Description

Technical Field

[0001] This application relates to the field of detection device technology, and in particular to detection devices. Background Technology

[0002] The trenching technology for cutoff walls refers to the process of creating trenches during the construction of cutoff walls in hydraulic engineering projects. These trenches are then filled with concrete or other materials to form a wall with seepage prevention capabilities. The basic principle is to reduce the impact force around the cutoff wall by reserving space for water flow or using other methods, thereby improving the wall's seepage prevention performance. To address potential problems during construction, monitoring devices are typically needed to monitor changes in the trench depth.

[0003] In related technologies, the process of detecting the depth of grooves in walls typically involves first inserting a detection device into the groove, then having workers visually read the depth value displayed on the device, and finally manually comparing and judging this value with the design-required limit depth. However, this process is cumbersome, inefficient, and affects construction progress. Furthermore, manual reading is prone to visual errors, reducing the accuracy of the measurement results. Summary of the Invention

[0004] Therefore, it is necessary to provide a detection device to address the problems of low detection efficiency and low accuracy of detection results.

[0005] A detection device includes: a detection mechanism having a first end and a second end disposed opposite to each other, the first end being used to insert into a slot in a wall; a positioning mechanism having an adjustment state and a positioning state disposed opposite to each other, wherein when the positioning mechanism is in the adjustment state, the positioning mechanism is slidably disposed on the detection mechanism to change the distance between the positioning mechanism and the first end, and when the positioning mechanism is in the positioning state, the positioning mechanism is fixed on the detection mechanism to fix the distance between the positioning mechanism and the first end, and the positioning mechanism is used to abut against the wall; and a telescopic mechanism disposed on the detection mechanism, the telescopic mechanism including a telescopic end located at the first end, the telescopic end being movable relative to the first end to protrude from the first end, the telescopic mechanism cooperating with the detection mechanism to detect the depth of the slot.

[0006] In one embodiment, the detection device further includes an alarm mechanism disposed on the positioning mechanism. The alarm mechanism is used to detect the distance between the positioning mechanism and the wall. When the positioning mechanism comes into contact with the wall, the alarm mechanism sounds an alarm.

[0007] In one embodiment, the detection mechanism has a first side and a second side disposed opposite to each other; the positioning mechanism includes: a positioning component, which is slidably sleeved on the outside of the detection mechanism, an alarm mechanism disposed on the side of the positioning component near the second side, the positioning component having an adjustment state and a positioning state disposed opposite to each other; and a connecting component, which is disposed on the side of the positioning component near the first side, the connecting component being used to fix the positioning component to the detection mechanism.

[0008] In one embodiment, a first connecting hole is provided on the side of the positioning component near the first side, and the connecting component is slidably inserted into the first connecting hole. The connecting component has a relatively set connecting position and a clearance position. There is a connecting structure between the connecting component and the detection mechanism. When the connecting component is in the connecting position, the connecting structure is used to fix the positioning component on the detection mechanism. When the connecting component is in the clearance position, the positioning component can slide relative to the detection mechanism.

[0009] In one embodiment, a plurality of connecting slots are provided on the first side along a first direction. The connecting component includes: a first connecting unit, which has a connecting position and a clearance position disposed opposite to each other. The first connecting unit includes a connector. When the first connecting unit is in the connecting position, the connector is located in the connecting slot. When the first connecting unit is in the clearance position, the connector is away from the connecting slot. The connector and the connecting slot cooperate to form a connecting structure. A first reset unit is disposed between the connecting slot and the connector. The first reset unit is used to drive the first connecting unit to move from the clearance position to the connecting position.

[0010] In one embodiment, a second connecting hole is provided on the side of the positioning component near the second side, the axis of the second connecting hole being parallel to the first direction. The alarm mechanism includes: an alarm component having a detection end located within the second connecting hole; and a detection component movably disposed within the second connecting hole along its axis, with one end of the detection component near the first end protruding from the second connecting hole. The detection component has a sensing position and an initial position relative to each other. When the detection component is in the sensing position, one end of the detection component is used to abut against the wall, and the other end of the detection component abuts against and is communicatively connected to the detection end. When the detection component is in the initial position, the detection component is away from the detection end.

