[0036] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0037] The gate device for water flow signal monitoring of the present utility model is described below with reference to the accompanying drawings.

[0038] like Figures 1 to 4 As shown, the utility model provides a gate device for monitoring water flow signals, wherein the gate device for monitoring water flow signals includes:

[0039] The gate lifting mechanism comprises a door frame 1, a lifting driving member 2 and a gate plate 3, wherein the door frame 1 forms a gate door 10, the lifting driving member 2 is arranged on the door frame 1 and is used to drive the gate plate 3 to perform lifting movement to open or close the gate door 10, and an installation vertical plate 12 is arranged on the outer side of a column 11 of the door frame 1;

[0040] The monitoring module includes a non-contact liquid level meter 4 and a protective shell 5 for accommodating the non-contact liquid level meter 4. The protective shell 5 is arranged on the side of the mounting plate 12 facing the gate 10. The wiring terminal of the non-contact liquid level meter 4 is arranged close to the column 11. The wires 41 connected to the wiring terminal pass through the protective shell 5 and are arranged along the height direction of the mounting plate 12.

[0041] When the above-mentioned gate device for monitoring water flow signals is used, the monitoring module is fixed to the column 11 of the door frame 1 by installing the vertical plate 12, and the wire 41 is arranged along the vertical plate 12. The monitoring module will not hinder the water flow through the gate port 10, and can avoid the accumulation of debris in the water flow at the monitoring module, thereby ensuring the accuracy of liquid level detection; the monitoring module includes a protective shell 5 and a non-contact liquid level meter 4. When the gate releases water and the liquid level in the canal reaches the monitoring point of the monitoring module, the non-contact liquid level meter 4 can send a signal to the control module of the gate device. At the same time, the control module of the gate device can control the lifting drive 2 to drive the gate plate 3 to move according to the feedback signal, thereby realizing the monitoring of the canal liquid level. The non-contact liquid level meter 4 can avoid direct contact with the water flow through the protective shell 5, and will not be corroded due to water quality problems. It is suitable for long-term detection of the liquid level in outdoor waters.

[0042] Specifically, the non-contact liquid level meter 4 converts the dielectric constant into a capacitance value to judge the liquid level height based on the difference in dielectric constants between liquid and air. When the gate 3 is opened, the lifting drive 2 drives the gate 3 to move upward, and the water flows through the gate port 10. When the water flows through the non-contact liquid level meter 4, a high or low voltage signal or a spectrum signal will be output. This signal will be transmitted to the control module of the gate device through the wire 41, and the liquid level of the channel will be determined according to the signal.

[0043] Furthermore, a slide groove is formed on the opposite sides of the two uprights 11 of the door frame 1, and the gate plate 3 is movably arranged along the slide groove; the width of the slide groove is greater than the thickness of the gate plate 3, see Figure 5 A sealing strip 32 and a connecting plate 31 are also provided on the gate plate 3. The sealing strip 32 and the connecting plate 31 are respectively arranged on the front and rear sides of the gate plate 3 and are connected in series between the gate plate 3 and the side wall of the slide groove by bolts. The sealing strip 32 is set to an elastic material and is sealed against the side wall of the slide groove to prevent water from passing through the gap between the gate plate 3 and the column 11. In addition, the sealing strip 32 and the connecting plate 31 can block debris in the water. In the closed state, debris in the water will not accumulate in the slide groove, ensuring the smooth up and down movement of the gate plate 3; of course, an elastic sealing strip is also provided at the bottom of the door frame 1 to prevent water from passing through the bottom of the gate plate 3 in the closed state. Furthermore, the sealing strip 32 includes a first sealing portion, a connecting portion and a second sealing portion which are sequentially connected along the width direction of the gate plate 3. The first sealing portion and the second sealing portion are raised relative to the connecting portion to abut against the side wall of the slide groove, and the raised portions of the first sealing portion and the second sealing portion are both arranged to penetrate along the height direction. A pressure strip is arranged on the connecting portion. The bolts pass through the connecting plate 31, the gate plate 3, the connecting portion and the pressure strip of the sealing strip 32 in sequence. The nuts on the bolts are pressed against the pressure strip. The pressure strip is a hard material (such as metal) to avoid damage to the sealing strip 32 when tightening the bolts or nuts.

