Description

Technical Field

[0001] This utility model relates to the technical field of sewage treatment systems, and more specifically, to a float switch mounting bracket for sewage tanks and a sewage treatment system. Background Technology

[0002] In wastewater treatment systems, liquid level monitoring is a crucial aspect of ensuring stable system operation. Float switches are typically used to monitor the wastewater tank level in real time, and the level signals are used to control related equipment, ensuring the orderly progress of wastewater treatment processes. Among these, the installation status of the float switch directly affects the accuracy and reliability of the liquid level detection.

[0003] Currently, commonly used float switches in wastewater treatment systems, such as cable-binding type and weighted float switches, have significant drawbacks in practical applications. Specifically, the wastewater tanks in wastewater treatment systems are mostly enclosed enclosures with only one inlet. This inlet often needs to accommodate multiple booster pumps, pump set fixing chains, pump set cables, pumping pipelines, and other equipment and components. However, since float switches are currently used directly from the wastewater tank opening, due to the lack of a specific installation and fixing structure, during long-term operation, the float switches are easily obstructed or entangled by the booster pumps, pump set fixing chains, pump set cables, pumping pipelines, and other equipment and components. This can prevent the signal nodes from functioning properly or resetting, leading to abnormal operation of the wastewater treatment system.

[0004] Therefore, there is an urgent need for a mounting bracket that can stably fix the float switch and prevent it from interfering with other equipment, so as to improve the reliability of liquid level monitoring in sewage treatment systems. Utility Model Content

The horizontal frame is connected between the lower end of the first vertical frame and the upper end of the second vertical frame. The second vertical frame is equipped with a connector for connecting a float switch.

[0007] According to a preferred embodiment, the mounting bracket is suitable for a weighted float switch, which includes a weight, a float, and a connecting cable.

[0012] According to a preferred embodiment, a connecting nut is provided at the lower middle part of the X-shaped bracket, and a threaded section is provided at the upper end of the first vertical frame, the threaded section being threadedly engaged with the connecting nut.

[0013] According to a preferred embodiment, the bending bracket further includes a diagonal brace, the first end of which is connected to a first vertical frame, and the second end of which is connected to a second vertical frame.

[0014] According to a preferred embodiment, the bending bracket and / or diagonal brace are formed by welding corrosion-resistant steel.

[0015] This utility model also provides a sewage treatment system, including the float switch mounting bracket for sewage tanks as described above.

[0016] The technical solution of the float switch mounting bracket and sewage treatment system for sewage tank provided by this utility model has at least the following advantages and beneficial effects: (1) Through the tenon and mortise structure set on the outside of the fixing part, on the one hand, it can form a stable connection with the pool opening, avoiding the displacement of the bracket as a whole at the sewage tank inlet. On the other hand, no welding is required during installation, thereby avoiding the interaction with the flammable gas generated by the sewage tank during welding, reducing safety risks; (2) Through the rotational cooperation between the first vertical frame and the lower end face of the fixing part, the orientation of the bending bracket can be flexibly adjusted, further avoiding other equipment at the inlet, preventing the float switch from being blocked or entangled, and ensuring the normal operation and reset of the signal node; (3) Through the adaptive fit between the connecting ring and the counterweight, the counterweight can be... The combination of the limiting function and the fixing effect of the bracket makes the balance limiting of the float by the weight more stable and reduces the shaking of the float caused by external force; in addition, the sliding characteristics of the connecting ring can be adjusted with the weight of the weight to adjust the overall installation height of the float switch, which can not only meet the needs of different liquid level detection ranges, but also further limit the vertical displacement of the float switch through the synergistic effect of the weight and the connecting ring, and prevent it from moving close to other equipment due to positional movement, thereby enhancing the anti-interference effect and the accuracy of liquid level detection; (4) The limiting block can directly limit the maximum sliding position of the connecting ring, prevent it from falling off the second vertical frame, and ensure that the weight and the float are always stably connected to the second vertical frame through the connecting ring, ensuring that the balance limiting function of the weight on the float is continuously effective and preventing The failure of the float switch due to the detachment of the connecting ring further improves the reliability and safety of the float switch fixed by the mounting bracket; (5) The connecting cable can be fixed in an orderly manner on the bending bracket by the cable management clip, avoiding the cable from swinging or drooping at will, eliminating the risk of the cable getting tangled with other equipment from the structure, and reducing the interference of the cable on the float's movement with the liquid level change, ensuring the sensitivity of the float switch signal node; (6) The cross structure of the X-type bracket can maximize the reduction of the space occupied by the sewage tank inlet while ensuring a stable connection with the pool opening by cooperating with the outer tenon structure. The hollow design of the X-type bracket can avoid spatial conflict with other equipment and reduce the installation interference problem caused by the large volume of the fixing part; at the same time, the X-type structure through The intersection forms a concentrated stress area, which can achieve stable support for the lower bending bracket and float switch with a lighter overall weight, enhance the structural stability and load-bearing capacity of the fixed part, and ensure that it is not easily deformed by external force or vibration during long-term use, providing a reliable foundation support for the stable installation and anti-interference effect of the float switch; (7) The diagonal brace, together with the first vertical frame, the horizontal frame and the second vertical frame, form a triangular stable structure. The geometric stability of the triangle significantly enhances the overall structural strength and anti-deformation ability of the Z-type bending bracket; and in the complex environment of the sewage tank, even if subjected to the force of the float switch itself, slight water flow disturbance or external vibration, the bending bracket is not easy to bend or shake, ensuring the stability of the installation position of the float switch.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] Example 1 This embodiment provides a mounting bracket for a float switch used in a sewage treatment plant. Figure 1 See the structural diagram of the support bracket for the float switch in this sewage tank. Figure 1 As shown, the floating switch mounting bracket for the sewage tank includes a fixing part 100 adapted to the opening of the sewage tank, and the outer side of the fixing part 100 is provided with a tenon and mortise structure.

