Description

Technical Field

[0001] The utility model relates to the technical field of mine auxiliary transportation, in particular to a mechanical belt automatic water supply device. Background Art

[0002] Due to the complex conditions of the belt lane, there is a lot of dust on site during belt operation, and the explosion-proof requirements of the equipment need to be considered. General electrical equipment cannot meet the on-site requirements. Due to the length of the belt lane, the operating cost of using explosion-proof equipment is relatively high.

[0003] At present, in order to meet the explosion-proof requirements of equipment, manual water supply is required to reduce the spread of dust. The manpower cost is high, which is not only time-consuming and labor-intensive, but also poses certain safety hazards when manually supplying water. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a mechanical belt automatic water supply device. When the belt is running, it will drive the transmission mechanism to drive the shaft sleeve of the water supply device to rotate, and the rocker arm will begin to flip toward the location of the automatic reset water valve under the action of centrifugal force, thereby driving the push rod to move toward the location of the automatic reset water valve. At this time, the control valve core of the automatic reset water valve is opened under the action of the repulsive force of the magnet, thereby realizing automatic water supply, thereby reducing dust caused by the operation of the belt.

[0005] In order to solve the above technical problems, the technical solution of the utility model is implemented as follows:

[0006] A mechanical belt automatic water supply device, the water supply device comprises a protective cover, the interior of the protective cover is rotatably connected to a shaft sleeve through a transmission mechanism;

[0007] The outer side of the shaft sleeve is fixed with a plurality of push rods distributed in an array along the circumferential direction thereof, and a plurality of swing rods are movably connected to the push rods, and a strong magnet 1 is fixed to a common end of all the push rods, and an automatic reset water valve is also fixed in the protective cover through a water valve mounting seat, and a strong magnet 2 facing the strong magnet 1 is fixed on the control valve core of the automatic reset water valve, and the strong magnet 1 and the strong magnet 2 are located on the same straight line and repel each other, and the swing rod is tilted away from the location of the automatic reset water valve;

[0008] When the shaft sleeve is driven to rotate by the transmission mechanism, the swing arm begins to flip toward the location of the automatic reset water valve under the action of centrifugal force, thereby driving the push rod to move toward the location of the automatic reset water valve. At this time, the control valve core of the automatic reset water valve is opened under the action of the repulsive force of the magnet.

[0009] By adopting the above scheme, when the belt is running, it will drive the transmission mechanism to cause the shaft sleeve of the water supply device to rotate, and the rocker arm will begin to flip toward the location of the automatic reset water valve under the action of centrifugal force, thereby driving the push rod to move toward the location of the automatic reset water valve. At this time, the control valve core of the automatic reset water valve is opened under the action of the repulsive force of the magnet, thereby realizing automatic water supply, thereby reducing dust caused by the operation of the belt.

[0010] As a preferred embodiment of a mechanical belt automatic water supply device, a counterweight is fixed to one end of the swing arm away from the push rod; wherein the counterweight is a standardized counterweight ball, and the center of gravity of the counterweight ball is at the center of the ball.

[0011] By adopting the above scheme, in order to increase the centrifugal force of the swing rod when it rotates, a counterweight block is added to increase the centrifugal force, thereby increasing the driving force when the push rod moves toward the location of the automatic reset water valve.

[0012] As a preferred embodiment of a mechanical belt automatic water supply device, the tilt angle between the swing arm and the horizontal plane is 30-85°;

[0013] When the shaft sleeve is not driven to rotate by the transmission mechanism, the tilt angle between the swing rod and the horizontal plane is the smallest, wherein the tilt angle is 30°;

[0014] When the shaft sleeve is driven to rotate by the transmission mechanism, the tilt angle between the swing rod and the horizontal plane increases with the increase of the rotation speed, wherein the maximum tilt angle is 85°.

[0015] By adopting the above scheme, when the sleeve is driven to rotate by the transmission mechanism, all the push rods rotate together with the sleeve. During the rotation, the swing arm will gradually swing toward the location of the automatic reset water valve under the action of centrifugal force. At this time, the inclination angle between the swing arm and the horizontal plane increases with the increase of the rotation speed. During the increase of the angle, a horizontal force will be generated under the action of centrifugal force, and this force will push the push rod to move toward the location of the automatic reset water valve.

[0016] As a preferred embodiment of a mechanical belt automatic water supply device, both sides of the automatic reset water valve are connected to water pipes, which extend outside the protective cover.

[0017] By adopting the above scheme, when the control valve core of the automatic reset water valve is opened, the water in the water pipe will flow, thereby realizing water supply.

[0018] As a preferred implementation of a mechanical belt automatic water supply device, two mutually symmetrical positioning frames are fixed to the outside of the protective cover, and the positioning frames are fixed to the column through a fixing seat.

[0019] By adopting the above solution, in order to realize the positioning of the protective cover, the protective cover is fixed on the column through a positioning frame, thereby ensuring stability and reliability during water supply.

[0020] As a preferred embodiment of a mechanical belt automatic water supply device, the transmission mechanism includes a roller, a transmission shaft is coaxially connected to the roller, and the roller is connected to the shaft sleeve through the transmission shaft;

[0021] Wherein, the transmission shaft is rotatably connected to two sets of bearing seats;

[0022] Among them, the roller is a kind of friction wheel, and the roller rotates through belt drive.

[0023] In order to realize transmission by adopting the above scheme, the belt contacts the roller, and drives the roller to rotate under the action of friction, and then realizes the transmission of the sleeve through the transmission shaft.

