing tank.

[0007] Optionally, the on / off control component includes a fixedly installed limiting ring with an L-shaped cross-section. A baffle is rotatably connected in the limiting ring, and the first through hole, the second through hole, and the baffle are all fan-shaped.

[0008] Optionally, the limiting ring in the on / off control assembly above the fixed plate is fixedly connected to the top of the fixed plate and corresponds to the position of the first through hole; the limiting ring in the on / off control assembly above the piston plate is fixedly connected to the top of the piston plate and corresponds to the position of the second through hole.

[0009] Optionally, the first control mechanism includes a first mounting bracket installed on the top of the detection tank. The first mounting bracket is arranged in a "U" shape. A first servo motor is installed on the top of the first mounting bracket. The output end of the first servo motor passes through the first mounting bracket and is fixedly connected to a connecting rod. The connecting rod passes through the top of the detection tank and is fixedly connected to a set of baffles above the fixed plate.

[0010] Optionally, the second control mechanism includes a second mounting bracket installed on the top of the detection tank. The second mounting bracket is U-shaped. A second servo motor is installed on the top of the second mounting bracket. The output end of the second servo motor passes through the second mounting bracket and is fixedly connected to a first gear. A second gear is provided on one side of the first gear and meshes with it. A rotating block is fixedly connected to the second gear. A positioning block is rotatably connected to the outside of the rotating block. The positioning block is fixedly connected to the top of the detection tank. A synchronizing rod is slidably connected to the rotating block. The synchronizing rod is quadrangular prism-shaped. The synchronizing rod passes through the top of the detection tank and the fixing plate and is fixedly connected to a set of baffles above the piston plate.

[0011] Optionally, a protective cover is installed on the top of the testing tank, and the discharge pipe penetrates the protective cover.

[0012] Optionally, a control module is provided on the top of the detection tank, and the first servo motor, the second servo motor, the push rod motor, the solenoid valve, and the detection module are all electrically connected to the control module.

[0013] Optionally, rubber rings are provided for sealing at the positions where the connecting rod penetrates the detection tank, the synchronous rod penetrates the detection tank and the fixed plate, and the output end of the push rod motor penetrates the detection tank and the fixed plate.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] This invention utilizes the coordinated operation of the detection tank, fixed plate, piston plate, and on / off control components to allow water to enter the detection area at the top of the fixed plate only when detection is required. At other times, the detection end is isolated from water, greatly reducing the contact time between the detection module and water. This effectively avoids corrosion caused by long-term immersion in water, extends the service life of the detection device, reduces maintenance costs and replacement frequency, and ensures the continuity of fire water supply system detection work.

[0016] Furthermore, by electrically connecting the control module installed on the top of the detection tank to the first servo motor, the second servo motor, the push rod motor, the solenoid valve, and the detection module, fully automated operation is achieved. Operators only need to issue commands on the control terminal to remotely control the entire detection process, including steps such as water flow introduction, detection module start-up, and liquid discharge after detection. This not only improves detection efficiency and reduces human error, but also adapts to complex fire water supply system monitoring environments. For example, it can reliably complete detection tasks in some areas that are difficult for humans to access or in dangerous areas.

[0017] In summary, this invention can effectively prevent corrosion at the detection end, extend the service life of the device, reduce maintenance and replacement costs, and ensure the continuity of detection work. Attached Figure Description

[0033] The components of the present invention embodiments described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0037] Example

[0038] like Figures 1 to 4 As shown, this utility model proposes a testing device for a fire-fighting water supply system, including a testing tank 1. Connecting pipes 11 for connecting to water supply pipelines are installed on both sides of the testing tank 1. The testing tank 1 serves as the core outer shell of the entire testing device, protecting internal components, bearing water pressure, and providing a stable flow space for water. Its material is typically high-strength, corrosion-resistant metal or alloy to ensure structural integrity even under the complex environment of long-term contact with fire-fighting water supply. The connecting pipes 11 are responsible for seamless connection with external fire-fighting water supply pipelines. They generally adopt a standard pipe diameter design for easy and quick installation and disassembly, while ensuring smooth water flow. Sealing gaskets are often provided at the interfaces to prevent leakage at the connection points, ensuring that the entire testing process is not interfered with by external pipeline connection problems.

