Technical Field

[0001] The utility model relates to the technical field of dam detection, in particular to a dam strength detection device. Background Art

[0002] The strength test of a dam is the strength test of the dam soil. Soil strength refers to the compactness of the arrangement of soil particles, also known as soil hardness and soil firmness. Soil penetration resistance, that is, the resistance of soil to wedging, is generally expressed by the resistance of a metal plunger or probe when pressed into the soil (in Pa). The resistance of the soil to the plunger is composed of soil shear resistance, compression force and friction force, etc., and is a synthetic indicator of soil strength.

[0003] A dam soil strength detection device disclosed in publication number CN208505808U, although, through the action of a fixing device, the guide assembly and the detector body are effectively connected, and then by adjusting the action of the hydraulic rod, the guide plate is driven to move, so that the guide slot is engaged with the outside of the shock-absorbing sleeve rod, thereby effectively guiding the moving detection probe, while improving the verticality of the detection probe during operation, further improving the accuracy of the detection data.

[0004] However, this dam soil strength detection device has the following disadvantages:

[0005] (1) When testing the soil strength of a dam, other soil monitoring needs to be done by sampling and testing. Personnel can only perform strength testing on it, which is not widely used;

[0006] (2) When testing the soil penetration resistance, that is, the soil's resistance to wedging, it is necessary to press, and the pressing operation needs to be done manually, which is rather troublesome. Utility Model Content

[0007] The technical problem solved by the utility model is to provide a dam strength detection device which is highly practical, can be simply operated and has a relatively simple structure. It solves the problems raised in the above-mentioned background technology that other soil monitoring requires sampling and detection, personnel can only perform strength detection on it, and its application is not wide enough. When detecting the soil penetration resistance, that is, the soil's resistance to wedging, it needs to be pressed, and manual operation is required when pressing.

[0008] To achieve the above purpose, the utility model is implemented through the following technical solutions: a dam strength detection device, including a detection platform, a mounting groove is opened on the surface of the detection platform, a servo motor is fixedly installed inside the mounting groove, and two meshing gears are arranged at the output end of the servo motor.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figures 1 to 4 The utility model provides a technical solution: a dam strength detection device, including a detection platform 1, baffles are provided on both sides of the surface of the detection platform 1, the baffles and the detection platform 1 are welded, a horizontally arranged installation groove is opened on the surface of the detection platform 1, and a servo motor 2 is fixedly installed inside the installation groove;

[0025] The baffle is provided to facilitate the installation and positioning of the testing platform 1 by personnel, thereby improving the efficiency of the installation of the testing platform 1 by personnel.

[0026] The output end of the servo motor 2 is provided with two meshing gears 3, and the axis of the output end of the servo motor is extended in the left-right direction. Among the two gears, the axis of one gear is horizontally arranged, and the axis of the other gear is vertically arranged. The gear with the horizontal axis is coaxially fixed to the output section of the servo motor, that is, the output shaft. The gear 3 with the vertical axis is provided with a thread groove inside, and the internal thread of the thread groove is penetrated by a threaded rod 4. The threaded rod cooperates with the anti-rotation guide of the detection platform 1, that is, the threaded rod cannot rotate relative to the detection platform 1, but the threaded rod can move up and down. The threaded rod and the gear matched with it constitute a screw nut mechanism. When the servo motor is working, the gear with the vertical axis rotates without moving axially, and the threaded rod does not rotate but can move up and down.

[0027] A pressing plate 5 is fixedly installed at one end of the threaded rod 4, a closed ring 6 is fixedly installed at the bottom of the pressing plate 5, a sampling assembly 7 is fixedly installed inside the closed ring 6, a sealing plate 8 is fixedly installed on the surface of the installation groove, an embedding groove is opened on one side of the surface of the sealing plate 8, a fan for heat dissipation is embedded inside the embedding groove, and limiting grooves are opened at the four corners of the surface of the sealing plate 8, and the internal threads of the limiting grooves are penetrated by limiting bolts for positioning;

[0028] The sampling assembly 7 includes a hinge 701 fixedly installed on the opposite sides of the closed ring 6, and an arc plate 702 is fixedly installed at the bottom of the hinge 701. The two arc plates 702 form a full circle, that is, each arc plate 702 is a semicircular result. A limit ring 703 is fixedly installed inside the closed ring 6, and limit plates 704 are fixedly installed on the opposite sides of the inside of the limit ring 703. The limit ring 703 and the limit plate 704 are located on the lower side of the arc plate. The two limit plates are arranged at intervals on the left and right, and each limit plate is located on the lower side of the corresponding arc plate. The left and right sides and the circumferential direction of the two limit plates constitute a soil passing space.

[0029] During use, the closed ring 6 will move with the downward movement of the pressing plate 5. When it moves to the surface of the soil, the soil will push the arc plate 702, and the arc plate 702 will rotate accordingly. When the soil rotates, it enters the interior of the closed ring 6. After entering the interior, the servo motor rotates in the opposite direction, and the threaded rod moves upward. When the closed ring is lifted up with the pressing plate and the threaded rod, the arc plate has a downward swinging tendency. The arc plate 702 will be limited by the limiting plate 704 on the limiting ring 703 to block the soil, so as to carry out sampling, which plays a role in facilitating personnel to take samples;

[0030] The sealing plate 8 is provided to reduce the possibility of rain falling on the servo motor 2 and causing the servo motor 2 to malfunction. At the same time, the fan can remove the heat energy generated inside the installation slot.

During use, the closed ring 6 will move with the downward movement of the pressing plate 5. When moving to the surface of the soil, the soil will push the arc plate 702, and the arc plate 702 will rotate accordingly. When the soil rotates, it enters the interior of the closed ring 6. After entering the interior, the arc plate 702 will be limited by the limit plate 704 on the limit ring 703 to block the soil, so as to carry out sampling, which makes it convenient for personnel to take samples.

[0034] In the utility model, the working steps of the device are as follows:

[0035] The first step: connect the servo motor 2 to the power supply, and its output end will drive the gear 3 to rotate. When the gear 3 rotates, the threaded rod 4 does not rotate, and the threaded rod 4 will move downward accordingly, and when moving, it will drive the pressing plate 5 to move downward;

[0036] The second step: the closed ring 6 will move along with the downward movement of the pressing plate 5. When it moves to the surface of the soil, the soil will push the arc plate 702, and the arc plate 702 will rotate accordingly. The rotating soil enters the interior of the closed ring 6. After entering the interior, the arc plate 702 will be limited by the limiting plate 704 on the limiting ring 703 to block the soil for sampling.
