DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3The utility model provides a technical solution: an automatic refueling mechanism for a seismic meter, comprising a cylindrical shell 1, a refueling assembly 200 for automatic refueling is installed on the inner side of the cylindrical shell 1, a convenient assembly 300 for improving the convenience of use is installed on the outer side of the cylindrical shell 1, and a control mechanism for control is installed on the outer side of the cylindrical shell 1; through the coordinated use of the refueling assembly 200 on the inner side of the cylindrical shell 1 and the convenient assembly 300 on the outer side, hand-held refueling is convenient, and by redividing the refueling structure layout and reducing the steps of refueling operation, the mechanism can be conveniently controlled by the staff by hand, and the oil volume can be replenished in real time, so that the refueling work can be carried out normally, thereby effectively improving the practicality of the automatic refueling mechanism of the seismic meter.

[0024] In this embodiment, the convenience component 300 is a structure for providing convenience for refueling and convenient carrying.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, the convenience component 300 includes a handle 301 fixedly mounted on the top of the cylindrical shell 1, a shoulder strap 302 fixedly mounted on the top of the cylindrical shell 1, a fixed frame 303 fixedly mounted on the front of the cylindrical shell 1, an oil storage tank 304 fixedly mounted on the inner side of the fixed frame 303, an oil inlet valve pipe 305 fixedly mounted on the top of the oil storage tank 304 for conveying oil, a second one-way valve 306 fixedly mounted on the outside of the oil inlet valve pipe 305, an air valve 307 fixedly mounted on the top of the oil storage tank 304 for balancing the air pressure, and a delivery pipe 308 fixed on the top of the oil storage tank 304.

[0026] It should be noted that the top end of the delivery pipe 308 is connected with a rubber plug for sealing and blocking dust, which can block dust and seal the top end of the delivery pipe 308 , and the oil can be stored in the oil storage tank 304 through the delivery pipe 308 .

[0027] In addition, under the action of the air valve 307, the internal and external air pressures of the oil storage tank 304 can be kept balanced when oil is discharged or received, thereby facilitating the entry and exit of the oil. The second one-way valve 306 can limit the oil delivery path, so that the oil inside the oil inlet valve pipe 305 can only be output to the outside through the oil storage tank 304.

[0028] In this embodiment, the refueling assembly 200 is a structure for automatically performing refueling at a constant speed.

[0029] like Figure 1 and Figure 2As shown, the refueling assembly 200 includes a linear drive mechanism 201 fixedly mounted on the inner side of the cylindrical shell 1, a cylinder 202 fixedly mounted on the inner side of the cylindrical shell 1, a piston rod 203 slidably connected to the inner side of the cylinder 202 and with its end located on the right side of the cylinder 202, an oil outlet valve 204 fixedly mounted on the left side of the cylinder 202, a first one-way valve 205 fixedly mounted on the outer side of the oil outlet valve 204, a docking box 206 fixed to the bottom of the cylindrical shell 1, a connecting plate 207 fixedly mounted on the outer side of the output end of the linear drive mechanism 201, a laser sensor 208 fixedly mounted on the left side of the connecting plate 207, a small main controller 209 fixedly mounted on the inner side of the docking box 206, a laser receiving reflection plate 210 fixedly mounted on the inner side of the docking box 206 and located on the right side of the small main controller 209, a positioning rod 211 fixedly mounted on the inner side of the docking box 206, and a power supply mechanism 212 fixedly mounted on the inner side of the docking box 206.

[0030] It should be noted that the first one-way valve 205 can limit the oil flowing inside the oil outlet valve 204, so that the oil can only be output outward through the oil cylinder 202. The linear drive mechanism 201 can be a linear drive device with a smooth stroke such as a cylinder or an electric push rod. The right side of the oil cylinder 202 and the outer side of the piston rod 203 are sealed and slidably connected, and can be connected by a buffer seal ring, a piston seal ring and other seals that are suitable for sliding sealing. The sealing principle is the same as the sealing principle of the hydraulic cylinder, which is an existing public technology, so it will not be elaborated in detail.

