Description

Technical Field

[0001] This invention relates to the field of folded plate installation technology, and in particular to a folded plate installation construction device for a large-scale flocculation horizontal flow sedimentation tank in a water purification plant. Background Technology

[0002] As a key component in flocculation tanks, folding plates create numerous small vortices by causing water to flow in a zigzag pattern between plates of the same type or between plates of different types, effectively improving the collision effect between particulate matter and flocculant in the raw water. The installation and construction of folding plates has always been a crucial step in the construction of water treatment plants.

[0003] A search revealed Chinese patent CN117446937A, which discloses a method for installing folded plates in a large-scale flocculation sedimentation tank of a water purification plant. The method includes the following steps: Step S1: Prefabricate assembled folded plates at the manufacturing plant according to the drawings; Step S2: Mark out the site according to the drawings; Step S3: Excavate the earthwork according to the drawings, and then manually trim it; Step S4: Construct the steel reinforcement structure of the walls of the flocculation sedimentation tank, and reserve steel rebar ends for connection with the assembled folded plates; Step S5: Construct the formwork for pouring the walls of the flocculation sedimentation tank; Step S6: Use a pump truck to pour cement concrete into the formwork for pouring the walls of the flocculation sedimentation tank, and remove the formwork after the cement concrete has solidified; Step S7: Use a hoisting mechanism to hoist the assembled folded plates into the flocculation sedimentation tank and install the assembled folded plates; Step S8: Use a grouting pressure tank to inject grouting liquid into the cavity of the assembled folded plates.

[0004] Based on the above search results and existing technologies, the following findings were made:

[0005] There are two existing methods for fixing folding plates: one is to use angle steel and expansion bolts to fix the folding plate to the pool wall or partition; the other is to use a simple snap-fit ​​structure to snap the folding plate to the partition or bracket inside the pool. For the bolt connection method, the installation process is relatively cumbersome. Installers need to drill expansion bolts on the front of the folding plate for fixing, and each installation point requires multiple steps such as drilling, driving in expansion bolts, and tightening, resulting in low construction efficiency. For the snap-fit ​​connection method, the fixing method is relatively simple, usually only using claws or slots for simple snap-fit ​​positioning. This fixing structure lacks an effective locking and anti-loosening mechanism. Under long-term water flow impact and hydraulic load, the snap-fit ​​connection is prone to loosening, causing the folding plate to shift or vibrate, seriously affecting the installation stability of the folding plate. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention proposes a folding plate installation and construction device for a large-scale water purification plant flocculation horizontal flow sedimentation tank. Through a dual locking method of hydraulically driven pins and mechanically clamped connecting rods, the installation stability of the folding plate body is significantly improved, effectively preventing it from loosening or falling off during operation.

[0007] The technical solution for achieving the purpose of this invention is: a baffle plate installation and construction device for a large-scale water purification plant flocculation horizontal flow sedimentation tank, comprising a sedimentation tank, wherein a baffle plate is fixedly connected to the inner wall of the sedimentation tank, and multiple sliding frames are slidably connected to the baffle plate, and further comprising:

[0008] A fixing mechanism, which is located on the sliding frame;

[0009] The fixing mechanism includes a fixing unit, a pressing unit, and a driving unit. The fixing unit includes multiple fixing rods fixedly connected to each sliding frame. A folding plate body is slidably sleeved on each fixing rod. A fixing cylinder is fixedly connected to each sliding frame, and a sliding piston rod is slidably connected to the fixing cylinder. The bottom end of the sliding piston rod contacts a partition plate. Two fixing tubes are fixedly connected to the fixing cylinder, and both fixing tubes are fixedly connected to the sliding frame. Channel grooves are formed on each of the fixing rods, and two water channels are formed inside the sliding frame. The multiple channel grooves are respectively connected to the two water channels. One end of each water trough is connected to two fixed pipes. Each fixed rod is slidably connected to a pin. Each folding plate body has a slot, and the top of the pin extends into the slot. Each sliding frame is fixedly connected to two fixed seats. Each fixed seat is slidably connected to a sliding rod. Each folding plate body is fixedly connected to a locking block. Each locking block has a locking groove. Each row of locking grooves has a common connecting rod. The connecting rod is fixedly connected to one end of the sliding rod. The other end of the sliding rod is fixedly connected to a cylindrical rod. Multiple bent rods are fixedly connected to the partition plate. The cylindrical rod and the bent rod are in contact.

[0010] In some embodiments, the drive unit includes two fixed sleeves fixedly connected to the sedimentation tank, a movable frame slidably connected to the two fixed sleeves, a fixed block fixedly connected to the movable frame, a mounting base fixedly connected to the sedimentation tank, a servo motor fixedly connected to the mounting base, a threaded rod fixedly connected to the output end of the servo motor, and the fixed block screwed onto the threaded rod.

[0011] In some embodiments, each of the pins is fitted with a return spring, the two ends of which are fixedly connected to the pin and the fixing rod, respectively.

[0012] In some embodiments, each of the sliding piston rods is fitted with a compression spring, the two ends of which are fixedly connected to the fixed cylinder and the sliding piston rod, respectively.

[0013] In some embodiments, each of the sliding rods is fitted with a connecting spring, the two ends of which are fixedly connected to the sliding rod and the fixed base, respectively.

[0014] In some embodiments, each of the folding plate bodies has a movable groove, and a movable plate is slidably connected in the movable groove. The top end of the movable plate is in contact with the folding plate body. Each of the movable grooves is provided with a telescopic spring, and the two ends of the telescopic spring are in contact with the folding plate body and the movable plate, respectively.

[0015] In some embodiments, the movable plate is made of rubber.

[0016] In some embodiments, two mounting blocks are fixedly connected to the sedimentation tank, and the threaded rod is rotatably connected to the two mounting blocks.

[0017] In some embodiments, a protective plate is fixedly connected to both mounting blocks, and the protective plate is made of plastic.

[0018] The significant advantages of this invention compared to existing technologies are:

[0019] Firstly, this invention, through the setting of a fixing unit, after replacing the folding plate body to be replaced, starts the servo motor to drive the threaded rod to rotate in the opposite direction. The rotation of the threaded rod drives the sliding frame to reset. When the sliding piston rod contacts the partition, it causes the sliding piston rod to enter the fixing cylinder, squeezing the oil in the fixing cylinder into the channel groove. This causes the oil to drive the pin into the slot. At the same time, the bending rod drives the cylindrical rod and the connecting rod to move, causing the connecting rod to enter the slot. This achieves double fixing of the folding plate body and improves the fixing effect of the folding plate body.

[0020] Secondly, the present invention uses a drive unit to drive a servo motor to rotate a threaded rod. The rotation of the threaded rod causes the fixed block, movable frame, and sliding frame to move upward. The movement of the sliding frame causes the fixed rod and the folding plate body to move until the folding plate body is removed from the sedimentation tank. This realizes the lifting and lowering of the folding plate body, which facilitates the installation of the folding plate body.

[0021] Thirdly, the telescopic spring of the present invention presses the movable plate onto the folding plate body. Since the movable plate is made of rubber, the friction between the movable plate and the folding plate body is increased, thereby improving the stability of the folding plate body.

[0022] This solves the problems of existing snap-fit ​​connections being too simple, prone to loosening, and having poor stability. Attached Figure Description

[0033] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] This invention provides an improved installation and construction device for baffle plates in a large-scale water purification plant's flocculation and horizontal flow sedimentation tank. The technical solution of this invention is as follows:

[0035] like Figures 1-7 As shown, a folding plate installation construction device for a large-scale water purification plant flocculation horizontal flow sedimentation tank includes a sedimentation tank 1, with a partition plate 11 fixedly connected to the inner wall of the sedimentation tank 1, and multiple sliding frames 12 slidably connected to the partition plate 11. The device also includes:

[0036] A fixing mechanism is located on the sliding frame 12;

[0037] The fixing mechanism includes a fixing unit, a pressing unit, and a driving unit. The fixing unit includes multiple fixing rods 13 respectively fixedly connected to each sliding frame 12. A folding plate body 14 is slidably sleeved on each fixing rod 13. A fixing cylinder 15 is fixedly connected to each sliding frame 12. A sliding piston rod 16 is slidably connected to the fixing cylinder 15. The bottom end of the sliding piston rod 16 contacts the partition plate 11. Two fixing tubes 18 are fixedly connected to the fixing cylinder 15. Both fixing tubes 18 are fixedly connected to the sliding frame 12. Each fixing rod 13 has a channel groove 2. Two water passage grooves 19 are opened inside the sliding frame 12. The multiple channel grooves 2 are respectively connected to the two water passage grooves 19. One end of each water passage groove 19 is respectively connected to the two fixing tubes 18. A pin 21 is slidably connected to each fixing rod 13. A slot is opened on each folding plate body 14. The top end of the pin 21 extends into the slot. Two fixing seats 5 are fixedly connected to each sliding frame 12. A sliding rod is slidably connected to each fixing seat 5. 51. Each folding plate body 14 is fixedly connected to a locking block 56, and each locking block 56 has a locking slot 57. Each row of locking slots 57 has a common connecting rod 55. The connecting rod 55 is fixedly connected to one end of the sliding rod 51, and the other end of the sliding rod 51 is fixedly connected to a cylindrical rod 52. Multiple bent rods 53 are fixedly connected to the partition plate 11, and the cylindrical rod 52 is in contact with the bent rod 53. Through the setting of the fixing unit, after the folding plate body 14 to be replaced is installed, the servo motor 44 is started to drive the threaded rod. 45 rotates in the opposite direction, and the threaded rod 45 rotates to drive the sliding frame 12 to reset. When the sliding piston rod 16 contacts the partition plate 11, the sliding piston rod 16 enters the fixed cylinder 15, squeezing the oil in the fixed cylinder 15 into the channel groove 2, so that the oil drives the pin 21 into the slot. At the same time, the bending rod 53 drives the cylindrical rod 52 and the connecting rod 55 to move, so that the connecting rod 55 enters the slot 57, realizing the double fixation of the folding plate body 14 and improving the fixation effect of the folding plate body 14.

[0038] like Figure 5 As shown, in one embodiment, the drive unit includes two fixed sleeves 4 fixedly connected to the sedimentation tank 1. A movable frame 41 is slidably connected to both fixed sleeves 4. A fixed block 42 is fixedly connected to the movable frame 41. A mounting base 43 is fixedly connected to the sedimentation tank 1. A servo motor 44 is fixedly connected to the mounting base 43. A threaded rod 45 is fixedly connected to the output end of the servo motor 44. The fixed block 42 is screwed onto the threaded rod 45. Through the setting of the drive unit, the servo motor 44 drives the threaded rod 45 to rotate. The rotation of the threaded rod 45 drives the fixed block 42, the movable frame 41 and the sliding frame 12 to move upward. The movement of the sliding frame 12 drives the fixed rod 13 and the folding plate body 14 to move until the folding plate body 14 moves out of the sedimentation tank 1, thereby realizing the lifting and lowering of the folding plate body 14, which facilitates the installation of the folding plate body 14.

[0039] like Figure 4 As shown, in one embodiment, each pin 21 is fitted with a return spring 22, and the two ends of the return spring 22 are fixedly connected to the pin 21 and the fixing rod 13 respectively. With the setting of the return spring 22, when the oil in the channel groove 2 is drawn back into the fixing cylinder 15, the return spring 22 can drive the pin 21 to reset, thereby realizing the automatic reset of the pin 21.

[0040] like Figure 3 As shown, in one embodiment, in order to enable the sliding piston rod 16 to automatically reset, each sliding piston rod 16 is fitted with a compression spring 17, and the two ends of the compression spring 17 are fixedly connected to the fixed cylinder 15 and the sliding piston rod 16 respectively.

[0041] like Figure 7 As shown, in one embodiment, in order to enable the sliding rod 51 to automatically reset, each sliding rod 51 is fitted with a connecting spring 54, and the two ends of the connecting spring 54 are fixedly connected to the sliding rod 51 and the fixed seat 5, respectively.

[0042] like Figure 4 As shown, in one embodiment, each folding plate body 14 has a movable groove 3, and a movable plate 31 is slidably connected in the movable groove 3. The top end of the movable plate 31 is in contact with the folding plate body 14. Each movable groove 3 is provided with a telescopic spring 32, and the two ends of the telescopic spring 32 are in contact with the folding plate body 14 and the movable plate 31, respectively. The movable plate 31 is made of rubber. Through the setting of the movable plate 31, the telescopic spring 32 presses the movable plate 31 onto the folding plate body 14. Since the movable plate 31 is made of rubber, the friction between the movable plate 31 and the folding plate body 14 is increased, thereby improving the stability of the folding plate body 14.

[0043] like Figure 1 As shown, in one embodiment, two mounting blocks 46 are fixedly connected to the sedimentation tank 1, and the threaded rod 45 is rotatably connected to the two mounting blocks 46; the installation of the mounting blocks 46 improves the stability of the threaded rod 45.

[0044] like Figure 2 As shown, in one embodiment, a protective plate 47 is fixedly connected to both mounting blocks 46. The protective plate 47 is made of plastic. The protective plate 47 is used to protect the threaded rod 45.

[0045] The specific working method is as follows: The servo motor 44 is started to drive the threaded rod 45 to rotate. The rotation of the threaded rod 45 drives the fixed block 42 to move upward. The movement of the fixed block 42 drives the movable frame 41 and the sliding frame 12 to move upward. The movement of the sliding frame 12 drives the fixed rod 13 and the folding plate body 14 to move. Since the compression spring 17 is in a compressed state, the compression spring 17 drives the sliding piston rod 16 to reset. The sliding piston rod 16 draws the oil in the channel groove 2 into the fixed cylinder 15 through the water channel 19 and the fixed pipe 18. Since the reset spring 22 is in a compressed state, the reset spring 22 drives the pin 21 to reset and move away from the slot. The upward movement of the sliding frame 12 drives the fixed seat 5 to move. The movement of the fixed seat 5 drives the sliding rod 51 and the cylindrical rod 52 to move, so that the cylindrical rod 52 moves away from the bent rod 53. Since the connecting spring 54 is in a stretched state, the connecting spring 54 drives the sliding rod 51 to reset. The reset of the sliding rod 51 drives the connecting rod 55 away from the slot 5. 7. At this point, the automatic release of all fixing effects on the folding plate body 14 is achieved until the folding plate body 14 is removed from the sedimentation tank 1. The folding plate body 14 that needs to be processed is removed and replaced with the folding plate body 14 to be replaced. The telescopic spring 32 presses the movable plate 31 onto the folding plate body 14. Since the movable plate 31 is made of rubber, the friction between the movable plate 31 and the folding plate body 14 is increased, which improves the stability of the folding plate body 14. The servo motor 44 is started to drive the threaded rod 45 to rotate in the opposite direction. The rotation of the threaded rod 45 drives the sliding frame 12 to reset. When the sliding piston rod 16 contacts the partition plate 11, the sliding piston rod 16 enters the fixed cylinder 15, squeezing the oil in the fixed cylinder 15 into the channel groove 2. The oil drives the pin 21 into the slot. At the same time, the bending rod 53 drives the cylindrical rod 52 and the connecting rod 55 to move, so that the connecting rod 55 enters the slot 57. This achieves double fixing of the folding plate body 14 and improves the fixing effect of the folding plate body 14.

[0046] The technical means disclosed in this invention are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this invention are common knowledge to those skilled in the art.
