Description
Technical Field
[0001] This invention belongs to the field of monitoring technology for sunken shaft construction, and in particular relates to a power supply device and method for wireless monitoring equipment that generates electricity synchronously during the construction of sunken shafts. Background Technology
[0002] Traditional sunken shafts are mostly constructed using the caisson method. The caisson method is a process in which prefabricated segments are assembled ring by ring to form a shaft. Then, by excavating soil inside the shaft, the shaft overcomes the frictional resistance between the shaft wall and the soil under its own weight (with external force applied if necessary) and gradually sinks to the design elevation. Then, the bottom is sealed and the internal structure is constructed. It follows a cyclical process of "assembly-sinking-reassembly-sinking". This method is widely used in urban underground engineering, such as the construction of shafts for deep tunnels, shield tunnels, pump stations, and integrated pipe corridors.
[0003] The caisson construction method is constrained by factors such as enclosed working environments, deep water, and limited space, making the caisson prone to tilting, displacement, and segment cracking. Furthermore, in urban environments, the construction area is often surrounded by buildings and pipelines, making it extremely sensitive to soil disturbance. Wireless monitoring equipment, with its core advantages of requiring no wiring, adapting to the humid and dusty environment underground, and providing real-time data transmission, is integrated throughout the entire construction process, covering key monitoring scenarios such as the caisson itself, the assembled structure, and the surrounding environment, providing real-time data support for construction safety and quality control.
[0004] Currently, most commonly used wireless monitoring devices are powered by batteries or solar energy, but both methods have significant shortcomings in practical applications: battery power is limited by its endurance and requires frequent replacement, which not only results in high maintenance costs but also poses significant safety hazards during the replacement process; solar power is affected by weather and sunlight conditions, and its energy stability is difficult to guarantee, especially in deep well operations, rainy seasons, or nighttime conditions, where it cannot function properly at all. Summary of the Invention
[0005] The main objective of this invention is to propose a power supply device and method for wireless monitoring equipment that generates power synchronously during the construction of a sunken vertical shaft, which can effectively solve the problems in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A power supply device for wireless monitoring equipment based on synchronous power generation during the construction of a sunken vertical shaft, comprising:
[0008] The shaft, located inside a vertical shaft, is assembled ring by ring from several prefabricated segments;
[0009] Wireless monitoring equipment is fixed to the ground at the wellhead of the vertical shaft;
[0010] Synchronous power generation equipment, located inside the shaft and floating on the water surface of the vertical shaft, includes...
[0011] Support plate;
[0012] Two floating plates are fixed to the bottom of both sides of the support plate, respectively;
[0013] The cavity tube is fixedly inserted through the middle of the support plate;
[0014] A turbine generator is fixed to the top of the cavity tube and connected to the wireless monitoring device via a power transmission line;
[0015] A pressure pipe has one end connected to the upper part of the cavity pipe and the other end connected to the turbine generator and facing the turbine generator impeller. The side wall of the pressure pipe has a water inlet and a water valve in the water inlet.
[0016] A piston is slidably mounted inside the cavity tube, and the bottom of the piston has a connecting rod that extends out from the bottom of the cavity tube;
[0017] Two connecting ropes, one end of which is connected to the connecting rod, and the other end of which is connected to the precast segments on both sides respectively.
[0018] Preferably, a shaft tunneling machine is installed at the bottom of the well shaft.
[0019] Preferably, the bottom of the two floats is connected to a spring, the spring being V-shaped, with its two ends connected to the two floats respectively, and its middle part connected to the connecting rod.
[0020] Preferably, solar panels are fixed to the top of the two floating plates.
[0021] Preferably, an air supply device is fixed on the support plate, and the air supply device is connected to the side wall of the cavity tube located below the piston through an air supply pipe.
[0022] Preferably, the inner wall of the precast segment connected to the connecting rope is fixed with an openable ring structure.
[0023] A power supply method for wireless monitoring equipment based on synchronous power generation during the construction of a sunken vertical shaft, employing the aforementioned power supply device, includes the following steps:
[0024] S1: Before the construction of the sunken shaft, the synchronous power generation equipment is pre-assembled. The synchronous power generation equipment includes a support plate, two floating plates, a cavity pipe, a turbine generator, a pressure pipeline, a piston, and two connecting ropes. After the pre-assembly is completed, the system is debugged to ensure that it is in good working condition.
