Description

Technical Field

[0001] The utility model relates to the technical field of automatic water discharge equipment, in particular to an automatic water discharger. Background Art

[0002] Each group of boreholes will be connected to a drainage manifold. In order to prevent the accumulated water in the boreholes from gathering in the manifold and clogging the pipeline, a drain will be installed at the end of the manifold to drain the accumulated water. In the past, most drains were manual drains, which drained water by manually controlling the drain valve. However, manual drains are overly dependent on drain workers and have great limitations. Hidden dangers such as untimely draining of water, valves not tightly closed, and rapid filling of the well after draining water frequently occur underground, seriously threatening the stability of the extraction system. Impurities on the inner wall of the automatic drain will gradually accumulate, causing blockage of the pipeline or valve, which will affect the normal operation of the drain and even cause the drain to fail to drain water smoothly, thus affecting the operation of the entire water supply system. Utility Model Content

[0003] The utility model aims to provide an automatic water drainer to solve the problem of draining water by manually controlling the valve of the water drainer. However, the manual water drainer is overly dependent on the drainer and has great limitations. Problems such as untimely draining, loose valve closure, and rapid filling of the water tank after draining frequently occur underground, and the inside of the water tank cannot be cleaned in time, resulting in blockage of pipes and valves.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic water discharger, installed on a water tank, including a water inlet, a gas extraction branch pipe, a float, a cleaning device, a baffle and a water outlet. A water inlet is provided at the top end of the left end of the water tank, and a water outlet is provided at the bottom end of the right end. The other end of the water inlet is connected to the flange of the manifold. A balancing valve is provided at the top of the water tank. The balancing valve is connected to the gas extraction branch pipe connected to the manifold through a negative pressure balancing pipe, and the other end is connected to the water tank. Gas distribution valves are provided on the left and right sides of the balancing valve, respectively. One end of the gas distribution valve is connected to the water tank, and the other end is connected to the atmospheric air.

[0005] A filter plate is arranged at the bottom end of the water tank, and the bottom of the water tank is arranged as a sedimentation space. A sewage outlet is provided at the bottom end of the front side of the sedimentation space. A vertical first slide bar is arranged on the filter plate, and a float is slidably matched on the first slide bar. A cleaning device is fixedly connected to the upper and lower ends of the float. A second slide bar is arranged at the top end of the first slide bar, and the second slide bar contacts the top of the water tank. A baffle is slidably matched on the second slide bar.

[0006] The cleaning device includes a rotating shaft, a connecting plate and a cleaning plate. The connecting plate is evenly installed at an angle on the outside of the rotating shaft for use with the water flow flowing into the water inlet. The top of the connecting plate is fixedly connected to the cleaning plate, and a number of brushes are arranged on the cleaning plate, which are in conflict with the inner wall of the water tank.

[0007] Preferably, the top end of the first sliding rod is arranged corresponding to the top end of the water inlet, the diameter of the second sliding rod is smaller than that of the first sliding rod, and through holes are provided on the first sliding rod and the second sliding rod.

[0008] Preferably, a touch block is connected to the bottom end of the gas distribution valve, and the other end of the touch block is connected to an extrusion valve switch of the gas distribution valve. A return spring is connected to the extrusion valve switch for use in conjunction with the baffle.

