The computer, further the computer-controlled pump 271 of the liquid supply device 14 operates through the input connector 273 to deliver the liquid from the liquid supply source to the liquid storage device 12 through the output connector 275 through the pipe.

The liquid enters the introduction unit 134 through the inlet joint 36 of the liquid storage device 12, and the pressure of the liquid pushes the one-way valve block 139 to move and compress the spring 151, so that the liquid can enter the connecting pipe 135, and further the liquid pushes the valve body 199 through the channel 131 The movable part 213 is moved from the closed position (as shown in Fig. 6) to the non-closed position (as shown in Fig. 9), so that the liquid can enter the first chamber 111, and a small part of the liquid is removed from the column 70. The channel 72 enters the recessed chamber 61, as shown in Fig. 10, in this state, since the main float 94 is located at the low liquid level position, the pressing end 86 of the secondary rocker arm 84 is away from the through hole 74, so that the through hole 74 It is not blocked by the gasket 92, so the liquid in the recessed chamber 61 will overflow into the inner chamber 44 from the through hole 74, and the liquid entering the first chamber 111 will enter the second chamber 113 through the connecting hole 133 ( As shown in Figure 10), since the safety float 195 is located at a non-high liquid level position, the liquid drop plug 221 is separated from the liquid drop port 173 by a distance, and the liquid further located in the second chamber 113 flows through the drop liquid The port 173 enters the groove chamber 155 of the base 153 , and the liquid located in the groove chamber 155 enters the outer container chamber 24 of the outer cylinder 20 along the flow channel 157 .

It is worth mentioning that, because the size of the channel 72 of the column 70 is smaller than the size of the connecting hole 133 and the liquid drop port 173, the flow rate of the liquid entering the outer chamber 24 is higher than that entering the inner chamber 44. The liquid in the valve body will overflow from the through hole 74, causing the liquid pressure generated in the recess 61 to be lower than the liquid pressure in the channel 131 and the first chamber 111, so the movable part 213 of the valve body 199 remains in the non-closed position.

When the liquid enters the outer chamber 24 and the height of the liquid in the outer chamber 24 is not enough to displace the guide float 253 from the non-blocking position to the blocking position, a small amount of the liquid entering the inner chamber 44 will also pass through the gap 56 of the inner cylinder 42 , The opening 50 enters the outer container chamber 24 . When the liquid level of the outer chamber 24 rises to the point where the guide buoy 253 is displaced to the blocking position, the sealing member 255 of the guide buoy 253 tightly abuts against the closing surface 52 of the inner cylinder 42, so that the liquid height of the outer chamber 24 gradually increases. When the liquid level of the outer chamber 24 rises higher than the flow channel 157 of the base 153, the liquid in the outer chamber 24 quickly overflows into the inner chamber 44, which further causes the main float 94 to follow the liquid level of the inner chamber 44. Rapid rise from low level to high level.

Referring to Fig. 12, when the height of the liquid in the inner chamber 44 rises so that the main float 94 is displaced to the high liquid level position, the main rocker arm 76 pivots in conjunction with the secondary rocker arm 84 so that the pressing end 86 is close to the through hole 74, Further, the gasket 92 plugs the through hole 74, so that the liquid entering the cavity 61 cannot escape from the through hole 74, but the liquid can still enter the cavity 61 from the channel 72 of the column 70. When the liquid pressure in the cavity 61 rises When the liquid pressure is greater than the first chamber 111 and the channel 131, the movable portion 213 of the valve body 199 is pushed by the liquid pressure to move from the non-closed position to the closed position, so that the liquid delivered from the liquid supply device 14 cannot enter the first chamber. In other words, the liquid can only reach the channel 131 and cannot continue to flow. The further continuous operation of the pump 271 makes the pressure of the internal pipeline 277 greater than 3.5kg/cm2. The computer of the liquid supply system 14 controls the pump 271 Stop running, as shown in Figure 11, the liquid storage device 12 is in a high (full) liquid level state.

Assuming that the fog machine on the stage is in operation, the pump of the fog machine is connected to the outlet connector 38 of the liquid storage device 12 through the pipeline. With the operation of the fog machine, the liquid level in the outer chamber 24 gradually drops to the point where it cannot support the guide float 253, so that the guide float 253 is displaced from the blocking position to the non-blocking position, as shown in Figure 12, The liquid originally kept in the inner chamber 44 enters the outer chamber 24 through the gap 56 , the opening 50 and the gap between the guide buoy 253 and the inner cylinder 42 , so that the liquid level in the outer chamber 24 increases.

As the liquid in the inner chamber 44 flows to the outer chamber 24 to reduce the height of the liquid, the main float 94 loses its buoyancy support and is displaced from the high liquid level position to the low liquid level position, the main rocker arm 76 is linked by the main float 94 to pivot and The secondary rocker arm 84 is driven to pivot so that the abutting end 86 is far away from the through hole 74 (as shown in Figure 4), further the sealing gasket 92 does not block the through hole 74, and the liquid kept in the recess 61 overflows from the through hole 74, This causes the pressure of the internal pipeline 277 to drop. When the first pressure switch 291 detects that the pressure of the internal pipeline 277 drops below 2.8kg/cm2, the first pressure switch 291 outputs a signal to the computer of the liquid supply device 14, and the liquid supply device The computer-controlled pump 271 of 14 operates again, delivering liquid from the liquid supply source to the liquid storage device 12 until the main float 94 is displaced to the high liquid level position again.

