Description

Technical Field

[0001] This utility model relates to the technical field of water sample collection devices, and in particular to a water sample collection structure for a cooling tower sewage pipe. Background Technology

[0002] Cooling towers are widely used in industrial production processes to cool circulating water. During the operation of cooling towers, sewage pipes discharge wastewater containing various impurities, microorganisms, and chemical substances. In order to monitor the water quality of the wastewater from cooling towers, it is necessary to collect and test water samples from the sewage pipes regularly.

[0003] Currently, most existing water sampling methods involve setting up sampling ports directly on sewage pipes and manually opening the valves at these ports to collect water samples. However, this method has certain drawbacks. When collecting water samples manually, the unstable water pressure inside the sewage pipes can easily cause water to splash out, potentially injuring operators and polluting the surrounding environment. Furthermore, it cannot guarantee the representativeness of the collected water samples, as the water quality may vary at different locations within the sewage pipes, making it difficult to accurately control the sampling location during manual collection. In addition, manual sampling is inefficient and cannot meet the needs of real-time monitoring.

[0004] Therefore, we provide a water sample collection structure for cooling tower drain pipes. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned technical problems by providing a water sample collection structure for cooling tower drainage pipes. By optimizing the shelf adjustment structure and control method, it solves the problem of inconvenience in retrieving items when multiple people are using the existing loading table at the same time, thereby improving kitchen work efficiency and operational safety.

[0006] In view of this, the present invention provides a water sample collection structure for a cooling tower drain pipe, including a drain pipe body, a sampling component and a control component;

[0007] The sewage pipe body is equipped with a sampling interface, which is connected to the interior of the sewage pipe body.

[0008] The sampling assembly includes a connecting tube and a sampling bottle. One end of the connecting tube is detachably connected to the sampling interface, and the other end is connected to the inside of the sampling bottle.

[0009] The control component includes a solenoid valve and a controller. The solenoid valve is mounted on a connecting pipe and is used to control the opening and closing of the connecting pipe. The controller is electrically connected to the solenoid valve and is used to control the opening and closing of the solenoid valve.

[0010] Preferably, the sampling interface is provided with an internal thread, and the end of the connecting pipe connected to the sampling interface is provided with an external thread that matches the internal thread.

[0011] Preferably, rubber rings are provided at the upper and lower ports of the connecting pipe.

[0012] Preferably, the control component further includes a wireless communication module, which is electrically connected to the controller. The wireless communication module is used to receive external control signals and transmit the signals to the controller.

[0013] Preferably, the sewage pipe body is also equipped with a pressure sensor, which is electrically connected to the controller. The pressure sensor is used to detect the water pressure inside the sewage pipe body and transmit the water pressure signal to the controller.

[0014] Preferably, the controller is equipped with a timing control module for controlling the opening and closing of the solenoid valve according to a preset time.

[0015] Preferably, an auxiliary structure is provided between the connecting tube and the sampling bottle. The auxiliary structure includes a rectangular holder with a through cavity. The connecting tube is screwed to the upper cavity of the rectangular holder, and the sampling bottle is screwed to the lower cavity of the rectangular holder via a threaded structure.

[0016] Preferably, one end of the rectangular card holder is provided with a side cavity, and a sealing partition is provided at the side cavity in a pull-out manner. The sealing partition can completely fill the rectangular card holder, and one end of the sealing partition is also provided with a protruding handle.

[0017] Compared with the prior art, this utility model provides a water sample collection structure for cooling tower sewage pipes, which has the following beneficial effects:

[0018] 1. This utility model, by installing a solenoid valve on the connecting pipe and cooperating with a controller for remote or automatic control, avoids direct contact between personnel and sewage with unstable water pressure in the sewage pipe. During the water sample collection process, there is no need for manual operation of valves that are prone to splashing water, thus eliminating the risk of water sample splashing causing injury to operators from the source, and at the same time preventing sewage from splashing out and polluting the environment.

[0019] 2. This utility model, by installing a pressure sensor on the sewage pipe body, monitors the water pressure inside the pipe in real time and transmits the signal to the controller. The controller accurately controls the opening time and on / off of the solenoid valve based on the water pressure data, ensuring that each water sample collected comes from a suitable location inside the sewage pipe and that the collection volume is stable. This effectively avoids the problem of water samples lacking representativeness due to inaccurate sampling location and large fluctuations in collection volume, and provides more reliable data support for water quality monitoring.

[0020] 3. This utility model, by setting up a wireless communication module and a timing control module in the control component, allows operators to remotely send control signals through external devices or preset the sampling time in advance. The controller automatically controls the solenoid valve to collect water samples, eliminating the need for frequent on-site operations. This enables real-time and timed collection of water samples from cooling tower sewage pipes, greatly improving sampling efficiency and meeting the timeliness requirements of water quality monitoring.

[0021] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Example 1: A water sample collection structure for a cooling tower drain pipe, such as... Figures 1-4 As shown, it includes a sewage pipe body 1, a sampling component 2, and a control component 3;

[0030] The sewage pipe body 1 is equipped with a sampling interface 11, which is connected to the interior of the sewage pipe body 1.

[0031] The sampling assembly 2 includes a connecting tube 21 and a sampling bottle 22. One end of the connecting tube 21 is detachably connected to the sampling interface 11, and the other end is connected to the inside of the sampling bottle 22.

