Description

Technical Field

[0001] This utility model relates to the field of underground equipment technology in coal mines, specifically to a comprehensive protection battery system for underground battery-powered locomotives in coal mines. Background Technology

[0002] As the core power equipment for underground material transportation and personnel commuting, underground battery-powered locomotives in coal mines undertake the critical transportation task of connecting the mining face, the underground yard, and the surface. Their operational stability directly determines the underground production efficiency and operational continuity. The performance of the battery, which is the power source of the locomotive, is the most critical issue. Problems such as capacity decay and reduced charging and discharging efficiency can not only lead to shortened locomotive range and mid-journey stoppages, but may also cause congestion on underground transportation lines and even affect the timeliness of emergency operations such as disaster relief, posing a direct threat to safe production.

[0003] The charge-discharge performance of lead-acid batteries is closely related to temperature. Their temperature profiles reflect the changes in capacity, efficiency, and lifespan under different temperature conditions. Example of a typical temperature-capacity profile.

[0004]

[0005] Current battery protection technologies often focus on single functions and lack systematic solutions, failing to meet the comprehensive protection requirements of the electrolyte in complex downhole environments. Therefore, a comprehensive protection system is needed to achieve dynamic control of battery heat dissipation and electrolyte levels, significantly improving battery performance, lifespan, and safety, and ensuring long-term stable operation of the battery downhole. Its specific functions are as follows:

[0006] I. Extending battery life – slowing down plate corrosion

[0007] High temperatures (>45℃) accelerate electrolyte decomposition and grid corrosion. Temperature regulation can stabilize the temperature at around 25℃, inhibiting the corrosion rate. Experiments show that for every 10℃ decrease in temperature, float charge life can be extended by approximately 30%.

[0008] II. Enhanced safety protection – preventing electrolyte drying and inhibiting gas evolution

[0009] At high temperatures, the float charge voltage automatically decreases (e.g., 3mV / cell for every 1°C increase) to reduce water molecule electrolysis and prevent the electrolyte from drying out.

[0010] The temperature control system reduces hydrogen and oxygen evolution reactions at high temperatures by adjusting the charging and discharging rates, thereby lowering the risk of explosion.

[0011] III. Improved Economic Efficiency – Reduced Replacement Costs and Maintenance Investment

[0012] Adjusting the temperature can extend battery life from 2 years (without temperature control) to 1 year, reducing the frequency of replacement.

[0013] A constant temperature environment reduces the probability of plate corrosion and sulfidation, and reduces the frequency of equalization charging and manual maintenance. Summary of the Invention

[0014] The technical problem to be solved by this utility model is to provide a comprehensive protection battery system for underground coal mine electric locomotives. It can effectively solve the problem that the existing battery protection technology focuses on single functions and lacks a systematic solution, and cannot meet the comprehensive protection needs of electrolyte in the complex underground environment.

[0015] The technical solution adopted by this utility model is: a comprehensive protection battery system for underground coal mine electric locomotives, including a mounting housing and a plurality of battery bodies set at the top of the mounting housing. A heat dissipation box is set at the bottom of the battery body. A heat dissipation component is set on the outer wall of the heat dissipation box. A slot and a positioning groove are opened on the inner wall of the heat dissipation box. A buffer plate is set on the inner wall of the heat dissipation box. Insert blocks are fixedly installed at both ends of the buffer plate. Through holes are opened on the outer wall of the buffer plate. A positioning block and insert block two are fixedly installed at one end of the battery body near the heat dissipation box. An electrolyte density adjustment component is set at the top of the mounting housing.

[0016] The electrolyte density adjustment assembly includes a distilled water delivery pipe assembly and an electrolyte concentration detector. The distilled water delivery pipe assembly is provided at the top of the mounting housing, and the electrolyte concentration detector is fixedly installed on the inner wall of the battery body.

[0017] Through the above technical solution, the electrolyte concentration detector detects the concentration of electrolyte inside the battery body, and then adds distilled water through the distilled water delivery pipe group to maintain the concentration of electrolyte inside the battery body, so as to avoid plate corrosion and capacity decay caused by high temperature evaporation or low temperature condensation.

[0018] Preferably, the heat dissipation component includes a first water inlet pipe, a second water inlet pipe, a first water outlet pipe, and a second water outlet pipe. The inner wall of the mounting housing is provided with a first water inlet pipe, a second water inlet pipe, a first water outlet pipe, and a second water outlet pipe. The first water inlet pipe, the second water inlet pipe, the first water outlet pipe, and the second water outlet pipe are connected to the heat dissipation box.

[0019] Through the above technical solution, the staff connects the external water source to the first water inlet pipe. Then, the water enters the interior of the heat sink through the first and second water inlet pipes. The water comes into direct contact with the outer wall of the battery body, which helps to dissipate heat from the battery body and improves the service life of the battery body. It is highly practical.

