[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-Figure 8 The present invention provides a water level observation device for hydrogeological exploration, comprising: A water tank 1, an upper box body 6 is fixedly installed on the top of the water tank 1, a partition plate 8 is fixedly installed in the inner cavity of the water tank 1, a suspension rope 2 is fixedly installed on the top of the water tank 1, and a transparent plate 3 is provided on one side of the upper box body 6; a drain valve is provided on the top of the water tank 1.

[0019] A water pressure detection assembly 4 is arranged inside the upper box body 6. The water pressure detection assembly 4 includes a water inlet 401. The water inlet 401 is opened on the front side of the water storage tank 1. A movable sleeve 402 is fixedly installed on the front side of the inner cavity of the water storage tank 1. The inner cavity of the movable sleeve 402 is movably sleeved with a water pressure push plate 413. A first telescopic rod 408 is fixedly installed on the rear side of the water pressure push plate 413. The rear end of the first telescopic rod 408 is connected to the rear side of the inner cavity of the upper box body 6. The outer side of the first telescopic rod 408 is movably sleeved with a first spring 409. The two ends of the first spring 409 are respectively fixed at The rear side of the first telescopic rod 408 and the rear side of the inner cavity of the upper box body 6, the rear side of the hydraulic push plate 413 are connected with a rack 415 by bolts, and an auxiliary plate 410 is fixedly installed on the top of the partition plate 8. One side of the auxiliary plate 410 is rotatably connected with a first gear 411, and the first gear 411 is meshed with the rack 415. A ratchet assembly 412 is fixedly installed on the top of the auxiliary plate 410, one side of the ratchet on the ratchet assembly 412 is connected to the second gear 414, and the other side of the ratchet on the ratchet assembly 412 is connected with a pointer 417, and a dial 416 is fixedly installed on one side of the auxiliary plate 410.

[0020] The water pressure detection component 4 also includes a water baffle 403, a support plate 404, a return spring 405, a rotating stick 406 and a connecting rope 407. The front side of the movable sleeve box 402 is movably sleeved with the water baffle 403, and the support plate 404 is fixedly installed on the top of the water baffle 403. The side surface of the upper part of the support plate 404 is connected to the rotating stick 406 by means of the return spring 405. The outer side of the rotating stick 406 is fixedly connected with the connecting rope 407, and one end of the connecting rope 407 passes through the top of the upper box body 6. A water pressure detection component 4 is provided through the inner cavity of the water tank 1. When the water tank 1 enters the water source for use, the pressure in the water will push the water pressure push plate 413 to move toward the rear side of the water tank 1, driving the first gear 411 to move, thereby driving the first gear 411 and the second gear 414 to rotate. The second gear 414 drives the pointer 417 to rotate by using the ratchet component 412. By observing the position where the pointer 417 stops on the dial 416, it is convenient to obtain the water pressure here. A water inlet component 7 is provided under the partition plate 8. When the sample water is poured into the bottom of the partition plate 8 by using the water full self-stop valve 703, it can be obtained what the water depth is.

[0021] The width of the water baffle 403 is equal to that of the support plate 404, and the front side of the water baffle 403 fits the front side of the inner cavity of the water storage tank 1. By making the width of the water baffle 403 equal to that of the support plate 404, the support plate 404 can move downward with the water baffle 403, so that the support plate 404 can enter the movable sleeve box 402.

[0022] A water inlet assembly 7 is provided below the inner cavity of the water storage tank 1, and the water inlet assembly 7 includes a connecting frame 701, a connecting port 702, a water full stop valve 703, a liquid inlet pipe 704, and a liquid outlet pipe 705. The connecting frame 701 is fixedly installed at the bottom of the water baffle 403, and a connecting port 702 is opened on the connecting frame 701. A water full stop valve 703 is provided on the front side of the water storage tank 1, and a liquid inlet pipe 704 and a liquid outlet pipe 705 are respectively provided on the front and rear sides of the water full stop valve 703. The liquid inlet pipe 704 is fixedly sleeved on the front side of the water storage tank 1, and the rear side of the liquid outlet pipe 705 is in contact with the front side of the connecting frame 701. By moving the water baffle 403 downward, the connecting frame 701 and the connecting port 702 are driven to move downward, and the connecting port 702 is moved to a position in contact with the liquid outlet pipe 705, so that the liquid outlet pipe 705 is connected to the interior of the water tank 1. At this time, water enters the water tank 1 from the liquid inlet pipe 704 and the liquid outlet pipe 705. Due to the function of the water-full automatic stop valve 703 itself, the water-full automatic stop valve 703 can be automatically closed when the water in the water tank 1 is full of water, thereby preventing the upper layer of water from entering the water tank 1 when the water tank 1 is pulled ashore, resulting in mixing with the lower layer of water, affecting the accuracy of subsequent water source detection, and can automatically collect the water source for detecting the water pressure position.

