[0038] ​Specifically, the main frame 1 serves as a protective cover, covering the outside of the float ball liquid level controller 3, the top filter hole 13 and the bottom filter hole 14 of the main frame 1 and the side filter hole 21 on the isolation plate 2 can isolate the floating objects; when the device is placed or taken out, the arrangement of the top filter hole 13 and the bottom filter hole 14 is also beneficial to the flow of liquid; and the top filter hole 13 can also serve as an observation effect, so the size of the top filter hole 13 can be appropriately increased; the main frame 1 can adopt a stainless steel bar as a skeleton, for example, can be a cuboid; the number of the isolation plate 2 is four, which is distributed around the main frame 1, and the side filter hole 21 can be a circular grid hole; by uniformly drilling the circular grid hole on the isolation plate 2, the hexagonal of the main frame 1 can be watered, and the slightly larger suspended objects can be isolated, so that the slightly larger suspended objects cannot be attached to the float ball liquid level controller 3, the action accuracy of the float ball liquid level controller 3 is ensured, and the environmental accidents of burning the motor and causing sewage overflow due to the float ball liquid level controller 3 are avoided;

[0039] Further, the control cable 4 is a complete cable, and the connection between the connection section 41 and the transmission section 42 is in a connected state, and the connection between the connection section 41 and the transmission section 42 is fixed on the main frame 1, and when the float ball liquid level controller 3 is triggered, the connection section 41 is pulled tight; when the float ball liquid level control device is used, the device can be tied and fixed in the sewage pool and the water collecting well, and the device can be directly placed in the sewage when used; by adjusting the length of the connection end in the control cable 4, the water level control range can be changed, so that the float ball liquid level control device sends start and stop signals to the drainage equipment such as the water pump.

[0040] The float ball liquid level control device provided by the utility model can effectively avoid the burning of the motor and the sewage overflow caused by the too much suspended objects in the sewage, the attachment of the slightly larger suspended objects on the float ball, the action failure of the float ball liquid level controller 3 and the major environmental accidents caused thereby; the device reduces the equipment maintenance cost, improves the reliability of the electrical equipment and ensures the safety production; and the manufacturing cost is low. The float ball liquid level control device is suitable for popularization and use in the sewage system and can be used in various environments of the sewage treatment system.

[0041] In some embodiments, a cable limiting component 5 for limiting the position of the control cable 4 is further included, and the cable limiting component 5 is installed on the main frame 1; through the arrangement of the cable limiting component 5, the connection stability of the main frame 1 and the control cable 4 can be ensured.

[0042] In some embodiments, the cable limiting part 5 is in the shape of a ring, is fixed on the main body frame 1, and the control cable 4 is fixed on the cable limiting part 5 after penetrating through the cable limiting part 5. The ring-shaped cable limiting part 5 can facilitate the penetration of the control cable 4 and the adjustment of the length of the connecting section 41 of the control cable 4.

[0043] In some embodiments, the position of the cable limiting part 5 relative to the main body frame 1 is adjustable. For example, the cable limiting part 5 can be a buckle, and the cable limiting part 5 can be fixed on the main body frame 1 according to actual needs. When the detection needs change, the position of the control cable 4 connected to the main body frame 1 can be changed by adjusting the position of the cable limiting part 5. Specifically, the cable limiting part 5 can be arranged at the middle position of the main body frame 1. In this way, when the floating ball liquid level controller 3 rises to the first height or falls to the second height, the floating ball liquid level controller 3 can be triggered. That is, when the connecting section 41 of the control cable 4 is stretched, the floating ball liquid level controller 3 will send an on or off signal, and at this time, the drainage device can be turned on or off, completing the entire water pumping process.

