Description

Technical Field

[0001] The utility model relates to the technical field of slope detection, in particular to a portable monitoring and warning device for trench slope collapse. Background Art

[0002] During the construction of municipal pipeline rain and sewage pipe networks, it is usually necessary to excavate trenches. During the trench excavation construction process, displacement is inevitable. Therefore, it is necessary to monitor the trench slope for a long time. Now, there are generally two methods for trench slope detection. One is the monitoring by full-time personnel. This method requires continuous operation. Sometimes, the monitoring information fails to be fed back in time, which may lead to casualties of construction workers due to trench collapse. The other is to set up a monitoring and warning device at the slope to monitor the slope stability in real time and feed back the monitoring information in time.

[0003] The existing monitoring and warning devices still have the following deficiencies in design or use;

[0004] The installation process of the existing monitoring devices is relatively complex. Since the trench operation requires frequent installation and removal as the construction position changes, the complex installation procedure will seriously affect the construction efficiency.

[0005] The existing devices can only monitor trenches within a fixed width range, and are more restricted by the slope angle. The practical range is relatively narrow and has certain limitations.

[0006] Most of the signals of the existing devices are transmitted through mechanical transfer. Although the feedback information is more timely than manual monitoring, sometimes it is easily affected by external factors, resulting in failure to alarm or false alarm.

[0007] Therefore, it is urgent to design a monitoring and warning device for trench slopes to solve the above problems. Summary of the Utility Model

[0008] In view of the deficiencies in the prior art, the utility model provides a portable monitoring and warning device for trench slope collapse. To achieve the above purpose, the utility model adopts the following technical solutions:

[0009] A portable monitoring and warning device for trench slope collapse includes a laser emitter, a laser receiver, an alarm, a hose, a rigid sleeve and a plurality of fixing cones. The laser emitter and the laser receiver are respectively fixed at both ends of the slope. The alarm is connected to the laser emitter and the laser receiver through wires. The hose is arranged between the laser emitter and the laser receiver along the laser direction. A plurality of rigid sleeves are arranged and slidably connected to the hose. The rigid sleeves are arranged at intervals. The fixing cones are clamped on the rigid sleeves and fixed on the slope, so that the laser can be received by the laser receiver through the hose.

[0010] Further, it further includes a fixed ruler, the fixed ruler is provided with spaced grooves, and the rigid sleeve is located in the grooves.

[0011] Further, a handrail is fixedly connected to the fixed ruler.

[0012] Further, a flat plate is fixedly connected to the bottom end of the rigid sleeve, and the flat plate is placed on the slope.

[0013] Further, slots are formed on both sides of the flat plate, and the fixed cone passes through the slots and is inserted into the slope body.

[0014] Further, the fixed cone includes an elastic arc-shaped clamping member and two insertion rods, the clamping member is buckled on the rigid sleeve, and the insertion rods are respectively fixed at both ends of the clamping member.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. The monitoring device contains fewer components. During the installation of the device, only the light source transmitter-receiver and the hose need to be inserted into the slope body to complete the installation of the device, and the operation is simple;

[0017] 2. Only need to align the light source transmitter with the receiver to the hose hole, so the slope angle can be ignored and it can be inserted into the slope body at any angle. At the same time, due to the characteristics of the laser, the distance between the light source transmitter and the receiver can be greatly enlarged, thereby increasing the width of the monitored slope body;

[0018] 3. This device transmits signals through the light source. Compared with other types of devices, the optical signal transmission speed is fast and the anti-interference ability is high. Since the signal transmission process of this device is less, the probability of alarm failure is smaller. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following further describes the technical solutions in the present utility model in conjunction with the drawings and embodiments.

[0024] Please refer to Figure 1 and Figure 2 As shown, a portable monitoring and early warning device for trench slope collapse includes a laser transmitter 2, a laser receiver 3, an alarm 4, a hose 5, a rigid sleeve 6 and several fixing cones 7. The laser transmitter 2 and the laser receiver 3 are respectively fixed at both ends of the slope. The alarm 4 is connected to the laser transmitter 2 and the laser receiver 3 through wires. The hose 5 is arranged between the laser transmitter 2 and the laser receiver 3 along the laser direction. Several rigid sleeves 6 are provided and slidably connected to the hose 5. The rigid sleeves 6 are arranged at intervals. The fixing cones 7 are clamped on the rigid sleeves 6 and fixed on the slope 1, so that the laser can be received by the laser receiver 3 through the hose 5.

[0025] The core principle of this device is that a laser light source is emitted by the laser emission source on the laser transmitter 2 and received by the laser receiver 3. At this time, the alarm 4 is in a normal state. When the slope 1 is displaced, the hose 5 fixed on the slope 1 is driven to a certain extent, and the laser light source in the hose 5 is blocked by the hose 5, and the laser receiver 3 cannot receive the laser signal. At this time, the alarm 4 starts to alarm.

[0026] To ensure the normal operation of the above principle, it is necessary to refer to Figure 1 and Figure 2 for installing the monitoring device. The key to installing this device is to ensure that the hose 5 remains straight during the installation process of the hose 5. The hose 5 is connected and wrapped by the rigid sleeve 6 to ensure that when the hose 5 is fixed on the slope 1, it will not sink randomly due to its own weight and change the straight state of the hose 5. A 2 cm gap is left between each rigid sleeve 6 to ensure that when the slope 1 is displaced and drives the hose 5, the hose 5 can move normally.

[0027] When installing the device, first fix the hose 5 on the slope 1. There are not many requirements for fixing the hose 5, just ensure that the hose 5 remains straight and stable on the slope 1. After the hose 5 is fixed, install the laser transmitter 2 and the laser receiver 3, just ensure that the laser light source enters from one end of the hose 5 and comes out from the other end, and then is received by the light source receiving point on the laser receiver 3.

[0028] In this embodiment, please refer to Figure 1 and Figure 2 As shown, it further includes a fixed ruler 8. The fixed ruler 8 is provided with spaced grooves. The rigid sleeve 6 is located in the grooves. Using the fixed ruler 8 as a reference, ensure that the rigid sleeves 6 are arranged straight, so as to ensure that the hose 5 is straight when fixing the hose 5, and simplify the operation.

[0029] In this embodiment, please refer to Figure 1 and Figure 2As shown, a handrail 9 is fixedly connected to the fixed ruler 8. This facilitates the operator to draw out the fixed ruler 8 from under the rigid sleeve 6, making the operation convenient.

[0030] In this embodiment, please refer to Figure 2 As shown, a flat plate 10 is fixedly connected to the bottom end of the rigid sleeve 6, and the flat plate 10 is placed on the slope. Laying the rigid sleeve 6 with the flat plate 10 on the leveled slope facilitates ensuring that the hose 5 is straight.

[0031] In this embodiment, please refer to Figure 2 As shown, grooves 11 are formed on both sides of the flat plate 10, and the fixing cone 7 passes through the grooves 11 and is inserted into the slope body 1. Using the grooves 11 to position the fixing cone 7 facilitates quickly fixing the hose 5.

[0032] In this embodiment, please refer to Figure 2 As shown, the fixing cone 7 includes an elastic arc-shaped clamping member 12 and two insertion rods 13. The clamping member 12 is buckled on the rigid sleeve 6, and the insertion rods 13 are respectively fixed at both ends of the clamping member 12. The fixing cone 7 can be made of steel sheet material or plastic material, which facilitates fixing the rigid sleeve 6 and is convenient to use.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