[0032] The control component 3 includes a solenoid valve 31 and a controller 32. The solenoid valve 31 is mounted on the connecting pipe 21 and is used to control the opening and closing of the connecting pipe 21. The controller 32 is electrically connected to the solenoid valve 31 and is used to control the opening and closing of the solenoid valve 31.

[0033] In use, tighten the connection between the threaded end of the connecting pipe 21 (211) and the internally threaded sampling interface 11 on the sewage pipe body 1, ensuring a good seal between the rubber rings at the upper and lower ends of the connecting pipe 21 to prevent water sample leakage. Connect the sampling bottle 22 to the other end of the connecting pipe 21, and then establish a connection with the wireless communication module 33 via an external device. Set the sampling time of the timing control module in the controller 32, and set parameters such as the opening duration of the solenoid valve 31 corresponding to the data detected by the pressure sensor 12 according to actual needs. When the sampling time preset by the timing control module is reached, or when the operator sends a water sample collection command via an external device, the wireless communication module 33 transmits the command to the controller 32. The controller 32 receives the sampling trigger signal and, before preparing to open the solenoid valve 31 for water sample collection, the pressure sensor 12 detects the water pressure in the sewage pipe body 1 in real time and records the water pressure... The signal is transmitted to the controller 32, which analyzes and judges the water pressure signal to confirm whether the current water pressure is within a safe and suitable range for sampling. If the controller 32 judges that the water pressure is normal, it sends an opening command to the solenoid valve 31. The solenoid valve 31 opens, and the sewage in the sewage pipe body 1 enters the connecting pipe 21 through the sampling interface 11 under the action of water pressure, and then flows into the sampling bottle 22. During this process, the controller 32 accurately controls the opening duration of the solenoid valve 31 based on the real-time water pressure data fed back by the pressure sensor 12 and the preset sampling volume requirements. When the preset water sample collection volume or collection time is reached, the controller 32 sends a closing command to the solenoid valve 31, and the solenoid valve 31 closes, stopping the water sample collection. At this time, the operator can obtain the feedback information of the sampling completion through the wireless communication module 33, or go to the sampling point during subsequent inspections to remove the sampling bottle 22 for water sample testing and analysis.

[0034] like Figures 1-4As shown, rubber rings are provided at the upper and lower ports of the connecting pipe 21. The rubber rings ensure the sealing of the connection between the connecting pipe 21 and the sampling interface 11 of the sewage pipe body 1, preventing sewage from seeping out from the interface under pressure, thus avoiding environmental pollution and resource waste. The rubber ring at the lower port ensures the seal between the connecting pipe 21 and the sampling bottle 22, preventing water sample leakage or outside air from entering the sampling bottle 22 during the collection process, which would affect the authenticity of the water sample and the test results.

[0035] like Figures 1-4 As shown, the control component 3 also includes a wireless communication module 33, which is electrically connected to the controller 32. The wireless communication module 33 is used to receive external control signals and transmit the signals to the controller 32. The sewage pipe body 1 is also equipped with a pressure sensor 12, which is electrically connected to the controller 32. The pressure sensor 12 is used to detect the water pressure in the sewage pipe body 1 and transmit the water pressure signal to the controller 32. The controller 32 is equipped with a timing control module, which is used to control the opening and closing of the solenoid valve 31 according to a preset time. It should be noted that the circuit connection and working principle between the solenoid valve 31, the controller 32 and the wireless communication module 33 mentioned above are all existing technologies well known to those skilled in the art, and will not be described in detail here.

[0036] Example 2: A water sample collection structure for a cooling tower drain pipe, such as... Figures 1-4 As shown, an auxiliary structure is provided between the connecting tube 21 and the sampling bottle 22. The auxiliary structure includes a rectangular card holder 4 with a through cavity. The connecting tube 21 is screwed to the upper cavity 41 of the rectangular card holder 4, and the sampling bottle 22 is screwed to the lower cavity of the rectangular card holder 4 via a threaded structure 221.

[0037] The rectangular card holder 4 has a side cavity 42 at one end, and a sealing partition 43 is provided at the side cavity 42 in a pull-out manner. The sealing partition 43 can completely fill the rectangular card holder 4, and a protruding handle 431 is also provided at one end of the sealing partition 43.

[0038] During use, the removable sealing partition 43 at the side cavity opening 42 can block or open the inner cavity of the rectangular card holder 4 as needed. Before sampling, the sealing partition 43 is in the inserted state, which can effectively prevent sewage from the sewage pipe body 1 from accidentally flowing into the sampling bottle 22 through the connecting pipe 21. When sampling is required, the sealing partition 43 can be pulled out, and the sewage can smoothly enter the sampling bottle 22 through the rectangular card holder 4, realizing flexible control of the sampling process and avoiding water sample waste or unnecessary pollution. Furthermore, by completely filling the rectangular card holder 4 with the sealing partition 43, and with the protruding handle 431, the inner cavity of the rectangular card holder 4 can be kept sealed in the closed state, preventing sewage leakage and the entry of external impurities, further improving the sealing performance of the water sample collection device, ensuring the purity of the collected water sample and the accuracy of the test results. When the sampling bottle 22 is removed, the sealing partition 43 can be pushed into the rectangular card holder 4 in advance to prevent the sampling bottle 22 from contacting the outside air when it is removed, which could lead to inaccurate subsequent tests.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
