Description

Technical Field

[0001] This utility model relates to the field of water tank testing technology, and in particular to a multifunctional water tank testing device. Background Technology

[0002] As an indispensable and important component of the rail transit system, water tanks are mainly used to store various types of water needed during train operation. Due to the special nature of the rail transit environment, water tanks are subject to vibration for a long time, which can lead to damage. Therefore, a multi-functional water tank testing device is needed.

[0003] In the past, the inspection of water tanks in rail transit mainly relied on manual methods. Inspectors had to regularly check each tank one by one. For the water tank's sealing, the method was usually to visually inspect the surface for water stains or to carefully check the connection points for water droplets after the tank was filled with water. However, manual visual inspection of the water tank's sealing is difficult to detect tiny leaks, which can easily lead to the overlooking of potential leakage problems. Current technology has improved the water tank inspection method by introducing an automatic flow regulating valve to achieve precise control of water inlet and outlet. The water level gauge is used to calculate whether the water level in the tank is normal to determine whether the tank is leaking, and it can automatically adjust the flow rate. However, in actual use, when the water tank leaks a little, the water tank will vibrate, making it impossible to accurately calculate the data in the tank, thus failing to detect the problem in time. Furthermore, in the event of a sudden power outage, the existing inspection equipment cannot drain the water in the tank in time. In cold environments, the remaining water in the tank will freeze, causing the tank and internal equipment to freeze and crack, resulting in high maintenance costs and safety hazards for rail transit operations.

[0006] As a further description of the above technical solution:

[0007] The quick-installation mechanism includes two insert plates, which are fixedly connected to the bottom left and right sides of the cover plate, respectively. Each insert plate has an insertion hole on its outer wall. The top left and right sides of the water tank have slots. The two insertion holes are slidably connected to their corresponding slots. Mounting plates are fixedly connected to the left and right sides of the outer wall of the water display cover. Insert rods are slidably connected to the inner walls of the two mounting plates. The adjacent ends of the two insert rods engage with their corresponding insertion holes. Limiting blocks are fixedly connected to the outer walls of the two insert rods. Springs are fixedly connected to the opposite sides of the two limiting blocks. The opposite ends of the two springs are fixedly connected to their respective mounting plates.

[0030] 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.

[0031] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a multifunctional water tank detection device, including a water tank 1 and a cover plate 4. A water indicator 3 is fixedly connected to the outer wall of the water tank 1. The water indicator 3 changes color when it encounters water, thereby determining the location of the leak. A water inlet pipe 5 is connected to the right side of the outer wall of the water tank 1 to introduce external water into the water tank 1, realizing the function of filling the water tank 1 with water. A water outlet pipe 6 is connected to the left side of the outer wall of the water tank 1 to discharge the water in the water tank 1 when needed, facilitating the function of draining the water in the water tank 1. The top right side of the outer wall of the water inlet pipe 5 is connected to... Solenoid valve 7 controls the flow of water through inlet pipe 5. A drain pipe 8 is connected to the bottom rear of water tank 1, responsible for draining water from tank 1 under specific conditions. Solenoid valve 9 is connected to the outer wall of drain pipe 8, automatically opening when power is off, allowing water in tank 1 to drain through drain pipe 8, preventing damage to internal components due to freezing and expansion. A pressure pump 10 is fixedly connected to the right side of the outer wall of water display hood 3, pressurizing water tank 1 through pressure pipe 11. Pressure pipe 11 is connected to the top of pressure pump 10, transmitting the pressure generated by pressure pump 10 to water tank 1. The left end of 11 is connected to the water tank 1, realizing pressure transmission between the pressure pump 10 and the water tank 1. The bottom of the connecting cover plate 4 is fixedly connected to a telescopic rod 12, which drives the water quality detector 13 connected to the bottom to move up and down in the water tank 1. The bottom of the telescopic rod 12 is fixedly connected to the water quality detector 13, which is used to detect the water at different heights in the water tank 1. The top left side of the outer wall of the inlet pipe 5 is connected to a connecting pipe 14, which establishes a connection channel between the flow meter 15 and the inlet pipe 5, so that the flow meter 15 can monitor the water flow in the inlet pipe 5. The top of the connecting pipe 14 A flow meter 15 is fixedly connected to the water tank 1 to monitor the water flow speed in real time. A water level gauge 16 is fixedly connected to the rear side of the inner wall of the water tank 1. A display screen 17 is fixedly connected to the rear side of the top of the cover plate 4 to receive and display the data transmitted by the water quality tester 13 and other testing components. Multiple water level lights 18 are fixedly connected to the front side of the top of the cover plate 4 to intuitively present the water level status through different lighting states, so that the operator can clearly understand the water level status of the water tank 1. A pressure gauge 19 is fixedly connected to the middle of the top of the cover plate 4. A quick-installation mechanism 2 is set at the bottom of the cover plate 4 for quick installation of the cover plate 4.

