[0029] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] Reference Figure 1-Figure 3 : A water conservancy project foundation detection device, the device includes: a frame 1, a probe rod assembly 2, a hammer head 3, a lifting rod 4, a clamping mechanism 5 and a driving mechanism 6, the frame 1 is vertically provided with a probe rod assembly 2 at the bottom, the hammer head 3 is vertically and liftably arranged above the probe rod assembly 2, the lifting rod 4 is vertically and liftably arranged above the hammer head 3, and a clamping mechanism 5 is arranged at its lower end, and the driving mechanism 6 is used to drive the lifting rod 4 to rise and fall; wherein, the clamping mechanism 5 includes: a clamping claw 501 and an elastic member 502, the upper surface of the hammer head 3 is provided with a clamping head 3 01, the lower end of the lifting rod 4 is rotatably provided with clamping jaws 501 on both sides thereof, the elastic member 502 is horizontally arranged between each clamping jaw 501, and its two ends are respectively arranged on the side of each clamping jaw 501 close to each other, the frame body 1 is coaxially provided with a conical groove 101 on the circumference of the rod body of the lifting rod 4, the lower end of the clamping jaw 501 is provided with a clamping head 50101 matched with the clamping head 301, and the upper end is provided with a loosening driving rod 50102 matched with the conical groove 101, and the lower surface of the clamping head 50101 is set as an arc surface matched with the clamping head 301.

[0031] The present application starts the driving mechanism 6 to drive the lifting rod 4 to descend. When the arc surface of the chuck 50101 at the lower end of the clamping jaw 501 contacts the clamping head 301, the clamping jaw 501 will rotate around its rotating connection and cooperate with the elastic member 502 to achieve reset, thereby achieving clamping with the clamping head 301. Then the driving mechanism 6 will drive the lifting rod 4 to rise, so as to drive the hammer head 3 to rise. When the upper end of the clamping jaw 501 is released, the driving rod 50102 will cooperate with the conical groove 101, thereby driving the clamping jaw 501 to rotate around its rotating connection. The chuck 50101 is separated from the clamping head 301, and the hammer head 3 falls, thereby hammering the probe rod assembly 2 to hammer it into the ground. Finally, the accurate bearing capacity of the foundation is calculated based on the depth of the probe rod assembly 2 entering the ground and the weight of the hammer head 3. Since the hammer head 3 only contains its own weight when it falls, it is convenient for the user to measure its accurate weight and thus obtain accurate results.

[0032] Reference Figure 3 : The elastic member 502 is provided with a clamping ball head 50201 at two opposite ends thereof, and each clamping jaw 501 is provided with a clamping ball groove 50103 matched with the clamping ball head 50201 on one side close to the elastic member 502.

[0033] The elastic member 502 of the present application is respectively clamped in the clamping ball groove 50103 through the clamping ball heads 50201 at both ends, thereby preventing the clamping claw 501 from repeatedly stretching and twisting the elastic member 502 during the rotation process, thereby reducing its service life.

[0034] Reference Figure 2 : A plurality of guide rods 102 are arranged on the frame body 1 around and vertically penetrate the hammer head 3 and the lifting rod 4.

[0035] The hammer head 3 and the lifting rod 4 of the present application are designed to be able to be lifted and lowered stably, thereby ensuring that the clamping assembly can clamp and release the hammer head 3 each time, and make the hammer head 3 hammer the probe rod assembly 2, so that the hammering force applied to the probe rod assembly 2 is the same each time.

[0036] Reference Figure 4 The driving mechanism 6 includes: a gear 601 and a driving assembly 602. The lifting rod 4 is provided with a plurality of ring teeth 401 along its axial direction. The frame is rotatably provided with a gear 601 meshing with the ring teeth 401. The driving assembly 602 is provided on the frame to drive the gear 601 to rotate.

[0037] In the present application, the driving assembly 602 is started to drive the gear 601 to rotate, so that the lifting rod 4 is driven to move up and down through the cooperation between the gear 601 and the ring gear 401 .

[0038] Reference Figure 4 and Figure 5 The driving assembly 602 includes: a driving motor 60201, a worm wheel 60202 and a worm 60203. The worm wheel 60202 is coaxially arranged on one side of the gear 601. The driving motor 60201 is arranged on a frame, and its output shaft is coaxially arranged with a worm 60203 meshing with the worm wheel 60202.

[0039] In the present application, the driving motor 60201 is started to drive the worm 60203 to rotate, so that the gear 601 is driven to rotate through the cooperation between the worm 60203 and the worm wheel 60202, thereby achieving stable lifting of the lifting rod 4.

[0040] Reference Figure 3 A counterweight groove 302 is recessed on the upper surface of the hammer head 3, and a plurality of counterweight blocks 303 are stacked and placed in the counterweight groove 302. A screw rod 304 is vertically arranged inside each counterweight block 303, and a nut 305 is threadedly assembled on the screw rod 304.

[0041] Through this design, the present application can adjust the hammering force of the hammer head 3 by adjusting the number of breeding blocks inserted.

[0042] Reference Figure 2 , Figure 5 and Figure 6 The probe rod assembly 2 includes: a telescopic sleeve 201, a rotating block 202 and a threaded probe rod 203. The telescopic sleeve 201 is vertically arranged at the bottom of the frame 1, and the rotating block 202 is coaxially and rotatably arranged at its open end. The threaded probe rod 203 is coaxially threadedly assembled in the rotating block 202. The threaded portion of the threaded probe rod 203 is provided with a limiting groove 20301 along its axial direction. A limiting block 20101 adapted to the limiting groove 20301 is arranged in the telescopic sleeve 201.

[0043] The present application places the frame 1 vertically on the ground, and then twists the rotating block 202 to partially screw the threaded probe rod 203 into the foundation, so that the frame 1 stands on the ground, and the threaded probe rod 203 can also be screwed out and then inserted into the foundation.

[0044] Reference Figure 6 : A plurality of anti-slip grooves 20201 are arranged around the circumference of the rotating block 202.

[0045] The present application adopts such a design to facilitate the user to twist the rotating block 202 and prevent slipping.

[0046] Reference Figure 6 : The lower end of the threaded probe rod 203 is tapered.

[0047] The present application adopts such a design to facilitate the user to insert the threaded probe rod 203 into the foundation.

[0048] When the device provided by the present invention is in use, the driving mechanism 6 is started to drive the lifting rod 4 to descend. When the arc surface of the chuck 50101 at the lower end of the clamping jaw 501 contacts the clamping head 301, the clamping jaw 501 will rotate around its rotating connection and cooperate with the elastic member 502 to achieve reset, thereby achieving clamping with the clamping head 301, and then the driving mechanism 6 will drive the lifting rod 4 to rise, so as to drive the hammer head 3 to rise. When the upper end of the clamping jaw 501 is released, the driving rod 50102 will cooperate with the conical groove 101, thereby driving the clamping jaw 501 to rotate around its rotating connection, the chuck 50101 is separated from the clamping head 301, and the hammer head 3 falls, thereby hammering the probe rod assembly 2 to hammer it into the ground. Finally, according to the depth of the probe rod assembly 2 entering the ground and the weight of the hammer head 3, the accurate bearing capacity of the foundation is calculated; since the hammer head 3 only contains its own weight when falling, it is convenient for the user to measure its accurate weight and thus obtain an accurate result.
