Description

Technical Field

[0001] This invention relates to the technical field of integrated pump gate systems and their control methods, specifically to a horizontal-lifting integrated pump gate system and its lifting speed adjustment method. Background Technology

[0002] The integrated pump gate combines a submersible pump with the gate body, making the gate and pump body one unit. This design is simple in structure and easy to operate. The submersible pump and gate body are integrated into a single unit, enabling the gate body to block water and prevent backflow from external rivers, while the pump body can pump water from lower elevations to higher elevations for forced drainage. This not only fulfills flood control and drainage functions but also addresses the needs of ecological water replenishment.

[0003] The existing integrated pump gate structure is in a vertically closed state when the gate is at the bottom and in a horizontally open state when it is at the top. To achieve stable opening and closing of the gate, the lifting and lowering of the gate is often set to a uniform speed. However, since the stress conditions of the gate are different at different positions during different working processes, the preset initial lifting and lowering speed may not meet the stress requirements of each working process. This can easily damage the gate itself, its upper wheel and lifting lugs, and also pose a safety hazard to the pump and steel cable, thus affecting the normal opening and closing of the integrated pump gate. Therefore, it is necessary to adjust the preset initial lifting and lowering speed accordingly to ensure the stability, safety and rationality of the lifting and lowering process.

[0004] On the one hand, existing simulation technology cannot fully restore the pump gate structure (for example, the model will be simplified accordingly to simplify the mesh and the number of nodes). On the other hand, simulation technology cannot fully simulate the current working scenario of the integrated pump gate structure and the structural changes and lifting speed changes that may occur due to wear and tear caused by the years of use. Therefore, relying solely on software simulation technology to adjust the preset initial lifting speed of the integrated pump gate is not very reliable.

[0005] On the other hand, simply relying on the actual working process to adjust the preset initial lifting speed of the integrated pump gate lacks corresponding guidance and direction. It may be necessary to perform multiple adjustment processes to determine the actual lifting speed after adjustment, resulting in low adjustment efficiency.

[0006] Therefore, a new solution is needed to address the defects and shortcomings of the existing technology. Summary of the Invention To address the shortcomings and deficiencies in existing technologies, this invention provides an integrated lifting and horizontal pump gate system and its lifting speed adjustment method.

[0007] The specific solution provided by this invention is as follows: A type of integrated pump gate system includes a track fixed between an inland waterway and an outer waterway. An integrated pump gate capable of being raised, lowered, and rotated relative to the track is installed inside the track. A power source is fixed at the top of the track, and the output end of the power source is connected to the integrated pump gate via a steel cable to drive the integrated pump gate to move relative to the track. The track includes a vertical track fixedly installed on the side near the outer river channel and a curved track fixedly installed on the side near the inner river channel. The integrated pump gate is located between the vertical track and the curved track. The curved track includes a straight track, a connecting track and an inclined track fixedly connected from bottom to top. The distance between the top of the inclined track and the vertical track is greater than the distance between the bottom of the inclined track and the vertical track. The integrated pump gate is equipped with several submersible pumps inside the gate body. The inlet of the submersible pump faces the inner river channel, and the outlet of the submersible pump faces the outer river channel. The side of the gate body facing the outer river channel has a protruding lifting lug that is fixedly connected to the steel cable. The two sides of the gate body and the side facing the inner river channel are respectively equipped with a main wheel and a secondary wheel that can rotate relative to the inner wall of the curved track. Its features are: A control unit is also provided at the top of the track. The control unit can send corresponding control commands to the power source according to the simulated and actual motion of the integrated pump gate, so as to adjust the lifting speed of the integrated pump gate.

[0008] As a further preferred embodiment of the present invention, a gate locking part is fixed on the side of the gate body facing the outer river channel, and a track locking part is fixed on the top of the track, and the gate locking part and the track locking part are locked together accordingly.

[0009] As a further preferred embodiment of the present invention, an external river maintenance gate capable of being raised and lowered is provided on the side closer to the external river channel, and an internal river maintenance gate capable of being raised and lowered is provided on the side closer to the internal river channel.

[0010] As a further preferred embodiment of the present invention, the integrated pump gate is equipped with several force sensors, which are at least located on the outer edge of the gate body, the lifting lugs, the main wheel and the auxiliary wheel, and the submersible pump position.

