Description

Technical Field

[0001] The utility model belongs to the technical field of water supply devices, and particularly relates to a bacteria detection sampling device for water supply devices. Background Art

[0002] Tap water refers to water that meets the relevant standards and is produced after being purified and disinfected by a water treatment plant for people's daily life and production. Domestic water is mainly drawn from rivers, lakes, groundwater, and surface water through the water plant's water intake pump station. The water plant is treated by sedimentation, disinfection, filtration and other process flows in accordance with the "National Sanitary Standards for Drinking Water". Finally, it is delivered to each user through a water distribution pump station. Before the tap water is delivered, the water quality in the water pipe needs to be tested for bacteria.

[0003] At present, a Chinese utility model with publication number: CN210711558U discloses a water supply device bacteria detection sampling device, which belongs to the field of bacteria detection technology, including: a tap water pipe, a protective cover and a detection instrument are installed above the tap water pipe, a detection area and a time control switch are arranged inside the protective cover, a detection probe and a heating rod are arranged inside the detection area, the detection area is connected with a water inlet pipe and an inner discharge pipe that pass through the tap water pipe and an outer discharge pipe that pass through the protective shell, the water inlet pipe is located in the tap water pipe. A water collecting cup is arranged at one end, and an electric water valve is arranged on the outer discharge pipe. The water supply device bacteria detection sampling device can detect the water quality in the tap water pipe at a fixed time and frequency, and discharge unqualified water samples after treatment. The structural design is reasonable and practical.

[0004] Although the above patent can detect the water quality in the tap water pipe at a fixed time and frequency, we believe that there is still a defect of mobility; the detection device is fixedly connected to the tap water pipe through the water inlet pipe and the inner discharge pipe, which also makes it impossible to separate the detection device and the tap water pipe, so it is not convenient to dismantle, repair and replace the detection device, and no matter which one is damaged first, they need to be discarded together, which is wasteful; at the same time, because the water inlet pipe can only receive part of the water source flowing through the tap water pipe, even if the water quality problem is detected, the tap water pipe cannot be blocked, which causes the water that has not entered from the water inlet pipe to be discharged through the tap water pipe, and the practicality is low. Utility Model Content

[0005] The utility model aims to provide a water supply device bacteria detection sampling device, which has the advantages that the detection device can be disassembled from the water pipe for maintenance and replacement and can timely block the water pipe when water quality problems are detected.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a bacteria detection sampling device for a water supply device, comprising a tap water pipe, a fixed sleeve fixedly connected to the surface of the tap water pipe, one side of the inner wall of the fixed sleeve is respectively fixedly connected with a water inlet pipe and an inner discharge pipe connected to the tap water pipe, the tops of the water inlet pipe and the inner discharge pipe are fixedly connected with an electronic three-way valve, a mounting shell is arranged on the top of the surface of the fixed sleeve, a connecting sleeve threadedly connected to one end of the electronic three-way valve away from the water inlet pipe and the inner discharge pipe is threadedly connected to one end of the electronic three-way valve, and magnet sheets magnetically connected to each other are installed between the mounting shell and the fixed sleeve, a detection inner cavity connected to the connecting sleeve is opened inside the mounting shell, a detection probe is installed on the top of the detection inner cavity, and a time-controlled switch used in conjunction with the detection probe is installed inside the mounting shell.

[0007] By adopting the above technical scheme, the installation shell is magnetically installed on the tap water pipe that needs to be tested by using a magnet sheet, and then the connecting sleeve is rotated to move forward so that the connecting sleeve threaded sleeve is connected to the end of the electronic three-way valve away from the water inlet pipe and the inner discharge pipe, thereby connecting the detection cavity with the electronic three-way valve for detection. The detection device can be removed from the tap water pipe for maintenance and replacement, so that the installation shell can be removed from the tap water pipe and stored after the detection is completed, waiting for the next use; when the detection instrument detects that there is a problem with the water quality, the time-controlled switch controls the motor to rotate in the opposite direction, so that the impact of the water flow inside the tap water pipe drives the sealing plate to rotate upward to close the sealing port to prevent water from flowing through. The function of timely blocking the tap water pipe when a problem with the water quality is detected is achieved, thereby preventing the problematic water source from continuing to flow and improving safety.

[0008] The utility model is further configured as follows: a sealing port is opened inside the tap water pipe, one side of the sealing port is rotatably connected to a sealing plate, the inside of the fixed sleeve is slidably connected to a pull wire fixedly connected to the sealing plate, one end of the fixed sleeve is rotatably connected to a winding wheel wound around the pull wire, and a motor fixedly connected to the winding wheel is installed on one side of the outside of the fixed sleeve.

[0009] By adopting the above technical solution, the water pipe can be blocked in time when water quality problems are detected, thereby preventing the problematic water source from continuing to flow and improving safety.

[0010] The utility model is further configured as follows: a detection instrument used in conjunction with the detection probe is installed on the top of the installation shell.

[0011] By adopting the above technical solution, the detection instrument is arranged outside, which can also facilitate personnel to observe the water quality data after inspection.

[0012] The utility model is further configured as follows: a heating rod is fixedly installed at the bottom of the detection inner cavity, and the electronic three-way valve, the detection probe, the heating rod and the time-controlled switch are all electrically connected to an external power supply through a wire.

[0013] By adopting the above technical solution, the heating rod is powered on and started by a time-controlled switch, so that the water sample in the detection cavity can be sterilized at high temperature before being discharged, thereby avoiding direct discharge of the water sample to pollute the external environment.

[0014] The utility model is further configured as follows: one end of the detection inner cavity away from the connecting sleeve is connected to an external discharge valve pipe fixedly connected to the mounting shell.

[0015] By adopting the above technical solution, the residual water source inside the detection cavity can be discharged cleanly by controlling the opening of the external discharge valve pipe through the time-controlled switch to prevent affecting the next detection.

[0016] The utility model is further configured as follows: a roller rotatably connected to the interior of the fixing sleeve is slidably connected to the pull wire.

[0017] By adopting the above technical solution, the friction force of the pull wire sliding inside the fixing sleeve is reduced.

[0018] The utility model is further configured as follows: a sealing ring is bonded to one side of the sealing opening close to the sealing plate.

[0019] The above technical solution is adopted to improve the sealing performance of the sealing plate in sealing the sealing opening.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. The installation shell is magnetically connected to the water pipe to be tested by using a magnet, and then the connecting sleeve is rotated to move forward so that the connecting sleeve is threadedly sleeved on the end of the electronic three-way valve away from the water inlet pipe and the inner discharge pipe, so that the detection inner cavity is connected with the electronic three-way valve for detection. The detection device can be removed from the water pipe for maintenance and replacement, so that after the detection is completed, the installation shell can be removed from the water pipe and stored, waiting for the next use;

[0022] 2. When the detection instrument detects that there is a problem with the water quality, the time switch controls the motor to rotate in the opposite direction, so that the impact of the water flow inside the water pipe drives the sealing plate to rotate upward to close the sealing port to prevent water from flowing through. This achieves the function of sealing the water pipe in time when a problem with the water quality is detected, thereby preventing the problematic water source from continuing to flow and improving safety.
