Description

Technical Field

[0001] The utility model relates to the technical field of adding medicine to cooling water in a machine room, in particular to an automatic monitoring and adding device for the water quality of circulating water in a machine room. Background Art

[0002] Circulating water systems play a crucial role in cooling equipment rooms (especially data centers and communication base stations). They dissipate the enormous heat generated by IT equipment. Maintaining stable circulating water quality is key to ensuring efficient, safe, and long-term system operation. Deteriorating water quality (such as scaling, corrosion, and microbial growth) can significantly reduce heat exchange efficiency, clog pipes, corrode equipment, and even cause system failures and downtime, resulting in significant economic losses.

[0003] Currently, the water quality management of the computer room's circulating water system mainly relies on manual regular sampling and testing and manual dosing and adjustment. This approach has obvious drawbacks:

[0004] 1. Lag: The frequency of manual testing is limited, making it difficult to detect abnormal fluctuations in water quality parameters in a timely manner, resulting in delayed dosing timing;

[0005] 2. Uneven mixing of dosing: In the traditional continuous or simple injection dosing method, the diffusion speed of the agent is slow after entering the main pipeline, especially in low flow rate or large diameter sections, which can easily lead to local concentrations that are too high or too low, affecting the treatment effect and agent utilization rate.

[0006] Therefore, it is necessary to provide a new automatic monitoring and dosing device for circulating water quality in a machine room to solve the above technical problems. Utility Model Content

[0007] In order to solve the above technical problems, the utility model provides a device for automatically monitoring and dosing the circulating water quality in a machine room.

[0008] The automatic monitoring and dosing device for circulating water quality in a machine room provided by the utility model comprises a central connecting pipe, both ends of which are equipped with docking flanges, and a plurality of equally spaced side holes are opened on the central connecting pipe, and a dosing pipe is fixedly welded to each of the side holes;

[0009] The central link pipe is provided with a detection component for monitoring the water flowing through the central link pipe;

[0010] An intermittent dosing device is installed in the dosing tube, and the intermittent dosing device includes a fixed disk, the fixed disk is fixedly installed in the dosing tube, and a plurality of fan-shaped diversion holes are opened on the fixed disk, and a rotating disk rotatably connected is installed on the disk surface of the fixed disk close to the central connecting tube, and the rotating disk is provided with docking holes corresponding to the diversion holes;

[0011] A rotating rod is fixedly mounted on the rotating disk, and the other end of the rotating rod extends into the central connecting pipe and is fixedly mounted with a plurality of blades distributed in an annular shape.

[0012] Preferably, a fixing ring is fixedly installed on the disk surface of the fixed disk close to the central connecting pipe, and the inner ring surface of the fixing ring is provided with a T-shaped ring groove with a T-shaped cross-section. The rotating disk is inserted into the fixing ring, and a T-shaped ring with a T-shaped cross-section is fixedly installed on the outer ring wall of the rotating disk. The T-shaped ring is inserted into the T-shaped ring groove and is rotatably connected to the T-shaped ring groove.

[0013] Preferably, a rotating bracket is fixedly installed at the pipe head of the dosing pipe close to the central connecting pipe, and the rotating rod passes through the through hole provided in the rotating bracket and is rotatably connected to the rotating bracket.

[0014] Preferably, the detection component includes an arc-shaped plate, and the arc-shaped plate is fixedly installed in the installation cavity opened in the central connecting pipe, the inner plate wall of the arc-shaped plate is installed with a sensor module through a hanging bracket, and the outer plate surface of the arc-shaped plate is fixedly installed with a controller electrically connected to the sensor module.

[0015] Preferably, a connecting flange is fixedly installed on the pipe head of the dosing pipe, and a control valve is installed on the dosing pipe between the connecting flange and the fixed plate.

[0016] Preferably, an annular groove coaxially arranged with the central connecting pipe is provided on the docking flange, and a filter disc is fixedly installed in the annular groove by a screw.

[0017] Preferably, the detection component is close to one side of the water inlet of the central connecting pipe.

