Description

Technical Field

[0001] The present application relates to the technical field of cleaning of air-conditioning circulation pipes, and in particular to a counting rubber ball cleaning device and a control method. Background Art

[0002] The condenser rubber ball online cleaning equipment uses the rubber ball flowing with the water flow to physically rub the inner wall of the heat exchange pipe to achieve the cleaning effect. The rubber ball relies on the water pressure difference to scrub the dirt on the inner wall of the heat exchange pipe. At the cooling water outlet, the rubber ball is recovered to the ball machine through the ball collecting device to form a cleaning cycle. The rubber ball online cleaning equipment is divided into "pipeline type" and "end cover type". The end cover type rubber ball cleaning equipment is directly installed on the refrigeration host and occupies a small space. When the equipment serves the ball, one side of the ball valve is connected to the water inlet pipe, and the other side is connected to the water inlet side of the equipment body. The pressure difference is used to send the rubber ball into the water inlet pipe, and the surface of the rubber ball is used to wipe the pipe wall to achieve the cleaning effect.

The cleaned rubber balls are put into the collecting bucket and moved to the inside of the collecting bucket through the ball outlet and the conduit. During the transfer process, the rubber balls are restricted by the push rod. When the scraper blade moves to the top of the ball outlet, the rubber balls are squeezed. The push rod moves outward to drive the magnetic plate to move, so that the coil generates an induced current and is recorded by the processor, so that the number of rubber balls can be summarized and recorded.

[0042] Embodiment 1:

[0043] The present application embodiment provides a countable rubber ball cleaning device, comprising:

[0044] The frame 1 is provided with a ball-serving chamber 101 and a collecting chamber 102, wherein the ball-serving chamber 101 is in communication with the collecting chamber 102;

[0045] The ball collecting funnel 2 is arranged at the connection between the ball serving chamber 101 and the collecting chamber 102. The side of the ball collecting funnel 2 with a larger opening area is close to the collecting chamber 102. The side of the ball collecting funnel 2 with a smaller opening area is also provided with a valve 21.

[0046] A plurality of rubber balls 3 are arranged in the ball-serving cavity 101, and each of the rubber balls 3 is provided with an ultra-high frequency anti-metal tag 31;

[0047] A reader / writer 4, fixedly connected to the rack 1, for reading or writing to each of the UHF anti-metal tags 31;

[0048] The controller 5 is connected to the reader / writer 4 for communication, and is used for receiving information read by the reader / writer 4 or transmitting information to be written to the reader / writer 4 .

[0049] Exemplarily, the frame 1 is implemented as a serving machine body of a cleaning device, and a base 11 is fixedly connected to the bottom of the frame 1. The base 11 is provided with a plurality of through holes for fixing the frame 1. A water pump 12 is also connected to one side of the frame 1. At the same time, the frame 1 is also provided with two cavities connected up and down, wherein the lower cavity is a serving cavity 101, and the upper cavity is a collecting cavity 102. Under the action of the water pump 12, the cleaning water moves from the serving cavity 101 to the air conditioner pipe to be cleaned, and then flows into the collecting cavity 102.

[0050] The ball collecting funnel 2 is in the shape of an inverted truncated cone, and the inner diameter of the ball collecting funnel 2 gradually decreases along its height direction from the collecting chamber 102 toward the ball serving chamber 101. The outer wall of the ball collecting funnel 2 with a larger cross-sectional area fits with the inner wall of the collecting chamber 102, and the ball collecting funnel 2 is welded and fixed to the inner wall of the collecting chamber 102. A valve 21 is also connected to the side of the ball collecting funnel 2 close to the ball serving chamber 101. The valve 21 can be set as a solenoid valve to separate the collecting chamber 102 and the ball serving chamber 101.

[0051] A plurality of rubber balls 3 are placed in the ball-serving cavity 101, and the material of the rubber balls 3 can be implemented as rubber. An ultra-high frequency anti-metal tag 31 with a waterproof grade of IP68 is implanted in each rubber ball 3. The size of the ultra-high frequency anti-metal tag 31 is 5 mm in diameter, 4 mm in thickness, and has an operating frequency of 902-928 MHZ. It uses the chip Alien higgs-3, can store 512 bits of user information, and supports a maximum read and write distance of 1 m.

[0052] The reader / writer 4 is implemented as a device for reading and writing the ultra-high frequency anti-metal tag 31, and the reader / writer 4 supports the ISO18000-6C communication protocol. The shell of the reader / writer 4 is fixedly connected to the frame 1 by bolt connection. The data acquisition end of the reader / writer 4 is arranged toward the side of the collection cavity 102, and is used to write information to the ultra-high frequency anti-metal tag 31 of the rubber ball 3 in the serving cavity 101 or read the information of the rubber ball 3 in the collecting cavity 102.

