Description

Technical Field

[0001] The utility model relates to the technical field of groundwater level monitoring, in particular to a groundwater level monitoring device for ecological water level. Background Art

[0002] At present, in the process of monitoring groundwater level, most of the time, the water level meter is transmitted to the monitoring well by manually holding the transmission rope on the water level meter, which is very troublesome and inconvenient. In addition, in the process of long-term monitoring, in order to cover the well cover of the monitoring well, the transmission rope will generally extend into the monitoring well along the wall of the monitoring well, causing the water level meter to often be close to one side of the monitoring well. This phenomenon not only easily causes the water level meter to bump, but also easily affects the accuracy of the monitoring data.

[0003] Chinese patent application number: CN202220797623.6 discloses a water level monitoring device for monitoring groundwater level, including a monitoring water well, a transmission rope and a water level gauge, the upper end of the monitoring water well is exposed to the ground, and two semicircular manhole covers that can be opened are arranged on the wellhead of the monitoring water well, each semicircular manhole cover is provided with a semicircular hole, a pulley is arranged on the outer wall of the monitoring water well through a pulley frame, and a winch is arranged near the monitoring water well, one end of the transmission rope is wound on the drum of the winch, and the other end bypasses the pulley and passes through the two semicircular holes to extend into the monitoring water well; by setting the winch, the water level gauge can be taken and placed instead of manually, which is very convenient. In addition, the setting of the pulley can relatively set the transmission rope and the water level gauge at the center position of the wellhead, so as to avoid the transmission rope being attached to the inner wall of the monitoring water well, causing the wear of the transmission rope, the bump and wear of the water level gauge, and the inaccurate monitoring data caused by the water level gauge being too close to the inner wall of the monitoring water well.

[0004] From the above, it can be known that in order to prevent the water level meter from colliding with the inner wall of the monitoring well when pulling out the water level meter, a hole is opened in the center of the manhole cover in the prior art, so that the transmission rope pulls the water level meter upward to prevent the water level meter from fitting against the inner wall of the monitoring well. Although the water level meter is protected to a certain extent, the transmission rope needs to be reeled in slowly. If the reeling speed is too fast, the transmission rope may easily shake, thereby causing the water level meter to collide with the inner wall of the monitoring well, thereby limiting the speed at which the water level meter can be pulled up and down.

[0029] In the prior art, in order to prevent the water level meter from colliding with the inner wall of the monitoring well when pulling out the water level meter, a hole is opened at the center of the manhole cover, so that the transmission rope pulls the water level meter upward to prevent the water level meter from fitting with the inner wall of the monitoring well. Although the water level meter is protected to a certain extent, the transmission rope needs to be reeled in slowly. If the reeling speed is fast, the transmission rope is easy to shake, and then the water level meter collides with the inner wall of the monitoring well, which limits the speed of pulling the water level meter up and down. Therefore, after research, a groundwater level monitoring device for ecological water level is provided. When in use, an iron rod is set at the lower end of the rope, so that the second inner sleeve can be fixed on the iron rod, and the second hollow rod is slid out through the second extension rod, so that the roller contacts the inner wall of the monitoring well, increasing the weight of the water level meter, making the water level meter more stable under the pulling of the rope, not only avoiding the shaking of the water level meter when stretched, but also avoiding the collision of the water level meter with the inner wall of the monitoring well, thereby solving the above-mentioned defects.

[0030] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0031] Please refer to Figures 1 to 7 An embodiment of the utility model provides an ecological water level groundwater level monitoring device, including a monitoring well 1, a pair of fixed seats 22 are installed on the ground on both sides of the monitoring well 1, a retractable shaft 2 is rotatably arranged between the pair of fixed seats 22, the retractable shaft 2 is driven by a driving motor 21, a pull rope 3 is wound around the retractable shaft 2, and the lower end of the pull rope 3 is connected to a water level meter 6.

[0032] Among them, an iron rod 31 is set at the lower end of the pull rope 3, and two connecting buckles 32 are set at the lower end of the iron rod 31. The two connecting buckles 32 are in an "eight" shape. The two connecting buckles 32 are respectively connected to the two connecting rings 61 set on the upper side of the water level meter 6, thereby improving the stability of the water level meter 6 when being pulled by the pull rope 3.

