[0002] One of the purposes of basement sump pits is to collect water flowing from the basement floor and discharge it promptly via pumps. Current technology involves arranging relatively independent sump pits to discharge water from different areas. However, when the local water flow is too large, the pumps in some sump pits may be unable to discharge the water in time, and the pumps in the other sump pits may not function. Summary of the Invention

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a basement water collection well connected drainage device, which includes a water collection well;

[0007] Parallel water pipes are installed at the bottom of the water collection wells for connecting the water collection wells;

[0008] A drainage unit is disposed at both ends of the parallel water pipe; the drainage unit includes a positioning component fixedly connected to the parallel water pipe, a blocking component slidably disposed within the positioning component, and a starting component disposed on the top of the positioning component.

[0009] As a preferred embodiment of the basement sump drainage device of the present invention, a water-stop ring is provided on the parallel water pipe; the water-stop ring includes a metal ring, an installation groove provided on the inner side wall of the metal ring, a rubber ring provided in the installation groove, and a limiting mechanism provided on the outer side of the metal ring; the rubber ring is provided between the metal ring and the parallel water pipe.

[0010] As a preferred embodiment of the basement sump drainage device of the present invention, the limiting mechanism includes a first groove disposed on the outer wall of the metal ring, a second groove disposed on one side of the first groove, and a protruding ring disposed between the first groove and the second groove.

[0011] As a preferred embodiment of the basement sump drainage device of the present invention, the end face of the metal ring is provided with multiple sets of through holes.

[0012] As a preferred embodiment of the basement water collection well interconnection drainage device of the present invention, the positioning component includes a positioning plate fixedly disposed at one end of the parallel water pipe; the positioning plate is provided with a first sliding groove; the positioning plate is provided with a flow channel opening coaxial with the parallel water pipe.

[0013] As a preferred embodiment of the basement sump drainage device of the present invention, the blocking component includes a sliding baffle slidably disposed in the first trough, a rotating shaft disposed on the side of the positioning plate away from the parallel water pipe, and a valve hinged on the rotating shaft, the valve being the same size as the flow channel opening; a reset component is disposed between the rotating shaft and the valve.

[0014] As a preferred embodiment of the basement sump drainage device of the present invention, the sliding baffle is provided with multiple sets of first blocking strips and first openings, the first blocking strips and first openings being alternately arranged; the valve is provided with multiple sets of second blocking strips and second openings, the second blocking strips and second openings being alternately arranged; the widths of the first blocking strips, the first openings, the second blocking strips, and the second openings are all the same. In the initial state, the first blocking strips and the second openings correspond to each other, so that the valve and the sliding baffle form a closed state; when the sliding baffle is moved under the action of the starting component, the first openings and the second openings correspond to each other, and the two form a channel for fluid to flow out.

[0015] As a preferred embodiment of the basement sump drainage device of the present invention, the starting component includes an electromagnet disposed on the top of the positioning plate, a sliding channel disposed on the top of the electromagnet, a trigger disposed on the end of the sliding block away from the electromagnet, and a buoyancy component slidably disposed in the sliding channel; the sliding baffle is made of galvanized iron.

[0016] As a preferred embodiment of the basement sump drainage device of the present invention, wherein: a second sliding groove is provided at both ends of the sliding channel in the width direction; the buoyancy component includes a sliding block slidably disposed in the second sliding groove, rollers that cooperate with the second sliding groove are provided at both ends of the sliding block, and a buoyancy ball is provided on the sliding block.

[0017] A drainage method for a basement sump connected to a drainage device, as described above, specifically includes the following steps:

[0018] Step 1: When rainwater falls into the collection well, if the amount of rainwater is normal and the pump in the collection well can meet the drainage requirements, the connecting drainage device will not be activated.

[0019] Step 2: When the rainfall surges, the water volume in the local collection well surges, triggering the connection of the drainage device. The buoyancy ball moves upward in the sliding channel as the water in the collection well rises.

[0020] Step 3: When the buoyancy ball drives the sliding block to rise until it touches the trigger, the trigger energizes the electromagnet to generate a magnetic force that will attract the sliding baffle.

[0021] Step 4: When the sliding baffle is subjected to the magnetic force of the electromagnet, it rises, so that the first port corresponds to the second port, forming a channel for fluid to flow out.

[0022] Step 5: The fluid is discharged through the parallel water pipe to the next collection well. The valve in the collection well opens around the pivot in the direction of water flow, and the collection wells form a parallel effect to relieve the local water pumping pressure.

