Abstract
Description
Technical Field
[0001] This utility model relates to the field of photoelectric water control system technology, and in particular to a photoelectric water control negative pressure siphon component. Background Technology
[0002] The photovoltaic water control system uses a solar photovoltaic booster network to supply water, solving the problem of insufficient pressure in traditional municipal water supply. When agricultural irrigation is not needed, personnel can control water supply remotely via the pipeline network, eliminating the need for on-site monitoring. In existing photovoltaic water control systems, submersible pumps extract water from the bottom of the water. However, when the water level in rivers, lakes, or wells is low or contains sediment or other debris, this sediment tends to accumulate around the pump's drive motor, affecting its normal operation and potentially shortening the pump's lifespan. To address this technical issue, Chinese utility model patent number 2020110725559 discloses a photovoltaic water control negative pressure tornado siphon pump system. This system utilizes a pressure difference to force some water from the outlet pipe into the bottom of a negative pressure tank via a connected backwash pipe. This impacts the sediment at the bottom of the tank, causing it to rise to a certain height. The submersible pump then draws the sediment out along with the water from the bottom of the tank.
[0003] The aforementioned existing technologies require burying part of the structure underground during on-site installation. However, due to limitations imposed by outdoor terrain such as rivers and ponds, the existing technologies are difficult to adapt to the terrain during the layout process, requiring site modifications and greatly increasing the cost of the layout. Furthermore, burying part of the structure in the soil is not conducive to subsequent maintenance by personnel. Utility Model Content
[0004] The purpose of this invention is to solve the problems of difficult installation and subsequent maintenance in the existing technology.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A photoelectric controlled water negative pressure siphon assembly includes a negative pressure tank, a sealing cover on the negative pressure tank, a water outlet on the sealing cover, a water inlet at the bottom of the negative pressure tank, a water suction pipe connected to the water inlet, the water inlet end of the water suction pipe being horizontally aligned with, lower than or higher than the water inlet, a submersible pump inside the negative pressure tank, the submersible pump being electrically connected to an external power source, the water inlet end of the submersible pump being lower than the water inlet, and the water outlet end of the submersible pump being connected to the water outlet.
[0006] Preferably, when the water inlet end of the suction pipe is higher than the water inlet, the water inlet end of the submersible pump is higher than the water inlet.
[0007] Preferably, a bottom valve is provided on the water inlet end of the water suction pipe, and a check valve is provided between the bottom valve and the water inlet end of the water suction pipe.
[0008] Preferably, the sealing cover is provided with a power supply inlet / outlet sealing valve, which is used to supply the power supply line of the submersible pump.
[0009] Preferably, the sealing cover is also provided with an exhaust valve.
[0010] Preferably, the sealing cap is also provided with a liquid replenishment valve.
[0011] The beneficial effects proposed by this utility model are as follows: The negative pressure tank remains sealed throughout operation, maintaining a negative pressure state. The sealing cap further enhances the sealing environment inside the tank by sealing the top. When water is injected into the tank, the submersible pump is powered on and starts, gradually pumping the water from the bottom of the tank from the suction port to the outlet, thus improving the water delivery efficiency. It should be noted that the inlet of the submersible pump must be lower than the suction port to meet the siphon principle's operating conditions. Both the suction port and outlet are located at the bottom of the negative pressure tank. When using the siphon principle for water suction, the actual height of the outlet is lowered below the suction port by the submersible pump's inlet, allowing the tank to maintain a negative pressure state and complete the water suction operation using the siphon principle. When the inlet end of the suction pipe is horizontally aligned with or lower than the suction port, the negative pressure state inside the negative pressure tank allows the suction pipe to use the siphon principle to inject water into the negative pressure tank through the suction port. The horizontal alignment of the inlet end of the suction pipe with the suction port allows the negative pressure tank to be placed on the ground surface, reducing the construction costs associated with deep burial during equipment installation. Furthermore, placing the equipment on the ground surface facilitates regular inspections and maintenance by maintenance personnel, and is beneficial for repairs in case of equipment failure. Conversely, when the inlet end of the suction pipe is horizontally lower than the suction port, the negative pressure tank can be placed at a higher elevation, utilizing the siphon principle to draw water from low-lying areas to higher elevations, enabling the equipment to be adapted to various outdoor terrains.
