Description

Technical Field

[0001] This utility model relates to a mobile monitoring device for solid waste storage facilities. Background Technology

[0002] Solid waste incineration power generation is a relatively common method of thermal power generation.

[0003] After the solid waste is transported to the power plant, it is stored in a solid waste storage facility. Due to the large amount of waste that needs to be burned, the storage facility is also quite large. Monitoring is required during the storage period to prevent the solid waste from catching fire and to prevent unauthorized personnel from stealing the solid waste.

[0004] The existing monitoring methods mainly consist of a combination of human supervision and video surveillance. Due to the large amount of solid waste burned and the rapid consumption of solid waste, the amount of solid waste accumulated is also large. Therefore, the size of solid waste storage facilities is usually large, and the capture area of ​​each camera is limited, making it difficult to achieve effective coverage.

[0005] Based on the above problems, we designed a mobile monitoring device for solid waste storage that can perform mobile shooting, further reducing blind spots, on the basis of existing fixed shooting. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a mobile monitoring device for solid waste storage that can perform mobile shooting and further reduce blind spots in shooting.

[0007] To solve the above problems, the present invention adopts the following technical solution:

[0008] A mobile monitoring device for a solid waste storage facility includes a monitoring component and a driving component. The monitoring component is displaced by the driving component. Two sets of the monitoring component are provided, located at opposite ends of the driving component. Under the drive of the driving component, the two sets of the monitoring component move in opposite directions.

[0009] Preferably, the drive assembly includes two wheel seats, which are respectively fixed at both ends of the interior of the solid waste storage area. A rope wheel is rotatably mounted on the wheel seat, and a drive rope is installed between the two rope wheels. A drive motor is installed on the top of one of the wheel seats, and the drive motor drives the rope wheel on one side to rotate. The monitoring assembly is driven to move through the drive rope.

[0010] Preferably, the monitoring component includes a guide rod structure, a sliding frame that slides along the guide rod structure, and an elastic frame fixed to the guide rod structure. A battery and a wireless camera are mounted on the sliding frame, and the battery powers the wireless camera. A receiver is also fixed on the sliding frame, and a transmitter is fixed on the elastic frame. When the receiver contacts the transmitter, the battery begins to charge. The sliding frame is fixed to the drive rope.

[0011] Preferably, the guide rod structure includes a guide rod and fixed seats installed at both ends of the guide rod, and the sliding frame and the elastic frame are both installed through the guide rod.

[0012] Preferably, the sliding frame includes an upper clamping plate, a lower clamping plate, and a support plate. Bolts are installed between the upper clamping plate and the support plate and the lower clamping plate. Clips are provided on the opposite surfaces of the upper clamping plate and the lower clamping plate. The drive rope is clamped through the clips at the upper and lower ends. When the bolts are tightened, the clips are fixed to the drive rope. The upper clamping plate, the lower clamping plate, and the support plate cooperate to form a guide hole. The guide rod passes through the guide hole. A mounting plate is welded to the top of the support plate. The wireless camera, the battery, and the receiver are all mounted through the mounting plate.

[0013] Preferably, the elastic frame includes a sleeve and a sliding tube. One end of the sleeve is machined into a limiting plate, the diameter of which is larger than the outer diameter of the sleeve. A guide rod passes through the sleeve, and a screw is screwed into the outside of the limiting plate. The position of the sleeve is locked after the screw abuts against the guide rod. A guide groove is machined on the outer wall of the sleeve, extending away from the limiting plate. The sliding tube is sleeved on the outside of the sleeve and slides along the axial direction of the sleeve. A guide strip that matches the guide groove is machined on the outer wall of the sliding tube. A limiting screw is screwed into the end of the guide groove, limiting the sliding movement of the sliding tube. A spring is sleeved on the sleeve, acting between the limiting plate and the sliding tube. A first mounting plate is installed on the outer wall of the sliding tube. The transmitting end is fixedly installed through the first mounting plate. When the receiving end contacts the transmitting end, the battery begins to charge.

[0014] The beneficial effects of this utility model are:

[0015] This device consists of two monitoring components: one for capturing the left side of the screen and the other for capturing the right side. The drive component is located directly above the central passage of the solid waste storage facility. The drive component drives the two monitoring components to move synchronously from one end of the solid waste storage facility to the other, enabling mobile monitoring and reducing blind spots. Combined with existing fixed camera positions, it can achieve comprehensive and effective monitoring of the solid waste storage facility, allowing for timely detection in the event of a fire.

[0016] This device uses a wireless camera, whose images can be wirelessly transmitted to the central control room. It also uses wireless charging, using a battery to power the wireless camera, eliminating the need for complex wiring and reducing installation costs.

