Description

Technical Field

[0001] This utility model relates to the technical field of bridge construction and maintenance equipment, and in particular to a solar-powered remote bridge bearing grouting layer automatic pouring and maintenance device. Background Technology

[0002] The primary curing method for bridge bearing mortar grouting under normal temperature conditions is natural curing. According to existing industry standards, effective curing measures should be implemented promptly after the mortar grouting is completed, with a curing time of no less than 3 days. These measures mainly include water spraying and applying curing agents. However, both water spraying and curing agent application require regular manual operation, which is significantly affected by environmental conditions and human factors. Issues such as confined work areas, locations inaccessible for curing, untimely or non-standard curing, and even omissions in curing are common. Furthermore, existing curing methods are cumbersome and cannot be performed without manual intervention. Especially during bridge construction, the high height and limited space of the bridge bearing area make manual operation difficult and increases the risk of working near edges, leading to inadequate mortar curing, surface loosening, cracking, and fine cracks, which hinders the long-term control and maintenance of project construction quality. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a solar-powered remote bridge bearing grouting layer automatic pouring and curing device, which can simplify the maintenance process of the grouting layer of bridge bearings, reduce the influence of working environment conditions and human subjective factors, and at the same time form a standardized bearing maintenance operation to improve the maintenance effect of the bearing grouting layer.

[0004] The purpose of this utility model is achieved through the following technical solution: an automatic watering and curing device for the grouting layer of a solar-powered remote bridge bearing, comprising a movable water tank placed on the bridge deck, a watering component fixedly installed on the bearing, and a first connecting pipe connecting the movable water tank and the watering component. Each bearing is provided with an independent watering component, and each watering component consists of multiple nozzles fixedly installed on the bearing and a second connecting pipe connecting the nozzles. The first connecting pipe is a flexible hose, and the second connecting pipe can be either a flexible hose or a rigid pipe.

[0005] The mobile water tank is equipped with a top plate, on which a solar power generation module and a waterproof electrical box are installed. The solar power generation module is equipped with a controller, and the waterproof electrical box contains an electric water pump and a battery. The output terminal of the solar power generation module is electrically connected to the waterproof electrical box and charges the battery in the waterproof electrical box. The battery in the waterproof electrical box supplies power to both the electric water pump and the controller. The controller is equipped with a communication module, which enables communication with a mobile terminal. The electric water pump is equipped with a solenoid valve that controls the opening and closing of the electric water pump, and the control signal output terminal of the controller is connected to the control signal input terminal of the solenoid valve.

[0006] The inlet pipe of the electric water pump is placed inside the mobile water tank. Both ends of the first connecting pipe are equipped with quick connectors. One end of the first connecting pipe is connected to the outlet pipe of the electric water pump through the quick connector, and the other end of the first connecting pipe is connected to the second connecting pipe through the quick connector.

[0007] Preferably, the bottom of the mobile water tank is equipped with multiple rollers for movement. It should be noted that the rollers' movement methods, such as track walking or track walking, are not listed here.

[0008] The bearings are installed between the box girder and the piers. The bearings are an important component supporting the box girder. Depending on the width of the bridge, one or more piers can be arranged, and therefore one or more bearings are required accordingly.

[0009] The electric water pump is an electric diaphragm pump. Electric diaphragm pumps are a type of highly efficient pump. The motor drives the diaphragm on the plungers at both ends to reciprocate back and forth through a gearbox. Within the two pump chambers, four one-way ball valves are installed. The movement of the diaphragm causes a change in the volume of the working chamber, forcing the four one-way ball valves to open and close alternately, thereby continuously drawing in and discharging liquid. It should be noted that electric diaphragm pumps do not require priming and have a self-priming capacity of over 7 meters, making them particularly suitable for this application. Because the diaphragm separates the transported medium from the transmission mechanical components, there is absolutely no leakage of the medium. Furthermore, the pump itself has no shaft seal, greatly extending its service life. Depending on the medium, the diaphragm is made of neoprene rubber, fluororubber, nitrile rubber, etc., fully meeting the requirements of different maintenance conditions.

