DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0031] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0032] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0033] like Figures 1 to 4 As shown, in the first aspect, an embodiment of the present application provides an energy supply mechanism, including: a base 10, a functional component, a thermal battery component 20 and an excitation component 30; the functional component is arranged in the base 10 for alarm; the thermal battery component 20 is arranged in the base 10, and the thermal battery component 20 is electrically connected to the functional component to provide electrical energy to the functional component; the excitation component 30 includes a sensing structure 31 and a triggering structure 32, the sensing structure 31 and the triggering structure 32 have a locking state and a triggering state, when in the triggering state, the sensing structure 31 unlocks the triggering structure 32, and the triggering structure 32 supplies energy to the thermal battery component 20 to activate the thermal battery component 20 to provide electrical energy to the functional component.

[0034] By setting the sensing structure 31 to adapt the trigger condition information, and then activating the thermal battery assembly 20 to provide power through the trigger state, the laying of cables in the well to connect the circuit and other settings are avoided, the workload caused by laying cables is reduced, the setting of consumables is reduced, and the setting of the thermal battery assembly provides a long-term and stable energy supply demand to meet the needs of underground environmental monitoring. The present application effectively solves the problem that the underground alarm in the prior art needs to lay cables for power supply, the cable laying process is complicated, and there are problems such as line aging that cause the alarm to fail.

[0035] It should be noted that the thermal battery assembly 20 is used for long-term waiting work, and a thermal battery is mainly arranged inside it. The thermal battery is also called a molten salt battery and a heat-activated reserve battery. The electrolyte is a non-conductive solid during storage. When in use, the heating agent inside is ignited by an electric ignition head or a striker mechanism, so that the electrolyte melts and becomes an ion conductor and is activated. It is a primary reserve battery that uses molten salt as the electrolyte and uses an automatic activation mechanism to ignite a heat source to melt and activate the electrolyte. Therefore, such a reserve energy can be stored stably for a long time and release electrical energy only when it needs to be activated. On the one hand, it can ensure the effective function of the energy supply mechanism, and on the other hand, it can avoid laying a large number of cables, reduce time outside of production, improve production efficiency, and also save the electrical energy consumed by the cable, reducing the energy consumption of underground operations. Due to the use of the setting of the thermal battery assembly 20, the induction structure 31 adopts a structure or material that can change according to the physical information of the environment, so as to facilitate the determination of the triggering conditions through environmental conditions. Such a setting can meet the applicable conditions of the thermal battery assembly 20 and can better perform the alarm alarm operation task.

[0036] In the technical solution of this embodiment (not shown in the figure), the sensing structure 31 is a temperature-sensitive glass, and the two ends of the sensing structure 31 are respectively against the base 10 and the trigger structure 32 to lock the trigger structure 32. When the ambient temperature is higher than a predetermined value, the temperature-sensitive glass breaks, and the trigger structure 32 is in a triggered state. The temperature-sensitive glass can change its physical properties to a certain extent according to the ambient temperature. For example, at a certain temperature, the hardness of the temperature-sensitive glass decreases. Under the action of external force or a substance set inside it, the temperature-sensitive glass breaks. After the temperature-sensitive glass breaks, the trigger structure 32 against it loses its function restriction, and then performs a trigger operation to achieve the effect of activating the thermal battery assembly 20.

[0037] It should be noted that the base 10 in the present application includes a first base 11 and a top cover 14, and the first base 11 and the top cover 14 are threadedly connected, and the specific position of the top cover 14 can be adjusted. Specifically, the trigger structure 32 is provided with a mounting structure adapted to the temperature-sensitive glass, and the temperature-sensitive glass is arranged in the mounting structure. The top cover 14 is movably located in the first base 11 through a threaded connection, and the end of the temperature-sensitive glass away from the trigger structure 32 is against the top cover 14. During installation, the temperature-sensitive glass is placed on the trigger structure 32, and then the top cover 14 is rotated to move in the direction close to the temperature-sensitive glass, thereby clamping the temperature-sensitive glass. The setting of the threaded connection is conducive to the precise adjustment of the position of the top cover 14, ensuring the stable installation of the temperature-sensitive glass. On the other hand, the threaded connection has a self-locking function. After the clamping is completed, the top cover 14 will not rotate due to the thrust in the axial direction, thereby causing failure.