[0032] Specifically, when the equipment is activated, solenoid valve 7 is turned on, and external water is injected into water tank 1 from inlet pipe 5. During water injection, flow meter 15 is connected to inlet pipe 5 via connecting pipe 14 to monitor water flow speed in real time, providing operators with water injection rate information. At the same time, water level gauge 16 closely monitors water level changes in water tank 1 and displays the water level status visually through water level light 18, making it easy for operators to grasp the water injection progress. When water quality needs to be tested, telescopic rod 12 is operated, which extends from the bottom of cover plate 4, driving water quality detector 13 at the bottom to move up and down in water tank 1 to test water at different heights. Water quality detector 13 transmits the test data to display screen 17 in real time, making it convenient for operators to read and analyze, and to fully understand the water quality in water tank 1. To test the pressure resistance of water tank 1, pressure pump 1 is started. 0. The pressure pump 10 is located on the right side of the outer wall of the water indicator hood 3. It pressurizes the water tank 1 through the pressure pipe 11. At this time, the pressure gauge 19 is fixed at the top center of the cover plate 4 and displays the pressure value inside the water tank 1 in real time. This helps the operator to judge whether the pressure bearing performance of the water tank 1 meets the standard. During normal use, the water in the water tank 1 can be discharged through the outlet pipe 6 as needed. When the equipment encounters a power failure, the solenoid valve 2 9 plays a key role. Due to its special design, it opens automatically when the power is off. The drain pipe 8 connected to the bottom rear side of the water tank 1 opens the drainage channel, allowing the water in the water tank 1 to be drained quickly. This effectively prevents the equipment from freezing and cracking due to the expansion of water. In addition, the water indicator hood 3 on the outer wall of the water tank 1 will change color once it comes into contact with water when the water tank 1 leaks. This accurately indicates the location of the leak and facilitates timely maintenance.

[0033] Reference Figure 1 , Figure 2 and Figure 4 The quick-installation mechanism 2 includes two insert plates 201, which are fixedly connected to the bottom left and right sides of the cover plate 4, respectively, providing a positioning base for subsequent connection. Insert holes 202 on the outer wall of the insert plates 201 are used to cooperate with the insert rod 205, enhancing the connection stability. The slots 203 on the top left and right sides of the water tank 1 are slidably connected to the insert holes 202 on the insert plates 201, guiding the insert plates 201 to accurately slide down to the predetermined position. The mounting plates 204 on the left and right sides of the outer wall of the water display cover 3 provide installation and sliding space for the insert rod 205. The insert rod 205, slidably connected to the inner wall of the mounting plate 204, is located on the insert plate 201. When 01 is in place, its adjacent end engages with the corresponding insertion hole 202 to achieve quick connection. The limiting block 206 on the outer wall of the insertion rod 205 restricts the movement range of the insertion rod 205 to ensure accurate engagement. The spring 207 connected to the side away from the limiting block 206 stores energy when the insertion plate 201 is pressed down and releases energy when the insertion hole 202 is aligned with the insertion rod 205, pushing the insertion rod 205 into the insertion hole 202 to complete quick installation. The other end of the spring 207 is fixed to the mounting plate 204 to ensure stable operation of the spring 207. The overall quick-installation mechanism 2 greatly improves the installation and disassembly efficiency of the cover plate 4 and the water tank 1.

