Description

Technical Field

[0001] The present invention belongs to the technical field of flow control valves, and specifically relates to an adjustable flow control valve for shotcrete in tunneling. Background Art

[0002] A flow control valve is a device used to control the flow rate of fluids and has a wide range of applications in various industrial and civil fields. In industries such as chemical engineering, petroleum, metallurgy, and power, flow control valves are widely used in various fluid transportation systems, such as controlling the flow rate of liquids and gases in pipelines to ensure the stability and safety of the production process. For example, in petrochemical production, precisely controlling the flow rate of various raw materials and products is crucial for ensuring the smooth progress of chemical reactions and product quality.

[0003] An adjustable flow control valve for shotcrete in tunneling is a device specifically used to control the flow rate of concrete during the shotcrete process and usually adopts the throttling principle to control the flow rate. By changing the size of the throttle orifice inside the valve, the flow area of the concrete is adjusted, thereby achieving the control of the flow rate. When it is necessary to increase the flow rate, the throttle orifice is opened through the operating mechanism, enabling the concrete to pass through the valve more smoothly; conversely, when it is necessary to decrease the flow rate, the throttle orifice is closed.

[0004] Currently, in the existing technology, there may be a certain amount of concrete inside the flow control valve at the end of the operation. This concrete forms hard blocks inside the valve, causing additional resistance and wear during the opening and closing process of the valve, accelerating the wear and aging of components, reducing the effective number of uses and the overall service life of the valve. Moreover, the concrete contains components such as cement and sand and has a certain alkalinity. These components will corrode the internal structure of the valve body when inside the valve body, further affecting the performance and service life of the valve and being unfavorable for the operation of the valve.

[0005] Therefore, the present invention provides an adjustable flow control valve for shotcrete in tunneling. Summary of the Invention

[0006] In order to make up for the deficiencies of the existing technology and solve at least one of the technical problems proposed in the background art.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: An adjustable flow control valve for shotcrete includes a valve body. Pipes are symmetrically arranged on the outer wall of the valve body, and the pipes and the valve body are connected by flange plates. An adjustment assembly is arranged inside the valve body, and the adjustment assembly is used to adjust and control the flow rate of concrete. A water tank is fixedly installed at the bottom of the valve body, and a liquid is arranged inside the water tank. An inlet and an outlet are respectively arranged on both sides of the water tank. A cleaning assembly is arranged inside the water tank, and the cleaning assembly includes a scraping block. The cleaning assembly is used to drive the scraping block to clean the inside of the valve body. Lifting assemblies are symmetrically arranged inside the water tank, and the lifting assemblies are used to drive the cleaning assembly to enter the valve body from the water tank. The two lifting assemblies are respectively arranged on one side of the cleaning assembly;

[0008] During use, the concrete pipeline is connected to the valve body by using a flange plate. The liquid is introduced into the water tank through the inlet on one side of the water tank. When it is necessary to introduce concrete into the mold, the adjustment assembly is controlled to open, and the concrete can flow from the pipeline through the valve body to the mold. When it is necessary to control the flow rate of concrete, by controlling the movement of the adjustment assembly in the valve body, the flow control operation of the concrete can be realized. When the shotcrete operation in the mold is completed, the adjustment assembly blocks and closes the concrete in the two pipelines in the valve body. Subsequently, by controlling the lifting assembly to drive the cleaning assembly to enter the valve body from the water tank, the cleaning assembly can drive the scraping block to clean the inside of the valve body, thereby cleaning out the concrete placed in the valve body, ensuring the cleanliness of the valve body, and preventing the remaining concrete in the valve body from forming hard blocks through time settlement when the concrete spraying operation is completed, which causes additional resistance and wear to the valve during the opening and closing process, accelerates the wear and aging of components, and affects the use effect and overall service life of the valve during the next use, playing a role in automatically cleaning the valve when the valve operation is completed, and ensuring and improving the service life and effect of the valve.

[0009] Preferably, the adjustment assembly includes an adjustment motor fixedly installed on the top of the valve body. The output end of the adjustment motor is fixedly installed with a valve block, and the outer wall of the valve block is slidably connected to the inner wall of the valve body. When it is necessary to control the flow rate of concrete, the adjustment motor is driven to drive the valve block to move. When it is necessary to increase the flow rate, the adjustment motor is driven to drive the valve block to move upward in the valve body. When it is necessary to decrease the flow rate, it is the opposite, playing a role in controlling and adjusting the flow rate of concrete.

