Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy cofferdam construction equipment, in particular to a water retaining device for water conservancy cofferdam construction. Background Art

[0002] At present, in order to build hydraulic structures in the form of water conservancy hubs on rivers, cities must first treat the foundations of the buildings. However, it is difficult to carry out large-scale basic treatment and construction of hydraulic structures in flowing water, so it is necessary to form a foundation pit and drain the water. The commonly used method is to use a temporary water retaining building cofferdam to isolate all or part of the building foundation pit from the riverbed, and then drain the water for construction. In the construction of hydraulic cofferdams, the piles at the bottom of the cofferdam are usually used to insert into the soil at the bottom of the water area. The function of these piles is to fix the water retaining plate to keep it stable during the construction process. At the same time, the piles can also play a role in supporting and dispersing the load, ensuring that the water retaining plate will not be displaced or broken when subjected to water pressure and soil pressure.

[0003] Since each pile head needs to be installed separately, the whole construction process will become relatively slow. Therefore, the utility model designs a water retaining device for water conservancy cofferdam construction. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0028] like Figure 1-7 As shown, the utility model proposes a water retaining device for water conservancy cofferdam construction, including a pair of main baffles 1, and also including: a pair of secondary baffles 2 movably spliced ​​on both sides of the main baffle 1, the connection between the main baffle 1 and the secondary baffle 2 is fixedly connected by a plurality of connecting members 24 arranged linearly up and down, and the interior of the secondary baffle 2 is provided with a lifting rod 22 for lifting, and the bottom end of the lifting rod 22 is fixedly connected with a conical plug 23 for preventing the lifting rod 22 from tilting after being inserted into the mud of the water area, and the friction between the conical plug 23 and the soil is relatively large, especially when the soil is relatively wet or sticky, the friction is greater. This makes it difficult to pull out the conical plug 23, thereby making the main baffle 1 and the secondary baffle 2 more stable when erected. The main baffle 1 is provided with a lifting mechanism inside for simultaneously inserting the bottom ends of the lifting rods 22 in the secondary baffles 2 on both sides into the mud of the water area; a connecting mechanism movably installed in the middle of the main baffle 1 for enabling a pair of lifting mechanisms on the main baffles 1 to move up and down in linkage; and a transmission mechanism arranged on the main baffle 1 for driving the lifting mechanism to start so that all the lifting rods 22 move upward at the same time.

[0029] Furthermore, the lifting mechanism includes a threaded rod 12 rotatably connected to the main baffle 1, a first bevel gear 13 is fixedly sleeved on the top of the threaded rod 12, a first lifting groove 15 is provided on the side surface where the main baffle 1 is connected to the secondary baffle 2, and a second lifting groove 21 is provided on the side surface where the secondary baffle 2 is connected to the main baffle 1, which overlaps with each other. The first lifting groove 15 and the second lifting groove 21 are used to limit the lifting height of the lifting mechanism. The first lifting groove 15 and the second lifting groove 21 are both provided with an arc push rod 14 spirally connected to the threaded rod 12 in the main baffle 1, and the lower surface of the arc push rod 14 is fixedly connected to the top of a pair of lifting rods 22.

[0030] The connection mechanism includes a connection handle 3, and a return spring 31 is arranged inside the connection handle 3. The function of the return spring 31 is to allow a pair of connection clamping rods 32 to be easily inserted into or removed from a pair of rectangular grooves 47. The two ends of the connection handle 3 are movably connected with the connection clamping rods 32, and the two ends of the return spring 31 are fixedly connected to the ends of the connection clamping rods 32 in the connection handle 3.

[0031] Furthermore, the main baffle 1 is provided with a mounting groove 11, and the transmission mechanism includes a support box 4 connected to the main baffle 1 and fixedly connected to the mounting groove 11. The open end of the support box 4 away from the mounting groove 11 is rotatably connected to a box door 41 through a hinge, and a support block 42 is fixedly connected inside the support box 4. The function of the support block 42 is to make the support rotating rod 44 more stable during the rotation process. The support block 42 is rotatably connected to the support rotating rod 44, and one end of the support rotating rod 44 is fixedly connected to a rotating block 43. The end of the rotating block 43 close to the box door 41 is provided with a hexagonal groove, and the function of the hexagonal groove is to allow some tools to be inserted and rotate the rotating block 43; the other end of the support rotating rod 44 is fixedly connected to a second bevel gear 45 meshing with the first bevel gear 13, and the second bevel gear 45 and the first bevel gear 13 are bevel gears, and the bevel gear is a gear transmission device, which is mainly used to transmit power and motion. It consists of two or more gears, one of which has a beveled tooth surface, and the other gear has a beveled tooth surface meshing with the bevel of the bevel gear. The second bevel gears 45 are fixedly connected with a rotating connection block 46 , and the rotating connection block 46 is provided with a rectangular groove 47 for the end of the connecting rod 32 to be inserted. The function of the rectangular groove 47 is to prevent the connecting rod 32 from rotating after being inserted.

[0032] In this embodiment, when the cofferdam construction needs to use a water retaining device, such as Figure 1As shown, after the main baffle 1 and the secondary baffle 2 are fixedly assembled by the connecting piece 24, the connecting clamps 32 on both ends of the connecting handle 3 are respectively inserted into the rectangular grooves 47 on the ends of a pair of rotating connecting blocks 46 through the return springs 31 in the connecting handle 3, so that the transmission mechanisms on the pair of main baffles 1 can be connected. Then, the box door 41 on the open end of the support box 4 is rotated upward to open, and a tool is inserted into the hexagonal groove on the rotating block 43, and then the rotating block 43 is rotated to drive the support rotating rod 44, the second bevel gear 45 and the connecting mechanism to rotate through the support block 42 in turn. The connecting mechanism drives another second bevel gear 45 to rotate. Since the second bevel gear 45 is meshingly connected with the first bevel gear 13, a pair of second bevel gears 45 drives the corresponding first bevel gear 13 to rotate, and the first bevel gear 13 drives the threaded rod 12 to rotate inside the main baffle 1. Since the threaded rod 12 and the arc push rod 14 are spirally connected, the threaded rod 12 drives the arc push rod 14 and the lifting rod 22 on the lower surface of the arc push rod 14 to rise and fall, and the lifting rod 22 drives the conical plug block 23 at its bottom to rise and fall and insert into the soil at the bottom of the water area, thereby completing the rapid installation of the main baffle 1 and the secondary baffle 2 in the water area.
