Description

Technical Field

[0001] This application relates to the field of municipal pipeline water quality testing technology, and in particular to a water quality sensor mounting fixture. Background Technology

[0002] With the acceleration of urbanization, the scale of municipal drainage pipe networks is constantly expanding, and the network structure is becoming increasingly complex. Real-time water quality monitoring has become a core requirement for environmental governance, pollution source tracing, and the operation and maintenance of municipal facilities. In related technologies, installers need to carry sensors and sensor mounting brackets into the rainwater or sewage wells of municipal pipelines. First, the mounting bracket is installed at the bottom of the rainwater or sewage well, and then the sensor is installed on the corresponding mounting bracket, so that the sensor's detection end can extend into the water. Regarding the above-mentioned technologies, the inventors believe that it is inconvenient for installers to enter the well to install the mounting brackets and sensors. Utility Model Content

[0003] To facilitate the installation of sensors within the well, this application provides a water quality sensor mounting fixture.

[0004] This application provides a water quality sensor mounting fixture, which adopts the following technical solution:

The outer side wall of the fixture base has a clamping groove for arranging the sensor and is also provided with a metal clamping piece for pressing the sensor into the clamping groove. Both ends of the metal clamping piece are provided with mounting screws that cooperate with the fixture base. The extension bracket includes a fixing plate mounted on the top surface of the fixture base and an extension rod connected to the fixing plate.

[0006] By adopting the above technical solution, when clamping the water quality sensor, the installer can place the sensor in the clamping groove of the clamp base, press the sensor into the clamping groove on the side wall of the clamp base by the metal clamping piece, and lock it with the mounting screw, so that the sensor is clamped by the metal clamping piece. Then the installer places the extension bracket on the side wall of the well. Compared with the installation method of the installer carrying the sensor and sensor mounting bracket into the rainwater well or sewage well of the municipal pipeline, the above installation method allows the installer to install the extension bracket and sensor without entering the well.

[0007] Optionally, the outer wall of the clamp base is provided with four clamping slots.

[0008] By adopting the above technical solution, four clamping slots are set on a fixture base, which enables four sensors to be clamped on the fixture base, thereby facilitating the installation of multiple sensors.

[0013] Optionally, the top of the first connecting rod is provided with a first retaining ring, and the bottom of the second connecting rod is provided with a second retaining ring; the detachable connector has a retaining ring groove for the first retaining ring and the second retaining ring to abut against each other; the detachable connector includes a first retaining piece and a second retaining piece, one end of the first retaining piece and one end of the second retaining piece are hinged together, and the other end of the first retaining piece and the other end of the second retaining piece are engaged by a screw and threaded sleeve structure.

[0014] By adopting the above technical solution, the specific structure of the above detachable connector is disclosed. When the above detachable connector is used to fix the extension rod, the first connecting rod and the second connecting rod are quickly fixed by hinged one end of the first snap-fit ​​piece and the second snap-fit ​​piece and the other end is engaged by the screw and threaded sleeve structure.

[0015] Optionally, an mounting plate is installed on the outer wall of the first snap-fit ​​piece, and the mounting plate has a mounting through hole.

[0016] By adopting the above technical solution, it is convenient for installers to fix the mounting piece to the side wall of the first snap-fit ​​piece through the mounting through hole.

[0017] Optionally, it also includes a mounting base for mounting on the sidewall of the well body, the mounting base having a snap-fit ​​groove for snap-fitting the mounting piece, and the mounting base also having an arrangement through groove for arranging the detachable connector.

[0018] By adopting the above technical solution, the specific structure of the mounting base is disclosed, which facilitates the installer to snap the mounting piece into the snap-fit ​​groove on the mounting base and fix the mounting base to the side wall of the well body.

[0019] Optionally, a cleaning assembly is also included, which is mounted on the fixture base. The cleaning assembly includes a drive motor that runs through the upper and lower surfaces of the fixture base and a brush head structure mounted on the output shaft of the drive motor for cleaning the sensor detection end. The output shaft of the drive motor is located on the lower side of the fixture base.

[0020] By adopting the above technical solution, the specific structure of the cleaning component described above is disclosed. Using the above cleaning component facilitates the cleaning of dirt on the surface of the sensor detection end.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] A water quality sensor mounting fixture includes a fixture base and an extension bracket connected to the fixture base. By locking the sensor to the fixture base and fixing the fixture base to the extension bracket by a fixing plate, it is convenient for installers to arrange the sensor and the extension bracket in the well body.

[0023] By setting a detachable connector to detachably connect the first link and the second link, it is easy for installers to install and remove the first link and the second link, and further facilitates the storage and transportation of the extension bracket.

[0024] The mounting base set on the side wall of the well body makes it easy for installers to snap the mounting plate into the slot and fix the mounting base to the side wall of the well body. Attached Figure Description