[0044] Furthermore, the lifting drive 2 includes a rotating motor and a screw pair, and the rotating motor drives the nut in the screw pair to rotate, thereby controlling the lifting and lowering of the screw in the screw pair. The screw is connected to the gate plate 3 through a connecting sleeve, and the connecting sleeve is connected to the screw through a fixing bolt. After loosening the fixing bolt, the connecting sleeve can swing to a certain extent relative to the screw to compensate for the position error of the gate plate 3 and / or the lifting drive 2 when the gate lifting mechanism is assembled, so as to avoid lateral load on the screw. Of course, the utility model is not limited to this, and the lifting drive 2 can also be set as a sprocket mechanism, and the motor drives the sprocket to rotate, thereby driving the gate plate 3 to move through the chain connected to the gate plate 3.

[0045] Furthermore, the installation plate 12 is spaced apart from the inner edge of the column 11 , and the protective housing 5 is arranged not to exceed the inner edge of the column 11 .

[0046] like Figure 3 and Figure 4 As shown, in the embodiment of the utility model, the protective housing 5 includes a detection part 51 and two mounting parts 52. The detection part 51 can be used to accommodate the non-contact liquid level meter 4, and the upper and lower sides of the first end 514 of the detection part 51 are provided with two mounting parts 52 corresponding to each other. The two mounting parts 52 are respectively connected to the mounting vertical plate 12 in a close fit. The second end 515 of the detection part 51 is arranged in a direction away from the column 11. The wiring terminal of the non-contact liquid level meter 4 is arranged at the first end 514 of the detection part 51, and the wire 41 is extended from the mounting part 52. Then the detection part 51 is parallel to the water flow direction, which can further prevent the accumulation of debris in the water at the monitoring module.

[0047] like Figure 2 and Figure 4 As shown, in the embodiment of the utility model, a disassembly opening is formed on the side of the detection part 51 facing the gate 10, and the protective shell 5 also includes a sealing plate 53, which is covered at the disassembly opening and enclosed with the detection part 51 to form a sealed space for accommodating the non-contact liquid level meter 4. The probe of the non-contact liquid level meter 4 is arranged toward the sealing plate 53 to ensure that the non-contact liquid level meter 4 can accurately detect the water flow through the gate 10. Specifically, the detection part 51 and the sealing plate 53 can be set to different thicknesses. The thickness of the detection part 51 is larger, which can effectively protect the non-contact liquid level meter 4. The thickness of the sealing plate 53 is smaller, so as to ensure that the detection signal of the non-contact liquid level meter 4 effectively passes through the sealing plate 53. Preferably, when the detection liquid is water, the thickness of the sealing plate 53 is preferably not more than 2 mm. For other detection liquids, the thickness of the sealing plate 53 can be adjusted according to the difference in the properties of the liquids.

[0048] like Figure 3 and Figure 4 As shown, in the embodiment of the utility model, a rib portion 516 is further provided on the inner wall of the detection portion 51, and the rib portion 516 can support the circuit board of the non-contact liquid level meter 4 to be arranged relative to the bottom wall of the detection portion 51, and the wiring terminal is located on the side of the circuit board facing the bottom wall of the detection portion 51, and the probe of the non-contact liquid level meter 4 is arranged toward the sealing plate 53. A supporting step 511 is also provided in the second end 515 of the detection portion 51, and the supporting step 511 is protruded from the bottom wall of the detection portion 51 toward the sealing plate 53. The non-contact liquid level meter 4 is clamped between the supporting step 511 and the sealing plate 53, and the internal space of the first end 514 of the detection portion 51 is used to connect the power line 41 with the wiring terminal of the non-contact liquid level meter 4.

