Technical Field
[0001] This utility model relates to the technical field of drug leakage alarm equipment, and in particular to a drug leakage alarm device for a drug delivery port. Background Technology
[0002] During the daily operation of the water plant, it is necessary to regularly transport various solid / liquid agents such as PAC, lime, and sodium hypochlorite to the water plant via large specialized vehicles.
[0003] With some water plants now undergoing intelligent and modern upgrades, achieving minimal or no staffing, chemical dosing has become a critical operation. Traditional chemical dosing devices are relatively simple in structure, typically consisting of an inlet pipe, a delivery pipe, and a union. There have been incidents in the industry where, during dosing, large amounts of chemicals leaked due to pipe detachment, causing environmental pollution and a series of consequences.
[0004] In this context, optimizing the traditional pipe structure and setting up a leakage alarm system becomes particularly necessary.
[0005] Therefore, those skilled in the art have provided a drug delivery port leakage alarm device to solve the problems mentioned in the background art. Utility Model Content
[0006] This utility model provides a drug delivery port leakage alarm device that triggers an electrical signal at the pipe port when drug leakage occurs, simultaneously disconnecting the power supply to the drug delivery pump. This signal is sent to the water plant's central control system and activates a level one alarm, reminding on-duty personnel to handle the situation as soon as possible.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] This utility model provides a drug delivery port leakage alarm device, comprising:
[0009] A local power supply box, on which a buzzer is installed;
[0010] A dosing pump is connected to a local power supply box via a power line. The outlet end of the dosing pump is connected to the inlet end of the inlet pipe, and the outlet end of the inlet pipe is connected to the inlet end of the delivery pipe via a union connector.
[0011] The first leakage collection basin is located below the union joint. The leakage outlet at the bottom of the first leakage collection basin is connected to a leakage pipe, and a leakage sensor is installed on the leakage pipe.
[0012] Furthermore, the leakage sensor is connected to the local power supply box via a first signal line.
[0013] Furthermore, the bottom end of the leakage tube extends into the second leakage collection basin, and a solenoid valve is installed on the leakage tube near the second leakage collection basin. The solenoid valve is located below the leakage sensor.
[0014] Furthermore, the solenoid valve is connected to the local power supply box via a second signal line.
[0015] Furthermore, the live joint, the first leakage collection basin, the leakage pipe, the leakage sensor, the solenoid valve, and the second leakage collection basin are all housed inside the box, and the top of the box is provided with a cover that is hinged to it.
[0016] Furthermore, the local power supply box is connected to the PLC substation via a third signal line.
[0017] In the above technical solution, the drug delivery port leakage alarm device provided by this utility model has the following beneficial effects: when drug leakage occurs, the leakage sensor detects the drug information in the leakage tube, converts the information into an electrical signal and transmits it to the local power supply box, the local power supply box stops supplying power to the dosing pump and activates the buzzer alarm to remind the on-duty personnel to deal with it as soon as possible, so as to avoid losses caused by a large amount of drug leakage.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0027] See Figure 1 As shown;
[0028] The drug delivery port leakage alarm device described in this embodiment of the utility model includes:
[0029] Local power supply box 10, on which a buzzer 11 is installed;
[0030] The dosing pump 20 is connected to the local power supply box 10 via a power line 21. The outlet end of the dosing pump 20 is connected to the inlet end of the inlet pipe 22. The outlet end of the inlet pipe 22 is connected to the inlet end of the delivery pipe 24 via a union connector 23. The dosing pump 20 can deliver the medicine on the transport vehicle into the inlet pipe 22. The delivery pipe 24 is connected to the medicine storage tank and other medicine storage facilities.
[0031] The first leakage collection basin 30 is located below the union joint 23. The leakage outlet 31 at the bottom of the first leakage collection basin 30 is connected to the leakage pipe 32, and the leakage sensor 33 is installed on the leakage pipe 32.
[0032] The leakage sensor 33 is connected to the local power supply box 10 via the first signal line 34.
[0033] When a drug leak occurs during drug delivery, the leakage sensor 33 detects the drug information in the leakage tube 32, converts the information into an electrical signal and transmits it to the local power supply box 10. The local power supply box 10 stops supplying power to the drug dosing pump 20 and activates the buzzer 11 to alarm, reminding the on-duty personnel to handle the situation as soon as possible.
[0034] The first leakage collection basin 30 is used for the initial collection and subsequent leakage of the leaked medicine.
[0035] The leakage sensor used is the DJK-A6 sensor manufactured by Shenzhen Haomingxin Technology Co., Ltd.
[0036] The bottom end of the leakage tube 32 extends into the second leakage collection basin 35. A solenoid valve 36 is provided on the leakage tube 32 near the second leakage collection basin 35. The solenoid valve 36 is located below the leakage sensor 33. The solenoid valve 36 is connected to the local power supply box 10 through the second signal line 37.
[0037] When the solenoid valve 36 receives a remote command transmitted from the local power supply box 10, it locks the leaking tube to prevent the leaked medicine from spreading.
[0038] The local power supply box 10 is responsible for supplying power to the leakage sensor 33 and solenoid valve 36 of this device, as well as the dosing pump 20 on the transport vehicle, and maintaining the signal connection.
[0039] The live joint 23, the first leakage collection basin 30, the leakage pipe 32, the leakage sensor 33, the solenoid valve 36, and the second leakage collection basin 35 are all located inside the box 40, and the top of the box 40 is provided with a top cover 41 that is hinged to it.
[0040] The housing 40 is made of stainless steel, and the top cover 41 can be opened by pressing to access the internal components.
[0041] The local power supply box 10 is connected to the PLC substation 50 via the third signal line 12. The PLC substation 50 is connected to the local power supply box 10 and the upper-level plant control system, and is responsible for receiving and transmitting control commands.
[0042] In practical use, when the agent leaks from the union 23, it will first be initially collected by the first leakage collection 30 and flow down through the leak 31, triggering the leakage sensor 33. The trigger signal is transmitted to the local power supply box 10 and the PLC substation 50, and the preset program is activated. The PLC substation 50 issues a control command to the local power supply box 10 to shut off the power to the dosing pump 20 loaded on the transport vehicle and stop the agent application.
[0043] After installation at the work site, this application can provide early warning of leakage during the filling process of various liquid / solid agents, preventing losses caused by large-scale leakage. At the same time, a camera can be installed, which will record the filling process and transmit the data to the upper-level plant control system.
[0044] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