[0011] In one embodiment, the detection component includes: a second connecting unit having a sensing position and an initial position disposed opposite to each other, the second connecting unit including an abutment member, wherein when the second connecting unit is in the sensing position, the abutment member abuts against and communicates with the detection end, and when the second connecting unit is in the initial position, the abutment member moves away from the detection end; and a second reset unit disposed between the inner walls of the second connecting unit and the second connecting hole, the second reset unit being used to drive the second connecting unit to move from the sensing position to the initial position.

[0012] In one embodiment, the alarm component includes: a sensor, one end of which is a detection end; and an alarm element, which is disposed on the positioning component and is communicatively connected to the other end of the sensor.

[0013] In one embodiment, the telescopic mechanism includes: a third connecting unit slidably disposed on the detection mechanism, the third connecting unit extending along a first direction, the third connecting unit including a telescopic end; and a third reset unit disposed between the third connecting unit and the second end, the third reset unit being used to drive the third connecting unit to move toward the second end.

[0014] In one embodiment, the detection mechanism has a third connection hole extending along a first direction, and a third connection unit is slidably disposed within the third connection hole.

[0015] The aforementioned detection device features a slidable positioning mechanism mounted on the detection mechanism. By adjusting the distance between the positioning mechanism and the first end, the limit depth for slot measurement can be pre-marked. After inserting the detection mechanism into the slot, when the positioning mechanism abuts against the wall, indicating that the slot depth is not less than the limit depth value, the position of the telescopic end is changed. If the telescopic end can move and protrude beyond the first end, it indicates that the slot depth is too large and does not meet the requirements for continued construction. This structure significantly simplifies the slot depth detection process. Workers no longer need to perform tedious numerical readings and manual comparisons; they can directly determine whether the depth meets the requirements simply by using the telescopic mechanism in conjunction with the detection mechanism. This design improves the efficiency of depth detection, reduces the labor intensity of workers, accelerates construction progress, and avoids visual errors caused by manual readings, thereby significantly improving the accuracy and reliability of the detection results.

[0039] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0040] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0041] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0042] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0043] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0044] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0045] See Figures 1 to 4 This application provides a detection device, which includes a detection mechanism 10, a positioning mechanism 20, and a telescopic mechanism 30. The detection mechanism 10 has a first end 11 and a second end 12 disposed opposite to each other. The first end 11 is used to insert into a slot opened in a wall. The positioning mechanism 20 has an adjustment state and a positioning state disposed opposite to each other. When the positioning mechanism 20 is in the adjustment state, it is slidably mounted on the detection mechanism 10 to change the distance between the positioning mechanism 20 and the first end 11. When the positioning mechanism 20 is in the positioning state, it is fixed on the detection mechanism 10 to fix the distance between the positioning mechanism 20 and the first end 11. The positioning mechanism 20 is used to abut against the wall. The telescopic mechanism 30 is disposed on the detection mechanism 10 and includes a telescopic end located at the first end 11. The telescopic end is movable relative to the first end 11 to protrude from the first end 11. The telescopic mechanism 30 cooperates with the detection mechanism 10 to detect the depth of the slot.

[0046] Using the technical solution of this application, the positioning mechanism 20 is slidably mounted on the detection mechanism 10. By changing the interval between the positioning mechanism 20 and the first end 11, the limit depth of the slot measurement can be marked in advance. After the detection mechanism 10 is inserted into the slot, when the positioning mechanism 20 abuts against the wall, it indicates that the depth of the slot is not less than the limit depth value. At this time, the position of the telescopic end is changed. If the telescopic end can move and protrude from the first end 11, it indicates that the slot depth value is too large and does not meet the requirements for continued construction. This structure significantly simplifies the slot depth detection process. Workers no longer need to perform tedious numerical readings and manual comparisons; they can simply use the telescopic mechanism 30 in conjunction with the detection mechanism 10 to intuitively determine whether the depth meets the requirements. This setup improves the efficiency of depth detection, reduces the labor intensity of workers, speeds up construction progress, and avoids visual errors caused by manual readings, thereby significantly improving the accuracy and reliability of the detection results.