[0025] S2: The synchronous generator is put into the shaft. Under the buoyancy of the two floating plates, the synchronous generator floats on the water surface of the shaft. Then the turbine generator and the wireless monitoring equipment are connected through the power transmission line. The two connecting ropes are connected to the precast segments on both sides respectively.
[0026] S3: The upper part of the piston inside the cavity tube serves as the water receiving cavity, and the lower part of the piston serves as the air receiving cavity. During the construction of the sunken vertical shaft, the shaft, which is assembled from several prefabricated segments ring by ring, sinks. This causes the connecting rod and piston to move downwards via the connecting rope. The air in the air receiving cavity is compressed, and the air pressure increases. The water in the vertical shaft then enters the water receiving cavity from the inlet.
[0027] S4: When the wellbore sinks to the end, the connecting rope is disconnected, the water valve is closed, the compressed air in the air chamber releases energy, pushes the piston to move upward, and the water in the water chamber rushes into the turbine generator along the pressure pipe to drive its impeller to generate electricity. The generated electricity is transmitted to the wireless monitoring equipment through the power transmission line.
[0028] S5: After this power generation cycle ends, the upper precast segments continue to be assembled, and the two connecting ropes are reconnected to the corresponding precast segments on both sides. The shaft continues to sink to complete the next power generation cycle.
[0029] This invention provides a power supply device and method for wireless monitoring equipment that generates power synchronously during the construction of a sunken vertical shaft, which has the following beneficial effects.
[0030] This invention enables the conversion of sinking potential energy into air compression energy into water kinetic energy into electrical energy, generating electricity periodically and sustainably. It fully utilizes the potential energy of the sinking shaft, requires no external power source, and has advantages such as being green and environmentally friendly, self-circulating, and having low maintenance costs. It is particularly suitable for vertical shafts, underwater environments, and other enclosed and complex construction environments, significantly improving the reliability and operating efficiency of the monitoring system. It overcomes the problems of insufficient battery life and poor environmental adaptability of traditional batteries and solar energy in vertical shaft construction environments, and has good engineering adaptability and application value.

[0037] Reference Figure 1-2 This invention provides a power supply device for wireless monitoring equipment that generates power synchronously during the construction of a sunken vertical shaft, comprising:
[0038] Shaft 1, located inside vertical shaft 10, is composed of several prefabricated segments assembled ring by ring;
[0039] Wireless monitoring device 2 is fixed on the ground at the wellhead of shaft 10;
[0040] Synchronous power generation device 3, located inside shaft 1, floats on the water surface of vertical shaft 10, the synchronous power generation device 3 includes
[0041] Support plate 31;
[0042] Two floating plates 32 are fixed to the bottom of both sides of the support plate 31, respectively;
[0043] The cavity tube 33 is fixedly inserted through the middle of the support plate 31;
[0044] The turbine generator 34 is fixed to the top of the cavity tube 33 and is connected to the wireless monitoring device 2 via a power transmission line 38;
[0045] The pressure pipe 35 has one end connected to the upper part of the cavity pipe 33 and the other end connected to the turbine generator 34 and facing the impeller of the turbine generator 34. The side wall of the pressure pipe 35 has a water inlet 39 and a water valve in the water inlet 39.
[0046] Piston 36 is slidably installed inside the cavity tube 33. The bottom of piston 36 has a connecting rod 361, which extends out from the bottom of cavity tube 33. A movable sealing ring is fitted on the connecting rod 361.
[0047] Two connecting ropes 37 are connected at one end to the connecting rod 361, and at the other end to the precast segments on both sides respectively.
[0048] This invention also provides a power supply method for wireless monitoring equipment based on synchronous power generation during the construction of a sunken vertical shaft, employing the aforementioned power supply device and including the following steps:
[0049] S1: Before the construction of the sunken shaft 10, the synchronous power generation equipment 3 is pre-assembled. The synchronous power generation equipment 3 includes a support plate 31, two floating plates 32, a cavity pipe 33, a turbine generator 34, a pressure pipeline 35, a piston 36, and two connecting ropes 37. After the pre-assembly is completed, the system is debugged to ensure that the working condition is good.