[0012] Furthermore, during the operation of the submersible pump, a water turbine is generated at the bottom of the negative pressure tank, which is based on the principle of a tornado. This turbine agitates the sediment at the bottom of the negative pressure tank, making it easier for the submersible pump to extract and discharge it. This reduces the risk of excessive sediment buildup at the bottom of the negative pressure tank clogging the water inlet and the water inlet of the submersible pump. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0016] Example 1 Reference Figures 1 to 4A photoelectric controlled water negative pressure siphon assembly includes a negative pressure tank 1, a sealing cover 2 on the negative pressure tank 1, a water outlet 3 on the sealing cover 2, a water intake 4 at the bottom of the negative pressure tank 1, a water intake pipe 5 connected to the water intake 4, the inlet end of the water intake pipe 5 being horizontally aligned with the water intake 4, and a submersible pump 6 inside the negative pressure tank 1, the inlet end of the submersible pump 6 being lower than the water intake 4, and the outlet end of the submersible pump 6 being connected to the water outlet 3. Specifically, the negative pressure tank 1 remains sealed during operation, maintaining a negative pressure state, while the sealing cover 2 seals the top of the negative pressure tank 1, further improving the sealing environment inside the negative pressure tank 1. When water is injected into the negative pressure tank 1, the submersible pump 6 is powered on and started. The submersible pump 6 is used to transport the water gradually injected into the bottom of the negative pressure tank 1 from the water inlet 4 to the water outlet 3, gradually discharging the water to the outside of the negative pressure tank 1, thereby improving the water delivery efficiency inside the negative pressure tank 1. It should be noted that the water inlet of the submersible pump 6 needs to be lower than the water inlet 4 to meet the working conditions of the siphon principle. The water inlet 4 is located at the bottom of the negative pressure tank 1, and the water outlet 3 is also located at the bottom of the negative pressure tank 1. When using the siphon principle for water suction, the actual height of the water outlet 3 is lowered to below the water inlet 4 through the water inlet of the submersible pump 6, allowing the negative pressure tank 1 to maintain a negative pressure state and complete the water suction operation using the siphon principle. When the inlet end of the suction pipe 5 is horizontally aligned with the suction port 4, the negative pressure state inside the negative pressure tank 1 allows the suction pipe 5 to inject water into the negative pressure tank 1 through the suction port 4 using the siphon principle. The arrangement of the inlet end of the suction pipe 5 being horizontally aligned with the suction port 4 allows the negative pressure tank 1 to be placed on the ground surface, reducing the construction cost of deep burial required for equipment installation. At the same time, placing the equipment on the ground surface also helps maintenance personnel to regularly inspect and maintain the equipment, which is beneficial for repairs when the equipment fails.
[0017] Furthermore, during the operation of the submersible pump 6, a water turbine is generated at the bottom of the negative pressure tank 1, which is based on the principle of a tornado. This turbine agitates the sediment at the bottom of the negative pressure tank 1, making it easier for the sediment to be pumped out by the submersible pump 6. This reduces the risk of excessive sediment buildup at the bottom of the negative pressure tank 1, which could clog the water inlet 4 and the water inlet of the submersible pump 6.
[0018] Specifically, a bottom valve 7 is provided on the inlet end of the water suction pipe 5, and a check valve 8 is provided between the bottom valve 7 and the inlet end of the water suction pipe 5. The bottom valve 7 is used to introduce an external water source. After the water source enters the water suction pipe 5 through the bottom valve 7, it will pass through the check valve 8. The check valve 8 is used to prevent the water source from flowing back and being discharged from the water suction pipe 5, thereby ensuring the negative pressure state in the negative pressure tank 1 and improving the stability of the negative pressure state in the negative pressure tank 1 during water injection operations.
[0019] Specifically, the sealing cover 2 is equipped with a power inlet / outlet sealing valve 9, which is used to allow the power cord of the submersible pump 6 to enter. When the submersible pump 6 operates inside the negative pressure tank 1, the negative pressure tank 1 is sealed and filled with water. Therefore, when the power cord of the submersible pump 6 is connected to an external power source, the power cord of the submersible pump 6 extends to the outside of the negative pressure tank 1 through the power inlet / outlet sealing valve 9, thus maintaining the airtightness of the inside of the negative pressure tank 1 while allowing the submersible pump 6 to be connected to an external power source via the power cord.
