Description

Technical Field

[0001] This utility model relates to the field of floor drain technology, and more specifically, to a concealed floor drain for use on roofs. Background Technology

[0002] Floor drains, as a common drainage structure, are generally used in indoor or roof locations to effectively discharge water outwards. Among them, concealed floor drains not only have drainage functions but also improve their concealment, making the indoor or roof more aesthetically pleasing.

[0003] Publication number CN222362603U discloses a concealed floor drain, the technical solution of which includes a floor drain plate and a floor drain pipe. The floor drain plate is provided with a concealed component. The concealed component includes a sliding plate that slides within the floor drain plate. A support spring is installed in the middle part of the bottom of the plate. Four filter plates and a sliding rod are also fixed to the bottom of the plate. The floor drain plate is not provided with a support plate. The filter plates and the sliding rod slide within the support plate. Both the filter plates and the support plate are provided with a number of filter holes.

[0004] The above technical solution, when using a floor drain, can cover the opening at the top of the floor drain by setting up a cover plate, thereby achieving the effect of hiding the floor drain. When it rains, the cover plate guides the rainwater into the chute, and the filter plate in the chute filters the impurities in the rainwater. At the same time, the filtered rainwater is discharged outward, thereby achieving the effect of draining water from the floor drain.

[0005] However, with the above-mentioned technical solution, the drain is affected by the plate, which prevents rainwater from being discharged directly through the opening at the top of the drain. Instead, it can only flow into the drain through the chute, which reduces the flow rate of rainwater when it enters the drain and affects the drainage efficiency of the drain.

[0006] Therefore, a new solution is needed to address this problem. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a concealed floor drain for roofing, which solves the problem that when the floor drain is draining water, the water can only flow into the floor drain through the chute, which leads to a decrease in the flow rate of rainwater when it enters the floor drain and affects the drainage efficiency of the floor drain.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a concealed floor drain for roofing, comprising a floor drain body and a mounting plate, wherein an installation ring is detachably connected to the inner wall of the floor drain body, the mounting plate and the floor drain body are slidably connected, a fixing net is fixedly connected to the inner wall of the installation ring, a plurality of limiting blocks are fixedly connected to the fixing net, a plurality of through slots for the limiting blocks to be inserted into the mounting plate, and a driving component for driving itself to rise and fall on the mounting plate.

[0009] By adopting the above technical solution, when the floor drain is draining, rainwater will collect above the panel. The driving component will drive the panel upward, simultaneously causing the limiting block and the through groove to separate, thus opening the top of the floor drain body. At this time, the rainwater above the panel will enter between the panel and the fixing net through the through groove, and then flow into the floor drain body through the fixing net, thereby achieving the effect of draining the floor drain. After the floor drain has finished draining, the driving component will drive the panel back to its original position, causing the limiting block to insert into the through groove. At this time, the top of the floor drain body will be closed, and the panel will be protected from the through groove due to the influence of the limiting block, improving the concealment of the floor drain. Through the setting of the limiting block and the through groove, rainwater can be discharged through the opening at the top of the floor drain body during drainage, increasing the drainage volume and improving the drainage efficiency.

[0010] The present invention is further configured such that: the driving component includes a groove formed on the mounting ring, a movable ring is slidably connected in the groove, a buoyancy plate is fixedly connected on the movable ring, the buoyancy plate and the mounting plate are fixedly connected, the buoyancy plate has a through hole that communicates with the through groove, and there is a gap between the mounting plate and the groove.

[0011] By adopting the above technical solution, when rainwater comes into contact with the panel, it flows towards the gap between the panel and the chute, and falls into the chute through the gap, causing the rainwater to accumulate in the chute. When the rainwater accumulates to contact the buoyancy plate, the buoyancy plate is affected by the buoyancy of the rainwater and begins to move upward, driving the panel to move in the same direction. At the same time, it drives the limiting block to separate from the through groove and through hole, thereby opening the opening at the top of the drain body and draining the rainwater on the panel. After the drainage is completed, the buoyancy plate, no longer restricted by the rainwater, begins to drive the panel back to its original position and causes the limiting block to insert into the through groove, thus achieving the effect of driving the panel.

