Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment

[0025] Please refer to Figures 1 to 5 , which is an embodiment of the present invention. This embodiment provides a technical solution: an explosion-proof alarm electric hydraulic pump station that can be remotely controlled, including

[0026] the top plate 2 on the top surface of the fuel tank 1, the explosion-proof motor 4, the alarm 6 and the explosion-proof control valve 7 installed on the top of the top plate 2. An explosion-proof electric control box 3 is also provided on the left side of the fuel tank 1. The explosion-proof electric control box 3 is used to receive remote control signals and control the operation of the entire hydraulic pump station. The explosion-proof motor 4 is controlled by the explosion-proof electric control box 3 and is used to drive the oil pump in the fuel tank 1 to operate. The explosion-proof control valve 7 is used to control and adjust the pressure, flow rate and direction of the hydraulic system. The alarm 6 automatically alarms when the system detects a danger signal;

[0027] And a remote control system for realizing remote monitoring and control functions, including a remote terminal unit, a programmable logic controller, a monitoring and data acquisition module, a remote access module and a communication module. The remote access module and the communication module are used to ensure smooth communication between the remote control system and the hydraulic pump station. The remote terminal unit and the programmable logic controller are used to collect data of each sensor, execute control commands, and send data to the remote control system through a communication network. The monitoring and data acquisition module includes multiple acquisition sensors and an alarm module. The multiple acquisition sensors are used to acquire multiple operating parameters of the hydraulic pump station, and the alarm module is connected to the alarm 6;

[0028] During actual use, when the remote control system issues a start command, the explosion-proof electric control box 3 receives the command and controls the explosion-proof motor 4 to start, driving the oil pump in the fuel tank 1 to rotate. The oil pump inputs the hydraulic oil in the fuel tank 1 into the explosion-proof control valve 7 through the oil circuit system. After being adjusted by the explosion-proof control valve 7, it is sent to the external hydraulic cylinder. The external hydraulic cylinder converts hydraulic energy into mechanical energy to drive the external working mechanism to complete various actions. During the working process, if the system detects dangerous signals such as high pressure and excessive concentration of flammable and explosive gases, the alarm 6 will automatically alarm. The remote control system can monitor the working state of the hydraulic pump station in real time and issue control commands as needed to realize remote monitoring and control functions;

[0029] A plurality of protective fences 5 are slidably arranged on the top of the top plate 2, and an adjusting structure is arranged between the protective fence 5 and the top plate 2, which is convenient for subsequent sliding adjustment of the position of the protective fence 5 and can also facilitate the subsequent quick disassembly of the protective fence 5, removing the blockage of the explosion-proof motor 4, the alarm 6 and the explosion-proof control valve 7, and facilitating the subsequent maintenance of these components.

[0030] In this embodiment, preferably, T-shaped sliding seats 51 are welded and fixed at both bottom ends of the protective fence 5, and two T-shaped sliding grooves 21 corresponding to the T-shaped sliding seats 51 are opened on the top surface of the top plate 2. The T-shaped sliding seats 51 are slidably located in the T-shaped sliding grooves 21.

[0031] In this embodiment, preferably, the adjusting structure includes a side dial block 81 slidably arranged on the outer surface of the protective fence 5, a limit clamping rod 87 welded and fixed to the bottom surface of the side dial block 81, and a plurality of limit clamping holes 82 corresponding to the limit clamping rod 87 opened on the surface of the top plate 2. The limit clamping rod 87 is inserted into one of the limit clamping holes 82 to realize the stable limit of the protective fence 5 during daily use. When it is necessary to release the limit of the protective fence 5 to realize the sliding or removal of the protective fence 5 later, only need to lift the side dial block 81 to make the limit clamping rod 87 move out of the limit clamping hole 82, and the limit of the protective fence 5 can be quickly released. At this time, the protective fence 5 can be slid back and forth to realize sliding adjustment or sliding removal.

[0032] In this embodiment, preferably, the adjusting structure further includes a side sliding seat 83 movably installed on the inner surface of the protective fence 5, a strip-shaped slideway 89 penetrating through the surface of the protective fence 5, and a connecting slider 88 movably arranged inside the strip-shaped slideway 89. One end of the connecting slider 88 extends to the outside of the protective fence 5 and is fixed to the side dial block 81, and the other end of the connecting slider 88 extends to the inside of the protective fence 5 and is fixed to the side sliding seat 83, so that the side dial block 81 can drive the side sliding seat 83 to move up and down together.

[0033] In this embodiment, preferably, the adjusting structure further includes a side support plate 85 welded and fixed on the inner surface of the protective fence 5 and above the side sliding seat 83, and a guide rod 86 fixed on the top of the side sliding seat 83. The top end of the guide rod 86 penetrates through the top of the side support plate 85, which can play a role of guiding and supporting when the side sliding seat 83 moves up and down. A spring 84 is sleeved on the surface of the guide rod 86 between the side support plate 85 and the side sliding seat 83. Under the pushing of the spring 84, it can ensure that the limit latch 87 is stably inserted into the limit hole 82 during daily use, ensuring the limit stability of the protective fence 5. Subsequently, when the operator lifts the side dial block 81, the connecting slider 88 will drive the side sliding seat 83 to move up and gradually compress the spring 84.

[0034] In this embodiment, preferably, a circular rod hole for the guide rod 86 to penetrate through is formed through the surface of the side support plate 85.

[0035] Although the embodiments of the present invention have been shown and described (see the above detailed description), for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
