Description

Technical Field

[0001] This utility model belongs to the technical field of water conservancy engineering equipment, specifically relating to a water level detection device for water conservancy engineering. Background Technology

[0002] Traditional methods for monitoring water levels in hydraulic engineering projects mainly rely on manual observation, such as marking water level warning lines on the side walls of dams or setting up fixed markers. While these methods are simple in structure and low in cost, they have practical problems. They require staff to regularly visit the site for visual inspections or manual measurements, which is not only inefficient but also increases labor intensity and costs. Especially in inclement weather or at night, manual observation is difficult to implement, making it difficult to detect abnormal water levels in a timely manner. Utility Model Content

[0003] This application proposes a water level detection device for water conservancy projects, which can be used to detect water levels and improve the convenience of water level detection.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A water level detection device for water conservancy projects includes a base, a support column on the upper surface of the base, first connecting blocks on both sides of the support column, a first mounting plate connected to the side of the first connecting blocks, a first mounting bracket connected to the side wall of the first mounting plate, a receiving cavity mounted on the upper end of the first mounting bracket, a through hole on the bottom surface of the receiving cavity, an elastic membrane covering the through hole to keep the receiving cavity in a sealed state, a pressure sensor disposed inside the receiving cavity above the elastic membrane, a float disposed below the through hole of the receiving cavity, a processing device and a signal transmitting device disposed inside the receiving cavity, the pressure sensor being electrically connected to the processing device, and the processing device being electrically connected to the signal transmitting device.

[0005] In one embodiment of this application, a height adjustment device is provided at the connection between the first mounting plate and the first mounting bracket. The height adjustment device includes a threaded post inserted into the top of the first mounting plate. The threaded post is screwed into a threaded hole at the upper end of the movable plate. The first mounting bracket is connected to the side of the movable plate.

[0006] In one embodiment of this application, a guide rod is connected to the bottom end of the float, and the guide rod is inserted into a guide hole on the upper end face of the support column.

[0007] In one embodiment of this application, a protective plate is provided on the outside of the float, and the protective plate is connected to the two sides of the first mounting plate.

[0008] In one embodiment of this application, the first mounting bracket is provided with fixing holes on both sides.

[0009] In one embodiment of this application, a support rod is provided at the upper end of the support column.

[0010] In one embodiment of this application, a drill rod is inserted into the side wall of the base.

[0011] In summary, the technical solution proposed in this application has the following beneficial technical effects: This application utilizes a float that rises upon contact with water, allowing its upper end to insert into a through hole. An elastic diaphragm then presses against the pressure sensor. Specifically, when the water level rises to the float's position, the float rises and inserts into the through hole at the bottom of the receiving cavity, pushing the elastic diaphragm upwards and compressing the pressure sensor to generate a signal. The pressure sensor is connected to a signal transmitting device via a processing device. When the pressure sensor senses the pressure transmitted by the float pushing the elastic diaphragm, it transmits a signal to the processing device. The processing device then controls the signal transmitting device to transmit a wireless signal to the water conservancy monitoring room, indicating that the water level has been detected and the detection device has reached its deployment location. This eliminates the need for manual on-site observation, enabling 24 / 7 unattended operation, reducing the burden on staff, and improving the timeliness and convenience of water level detection information transmission.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0016] It should be noted that in the description of this application, the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art will understand the specific meaning of these terms in this application based on the specific circumstances.

[0018] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0019] This embodiment provides a water level detection device for water conservancy projects, see reference. Figures 1-5As shown, the device includes a base 1, a support column 11 on the upper surface of the base 1, first connecting blocks 2 on both sides of the support column 11, a first mounting plate 3 connected to the side of the first connecting block 2, a first mounting bracket 4 connected to the side wall of the first mounting plate 3, a receiving cavity 5 mounted on the upper end of the first mounting bracket 4, a through hole 51 opened on the bottom surface of the receiving cavity 5, an elastic membrane 511 covering the through hole 51 to keep the receiving cavity 5 in a sealed state, a pressure sensor 52 disposed in the receiving cavity 5, the pressure sensor 52 disposed above the elastic membrane 511, a float 6 disposed below the through hole 51 of the receiving cavity 5, a processing device and a signal transmitting device disposed in the receiving cavity 5, the pressure sensor 52 being electrically connected to the processing device, and the processing device being electrically connected to the signal transmitting device.

