Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy project drainage equipment, in particular to a water conservancy project drainage gate. Background Art

[0002] Water conservancy projects are important livelihood projects. When irrigating farmland, it is necessary to build drainage gate equipment on the river channel to control the up and down movement of the drainage gate to achieve control of the river water flow.

[0003] During the actual application process, researchers found that due to the long-term contact between the gate and water, moss and other dirt would adhere to its surface, affecting the normal operation of the gate. When cleaning the surface of the gate, existing personnel often rely on manual cleaning and scraping tools to operate, which not only has low cleaning efficiency but also has certain risks. Utility Model Content

[0004] The purpose of the utility model is to provide a drainage gate of a water conservancy project, which is used to solve the problem that existing personnel often rely on manual use of cleaning scraping tools to clean the gate surface, which not only has low cleaning efficiency but also has certain risks.

[0005] To achieve the above-mentioned purpose, the present invention provides a water conservancy project drainage gate, comprising:

[0006] The support frame is mounted on the gate base, and a gate is slidably connected to the inner side of the support frame. The gate is driven to rise and fall by the lifting structure installed on the top of the support frame. A set of card boxes are fixedly installed on the front and rear side surfaces of the support frame respectively;

[0007] The liquid spray assembly is used to clean the front and rear sides of the gate, and includes two groups of liquid spray pipes, which are provided with multiple groups of high-pressure nozzles on the side facing the gate surface. The two groups of liquid spray pipes are connected to the liquid suction pump installed on the support frame through a hose. The two groups of liquid spray pipes are slidably installed on the corresponding card boxes. Multiple groups of counterweights are installed at the bottom of the liquid spray pipe, and a hook body is installed at the upper end. The hook body is connected to the winding roller at the top of the support frame through a steel wire rope, and the winding roller rotates to pull the liquid spray pipe up and down in the vertical direction.

[0008] As a further solution of the present invention, the lifting structure includes a transmission motor and a transmission screw. The transmission motor is fixedly installed on the top of the support frame, with its output shaft facing vertically and coaxially fixedly connected to the transmission screw through a coupling. An installation cavity for inserting the transmission screw is vertically opened at the top of the gate, and a fixing nut threadedly connected to the transmission screw is fixed at the port of the installation cavity.

[0009] As a further solution of the present invention, two groups of bonding plates are fixed at both ends of the spray pipe, and a card block is fixedly installed on the bonding plate away from one end connected to the spray pipe. A sliding groove adapted for the sliding of the card block is provided on one side of the card box, and the surface of one side of the bonding plate is bonded and slidably connected to the card box.

[0010] As a further solution of the present invention, the number of the winding rollers is two, and the two winding rollers are correspondingly powered by two winding motors fixedly connected to the top of the support frame.

[0011] As a further solution of the present invention, the front and rear side surfaces of the support frame are fixedly connected with a fixing box for accommodating the winding roller.

[0012] As a further solution of the present invention, the liquid outlet end of the liquid pump is fixedly connected to a tee through a hose, the liquid outlet end of the tee is fixedly connected to the two liquid spray pipes through hoses, and the liquid inlet end of the tee is fixedly connected to the liquid outlet end of the liquid pump through a hose.

[0013] As a further solution of the present invention, the liquid outlet end of the liquid pump is fixedly connected to a weighted filter body through a hose, and a filter hole is opened through the outer surface of the weighted filter body.

[0014] Compared with the prior art, the utility model sets a liquid spraying assembly on the supporting frame. When the gate needs to be flushed, the startup of the liquid pump and the winding motor is controlled. At this time, the liquid pump draws water from the river channel into the three-way pipe through the counterweight filter body, enters the liquid spraying pipe, and is sprayed out through the high-pressure nozzle to flush the gate. Since the high-pressure nozzle is close to the gate, the gate can still be effectively flushed even in water. Furthermore, the forward and reverse rotation of the winding motor can drive the rotation of the winding roller, thereby winding and releasing the wire rope, causing the liquid spraying pipe and the counterweight block combination to move up and down, and a large area of the gate surface is flushed, with a better cleaning effect.

[0020] The technical solution of the present utility model will be further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1 As shown, in an embodiment of the present utility model, a drainage gate of a water conservancy project comprises a support frame 1, which is installed on a gate base, and a gate 2 is slidably connected to its inner side. The gate 2 is driven up and down by a lifting structure installed on the top of the support frame 1, and a group of card boxes 5 are fixedly installed on the front and rear side surfaces of the support frame 1; a liquid spraying assembly is used to clean the front and rear sides of the gate 2, comprising two groups of liquid spraying pipes 6, which are provided with multiple groups of high-pressure nozzles on the side facing the surface of the gate 2, and the two groups of liquid spraying pipes 6 are connected to the liquid pump 14 installed on the support frame 1 through hoses. The two groups of liquid spraying pipes 6 are slidably installed on the corresponding card boxes 5, and multiple groups of counterweights 8 are installed at the bottom of the liquid spraying pipe 6, and a hook body 9 is installed on the upper end thereof. The hook body 9 is connected to the winding roller 13 on the top of the support frame 1 through a steel wire rope 10, and the winding roller 13 rotates and drives the liquid spraying pipe 6 to be lifted and lowered in the vertical direction;

