Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to an intelligent anti-drowning and biofilm-attached safety rope device for biological pools in wastewater treatment plants. Background Technology

[0002] The biological treatment tank in a wastewater treatment plant is the core purification unit of the entire wastewater treatment system. It artificially creates a suitable environment to cultivate and utilize aerobic, anaerobic, and facultative microorganisms from a large amount of activated sludge to biodegrade and transform harmful substances in the wastewater, such as organic pollutants, ammonia nitrogen, and total phosphorus. The wastewater is thoroughly mixed and in contact with the microorganisms within the tank. The microorganisms use the pollutants as nutrients for metabolism, decomposing organic matter into carbon dioxide and water. Simultaneously, nitrogen and phosphorus pollution are removed through nitrification, denitrification, and biological phosphorus removal. Ultimately, the turbid, highly polluted wastewater is transformed into purified water that meets discharge or reuse standards. It is a key structure for achieving the harmless and resource-based treatment of wastewater.

[0003] The existing intelligent anti-drowning and biofilm safety rope devices for biological tanks in wastewater treatment plants have the following shortcomings: Currently, the biological tanks in wastewater treatment plants are all open areas. Although there are guardrails around the tanks, workers and visitors are prone to accidental falls into the water due to operational errors or loosening of the guardrails during inspections, maintenance, and visits. Traditional safety measures such as ordinary guardrails and lifebuoys have problems with delayed response and untimely rescue. However, building too many protective structures can affect the oxygenation effect, lighting, and water flow in the tank, reduce wastewater treatment efficiency, and easily cause odor accumulation, increase safety hazards, and hinder operation and maintenance. At the same time, traditional biofilm installation methods mostly use fixed support membrane carriers, which have poor installation flexibility, are prone to displacement of the membrane carriers due to water flow impact, and have insufficient biofilm uniformity, affecting biofilm stability and biofilm formation efficiency. In practical solutions to the above problems, the two solutions have problems with poor compatibility and low space and structural utilization. They also cannot simultaneously achieve a reliable protective structure and flexibility while minimizing the impact on lighting and ventilation.

[0004] Therefore, we proposed an intelligent anti-drowning and biofilm-attached safety rope device for biological ponds in wastewater treatment plants to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent anti-drowning and biofilm attachment safety rope device for biological tanks in wastewater treatment plants. This device is installed around the top of the wastewater tank, using railings for daily protection. In the event of a fall, a protective net composed of Z-shaped steel wire ropes provides support. A tension sensor detects the force and automatically alarms, driving a motor to wind up the steel wire ropes to tighten them. Simultaneously, a lifting mechanism raises the steel wire ropes for rescue. After completion, the device automatically resets. The device uses a float and automatic reel structure to prevent the rescue process from interfering with the normal operation of the biofilm attachment rope. Sliding rollers, elastic telescopic rods, and adjusting ropes guide, position, and adjust the steel wire ropes. The guide rollers reduce wear, and the device can be quickly disassembled and maintained using a support plate and quick-release structure. The overall structure is simple, does not affect the tank's lighting and ventilation, and balances protective reliability, emergency flexibility, and facility compatibility.

[0020] Example 1, according to Figure 1 - Figure 3As shown, to achieve the above objectives, the present invention provides the following technical solution: an intelligent anti-drowning and biofilm-attached safety rope device for a biological pool in a sewage treatment plant, comprising a biological pool body 1 and a protective net and biofilm-attached integrated mechanism 2. The protective net and biofilm-attached integrated mechanism 2 is located on the top of the biological pool body 1. The protective net and biofilm-attached integrated mechanism 2 includes a main frame 201. A protective rope opening 202 is provided on the outer side of the main frame 201. A first rope-pulling drive motor 204 is installed on the outer side of the main frame 201. A rope-retracting shaft 205 is installed at the output end of the first rope-pulling drive motor 204. The rope-retracting shaft 205 is located outside the protective rope opening 202. A steel wire rope 206 is sleeved on the outer side of the rope-retracting shaft 205. At the other end of the wire rope 206, a digital display tension alarm controller 214 is installed. Multiple rotating wheels 213 are fitted inside the wire rope 206.

