Description

Technical Field

[0001] The utility model relates to the technical field of instrument cleaning, in particular to an automatic instrument cleaning device. Background Art

[0002] Instruments are one of the most widely used equipment in modern factories. They detect various production indicators to help people manage production. The sensing element (i.e., probe) of the instrument is in contact with the measured object for a long time, and it is inevitable that it will be covered by dust, mud or other debris, which affects the accuracy of the instrument measurement data. In order to maintain the accuracy of the instrument detection data, the sensing element (i.e., probe) of the instrument needs to be cleaned. At present, the cleaning method of the instrument probe is mostly manual cleaning, but due to inconvenient operation, high safety risks, and lack of responsibility of workers, the manual cleaning frequency of the instrument probe is not enough, or the cleaning is not thorough, which cannot meet the needs.

[0003] For this reason, some technologies that can automatically clean instrument probes have also appeared on the market. For example, the patent technology with application number CN202122842234.9 discloses a sewage online detection instrument probe cleaning device, which cleans the online detection probe online by cleaning water pipes, cleaning nozzles, ultrasonic cleaning devices and electrical control cabinets, etc. It is convenient and reliable and reduces manual operation. However, this technology is only for cleaning the probe of sewage detection instruments, and cannot be used for cleaning image acquisition instruments such as monitoring instruments; in addition, because its cleaning nozzle is located directly below the detection probe and facing the detection probe, such a setting will affect the normal use of ultrasonic, image acquisition and other instruments, and the scope of use is relatively limited. For this reason, the present application provides an automatic instrument cleaning device with better applicability and can be applied to a variety of situations. Utility Model Content

[0004] In order to solve the above problems, the present application provides an automatic instrument cleaning device, which has wider applicability and can clean the probes of various instruments.

[0005] The purpose of the utility model is achieved through the following technical solutions: an automatic instrument cleaning device, comprising:

[0006] A pipeline is used to transport a cleaning medium; a nozzle is connected to the pipeline and is arranged on one side of the instrument probe, and a cleaning end of the nozzle extends to the lower side of the instrument probe.

[0007] Among them, the end of the nozzle cleaning end contracts inward to form an inverted cone section, and a side nozzle facing the bottom of the instrument probe is opened on the side wall of the nozzle cleaning end, and the side nozzle is located above the inverted cone section. The cleaning medium in the nozzle is sprayed to the bottom of the instrument probe after passing through the side nozzle.

[0008] In some embodiments, the end of the nozzle cleaning end is provided with a downwardly facing bottom nozzle, and the bottom nozzle can flush the entangled objects at the bottom of the nozzle.

[0009] The pipeline is provided with a control valve, and the control valve is connected with a valve controller for controlling the timing switch thereof.

[0010] The nozzle is fixed to one side of the instrument probe by a fastener.

[0011] Compared with the prior art, this application has the following beneficial effects:

[0012] The utility model sets the cleaning end of the nozzle as an inverted cone section, and sets a side nozzle toward the bottom of the instrument probe above the inverted cone section. Under the action of pressure, the cleaning medium in the nozzle is blocked by the inverted cone section and sprayed from the side nozzle toward the bottom of the instrument probe to clean the instrument control head. The nozzle will not affect the normal operation of the instrument probe. The utility model can be applied not only to sewage detection instruments, but also to the cleaning of image acquisition instruments, ultrasonic instruments and the like, and has wider applicability.

[0019] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0020] Example

[0021] like Figure 1 As shown, this embodiment discloses an automatic instrument cleaning device, which includes a pipeline 1 and a nozzle 4, and the nozzle 4 is connected to the pipeline 1. The cleaning medium is pumped into the pipeline 1 by an external device and then transported to the nozzle 4.

[0022] The nozzle 4 is fixed to the side of the meter probe 5 by a fastener 6, and the cleaning end of the nozzle 4 extends downward to the side of the meter probe 5. The fastener 6 can be a cable tie, a fixing frame, etc., which only needs to fix the nozzle 4 and the meter probe 5 together.

[0023] like Figure 2 , 3 As shown, the end of the cleaning end of the nozzle 4 gradually shrinks inward to form an inverted cone section 44, and the inner diameter of the inverted cone section 44 gradually decreases from top to bottom. In addition, a side nozzle 42 facing the bottom of the instrument probe 5 is opened on the side wall of the cleaning end of the nozzle 4, and the side nozzle 42 is located above the inverted cone section 44. Therefore, the high-pressure cleaning medium entering the nozzle 4 through the pipeline 1 hits the side wall of the inverted cone section 44 and is reversely ejected from the side nozzle 42 to the bottom of the instrument probe 5 to clean the instrument probe 5.

[0024] In the specific configuration, a slit can be cut in the side wall of the cleaning end of the nozzle 4 on the side facing the instrument probe 5 along the vertical direction of the side wall, and the lower end of the side wall above the slit is bent toward the inside of the nozzle 4, thereby forming a guide slope 43 facing the bottom of the instrument probe 5, and the side nozzle 42 facing the bottom of the instrument probe 5 is formed between the guide slope 43 and the lower pipe wall. When the medium is sprayed out from the side nozzle 42, it can be better sprayed toward the bottom of the instrument probe 5 due to the guiding effect of the guide slope 43.

[0025] This embodiment cleans the instrument probe 5 by setting a side nozzle 42 on the nozzle 4 to avoid the nozzle 4 being directly below the instrument probe 5 and affecting the normal operation of the instrument probe. Therefore, this embodiment can be applied not only to the cleaning of sewage detection instruments, but also to the cleaning of image acquisition instruments, and has stronger applicability. When in use, the cleaning medium can be air or cleaning water according to the application occasion; for example, when cleaning the detection probe in the biological reaction tank of a sewage treatment plant, the condensation water pipe in the aerobic zone of the biological tank can be connected to the pipe 1, and the waste condensation water can be used as the cleaning medium. When cleaning the probe of the security instrument on the ground, the cleaning medium can be air.

[0026] In some embodiments, the end of the cleaning end of the nozzle 4 is provided with a downward bottom nozzle 41. When the detection object in the use scenario contains debris that is easy to cause entanglement, the medium sprayed from the bottom nozzle 41 flushes the bottom of the nozzle 4 to prevent the debris from entanglement with the nozzle 4.

[0027] In addition, a control valve 2 is provided on the pipeline 1, and the control valve 2 can be implemented by a solenoid valve. The control valve 2 is a normally closed type, and is connected to a valve controller 3. The valve controller 3 is used to control the timing opening and closing of the control valve 2. The valve controller 3 is composed of a time controller, a time relay, an AC contactor and other units. The time controller is preset with a cleaning time and a cleaning interval time. When the set cleaning interval time is reached, the time relay connects the power supply of the control valve 2 through the AC contactor, and the control valve 2 is immediately opened for cleaning; after the cleaning time is reached, the control valve 2 is closed, and the equipment enters the next cycle. The valve controller 3 for controlling the timing switch of the valve is a mature technology, and will not be described in detail here.

[0028] The automatic instrument cleaning device of this embodiment not only saves a lot of manpower and realizes the intrinsic safety of the instrument cleaning operation, but also the high-frequency instrument cleaning ensures the accuracy of the instrument data and is more conducive to production management.

[0029] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.

[0030] In addition, the above specific embodiments are exemplary, and those skilled in the art can come up with various solutions inspired by the disclosure of the utility model, and these solutions also belong to the disclosure scope of the utility model and fall within the protection scope of the utility model. Those skilled in the art should understand that the utility model specification and its drawings are illustrative and do not constitute a limitation of the claims.