[0017] This device has a simple structure and low cost, making it suitable for widespread use. Attached Figure Description

[0023] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0024] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0025] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Furthermore, in the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "socket," "connect," "through," and "plug-in" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] See Figure 1 The mobile monitoring device for solid waste storage shown includes a monitoring component 1 and a driving component 2. The monitoring component 1 is displaced by the driving component 2. Two sets of the monitoring component 1 are provided, located at opposite ends of the driving component 2. Under the drive of the driving component 2, the two sets of the monitoring component 1 are displaced in opposite directions.

[0029] In the above technical solution, the device is installed in the middle of the solid waste storage area. One set of monitoring components 1 monitors the left side, and another set of monitoring components monitors the right side, thus achieving dual-sided monitoring.

[0030] A single drive component 2 can simultaneously drive the monitoring components 1 on both sides to move from one end of the solid waste storage to the other, achieving comprehensive monitoring.

[0031] The displacement length of drive component 2 can be adjusted according to the size of the solid waste storage area.

[0032] See Figure 2As shown, the drive assembly 2 includes two wheel seats 21, which are fixed at both ends of the solid waste storage area. A rope wheel 22 is rotatably mounted on the wheel seat 21, and a drive rope 23 is installed between the two rope wheels 22. The drive rope 23 is in a tensioned state and has sufficient friction with the rope wheel 22. A drive motor 24 is mounted on the top of one of the wheel seats 21, and the drive motor 24 drives the rope wheel 22 on one side to rotate. The monitoring assembly 1 is driven to move through the drive rope 23. The axis of the rope wheel 22 is an axle, and a bearing is fitted between the axle and the wheel seat 21. The drive motor 24 is connected to the axle flange on one side.

[0033] The drive motor 24 is a servo motor, and the whole machine is controlled through the monitoring room.

[0034] In the above technical solution, the drive rope 23 is made of steel wire rope. After tensioning, the drive rope 23 is driven to rotate by the rotation of the rope wheel 22. In order to prevent the drive rope 23 from slipping, damping material can be installed in the groove of the rope wheel 22 to increase the contact damping with the drive rope 23.

[0035] The length of the drive rope 23 is set according to the length of the solid waste storage area. During operation, the horizontality of the drive rope 23 must be ensured.

[0036] See Figure 2 , Figure 3 and Figure 4 As shown, the monitoring component 1 includes a guide rod structure 11, a sliding frame 12 that slides along the guide rod structure 11, and an elastic frame 13 fixed to the guide rod structure 11. A battery 14 and a wireless camera 15 are mounted on the sliding frame 12. The battery 14 supplies power to the wireless camera 15. A receiver 16 is also fixed on the sliding frame 12, and a transmitter 17 is fixed on the elastic frame 13. When the receiver 16 contacts the transmitter 17, the battery 14 begins to charge. The sliding frame 12 is fixed to the drive rope 23.

[0037] The transmitter is a wireless charging pad (including coil, inverter circuit, and control module).

[0038] The receiving end is a receiving module (including coil, rectifier circuit, BMS).

[0039] The wireless charging power is 45~80W.

[0040] Wireless cameras use 4G wireless modules or Wi-Fi wireless modules for networking.

[0041] The capacity of the battery is 10,000 to 20,000 mAh.

[0042] When the receiver slides to make contact with the receiver, the battery begins to charge.

[0043] Charging process steps

[0044] Step 1: Startup and Testing

[0045] Power on the transmitter

[0046] When the transmitter is powered on, the inverter circuit generates high-frequency AC power (such as 100-205kHz), but the coil has no energy output (standby state).

[0047] Receiver wake-up

[0048] The receiving coil on the battery side sends a signal to the transmitting end through load modulation or short-time energy pulses (such as the Qi protocol) to indicate the presence of the device.

[0049] Step 2: Handshake Communication

[0050] Agreement negotiation

[0051] The receiver transmits identification information (such as power requirements and battery type) by modulating the magnetic field (such as ASK / FSK).

[0052] The transmitter confirms protocol compatibility (such as Qi or a custom protocol) and initiates power transmission.

[0053] Foreign Object Detection (FOD)

[0054] The transmitter detects whether there are any metallic foreign objects between the coils (through power loss or impedance changes), and stops charging if any are found.

[0055] Step 3: Energy Transfer

[0056] Magnetic field coupling

[0057] The transmitting coil generates an alternating magnetic field by passing a high-frequency current through it, and the receiving coil generates alternating current through electromagnetic induction.

[0058] Resonance compensation: LC resonant circuits (series / parallel) improve transmission efficiency.

[0059] Rectification and Filtering

[0060] The receiving end uses a synchronous rectifier circuit to convert AC power to DC power and eliminates ripple through capacitor filtering.

[0061] Step 4: Battery Management (BMS Intervention)

[0062] Voltage / current regulation

[0063] The DC-DC converter at the receiving end (such as Buck-Boost) adjusts the output voltage / current to match the battery charging curve:

[0064] Lithium batteries: charge using constant current (CC) first, then constant voltage (CV).

[0065] Lead-acid batteries: multi-stage charging (trickle charge → constant current → float charge).

