[0027] In order to further understand the features, technical means, specific purposes and functions achieved by the present utility model, the present utility model will be further described in detail below in conjunction with the drawings and specific implementation manners.
[0028] See Figures 1-7 As shown, the present utility model provides an environment-friendly hydropower station geological exploration drilling and sampling device, including an equipment support 1, a driving frame 2 slidably installed on the equipment support 1, and a drilling and sampling rod 3 rotatably installed on the driving frame 2; the drilling and sampling device further includes a dust-proof cover 4 axially sleeved outside the drilling and sampling rod 3 to prevent drilling dust, a water tank 5 fixed on the equipment support 1 and connected to the dust-proof cover 4 in a through manner to collect drilling dust, and a stirring rod 51 rotatably installed in the water tank 5 to accelerate the flow of water for dust absorption. The outer diameter of the lower part of the rod of the drilling and sampling rod 3 is larger than the outer diameter of the upper part of the rod, and a convex platform-like structure is formed at the position where the rod diameter of the drilling and sampling rod 3 changes. The inner top surface of the dust-proof cover 4 is supported by the convex surface of the convex platform, so that when the drilling and sampling rod 3 moves up to a certain position, the dust-proof cover 4 is driven to move up synchronously, keeping the lower part of the drilling and sampling rod 3 open, so as to dissipate heat of the drilling and sampling rod 3 and extract geological samples.
[0029] When controlling the drilling and sampling rod 3 to penetrate underground for operation, the dust-proof cover 4 covers the outside of the drilling and sampling rod 3 to prevent the dust and fog generated by drilling from spreading outwards. And the dust and fog are transmitted to the water tank 5 through the hose 41 above the dust-proof cover 4, and the dust and fog are quickly absorbed by the liquid in the water tank 5, quickly and effectively realizing the treatment of the dust and fog generated during drilling, and increasing the environmental protection of the use of the drilling and sampling device.
[0030] The equipment support 1 is erected on the ground. The driving control drive frame 2 is sleeved on the equipment support 1 and moves downward. The driving frame 2 controls the downward movement and rotation of the drilling and sampling rod 3. The drilling and sampling rod 3 contacts the ground and gradually penetrates into the ground to complete the drilling and sampling operation. During the downward movement of the drilling and sampling rod 3, the dust-proof cover 4 moves downward synchronously under the action of gravity. The dust-proof cover 4 supports on the ground, forming a sealed space outside the formation drilled by the drilling and sampling rod 3, avoiding the outward diffusion of the dust and fog generated during drilling and affecting the operation of the staff. The dust-proof cover 4 transmits the internal dust and fog to the water tank 5, and the dust and fog are quickly absorbed by the liquid in the water tank 5.
[0031] A twist rod 52 is fixedly connected to the stirring rod 51. A rotating frame 53 is rotatably sleeved on the twist rod 52. The rotating frame 53 is fixedly installed on the driving frame 2. The transmission principle between the twist rod 52 and the rotating frame 53 is similar to the principle of an automatic cleaning rotating mop.
[0032] During the downward movement of the driving frame 2, it drives the synchronously downward movement of the rotating frame 53 fixed on the front side. The rotating frame 53 is sleeved outside the twist rod 52. During its downward movement, the twist rod 52 is rotated. The twist rod 52 drives the stirring rod 51 installed below in the water tank 5 to rotate. Through the linkage structure, the rotation of the stirring rod 51 is controlled to accelerate the flow of the liquid in the water tank 5, thereby accelerating the absorption of the transmitted dust and fog by the liquid in the water tank 5.
[0033] The dust-proof cover 4 and the water tank 5 are connected to each other through a hose 41.
[0034] The dust-proof cover 4 quickly transmits the dust and fog into the interior of the water tank 5 through the hose 41, completing the treatment of the covered dust and fog and avoiding the outward diffusion of the dust and fog after the dust-proof cover 4 is opened.
[0035] A movable sliding frame 42 is fixedly installed on the dust-proof cover 4. The movable sliding frame 42 is slidably installed on the equipment support 1.
[0036] During the downward movement of the dust-proof cover 4, the movable sliding frame 42 fixed to its outside is engaged with the equipment support 1 and slides downward. It maintains the straight downward movement state of the dust-proof cover 4, and also maintains the stability of the movement of the dust-proof cover 4 and its guiding effect on the drilling and sampling rod 3.
