Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of measuring equipment, in particular to a device for measuring the remaining loading amount in a barrel. Background Art
[0002] Beer kegs used for storing beer in bars or breweries, especially stainless steel beer kegs, are all equipped with beer spears, which are used to seal the beer kegs in cooperation with various dispensers. The sealed beer keg will only be opened when it is refilled, so once the beer keg is sealed, the remaining load in the keg cannot be intuitively understood. In the prior art, the confirmation of the remaining load in the keg is mostly done by knocking on the barrel of the beer keg to judge the remaining amount from the sound, or by using equipment such as pressure sensors to measure the pressure of the beer on the tank body, and calculating the weight and quantity of the beer by the pressure value. Both methods cannot accurately obtain the remaining load in the keg, and can only make a rough judgment based on experience. Utility Model Content
[0003] The utility model aims to provide a device for measuring the remaining load in a barrel, so as to solve the problem in the background technology that the remaining load in the barrel cannot be accurately obtained after the beer barrel is packaged.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is a device for measuring the remaining load in the barrel, which is applied to a beer barrel, wherein the beer barrel includes a beer spear and a water outlet, wherein the beer spear extends along a first direction, and the water outlet is arranged at the bottom of the side wall of the beer barrel, and the device for measuring the remaining load in the barrel includes a first sleeve ring device and a second sleeve ring device, wherein: the first sleeve ring device is located at the bottom of the beer spear and is sleeved on the beer spear. A liquid flow sensor is arranged in the first sleeve ring device, which is used to detect the outflow speed of the liquid in the beer barrel through the liquid flow sensor. The faster the outflow speed, the higher the frequency of the pulse signal generated by the liquid flow sensor. The second sleeve ring device is located at the top of the beer spear and is sleeved on the beer spear. A battery pack is arranged in the second sleeve ring device. The battery pack is connected to the liquid flow sensor circuit to provide a working voltage.
[0005] The barrel remaining load measuring device provided by the utility model is suitable for measuring the liquid in the beer barrel. The beer barrel includes a beer spear extending along a first direction, and a water outlet located at the bottom of the side wall of the beer barrel. The barrel remaining load measuring device includes a first sleeve ring device and a second sleeve ring device. The first sleeve ring device provided with a liquid flow sensor is sleeved on the bottom of the beer spear, so that the liquid flow sensor can detect the flow of liquid more easily and ensure the accuracy of the detection result. The second sleeve ring device is sleeved on the top of the beer spear, and the battery pack arranged inside provides the liquid flow sensor with a working voltage. In addition, the first sleeve ring device and the second sleeve ring device are both sleeved on the beer spear, which can adapt to a variety of beer spear / dispenser combinations, not a specific model.
[0006] When the measured liquid flows through the liquid flow sensor, the impeller inside is forced to rotate under the action of the fluid, and its speed is proportional to the average flow rate of the pipeline. The rotation of the impeller periodically changes the magnetic resistance value of the magnetic circuit, and the magnetic flux in the detection coil changes periodically, generating an induced electromotive force with the same frequency as the blade rotation frequency, which is converted and processed after amplification to output a pulse signal.
[0007] In some embodiments, a circuit board is also provided in the second ring device, and the circuit board is connected to the liquid flow sensor and the battery pack circuit. The circuit board includes a central processing chip for receiving and processing the pulse signal emitted by the liquid flow sensor, generating the remaining load information in the barrel, and sending it to an external terminal device.
[0008] By adopting the above technical solution, a circuit board is also provided in the second ring device, and the pulse signal emitted by the flow sensor is received and processed by the central processing chip in the circuit board, and the different remaining loads of the beer barrel are reflected in real time through the different pulse frequencies of the pulse signal.
[0009] In some embodiments, the circuit board further includes a Wifi communication chip for generating location information of the beer barrel and sending the information to an external terminal device.
[0010] With the above technical solution, beer barrels are usually placed indoors or in warehouses and cannot be located by GPS, but can be more accurately located through Wifi communication chips, so that the location where the barrels are stored can be accurately found indoors or in warehouses.
[0011] In some embodiments, a temperature sensor is further provided in the first collar device for detecting the temperature in the beer barrel and transmitting the temperature to an external terminal device.
[0012] By adopting the above technical solution, the temperature in the barrel is monitored in real time using a temperature sensor. The storage of the liquid in the barrel requires a suitable temperature. Too high or too low a temperature will affect the quality of the liquid in the barrel, so the temperature in the barrel needs to be detected.
