These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0027] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application.

[0028] The terms "first", "second", "third", "fourth" and the like in the description of this application and in the claims, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the use of these terms herein is to be construed to cover the embodiments of the application described herein, for example, where a particular element appears first, second, third, or fourth, the element appearing subsequently can be construed as being the second, third, fourth or fifth, etc., element.

[0029] In the embodiments of the present application, the words "exemplary" and "for example" are used to mean serving as an example, instance, or illustration, at 5 2 least. Any implementation described herein as "exemplary" or "for example" is not necessarily to be construed as preferred or advantageous over other implementations. The

[0030] In the prior art, the control unit of the water supply pump station system adopts a programmable control unit, such as a PLC control system. The control unit plays a central control role to control the water pump unit. The control unit can also carry a remote control template to realize remote monitoring. The water pump unit of the water supply pump station system can be one or more. Each water pump unit has multiple water pumps. Different water pumps can distribute raw water to different users to achieve the purpose of distributing water supply. Under normal circumstances, the water pumps of the water pump unit in the pump house will alternately run or simultaneously run to meet the water demand of the users.

[0031] Since the control unit needs to be carried by a power distribution cabinet or a control cabinet for use, in order to avoid the existence of accumulated water in the pump house affecting the normal use of the power distribution cabinet, the water supply pump station system is generally also provided with a sewage unit. The sewage unit usually consists of a sewage pump, a sewage pipe and a liquid level sensor. A water collecting pit is opened at the bottom of the pump house. The sewage pump is arranged in the water collecting pit. The water outlet end of the sewage pipe is arranged outside the pump house. The liquid level sensor is used to detect the liquid level in the pump house. The sewage pump, the liquid level sensor and the control unit are electrically connected. When the liquid level sensor detects that the liquid level in the pump house reaches the preset water level, the control unit will control the sewage pump to start, and the accumulated sewage in the pump house will be discharged outside to ensure the use safety of the components in the pump house.

[0032] At present, a door (or a skylight) is arranged in the pump house to open and close relative to the pump house, so as to install and maintain the equipment in the pump house. Due to the existence of the door, when the water level outside the pump house rises due to flood or other conditions, the sewage is collected and extruded to the door, so that the door is instantaneously broken, and a large amount of sewage will quickly enter the pump house, impact the normally running water pump set, cause the water pumps on the water pump set to be abnormally stopped, and cause the water pump set to be damaged. Even if the existing pump house is provided with a matched sewage discharge unit, the sewage discharge unit cannot discharge the large amount of sewage instantaneously entering the pump house. Therefore, the current water supply pump station system has the problems that when the sewage water level outside the pump house rises due to flood disaster or other conditions, the water pump set is prone to abnormal stop, the water pump set is damaged, and great economic loss is caused.

[0033] To solve the above problems, the application provides a water supply pump station system, which monitors the liquid level outside the pump house and adapts the start and stop of each water pump of the water pump set, so as to reduce the economic loss of the water pump set caused by flood disaster.

[0034] The technical solutions of the application and how the technical solutions solve the above technical problems will be described in detail in specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the application will be described below with reference to the drawings.

[0035] Referring to FIGS. 1-6, the application provides a water supply pump station system, which includes a control unit 100, a pump house 300, a water pump set 200 and a control unit, the water pump set 200 is located in the pump house 300; the control unit includes a first liquid level detection piece 800, the first liquid level detection piece 800 and the water pump set 200 are electrically connected with the control unit 100; the first liquid level detection piece 800 is used for detecting the liquid level outside the pump house 300 and sending a liquid level signal to the control unit 100, and the control unit 100 receives the liquid level signal to control at least part of the water pumps in the water pump set 200 to stop running.

[0036] It can be understood that the water pump set 200 is a main water supply unit, and the water pump set 200 can be a combination of multiple small water pump sets 200 or a single water pump set 200. Each water pump set 200 includes multiple water pumps, and each water pump can be connected to different water supply users or the same water supply users; starting, stopping or changing the speed of each water pump can realize multiple water supply modes.

[0037] In the present application, the control unit 100 adopts a similar programming control unit 100 (PLC control system) as the existing water supply pump house 300 system. One of the functions of the control unit 100 is to enable the start and stop control of each water pump on the water pump unit 200 and the control of the speed of each water pump, so as to supply water according to the user's demand.

[0038] In order to enable the water supply pump station system of the present application to cope with the change of water level outside the pump house 300, the present application also provides a prevention and control unit. According to the change of liquid level outside the pump house 300, the prevention and control unit can send a liquid level signal to the control unit 100, so that the control unit 100 controls each water pump on the water pump unit 200 to cope with possible emergencies and ensure the safety of the water pump unit 200.

[0039] Specifically, the prevention and control unit includes a first liquid level detection member 800. The first liquid level detection member 800 is used to detect the liquid level outside the pump house 300. For this purpose, the first liquid level detection member 800 can be a liquid level sensor, or a plurality of liquid level sensors arranged up and down. The liquid level sensor can be a water level probe, a float type liquid level sensor, a capacitive liquid level sensor, etc.