Assuming that even if the main float 94 is in a high liquid level position, the pump 271 of the liquid supply device 14 continues to operate, so that the liquid continues to enter the liquid storage device 12, as shown in FIG. 13, the content chamber 44 and the The liquid height of the outer chamber 24 is gradually increased, so that the safety float 195 is displaced from the non-high liquid level position to the high liquid level position due to the buoyancy of the liquid, and the safety rocker arm 177 is linked to pivot, and further the safety rocker arm 177 is linked to fall. The liquid plug head 221 is displaced to plug the liquid drop port 173. In this state, the through hole 74 is plugged and the liquid drop port 173 is also plugged, so the liquid can only flow to the second chamber 113 and the alcove 61 cannot proceed further, further ensuring that the liquid level does not exceed the height of the top cover 26.

It is worth mentioning that the ventilation element 27 provided on the top cover 26 provides air flow when the liquid enters the liquid storage device 12 or the stage equipment draws the liquid inside the liquid storage device 12, so that the interior of the liquid storage device 12 is maintained at the external atmospheric pressure. The forces are approximately equal, and the liquid can be smoothly operated whether the liquid is transported into the liquid storage device 12 or the liquid is drawn from the liquid storage device 12 .

The present invention controls the secondary rocker arm 84 to open or close the through hole 74 through the main buoy 94 linked with the main rocker arm 76, so that the liquid pressure inside the recess 61 of the liquid level controller 58 changes and controls the movable part 213 of the valve body 199 to move to the closed position Or the open position, which can effectively control whether the liquid can enter the inner chamber 44 and the outer chamber 24.

Through the arrangement of the safety float 195, when the liquid supply device 14 is over-supplied, when the liquid level inside the liquid storage device 12 causes the safety float 195 to move from the non-high liquid level position to the high liquid level position, even if the liquid is supplied. When the pump 271 of the device 14 keeps operating, the liquid level controller 58 can still prevent the liquid from being continuously injected into the inner chamber 44 and the outer chamber 24, so that the liquid level of the liquid storage device 12 will not exceed the top cover 26 and overflow.

Since the liquid storage device 12 is provided with an independent liquid level controller 58, a single liquid supply device 14 is allowed to supply liquid to a plurality of liquid storage devices 12 at the same time, and a plurality of liquid storage devices 12 can individually control the liquid supplied by the liquid supply device 14. Whether the inner chamber 44 and the outer chamber 24 can be entered, so that a single liquid supply device 14 can supply liquid to a plurality of liquid storage devices 12 at the same time, and each liquid storage device 12 can supply the liquid required for the operation of more than one stage equipment.

Through the arrangement of the safety buoy 195, the safety rocker arm 177, the liquid drop plug 221 and the liquid drop port 173, when the liquid level controller 58 has malfunctions caused by foreign objects or aging after long-term use, the liquid level in the outer container chamber 24 will be too high. high, causing the safety float 195 to rise to an excessively high liquid level position, plugging the liquid drop port 173 to prevent the liquid from continuing to enter the outer chamber 24 and the inner chamber 44, which can prevent the oil storage device 12 from overflowing the oil storage device 12 when it fails. , to prevent the droplets from reaching the consumer groups on the scene, once the safety float 195 rises and the droplet plug 221 and the droplet port 173 are sealed and blocked, it means that the oil reservoir 12 is faulty, so it will not open again by itself. It must be dismantled for maintenance, so it can avoid the pollution of the environment and people caused by the failure of the oil reservoir 12.

It is worth mentioning that the design of the liquid drop plug 221 is like a mushroom shape, and the outer circumference is very thin to function like a suction cup. Once the safety float 195 rises to an excessively high liquid level, the liquid drop plug 221 sucks the liquid drop. The liquid port 173, because the liquid drop plug head 221, the through hole 74 and the one-way valve block 139 of the one-way valve body 137 are all blocked, so the entire liquid flow channel is completely closed, so that the first, second and third The interior of the three main bodies 60, 98, and 171 are all filled with water, and a certain water pressure is formed inside. When the water level drops to such an extent that the safety buoy 195 and the main buoy 94 lose their buoyancy support, the safety buoy 195 cannot be opened or dropped. The liquid plug head 221, because only the small through hole 74 is opened at this time, and there is still a certain pressure inside the first, second and third bodies 60, 98, 171 so that the weight of the safety buoy 195 is not enough to resist falling liquid The suction force of the plug head 221, so the liquid drop plug head 221 keeps the liquid drop port 173 closed, and the pressure existing inside the first, second and third bodies 60, 98, 171 also makes it impossible for the inlet joint 36 to connect to the external liquid. Into the liquid level controller 58, even if a very small amount of liquid flows into the through hole 74, it is difficult to continue to store water. In this way, the liquid storage device 12 can be found to be faulty by the relevant personnel under the condition that the liquid does not leak, and further personnel can repair the faulty liquid storage device 12 .

In the present invention, the inner and outer chambers 44 and 24 cooperate with the design of the guide buoy 253, so that the liquid will enter and remain in the content chamber 44 only after the liquid has passed through the flow channel 157, so that the main buoy 94 will not be close to the height. The displacement between the liquid level position (the liquid supply equipment 14 supplies liquid) and the high liquid level position (the liquid supply equipment 14 does not supply liquid) can solve the problem of the pump 271 of the liquid supply equipment 14 being repeatedly started and closed in a short time.

Having described the basic teachings of this invention, many extensions and variations will be apparent to those of ordinary skill in the art. For example, the liquid storage device 12 can not only be matched with the liquid supply device 14 described in the drawings and the description, but the liquid storage device 12 can also be matched with other types of liquid supply devices 14 . Alternatively, the liquid supply system 10 of the present invention is not limited to only be used in fog machines, snow machines and other equipment.
