Description

Technical Field

[0001] This invention belongs to the technical field of floodproof door testing equipment, specifically relating to a water-circulating floodproof door testing chamber device and method. Background Technology

[0002] Flood doors are facilities used to prevent water from entering buildings, typically installed in basements, doorways, or low-lying areas. Through specially designed door panels, sealing systems, and drainage structures, they effectively prevent water from entering the interior, protecting the building from water damage. Flood doors usually undergo a flood test before leaving the factory to ensure their quality.

[0003] Chinese Patent Application No. 202421591766.7 discloses a floodproof door watertightness testing system, including a floodproof door test chamber, an air supply device, and a water tank. The test chamber has an installation interface on its side wall for sealing the floodproof door to be tested. The floodproof door can cooperate with the test chamber to form a test structure with a sealed cavity. The sealed cavity is used to store liquid and compressed air. The air supply device is connected to the test chamber via an air supply pipeline to supply compressed air to the sealed cavity. The water tank is placed below the test chamber and the test device to collect liquid dripping from the test chamber during the watertightness test. This patent's floodproof door watertightness testing system has a simple structure, is easy to implement, and can accurately test the watertightness of floodproof doors.

[0004] When conducting flood tests on floodgates, the flooding conditions vary. Some flooding occurs due to rising water levels at the bottom, while others are caused by external water impacts. Typically, testing equipment cannot automatically simulate these different situations and often requires the use of external water pressure equipment for simulation, resulting in high energy consumption and wasted water due to the inability to circulate it. Furthermore, it is difficult to ensure the airtightness of the testing equipment when simulating different flooding conditions, making efficient simulation difficult. Additionally, the testing device needs to consider the impact of impurities such as sludge in the water on the test. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a water-circulating floodgate test chamber device and method. Through the cooperation of a water storage tank, a water reservoir, a drainage pipe mechanism, and a pumping pipe mechanism, this invention can simulate the use of floodgates under different conditions, thereby enabling rapid and thorough testing of the floodgates. Simultaneously, the testing requires low energy consumption and can be reused. Furthermore, the structural cooperation between the swing mechanism and the water-sealing mechanism ensures that the water storage tank can maintain its water level without leakage, rapidly and thoroughly simulates different water impact test conditions, and facilitates silt removal.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A water-circulating floodgate test chamber device includes a test chamber body with an installation port at the front for installing a floodgate. The top of the test chamber body has a water passage opening, and the bottom of the test chamber body has multiple return water holes. A water storage tank is fixedly installed on the top of the test chamber body, and a water storage tank is fixedly installed on the bottom of the test chamber body. The bottom sidewall of the water storage tank has a first outlet and a first inlet symmetrically arranged, and the top sidewall of the water storage tank has a second inlet and a second outlet symmetrically arranged. The first outlet and the second inlet are fixedly connected by a drain pipe mechanism, and the first inlet and the second outlet are fixedly connected by a pumping pipe mechanism.

[0007] Furthermore, the drainage pipe mechanism includes a drainage pipe body on which a first valve is installed; the pumping pipe mechanism includes a pumping pipe body on which a pumping pump and a second valve are installed; the second valve is located above the pumping pump.

[0008] Furthermore, the bottom of the water storage tank is provided with an adjustment slot, which is connected to the water passage slot; a swing mechanism is installed on the adjustment slot, the swing mechanism includes a swing plate, a rotating shaft is fixedly provided on one side of the swing plate, and a rotating hole is provided on the adjustment slot and rotatably connected to the rotating shaft; a sliding groove is provided on the top of the swing plate, and a T-shaped slider is slidably connected on the sliding groove; a support plate is fixedly installed on the top of the water storage tank, and an electric telescopic rod is fixedly installed on the support plate; a hinge groove is fixedly provided on the T-shaped slider, and the telescopic end of the electric telescopic rod passes through the support plate and is hinged to the hinge groove through a fixed hinge block.