[0023] The beneficial effects of this invention are as follows: This invention connects basement sump pits in parallel via water pipes, thereby balancing the drainage workload of each sump pit. When the drainage volume of a local sump pit is too high, the integrated sump pit and drainage structure activates the drainage device, distributing the water flow to sump pits with smaller water volumes, allowing other sump pits to function properly, reducing the drainage pressure on local sump pits, and significantly improving drainage performance. This invention has the advantages of strong drainage performance and high practicality, and is suitable for parallel drainage of basement sump pits and optimization of sump pit drainage performance.

Implementation

[0035] Example

[0036] Reference Figures 1-9 As shown, this is the first embodiment of the present invention, which provides a drainage device and drainage method for connecting a basement sump well. Figure 8As shown, this invention connects basement sump pits in parallel via water pipes, balancing the drainage workload of each sump pit. When a local sump pit experiences excessive drainage, the integrated sump pit and drainage system activates the drainage device, distributing water flow to sump pits with smaller water volumes. This allows other sump pits to fulfill their drainage function, reducing the drainage pressure on local sump pits and significantly improving drainage performance. This invention offers advantages such as strong drainage performance and high practicality, and is suitable for parallel drainage of basement sump pits and optimization of sump pit drainage performance.

[0037] Specifically, the water collection well is 100;

[0038] A parallel water pipe 200 is installed at the bottom of the water collection well 100 for connecting the water collection wells 100;

[0039] A drainage unit 300 is disposed at both ends of the parallel water pipe 200; the drainage unit 300 includes a positioning component 301 fixedly connected to the parallel water pipe 200, a blocking component 302 slidably disposed within the positioning component 301, and a starting component 303 disposed on the top of the positioning component 301.

[0040] It should be noted that the water collection well 100 is equipped with a drainage pump, which is existing technology and will not be elaborated here.

[0041] Better, refer to Figures 8-9 Under normal rainfall conditions, the pumping speed of the collection well 100 meets the requirements, eliminating the need to activate the connecting drainage device. This ensures the normal pumping function of the individual collection well 100, preventing drainage to other collection wells 100 and keeping them dry. However, during periods of heavy rainfall, the water volume in a local collection well 100 surges, making it difficult to maintain the required pumping speed. The water level in the collection well 100 rises, triggering the connecting drainage device of this invention. The device opens, releasing water from the local collection well 100 to other collection wells 100, thus relieving the pumping pressure on the local collection well 100.

[0042] Preferably, the parallel water pipes 200 are PVC water pipes, with a preferred pipe diameter of 100mm.

[0043] Furthermore, a water-stop ring 201 is provided on the parallel water pipe 200; the water-stop ring 201 includes a metal ring 201a, a mounting groove 201b disposed on the inner sidewall of the metal ring 201a, a rubber ring disposed in the mounting groove 201b, and a limiting mechanism 201c disposed on the outer side of the metal ring 201a; the rubber ring is disposed between the metal ring 201a and the parallel water pipe 200.

[0044] It should be noted that the water-stop ring 201 is fixed 100mm from the end of the parallel water pipe 200.

[0045] Preferably, the rubber ring 201c is an elastic expansion rubber ring 201c. The elastic expansion rubber ring 201c expands when it comes into contact with water, making it more tightly connected with the parallel water pipe 200, thus solving the leakage problem between the parallel water pipe 200 and the rubber ring 201c.

[0046] Furthermore, such as Figures 2-3 As shown, the limiting mechanism 201c includes a first groove 201c-1 disposed on the outer wall of the metal ring 201a, a second groove 201c-2 disposed on one side of the first groove 201c-1, and a protruding ring 201c-3 disposed between the first groove 201c-1 and the second groove 201c-2.

[0047] It should be noted that when concrete 500 is poured, concrete 500 fully enters the first groove 201c-1 and the second groove 201c-2. After the concrete 500 solidifies, it forms a limiting structure with the raised ring 201c-3 respectively. The entire water-stop ring 202 is locked with the concrete 500 after solidification, making the connection between the parallel water pipe 200 and the concrete 500 more stable.

[0048] Furthermore, the end face of the metal ring 201a is provided with multiple sets of through holes 201d.

[0049] It should be noted that after the concrete 500 is poured, it enters the opening 201d, increasing the contact area between the metal ring 201a and the concrete 500, thus achieving a tighter fit. Furthermore, protrusions can be provided on the end face of the metal ring 201a. This further increases the contact area between the metal ring 201a and the concrete 500, making the connection between the water-stop ring 201a and the concrete 500 more stable.