[0040] The installation position of the first liquid level detection member 800 can be located outside the pump house 300 and connected to the pump house 300 (or connected to the pump house 300 through a connecting member). The first liquid level detection member 800 can also be arranged in the pump house 300, as long as the detection end of the first liquid level detection member 800 is located outside the pump house 300, so as to ensure that the first liquid level detection member 800 can detect the liquid level outside the pump house 300.

[0041] The first liquid level detection member 800 is electrically connected to the control unit 100. When the water level outside the pump house 300 rises to exceed the safe water level due to flood disaster or other situations, the first liquid level detection member 800 feeds back the detected liquid level signal to the control unit 100. The control unit 100 controls all or part of the water pumps on the water pump unit 200 to stop running according to the received liquid level signal. At this time, since part of the water pumps on the water pump unit 200 have stopped running, even if the sewage outside the pump house 300 suddenly enters the pump house 300 and impacts the water pump unit 200, it will not cause the water pump unit 200 to stop abnormally, thereby avoiding the problem that the water pump unit 200 is easily damaged by external water flow impact.

[0042] In a possible implementation, the first liquid level detection member 800 comprises at least two external liquid level sensors, the two external liquid level sensors are arranged in an upper-lower interval, the external liquid level sensor at the lower part is used to detect the first liquid level outside the pump house 300 and send a first liquid level signal to the control unit 100, and the control unit 100 receives the first liquid level signal to control the water pump set 200 to stop running; the external liquid level sensor at the upper part is used to detect the second liquid level outside the pump house 300 and send a second liquid level signal to the control unit 100, and the control unit 100 receives the first liquid level signal and the second liquid level signal to control the water pump set 200 to stop running.

[0043] It can be understood that in the case of flood disaster outside the pump house 300, the water level in the pump house 300 gradually rises to contact the first liquid level detection member 800; there is also a case of instantaneous contact with the first liquid level detection member 800 due to sewage fluctuation.

[0044] If in the second case, the sewage outside the pump house 300 instantaneously contacts the first liquid level detection member 800, at this time, the first liquid level detection member 800 feeds back a signal to the control unit 100, and the control unit 100 controls the water pump set 200 to stop running. After the first liquid level detection member 800 cannot detect the liquid level signal outside the pump house 300, the control unit 100 will start the water pump according to the use requirements of the user end. If the process is repeated, the water pump set 200 will be repeatedly started and stopped, which affects the service life of the water pump set 200.

[0045] To avoid the water pump set 200 from being repeatedly started and stopped due to too fast change of the liquid level outside the pump house 300, which affects the service life of the water pump, the first liquid level detection member 800 of the present application comprises at least two external liquid level sensors, and the two external liquid level sensors are arranged in an upper-lower interval. The two external liquid level sensors can be arranged outside the pump house 300 and connected with the pump house 300. Alternatively, the two external liquid level sensors are arranged inside the pump house 300, but the sensing end of the external liquid level sensor is arranged outside the pump house 300.

[0046] The two external liquid level sensors are both used to detect the water level outside the pump house 300, but the control unit 100 will control the water pump set 200 to stop running or partially stop running according to different signals received.

[0047] Specifically, the lower external liquid level sensor is used to detect the first liquid level outside the pump house 300 and send a first liquid level signal to the control unit 100, and the control unit 100 receives the first liquid level signal to control the water pump unit 200 to stop running; the upper external liquid level sensor is used to detect the second liquid level outside the pump house 300 and send a second liquid level signal to the control unit 100, and the control unit 100 receives the first liquid level signal and the second liquid level signal to control the water pump unit 200 to stop running.

[0048] When the instantaneous sewage outside the pump house 300 contacts the upper external liquid level sensor due to sewage fluctuation, but most of the time in this process does not contact the lower external liquid level sensor, at this time, the signal feedback of the two external liquid level sensors indicates that the liquid level outside the pump house 300 is not gradually rising under natural conditions, at this time, the sewage outside the pump house 300 will not be enough to cause a safety hazard to the water pump unit 200 inside the pump house 300, and the water pump unit 200 can normally supply water to the user under the action of the control unit 100.

[0049] If the sewage outside the pump house 300 is gradually collected to gradually raise the liquid level outside the pump house 300, the sewage outside the pump house 300 will preferentially contact the lower external liquid level sensor, at this time, when the control unit 100 receives the signal of the lower external liquid level sensor, it will control part of the water pump unit 200 to stop running to cope with the possible safety situation. When the water pump outside the pump house 300 gradually rises and contacts the upper external liquid level sensor, at this time, the upper external liquid level sensor will also send a signal to the control unit 100, at this time, the control unit 100 receives the signals of the two external liquid level sensors, which indicates that the liquid level outside the pump house 300 has reached the preset critical liquid level, and all the water pumps on the water pump unit 200 need to be stopped to cope with the sewage that may enter the pump house 300 and avoid abnormal shutdown of the water pumps on the water pump unit 200.

[0050] As shown in FIG. 1 and FIG. 2, in the present application, the first liquid level detection member 800 includes three external liquid level sensors, which are sequentially and spaced apart from top to bottom outside the pump house 300, for the convenience of description, the three external liquid level sensors are sequentially and spaced apart from bottom to top as the first external liquid level sensor 810, the second external liquid level sensor 820 and the third external liquid level sensor 830.

[0051] The combined principle of the first liquid level detection member 800 and the water pump unit 200 in the present application is as follows:

[0052] When the water level outside the pump house 300 gradually rises, the first external liquid level sensor 810 will be in contact with the sewage, the first external liquid level sensor 810 detects the corresponding liquid level signal, and feeds back the liquid level signal to the control unit 100. The control unit 100 will control the water pump assembly to stop running.

[0053] When the water level outside the pump house 300 continues to rise, it will be in contact with the second external liquid level sensor 820, and the second external liquid level sensor 820 detects the corresponding liquid level signal and sends the signal to the control unit 100. At this time, the control unit 100 receives the detection signal of the first external liquid level sensor 810 and the detection signal of the second external liquid level sensor 820, and the control unit 100 controls the number of water pumps in the water pump unit 200 to continue to decrease, and controls the rotating speed of the running water pumps to decrease.

[0054] When the water level outside the pump house 300 continues to rise, it will be in contact with the third external liquid level sensor 830, and the third external liquid level sensor 830 detects the corresponding liquid level signal and sends the signal to the control unit 100. At this time, the control unit 100 receives the detection signal of the first external liquid level sensor 810, the detection signal of the second external liquid level sensor 820 and the detection signal of the third external liquid level sensor 830, indicating that the water level outside the pump house 300 has reached the preset warning water level, and the control unit 100 controls all the water pumps in the water pump unit 200 to stop running, so as to cope with the sewage that may enter the pump house 300 and avoid the abnormal stop of the water pumps in the water pump unit 200.

[0055] Similarly, when the water level outside the pump house 300 abnormally contacts the second external liquid level sensor 820 but does not contact the first external liquid level sensor 810, the control unit 100 receives the detection signal of the second external liquid level sensor 820, and the control unit 100 will not control the water pumps in the water pump unit 200 to stop running. Similarly, when the sewage outside the pump house 300 contacts the third external liquid level sensor 830 alone, the control unit 100 will not control all the water pumps in the water pump unit 200 to stop running.

[0056] In this application, the first liquid level detection member 800 adopts a plurality of external liquid level sensors arranged in sequence from top to bottom at intervals, which can cope with the abnormal situation of the water level outside the pump house 300, avoid the repeated start and stop of the water pumps in the water pump unit 200, and ensure the service life of the water pumps in the water pump unit 200.

[0057] At the same time, the cooperation of the plurality of external liquid level sensors and the control unit 100, as well as the control of the start, stop and rotating speed of the water pumps in the water pump unit 200, can timely reduce the number of water pumps in the water pump unit 200 according to the change of the liquid level outside the pump house 300, prevent the sudden drop of system pressure caused by abnormal stop, and reduce the loss of the water pump unit 200.

[0058] In a possible implementation, the prevention and control unit further comprises a mounting mechanism, the mounting mechanism comprising a mounting piece 720 and a lifting assembly 710, each external liquid level sensor being arranged on the mounting piece 720 in sequence, and the lifting assembly 710 being configured to adjust the mounting height of the mounting piece 720.

[0059] It can be understood that, according to the arrangement position of the door on the pump house 300, the number of the door, the material of the door, and the firmness of the connection lock between the door and the pump house 300 (or the connection lock between the doors), the door of the pump house 300 has different blocking forces for the floodwater at the same liquid level. Therefore, in order to enable the external liquid level sensors of the first liquid level detection piece 800 to adapt to different installation environments (actual working conditions on site), the prevention and control unit of the present application further comprises a mounting mechanism.

[0060] Specifically, as shown in FIG. 2, the mounting mechanism comprises a mounting piece 720 and a lifting assembly 710. The mounting piece 720 can adopt a plate structure or a rod structure or other special-shaped structures, and is configured to fix each external liquid level sensor. In the present application, the mounting piece 720 is a plate structure, the lifting assembly 710 is located on one side of the mounting piece 720, and each external liquid level sensor is located on the other side of the mounting piece 720. Each external liquid level sensor is fixed to the mounting piece 720 by means of bolts or welding.

[0061] The lifting assembly 710 is configured to change the mounting height of the mounting piece 720. The change of the mounting height of the mounting piece 720 can drive the change of the mounting height of each external liquid level sensor, so as to adapt to different installation environments. The lifting assembly 710 can adopt an existing drag chain moving assembly, or an electric sliding module, etc., to change the mounting position of the mounting piece 720.

[0062] In the present application, as shown in FIG. 1 and FIG. 2, the lifting assembly 710 comprises a mounting bracket, a driving motor 712, a rotating rod 714 and a connecting sleeve 715. The mounting bracket comprises a connecting plate 711, the connecting plate 711 is fixed to the outer wall of the pump house 300 and arranged close to the bottom of the pump house 300, and a first mounting seat 713 and a second mounting seat 717 are arranged on the connecting plate 711 in an up-down interval. The rotating rod 714 is located between the first mounting seat 713 and the second mounting seat 717, and is rotatably connected to at least one of the first mounting seat 713 or the second mounting seat 717. The rotating rod 714 can be a whole screw rod, and a threaded segment 716 can also be arranged on the rotating rod 714. The connecting sleeve 715 is at least one threaded sleeve, which is sleeved on the rotating rod 714 and threadedly connected to the rotating rod 714, and the connecting sleeve 715 is fixed to the mounting piece 720. The driving motor 712 is a servo motor or a stepping motor, which can be controlled by a PMW signal to start, stop, rotate and control the rotating speed. The driving motor 712 and the upper end of the rotating rod 714 are coaxially connected.

