Description

Technical Field

[0001] This application relates to the field of sewage discharge technology, and in particular to a pressurized sewage discharge system. Background Technology

[0002] Sewage pumps are key equipment in environmental protection and wastewater treatment, and are commonly used in municipal engineering, industrial, and water conservancy construction. Sewage pumps are typically installed underwater to discharge wastewater from sewage tanks.

[0003] In actual operation, sewage tanks often contain a large number of solid impurities and suspended solids. These impurities can easily enter the pump body with the sewage, causing blockage of the internal flow channel of the sewage pump. Since the sewage pump is in a relatively harsh underwater environment, blockage is difficult to deal with quickly, resulting in a decrease in the sewage discharge speed and affecting the working efficiency of the sewage pump. Summary of the Invention

[0004] This application provides a pressurized sewage discharge system that enables operators to promptly assess the condition of impurities in the sewage tank and the operational status of the sewage discharge components, facilitating timely sewage discharge and equipment maintenance, and ensuring the reliability of the system's sewage discharge.

[0005] This application provides a pressurized sewage discharge system, including a guide rod, a sewage discharge assembly, and a pressure detection device, wherein the guide rod is fixed to the mounting surface;

[0006] The sewage discharge assembly includes: a sewage pump and a connecting pipe, wherein the connecting pipe is connected to the sewage pump, and a connecting device is provided between the connecting pipe and the sewage pump;

[0007] The guide cover has a fixing part and a guiding part, wherein the fixing part is connected to the connecting device, and the guiding part is slidably engaged with the guide rod so that the sewage discharge assembly can move up and down along the guide rod;

[0008] A pressure detection device is installed in the connecting pipe, and the pressure detection device is used to detect the pressure inside the connecting pipe.

[0009] The pressure detection device enables real-time monitoring of the sewage discharge assembly's operating status. The sliding cooperation between the guide rod and the guide cover facilitates the assembly's lifting and lowering movement. Combined with real-time monitoring of pipeline pressure, the pressure detection device allows operators to promptly assess the level of impurities in the sewage tank and the operational status of the sewage discharge assembly, facilitating timely sewage discharge and equipment maintenance, and preventing excessive accumulation of impurities in the connecting pipes. Furthermore, the fluid disturbance generated as the sewage discharge assembly moves up and down along the guide rod via the guide cover helps expel impurities and accelerates pressure relief in the connecting pipes. The coordinated design of the guide structure and guide rod also enhances the stability of the pressurized sewage discharge system and extends the service life of the components.

[0010] In one possible implementation, the connecting pipe is provided with an openable and closable drain port, which is used to open and drain when the pressure inside the connecting pipe is greater than a preset pressure value.

[0011] By providing a drain port on the connecting pipe, it is possible to quickly clean the dirt inside the connecting pipe when the pressure is abnormal, thereby relieving pressure, maintaining the pressure of the connecting pipe within a safe range, ensuring the operating efficiency of the drain component, reducing maintenance costs, and extending the service life of the equipment.

[0012] In one possible implementation, a dirt-blocking screen is provided inside the connecting pipe, and the drain outlet is located between the dirt-blocking screen and the water inlet of the connecting pipe.

[0013] In this way, the dirt-blocking net can intercept dirt, and the dirt can be discharged from the connecting pipe by opening the drain outlet.

[0014] In one possible implementation, the pressurized sewage system further includes a control device electrically connected to the pressure detection device, which controls the opening and closing of the sewage outlet based on the detection result of the pressure detection device.

[0015] The pressure detection device collects pressure data from the connecting pipe in real time and transmits it to the control device. When the detected pressure exceeds the preset value, the control device sends an opening command to the actuator of the drain outlet. The drain outlet opens, allowing waste to be discharged manually or by flushing with water, thus quickly releasing the pressure in the connecting pipe. Furthermore, the control device can also link a lifting device to drive the drain assembly to adjust its height along the guide rod. When the detected pressure exceeds the preset pressure value, the lifting device raises the drain assembly. As the drain assembly rises, the distance between the drain pump and the mounting surface increases, preventing debris from accumulating at the outlet. Thus, through automated pressure monitoring and control of the drain outlet and / or lifting device, automatic pressure relief is possible when the connecting pipe pressure is abnormal, preventing leaks or equipment damage caused by excessive pressure and ensuring the drainage efficiency and service life of the booster-type drain system.

[0016] In one possible implementation, the guide cover is also provided with a lifting structure;

[0017] The pressurized sewage system further includes a lifting component, which is connected to the hoisting structure for lifting or lowering the sewage component.

