[0002] During the operation of a drum shearer in cutting coal seams, a large amount of dust is generated, and a large amount of heat is generated by the gear transmission in the cutting, traction, and height adjustment gearboxes. A large amount of water is required for spray dust suppression and cooling the motor, gears, bearings, and housings in the gearbox, so that the shearer can work normally and reliably.

[0003] The existing cooling water of the shearer is integrated, and its water supply control method is that the pump station of the centralized control system controls the start and stop of the shearer, which is a control method of other control and non-closed loop; when the shearer stops or is under maintenance, the water supply pump station of the centralized control system is always in operation, and the shearer always sprays cooling water, which has nothing to do with the working state of the shearer. It is necessary to manually control the water supply of the shearer. When the operation is not timely or not carried out, this causes unnecessary waste of water resources, and there will also be a large amount of water in the cut coal flow, affecting the coal shoveling and loading of the scraper.

[0029] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0030] <Embodiment>

[0031] As shown in the Figures 1 to 5 accompanying drawings, this embodiment discloses a water inlet control device 100 for a shearer, which is arranged between the pump station (not shown in the figure) of the centralized control system and the water inlet valve group 200 of the shearer, and is used for controlling the water inlet of the shearer. Compared with the existing method in which the pump station is directly connected to the water inlet valve group of the shearer for water supply and provides a constant water flow, this embodiment can realize the automatic control of the on / off of the cold water passage of the shearer, and does not require manual communication to start and stop the water flow.

[0032] Specifically, as shown in the Figure 2 and Figure 3 accompanying drawings, the water inlet control device 100 for a shearer includes: a water inlet joint 10, an information acquisition module, a filtering module, a communication module, and a control module 20.

[0033] The water inlet joint 10 is connected between the pump station and the water inlet valve group 300 through pipelines 11 and 12, can be opened and closed, and can adjust the size of the opening and closing, so as to be able to adjust the water inlet flow rate of the pump station.

[0034] The information acquisition module is arranged on the pipeline 11 between the water inlet joint 10 and the water inlet valve group 300, and is used for acquiring the water flow information in the pipeline. In the specific implementation manner, the pressure information of the water flow in the pipeline and the like can be acquired.

[0035] The filtering module is arranged on the pipeline and is used for filtering the water inlet from the pump station to prevent the water source provided by the pump station from containing more impurities or minerals, thus causing rust or damage to the internal components of the shearer and improving the service life of the components. As shown in the Figure 2 accompanying drawings, the filtered impurities and the like are discharged through the standby pipeline 13.

[0036] The communication module is communicatively connected to the pumping station, for example, by wireless means, and is used to send matching control instruction information to the pumping station so that the pumping station can timely control the start and stop of water intake.

[0037] The control module 20 controls the water intake of the water intake joint 10 based on the water flow information collected by the information collection module, including starting the water intake, adjusting the water intake flow rate, and stopping the water intake. By controlling the start and stop of water intake and the water volume control, water resources can be saved, and the operability and maintenance safety of the shearer can be improved.

[0038] In a specific embodiment, the control module 20 has a manual switch 21 for convenient manual operation by humans. For example, in case of emergency or control failure, etc., humans can directly control it manually, improving the redundancy of the control device.

[0039] In a specific embodiment, as Figure 4 shown, the water intake joint 10 with a self - generating battery - equipped sensor can be adopted. That is, an integrated structure can be used. While integrating multiple functions, it can effectively reduce the overall volume and weight of the device, facilitating installation. This integrated structure is compatible with functions such as adjusting the size of the water inlet, realizing information collection, wireless communication, and control, and can also generate electricity by itself and store electrical energy, so that it can work normally without an additional power supply device. When a failure or power outage occurs in the shearer, it can also timely control the stop of water intake to avoid wasting water sources.

[0040] In another embodiment, the water intake control device 100 for the shearer further includes a protection device 30, which is used to encapsulate the water intake joint 10, the information collection module, the filtering module, the communication module, and the control module 20, thereby protecting these components, preventing damage caused by coal blocks or other unexpected collisions, and improving the reliability of the device.

[0041] Specifically, the protection device 30 includes a bottom plate 31, a plurality of supporting side plates 32, and a cover plate 33. An accommodation space 34 is formed among them. The water intake joint 10, the information collection module, the filtering module, the communication module, and the control module 20 are all fixed on the bottom plate 31. The pipelines on both sides of the water intake joint 10 penetrate through two supporting side plates 32 arranged along the water supply direction.

[0042] One side of the accommodation space 34 is an open - mouth structure, thus providing a maintenance space.

[0043] In addition, in a specific embodiment, the bottom plate 31 has a first bending part 311. The two supporting side plates 32 arranged along the water supply direction are L - shaped, so as to match the first bending part 311. After being fixedly connected, the bottom plate 31 has sufficient strength to avoid damage caused by collision. Through - holes 321 are provided on both of the two supporting side plates 32 arranged along the water supply direction for the pipelines to pass through.

[0044] In another specific embodiment, the cover plate 33 has a second bending portion 331 and is adaptively arranged with the manual switch of the control module 20, so as to provide the setting space required for the manual switch, and can also improve the strength of the cover plate 33 to avoid damage caused by collision.

[0045] According to the water inlet control device for a shearer involved in this embodiment, it is installed between the pump station of the centralized control system and the water inlet valve group of the shearer. By collecting the water flow information in the pipeline, the opening and closing size of the water inlet joint is controlled, realizing the automatic control of the on-off of the cooling water of the shearer, which can not only ensure the cooling and dust reduction needs of the shearer, but also avoid indirectly affecting the efficiency of the shearer due to the large traction force caused by water resource waste.

[0046] The protection scope of the present invention is not limited to the above embodiments. Obviously, those skilled in the art can make various changes and deformations to the present invention without departing from the scope and spirit of the present invention. If these changes and deformations belong to the scope of the claims of the present invention and its equivalent technologies, the intention of the present invention also includes these changes and deformations.