[0012] The present invention is further configured such that: a limiting block is fixedly connected to the inner wall of the moving ring, and a limiting groove is provided on the side wall of the sliding groove for the limiting block to slide.

[0013] By adopting the above technical solution, it is possible to prevent the moving ring and the slide from separating when the plate moves, thus avoiding affecting the normal use of the plate. At the same time, it can also prevent the plate from shifting position, making it easier for the plate to return to its original position.

[0014] The present invention is further configured such that a plurality of seepage holes are provided at the bottom of the chute.

[0015] By adopting the above technical solution, the rainwater remaining in the chute can be discharged into the drain body, thereby improving the drainage effect of the drain.

[0016] The present invention is further configured such that: an annular groove for placing an installation ring is provided on the drain body, a locking block is fixedly connected to the side wall of the installation ring, and a locking groove for the locking block to engage is provided on the side wall of the annular groove.

[0017] By adopting the above technical solution, users can easily disassemble the mounting ring and the drain body, making it convenient to clean impurities inside the drain body and on the mounting ring, thus preventing the drain from becoming clogged.

[0018] The present invention is further configured such that a filter screen is placed inside the drain body.

[0019] By adopting the above technical solution, impurities in rainwater can be effectively screened out, preventing floor drains from becoming clogged.

[0020] The present invention is further configured such that the longitudinal section of the filter screen is arranged in a downward arc shape.

[0021] By adopting the above technical solutions, the filter's capacity to hold impurities can be increased, reducing the frequency of cleaning by the user.

[0022] In summary, this utility model has the following beneficial effects: When the floor drain is draining water, the driving component separates the limiting block and the through groove, thereby opening the top of the floor drain body. At this time, rainwater flows into the floor drain body through the through groove, thus achieving the effect of draining water. After the floor drain has finished draining, the driving component drives the plate back to its original position, causing the limiting block to insert into the through groove. At this time, the top of the floor drain body is closed, and the plate is affected by the limiting block, which can prevent the through groove on the plate from being exposed, improving the concealment of the floor drain. Through the setting of the limiting block and the through groove, rainwater can be discharged through the opening at the top of the floor drain body during drainage, increasing the drainage volume of the floor drain and improving drainage efficiency.

[0030] A concealed floor drain used in roofs, such as Figures 1-3As shown, the drain includes a drain body 1 and a mounting plate 2. A mounting ring 3 is detachably connected to the inner wall of the drain body 1. The mounting plate 2 and the drain body 1 are slidably connected. A fixing net 4 is fixedly connected to the inner wall of the mounting ring 3. Several limiting blocks 5 are fixedly connected to the fixing net 4. The mounting plate 2 has several through slots 6 for the limiting blocks 5 to insert into. The mounting plate 2 is equipped with a driving component for lifting itself. When the drain is draining water, rainwater will collect above the mounting plate 2. The driving component will drive the mounting plate 2 upwards, simultaneously causing the limiting blocks 5 and the through slots 6 to separate, thus opening the top of the drain body 1. At this time, the rainwater above the mounting plate 2 will flow through... The water flows through the groove 6 between the plate 2 and the fixing net 4, and the fixing net 4 directs the rainwater into the drain body 1, thus achieving the effect of draining the drain. After the drain has finished draining, the plate 2 is driven back to its original position by the drive component, so that the limiting block 5 is inserted into the groove 6. At this time, the opening at the top of the drain body 1 is closed, and the groove 6 on the plate 2 is prevented from being exposed due to the influence of the limiting block 5, thus improving the concealment of the drain. With the setting of the limiting block 5 and the groove 6, rainwater can be discharged through the opening at the top of the drain body 1 when the drain is draining, increasing the drainage volume and improving the drainage efficiency.

[0031] like Figure 2 , Figure 3 As shown, the driving component includes a groove 7 formed on the mounting ring 3, a movable ring 8 slidably connected in the groove 7, a buoyancy plate 9 fixedly connected to the movable ring 8, the buoyancy plate 9 and the mounting plate 2 fixedly connected, the buoyancy plate 9 has a through hole 10 that communicates with the through groove 6, and there is a gap between the mounting plate 2 and the groove 7.

[0032] When rainwater comes into contact with the panel 2, it flows towards the gap between the panel 2 and the chute 7, and falls into the chute 7 through the gap, causing the rainwater to accumulate. When the accumulated rainwater comes into contact with the buoyancy plate 9, the buoyancy plate 9 is affected by the buoyancy of the rainwater and begins to move upward, causing the panel 2 to move in the same direction. At the same time, it drives the limiting block 5 to separate from the through groove 6 and the through hole 10, thereby opening the opening at the top of the drain body 1 and allowing the rainwater on the panel 2 to enter. After the discharge is completed, the buoyancy plate 9, no longer restricted by the rainwater, begins to drive the plate 2 back to its original position, and the limiting block 5 is inserted into the through groove 6, thereby achieving the effect of driving the plate 2. The inner wall of the moving ring 8 is fixedly connected to the limiting block 11, and the side wall of the slide groove 7 is provided with a limiting groove 12 for the limiting block 11 to slide. This can prevent the moving ring 8 and the slide groove 7 from separating when the plate 2 moves, thus avoiding affecting the normal use of the plate 2. At the same time, it can also prevent the position of the plate 2 from shifting, making it easier for the plate 2 to return to its original position.

[0033] like Figure 2 , Figure 3As shown, the bottom of the chute 7 is provided with several seepage holes 13, which can drain the rainwater remaining in the chute 7 into the drain body 1, thereby improving the drainage effect of the drain.

[0034] like Figure 2 , Figure 3 As shown, the drain body 1 has an annular groove 14 for placing the installation ring 3. The side wall of the installation ring 3 is fixedly connected to a locking block 15. The side wall of the annular groove 14 has a locking groove 16 for the locking block 15 to engage. This allows the user to easily disassemble the installation ring 3 and the drain body 1, making it easier to clean the impurities inside the drain body 1 and on the installation ring 3, thus preventing the drain from becoming clogged.

[0035] like Figure 2 , Figure 3 As shown: A filter screen 17 is placed inside the drain body 1, which can effectively screen out impurities in rainwater and prevent the drain from becoming clogged. The longitudinal section of the filter screen 17 is set in a downward arc shape, which can increase the load capacity of the filter screen 17 for impurities and reduce the frequency of cleaning by the user.

[0036] The working principle of this utility model is as follows: When the floor drain is draining water, rainwater will collect above the plate 2 and flow towards the gap between the plate 2 and the chute 7. The rainwater will fall into the chute 7 through the gap, causing the rainwater to accumulate in the chute 7. When the rainwater accumulates to contact the buoyancy plate 9, the buoyancy plate 9 will be affected by the buoyancy of the rainwater and begin to move upward, driving the plate 2 to move in the same direction. At the same time, it will drive the limiting block 5 to separate from the through groove 6 and the through hole 10, thereby opening the opening at the top of the floor drain body 1. At this time, the rainwater above the plate 2 will enter between the plate 2 and the fixing net 4 through the through groove 6, and the rainwater will flow into the floor drain body 1 through the fixing net 4, thereby achieving the effect of draining the floor drain.

[0037] After the floor drain finishes draining, the buoyancy plate 9, no longer restricted by rainwater, begins to move the plate 2 back to its original position, causing the limiting block 5 to insert into the through groove 6. At this time, the opening at the top of the floor drain body 1 is closed, and the plate 2, affected by the limiting block 5, can prevent the through groove 6 on the plate 2 from being exposed, thus improving the concealment of the floor drain. Through the setting of the limiting block 5 and the through groove 6, rainwater can be discharged through the opening at the top of the floor drain body 1 when the floor drain is draining, increasing the drainage volume of the floor drain and improving drainage efficiency.

[0038] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
