Abstract
Description
Technical Field
[0001] This utility model relates to the field of early warning device technology, specifically an early warning device for water prevention and control in coal mines. Background Technology
[0002] Coal mine geological surveying and water control is an important technical task in coal mine safety production. It mainly involves the surveying and analysis of coal mine geological conditions, as well as comprehensive measures to prevent and control mine water hazards. In the process of water control, the use of early warning devices can promptly detect potential water hazards, take timely preventive measures, avoid water inrush accidents, and ensure mine safety.
[0003] In existing technologies, when monitoring water hazards in coal mines using early warning devices, float-type liquid level sensors are typically used. These sensors utilize the principle that the float, rising and falling with the liquid level, triggers a mechanical or magnetic switch. When the water level rises due to seepage in the coal mine, the float rises with the liquid surface due to buoyancy, thus triggering the switch. At this point, a buzzer sounds an alarm. However, in actual use, current early warning devices can only issue an alarm to remind people in the vicinity to evacuate in time, but they cannot pre-treat the rising water level. This causes the water level to continue to rise, leaving insufficient time for personnel to arrive and significantly increasing the difficulty of eliminating the seepage. Therefore, it is necessary to develop an improved early warning device for water prevention and control in coal mines to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide an early warning device for water control in coal mines, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an early warning device for water control in coal mines, comprising a housing, a lifting handle fixedly installed on the top of the housing, and an early warning processing mechanism and a lifting installation mechanism disposed inside the housing.
[0006] Preferably, the early warning processing mechanism includes a signal receiving controller, which is fixedly installed on the front of the housing. A buzzer is fixedly installed on the top of the housing. A threaded rod is rotatably installed inside the housing via a rotating shaft. A limit rod and a water pump are fixedly installed on the inner top of the housing. A support frame is installed on the external thread of the threaded rod. A trigger switch is fixedly installed on the inner top of the support frame. A threaded head plug is slidably installed inside the support frame. A nut is installed on the external thread of the threaded head plug. A slide rod is slidably installed inside the threaded head plug. A float is fixedly installed at the bottom of the slide rod.

[0012] Compared with the prior art, this utility model provides an early warning device for water prevention and control in coal mines, which has the following beneficial effects:
[0013] 1. This early warning device for water control in coal mines, through its early warning processing mechanism, triggers a buzzer when the water level rises by contacting a contact head with a trigger switch. The height of the warning water level can be adjusted by assembling threaded inserts at different heights. The threaded rod ensures the float remains in contact with the ground at all times. Simultaneously, during the warning, a signal receiver controller drives a water pump to pump out the gradually rising water, allowing sufficient time to handle the rising water level and reducing the difficulty of treatment.
[0014] 2. This coal mine ground survey and water control early warning device, through the set lifting installation mechanism, can adjust the support height of the device during use by fixing the threaded rod and the threaded connection of the support leg. By using the grounded installation base plate, it can be stably installed on the ground, thus realizing the function of adjusting the installation height of the device. Attached Figure Description

[0023] 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.
[0024] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0025] Example:
[0026] Please see Figure 1-5This utility model provides a technical solution: an early warning device for water prevention and control in coal mines, including a shell 1, a lifting handle 4 fixedly installed on the top of the shell 1, and an early warning processing mechanism 2 and a lifting installation mechanism 3 arranged inside the shell 1.
[0027] Furthermore, the early warning processing mechanism 2 includes a signal receiving controller 21, which is fixedly installed on the front of the housing 1. A buzzer 22 is fixedly installed on the top of the housing 1. A threaded rod 23 is rotatably installed inside the housing 1 via a rotating shaft. A limit rod 24 and a water pump 212 are fixedly installed on the inner top of the housing 1. A support frame 25 is threaded onto the outer side of the threaded rod 23. A trigger switch 26 is fixedly installed on the inner top of the support frame 25. A threaded head insert 27 is slidably installed inside the support frame 25. A nut 28 is threaded onto the part of the pump 212. A slide rod 29 is slidably installed inside the threaded head insert 27. A float ball 210 is fixedly installed at the bottom of the slide rod 29. An abutment head 211 is fixedly installed at the top of the slide rod 29. A drain pipe 213 is fixedly installed on the right side of the pump 212. A pumping pipe 214 is fixedly installed on the left side of the pump 212. This allows the set early warning and processing mechanism 2 to monitor and warn of rising water levels inside the coal mine, while also pre-treating the water level to ensure that subsequent personnel have sufficient time to deal with the water level.