[0010] Preferably, slide rails are symmetrically and fixedly installed on the inner wall of the water tank. The inner walls of the two slide rails are both slidably connected with electric sliders. Baffles are fixedly installed on the outer walls of the two electric sliders. Both baffles are slidably connected with the bottom of the valve body. When the concrete spraying operation ends, control the adjustment motor to drive the valve block to move to the bottom of the valve body. When the valve block moves downward, the valve block can push the concrete on the inner wall of the valve body downward, thereby cleaning the inner wall of the valve body. When the valve block moves to the bottom end of the valve body, at this time, the valve block completely blocks the two pipelines, thus achieving the effect of closing the valve. When the valve block blocks and closes the pipeline, at this time, the electric slider drives the baffle to move in the slide rail, and the baffle will move and open from the bottom of the valve body. The concrete scraped off by the valve block will fall into the water tank from between the two baffles, playing the role of opening and closing to drop the concrete, and also providing a path for the subsequent cleaning component to drive the scraping block to clean the bottom of the valve block. It should be noted here that the initial positions of the two baffles are directly below the valve block. When the concrete flows in the valve body, the two baffles support the flow of the concrete.

[0011] Preferably, the cleaning component further includes a support plate. The two sides of the support plate are slidably connected with the inner wall of the water tank. A hollow motor is fixedly installed on the top of the support plate. The output end of the hollow motor is fixedly installed with a ring shaft. Rotating rods are symmetrically and fixedly installed on the outer wall of the ring shaft. The tops of the two rotating rods are both fixedly connected with the bottom of the scraping block. The two sides of the top of the scraping block are both inclined planes. The top of the scraping block can be rotatably connected with the bottom of the valve block. When the two baffles are opened, at this time, the lifting component drives the cleaning component to move upward from the water tank, so that the scraping block contacts the bottom of the valve block. When the two baffles are completely opened, the scraping block contacts the bottom of the valve block. Subsequently, control the hollow motor to drive the ring shaft to rotate. When the ring shaft rotates, the ring shaft drives the scraping block to rotate on the bottom of the valve block through the two rotating rods, thereby rotating and scraping the concrete attached to the bottom of the valve block, playing the role of scraping the concrete.

[0012] Preferably, a retaining rod is fixedly installed on the top of the support plate. A cylinder body is fixedly installed on the top of the retaining rod. The outer wall of the retaining rod is rotatably connected with the inner wall of the ring shaft. The top of the cylinder body is rotatably connected with the inner wall of the scraping block. A water-pushing component is arranged inside the cylinder body. Spray openings are symmetrically formed in the inner wall of the scraping block. When the scraping block scrapes the bottom of the valve block, the water-pushing component inside the cylinder body operates, and the water flow placed inside the cylinder body will be driven by the water-pushing component to spray out from the spray openings formed in the inner wall of the scraping block. Thus, when the scraping block scrapes the bottom of the valve block, the water flow sprays water on the bottom of the valve block, accelerating the cleaning speed and improving the cleaning effect at the same time.

[0013] Preferably, a limiting plate is fixedly installed on the inner wall of the scraping block, and a plurality of water flow pipes are fixedly installed on the top of the limiting plate. One ends of the plurality of water flow pipes are fixedly connected to the inner walls of the two water spray nozzles. When the water flow is driven by the water pushing assembly to move from the cylinder body into the scraping block, the water flow will enter the inside of the scraping block from the top of the cylinder body. Through the limiting setting of the limiting plate, the water flow will flow into the plurality of water flow pipes under the push of the water pushing assembly, and finally be sprayed to the bottom of the valve block through the water spray nozzles, playing the role of water flow spraying. It should be noted here that the inner wall apertures of the plurality of water flow pipes are designed in a form of increasing and then decreasing, so that the incoming water flow can cooperate with the push of the water pushing assembly and fall onto the bottom of the valve block in a spraying form.

[0014] Preferably, the water pushing assembly includes a screw rod. The outer wall of the screw rod is rotatably connected to the inner wall of the cylinder body. A water pushing plate is threadedly connected to the outer wall of the cylinder body. The outer wall of the water pushing plate is slidably connected to the inner wall of the cylinder body. A turntable is fixedly installed at the bottom end of the screw rod. The turntable is rotatably connected to the inner wall of the cylinder body. Connecting rods are symmetrically fixedly installed on the outer wall of the turntable. One ends of the two connecting rods are respectively fixedly connected to the outer walls of the two indexing rods. When the hollow motor drives the scraping block to rotate through the indexing rod, the indexing rod drives the screw rod to rotate in the cylinder body through the connecting rod. When the screw rod rotates, in the form of screw transmission, the screw rod will drive the water pushing plate to move upward in the cylinder body, so as to push the water flow placed in the cylinder body, providing power for the water flow to be sprayed from the scraping block and playing the role of pushing the water flow to move.

