Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drainage gates, in particular to an anti-silting gate groove. Background Art
[0002] like Figure 1 and Figure 2 As shown, in the prior art, urban rainwater is generally discharged into the river through the drainage culvert 1 through the urban embankment. The drainage culvert 1 is usually provided with a gate mechanism at the place leading to the river. The inner side is generally connected to a drainage pump station or other drainage facilities. When necessary, the gate 3 can be closed to prevent the river water from entering the inner side of the drainage culvert 1, so as to facilitate the maintenance of drainage facilities such as the pump station inside the drainage culvert 1. The gate mechanism generally includes a gate 3, a hoist 6, and a connecting rod 5. In order to achieve a good water-stopping effect when the gate 3 is closed, the gate 3 is installed in the gate groove 4. The gate groove 4 is arranged along both sides and the bottom of the gate well 2. The depth of the gate groove 4 is generally about 20 cm. When the gate 2 is closed, the gate 2 needs to be embedded in the bottom gate groove 4 to effectively stop water. During daily operation, the gate 2 is lifted upward to ensure smooth drainage of the drainage culvert 1.
[0003] Since urban rainwater often contains a lot of impurities such as silt, it often flows into the bottom gate groove 4 with rainwater, causing siltation in the bottom gate groove 4. When the gate 3 needs to be closed, the gate 3 cannot be embedded in the bottom gate groove 4, resulting in a gap between the gate groove 4 and the gate 3, and the gate 3 cannot be effectively closed to stop water. Therefore, the bottom gate groove 4 needs to be frequently desilted. Due to the narrow space at the installation position of the gate 2, the bottom gate groove 4 is generally submerged, and desilting is difficult, which brings many inconveniences to the operation of the drainage culvert 1.
[0004] Therefore, how to reduce the amount of sediment in the water entering the gate slot to avoid siltation in the gate slot and ensure the normal drainage of the drainage culvert has become a technical problem that technical personnel in this field urgently need to solve. Utility Model Content
[0005] In view of the above-mentioned defects of the prior art, the utility model provides an anti-siltation gate groove, the purpose of which is to reduce the sediment deposition in the gate groove, ensure the effective water stopping of the gate and the normal drainage of the drainage culvert.
[0006] In order to achieve the above technical purpose, the utility model provides an anti-siltation gate slot, including a gate well, a gate, a gate slot, a connecting rod and a gate hoist, wherein the gate is arranged in the gate well, and the top is connected to the gate hoist through a connecting rod, the gate well is connected to a drainage culvert, the drainage culvert is provided with the gate slot corresponding to the inner bottom of the gate, and sand retaining bottom sills are respectively arranged on both sides of the gate;
[0007] The hoist can drive the gate to move up and down through the connecting rod. After the bottom of the gate is embedded in the gate groove and contacts the bottom of the gate groove, the bottom of the sand retaining sill can contact the inner bottom of the drainage culvert.
[0008] Preferably, the sand retaining sill consists of an upper hemispherical body and a lower column.
[0009] Preferably, the gate and the sand retaining sill are an integrated structure.
[0010] Beneficial effects of the utility model:
[0011] Due to the structural design, the utility model reduces the amount of silt in rainwater entering the bottom gate groove by setting a sand retaining bottom sill, avoids the silt in rainwater from being deposited in the drainage culvert, and ensures that the gate effectively stops water and the drainage culvert drains normally; further, since the bottom gate groove is set in the drainage culvert, the space is large and it is easy to clean even if silt is accumulated.

[0018] The concept, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings to fully understand the purpose, characteristics and effects of the present invention.
[0019] Example:
[0020] like Figure 3-Figure 5As shown, the anti-siltation gate slot includes a gate well 2, a gate 3, a gate slot 4, a connecting rod 5 and a hoist 6. The gate 3 is arranged in the gate well 2, and the top is connected to the hoist 6 through the connecting rod 5. The gate well 2 is connected to the drainage culvert 1. The gate slot 4 is arranged at the inner bottom of the drainage culvert 1 corresponding to the gate 3, and sand retaining bottom sills 7 are arranged on both sides of the gate 3.
[0021] The hoist 6 can drive the gate 3 to move up and down through the connecting rod 5. After the bottom of the gate 3 is lowered and embedded in the gate groove 4 and contacts the bottom of the gate groove 4, the bottom of the sand retaining bottom sill 7 can contact the inner bottom of the drainage culvert 1.
[0022] The main innovation of the utility model is that the sand retaining bottom sill 7 is provided to reduce the sand in the rainwater from entering the gate groove 4 at the bottom, thereby preventing the sand in the rainwater from being deposited in the drainage culvert 1.
[0023] The secondary innovation is that the gate slot 4 is opened in the drainage culvert 1. Since the drainage culvert 1 usually has a large space, it is easy to clear the silt even if it is silted.
[0024] Furthermore, since the drainage culvert 1 has a large space, it is convenient for silting. At the same time, since there is no siltation in the bottom gate groove 4, the gate 3 can be closed to stop water at any time as needed, reducing the difficulty of silting and facilitating the normal operation of the drainage culvert 1.
[0025] More specifically, Figure 5 As shown, the sand retaining bottom sill 7 is composed of an upper hemisphere and a lower column, with a lateral width of about 20 cm, a radius of the upper hemisphere of 10 cm, and an overall height of the sand retaining bottom sill 7 that can be determined according to the size of the drainage culvert 1, generally not less than 20 cm, to ensure that the sand retaining bottom sill 7 does not affect the normal drainage of the drainage culvert 1.
[0026] The sand retaining bottom sill 7 is parallel to the gate groove 4, and the gate 3 and the sand retaining bottom sill 7 are an integrated structure.
[0027] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
