Description

Technical Field

[0001] The utility model relates to the technical field of contact network maintenance equipment, in particular to a contact network foreign matter cleaning system. Background Art

[0002] The contact network is a high-voltage transmission line that is erected in a zigzag shape above the rails in an electrified railway, and is used by the pantograph to draw current. In outdoor environments, foreign objects such as branches and leaves in the air can easily fall onto the contact network, and frequent strong winds can also blow floating foreign objects such as kites, plastic sheets, and plastic bags onto the contact network. When foreign objects fall or are blown onto the contact network, they are likely to hit the pantograph, causing it to break, which will in turn hinder power collection; and if these foreign objects on the contact network cannot be cleaned up in time, after a long period of stay, especially in rain, snow, or dewy weather, it is likely to cause a short circuit on the contact network, which will affect the normal operation of the contact network, making it prone to interruptions and instability. In summary, it is very necessary to clean up foreign objects on the contact network in a timely manner.

[0003] However, in the prior art, after a malfunction caused by foreign matter occurs, the staff usually manually cleans it, or the staff conducts manual inspections and cleans the foreign matter found, but both methods have problems such as untimely cleaning, labor-intensive, low efficiency, and potential safety hazards. Even though some devices that assist in cleaning foreign matter have gradually appeared on the market in recent years, these devices still cannot eliminate manual operation, and cannot solve the problem of untimely cleaning. For example, a Chinese patent with publication number CN219394216U provides a high-altitude foreign matter removal device for a subway contact network, through which the foreign matter on the contact network can be cleaned by a cleaning mechanism, and the purpose of being able to remove foreign matter without the support of multiple people and a single person can complete the operation; however, even if the number of operators is reduced to a single person, the device still cannot eliminate manual operation, so the above-mentioned problems also exist. Utility Model Content

[0004] The purpose of the utility model is to provide a contact network foreign body cleaning system to solve the problems mentioned in the above background technology that when cleaning foreign bodies on the contact network in the prior art, the cleaning is not timely, manpower is wasted, the efficiency is low, and there are safety hazards.

[0005] The utility model is realized by adopting the following technical solutions:

[0006] An OCS foreign object cleaning system includes a compressed air supply mechanism, an air flow injection mechanism, a detection mechanism, and a control mechanism. The compressed air supply mechanism is connected to the air flow injection mechanism, and the compressed air supply mechanism, the air flow injection mechanism, and the detection mechanism are respectively communicatively connected to the control mechanism. The air flow injected by the air flow injection mechanism is directed towards the OCS.

[0007] In the OCS foreign object cleaning system provided by the present utility model, a compressed air supply mechanism is provided to supply compressed air. The compressed air enters the air flow injection mechanism, and the air flow injection mechanism injects the compressed air towards the OCS in the form of an air flow, thereby effectively blowing the foreign objects on the OCS away; therefore, this system can realize the automatic cleaning of the foreign objects on the OCS without manual operation. In addition, a detection mechanism and a control mechanism are also provided. The detection mechanism is used to detect the foreign object situation on the OCS and transmit the detection result to the control mechanism. The control mechanism can automatically control the operation of the air flow injection mechanism and the compressed air supply mechanism according to the detection result; thus, an active defense system that protects the OCS from being affected by foreign objects can be formed. Compared with the passive defense method of cleaning after a failure caused by a foreign object occurs, this system can realize the timely cleaning of the foreign objects on the OCS, and further avoid the occurrence of failures, thereby having higher reliability.

[0008] Further, the compressed air supply mechanism includes an air compressor. The output end of the air compressor is connected to the input end of the air flow injection mechanism. The air flow injection mechanism includes an air delivery pipeline, a plurality of valves installed in the air delivery pipeline, and an air flow injector connected to the output end of the air delivery pipeline.

[0009] Further, the air flow injector is an intelligent air flow injector that can automatically change its direction, and the valves are intelligent valves. Both the intelligent air flow injector and the intelligent valves are communicatively connected to the control mechanism. The control mechanism can automatically adjust the injection direction and the intensity of the injected air flow of the air flow injector according to the detection result transmitted by the detection mechanism, thereby achieving a better foreign object cleaning effect.