[0053] The controller 5 can be implemented as a microcontroller unit (MCU) for receiving information obtained by the reader 4 or transmitting the information to be read or written to the reader 4, so that the reader 4 can write the information to be read or written into the UHF anti-metal tag 31. At the same time, the controller 5 can also be connected to the display for communication to display the information of the read rubber ball 3 on the screen of the display.

[0054] When the rubber ball 3 implanted with the UHF anti-metal tag 31 is sucked into the collecting chamber 102 of the rack 1, it is intercepted by the ball collecting funnel 2. At the same time, the reader 4 on the top of the rack 1 starts to automatically read the rubber ball 3 in the ball collecting funnel 2 through the ISO18000-6C communication protocol, and feeds back the read information to the controller 5, and the controller 5 displays the detailed information and quantity of the rubber ball 3 on the screen; then the valve 21 at the bottom of the ball collecting funnel 2 is opened, and the rubber ball 3 falls into the ball issuing chamber 101 by its own gravity, thereby realizing a rubber ball 3 cleaning and rubber ball 3 counting process.

[0055] In the countable rubber ball cleaning device provided in the embodiment of the present application, a reader / writer 4 is arranged at the frame 1, and the reader / writer 4 is used to obtain the information to be read and written stored in the controller 5, and the information to be read and written is written into the ultra-high frequency anti-metal tag 31 in the rubber ball 3. After the rubber ball 3 moves to the collecting chamber 102 through the ball-issuing chamber 101, the reader / writer 4 is used to read the ultra-high frequency anti-metal tag 31 in the rubber ball 3 in the collecting chamber 102, so as to obtain the information corresponding to the rubber ball 3 collected in the collecting chamber 102, and transmit the collected information to the controller 5, which determines the collection status of the rubber ball 3 based on the collected information, thereby effectively solving the defect of the currently disclosed rubber ball cleaning device that different specifications of catheters are replaced for rubber balls 3 of different specifications before counting the rubber balls 3, realizing the counting of multiple rubber balls 3 at the same time, and being able to count rubber balls 3 of different specifications, thereby improving the speed and applicability of counting the rubber balls 3.

[0056] In a possible implementation, the valve 21 includes:

[0057] The connection block 211 is provided with a plurality of release holes 2112 for the rubber ball 3 to pass through, the connection block 211 is further provided with a connection hole 2111, and an electromagnet is further provided in the connection block 211;

[0058] A magnetic blocking block 212 is disposed below the connecting block 211 and is used to fit with the lower surface of the connecting block 211 under the action of the electromagnet;

[0059] The guide rod 213 is fixedly connected to the magnetic blocking block 212 and passes through the connecting hole 2111. The guide rod 213 is perpendicular to the surface of the magnetic blocking block 212. The end of the guide rod 213 away from the magnetic blocking block 212 is also connected to an anti-fall block 214, and the outer diameter of the anti-fall block 214 is larger than the inner diameter of the connecting hole 2111.

[0060] In order to further improve the convenience of the valve 21 sealing the rubber ball 3, the outer wall of the connecting block 211 is provided with a thread, and the connecting block 211 is fixedly connected to the ball receiving funnel 2 by a threaded connection. A connecting hole 2111 is provided at the center of the connecting block 211, and 9 release holes 2112 that are arranged vertically through the connecting block 211 can be provided. The size of each release hole 2112 is larger than the outer diameter of the rubber ball 3, and the rubber ball 3 can fall into the ball serving cavity 101 along the release hole 2112; an electromagnet is also buried in the connecting block 211, and the control end of the electromagnet is connected to the controller 5.

[0061] The top section of the magnetic blocking block 212 fits with the bottom section of the connecting block 211. The magnetic blocking block 212 can fit tightly with the bottom wall of the connecting block 211 under the action of the electromagnet, and can seal the rubber ball 3 in the ball receiving funnel 2, thereby facilitating reading by the reader 4.