[0018] Compared with related technologies, the automatic monitoring and dosing device for circulating water quality in a machine room provided by the present invention has the following beneficial effects:

[0019] When the utility model adds medicine to the central link pipe, the control valve of the medicine-adding pipe for adding the corresponding medicine is opened, and the booster pump in the medicine storage tank is turned on at the same time, so that the medicine in the medicine storage tank can enter the medicine-adding pipe. Since the circulating water in the machine room can drive the blades to rotate when passing through the central link pipe, the rotating rod drives the rotating disk to rotate, so that the docking holes on the rotating disk and the diversion holes on the fixed disk are continuously connected and closed in a dynamic conversion (a flow channel is formed when the holes are aligned, and is closed when they are misaligned), thereby realizing the intermittent flow of the medicine into the central link pipe and avoiding the problem of excessively high local concentration near the dosing point and insufficient concentration at the far end which may be caused by continuous dosing. The rotating blades can also mix the added medicine with the water liquid, greatly improving the treatment effect of the medicine on the water quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0031] See also Figures 1 to 8The embodiment of the present invention provides an automatic monitoring and dosing device for circulating water quality in a computer room. The automatic monitoring and dosing device for circulating water quality in a computer room includes a central connecting pipe 1, a detection component 2, a dosing pipe 3 and an intermittent dosing component 4.

[0032] In the embodiments of the present invention, please refer to Figures 1 to 8 Both ends of the central connecting pipe 1 are equipped with docking flanges 11, and a plurality of equally spaced side holes 1a are opened on the central connecting pipe 1. A dosing pipe 3 is fixedly welded to each side hole 1a, and a connecting flange 31 is fixedly installed on the pipe head of the dosing pipe 3, and a control valve 32 is installed on the dosing pipe 3 between the connecting flange 31 and the fixed plate 41.

[0033] When installing this application in the machine room, a section of the machine room circulating water pipeline is cut in advance, and then flanges are installed at both ends of the pipe cut head. At the same time, valves (such as butterfly valves and solenoid valves) are installed on the docking flanges 11 at both ends of the central pipe 1. The valves at both ends of the central pipe 1 are then installed to the cut-off part of the machine room circulating water pipeline, and the flanges on the valves are fixedly connected to the flanges on the pipe cut head. Each dosing pipe 3 is connected to the liquid outlet of the corresponding medicine storage tank, and a booster pump is set in the medicine storage tank so that the medicine can be added from the dosing pipe 3 to the central pipe 1. Before dosing, the control valve 32 on the dosing pipe 3 is closed to prevent the water in the machine room circulating water pipeline from flowing into the medicine storage tank.

[0034] In the embodiments of the present invention, please refer to Figures 1 to 8 A detection component 2 for monitoring the water flowing through the central pipe 1 is installed on the central pipe 1, and the detection component 2 includes an arc-shaped plate 21, and the arc-shaped plate 21 is fixedly installed in the installation cavity 1b opened in the central pipe 1. The inner wall of the arc-shaped plate 21 is installed with a sensor module 24 through a hanging bracket 23, and the outer surface of the arc-shaped plate 21 is fixedly installed with a controller 22 electrically connected to the sensor module 24. The controller 22 is electrically connected to the computer room control terminal, and the detection component 2 is close to the side of the water inlet of the central pipe 1.

[0035] It should be noted that the sensor module 24 of the present application can be any combination of a pH sensor, a turbidity sensor, an ORP sensor, a residual chlorine sensor and a conductivity sensor. After the sensor module 24 detects the water quality, the controller 22 transmits the detected information to the computer room control terminal. Subsequently, the staff uses the corresponding dosing pipe 3 to perform targeted dosing on the computer room circulating water pipeline based on the detected water quality information.

[0036] Among them, an annular groove 11a is provided on the docking flange 11, which is coaxially arranged with the central connecting pipe 1, and a filter disc 5 is fixedly installed in the annular groove 11a by a screw. The filter disc 5 can filter the water quality, avoiding the hidden danger of solid particles adhering to the sensor module 24, causing inaccurate detection by the sensor module 24. When cleaning or replacing the filter disc 5, close the valves at both ends of the central connecting pipe 1, then remove the central connecting pipe 1 from the valve, remove the filter disc 5 and replace it with a new one.