[0020] In the above embodiment, the base 1 is set at the bottom of the device to support the device. The upper surface of the base 1 is provided with a support column 11. The support column 11 is provided with a first connecting block 2 on both sides. The first connecting block 2 is connected to a first mounting plate 3 on its side. The side wall of the first mounting plate 3 is connected to a first mounting bracket 4. The upper end of the first mounting bracket 4 is provided with a receiving cavity 5. The bottom surface of the receiving cavity 5 is provided with a through hole 51. The through hole 51 is covered with an elastic membrane 511, so that the receiving cavity 5 is in a sealed state. The mechanical triggering method of the float 6 and the elastic membrane 511 avoids the electronic sensor from directly contacting the water body, reducing the impact of factors such as silt and biological attachment on the detection accuracy. A pressure sensor 52 is installed inside the receiving cavity 5, positioned above the elastic membrane 511. A float 6, a hollow cavity, is located below the through-hole 51 of the receiving cavity 5. The float 6 rises when exposed to water. When the water level reaches the position of the float 6, it floats upwards, causing its upper end to insert into the through-hole 51. This pressure is applied to the pressure sensor 52 through the elastic membrane 511. Specifically, when the water level reaches the position of the float 6, it rises and inserts into the through-hole 51 at the bottom of the receiving cavity 5, pushing the elastic membrane 511 upwards and compressing the pressure sensor 52 to generate a signal. The pressure sensor 52 is connected to a signal transmitting device via a processing device. When the pressure sensor 52 senses the pressure transmitted by the float 6 pushing the elastic membrane 511, it transmits a signal to the processing device. The processing device then controls the signal transmitting device to send a wireless signal to the water conservancy monitoring room, indicating that the water level has been detected and the detection device has reached its deployment location. This eliminates the need for manual on-site observation, enabling 24 / 7 unattended operation, significantly reducing the workload of staff, and improving the timeliness and accuracy of water level detection information transmission. In addition, when the water level drops, the float 6 detaches from the through hole 51 under the action of gravity, the elastic membrane 511 returns to its original state, the pressure signal disappears, and the control signal transmitter of the processing device transmits a wireless signal to the water conservancy monitoring room, indicating that the water level has dropped from the deployment position. When in use, the detection device is deployed at key detection positions to realize the rise and fall of the water level at the control point.

[0021] In one embodiment of this application, see [reference] Figure 3 As shown, a height adjustment device 7 is provided at the connection between the first mounting plate 3 and the first mounting bracket 4. The height adjustment device 7 includes a threaded post 71 inserted into the top of the first mounting plate 3. The threaded post 71 is screwed into the threaded hole at the upper end of the movable plate 72. The first mounting bracket 4 is connected to the side of the movable plate 72.

[0022] In the above embodiment, the threaded post 71 is screwed into and out of the threaded hole at the upper end of the movable plate 72 to adjust the distance between the top of the movable plate 72 and the top of the first mounting plate 3. The movable plate 72 is connected to the top of the first mounting plate 3 through the threaded post 71. When the threaded post 71 is screwed into the movable plate 72, the distance between the top of the movable plate 72 and the top of the first mounting plate 3 decreases, and the movable plate 72 rises. Similarly, when the threaded post 71 is screwed out of the movable plate 72, the distance between the top of the movable plate 72 and the top of the first mounting plate 3 increases, and the movable plate 72 falls. This, in turn, drives the first mounting frame 4 to move up and down, thereby adjusting the vertical setting height of the receiving cavity 5. This allows the position of the receiving cavity 5 to be adjusted according to the size of the float 6 (because the size of the float 6 directly affects the height of its trigger point), or to adapt to different water surface measurement positions. This is beneficial to improving the adaptability of the detection device. In scenarios where it is necessary to temporarily change the monitoring water level level (such as different warning water levels during flood season and non-flood season), staff can quickly adjust it on-site, enabling the device to dynamically respond to different monitoring tasks.

