Description

Technical Field

[0001] This utility model relates to the field of roadbed depth detection technology, and in particular to a highway roadbed depth detection component and ground penetrating radar detection equipment. Background Technology

[0002] Ground-penetrating radar (GPR) is an electronic device that efficiently utilizes high-frequency electromagnetic wave technology for underground exploration. Its detection capabilities surpass those of conventional instruments using ordinary electromagnetic waves, such as pipeline detectors, and it is therefore widely used in various fields including archaeology, foundation depth determination, glacier research, groundwater pollution detection, mineral resource exploration, cave exploration, underground pipeline and cable location, and highway foundation inspection.

[0003] Ground penetrating radar (GPR) is typically found in various fields in the form of a trolley. The trolley design facilitates the transport of GPR by personnel, and its flat chassis keeps the radar equipment level with the ground, making it easier to perform ground penetration work. However, since GPR needs to be moved by personnel, it is easy to encounter weeds and garbage when working in the field. Weeds or garbage can easily get caught under the vehicle, and the GPR cannot effectively detect the ground due to the obstruction of debris. At the same time, the presence of debris can also scratch the detection radar, leading to errors in the detection data.

[0004] To address this, we designed a highway subgrade depth detection component and a ground-penetrating radar detection device. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the accuracy of ground-penetrating radar detection data is reduced due to the influence of external environmental factors in the existing technology. Therefore, a highway subgrade depth detection component and ground-penetrating radar detection equipment are proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A highway subgrade depth detection component includes a detection radar body and a push base symmetrically arranged on the side of the detection radar body, and also includes;

[0008] An anti-obstruction assembly, comprising a protective platform mounted on a push base, pressing plates symmetrically mounted on the side walls of the protective platform, an anti-blocking grille mounted on the inner wall of the protective platform, and a telescopic assembly mounted on the push base;

[0009] A pushing component is disposed on both sides of the pushing base.

[0010] Preferably, the telescopic assembly includes a first telescopic rod disposed on the top of the push base and a fixing plate disposed at the bottom of the first telescopic rod.

[0011] Preferably, the fixing plate is provided with a connecting assembly, which includes a support rod disposed between the protective platform and the fixing plate.

[0012] Preferably, the fixing plate is provided with a detection component, which includes a radar detector head mounted on a support rod.

[0013] Preferably, the actuating assembly includes a second telescopic rod and a first push plate disposed at the output end of the second telescopic rod via a damper.

[0014] A ground-penetrating radar detection device includes the aforementioned roadbed depth detection component, and also includes a vehicle body for placing the aforementioned roadbed depth detection component. The vehicle body is equipped with a battery, and push rods are symmetrically arranged at one end of the vehicle body away from the detection radar body. The push rods are equipped with a display screen.

[0015] Preferably, the bottom of the vehicle body is provided with a plurality of omnidirectional wheels.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention, through the setting of a pressing plate and an anti-blocking grille, allows the pressing plate to press down on foreign objects such as weeds in the detection environment when such objects are present. This effectively prevents weeds below the radar detector from affecting the overall detection work. The action of the first telescopic rod can enhance the pressing effect of the pressing plate on the weeds, and the isolation of the anti-blocking grille can prevent weeds from scratching the radar detector. This frees up the detection area of ​​the radar detector and reduces the risk of damage to the radar detector.

[0018] This utility model, through the setting of a first push plate and a second push plate, can effectively push the garbage forward when there is garbage in the path during detection, preventing the garbage from being rolled into the bottom of the vehicle. The second push plate can effectively protect the casters, preventing the garbage from getting rolled into the casters and causing them to get stuck and unable to move. At the same time, the second push plate can orderly slide weeds or garbage from the bottom of the vehicle body during the vehicle's movement, thereby improving the vehicle's passability.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-4 A highway subgrade depth detection component includes a detection radar body 101 and a push base 103. The push base 103 is symmetrically arranged on the side of the detection radar body 101. In addition, the highway subgrade depth detection component also includes an anti-obstruction component and a push component. Specifically, the anti-obstruction component includes a protective platform 204 arranged on the push base 103, a pressing plate 205 symmetrically arranged on the side wall of the protective platform 204, an anti-blocking grille 206 arranged on the inner wall of the protective platform 204, and a telescopic component arranged on the push base 103. The push component is arranged on both sides of the push base 103.

[0026] When the roadbed depth detection component enters the original roadbed, ensure that the detection radar body 101 is installed and fixed to avoid the detection radar body 101 falling off due to bumps during the movement. Since the original roadbed environment may be grass or rocky ground, and the height of the weeds in the grass is uneven, the staff can improve the detection efficiency of the detection radar body 101 by using the anti-obstruction component. This can effectively prevent the weeds from interfering with the detection radar and affecting the staff's judgment of the roadbed depth. Since weeds can easily get into the bottom of the vehicle and get stuck during the movement of the detection radar body 101, the push component can effectively prevent weeds and garbage on both sides of the vehicle body 1 from being rolled into the bottom of the vehicle.

[0027] As a preferred technical solution in this embodiment, the telescopic component includes a first telescopic rod 104 disposed on the top of the push base 103 and a fixing plate 2 disposed at the bottom of the first telescopic rod 104; further, the fixing plate 2 is provided with a connecting component, which includes a support rod 202 disposed between the protective platform 204 and the fixing plate 2.

