[0031] Reference Figure 1 and Figure 2 as well as Figure 3 As shown, the utility model provides a technical solution: a high-precision geophysical shear wave testing device for engineering survey stratum division, comprising a testing device body 1, a cover body 2 is rotatably connected to the surface of the testing device body 1, a display screen 3 is electrically connected to the upper surface of the testing device body 1, a plug 4 is electrically connected to the surface of the plug 4, a detection line 5 is electrically connected to the surface of the testing device body 1, an anti-falling device 6 is provided on the surface of the testing device body 1, and a supporting device 7 is provided on the lower surface of the testing device body 1.
[0032] The specific arrangement and function of the anti-falling device 6 and the supporting device 7 will be described in detail below.
[0033] Reference Figure 4 and Figure 5As shown, in the present embodiment: the anti-falling device 6 comprises a rectangular groove 61, which is provided on the surface of the test equipment body 1, and a slider 62 is slidably connected to the inner wall of the rectangular groove 61, and the surface of the slider 62 is rotatably connected to a limiting plate 63, and a screw 65 is threadedly connected to the surface of the limiting plate 63, and a handle 64 is fixedly connected to one end of the screw 65, and a threaded hole 67 is provided on the surface of the test equipment body 1, and the screw 65 is threadedly connected to the threaded hole 67. By setting the anti-falling device 6, the position of the detection line 5 can be effectively fixed to ensure that the detection line 5 is firmly connected to the plug 4 of the test equipment body 1, and the detection line 5 is prevented from being separated from the plug 4 due to external pulling, and the detection line 5 is kept in stable contact with the test equipment, so as to ensure that the test equipment body 1 can perform the detection work normally, thereby improving the stability of the geophysical shear wave test equipment, and an anti-skid pad 69 is glued on the surface of the limiting plate 63, and the anti-skid pad 69 is slidably connected to the detection line 5. The anti-skid pad 69 is made of rubber, and the inspection line is moved along the surface of the anti-skid pad 69. The anti-slip pad 69 increases the friction between the detection line 5 and the limit plate 63, and improves the stability of the limit plate 63 clamping the detection line 5. The surface of the test equipment body 1 is fixedly connected with a stopper 68, which can support the limit plate 63, facilitate the screw 65 to align with the threaded hole 67, and then facilitate the fixation of the limit plate 63. The other end of the screw 65 is glued with a flexible pad 66, and the surface of the limit plate 63 is provided with an inclined surface, which plays a guiding role to avoid the situation where the adaptation between the detection line 5 and the limit plate 63 is high and it is inconvenient to clamp the detection line 5. When the detection line 5 is stuck and fixed, the handle 64 is turned again, and the handle 64 will drive the screw 65 to move with the help of the thread in the limit plate 63. The movement of the screw 65 will drive the flexible pad 66 to move until the flexible pad 66 is against the surface of the test equipment body 1. The flexible pad 66 can protect the test equipment body 1 to avoid the situation where the screw 65 contacts the test equipment body 1 and causes wear of the test equipment body 1.
[0034] Reference Figure 6 and Figure 7As shown, specifically, the support device 7 includes four fixing rods 71, and the four fixing rods 71 are fixedly connected to the test device body 1. One end of the four fixing rods 71 is fixedly connected to the bottom plate 72. By setting the support device 7, the test device body 1 can be effectively supported to avoid the wear problem caused by direct contact with the ground. Continuous wear will accelerate the aging of the equipment and shorten its service life. Through appropriate support, the wear of the equipment can be reduced, its service life can be extended, and the accuracy of the test results can be ensured. The surface of the test device body 1 is fixedly connected with two fixing blocks 73, two The surfaces of the fixed blocks 73 are both threadedly connected with screw rods 74, and one end of the two screw rods 74 is fixedly connected with a pointed cone 75. When the pointed cone 75 contacts the ground, the screw rod 74 continues to be rotated to insert the pointed cone 75 into the ground. The pointed cone 75 can fix the position of the test device body 1, thereby improving the stability of the test device body 1 placed on the ground. The surfaces of the two fixed blocks 73 are both fixedly connected with a circular ring 76, and the pointed cone 75 is located in the circular ring 76. The circular ring 76 can prevent the pointed cone 75 from being exposed to the outside and causing harm to personnel, thereby reducing the risk of injury to personnel.
