Description

Technical Field

[0001] This utility model relates to the field of cable well maintenance technology, and in particular to a cable well climbing device. Background Technology

[0002] In power systems, cable wells are crucial infrastructure for power transmission networks, requiring frequent entry by workers for equipment inspection and line maintenance. However, the environment inside cable wells is complex and presents numerous safety hazards, such as potential cable leaks, water accumulation, and insufficient oxygen, seriously threatening the lives of workers.

[0003] Existing patent CN222863291U discloses a climbing device for cable well operations. This device incorporates an oxygen concentration detector, an air intake assembly, and multiple lights, and utilizes a controller to achieve coordinated control of each component. When the oxygen concentration detector detects that the oxygen concentration in the cable well is too low, the controller can control the air intake assembly to supply oxygen to the well. Simultaneously, the lights provide illumination for the operation, eliminating the need for maintenance personnel to carry additional lighting and oxygen detection equipment. This reduces the risk of climbing through tangled cables and improves the safety and convenience of the operation.

[0004] While the aforementioned patents offer some innovation in oxygen detection and lighting oxygen supply, they still have shortcomings in addressing cable leakage risks, handling water accumulation in wells, and achieving remote intelligent management. For example, they lack effective leakage warning and protection measures, making it impossible to detect accidental electrification of the ladder in a timely manner; they cannot automatically handle water accumulation in the well, and the damp environment may affect operational safety and equipment operation; furthermore, remote transmission and monitoring of operational environment data is difficult, hindering managers from having real-time access to site conditions and timely resource allocation. Therefore, there is an urgent need for a more comprehensive and safer cable well climbing device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a climbing device for cable well operations.

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

[0007] A cable well climbing device includes a ladder body, which comprises a left frame body and a right frame body. Multiple support arms are equidistantly arranged laterally between the left and right frame bodies. Electric field induction sensors are provided on the upper sidewalls of both the left and right frame bodies. A mounting frame is provided on the upper part of the ladder body. A yellow warning light, a red warning light, and a buzzer are provided on the sidewall of the mounting frame. A protective cover is provided on the side of the mounting frame away from the yellow warning light. A reel is hinged inside the protective cover. A wire is wound inside the reel. One end of the wire is connected to the ladder body, and the end of the wire away from the ladder body is connected to a grounding flat iron.

[0008] Through the above technical solutions: by installing electric field induction sensors on the upper side walls of the left and right frame main body of the ladder, the surrounding electric field strength can be monitored in real time. Once an abnormal electric field is detected, the yellow alarm light, red alarm light and buzzer can be activated to issue an early warning. At the same time, the grounding protection circuit composed of grounding flat iron and wire can quickly conduct the current to the ground when the ladder is accidentally energized, effectively reducing the risk of electric shock to the workers and providing leakage warning and protection for cable well operations.

[0009] Preferably, the mounting bracket has a handwheel on its side wall, and the handwheel is coaxially connected to the reel.

[0010] The above technical solution involves a handwheel on the side wall of the mounting frame that is coaxially connected to the reel. Operators can easily control the reel to wind up and unwind the wire by turning the handwheel. Before operation, the grounding flat iron can be easily laid in a suitable position for grounding. After operation, the wire can be quickly retrieved. The operation is simple and efficient, improving the convenience of using the grounding device.

[0011] Preferably, the top of the ladder body is provided with a storage rack, and the top of the storage rack is provided with a storage slot for placing the grounding flat iron.

[0012] Through the above technical solutions, the storage rack and storage slot set on the top of the ladder body provide a dedicated storage space for the grounding flat iron. When the grounding flat iron is not in use, it can be neatly placed in the storage slot, which not only facilitates storage and management, but also avoids damage or loss caused by random placement of the grounding flat iron, and maintains the overall cleanliness and integrity of the device.

[0013] Furthermore, insulating foot sleeves are fitted at both the top and bottom ends of the left and right frame main bodies.

