Description

Technical Field

[0001] This utility model relates to the field of water conservancy construction technology, specifically to a water conservancy construction diversion device. Background Technology

[0002] In water conservancy construction, diversion operations are frequently required to guide river water or groundwater to specific areas or bypass construction areas. During this process, the water flow often carries a large amount of impurities such as silt, gravel, and aquatic plants. If these impurities directly enter the diversion pipes or pumping equipment, they can easily cause blockages, severely affecting construction efficiency and even potentially damaging the equipment.

[0003] Patent application number 202420578839.2 discloses a diversion device for water conservancy construction, including a diversion box with an open upper end. A water outlet pipe, identical to the one inside the diversion box, is located at the lower front end of the diversion box. Two sliding grooves are formed on both the left and right inner walls of the diversion box, and a filter mechanism is detachably installed inside the diversion box via four sliding grooves. This water diversion device for water conservancy construction utilizes two filter screens to improve filtration efficiency, prevent foreign objects from entering the water outlet pipe and causing blockage, improve performance, and extend the equipment's service life. A threaded connection between a screw and a cleaning plate allows the cleaning plate to move back and forth on the upper end of the filter plate. A cleaning brush cleans the filter screen, preventing foreign objects from clogging it and affecting its filtration effect. It is highly practical. Furthermore, the filter mechanism can be removed from the diversion box by lifting a handle, facilitating the cleaning of foreign objects accumulated on the upper part of the filter plate.

[0004] The device has some shortcomings in use. For example, under conditions with high impurity content, the filter screen will be clogged quickly, requiring frequent shutdowns for manual cleaning. This not only increases the labor intensity of workers, but also interrupts the flow diversion operation and delays the construction period. In addition, the device lacks an effective clogging early warning mechanism. Operators often only discover the fault after the water flow rate has decreased significantly, resulting in a delayed response that is difficult to meet people's needs. Utility Model Content

[0005] The purpose of this utility model is to provide a diversion device for water conservancy construction to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A hydraulic construction diversion device includes an upper partition plate fixedly installed inside a housing. A filter plate assembly is installed at the bottom of the upper partition plate. The interior of the housing is divided into an outlet chamber and a sedimentation and filtration chamber by the upper partition plate and the filter plate assembly. An output pipe is fixedly installed on the left side of the housing and connects to the interior of the outlet chamber. An inlet pipe is fixedly installed on the right side of the housing and connects to the interior of the sedimentation and filtration chamber. A cover is detachably installed at the opening on the upper surface of the housing. A pressure block is fixedly connected to the bottom surface of the cover and snaps into the interior of the housing. A transmission block is fixedly installed on the bottom surface of the pressure block and is located inside the outlet chamber. A transmission cavity is opened inside the transmission block. A connecting shaft is rotatably installed inside the lower part of the transmission cavity. Both ends of the connecting shaft extend into the interior of the outlet chamber. Multiple springs are installed on the upper and lower surfaces of both ends of the connecting shaft. A striking ball is installed on one end of each spring for striking the filter plate assembly. A slag discharge trough is opened at the bottom of the front of the housing. A cleaning baffle is detachably installed on the front of the housing for sealing the slag discharge trough.

[0008] Preferably, the filter plate assembly includes a mounting frame, with support blocks fixedly installed on the inner walls of the front and rear sides of the housing. The mounting frame is slidably disposed inside the water outlet chamber and abuts against the support blocks. A filter screen is fixedly installed inside the mounting frame. The water outlet chamber and the sedimentation filter chamber are connected by the filter screen. Two handles are fixedly installed on the upper surface of the mounting frame, with the top of the handles abutting against the pressure block.

[0009] Preferably, the connection between the inlet pipe and the housing is higher than the connection between the outlet pipe and the housing, and the outlet pipe is positioned above the filter screen.

[0010] Preferably, a motor is fixedly installed on the upper surface of the housing, and an output shaft is fixedly connected to the output end of the motor. One end of the output shaft extends into the transmission cavity and is fixedly installed with a second bevel gear. A first bevel gear is sleeved on the outer surface of the connecting shaft, and the second bevel gear meshes with the first bevel gear.

[0011] Preferably, a sealing block is fixedly installed on one side of the cleaning baffle, and a sealing ring is fitted on the outer surface of the sealing block. The sealing block and the sealing ring are snapped into the inside of the sealing groove. Multiple bolts are screwed onto the surface of the cleaning baffle, and the cleaning baffle is installed on the front of the box by bolts.

The first water level sensor is higher than the second water level sensor but lower than the inlet pipe. The second water level sensor is aligned with the outlet pipe. An alarm light is fixedly installed on the front of the housing. The alarm light is electrically connected to both the first and second water level sensors. When the water level inside the sedimentation and filtration chamber is higher than the first water level sensor and the water level inside the outlet chamber is lower than the second water level sensor, it indicates that there are a large number of impurities inside the sedimentation and filtration chamber, which need to be cleaned, and the alarm light will sound an alarm.

[0023] Please see Figure 1-5A water diversion device for hydraulic construction includes a housing 1 with an upper partition 2 fixedly installed inside. A filter plate assembly is installed at the bottom of the upper partition 2. The interior of the housing 1 is divided into an outlet chamber 6 and a sedimentation and filtration chamber 7 by the upper partition 2 and the filter plate assembly. An output pipe is fixedly installed on the left side of the housing 1 and communicates with the interior of the outlet chamber 6. An inlet pipe is fixedly installed on the right side of the housing 1 and communicates with the interior of the sedimentation and filtration chamber 7. The filter plate assembly includes a mounting frame 3. Support blocks are fixedly installed on the inner walls of the front and rear sides of the housing 1. The mounting frame 3 is slidably disposed inside the outlet chamber 6 and abuts against the support blocks. The interior of the mounting frame 3 is fixedly installed with... There is a filter screen 4. The water outlet chamber 6 and the sedimentation filter chamber 7 are connected by the filter screen 4. The connection between the water inlet pipe and the tank body 1 is higher than the connection between the water outlet pipe and the tank body 1. The water outlet pipe is set above the filter screen 4. The construction guide water flows into the sedimentation filter chamber 7 from the water inlet pipe on the right. Since the water inlet is higher than the water outlet, the water flow stays briefly in the sedimentation filter chamber 7. Some large particles of impurities settle to the bottom of the tank under the action of gravity. Then, the water flow passes through the filter screen 4 under the action of pressure and enters the water outlet chamber 6. The filter screen 4 intercepts most of the suspended particles, aquatic plants and other impurities in the water. The clean water finally flows out from the output pipe.

[0024] A cover 8 is detachably installed at the opening on the upper surface of the box 1. A pressure block 9 is fixedly connected to the bottom surface of the cover 8. The pressure block 9 is snapped into the inside of the box 1. Two handles 5 are fixedly installed on the upper surface of the mounting frame 3. The top of the handles 5 abuts against the pressure block 9. Through the cooperation of the pressure block 9 and the support block, the mounting frame 3 can be easily fixed inside the box 1 to reduce its shaking.

[0025] A transmission block 11 is fixedly installed on the bottom surface of the pressure block 9. The transmission block 11 is located inside the water outlet cavity 6. A transmission cavity 12 is opened inside the transmission block 11. A connecting shaft 13 is rotatably installed inside the lower part of the transmission cavity 12. Both ends of the connecting shaft 13 extend into the water outlet cavity 6. Multiple springs 17 are installed on the upper and lower surfaces of both ends of the connecting shaft 13. A striking ball 18 is installed on one end of each spring 17 for striking the filter plate assembly. A motor 10 is fixedly installed on the upper surface of the housing 1. An output shaft 16 is fixedly connected to the output end of the motor 10. One end of the output shaft 16 extends into the transmission cavity 12 and is fixedly installed with a second bevel gear 15. A first bevel gear 14 is sleeved on the outer surface of the connecting shaft 13. The second bevel gear 15 meshes with the first bevel gear 14.

[0026] During equipment operation, motor 10 works continuously or intermittently, driving the connecting shaft 13 to rotate through bevel gear set. The striking ball 18 installed on the connecting shaft 13 is thrown outward under the action of centrifugal force, while stretching spring 17. The striking ball 18 will periodically and frequently strike the upper surface of filter screen 4, causing filter screen 4 to vibrate. This continuous vibration and striking can effectively shake off the impurities attached to filter screen 4, causing them to fall back to the bottom of sedimentation filter chamber 7, thereby greatly slowing down the clogging speed of filter screen and realizing automatic clogging function.