[0009] Preferably, a balancing valve linkage device is also included, which is arranged on the baffle, and a threaded rod is arranged on the baffle, a turntable is meshed on the threaded rod, and a linkage rod is eccentrically arranged on the turntable and connected to the valve of the balancing valve.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The water tank of the automatic water discharger is connected to the gas pipeline, the balancing valve and the water inlet are opened, the gas distribution valve is closed, and the water outlet is closed under the action of negative pressure. At this time, the water in the manifold flows into the water tank of the water discharger through the water inlet pipe, and the float continues to rise as the water accumulates. When the amount of water accumulates to a certain amount, the large float pushes the upper baffle upward to open the gas distribution valve, close the balancing valve, and the water tank is connected to the atmosphere. The water inlet is closed under the action of negative pressure. Under the influence of gravity, the water outlet is opened to discharge water. As the accumulated water is discharged, the float drops, and the upper baffle is pulled down at the bottom of the slide bar to close the gas distribution valve, open the balancing valve, isolate the water tank from the atmosphere, and connect to the extraction pipe, and the float returns to the initial position. Under the influence of negative pressure, the water outlet is closed, the water inlet is opened, and water is stored again. This cycle is repeated to achieve automatic water discharge. At the same time, when the float slides up and down due to the buoyancy of the water flow, it drives the cleaning device to move up and down. The connecting plate of the cleaning device is set at an angle and rotates due to the impact force of the water flow falling from the water inlet, so as to clean the inner wall of the water tank. At the same time, the impurities on the cleaned inner wall of the water tank are settled to the sedimentation space at the bottom and discharged through the sewage outlet, ensuring that the internal device can avoid unstable operation caused by excessive impurities. At the same time, a large observation window is adopted for convenient observation and easy fault finding. The water tank is outside the gas pipeline, with a more reasonable layout and easy use. The cleaning device is linked with the water flow, does not require electric drive, and has a simple structure and is easy to maintain. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments 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 in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1: Please refer to Figure 1 , 24. An embodiment of the utility model: an automatic water discharger is installed on a water tank 1, including a water inlet 2, the water inlet 2 is the entrance of the water storage in the water tank 1, used to introduce water flow, a gas extraction branch pipe 3, a float 6, a cleaning device 7, a baffle 8 and a water outlet 9. The water inlet 2 is provided at the top of the left end of the water tank 1, and the water outlet 9 is provided at the bottom of the right end. The water outlet 9 is the outlet of the water tank 1, used to discharge the stored water flow, and the water flow is discharged regularly through the negative pressure. The other end of the water inlet 2 is connected to the flange of the manifold. A balancing valve 5 is provided at the top of the water tank 1, and the balancing valve 5 is passed through the balancing valve 5. The negative pressure balance pipe is connected to the gas extraction branch pipe 3 connected to the manifold, which is used to maintain the pressure balance inside the water tank 1 to prevent problems caused by negative pressure or positive pressure during the water flow in the water tank 1. The balance valve 5 is connected to the gas extraction branch pipe 3 connected to the manifold through the negative pressure balance pipe, and the other end is connected to the water tank 1. The left and right sides of the balance valve 5 are respectively provided with gas distribution valves 4. The gas distribution valve 4 controls the gas channel between the inside of the water tank 1 and the external environment to ensure that it can be connected to the atmosphere when needed. One end of the gas distribution valve 4 is connected to the water tank 1, and the other end is connected to the atmospheric air.

[0026] A filter plate is arranged at the bottom end of the water tank 1, and the bottom of the water tank 1 is arranged as a sedimentation space. The sedimentation space precipitates the impurities cleaned by the cleaning device 7, and the sewage outlet 10 is opened and closed by the solenoid valve to discharge. A sewage outlet 10 is opened at the bottom end of the front side of the sedimentation space, and a vertical first slide bar is arranged on the filter plate. A float 6 is slidably matched on the first slide bar. The float 6 is used to detect the water level. When the water level rises, the float 6 rises accordingly, and at the same time, the baffle 8 is lifted up, so that the air distribution valve 4 and the balancing valve 5 are linked to open or close, so as to store water and discharge water. The cleaning device 7 is fixedly connected to the upper and lower ends of the float 6. A second slide bar is arranged on the top of the first slide bar, and the second slide bar is in conflict with the top of the water tank 1. The baffle 8 is slidably matched on the second slide bar. When the water level rises, the float 6 rises due to buoyancy, so that the baffle 8 is lifted up or dropped, and is linked with the air distribution valve 4 and the balancing valve 5 to store water or discharge water from the device.

[0027] The top of the first slide bar is arranged corresponding to the top of the water inlet 2, the diameter of the second slide bar is smaller than that of the first slide bar, and through holes are provided on the first slide bar and the second slide bar.

[0028] A touch block is connected to the bottom end of the gas distribution valve 4, and the other end of the touch block is connected to the extrusion valve switch of the gas distribution valve 4. A reset spring is connected to the extrusion valve switch for use with the baffle 8. When the baffle 8 rises, the baffle 8 squeezes the touch block, and the touch block squeezes the extrusion valve switch of the gas distribution valve 4, thereby opening the gas distribution valve 4. When the baffle 8 descends, the reset spring provides a force to reset the extrusion valve switch, thereby closing the gas distribution valve 4, thereby realizing linkage with the baffle 8.