[0050] Furthermore, such as Figures 4-5 As shown, the positioning component 301 includes a positioning plate 301a fixedly disposed at one end of the parallel water pipe 200; the positioning plate 301a is provided with a first sliding groove 301b; the positioning plate 301a is provided with a flow channel opening coaxial with the parallel water pipe 200.

[0051] Furthermore, the blocking assembly 302 includes a sliding baffle 302a slidably disposed in the first groove 301b, a rotating shaft 302b disposed on the side of the positioning plate 301a away from the parallel water pipe 200, and a valve 302c hingedly disposed on the rotating shaft 302b, the valve 302c being the same size as the flow channel opening; a reset member is disposed between the rotating shaft 302b and the valve 302c.

[0052] It should be noted that the reset component is a torque spring, and the valve 302c consists of two doors, left and right, respectively hinged to the rotating shaft 302b. When the valve 302c is impacted by water flow, it will open in the direction of water flow. When there is no water flow, it will automatically reset due to the elastic force of the torque spring, and the valve will be in the closed state.

[0053] Furthermore, the sliding baffle 302a is provided with multiple sets of first blocking bars 302a-1 and first openings 302a-2, with the first blocking bars 302a-1 and first openings 302a-2 alternating; the valve 302c is provided with multiple sets of second blocking bars 302c-1 and second openings 302c-2, with the second blocking bars 302c-1 and second openings 302c-2 alternating; the first blocking bars 302a-1, the first openings 302a-2, The second blocking strip 302c-1 and the second through-hole 302c-2 have the same width. In the initial state, the first blocking strip 302a-1 corresponds to the second through-hole 302c-2, so that the valve 302c and the sliding baffle 302a form a closed state. When the sliding baffle 302a is moved under the action of the starting component 303, the first through-hole 302a-2 corresponds to the second through-hole 302c-2, and the two form a channel for fluid to flow out.

[0054] It should be noted that when the starting component 303 moves the sliding baffle 302a upward by a distance exactly equal to the width of the first blocking bar 302a-1, the first opening 302a-2, the second blocking bar 302c-1, and the second opening 302c-2, the first opening 302a-2 and the second opening 302c-2 correspond after the movement, forming a fluid channel between them. The fluid flows to the next water collection well 100. At this time, the valve 302c and the sliding baffle 302a are in a closed state in the water collection well 100 to which the fluid flows. Therefore, under the impact of the water flow, the water flows through the first opening 302a-2 and hits the second blocking bar 302c-1. As a result, the valve 302c will open in the direction of the water flow, discharging the water in one water collection well 100 into another water collection well 100, thereby relieving the drainage pressure of the local water collection well.

[0055] Furthermore, the starting component 303 includes an electromagnet 303a disposed on the top of the positioning plate 301a, a sliding channel 303b disposed on the top of the electromagnet 303a, a trigger 303c disposed on the end of the sliding block 303b away from the electromagnet 303a, and a buoyancy component 303d slidably disposed in the sliding channel 303b; the sliding baffle 302a is made of galvanized iron material.

[0056] Furthermore, the sliding channel 303b has a second groove 303b-1 at both ends in the width direction; the buoyancy component 303d includes a sliding block 303d-1 slidably disposed in the second groove 303b-1, the two ends of the sliding block 303d-1 are provided with rollers 303d-2 that cooperate with the second groove 303b-1, and the sliding block 303d-1 is provided with a buoyancy ball 303d-3.

[0057] It should be noted that, under normal conditions, the sliding baffle 302a rests at the bottom due to its own weight. As the water level in the collection well 100 rises, the buoyancy ball 303d-3 also rises. When the buoyancy ball 303d-3 rises, it drives the sliding block 303d-1 to move upward along the sliding channel 303b until it touches the trigger 303c. The trigger 303c opens the switch, causing the electromagnet 303a to switch its magnetism and generate magnetic force. Because the sliding baffle 302a is made of galvanized iron, it is attracted by the magnetic force and rises by the width of the first opening 302a-2. At this time, the first opening 302a-2 and the second opening 302c-2 on the valve 302c correspond to and overlap, forming a channel. When the water or fluid in the collection well 100 is completely drained, the trigger switch can be closed by external contact, so that the sliding baffle 302a is no longer affected by the magnetic force and falls under its own weight. The valve 302c and the sliding baffle 302a form a closed state. Alternatively, a magnetic force dissipation switch can be placed near the electromagnet 303a. After the buoyancy ball 303d-3 touches it, it can be set to wait for a certain period of time before turning off the magnetic force.