[0044] In some embodiments, the isolation plate 2 is a phenolic cloth plate, and the thickness of the isolation plate 2 is 1-3 mm; and / or the side filter hole 21 is a circular hole, the diameter of the filter hole is 18-22 mm, and the spacing between adjacent side filter holes 21 is 8-12 mm. Specifically, the phenolic cloth plate is an insulating plate with good toughness and corrosion resistance. The thickness of the isolation plate 2 is selected to be 1-3 mm, preferably 2 mm, which is light in weight and low in cost. The diameter of the filter hole should be set according to the size of the suspended solids in the sewage, which can block slightly larger suspended solids. The spacing between adjacent side filter holes 21 should not be too large to allow water flow, nor too small to allow suspended solids to enter the inside of the main body frame 1. The vertical four sides of the device use a phenolic cloth plate with a relatively small thickness as the isolation plate 2, which not only ensures the strength of the main body frame 1, but also ensures corrosion resistance and reduces the weight of the floating ball liquid level control device, facilitating transportation and installation.

[0045] In some embodiments, the main body frame 1 is formed by welding a plurality of steel bars, which is high in strength and convenient to process.

[0046] In some embodiments, the top left and right sides and / or the front and back sides of the main body frame 1 are fixed with lifting rings 16, which facilitate the lifting of the main body frame 1.

Specifically, the top filtering component 12 can be welded by thin stainless steel wires, and the top filtering hole 13 is in a long strip structure. Of course, the bottom of the frame body 11 can also be welded by thin stainless steel wires first, and then fixed at the bottom of the frame body 11. The detachable connection between the top filtering component 12 and the frame body 11 is for the convenience of maintaining the floating ball liquid level controller 3.

[0048] In some embodiments, a binding component 6 is further included, and the top filtering component 12 is mounted on the frame body 11 through the binding component 6. Specifically, the top filtering component 12 and the frame body 11 are fixed by binding, which facilitates the replacement of the floating ball liquid level controller 3. The binding is used instead of the hinge to fix the top filtering component 12, which avoids the problem that the top filtering component 12 cannot be opened in time due to corrosion and impurities in sewage, and ensures the timeliness of replacing the floating ball liquid level controller 3.

[0049] In some embodiments, the top filtering hole 13 is in a rectangular shape, which facilitates the maintenance personnel to clearly observe the situation of the floating ball liquid level controller 3 in the sewage.

[0050] In some embodiments, the bottom filtering hole 14 is in a rectangular shape, which facilitates the flow of liquid and the putting or taking out of the device into or from the sewage system.

[0051] In some embodiments, the top of the main body frame 1 is provided with a long slot 15, the isolation plate 2 is detachably mounted in the long slot 15, and the bottom of the long slot 15 is provided with a supporting part 151 for supporting the isolation plate 2. Specifically, the long slot 15 is welded by steel bars on the upper end face of the main body frame 1 in the front, rear, left and right directions according to the thickness of the isolation plate 2. The maintenance personnel can frequently lift the floating ball liquid level control device and pull out the isolation plate 2, which facilitates the cleaning or replacement of the isolation plate 2. The isolation plate 2 can be freely inserted and pulled out from above the long slot 15. When the isolation plate 2 is placed in place, the bottom of the isolation plate 2 is just placed on the supporting part 151, which ensures the stability of the isolation plate 2. The supporting part 151 can also be welded by steel bars.

[0052] Further, the top of the long slot 15 is provided with a scraping strip 152, which is parallel to the surface of the isolation plate 2, so as to scrape off the attachments on the surface of the isolation plate 2 when the isolation plate 2 is taken out of the long slot 15. Specifically, through the provision of the scraping strip 152, the attachments on the isolation plate 2 can be scraped off by the scraping strip 152 when the isolation plate 2 is taken out, so as to ensure the sewage passing property, ensure the free floating of the float ball liquid level controller 3 in the sewage, ensure the accuracy of the liquid level detection signal, and realize the reliable action of the drainage equipment.

[0053] In some embodiments, the top of the isolation plate 2 is provided with a handle 22, and the height of the isolation plate 2 is greater than the height of the long slot 15. Specifically, after the isolation plate 2 is placed into the long slot 15, the handle 22 is located outside the long slot 15, so as to facilitate the disassembly and assembly of the isolation plate 2.