Multiple fixing plate mounting slots 203 are opened around the top of the main frame 201. Motor fixing plates 209 are installed inside the mounting slots 203. A lifting drive motor 208 is installed inside the motor fixing plate 209. The other end of the lifting drive motor 208 is installed on the outside of the main frame 201. A height adjustment screw 210 is installed at the output end of the lifting drive motor 208. A central structural cavity 207 is opened inside the main frame 201. Located inside the central structural cavity 207, the bottom of the height adjusting screw 210 rotates to the top of the biological tank body 1. A central device frame 211 is installed inside the central structural cavity 207, and the central device frame 211 is threadedly connected to multiple height adjusting screws 210. Multiple rotating chambers 212 are opened inside the central device frame 211, and multiple rotating wheels 213 rotate inside the multiple rotating chambers 212 respectively. Multiple installation structural strips 221 are installed on the outer side of the wire rope 206. Three adjacent installation structural strips 221 are combined into a group. Two sliding rollers 222 are rotatably connected to the inner side of each installation structural strip 221. Multiple sliding rollers 222 are located on the outer side of the wire rope 206. A set of installation structural strips 221 is fitted with... Two quick-release connecting sleeves 223 are provided, and two elastic telescopic rods 224 are fitted inside the two quick-release connecting sleeves 223. The other ends of the two elastic telescopic rods 224 are rotatably connected to the two adjacent quick-release connecting sleeves 223. A connecting ring 225 is installed on the outer side of a set of mounting structure strips 221. A connecting frame 226 is installed on the outer side of the two adjacent elastic telescopic rods 224. An adjusting ring 227 is rotatably connected to the top inner side of the connecting frame 226. An adjusting rope 228 is provided on the inner side of multiple adjusting rings 227. A second pull rope drive motor 229 is installed on the top of the mounting structure strips 221. One end of the adjusting rope 228 is installed on the top of the central device frame 211, and the other end of the adjusting rope 228 is fitted on the output end of the second pull rope drive motor 229.

[0021] The overall effect of Embodiment 1 is as follows: This device is installed around the top of a traditional sewage tank. The guardrail 234 on top of the main frame 201 provides conventional protection. When a person falls into the tank, the continuous Z-shaped steel wire ropes 206 form a protective net to support them. To prevent the steel wire ropes 206 from deforming due to the weight of the person, the tension sensor built into the digital tension alarm controller 214 issues an alarm upon sensing tension. Simultaneously, the internal signal transceiver outputs a signal to activate the first rope-pulling drive motor 204. The first rope-pulling drive motor 204 drives the rope-retracting shaft 205 to rotate, thus retracting the rope... The shaft 205 continuously winds the wire rope 206, shortening the effective length of the wire rope 206 in the pool. The rotating wheel 213, sleeved on the inner side of the wire rope 206, provides limiting support for the wire rope 206 and rotates within the rotating wheel chamber 212, achieving synchronous winding of each section of the wire rope 206. This ensures uniform tension and prevents the wire rope 206 from becoming loose, shifting, or experiencing uneven stress during winding. To enable proactive emergency rescue of fallen personnel, the lifting drive motors 208 around the main frame 201 of the mechanism are simultaneously activated. Through the threaded engagement between the height adjustment screw 210 and the central device frame 211, the central device frame 211 is driven... 11. Move upwards within the main frame 201 of the mechanism to lift the personnel on the wire rope 206 to the top of the main frame 201. When the central device frame 211 rises to its limit position, the personnel can grab the guardrail 234 or wait for external rescue. After the trapped personnel leave the inside of the main frame 201, the digital display tension alarm controller 214 detects that the force on the wire rope 206 has returned to stability and restarts the height adjustment screw 210 to lower the central device frame 211 back to the bottom working position. During this process, to avoid affecting the normal operation of the biofilm hanging rope 233, the biofilm hanging rope 233 is supported by a float set at the top. The float 232 maintains its position. An automatic reel-in shaft 231 is located inside the float 232. The other end of the connecting rope 230 on the outside of the automatic reel-in shaft 231 is connected to the steel wire rope 206. Under normal working conditions, the biofilm hanging rope 233 passively releases the line by pulling the automatic reel-in shaft 231 under its own weight, causing the hanging rope to hang naturally. The float 232 keeps the biofilm hanging rope 233 at the standard water level through buoyancy. When the steel wire rope 206 rises to rescue personnel, the weight of the biofilm hanging rope 233 overcomes the reel-in elasticity of the automatic reel-in shaft 231, causing the automatic reel-in shaft 231 to automatically rotate and release the line, keeping the position of the biofilm hanging rope 233 basically unchanged.

