Description

Technical Field

[0001] The present invention relates to the technical field of water pumps, and in particular to a siphon pump structure and a siphon drainage system. Background Art

[0002] A siphon pump is a pump that uses the siphon principle to move liquids without the need for traditional mechanical pumps or power sources. It creates a pressure difference in the liquid to move the liquid from a high position to a low position, and is often used for drainage and liquid transportation. The siphon pump system mainly relies on the pressure difference between the inside and outside of the pipe and the flow generated by the deadweight of the liquid, and is suitable for use in scenes with height differences.

[0003] Before the siphon pump starts running, it is necessary to form a pressure difference in the siphon pipeline, that is, the air in the siphon pipeline needs to be pumped out to form a negative pressure in order to suck the liquid into the siphon pipeline. Therefore, a negative pressure pump needs to be arranged in the siphon pump. The negative pressure pump in the siphon pump in the prior art is easily soaked by the pumped up liquid after pumping out the negative pressure. Long-term soaking can easily cause damage to the negative pressure pump, affecting the negative pressure pumping effect of the negative pressure pump, thereby shortening the service life of the siphon pump. Summary of the invention

[0004] The main purpose of the present invention is to provide a siphon pump structure and a siphon drainage system, aiming to solve the problem that the negative pressure pump in the siphon pump in the prior art is easily damaged and the siphon pump has a short service life.

[0005] To achieve the above object, the siphon pump structure proposed in the present invention comprises:

[0006] A siphon, wherein the water inlet end of the siphon is arranged in the area to be drained;

[0007] A water storage structure, the water storage structure comprises a water storage tank and a negative pressure pump, the inner cavity of the water storage tank is divided by a partition to form a first chamber and a second chamber, and the bottom of the partition forms a gap with the bottom wall of the water storage tank, the gap communicates the first chamber and the second chamber, the second chamber is connected to the water outlet end of the siphon pipe, and a first water valve is arranged at the water outlet end of the siphon pipe, the water outlet end of the siphon pipe is higher than the water inlet end of the siphon pipe, and the negative pressure pump is arranged at the top of the first chamber and communicated with the first chamber to pump negative pressure into the first chamber;

[0008] A drain pipe, wherein the water inlet end of the drain pipe is connected to the position of the siphon pipe near its water outlet end, and a second water valve is provided on the drain pipe, and the water outlet end of the drain pipe is connected to the outside;

[0009] The water storage structure also includes a positive pressure pump, which is arranged on the top of the first chamber and communicated with the first chamber to provide positive pressure to the second chamber and discharge the water in the water storage tank from the water inlet end of the siphon tube or the water outlet end of the drain pipe.

[0010] In one embodiment, a third water valve is further provided on the siphon tube, and the third water valve is arranged at a position of the siphon tube away from its water outlet end, so that the water inlet end of the drain pipe is located between the first water valve and the third water valve.

[0011] In one embodiment, a water level sensor is provided near the top of the first chamber, and the water level sensor is used to send a first signal when the water level in the first chamber reaches a preset value. The first signal is configured to adjust the on and off of the first water valve, the second water valve and the third water valve.

[0012] In one embodiment, a liquid sensor is further provided near the water outlet end of the drain pipe, and the liquid sensor is used to detect whether there is liquid flowing in the drain pipe. The liquid sensor is used to send a second signal when it detects that there is no liquid flowing in the drain pipe, and the second signal adjusts the on and off of the first water valve, the second water valve and the third water valve.

[0013] In one embodiment, the siphon pump structure also includes a controller, the first water valve, the second water valve and the third water valve are all solenoid valves, and the first water valve, the second water valve, the third water valve, the water level sensor and the liquid sensor are all electrically connected to the controller.

[0014] In one embodiment, a medicine bin is further provided outside the water storage bin, in which pipe cleaner is stored. The medicine bin is used to inject the pipe cleaner into the water storage bin when the positive pressure pump provides positive pressure to the first chamber.

[0015] In one embodiment, a filter screen is provided at the water inlet end of the siphon tube, and the filter screen is detachably mounted on the siphon tube.

[0016] In one embodiment, the bottom of the second chamber protrudes downward to form a garbage bin, and the bottom of the garbage bin has an openable bin door.

[0017] The present invention further provides a siphon drainage system, which is applied with the above-mentioned siphon pump structure. The siphon drainage system is applied to underground garages, reservoirs, swimming pools or slopes.