[0014] Through the above technical solutions, the insulating foot sleeves fitted at the upper and lower ends of the left and right frame main body can effectively isolate the ladder from contact with potentially live parts such as the well wall, preventing workers from being electrocuted due to accidental contact with live parts during climbing, further enhancing the insulation performance of the ladder and providing more reliable safety protection for workers.

[0015] Furthermore, humidity sensors are installed on the lower side walls of both the left and right frame main bodies.

[0016] The above technical solution involves installing humidity sensors on the lower side walls of the left and right frame main bodies to monitor the humidity in the cable well in real time. Once the humidity exceeds the set threshold, it indicates that there may be water accumulation or other dampness problems in the well, providing data for subsequent pumping and drainage operations. This helps to detect and deal with potential dampness hazards in the well in a timely manner and ensure the safety of the working environment.

[0017] Preferably, a water pump is provided at the lower part of the left frame body, and a drain pipe is inserted inside the left frame body. The water pump is connected to the bottom end of the drain pipe, and the top end of the drain pipe extends to the outside of the cable well.

[0018] Through the above technical solution: the water pump and drainage pipe at the bottom of the left frame work together. When the humidity sensor detects that the humidity in the well exceeds the standard, the water pump starts and pumps the water in the cable well out through the drainage pipe, automatically completing the water treatment work, avoiding the impact of water accumulation on the safety of workers and the operation of cable equipment, and ensuring a dry and safe working environment in the cable well.

[0019] Furthermore, the electric field sensing detection circuit is electrically connected to the electric field sensing sensor and is used to receive the electric field intensity signal detected by the electric field sensing sensor and convert the signal into an electrical signal for transmission to the control unit.

[0020] Humidity detection circuit: electrically connected to the humidity sensor, used to receive the humidity signal detected by the humidity sensor and convert the signal into an electrical signal to be transmitted to the control unit;

[0021] Control unit: Electrically connected to the electric field induction detection circuit, humidity detection circuit, yellow alarm light, red alarm light, buzzer and water pump respectively. The control unit controls the working status of the yellow alarm light, red alarm light, buzzer and water pump according to the received electric field strength signal and humidity signal.

[0022] Power supply circuit: Used to provide operating power for electric field sensing sensor, humidity sensor, control unit, yellow alarm light, red alarm light, buzzer and water pump.

[0023] The beneficial effects of this utility model are as follows:

[0024] 1. By combining the electric field induction detection circuit with the electric field induction sensor, dangerous electric fields such as cable leakage can be detected in a timely manner. Combined with the control unit to control the yellow alarm light, red alarm light and buzzer, a graded early warning can be achieved. The grounding protection circuit can quickly conduct away the current when the ladder body is accidentally energized. With the protection of the insulated foot covers, the safety of the workers is guaranteed from early warning to protection, and the risk of electric shock is reduced.

[0025] 2. The humidity detection circuit and humidity sensor monitor the humidity inside the cable well in real time. When the humidity exceeds the standard, the control unit automatically starts the water pump to drain the accumulated water through the drain pipe, ensuring a dry and safe working environment inside the well. The rechargeable battery and charging management module in the power circuit provide a continuous and stable power supply to all electrical components, enabling the device to adapt to the complex and ever-changing humid environment of the cable well and ensuring smooth operation.

In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] Example 1, referring to Figures 1 to 4A cable well climbing device includes a ladder body 1, which includes a left frame body 101 and a right frame body 102. Multiple support arms 103 are equidistantly arranged laterally between the left frame body 101 and the right frame body 102. Electric field induction sensors 2 are provided on the upper side walls of the left frame body 101 and the right frame body 102. A mounting frame 13 is provided on the upper part of the ladder body 1. A yellow alarm light 4, a red alarm light 5 and a buzzer 6 are provided on the side wall of the mounting frame 13. A protective cover 8 is provided on the side of the mounting frame 13 away from the yellow alarm light 4. A reel 9 is hinged inside the protective cover 8. A wire 11 is wound inside the reel 9. One end of the wire 11 is connected to the ladder body 1, and the end of the wire 11 away from the ladder body 1 is connected to a grounding flat iron 12.

