[0001] This utility model relates to the field of seismic exploration instruments and equipment technology, and in particular to a seismograph hammer switch device. Background Technology

[0002] In order to reach a certain exploration depth, seismic exploration (such as surface wave exploration) requires the use of falling objects to impact the ground or the use of large mechanical devices to impact the ground to generate seismic waves and trigger recording. This excitation method can be achieved by placing a hammer switch on the ground, placing an iron plate above the hammer switch, and letting a heavy object fall onto the iron plate or using a large mechanical device to strike the iron plate, thereby triggering recording. However, during operation, the wires of the hammer switch are easily broken, which may cause serious damage to the hammer switch, making it difficult to reuse the device. Utility Model Content

[0028] Please see Figures 1-5 This application provides a seismograph hammer-striking switch device, including a protection component 100 and a switch component 200. The protection component 100 includes a force-bearing member 110 and a support leg 120. The support leg 120 is disposed on one side of the bottom of the force-bearing member 110, so that a placement space 111 is formed between the force-bearing member 110 and the ground 20. The switch component 200 includes two opposing pole plates 210. One end of the two pole plates 210 is insulated from each other, and an opening is formed between the other ends of the two pole plates 210. The opening is disposed within the placement space 111, and the two pole plates 210 are respectively connected to the positive and negative poles of the seismograph trigger signal line 10. When the force-bearing component 110 is subjected to an impact force, the outrigger 120 can be driven into the ground 20, so that the openings of the two electrode plates 210 are closed, thereby connecting the two electrode plates 210 with the trigger signal line 10.

[0029] The load-bearing component 110 is used to withstand impacts from falling objects and mechanical shocks. In use, the load-bearing component 110 is placed on the ground 20. Since the support leg 120 is located on one side of the bottom of the load-bearing component 110, meaning one side of the load-bearing component 110 contacts the ground 20, and the other support leg 120 supports the load-bearing component 110 between it and the ground 20, an angled gap is formed between the load-bearing component 110 and the ground 20. This angled gap forms the placement space 111. The support leg 120 is slender and rod-shaped, maintaining a stable connection with the load-bearing component 110. Due to the small cross-section of the support leg 120, when the load-bearing component 110 is impacted, the support leg 120 will embed itself into the soil of the ground 20. After use, the load-bearing component 110 can be lifted, and the support leg 120 can be easily pulled out of the soil. Specifically, the load-bearing component 110 can be a roughly rectangular sleeper, which should have sufficient strength, rigidity and impact resistance; there are two outriggers 120, which are spaced apart on one side of the load-bearing component 110.

[0030] The switch assembly 200 includes two opposing electrode plates 210, which are respectively connected to the positive and negative terminals of the seismograph trigger signal line 10. One end of each electrode plate 210 is insulated from the other end, forming an opening between them. Under normal circumstances, the two electrode plates 210 do not contact each other, thus preventing electrical conduction with the trigger signal line 10. Specifically, the two electrode plates 210 possess a certain degree of flexibility and can be made of carbon steel or alloy tool steel. After heat treatment, they achieve high hardness and are not easily worn. The two electrode plates 210 are generally flat, providing good impact resistance, and even with some deformation, they can maintain their naturally open state.

[0031] The opening is located within the placement space 111. When the force-bearing component 110 is subjected to an impact force, the outrigger 120 will penetrate into the ground 20, thereby driving the force-bearing component 110 to move towards the ground 20. Since the two pole plates 210 are located below the force-bearing component 110, the openings of the two pole plates 210 can be closed, that is, the two pole plates 210 will contact each other, so that the positive and negative poles of the trigger signal line 10 are short-circuited, triggering the recording signal, so that the seismograph completes one data recording.

[0032] In the seismograph hammer-striking switch device provided in this application, when the force-bearing component 110 is subjected to impact force, the outrigger 120 can be driven into the ground 20, so that the openings of the two pole plates 210 are closed, thereby connecting the two pole plates 210 with the trigger signal line 10. That is, the force-bearing component 110 is used to withstand the impact of falling objects and mechanical impact, thereby protecting the switch assembly 200 in the placement space 111 from serious damage under impact as much as possible, increasing the number of times the switch device can be reused, and making the switch device more reliable.

[0033] Please see Figure 4 and Figure 5 In some embodiments, the switch assembly 200 further includes a connector (not shown) and a separator 220, both of which are made of insulating material; the separator 220 is disposed between one end of the two plates 210, the connector connects one end of the two plates 210, and the other end of the two plates 210 forms an opening.

[0034] A separator 220 is disposed between one end of the two electrode plates 210, thus insulating and separating one end of the two electrode plates 210 and preventing them from contacting and conducting electricity. A connector connects one end of the two electrode plates 210, thus achieving an insulated connection between the two ends and forming a single unit. Because the separator 220 is provided between one end of the two electrode plates 210, an opening is naturally formed at the other end of each plate. Specifically, the connector can be rope-like to tie one end of the two electrode plates 210 together, achieving the connection. Both the connector and the separator 220 can be made of any insulating material, such as nylon, and there are no limitations on this.

