Description

Technical Field

[0001] This utility model relates to the field of alarm technology for construction near existing pipelines; specifically, this utility model relates to an alarm device for construction near existing pipelines. Background Technology

[0002] Currently, the construction of municipal roads and drainage projects inevitably encounters existing pipelines (including water supply, drainage, gas, heating, electricity, communications, and oil transportation), which is one of the key factors affecting project implementation, with widespread and far-reaching impacts. Improper operation of construction machinery (excavators, pile drivers, etc.) or misjudgment of pipeline locations can easily cause pipeline ruptures or breaks, resulting in economic losses of straight pipes and, in severe cases, personal injury or death. The common method for locating pipelines is confirmation with the property owner combined with manual excavation. However, some pipelines require backfilling after being located due to special requirements. If the on-site construction personnel are unaware of this or the markings are unclear, pipeline damage can still occur. Utility Model Content

[0003] In view of this, the present invention provides an alarm device for construction near existing pipelines, thereby solving or at least alleviating the above-mentioned problems existing in the prior art.

[0004] To achieve the aforementioned objective, this utility model provides an alarm device for construction near existing pipelines, comprising a support frame on which two automatic sensors are arranged vertically. One of the two automatic sensors transmits a signal, and the other receives a signal. An alarm is installed on the top of the support frame, which emits an alarm signal when the signals of the two automatic sensors are blocked. An information sign is installed on the top of the support frame, and the information sign has a marking area for indicating the type and burial depth of the existing pipeline.

[0005] Preferably, the alarm is installed on the notice board, and the alarm and the marked area are located on the same side of the notice board.

[0006] Preferably, the bracket includes four telescopic rods and a length-fixing structure disposed between two adjacent rods, two automatic sensors are respectively installed on the two rods located in the middle, and the notification sign is installed on the rod located at the top.

[0007] Preferably, the length fixing structure includes a sleeve and a first set screw. The sleeve is fixedly sleeved on the top end of the bottom rod of two adjacent rods. The first set screw is threaded onto the sleeve and abuts against the surface of the top rod of the two adjacent rods.

[0008] Preferably, the bracket is fitted with a sliding sleeve, and three centrally symmetrically distributed support legs are rotatably connected to the outside of the sliding sleeve. The support legs are rotatably connected to the bottom end of the bracket by a diagonal brace. A second set screw is threaded onto the sliding sleeve, and the inner end of the second set screw abuts against the surface of the bracket.

[0009] Preferably, a connecting plate is rotatably mounted on the top of the support leg, a track plate is slidably sleeved on the outside of the connecting plate, and the track plate is fixedly mounted on the surface of the sliding sleeve. An adjustment knob is threadedly mounted on the top of the track plate, and the bottom end of the adjustment knob is rotatably connected to the top of the connecting plate.

[0010] Preferably, a support plate is fixedly provided at the bottom of the bracket, and a groove for receiving the support leg is provided on the circumferential surface of the support plate. A rod that can penetrate the support plate and be inserted into the ground is provided at the bottom of the track plate.

[0011] Compared with the prior art, the present invention has at least the following beneficial effects: 1. The alarm device for construction near existing pipelines as described in this application has two self-sensing devices. During construction, the two self-sensing devices are roughly aligned to transmit signals to each other. When machinery enters this area, the signal transmission is blocked, and the alarm sounds, reminding the construction team to proceed with caution due to the presence of existing pipelines. This method is simple to operate and can promptly alert on-site construction teams, preventing damage to the pipelines.

[0012] 2. The three legs of the alarm device for construction near existing pipelines in this application can not only be deployed simultaneously, but also adjusted separately, which can ensure that the alarm device is stably supported on the ground, effectively mitigating the defects caused by vibration of construction equipment and wind blowing, so that the device can stably and effectively play its early warning role.

[0013] 3. The alarm device constructed near existing pipelines in this application uses a support plate and a rod. The rod is inserted into the ground to create a gripping force that stabilizes the center of the alarm device. The support plate prevents the soil in the area where the rod is inserted from turning over, thus improving the stability and gripping force. This greatly enhances the overall stability of the alarm device. Attached Figure Description

Detailed Implementation

[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] like Figures 1 to 3 As shown, an alarm device for construction near an existing pipeline in this embodiment includes a bracket 1. Two automatic sensors 2 are arranged vertically on the bracket 1. One of the two automatic sensors 2 sends a signal and the other receives a signal. An alarm 3 is installed on the top of the bracket 1. The alarm 3 emits an alarm signal when the signals of the two automatic sensors 2 are blocked. An information sign 4 is installed on the top of the bracket 1. The information sign 4 has a marking area 5 for marking the type and burial depth of the existing pipeline.

[0018] When construction equipment enters the vicinity of the existing buried pipeline, the signal transmission path between the two automatic sensors 2 is blocked by the construction equipment. At this time, the alarm 3 sounds an alarm signal to remind the construction personnel that there is a pipeline buried underground in the construction area. The marking area 5 on the information sign 4 indicates the type of existing pipeline and the burial depth, so that the construction personnel can control the construction operation according to the condition of the existing pipeline after receiving the alarm signal, so as to avoid damaging the existing pipeline.

[0019] In a relatively specific embodiment, the alarm 3 is mounted on the information sign 4, and the alarm 3 and the marked area are located on the same side of the information sign 4. Using the information sign 4 as the component for mounting the alarm 3 simplifies the structure of the alarm device.