[0022] Example 2, according to Figure 2 - Figure 11As shown, a limiting frame 215 is installed on the inner side of the central device frame 211, and a limiting groove 216 is opened on the outer side of the limiting frame 215. A first guide limiting frame 217 is installed on the inner side of the main frame 201 of the mechanism. Two first guide rollers 218 are rotatably connected to the inner side of the first guide limiting frame 217. The two first guide rollers 218 are located on the upper and lower sides of the protective rope opening 202, respectively. The first guide limiting frame 217 is located inside the limiting groove 216. A second guide limiting frame 219 is installed on the outer side of the central device frame 211. Two second guide rollers 220 are rotatably connected to the inner side of the second guide limiting frame 219. A connecting rope 230 is installed on the outer side of the connecting ring 225. An automatic take-up shaft 231 is sleeved on the inner side of the other end of the connecting rope 230. A float 232 is rotatably connected to the outer side of the automatic take-up shaft 231. A biofilm hanging rope 233 is installed at the bottom of the float 232.

[0023] The overall effect of Embodiment 2 is as follows: To further ensure that the biofilm hanging rope 233 is in the standard position, multiple installation structure strips 221 are set on the outside of the wire rope 206. Two sliding rollers 222 are rotatably set on the inner side of each installation structure strip 221. When the three installation structure strips 221 are combined to form a complete sleeve, the multiple sliding rollers 222 on the inner side surround the outside of the wire rope 206 and are fixed by quick-release connecting sleeves 223. The quick-release connecting sleeves 223 are rotatably connected to the elastic telescopic rod 224. The elastic telescopic rod 224 always pushes the quick-release connecting sleeves 223 on both sides to move outward. Since the wire rope 206 is arranged in a Z-shape, a V-shaped structure is formed between the multiple sets of sliding rollers 222 on it, and the elastic telescopic rod 224 always pushes the quick-release connecting sleeves 223 on both sides to move outward. Since the wire rope 206 is arranged in a Z-shape, a V-shaped structure is formed between the multiple sets of sliding rollers 222 on it, and the elastic telescopic rod 224 can move outward. The telescopic rod 224, through its own elasticity, pushes the sliding rollers 222 on both sides outward, thereby causing the two sets of sliding rollers 222 and the mounting structure strips 221 to retract inward. To control the position of the mounting structure strips 221, a connecting frame 226 is set on the outside of the elastic telescopic rod 224. An adjusting ring 227 is rotatably set on the top of the connecting frame 226. Adjusting ropes 228 are threaded through the inner side of multiple adjusting rings 227. One end of the adjusting rope 228 is fixed to the top of the central device frame 211, and the other end is wrapped around the output end of the second pull rope drive motor 229. When the second pull rope drive motor 229 is started and the adjusting rope 228 is wound, the shortened adjusting rope 228 pulls each set of mounting structure strips 221 through the adjusting rings 227, thereby driving the mounting structure strips 221 to retract inward. The structural bar 221 and the bottom quick-release connecting sleeve 223 move to adjust the position of the quick-release connecting sleeve 223, ensuring it remains in a suitable working position. The structural bar 221 is equipped with a limit frame 215, which accommodates changes in the connection between the wire rope 206 and the take-up / release rope shaft 205 during the ascent and descent of the central device frame 211. The protective rope opening 202 penetrates the inner wall of the main frame 201. A first guide limit frame 217 is installed at the other end of the protective rope opening 202, on the inner wall of the main frame 201. A first guide roller 218 rotates inside the first guide limit frame 217. The two first guide rollers 218 are located on the wire rope 206... The top and bottom of 06 prevent the wire rope 206 from contacting the main frame 201 of the mechanism and being damaged when the central device frame 211 moves the wire rope 206. The anti-limiting frame 215 has an anti-limiting groove 216 on its inner side to accommodate the first guide limit frame 217 to avoid limitation. The second guide limit frame 219 and the second guide roller 220 synchronously prevent the wire rope 206 from contacting the main frame 201 of the mechanism when moving. When it is necessary to disassemble and replace part of the connecting rope 230, a support plate is laid on the wire rope 206, and the personnel are on top of the support plate. The quick-release connecting sleeve 223 and the sliding roller 222 can be quickly disassembled by the quick-release connecting sleeve 223 itself for quick replacement.

