Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a pressure intelligent early warning and control device for refrigeration equipment. Background Technology

[0002] Refrigeration equipment refers to equipment that uses energy consumption and changes in the state of refrigerant to transfer heat, thereby reducing the temperature of a specific space or object. It mainly includes components such as compressors, condensers, evaporators, and expansion valves.

[0003] When refrigeration equipment is running, the compressor and other components often experience excessive pressure due to poor heat dissipation, excessive refrigerant, or system blockage. Excessive pressure can overload the compressor, accelerate component wear, and even cause accidents such as leaks and explosions. The intelligent pressure early warning and control device can monitor the pressure in real time, provide timely warnings when abnormalities occur, and automatically adjust equipment parameters to ensure safety.

[0004] However, existing raw material micronization equipment has the following shortcomings:

[0005] In the existing technology, pressure intelligent early warning control devices usually use pressure sensors to monitor the pressure values ​​of key parts of refrigeration equipment, thereby providing early warning of abnormal pressure conditions. However, over time or when the refrigeration equipment is used in harsh environments, the electronic components inside the pressure sensor or control device will age or be damaged, making it impossible to accurately provide feedback when the pressure is too high, resulting in untimely early warning.

[0006] Therefore, we propose an intelligent pressure early warning and control device for refrigeration equipment to solve the problems mentioned above. Utility Model Content

[0007] The purpose of this invention is to provide a pressure intelligent early warning control device for refrigeration equipment. High-pressure gas pushes the extrusion block upward and triggers the control switch, activating the buzzer alarm to emit both light and sound alarms. Furthermore, by rotating the knob and utilizing the threaded engagement of the adjusting screw and nut, the pressing or releasing state of the pressure plate on the compression spring can be flexibly adjusted, thereby solving the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a pressure intelligent early warning control device for refrigeration equipment, comprising a main body, wherein an early warning mechanism is fixedly installed on the top of the main body;

[0009] The main structure includes a device body with a connection port at its bottom. An installation groove is formed on the inner wall of the device body, and a corrugated pipe is fixedly connected to the bottom of the inner wall of the installation groove. Two sliding grooves are formed on the inner wall of the device body, and a sliding plate is slidably embedded between the inner walls of the two sliding grooves. The top of the corrugated pipe is fixedly connected to the bottom of the sliding plate. A compression spring is fixedly connected to the top of the sliding plate, and a pressure plate is fixedly connected to the top of the compression spring. A nut is fixedly connected to the top of the device body, and an adjusting screw is threaded onto the inner wall of the nut. A knob is fixedly connected to the top of the adjusting screw, and a bearing is fixedly fitted onto the outer wall of the adjusting screw. The outer wall of the bearing is fixedly inserted into the pressure plate. A lifting frame is fixedly connected to the top of the sliding plate, and the outer wall of the lifting frame is movably inserted into the device body. A pressing block is fixedly connected to the top of the lifting frame.

[0010] Preferably, the warning mechanism includes a fixed frame, the top of which has two embedding slots, and the inner surface of each of the two embedding slots is movably fitted with an embedding block.

[0011] Preferably, a buzzer alarm is fixedly connected between the tops of the two embedded blocks, and a control switch is provided at the bottom of the buzzer alarm.

[0012] Preferably, a limiting groove is provided on one side of the outer wall of each of the two embedded blocks, and a limiting block is movably inserted into the inner surface of each of the two limiting grooves.

[0017] 1. In this utility model, through the cooperation of the main mechanism and the early warning mechanism, high-pressure gas pushes the extrusion block upward and triggers the control switch, activating the buzzer alarm to emit a dual alarm of light and sound.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Please see Figures 1-6 This utility model provides a pressure intelligent early warning control device for refrigeration equipment, including a main body 1, and an early warning mechanism 2 installed on the top of the main body 1;

[0029] The main body 1 includes a device body 101. A connection port 102 is provided at the bottom of the device body 101. An installation groove 103 is formed on the inner surface of the device body 101. A corrugated pipe 104 is fixedly connected to the bottom of the inner wall of the installation groove 103. Two sliding grooves 105 are formed on the inner surface of the device body 101. A sliding plate 106 is slidably embedded between the inner surfaces of the two sliding grooves 105. The top of the corrugated pipe 104 is fixedly connected to the bottom of the sliding plate 106. A compression spring 107 is fixedly connected to the top of the sliding plate 106. The top of the compression spring 107 is fixedly connected to... There is a pressure plate 108. A nut 109 is fixedly connected to the top of the main body 101 of the device. An adjusting screw 110 is threadedly connected to the inner surface of the nut 109. A knob 111 is fixedly connected to the top of the adjusting screw 110. A bearing 112 is fixedly sleeved on the outer surface of the adjusting screw 110. The outer surface of the bearing 112 is fixedly inserted into the inside of the pressure plate 108. A lifting frame 113 is fixedly connected to the top of the slide plate 106. The outer surface of the lifting frame 113 is movably inserted into the inside of the main body 101 of the device. A pressing block 114 is fixedly connected to the top of the lifting frame 113.