[0020] In a relatively specific embodiment, the bracket 1 includes four telescopic rods 101 and a length-fixing structure disposed between two adjacent rods 101. Two automatic sensors 2 are respectively installed on the two rods 101 located in the middle, and the information sign 4 is installed on the rod 101 located at the top.

[0021] By telescoping between the four pole sections 101, the height of the notice board 4 can be adjusted according to the actual construction site conditions. Specifically, the adjustable height of the four pole sections 101 is 1.9m to 3m.

[0022] The length-fixing structure includes a sleeve 102 and a first set screw 103. The sleeve 102 is fixedly fitted onto the top of the bottom rod 101 of two adjacent rods 101. The first set screw 103 is threaded onto the sleeve 102 and abuts against the surface of the top rod 101 of the two adjacent rods 101. By loosening the first set screw 103, the overall length of the two rods 101 can be adjusted. After the length adjustment is completed, tightening the first set screw 103 will fix the bracket 1 at the adjusted length.

[0023] In a relatively specific embodiment, a sliding sleeve 6 is provided on the outside of the bracket 1. Three centrally symmetrically distributed support legs 7 are rotatably connected to the outside of the sliding sleeve 6. An inclined brace 8 is rotatably connected between the support legs 7 and the bottom end of the bracket 1. A second set screw 9 is threaded on the sliding sleeve 6, and the inner end of the second set screw 9 abuts against the surface of the bracket 1.

[0024] The three support legs 7, together with the diagonal brace 8, provide stable support for the bracket 1, improving its stability and thus enhancing the stability of the alarm device. In use, simply move the sliding sleeve 6 downwards to unfold the support legs 7 and diagonal brace 8. Then, tighten the second set screw 9 so that it abuts against the surface of the bracket 1, securing the support legs 7 and diagonal brace 8 in the unfolded state. To retract the alarm device, loosen the second set screw 9 and then move the sliding sleeve 6 upwards. The support legs 7 and diagonal brace 8 will rotate towards one side of the bracket 1 for storage. The retracted support legs 7 and diagonal brace 8 occupy less space, making them easier to carry.

[0025] In a relatively specific embodiment, a connecting plate 10 is rotatably mounted on the top of the support leg 7, a track plate 11 is slidably sleeved on the outside of the connecting plate 10, and the track plate 11 is fixedly mounted on the surface of the sliding sleeve 6. An adjustment knob 12 is threadedly mounted on the top of the track plate 11, and the bottom end of the adjustment knob 12 is rotatably connected to the top of the connecting plate 10.

[0026] By setting the connecting plate 10 to slide on the track plate 11 and fixing the track plate 11 on the sliding sleeve 6, the adjusting knob 12 fixes the connecting plate 10 on the track plate 11 during the movement of the sliding sleeve 6, so that the sliding sleeve 6 can drive the three connecting plates 10 to move synchronously, thereby controlling the synchronous unfolding and retraction of the three support legs 7.

[0027] When the three outriggers 7 are supported on the ground, the worker can slightly shake the alarm device to identify the outrigger 7 with the weakest ground support. Then, by rotating the adjustment knob 12 corresponding to that outrigger 7, the top of the outrigger 7 moves downward and further extends, ensuring that the outrigger 7 is finally stably supported by the ground. This setup allows for individual height and extension adjustment of the three outriggers 7 after they are simultaneously extended, ultimately ensuring that all three outriggers 7 are stably supported by the ground. This effectively mitigates the problem of poor stability caused by uneven ground, ensuring the alarm device achieves optimal stability.

[0028] Optionally, a support plate 13 is fixedly installed at the bottom of the bracket 1. The circumferential surface of the support plate 13 is provided with a groove 14 for storing the support legs 7. The bottom of the track plate 11 is provided with a plug 15 that can pass through the support plate 13 and be inserted into the ground. When the alarm device is retracted, the three support legs 7 are respectively located in the three grooves 14. The grooves 14 can limit the movement of the support legs 7, preventing the bottom of the support legs 7 from being subjected to external forces during carrying or transportation, which could cause deformation or damage to the support legs 7 and the rotating connection between the top of the support legs 7 and the connecting plate 10, thereby improving the service life of the device.

[0029] The tray 13 has a through hole for the insertion rod 15 to pass through. The surface of the insertion rod 15 is spirally decorated, providing better grip after it is inserted into the ground. When the alarm device is retracted, the sliding sleeve 6 is at its highest position on the bracket 1, at which point the insertion rod 15 is positioned above the tray 13. This arrangement ensures that the insertion rod 15 is within the circumferential range of the tray 13, thus mitigating the risk of damage caused by the bottom of the insertion rod 15 directly impacting other facilities during carrying and transportation.

[0030] Before deploying the outrigger 7, first place the support plate 13 on the ground, and then deploy the outrigger 7. During the deployment of the outrigger 7, the insertion rod 15 will be inserted into the ground through the insertion hole. As the insertion rod 15 is inserted into the ground, its position is within the lower surface area of ​​the support plate 13. At this time, the support plate 13 is pressed firmly against the ground, preventing the soil where the insertion rod 15 is inserted from turning over, allowing the soil to hold the insertion rod 15 tightly. Therefore, after the alarm device is installed, the gripping force of the insertion rod 15 on the ground provides a stable holding force at the center of the alarm device, greatly improving the stability of the alarm device.

[0031] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
