The floating ball is arranged on the guide pipe in a sliding mode, a cleaning ring is arranged above the floating ball, and the inner wall of the cleaning ring is in threaded connection with the peripheral wall of the guide pipe. When the liquid level rises, the floating ball rises along with the liquid level, the cleaning ring is arranged above the floating ball, when the floating ball rises, the cleaning ring is pushed to rise, and due to the fact that the cleaning ring is connected with the peripheral wall of the guide pipe in a threaded mode, the cleaning ring pushed by the floating ball rotates, and dirt and impurities on the guide pipe are cleaned. Therefore, the position of the floating ball sensed by the conduit is more accurate, and the measurement accuracy is further ensured.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of liquid level meter equipment, and particularly relates to a suspended mechanical liquid level sensor sensing assembly. BACKGROUND

[0002] The suspended mechanical liquid level sensor, also called a float ball type liquid level meter, is composed of a float ball and a rod, etc. The float ball is equivalent to a sensing assembly in the entire liquid level sensor. According to the principle of equal liquid displacement, the float ball floats on the liquid surface. When the liquid level in the container changes, the float ball also moves up and down. Due to the magnetic effect, the dry spring of the float ball liquid level meter is magnetically attracted to change the liquid level position into an electrical signal. The actual position of the liquid is displayed by a digital display instrument. The float ball liquid level meter thus achieves remote detection and control of the liquid surface.

[0003] When applied in the field of dirty media and sewage treatment, impurities in the liquid easily adhere to the rod above the liquid surface. The impurities below the liquid surface are in a suspended state and do not affect the movement of the magnetic float ball. When liquid is added to the container, the impurities easily prevent the float ball from moving, thereby affecting the movement of the float ball and causing great inconvenience to the use of the float ball type liquid level meter. CONTENT OF THE UTILITY MODEL

[0019] The present application will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams that only schematically illustrate the basic structure of the present application, and thus only show the components relevant to the present application.

[0020] As Figures 1-4 shown, a floating mechanical liquid level sensor sensing assembly includes a float ball 1 and a conduit 2; the float ball 1 is slidingly arranged on the conduit 2, and a cleaning ring 3 is arranged above the float ball 1, and the inner wall of the cleaning ring 3 is screwed with the outer peripheral wall of the conduit 2.

[0021] When the liquid level rises, the float ball 1 rises with the liquid surface, the cleaning ring 3 is arranged above the float ball 1, when the float ball 1 rises, the cleaning ring 3 is pushed to rise, since the cleaning ring 3 is screwed with the outer peripheral wall of the conduit 2, the cleaning ring 3 pushed by the float ball 1 will rotate, thereby cleaning the dirt and impurities on the conduit 2 to ensure that the position of the conduit 2 sensing float ball 1 is more accurate, further ensuring the accuracy of measurement.

[0022] In some further embodiments, the cleaning ring 3 is provided with an annular weight-reducing groove 30, and the opening of the annular weight-reducing groove 30 is located on the outer peripheral wall of the cleaning ring 3.

[0023] In order to avoid the cleaning ring 3 being too heavy to affect the natural floating of the floating ball 1, the annular weight-reducing groove 30 is particularly provided on the cleaning ring 3, and the annular weight-reducing groove 30 is opened on the outer peripheral wall of the cleaning ring 3. The advantage of this arrangement is that the complete top wall and bottom wall of the cleaning ring 3 can still be retained, thereby satisfying the abutment of the floating ball 1.

[0024] In some further embodiments, the cleaning ring 3 is provided with a hinged column 4, the hinged column 4 is hingedly provided with a scraper 5, and the hinged column 4 is sleeved with a torsion spring 6, one end of the torsion spring 6 abuts against the scraper 5, and the other end of the torsion spring 6 abuts against the hinged column 4, so that the side wall of the scraper 5 is always attached to the outer peripheral wall of the conduit 2.

[0025] The scraper 5 can rotate relative to the hinged column 4, and the hinged column 4 is provided with the torsion spring 6. Under the action of the torsion spring 6, the scraper 5 is always attached to the outer peripheral wall of the conduit 2. Therefore, when the cleaning ring 3 rises under the action of the floating ball 1, the cleaning ring 3 rotates under the action of the screw connection, and then the scraper 5 moves circumferentially to scrape off the impurities attached to the conduit 2.

[0026] In some further embodiments, the scraper 5 is provided with a scraping hole 60, and a pair of opposite edges of the scraping hole 60 located in the horizontal plane are provided with scraping edges 61.

[0027] In order to improve the ability of the scraper 5 to clean impurities, the scraper 5 is provided with a scraping hole 60 penetrating the thickness direction of the scraper 5. In this embodiment, the scraper 5 is vertically arranged, and a pair of opposite edges of the scraping hole 60 located in the horizontal plane are provided with scraping edges 61. In this embodiment, the scraping edges 61 are integrally arranged with the edges of the scraping hole 60, that is, the edges of the scraping hole 60 are the scraping edges 61.

[0028] When the scraper 5 rotates relative to the conduit 2, the scraping edges 61 can scrape the outer peripheral wall of the conduit 2. Compared with the scraping of the outer wall of the conduit 2 by the side wall of the scraper 5, the scraping edges 61 can better clean the impurities attached to the conduit 2.

[0029] It should be noted that the cleaning ring 3 has a certain weight, and the cooperation between the internal thread arranged on the inner wall of the cleaning ring 3 and the external thread arranged on the outer peripheral wall of the conduit 2 is different from the cooperation of the traditional bolt and nut. The thread pitch between the cleaning ring 3 and the conduit 2 is large, and the thread inclination degree is large, that is, it is more inclined to be vertically arranged, so as to ensure that the self-weight of the cleaning ring 3 can drive the entire cleaning ring 3 to slowly rotate downward step by step.

[0030] In addition, the elasticity of the torsion spring 6 is relatively small, so as not to affect the self-sliding of the cleaning ring 3.

[0031] When the cleaning ring 3 slides down under the action of gravity, one side of the scraping hole 60 on the scraper 5 can still clean the outer circumferential wall of the pipe 2, further ensuring the cleaning effect.

[0032] In some further embodiments, the cleaning ring 3 is provided with a cleaning brush 8, and the bristle end of the cleaning brush 8 abuts the outer circumferential wall of the pipe 2.

[0033] The cleaning brush 8 is used to assist in cleaning the outer circumferential wall of the pipe 2, and the bristle end of the cleaning brush 8 slightly abuts the outer circumferential wall of the pipe 2, which ensures contact and avoids excessive interference with the rotation of the cleaning ring 3 relative to the pipe 2.

[0034] In some further embodiments, the hinge column 4 and the cleaning brush 8 are each provided with three groups in a circumferential direction.

[0035] The hinge column 4 and the cleaning brush 8 are each provided with three groups in a circumferential direction, so as to ensure the cleaning effect on the outer circumferential wall of the pipe 2.

[0036] In some other embodiments, the hinge column 4 is provided with a blocking ring 7 to avoid slipping between the scraper 5 and the hinge column 4.

[0037] Obviously, the above embodiments are only examples for the sake of clarity, and are not a limitation on the embodiments. Based on the above description, those skilled in the art can make other different forms of changes or modifications. Here, it is not necessary and impossible to exhaust all the embodiments. The obvious changes or modifications derived therefrom are still within the protection scope of the present application.
