Description

[Technical field]

[0001] The invention relates to the technical field of pumping stations, in particular to a novel deep well pumping station for water supply and irrigation. [Background Technology]

[0002] At present, the main water supply methods for irrigation water in the market are water supply pump rooms and water supply units. The underground type only places the pump unit in the FRP cylinder, and then realizes the irrigation function through the form of a dry pump station. Specifically, the variable frequency water supply pump unit is built into a special FRP cylinder, and the natural water is supplied through the front pipeline, and then the variable frequency dry pump unit is pressurized to supply water at the back end. Theoretically, no water will appear inside the cylinder during operation, and the entire pressurization process is carried out in the pipeline. At the same time, a small submersible sewage pump is placed at the lowest point inside the cylinder to prevent internal water accumulation and short circuit failure in the event of a fault. However, the disadvantages of this solution are mainly reflected in:

[0003] (1) This pump station is an optimization of the traditional ground water supply pump group. However, considering that the operation of the dry pump group generates a lot of heat and can only be dissipated by air cooling, once the pump station is buried, the heat is difficult to exchange, which can easily lead to excessive internal temperature and equipment damage;

[0004] (2) At the same time, if there is a pipeline failure or a pressure tank failure, it may cause leakage. Once the leakage is too large, the small submersible sewage pump will not be able to pump water in time, resulting in the equipment being completely submerged and damaged. Therefore, in terms of risk, the risk of dry pumping stations is much higher than that of wet pumping stations.

[0005] (3) The installation of dry pump units is done by hard bolt connection, so in terms of later maintenance costs and maintenance safety, the cost and risk are higher than those of wet pump stations. [Summary of the invention]

[Specific implementation method]

[0026] The present invention is further described below in conjunction with the accompanying drawings:

[0027] As attached Figure 1 To Attachment Figure 7 As shown, the present invention provides a new type of deep well pump station, which has three main parts: a deep well pump water supply system, a submersible sewage pump drainage system, and a glass fiber reinforced plastic cylinder water storage system.

[0029] In the FRP cylinder water storage system, the cylinder is made of FRP, which is wound with glass fiber and resin, and can achieve the following functions:

[0030] (1) Water is introduced from the lake bottom or rainwater collection pool into the pump station through the water inlet pipe;

[0031] (2) The volume of water storage is controlled by the electric float valve of the water inlet pipe. When the set volume is reached, the electric float valve will close to prevent the internal water level from being too high. When the water level is not enough, the electric float valve will automatically open to ensure the internal water storage volume;

[0032] (3) Use the liquid level meter and the electric control cabinet to determine the minimum pump stop level and the submersible sewage pump start level to ensure that the water pump will not be damaged due to insufficient heat dissipation;

A pressure tank 19 for ensuring the stability of water supply is installed at the connection between the deep well pump outlet pipe 14 and the deep well pump gate valve 18. A deep well pump outlet pipe flexible joint 13 is installed at the other end of the deep well pump outlet pipe 14; the deep well pump 8 It is placed in the deep well pump shaft 4, which is a vertically arranged cylinder. The deep well pump shaft 4 is fixed on the inner bottom surface of the pump station cylinder 29 and extends from the inner bottom surface of the pump station cylinder 29 to above the highest water storage level. A number of through holes 32 arranged in an array are provided on the side wall of the deep well pump shaft 4. The deep well pump 8 draws water from the middle part of the deep well pump shaft 4 through the water suction port 31; a bottom limiting device 33 and a side limiting device 34 are provided inside the deep well pump shaft 4, and the bottom limiting device 33 and the side limiting device 34 are both fixed on the inner wall of the deep well pump shaft 4. The bottom limiting device 33 is located below the deep well pump 8 and is used to support the motor of the deep well pump 8. The side limiting device 34 is located outside the deep well pump 8 and is used to prevent the deep well pump 8 from vibrating during operation.

