Technical Field

[0001] The utility model relates to the field of road detection, in particular to a road condition detection device. Background Art

[0002] With the improvement of production and living standards, the road surface has changed from traditional dirt road to stone slab, block stone, crushed stone and even cement concrete and asphalt concrete pavement to bear the heavy traffic vehicles. Various traffic control facilities are set up. In the process of urban road construction, it is very necessary to detect various indicators of urban roads, and road surface flatness detection is one of the necessary detection items.

[0003] The prior art can refer to the Chinese authorized utility model patent with publication number CN219621553U. The prior art is specifically a new type of road condition detection device, including a U-shaped shell and a handle, the top of the U-shaped shell is movably connected to the handle; a detection box movably connected to the U-shaped shell is provided inside the U-shaped shell; a laser receiver is provided at one end inside the detection box; and a detachable laser level used in conjunction with the laser receiver is provided inside the U-shaped shell. When the prior art detects the flatness of the road surface, the worker only needs to push the device. When the road is uneven, the laser level does not correspond to the receiver, and an alarm is sounded through a buzzer.

[0004] In the actual implementation of the above-mentioned prior art, when the staff holds the handle to push the device, the distance between the detection box and the U-shaped shell often changes due to the different forces applied to the handle by the staff, which causes the laser emitted by the laser level to not align with the laser receiver, making the prior art difficult to operate and prone to false alarms.

[0028] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings, but the protection scope of the utility model is not limited to the following.

[0029] Reference Figure 1-6 As shown, a road condition detection device comprises: a protective shell 1 parallel to the ground; a handle 2 movably mounted on the top of the protective shell 1; two L-shaped blocks 3 relatively fixedly mounted on the two side walls of the protective shell 1, and a first driving wheel 4 is rotatably mounted on the bottom of the L-shaped block 3; a plurality of road surface detection units evenly distributed inside the protective shell 1 along the length direction of the protective shell 1, for detecting the flatness of the road surface, and the plurality of road surface detection units are independent of each other and can slide inside the protective shell 1 along the height direction of the protective shell 1;

[0030] The road surface detection unit includes an excitation member. The inner top of the protective shell 1 is provided with the same number of trigger members as the road surface detection unit. The excitation member and the trigger end of the trigger member are located in the same plane. When the excitation member is offset, the trigger member is triggered. An alarm unit is provided on the protective shell 1. The alarm unit is electrically connected to the trigger member. The alarm unit includes a buzzer. The buzzer is provided on the outer wall of the protective shell 1. The buzzer is electrically connected to the trigger member.

[0031] The road surface detection unit also includes: a floating plate 7 arranged in the protective shell 1 and slidably connected to the protective shell 1; a second running wheel 5 rotatably installed at the bottom of the floating plate 7; a plurality of floating plates 7 are evenly distributed inside the protective shell 1 along the length direction of the protective shell 1; and an excitation member is installed on the top of the floating plate 7.

[0032] The utility model provides a technical solution. When using the device, the device is placed on the ground so that the first driving wheel 4 and the second driving wheel 5 are in contact with the ground. Then the staff holds the handle 2 and applies force to the handle 2 to push the device to move. During the movement, when encountering a pothole, due to different pressures, the floating plate 7 will move to the inside of the protective shell 1 or to the bottom of the protective shell 1, which will eventually cause the excitation member to deviate, lose the signal connection with the trigger member, and trigger the trigger member. The triggered trigger key links the alarm unit to work, and warns the user to inform the user that the road surface is uneven, completing the road surface detection function. Because the handle 2 is connected to the protective shell 1, and the first driving wheel 4 is connected to the protective shell 1 through the L-shaped block 3, the first driving wheel 4 is subjected to the force applied by the user. No matter what changes in the force applied by the user during work, it will not affect the work of the floating plate 7, thereby avoiding the situation of accidental touch, ensuring the stability of the device during work. Compared with the prior art, the scheme is simple to operate and reduces the situation of accidental touch, which is convenient for the staff to use. At the same time, the setting of three floating plates 7 facilitates more detailed detection of the road surface.

[0033] Preferably: the excitation component is specifically a laser level 9, the trigger component is specifically a laser receiver 10, the laser level 9 is installed on the top of the floating plate 7, the laser receiver 10 is installed on the inner top of the protective shell 1, and the signal emitting end of the laser level 9 extends upward to be parallel to the laser receiver 10.

[0034] Specifically, the laser level 9 is set to emit light to the laser receiver 10 in the working state. The laser receiver 10 receives the light, which means that the inside is normal. When the road surface is uneven, the laser level 9 is offset, and the laser receiver 10 cannot receive the light from the laser level 9. At this time, the laser receiver 10 triggers the alarm unit to work and remind the staff.

[0035] Preferably, an isolation plate 13 is fixedly disposed inside the protective shell 1 , and a signal transmitting end of the laser level 9 passes through the isolation plate 13 .

[0036] Specifically, the floating plate 7 is conveniently isolated from the laser receiver 10 by means of the provided partition 13 .

[0037] Preferably: a plurality of protrusions 8 are provided on two opposite inner walls of the protective shell 1, notches 14 which fit into the protrusions 8 are provided on both sides of the floating plate 7 close to the protrusions 8, the protrusions 8 extend into the notches 14, and the floating plate 7 is slidably connected with the protrusions 8; a sliding groove 11 is provided inside the protrusion 8, and both sides of the floating plate 7 are slidably connected with the sliding groove 11 through sliders; a spring 12 is provided at one end inside the sliding groove 11, and the free end of the spring 12 is connected with the sliders on both sides of the floating plate 7.

[0038] Specifically, the notch 14 and the protrusion 8 can be used to limit the floating plate 7 to prevent the floating plate 7 from shifting left or right. The slide groove 11 is provided to facilitate the floating plate 7 to slide up and down. The spring 12 is provided to facilitate the support of the floating plate 7 and also drive the floating plate 7 to automatically reset, so as to facilitate continuous operation.

[0039] Embodiment 2:

[0041] The technical solution provided by this embodiment is as follows: when the laser receiver triggers the buzzer, it will also trigger the warning light 6 to flash. The warning light 6 can mark the displaced floating plate 7, making it convenient for the staff to determine the displaced floating plate 7 according to the warning light 6, and then determine the potholes, making it convenient for the staff to quickly locate the potholes on the road surface, saving inspection time and accelerating work results.

[0042] The above disclosure is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