[0038] like Figures 1 to 4 As shown, in the technical solution of this embodiment, the trigger structure 32 includes a fixed seat 321, a first push rod 322, a locking member 323 and a second push rod 324. The fixed seat 321 is fixedly arranged in the base 10, and the first end of the first push rod 322 is against the sensing structure 31. The first push rod 322 is slidably arranged in the fixed seat 321. The locking member 323 is arranged between the first push rod 322 and the second push rod 324. When the temperature-sensitive glass is broken, the first push rod 322 slides in the direction close to the temperature-sensitive glass, the locking member 323 is separated from the second push rod 324, and the second push rod 324 triggers the thermal battery assembly 20 to activate. In the locked state, the first push rod 322 remains fixed, and the locking member 323 is locked between the first push rod 322 and the second push rod 324, and the second push rod 324 remains stationary at this time; in the triggered state, the temperature-sensitive glass is broken, contacting the restriction on the first push rod 322, and the first push rod 322 slides in the direction close to the temperature-sensitive glass, releasing the restriction on the locking member 323, and the locking member 323 contacts the restriction on the second push rod 324, and the second push rod 324 slides to activate the thermal battery assembly. Such a setting has a rigorous logical sequence, and the thermal battery is triggered by a purely mechanical method, which is quick and stable, and does not require an external power supply. The alarm using it can meet the needs of complex underground environments in the alarm warning function.

[0039] like Figure 3 , Figure 4 and Figure 6As shown, in the technical solution of this embodiment, a first elastic member 325 is provided between the first push rod 322 and the fixing seat 321, and the first elastic member 325 applies thrust to the first push rod 322 and the fixing seat 321 respectively. The function of the first elastic member 325 is to push the first push rod 322. When the temperature-sensitive glass is broken, the first push rod can push along the direction of the temperature-sensitive glass, thereby releasing the locking member 323, and the first elastic member 325 can withstand a certain pressure during installation. On the one hand, it converts the driving force of the torsion of the top cover 14 into elastic potential energy storage, and on the other hand, it plays a certain pushing effect on the first push rod 322, and then converts it into a pushing effect on the temperature-sensitive glass, so that a certain preliminary clamping force can be formed on the temperature-sensitive glass, which is conducive to adjusting the clamping force according to the properties of the temperature-sensitive glass, and then adjusting the control requirements for different temperatures and adjusting the breaking conditions of the temperature-sensitive glass.

[0040] Some existing mines are sensitive to high temperature environments. To prevent potential risks caused by high temperature environments, alarms and cooling systems are generally installed. The devices that power the alarms and cooling systems are generally divided into cable laying electricity. Cable laying electricity has a wide range of power consumption environments, and the laying network is relatively complex. It requires regular maintenance by professionals, and the laying time is long, which will cause line aging problems.

[0041] The embodiments of the present application can solve the problem of only supplying power in sudden high temperature situations, thereby saving power supply efficiency; no electronic components are provided, thereby ensuring normal power supply output in harsh high temperature environments.

[0042] When the ambient temperature reaches a predetermined value, the temperature-sensitive glass beads break, the first elastic member 325 pushes the first push rod 322 to move upward, the locking member 323 is released, and the second elastic member 326 pushes the sliding section 3241 and the push plate 3242, thereby pushing the magnetic field component 41 in the linear motor to move. The induction component 42 moves relative to the magnetic field, cutting the magnetic induction lines of the linear motor skeleton coil, generating instantaneous voltage, which is transmitted to the input end of the thermal battery assembly 20 through the power connection structure and the wire, thereby stimulating the internal electrical pyrotechnics of the thermal battery assembly 20, and the thermal battery assembly 20 works and supplies energy to the outside through the output end.

[0043] It should be noted that if Figures 5 to 8 As shown, in the technical solution of this embodiment, the base 10 includes a first base body 11, a second base body 12 and a third base body 13, wherein the first base body 11 is provided with a first installation cavity 111, a limiting groove 112, a limiting cavity 113 and a first sliding cavity 114, the first installation cavity 111 is used for the installation of the sensing structure 31, and a through hole with an internal thread is provided on the top of the first base body 11 for the installation of the top cover 14, and the through hole with the internal thread is connected to the first installation cavity 111.