[0023] In one embodiment of this application, see [reference] Figure 2 As shown, the bottom end of the float 6 is connected to a guide rod 61, which is inserted into the guide hole 111 on the upper end face of the support column 11.

[0024] In the above embodiment, the cooperation between the guide rod 61 and the guide hole 111 restricts the movement of the float 6 to the vertical direction, preventing the float 6 from drifting horizontally under the action of water flow, waves, or wind. This ensures that the float 6 can be aligned with and inserted into the through hole 51 at the bottom of the receiving cavity 5 when it floats up, reliably triggering the pressure sensor 52 and avoiding detection failure caused by misalignment of the float 6.

[0025] In one embodiment of this application, see [reference] Figure 1 As shown, a protective plate 8 is provided on the outside of the float 6, and the protective plate 8 is connected to both sides of the first mounting plate 3.

[0026] In the above embodiment, the protective plate 8 acts as a barrier to enclose the float 6 between the protective plates 8, preventing the float 6 from being washed away by the water, and is used to block floating objects on the water surface from hitting the float 6, thereby improving the stability of the float 6.

[0027] In one embodiment of this application, see [reference] Figure 3As shown, the first mounting bracket 4 has fixing holes 41 on both sides.

[0028] In the above embodiments, by inserting a rod or pin into the socket, inserting the rod into the grooves on both sides of the float 6, or by binding the float 6 with a cable tie through the fixing socket 41, the float 6 is temporarily fixed, which facilitates the installation of the detection device and the stability of the float 6 when the detection device is transported.

[0029] In one embodiment of this application, see [reference] Figure 4 As shown, a support rod 112 is provided at the upper end of the support column 11.

[0030] In the above embodiment, in the initial state, the top end of the support rod 112 is supported on the bottom end of the float 6 to support the bottom of the float 6. During long periods of no water or low water level, that is, when there is no need to detect the water surface, the float 6 can be lifted off the water surface to prevent the float 6 from being soaked in water for a long time and aging faster, and to improve the stability of the float 6 when it is stationary.

[0031] In one embodiment of this application, see [reference] Figure 1 As shown, a drill rod 12 is inserted into the side wall of the base 1.

[0032] In the above embodiment, the base 1 is firmly connected to the ground by the rod 12, which improves the stability of the device on soft ground (such as muddy riverbanks and sandy soil), and can resist the tilting or falling caused by wind, water flow impact and accidental collision, ensuring reliable deployment for long-term monitoring.

[0033] In the actual use of this application: Equipment selection: The pressure sensor 52 can be a miniature pressure sensor 52 from the prior art; the processing device is an MCU microcontroller; the signal transmitting device is a SIM800C GSM module that supports SMS and TCP / IP data transmission; the float 6 is made of hollow polyethylene; when the water level rises to the position of the float 6, the float 6 floats up and presses against the elastic membrane 511, the pressure sensor 52 outputs an electrical signal, and the processing device receives the electrical signal from the pressure sensor 52. For example, the control GSM module sends an alarm SMS message "water level has reached the warning line" to the monitoring center; after the water level drops, the float 6 falls back, the pressure signal disappears, and the system sends a status message "water level has returned to normal". The staff at the monitoring center record the water level information to achieve real-time detection of the controlled water level.

[0034] In addition, a battery pack is installed inside the cavity to power the operation of the electrical components.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