[0018] Through the coordinated action of the hoisting structure and the guide rod, the sewage discharge assembly can be raised and lowered as a whole, avoiding the secondary displacement of the sealing surface caused by traditional split installation. This ensures that the connecting device always maintains the preset alignment during the lifting process, guaranteeing the operational stability of the pressurized sewage discharge system.

[0019] In one possible implementation, the control device is communicatively connected to the lifting device, and the control device sends instructions to the control device based on the detection results of the pressure detection device to drive the sewage discharge assembly to be lifted or lowered.

[0020] The lifting device generates driving force through a power source, which is transmitted to the sewage discharge assembly via the lifting components, causing it to rise or fall along the guide rod. During installation or maintenance, the height of the sewage discharge assembly can be adjusted by controlling the operation of the lifting device. The automatic lifting and lowering of the sewage discharge assembly is achieved through the cooperation of the pressure detection device, control device, and lifting device. This allows the sewage discharge assembly to adjust its height according to the actual sewage depth or debris accumulation, enabling it to adapt to sewage extraction at different heights and ensuring its versatility and applicability.

[0021] In one possible implementation, the sewage pump has an outlet, the peripheral wall of which is provided with an outlet flange surrounding the outlet, and the end of the connecting pipe has a connecting flange, the connecting flange and the outlet flange being connected to form a connection device between the sewage pump and the connecting pipe.

[0022] The fixing part is formed as a fixing groove that opens to one side of the guide cover along the thickness direction, and the connecting device is embedded in the fixing groove.

[0023] The open structure of the fixed slot allows the connecting device to be directly embedded into the fixed slot for positioning. Then, the output flange and connecting flange are simply connected and fixed with bolts to achieve the connection, eliminating the need for repeated flange position adjustments. This enables rapid positioning and installation of the sewage pump and connecting pipe, reducing the manual difficulty of flange connection operations. Furthermore, the mechanical limiting function of the fixed slot ensures the stability of the connecting device during lifting and lowering, avoiding the risk of seal failure and improving the reliability of underwater installation operations.

[0024] In one possible implementation, the fixing slot is provided with a positioning protrusion that divides the fixing slot into a first slot for accommodating the output flange and a second slot for accommodating the connecting flange.

[0025] The connecting flange is configured to fit against the output flange when it is located in the second slot.

[0026] The positioning protrusions provide positioning space for both the output flange and the connecting flange, ensuring accurate alignment during assembly and improving the stability and reliability of the connection. The design of the positioning protrusions also simplifies the assembly process, allowing installers to assemble the sewage discharge components more quickly and accurately, thus improving work efficiency.

[0027] In one possible implementation, the guide portion is formed as a guide groove, the guide portion is located on the edge of the guide cover along its own width direction, and the guide rod is fitted into the guide groove.

[0028] The sliding fit structure of the guide groove and the guide rod enables the sewage discharge component to automatically achieve axial alignment during the lifting process, eliminating the need for manual underwater adjustment. The sewage discharge component always maintains the predetermined trajectory during the lifting process, avoiding seal failure due to deviation, and reducing the underwater work intensity of the operators.

[0029] In one possible implementation, there are two guide rods, which are arranged at intervals along the width direction of the guide cover. There are two guide portions corresponding to the guide rods, which are respectively located on the two side edges of the guide cover along its own width direction.

[0030] With the symmetrical arrangement of double guide rods and double guide sections, stable lifting and lowering can be achieved without manual intervention, improving the efficiency and accuracy of flange docking. It solves the problem of offset that may be caused by unilateral guidance during the installation of traditional sewage pumps. Through the symmetrical distribution of guide rods and guide groove structure, it ensures that the flange of the sewage pump and the connecting pipe automatically stays aligned during the lifting and lowering process, reducing the number of manual adjustments and reducing the risk of leakage due to poor sealing.

[0031] In one possible implementation, there are at least two sewage pumps, including a first sewage pump and a second sewage pump. The output port of the first sewage pump is connected to the input port of the second sewage pump through the connecting pipe, and the output port of the second sewage pump is connected to an external connecting pipe through the connecting pipe.

[0032] There are two guide covers. One guide cover is connected to the connecting device at the output port of the first sewage pump and slides with the guide rod. The other guide cover is connected to the connecting device at the output port of the second sewage pump and slides with the guide rod.

[0033] Traditional sewage systems typically only have one sewage pump. This application improves sewage efficiency by designing a pump body structure with at least two pumps connected in series. In addition, the series pump body structure and the design of two guide covers allow the lifting and lowering trajectories of multiple sewage pumps to be uniformly controlled by guide rods, enabling synchronous lifting and lowering of multiple sewage pumps without manual intervention and ensuring stability during the lifting and lowering process.

