Technical Field

[0001] The utility model relates to the technical field of gate valves, in particular to a double-row chain-type integrated slot gate. Background Art

[0002] The gate is a control facility used to close and open the discharge channel. It is an important component of hydraulic structures and can be used to intercept water flow, control water level, regulate flow, discharge sediment and floating objects, etc. The Chinese patent application with publication number CN216555208U discloses a double-axis power transmission device for a slot gate. The slot gate is opened or closed by setting a transmission chain on the edge of the slot gate plate, setting drive gears at both ends of the transmission shaft and engaging the transmission chain. However, the transmission chain is directly exposed to the outside. Especially in the use of open channels, there are often foreign objects such as soil, branches and leaves in the water channel. Foreign objects are stuck in the transmission chain, causing working failures and even reducing the service life of the transmission chain. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a double-row chain integrated slot gate in view of the above-mentioned technical deficiencies. An anti-fouling belt is arranged on the outer side of the chain to solve the problem of working failure caused by foreign matter stuck in the transmission chain.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a double-row chain integrated slot gate, including a door-shaped bracket, a driving frame is provided on the top of the bracket, a gate plate is hinged in the bracket, arc-shaped side panels are provided on both sides of the gate plate, arc-shaped grooves are provided in the arc-shaped edges of the arc-shaped side panels, chains are provided in the arc-shaped grooves, and anti-fouling belts are provided on the outside of the chain, and the chain is transmission-connected to the driving frame.

[0005] To further optimize the technical solution, sprocket groups are respectively provided at both ends of the driving frame, the chain is engaged in the sprocket groups, the two ends of the anti-fouling belt are respectively fixed at the two ends of the arc groove, and the anti-fouling belt is wrapped around the outside of the sprocket group.

[0006] To further optimize the technical solution, the sprocket group includes a driving wheel and two guide wheels, the two guide wheels are respectively arranged on both sides of the lower part of the driving wheel, the chain passing through the driving frame is wound around the inner sides of the two guide wheels, and the chain between the two guide wheels is wound around the outer sides of the driving wheel;

[0007] A guide cover is arranged on the outside of the driving wheel, and a guide shaft is arranged on the upper side of each guide wheel. The anti-fouling belt passing through the driving frame is wound around the inner sides of the two guide shafts, and the anti-fouling belt between the two guide shafts is wound around the outside of the guide cover.

[0008] To further optimize the technical solution, a transverse axis is arranged at the lower side of the driving frame, a driving wheel in the sprocket assembly is coaxially fixedly connected to the end of the transverse axis, and a driving motor is transmission-connected to the middle of the transverse axis.

[0009] Compared with the prior art, the utility model has the following advantages: 1. By providing an anti-fouling belt on the outside of the chain, foreign matter can be prevented from getting stuck in the transmission chain to a certain extent, thereby achieving the effect of blocking foreign matter; 2. Since the chain is arranged between the anti-fouling belt and the arc groove, the anti-fouling belt avoids mutual interference between the chain and the anti-fouling belt in the sprocket group under the guidance of the guide shaft and the guide cover. The anti-fouling belt can resist the invasion of external foreign matter, thereby improving the operating reliability of the gate valve and extending its service life.