[0018] The technical solution of the present invention is to add a water storage structure to the siphon pump structure, and the siphon tube is connected to the second chamber. When in use, the first water valve is opened and the second water valve is closed, and the negative pressure pump at the first chamber pumps negative pressure to the first chamber.

When the water level reaches a certain height, the first water valve can be closed and the second water valve can be opened. The water in the siphon tube is discharged from the drain pipe under the action of gravity, thereby forming a siphon passage and completing drainage.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0029] Before the siphon pump starts running, it is necessary to form a pressure difference in the siphon pipeline, that is, the air in the siphon pipeline needs to be pumped out to form a negative pressure in order to suck the liquid into the siphon pipeline. Therefore, a negative pressure pump needs to be arranged in the siphon pump. The negative pressure pump in the siphon pump in the prior art is easily soaked by the pumped up liquid after pumping out the negative pressure. Long-term soaking can easily cause damage to the negative pressure pump, affecting the negative pressure pumping effect of the negative pressure pump, thereby shortening the service life of the siphon pump.

[0030] In order to solve the above problems, the present invention provides a siphon pump structure 100 .

[0031] See also Figure 1The siphon pump structure 100 of the present embodiment includes a siphon tube 1, a water storage structure 2 and a drainage pipe 3. The water inlet end of the siphon tube 1 is arranged in the area to be drained; the water storage structure 2 includes a water storage tank 21 and a negative pressure pump 22. The inner cavity of the water storage tank 21 is divided by a partition 213 to form a first chamber 211 and a second chamber 212, and a gap is formed between the bottom of the partition 213 and the bottom wall of the water storage tank 21. The gap connects the first chamber 211 and the second chamber 212. The second chamber 212 is connected to the water outlet end of the siphon tube 1, and a first water valve 11 is arranged at the water outlet end of the siphon tube 1. The water outlet end of the siphon tube 1 is higher than At the water inlet end of the siphon tube 1, a negative pressure pump 22 is arranged at the top of the first chamber 211 and is connected to the first chamber 211 to pump negative pressure into the first chamber 211; the water inlet end of the drain pipe 3 is connected to a position of the siphon tube 1 close to its water outlet end, and a second water valve 31 is provided on the drain pipe 3, and the water outlet end of the drain pipe 3 is connected to the external environment; the water storage structure 2 also includes a positive pressure pump 23, which is arranged at the top of the first chamber 211 and is connected to the first chamber 211 to provide positive pressure to the second chamber 212 and discharge the water in the water storage tank 21 from the water inlet end of the siphon tube 1 or the water outlet end of the drain pipe 3.

[0032] The technical solution of the present invention is to add a water storage structure 2 to the siphon pump structure 100, and the siphon tube 1 is connected to the second chamber 212. When in use, the first water valve 11 is opened and the second water valve 31 is closed, and the negative pressure pump 22 at the first chamber 211 pumps negative pressure to the first chamber 211. Since the first chamber 211 and the second chamber 212 are connected, negative pressure is also formed in the second chamber 212, thereby forming a negative pressure in the siphon tube 1 connected to the second chamber 212, and the accumulated water at the water inlet end of the siphon tube 1 is sucked into the siphon tube 1 by the negative pressure and enters the second chamber 212. Since the first chamber 211 and the second chamber 212 are connected, the water level in the first chamber 211 is consistent with the water level in the second chamber 212. When the water level reaches a certain height, the first water valve 11 can be closed and the second water valve 31 can be opened. The water in the siphon tube 1 is discharged from the drain pipe 3 under the action of gravity, thereby forming a siphon passage and completing drainage. The present invention sets a water storage tank 21 and sets a negative pressure pump 22 on the top of the water storage tank 21, so that the negative pressure pump 22 can provide negative pressure for the siphon tube 1 through the second chamber 212, and the water storage tank 21 will temporarily store the water pumped up by the negative pressure, so that the negative pressure pump 22 will not take in water or be soaked by water, thereby avoiding corrosion or damage of the negative pressure pump 22 due to long-term contact with water, extending the service life of the negative pressure pump 22, and thus extending the overall service life of the siphon pump structure 100.

[0033] It is understandable that after long-term use, debris or garbage will accumulate in the siphon tube 1 and the drain pipe 3. If they are not cleaned in time, they will accumulate in the siphon tube 1 or the drain pipe 3 and cause blockage, affecting the use of the siphon pump structure 100. Therefore, a positive pressure pump 23 is provided to squeeze the water in the water storage tank 21 into the drain pipe 3 and the siphon tube 1 to flush the debris or garbage in the drain pipe 3 and the siphon tube 1, so that the debris and garbage are discharged from the water inlet end of the siphon tube 1 or the water outlet end of the drain pipe 3 to ensure the overall smoothness of the siphon pump structure 100.