[0034] Specifically, the mounting bracket 13 has a handwheel 10 on its side wall, which is coaxially connected to the reel 9. The top of the ladder body 1 has a storage rack 14, which has a storage slot for placing the grounding flat iron 12. The upper and lower ends of the left frame body 101 and the right frame body 102 are fitted with insulating foot sleeves 7. The lower side walls of the left frame body 101 and the right frame body 102 are equipped with humidity sensors 3. The lower part of the left frame body 101 has a water pump 15, and a drain pipe 16 is inserted inside the left frame body 101. The water pump 15 is connected to the bottom end of the drain pipe 16, and the top end of the drain pipe 16 extends to the outside of the cable well.

[0035] Electric field sensing detection circuit: electrically connected to electric field sensing sensor 2, used to receive the electric field intensity signal detected by the electric field sensing sensor, and convert the signal into an electrical signal and transmit it to the control unit;

[0036] Humidity detection circuit: electrically connected to humidity sensor 3, used to receive the humidity signal detected by the humidity sensor and convert the signal into an electrical signal to be transmitted to the control unit;

[0037] Control unit: It is electrically connected to the electric field induction detection circuit, humidity detection circuit, yellow alarm light 4, red alarm light 5, buzzer 6 and water pump 15 respectively. The control unit controls the working status of the yellow alarm light, red alarm light, buzzer and water pump according to the received electric field strength signal and humidity signal.

[0038] Power supply circuit: Used to provide operating power for electric field sensing sensor, humidity sensor, control unit, yellow alarm light, red alarm light, buzzer and water pump.

[0039] The working principle of this embodiment:

[0040] Electric Field Induction and Alarm Principle: Electric field induction sensors are installed on the upper side walls of the left and right frame main bodies of the ladder. According to the principle of electric field induction, when a sensor approaches a charged body, the electric field strength between its electrodes changes, causing a change in voltage or capacitance. This change is interpreted as a signal output by the circuitry within the sensor. When the electric field induction sensor detects that the surrounding electric field strength exceeds a set threshold, it indicates a potential danger such as cable leakage. At this time, a yellow alarm light on the side wall of the mounting frame will illuminate, issuing a warning signal. If the electric field strength further increases and reaches a dangerous level, a red alarm light will illuminate, and a buzzer will sound to remind workers to immediately stop work and evacuate.

[0041] Grounding protection principle: The mounting frame has a reel with a wire wound inside. One end of the wire is connected to the main body of the ladder, and the other end is connected to a grounding flat iron. When work is required, the operator can turn the handwheel, which is coaxially connected to the reel, to release the wire and place the grounding flat iron in a suitable position outside the cable well and ground it. In this way, if the main body of the ladder becomes accidentally energized, the current can be conducted to the ground through the wire and the grounding flat iron, preventing electric shock to the operator and providing protection. After the work is completed, the wire can be retracted using the handwheel, and the grounding flat iron can be stored in the storage slot of the storage rack at the top of the ladder.

[0042] Humidity Detection and Drainage Principle: Humidity sensors are installed on the lower side walls of the left and right frame main bodies. These sensors can be resistive or capacitive. The resistivity of a resistive humidity sensor changes with humidity, while the capacitance of a capacitive humidity sensor changes with humidity. When the humidity sensor detects that the humidity inside the cable well exceeds a set value, it indicates that there may be water accumulation or excessive moisture inside the well. At this time, the water pump installed at the lower part of the left frame main body will start. The water pump will pump the accumulated water out of the cable well through the drain pipe and discharge it to the outside of the cable well, ensuring a safe and dry working environment inside the well.

[0043] Insulation protection principle: Insulating foot covers are fitted at both the top and bottom of the left and right frame main bodies. The insulating foot covers can effectively prevent workers from directly contacting the well wall or other live objects during the climbing process, thus playing an insulating protection role and further ensuring the personal safety of workers.

[0044] 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.
