Description

Technical Field

[0001] The utility model is applicable to the technical field of water conservancy construction, and particularly relates to a river interception device. Background Art

[0002] At present, water conservancy projects refer to projects built to eliminate water disasters and develop and utilize water resources. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, ferries, rafts, fishways, etc. to achieve their goals. During the construction of water conservancy projects, corresponding intercepting devices are needed to intercept the water passing through the canal, so as to facilitate the staff to carry out corresponding construction.

[0003] However, when intercepting the water inside the water conservancy river channel, the corresponding interceptor plate is inserted vertically into the river channel to block the inside of the river channel. However, for rivers of different widths, the interceptor plate with a single structure and function cannot adjust the interception area according to the different inner diameters of the river channel. As a result, once the size of the interceptor plate and the inner diameter of the river channel are different, the interception quality inside the river channel is easily affected. Therefore, we propose a river interception device. Utility Model Content

[0004] The main purpose of the utility model is to provide a river interception device, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A river interception device comprises a water baffle, wherein sliding baffles are slidably inserted on both sides of the water baffle, a transmission frame is vertically fixedly installed on the middle end surface of the side of the water baffle, storage grooves are opened on both sides of the water baffle, and the sliding baffles are slidably inserted in the storage grooves;

[0007] A bidirectional screw is installed at the middle end of the transmission frame for vertical rotation through a bearing, and movable sleeves are movably sleeved on both ends of the outer side of the bidirectional screw. Transmission blocks are fixedly installed on both ends of the outer side of each movable sleeve, and the transmission blocks penetrate and slide inside the side of the transmission frame;

[0008] A sliding plate is fixedly installed on the end surface of each transmission block away from the movable sleeve, and the sliding plate is slidably installed on the outside of the transmission frame. A push rod is hinged on the outer surface of each sliding plate through a rotating shaft, and the end of the push rod away from the transmission sleeve is hinged on the outside of the sliding plate through a rotating shaft.

[0009] By adopting the above technical solution, the vertical movement force of the transmission sleeve is converted into a horizontal driving force on the sliding baffle through the rotational transmission action of the bidirectional screw on the transmission sleeve and the transmission conversion action of the push rod, so that the sliding baffle can move on both sides inside the water baffle, thereby adjusting the overall water retaining area between the water baffle and the sliding baffle, so that the water baffle and the sliding baffle can be suitable for the inner walls of rivers of different widths, thereby providing the interception applicability of the entire interception equipment.

[0010] As an optional solution of the technical solution of the present application, a mounting plate is fixedly installed on the side surface of each sliding baffle away from the transmission frame, and a reinforcing pointed cone rod is fixedly installed on the outer surface of each mounting plate, and the number of the reinforcing pointed cone rods is several groups.

[0011] By adopting the above technical solution, the interception reinforcement stability of the sliding baffle is improved by reinforcing the structure of the pointed cone rod.

[0012] As an optional solution of the technical solution of the present application, a servo motor is fixedly installed on the top of the inner side of the transmission frame, and the bottom of the servo motor transmission shaft is fixedly connected to the top surface of the bidirectional screw rod through a coupling.

[0013] By adopting the above technical solution, the required power source for the rotation of the bidirectional screw rod is provided through the structural function of the servo motor.

[0014] As an optional solution of the technical solution of the present application, limiting grooves are provided inside both ends of the side of the transmission frame, and the transmission block is slidably installed inside the limiting groove.

[0015] By adopting the above technical solution, the rationality of the transmission adjustment of the entire device is ensured by the guiding and limiting effect of the limiting groove on the transmission block.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. A river interception device according to the technical solution of the present application is slidingly inserted into the inside of both sides of a water baffle through a sliding baffle, and then a transmission sleeve is sleeved on the two ends of the outer side of a bidirectional screw rod, and the two sets of transmission sleeves can move horizontally toward each other or relative to each other inside the transmission frame under the rotational transmission action of the bidirectional screw rod, and then the vertical movement force of the transmission sleeve is converted into a horizontal driving force on the sliding baffle under the transmission conversion action of the push rod, so that the sliding baffle can move on both sides inside the water baffle, and then the overall water retaining area between the water baffle and the sliding baffle is adjusted, so that the water baffle and the sliding baffle can be suitable for the inner walls of rivers of different widths, thereby providing interception applicability of the entire interception device.

[0018] 2. A river interception device according to the technical solution of the present application is provided with a mounting plate and a reinforced pointed cone rod on the outer side of a sliding baffle. After the reinforced pointed cone rod is inserted into the soil on the inner wall of the river channel, it can provide corresponding gripping support force to the water retaining plate and the sliding baffle, thereby preventing the water retaining plate and the sliding baffle from shaking arbitrarily after being impacted, and further improving the interception stability inside the river channel.

DETAILED DESCRIPTION

Storage grooves 4 are opened on both sides of the water baffle 1, and the sliding baffles 11 are slidably inserted in the storage grooves 4.

[0027] During operation, after the water baffle plate 1 and the sliding baffle plate 11 are synchronously vertically plugged into the river channel to be intercepted, the servo motor 26 is turned on through an external control switch, so that its operation drives the bidirectional screw rod 21 to rotate synchronously, and then the two groups of transmission sleeves can synchronously move vertically toward each other inside the transmission frame 2 under the guiding and limiting action of the limit groove 41 on the transmission block 23.