[0009] Furthermore, the swing plate is adapted to the adjustment slot, and a rubber sealing strip is fixed around the swing plate.

[0010] Furthermore, a water-sealing mechanism is provided inside the water passage opening. The water-sealing mechanism includes a stepped plate that is adapted to the water passage opening. Multiple sliding rods are fixedly provided at the bottom of the stepped plate, and multiple sliding holes are opened at the bottom of the test chamber. The sliding rods are slidably connected to the sliding holes. A limiting block is fixedly provided at the end of the sliding rod. A return spring is sleeved on the sliding rod, and the two ends of the return spring are fixedly connected to the bottom of the stepped plate and the bottom of the test chamber, respectively.

[0011] Furthermore, when the swing plate engages with the adjusting slot, the stepped plate engages with the water passage slot.

[0012] Furthermore, rubber sealing strips are fixed around the perimeter of the stepped plate.

[0013] Furthermore, the top of the side wall of the test chamber is provided with multiple ventilation holes.

[0014] Furthermore, a drain outlet and a valve are installed at the bottom of the side wall of the water storage tank.

[0015] This invention also claims a method for conducting tests using the above-described water-circulation type floodproof door test chamber device, comprising the following steps: S1. When stopping the test, close the first valve, open the second valve, and use a water pump to pump the water from the water storage tank into the water storage tank for storage until there is no water in the test chamber. Then stop pumping and close the second valve. Use the water storage tank to receive rainwater from the outside for daily water storage. S2. When conducting a water level rise test, after installing the floodgate, open the first valve to allow the water in the storage tank to automatically enter the water tank. At this time, the water level in the test chamber will rise continuously, thereby testing the sealing performance of the floodgate. S3. When conducting water impact testing, after installing the floodgate, the swing plate is tilted down to a fixed angle by controlling the electric telescopic rod, so that the step plate descends. This simulates the impact of various water bodies on the floodgate according to different angles, thereby testing the sealing and strength performance of the floodgate. S4. When dredging is carried out regularly, both the water storage tank and the water holding tank are filled with water. The swing plate is periodically flipped up by the electric telescopic rod, so that the water in the water storage tank, along with the silt, is discharged into the water holding tank through the drain pipe. After settling, the clean water above the water holding tank is pumped back to the water storage tank by the water pump, so that the silt settles to the bottom of the water holding tank for subsequent dredging.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) This invention, through the cooperation of the water storage tank, the water storage tank, the drainage pipe mechanism, and the pumping pipe mechanism, can simulate the use of floodgates under different conditions, thereby enabling rapid and thorough testing of the floodgates. Simultaneously, the testing requires low energy consumption and can be reused. Specifically, when conducting a water level rise test, after installing the floodgate, the first valve is opened, allowing water in the water storage tank to automatically enter the water storage tank. Due to the design of the return water hole at the bottom of the test chamber, the water level in the test chamber continuously rises, thus simulating the use of the floodgate when the water level rises from below, thereby testing the sealing performance of the floodgate. When conducting a water impact test, after installing the floodgate, the water can be allowed to pass through the bottom of the water storage tank by opening the equipment. The floodgate is emptied from the top to simulate the impact of water on it and the flooding situation, testing the sealing and strength performance of the floodgate. This comprehensive simulation of the floodgate's use under different conditions allows for rapid and thorough testing. After the water simulation is complete, the first valve is closed, the second valve is opened, and a water pump draws water from the storage tank into a reservoir for storage. Pumping continues until the test chamber is empty, at which point pumping stops, the second valve is closed, and the reservoir collects rainwater for daily storage, allowing for water reuse. Furthermore, no additional water storage or flushing simulation equipment is required, significantly reducing energy consumption and water waste.