[0020] In this embodiment, the tenon and mortise structure provided on the outside of the fixing part 100 can form a stable connection with the pool opening, preventing the entire support from shifting at the sewage pool inlet. On the other hand, no welding is required during installation, thereby avoiding the interaction with flammable gases generated in the sewage pool during welding and reducing safety risks.

[0021] The lower end of the fixing part 100 is provided with a bending bracket 200; in a preferred embodiment, the bending bracket 200 is Z-shaped and is composed of a first vertical frame 210, a horizontal frame 220 and a second vertical frame 230. The upper end of the first vertical frame 210 is vertically installed on the lower end face of the fixing part 100 and rotates with the lower end face of the fixing part 100. The horizontal frame 220 is connected between the lower end of the first vertical frame 210 and the upper end of the second vertical frame 230. The second vertical frame 230 is provided with a connector for connecting the float switch 300.

[0022] Specifically, in this embodiment, the first vertical frame 210 and the lower end face of the fixed part 100 are rotated together, which can flexibly adjust the orientation of the bending bracket 200, further avoid other equipment at the entrance, prevent the float ball 320 switch 300 from being blocked or tangled, and ensure the normal operation and reset of the signal node.

[0023] Example 2 This embodiment further explains the structure of the mounting bracket based on the technical solution provided in Embodiment 1: In this embodiment, see Figure 2 As shown, the mounting bracket is suitable for the 310-type float 320 switch 300. The 310-type float 320 switch 300 includes a 310-type weight, a 320-type float, and a connecting cable 330. The first end of the connecting cable 330 is connected to the 320-type float, and the second end of the connecting cable 330 passes through the 310-type weight. The connector is a connecting ring 231 that is adapted to the shape of the 310-type weight. The connecting ring 231 is slidably mounted on the second vertical bracket 230.

[0024] In this embodiment, the fitting between the connecting ring 231 and the counterweight 310 combines the limiting function of the counterweight 310 with the fixing function of the bracket, making the balance limiting of the float 320 by the counterweight 310 more stable and reducing the shaking of the float 320 caused by external forces. In addition, the sliding characteristics of the connecting ring 231 can be used to adjust the overall installation height of the float 320 switch 300 in conjunction with the weight of the counterweight 310. This can not only meet the needs of different liquid level detection ranges, but also further limit the vertical displacement of the float 320 switch 300 through the synergistic effect of the counterweight 310 and the connecting ring 231, preventing it from moving closer to other equipment due to positional shifts, thereby enhancing the anti-interference effect and the accuracy of liquid level detection.