[0030] like Figure 5 and Figure 6 As shown: The warning mechanism 2 includes a fixing frame 201. The top of the fixing frame 201 has two embedding slots 202. The inner surface of each embedding slot 202 is movably fitted with an embedding block 203. By presetting the above components, when the two embedding blocks 203 are accurately inserted into the corresponding embedding slots 202, this process can achieve the initial fixation of the buzzer alarm 204 and ensure that the buzzer alarm 204 can maintain the correct installation position and posture during the subsequent reinforcement process.

[0031] like Figure 5 and Figure 6 As shown: A buzzer alarm 204 is fixedly connected between the tops of the two embedded blocks 203. A control switch 205 is provided at the bottom of the buzzer alarm 204. By presetting the above components, when the control switch 205 is pressed, the buzzer alarm 204 can be activated and emit an alarm sound, thereby quickly attracting the attention of the staff.

[0032] like Figure 5 and Figure 6As shown: Each of the two embedded blocks 203 has a limiting groove 206 on one side of its outer wall, and a limiting block 207 is movably inserted into the inner surface of each of the two limiting grooves 206. By presetting the above components, the two limiting blocks 207 are inserted into the corresponding limiting grooves 206, so that the two embedded blocks 203 are in a fixed state, thereby making the buzzer alarm 204 more stable.

[0033] like Figure 5 and Figure 6 As shown: A pull plate 209 is fixedly connected between the outer walls of the two limit blocks 207. By presetting the above components, the pull plate 209 can drive the two limit blocks 207 to move outward and move out of the corresponding limit groove 206, so that the buzzer alarm 204 can be easily disassembled.

[0034] like Figure 5 and Figure 6 As shown: Two return springs 210 are fixedly connected to one side of the outer wall of the pull plate 209. By pre-setting the above components, the two return springs 210 can provide an inward pulling force for the pull plate 209, preventing the pull plate 209 from being displaced due to external interference during use.

[0035] like Figure 1 As shown: The top of the device body 101 is fixedly connected to the bottom of the fixing frame 201. By pre-setting the above components, the device body 101 and the buzzer alarm 204 can form an integral structure, so that the squeezing block 114 is located at the bottom of the control switch 205. When the squeezing block 114 moves upward, it can correctly squeeze the control switch 205.

[0036] The usage and working principle of this device are as follows: First, connect the connector 102 to the high-pressure gas pipe of the compressor. When the gas pressure generated by the compressor is too high, this gas will push the slide plate 106 upwards vertically through the bellows 104. The upward movement of the slide plate 106 will further compress the compression spring 107, causing it to undergo elastic deformation and store energy. Simultaneously, the rise of the slide plate 106 will also drive the lifting frame 113 and the compression block 114 upwards together. When the compression block 114 rises to the preset position... The pressing block 114 precisely presses against the control switch 205 at the bottom of the buzzer alarm 204, triggering the buzzer alarm 204 to emit a loud alarm sound and a conspicuous alarm light. This dual visual and auditory alert can quickly attract the attention of staff so that they can take timely countermeasures. Furthermore, by rotating the knob 111, the adjusting screw 110 can be rotated within the nut 109. Because the inner wall of the nut 109 and the outer wall of the adjusting screw 110 are connected by threads, the rotation of the adjusting screw 110... This causes the pressure plate 108 to move vertically up and down. The movement of the pressure plate 108 further compresses or releases the compression spring 107, thereby adjusting the elastic force of the compression spring 107. In this way, a specific pressure threshold can be set. Only when the gas pressure reaches or exceeds this threshold will the compression block 114 press the control switch 205 to generate an alarm. When maintaining or replacing the buzzer alarm 204, simply pull the pull plate 209. The pull plate 209 will drive the two limit blocks 207 to move outward, causing the two limit blocks 207 to move outward. 07 is removed from the corresponding limiting groove 206, thereby releasing the fixing state of the embedded block 203. At this time, the buzzer alarm 204 can be easily removed for maintenance. At the same time, the movement of the pull plate 209 will stretch the two return springs 210, causing them to undergo elastic deformation and store energy. When the buzzer alarm 204 is reinstalled after maintenance, the elastic restoring force of the two return springs 210 can be used to push the limiting block 207 to quickly snap into the corresponding limiting groove 206, thereby realizing the quick installation and fixing of the buzzer alarm 204.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
