Description

Technical Field

[0001] This utility model relates to the field of water tank chlorination and disinfection technology, and in particular to a secondary water supply water tank chlorination and disinfection system based on incremental PID control. Background Technology

[0002] With the acceleration of urbanization, secondary water supply facilities have played an important role in solving the water supply problem of high-rise buildings. However, secondary water supply facilities are prone to secondary pollution, which poses a potential threat to the drinking water safety of users. In order to deal with this problem, chlorination disinfection technology has been widely used.

[0003] In existing secondary water supply chlorination and disinfection systems, the conventional technical solutions mainly rely on sensors to monitor the residual chlorine content in the water in real time. Based on the monitoring data, the control system will adjust the operation of the chlorination equipment to ensure that the water quality meets the standards.

[0004] In existing technologies, when using chlorination disinfection equipment for secondary water supply tanks, chlorine is discharged through a chlorination pump, and disinfection is carried out through automated chlorine discharge. However, during long-term use, if the system malfunctions or there is a power outage, the chlorine discharge cannot be carried out, requiring a long time for repairs. This also affects the normal water use of residents and fails to meet the needs of users. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a secondary water supply tank chlorination and disinfection system based on incremental PID control, which aims to improve the problem in the prior art that the system cannot perform chlorine discharge when problems occur or power outages occur during long-term use.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a secondary water supply tank chlorination disinfection system based on incremental PID control, comprising a water supply tank and a connecting belt. An external frame is fixedly connected to the front side of the water supply tank. A drive motor is fixedly connected to the top right side of the external frame. A fixing block is fixedly connected to the output end of the drive motor. A driving pulley is installed on the rear side of the fixing block. A driven pulley is rotatably connected to the top left side of the external frame. The driven pulley is connected to the driving pulley via the connecting belt. A driving bevel gear is fixedly connected to the rear side of the driven pulley. A vertical rod is rotatably connected to the left and right sides of the inside of the water supply tank. A driven bevel gear is fixedly connected to the middle of the outer wall of the vertical rod, and the driven bevel gear is drivingly connected to the driving bevel gear. A baffle is fixedly connected to the top of the vertical rod. Storage tanks are installed on the left and right sides of the top of the water supply tank. A fixed plate is fixedly connected to the inner bottom wall of the storage tank. A stirring blade is fixedly connected to the end of the vertical rod. A warning mechanism is installed on the outside of the water supply tank to indicate the residual chlorine content in the storage tank to the staff.

[0007] Through the above technical solution: the drive motor is started to make the fixed block one rotate; the fixed block one cooperates with the slot; the cooperation between the fixed block one and the slot, and the synchronous rotation of the drive pulley, drive the driven pulley to rotate accordingly through the connecting belt, thereby driving the driven bevel gear, baffle and stirring blade to rotate synchronously; the rotation of the stirring blade ensures that water and chlorine are fully mixed, thereby improving water purification efficiency.

[0008] As a further description of the above technical solution:

[0009] The prompting mechanism includes a float plate, which is disposed inside the liquid storage tank. A rubber band is fixedly connected to the outer side of the float plate, and a ball is installed at the end of the rubber band. Slanted drawers are fixedly connected to the left and right sides of the outer wall of the water supply tank. Hollow columns are fixedly connected to the left and right sides of the water supply tank. Copper drums are installed on the left and right sides of the bottom of the water supply tank.

[0010] The above technical solution works as follows: the drop in water level will cause the floating plate to drop synchronously, which will stretch the rubber belt and break it due to the force, resulting in a sphere that will eventually fall freely onto the bronze drum; the bronze drum will make a loud sound after being hit, thus alerting the staff to the chlorine content.

[0011] As a further description of the above technical solution:

[0012] A knob is provided on the top left side of the external frame, and a fixing block two is fixedly connected to the top of the knob.

[0013] The above technical solution involves engaging the second fixing block with the slot, and then rotating the knob to drive the transmission of other structures.

[0014] As a further description of the above technical solution:

[0015] The front side of the drive pulley is provided with a slot, and both the first fixing block and the second fixing block are engaged with the slot.

[0016] Through the above technical solution, the cooperation between the fixed block and the slot drives the synchronous rotation of the drive pulley.