[0020] Furthermore, depending on different operating conditions, the power supply inlet / outlet sealing valve 9 can be replaced with a sealing ring. The power supply inlet / outlet sealing valve 9 is suitable for sealing under higher pressure conditions, while the sealing ring is suitable for sealing under general lower pressure conditions. The use of the sealing ring helps to reduce the space occupied on the sealing cover 2 and also facilitates the installation and fixing of the power cord.
[0021] Specifically, the sealing cover 2 is also equipped with an exhaust valve 10. To reduce the amount of air outside the negative pressure tank 1, the exhaust valve 10 is used to force air into the negative pressure tank 1. The exhaust valve 10 is a one-way exhaust valve, allowing only the gas inside the negative pressure tank 1 to be discharged outwards. When the gas entering the negative pressure tank 1 with the water source accumulates to a certain level at the top of the chamber of the negative pressure tank 1, it is automatically discharged from the negative pressure tank 1 through the exhaust valve 10. This reduces the risk of accumulated gas in the negative pressure tank 1 affecting the normal operation of the water suction operation. Thus, the exhaust valve 10 achieves pressure reduction inside the negative pressure tank 1.
[0022] Specifically, the sealing cap 2 is also equipped with a liquid replenishment valve 11. The liquid replenishment valve 11 is used to replenish a portion of the liquid in the negative pressure tank 1 before starting. By injecting liquid into the negative pressure tank 1 through the liquid replenishment valve 11, the liquid occupies a portion of the volume in the negative pressure tank 1, thereby reducing the volume occupied by the air pressure until the air pressure in the negative pressure tank 1 is lower than the external atmospheric pressure, forming a negative pressure state. This technical means can improve the efficiency of forming a negative pressure state in the negative pressure tank 1, increase the start-up speed of the negative pressure tank 1, and improve the efficiency of water suction operation.
[0023] Example 2 Reference Figure 5 A photoelectric controlled water negative pressure siphon assembly includes a negative pressure tank 1, a sealing cover 2, a water outlet 3 on the sealing cover 2, a water inlet 4 at the bottom of the negative pressure tank 1, and a water suction pipe 5 connected to the water inlet 4. The inlet end of the water suction pipe 5 is horizontally lower than the water inlet 4. A submersible pump 6 is installed inside the negative pressure tank 1 and is electrically connected to an external power source. The inlet end of the submersible pump 6 is lower than the water inlet 4, and the outlet end of the submersible pump 6 is connected to the water outlet 3. Specifically, when the inlet end of the water suction pipe 5 is lower than the height of the water inlet 4, this arrangement allows the negative pressure tank 1 to be positioned at a higher elevation compared to Embodiment 1, while the water inlet 4 can perform water suction operations from a relatively low-lying area. This enables water to be drawn from low-lying areas to higher elevations.
[0024] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the protection scope of this utility model. Example 3 Reference Figure 6 A photoelectric controlled water negative pressure siphon assembly includes a negative pressure tank 1, a sealing cover 2 on the negative pressure tank 1, a water outlet 3 on the sealing cover 2, a water inlet 4 at the bottom of the negative pressure tank 1, a water suction pipe 5 connected to the water inlet 4, the inlet end of the water suction pipe 5 being horizontally higher than the water inlet 4, a submersible pump 6 inside the negative pressure tank 1, the submersible pump 6 being electrically connected to an external power source, the inlet end of the submersible pump 6 being lower than the water inlet 4, and the outlet end of the submersible pump 6 being connected to the water outlet 3. When the inlet end of the water suction pipe 5 is higher than the water inlet 4, this arrangement allows the negative pressure tank 1 to be positioned below ground level compared to embodiments one or two, enabling the water inlet 4 to draw water from a higher water source.
[0025] Example 4 Reference Figure 7 Specifically, when the inlet end of the suction pipe 5 is higher than the suction port 4, the inlet end of the submersible pump 6 is also higher than the suction port 4. Under the action of the siphon principle, water from a higher water source is drawn into the suction port 4 by the suction pipe 5 and injected into the negative pressure tank 1. The submersible pump 6 assists in accelerating the extraction of water from the negative pressure tank 1. Through the above, when the inlet end of the suction pipe 5 is horizontally higher than the suction port 4, and the inlet end of the submersible pump 6 is also higher than the suction port 4, the negative pressure tank 1 can perform water extraction from a higher water source through the siphon principle.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