[0011] As a further preferred embodiment of the present invention, the control unit issues corresponding control commands according to the following formula to adjust the lifting speed of the integrated pump gate: V = V0 + △V1 + △V2 in, V represents the actual lifting and lowering speed of the integrated pump gate after adjustment; V0 represents the initial lifting and lowering speed of the integrated pump gate; △V1 represents the adjustment speed of the integrated pump gate determined according to the actual motion conditions; △V2 represents the adjustment speed of the integrated pump gate determined based on the simulated motion conditions; △V1 and △V2 take negative values ​​opposite to the direction of motion of V0, and satisfy |△V1| is greater than |△V2|.

[0012] As a further preferred embodiment of the present invention, during the preset working process... When the real-time force values ​​detected by the sensor do not exceed the preset actual safety threshold, △V1=0; When any of the real-time force values ​​detected by the sensor reaches the preset actual safety threshold, △V1=-V1.

[0013] As a further preferred embodiment of the present invention, during the preset working process... When the simulated force values ​​obtained during the simulation do not exceed the preset simulation safety threshold, △V2=0; When any of the simulated force values ​​obtained during the simulation reaches the preset simulation safety threshold, ΔV2 = -V2; Furthermore, the preset actual safety threshold is greater than the preset simulated safety threshold.

[0014] As a further preferred embodiment of the present invention, the preset working process includes: 1) When the integrated pump gate is vertically positioned at the low position; 2) When the integrated pump gate is located at a corner position; 3) When the integrated pump gate is in a high position.

[0015] As a further preferred embodiment of the present invention, the preset working process further includes: 1.1) When the integrated pump gate is vertically in the low position and the submersible pump is not turned on; 1.2) When the integrated pump gate is vertically in the low position and the submersible pump is turned on.

[0016] Furthermore, the present invention also provides a method for adjusting the lifting speed of an integrated lifting and horizontal pump gate system, characterized by comprising the following steps: S1: Determine the initial lifting speed V0 of the integrated pump gate based on the working requirements and the output power of the power source; S2: Based on work requirements and pump gate parameters, predetermine and set the preset actual safety threshold and preset simulated safety threshold for the outer edge of the gate body, lifting lugs, main wheel and auxiliary wheel, and the submersible pump position; S3: Simulate the working process of the integrated pump gate, and in the preset working process, determine whether the simulated force value obtained in the simulation process exceeds the preset simulated safety threshold, and determine the adjustment speed △V2 of the integrated pump gate according to the simulated motion. S4: Detect the working process of the integrated pump gate, and in the preset working process, determine whether the real-time force value detected by the sensor exceeds the preset actual safety threshold, and determine the adjustment speed △V1 of the integrated pump gate according to the actual motion condition. S5: Adjust the initial lifting speed of the integrated pump gate by adjusting the speed △V2 of the integrated pump gate determined according to the simulated motion conditions in step S3 and adjusting the speed △V1 of the integrated pump gate determined according to the actual motion conditions in step S4, so as to obtain the actual lifting speed V of the integrated pump gate after adjustment. S6: The control unit sends a corresponding control command to the power source to adjust the lifting speed of the integrated pump gate from the initial lifting speed V0 to the actual lifting speed V.

[0017] Compared with existing technologies, the technical effects that this invention can achieve include: 1) This invention provides a lifting and horizontal integrated pump gate system and its lifting speed adjustment method. By setting a control unit, it can send corresponding control commands to the power source according to the simulated motion state and the actual motion state of the integrated pump gate, so as to adjust the lifting speed of the integrated pump gate. In this way, it can take into account both the simulated motion state and the actual motion state of the integrated pump gate, and effectively improve the adjustment efficiency of the preset initial lifting speed of the integrated pump gate while ensuring the reliability of the adjustment of the preset initial lifting speed of the integrated pump gate.

[0018] 2) This invention provides a lifting-horizontal integrated pump gate system and its lifting speed adjustment method. The system uses the following settings: V = V0 + △V1 + △V2; where V represents the actual lifting speed of the integrated pump gate after adjustment; V0 represents the initial lifting speed of the integrated pump gate; △V1 represents the adjustment speed of the integrated pump gate determined based on the actual motion conditions; △V2 represents the adjustment speed of the integrated pump gate determined based on the simulated motion conditions; △V1 and △V2 are negative values ​​opposite to V0, and |△V1| is greater than |△V2|. Since the simulation process simplifies the model for ease of calculation, it cannot completely restore the pump gate structure. Simulation technology also cannot completely simulate the current working scenario of the integrated pump gate structure, nor the structural changes and lifting speed changes caused by wear due to years of use. Therefore, |△V1| is set to be greater than |△V2| to ensure the reliability of the preset initial lifting speed adjustment of the integrated pump gate through a larger numerical influence.

