Description

Technical Field

[0001] This utility model relates to the field of flushing door technology, specifically a flushing door suitable for high water head. Background Technology

[0002] A flushing gate typically consists of a door frame, door body, seals, a hydraulic drive system, and an intelligent control system. For example, in a rainwater storage tank, the flushing gate is installed on the partition wall between the storage chamber and the corridor, and is normally kept closed. When cleaning is required, the hydraulic device is activated via the PLC control system, instantly opening the gate. The water level difference between the storage chamber and the corridor creates a high-speed water flow, similar to a dam releasing floodwater, flushing away sediment at the bottom of the tank.

[0003] Existing flushing gates on the market typically operate at water pressures below 2m. When the water pressure exceeds 2m, issues such as deformation and damage to the bottom hooks and locking mechanisms can easily occur. Furthermore, the connecting rods are generally made by welding, which makes them prone to deformation, resulting in high labor costs and long processing cycles.

[0004] Therefore, a solution is needed. Utility Model Content

[0012] (III) Beneficial Effects

[0013] This invention provides a flushing door suitable for high water head applications. It offers the following advantages:

[0014] This solution features an adjustable locking hook at the bottom of a high-water-head flushing door. The structure, utilizing an adjusting bolt inserted through a bolt hole and secured with a nut, flexibly adapts to locking requirements under high water heads, preventing stress concentration. The locking hook seat, through a movable connection design between the lower and upper clamping plates, the rotating column, and the locking seat, disperses the force of high water pressure, preventing rigid deformation and enabling the flushing door to be stably used in scenarios with water pressure exceeding 2m. The locking linkage adopts a hollow rectangular non-welded structure, reducing weight, increasing strength to lower the probability of deformation, and facilitating assembly with other components via a square opening, through-hole, connecting rod square sleeve, and drive pin. This replaces welding processes, reducing labor costs and shortening the processing cycle. The hydraulic cylinder of the drive unit is securely installed via a hydraulic seat and locking bolt. The fork-shaped joint, in conjunction with the joint pin, stably transmits force. The L-shaped connecting rod of the transmission unit is movably connected to the connecting rod seat via a rotating shaft, with the fork-shaped joint and connecting rod square sleeve hinged at both ends. This ensures smooth transmission and low power loss, reliably driving the locking linkage under high-water-head conditions and guaranteeing stable operation of the locking mechanism. In summary, this solution comprehensively addresses the shortcomings of existing technologies and significantly improves the reliability, practicality, and processing economy of flushing doors in high-water-head scenarios.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figure 1-6 This utility model provides a technical solution:

[0024] Example 1

[0025] To address the aforementioned issues: existing flushing doors on the market typically operate at water pressures below 2m. When the water pressure exceeds 2m, the bottom hooks and locking mechanisms are prone to deformation and damage. Furthermore, the connecting rods are generally welded, making them susceptible to deformation, resulting in high labor costs and long processing cycles.

[0026] The solution is as follows: A flushing door suitable for high water head includes a door frame assembly 1. A door panel rotating hinge bracket 4 is installed at the top of the door frame assembly 1, and a door panel rotating hinge assembly 3 is installed at the end of the door panel rotating hinge bracket 4. A door panel assembly 2 is movably connected to the door frame assembly 1 via the door panel rotating hinge assembly 3. A drive device 14 and a transmission device 15 are installed on the right side of the door frame assembly 1. One end of the drive device 14 and the transmission device 15 are connected. The bottom of the door panel assembly 2 has several sets of adjustable locking hooks 16 arranged horizontally at equal intervals. The bottom of the door frame assembly 1 also has several sets of locking hook seats 17 arranged horizontally at equal intervals. A locking link 18 is installed between the several sets of adjustable locking hooks 16 and the locking hook seats 17. The right end of the locking link 18 is connected to the other end of the transmission device 15. The adjustable locking hook 16 includes a welding block 19. The locking hook plate 20 and the fixed locking hook 21 are provided. A set of bolt holes 23 are opened on the surface of the welding block 19. The locking hook plate 20 is located inside the welding block 19. A set of adjusting bolts 22 are provided at the rear end of the locking hook plate 20. The set of adjusting bolts 22 passes through the set of bolt holes 23 and is fixed by nuts. The fixed locking hook 21 is welded to the inner end of the locking hook plate 20. The locking hook seat 17 includes a locking seat 24, a lower clamping plate 25, and an upper clamping plate 26. The lower clamping plate 25 is located above the upper clamping plate 26. A first connecting post 27, a rotating post 28, and a second connecting post 29 are respectively provided between the lower clamping plate 25 and the upper clamping plate 26. The first connecting post 27 is located at the front end of the second connecting post 29. The second connecting post 29 is located at the front end of the rotating post 28. The second connecting post 29 passes through the locking connecting rod 18. The lower clamping plate 25 and the upper clamping plate 26 are movably connected to the locking seat 24 through the rotating post 28.

