Description

Technical Field

[0001] The utility model relates to the technical field of industrial cooling, in particular to a novel cooling water pipe. Background Art

[0002] In the cooling and air-conditioning system, the Y-type filter of the cooling water pump is a key component. It is essential to protect the normal operation of the entire cooling system. The Y-type filter is usually installed at the inlet of the cooling water pump. Its main function is to filter impurities and particulate matter in the cooling water entering the water pump. These impurities may include scale, rust, fiber, etc. If they enter the water pump and cooling system, it may cause pipe blockage, increased equipment wear, reduced cooling efficiency and even system failure. By installing a Y-type filter, these impurities can be effectively intercepted to ensure the cleanliness of the cooling water, thereby extending the service life of the system and improving operating efficiency.

[0003] The Y-type filter is an indispensable component in the cooling system. Its main function is to intercept and remove impurities in the cooling water to ensure the smooth operation of the system. However, over time, more impurities may accumulate inside the filter, which will affect its filtering effect. In order to timely monitor and clean the debris inside the filter, the common method is to judge by measuring the temperature difference before and after the cooling water is used. When the temperature difference is small, this may mean that the Y-type filter is at risk of clogging. However, relying solely on temperature difference monitoring cannot determine whether the Y-type filter is clogged, because other factors, such as the working status of the cooling tower, may also affect the temperature. The traditional method of elimination is used to check the problem of poor cooling effect of the cooling water pipe, which will affect the efficiency of the maintenance operation. At this time, it is necessary to improve the blockage monitoring method of the Y-type filter in the cooling water pipe to improve the maintenance efficiency. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a new cooling water pipe to solve the technical problem that the traditional method of eliminating the cooling effect of the cooling water pipe is used to check for poor cooling effect, thereby reducing the efficiency of maintenance operations.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new cooling water pipe, comprising a water inlet pipe and a water outlet pipe, wherein a Y-type filter is connected between the water inlet pipe and the water outlet pipe via a flange, and a monitoring mechanism is arranged inside the water inlet pipe, wherein the monitoring mechanism is used to monitor the flow rate of cooling water inside the water inlet pipe, and use the flow rate data to judge the blockage condition of the Y-type filter.

[0006] By adopting the above technical solution, the internal cooling water vortex impacts the inner wall of the water inlet pipe. The intensity of this impact is directly related to the flow rate of the cooling water. When the cooling water flow rate inside the water inlet pipe increases, the impact of the vortex on the pipe wall also increases.

[0007] Furthermore, the monitoring mechanism includes a vibration plate, and both upper and lower ends of the vibration plate are fixedly connected to the inner wall of the water inlet pipe through a connecting rod.

[0008] By adopting the above technical solution, this fixed structure enables the vibrating plate to be stably placed in the cooling water flow, thereby accurately sensing the dynamic changes of the water flow.

[0009] Furthermore, the vibration plate has a rectangular structure and is arranged parallel to the flow direction of the cooling water inside the water inlet pipe.

[0010] By adopting the above technical solution, the rectangular structure enables the vibrating plate to have a larger contact area in the water flow, so that the flow rate change of the cooling water can be sensed more comprehensively.

[0011] Furthermore, first vibration sensors are provided on both sides of the water inlet pipe, and the first vibration sensors are electrically connected to an external power supply through a control center.

[0012] By adopting the above technical solution, the first vibration sensors on both sides of the water inlet pipe can fully monitor the eddy current impact on the pipe wall when the cooling water flows inside the water inlet pipe.

[0013] Furthermore, the first vibration sensor is used to monitor the impact vibration force of the vortex inside the water inlet pipe on the inner wall of the water inlet pipe.

[0014] By adopting the above technical solution, the first vibration sensor can monitor in real time the impact vibration force of the vortex inside the water inlet pipe on the inner wall of the water inlet pipe. This monitoring can directly reflect the changes in the cooling water flow rate and possible blockages.

[0015] Furthermore, the connecting rod is rotatably connected to the inner wall of the water inlet pipe via a bearing, and the bearing is a sealed bearing.

