Description

Technical Field

[0001] The present application relates to the technical field of water conservancy projects, and in particular to a temporary protective device for reservoir construction. Background Art

[0002] Reservoirs are generally hydraulic engineering structures used to intercept floods, store water and regulate water flow. They refer to artificial lakes formed by building dams at the mouths of ravines or water flows. After the reservoir is built, it can play a role in flood control, water storage for irrigation, water supply, power generation and fish farming.

[0003] During the construction of a reservoir, temporary protective measures are usually required to block the water flow in order to ensure the safety of the construction area. In the related technology, stacking sandbags is one of the commonly used protective measures. In order to prevent the water from flooding into the construction area, the staff will carry the sandbags to the outer edge of the construction area and pile them up to form an interception line. The problem with the related technology is that the sandbags themselves are heavy, and the number of sandbags required for temporary protection is large, which requires the staff to carry them repeatedly, resulting in problems such as excessive labor costs and low protection effects. Summary of the invention

[0004] In order to save manpower and improve the protection effect, the present application provides a temporary protection device for reservoir construction.

Inflating the airbag can make the water retaining plate stand up, thereby intercepting the water flow. The airbag and the base plate are connected by a quick-release structure, which can realize the rapid disassembly and assembly of the airbag. Compared with the existing sandbag stacking method, the protection unit has a simple structure, is easy to install and has a high protection effect.

[0008] Optionally, a second connecting portion is integrally formed on the surface of the airbag, and the second connecting portion extends horizontally along the surface of the substrate and is arranged in cooperation with a quick-release structure. The quick-release structure includes an upper clamping portion and a lower clamping portion spaced apart from each other, and a clamping groove is formed between the upper clamping portion and the lower clamping portion for the second connecting portion to penetrate.

[0009] By adopting the above technical solution, the second connecting part extends to between the upper pressing part and the lower pressing part, and the two can press the second connecting part, thereby increasing the friction between the second connecting part and the upper pressing part and the lower pressing part, thereby ensuring that the second connecting part can be firmly installed on the substrate, that is, ensuring the connection effect between the airbag and the substrate.

[0010] Optionally, the quick-release structure further includes a limit assembly, which is arranged on the surface of the substrate and is in two groups. The two groups of limit assemblies are respectively arranged at both ends of the upper clamping part. Transmission parts are arranged at both ends of the upper clamping part.

[0016] Optionally, one end of the pawl away from the wheel body is rotatably mounted on a support seat, and an elastic reset member and an unlocking member that cooperate with the pawl are also installed on the support seat. The pawl can be separated from the ratchet wheel by pulling the unlocking member.

[0017] By adopting the above technical solution, the setting of the unlocking member can facilitate the construction personnel to apply external force to the pawl away from the wheel body, so that the pawl is separated from the ratchet part, and the wheel body can rotate freely at this time, so as to facilitate the construction personnel to remove the airbag from the base plate after use. The setting of the elastic reset member is used to drive the pawl to reset to cooperate with the ratchet part after the external force on the unlocking member disappears, so as to limit the rotation direction of the wheel body again.

[0018] Optionally, resistance ridges are formed on one side of the upper pressing plate and the lower pressing plate facing the first connecting portion, and the resistance ridges are in the shape of long strips and extend horizontally along the length direction of the base plate.

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-6 This application is described in further detail.

[0037] Example 1

[0038] The present application embodiment discloses a temporary protection device for reservoir construction. Figure 1 A reservoir is a public temporary protection device including several protection units connected to each other on the left and right. The multiple protection units are arranged at the outer edge of the construction area to prevent water from entering the construction area, thereby playing a temporary protection role. Specifically, each protection unit has three core components: a base plate 1, an air bag 2 and a water retaining plate 3.

[0039] The base plate 1 is laid on the foundation surface as the supporting foundation of the entire protection unit. It is understandable that a fixed structure, such as a ground nail, should be provided between the base plate 1 and the foundation surface, and the ground nail is inserted through the base plate 1 into the foundation surface so that the base plate 1 is firmly installed on the foundation surface. The airbag 2 and the water retaining plate 3 are both provided on the base plate 1, wherein the airbag 2 is connected to the base plate 1, and the water retaining plate 3 is connected to the airbag 2, thereby forming a structure that can drive the water retaining plate 3 to rotate in a plane perpendicular to the base plate 1 when the airbag 2 is inflated.

