[0001] This utility model belongs to the field of pressure protection sensor technology, and specifically relates to a pressure protection structure for a hydraulic pump station. Background Technology
[0002] A hydraulic pump station is a pump station that provides hydraulic power in a hydraulic system. When a hydraulic pump station is in use, its hydraulic pressure needs to be monitored and protected. This is usually done by installing a pressure protection sensor. The existing pressure protection sensor is a device installed on the hydraulic pump station for the hydraulic system to protect its pressure. It is convenient to convert the monitored pressure signal into an electrical signal for monitoring and protection after installation.
[0003] Existing pressure protection sensors are installed on hydraulic pump stations for hydraulic protection. They are directly fixed to the internal thread at the installation location by rotating the external thread of the sensor at the bottom. However, this method is not easy to reinforce after installation. When the hydraulic pump station is in use, it is prone to vibration, and prolonged vibration can cause loosening and instability. This makes the installation and use of the pressure protection sensor unstable, affecting the reinforcement and stability of the pressure protection sensor when used on the hydraulic pump station's hydraulic system. Therefore, this utility model proposes a pressure protection structure for hydraulic pump stations. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic pump station pressure protection structure, including a pressure protection sensor. The pressure protection sensor includes a main sensor body, a connecting wire installed at the top of one side of the main sensor body, a connecting end provided at the bottom of the main sensor body, and an external threaded head at the bottom of the connecting end.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a hydraulic pump station pressure protection structure, including a pressure protection sensor 100. The pressure protection sensor 100 includes a main sensor body 101, a connecting wire 102 installed at the top of one side of the main sensor body 101, a connecting end 103 provided at the bottom of the main sensor body 101, and an external threaded head 104 provided at the bottom of the connecting end 103. The pressure protection sensor 100 is also provided with:
[0024] The reinforcement fixing mechanism includes a reinforcement mounting component located at the top edge of the external threaded head 104. The top of the reinforcement mounting component is provided with an adjustment component. After the pressure protection sensor 100 is fixedly installed through the external threaded head 104, the reinforcement fixing mechanism reinforces the external threaded head 104 for installation. This facilitates the reinforcement fixing of the pressure protection sensor 100 after installation, ensuring stable installation and pressure protection even when the hydraulic pump station vibrates during long-term operation.
[0025] To facilitate further reinforcement and fixation of the external threaded head 104 after rotation using the reinforcement mounting assembly, in this embodiment, preferably, the reinforcement mounting assembly includes a movement control groove 1041 formed at the top edge of the external threaded head 104. A connecting groove 1044 is formed on one side of the bottom end of the movement control groove 1041. A reinforcement clamp 1045 is provided inside the connecting groove 1044. After the external threaded head 104 is installed, the reinforcement clamp 1045 can move inside the connecting groove 1044 until the reinforcement clamp 1045 is pressed tightly against the edge of the internal threaded hole at the installation location for reinforcement and fixation.
[0026] To facilitate the adjustment and reinforcement of the reinforcing clamp 1045 through the adjustment component, in this embodiment, preferably, the adjustment component includes a movable column 1042 disposed on one side inside the movable control groove 1041. A connecting rod 1043 is installed at the connection between the lower surface of the movable column 1042 and the top end of the reinforcing clamp 1045. A threaded rod 1047 is installed inside the movable control groove 1041 on the surface of the movable column 1042. The end of the threaded rod 1047 extends through to the surface of the external thread head 104. An adjusting nut 1046 is provided at the end of the threaded rod 1047 on the surface of the external thread head 104. The adjusting nut 1046 can be rotated in place on the outer surface of the threaded rod 1047 to adjust and drive the threaded rod 1047 to move. When the threaded rod 1047 moves, it drives the movable column 1042 and the connecting rod 1043 to move until the reinforcing clamp 1045 is moved, clamped, and fixedly installed.
[0027] The enhanced sealing mechanism includes a closed mounting assembly disposed at the bottom end and edge of the external threaded head 104. The closed mounting assembly is internally provided with an enhanced sealing assembly, which can enhance the sealing of the pressure protection sensor 100 when the bottom end of the external threaded head 104 is rotated and fixed to the bottom end of the internal threaded hole at the mounting location after the pressure protection sensor 100 is installed.