[0015] Preferably, water pumping valves are symmetrically fixedly installed on the outer wall of the cylinder body. Filter pipes are fixedly installed at the water inlet ends of the two water pumping valves. Filter plates are fixedly installed on the inner walls of the two filter pipes. Scraping rods are fixedly installed on the outer walls of the two filter plates. Push seat plates are symmetrically fixedly installed on the outer walls of the two scraping rods. The two push seat plates are arranged in an alternating and symmetrical form. When the cleaning is completed, the hollow motor drives the scraping block to rotate in reverse, and the water pushing plate can move downward in the cylinder body. When the water pushing plate moves to the bottom of the cylinder body, at this time, stop the rotation of the hollow motor to complete the cleaning operation of the valve. When the water pushing plate moves to the bottom of the cylinder body, the water pumping valve operates, so as to pump the water flow placed in the water tank through the filter pipe, and finally pump the water flow into the cylinder body to provide water replenishment for the cylinder body. When the water flow flows into the cylinder body through the filter pipe, the filter plate filters the water flow to prevent the concrete residues dropped during cleaning in the water liquid from entering the cylinder body, playing the role of filtering the water liquid, and at the same time, the effect of recycling the water liquid placed in the water tank can also be achieved. When the water flow flows through the filter plate, through the pumping of the water pumping valve, the water flow will push the push seat plate to flow. When the push seat plate is pushed, the push seat plate will drive the scraping rod to scrape on the surface of the filter plate, so as to prevent the concrete residues in the water liquid from adhering to the filter plate when the water flow is pumped, affecting the movement of the water flow, and playing the role of ensuring the normal pumping of the water flow.

[0016] Preferably, the lifting component includes a shaft rod rotatably connected to the inner wall of the water tank. A push rod and a pry bar are fixedly installed on the outer wall of the shaft rod. One end of the pry bar can be in contact with the bottom of the support plate. A force - applying block is fixedly installed at the bottom of the electric slider, and the outer wall of the force - applying block can slide on the outer wall of the push rod. When the electric slider drives the baffle to move and open, the electric slider simultaneously drives the force - applying block to move. When the force - applying block moves, the force - applying block will push the push rod to move through the movement. When the push rod is pushed and moves, due to the setting of the shaft rod, when the push rod moves, the push rod will drive the pry bar to rotate through the shaft rod. When the pry bar rotates, one end of the pry bar will push the bottom of the support plate, thereby prying the bottom of the support plate. The support plate will move in the water tank, thereby driving the scraping block to move towards the bottom of the valve block. When the electric slider drives the baffle to be fully opened, at this time, the pry bar just drives the scraping block to contact the bottom of the valve block, so that when the two baffles move and open, the scraping block slowly moves to contact the bottom of the valve block, playing a role in driving the scraping block to contact the bottom of the valve block, providing a lifting contact effect for subsequent cleaning.

[0017] Preferably, a plurality of sliding shafts are fixedly installed at the bottom of the support plate, and a plurality of hollow shafts are fixedly installed at the bottom of the inner wall of the water tank. The outer walls of the plurality of sliding shafts are respectively slidably connected to the inner walls of the plurality of hollow shafts. A return spring is provided between the outer walls of the plurality of sliding shafts and the inner walls of the plurality of hollow shafts. When the support plate moves upward in the water tank, the sliding shaft will pull the return spring to move in the hollow shaft. When the cleaning operation is completed, the two electric sliders drive the baffle to move and reset, the push rod will lose the limit push, and the return spring will pull the sliding shaft to reset in the hollow shaft through the elastic force, and the support plate will move and reset in the water tank, and the scraping block will move downward from the bottom of the valve block, playing a role in resetting the position of the scraping block.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. For the adjustable flow control valve for shotcrete by casting described in the present invention, when the two baffles are opened, at this time, the lifting component drives the cleaning component to move upward from the water tank, so that the scraping block contacts the bottom of the valve block. When the two baffles are fully opened, the scraping block contacts the bottom of the valve block. Subsequently, the hollow motor is controlled to drive the ring shaft to rotate. When the ring shaft rotates, the ring shaft drives the scraping block to rotate at the bottom of the valve block through two indexing rods, thereby rotating and scraping the concrete attached to the bottom of the valve block, playing a role in scraping the concrete.

[0020] 2. For an adjustable flow control valve for cast-in-place shotcrete of the present invention, when the scraping block scrapes the bottom of the valve block, the water-pushing component in the cylinder operates, and the water flow in the cylinder will be driven by the water-pushing component and sprayed out from the water spray openings formed in the inner wall of the scraping block. Thus, when the scraping block scrapes the bottom of the valve block, the water flow sprays water on the bottom of the valve block, accelerating the cleaning speed and improving the cleaning effect at the same time.