[0022] The utility model raises or lowers the gate 2 through the lifting structure, thereby controlling the flow and closing of the water flow. When the gate 2 has been used for a long time and needs to be cleaned and maintained, the winding roller 13 rotates and drives the spray pipe 6 to rise and fall in the vertical direction, and at the same time, the liquid pump 14 is started to supply liquid to the two groups of spray pipes 6. The high-pressure nozzle sprays the cleaning liquid at high pressure on the surface of the gate 2, and the impact of the liquid cleans the stains attached to the gate 2.

[0023] In addition, the utility model uses a card box 5 fixedly installed on the surface of the support frame 1 to limit and guide the lifting and lowering movement of the spray pipe 6. At the same time, the gravity of multiple groups of counterweights 8 assists the spray pipe 6 to move downward, ensuring the stability of the vertical sliding of the spray pipe 6 during the spraying operation.

[0024] like Figure 1As shown, in the embodiment of the present utility model, the lifting structure includes a transmission motor 4 and a transmission screw 3. The transmission motor 4 is fixedly mounted on the top of the support frame 1, with its output shaft facing vertically and coaxially fixedly connected to the transmission screw 3 through a coupling. A mounting cavity for inserting the transmission screw 3 is vertically opened on the top of the gate 2, and a fixed nut threadedly connected to the transmission screw 3 is fixed at the port of the mounting cavity. The utility model drives the transmission screw 3 to rotate synchronously by starting the transmission motor 4, and cooperates with the spiral transmission of the fixed nut to drive the gate 2 to rise and fall linearly.

[0025] Of course, in actual design, the preferred transmission motor 4 and transmission screw 3 can also be replaced by other components with lifting and lowering driving capabilities, such as a hydraulic cylinder.

[0026] like Figures 1 to 3 As shown, in the embodiment of the present utility model, two groups of fitting plates 7 are fixed at both ends of the spray pipe 6, and a card block 16 is fixedly installed on the fitting plate 7 away from one end connected to the spray pipe 6. A slide groove adapted to the sliding of the card block 16 is provided on one side of the card box 5. The surface of one side of the fitting plate 7 is fitted and slidably connected to the card box 5, and the card block 16 slides along the slide groove to improve the stability of the lifting and sliding of the spray pipe 6.

[0027] like Figure 1 and Figure 4 As shown, in the embodiment of the present utility model, the number of the winding rollers 13 is two, and the two winding rollers 13 are correspondingly powered by the two winding motors 12 fixedly connected to the top of the support frame 1. It should be noted that personnel in this field connect all electrical components in this case, such as the transmission motor 4, the winding motor 12 and the liquid pump 14, etc., to their corresponding power supplies through wires, and should select a suitable controller, such as a PLC controller or a single-chip microcomputer, according to actual conditions to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between the electrical components is completed in the working order. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and no longer explains the electrical control.

[0028] like Figure 1 and Figure 4 As shown, in the embodiment of the present invention, the front and rear side surfaces of the support frame 1 are fixedly connected with a fixing box 11 for accommodating the winding roller 13. The fixing box 11 protects the winding roller 13 to prevent it from being directly exposed to the environment.

[0029] like Figure 1As shown, in the embodiment of the present utility model, the liquid outlet end of the liquid pump 14 is fixedly connected to the tee pipe 15 through a hose, the liquid outlet ends of the tee pipe 15 are respectively fixedly connected to the two liquid spray pipes 6 through hoses, and the liquid inlet end of the tee pipe 15 is fixedly connected to the liquid outlet end of the liquid pump 14 through a hose;

[0030] At the same time, the liquid outlet end of the liquid pump 14 is fixedly connected to a counterweight filter body 17 through a hose. The outer surface of the counterweight filter body 17 is penetrated with a filter hole. The liquid pump 14 draws water from the river channel into the three-way pipe 15 through the counterweight filter body 17 to supply air for liquid spraying.

[0031] To sum up the above, the utility model sets a liquid spray component on the support frame 1. When the gate 2 needs to be flushed, the start-up of the liquid pump 14 and the winding motor 12 is controlled. At this time, the liquid pump 14 draws water from the river channel into the three-way pipe 15 through the counterweight filter body 17, enters the liquid spray pipe 6, and is sprayed out through the high-pressure nozzle to flush the gate 2. Since the high-pressure nozzle is close to the gate 2, the gate 2 can still be effectively flushed even in water. Furthermore, the forward and reverse rotation of the winding motor 12 can drive the rotation of the winding roller 13, thereby winding and releasing the wire rope 10, so that the combination of the liquid spray pipe 6 and the counterweight block 8 moves up and down, and a large area of the surface of the gate 2 is flushed, and the cleaning effect is better.

[0032] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.