[0031] At the same time, the left side of the cylindrical shell 1 is open, and the oil cylinder 202 is located on the left side of the inner side of the cylindrical shell 1, so that the oil cylinder 202 can normally refuel through the oil outlet valve 204, and the right end of the piston rod 203 is fixedly installed on the output end of the linear drive mechanism 201, so that the linear drive mechanism 201 can push the piston rod 203 to move.

[0032] In addition, a connecting hole is provided at the bottom of the cylindrical shell 1, which is connected to the interior of the docking box 206 and for the connecting plate 207 to slide. A fixing rod passing through the left side of the connecting plate 207 is fixedly connected to the inner side of the connecting hole. The right end of the positioning rod 211 passes through the left side of the connecting plate 207, so that the connecting plate 207 can slide stably on the inner side of the connecting hole under the cooperation between the fixing rod and the positioning rod 211.

[0033] In addition, the position of the laser sensor 208 corresponds to the laser receiving reflector plate 210, so that the laser beam emitted by the laser sensor 208 can be received by the laser receiving reflector plate 210 and reflected back to the laser sensor 208, thereby calculating the current distance, and the travel distance of the linear drive mechanism 201 can be monitored in real time. The end of the oil inlet valve pipe 305 passes through the front side of the cylindrical shell 1 and is fixedly connected to the front side of the cylinder 202, and the interior of the oil inlet valve pipe 305 is connected to the interior of the cylinder 202, so that The oil stored in the oil storage tank 304 can be transported to the interior of the oil cylinder 202 through the oil inlet valve pipe 305. Specifically, when refueling, the oil in the oil cylinder 202 enters the interior of the oil outlet valve 204 through the first one-way valve 205 and is output to the outside, while the second one-way valve 306 is in a closed state. When returning after refueling, the first one-way valve 205 is in a closed state, while the second one-way valve 306 is opened, so that the oil in the oil storage tank 304 is transported to the interior of the oil cylinder 202 through the oil inlet valve pipe 305 for filling.

[0034] It should also be noted that the control mechanism includes a control button panel 401 fixedly mounted on the top of the cylindrical shell 1, and a display panel 402 fixedly mounted on the front of the cylindrical shell 1. The linear drive mechanism 201, the laser sensor 208, the display panel 402 and the control button panel 401 are all electrically connected to the small main controller 209. The linear drive mechanism 201, the laser sensor 208, the display panel 402, the control button panel 401 and the small main controller 209 are all electrically connected to the power supply mechanism 212, so that the small main controller 209 can control the electronic device, and the power supply mechanism 212 can provide power support. The electrical connection technology is an existing public technology. The control method of the small main controller 209 can be realized after simple programming by those skilled in the art, and they are all existing public control technologies, so there is no need to elaborate on them.

[0035] The working principle of the above embodiment is:

[0036] When refueling, hold the handle 301, connect the oil outlet valve 204 to the oil inlet port of the seismic meter, adjust the refueling value on the display panel 402 through the control button panel 401, start the linear drive mechanism 201, push the oil inside the oil cylinder 202 to the inside of the oil outlet valve 204 through the piston rod 203 and make it flow to the inside of the seismic meter to perform the refueling work, and with the cooperation between the laser sensor 208 and the laser receiving reflection plate 210, the travel distance of the linear drive mechanism 201 can be monitored in real time, so that the travel distance of the linear drive mechanism 201 can be matched with the preset value, so that the error of the oil output is minimized. After refueling is completed, the linear drive mechanism 201 returns, so that the inside of the oil cylinder 202 is in a negative pressure state, and the oil stored in the oil tank 304 is transported to the inside of the oil cylinder 202 through the oil inlet valve pipe 305 for filling, and the refueling of the seismic meter can be completed.

[0037] Compared with the prior art, the automatic refueling mechanism of the seismic meter facilitates hand-held refueling through the coordinated use of the refueling component 200 on the inner side of the cylindrical shell 1 and the convenient component 300 on the outer side. By redividing the refueling structure layout and reducing the steps of refueling operation, the mechanism can be conveniently controlled by the staff by hand, and the oil can be replenished in real time, so that the refueling work can be carried out normally, thereby effectively improving the practicality of the automatic refueling mechanism of the seismic meter and solving the problem that the existing automatic refueling machine of the seismic meter is inconvenient for hand-held refueling.

[0038] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0039] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
