If workers continue construction in areas with potential safety hazards, secondary accidents can easily escalate the injury or death situation. Utility Model Content

[0003] The purpose of this utility model is to provide a safety device for road construction, which can notify workers in adjacent road sections immediately when an accident occurs on the construction section, so as to avoid secondary accidents.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

The longitudinal level mechanism includes a cover A fixedly installed below the longitudinal mounting groove. A semi-circular damping disc A is rotatably installed in the cover A, with the straight surface of the damping disc A facing upwards. There is a frictional force between the damping disc A and the cover A that does not affect the rotation of the damping disc A. A locking bolt A is screwed onto the cover A.

On the end face of A, an electronic level A electrically connected to the controller is also installed on the straight surface of the damping disc A; the transverse level mechanism includes a cover B fixedly installed below the longitudinal mounting groove, in which a semi-circular damping disc B is rotatably installed, with the straight surface of the damping disc B facing upwards, and there is a frictional force between the damping disc B and the cover B that does not affect the rotation of the damping disc B; a locking bolt B is screwed onto the cover B, and after tightening the locking bolt B, the end of the locking bolt B abuts against the end face of the damping plate B; an electronic level B electrically connected to the controller is also installed on the straight surface of the damping disc B.

[0013] Preferably, the directional broadcasting device includes two directional sound generators hinged to both ends of the support plate.

[0023] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model 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 utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] like Figures 1-3 The road construction safety equipment shown includes a support plate 1. A controller 2 is fixedly installed on the ground of the support plate 1 to receive and issue various commands. A set of rechargeable battery modules 3 is installed at the bottom of the support plate. The battery modules are electrically connected to the controller 2 via wires to provide the controller 2 with the necessary power. A set of support brackets 4 is connected to the bottom of the battery modules 3. These support brackets can be inserted into the soil at the construction site to ensure the stability of the system. Simultaneously, a directional broadcasting device 5 is installed on the support plate 1. This directional broadcasting device is electrically connected to the controller to send alarm and evacuation signals to adjacent construction sections under the controller's drive. It should be noted that, in order to accurately determine whether a landslide or collapse has occurred at the construction site, this system also includes a tilt alarm device 6 installed on the support plate. In the event of geological disasters such as landslides or collapses at the construction site, the tilt alarm device 6, inserted into the site via the support brackets 4, will inevitably experience angle changes. If the angle changes from the initial state, and the change is greater than the threshold, the tilt alarm device 6 can send a signal to the controller 2, which is electrically connected to it, thereby driving the controller to activate the directional broadcast device to emit sound.

[0027] It is important to understand that construction sites are generally uneven. To ensure the tilt alarm device can adapt to various uneven surfaces, this design includes a longitudinal mounting groove 11 and a transverse mounting groove 12 on the support plate 1. The longitudinal mounting groove 11 extends along the width of the support plate, while the transverse mounting groove extends along the length of the support plate. Both the longitudinal mounting groove 11 and the transverse mounting groove 12 are designed to penetrate both the top and bottom of the support plate.

[0028] Meanwhile, the tilt alarm device 6 in this solution includes a longitudinal level mechanism 61 and a transverse level mechanism 62. The longitudinal level mechanism 61 includes a housing A611 fixedly installed below the location of the longitudinal mounting slot, and a damping disc A612 is installed within the housing A. It should be noted that, as... Figure 2 As shown, damping disc A is a semi-circular metal disc that is rotatably mounted within housing A, while maintaining a certain level of friction with housing A. It is important to understand that the friction between damping disc A and housing A ensures that when the operator adjusts the rotation angle of damping disc A within housing A, damping disc A will not rotate relative to housing A due to its own weight. Additionally, a locking bolt A613 is screwed onto housing A, with its end abutting against the end face of damping disc A to lock the position of damping disc A after adjustment. Furthermore, as... Figure 3 As shown, an electronic level A614 is also installed on the straight surface of damping disc A. This electronic level is a strip level and is electrically connected to the controller. After the road construction safety equipment is installed on the construction site, workers adjust the rotation angle of damping disc A to ensure that the electronic level on damping disc A is initially in a horizontal state. In the event of an accident, the road construction safety equipment will tilt along with the moving soil from the collapse or landslide. At this time, the angle on electronic level A changes, triggering the electronic level to send an alarm signal to the controller. Controller 2 then controls the directional broadcast device to emit an alarm sound.

