Description

Technical Field

[0001] This utility model relates to the field of water level control technology, and in particular to a float water level controller. Background Technology

[0002] The existing methods for controlling water levels in reservoirs, aquaculture ponds, and sewage treatment ponds are based on float valves. These valves consist of a float and a valve body. The float moves up and down with the water surface to control the opening and closing of the valve body, ultimately controlling the water level within a certain range. However, the valve body of the existing float valve needs to be opened and closed frequently, which can easily lead to the failure of the valve body's seal. Once the seal of the existing float valve body fails, the float valve will be in a normally open state, which can easily lead to excessively high water levels and overflow. Utility Model Content

[0003] To address the lack of secondary water-blocking function in existing float valves, this invention proposes a float level controller with secondary water-blocking function, which will not cause overflow even if there is water leakage between the lower baffle and the lower sealing part.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A float-type water level controller includes an inlet pipe, a connecting plate, a limiting pipe, a float, a transmission structure, an upper baffle, and an upper sealing part. The limiting pipe is vertically fixed to one side of the inlet pipe through the connecting plate. The float is disposed in the limiting pipe. Both the limiting pipe and the inlet pipe have clearance grooves on their sides. The transmission structure drives the float and the upper baffle through the clearance grooves. The upper baffle is disposed in the inlet pipe and hinged to it. The upper sealing part is disposed below the upper baffle and the clearance grooves and is fixedly connected to the inlet pipe along its inner circumference. The water level controller also includes an elastic rod, a lower baffle, and a lower sealing part. The lower baffle is disposed below the lower baffle and hinged to the inlet pipe. The elastic rod is hinged between the upper baffle and the lower baffle. The lower sealing part is disposed below the lower baffle and is fixedly connected to the inlet pipe along its inner circumference.

[0006] The water level controller has a single-block mode and a double-block mode. In the single-block mode, the lower baffle covers the upper side of the lower sealing part, and the upper baffle is separated from the upper sealing part. In the double-block mode, the lower baffle and the upper baffle cover the lower sealing part and the upper sealing part, respectively.

[0007] With the above settings, in single-block mode, after water leaks between the lower baffle and the lower sealing part, the water level controller will then switch to double-block mode, where the upper baffle and the upper sealing part block the water to prevent the water level from rising further, thereby achieving the effect of preventing overflow.

[0008] Furthermore, the transmission structure includes a fixed rod, a first movable rod, and a second movable rod. The lower end of the fixed rod is fixedly connected to the float, the upper end of the fixed rod is hinged to one end of the first movable rod, the other end of the first movable rod passes through a clearance groove and is hinged to one end of the second movable rod, the middle part of the first movable rod is hinged to the connecting plate, and the other end of the second movable rod is hinged to the upper side of the upper baffle.

[0009] With the above configuration, the float is connected to the upper baffle via a fixed rod, a first movable rod, and a second movable rod.

[0010] Furthermore, the upper sealing part includes an upper boss and an upper sealing ring. The upper boss is fixedly connected to the water inlet pipe along its inner circumference. The side of the upper baffle near the relief groove is hinged to the upper side of the upper boss. An upper mounting groove is provided on the upper side of the upper boss along its circumference, and the upper sealing ring is installed in the upper mounting groove.

[0011] Furthermore, the lower sealing part includes a lower boss and a lower sealing ring. The lower boss is fixedly connected to the water inlet pipe along its inner circumference. The side of the lower baffle near the relief groove is hinged to the upper side of the lower boss. A lower mounting groove is provided on the upper side of the lower boss along its circumference, and the lower sealing ring is installed in the lower mounting groove.

[0012] Furthermore, the elastic rod includes a sleeve, a connecting rod, and a spring. The lower end of the sleeve is hinged to the lower baffle, the lower end of the connecting rod is slidably connected to the upper end of the sleeve, the spring is disposed in the sleeve and connected to the lower end of the connecting rod, and the upper end of the connecting rod is hinged to the upper baffle.

[0013] Furthermore, in the double-block mode, both the upper and lower baffles are perpendicular to the water inlet pipe, and the elastic rod is vertically positioned between the upper and lower baffles.

[0014] Furthermore, both the float and the limiting tube are made of plastic.