[0049] like Figure 3As shown, in the embodiment of the utility model, the inner wall of the detection part 51 extends out to form a step surface 512, and the sealing plate 53 is attached to the step surface 512, and the outer side surface of the sealing plate 53 is set lower than the outer side surface of the detection part 51. After the sealing plate 53 is installed, a groove is formed on the end surface 513 of the protective shell 5. When debris with a certain volume and mass collides with the protective shell 5, it usually collides with the end surface 513, and it is difficult to directly hit the sealing plate 53, thereby forming protection for the sealing plate 53 and the non-contact liquid level meter 4.

[0050] In the embodiment of the utility model, a colloid filling medium is provided in the sealed space. Even if the protective shell 5 is damaged, the colloid filling medium can still play a role of sealing protection to prevent the liquid from contacting the non-contact liquid level meter 4. In addition, since the dielectric constant of air is easily affected by the environment (such as temperature), the colloid filling medium is introduced into the sealed space to achieve the effect of exhausting air and ensure the accuracy of the non-contact liquid level meter 4. Specifically, the colloid filling medium is set as a sealant. On the one hand, the sealant directly serves as an adhesive between the sealing plate 53 and the detection part 51. On the other hand, after the sealant is cured, it can also play the role of fixing the non-contact liquid level meter 4.

[0051] In the embodiment of the utility model, at least two positioning parts 121 are further provided on the side of the mounting plate 12 facing the gate 10, and the positioning parts 121 are sequentially arranged at intervals along the height direction of the mounting plate 12, and the wires 41 are fixed on the positioning parts 121. Specifically, the positioning parts 121 are configured as a frame structure, and the wires 41 are fixed to the positioning parts 121 by passing a cable tie. Of course, in other embodiments, the positioning parts 121 can also be configured as a buckle structure.

[0052] In the embodiment of the utility model, the gate device for monitoring water flow signals also includes a power supply module, which includes an electric control box 6 and a solar panel 7. The electric control box 6 is arranged at the top of the door frame 1. The electric control box 6 is provided with a motor of the lifting drive 2 and a gate device control module. The wire 41 is connected to the electric control box 6 and is electrically connected to the control module. The solar panel 7 is arranged on the electric control box 6 with an adjustable horizontal angle, and is used to supply power to the motor, the control module and the monitoring module. The electric control box 6 can play a role of waterproof and dustproof to protect the electrical components in the gate device, and the solar panel 7 can supply power to the electrical components in the electric control box 6 without an external power supply, which is suitable for outdoor waters; and according to the actual installation position of the gate device and the surrounding environment, the solar panel 7 can be horizontally rotated to ensure that it can receive sunlight with maximum efficiency. Specifically, a mounting frame is arranged on the lower side of the solar panel 7, and the mounting frame is provided with a circular connection hole, and a bolt for connecting the electric control cabinet is inserted into the connection hole. After loosening the bolt, the horizontal rotation mounting frame can be adjusted.

[0053] Furthermore, a signal transceiver module is also provided in the electrical control box 6, and the control module is communicatively connected to the signal transceiver module. The control module can directly control the lifting and lowering of the gate plate 3 according to the feedback data of the non-contact liquid level meter 4, and can also control the lifting and lowering of the gate plate 3 according to the control signal received by the signal transceiver module.

[0054] Furthermore, the mounting bracket is provided with a wiring hole for the cables of the solar panel 7 to pass through, and the lifting rod of the lifting drive member 2 is arranged opposite to the wiring hole.

[0055] In the embodiment of the utility model, the columns 11 are provided with mounting plates 12 on opposite sides along the water flow direction for the monitoring module to be installed, and the monitoring module can be optionally installed on the mounting plates 12 on the water outlet side. In actual scenarios, the water channel is generally set on the side of the road. In order to facilitate the operator to inspect the inside of the electric control cabinet, the lock of the electric control cabinet needs to be set on the side close to the road. If the mounting plate is set on only one side, the monitoring module may be set on the water inlet side of the gate. By setting the mounting plates 12 on both sides, the monitoring module can be installed on the water outlet side according to the actual situation.