[0066] Real-time monitoring

[0067] The BMS monitors the battery status (voltage, temperature, SOC) to prevent overcharging / over-discharging / overheating, and cuts off charging when necessary.

[0068] Step 5: Charging Maintenance and Termination

[0069] Dynamic power adjustment

[0070] The transmitter gradually reduces its output power based on feedback from the receiver (such as an increase in battery SOC).

[0071] Fully charged but power off

[0072] When the battery reaches the termination voltage (e.g., 4.2V / cell for lithium batteries), the receiver sends a "charging complete" signal, and the transmitter shuts off the magnetic field.

[0073] Step 6: Anomaly Protection

[0074] Interruption conditions

[0075] Battery temperature exceeds limit, coil misalignment, communication interruption, overcurrent / overvoltage.

[0076] The transmitter immediately stops supplying power, and the receiver disconnects the battery.

[0077] See Figure 2 As shown, the guide rod structure 11 includes a guide rod 111 and fixed seats 112 installed at both ends of the guide rod 111. The sliding frame 12 and the elastic frame 13 are both installed through the guide rod 111.

[0078] The guide rod 111 is formed by welding multiple stainless steel rods. The diameter and wall thickness of the guide rod 111 are set according to the span to ensure that the guide rod 111 meets the installation requirements of long-distance span.

[0079] Drill holes at the top of guide rod 111, and install hoisting rods at intervals of 5 to 8 meters for hoisting. The hoisting rods are suspended and fixed to the top of the solid waste storage.

[0080] See Figure 3 and Figure 4As shown, the sliding frame 12 includes an upper clamping plate 121, a lower clamping plate 122, and a support plate 123. Bolts 124 are installed between the upper clamping plate 121 and the support plate 123 and the lower clamping plate 122. A sleeve 125 is provided on the opposite surface of the upper clamping plate 121 and the lower clamping plate 122. The drive rope 23 is clamped through the upper and lower sleeves 125. When the bolts 124 are tightened, the sleeves 125 are fixed to the drive rope 23. The upper clamping plate 121, the lower clamping plate 122, and the support plate 123 cooperate to form a guide hole 126. The guide rod 111 passes through the guide hole 126. A mounting plate 127 is welded to the top of the support plate 123. The wireless camera, the battery, and the receiver are all mounted through the mounting plate 127.

[0081] In the above technical solution, an upper clamping plate 121, a lower clamping plate 122 and a support plate 123 are used to form a guide hole 126. The upper end of the guide hole 126 has a break 199, which corresponds to the hanger rod, so that the sliding frame 12 can pass through the position where the hanger rod is installed.

[0082] Lubricant needs to be applied to the surface of the guide rod 111 to make the sliding frame 12 slide more smoothly.

[0083] In the above technical solution, the upper clamping plate 121 and the lower clamping plate 122 cooperate to achieve clamping and fixing with the drive rope 23.

[0084] This clamping and fixing method facilitates equipment debugging, adjusting the sliding frame 12 to the appropriate position.

[0085] See Figure 2 and Figure 3As shown, the elastic frame 13 includes a sleeve 131 and a sliding tube 132. A limiting plate 133 is machined at one end of the sleeve 131. The diameter of the limiting plate 133 is larger than the outer diameter of the sleeve 131. A guide rod 111 passes through the sleeve 131. A screw 134 is screwed into the outside of the limiting plate 133. After the screw 134 abuts against the guide rod 111, the position of the sleeve 131 is locked. A guide groove 135 is machined on the outer wall of the sleeve 131, extending away from the limiting plate 133. The sliding tube 132 is sleeved on the outside of the sleeve 131 and slides along the sleeve... The axial sliding of tube 131 is achieved by machining a guide strip (not shown) on the outer wall of the sliding tube 132 to match the guide groove 135. A limiting screw 136 is screwed into the end of the guide groove 135, which limits the sliding of the sliding tube 132. A spring 137 is fitted on the sleeve 131, which acts between the limiting plate 133 and the sliding tube 132. A first mounting plate 138 is installed on the outer wall of the sliding tube 132, and the transmitting end 17 is fixedly installed through the first mounting plate 138. When the receiving end contacts the transmitting end, the battery begins to charge.

[0086] In the above technical solution, through the cooperation of the slide tube 132 and the sleeve 131, and the elastic limit by the spring 137, when the receiving end contacts the transmitting end, the drive motor 24 stops. At this time, the drive rope 23 may have a certain amount of inertial movement. Through the compression of the spring, the receiving end can be given a space to move backward, so as to avoid damage to the equipment.

[0087] A control system is installed in the main control room. When the receiver comes into contact with the transmitter, the drive motor 24 is stopped synchronously.

[0088] During normal monitoring, the drive motor 24 reciprocates, causing the two monitoring components 1 to move at a speed of 5-15 seconds per meter to ensure the clarity of the captured images.

[0089] The surveillance footage is wirelessly transmitted to the cloud for storage.