[0034] In one possible implementation, the booster sewage system further includes a connecting frame, which is fixedly connected to each of the two sewage pumps.

[0035] The connecting frame is designed to span the installation area between two sewage pumps. As the two pumps rise and fall along the guide rod, the connecting frame maintains a constant distance between them, ensuring that the flange between the outlet and the connecting pipe is always aligned with the same axis. This rigid connection allows the two pump bodies to move synchronously during lifting and lowering. By integrating multiple sewage pumps into a unified motion unit through the connecting frame, the relative positional relationship is automatically maintained during lifting and lowering, reducing the frequency of manual intervention.

Detailed Implementation

[0049] 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 denote 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 as detailed in the appended claims.

[0050] Sewage pumps are key equipment in environmental protection and wastewater treatment, and are commonly used in municipal engineering, industrial, and water conservancy construction. Sewage pumps are typically installed underwater to discharge wastewater from sewage tanks.

[0051] In actual operation, sewage tanks often contain a large number of solid impurities and suspended solids. These impurities can easily enter the pump body with the sewage, causing blockage of the internal flow channel of the sewage pump, resulting in a decrease in the sewage discharge speed and affecting the working efficiency of the sewage pump. In addition, since the sewage pump is usually installed at the bottom of the sewage tank, in a relatively harsh underwater environment, its operating status is difficult to monitor. Once a blockage occurs, it is difficult to detect in time, leading to further deterioration of the problem.

[0052] To address the aforementioned issues, this application provides a pressurized sewage discharge system. This system utilizes a pressure detection device to achieve real-time monitoring of the sewage discharge component's operational status. The sliding cooperation between the guide rod and the guide cover enables the sewage discharge component to move up and down. Combined with real-time monitoring of pipeline pressure by the pressure detection device, this allows operators to promptly assess the level of impurities in the sewage tank and the operational status of the sewage discharge component, facilitating timely sewage discharge and equipment maintenance, and preventing excessive accumulation of impurities in the connecting pipe. Furthermore, the fluid disturbance generated when the sewage discharge component moves up and down along the guide rod via the guide cover helps to expel impurities and accelerates pressure relief in the connecting pipe. The coordinated design of the guide structure and guide rod also enhances the stability of the pressurized sewage discharge system and extends the service life of the components.

[0053] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0054] The following will combine Figures 1 to 4 The embodiments of this application will be described below.

[0055] Reference Figures 1 to 3 As shown in the figure, an embodiment of this application provides a pressurized sewage discharge system, including a guide rod 100, a sewage discharge assembly 200, a guide cover 300, and a pressure detection device 600. The guide rod 100 is fixed to the mounting surface. The sewage discharge assembly 200 includes a sewage pump 210 and a connecting pipe 220, the connecting pipe 220 being connected to the sewage pump 210, and a connecting device being provided between the connecting pipe 220 and the sewage pump 210. The guide cover 300 is provided with a fixing part 310 and a guiding part 320, wherein the fixing part 310 is connected to the connecting device, and the guiding part 320 is slidably engaged with the guide rod 100 to allow the sewage discharge assembly 200 to move up and down along the guide rod 100. The pressure detection device 600 is provided on the connecting pipe 220 and is used to detect the pressure inside the connecting pipe 220.

[0056] The guide rod 100 can be a rigid support structure that is vertically fixed to the mounting surface. Optionally, the guide rod 100 can be a metal rod or a composite material rod, used to provide a guide path for the lifting and lowering movement of the sewage discharge assembly 200.

[0057] The sewage discharge assembly includes a sewage pump 210 and a connecting pipe 220. The sewage pump 210 may be a submersible pump, and the connecting pipe 220 may be a stainless steel bellows. A connecting device is provided between the connecting pipe 220 and the sewage pump 210 to ensure the sealing of the fluid passage. Optionally, the connecting device may include a connecting flange. In some examples, connecting flanges for fixing are provided at the interfaces of the sewage pump 210 and the connecting pipe 220. Optionally, a sealing element, such as a rubber gasket, may also be provided at the interface of the sewage pump 210 and the connecting pipe 220.

[0058] The guide cover 300 can be a load-bearing component with a sliding structure. Optionally, the guide cover 300 can be injection molded from high-strength engineering plastic. In some examples, the fixing part 310 can be fastened to the connecting device through a slot structure, and the guide part 320 can form a sliding pair with the guide rod 100 through a slotted structure.

[0059] The pressure detection device 600 can be a sensor for real-time monitoring of the fluid pressure in the connecting pipe 220. Optionally, the pressure detection device 600 can be a diaphragm pressure transmitter, which is installed on the connecting pipe 220 and connected to the control system signal.