[0016] By adopting the above technical solution, the rotational connection between the connecting rod and the water inlet pipe enables the vibration plate to more flexibly adapt to changes in the cooling water flow rate, thereby more accurately sensing and transmitting dynamic information of the water flow.

[0017] Furthermore, one end of the connecting rod passes through the outer wall of the water inlet pipe and is fixedly connected to a mounting seat, on which a second vibration sensor is installed.

[0018] By adopting the above technical solution, this structure enables the second vibration sensor to be stably installed outside the water inlet pipe, which is convenient for monitoring the vibration caused by the flow of cooling water.

[0019] Furthermore, the second vibration sensor is used to monitor the vibration frequency of the vibration plate.

[0020] By adopting the above technical solution, the second vibration sensor can monitor the vibration frequency of the vibration plate in real time. This monitoring provides direct data support for determining the cooling water flow rate.

[0021] Furthermore, a filter screen is arranged inside the Y-type filter, and the filter screen is detachable from the Y-type filter through a blind plate.

[0022] By adopting the above technical solution, the filter can effectively filter impurities and scale in the cooling water, maintain the cleanliness of the cooling water, and prevent these debris from entering the cooling system to cause blockage or damage.

[0023] In summary, the utility model mainly has the following beneficial effects:

[0024] 1. The utility model uses the first vibration sensors on both sides of the water inlet pipe to monitor the impact vibration data of the cooling water vortex on the inner wall of the water inlet pipe through the monitoring mechanism. When the cooling water flow rate inside the water inlet pipe increases, the force of the vortex impacting the pipe wall also increases. This impact force is directly reflected in the monitoring value of the sensor. At the same time, according to the data collected by the first vibration sensor, the flow rate of the cooling water inside the water inlet pipe can be accurately calculated. When the flow rate is reduced to a preset specified value, it indicates that a lot of debris may have accumulated inside the Y-type filter, affecting the normal passage of water. Therefore, the system will issue a cleaning reminder in time, prompting the staff to perform necessary inspections and cleaning work on the Y-type filter, thereby improving the inspection efficiency and maintenance level of the cooling system;

[0025] 2. The utility model sets a second vibration sensor. When the cooling water inside the water inlet pipe flows through the vibration plate, the vibration plate will be in a vibrating state through the principle of vortex-induced vibration of liquid fluid. This vibration state can directly reflect the change of cooling water flow rate and provide accurate signals for monitoring. At the same time, the bearing is used to make the vibration plate and the connecting rod form a rotatable structure, which ensures that the vibration plate can flexibly respond to the dynamic changes of water flow. When the vibration data is collected by the second vibration sensor on the mounting base, the change of vibration frequency can be monitored in real time. When the vibration frequency is reduced to a certain value, it indicates that a lot of debris may be accumulated inside the Y-type filter, resulting in water flow obstruction. This monitoring method helps to detect filter blockage in time and remind staff to clean it, thereby ensuring the normal operation of the cooling system. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0032] The following describes an embodiment of the utility model based on its overall structure.

[0033] Embodiment 1:

[0034] A new type of cooling water pipe, such as Figure 1-Figure 4 As shown, it includes an inlet pipe 1 and an outlet pipe 2, and a Y-type filter 3 is connected between the inlet pipe 1 and the outlet pipe 2 through a flange. A monitoring mechanism 5 is arranged inside the inlet pipe 1, and the monitoring mechanism 5 is used to monitor the flow rate of cooling water inside the inlet pipe 1, and use the flow rate data to determine the blockage of the Y-type filter 3. The internal cooling water vortex impacts the inner wall of the inlet pipe 1, and the intensity of this impact is directly related to the flow rate of cooling water. When the flow rate of cooling water inside the inlet pipe 1 increases, the impact degree of the vortex on the pipe wall also increases accordingly. At the same time, the first vibration sensor 503 on both sides of the inlet pipe 1 can monitor the vibration data caused by this impact in real time. By analyzing these data, we can accurately obtain the flow rate of cooling water inside the inlet pipe 1. When the flow rate drops to a specified value, it means that a lot of debris may be accumulated inside the Y-type filter 3, resulting in water flow obstruction. At this time, the system will remind the staff to clean up the debris from the Y-type filter 3 in time, thereby improving the maintenance efficiency of the cooling system. This monitoring method is simple and direct, which helps to ensure the stable operation of the cooling system.

