Description

Technical Field

[0001] The utility model relates to the technical field of water tank drainage adjustment, in particular to a device capable of adjusting the drainage of a high-level water tank. Background Art

[0002] When the valveless filter is working, the raw water is sent from the high-level water tank into the filter chamber through the water inlet pipe, and filtered from top to bottom through the filter layer. Clean water enters the clean water tank of the valveless filter from the connecting pipe for storage. After the clean water tank is full, the water flows into the rear clean water tank through the outlet pipe. The filter layer continuously intercepts suspended matter, causing the resistance of the filter layer to gradually increase, thereby causing the water level in the siphon riser to continue to rise. When the water level reaches the outlet of the siphon auxiliary pipe, the water falls from the pipe and passes through the air extraction pipe to take away the air in the siphon down pipe. When the vacuum reaches a certain value, the siphon effect occurs. At this time, the water in the clean water tank of the valveless filter passes through the filter layer from bottom to top to backwash the filter layer. When the water level of the clean water tank of the valveless filter drops to the outlet of the siphon destruction pipe, air enters the siphon pipe to destroy the siphon effect. The valveless filter ends backwashing and enters the next cycle of work.

[0003] During the use of valveless filters, some valveless filters are designed to process a large amount of water, but the actual water intake is 1 / 2 or less of the treated water. When the filter chamber of the valveless filter is blocked during backwashing, the siphon pipe discharges water and takes away part of the water from the water inlet pipe. At this time, the water level in the high-level water tank drops rapidly because the water intake does not match the designed water volume, and eventually the water inlet inhales air to destroy the siphon, causing the equipment to fail to backwash normally.

[0004] Therefore, a control device is needed to facilitate adjusting the discharge volume of the high-level water tank. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 , the utility model provides a technical solution:

[0024] A device capable of adjusting the discharge volume of a high-level water tank comprises a water tank body, a water outlet pipe 201 is arranged at the bottom of the water tank body, and two water sealing plates 301 which can be opened and closed are hingedly connected to the inner bottom of the water tank body; a water outlet control mechanism is arranged at the inner bottom of the water tank body, and the water outlet control mechanism comprises a barrel cover 401 connected to the water tank body, a limiting mechanism and an adjusting mechanism both arranged in the barrel cover 401, a plurality of through holes 501 are arranged on the side wall of the barrel cover 401, and an inlet of the water outlet pipe 201 is located in the barrel cover 401; the limiting mechanism makes the two water sealing plates 301 always in a closed state to block the water outlet pipe 201; and the adjusting mechanism is used to control the opening and closing degree of the two water sealing plates 301. When the two water sealing plates 301 are opened, the plurality of through holes 501 facilitate the water in the water tank body to flow into the water outlet pipe 201.

[0025] In some implementations of the present embodiment, a horizontal plate 601 is provided in the barrel cover 401, and the limiting mechanism includes two vertical rods 402 and two springs 403, and the two vertical rods 402 are respectively connected to the two water sealing plates 301; two arc grooves 404 are provided on the horizontal plate 601, and one end of any vertical rod 402 away from the water sealing plate 301 passes through the corresponding arc groove 404, and when the two water sealing plates 301 rotate, the two vertical rods 402 can be driven to move in the two arc grooves 404 respectively; the two springs 403 are respectively located in the two arc grooves 404, one end of any spring 403 is connected to one end of the arc groove 404, and the other end is connected to the vertical rod 402 located in the current arc groove 404; the two vertical rods 402 approach each other during the closing process of the two water sealing plates 301; when the two water sealing plates 301 are fully closed, the two springs 403 are in a compressed state.

[0026] Specifically, the adjustment mechanism includes a control rod 405 rotatably connected to the barrel cover 401, a telescopic mechanism and a tapered shaft 406 that are transmission-connected to the control rod 405. The telescopic mechanism is arranged on the horizontal plate 601. The large diameter end of the tapered shaft 406 is connected to the execution end of the telescopic mechanism, and the small diameter end of the tapered shaft 406 can be inserted between the two vertical rods 402. The control rod 405 controls the telescopic amount of the telescopic mechanism to make the tapered shaft 406 extend between the two vertical rods 402 to control the relative distance between the two vertical rods 402. When the tapered shaft 406 moves between the two vertical rods 402, the distance between the two vertical rods 402 is controlled by the change of the taper, thereby achieving the purpose of controlling the opening and closing degree of the two water sealing plates 301.

[0027] Specifically, the telescopic mechanism includes a frame 407 arranged on the horizontal plate 601, a sleeve 408 inserted through the frame 407 and a screw 409 rotatably connected to the frame 407, the sleeve 408 is threadedly connected to the screw 409; one end of the sleeve 408 away from the screw 409 is connected to the large diameter end of the tapered shaft 406; one end of the screw 409 away from the sleeve 408 is transmission-connected to the control rod 405, and the control rod 405 is used to control the rotation of the screw 409.

