Description

Technical Field

[0001] This utility model relates to the field of bridge plate component monitoring technology, specifically a monitoring device for the relative displacement of hollow slab bridge plates. Background Technology

[0002] The monitoring device for relative displacement of hollow slab bridge components is an intelligent device specifically designed for real-time or periodic detection of the relative displacement between precast slab components in hollow slab bridges. Its core function is to ensure the safety of the bridge structure, assess its health status, and prevent potential defects.

[0003] In the existing technology, most of the monitoring devices for the relative displacement of hollow slab bridge components are directly installed on the bridge without a protective structure. This means that the power supply device on the monitoring device is susceptible to external environmental factors, which can cause the installation of the power supply device to gradually detach due to corrosion from the external environment.

[0004] A monitoring device for the relative displacement of hollow slab bridge components is proposed to address the aforementioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a monitoring device for the relative displacement of hollow slab bridge components, in order to solve the problem mentioned in the background art that most of the existing monitoring devices for the relative displacement of hollow slab bridge components are directly installed on the bridge without a protective structure. This causes the power supply device on the monitoring device to be affected by external environmental factors, which can lead to the power supply device falling off due to gradual corrosion from the external environment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a monitoring device for the relative displacement of hollow slab bridge components, comprising a bridge component body and a monitoring device installed on the bridge component body;

[0007] A power supply device is installed on the bridge component body, and a solar panel is installed on one side of the power supply device. The power supply device and the monitoring device are electrically connected by a power supply line.

[0008] Also includes:

[0009] The bridge component is equipped with a protective assembly, which includes a mounting plate. The power supply device and the solar panel are both fixed on the top of the mounting plate. The top of the mounting plate is symmetrically fixed with limit plates, and there are four limit plates.

[0010] Among them, the top of the mounting plate is symmetrically fixed with mounting cylinders, and springs are fixedly installed inside the mounting cylinders, and the top of the springs is fixedly connected with fixing blocks;

[0011] The top of the fixing block is fixedly connected to a fixing rod, and the fixing rods are fixedly connected to a connecting plate.

[0012] Preferably, lifting rollers are symmetrically fixed to the bottom of the connecting plate, and a clamping plate is fixedly connected to the bottom of the connecting plate.

[0013] Preferably, a protective shell is slidably connected to the top side of the mounting plate, and a compression roller is rotatably connected to the top of the protective shell.

[0014] Preferably, the top of the protective shell is provided with a slot, and the two sides of the protective shell are symmetrically provided with fitting slots.

[0015] Preferably, the sizes of the adapter slots on both sides are different.

[0016] Preferably, the mounting plate is provided with a fixing component, the fixing component includes a threaded groove, and the threaded groove is opened inside the mounting plate. Multiple threaded grooves are symmetrically opened, and a threaded block is threadedly connected inside the threaded groove, and a control block is fixedly connected to the top of the threaded block.

[0017] Preferably, the bridge body has a threaded groove inside that is adapted to the threaded block.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the monitoring device for the relative displacement of the hollow slab bridge components facilitates external protection of the power supply device, thereby extending the service life of the power supply device. The specific details are as follows:

[0019] 1. Slide the protective shell to the right, ensuring it is positioned between the limiting plates. The pressing roller on the protective shell will then abut against the lifting roller. Continue pushing the protective shell to force the pressing roller to press against the lifting roller, lifting it and disengaging it from the pressing roller. Simultaneously, the spring returns, resetting the fixing rod and connecting plate, causing the locking plate to rest against the top of the protective shell. Continue pushing the protective shell until the locking plate and slot align, locking the plate into the slot and limiting the protective shell for protection. When maintenance of the power supply device is required, simply pull the connecting plate upwards to disengage the locking plate from the protective shell, facilitating maintenance.

[0020] 2. When the protective shell needs to be installed, the mounting plate can be pressed onto the bridge body, and then the control blocks around the perimeter can be turned to make the control blocks drive the threaded blocks to rotate into the interior of the mounting plate, until the threaded blocks are further into the interior of the bridge body, thereby realizing the installation of the mounting plate.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 The present invention provides the following technical solution:

[0029] A monitoring device for the relative displacement of hollow slab bridge components includes a bridge component body 1 and a monitoring device 2 installed on the bridge component body 1. The monitoring device 2 monitors the bridge component, and the monitoring device 2 is existing technology. A power supply device 201 is installed on the bridge component body 1, and a solar panel 202 is installed on one side of the power supply device 201. A power supply line 203 is electrically connected between the power supply device 201 and the monitoring device 2. A protective component 3 is installed on the bridge component body 1. The protective component 3 includes a mounting plate 301. The power supply device 201 and the solar panel 202 are both fixed on the top of the mounting plate 301. Limiting plates 302 are symmetrically fixed on the top of the mounting plate 301, and there are four limiting plates 302. A mounting cylinder 303 is symmetrically fixed on the top of the mounting plate 301. A spring 304 is fixedly installed inside the mounting cylinder 303, and a fixing block 305 is fixedly connected to the top of the spring 304.

