Description

Technical Field

[0001] This utility model relates to the field of biological pond technology, specifically to an extended transmission mechanism for an electric actuator used in a biological pond water control valve. Background Technology

[0002] In the operation system of a wastewater treatment plant, the water control valves in the biological treatment tank are key equipment for regulating the water volume within the tank and ensuring the stable progress of the wastewater treatment process. Biological treatment tanks typically have multiple valves of this type, all centrally installed in valve wells approximately 3 meters deep. The opening and closing of these valves directly affects the continuity of the wastewater treatment process; their operational reliability and safety are crucial for the efficient operation and maintenance of the wastewater treatment plant.

[0003] However, existing valve installations have the following problems: First, high operational safety risks. Since the valves are all located underground, maintenance personnel must descend into the well to operate them each time. The 3-meter-deep valve well environment is narrow and prone to water accumulation, posing safety hazards such as slipping and oxygen deficiency during the process, threatening the personal safety of maintenance personnel. Second, insufficient reliability of the drainage pump control. To prevent water accumulation in the well from damaging the valve's electric actuator, each valve well is equipped with a drainage pump, relying on a float switch for automatic water control. When the rainwater in the well reaches the warning level, the float switch triggers the drainage pump to start lowering the water level. However, in actual application, the float switch has a high failure rate, often experiencing trigger failure or delay, resulting in rainwater not being discharged in time. Third, the electric actuator is easily damaged and has high maintenance costs. Due to insufficient waterproofing of the electric actuator itself, when the float switch fails and rainwater overflows the actuator, it is very easy to cause short circuits, corrosion, and other damage to the actuator. This not only affects the normal opening and closing of the valve but also requires frequent repairs or replacements of the actuator, significantly increasing equipment maintenance costs and interfering with the continuity of the wastewater treatment process.

[0036] Combination Figure 1 - As shown in Figure 7, the extended transmission mechanism of the electric actuator for the biological tank water control valve provided by this utility model includes:

[0037] The electric actuator 1 has an output square shaft 13 at its output end; the transmission tube 2 has an upper flange 21 at its top end, which is assembled and connected to the first mating flange 11 of the electric actuator 1; the transmission tube 2 has an upper bearing 24 at its top inside and a lower bearing 25 at its bottom inside; the side wall of the transmission tube 2 has a clamp 3 for fixing the cable 12, which is connected to the electric actuator 1; the inner transmission rod 23 is installed inside the upper bearing 24 and the lower bearing 25, and the inner transmission rod 23 is coaxially positioned... Inside the transmission tube 2, the top end of the inner transmission rod 23 is fitted with an output square shaft 13; a liquid valve 7, the second mating flange 71 at the top of the liquid valve 7 is connected to the lower flange 22 at the bottom end of the transmission tube 2, and the top control end of the liquid valve 7 is connected to the bottom end of the inner transmission rod 23; both ends of the liquid valve 7 are flanged and connected to the liquid guide pipe 8; a support assembly 4 is located at the top of the biological tank 6; a clamping assembly 5 is located at the top of the support assembly 4, and the transmission tube 2 passes through the clamping assembly 5 and the support assembly 4. The clamping assembly 5 is used to clamp and position the transmission tube 2.

[0038] In the above scheme: 1. The transmission tube 2 enables the extended connection between the electric actuator 1 and the liquid valve 7. The inner transmission rod 23 is positioned by the upper bearing 24 and the lower bearing 25, ensuring no offset or shaking during transmission, precise torque transmission, and efficient long-distance opening and closing control of the liquid valve 7. 2. The transmission tube 2 encloses the inner transmission rod 23 to prevent corrosion and wear of the transmission components, extending its service life; the cable clamp 3 fixes the cable 12 to prevent friction damage between the cable 12 and the transmission tube 2 or the biological tank 6 structure, ensuring circuit safety. 3. The support component 4 provides bottom support for the transmission tube 2, and the clamping component 5 clamps and positions it from the top. With the flange connection at both ends, a multi-fixed structure of "fixed at both ends + clamped in the middle" is formed, which has strong overall rigidity and resists the vibration of the surrounding environment of the biological tank 6. 4. The modular design of each component allows for quick assembly and disassembly of the electric actuator 1, transmission tube 2, and liquid valve 7 via flanges; no major modifications to the biological tank 6 or liquid valve 7 are required, adapting to the existing liquid valve extension and upgrade needs, reducing modification and maintenance costs.

[0039] In this embodiment, the output end of the electric actuator 1 is provided with a first docking flange 11, the top end of the transmission tube 2 is provided with an upper flange 21, and the upper flange 21 is assembled and connected with the first docking flange 11; the bottom end of the transmission tube 2 is provided with a lower flange 22, the top outer ring of the hydraulic valve 7 is provided with a second docking flange 71, and the lower flange 22 is assembled and connected with the second docking flange 71.

[0040] In the above scheme, the corresponding assembly of the first mating flange 11 with the upper flange 21 and the lower flange 22 with the second mating flange 71 provides a precise positioning reference for the transmission tube 2, the electric actuator 1, and the hydraulic valve 7, ensuring that the inner transmission rod 23 is coaxially connected with the output square shaft 13 and the control end of the hydraulic valve 7, avoiding transmission jamming or torque transmission loss. The flanges are assembled with bolts, resulting in high connection strength.