[0015] The above settings improve the corrosion resistance of the float and the limiting tube, thereby enhancing the stability of the water level controller. Attached Figure Description

[0020] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0021] like Figures 1 to 4 A float-type water level controller includes an inlet pipe 3, a connecting plate 4, a limiting pipe 5, a float 6, a transmission structure 7, an upper baffle 8, and an upper sealing part 9. The limiting pipe 5 is vertically fixed to one side of the inlet pipe 3 via the connecting plate 4. The float 6 is disposed in the limiting pipe 5. Both the limiting pipe 5 and the inlet pipe 3 have clearance grooves 10 on their sides. The transmission structure 7 drives the float 6 to the upper baffle 8 via the clearance grooves 10. The upper baffle 8 is disposed in the inlet pipe 3 and is connected to the upper sealing part 9. The water inlet pipe 3 is hinged, and the upper sealing part 9 is located on the lower side of the upper baffle 8 and the relief groove 10, and is fixedly connected to the water inlet pipe 3 along the inner circumference. The water level controller also includes an elastic rod 11, a lower baffle 12 and a lower sealing part 13. The lower baffle 12 is located on the lower side of the lower baffle 12 and is hinged to the water inlet pipe 3. The elastic rod 11 is hinged between the upper baffle 8 and the lower baffle 12. The lower sealing part 13 is located on the lower side of the lower baffle 12 and is fixedly connected to the water inlet pipe 3 along the inner circumference.

[0022] The water level controller has a single-block mode and a double-block mode. In the single-block mode, the lower baffle 12 covers the upper side of the lower sealing part 13, and the upper baffle 8 is separated from the upper sealing part 9. In the double-block mode, the lower baffle 12 and the upper baffle 8 cover the lower sealing part 13 and the upper sealing part 9 respectively.

[0023] With the above settings, in the single-block mode, after water leaks between the lower baffle 12 and the lower sealing part 13, the water level controller will then switch to the double-block mode, where the upper baffle 8 and the upper sealing part 9 block the water to prevent the water level from rising further, thereby achieving the effect of preventing overflow.

[0024] Specifically, the inlet pipe 3 is basically a circular pipe structure, installed vertically in the water tank. The lower end of the inlet pipe 3 is connected to the municipal water pipe or other water pipes. The limiting pipe 5 is heat-fused to one side of the inlet pipe 3 through the connecting plate 4. The inner diameter of the limiting pipe 5 is basically 1.2 times that of the float 6. While limiting the left and right movement range of the float 6, the friction between the float 6 and the limiting pipe 5 is small, so the float 6 floats on the water surface and floats up and down with the water surface. When the float 6 moves upward, the float 6 drives the upper baffle 8 to rotate downward through the transmission structure 7. The upper baffle 8 drives the lower baffle through the elastic rod 11. When the float 6 moves downward, it drives the upper baffle 8 to rotate upward through the transmission structure 7. The upper baffle 8 then drives the lower baffle 12 to rotate upward through the elastic rod 11. When the water level drops, the float 6 moves downward under gravity, and the upper baffle 8 and lower baffle 12 rotate upward. Water in the water pipe is output to the pool through the inlet pipe 3, lower sealing part 13, lower baffle 12, upper sealing part 9, and upper baffle 8. When the water level rises, it drives the float 6 to move upward, and the upper baffle 8 and lower baffle 12 rotate downward. The lower baffle 12 covers the lower sealing part 13. Figure 2When the water level controller is in single-block mode, the elastic rod 11 presses the lower baffle 12 against the lower sealing part 13 through its elasticity, the water inlet pipe 3 stops flowing out, and the water level stops rising. When the water level drops, the float 6 descends, and the upper baffle 8 and lower baffle 12 rotate upward, allowing water to flow out of the water inlet pipe 3 again. Initially, the seal between the lower sealing part 13 and the lower baffle 12 is intact, and the water level controller switches back and forth between single-block mode and water flow mode. During this process, the upper sealing part 9 and the upper baffle 8 will not experience much wear. If the seal between the lower baffle 12 and the lower sealing part 13 fails and leakage occurs, the water level in the pool will continue to rise, and the float 6 will experience increased buoyancy. The float 6 exerts greater downward pressure on the upper baffle 8 through the transmission structure 7, causing the upper baffle 8 to continue rotating downwards. The elastic rod 11 contracts, increasing the pressure on the lower baffle 12. If the leakage between the lower baffle 12 and the lower sealing part 13 stops at this time, the water level will stop rising. If the leakage between the lower baffle 12 and the lower sealing part 13 continues, the water level will continue to rise, and the upper baffle 8 will continue to rotate downwards until it covers the upper sealing part 9. At this time, the water is blocked by the upper baffle 8 and the upper sealing part 9, and the water level controller is in double-blocking mode to prevent overflow. When the water level drops, the float 6 drops, causing the upper baffle 8 and the lower baffle 12 to rotate upwards, and the water inlet pipe 3 starts to fill with water again.