[0019] 3) This invention provides a horizontally integrated pump gate system and its lifting speed adjustment method. By setting a preset working process, it determines whether the simulated force value obtained by the integrated pump gate during the simulation exceeds a preset simulated safety threshold. Based on the simulated motion, it determines the adjustment speed ΔV2 of the integrated pump gate. It also determines whether the real-time force value detected by the sensor exceeds a preset actual safety threshold. Based on the actual motion, it determines the adjustment speed ΔV1 of the integrated pump gate. Specifically, the preset working process includes: 1) when the integrated pump gate is vertically in a low position; 2) when the integrated pump gate is in a corner position; and 3) when the integrated pump gate is horizontally in a high position. By selecting the above three extreme preset working processes, it ensures that the force condition of the corresponding preset working process is also the extreme value of the integrated pump gate structure in the overall working process. Therefore, by judging the above three extreme preset working processes, the safety and reliability of the entire integrated pump gate structure in the overall operation process can be verified, simplifying the judgment process while ensuring the accuracy of the judgment.

[0020] 4) This invention provides a horizontally adjustable integrated pump gate system and its lifting speed adjustment method. By setting a preset working process including 1.1) when the integrated pump gate is vertically in a low position and the submersible pump is not turned on; and 1.2) when the integrated pump gate is vertically in a low position and the submersible pump is turned on, the system takes into account the stress condition of the submersible pump when it is turned on and off while the integrated pump gate is vertically in a low position. This further ensures the comprehensiveness and reliability of the stress condition judgment of the integrated pump gate structure, thereby improving the accuracy and efficiency of the preset initial lifting speed adjustment of the integrated pump gate.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] In the description of this invention, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] [First embodiment] like Figure 1-5The diagram shows a lifting and lowering integrated pump gate system provided in the first embodiment of the present invention, including a track 1 fixed between an inland waterway and an outer waterway. An integrated pump gate 2 capable of lifting, lowering, and rotating relative to the track 1 is arranged inside the track 1. A power source 3 is fixed at the top of the track 1. The output end of the power source 3 is connected to the integrated pump gate 2 via a steel cable 4 to drive the integrated pump gate 2 to move relative to the track 1. Correspondingly, a lifting lug 23 fixedly connected to the steel cable 4 is provided on the side of the gate body 21 facing the outer waterway. In this embodiment, the power source 3 can be a combination of a drive motor and a winch. The output power of the drive motor drives the winch to move, thereby driving the integrated pump gate 2 to lift and lower relative to the track 1 inside the track 1 by winding and unwinding the steel cable 4. For example, when the water level of the outer river is higher than that of the inner river, the integrated pump gate 2 is in the low position P1 and closed to achieve the function of blocking water and preventing the water from the outer river from entering the inner river and causing backflow of the outer river; while when the water level of the inner river is higher than that of the outer river, the integrated pump gate 2 is raised to the high position P3 and opened to discharge the water from the inner river into the outer river.

[0031] The track 1 includes a vertical track 11 fixedly installed on the side near the outer river channel and a curved track 12 fixedly installed on the side near the inner river channel. The integrated pump gate 2 is located between the vertical track 11 and the curved track 12. The curved track 12 includes a straight track 121, a connecting track 122 and an inclined track 123 fixedly connected from bottom to top. The distance between the top of the inclined track 123 and the vertical track 11 is greater than the distance between the bottom of the inclined track 123 and the vertical track 11. By setting the track 1, the integrated pump gate 2 inside can realize the lifting and lowering process according to the route set by the track 1. Correspondingly, the two sides of the gate body 21 and the side facing the inner river channel are respectively rotatably equipped with main wheels 24 and auxiliary wheels 25 that can rotate relative to the inner wall of the curved track 12. The main wheels 24 and auxiliary wheels 25 set at different positions of the gate body 21 can achieve rolling contact with the inner wall of the curved track 12 in different directions. While realizing rolling contact to reduce frictional resistance, it can also help to realize the limiting effect of the integrated pump gate 2 inside the track 1.

[0032] The integrated pump gate 2 has several submersible pumps 22 installed inside the gate body 21. The inlet of the submersible pump faces the inner river channel, and the outlet of the submersible pump faces the outer river channel. When the water level of the inner river channel reaches the preset height, the submersible pump 22 is started, which can draw water from the inner river channel through the inlet of the submersible pump and then discharge it through the outlet of the submersible pump, thereby achieving a strong discharge effect on the water in the inner river channel.

