Description

Technical Field

[0001] The present invention relates to the technical field of flood control enclosure installation, and in particular to a device and method for quickly installing flood control enclosures at subway stations. Background Art

[0002] Subways are high-speed, high-capacity, electric-powered rail transit systems built in cities. During heavy rainfall seasons, subway stations, due to their low terrain, easily allow rainwater to flow into them. With this influx of rainwater, drainage equipment is often overloaded and unable to drain the water immediately, causing rainwater to accumulate in the stations, disrupting travel and causing economic losses.

[0003] At present, in order to prevent subway flooding disasters caused by heavy rain, flood prevention fences are often used to block water. An installation groove is set at the bottom of the channel, and the water retaining plate is raised from the ground by electric lifting to form a barrier in the channel. However, when water flows into the installation groove, if a power outage occurs, the water retaining plate cannot be raised, affecting the rapid response of flood prevention work. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a quick installation device for flood control barriers at subway stations, thereby solving the defect of the prior art flood control barriers being dependent on electricity.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A quick installation device for flood prevention enclosures at subway stations includes a channel, with cylinders fixedly connected on both sides of the channel, each cylinder being slidably connected to a baffle, and a support plate provided on the side wall of the channel for supporting the baffle, a sealing rubber plate fixedly connected to the bottom of the baffle, a side plate provided on the lower side of the baffle, the side plate being rotatably connected to a support block, the support block being provided with a through hole, and a limiting telescopic rod being able to be inserted between the through holes of the two support blocks.

[0007] Preferably, the position-limiting telescopic rod comprises two sleeves threadedly connected to each other, a round rod is slidably connected in each sleeve, and a socket is provided on the side wall of the channel, and the round rod can be inserted into the socket.

[0008] Preferably, the sleeve is provided with a slot.

[0009] Preferably, an arc-shaped groove is provided on the upper side of the sealing rubber plate, and the arc-shaped groove is provided corresponding to the limiting telescopic rod.

[0010] Preferably, an embedded box is provided on the inner wall of the channel, the jack is provided on one side of the embedded box, a sealing sleeve is provided in the jack, a protruding groove is provided on the side of the embedded box close to the cylinder, a sealing plate is slidably connected in the protruding groove, an eccentric hole is provided at the lower end of the sealing plate, one end of the round rod is tapered, and the tapered end of the round rod is inserted into the eccentric hole so that the sealing plate slides toward the cylinder;

[0011] A vertical sliding groove is provided at the lower part of the side surface of the baffle, and the side plate is slidably connected in the vertical sliding groove.

[0012] Preferably, an offset groove is provided at one opposite end of the two baffles, and a sealing strip is provided in the offset groove.

[0013] The present invention also discloses a method for quickly installing a flood prevention enclosure at a subway station, comprising the following steps:

[0014] Step 1: Monitor rising water levels outside subway stations.

[0015] Step 2: Unlock the baffles and push them to tilt relative to the channel. Pull out the round rod between the through holes of the support blocks of the two baffles, and thread the two sleeves together to form a limited telescopic rod.

[0016] Step 3: Push the baffle and cooperate with the extension and retraction of the limiting telescopic rod to make the round rod gradually pass through the through hole, and use the limiting telescopic rod as a reference to pull the two baffles to gradually become flush.

[0017] Step 4: When the two baffles are flush, the round rod of the limit telescopic rod is further extended into the socket on the side wall of the channel to complete the quick installation.

[0018] The present invention provides a rapid installation device for flood prevention enclosures at subway stations. By rotating two baffles, a round rod is pulled out of a through hole, and the rotation of a support block is coordinated so that the two sleeves can be coaxially threadedly connected to form a limiting telescopic rod. The two baffles are conveniently pulled simultaneously by the limiting telescopic rod, so that the two baffles are gradually aligned. The round rod can continue to slide and be pulled out relative to the sleeve, and the round rod is inserted into a socket set in the side wall of the channel to form a bolt connection with the two baffles, so that the two baffles are quickly formed into a whole, so that the two split baffles can be combined to form a water retaining structure and still ensure water retaining strength, thereby overcoming the defect of the prior art that electric power control is required.

[0019] The present invention inserts the round rod into the jack and then into the eccentric hole. The eccentric hole needs to move downward and toward the cylinder to be coaxial with the round rod. The round rod is pushed into the eccentric hole so that the eccentric hole gradually becomes coaxial with the round rod. On the one hand, a downward pressure seal is further formed on the sealing rubber plate. On the other hand, the sealing plate contacts and seals the outer side of the shaft sleeve at one end of the baffle, thereby forming a gap between the sealing embedded box and the baffle, which is convenient for rapid installation of the later sealing and water retaining.

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] like Figures 1 to 7 As shown, the present invention provides a rapid installation device for flood prevention enclosures of subway stations, including a channel 1, with cylinders 2 fixedly connected on both sides of the channel 1, each cylinder 2 being slidably connected to a baffle 3, and a support plate 4 being provided on the side wall of the channel 1, the support plate 4 being used to support the baffle 3 and store the baffle 3 on one side of the inner wall of the channel 1, the baffle 3 being made of aluminum alloy and light in weight, so that the baffle 3 will not fall quickly along the cylinder 2, the cylinder 2 being a steel core and a rubber layer being provided on the outer wall, which increases the friction with the rotating hole of the baffle 3, so that the baffle 3 can fall slowly, providing sufficient time for the splicing of the two baffles 3, an offset groove 31 being provided at the opposite end of the two baffles 3, a sealing strip being provided in the offset groove 31, and a seal being formed after the two baffles 3 are aligned, a side plate 6 being provided on the lower part of the side of the baffle 3, the side plate 6 being rotatably connected to the support block 7, the support block 7 being provided with a through hole 71, and a limiting telescopic rod 8 being able to be inserted between the through holes 71 of the two support blocks 7.

[0029] The limiting telescopic rod 8 includes two sleeves 81 threadedly connected to each other, and a round rod 82 is slidably connected inside each sleeve 81. A socket 11 is provided on the side wall of the channel 1, and the round rod 82 can be inserted into the socket 11. A slot 83 is provided on the sleeve 81, and a wrench clamps the slot 83 for twisting and rotating so that the two sleeves 81 are assembled together.

[0030] In Example 1, the baffle 3 is stored on one side of the inner wall of the channel 1. When the water level outside the subway station exceeds the warning line, the two baffles 3 are rotated, and the round rod 82 is pulled out of the through hole 71. Cooperating with the rotation of the support block 7, the two sleeves 81 can be coaxially threaded to form a limiting telescopic rod 8, which is convenient for pulling the two baffles 3 at the same time through the limiting telescopic rod 8, so that the two baffles 3 are gradually flush, and the round rod 82 can continue to slide out relative to the sleeve 81. The round rod 82 is inserted into the socket 11 set on the side wall of the channel 1 to form a bolt connection for the two baffles 3, so that the two baffles 3 are quickly formed into a whole, so that the two split baffles 3 can be combined to form a water retaining structure and still ensure the water retaining strength, thereby overcoming the defect that the existing technology requires electric control.

[0031] Example 2

[0032] like Figures 1 to 7 As shown, the bottom of the baffle 3 is fixedly connected to the sealing rubber plate 5 , and an arc groove 51 is provided on the upper side of the sealing rubber plate 5 , and the arc groove 51 is provided corresponding to the limiting telescopic rod 8 .

[0033] In Example 2, the sealing rubber plate 5 is made of elastic material. When the limiting telescopic rod 8 is squeezed into the arc groove 51, the limiting telescopic rod 8 exerts a downward pressure on the sealing rubber plate 5, and the baffle 3 forms a seal with the ground. On the one hand, a sealed water barrier is formed. On the other hand, the limiting telescopic rod 8 loses the ability to slide freely axially due to squeezing, so that the two split baffles 3 are combined to form a stable water retaining structure.

[0034] Example 3

[0035] like Figures 1 to 7 As shown, an embedded box 12 is provided on the inner wall of the channel 1, and the jack 11 is provided on one side of the embedded box 12. A sealing sleeve is provided in the jack 11 to seal the gap between the round rod 82 and the jack 11. A protruding groove 13 is provided on the side of the embedded box 12 close to the cylinder 2. A sealing plate 14 is slidably connected in the protruding groove 13. There is a gap between the embedded box 12 and the baffle 3, so that the baffle 3 rotates without resistance, thereby facilitating installation. An eccentric hole 15 is provided at the lower end of the sealing plate 14. One end of the round rod 82 is tapered, and the round rod 8 The tapered end of 2 is inserted into the eccentric hole 15 so that the sealing plate 14 slides toward the cylinder 2. The round rod 82 is inserted into a threaded hole at one end of the sleeve 81. The sleeve 81 is provided with an avoidance hole 811. A locking screw is inserted through the avoidance hole 811 and is threadedly connected to the threaded hole, so that the round rod 82 and the sleeve 81 are fixed. The two sleeves 81 are rotated relative to each other. Under the action of the threads, the two sleeves 81 press the round rod 82 into the eccentric hole 15, so that the eccentric hole 15 changes from the initial eccentricity to coaxial with the round rod 82.

[0036] A vertical slide groove 16 is provided at the lower portion of the side surface of the baffle 3 , and the side plate 6 is slidably connected in the vertical slide groove 16 for freely sliding to adapt to the downward pressure sealing effect of the limiting telescopic rod 8 .

[0037] In Example 3, the eccentric hole 15 is originally not coaxial with the round rod 82. When the round rod 82 is inserted into the eccentric hole 15 after being inserted into the socket 11, the eccentric hole 15 needs to move downward and toward the cylinder 2 to be coaxial with the round rod 82. On the one hand, it further forms a downward pressure seal on the sealing rubber plate 5. On the other hand, the sealing plate 14 contacts and seals the outside of the sleeve at one end of the baffle 3, thereby sealing a gap between the embedded box 12 and the baffle 3, which is convenient for the rapid installation of the later sealing and water-blocking.

[0038] The present invention also discloses a method for quickly installing a flood prevention enclosure at a subway station, comprising the following steps:

[0039] Step 1: Monitor the water level outside the subway station. After the water level rises above the warning line, quickly assemble the baffle 3.

[0040] Step 2: Unlock the baffle 3 and push it so that the two baffles 3 are tilted relative to the channel. Pull out the round rod 82 between the through holes 71 of the support blocks 7 of the two baffles, and thread the two sleeves 81 together to form a limiting telescopic rod 8.

[0041] Step 3: Push the baffle 3 and cooperate with the extension and contraction of the limiting telescopic rod 8 so that the round rod 82 gradually passes through the through hole 71, and pull the two baffles 3 gradually flush with each other based on the limiting telescopic rod 8.

[0042] Step 4: When the two baffles 3 are flush, the round rod 82 of the limiting telescopic rod 8 is further extended into the socket 11 set on the side wall of the channel 1 to complete the quick installation. The limiting telescopic rod 8 bolts the two baffles 3 to form a whole, so that the two split baffles 3 are combined to form a water retaining structure and can still ensure the water retaining strength.

[0043] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
