Description

Technical Field

[0001] The invention relates to the technical field of cable sealing, and in particular to a cable sealing device suitable for a transmitter. Background Art

[0002] The existing transmitter cable sealing devices mainly have the following problems: the sealing structure is simple, the sealing effect is poor, the sealing ring can only play a simple physical isolation role, and cannot effectively prevent internal corrosion of the cable and intrusion from the outside environment; the sealing connection method is traditional, relying on bolt connection, which is prone to loose connection and water leakage; the sealing performance cannot meet the working requirements of harsh environments, such as high temperature, high humidity, salt spray environment, etc.

[0003] Most existing transmitter cable sealing devices are simple structures, relying only on rubber waterproof rubber rings or sealing gaskets for sealing. The sealing effect of this type of device is limited, and it is easy to age in harsh environments. There is a high risk of water leakage and dust leakage, and the sealing strength cannot be dynamically controlled, making it difficult to meet the sealing requirements of different occasions. In recent years, some improved sealing devices have attempted to use multi-layer sealing structures or multi-point sealing methods to improve sealing performance, such as using mechanical seals or threaded connection structures to enhance the stability and reliability of the seal. However, these devices have complex structures, cumbersome installation, high costs, and the sealing effect still has certain limitations. In addition, it is difficult for existing transmitter cable sealing devices to actively adjust in combination with changes in ambient temperature, which makes their sealing performance easily affected by the external ambient temperature and shortens their service life.

[0004] To this end, we propose a cable sealing device suitable for a transmitter. Summary of the invention

An air pump is fixedly provided on the top of the upper sealing frame, and the air outlet end of the air pump is connected to the interior of the air guide hole.

[0010] Furthermore, a lower heat exchange channel is disposed inside the lower sealing frame, an upper heat exchange channel is disposed inside the upper sealing frame, and the interior of the lower heat exchange channel is communicated with the interior of the upper heat exchange channel.

[0013] Furthermore, the sealing method of the cable sealing device applicable to the transmitter comprises the following steps:

[0014] Step 1: When sealing and connecting the cable of the transmitter, the connection protrusion at the bottom of the upper sealing frame and the connection groove at the top of the lower sealing frame are matched and connected, and then the four connection screws around the inside of the fixing frame are used to thread the inside of the upper sealing frame and the lower sealing frame respectively. By opening four connection threaded holes at the cable connection of the transmitter, the sealing rings on the back of the upper sealing frame and the lower sealing frame are matched and connected with the sealing groove on one side of the transmitter, and finally one end of the four connection screws is connected to the four connection threaded holes to complete the fixed connection of the upper sealing frame and the lower sealing frame on one side of the transmitter;

[0015] Step 2: When sealing the cable of the transmitter, the specifications and sizes of the first sealing gasket and the second sealing cover gasket are selected according to the diameter of the cable. The first sealing block is first threadedly installed on the back of the sealing hole, and then the first sealing gasket is placed on the back of the first sealing block. Then, the second sealing block and the limit block are threadedly arranged on the front side of the sealing hole. At the same time, a second sealing gasket is arranged between the second sealing block and the limit block. The pressure of the first sealing gasket is controlled by the first sealing block according to the sealing strength of the cable. The connection length of one end of the four connecting screws and the four connecting threaded holes on one side of the transmitter is controlled by rotating the four connecting screws, and the pressure control of the first sealing block on the front of the first sealing gasket is controlled, so as to ensure the sealing connection effect on the back of the transmitter cable surface through the first sealing gasket.

[0016] Step 3: When sealing the surface of the transmitter cable, the cable is passed through the inside of the sealing sleeve, and the front and rear sides of the cable surface are sealed and connected with the two second sealing rings on the front and rear sides of the sealing sleeve. Then, air is introduced into the sealing groove through an air pump, and the two movable pressure plates are pushed on the surface of the cable by air. The two sealing fillers inside the sealing groove are squeezed by the front and rear two movable pressure plates. The cable surface is sealed twice by the front and rear two sealing fillers inside the sealing groove, and the air pressure inside the sealing groove is dynamically adjusted by the air pump.