[0047] In some embodiments, the detection mechanism 10 is provided with scale lines 17, and the value of the first end 11 is smaller and the value of the second end 12 is larger.

[0048] See Figure 5The detection device also includes an alarm mechanism 40, which is mounted on the positioning mechanism 20. The alarm mechanism 40 is used to detect the distance between the positioning mechanism 20 and the wall. When the positioning mechanism 20 comes into contact with the wall, the alarm mechanism 40 sounds an alarm. This configuration allows the alarm mechanism 40 to promptly remind workers to perform subsequent operations when the positioning mechanism 20 comes into contact with the wall, further improving detection efficiency. Simultaneously, it eliminates the need for workers to constantly observe the position of the positioning mechanism 20 relative to the wall, reducing their workload.

[0049] See Figure 1 , Figure 4 and Figure 5 The detection mechanism 10 has a first side 13 and a second side 14 arranged opposite to each other. The positioning mechanism 20 includes a positioning component 21 and a connecting component 22. The positioning component 21 is slidably sleeved on the outside of the detection mechanism 10, and the alarm mechanism 40 is disposed on the side of the positioning component 21 near the second side 14. The positioning component 21 has an adjustment state and a positioning state arranged opposite to each other. The connecting component 22 is disposed on the side of the positioning component 21 near the first side 13, and is used to fix the positioning component 21 to the detection mechanism 10. With this configuration, the alarm mechanism 40 is disposed on the positioning component 21, and the positioning component 21 can synchronously drive the alarm mechanism 40 to move during movement. This facilitates the alarm mechanism 40 in detecting the position of the positioning component 21, while ensuring the accuracy of the detection position by the alarm mechanism 40, further improving the reliability of the detection device.

[0050] In some embodiments, the positioning component 21 is a housing structure.

[0051] Specifically, the positioning component 21 has a first connecting hole 211 on the side near the first side 13. The connecting component 22 is slidably inserted into the first connecting hole 211. The connecting component 22 has a relatively connected position and a clearance position. There is a connecting structure between the connecting component 22 and the detection mechanism 10. When the connecting component 22 is in the connected position, the connecting structure is used to fix the positioning component 21 to the detection mechanism 10. When the connecting component 22 is in the clearance position, the positioning component 21 can slide relative to the detection mechanism 10. With this configuration, the operator only needs to change the position of the connecting component 22 to complete the fixing and sliding of the positioning component 21, which is convenient for the operator to change the value of the limit depth. The structure is simple and the operation is convenient.

[0052] See Figure 1 and Figure 2 The X direction is the first direction.

[0053] See Figure 4The first side 13 is provided with a plurality of connecting slots 15 along a first direction. The connecting assembly 22 includes a first connecting unit 221 and a first reset unit 222. The first connecting unit 221 has a connecting position and a clearance position arranged opposite to each other. The first connecting unit 221 includes a connector 2211. When the first connecting unit 221 is in the connecting position, the connector 2211 is located within the connecting slot 15. When the first connecting unit 221 is in the clearance position, the connector 2211 is away from the connecting slot 15. The connector 2211 and the connecting slot 15 cooperate to form a connecting structure. The first reset unit 222 is disposed between the connecting slot 15 and the connector 2211. The first reset unit 222 is used to drive the first connecting unit 221 to move from the clearance position to the connecting position. With this configuration, the first connecting unit 221 can be switched between the connecting position and the clearance position by changing its position. Furthermore, the first reset unit 222 ensures that the first connecting unit 221, after being pulled out of the connecting slot 15, can automatically and quickly return and be fixed within the connecting slot 15. This greatly improves the convenience and efficiency of operation, avoiding the tedious manual pushing or adjustment. Moreover, the positioning of the first connecting unit 221 within the connecting slot 15 provides a stable locking state, enhancing the reliability of the detection device. Simultaneously, it effectively prevents the first connecting unit 221 from accidentally moving in a non-operating state, ensuring the stability of the positioning mechanism 20.