[0063] The principle of using the lifting assembly 710 is as follows:

[0064] When it is necessary to change the mounting position of the mounting member 720, the driving motor 712 is controlled by a signal to rotate, the driving motor 712 drives the rotating rod 714 to rotate, the rotating rod 714 drives the connecting sleeve 715 to move up and down, the connecting sleeve 715 drives the mounting member 720 to move up and down, thereby changing the mounting position of each external liquid level sensor on the mounting member 720 to adapt to different installation environments of the pump house 300.

[0065] The driving motor 712 can be controlled independently, or the driving motor 712 can be electrically connected with the control unit 100 and controlled by the control unit 100.

[0066] In the present application, a scale 718 is arranged vertically on the connecting plate 711 to check the mounting position of each external liquid level sensor, so that the mounting position of each external liquid level sensor can be determined to ensure that the mounting position of each external liquid level sensor meets the preset requirements.

[0067] In a possible implementation, the pump house 300 is provided with at least one house door which is opened and closed relative to the pump house 300; the control unit further comprises an automatic door locking mechanism, the automatic door locking mechanism is electrically connected with the control unit 100, and the control unit 100 receives the liquid level signal outside the pump house 300 to control the automatic door locking mechanism to reinforce the house door.

[0068] It can be understood that the control unit 100 needs to be mounted on an electric control box (or a control cabinet), and the installation position of the electric control box needs to be convenient for the operator to operate, and therefore the installation height of the electric control box is adapted to the height of the operator.

[0069] Meanwhile, the house door provided on the pump house 300 can facilitate the maintenance and installation of each component in the pump house 300. The house door can be provided with one or two doors which are arranged in a pair. The house door is provided with a door lock to lock the house door and the door frame of the pump house 300 or to lock the house door and the other door which is arranged in a pair. The house door is provided with a door lock to prevent non-working personnel from entering the pump house 300 and affecting the use of the internal components of the pump house 300.

[0070] However, the door lock provided on the house door has poor connection strength for the house door and the pump house 300 (or the other door), and when the water level outside the pump house 300 is high enough, the water pressure increases, which can cause the locking effect of the door lock to fail, forcing the house door to open, and a large amount of sewage (flood) will enter the pump house 300 in a short time. In addition to impacting the water pump set 200, a large amount of sewage also exists in the case of submerging the electric control box, which seriously affects the normal use of the pump house 300.

[0071] To this end, in order to avoid as much as possible the flood disaster, the sewage outside the pump house 300 enters the pump house 300. The automatic door locking mechanism is provided, which can reinforce the door and increase the connection strength between the door and the pump house 300 (or the connection strength between the door and the door), and has a better resistance effect on the impact or extrusion of the sewage outside the pump house 300, so as to prevent the sewage from entering the pump house 300 as much as possible and ensure the safety of the equipment in the pump house 300.

[0072] The starting of the automatic door locking mechanism is based on the check signal of the third external liquid level sensor 830, which means that when the water level outside the pump house 300 is higher than the preset value, the door lock will not be able to ensure the stable connection of the door and the pump house 300 (or another door), at this time, the automatic door locking mechanism is started to reinforce the door to avoid as much as possible the sewage from entering the pump house 300.

[0073] In one possible implementation, the number of doors is two; the automatic door locking mechanism includes a movable locking piece 920, a fixed locking piece 950, and an electric drive assembly, the movable locking piece 920 is in sliding connection with one of the doors, and the fixed locking piece 950 is fixed with the other door; the electric drive assembly and the control unit 100 are electrically connected; the control unit 100 receives the liquid level signal outside the pump house 300 to control the electric drive assembly to drive the movable locking piece 920 to move, and the movable locking piece 920 is locked with the fixed locking piece 950.

[0074] It can be understood that the two doors are arranged left and right and are opposite to each other along the pump house 300, and a door lock is arranged between the two doors to realize the opening and closing of the two doors.

[0075] The movable locking piece 920 is arranged on one of the doors in sliding manner, the fixed locking piece 950 is arranged on the other door in fixed manner, and the fixed locking piece 950 is located on the sliding path of the movable locking piece 920, so that when the fixed locking piece 950 and the movable locking piece 920 are locked, the reinforcement of the two doors can be realized, so as to avoid as much as possible the sewage outside the pump house 300 from entering the pump house 300 through the two doors. The movable locking piece 920 can slide horizontally or obliquely on the door to ensure that the movable locking piece 920 can cross the opening gap between the two doors, and then lock with the fixed locking piece 950 on the other door to achieve the corresponding effect.

[0076] Specifically, the movable locking piece 920 and the fixed locking piece 950 are located outside the two doors, for the convenience of description, the two doors are divided into a first door 310 and a second door 320, wherein the movable locking piece 920 is installed in cooperation with the first door 310, and the second door 320 is fixed with the fixed locking piece 950.