[0029] It should be noted that the horizontal leveling mechanism 62 in this solution includes a housing B621 fixedly installed below the location of the horizontal mounting slot, and a damping disc B622 is installed inside the housing B. It should be noted that, as... Figure 2As shown, the damping disc B is a semi-circular metal disc that is rotatably mounted within the housing B, while maintaining a certain level of friction with the housing B. It is important to understand that the friction between the damping disc B and the housing B ensures that when the operator adjusts the rotation angle of the damping disc B within the housing B, the damping disc B will not rotate relative to the housing B due to its own weight. Additionally, a locking bolt B623 is screwed onto the housing B. The end of this locking bolt B abuts against the end face of the damping disc B, locking the damping disc B in its final position after adjustment. Furthermore, as... Figure 3 As shown, an electronic level B624 is also installed on the straight surface of the damping disc B. This electronic level is a strip level and is electrically connected to the controller. After the road construction safety equipment is installed on the construction site, workers adjust the rotation angle of the damping disc B to ensure that the initial state of the electronic level on the damping disc B is horizontal. In the event of an accident, the road construction safety equipment will tilt along with the moving soil from the collapse or landslide. At this time, the angle on the electronic level B changes, triggering the electronic level to send an alarm signal to the controller. The controller then controls the directional broadcast device to emit an alarm sound.

[0030] It should be noted that this solution achieves comprehensive monitoring of geological changes through the setting of longitudinal level instrument mechanism 61 and transverse level instrument mechanism 62, and drives the directional broadcasting device to issue alarms in a timely manner through the controller connected to the above mechanisms, thereby reducing the probability of secondary accidents.

[0031] In addition, such as Figure 1 As shown, the directional broadcasting device 5 in this solution has a folding and storage function. Specifically, the directional broadcasting device 5 includes two directional speakers 51 hinged to both ends of the support plate 1. A connecting plate assembly is provided between the directional speakers 51 and the support plate 1 so that the directional speakers 51 can be kept in an upright state after being folded up. Specifically, in this solution, the connecting plate assembly includes two connecting plates 52, the ends of which are rotatably hinged to the sides of the corresponding directional speakers and the support plate. At the same time, each of the two connecting plates has a sliding groove 521 extending along the length direction, and the two connecting plates are connected by a locking bolt C53. Specifically, the locking bolt 53 is tightened after passing through the overlapping sliding groove of the two connecting plates. It should be noted that when it is necessary to store the directional speakers, the locking bolt C is loosened so that the free ends of the two connecting plates can slide relative to each other.

[0032] In addition, such as Figure 2 , Figure 3 As shown, the support device 4 in this solution includes a telescopic rod 41 connected to the bottom of the battery module 3, and a mounting plate 42 is coaxially connected to the bottom of the telescopic rod 41. Figure 2As shown, the insertion plate has several circumferentially distributed insertion holes 421, and an iron rod 43 is inserted into each insertion hole, which can slide axially. Simultaneously, locking bolts D44 are screwed onto the outer edge of the insertion plate. The end of the locking bolt D passes through the insertion plate 42 and abuts against the surface of the iron rod 43 to fix the iron rod with its adjusted extension length. When the ground where the support device is inserted has significant unevenness, especially if there are gravel in the soil affecting the insertion of individual iron rods, the extension length of individual iron rods can be adjusted to ensure the stability of the support device 4 after it is inserted into the soil.

[0033] As a further improvement to the above-described embodiment, a protective ring 45 is also provided around the bottom of the insertion tray in this solution. It should be noted that the height of this protective ring is greater than the length of the sharp part of the iron rod. Its function is to prevent the iron rod from piercing the device when it needs to be stored, allowing the entire iron rod to be pulled out and its sharp part to be hidden behind the protective ring.

[0034] In addition, a signal transmitting module 7 is installed on the support plate 1 in this solution. This signal transmitting module can communicate with the workers' walkie-talkies at the construction site. Simultaneously, this signal transmitting module is also electrically connected to the controller 2. Therefore, when the controller drives the directional broadcast device to emit an alarm sound, it can also send an alarm signal to the walkie-talkies held by the workers through the signal transmitting module 7, further enhancing the propagation efficiency of the evacuation alarm.

[0035] It should also be noted that a charging base 8 is also installed on the support plate 1. This charging base is electrically connected to the battery module 3 so that the walkie-talkies used by the workers can be charged on site.

[0036] Working Principle: When a landslide or collapse occurs on the construction section, the resulting slippage will cause the device to tilt. At this time, the horizontal level detected by the longitudinal and transverse level mechanisms in the tilt alarm device will change. When the change exceeds a set threshold, a signal is sent to the controller electrically connected to it. Upon receiving the signal, the controller activates the directional broadcast device to emit an alarm sound to adjacent construction sections, thus preventing casualties in the event of a secondary accident. Furthermore, it should be noted that while activating the directional broadcast, the controller also sends a signal to the signal transmitting module, enabling the signal transmitting module to send evacuation commands to the connected walkie-talkie.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