[0030] Among them, a fixing rod 306 is fixedly connected to the top of the fixing block 305, and a connecting plate 307 is fixedly connected between the fixing rods 306, such as Figures 1-5 As shown, when it is necessary to protect the power supply device 201 and the solar panel 202, the protective shell 310 can be slid to the right. When the protective shell 310 is slid, it must be located between the limiting pieces 302. Then, the pressing roller 311 on the protective shell 310 will abut against the lifting roller 308 and match the fitting groove 313, so that the protective shell 310 will directly slide over the power supply device 201 and the solar panel 202 and cover their exterior. At this time, the protective shell 310 is pushed further, so that the pressing roller 311 presses the lifting roller 308 and lifts the lifting roller 308.

[0031] Then, the lifting roller 308 will drive the connecting plate 307 to rise, and the connecting plate 307 will drive the clamping plate 309 to rise. At the same time, the spring 304 is stretched. At this time, the lifting roller 308 will disengage from the pressing roller 311, and the spring 304 will rebound, thereby driving the fixing rod 306 and the connecting plate 307 to reset, so that the clamping plate 309 is pressed against the top of the protective shell 310. At this time, the spring 304 has not rebounded to its maximum length. At this time, the protective shell 310 will continue to be pushed until the clamping plate 309 in the slot 312 corresponds. Then the spring 304 will continue to rebound, so that the clamping plate 309 is locked into the inside of the slot 312, thereby limiting the protective shell 310 and providing protection. When the power supply device 201 needs to be repaired, simply pull the connecting plate 307 upward to make the clamping plate 309 disengage from the inside of the protective shell 310, and then slide the protective shell 310 to the left to disengage the protective shell 310, thereby facilitating the repair of the power supply device 201.

[0032] The bottom of the connecting plate 307 is symmetrically fixed with lifting rollers 308, and the bottom of the connecting plate 307 is fixedly connected with a clamping plate 309. The top side of the mounting plate 301 is slidably connected with a protective shell 310. Furthermore, the protective shell 310 is made of transparent material at the position corresponding to the solar panel 202, so as not to affect the operation of the solar panel 202. The top of the protective shell 310 is rotatably connected with a pressing roller 311. The top of the protective shell 310 is provided with a clamping groove 312, and the two sides of the protective shell 310 are symmetrically provided with adapter grooves 313, the size of the adapter grooves 313 on the two sides being different.

[0033] The mounting plate 301 is provided with a fixing component 4, which includes a threaded groove 401. The threaded groove 401 is formed inside the mounting plate 301, and multiple threaded grooves 401 are symmetrically formed. A threaded block 402 is threadedly connected inside the threaded groove 401. Figure 4As shown, when the protective shell 310 needs to be installed, the mounting plate 301 can be pressed onto the bridge body 1, and then the control blocks 403 around the perimeter can be turned, so that the control blocks 403 drive the threaded block 402 to rotate into the mounting plate 301, until the threaded block 402 enters the bridge body 1, thereby realizing the installation of the mounting plate 301. The top of the threaded block 402 is fixedly connected to the control block 403, and the interior of the bridge body 1 is provided with a threaded groove that matches the threaded block 402.

[0034] Working principle: Before using the device for monitoring the relative displacement of hollow slab bridge components, it is necessary to check the overall condition of the device to ensure it can function normally. Figure 1 - Figure 5 As shown, firstly, when it is necessary to protect the power supply device 201 and the solar panel 202, the protective shell 310 can be slid to the right. When the protective shell 310 is slid, it must be positioned between the limiting pieces 302. Then, the pressing roller 311 on the protective shell 310 will abut against the lifting roller 308 and match the fitting groove 313, so that the protective shell 310 will directly slide over the power supply device 201 and the solar panel 202 and cover them. This can prevent changes in the weather from affecting the use of the power supply device 201. At this time, the protective shell 310 is pushed further, so that the pressing roller 311 presses the lifting roller 308 and lifts the lifting roller 308.

[0035] Then, the lifting roller 308 will drive the connecting plate 307 to rise, and the connecting plate 307 will drive the clamping plate 309 to rise. At the same time, the spring 304 is stretched. At this time, the lifting roller 308 will disengage from the pressing roller 311, and the spring 304 will rebound, thereby driving the fixing rod 306 and the connecting plate 307 to reset, so that the clamping plate 309 is pressed against the top of the protective shell 310. At this time, the spring 304 has not rebounded to its maximum length. At this time, the protective shell 310 will continue to be pushed until the clamping plate 309 in the slot 312 corresponds. Then the spring 304 will continue to rebound, so that the clamping plate 309 is locked into the inside of the slot 312, thereby limiting the protective shell 310 and providing protection. When the power supply device 201 needs to be repaired, simply pull the connecting plate 307 upward to make the clamping plate 309 disengage from the inside of the protective shell 310, and then slide the protective shell 310 to the left to disengage the protective shell 310, thereby facilitating the repair of the power supply device 201.

[0036] When the protective shell 310 needs to be installed, the mounting plate 301 can be pressed onto the bridge body 1, and then the control blocks 403 around the perimeter can be turned to make the control blocks 403 drive the threaded blocks 402 to rotate into the mounting plate 301 until the threaded blocks 402 enter the bridge body 1, thereby realizing the installation of the mounting plate 301.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