[0054] In some embodiments, the cross-sectional area of ​​the connecting groove 15 gradually decreases along the direction approaching the second side 14, and the cross-sectional area of ​​the connector 2211 also gradually decreases along the direction approaching the second side 14. This configuration improves the smoothness of the connector 2211 moving into the connecting groove 15 and avoids jamming.

[0055] In some embodiments, the first connecting unit 221 further includes a first connecting rod 2212 and an operating member 2213. The operating member 2213 is disposed at one end of the first connecting rod 2212, and the connecting member 2211 is located at the other end of the first connecting rod 2212. When the first connecting unit 221 is in the connected position, the operating member 2213 protrudes from the positioning component 21, which makes it easier for the operator to move the first connecting unit 221 to the avoidance position through the operating member 2213.

[0056] In some embodiments, the operating element 2213 is a pull ring, which facilitates the pulling action by the operator.

[0057] In some embodiments, a first limiting member 213 is provided in the first connecting hole 211. The first limiting member 213 has a first through hole. The first connecting rod 2212 passes through the first through hole. One end of the first reset unit 222 abuts against the first limiting member 213, and the other end of the first reset unit 222 abuts against the connecting member 2211.

[0058] See Figure 5 The positioning component 21 has a second connecting hole 212 on the side near the second side 14, and the axis of the second connecting hole 212 is parallel to the first direction. The alarm mechanism 40 includes an alarm component 41 and a detection component 42. The alarm component 41 has a detection end 4111, which is located inside the second connecting hole 212. The detection component 42 is movably disposed inside the second connecting hole 212 along the axis of the second connecting hole 212. The end of the detection component 42 near the first end 11 protrudes from the second connecting hole 212. The detection component 42 has a sensing position and an initial position that are relatively set. When the detection component 42 is in the sensing position, one end of the detection component 42 is used to abut against the wall, and the other end of the detection component 42 abuts against and is communicatively connected to the detection end 4111. When the detection component 42 is in the initial position, the detection component 42 is away from the detection end 4111. After the detection mechanism 10 is inserted into the slot, if the depth of the slot exceeds the limit depth value, the detection component 42 will contact the wall and slide towards the detection end 4111. When the detection component 42 abuts against the detection end 4111, the alarm component 41 activates. At this point, the detection mechanism 10 cannot be further inserted because the positioning component 21 is against the wall, which also indicates that the depth of the slot has reached the limit depth value. With this setup, the alarm mechanism 40 can provide timely feedback on the depth of the slot. Once the limit depth is reached, the alarm is immediately activated, allowing staff to quickly be notified and proceed with subsequent operations. Simultaneously, the alarm mechanism 40 can be linked with the positioning mechanism 20, working together to detect the depth of the slot, further reducing the complexity of depth detection.

[0059] See Figure 5The detection component 42 includes a second connecting unit 421 and a second reset unit 422. The second connecting unit 421 has a sensing position and an initial position arranged opposite to each other. The second connecting unit 421 includes an abutment member 4211. When the second connecting unit 421 is in the sensing position, the abutment member 4211 abuts against and communicates with the detection end 4111. When the second connecting unit 421 is in the initial position, the abutment member 4211 moves away from the detection end 4111. The second reset unit 422 is disposed between the inner walls of the second connecting unit 421 and the second connecting hole 212. The second reset unit 422 is used to drive the second connecting unit 421 to move from the sensing position to the initial position. With this structure, when the second connecting unit 421 abuts against the wall, continuing to insert the detection device into the slot allows the second connecting unit 421 to move from the initial position to the sensing position. This configuration ensures that the alarm component 41 only operates after the detection component 42 abuts against the wall, guaranteeing the reliability of the alarm component 41's operation. Meanwhile, the second reset unit 422 prevents the alarm component 41 from activating due to accidental activation of the detection component 42. Furthermore, the second reset unit 422 ensures that after the second connection unit 421 moves to the sensing position, it can automatically and quickly move back to its initial position, preventing the alarm component 41 from triggering an alarm for an extended period. This greatly improves the convenience and efficiency of operation, avoiding the tedious manual pushing or adjustment.