[0017] As a further description of the above technical solution:

[0018] The bottom wall of the water supply tank is connected by multiple arc-shaped pipes at equal intervals, and valves are installed on the outside of the arc-shaped pipes.

[0019] The above technical solution involves using an arc-shaped pipe to discharge purified water, and a valve to control the opening and closing of the arc-shaped pipe.

[0020] As a further description of the above technical solution:

[0021] A chlorination pump is installed on the top rear side of the water supply tank. The input end of the chlorination pump is connected to a water inlet pipe, and a sealing ring is installed on the outside of the rubber belt.

[0022] The above technical solution involves starting the chlorination pump to drive the inlet pipe and introduce chlorine into the system, while ensuring the sealing rings at the openings are airtight.

[0023] As a further description of the above technical solution:

[0024] The output end of the chlorination pump is connected to a drain pipe, and the end of the drain pipe is connected to the top of the storage tank.

[0025] The above technical solution involves transporting chlorine to a storage tank via a drain pipe.

[0026] As a further description of the above technical solution:

[0027] An observation window is installed on the front side of the water supply tank, and the observation window is threadedly connected to the water supply tank by bolts.

[0028] The above technical solution allows the observation window to be opened and closed using bolts, through which the water level can be observed.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, the drive motor drives the fixed block to rotate. The engagement of the fixed block with the slot causes the drive pulley to rotate synchronously, thereby driving the driven bevel gear, the baffle and the stirring blade to rotate synchronously. The rotation of the stirring blade fully mixes the water and chlorine, accelerating the water purification efficiency. In case of system failure or power outage, rotating the knob can drive the transmission of other structures, thus avoiding the impact on residents' normal water use.

[0031] 2. In this utility model, the rubber belt is pulled to extend it. When the rubber belt breaks under force, the ball falls freely onto the bronze drum. The bronze drum makes a loud sound when it is subjected to force, thereby indicating to the staff the residual chlorine level inside the bronze drum, which brings convenience to the user.

Detailed Implementation

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Reference Figure 1 , Figure 2 and Figure 5This utility model provides an embodiment of a secondary water supply tank chlorination and disinfection system based on incremental PID control, comprising a water supply tank 1 and a connecting belt 14. An external frame 3 is fixedly connected to the front side of the water supply tank 1. A drive motor 19 is fixedly connected to the top right side of the external frame 3. A fixing block 20 is fixedly connected to the output end of the drive motor 19. A drive pulley 21 is installed on the rear side of the fixing block 20. A driven pulley 18 is rotatably connected to the top left side of the external frame 3. The driven pulley 18 is connected to the drive pulley 21 via the connecting belt 14. Both the drive pulley 21 and the driven pulley 18 are fixedly connected to the rear side of a drive bevel gear 12. Vertical rods 16 are rotatably connected to the left and right sides inside the water supply tank 1. A driven bevel gear 11 is fixedly connected to the middle of the outer wall of the vertical rod 16. The driven bevel gear 11 is connected to the drive bevel gear 12. A baffle plate 15 is fixedly connected to the top of the rod 16. Storage tanks 26 are installed on both the left and right sides of the top of the water supply tank 1. A fixed plate 17 is fixedly connected to the inner bottom wall of the storage tank 26. A stirring blade 10 is fixedly connected to the end of the rod 16. A prompting mechanism 2 is installed on the outside of the water supply tank 1 to indicate the residual chlorine content in the storage tank 26 to the staff. A knob 5 is located on the top left side of the external frame 3, and a fixing block 2 4 is fixedly connected to the top of the knob 5. A slot 13 is opened on the front side of the drive pulley 21, and both fixing blocks 1 20 and 2 4 engage with the slot 13. A chlorination pump 24 is installed on the top rear side of the water supply tank 1. An inlet pipe 23 is connected to the input end of the chlorination pump 24, and a sealing ring 25 is installed on the outside of the rubber belt 205. A drain pipe 22 is connected to the output end of the chlorination pump 24, and the end of the drain pipe 22 is connected to the top of the storage tank 26.