[0039] Specifically, the above-mentioned detection device includes a fixed plate 2 fixedly connected to the inner wall of the detection tank 1, a piston plate 3 slidably connected to the detection tank 1 below the fixed plate 2, a first through hole 21 on the fixed plate 2, and a second through hole 31 on the piston plate 3, for guiding water from the water supply system to the top of the fixed plate 2 for detection.

[0040] Furthermore, the aforementioned detection device also includes two sets of on / off control components 4. These two sets of on / off control components 4 are respectively installed on the top of the fixed plate 2 and the piston plate 3, and are used to control the opening and closing of the first through hole 21 and the second through hole 31. Each on / off control component 4 includes a fixedly installed limiting ring 41 with an L-shaped cross-section. A baffle 42 is rotatably connected within the limiting ring 41, providing stable lateral support for the baffle 42 and preventing it from shifting during movement. The first through hole 21, the second through hole 31, and the baffle 42 are all fan-shaped, facilitating the control of the on / off state by covering the first through hole 21 and the second through hole 31 with the baffle 42. The limiting ring 41 in the on / off control component 4 installed above the fixed plate 2 is fixedly connected to the top of the fixed plate 2 and corresponds to the position of the first through hole 21; the limiting ring 41 in the on / off control component 4 installed above the piston plate 3 is fixedly connected to the top of the piston plate 3 and corresponds to the position of the second through hole 31.

[0041] It is worth mentioning that the above-mentioned detection device includes a first control mechanism 5 installed on the detection tank 1. The first control mechanism 5 is used to drive a set of on / off control components 4 at the position of the first through hole 21. The first control mechanism 5 includes a first mounting bracket 51 installed on the top of the detection tank 1. The first mounting bracket 51 is U-shaped. A first servo motor 52 is installed on the top of the first mounting bracket 51, and the positions of the first mounting bracket 51 and the first servo motor 52 are fixed. The output end of the first servo motor 52 passes through the first mounting bracket 51 and is fixedly connected to a connecting rod 53. The connecting rod 53 passes through the top of the detection tank 1 and is fixedly connected to a set of baffles 42 above the fixed plate 2. After the first servo motor 52 is started, it drives the set of baffles 42 to rotate through the connecting rod 53.

[0042] Furthermore, the aforementioned detection device includes a second control mechanism 6 mounted on the detection tank 1. The second control mechanism 6 is used to drive a set of on / off control components 4 at the position of the second through hole 31. The second control mechanism 6 includes a second mounting bracket 61 mounted on the top of the detection tank 1. The second mounting bracket 61 is U-shaped, and a second servo motor 62 is mounted on the top of the second mounting bracket 61. The positions of the second mounting bracket 61 and the second servo motor 62 are fixed. The output end of the second servo motor 62 passes through the second mounting bracket 61 and is fixedly connected to a first gear 63. A second gear 64 is provided on one side of the first gear 63 and meshes with it. After the second servo motor 62 is started, it drives the second gear 64 to rotate through the first gear 63. A rotating block 65 is fixedly connected to the second gear 64, and a positioning block 66 is rotatably connected to the outside of the rotating block 65. The positioning block 66 is fixedly connected to the top of the detection tank 1, and the positioning block 66 keeps the rotating block 65 in its original position. A synchronizing rod 67 is slidably connected to the rotating block 65. The synchronizing rod 67 is a quadrangular prism, which allows it to slide within the positioning block 66. Simultaneously, the rotation of the positioning block 66 drives the synchronizing rod 67 to rotate. The synchronizing rod 67 passes through the top of the detection tank 1 and the fixing plate 2, and is fixedly connected to a set of baffles 42 above the piston plate 3. The synchronizing rod 67 and the set of baffles 42 move synchronously.