[0024] After adopting the above technical solution, the beneficial effects of the utility model are:

[0025] 1. When the belt is running, it will drive the transmission mechanism to drive the shaft sleeve of the water supply device to rotate. Under the action of centrifugal force, the swing arm begins to flip toward the location of the automatic reset water valve, thereby driving the push rod to move toward the location of the automatic reset water valve. At this time, the control valve core of the automatic reset water valve is opened under the action of the repulsive force of the magnet, thereby realizing automatic water supply, thereby reducing dust caused by the operation of the belt.

[0026] 2. In order to increase the centrifugal force of the swing arm during rotation, a counterweight block can be added to increase the centrifugal force, thereby increasing the driving force when the push rod moves toward the location of the automatic reset water valve.

[0027] 3. When the shaft sleeve is driven to rotate by the transmission mechanism, all the push rods rotate together with the shaft sleeve. During the rotation, the swing rod will gradually swing toward the location of the automatic reset water valve under the action of centrifugal force. At this time, the inclination angle between the swing rod and the horizontal plane increases with the increase of the rotation speed. During the increase of the angle, a horizontal force will be generated under the action of centrifugal force, and this force will push the push rod to move toward the location of the automatic reset water valve.

[0028] 4. In order to achieve transmission, a belt contacts the roller, which drives the roller to rotate under the action of friction, and then the transmission of the sleeve is achieved through the transmission shaft. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] like Figure 1 to Figure 2 As shown, a mechanical belt automatic water supply device comprises a protective cover 1, the interior of the protective cover 1 is rotatably connected to a shaft sleeve 10 through a transmission mechanism;

[0037] The outer side of the shaft sleeve 10 is fixed with a plurality of push rods 11 distributed in an array along the circumferential direction thereof, and the push rods 11 are movably connected with a plurality of swing rods 8, and a strong magnet 12 is fixed to a common end of all the push rods 11, and an automatic reset water valve 14 is also fixed in the protective cover 1 through a water valve mounting seat 15, and a strong magnet 2 13 facing the strong magnet 1 12 is fixed to the control valve core of the automatic reset water valve 14, and the strong magnet 1 12 and the strong magnet 2 13 are located on the same straight line and repel each other, and the swing rod 8 is tilted away from the location of the automatic reset water valve 14;

[0038] When the shaft sleeve 10 is driven to rotate by the transmission mechanism, the rocker arm 8 begins to flip toward the location of the automatic reset water valve 14 under the action of centrifugal force, thereby driving the push rod 11 to move toward the location of the automatic reset water valve 14. At this time, the control valve core of the automatic reset water valve 14 is opened under the action of the repulsive force of the magnet.

[0039] When the belt is running, it will drive the transmission mechanism to drive the shaft sleeve 10 of the water supply device to rotate, and the rocker arm 8 begins to flip toward the location of the automatic reset water valve 14 under the action of centrifugal force, thereby driving the push rod 11 to move toward the location of the automatic reset water valve 14. At this time, the control valve core of the automatic reset water valve 14 is opened under the action of the repulsive force of the magnet, thereby realizing automatic water supply, thereby reducing dust caused by the operation of the belt.

[0040] like Figure 2 As shown, a counterweight 9 is fixed to one end of the swing rod 8 away from the push rod 11; the counterweight 9 is a standardized counterweight ball, and the center of gravity of the counterweight ball is at the center of the ball. In order to increase the centrifugal force of the swing rod 8 when rotating, the counterweight 9 is added to increase the centrifugal force, thereby increasing the driving force when the push rod 11 moves toward the location of the automatic reset water valve 14.

[0041] like Figure 3 to Figure 4 As shown, the tilt angle between the swing rod 8 and the horizontal plane is 30-85°;

[0042] When the shaft sleeve 10 is not driven to rotate by the transmission mechanism, the tilt angle between the swing rod 8 and the horizontal plane is the smallest, wherein the tilt angle is 30°;

[0043] When the shaft sleeve 10 is driven to rotate by the transmission mechanism, the tilt angle between the rocker arm 8 and the horizontal plane increases with the increase of the rotation speed, wherein the maximum tilt angle is 85°.

[0044] When the sleeve 10 is driven to rotate by the transmission mechanism, all the push rods 11 rotate together with the sleeve 10. During the rotation, the swing rod 8 will gradually swing toward the location of the automatic reset water valve 14 under the action of centrifugal force.

[0049] The roller 5 is a kind of friction wheel, and the roller 5 rotates through belt drive.

[0050] In order to realize transmission, the belt contacts the roller 5 , and drives the roller 5 to rotate under the action of friction force, and then realizes the transmission of the sleeve 10 through the transmission shaft 6 .

[0051] The working principle of this utility model:

[0052] When in use, the belt contacts the roller 5 , and the roller 5 is driven to rotate under the action of friction force, and then the transmission of the shaft sleeve 10 is realized through the transmission shaft 6 .

[0053] When the shaft sleeve 10 is driven to rotate by the transmission mechanism, all the push rods 11 rotate together with the shaft sleeve 10. During the rotation, the swing rod 8 will gradually swing toward the location of the automatic reset water valve 14 under the action of centrifugal force. At this time, the inclination angle between the swing rod 8 and the horizontal plane increases with the increase of the rotation speed. During the increase of the angle, a horizontal force will be generated under the action of centrifugal force. Under this force, the push rod 11 will be pushed to move toward the location of the automatic reset water valve 14. At this time, the control valve core of the automatic reset water valve 14 will open, and the water in the water pipe will flow, thereby realizing automatic water supply, thereby reducing dust caused by the operation of the belt.
