[0019] See also Figure 1-2, further illustrate the embodiments of the present utility model;

[0020] like Figure 1-2 As shown, a water flow direction monitoring device for hydrogeological survey includes a test box 1, a fixing ring 2 is fixed at the top center of the test box 1, a rope 3 is fixed on the fixing ring 2, and the rope 3 is used to lift the device. A pair of test rods 4 are rotatably connected to the test box 1, and the pair of test rods 4 are fixed with pointers 5. The rope 3 is equipped with a lifting device. When the device is used, the lifting device lowers the rope 3, so that the test box 1 and the pointer 5 are sunk into the water together. The test rod 4 and the pointer 5 will be deflected on the test box 1 due to the flow of water. After stabilization, the staff can know the direction of the water flow by observing the direction of the pointer 5.

[0021] A mounting post 14 is fixed at the center of the bottom of the test box 1, and a weighting member is sleeved on the mounting post 14. The weighting member includes a sponge 11 and two mounting plates 6 distributed up and down. The sponge 11 is installed between the two mounting plates 6. The upper mounting plate 6 and the sponge 11 are both sleeved on the mounting post 14. After the device enters the water, the sponge 11 will absorb water, thereby quickly increasing the weight of the device. The price of the sponge 11 is lower than that of the metal weight block, and the cost of making the device is also relatively lower. In order to make the upper mounting plate 6 more stable and movable, a guide rail pair can be set between the upper mounting plate 6 and the mounting post 14 so that the upper mounting plate 6 can be more stable and movable. The mounting plate 6 can slide stably on the mounting column 14 under the guidance of the guide rail pair, which is conducive to more uniform force on the sponge 11 and can extend the service life of the upper mounting plate 6 and the sponge 11. The lower mounting plate 6 is fixedly connected to the mounting column 14, and the lower mounting plate 6 plays a role in fixing and supporting the sponge 11. A pair of driving members are provided between the bottom of the test box 1 and the upper mounting plate 6. The driving member is used to drive the upper mounting plate 6 to move longitudinally, so that the two mounting plates 6 can squeeze the sponge 11, so that the volume of the sponge 11 can be greatly reduced, thereby reducing the water storage capacity of the sponge 11 and achieving the purpose of reducing the weight of the device.

[0022] The driving part specifically includes a sealing cover 9 and an electric push rod 10. The sealing cover 9 covers the outside of the electric push rod 10 and is fixed to the bottom of the test box 1. The output end of the electric push rod 10 passes through the sealing cover 9 and is fixedly connected to the upper mounting plate 6. The sealing cover 9 is provided to prevent water from entering the electric push rod 10. When the electric push rod 10 is working, it will drive the upper mounting plate 6 to move longitudinally to realize the sponge 11 rebounding to absorb water or the sponge 11 being pressed to drain water.

[0023] In order to facilitate the sponge 11 to quickly absorb water or dehydrate, a number of evenly distributed water holes 7 are opened on the surfaces of the two mounting plates 6. A limiting ring 8 is fixed on one side of the two mounting plates 6 close to the sponge 11, and the limiting ring 8 is used to limit the sponge 11.

[0024] In order to prevent impurities from adhering to the mounting post 14 when the sponge 11 moves, a protective member located above the weighting member is sleeved on the mounting post 14. The protective member includes two mounting rings 12 and a telescopic tube 13. The two mounting rings 12 are respectively fixed to the bottom of the test box 1 and the top of the upper mounting plate 6. The telescopic tube 13 is installed between the two mounting rings 12. When the upper mounting plate 6 moves, the telescopic tube 13 will cause elastic deformation. When the sponge 11 is compressed, the telescopic tube 13 will be stretched by the upper mounting plate 6 to cover the mounting post 14 exposed due to the compression of the sponge 11, so as to prevent impurities in the water from adhering to the mounting post 14, thereby extending the service life of the sponge 11.

[0025] When the device is in use, the initial state of the sponge 11 is the natural extension, such as Figure 2 As shown, the monitoring device is lifted to a designated location by a lifting device through a rope 3, and then the rope 3 is released. Since the sponge 11 does not absorb water when the monitoring device is lowered, the lifting device is subjected to less force, which is more labor-saving. The sponge 11 is a natural sponge with high density and a fully connected artificial sponge. After absorbing water, it will sink into the water. When the sponge 11 enters the water, it will absorb water. Since the density of the sponge will increase after it is full of water, it will sink, which increases the weight of the monitoring device, so as to prevent the monitoring device from floating laterally due to the influence of the water flow, which is conducive to more accurate testing of the monitoring device.

[0026] When the monitoring device is completely immersed in water, the test rod 4 and the pointer 5 will be deflected on the test box 1 due to the flow of water. After stabilization, the staff can know the direction of the water flow by observing the direction of the pointer 5;

[0027] After the test, when the device needs to be lifted, the electric push rod 10 is connected to the external power supply, and the electric push rod 10 will drive the upper mounting plate 6 to move downward, so that the two mounting plates 6 squeeze the sponge 11, so that a large amount of water in the sponge 11 is squeezed out. When the sponge 11 is about to be compressed to the limit, the power supply of the electric push rod 10 is turned off, so that the sponge 11 is continuously kept in the compressed state to prevent water from entering the sponge 11. At this time, the weight of the monitoring device is greatly reduced, which is conducive to the lifting device to quickly lift the monitoring device, greatly reducing the load of the lifting device; of course, a battery for powering the test rod 4 and the electric push rod 10 can also be installed in the test box 1, and a control module can be provided in the test box 1. The control module is electrically connected to the electric push rod 10, and the staff's mobile phone is connected to the control module through a wireless signal. The control module is controlled by the mobile phone to achieve the purpose of opening and closing the electric push rod 10;

[0028] When the upper mounting plate 6 moves, the telescopic tube 13 is elastically deformed. When the sponge 11 is compressed, the telescopic tube 13 is stretched by the upper mounting plate 6 to cover the mounting post 14 exposed by the compression of the sponge 11, thereby preventing impurities in the water from adhering to the mounting post 14 and extending the service life of the sponge 11.