[0034] Specifically, when installing the cover plate 4, lift the cover plate 4 so that the insert plates 201 fixed on the left and right sides of the bottom are aligned with the slots 203 opened on the left and right sides of the top of the water tank 1. As the cover plate 4 moves downward, the insert plates 201 slide down along the slots 203. During this process, the insertion holes 202 on the outer wall of the insert plates 201 descend synchronously. Since the mounting plates 204 are fixedly connected to the left and right sides of the outer wall of the water display cover 3, and the insert rods 205 are slidably connected to the inner wall of the mounting plates 204, the insert plates 201 will first squeeze the insert rods 205 when descending. After the insert rods 205 are subjected to force, they will drive the limiting blocks 206 fixed on the outer wall to move together, thereby squeezing the spring 207 connected to the side of the limiting block 206 away from the insertion holes 202. At this time, the spring 207... 07. The spring 207 compresses and stores elastic potential energy. When the insert plate 201 continues to descend until the insertion hole 202 moves to the position aligned with the insert rod 205, the compressed spring 207 generates elastic force to restore its deformation, pushing the limit block 206, which in turn drives the insert rod 205 to quickly insert into the corresponding insertion hole 202, achieving a tight engagement between the insert rod 205 and the insertion hole 202, completing the rapid installation of the cover plate 4 and the water tank 1, ensuring a stable connection. When disassembling the cover plate 4, the operation is reversed, and external force is applied to overcome the elastic force of the spring 207, pulling the insert rod 205 out of the insertion hole 202, releasing the engagement state between the two. Then, the cover plate 4 can be easily lifted upwards, causing the insert plate 201 to disengage from the slot 203, completing the disassembly process.

[0035] Reference Figure 1 , Figure 4 and Figure 5 A sealing ring 20 is fixedly connected to the top of the water tank 1. Both insert plates 201 pass through the sealing ring 20. When the two insert plates 201 pass through, the sealing ring 20 can fit tightly against the insert plates 201, preventing water in the water tank 1 from leaking out from the connection between the cover plate 4 and the water tank 1, thus achieving a good sealing effect. An information board 21 is set on the front side of the outer wall of the water display cover 3. Screws 22 are threadedly connected to the four corners of the outer wall of the information board 21. The rear ends of the screws 22 pass through the water display cover 3 and are threadedly connected to the water tank 1. The information board 21 is firmly fixed to the water display cover 3 through the screws 22 threaded at the four corners of its outer wall and the rear ends of the screws 22 pass through the water display cover 3 and are threadedly connected to the water tank 1, thus displaying relevant equipment information. Support legs 23 are fixedly connected to the four corners of the bottom of the water tank 1. Bolts 24 are threadedly connected to the middle of the support legs 23. Rotating the bolts 24 can adjust the height of the support legs 23, so that the water tank 1 can remain stable on uneven ground.

[0036] Specifically, the sealing ring 20 fixedly connected to the top of the water tank 1 can tightly fit the insert plate 201 when the two insert plates 201 pass through, preventing water in the water tank 1 from leaking out from the connection between the cover plate 4 and the water tank 1, thus playing a good sealing role and ensuring the normal operation of the water tank 1. The information plate 21 set on the front side of the outer wall of the water display cover 3 is fixedly fixed to the water display cover 3 by screws 22 threaded at the four corners of its outer wall. The rear ends of the screws 22 pass through the water display cover 3 and are threadedly connected to the water tank 1, thereby displaying relevant equipment information. Support legs 23 are fixedly connected to the four corners of the bottom of the water tank 1. Bolts 24 are threadedly connected to the middle of the multiple support legs 23. Rotating the bolts 24 can adjust the height of the support legs 23, so that the water tank 1 can remain stable on uneven ground.