[0021] 3. For an adjustable flow control valve for cast-in-place shotcrete of the present invention, when the hollow motor drives the scraping block to rotate through the rotating rod, the rotating rod drives the screw rod to rotate in the cylinder through the connecting rod. When the screw rod rotates, in the form of screw drive, the screw rod will drive the water-pushing disc to move upward in the cylinder, so as to push the water flow in the cylinder, providing power for the water flow to be sprayed out from the scraping block and playing a role in driving the water flow to move.

[0022] 4. For an adjustable flow control valve for cast-in-place shotcrete of the present invention, the water flow is extracted through the pumping valve to provide water replenishment operation for the cylinder. When the water flow flows into the cylinder through the filter pipe, the filter plate filters the water flow to prevent the concrete residues dropped during cleaning in the water liquid from entering the cylinder. At the same time, the effect of recycling the water liquid in the water tank can also be achieved. When the water flow flows through the pumping of the pumping valve, the water flow pushes the push seat plate to flow, and the push seat plate will drive the scraping rod to scrape on the surface of the filter plate, so as to prevent the concrete residues in the water liquid from adhering to the filter plate when the water flow is pumped, affecting the movement of the water flow.

[0023] 5. For an adjustable flow control valve for cast-in-place shotcrete of the present invention, the electric slider drives the force-applying block to move, and the force-applying block will push the push rod to move. Through the setting of the shaft rod, when the push rod moves, the push rod drives the pry bar to rotate through the shaft rod, and one end of the pry bar will push the bottom of the support plate, thus prying the bottom of the support plate. The support plate will move in the water tank, driving the scraping block to move towards the bottom of the valve block. When the electric slider drives the baffle to be fully opened, at this time, the pry bar just drives the scraping block to contact the bottom of the valve block, playing a role in driving the scraping block to contact the bottom of the valve block and providing the effect of lifting contact for subsequent cleaning.

[0037] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0038] Such as Figures 1 to 11As shown in the figure, an adjustable flow control valve for cast-in-place shotcrete according to an embodiment of the present invention includes a valve body 3. Pipes are symmetrically arranged on the outer wall of the valve body 3, and the pipes and the valve body 3 are connected by flange plates. An adjustment assembly is arranged inside the valve body 3 for adjusting and controlling the flow rate of concrete. A water tank 1 is fixedly installed at the bottom of the valve body 3. A liquid is arranged inside the water tank 1. An inlet and an outlet are respectively opened on both sides of the water tank 1. A cleaning assembly is arranged inside the water tank 1. The cleaning assembly includes a scraping block 11 and is used to drive the scraping block 11 to clean the inside of the valve body 3. Lifting assemblies are symmetrically arranged inside the water tank 1 and are used to drive the cleaning assembly to enter the valve body 3 from the water tank 1. The two lifting assemblies are respectively arranged on one side of the cleaning assembly;

[0039] Since there may be a certain amount of concrete inside the flow control valve at the end of the operation, these concretes will form hard blocks inside the valve, causing additional resistance and wear during the opening and closing process of the valve, accelerating the wear and aging of components, reducing the effective use times and overall service life of the valve;

[0040] During use, the concrete pipeline is connected to the valve body 3 by using a flange plate. The liquid is introduced into the water tank 1 through the inlet on one side of the water tank 1. When it is necessary to introduce concrete into the mold, the adjustment assembly is controlled to open, and the concrete can flow from the pipeline through the valve body 3 to the mold. When it is necessary to control the flow rate of concrete, by controlling the movement of the adjustment assembly inside the valve body 3, the flow control operation of the concrete can be realized. When the shotcrete operation inside the mold is completed, the adjustment assembly blocks and closes the concrete in the two pipelines inside the valve body 3. Subsequently, by controlling the lifting assembly to drive the cleaning assembly to enter the valve body 3 from the water tank 1, the cleaning assembly can drive the scraping block 11 to clean the inside of the valve body 3, thereby cleaning out the concrete placed inside the valve body 3, ensuring the cleanliness inside the valve body 3, and preventing the remaining concrete in the valve body 3 after the concrete spraying operation forms hard blocks through time settlement, causing additional resistance and wear during the opening and closing process of the valve, accelerating the wear and aging of components, and affecting the use effect and overall service life of the valve during the next use. It plays a role in automatically cleaning the valve when the valve operation is completed, ensuring and improving the service life and effect of the valve.