[0035] In some embodiments, the switch assembly 200 further includes a support 230 made of insulating material, which is sandwiched between the two electrode plates 210.

[0036] The expansion member 230 is located on the side of the separator 220 near the opening. Since the expansion member 230 is sandwiched between the two electrode plates 210, the other ends of the two electrode plates 210 can be further prevented from contacting under the restriction of the expansion member 230, so that the other ends of the two electrode plates 210 naturally open, preventing the switching device from being in the triggered state when not in use, causing erroneous triggering of the recording signal.

[0037] Specifically, the support member 230 can be a rod-shaped structure. The support member 230 can be movably clamped between the two pole plates 210, thereby adjusting the distance between the support member 230 and the opening, which in turn adjusts the angle of the opening.

[0038] In some embodiments, the switch assembly 200 further includes two copper wires 240, which are disposed on two electrode plates 210 respectively, and are connected to the positive and negative terminals of the trigger signal line 10 respectively.

[0039] To ensure reliable triggering and prevent incomplete waveform recording due to delays, both electrode plates 210 are wound with copper wires 240. The copper wires 240 can be composed of bundled copper wires; the thin wires do not need to be tightly braided, allowing them to deform under impact or compression, flattening their cross-section without shear failure. To ensure reliable triggering, the winding directions of the copper wires 240 on the two electrode plates 210 can be perpendicular to each other, and the copper wires 240 are also connected to the positive and negative terminals of the seismograph trigger signal line 10, respectively. The copper wires 240 can be easily replaced. If too many copper wires are broken or the wire performance deteriorates, the old copper wires 240 can be removed and replaced with new ones.

[0040] Please see Figure 1 and Figure 2In some embodiments, the switching device further includes an indicator light 300, with two copper wires 240 connected to the two terminals of the indicator light 300 respectively. The indicator light 300 is used to indicate to the user whether the two electrodes 210 are in contact, allowing the user to understand the connection status of the signal line without activating the seismograph. When the two electrodes are in contact, the indicator light 300 illuminates; when the two electrodes are out of contact, the indicator light 300 turns off.

[0041] Please see Figure 1 and Figure 2 In some embodiments, the force-bearing member 110 has a first side and a second side opposite to each other, the support leg 120 is disposed on the second side of the force-bearing member 110 with an opening facing the first side of the force-bearing member 110, and a portion of the switch assembly 200 is disposed outside the placement space 111.

[0042] The opening formed by the two electrode plates 210 is located within the placement space 111, while the remaining portion is located outside the placement space 111. The seismograph trigger signal line 10 is positioned near the second side of the force-bearing component 110. When there is no external force impacting the force-bearing component 110, the opening formed by the two electrode plates 210 naturally opens, the indicator light 300 does not illuminate, and the signal is not triggered. When the force-bearing component 110 is subjected to impact force, the outrigger 120 penetrates into the ground 20, and the force-bearing component 110 also presses down on the two electrode plates 210, causing the opening to close and the two electrode plates 210 to contact. The positive and negative terminals of the seismograph trigger signal line 10 are short-circuited, triggering the recording signal, and the seismograph completes one data recording cycle.

[0043] Please see Figure 6 and Figure 7 In some embodiments, the force-bearing member 110 has a first side and a second side, the support leg 120 is disposed on the second side of the force-bearing member 110 with an opening facing the second side of the force-bearing member 110, and the entire switch assembly 200 is disposed within the placement space 111.

[0044] The opening can also face the second side of the force-receiving component 110, and the entire switch assembly 200 is disposed within the placement space 111. As long as the opening formed by the two electrode plates 210 is located within the placement space 111, the opening can be closed and the two electrode plates 210 can contact each other when the force-receiving component 110 is subjected to an impact force. There are no restrictions on this. Of course, in this case, the seismograph trigger signal line 10 is positioned close to the first side of the force-receiving component 110.

[0045] Please see Figure 5 In some embodiments, the protective component 100 further includes a magnetic element 130 disposed on the bottom surface of the force-bearing component 110, and the magnetic element 130 adsorbs one of the electrode plates 210.

[0046] The magnetic component 130 can be a magnet. The magnetism of the magnetic component 130 should be able to just attract one of the plates 210 near the force-receiving component 110, without attracting the two plates 210 together. The magnetic component 130 can keep the relative position of the switch assembly 200 and the force-receiving component 110 unchanged, thereby facilitating the installation of the switch assembly 200 and the force-receiving component 110 on the ground 20.

[0047] In some embodiments, the first side of the force-bearing member 110 is provided with a wiring groove 112 for the trigger signal line 10 to pass through.

[0048] Since the seismograph trigger signal line 10 is located close to the first side of the force-receiving component 110, and the first side of the force-receiving component 110 is in contact with the ground 20, in order to allow the trigger signal line 10 to enter the placement space 111 to connect with the two electrode plates 210, a wiring groove 112 is provided at the corner of the first side of the force-receiving component 110, through which the trigger signal line 10 can pass.

[0049] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