[0033] To ensure the stable positioning of the integrated pump gate 2 at the high position P3, a gate body locking part 26 is fixed to the side of the gate body 21 facing the outer river channel, and a track locking part 6 is fixed to the top of the track 1. The gate body locking part 26 and the track locking part 6 are locked together. Through the locking cooperation between the gate body locking part 26 and the track locking part 6, the integrated pump gate 2 can be locked at the high position P3, ensuring its stability at the current position. The gate body locking part 26 and the track locking part 6 can be selected with corresponding locking structures according to actual locking needs. For example, a locking structure in which a latch that can be opened and closed cooperates with a locking ring of a fixed structure can be selected (the latch opens to expose a notch and enters the lock ring, and then closes the latch to close the notch). Alternatively, a locking structure in which a latch that can be rotated and locked in position cooperates with a locking ring of a fixed structure can be selected (the latch enters the lock ring, rotates, and locks).

[0034] In order to enable regular cleaning, maintenance and locking of track 1 and integrated pump gate 2, an outer river maintenance gate 71 that can be raised and lowered is set on the side near the outer river channel, and an inner river maintenance gate 72 that can be raised and lowered is set on the side near the inner river channel. Before maintenance, the outer river maintenance gate 71 and the inner river maintenance gate 72 are lowered to ensure the safety and stability of the maintenance process.

[0035] The improvement of this embodiment compared to the prior art is as follows: A control unit 5 is also provided at the top of the track 1. The control unit 5 can send corresponding control commands to the power source 3 according to the simulated motion and actual motion of the integrated pump gate 2 to adjust the lifting speed of the integrated pump gate 2. This can take into account both the simulated motion and actual motion of the integrated pump gate, and effectively improve the adjustment efficiency of the preset initial lifting speed of the integrated pump gate while ensuring the reliability of the adjustment.

[0036] In order to realize the actual force condition during the actual movement of the integrated pump gate 2, several force sensors are installed on the integrated pump gate 2. The sensors are at least located at the outer edge of the gate body 21, the lifting lug 23, the main wheel 24 and the auxiliary wheel 25, and the submersible pump 22, so as to realize the force detection at the position where the force condition is the greatest during the operation of the integrated pump gate 2.

[0037] In this embodiment, the control unit 5 issues corresponding control commands according to the following formula to adjust the lifting speed of the integrated pump gate 2: V = V0 + △V1 + △V2 in, V represents the actual lifting and lowering speed of the integrated pump gate after adjustment; V0 represents the initial lifting and lowering speed of the integrated pump gate, which is determined based on operational requirements, such as water level and flow rate requirements, as well as the output power of the power source (which must be within a safe range below the maximum output power of the power source). △V1 represents the adjustment speed of the integrated pump gate determined according to the actual motion conditions; △V2 represents the adjustment speed of the integrated pump gate determined based on the simulated motion conditions; △V1 and △V2 take negative values ​​opposite to the direction of motion of V0, and satisfy |△V1| is greater than |△V2|.

[0038] Because the simulation process simplifies the model for ease of calculation, it cannot completely restore the pump gate structure. The simulation technology also cannot fully simulate the current working scenario of the integrated pump gate structure, as well as the structural changes and lifting speed changes that may occur due to wear and tear over the years. Therefore, |△V1| is set to be greater than |△V2| to ensure the reliability of the preset initial lifting speed adjustment of the integrated pump gate through a larger numerical influence.

[0039] During the pre-set work process When the real-time force values ​​detected by the sensor do not exceed the preset actual safety threshold, △V1=0; at this time, it means that the actual force at the position of maximum force in the actual movement of the integrated pump gate 2 is within the safe range. Therefore, according to the actual movement of the integrated pump gate 2, the initial lifting speed V0 of the integrated pump gate 2 can be adjusted without intervention. When any of the real-time force values ​​detected by the sensor reaches the preset actual safety threshold, ΔV1 = -V1. This indicates that the actual force at the maximum position of the integrated pump gate 2 in actual movement has exceeded the safe range. Therefore, according to the actual movement of the integrated pump gate 2, it is necessary to adjust the initial lifting speed V0 of the integrated pump gate 2 accordingly. At this time, ΔV1 = -V1, taking a negative value opposite to the direction of movement of the initial lifting speed V0, so as to reduce the lifting speed of the integrated pump gate 2 by reducing the output power of the power source 3, and at the same time reduce the force on the integrated pump gate 2 in actual movement.

