Some water retaining devices only rely on their own weight or simple supporting legs for fixation, and lack stability when facing large water flow pressure. Therefore, a building foundation pit water retaining device is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Reference Figure 1 - Figure 3 When the cam 3 is in the upright position, the cam 3 is in the upright position, and the cam 3 is in the upright position, so that the cam 3 can move upwards and downwards, thereby preventing the cam 3 from moving.

[0035] Reference Figure 2 - Figure 4The bottom end of the outer wall of the support seat 5 is fixedly connected to a connecting block 6, and the inner wall of the connecting block 6 is provided with a supporting mechanism 7. The inner wall of the connecting frame 3 is provided with a limiting assembly 8, which includes a handle 81. The bottom end of the outer wall of the handle 81 contacts the surface of the connecting frame 3, and the traction rope 82 is slidably connected to the inner side wall of the connecting frame 3. The inner side of the connecting frame 3 is provided with an empty groove that fits the traction rope 82, so that when the handle 81 is pulled outward, it will drive the traction ropes 82 on both sides to move synchronously, and the guide wheel 83 is rotatably connected to the inner wall of the connecting frame 3. The bottom end of the outer wall of the handle 81 is fixedly connected to two sets of traction ropes 82, and the outer wall of the traction rope 82 contacts the guide wheel 83. The guide wheel 83 is provided to guide the moving position of the traction rope 82 to prevent the traction rope 82 from being easily broken due to wear at the bending part. The end of the traction rope 82 away from the handle 81 is fixedly connected to the plug block 85, and the handle 81 is pulled upward. When the lever 82 is moved, the corresponding plug block 85 is pulled by the traction rope 82 to make the two groups of plug blocks 85 move synchronously to the middle. The plug block 85 is elastically connected to the inner side wall of the connecting frame 3 by the return spring 84. One end of the return spring 84 is fixedly connected to the outer wall of the plug block 85, and the other end of the return spring 84 is fixedly connected to the inner walls of both sides of the connecting frame 3. The function of the return spring 84 is to automatically reset the plug block 85 when the plug block 85 is pulled by the traction rope 82 and moves on the inner wall of the connecting frame 3, so that the traction rope 82 pulls the handle 81 to automatically reset. The plug block 85 is slidably connected to the inner walls on both sides of the connecting frame 3. The inner side wall of the baffle 1 is provided with two sets of through holes, the plug block 85 is plugged into the inner wall of the through hole, and the plugging between the two can move the connecting frame 3 on the inner wall of the baffle 1 to fix the position of the support seat 5 and the hinge rod 4 after expansion and storage.

[0036] Reference Figure 2 and Figure 5 The top of the screw sleeve 71 is provided with an internal thread, and the inner wall of the screw sleeve 71 is provided with an external thread. By providing an internal thread on the inner wall of the connecting block 6, the screw sleeve 71 can move up and down on the inner wall thread of the connecting block 6, so that the screw sleeve 71 can penetrate the connecting block 6 as a whole to enter the soil inside the building foundation pit, thereby increasing the stability of the overall device. The screw sleeve 71 is threadedly connected to the inner wall of the connecting block 6, and the inner wall of the top of the screw sleeve 71 is provided with an internal thread. The inner wall of the top of the screw sleeve 71 is threadedly connected to the threaded rod 72. By providing an internal thread on the top of the screw sleeve 71, the screw rod 72 can push the slider 73 to move on the inner wall of the screw sleeve 71 when the thread is rotated, so that the slider 73 can push the triangular block 74 to descend. The end of the screw rod 72 is rotatably connected to the slider 73. By providing a rotating slider 73, the screw rod 72 does not drive the slider 73 to rotate synchronously when it rotates.

[0037] Reference Figure 5The outer wall of the bottom end of the slider 73 is slidably connected to a triangular block 74, and the inner wall of the triangular block 74 is provided with a sliding groove that fits the bottom end of the slider 73, so that the slider 73 can only move on the inner wall of the triangular block 74 when it moves back and forth. At the same time, because the slider 73 and the triangular block 74 are designed with inclined surfaces, when the slider 73 moves back and forth, it will push the triangular block 74 to drive the connecting rod 75 to move up and down. The bottom end of the outer wall of the triangular block 74 is fixedly connected to the connecting rod 75, and the bottom end of the outer wall of the connecting rod 75 is fixedly connected to the trapezoidal block 76 The outer walls of both sides of the trapezoidal block 76 are slidably connected with contact rods 77. The outer sides of the two groups of contact rods 77 are provided with guide grooves that fit on both sides of the trapezoidal block 76, so that when the trapezoidal block 76 moves up and down following the connecting rod 75, it will push the two groups of contact rods 77 to move outward at the bottom end of the threaded sleeve 71, thereby increasing the contact area of ​​the threaded sleeve 71 as a whole when inserted into the foundation pit soil, thereby increasing its stability. The connecting rod 75 is slidably connected to the inner wall of the threaded sleeve 71, and the two groups of contact rods 77 are slidably connected to the inner wall of the bottom end of the threaded sleeve 71.

[0038] Working principle: First, according to the width of the foundation pit, multiple groups of baffles 1 are quickly spliced ​​vertically through positioning blocks 2 and slide grooves.

[0039] Next, pull the handle 81, and the traction rope 82 will pull the plug 85 toward the middle. At the same time, when the plug 85 moves toward the middle, the reset spring 84 will be elastically compressed. Then, move the connecting frame 3 downward, and the connecting frame 3 drives the hinge rod 4 to descend, so that the support seat 5 can be pushed to expand around its rotation center point through the hinge rod 4, so that it contacts the surface of the foundation pit to form a triangular stable structure. After adjusting the position of the connecting frame 3, release the handle 81, and the plug 85 will be plugged into the through hole on the inner side wall of the baffle 1 under the action of the reset spring 84 to fix the position of the connecting frame 3.

[0040] Finally, rotate the threaded sleeve 71 to insert it into the foundation pit soil, then rotate the threaded rod 72 to push the slider 73 to move, thereby pushing the triangular block 74 to drive the connecting rod 75 to descend. At the same time, the process of the connecting rod 75 descending will also drive the trapezoidal block 76 to descend synchronously, so that the trapezoidal block 76 can push the two sets of contact rods 77 to expand, increase the contact area between the threaded sleeve 71 and the soil, improve the stability of the overall device in the foundation pit, and achieve a water-blocking effect on the building foundation pit.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