[0041] As Figures 3 to 4 shown in the figure, the adjustment assembly includes an adjustment motor 2 fixedly installed on the top of the valve body 3. The output end of the adjustment motor 2 is fixedly installed with a valve block 301, and the outer wall of the valve block 301 is slidably connected to the inner wall of the valve body 3;

[0042] When it is necessary to control the flow rate of concrete, the regulating motor 2 is driven to drive the valve block 301 to move. When it is necessary to increase the flow rate, the regulating motor 2 is driven to drive the valve block 301 to move upward in the valve body 3. When it is necessary to decrease the flow rate, vice versa, which plays a role in controlling and regulating the flow rate of concrete.

[0043] As Figures 5 to 6 shown, sliding rails 9 are symmetrically and fixedly installed on the inner wall of the water tank 1. The inner walls of the two sliding rails 9 are both slidably connected with electric sliders 901. Baffles 8 are fixedly installed on the outer walls of the two electric sliders 901. Both of the two baffles 8 are slidably connected with the bottom of the valve body 3;

[0044] When the concrete spraying operation ends, the regulating motor 2 is controlled to drive the valve block 301 to move to the bottom of the valve body 3. When the valve block 301 moves downward, the valve block 301 can push the concrete on the inner wall of the valve body 3 downward, thereby cleaning the inner wall of the valve body 3. When the valve block 301 moves to the bottom end of the valve body 3, at this time, the valve block 301 completely blocks the two pipelines, thereby achieving the effect of closing the valve. When the valve block 301 blocks and closes the pipeline, at this time, the electric slider 901 drives the baffle 8 to move in the sliding rail 9, and the baffle 8 will move and open from the bottom of the valve body 3. The concrete scraped off by the valve block 301 will fall into the water tank 1 from between the two baffles 8, which plays a role in opening and dropping the concrete, and also provides a path for the subsequent cleaning assembly to drive the scraping block 11 to clean the bottom of the valve block 301. It should be noted here that the initial positions of the two baffles 8 are placed directly below the valve block 301. When the concrete flows in the valve body 3, the two baffles 8 support the flow of the concrete.

[0045] As Figures 7 to 9 shown, the cleaning assembly further includes a support plate 5. The two sides of the support plate 5 are slidably connected with the inner wall of the water tank 1. A hollow motor 12 is fixedly installed on the top of the support plate 5. An annular shaft 15 is fixedly installed at the output end of the hollow motor 12. Rotating rods 18 are symmetrically and fixedly installed on the outer wall of the annular shaft 15. The tops of the two rotating rods 18 are both fixedly connected with the bottom of the scraping block 11. The two sides of the top of the scraping block 11 are both provided as inclined surfaces. The top of the scraping block 11 can be rotatably connected with the bottom of the valve block 301;

[0046] When the two baffles 8 are opened, at this time, the lifting assembly drives the cleaning assembly to move upward from the water tank 1, so that the scraping block 11 contacts the bottom of the valve block 301. When the two baffles 8 are completely opened, the scraping block 11 contacts the bottom of the valve block 301. Subsequently, the hollow motor 12 is controlled to drive the annular shaft 15 to rotate. When the annular shaft 15 rotates, the annular shaft 15 drives the scraping block 11 to rotate at the bottom of the valve block 301 through the two rotating rods 18, thereby rotating and scraping the concrete attached to the bottom of the valve block 301, which plays a role in scraping the concrete.

[0047] AsFigures 9 to 10 As shown, a retaining rod 13 is fixedly installed at the top of the support plate 5. A cylinder 7 is fixedly installed at the top of the retaining rod 13. The outer wall of the retaining rod 13 is rotatably connected to the inner wall of the ring shaft 15. The top of the cylinder 7 is rotatably connected to the inner wall of the scraping block 11. A water pushing component is arranged inside the cylinder 7. Water spraying ports 1101 are symmetrically formed on the inner wall of the scraping block 11.

[0048] When the scraping block 11 scrapes the bottom of the valve block 301, the water pushing component inside the cylinder 7 operates. The water placed inside the cylinder 7 will be driven by the water pushing component and sprayed out from the water spraying ports 1101 formed on the inner wall of the scraping block 11. Thus, when the scraping block 11 scrapes the bottom of the valve block 301, the water sprays on the bottom of the valve block 301, accelerating the cleaning speed and improving the cleaning effect at the same time.

[0049] As Figure 10 shown, a limiting plate 1102 is fixedly installed on the inner wall of the scraping block 11. A plurality of water flow pipes 1103 are fixedly installed at the top of the limiting plate 1102. One ends of the plurality of water flow pipes 1103 are fixedly connected to the inner walls of the two water spraying ports 1101.

[0050] When the water is driven by the water pushing component and moves from inside the cylinder 7 into the scraping block 11, the water will enter the inside of the scraping block 11 from the top of the cylinder 7. Through the limiting setting of the limiting plate 1102, the water will flow into the plurality of water flow pipes 1103 under the push of the water pushing component and finally be sprayed onto the bottom of the valve block 301 through the water spraying ports 1101, playing the role of water spraying. It should be noted here that the inner wall apertures of the plurality of water flow pipes 1103 are designed in a form of increasing and then decreasing, so that the incoming water can cooperate with the push of the water pushing component and fall onto the bottom of the valve block 301 in a spraying form.