[0027] A slag discharge trough is provided at the bottom front of the housing 1. A cleaning baffle 21 is detachably installed on the front of the housing 1 to seal the slag discharge trough. A sealing block is fixedly installed on one side of the cleaning baffle 21. A sealing ring is fitted on the outer surface of the sealing block. The sealing block and the sealing ring are snapped into the inside of the sealing trough to ensure sealing. Multiple bolts are screwed onto the surface of the cleaning baffle 21. The cleaning baffle 21 is installed on the front of the housing 1 by bolts. By removing the bolts, the cleaning baffle 21 can be removed from the housing 1 to facilitate the discharge and cleaning of impurities inside the sedimentation and filtration chamber 7 through the slag discharge trough.

[0028] See Figure 2 A water level sensor 20 is fixedly installed on the left side of the upper partition 2. The water level sensor 20 is located inside the outlet chamber 6. A water level sensor 19 is fixedly installed on the right side of the upper partition 2. The water level sensor 19 is located inside the sedimentation and filtration chamber 7. The water level sensor 19 is higher than the water level sensor 20 but lower than the inlet pipe. The water level sensor 20 is aligned with the outlet pipe. An alarm light 22 is fixedly installed on the front of the housing 1. The alarm light 22 is electrically connected to both the water level sensor 19 and the water level sensor 20. When the water level inside the sedimentation and filtration chamber 7 is higher than the water level sensor 19 and the water level inside the outlet chamber 6 is lower than the water level sensor 20, it indicates that there are a lot of impurities inside the sedimentation and filtration chamber 7 and it needs to be cleaned. The alarm light 22 will sound an alarm.

[0029] The water level monitoring system monitors the water levels in the two chambers in real time. Under normal circumstances, the water levels in the two chambers are basically the same. When the filter screen 4 starts to get clogged due to too many impurities, the resistance to water flow increases, causing the water level in the sedimentation filter chamber 7 to rise and the water level in the outlet chamber 6 to drop. Once the water level sensor 19 is submerged (the water level in the sedimentation chamber is too high) and the water level sensor 20 is exposed to the air (the water level in the outlet chamber is too low), the control system will determine that there is a serious blockage and light up the alarm light 22 to remind the staff to clean it. At this time, the cleaning baffle 21 on the front can be opened to completely remove the impurities deposited at the bottom of the tank from the slag discharge trough.

[0030] Working principle: In this water conservancy construction diversion device, the construction diversion water flows into the sedimentation and filtration chamber 7 from the inlet pipe on the right side. Since the inlet is higher than the outlet, the water flow stays briefly in the sedimentation and filtration chamber 7. Some large particles of impurities settle to the bottom of the chamber under the action of gravity. Subsequently, the water flows through the filter screen 4 under the action of pressure and enters the outlet chamber 6. The filter screen 4 intercepts most of the suspended particles, aquatic plants and other impurities in the water. The clean water finally flows out from the outlet pipe.

[0031] During equipment operation, motor 10 works continuously or intermittently, driving the connecting shaft 13 to rotate through bevel gear set. The striking ball 18 installed on the connecting shaft 13 is thrown outward under the action of centrifugal force, while stretching spring 17. The striking ball 18 will periodically and frequently strike the upper surface of filter screen 4, causing filter screen 4 to vibrate. This continuous vibration and striking can effectively shake off the impurities attached to filter screen 4, causing them to fall back to the bottom of sedimentation filter chamber 7, thereby greatly slowing down the clogging speed of filter screen and realizing automatic clogging function.

[0032] The water level monitoring system monitors the water level of the two chambers in real time. Under normal circumstances, the water levels of the two chambers are basically the same. When the filter screen 4 starts to get clogged due to too many impurities, the resistance to water flow increases, causing the water level in the sedimentation filter chamber 7 to rise and the water level in the outlet chamber 6 to drop. Once the water level sensor 19 is submerged (the water level in the sedimentation chamber is too high) and the water level sensor 20 is exposed to the air (the water level in the outlet chamber is too low), the control system will determine that there is a serious blockage and light up the alarm light 22 to remind the staff to clean it. At this time, the cleaning baffle 21 on the front can be opened to completely remove the impurities deposited at the bottom of the tank from the slag discharge trough.

[0033] For deep cleaning or filter replacement, open the cover 8 and use the handle 5 to lift out the entire filter plate assembly for cleaning.
