Description

Technical Field

[0001] This utility model relates to the field of water level monitoring technology, specifically to an electronic device for water level monitoring. Background Technology

[0002] Water level refers to the elevation of the free water surface relative to a certain datum. The datum used to calculate the water level can be a characteristic sea level elevation at a certain location as the zero-point leveling datum, which is called the absolute datum. Water level is the most direct factor reflecting the water condition of a water body, and its changes are mainly caused by the increase or decrease in the water volume.

[0003] Utility model patent CN216206862U discloses a water level monitoring device for water conservancy and hydropower projects. It solves the problem that current water level monitoring devices in water conservancy and hydropower projects simply use a water level bar installed in the water, judging the water level by observing the scale line corresponding to the float on the bar. However, in actual operation, the water level bar is easily affected by water surface fluctuations, resulting in errors in the read water level data, affecting the accuracy of the water level parameters. Furthermore, it lacks water level warning functions and has overly simplistic functionality. This new device uses an electronic sensor to monitor a float floating on the inner wall of the water level bar, and then connects it via an electrical connection... The display screen intuitively shows the water level data, and the device uses a three-color warning light to monitor the rise and fall of the water level. This avoids errors in the water level data read due to the water level rod being easily affected by water surface fluctuations, which would affect the accuracy of the water level parameters and the absence of a water level warning function. However, in actual use, the above patent utilizes the principle of communicating vessels to ensure that the water level in the water source and the water level in the water level rod are at the same height. But in actual use, impurities in the water source may adhere to the surface of the filter screen, causing the filter screen to become clogged. This would prevent the external water source from quickly entering or leaving the water level rod, or even prevent it from entering or leaving the water level rod altogether, thus reducing the accuracy of the device's detection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electronic water level monitoring device, comprising a water level rod, a filter cylinder fixedly connected to the bottom of the water level rod, the bottom of the filter cylinder being closed, filter holes being formed on the surface of the filter cylinder, the number of filter holes being several, the filter holes being evenly distributed on the surface of the filter cylinder, a first arc-shaped frame and a second arc-shaped frame being respectively provided on the outside of the filter cylinder, the first arc-shaped frame and the second arc-shaped frame being fixedly connected by a first bolt, elastic bristles being fixedly connected to the surface of both the first arc-shaped frame and the second arc-shaped frame, the number of elastic bristles being several, the elastic bristles being in contact with the filter cylinder, a sliding groove being provided on the surface of the water level rod, and a movable frame being slidably connected inside the sliding groove, a fixing block being fixedly connected to the top of both the first arc-shaped frame and the second arc-shaped frame, the fixing block being fixedly connected to the movable frame by a second bolt.

[0006] As a preferred embodiment of this utility model, a mounting bracket is fixedly connected to the surface of the water level rod, an electric cylinder is fixedly connected to the top of the mounting bracket, and the output end of the electric cylinder is fixedly connected to the movable frame.

[0008] As a preferred embodiment of this utility model, the bottom of the observation box is fixedly connected to an installation plate, and the surface of the installation plate is provided with several installation openings.

[0009] As a preferred embodiment of this invention, a filter screen is fixedly connected to the top of the water level rod by a third bolt.

[0010] As a preferred embodiment of this utility model, the surfaces of the electric cylinder and the observation box are both fixedly connected with reinforcing frames, which are respectively fixedly connected to the mounting frame and the support column.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model employs a filter cylinder with perforations at the bottom of the water level bar, combined with a first arc-shaped frame, a second arc-shaped frame, and an elastic brush structure.

This significantly reduces the frequency of filter cylinder clogging, ensuring that the water level in the water level bar is synchronized with the water source level in real time. This greatly improves the accuracy and reliability of water level monitoring data, and the device has the advantage of high detection accuracy.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 4As shown, an electronic water level monitoring device includes a water level rod 1, a filter cylinder 2 fixedly connected to the bottom of the water level rod 1, the bottom of the filter cylinder 2 being closed, filter holes 3 evenly distributed on the surface of the filter cylinder 2, a first arc-shaped frame 4 and a second arc-shaped frame 5 respectively provided on the outside of the filter cylinder 2, the first arc-shaped frame 4 and the second arc-shaped frame 5 being fixedly connected by a first bolt, elastic bristles 6 fixedly connected to the surface of both the first arc-shaped frame 4 and the second arc-shaped frame 5, the elastic bristles 6 being in contact with the filter cylinder 2, a sliding groove provided on the surface of the water level rod 1, and a movable frame 8 slidably connected inside the sliding groove, a fixing block 7 fixedly connected to the top of both the first arc-shaped frame 4 and the second arc-shaped frame 5, the fixing block 7 being fixedly connected to the movable frame 8 by a second bolt, and a float and an electronic device respectively provided inside the water level rod 1. The sensor and the observation box 11 are respectively equipped with a display screen and a warning light. Utilizing the principle of communicating vessels, the water level inside the water level rod 1 is the same as the water level of the water source. The electronic sensor monitors the float floating on the inner wall of the water level rod 1, and the water level data is displayed intuitively on the display screen connected by electricity. The device also uses a three-color warning light to monitor the rise and fall of the water level. This avoids the water level data reading errors caused by the water level rod 1 being easily affected by water surface fluctuations, which would affect the accuracy of the water level parameters and the absence of a water level warning function. The water level rod 1, observation box 11, electronic sensor and float mentioned above are similar in principle to the water level rod, observation box, electronic sensor and float mentioned in the utility model patent disclosed in CN216206862U, which is a water level monitoring device for water conservancy and hydropower projects, and achieve the same effect. This application will not elaborate further.