[0017] (2) This invention, through the structural cooperation of the swing mechanism and the water-sealing mechanism, not only ensures that the water storage tank can store water without leakage, but also quickly and fully simulates different water impact test conditions, and facilitates sludge removal. Specifically, when storing water, the swing plate is controlled to engage with the adjusting slot by controlling the electric telescopic rod, and the adjusting slot is initially closed. At this time, the step plate is not blocked by the swing plate. Under the reset action of the return spring, the step plate engages with the water passage slot. The sealing is further achieved by the abutting seal of the step plate edges in different directions. Thus, the sealing performance is still guaranteed even when the tank is not completely sealed, ensuring that the water storage does not leak. Furthermore, when it is necessary to simulate different water impact tests, the swing plate is controlled to tilt down at a fixed angle by controlling the electric telescopic rod. The abutting of the swing plate against the step plate causes the step plate to descend synchronously, thereby opening the gap between the step plate and the water passage slot. At the same time, the downward movement of the swing plate... The different angles at which the water is tilted control the direction and intensity of the water impact, allowing for the simulation of various water impacts on the floodgate from different angles. This enables rapid and comprehensive simulation of different water impact test conditions. Meanwhile, over time, dust and impurities accumulate in the water storage tank, creating silt that can affect the test chamber. During periodic dredging, both the storage tank and the reservoir are filled with water. An electric telescopic rod controls the swing plate to periodically tilt upwards, agitating the water in the storage tank along with the silt, mixing the impurities in the water, and draining it all into the reservoir through the drain pipe. Once in the reservoir, the water settles, with the clear water on top and the silt settling at the bottom. Then, a water pump pumps the clear water from the reservoir back into the storage tank, ensuring the storage tank is free of silt and impurities, thus preventing interference with subsequent tests. The silt settles to the bottom of the reservoir, facilitating subsequent dredging without requiring climbing up for dredging. Attached Figure Description

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. Of course, the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0021] Although the steps in this invention are arranged by reference numerals, this is not intended to limit the order of the steps. Unless the order of the steps is explicitly stated or the execution of a step requires other steps as a basis, the relative order of the steps can be adjusted. It is understood that the term "and / or" as used herein refers to and covers any and all possible combinations of one or more of the associated listed items.

[0022] Example like Figures 1-7 As shown, a water-circulating floodgate test chamber device includes a test chamber body 100, an installation port 130 at the front of the test chamber body 100, on which a floodgate 200 is installed; a water passage trough 110 is opened at the top of the test chamber body 100, and multiple return water holes 140 are opened at the bottom of the test chamber body 100; a water storage tank 300 is fixedly installed at the top of the test chamber body 100, and a water storage tank 400 is fixedly installed at the bottom of the test chamber body 100; a first water outlet 310 and a first water inlet 320 are symmetrically opened at the bottom of the side wall of the water storage tank 300, and a second water inlet 410 and a second water outlet 420 are symmetrically opened at the top of the side wall of the water storage tank 400; the first water outlet 310 and the second water inlet 410 are fixedly connected by a drain pipe mechanism 500, and the first water inlet 320 and the second water outlet 420 are fixedly connected by a pumping pipe mechanism 600.

[0023] This invention, through the cooperation of the water storage tank 300, the water storage tank 400, the drainage pipe mechanism 500, and the pumping pipe mechanism 600, can simulate the use of the floodgate 200 under different conditions, thereby enabling rapid and thorough testing of the floodgate 100. At the same time, the energy required for testing is low and the device can be reused; a detailed description will follow.

[0024] Furthermore, the drain pipe mechanism 500 includes a drain pipe body 510, on which a first valve 520 is installed; the pumping pipe mechanism 600 includes a pumping pipe body 610, on which a pumping pump 630 and a second valve 620 are installed; the second valve 620 is located above the pumping pump 630.

[0025] When performing a water level rise test, after installing the floodgate 200, the first valve 520 is opened, allowing water in the storage tank 300 to automatically enter the reservoir 400. Due to the design of the return water hole 140 at the bottom of the test chamber 100, the water level in the test chamber 100 continuously rises, thus simulating the use of the floodgate 200 when the water level rises from below, thereby testing the sealing performance of the floodgate 200. When performing a water impact test, after installing the floodgate 200, the bottom device of the storage tank 300 is opened, allowing water to pour onto the floodgate 200 from the top, thus simulating the impact of water on the floodgate 200 and the flooding situation, testing the floodgate 200. The sealing and strength performance of the 00 comprehensively simulates the use of the floodproof door 200 under different conditions, thereby enabling rapid and thorough testing of the floodproof door 100. Simultaneously, after the water simulation is complete, the first valve 520 is closed, the second valve 620 is opened, and the water in the water storage tank 400 is pumped into the water storage tank 300 by the water pump 630 until there is no water in the test chamber 100. Pumping then stops, and the second valve 620 is closed. The water storage tank 300 is used to collect rainwater for daily water storage, allowing for water reuse. Furthermore, no additional water storage equipment or flushing simulation equipment is required during the test, significantly reducing energy consumption and water waste.

[0026] It is worth noting that the water pump 630 and other electrical equipment of the present invention are all powered by an external power source, which is a conventional setup and will not be described in detail here.

[0027] Furthermore, the bottom of the water storage tank 300 is provided with an adjustment slot 330, which is connected to the water passage slot 110; a swing mechanism 700 is installed on the adjustment slot 330, the swing mechanism 700 includes a swing plate 730, a rotating shaft 731 is fixedly provided on one side of the swing plate 730, the adjustment slot 330 is provided with a rotating hole and is rotatably connected to the rotating shaft 731; a sliding groove 732 is provided on the top of the swing plate 730, and a T-shaped slider 740 is slidably connected to the sliding groove 732; a support plate 720 is fixedly installed on the top of the water storage tank 300, and an electric telescopic rod 710 is fixedly installed on the support plate 720; a hinge groove 741 is fixedly provided on the T-shaped slider 740, the telescopic end of the electric telescopic rod 710 passes through the support plate 720 and the telescopic end is hinged to the hinge groove 741 through a fixed hinge block 711.

[0028] The present invention, through the structural cooperation of the swing mechanism 700 and the water-sealing mechanism 800, not only ensures that the water storage tank 300 can store water without leakage, but also can quickly and fully simulate different water impact test conditions, and at the same time facilitates sludge removal; a detailed description will follow.

[0029] Furthermore, the swing plate 730 is adapted to the adjustment slot 330, and a rubber sealing strip is fixed around the swing plate 730.

[0030] Furthermore, a water-sealing mechanism 800 is provided inside the water passage 110. The water-sealing mechanism 800 includes a stepped plate 810, which is adapted to the water passage 110. A plurality of sliding rods 820 are fixedly provided at the bottom of the stepped plate 810, and a plurality of sliding holes are opened at the bottom of the test chamber 100. The sliding rods 820 are slidably connected to the sliding holes. A limiting block 821 is fixedly provided at the end of the sliding rod 820. A return spring 830 is sleeved on the sliding rod 820, and the two ends of the return spring 830 are fixedly connected to the stepped plate 810 and the bottom of the test chamber 100, respectively.