[0040] During the pre-set work process When the simulated force values ​​obtained during the simulation do not exceed the preset simulation safety threshold, △V2=0; at this time, it means that the simulated force at the maximum position of the integrated pump gate 2 in the simulated motion is within the safe range. Therefore, according to the simulated motion of the integrated pump gate 2, the initial lifting speed V0 of the integrated pump gate 2 can be adjusted without intervention. When any of the simulated force values ​​obtained during the simulation reaches the preset simulation safety threshold, ΔV2 = -V2. This indicates that the actual force at the maximum position of the integrated pump gate 2 in the simulated motion has exceeded the safe range. Therefore, according to the simulated motion of the integrated pump gate 2, it is necessary to adjust the initial lifting speed V0 of the integrated pump gate 2 accordingly. At this time, ΔV2 = -V2, taking a negative value opposite to the direction of the initial lifting speed V0, so as to reduce the lifting speed of the integrated pump gate 2 by reducing the output power of the power source 3, and at the same time reduce the force on the integrated pump gate 2 in the actual motion process.

[0041] The preset actual safety threshold and preset simulated safety threshold can be determined based on work requirements, such as water level and flow rate requirements, as well as pump gate parameters, such as the safety stress threshold of the selected material. To further ensure the stability of the integrated pump gate 2 during operation, the preset actual safety threshold and preset simulated safety threshold should be set lower than the safety stress threshold of the selected material. Furthermore, due to the limitations of the simulation process, such as structural simplification and the inability to fully replicate actual environmental parameters and wear conditions, the preset simulated safety threshold needs to be set lower than the preset actual safety threshold to ensure the accuracy of the judgment results with a higher threshold requirement.

[0042] It is worth noting that even if the simulated force value of the integrated pump gate used in this embodiment exceeds the corresponding preset simulation safety threshold due to reasons such as structural and calculation simplification, its simulated force value should still be lower than the safety force threshold of the selected material, so as to ensure the safety and stability of the integrated pump gate 2 during operation.

[0043] It is worth noting that the values ​​of V1 and V2 in this embodiment can be initially determined based on empirical parameters (such as drainage demand, flow demand and water level height) and corrected based on subsequent adjustment processes, so as to improve the adjustment efficiency while ensuring the stability of the integrated pump gate 2 after speed adjustment.

[0044] For example, in this embodiment, the distance between the low position P1 and the high position P3 of the integrated pump gate 2 is 10m. The initial lifting speed V0 of the integrated pump gate 2 is usually set to 1m / min to ensure the stability of the lifting process. When the gate body 21 is made of Q235 material, its yield strength is 235MPa. In order to further ensure the stability of the integrated pump gate 2 during operation, the preset actual safety threshold can be set lower than the safety stress threshold of the selected material, such as 200MPa, while the preset simulated safety threshold can be set even lower, such as 150MPa. During the simulation, when the simulated stress value exceeds the corresponding preset simulated safety threshold of 150MPa, it is generally between 150-170MPa, which is still lower than the safety stress threshold of the selected material of 235MPa, so as to ensure the safety and stability of the integrated pump gate 2 during operation.

[0045] Based on this, V1 = 0.5 m / min and V2 = 0.2 m / min can be set according to empirical parameters. This setting will result in: When the real-time force value does not exceed the preset actual safety threshold and the simulated force value does not exceed the preset simulated safety threshold, the actual lifting speed V of the integrated pump gate after adjustment remains at the initial lifting speed, i.e., V=V0=1m / min. When the real-time force value does not exceed the preset actual safety threshold, but the simulated force value exceeds the preset simulated safety threshold, the actual lifting speed V of the integrated pump gate after adjustment satisfies: V=V0-V2=0.8m / min; When the real-time force value exceeds the preset actual safety threshold, but the simulated force value does not exceed the preset simulated safety threshold, the actual lifting speed V of the integrated pump gate after adjustment satisfies: V=V0-V1=0.5m / min; When the real-time force value exceeds the preset actual safety threshold and the simulated force value also exceeds the preset simulated safety threshold, the actual lifting speed V of the integrated pump gate after adjustment satisfies: V=V0-V1-V2=0.3m / min; V1 and V2 are negative values ​​opposite to the direction of the initial lifting speed V0. This reduces the lifting speed of the integrated pump gate 2 by reducing the output power of the power source 3, while also reducing the force on the integrated pump gate 2 during actual movement, thus maintaining stability during the lifting process.