[0044] The first seat body 11 is provided with a first limiting step 3211 and a second limiting step 3212, wherein the first limiting step 3211 is adapted to the limiting groove 112 to limit the fixing seat 321 from moving in a direction away from the sensing structure 31. The first push rod 322 is provided with a receiving groove 3221, a receiving cavity 3222 and a third limiting step 3223, the third limiting step 3223 is formed on the side of the first push rod 322, the diameter of the rod body close to the sensing structure 31 is smaller than the diameter of the part away from the sensing structure 31, and the third limiting step 3223 is formed between the two sections of the rod body, and the second limiting step 3212 is used to cooperate with the third limiting step 3223 to limit the maximum extension distance of the first push rod 322, so as to prevent the first push rod from sliding out directly after the sensing glass is broken. The setting of each limiting step also prevents the temperature sensing glass from entering the gap between the components when it is broken, and then getting stuck, resulting in activation problems and affecting the function of the alarm.

[0045] Furthermore, the accommodating groove 3221 is used for placing and installing the temperature-sensitive glass, which is specifically hemispherical, and the corresponding temperature-sensitive glass is also configured to be hemispherical. Such a combination can increase the contact area between the temperature-sensitive glass and the accommodating groove 3221, and thus the situation in which the pressure at a certain point is too high when the sensing glass is clamped, causing the sensing glass to directly shatter will not occur.

[0046] The accommodation cavity 3222 is used to install the first elastic member 325, so that the pushing direction of the first elastic member 325 will not move or change, thereby ensuring the function of pushing the first push rod 322. Specifically, a bottom cover 3213 is also provided at the bottom of the fixing seat 321. The bottom cover 3213 and the fixing seat 321 are threadedly connected. The space formed between the bottom cover 3213 and the accommodation cavity 322 is used to accommodate the first elastic member 325. Such a setting makes the bottom cover 3213 a fixed connection, thereby providing the fixing conditions of the first elastic member 325, and such a setting enables the first push rod 322 to be effectively and stably installed, with a compact structure and better pushing effect.

[0047] like Figure 3 , Figure 4 and Figure 6 As shown, in the technical solution of this embodiment, a second elastic member 326 is provided between the second push rod 324 and the base 10, and the second elastic member 326 applies thrust to the second push rod 324 and the base 10 respectively. The second elastic member 326 is provided to push the second push rod 324, thereby realizing the excitation of the thermal battery assembly 20. The excitation of the thermal battery assembly 20 can be activated by a needle piercing the primer cap, etc., and the side of the second push rod 324 away from the second elastic member 326 can be correspondingly set to be needle pierced.

[0048] It should be noted that a push step is formed on the outer side of the second push rod 324, and the second elastic member 326 is arranged between the first sliding cavity 114 and the second push rod 324. The push step of the second push rod 324 is offset against the second elastic member 326. Such a setting structure is more compact and makes full use of the space in the first sliding cavity 114. The second elastic member 326 can also play a certain isolation role to avoid problems in the assembly of the second push rod 324.

[0049] like Figure 3 and Figure 4 As shown, in the technical solution of this embodiment, the energy supply mechanism also includes a power generation assembly 40, and the power generation assembly 40 includes a magnetic field component 41 and an induction component 42. When the induction structure 31 and the trigger structure 32 are in the trigger state, the second push rod 324 slides in a direction away from the induction structure 31, so that the induction component 42 is relatively displaced relative to the magnetic field component 41, and an induced current is output to the thermal battery assembly 20. The power generation assembly 40 is configured to generate an induced current. The induced current generated by such a configuration is more suitable for activating the thermal battery assembly 20. Compared with the configuration of the needle piercing cap, it has a certain excitation failure rate, and the configuration of generating the induced current can ensure that the thermal battery assembly 20 is activated by adding current.

[0050] It should be noted that the induction component 42 is an induction coil, and the magnetic field component 41 is a magnetic body with regular magnetic field lines, which can be a permanent magnet. When the magnetic field component 41 slides, the induction coil formed by the induction component 42 can generate an induced current. The induction component 42 is fixedly arranged in the second sliding cavity 121 of the second seat body 12, and the permanent magnet passes through the induction component 42 and is slidably located in the second sliding cavity 121. The side of the second sliding cavity 121 away from the first seat body 11 is connected to the third sliding cavity 122, and the third sliding cavity 122 can accommodate part of the permanent magnet, and limit the permanent magnet to prevent the permanent magnet from passing through the second seat body 12 and contacting other components at the bottom.