[0060] The pressure detection device 600 can be used to monitor the fluid pressure in the connecting pipe 220 in real time. Specifically, it can be implemented by using a pressure sensor or a pressure gauge. By embedding the detection element in the connecting pipe 220 or connecting it externally to the interface of the connecting pipe 220, the pressure signal can be converted into an electrical signal output.

[0061] Optionally, the pressure detection device 600 may be communicatively connected to an alarm, which in some examples will sound an alarm when the pressure detection device 600 detects that the internal pressure of the connecting pipe 220 exceeds a threshold.

[0062] Specifically, the guide rod 100 is vertically installed along the wall of the sewage tank to form a rigid support structure. The sewage pump 210 and the connecting pipe 220 are connected to form the sewage discharge assembly 200. The fixing part 310 of the guide cover 300 is connected to the connecting device, and the guide part 320 and the guide rod 100 form a sliding fit.

[0063] When the pressure detection device 600 detects that the internal pressure of the connecting pipe 220 exceeds the threshold, the operator can judge the condition of impurities in the sewage tank and the operation of the sewage discharge component 200 by the pressure condition. At this time, the sewage discharge component 200 can be moved along the guide rod 100 through the guide cover 300, so that the sewage discharge component 200 can be raised or lowered as a whole to clean the debris in the sewage discharge component 200 and relieve pressure.

[0064] As can be seen, the pressurized sewage system of this application realizes real-time monitoring of the operating status of the sewage component 200 through the pressure detection device 600, and realizes the lifting and lowering movement of the sewage component 200 through the sliding cooperation between the guide rod 100 and the guide cover 300. Combined with the real-time monitoring of pipeline pressure by the pressure detection device 600, it enables operators to judge the condition of impurities in the sewage tank and the operating status of the sewage component 200 in a timely manner, which facilitates timely sewage discharge and equipment maintenance, and prevents impurities from excessively depositing in the connecting pipe 220.

[0065] In addition, when the sewage discharge component 200 moves up and down along the guide rod 100 through the guide cover 300, the resulting fluid disturbance can help discharge impurities and accelerate the depressurization of the connecting pipe 220. The cooperative design of the guide structure and the guide rod 100 also enhances the stability of the pressurized sewage discharge system and extends the service life of the components.

[0066] In some embodiments, combined with Figure 1 and Figure 2 The sewage pump 210 has an output port, and the peripheral wall of the output port is provided with an output flange 212 surrounding the output port. The end of the connecting pipe 220 has a connecting flange 221. The connecting flange 221 and the output flange 212 are connected to form a connection device between the sewage pump 210 and the connecting pipe 220.

[0067] The output flange 212 of the sewage pump 210 can be an annular flange structure surrounding the output port. It can be connected to the output port by welding or integral molding, and is used to achieve a sealed connection with the connecting flange 221 of the connecting pipe 220 by bolt fastening. Optionally, refer to... Figure 1 The sewage pump 210 also includes an inlet 211, which can be set downwards.

[0068] Specifically, during installation, the guide rod 100 is pre-fixed to the bottom or side wall of the sewage tank. After the sewage pump 210 and the connecting pipe 220 are connected via a flange, the fixing part 310 of the guide cover 300 engages with the flange connection to ensure the position of the connecting device is fixed. The groove of the guide part 320 fits into the guide rod 100, so that the sewage discharge assembly 200 always moves along the axial direction of the guide rod 100 during the lifting and lowering process. When installation, disassembly, or maintenance is required, the operator can directly control the sewage discharge assembly 200 to rise and fall vertically along the guide rod 100, achieving precise alignment without entering the sewage environment.

[0069] The guide rod 100 is fixed to the mounting surface. The sewage discharge assembly 200 forms a connecting device with the connecting flange 221 through the output flange 212. The fixing part 310 of the guide cover 300 is connected to the connecting device, and the guiding part 320 is slidably engaged with the guide rod 100. This enables the sewage discharge assembly 200 to be smoothly raised and lowered along the guide rod 100, solving problems such as difficulty in alignment during manual underwater installation and uneven stress on the sealing surface. It also avoids diving safety risks that may be caused by installing the sewage pump 210, and improves installation efficiency and sealing reliability.

[0070] Furthermore, the fixing part 310 is formed as a fixing groove 311 that opens toward one side of the guide cover 300 along the thickness direction, and the connecting device is embedded in the fixing groove 311.

[0071] The fixing slot 311 can be an open snap-fit ​​structure set on one side of the guide cover 300 in the thickness direction. Specifically, it can be implemented by a U-shaped slot or a C-shaped slot structure, and its opening direction is perpendicular to the mounting plane of the guide cover 300.

