Description

Technical Field

[0001] The present invention belongs to the technical field of construction, and particularly relates to a mobile monitoring and warning device applied to a construction site. Background Art

[0002] Although the existing monitoring and warning devices at construction sites can collect and record the environmental information of the construction site in real time, such as temperature, humidity, noise and air quality, and capture dust and image records during the construction process through a variety of sensors and cameras, providing monitoring of the construction situation and progress for the construction team. However, most of these devices are fixedly installed, with a small working range, single function, limited monitoring scope, and a large number of device deployments are required to achieve a complete monitoring and warning function. Especially for foundation pit monitoring, the existing methods either rely on manual regular inspections or require additional sensor devices to detect the changes in the slopes of the foundation pit area. This not only consumes a large amount of manpower and equipment investment, but also the installation, disassembly and maintenance of the devices are very difficult. In addition, the existing monitoring devices are difficult to cover the construction progress and personnel monitoring of the entire construction site, and lack an alarm function for abnormal situations such as the overall personnel and construction maintenance of the construction site.

Detailed implementation manners

[0037] Embodiment 1:

[0038] This device adopts a track 1 type of mobile structure, and a mobile device 3 that can move on the track 1 is deployed on the track 1. The track 1 can adopt a single track and is completely deployed within the construction range that needs to be monitored. The track 1 is placed in the air and can be supported above the construction range through a support rod. A power device 32 is provided on the mobile structure itself, and the power device 32 can be controlled to start remotely. Through the power device 32, the overall mobile device 3 can move arbitrarily on the track 1. The start of the power device 32 depends on the power supply, and the mobile device 3 is not always in use. For example, it can be used regularly. When its power is exhausted or in an idle state, it can be controlled to enter the storage box 2 at the end of the track 1 for power supply.

[0039] Such as Figure 1 and Figure 2As shown, the storage box 2 is also provided with a maintenance seat 21. The maintenance seat 21 is used as the door of the box in daily status and is buckled into the side of the box. When maintenance is needed, the maintenance personnel climb up the side of the storage box 2 through the ladder 22 provided under the maintenance seat 21, and then open the maintenance seat 21. The maintenance seat 21 is in a horizontal state, so that the maintenance personnel can lean on or sit on the maintenance seat 21, or some maintenance tools can be placed on the maintenance seat 21.

[0040] In addition, the interior of the storage box 2 is also provided with a power storage component 26, as well as a solar power supply component 23 and a wind power supply component 24 connected to the power storage component 26, wherein the solar power supply component 23 and the wind power supply component 24 are both located above the storage box 2, and are used to convert solar energy and wind energy into electrical energy, and transport it to the power storage component 26 for storage through components such as an inverter, and is used to replenish and supply electrical energy in the mobile device 3 when the power in the mobile device 3 is exhausted. The power supply method adopts contact power supply, and relies on corresponding metal contact points arranged on the mobile device 3 and the power storage component 26 to achieve contact power supply.

[0041] The alarm device 25 is set on the storage box 2. The alarm device 25 has an unlimited transmission function and a built-in Internet of Things module. It can transmit abnormal situation data to the terminal device of the manager through remote transmission for prompting. The same alarm device 25 can also have a local alarm function. For example, the alarm device 25 is equipped with an audible and visual alarm to remind and alarm people around.

[0042] Example 2:

[0043] Based on Example 1, the mobile device 3 includes the power device 32 and the mobile frame 31 mentioned above, wherein the mobile frame 31 serves as a carrier, the power device 32 is arranged on the mobile frame 31, and a plurality of mobile wheels 33 are arranged in the mobile frame 31. All the mobile wheels 33 are clamped on the side wall of the track 1. At least one mobile wheel 33 is transmission-connected to the power device 32, so that the mobile wheel 33 can rotate on the track 1 to achieve the effect of moving the mobile device 3 on the track 1. In addition, a rotary encoder 5 is also connected to the mobile wheel 33. The rotary encoder 5 is used to obtain the data of the rotation of the mobile wheel 33. The ratio is obtained by obtaining the number of rotations of the mobile wheel 33, thereby knowing how far the entire mobile device 3 has moved and what position it is in.

[0044] It should be noted that if the moving range of the overall mobile device 3 is relatively far, the Beidou GPS positioning device can be used to replace the rotary encoder 5. Therefore, the device realizes the moving function to any position on the track 1 through the power device and the moving wheels 33. Then, without the actual maintenance personnel visiting, it can quickly view the construction site at a relatively far position, and there is no need to arrange a large number of sensors and cameras.

[0045] In addition, a base 34 is provided at the lower half of the mobile device 3. A sliding frame 35 is provided at the bottom end of the base 34. A data acquisition device 7 is provided below the sliding frame 35 (not directly connected to the sliding, but rotationally connected to the lower part of the sliding frame 35 through a reversing wheel 37). The data acquisition device 7 integrates a camera, a lighting device, and a total station device. The base 34 is fixedly arranged, and the sliding frame 35 can slide on the base 34, so that the data acquisition device 7 can move to both sides of the track 1 and can obtain construction data of the target area in different directions.

