Description

Technical Field

[0001] The present application relates to the technical field of water conservancy projects, and in particular to an emergency temporary dam for water conservancy projects. Background Art

DETAILED DESCRIPTION

[0017] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0018] The present application embodiment discloses an emergency temporary dam for water conservancy projects. Figure 1 and Figure 2 The emergency temporary dam for water conservancy projects includes a fixing assembly 10, a blocking member 20, at least one group of supporting assemblies 30, a partition frame 40 and a plurality of groups of water-absorbing expansion bags 50.

[0019] The supporting assembly 30 is connected to the fixing assembly 10 and the blocking member 20 respectively, and the position state between the fixing assembly 10 and the blocking member 20 can be changed by using the supporting assembly 30 .

[0020] During flood control, the support assembly 30 can support the blocking member 20 above the fixing assembly 10. The front of the blocking member 20 is formed with an opening communicating with its inner cavity, and the partition frame 40 is fixedly connected to the inner cavity of the blocking member 20 and divides the inner cavity of the blocking member 20 into a plurality of independent cavities, and a group of water-absorbing expansion bags 50 are placed in each group of cavities during flood control, so that the water-absorbing expansion bags 50 absorb water and expand to assist in flood control and water blocking.

[0021] During transportation, the support assembly 30 can support the blocking member 20 to be laid flat on the fixing assembly 10, and the water-absorbing expansion bags 50 can also be stacked and stored in the fixing assembly 10, so that the overall device can reduce the occupied space.

[0022] See also Figure 4The fixing assembly 10 includes a base 11, and the top of the base 11 is fixedly connected with a number of positioning brackets 12 equal to the number of support assemblies 30, and each group of positioning brackets 12 is pivotally connected to the bottom end of the connecting bracket 31 in the adjacent support assembly 30, so that the support assembly 30 can deflect and adjust its position state above the base 11. A supporting step 16 protruding upward is formed on the side of the top of the base 11 away from the positioning bracket 12, and the top of the supporting step 16 is set to be a plane parallel to the horizontal plane, so that the supporting step 16 can be used to assist in supporting and placing the support assembly 30 and the blocking member 20 during transportation. A placement groove 13 is also formed on the base 11, and several groups of water-absorbing expansion bags 50 can be stored in the placement groove 13 when not in use, and the placement groove 13 is covered and pressed by a cover plate 14 hinged on the top of the placement groove 13. A plurality of fixing holes 15 are formed on the base 11 , and the plurality of fixing holes 15 penetrate the base 11 longitudinally, so that when reinforcing the dam, workers can use fixing nails to pass through the fixing holes 15 and insert them into the ground to fix the base 11 .

[0023] In this embodiment, the length of the blocking member 20 is equal to the length of the base 11, so that when multiple groups of emergency temporary embankments for water conservancy projects are installed and used continuously, the blocking members 20 in each group of emergency temporary embankments for water conservancy projects can form a continuous blocking structure. Figure 1 When used for flood prevention, the bottom edge line is coplanar with the bottom plane of the base 11, so that the inclined blocking member 20 can block the water body when used for flood prevention.

[0024] See also Figure 3, the number of support assemblies 30 is set to two groups, and the two groups of support assemblies 30 are symmetrically installed at the two ends of the back of the blocking member 20 along the length direction of the blocking member 20, so that each group of support assemblies 30 can evenly bear the gravity at the blocking member 20 and the pressure of the water body during flood control. The support assembly 30 may include a connecting frame 31, a collar 32, a support pipe 33 and an extension rod 34. The connecting frame 31 is fixedly connected to the back of the blocking member 20 and is pivotally connected to the fixing assembly 10, so that it can drive the blocking member 20 to deflect and adjust its position state. The collar 32 is pivotally connected to the middle gap of the connecting frame 31, and the support pipe 33 is fixedly connected to the outer wall of the collar 32, so that the support pipe 33 can be deflected and placed in the middle gap of the connecting frame 31; the support pipe 33 can also be moved out of the middle gap of the connecting frame 31 and used to support the connecting frame 31. A threaded chamber is formed at one end of the support tube 33 facing away from the collar 32, and one end of the extension rod 34 is screwed into the threaded chamber by means of a threaded connection, and the other end of the extension rod 34 protrudes out of the support tube 33. When the staff screws the extension rod 34 toward the base 11, it can be inserted into the base 11, so that the support assembly 30 and the fixing assembly 10 cooperate with the blocking member 20 to form a triangular support structure. When the staff screws the extension rod 34 away from the base 11, it can be moved out of the base 11, so that the support tube 33 and the extension rod 34 can be moved into the middle gap of the connecting frame 31 for placement.

[0025] In this embodiment, the partition frame 40 includes a plurality of groups of mutually parallel horizontal plates and a plurality of groups of mutually parallel vertical plates, which are fixedly connected to form a grid structure, and the partition frame 40 divides the inner cavity of the blocking member 20 into cavities that match the size of the water-absorbing expansion bag 50. The length and width of each group of cavities in the blocking member 20 are respectively matched with the length and width of the water-absorbing expansion bag 50, and the depth of each group of cavities in the blocking member 20 is greater than the thickness of the water-absorbing expansion bag 50 after absorbing water, so that when used for flood control, a group of water-absorbing expansion bags 50 can be placed in each group of cavities, and the water-absorbing expansion bag 50 can be prevented from falling from the cavity after absorbing water and expanding.

[0026] In this embodiment, the outer skin of the water-absorbing expansion bag 50 is formed by sewing a sack with good water permeability, and the inner bag is made of a water-absorbing material. For example, the inner bag of the common water-absorbing expansion bag 50 is made of super absorbent polymer (SAP), which can quickly expand 80 to 100 times after absorbing water. The water-absorbing expansion bag is a prior art and will not be described in detail here.

[0027] 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.