[0025] As one implementation, the transmission structure 7 includes a fixed rod 71, a first movable rod 72 and a second movable rod 73. The lower end of the fixed rod 71 is fixedly connected to the float 6, the upper end of the fixed rod 71 is hinged to one end of the first movable rod 72, the other end of the first movable rod 72 passes through the clearance groove 10 and is hinged to one end of the second movable rod 73, the middle part of the first movable rod 72 is hinged to the connecting plate 4, and the other end of the second movable rod 73 is hinged to the upper side of the upper baffle 8.

[0026] With the above configuration, the float 6 is connected to the upper baffle 8 via the fixed rod 71, the first movable rod 72, and the second movable rod 73.

[0027] In this application, the float 6 rotates the first movable rod up and down via the fixed rod 71. The clearance groove ensures that the first movable rod will not interfere with the limiting pipe and the water inlet pipe when it rotates. When the first movable rod rotates, it pulls the upper baffle to rotate up and down via the second movable rod.

[0028] As one implementation, the upper sealing part 9 includes an upper boss 91 and an upper sealing ring 92. The upper boss 91 is fixedly connected to the water inlet pipe 3 along its inner circumference. The upper baffle 8 is hinged to the upper side of the upper boss 91 on the side near the relief groove 10. An upper mounting groove is provided on the upper side of the upper boss 91 along its circumference, and the upper sealing ring 92 is installed in the upper mounting groove.

[0029] When the upper baffle 8 of this application covers the upper sealing part 9 from the bottom, the lower side of the upper baffle 8 is pressed against the upper boss 91 and the upper sealing ring 92, and the upper sealing ring 92 prevents water leakage between the upper baffle 8 and the upper boss 91.

[0030] As one implementation, the lower sealing part 13 includes a lower boss 131 and a lower sealing ring 132. The lower boss 131 is fixedly connected to the water inlet pipe 3 along its inner circumference. The lower baffle 12 is hinged to the upper side of the lower boss 131 on the side near the relief groove 10. A lower mounting groove is provided on the upper side of the lower boss 131 along the circumferential direction. The lower sealing ring 132 is installed in the lower mounting groove.

[0031] When the lower baffle 12 of this application covers the upper side of the lower sealing part 13 downwards, the lower side of the lower baffle 12 is pressed against the lower boss 131 and the lower sealing ring 132, and the lower sealing ring 132 prevents water leakage between the lower baffle 12 and the lower boss 131.

[0032] In one implementation, the elastic rod 11 includes a sleeve 111, a connecting rod 112, and a spring 113. The lower end of the sleeve 111 is hinged to the lower baffle 12, the lower end of the connecting rod 112 is slidably connected to the upper end of the sleeve 111, the spring 113 is disposed in the sleeve 111 and connected to the lower end of the connecting rod 112, and the upper end of the connecting rod 112 is hinged to the upper baffle 8.

[0033] In this application, the upper end of the spring 113 is fixedly connected to the lower end of the connecting rod 112, and the lower end of the spring 113 is fixedly connected to the bottom of the sleeve 111. When the upper baffle 8 moves upward, the upper baffle 8 drives the lower baffle 12 to rotate upward through the connecting rod 112, the spring 113, and the sleeve 111. When the lower baffle 12 rotates downward, the upper baffle 8 presses down on the lower baffle 12 through the connecting rod 112, the spring 113, and the sleeve 111. Under the elastic force of the spring 113, the lower baffle 12 is tightly covered on the lower sealing part 13. The upper baffle 8 continues to rotate downward, and the spring 113 continues to compress until the upper baffle 8 is tightly covered on the upper sealing part 9.

[0034] As one implementation method, in the double-block mode, both the upper baffle 8 and the lower baffle 12 are perpendicular to the water inlet pipe 3, and the elastic rod 11 is vertically set between the upper baffle 8 and the lower baffle 12.

[0035] As one implementation method, both the float 6 and the limiting tube 5 are made of plastic.

[0036] The above settings improve the corrosion resistance of the float 6 and the limiting tube 5, thereby enhancing the stability of the water level controller.

[0037] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