[0037] Reference Figure 1 , Figure 2 and Figure 4 Each of the two insertion rods 205 has a pull ring 25 slidably connected to its far end. The surfaces of both pull rings 25 are treated with anti-slip material to facilitate the operation of the operator to slide the insertion rods 205 through the pull rings 25 to install and remove the cover plate 4. A controller 26 is fixedly connected to the right side of the outer wall of the water display cover 3. The controller 26 is electrically connected to solenoid valve 7 and solenoid valve 9 respectively, and plays the role of controlling the water flow in and out. Multiple control buttons 27 are fixedly connected to the top right side of the cover plate 4. The multiple control buttons 27 are electrically connected to the controller 26. The operator can send commands to the controller 26 through the control buttons 27.

[0038] Specifically, the pull ring 25, which is slidably connected to the two insert rods 205 at opposite ends, has an anti-slip surface to facilitate the operator to slide the insert rods 205 through the pull ring 25 to install and remove the cover plate 4. The controller 26, which is fixed on the right side of the outer wall of the water display cover 3, is electrically connected to the solenoid valve 7 and the solenoid valve 9 respectively, and plays the role of controlling the water flow in and out. The multiple control buttons 27, which are fixed on the top right side of the cover plate 4, are electrically connected to the controller 26, and the operator can send commands to the controller 26 through the control buttons 27.

[0039] Working principle: When solenoid valve 7 is opened, external water is injected into water tank 1 through inlet pipe 5. During water injection, flow meter 15 is connected to inlet pipe 5 via connecting pipe 14 to monitor water flow speed and transmit water injection rate information to the operator. At the same time, water level gauge 16 monitors water level changes in water tank 1 and displays the water level status through water level light 18, allowing the operator to monitor the water injection progress. When water quality needs to be tested, the operator operates telescopic rod 12, which extends from the bottom of cover plate 4, driving water quality detector 13 to move up and down inside water tank 1 to detect water at different heights. Water quality detector 13 transmits the test data to display screen 17 for the operator to understand the water quality. To test the water quality inside tank 1 and its pressure-bearing capacity, the pressure pump 10 on the right side of the outer wall of the water indicator hood 3 is started. The pressure pump 10 applies pressure to the water tank 1 through the pressure pipe 11. At this time, the pressure gauge 19 at the top center of the cover plate 4 displays the internal pressure value of the water tank 1, helping the operator to judge the pressure-bearing performance of the water tank 1. During normal use, water can be drained through the outlet pipe 6 as needed. When the equipment is powered off, the solenoid valve 2 9 opens automatically, and the drain pipe 8 connected to the bottom rear side of the water tank 1 opens the drainage channel to drain the water in the water tank 1, preventing the equipment from being damaged by the expansion of water freezing. In addition, the water indicator hood 3 on the outer wall of the water tank 1 changes color when there is a leak, indicating the location of the leak, which is convenient for maintenance personnel to handle.

[0040] Furthermore, when installing the cover plate 4, lift the cover plate 4 so that the bottom insert plate 201 is aligned with the top slot 203 of the water tank 1. Then, the cover plate 4 moves downward, and the insert plate 201 slides down along the slot 203. The insertion hole 202 on the outer wall of the insert plate 201 descends simultaneously. Because the insert rod 205 is connected to the mounting plate 204 on the outer wall of the water display cover 3, the descending insert plate 201 squeezes the insert rod 205. The insert rod 205 drives the limit block 206 to move, compressing the spring 207 to store energy. The insert plate 201 continues to descend. When the insertion hole 202 is aligned with the insert rod 205, the spring 207 restores its deformation and generates elastic force, pushing the limit block 206 and driving the insert rod 205 to insert into the insertion hole 202, thus completing the quick installation of the cover plate 4 and the water tank 1. The connection is stable. To remove the cover plate 4, reverse the operation, apply force to overcome the elastic force of the spring 207, pull out the insert rod 205 to release the lock, lift the cover plate 4, and let the insert plate 201 disengage from the slot 203 to complete the disassembly. The operation is simple and convenient.

[0041] 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.