[0029] It also includes a linkage device for the balancing valve 5, which is arranged on the baffle 8. A threaded rod 801 is arranged on the baffle 8. A turntable 802 is meshed on the threaded rod 801. A linkage rod is eccentrically arranged on the turntable 802 and connected to the valve of the balancing valve 5. When the baffle 8 rises, the threaded rod 801 is driven to rise, and at the same time, the threaded rod 801 drives the turntable 802 to rotate. When the turntable 802 rotates on the threaded rod 801, the eccentrically arranged linkage rod is driven to rotate and slide in the hole groove set on the turntable 802, and the valve of the balancing valve 5 is closed at the same time. When the water level drops and the baffle 8 is reset, the threaded rod 801 is driven to drop, and the turntable 802 rotates on the threaded rod 801, so that the valve of the balancing valve 5 is opened, thereby performing linkage.

[0030] The sewage outlet 10 is provided with a solenoid valve for opening or closing the sewage outlet 10, and also includes a filter screen for filtering large particles of impurities. The filter screen is used to filter the water flow entering the water tank 1 to prevent impurities from entering the system. It is connected to the water inlet 2 and also includes a transparent resin plate installed on the outer end of the circumference of the water tank 1 for observing the internal structure. The design of the transparent resin plate allows the user to easily observe the internal structure of the water tank 1, so as to facilitate timely detection of problems and maintenance.

[0031] In the water storage stage, the automatic water discharger water tank 1 is connected to the gas pipeline, the balance valve 5 and the water inlet 2 are opened, the gas distribution valve 4 is closed, and the water discharge port is closed under the action of negative pressure. At this time, the water from the manifold flows into the water discharger water tank 1 through the water inlet pipe, and the float 6 continues to rise as the accumulated water increases. When the accumulated water reaches a certain amount, the large float 6 pushes the upper baffle 8 upward, opens the gas distribution valve 4, closes the balance valve 5, and the water tank 1 is connected to the atmosphere. The water inlet 2 is closed under the action of negative pressure, and under the influence of gravity, the water discharge port is opened to discharge water.

[0032] During the water discharge phase, as the accumulated water is discharged, the float 6 descends, and the upper baffle 8 is pulled downward at the bottom of the slide bar, the air distribution valve 4 is closed, the balance valve 5 is opened, the water tank 1 is isolated from the atmosphere, and connected to the extraction pipe, and the float 6 returns to the initial position. Under the influence of negative pressure, the water discharge port is closed, the water inlet 2 is opened, and water is stored again. This cycle is repeated to achieve automatic water discharge.

[0033] Example 2: Please refer to Figure 3 , based on Example 1, it also has the following structure:

[0034] The cleaning device 7 includes a rotating shaft, and the rotating shaft serves as the supporting shaft of the entire cleaning device 7, so that the connecting plate 701 and the cleaning plate 702 can rotate around it. The connecting plate 701 and the cleaning plate 702 are evenly installed at an angle on the outside of the rotating shaft. The connecting plate 701 is evenly installed at an angle with the rotating shaft, and is used to cooperate with the falling water flow when the water inlet 2 is storing water. The water flow provides an impact force, and at the same time, the connecting plate 701 set at an angle is rotated by the impact of the water flow, thereby driving the cleaning plate 702 to rotate, and the inner wall of the water tank 1 is cleaned. At the same time, the connecting plate 701 is made of polyethylene material, which can better utilize the buoyancy of the water flow and is easier to rotate. When the water flow is discharged, the cleaning device 701 set at the bottom of the float 6 The device 7 is rotated by the fluidity discharged by the water flow, so as to clean the inner wall, ensure the cleanliness of the interior, and avoid the deterioration of the operation effect of the device due to excessive impurities. It is used in conjunction with the water flow flowing into the water inlet 2. A cleaning plate 702 is fixedly connected to the top of the connecting plate 701. A number of brushes are arranged on the cleaning plate 702. The brushes are in conflict with the inner wall of the water tank 1. A number of reinforcing ribs are evenly arranged at the bottom end of the filter plate. The reinforcing ribs are located at the bottom end of the filter plate to reinforce the filter plate structure and increase its stability and durability. A vertical support rod is arranged at the intersection of the reinforcing ribs corresponding to the first slide bar. The other end of the support rod is connected to the water tank 1 and is arranged at the intersection of the reinforcing ribs, connected to the first slide bar, and connected to the water tank 1 to support the filter plate.