[0035] See also Figure 1 , Figure 2The monitoring mechanism 5 includes a vibration plate 501, and the upper and lower ends of the vibration plate 501 are fixedly connected to the inner wall of the water inlet pipe 1 through a connecting rod 502. This fixed structure enables the vibration plate 501 to be stably placed in the cooling water flow, so as to accurately sense the dynamic changes of the water flow. At the same time, due to the fixed connection between the vibration plate 501 and the inner wall of the water inlet pipe 1, when the cooling water flows through the vibration plate 501, the impact force generated by the water flow on the vibration plate 501 can be directly transmitted to the connecting rod 502 and the inner wall of the water inlet pipe 1. This transmission method enables the first vibration sensor 503 to more accurately monitor the vibration data changes caused by the cooling water flow rate, thereby providing a reliable basis for judging the blockage condition of the Y-type filter 3.

[0036] See also Figure 1 , Figure 2 The vibration plate 501 has a rectangular structure and is arranged parallel to the flow direction of the cooling water in the water inlet pipe 1. The rectangular structure allows the vibration plate 501 to have a larger contact area in the water flow, so that the flow rate change of the cooling water can be more comprehensively sensed. At the same time, the vibration plate 501 is arranged parallel to the flow direction of the cooling water in the water inlet pipe 1, which ensures that the cooling water can flow smoothly through the vibration plate 501, so that the vibration plate 501 can respond to the change of the water flow rate more accurately. This arrangement improves the accuracy and stability of flow rate monitoring, helps to timely detect the blockage of the Y-type filter 3, and ensures the normal operation of the cooling system.

[0037] See also Figure 1 , Figure 2 A first vibration sensor 503 is provided on both sides of the water inlet pipe 1. The first vibration sensor 503 is electrically connected to the external power supply through the control center. The first vibration sensors 503 on both sides of the water inlet pipe 1 can comprehensively monitor the eddy current impact on the pipe wall when the cooling water flows inside the water inlet pipe 1. At the same time, the stable power supply of the sensor and the real-time transmission of data are ensured, so that the sensor can continuously and accurately monitor the changes in the cooling water flow rate, which provides an important basis for judging the blockage condition of the Y-type filter 3 and helps to improve the operation efficiency and maintenance efficiency of the cooling system.

[0038] See also Figure 1 , Figure 2 The first vibration sensor 503 is used to monitor the impact vibration force of the internal vortex of the water inlet pipe 1 on the inner wall of the water inlet pipe 1. The first vibration sensor 503 can monitor the impact vibration force of the internal vortex of the water inlet pipe 1 on the inner wall of the water inlet pipe 1 in real time. This monitoring can directly reflect the changes in the cooling water flow rate and possible blockages. At the same time, by monitoring the impact vibration force, the first vibration sensor 503 provides accurate data support for determining whether the Y-type filter 3 needs to be cleaned. This real-time monitoring helps to promptly discover and deal with problems in the cooling system to ensure stable operation and efficient performance of the system.

[0039] Embodiment 2:

[0040] See also Figure 3 , Figure 4 The connecting rod 502 is rotatably connected to the inner wall of the water inlet pipe 1 through a bearing 504. The bearing 504 is a sealed bearing. The rotatable connection between the connecting rod 502 and the water inlet pipe 1 enables the vibrating plate 501 to more flexibly adapt to changes in the cooling water flow rate, thereby more accurately sensing and transmitting dynamic information of the water flow. At the same time, the bearing 504 adopts a sealed structure, which can effectively prevent cooling water and other impurities from entering the bearing, ensuring the normal operation of the bearing and the stable rotation of the connecting rod 502. This sealing structure improves the reliability and durability of the entire monitoring mechanism 5, and helps to extend the service life of the cooling system.