[0072] It is understandable that the connecting device is embedded in the fixed slot 311, that is, the connecting part of the output flange 212 and the connecting flange 221 is embedded in the fixed slot 311, and the limiting is achieved by the side wall of the fixed slot 311. Then, the output flange 212 and the connecting flange 221 can be connected and fixed by bolts or the like.

[0073] Specifically, the opening direction of the fixing groove 311 of the guide cover 300 is consistent with the thickness direction of the guide cover 300. During installation, the connecting device between the output flange 212 and the connecting flange 221 can be directly embedded into the fixing groove 311 along the thickness direction. The side wall of the fixing groove 311 can form a wrapping limit for the connecting device, preventing the connecting device from shifting in the horizontal direction. During the lifting and lowering of the sewage discharge assembly 200, the fitting structure between the fixing groove 311 and the connecting device can maintain the stability of the connecting device and prevent the flange connection from loosening due to vibration.

[0074] Thus, the open structure of the fixing slot 311 allows the connecting device to be directly embedded into the fixing slot 311 for positioning. Then, the connection can be achieved simply by connecting and fixing the output flange 212 to the connecting flange 221 with bolts, eliminating the need for repeated flange position adjustments. This enables rapid positioning and installation of the sewage pump 210 and the connecting pipe 220, reducing the manual operation difficulty of flange connection. Furthermore, the mechanical limiting function of the fixing slot 311 ensures the stability of the connecting device during lifting and lowering, avoiding the risk of seal failure and improving the reliability of underwater installation operations.

[0075] In some embodiments, combined with Figure 1 and Figure 2 The fixed slot 311 may be provided with a positioning protrusion 312, which divides the fixed slot 311 into a first slot for accommodating the output flange 212 and a second slot for accommodating the connecting flange 221. The connecting flange 221 is configured to fit against the output flange 212 when it is located in the second slot.

[0076] Understandably, when the guide cover 300 is fixed to the sewage pump 210, the output flange 212 can be snapped into the first groove to temporarily limit the guide cover 300 and the sewage pump 210. Then, the guide cover 300 and the sewage pump 210 are connected by welding or other means. When the sewage pump 210 is connected to the connecting pipe 220, the connecting flange 221 is snapped into the second groove. At this time, the output flange 212, the positioning protrusion 312 and the guide rod together temporarily limit the connecting pipe 220. Then, the output flange 212 and the connecting flange 221 are connected by bolts or other means to fix the sewage pump 210 and the connecting pipe 220.

[0077] Optionally, the output flange 212 and the connecting flange 221 may be provided with clearance openings to accommodate the positioning protrusion 312, so that the positioning protrusion 312 exists at the connection between the output flange 212 and the connecting flange 221.

[0078] As can be seen, the positioning protrusion 312 provides positioning space for both the output flange 212 and the connecting flange 221, and also ensures that the two can be accurately aligned during assembly, improving the stability and reliability of the connection. The design of the positioning protrusion 312 also simplifies the assembly process, enabling installers to complete the assembly of the sewage discharge assembly 200 more quickly and accurately, thus improving work efficiency.

[0079] In some embodiments, combined with Figure 1 and Figure 2 The guide portion 320 is formed as a guide groove 321. The guide portion 320 is provided on the edge of the guide cover 300 along its own width direction, and the guide rod 100 is fitted into the guide groove 321.

[0080] The guide groove 321 can be a groove structure set along the edge of the guide cover 300 in the width direction. Specifically, it can be realized by a U-shaped or C-shaped cross-section groove. Its inner wall forms a sliding contact surface with the surface of the guide rod 100 to restrict the degree of freedom of the guide cover 300 along the axial direction of the guide rod 100.

[0081] The guide rod 100 can be a rod-shaped component fixed to the mounting surface. Specifically, it can be made of round steel or square steel. Its axial direction is consistent with the lifting direction of the guide cover 300. It forms a sliding pair with the guide groove 321 to realize the guiding function.

[0082] Specifically, the guide grooves 321 on both sides of the guide cover 300 form a sliding fit with the two parallel guide rods 100 respectively. When the sewage discharge component 200 is subjected to external force, the inner wall of the guide groove 321 contacts the surface of the guide rod 100 to generate sliding friction, causing the guide cover 300 to move along the axis of the guide rod 100.

[0083] As can be seen, through the sliding fit structure between the guide groove 321 and the guide rod 100, the sewage discharge component 200 can automatically achieve axial alignment during the lifting process without relying on manual underwater adjustment. The sewage discharge component 200 always maintains the predetermined trajectory during the lifting process, avoiding sealing failure due to deviation, and reducing the underwater operation intensity of the operator.