[0028] Furthermore, a storage slot is provided on the left side of the outer casing 1, and a counterweight pump head is provided at the end of the water pipe 214 away from the water pump 212. The counterweight pump head at the end of the water pipe 214 away from the water pump 212 is slidably installed inside the storage slot provided on the left side of the outer casing 1. The counterweight pump head ensures that the water pipe 214 can remain vertically downward when pumping water, and will not sway or shake due to the rise of water flow and impact. At the same time, the counterweight pump head is stored in the storage slot, which can prevent the water pipe 214 from being dragged and damaged during transfer and transportation. This improves the stability of water pumping pretreatment and ensures stable transportation.
[0029] Furthermore, the support frame 25 has holes at the corresponding positions of the limiting rod 24, and the limiting rod 24 is slidably installed inside the holes in the support frame 25. By sliding the limiting rod 24 inside the holes, the limiting rod 24 can effectively limit the support frame 25, thereby adjusting the high speed of the support frame 25 and allowing the height of the float 210 to be adjusted.
[0030] Furthermore, the support frame 25 has a positioning mounting hole inside, and the threaded head plug 27 is slidably installed inside the positioning mounting hole inside the support frame 25. Through the multiple positioning mounting holes, the threaded head plug 27 can be installed in different positions, thereby adjusting the distance between the contact head 211 and the trigger switch 26, so that the stroke of the warning trigger can be adjusted according to the needs.
[0031] Please see Figure 6 Furthermore, the lifting and mounting mechanism 3 includes a fixed threaded rod 31, which is fixedly installed on the top inner side of the outer casing 1. The fixed threaded rod 31 is threaded with a support leg 32, and the bottom of the support leg 32 is fixedly installed with a mounting base plate 33. Through the lifting and mounting mechanism 3, the support leg 32 can be stored during transportation and supported during use, which improves the convenience of transporting and moving the device.
[0032] Furthermore, the mounting base plate 33 has mounting holes inside, and these mounting holes are evenly distributed inside the mounting base plate 33. Through the multiple mounting holes, the support leg 32 can be fixed to the ground, thereby enabling it to support and raise the warning device during use.
[0033] In actual operation, when using this device, after transferring the device, manually lift the handle 4 and move the outer casing 1 to the position where installation warning is required. Rotate the support leg 32 to lower it. Once it reaches the required height, place the device on the ground and use expansion bolts and other external mounting parts to fix the mounting base 33 to the ground, thus completing the foundation fixing. Insert the threaded head insert 27 into the support frame 25 and tighten the nut 28 to fix the threaded head insert 27. Rotate the threaded rod 23 to lower the support frame 25 under the restriction of the limit rod 24, causing the float 210 to descend to the specified required height or to contact the ground. Furthermore, the counterweight pump head is removed from the storage tank, making the pump pipe 214 perpendicular to the ground. After the connecting drain pipe 213 is installed with the external coal mine drainage pipe, the warning can begin. When the water level rises inside the coal mine due to water seepage, the rise in water level will cause the float 210 to rise, causing the slide rod 29 to drive the contact head 211 to rise. After the contact head 211 touches the trigger switch 26, it will transmit a signal to the signal receiving controller 21. The signal receiving controller 21 controls the buzzer 22 to emit a warning buzzer sound and controls the water pump 212 to start pumping water. The water is discharged to the outside of the coal mine through the connecting drain pipe 213. This can achieve both warning and pre-treatment of the rising water level at the same time, ensuring that the personnel have enough time to handle the situation.