[0021] refer to Figure 1 A mounting bracket 9 is fixedly connected to the surface of the water level rod 1, and an electric cylinder 10 is fixedly connected to the top of the mounting bracket 9. The output end of the electric cylinder 10 is fixedly connected to the movable frame 8.

[0022] As a technical optimization of this utility model, by setting up the mounting frame 9 and the electric cylinder 10, the extension or retraction of the electric cylinder 10 can drive the movable frame 8 to move down or up, thereby driving the first arc frame 4, the second arc frame 5 and the elastic bristles 6 to move down or up.

[0023] refer to Figure 1 An observation box 11 is provided on the right side of the water level rod 1. A support column 12 is fixedly connected to the left side of the observation box 11. A groove is provided on the left side of the support column 12. The mounting bracket 9 is slidably connected to the groove. A slot is provided on the top of the mounting bracket 9. There are several slots. A screw 13 is threaded inside the support column 12. The screw 13 is inserted into the slot. The surface of the screw 13 is coated with anti-rust paint.

[0024] As a technical optimization of this utility model, by setting up the observation window, support column 12, groove, slot and screw 13, the operator can move the mounting frame 9 left and right, thereby adjusting the distance between the water level rod 1 and the observation box 11. When the mounting frame 9 and the water level rod 1 move to the appropriate distance, the operator tightens the screw 13 so that the screw 13 is inserted into the slot, thereby locking the position of the mounting frame 9 and the water level rod 1.

[0025] refer to Figure 1 The bottom of the observation box 11 is fixedly connected to a mounting plate 15, and the surface of the mounting plate 15 is provided with mounting openings 16, and the number of mounting openings 16 is several.

[0026] As a technical optimization of this utility model, the device can be stably installed by bolts through the setting of the mounting plate 15 and the mounting port 16.

[0027] refer to Figure 1 A filter screen 17 is fixedly connected to the top of the water level rod 1 by a third bolt.

[0028] As a technical optimization of this utility model, by setting the filter screen 17, the top of the water level rod 1 needs to be set as an opening to maintain the air pressure inside the water level rod 1 the same as the outside air pressure. By setting the filter screen 17, impurities in the external environment can be prevented from falling into the water level rod 1 and affecting the normal operation of the water level rod 1.

[0029] refer to Figure 1 The surfaces of the electric cylinder 10 and the observation box 11 are both fixedly connected to a reinforcing frame 14, which is fixedly connected to the mounting frame 9 and the support column 12 respectively.

[0030] As a technical optimization of this utility model, the installation stability of the electric cylinder 10 and the support column 12 can be improved by setting the reinforcing frame 14, thereby improving the stability of the device.

[0031] The working principle and usage process of this utility model are as follows: When in use, the water level inside the water level rod 1 is the same as the water level of the water source, based on the principle of communicating vessels. Then, the float floating in the inner wall of the water level rod 1 is monitored by an electronic sensor. The water level data is displayed intuitively on the display screen connected by electricity, and a three-color warning light is used to monitor the rise and fall of the water level. This device avoids errors in the water level data read due to the water level rod 1 being easily affected by water surface fluctuations.

[0032] When the filter holes 3 on the surface of the filter cylinder 2 are blocked by impurities, water in the water source may not be able to quickly enter or exit the filter cylinder 2, or may not be able to enter or exit the filter cylinder 2 at all. At this time, the measurement accuracy of the device is low. The operator can adjust the extension or retraction of the electric cylinder 10, which in turn drives the movable frame 8 to move down or up, and in turn drives the first arc frame 4, the second arc frame 5 and the elastic bristles 6 to move down or up. The elastic bristles 6 can sweep away most of the impurities accumulated on the surface of the filter cylinder 2, thereby reducing the frequency of the filter cylinder 2 being blocked to a certain extent. The movable frame 8 slides stably up and down in the slide groove. The operator can remove the second bolt, thereby separating the movable frame 8 from the first arc frame 4 and the second arc frame 5 respectively. Then remove the first bolt, thereby separating the first arc frame 4 from the second arc frame 5. At this time, the operator can maintain or replace the first arc frame 4 or the second arc frame 5. This device adopts the linkage design of the electric cylinder 10 and the movable frame 8, which not only realizes the automatic cleaning of the filter cylinder 2 by the elastic bristles 6, but also makes the maintenance work more convenient. When maintenance or replacement of the cleaning components is required, the movable frame 8, the first arc frame 4 and the second arc frame 5 can be quickly separated simply by removing the second bolt and the first bolt, which greatly shortens the maintenance time and reduces the maintenance cost.
