Description

Technical Field

[0001] This utility model relates to the field of floor drain performance testing technology, and in particular to a comprehensive floor drain performance testing device. Background Technology

[0002] As a key component of building drainage systems, the performance of floor drains directly affects the drainage efficiency and user experience in kitchens and bathrooms. In practical applications, users often encounter problems such as slow drainage, odor backflow, and blockage by debris. These problems largely stem from insufficient design performance of the floor drains themselves or the failure to effectively evaluate them under real-world conditions. However, current testing methods and equipment for floor drain performance have significant limitations and cannot meet the needs for scientific and comprehensive evaluation.

[0003] Traditional testing methods mainly focus on single tests such as structural sealing or foundation drainage speed, which has the following shortcomings: Lack of quantitative comparison capability: Conventional methods are insufficient for accurately and visually quantifying the actual drainage volume of multiple floor drains within the same time period. They often rely on subjective feelings or simple visual estimation of water flow time, resulting in coarse data with poor comparability.

[0004] Ignoring real-world clogged environments: Most tests are conducted in clean pipe environments, failing to effectively simulate the complex scenarios of hair, debris, and other contaminants accumulating and covering the drain surface in real-world use. This makes it impossible to assess the product's residual drainage capacity (i.e., anti-clogging performance) under partial or even severe clogging conditions, which is precisely the core pain point for users. Therefore, a comprehensive drain performance testing device is proposed to address these issues. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0006] Therefore, one objective of this utility model is to propose a comprehensive testing device for floor drain performance, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0007] To achieve the above objectives, one embodiment of the present invention provides a comprehensive testing device for floor drain performance, comprising a chamber, a support column, and compartments. The bottom of the chamber is fixedly connected to the support column, and the interior of the chamber is provided with a plurality of compartments, with floor drains installed at the bottom of the inner side of each compartment. The bottom of the chamber is detachably connected to a base, and a collection pipe is fixedly connected to the bottom of the base. The collection pipe is transparent, and a solenoid valve is fixedly connected to the top of the collection pipe. The collection pipe has graduations engraved on its wall, and several positioning holes are provided on the bottom surface of the inner side of the compartment. Pins are inserted into the positioning holes, and a grid plate is fixedly connected to the top of the pins. The grid plate covers the surface of the drain.

[0008] Preferably, in any of the above solutions, the silo body is made of PVC and is bonded to the support column.

[0009] The above technical solution is adopted: This device is specifically used to test the performance of floor drains, specifically to test the amount of water discharged from the floor drain within a fixed time.

[0010] The basic working principle is as follows: different floor drain products are installed inside the compartment. A certain amount of water is injected into the compartment, and the solenoid valve is opened and closed by an external signal. The floor drain starts to drain normally, and the collection pipe collects the water. After a fixed time, the solenoid valve is closed. The collection pipe is columnar and transparent, and its surface has scales, so the liquid level can be clearly seen. In this way, the amount of water drained by the corresponding floor drain within a fixed time is displayed intuitively.

[0011] The core advantages of this device, employing the above technical solution, are: It uses a cylindrical, transparent collection tube with graduated markings on its surface, allowing for clear visualization of the liquid level. This enables a direct comparison of the drainage performance of multiple floor drain products. Furthermore, through the coordinated design of positioning holes, pins, and a mesh plate, a mesh plate made of corrosion-resistant plastic can be detachably connected to the floor drain surface. Simulating real-world usage environments (such as hair and debris accumulation), the device tests the performance of the floor drain under different levels of clogging. The mesh plate can be easily removed for cleaning or replacement. This allows the device to not only test drainage volume under clean conditions but also evaluate anti-clogging performance, more closely reflecting actual application scenarios.

[0012] Preferably, in any of the above schemes, the height of the support column is greater than the total height of the base and the collection pipe.

[0013] Preferably, in any of the above solutions, the base is threadedly connected to the chamber body, and the collection tube is made of tempered glass.

[0014] Device Composition: The device consists of a tank body and a supporting structure. The tank body is made of corrosion-resistant PVC material to reduce overall weight. The support column is firmly connected to the tank body using industrial adhesive. The height design must meet the requirement that the support column height > the base height + the collection pipe height, ensuring that the collection pipe is suspended for easy observation of the liquid level and disassembly for maintenance. The test unit structure features a threaded connection between the base and the tank body for quick assembly and disassembly, facilitating cleaning or replacement of the collection pipe. The collection pipe is made of cylindrical tempered glass, offering high transparency and impact resistance, with millimeter-level graduations for precise liquid level readings. The solenoid valve is a timed normally closed solenoid valve (e.g., model DN15-ZQDF), with opening and closing times set via an external controller, achieving an accuracy of ±0.1 seconds.

[0015] The clog simulation component features symmetrically distributed positioning holes on the bottom surface of the compartments surrounding the drain. The pins and mesh plate are integrally molded from nylon, making them water- and corrosion-resistant. The mesh plate is replaceable, with 5mm holes to simulate hair and debris buildup. Users can adjust the clog level by replacing the mesh plate with one of different hole diameters or levels of dirt.

[0016] Preferably, of any of the above solutions, the solenoid valve is model DN15-ZQDF, and the solenoid valve is timed.

[0017] Preferably, in any of the above solutions, the pins are located around the drain, and the grid plate simulates the environment where hair and debris accumulate on the drain.

[0018] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: This comprehensive floor drain performance testing device uses a cylindrical transparent collection tube with graduations on its surface for clear liquid level monitoring. This allows for a direct comparison of the drainage performance of multiple floor drain products. Through the coordinated design of positioning holes, pins, and a mesh plate, a mesh plate made of corrosion-resistant plastic can be detachably connected to the floor drain surface. Simulating real-world usage environments (such as hair and debris accumulation), the device tests the performance of floor drains under different levels of clogging. The mesh plate can be easily removed for cleaning or replacement. This allows the device to not only test drainage volume under clean conditions but also evaluate anti-clogging performance, more closely reflecting real-world application scenarios.

[0024] like Figure 1-4 As shown, the local leakage performance comprehensive testing device includes a chamber 1, a support column 2, and a compartment 3. The bottom of the chamber 1 is fixedly connected to the support column 2. Several compartments 3 are opened inside the chamber 1, and a floor drain 4 is installed at the bottom of the inner side of the compartment 3. The bottom of the chamber 1 is detachably connected to a base 5, and a collection pipe 6 is fixedly connected to the bottom of the base 5. The collection pipe 6 is transparent, and a solenoid valve 7 is fixedly connected to the top of the collection pipe 6. The collection pipe 6 has engraved scales on its wall. Several positioning holes 8 are opened on the bottom surface of the inner side of the compartment 3. Pins 9 are inserted into the positioning holes 8. A grid plate 10 is fixedly connected to the top of the pins 9. The grid plate 10 covers the surface of the drain 4.

[0025] Example 1: The chamber body 1 is made of PVC and is bonded to the support column 2. The height of the support column 2 is greater than the total height of the base 5 and the collection pipe 6. The base 5 is threaded to the chamber body 1, and the collection pipe 6 is made of tempered glass. The solenoid valve 7 is model DN15-ZQDF and is timed. The pins 9 are located around the drain 4, and the mesh plate 10 simulates the environment where hair and debris accumulate on the drain 4.

[0026] Example 2: This device is specifically used to test the performance of floor drain 4, specifically to test the amount of water discharged from floor drain 4 within a fixed time period.

[0027] The basic working principle is as follows: different floor drains 4 are installed inside the compartment 3. A certain amount of water is injected into the compartment 3. The solenoid valve 7 is opened and closed by an external signal, and the floor drain 4 starts to drain normally. The collection pipe 6 collects the drain water. After a fixed time, the solenoid valve 7 is closed. The collection pipe 6 is columnar and transparent, and its surface has scales, so the liquid level can be clearly seen. In this way, the amount of water drained by the corresponding floor drain 4 within a fixed time is displayed more intuitively.

[0028] The device consists of: a chamber 1 and a supporting structure. The chamber 1 is made of corrosion-resistant PVC material to reduce overall weight. The support column 2 is firmly connected to the chamber 1 using industrial adhesive. The height design must meet the requirement that the height of the support column 2 > the height of the base 5 + the height of the collection pipe 6, ensuring that the collection pipe 6 is suspended for easy observation of the liquid level and disassembly / maintenance. The test unit structure includes a base 5 connected to the chamber 1 via a threaded interface for quick assembly and disassembly, facilitating cleaning or replacement of the collection pipe 6. The collection pipe 6 is made of cylindrical tempered glass, offering high transparency and impact resistance, with millimeter-level graduations for precise liquid level readings. The solenoid valve 7 is a timed normally closed solenoid valve (e.g., model DN15-ZQDF), with opening and closing times set via an external controller, achieving an accuracy of ±0.1 seconds.

[0029] The clogging simulation component has positioning holes 8 symmetrically distributed on the bottom surface of the compartments 3 around the drain 4. The pins 9 and the grid plate 10 are integrally molded and made of nylon, which is water-resistant and corrosion-resistant. The grid plate 10 is a replaceable design with a hole diameter of 5mm to simulate the accumulation of hair and debris. Users can replace the grid plate 10 with different hole diameters or degrees of dirt to adjust the clogging level.

[0030] The working principle of this utility model is as follows: Preparation: Install the drain 4 to be tested at the bottom of compartment 3. Select either a clean mesh plate 10 or a mesh plate 10 pre-filled with blockage, depending on the testing requirements. Insert the pin 9 into the positioning hole 8 so that the mesh plate 10 covers the surface of the drain 4. Tighten the base 5 to ensure that the collection pipe 6 is sealed and connected to the drain outlet of the drain 4.

[0031] To perform the test, inject a measured amount of clean water (e.g., 10L) into compartment 3. Activate solenoid valve 7 via an external controller, and start timing simultaneously. The water flows through floor drain 4 and mesh plate 10 before entering collection pipe 6. After a preset time (e.g., 30 seconds), solenoid valve 7 automatically closes, cutting off the water flow.

[0032] Results reading and analysis: Observe the scale value corresponding to the liquid level in collection tube 6, and directly read the volume of the discharged water.

[0033] By comparing the liquid level height of floor drains 4 in different compartments 3 within the same time period, their water flow performance and anti-clogging ability can be evaluated intuitively.

[0034] Compared with the prior art, the present invention has the following advantages: This comprehensive drain performance testing device uses a cylindrical transparent collection tube 6 with graduations on its surface for clear liquid level monitoring. This allows for a direct comparison of the drainage performance of multiple drain products 4. Simultaneously, through the coordinated arrangement of positioning holes 8, pins 9, and a mesh plate 10, a mesh plate 10 can be detachably connected to the surface of the drain 4. The mesh plate 10 is made of corrosion-resistant plastic. Simulating real-world usage environments (such as hair and debris accumulation), the device tests the performance of the drain 4 under different levels of clogging. The mesh plate can be easily removed for cleaning or replacement. This allows the device to not only test the drainage volume under clean conditions but also evaluate anti-clogging performance, more closely reflecting real-world application scenarios.