[0051] like Figure 3 , Figure 4 and Figure 6 As shown, in the technical solution of this embodiment, the second push rod 324 includes a sliding section 3241 and a push plate 3242. The sliding section 3241 is arranged around the outer side of the fixed seat 321, and the sliding section 3241 and the push plate 3242 are detachably connected by fasteners. Such a setting not only satisfies the sliding setting of the second push rod 324, but also satisfies the function of isolating the first push rod 322 from the magnetic field component 41. When assembling, the part of the sliding section 3241 can better adapt to its assembly environment, and the push plate 3242 can also hold the first push rod 322 and the fixed seat 321 after assembly.

[0052] like Figure 3 , Figure 4 and Figure 6 As shown, in the technical solution of this embodiment, the sliding section 3241 and the push plate 3242 form a first limiting space, and the second limiting space is provided on the peripheral side of the fixed seat 321 facing the second push rod 324. When the sensing structure 31 and the trigger structure 32 are in the locked state, the first limiting space is connected to the second limiting space, and the locking member 323 is located in the first limiting space and the second limiting space, and the locking member 323 is against the side wall of the first push rod 322. The first limiting space and the second limiting space are provided to accommodate the locking member 323. At the same time, after the fixed seat 321 is fixedly installed, the fixed seat 321 and the second push rod 324 are connected by the position of the locking member, so as to prevent the second push rod 324 from sliding down. After the second push rod 324 is changed to the triggered state, the second push rod 324 is pressed toward the bottom of the first push rod 322 by the inclined surface of the first limiting space under the action of gravity and the elastic force of the second elastic member 326, thereby completing the unlocking.

[0053] Specifically, the first limiting space is an arc-shaped space with a triangular cross-section, the space has an opening of an arc-shaped surface, and the opening of the arc-shaped surface coincides with the outer cylindrical surface of the fixing seat 321. The outer cylindrical surface of the corresponding fixing seat 321 is provided with a through groove with the same arc length as the first limiting space, and the cross-section of the through groove is rectangular. When in the locked state, the outer peripheral edge of the first push rod 322 coincides with the inner cylindrical surface of the through groove. Such an arrangement makes it easy to process parts and components and the structure is more compact. The locking member 323 is specifically a steel ball. In the triangular space, when the contact is locked, the first limiting space slides along the axial direction, so that the inclined surface pushes the steel ball. When the steel ball is released from the restriction, the steel ball slides out of the second limiting space, thereby achieving the final unlocking.

[0054] like Figure 3 , Figure 4 and Figure 6 As shown, in the technical solution of this embodiment, the first limit space is provided with a first inclined surface and a second inclined surface connected to each other along the axis direction of the second push rod 324, and the connecting surface of the sliding section 3241 and the pushing plate 3242 extends along the axis direction away from the second push rod 324. Such a setting realizes the effect of the inclined surface pushing the steel ball, and its release logic is clear, and there will be no false touch. In addition, the purely mechanical structure setting can ensure that it can always maintain the working state in the complex environment of the mine, and avoid the occurrence of situations such as untimely fighting alarms due to restrictions such as laying cables.

[0055] It should be noted that if Figures 3 to 6As shown, in the embodiment of the present application, the base 10 also includes a third base 13, the thermal battery assembly 20 is arranged in the second installation cavity 131 of the third base 13, and the third base 13 is also provided with a circuit control assembly 50, the circuit control assembly 50 includes a power connection structure and a circuit board structure, the power connection structure is used to connect the positive and negative electrodes of the thermal battery assembly 20, the circuit board structure can be used for alarm control and circuit control, the induction current generated by the induction component 42 is first transmitted to the circuit board structure, the circuit board structure sends out an excitation current, the excitation current is used to activate the thermal battery assembly 20 to ignite, and then the thermal battery assembly 20 provides a more stable current supply, and at this moment the alarm is controlled by the circuit board structure. Such a setting is used to control the size and stability of the excitation current to ensure that the thermal battery assembly 20 can be activated.

[0056] In the technical solution of this embodiment, the installation process of the energy supply mechanism is as follows:

[0057] The fixing seat 321 is installed in the first seat body 11 and fixed by fasteners.
