Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof water bags, in particular to a water volume detection device for explosion-proof water bags used in coal mines. Background Art

[0002] Flameproof water bags are installation containers used in coal mines. The water bag sheds assembled according to the installation technical requirements can effectively isolate the spread of gas and coal dust explosions and reduce the losses caused by disasters. They are widely used underground. However, for a long time, the detection of water volume in flameproof water bags has relied on frequent manual climbing measurements, which is risky, labor-intensive, and has large deviations in measurement data.

[0003] Based on the above reasons, the utility model provides a water volume detection device for a flameproof water bag for coal mines. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a flameproof water bag water volume detection device for coal mines, which is hung on the top of the side wall of the flameproof water bag through a water absorption elbow, and its inner end is inserted into the inner cavity of the flameproof water bag. The other end of the water absorption elbow is connected to the negative pressure ball through a water guide pipe. The user presses the negative pressure ball to form a negative pressure inside it. If the inner end of the water absorption elbow is inserted under the water surface, the water in the flameproof water bag can enter the negative pressure ball through the water absorption elbow and the water guide pipe, indicating that the amount of water in the flameproof water bag is sufficient. If no water is sucked out, it means that the amount of water is insufficient and water needs to be replenished in time, which changes the original observation mode of "one person holding the ladder and one person climbing up", and only one person is needed to easily complete the observation work. It greatly improves the monitoring accuracy, reduces the labor intensity of employees, improves the monitoring efficiency, effectively avoids the risk of personnel climbing operations, and promotes the creation of an intrinsically safe environment for positions.

[0015] The beneficial effects of the utility model are:

[0016] (1) The utility model is hung on the top of the side wall of the explosion-proof water bag through a water absorption elbow, and its inner end is inserted into the inner cavity of the explosion-proof water bag.

The water absorption elbow 2 is hung on the top of the side wall of the explosion-proof water bag 1, and its inner end is inserted into the inner cavity of the explosion-proof water bag 1. The other end of the water absorption elbow 2 is connected with the negative pressure ball 4 through the water guide pipe 3. The user presses the negative pressure ball 4 to form a negative pressure inside it. If the inner end of the water absorption elbow 2 is inserted under the water surface, the water in the explosion-proof water bag 1 can enter the negative pressure ball 4 through the water absorption elbow 2 and the water guide pipe 3, indicating that there is sufficient water in the explosion-proof water bag 1. If no water is sucked out, it is necessary to replenish water in time, which changes the original observation mode of "one person holding the ladder and one person climbing up", and only one person is needed to easily complete the observation work. It greatly improves the monitoring accuracy, reduces the labor intensity of employees, improves the monitoring efficiency, effectively avoids the risk of personnel working at heights, and promotes the creation of an inherently safe environment at the post; preferably, the bottom of the negative pressure ball 4 is connected to a collecting bag 15 through a drain pipe 6, and a gate is provided on the drain pipe 6. When negative pressure suction is required, the gate is closed. When water is absorbed by the negative pressure ball, the gate is opened to discharge the water into the collecting bag 15; in addition, preferably, the water guide pipe 3 is a telescopic pipe, so that it can adapt to the water volume detection of explosion-proof water bags 1 at different heights.

[0028] Furthermore, the water absorption elbow 2 includes a bend section 8 and a telescopic section 9, the bend section 8 is a semicircular ring structure, the bottom of the outer end is connected to the top of the water pipe 3, and the bottom of the inner end of the bend section 8 is connected to the top of the telescopic section 9. This embodiment can detect the water volume at different depths of the explosion-proof water bag 1 through the telescopic section 9, and the detection is accurate.