[0013] In some embodiments, a gravity sensor is further provided in the first collar device for detecting the placement state of the beer keg and sending the detection state to an external terminal device. The placement state includes a horizontal state and a vertical state. Under the same flow rate, the pulse frequency of the vertical state is greater than the pulse frequency of the horizontal state.
[0014] By adopting the above technical solution, the placement of the wine barrel is judged through the gravity sensor, that is, whether it is in a horizontal state or a vertical state. Because the placement position of the wine barrel is different, the pulse frequency generated will also be different. Therefore, the corresponding flow rate measurement true value is called according to the placement position of the wine barrel to measure the remaining load in the barrel.
[0015] In some embodiments, the barrel remaining load measurement device further comprises an antenna. The antenna is disposed on the top of the beer barrel and fixedly connected to the beer spear. The antenna is used to be connected to the circuit board via an antenna extension line, and is used to send the remaining load information, the position information and the placement status of the beer barrel to an external terminal device.
[0016] Using the above technical solution, beer barrels are mostly made of stainless steel, which is not convenient for installing and fixing the antenna. However, the middle cylindrical part of the beer spear can pass through the outside of the barrel, so this part is reserved for the antenna, and the relevant information of the beer barrel is transmitted to the external terminal device through the antenna.
[0017] In some embodiments, the device for measuring the remaining load in the barrel further includes a low power consumption mode, wherein the liquid flow sensor and the circuit board are both in a sleep state when no liquid flows out of the beer barrel.
[0018] With the above technical solution, when there is no liquid flowing in the beer barrel, multiple sensors and the central processing chip are in a dormant state, i.e., a low power consumption mode. Only when the beer flows or the position of the beer barrel moves, multiple sensors are triggered to start and perform corresponding detection. By setting the low power consumption mode, the use time of the remaining load measuring device in the barrel can be extended, the number of battery replacements can be reduced, and the service life of multiple sensors can be extended.
[0019] In some embodiments, both the first collar device and the second collar device are sealed with waterproof materials.
[0020] By adopting the above technical solution, the first ring device and the second ring device are both sealed with waterproof materials to prevent liquid in the barrel from splashing in and affecting the normal and safe use of the remaining load measuring device in the barrel.

[0031] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

Figure 1 ; Figure 2 The structure diagram of a device for measuring the remaining load in a barrel provided by the embodiment of the utility model is shown. Figure 2 .
[0033] like Figure 1 and Figure 2 As shown, Figure 1 The present application shows a barrel remaining load measuring device, which is applied to a beer barrel. The beer barrel includes a beer spear and a water outlet. The beer spear is along a first direction ( Figure 1 The water outlet is arranged at the bottom of the side wall of the beer barrel, and the remaining load measuring device in the barrel includes a first ring device and a second ring device, wherein: the first ring device is located at the bottom of the beer spear and is sleeved on the beer spear. A liquid flow sensor is arranged in the first ring device, which is used to detect the outflow speed of the liquid in the beer barrel through the liquid flow sensor. The faster the outflow speed, the higher the frequency of the pulse signal generated by the liquid flow sensor. The second ring device is located at the top of the beer spear and is sleeved on the beer spear. A battery pack is arranged in the second ring device. The battery pack is connected to the liquid flow sensor circuit to provide a working voltage.
[0034] The barrel remaining load measuring device provided in the present application is suitable for measuring the liquid in the beer barrel. The beer barrel includes a beer spear extending along a first direction, and a water outlet located at the bottom of the side wall of the beer barrel. The barrel remaining load measuring device includes a first sleeve ring device and a second sleeve ring device. The first sleeve ring device provided with a liquid flow sensor is sleeved on the bottom of the beer spear, which can make it easier for the liquid flow sensor to detect the flow of liquid and ensure the accuracy of the detection result. The second sleeve ring device is sleeved on the top of the beer spear, and the battery pack arranged inside provides the liquid flow sensor with a working voltage, and the battery pack is 4 AAA7 batteries. In addition, the first sleeve ring device and the second sleeve ring device are both sleeved on the beer spear, which can adapt to a variety of beer spear / dispenser combinations, not specific to a certain model.
[0035] When the measured liquid flows through the liquid flow sensor, the impeller inside is forced to rotate under the action of the fluid, and its speed is proportional to the average flow rate of the pipeline. The rotation of the impeller periodically changes the magnetic resistance value of the magnetic circuit, and the magnetic flux in the detection coil changes periodically, generating an induced electromotive force with the same frequency as the blade rotation frequency, which is converted and processed after amplification to output a pulse signal.
[0036] refer to Figure 3 , Figure 3 The structure diagram of a device for measuring the remaining load in a barrel provided by the utility model is shown. Figure 3 .
