[0034] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the water level measuring device of the coal mine water tank 1 of the utility model embodiment comprises a water tank 1, a bracket 2, a wire coil 3, a measuring head 4, a measuring plate 5 and an indicator light 6. The bracket 2 is arranged on the water tank 1, the wire coil 3 is rotatably arranged on the bracket 2 and a traction rope 31 is wound around the wire coil 3. The wire coil 3 is used to gather or release the traction rope 31. The measuring head 4 is connected to the end of the traction rope 31 and is used to dive into the water body of the water tank 1 and part of the measuring head 4 is used to sink into the silt in the water tank 1. The circumferential side of the measuring head 4 is provided with a spaced interval extending along the measuring head 4. The measuring plate 5 corresponds to the slide groove 41 one by one and one end of the measuring plate 5 is slidably arranged in the slide groove 41. The indicator light 6 is connected to a power supply. A first guide piece 61 and a second guide piece 62 are arranged in a connection circuit between the indicator light 6 and the power supply. The first guide piece 61 and the second guide piece 62 are respectively arranged on the measuring plate 5 and the slide groove 41. The measuring plate 5 is used to move relative to the measuring head 4 when the measuring head 4 sinks into the mud and make the first guide piece 61 and the second guide piece 62 electrically conductive to realize the closing of the connection circuit of the indicator light 6.

[0036] When the water level measuring device of the coal mine water tank 1 of the utility model embodiment is in use, the traction rope 31 is released through the wire coil 3, and the measuring head 4 is submerged into the water body in the water tank 1 under the gravity of the measuring head 4, and part of the measuring head 4 is sunk into the silt in the water tank 1. The measuring plate 5 moves relative to the measuring head 4 in the direction close to the traction rope 31 under the blocking effect of the silt. At this time, the first guide piece 61 and the second guide piece 62 are electrically conductive, and the indicator light 6 lights up, and the part of the traction rope 31 that is submerged in the water body and the part that is not submerged in the water body form a dividing line. The coil is rotated in reverse to gather the traction rope 31 and recover the measuring head 4. When the dividing line on the traction rope 31 rises above the tank body, it is marked, and the length of the traction rope 31 submerged in the water body is measured. When the first guide piece 61 and the second guide piece 62 are turned on, the distance from the measuring plate 5 to the end of the measuring head 4 connected to the traction rope 31 is measured. The two measured values ​​are added together to obtain the actual height of the water body in the water tank 1, and then the accurate volume of the water body in the water tank 1 can be obtained through the cross-sectional area of ​​the water tank 1.

[0037] The water level measuring device for the coal mine water tank 1 of the utility model embodiment is easy to operate and can quickly measure the actual water level of the water tank 1 so as to obtain an accurate value of the water volume in the water tank 1.

[0038] Optionally, a handle is provided on the rotating wheel.

[0039] Optionally, two or three slide grooves 41 are provided on the periphery of the measuring head 4 .

[0040] Optionally, a group of indicator lights 6 is provided, or a plurality of corresponding slide slots 41 are provided.

[0041] Optionally, the indicator light 6 is arranged on the traction rope 31.

[0042] Optionally, the indicator light 6 uses a button battery as a power source, and a connecting line of the indicator light 6 is connected to the first guide piece 61 and the second guide piece 62 at the same time.

[0043] In some embodiments, Figure 4 As shown, it includes a first spring 42, which is arranged in the slide groove 41 and has two ends respectively connected to the measuring plate 5 and the bottom of the slide groove 41, and the first spring is used to support the measuring plate 5 to move in the direction away from the traction rope 31.

[0044] When the measuring head 4 just enters the water body and after entering the water body, the water surface and the water body will provide upward buoyancy to the measuring plate 5 to push the measuring plate 5 to move relative to the measuring head 4. The first spring 42 pushes the measuring plate 5 to reduce the accidental touch of the first guide plate 61 and the second guide plate 62, thereby ensuring the detection accuracy of the indicator light 6.

[0045] In some embodiments, Figure 3 As shown, it includes a sealing cylinder 43, which is arranged in the slide groove 41 corresponding to the first guide plate 61 and the second guide plate 62, and the two ends of the sealing cylinder 43 are respectively sealed and connected to the measuring plate 5 and the slide groove 41. The sealing cylinder 43 can be telescopically folded along the extension direction of the measuring head 4, and the first guide plate 61, the second guide plate 62 and the first spring 42 are all arranged in the sealing cylinder 43.

[0046] The two ends of the sleeve are sealed with the measuring plate 5 and the slide groove 41 respectively to ensure that there is no water in the sleeve. When the measuring head 4 is not sunk into the mud, there is no electrical conduction between the first guide piece 61 and the second guide piece 62 to ensure the normal use of the first guide piece 61 and the second guide piece 62.

[0047] Optionally, the sealing tube 43 is made of rubber.

[0048] In some embodiments, Figure 4 As shown, it includes a first support rod 44 and a second support rod 45, which are respectively arranged on the side where the measuring plate 5 and the slide groove 41 are close to each other, the first support rod 44 and the second support rod 45 are both arranged in the first spring 42, and the first guide plate 61 and the second guide plate 62 are respectively arranged on the end where the first support rod 44 and the second support rod 45 are close to each other.