[0025] The end of the second vertical frame 230 is provided with a limiting block; the limiting block provided in this embodiment can directly limit the maximum sliding position of the connecting ring 231, prevent it from falling off the second vertical frame 230, ensure that the counterweight 310 and the float 320 are always stably connected to the second vertical frame 230 through the connecting ring 231, ensure that the balance limiting function of the counterweight 310 on the float 320 is continuously effective, avoid the failure of the float 320 switch 300 due to the falling off of the connecting ring 231, and further improve the reliability and safety of the mounting bracket fixing the float 320 switch 300.

[0026] The bending bracket 200 is provided with several cable management clips at intervals; in this embodiment, the connecting cable 330 can be fixed in an orderly manner on the bending bracket 200 by the cable management clips, so as to avoid the cable swinging or drooping at will, thereby eliminating the risk of the cable getting tangled with other equipment from the structure, and reducing the interference of the cable on the float 320 as the liquid level changes, thus ensuring the sensitivity of the signal node of the float 320 switch 300.

[0027] The bending bracket 200 also includes a diagonal brace 240. The first end of the diagonal brace 240 is connected to the first vertical frame 210, and the second end of the diagonal brace 240 is connected to the second vertical frame 230. In this embodiment, the diagonal brace 240, together with the first vertical frame 210, the horizontal frame 220, and the second vertical frame 230, form a triangular stable structure. The geometric stability of the triangle significantly enhances the overall structural strength and deformation resistance of the Z-shaped bending bracket 200. Therefore, even in the complex environment of the sewage tank, the bending bracket 200 is not prone to bending or shaking even when subjected to the weight of the float switch 300 itself, slight disturbance of water flow, or external vibration, ensuring the stability of the installation position of the float switch 300.

[0028] The bending bracket 200 and / or the diagonal brace 240 are welded from corrosion-resistant steel, which can effectively resist the erosion of sewage, moisture and various corrosive impurities in the sewage tank environment. This avoids problems such as rust and reduced structural strength of the bending bracket 200 and / or diagonal brace 240 due to long-term contact with corrosive media, significantly extending the service life of the bracket and reducing the frequency of maintenance and replacement due to material corrosion.

[0029] Example 3 Based on the technical solution provided in Embodiment 2, this embodiment further explains the structure of the fixing part 100: In this embodiment, the fixing part 100 is an X-shaped bracket. The cross structure of the X-shaped bracket can ensure a stable connection with the pool opening while minimizing the space occupied by the sewage pool inlet. The hollow design of the X-shaped bracket can avoid spatial conflicts with other equipment and reduce installation interference problems caused by the excessive size of the fixing part 100. At the same time, the X-shaped structure forms a concentrated force area through the intersection point, which can achieve stable support for the lower bending bracket 200 and the float switch 300 with a lighter overall weight, enhance the structural stability and load-bearing capacity of the fixing part 100, and ensure that it is not easily deformed by external forces or vibrations during long-term use, providing a reliable foundation support for the stable installation and anti-interference effect of the float switch 300.

[0030] In some specific embodiments, the X-shaped bracket is formed by welding angle steel 110. It should be noted that the angle steel 110 itself has high structural strength and rigidity. The X-shaped bracket formed by welding can provide a stable support foundation for the entire installation bracket, ensuring that the fixing part 100 is not easily deformed by bending the bracket 200 and the weight of the float ball 320 switch 300 or external vibration after being connected to the sewage tank opening, thus improving the overall structural stability of the bracket.

[0031] The lower middle part of the X-shaped bracket is provided with a connecting nut 120, and the upper end of the first vertical bracket 210 is provided with a threaded section, which is threadedly engaged with the connecting nut 120. On the one hand, the threaded connection allows for flexible adjustment of the orientation of the bent bracket 200, further avoiding other equipment at the entrance and preventing the float switch 300 from being blocked or entangled, ensuring the normal operation and reset of the signal node. On the other hand, the threaded connection enables the first vertical bracket 210 to be detachably connected to the fixing part 100, facilitating the disassembly and transportation of the bracket, on-site assembly, and subsequent maintenance and replacement, thus improving the ease of bracket installation. In addition, by rotating the first vertical bracket 210, the extension length of the first vertical bracket 210 can be precisely adjusted by utilizing the relative movement of the threaded section and the connecting nut 120, thereby adjusting the overall installation depth of the bent bracket 200 and the float switch 300.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
