Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0027] As Figure 1 shown:

[0028] A water level detection device for water conservancy construction comprises a base 101.

[0029] In the present embodiment: the existing device {publication (announcement) number}: CN220152388U discloses a water level detection device for water conservancy construction, in order to solve the technical problems existing in the prior art, as disclosed in the background art above, "the above design can stabilize the device when in use, although the electric push rod is extended to drive the stable pad to move, thereby playing a stabilizing role, but the electric telescopic rod drives the detection ruler to descend into the water, and when the water level continuously moves upward, it cannot timely send an alarm, and cannot realize the function of real-time reminding, which is easy to cause equipment damage and production accidents due to high water level", in combination with use, this problem is obviously a real problem and is relatively difficult to solve, the electric power equipment involved in the product is powered by an external power source, and the scheme further provides an electric control cabinet, which is arranged on the equipment. When in use, each electric device can be started by the electric control cabinet, and the power connection mode of each electric device is a mature technology known to those skilled in the art, and will not be described in detail here.

[0030] Further:

[0031] As shown in Figures 1-4 :

[0032] In combination with the above content: the upper side of the base 101 is provided with a cross beam rod 103, one end of the cross beam rod 103 is slidably provided with a rod body 104;

[0033] One end of the rod body 104 is provided with a floating plate 105;

[0034] The floating plate 105 is fixedly installed with a silica gel sleeve 106 through the installation hole formed in the inside of the floating plate 105, and the inner diameter of the silica gel sleeve 106 is inserted into the surface of the rod body 104 in an interference fit;

[0035] The bottom end of the cross beam rod 103 is fixedly installed with a laser ranging sensor 107 corresponding to the floating plate 105 through the installation hole formed therein;

[0036] The cross beam rod 103 is fixedly installed with an alarm 108 on one side, and the cross beam rod 103 is installed with a storage battery;

[0037] The upper surface of the base 101 is fixedly provided with a top rod 102, and the cross beam rod 103 is fixedly installed at one end of the top rod 102. A circular hole is formed in the position of the outer surface of the cross beam rod 103 close to the rod body 104, and a plurality of groups of ball bearings 109 are arranged in the circular hole in a symmetrical arrangement. The plurality of groups of ball bearings 109 can be installed by rolling in the annular groove formed in the cross beam rod 103. Through the arrangement of the ball bearings 109, the friction between the rod body 104 and the cross beam rod 103 is reduced.

[0038] In the embodiment, the inner hole of the silica gel sleeve 106 is inserted on the rod body 104 in an interference fit, so as to fix the silica gel sleeve 106 on the rod body 104 and provide support for the installation of the floating plate 105. Then, the base 101 is inserted at the riverbed slope, and one end of the cross beam 103 and the floating plate 105 are located at the riverbed. At this time, the floating plate 105 falls on the water and floats on the water surface. When the water level rises, the floating plate 105 floating on the water surface drives the rod body 104 to move upward continuously. The laser ranging sensor 107 emits laser pulses or continuous waves to the target floating plate 105. When the laser hits the floating plate 105, it is partially reflected back. The laser ranging sensor 107 continuously monitors the distance of the target floating plate 105. If the floating plate 105 is rising, there is a predetermined distance threshold in the setting of the laser ranging sensor 107. When the floating plate 105 moves upward to reach or exceed this threshold, the alarm 108 is triggered. The alarm 108 is an audible and light alarm for alerting the operator;

[0039] The laser ranging sensor 107 monitors the water level in real time. When the water level rises, the system can quickly capture the distance change and issue an alarm in time to ensure the real-time and accuracy of water level monitoring. It reminds the operator or the automatic system to take appropriate measures to avoid equipment damage, production accidents or personnel casualties caused by high water level, greatly improving the safety of the production process.

[0040] The cross beam 103 is provided with a ball 109, so that the rod body 104 can reduce the friction between the rod body 104 and the cross beam 103 while sliding on the cross beam 103, and improve the smoothness of the movement of the rod body 104.

[0041] It should be noted that the cross beam 103 is provided with a battery to provide power for the laser ranging sensor 107 and the alarm 108.

[0042] Further,

The surface of the contact rod 110 is provided with a spring 111. The two ends of the spring 111 are fixedly connected with the contact rod 110 and the cross beam 103, respectively. In the initial state of the spring 111, one end of the contact rod 110 is separated from the rod body 104.

[0044] In this embodiment: when the length of the spliced rod body 104 is too long to be inconveniently moved to the middle part of the riverbed, the one end of the spliced rod body 104 is inserted into the circular hole, and the silica gel sleeve 106 on the floating plate 105 is inserted into the surface of the rod body 104, while the pressing rod 110 is pressed to compress the spring 111, and the pressing rod 110 is pressed on the surface of the rod body 104, so that the rod body 104 is temporarily extruded and locked on the cross beam rod 103. Turn the device by a certain angle, and displace the one end of the cross beam rod 103 and the rod body 104 above the riverbed, then release the pressing rod 110, at this time the spring 111 rebounds and drives the pressing rod 110 to reset, so that the pressing rod 110 is separated from the rod body 104, thereby releasing the extrusion of the rod body 104. At this time, the rod body 104 slides downward on the cross beam rod 103 by its own weight, and falls on the horizontal plane towards the floating plate 105.

[0045] Further more;

[0046] In an optional embodiment, the rod body 104 can be provided with multiple groups, and the rod body 104 is provided with a splicing assembly 2, which includes a plug column 201 fixed at one end of the rod body 104 and a strong magnet I 202 fixed at one end of the plug column 201.

[0047] The other end of the rod body 104 is provided with a plug slot 203 matched with the plug column 201, and the plug slot 203 is provided with a strong magnet II 204, and the strong magnet II 204 is fixedly connected with the rod body 104.

[0048] In this embodiment: when the height from the slope surface to the horizontal plane is greater than the height of the rod body 104, it is difficult for the floating plate 105 on the rod body 104 to reach the horizontal plane, so that the splicing assembly 2 is used to splice multiple rod bodies 104 to extend to a certain height. The plug column 201 on one group of rod bodies 104 is inserted into the plug slot 203 of another group of rod bodies 104. Since the strong magnet I 202 is fixedly connected with the plug column 201, and the strong magnet II 204 is fixed in the plug slot 203, when the plug column 201 is inserted into the plug slot 203, the strong magnet I 202 and the strong magnet II 204 contact each other, and the two sides of the strong magnet I 202 and the strong magnet II 204 in contact with each other are opposite magnetic poles, thereby achieving splicing of the two groups of rod bodies 104 through magnetic adsorption, so as to better meet the use requirements of the device.

[0049] It should be noted that: the rod body 104 can be made of polyethylene plastic material to make the weight of the rod body 104 lighter.

[0050] It should be understood that:
