[0029] A railway roadbed settlement monitoring device includes a monitoring tube 101, which is a hollow cylindrical structure. The interior of the monitoring tube 101 is used to store liquid. A fixed steel bar 102 is provided at the bottom of the monitoring tube 101. The fixed steel bar 102 is configured to be in a pointed cone shape at one end away from the monitoring tube 101. The monitoring tube 101 is vertically plugged and fixed to the ground by the fixed steel bar 102. A vertical observation window 103 is provided on the side of the monitoring tube 101. The vertical observation window 103 is used to observe the liquid level inside the monitoring tube 101. A first four-way pipe 104 is provided on the lower surface of the monitoring tube 101. The top of the first four-way pipe 104 is connected to the center of the bottom of the monitoring tube 101. A second four-way pipe 105 is provided on the upper surface of the monitoring tube 101. The bottom of the second four-way pipe 105 is connected to the center of the top of the monitoring tube 101. Through connection, the sides of the first four-way pipe 104 and the second four-way pipe 105 are respectively and horizontally penetrated with a delivery pipe 106, the monitoring tube 101 is provided with a plurality of them, and the plurality of monitoring tubes 101 are used in combination, the first four-way pipes 104 arranged below two adjacent monitoring tubes 101 are through-connected through the delivery pipe 106, and the second four-way pipes 105 arranged above two adjacent monitoring tubes 101 are through-connected through the delivery pipe 106, the delivery pipe 106 arranged between the two first four-way pipes 104 is used to transport liquid, and the delivery pipe 106 arranged between the two second four-way pipes 105 is used to transport gas; the monitoring tube 101 is externally sleeved with a liquid level monitoring alarm mechanism 200, and the liquid level monitoring alarm mechanism 200 is used to monitor the liquid level in the monitoring tube 101 and issue an early warning;

[0030] Among them, multiple monitoring tubes 101 mean that the user can select an appropriate number of monitoring tubes 101 according to the length of the railway roadbed that needs to be monitored, and connect them to each other using the conveying pipe 106 to achieve simultaneous monitoring of the settlement of a section of railway roadbed. At the same time, the user can also control the spacing between the monitoring tubes 101 by selecting an appropriate length of the conveying pipe 106, so as to obtain the most accurate railway roadbed settlement monitoring results; and, multiple monitoring tubes 101 can form a communicating vessel after being interconnected by the conveying pipe 106, so the liquid level height of the liquid inside each monitoring tube 101 should be the same.

[0031] The vertical observation window 103 is sealed with transparent glass to prevent the liquid inside the monitoring tube 101 from flowing out through the vertical observation window 103. At the same time, the monitoring tube 101 is also provided with a scale line on one side of the vertical observation window 103 to facilitate the user to read and record the initial liquid level.

[0032] The liquid level monitoring alarm mechanism 200 may be provided with an ultrasonic sensor or a photoelectric sensor or the like which can sense the liquid level inside the monitoring tube 101, and can trigger the liquid level monitoring alarm mechanism 200 to sound an alarm when the liquid level inside the monitoring tube 101 reaches a preset value;

[0033] The first four-way pipes 104 at the bottom of two adjacent monitoring tubes 101 are connected by a delivery pipe 106, so that the liquid inside the two adjacent monitoring tubes 101 can flow through the first four-way pipe 104 and the delivery pipe 106. At the same time, the second four-way pipes 105 at the tops of the two adjacent monitoring tubes 101 are connected by the delivery pipe 106, so that the air above the inside of the two adjacent monitoring tubes 101 can flow through the second four-way pipe 105 and the delivery pipe 106, so as to avoid the situation that the liquid inside the monitoring tubes 101 cannot flow between each other due to the effect of atmospheric pressure. When the upper and lower ends of the adjacent monitoring tubes 101 are connected by the delivery pipe 106, a communicating vessel can be formed between the two, so that the liquid levels inside the two are always kept consistent.

[0034] When in use, the monitoring tubes 101 are evenly fixed vertically on the railway roadbed to be monitored by using a fixing steel bar 102, and the monitoring tubes 101 are adjusted to be at the same height, and then the tops and bottoms of adjacent monitoring tubes 101 are connected to each other by using a conveying pipe 106, and then liquid is introduced into the assembled monitoring tubes 101 through the first four-way pipe 104 at the bottom of the monitoring tube 101 at the edge, so that the liquid level is basically at the middle position of the monitoring tube 101, and then the liquid level monitoring alarm mechanism 200 is used to monitor the liquid level inside each monitoring tube 101. When one of the monitoring tubes 101 in the area is When the roadbed settles, the monitoring tube 101 on it will move downward along with the settled roadbed. Since the height of the monitoring tube 101 is lower than that of the other monitoring tubes 101, the liquid inside the other monitoring tubes 101 will flow into the monitoring tube 101 that moves downward, thereby increasing the liquid level in the monitoring tube 101 that moves downward, while the liquid levels in the other monitoring tubes 101 decrease. In this case, it is only necessary to observe the height of the liquid level in any one of the above-mentioned combined monitoring tubes 101 to know whether there is railway roadbed settlement within the monitoring distance, which greatly improves the monitoring distance and efficiency of railway roadbed settlement monitoring.

[0035] The present invention combines and connects the monitoring tubes 101 by using the conveying pipe 106, so that the user can combine a suitable number of monitoring tubes 101 according to actual needs to monitor the railway subgrade settlement at the same time, thereby performing long-distance segmented real-time monitoring of the railway subgrade settlement, greatly improving the coverage of railway subgrade settlement monitoring, and also improving the monitoring efficiency.

[0036] Furthermore, the liquid level monitoring alarm mechanism 200 has an annular shell 201, a fixing bolt 202 is threadedly installed on one side of the annular shell 201, and the annular shell 201 is fixed to the monitoring tube 101 by the fixing bolt 202. An alarm light 203 is installed on the outer wall of one side of the annular shell 201, and the alarm light 203 is used to emit a light alarm when the liquid level inside the monitoring tube 101 reaches a preset height. A sound alarm 204 is installed on the outer wall of the other side of the annular shell 201, and the sound alarm 204 is used to emit a sound alarm when the liquid level inside the monitoring tube 101 reaches a preset height. The alarm light 203 and the sound alarm 204 are respectively arranged on both sides of the fixing bolt 202; an arc-shaped reed 301 is fixedly installed on the inner wall of one side near the center of the annular shell 201, and an adsorption block 302 is fixedly glued to the movable end of the arc-shaped reed 301; A contact block 303 is fixedly installed, and the contact block 303 is arranged corresponding to the adsorption block 302. The contact block 303 cooperates with the arc-shaped spring piece 301, and the contact block 303 and the arc-shaped spring piece 301 are combined to form a switch structure. The switch structure formed by the contact block 303 and the arc-shaped spring piece 301 is electrically connected to the power supply circuit of the alarm light 203 and the sound alarm 204, and the switch structure formed by the contact block 303 and the arc-shaped spring piece 301 is used to control the working state of the alarm light 203 and the sound alarm 204; a floating block 304 is movably arranged inside the monitoring tube 101, and an annular magnet 305 is fixedly arranged on the upper surface of the floating block 304, and the annular magnet 305 cooperates with the adsorption block 302, and the annular magnet 305 is used to adsorb the adsorption block 302, and the adsorption block 302 is used to push the arc-shaped spring piece 301 toward the contact block 303 when being adsorbed by the annular magnet 305;

[0037] In order to improve the success rate of triggering the alarm when the liquid level inside the monitoring tube 101 reaches a preset value, a method of triggering the alarm by adsorbing the adsorption block 302 by the annular magnet 305 is provided. This method is a purely mechanical triggering method with high working reliability.

[0038] The annular housing 201 has a built-in battery, which can supply power to the alarm light 203 and the sound alarm 204 so that they can sound an alarm.

[0039] During use, the liquid level monitoring alarm mechanism 200 is first fixed to a suitable height outside the monitoring tube 101 by means of the fixing bolts 202. When the liquid level inside the monitoring tube 101 rises or falls, the liquid drives the annular magnet 305 to move upward or downward through the floating block 304. When the annular magnet 305 moves to the middle of the annular shell 201, the adsorption block 302 is attracted by the annular magnet 305 and moves. The movement of the adsorption block 302 pushes the arc-shaped reed 301 toward the contact block 303, thereby connecting the power supply circuits of the alarm light 203 and the sound alarm 204, causing both to sound an alarm at the same time.

[0040] Further, the connection between the first four-way pipe 104 and the delivery pipe 106 and the connection between the second four-way pipe 105 and the delivery pipe 106 are both penetrated and installed with a female quick connector 401, the female quick connector 401 is a normally closed quick connector end, and both ends of the delivery pipe 106 are respectively penetrated and installed with male quick connectors 402, the male quick connectors 402 are normally open quick connector ends, the female quick connector 401 cooperates with the male quick connector 402, and the first four-way pipe 104 and the second four-way pipe 105 are both quickly connected with the delivery pipe 106 through the cooperation relationship between the female quick connector 401 and the male quick connector 402;

[0041] Among them, when the quick connector female end 401 is not inserted into the quick connector male end 402, it can close the pipeline and effectively seal the monitoring tube 101; for the first four-way tube 104 at the bottom of the monitoring tube 101 at the edge and the second four-way tube 105 at the top, there is always an interface that is not connected to the delivery tube 106, so the normally closed quick connector female end 401 is used to effectively seal the interface that is not connected to the delivery tube 106, so that the amount of liquid in the communicating vessel composed of multiple monitoring tubes 101 can remain unchanged, avoiding the situation where the liquid level inside the monitoring tube 101 drops due to liquid evaporation and accidental spillage.

[0042] Furthermore, a pressure relief valve 500 is installed on the top of the second four-way pipe 105. The pressure relief valve 500 is arranged above the monitoring tube 101. The monitoring tube 101 is connected to the external space through the second four-way pipe 105 and the pressure relief valve 500. The pressure relief valve 500 is used to automatically discharge the over-pressure gas inside the monitoring tube 101.

[0043] Among them, since this device is mostly used outdoors, under high temperature conditions in summer, the liquid inside the monitoring tube 101 evaporates due to the high temperature, causing the air pressure inside the monitoring tube 101 to increase. By setting a pressure relief valve 500, the air pressure inside the monitoring tube 101 can be kept within a safe range, avoiding damage to the monitoring tube 101 due to high temperature and high pressure.

[0044] Furthermore, a mounting tube 601 is provided at the connection between the fixed steel bar 102 and the monitoring tube 101, and the mounting tube 601 is used to fix the monitoring tube 101 above the fixed steel bar 102. Slots for the first four-way pipe 104 to pass through are provided on both sides of the mounting tube 601. A bearing plate 602 is provided on the inner wall of the mounting tube 601, and the bearing plate 602 is used to bear the monitoring tube 101.

[0045] Among them, since the first four-way tube 104 is arranged at the bottom of the monitoring tube 101, the monitoring tube 101 cannot be directly installed on the fixed steel chisel 102. Therefore, the installation tube 601 is arranged to better install the monitoring tube 101 on the fixed steel chisel 102 without affecting the normal use of the first four-way tube 104; by arranging a bearing plate 602 inside the installation tube 601, the monitoring tube 101 can be separated, and sufficient placement space is reserved for the first four-way tube 104, thereby preventing the first four-way tube 104 from being squeezed and damaged by the weight of the monitoring tube 101.

[0046] Furthermore, a drainage mechanism 700 is provided between the fixed steel chisel 102 and the mounting tube 601, and the drainage mechanism 700 has a drainage shell 701, and an insertion hole 702 is opened at the center of the top of the drainage shell 701, and the insertion hole 702 is arranged corresponding to the first four-way pipe 104, and one end of the bottom of the first four-way pipe 104 is inserted into the drainage shell 701 through the insertion hole 702, and a push rod 703 is inserted transversely through one side of the drainage shell 701, and the push rod 703 is located at the center of one end inside the drainage shell 701 and is fixedly connected with a guide rod 704, and the diameter of the guide rod 704 is smaller than the diameter of the push rod 703, and the guide rod 704 is arranged to transversely penetrate the drainage shell 701 away from the end of the push rod 703, and the guide rod 704 A baffle 706 is fixedly provided at one end outside the drainage housing 701, and the baffle 706 is used to prevent the guide rod 704 from falling off from the drainage housing 701. A resistance spring 705 is sleeved outside the guide rod 704, and the resistance spring 705 is arranged inside the drainage housing 701. The resistance spring 705 is used to prevent the push rod 703 from pushing in the direction of the guide rod 704. An L-shaped drainage pipe 707 is continuously connected between the push rod 703 and the guide rod 704. One end of the L-shaped drainage pipe 707 is correspondingly arranged with the first four-way pipe 104, and the other end of the L-shaped drainage pipe 707 is connected to the external space through the guide rod 704. The L-shaped drainage pipe 707 is used to discharge the liquid inside the monitoring cylinder 101 through the first four-way pipe 104;

[0047] The first cross-tube 104 is well sealed against the inner wall of the insertion hole 702 and the push rod 703 to prevent the liquid inside the monitoring tube 101 from overflowing through the first cross-tube 104.

[0048] The purpose of setting the drainage mechanism 700 is to drain the liquid inside the monitoring tube 101 when there is a lot of liquid inside, so that the liquid level can be convenient for observation; at the same time, when the device is finished, the liquid inside the monitoring tube 101 can also be quickly drained through the drainage mechanism 700;

[0049] When in use, the monitoring tube 101 is placed inside the installation tube 601, so that the first four-way pipe 104 passes through the insertion hole 702 and enters the drainage housing 701. At this time, the opening at the bottom of the first four-way pipe 104 is blocked by the push rod 703, so that the liquid inside the monitoring tube 101 cannot flow out through the first four-way pipe 104, and the push rod 703 is pushed toward the drainage housing 701, so that the L-shaped drainage pipe 707 is correspondingly connected with the first four-way pipe 104, so that the liquid inside the monitoring tube 101 can enter the L-shaped drainage pipe 707 through the first four-way pipe 104, and be discharged through the guide rod 704. Since pushing the push rod 703 toward the drainage housing 701 will squeeze the resistance spring 705, when the push rod 703 is released, the push rod 703 will be pushed out of the drainage housing 701 again by the resistance spring 705, and due to the obstruction of the baffle 706, the push rod 703 and the guide rod 704 will not fall off from the drainage housing 701.

[0050] In summary, when in use, the monitoring tubes 101 are uniformly fixed vertically on the railway roadbed to be monitored by using the fixing steel bar 102, and the monitoring tubes 101 are adjusted to be at the same height, and then the tops and bottoms of adjacent monitoring tubes 101 are connected to each other by using the conveying pipe 106, and then liquid is introduced into the combined monitoring tubes 101 through the first four-way pipe 104 at the bottom of the monitoring tube 101 at the edge, so that the liquid level is basically at the middle position of the monitoring tube 101, and then the liquid level monitoring alarm mechanism 200 is used to monitor the liquid level inside each monitoring tube 101. When one of the monitoring tubes 101 is at When the roadbed in the area settles, the monitoring tube 101 on it will move downward with the settled roadbed. Since the height of the monitoring tube 101 is lower than that of the other monitoring tubes 101, the liquid inside the other monitoring tubes 101 will flow into the monitoring tube 101 that moves downward, thereby increasing the liquid level in the monitoring tube 101 that moves downward, while the liquid level in the other monitoring tubes 101 decreases. In this case, it is only necessary to observe the height of any one of the liquid levels in the above-mentioned combined monitoring tubes 101 to know whether there is railway roadbed settlement within the monitoring distance, which greatly improves the monitoring distance and efficiency of railway roadbed settlement monitoring.

[0051] The liquid level monitoring alarm mechanism 200 is fixed at a suitable height outside the monitoring tube 101 by means of fixing bolts 202. When the liquid level inside the monitoring tube 101 rises or falls, the liquid drives the annular magnet 305 to move upward or downward through the floating block 304. When the annular magnet 305 moves to the middle of the annular housing 201, the adsorption block 302 is attracted by the annular magnet 305 and moves. The movement of the adsorption block 302 pushes the arc-shaped reed 301 toward the contact block 303, thereby connecting the power supply circuits of the alarm light 203 and the sound alarm 204, so that both of them sound an alarm at the same time.

[0052] The present invention combines and connects the monitoring tubes 101 by using the conveying pipe 106, so that the user can combine a suitable number of monitoring tubes 101 according to actual needs to monitor the railway subgrade settlement at the same time, thereby performing long-distance segmented real-time monitoring of the railway subgrade settlement, greatly improving the coverage of railway subgrade settlement monitoring, and also improving the monitoring efficiency.