[0027] Analysis of the above content: Door panel assembly 2 forms a movable hinge with door frame assembly 1 through door panel rotating hinge assembly 3 (installed on door panel rotating hinge bracket 4 fixed at the top of door frame assembly 1), providing support for the rotation and opening / closing of the door panel. When the drive device 14 drives the bottom latch to release, door panel assembly 2 can rotate around door panel rotating hinge assembly 3 to open; when locked, door panel assembly 2 fits against door frame to achieve a seal. Adjusting bolt 22 passes through bolt hole 23 on the surface of welding block 19, and the position of lock hook plate 20 is fixed by nut, thereby adjusting the fitting clearance between fixed lock hook 21 and lock hook seat 17. The adjustable design allows the lock hook to adapt to... To prevent locking failure or excessive wear due to improper clearance under different high water head conditions and improve locking reliability under high water pressure, the lower clamping plate 25 and the upper clamping plate 26 are movably connected to the locking seat 24 via the rotating column 28. The second connecting column 29 passes through the locking connecting rod 18, allowing the locking seat 24 to rotate around the rotating column 28. When the high water head water flow impacts the door panel, or when the locking connecting rod 18 drives the locking hook seat to move, the locking seat 24 can buffer the force by rotating around the rotating column 28. The movably connected rotating column 28 can disperse the water pressure and mechanical transmission stress under high water head, prevent rigid deformation of the locking hook seat, and enhance the structural durability under high water head.

[0028] Example 2:

[0029] Please see Figure 1-6 This utility model provides a technical solution based on Embodiment 1: the locking link 18 has a rectangular structure and a hollow structure inside. The surface of the locking link 18 has several sets of square openings 30 distributed horizontally at equal intervals. The top and bottom of the locking link 18 both have several sets of through outlets 31. The right end of the locking link 18 is provided with a connecting rod square sleeve 12, and a connecting rod drive pin 13 is installed on the connecting rod square sleeve 12.

[0030] Analysis of the above content: The hollow rectangular locking link 18, through the square opening 30 and the through outlet 31, cooperates with the second connecting post 29 of the hook seat. The right end of the link square sleeve 12 is connected to the transmission device 15 via the link drive pin 13, realizing power transmission to drive multiple sets of hooks to move synchronously. When the transmission device 15 drives the link square sleeve 12, the locking link 18 moves laterally as a whole. Through the cooperation of the square opening 30, the through outlet 31 and the second connecting post 29, all hook seats 17 and adjustable hooks 16 are driven synchronously to lock or unlock. The hollow structure reduces weight while ensuring strength, avoiding the problem of easy deformation of traditional welded links. The multiple sets of square openings 30 and through outlets 31 are evenly distributed, which makes the synchronization of multiple sets of hooks good. Processing does not require welding, reducing labor costs, shortening the cycle, and improving the stability of transmission under high water head.

[0031] Example 3:

[0032] Please see Figure 1-6The present invention provides a technical solution based on Embodiment 1: the driving device 14 includes a hydraulic base 5, a hydraulic cylinder 7, and a fork-shaped connector 10. The top of the hydraulic cylinder 7 is provided with a locking bolt 9, and the top of the hydraulic cylinder 7 is mounted on the hydraulic base 5 through the locking bolt 9. The fork-shaped connector 10 is mounted on the bottom driving end of the hydraulic cylinder 7, and a fork-shaped connector pin 11 is provided on the fork-shaped connector 10.

