DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] like Figure 1 As shown, the utility model provides a working platform for water conservancy engineering survey and sampling, including a stabilizing plate 1 and a platform 3, the upper surface of the stabilizing plate 1 is fixedly connected with four supporting columns 2 in a rectangular array, the upper ends of the four supporting columns 2 are fixedly connected to the lower surface of the platform 3, the upper surface of the stabilizing plate 1 is provided with a protective component 9, the upper surface of the platform 3 is fixedly connected with a U-shaped frame 4, the left and right sides of the U-shaped frame 4 are fixedly connected with two motors 1 5 in the horizontal direction, the output shafts of the two motors 1 5 are fixedly connected with two threaded rods 6, the outer surfaces of the two threaded rods 6 are threadedly connected with a lifting plate, the middle part of the upper surface of the lifting plate is fixedly connected with a motor 2 7, the output shaft of the motor 2 7 penetrates and moves inside the lifting plate and is fixedly connected with a fixed column 10, the outer surface of the fixed column 10 penetrates and moves inside the platform 3, and the lower end of the fixed column 10 is fixedly connected with a sampling tube 8;

[0028] The motor 1 5 and the motor 2 7 are electrically connected to the external power supply through electric wires to start, so that after the motor 1 5 is started, it drives the threaded rod 6 to rotate, so that the lifting plate moves downward, and at the same time, the motor 2 7 drives the fixed column 10 to rotate, so that the sampling tube 8 moves downward and contacts the ground, so that the sampling tube 8 performs sampling. The protection component 9 is provided to facilitate the protection during sampling to prevent soil splashing. After sampling, the motor 2 7 stops working, and the motor 1 5 rotates in the opposite direction to drive the threaded rod 6 to move the lifting plate upward, thereby driving the fixed column 10 and the sampling tube 8 upward, so that the sampling tube 8 is separated from the ground, and then the protection component 9 is opened, so that the sampled soil is taken out through the setting of the internal structure of the sampling tube 8.

[0029] like Figure 2 As shown, a buffer pad 81 is fixedly connected to the upper surface of the inner wall of the sampling tube 8, and an extrusion plate 82 is overlapped on the lower surface of the buffer pad 81. A slide bar 83 is fixedly connected to the middle part of the lower surface of the buffer pad 81. The outer surface of the slide bar 83 penetrates and slides inside the extrusion plate 82. The lower end of the slide bar 83 is fixedly connected to a spring block 85. The outer surface of the slide bar 83 is sleeved with a spring 84. Two vertical grooves 86 communicating with each other are provided on the left and right sides of the outer surface of the buffer pad 81. Two blocks are slidably connected inside the two vertical grooves 86. The opposite surfaces of the two blocks are fixedly connected to the outer surface of the extrusion plate 82. Two L-shaped plates 87 are fixedly connected to the surface mirror images of the two blocks. Circular blocks 88 are fixedly connected to the horizontal opposite surfaces of the two L-shaped plates 87. The middle part of the circular block 88 penetrates and slides with the outer surface of the fixed column 10. Two limiting grooves are provided at the lower front and rear sides of the fixed column 10. Two limiting components 89 are provided in the internal mirror images of the limiting grooves.

[0030] When it is necessary to take out the soil in the sampling tube 8, the circular block 88 is loosened by the setting of the limiting component 89. Due to the action of the stretched spring 84, the squeezing plate 82 is pulled downward to slide downward on the outer surface of the sliding rod 83. Due to the action of the squeezing plate 82 after sliding, the soil is pushed out of the interior of the sampling tube 8. When it is necessary to pull the L-shaped plate 87 upward to drive the circular block 88 to slide on the surface of the fixed column 10 before sampling, the setting of the square block in the vertical groove 86 drives the squeezing plate 82 to move upward, thereby driving the spring 84, so that the spring 84 is in a pulled state. When the circular block 88 moves upward to the appropriate position, the position of the circular block 88 is limited by the setting of the limiting component 89, thereby facilitating the sampling of the sampling tube 8. Through the setting of the buffer pad 81, when sampling, the soil enters the sampling tube 8 and contacts the squeezing plate 82, so that the buffer pad 81 has a buffering effect.

