The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] A monitoring device based on a static level 2, such as Figure 1-Figure 2As shown, it includes a liquid storage tank 1 for storing liquid, a plurality of static levels 2 connected in series through a pipe group, and a plurality of displays 6 respectively connected to each of the static levels 2, and the displays 6 are used to display data detected by the static levels 2;

[0024] The static level 2 at the head end is connected to the lower part of the liquid storage tank 1 through a first water pipe 3, the static level 2 at the head end is connected to the upper part of the liquid storage tank 1 through a first air pipe 4, and the static level 2 at the end end is connected to the first air pipe 4 through a second air pipe 5.

[0025] Among them, the working principle of the static level 2 is as follows: the static level 2 has a built-in metal film isolated silicon pressure sensor, the measured pressure acts directly on the isolation diaphragm, and the piezoresistive effect of the semiconductor silicon material is utilized to realize the linear conversion between pressure and electrical signal through the Wheatstone bridge on the silicon sensitive chip. The signal is processed by a dedicated signal processing circuit to form a standard signal output. Since the static level 2 is a prior art, no further details are given here. The number of static levels 2 can be freely set according to the points to be detected. In this embodiment, the number of static levels 2 is set to three. In other embodiments, the number of levels can be increased or decreased according to the points to be measured.

[0026] The present invention connects a display 6 to each measuring point, that is, each static level 2, so that the data obtained by the static level 2 can not only be presented in the background, but also when the maintenance personnel arrive at the site, they can view the liquid level value and original pressure of the measuring point through the display 6 on each static level 2. At the same time, they can also view historical data including the liquid level value and the original pressure of the equipment on the display 6, and at the same time show which point in the entire waterway is in a negative pressure state, thereby avoiding human errors and subjective judgments, and achieving more accurate monitoring and management. At the same time, different colors of lights are used to display the current status of the measuring point. If the point is in a normal operating state, the status can be displayed in a constantly bright green color, that is, green is displayed on the display 6; if the point has a negative pressure status, a red flashing prompt can be used on the display 6 to inform the maintenance personnel that the pressure here is negative and timely maintenance is required; thus, the maintenance personnel can directly see the detailed data of each measuring point on the on-site display 6, so that even in a complex engineering environment, they can quickly obtain the necessary information, speed up fault diagnosis and processing, and improve manual safety: and the display 6 can promptly detect and mark the measuring points with abnormal pressure, help avoid possible safety accidents, and improve the safety of manual maintenance; reduce manual inspection: and the display 6 shows the operating status of the current measuring point, which can more intuitively understand the information of the current measuring point, reducing the need for manual point-by-point inspection, especially in environments with limited vision or space. This advantage is particularly obvious.

[0027] Furthermore, the static level 2 includes a level body 21, a first air path connection joint 22 and a second air path connection joint 23, a first water path connection joint 24 and a second water path connection joint 25, and a first circuit connection joint 26 and a second circuit connection joint 27 respectively arranged on both sides of the level body 21; the first water path connection joint 24 of the static level 2 at the head end is connected to the lower part of the liquid storage tank 1 through the first water path pipe 3, and the first air path connection joint 22 of the static level 2 at the head end is connected to the liquid storage tank The upper parts of the tanks 1 are connected by the first air path pipe 4; the second air path connecting joint 23 of the end of the static level 2 is connected to the first air path pipe 4 by the second air path pipe 5; the pipeline group includes a circuit connection line 7, a second water path pipe 8 and a third air path pipe 9, the circuit connection line 7 is used to transmit the data obtained by each static level 2 to each other, the second water path pipe 8 is used to connect the water path of each static level 2, and the third air path pipe 9 is used to connect the air path of each static level 2.

[0028] It can be understood that the first air path connecting joint 22 of the static level 2 at the head end is connected to the upper part of the liquid storage tank 1 through the first air path pipe 4, the second air path connecting joint 23 of the static level 2 at the head end is connected to the first air path connecting joint 22 of the middle static level 2 through the third air path pipe 9, the second air path connecting joint 23 of the middle static level 2 is connected to the first air path connecting joint 22 of the static level 2 at the end through another third air path pipe 9, and the second air path connecting joint 23 of the static level 2 at the end is connected to the first air path pipe 4 through the second air path pipe 5; the first water path connecting joint 24 of the static level 2 at the head end is connected to the lower part of the liquid storage tank 1 through the first water path pipe 3, and the static level 2 at the head end is connected to the first air path connecting joint 22 of the middle static level 2 through another third air path pipe 9. The second water channel connection joint 25 of the level 2 is connected to the first water channel connection joint 24 of the middle static level 2 through a second water channel pipe 8, the second water channel connection joint 25 of the middle static level 2 is connected to the first water channel connection joint 24 of the end static level 2 through another second water channel pipe 8, and the second water channel connection joint 25 of the end static level 2 is sealed by a plug; the second circuit connection joint 27 of the first section static level 2 is connected to the first circuit connection joint 26 of the middle static level 2 through a circuit connection line 7, and the second circuit connection joint 27 of the middle static level 2 is connected to the first circuit connection joint 26 of the end static level 2 through another circuit connection line 7.