[0033] Analysis of the above content: The hydraulic cylinder 7 is fixed to the hydraulic base 5 by the locking bolt 9. The fork-shaped connector 10 at the bottom drive end is connected to the transmission device 15 via the fork-shaped connector pin 11, converting hydraulic power into linear driving force. When the water head needs to open the door, the hydraulic cylinder 7 extends and pushes the transmission device 15 through the fork-shaped connector 10 and the fork-shaped connector pin 11. When the door needs to be closed and locked, the hydraulic cylinder 7 retracts and pulls the transmission device 15. The hydraulic cylinder 7 has stable power and large output force, which can overcome the water pressure under high water head and ensure drive reliability. The connection method of the fork-shaped connector 10 and the fork-shaped connector pin 11 makes the transmission force more uniform and adaptable to high load conditions.

[0034] Example 4:

[0035] Please see Figure 1-6 The present invention provides a technical solution based on Embodiment 1: the transmission device 15 includes a connecting rod seat 6 and an L-shaped connecting rod 8. The L-shaped connecting rod 8 is installed in the connecting rod seat 6 through a rotating shaft. The L-shaped connecting rod 8 has an L-shaped structure. The upper end of the L-shaped connecting rod 8 is connected to the fork-shaped connector 10 through a fork-shaped connector pin 11. The lower end of the L-shaped connecting rod 8 is connected to the connecting rod square sleeve 12 through a connecting rod drive pin 13.

[0036] Analysis of the above: The L-shaped connecting rod 8 is installed in the connecting rod seat 6 via a rotating shaft. The upper end is connected to the fork-shaped connector 10 via the fork-shaped connector pin 11, and the lower end is linked to the connecting rod square sleeve 12 via the connecting rod drive pin 13. This converts the linear motion of the hydraulic cylinder 7 into the rotational motion of the L-shaped connecting rod 8, which in turn drives the locking connecting rod 18 to move laterally. When the hydraulic cylinder 7 extends, it pushes the L-shaped connecting rod 8 to rotate around the rotating shaft of the connecting rod seat 6, and the lower end drives the locking connecting rod 18 to move to release the locking hook. When the hydraulic cylinder 7 retracts, it pulls the L-shaped connecting rod 8 to rotate, and the lower end drives the locking connecting rod 18 to move to lock the locking hook. The lever transmission structure of the L-shaped connecting rod 8 can efficiently transmit power, and the rotating shaft connection makes the transmission smoother. Under high water head, it can stably convert the driving power into the movement of the locking connecting rod, ensuring the reliability of the locking and unlocking actions.

[0037] Working principle: When the flush door needs to be closed and locked, the hydraulic cylinder 7 of the drive device 14 is fixed to the hydraulic seat 5 by the locking bolt 9. Its bottom drive end retracts, and pulls the L-shaped connecting rod 8 of the transmission device 15 through the fork joint 10 and the fork joint pin 11. The L-shaped connecting rod 8 rotates around the rotating shaft installed in the connecting rod seat 6. The lower end drives the connecting rod square sleeve 12 of the locking connecting rod 18 through the connecting rod drive pin 13, so that the hollow rectangular locking connecting rod 18 moves laterally as a whole. The latching link 18 engages with the second connecting post 29 of the latch seat 17 via the square opening 30 and the through outlet 31 on its surface, synchronously driving multiple sets of latch seats 17 to move: the lower clamping plate 25 and the upper clamping plate 26 of the latch seat rotate relative to the latch seat 24 around the rotating post 28, ultimately making the latch seat 24 precisely lock with the adjustable latch 16 at the bottom of the door panel assembly 2. The adjustable latch 16 passes through the bolt hole 23 of the welding block 19 via the adjusting bolt 22, allowing the position of the latch plate 20 and the fixed latch 21 to be pre-adjusted to ensure a suitable locking gap under high water head. At this time, the door panel assembly 2 and the door frame assembly 1 are tightly fitted together, achieving a seal. When it is necessary to open the flushing door, the driving end of the hydraulic cylinder 7 extends, pushing the L-shaped link 8 to rotate in the opposite direction, causing the latching link 18 to move in the opposite direction, so that the latch seat 24 and the fixed latch 21 are disengaged from the locked state. Under the action of water pressure or other auxiliary forces, the door panel assembly 2 rotates and opens around the door panel rotating hinge assembly 3. Throughout the process, the rotating column 28 of the locking hook seat 17 is designed to disperse the water pressure under high water head, and the non-welded hollow structure of the locking link 18 ensures stable transmission. The coordinated cooperation between the drive and transmission devices achieves efficient power transmission, jointly ensuring the reliable opening, closing and locking of the flushing door under high water head conditions.