[0050] S2: The synchronous generator 3 is put into the vertical shaft 10. Under the buoyancy of the two floating plates 32, the synchronous generator 3 floats on the water surface of the vertical shaft 10. Then the turbine generator 34 is connected to the wireless monitoring equipment 2 through the power transmission line 38, and the two connecting ropes 37 are connected to the precast segments on both sides respectively.
[0051] S3: The upper part of the piston 36 inside the cavity tube 33 serves as the water receiving cavity 331, and the lower part of the piston 36 serves as the air receiving cavity 332. During the construction of the sunken vertical shaft 10, the shaft 1, which is assembled from several prefabricated segments ring by ring, sinks. This causes the connecting rod 361 and the piston 36 to move downwards via the connecting rope 37. The air in the air receiving cavity 332 is compressed, and the air pressure increases. The water in the vertical shaft 10 enters the water receiving cavity 331 from the inlet 39, while the float plate 32 can provide a corresponding amount of balancing buoyancy according to the sinking volume.
[0052] S4: When the well shaft 1 finishes sinking, the connecting rope 37 is disconnected, the water valve is closed, the compressed air in the air receiving chamber 332 releases energy, pushing the piston 36 to move upward, and the water in the water receiving chamber 331 rushes into the turbine generator 34 along the pressure pipe 35 to drive its impeller to generate electricity. The generated electricity is transmitted to the wireless monitoring device 2 through the power transmission line 38 to supply power. Of course, an energy storage device (such as a battery) can also be used to store the electricity.
[0053] S5: After this power generation cycle ends, the upper precast segments continue to be assembled, and the two connecting ropes 37 are reconnected to the corresponding precast segments on both sides. The shaft 1 continues to sink to complete the next power generation cycle.
[0054] This invention enables the conversion of sinking potential energy into air compression energy into water kinetic energy into electrical energy, generating electricity periodically and sustainably. It fully utilizes the sinking potential energy of the shaft 1, requires no external power source, and has advantages such as being green and environmentally friendly, self-circulating, and having low maintenance costs. It is particularly suitable for vertical shafts, underwater environments, and other enclosed and complex construction environments, significantly improving the reliability and operating efficiency of the monitoring system. It overcomes the problems of insufficient battery life and poor environmental adaptability of traditional batteries and solar energy in vertical shaft construction environments, and has good engineering adaptability and promotion and application value.
[0055] As a preferred embodiment, a shaft excavator 4 is installed at the bottom of the shaft 1 to efficiently excavate the soil inside the shaft 1, so that the shaft 1 can gradually sink under its own weight.
[0056] In a preferred embodiment, springs 5 are connected to the bottom of the two floats 32. The springs 5 are V-shaped, with their ends connected to the two floats 32 and their middle section connected to the connecting rod 361. When the well shaft 1 sinks, the connecting rope 37 moves the connecting rod 361 and piston 36 downwards, which also stretches the springs 5. When the well shaft 1 finishes sinking, the springs 5, under their elastic force, push the piston 36 upwards, thereby converting the elastic force of the springs 5 into electrical energy, further improving the power generation efficiency.
[0057] As a preferred embodiment, after the pressure pipe 35 is connected to the cavity pipe 33, it is first bent downward and then bent upward to connect to the turbine generator 34, so that the water inlet 39 can be set at a suitable height position, so that the water in the vertical shaft 10 can smoothly enter from the water inlet 39.
[0058] As a preferred embodiment, solar panels 6 are fixed to the top of the two floating plates 32, providing an additional power supply method that can power the wireless monitoring device 2 even when there is sunlight.
[0059] As a preferred embodiment, an air supply device 7 is fixed on the support plate 31. The air supply device 7 is connected to the side wall of the cavity tube 33 located below the piston 36 through the air supply pipe 8. The air supply device 7 can supplement air to the air receiving cavity 332 to prevent insufficient air volume.
[0060] As a preferred embodiment, an openable ring structure 9 is fixed to the inner wall of the precast segment connected to the connecting rope 37. This ring contains an electrically controlled release mechanism, which remains closed under normal conditions to transmit the tension generated by the segment's sinking. When it is necessary to stop sinking and enter the power generation stage, the operator can control the release mechanism within the device via a remote control signal to open the ring and decouple the rope from the device. The openable ring structure is an electrically controlled release ring clutch, a pre-existing product, and its specific structure will not be described in detail here.
[0061] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