[0051] As Figure 9 shown, the water pushing component includes a screw rod 701. The outer wall of the screw rod 701 is rotatably connected to the inner wall of the cylinder 7. A water pushing disk 702 is threadedly connected to the outer wall of the cylinder 7. The outer wall of the water pushing disk 702 is slidably connected to the inner wall of the cylinder 7. A turntable 17 is fixedly installed at the bottom end of the screw rod 701. The turntable 17 is rotatably connected to the inner wall of the cylinder 7. Connecting rods 16 are symmetrically fixedly installed on the outer wall of the turntable 17. One ends of the two connecting rods 16 are respectively fixedly connected to the outer walls of the two rotating rods 18.

[0052] When the hollow motor 12 drives the scraping block 11 to rotate through the rotating rod 18, the rotating rod 18 drives the screw rod 701 to rotate inside the cylinder 7 through the connecting rod 16. When the screw rod 701 rotates, in the form of screw drive, the screw rod 701 will drive the water pushing disk 702 to move upward inside the cylinder 7, so that the water pushing disk 702 pushes the water placed inside the cylinder 7, providing power for the water to be sprayed out from the scraping block 11 and playing the role of pushing the water to move.

[0053] As Figures 9 to 11 shown, water extraction valves 14 are symmetrically and fixedly installed on the outer wall of the cylinder body 7. Filter pipes 10 are fixedly installed at the water inlet ends of the two water extraction valves 14. Filter plates 1001 are fixedly installed on the inner walls of the two filter pipes 10. Scraping rods 1002 are fixedly installed on the outer walls of the two filter plates 1001. Push seat plates 1003 are symmetrically and fixedly installed on the outer walls of the two scraping rods 1002. The two push seat plates 1003 are arranged in a staggered and symmetrical form;

[0054] When the cleaning is completed, the hollow motor 12 drives the scraping block 11 to reverse, and the water pushing disc 702 can move downward in the cylinder body 7. When the water pushing disc 702 moves to the bottom of the cylinder body 7, at this time, stop the rotation of the hollow motor 12, and the cleaning operation of the valve can be completed. When the water pushing disc 702 moves to the bottom of the cylinder body 7, the water extraction valve 14 operates, so as to pump the water flow placed in the water tank 1 through the filter pipe 10, and finally pump the water flow into the cylinder body 7 to provide water replenishment operation for the cylinder body 7. When the water flow flows into the cylinder body 7 through the filter pipe 10, the filter plate 1001 filters the water flow to prevent the concrete residues dropped during cleaning in the water liquid from entering the cylinder body 7, achieving the effect of filtering the water liquid, and at the same time, it can also achieve the effect of recycling the water liquid placed in the water tank 1. When the water flow flows through the filter plate 1001, through the pumping of the water extraction valve 14, the water flow will push the push seat plate 1003 to flow. When the push seat plate 1003 is pushed, the push seat plate 1003 will drive the scraping rod 1002 to scrape on the surface of the filter plate 1001, so as to prevent the concrete residues in the water liquid from adhering to the filter plate 1001 when the water flow is pumped, affecting the movement of the water flow, and playing a role in ensuring the normal pumping of the water flow.

[0055] As Figures 6 to 7 shown, the lifting component includes a shaft rod 6. The shaft rod 6 is rotatably connected to the inner wall of the water tank 1. A push rod 601 and a pry bar 602 are fixedly installed on the outer wall of the shaft rod 6. One end of the pry bar 602 can be attached to the bottom of the support plate 5. A force applying block 902 is fixedly installed at the bottom of the electric slider 901. The outer wall of the force applying block 902 can be slidably connected to the outer wall of the push rod 601;

[0056] When the electric slider 901 drives the baffle 8 to move and open, the electric slider 901 simultaneously drives the force-applying block 902 to move. When the force-applying block 902 moves, the force-applying block 902 will push the push rod 601 to move through the movement. When the push rod 601 is pushed and moves, due to the setting of the shaft rod 6, when the push rod 601 moves, the push rod 601 will drive the pry bar 602 to rotate through the shaft rod 6. When the pry bar 602 rotates, one end of the pry bar 602 will push the bottom of the support plate 5, thereby prying the bottom of the support plate 5. The support plate 5 will move in the water tank 1, thereby driving the scraping block 11 to move towards the bottom of the valve block 301. When the electric slider 901 drives the baffle 8 to be completely opened, at this time, the pry bar 602 just drives the scraping block 11 to contact the bottom of the valve block 301. Thus, when the two baffles 8 move and open, the scraping block 11 slowly moves to contact the bottom of the valve block 301, playing a role in driving the scraping block 11 to contact the bottom of the valve block 301, providing a lifting contact effect for subsequent cleaning.