[0020] Preferably, the first insert and the slot are plugged in, and the cross-section of the first insert has a "T" shape.

[0021] With the above technical solution, the staff can quickly position the buffer plate by inserting the plug into the slot. Without complicated calibration operations, the relative position of the buffer plate and the heat sink can be ensured to be accurate, which improves installation efficiency, reduces labor and time costs, and has high practicality.

[0022] Preferably, a hook is fixedly installed on the outer wall of the battery body, a latch is fixedly installed on the outer wall of the heat sink near the battery body, the positioning block and the positioning groove are plugged in, the second plug block and the slot are plugged in, the cross-section of the second plug block is a "T" shaped structure, and the latch is compatible with the hook.

[0023] With the above technical solution, after the buffer plate is quickly positioned, the staff inserts the positioning block into the positioning slot and inserts the second insert into the slot, which can realize the quick positioning of the heat sink and the quick limiting of the buffer plate. Then, the staff locks the heat sink to the battery body by using the cooperation of the latch and hook, which can realize the quick installation of the heat sink and facilitate its maintenance or replacement after long-term use.

[0024] Preferably, the buffer plate has an "H" shaped cross-section, the upper end of the buffer plate does not contact the battery body, and the lower end of the buffer plate does not contact the heat sink.

[0025] With the above technical solution, during the operation of the locomotive, the water inside the heat sink shakes to a great extent, repeatedly impacting the inner wall of the heat sink, making the heat sink prone to damage. The design of the buffer plate can effectively reduce the impact force of the water on the inner wall of the heat sink, which is highly practical.

[0026] Preferably, the through holes are provided in a plurality of identical manner, and the plurality of through holes are distributed at equal intervals. The buffer plates are provided in a plurality of identical manner, and the plurality of buffer plates are distributed at equal intervals.

[0027] The above technical solution, through the design of multiple through holes and buffer plates, further reduces the impact of water on the inner wall of the heat sink and improves its service life.

[0028] Preferably, the outer wall of the battery body is provided with a mounting groove, and the inner wall of the mounting groove is provided with a sealing ring. The sealing ring is a rubber ring, and three identical sealing rings are provided, which are distributed at equal intervals.

[0029] The above technical solution utilizes the rubber ring's excellent sealing properties. By designing the sealing ring, water inside the heat sink is prevented from leaking out through the connection between the heat sink and the battery body, resulting in high sealing performance. The design of three sealing rings further enhances the overall sealing performance.

[0030] Compared with the prior art, this utility model provides a comprehensive protection battery system for underground coal mine electric locomotives, which has the following beneficial effects:

[0032] 2. This integrated protection battery system for underground coal mine electric locomotives, through the design of plug block one and slot, can achieve rapid positioning of the buffer plate without complicated calibration operations, ensuring accurate relative position of the buffer plate and heat sink, improving installation efficiency, reducing labor and time costs, and has high practicality. Through the cooperation of positioning block and positioning groove with plug block two and slot, the heat sink can be quickly positioned, and the buffer plate can be quickly limited. Through the cooperation of latch and hook, the heat sink can be quickly installed. After long-term use, it is convenient to inspect or replace it.

[0042] 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.

[0043] Example 1:

[0044] like Figure 1-7 As shown, the present invention provides a comprehensive protection battery system for underground coal mine electric locomotives, including a mounting housing 1 and a plurality of battery bodies 2 disposed at the top of the mounting housing 1. A heat dissipation box 3 is disposed at the bottom of the battery body 2. A heat dissipation component 4 is disposed on the outer wall of the heat dissipation box 3. A slot 5 and a positioning groove 9 are opened on the inner wall of the heat dissipation box 3. A buffer plate 6 is disposed on the inner wall of the heat dissipation box 3. Insert blocks 7 are fixedly installed at both ends of the buffer plate 6. A through hole 8 is opened on the outer wall of the buffer plate 6. A positioning block 10 and an insert block 11 are fixedly installed at one end of the battery body 2 near the heat dissipation box 3. An electrolyte density adjustment component 16 is disposed at the top of the mounting housing 1.

[0045] The electrolyte density adjustment assembly 16 includes a distilled water delivery pipe assembly 1601 and an electrolyte concentration detector 1602. The distilled water delivery pipe assembly 1601 is provided at the top of the mounting housing 1, and the electrolyte concentration detector 1602 is fixedly installed on the inner wall of the battery body 2.