[0023] A second telescopic rod 706 is fixedly installed at the bottom of the connecting frame 701, and the bottom end of the second telescopic rod 706 is fixed to the bottom of the inner cavity of the water tank 1. A second spring 707 is movably sleeved on the outer side of the second telescopic rod 706, and both ends of the second spring 707 are respectively fixed to the bottom of the connecting frame 701 and the bottom of the inner cavity of the water tank 1.

[0024] When the communication port 702 is located above the liquid outlet pipe 705 , the second telescopic rod 706 and the second spring 707 are in a stretched state.

[0025] A guide wheel 5 is fixedly mounted on the top of the water tank 1, and one end of the connecting rope 407 extends outward through the guide wheel 5. The connecting rope 407 is guided by the guide wheel 5.

[0026] The diameter of the first gear 411 is greater than the diameter of the second gear 414, and the first gear 411 is located between the second gear 414 and the rack 415. Since the diameter of the first gear 411 is greater than the diameter of the second gear 414, when the water pressure push plate 413 moves to a smaller position, the second gear 414 can be used to enlarge the moving range of the water pressure push plate 413, so as to observe the rotation angle of the pointer 417 and obtain the water pressure situation.

[0027] Working principle: When the water tank 1 is put into use, the connecting rope 407 is pulled upward to lift the support plate 404 upward, driving the water baffle plate 403 to move upward, and blocking the water inlet 401. At this time, the water baffle plate 403 is pulled upward to drive the connecting frame 701 to move upward, stretching the second telescopic rod 706 and the second spring 707, and the return spring 405 is in a torsion state; The water tank 1 is put into the water, and the lifting rope 2 and the connecting rope 407 are unwound, so that the water tank 1 and the upper box body 6 are sunk into the water, and the connecting rope 407 is ensured to be in a stretched state. When the water tank 1 reaches a certain position, one end of the connecting rope 407 is loosened, and the support plate 404 and the water baffle plate 403 are not restricted by external force. The second telescopic rod 706 and the elastic force of the second spring 707 are used to move downward, and the rotating rod 406 rotates as the return spring 405 is reset, and the connecting rope 407 is wound around the outside of the rotating rod 406, so that the connecting rope 407 is prevented from being scattered in the water source and entangled with other objects, which affects the subsequent pulling of the water tank 1 to the shore. When the support plate 404 and the water baffle plate 403 move downward, the front side of the water inlet 401 is opened, so that the water source enters the movable casing 402 to squeeze the water pressure push plate 413 and drive the rack 415 to move. Since the rack 415 is meshed with the first gear 411, the first gear 411 is driven to rotate. Since the first gear 411 is meshed with the second gear 414, the second gear 414 is driven to rotate. Since the second gear 414 is connected to the pointer 417 by the ratchet assembly 412, the pointer 417 is driven to rotate in one direction, thereby avoiding the pointer 417 from rotating due to unstable water pressure in the water, which affects the accuracy of the water level observation data. At this time, as the water retaining plate 403 moves downward, the connecting frame 701 and the connecting port 702 are driven to move downward, and the connecting port 702 is moved to a position in contact with the liquid outlet pipe 705, so that the liquid outlet pipe 705 is connected with the inside of the water storage tank 1. At this time, the water source enters the water storage tank 1 from the liquid inlet pipe 704 and the liquid outlet pipe 705. Due to the function of the water full automatic stop valve 703 itself, the water full automatic stop valve 703 can be automatically closed when the water in the water storage tank 1 is full, thereby preventing the upper layer of water from entering the water storage tank 1 when the water storage tank 1 is pulled ashore, resulting in mixing with the lower layer of water, affecting the accuracy of subsequent water source detection; After the collection is completed, the lifting rope 2 is pulled to pull the water tank 1 ashore. The water pressure corresponding to the water source in the water tank 1 can be observed through the transparent plate 3. The water source in the water tank 1 can be discharged for testing using the drain valve. The rack 415 is bolted to the water pressure push plate 413. After the water tank 1 is used, the rack 415 is removed from the water pressure push plate 413 so that the rack 415 is not meshed with the first gear 411. The pointer 417 is rotated in the same direction to reset it, or the position of the pointer 417 at this time is recorded. When the water tank 1 is used next time, the scale pointed by the pointer 417 next time is subtracted from the scale pointed by the pointer 417 before to obtain the water pressure this time.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