[0084] In some embodiments, combined with Figure 1 and Figure 2 There are two guide rods 100, which are arranged at intervals along the width direction of the guide cover 300. There are two guide parts 320 corresponding to the guide rods 100, and the two guide parts 320 are respectively provided on both sides of the guide cover 300 along its own width direction.

[0085] The guide rod 100 can be a rod-shaped structure fixed on the mounting surface, and can be made of metal, such as stainless steel or carbon steel, to provide a guide path for the lifting and lowering movement of the sewage discharge component 200.

[0086] By arranging two guide rods 100 at intervals along the width direction, a symmetrical support structure can be formed, enhancing stability during lifting. The guide portion 320 can be a guide groove 321 that slides with the guide rod 100, used to accommodate the guide rod 100 and limit the lateral displacement of the sewage discharge assembly 200.

[0087] By setting the two guide portions 320 on the two sides of the guide cover 300 in the width direction, the contact surfaces of the guide rod 100 and the guide groove 321 can be distributed on both sides, avoiding tilting or jamming caused by force on one side.

[0088] Specifically, the two guide rods 100 are fixed parallel to each other on the mounting surface. In actual design, their spacing can be adjusted according to the width of the guide cover 300. The guide parts 320 on both sides of the guide cover 300 slide with the corresponding guide rods 100 respectively. When the sewage discharge assembly 200 moves up and down along the guide rods 100, the guide grooves 321 on both sides simultaneously constrain the movement trajectory of the guide rods 100, so that the sewage pump 210 and the flange of the connecting pipe 220 always remain aligned.

[0089] The symmetrical layout design of the double guide rods 100 and the double guide sections 320 makes the force more even during the lifting process. Even if there is external disturbance or uneven weight distribution of the connecting pipe 220, it can effectively avoid deviation or tilting.

[0090] As can be seen, the symmetrical arrangement of the double guide rods 100 and the double guide sections 320 enables stable lifting and lowering without manual intervention, improving the efficiency and accuracy of flange docking. It also solves the problem of misalignment that may occur when installing the traditional sewage pump 210 due to unilateral guidance. The symmetrically distributed guide rods 100 and guide grooves 321 ensure that the flanges of the sewage pump 210 and the connecting pipe 220 are automatically aligned during lifting and lowering, reducing the number of manual adjustments and lowering the risk of leakage due to poor sealing.

[0091] In some embodiments, combined with Figure 1 and Figure 2 The guide cover 300 is also equipped with a lifting structure 330. The pressurized sewage system also includes a lifting component 400, which is connected to the lifting structure 330. The lifting component 400 is communicatively connected to the lifting device for lifting or lowering the sewage component 200.

[0092] The hoisting structure 330 can be a load-bearing connection component set on the guide cover 300. Specifically, it can be implemented by welding or bolting a lifting ring or hook, which provides a reliable force support point for the hoisting component 400.

[0093] The lifting component 400 can be a flexible or rigid connecting component used to transmit lifting force. Specifically, it can be a chain, wire rope or hydraulic rod with a hook. Its function is to achieve the vertical displacement of the sewage discharge component 200 by cooperating with the lifting structure 330.

[0094] Specifically, the lifting structure 330 can be fixed to the top of the guide cover 300 by welding or bolting, and the connecting end of the lifting component 400 is detachably connected to the lifting structure 330. When maintenance or replacement of the sewage discharge component 200 is required, the lifting component 400 drives the lifting structure 330 through an external power source, causing the sewage discharge component 200 connected to the guide cover 300 to move up and down along the guide rod 100. The sliding fit structure between the guide cover 300 and the guide rod 100 ensures that the sewage discharge component 200 remains vertically stable during lifting and lowering, avoiding misalignment that could lead to sealing failure of the connection device.

[0095] As can be seen, through the coordinated action of the hoisting structure 330 and the guide rod 100, the sewage discharge component 200 can be lifted and lowered as a whole, avoiding the secondary displacement of the sealing surface caused by the traditional split installation, ensuring that the connecting device always maintains the preset alignment state during the lifting process, and ensuring the operational stability of the pressurized sewage discharge system.

[0096] In some embodiments, combined with Figure 1 and Figure 2 The pressurized sewage system includes a lifting device, which is connected to the lifting component 400 to drive the sewage component 200 to move up and down.

[0097] Specifically, the control device is connected to the lifting device. Based on the detection results of the pressure detection device 600, the control device sends instructions to drive the sewage discharge component 200 to be lifted or lowered.