[0037] In the embodiments of the present invention, please refer to Figures 1 to 8 An intermittent dosing member 4 is installed in the dosing tube 3, and the intermittent dosing member 4 includes a fixed disk 41, which is fixedly installed in the dosing tube 3, and a plurality of guide holes 41a distributed in a fan shape are opened on the fixed disk 41. A rotating disk 42 is rotatably connected to the disk surface of the fixed disk 41 close to the central link tube 1, and a docking hole 42a corresponding to the guide hole 41a is opened on the rotating disk 42. A rotating rod 43 is fixedly installed on the rotating disk 42, and the other end of the rotating rod 43 extends into the central link tube 1 and is fixedly installed with a plurality of blades 44 distributed in an annular shape.

[0038] It should be noted that: when adding medicine to the central link pipe 1, the control valve 32 of the dosing pipe 3 for adding the corresponding medicine is opened, and the booster pump in the medicine storage tank is turned on at the same time, so that the medicine in the medicine storage tank can enter the dosing pipe 3. Since the circulating water in the machine room can drive the blades 44 to rotate when passing through the central link pipe 1, the rotating rod 43 drives the rotating disk 42 to rotate, so that the docking hole 42a on the rotating disk 42 and the guide hole 41a on the fixed disk 41 are continuously connected and closed dynamically (a flow channel is formed when the holes are aligned, and closed when they are misaligned), thereby realizing intermittent flow of the medicine into the central link pipe 1 and avoiding the problem of excessive local concentration near the dosing point and insufficient concentration at the far end due to continuous dosing. The rotating blades 44 can also stir the added medicine and the water, greatly improving the treatment effect of the medicine on water quality.

[0039] In this embodiment: a fixing ring 411 is fixedly installed on the disk surface of the fixed disk 41 close to the central connecting pipe 1, and the inner ring surface of the fixing ring 411 is provided with a T-shaped ring groove with a T-shaped cross section. The rotating disk 42 is inserted into the fixing ring 411, and a T-shaped ring with a T-shaped cross section is fixedly installed on the outer ring wall of the rotating disk 42. The T-shaped ring is inserted into the T-shaped ring groove and is rotatably connected to the T-shaped ring groove, thereby realizing the rotational connection between the rotating disk 42 and the fixed disk 41. In order to avoid surface liquid leakage, a sealing ring is provided between the fixed disk 41 and the rotating disk 42.

[0040] Furthermore, a rotating bracket 45 is fixedly installed at the pipe head of the dosing pipe 3 near the central connecting pipe 1, and the rotating rod 43 passes through the through hole opened in the rotating bracket 45 and is rotatably connected to the rotating bracket 45, thereby preventing the rotating rod 43 from swinging too much near the end of the blade 44 when the blade 44 drives the rotating rod 43 to rotate under the drive of water.

[0041] The present application utilizes the energy of the circulating water flow itself to drive the blades 44 to rotate, thereby driving the rotating rod 43 and the rotating disk 42 to rotate synchronously. The docking hole 42a on the rotating disk 42 and the guide hole 41a on the fixed disk 41 are periodically aligned and staggered during the rotation process. When the guide hole 41a is aligned with the docking hole 42a, a medicine flow channel is formed; when they are staggered, the flow channel is closed. This periodic opening and closing allows the medicine to be injected into the main water flow of the central link pipe 1 in a pulsed (intermittent) manner rather than a continuous manner. Each pulse injection is equivalent to creating a local, high-concentration medicine "liquid mass" in the main pipe water flow. After the "liquid mass" enters the central link pipe 1, it is subjected to the strong shear and impact of the subsequent high-speed water flow, making it easier to break and diffuse rapidly, forming strong turbulence, which greatly accelerates the mixing process of the medicine with the water flow of the entire cross-section of the central link pipe 1, and avoids the problem of excessive local concentration near the dosing point (which may cause side effects or waste) and insufficient concentration at the distal end due to continuous dosing.

[0042] Among them, the circulating water system in this application maintains its flow rate to drive the blades 44 to rotate. In order to cope with the problem that the water flow power may not be sufficient to drive the blades 44 to rotate effectively, a flow rate sensor is added to the central pipe 1 and a booster pump is installed. When the flow rate sensor detects that the water speed is too low, the booster pump on the central pipe 1 is started to increase the water flow through the central pipe 1.

[0043] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.
