DETAILED DESCRIPTION

[0023] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0024] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0025] like Figure 1 , Figure 2 As shown, a detection device for the in-place detection of a garbage pneumatic conveying system is based on a garbage pneumatic conveying pipeline 15, the garbage pneumatic conveying pipeline 15 is connected to a detection pipeline 14, the detection pipeline 14 is provided with an in-place detection component and an electrical box 9, the electrical box 9 is provided with a single chip microcomputer 16, and the electrical box 9 is provided with a power interface 7, an output interface 8 and a signal interface 10;

[0026] The in-position detection component includes a housing 3, a hub 4, a grating sensor and a light-transmitting plate. The hub 4 is arranged outside the housing 3, and the grating sensor is arranged inside the housing 3. The grating sensor is connected to the single-chip computer 16. The grating sensor includes a transmitting end 27 and a receiving end 20. The transmitting end 27 and the receiving end 20 are connected to the hub 4 through a transmitting end signal line 25 and a receiving end signal line 21 respectively. Two light-transmitting plates 26 are arranged on opposite side walls of the detection pipe 14, and the light-transmitting plates 26 are located inside the housing. The transmitting end 27 and the receiving end 20 are symmetrically arranged on the outside of the two light-transmitting plates 26. Among them, the grating 37 of the grating sensor is arranged corresponding to the light-transmitting plates 26.

[0027] The utility model is suitable for the arrival detection device of the garbage pneumatic conveying system. The light beam emitted by the grating sensor can pass through the light-transmitting plate. When the garbage transported in the pipeline passes through the detection range of the grating sensor, the single-chip microcomputer obtains the signal and counts it, which can be regarded as the garbage being transported to the arrival position, thereby solving the problem that it is difficult to judge whether the garbage is transported to the arrival position in the control of the garbage pneumatic conveying system.

[0028] In view of the problem that the garbage conveying process may carry mud and dirt and other attachments, when using a light-transmitting plate, the mud and dirt attached to the light-transmitting plate may affect the detection of the grating sensor, the utility model is also provided with a rotating mechanism. Figure 2 As shown, the light-transmitting plate 26 constitutes the side wall of the detection pipe 14, and the light-transmitting plate 26 is connected to a rotating mechanism, and the rotating mechanism is used to drive the light-transmitting plate 26 to move radially along the detection pipe 14 and rotate around the axis of the detection pipe 14. The side wall of the detection pipe 14 is replaced by the light-transmitting plate, and the light-transmitting plate can be freely disassembled through the rotating mechanism.

[0029] like Figure 3 As shown, the rotating mechanism includes a fixed frame 35, a sliding shaft 29, a curved slide rail 30 and a straight slide rail 33. The fixed frame 35 includes two rectangular frames. The two fixed frames 35 are connected to the sliding shaft 29. The end of the sliding shaft 29 is mounted in the straight slide rail 33 and reciprocates along the straight slide rail 33. Figure 2 , Figure 3 As shown, the light-transmitting plate 26 is an arc plate, and L-shaped transfer grooves 36 are provided at both ends of the light-transmitting plate 26. The light-transmitting plate is fixed by a fixing frame, and a sliding shaft is installed on the fixing frame, and both ends of the sliding shaft are fixed on the curved slide rail and the straight slide rail. The combination of the curved slide rail and the straight slide rail in the device can make the light-transmitting plate move away from the pipeline for a certain distance before descending, and then return to the original track when ascending.

[0030] like Figure 3 As shown, the rotating mechanism also includes a steering gear 34, an up button 12 and a down button 13, and the lower part of the straight slide rail 33 is connected to the steering gear 34, and the steering gear 34 is connected to the up button 12 and the down button 13. The shell is provided with an up button and a down button to control the up and down of the light-transmitting plate. A steering gear is provided in the device, and the steering gear preferably adopts an MG996R steering gear. When the worker presses the up or down button, the steering gear starts, drives the straight slide rail to rotate, and the slide shaft moves under the joint action of the straight slide rail and the curved slide rail, and the fixed frame and the light-transmitting plate rise or fall along the track of the curved slide rail; wherein, the steering gear drives the straight slide rail to rotate, and the slide shaft is subjected to force to slide on the curved slide rail and the straight slide rail, and the slide shaft is located at the intersection of the curved slide rail and the straight slide rail. More preferably, a bottom opening 38 is also provided at the bottom of the shell 3, and the bottom opening 38 can be used for the light-transmitting plate to pass through, and the light-transmitting plate can be manually replaced or mud can be cleaned when the light-transmitting plate descends to the bottom.