[0010] Further, the detection mechanism includes several detection devices. The several detection devices include, but are not limited to, photoelectric sensors, laser sensors, and cameras. The several detection devices are all communicatively connected to the control mechanism. The detection devices can detect the presence or absence of foreign objects on the OCS and obtain the specific positions of the foreign objects, and transmit the detection results to the control mechanism.

[0011] Further, it also includes a safety monitoring mechanism, which includes a safety switch and / or several monitoring devices. The several monitoring devices include, but are not limited to, a pressure sensor, a temperature sensor, and a current sensor. The several monitoring devices are all communicatively connected to the control mechanism. To ensure the safety of the system, a safety monitoring mechanism is set up to monitor the operating states of the system. The monitoring results of the monitoring devices will be transmitted to the control mechanism. When the operating state is abnormal, the control mechanism can trigger the corresponding safety mechanism, thereby preventing failures and accidents.

[0012] Further, the control mechanism includes a control module and a power supply module. The control module is communicatively connected to the compressed air supply mechanism, the air flow injection mechanism, and the detection mechanism respectively.

[0013] Further, the power supply module includes a storage battery and a solar cell. By setting up the solar cell, the utilization of sustainable energy is realized, and the dependence of the system on traditional energy is reduced.

[0014] Further, the air flow injection mechanism adopts high-temperature resistant and corrosion-resistant materials. To adapt to the outdoor working environment, making the air flow injection mechanism adopt high-temperature resistant and corrosion-resistant materials can effectively extend its service life.

[0015] The beneficial effects achieved by the present utility model are as follows:

[0016] A catenary foreign object cleaning system can detect the foreign object situation on the catenary by setting up a compressed air supply mechanism, an air flow injection mechanism, a detection mechanism, and a control mechanism, and can effectively blow off the foreign objects on the catenary by automatically injecting air flow. Thereby, it can significantly reduce the catenary operation interruption and instability caused by the influence of foreign objects on the catenary, thus contributing to ensuring the normal operation of the catenary. Compared with the existing manual-dependent method, this system can automatically detect and clean the foreign objects on the catenary, and thus can discover foreign objects in real time for timely cleaning, and reduces the need for manual intervention, which helps to reduce labor costs and safety hazards, and at the same time can improve the work efficiency and accuracy.

[0020] To clearly illustrate the solution in the present utility model, the following further description is made in conjunction with the accompanying drawings:

[0021] Embodiment 1

[0022] Please refer to Figures 1 to 2 , this embodiment provides a catenary foreign object cleaning system, which includes a compressed air supply mechanism, an air flow injection mechanism, a detection mechanism, a safety monitoring mechanism and a control mechanism. The compressed air supply mechanism is connected to the air flow injection mechanism, and the compressed air supply mechanism, the air flow injection mechanism, the detection mechanism and the safety monitoring mechanism are respectively communicatively connected to the control mechanism.

[0023] Specifically:

[0024] As Figure 1 shown, the compressed air supply mechanism includes an air compressor 4, and the air compressor 4 is installed on the outer side of the bottom of the catenary support 1 through a bracket and a fixing device. The output end of the upper part of the air compressor 4 is connected to the input end of the air flow injection mechanism; the air flow injection mechanism is located above the air compressor 4, and the air flow injected by the air flow injection mechanism is directed towards the catenary. The air flow injection mechanism includes an air delivery pipe 3, a number of valves installed in the air delivery pipe 3, and an air flow injector 2 connected to the output end of the air delivery pipe 3. The air delivery pipe 3 and the air flow injector 2 are installed on the outer side surface of the catenary support 1 through a bracket and a fixing device; the air flow injection mechanism is made of high-temperature resistant and corrosion-resistant materials, the air flow injector 2 is an intelligent air flow injector that can automatically change the direction, and the valves are intelligent valves. Both the intelligent air flow injector and the intelligent valves are communicatively connected to the control mechanism.