[0040] Reference Figure 2 The airbag 2 and the water retaining plate 3 are specifically connected in the following manner: a first connection portion 5 is formed on the surface of the airbag 2, and an embedding groove is formed between the first connection portion 5 and the airbag 2. One end of the water retaining plate 3 is designed to extend into the embedding groove to achieve a tight connection with the airbag 2. In order to further ensure the connection stability between the water retaining plate 3 and the airbag 2, the protection unit is also equipped with a connection component 6.

[0041] The connection assembly 6 includes a pressure plate 61 disposed on the side of the first connection portion 5 facing away from the airbag 2, and a fastener 62 for connecting the pressure plate 61, the first connection portion 5 and the water retaining plate 3. Through connection holes are provided at corresponding positions of the pressure plate 61, the first connection portion 5 and the water retaining plate 3. When one end of the water retaining plate 3 extends into the embedding groove, these connection holes are aligned. The fastener 62 only needs to be screwed into the connection hole to achieve a firm connection between the water retaining plate 3 and the airbag 2. It can be understood that the connection hole is a threaded hole and the fastener 62 is a bolt.

[0042] Reference Figure 5 and Figure 6, the following connection method is specifically adopted between the airbag 2 and the substrate 1: a second connection part 7 extending horizontally along the surface of the substrate 1 is formed on one side of the airbag 2, and a quick-installation structure 4 matching the second connection part 7 is provided on the substrate 1. The quick-installation structure 4 includes an upper pressing part 41 and a lower pressing part 42, and the upper pressing part 41 and the lower pressing part 42 are arranged at a certain distance to form a pressing groove, and the second connection part 7 can be horizontally extended into the pressing groove, and at least one of the upper pressing plate and the lower pressing plate applies pressure to the second connection part 7, so as to achieve rapid fixation of the airbag 2. Preferably, resistance convex ribs 9 are respectively provided on the upper pressing part 41 and the lower pressing part 42 facing the pressing groove. According to actual needs, the resistance convex ribs 9 should have a specific structure to be able to increase the friction between the second connection part 7 and the upper pressing part 41 and the lower pressing part 42, so as to improve the installation stability of the airbag 2. Specifically, the resistance convex ribs 9 are arranged in a strip shape and extend horizontally along the length direction of the substrate 1.

[0043] In order to further enhance the stability and safety of the quick-install structure 4, a limit assembly 43 is also introduced in this embodiment. These limit assemblies 43 are arranged on the surface of the substrate 1, and the number is preferably two groups, and the two groups of limit assemblies 43 are respectively located at the two ends of the upper clamping part 41. Transmission members 411 are provided at both ends of the upper clamping part 41, and the transmission members 411 extend to the limit assemblies 43 and cooperate with each other. The setting of the limit assembly 43 can limit the movement of the upper clamping part 41 away from the lower clamping part 42, thereby ensuring that the clamping groove continuously and stably clamps the second connecting part 7.

[0044] Reference Figure 3 and Figure 4 , support seats 8 are provided on both sides of the base plate 1, and are used to provide support for two sets of limit assemblies 43 respectively. The limit assembly 43 includes a wheel body 431 rotatably mounted on the support seat 8, a first straight tooth portion 4311 is provided on the side of the wheel body 431, and a transmission member 411 is correspondingly provided on a side of the wheel body 431 close to the first straight tooth portion 4311, and extends in the vertical direction. A second straight tooth portion 4111 matched with the first straight tooth portion 4311 is provided on a side of the transmission member 411 facing the wheel body 431. With the above structure, when downward pressure is applied to the upper pressing portion 41, the transmission member 411 can slide downward in the vertical direction, and at the same time drive the wheel body 431 to rotate through the second straight tooth portion 4111 and the first straight tooth portion 4311.

[0045] Furthermore, the limiting assembly 43 also includes a ratchet portion 4312 formed on the side of the wheel body 431, and a pawl 432 rotatably mounted on the support seat 8. When the pawl 432 is engaged with the ratchet portion 4312, the wheel body 431 can be effectively restricted from rotating in a specified direction, thereby ensuring the stability of the entire quick-install structure 4. Specifically, the setting of the pawl 432 should satisfy that when downward pressure is applied to the upper clamping portion 41, the wheel body 431 can rotate with the descent of the transmission member 411, and will not rotate in the opposite direction. Thereby, the position of the upper clamping portion 41 can be stabilized to ensure that the second connecting portion 7 is clamped and fixed.