[0077] As shown in FIG. 3, FIG. 4 and FIG. 6, the mobile lock 920 is in a horizontally arranged rod structure, the first door 310 is externally fixed with a sliding seat 930, and the mobile lock 920 is slidably connected through the sliding seat 930, so as to realize the sliding arrangement of the mobile lock 920 outside the first door 310. The fixed lock 950 is in a sleeve structure similar to the sliding seat 930, and the fixed lock 950 is fixed outside the second door 320. When the mobile lock 920 moves horizontally, the mobile lock 920 partially enters the fixed lock 950, so as to realize the locking of the fixed lock 950 and the mobile lock 920.

[0078] The electric drive assembly is used to drive the horizontal reciprocating movement of the mobile lock 920, and the electric drive assembly comprises a rotating motor 980 and a rotating gear 960 and a mobile rack 970 used in cooperation. The rotating motor 980 is a servo motor or a stepping motor, and the rotating motor 980 is electrically connected with the control unit 100. The rotating motor 980 is located inside the first door 310 and is fixedly connected with the first door 310, and the output shaft of the rotating motor 980 is rotatably connected with the first door 310 through a bearing. The rotating gear 960 is coaxially arranged outside the first door 310 and the rotating motor 980. The mobile rack 970 is arranged on the mobile lock 920, and the mobile rack 970 is arranged along the length direction of the mobile lock 920, and the mobile rack 970 is engaged with the rotating gear 960.

[0079] The use principle of the automatic door locking mechanism is as follows:

[0080] When the flood disaster occurs, the water level outside the pump house 300 gradually rises, and when the liquid level outside the pump house 300 rises to a preset water level (in this application, when the first external liquid level sensor 810, the second external liquid level sensor 820 and the third external liquid level sensor 830 simultaneously detect the liquid level signal, it is the preset liquid level outside the pump house 300), the control unit 100 receives the signal of the first liquid level sensor 800, and the control unit 100 controls the rotating motor 980 to start, and the rotating motor 980 rotates to drive the rotating gear 960 to rotate, and the rotating gear 960 rotates to drive the mobile rack 970 and the mobile lock 920 to move, and the mobile lock 920 moves to partially enter the fixed lock 950, and then is locked with the fixed lock 950, so as to realize the reinforcement interlocking of the two doors, so as to prevent the flood fluid from impacting the pump house 300 as much as possible to enter the pump house 300 to flood the pump set 200 and other systems.

[0081] The automatic door locking mechanism can not only realize the interlocking reinforcement of the two doors, but also can not affect the normal use of the two doors when the two doors do not need to be reinforced. Therefore, after the flood recedes (when the liquid level outside the pump house 300 is lower than the liquid level that can be detected by the first external liquid level sensor 810), the control unit 100 controls the rotating motor 980 to rotate reversely to unlock the moving lock piece 920 and the fixed lock piece 950, so as to ensure the normal use of the two doors.

[0082] In order to limit the moving distance of the moving lock piece 920, the control unit 100 drives the start and stop and rotation direction of the rotating motor 980. As shown in FIGS. 3 and 5, the automatic door locking mechanism further comprises two limiting assemblies, each of which comprises a light sensor 910 and a sensor blocking piece 940 used in cooperation. The two light sensors 910 are electrically connected with the control unit 100. One of the light sensors 910 is fixed on the first door 310 and located on the left side of the sliding seat 930, and the other light sensor 910 is fixed on the second door 320 and located on the right side of the fixed lock piece 950. The two sensor blocking pieces 940 are arranged on the moving lock piece 920 in a spaced manner, one of which is located in the middle of the moving lock piece 920, and the other is close to the right end of the moving lock piece 920.

[0083] When the moving lock piece 920 and the fixed lock piece 950 are locked: the rotating motor 980 rotates and drives the moving lock piece 920 to move to the right, and when the sensor blocking piece 940 located on the right side of the moving lock piece 920 and the light sensor 910 on the second door 320 are in contact, the light sensor 910 detects that the moving lock piece 920 and the fixed lock piece 950 are locked and the moving lock piece 920 is moved to the position, at this time, the light sensor 910 sends a position signal to the control unit 100, and the control unit 100 controls the rotating motor 980 to stop rotating.

[0084] When the moving lock piece 920 and the fixed lock piece 950 are unlocked: the rotating motor 980 reverses to rotate and drives the moving lock piece 920 to move to the left, and when the sensor blocking piece 940 located in the middle of the moving lock piece 920 and the light sensor 910 on the first door 310 are in contact, the light sensor 910 detects that the moving lock piece 920 and the fixed lock piece 950 are unlocked and the moving lock piece 920 is moved to the position, at this time, the light sensor 910 sends a position signal to the control unit 100, and the control unit 100 controls the rotating motor 980 to stop rotating.

[0085] In a possible implementation, a main sewage discharge unit and an auxiliary sewage discharge unit are further included, and the main sewage discharge unit and the auxiliary sewage discharge unit are both used for discharging sewage in the pump house 300.