[0037] In some embodiments, reference Figure 3 A circuit board is also provided in the second ring device, which is connected to the liquid flow sensor and the battery pack circuit. The circuit board includes a central processing chip for receiving and processing the pulse signal sent by the liquid flow sensor, generating the remaining load information in the barrel, and sending it to the external terminal device.
[0038] Exemplarily, a circuit board is also provided in the second ring device, and the pulse signal emitted by the flow sensor is received and processed by the central processing chip in the circuit board, and the different remaining loads of the beer barrel are reflected in real time through the different pulse frequencies of the pulse signal.
[0039] In some embodiments, reference Figure 3 ,The circuit board also includes a Wifi communication chip for generating the location information of the beer barrel and sending it to an external terminal device.
[0040] For example, beer barrels are usually placed indoors or in warehouses and cannot be located by GPS, but can be more accurately located by a Wifi communication chip, so that the location where the barrels are stored can be accurately found indoors or in the warehouse.
[0041] In some embodiments, a temperature sensor is also provided in the first ring device for detecting the temperature in the beer barrel and sending the temperature to an external terminal device.
[0042] For example, a temperature sensor is used to monitor the temperature in the barrel in real time. The storage of the liquid in the barrel requires a suitable temperature. Too high or too low a temperature will affect the quality of the liquid in the barrel, so the temperature in the barrel needs to be detected.
[0043] refer to Figure 4 , Figure 4 A curve chart of flow rate and pulse frequency of a device for measuring the remaining load in a barrel provided by the utility model is shown.
[0044] In some embodiments, a gravity sensor is further provided in the first ring device to detect the placement state of the beer keg and send it to an external terminal device. The placement state includes a horizontal state and a vertical state. Under the same flow rate, the pulse frequency of the vertical state is greater than the pulse frequency of the horizontal state.
[0045] For example, the gravity sensor is used to sense and judge the placement of the wine barrel, that is, whether it is in a horizontal state or a vertical state. Because the placement of the wine barrel is different, the pulse frequency generated will also be different, such as Figure 4 As shown in the figure, within the test range of 2L / min to 10L / min, as the liquid flow rate increases, the pulse frequency generated by the liquid flow sensor also gradually increases. It can be seen that the flow rate and the pulse frequency are positively correlated, and at the same flow rate, the pulse frequency in the vertical state is greater than the pulse frequency in the horizontal state. The curve table of flow rate and pulse frequency is as follows:
[0046] Flow characteristics laboratory measured parameters comparison tablePulse (Hz)
[0047]
[0048] Therefore, the corresponding flow rate measurement true value is called according to the placement of the wine barrel, and the remaining load in the barrel is measured.
[0049] In some embodiments, the barrel remaining load measuring device further comprises an antenna. The antenna is disposed on the top of the beer barrel and fixedly connected to the beer spear. The antenna is used to be connected to the circuit board through an antenna extension line, and is used to send the remaining load information, position information and placement status of the beer barrel to an external terminal device.
[0050] For example, beer barrels are mostly made of stainless steel, which is not convenient for installing and fixing antennas, but the middle cylindrical part of the beer spear can pass through the outside of the barrel, so this part is reserved for the antenna. The remaining load measurement device in the barrel transmits the remaining load information, temperature information and placement information of the beer barrel to the wireless network through the wireless protocol, and adopts 4G communication methods such as NB-IoT and LTE to transmit these data to terminal devices such as user mobile phones in a timely manner, so as to remotely monitor the beer barrel in real time.
[0051] In some embodiments, the device for measuring the remaining load in the barrel also includes a low power consumption mode. In the low power consumption mode, when no liquid flows out of the beer barrel, the liquid flow sensor and the circuit board are both in a dormant state.
[0052] For example, when there is no liquid flowing in the beer barrel, the multiple sensors and the central processing chip are in a dormant state, i.e., a low power consumption mode. Only when the beer flows or the position of the beer barrel moves, the multiple sensors are triggered to start and perform corresponding detection. By setting the low power consumption mode, the use time of the remaining load measurement device in the barrel can be extended, the number of battery replacements can be reduced, and the service life of the multiple sensors can be extended.
[0053] In some embodiments, the first loop device and the second loop device are both sealed using a waterproof material.
[0054] Exemplarily, both the first collar device and the second collar device are sealed with waterproof materials to prevent liquid in the barrel from splashing in and affecting the normal and safe use of the remaining load measuring device in the barrel.
[0055] The above implementation modes are only for illustrating the technical concept and features of the utility model, and their purpose is to allow people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
