Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of liquefied natural gas storage equipment, and more specifically, to a liquefied natural gas storage equipment that is easy to control temperature. Background Technology
[0002] Natural gas is a fossil fuel containing methane as its main component and small amounts of ethane and propane. As a low-pollution energy source, natural gas has attracted attention in various technological fields. When storing natural gas, since the volume of liquefied natural gas is approximately 1 / 600th that of gaseous natural gas of the same mass, current technologies typically employ cryogenic liquefaction to liquefy gaseous natural gas and then store it in storage tanks.
[0003] Chinese Patent Publication No. CN106499942A discloses a storage tank for storing liquefied natural gas. It includes a tank body with an air inlet and a sealing valve. An adjusting screw connected to the sealing valve is located outside the air inlet. A scale is located outside the air inlet, and a pointer is located on the adjusting screw, pointing towards the scale. A locking groove is located on the inner ring of the scale. A limit control cavity is located on the adjusting screw, and a control cylinder is located within the limit control cavity. A limit rod is located on the adjusting screw and mounted on the piston shaft of the control cylinder. However, traditional liquefied natural gas (LNG) storage tanks only use tanks with walls 25-30cm thick for storage. External heat can easily penetrate the tank and enter the interior, causing the pressure inside the tank to increase continuously when the LNG is heated in summer, posing a safety hazard of tank explosion. In winter, traditional LNG storage tanks are also large and inconvenient to move and transport. Therefore, this application proposes a LNG storage device that is easy to control temperature to solve this problem.
[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
[0005] The purpose of this invention is to provide a liquefied natural gas storage device that is easy to control temperature, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a liquefied natural gas storage device with easy temperature control, comprising a storage tank, anti-wave teeth on the inner side of the storage tank, a base at the bottom of the storage tank, heat-conducting teeth on the top of the base, the heat-conducting teeth fitting into the storage tank, a cooling plate fitted to the back of the heat-conducting teeth, a ventilation groove on the back of the cooling plate, a ventilation fan inside the ventilation groove, a sensor group on one side of the heat-conducting teeth, the probe of the sensor group extending into the storage tank, portable casters at the bottom of the base, a storage groove at one end of the base, a slider inside the storage groove, a pull rod connected to one end of the slider, a controller fixedly installed inside the base, and a battery on one side of the controller.
[0007] Preferably, an air inlet valve is installed on the top of the storage tank, and an exhaust valve is installed at one end of the storage tank.
[0008] Preferably, the anti-wave teeth are welded to the storage tank, and the portable casters are bolted to the base.
[0009] Preferably, the slider is movably connected to the storage slot, and the pull rod is sleeved with the storage slot.
[0010] Preferably, the sensor group is bolted to the base, and the base is bolted to the storage tank.
[0011] Preferably, the heat-conducting teeth are fixedly connected to the base bolts, the cooling plate is fixedly connected to the base bolts, and the ventilation fan is fixedly connected to the base bolts.
[0012] Preferably, the battery is bolted to the base, and the controller is electrically connected to the sensor group, the cooling plate, and the ventilation fan.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] This utility model is a liquefied natural gas (LNG) storage device with easy temperature control. It includes a storage tank, a base, heat-conducting teeth, a cooling plate, portable casters, a storage slot, and a pull rod. The storage tank stores LNG. Pulling the pull rod out of the storage slot moves a slider along the slot. The portable casters then move the base and storage tank. When no movement is needed, the pull rod is retracted into the storage slot. The anti-wave teeth protect the LNG. When the sensor group detects that the temperature inside the storage tank is too high, the controller activates the cooling plate. The cooling plate cools the heat-conducting teeth, which dissipate the high temperature from the storage tank, thus cooling it. Simultaneously, a ventilation fan exhausts the high temperature from the back of the cooling plate through a ventilation slot. This device not only assists in effortless movement but also provides cooling and protection. Attached Figure Description

[0021] The utility model will now be further described with reference to the accompanying drawings and specific embodiments:
[0022] Please see Figure 1-3 According to an embodiment of the present invention, a liquefied natural gas storage device with easy temperature control includes a storage tank 1. The inner side of the storage tank 1 is provided with anti-wave teeth 101. A base 2 is provided at the bottom of the storage tank 1. A heat-conducting tooth 201 is provided at the top of the base 2. The heat-conducting tooth 201 is in contact with the storage tank 1. A cooling plate 202 is attached to the back of the heat-conducting tooth 201. A ventilation groove 203 is provided on the back of the cooling plate 202. A ventilation fan 204 is provided inside the ventilation groove 203. A sensor group 205 is provided on one side of the heat-conducting tooth 201. The sensor probe of the sensor assembly 205 extends into the storage tank 1. The bottom of the base 2 is equipped with portable casters 211. One end of the base 2 is equipped with a storage slot 208. The storage slot 208 is equipped with a slider 209. One end of the slider 209 is connected to a pull rod 210. The controller 206 is fixedly installed inside the base 2. A battery 207 is provided on one side of the controller 206. This utility model uses heat-conducting teeth and a cooling plate to cool down the storage tank, which can effectively prevent the temperature inside the storage tank from getting too high and achieve a cooling and protection effect.
[0023] According to the above-described scheme of this utility model, an air inlet valve 102 is installed on the top of the storage tank 1, and an exhaust valve 103 is installed at one end of the storage tank 1 for liquid inlet and liquid outlet.
[0024] According to the above-mentioned solution of this utility model, the anti-wave tooth 101 is welded to the storage tank 1, the portable caster 211 is bolted to the base 2 to facilitate the movement of the storage tank 1, the slider 209 is movably connected to the storage slot 208, and the pull rod 210 is sleeved with the storage slot 208 to facilitate the extension and retraction of the pull rod 210.
[0025] According to the above-described scheme of this utility model, the sensor group 205 is bolted to the base 2. The sensor group 205 includes a temperature sensor and a pressure sensor, which are used to detect the temperature and pressure values inside the storage tank 1. The base 2 is bolted to the storage tank 1. The heat-conducting tooth 201 is bolted to the base 2. The cooling plate 202 is bolted to the base 2. The ventilation fan 204 is bolted to the base 2. The cooling plate 202 is made of a semiconductor cooling chip and is used for heat conduction and cooling.
[0026] According to the above-mentioned scheme of this utility model, the storage battery 207 is fixedly connected to the base 2 with bolts, and the controller 206 is electrically connected to the sensor group 205, the cooling plate 202 and the ventilation fan 204 respectively.