[0098] The lifting device can be a drive mechanism that can generate linear motion to move other components. Specifically, it can be implemented by electric push rod, hydraulic cylinder or winch, and the lifting action is achieved through power output.

[0099] Specifically, the lifting device generates driving force through a power source, which is transmitted to the sewage discharge assembly 200 via the lifting component 400, causing it to rise or fall along the guide rod 100. During installation or maintenance, the height of the sewage discharge assembly 200 can be adjusted by controlling the operation of the lifting device.

[0100] The automatic lifting and lowering of the sewage discharge assembly 200 is achieved through the cooperation of the pressure detection device 600, the control device, and the lifting device. This allows the sewage discharge assembly 200 to adjust its height according to the actual sewage depth or debris accumulation, enabling it to adapt to sewage extraction at different heights and ensuring the versatility and applicability of the sewage discharge assembly 200.

[0101] In some embodiments, combined with Figure 1 and Figure 2There are at least two sewage pumps 210, including a first sewage pump 2101 and a second sewage pump 2102. The output port of the first sewage pump 2101 is connected to the input port 211 of the second sewage pump 2102 through a connecting pipe 220. The output port of the second sewage pump 2102 is connected to an external connecting pipe through a connecting pipe 220. There are two guide covers 300. One guide cover 300 is connected to the connecting device at the output port of the first sewage pump 2101 and slides with the guide rod 100. The other guide cover 300 is connected to the connecting device at the output port of the second sewage pump 2102 and slides with the guide rod 100.

[0102] Among them, at least two sewage pumps 210 can be arranged in series with a pump body structure. Specifically, the first sewage pump 2101 and the second sewage pump 2102 can be connected in a front-to-back manner, and the output port of the first pump is connected to the input port 211 of the second pump through a connecting pipe 220.

[0103] It is understandable that the second sewage pump 2102 can be connected to external devices through external connection pipes to realize sewage transportation, treatment and discharge operations.

[0104] Optionally, the external device can be a sewage conveying and storage device, such as sewage pipes, sewage pools or sump pits, water storage tanks or water tanks, etc.; it can also be a sewage treatment device, such as sewage treatment equipment, oil-water separators, etc.; or it can be a reuse device, such as irrigation systems, fire pools, etc.

[0105] Optionally, the external connection pipe can also be extended to natural water bodies, such as rivers, lakes, and oceans, to facilitate sewage discharge.

[0106] There are two guide covers 300, meaning that each sewage pump 210 has an independent guide structure at its output port. Specifically, two guide covers 300 can be fixed to two connecting devices respectively. The sliding fit of the guide covers 300 can synchronously control the lifting and lowering trajectories of the two sewage pumps 210.

[0107] The connecting device is embedded in the fixed slot 311, that is, the slot structure realizes the quick positioning of the connecting flange 221 and the output flange 212. Specifically, a U-shaped slot or annular slot can be used to embed the flange edge into it.

[0108] Specifically, the first sewage pump 2101 and the second sewage pump 2102 form a series structure through the connecting pipe 220. The output flange 212 of the first sewage pump 2101 and the input flange of the second sewage pump 2102 are connected through the connecting pipe 220. Two guide covers 300 are respectively fixed on the output port connection device of the first sewage pump 2101 and the second sewage pump 2102. The guide part 320 of the guide cover 300 slides with the guide rod 100, so that the two sewage pumps 210 maintain synchronous vertical movement during the lifting and lowering process.

[0109] When installation or disassembly is required, the guide cover 300 is driven to move along the guide rod 100 by the lifting device, which drives the two sewage pumps 210 to rise or fall simultaneously, ensuring that the connecting pipe 220 and the external connecting pipe are always in a coaxial alignment state.

[0110] Traditional sewage systems typically only have one sewage pump 210. In this application, the sewage discharge efficiency is improved by designing a pump body structure with at least two pumps connected in series. In addition, through the design of the series pump body structure and two guide covers 300, the lifting trajectory of multiple sewage pumps 210 is uniformly controlled by the guide rod 100, and the synchronous lifting of multiple sewage pumps 210 can be achieved without manual intervention, ensuring stability during the lifting process.

[0111] In some embodiments, combined with Figure 1 and Figure 2 The booster sewage system also includes a connecting frame 500, which is fixedly connected to two sewage pumps 210 respectively.

[0112] The connecting frame 500 can be a rigid structural component used to connect two sewage pumps 210. Specifically, it can be implemented by a welded metal profile frame or a high-strength plastic integral molding structure. Its two ends can be fixedly connected to the housings of the two sewage pumps 210 by bolt fastening or snap locking, so as to limit the relative displacement between the two sewage pumps 210 and avoid the sewage pumps 210 from being misaligned due to vibration or water flow impact.