[0036] In the deep well pump water supply system, the deep well pump is placed downward through the wellbore of the deep well pump. Two limit devices are arranged inside the wellbore. The bottom limit is used to support the motor of the deep well pump, and the side support is used to prevent vibration during the operation of the water pump. At the same time, holes are drilled on the wellbore of the deep well pump to ensure the flow state of the water pump. The deep well pump draws water from the middle of the cylinder through the water suction port, and then pressurizes the water supply through the pressure pipe. It is connected through the top hose and the fixed valve to facilitate later disassembly and maintenance, and an air pressure tank is installed at the place where the collection pipe is to ensure the stability of the water supply. The entire deep well pump water supply system is a constant pressure water supply system, and it can decide whether to supply water according to the pressure at the back end.

[0037] The submersible sewage pump drainage system comprises a submersible sewage pump 1, which is arranged at the bottom of the pump station cylinder 29, the water outlet end of the submersible sewage pump 1 is connected to the pressure pipe 7, the other end of the pressure pipe 7 extends to above the highest water storage level and is connected to the sewage pump outlet pipe 27, a sewage pump check valve 24, a sewage pump flexible joint 25 and a sewage pump butterfly valve 26 are sequentially installed between the pressure pipe 7 and the sewage pump outlet pipe 27, a sewage pump outlet pipe flexible joint 28 is installed at the other end of the sewage pump outlet pipe 27, the submersible sewage pump 1, the liquid level meter 5, the electric float valve 10, and the deep well pump 8 are electrically connected to the intelligent electric control cabinet 20 respectively; the submersible sewage pump 1 is installed on the autocoupler base 2, and the autocoupler base 2 is fixed to the bottom of the pump station cylinder 29; the submersible sewage pump drainage system also comprises a water pump guide rail 3, the water pump guide rail 3 is vertically arranged, one end of the water pump guide rail 3 is installed on the autocoupler base 2, and the other end of the water pump guide rail 3 extends to the highest water storage level.

[0038] In the sewage discharge system of the submersible sewage pump, its functions are mainly divided into three aspects:

[0039] (1) When the internal water level exceeds the set maximum water storage level, the submersible sewage pump will automatically start to assist drainage to prevent the water level from being too high to submerge the valve and air pressure tank, leading to possible failure;

[0040] (2) When the water quality is poor, impurities and sludge will be brought in. Since the deep well pump only extracts the middle water, the bottom cannot be cleaned. At this time, the submersible sewage pump can be manually opened to discharge the impurities and sludge at the bottom of the cylinder;

[0041] (3) When the pump station is located in the north, the deep well pump cannot discharge all the water in the cylinder, so a submersible sewage pump can be used for forced discharge to prevent internal damage due to freezing.

[0042] The specific working process of the present invention is as follows: the water inlet pipe 11 is connected to the corresponding water collection pool or lake, and water will begin to accumulate in the cylinder. When the water accumulation easily reaches the required volume, the electric float valve 10 inside the water inlet pipe receives the closing signal and closes to ensure that the internal water level will not be at an excessively high liquid level, thereby affecting the top valve and pressure tank 19. When an external signal is given, such as water shortage or timed irrigation, the internal deep well pump 8 will start to pressurize the internal water for discharge until a stop pump signal is given or the water pump is turned off when the minimum stop pump liquid level is reached; during the entire water supply process, because of the presence of the pressure tank 19 and the frequency converter of the electric control cabinet, the effect of constant pressure water supply can be achieved; the submersible sewage pump 1 is used to discharge the bottom sewage during normal maintenance and for emergency drainage when the liquid level is too high.

[0043] In the present invention, the electric float valve can be replaced with a non-powered buoy valve when the space is relatively large, so that the frequent start and stop of the electric valve can be avoided, and the effect of stopping water inflow when the water reaches a certain liquid level can be better achieved. In addition, the present invention also has the following features: (1) The pump station is equipped with a deep well pump, and the deep well pump is equipped with a mounting cylinder to avoid vibration during operation; (2) The pump station valves and air pressure tanks are placed above the beam to avoid water immersion, while also saving external space; (3) Compared with the common dry pump stations on the market, the cylinder of the present invention serves as a water reservoir, and the heat dissipation problem is guaranteed; (4) The present invention is equipped with a submersible sewage pump for sewage and emergency drainage.

[0044] The present invention is not limited to the above-mentioned embodiments, and any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principles of the present invention shall be equivalent replacement methods and shall be included in the protection scope of the present invention.