[0028] To facilitate the installation of the edge sealing gasket 1049 and the bottom sealing gasket 1040 through the closed installation assembly and to enhance the sealing installation, in this embodiment, preferably, the closed installation assembly includes a mounting groove 1048 formed at the bottom edge of the external threaded head 104. The mounting groove 1048 and the external threaded head 104 are an integral structure, so that when the edge sealing gasket 1049 is closed inside the mounting groove 1048, the bottom end of the bottom sealing gasket 1040 is closed on the bottom surface of the external threaded head 104, which facilitates installation, sealing and fixing.
[0029] To facilitate a reinforced sealing installation between the bottom end of the external threaded head 104 and the bottom end of the internal threaded hole at the mounting location, in this embodiment, preferably, the reinforced sealing assembly includes an edge sealing gasket 1049 disposed inside the mounting groove 1048. The bottom end of the edge sealing gasket 1049 is integrally provided with a bottom sealing gasket 1040 on the end surface of the external threaded head 104. When the bottom end of the external threaded head 104 is embedded into the inner bottom end of the internal threaded hole, the bottom sealing gasket 1040 presses and seals the bottom surface of the external threaded head 104, while the edge sealing gasket 1049 presses and seals the bottom edge of the external threaded head 104, facilitating a double-reinforced sealing installation and accurate pressure monitoring for protection.
[0030] The working principle and usage process of this utility model: Before use, this hydraulic pump station pressure protection structure is first installed. The main sensor body 101 can be closed at the installation location of the hydraulic system on the hydraulic pump station, and the external thread head 104 is rotated and fixed in the internal thread hole of the installation location, thereby fixing the pressure protection sensor 100. After installation, the connecting wire 102 is connected to the power supply to install and use the pressure protection sensor 100. In use, it is convenient to convert the hydraulic signal of the hydraulic pump station into an electrical signal through the pressure protection sensor 100 for direct display, thereby monitoring and protecting the pressure of the hydraulic system of the hydraulic pump station.
[0031] Then, after the pressure protection sensor 100 is fixedly installed by rotating the external thread head 104, the wrench is once again engaged on the outer surface of the adjusting nut 1046, and the adjusting nut 1046 is rotated in place on the outer surface of the threaded rod 1047, causing the threaded rod 1047 to move. When the threaded rod 1047 moves, it causes the moving column 1042 and the connecting rod 1043 to move inside the moving control groove 1041. At the same time, the connecting rod 1043 causes the reinforcing clamp 1045 to slide inside the connecting groove 1044 until the end of the reinforcing clamp 1045 is tightly pressed and engaged on the inner surface of the internal threaded hole at the installation location for reinforcement and installation. This makes it easier to strengthen the fixed installation of the pressure protection sensor 100 after installation, and it can still be stably installed and used for pressure protection when the hydraulic pump station vibrates during long-term operation. This improves the reinforcement and stability of the pressure protection sensor 100 when it is installed in the hydraulic system of the hydraulic pump station for pressure protection.
[0032] Finally, before the pressure protection sensor 100 is installed and used, the edge sealing gasket 1049 is closed inside the mounting groove 1048. At the same time as closing the edge sealing gasket 1049, the bottom sealing gasket 1040 is closed at the bottom end of the external thread head 104 and contacts the bottom surface of the external thread head 104. Therefore, when the pressure protection sensor 100 is rotated and fixed to the bottom end of the internal thread hole at the installation location through the external thread head 104, it is convenient to seal the bottom end of the external thread head 104 with the bottom end of the internal thread hole through the bottom sealing gasket 1040. At the same time, the edge sealing gasket 1049 deforms and presses tightly against the bottom edge of the internal thread hole for sealing and fixing. This facilitates double-strength sealing for accurate pressure protection and improves the sealing performance of the pressure protection sensor 100 installed in the hydraulic system of the hydraulic pump station.