[0010] Preferably, the communication module is a wireless communication module. In this solution, the communication module is simply a communication signal source (a mobile terminal, such as a mobile phone or a display with an operating interface). Common wireless communication modules can be used in this solution. Comparatively, using a communication module to establish a dedicated wireless data transmission method has the following advantages over other methods: 1. Establishing a wired communication method requires laying cables or digging cable trenches, thus requiring a large amount of manpower and resources; while establishing a dedicated wireless data transmission method using a wireless data transmitter does not require laying cables or digging cable trenches, only connecting a wireless data transmitter to each terminal and erecting an antenna at an appropriate height. In comparison, establishing a dedicated wireless data transmission method using a wireless data transmission module saves manpower and resources, resulting in a significant reduction in investment. 2. When connecting remote sites several kilometers to tens of kilometers apart, wired connections require laying long cables or digging extensive cable trenches, a project that can take months. In contrast, using data transmission modules to establish dedicated wireless data transmission only requires setting up antennas at appropriate heights, completing the project in just a few days or weeks. Wireless connections allow for rapid establishment of communication links, significantly shortening the project timeline. 3. After establishing a communication network, users often need to add new equipment. Wired connections require rewiring, which is cumbersome and may damage existing communication lines. However, using wireless data transmission radios to establish dedicated wireless data transmission allows for system expansion simply by connecting new devices to the radio, offering better scalability. Wireless communication modules can be used through self-built local area networks (433MHz and 2.4GHz bands) or by utilizing public network information platforms such as CDPD, GSM, and CDMA (e.g., common 4G / 5G remote controller modules). These methods are existing technologies and will not be listed here.

[0011] The nozzle is a universal plastic-steel nozzle. Universal nozzles are a common component of sprinkler systems, allowing for adjustment at any angle according to the target. Using plastic-steel material for the nozzle effectively extends its service life.

[0012] The top plate is also equipped with a water inlet and a water outlet, both of which are fitted with covers. The water inlet on the top plate is mainly for adding maintenance water; the cover is only opened when water needs to be added, and closed during maintenance to prevent impurities from falling into the water tank. The cover of the water outlet is used to install the inlet pipe of the electric water pump; ensuring a tight seal between the cover and the inlet pipe is sufficient during use.

[0013] Preferably, the bridge deck is provided with a pipe passage for the first connecting pipe to pass through. It should be noted that the pipe passage can be a pre-reserved hole in the box girder, a gap between two box girders, or the first connecting pipe can pass through the side of the box girder depending on the actual situation. Regardless of the working condition, as long as there is a way to connect the mobile water tank and the pouring assembly through the first connecting pipe on the bridge deck, it is acceptable.

[0014] The photovoltaic modules of the solar power generation module are rotatably mounted on the top plate, which is also equipped with a top rod for supporting the photovoltaic modules. Since both the solar power generation module and the mobile water tank are placed on the bridge surface in this solution, they have good lighting conditions and can be adjusted according to the angle of sunlight.

[0015] This solution divides the maintenance equipment into a mobile water tank and a fixed irrigation assembly. The irrigation assembly is pre-installed. During use, the first connecting pipe connects the mobile water tank to the irrigation assembly. Communication with the controller is achieved via a mobile terminal, and power is supplied to the entire mobile hydroelectric system's power components (electric water pump and controller) via a solar power module. After connecting the first connecting pipe, the electric water pump can be started to irrigate and cure the grout layer of the support. Single or multiple supports can be cured simultaneously. Supports located on one side of the box girder can be cured simultaneously by connecting the irrigation assemblies in series; each support can also be cured individually according to the actual curing needs. After curing of the supports on one side of the box girder is completed, the first connecting pipe is removed, and the mobile water tank is moved to the other side of the box girder for connection and installation.

[0016] The beneficial effects of this utility model are as follows: a fixed grouting component is installed on the bridge pier, which is combined with a mobile water tank that moves on the bridge deck. The flexible connection method is adopted, and the mobile water tank is equipped with its own power supply. Remote maintenance operation is carried out through wireless selection, which changes the existing manual maintenance method and avoids the disadvantages of low maintenance efficiency, great influence from working environment conditions and human subjective factors, high operation risk and high manpower consumption in the existing maintenance method. It greatly improves the maintenance effect of the bearing grouting layer and ensures the construction quality of the bearing grouting layer. Attached Figure Description

Detailed Implementation

[0026] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments and accompanying drawings. 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.

[0027] like Figure 5 , Figure 8 As shown, a solar-powered remote bridge bearing grouting layer automatic pouring and maintenance device includes a mobile water tank 2 movably placed on the bridge deck 1, a pouring component 4 fixedly installed on the bearing 3, and a first connecting pipe 5 connecting the mobile water tank 2 and the pouring component 4. Each bearing 3 is provided with an independent pouring component 4. Each pouring component 4 consists of multiple nozzles 41 fixedly installed on the bearing 3 and a second connecting pipe 42 connecting the nozzles 41. The first connecting pipe 5 is a flexible hose.