[0033] The pull rope 3 near the water level gauge 6 is connected to the bottom anti-sway mechanism 5, and the bottom anti-sway mechanism 5 includes two second fixed sleeves 51 hinged on one side, and the other sides of the two second fixed sleeves 51 are connected by bolts, and one side of the second fixed sleeve 51 is connected to the second inner sleeve 52. The second fixed sleeve 51 and the second inner sleeve 52 are both semi-annular structures, and a pair is provided to be combined into a whole circle. A second through hole 53 is opened on one side of the second inner sleeve 52. The size of the second through hole 53 is adapted to the size of the iron rod 31, so that the lower end of the pull rope 3 can be fixed, and the weight of the lower end of the pull rope 3 is increased to keep the pull rope 3 stable.

[0034] At the same time, second hollow rods 54 are arranged on both sides of the two second fixed sleeves 51, and second extension rods 57 are slidably arranged in the two second hollow rods 54. The second extension rods 57 are pulled out to increase the length of the second hollow rods 54 and the second extension rods 57 so that the lengths are adapted to the diameter of the monitoring well 1.

[0035] A roller 58 is rotatably provided on one side of the second extension rod 57 so as to make the roller 58 contact with the inner wall of the monitoring well 1 , so that when the pull rope 3 is wound up, the roller 58 can move on the inner wall of the monitoring well 1 .

[0036] Furthermore, a screw rod 56 is rotatably set in each of the two second hollow rods 54. The screw rod 56 is driven by a micro motor 55. The micro motor 55 is located in the second hollow rod 54 to prevent it from contacting water. Since the screw rod 56 is threadedly connected to the second extension rod 57, when the screw rod 56 rotates, the second extension rod 57 can automatically slide out, avoiding the inconvenience of operating the second extension rod 57 at the bottom of the monitoring well 1.

[0037] Furthermore, an end anti-sway mechanism 4 is connected to the pull rope 3 close to the retracting shaft 2 , and the end anti-sway mechanism 4 is connected to the bottom anti-sway mechanism 5 through a limiting rod 7 .

[0038] Specifically, the end anti-sway mechanism 4 includes a pair of first inner sleeves 42 located on the outside of the pull rope 3. The outer sides of the two first inner sleeves 42 are respectively connected to the two first fixed sleeves 41. The first inner sleeve 42 and the first fixed sleeve 41 are both semi-annular structures, and one side of the two first fixed sleeves 41 is hinged, and the other sides of the two first fixed sleeves 41 are bolted. A first through hole 43 is opened on one side of the first inner sleeve 42 to allow the pull rope 3 to pass through the first through hole 43. The size of the first through hole 43 is larger than the size of the pull rope 3, and the pull rope 3 can move up and down in the first inner sleeve 42.

[0039] Furthermore, a first hollow rod 44 is provided on one side of the first fixed sleeve 41, and a first extension rod 45 is slidably provided in the first hollow rod 44, and the first extension rod 45 is pulled out. Since a clamping plate 46 is provided on one side of the first extension rod 45, the clamping plate 46 has a "U"-shaped structure and can be clamped on the edge of the monitoring well 1, thereby fixing the entire end anti-sway mechanism 4 at the upper end of the monitoring well 1.

[0040] Furthermore, a first through ring 47 is provided on one side of the first extension rod 45, and a second through ring 59 is provided on one side of the second extension rod 57. The limiting rod 7 is passed from the first through ring 47 to the second through ring 59, and the upper end of the limiting rod 7 is threadedly connected to the nut, so that the limiting rod 7 is vertically fixed on the first extension rod 45, and the second through ring 59 is slidably connected to the limiting rod 7. When the pull rope 3 is wound, the second extension rod 57 moves upward and slides on the limiting rod 7 through the second through hole 53, so that the stability of the pull rope 3 is further enhanced by the limiting rod 7.

[0041] It is worth mentioning that a pair of semi-circular manhole covers 11 are arranged on the upper side of the monitoring well 1, and a gap 12 is opened in the center of the pair of manhole covers 11. After the two semi-circular manhole covers 11 are merged, the two gaps 12 form an annular gap 12, so that the pull rope 3 can pass through, and a slot 13 is opened at the edge of the manhole cover 11, and the slot 13 can expose the card plate 46.

[0042] In summary, the working principle of an ecological water level groundwater level monitoring device of an embodiment of the utility model is as follows: an iron rod 31 is set at the lower end of the pull rope 3, so that the second inner sleeve 52 can be fixed on the iron rod 31, and the second hollow rod 54 is slid out through the second extension rod 57, so that the roller 58 contacts the inner wall of the monitoring well 1, and the weight of the water level meter 6 is increased, so that the water level meter 6 is more stable under the pulling of the pull rope 3, and at the same time, combined with the limitation of the limit rod 7, the second extension rod 57 and the second hollow rod 54 are slid on the limit rod 7 to further prevent the water level meter 6 from colliding.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