[0058] A drainage method for connecting a basement sump to a drainage system specifically includes the following steps:

[0059] Step 1: When rainwater falls into the collection well 100, if the amount of rainwater is normal and the pump in the collection well 100 can meet the drainage requirements, the connecting drainage device will not be activated.

[0060] Step 2: When the rainfall surges, the water volume in the local water collection well 100 surges, triggering the connection of the drainage device. The buoyancy ball 303d-3 moves upward in the sliding channel 303b as the water in the water collection well 100 rises.

[0061] Step 3: When the buoyancy ball 303d-3 drives the sliding block 303d-1 to rise until it touches the trigger 303c, the trigger 303c causes the electromagnet 303a to be energized to generate a magnetic force that will attract the sliding baffle 303a.

[0062] Step 4: When the sliding baffle 303a is subjected to the magnetic force of the electromagnet 303a, it rises, so that the first port 302a-2 corresponds to the second port 302c-2, forming a channel for fluid to flow out.

[0063] Step 5: The fluid is discharged through the parallel water pipe 200 to the next collection well 100. The valve 302c in the collection well 100 opens around the rotating shaft 302b in the direction of water flow. The collection wells 100 form a parallel effect to relieve the local water pumping pressure of the collection well 100. Example

[0064] Reference Figures 8-9 As shown, this is the second embodiment of the present invention, which differs from the first embodiment in that: this embodiment also includes a construction method for an integrated structure of basement water collection well and drainage.

[0065] It should be noted that the parallel water pipe 200 is fixed to the bottom of the water collection well 100 by the fixed steel bar 400, and water-stop rings 201 are installed 100mm from both ends of the parallel water pipe 200. A drainage device is installed at the port of the parallel water pipe 200.

[0066] Preferably, the parallel water pipe 200 is a PVC water pipe, with a preferred diameter of 100mm. The bottom height of the parallel water pipe 200 is the same as the bottom height of the collection well 100, and it is arranged horizontally. The water-stop ring 201 is fixed 100mm from the end of the parallel water pipe 200. The fixing steel bar 400 is a steel bar with a diameter of 10mm and a length of 300mm. Three steel bars 400 are tied in a triangle on the outside of the parallel water pipe 200 to form a set of fixing steel bars 400. The fixing steel bars 400 are evenly distributed along the longitudinal direction of the parallel water pipe 200, and the spacing should preferably be 1500mm.

[0067] Reference Figures 8-9 The integrated structural construction method for drainage in this embodiment includes the following steps:

[0068] Step 1: Based on the layout of the basement sump 100 in the design drawings, determine the number, length and location of the parallel water pipes 200, draw a layout plan of the parallel water pipes 200, and indicate the length of the parallel water pipes 200 and the number of fixing steel bars 400 at each location.

[0069] Step 2: Purchase PVC water pipes, 400mm steel bars, and 201mm waterstop rings; prepare steel bar installers, construction workers, quality inspectors, and other construction technicians.

[0070] Step 3: According to the plan layout of the parallel water pipe 200, before the foundation reinforcement 400 is tied, mark the position of the parallel water pipe 200 with a chalk line.

[0071] Step 4: Cut the PVC water pipe to the designed length according to the parallel water pipe 200 plan layout, fix the water-stop rings 201 at both ends, and seal the pipe ends with tape.

[0072] Step 5: Cut the 10mm diameter steel bars into 300mm lengths, process them according to the design quantity, arrange them neatly, and wait for use;

[0073] Step 6: After the reinforcement 400 at the bottom of the foundation is tied, according to the plan of the parallel water pipe 200 and the location of the site layout, tie the parallel water pipe 200 firmly with the reinforcement 400 and fix it in the design position.

[0074] Step 7: During the pouring of 500mm of concrete for the foundation, check whether the position of the parallel water pipe 200 has shifted, and check whether the pipe body of the parallel water pipe 200 is damaged, and repair it in a timely manner. After the 500mm of concrete for the foundation is poured, remove the tape from both ends of the parallel water pipe 200, check the connection, and confirm that the pipe is unobstructed and free of foreign objects. The construction of the integrated drainage structure of the basement sump is now complete.

[0075] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