[0086] It can be understood that, in order to avoid the water in the pump house 300 caused by the explosion of the water pipe (the water supply pipeline connected with the pump set 200) or other situations, so as to affect the normal use of each equipment in the pump house 300. The current water supply pump station washing system also has a sewage unit for discharging sewage into the pump house 300. However, the current sewage unit has no prevention and control effect, and when the sewage unit pipeline or pump body fails, the pump house 300 is at risk of being flooded. And when the flood disaster occurs, the sewage in the pump house 300 enters the pump house 300, and the sewage discharge efficiency of the sewage unit is limited, and the sewage in the pump house 300 cannot be discharged in time.

[0087] Therefore, the present application provides a main sewage unit and an auxiliary sewage unit. The main sewage unit is equivalent to the existing sewage unit. When the liquid level in the pump house 300 exceeds the preset liquid level, the main sewage unit works to discharge the sewage in the pump house 300. The auxiliary sewage unit can be used with the main sewage unit. When the liquid level in the pump house 300 exceeds the safety liquid level, the auxiliary sewage unit and the main sewage unit work at the same time to improve the discharge efficiency of the sewage in the pump house 300 and ensure the safety of each equipment in the pump house 300. At the same time, the auxiliary sewage unit is equivalent to the standby sewage unit of the main sewage unit. When the main sewage unit fails, the auxiliary sewage unit can replace the work of the main sewage unit to discharge the sewage in the pump house 300, so as to avoid the influence of the collected sewage in the pump house 300 on the safety of each equipment in the pump house 300.

[0088] In one possible implementation, the main sewage unit includes a drain pipe 440, at least one sewage pump and a second liquid level detection member 430; one end of the drain pipe 440 is located outside the pump house 300 and is higher than the installation position of the first liquid level detection member 800; the sewage pump is located in the pump house 300 and is connected with the drain pipe 440 through a pipeline; the sewage pump and the second liquid level detection member 430 are electrically connected with the control unit 100; the second liquid level detection member 430 is used for detecting the liquid level in the pump house 300 and sending a liquid level signal to the control unit 100, and the control unit 100 receives the liquid level signal to control the operation of the at least one sewage pump.

[0089] It can be understood that the second liquid level detection member 430 and the first liquid level detection member 800 have the same function of detecting the liquid level. The second liquid level detection member 430 can include a liquid level sensor or be composed of a plurality of liquid level sensors. The second liquid level detection member 430 is used for detecting the change of the liquid level in the pump house 300, so as to ensure that the sewage pump can operate to discharge the sewage in the pump house 300 when the liquid level in the pump house 300 exceeds the preset liquid level.

[0090] In the application, as shown in FIG. 1, a sump is arranged in the pump house 300, and a sewage pump is arranged in the sump. The sewage pump is connected to the drain pipe 440 through a pipeline. According to the prevention and control requirements, a check valve and a maintenance valve can be arranged on the pipeline. The drain pipe 440 is fixed to the top of the pump house 300 through a fixing member, and the water outlet end of the drain pipe 440 is located outside the pump house 300 and is installed close to the upper part of the pump house 300, so as to avoid that the sewage entering the pump house 300 cannot be discharged in time from the drain pipe 440 in the case of flood disaster.

[0091] The operation principle of the main sewage unit is as follows:

[0092] The sewage entering the pump house 300 is preferentially collected in the sump. When the sewage in the sump overflows or the water level in the sump reaches a preset value, the second liquid level detection member 430 detects the liquid level signal in the pump house 300 and sends the liquid level signal to the control unit 100. The control unit 100 receives the liquid level signal to control the operation of at least one sewage pump. The sewage pump discharges the sewage from the drain pipe 440 to the pump house 300, so as to avoid that the equipment in the pump house 300 is flooded and the operation safety of the equipment is affected.

[0093] In a possible implementation, the sewage pump includes a first sewage pump 410 and a second sewage pump 420, and the second liquid level detection member 430 includes two internal liquid level sensors. The two internal liquid level sensors are arranged in an upper-lower interval. The internal liquid level sensor located at the lower part is used to detect the first liquid level in the pump house 300 and send the first liquid level signal to the control unit 100. The control unit 100 receives the first liquid level signal to control the operation of the first sewage pump 410. The internal liquid level sensor located at the upper part is used to detect the second liquid level in the pump house 300 and send the second liquid level signal to the control unit 100. The control unit 100 receives the second liquid level signal to control the operation of the second sewage pump 420.

[0094] It can be understood that the maximum drainage capacity of each type of sewage pump per unit time is certain, and the accumulated water amount in the pump house 300 is variable. Therefore, the sewage pump can be started according to the different accumulated water amounts in the pump house 300 to reduce energy consumption.

[0095] As shown in FIG. 1, in the application, two sewage pumps are arranged, which are a first sewage pump 410 and a second sewage pump 420. The first sewage pump 410 and the second sewage pump 420 are both located in the sump and are both connected to the drain pipe 440 through the installation pipeline. The maintenance valve and the check valve are arranged on each installation pipeline. The first sewage pump 410 and the second sewage pump 420 are both electrically connected to the control unit 100.