[0025] The detection mechanism includes several detection devices (not shown in the figure, all of which are prior arts and will not be separately disclosed), and the several detection devices include but are not limited to photoelectric sensors, laser sensors and cameras. The several detection devices are all communicatively connected to the control mechanism; the several detection devices are respectively installed at appropriate positions according to the working principle, and the specific positions are determined by technicians according to the actual situation, as long as the detection of foreign objects on the catenary can be achieved.

[0026] The safety monitoring mechanism includes a safety switch and / or several monitoring devices (not shown in the figure, not shown in the figure, all of which are prior arts and will not be separately disclosed). The several monitoring devices include but are not limited to pressure sensors, temperature sensors and current sensors. The several monitoring devices are all communicatively connected to the control mechanism; the several monitoring devices are respectively installed at appropriate positions according to the working principle, and the specific positions are determined by technicians according to the actual situation, as long as the monitoring of the system operation state can be achieved. For example, the pressure sensor can be installed on the output end of the air compressor 4. In addition, to further improve safety, explosion-proof equipment or isolation measures can also be added.

[0027] The control mechanism includes a control module and a power supply module. The control mechanism is installed in the electrical box 5 at the lower part of the air compressor 4. The control module is communicatively connected to the compressed air supply mechanism, the air flow injection mechanism, and the detection mechanism respectively. The control module can be a programmable logic controller (PLC) or a single-chip microcomputer, etc. The power supply module includes a storage battery and a solar cell. In the cleaning system provided in this embodiment, there are two groups of solar panels 6. The two groups of solar panels 6 are respectively installed on both sides of the air compressor 4 through brackets. Both groups of solar panels 6 are electrically connected to the storage battery through a charge controller. In this embodiment, a battery management system (BMS) is also used to monitor and manage the charging and discharging process of the storage battery to extend the life of the storage battery and improve the stability of the system.

[0028] As Figure 2 shown, in practical applications, a catenary foreign object cleaning system is provided at each catenary support 1. Since the distance between two catenary supports 1 is usually 50 - 60 meters, the coverage range of each air compressor 4 should be greater than 25 - 30 meters to achieve full coverage. Technicians can select the parameters of the air compressor 4 and the power supply module according to this condition (the specific selection calculation process does not belong to the improvement made by the present utility model over the prior art, so it will not be elaborated).

[0029] The cleaning system provided in this embodiment can automatically detect the foreign object situation on the catenary and automatically clean the foreign objects on the catenary by means of air flow blowing. Specifically: the detection device can automatically detect the presence or absence of foreign objects on the catenary and obtain the specific position of the foreign objects, and transmit the detection results to the control mechanism. The control mechanism can automatically start the operation of the air compressor 4 and adjust the intensity of the compressed air provided by the air compressor 4 according to the detection results. The compressed air enters the air flow injector 2 through the air delivery pipeline 3. The control mechanism automatically adjusts the air flow injection direction and intensity of the air flow injector 2 according to the detection results, so that the air flow can effectively blow away the foreign objects on the catenary. During the operation of the system, the safety monitoring mechanism monitors the operating states of the system. When an abnormality occurs, the control mechanism will trigger corresponding safety mechanisms, such as automatically shutting down the air compressor 4 and the air flow injector 2, sending out alarm signals, etc., thereby preventing failures and accidents. In terms of power supply, the two groups of solar panels 6 can store the generated electric energy in the storage battery for use by the system when needed.

At the same time, the work efficiency and precision can be improved;

[0033] (3) By using a solar panel 6 for power supply, the utilization of sustainable energy is realized, which helps to reduce the dependence on traditional energy, lower environmental pollution and energy consumption, and thus achieve the goal of sustainable development.

[0034] It should be specifically noted that the parts not described in detail or expanded in the above solutions are all prior arts. For example, the specific principle of how the control mechanism controls other mechanisms belongs to the existing computer software technology. Therefore, these parts do not belong to the improvements made by the present utility model over the prior art, nor do they fall within the protection scope of the technical solution of the present utility model. Thus, they will not be elaborated herein.