[0031] like Figure 1 As shown, the power interface is used to connect the power supply, and the single-chip microcomputer is powered by the power interface. The output interface is used to establish communication with the central control system through the signal line. The signal interface is used to connect the single-chip microcomputer. Furthermore, there is a signal interface on each side of the electrical box, and the electrical lines gathered by the hub are connected to the single-chip microcomputer through the signal interface.

[0032] like Figure 1As shown, both ends of the detection pipe 14 are connected to the garbage pneumatic conveying pipe 15 through flanges 1 and screws 2. The in-place detection device is connected between the pipes through two pairs of flanges, and is preferably installed in the horizontal pipe in the central collection station, so that the conveying state of garbage in the horizontal pipe tends to be stable and the measured result is more accurate.

[0033] like Figure 1 As shown, the in-place detection components include two, and the two in-place detection components are arranged on the detection pipe 14 at intervals. The two in-place detection components include a front-end grating sensor and a rear-end grating sensor, and the front-end grating sensor and the rear-end grating sensor are respectively installed on both sides of the electrical box. Through the matching detection of the front-end sensor and the rear-end sensor, the single-chip microcomputer can calculate the flow rate of the garbage when it passes by the time difference and the conveying distance.

[0034] like Figure 1 As shown, the electrical box 9 is located between the two in-place detection components, and the electrical box 9 is mounted on the upper part of the detection pipe 14 through the base 6. The electrical box is located at the middle top outside the pipe and is fixed on the pipe by the base to prevent the electrical box from falling off due to pipe vibration.

[0035] The utility model is suitable for the in-place detection device of the pneumatic conveying system of garbage, and is suitable for the grating sensor in-place detection device of the pneumatic conveying system of garbage. The specific working steps are as follows: Step 1: Garbage without wet mud enters the pipeline of the detection device and passes through the front sensor and the rear sensor in turn. Step 2: The laser emitted by the transmitting end of the grating sensor is received by the opposite receiving end. When the garbage is between the two ends of the sensor, it will block the laser. The sensor receives the signal and transmits it to the single-chip microcomputer. Step 3: After the front and rear sensors receive the signal, the single-chip microcomputer confirms that the garbage is in place, and calculates the conveying speed of the garbage at this moment through the time difference of the signals obtained by the front and rear sensors and the set spacing. Step 4: The single-chip microcomputer sends the obtained signal and the calculated data to the central control system of the central collection station through the output interface.

[0036] The specific steps for implementation are as follows:

[0037] Step 1: Garbage carrying wet mud enters the pipeline of the detection device and passes through the front sensor and the rear sensor in turn. Step 2: The wet mud attached to the light-transmitting plate blocks the receiving end of the grating sensor from receiving the laser, causing the group of sensors to always receive signals. Step 3: The single-chip microcomputer determines that the light-transmitting plate needs to be cleaned according to two situations: one is that the front sensor always receives a signal but the rear sensor does not receive a signal; the other is that both always receive a signal, but the timing condition is met and the signal flag is not cleared. The single-chip microcomputer sends the judgment result to the central control system of the central collection station. Step 4: The worker sees the alarm message on the interface of the central control system. Under the premise that the system stops running, he needs to manually press the down button on the shell. Step 5: The servo rotates under the control of the single-chip microcomputer, and the servo links the straight slide rail to make the slide shaft move downward along the track of the curved slide rail, that is, the light-transmitting plate installed on the fixed frame moves away from the pipeline first and then moves downward, and exits the device from the opening below the shell. At this time, the worker can clean the light-transmitting plate or replace it with a new one. Step 6: After the worker cleans or replaces the light-transmitting plate, he presses the rising button, and the device returns to the original path of step 5 to install the light-transmitting plate back on the pipeline. At this time, the worker can operate the pneumatic conveying system normally.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