[0046] Embodiment 3:

[0047] As Figure 5 shown, the steering of the data acquisition device 7 depends on the rotation of the reversing wheel 37. The number of reversing wheels 37 is two. At least one reversing wheel 37 is connected to a motor. The motor can drive the reversing wheel 37 to rotate. After the reversing wheel 37 rotates, it synchronously drives the data acquisition device 7 fixed on the reversing wheel 37 to rotate synchronously. Under the action of the mutual contact and limitation between the reversing wheel 37 and the limiting strip 36, the data acquisition device 7 can move to both sides of the track 1 instead of being located below the track 1 (being located below the track 1 will overlap with the dust removal water mist spraying range disclosed later, and the water mist spraying area will affect data acquisition), so as to monitor the construction site on one side or the other side of the track 1.

[0048] It should be noted that the acquisition targets of the mobile acquisition device include, but are not limited to, the face data of personnel in the target area, the construction range size of the use area, the construction status, the maintenance status, and the edge monitoring of the foundation pit slope.

[0049] Embodiment 4:

[0050] The device also integrates a dust removal function, which is realized by dropping water mist from high altitude. Specifically, a dust removal component 4 is also provided in the storage box 2 of the device, including a water tank 41. A water pump is built in the water tank 41. A water supply pipe 42 is connected to the water tank 41. The main part of the water supply pipe 42 is located below the track 1. Thus, by means of the setting of the track 1, it can simply cover the construction area in a large area through the setting of the water supply pipe 42, and realize the ability to dust the entire construction area.

[0051] In order to further achieve the water-saving function and make the spraying position of the water supply pipe 42 controllable, a large number of dust removal nozzles 6 (including nozzles 63) connected to the water supply pipe 42 are also provided below the water supply pipe 42. Each dust removal nozzle 6 is provided with a sliding switch 61 for independently controlling the start and stop of the nozzle. (Sliding up and down enables construction workers to turn on the control nozzles at designated positions for areas that need dust removal).

[0052] Due to the large number of the above nozzles, it is rather cumbersome to batch-control the start and stop of the nozzles, and the degree of automation is low. Therefore, the device further sets a steering wheel 62 and a permanent magnet block 64 on the dust removal nozzle 6, and further sets a side plate 341, a driving strip 342, an electromagnetic device 343 and a cross beam 344 on the base 34.

[0053] Specifically, as Figure 5 shown, the steering wheel 62 is horizontally arranged, and the permanent magnet block 64 is fixedly installed at the bottom end of the dust removal nozzle 6. In the specific implementation process, the mobile device 3 moves above the track 1 to monitor the surrounding construction environment. At the same time, when the direction of the dust removal nozzle 6 needs to be adjusted.

[0054] As Figure 8 shown, by controlling the start of the electromagnetic device 343, the two side plates 341 and the two cross beams 344 are pushed to move horizontally by means of magnetic force. At the same time, the driving strip 342 (which can be a rack) on the side plate 341 will approach or move away from the steering wheel 62 (as Figure 6 shown), and contact the steering wheel 62. Along with the movement of the mobile device 3, the steering wheel 62 is caused to rotate, so that the spraying direction of the dust removal nozzle 6 is sprayed from one side to the other opposite side. If it is necessary to batch-start or stop the nozzles, the magnetic force control device 8 can be controlled to start, and the current direction in the magnetic force control device 8 is used to generate suction or repulsion force on the permanent magnet block 64 below the dust removal nozzle 6, so as to control the passing dust removal nozzles 6, and make the dust removal nozzles 6 realize the switching of the corresponding on or off states through the sliding switch 61.

[0055] It should be noted that, in order to further accurately control the actual control of the mobile device 3 over the passing dust removal nozzles 6, for example, accurately controlling the start and / or turning of the nozzles in the distance range of 50-100 meters from the starting point, this function can be achieved through the rotary encoder 5 in combination with the Beidou GPS positioning device, so that when the mobile device 3 moves to the target area, the magnetic force control device 8 and / or the electromagnetic device 343 are started to control the turning and switching functions of the dust removal nozzle 6.

[0056] The device should also establish a database locally or in the cloud, which is used to store the data historically obtained by the data acquisition device 7, such as the face data of the registered personnel entered, or the data of slope construction and maintenance. In case of any discrepancy between the data obtained during the construction process and the construction data or personnel stored in the database, an alarm will be triggered.

[0057] Specifically, for the function of slope monitoring, the mobile device 3 is used to compare the data of the foundation pit edge. Taking the foundation pit edge as the reference, an alarm will be triggered when displacement occurs on the foundation pit slope.