[0046] Specifically, the heat dissipation component 4 includes a first water inlet pipe 401, a second water inlet pipe 402, a first water outlet pipe 403, and a second water outlet pipe 404. The inner wall of the mounting housing 1 is equipped with these pipes, and they are connected to the heat dissipation box 3. The advantage is that when an external water source is connected to the first water inlet pipe 401, water enters the heat dissipation box 3 through the first and second water inlet pipes 401 and 402. The water directly contacts the outer wall of the battery body 2, effectively dissipating heat and extending its lifespan. This design is highly practical.

[0047] Specifically, the insert 7 and slot 5 are installed by plugging in, and the cross-section of the insert 7 is T-shaped. The advantage is that the operator can quickly position the buffer plate 6 by inserting the insert 7 into the slot 5 without complicated calibration operations, which can ensure the accurate relative position of the buffer plate 6 and the heat sink 3, improve installation efficiency, reduce labor and time costs, and has high practicality.

[0048] Specifically, a hook 12 is fixedly installed on the outer wall of the battery body 2, and a latch 13 is fixedly installed on the outer wall of the heat sink 3 near the end of the battery body 2. The positioning block 10 and the positioning groove 9 are plugged into each other, and the second plug block 11 and the slot 5 are plugged into each other. The cross-section of the second plug block 11 is T-shaped, and the latch 13 and the hook 12 are compatible. The advantage is that after the buffer plate 6 is quickly positioned, the operator inserts the positioning block 10 into the positioning groove 9 and the second plug block 11 into the slot 5, which can realize the quick positioning of the heat sink 3 and the quick limiting of the buffer plate 6. Then, the operator locks the heat sink 3 and the battery body 2 together by the cooperation of the latch 13 and the hook 12, which can realize the quick installation of the heat sink 3 and facilitate its maintenance or replacement after long-term use.

[0049] Example 2:

[0050] like Figure 2-7 As shown, as an improvement on the previous embodiment, to further reduce the impact force of water on the inner wall of the heat sink 3, specifically, the buffer plate 6 has an "H"-shaped cross-section. The upper end of the buffer plate 6 does not contact the battery body 2, and the lower end of the buffer plate 6 does not contact the heat sink 3. The advantage is that during the operation of the locomotive, the water inside the heat sink 3 experiences significant sloshing, repeatedly impacting the inner wall of the heat sink 3, making it prone to damage. The design of the buffer plate 6 effectively reduces the impact force of water on the inner wall of the heat sink 3, making it highly practical.

[0051] Specifically, multiple identical through holes 8 are provided, and these through holes 8 are evenly spaced. Similarly, multiple identical buffer plates 6 are provided, and these buffer plates 6 are also evenly spaced. The advantage is that the design of multiple through holes 8 and buffer plates 6 further reduces the impact of water on the inner wall of the heat sink 3, thus improving its service life.

[0052] Specifically, the outer wall of the battery body 2 has a mounting groove 14, and the inner wall of the mounting groove 14 is provided with a sealing ring 15. The sealing ring 15 is a rubber ring, and three identical sealing rings 15 are provided, which are evenly distributed. The advantage is that, because the rubber ring has good sealing performance, the design of the sealing ring 15 prevents water inside the heat sink 3 from leaking out through the connection between the heat sink 3 and the battery body 2, resulting in high sealing performance. The design of three sealing rings 15 further improves the overall sealing performance.

[0053] Working Principle: During installation, the operator inserts the first insert 7 into the slot 5, enabling rapid positioning of the buffer plate 6. This eliminates the need for complex calibration, ensuring accurate relative positioning between the buffer plate 6 and the heat sink 3, improving installation efficiency, reducing labor and time costs, and offering high practicality. After quickly positioning the buffer plate 6, the operator inserts the positioning block 10 into the positioning groove 9 and simultaneously inserts the second insert 11 into the slot 5, enabling rapid positioning of the heat sink 3 and rapid limiting of the buffer plate 6. The operator then uses the locking buckle 13 and hook 12 to lock the heat sink 3 to the battery body 2, enabling rapid installation of the heat sink 3. This facilitates maintenance or replacement after prolonged use. During use, the operator connects the external water source to the inlet pipe 401, and water flows through both inlet pipe 401 and inlet pipe 2. Water 402 enters the interior of the radiator 3, directly contacting the outer wall of the battery body 2, thus dissipating heat and extending its service life. This is highly practical. During locomotive operation, the water inside the radiator 3 experiences significant agitation, repeatedly impacting its inner wall, making it prone to damage. The buffer plate 6 effectively reduces the impact force of water on the inner wall of the radiator 3, further enhancing its practicality. Multiple through holes 8 and the buffer plate 6 further reduce the impact force, extending the service life. Due to the excellent sealing properties of the rubber rings, the sealing ring 15 prevents water from leaking out through the connection between the radiator 3 and the battery body 2, ensuring high sealing performance. The design of three sealing rings 15 further improves the overall sealing performance.

[0054] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
