[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0021] The following describes some embodiments of the utility model in conjunction with the accompanying drawings to provide a vacuum low-temperature wolfberry drying warehouse cooling system.

[0022] Embodiment 1:

[0023] Reference Figure 1-4 , which is the first embodiment of the utility model, provides a vacuum low-temperature wolfberry drying warehouse cooling system, including a support assembly 100, a cooling mechanism 200, a vacuum mechanism 300 and a fastening assembly 400.

[0024] Specifically, the support assembly 100 includes a bracket 101, and a fixing plate 102 is provided on both sides of the bracket 101. A groove 1021 is opened on the fixing plate 102. The fixing plate 102 is connected with the protective net 103 through the groove 1021. The protective net 103 can be aligned with the groove 1021 and inserted. After the insertion, the protective net 103 plays a protective role to prevent the user from being scalded.

[0025] Specifically, the cooling mechanism 200 is arranged on the bracket 101, and the cooling mechanism 200 includes a refrigeration pump 201 arranged on the bracket 101, a condenser 202 connected to the refrigeration pump 201 by a pipeline, and an evaporator 203 connected to the condenser 202 by a pipeline. The evaporator 203 is fixedly connected to the refrigeration pump 201 by a pipeline. The refrigeration pump 201 can transport the refrigerant to the evaporator 203 through the pipeline, and then absorb the temperature in the drying chamber to achieve a cooling effect.

[0026] Specifically, the vacuum mechanism 300 includes a vacuum pump 301 arranged on the bracket 101, a vacuum tube 302 arranged at the front end of the vacuum pump 301, a valve 303 arranged on the vacuum tube 302, a vibration sensor 304 arranged at the top of the vacuum tube 302, and an audible and visual alarm 305 arranged at the top of the vibration sensor 304. The valve 303 can be opened first. After opening, the vacuum pump 301 can extract the gas in the drying chamber through the vacuum tube 302 to reduce the pressure. At the same time, the vibration sensor 304 can detect the vibration amplitude of the vacuum tube 302 in real time and transmit the signal to the external control system. When the vibration amplitude is too large, the external control system can control the audible and visual alarm 305 to alarm, so as to promptly remind people that maintenance is needed, thereby reducing the probability of failure.

[0027] It should be noted that the sound and light alarm 305 on the top of the vibration sensor 304 is electrically connected to the external control system.

[0028] Specifically, the fastening assembly 400 includes a fixing base 401 bolted to the bracket 101, a driving motor 402 arranged on the top of the fixing base 401, a screw rod 403 fixed to the output end of the driving motor 402, an upper fastening plate 404 threadedly connected to the screw rod 403, and a lower fastening plate 405 threadedly connected to the screw rod 403. The thread directions of the upper half and the lower half of the screw rod 403 are opposite, which can control the operation of the driving motor 402. The operating driving motor 402 can drive the upper fastening plate 404 and the lower fastening plate 405 to continuously approach each other through the screw rod 403, so as to clamp the vacuum tube 302, improve stability and avoid air leakage.

[0029] Furthermore, the front and rear ends of the fixing seat 401 are both provided with gaskets 406 , and the gaskets 406 are fixedly connected to the bracket 101 by bolts. The gaskets 406 can increase the contact area between the fixing seat 401 and the bracket 101 for easy installation and disassembly.

[0030] The working principle and use process of the utility model are as follows: when in use, the vibration sensor 304 can detect the vibration amplitude of the vacuum tube 302 in real time and transmit the signal to the external control system. When the vibration amplitude is too large, the external control system can control the sound and light alarm 305 to alarm, so as to remind people in time that maintenance is needed, reducing the probability of failure. At the same time, after the alarm, the external control system can control the drive motor 402 of the fastening component 400 to operate. Since the thread directions of the upper and lower parts of the screw rod 403 are opposite, the operating drive motor 402 can drive the upper fastening plate 404 and the lower fastening plate 405 to continuously approach each other through the screw rod 403, so as to clamp the vacuum tube 302, improve stability and avoid air leakage. Then the user can solve the vibration problem of the pipe fitting, and finally the protective net 103 can be inserted into the groove 1021 on the fixing plate 102. After insertion, the protective net 103 plays a protective effect to avoid burns to the user.

[0031] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