[0096] In order to enable the first sewage pump 410 and the second sewage pump 420 according to different water levels in the pump house 300, as shown in FIG. 1, the second liquid level detection member 430 in the application includes two internal liquid level sensors, which are fixed on the connecting frame 450 in an up-down arrangement, the connecting frame 450 is fixed in the pump house 300 and is arranged close to the bottom of the pump house 300, and the installation height of the connecting frame 450 and the pump house 300 is adjustable to ensure that the internal liquid level sensor meets the use requirements. Both internal liquid level sensors are electrically connected with the control unit 100. For convenience of description, the internal liquid level sensor located in the lower installation position is called the first internal liquid level sensor 432, and the internal liquid level sensor located in the upper position is called the second internal liquid level sensor 431.

[0097] The enabling principle of the first sewage pump 410 and the second sewage pump 420:

[0098] The sewage entering the pump house 300 will be preferentially collected in the sump, when the sewage in the sump overflows the sump or the water level in the sump reaches a preset value, the first internal liquid level sensor 432 detects the first liquid level signal in the pump house 300 and sends the first liquid level signal to the control unit 100, and the control unit 100 receives the first liquid level signal to control the first sewage pump 410 to run, and the first sewage pump 410 runs to guide the sewage out of the pump house 300 from the drain pipe 440.

[0099] When the sewage in the pump house 300 continues to collect, the water level in the pump house 300 rises and contacts the second internal liquid level sensor 431, the second internal liquid level sensor 431 detects the second liquid level signal in the pump house 300 and sends the second liquid level signal to the control unit 100, and the control unit 100 receives the second liquid level signal to control the second sewage pump 420 to also run, and the first sewage pump 410 and the second sewage pump 420 run at the same time to guide the sewage out of the pump house 300 from the drain pipe 440 to avoid the equipment in the pump house 300 being flooded and affecting the safe operation of the equipment.

[0100] In one possible implementation, the control unit 100 receives the first liquid level signal in the pump house 300 to control at least one water pump in the water pump unit 200 to run; the control unit 100 receives the second liquid level signal in the pump house 300 to control all the water pumps in the water pump unit 200 to stop running.

[0101] It can be understood that when the water level in the pump house 300 is too high, the water pump set 200 is also submerged, and the water level in the pump house 300 is abnormally high, which is usually two cases. One is that the internal pipeline is damaged and the pipe bursts, causing the water level in the pump house 300 to increase sharply in a short time; the second is that the flood disaster occurs outside the pump house 300, and the external sewage overflow enters the pump house 300, causing the water level in the pump house 300 to rise rapidly. No matter which of the two cases, there is a water flow impacting the water pump set 200, which may cause the water pump set 200 to be abnormally stopped. Therefore, in order to avoid the damage of the water pump set 200 in the pump house 300 due to the influence of the water level in the pump house 300, the control unit 100 can also control the start and stop of each water pump on the water pump set 200 according to the liquid level signal fed back by the first internal liquid level sensor 432 and the second internal liquid level sensor 431.

[0102] The working principle of the second liquid level detection member 430 and the water pump set 200 is as follows:

[0103] The sewage entering the pump house 300 will be collected in the sump first. When the sewage in the sump overflows the sump or the water level in the sump reaches a preset value, the first internal liquid level sensor 432 detects the first liquid level signal in the pump house 300 and sends the first liquid level signal to the control unit 100. The control unit 100 receives the first liquid level signal to control part of the water pumps on the water pump set 200 to stop running, reduce the running input of each water pump on the water pump set 200, and cope with the possible risks; at the same time, it also facilitates to provide part of the water supply function for the user end.

[0104] When the sewage in the pump house 300 continues to collect, the water level in the pump house 300 rises and contacts the second internal liquid level sensor 431. The second internal liquid level sensor 431 detects the second liquid level signal in the pump house 300 and sends the second liquid level signal to the control unit 100. The control unit 100 receives the second liquid level signal to control all the water pumps on the water pump set 200 to stop running.

[0105] The combination of the second liquid level detection member 430 and the water pump set 200 can avoid the possible damage to the water pump set 200 caused by the sudden increase of the water level in the pump house 300.

[0106] In a possible implementation, the auxiliary sewage discharge unit comprises a sewage discharge pipe 530 and a sewage discharge pump 510. One end of the sewage discharge pipe 530 is located outside the pump house 300 and is lower than the installation position of the first liquid level detection member 800, and the other end of the sewage discharge pipe 530 is connected with the drain pipe 440. The sewage discharge pipe 530 is provided with the first control valve 550 and the second control valve 540 arranged at intervals, and the first control valve 550 is adjacent to the drain pipe 440. The sewage discharge pump 510 is located in the pump house 300 and is connected with the sewage discharge pipe 530 through the connecting pipe 520. The connecting end of the connecting pipe 520 and the sewage discharge pipe 530 is located between the first control valve 550 and the second control valve 540. The first control valve 550, the second control valve 540 and the sewage discharge pump 510 are electrically connected with the control unit 100 respectively. The control unit 100 receives the liquid level signal in the pump house 300 to synchronously control the first control valve 550 to be closed, the second control valve 540 to be opened and the sewage discharge pump 510 to be operated. Or the control unit 100 synchronously receives the liquid level signal in the pump house 300 and the liquid level signal outside the pump house 300 to synchronously control the second control valve 540 to be closed, the first control valve 550 to be opened and the sewage discharge pump 510 to be operated.