[0028] like Figures 1-4As shown, the mobile water tank 2 is equipped with a top plate 21, on which a solar power generation module 22 and a waterproof electrical box 23 are installed. The solar power generation module 22 is equipped with a controller 25 (installed on the back of the solar power generation module 22). It should be noted that the controller 25 is an electrical component, and its installation location is not particularly important. In this embodiment, since the mobile water tank 2 requires water filling, the controller 25, installed on the back of the solar power generation module 22, can operate while the water is submerged. The waterproof electrical box 23 houses an electric water pump 24 and a battery. (The waterproof electrical box 23 has holes for the inlet and outlet pipes of the electric water pump 24 to pass through; during use, the inlet and outlet pipes must be sealed to these holes.) (Yes) The moving parts are installed in a relatively sealed waterproof electrical box 23, which further increases the safety performance of the device. The output end of the solar power generation module 22 is electrically connected to the waterproof electrical box 23 and charges the battery of the waterproof electrical box 23. The battery of the waterproof electrical box 23 supplies power to the electric water pump 24 and the controller 25 respectively. The controller 25 is equipped with a communication module, and the controller 25 communicates with the mobile terminal through the communication module. The electric water pump 24 is equipped with a solenoid valve 26 to control the opening and closing of the electric water pump 24. The control signal output end of the controller 25 is connected to the control signal input end of the solenoid valve 26. The controller 25 adopts the STM32F103.T6 processor commonly used in railway control systems.

[0029] The inlet pipe of the electric water pump 24 is placed inside the mobile water tank 2. Both ends of the first connecting pipe 5 are provided with quick connectors. One end of the first connecting pipe 5 is connected to the outlet pipe of the electric water pump 24 through the quick connector, and the other end of the first connecting pipe 5 is connected to the second connecting pipe 42 through the quick connector.

[0030] The bottom of the mobile water tank 2 is equipped with four casters 211 for movement.

[0031] The support 3 is installed between the box girder and the pier 6. In this embodiment, two supports 3 are arranged at one end of the box girder, such as... Figure 6 , Figure 7 , Figure 8 As shown, four grouting components 4 are installed around each support 3. All grouting components 4 are connected in series to the first connecting pipe 5. The series connection of multiple grouting components 4 can be achieved using a T-junction or a cross-junction, which will not be elaborated here. Figure 6 From the frontal view of the bridge, it can be seen that this embodiment simultaneously pours water to cure two bearings 3. Figure 7 This is a side view of the bridge, showing that in this embodiment, there are pouring components 4 before and after the same support 3. Figure 8This is a top-down view of the bridge, showing four grouting components 4 on both the front and rear of the two supports 3 in this embodiment. The electric water pump 24 is an electric diaphragm pump. The communication module is a wireless communication module; in this embodiment, a 4G wireless communication module (DL7300) is used. This module can be equipped with an expansion port, enabling control of multiple terminal devices. The nozzle 401 is a universal plastic-steel nozzle. The top plate 211 is also provided with a water inlet 27 and a water outlet 28. Both the water inlet 27 and the water outlet 28 are equipped with cover plates 29. The bridge deck 1 is provided with a pipe passage 11 for the passage of the first connecting pipe 5. The photovoltaic module of the solar power generation module 22 is rotatably mounted on the top plate 21, and the top plate 21 is also provided with a top rod 210 for supporting the photovoltaic module.

[0032] Before use, each component is set up. Since the maintenance time is relatively long, the irrigation component 4 can be pre-set on the support so that it can be used directly during the next irrigation maintenance. The water supply, transmission and distribution of other water circuits are set up as follows: First, the electric water pump 24 is connected to the mobile water tank 2 through the outlet hole 28 using a φ15 hose and placed on the bottom of the water tank; Second, the outlet pipe of the electric water pump 24 is connected to the mortar layer area of ​​the bridge support through the first connecting pipe 5 (φ15 hose). The two ends of the φ15 hose are connected to the nozzle 41 and the outlet pipe of the electric water pump 24 using quick connectors; At this point, the water circuit is completed.

[0033] The circuit configuration, including command issuance and execution, and power supply (generation, storage, and distribution), is set up as follows: First, the controller 25 is connected to the solenoid valve 26 of the electric water pump 24 via a control line. The controller 25 has a 4G networking module, which sends timed automatic on / off commands to the electric water pump 24 via a mobile client software, thereby achieving timed automatic watering. The power supply for the aforementioned electrical equipment is continuously supplied by the energy storage lithium battery contained in the solar power generation module 22. The energy storage battery contained in the solar power generation module 22 is connected to a voltage regulator module and a voltage stabilizer module. The voltage regulator module mainly provides a stable voltage output for the electrical equipment, and the voltage stabilizer module mainly supports the electric water pump 24 in adjusting and stabilizing the output water pressure. The control circuit is now complete. The solar power generation module 22 is a commercially available product and can be directly assembled and used.

[0034] In use, the mobile water tank 2 is filled with curing water and placed on the beam surface 1 of the completed bridge. The curing pipeline is arranged in the grouting layer area of ​​the support 3. The curing time, frequency, duration and other parameters of the device are set through the mobile phone control software. At the same time, the orientation and angle of the solar panel of the solar power generation module 22 should be set according to the optimal installation angle in the local area. At this point, the solar remote support grouting layer automatic watering and curing device is set up.

It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