[0029] like Figure 3-Figure 5As shown, the first water channel connection joint 24 and the second water channel connection joint 25 both include a connecting pipe 251 and a sleeve 252 arranged on the level instrument body 21. The sleeve 252 is sleeved on the outer wall of the connecting pipe 251, and there is a cavity 253 between the two for inserting the water channel pipe. The sleeve 252 is provided with a fastening component for fastening the water channel pipe.

[0030] It can be understood that in order to ensure that the first water channel pipe 3 or the second water channel pipe 8 can be firmly connected to the first water channel connecting joint 24 or the second water channel connecting joint 25 to prevent it from falling off or loosening, thereby causing abnormal data obtained by the static level 2, the first water channel pipe 3 and the second water channel pipe 8 are directly used for explanation below; first, the operator can insert the water channel pipe into the cavity 253. In this embodiment, the outer wall of the water channel pipe is provided with a thread, and the thread of the water channel pipe is matched with the thread of the inner wall of the sleeve 252 to achieve a threaded connection between the water channel pipe and the sleeve 252. After the water channel pipe is connected, the inner wall of the water channel pipe is in contact with the outer wall of the connecting pipe 251, and the outer wall of the water channel pipe is in contact with the inner wall of the connecting pipe 251. Then the operator can operate the fastening assembly, and the fastening assembly will press the outer wall of the water channel pipe to prevent the water channel pipe from loosening.

[0031] Specifically, the fastening assembly includes a locking nut 254 threadedly connected to the outer wall of the sleeve 252, and a plurality of through holes 258 circumferentially opened along the axis of the sleeve 252, a fastening unit provided at each through hole 258, the fastening unit including an extrusion block 255 slidably connected to the locking nut 254, and a fastener provided at the through hole 258, the fastener being extrusion-fitted with the extrusion block 255;

[0032] In which, the extrusion block 255 is wedge-shaped, and the fastener includes an elastic part 256 fixedly connected to the sleeve 252 and having elasticity, and a wedge-shaped fitting part 257 is arranged on the movable end of the elastic part 256, and the fitting part 257 is extruded and matched with the extrusion block 255; the inner wall of the sleeve 252 is provided with an annular groove 259, and the sleeve 252 is slidingly connected to the extrusion block 255 through the annular groove 259.

[0033] It can be understood that after the water pipe is inserted into the cavity 253, the operator can rotate the locking nut 254, and the locking nut 254 moves toward the direction close to the level body 21. The locking nut 254 will drive the extrusion block 255 to move toward the direction close to the level body 21. The extrusion block 255 will squeeze the fitting portion 257, and the elastic portion 256 will be deformed. The bottom side of the fitting portion 257 will contact the outer wall of the water pipe, thereby pressing the outer wall of the water pipe, thereby making the water pipe It is firmly arranged in the cavity 253; when the fastening assembly is no longer needed to lock the water pipe, the operator can reversely rotate the locking nut 254 to move the locking nut 254 away from the level body 21, and the locking nut 254 will drive the extrusion block 255 to move, so that the extrusion block 255 no longer squeezes the fitting part 257. At this time, the elastic part 256 is reset, and the reset of the elastic part 256 will drive the fitting part 257 to reset, so that the fitting part 257 no longer presses the outer wall of the water pipe.

[0034] To sum up, by connecting the static level 2 at each measuring point to the display 6, maintenance personnel can directly see the detailed data of each measuring point on the on-site display 6, so that even in a complex engineering environment, they can quickly obtain necessary information, speed up fault diagnosis and processing, and promptly discover and mark measuring points with abnormal pressure, help avoid possible safety accidents, and improve the safety of manual maintenance. At the same time, the display 6 can also directly display the operating status of the current measuring point, so that the information of the current measuring point can be understood more intuitively, reducing the need for manual point-by-point inspection, especially in environments with limited vision or space. This advantage is particularly obvious; in addition, the setting of the fastening component can make the water pipeline firmly connected to the static level 2.