[0060] In some embodiments, the second connecting unit 421 further includes a second connecting rod 4212 and a contact member 4213. The contact member 4213 is disposed at one end of the second connecting rod 4212, and the abutment member 4211 is located at the other end of the second connecting rod 4212. When the second connecting unit 421 is in the initial position, the contact member 4213 protrudes from the positioning component 21, which facilitates the contact member 4213 to contact the wall.

[0061] In some embodiments, a second limiting member 215 is provided in the second connecting hole 212. The second limiting member 215 has a second through hole. The second connecting rod 4212 passes through the second through hole. One end of the second reset unit 422 abuts against the second limiting member 215, and the other end of the first reset unit 222 abuts against the contact member 4213.

[0062] Specifically, the alarm component 41 includes a sensor 411 and an alarm element 412. One end of the sensor 411 is the detection end 4111. The alarm element 412 is mounted on the positioning component 21 and is communicatively connected to the other end of the sensor 411. This configuration results in a simple structure for the alarm component 41, while also ensuring a sensitive response, further facilitating subsequent operations by staff.

[0063] In some embodiments, the positioning component 21 is provided with a connecting hole 214 on the side near the second side 14. The connecting hole 214 communicates with the second connecting hole 212. The alarm element 412 is disposed in the connecting hole 214 and protrudes from the positioning component 21. One end of the sensor 411 is located in the second connecting hole 212, and the other end of the sensor 411 is connected to the alarm element 412.

[0064] In some embodiments, sensor 411 is a contact sensor.

[0065] See Figure 3 The telescopic mechanism 30 includes a third connecting unit 31 and a third reset unit 32. The third connecting unit 31 is slidably mounted on the detection mechanism 10, extends along a first direction, and includes a telescopic end. The third reset unit 32 is positioned between the third connecting unit 31 and the second end 12, and is used to drive the third connecting unit 31 to move towards the second end 12. With this configuration, when the alarm 412 sounds, the operator pushes the third connecting unit 31 towards the first end 11. If the third connecting unit 31 can continue to be pushed a short distance, it indicates that the depth of the slot is greater than the limit depth value. This configuration facilitates operation by the operator, and its simple structure makes it easy for the operator to process the telescopic mechanism 30. Furthermore, the third reset unit 32 ensures that after the operator pushes the third connecting unit 31, it can automatically and quickly move back to its initial position, avoiding the tedious manual pushing or adjustment.

[0066] See Figure 3 The detection mechanism 10 has a third connecting hole 16 extending along a first direction, and the third connecting unit 31 is slidably disposed within the third connecting hole 16. This arrangement prevents interference between the telescopic mechanism 30 and other structures, protects the telescopic mechanism 30 from damage, and guides the movement of the third connecting unit 31, ensuring smooth movement.

[0067] In some embodiments, the third connecting unit 31 includes a third connecting rod 311, a first fixing member 312, and a second fixing member 313. The first fixing member 312 is disposed at one end of the third connecting rod 311, and the second fixing member 313 is located at the other end of the third connecting rod 311. The first fixing member 312 and the second fixing member 313 are larger than the diameter of the third connecting hole 16. This arrangement can prevent the third connecting unit 31 from falling out of the third connecting hole 16.

[0068] In some embodiments, a guide structure is provided in the third connecting unit 31 and the third connecting hole 16.

[0069] In this application, the detection device also includes a protection mechanism 50, which is sleeved on the first end 11. The protection mechanism 50 can protect the detection mechanism 10 and prevent the first end 11 from being worn by gravel or other debris in the slot.

[0070] In some embodiments, the protective mechanism 50 may be a metal sleeve.

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