[0028] When the roadbed depth detection component moves through the grass and reaches the predetermined detection location, the push base 103 is activated to cause the protective platform 204 to descend. The pressing plates 205 fixedly installed on the bottom of both sides of the protective platform 204 can crush the tall weeds. The weeds are flattened under the crushing of the pressing plates 205, and the anti-blocking grid 206 set on the inner wall of the protective platform 204 can prevent the weeds from rebounding. The anti-blocking grid 206 can effectively reduce the irregular shape of the weeds caused by compression from extending into the detection area. Before reaching the predetermined detection location, the push components on both sides can prevent weed debris from affecting the detection work, which can improve the pushing efficiency of the protective platform 204.

[0029] Furthermore, pushing the first telescopic rod 104 at the top of the base 103 allows for the raising and lowering of the protective platform 204. The fixing plate 2 at the bottom of the first telescopic rod 104 connects to the protective platform 204, which in turn is connected to the fixing plate 2 via a support rod 202. Additionally, a signal transmitter 201 is provided on the back side of the fixing plate 2. This signal transmitter 201 is connected to the detection radar body 101 via a connecting hose 207, which improves the efficiency of detection information transmission.

[0030] It should be noted that the detection radar body 101 is an existing device for detecting the depth of the roadbed. Its body is equipped with a basic power supply for driving the push base 103. The push base 103 is a base that accommodates telescopic rod-shaped components in the prior art.

[0031] As a preferred technical solution in this embodiment, the fixed plate 2 is provided with a detection component, which includes a radar detector head 203 set on the support rod 202. In use, after the operator starts the detection radar body 101, the radar detector head 203, which is fixedly installed below the fixed plate 2, will rise and fall with the first telescopic rod 104.

[0032] It should be noted that the radar detector 203 is installed inside the fixed plate 2. The connecting hose 207 provided on the side wall of the fixed plate 2 enables the signal transmitter 201 to be connected to the radar detector 203, thereby transmitting information to the radar body 101. The radar detector 203 is perpendicular to the top of the protective platform 204.

[0033] Furthermore, the pushing component includes a second telescopic rod 304 and a first push plate 302 disposed at the output end of the second telescopic rod 304 via a damper 301, and wear-resistant cones 303 are evenly distributed on the first push plate 302.

[0034] According to the aforementioned propulsion components, the first push plate 302 can pierce and drag the weeds and debris in front of it when the roadbed depth detection component moves forward. The damper 301 on the back side of the first push plate 302 can reduce the counter-thrust force that occurs when the first push plate 302 contacts the weeds and debris based on its own characteristics. At the same time, the wear-resistant cone 303 on the first push plate 302 moves the weeds and debris out of the travel range of the roadbed depth detection component.

[0035] It should be noted that the first push plate 302 is fixed inside the placement box 3 by the second telescopic rod 304. The placement box 3 is a semi-enclosed component made of metal material, which is fixed to both sides of the highway subgrade depth detection component by welding. The wear-resistant cone 303 is made of wear-resistant metal.

[0036] A ground-penetrating radar detection device includes the aforementioned roadbed depth detection component and a vehicle body 1 for placing the aforementioned roadbed depth detection component. The vehicle body 1 is equipped with a battery 102. A push rod 6 is symmetrically provided at one end of the vehicle body 1 away from the detection radar body 101. A display screen 7 is provided on the push rod 6. In order to realize the movement of the vehicle body 1, a number of casters 4 are provided at the bottom of the vehicle body 1. The casters 4 are commonly used moving components in existing vehicle components and are all rotatably set at the bottom of the vehicle body 1 by rivets.

[0037] It should be noted that a second push plate 5 is provided at the bottom of the vehicle body 1 at the position corresponding to the first push plate 302. The second push plate 5 is fixed to the bottom of the vehicle body 1 by welding. Its main purpose is to prevent the vehicle body 1 from coming into contact with weeds and garbage during the journey and causing it to overturn.

[0038] The working principle of this utility model is as follows:

[0039] Workers push vehicle 1 towards the pre-detection point. During the movement, there is a possibility of encountering weeds or garbage. The first push plate 302 can push away the weeds on both sides in front of vehicle 1. While pushing the weeds, the roots of the weeds will rebound due to the leaf veins. The second push plate 5 at the bottom of vehicle 1 can effectively prevent the leaf veins from rebounding and getting caught in the caster wheel 4. The counter-thrust force generated by the first push plate 302 when pushing the weeds can be effectively absorbed by the damper 301, thereby increasing the pushing force of the first push plate 302. When the pre-detection point is reached, the first extension is activated. When the telescopic rod 104 retracts downwards, the protective platform 204 and the pressing plate 205 on the first telescopic rod 104 apply pressure to the weeds below, forcing the weeds to make room for detection. The anti-blocking grid 206 on the inner wall of the protective platform 204 can prevent the weed leaves from rebounding, thereby reducing the error in the detection data of the radar detector 203 and preventing the radar detector 203 from being damaged by the weeds. Then, the radar detector 203 transmits the data to the detection radar body 101 through the transmitter 201 and displays it on the display screen 7 for the staff to observe.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