[0057] As Figure 8 shown, a plurality of sliding shafts 402 are fixedly installed at the bottom of the support plate 5, and a plurality of hollow shafts 4 are fixedly installed at the bottom of the inner wall of the water tank 1. The outer walls of the plurality of sliding shafts 402 are respectively slidably connected to the inner walls of the plurality of hollow shafts 4. A return spring 401 is provided between the outer walls of the plurality of sliding shafts 402 and the inner walls of the plurality of hollow shafts 4;

[0058] When the support plate 5 moves upward in the water tank 1, the sliding shaft 402 will pull the return spring 401 to move in the hollow shaft 4. When the cleaning operation is completed, the two electric sliders 901 drive the baffle 8 to move and reset, and the push rod 601 will lose the limit push. The return spring 401 will pull the sliding shaft 402 to reset in the hollow shaft 4 through the elastic force, and the support plate 5 will move and reset in the water tank 1, and the scraping block 11 will move downward from the bottom of the valve block 301, playing a role in resetting the position of the scraping block 11.

[0059] Working principle: During use, the concrete pipe is connected to the valve body 3 by using a flange. Water liquid is introduced into the water tank 1 through the water inlet on one side of the water tank 1. When it is necessary to introduce concrete into the module, the control and adjustment assembly is controlled to open, and the concrete can flow from the pipe through the valve body 3 to the module. When it is necessary to control the flow rate of the concrete, by controlling the movement of the control and adjustment assembly in the valve body 3, the flow control operation of the concrete can be realized. When the shotcrete operation in the module is completed, the adjustment assembly plugs and closes the concrete in the two pipes in the valve body 3. Subsequently, by controlling the lifting assembly to drive the cleaning assembly to enter the valve body 3 from the water tank 1, the cleaning assembly can drive the scraping block 11 to clean the inside of the valve body 3, thereby cleaning out the concrete placed in the valve body 3, ensuring the cleanliness of the valve body 3, preventing the valve body 3 from remaining with concrete when the concrete spraying operation is completed. Through the static placement of time, this concrete forms hard blocks in the valve body 3, causing additional resistance and wear when the valve is opened and closed, accelerating the wear and aging of the components, and affecting the use effect and overall service life of the valve when it is used next time. It plays a role in automatically cleaning the valve when the valve operation is completed, ensuring and improving the service life and effect of the valve;

[0060] When it is necessary to control the flow rate of the concrete, the drive adjustment motor 2 is driven to drive the valve block 301 to move. When it is necessary to increase the flow rate, the drive adjustment motor 2 drives the valve block 301 to move upward in the valve body 3. When it is necessary to decrease the flow rate, it is the opposite, playing a role in controlling and adjusting the flow rate of the concrete;

[0061] When the shotcrete operation is completed, the control adjustment motor 2 is controlled to drive the valve block 301 to move to the bottom of the valve body 3. When the valve block 301 moves downward, the valve block 301 can push the concrete on the inner wall of the valve body 3 downward, thereby cleaning the inner wall of the valve body 3. When the valve block 301 moves to the bottom end of the valve body 3, at this time, the valve block 301 completely blocks the two pipes, thereby achieving the effect of closing the valve. When the valve block 301 blocks and closes the pipe, at this time, the electric slider 901 drives the baffle 8 to move in the slide rail 9, and the baffle 8 will move and open from the bottom of the valve body 3. The concrete scraped off by the valve block 301 will fall into the water tank 1 from between the two baffles 8, playing a role in opening and closing and dropping the concrete, and also providing a path for the subsequent cleaning assembly to drive the scraping block 11 to clean the bottom of the valve block 301. It should be noted here that the initial positions of the two baffles 8 are placed directly below the valve block 301. When the concrete flows in the valve body 3, the two baffles 8 support the flow of the concrete;

[0062] When the two baffles 8 are opened, the lifting component drives the cleaning component to move upward from the water tank 1 at this time, so that the scraping block 11 contacts the bottom of the valve block 301. When the two baffles 8 are fully opened, the scraping block 11 touches the bottom of the valve block 301. Subsequently, the hollow motor 12 is controlled to drive the ring shaft 15 to rotate. When the ring shaft 15 rotates, the ring shaft 15 drives the scraping block 11 to rotate on the bottom of the valve block 301 through the two indexing rods 18, so as to rotate and scrape the concrete attached to the bottom of the valve block 301, playing the role of scraping the concrete;