[0046] The preset working process in this embodiment includes: 1) When the integrated pump gate is vertically in the low position P1; this includes 1.1) when the integrated pump gate is vertically in the low position P1 and the submersible pump 22 is not turned on; and 1.2) when the integrated pump gate is vertically in the low position P1 and the submersible pump 22 is turned on. This ensures that while the integrated pump gate is vertically in the low position, the stress condition of the submersible pump during opening and closing is also taken into account, so as to further ensure the comprehensiveness and reliability of the stress condition judgment of the integrated pump gate structure, thereby improving the accuracy and efficiency of the adjustment of the preset initial lifting speed of the integrated pump gate. 2) When the integrated pump gate is located at the corner position P2; 3) When the integrated pump gate is horizontally located at the high position P3.

[0047] By selecting the above three preset working processes of the limit, it is ensured that the stress state of the corresponding preset working process is also the extreme value of the integrated pump gate structure in the overall working process. Therefore, by judging the above three preset working processes of the limit, the safety and reliability of the entire integrated pump gate structure in the overall operation process can be verified, simplifying the judgment process while ensuring the accuracy of the judgment.

[0048] Preferably, since the integrated pump gate 2 operates differently at different positions on track 1, it moves vertically during the lifting stroke corresponding to the low position P1, moves vertically and rotates around the hinge point between the steel cable 4 and the lifting lug 23 during the lifting stroke corresponding to the middle position P2, and moves horizontally during the lifting stroke corresponding to the high position P3. Therefore, the force on the integrated pump gate 2 is also different under different operating conditions at different positions on track 1. To ensure the stability of the overall lifting process, the uniform lifting process can also be set as a lifting process with different speeds at different positions. For example, the initial lifting speed in the lifting stroke corresponding to the low position P1 can be set to VP10, and correspondingly, the initial lifting speeds in the lifting strokes corresponding to the middle position P2 and the high position P3 can be VP20 and VP30, respectively, and satisfying the following: VP20 < VP30 < VP10. Since the integrated pump gate 2 needs to be driven to move up and down and rotate simultaneously during the lifting stroke corresponding to the middle position P2, a low lifting speed is required to provide the most stable lifting process. Under the premise of a certain power, a lower lifting speed is also beneficial to output greater power to help the integrated pump gate 2 change from a vertical working posture to a horizontal working posture through rotation. However, after approaching the high position P3, in order to avoid unexpected collisions when in place and the locking failure of the integrated pump gate 2 due to the locking failure of the gate body locking part 26 and the track locking part 6, a lower lifting speed is required to ensure effective locking. Therefore, VP30 also needs to be set to a lower value. The lifting stroke corresponding to the low position P1 only involves the lifting process of the integrated pump gate 2, so its lifting speed can be set to the highest.

[0049] Based on this, the actual lifting speed can also be adjusted in the same way as in this embodiment for different initial lifting speeds within the lifting stroke corresponding to different working positions.

[0050] [Second embodiment] like Figure 6 As shown, the present invention also provides a method for adjusting the lifting speed of an integrated lifting and horizontal pump gate system mentioned in the first embodiment, comprising the following steps: S1: Determine the initial lifting speed V0 of the integrated pump gate based on the working requirements and the output power of the power source; S2: Based on work requirements and pump gate parameters, predetermine and set the preset actual safety threshold and preset simulated safety threshold for the outer edge of the gate body, lifting lugs, main wheel and auxiliary wheel, and the submersible pump position; S3: Simulate the working process of the integrated pump gate, and in the preset working process, determine whether the simulated force value obtained in the simulation process exceeds the preset simulated safety threshold, and determine the adjustment speed △V2 of the integrated pump gate according to the simulated motion. S4: Detect the working process of the integrated pump gate, and in the preset working process, determine whether the real-time force value detected by the sensor exceeds the preset actual safety threshold, and determine the adjustment speed △V1 of the integrated pump gate according to the actual motion condition. S5: Adjust the initial lifting speed of the integrated pump gate by adjusting the speed △V2 of the integrated pump gate determined according to the simulated motion conditions in step S3 and adjusting the speed △V1 of the integrated pump gate determined according to the actual motion conditions in step S4, so as to obtain the actual lifting speed V of the integrated pump gate after adjustment.