[0041] In this embodiment, the top end of the inner transmission rod 23 is provided with a slot 231, the output end of the electric actuator 1 is provided with an output square shaft 13, and the output square shaft 13 is inserted into the slot 231; the bottom end of the inner transmission rod 23 is provided with a transmission square shaft 232, the control end of the hydraulic valve 7 is provided with a socket 72, and the transmission square shaft 232 is inserted into the socket 72.

[0042] In the above scheme, the square mating structure of the output square shaft 13 and slot 231, and the transmission square shaft 232 and socket 72 ensures that there is no relative slippage when transmitting torque, thus ensuring that the power of the electric actuator 1 is accurately transmitted to the hydraulic valve 7, and realizing precise control of the opening and closing angle of the hydraulic valve 7.

[0043] In this embodiment, the support component 4 includes a first crossbeam 41 and a second crossbeam 42, which are arranged in a mirror-symmetrical manner, and a gap is left between the first crossbeam 41 and the second crossbeam 42 for the transmission tube 2 to pass through; the surfaces of the first crossbeam 41 and the second crossbeam 42 are both provided with adjustment grooves 43.

[0044] In the above scheme: the first crossbeam 41 and the second crossbeam 42 are arranged in a mirror-symmetrical manner to form a stable support base, providing central support for the transmission protective pipe 2, avoiding sagging or vibration during transmission due to excessive length, and enhancing the overall structural stability. The adjustment groove 43 on the surface of the crossbeam can adjust the support position to adapt to different installation layouts on the top of the biological tank 6 and the installation requirements of the transmission protective pipe 2, eliminating the need for customized special support components and improving the versatility of the equipment.

[0045] In this embodiment, the clamping assembly 5 includes a first side clamping plate 51 and a second side clamping plate 52. The first side clamping plate 51 and the second side clamping plate 52 are arranged in a mirror symmetrical manner. The bottom of the first side clamping plate 51 and the second side clamping plate 52 are provided with positioning holes 54. The positioning holes 54 are located at the top of the adjusting groove 43. A locking stud 55 passes through the inside of the positioning holes 54. The bottom of the locking stud 55 is externally threaded with a locking nut 56. The inner walls of the first side clamping plate 51 and the second side clamping plate 52 are both provided with arc-shaped mating grooves 53.

[0046] In the above scheme: the arc-shaped mating grooves 53 of the first side clamping plate 51 and the second side clamping plate 52 fit against the outer wall of the transmission tube 2, forming symmetrical clamping forces from both sides, fixing it firmly, effectively limiting the radial sway of the transmission tube 2, and ensuring transmission accuracy. The locking stud 55 passes through the positioning hole 54 and the adjustment groove 43 of the support component 4, which can not only fix the side clamping plates, but also finely adjust the position of the clamping component 5 through the adjustment groove 43, thereby calibrating the installation posture of the transmission tube 2 and ensuring precise docking with the electric actuator 1 and the hydraulic valve 7. The arc-shaped mating groove 53 fits tightly against the outer wall of the transmission tube 2, avoiding excessive local force during clamping and damage to the tube wall; the clamping distance can be adjusted by the cooperation of the locking stud 55 and the locking nut 56, adapting to transmission tubes 2 of different diameters, with strong versatility; at the same time, the clamping structure further enhances the middle fixing effect of the transmission tube 2 and improves the overall rigidity.

[0047] The working principle and usage process of this utility model are as follows: When extending and improving the operating end of the liquid valve 7, the original electric actuator 1 is removed, and the lower flange 22 at the bottom of the transmission tube 2 is connected to the second docking flange 71 of the liquid valve 7, so that the transmission square shaft 232 is inserted into the socket 72; then, the first crossbeam 41 and the second crossbeam 42 of the support assembly 4 are welded to the top of the biological tank 6 at the corresponding installation positions of the transmission tube 2, and the transmission tube 2 is placed between the first crossbeam 41 and the second crossbeam 42. Then, the first side clamping plate 51 and the second side clamping plate 52 of the clamping assembly 5 are alternately placed above the first crossbeam 41 and the second crossbeam 42, and the first side clamping plate 51 and the second side clamping plate 52 are attached to both sides of the transmission tube 2. The positioning hole 54 is connected to the adjusting groove 43. The locking stud 55 is passed through the positioning hole 54 and the adjusting groove 43, and then the locking stud 55 is... Tighten the locking nut 56 to the protruding end of 5 to position the first side clamp 51 and the second side clamp 52. The first side clamp 51 and the second side clamp 52 clamp the positioning transmission tube 2 from the top. Connect the first docking flange 11 of the electric actuator 1 to the upper flange 21 with bolts. Insert the output square shaft 13 into the slot 231. Pass the cable 12 through the wire hole 61 of the biological tank 6 and fix it to the side wall of the transmission tube 2 with the wire clamp 3. Finally, the cable 12 is connected to the electric actuator 1 located at the top of the transmission tube 2. When the improved valve is controlled: the electric actuator 1 drives the output square shaft 13 to rotate, and then drives the inner transmission rod 23 to rotate through the slot 231. The upper bearing 24 and the lower bearing 25 constrain the rotation of the inner transmission rod 23. The bottom end of the inner transmission rod 23 drives the liquid valve 7 to open and close through the transmission square shaft 232 and the socket 72.