[0031] When water is stored, the present invention controls the swing plate 730 to engage with the adjusting slot 330 by controlling the electric telescopic rod 710. The adjusting slot 330 is initially closed, and at this time, the stepped plate 810 is not blocked by the swing plate 730. Under the reset action of the return spring 830, the stepped plate 810 engages with the water passage slot 110. The abutment seal of the stepped plate 810 in different directions is used to achieve further sealing, thus ensuring sealing performance even when it is not completely sealed and fixed, ensuring that water storage does not leak. Furthermore, when it is necessary to simulate different water impact tests, the electric telescopic rod 710 controls the swing plate 730 to tilt downwards at a fixed angle. The abutment of the swing plate 730 on the stepped plate 810 causes the stepped plate 810 to descend synchronously, thereby opening the gap between the stepped plate 810 and the water passage slot 110. At the same time, the different angles at which the swing plate 730 tilts downwards control the direction and intensity of the water impact, thus allowing for simulation at different angles. The system simulates the impact of various water bodies on the floodgate 200, enabling rapid and comprehensive simulation of different water impact test conditions. However, over time, dust and impurities accumulate in the water storage tank 300, leading to siltation that can affect the test chamber. During periodic dredging, both the water storage tank 300 and the reservoir 400 are filled with water. An electric telescopic rod 710 controls the swing plate 730 to periodically tilt upwards, agitating the water in the water storage tank 300 along with the silt. This mixes the impurities in the water, which is then discharged into the reservoir 400 through the drain pipe 510. After entering the reservoir 400, the water settles, with the clear water at the top and the silt at the bottom. Then, a water pump 630 pumps the clear water from the reservoir 400 back into the water storage tank 300. This ensures that the water storage tank 300 is free of silt and impurities, preventing interference with subsequent tests, while allowing the silt to settle to the bottom of the reservoir 400 for easy dredging without requiring climbing to remove it.

[0032] Furthermore, when the swing plate 730 is engaged with the adjusting slot 330, the step plate 810 is engaged with the water passage slot 110.

[0033] Furthermore, rubber sealing strips are fixed around the perimeter of the stepped plate 810.

[0034] Furthermore, the top of the side wall of the test chamber 100 is provided with multiple ventilation holes 120. The ventilation holes 120 can further ensure water circulation.

[0035] Furthermore, a drain outlet and a valve are installed at the bottom of the side wall of the water storage tank 400. The drain outlet and valve facilitate subsequent dredging, which will not be described in detail here.

[0036] A method for conducting tests using the aforementioned water-circulation type floodproof door test chamber device includes the following steps: S1. When the test is stopped, close the first valve 520, open the second valve 620, and use the water pump 630 to pump the water in the water storage tank 400 into the water storage tank 300 for water storage until there is no water in the test chamber 100. Then stop pumping water and close the second valve 620. Use the water storage tank 300 to receive rainwater from the outside for daily water storage. S2. When the water level rise test is carried out, after the floodgate 200 is installed, the first valve 520 is opened so that the water in the water storage tank 300 automatically enters the water storage tank 400. At this time, the water level in the test chamber 100 rises continuously, thereby testing the sealing performance of the floodgate 200. S3. When conducting water impact testing, after installing the floodgate 200, the swing plate 730 is tilted down to a fixed angle by the electric telescopic rod 710, so that the step plate 810 is lowered. This simulates the impact of various water bodies on the floodgate 200 at different angles, thereby testing the sealing and strength performance of the floodgate 200. S4. When dredging is carried out regularly, both the water storage tank 300 and the water storage tank 400 are filled with water. The swing plate 730 is periodically flipped upward by the electric telescopic rod 710, so that the water in the water storage tank 300, along with the silt, is discharged into the water storage tank 400 through the drain pipe body 510. After settling, the clean water above the water storage tank 400 is pumped back to the water storage tank 300 by the water pump 630, so that the silt settles to the bottom of the water storage tank 400 for subsequent dredging.

[0037] It is worth noting that the floodgate 200 is installed with the assistance of an external movable frame. The specific installation method of the floodgate 200 is not the focus of this invention; conventional settings are sufficient and will not be described in detail here.

[0038] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.

The swing plate (730) is periodically flipped up by the electric telescopic rod (710), so that the water in the water storage tank (300) along with the silt is discharged into the water storage tank (400) through the drain pipe body (510). After standing, the clean water above the water storage tank (400) is pumped back to the water storage tank (300) by the water pump (630), so that the silt settles to the bottom of the water storage tank (400) for subsequent dredging.