[0029] Furthermore, the telescopic section 9 includes a first telescopic tube 91, a second telescopic tube 92 and a third telescopic tube 93. A first limiting ring 911 is provided below the inner wall of the first telescopic tube 91. The outer diameter of the second telescopic tube 92 is equal to the inner diameter of the first limiting ring 911. A second limiting ring 921 is provided above the outer wall of the second telescopic tube 92. A first sealing ring groove for clamping the first sealing ring 94 is provided in the middle of the outer wall of the second limiting ring 921. A third limiting ring 922 is provided below the inner wall of the second telescopic tube 92. The outer diameter of the third telescopic tube 93 is equal to the inner diameter of the third limiting ring 922. A fourth limiting ring 931 is provided above the outer wall of the third telescopic tube 93. A second sealing ring groove for clamping the second sealing ring 95 is provided in the middle of the outer wall of the fourth limiting ring 931. The top end of the first telescopic tube 91 is connected to the inner bottom end of the curved pipe section 8. The telescopic section 9 can be retracted into the first telescopic tube 91 by setting The second telescopic tube 92 and the third telescopic tube 93 that can be retracted into the second telescopic tube 92 can divide the water amount in the explosion-proof water bag into water shortage, moderate and full for detection. Initially, the second telescopic tube 92 is retracted into the first telescopic tube 91, and the third telescopic tube 93 is retracted into the second telescopic tube 92. At this time, the telescopic section 9 is in the shortest state. If the user presses the negative pressure ball 4 to suck out water from the explosion-proof water bag 1 at this time, the water amount in the explosion-proof water bag 1 is full and no water needs to be added. If no water is sucked out at this time, the second telescopic tube 92 is extended. If the negative pressure ball 4 can suck out water at this time, the water amount in the explosion-proof water bag 1 is moderate, and the sequence to be added water can be noted, and no water needs to be added immediately. If no water is sucked out at this time, the second telescopic tube 92 and the third telescopic tube 93 are both extended. If the negative pressure ball 4 cannot suck out water at this time, the water amount in the explosion-proof water bag 1 is water shortage, and water needs to be replenished in time to ensure that the explosion-proof water bag 1 can play its protective role.

[0030] Furthermore, the outer wall of the first sealing ring 94 is in tight contact with the inner wall of the first telescopic tube 91; the outer wall of the second sealing ring 95 is in tight contact with the inner wall of the second telescopic tube 92, and the static friction between the first sealing ring 94 and the first telescopic tube 91, and between the second sealing ring 95 and the second telescopic tube 92 can ensure that the second telescopic tube 92 and the third telescopic tube 93 will not be accidentally extended when the staff does not want them to be extended, thereby affecting the accuracy of water volume detection.

[0031] Furthermore, a fifth limiting ring 923 and a sixth limiting ring 932 are respectively provided below the outer walls of the second telescopic tube 92 and the third telescopic tube 93 to ensure that the bottom end of the second telescopic tube 92 will not be completely retracted into the first telescopic tube 91 and the third telescopic tube 93 will not be completely retracted into the second telescopic tube 92.

[0032] Furthermore, the bracket 5 has a square frame structure, and the explosion-proof water bag 1 is hung on the bracket 5 through a hanging piece 14, and the hanging piece 14 has an "S"-shaped structure; a plurality of hanging holes for inserting the bottom end of the hanging piece 14 are provided at intervals above the outer walls on both sides of the explosion-proof water bag 1, and the top end of the hanging piece 14 is hung on the bracket 5. During installation, the lower end of the S-shaped hanging piece 14 is hung on the hanging hole, and the upper end of the hanging piece 14 is hung in the length direction of the bracket 5.

[0033] Furthermore, the vertical distance a between the top of the curved pipe section 8 and the bottom of the telescopic section 9 is not greater than the vertical distance b between the bottom of the bracket 5 and the top of the explosion-proof water bag 1, ensuring that the second telescopic tube 92 and the third telescopic tube 93 of the telescopic section 9 are both extended. When the telescopic section 9 is in its longest state, the telescopic section 9 and the curved pipe section 8 can extend into the gap between the bracket 5 and the explosion-proof water bag 1, thereby performing water volume detection.

[0034] Furthermore, a gripping handle 10 is sleeved on the outer side of the lower outer wall of the water pipe 3, and a finger groove 11 is provided on one side of the outer wall of the gripping handle 10, which can facilitate the user to move the water level detection device more comfortably and with less effort; a limiting rod 12 is connected to the upper side of the other side of the outer wall of the gripping handle 10, and the limiting rod 12 is vertically arranged to the water pipe 3 to prevent the user from sliding in the vertical direction when holding the water pipe 3.

[0035] Furthermore, bubble levels 13 are fixed on the outer walls of both sides of the limit rod 12 in the horizontal direction. By setting the bubble level 13, it is ensured that the limit rod 12 is in the horizontal direction, and the water pipe 3 and the telescopic tube 9 are in the vertical state, thereby ensuring the accuracy of water volume detection.

[0036] The above description is only an embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent transformation made by using the contents of the specification and drawings of the present utility model or directly or indirectly applied in the relevant technical field is also included in the patent protection scope of the present utility model.