[0043] Furthermore, the aforementioned detection device includes two sets of push rod motors 7 installed on the top of the detection tank 1. The output end of the push rod motor 7 passes through the top of the detection tank 1 and the fixed plate 2 and is fixedly connected to the piston plate 3. It is used to drive the piston plate 3 to move. When the first through hole 21 is open and the second through hole 31 is closed, it drives the piston plate 3 to move closer to the fixed plate 2, squeezing the water between the fixed plate 2 and the piston plate 3 to the top of the fixed plate 2, and then discharging it through the discharge pipe 8. Thus, after the piston plate 3 is reset, the water is kept away from the detection module 9, preventing the detection module 9 from rusting.

[0044] Furthermore, the above-mentioned detection device includes a discharge pipe 8 connected to the top of the detection tank 1. A solenoid valve 81 is installed on the discharge pipe 8. A protective cover 12 is installed on the top of the detection tank 1. The discharge pipe 8 passes through the protective cover 12. When the solenoid valve 81 is opened, and the first through hole 21 and the second through hole 31 are opened at the same time, the water in the water supply system directly passes through the discharge pipe 8 and comes into contact with the detection module 9.

[0045] Multiple detection modules 9, installed on the top wall of the detection tank 1, consist of various high-precision sensors, including water quality sensors (such as those detecting pH, dissolved oxygen, and heavy metal content) and water pressure sensors. Based on their advanced detection principles, these sensors can collect key data on fire-fighting water supply in real time and accurately, providing reliable data for the maintenance and management of the fire-fighting water supply system. For example, the pH sensor in the water quality sensor uses the glass electrode method to accurately measure the hydrogen ion concentration in the water, reflecting the acidity or alkalinity of the water; the water pressure sensor uses the principle of pressure-to-electrical signal conversion to accurately measure the water pressure value of the water supply system, ensuring that the fire-fighting water supply system is always in good operating condition and guaranteeing fire safety. A control module is installed on the top of the detection tank 1. The first servo motor 52, the second servo motor 62, the push rod motor 7, the solenoid valve 81, and the detection modules 9 are all electrically connected to the control module. As the "brain" of the entire device, the control module integrates a microprocessor, memory, communication interface, and other electronic components, possessing powerful information processing and command transmission capabilities. On one hand, it receives instructions from operators via the control terminal, parses and processes these instructions using built-in algorithms, and then coordinates the actions of various components to achieve fully automated operation. Operators only need to issue instructions via the control terminal to remotely control the entire detection process, including steps such as water introduction, activation of detection module 9, and post-detection liquid discharge, greatly improving detection efficiency and reducing human error.

[0046] Rubber rings are installed at the positions where the connecting rod 53 penetrates the detection tank 1, the synchronous rod 67 penetrates the detection tank 1 and the fixed plate 2, and the output end of the push rod motor 7 penetrates the detection tank 1 and the fixed plate 2 to effectively prevent liquid leakage.

[0047] In this embodiment, during testing, the first servo motor 52 is activated, driving a set of upper baffles 42 to rotate via the connecting rod 53, thus opening the first through hole 21. Then, the second servo motor 62 is activated, driving the second gear 64 to rotate via the first gear 63, and driving the synchronous rod 67 to rotate via the rotating block 65, thereby opening the second through hole 31. At this time, water from the water supply system passes through the second through hole 31 and the first through hole 21 sequentially to reach the top of the fixed plate 2. Simultaneously, the solenoid valve 81 is open and automatically closes after two seconds, facilitating the removal of air from the detection tank 1 and preventing excessive water outflow. At this time, the detection module 9 is in full contact with the water in the water supply system, allowing for the detection of water quality and pressure. After the detection is completed, the second servo motor 62 is activated, closing the second through hole 31. The two sets of push rod motors 7 are activated to retract and move the piston plate 3 upwards, simultaneously opening the solenoid valve 81 to discharge the water above the piston plate 3. Afterwards, the solenoid valve 81 is opened, and the push rod motors 7 move the piston plate 3 back to its original position, increasing the space between the fixed plate 2 and the piston plate 3. This keeps water away from the detection module 9, preventing it from rusting when not in use and extending its service life.

[0048] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