[0107] It can be understood that, in order to avoid the main sewage discharge unit from being abnormal, so that the sewage in the pump house 300 cannot be discharged outside, and thus the equipment in the pump house 300 is flooded, the auxiliary sewage discharge unit is arranged in the application. The auxiliary sewage discharge unit can be used in combination with the main sewage discharge unit, or can be used alone.

[0108] Specifically, as shown in FIG. 1, one end of the sewage discharge pipe 530 is located outside the pump house 300 and is connected with the municipal drain ditch 600. The end of the sewage discharge pipe 530 located outside the pump house 300 is provided with an insect screen. The other end of the sewage discharge pipe 530 is connected with the drain pipe 440 in communication. The sewage discharge pipe 530 is provided with the first control valve 550, the second control valve 540 and a check valve. The first control valve 550 is adjacent to the drain pipe 440. The first control valve 550 and the second control valve 540 are electrically connected with the control unit 100.

[0109] The sewage discharge pump 510 is installed in the pump house 300 and is placed at the bottom of the pump house 300. The sewage discharge pump 510 is electrically connected with the control unit 100. The sewage discharge pump 510 is connected with the sewage discharge pipe 530 through the connecting pipe 520. The connecting position of the connecting pipe 520 and the sewage discharge pipe 530 is located between the first control valve 550 and the second control valve 540.

[0110] The principle of the auxiliary sewage discharge unit is as follows:

[0111] When no flood disaster occurs outside the pump house 300:

[0112] The sewage entering the pump house 300 will be preferentially collected in the sump. When the sewage in the sump overflows the sump or the water level in the sump reaches a preset value, the second internal liquid level sensor 431 detects a second liquid level signal in the pump house 300 and sends the second liquid level signal to the control unit 100, and the control unit 100 receives the second liquid level signal to synchronously control the operation of the sewage pump 510, the closing of the first control valve 550, and the opening of the second control valve 540. The sewage pump 510 operates to guide the sewage out of the pump house 300 from the sewage pipe 530. At this time, the main sewage unit can also be used for sewage discharge operation in the pump house 300. At this time, the main sewage unit may also have a power failure anomaly and be used abnormally, but the auxiliary sewage unit can be used normally to discharge the sewage in the pump house 300, so as to avoid the equipment in the pump house 300 being flooded and affecting the safe operation of the equipment.

[0113] When a flood disaster occurs outside the pump house 300:

[0114] When a flood disaster occurs outside the pump house 300, the water level outside the pump house 300 rises, and the first external liquid level sensor 810 outside the pump house 300 detects a liquid level signal, indicating that a flood disaster occurs outside the pump house 300 (or other pipe bursts cause sewage to collect outside the pump house 300).

[0115] At this time, part of the sewage enters the pump house 300 and is collected in the sump. When the sewage in the sump overflows the sump or the water level in the sump reaches a preset value, the second internal liquid level sensor 431 detects a second liquid level signal in the pump house 300 and sends the second liquid level signal to the control unit 100, and the control unit 100 receives the second liquid level signal to synchronously control the operation of the sewage pump 510, the closing of the second control valve 540, and the opening of the first control valve 550. The sewage pump 510 operates to guide the sewage out of the pump house 300 from the drainage pipe 440. At this time, the main sewage unit can also be used for sewage discharge operation in the pump house 300. At this time, the main sewage unit may also have a power failure anomaly and be used abnormally, but the auxiliary sewage unit can be used normally to discharge the sewage in the pump house 300, so as to avoid the equipment in the pump house 300 being flooded and affecting the safe operation of the equipment.

[0116] Since the drainage end of the drainage pipe 440 is higher than the sewage end of the sewage pipe 530, when a flood disaster occurs outside the pump house 300, the sewage end of the sewage pipe 530 will be submerged in the flood. At this time, the first control valve 550 needs to be controlled to be opened and the second control valve 540 needs to be controlled to be closed, so as to guide the sewage in the pump house 300 out of the pump house 300 from the drainage pipe 440, and ensure the safe use of the water pump unit 200 and other equipment in the pump house 300.

[0117] In the present application, the water supply unit (pump set 200), the main sewage unit, the auxiliary sewage unit, and the prevention and control unit are independent, and can act under the action of the control unit 100 according to the water level changes inside and outside the pump house 300 to meet the use requirements.

[0118] In the present application, alarm lights can also be installed inside and outside the pump house 300, and the alarm lights are electrically connected with the control unit 100. When the water level inside the pump house 300 reaches the preset value (the liquid level signal detected by the second internal liquid level sensor 431), the control unit 100 starts the alarm light inside the pump house 300 to flash (and / or beep) to achieve the alarm effect. Similarly, when the water level outside the pump house 300 reaches the preset value (the liquid level signal detected by the third external liquid level sensor 830), the control unit 100 starts the alarm light outside the pump house 300 to flash (and / or beep) to achieve the alarm effect.

[0119] In the present application, the control unit 100 is equipped with a frequency conversion cabinet, and HMI design can be performed on the frequency conversion cabinet to achieve the purpose of manual operation on site.

[0120] Meanwhile, the control unit 100 of the present application can also be equipped with a remote control module to realize remote control.

[0121] Based on the water supply pump station system of the present application, the present application has the following advantages compared with the prior art:
