When the workers leave, the exhaust fan will be turned off as the ventilation pipe group retracts, which also prevents the workers from forgetting to turn on the exhaust fan when they leave, thereby realizing the "open when entering and close when leaving" ventilation process of the rainwater pump station, saving electricity.

Description

Technical Field

[0001] The present invention relates to the technical field of municipal engineering, and in particular to an integrated rainwater pumping station with energy-saving exhaust. Background Art

[0002] A rainwater pumping station primarily refers to a pumping station installed in low-lying areas of a city or within a city's stormwater sewer system to drain rainwater. With the accelerating pace of urbanization in my country, the requirements for urban flood control are becoming increasingly stringent. As a crucial component of urban flood control systems, rainwater pumping stations play a key role in addressing urban waterlogging and have garnered considerable attention. The installation of rainwater pumping stations prevents urban waterlogging disasters, effectively improves the living environment of urban residents, and plays a significant role in enhancing a city's image.

[0003] Conventional rainwater pumping stations are easily clogged by pollutants and cannot pump water smoothly. As debris in the rainwater continues to accumulate in the pumping station pool, the rainwater in the pumping station pool becomes foul-smelling and pollutes the rainwater in the pumping station. When maintaining and inspecting the rainwater pumping station, workers are generally required to enter the pumping station. Before entering the pumping station, the interior of the pumping station needs to be ventilated and exhausted in advance. The ventilation and exhaust of conventional rainwater pumping stations are achieved through ventilation pipes or exhaust fans, which means that workers need to open the ventilation pipes or exhaust fans before entering the pumping station. Once the workers are negligent and rashly enter the pumping station, it is easy to cause the workers to suffer from hypoxia, carbon dioxide poisoning, etc. If the pumping station keeps the ventilation pipes or exhaust fans open, it will waste electricity and affect the service life of the equipment.

[0004] Therefore, there is an urgent need for an integrated rainwater pumping station with energy-saving exhaust. Summary of the Invention

[0005] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide an integrated rainwater pumping station with energy-saving and exhaust functions, comprising a pumping station body and a pump group installed in the pumping station body, an inlet pipe group connected to the pumping station body, and an outlet pipe group connected to the pump group.

The pipe-pushing rack is fixedly installed on the maintenance stand, and the pipe-pushing rack is connected to the water inlet grille assembly and the ventilation pipe group through a pull rope assembly. The upper end of the pipe-pushing rack is connected to the telescopic tube at the lower end of the ventilation pipe group.

[0006] To achieve the above objectives, the present invention adopts the following technical solutions: The present invention provides an integrated rainwater pumping station with energy-saving and exhaust functions. First, under normal conditions, the rainwater pumping station discharges rainwater from the inlet pipe assembly into the lower half of the pumping station body through the water inlet grille assembly for processing, filtration, and storage. When internal drainage is required, the pump assembly discharges rainwater from the pumping station body through the outlet pipe assembly. At this time, the ventilation pipe assembly is not fully extended, and the pipe opening of the uppermost telescopic pipe is exposed for natural ventilation. The second telescopic pipe from the top to the bottom is now located inside the third telescopic pipe, and the fourth telescopic pipe is located outside the third telescopic pipe.

[0007] When it is necessary to inspect the interior of the rainwater pump station, it is prevented that the maintenance workers forget to open the ventilation ducts and exhaust fans and enter the pump station body for inspection work without ventilation. In order to be able to quickly exhaust and ventilate the pump station body after the maintenance workers enter the pump station body, the maintenance workers' own weight is used to extend and open the ventilation pipe group and clean the water inlet grille assembly. After the maintenance workers enter the pump station body from the ladder inside the pump station body, when the maintenance workers stand on the maintenance platform, the maintenance platform slowly descends to the maintenance position. At the same time, the pipe-push frame on the maintenance platform moves downward with the maintenance platform and pushes the fourth telescopic tube, so that the fourth section of the telescopic tube extends downward, and at the same time drives the pull rope assembly to extend the first telescopic tube and the second telescopic tube upward, so that the first telescopic tube extends out of the top of the pump station body and turns on the exhaust fan.

[0008] Preferably, the upper ends of the second telescopic tube, the third telescopic tube and the fourth telescopic tube of the ventilation pipe group are all equipped with node rings, and the upper and lower adjacent telescopic tubes are slidably connected through the node rings, wherein the node ring on the third telescopic tube is fixedly connected to the top of the pump station body through a pipe rack, the pipe rack is fixedly installed on both sides of the ventilation pipe group, and the node rings on the second telescopic tube and the fourth telescopic tube are both slidably connected to the pipe rack, and the node ring on the second telescopic tube is connected to the pull rope assembly.

[0009] Preferably, a pipe shifting ring is installed on the fourth telescopic tube, and the pipe shifting ring is sleeved on the outer side of the fourth telescopic tube and connected to the pipe shifting frame.

[0010] Preferably, the water inlet grille assembly includes a main grille and a movable grille, the movable grille is slidably installed on the inner bottom of the main grille through a guide rod, the guide rod is fixedly installed on the inner bottom of the main grille, the movable grille is slidably connected to the guide rod, and the movable grille is connected to the pull rope assembly.

[0011] Preferably, the pull rope assembly includes two fixed pulleys and four pull ropes, the two fixed pulleys are respectively installed on the inner top of the pump station body and are located between the two pipe racks and the ventilation pipe group, one end of the two pull ropes are respectively connected to the pipe rack, and the other end passes around the corresponding fixed pulley and is connected to the node ring on the second telescopic tube, and the two ends of the other two pull ropes are respectively connected to the movable grid and the node ring on the second telescopic tube.

[0012] Preferably, an outer brush is installed at the lower end of the pipe rack, and the outer brush abuts against the outer side surface of the main grille.

[0013] Preferably, the lower surface of the node ring is evenly spaced along its circumference and mounted with a plurality of magnetic blocks, which can be magnetically connected to the node ring below.

[0014] Preferably, an elastic switch is installed on the lower side of the node ring on the fourth telescopic tube, and a pressure head is installed on the lower side of the node ring on the third telescopic tube. The pressure head can abut against the elastic switch, and the elastic switch is electrically connected to the exhaust fan.

[0015] Preferably, the elastic switch includes a switch seat and an elastic joint. The switch seat is fixedly mounted on the lower end of the node ring of the fourth telescopic tube. The elastic joint is mounted on the switch seat through two first springs. The two first springs are each mounted below the switch seat through a bolt. The bolts are vertically mounted at both ends of the switch. The two ends of the elastic joint are sleeved on the bolts. The two ends of the first spring respectively abut the lower ends of the elastic joint and the bolts. The lower end of the touch pressure head can pass through the switch seat and abut against the elastic joint. The switch seat is electrically connected to the exhaust fan, and the elastic joint is connected to an external power supply.

[0016] Preferably, the maintenance stand is connected to the bottom of the pump station body through a plurality of second springs, and both ends of all the second springs abut against the lower end of the maintenance stand and the bottom of the pump station body respectively.

[0017] The beneficial effect of the present invention is that when it is necessary to inspect the interior of the rainwater pump station, it prevents the inspection worker from forgetting to open the ventilation duct and the exhaust fan and entering the interior of the pump station body for inspection without ventilation. In order to be able to quickly exhaust and ventilate the pump station body after the inspection worker enters the pump station body, the inspection worker's own weight is used to extend and open the ventilation pipe group and clean the water inlet grille assembly. The main grille is automatically cleaned by the staggered movement of the outer brush and the movable grid plate in a one-up or one-up-one-down manner, and the rainwater is cleaned by the worker's own weight. Cleaning the water inlet grille assembly of the pump station greatly facilitates the workers' operation and saves their physical strength and time. By utilizing the workers' own weight, after the workers step onto the maintenance platform, the ventilation pipe group automatically extends and turns on the exhaust fan, and vice versa. There is no need for workers to actively turn on the exhaust fan, preventing them from forgetting to turn on the exhaust fan for ventilation. When the workers leave, the exhaust fan will be turned off as the ventilation pipe group retracts, which also prevents workers from forgetting to turn on the exhaust fan when they leave, realizing the "open when coming and close when leaving" ventilation process of the rainwater pump station, saving electricity.

DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Embodiment: The present invention provides an integrated rainwater pumping station with energy-saving exhaust, comprising a pumping station body 1 and a pump group 1a installed in the pumping station body 1, an inlet pipe group 1b connected to the pumping station body 1, and an outlet pipe group 1c connected to the pump group 1a, wherein the pump group 1a is installed on one side of the bottom of the pumping station body 1, the inlet pipe group 1b is installed in the middle of the pumping station body 1, the outlet pipe group 1c is installed in the upper half of the pumping station body 1 and one end thereof located inside the pumping station body 1 is connected to the pump group 1a pipeline, and further comprises: a ventilation pipe group 1d, an inlet grille assembly 1e and an inspection stand 1f, the ventilation pipe group 1d is vertically installed inside the pumping station body 1 and connected to the outside, and the ventilation pipe group 1d is a telescopic pipe structure composed of at least four sections of casing. Structure, which from top to bottom are respectively the first telescopic tube 1d0, the second telescopic tube 1d1, the third telescopic tube 1d2 and the fourth telescopic tube 1d3, the ventilation pipe group 1d is installed with an exhaust fan 1i, the water inlet grille assembly 1e is installed at the water inlet of the water inlet pipe group 1b, the maintenance stand 1f is movably installed inside the pump station body 1, the ventilation pipe group 1d is connected to the water inlet grille assembly 1e through the pull rope assembly 1g, the pull rope assembly 1g is connected to the maintenance stand 1f through the pipe-pushing rack 1d7, the pipe-pushing rack 1d7 is fixedly installed on the maintenance stand 1f, the pipe-pushing rack 1d7 is connected to the water inlet grille assembly 1e and the ventilation pipe group 1d through the pull rope assembly 1g, and the upper end of the pipe-pushing rack 1d7 is connected to the telescopic tube at the lowermost end of the ventilation pipe group 1d;

[0037] First, under normal conditions, the rainwater pumping station discharges rainwater from the inlet pipe assembly 1b into the lower half of the pumping station body 1, where it is processed, filtered, and stored through the inlet grille assembly 1e. When internal drainage is required, the pump assembly 1a discharges rainwater from the pumping station body 1 through the outlet pipe assembly 1c. At this time, the ventilation pipe assembly 1d is not fully extended, and the topmost telescopic pipe opening is exposed for natural ventilation. The second telescopic pipe 1d1, from top to bottom, is now located inside the third telescopic pipe 1d2, while the fourth telescopic pipe 1d3 is located outside the third telescopic pipe 1d2.

[0038] When it is necessary to inspect the interior of the rainwater pumping station, in order to prevent the maintenance workers from forgetting to open the ventilation ducts and exhaust fans 1i and entering the pumping station body 1 for maintenance work without ventilation, in order to be able to quickly exhaust and ventilate the pumping station body 1 after the maintenance workers enter the pumping station body 1, the maintenance workers' own weight is used to extend and open the ventilation pipe group 1d and clean the water inlet grille assembly 1e. After the maintenance workers enter the pumping station body 1 from the ladder 1h inside the pumping station body 1, when the maintenance workers stand on the maintenance platform 1f, the maintenance platform 1f slowly descends to the maintenance position, and at the same time, the pipe rack 1d7 on the maintenance platform 1f moves downward with the maintenance platform 1f and moves the fourth telescopic tube 1d3, so that the fourth telescopic tube 1d3 extends downward, and at the same time drives the pull rope assembly 1g to extend the first telescopic tube 1d0 and the second telescopic tube 1d1 upward, so that the first telescopic tube 1d0 extends out of the top of the pumping station body 1 and turns on the exhaust fan 1i.

[0039] The upper ends of the second telescopic tube 1d1, the third telescopic tube 1d2 and the fourth telescopic tube 1d3 of the ventilation pipe group 1d are all installed with node rings 1d4, and the upper and lower adjacent telescopic tubes are slidably connected through the node rings 1d4. The node ring 1d4 on the third telescopic tube 1d2 is fixedly connected to the top of the pump station body 1 through the pipe rack 1d5. The pipe rack 1d5 is fixedly installed on both sides of the ventilation pipe group 1d, and the node rings 1d4 on the second telescopic tube 1d1 and the fourth telescopic tube 1d3 are both slidably connected to the pipe rack 1d5. The node ring 1d4 on the second telescopic tube 1d1 is connected to the pull rope assembly 1g.

[0040] In order to achieve the extension and retraction of the ventilation pipe group 1d, the first telescopic tube 1d0 and the second telescopic tube 1d1 are connected by utilizing the cooperation of multiple groups of telescopic tubes and joint rings 1d4. The purpose is that the pull rope assembly 1g pulls the first telescopic tube 1d0 and the second telescopic tube 1d1 upward, and the joint ring 1d4 on the third telescopic tube 1d2 is used to fix the position of the ventilation pipe group 1d, so that the third telescopic tube 1d2 is always fixed on the pipe racks 1d5 on both sides to prevent the second telescopic tube 1d1 and the fourth telescopic tube 1d3 from being unstable during the retraction process. The joint rings 1d4 on the second telescopic tube 1d1 and the fourth telescopic tube 1d3 are slidably connected to the pipe rack 1d5 so that the second telescopic tube 1d1 and the fourth telescopic tube 1d3 will not be rotated and misaligned during retraction, and the stability of the ventilation pipe group 1d can be ensured.

[0041] The fourth telescopic tube 1d3 is fitted with a pipe-moving ring 1d6, which fits over the outside of the fourth telescopic tube 1d3 and is connected to a pipe-moving bracket 1d71h. Air holes 1d8 are provided on the walls of the fourth telescopic tube 1d3 and the first telescopic tube 1d0. When the pipe-moving bracket 1d71h drives the pipe-moving ring 1d6 and the fourth telescopic tube 1d3 downward, the fourth telescopic tube 1d3 extends, and the air holes 1d8 on the fourth telescopic tube 1d3 open, increasing the depth and area of air intake. Simultaneously, the first telescopic tube 1d0 extends upward to the exterior of the pump station body 1. The air vents on the first telescopic tube 1d0 also increase the area of the air outlet, enabling rapid ventilation and exhaust.

[0042] The water inlet grille assembly 1e includes a main grille 1e0 and a movable grille 1e1. The movable grille 1e1 is slidably mounted on the inner bottom of the main grille 1e0 through a guide rod 1e2. The guide rod 1e2 is fixedly mounted on the inner bottom of the main grille 1e0. The movable grille 1e1 is slidably connected to the guide rod 1e2. The movable grille 1e1 is connected to the pull rope assembly 1g.

[0043] In its natural state, the movable grating 1e1 has a certain degree of magnetism, and its initial position is at the bottom of the main grille 1e0. When the rainwater pumping station is being inspected, after the worker steps onto the inspection platform 1f, the inspection platform 1f slowly descends, and the pipe-moving rack 1d7 on the inspection platform 1f moves accordingly, while pulling the pull rope assembly 1g. The pull rope assembly 1g drives the movable grating 1e1 to move upward along the guide rod 1e2 in the main grille 1e0. The movable grating 1e1 rises and lifts the larger garbage or metal objects accumulated in the main grille 1e0 that enter the pumping station body 1 with rainwater to the outlet of the main grille 1e0, thereby facilitating the workers to clean it up.

[0044] The pull rope assembly 1g includes two fixed pulleys 1g0 and four pull ropes 1g1. The two fixed pulleys 1g0 are respectively installed on the inner top of the pump station body 1 and are located between the two pipe racks 1d5 and the ventilation pipe group 1d. One end of the two pull ropes 1g1 is respectively connected to the pipe rack 1d7, and the other end passes around the corresponding fixed pulley 1g0 and is connected to the node ring 1d4 on the second telescopic tube 1d1. The other two ends of the pull ropes 1g1 are respectively connected to the movable grid 1e1 and the node ring 1d4 on the second telescopic tube 1d1.

[0045] When the worker steps onto the maintenance platform 1f, the maintenance platform 1f drives the pipe-moving rack 1d7 to move downward, and the pipe-moving rack 1d7 drives the pipe-moving ring 1d6 and the fourth telescopic tube 1d3 to move downward, while pulling the two pull ropes 1g1 connected thereto, and then pulling the second telescopic tube 1d1 upward through the fixed pulley 1g0, and the other two pull ropes 1g1 will pull the movable grid 1e1 upward as well. At the same time, the second telescopic tube 1d1 lifts the first telescopic tube 1d0 and extends it out of the top of the pump station body 1 to enhance the ventilation effect; when the worker leaves the maintenance platform 1f, the maintenance platform 1f is reset, and due to the dead weight of the first telescopic tube 1d0 and the second telescopic tube 1d1 and the movable grid 1e1 and the connection and coordination with each other, their respective resets are also achieved.

[0046] An outer brush 1j is installed at the lower end of the pipe rack 1d7, and the outer brush 1j abuts against the outer side surface of the main grille 1e0.

[0047] Before the maintenance worker enters the pump station body 1, the maintenance stand 1f and the outer brush 1j are at the top plane of the main grille 1e0. When the pipe-pushing rack 1d7 moves downward with the maintenance stand 1f, the outer brush 1j on the pipe-pushing rack 1d7 will also move downward and clean the outside of the main grille 1e0. Some of the bristles of the outer brush 1j will pass through the grid holes of the main grille 1e0 due to elasticity to prevent the main grille 1e0 from being blocked. When the worker leaves the maintenance stand 1f, the maintenance stand 1f is reset, and the outer brush 1j will clean the main grille 1e0 in the opposite direction. Through the staggered movement of the outer brush 1j and the movable grating 1e1 up and down or up and down, the main grille 1e0 is automatically cleaned, and the water inlet grille assembly 1e of the rainwater pump station is cleaned by the worker's own weight, which greatly facilitates the worker's operation and saves the worker's physical strength and time.

[0048] The lower surface of each node ring 1d4 is evenly spaced and mounted with a number of magnetic blocks 1d9 in opposite directions along its circumference. The magnetic blocks 1d9 can be magnetically connected to the node ring 1d4 below it.

[0049] When the ventilation pipe group 1d is not opened, the node ring 1d4 on the second telescopic tube 1d1 and the node ring 1d4 on the fourth telescopic tube 1d3 are magnetically connected to the node ring 1d4 on the third telescopic tube 1d2 through the magnetic block 1d9, ensuring that the fourth telescopic tube 1d3 will not slide out due to its own weight when it is not extended.

[0050] An elastic switch 1k is installed on the lower side of the node ring 1d4 on the fourth telescopic tube 1d3, and a pressure head 1k0 is installed on the lower side of the node ring 1d4 on the third telescopic tube 1d2. The pressure head 1k0 can abut against the elastic switch 1k, and the elastic switch 1k is electrically connected to the exhaust fan 1i.

[0051] When the ventilation pipe assembly 1d is closed, the joint ring 1d4 of the fourth telescopic tube 1d3 is magnetically connected to the joint ring 1d4 of the third telescopic tube 1d2. At this time, the contact head 1k0 on the third telescopic tube 1d2 passes through the joint ring 1d4 of the fourth telescopic tube 1d3 and abuts against the elastic switch 1k, and the exhaust fan 1i is in the off state.

[0052] When the ventilation pipe group 1d is opened, the node ring 1d4 of the fourth telescopic tube 1d3 is separated from the node ring 1d4 of the third telescopic tube 1d2, the pressure head 1k0 is separated from the elastic switch 1k, the elastic switch 1k is opened, and the exhaust fan 1i starts and works.

[0053] The elastic switch 1k includes a switch base 1k1 and an elastic joint 1k2. The switch base 1k1 is fixedly mounted on the lower end of the node ring 1d4 of the fourth telescopic tube 1d3. The elastic joint 1k2 is mounted on the switch base 1k1 via two first springs 1k3. The two first springs 1k3 are each mounted below the switch base 1k1 via a bolt 1k4. The bolts 1k4 are vertically mounted at both ends of the switch. The two ends of the elastic joint 1k2 are sleeved on the bolts 1k4. The two ends of the first spring 1k3 respectively abut the lower ends of the elastic joint 1k2 and the bolt 1k4. The lower end of the touch pressure head 1k0 can pass through the switch base 1k1 and abut against the elastic joint 1k2. The switch base 1k1 is electrically connected to the exhaust fan 1i, and the elastic joint 1k2 is connected to an external power supply.

[0054] When the ventilation duct assembly 1d is closed, the joint ring 1d4 of the fourth telescopic tube 1d3 is still connected to the joint ring 1d4 of the third telescopic tube 1d2. The contact head 1k0 passes through the joint ring 1d4 of the fourth telescopic tube 1d3 and the switch base 1k1, pressing the elastic joint 1k2 downward. At this time, the first spring 1k3 is in a compressed state, the elastic joint 1k2 is not in contact with the switch base 1k1, and the exhaust fan 1i is not yet powered on.

[0055] When the ventilation pipe assembly 1d is opened, since the node ring 1d4 of the fourth telescopic tube 1d3 is still separated from the node ring 1d4 of the third telescopic tube 1d2, the contact pressure head 1k0 will also separate from the elastic joint 1k2. The first spring 1k3 resets and pushes up the elastic switch 1k, so that the elastic joint 1k2 is connected to the switch base 1k1, and then the exhaust fan 1i is connected to the power supply and starts to work.

[0056] The connection between the elastic joint 1k2 and the switch seat 1k1 is achieved through the cooperation of the bolt 1k4 and the first spring 1k3, which is convenient for disassembly, assembly and replacement, with a simple structure. By utilizing the worker's own weight, after the worker steps onto the maintenance platform 1f, the ventilation pipe group 1d automatically extends and turns on the exhaust fan 1i, and vice versa. There is no need for the worker to actively turn on the exhaust fan 1i, preventing the worker from forgetting to turn on the exhaust fan 1i for ventilation due to negligence. When the worker leaves, the exhaust fan 1i will be turned off as the ventilation pipe group 1d retracts, which also prevents the worker from forgetting to turn on the exhaust fan 1i when leaving, realizing the "turn on when coming and turn off when leaving" ventilation process of the rainwater pumping station, saving electricity.

[0057] The maintenance stand 1f is connected to the bottom of the pump station body 1 through a plurality of second springs 1f1 , and both ends of all the second springs 1f1 abut against the lower end of the maintenance stand 1f and the bottom of the pump station body 1 respectively.

[0058] When the maintenance worker has not stepped onto the maintenance platform 1f, the second spring 1f1 will lift the maintenance platform 1f to the plane where the top of the water inlet grille assembly 1e is located. When the maintenance worker steps onto the maintenance platform 1f, the maintenance platform 1f will be pressed down due to the worker's own weight, and the second spring 1f1 will contract, and it can ensure that the maintenance platform 1f moves downward to the plane where the bottom of the water inlet grille assembly 1e is located, and can be reset after the worker leaves.

[0059] A specific implementation method of an integrated rainwater pumping station with energy-saving exhaust comprises the following steps:

[0060] Step 1: Under normal conditions of the water pump station, the water inlet pipe group 1b discharges rainwater into the water inlet grille assembly 1e for processing, filtration and storage in the lower half of the pump station body 1. When internal drainage is required, the pump group 1a discharges the rainwater inside the pump station body 1 from the water outlet pipe group 1c. At this time, the ventilation pipe group 1d is not fully extended, and the pipe mouth of the uppermost telescopic pipe is exposed for natural ventilation. The second telescopic pipe 1d1 from top to bottom is now located inside the third telescopic pipe 1d2, and the fourth telescopic pipe 1d3 is located outside the third telescopic pipe 1d2. When the maintenance worker does not step onto the maintenance platform 1f, the second spring 1f1 lifts the maintenance platform 1f to the plane where the top of the water inlet grille assembly 1e is located. When the maintenance worker steps onto the maintenance platform 1f, the maintenance platform 1f is pressed down due to the worker's own weight, and the second spring 1f1 contracts, and can ensure that the maintenance platform 1f moves downward to the plane where the bottom of the water inlet grille assembly 1e is located, and can be reset after the worker leaves;

[0061] Step 2: After the maintenance worker enters the pump station body 1 from the ladder 1h inside the pump station body 1, when the maintenance worker stands on the maintenance platform 1f, the maintenance platform 1f slowly descends to the maintenance position, and at the same time, the pipe-pushing rack 1d7 on the maintenance platform 1f moves downward with the maintenance platform 1f and pushes the fourth telescopic tube 1d3, so that the fourth telescopic tube 1d3 extends downward, and at the same time drives the pull rope assembly 1g to extend the first telescopic tube 1d0 and the second telescopic tube 1d1 upward, so that the first telescopic tube 1d0 extends out of the top of the pump station body 1 and turns on the exhaust fan 1i; when the worker steps onto the maintenance platform 1f, the maintenance platform 1f drives the pipe-pushing rack 1d7 to move downward, and pushes the fourth telescopic tube 1d3. The pipe rack 1d7 drives the pipe-moving ring 1d6 and the fourth telescopic tube 1d3 downward, and at the same time pulls the two pull ropes 1g1 connected thereto, thereby pulling the second telescopic tube 1d1 upward via the fixed pulley 1g0. The other two pull ropes 1g1 pull the movable grid plate 1e1 upward as well. At the same time, the second telescopic tube 1d1 lifts the first telescopic tube 1d0 and extends it out of the top of the pump station body 1, thereby enhancing the ventilation effect. When the worker leaves the maintenance platform 1f, the maintenance platform 1f is reset. Due to the deadweight of the first and second telescopic tubes 1d0 and the movable grid plate 1e1 and their mutual connection, they are also reset.

[0062] Step 3: Before the maintenance worker enters the pump station body 1, the maintenance stand 1f and the external brush 1j are at the top plane of the main grille 1e0. When the pipe rack 1d7 moves downward with the maintenance stand 1f, the external brush 1j on the pipe rack 1d7 will also move downward and clean the outside of the main grille 1e0. Some of the bristles of the external brush 1j will pass through the grid holes of the main grille 1e0 due to elasticity to prevent the main grille 1e0 from being blocked. When the worker leaves the maintenance stand 1f, the maintenance stand 1f is reset, and the external brush 1j will reversely clean the main grille 1e0. The main grille 1e0 is automatically cleaned by the alternating movement of the external brush 1j and the movable grating 1e1, and the water inlet grille assembly 1e of the rainwater pump station is cleaned by the worker's own weight.

[0063] Step 4: When the ventilation duct assembly 1d is not open, the joint ring 1d4 of the fourth telescopic tube 1d3 is still connected to the joint ring 1d4 of the third telescopic tube 1d2. The contact pressure head 1k0 passes through the joint ring 1d4 of the fourth telescopic tube 1d3 and the switch base 1k1, pressing the elastic joint 1k2 downward. At this time, the first spring 1k3 is in a compressed state, the elastic joint 1k2 is not in contact with the switch base 1k1, and the exhaust fan 1i is not yet powered on.

[0064] When the ventilation pipe assembly 1d is opened, since the node ring 1d4 of the fourth telescopic tube 1d3 is still separated from the node ring 1d4 of the third telescopic tube 1d2, the contact pressure head 1k0 will also separate from the elastic joint 1k2. The first spring 1k3 resets and pushes up the elastic switch 1k, so that the elastic joint 1k2 is connected to the switch base 1k1, and then the exhaust fan 1i is connected to the power supply and starts to work.

[0065] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