[0017] Step 4. When the transmitter cable sealing device is used daily, the heat exchange of the sealing components inside the upper sealing frame and the lower sealing frame is controlled according to the external ambient temperature. When the external ambient temperature is low, the air inside the lower heat exchange flow channel and the upper heat exchange flow channel is heated by the resistance heating wire, and the air inside the lower heat exchange flow channel and the upper heat exchange flow channel is circulated and controlled by the circulating fan, and the sealing components inside the upper sealing frame and the lower sealing frame are heated by the hot air; when the external ambient temperature is high, the air inside the lower heat exchange flow channel and the upper heat exchange flow channel is cooled by the semiconductor refrigeration sheet, and the air inside the lower heat exchange flow channel and the upper heat exchange flow channel is circulated and controlled by the circulating fan, and the sealing components inside the upper sealing frame and the lower sealing frame are cooled by the cold air.

[0018] The beneficial effects achieved by the present invention using the above structure are as follows:

[0019] 1. In this device, the upper sealing frame and the lower sealing frame are matched with the connecting protrusions and connecting grooves, and are fixedly connected with the connecting screws on the fixing frame, so as to effectively ensure the sealing effect of the cable at the transmitter. The upper sealing frame and the lower sealing frame are both provided with sealing holes. The first sealing block and the second sealing block cooperate with the first sealing gasket and the second sealing cover gasket to adjust the pressure according to the cable diameter to achieve double sealing on the cable surface; in addition, a sealing sleeve is provided in the device, and the sealing pressure is dynamically regulated by the sealing filler and the movable pressure plate in cooperation with the air pump to ensure the reliability of the cable surface sealing. The built-in heat exchange flow channel and circulating fan system can automatically adjust the internal temperature according to the ambient temperature. The resistance heating wire and the semiconductor refrigeration sheet cooperate with the circulating fan to effectively extend the service life of the sealing components, improve the overall sealing performance and weather resistance of the device, and ensure the long-term sealing stability of the transmitter cable connection.

[0020] 2. When sealing the cable of the transmitter, the connection protrusion at the bottom of the upper sealing frame is matched with the connection groove at the top of the lower sealing frame, and then the four connecting screws around the inside of the fixing frame are used to thread the inside of the upper sealing frame and the lower sealing frame respectively. By opening four connecting threaded holes at the cable connection of the transmitter, the sealing rings on the back of the upper sealing frame and the lower sealing frame are matched with the sealing groove on one side of the transmitter, and finally one end of the four connecting screws is connected to the four connecting threaded holes to complete the fixed connection of the upper sealing frame and the lower sealing frame on one side of the transmitter, and the upper sealing frame and the lower sealing frame are used to seal the cable.

[0021] 3. When sealing the surface of the transmitter cable, pass the cable through the inside of the sealing sleeve, and seal the front and rear sides of the cable surface with the two second sealing rings on the front and rear sides of the sealing sleeve. Then, introduce air into the sealing groove through an air pump, use the air to push the two movable pressure plates on the surface of the cable, use the front and rear two movable pressure plates to squeeze the two sealing fillers inside the sealing groove, and perform two sealing treatments on the cable surface through the front and rear sealing fillers inside the sealing groove. Dynamically adjust the air pressure inside the sealing groove through the air pump, so as to achieve dynamic control of the sealing pressure of the front and rear sealing fillers on the cable surface.

[0022] 4. When the transmitter cable sealing device is used daily, the heat exchange of the sealing components inside the upper sealing frame and the lower sealing frame is controlled according to the external ambient temperature. When the external ambient temperature is low, the air inside the lower heat exchange flow channel and the upper heat exchange flow channel is heated by the resistance heating wire, and the air inside the lower heat exchange flow channel and the upper heat exchange flow channel is circulated and controlled by the circulating fan, and the sealing components inside the upper sealing frame and the lower sealing frame are heated by the hot air; when the external ambient temperature is high, the air inside the lower heat exchange flow channel and the upper heat exchange flow channel is cooled by the semiconductor refrigeration sheet, and the air inside the lower heat exchange flow channel and the upper heat exchange flow channel is circulated and controlled by the circulating fan, and the sealing components inside the upper sealing frame and the lower sealing frame are cooled by the cold air; by dynamically adjusting the temperature of the sealing components inside the sealing device, the service life of the first sealing ring and the second sealing ring inside the sealing device is effectively extended, and the weather resistance of the first sealing ring and the second sealing ring can be improved to a great extent, thereby ensuring the sealing effect of the sealing device on the transmitter cable connection.
