Description

Technical Field

[0001] This utility model relates to the technical field of rainwater runoff interception, specifically to a non-powered vertical rain grate that adjusts its flow rate according to rainfall. Background Technology

[0002] A storm drain grate is a metal barrier typically installed at the drain opening to block debris from the flowing water. Existing storm drain grates often have the following drawbacks in use:

[0003] 1) Existing rain grates are often designed as fixed structures with a constant flow rate. In the event of severe weather conditions such as heavy rain, the fixed flow rate often cannot meet the passage requirements. At the same time, the intercepted dirt and impurities will accumulate at the inlet of the rain grate, further reducing the flow rate of the rain grate.

[0004] 2) Portable storm drains often require an additional power source, and the use of electric drive in stormwater runoff also poses safety risks.

[0005] Therefore, there is an urgent need to provide a solution to address the defects and shortcomings of the existing technologies. Summary of the Invention

[0006] In order to overcome the defects and shortcomings of the existing technology, this utility model provides a non-powered vertical rain grate that adjusts the flow rate according to the rainfall.

[0007] The specific solution provided by this utility model is as follows:

The end of the drive rod away from the horizontal bar is fixed with a collar. The collar is sleeved on the outer periphery of the lifting rod.

[0012] As a further preferred embodiment of the present invention, the transmission component further includes a first guide shaft, a second guide shaft, and a connecting shaft. The first guide shaft and the second guide shaft are fixed inside the frame, and the first guide shaft is located inside the connection position between the horizontal bar and the vertical bar, the second guide shaft is located inside the connection position between the horizontal bar and the drive rod, and the connecting shaft is fixedly connected to the end of the vertical bar away from the horizontal bar and passes through the inside of the buckle.

[0013] As a further preferred embodiment of the present invention, the water-absorbing component includes a water-absorbing body, and a water-absorbing hole for passing through the lifting rod is provided inside the water-absorbing body.

[0036] [First Embodiment]

[0037] like Figure 1-12 The image shown is a non-powered vertical rain grate with adjustable flow rate according to rainfall, provided in the first embodiment of this utility model. Figure 1 As shown, the system includes a frame 1, which can be installed at the desired rainwater runoff interception location. A lifting rod 2 is installed on the top of the frame 1. One end of a transmission component 3 is connected to the lifting rod 2. A water-absorbing component 4 is fixed to the outer periphery of the lifting rod 2. The water-absorbing component 4 can move up and down inside the frame 1 according to its mass change before and after absorbing water. The other end of the transmission component 3 is connected to a latch 5. The top of the grate 6 is rotatably connected to the inside of the frame 1. The latch 5 can unlock or lock the bottom position of the grate 6 under the driving action of the lifting motion of the water-absorbing component 4. By adjusting the working position of the grate, the grate remains locked in the rainless or light rainy weather to achieve the drainage and interception function. In the rainy or stormy weather, the grate remains unlocked and rotates to open to achieve a large flow drainage function. Thus, the grate can adjust the flow rate according to the rainfall, achieving a better interception effect under different rainfall conditions.

[0038] like Figure 2 As shown, the lifting rod 2 in this embodiment includes a rod body 21. Elastic elements 22 are fixed at the bottom of both ends of the rod body 21. One end of the elastic element is fixedly connected to the end of the rod body 21, and the other end is fixedly connected to the inner wall of the frame 1. The elastic element 22 can be a spring or other elastic element commonly used in the mechanical field. By providing the elastic element 22, the water suction element 4 presses and locks the elastic element 22 when it descends. After the descent is completed, the elastic element 22 in the locked state can help the water suction element 4 to rise and reset with its own elastic force. As a priority, the bottom of both ends of the rod body 21 is provided with mounting grooves 23 for accommodating the elastic element 22, so that the elastic element 22 is accommodated inside the mounting groove 23 to further save space and effectively protect the elastic element 22.

[0039] like Figure 3 As shown, the transmission component 3 includes a horizontal bar 31 and a vertical bar 32 connected to each other. The end of the vertical bar 32 away from the horizontal bar 31 is connected to the latch 5. The end of the horizontal bar 31 away from the vertical bar 32 is connected to a drive rod 33. The end of the drive rod 33 away from the horizontal bar 31 is fixed with a collar 34. The collar 34 is sleeved on the outer periphery of the lifting rod 2, thereby transmitting the lifting and lowering movement of the water-absorbing component 4 through the collar 34 to the latch 5 end in sequence via the drive rod 33, the horizontal bar 31 and the vertical bar 32.

[0040] like Figure 4 As shown, the transmission component 3 in this embodiment also includes a first guide shaft 35, a second guide shaft 36, and a connecting shaft. The first guide shaft 35 and the second guide shaft 36 are fixed inside the frame 1. The first guide shaft 35 is located inside the connection position between the horizontal bar 31 and the vertical bar 32, and the second guide shaft 36 is located inside the connection position between the horizontal bar 31 and the drive rod 33. By setting the first guide shaft 35 and the second guide shaft 36, the lifting and lowering movement of the water-absorbing component 4 is transmitted to the locking buckle 5 end to realize the driving action of the locking buckle 5. The connecting shaft is fixedly connected to the end of the vertical bar 32 away from the horizontal bar 31 and passes through the inside of the locking buckle 5. The movement of the vertical bar 32 drives the corresponding movement of the locking buckle 5 through the connecting shaft.

[0041] like Figure 5 As shown, the water-absorbing component 4 in this embodiment includes a water-absorbing body 41, and a water-absorbing hole 42 for passing through the lifting rod 2 is provided inside the water-absorbing body 41. The water-absorbing body 41 is made of water-absorbing material, which is either a sponge or SAP (super absorbent resin). Thus, the water-absorbing component 4 achieves its lifting and lowering movement inside the frame 1 by changing its mass before and after absorbing water.

[0042] like Figure 6As shown, the latch 5 includes a latch body 51. One end of the latch body 51 near the transmission member 3 has a connecting hole 52 for the connecting shaft to pass through. The other end of the latch body 51 is fixed with a connecting part 53 that is movably connected to the frame 1. The latch 5 rotates around the connecting part 53 through the movable connection with the frame 1, thereby realizing the locking or unlocking action of the latch. The bottom of the latch body 51 has a latch part 54 that can lock and engage with the bottom of the grate 6. Preferably, the bottom of the grate 6 is fixed with a limiting shaft 61, and the latch part 54 is set as a semi-circular groove that engages with the limiting shaft 61. The rotational locking of the grate 6 is realized through the corresponding engagement of the latch part 54 and the limiting shaft 61.

[0043] like Figure 7 As shown, in this embodiment, the grate 6 has several baffle shafts 62 fixed inside, and each baffle shaft 62 is fixedly provided with a baffle body 63. The baffle bodies 63 arranged in an alternating manner can effectively intercept the runoff rainwater.

[0044] The specific working process of this embodiment is as follows:

[0045] like Figure 8 and Figure 11 As shown, when there is no rainfall, the elastic elements 22 at the bottom of both sides of the lifting rod 2 keep the lifting rod 2 in a high position. The water absorption element 4 is in a high position in the frame 1 along with the lifting rod 2. At this time, the transmission element 3 connected to the lifting rod 2 is in a relaxed state, and the other end of the transmission element 3, the latch 5, hangs down naturally to lock the bottom of the grate 6.

[0046] like Figure 8 and Figure 11 As shown, in a low rainfall state, rainwater flows through the grate 6. The grate 6 rotates at its upper center due to the impact of the rainwater flow. However, due to the locking restriction of the latch 5, the bottom of the grate 6 cannot rotate. Initially, the rainwater is intercepted through the grate 6.

[0047] like Figure 9-10 As shown in Figure 12, under conditions of heavy rain and torrential rain, the water level gradually rises as the rainwater flows through the frame 1. The rainwater comes into contact with the water-absorbing component 4, and the water-absorbing component 4 absorbs water and becomes heavier until its own weight exceeds the elastic force of the elastic components 22 on both sides of the lifting rod 2. The water-absorbing component 4 drives the lifting rod 2 to move downward, and the lifting rod 2 simultaneously drives the transmission component 3 to open the lock 5 upward. At this time, the grate 6 is unlocked, and the grate 6 rotates around the top of the grate 6 as it is impacted by the water flow, allowing the grate to increase the flow rate for drainage.

[0048] After the rainfall ends, the grate 6 falls back due to gravity. As time goes by, the water inside the absorbent component 4 gradually evaporates, reducing the weight of the absorbent component 4 until its own weight is less than the elastic force of the elastic components 22 on both sides of the lifting rod 2. At this time, the transmission component 3 returns to a relaxed state, and the latch 5 falls naturally to lock the bottom of the grate 6 again.

[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