[0049] By setting the first support rod 44 and the second support rod 44, the distance that the measuring plate 5 moves relative to the measuring head 4 when the first guide piece 61 and the second guide piece 62 are electrically connected is reduced, so that the electrical connection between the first guide piece 61 and the second guide piece 62 is easily achieved, so as to accurately control the sinking position of the measuring head 4.

[0050] In some embodiments, Figure 2 , Figure 3 and Figure 4As shown, the measuring plate 5 includes a connecting rod segment 51 and a hinged plate segment 52 . One end of the connecting rod segment 51 is slidably disposed in the slide groove 41 . Two hinged plate segments 52 are provided and hingedly connected to the connecting rod segment 51 .

[0051] A hinged plate section 52 is provided. When the measuring head 4 sinks in the water body, the hinged plate section 52 rotates around the connecting rod section 51 to reduce the resistance encountered by the measuring head 4 when sinking, and reduce the displacement of the measuring plate 5 relative to the measuring head 4, so as to avoid the first guide plate 61 and the second guide plate 62 being turned on when the measuring head 4 has not sunk into the silt, thereby ensuring the accurate positioning of the measuring head 4 by the indicator light 6, so as to determine the accurate height of the water body in the water tank 1.

[0052] Optionally, the slide groove 41 is a T-shaped groove, and the end of the connecting rod segment 51 is arranged on a T-shaped sliding block, and the sliding block is slidably arranged in the slide groove 41.

[0053] In some embodiments, Figure 3 and Figure 4 As shown, it includes a second spring 53, which is fixedly connected between the two hinged plate segments 52, and the second spring 53 is arranged on the side of the connecting rod segment 51 close to the traction rope 31. The second spring 53 is used to support or pull the two hinged plate segments 52 to rotate around the connecting rod segment 51 in a direction away from each other.

[0054] By providing the second spring 53, it is ensured that when the measuring head 4 sinks into the mud, under the action of the second spring 53, the two hinged plate sections 52 can be opened to be laid flat on the top of the mud, so that the connecting rod section 51 can move relative to the measuring head 4 under the force of the mud, thereby achieving electrical conduction between the first guide plate 61 and the second guide plate 62.

[0055] In some embodiments, Figure 3 and Figure 4 As shown, a support rod 54 is correspondingly provided on each of the two hinged plate sections 52, and the support rod 54 is rotatably connected to the hinged plate section 52. The second spring 53 is sleeved on the support rod 54. By providing the support rod 54, the compression or extension axis of the second spring 53 is restricted to prevent the spring from bending and causing elastic failure.

[0056] Optionally, two ends of the second spring 53 are fixedly connected to the support rods 54 on the corresponding two hinged plate segments 52 .

[0057] In some embodiments, Figure 2 , Figure 3 and Figure 4As shown, it includes a baffle 7, which is arranged below the connecting rod section and fixedly connected to the connecting rod section 51. The baffle 7 cooperates with the hinged plate section 52 to prevent the two hinged plate sections from flipping downward at the same time to interfere with the sinking of the measuring head 4, so that the connecting rod section 51 moves relative to the measuring head 4 before the measuring head 4 descends to the silt, or the connecting rod section 51 follows the measuring head 4 and is inserted into the silt. The displacement of the connecting rod section relative to the measuring head 4 is small, and the electrical conduction between the first guide plate 61 and the second guide plate 62 cannot be achieved, which affects the accurate measurement of the water body height.

[0058] In some embodiments, a scale is provided on the traction rope 31 to facilitate direct reading of the length of the traction rope 31 submerged in the water body.

[0059] Optionally, the traction rope 31 is a measuring tape.

[0060] In some embodiments, the end of the measuring head 4 away from the traction rope 31 is tapered. Setting one end of the measuring head 4 to a cone facilitates the sinking of the measuring head 4 to increase the accurate measurement of the length of the traction rope 31 submerged in the water body, thereby ensuring accurate measurement of the actual height of the water body.

[0061] In some embodiments, Figure 1 As shown, the bracket 2 is L-shaped and includes a vertical rod 21 and a horizontal rod 22 . The wire reel 3 is rotatably disposed on the vertical rod 21 . A guide wheel 8 is rotatably disposed on the horizontal rod 22 . The traction rope 31 is provided with the guide wheel 8 .

[0062] The bracket 2 is set to be L-shaped, so as to ensure that the bracket 2 is partially suspended above the water tank 1 to facilitate the release of the traction rope 31. At the same time, a guide wheel is set to guide the traction rope 31, thereby facilitating the release of the traction rope 31 and the sinking of the measuring head 4.

[0063] Optionally, the horizontal rod 22 is rotatably arranged on the water tank 1 around the position connected to the vertical rod 21, so as to adjust the falling position of the measuring head 4 on the water tank 1, i.e. the measuring point, and then multi-point detection can be performed to ensure the accuracy of water height detection.

[0064] Optionally, the length of the horizontal rod 22 is adjustable or the position of the guide wheel on the horizontal rod 22 is adjustable to facilitate adjustment of the falling position of the measuring head 4 on the water tank 1, i.e., the measuring point, so that multi-point detection can be performed to ensure the accuracy of water height detection.