[0041] See also Figure 3 , Figure 4 One end of the connecting rod 502 passes through the outer wall of the water inlet pipe 1 and is fixedly connected to a mounting base 505, on which a second vibration sensor 506 is installed. This structure enables the second vibration sensor 506 to be firmly installed on the outside of the water inlet pipe 1, so as to monitor the vibration caused by the flow of cooling water. At the same time, by installing the second vibration sensor 506 on the mounting base 505, the accuracy and reliability of monitoring the cooling water flow rate can be further increased. The second vibration sensor 506 can monitor the vibration signal transmitted by the vibration plate 501 and the connecting rod 502 in real time, thereby providing additional data support, helping to more comprehensively understand the operating status of the cooling system, and helping to improve the maintenance efficiency and operating stability of the cooling system.

[0042] See also Figure 3 , Figure 4 The second vibration sensor 506 is used to monitor the vibration frequency of the vibration plate 501. The second vibration sensor 506 can monitor the vibration frequency of the vibration plate 501 in real time. This monitoring provides direct data support for determining the cooling water flow rate. At the same time, by monitoring the vibration frequency of the vibration plate 501, the second vibration sensor 506 helps to timely detect changes in the cooling water flow rate, and then determine whether the Y-type filter 3 is blocked, thereby ensuring the stable operation of the cooling system. This real-time monitoring helps to improve the maintenance efficiency and operational reliability of the cooling system.

[0043] See also Figure 1 , Figure 2 , Figure 3A filter screen 4 is arranged inside the Y-type filter 3, and the filter screen 4 is detachable with the Y-type filter 3 through a blind plate. The filter screen 4 can effectively filter impurities and scale in the cooling water, maintain the cleanliness of the cooling water, and prevent these sundries from entering the cooling system to cause blockage or damage. At the same time, the filter screen 4 is a detachable structure, which is convenient for the staff to regularly disassemble the filter screen 4 for cleaning or replacement, which is convenient for maintenance and improves the service life and maintenance efficiency of the cooling system.

[0044] The implementation principle of the utility model is:

[0045] Embodiment 1: First, cooling water flows through the water inlet pipe 1, the Y-type filter 3 and the water outlet pipe 2 in sequence. The Y-type filter 3 is used to screen out impurities and scale inside the cooling water to prevent these impurities from entering the cooling system. When the cooling water flows inside the water inlet pipe 1, the cooling water body impacts the vibration plate 501 and is divided into two parts of water by the vibration plate 501, and at the same time, a liquid fluid vortex-induced vibration is formed, and the internal cooling water vortex impacts the inner wall of the water inlet pipe 1. At this time, the first vibration sensor 503 on both sides of the water inlet pipe 1 is used to The vibration data of the outer wall impacted by the cooling water is monitored. The greater the cooling water flow rate inside the water inlet pipe 1, the greater the eddy current impact on the wall of the water inlet pipe 1, and the value monitored by the first vibration sensor 503 will also change accordingly. The flow rate of the cooling water inside the water inlet pipe 1 is obtained through the monitoring data of the first vibration sensor 503. When the flow rate drops to a specified value, it can be determined that there are relatively many debris inside the Y-type filter 3, and the staff is reminded to clean the debris from the Y-type filter 3 in time, which is conducive to improving the maintenance efficiency of the cooling system;

[0046] Embodiment 2: The cooling water inside the water inlet pipe 1 flows through the vibration plate 501, and the vibration plate 501 is in a vibrating state through the principle of vortex-induced vibration of liquid fluid. At the same time, the bearing 504 is used to make the vibration plate 501 and the connecting rod 502 rotatable until the vibration data is collected by the second vibration sensor 506 on the mounting seat 505. When the cooling water flow rate inside the water inlet pipe 1 is large, the vibration frequency of the vibration plate 501 is large, and the data monitored by the second vibration sensor 506 changes with the flow rate of the internal cooling water. When the vibration frequency is reduced to a certain value, it can be judged that there are relatively more debris inside the Y-type filter 3, and the staff is reminded to clean up the debris from the Y-type filter 3 in time;

[0047] Vortex-induced vibration of liquid fluid is a fluid mechanics phenomenon that occurs when a liquid flows through a certain geometric shape. When the liquid flows through the shape, rotating vortices are formed. These vortices interact with the shape, causing the shape to vibrate. Simply put, vortex-induced vibration is the vibration phenomenon of an object caused by the interaction between the vortices formed when the liquid passes through a certain obstacle and the obstacle.