[0063] When the scraping block 11 scrapes the bottom of the valve block 301, the water-pushing component in the cylinder body 7 operates, and the water flow placed in the cylinder body 7 will be driven by the water-pushing component to spray out from the water spray ports 1101 opened on the inner wall of the scraping block 11. Thus, when the scraping block 11 scrapes the bottom of the valve block 301, the water flow sprays water on the bottom of the valve block 301, accelerating the cleaning speed and improving the cleaning effect at the same time;

[0064] When the water flow is driven by the water-pushing component to move from the cylinder body 7 into the scraping block 11, the water flow will enter the inside of the scraping block 11 from the top of the cylinder body 7. Through the limiting setting of the limiting plate 1102, the water flow will flow into the multiple water flow pipes 1103 under the push of the water-pushing component and finally be sprayed onto the bottom of the valve block 301 through the water spray ports 1101, playing the role of water flow spraying. It should be noted here that the inner wall apertures of the multiple water flow pipes 1103 are designed in a form of increasing and then decreasing, so that the incoming water flow can cooperate with the push of the water-pushing component and fall onto the bottom of the valve block 301 in a spraying form;

[0065] When the hollow motor 12 drives the scraping block 11 to rotate through the indexing rod 18, the indexing rod 18 drives the screw rod 701 to rotate in the cylinder body 7 through the connecting rod 16. When the screw rod 701 rotates, in the form of screw drive, the screw rod 701 will drive the water-pushing disc 702 to move upward in the cylinder body 7, so that the water-pushing disc 702 pushes the water flow placed in the cylinder body 7, providing power for the water flow to spray out from the scraping block 11 and playing the role of pushing the water flow to move;

[0066] When the cleaning is completed, the hollow motor 12 drives the scraping block 11 to reverse, and the water pushing plate 702 can move downward in the cylinder body 7. When the water pushing plate 702 moves to the bottom of the cylinder body 7, at this time, stop the rotation of the hollow motor 12, and the cleaning operation of the valve can be completed. When the water pushing plate 702 moves to the bottom of the cylinder body 7, the pumping valve 14 operates, so as to pump the water flow placed in the water tank 1 through the filter pipe 10, and finally pump the water flow into the cylinder body 7 to provide a water replenishment operation for the cylinder body 7. When the water flow flows into the cylinder body 7 through the filter pipe 10, the filter plate 1001 filters the water flow to prevent the concrete residues falling off during cleaning in the water liquid from entering the cylinder body 7, achieving the effect of filtering the water liquid, and at the same time, it can also achieve the effect of recycling the water liquid placed in the water tank 1. When the water flow flows through the filter plate 1001, through the pumping of the pumping valve 14, the water flow will push the push seat plate 1003 to flow. When the push seat plate 1003 is pushed, the push seat plate 1003 will drive the scraping rod 1002 to scrape on the surface of the filter plate 1001, so as to prevent the concrete residues in the water liquid from adhering to the filter plate 1001 when the water flow is pumped, affecting the movement of the water flow, and playing a role in ensuring the normal pumping of the water flow;

[0067] When the electric slider 901 drives the baffle 8 to move and open, the electric slider 901 simultaneously drives the force applying block 902 to move. When the force applying block 902 moves, the force applying block 902 will push the push rod 601 to move through the movement. When the push rod 601 is pushed and moves, through the setting of the shaft rod 6, when the push rod 601 moves, the push rod 601 will drive the pry bar 602 to rotate through the shaft rod 6. When the pry bar 602 rotates, one end of the pry bar 602 will push the bottom of the support plate 5, so as to pry the bottom of the support plate 5. The support plate 5 will move in the water tank 1, thereby driving the scraping block 11 to move towards the bottom of the valve block 301. When the electric slider 901 drives the baffle 8 to open completely, at this time, the pry bar 602 just drives the scraping block 11 to contact the bottom of the valve block 301, so that when the two baffles 8 move and open, the scraping block 11 slowly moves to contact the bottom of the valve block 301, playing a role in driving the scraping block 11 to contact the bottom of the valve block 301, and providing a lifting contact effect for the subsequent cleaning;

[0068] When the support plate 5 moves upward in the water tank 1, the sliding shaft 402 will pull the return spring 401 to move in the hollow shaft 4. When the cleaning operation is completed, the two electric sliders 901 drive the baffle 8 to move and reset, the push rod 601 will lose the limit push, the return spring 401 will pull the sliding shaft 402 to reset in the hollow shaft 4 through the elastic force, the support plate 5 will move and reset in the water tank 1, and the scraping block 11 will move downward from the bottom of the valve block 301, playing a role in resetting the position of the scraping block 11.