[0024] The working principle of the entire device is as follows: This device is installed around the top of a traditional sewage tank. The guardrail 234 on the top of the main frame 201 functions as a traditional guardrail. In the event of a person falling into the tank, multiple continuous Z-shaped steel wire ropes 206 form a protective net to support the falling person. To prevent the steel wire ropes 206 from deforming due to the weight of the person, the built-in tension sensor in the digital tension alarm controller 214 senses the corresponding tension and activates the alarm. Simultaneously, the internal signal transceiver transmits a signal to activate the first rope drive motor 204. The first rope drive motor 204 drives the rope winding shaft 205 to rotate, causing the rope winding shaft 205 to continuously wind the steel wire ropes 206 around itself, thus ensuring the steel wire ropes 206 within the tank area are protected. The length is shortened, and the rotating wheel 213 sleeved inside the wire rope 206 provides limiting support for the wire rope 206. It rotates inside the rotating wheel chamber 212 to achieve synchronous winding of the wire rope 206 in all parts, ensuring uniform tension and preventing loosening, deviation, or uneven stress during winding. To facilitate emergency rescue of fallen personnel, the lifting drive motors 208 located around the main frame 201 are simultaneously activated. Through the threaded connection between the height adjusting screw 210 and the central device frame 211, the central device frame 211 is displaced and raised within the main frame 201, thereby lifting the personnel at the top of the wire rope 206 to the top of the main frame 201. The personnel are then lifted to the top of the central device frame 211. At the extreme height, the falling person can choose to pull on the guardrail 234 or wait for rescue. When the trapped person leaves the inner side of the main frame 201, the digital display tension alarm controller 214 detects the stable weight information of the wire rope 206. At this time, the height adjustment screw 210 is opened again to lower the central device frame 211 back to the bottom working position. During this period, in order to prevent the biofilm hanging rope 233 from being affected, a float 232 is installed on its top. The inner side of the float 232 rotates the automatic take-up shaft 231. The other end of the connecting rope 230 sleeved on the outer side of the automatic take-up shaft 231 is set on the outer side of the wire rope 206. During normal operation, the biofilm hanging rope 233 passively releases the line by pulling the automatic take-up shaft 231 with its own weight, so that the automatic take-up shaft 231 is passively released. The body hangs naturally, while the float 232, through its own buoyancy, keeps the biofilm suspending rope 233 at the standard water level. At this point, the descent ends. As the steel wire rope 206 is pulled upward to rescue personnel, the biofilm suspending rope 233, through its own weight, overcomes the elastic force of the automatic reel-in shaft 231. The automatic reel-in shaft 231 automatically rotates to release the line, keeping the biofilm suspending rope 233 stationary. To further ensure the biofilm suspending rope 233 is in the standard position, multiple installation structural strips 221 are installed on the outside of the steel wire rope 206. Each installation structural strip 221 has two sliding rollers 222 rotating on its inner side. When the three installation structural strips 221 form a complete sleeve, the multiple sliding rollers 222 inside will naturally surround the outside of the steel wire rope 206.Furthermore, this structure is fixed by quick-release connecting sleeves 223, and the rotational connection between quick-release connecting sleeves 223 and elastic telescopic rods 224 allows the elastic telescopic rods 224 to constantly push the quick-release connecting sleeves 223 on both sides outward. Because the wire rope 206 is Z-shaped, the multiple sets of sliding rollers 222 fitted on it are V-shaped. Thus, the elastic telescopic rods 224 use their own elasticity to spread the sliding rollers 222 on both sides to the sides, and further causes the two sets of sliding rollers 222 to drive the mounting structure strip 221 inward. In order to control the position of the mounting structure strip 221, a connecting rod is installed on the outside of the elastic telescopic rods 224. The connecting frame 226 has an adjusting ring 227 rotating on its top. Multiple adjusting rings 227 have adjusting ropes 228 inside. One end of each adjusting rope 228 is fixed to the top of the central device frame 211, and the other end is fitted onto the output end of the second rope-pulling drive motor 229. When the second rope-pulling drive motor 229 is activated, continuously winding the adjusting rope 228 around itself, the continuously shortening adjusting rope 228 pulls each set of mounting structure strips 221 through the adjusting rings 227. This causes the mounting structure strips 221 and their bottom-connected quick-release sleeves 223 to move, thereby adjusting the position of the quick-release sleeves 223 to ensure they are always in the appropriate position.
