Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a gate water stopping device for water conservancy projects. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. Only by building water conservancy projects can we control water flows, prevent floods and waterlogging disasters, and regulate and distribute water to meet the needs of people's lives and production for water resources. At present, in the construction of water conservancy projects, the outlets of water supply and drainage, sewage treatment, pumping stations, channel drainage and other projects need to be water-stopped. There are many kinds of water-stopping devices currently in use, but there are still some shortcomings.

[0003] The existing patent (Announcement No.: CN202321746089.7) discloses a water stop device for water conservancy engineering construction. When the front of the water stop device is impacted, the bottom of the rear support seat is supported on the bottom of the water, which can support the back of the water stop device and resist the force on the front of the water stop device. It has a strong effect of preventing water flow impact and avoids the water stop device from tipping over easily due to force, resulting in water stop failure. In the process of implementing this solution, it was found that the following problems exist in the prior art and have not been well solved:

[0004] The water-stop device protects the rear of the valve through the support seat during use, but debris is easily accumulated in front of the valve when water flows. Once the water is drained, the debris will accumulate at the position of the support seat, so the staff needs to clean the debris frequently to prevent the debris from affecting the use of the valve. However, the cleaning work is difficult to operate and affects the staff's operation. Utility Model Content

[0005] In order to improve the problem that the above-mentioned debris may easily affect the use of the valve when the door is opened, and the debris around the valve needs to be cleaned frequently, the utility model provides a gate water-stopping device for water conservancy projects.

[0006] The utility model provides a gate water-stopping device for water conservancy projects, which adopts the following technical solutions:

[0007] A gate water stop device for a water conservancy project, comprising a valve body and a bottom plate, a lifting mechanism is arranged above the valve body, a linkage block is connected to the front side of the valve body, a guide block is connected to the bottom of the linkage block, a dust collecting box is arranged inside the linkage block, a movable block is arranged inside the dust collecting box, and a threaded nail is connected inside the movable block;

[0008] The outer side of the bottom plate is connected with an extension block, the top of the bottom plate is connected with a connecting rod, the top of the connecting rod is connected with a return spring, and the top of the return spring is connected with a storage block.

[0009] Through the above technical scheme, it is convenient to collect the debris driven by the guide block through the cooperation between the linkage block and the dust collecting box, thereby reducing the amount of debris accumulated under the valve and reducing the number of cleaning times. Secondly, the linkage block is automatically cleaned by the automatic opening and closing of the bottom plate, without the need for manual cleaning by the staff, thus reducing the workload of the staff.

[0010] Optionally, in the above-mentioned gate water-stopping device for a water conservancy project, the lifting mechanism is composed of a cylinder and a piston rod, and the piston rod and the valve body are installed in an integrated manner, and limiting mechanisms are arranged on both sides of the valve body.

[0011] Through the above technical solution, the lifting mechanism can provide driving force for the valve body, facilitating its normal lifting.

[0012] Optionally, in the above-mentioned gate water-stop device for water conservancy projects, the linkage block is connected to the valve body by hot-melt connection, the linkage block is connected to the guide block by hot-melt connection, and the guide block has a trapezoidal structure.

[0013] Through the above technical solution, it is convenient to guide the debris upward through the guide block, thereby ensuring the cleaning effect of the debris.

[0014] Optionally, in the above-mentioned gate water-stopping device for a water conservancy project, the dust box is connected to the linkage block by a sliding connection, the dust box is connected to the movable block by a sliding connection, and threaded nails are symmetrically distributed on both sides of the movable block.

[0015] Through the above technical solution, it is convenient to collect debris through the dust collecting box, and the probability of debris being washed out by water flow is reduced through the movable block.

[0016] Optionally, in the above-mentioned gate water-stopping device for a water conservancy project, the connection between the base plate and the linkage block is a sliding connection, the base plate and the extension block form an "L"-shaped structure, and connecting rods are symmetrically distributed on both sides of the base plate.

[0017] Through the above technical solution, it is convenient to cooperate with the linkage block through the bottom plate. When the linkage block descends, the bottom plate is flushed open by the water flow, so that the water flow flushes the inside of the linkage block.

[0018] Optionally, in the above-mentioned gate water-stopping device for a water conservancy project, the connecting rod forms a spring reset structure with the storage block through a reset spring, the storage blocks are symmetrically distributed on both sides of the interior of the linkage block, and the connection between the connecting rod and the storage block is a sliding connection.

[0019] Through the above technical solution, the bottom plate is usually kept in a closed state by the reset spring, thereby preventing debris from entering the interior of the linkage block.

[0020] In summary, the present invention has at least one of the following beneficial effects:

[0021] By arranging a guide block and a linkage block on the front side of the valve body, debris enters the linkage block along the guide block under the impact of the water flow, and then enters the dust box. Secondly, a movable block is arranged inside the dust box to prevent the debris from entering the dust box and then floating out from the dust box.

