Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hydraulic engineering, in particular to a movable dam for hydraulic engineering. BACKGROUND

[0002] In the field of hydraulic engineering, movable dams have important application value in temporary water storage, flood control and regulation, etc. due to their flexibility. A typical movable dam adopts a flexible rubber dam body structure. The dam body is usually composed of a laying part and an unfolding part, which are folded and rolled up in the initial state. When in use, it is spread on the ground, and the water rising into the space between the laying part and the unfolding part props up the unfolding part into a V-shaped structure by water force, thereby realizing the water blocking function. The water pressure of the unfolded water body acts on the laying part, and the whole structure remains stable through the internal connection relationship of the dam body.

[0003] However, this design scheme has a significant defect in actual application: due to the characteristics of rubber material, the laying part and the unfolding part of the dam body which has been rolled up for a long time are prone to surface adhesion after being unfolded. This adhesion phenomenon will cause the water flow to directly pass over the top of the dam body that has not been unfolded when the water level rises, so that the core unfolding action cannot be triggered, and the dam completely loses the water blocking ability. SUMMARY

[0004] In order to overcome the shortcoming that the movable dam of the prior art cannot be normally unfolded due to the adhesion of the rubber dam body, the present application provides a movable dam for hydraulic engineering.

[0005] The technical scheme of the present application is as follows: a movable dam for hydraulic engineering, comprising a rubber dam body; further comprising a rubber sheet one; the rubber dam body is composed of a laying part and an unfolding part; a plurality of rubber sheet ones are fixedly connected equidistantly between the laying part and the unfolding part; a plurality of groove plates are fixedly connected equidistantly on the laying part of the rubber dam body; each groove plate is located at the side edge of a rubber sheet one; one plug plate is respectively inserted into each groove plate; one stop block is respectively fixedly connected on each plug plate; each stop block is placed on the laying part.

[0006] More preferably, the outer surface of the rubber dam body is coated with a wear-resistant coating.

[0007] More preferably, a plurality of anti-skid protrusions are fixedly connected equidistantly on the lower side of the laying part of the rubber dam body.

[0008] More preferably, a handle is provided on each stop block.

[0009] More preferably, the end of the plug plate facing the groove plate is tapered.

[0010] More preferably, the groove plate is made of flexible material.

[0011] More preferably, the rubber dam body further comprises a plurality of fixed belts fixed on the unfolding part of the rubber dam body.

[0012] More preferably, the rubber dam body further comprises a plurality of connecting blocks slidably connected to each of the stop blocks; each of the connecting blocks is provided with a first flange at a lower portion thereof, and each of the stop blocks is provided with a second flange at an upper portion thereof, the first flange and the second flange being matched to prevent the connecting block from being pulled out; each of the connecting blocks is hollow, and each of the connecting blocks is fixed with a connecting plate therein; each of the connecting plates is fixed with a connecting rod I; each of the connecting rod Is is slidably connected with two mounting plates arranged symmetrically, and each of the mounting plates is provided with a protruding portion at a lower portion thereof; each of the mounting plates is fixed with a spring between the connecting plate and the mounting plate; the spring is sleeved on the connecting rod I; each of the mounting plates is fixed with a connecting rod II at an upper portion thereof; each of the connecting rod IIs is slidably connected with the connecting block; each of the stop blocks is fixed with two clamping blocks arranged symmetrically at inner sides thereof; each of the connecting blocks is fixed with a rope at an upper end thereof; each of the ropes is fixed with a hook I at an end portion thereof; a plurality of hook IIs are fixed on the unfolding part of the rubber dam body; and each of the hooks Is is hung on one of the hook IIs.

[0013] More preferably, the connecting rod II is provided with a pressing disc at a side thereof away from the connecting block.

[0014] More preferably, the rubber dam body further comprises a plurality of rubber sheets II fixed on the unfolding part of the rubber dam body at equal intervals; and each of the rubber sheets II is located between two adjacent rubber sheets I.

[0015] Compared with the prior art, the movable dam of the water conservancy project has the following advantages: 1. After the rubber dam body is laid by artificial, the unfolding part above the slotted plate is lifted by artificial, so as to facilitate operation, then the stop block is held by artificial, and then the insertion plate connected with the stop block is inserted into the slotted plate, and then the unfolded part is placed on the stop block, so that the unfolded part is lifted upward by the stop block to form a gap with the laid part; thus, when the water rises, the water naturally enters between the laid part and the unfolded part, so that the water smoothly lifts and unfolds the unfolded part, and the initial water retaining function of the dam is ensured to be normally started.

[0016] 2. The insertion plate, the rope, the hook I and the hook II are arranged, so that when the water enters between the laid part and the unfolded part, the unfolded part is lifted and moves upward by the rope, and is locked by the clamping block, so that the connecting block protrudes from the stop block to support the unfolded part and keep sufficient gap between the laid part and the unfolded part, and the stable gap formed by the fixing structure is also beneficial to the impurities being smoothly removed with the water flow after the water level decreases, and the siltation is reduced.

DETAILED DESCRIPTION

[0025] It is first to be noted that in the various described embodiments identical parts are provided with identical reference numerals or identical component names, wherein the disclosure contained in the entire description can be transferred by meaning to identical parts provided with identical reference numerals or identical component names. The chosen position indications in the description, for example, upper, lower, lateral, and the like, also refer to the directly described and shown drawings and are transferred by meaning to new positions when the position changes.

[0026] Example 1: A movable dam for water conservancy projects, as shown in Fig. 1, comprises a rubber dam body 1; Figures 1-7

[0027] ​It also includes rubber sheet 2, stop block 3, insert plate 4 and grooved plate 5; the rubber dam body 1 is composed of laying part 101 and unfolding part 102; several rubber sheets 2 are fixedly connected at equal intervals between the laying part 101 and the unfolding part 102; several grooved plates 5 are fixedly connected at equal intervals on the laying part 101 of the rubber dam body 1; each grooved plate 5 is located on the side of a rubber sheet 2; an insert plate 4 is inserted into each grooved plate 5; a stop block 3 is welded onto each insert plate 4; each stop block 3 is placed on the laying part 101.

[0028] To improve the wear resistance of the rubber dam body 1, the outer ring surface of the rubber dam body 1 is coated with a wear-resistant coating, such as a polyurethane coating.

[0029] In order to increase the friction between the laying part 101 and the ground, thereby reducing the risk of the rubber dam body 1 being washed away by water, several anti-slip protrusions are fixedly connected at equal intervals on the lower side of the laying part 101 of the rubber dam body 1.

[0030] To facilitate manual handling of the blocks 3, each block 3 is equipped with a handle.

[0031] To facilitate insertion into the groove of the grooved plate 5, the end of the insert plate 4 facing the grooved plate 5 is set in a conical shape.

[0032] To facilitate the winding of the rubber dam body 1, the grooved plate 5 is made of a flexible material, such as wear-resistant synthetic rubber.

[0033] It also includes fixing straps 6; several fixing straps 6 are fixedly connected to the extended part 102 of the rubber dam body 1.

[0034] In its initial state, the laying section 101 and the unfolding section 102 of the rubber dam 1 are stacked together, and the rubber dam 1 is rolled up and stored. In use, the rubber dam 1 is placed on the ground and manually laid out, with the laying section 101 laid tightly against the ground. When the water rises, water enters between the laying section 101 and the unfolding section 102, lifting and unfolding the unfolding section 102. As the unfolding section 102 unfolds, it straightens the rubber sheet 2, ultimately forming a V-shape. The unfolded section 102 intercepts the water, and the intercepted water exerts downward pressure on the laying section 101. The laying section 101, held in place by the rubber sheet 2, prevents the unfolding section 102 from being washed away, thus achieving the overall water-blocking effect. After the rubber dam 1 is laid out, due to long-term rolling and pressure, the laying section 101 and the unfolding section... The sections 102 and 102 are prone to sticking together, causing water to flow directly over the top of the section 102 instead of between the laying section 101 and the unfolding section 102 when water comes. This prevents the unfolding section 102 from unfolding and thus loses its water-blocking effect. Therefore, after the rubber dam body 1 is laid out manually, the unfolding section 102 located above the grooved plate 5 is lifted up for easier operation. Then, the operator holds the stop block 3 and inserts the insert plate 4 connected to the stop block 3 into the grooved plate 5. The lifted unfolding section 102 is then placed on the stop block 3. With the support of the stop block 3, the unfolding section 102 is pushed upwards, creating a gap between it and the laying section 101. When the water rises, it naturally enters between the laying section 101 and the unfolding section 102, allowing the water to smoothly lift and unfold the unfolding section 102, ensuring that the initial water-blocking function of the dam can be activated normally.

[0035] When the water level drops, the water will no longer support and unfold the unfolding part 102. The unfolding part 102 will fall onto the stop block 3. At this time, there is still a gap between the laying part 101 and the unfolding part 102. Therefore, the impurities (such as sludge) between the laying part 101 and the unfolding part 102 can be washed away manually with water. There is no need to manually lift the unfolding part 102 for washing, which greatly reduces the difficulty of operation. Then, the stop block 3 and the insert plate 4 can be manually pulled out from the grooved plate 5 and removed, and the rubber dam body 1 can be rolled up again.

[0036] Several fixing straps 6 are equidistantly fixed on the extended part 102 of the rubber dam body 1. After the rubber dam body 1 is laid, the fixing straps 6 can be fixed to external fixed points (such as utility poles or trees) by pulling ropes, thereby improving the overall stability of the rubber dam body 1.

[0037] Several anti-slip protrusions are fixed at equal intervals on the lower side of the laying part 101 of the rubber dam body 1, which can increase the friction between the laying part 101 and the ground, thereby reducing the risk of the rubber dam body 1 being washed away by water and improving the overall stability of the rubber dam body 1.

[0038] Example 2: Based on Example 1, as follows Figures 1-7 As shown, it also includes a connecting block 21, a first connecting rod 22, a mounting plate 23, a spring 24, a second connecting rod 25, a locking block 26, a rope 27, a first hook 28, a second hook 29, and a connecting plate 210; each stop 3 is slidably connected to a connecting block 21; each connecting block 21 has a first flange at its lower part and a second flange at its upper part; each connecting block 21 is a hollow structure, and a connecting plate 210 is welded into each connecting block 21; each connecting plate 210 is fixedly connected to a first connecting rod 22; each first connecting rod 22 is slidably connected to two symmetrically arranged mounting plates 23, and each mounting plate 23 has a protrusion at its lower part; each mounting plate 210... A spring 24 is fixed between plate 23 and connecting plate 210; spring 24 is sleeved on connecting rod 1 22; a connecting rod 25 is fixed to the upper part of each mounting plate 23; each connecting rod 25 is slidably connected to connecting block 21; two symmetrically arranged locking blocks 26 are welded to the inner side of each stop block 3; a rope 27 is fixed to the upper end of each connecting block 21; a hook 1 28 is fixed to the end of each rope 27; several hooks 29 are fixed at equal intervals on the unfolding part 102 of the rubber dam body 1; each hook 1 28 is hung on a hook 29; when the unfolding part 102 unfolds, the connecting block 21 is pulled by the rope 27, hook 1 28 and hook 29.

[0039] To facilitate manual pressing, a pressing plate is provided on the side of the connecting rod 25 away from the connecting block 21.

[0040] It also includes rubber sheet 2 31; several rubber sheets 2 31 are fixedly connected at equal intervals on the unfolded part 102 of the rubber dam body 1; each rubber sheet 2 31 is located between two adjacent rubber sheets 1 2.

[0041] To prevent the rubber dam 1 from being displaced by strong winds before the water rises, the baffle 3 is usually not set very high, typically around ten centimeters. This keeps the overall height of the rubber dam 1 low, reducing the windward area and preventing it from being displaced by strong winds. However, this also reduces the space available for manual cleaning of impurities between the laying section 101 and the unfolding section 102, making it difficult to clean. Therefore, after manually inserting the insert plate 4 connected to the baffle 3 into the grooved plate 5, the manual can then hook the hook 28 at the end of the rope 27 onto the hook 29 in the unfolding section 102. In this way, when water enters the laying section 101... When the unfolding part 102 is extended and supported, it pulls the connecting block 21 upward via the rope 27. The upward movement of the connecting block 21 causes the connecting rod 22, mounting plate 23, spring 24, and connecting rod 25 to move upward. When the protrusion at the bottom of the mounting plate 23 moves upward past the locking block 26, the locking block 26 forces the two symmetrical mounting plates 23 to move towards each other and compress the spring 24. After the mounting plates 23 move above the locking block 26, the two mounting plates 23 move back to their original positions under the action of the spring 24, so that the protrusion at the bottom of the mounting plate 23 is once again directly above the locking block 26. Figure 7 As shown; when the water level drops, the water no longer supports the unfolding part 102. After unfolding, the connecting block 21, connecting rod 1 22, mounting plate 23, spring 24, and connecting rod 25 will descend due to gravity. The mounting plate 23 will descend until its protrusion abuts against the locking block 26, thus keeping the connecting block 21 protruding from the stop block 3. The protruding connecting block 21 supports the unfolding part 102, thus maintaining a sufficient gap between the unfolding part 102 and the laying part 101 for manual cleaning of impurities between the laying part 101 and the unfolding part 102. After rinsing, the two connected rods 25 are pressed down manually. The connected rods 25 drive the two mounting plates 23 to move towards each other, so that the two mounting plates 23 are closer and farther away from the locking block 26. Then the connecting block 21 can be pressed down to re-insert the connecting block 21 into the stop block 3. Finally, the stop block 3 and the insert plate 4 can be manually pulled out of the grooved plate 5 and removed.

[0042] To further prevent the rubber dam body 1 from being displaced by strong winds before the water level rises, several rubber sheets 2 31 are installed on the extended part 102 of the rubber dam body 1. Each rubber sheet 2 31 is located between two adjacent rubber sheets 1 2. After the block 3 supports the extended part 102, under the gravity of the rubber sheet 2 31, the part of the extended part 102 located between two adjacent block 3 will bend downwards and sag. It should be noted that after sag, there is still a gap between the extended part 102 and the laying part 101. This further reduces the windward area of ​​the rubber dam body 1 and prevents the rubber dam body 1 from being displaced by strong winds.