[0046] Furthermore, in order to facilitate the release of the restriction of the pawl 432 on the wheel body 431 when necessary, an elastic reset member 433 and an unlocking member 434 that cooperate with the pawl 432 are installed on the support seat 8. Under normal circumstances, the elastic reset member 433 applies an external force toward the wheel body 431 to the pawl 432 to ensure that the pawl 432 and the ratchet part 4312 are tightly engaged; when unlocking is required, the pawl 432 can be rotated away from the wheel body 431 by simply pulling the unlocking member 434, so as to separate the pawl 432 from the ratchet part 4312, and then the wheel body 431 can rotate freely, so that the upper clamping part 41 can move upward, so as to facilitate the second connecting part 7 to be separated from the clamping groove.

[0047] Specifically, the elastic reset member 433 is a spring mounted on the support seat 8 and connected to the pawl 432. Figure 2 In the structure shown, the staff can apply an upward pulling force to the unlocking member 434 to make the end of the pawl 432 close to the wheel body 431 rotate upward, so that it can be separated from the ratchet portion 4312. At this time, the elastic reset member 433 is compressed; when the pulling force applied to the unlocking member 434 disappears, the elastic reset member 433 restores its deformation to restore the pawl 432 to its original position, thereby limiting the rotation direction of the wheel body 431.

[0048] In addition, in order to improve the limiting effect, the limiting components 43 are preferably provided with two groups, and the two groups of limiting components 43 are symmetrically distributed along the center line of the transmission member 411. When the transmission member 411 moves up and down, it can drive the wheels 431 of the two groups of limiting components 43 to rotate synchronously in opposite directions. The ratchet pawls 432 of the two groups of limiting components 43 can respectively limit the rotation of the two wheels 431, thereby improving the limiting effect of the transmission member 411.

[0049] Example 2

[0050] Based on Example 1, this example further optimizes the water retaining plate 3. Figure 5An auxiliary support rod 10 is provided between the water retaining plate 3 and the base plate 1 to improve the connection effect between the water retaining plate 3 and the base plate 1. In addition, a corresponding receiving groove is provided on the surface of the base plate 1. The receiving groove and the auxiliary support rod 10 are in the same vertical plane. One end of the auxiliary support rod 10 away from the water retaining plate 3 extends into the receiving groove. A plurality of clamping parts 11 are provided in the receiving groove. The plurality of clamping parts 11 extend along the length direction of the receiving groove. A clamping groove 12 is formed between two adjacent clamping parts 11. When one end of the auxiliary support rod 10 extends into the receiving groove, it can be exactly located in the clamping groove 12. The position of the auxiliary support rod 10 is fixed by the clamping parts 11 on the front and rear sides, thereby achieving stable support for the water retaining plate 3. Such a design not only enhances the stability of the water retaining plate 3, but also can flexibly adjust its position in the receiving groove according to the inclination angle of the water retaining plate 3.

[0051] Finally, the two opposite surfaces of the water retaining plate 3 are the back surface and the front surface, the airbag 2 and the auxiliary support rod 10 are arranged between the back surface of the water retaining plate 3 and the base plate 1, and the guide ribs 13 are added on the front surface of the water retaining plate 3. These guide ribs 13 are distributed perpendicular to the front surface and are arranged at intervals along the length direction of the water retaining plate 3. The presence of multiple guide ribs 13 can effectively guide the water flow, reduce the impact pressure of the water flow on the water retaining plate 3, and thus extend the service life of the water retaining plate 3.

[0052] The implementation principle of a temporary protective device for reservoir construction in the embodiment of the present application is as follows: First, the construction personnel need to pre-lay the substrate 1 on the base surface to ensure that the substrate 1 is flat and stable. Then, the airbag 2 is quickly fixed on the substrate 1 using the quick-install structure 4. In this process, the construction personnel only need to align the second connecting portion 7 of the airbag 2 with the clamping groove formed by the upper clamping portion 41 and the lower clamping portion 42, and then press the upper clamping portion 41 downward until the second connecting portion 7 is fastened in the clamping groove. Since the water retaining plate 3 and the airbag 2 are connected as one through the connecting component 6, the airbag 2 can be directly inflated after the airbag 2 is fixed, and the water retaining plate 3 is driven to rotate to an inclined state to intercept the water flow at the outer edge of the construction area. In order to further enhance the stability of the water retaining plate 3, the construction personnel adjust the angle and position of the auxiliary support rod 10 according to the actual situation on site, so that the end away from the water retaining plate 3 can be firmly inserted into the clamping groove 12 in the receiving groove. Finally, the construction personnel need to conduct a comprehensive inspection of the entire protection unit to ensure that all components have been correctly installed and are secure.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
