[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a water level regulating device for a continuous flow cement tank, including a buried pipe 6, an outer pipe 7, and an inner pipe 8. For example... Figure 1 , Figure 2 and Figure 3 As shown, the buried pipe 6 is fixedly connected to the cement tank 1, which is fixedly placed on two mounting bases. A support block is fixedly assembled between the two mounting bases, and the buried pipe 6 passes through the support block and is fixedly connected to it. The connection between the buried pipe 6 and the cement tank 1 is located at the bottom of the cement tank 1, and a filter screen 9 is fixedly assembled at the connection between the buried pipe 6 and the cement tank 1 to filter nutrients in the water and prevent nutrient loss.

[0027] The buried pipe 6 is fixedly connected to the vertically placed outer pipe 7 at the pipe opening away from the cement pool 1. A support base 5 is fixedly connected to the side of the cement pool 1, and a water pump 2 is fixedly mounted on the support base 5. The inlet of the water pump 2 is connected to a water source, and the outlet of the water pump 2 faces into the water pool 1, for adding water to the water pool 1. The outer pipe 7 passes through the support base 5 and is fixedly connected to the support base 5 for fixing the outer pipe 7.

[0028] like Figure 4 As shown, a water outlet hole is cut into the body of the outer pipe 7. The opening of the water outlet hole is opened radially along the outer pipe 7, and the water outlet hole is cut from top to bottom along the axial direction of the outer pipe 7. A water level line is engraved on the body of the outer pipe 7 along the axial direction of the outer pipe 7. The water level line is not drawn or marked in the diagram. The water level line is located on the side of the water outlet hole and corresponds to the water outlet hole, which facilitates the determination of the water level.

[0029] like Figure 5 As shown, the inner tube 8 is a semi-circular arc-shaped half-section tube. An outlet is cut out of the inner tube 8, and the orifice of the outlet is opened along the radial direction of the inner tube 8. The outlet pipe 13 is welded and fixed on the outer curved surface of the inner tube 8. The outlet pipe 13 is connected to the outlet of the inner tube 8 and is inclined downward away from the outlet of the inner tube 8.

[0030] like Figure 4 , Figure 6 and Figure 7 As shown, the inner tube 8 is coaxially inserted into the outer tube 7 and has a sealing sliding fit with the outer tube 7. The water outlet pipe 13 on the inner tube 8 passes through the water outlet hole of the outer tube 7 and can slide up and down within the water outlet hole. The water outlet pipe 13 has a limiting sliding fit with the outer tube 7. The bottom of the inner tube 8 is lower than the bottom of the water outlet hole on the outer tube 7, ensuring that no water will flow out of the water outlet hole of the outer tube 7 during the up and down sliding of the inner tube 8 within the outer tube 7.

[0031] The bottom of the outer tube 7 is coaxially fixedly connected to the relief tube. The inner tube 8 is inserted into the relief tube and is sealed and slidably fitted with the relief tube. The bottom of the relief tube is sealed with a plug by a snap or thread. When a lot of foreign matter settles in the relief tube, the plug can be opened to discharge the foreign matter in the relief tube.

[0032] A piston 10 is fixedly connected to the top of the inner tube 8, and the piston 10 is in a sealing sliding fit with the outer tube 7. A fixed plate is fixedly connected to the top of the outer tube 7, and an adjusting component is mounted on the fixed plate. The adjusting component is driven by the piston 10 and is used to drive the piston 10 to slide up and down inside the outer tube 7. The adjusting component includes a handwheel 11 and a threaded rod 12. The threaded rod 12 passes vertically downward along the axial direction of the outer tube 7 through the fixed plate and is threadedly connected to the fixed plate. The bottom of the threaded rod 12 rotates with the piston 10, and the top of the threaded rod 12 is coaxially fixedly connected to the handwheel 11.

[0033] A switching assembly is installed inside the piston 10. The water pump 2 is electrically connected to the switching assembly, which is in turn electrically connected to a power source. The power source is not shown or indicated in the diagram. The switching assembly includes two electrode contacts 16. The two electrode contacts 16 are horizontally opposed to each other along the radial direction of the outer tube 7. Two grooves are carved into the piston 10, each corresponding to one of the two electrode contacts 16. Each electrode contact 16 is slidably fitted within its corresponding groove. One electrode contact 16 is electrically connected to the water pump 2, and the other electrode contact 16 is fixedly connected to the power source.

[0034] A control component is mounted on the piston 10. The input end of the control component is in contact with the water flow in the inner tube 8, and the output end of the control component is in drive with the two electrode contacts 16. The water flow drives the control component to control the contact and disengagement of the two electrode contacts 16. The control component includes a float plate 15 as the input end, a plug rod 14 as the output end, and two second springs 19. Each of the two electrode contacts 16 has a second spring 19 fixedly connected to its opposite ends. Each second spring 19 is located in a groove where the connected electrode contact 16 is located, and each second spring 19 is arranged along the sliding direction of the connected electrode contact 16. The end of each second spring 19 away from the connected electrode contact 16 is fixedly connected to the piston 10 to drive the two electrode contacts 16 into contact.

[0035] A slot is drilled axially from the piston 10 along the outer tube 7. The slot is rectangular and located between two sliding grooves, which communicate with each other. A rod 14 is a rectangular rod that matches the slot. The rod 14 is inserted into the slot and slides in a limiting engagement with the piston 10. The rod 14 is an insulator with a wedge-shaped top. The top of the rod 14 contacts the two electrode contacts 16 in a contact-transmission engagement, used to push the two electrode contacts 16 away from contact. The bottom of the rod 14 is fixedly connected to a float plate 15. The float plate 15 contacts the water flow in the inner tube 8 in a contact-transmission engagement, used to push the float plate 15 upwards along the inner tube 8.