[0037] A clamping groove 43 is formed in the movable sliding frame 42. A clamping block 44 is slidably installed at the limiting height of the equipment support 1. A return spring 45 is connected between the clamping block 44 and the equipment support 1. The return spring 45 pushes the clamping block 44 to move horizontally. The shapes of the clamping block 44 and the clamping groove 43 match. The upper and lower surfaces of the clamping block 44 are both inclined surfaces. When the movable sliding frame 42 moves, it pushes the clamping block 44 to move horizontally through the extrusion of the upper and lower inclined surfaces of the clamping block 44.
[0038] When the movable carriage 42 moves downward, the operator can push the movable carriage 42 downward, so that the movable carriage 42 presses the upper inclined surface of the clamping block 44, causing the clamping block 44 to be compressed and inserted into the equipment support 1. When the movable carriage 42 moves downward so that the card slot 43 opened inside corresponds to the position of the clamping block 44, at this time, the clamping block 44 is snapped into the card slot 43 under the elastic thrust of the return spring 45, realizing the limiting effect on the downward position of the movable carriage 42, and reducing the impact of some geological materials splashing outward onto the dust cover 4 during the drilling process on its corresponding position.
[0039] A shock absorption assembly 31 for stabilizing the rotation of the drilling sampling rod 3 is installed in the dust cover 4.
[0040] The shock absorption assembly 31 can maintain the stability of the drilling sampling rod 3 during application.
[0041] The shock absorption assembly 31 includes a cage 311 rotatably installed in the dust cover 4. A roller 312 is rotatably installed on the cage 311. A shock absorption spring 313 is connected between the cage 311 and the inner wall of the dust cover 4. Under the action of the shock absorption spring 313, the roller 312 is pressed against the outer side wall of the drilling sampling rod 3. The drilling sampling rod 3 movably penetrates through the dust cover 4, and the vertical movement of the drilling sampling rod 3 is guided by the dust cover 4.
[0042] When the drilling sampling rod 3 is performing a downward drilling operation, the geological layer generates a certain impact force on the drilling sampling rod 3. The guiding function of the dust cover 4 can relatively maintain the stability of the drilling sampling rod 3 in the vertical direction. At the same time, multiple groups of shock absorption assemblies 31 are arranged on the inner circumference of the dust cover 4. The cage 311 in the shock absorption assembly 31 pushes the roller 312 to press against the outer side wall of the drilling sampling rod 3, and the cage 311 buffers the shaking force and impact force on the drilling sampling rod 3 through the shock absorption spring 313 on the side, keeping the drilling sampling rod 3 stable to complete the drilling work.

[0044] 1. In the present utility model, a dust-proof structure for the drilling sampling rod is provided. When controlling the drilling sampling rod to penetrate underground for operation, the dust cover is sleeved outside the drilling sampling rod to prevent the dust and mist generated by drilling from spreading outward. And the dust cover transfers the dust and mist to the water tank through the hose above, and the dust and mist are quickly absorbed by the liquid in the water tank, quickly and effectively realizing the treatment of the dust and mist generated during drilling, and increasing the environmental protection of the use of this drilling sampling device.
[0045] 2. The present utility model is provided with a structure for accelerating the fusion of dust and mist with the liquid in the water tank. During the process of the driving frame controlling the downward movement of the drilling and sampling rod, the driving frame synchronously drives the rotating frame to move. The rotating frame is sleeved outside the twist drill rod and moves downward to control the rotation of the twist drill rod and the stirring rod. The stirring rod accelerates the flow of the liquid in the water tank, thereby improving the absorption of the transmitted dust and mist by the liquid in the water tank.
[0046] 3. The present utility model is provided with a shock-absorbing structure for the drilling and sampling rod. When the drilling and sampling rod moves downward for drilling, the cage and the rollers arranged inside the dust-proof cover are elastically pressed against the outside of the drilling and sampling rod being drilled. Under the action of the dust-proof cover and the shock-absorbing structure inside it, the drilling and sampling rod can be kept moving vertically deep into the ground, buffering and reducing the shaking force and impact force generated during the drilling process, so as to keep the drilling and sampling rod relatively stable to complete the sampling operation.