[0034] It should be noted that the positive pressure pump 23 and the negative pressure pump 22 can be the same pump body, and the functions of pumping negative pressure and providing positive pressure can be achieved by adopting a bidirectional air pump in the prior art.

[0035] Please combine Figure 2 and Figure 3 ,in, Figure 2 This is a schematic diagram of the water levels of the first chamber 211 and the second chamber 212 after the siphon pumping operation is completed. Figure 3 Schematic diagram of the water levels of the first chamber 211 and the second chamber 212 when the water in the water storage tank 21 is discharged by the positive pressure pump 23. Figure 2 and Figure 3 The filled parts of the first chamber 211 and the second chamber 212 represent the water level. During use, after the siphon pumping operation is completed, there is accumulated water in the water storage tank 21. In the initial state, the water level in the first chamber 211 is the same as the water level in the second chamber 212. The positive pressure pump 23 provides positive pressure to the water in the first chamber 211, and the positive pressure pushes the water in the first chamber 211 and raises the water level in the second chamber 212 until the water in the second chamber 212 is squeezed into the siphon 1. The positive pressure is continued to be provided to discharge all the water in the water storage tank 21 from the water inlet end of the siphon 1 or the water outlet end of the drain pipe 3, thereby achieving the cleaning of the siphon 1 and the drain pipe 3. The present invention, through the design of the water storage tank 21, pressurizes the water cached in the water storage tank 21 during the siphon drainage process and squeezes it into the siphon 1 and the drain pipe 3 for cleaning the siphon 1 and the drain pipe 3, without the need to connect an additional water source for cleaning, which saves water and improves efficiency. It should be noted that flushing is not required after every siphon drainage. Whether to perform flushing can be selected based on the usage scenario and the actual conditions of the siphon tube 1 and the drain pipe 3. Moreover, the water storage capacity in the water storage tank 21 is much less than the water capacity in the area to be drained, and during the flushing operation, a container can be set in advance at the water inlet end of the siphon tube 1 to collect garbage and water in the water storage tank 21. Therefore, there is no need to worry that the water squeezed out of the siphon tube 1 will cause water to accumulate in the area to be drained again.

[0036] Furthermore, a third water valve 12 is provided on the siphon tube 1 , and the third water valve 12 is arranged at a position of the siphon tube 1 away from its water outlet end, so that the water inlet end of the drain pipe 3 is located between the first water valve 11 and the third water valve 12 .

[0037] The water inlet end of the drain pipe 3 is located between the first water valve 11 and the third water valve 12, so that the water in the water storage tank 21 can be discharged from the siphon 1 or the drain pipe 3 by the on and off of the third water valve 12 and the second water valve 31. If garbage cleaning is performed, in order to clean the siphon 1 and the drain pipe 3, the first water valve 11, the second water valve 31 and the third water valve 12 need to be opened at the same time, so that the water in the water storage tank 21 can flush the siphon 1 and the drain pipe 3 at the same time, thereby achieving garbage cleaning. However, as mentioned above, not every time the accumulated water in the water storage tank 21 is discharged, it is used to clean the garbage. Therefore, when it is only necessary to empty the water in the water storage tank 21 to avoid the water in the water storage tank 21 being full and damaging the positive pressure pump 23 and the negative pressure pump 22, the third water valve 12 is closed, and the first water valve 11 and the second water valve 31 are opened, so that the water in the water storage tank 21 is discharged from the drain pipe 3, so as to avoid the water in the water storage tank 21 being repeatedly discharged into the area to be drained, causing the area to be drained again to accumulate water.

[0038] In one embodiment, a water level sensor 214 is provided near the top of the first chamber 211. The water level sensor 214 is used to send a first signal when the water level in the first chamber 211 reaches a preset value. The first signal is configured to adjust the on and off of the first water valve 11, the second water valve 31 and the third water valve 12.