[0031] like Figure 3As shown, the two limiting components 89 include two blocking blocks 891, and the opposite surfaces of the two blocking blocks 891 are fixedly connected with two elastic rubber blocks 892, and the outer surfaces of the two elastic rubber blocks 892 are fixedly connected with the inside of the two limiting grooves. The outer surfaces of the two blocking blocks 891 are provided with left-right communicating card slots, and the lower parts of the outer surfaces of the two blocking blocks 891 are provided with inclined surfaces, and the inside of the card slots is card-engaged with the inner side of the circular block 88;

[0032] When the circular block 88 needs to be loosened by the limiting component 89, the elastic rubber block 892 is contracted and deformed by pressing the blocking block 891, so that the slot in the blocking block 891 is separated from the inner side of the circular block 88, thereby achieving the loosening of the circular block 88. When the circular block 88 needs to be positionally restricted, the circular block 88 is moved upward to an appropriate position and the inclined surface in the blocking block 891 is squeezed, so that the elastic rubber block 892 is deformed and contracted, so that the inner side of the circular block 88 enters the slot, thereby limiting the position.

[0033] like Figure 4 - Figure 6 As shown, two transverse grooves 11 are provided on the left and right sides of the upper surface of the stabilizing plate 1, and the protective component 9 includes two frame plates 91. Two moving blocks are fixedly connected to the middle of the lower surfaces of the two frame plates 91, and the outer surfaces of the two moving blocks are slidably connected to the inside of the two transverse grooves 11. Two limiting components 92 are mirror-imaged on the front and rear sides of the two frame plates 91. A square opening 12 communicating with each other from top to bottom is provided in the middle of the lower surface of the stabilizing plate 1. Two plug posts 13 are fixedly connected to the left and right sides of the lower surface of the stabilizing plate 1. The two limiting components 92 include two plates 921. Two limiting posts 922 are slidably connected to the middle of the left sides of the two plates 921. The outer surfaces of the two limiting posts 922 are fixedly connected to the surface of the left frame plate 91. The ends of the two limiting posts 922 away from the plates 921 are fixedly connected to the baffles 923. Grooves are provided on the right sides of the upper and lower surfaces of the plates 921. Rubber blocks 924 are fixedly connected to the inside of the grooves. The outer surfaces of the rubber blocks 924 are fixedly connected to the surface of the right frame plate 91.

[0034] By moving the left and right frame plates 91, the moving block is inside the transverse groove 11 so that the two frame plates are close to the middle and contact each other, and then the plate 921 is moved to make the plate 921 slide on the outer surface of the limiting column 922. When sliding to the appropriate position, the groove in the plate 921 contacts the surface of the rubber block 924, thereby limiting the position. The elastic action of the rubber block 924 makes the outer surface of the rubber block 924 fit tightly with the inner wall of the groove, thereby realizing the position limitation of the two frame plates 91. The square opening 12 is provided to facilitate the use of the sampling tube 8. The plug post 13 is provided to facilitate the insertion into the ground. The stabilizing plate 1 is provided to facilitate the improvement of stability when in contact with soft ground. When on soft ground, the force-bearing area of ​​the stabilizing plate 1 is increased, so that the stability is good and the working platform will not be tilted.

[0035] The following is a detailed description of the working principle of the water conservancy engineering survey and sampling work platform.

[0036] By moving the left and right frame plates 91, the moving block is inside the transverse groove 11 so that the two frame plates are close to and contact with each other, and then the moving plate 921 and the limiting column 922 cooperate. When the plate 921 moves to the appropriate position, the groove contacts the surface of the rubber block 924, thereby limiting the position, thereby preventing the soil from splashing during sampling. Then, after the motor 1 5 is started, the threaded rod 6 is driven to rotate, so that the lifting plate moves downward. At the same time, the motor 2 7 drives the fixed column 10 to rotate, thereby driving the sampling tube 8 to move downward and contact with the ground so that the sampling tube 8 can perform sampling. When the sampling is completed, the elastic rubber block 892 is contracted and deformed by pressing the blocking block 891, so that the slot in the blocking block 891 is separated from the inner side of the circular block 88, thereby realizing the loosening of the circular block 88. After loosening, the squeezing plate 82 is pulled downward under the action of the spring 84, so that the squeezing plate 82 pushes the soil out of the inside of the sampling tube 8, which is convenient for taking out the sampled soil.

[0037] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