[0028] In some implementations of this embodiment, the frame 407 is a U-shaped structure, and the frame 407 includes an integrally formed first vertical plate (not marked in the figure), a transverse support plate (not marked in the figure) and a second vertical plate (not marked in the figure), the first vertical plate and the second vertical plate are respectively arranged at both ends of the transverse support plate, and the first vertical plate and the second vertical plate are both connected to the transverse plate 601; the sleeve 408 is passed through the first vertical plate; the screw 409 is passed through the second vertical plate and is rotatably connected to the second vertical plate; the connection between the screw 409 and the sleeve 408 is located between the first vertical plate and the second vertical plate.

[0029] from Figure 2 From the perspective of the embodiment, the sleeve 408 is provided with a limit plate 4010, which is located between the first vertical plate and the second vertical plate; when the limit plate 4010 abuts against the first vertical plate, the opening of the two water sealing plates 301 reaches the maximum. This design can prevent the two vertical rods 402 from "going over" the large diameter end of the tapered shaft 406. If the two vertical rods 402 "go over" the large diameter end of the tapered shaft 406, the two vertical rods 402 will abut against the sleeve 408 under the action of the elastic force of the two springs 403, so that when the tapered shaft 406 moves to the right, it cannot move, and the water output control mechanism cannot control the opening and closing of the two water sealing plates 301.

[0030] from Figure 4 From the perspective of , a avoidance portion 701 is provided at the hinge of any water sealing plate 301 and the water tank body. In this embodiment, both water sealing plates 301 are semicircular structures, and a avoidance portion 701 (a missing corner design here) is designed at the hinge of the water sealing plate 301 and the water tank body. When the two water sealing plates 301 move away from each other, the left water sealing plate 301 rotates counterclockwise around the hinge point between it and the water tank body, and the right water sealing plate 301 rotates clockwise around the hinge point between it and the water tank body. The existence of the avoidance portion 701 can prevent one water sealing plate 301 from affecting the rotation of the other water sealing plate 301.

[0031] In order to facilitate the control rod 405 to control the rotation of the screw rod 409, a first bevel gear 801 is installed at one end of the control rod 405 located in the barrel cover 401, and a second bevel gear 901 is installed at one end of the screw rod 409 away from the sleeve 408. The second bevel gear 901 meshes with the first bevel gear 801.

[0032] Working principle:

[0033] like Figure 2As shown, when it is not necessary to inject the water in the water tank body into other tanks through the water outlet pipe 201, the small diameter end of the tapered shaft 406 is not located between the two vertical rods 402. At this time, the two vertical rods 402 approach each other under the action of the two springs 403 until the two water sealing plates 301 abut against each other to block the water inlet of the water outlet pipe 201. The two water sealing plates 301 are always in abutment under the action of the two springs 403.

[0034] When it is necessary to inject the water in the water tank body into other boxes through the water outlet pipe 201, the staff rotates the control rod 405 to control the first bevel gear 801 to rotate, the screw 409 rotates under the action of the bevel gear mechanism, and the sleeve 408 moves to the left under the action of the threaded connection, and the tapered shaft 406 moves to the left synchronously under the "push" of the sleeve 408. In the process of moving to the left, the tapered shaft 406 gradually extends between the two vertical rods 402 and abuts against the sides of the two vertical rods 402. In the process of gradually moving to the left between the two vertical rods 402, the taper of the tapered shaft 406 between the two vertical rods 402 will change, and this taper change can gradually increase the distance between the two vertical rods 402, so that the two water sealing plates 301 are gradually opened, and the water in the water tank body can flow into the water outlet pipe 201 through a plurality of through holes 501 to flow to other boxes. When the limiting plate 4010 abuts against the first vertical plate, the two vertical rods 402 contact the large diameter end of the tapered shaft 406 , and at this time, the opening of the two water sealing plates 301 reaches the maximum.

[0035] When the water discharge is completed, the reverse rotation control rod 405 controls the screw rod 409 to reverse through the bevel gear mechanism, and the sleeve 408 moves rightward under the action of the threaded connection, and the tapered shaft 406 moves rightward synchronously under the "pull" of the sleeve 408. During the rightward movement of the tapered shaft 406, the distance between the two vertical rods 402 gradually decreases, and the two water sealing plates 301 gradually approach under the drive of the two vertical rods 402. When the tapered shaft 406 is completely moved out from between the two vertical rods 402, the two water sealing plates 301 are closed, and the water discharge is completed.

[0036] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field.