[0113] Specifically, the connecting frame 500 is designed to span the installation area between the two sewage pumps 210. When the two sewage pumps 210 are raised and lowered along the guide rod 100, the connecting frame 500 maintains a constant distance between them, ensuring that the flange between the output port and the connecting pipe 220 is always in the same axial direction. This rigid connection method allows the two pump bodies to move synchronously during the raising and lowering process. By integrating multiple sewage pumps 210 into a unified motion unit through the connecting frame 500, the relative positional relationship is automatically maintained during the raising and lowering process, reducing the frequency of manual intervention.

[0114] In some embodiments, combined with Figure 1 and Figure 2The connecting pipe 220 is provided with an openable and closable drain port 222, which is used to open and drain sewage when the pressure in the connecting pipe 220 is greater than the preset pressure value.

[0115] The closable drain outlet 222 can be a controllable opening and closing structure installed on the side wall of the connecting pipe 220. Specifically, it can be implemented by a solenoid valve, pneumatic valve, manual valve, etc. It can achieve rapid opening and closing by receiving control signals, or the drain outlet 222 can be manually opened when sewage needs to be discharged.

[0116] Optional, combined Figure 4 The connecting pipe 220 is equipped with a dirt-blocking net 223, and the drain outlet 222 is located between the dirt-blocking net 223 and the water inlet of the connecting pipe 220. In this way, the dirt-blocking net 223 can intercept dirt, and the dirt can be discharged from the connecting pipe 220 by opening the drain outlet 222.

[0117] Specifically, in one example, during the operation of the pressurized sewage system, the pressure detection device 600 continuously collects pressure data within the connecting pipe 220. When the detected pressure exceeds a preset pressure value, the drain port 222 is opened, allowing debris blocking the pipe to be discharged from the drain port 222, thereby reducing the internal pressure. After the pressure drops back to a safe range, the drain port 222 closes, and sewage discharge continues.

[0118] In some specific embodiments, the pressure detection device 600 can be installed in the middle of the connecting pipe 220 to accurately reflect the fluid pressure status, and the drain port 222 can be set at the bottom of the connecting pipe 220 to facilitate the rapid discharge of debris.

[0119] Optionally, the pressure detection device 600 can also be connected to the lifting device. When the pressure exceeds the preset pressure value, the lifting device drives the sewage discharge component 200 to rise. After the sewage discharge component 200 rises, the distance between the sewage pump 210 and the mounting surface increases, preventing debris from accumulating at the outlet.

[0120] By designing a pressure detection device 600 and providing a drain port 222 on the connecting pipe 220, the dirt inside the connecting pipe 220 can be quickly cleaned when the pressure is abnormal, thereby releasing pressure, maintaining the pressure of the connecting pipe 220 within a safe range, ensuring the operating efficiency of the drain assembly 200, reducing maintenance costs, and extending the service life of the equipment.

[0121] In some embodiments, combined with Figure 1 and Figure 2 The pressurized sewage system may also include a control device, which is electrically connected to the pressure detection device 600. The control device can control the opening and closing of the sewage outlet 222 and / or control the lifting device based on the detection results of the pressure detection device 600.

[0122] The control device can be an electronic device used to receive pressure detection signals and generate control commands. Its function is to automatically trigger the opening or closing of the drain outlet 222 according to the preset pressure threshold. In addition, it can also control the lifting device to adjust the height position of the drain component 200.

[0123] The opening and closing of the sewage outlet 222 can be controlled by mechanical or electric actuators to open or close the connecting pipe 220. Specifically, solenoid valves, electric butterfly valves, etc. can be used.

[0124] Specifically, the pressure detection device 600 collects pressure data in the connecting pipe 220 in real time and transmits it to the control device. When the pressure exceeds the preset value, the control device sends an opening command to the actuator of the drain port 222. The drain port 222 opens, and the sewage is discharged from the drain port 222 manually or by flushing with water, so that the pressure in the connecting pipe 220 is released quickly.

[0125] In addition, the control device can also link the lifting device to drive the sewage discharge component 200 to adjust its height along the guide rod 100. When the pressure exceeds the preset pressure value, the lifting device drives the sewage discharge component 200 to rise. After the sewage discharge component 200 rises, the distance between the sewage pump 210 and the mounting surface increases, preventing debris from accumulating at the outlet.

[0126] Thus, through automated pressure monitoring and control of the drain outlet 222 and / or lifting device, pressure can be automatically released when the pressure in the connecting pipe 220 is abnormal, preventing leakage or equipment damage caused by excessive pressure, and ensuring the sewage discharge efficiency and service life of the booster sewage system.
