DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] Example 1

[0022] like Figure 1-4 As shown, the utility model provides a technical solution: a water conservancy project foundation quality detection device, including a base 100 with a through groove inside, a penetrator 103 with a cavity at the bottom is placed in the through groove of the base 100, the top of the base 100 is fixedly connected to a bracket 101, a counterweight block 200 is arranged inside the bracket 101, and a resistance plate 203 adapted to the penetrator 103 is fixedly connected to the bottom of the counterweight block 200, and a driving component for driving the counterweight block 200 to reciprocate and rise and fall is arranged on the top of the base 100.

[0023] The driving assembly can be provided to facilitate the lifting and lowering of the counterweight 200, thereby reducing the difficulty of the work. The driving assembly includes a rotating rod 300 rotatably connected to the top of the base 100 and located on both sides of the counterweight 200. The two sides of the counterweight 200 are respectively fixedly connected with racks 204. The outer surfaces of the two rotating rods 300 are respectively fixedly connected with incomplete gears 301 meshing with the racks 204. The top of the base 100 and located above the two rotating rods 300 are rotatably connected with a worm 304. The outer surfaces of the two rotating rods 300 are respectively fixedly connected with the incomplete gears 301 meshing with the racks 204. The surfaces are fixedly connected with worm wheels 302, and the two worm wheels 302 are respectively meshed with worms 304. The top of the base 100 is fixedly connected with a reduction motor 303, and the output end of the reduction motor 303 is fixedly connected to the worm 304. By setting up a transmission between the worm 304 and the worm wheel 302, the torque of the rotation of the rotating rod 300 can be increased, so that the counterweight block 200 can move stably. The consistent transmission distance between the incomplete gear 301 and the rack 204 can stably measure the penetration depth of the penetrometer 103 for each standard penetration.

[0024] Among them, in order to further improve the convenience of standard penetration detection, a limit groove 201 is opened inside the counterweight block 200, the top of the bracket 101 is slidably connected to the limit groove 201, and the two ends of the counterweight block 200 are respectively fixedly connected with scales 202, wherein the scale 202 can facilitate the user to check the data of each standard penetration in time.

[0025] Specifically, the position pointed to by the middle scale 202 of the counterweight 200 when the bottom of the interference disk 203 contacts the top of the penetrator 103 for the first time can be recorded, and then the reduction motor 303 can be turned on to drive the worm 304 to rotate, thereby driving the two worm wheels 302 to rotate, thereby driving the two rotating rods 300 to rotate in opposite directions, thereby driving the two incomplete gears 301 to rotate in opposite directions, thereby meshing with the rack 204, thereby driving the counterweight 200 to move upward, thereby driving the interference disk 203 away from the top of the penetrator 103. When the incomplete gear 301 is disengaged from the rack 204, the counterweight 200 is affected by gravity and drives the interference disk 203 to hit the top of the penetrator 103, so that it is forced to move downward and inserted into the soil layer. At this time, the reduction motor 303 can be turned off to calculate the position pointed to by the scale 202 and compare it with the initial position, so as to obtain the depth of the standard penetration of the penetrator 103. By providing a driving component, it is convenient to realize automated standard penetration work and reduce the workload of the staff.

[0026] Furthermore, a plurality of universal wheels 102 are fixedly connected to the bottom of the base 100, screw rods 400 are threadedly connected to both ends of the base 100, ground plugs 402 are fixedly connected to the bottoms of the two screw rods 400, and handles 401 are fixedly connected to the tops of the two screw rods 400.

[0027] In summary, by providing a handle 401, it is convenient for the user to drive the screw 400 to rotate and thereby drive the ground plug 402 to move downward and insert into the soil layer, which can reinforce the position of the base 100, stabilize the base 100 in the desired position, and improve its standard penetration stability. The universal wheel 102 is provided to facilitate moving the base 100 to the desired position, so as to flexibly perform standard penetration on different foundations.

[0028] Working principle: When in use, the base 100 can be moved to the desired position. Before that, a hole for placing the penetrator 103 can be opened at the desired position, and then the handle 401 is turned to drive the screw 400 to rotate, thereby driving the ground plug 402 to move downward, so that the ground plug 402 enters the soil layer to limit the sliding of the universal wheel 102, and then the position pointed by the middle scale 202 of the counterweight block 200 when the bottom of the first contact plate 203 and the top of the penetrator 103 are contacted is recorded, and then the reduction motor 303 is turned on to drive the worm 304 to rotate, thereby driving the two worm wheels 302 to rotate, thereby driving the two rotating rods 300 along The gears 301 rotate in opposite directions, thereby driving the two incomplete gears 301 to rotate in opposite directions, thereby meshing with the rack 204 and driving the counterweight 200 to move upward, thereby driving the resistance plate 203 away from the top of the penetrator 103. When the incomplete gear 301 is disengaged from the rack 204, the counterweight 200 is affected by gravity and drives the resistance plate 203 to hit the top of the penetrator 103, so that it is forced to move downward and insert into the soil layer. At this time, the reduction motor 303 is turned off to calculate the position pointed by the scale 202 and compare it with the initial position, so as to obtain the depth of the standard penetration of the penetrator 103. In this way, multiple standard penetrations can be carried out back and forth to detect the strength of the foundation.

[0029] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