[0022] By setting a bottom plate at the bottom of the linkage block, when the valve body is lowered, the water flow impacts the bottom plate to cause the bottom plate to rise, so that the water flow enters the interior of the linkage block to flush the interior of the linkage block. When the valve body completes the water-stopping work, the reset spring drives the bottom plate to reset without affecting it. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following is combined with Figure 1-5 The utility model is described in further detail.

[0030] Please refer to the attached figure in the instruction manual Figure 1-5, the utility model provides an embodiment: a gate water stop device for water conservancy projects, including a valve body 1 and a bottom plate 8, a lifting mechanism 2 is arranged above the valve body 1, and the lifting mechanism 2 provides a driving force for the valve body 1 to ensure the subsequent work, the front side of the valve body 1 is connected with a linkage block 3, and the bottom of the linkage block 3 is connected with a guide block 4, through which the debris is circulated to improve the cleaning effect, a dust box 5 is arranged inside the linkage block 3, and a movable block 6 is arranged inside the dust box 5, and the movable block 6 prevents the debris from sliding out of the dust box 5 to ensure its use, and a threaded nail 7 is connected inside the movable block 6;

[0031] An extension block 9 is connected to the outer side of the bottom plate 8, and a connecting rod 10 is connected to the top of the bottom plate 8. The bottom plate 8 is connected via the connecting rod 10 to facilitate subsequent lifting work. A return spring 11 is connected to the top of the connecting rod 10, and a storage block 12 is connected to the top of the return spring 11. The storage block 12 limits the connecting rod 10 to ensure its stable lifting.

[0032] See the attached drawings in the specification Figure 1-5 The lifting mechanism 2 is composed of a cylinder and a piston rod, and the piston rod is integrated with the valve body 1. Limiting mechanisms are arranged on both sides of the valve body 1. The lifting mechanism 2 provides driving force for the valve body 1 to facilitate its normal lifting.

[0033] See the attached drawings in the specification Figure 1-5 The linkage block 3 is connected to the valve body 1 by hot-melt connection, and the linkage block 3 is connected to the guide block 4 by hot-melt connection. The guide block 4 is a trapezoidal structure, and the debris is guided upward by the guide block 4 to ensure the cleaning effect of the debris.

[0034] See the attached drawings in the specification Figure 1-5 The dust box 5 is connected to the linkage block 3 in a sliding manner, and the dust box 5 is connected to the movable block 6 in a sliding manner. Threaded nails 7 are symmetrically distributed on both sides of the movable block 6. The dust box 5 collects debris, and the movable block 6 reduces the probability of debris being washed out by water.

[0035] See the attached drawings in the specification Figure 1-5 The connection between the bottom plate 8 and the linkage block 3 is a sliding connection. The bottom plate 8 and the extension block 9 form an "L"-shaped structure. Connecting rods 10 are symmetrically distributed on both sides of the bottom plate 8. Through the cooperation between the bottom plate 8 and the linkage block 3, the bottom plate 8 is flushed open by the water flow when the linkage block 3 descends, so that the water flow flushes the inside of the linkage block 3.

[0036] See the attached drawings in the specification Figure 1-5The connecting rod 10 forms a spring return structure with the storage block 12 through the return spring 11. The storage blocks 12 are symmetrically distributed on both sides of the linkage block 3. The connection between the connecting rod 10 and the storage block 12 is a sliding connection. The return spring 11 makes the bottom plate 8 usually in a closed state to prevent debris from entering the linkage block 3.

[0037] Working principle: When the gate water stop device for water conservancy projects is used, first, water flows toward the valve body 1 at ordinary times, so that debris flows along the water flow and impacts the valve body 1. Then, when the debris impacts the guide block 4, it flows upward along the guide block 4, reaches the top of the linkage block 3, and then settles inside the dust box 5 below. When the valve body 1 rises, the threaded nail 7 is used to release the limit fixation of the movable block 6, and at the same time, the limit fixation of the dust box 5 is released, and the dust box 5 is taken out to clean the debris inside and reset it;

[0038] As mentioned above, when the valve body 1 is closed and reset, the water flow impacts the extension block 9, causing the extension block 9 to drive the bottom plate 8 to rise until the extension block 9 fits against the top linkage block 3. At this time, the water flow flushes the linkage block 3 through the groove under the bottom plate 8 to clean the inside of the linkage block. When the valve body 1 stops moving, the impact force of the water flow becomes smaller, and the reset spring 11 drives the connecting rod 10 to reset, so that the bottom plate 8 is reset to prevent debris from entering the inside of the linkage block 3 through the groove.

[0039] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
