Description

Technical Field

[0001] The invention belongs to the technical field of liquid level control devices, and in particular relates to a liquid level controller mounting bracket and a liquid level controller assembly. Background Art

[0002] The liquid level controller is used to control the liquid level in the container. When the liquid level reaches the upper or lower switching value, the controller contacts send out an on-off switch signal to control the actions of the solenoid valve, water pump, etc., thereby achieving semi-automation or full automation.

[0003] Conventional liquid level control and measurement devices include a float and a measuring tube. The measuring tube houses a measuring element that converts liquid level position signals into electrical signals. This signal is then digitally displayed on a display instrument, thereby enabling remote monitoring and control of the liquid level. Conventional liquid level control and measurement devices are secured to the controlled container via a flange.

[0034] The following is combined with Figure 1-7 The liquid level controller mounting bracket and the liquid level controller assembly of the present invention are further described.

[0035] Example 1

[0036] This embodiment discloses a liquid level controller mounting bracket.

[0037] Please refer to the attached Figure 1 、 Figure 4 and Figure 5 A liquid level controller mounting bracket is used to mount a liquid level control measuring device 3. The liquid level control measuring device 3 includes a measuring conduit 24. A float 26 is slidably connected to the outer side of the measuring conduit 24. The liquid level controller mounting bracket includes: a maintenance cleaning component 4, a position adjustment component connected to the liquid level control measuring device 3 and used to adjust the position of the liquid level control measuring device 3; the maintenance cleaning component 4 includes a clamping cleaning scraping module 29, a lifting scraping module and a distance adjustment module; the clamping cleaning scraping module 29 includes: a scraper 51, a matching arm 50 and an opening and closing drive unit, and the scraper There are two plates 51 and the two scrapers 51 are arranged opposite to each other. There are two matching arms 50, and the two matching arms 50 are fixed on the two scrapers 51 one by one. The opening and closing drive part is arranged between the two matching arms 50 and is used to drive the two scrapers 51 to open or close; the lifting and scraping module is connected to the opening and closing drive part, and is used to drive the scraper 51 to move back and forth along the length direction of the measuring tube 24; the distance adjustment module is connected to the liquid level control measuring device 3 and the lifting and scraping module, and is used to drive the lifting and scraping module carrying the clamping cleaning scraping module 29 to approach or move away from the measuring tube 24.

[0038] In this embodiment, the present invention utilizes a maintenance cleaning assembly 4 to scrape and clean dirt from the surface of the measuring conduit 24, ensuring that the surface of the measuring conduit 24 of the liquid level control measuring device 3 is not covered by underwater impurities, thereby ensuring measurement accuracy. Specifically, during normal use of the liquid level control measuring device 3, the two scrapers 51 are in an open position and away from the measuring conduit 24. When the measuring conduit 24 needs to be cleaned, the distance adjustment module drives the lifting and scraping module, carrying the clamping and cleaning scraping module 29, toward the measuring conduit 24. When the two scrapers 51 are facing the measuring conduit 24, they stop. The opening and closing drive unit then activates, causing the two scrapers 51 to embrace the outer wall of the measuring conduit 24. The lifting and scraping module then activates, driving the scrapers 51 to reciprocate along the length of the measuring conduit 24. This removes dirt adhering to the outer wall of the measuring conduit 24 and cleans the outer wall of the measuring conduit 24. After the cleaning is completed, the scraper 51 is opened again, and the distance adjustment module is used to drive the lifting scraper module to carry the clamping cleaning scraper module 29 away from the measuring conduit 24, so that the liquid level control measuring device 3 can continue to work normally.

For example, the opening and closing drive unit is a spiral transmission structure driven by a motor, which is an opening and closing structure similar to a wrench, or a structure that directly opens and closes using an oil cylinder or an air cylinder. Of course, it can also be Figure 7 The structure shown in (see detailed description below).