[0035] Working principle: in the process of engineering survey and stratum division, when it is necessary to use the test equipment body 1 to detect the geophysical shear wave of the soil, first insert one end of the detection line 5 into the plug 4, and then turn the handle 64. The rotation of the handle 64 will cause the screw 65 to rotate. The screw 65 moves with the help of the threaded hole 67 and the thread in the limit plate 63, so that the screw 65 is out of contact with the threaded hole 67. Then, the limit plate 63 is pulled, and the limit plate 63 drives the slider 62 to slide along the inner wall of the rectangular groove 61, and the slider 62 moves in the direction close to the detection line 5. By rotating the limit plate 63, the limit plate 63 will be out of contact with the stopper 68. When the limit plate 63 is not used to fix the detection line 5, the stopper 68 can support the limit plate 63, so that the screw 65 is conveniently aligned with the threaded hole 67, thereby facilitating the fixation of the limit plate 63. Then, the limit plate 63 is pushed in the direction close to the detection line 5. When the detection line 5 contacts the inclined surface of the limit plate 63, the limit plate 63 is pushed, and the inspection line slides along the surface of the anti-skid pad 69. The anti-skid pad 69 increases the distance between the detection line 5 and the limit plate 6 3, improves the stability of the limit plate 63 clamping the detection line 5, and the inclined surface plays a guiding role to avoid the situation where the fit between the detection line 5 and the limit plate 63 is high and it is inconvenient to clamp the detection line 5. When the detection line 5 is clamped and fixed, turn the handle 64 again, the handle 64 will drive the screw 65 to move with the help of the thread in the limit plate 63, and the movement of the screw 65 will drive the flexible pad 66 to move until the flexible pad 66 is against the surface of the test equipment body 1. The flexible pad 66 can protect the test equipment body 1 to avoid the screw 65 contacting the test equipment body 1 and causing wear of the test equipment body 1. By setting the anti-falling device 6, the position of the detection line 5 can be effectively fixed to ensure that the detection line 5 is firmly connected to the plug 4 of the test equipment body 1, and avoid the detection line 5 being pulled by the outside and separated from the plug 4, so as to maintain the stable contact between the detection line 5 and the test equipment, and ensure that the test equipment body 1 can perform the detection work normally, thereby improving the stability of the geophysical shear wave test equipment.
[0036] When the test device body 1 is placed on the ground for testing, the bottom plate 72 will contact the ground, so that the test device body 1 can be supported, and then the screw rod 74 is rotated, and the screw rod 74 moves with the help of the thread in the fixing block 73. The movement of the screw rod 74 will drive the pointed cone 75 to move closer to the ground. When the pointed cone 75 contacts the ground, the screw rod 74 is continued to be rotated to insert the pointed cone 75 into the ground. The pointed cone 75 can fix the position of the test device body 1, thereby improving the stability of the test device body 1 placed on the ground. The use of the test device body 1 is completed. After that, it is necessary to rotate the screw rod 74 again to make the pointed cone 75 break contact with the ground, and then continue to rotate the screw rod 74 to make the pointed cone 75 located in the ring 76. The ring 76 can prevent the pointed cone 75 from being exposed to the outside and causing harm to personnel, thereby reducing the risk of injury to personnel. By setting up the supporting device 7, the test equipment body 1 can be effectively supported to avoid wear problems caused by direct contact with the ground. Continuous wear will accelerate the aging of the equipment and shorten its service life. Through appropriate support, the wear on the equipment can be reduced, its service life can be extended, and the accuracy of the test results can be ensured.