[0039] When the water level in the first chamber 211 is too high, water will enter the positive pressure pump 23 and the negative pressure pump 22, causing corrosion damage to the positive pressure pump 23 and the negative pressure pump 22. Therefore, by setting a water level sensor 214, a first signal is sent out when the water level reaches a preset value, the positive pressure pump 23 is controlled to start and the first water valve 11, the second water valve 31 and the third water valve 12 are adjusted according to the first signal to discharge the accumulated water in the water storage tank 21. If it is necessary to flush the siphon 1 and the drain pipe 3 to clean up the garbage at this time, the first water valve 11, the second water valve 31 and the third water valve 12 need to be opened. If only the accumulated water in the water storage tank 21 needs to be discharged, the third water valve 12 is closed, and the first water valve 11 and the second water valve 31 are opened.

[0040] Furthermore, a liquid sensor 32 is provided near the water outlet end of the drain pipe 3. The liquid sensor 32 is used to detect whether there is liquid flowing in the drain pipe 3, and the liquid sensor 32 is used to send a second signal when it detects that there is no liquid flowing in the drain pipe 3. The second signal is configured to adjust the on and off of the first water valve 11, the second water valve 31 and the third water valve 12.

[0041] When the siphon pump structure 100 is draining the area to be drained, water keeps flowing out of the drain pipe 3. When the liquid sensor 32 cannot detect liquid flowing in the drain pipe 3, it means that the water in the area to be drained has been completely drained. At this time, the liquid sensor 32 sends a second signal, controls the positive pressure pump 23 to start according to the second signal, and adjusts the on and off of the first water valve 11, the second water valve 31 and the third water valve 12 to discharge the water in the water storage tank 21. Although the water level in the water storage tank 21 has not reached the preset value at this time, it can avoid the long-term accumulation of water in the water storage tank 21 to cause bacteria breeding and odor generation. If it is necessary to flush the siphon pipe 1 and the drain pipe 3 to clean up garbage at this time, it is necessary to open the first water valve 11, the second water valve 31 and the third water valve 12. If only the accumulated water in the water storage tank 21 is to be discharged, the third water valve 12 is closed, and the first water valve 11 and the second water valve 31 are opened.

[0042] In one embodiment, the siphon pump structure 100 also includes a controller, the first water valve 11, the second water valve 31 and the third water valve 12 are all solenoid valves, and the first water valve 11, the second water valve 31, the third water valve 12, the water level sensor 214 and the liquid sensor 32 are all electrically connected to the controller.

[0043] The controller automatically adjusts the on and off of the first water valve 11, the second water valve 31 and the third water valve 12 according to the first signal and the second signal sent by the water level sensor 214 and the liquid sensor 32, thereby realizing automatic drainage of water in the water storage tank 21, improving the intelligence of the siphon pump structure 100 and improving the drainage efficiency.

[0044] In one embodiment, a medicine bin 24 is further provided outside the water storage bin 21. A pipe cleaner is stored in the medicine bin 24. The medicine bin 24 is used to inject the pipe cleaner into the water storage bin 21 when the positive pressure pump 23 provides positive pressure to the first chamber 211. By adding the pipe cleaner in the medicine bin 24 into the accumulated water in the water storage bin 21 and then flushing and cleaning the drain pipe 3 and the siphon pipe 1, the cleaning efficiency can be significantly improved, and the cleaning effect of the drain pipe 3 and the siphon pipe 1 can be improved.

[0045] In one embodiment, a filter screen 13 is provided at the water inlet end of the siphon 1, and the filter screen 13 is detachably mounted on the siphon 1. The water inlet end of the siphon 1 filters large garbage and debris outside the siphon 1 through the filter screen 13 to prevent them from entering the siphon 1 and causing blockage. At the same time, the filter screen 13 is detachable, which is convenient for removing the filter screen 13 for cleaning or replacement.

[0046] In one embodiment, the bottom of the second chamber 212 protrudes downward to form a garbage bin 25, and the bottom of the garbage bin 25 has an openable bin door 26. It can be understood that the garbage in the accumulated water will also be deposited and accumulated when entering the second chamber 212 through the siphon 1, so a downwardly protruding garbage bin 25 is formed at the bottom of the second chamber 212, so that the garbage can be deposited in the garbage bin 25 without blocking the gap between the partition 213 and the bottom of the water storage bin 21, and an openable bin door 26 is provided at the garbage bin 25, which is convenient for regular cleaning of the garbage in the garbage bin 25.

[0047] The present invention also provides a siphon drainage system, which is applied with the above-mentioned siphon pump structure 100, and the siphon drainage system is applied to underground garages, reservoirs, swimming pools or slopes. The specific structure of the siphon pump structure 100 refers to the above-mentioned embodiment. Since the siphon drainage system adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0048] The above are only optional embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