[0036] A cavity is carved out inside the piston 10, communicating with the slot. A limiting plate 18 and a first spring 17 are placed inside the cavity. The limiting plate 18 is fixedly connected to the insertion rod 14. The first spring 17 is sleeved on the insertion rod 14, with one end of the first spring 17 fixedly connected to the piston 10 and the other end of the first spring 17 fixedly connected to the limiting plate 18. The first spring 17 is used for resetting the insertion rod 14.

[0037] like Figure 1 As shown, the end of the support base 5 furthest from the cement pool 1 is fixedly connected to the water receiving tank 3, and the top of the water receiving tank 3 is open. The outlet pipe 13, furthest from the inner pipe 8, faces the water receiving tank 3. A baffle 4 is fixedly mounted on the top of the water receiving tank 3, and a guide groove is provided on the baffle 4. The outlet pipe 13 passes through the guide groove and slides within the guide groove. The outlet pipe 13 and the baffle 4 are in a limiting sliding fit.

[0038] The water tank 3 is fixedly connected to the connecting pipe, which can be connected to the purifier or to the land, etc., to achieve wastewater utilization.

[0039] Working principle: The power supply is not turned on before use.

[0040] In use, first manually turn the handwheel 11, which drives the threaded rod 12 to rotate. During rotation, the threaded rod 12 moves up and down, simultaneously causing the piston 10 to slide up and down along the outer tube 7. The piston 10 then drives the inner tube 8 to slide up and down along the outer tube 7, and the outlet on the inner tube 8 moves up and down with it. During this process, observe the water level line on the outer tube 7. Stop turning when the outlet on the inner tube 8 reaches the predetermined water level line.

[0041] Next, the power is turned on. Since the two electrode contacts 16 are in contact, the water pump 2 is powered on and starts, adding water to the cement tank 1. The water added to the cement tank 1 flows sequentially into the buried pipe 6 and the outer pipe 7. As the water level in the cement tank 1 rises, the water in the outer pipe 7 first contacts the float plate 15 via the inner pipe 8. Then, under the action of buoyancy, the water flow pushes the float plate 15 upwards. The float plate 15 drives the insertion rod 14 to slide upwards along the slot, and the top of the insertion rod 14 gradually approaches the two electrode contacts 16. At the same time, the insertion rod 14 drives the limiting plate 18 to compress the first spring 17.

[0042] When the water level in the outer pipe 7 reaches the outlet of the inner pipe 8, the water level in the cement pool 1 reaches the predetermined value due to the principle of communicating vessels. At the same time, the wedge-shaped end at the top of the insertion rod 14 pushes the two electrode contacts 16 apart, the two electrode contacts 16 are out of contact, the two second springs 19 are compressed, and the water pump 2 is turned off.

[0043] When the water level needs to be lowered after a period of aquaculture, turn the handwheel 11 again. The handwheel 11 drives the threaded rod 12 to rotate, and the threaded rod 12 drives the piston 10 to move down. The piston 10 drives the inner tube 8 to slide down. The outlet of the inner tube 8 moves with the inner tube 8 and is lower than the current water level. After that, the water in the outer tube 7 flows to the water receiving tank 3 through the outlet pipe 13 on the inner tube 8. The water level in the outer tube 7 decreases at the same time as the water level in the cement pool 1 decreases.

[0044] During this process, since the float 15 always floats on the water surface and remains stationary relative to the inner tube 8 under the action of the first spring 17, the two electrode contacts 16 are always in a disengaged state, and the water pump 2 is always shut off.

[0045] When the water level needs to be raised after a period of aquaculture, turn the handwheel 11 again. The handwheel 11 drives the threaded rod 12 to rotate, which in turn drives the piston 10 to move upward. The piston 10 then drives the inner tube 8 to slide upward. The outlet of the inner tube 8 moves with the inner tube 8 and is higher than the current water level. During this process, the float 15 comes into contact with the water surface. Under the action of the first spring 17 and gravity, the float 15 moves downward relative to the inner tube 8, and the float 15 drives the insert rod 14 to slide down the slot relative to the inner tube 8. The insert rod 14 gradually disengages from the two electrode contacts 16, and after disengagement, under the elastic force of the two second springs 19, the two electrode contacts 16 approach each other and make contact. The water pump 2 is energized and adds water to the cement tank 1. When the water level reaches the set value again, the insert rod 14 pushes the two electrode contacts 16 away again, and the water pump 2 is turned off.

[0046] During the aquaculture process, when the water level in the cement tank 1 drops due to external factors, the outer pipe 7 also drops synchronously with the water level in the cement tank 1. During this process, the float 15 initially floats on the water surface and moves downwards with the water. As the water level continues to drop, the float 15 loses contact with the water surface. As the float 15 moves downwards with the water surface, the first spring 17 pushes the limiting plate 18. The limiting plate 18 causes the insertion rod 14 to slide down the slot and gradually separate from the two electrode contacts 16. After separation, the two electrode contacts 16 contact under the action of the two second springs 19, energizing the water pump 2 and adding water to the cement tank 1. When the water level reaches the set level again, the insertion rod 14 pushes the two electrode contacts 16 apart again, and the water pump 2 shuts off. This ensures a stable water level.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