[0041] Specifically, during the chlorination treatment of secondary water supply, the chlorination pump 24 should be started to drive the inlet pipe 23 to introduce chlorine into the system, and the chlorine should be transported to the storage tank 26 through the drain pipe 22; the sealing ring 25 must ensure the sealing of the opening; at the same time, the drive motor 19 should be started to rotate the fixed block 20; the engagement of the fixed block 20 with the slot 13, and the synchronous rotation of the drive pulley 21, drive the driven pulley 18 to rotate accordingly through the connecting belt 14, so that the two drive bevel gears 12 will also rotate synchronously. The drive motor 19 rotates and meshes with the driven bevel gear 11, thereby driving the driven bevel gear 11, baffle 15 and stirring blade 10 to rotate synchronously; the rotation of baffle 15 will open the groove on the fixed plate 17, allowing chlorine to be released into the water supply tank 1; the rotation of stirring blade 10 ensures that water and chlorine are fully mixed, thereby improving water purification efficiency; if the system malfunctions or there is a power outage, the drive motor 19 should be removed and the fixed block 2 4 should be engaged with the slot 13, and the other structures should be driven by rotating the knob 5 to ensure that the normal water use of residents is not affected.

[0042] Reference Figure 3 and Figure 4The prompting mechanism 2 includes a float 201, which is located inside the liquid storage tank 26. A rubber belt 205 is fixedly connected to the outside of the float 201, and a ball 204 is installed at the end of the rubber belt 205. Inclined drawers 202 are fixedly connected to the left and right sides of the outer wall of the water supply tank 1. Hollow columns 203 are fixedly connected to the left and right sides of the water supply tank 1. Copper drums 206 are installed on the left and right sides of the bottom of the water supply tank 1.

[0043] Specifically, when the chlorine content in the storage tank 26 is low, the drop in water level will cause the float 201 to drop synchronously, thereby stretching the rubber belt 205; when the water level drops to the preset warning level, the rubber belt 205 breaks due to the force, causing the ball 204 to slide into the inclined drawer 202 and further fall into the hollow column 203, and finally fall freely onto the bronze drum 206; the bronze drum 206 makes a loud sound after being hit, thereby alerting the staff to the chlorine content status.

[0044] Reference Figure 1 The bottom wall of the water supply tank 1 is connected by multiple arc-shaped pipes 9 at equal intervals, and valves 8 are installed on the outside of the arc-shaped pipes 9; an observation window 7 is installed on the front side of the water supply tank 1, and the observation window 7 is threadedly connected to the water supply tank 1 by bolts 6.

[0045] Specifically, the purified water is discharged through the arc-shaped pipe 9, the opening and closing of the arc-shaped pipe 9 can be controlled by the valve 8, and the observation window 7 can be opened and closed by the bolt 6. The water level can be observed through the observation window 7.

[0046] Working principle: When adding chlorine to the secondary water supply, the chlorination pump 24 is turned on to drive the inlet pipe 23 to draw in chlorine, while the chlorine is discharged into the storage tank 26 through the drain pipe 22. At the same time, the sealing ring 25 seals the opening. Simultaneously, the drive motor 19 is turned on to drive the fixed block 20 to rotate. The engagement of the fixed block 20 with the slot 13 causes the drive pulley 21 to rotate synchronously. The rotation of the drive pulley 21 is linked to the driven pulley 18 through the connecting belt 14, thereby causing the two drive bevel gears 12 to rotate synchronously. The rotation of the active bevel gear 12 meshes with the driven bevel gear 11, thereby driving the driven bevel gear 11, the baffle 15 and the stirring blade 10 to rotate synchronously. The rotation of the baffle 15 opens the groove on its corresponding fixed plate 17, allowing chlorine to leak into the water supply tank 1. The rotation of the stirring blade 10 thoroughly mixes the water and chlorine, accelerating the water purification efficiency. In case of system failure or power outage, the drive motor 19 can be removed, and the fixed block 4 can be engaged with the slot 13. The rotation of the knob 5 can then drive the transmission of other structures.

[0047] Furthermore, when the chlorine level in the storage tank 26 is low, the float 201 descends synchronously with the water level, thereby pulling the rubber belt 205 to extend. When the water level reaches the preset warning position, the rubber belt 205 snaps under force, causing the ball 204 to fall into the inclined drawer 202 and slide. At the same time, it falls into the hollow column 203 and falls freely onto the bronze drum 206. The bronze drum 206 makes a loud noise under the force, thus alerting the staff to the chlorine level in the bronze drum 206.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