[0062] The guide rod 213 and the magnetic blocking block 212 are connected as a whole by bonding. The guide rod 213 is perpendicular to the top surface of the magnetic blocking block 212. The outer diameter of the guide rod 213 is smaller than the inner diameter of the connecting hole 2111. The guide rod 213 passes through the connecting hole 2111 and can slide up and down along the connecting hole 2111. The top of the guide rod 213 is also connected with an anti-fall block 214 by an integral molding manner. The anti-fall block 214 is implemented as a spherical center. The outer diameter of the anti-fall block 214 is larger than the inner diameter of the connecting hole 2111, which is used to keep the magnetic connecting block 211 within the action range of the electromagnet to prevent the magnetic blocking block 212 from falling off the connecting block 211, thereby ensuring that the magnetic connecting block 211 is blocked or opened for multiple release holes 2112 under the action of the electromagnet.

[0063] In a possible implementation, the side of the connecting block 211 away from the magnetic blocking block 212 is conical, and the connecting hole 2111 is set through the center line of the connecting block 211, and the length of the outer wall of the release hole 2112 close to the connecting hole 2111 is smaller than the length of the outer wall of the release hole 2112 away from the connecting hole 2111.

[0064] In order to prevent the rubber ball 3 from being stuck by the edges between adjacent release holes 2112, the side of the connecting block 211 away from the magnetic blocking block 212 is implemented as a cone, so that the rubber ball 3 can slide along the inclined outer wall toward the larger opening of the release hole 2112, so that the rubber ball 3 can quickly escape from the ball collecting funnel 2, reducing the probability of the rubber ball 3 in the ball collecting funnel 2 getting stuck.

[0065] In a possible implementation, a collection hole is provided on a side of the rack 1 close to the reader 4, a transparent plate 6 is fixedly connected to the collection hole, and a signal transmitting port and a signal receiving port of the reader 4 are both arranged toward the collection hole.

[0066] The collection hole is provided to reduce the shielding of the rack 1 on the information to be read and written by the reader 4. Meanwhile, the transparent plate 6 can be implemented as an acrylic plate. The transparent plate 6 and the rack 1 are connected as a whole by bonding. The reader 4 can write to or read the information in the UHF anti-metal tag 31 through the transparent plate 6.

[0067] In a possible implementation, the communication connection between the reader / writer 4 and the controller 5 includes: network cable communication or optical fiber communication.

[0068] In order to reduce the interference between the reader / writer 4 and the controller 5, the reader / writer 4 and the controller 5 are connected for communication via a network cable. The network cable between the reader / writer 4 and the controller 5 can be implemented as an RS485 communication cable, which reduces the interference of the outside world on the information transmitted between the reader / writer 4 and the controller 5 through its own outer shielding layer.

At the same time, the water outlet pipe 7 is arranged horizontally, and the water outlet pipe 7 is connected to the frame 1 as a whole by welding. The end of the water outlet pipe 7 away from the frame 1 is also provided with a first flange for connecting the pipe to be cleaned.

[0078] The reserved memory is used to store the kill password and access password, and the password area is up to 2 characters long, corresponding to 4 bytes. The electronic product code memory is used to store the EPC number, which is 96 bits and corresponds to 12 bytes. The tag identification number memory stores the tag identification number.

[0084] Embodiment 2:

[0085] Based on the above embodiments, the present application also provides a control method for a countable rubber ball cleaning device, including:

[0086] S01, using the reader / writer 4 to write the information to be read and written provided by the database, and writing the information to be read and written into each rubber ball 3 in the serving cavity 101;

[0087] S02, according to the rubber ball 3 obtained in the collection chamber 102, the reader 4 is used to perform reading, obtain the information of the rubber ball 3 in the collection chamber 102, and transmit the obtained information to the controller 5;

[0091] Exemplarily, the pre-written content is first written into the UHF anti-metal tag 31 in the rubber ball 3 through the reader 4. When the rubber ball 3 is sent out of the ball-serving cavity 101, the reader 4 turns on the group reading function, and the reader 4 reads frames continuously. As long as the rubber ball 3 is within the reading range of the reader, the reader 4 sends a notification frame each time it reads an UHF anti-metal tag 31, and when the reader 4 reads multiple UHF anti-metal tags 31, it sends multiple notification frames. The content read from the UHF anti-metal tag 31 is reported to the controller 5, and the controller 5 compares and analyzes the read content with the database content, and determines whether there is a lost ball or a bad ball during the ball receiving process through a preset algorithm.

[0092] If there is a situation of lost or broken ball, an alarm signal is generated to instruct the staff to perform maintenance; otherwise, the controller 5 determines that the ball is successfully collected this time, and the reader 4 stops reading; at the same time, the controller 5 controls the valve 21 at the bottom of the ball collecting funnel 2 to open, and the rubber ball 3 falls into the ball serving cavity 101 by its own gravity, waiting for the next serve, and this cycle is repeated.

Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the present application.
